DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A taillight for an electric vehicle, such as Figures 1 to 5 As shown, it includes a lampshade 1 and a lamp housing 2, the outer wall of the lamp housing 2 is provided with a groove, the inside of the groove is filled with hot melt adhesive 10, the edge of the lampshade 1 is inserted into the inside of the groove and fixedly connected to the lamp housing 2, a reflector 6 is installed inside the lamp housing 2, a screw 12 is fixed on the outside of the reflector 6, the reflector 6 is fixedly connected to the lamp housing 2 through the screw 12, there are two groups of screws 12, the two groups of screws 12 are respectively located at the top and bottom of the reflector 6, a first circuit board 8 is located on the outside of the top screw 12, a second circuit board 9 is installed at the center of the reflector 6, an inner cover 4 is installed at the bottom end of the reflector 6, the reflector 6 is snap-connected with the lampshade 1 through the inner cover 4, an outer decorative ring 3 is installed on the outside of the lampshade 1, and a plurality of groups of fixed hanging ears 201 are installed on the outer wall of the lamp housing 2, and each group of fixed hanging ears 201 is fixed to the outer wall of the lamp housing 2. The ears 201 are all provided with screw holes 202 inside, bolts and sealing caps 5 are installed inside the screw holes 202, an extrusion column 501 is installed inside the sealing cap 5, the sealing cap 5 is fitted with the bolt through the extrusion column 501, a thread 502 is installed on the outside of the extrusion column 501, the sealing cap 5 is snap-fitted with the screw hole 202 through the thread 502, a sealing ring 503 is connected to the outside of the sealing cap 5, the sealing ring 503 is sleeved on the outside of the screw hole 202, a protruding ridge 203 is provided on the outside of the screw hole 202, the sealing ring 503 is inserted into the inside of the protruding ridge 203, thereby sealing the screw hole 202, a breathing cap 11 is installed on the back of the lamp housing 2, so that the air inside the lamp can be exchanged with the outside when the lamp is used, to avoid excessive pressure changes inside the lamp.

[0033] See also Figure 3 A decorative piece 7 is installed inside the lampshade 1 , and the decorative piece 7 is aligned with the reflector 6 .

[0034] See also Figure 6 , which is the second embodiment of the present application. The difference is that the structures of the fixed hanging ear 201 and the sealing cap 5 are different. The specific difference is that the length of the sealing ring 503 is greater than the protruding length of the screw hole 202. When the sealing cap 5 is fixed to the screw hole 202, the outer side of the sealing ring 503 is bent and squeezed on the outer wall of the screw hole 202, and fits tightly with the outer wall of the screw hole 202, thereby reducing the structural complexity of the fixed hanging ear 201 and facilitating production. In addition, the longer sealing ring 503 fits with the outer wall of the fixed hanging ear 201, which can also achieve a sealing effect.

[0035] When fixing the lampshade 1, inject hot melt adhesive 10 into the groove on the outside of the lamp shell 2, then fix the lampshade 1 to the outside of the lamp shell 2, and insert the edge of the lampshade 1 into the groove of the lamp shell 2 to fix the lampshade 1. After the hot melt adhesive 10 cools down, the lampshade 1 and the lamp shell 2 are fixed. Then, install the lamp on the electric vehicle, align the screw hole 202 with the fixing hole on the electric vehicle frame, and fix the lamp by passing the bolt through the screw hole 202. After fixing, fix the sealing cap 5 on the outside of the screw hole 202 and rotate the sealing cap 5 until the sealing cap 5 fits tightly against the outside of the bolt, thereby sealing the bolt, reducing the contact between the bolt and the outside, thereby reducing the oxidation of the bolt and increasing the service life of the bolt.
