The height of the anti-collision fences 6 is less than the height of the sweeper body 1, and the length of the anti-collision fences 6 is greater than the length between the two tires on one side of the bottom of the sweeper body 1. Slide rails 10 are symmetrically arranged on the inner side of each anti-collision fence 6, and the slide rails 10 are fixed on the side wall of the sweeper body 1, and a slide rod 12 is fixed inside each slide rail 10, and each moving block 9 and a spring 11 are slidably sleeved on the slide rod 12, and a slide groove matching the moving block 9 is provided inside the slide rail 10, and a moving block 9 is symmetrically slidably sleeved inside each slide rail 10, and one end of the moving block 9 extending to the outside of the slide rail 10 is rotatably connected to the connecting rod 8, and the other end of each connecting rod 8 is rotatably connected to the anti-collision fence 6, and a spring 11 is fixed between each group of two moving blocks 9 and between the moving block 9 and the inner wall of the slide rail 10.
[0027] Specifically, when the anti-collision fence 6 is hit, the impact force drives the connecting rod 8 to rotate, and the connecting rod 8 pushes the moving block 9 when it rotates. When the moving block 9 moves, the spring 11 is stretched and compressed, and the spring 11 can be used for buffering protection, thereby converting the lateral impact force into a vertical squeezing force, preventing the sweeper body 1 from tipping over, and providing buffering protection at the same time.
[0028] As an optimization solution, Figure 3 and Figure 5As shown, the bottom of the sweeper body 1 is fixed with an anti-collision chassis 13 by bolts, and the bottom surface of the sweeper body 1 diagonally opposite to the anti-collision chassis 13 is provided with an electric push rod 21, and the output end of the electric push rod 21 is rotatably connected to a suction cup 22, and the bottom surfaces of the two suction cups 22 are flush with the bottom surface of the anti-collision chassis 13, a gyroscope is provided inside the sweeper body 1, and the anti-collision chassis 13 is symmetrically slidably sleeved with a moving plate 14, and a support plate 18 is fixed on the inside of the anti-collision chassis 13 inside each moving plate 14, and a moving rod 19 is slidably inserted inside the support plate 18, and a spring three 20 is sleeved on the moving rod 19 outside the support plate 18, and the two ends of the spring three 20 are respectively fixed on the support plate 18 and the moving rod 19, and the two moving plates 1 4, one end extending to the outside of the anti-collision chassis 13 is fixed on the inner wall of the anti-collision fence 6, a conversion slider 15 is symmetrically slidably arranged inside the anti-collision chassis 13 between the two moving plates 14, and the two sides of the conversion slider 15 are slidably fitted with the side edges of the moving plates 14, the middle part of each conversion slider 15 is slidably sleeved on the slide bar 17, and the two ends of the slide bar 17 are fixed on the inner wall of the anti-collision chassis 13, and the two springs 16 in the middle are slidably sleeved on the slide bar 17, the two moving plates 14 and the conversion slider 15 are arranged in a "cross" shape, and the two sides of each conversion slider 15 are arranged to be inclined outwardly in coordination with the two sides of the moving plate 14, and a plurality of springs 16 are equidistantly fixed between the outer side of each conversion slider 15 and the inside of the anti-collision chassis 13.
[0029] Specifically, when the anti-collision fence 6 moves, it also pushes the moving plate 14, so that the moving plate 14 moves to squeeze the conversion slider 15, which can make the conversion slider 15 move to both sides to squeeze the spring 2 16, and the restoring force of the spring 2 16 can offset part of the squeezing force, further perform buffering protection, disperse and transfer the direction of the impact force, and when the moving plate 14 moves, it drives the moving rod 19 to move the compression support plate 18, and also performs buffering protection for the anti-collision fence 6.
