[0036] As Figure 1As shown, in the related art, the mop assembly 10 of the sweeping robot comprises a mop base plate 11, a support 12 and a driving motor, the driving motor drives the mop base plate 11 to move relative to the support 12. Among them, an elastic connecting part 13 is arranged between the mop base plate 11 and the support 12 to limit the moving direction of the mop base plate 11. However, the elastic connecting part 13 is composed of a structure similar to a rectangular frame, connection holes are opened at the ends of the elastic connecting part 13 close to the mop base plate 11 and the support 12, and the elastic connecting part 13 is connected to the mop base plate 11 and the support 12 respectively through screws arranged in the corresponding connection holes. This structure needs to be connected to the mop base plate 11 and the support 12 respectively by using screws, and the assembly operation is complicated. In addition, the deformation space of the elastic connecting part 13 with a rectangular frame structure is large, which makes it difficult to limit the movement of the mop base plate 11.

[0037] As shown in Figure 2 To solve the above problems, embodiments of the present application provide a flexible connecting piece 100, mainly used for cleaning robots.

[0038] As shown in Figure 6 The cleaning robot has a vibrating mop assembly 200, the vibrating mop assembly 200 comprises a mop body 210 and a movable plate 220, the movable plate 220 reciprocates relative to the mop body 210, a part of the movable plate 220 is connected with a mop, and at the same time, the mop is connected with the mop body 210. The flexible connecting piece 100 is connected between the movable plate 220 and the mop body 210, and is used to limit the movement between the mop body 210 and the movable plate 220 of the cleaning robot.

[0039] As shown in Figure 3 and Figure 4 The flexible connecting piece 100 comprises a flexible main body 110 and an elastic body 120.

[0040] Among them, the flexible main body 110 has oppositely arranged first and second faces 1101 and 1102, at least one of the first and second faces 1101 and 1102 is provided with an anti-skid part 112, and the flexible main body 110 is further provided with a connecting part 111 for connecting with the movable plate 220. The elastic body 120 is arranged on the side of the flexible main body 110 away from the connecting part 111, so that the connecting part 111 is connected with the movable plate 220, and the elastic body 120 abuts against the mop body.

[0041] It should be noted that the flexible main body 110 and the elastic body 120 are made of soft material, such as soft rubber or silicone. It can be understood that the anti-skid part 112 is also made of soft material. Of course, in other embodiments, the flexible main body 110 and the elastic body 120 can also be made of other soft materials.

[0042] Optionally, the flexible body 110 is integrally formed with the elastic body 120. Of course, the flexible body 110 and the elastic body 120 can also be connected in a split manner.

[0043] The flexible connector 100 provided by the embodiment of the present application can increase the friction between the flexible body 110 and the mop body 210 by arranging the first surface 1101 and the second surface 1102 on opposite sides of the flexible body 110 and arranging the anti-skid part 112 on at least one of the first surface 1101 and the second surface 1102, the anti-skid part 112 can abut against the mop body 210 or the movable plate 220 of the cleaning robot to increase the friction between the flexible body 110 and the mop body 210, facilitate the restriction of the movement of the movable plate 220, and realize the movement of the movable plate 220 in a smaller space. Meanwhile, the connecting part 111 is used to connect with the movable plate 220, and the elastic body 120 can abut against the mop body 210 to further restrict the movement of the movable plate 220, so that the movable plate 220 can move in a smaller range, thereby driving the mop to move, that is, realizing the reciprocating wiping of the mop on the surface to be cleaned, and improving the cleaning effect.

[0044] As shown in Figure 2 In one embodiment, the elastic body 120 is optionally provided with a groove 121. In this way, when the movable plate 220 moves in the width direction of the mop body 210, the elastic body 120 provided with the groove 121 can provide a space for the elastic deformation of the elastic body 120 when the elastic body 120 is elastically deformed, and the groove 121 is arranged to facilitate the deformation of the elastic body 120.

[0045] It can be understood that when the movable plate 220 moves in the length direction of the mop body 210, the elastic body 120 and the flexible body 110 will also elastically deform to a certain extent, and the anti-skid part 112 will also generate a force opposite to the moving direction of the movable plate 220 at any time, thereby restricting the movement of the movable plate 220 while ensuring the slight movement of the movable plate 220, and facilitating the wiping of the mop.

[0046] Continuing to refer to Figure 2 and Figure 3 In the above embodiment in which the elastic body 120 is provided with the groove 121, further, the elastic body 120 is provided with a partition rib 122, and the partition rib 122 divides the groove 121 into a first groove body 1211 and a second groove body 1212.

[0047] In this embodiment, the partition rib 122 divides the groove 121 into the first groove body 1211 and the second groove body 1212, so that when the movable plate 220 moves in the width direction of the mop body 210, the elastic body 120 is compressed to deform, and the partition rib 122 can bend into the first groove body 1211 or the second groove body 1212, thereby facilitating the deformation of the elastic body 120.

[0048] Further, the outer groove walls of the first groove 1211 and the second groove 1212 are respectively in arc-shaped structures 1213. The arc-shaped surfaces of the arc-shaped structures 1213 of the first groove 1211 abut against the dolly body 210, and the arc-shaped surfaces of the arc-shaped structures 1213 of the second groove 1212 also abut against the dolly body 210. In this way, when the movable plate 220 moves in the width direction of the dolly body 210, the arc-shaped structures 1213 of the first groove 1211 and the second groove 1212 are easily compressed and deformed, and at the same time, an opposite force is formed in the direction opposite to the deformation direction. In addition, when the movable plate 220 moves in the length direction of the dolly body 210, the two arc-shaped structures 1213 are arranged in the length direction of the movable plate 220 with a certain friction force, further limiting the movement range of the movable plate 220.

[0049] In the above embodiment, further, the outer groove walls of the first groove 1211 and the second groove 1212 are connected by a circular arc, the center of the circular arc is located outside the first groove 1211 or the second groove 1212, and the center of the arc-shaped structure 1213 is located inside the first groove 1211 or the second groove 1212. In this way, a concave section in the direction of the flexible body 110 is formed between the arc-shaped structure 1213 of the first groove 1211 and the arc-shaped structure 1213 of the second groove 1212, that is, the position of the circular arc connection. In this way, when the movable plate 220 moves in the length direction of the dolly body 210, the arc-shaped structures 1213 of the first groove 1211 and the second groove 1212 are deformed in the length direction of the dolly body 210. Due to the circular arc connection, the connection between the two arc-shaped structures 1213 is avoided from being broken due to repeated deformation, and the reliability of the product is improved.

[0050] In the embodiment where the elastic body 120 has the partitioning ribs 122 and the arc-shaped structures 1213, optionally, the length d of the partitioning ribs 122 away from the flexible body 110 is less than the corresponding radius of the arc-shaped structures 1213. That is, the length d of the partitioning ribs 122 is less than the distance from the position where the arc-shaped structures 1213 abut against the mop body to the center of the corresponding circle of the arc-shaped structures 1213. In this way, the first groove 1211 and the second groove 1212 are substantially arc-shaped grooves, and the arc-shaped structures 1213 of the first groove 1211 and the second groove 1212 are disconnected, that is, there is a gap between the two arc-shaped structures 1213. On the one hand, when the movable plate 220 moves in the width direction of the mop body 210, the arc-shaped structures 1213 of the first groove 1211 and the second groove 1212 are compressed and deformed, which is easy to deform. On the other hand, when the movable plate 220 moves in the length direction of the mop body 210, the gap between the two arc-shaped structures 1213 increases the friction between the two arc-shaped structures 1213 and the mop body, thereby increasing the reaction force on the movable plate 220 and easily limiting the movement of the movable plate 220.

[0051] As shown in Figure 1 , Figure 4 and Figure 5 , in any one of the above embodiments, optionally, the flexible body 110 forms a plurality of strip-shaped protrusions 1121 in the direction of the first surface 1101 or the second surface 1102, and the plurality of strip-shaped protrusions 1121 are arranged at intervals in the first direction and define the anti-slip portion 112.

[0052] It should be noted that, for ease of explanation, the first surface 1101 is set as the surface facing the mop body 210, and the second surface 1102 is the opposite surface.

[0053] It can be understood that, as the plurality of strip-shaped protrusions 1121 are arranged at intervals on the first surface 1101 of the flexible body 110 to define the anti-slip portion 112. In this way, when the plurality of strip-shaped protrusions 1121 abut against the mop body 210, the plurality of strip-shaped protrusions 1121 have a certain frictional force on the mop body 210 when the movable plate 220 moves in the length direction of the mop body 210, which hinders the movement of the movable plate 220 and further limits the movement range of the movable plate 220.

[0054] Of course, in other embodiments, the plurality of strip-shaped protrusions 1121 can also be arranged at intervals on the second surface 1102 of the flexible body 110 to define the anti-slip portion 112.

[0055] As shown in Figure 2As shown, both the first surface 1101 and the second surface 1102 are provided with the anti-slip portion 112. That is, multiple strip-shaped protrusions 1121 are provided on both the first surface 1101 and the second surface 1102 of the flexible body 110, and the multiple strip-shaped protrusions 1121 are spaced apart to define and form the anti-slip portion 112, so that each surface has an anti-slip portion 112.

[0056] like Figure 2 and Figure 5 As shown, in the embodiment of the strip protrusion 1121 described above, the strip protrusion 1121 is further provided with a blind hole 11211 along the second direction, and the first direction is perpendicular to the second direction.

[0057] In this embodiment, the strip protrusion 1121 is provided with blind holes 11211. In this way, when the movable plate 220 moves along the length direction of the slide body 210, the blind holes 11211 of the strip protrusion 1121 will deform along with the movement of the movable plate 220. For example, the blind holes 11211 will deform from circular blind holes 11211 to elliptical blind holes 11211. This makes the strip protrusion 1121 have both friction and a certain elastic deformation force, which is more conducive to the flexible connector 100 restricting the movement of the movable plate 220, while ensuring that the movable plate 220 can move.

[0058] It should be noted that the first direction is the length direction of the movable plate 220, and the second direction is the width direction of the movable plate 220.

[0059] It is understandable that if the movable plate 220 is a rectangular plate, then the length direction of the movable plate 220 is the first direction, and the width direction of the movable plate 220 is the second direction.

[0060] like Figure 5 As shown, in any of the above embodiments, optionally, the flexible body 110 has a slot along the second direction, and the slot forms the connecting portion 111.

[0061] In this embodiment, the connecting part 111 is a slot. It can be understood that the movable plate 220 is provided with a slot plate 221 corresponding to the slot. The slot plate 221 is connected to the slot. This facilitates the assembly of the flexible connector 100 and the movable plate 220, avoiding the problem of difficult operation and reduced assembly efficiency caused by connecting with screws in the prior art. In this embodiment, the connection method of the slot plate 221 and the slot facilitates operation and improves assembly efficiency.

[0062] like Figure 6 and Figure 7 As shown, embodiments of this application also provide a cleaning robot, which includes the flexible connector 100 described in any of the above embodiments.

[0063] Optionally, the cleaning robot comprises a vibrating mop assembly 200, the vibrating mop assembly 200 comprising a mop body 210 and a movable plate 220. The mop body 210 has a receiving groove 211; the movable plate 220 is located in the receiving groove 211 and can reciprocate relative to the mop body 210, and the movable plate 220 is provided with a first connecting part 111 at each of two opposite sides along the width direction of the movable plate 220. The driving member of the cleaning robot drives the movable plate 220 to move.

[0064] The elastic body 120 is arranged on the side of the flexible body 110 away from the connecting part 111, and the elastic body 120 abuts against the inner groove wall of the receiving groove 211.

[0065] It should be noted that the first connecting part 111 is a clamping plate 221, and the connecting part 111 of the flexible body 110 is a clamping groove, and the clamping plate 221 is clamped in cooperation with the clamping groove.

[0066] The cleaning robot provided by the embodiments of the present application has the flexible connecting part 100 described in any of the above embodiments, and thus has all the beneficial effects of the flexible connecting part 100 in any of the above embodiments, which will not be described herein.

[0067] For example, the flexible connecting part 100 comprises a flexible body 110 and an elastic body 120. The flexible body 110 is provided with a first face 1101 and a second face 1102 at opposite sides, and an anti-skid part 112 is arranged on at least one of the first face 1101 and the second face 1102, the anti-skid part 112 being capable of abutting against the mop body 210 or the movable plate 220 of the cleaning robot to increase the friction between the flexible body 110 and the mop body 210, so as to facilitate limiting the movement of the movable plate 220. Meanwhile, the connecting part 111 is used for connecting with the movable plate 220, and the elastic body 120 is capable of abutting against the mop body 210 to further limit the movement of the movable plate 220, so that the movable plate 220 can move in a smaller range, facilitating the mop connected with the movable plate 220 to wipe the cleaning surface and improving the cleaning effect.
