A refrigerator lighting structure and its assembly and positioning method

Abstract

The invention discloses a refrigerator lighting structure and an assembly and positioning method thereof. The structure comprises a pre-embedded box, an LED lamp board arranged on the pre-embedded box, and a lampshade arranged on the outside of the LED lamp board. The pre-embedded box is fixedly arranged on the On the inner tank, the lampshade is connected and fixed with the inner tank. By connecting and fixing the lampshade and the inner container, there is no direct assembly relationship between the lampshade and the pre-embedded box, so the molding thickness of the inner container does not affect the assembly of the lampshade, which improves the assembly efficiency and avoids the failure of the lampshade to fit and cause the box to be scrapped. problems and reduce production costs; at the same time, the position of the pre-embedded box is effectively positioned by setting positioning ribs to ensure the relative accuracy of the position of the LED light board to achieve correct lighting of the LED light board.

Problems solved by technology

[0003] Traditional incandescent lighting is gradually being eliminated on refrigerators. Due to the compact structure and small footprint of LEDs, the assembly structure required for them is also more delicate. The assembly structure of traditional LED lights is complex, and usually requires assembly fixtures, and the refrigerator liner is in a molded state. It is closely related to assembly. The uneven thickness of the molded liner leads to difficulties in assembly. The pre-embedded box for LED lights is a device for pre-embedding and foaming LED lights. The existing LED pre-embedded boxes are usually assembled on both sides. The adhesive tape fixes the pre-embedded box on the refrigerator liner 14, and the LED light board 12 is fixed on the pre-embedded box. When assembling, the pre-embedded box cover, namely the LED lampshade 13, is fixed on the pre-embedded box 11 with a hook. (like figure 1 As shown), the assembly operation is complicated, and once the refrigerator inner liner is formed too thick, it will be difficult to assemble, resulting in a decrease in assembly efficiency, and there may also be a situation where the lampshade and the embedded box cannot be assembled. Cause the box to be scrapped and increase the production cost

[0004] In addition, in the traditional technology, the lampshade is fixedly connected to the embedded box, and the offset of the position of the lampshade will affect the offset of the lighting position of the LED lamp. Achieving Correct Illumination of LEDs
