Description

Technical Field

[0001] The utility model provides an anti-collision buffer device for a floor sweeping robot, belonging to the technical field of floor sweeping robots. Background Art

[0002] As an important product in the field of smart home, the floor sweeping robot has been widely used rapidly since its advent. Its main function is to automatically clean the floor, reduce manual labor, and improve the convenience of home cleaning. Modern floor sweeping robots not only have basic functions of dust collection and cleaning, but also gradually integrate technologies such as intelligent control and environmental perception, becoming a key component in the smart home system.

[0003] Existing floor sweeping robots can already use sensors to avoid the robot hitting obstacles and prevent the floor sweeping robot from hitting obstacles during operation. However, the setting of such an anti-collision system is often aimed at static objects. When a fast-moving dynamic object in the outside world directly hits the floor sweeping robot, the anti-collision buffer effect of the floor sweeping robot is poor at this time.

[0004] In response to the above problems, existing solutions often avoid the impact of high-speed external objects by setting buffer structures around the floor sweeping robot; for example, a floor sweeping robot anti-collision buffer structure disclosed in the patent publication number CN220158184U can protect against the impact of external objects by setting four protective plates with anti-collision buffer devices. However, to achieve the impact buffer effect, the four protective plates cannot be completely closed, and there are gaps between the protective plates, resulting in a poor protection effect. When the volume of the impact object is small and just aligns with the gap between the protective plates, the floor sweeping robot cannot be effectively protected. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that there are gaps between the protective plates of the existing floor sweeping robot, which affects the protection effect.

[0006] To solve the above problems, the technical solution proposed by the present utility model is: an anti-collision buffer device for a floor sweeping robot, including a buffer structure, and the buffer structure is arranged outside the main body of the floor sweeping robot; a moving wheel body and a dust suction port are arranged below the main body of the floor sweeping robot, and an infrared sensor is arranged on the floor sweeping robot; a route control system is arranged inside the main body of the floor sweeping robot, and the infrared sensor is electrically connected to the route control system; the buffer structure includes an outer buffer plate and an inner buffer plate, both the outer buffer plate and the inner buffer plate are arranged outside the main body of the floor sweeping robot, and both the outer buffer plate and the inner buffer plate are connected to the main body of the floor sweeping robot through elastic buffer components; the outer buffer plate is located outside the inner buffer plate, there is a gap between the outer buffer plate and the inner buffer plate, and the projections of the outer buffer plate and the inner buffer plate facing the side wall of the floor sweeping robot can cover the entire side wall of the floor sweeping robot; an emergency transformation module electrically connected to the route control system is arranged above the infrared sensor.

[0007] As an improvement, there are two outer buffer plates and two inner buffer plates; in the same clockwise or counterclockwise direction, the inner buffer plate and the outer buffer plate are arranged adjacent to each other.

[0008] As an improvement, the elastic buffer component includes a sliding column and a buffer spring; sliding columns are horizontally and fixedly connected to the inner walls of the outer buffer plate and the inner buffer plate, a sliding groove is formed in the main body of the floor sweeping robot, and the sliding columns are slidably inserted into the sliding groove; the buffer spring is located outside the main body of the floor sweeping robot, and the buffer spring is sleeved on the sliding column.

[0009] As an improvement, a limiting block is slidably arranged in the sliding groove, and the limiting block is fixedly arranged at the end of the sliding column.

[0010] As an improvement, a data analysis module is arranged in the emergency transformation module, and the data analysis module is electrically connected to the infrared sensor.

[0011] The beneficial effects of the present utility model are:

[0012] 1. Both the outer buffer plate and the inner buffer plate are connected to the main body of the floor sweeping robot through elastic buffer components, which can play a buffering role when being impacted by high-speed objects from the outside, reducing the possibility of the floor sweeping robot being damaged by impact. The outer buffer plate is located outside the inner buffer plate, and the projections of the outer buffer plate and the inner buffer plate facing the side wall of the floor sweeping robot can cover the entire side wall of the floor sweeping robot; by setting two groups of buffer plates with internal and external dislocation, it not only ensures the movement buffering of the buffer plates under normal impact conditions, but also can ensure the protection effect on the floor sweeping robot.

[0013] 2. An emergency transformation module connected to the circuit of the route control system is provided above the infrared sensor; when a high-speed object in the outside world hits the main body of the sweeping robot, the emergency transformation module can control the route control system to urgently change the walking route, so that the sweeping robot can move a certain distance along the direction of the impact, thereby improving the buffering effect.

[0020] The present utility model will be further described below with reference to the accompanying drawings.

[0021] According to Figures 1-5 As shown: The present utility model provides an anti-collision and buffering device for a sweeping robot: including a buffering structure, and the buffering structure is arranged outside the main body 1 of the sweeping robot; a moving wheel body 9 and a dust suction port 10 are arranged below the main body 1 of the sweeping robot, and an infrared sensor 7 is arranged on the sweeping robot; a route control system is arranged inside the main body 1 of the sweeping robot, and the infrared sensor 7 is electrically connected to the route control system; the buffering structure includes an outer buffer plate 2 and an inner buffer plate 3, both the outer buffer plate 2 and the inner buffer plate 3 are arranged outside the main body 1 of the sweeping robot, and both the outer buffer plate 2 and the inner buffer plate 3 are connected to the main body 1 of the sweeping robot through an elastic buffering component; the outer buffer plate 2 is located outside the inner buffer plate 3, there is a gap 8 between the outer buffer plate 2 and the inner buffer plate 3, and the projections of the outer buffer plate 2 and the inner buffer plate 3 facing the side wall of the sweeping robot can cover the entire side wall of the sweeping robot; an emergency transformation module 6 connected to the circuit of the route control system is provided above the infrared sensor 7.

[0022] By setting two groups of buffer plates with internal and external dislocation, the mobility of the buffer plates is ensured, and the protection range of the floor sweeping robot is increased, thereby enhancing the protection effect. Moreover, an emergency transformation module 6 is set, which can urgently change the route of the floor sweeping robot when a collision occurs, thus increasing the buffer protection effect.

[0023] As Figures 1-3 shown, there are two outer buffer plates 2 and two inner buffer plates 3. In the same clockwise or counterclockwise direction, the inner buffer plate 3 and the outer buffer plate 2 are arranged adjacent to each other, so as to ensure the dislocation of adjacent buffer plates.

[0024] As Figure 4 shown, the elastic buffer assembly includes a sliding column 5 and a buffer spring 4. Both the outer buffer plate 2 and the inner wall of the inner buffer plate 3 are horizontally fixedly connected with a sliding column 5. A sliding groove 12 is opened in the floor sweeping robot main body 1, and the sliding column 5 is slidably inserted into the sliding groove 12. The buffer spring 4 is located outside the floor sweeping robot main body 1, and the buffer spring 4 is sleeved on the sliding column 5, which can play a buffering role when a collision occurs. A limiting block 11 is slidably arranged in the sliding groove 12, and the limiting block 11 is fixedly arranged at the end of the sliding column 5 to prevent the outer buffer plate 2 and the inner buffer plate 3 from detaching from the floor sweeping robot main body 1.

[0025] As Figure 5 shown, the emergency transformation module 6 is provided with a data analysis module, and the data analysis module is electrically connected to the infrared sensor 7, which can collect and analyze the data of the infrared sensor 7 and the changes in the data, so as to facilitate changing the walking route of the floor sweeping robot by using the emergency transformation module 6 when a collision occurs.

[0026] The principle of the present utility model

[0027] As Figure 1 、 2 shown is the normal working state diagram of the anti-collision buffer device of the floor sweeping robot of the present application. The infrared sensor 7 can monitor the surrounding environment and transmit the data to the route control system to prevent the floor sweeping robot from touching other objects during walking.

[0028] At the same time, the projections of the outer buffer plate 2 and the inner buffer plate 3 on the side wall of the floor sweeping robot can cover the entire side wall of the floor sweeping robot, so that the side wall of the floor sweeping robot can be completely protected. At the same time, the outer buffer plate 2 and the inner buffer plate 3 are arranged with internal and external dislocation and there is a gap 8, which will not affect the mobility of the outer buffer plate 2 and the inner buffer plate 3 when receiving impact buffering. As Figure 4 、 5As shown in the figure, when an external high-speed object collides, first, the infrared sensor 7 can sense the rapid changes of the object about to collide. The data analysis module in the emergency transformation module 6 can collect and analyze the data sensed by the infrared sensor 7. For the route of the object to collide, the route control system is quickly adjusted through the emergency transformation module 6 to change the moving route of the sweeping robot, so that the sweeping robot moves along the moving direction of the colliding object, thereby reducing the impact and shock. At the same time, when the object collides with the outer buffer plate 2 or the inner buffer plate 3, the outer buffer plate 2 or the inner buffer plate 3 pushes the sliding column 5 to slide in the sliding groove 12. At the same time, the outer buffer plate 2 or the inner buffer plate 3 compresses the buffer spring 4, and the buffer spring 4 can buffer the impact.

[0029] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.
