Description

Technical Field

[0001] The invention relates to the technical field of panels, and in particular to a display panel assembly with a spring that is not easy to fall off. Background Art

[0002] The panel assembly of the existing display panel assembly needs to be close to the glass panel so that the displayed font can be clear. In order to ensure that the panel assembly can fit the glass, a spring is needed to push the panel assembly onto the glass panel. In the prior art, multiple springs are installed on the corresponding spacer columns respectively, and the two are installed together on the PCBA board, and then assembled with the main bracket. The disadvantages of the existing solution are: the springs and spacer columns are not easy to install and the cost is high; each spacer column needs to be installed with the main bracket, and the spacer column is shaking, which makes it difficult to align and the production efficiency is low. Summary of the invention

[0005] Furthermore, an upper connecting ear plate and a lower connecting ear plate are respectively formed at the upper and lower ends of the glass panel fixing piece. The upper connecting ear plate is fixedly connected to the glass panel by gluing, and the lower connecting ear plate is locked to the main frame by screws.

[0006] Furthermore, a glass panel fixing piece is respectively installed between the glass panel and two side edges of the main frame.

[0007] Furthermore, a plurality of reflector buckles are dispersedly provided on the reflector, and the reflector is connected and fixed together with the PCBA board buckles through the reflector buckles.

[0008] Furthermore, the reflector cover is provided with an elastic clip extending downward, the PCBA board is provided with a through hole, and the main bracket is provided with a limit hole. The elastic clip passes through the through hole and is connected with the limit hole of the main bracket to prevent the panel assembly from being excessively lifted by the spring and detached from the main bracket.

[0009] Furthermore, two elastic buckles are provided on the reflector.

[0010] Furthermore, the spring body is a tower-shaped spring structure that is larger at the top and smaller at the bottom.

[0011] Furthermore, the elastic clamping joint and the spring body are an integrally bent structure.

[0012] Furthermore, the elastic snap connector includes a snap-fitting portion for snap-fitting with the snap-fitting hole of the PCBA board, and a guide portion is formed at the upper end of the snap-fitting portion.

The first straight section, the first vertical section and the first bend section form a left half snap-in structure, and the second bend section, the second vertical section and the horizontally arranged end free section form a right half snap-in structure. The left half snap-in structure and the right half snap-in structure cooperate with each other to form a snap-in portion adapted to the snap-in hole of the PCBA board, and the first inclined guide section and the second inclined guide section cooperate with each other to form a guide portion that can be elastically retracted.

[0014] Furthermore, the elastic clamping joint is in a circular curved shape, and the end of the elastic clamping joint is a free end structure that can be bent and deformed under pressure.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] In the display panel assembly with a spring that is not easy to fall off described in the present invention, the glass panel and the main body bracket are connected and fixed to each other at intervals through a glass panel fixing piece, and the spring piece includes a spring body and an elastic clamping joint arranged at the upper end of the spring body. The upper end of the spring piece is clamped and fixed to the clamping hole of the PCBA board through the elastic clamping joint, and the lower end of the spring body is directly elastically abutted against the main body bracket. In this way, the panel assembly can be stably attached to the glass panel without using a spacer column structure. At the same time, the use of the spacer column is omitted, which can save production costs on the one hand, and simplify the assembly process on the other hand. There is no problem of difficult assembly of the spring piece and the spacer column, and difficult correspondence between the spacer column and the panel assembly and the main body bracket, which effectively improves the assembly efficiency.
