The light source unit 180 includes a light source 181 and a light guide column 182 for generating light to form a luminous key.

Specifically, the base 110 can be disposed on a bottom board or a printed circuit board. In this embodiment, the base 110 is disposed on the circuit board 190 as an example, but it is not limited thereto. In other embodiments, when the base 110 is disposed on the base plate, the circuit board can be selectively disposed above or below the base plate according to practical applications. In one embodiment, the base 110 and the circuit board 190 are preferably positioned by a positioning mechanism. For example, the base 110 can have a positioning column 112, and the circuit board 190 can have a socket 191 corresponding to the positioning column 112, so that the base 110 can be fixed on the circuit board 190 by inserting the positioning column 112 into the socket 191, but not in this way. limit. In other embodiments, the positions of the positioning post and the insertion hole can also be interchanged, or the base 110 can be positioned on the lower board (such as the circuit board 190 or the bottom board) by locking, adhering, bearing and other methods.

The base 110 is preferably a lower case extending along the directions of the X-axis, Y-axis and Z-axis, and the cover 120 is an upper case corresponding to the base 110 . The base 110 is preferably combined with the cover 120 to form a housing with an accommodating space for accommodating the restoring unit 140 , the elastic handle 150 , the electrode module 170 , the light source unit 180 and the like. For example, the base 110 may have a buckle portion 119 , and the cover 120 may have a buckle hole 121 , so that the base 110 and the cover 120 are fastened together along the Z-axis direction through the buckle portion 119 and the buckle hole 121 .

Specifically, the first electrode piece 171 and the second electrode piece 172 are preferably respectively inserted into the first electrode hole 114 and the second electrode hole 115, and then protrude below the base 110 and connect with the first contact hole 192 and the second contact hole 192. The holes 193 are electrically connected, but not limited thereto. In other embodiments, the circuit board 190 may not have contact holes, and the first electrode pad 171 and the second electrode pad 172 may be electrically connected to the surface contact area of the circuit board 190 .

The first electrode piece 171 has an elastic portion 1711, and the elastic portion 1711 is arranged corresponding to the actuating portion 132 of the key shaft 130, so that the first electrode piece 171 and the second electrode piece 712 are selectively contacted according to the movement of the actuating portion 132, and then is triggered to generate a trigger signal. For example, when the button structure 10 is in the unpressed position, the apex of the protrusion of the actuating part 132 pushes outward against the elastic part 1711 away from the second electrode piece 172, so that the first electrode piece 171 is not in contact with the second electrode piece 172 or not conducting without generating a trigger signal. When the key shaft 130 is pressed and moves toward the base 110, the key shaft 130 drives the actuating part 132 to move downward so that the apex of the protrusion passes over the elastic part 1711, so that the elastic part 1711 rebounds toward the second electrode piece 172, and then the second One electrode piece 171 contacts or conducts with the second electrode piece 172 to generate a trigger signal.

It should be noted here that although the key structure 10 is described by taking the electrode module 170 as a switch component as an example, it is not limited thereto. In other embodiments, the key structure 10 may selectively generate a trigger signal in response to the movement of the key shaft 130 through other forms of switch components. For example, the key structure 10 may include a light transmitter and a light receiver electrically connected to the circuit board 190 as a switch component (ie, an optical axis switch), so that the key structure 10 can change the light when the key shaft 130 moves toward the base 110. The receiver generates a trigger signal from the amount of light received by the light transmitter.

Moreover, the base 110 preferably further has an accommodating area 117 (as shown in FIG. 2A ) for disposing the torsion spring body 153 of the elastic handle 150 . For example, the accommodating area 117 can be a space partitioned by a plurality of walls of the base 110 to limit the range of motion of the elastic handle 150 . When the adjusting member 160 pushes the positioning portion 151 , the torsion spring body 153 can be confined in the accommodating area 117 to cause different deformations of the elastic feel member 150 . Moreover, the base 110 may further have a striking portion 118 (as shown in FIG. 2A ), which is used for the extension arm 152 to strike to generate a sound. For example, the impact portion 118 can be a convex wall protruding from the bottom of the base 110 toward the cover 120 , and the wall surface of the convex wall facing the extension arm 152 is the impact surface 1181 . When the handle elastic member 150 is disposed on the base 110 , the positioning portion 151 is inserted into the positioning hole 111 , the torsion spring body 153 is positioned in the accommodating area 117 , and the extension arm 152 extends through the movement path of the actuating portion 131 of the key shaft 130 . That is, the positioning part 151 is inserted into the positioning hole 111 substantially along the Z-axis direction and is at least partially located in the opening part 116 , and the extension arm 152 substantially extends through the lower part of the actuating part 131 along the X-axis direction.

The connecting portion 162 is disposed below the circuit board 190 , and the adjusting rod 161 is connected to the connecting portion 162 and protrudes toward the cover 120 (eg, Z-axis direction). For example, the circuit board 190 has a moving groove 194 corresponding to the opening 116, and the adjusting rod 161 is inserted into the moving groove 194 upward from the bottom of the circuit board 190, and then extends into the opening 116 to correspond to the positioning portion 151 protruding from the positioning hole 111 below. . When the adjusting member 160 moves, the adjusting rod 161 can drive the positioning portion 111 to move, thereby causing the elastic handle 150 to have different deformations. In one embodiment, the adjusting rod 161 preferably has a limiting groove 1611 , and the limiting groove 1611 is preferably disposed along the length direction (eg Z-axis direction) of the adjusting rod 161 to correspond to the long axis direction of the positioning portion 151 . For example, the limit slot 1611 can be an open channel opened on the wall surface of the adjustment rod 161 facing the positioning portion 151 (for example, parallel to the XZ plane), so that the positioning portion 151 is at least partially accommodated in the limit after the positioning portion 151 is inserted into the positioning hole 111. The positioning groove 1611 further strengthens the linkage positioning between the adjusting rod 161 and the positioning part 151, and reduces the chance of the positioning part 151 slipping off from the adjusting rod 161 when the positioning part 151 moves, but it is not limited thereto. In other embodiments, the limiting groove 1611 can be a hole opened downward from the top surface of the adjusting rod 161 (for example, parallel to the XY plane), for the positioning part 151 to be inserted into the adjusting rod 161 . In addition, according to practical applications, the adjusting rod 161 may not have the limiting groove 1611 , and the wall surface of the adjusting rod 161 abuts against the positioning portion 151 .

Referring to FIG. 3A and FIG. 3B , the operation of adjusting the pressing feel of the button structure 10 of the present invention using the adjusting member 160 will be described, wherein FIG. 3A and FIG. 3B are schematic cross-sectional views along the tangent line AA of FIG. 1C . As shown in FIG. 3A , when the handle elastic member 150 is disposed on the base 110, the torsion spring body 153 is located in the accommodation area 117, the positioning portion 151 is inserted downward into the positioning hole 111 and at least partially abuts against the adjustment rod 161 (for example, at least partially inserted limiting slot 1611 ), and the extension arm 152 extends below the actuating portion 131 . In this embodiment, the adjusting member 160 is preferably movable toward the extension direction of the extension arm 152 (for example, the X-axis direction), so as to change the deformation of the feel elastic member 150 , thereby changing the preload of the feel elastic member 150 . As shown in FIG. 3B , when the adjusting rod 161 moves along the X-axis direction, the adjusting rod 161 drives the positioning portion 151 to move in the positioning hole 111 along the X-axis direction, so that the positioning portion 151 and the extension arm 152 are relative to the torsion spring body 153. Changes in position (that is, different deformations), that is, changes in the preload of the torsion spring, can then change the actuation relationship between the actuating part 131 and the elastic handle 150 to provide different pressing feels, such as pressing with different pressing forces, Frustrated feel, linear feel. In other words, when the moving distance of the adjustment member 160 along the X-axis direction is different, the torsion spring can have different preloads, or the position of the extension arm 152 relative to the action path of the actuating part 131 can be different, so as to provide different Press feel.

Referring to the drawings later, the moving position of the adjusting member 160 along the X-axis direction and the corresponding feel provided by the key structure 10 will be described in detail. 4A and 4B are respectively a top view of the key structure 10 in FIG. 1A in the first state and a cross-sectional view along the tangent line BB in FIG. 4A . As shown in FIG. 4A and FIG. 4B , when the button structure 10 is in the first state, the adjustment member 160 abuts against the positioning portion 151 and is located at the first position in the X-axis direction. At this time, the elastic handle 150 has the first deformation, so that the pressing force required to move the key shaft 130 toward the base 110 and drive the moving part 131 over the extension arm 152 is the first pressing force. For example, the first position may be the position of the adjusting member 160 when the key structure 10 is in a default state, so that the first pressing force is a preset pressing force. When the adjustment member 160 is at the first position, the extension arm 152 preferably passes through the action path when the actuating part 131 moves downward (that is, the action path is parallel to the Z-axis direction), and the extension arm 152 is located at the first position relative to the action path. . When the adjustment member 160 is at the first position, when the first pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving part 131 to move, and the extension arm 152 first moves downward and along the lower contact surface 1311 Slide to the apex 1313 , and after passing the apex 1313 , move upwards and hit the base 110 or the cover 120 to generate a sound (for example, the first sound). In other words, when the handle elastic member 150 has the first deformation and the key shaft 130 is pressed, the extension arm 152 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 152 reaches the apex 1313 after sliding a first distance on the lower contact surface 1311, extending After the arm 152 passes over the apex 1313 later, it moves upwards away from the protrusion. It should be noted here that when the extension arm 152 reaches the apex 1313 , there is a first sounding distance between the extension arm 152 and the impact surface of the base 110 or the cover 120 , and the extension arm 151 strikes the impact surface to generate the first sound. In this embodiment, the impact surface may be a wall surface of the cover body 120 or the base 110 corresponding to the extension arm 152 , such as the impact surface 1181 of the impact portion 118 of the base 110 .

5A and 5B are respectively a top view and a cross-sectional view along the tangent line BB in FIG. 5A of the button structure 10 in FIG. 1A when it is in the second state. As shown in FIG. 5A and FIG. 5B , when the button structure 10 is in the second state, the adjustment member 160 abuts against the positioning portion 151 and is located at the second position in the X-axis direction. At this time, the elastic feel member 150 has the second deformation, so that the pressing force required to move the key shaft 130 toward the base 110 and drive the moving part 131 over the extension arm 152 is the second pressing force. For example, the second position of the adjusting member 160 can be closer to the actuating portion 131 than the first position, that is, the adjusting rod 161 moves toward the inner side of the base 110 and pushes the positioning portion 151 inward, so that the preload of the elastic member 150 can be felt. Increase. When the adjustment member 160 is at the second position, the extension arm 152 preferably passes through the action path when the actuating part 131 moves downward, and the extension arm 152 is at the second position relative to the action path. Specifically, the second position of the extension arm 152 is closer to the outside of the base 110 than the first position, that is, closer to the apex 1313 of the actuating portion 131 in the Y-axis direction. When the adjustment member 160 is at the second position, when the second pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving part 131 to move, and the extension arm 152 first moves downward and along the lower contact surface 1311 Slide to the apex 1313 , and after passing the apex 1313 , move upwards and hit the impact surface of the base 110 or the cover 120 to generate a sound (such as a second sound). In other words, when the handle elastic member 150 has the second deformation, the extension arm 152 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 152 reaches the apex 1313 after sliding a second distance on the lower contact surface 1311, and the extension arm 152 later After crossing the apex 1313, it moves upwards away from the bump. In this embodiment, because the extension arm 152 is closer to the apex 1313 than the first position when the extension arm 152 is in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 152 reaches the apex 1313 , there is a second distance between the extension arm 152 and the impact surface, and the extension arm 151 hits the impact surface to generate a second sound.

Specifically, when the adjustment member 160 is located at the first position or the second position, the preload generated by the deformation of the handle elastic member 150 is preferably still within the range where the actuating part 131 can push the extension arm 152 downward. Therefore, when a sufficient pressing force (for example, the first pressing force or the second pressing force) is applied to the key shaft 130, the extension arm 152 will first move downwards and slide along the lower contact surface 1311 under the downward thrust of the actuating part 131. Go to the apex 1313 , and after passing the apex 1313 , move upwards by the rebound force and hit the impact surface (for example, 1181 ) of the base 110 or the cover 120 to generate a sound. It should be noted here that in this embodiment, when the adjustment member 160 is in the second position, the position of the extension arm 152 relative to the motion path is different from the position of the extension arm 152 relative to the motion path when the adjustment member 160 is in the first position. The location of the path. That is to say, when the adjustment member 160 is at the first position, the first sounding distance between the extension arm 152 and the impact surface 1181 is different from the distance between the extension arm 152 and the impact surface 1181 when the adjustment member 160 is at the second position. Second utterance pitch. For example, when the adjustment member 160 moves from the first position to the second position, the positioning portion 151 of the elastic handle 150 is pushed and displaced by the adjustment rod 161, so that the elastic handle 150 changes from the first deformation to the second deformation. deformation, and then the preload of the handle elastic member 150 is increased from the first preload to the second preload. Therefore, the distance that the extension arm 152 is pushed downward by the actuating part 131 when it is in the first position is greater than the distance that the extension arm 152 is pushed downward by the actuation part 131 when it is in the second position, that is, the distance between the first sound is greater than that of the second sound. distance so that the volume of the first sound is greater than the volume of the second sound. In other words, when the preload caused by the deformation of the elastic feel member 150 is larger, the displacement of the extension arm 152 relative to the impact surface 1181 is smaller, and therefore the generated sound is smaller.

Furthermore, when the adjustment member 160 moves toward the inner side of the base 110 along the X-axis direction, the greater the relative displacement of the positioning portion 151 is, the greater the preload of the torsion spring becomes. When the pre-compression of the torsion spring reaches a certain level, the force of the torsion spring is too large, and the key shaft 130 cannot press down the torsion spring, and the extension arm 152 is pushed out from the side, resulting in a frustrating feel. 6A and 6B are respectively a top view and a cross-sectional view of the button structure 10 in FIG. 1A in the third state and a cross-sectional view along line BB in FIG. 6A . As shown in FIGS. 6A and 6B , when the button structure 10 is in the third state, the adjustment member 160 abuts against the positioning portion 151 and is located at a third position in the X-axis direction. At this time, the elastic handle 150 has a third deformation, so that the extension arm 152 is located at a third position relative to the motion path. Specifically, the third position of the adjustment member 160 can be deeper into the inner side of the base 110 than the second position, so that the extension arm 152 preferably substantially corresponds to the apex 1313 of the actuating portion 131 at the third position. In other words, the adjustment rod 161 moves further into the base 110 and further pushes the positioning portion 151 inward, so that the preload of the handle elastic member 150 increases, and the actuating portion 131 cannot push the extension arm 152 downward. Therefore, when the adjustment member 160 is at the third position and a pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving part 131 to push the extension arm 152 outward along the Y-axis direction toward the moving path, thereby generating Feeling frustrated. At this time, since the actuating part 131 does not press down on the extension arm 152 , the extension arm 152 only displaces laterally, but does not press down and rebound to hit the impact surface 1181 , so no sound will be generated.

Moreover, when the adjustment member 160 moves along the X-axis direction so far that the elastic member 150 is deformed and the position is shifted, and the extension arm 152 is outside the action path of the actuating portion 131 , the key structure 10 can provide a linear feel. 7A and 7B are respectively a top view and a cross-sectional view of the button structure 10 in FIG. 1A in the fourth state and a cross-sectional view along line BB in FIG. 7A . As shown in FIG. 7A and FIG. 7B , when the button structure 10 is in the fourth state, the adjustment member 160 abuts against the positioning portion 151 and is located at a fourth position in the X-axis direction. At this time, the elastic feel member 150 has a fourth deformation, so that the extension arm 152 is located at a fourth position outside the action path of the actuating part 131 . For example, the fourth position of the adjusting member 160 can be deeper inside the base 110 than the third position. The preload increases, and the extension arm 152 displaces in the direction of the Y axis and deviates from the action path of the actuating part 131 . Specifically, when the adjusting member 160 is at the fourth position, the extension arm 152 is at the fourth position outside the action path of the actuating part 131, so when pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and The moving part 131 is driven to move along the moving path without interfering with the extension arm 152 to produce a linear feel.

It should be noted here that although the embodiments of FIGS. 4A to 7B sequentially show that the adjustment member 160 moves in different positions along the X-axis direction toward the inside of the base 110, the adjustment member 160 can also move toward the outside of the base 110 in different positions along the X-axis direction. position, and the positioning portion 151 can move with the adjustment member 160 toward the outside of the base 110 by the elastic recovery force of the deformation, so as to have a deformation corresponding to the position of the adjustment member 160 in the X-axis direction, thereby providing a corresponding pressing feel. Specifically, according to practical applications, the button structure 10 can selectively provide more than two kinds of pressing sensations by controlling the position of the adjustment member 160 in the X-axis direction. In other words, the adjustment member 160 can move inwardly or outwardly of the base 110 in the direction of the X-axis to selectively control the position of the adjustment member 160 to (1) make the deformation (or preload) of the elastic member 150 on the key shaft 130 moves toward the base 110 and drives the actuating part 131 to move, the actuating part 131 can press down the extension arm 152, so that the extension arm 152 is displaced in the Z-axis direction and then strikes the position of the impact surface 1181 (for example, in the X-axis direction the first position, the second position, or any suitable position before reaching the third position), and can provide a variety of different pressing force feel, and can also emit sounds of different volumes; (2) make the feel of the elastic member 150 Deformation (or preload) When the key shaft 130 moves toward the base 110 and drives the moving part 131 to move, the moving part 131 pushes out the position of the extension arm 152 toward the outside of the moving path (for example, the third position in the X-axis direction), But it can provide a silent feeling of frustration; or (3) the deformation (or preload) of the elastic member 150 makes the extension arm 152 located outside the action path, when the key shaft 130 moves toward the base 110 and drives the moving part 131 to move , the actuating part 131 will not interfere with the extension arm 152 (for example, the fourth position in the X-axis direction), and can provide a silent linear feel.

In this embodiment, the composite elastic member 240 includes a spring body 243 , a positioning portion 241 and an extension arm 242 . The spring body 243 is disposed between the base 210 and the key shaft 130 to provide a restoring force to move the key shaft 130 away from the base 210 .

The X-axis adjustment member 261 is disposed corresponding to the positioning portion 241 , and the Y-axis adjustment member 262 is disposed corresponding to the extension arm 242 .

Specifically, the spring body 243 is similar to the restoring unit 140 in the embodiment of FIG. 1A , and can be in the form of a spring. The positioning portion 241 and the extension arm 242 are preferably formed by bending a rod extending from one end (eg, the lower end) of the spring body 243 , and the positioning portion 241 and the extension arm 242 are used as elastic parts for the key structure 20 . In this embodiment, the positioning portion 241 preferably includes a horizontal portion 2411 and an upright portion 2412 . The horizontal portion 2411 is connected between the upright portion 2412 and the spring body 243 , and the horizontal portion 2411 preferably extends from one end of the spring body 243 to the positioning hole 211 of the base 210 . The upright portion 2412 is substantially bent upward toward the Z-axis direction relative to the horizontal portion 2411 , and the extension arm 242 is bent toward the X-axis direction relative to the upright portion 2412 . In this embodiment, the angle between the extension arm 242 and the upright portion 2412 is preferably no greater than 120 degrees.

Corresponding to the composite elastic part 240 and the adjusting part 260 , the base 210 has a positioning hole 211 , a channel part 212 , an opening part 216 and a limiting part 217 . In this embodiment, the positioning hole 211 is a through hole opened at the bottom of the base 210, and the opening 216 is preferably a gap partially hollowed out from the side wall adjacent to the positioning hole 211 toward the bottom of the base 110, and the opening 216 communicates with the positioning The hole 211 is used to allow the positioning part 241 to be displaced in the positioning hole 211 in response to the movement of the adjustment member 260 . The limiting portion 217 preferably corresponds to the upper section of the positioning portion 241 (ie, the portion of the upright portion 2412 adjacent to the extension arm 242 ), and is used to limit the displacement of the positioning portion 241 . Specifically, when the spring body 243 is sleeved on the positioning portion 113 of the base 210, the horizontal portion 2411 of the positioning portion 241 extends to the positioning hole 211, and the lower section of the upright portion 2412 is exposed to the opening 216 to correspond to the X-axis adjustment member 261, And the upper section of the upright portion 2412 is positioned by the limiting portion 217 , and the extension arm 242 extends below the actuating portion 131 in the X-axis direction and spans above the channel portion 212 . For example, the limiting portion 217 can be a groove formed on the wall of the base 210 , or a wall where the connection between the upright portion 2412 and the extension arm 242 can lean against. The channel portion 212 can be a through hole opened along the Y-axis direction to allow the Y-axis adjusting member 262 to move in the channel portion 212 to change the position of the extension arm 242 relative to the moving path of the actuating portion 131 .

In one embodiment, the X-axis adjusting member 261 includes an X-axis adjusting rod 2611 and an X-axis connecting portion 2612 . The X-axis connecting portion 2612 is disposed below the circuit board 290 , and the X-axis adjusting rod 2611 is connected to the X-axis connecting portion 2612 and protrudes toward the cover 120 (eg, the Z-axis direction). For example, the circuit board 290 has an X-axis moving groove 294 corresponding to the opening 216, and the X-axis adjusting rod 261 is inserted into the X-axis moving groove 294 from the bottom of the circuit board 290 upwards, and then extends into the opening 216 to be exposed in the positioning hole correspondingly. The positioning part 241 in 211 (that is, the lower section of the upright part 2412). When the X-axis adjustment part 261 moves, the X-axis adjustment rod 2611 can drive the positioning part 241 to move, so as to change the deformation of the positioning part 241 and the extension arm 242 relative to the spring body 243, and then change the key shaft 130 to move toward the base 210 and bring The moving part 131 moves relative to the extension arm 242 with a required pressing force.

For example, the circuit board 290 has a Y-axis moving groove 295 corresponding to the channel portion 212 , and the Y-axis adjusting rod 2621 is inserted into the Y-axis moving groove 295 upward from the bottom of the circuit board 290 , and then protrudes upward from the channel portion 212 to correspond to the extension arm 242 . When the Y-axis adjustment member 262 moves, the Y-axis adjustment rod 2621 can drive the extension arm 242 to move along the Y-axis direction, thereby changing the position of the extension arm 242 relative to the movement path of the actuating part 131 .

In this embodiment, the Y-axis adjusting rod 2621 preferably has a notch portion 2623 , and the notch portion 2623 is preferably recessed from the wall facing the extension arm 242 to correspond to the long axis direction of the extension arm 242 . For example, the notch 2623 can be an L-shaped notch, that is, the Y-axis adjustment rod 2621 has a stepped top surface, so that the extension arm 242 straddles the notch 2623 of the Y-axis adjustment rod 2621, thereby strengthening the Y axis. The joint positioning of the shaft adjustment rod 2621 and the extension arm 242 is not limited thereto. In other embodiments, the Y-axis adjusting rod 2621 may not have the notch 2623 , and the wall surface of the Y-axis adjusting rod 2621 abuts against the extension arm 242 . In addition, although not shown, in another embodiment, the X-axis adjusting rod 2611 can optionally have a limiting groove 1611 similar to the adjusting rod 161 in the embodiment of FIG. The following paragraphs will not be repeated here.

Referring to FIG. 10A to FIG. 10C , the operation of adjusting the pressing feel of the button structure 20 of the present invention using the X-axis adjustment member 261 will be described. FIG. 10A is a schematic diagram of the button structure in FIG. 8A without the cover, and FIG. 10B and FIG. 10C They are schematic cross-sectional views along the tangent line CC of FIG. 10A when the X-axis adjusting member is in different positions. As shown in FIG. 10B , when the X-axis adjustment member 261 is located at the first position in the X-axis direction, the X-axis adjustment rod 2611 abuts against the lower end of the upright portion 2412 of the positioning portion 241, and the positioning portion 241 and the extension arm 242 are relative to the spring body 243 has the first deformation, that is, there is a first preload between the positioning part 241 and the extension arm 242, so that the key shaft 130 moves toward the base 210 and drives the moving part 131 to move relative to the extension arm 242. The required pressing force is First pressing force. Specifically, when the X-axis adjusting member 261 is located at the first position, the extension arm 242 preferably passes through the movement path of the actuating part 131 moving downward (ie, the movement path is parallel to the Z-axis direction). When the X-axis adjustment member 261 is at the first position, when the first pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving part 131 to move, and the extension arm 242 first moves downward and collides downward. The surface 1311 slides to the apex 1313 , and after passing the apex 1313 , moves upwards to strike the base 210 or the cover 120 to generate a sound (eg, a first sound). In other words, when there is a first deformation between the positioning part 241 and the extension arm 242 (that is, the elastic handle has a first X-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 242 is below The contact surface 1313 slides a first distance and reaches the apex 1313 , and the extension arm 242 passes over the apex 1313 later, and then breaks away from the protrusion and moves upward. It should be noted here that when the extension arm 242 reaches the apex 1313 , there is a first sounding distance between the extension arm 242 and the impact surface of the base 210 or the cover 120 , and the extension arm 242 hits the impact surface to generate the first sound. In this embodiment, the impact surface may be a wall surface of the cover body 120 or the base 210 corresponding to the extension arm 242 , such as the impact surface 1181 of the impact portion 118 of the base 210 .

As shown in FIG. 10C , when the X-axis adjustment member 261 moves along the X-axis direction, for example, moves toward the inner side of the base 210 to approach the actuating portion 131 , the X-axis adjustment rod 161 pushes the lower end of the positioning portion 241 into the positioning hole 211 along the The displacement in the X-axis direction changes the positions of the positioning portion 241 and the extension arm 242 relative to the spring body 243 (ie produces different deformations), that is, changes the preload. Specifically, when the X-axis adjustment member 261 is located at the second position in the X-axis direction, the X-axis adjustment rod 2611 abuts against the lower end of the upright portion 2412 of the positioning portion 241 , and the positioning portion 241 and the extension arm 242 have The second deformation, that is, there is a second preload between the positioning part 241 and the extension arm 242, so that the key shaft 130 moves toward the base 210 and drives the moving part 131 to move relative to the extension arm 242. The required pressing force is the second. Press pressure. Specifically, when the X-axis adjustment member 261 is located at the second position in the X-axis direction, the extension arm 242 preferably passes through the moving path of the actuating part 131 moving downward (ie, the moving path is parallel to the Z-axis direction). When the X-axis adjustment member 261 is located at the second position in the X-axis direction, and the second pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving part 131 to move, and the extension arm 242 first goes down. Move and slide along the lower contact surface 1311 to the apex 1313 , and after passing the apex 1313 , move upwards and hit the base 210 or the cover 120 to generate a sound (such as a second sound). In other words, when there is a second deformation between the positioning portion 241 and the extension arm 242 (that is, the elastic handle has a second X-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 242 is below The contact surface 1311 slides a second distance and reaches the apex 1313 , and the extension arm 242 passes over the apex 1313 later, and then moves upwards away from the bump. In this embodiment, because the extension arm 242 is closer to the apex 1313 than the first position when the extension arm 242 is in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 242 reaches the apex 1313 , there is a second distance between the extension arm 242 and the impact surface (for example 1181 ) of the base 210 or the cover 120 , and the extension arm 242 strikes the impact surface to generate a second sound.

In this embodiment, when the X-axis adjustment member 261 moves from the first position to the second position in the X-axis direction, the positioning part 241 is pushed and displaced by the X-axis adjustment rod 2611, and changes from the first deformation to the second deformation. , and the first pre-pressure increases to the second pre-pressure. Therefore, the distance that the extension arm 242 is pushed downward by the actuating part 131 when it is in the first position is greater than the distance that the extension arm 242 is pushed downward by the actuation part 131 when it is in the second position, that is, the distance between the first sound is greater than that of the second sound. distance so that the volume of the first sound is greater than the volume of the second sound. In other words, when the preload caused by deformation between the positioning portion 241 and the extension arm 242 is relatively large, the displacement of the extension arm 242 relative to the impact surface 1181 is relatively small, and therefore the generated sound is relatively small.

Referring to the drawings, the operation of adjusting the pressing feel of the button structure 20 of the present invention using the Y-axis adjusting member 262 will be described. 11A and 11B are respectively a top view and a cross-sectional view along the tangent line DD in FIG. 11A when the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A is in the first position. As shown in FIG. 11A and FIG. 11B , when the Y-axis adjustment member 262 is at the first position in the Y-axis direction, the positioning part 241 and the extension arm 242 have a first deformation relative to the spring body 243, and the extension arm 242 is relatively actuated. The movement path of the portion 131 is located at the first position in the Y-axis direction. For example, when the Y-axis adjustment member 262 is at the first position in the Y-axis direction, the extension arm 242 preferably passes through the action path when the actuating part 131 moves downward (that is, the action path is parallel to the Z-axis direction), and the key The pressing force required for the shaft 130 to move toward the base 210 and drive the moving part 131 to pass over the extension arm 242 is the first pressing force. When the Y-axis adjuster 262 is at the first position and the first pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving part 131 to move, and the extension arm 242 first moves downward and touches it downward. The surface 1311 slides to the apex 1313 , and after passing the apex 1313 , moves upwards to strike the base 210 or the cover 120 to generate a sound (eg, a first sound). In other words, when there is a first deformation between the positioning portion 241 and the extension arm 242 (that is, the elastic handle has a first Y-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 1311 is below The contact surface 1311 slides a first distance and reaches the apex 1313 , and the extension arm 242 passes over the apex 1313 later, and then breaks away from the protrusion and moves upward. It should be noted here that when the extension arm 242 reaches the apex 1313, the extension arm 242 and the impact surface of the base 10 or the cover 120 (such as the impact surface 1181 of the impact portion 118 of the base 110) have a first sounding distance, and the extension arm 242 strikes Hit the impact surface for the first sound.

12A and 12B are respectively a top view and a cross-sectional view along the tangent line DD in FIG. 12A when the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A is in the second position. As shown in Figure 12A and Figure 12B, when the Y-axis adjusting member 262 is in the second position in the Y-axis direction, the positioning part 241 and the extension arm 242 have a second deformation relative to the spring body 243, and the extension arm 242 has a second deformation relative to the actuating The movement path of the portion 131 is located at the second position in the Y-axis direction. For example, when the Y-axis adjustment member 262 is at the second position in the Y-axis direction, the extension arm 242 preferably passes through the action path when the actuating part 131 moves downward (that is, the action path is parallel to the Z-axis direction), and the key The pressing force required for the shaft 130 to move toward the base 210 and drive the moving part 131 over the extension arm 152 is the second pressing force. In this embodiment, when the Y-axis adjustment member 262 is located at the second position in the Y-axis direction, the second position of the Y-axis adjustment member 262 in the Y-axis direction may be closer to the outside of the base 210 than the first position, for example, closer to the actuation Vertex 1313 of portion 131 . In other words, the Y-axis adjusting rod 2621 moves toward the outside of the base 210 along the Y-axis direction to push the extension arm 242 outward, so that the preload between the extension arm 242 and the positioning portion 241 increases. When the Y-axis adjustment member 262 is at the second position and the second pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving part 131 to move, and the extension arm 242 first moves downward and collides downward. The surface 1311 slides to the apex 1313 , and after passing the apex 1313 , moves upwards to strike the impact surface of the base 210 or the cover 120 to generate a sound (eg, a second sound). In other words, when there is a second deformation between the positioning portion 241 and the extension arm 242 (that is, the elastic handle has a second Y-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 242 is below The contact surface 1311 slides a second distance and reaches the apex 1313 , and the extension arm 242 passes over the apex 1313 later, and then moves upwards away from the bump. In this embodiment, because the extension arm 242 is closer to the apex 1313 than the first position when the extension arm 242 is in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 242 reaches the apex 1313, the extension arm 242 and the impact surface (such as the impact surface 1181 of the impact portion 118 of the base 110) have a second sounding distance, and the extension arm 242 strikes the impact surface to produce a second sounding distance. sound.

Specifically, when the Y-axis adjusting member 262 is located at the first position or the second position in the Y-axis direction, the preload generated by the deformation of the positioning part 241 and the extension arm 242 is still in the actuating part 131 to push the extension arm 242 downward. In the range. Therefore, when a sufficient pressing force (for example, the first pressing force or the second pressing force) is applied to the key shaft 130, the extension arm 242 will first move downwards and slide along the lower contact surface 1311 under the downward thrust of the actuating part 131. Go to the apex 1313 , and after passing the apex 1313 , move upwards by the rebound force and hit the impact surface (for example, 1181 ) of the base 110 or the cover 120 to generate a sound. It should be noted here that in this embodiment, when the Y-axis adjustment member 262 moves from the first position to the second position in the Y-axis direction, the extension arm 242 is pushed and displaced by the Y-axis adjustment rod 221 to change its relative actuation The position of the action path of the part 131 makes the first deformation change into the second deformation, and the first preload increases into the second preload. Therefore, the distance that the extension arm 242 is pushed downward by the actuating part 131 when it is in the first position is greater than the distance that the extension arm 242 is pushed downward by the actuation part 131 when it is in the second position, that is, the distance between the first sound is greater than that of the second sound. distance so that the volume of the first sound is greater than the volume of the second sound. In other words, when the preload caused by deformation between the positioning portion 241 and the extension arm 242 is relatively large, the displacement of the extension arm 242 relative to the impact surface 1181 is relatively small, and therefore the generated sound is relatively small.

Moreover, when the Y-axis adjusting member 262 moves farther outside the base 210 along the Y-axis direction, the extension arm 242 is displaced more relative to the moving path of the actuating part 131 . For example, when the extension arm 242 is substantially located at the position corresponding to the apex 1313 of the actuating part 131 relative to the action path, the preload generated by the deformation between the positioning part 241 and the extension arm 242 is too large, and the key shaft 130 cannot press down the torsion spring, and then the The extension arm 242 is pushed out from the side, resulting in a frustrating feel. 13A and 13B are respectively a top view of the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A at the third position and a cross-sectional view along the tangent line DD in FIG. 13A . As shown in FIG. 13A and FIG. 13B , when the Y-axis adjusting member 262 is at the third position in the Y-axis direction, the positioning portion 241 and the extension arm 242 have a third deformation relative to the spring body 243 (that is, the handle elastic member has a third Y axis deformation), and the extension arm 242 is located at a third position in the Y-axis direction relative to the movement path of the actuating part 131 . Specifically, the third position of the Y-axis adjusting member 262 in the Y-axis direction may be closer to the outside of the base 110 than the second position, that is, substantially corresponding to the apex 1313 of the actuating portion 131 . In other words, the Y-axis adjustment lever 2621 moves further toward the outside of the base 210 along the Y-axis direction to push the extension arm 242 outward, so that the preload between the extension arm 242 and the positioning portion 241 increases, and the extension arm 242 moves in the Z-axis direction. The position substantially corresponds to the apex 1313 of the actuating part 131 . Therefore, when the Y-axis adjustment member 262 is at the third position and exerts a pressing force on the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving part 131 to push the extension arm 242 out along the Y-axis direction toward the action path, and Produce a frustrating feel. At this time, since the actuating part 131 does not press down on the extension arm 242 , the extension arm 242 only displaces laterally, but does not press down and rebound to hit the impact surface 1181 , so no sound is generated.

Moreover, when the Y-axis adjusting member 262 moves a distance along the Y-axis direction so large that the extension arm 242 deviates out of the movement path of the actuating part 131 , the key structure 20 can provide a linear feel. 14A and 14B are respectively a top view and a cross-sectional view along the tangent line DD in FIG. 14A when the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A is in the fourth position. As shown in FIG. 14A and FIG. 14B, when the Y-axis adjusting member 262 is at the fourth position in the Y-axis direction, the positioning part 241 and the extension arm 242 have a fourth deformation relative to the spring body 243 (that is, the handle elastic member has a fourth Y axis), and the extension arm 242 is located at a fourth position in the Y-axis direction relative to the movement path of the actuating part 131 , that is, a position outside the movement path. For example, the fourth position of the Y-axis adjustment member 262 in the Y-axis direction may be closer to the outside of the base 110 than the third position, that is, the Y-axis adjustment rod 2621 moves further toward the outside of the base 210 in the Y-axis direction and further outwards. Pushing the extension arm 242 increases the preload between the extension arm 242 and the positioning portion 241 , and the extension arm 242 displaces toward the outside of the base 210 along the Y-axis direction and deviates from the action path of the actuating portion 131 . Therefore, when the Y-axis adjustment member 262 is at the fourth position and exerts a pressing force on the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving part 131 to move downward without interfering with the extension arm 242, so as to generate linearity. feel.

It should be noted here that although the embodiments of FIG. 10B and FIG. 10C sequentially show that the X-axis adjustment member 261 moves in different positions toward the inside of the base 210 along the X-axis direction, the X-axis adjustment member 261 can also move toward the base 210 along the X-axis direction. The outer side moves to different positions, and the positioning part 241 can move toward the outside of the base 210 with the X-axis adjustment part 261 by virtue of the elastic recovery force of the deformation, and has a deformation corresponding to the position of the X-axis adjustment part 261 in the X-axis direction, thereby providing a corresponding pressing feel. Furthermore, although the embodiments shown in FIGS. 11A to 14B sequentially show that the Y-axis adjustment member 262 moves in different positions toward the outside of the base 210 along the Y-axis direction, the Y-axis adjustment member 262 can also move toward the inside of the base 210 along the Y-axis direction. In different positions, and the extension arm portion 242 can move toward the inside of the base 210 along with the Y-axis adjustment member 262 due to the elastic recovery force of the deformation, and has a deformation corresponding to the position of the Y-axis adjustment member 262 in the Y-axis direction, so as to be located at the corresponding position. The position of the action path of the actuating part 131 further provides a corresponding pressing feeling. Specifically, according to practical applications, the button structure 20 can selectively provide more than two kinds of pressing sensations by controlling the position of the X-axis adjustment member 261 in the X-axis direction or the position of the Y-axis adjustment member 262 in the Y-axis direction. In other words, the X-axis adjustment member 261 can move toward the inside or outside of the base 210 in the X-axis direction, so as to selectively control the position of the X-axis adjustment member 261, (1) make the deformation between the positioning part 241 and the extension arm 242 (or preload) When the key shaft 130 moves toward the base 110 and drives the actuating part 131 to move, the actuating part 131 can press down the extension arm 242, so that the extension arm 242 is displaced in the Z-axis direction and then hits the impact surface 1181. position (for example, the first position or the second position in the direction of the X-axis), so as to provide a variety of hand feeling with different pressing forces, and to emit sounds with different volumes. Moreover, the Y-axis adjustment member 262 can move toward the outside or inside of the base 210 in the Y-axis direction, so as to selectively control the position of the Y-axis adjustment member 262, (1) make the extension arm 242 pass through the movement portion 131 Action path, and the deformation (or preload) between the positioning part 241 and the extension arm 242 when the key shaft 130 moves toward the base 210 and drives the actuation part 131 to move, the actuation part 131 can press down the extension arm 242 to make the extension The arm 242 produces Z-axis direction displacement and then strikes the position of the impact surface 1181 (such as the first position in the Y-axis direction, the second position, or any convenient position before reaching the third position), (2) the extension arm 242 substantially corresponds to the apex 1313 of the actuating part 131, and when the deformation (or preload) between the positioning part 241 and the extension arm 242 moves toward the base 110 and drives the actuating part 131 to move, the actuating part 131 moves toward Push out the position of the extension arm 242 outside the path (for example, the third position in the Y-axis direction), so as to provide a silent feeling of frustration; or (3) make the extension arm 242 located outside the action path, when the key shaft 130 faces the base When 110 moves and drives the actuating part 131 to move, the actuating part 131 will not interfere with the extension arm 242 (for example, the fourth position in the X-axis direction), and a silent linear feel can be provided.

It should be noted here that the button structure 20 of the present invention can achieve the desired pressing feel only through the adjustment of the X-axis adjustment member 261 or the Y-axis adjustment member 262, or can also be adjusted by the X-axis adjustment member 261 and the Y-axis adjustment member. 262 fit and adjust to achieve the desired pressing feel. In other words, in other embodiments, the button structure 20 of the present invention may only include the X-axis adjustment member 261 or the Y-axis adjustment member 262 , and is not limited to including both the X-axis adjustment member 261 and the Y-axis adjustment member 262 as shown in the embodiment. Furthermore, when adjusted by the X-axis adjustment member 261, the first position or the second position of the extension arm 242 may be the same as or different from the first position where the extension arm 242 is located when adjusted by the Y-axis adjustment member 262. first position or second position. Therefore, when the X-axis adjusting member 261 is moved to the first position or the second position, the pressing force required for the key shaft 130 to move toward the base 210 and drive the moving part 131 over the extension arm 242 may be the same or different from that by When the Y-axis adjustment member 262 is moved to the first position or the second position, the key shaft 130 moves toward the base 210 and drives the moving part 131 to pass the required pressing force of the extension arm 242 .

In addition, when multiple key structures 10, 20 of the present invention are integrated into the keyboard device, the adjustment parts of each key structure can be integrated into a single component by integrating the connecting parts of the adjustment parts of each key structure, so as to facilitate the adjustment of multiple key structures.

Moreover, the keyboard device 1 includes a control member 15 to control the movement of the frame-shaped connecting portion or the sheet-shaped connecting portion, and further control the movement of the adjusting rod 161 to adjust the pressing feel provided by the plurality of key structures 10 . In this embodiment, the control member 15 can be a push rod linked with the connecting part, and can be controlled manually or automatically.

It should be noted here that when multiple key structures 20 are integrated into the keyboard device, the connection parts 2612 of the X-axis adjustment parts 261 of each key structure 20 can be connected to each other to form a frame-shaped connection part or a sheet-shaped connection part, and each key structure The connecting portion 2622 of the Y-axis adjustment member 262 of 20 can be connected to each other to form another frame-shaped connection portion or a sheet-shaped connection portion, and the keyboard device can include an X-axis control member and a Y-axis control member to control the X-axis adjustment member 261 and the Y-axis control member respectively. Y-axis adjusting member 262, but not limited thereto. In other embodiments, depending on the actual application, when the plurality of key structures 20 only have the X-axis adjustment member 261 or the Y-axis adjustment member 262 and are integrated into the keyboard device, the keyboard device may only include the X-axis control member or the Y-axis control member, To control the X-axis adjustment member 261 or the Y-axis adjustment member 262 correspondingly.

The button structure of the present invention can change the deformation of the handle elastic part through the adjusting part, and then can change the pressing feel of the button structure. Moreover, the button structure of the present invention can change the position of the extension arm relative to the actuating part by changing the moving position of the adjustment member, so as to selectively provide different pressing forces, frustration, linearity and other pressing sensations.
