Description

[Technical field]

[0001] The utility model relates to an LED car lamp, in particular to an installation structure of a fan of the LED car lamp. [Background technology]

[0002] LED car lights use LED light-emitting diodes as light sources. During use, LEDs will generate a lot of heat, so fans need to be installed to dissipate the heat.

[0003] When installing LED headlights currently on the market, the fan circuit board is fixedly installed with the driver circuit board of the LED headlight and the circuit is connected. The installation method adopts a pin welding process, that is, the pins are welded at the lower end of the fan circuit board, and then the pins are inserted into the corresponding holes of the driver circuit board of the LED headlight and welded again to fix it. At the same time, the fan circuit board and the driver circuit board are connected through the solder joints.

[0004] However, this method has great defects: 1. In the actual production / installation of the fan, the fan circuit board must be welded and installed in advance, and then the pins must be inserted into the corresponding holes of the driver circuit board for welding. The welding position is small, and the pins are prone to loosening during the welding process. The welding process requires high requirements, and there are serious risks of welding leakage and cold welding, and the production efficiency is low; 2. When the finished LED lamps are produced, because the fan pins are small, when inserting them into the corresponding holes on the LED lamp driver circuit board, it is difficult to identify and insert, which is time-consuming and laborious; and after the pins are welded, the excessively long pins need to be manually cut off. The manually cut pins are uneven, the quality risks are great, and the work efficiency is extremely low. At the same time, the positive and negative polarity directions of the fan poles are easy to be inserted in reverse, the welding is easy to be skewed, and cold welding occurs, resulting in the loosening of the fan. Due to the vibration caused by the rotation of the fan and the bumps of the vehicle, the solder joints are broken, resulting in short circuits and safety hazards. At the same time, the labor cost is seriously wasted, causing serious quality risks and cost waste for the manufacturers of LED lamps. [Summary of the invention]

[0005] The utility model provides an LED car lamp, comprising an LED car lamp body, in which a fan is installed, and the fan is fixedly connected with a driving circuit board in the LED car lamp body through a connecting bracket and the whole circuit is connected.

[0008] Circuit elements are arranged on both outer sides of the connecting bracket, and corresponding recessed card slots are arranged on both inner sides, and the lowermost end of the connecting bracket is an insertion position.

[0009] The fixing buckles on both sides of the fan circuit board are inserted into the recessed slots of the connecting bracket, and the connection parts are welded to form limit lock pin welding points, so that the fan circuit board and the connecting bracket are fixedly connected and the circuit is connected.

[0010] The insertion position at the lower end of the connecting bracket is inserted into the installation position of the driving circuit board, and the connection is welded and fixed to form a limit lock pin welding point.
