For the purpose of illustration, the drawings show only the structures associated with the embodiments of the application.

Referring to the drawings, in one embodiment of the present application, a sweeping robot 100 includes a sweeping robot body 10 and an anti-collision plate 20 installed on the sweeping robot body 10. In the embodiment of the present application, the sweeping robot 100 is a sweeping robot with a D-shaped overall shape, which is referred to as a D-shaped sweeping robot for short. Specifically, the impact prevention plate 20 is mounted to the front end of the sweeping robot body 10 in the traveling direction of the sweeping robot 100.

As shown in fig. 3, the bumper plate 20 is mounted to the sweeping robot body 10, and the bumper plate 20 includes a main body portion 21 and two side body portions 22, and the two side body portions 22 are respectively connected to two sides of the main body portion 21 along the first direction. Specifically, the main body portion 21 extends in a first direction, and the side body portion 22 extends in a second direction, and an angle between the first direction and the second direction is not less than 90 degrees. Preferably, the angle between the first direction and the second direction is greater than 90 degrees. Specifically, the first direction is the left-right direction shown in fig. 1. In the embodiment of the present application, the sweeping robot 100 further includes a collision switch, which is mounted on the sweeping robot body 10 and contacts with the bumper plate 20.

As shown in fig. 4 and 5, a mating member 30 is disposed on one side of each side body portion 22 facing the other side body portion 22, the sweeping robot body 10 is disposed with an elastic limiting member 40, the elastic limiting member 40 abuts against the corresponding mating member 20 along a first direction, and the elastic limiting member 40 is used for providing a tension force for enabling the two side body portions 22 to approach each other along the first direction. In some embodiments, multiple mating members 30 may be provided for each side body portion 22, but preferably, only one mating member 30 is provided for each side body portion 22.

Thus, when the integrally injection-molded anti-collision plate 20 is installed on the sweeping robot body 10, the elastic limiting piece 40 fixed on the sweeping robot body 10 is matched with the matching piece 30 on the anti-collision plate 20, the anti-collision plate 20 is limited by the elastic limiting piece 40, so that the two side body parts 22 which are deformed and expanded outwards can be drawn close to each other along the first direction to have a determined position relative to the sweeping robot body 10, and therefore, the relative position relationship between the anti-collision plate 20 and the collision switch installed on the sweeping robot body 10 can be determined to ensure that the collision switch is in an initial state, and the accuracy of triggering the collision switch by the anti-collision plate 20 is high.

In addition, it should be noted that, when the side body portion 22 on one side of the crash-proof plate 20 collides with a surrounding obstacle and moves backward, that is, moves toward the side body portion 22 on the other side, the force applied to the elastic limiting member 40 by the engaging member 30 of the side body portion 22 is reduced, the elastic deformation of the elastic limiting member 40 is reduced, and the side body portion 22 on the other side moves away from the side body portion 22 on the other side, so that the force applied to the elastic limiting member 40 by the engaging member 30 is increased, the elastic deformation of the elastic limiting member 40 is increased, the backward movement resistance of the side body portion 22 on the collided side is reduced, and further, the pressure applied to the corresponding crash switch by the side body portion 22 is sufficient, and the crash switch can be triggered in time, thereby improving the triggering sensitivity of the crash switch.

On the contrary, if the non-elastic limit structure is adapted to the fitting member 30, when the side body portion 22 on the collided side moves backward, the side body portion 22 on the other side is limited by the non-elastic limit structure, and the anti-collision plate 20 formed integrally has small elastic deformation, so that the backward movement resistance of the side body portion 22 on the collided side is large, the backward movement amount of the side body portion 22 on the collided side is insufficient, the pressure acting on the collision switch is insufficient, the collision switch cannot be triggered sensitively, and the sensing of obstacles on two sides of the whole machine is affected.

In short, the sweeping robot 100 of the present application not only can make the two deformed and flared side body portions 22 draw close to each other along the first direction to have a certain position relative to the sweeping robot body 10, so that the accuracy of triggering the collision switch by the anti-collision plate 20 is high, but also the triggering sensitivity of the collision switch can be improved.

Referring to fig. 2 again, in the embodiment of the present application, the sweeping robot body 10 includes a housing 11, specifically, the housing 10 includes an upper housing component, a lower housing and a bottom cover, and the elastic limiting member 40 is fixed to the upper housing component.

In some embodiments, the elastic limiting members 40 are disposed on a side surface of the sweeping robot body 10 along a fourth direction, wherein the first direction, the fourth direction and the traveling direction of the sweeping robot 100 are perpendicular to each other. Specifically, the fourth direction is a vertical direction. Preferably, the elastic limiting member 40 is disposed on the upper surface of the sweeping robot body 10 along the vertical direction, so that a space is provided for the elastic deformation of the elastic limiting member 40, and the fitting member 30 on the impact-proof plate 20 is adapted to the corresponding elastic limiting member 40, so that the assembly process is simpler.

In some embodiments, the bumper plate 20 has a protrusion 23 disposed along the edge circumference and protruding toward the sweeping robot body 10, the sweeping robot body 10 has an inwardly recessed recess 111, the protrusion 23 can be received in the recess 111, the elastic limiting member 40 is disposed in the recess 111, and the engaging member 30 is disposed in the protrusion 23. Specifically, the concave portion 111 is provided on the cabinet 11. When the elastic limiting member 40 is disposed in the concave portion 111 and the engaging member 30 is disposed in the convex portion 23, a deformation space for elastically deforming the elastic limiting member 40 in the first direction is provided. Specifically, the concave portion 111 is provided on the upper surface of the sweeping robot body 10 in the vertical direction.

Referring to fig. 4 again, further, the elastic limiting member 40 includes a cantilever 41, the cantilever 41 extends along a second direction intersecting the first direction, the cantilever 41 includes a fixed end and a suspension end, the fixed end is fixed to the sweeping robot body 10, and the elastic limiting member 40 abuts against the mating member 30 at the suspension end.

Specifically, the second direction is the up-down direction shown in fig. 1.

Furthermore, the sweeping robot body 10 is provided with a first limiting portion 12 and a second limiting portion 13 which are oppositely arranged along the first direction, and the cantilever 41 is limited between the first limiting portion 12 and the second limiting portion 13 along the first direction. By providing the first stopper portion 12 and the second stopper portion 13, the cantilever 41 is protected from the deformation limit while the cantilever 41 has a sufficient deformation space in the first direction, and the cantilever 41 is prevented from being excessively deformed to be broken and damaged.

Specifically, in an embodiment, the sweeping robot body 10 is provided with a limiting groove 14, the cantilever 41 is located in the limiting groove 14, and two inner walls of the limiting groove 14, which are oppositely arranged along the first direction, are used as the first limiting portion 12 and the second limiting portion 13.

In some embodiments, the elastic limiting member 40 further includes a first abutting portion 42, the first abutting portion 42 is disposed at the suspension end, the first abutting portion 42 extends along a third direction, and the elastic limiting member 40 abuts against the mating member 30 through the first abutting portion 42, wherein the first direction, the second direction and the third direction intersect each other. Specifically, the third direction is a vertical direction. The provision of the first abutting portion 42 extending in the third direction makes it possible to increase the abutting area against the attachment 40, so that the two side body portions 22 deformed to be flared can be reliably drawn toward each other in the first direction.

Further, the thickness of the first abutment portion 42 in the first direction is larger than the thickness of the cantilever 41 in the first direction. Specifically, the first abutment portion 42 and the cantilever 41 may be combined in an L-shape. Thus, the structural strength of the first abutting portion 42 can be enhanced to improve the reliability of the first abutting portion 42 abutting against the mating member 30.

Referring to fig. 5 again, in some embodiments, the mating element 30 includes a second abutting portion 31, the second abutting portion 31 extends along the third direction, and the elastic limiting member 40 abuts against the mating element 30 through the first abutting portion 42 and the second abutting portion 31. The first abutting part 41 and the second abutting part 32 which extend in the third direction are arranged to abut against each other, so that the position interference between the sweeping robot body 10 and the anti-collision plate 20 in a plane parallel to the first direction can be reduced as much as possible, and the collision sensing of the anti-collision plate 20 is improved.

Further, the bumper plate 20 has a side wall 24 along the circumferential direction, the fitting 30 further includes a reinforcement portion 32, the second abutting portion 31 is disposed at an interval from the side wall 24 along the first direction, the reinforcement portion 32 extends along the first direction, and both ends of the reinforcement portion along the first direction are respectively connected to the second abutting portion 31 and the side wall 24.

Specifically, in one embodiment, the second abutting portion 31 extends along the second direction, and further, the reinforcing portion 32 may include a plurality of reinforcing portions 32, and the plurality of reinforcing portions 32 are disposed at intervals along the second direction. Thus, the structural strength of the fitting member 30 can be enhanced to be stably fitted with the elastic limiting member 40.

Furthermore, the side of the second abutting portion 31 away from the reinforcing portion 32 is connected to the sidewall 24, and the sidewall, the second abutting portion 31 and the reinforcing portion 32 are surrounded to form an annular structure.

In other embodiments, the elastic limiting member 40 is integrally formed with the housing 11 of the sweeping robot body 10, and the engaging member 30 is integrally formed with the side body portion 22.
