Description

Magnetic button and magnetic button manufacturing method thereof

The present invention relates to a push button and a method of manufacturing the same, and more particularly to a magnetic push button using magnetic attraction as a driving force required for resetting a keycap and a magnetic push button manufacturing method thereof.

In terms of current personal computer usage habits, the keyboard is one of the indispensable input devices for entering text, symbols or numbers. Moreover, the consumer electronics products that are in contact with everyday life or the large-scale processing equipment used in the industry need to have a button structure as an input device to operate the above-mentioned electronic products and processing equipment.

Please refer to FIG. 1, which is a schematic cross-sectional view of the prior art button 1. As shown in FIG. 1, the button 1 includes a bottom plate 10, a keycap 12, a circuit board 14, a support device 16, and an elastic member 18. The circuit board 14 is disposed on the bottom plate 10. The support device 16 is disposed between the keycap 12 and the bottom plate 10 for supporting the keycap 12. The elastic member 18 is also disposed between the keycap 12 and the bottom plate 10. When the keycap 12 is pressed by the user, the elastic member 18 provides an elastic restoring force of the keycap 12 to return the keycap 12 to the position before pressing.

However, since the design of the scissor-foot mechanism used by the support device 16 causes a large height space to be required, thereby further increasing the overall height of the button 1, it is disadvantageous for the application of thin keyboard. In addition, the elastic member 18 is often made of rubber, and the rubber has a fatigue condition under long-term use, thereby shortening the service life of the button 1.

One of the objects of the present invention is to provide a use of magnetic attraction for resetting as a keycap The driving force of the magnetic button and its magnetic button manufacturing method to solve the above problems.

According to an embodiment, the magnetic button of the present invention comprises a housing, a keycap, a first magnetic portion, a first connecting portion, and a first connecting portion, and a second magnetic portion. unit. The first connecting portion is pivotally connected to the housing and the second connecting portion is movably coupled to the key cap to move the key cap between the unpressed position and a pressed position along with the first bracket. The second magnetic portion corresponds to the first magnetic portion and is disposed on one of the keycap and the housing. At least one of the first magnetic portion and the second magnetic portion includes a permanent magnet material, and the permanent magnet material is magnetized by a magnetizing device after the first connecting portion is pivotally connected to the housing. When the keycap is not pressed, a magnetic attraction between the second magnetic portion and the first magnetic portion maintains the keycap in the undepressed position. When the key cap is pressed by an external force to cause the first magnetic portion to be away from the second magnetic portion, the key cap is moved to the pressing position by the first bracket from the unpressed position. When the external force is released, the magnetic attraction causes the first magnetic portion to be close to the second magnetic portion such that the keycap moves from the pressed position back to the undepressed position with the first bracket.

According to another embodiment, a magnetic button manufacturing method of the present invention includes providing a housing, a keycap, and a first bracket having a first magnetic portion, a first connecting portion, and a second connecting portion, Providing a second magnetic portion to the one of the keycap and the housing in a manner corresponding to the first magnetic portion, pivoting the first connecting portion to the housing, and moving the second connecting portion Connecting the keycap to move the keycap between the unpressed position and a pressing position, and using at least one of the first magnetic portion and the second magnetic portion by using a magnetizing device One of the contained permanent magnet materials is magnetized.

According to another embodiment, the magnetic button of the present invention comprises a housing, a keycap having a first magnetic portion, a supporting device, and a second magnetic portion. The supporting device is disposed between the keycap and the housing to move the keycap between an unpressed position and a pressed position. The second The magnetic portion corresponds to the first magnetic portion and is disposed on one of the housing and the supporting device. At least one of the first magnetic portion and the second magnetic portion includes a permanent magnet material, and the permanent magnet material is charged by the magnetizing device after the supporting device is disposed between the key cap and the housing. magnetic. When the keycap is not pressed, a magnetic attraction between the second magnetic portion and the first magnetic portion maintains the keycap in the undepressed position. When the key cap is pressed by an external force to cause the first magnetic portion to be apart from the second magnetic portion, the key cap is moved from the unpressed position to the pressed position. When the external force is released, the magnetic attraction causes the first magnetic portion to be close to the second magnetic portion such that the keycap moves from the pressed position back to the undepressed position.

According to another embodiment, a magnetic button manufacturing method of the present invention includes providing a housing, a key cap having a first magnetic portion, and a supporting device for aligning a second magnetic portion with the first magnetic portion. The method is disposed on one of the housing and the supporting device, and the supporting device is disposed between the keycap and the housing to move the keycap between an unpressed position and a pressed position, and A permanent magnet material included in at least one of the first magnetic portion and the second magnetic portion is magnetized using a magnetizing device.

In summary, the magnetic button provided by the present invention can omit the arrangement of the scissor-foot mechanism and the elastic member in the conventional button, thereby effectively reducing the space required for the overall button, so as to facilitate the subsequent thinning of the keyboard. And effectively extend the life of the button. In addition, the present invention not only effectively solves the problem that the magnetic portion attracts other components of the magnetic button during the process of assembling the magnetic button by performing the method of magnetizing after the assembly of the magnetic button is completed. The assembly process of the magnetic button is time-consuming and labor-intensive, and affects the assembly quality of the magnetic button. At the same time, it is also possible to locally adjust the magnetic portion by using the magnetizing device according to the actual performance of the magnetic button (such as pressing feedback feeling). The magnetic force is more in line with the user's operational needs.

Please refer to FIG. 2 to FIG. 5, FIG. 2 is a schematic diagram of a magnetic button 100 according to a first embodiment of the present invention, and FIG. 3 is a partially exploded view of the magnetic button 100 of FIG. The figure is an exploded view of the magnetic button 100 of Fig. 2, and Fig. 5 is a cross-sectional view of the magnetic button 100 of Fig. 2 along the section line AA. The magnetic button 100 includes a housing 102, a thin film circuit board 104, a keycap 106, a first bracket 108, a second bracket 110, and a magnetic portion 112. In this embodiment, the housing 102 can include a bottom plate 103, and the magnetic portion 112 is disposed on the bottom plate 103. The thin film circuit board 104 is stacked on the bottom plate 103 and has two switches 104a, 104b (shown in phantom in Figure 4). The first bracket 108 and the second bracket 110 are oppositely disposed between the bottom plate 103 and the keycap 106. The first bracket 108 has a magnetic portion 114 and at least one first connecting portion 116 (two are shown in FIG. 4, but not In this case, and at least one second connecting portion 118 (two shown in FIG. 4, but not limited thereto), the second bracket 110 has at least one third connecting portion 120 (shown in FIG. 4 And not limited to the fourth connecting portion 122 (two shown in FIG. 4, but not limited thereto), the magnetic portion 114 and the magnetic portion 112 correspond to each other, and the first connecting portion 116 The second connecting portion 118 is movably connected to the keycap 106, the third connecting portion 120 is pivotally connected to the bottom plate 103, and the fourth connecting portion 122 is movably connected to the keycap 106. Key cap 106 The first bracket 108 and the second bracket 110 can be stably moved up and down with respect to the bottom plate 103.

In the magnetic design of the magnetic portion 112 and the magnetic portion 114, the magnetic button 100 may adopt a design in which at least one of the magnetic portion 112 and the magnetic portion 114 includes a permanent magnetic material, wherein the permanent magnetic material may be made of a magnetizable material. Composition, such as NdFeB material. For example, in this embodiment, the magnetic portion 114 may comprise a sintered permanent magnet material in a block shape, in a structurally bonded manner (eg, adhesive, tight fit, card slot structure bonding, etc.) or buried incident molding. The method is disposed on the first bracket 108, or is formed in the first bracket 108 in a powder state and injection molding of the plastic material, and the magnetic portion 112 can be composed of a magnetic conductive material (for example, iron or other metal). Bonding (for example, adhesion, tight fitting, engagement of a card slot structure, etc.) or immersion molding is provided on the bottom plate 103 to generate magnetic attraction with the magnetized magnetic portion 114, but is not limited thereto.

That is, in another embodiment, the magnetic portion 112 may comprise a sintered permanent magnet material in a block shape, in a structurally bonded manner (eg, adhesive, tight fit, card slot structure bonding, etc.) or buried incident molding. The method is disposed on the bottom plate 103, or is formed in a powder state and plastic material injection molding (under the design of the bottom plate 103 which is an injection-molded structural member (such as a plastic plate member)), and the magnetic portion 114 is formed in the bottom plate 103. It may be composed of a magnetic conductive material (for example, iron or other metal), and is disposed on the first bracket 108 by means of structural bonding (for example, adhesion, tight fitting, engagement of a card slot structure, etc.) or by immersion molding. To generate magnetic attraction with the magnetized magnetic portion 112.

Alternatively, in another embodiment, the magnetic portion 114 may comprise a sintered permanent magnet material in a block shape and joined in a structural manner (eg, adhesive, tight fit, card slot structure bonding, etc.) or buried incident molding. The method is disposed on the first bracket 108, or is formed in the first bracket 108 in a powder state and injection molding of the plastic material. The magnetic portion 112 may comprise a sintered permanent magnet material in a block shape and structurally joined (for example). Adhesive, tight fit, the way the card slot structure is joined, etc.) or buried The injection molding method is disposed on the bottom plate 103, or is formed in the powder state and injection molding of the plastic material (under the design of the bottom plate 103 which is an injection-molded structural member (such as a plastic plate member)), thereby being formed in the bottom plate 103. The magnetic portions 112 and 114 can generate magnetic attraction after being magnetized. For other embodiments of the derivative changes, reference may be made to the analogy of the above embodiments, and details are not described herein again.

Through the above configuration, a magnetic attraction force (shown in FIG. 5 with a thick line with double arrows) can be generated between the magnetic portion 112 and the magnetic portion 114, so that the magnetic portion 112 and the magnetic portion 114 tend to approach each other, wherein the magnetic portion 114 directly The magnetic portion 112 is disposed, but not limited thereto; in principle, the magnetic portion 114 and the magnetic portion 112 are disposed only to make the magnetic force meet the product requirements, for example, the first bracket 108 and the second bracket 110 can be driven. Actuation, can provide the required press feedback feel (ie, the reaction force felt when the user presses). The magnetic attraction will force the magnetic portion 114 to the first bracket 108 and contact and apply force to the second bracket 110, thereby driving the keycap 106 to automatically return. In addition, when the keycap 106 is not pressed, the magnetic portion 114 is driven by the magnetic force to maintain contact with one of the linking portions 111 of the second bracket 110, and the linking portion 111 abuts the first bracket 108 to make the second bracket 110 and the first bracket When the second bracket 110 is rotated counterclockwise, the magnetic portion 114 can be lifted with a light force.

Please also refer to FIG. 6, which is a cross-sectional view of the magnetic button 100 when it is pressed to the pressing position. When the keycap 106 is pressed (as pressed by the force F1 as shown in FIG. 6), the first bracket 108 and the second bracket 110 are restrained by the keycap 106 and the bottom plate 103 to rotate clockwise and counterclockwise, respectively. Rotate. Since the magnetic portion 114 is disposed on the first bracket 108, the magnetic portion 114 will rotate in the same direction as the first bracket 108, that is, the magnetic portion 114 moves away from the magnetic portion 112 as the first bracket 108 rotates clockwise. In addition, when the second bracket 110 rotates counterclockwise, it can also contact and push the magnetic portion 114 to move away from the magnetic portion 112 via the interlocking portion 111. This phenomenon also contributes to the clockwise rotation of the first bracket 108. In this embodiment, a protrusion 109 is formed at a position corresponding to the switch 104a of the first bracket 108 and a corresponding switch 104b of the second bracket 110. When the keycap 106 is pressed, the protrusion 109 can contact the film. Circuit board 104 is used to trigger switches 104a, 104b. At this time, magnetic Although the magnetic attraction force (also shown by the thick line with double arrows in FIG. 6) generated between the magnetic portion 114 and the magnetic portion 112 is weakened, the magnetic portion 114 is kept moving toward the magnetic portion 112. After the external force F1 disappears, the magnetic force driving the magnetic portion 114 moves toward the magnetic portion 112; at the same time, the magnetic portion 114 applies the first bracket 108 and contacts and applies force to the second bracket 110 to drive the first bracket 108 and the second bracket. The counter 110 rotates counterclockwise and rotates clockwise, thereby moving the keycap 106 away from the bottom plate 103 to return to the home position (as shown in Fig. 5).

When the keycap 106 is pressed obliquely (for example, the key cap 106 shown in FIG. 7 is obliquely pressed to the right, wherein the external force F2 is substantially applied to the right side of the keycap 106), the magnetic portion 114 rotates clockwise along with the first bracket 108 and away from it. The magnetic portion 112 moves. Although the second bracket 110 is almost unrotated at this time, the first bracket 108 itself has the protrusion 109, and the protrusion 109 can still effectively press the membrane circuit board 104 to trigger the switch 104a; that is, the magnetic button 100 is still valid. Pressing, the tilting operation is still effective. Similarly, when the external force F2 disappears, the magnetic force drives the magnetic portion 114 to move toward the magnetic portion 112; meanwhile, the magnetic portion 114 applies a force to the first bracket 108 to drive the first bracket 108 to rotate counterclockwise, thereby moving the keycap 106 away from the bottom plate. 103 moves to return to the original position (as shown in Figure 5).

When the keycap 106 is only pressed to the left side by the external force F3 and moves toward the bottom plate 103 (as shown in FIG. 8, wherein the external force F3 is substantially applied to the left side of the keycap 106), the second bracket 110 is received by the bottom plate 103 and the keycap 106. Restricted and rotated counterclockwise. During the counterclockwise rotation of the second bracket 110, the magnetic portion 114 is driven by the magnetic force to remain in contact with the second bracket 100, so that the second bracket 110 rotates the first bracket 108 clockwise via the magnetic portion 114, thereby making the key The cap 106 as a whole remains generally horizontally downwardly moving, and the projections 109 are capable of pressing the membrane circuit board 104 to trigger the switches 104a, 104b. Similarly, when the external force F3 disappears, the magnetic force driving the magnetic portion 114 moves toward the magnetic portion 112; at the same time, the magnetic portion 114 applies force to the first bracket 108 and contacts and applies force to the second bracket 110 to drive the first bracket 108 and The second bracket 110 rotates counterclockwise and clockwise, respectively, thereby moving the keycap 106 away from the bottom plate 103 to return to the original position (as shown in FIG. 5). Therefore, in this case The operation of the keycap 106 is equivalent to the actuation of the keycap 106 in Fig. 6, and both move up and down substantially horizontally with respect to the bottom plate 103.

As described above, the magnetic attraction generated between the magnetic portion 114 and the magnetic portion 112 directly applies force to the first bracket 108 and the second bracket 110 and generates a rotational moment to the first bracket 108 and the second bracket 110, so that the magnetic force The suction exerts a stable and reliable effect on the first bracket 108 and the second bracket 110. In this embodiment, the first bracket 108 and the second bracket 112 are spaced apart from each other, that is, there is no direct connection or contact with each other, but the first bracket 108 can still pass through the magnetic portion 114 and can be affected by the actuation of the second bracket 110. The operation as shown in Fig. 8; however, the invention is not limited thereto. For example, in practice, the first bracket 108 and the second bracket 110 may still have structural direct contact or connection to improve the actuation relationship between the first bracket 108 and the second bracket 110.

It should be noted that the magnetic button 100 can be manufactured by using the magnetic button manufacturing method in FIG. 9. As can be seen from FIG. 9, first, step 900 is performed to provide the bottom plate 103, the key cap 106, the first bracket 108, and Second step 110; then, step 902 is performed, and the magnetic portion 112 is disposed on the bottom plate 103 corresponding to the magnetic portion 114. The arrangement of the magnetic portion 112 and the magnetic portion 114 can be as described above, and details are not described herein. And step 904 is performed, that is, the first connecting portion 116 of the first bracket 108 is pivotally connected to the bottom plate 103, and the second connecting portion 118 of the first bracket 108 is movably connected to the keycap 106, and the second bracket 110 is The third connecting portion 120 is pivotally connected to the bottom plate 103, and the fourth connecting portion 122 of the second bracket 110 is movably connected to the keycap 106 to complete the assembly of the magnetic button 100.

Finally, step 906 is performed to magnetize the permanent magnet material in the magnetic portion 114 using a magnetizing device. In short, it can feed the assembled magnetic button 100 into the magnetizing device and pass current. In the magnetic field formed by the magnetizing coil, the permanent magnet material in the magnetic portion 114 is magnetized to have magnetism, so that the magnetic portion 114 can generate a magnetic attraction force with the magnetic portion 112 as the key cap 106. The driving force of the automatic returning button is completed, so that the manufacturing process of the magnetic button 100 is completed. As for the other related descriptions of the magnetic button 100, reference may be made to the above embodiments, and details are not described herein. In this way, the present invention not only effectively solves the problem that the magnetic portion 114 and the magnetic button 100 are in the process of assembling the magnetic button 100 through the above-described manufacturing method of performing magnetization after the assembly of the magnetic button 100 is completed. The components (such as the magnetic portion 112) attract each other, which causes the assembly process of the magnetic button 100 to be time-consuming and labor-intensive and affects the assembly quality of the magnetic button 100, and can also achieve the use of the magnetizing device according to the magnetic button 100. The performance (such as pressing feedback feel, etc.) locally adjusts the magnetic force of the magnetic portion 114 to more closely meet the user's operational needs.

Referring to FIGS. 10 to 13, FIG. 10 is a perspective view of a magnetic button 200 according to a second embodiment of the present invention, and FIG. 11 is an exploded view of the magnetic button 200 of FIG. Fig. 12 is a cross-sectional view of the magnetic button 200 of Fig. 10 taken along line BB, and Fig. 13 is a cross-sectional view of the key cap 204 of Fig. 12 when it is pressed. As shown in FIGS. 10 to 13, the magnetic button 200 includes a bottom plate 202, a key cap 204, a first bracket 206, a second bracket 208, and a thin film circuit board 210. In this embodiment, the bottom plate 202 is the housing of the magnetic button 200.

The first bracket 206 has a first connecting portion 212 and a second connecting portion 214. The second bracket 208 has a third connecting portion 216 and a fourth connecting portion 218. The first connecting portion 212 and the third connecting portion 216 are included. The bottom plate 202 is rotatably connected, and the second connecting portion 214 and the fourth connecting portion 218 are rotatably connected to the key cap 204, whereby the key cap 204 can be accompanied by the first bracket 206 and the second bracket 208. The unpressed position shown in Fig. 12 moves between the pressed position as shown in Fig. 13. In addition, the first bracket 206 further has a first linking portion 220, and the second bracket 208 further has a second linking portion 222. The first linking portion 220 abuts the second bracket 208, and the second linking portion 222 and the second portion A bracket 206 abuts to cause the first bracket 206 and the second bracket 208 to interlock when the keycap 204 is pressed or the external force is released.

The magnetic button 205 further includes a magnetic portion 224. The magnetic portion 224 is disposed on the keycap 204. The first bracket 206 (or the second bracket 208) has a magnetic portion 226. In this embodiment, the magnetic button 200 can be At least one of the magnetic portion 224 and the magnetic portion 226 includes a design of a permanent magnet material, wherein the permanent magnet material may be composed of a magnetizable material, such as a neodymium iron boron material or the like. For example, in this embodiment, the magnetic portion 226 may comprise a sintered permanent magnet material in a block shape, in a structurally bonded manner (eg, adhesive, tight fit, card slot structure bonding, etc.) or buried incident molding. The method is disposed on the first bracket 206 (or the second bracket 208), or is formed in the first bracket 206 (or the second bracket 208) in a powder state and injection molding of the plastic material, and the magnetic portion 224 can be magnetically conductive. The material (for example, iron or other metal) is formed on the keycap 204 by structural bonding (for example, adhesion, tight fitting, bonding of a card slot structure, etc.) or by immersion molding, thereby being magnetized. The magnetic portion 226 generates magnetic attraction, but is not limited thereto. Other related derivative variations may be analogized with reference to the above embodiments, and details are not described herein again.

When the keycap 204 is not pressed, the magnetic attraction between the magnetic portion 226 and the magnetic portion 224 maintains the keycap 204 in the undepressed position as shown in FIG. When the key cap 204 is pressed by an external force, and the force is sufficient to overcome the magnetic attraction force to cause the magnetic portion 226 to move away from the magnetic portion 224, the magnetic portion 224 is rotated with the first connecting portion 214 as a fulcrum, so that the key cap 204 is accompanied by the first bracket 206. And the second holder 208 is moved to the pressing position as shown in Fig. 13 by the unpressed position as shown in Fig. 12.

When the hour hand is rotated, the keycap 702 is moved back to the unpressed position as shown in FIG. 32 with the link 710 and the male pivoting structure 712 by the pressing position as shown in FIG. 33, thereby achieving the purpose of automatic return.

The magnetic button 700 can be manufactured by referring to step 900, step 902, step 904, and step 906 in FIG. 9. The main difference between the manufacturing method of the magnetic button 700 and the manufacturing method of the magnetic button 100 is the magnetic button. In the 700 series, the two magnetic portions are respectively disposed on the position of the corresponding sliding portion of the key cap and the connecting rod of the supporting device to generate the lateral magnetic attraction. For the related description and the achievable functions thereof, reference may be made to the first embodiment. The related description is analogous and will not be described here.

In summary, the magnetic button provided by the present invention can omit the scissors in the conventional button. The configuration of the foot mechanism and the elastic member effectively reduces the space required for the entire button to facilitate the subsequent thinning of the keyboard and effectively extend the life of the button. In addition, the present invention not only effectively solves the problem that the magnetic portion attracts other components of the magnetic button during the process of assembling the magnetic button by performing the method of magnetizing after the assembly of the magnetic button is completed. The assembly process of the magnetic button is time-consuming and labor-intensive, and affects the assembly quality of the magnetic button. At the same time, it is also possible to locally adjust the magnetic portion by using the magnetizing device according to the actual performance of the magnetic button (such as pressing feedback feeling). The magnetic force is more in line with the user's operational needs.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
