Wherein, rubber strip 10 and crashproof main part 20 laminating are fixed through waterproof high temperature resistant transparent silica gel glue. The anti-collision main body 20 is formed by welding a bending steel pipe and two matched and assembled parts on two sides, and a pin shaft penetrates through a hole site of the matched and assembled parts on two sides of the anti-collision main body 20 and a middle hole of the torsion spring 60 to be assembled at the middle position of the anti-collision bracket 50. Wherein, the torsion spring 60 is at the innermost side, the anti-collision main body 20 is matched with the assembly part to be positioned in the middle, and the anti-collision bracket 50 is at the outermost side. The torsion spring 60 adopts a right-handed structure, one side of the extension parts at two ends is contacted with the anti-collision bracket 50, the other side is contacted with the anti-collision main body 20, the pin shaft penetrates through the hole site obliquely below the anti-collision bracket 50 to play a supporting role, the anti-collision main body 20 is kept at a horizontal position, meanwhile, the torsion spring 60 starts to bear force, and the extension two sides start to rotate and shrink due to the fact that the anti-collision main body 20 rotates around the pin shaft. Preferably, the bearing bracket 40 and the anti-collision bracket 50 are fixed together on the small mower body by using bolts through the U-shaped holes of the bearing bracket 40 and two thread clearance holes at the rear side of the anti-collision bracket 50. Preferably, the safety contact edge 30 and the rubber block 70 are fixed on the bearing brackets 40 on two sides through bolts.
In this embodiment, when the whole set of anti-collision structure is acted, the first layer of rubber strip 10 is impacted by force, so that the anti-collision main body 20 starts to rotate around the pin shaft, preferably, the rubber strip 10 plays a role in first layer buffering, and meanwhile, soft rubber contacts with foreign objects, so that the contact surface is not damaged easily. The anti-collision main body 20 rotates to drive one side of the torsion spring 60 to start to be stressed and extruded to rotate, and as the other side of the torsion spring 60 is fixed on the anti-collision bracket 50, the torsion spring 60 starts to play a second layer of buffering function. When the anti-collision main body 20 contacts the surface of the safe contact edge 30, and meanwhile, the other side of the anti-collision main body is in contact with the rubber block 70, the rubber block 70 plays a third layer of buffering function, and the situation that the anti-collision main body 20 is not easy to cause the safe contact edge 30 to be damaged under the action of external force is guaranteed, and the safe contact edge 30 transmits signals to enable the small mower to brake and stop running when power is off.
Specifically, in this example, there is a certain adjustment range for the U-shaped hole below the bearing bracket 40, and the distance between the safety contact edge 30 and the collision avoidance main body 20 is adjusted by adjusting the position where the U-shaped hole is fixed with the bolt. When the distance is close, the anti-collision main body 20 is in contact with the safety contact edge 30 in the moment of being stressed, so that the small mower can be rapidly stopped. In this case, the time for which the impact body 20 contacts the safety margin 30 to generate the induction after receiving the impact rotation becomes controllably adjustable.
