This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
First, referring to fig. 1A and 1B, fig. 1A is a perspective exploded view of a touch pad module according to an embodiment of the present invention; fig. 1B is an exploded perspective view of the touch pad module according to another view angle provided by the present invention. The touch panel module 1 is suitable for an electronic device, such as: notebook computer, keyboard, mobile phone, PDA, writing pad or drawing pad. The touch panel module 1 includes: the touch pad 10, the elastic body structure 20, the support frame 30, the base plate 40 and the locking member 50.
The touch panel 10 includes a circuit board 101 and a cover plate 102 disposed on the circuit board 101, and a push switch 1011 is disposed on a lower surface of the circuit board 101. The cover plate 102 may be fixed on the upper surface of the circuit board 101 in an adhesive manner, and may be pressed or slid by a user's finger. In this embodiment, the cover plate 102 may be made of: ceramic or glass, and in another preferred embodiment, the cover plate 102 may be made of sapphire glass.
The elastic body structure 20 is fixedly disposed on the lower surface of the circuit board 101 and covers the push switch 1011 at the same time, so that when the elastic body structure 20 deforms due to a force, the elastic body structure can contact and trigger the push switch 1011, and the push switch 1011 generates a corresponding push signal.
The bottom surface of the supporting frame 30 has a groove 301, the groove 301 is used for accommodating the bottom plate 40, and the groove 301 has a first opening 3011 penetrating through the supporting frame 30. In this embodiment, two or more first locking holes 3012 are disposed on the bottom surface of the groove 301, and the first locking holes 3012 are located around the first opening 3011.
The bottom plate 40 includes a limiting groove 401, two or more second locking holes 402 and a second opening 403. The position of the limiting groove 401 corresponds to the position of the elastic body structure 20, and the bottom surface of the limiting groove 401 has a through adjusting hole 4011. The second locking holes 402 penetrate through the bottom plate 40, and the positions of the second locking holes 402 correspond to the positions of the first locking holes 3012, respectively. In the present embodiment, the second locking holes 402 are disposed on the plurality of protrusions on the side edge of the bottom plate 40. The second opening 403 extends through and is located at or near the center of the bottom plate 40, which can be used to reduce the weight of the bottom plate 40.
With reference to fig. 1A and fig. 1B, the touch pad 10 is movably disposed in the first opening 3011 of the supporting frame 30, for example: the touch pad 10 may be coupled to the support frame 30 by a hinge structure (not shown) or a connection structure (not shown) having elasticity, so that the touch pad 10 disposed in the first opening 3011 can swing or vertically move with respect to the support frame 30. The locking member 50 is sequentially inserted through the second locking hole 402 and the first locking hole 3012 to fix the bottom plate 40 in the groove 301 on the lower surface of the supporting frame 30. Although the embodiment of the present invention only proposes to combine the bottom plate 40 and the supporting frame 30 in a locking manner, in practical applications, the bottom plate 40 and the supporting frame 30 may also be combined in an adhesive, welding or clamping manner, and in another embodiment, the bottom plate 40 and the supporting frame 30 may be manufactured in an integrated manner. In some possible embodiments, the lower surface of the supporting frame 30 is not designed with the groove 301, and the bottom plate 40 is directly fixed to the lower surface of the supporting frame 30.
When a user presses the touch pad 10 through the cover plate 102, one end of the elastic body structure 20 away from the circuit board 101 abuts against the bottom surface of the limiting groove 401, so that the elastic body structure 20 is deformed by being pressed by the bottom plate 40, and can contact and trigger the press switch 1011, so that the touch pad module 1 generates a corresponding press signal; when the touch pad 10 is not pressed, the touch pad 10 is reset, and at this time, the elastic body structure 20 is elastically restored, and one end of the elastic body structure 20 away from the circuit board 101 continuously abuts against the bottom surface of the limiting groove 401.
Referring to fig. 2A and 2B, fig. 2A is a schematic perspective view of a touch pad module according to the present invention; FIG. 2B is a schematic cross-sectional view of the touch pad module of FIG. 2A along the line A-A'. In fig. 2B, the elastic body structure 20 includes an elastic element 21 and an adjusting element 22, and the adjusting element 22 is adjustably disposed at an end of the elastic element 21 away from the touch pad 10. The elastic member 21 includes an elastic support portion 211 and an end portion 212 connected thereto. The elastic support 211 is used to combine with the circuit board 101 and cover the push switch 1011, and the end 212 has a screw hole 2121, and the screw hole 2121 has an internal thread structure (not shown). In the embodiment, the elastic member 21 is made of an elastic material, and the elastic supporting portion 211 and the end portion 212 are integrally formed. Alternatively, the elastic support 211 is a metal dome spring, the end 212 is made of plastic material, and the end 212 can be fixed on the elastic support 211 by injection or adhesion.
On the other hand, the adjusting member 22 has a screw 222 and an associated head 221. Wherein the screw 222 has an external thread structure (not shown) corresponding to the internal thread structure of the screw hole 2121, so that the screw 222 is adjustably inserted into the screw hole 2121. In addition, the other surface of the head 221 opposite to the connecting screw 222 abuts against the bottom surface of the limiting groove 401, and the surface is provided with a driving groove 2211 corresponding to the adjusting hole 4011 of the limiting groove 401. The shape of the driving groove 2211 may be: a straight line shape, a cross shape, a meter shape, a quadrangle shape, a hexagon shape, a star shape or a quincunx shape. Thus, when the tolerance formed by the stacked structure of the touch pad 10 is to be corrected, an adjustment tool (not shown) may be used, for example: a screwdriver passing through the adjusting hole 4011 and engaged with the driving slot 2211 of the head 221 to rotate the adjusting element 22 to adjust the relative position between the adjusting element 22 and the elastic element 21, for example, when the adjusting element 22 is rotated by an adjusting tool in a counterclockwise direction, the head 221 abutting against the bottom surface of the limiting groove 401 gradually gets away from the end 212, and the screw 222 simultaneously drives the end 212 to move toward the circuit board 101, so that the elastic supporting portion 211 is gradually compressed and approaches the push switch 1011, thereby shortening the push stroke of the touch pad 10; when the adjustment member 22 is rotated clockwise by the adjustment tool, the head 221 abutting against the bottom surface of the limiting groove 401 gradually approaches the end 212, and the screw 222 drives the end 212 to move away from the circuit board 101, so that the elastic supporting portion 211 gradually elastically extends and moves away from the push switch 1011, thereby increasing the push stroke of the touch pad 10.
Referring to fig. 3, fig. 3 is a cross-sectional view of another embodiment of the elastomer structure of the present invention. In fig. 3, the elastic structure 20 ' also includes an elastic member 21 ' and an adjusting member 22 '. The function of the elastic body structure is the same as that of the elastic body structure 20 in fig. 2B, and thus, the description thereof is omitted. The only difference from fig. 2B is that the end 212 'of the elastic member 21' is a screw having an external thread structure (not shown in the drawings); adjusting member 22 'has a threaded bore 221' corresponding to end 212 ', and threaded bore 221' has an internal threaded configuration (not shown) corresponding to the external threaded configuration of end 212 ', such that adjusting member 22' is adjustably mounted over end 212 'via threaded bore 221'. For example, the adjusting member 22 'can be a nut, and the adjusting tool can pass through the adjusting hole 4011 (as shown in fig. 2B) and be engaged in the driving groove 222' of the adjusting member 22 'to rotate the adjusting member 22' to adjust the relative position of the adjusting member 22 'and the elastic member 21'.
Compared with the prior art, the elastic body structure of the touch pad module provided by the invention is provided with the elastic part and the adjusting part, and the deformation range of the elastic part when the elastic part is stressed can be adjusted by using the adjusting part, so that the tolerance caused by the laminated structure of the touch pad is corrected, and the pressing stroke of the touch pad module cannot be changed due to different tolerances of the laminated structure; therefore, the present invention is a creation with great industrial value.
The invention may be modified in various ways by anyone skilled in the art without however departing from the scope of the appended claims.
