[0025] Reference Figure 1-4 , an embodiment of the present application is proposed, in which the automobile door light includes a shell 10 and a circuit board 20, the upper end of the shell 10 is open, and the shell 10 is integrally formed with a mounting structure 30, a fixing structure 40, a light emitting portion 50 and a wiring harness lead-out structure 60 using a translucent material, the shell 10 is mounted on the automobile decorative panel through the fixing structure 40, the circuit board 20 is mounted in the shell 10 through the mounting structure 30, an LED light source 21 is provided at the lower end of the circuit board 20, the light emitting portion 50 is distributed at the lower end of the shell 10, the wiring harness lead-out structure 60 is arranged on the side wall of the shell 10 and is connected to the inside of the shell 10, and the pins of the circuit board 20 are led out through the wiring harness lead-out structure 60.

[0026] The automobile door light consists of only two parts: a housing 10 and a circuit board 20. The housing 10 is made of a transparent material in one piece, which is convenient for production.

[0027] When assembling the automobile door lamp, the circuit board 20 can be directly installed in the housing 10, which reduces the number of assembly parts and facilitates assembly.

[0028] The fixing structure 40 includes a boss 41 arranged at the lower end of the shell 10 and clamping feet 42 arranged on two opposite sides outside the shell 10. When installing the car door light, the upper end of the shell 10 is inserted into the car decorative panel 70, and the circumferential side wall of the car interface is clamped between the boss 41 and the clamping feet 42 to complete the installation of the door light.

[0029] The shell 10 is made of atomized material, and / or a light-mixing microstructure is integrally formed on the light-emitting portion 50, so that the car door light has a uniform light effect. The shell 10 is made of a light-transmitting material. In another embodiment, the shell 10 can also use a surface treatment process to make its light-emitting portion 50 have a uniform light effect.

[0030] Specifically, the mounting structure 30 includes a first limit block 31 arranged on the inner walls on both sides of the shell 10. The inner wall of the shell 10 is also provided with a second limit block 32 below the first limit block 31. The circuit board 20 is clamped between the first limit block 31 and the second limit block 32.

[0031] According to the above content, further, the first limiting block 31 is a wedge-shaped block, and the slope 311 of the wedge-shaped block faces upward. When installing the circuit board 20, the circuit board 20 is placed along the slope 311 of the wedge-shaped block to facilitate installation.

[0032] Furthermore, the wiring harness lead-out structure 60 is a lead-out channel, disposed at the upper end of the side wall of the housing 10. The upper end of the second stopper 32 is provided with a stepped surface 321 for limiting the position of the circuit board 20. This stepped surface 321 matches the height of the lead-out channel. As shown in the accompanying drawings, when the circuit board 20 is clamped between the first stopper 31 and the stepped surface 321, it is positioned through the lead-out channel via pins, further ensuring that the circuit board 20 can be stably installed within the housing 10.

[0033] According to the above content, further, the upper end of the second limit block 32 is provided with a slope 322, and the slope 322 is inclined downward to the step surface 321 toward the side inside the shell 10. When the circuit board 20 and the shell 10 are assembled, the circuit board 20 is pressed so that the circuit board 20 moves downward along the slope 322 and the wedge block and is stuck under the first limit block 31. The slope 322 can prevent the circuit board 20 from tilting up when being pressed, ensuring that the circuit board 20 can be smoothly stuck between the first limit block 31 and the step surface 321.

[0034] A light-shielding paint layer is provided on the outer wall of the shell 10, so that the light emitted by the LED light source 21 in the shell 10 can only be emitted from the lower end of the shell 10, avoiding light from the side of the shell 10 causing the driver and passengers to observe from the gap between the car decorative panel 70 and the shell 10, thereby ensuring the light effect of the door light.

[0035] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
