Fig. 1 is a first angular schematic view of a touch pad assembly 100 according to an exemplary embodiment, fig. 2 is a second angular schematic view of the touch pad assembly 100 of fig. 1, fig. 3 is a partial structural schematic view of the touch pad assembly 100 of fig. 1, and fig. 4 is an exploded schematic view of the touch pad assembly 100 of fig. 1. As shown in fig. 1 to 4, the touch pad assembly 100 may include a movable assembly 1, a linkage assembly, and a base plate 2, wherein the base plate 2 and the movable assembly 1 may be disposed substantially in a stack, and a portion of the linkage assembly may be disposed between the movable assembly 1 and the base plate 2. Specifically, the back of the movable component 1 is provided with a touch switch 11, the bottom plate 2 can be arranged on the back of the movable component 1 towards the movable component 1, and after the touch pad component 100 is assembled in the electronic device, when the touch switch 11 is triggered, the function corresponding to the click operation can be realized.

As shown in fig. 3 and 4, the linkage assembly may include a bracket 3, a first balance bar 4 and a second balance bar 5, where the bracket 3 may be disposed on the back of the movable assembly 1 toward the touch switch 11, for example, the bracket 3 may be adhesively fixed with the movable assembly 1 or the bracket 3 may be locked with the movable assembly 1 by a locking member, which is not limited in this disclosure. The first balance bar 4 and the second balance bar 5 are respectively and rotatably arranged on the bracket 3, two ends of the first balance bar 4 are respectively and movably connected with the bottom plate 2, two ends of the second balance bar 5 are respectively and movably connected with the bottom plate 2, the first balance bar 4 and the second balance bar 5 are adjacently arranged, and one ends, close to each other, of the first balance bar 4 and the second balance bar 5 are respectively and closely arranged near the touch switch 11.

Based on this, after the touch pad assembly 100 is assembled to the electronic device, when the user needs to trigger the touch pad assembly 100 to implement a corresponding function, the user can press the front surface of the movable assembly 1, and through a gap between the movable assembly 1 and the base plate 2 near the side of the linkage assembly, the movable assembly 1 can tilt relative to the base plate 2, so that the movable assembly 1 can generate displacement in the second direction Z relative to the base plate 2, and generate a force acting on the touch switch 11 to trigger the touch switch 11. Moreover, during the process of moving the movable assembly 1 relative to the bottom plate 2, the bracket 3 can be driven to generate displacement in the second direction Z, and because the first balance bar 4 and the second balance bar 5 are respectively connected with the bottom plate 2, the movement of the first balance bar 4 and the second balance bar 5 in the second direction Z is limited, so that the first balance bar 4 and the second balance bar 5 can rotate around the first direction X relative to the bracket 3 under the combined action of the bracket 3 and the bottom plate 2, and meanwhile, the ends of the first balance bar 4 and the second balance bar 5 can move relative to the bottom plate 2 to adapt to the movement of the bracket 3. The first direction X is the length direction of the first balance bar 4 and the second balance bar 5, and the second direction Z is the stacking direction of the bottom plate 2 and the movable assembly 1.

Therefore, if the user presses the movable assembly 1at a position close to the bracket 3, if the user presses any position of the front side of the movable assembly 1, which is close to the side where the first balance bar 4 is disposed, the displacement synchronization of the front side of the movable assembly 1, which is close to the side where the first balance bar 4 is disposed, can be achieved through the rotation of the first balance bar 4 relative to the bracket 3, so that when any position of the front side of the movable assembly 1, which is close to the side where the first balance bar 4 is disposed, the stroke of the trigger switch 11 is triggered to be consistent; similarly, if a user presses any position of one side of the front surface of the movable assembly 1, which is close to the two balance bars, displacement synchronization can be realized through the second balance bars 5, so that the same pressing hand feeling is achieved, and user experience is improved; moreover, the length of the support 3 in the first direction X is matched through the two balance bars of the first balance bar 4 and the second balance bar 5, the movable assembly 1 is divided into two sides to perform displacement synchronization respectively, and compared with the scheme that a single balance bar is adopted in the first direction X, the length of the first balance bar 4 and the second balance bar 5 can be relatively shortened, the rigidity of the first balance bar 4 and the second balance bar 5 is improved, displacement difference caused by deformation of the first balance bar 4 and the second balance bar 5 is reduced, and synchronization accuracy of two ends of the first balance bar 4 and the second balance bar 5 in the first direction X is improved. When the user releases the pressing, the trigger switch 11 can be reset through the action of the trigger switch 11, and the same stroke can be generated through the actions of the first balance bar 4 and the second balance bar 5 in the process of releasing the trigger switch 11. In the embodiment provided in the present disclosure, taking the case that the trigger switch 11 is triggered, the first balance bar 4 and the second balance bar 5 are both rotated by the bracket 3 as an example, in fact, in other embodiments, one of the first balance bar 4 and the second balance bar 5 may also be rotated relative to the bracket 3, so as to realize displacement synchronization of the side of the movable assembly 1 corresponding to the first balance bar 4 or the side of the second balance bar 5, which is not limited in the present disclosure.

In this embodiment, in order to reduce the difference in feel due to the excessively large distance between the first balance bar 4 and the second balance bar 5 by transmitting the synchronous displacement to the tact switch 11 through the first balance bar 4 and the second balance bar 5, the orthographic projection of the tact switch 11 may be located between the orthographic projection of the first balance bar 4 and the orthographic projection of the second balance bar 5 in the thickness direction of the touch pad member 100, that is, the tact switch 11 may be located between the ends of the first balance bar 4 and the second balance bar 5 that are close to each other.

Wherein, the accommodating portion 31 may include a first groove, the rod 41 may be rotatably disposed in the first groove, the bracket 3 may include a plastic bracket, the rod 41 may be engaged in the accommodating portion 31 by using flexibility of the plastic bracket, and the rod 41 may rotate therein.

In this embodiment, the bracket 3 is a long-strip-shaped bracket, the length direction of the bracket 3 is set along the first direction X, and the portion of the accommodating portion 31 that mates with the rod 41 is a long-strip-shaped groove. By this arrangement, the rod 41 can be arranged along the first direction X, so that the displacements of the movable assembly 1 along the two sides of the first direction X are related, and when the right and left sides of the front face of the movable assembly 1 are pressed, the trigger strokes of the left side positions are basically consistent, and the trigger strokes of the right side positions are basically consistent.

The connection between the first balance bar 4 and the first mounting portion 21 is exemplified, and the connection between the second balance bar 5 and the first mounting portion 21 may refer to the connection between the first balance bar 4 and the first mounting portion 21. The connection manner between the first balance bar 4 and the first mounting portion 21 and the connection manner between the second balance bar 5 and the first mounting portion 21 may be different, for example, the connection manner shown in fig. 5 and 6 is adopted for the first balance bar 4 and the first mounting portion 21, and the connection manner shown in fig. 7 and 8 is adopted for the second balance bar 5 and the first mounting portion 21, which may be specifically designed according to the need, and the disclosure is not limited.

Specifically, the bracket 3 may further include a connection portion 34, a plurality of curved connection members 35, and a first through slot 36 disposed in the connection portion 34, where the connection portion 34 may be attached to the back surface of the circuit board 12, for example, the connection portion 34 may be bonded to the back surface of the circuit board 12, and one end of each curved connection member 35 is connected to an inner wall of the first through slot 36, and the other end is connected to the trigger portion 33. Based on this, the trigger portion 33 can be suspended in the first through groove 36 by the plurality of bending connectors 35, and the flexibility of the trigger portion 33 is improved by the bending connectors 35.

In the above embodiments, in some alternative embodiments, the back surface of the movable component 1 may be the back surface of the circuit board 12; in other alternative embodiments, such as those provided in the present disclosure, the movable assembly 1 may further include a reinforcing plate 14, where the reinforcing plate 14 is connected to the back surface of the circuit board 12, the reinforcing plate 14 may form the back surface of the movable assembly 1, the reinforcing plate 14 is disposed side by side with the bracket 3 along a third direction Y perpendicular to both the first direction X and the second direction Z, and a first side edge region (an upper edge region shown in fig. 7) of the bottom plate 2 along the third direction Y is engaged with the reinforcing plate 14, and a second side edge region (a lower edge region shown in fig. 7) of the bottom plate 2 along the third direction Y is engaged with the bracket 3. The extending direction of the first side edge area and the second side edge area is a first direction X, and in the embodiment shown in fig. 7, the first direction X may be understood as a length direction of the first balance bar 4 and the second balance bar 5, and the third direction Y may be understood as a width direction of the touch cover 13. The reinforcing plate 14 may be a metal plate, and the action of the reinforcing plate 14 can improve the rigidity of the whole movable assembly 1, which is beneficial to reducing the deformation of the movable assembly 1 caused by the action of the trigger switch 11. In the present embodiment, the reinforcing plate 14 substantially covers the circuit board 12, leaving a space in which the bracket 3 can be assembled, protecting the circuit board 12 to the maximum extent.

In some alternative embodiments, as shown in fig. 9, the reinforcing plate 14 may include a protrusion 141 extending toward the bracket 3 along the third direction, and the bracket 3 may include a groove 39 engaged with the protrusion 141, so that the connection between the reinforcing plate 14 and the bracket 3 may be achieved through the engagement of the protrusion 141 with the groove 39, and the stability of the connection between the bracket 3 and the movable assembly 1 may be enhanced. Of course, besides the clamping connection between the reinforcing plate 14 and the bracket 3 through the protrusion 141 and the groove 39, the bracket 3 may be connected to the movable assembly 1 in other manners, for example, the bracket 3 may be connected to the back of the circuit board 12 by an adhesive manner.

In still other alternative embodiments, the reinforcing plate 14 may include a plate body 142 and a plurality of bosses 143 provided at a side of the plate body 142 toward the bottom plate 2, the plurality of bosses 143 being provided side by side in the first direction X, and the plurality of bosses 143 being provided toward a first side edge region of the bottom plate 2, and the bracket 3 being provided toward a second side edge region of the bottom plate 2, the plurality of bosses 143 may be in contact with the bottom plate 2. On this basis, since the first side edge region of the base plate 2 is in contact with the plurality of bosses 143, since there is a certain height of the bosses 143, there is a certain gap between the second side edge region of the base plate 2 and the bracket 3, and a small-angle relative rotation can be generated between the base plate 2 and the movable assembly 1, with the rotation axis as shown in fig. 4. When the touch cover 13 is pressed, the movable assembly 1 rotates along the rotation axis, so that displacement is generated in the second direction relative to the bottom plate 2, and the first clamping part 42 moves relative to the first mounting part 21 due to the fact that the rod bodies 41 of the first balance rod 4 and the second balance rod 5 can rotate relatively in the first groove body, and triggering is completed after the trigger switch 11 reaches a set stroke. Whether the touch cover plate 13 is pressed on the right side or the left side on the front side, the displacement synchronization on the left side can be realized through the first balance bar 4 corresponding to the left side, the displacement synchronization on the right side can be realized through the second balance bar 5 corresponding to the right side, the purpose of consistent hand feeling at each position on the left side is achieved, the purpose of consistent hand feeling at each position on the right side is achieved, the pressing is easy, and the feedback is clear.

Specifically, the first buckle 145 may be a second bending rib formed by extending the reinforcing plate 14 toward the base plate 2, and the second buckle 23 may be a third bending rib formed by extending the base plate 2 toward the reinforcing plate 14, where the third bending rib and the second bending rib are hooked in the third direction Y, so as to limit the relative movement between the base plate 2 and the reinforcing plate 14 in the third direction.
