The working principle of the protective frame for the unmanned sweeping vehicle provided by the utility model is as follows:

when the vehicle body 1 works on a road surface, the warning lamp 47 breathes and flashes to remind passers-by to pay attention to avoidance, and the adjusting frame 22 below the chassis 21 adjusts the position (horizontal position and height) and the angle of the cleaning disc 23, so that the cleaning disc 23 can better cover the garbage position, and the cleaning efficiency is improved; meanwhile, in the working state, the top surface of the side display screen 38 is positioned between the chassis 21 and the vehicle body 1, the anti-collision frame 39 on the top surface of the side display screen 38 protects the periphery of the vehicle body 1, when collision occurs, the anti-collision frame 39 bears the collision, the support 39a provides stable support, meanwhile, the side display screen 38 moves towards the interior between the vehicle body 1 and the chassis 21 due to the impact force, the side display screen 38 drives the buffer rod 37 to slide towards the buffer cylinder 35, the buffer rod 37 presses the buffer spring 36, the impact force from the outside is counteracted by the reaction force of the buffer spring 36, so that the buffer effect is achieved, and the damage to the vehicle body 1 is reduced. When the car body 1 breaks down and stops on the road surface and can't move, the warning light 47 twinkles fast, people and vehicles in time dodge around the car body 1 broadcast voice prompt, simultaneously, all around the car body 1 bottom surface hydraulic pump 31 starts, makes telescopic link 32 extension, telescopic link 32 passes through connecting seat 34 promotes the buffer tube 35 slides, buffer tube 35 passes through buffer rod 37 drives side display 38 follow car body 1 with between the chassis 21 slides out, side display 38 drives bump frame 39 removes, works as telescopic link 32 stretches to the biggest time, side display 38 slides out completely car body 1 with outside the chassis 21, subsequently accommodate motor 33 rotates, drives the rotation seat rotates ninety degrees, the rotation seat passes through buffer tube 35 with buffer rod 37 drives side display 38 rotates ten degrees (side display 38 front outwards perpendicular with the bottom surface), finally car body 1 all erects from between car body 1 and the chassis 21, side display 38 rolls simultaneously, and the side display 38 is bright: "machine failure, attention avoidance-! "waiting for warning words; in this process, the rotating motor 41 at the top of the vehicle body 1 is started, the rotating gear 45 inside the housing 42 is driven to rotate by the transmission gear 43, the rotating gear 45 drives the supporting rod 44 to rotate, and the supporting rod 44 drives the top display screen 46 to rise, so that the top display screen 46 is vertically erected at the top of the vehicle body 1, and the two sides of the top display screen 46 also display the warning sign in a rolling manner, and the top display screen 46 at a high position is higher than most vehicles, so that the warning sign is more easily observed by drivers at a distance in the vehicles, can prevent and avoid in advance, and greatly avoids accidents; after the fault is relieved, the side display screen 38 and the top display screen 46 are closed, the warning lamp 47 stops flashing, the rotating motor 41 is reversed, the rotating gear 45 is driven to rotate reversely in the shell 42 through the transmission gear 43, the rotating gear 45 drives the top display screen 46 to rotate to an initial position through the supporting rod 44, and the top display structure 4 is retracted; meanwhile, the adjusting motor 33 reverses to drive the rotating seat to reverse, the rotating seat drives the side display screen 38 to reversely rotate through the buffer cylinder 35 and the buffer rod 37, so that the side display screen 38 returns to a horizontal state, then the hydraulic pump 31 drives the telescopic rod 32 to retract, the hydraulic rod drives the buffer cylinder 35 and the buffer rod 37 to move towards the inside of the vehicle body 1 and the chassis 21 through the rotating seat, the buffer rod 37 drives the side display screen 38 to enter the inside of the vehicle body 1 and the chassis 21, and meanwhile, the side display screen 38 drives the anti-collision frame 39 to return to an initial position, and the side display structure 3 is retracted. The device has the advantage of being capable of obviously and timely giving out avoidance warning to surrounding pedestrians and vehicles.

the utility model provides a protection frame for an unmanned sweeper, wherein when the side display structure 3 is retracted between the sweeper body 1 and the chassis 21, the protection frame can be realized through the anti-collision frame 39, and the impact force of external impact is counteracted by the reaction force generated by compressing the buffer spring 36 when the buffer rod 37 slides in the buffer cylinder 35, so that the damage to the sweeper body 1 is reduced; when the side display structure 3 and the top display structure 4 are unfolded, surrounding pedestrians can timely find and avoid through highlighting rolling display warning words around and at the top of the vehicle body 1, and a driver in the vehicle at a distance can observe by utilizing the advantage of the height of the top display screen 46, so that accidents can be prevented and avoided in advance to a great extent. The warning device has the advantage of being capable of obviously and timely giving out avoidance warning to surrounding pedestrians and vehicles.
