[0035] In the embodiment, the balancing assembly 2 is used as an elastic supporting structure of the touch module plate 1 and a structure for triggering a key switch, the supporting bottom plate 3 is used as a supporting structure of the balancing assembly 2, when in use, pressing any corner part of the touch module plate 1 can pry the middle region of the balancing assembly 2 in a manner of fulcrum, the fulcrum is arranged between the middle region and the outer circumferential region of the balancing assembly 2, so as to improve the leverage and trigger the touch module plate 1 after the middle region of the balancing assembly 2 is deformed, so as to realize the clicking and pressing action of the mouse, and the difference in pressing force of the corner region of the touch module plate 1 is reduced.

[0036] In summary, the full-area touchpad can effectively reduce the difference in pressing force of the touchpad at any position, and further improve the user experience.

[0037] In the embodiment, the balance assembly 2 has a butterfly-shaped structure as a whole, and is provided with a fulcrum connecting portion 21, a prying portion 22, and at least two outer extension plates 23. The fulcrum connecting portion 21 is arranged around the prying portion 22 and is fixedly connected with the prying portion 21. The at least two outer extension plates 23 are fixedly connected with the fulcrum connecting portion 21 respectively and are distributed outwardly. The fulcrum connecting portion 21 can be a planar geometric structure composed of a plurality of separate fulcrums, can form a circular, triangular, polygonal, or other geometric structure, or can be a geometric structure directly formed by the entire fulcrum connecting portion 21. The fulcrum connecting portion 21 is fixedly connected with the support bottom plate 3. The touch module plate 1 is fixedly connected with the balance assembly 2 and covers the outer extension plates. The touch module plate 1 is provided with a key switch 11. The prying portion 22 has a spacing with the key switch 11 and is aligned with the key switch 11. Pressing any corner portion of the touch module plate 1 can press the outer extension plate 23, pry the prying portion 22 by taking the fulcrum connecting portion 21 as a fulcrum, make the prying portion 22 rise and trigger the key switch 11. The balance assembly 2 is used as an elastic supporting structure of the touch module plate 1 and a structure for triggering the key switch 11. The support bottom plate 3 is used as a supporting structure of the balance assembly 2. When in use, the touch module plate 1 does not have an upper touch area and a lower pressing area. Any area of the touch module plate 1 can be touched or directly pressed. When any corner portion of the touch module plate 1 is pressed (any corner portion is an area from the fulcrum connecting portion 21 to the outer extension plate 23), the outer extension plate 23 can be pressed, the prying portion 22 is pryed by taking the fulcrum connecting portion 21 as a fulcrum, the prying portion 22 rises and triggers the key switch 11. The fulcrum connecting portion 21 is used as a fulcrum structure for prying the prying portion 22 by the outer extension plate 23. When any corner portion of the touch module plate 1 is pressed, the user can press with a proper force. In the pressing process, the key switch 11 is easily triggered under the lever action of the prying portion 22, the fulcrum connecting portion 21, and the outer extension plate 23. When the middle area of the touch module plate 1 is pressed (the middle area of the touch module plate 1 is an area from the fulcrum connecting portion 21 to the prying portion 22), the touch module plate 1 is directly pressed downward, the key switch 11 is directly moved downward, contacts with the prying portion 22, and is thus triggered. In this way, the difference in pressing force at different parts of the touch plate is reduced, and the user experience is improved.

[0038] In the embodiment, the prying part 22 comprises a deformation plate 222 and at least one pressing piece 221, the deformation plate 222 is aligned with the key switch 11, one side of the deformation plate 222 is provided with two connecting arm plates 2221 and a spacing groove 2222, the spacing groove 2222 is located between the two connecting arm plates 2221, all the pressing pieces 221 are located below the two connecting arm plates 2221 and support the two connecting arm plates 2221, all the pressing pieces cross the spacing groove 2222, and the two connecting arm plates 2221 are fixedly connected with the fulcrum connecting part 21 respectively; when any corner part of the touch module plate 1 is pressed, the touch module plate 1 is inclined and sunken in the pressed area, that is, the whole touch module plate 1 is in a sunken state, so as to press more outer extension plates 23, the outer extension plates 23 are moved downward, and the fulcrum connecting part 21 is used as a fulcrum to pry the prying part 22, at this time, the pressing piece 221 is used as a support structure of the two connecting arm plates 2221, that is, when the outer extension plate 23 close to one of the connecting arm plates 2221 is moved downward, the outer extension plate 23 drives the connecting arm plate 2221 to pry through the fulcrum effect of the fulcrum connecting part 21, in order to prevent the connecting arm plate 2221 from moving downward with the outer extension plate 23, the pressing piece 221 is arranged as a fulcrum of the connecting arm plate 2221, so as to improve the angle of the connecting arm plate 2221, the connecting arm plate 2221 is upwardly tilted under the support effect of the pressing piece 221, since the connecting arm plate 2221 is fixedly connected with one side of the deformation plate 222, the part of the deformation plate 222 close to the connecting arm plate 2221 is tilted, a deformation in the form of twisting is formed, and then the key switch 11 is pressed to trigger the key switch 11, since the deformation plate 222 is deformed, the other connecting arm plate 2221 is also tilted to a certain degree, but the height of the tilt is not higher than the height of the tilt of the connecting arm plate 2221 driven by the outer extension plate 23.

[0039] In the embodiment, the upper surface of the deformation plate 222 is provided with a pressing gasket 2223, the pressing gasket 2223 is aligned with the key switch 11, the pressing gasket 2223 is a soft structure and has a supporting force, when one of the connecting arm plates 2221 is tilted, the deformation of the deformation plate 222 lifts the pressing gasket 2223 to trigger the key switch 11.

[0040] In the embodiment, the fixed part 31 is arranged on the support bottom plate 3, and one end of the fulcrum connecting part 21 is fixedly connected with the fixed part 31. The fixed part 31 can be a planar geometric structure composed of multiple single fulcrums, can form a circular, triangular, polygonal geometric structure, or can be a geometric structure directly formed by the whole fixed part 31. The planar geometric shape of the fixed part 31 corresponds to the planar geometric shape of the fulcrum connecting part 21. The fixed part 31 is used to provide a structure fixedly connected with the fulcrum connecting part 21 for the support bottom plate 3, so as to support the balance assembly 2, so that the balance assembly 2 maintains a distance from the support bottom plate 3, thereby facilitating the pressing of the touch module plate 1.

[0041] In the embodiment, the fulcrum connecting part 21 includes a connecting plate 211, a first avoiding groove 212, and an elastic connecting plate 213. Two sides of the connecting plate 211 are fixedly connected with the prying part 22 and an outer extension plate 23 respectively. That is, one side of the connecting plate 211 is fixedly connected with the connecting arm plate 2221, and the other side of the connecting plate 211 is fixedly connected with the outer extension plate 23. The elastic connecting plate 213 is fixedly connected with the connecting plate 211 and extends into the first avoiding groove 212. One end of the elastic connecting plate 213 is fixedly connected with the fixed part 31. The first avoiding groove 212 is used to provide a deformation space for the elastic connecting plate 213. When the touch module plate 1 is pressed at any corner part by the force F1, the outer extension plate 23 moves downward. Under the elastic action of the elastic connecting plate 213, the whole connecting plate 211 will tilt and move downward. However, the moving amount of the part of the connecting plate 211 close to the outer extension plate 23 will be greater than that of the part of the connecting plate 211 close to the prying part 22. Under the fulcrum action of the pressing piece 221, the part of the connecting plate 211 close to the prying part 22 will drive one side of the connecting arm plate 2221 to move downward and pry the other side of the connecting arm plate 2221 to move upward, so that the prying part 22 moves upward to trigger the key switch 11. When the pressing force on the touch module plate 1 at any corner part is removed, the elastic connecting plate 213 resets, drives the outer extension plate 23 to reset, and resets the touch module plate 1.

[0042] In the embodiment, the fixed part 31 includes a first support boss 311 and a locking piece 312. The elastic connecting plate 213 abuts against the upper surface of the first support boss 311. When the balance assembly 2 is assembled and fixed, the locking piece 312 is sequentially penetrated through the first support boss 311, the elastic connecting plate 213, and fixedly connected with the elastic connecting plate 213 from the lower surface of the first support boss 311, so that the assembly and fixation of the balance assembly 2 are completed. The first support boss 311 is used to provide a support structure for the elastic connecting plate 213, so that the prying part 22 and the outer extension plate 23 are lifted, thereby facilitating the lifting of the prying part 22 when the outer extension plate 23 moves downward.

[0043] In the embodiment, the balancing assembly 2 is provided with reinforcing plates 24, the number of reinforcing plates 24 is a, the number of overhanging plates 23 is b, b=2a, one end of each reinforcing plate 24 is fixedly connected with one end of two overhanging plates 23, and the bottom of the touch module plate 1 is fixedly connected with the top of the reinforcing plate 24; the reinforcing plate 24 is used to strengthen the structural stability of the overhanging plate 23, so that the overhanging plate 23 can maintain a horizontal state when the touch module plate 1 is not pressed, and at the same time, the reinforcing plate 24 is also used to transmit the pressing force on the touch module plate 1 to the overhanging plate 23, for example, when the user presses the touch module plate 1, the pressing area is just above the middle of the reinforcing plate 24, and the pressing area is not within the range of the overhanging plate 23 at this time, but under the drive of the reinforcing plate 24, the reinforcing plate 24 moves downward and drives the two overhanging plates 23 to move downward, so that the two overhanging plates 23 pry the prying part 22 together to trigger the key switch 11.

[0044] In the embodiment, the supporting bottom plate 3 is provided with second avoiding grooves 32 which are the same in number as the overhanging plates 23, the second avoiding grooves 32 correspond to the overhanging plates 23 one by one, the overhanging plates 23 are aligned with the second avoiding grooves 32, and the second avoiding grooves 32 provide a avoiding space for the downward movement of the overhanging plate 23, so that the overhanging plate 23 can move a sufficient distance to trigger the key switch 11.

[0045] In the embodiment, the supporting bottom plate 3 is provided with a second supporting boss 33 which is located below the prying part 22, the second supporting boss 33 is in contact with the prying part 22, and the second supporting boss 33 is arranged to support the prying part 22, so that the prying part 22, the fulcrum connecting part 21 and the overhanging plate 23 are on the same horizontal plane.

[0046] In the embodiment, the touch module plate 1 includes a cover plate 12 and a touch assembly 13, the cover plate 12 is located on the upper surface of the touch assembly 13 and is fixedly connected with the touch assembly 13, the lower surface of the touch assembly 13 is fixedly connected with the upper surface of the balancing assembly 2, and the key switch 11 is fixedly connected with the lower surface of the touch assembly 13; the cover plate 12 is used to protect the touch assembly 13, and the touch assembly 13 is used to provide a finger touch operation computer accessory for the user to move the cursor, when using the touch module plate 1, the user can directly swipe on the cover plate 12 with the finger to trigger the touch assembly 13 to work, and when key confirmation is needed, the user can press any position of the cover plate 12, at this time, the pressing force on the cover plate 12 is directly transmitted to the balancing assembly 2 through the touch assembly, and then the balancing assembly 2 easily triggers the key switch 11 through the lever action of the prying part 22, the fulcrum connecting part 21 and the overhanging plate 23.
