In the preferred embodiment of the invention, the pressure sensing unit 24 is disposed at the second cantilever portion 211b.

In the preferred embodiment of the present invention, the pressure sensing unit 24 may be, but is not limited to, a microelectromechanical accelerometer (MEMS Accelerometer), for example. The flexible circuit board 25 further includes two positioning holes h3, and the two positioning holes h3 are used to position with the two positioning holes h2 on the second cantilever portion 211b.

The following is a further explanation of the operation of the touch panel module 2 of the present invention.

Please refer to FIG. 4A and FIG. 4B together. When the substrate 22 is not subjected to contact pressure, the plurality of cantilevers 211 respectively support the plurality of connectors 23. In other words, the plurality of first cantilever parts 211a support the plurality of first connectors 23a, and the second cantilever parts 211b support the second connectors 23b, so that the substrate 22 and the elastic bracket 21 have a first distance G1.

Please refer to FIG. 5A and FIG. 5B. When the substrate 22 is pressed by an external force, the pressure is transmitted to the at least one cantilever 211 through the at least one connecting member 23. The at least one free end R rotates relative to the at least one fixed end F toward a side away from the substrate 22, so that the substrate 22 moves toward the elastic support 21. The distance between the substrate 22 and the elastic support 21 changes from the first distance G1 to the second distance G2. The distance G2 is smaller than the first distance G1, causing the pressure sensing unit 24 to deform. The pressure sensing unit 24 senses the contact pressure applied to the substrate 22 according to the deformation. The pressure sensing unit 24 then outputs a pressure sensing signal to the control unit C. When the contact pressure reaches a preset threshold, the control unit C reports to the processor 15 of the electronic computer 1 to realize the function of the left or right mouse button.

Since the pressure sensing unit 24 of the touch module 2 of the present invention is arranged close to the geometric center of the substrate 22, the same touch force applied to the geometric center of the substrate 22 or to the surrounding areas of the substrate 22 will vary depending on the force application point. Different distances from the pressure sensing unit 24 result in differences in the pressure values detected by the pressure sensing unit 24 . In a preferred embodiment of the invention, the touch panel module 2 further includes firmware S, and the firmware S is stored in the control unit C. The firmware S is used to correct the touch pressure sensitivity everywhere on the substrate 22 so that the touch pressure sensitivity everywhere on the substrate 22 is controlled within a tolerance range. The tolerance range may be, but is not limited to, for example: ten percent.

For example, when the user applies a touch pressure near the geometric center of the substrate 22, the touch pressure will be transmitted to the second free end R2 through the second connector 23b, and the second free end R2 will rotate away from the substrate 22 relative to the second fixed end F2, so that the substrate 22 moves toward the elastic bracket 21, further causing the pressure sensing unit 24 to deform, and the pressure sensing unit 24 will output a pressure sensing signal to the control unit C. When the touch pressure reaches a preset threshold, for example, 150 grams, the control unit C reports to the processor 15 of the electronic computer 1 to realize the functions of the left and right keys of the mouse.

When the user applies the same touch pressure as described above to the corner of the substrate 22, that is, to the periphery or edge of the substrate 22, the touch pressure will be transmitted to any first free end R1 through any first connector 23a, and the first free end R1 will rotate away from the substrate 22 relative to the first fixed end F1, so that the substrate 22 moves toward the elastic bracket 21, further causing the pressure sensing unit 24 to deform, and the pressure sensing unit 24 will output a pressure sensing signal to the control unit C. However, due to the first cantilever portion 211a and the pressure sensing unit The distance between the second cantilever portion 211b and the pressure sensing unit 24 is longer than the distance between the second cantilever portion 211b and the pressure sensing unit 24. Therefore, the deformation of the pressure sensing unit 24 caused by the same touch pressure will be different from the above situation. Therefore, the touch pressure applied to the substrate 22 sensed by the pressure sensing unit 24 will also be different. After further calibration by the firmware S, the touch pressure sensitivity of each point on the substrate 22 can be within the tolerance range, for example, within the range of plus or minus 10%. The advantage of this design is that the touch pressure sensitivity of each point of the touch panel module 2 is uniform.

In summary, the advantage of this invention is that it only uses a single pressure sensing unit 24 to sense the touch pressure of a small-area touch panel module (for example, no more than 120mm*70mm). The overall structure is relatively simple, which effectively reduces the manufacturing cost and the overall weight.

However, the above is only the best embodiment of this creation, and it cannot be used to limit the scope of implementation of this creation. That is, all simple equivalent changes and modifications made according to the scope of the patent application and the new description of this creation are still within the scope of this creation. In addition, any embodiment or patent application of this creation does not need to achieve all the purposes, advantages or features disclosed by this creation. In addition, the abstract and title are only used to assist in searching patent documents, and are not used to limit the scope of rights of this new model. In addition, the terms "first" and "second" mentioned in this specification or patent application are only used to name the element or distinguish different embodiments or scopes, and are not used to limit the upper or lower limit of the number of elements.
