[0032] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions in the embodiments of this patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this patent without inventive effort are within the scope of protection of this patent.

[0033] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the touchpad assembly structure provided by the patent embodiment comprises a bottom plate 1, a touch assembly 2, a transmission member 3 and an elastic member 4. The touch assembly 2 is used to receive the touch operation of the user. The touch assembly 2 is stacked with the bottom plate 1 along the stacking direction Z. The touch assembly 2 comprises a first area and a second area. The first area is connected with the bottom plate 1. The transmission member 3 is connected with the second area. The elastic member 4 is arranged between the bottom plate 1 and the transmission member 3 to reset the touch assembly 2 when the external force is removed. The transmission member 3 is provided with a limiting member 31 extending along the stacking direction Z. The bottom plate 1 is provided with a limiting hole 11. The limiting member 31 is in sliding fit with the limiting hole 11. The end of the limiting member 31 away from the transmission member 3 forms a limiting part. In the embodiment, the limiting member 31 is in sliding fit with the limiting hole 11. The limiting member 31 is provided with the limiting part. The travel of the limiting member 31 can be limited. The stability of the touch assembly 2 can be improved. The possibility of generating abnormal sound or tremolo can be reduced.

[0034] The touch assembly 2 is used to receive the touch operation of the user. The touch assembly 2 comprises a touch switch 221. The touch switch 221 is arranged corresponding to the abutting part 12 of the bottom plate 1.

[0035] The touch assembly 2 further comprises a touch panel 21 and a circuit board 22. The touch panel 21 and the circuit board 22 are stacked, i.e. the touch panel 21 is arranged above the circuit board 22. The touch switch 221 is arranged below the circuit board 22. The touch panel 21 is used to receive the touch operation of the user. The circuit board 22 can be a PCB board or a PCBA board.

[0036] Optionally, when the touch panel 21 is not pressed, the touch switch 221 has a gap with the abutting part 12. After the touch panel is pressed, the touch switch 221 abuts against the abutting part 12 to make the touch panel 21 generate a touch signal. Specifically, when the touch panel 21 is not pressed, no touch signal is generated. After the touch panel 21 is pressed, the abutting part 12 cooperates with the touch switch 221 to generate a touch signal.

[0037] Optionally, the touch switch 221 is provided with a metal spring piece. When the touch switch 221 is not pressed, the metal spring piece is in a natural state and does not contact the circuit board 22. After the abutting part 12 abuts against the touch switch 221, the metal spring piece is elastically deformed. The metal spring piece contacts the circuit board 22. An electric current path is generated between the metal spring piece and the circuit board 22 to trigger a touch signal.

[0038] Optionally, the transmission member 3 has a first end and a second end, the first end is connected with the touch assembly 2, and the second end is a limiting member 31 which is limited to the bottom plate 1 so that the first end has a movable interval with the bottom plate 1, and is used to drive the touch assembly 2 to move up and down along the height direction Z of the bottom plate 1, so that the touch switch 221 is in abutment with the abutment portion 12 when the touch assembly 2 is lowered under the action of an external force. Through the transmission member 3, the touch switch is in abutment with the abutment portion 12 when the touch assembly 2 moves downward, so that the touch switch can be triggered. That is, the first end has a movable gap with the bottom plate 1, so that the first end can move towards or away from the bottom plate 1, so that the touch switch can be in abutment with the abutment portion 12 after the first end moves downward.

[0039] Optionally, the first end is in the shape of a plate, and the first end extends along the length direction X of the bottom plate 1. The first end can be arranged close to the front side of the touch assembly 2, so that the touch assembly 2 can keep synchronous movement through the transmission member 3 when an operator presses the front side of the touch assembly 2.

[0040] The touch switch can be welded on the circuit board 22, or the touch switch can be fixed on the circuit board 22 through clamping or fasteners. The touch switch can be fixed in the central region of the circuit board 22, or can be fixed in the edge region. In the embodiment of the present disclosure, the touch switch can be arranged in the region close to the front side of the circuit board 22.

[0041] The abutment portion 12 can be a protruding structure formed on the bottom plate 1 towards the touch switch, and the protruding height of the protruding structure can be set according to actual needs.

[0042] Optionally, the first region and the second region are arranged at intervals along the width direction Y, the first region is close to the rear side of the electronic device, and the second region is close to the front side of the electronic device.

[0043] In some specific embodiments, the number of limiting members 31 is two, and the two limiting members 31 are arranged at the two ends of the length direction X of the transmission member 3; the second region is provided with the touch switch 221, and the two limiting members 31 are symmetrically arranged relative to the touch switch 221. The two limiting portions can limit the limiting members 31, and limit the movement stroke of the limiting members 31 in the limiting hole 11. The two limiting members 31 are symmetrically arranged relative to the touch switch 221, so that the transmission member 3 presents a seesaw structure with the touch switch 221 as the fulcrum, greatly improving the stability of the triggering force.

[0044] In some specific embodiments, the surface of the bottom plate 1 away from the touch assembly 2 is provided with a damping member 13, the damping member 13 is located on the periphery of the limiting hole 11, the damping member 13 is used to abut against the limiting portion, and direct contact between the limiting portion and the bottom plate 1 is avoided, so that the metallic impact sound of the touch assembly 2 triggered rebound can be eliminated, and the user experience is improved.

[0045] The damping member 13 can be made of rubber material or polyester film.

[0046] In some specific embodiments, the limiting portion comprises a hook portion, which improves the stability of the contact between the limiting portion and the bottom plate 1.

[0047] In some specific embodiments, the elastic member 4 comprises a connecting arm 41 and an elastic arm 42 connected to each other, the connecting arm 41 is connected to the bottom plate 1, and the end of the elastic arm 42 abuts against the transmission member 3. The elastic arm 42 is elastic so as to reset the touch assembly 2 when the external force is removed. The elastic member 4 can move the touch assembly 2 upward to reset, i.e., the touch assembly 2 can rebound to the initial position, which facilitates the touch assembly 2 to be pressed next time.

[0048] In some specific embodiments, the number of elastic members 4 is two, and the two elastic members 4 are arranged at intervals, which can improve the reset stability of the touch assembly 22.

[0049] In some specific embodiments, the touch assembly 2 comprises a touch panel 21 and a circuit board 22, the touch panel 21 is arranged above the circuit board 22, and a touch switch 221 is arranged below the circuit board 22. When the touch assembly 2 is lowered under the action of the external force, the touch switch 221 abuts against the abutting portion 12 arranged on the bottom plate 1.

[0050] In some specific embodiments, the bottom plate 1 is connected to the first area through the first structural adhesive 5, and the transmission member 3 is connected to the second area through the second structural adhesive 6. Compared with the existing method of fixing the touch assembly 2 and the cover through screws, in the embodiment of the present disclosure, the bottom plate 1 is connected to the first area through the first structural adhesive 5, and the transmission member 3 is connected to the second area through the second structural adhesive 6, which reduces the number of parts, simplifies the assembly method, and improves the assembly efficiency.

[0051] The first structural adhesive 5 and the second structural adhesive 6 can be adhesives, specifically double-sided tape or easy-to-pull adhesive.

[0052] In some specific embodiments, the transmission member 3 is formed with a flange structure 32 extending along the length direction of the transmission member 3, which greatly improves the rigidity of the transmission member 3 and makes the transmission member 3 not easy to deform. The transmission member 3 is provided with a limiting member 31 structure at both ends, forming a seesaw structure with the touch switch 221 as the fulcrum, which greatly improves the stability of the trigger force.
