Problems solved by technology

However, under the current trend of all kinds of electronic devices being designed to be thinner, lighter and smaller, due to the thinning of the circuit board and other stacked layers, the corners of the touch panel device have insufficient rigidity.
In addition, the design of the fixed side of the existing stacked touchpad device has a great impact on the overall production rate
If the tolerance of the process and materials is too large, it will cause poor product stability, for example, it is easy to generate noise during use

Abstract

A touchpad device comprises a base plate, at least one support plate, a circuit board, a first extension structure and a second extension structure. The base plate is configured to be secured to the housing. The support plate is coupled to the bottom plate and is configured to swing relative to the bottom plate. The circuit board is attached to the side, away from the bottom plate, of the supporting plate. The first extension structure is arranged on the bottom plate and extends towards the supporting plate. The second extension structure is provided with the supporting plate and extends towards the bottom plate. The first extension structure partially extends to the side, close to the supporting plate, of the second extension structure, or the second extension structure partially extends to the side, close to the bottom plate, of the first extension structure.

Description

technical field [0001] The invention relates to a touch panel device. Background technique [0002] With the advancement of technology, touch panel devices have been widely used in various portable electronic products such as notebook computers, tablet computers, and personal digital assistants. The touchpad device senses the movement of the user's fingers and makes the pointer move correspondingly synchronously, so the touchpad device can replace the mouse as an input and operation device. [0003] In order to provide the user with the function of generating a click command by pressing, the movement principle of the existing touch panel device is usually to adopt the structural form of a hinge. Among them, the overall rigidity of the existing stacked touch panel device mainly comes from the circuit board itself, or the circuit board or the bottom needs to be equipped with relatively hard materials, such as glass or metal. However, under the current trend that various elec...
