Description

Technical Field

[0001] This utility model relates to the field of computer equipment, and in particular to a lightweight touchpad module. Background Technology

[0002] Traditional touchpads consist of a glass touch panel and a PCB board mounted beneath it. Since the thickness of the existing PCB board and glass touch panel has reached the limits of current manufacturing processes, it's impossible to further reduce the overall thickness from the perspective of individual components. However, with increasing competition in the laptop market, the pursuit of lighter and thinner designs has become a consensus in product design. Therefore, it is necessary to continuously optimize the existing touchpad structure to further reduce the overall thickness of the touchpad to meet market demands. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a lightweight touchpad module that can further reduce the thickness of the touchpad module.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lightweight touchpad module is provided, comprising: a glass PCB substrate, an adhesive backing plate, a reinforcing plate, and a supporting base plate. The glass PCB substrate, adhesive backing plate, reinforcing plate, and supporting base plate are stacked together from top to bottom. The glass PCB substrate is divided into three layers from top to bottom: a printing layer, a glass layer, and a PCB circuit layer. The adhesive backing plate, reinforcing plate, and supporting base plate are all provided with cable routing grooves. The two sides of the supporting base plate are simultaneously folded upward to form a folded edge structure. The two sides of the reinforcing plate are fixed to the folded edge structure on the corresponding sides.

[0005] In a preferred embodiment of this utility model, the adhesive backing board includes an adhesive backing board body and a spring-loaded adhesive strip. The outer contour of the reinforcing plate is the same as that of the adhesive backing board body. A protective plate is installed below the spring-loaded adhesive strip. The protective plate is fixedly connected to the folded edge structure on the corresponding side of the supporting base plate. A first spring-loaded insertion hole is provided in the middle of the spring-loaded adhesive strip, and a second spring-loaded insertion hole is provided in the middle of the protective plate. The first and second spring-loaded insertion holes are identical in shape and communicate with each other. The outline of the adhesive backing board body is determined by the PCB circuit distribution shape on the glass PCB substrate.

[0006] In a preferred embodiment of the present invention, the cable clearance grooves on the adhesive backing plate, the reinforcing plate and the supporting base plate are respectively the first clearance groove, the second clearance groove and the third clearance groove. The first clearance groove, the second clearance groove and the third clearance groove are each composed of two symmetrically distributed grooves, and the groove contours of the three clearance grooves are the same and they are connected vertically.

[0007] The beneficial effects of this utility model are: Based on the existing touch panel composition structure, this utility model integrates the glass substrate of the touch panel with the corresponding PCB board, and then reorganizes the support structure on the back according to the integrated substrate, thereby reducing the overall thickness of the entire touch panel module and further meeting the requirements of laptops to be thinner and lighter.

[0014] Please see Figure 1 and Figure 2 The embodiments of this utility model include:

[0015] A lightweight touchpad module includes: a glass PCB substrate 1, an adhesive backing board 2, a reinforcing plate 3, and a supporting base plate 5. The glass PCB substrate 1, adhesive backing board 2, reinforcing plate 3, and supporting base plate 5 are stacked sequentially from top to bottom. The glass PCB substrate 1 consists of three layers from top to bottom: a printed layer 102, a glass layer 101, and a PCB circuit layer 103. The adhesive backing board 2, reinforcing plate 3, and supporting base plate 5 are all provided with cable routing grooves. The connector cable clearance slots on board 2, reinforcing board 3, and supporting base plate 5 are respectively the first clearance slot 203, the second clearance slot 301, and the third clearance slot 501. The first clearance slot 203, the second clearance slot 301, and the third clearance slot 501 are each composed of two symmetrically distributed slots. The three clearance slots have the same outline and are vertically connected. The two sides of the supporting base plate 5 are simultaneously folded upward to form a folded edge structure 502. The two sides of the reinforcing board 3 are fixed to the folded edge structure 502 on the corresponding sides. In this way, the supporting base plate supports the reinforcing board and abuts against the underside of the adhesive backing board, forming the support structure of the glass PCB substrate. Moreover, the entire support structure provides dedicated clearance space for the connector cables connecting to the PCB circuit layer, avoiding the connector cable connections occupying extra space and further improving the overall compactness of the structure.

[0016] The adhesive backing board 2 includes an adhesive backing board body and a spring-loaded adhesive strip 201. The outer contour of the reinforcing plate 3 is the same as that of the adhesive backing board body. The contour of the adhesive backing board body is determined by the circuit distribution shape of the PCB circuit layer 103 on the glass PCB substrate 1. A protective plate 4 is installed below the spring-loaded adhesive strip 201. The protective plate 4 is fixedly connected to the folded edge structure 502 on the corresponding side of the supporting base plate 5. A first spring-loaded contact hole 202 is provided in the middle of the spring-loaded adhesive strip 201, and a second spring-loaded contact hole 401 is provided in the middle of the protective plate 4. The first spring-loaded contact hole 202 and the second spring-loaded contact hole 401 have the same shape and are interconnected. In this way, the spring-loaded contact of the touch panel is supported by the protective plate and the supporting base plate, and a dedicated spring-loaded contact groove is provided, reducing the space occupied during the spring-loaded contact installation process.
