Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a click-pad assembly and positioning structure. Background Technology

[0002] Click-pad positioning devices commonly include positioning barriers and double positioning barriers. Both are assembled using a gate-type positioning method. However, existing positioning methods are prone to shaking or interference jamming after assembly, making them difficult to assemble, resulting in low production capacity and inconvenient operation. Furthermore, the die-cutting precision is difficult to control, making it hard to manage dimensional accuracy and easily causing dimensional deviations. The positioning points are also difficult to assemble, resulting in low production capacity, inconvenient operation, and inaccurate positioning mechanism dimensions, which can easily cause shaking abnormalities. Utility Model Content

[0003] Purpose of the utility model: The present utility model aims to provide a click-pad assembly positioning structure that can avoid abnormal shaking caused by excessive gaps.

[0004] Technical solution: This utility model discloses a click-pad assembly positioning structure, including a glass plate, a PCB board, conductive foam, adhesive backing, a plastic middle plate, a balance bar, supporting iron parts, and conductive cloth. The supporting iron parts and the plastic middle plate are connected by a pressing positioning method. The supporting iron parts are provided with positioning hooks, and the plastic middle plate is provided with a retaining wall. During assembly, the retaining wall of the plastic middle plate locks the positioning hooks on the supporting iron parts to achieve X-axis and Y-axis limiting and positioning.

[0005] Furthermore, the supporting iron component and the plastic middle plate are positioned using a bridge-type positioning method to achieve Z-axis direction limiting.

[0006] Furthermore, the supporting iron piece is provided with a small arch bridge, and the plastic middle plate is provided with a hook. The hook includes an upper hook and a lower hook located on both sides of the small arch bridge of the supporting iron piece. During assembly, the upper hook and the lower hook are opened so that the small arch bridge of the supporting iron piece is locked into the hook of the plastic middle plate, thereby achieving Z-axis direction limiting.

[0007] Furthermore, the positioning hook serves as a retaining wall that supports the iron component folded up at 90°.

[0008] Furthermore, the retaining wall on the plastic plate has a chamfer.

[0009] Furthermore, the plastic middle plate includes Tiance plastic middle plate and Dice plastic middle plate.

[0010] Furthermore, the adhesive backing includes adhesive backing for the Tiance mid-plate and adhesive backing for the Dice mid-plate.

[0011] Beneficial effects: Compared with the prior art, this utility model has the following significant advantages: 1. The supporting iron positioning barrier is formed by one-time die-cutting, which makes the size control more precise and less prone to variation; 2. The positioning mechanism between the supporting iron and the plastic middle plate of this structure has more precise size control and the reserved gap is smaller, which can avoid abnormal shaking caused by excessive gap; 3. When assembling this structure, the supporting iron and the middle plate slide against the inclined surface when pressed together, which makes assembly convenient. Attached Figure Description
