Touch pad module

a technology of touch pad and module, which is applied in the field of touch pad module, can solve the problems of insufficient pressing rigidity of corners of the movable end (i, two ends away from the restoring member) of the touch pad module, and the conventional touch pad module has no structure to support the touch panel and the circuit board, so as to reduce shaking, increase the overall rigidity of the linkage assembly, and reduce deformation

AI Technical Summary

Benefits of technology

The present invention relates to a touch pad module that reduces deformation and shaking during use, improves tactile feedback, and reduces the required installation space. The module includes an elastic plate and a supporting plate between the touch panel and the frame, which work together to shorten the distance between the touch panel and the frame, resulting in a more rigid linkage assembly and a better feel when pressing the touch pad.

Problems solved by technology

However, the conventional touch pad module has no structure to support the touch panel and the circuit board except for the frame.
Therefore, the corners of the movable end (i.e., the two ends away from the restoring member) of the touch pad module will have insufficient pressing rigidity.

Abstract

The present invention discloses a touch pad module, which includes a touch panel, a frame and a linkage assembly. The frame is disposed under the touch panel. The linkage assembly is disposed between the touch panel and the frame. The linkage assembly includes an elastic plate and supporting plate. The elastic plate has a first portion, a second portion and a third portion. The second portion is located between the first portion and the third portion, the first portion is connected to the touch panel, and the third portion is connected to the frame. The supporting plate is correspondingly disposed on the second portion of the elastic plate.

Description

BACKGROUND1. Technical Field[0001]The present invention relates to a touch pad module.2. Description of the Related Art[0002]Notebook computers are often equipped with a touch pad module to allow users to operate the notebook computer by touch (using a finger to press or slide on the touch pad) to replace the function of the mouse.[0003]Generally speaking, the main components of the touch pad module comprise, from top to bottom, a touch panel, a circuit board and a frame in sequence. The two opposite sides of the touch panel are a fixed end and a movable end, respectively. Specifically, one side of the touch panel can be fixed to the frame or directly fixed to the casing of the notebook computer, while the other unfixed side is a movable end. In addition, the touch panel module has a restoring member (e.g., a dome sheet) disposed on the frame and located in the middle position of the movable end. When the user presses the movable end, the touch panel can move up and down and trigger...
