[0002] A sweeping robot is a smart home appliance that can be used to clean the floor. It can automatically complete floor cleaning tasks in the room, bringing great convenience to people's daily lives and becoming a commonly used household appliance in office workers' homes.

[0003] When using a sweeping robot, as it is an artificial intelligence product, its perception of objects and directions is achieved through its own positioning system and detection system. As a result, the sweeping robot often collides with furniture, walls, etc. when cleaning. Over time, it is easy to damage not only the sweeping robot but also the furniture. To this end, we have designed an anti-collision buffer structure for the sweeping robot to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A collision-proof buffer mechanism for a sweeping robot comprises a sweeping robot body, a side array of which is provided with a plurality of buffer plates, the buffer plates being of an arc-shaped structure, and a buffer mechanism being further provided between the inner arc surface of the buffer plate and the sweeping robot body, the buffer mechanism comprising a fixed block, a hollow cylinder, a telescopic column, a first spring and a connecting rod, a side of the sweeping robot being provided with an interlayer, the fixed block being fixedly installed in the interlayer, and a hollow cylinder being fixedly provided in the fixed block, telescopic columns being symmetrically and movably inserted at both ends of the hollow cylinder, and first springs being symmetrically installed at the ends of the two telescopic columns in the hollow cylinder, the telescopic columns being connected to the inner arc surface of the buffer plate through a connecting rod, wherein the two ends of the connecting rod are hinged to the telescopic column and the buffer plate respectively.

[0007] As a further solution of the present invention: a plurality of grooves are symmetrically formed on the outer arc surface of the buffer plate, and rollers are rotatably installed in the grooves.

[0008] As a further solution of the present invention: a rubber sleeve is installed on the outer surface of the roller.

[0009] As a further solution of the present invention: a ball seat is also installed in the fixed block, a universal ball adapted thereto is installed in the ball seat, a sleeve is fixedly installed on the universal ball, an insertion rod is movably inserted in the sleeve through a second spring, and the insertion rod is fixedly connected to the inner arc surface of the buffer plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model provides a buffer plate, a fixed block, a hollow cylinder, a telescopic column, a first spring and a connecting rod. When a collision occurs on the side of the sweeping robot body, the buffer plate can flip accordingly according to the direction of the collision. The flipped buffer plate can drive the telescopic column to be inserted into the hollow cylinder under the action of the connecting rod. Cooperating with the first spring provided in the hollow cylinder, it can buffer the collision and thus protect the sweeping robot body. In addition, the combination of the buffer plate and the buffer mechanism can also enable the sweeping robot to cope with collisions in different directions, and has the advantage of good anti-collision performance.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods. Example

[0022] See also Figure 1-6 , a sweeping robot anti-collision buffer mechanism, including a sweeping robot body 1, a side array of the sweeping robot body 1 is provided with a plurality of buffer plates 2, the buffer plates 2 are arc-shaped, and a buffer mechanism is also provided between the inner arc surface of the buffer plate 2 and the sweeping robot body 1, the buffer mechanism includes a fixed block 4, a hollow cylinder 5, a telescopic column 6, a first spring 7 and a connecting rod 8, the side of the sweeping robot is provided with an interlayer 3, the fixed block 4 is fixedly installed in the interlayer 3, and a hollow cylinder 5 is fixedly provided in the fixed block 4, the two ends of the hollow cylinder 5 are symmetrically inserted with telescopic columns 6, and the ends of the two telescopic columns 6 in the hollow cylinder 5 are also symmetrically installed with first springs 7, the telescopic columns 6 are connected to the buffer by the connecting rod 8 The inner arc surface of the punching plate 2 is connected, wherein the two ends of the connecting rod 8 are hinged to the telescopic column 6 and the buffer plate 2 respectively. By setting the buffer plate 2, the fixed block 4, the hollow tube 5, the telescopic column 6, the first spring 7 and the connecting rod 8, when a collision occurs on the side of the sweeping robot body 1, the buffer plate 2 can be flipped accordingly according to the direction of the collision. The flipped buffer plate 2 can drive the telescopic column 6 to be inserted into the hollow tube 5 under the action of the connecting rod 8, and cooperate with the first spring 7 set in the hollow tube 5 to buffer the collision, thereby protecting the sweeping robot body 1. In addition, the combination of the buffer plate 2 and the buffer mechanism can also enable the sweeping robot to cope with collisions in different directions, and has the advantage of good anti-collision performance.

[0023] Among them, the outer arc surface of the buffer plate 2 is also symmetrically provided with a plurality of grooves 9, and a roller 10 is rotatably installed in the groove 9. The setting of the roller 10 can reduce the friction between the buffer plate 2 and the wall or furniture when the buffer plate 2 hits the wall or furniture, which is conducive to changing the direction of the sweeping robot body 1.

[0024] In addition, a rubber sleeve 11 is installed on the outer surface of the roller 10. The provision of the rubber sleeve 11 avoids rigid collision between the roller 10 and the wall or furniture, and plays a further buffering role in the event of collision. Example

[0025] This embodiment is improved on the basis of embodiment 1, specifically:

[0026] See also Figure 3 and Figure 4, a ball seat 12 is also installed in the fixed block 4, and a universal ball 13 adapted thereto is installed in the ball seat 12, and a sleeve 14 is fixedly installed on the universal ball 13, and a rod 15 is movably inserted in the sleeve 14 through a second spring 16, and the rod 15 is fixedly connected to the inner arc surface of the buffer plate 2. Specifically, the rod 15 is located at the center position of the inner arc surface of the buffer plate 2. The arrangement of the ball seat 12, universal ball 13, sleeve 14, rod 15 and second spring 16, when the sweeping robot hits a wall or furniture, the second spring 16 can further buffer the impact, and the universal ball 13 and the ball seat 12 can also adapt to impacts on the buffer plate 2 in different directions, further improving the anti-collision effect of the sweeping robot.

[0027] Working principle: When the sweeping robot collides with a wall or furniture, the roller 10 on the buffer plate 2 contacts the wall or furniture first, and the rubber sleeve 11 on the roller 10 can play a primary buffering role for the impact. When the buffer plate 2 flips over during the collision, the flipped buffer plate 2 can drive the telescopic column 6 to be inserted into the hollow tube 5 under the action of the connecting rod 8, and cooperate with the first spring 7 set in the hollow tube 5 to play a secondary buffering role for the impact. In addition, during the process of the buffer plate 2 being hit, the second spring 16 can play a tertiary buffering role for the impact, and the universal ball 13 and the ball seat 12 can also adapt to the impact of the buffer plate 2 in different directions, further improving the anti-collision effect of the sweeping robot.
