[0028] Please refer to Figure 1-7, the present utility model discloses a front headlight for an electric tricycle, including a lamp housing 1, the lamp housing 1 is detachably connected with a lamp cover 2, a circuit board 5 is installed in the lamp housing 1, a reflector 3 is installed in the inner cavity of the lamp housing 1 above the circuit board 5, an LED lamp 4 electrically connected to the circuit board 5 and extending into the inner cavity of the reflector 3 is installed in the inner cavity of the lamp housing 1, and a heat dissipation plate 6 is arranged at the rear side of the lamp housing 1.

[0029] The lamp housing 1 can be made of aluminum alloy material to improve the heat dissipation performance of the lamp housing 1.

[0030] The heat dissipation plate 6 penetrates through the lamp housing 1 and contacts the back side of the circuit board 5, and a thermal conductive silicone pad can be arranged between the heat dissipation plate 6 and the circuit board 5.

[0031] Specifically, a fixed edge 7 with a flange is connected to the outer wall of the lamp housing 1, a positioning groove 8 is formed between the fixed edge 7, the flange of the fixed edge 7 and the outer wall of the lamp housing 1, and a positioning edge 9 that can be inserted into the positioning groove 8 is fixedly connected to the bottom end of the lamp cover 2.

[0032] Both outer walls of the fixed edge 7 are fixedly connected with a limiting block 11 that is integrally U-shaped, the opening of the limiting block 11 is in the direction away from the lamp cover 2, one end of the limiting block 11 close to the lamp cover 2 extends upward and is higher than the flange of the fixed edge 7, a part of the inner cavity of the limiting block 11 is higher than the flange and forms a clamping groove 12, both outer walls of the positioning edge 9 are fixedly connected with clamping blocks 13, and the clamping blocks 13 can be clamped into the clamping groove 12.

[0033] A PE sealing strip 10 is arranged in the positioning groove 8.

[0034] In this implementation scheme, the whole positioning edge 9 can be inserted into the positioning groove 8, and the clamping blocks 13 are made of PC material or other elastic plastic materials.

[0035] During the process of inserting the positioning edge into the positioning groove 8, the end of the clamping block 13 can contact the side of the limiting block 11 close to the inner cavity of the lamp housing 1 and undergo elastic deformation, because one end of the limiting block 11 close to the lamp cover 2 extends upward and is higher than the flange of the fixed edge, and the opening of the limiting block 11 is in the direction away from the lamp cover 2, so there is a part of the inner cavity of the limiting block 11 above the flange, and the part of the inner cavity of the limiting block 11 above the flange and the flange cooperate to form the clamping groove 12. When the positioning edge 9 is completely inserted into the positioning groove 8, the clamping block 13 is located at the clamping groove 12, and at this time, the clamping block 13 is restored and can be clamped into the clamping groove 12.

[0036] The setting of the PE sealing strip 10 can play a role in sealing and waterproofing after the lamp housing 1 and the lamp cover 2 are connected.

[0037] Specifically, both outer walls of the fixed edge 7 are fixedly connected with mounting blocks, and mounting holes are formed in the mounting blocks.

[0038] In this embodiment, the lamp housing 1 can be installed on the corresponding installation position of the electric tricycle through the cooperation of the mounting holes on the mounting block 14 and bolts.

[0039] Specifically, the lamp cover 2 is made of PC material.

[0040] In this embodiment, the lamp cover 2 made of PC material can resist high temperature and prevent aging.

[0041] In summary, for the headlamp of the electric tricycle, the lamp cover 2 and the lamp housing 1 are convenient to disassemble and install, which is convenient for maintenance and replacement of the damaged components inside the lamp housing 1. By setting the heat dissipation plate 6 on the lamp housing 1, it is possible to avoid the way of opening air vents for the exchange of hot air and external air, and it can prevent dust or water vapor from entering the lamp housing 1.
