DETAILED DESCRIPTION

[0031] In order to keep the following description of the embodiment of the present application clear and brief, the present application omits the detailed description of known functions and known components.

[0032] The embodiment of the present application provides a touchpad assembly which is applied to an electronic device, and the electronic device can be a notebook computer or other device which needs to be installed with a touchpad. The electronic device comprises a shell 7, and the shell 7 is provided with a mounting groove for placing the touchpad assembly. Referring to Figure 3 .

[0033] As shown in the figure, Figure 1 The touchpad assembly in the embodiment comprises a touch panel 1, a bar-shaped elastic sheet 2 and a push mechanism 3.

[0034] The touch panel 1 is arranged in the mounting groove on the shell 7, and the touch panel 1 has a pressing side. The bar-shaped elastic sheet 2 is arranged below the pressing side of the touch panel 1, the middle part of the bar-shaped elastic sheet 2 is arched downward, and the two ends are respectively tilted upward and abut against the lower surface of the pressing side of the touch panel 1. The push mechanism 3 is used for pushing the middle part of the bar-shaped elastic sheet 2 to move along the touch direction perpendicular to the touch panel 1, so as to change the extension length of the bar-shaped elastic sheet 2. The touch direction herein can be understood as the pressing direction of the touch panel 1, that is, the direction perpendicular to the panel surface of the touch panel 1.

[0035] It is easy to know that the pressing force of the pressing side of the touchpad 1 in the embodiment depends on the lifting degree of the two ends of the strip-shaped elastic sheet 2. For example, if the pushing mechanism 3 pushes the middle part of the strip-shaped elastic sheet 2 away from the touchpad 1, the lifting degree of the two ends of the strip-shaped elastic sheet 2 will be higher, the pressing force of the pressing side will be larger, and the extension length of the strip-shaped elastic sheet 2 as a whole will be shorter; if the pushing mechanism 3 pushes the middle part of the strip-shaped elastic sheet 2 close to the touchpad 1, the lifting degree of the two ends of the strip-shaped elastic sheet 2 will be smaller, the pressing force of the pressing side will be smaller, and the extension length of the strip-shaped elastic sheet 2 as a whole will be longer.

[0036] The middle part of the strip-shaped elastic sheet 2 in the touchpad assembly provided by the embodiment is arched downward, and the two ends are respectively in abutment with the lower surface of the pressing side of the touchpad 1. The user can push the middle part of the strip-shaped elastic sheet 2 along the touch direction perpendicular to the touchpad 1 by the pushing mechanism 3 to change the extension length of the strip-shaped elastic sheet 2, so as to adjust the pressing force of the pressing side of the touchpad 1, thereby meeting the needs of different customers for different pressing forces.

[0037] As shown in Figure 4 and Figure 7 In some embodiments, a baffle 4 is arranged between the pressing side of the touchpad 1 and the strip-shaped elastic sheet 2. The baffle 4 can be fixed on the upper cover 5 or integrally arranged with the upper cover 5. The baffle 4 is spaced apart from the two limiting sliding grooves 41 along the length direction of the strip-shaped elastic sheet 2. The two ends of the strip-shaped elastic sheet 2 are respectively arranged in the two limiting sliding grooves 41, and the middle part is located between the two limiting sliding grooves 41 and below the baffle 4. In this way, when the strip-shaped elastic sheet 2 is pushed to move, the limiting sliding grooves 41 can ensure that the two ends of the strip-shaped elastic sheet 2 extend or retract along the length direction thereof.

[0038] As shown in Figure 5 In some embodiments, two downward extending limiting parts 42 are further arranged between the two limiting sliding grooves 41 of the baffle 4. The two limiting parts 42 are located on both sides of the middle part of the strip-shaped elastic sheet 2, that is, the middle part of the strip-shaped elastic sheet 2 is located between the two limiting parts 42, so that when the middle part of the strip-shaped elastic sheet 2 moves, it will not deviate to both sides or overturn, and it can be ensured that it moves perpendicular to the touch direction of the touchpad 1. The shape of the limiting part 42 is not limited in the present application.

[0039] In some embodiments, each of the two limiting portions 42 has a plurality of protrusions (not shown in the figure) on one side of its opposite side along the vertical direction (i.e., the touch direction), and the protrusions on the two limiting portions 42 correspond one-to-one, protruding towards each other, and have smooth surfaces. Because the strip spring 2 has a certain elasticity, the middle part of the strip spring 2 will rub against the surface of the protrusions when it moves. When the strip spring 2 is fixed at a certain height, both sides of the strip spring 2 can be respectively engaged between the corresponding two protrusions of the two limiting portions 42 to achieve positioning, thereby ensuring the stability of the strip spring 2.

[0040] Continue as Figure 5 As shown, the portion of the baffle 4 located between the two limiting parts 42 is provided with a spring hole 43, and a compression spring 34 is provided inside the spring hole 43. (See Figure 1) Figure 2 One end of the compression spring 34 abuts against the bottom surface of the spring hole 43, and the other end abuts against the upper surface of the middle part of the strip spring 2, thereby applying a downward force to the strip spring 2. In this way, the downward force of the compression spring 34 can make the strip spring 2 more accurately positioned.

[0041] like Figure 2 As shown, the pushing mechanism 3 in this embodiment mainly includes a transmission component 33 and a rotating component 31. The transmission component 33 is located below the strip-shaped spring 2 and is fixedly connected to the middle part of the strip-shaped spring 2. The rotating component 31 is connected to the transmission component 33. The rotation of the rotating component 31 can drive the middle part of the strip-shaped spring 2 to move and deform in the touch direction through the transmission component 33, so that the two ends of the strip-shaped spring 2 extend or retract along its length direction, respectively.

[0042] like Figure 2 As shown, in some embodiments, the rotating member 31 is located below the transmission member 33. The rotating member 31 can be limited in the Z-axis direction (i.e., the vertical direction) so that it can only rotate on its own axis. The rotating member 31 is a rotating column, and the transmission member 33 is a threaded column. The top end face of the rotating member 31 extends upward to form a protrusion 32. The protrusion 32 has a threaded hole along its axial direction. The bottom of the threaded column is threadedly connected to the threaded hole on the protrusion 32, and the top of the threaded column is fixedly connected to the middle of the strip spring 2. In this way, the rotation of the rotating column can drive the threaded column and the strip spring 2 to move.

[0043] Furthermore, such as Figure 4 and Figure 6As shown, the shell 7 of the electronic device includes an upper cover 5 and a lower shell 6, the mounting groove is arranged on the upper cover 5, and the lower shell 6 is provided with a stepped hole 61 penetrating to the mounting groove, which is divided into an upper stepped hole and a lower stepped hole from top to bottom. In some embodiments, the bottom of the rotating column is arranged in the upper stepped hole, the protruding part 32 of the top of the rotating column extends into the two limiting parts 42 on the baffle 4, and the free ends of the two limiting parts 42 respectively abut against the top end face of the rotating column, see Figure 7 . In this way, the limiting parts 42 on the baffle 4 and the stepped hole 61 on the lower shell 6 can realize the axial positioning of the rotating column.

[0044] As shown in Figure 6 , the lower stepped hole in the stepped hole 61 in the embodiment penetrates the lower shell 6, and the bottom end face of the rotating column is provided with a cross-shaped groove or a straight-line-shaped groove. In this way, the user can control the rotation of the rotating column by using a screwdriver at the bottom of the shell 7, thereby realizing the adjustment of the pressing force degree of the pressing side of the touchpad 1.

[0045] Further, in the embodiment, one support column 62 is arranged on each side of the upper stepped hole 61 of the lower shell 6, and the top of the support column 62 extends to the lower side of the end of the strip-shaped elastic sheet 2 or the region between the end and the middle part without contacting them, so as to avoid that the user presses too hard, thereby causing the strip-shaped elastic sheet 2 to be deformed too much.

[0046] Some other embodiments of the present application also provide an electronic device, which includes a system end and a display end, and the shell of the system end is provided with the touchpad assembly of any one of the above embodiments.

[0047] The above description is intended to be illustrative rather than limiting and many modifications, changes, substitutions, and alterations can be made by one of ordinary skill in the art without departing from the scope of the disclosure. Moreover, the above examples (or one or more aspects thereof) can be used in combination with each other and considered to be combinable with each other in various combinations or permutations.
