[0019] An embodiment of the present application discloses an anti-collision mechanism for a brush disc of an electric sanitation vehicle. Refer to Figures 1-4 , an anti-collision mechanism for a brush disc of an electric sanitation vehicle, including a chassis 1, a fixed frame 5 fixedly connected to the inner wall of the middle section of the chassis 1, and two connecting plates 6 fixedly connected to the outer wall of the bottom of the fixed frame 5 through a buffer mechanism. Two connecting pieces 7 are fixedly connected to the outer wall of the bottom of the two connecting plates 6. Hydraulic rods 8 are hinged to the inner walls of the two connecting pieces 7. The output ends of the two hydraulic rods 8 are fixedly connected together to form a brush disc frame 9. Two brush discs 10 are installed on the outer wall of the bottom of the brush disc frame 9. A U-shaped member 11 is fixedly connected to the outer wall of the middle section of the top of the brush disc frame 9. A buffer spring 12 is installed in the inner cavity of the U-shaped member 11. The buffer mechanism includes a plurality of limit frames 17 fixedly connected to the outer walls of the tops of the two connecting plates 6. Two sliders 18 are slidably connected to the inner walls of the plurality of limit frames 17. Connecting rods 19 are hinged to the outer walls of the two sliders 18 outside the limit frames 17. The ends of the plurality of connecting rods 19 away from the sliders 18 are hinged to the outer wall of the bottom of the fixed frame 5. Damping springs 20 are fixedly connected to the outer walls of every two opposite sliders 18.

[0020] A top plate 16 is fixedly connected to the outer wall of the middle section of the fixed frame 5. A fixed frame 15 is fixedly connected to the outer wall of the bottom of the top plate 16. A connecting block 14 is rotatably connected to the inner wall of the bottom end of the fixed frame 15.

[0021] A movable rod 13 is movably connected to the inner wall of the U-shaped member 11. The top end of the movable rod 13 penetrates through the U-shaped member 11. The end of the connecting block 14 away from the fixed frame 15 is hinged to the top end of the movable rod 13.

[0022] One end of the buffer spring 12 is fixedly connected to the outer wall of the bottom of the movable rod 13, and the other end of the buffer spring 12 is fixedly connected to the outer wall of the top of the brush disc frame 9.

[0023] A fixed plate 2 is fixedly connected to the outer wall of the bottom of one end of the chassis 1. A front wheel 3 is installed on the outer wall of the bottom of the fixed plate 2. Two rear wheels 4 are installed on the outer wall of the bottom of the end of the chassis 1 away from the front wheel 3.

[0024] The implementation principle of an anti-collision mechanism for the brush disc of an electric sanitation vehicle in an embodiment of the present application is as follows: During use, the hydraulic rod 8 is used to drive the lifting of the brush disc frame 9. When the brush disc frame 9 descends and the brush disc 10 hits a ground protrusion, since the movable rod 13 is movably connected to the inner wall of the U-shaped member 11, and the movable rod 13 is fixed to the bottom end of the fixed frame 15 through the connecting block 14. When the brush disc frame 9 drives the U-shaped member 11 to move upward, the movable rod 13 is cooperatively pressed against the buffer spring 12. The elastic force generated by the deformation of the buffer spring 12 initially buffers the brush disc frame 9. At the same time, the brush disc frame 9 and the brush disc 10 will upwardly press the connecting plate 6, causing the connecting plate 6 to press the buffer mechanism. Multiple connecting rods 19 in the buffer mechanism rotate relatively obliquely, driving the two sliders 18 to slide relatively and press the damping spring 20. The elastic force generated by the deformation of the damping spring 20 acts in the opposite direction on the connecting plate 6 to buffer the upward movement amplitude of the connecting plate 6, further buffering the brush disc frame 9 and the brush disc 10 when hitting the protrusion, avoiding hard contact with the protrusion due to the fixation of the brush disc 10, thereby damaging the equipment, playing a role in buffering and anti-collision. At the same time, when the chassis 1 drives the two brush discs 10 to move through the front wheels 3 and the rear wheels 4, it will often come into contact with the uneven ground. At this time, the brush disc frame 9, through the buffer spring 12 and multiple damping springs 20 in the buffer mechanism, enables the brush disc frame 9 to have an elastic buffering effect, so that the brush disc frame 9 and the brush disc 10 can always elastically contact the uneven ground. Compared with the fixedly installed brush disc frame 9 and brush disc 10 in the prior art, it can avoid the direct hard contact between the brush disc frame 9 and the brush disc 10 with the ground, can adapt to different usage environments, reduce the damage caused during collisions, and has a good anti-collision effect.
