[0059] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0060] Reference Figures 1 to 7The embodiment provides a cleaning device 10, which comprises a cleaning assembly 100, a rotating piece 200 and a lifting transmission piece 300. The rotating piece 200 is arranged to rotate around a first axis R, and the rotating piece 200 is provided with a first transmission part 210; the lifting transmission piece 300 is provided with a second transmission part 310 and a third transmission part 320, the second transmission part 310 is in abutment with the first transmission part 210 and is arranged to rotate around a central axis of the second transmission part 310 relative to the first transmission part 210; and the third transmission part 320 is connected with the second transmission part 310 and the cleaning assembly 100 respectively. The third transmission part 320 is arranged to form a preset included angle K with a turning axis S and is radially limited by the cleaning assembly 100; the first transmission part 210 is used to drive the second transmission part 310 to rotate around the first axis R, so that the third transmission part 320 rotates around the first axis R following the second transmission part 310, and drives the cleaning assembly 100 to rotate around the turning axis S under the action of the preset included angle K.

[0061] The first axis R can be an axis passing through the center of the rotating piece 200, the rotating piece 200 is arranged to rotate around the first axis R, and the driving force source can be a driving motor, but can also be other output driving devices, such as a heat engine, a hydraulic mechanism and the like.

[0062] When the rotating piece 200 rotates around the first axis R, the first transmission part 210 on the rotating piece 200 rotates synchronously, so as to exert an abutment force on the second transmission part 310, and then drive the second transmission part 310 to rotate around the first axis R.

[0063] The third transmission part 320 is fixedly connected with the second transmission part 310, which can be integrally formed, or connected by bonding, welding, clamping, screwing or other ways, and the embodiment is not limited specifically. The third transmission part 320 is connected with the cleaning assembly 100, can rotate around the first axis R relative to the cleaning assembly 100, and is limited in the radial direction relative to the cleaning assembly 100, that is, abuts in the radial direction. Since the third transmission part 320 and the overturning axis S form a preset included angle K, when the third transmission part 320 rotates around the first axis R following the second transmission part 310, a radial component force is formed due to the preset included angle K, so that the third transmission part 320 abuts against the cleaning assembly 100 in the radial direction, and pushes the cleaning assembly 100 to rotate around the overturning axis S. Since the second transmission part 310 can rotate around its central axis relative to the first transmission part 210, the movement of the third transmission part 320 in the radial direction is not limited by the second transmission part 310, and when the third transmission part 320 drives the cleaning assembly 100 to rotate around the overturning axis S, the second transmission part 310 synchronously rotates around its central axis. The overturning axis S can be the overturning central axis of the cleaning assembly 100. When the cleaning assembly 100 rotates around the overturning axis S, it overturns relative to the surface to be cleaned, realizes the lifting or lowering relative to the surface to be cleaned, and then separates from or contacts the surface to be cleaned.

[0064] For easy understanding, refer to Figure 7 and Figure 10 When the second transmission part 310 rotates around the first axis R in the direction of R1, the third transmission part 320 rotates following, but since the third transmission part 320 and the overturning axis S form a preset included angle K, and the third transmission part 320 is limited in the radial direction relative to the cleaning assembly 100, the torque of the third transmission part 320 along the first axis R is partially converted into the torque around the central axis of the third transmission part 320 and the abutting force along the first radial direction G, and the abutting force on the first radial direction G acts on the cleaning assembly 100, which is equivalent to that the cleaning assembly 100 receives the tangential force around the overturning axis S, forms the torque around the overturning axis S, and then rotates around the overturning axis S, so that the cleaning assembly 100 overturns, and realizes the lifting and lowering of the cleaning assembly 100.

[0065] Therefore, the embodiment does not need to set a component for lifting and lowering movement in the cleaning device 10 to drive the cleaning assembly 100 to lift and lower, but through the cooperation of the rotating piece 200 and the lifting transmission piece 300, the rotation of the rotating piece 200 around the first axis R is converted into the rotation of the cleaning assembly 100 around the overturning axis S, so that the cleaning assembly 100 can overturn relative to the surface to be cleaned to realize the lifting and lowering, thereby reducing the occupied space of the cleaning device 10, and being beneficial to enhancing the structural compactness and passability of the cleaning equipment.

[0066] In addition, since the screw rod and the threaded sleeve will produce relative sliding in the axial direction when matched, it is easy to produce larger noise and friction, and further affect the service life of the cleaning device 10. The embodiment converts the rotation of the rotating piece 200 around the first axis R into the rotation of the cleaning assembly 100 around the overturning axis S through the cooperation of the rotating piece 200 and the lifting transmission piece 300, reduces the noise and friction, and can improve the service life of the cleaning device 10.

[0067] The cleaning assembly 100 of the embodiment can be an edge brush assembly, which mainly rotates and sweeps through friction with the ground to push garbage to the suction port of the cleaning robot, thereby improving the cleaning effect, but can also be a roller brush assembly, a cloth disc assembly, or a scraper assembly, etc. The surface to be cleaned of the embodiment can be a ground, but can also be a wall surface, a glass surface, etc.

[0068] Referring to Figure 5 In one of the embodiments, the cleaning assembly 100 includes a cleaning part 110 and an overturning part 120, the cleaning part 110 extends away from the first axis R from the overturning part 120 and has a descending position F1 and an ascending position F2 which overturn around the overturning axis S; the overturning part 120 is connected with the third transmission part 320; the third transmission part 320 drives the overturning part 120 to rotate around the overturning axis S when following the second transmission part 310 to rotate around the first axis R, so as to make the cleaning part 110 move between the descending position F1 and the ascending position F2; wherein the first axis R and the overturning axis S are arranged vertically.

[0069] The cleaning part 110 extends away from the first axis R from the overturning part 120 and is arranged close to the surface to be cleaned for cleaning the surface to be cleaned. The cleaning part 110 can include an edge brush which can be provided with bristles for sweeping the surface to be cleaned. The overturning part 120 is fixedly connected with the cleaning part 110 and can be integrally formed, or can be connected by other ways such as bonding, welding, clamping, etc., which are not limited in the embodiment.

[0070] The cleaning part 110 is arranged to overturn around the overturning axis S and has a descending position F1 and an ascending position F2 relative to the surface to be cleaned, when the cleaning part 110 is in the ascending position F2, it is separated from the surface to be cleaned, and when the cleaning part 110 is in the descending position F1, it is in contact with the surface to be cleaned.

[0071] The first axis R and the overturning axis S are arranged perpendicularly, so that the rotation of the rotating member 200 around the first axis R is converted into overturning of the cleaning assembly 100 around the overturning axis S with higher transmission efficiency. In addition, for example, the first axis R can be arranged vertically, perpendicular to the ground when cleaning the surface to be cleaned, and the overturning axis S can be arranged horizontally, parallel to the ground when cleaning the surface to be cleaned. Since the cleaning assembly 100 also needs to rotate synchronously with the rotating member 200 to clean the ground, such an arrangement makes the rotation direction of the rotating member 200 around the first axis R horizontal to the ground, so that the cleaning device 10 keeps contact with or separation from the ground when rotating to clean, without changing in the height direction, resulting in poor cleaning effect or obstacle avoidance effect; and makes the cleaning assembly 100 be able to overturn relative to the ground when rotating around the overturning axis S, to realize lifting.

[0072] For better understanding, refer to Figure 1 and Figure 2 , and Figure 10 and Figure 11 The lowered position F1 can be arranged as the initial position of the cleaning part 110. When the third transmission part 320 moves around the first axis R under the driving of the second transmission part 310, it also abuts against the overturning part 120 along the radial direction G, pushes the overturning part 120 to rotate around the overturning axis S, and drives the cleaning part 110 to rotate synchronously around the overturning axis S, so as to overturn relative to the surface to be cleaned, separate from the surface to be cleaned, and then move from the lowered position F1 to the raised position F2.

[0073] In one of the embodiments, the self-center axis of the second transmission part 310 is the second axis L1, and the self-center axis of the third transmission part 320 is the third axis L2; the second axis L1 is perpendicular to the first axis R and the third axis L2 respectively, and the third axis L2 forms a preset angle K with the overturning axis S; when the first transmission part 210 drives the second transmission part 310 to rotate around the first axis R, the second transmission part 310 rotates synchronously around the second axis L1, so as to drive the third transmission part 320 to overturn the overturning part 120 around the overturning axis S.

[0074] In one of the embodiments, the raised position F2 can include two. Since the rotation of the rotating member 200 around the first axis R is converted into the rotation of the cleaning assembly 100 around the flipping axis S, when the rotating member 200 rotates forwardly, the cleaning assembly 100 can rotate forwardly around the flipping axis S, and when the rotating member 200 rotates reversely, the cleaning assembly 100 can rotate reversely around the flipping axis S. It can be understood that when the cleaning assembly 100 rotates forwardly, it can be flipped upwardly along the clockwise direction, so as to be lifted to the first raised position F2, and when the cleaning assembly 100 rotates reversely, it can be flipped upwardly along the counterclockwise direction, so as to be lifted to the second raised position F2. The lowered position F1 is located between the two raised positions F2, and when the cleaning assembly 100 moves from the first raised position F2 to the second raised position F2, it passes through the lowered position F1.

[0075] Referring to Figure 8 and Figure 9 In one of the embodiments, one of the third transmission part 320 and the flipping part 120 includes a transmission column 321, and the other is provided with a transmission hole 1210; the transmission column 321 is inserted into the transmission hole 1210 and is limited in the radial direction.

[0076] For example, the third transmission part 320 is provided with the transmission column 321, the flipping part 120 is provided with the transmission hole 1210, the transmission column 321 is inserted into the transmission hole 1210 and is limited by the hole wall of the transmission hole 1210 in the radial direction, so that the transmission column 321 abuts against the hole wall of the transmission hole 1210 and drives the hole wall of the transmission hole 1210 to rotate around the flipping axis S, thereby driving the cleaning assembly 100 to rotate around the flipping axis S.

[0077] For example, the third transmission part 320 is provided with the transmission hole 1210, the flipping part 120 is provided with the transmission column 321, the transmission column 321 is inserted into the transmission hole 1210 and is limited by the hole wall of the transmission hole 1210 in the radial direction, when the third transmission part 320 is driven by the second transmission part 310 to rotate, the hole wall of the transmission hole 1210 abuts against the transmission column 321 and drives the transmission column 321 to rotate around the flipping axis S, thereby driving the cleaning assembly 100 to rotate around the flipping axis S.

[0078] Referring to Figure 5 and Figure 9 In one of the embodiments, the flipping part 120 is provided with the transmission hole 1210, and the third transmission part 320 is provided with the transmission column 321; the central axis L3 of the transmission hole 1210 forms a preset included angle K with the first axis R, so that when the transmission column 321 is inserted into the transmission hole 1210, the transmission column 321 forms the preset included angle K with the first axis R; the preset included angle K is an acute angle or an obtuse angle.

[0079] By setting the included angle between the central axis L3 of the transmission hole 1210 and the overturning axis S as the preset included angle K, after the transmission column 321 is assembled in the transmission hole 1210, the third axis L2 of the transmission column 321 coincides with the central axis L3 of the transmission hole 1210, so that the third axis L2 and the overturning axis S form the preset included angle K. Since the first axis R and the overturning axis S are perpendicular, the preset included angle K is set as an acute angle or an obtuse angle, so that the third axis L2 is not coincided with the first axis R, avoiding the transmission column 321 idling in the transmission hole 1210, and unable to form abutting force on the transmission hole 1210, and further unable to drive the overturning part 120 to overturn around the overturning axis S.

[0080] The preset included angle K can be an obtuse angle formed between the third axis L2 and the direction in which the overturning part 120 is connected to the cleaning part 110, so that the overturning can be realized.

[0081] In one of the embodiments, the cleaning assembly 100 further comprises an extension part 130 connected to the overturning part 120 and extending along the overturning axis S in a direction opposite to the cleaning part 110; the cleaning device 10 further comprises a mounting shell 400 for accommodating the cleaning assembly 100, the rotating part 200 and the lifting transmission part 300; wherein the mounting shell 400 is provided with two passages 401 in the rotation direction around the first axis R, and the cleaning part 110 and the extension part 130 are respectively accommodated in the passages 401, and the cleaning part 110 extends out of the mounting shell 400 from the passage 401; the passage 401 and the central axis of the overturning part 120 form the overturning axis S, and the cleaning assembly 100 is rotatably arranged in the passage 401.

[0082] The overturning part 120 has a direction extending towards the cleaning part 110 and a direction away from the cleaning part 110 along the overturning axis S, and since the extension part 130 is accommodated in the passage 401 of the mounting shell 400, it is limited by the mounting shell 400, so that the stability can be improved.

[0083] The preset included angle K can be an acute angle formed between the third axis L2 and the extension part 130, so that the overturning can be realized.

[0084] For ease of understanding, for example, extending towards the cleaning part 110 is positive, and extending away from the cleaning part 110 is negative. The extension part 130 extends from the overturning part 120 in the negative direction and is accommodated in the passage 401, which can reduce the weight difference on both sides of the overturning part 120, which is conducive to improving the stability, and can also limit the overturning part 120 in the passage 401 of the mounting shell 400 to avoid the overturning part 120 from moving along the first axis R.

[0085] Referring to Figure 6In one of the embodiments, the rotating member 200 is provided with a rotating surface 220, and the first transmission part 210 is protruded relative to the rotating surface 220 towards the cleaning assembly 100; the rotating surface 220 and the first transmission part 210 form a rotating space, so that the rotating member 200 can rotate around the first axis R; the first transmission part 210 is provided with an abutting groove, and the side wall of the abutting groove comprises two first abutting surfaces 211 which are distributed along the rotating circumferential direction around the first axis R; the second transmission part 310 comprises an abutting column 311, and the outer cylindrical surface of the abutting column 311 is in abutment with the two first abutting surfaces 211 on both sides along the rotating circumferential direction around the first axis R, and is rotated around the first axis R when subjected to the abutment force of the first abutting surface 211, and is rolled in the abutting groove around the second axis L1 under the driving of the third transmission part 320.

[0086] In the embodiment, the rotating surface 220 can be perpendicular to the first axis R, i.e. parallel to the surface to be cleaned or a horizontal surface, and the rotating space is formed between the rotating surface 220 and the protruded first transmission part 210 to avoid interference with the cleaning assembly 100, so that the rotating member 200 can rotate around the first axis R.

[0087] In the embodiment, the abutting groove of the first transmission part 210 can be a combined groove with a circular-arc-shaped bottom groove and vertical side walls, and the two vertical side walls form the two first abutting surfaces 211, so that the second transmission part 310 can be subjected to the abutment force of the vertical side walls rotating around the first axis R, and can rotate along the second axis L1 relative to the circular-arc-shaped bottom groove. However, it can be understood that the bottom groove can also be horizontally arranged, so that the abutting groove is a groove with a rectangular cross section, or other shapes, as long as the abutting groove can satisfy the abutment with the second transmission part 310 when rotating around the first axis R, and the second transmission part 310 can rotate in the abutting groove. The embodiment does not limit the specific shape.

[0088] In order to realize the rotation of the second transmission part 310, the second transmission part 310 can be provided in a cylindrical shape or a close-to-cylindrical shape of the abutting column 311. When the first transmission part 210 rotates in a positive direction around the first axis R, one of the two first abutting surfaces 211 acts on one side of the outer cylindrical surface of the abutting column 311, and when the first transmission part 210 rotates in a reverse direction around the first axis R, the other of the two first abutting surfaces 211 acts on the other side of the outer cylindrical surface of the abutting column 311, so that the second transmission part 310 can rotate around the first axis R under the action of the two first abutting surfaces 211. When the second transmission part 310 rotates around the first axis R, the third transmission part 320 rotates with the second transmission part 310, but since the third transmission part 320 and the turnover part 120 form a preset included angle K, the third transmission part 320 and the turnover part 120 abut each other in the radial direction, so that the third transmission part 320 has a tendency to drive the turnover part 120 to turn over. Since the abutting column 311 can rotate around the second axis L1, the third transmission part 320 can push the turnover part 120 to turn over, thereby realizing the lifting of the cleaning assembly 100.

[0089] Referring to Figure 6 In one embodiment, the side of the first transmission part 210 away from the first abutting surface 211 is provided with a limiting surface 212. The limiting surface 212 is used to abut and limit the cleaning assembly 100 or the mounting shell 400 when rotating around the first axis R to a preset position.

[0090] The shape of the limiting surface 212 can correspond to the first abutting surface 211, but can also be different, which is not limited in the embodiment. The limiting surface 212 can abut and limit the mounting shell 400 or the cleaning assembly 100 when rotating in a positive direction or a reverse direction around the first axis R. The mounting shell 400 can be provided with a limiting structure, for example, limiting the mounting shell 400 in the positive direction and the reverse direction, or limiting the mounting shell 400 in the positive direction and limiting the cleaning assembly 100 in the reverse direction, or limiting the cleaning assembly 100 in the positive direction and the reverse direction.

[0091] In one of the embodiments, the limiting surface 212 is arranged to abut against the cleaning assembly 100 when moving forward or reversely around the first axis R, and is limited by the cleaning assembly 100. Since the turnover portion 120 of the cleaning assembly 100 has a part extending towards the cleaning portion 110, and the opposite extension portion 130, the cleaning assembly 100 can be arranged in the rotating space formed by the rotating surface 220 and the first transmission portion 210. When the rotating surface 220 of the rotating member 200 rotates, the limiting surface 212 rotates synchronously with the rotating surface 220, and is limited by the part of the turnover portion 120 extending to the cleaning portion 110 when moving forward to the preset position, and is limited by the cleaning assembly 100 when moving reversely to the extension portion 130, so that the turnover portion 120 is limited, and the lifting transmission member 300 and the rotating member 200 no longer move relatively, and the cleaning assembly 100 and the lifting transmission member 300 can rotate synchronously with the rotating member 200 around the first axis R. In this way, the limiting structure does not need to be arranged separately on the mounting shell 400, but the limiting is realized by using the structure of the cleaning assembly 100 itself, which improves the compactness, is beneficial to optimizing the use space of the cleaning device 10, and is also beneficial to reducing the production cost.

[0092] Referring to Figure 4 In one of the embodiments, the mounting shell 400 includes an upper cover 410 and a lower cover 420, and the upper cover 410 and the lower cover 420 are fixedly connected. The lower cover 420 is provided with a rolling groove 402, and the rolling groove 402 is in communication with the channel 401. The rolling groove 402 is in contact with the abutting column 311, and a movement gap is formed between the rolling groove 402 and the turnover portion 120.

[0093] The upper cover 410 and the lower cover 420 can be fixedly connected by clamping or adhesion. The lower cover 420 can be provided with the rolling groove 402 on the inner side surface facing the upper cover 410. The rolling groove 402 can be parallel to the surface to be cleaned and the rotating surface 220, and can be a circular groove. The abutting column 311 can abut against the rolling groove 402 under the action of gravity. When the abutting column 311 rotates around the second axis L1, it is equivalent to rolling on the groove bottom surface of the rolling groove 402.

[0094] The movement gap enables the turnover portion 120 to rotate relative to the rolling groove 402 around the turnover axis S, so that the turnover and lifting of the cleaning assembly 100 can be realized.

[0095] Referring to Figure 7In one of the embodiments, the lifting transmission member 300 further comprises a connecting portion 330, two ends of the connecting portion 330 are connected with the second transmission portion 310 and the third transmission portion 320 respectively; one end of the connecting portion 330 connected with the second transmission portion 310 forms a right angle with the second transmission portion 310, one end of the connecting portion 330 connected with the third transmission portion 320 forms a right angle with the third transmission portion 320, and a right angle is formed between the two ends of the connecting portion 330, so that the central axis of the second transmission portion 310 is perpendicular to the central axis of the third transmission portion 320.

[0096] By connecting the second transmission portion 310 and the third transmission portion 320 through the connecting portion 330, and forming right angles at both ends, the central axis of the second transmission portion 310 is perpendicular to the central axis of the third transmission portion 320, so that the movement of the third transmission portion 320 in the radial direction is equivalent to the rotation of the second transmission portion 310 around its own central axis, so as to rotate the third transmission portion 320 and the second transmission portion 310 around the axis of the second transmission portion 310.

[0097] In one of the embodiments, the central axis of the second transmission portion can be the second axis L1, and the central axis of the third transmission portion can be the third axis L2.

[0098] In one of the embodiments, the second transmission portion 310 is formed in two in the rotation direction around the first axis R, the two second transmission portions 310 are distributed on both sides of the flipping axis S, and the extension lines of the two second transmission portions 310 coincide and are perpendicular to the first axis R; the first transmission portion 210 is formed in two in the rotation direction around the first axis R, and the two first transmission portions 210 are respectively used to abut against the corresponding two second transmission portions 310. Figure 8 Figure 9 In one of the embodiments, the second transmission portion 310 is formed in two in the rotation direction around the first axis R, the two second transmission portions 310 are distributed on both sides of the flipping axis S, and the extension lines of the two second transmission portions 310 coincide and are perpendicular to the first axis R; the first transmission portion 210 is formed in two in the rotation direction around the first axis R, and the two first transmission portions 210 are respectively used to abut against the corresponding two second transmission portions 310.

[0099] In one of the embodiments, the second transmission portion 310 is formed in two in the rotation direction around the first axis R, the two second transmission portions 310 are distributed on both sides of the flipping axis S, and the extension lines of the two second transmission portions 310 coincide and are perpendicular to the first axis R; the first transmission portion 210 is formed in two in the rotation direction around the first axis R, and the two first transmission portions 210 are respectively used to abut against the corresponding two second transmission portions 310.

[0100] In order to facilitate understanding, the first axis R and the flipping axis S intersect to form a center point, and the second transmission portion 310 and the first transmission portion 210 are symmetrically arranged relative to the center point, which effectively improves the stability of the transmission and avoids uneven stress, thereby improving the working stability and service life of the cleaning device 10.
