Description

Technical Field

[0001] This invention belongs to the field of cleaning robot technology, and particularly relates to a brush assembly and a cleaning robot. Background Technology

[0002] With the continuous development of the Internet and artificial intelligence technologies, more and more smart home devices have emerged and entered our daily lives. Among them, cleaning robots, as robots that can truly free up our hands, have been favored by more and more users due to their good application prospects and broad market demand.

[0003] Most current cleaning robots use brushes to clean the floor. When the robot needs to clean, it lowers the brush to the surface to be cleaned. When cleaning is not needed, the brush is raised to avoid contact with the floor, thus extending the cleaning time.

[0004] The lifespan of the disc and its function of protecting the ground.

[0005] However, because the brush needs to rub against the floor for a long time during use, and when the ground is uneven or there are obstacles, it is easy to create a blocking force on the brush. This causes the brush to move up and down slightly or shake under the action of external force, resulting in poor cleaning stability and the problem of incomplete cleaning. Summary of the Invention

[0006] The present invention provides a brush assembly and a cleaning robot, which aims to solve at least one of the problems existing in the prior art.

[0007] This invention is implemented by providing a disk brushing component, comprising:

[0009] A lifting arm, one end of which is movably connected to the power output shaft of the rotary lifting mechanism, is used to move up and down under the drive of the rotary lifting mechanism. The lifting arm is provided with a locking groove.

[0010] A rotating brush disk that is movably connected to the other end of the lifting arm and rotates under the drive of the rotating lifting mechanism;

[0011] as well as

[0012] A locking mechanism for engaging with the locking groove to fix the rotating brush in the working position;

[0013] When the lifting arm descends to the first preset position, the locking mechanism engages with the locking groove. When the lifting arm rises to the second preset position, the locking mechanism automatically slides out of the locking groove.

[0014] In one embodiment, the disk brushing assembly includes:

[0015] A gearbox is disposed between the rotary lifting mechanism and the lifting swing arm to adjust the rotational speed of the rotary brush. The bottom of the gearbox is provided with a mounting groove, and the locking mechanism is installed in the mounting groove.

[0016] In one embodiment, the locking mechanism includes:

[0017] A locking structure disposed in the mounting groove and engaged with the locking groove;

[0018] An elastic structure movably connected to the end of the locking structure away from the lifting arm; and

[0019] The upper cover structure is detachably assembled with the mounting slot to install the locking structure and the elastic structure in the mounting slot.

[0020] In one embodiment, the locking structure includes:

[0021] Support structure;

[0022] A locking pin is fixedly assembled with the first end face of the support structure and engages with the locking groove, and the free end of the locking pin is provided with a first inclined surface.

[0023] A mounting rod fixedly assembled to the second end face of the support structure, the elastic structure being sleeved on the mounting rod; and

[0024] A fixed structure that is fixedly assembled to the second end of the support structure.

[0025] In one embodiment, the locking groove has a second inclined surface on the side near the rotating brush disk.

[0026] In one embodiment, the locking mechanism includes:

[0027] The locking mechanism body mounted on the base of the cleaning robot; and

[0028] An elastic locking structure disposed on the locking mechanism body for engaging with the locking groove.

[0029] In one embodiment, the resilient locking structure includes:

[0030] One end is disposed on the locking mechanism body, and the remaining positions form a U-shaped groove penetrating the upper and lower surfaces of the locking mechanism body.

[0031] An elastic locking pin structure disposed on the spring sheet structure for engaging with the locking groove.

[0032] In one embodiment, the rotary lifting mechanism includes:

[0033] A rotary drive component, wherein the power output shaft of the rotary drive component is movably connected to a first transmission mechanism rotatably disposed within the gearbox via a clutch;

[0034] A lifting drive component installed in the gearbox to drive the lifting arm to move up and down.

[0035] In one embodiment, the rotating brush disk includes a first rotating brush disk and a second rotating brush disk, and the rotating drive is connected to the first rotating brush disk and the second rotating brush disk to drive the first rotating brush disk and the second rotating brush disk to rotate in opposite directions at the same speed.

[0036] This application also provides a cleaning robot, including:

[0037] A cleaning robot body, on which a base is provided;

[0038] The brush assembly, as described above, is mounted on the base.

[0039] This invention provides a brush assembly and a cleaning robot. The brush assembly includes: a rotary lifting mechanism; a lifting arm with one end movably connected to the power output shaft of the rotary lifting mechanism for vertical movement under the drive of the rotary lifting mechanism, the lifting arm having a locking groove; a rotary brush disk movably connected to the other end of the lifting arm for rotation under the drive of the rotary lifting mechanism; and a locking mechanism for engaging with the locking groove to fix the rotary brush disk in a working position. When the lifting arm descends to a first preset position, the locking mechanism engages with the locking groove; when the lifting arm rises to a second preset position, the locking mechanism automatically slides out of the locking groove. In this embodiment, a locking groove is provided on the lifting arm. When the lifting arm descends to the position of the cleaning surface, the locking mechanism can engage with the locking groove to lock the lifting arm. The rotating brush can then rotate to perform cleaning. After cleaning, the lifting arm rises under the drive of the rotating lifting mechanism. At this time, the locking mechanism gradually slides out of the locking groove, unlocking the lifting arm. This automatic locking and unlocking during the lifting arm's ascent and descent is achieved, simplifying operation and preventing slight up-and-down wobbling or movement of the rotating brush during operation, thus ensuring cleaning stability and improving cleaning effectiveness.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] Example 1

[0057] See Figures 1-7 This application provides a brush assembly, including: a rotary lifting mechanism 1; a lifting arm 2, one end of which is movably connected to the power output shaft of the rotary lifting mechanism 1 for vertical movement under the drive of the rotary lifting mechanism 1, the lifting arm 2 having a locking groove 21; a rotary brush 3, the other end of which is movably connected to the lifting arm 2 for rotation under the drive of the rotary lifting mechanism 1; and a locking mechanism 4 for engaging with the locking groove 21 to fix the rotary brush 3 in a working position; when the lifting arm 2 descends to a first preset position, the locking mechanism 4 engages with the locking groove 21, and when the lifting arm 2 rises to a second preset position, the locking mechanism 4 automatically slides out of the locking groove 21.

[0058] The first preset position can be the working position, such as the ground, and the second preset position can be the storage position for the rotating brush 3. The height of the first preset position is lower than the height of the second preset position. This allows the cleaning robot to be locked in the working position during operation, improving the cleaning effect.

[0059] In this embodiment of the application, the brush assembly further includes: a gearbox 5 disposed between the rotary lifting mechanism 1 and the lifting swing arm 2 to adjust the rotational speed of the rotary brush 3. Specifically, the gearbox 5 is provided with a first transmission mechanism 51, and the power output shaft of the rotary lifting mechanism 1 can be connected to the first transmission mechanism 51 for transmission, and the rotational speed transmitted by the rotary lifting mechanism 1 can be adjusted through the first transmission mechanism 51.

[0060] See Figures 1-3In this embodiment, the rotary lifting mechanism 1 may include a rotary drive 11 and a lifting drive 12. The power output shaft of the rotary drive 11 is movably connected to a first transmission mechanism 51 rotatably disposed within a gearbox 5 via a clutch (not shown in the figure). The first transmission mechanism 51 drives the rotary brush 3 to rotate. The lifting drive 12 may be disposed in the gearbox 5 and movably connected to a second transmission mechanism 52 rotatably disposed within the gearbox. The second transmission mechanism 52 drives the lifting arm 2 to move up and down. When the brush is working, the lifting drive 12 first drives the lifting arm 2 to descend to a first preset position, such as the ground. At this time, the lifting arm 2 is at 0 degrees. The rotary drive 11 is activated to drive the rotary brush 3 to rotate and clean the ground. After cleaning is completed, the lifting drive 12 can drive the lifting arm 2 to rise again to a second preset position, i.e., the original storage position, so as to store the brush.

[0061] Both the rotary drive component 11 and the lifting drive component 12 can be drive motors.

[0062] Both the first transmission mechanism 51 and the second transmission mechanism 52 can be gear sets, which may include multiple gears, and transmission is achieved through the meshing of multiple gears.

[0063] In one embodiment of this application, the rotating brush disk 3 may include two rotating brush disks arranged opposite each other, specifically including a first rotating brush disk and a second rotating brush disk. The rotating drive member 11 is respectively connected to the first rotating brush disk and the second rotating brush disk to drive the first rotating brush disk and the second rotating brush disk to rotate in opposite directions at the same speed. Specifically, the two end power output shafts of the rotating drive member 11 are respectively connected to the first rotating brush disk and the second rotating brush disk through a gearbox 5, and can simultaneously drive the first rotating brush disk and the second rotating brush disk to rotate in opposite directions at the same speed.

[0064] See Figures 1-3 In this embodiment, the lifting arm 2 may be provided with a mounting slot. One end of the arm is movably connected to the rotating lifting mechanism 1, and the other end is movably connected to the rotating brush disk 3. Driven by the rotating lifting mechanism 1, the rotating shaft 6 of the rotating brush disk 3 is rotated. The rotating shaft 6 and the rotating brush disk 3 can be connected by a rotating bushing and rotate from 0 degrees to 180 degrees under the drive of the rotating shaft 6. The maximum rotation angle is 180 degrees. When the rotation reaches 180 degrees, the first transmission mechanism 51 in the gearbox 5 can rotate the rotating shaft in the opposite direction. This reciprocating motion allows for cleaning along the edge of an object while also cleaning the ground in the forward direction. It enables two mopping states: mopping the center of the machine and mopping along the edge of an object.

[0065] See Figure 3 In this embodiment, the gearbox 5 has a mounting groove 53 at its bottom, and the locking mechanism 4 is installed in the mounting groove 53. It can be assembled using fasteners such as bolts (not shown in the figure).

[0066] See Figures 5-7 In this embodiment of the application, the locking mechanism 4 includes: a locking structure 41 disposed in the mounting groove 53 and engaged with the locking groove 21; an elastic structure 42 movably connected to one end of the locking structure 41 away from the lifting swing arm 2; and an upper cover structure 43 detachably assembled with the mounting groove 52 to install the locking structure 41 and the elastic structure 42 in the mounting groove 52.

[0067] When the rotating brush 3 descends to the first preset position, such as the ground, driven by the lifting arm 2, during the descent, since the locking mechanism 4 remains stationary and the elastic structure 42 is in a compressed state, when the lifting arm 2 descends to the position where the locking structure 41 overlaps with the locking groove 21, the elastic structure 42 undergoes elastic deformation and provides a force to the locking structure 41 to push the locking structure 41 into the locking groove 21. The locking structure 41 engages with the locking groove 21, thereby locking the lifting arm 2. At this time, the rotating shaft is at 0 degrees, and the rotating brush 3 enters the working state. When the rotating brush 3 finishes its work, it rises to its original position under the drive of the lifting arm 2. During the rise, since the position of the locking mechanism 4 is fixed, the position of the locking groove 21 moves upward. The bottom of the locking groove 21 will apply a pushing force to the locking structure 41, causing the elastic structure 42 to be compressed again. The locking structure 41 gradually slides out of the locking groove 21, thereby unlocking the lifting arm 2.

[0068] The upper cover structure 43 is used to enclose the locking structure 41 and the elastic structure 42 in the mounting groove 52, and can be fixed and assembled by means of bolts or other detachable methods.

[0069] The elastic structure 42 can be a spring, sheet metal, or other elastic structure.

[0070] See Figure 7In this embodiment, the locking structure 41 includes: a support structure 411; a locking pin 412 fixedly assembled with the first end face of the support structure 411 and engaging with the locking groove 21, wherein the free end of the locking pin 412 is provided with a first inclined surface 413; an mounting rod 414 fixedly assembled with the second end face of the support structure 411, wherein the elastic structure 42 is sleeved on the mounting rod 414; and a fixing structure 415 fixedly assembled with the second end of the support structure 411. The elastic structure 42 is arranged in the opposite direction to the locking pin 412, so that the elastic structure 42 can provide a pushing force to the locking pin 412, causing the locking pin 412 to slide into the locking groove 21, and the locking pin 412 can also provide a force to the elastic structure 42 to compress the elastic structure 42, thereby moving the locking pin 412 out of the locking groove 21.

[0071] The locking structure 41 can be a one-piece molded structure, and it can be made of metal.

[0072] See Figure 8 In this embodiment, a second inclined surface 211 is provided on the side of the locking groove 21 near the rotating brush disk 3. The inclination angle of the second inclined surface 211 matches that of the first inclined surface 413. That is, when the first inclined surface 413 contacts the second inclined surface 211, they fit together. When the rotating brush disk 3 rises, the second inclined surface 211 can provide a pushing force to the first inclined surface 413. Due to the inclination setting, the locking pin 412 can be smoothly moved out of the locking groove 21.

[0073] In this embodiment, the locking groove 21 can be arranged along the length of the lifting arm 2, and the whole can be rectangular so that the locking structure 41 can slide up and down in the locking groove 21.

[0074] In this embodiment, a locking groove is provided on the lifting arm. When the lifting arm descends to the position of the cleaning surface, the locking mechanism can engage with the locking groove to lock the lifting arm. The rotating brush can then rotate to perform cleaning. After cleaning, the lifting arm rises under the drive of the rotating lifting mechanism. At this time, the locking mechanism gradually slides out of the locking groove, unlocking the lifting arm. This automatic locking and unlocking during the lifting arm's ascent and descent is achieved, simplifying operation and preventing slight up-and-down wobbling or movement of the rotating brush during operation, thus ensuring cleaning stability and improving cleaning effectiveness.

[0075] Example 2

[0076] See Figure 9-11This application provides a brush assembly, including: a rotary lifting mechanism 1; a lifting arm 2, one end of which is movably connected to the power output shaft of the rotary lifting mechanism 1 for vertical movement under the drive of the rotary lifting mechanism 1, the lifting arm 2 having a locking groove 21; a rotary brush 3, the other end of which is movably connected to the lifting arm 2 for rotation under the drive of the rotary lifting mechanism 1; and a locking mechanism 4 for engaging with the locking groove 21 to fix the rotary brush 3 in a working position; when the lifting arm 2 descends to a first preset position, the locking mechanism 4 engages with the locking groove 21, and when the lifting arm 2 rises to a second preset position, the locking mechanism 4 automatically slides out of the locking groove 21. It is similar to Embodiment 1, except that the locking mechanism 4 includes: a locking mechanism body 44 mounted on a 7; and an elastic locking structure 45 disposed on the locking mechanism body 44 for engaging with the locking groove 21.

[0077] See Figure 5 , Figure 6 When the rotating brush 3 descends to the first preset position, such as the ground, driven by the lifting arm 2, the position of the locking mechanism body 44 remains fixed during the descent. The lifting arm 2 provides a thrust to the elastic locking structure 45, causing the elastic locking structure 45 to be in a deformed state. Therefore, when the lifting arm 2 descends to the position where the locking groove 21 coincides with the elastic locking structure 45, the elastic locking structure 45 moves towards the position of the lifting arm 2 under the action of its own elastic deformation, so that the elastic locking structure 45 enters the locking groove 21. The elastic locking structure 45 engages with the locking groove 21, thereby locking the lifting arm 2. At this time, the rotating shaft is at 0 degrees, and the rotating brush 3 enters the working state. When the rotating brush 3 finishes its work, it rises to its original position under the drive of the lifting arm 2. During the rise, since the position of the locking mechanism 4 is fixed, the position of the locking groove 21 moves upward. The bottom of the locking groove 21 will exert a pushing force on the elastic locking structure 45, causing the elastic locking structure 45 to deform and slide out of the locking groove 21, thereby unlocking the lifting arm 2.

[0078] The locking groove 21 of the lifting arm 2 can be an annular groove, specifically encircling the periphery of the lifting arm. Alternatively, the locking groove 21 can also be rectangular or other shapes.

[0079] See Figure 11In this embodiment, the elastic locking structure 45 includes: a spring sheet structure 451 with one end disposed on the locking mechanism body 44, and the remaining positions forming a U-shaped groove 46 penetrating the upper and lower surfaces of the locking mechanism body 44; and an elastic locking pin structure 452 disposed on the spring sheet structure 451 for engaging with the locking groove 21. Because it is disposed in the U-shaped groove 46, one end of the spring sheet structure 451 is located at the open end of the U-shaped groove 46, and the remaining positions are free ends. Therefore, the spring sheet structure 451 can be engaged with the U-shaped groove along the upper surface of the locking mechanism body 44 by external force or the force generated by its own elastic deformation. The lifting arm 2 moves downwards, which in turn moves the elastic locking pin structure 452. Therefore, during the descent of the lifting arm 2, it provides a force to the elastic locking pin 452 that moves away from the lifting arm 2. When the lifting arm 2 descends to the position where the elastic locking pin 452 corresponds to the locking groove 21, the spring plate structure 451 provides a pushing force to the elastic locking pin 452 facing the locking groove 21 under the action of elastic deformation, so that the elastic locking pin 452 slides into the locking groove 21 and locks. When the lifting arm 2 rises, it provides a pushing force to the elastic locking pin 452, so that the elastic locking pin 452 moves away from the lifting arm 2 and disengages from the locking groove 21, thereby unlocking.

[0080] In this embodiment, the locking mechanism 4 may be an elastic element, such as a rubber element, which may be an integrally molded structure.

[0081] In this embodiment of the application, the base 7 may be provided with a mounting position, the locking mechanism 4 may be movably embedded in the mounting position, and the locking mechanism 4 may be replaced in time when it is damaged.

[0082] In this embodiment, a locking groove is provided on the lifting arm. When the lifting arm descends to the position of the cleaning surface, the locking mechanism can engage with the locking groove to lock the lifting arm. The rotating brush can then rotate to perform cleaning. After cleaning, the lifting arm rises under the drive of the rotating lifting mechanism. At this time, the locking mechanism gradually slides out of the locking groove, unlocking the lifting arm. This automatic locking and unlocking during the lifting arm's ascent and descent is achieved, simplifying operation and preventing slight up-and-down wobbling or movement of the rotating brush during operation, thus ensuring cleaning stability and improving cleaning effectiveness.

[0083] Example 3

[0084] See Figure 9 , Figure 10 This application also provides a cleaning robot, including a cleaning robot body (not shown in the figure), a base 7 disposed on the cleaning robot body; and a brush assembly disposed on the base 7 as described in Embodiments 1 and 2 above.

[0085] In this embodiment, the lifting arm 2 may include two units, and the rotating brush 3 may also include two units. Both lifting arms 2 can be locked using the locking mechanism 4 provided in Embodiment 1, or both can be locked using the locking mechanism 4 provided in Embodiment 2. Alternatively, both the locking mechanisms 4 provided in Embodiment 1 and Embodiment 2 can be used for locking. Regardless of whether the locking mechanism 4 provided in Embodiment 1 or Embodiment 2 is used, automatic locking and unlocking can be achieved by raising or lowering the height of the lifting arm 2. The structure is simple, and it makes the cleaning robot more stable during operation, effectively avoiding problems with poor cleaning results.

[0086] In this embodiment, a locking groove is provided on the lifting arm. When the lifting arm descends to the position of the cleaning surface, the locking mechanism can engage with the locking groove to lock the lifting arm. The rotating brush can then rotate to perform cleaning. After cleaning, the lifting arm rises under the drive of the rotating lifting mechanism. At this time, the locking mechanism gradually slides out of the locking groove, unlocking the lifting arm. This automatic locking and unlocking during the lifting arm's ascent and descent is achieved, simplifying operation and preventing slight up-and-down wobbling or movement of the rotating brush during operation, thus ensuring cleaning stability and improving cleaning effectiveness.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
