[0050] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings. The same parts are represented by the same figure numbers. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0051] like Figure 1-16 As shown, a mop structure provided by an embodiment of the utility model includes a housing 1 , a mop assembly 2 , an elastic driving member 3 and a first resetting mechanism 4 .

[0052] The bottom of the housing 1 has a storage groove 111 , and the mop assembly 2 includes a mounting bracket 21 and a mop 22 connected to the mounting bracket 21 .

[0053] The mounting bracket 21 is slidably connected to the housing 1 , and the mop 22 is slidably disposed in the storage groove 111 .

[0054] The elastic driving member 3 is connected between the housing 1 and the mounting bracket 21 , and is used to drive the mop assembly 2 to move so that one end of the mop 22 extends out of the storage groove 111 .

[0055] The first resetting mechanism 4 includes a first motor 41 , a first cable 43 , and a first rotating disk 42 mounted on the motor shaft of the first motor 41 and used for retracting and releasing the first cable 43 .

[0056] The first motor 41 is connected to the housing 1 , and the first cable 43 is connected between the first rotating disk 42 and the mounting bracket 21 .

[0057] The mop structure provided by the utility model includes a shell 1, a mop assembly 2, an elastic driving member 3 and a first reset mechanism 4. The shell 1 can be assembled or integrated with the shell of the sweeping robot. The bottom of the shell 1 has a storage groove 111, which extends along the left and right directions of the sweeping robot, that is, it is arranged perpendicular to the forward direction of the sweeping robot. Specifically, the storage groove 111 is provided at the bottom of the shell body 11. The storage groove 111 is used to store the mop 22 of the mop assembly 2. The mop assembly 2 includes a mounting bracket 21 and a mop 22, and the mop 22 is connected to the mounting bracket 21. The mop 22 is preferably a roller mop, which can be stored in the storage groove 111. The connecting portion of the mounting bracket 21 is slidably connected to the shell 1, and the mop 22 can move and retract along the storage groove 111. In normal state, the mop 22 is stored in the storage groove 111, and the two ends of the mop 22 will not extend out of the storage groove 111. When it is necessary to clean the corners, the mop 22 can be driven to move toward one end of the storage groove 111 so that one end of the mop 22 extends out of the storage groove 111, thereby facilitating cleaning of the corners.

[0058] The elastic driving member 3 is connected between the housing 1 and the mounting bracket 21, and is used to drive the mop assembly 2 to move so that one end of the mop 22 extends out of the storage groove 111. The elastic driving member 3 can be a spring or a spring. Fig.11 As shown, one or both ends of the elastic driving member 3 are provided with a connecting frame 31 for connecting with the housing 1 and / or the mounting bracket 21. Fig.11 As shown, if the left end of the elastic driving member 3 is connected to the housing 1, and the connecting frame 31 at the right end of the elastic driving member 3 is connected to the mounting bracket 21, the elastic driving member 3 uses an expansion spring to push the mounting bracket 21 and the mop 22 to extend to the right. If the left end of the elastic driving member 3 is connected to the mounting bracket 21, and the connecting frame 31 at the right end of the elastic driving member 3 is connected to the housing 1, the elastic driving member 3 uses a compression spring to pull the mounting bracket 21 and the mop 22 to extend to the right.

[0059] The first resetting mechanism 4 includes a first motor 41, a first rotating disk 42 and a first cable 43. The first motor 41 is connected to the housing 1, the first rotating disk 42 is connected to the motor shaft of the first motor 41, and the first cable 43 is connected between the first rotating disk 42 and the mounting bracket 21. The first motor 41 can be a servo motor or a stepping motor. The first rotating disk 42 retracts and releases the first cable 43 to pull back the mounting bracket 21 and drive the mop 22 to reset, and is also used to release and loosen the mounting bracket 21, so that the mop 22 is extended under the action of the elastic driving member 3.

[0060] In the utility model, the first reset mechanism 4 is connected to the mounting bracket 21 of the mop assembly 2 by a flexible first cable 43. In the default state, the first motor 41 drives the first turntable 42 to rotate forward to retract the first cable 43, thereby overcoming the force of the elastic drive member 3, so that the mop 22 is in the initial position, stored in the storage slot 111, and does not extend out of the shell 1. When the mop 22 needs to be extended to clean the corners and edges, the first motor 41 drives the first turntable 42 to rotate in the opposite direction to release the first cable 43, and under the force of the elastic drive member 3, one end of the mop 22 extends out of the shell 1 to clean the corners and edges. When the mop 22 is in the extended state, the mop 22 is mainly extended by the force of the elastic drive member 3, and the first cable 43 is a flexible connection that does not hinder the telescopic movement or lateral movement of the mop 22. Therefore, when the end of the extended mop 22 encounters an obstacle, the elastic driving member 3 can be adaptively retracted and compressed to avoid the obstacle, thereby preventing the end of the mop 22 from hard collision with the obstacle, reducing the wear of the mop 22, and preventing the mop 22 from damaging household items, thereby improving the user experience.

[0061] In one embodiment, if Figure 6-7 and Fig.16 As shown, one end of the mop 22 has a mop end plate 23, and one end of the storage groove 111 is provided with a baffle 112 for stopping the mop end plate 23. The mop end plate 23 is slidably arranged on the outer side of the baffle 112.

[0062] In this embodiment, a mop end plate 23 is provided at one end of the mop 22, one end of the mop end plate 23 is connected to the mounting bracket 21, the mop end plate 23 covers one end of the mop 22, and the other end of the mop end plate 23 extends out of the mop 22 to act as a baffle.

[0063] A baffle 112 is provided at one end of the storage slot 111 for stopping the mop end plate 23. The baffle 112 can be a flat plate or an L-shaped plate. The baffle 112 is connected to the housing body 11.

[0064] The mop end plate 23 is slidably disposed on the outer side of the baffle 112. When the mop 22 is driven to retract into the storage slot 111, the baffle 112 blocks the mop end plate 23. When the mop 22 is driven to extend toward one end of the storage slot 111, the mop end plate 23 leaves the baffle 112 and slides outward.

[0065] In one embodiment, if Figure 7-9 and Fig.16 As shown, the mounting bracket 21 includes a mop bracket 211 connected to the mop 22 , a sliding bracket 212 slidably connected to the housing 1 , and a connecting bracket 213 connected between the sliding bracket 212 and the mop bracket 211 .

[0066] The housing 1 is provided with a slide groove 113 , and the sliding bracket 212 is slidably assembled in the slide groove 113 .

[0067] The elastic driving member 3 and the first cable 43 are connected to the sliding bracket 212 respectively.

[0068] In this embodiment, the mounting bracket 21 includes a mop bracket 211, a sliding bracket 212 and a connecting bracket 213. The mop bracket 211 is a crossbar structure, and the mop 22 is installed below the mop bracket 211. The housing 1 is provided with a slide groove 113, and the slide groove 113 is arranged parallel to the storage groove 111. The sliding bracket 212 is assembled in the slide groove 113 and can slide in the slide groove 113. The connecting bracket 213 is a connecting arm, which is connected between the sliding bracket 212 and the mop bracket 211. Two sets of connecting brackets 213 can be configured as needed.

[0069] One end of the elastic driving member 3 is connected to the housing 1, and the other end thereof is connected to the sliding bracket 212. One end of the first pulling cable 43 is connected to the first rotating disk 42, and the other end thereof is connected to the sliding bracket 212.

[0070] When the mop 22 needs to be extended, the first motor 41 drives the first rotating disk 42 to rotate forward to release the first pull rope 43. The elastic driving member 3 drives the sliding bracket 212 to move along the slide groove 113, and drives the mop 22 to move horizontally and extend through the connecting bracket 213 and the mop bracket 211. When the sliding bracket 212 contacts the groove wall at one end of the slide groove 113, it means that the mop 22 is extended to the right position.

[0071] When the mop 22 needs to be reset, the first motor 41 drives the first turntable 42 to rotate in the opposite direction to retract the first pull cable 43, overcome the effect of the elastic driving member 3, pull the driving sliding bracket 212 to reset along the slide groove 113, and drive the mop 22 to move horizontally and reset through the connecting bracket 213 and the mop bracket 211.

[0072] In one embodiment, if Fig.10As shown, one end of the connecting bracket 213 is connected to the sliding bracket 212 via a rotating shaft 214 , and an elastic pressing member 215 for pressing down the connecting bracket 213 is installed on the rotating shaft 214 and / or the sliding bracket 212 .

[0073] In this embodiment, the connecting bracket 213 is connected to the sliding bracket 212 via a rotating shaft 214, and the connecting bracket 213 can swing up and down by a certain amplitude relative to the sliding bracket 212, so that the mop 22 can swing up and down for lifting and lowering operations. An elastic pressing member 215 is installed on the rotating shaft 214 and / or the sliding bracket 212, which is used to press down the connecting bracket 213 to maintain the cleaning effect after the mop 22 is lowered to the ground. The elastic pressing member 215 can be a torsion spring connected to the rotating shaft 214, or it can be an elastic pressing sheet connected to the sliding bracket 212. One end of the elastic pressing member 215 presses on the connecting bracket 213, so that the connecting bracket 213 swings downward, increasing the pressure of the mop 22 mopping the floor.

[0074] In one embodiment, if Figure 1 and Figure 7 As shown, a second reset mechanism 5 for driving the mop cloth 22 to move upward and reset is installed between the housing 1 and the mop cloth assembly 2. The output end of the second reset mechanism 5 is connected to the bracket 213 and / or the mop cloth bracket 211.

[0075] In this embodiment, a second reset mechanism 5 is configured to lift the lowered mop cloth 22 off the ground. The second reset mechanism 5 can be a motor mechanism, a piston mechanism, etc. The second reset mechanism 5 is connected between the housing 1 and the mounting bracket 21 of the mop cloth assembly 2. Specifically, the output end of the second reset mechanism 5 is connected to the connecting bracket 213 and / or the mop cloth bracket 211.

[0076] When the mop cloth 22 is no longer needed for mopping the floor, the second reset mechanism 5 is used to pull up the connecting bracket 213 and / or the mop cloth bracket 211, thereby lifting the mop cloth 22 off the ground.

[0077] When the mop cloth 22 is needed to mop the floor, the second reset mechanism 5 releases the connecting bracket 213 and / or the mop cloth bracket 211 , and under the action of the elastic pressing member 215 , the mop cloth 22 drops to the ground.

[0078] In one embodiment, if Figure 8 and Fig.15 As shown, the second resetting mechanism 5 includes a second motor 51 , a second cable 53 , and a second rotating disk 52 installed on the motor shaft of the second motor 51 and used for retracting and releasing the second cable 53 .

[0079] The second motor 51 is connected to the housing 1 , and the second cable 53 is connected between the second rotating disk 52 and the connecting bracket 213 and / or the mop bracket 211 .

The second motor 51 is connected to the housing 1, the second rotating disk 52 is connected to the motor shaft of the second motor 51, and the second cable 53 is connected between the second rotating disk 52 and the connecting bracket 213 and / or the mop bracket 211. The second motor 51 can be a servo motor or a stepper motor. The second rotating disk 52 retracts and releases the second cable 53 to pull up the connecting bracket 213 and / or the mop bracket 211 and drive the mop 22 to rise and reset, and is also used to release the connecting bracket 213 and / or the mop bracket 211, so that the mop 22 descends to mop the floor under the action of the elastic pressing member 215.

[0081] In the present invention, the second reset mechanism 5 is connected to the connecting bracket 213 and / or the mop bracket 211 by a flexible second cable 53. When the mop 22 is in the state of descending to mop the floor, the mop 22 is mainly descended by the force of the elastic pressing member 215, and the second cable 53 is a flexible connection and will not hinder the up and down swinging of the mop 22. Therefore, when the extended mop 22 hits an obstacle protruding from the ground, it can adaptively move upward and compress the elastic pressing member 215, thereby crossing the obstacle, thereby improving the obstacle crossing performance of the product.
