[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] A rear taillight housing of an electric vehicle with an anti-fog function comprises a taillight frame 1, a taillight housing 2, a defogger brush 3, a gear box 5 and a support arm 7. The taillight housing 2 is installed on the outside of the taillight frame 1, and a gear box 5 is provided on the side of the taillight housing 2. A rotating arm 10 is installed on the outside of the gear box 5 through a swing shaft, and a rotating rod 9 is movably installed on the top of the rotating arm 10 through a bearing. One end of the rotating rod 9 is connected to a side plate 4, and a defogger brush 3 is installed on the inner side of the side plate 4. A circuit board 16 is provided on the inner surface of the taillight frame 1, and a plurality of LED lamp beads 17 are provided on the surface of the circuit board 16. The circuit board 16 and the LED lamp beads 17 of this application are both existing disclosed structures, and the wiring can be the same as that of the existing disclosed taillight body.

[0020] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a rear taillight housing of an electric vehicle with an anti-fog function. Specifically, a driving gear 11 and a driven gear 12 are movably provided inside the gear box 5, and the driving gear 11 and the driven gear 12 are meshed and connected. The center of the driven gear 12 is sleeved on the swing shaft. A motor is provided inside the taillight housing 2, which can drive the driving gear 11 to rotate. The driving gear 11 is meshed with the driven gear 12 to drive the driven gear 12 to rotate, and the rotating arm 10 and the driven gear 12 are fixed on the same axis. Therefore, the rotating arm 10 can rotate and swing, driving the defogger brush 3 to swing. The defogger brush 3 defogs and removes debris from the outer wall of the taillight housing 2. The defogger brush 3 of this application is a cotton brush cylinder.

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a rear taillight housing of an electric vehicle with an anti-fog function. Specifically, a locking bolt is provided at one end of the swing shaft, and one end of the locking bolt passes through the rotating arm 10 and is threadedly engaged with the locking nut on the outside of the rotating arm 10. When the rotating arm 10 is installed, it is fixed by the locking bolt and the locking nut thread.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the utility model is a rear taillight housing of an electric vehicle with an anti-fog function. Specifically, a support arm 7 is provided at the side position of the taillight frame 1, a slide groove is opened inside the support arm 7, and cover plates 8 are provided on both sides of the slide groove. The cover plates 8 cover the outside of the slide groove to prevent external water vapor from entering the inside of the slide groove and affecting the spring 15 inside the slide groove.

[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a rear taillight housing of an electric vehicle with an anti-fog function. Specifically, a guide rod 13 is provided inside the slide groove, and a slide seat 14 is provided on the outer movable sleeve of the guide rod 13, and the bottom end of the slide seat 14 is fixedly connected to the outer wall of the taillight housing 2. A spring 15 is provided at one end of the guide rod 13, and the spring 15 is an existing disclosed structural component. The guide rod 13 and the slide seat 14 are both metal parts.

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a rear taillight lamp housing of an electric vehicle with an anti-fog function. Specifically, a dust cover 6 is provided at the bottom end of the taillight housing 2, and a dustproof rubber sleeve 18 is provided between the taillight frame 1 and the taillight housing 2. The dustproof rubber sleeve 18 of the present application is made of natural resin material, and mainly serves to connect the taillight frame 1 and the taillight housing 2 to prevent water from entering the connection between the taillight frame 1 and the taillight housing 2. Since the taillight housing 2 is movable, and the dustproof rubber sleeve 18 is elastic, it will not affect the movement of the taillight housing 2.

[0025] When the taillight housing 2 is hit, the taillight housing 2 pushes the slide 14 to slide toward one side of the spring 15. The spring 15 contracts and deforms under pressure to provide a buffering capacity, thereby removing the impact force brought by the taillight housing 2, thereby preventing the lamp body inside the taillight housing 1 from being protected. At the same time, the present invention also provides a swingable defogging brush 3 on the outside of the taillight housing 2, which can drive the rotating arm 10 to rotate through the cooperation of the driving gear 11 and the driven gear 12, thereby driving the defogging brush 3 installed at one end of the rotating arm 10 to slide on the outer wall of the taillight housing 2. The defogging brush 3 can remove water vapor and impurities on the outer wall of the taillight housing 2. In this way, when the taillight is illuminated, there is no water vapor on the outside, and the lighting is clearer.
