[0002] In the context of the rapid development of intelligent technology and automation technology, the application fields of driverless vehicle technology have been continuously expanding. From logistics distribution, agricultural cultivation to urban transportation, the presence of driverless vehicles is becoming more and more common. In this trend, a driverless vehicle for park road cleaning with positioning technology has become a new and forward-looking application direction. This kind of driverless vehicle combines advanced positioning systems, environmental perception technologies, autonomous navigation algorithms and efficient cleaning equipment, aiming to provide efficient, environmentally friendly and intelligent road cleaning solutions for various parks, such as commercial parks, industrial parks, university campuses, parks and residential areas, etc. The positioning technology plays a crucial role in the driverless cleaning vehicle. It not only ensures that the driverless vehicle can accurately drive on the preset route and avoid obstacles, but also enables it to achieve autonomous navigation in complex environments and complete the cleaning tasks. Usually, the driverless cleaning vehicle will adopt the integration of multiple positioning technologies, such as the Global Positioning System (GPS), Inertial Navigation System (INS) and Visual Positioning System (VPS), etc., to improve the positioning accuracy and reliability. In addition, the driverless cleaning vehicle is also equipped with an advanced environmental perception system, including cameras, ultrasonic sensors and lidar, etc., for real-time monitoring of the surrounding environment, identifying obstacles and pedestrians to ensure safe driving. The autonomous navigation algorithm is based on these perception data, combined with the positioning information, to plan the optimal cleaning route and dynamically adjust the traveling direction and speed to adapt to different cleaning requirements and environmental changes.

[0003] Most of the existing driverless vehicles for park road cleaning with positioning technology fix the brushes with bolts. When disassembling, cleaning or replacing the brushes, tools are needed for disassembly and installation, which is time-consuming and laborious. And in case of emergency, replacing the brushes may not be completed quickly. At the same time, under different environments and cleaning requirements, different types and sizes of brushes are required. If it is inconvenient to replace the brushes, it will limit the cleaning adaptability and flexibility of the driverless vehicle. Summary of the Utility Model

[0033] By setting the cooperation of structures such as the pushing block 105 and the fixing block 204, it is convenient for the staff to load, unload and replace the brush 207. During installation, only need to align the clamping block 202 with the clamping groove 103, move the mounting seat 201 in the direction close to the turntable 102, so that the bottom of the turntable 102 presses the inclined surface of the fixing block 204. Through the inclined surface, the fixing block 204 moves into the clamping block 202 and presses the second spring 203 until the clamping block 202 is clamped with the turntable 102. At this time, the fixing block 204 is clamped with the fixing groove 104 under the action of the elastic force of the second spring 203 to complete the fixation. When it is necessary to disassemble, clean or replace the brush 207, only need to push the push rod 106 in the direction close to the turntable 102, so that the pushing block 105 moves in the direction close to the fixing block 204, squeeze the fixing block 204 into the clamping block 202, and then pull out the mounting seat 201 downward.

[0034] Embodiment 2

[0035] Reference Figures 1 to 3, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The cleaning mechanism 200 includes a mounting base 201. A clamping block 202 is fixedly connected to the top of the mounting base 201. A second spring 203 is provided in the inner wall of the clamping block 202. Both ends of the second spring 203 are fixedly connected to a fixed block 204. An inclined surface is provided at the top of the fixed block 204. The two fixed blocks 204 respectively penetrate through the inner wall of the clamping block 202 and extend to both sides of the clamping block 202. The two fixed blocks 204 are elastically connected by the second spring 203. The size of the fixed block 204 is adapted to the size of the fixed slot 104. The fixed block 204 is clamped with the fixed slot 104. One end of the fixed block 204 away from the second spring 203 abuts against the push block 105. The size of the clamping block 202 is adapted to the size of the clamping slot 103. The clamping block 202 is clamped with the clamping slot 103.

Both the turntable 102 and the mounting base 201 are rotatably connected to the rotating groove 304.

[0038] By setting the cooperation of structures such as the piston rod 206 and the third spring 205, the brush 207 can adapt to and clean the undulating road surface. When the brush 207 sweeps over the undulating road surface, the magnitude of the reaction force exerted by the road surface on the brush 207 is different. Thus, the amplitude of the piston rod 206 pressing upward on the gas inside the sealing groove 208 and the third spring 205 is also different. Therefore, the height of the brush 207 can be adaptively adjusted according to the magnitude of the pressure, so that the brush 207 can clean the undulating road surface.
