[0060] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0061] The following refers to Figures 1 - 15 to describe a cleaning device and a cleaning system according to an embodiment of the present utility model.

[0062] Referring to Figures 1 - 15 , a cleaning device according to an embodiment of the present utility model includes: a device body 1, a first cleaning module 2, and a first driving assembly 3. The first cleaning module 2 and the first driving assembly 3 are both provided on the device body 1, and the first driving assembly 3 is used to drive the first cleaning module 2 to move relative to the device body 1.

[0063] The first cleaning module 2 includes a cleaning component 21 for cleaning the working surface. The cleaning component 21 has a retracted position and an extended position. The extended position is farther from the center of the extrusion device body 1 than the retracted position. The cleaning component 21 can swing relative to the device body 1 between the retracted position and the extended position. The cleaning range of the cleaning component 21 in the extended position is farther from the center. When in the retracted position, the cleaning component 21 is close to the center of the device body 1, and the cleaning range is small at this time. When the cleaning component 21 is in the extended position, the cleaning component 21 is away from the center of the device body 1, and the cleaning range is larger at this time. By enabling the cleaning position to swing between the retracted position and the extended position, it is beneficial to expand the overall cleaning range of the cleaning device according to the working needs of the cleaning device.

[0064] During the process of the first cleaning module 2 moving from the retracted position to the extended position, the first cleaning module 2 swings in a direction away from the center of the device body 1; during the process of the first cleaning module 2 moving from the extended position to the retracted position, the first cleaning module 2 swings in a direction close to the center of the device body 1.

[0065] The first driving assembly 3 includes a first driving motor 31 and a transmission assembly. The first driving motor 31 outputs power to drive the transmission assembly to move. The transmission assembly is drivably connected between the first driving motor 31 and the first cleaning module 2 to drive the cleaning component 21 to swing between the retracted position and the extended position. The transmission assembly includes an elastic member 321. The extended position is farther from the center of the device body 1 than the retracted position. The elastic member 321 serves as a transmission structure. The elastic member 321 can play a good buffering role and an adaptive adjustment role during the transmission process, so that the first driving assembly 3 can drive the cleaning component 21 to move more stably. The elastic member 321, as a part of the transmission assembly, plays a buffering role during the swinging process and helps to adapt to different cleaning requirements.

[0066] Optionally, the first cleaning module 2 can be a side brush module, and the cleaning component 21 includes a side brush; optionally, the first cleaning module 2 can also be a mopping module, and the cleaning component 21 includes a mop.

[0067] For example, when the cleaning device is a floor sweeping robot and the cleaning component 21 is a side brush module, when the cleaning device needs to clean the corner, the first driving assembly 3 drives the cleaning component 21 to swing from the retracted position to the extended position so that the cleaning component 21 can clean the corner area; after the cleaning component 21 completes the cleaning of the corner area, the first driving assembly 3 drives the cleaning component 21 to swing from the extended position to the retracted position.

[0068] Optionally, the cleaning component 21 has an active retraction mode and a passive retraction mode. In the active retraction mode, the first drive motor 31 is used to drive the cleaning component 21 to swing from the extended position to the retracted position. In the passive retraction mode, when the first drive motor 31 stops working, the cleaning component 21 moves from the extended position to the direction close to the retracted position under the action of the obstacles outside the cleaning device. The setting of the elastic member 321 enables the cleaning component 21 to overcome the elastic force of the elastic member 321 and move from the extended position to the direction close to the retracted position in the passive retraction mode when the cleaning device hits an external obstacle. The elastic member 321 can absorb the impact to reduce or avoid damage or jamming of the cleaning device. In addition, when the cleaning device bypasses the obstacle, the cleaning component 21 can automatically return to the extended position under the recovery action of the elastic member 321 so that the cleaning component 21 continues to clean. The setting of the elastic member 321 can also reduce or avoid the collision of obstacles causing changes in the body state or body position of the cleaning device.

[0069] According to the cleaning device of the embodiment of the utility model, by setting a first driving assembly 3 including a first driving motor 31 and a transmission assembly, and making the transmission assembly include an elastic member 321, the first driving assembly 3 can drive the cleaning component 21 to swing between the retracted position and the swing-out position according to the working needs of the cleaning device, and when the cleaning component 21 swings to the swing-out position, the cleaning range can be expanded toward the outside of the cleaning device, so that the cleaning component 21 can clean the corners and other areas that the device body 1 cannot reach, so as to reduce or avoid the cleaning dead corners of the cleaning device during the cleaning process. In addition, the setting of the elastic member 321 also makes it possible for the cleaning component 21 to be in the outward swing position, if the cleaning component 21 encounters a collision with an obstacle, it can be swung toward the retracted position by compressing the elastic member 321, so as to avoid damage to the cleaning device due to collision or avoid the cleaning device from being unable to operate normally due to the obstruction of obstacles.

[0070] refer to Figures 1 - 4 According to some embodiments of the present invention, the transmission assembly includes a rotatable first transmission member 322, an elastic member 321 is connected between the first drive motor 31 and the first transmission member 322, the elastic member 321 is used to transmit the driving force of the first drive motor 31 to the first transmission member 322, and the first transmission member 322 is connected to the cleaning component 21 to drive the cleaning component 21 to swing between a retracted position and a swing-out position around the rotation axis of the first transmission member 322.

[0071] Optionally, the first transmission member 322 is directly or indirectly connected to the cleaning component 21 , so that the cleaning component 21 can swing around the rotation axis of the first transmission member 322 between the retracted position and the extended position.

[0072] Optionally, the elastic member 321 may be a tension spring, a torsion spring, etc.

[0073] By making the transmission assembly include a rotatable first transmission member 322 and connecting the first transmission member 322 to the cleaning member 21, after the first driving motor 31 transmits the driving force to the first transmission member 322 through the elastic member 321, the first transmission member 322 can rotate around its rotation axis, so as to drive the cleaning member 21 to swing around the rotation axis of the first transmission member 322 together with it. The first transmission member 322 can convert the power from the first driving motor 31 transmitted by the elastic member 321 into a swinging motion of the cleaning member 21 between the retracted position and the swung-out position.

[0074] Reference Figures 1 - 13 , according to some alternative embodiments of the present invention, the rotation axis of the first transmission member 322 is the first rotation axis, and there is a second positional relationship and a third positional relationship between the elastic member 321 and the first rotation axis.

[0075] Wherein, in the second positional relationship, the elastic force of the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first rotation axis close to the center of the device body 1; in the third positional relationship, the elastic force of the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first rotation axis far from the center of the device body 1.

[0076] When the cleaning member 21 is in the retracted position, the elastic member 321 is in the second positional relationship; when the cleaning member 21 is in the swung-out position, the elastic member 321 is in the third positional relationship.

[0077] When the cleaning member 21 is in the retracted position, the elastic member 321 is in the second positional relationship with the first rotation axis. The elastic force of the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first rotation axis close to the center of the device body 1. At this time, the elastic force of the elastic member 321 can provide a tangential pulling force for the first transmission member 322. This tangential pulling force makes the first transmission member 322 tend to rotate towards the center of the device body 1, so that the cleaning member 21 connected to the first transmission member 322 has a tendency to rotate towards the center of the device body 1, thereby enabling the cleaning member 21 to be stably maintained in the retracted position.

[0078] By making there be a second positional relationship and a third positional relationship between the elastic member 321 and the first rotation axis, and enabling the first transmission member 322 to drive the cleaning member 21 to swing between the retracted position and the swung-out position through the change of the positional relationship between the elastic member 321 and the first rotation axis, the elastic force effect of different positional relationships of the elastic member 321 is used to assist the movement of the cleaning member 21, thereby effectively adjusting the cleaning range, improving the cleaning efficiency, and also increasing the stability and durability of the system.

[0079] Reference Figures 1 - 13 According to some alternative embodiments of the present utility model, there is also a first positional relationship between the elastic member 321 and the first rotation axis. In this first positional relationship, the elastic force of the elastic member 321 passes through the first rotation axis; when the cleaning member 21 is in the retracted position, the elastic member 321 can also be in the first positional relationship.

[0080] When the elastic member 321 and the first rotation axis are in the first positional relationship, the elastic force of the elastic member 321 passes through the first rotation axis. At this time, the elastic force of the elastic member 321 will not provide a rotational tangential force for the first transmission member 322 by passing through the rotation center of the first transmission member 322. When the cleaning member 21 is in the retracted position and the elastic member 321 is in the first positional relationship, the cleaning member 21 is in a critical state of moving from the retracted position towards the deployed position.

[0081] By making there be a first positional relationship between the elastic member 321 and the first rotation axis, the relative positional relationship between the elastic member and the first rotation axis can be stably transformed between the second positional relationship and the third positional relationship.

[0082] Optionally, when the positional relationship between the elastic member 321 and the first rotation axis is switched from the first positional relationship to the third positional relationship, the acting force of the elastic member 321 gradually changes from the state of passing through the first rotation axis to the state of being spaced apart from the first rotation axis, and is located on the side of the first rotation axis far from the center of the device body 1. During the process that the acting force of the elastic member 321 gradually becomes spaced apart from the first rotation axis, the acting force of the elastic member 321 can provide a tangential tension for the first transmission member 322, and this tangential tension causes the first transmission member 322 to rotate in a direction away from the center of the device body 1, so that the first transmission member 322 drives the cleaning member 21 to swing from the retracted position in a direction away from the center of the device body 1 until the cleaning member 21 swings to the deployed position.

[0083] For example, the cleaning device is a floor-sweeping robot, and the cleaning component 21 is a side brush module. In the initial state, the cleaning component 21 is in the retracted position, and the acting force of the elastic member 321 and the first rotation axis are in a second positional relationship. When the cleaning device needs to clean a corner, the first driving motor 31 rotates in the forward direction and transmits the driving force to the transmission assembly, causing the elastic member 321 to change its position. The positional relationship between the acting force of the elastic member 321 and the first rotation axis first changes from the second positional relationship to the first positional relationship, and then changes from the first positional relationship to the third positional relationship. During the process of changing from the first positional relationship to the third positional relationship, the acting force of the elastic member 321 provides a tangential pulling force for the first transmission member 322 to rotate in a direction away from the center of the device body 1, so that the first transmission member 322 drives the cleaning component 21 to swing from the retracted position to the extended position in a direction away from the center of the device body 1, so as to enable the cleaning component 21 to clean the corner area.

[0084] After the cleaning component 21 finishes cleaning the corner area, the first driving motor 31 rotates in the reverse direction and transmits the driving force to the transmission assembly, causing the elastic member 321 to change its position. The positional relationship between the acting force of the elastic member 321 and the first rotation axis first changes from the third positional relationship to the first positional relationship, and then changes from the first positional relationship to the second positional relationship. During the process of changing from the first positional relationship to the second positional relationship, the acting force of the elastic member 321 provides a tangential pulling force for the first transmission member 322 to rotate in a direction close to the center of the device body 1, so that the first transmission member 322 drives the cleaning component 21 to swing from the extended position to the retracted position in a direction close to the center of the device body 1.

[0085] Reference Figures 1 - 15 According to some optional embodiments of the present invention, the elastic member 321 is a tension spring. By making the elastic member 321 a tension spring, the arrangement of the elastic member 321 formed as a tension spring is simple and can achieve stable transmission.

[0086] Reference Figures 1 - 9, according to some alternative embodiments of the present utility model, the transmission assembly includes a second transmission member 323. The second transmission member 323 is rotatably connected to the device body 1, and the second transmission member 323 is drivably connected to the motor shaft of the first drive motor 31. An elastic member 321 is connected between the first transmission member 322 and the second transmission member 323. The function of the elastic member 321 connected between the first transmission member 322 and the second transmission member 323 is to transmit force and torque and provide buffering between the first transmission member 322 and the second transmission member 323. The presence of the elastic member 321 makes the entire transmission process smoother. At the same time, it can also adjust the position of the cleaning member 21 under different positional relationships to adapt to different cleaning requirements. Optionally, when the first drive motor 31 is started, the motor shaft starts to rotate and drives the second transmission member 323 to rotate by a certain means (such as gears, linkages, belts or chains, etc.).

[0087] Optionally, the second transmission member 323 is directly drivably connected to the motor shaft of the first drive motor 31; optionally, the second transmission member 323 is indirectly drivably connected to the motor shaft of the first drive motor 31.

[0088] By making the transmission assembly include the second transmission member 323, the second transmission member 323 can stably transmit the driving force of the first drive motor 31 to the elastic member 321, so as to further drive the cleaning member 21 to swing between the retracted position and the extended position. For example, the second transmission member 323 converts the rotational motion of the first drive motor 31 into a position change of the elastic member 321, so that the position relationship between the elastic member 321 and the first rotation axis changes. The elastic member 321 has a first positional relationship, a second positional relationship, and a third positional relationship with the first rotation axis. During the process of the change in the positional relationship of the elastic member relative to the first rotation axis, the elastic member drives the cleaning assembly to swing between the retracted position and the extended position.

[0089] Reference Figures 1 - 9 , according to some alternative embodiments of the present utility model, the first transmission member 322 and the second transmission member 323 are coaxially arranged. By making the first transmission member 322 and the second transmission member 323 coaxially arranged, the transmission relationship between the first transmission member 322 and the second transmission member 323 is simple, reducing the energy loss during the power transmission process. The coaxial arrangement helps to reduce the unbalanced torque caused by different axes, thereby improving the stability of the entire system and enabling the cleaning member 21 to stably swing between the retracted position and the extended position.

[0090] Reference Figures 1 - 9, according to some alternative embodiments of the present utility model, the first transmission member 322 and the second transmission member 323 are arranged at intervals along the axial direction of the first transmission member 322. In the axial direction of the first transmission member 322, the elastic member 321 is located between the first transmission member 322 and the second transmission member 323. By arranging the first transmission member 322 and the second transmission member 323 at intervals along the axial direction of the first transmission member 322, interference between the first transmission member 322 and the second transmission member 323 during rotation can be avoided, and the elastic member 321 is located between the first transmission member 322 and the second transmission member 323 in the axial direction of the first transmission member 322. Such an arrangement makes the positional layout among the first transmission member 322, the second transmission member 323, and the elastic member 321 reasonable and the structure compact, facilitating the connection of the elastic member 321 between the first transmission member 322 and the second transmission member 323.

[0091] Reference Figures 1 - 15 , according to some alternative embodiments of the present utility model, a first mounting post 41 is provided at the radially outer end of the first transmission member 322. The first mounting post 41 is located on one axial side of the first transmission member 322. A second mounting post 51 is provided at the radially outer end of the second transmission member 323. The second mounting post 51 is located on one axial side of the second transmission member 323. Both ends of the elastic member 321 respectively have a first hook portion 42 and a second hook portion 52. The first hook portion 42 is sleeved on the first mounting post 41, and the second hook portion 52 is sleeved on the second mounting post 51. Through the cooperation of the first mounting post 41 and the first hook portion 42 and the cooperation of the second mounting post 51 and the second hook portion 52, such an arrangement is beneficial to stably connecting the elastic member 321 between the first transmission member 322 and the second transmission member 323, thereby facilitating stable power transmission of the elastic member 321 between the first transmission member 322 and the second transmission member 323.

[0092] Optionally, the second transmission member 323 can be a swing rod. One end of the swing rod is fixedly connected to the motor shaft of the first drive motor 31, and the other end of the swing rod is provided with a second mounting post 51. The elastic member 321 is connected to the second transmission member 323 through the second mounting post 51.

[0093] For example, when the cleaning component 21 is in the retracted position and the elastic member 321 and the first rotation axis are in a second positional relationship, the first drive motor 31 rotates in the forward direction. The first drive motor 31 drives the second transmission member 323 to rotate. The second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning component 21 remains in the retracted position;

[0094] Next, the first drive motor 31 continues to rotate in the forward direction. The first drive motor 31 continues to drive the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position. As a result, the positional relationship between the elastic member 321 and the first rotation axis gradually changes from the first positional relationship to the third positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 away from the center of the device body 1, so that the acting force of the elastic member 321 can provide a torque for the first transmission member 322 to drive the cleaning device to rotate away from the device body 1, so that the cleaning component 21 can be swung out from the retracted position to the swung-out position.

[0095] For example, when the cleaning component 21 is in the swung-out position and the elastic member 321 and the first rotation axis are in the third positional relationship, the first drive motor 31 rotates in the reverse direction. The first drive motor 31 drives the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning component 21 remains in the swung-out position;

[0096] Next, the first drive motor 31 continues to rotate in the reverse direction. The first drive motor 31 continues to drive the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position. As a result, the positional relationship between the elastic member 321 and the first rotation axis gradually changes from the first positional relationship to the second positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 close to the center of the device body 1, so that the acting force of the elastic member 321 can provide a torque for the first transmission member 322 to drive the cleaning device to rotate towards the device body 1, so that the cleaning component 21 can be swung out from the swung-out position to the retracted position.

[0097] According to some optional embodiments of the present invention, the transmission assembly further includes a third transmission member 324. The third transmission member 324 is fixed to the motor shaft of the first drive motor 31 and meshes with the second transmission member 323. Optionally, the second transmission member 323 and the third transmission member 324 are directly meshed or indirectly meshed. By providing the third transmission member 324 fixed to the motor shaft of the first drive motor 31 and making the third transmission member 324 mesh with the second transmission member 323, the driving force of the first drive motor 31 can be stably and efficiently transmitted to the second transmission member 323 through the third transmission member 324.

[0098] Reference Figures 1 - 13, according to some alternative embodiments of the present utility model, the second transmission member 323 is a half gear, and the third transmission member 324 is a gear. By making the second transmission member 323 a half gear and the third transmission member 324 a gear, power transmission between the second transmission member 323 and the third transmission member 324 is carried out through gear meshing, and the transmission relationship is stable and reliable, so that the cleaning member 21 can swing stably between the retracted position and the swung-out position.

[0099] For example, when the cleaning member 21 is in the retracted position and the elastic member 321 and the first rotation axis are in the second positional relationship, the first drive motor 31 rotates in the forward direction. The first drive motor 31 drives the third transmission member 324 formed as a gear to rotate. The third transmission member 324 drives the second transmission member 323 formed as a half gear engaged therewith to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning member 21 remains in the retracted position;

[0100] Then, the first drive motor 31 continues to rotate in the forward direction. The first drive motor 31 continues to drive the third transmission member 324 formed as a gear to rotate. The third transmission member 324 continues to drive the second transmission member 323 formed as a half gear engaged therewith to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position, and further makes the positional relationship between the elastic member 321 and the first rotation axis gradually change from the first positional relationship to the third positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 line away from the center of the device body 1, so that the acting force of the elastic member 321 can provide a torque for the first transmission member 322 to drive the cleaning device to rotate in a direction away from the device body 1, so that the cleaning member 21 swings out from the retracted position to the swung-out position.

[0101] For example, when the cleaning member 21 is in the swung-out position and the elastic member 321 and the first rotation axis are in the third positional relationship, the first drive motor 31 rotates in the reverse direction. The first drive motor 31 drives the third transmission member 324 formed as a gear to rotate. The third transmission member 324 drives the second transmission member 323 formed as a half gear engaged therewith to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning member 21 remains in the swung-out position;

[0102] Next, the first drive motor 31 continues to rotate in the reverse direction. The first drive motor 31 continues to drive the third transmission member 324 formed as a gear to rotate. The third transmission member 324 continues to drive the second transmission member 323 formed as a half-gear that meshes with it to rotate. The second transmission member 323 drives a position change at one end of the elastic member 321 connected to the second transmission member 323. As a result, the positional relationship between the elastic member 321 and the first rotation axis gradually changes from the first positional relationship to the second positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 line closer to the center of the device body 1, so that the acting force of the elastic member 321 can provide the torque for the first transmission member 322 to drive the cleaning device to rotate in the direction close to the device body 1, so that the cleaning component 21 can be swung from the extended position to the retracted position.

[0103] By making the second transmission member 323 a half-gear, the half-gear can only mesh with the third transmission member 324 within a specific angular range. In this way, power transmission can only occur between the second transmission member 323 and the third transmission member 324 within a specific angular rotation range, so that the second transmission member 323 can further drive the cleaning component 21 to accurately stop or start in a specific positional relationship, that is, the cleaning component 21 can accurately swing between the retracted position and the extended position, improving the reliability and accuracy of the transmission system, and thus facilitating the stable operation of the cleaning device.

[0104] Reference Figure 9 , according to some alternative embodiments of the present invention, a first limiting protrusion 11 and a second limiting protrusion 12 for limiting the rotation angle of the second transmission member 323 are provided on the device body 1. The first limiting protrusion 11 and the second limiting protrusion 12 are respectively located on both sides in the circumferential direction of the second transmission member 323.

[0105] Among them, in the retracted position, the second transmission member 323 abuts against the first limiting protrusion 11; in the extended position, the second transmission member 323 abuts against the second limiting protrusion 12.

[0106] Optionally, the device body 1 includes a base, and the first limiting protrusion 11 and the second limiting protrusion 12 can be provided on the base. Optionally, the device body 1 can include a cover body 26 fixed to the base, and the cover body 26 covers at least part of the outside of the first drive assembly 3, and the first limiting protrusion 11 and the second limiting protrusion 12 can be provided inside the cover body 26.

[0107] By providing a first limiting protrusion 11 and a second limiting protrusion 12 on the device body 1 for limiting the rotation angle of the second transmission member 323, the first limiting protrusion 11 and the second limiting protrusion 12 provide a limiting effect on the second transmission member 323 by abutting against the second transmission member 323, and the first limiting protrusion 11 and the second limiting protrusion 12 can further improve the accuracy of the rotation angle of the second transmission member 323, so that the second transmission member 323 can accurately stop at a suitable position, so that the second transmission member 323 can drive the cleaning member 21 to accurately stop at the retracted position and the swung-out position.

[0108] According to some alternative embodiments of the present invention, the first transmission member 322 and the cleaning member 21 are connected by a swing arm 6. During the process that the first drive motor 31 stops operating and the swing arm 6 drives the cleaning member 21 to move from the swung-out position towards the retracted position under the action of an obstacle, the elastic member 321 is always in the third positional relationship. By making the elastic member 321 always in the third positional relationship during the process that the first drive motor 31 stops operating and the swing arm 6 drives the cleaning member 21 to move from the swung-out position towards the retracted position under the action of an obstacle, the elastic force of the elastic member 321 will not bypass the first rotation axis of the first transmission member 322, so that when the swing arm 6 gradually disengages from the obstacle, the cleaning member can swing back to the swung-out position under the restoring force of the elastic member 321.

[0109] According to some alternative embodiments of the present invention, the first transmission member 322 and the cleaning member 21 are connected by a swing arm 6. The device body 1 is provided with a third limiting protrusion 13 and a fourth limiting protrusion 14 for limiting the swing angle of the swing arm 6, and the third limiting protrusion 13 and the fourth limiting protrusion 14 are respectively located on opposite sides in the swing direction of the swing arm 6.

[0110] Wherein, when the cleaning member 21 is in the retracted position, the swing arm 6 abuts against the third limiting protrusion 13; when the cleaning member 21 is in the swung-out position, the swing arm 6 abuts against the fourth limiting protrusion 14.

[0111] By providing a third limiting protrusion 13 and a fourth limiting protrusion 14 on the device body 1 for limiting the swing angle of the swing arm 6, the third limiting protrusion 13 and the fourth limiting protrusion 14 form a limiting effect on the swing arm 6 by abutting against the swing arm 6, so as to ensure that the swing arm 6 drives the cleaning assembly to swing within a preset angle range, avoid the cleaning member 21 exceeding the predetermined swing range, so that the cleaning member 21 can be stably located at the retracted position and the swung-out position, and avoid the situation of excessive swing. By providing a swing arm 6 connected between the first transmission member 322 and the cleaning member, so that when the first transmission member 322 rotates a certain angle, the swing arm 6 can drive the cleaning member to swing within a range further away from the center of the device body 1, so that the cleaning member can have a larger cleaning range when in the swung-out position.

[0112] For example, when the cleaning component 21 is in the retracted position and the swing arm 6 abuts against the third limit projection 13, the elastic member 321 and the first rotation axis are in the second positional relationship, the second transmission member 323 abuts against the first limit projection 11, the first drive motor 31 rotates in the forward direction, the first drive motor 31 drives the third transmission member 324 formed as a gear to rotate, the third transmission member 324 drives the second transmission member 323 formed as a half-gear engaged therewith to rotate away from the first limit projection 11, the second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the third limit projection 13 abuts against the swing arm 6 to limit the rotation of the cleaning member towards the direction close to the center of the device body 1, and the cleaning component 21 is maintained in the retracted position;

[0113] Then, the first drive motor 31 continues to rotate in the forward direction, the first drive motor 31 continues to drive the third transmission member 324 formed as a gear to rotate, the third transmission member 324 continues to drive the second transmission member 323 formed as a half-gear engaged therewith to continue rotating away from the first limit projection 11, the second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, and further causes the positional relationship between the elastic member 321 and the first rotation axis to gradually change from the first positional relationship to the third positional relationship until the second transmission member 323 abuts against the second limit projection 12. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 away from the center of the device body 1, so that the acting force of the elastic member 321 can provide the torque for the first transmission member 322 to drive the cleaning device to rotate away from the device body 1, so that the cleaning component 21 is swung out from the retracted position to the swung-out position; when the second transmission member 323 abuts against the second limit projection 12, the swing arm 6 abuts against the fourth limit projection 14 to position the cleaning member in the swung-out position.

[0114] For example, when the cleaning component 21 is in the extended position, the swing arm 6 abuts against the fourth limiting projection 14, the elastic member 321 and the first rotation axis are in the third positional relationship, the second transmission member 323 abuts against the second limiting projection 12, and the first drive motor 31 rotates in the reverse direction. The first drive motor 31 drives the third transmission member 324 formed as a gear to rotate. The third transmission member 324 drives the second transmission member 323 formed as a half-gear meshing therewith to rotate away from the second limiting projection 12. The second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the fourth limiting projection 14 abuts against the swing arm 6 to limit the rotation of the cleaning member away from the center of the device body 1, and the cleaning component 21 is maintained in the extended position;

[0115] Next, the first drive motor 31 continues to rotate in the reverse direction. The first drive motor 31 continues to drive the third transmission member 324 formed as a gear to rotate. The third transmission member 324 continues to drive the second transmission member 323 formed as a half-gear meshing therewith to continue rotating away from the second limiting projection 12. The second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, thereby causing the positional relationship between the elastic member 321 and the first rotation axis to gradually change from the first positional relationship to the second positional relationship until the second transmission member 323 abuts against the first limiting projection 11. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 line closer to the center of the device body 1, so that the acting force of the elastic member 321 can provide the torque for the first transmission member 322 to drive the cleaning device to rotate towards the direction close to the device body 1, so that the cleaning component 21 is swung from the extended position to the retracted position; when the second transmission member 323 abuts against the first limiting projection 11, the swing arm 6 abuts against the third limiting projection 13, and the cleaning component 21 is located in the retracted position.

[0116] Reference Figures 8 - 9 Referring to

[0117] The first transmission member 322 is sleeved on the transmission shaft 24 loosely and is connected to the cleaning member 21 through the swing arm 6. Optionally, the first transmission member 322 is detachably connected to the swing arm 6. For example, the first transmission member 322 is connected to the swing arm 6 through a fastener.

[0118] Optionally, the first transmission member 322 is connected to one end of the swing arm 6 along the length direction, and the cleaning member 21 is located at the other end of the swing arm 6 along the length direction.

[0119] Herein, the first transmission member 322 being sleeved on the transmission shaft 24 loosely means that there is no transmission relationship between the first transmission member 322 and the transmission shaft 24. During the process of the cleaning member 21 swinging between the retracted position and the swung-out position, the first transmission member 322 can rotate relative to the transmission shaft 24. By making the first transmission member 322 sleeved on the transmission shaft 24 loosely and connected to the cleaning member 21 through the swing arm 6, the first transmission member 322 drives the swing arm 6 and the cleaning member 21 to swing around the rotating shaft between the retracted position and the swung-out position.

[0120] Reference Figures 8 - 9 Referring to, according to some optional embodiments of the present utility model, the swing arm 6 has a first accommodation cavity 61 inside, the second transmission mechanism 25 is accommodated in the first accommodation cavity 61, the swing arm 6 can form a support and protection effect on the second transmission structure, and an avoidance hole 62 is formed on the swing arm 6. The lower end of the transmission shaft 24 passes through the avoidance hole 62 and extends into the first accommodation cavity 61. During the process of the swing arm 6 driving the cleaning assembly to swing between the retracted position and the swung-out position, the second transmission mechanism 25 can rotate around the axis of the transmission shaft 24. Such a setting makes the swing arm 6 drive the second transmission mechanism 25 located in the first accommodation cavity 61 to move together during the process of the first transmission member 322 and the swing arm 6 driving the cleaning member 21 to swing between the retracted position and the swung-out position, so that when in the swung-out position, the second driving assembly can still stably drive the cleaning assembly to rotate around its own axis to complete the cleaning of the working surface.

[0121] Reference Figures 8 - 9 Referring to, according to some optional embodiments of the present utility model, a accommodation space 7 is defined inside the first transmission member 322, at least part of the transmission shaft 24 and at least part of the first transmission mechanism 23 are located in the accommodation space 7, and one end of the swing arm 6 is connected to the first transmission member 322 and is located in the accommodation space 7. Herein, at least part of the transmission shaft 24 and at least part of the first transmission mechanism 23 being located in the accommodation space 7 can include the following several situations: for example, part of the transmission shaft 24 and part of the first transmission mechanism 23 are located in the accommodation space 7; for another example, the transmission shaft 24 and the first transmission mechanism 23 are all located in the accommodation space 7. The structural layout of the first transmission member 322, the transmission shaft 24, the first transmission structure, the swing arm 6, etc. is reasonable and the structure is compact.

[0122] ReferenceFigures 8 - 9 According to some alternative embodiments of the present utility model, the first transmission mechanism 23 includes a driving gear 231, a first gear transmission mechanism 232, and a first transmission gear 233. The driving gear 231 is fixed to the motor shaft of the second driving motor 22, the first transmission gear 233 is fixed to the transmission shaft 24, and the first gear transmission mechanism 232 is drivably connected between the driving gear 231 and the first transmission gear 233.

[0123] The second transmission mechanism 25 includes a driven gear 251, a second gear transmission mechanism 252, and a second transmission gear 253. The driven gear 251 is fixed to the cleaning component 21, the second transmission gear 253 is fixed to the transmission shaft 24 and the first transmission gear 233 is arranged at an axial interval along the transmission shaft 24, and the second gear transmission mechanism 252 is drivably connected between the driven gear 251 and the second transmission gear 253. The other end of the swing arm 6 is connected to the driven gear 251.

[0124] During the process of the swing arm 6 driving the cleaning assembly to swing between the retracted position and the extended position, the second transmission gear 253 and the transmission shaft 24 are fixed, and the swing arm 6 drives the second gear transmission mechanism 252 and the driven gear 251 to rotate relative to the second transmission gear 253.

[0125] For example, during the process of the second driving assembly driving the cleaning assembly to rotate around its own rotation axis to clean the working surface, the transmission relationship is as follows: the second driving motor 22 drives the driving gear 231 to rotate, the driving gear 231 drives the first gear transmission structure to rotate and then drives the first transmission gear 233 to rotate, the first transmission gear 233 drives the transmission shaft 24 to rotate, the transmission shaft 24 drives the second transmission gear 253 coaxially arranged with the first transmission gear 233 to rotate, and the second transmission gear 253 drives the second gear transmission mechanism 252 to rotate and then drives the driven gear 251 to rotate, so that the driven gear 251 can drive the cleaning component 21 fixed thereto to rotate to clean the working surface. When the cleaning component 21 is in the retracted position and the extended position, the second driving assembly can drive the cleaning component 21 to rotate through the above transmission relationship to complete the cleaning operation.

[0126] For example, during the process of the first cleaning assembly driving the cleaning component 21 to swing from the retracted position towards the extended position, the transmission relationship is as follows: the first driving motor 31 drives the third transmission member 324 and the second transmission member 323 to rotate, and the second transmission member 323 drives one end of the elastic member 321 connected thereto to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis first changes from the second positional relationship to the first positional relationship, and then changes from the first positional relationship to the third positional relationship;

[0127] During the process of changing from the first positional relationship to the third positional relationship, the acting force of the elastic member 321 can provide a tangential torque for the first transmission member 322, so that the first transmission member 322 drives the swing arm 6 to rotate around the transmission shaft 24 in a direction away from the center of the device body 1, and further enables the swing arm 6 to drive the cleaning assembly to swing in a direction away from the center of the device body 1 until it reaches the extended position. During the swinging process of the swing arm 6, the second transmission gear 253 and the transmission shaft 24 are fixed, and the swing arm 6 drives the second gear transmission mechanism 252 and the driven gear 251 to rotate relative to the second transmission gear 253.

[0128] The arrangement of the second transmission mechanism 25 and the swing arm 6 makes the structure of the cleaning device compact and the transmission relationship reasonably set. The cleaning component 21 can not only rotate but also swing, avoiding the relevant structures of the second drive assembly from interfering with the movement of the swing arm 6 and the movement of the cleaning assembly between the retracted position and the extended position.

[0129] According to some embodiments of the present invention, the first cleaning module 2 is a side brush module, and the first cleaning module 2 is adjacent to the outer peripheral edge of the device body 1. By making the cleaning module adjacent to the outer peripheral edge of the device body, it is beneficial to expand the cleaning range of the first cleaning module 2; and the setting of the side brush module is beneficial to improving the cleaning degree of the cleaning device at positions such as corners and wall roots.

[0130] According to some alternative embodiments of the present invention, there are multiple first cleaning modules 2, and the multiple first cleaning modules 2 are arranged at intervals along the circumferential direction of the device body 1. By making there be multiple first cleaning modules 2 and arranging the multiple first cleaning modules 2 at intervals along the circumferential direction of the device body, it is beneficial to increase the cleaning area of the first cleaning module 2, thereby further improving the cleaning effect of the cleaning device.

[0131] According to some alternative embodiments of the present invention, it further includes a second cleaning module installed on the device body 1. The second cleaning module is the main cleaning module, and the second cleaning module is arranged adjacent to the center of the device body 1. For example, the second cleaning module is a roller brush assembly. By arranging the second cleaning module adjacent to the center of the device body 1, the second cleaning module as the main cleaning module is beneficial to the cleaning device to effectively clean the working surface.

[0132] According to some alternative embodiments of the present invention, the first cleaning module 2 and the second cleaning module are arranged at intervals in the front-rear direction. By making the first cleaning module 2 and the second cleaning module arranged at intervals in the front-rear direction, it can avoid interference between the first cleaning module 2 and the second cleaning module when cleaning the working surface.

[0133] According to the cleaning system of the second aspect of the present utility model, the cleaning system includes: the above-mentioned cleaning device and the cleaning base station. The cleaning device is adapted to cooperate with the cleaning base station. The cleaning base station is used to clean the cleaning device and can also be used to charge the cleaning device.

[0134] According to the cleaning system of the embodiments of the present utility model, by providing the above-mentioned cleaning device, the cleaning device is provided with a first driving component 3 including a first driving motor 31 and a transmission component, and the transmission component includes an elastic member 321. In this way, the first driving component 3 can drive the cleaning component 21 to swing between the retracted position and the extended position according to the working needs of the cleaning device. When the cleaning component 21 swings to the extended position, it can expand the cleaning range towards the outside of the cleaning device, so as to facilitate the cleaning component 21 to clean areas such as the corners that the device body 1 cannot reach, thereby reducing or avoiding cleaning dead corners during the cleaning process of the cleaning device. In addition, the setting of the elastic member 321 also enables when the cleaning component 21 is in the extended position, if the cleaning component 21 encounters an obstacle collision, it can swing towards the retracted position by compressing the elastic member 321, so as to avoid damage to the cleaning device caused by the collision or avoid the cleaning device from malfunctioning due to the obstruction of the obstacle.

[0138] The first driving assembly 3 includes a first driving motor 31 and a transmission assembly.

[0139] The second transmission member 323 is a semi-gear, and the third transmission member 324 is a gear. The third transmission member 324 is fixed to the motor shaft of the first driving motor 31 and meshes with the second transmission member 323.

[0140] The first transmission member 322 and the second transmission member 323 are coaxially arranged and are axially spaced apart along the axis of the first transmission member 322. In the axial direction of the first transmission member 322, the elastic member 321 is located between the first transmission member 322 and the second transmission member 323. The elastic member 321 is a tension spring. A first mounting post 41 is provided at the radially outer end of the first transmission member 322.

The first hook portion 42 is sleeved on the first mounting post 41, and the second hook portion 52 is sleeved on the second mounting post 51.

[0141] The device body 1 is provided with a first limiting protrusion 11 and a second limiting protrusion 12 for limiting the rotation angle of the second transmission member 323. The first limiting protrusion 11 and the second limiting protrusion 12 are respectively located on both sides in the circumferential direction of the second transmission member 323. Among them, in the retracted position, the second transmission member 323 abuts against the first limiting protrusion 11; in the deployed position, the second transmission member 323 abuts against the second limiting protrusion 12.

[0142] The first transmission member 322 is connected to the cleaning member 21 through a swing arm 6. A third limit projection 13 and a fourth limit projection 14 for limiting the swing angle of the swing arm 6 are provided on the device body 1. The third limit projection 13 and the fourth limit projection 14 are respectively located on opposite sides in the swing direction of the swing arm 6. Among them, when the cleaning member 21 is in the retracted position, the swing arm 6 abuts against the third limit projection 13; when the cleaning member 21 is in the extended position, the swing arm 6 abuts against the fourth limit projection 14.

[0143] The first cleaning module 2 includes a second drive assembly for driving the cleaning member 21 to rotate about its own central axis. The second drive assembly includes a second drive motor 22, a first transmission mechanism 23, a transmission shaft 24, and a second transmission mechanism 25. The second drive motor 22 is installed on the device body 1. The first transmission mechanism 23 is drivably connected between the motor shaft of the second drive motor 22 and the transmission shaft 24. The second transmission mechanism 25 is drivably connected between the transmission shaft 24 and the cleaning member 21. The first transmission member 322 is sleeved on the transmission shaft 24 and is connected to the cleaning member 21 through the swing arm 6.

[0144] The swing arm 6 has a first accommodation cavity 61 inside. The second transmission mechanism 25 is accommodated in the first accommodation cavity 61. An avoidance hole 62 is formed on the swing arm 6. The lower end of the transmission shaft 24 passes through the avoidance hole 62 and extends into the first accommodation cavity 61.

[0145] The first transmission mechanism 23 includes a driving gear 231, a first gear transmission mechanism 232, and a first transmission gear 233. The driving gear 231 is fixed to the motor shaft of the second drive motor 22. The first transmission gear 233 is fixed to the transmission shaft 24.

[0146] The rotation axis of the first transmission member 322 is the first rotation axis. There are a first positional relationship, a second positional relationship, and a third positional relationship between the elastic member 321 and the first rotation axis. Among them, in the first positional relationship, the elastic force of the elastic member 321 passes through the first rotation axis; in the second positional relationship, the elastic force of the elastic member 321 is spaced apart from the first rotation axis and is located on the side closer to the center of the device body 1 of the first rotation axis; in the third positional relationship, the elastic force of the elastic member 321 is spaced apart from the first rotation axis and is located on the side away from the center of the device body 1 of the first rotation axis. When the cleaning member 21 is in the retracted position, the elastic member 321 is in the first positional relationship or the second positional relationship; when the cleaning member 21 is in the extended position, the elastic member 321 is in the third positional relationship.

[0147] During the process that the first drive motor 31 stops and the swing arm 6 drives the cleaning member 21 to move from the extended position towards the retracted position under the action of an obstacle, the elastic member 321 is always in the third positional relationship.

[0148] Next, refer to Figures 14 - 15 to describe some other embodiments of the present invention.

[0149] Refer to Figures 14 - 15 , in this embodiment, the first drive assembly 3 includes a first drive motor 31, a first transmission member 322, a second transmission member 323, and an elastic member 321. The second transmission member 323 is a swing rod. One end of the swing rod along the length direction is sleeved on the motor shaft of the first drive motor 31, and a second mounting post 51 is formed at the other end of the swing rod along the length direction. The second hook portion 52 of the elastic member 321 is connected to the second mounting post 51. The rotation axes of the first transmission member 322 and the second transmission member 323 are not the same.

[0150] A first mounting post 41 is formed on the first transmission member 322, and the first hook portion 42 of the elastic member 321 is connected to the first mounting post 41, so that the elastic member 321 is connected between the first transmission member 322 and the second transmission member 323.

[0151] For example, when the cleaning member 21 is in the retracted position and the elastic member 321 and the first rotation axis are in the second positional relationship, the first drive motor 31 rotates in the forward direction. The first drive motor 31 drives the second transmission member 323 to rotate, and the second transmission member 323 drives the end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning member 21 remains in the retracted position;

[0152] Next, the first driving motor 31 continues to rotate in the forward direction. The first driving motor 31 continues to drive the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position. As a result, the positional relationship between the elastic member 321 and the first rotation axis gradually changes from the first positional relationship to the third positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 away from the center of the device body 1, so that the acting force of the elastic member 321 can provide a torque for the first transmission member 322 to drive the cleaning device to rotate away from the device body 1, so that the cleaning component 21 can be swung out from the retracted position to the swung-out position.

[0153] For example, when the cleaning component 21 is in the swung-out position and the elastic member 321 and the first rotation axis are in the third positional relationship, the first driving motor 31 rotates in the reverse direction. The first driving motor 31 drives the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position, so that the positional relationship between the elastic member 321 and the first rotation axis gradually changes to the first positional relationship. During this process, the cleaning component 21 remains in the swung-out position;

[0154] Next, the first driving motor 31 continues to rotate in the reverse direction. The first driving motor 31 continues to drive the second transmission member 323 to rotate. The second transmission member 323 drives one end of the elastic member 321 connected to the second transmission member 323 to change its position. As a result, the positional relationship between the elastic member 321 and the first rotation axis gradually changes from the first positional relationship to the second positional relationship. During this process, the elastic member 321 is spaced apart from the first rotation axis and is located on the side of the first transmission shaft 24 close to the center of the device body 1, so that the acting force of the elastic member 321 can provide a torque for the first transmission member 322 to drive the cleaning device to rotate towards the device body 1, so that the cleaning component 21 can be swung out from the swung-out position to the retracted position.
