[0036] A bottom plate 1 is provided with a tactile switch 2.

[0037] An elastic bearing frame 3 comprises a spring sheet 31 detachably connected with the bottom plate 1 and a fixed frame 32 supported by the spring sheet 31 in a horizontal state.

[0038] A touch panel is arranged on the upper surface of the fixed frame 32.

[0039] In order to overcome the problem of high cost and difficulty of overall replacement of the touchpad when the elasticity of the elastic support is weakened in the prior art, the computer touchpad of the present application is provided. Unlike the prior art, in the present application, the bottom plate 1 is used as the bearing component of the touchpad, rather than directly using the bottom plate 1 as the elastic support to provide elastic force as in the prior art. In the present application, the elastic bearing frame 3 is used as the elastic component to provide displacement function for the touchpad, and the elastic bearing frame 3 includes the elastic sheet 31 and the fixed frame 32, wherein the elastic sheet 31 is detachably connected with the bottom plate 1, and the fixed frame 32 supports the touch panel. When the elastic force of the elastic sheet 31 is weakened with the increase of the number of uses, only the elastic bearing frame 3 needs to be replaced, and overall replacement is not required, thereby reducing the maintenance cost compared with the prior art. Further, since the elastic sheet 31 of the elastic bearing frame 3 is detachably connected with the bottom plate 1, it is easier to replace, thereby reducing the maintenance difficulty compared with the prior art.

[0040] In addition, unlike the prior art which needs to process the bottom plate 1 as an elastic support, the computer touchpad of the present application uses the elastic sheet 31 as an elastic component, and the overall structure is simpler and has lower processing difficulty compared with the prior art, so the production cost is lower and the production yield is higher.

[0041] Further, in the present application, the elastic bearing frame 3 includes two elastic sheets 31, and the two elastic sheets 31 are symmetrically arranged on the bottom plate 1. As shown in the figure, the two elastic sheets 31 are arranged on the two sides of the bottom plate 1, and the fixed frame 32 can be in a horizontal state by symmetrically arranging the two elastic sheets 31, so that the touch panel supported thereby is kept horizontal.

[0042] Further, the two elastic sheets 31 are adhered to the bottom plate 1 by 3M glue, and the touch panel is adhered to the upper surface of the fixed frame 32 by 3M glue. As described above, the elastic sheet 31 and the bottom plate 1 are detachably connected, and in the present application, the elastic sheet 31 is adhered to the bottom plate 1 by 3M glue, and the 3M glue has hot melting property, which can be dissolved by hot air blowing during maintenance.

[0043] According to one embodiment of the present application, as Figure 4As shown, the elastic sheet 31 comprises a first flat plate 311 connected with the bottom plate 1, a second flat plate 312 connected with the fixed frame 32, and an elastic strip 313 connecting the first flat plate 311 and the second flat plate 312, and the elastic strip 313 is arranged in an inclined manner. The first flat plate 311 is provided with a connecting through hole 314, and the bottom plate is provided with a fixed through hole 11 at a corresponding position, and a connecting bolt passes through the connecting through hole 314 and the fixed through hole 11 to threadedly connect the first flat plate 311 and the bottom plate 1. As shown, in order to ensure the stability of the connection between the elastic sheet 31 and the bottom plate 1, the elastic sheet 31 is in a zigzag shape as a whole in the embodiment, the first flat plate 311 is connected with the bottom plate 1, the second flat plate 312 is connected with the fixed frame 32, and the elastic strip 313 is connected with the first flat plate 311 and the second flat plate 312 in an inclined manner. Further, the fixed through hole 11 is formed in the bottom plate 1, and the connecting through hole 314 is formed in the first flat plate 311, and the first flat plate 311 and the bottom plate 1 are connected by a bolt. In the embodiment, the first flat plate 311 and the bottom plate 1 can be first bonded by 3M glue and then connected and reinforced by a bolt, or connected by a bolt alone. The second flat plate 312 is connected with the bottom of the fixed frame 32, and further, the second flat plate 312 and the fixed frame 32 can be connected by laser welding or 3M bonding.

[0044] Further, the elastic sheet 31 comprises two elastic strips 313, and the two elastic strips 313 are symmetrically arranged at two ends of the first flat plate 311. By arranging two elastic strips 313 respectively at two ends of the first flat plate 311, on the one hand, the stability of support can be improved, and on the other hand, the pressing position distribution of the touch panel can be more extensive, and no matter where the pressing position is, it can be recognized.

[0045] Further, in the embodiment, the second flat plate 312 is formed with a flange 315 at each end. As shown, the flanges 315 at the two ends of the second flat plate 312 are used to hold the bottom of the keyboard surface shell during installation, so as to prevent the touch panel from being warped due to excessive displacement of one-sided pressing.

[0046] Further, as shown, Figure 4 In the embodiment, the bottom plate 1 further comprises fixed ears 13 arranged on both sides, and mounting holes 12 are formed in the fixed ears 13. The computer touch pad of the utility model is mounted to the reserved position of the computer shell through the mounting holes 12 of the fixed ears 13.

[0047] According to an embodiment of the utility model, in the embodiment, the touch panel comprises a touch pad PCB 4 and a protection plate 5 arranged on the upper surface of the touch pad PCB 4. The protection plate 5 is a glass plate.
