The user presses the keycap 14 by touching the keycap cover 146 . In practice, the structural plate 142 and the keycap cover 146 can be made of different materials, which can increase the overall structural design flexibility of the keycap 14 and help to take into account both The rigidity and thinning design of the overall structure of the keycap 14 . For example, but not limited to, the structural plate 142 is a metal stamping part, and the keycap cover 146 is a plastic injection molding part; the latter is beneficial to the design of the appearance and touch of the keycap 14 . In addition, in practice, the connecting portions 144a and 144b may include plastic, resin or other polymer materials, but the molding method is not limited to an injection molding, such as being combined with the structural plate 142 by embedding.

Please also refer to Figures 4 to 8. The structural plate 142 has a bonding structure 1422 . The joint portion 144a is fixed and fitted with the joint structure 1422 to be combined with the structural plate 142 . The combining structure 1422 includes a protruding portion 1422a, two through holes 1422b, 1422c, a side hole 1422d, a combining hole 1422e, and a cantilever plate 1422f. The convex portion 1422a is formed on one side of the structural plate 142 (such as the upward side in Figs. 4, 5, 7, and 8) and a groove 1422g is formed on the other side of the structural plate 142 (such as the side in Figs. 4, 5, 7, and 8). 8); that is, in Figures 4, 5, 7, and 8, the convex portion 1422a protrudes above the structural plate 142, and the groove 1422g opens toward the bottom of the structural plate 142. The through holes 1422b, 1422c and the side holes 1422d all pass through the convex portion 1422a; wherein, the through holes 1422b, 1422c pass through the top surface of the convex portion 1422a (that is, where the lead labeled "1422a" in the fifth figure refers to) (that is, the through holes 1422b, 1422c are formed On the top surface of the convex portion 1422a), the side hole 1422d penetrates through the side wall 1422a' of the convex portion 1422a, a part of the top surface of the convex portion 1422a and a part of the structural plate 142 (that is, the side hole 1422d is partially formed on the top surface of the convex portion 1422a and partially formed in The side wall 1422a' is partially formed on the body of the structural board 142). The coupling hole 1422e is disposed adjacent to the convex portion 1422a and communicates with the groove 1422g. The cantilever plate 1422f is bent and extended from the edge of the coupling hole 1422e (ie, it is bent and extended upward in the fourth, fifth, and eighth figures). The coupling hole 1422e between the convex portion 1422a and the cantilever plate 1422f. The joint portion 144a is filled with the through holes 1422b, 1422c, the side hole 1422d, the joint hole 1422e and the groove 1422g, and covers the convex portion 1422a and the cantilever plate 1422f. From the perspectives of Figs. 4, 5, 7, and 8, the joint portion 144a is simultaneously formed on the upper and lower sides of the convex portion 1422a (or logically formed on the upper and lower sides of the structural plate 142). The through holes 1422b, 1422c, the side holes 1422d and the bonding hole 1422e are all helpful for forming the bonding portion 144a (for example, to increase the efficiency of filling the plastic during injection, avoiding the situation of unsaturated mold), and also help the bonding portion 144a to cover the convex portion 1422a (thereby increasing the bond strength between the two). Among them, through the through holes 1422b, 1422c and The side hole 1422d can increase the cross-sectional area of the joint portion 144a passing through the convex portion 1422a. The upper fin 1442 (the part located above the convex portion 1422a) and the lower fin 1444 (the portion located below the convex portion 1422a) of the joint portion 144a The part located in the groove 1422g) can increase the interconnected area through the through holes 1422b, 1422c, the side holes 1422d and the coupling hole 1422e (wherein the side hole 1422d passing through the side wall 1422a' is in principle larger than the through hole 1422c passing through the top surface of the convex portion 1422a. The upper fins 1442 and the lower fins 1444 can be provided with a larger structural connection section), which improves the clamping effect of the upper fins 1442 and the lower fins 1444 on the convex portion 1422a, which is helpful for the joint portion 144a and the structural plate 142 ( Or the bonding strength between the convex portions 1422a) can also improve the structural stability and tensile strength of the bracket connecting portion 14a.

In the first embodiment, the joint portion 144a independently forms the bracket connecting portion 14a and a gimbal connecting portion 14c. The connecting portion 144a includes a first hook arm 14d corresponding to the bracket connecting portion 14a. The first hook arm 14d is formed on the protruding portion 1422a to form the bracket connecting portion 14a. The first hook arm 14d is L-shaped and forms a sliding groove 14e. The first key support 162 is slidably disposed in the sliding groove 14e through the first keycap connecting portion 1622 (a partial outline of which is shown in dotted lines in FIG. 4 ). It is slidably connected to the bracket connecting portion 14a. The through hole 1422b is aligned with the bracket connecting portion 14a; in other words, the through hole 1422b overlaps with the projection of the bracket connecting portion 14a in the vertical direction. On the other hand, the vertical projection of the first hook arm 14d falls within the range of the top surface of the convex portion 1422a (the outline of the first hook arm 14d on the convex portion 1422a is shown by a dotted line in FIG. 5). This structural configuration helps to enhance the structural bonding strength between the joint portion 144a (especially the bracket connecting portion 14a) and the convex portion 1422a, thereby enhancing the structural stability and tensile strength of the bracket connecting portion 14a (for example, in the first 4 and 5, resist the ability of the first button bracket 162 to pull up the first hook arm 14d). The projections of the first hook arm 14d and the through hole 1422b in the vertical direction overlap, and the through hole 1422c and the side hole 1422d are located on the front and rear sides of the bracket connecting portion 14a, which can effectively lift the bracket connecting portion 14a (or the first hook arm 14d). tensile strength. In addition, in the first embodiment, although the joint portion 144a independently forms the bracket connecting portion 14a, in practice, the joint portion 144a and the convex portion 1422a can jointly form the bracket connecting portion 14a, for example, the top surface of the convex portion 1422a can be used as the Bottom of chute 14e.

In addition, the connecting portion 144a corresponding to the gimbal connecting portion 14c further includes a first clamping arm 14f and a second clamping arm 14g. The first clamping arm 14f is formed on the convex portion 1422a, the second clamping arm 14g covers the cantilever plate 1422f, and the first clamping arm 14f and the second clamping arm 14g are used to form the gimbal connecting portion 14c. The two opposite inner concave wall surfaces of the first clamping arm 14f and the second clamping arm 14g together define an axial groove 14h for the balance bracket 15 to pass through. The projections of the first gripping arm 14f and the second gripping arm 14g (of the gimbal connecting portion 14c) in the vertical direction respectively overlap with the through hole 1422c and the cantilever plate 1422f (the first gripping arm is represented by a dashed line in FIG. 5 ) 14f and the contours of the second clamping arm 14g on the convex portion 1422a and the cantilever plate 1422f), both of which can effectively improve the tensile strength of the gimbal connecting portion 14c (or the first clamping arm 14f and the second clamping arm 14g). Strength (eg, the ability of the balance support to pull up the first gripping arm 14f and the second gripping arm 14g in the viewing angles of Figures 4 and 5). This structural configuration helps to enhance the bonding strength between the gimbal connecting portion 14c and the connecting structure 1422, thereby improving the structural stability and tensile strength of the gimbal connecting portion 14c. In addition, in the perspectives of Figs. 4 and 5, the bottom of the holding space (ie, the shaft slot 14h) of the gimbal connecting portion 14c for the gimbal bracket 15 is slightly higher than the structural plate 142, and the structural plate 142 allows the gimbal 142 to pass through the coupling hole 1422e. space to increase the structural strength of the gimbal connecting portion 14c. The coupling hole 1422e communicates with the groove 1422g, which contributes to the coupling strength between the gimbal connecting portion 14c and the convex portion 1422a. Among them, as shown in FIG. 4, the convex portion 1422a, the coupling hole 1422e and the cantilever plate 1422f are arranged along a first direction D1 (represented by a double-headed arrow in the figure), and the coupling hole 1422e is arranged along a second direction D2 (indicated by a double-headed arrow). The head arrow is shown in the figure, and its width 1422e' (or aperture) perpendicular to the first direction D1) is larger than the width 1422a" of the convex portion 1422a (the portion adjacent to the coupling hole 1422e) along the second direction D2 and larger than the cantilever plate The width 1422f' of 1422f along the second direction D2. The portion of the coupling hole 1422e adjacent to the convex portion 1422a has a larger size, which is conducive to the application of millimeter-level precision machining and precision plastic processing. When machining the structural plate 142, The larger coupling hole 1422e is convenient for cutting out the cantilever plate 1422f and the perforation 1422c of a specific shape and position, and the larger coupling hole 1422e is also convenient for molding the convex part 1422a of a specific size/shape in the position corresponding to the cantilever plate 1422f. During injection molding, the plastic It is convenient to completely fill the space of the groove 1422g under the convex portion 1422a, which can avoid the situation of unsaturated mold. In practice, although the cantilever plate 1422f is wider and larger, the pull-out force will increase, but this will not allow It is easy for the plastic to fill the gimbal connecting portion 14c covering the cantilever plate 1422f, and the gimbal connecting portion 14c is too bulky and takes up unnecessary space.

In the first embodiment, the cantilever plate 1422f has a holding structure 1422h, which can increase the bonding strength between the joint portion 144a (or the gimbal connecting portion 14c) and the cantilever plate 1422f (or increase the resistance to the separation of the joint portion 144a and the cantilever plate 1422f). Ability). In the first embodiment, the holding structure 1422h is a necked portion of the cantilever plate 1422f, located between the fixed end and the free end of the cantilever plate 1422f. The necked portion can increase the contact area between the joint portion 144a and the cantilever plate 1422f and the degree of structural interference with the joint portion 144a. The cantilever plate 1422f generally has a T-shaped structure as a whole, and the difference in width between the head and the body is used as the structural basis of the necking portion, but it is not limited in practice. For example, the cantilever plate 1422f can be replaced by a cantilever plate 1423a with a substantially fixed width, as shown in FIG. 9; wherein a notch is formed between the fixed end and the free end of the cantilever plate 1423a, which can also be used as the necking portion 1423b (shown in dashed box in the figure). For another example, the cantilever plate 1422f can be implemented by a cantilever plate 1423c with a gradual width, as shown in FIG. 10; wherein, the width of the cantilever plate 1423a increases gradually from the fixed end to the free end. At this time, the two sides of the cantilever plate 1423c Logically, it can be used as the necking portion 1423d (shown as a dashed box in the figure). In addition, the retaining structure 1422h can also be realized by other structures in practice. For example, as shown in FIG. 11, through holes 1423f (or blind holes, or serrations formed on both sides of the cantilever plate 1423e) are formed on the cantilever plate 1423e. like structure). For another example, the holding structure 1422h can also be realized by a combination of the aforementioned structures. For example, the cantilever plate 1423g shown in FIG. 12, the holding structure (shown in a dotted frame in the figure) includes a necked portion on one side of the cantilever plate 1423g And the oblique edge (or the side edge of the cantilever plate 1423g whose width is gradually changed) located on the other side of the cantilever plate 1423g is used as a holding structure. The cantilever plates 1423a , 1423c , 1423e , and 1423g of each of the aforementioned modifications can increase the bonding strength with the bonding portion 144 a through the degree of structural interference with the bonding portion 144 a.

In addition, in the first embodiment, the cantilever plate 1422f itself is a flat plate structure, that is, the plate body 1420 of the structural plate 142 is bent only once and then extends upward. When the cantilever plate 1422f is pulled upward by the second clamping arm 14g, the cantilever plate 1422f itself will only bear axial stress (ie, parallel to the extending direction) in principle, but no bending stress. The upward pulling force of the plate 1422f has a The moment generated by the fixed end (ie, from the bending place of the plate body 1420 ) is also small, so the bending stress on the fixed end of the cantilever plate 1422f is also small. This structural feature enables the cantilever plate 1422f to generate less deformation when it is subjected to an upward pulling force, which helps to maintain the structural stability of the cantilever plate 1422f itself and the joint portion 144a (or the gimbal joint portion 14c).

In addition, as shown in FIG. 4 and FIG. 5, in the first embodiment, the gimbal connecting portion 14c is close to the bracket connecting portion 14a, so the two structures are integrated and implemented by a single joint portion 144a. The structural plate 142 (or its plate body 1420 ) has one side 142a, and the gimbal connecting portion 14c is located between the bracket connecting portion 14a and the side 142a. The combination structure 1422 is close to the side edge 142a, and the space for the structure board 142 for the combination structure 1422 to be arranged is limited. The cantilever plate 1422f is located between the protruding portion 1422a and the side edge 142a, which can take into account structural combination and space utilization. In practice, if space permits, the gimbal connecting portion 14c and the bracket connecting portion 14a can also be structurally separated and formed individually. In addition, with the permission of the structure space, the structure of the coupling structure 1422 corresponding to the gimbal connecting portion 14c (including part of the convex portion 1422a, the through hole 1422c, the coupling hole 1422e, the cantilever plate 1422f) can also be applied to the coupling structure 1422 corresponding to the bracket connecting portion 14a structure; and vice versa.

See figures 2, 3, 13 to 15. In the first embodiment, the structural plate 142 has another coupling structure 1424 corresponding to the bracket connecting portion 14b. The combining structure 1424 includes a convex portion 1424a, a through hole 1424b, and two side holes 1424c and 1424d. The convex portion 1424a is formed on one side of the structural plate 142 (such as the upward side in Figures 13 to 15) and a groove 1424e is formed on the other side of the structural plate 142 (such as the downward side in Figures 13 to 15). ); that is, in Figures 13 to 15, the protruding portion 1424a protrudes toward the top of the structural plate 142, and the groove 1424e opens toward the bottom of the structural plate 142. The through-hole 1424b and the side holes 1424c and 1424d all penetrate through the convex portion 1424a; wherein, the through-hole 1424b penetrates through the top surface of the convex portion 1424a (that is, where the lead labeled "1424a" in Fig. 14 refers to) (that is, the through-hole 1424b is formed in the convex portion 1422a) The side holes 1424c and 1424d penetrate through the side walls 1424a' of the opposite sides of the convex portion 1424a, a part of the top surface of the convex portion 1424a and a part of the structural plate 142 (that is, the side holes 1424c and 1424d are partially formed on the top of the convex portion 1424a). surface, part formed on the side wall 1424a' and part formed on the body of the structural board 142), the through hole 1424b is located between the two side holes 1424c and 1424d. The joint portion 144b is filled with the through holes 1424b, The side holes 1424c, 1424d and the groove 1424e cover the convex portion 1424a. From the perspective of FIGS. 13 to 15 , the joint portions 144b are simultaneously formed on the upper and lower sides of the protruding portion 1424a (or logically formed on the upper and lower sides of the structural plate 142 ). The through holes 1424b and the side holes 1424c and 1424d are both helpful for the forming of the joint portion 144b (for example, increasing the efficiency of filling the plastic during injection, avoiding the situation of unsaturated mold), and also helping the joint portion 144b to cover the convex portion 1424a (and thus increase the bond strength between the two). Wherein, through the through hole 1424b and the side holes 1424c, 1424d, the cross-sectional area of the joint portion 144b passing through the convex portion 1424a can be increased. The part below the convex part 1424a, or the part located in the groove 1424e) can increase the interconnected area through the through hole 1424b and the side holes 1424c, 1424d, and improve the clamping of the convex part 1424a by the upper fin 1446 and the lower fin 1448 As a result, the bonding strength between the bonding portion 144b and the structural plate 142 (or the protruding portion 1424a ) is facilitated, and the structural stability and tensile strength of the bracket connecting portion 14b can also be improved.

In the first embodiment, the joint portion 144b independently forms the bracket connecting portion 14b. The joint portion 144b includes a first hook arm 14i and a second hook arm 14j. The first hook arm 14i and the second hook arm 14j are formed on the top surface of the protruding portion 1424a to form the bracket connecting portion 14b. The two opposite concave wall surfaces of the first hook arm 14i and the second hook arm 14j together define a shaft groove 14k, and the second key bracket 164 passes through the second keycap connecting portion 1642 (a partial outline of which is shown in dotted lines in FIG. 13 ) It is rotatably arranged in the shaft groove 14k to be rotatably connected with the bracket connecting portion 14b. The through hole 1424b is aligned with the bracket connecting portion 14b; in other words, the through hole 1424b overlaps with the projection of the bracket connecting portion 14b in the vertical direction. On the other hand, the vertical projections of the first hook arm 14i and the second hook arm 14j both fall within the range of the top surface of the convex portion 1424a (the first hook arm 14i and the second hook arm are represented by dotted lines in FIG. 14 ) 14j on the convex portion 1424a profile). This structural configuration helps to improve the bonding strength between the joint portion 144b (especially the bracket connection portion 14b) and the convex portion 1424a, thereby improving the structural stability and tensile strength of the bracket connection portion 14b (for example, as shown in FIGS. 13 and 14 ). From the perspective of the figure, resist the ability of the second key bracket 164 to pull the first hook arm 14i and the second hook arm 14j upward). The first hook arm 14i and the second hook arm 14j overlap with the vertical projections of the side holes 1424c and 1424d respectively, which can effectively lift the bracket connecting portion 14b (or the first hook arm 14i and the The tensile strength of the hook arm 14j). In addition, in the first embodiment, although the joint portion 144b independently forms the shaft groove 14k of the bracket connecting portion 14b, in practice, the joint portion 144b and the convex portion 1424a can jointly form the bracket connecting portion 14b, for example, the convex portion 1424a can be used instead. The top surface of the shaft serves as the bottom of the shaft groove 14k.

In the first embodiment, the combining structure 1422 is used for combining the partial structure of the corresponding bracket connecting portion 14a (including the first hook arm 14d) and the gimbal connecting portion 14c, and the combining structure 1424 is used for combining the corresponding partial structure of the bracket connecting portion 14b. The structures are not the same, but the implementation is not limited to this. In addition, the combination structure between the structural plate 142 and the bracket connecting portions 14a and 14b and the gimbal connecting portion 14c is not limited to the foregoing embodiments. For example, as shown in FIG. 16 , in a second embodiment, the coupling structure 1424 ′ corresponding to the bracket connecting portion 14 b includes a through hole 1424 f , a cantilever plate 1424 g and a convex bridge portion 1424 h in addition to the convex portion 1424 a . The through hole 1424f, the protruding bridge portion 1424h and the cantilever plate 1424g are all located on the top surface of the protruding portion 1424a. The cantilever plate 1424g is bent and extended from the edge of the through hole 1424f, and the convex bridge portion 1424h is connected across the two sides of the through hole 1424f relative to the cantilever plate 1424g (that is, the projection of the through hole 1424f in the vertical direction is divided into two parts, or the convex bridge portion 1424h divides the through hole 1424f to form a hole portion 1424i on one side, which and the cantilever plate 1424g are located on both sides of the convex bridge portion 1424h; on the other hand, in terms of structural logic, the through hole 1424f can also be regarded as located in the convex bridge portion 1424h and the cantilever plate 1424g). The joint portion 144b is filled with the through hole 1424f and the groove 1424e and covers the cantilever plate 1424g and the convex bridge portion 1424h (wherein, the first hook arm 14i and the second hook arm 14j respectively cover the cantilever plate 1424g and the convex bridge portion 1424h to form a The bracket connecting portion 14b. This structural configuration helps to enhance the bonding strength between the first and second hook arms 14i, 14j and the combining structure 1424', thereby enhancing the structural stability of the bracket connecting portion 14b.

In addition, in the second embodiment, the cantilever plate 1424g is similar in structure to the cantilever plate 1422f of the coupling structure 1422 in the first embodiment, and also has a holding structure 1424j, which can increase the corresponding first hook arm 14i and cantilever plate 1424g bond strength. For other descriptions of the holding structure 1424j, please refer to the foregoing descriptions of the cantilever plate 1422f and its changes, which will not be repeated. In addition, in the second embodiment, the connection interface between the protruding bridge portion 1424h and the through hole 1424f (represented by dotted lines in FIG. 16 ) is arc-shaped, which can increase the inertia moment of the protruding bridge portion 1424h and increase the resistance of the protruding bridge portion 1424h Ability to be pulled by the bracket connection 14b. In addition, in the second In the embodiment, the combination structure 1424 ′ is not limited to disposing the cantilever plate 1424g and the protruding bridge portion 1424h at the same time. For example, in the combination structure 1424', the cantilever plate 1424g is changed to a convex bridge portion, or the convex bridge portion 1424h is changed to a cantilever plate. For another example, in the combination structure 1424 ′, the cantilever plate 1424g and the protruding bridge portion 1424h are selectively reserved, and structures such as the through holes 1424c and 1424d in the combination structure 1424 can be added.

In addition, based on the foregoing, the combining structures 1422 , 1424 , and 1424 ′ are used to combine the corresponding bracket connecting portion 14 a (including the first hook arm 14 d ), the bracket connecting portion 14 b (including the first and second hook arms 14 i , 14 j ) and the gimbal. Description of the partial structure of the connecting portion 14c (including the first and second clamping arms 14f, 14g), in practice, structural features such as convex portions, cantilever plates, coupling holes, perforations, etc., or combinations thereof can be used to realize the bracket connection The combination between the parts 14a, 14b and the gimbal connecting part 14c and the structural plate 142 will not be described in detail. For example, in the first embodiment, as shown in FIG. 5, the coupling structure 1422 can be provided with a cantilever plate at the edge of the through hole 1422b, and the bracket connecting portion 14a covers the cantilever plate. This configuration can enhance the structure of the bracket connecting portion 14a. stability.

See Figures 2, 3, 17, 18. In the first embodiment, the keycap 14 includes a pressing portion 148 corresponding to the elastic restoring member 22 (a partial outline of which is shown in dotted lines in FIG. 18 ). The structural plate 142 includes a second combining hole 1426 and two second protruding portions 1428 . The two second protruding portions 1428 protrude from opposite sides of the second combining hole 1426 . The pressing portion 148 fills the second combining hole 1426 and covers the two second protruding portions 1428, so as to be fixed on the structural board 142; in practice, the pressing portion 148 can also be fixed on the structural board 142 through other combining structures , without further elaboration. The pressing portion 148 has a pre-compression area 1482 , which faces the elastic restoring member 22 and can provide the elastic restoring member 22 with a preset pressure (ie abuts against the top 22 a of the elastic restoring member 22 through the pre-compressing area 1482 ). When the keycap 14 is pressed, the elastic restoring member 22 is pressed through the pre-pressing area 1482 . In the first embodiment, the pre-pressed area 1482 is the bottom of a groove. The depth 1482a of the pre-pressed region 1482 (ie, the depth of the groove) may be determined according to product specifications (eg, pressure feedback force requirements) or product manufacturing requirements (eg, differences in mechanical properties of elastic restoring elements 22 in different batches), for example Thereby, the elastic deformation amount of the elastic restoring member 22 is controlled to provide the user with a desired pressing feeling. In practice, the pressing portion 148 can be fixed on the structural plate 142 through, but not limited to, the buried injection, which is beneficial to adjust the depth 1482a of the pre-pressed region 1482 at a lower cost. The entire keycap 14 structure needs to be modified. In addition, the vertical projection of the top 22a of the elastic restoring member 22 falls within the vertical projection of the second combining hole 1426, so the second combining hole 1426 has a structure avoidance function, so that the pre-compression area 1482 is located in the second combining hole 1426. In the hole 1426, the adjustment range of the depth 1482a of the pre-pressed area 1482 can be increased. In addition, in practice, the pre-compression area 1482 can also be implemented by a rib structure 1482b (shown in dotted lines in Figures 2, 17, and 18). The rib structure 1482b can be, but not limited to, a radial shape. At this time, the top of the rib structure 1482b pushes against the top 22a of the elastic restoring member 22 . Similarly, modifying the protruding height of the rib structure 1482b (or the thickness of the rib structure 1482b ) can produce the same effect as the aforementioned modification of the depth 1482a (eg, adjusting the pressing feel), which will not be described in detail.

In the first embodiment, as shown in FIG. 2 , the structural plate 142 includes a plate body 1420 , two sidewall plates 1430 extending parallel to and perpendicular to the plate body 1420 , and a reinforcing rib structure protruding from the plate body 1420 . 1432 , all of which help to improve the rigidity of the structural panel 142 . The plate body 1420 is in the shape of a long and narrow rectangle, and the side wall plate 1430 is located on the long side of the plate body 1420 (eg, the side 142a, corresponding to the long side 140a of the keycap 14). In principle, the effect of the side wall plate 1430 disposed on the long side of the plate body 1420 on the rigidity of the lifting structural plate 142 is greater than that disposed on the short side of the plate body 1420 . In addition, the first lifting mechanism 16 and the second lifting mechanism 18 are arranged in the longitudinal direction of the keycap 14 (ie, in the direction parallel to the side 140 a ), and the two side wall plates 1430 correspond to the long side 140 a of the keycap 14 (also corresponding to the two long sides of the keycap cover 146 and the two long sides of the structural board 142 body 1420 ), the two sidewall boards 1430 cover the keycap cover 146 and the structural board 142 with weaker rigidity in the longitudinal direction respectively. Therefore, the rigidity of the keycap cover 146 and the structural plate 142 can be effectively strengthened, so as to restrain or eliminate the deformation caused by the local driving force of the first lifting mechanism 16 and the second lifting mechanism 18 and the balance bracket 15 , so that the first lifting mechanism 16 , the second lifting mechanism 18 and the balance bracket 15 can locally and balancedly transmit the driving force through the keycap cover 146 and the structural plate 142 , so that the keycap cover 146 and the structural plate 142 as a whole remains level when moving up and down. In addition, in practice, if the structural plate 142 can already provide sufficient rigidity, the keycap cover 146 may also be omitted; at this time, the appearance of the keycap can also be achieved by other means, such as forming a coating layer on the structural plate 142 .

In addition, in the first embodiment, the keycap 14 further includes a reinforcing plate 141 , which is attached to the structural plate 142 and also helps to improve the rigidity of the structural plate 142 . In practice, if the rigidity of the structural plate 142 meets the requirements, the reinforcing plate 141 can also be omitted. In addition, as shown in FIG. 2 and FIG. 19, the keycap 14 includes a coupling portion 144c, the structural plate 142 correspondingly includes a coupling structure 1434, and the coupling portion 144c and the coupling structure 1434 are fixedly fitted with each other to form a gimbal connection part 14c. The coupling structure 1434 includes a coupling hole 1434a, a convex portion 1434b and a cantilever plate 1434c. The protrusion protrudes from one side of the structural plate (eg, the upward side in FIG. 19 ) and forms a groove 1434d on the other side of the structural plate 142 (eg, the downward side in FIG. 19 ). The coupling hole 1434a is disposed adjacent to the convex portion 1434b and communicates with the groove 1434d, and the coupling hole 1434a is located between the convex portion 1434b and the cantilever plate 1434c. The coupling portion 144c is filled with the coupling hole 1434a and the groove 1434d, and covers the convex portion 1434b and the cantilever plate 1434c; wherein, the coupling portion 144c includes first and second clamping arms for forming a gimbal connecting portion 14c, which are respectively formed The cantilever plate 1434c is covered on the convex portion 1434b. In addition, the convex portion 1434b, the coupling hole 1434a, and the cantilever plate 1434c are arranged along the first direction D1, and the coupling hole 1434a is located between the convex portion 1434b and the cantilever plate 1434c. The width 1434a' (or aperture) of the coupling hole 1434a along the second direction D2 is greater than the width 1434b' of the convex portion 1434b along the second direction D2 and greater than the width 1434c' of the cantilever plate 1434c along the second direction D2. In structural logic, the coupling structure 1434 is similar to a part of the structure of the coupling structure 1422 (ie, corresponding to the structure of the gimbal connecting portion 14c in FIGS. 4 and 5). For other descriptions of the coupling structure 1434 and the coupling portion 144c, please refer to the above related descriptions about the coupling structure 142, the coupling portion 144a and their changes, and will not be repeated. In addition, regarding the combination of the other gimbal connecting portions 14c in the keycap 14 and the structural plate 142, please refer to the above-mentioned description of the combination of the connecting portions 144a, 144c and the structural plate 142, and will not be repeated. In addition, the bonding relationship between the bonding portion 144c and the structural plate 142 (via the bonding structure 1434 ) can also be applied to the bonding portion 144a (corresponding to the part of the bracket connecting portion 14a ) and the bonding portion 144b and the structural plate 142 . For example, from a structural logic point of view, the first and second clamping arms (or appropriately modified) in the joint 144c can be regarded as the first and second hook arms 14i, 14j of the joint 144b (for The bracket connecting portion 14b) is formed; in other words, the bonding structure 1434 may replace the bonding structure 1424 for the bonding portion 144b to be bonded to the structural plate 142.

In addition, in the first embodiment, as shown in FIG. 3 , the joint parts 144 a , 144 b and 144 c are all coplanar with the top surface 142 b of the structural board 142 , which can increase the bonding area between the keycap cover 146 and the structural board 142 ; but not limited to this in practice. In practice, the joint parts 144a, 144b, 144c can protrude from the top surface 142b of the structural plate 142 and extend on the top surface 142b, which can increase the joint strength between the joint parts 144a, 144b, 144c and the structural plate 142 (for example, in Section 142). 7 and 8, the lower flap 1444 is modified to protrude from the top surface 142b and cover part of the top surface 142b with dotted lines). At this time, the keycap cover 146 can form an escape space on its bottom surface 146a, corresponding to the joint parts 144a, 144b, 144c (or the part protruding from the top surface 142b), so that the keycap cover 146 can still be effectively attached to the structural board 142 on the top surface 142b without structural interference with the joints 144a, 144b, 144c. Or, the aforementioned avoidance space matches the protruding outline of the joint portions 144a, 144b, 144c, so that the inner wall surface of the avoidance space also fits with the joint portions 144a, 144b, 144c.

In addition, in the first embodiment, the first lifting mechanism 16 is implemented by a scissor leg bracket, but the implementation is not limited to this. For example, the first lifting mechanism 16 is implemented as a V-shaped butterfly foot bracket or an inverted V-shaped bat bracket, and the bracket connecting portions 14a and 14b are implemented with suitable structures correspondingly, which will not be described in detail. In addition, in the first embodiment, the key structure 1 is a blank key and two lifting mechanisms 16 and 18 are used to support the keycap 14. In practice, more lifting mechanisms can be used according to the actual structural requirements. Arranged in a single row is limited. In addition, in practice, the key structure 1 can also be applied to single key (or square key), multiple key (or long key) or other geometric outline key structures through appropriate structural modification. For example, see Figures 20 and 21. According to a third embodiment, a key structure 3 is a single key, which includes a base 32 , a key cap 34 , a lifting mechanism 36 , a switch 38 and an elastic reset member 40 . The keycap 34 is disposed on the base 32 , and the lift mechanism 36 is connected between the keycap 34 and the base 32 , so that the keycap 34 can move vertically (or move up and down) relative to the base 32 via the lift mechanism 36 . A switch 38 (represented in the figure as a hatched circle; such as, but not limited to, implemented with a thin film circuit board) is disposed below the keycap 34 . The elastic reset member 40 is disposed between the base 32 and the keycap 34 corresponding to the switch 38 , and between the keycap 34 and the switch 38 . The keycap 34 can be depressed to squeeze the resilient return 40 downward to trigger the switch 38 . Button structure 3 is similar in structure and logic to button structure 1. For other descriptions of the components, in addition to the following descriptions, please refer to the relevant descriptions of the key structure 1 and its modifications, and will not be repeated.

In the third embodiment, the key cap 34 includes a structural plate 342 , two joint portions 344 a and 344 b and a key cap cover 346 . The structural plate 342 has two bonding structures 3422 and 3424 . The coupling parts 344a and 344b are fixed and fitted to each other through the coupling structures 3422 and 3424 respectively, so as to be combined with the structural plate 142 . The keycap cover 346 is fixed to the structural plate 342 for the user to contact and press. The joint parts 344a and 344b respectively independently form the bracket connecting parts 34a and 34b. The lifting mechanism 36 includes a first key support 362 and a second key support 364 pivotally connected to each other, both of which are connected between the key cap 34 and the base 32 . The first key bracket 362 is connected to the bracket connecting portion 34 a of the key cap 34 , and the second key bracket 364 is connected to the bracket connecting portion 34 b of the key cap 34 . The coupling structure 3422 includes a coupling hole 3422a and two convex portions 3422b disposed on opposite sides of the coupling hole 3422a. The coupling portion 344a fills the coupling hole 3422a and covers the two convex portions 3422b (and fills the grooves formed therein) for fixing onto the structural plate 342. The combining structure 3424 includes a convex portion 3424a, a through hole 3424b, and side holes 3424c and 3424d. The convex portion 3424a is on one side of the structural plate 342 (such as the upward side in Fig. 21) and a groove 3424e is formed on the other side of the structural plate 342 (such as the downward side in Fig. 21); that is, , in FIG. 21 , the convex portion 3424a protrudes toward the upper side of the structural plate 342 , and the opening of the groove 3424e is toward the bottom of the structural plate 342 . The through hole 3424b and the side holes 3424c and 3424d all penetrate through the convex portion 3424a. The coupling portion 344b is filled with the coupling hole 3422a, the through hole 3424b, the side holes 3424c, 3424d and the groove 3424e, and covers the convex portion 3424a, so as to be fixed on the structural plate 342. In structural logic, the combination of the combination part 344b and the combination structure 3424 is equivalent to the combination of the combination part 144b and the combination structure 1424. Therefore, for other explanations about the combination of the combination part 344b and the combination structure 3424, please refer to the combination of the combination part 144b and the combination structure 3424. The related description of the combination of the combination structure 1424 and its modification examples will not be repeated. In practice, the combination of the combination parts 344a, 344b and the structural plate 342 can also be implemented with reference to the combination of the combination parts 144a, 144b, 144c and the structure plate 142 in the key structure 1 and its modifications, which will not be repeated. Similarly, the combination of the joint parts 344a, 344b and the structural plate 342 can also be applied to the combination of the joint parts 144a, 144b, 144c and the structural plate 142, which will not be described in detail.

In addition, in the third embodiment, the first button bracket 362 and the second button bracket 364 are both annular, so that the elastic reset member 40 can be disposed through the first button bracket 362 and the second button bracket 364 without causing the lifting and lowering.

The two protruding portions 3428 protrude from opposite sides of the second combining hole 3426 . The pressing portion 348 fills the second combining hole 3426 and covers the two second protruding portions 3428 so as to be fixed to the structural plate 342 . The pressing portion 348 has a pre-compression area 3482 , which faces the elastic restoring member 40 and can provide a preset pressure of the elastic restoring member 40 (ie, abuts against the top 40 a of the elastic restoring member 40 through the pre-compressing area 3482 ). When the keycap 34 is pressed, the elastic restoring member 40 is pressed through the pre-pressing area 3482 . For other descriptions of the pressing portion 348 and the opening 3426, reference may be made to the relevant descriptions of the pressing portion 148, the opening 1426 and the changes thereof, which will not be repeated.

As explained above, in the key structures 1 and 3, the key caps 14 and 34 are combined structures, and the structural plates 142 and 342 and the joint parts 144a, 144b, 144c, 344a and 344b made of different materials can be used, so it can be easily In this way, sufficient rigidity can be obtained, and the structural design flexibility of the keycaps 14 and 34 and the key structures 1 and 3 can be improved, which can solve or at least improve the design limitations of the single-structure keycaps in the prior art, and is beneficial to the key structure. Thin design. The joint parts 144a, 144b, 144c, 344a, 344b and the pressing parts 148, 348 are directly fixed on the structural plates 142, 342. When the key structures 1, 3 are actuated, the structural plates 142, 342 can directly bear the force transmission. This structure configuration can effectively maintain the stability of the keycaps 14 and 34, and can also make the key structures 1 and 3 act stably. In addition, the parts of the keycaps 14, 34 that contact the elastic reset members 22, 40 are implemented as pressing parts 148, 348, and this structural configuration is beneficial to adjust the structure size (ie, the pre-pressed areas 1482, 1482, 3482) to meet product specifications or product manufacturing requirements.
