Description

Technical Field

[0001] This utility model relates to the field of automotive lighting assembly technology, and in particular to an installation structure for an automotive taillight interactive screen circuit board. Background Technology

[0002] When automotive headlight circuit boards are installed and secured internally, they require mounting structures to attach to surrounding components. Currently, screws, rivets, and clips are the primary methods used, requiring significant installation space. Because the center of the automotive taillight interactive screen circuit board contains a dense array of LEDs, it's impossible to arrange mounting structures there. The only solution is to increase the circuit board's size and then incorporate screws, rivets, and clips at the edges. This requires substantial installation space, and OEMs, for aesthetic reasons, don't allocate much space for these structures. Therefore, achieving both a secure and stable installation without compromising the vehicle's appearance presents a significant challenge for circuit board installation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a circuit board mounting structure for automotive taillight interactive screens. The mounting structure is arranged on the back of the LED circuit board and does not need to occupy the appearance space.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An automotive taillight interactive screen circuit board mounting structure includes a lamp cover and a housing that are assembled together. A bracket is installed inside the housing, and a decorative ring is provided at the front of the bracket.

[0006] An LED circuit board is provided between the decorative ring and the bracket. Several welding nuts are provided on the back side of the LED circuit board near the bracket. Several locking screws corresponding to the welding nuts are installed on the bracket. The LED circuit board is installed and fixed with the bracket by the locking cooperation of the welding nuts and locking screws.

[0007] Furthermore, the welding nut has a groove pattern formed on the end face near the LED circuit board.

[0008] Furthermore, the upper surface of the welding nut near the LED circuit board is tin-plated.

[0009] Furthermore, the welding nut is made of copper alloy or carbon steel.

[0010] Furthermore, a limiting structure with a corresponding welded nut is provided on the front side of the bracket, and the welded nut is aligned and limited with the limiting structure.

[0011] Furthermore, the LED circuit board has multiple LED light sources located on the front side near the decorative ring.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] 1. This utility model securely mounts the LED circuit board to the front of the bracket by welding a welding nut to the back of the LED circuit board and then locking it with a locking screw mounted on the bracket. This eliminates the need for mounting structures on the front and edges of the LED circuit board, reducing the overall size, saving internal space, and not affecting the external shape, making it easier to meet the design requirements of the OEM.

[0014] 2. This utility model increases the welding area and welding strength by creating a shaped groove pattern on the end face of the welding nut near the LED circuit board and tin-plating the surface, thereby increasing the fixing reliability and ensuring the installation stability with surrounding components.

[0018] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] like Figure 1 , 2 As shown, this embodiment provides a circuit board mounting structure for an automotive taillight interactive screen, which mainly consists of a lampshade 1, a decorative ring 2, a housing 8, a bracket 5, and an LED circuit board 4. The lampshade 1 is mounted on the front side of the housing 8, forming an internal accommodating space. The bracket 5 is positioned rearward within the accommodating space and is fixed to the inner wall of the housing 8. The decorative ring 2 is mounted on the front of the bracket 5. The LED circuit board 4 is positioned between the decorative ring 2 and the bracket 5, and multiple LED light sources 3 are arranged on the front side of the LED circuit board 4 near the decorative ring 2 for emitting light.

[0020] To save internal space, two welding nuts 6 are installed on the rear side of the LED circuit board 4 near the bracket 5. Two locking screws 7 corresponding to the welding nuts 6 are mounted on the bracket 5 from the rear to the front. The two locking screws 7 lock into the two welding nuts 6, thus fixing the LED circuit board 4 to the bracket 5. This eliminates the need for mounting structures on the front and edges of the LED circuit board 4, reducing the overall size, saving internal space, not affecting the external appearance, and making it easier to meet the design requirements of the OEM.

[0021] To improve installation reliability, in this embodiment, the welding nut 6 has a groove 9 formed on the end face near the LED circuit board 4, and the upper surface of the end face of the welding nut 6 near the LED circuit board 4 is tin-plated. The welding nut 6 is made of copper alloy or carbon steel. This increases the welding area and welding strength, thereby increasing the fixation reliability and ensuring the installation stability with surrounding components.

[0022] In addition, to make the installation of LED circuit board 4 quicker and more convenient, a limiting structure 50 with a corresponding welding nut 6 is provided on the front side of the bracket 5 in this embodiment. The welding nut 6 is aligned with the limiting structure 50, so that alignment can be quickly performed during installation, improving installation efficiency.
