The utility model discloses an anti-collision mechanism which comprises an anti-collision unit and a protection unit, the anti-collision unit comprises an anti-collision support, an anti-collision plate and a reset assembly, the anti-collision support is movably connected with the anti-collision plate, the reset assembly is arranged on the anti-collision support, and the protection unit comprises a laser sensor and a microswitch. The laser sensor is arranged on the first L-shaped piece, the microswitch is arranged on the second L-shaped piece, and laser of the laser sensor penetrates through the partition space M. The top sorting component has the advantages that the top sorting component firstly makes contact with the inclined head-on collision plate when adsorbing foreign matter in the operation process, the height of the elastic piece is larger than that of the limiting rod, and therefore the top sorting component can be separated from the inclined head-on collision plate. The elastic piece resists impact of foreign matter so as to protect the linear motor, the fixing plate can limit the rotation angle of the baffle, and the elastic piece resets the anti-collision plate.

The invention relates to a method (100) for actuating an occupant restraint device of a vehicle (1) on the basis of a signal of an environment sensing component of the vehicle (1) in the event that the vehicle (1) is or is about to collide with a collision object (2), the occupant restraint device comprising a forward restraint means and a lateral restraint means, the method (100) comprises the following steps in a pre-collision phase in which an unavoidable collision occurs in the vehicle (1):-detecting (101) the collision as an oblique collision by means of environmental sensor data acquired from signals of environmental sensor components,-ascertaining (102) in each case a forward collision component and a lateral collision component from the environmental sensor data, -actuating (103) the forward restraint means as a function of the forward impact component and / or actuating the lateral restraint means as a function of the lateral impact component. The invention also relates to a device for actuating an occupant restraint device of a vehicle (1) in the event of a collision of the vehicle (1) with a collision object (2) occurring or imminent, comprising an electronic control unit designed to carry out the method (100) according to any of the preceding claims.

The invention relates to an anti-collision buffer structure, a side brush device and cleaning equipment. A floating disc of the anti-collision buffer structure is arranged below a fixed disc and is not in direct rigid connection with the fixed disc; the touch electronic switch is annular and sleeves the periphery of the floating disc; the elastic pieces are distributed in the circumferential direction of the fixed disc at equal intervals, and the floating disc elastically abuts against the lower surface of the fixed disc through the elastic pieces. The floating disc elastically abuts against the fixed disc, and therefore the floating disc can deflect relative to the fixed disc in the oblique collision process, and the collision coping capacity of the floating disc is all-directional. When the floating disc is collided from any direction, collision force causes deformation of the elastic piece at the corresponding position, the floating disc generates displacement to absorb impact energy, and meanwhile the touch electronic switch detects collision and outputs a collision signal. And after the collision force is relieved, symmetrical elastic force generated by the elastic pieces distributed at equal intervals in the circumferential direction jointly acts to drive the floating disc to reset to the initial state of being centered with the fixed disc, so that rigid collision damage is avoided, and the structural stability is kept.
