[0002] With the development and growth of urbanization, there is more and more garbage. Cleaning only by sanitation workers is time-consuming, laborious and inefficient. Therefore, some cities have equipped with automatic environmental sanitation robots to clean the city, reducing the burden on sanitation workers and improving the cleaning efficiency.

[0003] For example, the patent with the publication number CN210554636U discloses an anti-collision buffer structure for an automatic environmental sanitation robot. The top of the base is fitted with a device main body. The four corners of the bottom end of the base are provided with rollers. The sides of the base are arranged with brackets at equal intervals. An anti-collision device is movably installed on the brackets. The anti-collision device includes a triangular frame and shock-absorbing wheels. The shock-absorbing wheels are movably fitted at the three vertices of the triangular frame, and a bearing is arranged between the triangular frame and the shock-absorbing wheels. A silicone gear sleeve is sleeved on the side of the shock-absorbing wheel. In this application, a circle of anti-collision devices is arranged outside the base of the environmental sanitation robot. During the operation of the environmental sanitation robot, if it accidentally touches an obstacle or the roadside, the shock-absorbing wheels on the anti-collision device roll, so that the horizontal impact force of the environmental sanitation robot is converted into a force with a side arc, thus changing the hard impact force into an elastic frictional force to reduce the impact on the main body of the environmental sanitation robot.

[0004] However, in the prior art, an anti-collision mechanism is usually required to protect the environmental sanitation robot during operation to extend the service life of the device. However, the anti-collision mechanism will wear out after long-term use and needs to be replaced and repaired regularly. At present, the existing anti-collision mechanisms of environmental sanitation robots are usually integrally installed, which is inconvenient to replace the anti-collision mechanism, thus limiting the practicality of the device to a certain extent. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the prior art, the existing anti-collision mechanisms of environmental sanitation robots are usually integrally installed, which is inconvenient to replace the anti-collision mechanism and the practicality is limited.

[0006] To achieve the above object, the utility model adopts the following technical solution: an anti-collision buffer structure for a sanitation robot, including a main body, wherein a plurality of detachable components are arranged at equal intervals in a circular shape on the outer surface of the main body. The detachable component includes a connecting block. An installation groove is formed at the center position of the upper surface of each connecting block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: an anti-collision buffer structure for a sanitation robot, including a main body 1. A number of detachable components are arranged at equal intervals in a circular shape on the outer surface of the main body 1. The detachable component includes a connecting block 2. An installation groove 3 is opened at the center position of the upper surface of each connecting block 2. Limiting grooves 4 are symmetrically opened at both ends of the upper surface of each connecting block 2 close to the installation groove 3. A first guiding rod 5 is fixedly connected to the inner side wall of each limiting groove 4. A moving block 7 is slidably connected to the surface of each first guiding rod 5. One side of each moving block 7 is fixedly connected to the inner side wall of the limiting groove 4 through a return spring 6. A limiting block 8 is fixedly connected to the upper surface of each moving block 7. The outer side walls of the two limiting blocks 8 are fixedly connected with a handle 9. When the anti-collision mechanism is worn and needs to be regularly inspected and replaced, only need to pull the handle 9 to both sides. The handle 9 guides and slides through the moving block 7 in the first guiding rod 5. When the moving block 7 slides in the first guiding rod 5, the return spring 6 will be stretched. At this time, the anti-collision mechanism to be replaced is clamped and placed in the installation groove 3. At this time, the return spring 6 quickly resets and drives the limiting block 8 to limit the anti-collision mechanism. The disassembly and assembly are convenient, improving the practicability of the device.

[0023] As Figures 1-4 shown, an anti-collision mechanism is arranged in the inner cavity of the installation groove 3. The anti-collision mechanism includes an installation block 10 clamped in the installation groove 3. A first guiding groove 11 is opened in the inner cavity of the installation block 10. A second guiding rod 12 is slidably connected to the inner cavity of the first guiding groove 11. One end of the second guiding rod 12 is fixedly connected with a fixed block 13. The inner side of the fixed block 13 is fixedly connected to the outer side wall of the installation block 10 through a first buffer spring 14. A number of buffer plates 15 arranged at equal intervals are embedded on the side of the fixed block 13 away from the first buffer spring 14. When the collision force is too large, at this time, when the buffer plates 15 are impacted, they will compress the first buffer spring 14 through the fixed block 13 and make the second guiding rod 12 move in the first guiding groove 11, thereby providing secondary protection for the device and extending the service life of the device.

[0024] As Figures 1-4As shown in the figure, connecting rods 16 are fixedly connected to both the upper and lower surfaces of the fixed block 13. A rotating block 17 is rotatably connected to one end of each connecting rod 16 away from the fixed block 13. A number of second guiding grooves 18 are annularly formed on the surface of each rotating block 17. Second buffer springs 19 are fixedly connected to the inner side walls of the number of second guiding grooves 18. One end of each second buffer spring 19 is fixedly connected to a movable rod 20. A connecting seat 21 is fixedly connected to one end of the movable rod 20. A bumper 22 is movably connected to the outer side wall of each connecting seat 21. And the movable rod 20 is slidably connected to the second guiding groove 18. When a collision occurs, the bumper 22 will be collided first. The bumper 22 slides in the second guiding groove 18 through the connecting seat 21 and the movable rod 20 and compresses the second buffer spring 19 for effective buffering and shock absorption. And the rotating block 17 rotates in the connecting rod 16, so that the stress point of the collision force can be adjusted, thereby protecting the device, and further extending the service life of the device.

[0025] Working principle: When in use, first, the mounting block 10 is snap-fitted and placed in the mounting groove 3. While the mounting block 10 moves downward, it will squeeze the limiting blocks 8 on both sides. The limiting blocks 8 guide and slide through the moving blocks 7 in the first guiding rods 5 and compress the return springs 6. When the mounting block 10 fits with the mounting groove 3, at this time, the limiting blocks 8 no longer receive lateral acting forces, and the return springs 6 quickly rebound to drive the moving blocks 7 to slide and reset in the first guiding rods 5, so that the limiting blocks 8 move to the upper surface of the mounting block 10 for limiting. The disassembly and assembly are convenient, improving the practicability of the device. When the device collides, the bumper 22 will be collided first. The bumper 22 slides in the second guiding groove 18 through the connecting seat 21 and the movable rod 20 and compresses the second buffer spring 19 for effective buffering and shock absorption. And the rotating block 17 rotates in the connecting rod 16, so that the stress point of the collision force can be adjusted. When the collision force is too large, at this time, when the buffer plate 15 is impacted, it will compress the first buffer spring 14 through the fixed block 13 and make the second guiding rod 12 move in the first guiding groove 11, thereby providing secondary protection for the device and further extending the service life of the device. The overall structure of the device is simple and the operation is convenient, which is suitable for large-scale popularization.

[0026] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
