Description

Technical Field

[0001] This utility model relates to the field of road sweeping robots, and in particular to a solar-powered intelligent road sweeping robot. Background Technology

[0002] With rapid urbanization, the workload of urban street cleaning has increased dramatically. Traditional cleaning methods mainly rely on manual labor and large cleaning vehicles. Manual cleaning is not only inefficient and extremely labor-intensive, but also highly susceptible to environmental factors such as weather and road conditions. For example, manual cleaning is virtually impossible during heavy rain or snow; and cleaning personnel face high safety risks in busy traffic areas. While large cleaning vehicles are highly efficient on wide main roads, their purchase and operating costs are extremely high, and they consume a lot of energy. More importantly, in areas with limited space, such as narrow streets and park paths, large cleaning vehicles have poor maneuverability and are difficult to operate effectively.

[0003] Currently, some small road cleaning robots have appeared on the market; however, most are battery-powered, resulting in severely limited battery life and requiring frequent charging, which greatly affects the continuity and efficiency of cleaning operations. At the same time, existing cleaning robots lack sufficient intelligence and struggle to cope with complex and changing road environments. For example, when encountering suddenly appearing obstacles, such as haphazardly parked vehicles or fallen branches, they cannot react promptly and accurately to avoid them, significantly reducing the cleaning effect.

[0004] In addition, clumps or filaments of debris, such as lint and hair, easily adhere to the bristles of the robot vacuum's main brush. This debris is not only difficult to remove, but it also reduces the cleaning performance of the main brush, requiring frequent cleaning by personnel.

[0005] Based on this, the present invention aims to create a solar-powered intelligent road sweeping robot, focusing on solving the problems of insufficient battery life, low level of intelligence and poor operational flexibility of existing road sweeping equipment, so as to achieve efficient, continuous and intelligent road sweeping operations. Utility Model Content

[0006] The purpose of this invention is to provide a solar-powered intelligent road sweeping robot that can operate outdoors for extended periods, has a large sweeping range, and high sweeping efficiency.

[0007] To achieve the above objectives, this utility model provides a solar-powered intelligent road sweeping robot, including a frame. The frame is equipped with a driving mechanism, a battery, a central processing unit, a wireless antenna, and a negative pressure garbage collection device. Side brushes are connected to the left and right sides of the front of the frame via side brush drive mechanisms, and a main brush is connected to the rear of the frame via a main brush drive mechanism. The negative pressure garbage collection device is located between the two side brushes and the main brush. A solar panel and a work indicator board are also provided on the top of the frame. The driving mechanism, battery, side brush drive mechanism, main brush drive mechanism, solar panel, work indicator board, and wireless antenna are all electrically connected to the central processing unit.

[0008] As a further improvement of this utility model, the main brush surface is provided with bristles, and the frame is provided with a bristle cleaning device; the bristle cleaning device includes a swing arm and blades, and a swing arm rotation drive device is connected between the swing arm and the frame; there are multiple blades connected to one end of the swing arm, and the multiple blades are arranged side by side to form a blade group, and the length of the blade group is adapted to the length of the main brush; when the blade swings with the swing arm, the blade passes between the horizontally adjacent bristles; the blade is located between the main brush and the garbage inlet end of the negative pressure garbage recycling device.

[0009] As a further improvement of this utility model, the swing arm rotation drive device includes a rotating shaft and a linear telescopic drive structure. The middle part of the swing arm is rotatably connected to the frame through the rotating shaft. One end of the linear telescopic drive structure is hinged to the end of the swing arm away from the blade, and the other end of the linear telescopic drive structure is hinged to the frame.

[0010] As a further improvement of this utility model, the negative pressure waste recycling device includes an inlet mask body, a pipe, a waste recycling bin and an exhaust fan connected in sequence along the airflow direction. The waste recycling bin is equipped with a dust collection bag, and the opening of the dust collection bag is connected to the output end of the pipe. The inlet mask body serves as the waste inlet end of the negative pressure waste recycling device.

[0011] As a further improvement of this utility model, the running mechanism of the frame includes omnidirectional wheels and drive wheels. The omnidirectional wheels are connected to the front of the frame, and there are two drive wheels located on both sides of the main brush. The drive wheels are connected to the frame through a drive wheel drive mechanism. The frame is provided with a main brush cavity, and the main brush is located in the main brush cavity.

[0012] As a further improvement of this utility model, the operation indicator board is arranged vertically, and a lidar is connected to its upper part. The lidar is higher than the solar panel, and the lidar is electrically connected to the central processing unit.

[0013] As a further improvement of this utility model, the solar-powered intelligent road sweeping robot also includes a vision sensor located at the front of the frame; multiple ultrasonic sensors are also provided on the outer periphery of the frame; a GPS sensor is also provided on the frame, and the vision sensor, GPS sensor and ultrasonic sensor are all electrically connected to the central processing unit.

[0014] Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model's solar-powered intelligent road sweeping robot are:

[0016] 1. Solar panels can charge the battery in a timely manner, giving the cleaning robot a longer runtime outdoors. This allows the robot to expand its cleaning area, reduce the number of times it needs to return to the charging station, and improve cleaning efficiency. The operation indicator board can remind pedestrians on the road to avoid the robot, reducing the risk of collisions.

[0017] 2. The brush cleaning device uses a rotating arm to move the blades of the blade assembly between adjacent horizontally aligned bristles. As the bristles rotate with the main brush, clumps or filaments attached to the bristles are blocked or cut by the blades, increasing the probability that these clumps or filaments will be sucked into the negative pressure waste collection device. This also ensures that the main brush's cleaning capacity remains within its normal range. When the blades are removed, the brush rotates more smoothly without obstruction.

[0018] 3. When the exhaust fan is blowing air, it creates negative pressure inside the waste recycling bin, drawing the waste swept up by the main brush into the dust collection bag through the inlet mask and pipes, thus improving waste recycling efficiency.

[0019] 4. LiDAR can perceive obstacles and environmental information around the robot in real time, helping the robot understand the layout of its environment. GPS sensors assist in detecting real-time position coordinates, providing the robot with more accurate close-range environmental information.

[0030] Example

[0031] The specific embodiments of this utility model are as follows: Figures 1 to 7 As shown, a solar-powered intelligent road sweeping robot includes a frame 1. The frame 1 is equipped with a driving mechanism, a battery 16, a central processing unit 17, a wireless antenna 10, and a negative pressure waste collection device 6. Side brushes 2 are connected to the left and right sides of the front of the frame 1 via side brush drive mechanisms 20, and a main brush 4 is connected to the rear of the frame 1 via a main brush drive mechanism 40. Both the side brush drive mechanisms 20 and the main brush drive mechanism 40 are motors. The negative pressure waste collection device 6 is located between the two side brushes 2 and the main brush 4. A solar panel 5 and a work indicator plate 8 are also provided on the top of the frame 1. The solar panel 5 is horizontally arranged, and the work indicator plate 8 is vertically arranged. The driving mechanism, battery 16, side brush drive mechanism 20, main brush drive mechanism 40, solar panel 5, work indicator plate 8, and wireless antenna 10 are all electrically connected to the central processing unit 17. As the cleaning robot moves forward, the two side brushes 2 on the left and right rotate around the vertical axis, sweeping the garbage in front of the cleaning robot into the area directly below the frame 1. The garbage is then swept up by the main brush 4 and finally sucked in and recycled by the negative pressure garbage recycling device 6.

[0032] The main brush 4 has bristles 41 on its surface, and a bristle cleaning device 7 is provided on the frame 1. The bristle cleaning device 7 includes a swing arm 72 and blades 71. A swing arm rotation drive device is connected between the swing arm 72 and the frame 1. There are multiple blades 71 connected to one end of the swing arm 72. The multiple blades 71 are arranged side by side to form a blade group, and the length of the blade group is adapted to the length of the main brush 4. When the blades 71 swing with the swing arm 72, the blades 71 pass between the horizontally adjacent bristles 41. The blades 71 are located between the main brush 4 and the waste inlet end of the negative pressure waste collection device 6.

[0033] The swing arm rotation drive device includes a rotating shaft 74 and a linear telescopic drive structure 73. The middle part of the swing arm 72 is rotatably connected to the frame 1 via the rotating shaft 74. One end of the linear telescopic drive structure 73 is hinged to the end of the swing arm 72 away from the blade 71, and the other end of the linear telescopic drive structure 73 is hinged to the frame 1. The linear telescopic drive structure 73 can be a hydraulic telescopic cylinder or a linear motor.

[0034] The negative pressure waste recycling device 6 includes an inlet mask 61, a pipe 62, a waste recycling bin 63, and an exhaust fan 64 connected sequentially along the airflow direction. The exhaust fan 64's outlet is connected to the outside. A dust collection bag 65 is installed inside the waste recycling bin 63, and the opening of the dust collection bag 65 is connected to the output end of the pipe 62. The dust collection bag 65 is made of a mesh structure, allowing air to pass through while blocking dust, thus recycling waste into the dust collection bag 65. The inlet mask 61 serves as the waste inlet of the negative pressure waste recycling device 6. When the exhaust fan 64 draws air, it creates a negative pressure inside the waste recycling bin 63, drawing the waste swept up by the bristles 41 of the main brush 4 into the dust collection bag 65 through the inlet mask 61 and the pipe 62.

[0035] In this embodiment, the cross-section of the inlet mask body 61 gradually narrows from the input end towards the pipe, guiding the incoming waste. The blade 71 is located on the outer side of the upper edge of the inlet mask body 61. Figure 5 As shown, the linear telescopic drive structure 73 extends at this time, while the blade 71 and the bristles 41 are staggered. Figure 6 As shown, when the linear telescopic drive structure 73 shortens and drives the swing arm 72 to rotate around the pivot 74 by a certain angle, the blade 71 relative to... Figure 5 When the blade 71 swings clockwise with its blade facing down, the bristles 41 of the main brush 4 rotate counterclockwise. At this time, if there are clumps or filaments attached between the adjacent bristles 41, they can be blocked or cut by the blade 71. The clumps and filaments are more easily sucked into the dust collection bag 65 by the mask body 61, and the surface of the bristles 41 is cleaner, ensuring its cleaning performance.

[0036] The driving mechanism of the frame 1 includes omnidirectional wheels 14 and drive wheels 3. The omnidirectional wheels 14 are connected to the front of the frame 1, and there are two drive wheels 3 located on either side of the main brush 4. The drive wheels 3 are connected to the frame 1 through drive wheel drive mechanisms 30. The frame 1 has a main brush cavity 11, and the main brush 4 is located inside the main brush cavity 11. In this embodiment, each drive wheel 3 is driven by a separate drive wheel drive mechanism 30, which is a motor. The cleaning robot moves forward or backward by rotating the two drive wheels 3 in the same direction. When the two drive wheels 3 rotate in opposite directions, the cleaning robot can turn.

[0037] The rotation direction of the main brush 4 is opposite to the rotation direction of the drive wheel 3 when the robot vacuum moves forward, such as in... Figure 3 In the middle, when the drive wheel 3 rotates clockwise, the cleaning robot moves forward to the right, at which time the main brush 4 needs to rotate counterclockwise.

[0038] The operation indicator board 8 is vertically arranged, with illuminated arrows pointing left and right on both its front and rear sides to warn pedestrians on the road and reduce the risk of collisions with the cleaning robot. A LiDAR 9 is connected to the upper part of the operation indicator board 8. The LiDAR 9 is higher than the solar panel 5 to avoid obstruction by the solar panel 5. The LiDAR 9 is electrically connected to the central processing unit 17. The LiDAR 9 perceives obstacles and environmental information around the robot in real time, constructing an accurate map.

[0039] The solar-powered intelligent road sweeping robot also includes a vision sensor 12, located at the front of the frame 1, specifically mounted on the front end of the solar panel 5. The vision sensor 12 identifies the type and distribution of litter on the road, providing a basis for developing a sweeping strategy. Multiple ultrasonic sensors 13 are also installed around the frame 1 to assist in detecting nearby obstacles and improve obstacle avoidance accuracy. A GPS sensor 15 is also installed on the frame 1 at its rear. The vision sensor 12, GPS sensor 15, and ultrasonic sensors 13 are all electrically connected to the central processing unit 17.

[0040] The GPS sensor 15, in conjunction with the wireless antenna 10, enables a stable communication connection between the robot and the remote control center. It can upload the robot's working status and location information in real time, while simultaneously receiving commands from the remote control center, achieving remote monitoring and control. This allows managers to easily monitor the robot's operation and intervene remotely.

[0041] This solar-powered intelligent road sweeping robot is compact in size and has a flexible locomotion mechanism, allowing it to easily adapt to different types of road environments, including narrow streets and park paths, effectively compensating for the blind spots of large sweeping vehicles. Using solar energy as its primary power source, it reduces energy consumption and pollutant emissions, aligning with current environmental protection principles and contributing to the construction of green cities.

[0042] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
