Description

Technical Field

[0001] The invention relates to the technical field of opening and closing the front fender of a three-wheeled or four-wheeled sweeper, and in particular to an automatic opening and closing structure of the front fender of a sweeper. Background Art

[0002] Today, sweepers and sanitation vehicles are widely used by sanitation companies, cleaning services, property management companies, and businesses. During cleaning operations, sweepers are required to remove large trash such as beverage bottles, cans, and leaves into trash receptacles. Traditional sweepers use a foot- or hand-operated mechanism to open and close the front flap. As the industry evolves, demands for lightweight operation and the ability to quickly flip and reset the front flap electrically are becoming increasingly important. However, existing sweepers with automatic front flap opening and closing mechanisms struggle to properly clean large trash such as beverage bottles and cans, resulting in reduced efficiency.

[0003] The existing automatic opening and closing structure of the front guard of the sweeper has the following defects:

[0004] 1. Patent document CN118177673A discloses a quick-disassembly and quick-assembly barrier structure for cleaning and maintenance equipment, which includes a barrier frame, a barrier mounting frame, and a fixed arc plate. The barrier mounting frame is symmetrically mounted on the outer end of the barrier frame, the height adjustment seat is movably mounted on the inner side of the barrier mounting frame, the sliding block is mounted on the outer end of the height adjustment seat, and the docking outer protrusion is movably mounted on the inner side of the extrusion groove. The present invention is provided with a lifting adjustment component on the inner side of the barrier mounting frame, and the height adjustment seat drives the sliding block to move up and down the barrier mounting frame. The inner side is slid to adjust the height of the guard frame, and the sweeping roller brush slot is engaged with the sweeping roller brush. After installation, the docking outer protrusion pops out and engages with the inner side of the docking limit hole to achieve the limit fixation of the use position of the height adjustment seat. The height of the guard frame can be quickly adjusted according to the use requirements of the sweeper, thereby improving the cleaning efficiency while ensuring the cleaning area and cleaning quality. However, the existing sweeper with an automatic opening and closing structure of the front guard cannot clean normally when encountering large-volume garbage such as beverage bottles and cans, and the working efficiency is reduced;

[0005] 2. Patent document CN108937738A discloses a sweeper that prevents garbage leakage. "It includes a sweeper body and a carriage, the carriage being located at one end of the sweeper body, a side brush rod being fixedly mounted on the bottom of the carriage, a side brush being threadedly connected to the bottom of the side brush rod, the side brush rod being located inside the carriage, and the side brush being located outside the carriage, and a roller being fixedly mounted on the other end of the sweeper body, the roller being connected to the side brush rod via a belt. This sweeper that prevents garbage leakage is provided with a garbage shovel and a baffle, so that the sweeper can scoop up garbage and pour it into an internal garbage basket formed by a first receiving plate and side walls, and the garbage is not easily dropped out of the garbage basket, thereby effectively enhancing the cleaning function of the sweeper. By providing an opening and closing door, garbage is prevented from easily leaking out after entering the garbage bin from the suction port, further enhancing the cleaning effect of the sweeper." However, the automatic opening and closing structure of the front baffle of existing sweepers cannot automatically control the reset motor to drive the front baffle to open, reducing work efficiency.

[0006] 3. Patent document CN108209742A discloses an indoor automatic sweeper, "including a cleaning chamber, a front nozzle, side baffles, a trash bin, universal wheels, a trash bin cover, a chassis, a handle, a vent, a push rack, a front nozzle, a side nozzle, a rear nozzle, a garbage inlet, an electric motor, etc. The cleaning chamber is arranged at the front side of the trash bin, a front nozzle is arranged at the bottom of the front end of the cleaning chamber, a push rack is arranged at the rear of the trash bin, the chassis is arranged above the cleaning chamber, and an air pressure pump is arranged on one side of the motor. This product achieves efficient and rapid cleaning of garbage, and can not only clean large volumes of garbage, but also clean dust or fruit peels and paper scraps. Compared with existing indoor sweeper products, this product cleans more cleanly, more quickly and efficiently, is smaller in size, and can clean garbage in a small area." However, the camera of the automatic opening and closing structure of the front baffle of the existing sweeper cannot automatically clean, reducing detection accuracy;

[0007] 4. Patent document CN113309030B discloses a hand-pushed conveyor belt brush automatic sweeper with a control handle. "It includes a garbage collection mechanism, a power transmission mechanism, a garbage cleaning mechanism, and a frame. The garbage collection mechanism includes a garbage basket, a garbage basket buckle, and a garbage basket roller; the power transmission mechanism includes a belt, a small pulley, a large pulley, a rear wheel, and a front wheel; the garbage cleaning mechanism includes a sweeping brush, a sweeping brush roller, a garbage shovel, and a garbage shovel control mechanism; the frame includes a guard, a handle, a shovel frame, a garbage bag fixing card, a garbage retaining frame, and a buckle core. The present invention converts human thrust into the sweeper's cleaning power and adopts manual control of whether to sweep. The garbage shovel is provided with a crawler shovel as a crawler structure. When the garbage shovel moves downward, the crawler shovel connected to it adapts to uneven road surfaces through gravity, the rolling of the rollers, and its own structural characteristics. This saves the cost of electrical equipment and effectively improves the garbage cleaning ability." However, the front guard of the existing sweeper with an automatic opening and closing structure cannot be quickly adjusted in length, which reduces collection efficiency. Summary of the Invention
