Figure 2 Shows Figure 1 The exploded structural schematic diagram of the floor cleaning robot shown. Figure 3 Shows Figure 1 The structural schematic diagram of the anti-collision plate in the floor cleaning robot shown. For ease of description, the drawings only show the structures related to the embodiments of this application.

[0044] Referring to the accompanying drawings, an embodiment of the present application provides a floor sweeping robot 100, which includes a floor sweeping robot body 10 and a collision avoidance plate 20 installed on the floor sweeping robot body 10. In the embodiment of the present application, the floor sweeping robot 100 is a floor sweeping robot with an overall D-shaped configuration, hereinafter referred to as a D-shaped floor sweeping robot. Specifically, the collision avoidance plate 20 is installed at the front end of the floor sweeping robot body 10 along the traveling direction of the floor sweeping robot 100.

[0045] As Figure 3 shown, the collision avoidance plate 20 is installed on the floor sweeping robot body 10. The collision avoidance plate 20 includes a main body portion 21 and two side body portions 22. The two side body portions 22 are respectively connected to both sides of the main body portion 21 along a first direction. Specifically, the main body portion 21 extends along the first direction, and the side body portion 22 extends along a second direction. The 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 Figure 1 the left-right direction shown. In the embodiment of the present application, the floor sweeping robot 100 further includes a collision switch, which is installed on the floor sweeping robot body 10 and is in contact with the collision avoidance plate 20.

[0046] As Figure 4 and Figure 5 shown, a fitting 30 is provided on one side of each side body portion 22 facing the other side body portion 22. The floor sweeping robot body 10 is provided with an elastic limiting member 40. The elastic limiting member 40 abuts against the corresponding fitting 30 along the first direction. The elastic limiting member 40 is used to provide a tensile force that causes the two side body portions 22 to approach each other along the first direction. In some embodiments, each side body portion 22 may be provided with a plurality of fittings 30, but preferably, each side body portion 22 is only provided with one fitting 30.

[0047] In this way, when the integrally injection-molded collision avoidance plate 20 is installed on the floor sweeping robot body 10, the elastic limiting member 40 fixed on the floor sweeping robot body 10 is adapted to the fitting 30 on the collision avoidance plate 20. The collision avoidance plate 20 is restricted by the elastic limiting member 40, so that the two side body portions 22 that are deformed and spread out can be pulled closer to each other along the first direction, so as to have a definite position relative to the floor sweeping robot body 10. Therefore, the relative positional relationship between the collision avoidance plate 20 and the collision switch installed on the floor sweeping robot body 10 can be determined to ensure that the collision switch is in an initial state, and further, the accuracy of the collision avoidance plate 20 triggering the collision switch is high.

[0048] In addition, it should be noted that when the side body part 22 on one side of the anti-collision plate 20 collides with surrounding obstacles and moves backward, that is, moves in the direction close to the side body part 22 on the other side, the force exerted by the fitting 30 of this side body part 22 on the elastic limiting member 40 decreases, the elastic deformation of the elastic limiting member 40 decreases, while the side body part 22 on the other side moves in the direction away from the side body part 22 on the other side, making the force exerted by the fitting 30 on the elastic limiting member 40 increase accordingly, and the elastic deformation of the elastic limiting member 40 increases. The backward movement resistance of the side body part 22 on the impacted side is small, and further, the pressure exerted by the side body part 22 on the corresponding collision switch is sufficient, and the collision switch can be triggered in time, improving the triggering sensitivity of the collision switch.

[0049] In contrast, if a non-elastic limiting structure is adapted to the fitting 30, when the side body part 22 on the impacted side moves backward, while the side body part 22 on the other side is restricted by the non-elastic limiting structure, and due to the small elastic deformation of the integrally formed anti-collision plate 20, the backward movement resistance of the side body part 22 on the impacted side is large, resulting in insufficient backward movement amount of the side body part 22 on the impacted side, and further, the pressure exerted on the collision switch is insufficient, causing the collision switch to not be triggered sensitively, affecting the sensing of obstacles on both sides of the whole machine.

[0050] In summary, the floor cleaning robot 100 of the present application can not only make the two deformed and outwardly expanded side body parts 22 approach each other along the first direction to have a definite position relative to the floor cleaning robot body 10, so that the accuracy of the anti-collision plate 20 triggering the collision switch is high, but also can improve the triggering sensitivity of the collision switch.

[0051] Please refer to again Figure 2 , in the embodiment of the present application, the floor cleaning robot body 10 includes a housing 11. Specifically, the housing 11 includes an upper housing assembly, a lower housing and a bottom cover, and the elastic limiting member 40 is fixed to the upper housing assembly. The upper housing assembly, the lower housing and the bottom cover enclose to form an installation cavity for installing components of the floor cleaning robot 100, such as a dust suction component, a mopping component, a main controller and a battery, etc.

[0052] In some embodiments, the elastic limiting member 40 is arranged on one surface of the floor cleaning robot body 10 along the fourth direction, wherein the first direction, the fourth direction and the traveling direction of the floor cleaning robot 100 are perpendicular to each other in pairs. Specifically, the fourth direction is the vertical direction. Preferably, the elastic limiting member 40 is arranged on the upper surface of the floor cleaning robot body 10 along the vertical direction. In this way, space is provided for the elastic deformation of the elastic limiting member 40, and it is convenient for the fitting 30 on the anti-collision plate 20 to be adapted to the corresponding elastic limiting member 40, and the assembly process is simpler.

[0053] In some embodiments, the anti-collision plate 20 has a convex portion 23 circumferentially arranged along the edge and protruding towards the body 10 of the floor cleaning robot. The body 10 of the floor cleaning robot has a recessed portion 111 indented inward. The convex portion 23 can be received in the recessed portion 111. The elastic limiting member 40 is disposed in the recessed portion 111, and the engaging member 30 is disposed on the convex portion 23. Specifically, the recessed portion 111 is disposed on the housing 11. Disposing the elastic limiting member 40 in the recessed portion 111 and the engaging member 30 on the convex portion 23 provides a deformation space for the elastic limiting member 40 to elastically deform in the first direction. Specifically, the recessed portion 111 is disposed on the upper surface of the body 10 of the floor cleaning robot in the vertical direction.

[0054] Please refer to again Figure 4 , further, the elastic limiting member 40 includes a cantilever 41. The cantilever 41 extends in a second direction intersecting the first direction. The cantilever 41 includes a fixed end and a suspended end oppositely arranged in the second direction. The fixed end is fixedly connected to the body 10 of the floor cleaning robot, and the elastic limiting member 40 abuts against the engaging member 30 at the suspended end. The structure for the cantilever 41 to deform in the first direction is simple by setting. Preferably, the second direction is perpendicular to the first direction. Specifically, the second direction is the Figure 1 vertical direction shown in.

[0055] Furthermore, the body 10 of the floor cleaning robot is provided with a first limiting portion 12 and a second limiting portion 13 oppositely arranged in the first direction. The cantilever 41 is limited between the first limiting portion 12 and the second limiting portion 13 in the first direction. By setting the first limiting portion 12 and the second limiting portion 13, while providing sufficient deformation space for the cantilever 41 in the first direction, the deformation limit of the cantilever 41 is also protected, avoiding the cantilever 41 from being damaged due to excessive deformation and fracture.

[0056] Specifically, in an embodiment, the body 10 of the floor cleaning robot is provided with a limiting groove 14. The cantilever 41 is located in the limiting groove 14. Two inner walls of the limiting groove 14 oppositely arranged in the first direction serve as the first limiting portion 12 and the second limiting portion 13. By setting the limiting groove 14, on the one hand, the cantilever 41 can be received in the limiting groove 14, making the structure of the floor cleaning robot 100 more compact. In addition, as the inner walls of the limiting groove 14, the first limiting portion 12 and the second limiting portion 13 can improve the structural stability of the first limiting portion 12 and the second limiting portion 13, and the limiting is more reliable.

[0057] In some embodiments, the elastic limiting member 40 further includes a first abutting portion 42. The first abutting portion 42 is provided at the suspended end and extends along a third direction. 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 pairwise. Specifically, the third direction is the vertical direction. By providing the first abutting portion 42 extending along the third direction, the abutting area against the mating member 30 can be increased, so that the two side body portions 22 that are deformed and expanded can be reliably pulled closer to each other along the first direction.

[0058] Furthermore, the thickness of the first abutting portion 42 along the first direction is greater than the thickness of the cantilever 41 along the first direction. Specifically, the first abutting portion 42 and the cantilever 41 can be combined into an L shape. In this way, the structural strength of the first abutting portion 42 can be enhanced to improve the reliability of the abutment between the first abutting portion 42 and the mating member 30.

[0059] Please refer to again Figure 5 , in some embodiments, the mating member 30 includes a second abutting portion 31. The second abutting portion 31 extends along the third direction. The elastic limiting member 40 and the mating member 30 abut against each other through the first abutting portion 42 and the second abutting portion 31. By providing the abutment between the first abutting portion 42 and the second abutting portion 31 that both extend along the third direction, the position interference between the floor cleaning robot body 10 and the anti-collision plate 20 in a plane parallel to the first direction can be minimized, and the collision sensing of the anti-collision plate 20 can be improved.

[0060] Furthermore, the anti-collision plate 20 has a side wall 24 along the circumferential direction. The mating member 30 further includes a reinforcing portion 32. The second abutting portion 31 is spaced from the side wall 24 along the first direction. The reinforcing portion 32 extends along the first direction, and both ends of the reinforcing portion along the first direction are respectively connected to the second abutting portion 31 and the side wall 24. Specifically, the side wall 24 is provided on the convex portion 23. In a specific embodiment, the second abutting portion 31 extends along the second direction. Further, there may be a plurality of reinforcing portions 32, and the plurality of reinforcing portions 32 are spaced along the second direction. In this way, the structural strength of the mating member 30 can be improved to be stably adapted to the elastic limiting member 40.

[0061] Furthermore, the side of the second abutting portion 31 away from the reinforcing portion 32 is connected to the side wall 24, and the side wall, the second abutting portion 31, and the reinforcing portion 32 enclose a ring structure. Specifically, one end of the second abutting portion 31 along the second direction is connected to one end of the reinforcing portion 32 along the first direction, and the other end of the second abutting portion 31 along the second direction is connected to the side wall 24. The side wall, the second abutting portion 31, and the reinforcing portion 32 enclose a ring structure. Through the enclosed ring structure, the structural strength of the mating member 30 can be further improved.

[0062] In some embodiments, the elastic limiting member 40 is integrally formed with the housing 11 of the floor cleaning robot body 10. In some other embodiments, the mating member 30 is integrally formed with the side body portion 22. In other embodiments, the elastic limiting member 40 is integrally formed with the housing 11 of the floor cleaning robot body 10, and the mating member 30 is integrally formed with the side body portion 22. In this way, the structures of the floor cleaning robot body 10 and the anti-collision plate 20 can be simplified. Specifically, the housing 11 and the anti-collision plate 20 can be made of ABS plastic.

[0063] The floor cleaning robot 100 provided by the embodiments of the present application has the following beneficial effects:

[0064] When the integrally injection-molded anti-collision plate 20 is installed on the floor cleaning robot body 10, the elastic limiting member 40 fixed on the floor cleaning robot body 10 is adapted to the mating member 30 on the anti-collision plate 20. The anti-collision plate 20 is restricted by the elastic limiting member 40, so that the two deformed and outwardly expanded side body portions 22 can be pulled closer to each other along the first direction to have a definite position relative to the floor cleaning robot body 10. Therefore, the relative positional relationship between the anti-collision plate 20 and the collision switch installed on the floor cleaning robot body 10 can be determined to ensure that the collision switch is in an initial state, and further, the accuracy of the anti-collision plate 20 triggering the collision switch is high.

[0065] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
