Description

Technical Field

[0001] The utility model belongs to the technical field of headlight sockets and relates to a headlight socket structure for electric vehicles with good heat dissipation performance. Background Art

[0002] With the widespread use of LED lights, most electric vehicle headlights have also gradually adopted LED technology. LED light sources not only have a long service life, but also have high luminous efficiency, low radiation, and low power consumption. Therefore, their use in electric vehicles is becoming increasingly popular. The heat dissipation devices of existing LED car headlights all use base-type radiators, which are made of stacked aluminum sheets. The disadvantage of this approach is that for the headlight, the radiator is located inside and does not touch the outside of the headlight base. This causes the heat to be concentrated inside the lampshade. When the heat is concentrated, the heat dissipation performance will decrease. In addition, when it is installed on the electric vehicle during use, the connection of the wiring harness is scattered and the connection strength of the wiring harness terminals cannot be guaranteed. The bumps of the electric vehicle will cause poor contact. For this reason, we have designed a headlight base structure for electric vehicles with good heat dissipation performance.
