Description

Technical Field

[0001] The utility model relates to an LED headlight module for an electric vehicle with an improved protection level. Background Art

[0002] During the production process of existing LED headlight modules for two-wheeled electric vehicles, the electronic components on the PCB board are not glued, and the sealing of the lamp shell of the headlight module is poor, making the electronic components on the PCB board not moisture-proof and easily damaged; some car companies use three-proof paint on the surface of the electronic components to deal with the moisture-proof problem, but due to the scattered layout of the electronic components, the protection performance is still not ideal. Summary of the invention

[0003] In view of the shortcomings existing in the above problems, the utility model provides an LED headlight module for electric vehicles with improved protection level.

[0004] To achieve the above-mentioned purpose, the utility model provides an LED headlight module for an electric vehicle with an improved protection level, including a PCB board, on which a plurality of electronic components and LED lamp beads are arranged in a concentrated manner. The PCB board is also provided with a glue potting bracket, which forms a seal with the PCB board and surrounds the plurality of electronic components arranged in a concentrated manner. By pouring an appropriate amount of glue into the glue potting bracket, protection of the plurality of electronic components is achieved.

[0005] Furthermore, a positioning hole is formed on the PCB board, a positioning column is formed on the glue-filling bracket, and the positioning hole is used to receive the positioning column.

[0006] Furthermore, the glue-potting bracket is rectangular, and the number of the positioning columns and the number of the positioning holes are both two.

[0007] Furthermore, during assembly, the bottom of the glue-filling bracket is dip-coated with conformal coating to ensure the sealing between the glue-filling bracket and the PCB board after assembly.

[0008] Furthermore, a step surface is formed on the glue-pouring bracket.

[0009] Furthermore, the PCB board is also configured with a small lens and a large lens.

[0010] The beneficial effects of the utility model compared with the prior art are:

[0011] 1. Arrange multiple electronic components in a centralized manner. At the same time, the centralized electronic components are surrounded by the glue-filling bracket. By filling glue into the glue-filling bracket, effective protection of the electronic components is achieved, thereby improving the IP level of the LED headlight module.

[0012] 2. A step surface is also formed on the glue-filling bracket. After the glue is poured in, the glue solidifies and adheres to the electronic components, which can reduce the possibility of the glue-filling bracket falling off. BRIEF DESCRIPTION OF THE DRAWINGS
