Description

Technical Field

[0001] The invention relates to a cleaning device, in particular to a docking assembly and a cleaning system. Background Art

[0002] Traditional household cleaning systems generally include a base station and cleaning equipment. The base station can be used to replenish cleaning liquids, such as water and detergent, for the cleaning equipment, so that the cleaning equipment can continue to clean. Some base stations are equipped with a guide docking structure when supplying liquid to the cleaning equipment, but it is difficult to accurately align the docking point between the base station and the cleaning equipment. When the sweeping robot is aligned with the protruding docking platform on the base station in an inclined state, the water supply port on the base station cannot be accurately used to dock with the docking port of the sweeping and mopping robot. The docking port will leak, and the sweeping and mopping robot cannot complete normal water replenishment. At the same time, the leaking water will also pollute the ground.

[0003] The water supply port of some products in the prior art is fixed. When the sweeping and mopping robot needs to be watered, it usually uses infrared, laser and other sensors to locate the position of the base station. The sweeping and mopping robot passes through the slope in front of the docking cavity of the base station and enters the docking cavity. When the docking detection element located at the base station detects that the docking is successful, it will then replenish water, otherwise it will leave the station and re-align. However, the positioning of infrared, laser and other sensors is skewed (the design deflection range of the infrared positioning device is ±3° left and right), which will cause the alignment of the sweeping and mopping robot's water supply interface and the base station's water supply port to be skewed, so it needs to be re-positioned multiple times, which leads to low water supply efficiency and further low cleaning efficiency.

[0004] Although there is a cleaning system disclosed in the prior art such as the invention application with application publication number CN114365971A, which can make the water replenishment interface of the base station movably arranged, and mainly uses the conical protrusion and conical hole structure for positioning, although the conical protrusion structure adopts elastic material, when the horizontal angle between the axis of the conical protrusion and the axis of the conical hole is too large, it will get stuck. In addition, since the bottom plate supporting the sweeping and mopping robot is in direct contact with the ground, if the ground is uneven, it may cause the vertical angle between the axis of the conical protrusion and the axis of the conical hole to be too large, and it will also get stuck. If the wheel or the single side of the supporting bottom plate in contact with the wheel is adhered or accumulated with foreign matter of a certain height, it will also cause the sweeping and mopping robot to tilt and get stuck. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems and provide a docking assembly which has a large degree of freedom in docking activities, can tolerate a large docking deviation, and ensure a successful docking in one go.

[0006] Another object of the present invention is to provide a cleaning system.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A docking assembly comprises a docking mounting seat, a liquid supply pipe and an adaptive elastic member;

[0009] The docking mounting seat is fixedly arranged on the base station, and a hollow mounting inner cavity is provided on the docking mounting seat, and a side wall of the mounting inner cavity is provided with at least two first mounting grooves;

[0010] One end of the liquid supply pipe extends into the mounting inner cavity of the docking mounting seat and is connected to the liquid replenishing pipe of the cleaning device. At least two second mounting grooves are provided on one end of the liquid supply pipe.

[0011] There are at least two adaptive elastic members; one end of the adaptive elastic member extends into the first installation groove, and the other end of the adaptive elastic member extends into the second installation groove.

[0012] The working principle of the above docking assembly is:

[0013] When the sweeping and mopping robot needs to replenish cleaning fluid during operation, it will actively approach the base station and dock the pipeline with the base station to complete the filling. During the docking process, the sweeping and mopping robot will align the refilling tube with the liquid supply tube of the base station and shorten the distance between the two so that the refilling tube and the liquid supply tube can be successfully docked. Among them, since at least two adaptive elastic parts are provided between the docking mounting seat and the liquid supply tube, and one end of the adaptive elastic part extends into the first mounting groove and the other end extends into the second mounting groove; when subjected to radial external force (at this time, the refilling tube and the liquid supply tube may not be successfully docked and there is a position deviation), the adaptive elastic part is compressed and deformed along the direction of the external force, so that the liquid supply tube can move in this direction in an adaptive position and adjust its own posture, thereby ensuring that the refilling tube and the liquid supply tube are successfully docked.

[0014] In a preferred embodiment of the present invention, the first installation grooves and the second installation grooves are evenly arranged along the circumferential direction; the adaptive elastic members are evenly arranged along the circumferential direction;

[0015] The planes formed by the arrangement of the first mounting groove and the second mounting groove are both perpendicular to the axis of the liquid supply pipe.

[0016] Furthermore, the adaptive elastic member is a U-shaped structure.

[0017] Furthermore, the adaptive elastic member includes two straight portions parallel to each other and a bend portion connected between the two straight portions; the two straight portions are respectively located in the first mounting groove and the second mounting groove. Through the above structure, when subjected to radial external force, the two straight portions in the corresponding direction will be squeezed and moved closer to each other, thereby providing space for position adjustment for the liquid supply pipe to smoothly complete the docking.

[0018] Furthermore, the mounting inner cavity of the docking mounting seat is a cross-shaped structure; and four of each of the first mounting groove, the second mounting groove and the adaptive elastic member are provided.

[0019] Furthermore, a triangular boss is provided on the outer side of one of the straight portions. Thus, making the side of the straight portion into an inclined surface can reduce the decomposition of the tilting force, so that the displacement of the adaptive elastic member is more accurate.

[0020] Further, the adaptive elastic member includes two straight portions parallel to each other and a turning portion connected between the two straight portions;

[0021] The ends of the two straight portions extend into the first mounting groove, and the bent portion extends into the second mounting groove; the second mounting groove is a structure conforming to the outer side surface of the bent portion.

[0022] Furthermore, there are two of each of the first mounting slots, the second mounting slots and the adaptive elastic member; the two first mounting slots, the two second mounting slots and the two adaptive elastic members are located on the same horizontal plane; and the two straight portions of the adaptive elastic member are arranged vertically.

[0023] Through the above structure, when the liquid supply pipe is subjected to a vertical force, the force will be transmitted to the two side surfaces of the adaptive elastic member. For example, when the liquid supply pipe is subjected to a downward force, the downward force is transmitted to the two side surfaces of the adaptive elastic member, and the two side surfaces will deform downward, completing the vertical movement of the liquid supply pipe. Furthermore, since the straight portion of the adaptive elastic member is not completely inserted into the first mounting groove, the purpose is to allow the two side surfaces without support below to deform.

[0024] In a preferred embodiment of the present invention, the adaptive elastic member is a U-shaped structure, and the adaptive elastic member includes two mutually parallel straight portions and a turning portion connected between the two straight portions;

[0025] A connecting platform is provided on the narrow side surface of one of the straight portions, and the connecting platform extends obliquely from the narrow side surface toward the outer wide side surface;

[0026] The connecting platform is installed in the second installation groove, and the other straight portion is installed in the first installation groove.

[0027] Furthermore, there are two of each of the first mounting slot, the second mounting slot and the adaptive elastic member; the two adaptive elastic members are symmetrically arranged; and the connecting platforms of the two adaptive elastic members extend along the horizontal direction and are located on the same horizontal plane.

[0028] In a preferred embodiment of the present invention, the first mounting grooves are provided in two groups, and each group of first mounting grooves includes two first mounting grooves;

[0029] There are two of each of the second mounting slots and the adaptive elastic member; the two adaptive elastic members are symmetrically arranged;

[0030] The adaptive elastic member includes two straight portions and a semicircular portion connected between the two straight portions; the two straight portions are located on the same straight line; the semicircular portion extends into the second mounting groove, and the second mounting groove is a structure conforming to the outer side surface of the semicircular portion;

[0031] Ends of the two straight portions extend into two first mounting grooves of the same group.

[0032] A cleaning system comprises a cleaning base station and a sweeping and mopping robot; the cleaning base station is provided with the docking assembly.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The docking assembly of the present invention has a large degree of freedom in docking activities and can tolerate a large docking deviation, thus ensuring successful docking in one go.

[0035] 2. By setting an adaptive elastic member, the liquid supply pipe can be moved up and down, left and right, and at an inclined angle. In the prior art, the liquid supply pipe and the base station cannot move relative to each other or can only move in a single direction. Therefore, the present invention can handle the situation of docking offset at various angles. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0046] Example 1

[0047] See also Figure 1-3 The cleaning system of this embodiment includes a cleaning base station 1 and a sweeping and mopping robot 2; the cleaning base station 1 is provided with a docking assembly, which includes a docking mounting seat 3, a liquid supply pipe 4 and an adaptive elastic member 5; the docking mounting seat 3 is fixedly arranged on the cleaning base station 1, and a hollow mounting inner cavity is provided on the docking mounting seat 3, and the side wall of the mounting inner cavity is provided with at least two first mounting grooves 3-1 evenly arranged along the circumferential direction; the plane formed by the arrangement of the first mounting grooves 3-1 is perpendicular to the axis of the liquid supply pipe 4; one end of the liquid supply pipe 4 extends into the mounting inner cavity of the docking mounting seat 3, and is used to communicate with the liquid replenishment pipe of the sweeping and mopping robot 2, and at least two second mounting grooves 4-1 evenly arranged along the circumferential direction are provided on one end of the liquid supply pipe 4; the plane formed by the arrangement of the second mounting grooves 4-1 is perpendicular to the axis of the liquid supply pipe 4; at least two adaptive elastic members 5 are provided, and the adaptive elastic members 5 are evenly arranged along the circumferential direction; one end of the adaptive elastic member 5 extends into the first mounting groove 3-1, and the other end of the adaptive elastic member 5 extends into the second mounting groove 4-1.

[0048] See also Figure 2-3 The adaptive elastic member 5 is a U-shaped structure, and includes two straight portions parallel to each other and a turning portion connected between the two straight portions; the two straight portions are respectively located in the first mounting groove 3-1 and the second mounting groove 4-1. Through the above structure, when subjected to radial external force, the two straight portions in the corresponding direction will be squeezed and moved closer to each other, thereby providing space for the position adjustment of the liquid supply pipe 4, so as to successfully complete the docking.

[0049] Furthermore, the mounting inner cavity of the docking mounting seat 3 is a cross-shaped structure; the first mounting groove 3 - 1 , the second mounting groove 4 - 1 and the adaptive elastic member 5 are each provided with four.

[0050] See also Figure 4 , the outer side surface of one of the straight parts is provided with a triangular boss 5-1. In this way, making the side surface of the straight part into an inclined surface can reduce the decomposition of the tilting force, so that the displacement of the adaptive elastic member 5 is more accurate.

[0051] See also Figure 2-3 , the working principle of the docking assembly of this embodiment is:

[0052] When the sweeping and mopping robot 2 needs to replenish the cleaning liquid during operation, it will actively approach the base station and dock the pipeline with the base station to complete the filling. During the docking process, the sweeping and mopping robot 2 will align the liquid replenishment tube with the liquid supply tube 4 of the base station and shorten the distance between the two, so that the liquid replenishment tube and the liquid supply tube 4 are successfully docked. Among them, since at least two adaptive elastic parts 5 are provided between the docking mounting seat 3 and the liquid supply tube 4, and one end of the adaptive elastic part 5 extends to the first mounting groove 3-1, and the other end extends to the second mounting groove 4-1; when subjected to radial external force (at this time, the liquid replenishment tube and the liquid supply tube 4 may not be successfully docked, and there is a position deviation), the adaptive elastic part 5 is compressed and deformed along the direction of the external force, so that the liquid supply tube 4 can be adaptively moved in this direction and adjust its own posture, thereby ensuring that the liquid replenishment tube and the liquid supply tube 4 are docked.

[0053] Example 2

[0054] See also Figure 5-6 , which is different from the first embodiment, the ends of the two straight portions of the present embodiment extend into the first mounting groove 3-1, and the bent portion extends into the second mounting groove 4-1; the second mounting groove 4-1 is a structure conforming to the outer side surface of the bent portion. The present embodiment has a simplified structure, 4 adaptive elastic members 52, and the degree of freedom of vertical movement is slightly greater than the degree of freedom of horizontal movement.

[0055] Furthermore, there are two of each of the first mounting groove 3-1, the second mounting groove 4-1 and the adaptive elastic member 5; the two first mounting grooves 3-1, the two second mounting grooves 4-1 and the two adaptive elastic members 5 are located on the same horizontal plane; and the two straight portions of the adaptive elastic member 5 are arranged vertically.

[0056] Through the above structure, when the liquid supply pipe 4 is subjected to a vertical force, the force will be transmitted to the two side surfaces of the adaptive elastic member 5. For example, when the liquid supply pipe 4 is subjected to a downward force, the downward force is transmitted to the two side surfaces of the adaptive elastic member 5, and the two side surfaces will deform downward to complete the vertical movement of the liquid supply pipe 4. Furthermore, since the straight portion of the adaptive elastic member 5 is not completely inserted into the first mounting groove 3-1, the purpose is to allow the two side surfaces to deform without support below.

[0057] Example 3

[0058] See also Figure 7-8, which is different from Example 1, a connecting platform 6 is provided on the narrow side of one of the straight portions of this embodiment, and the connecting platform 6 extends obliquely from the narrow side toward the outer wide side; the connecting platform 6 is installed in the second installation groove 4-1, and the other straight portion is installed in the first installation groove 3-1.

[0059] Furthermore, there are two of each of the first mounting groove 3 - 1 , the second mounting groove 4 - 1 and the adaptive elastic member 5 ; the two adaptive elastic members 5 are symmetrically arranged; and the connecting platforms 6 of the two adaptive elastic members 5 extend in the horizontal direction and are located on the same horizontal plane.

[0060] Example 4

[0061] See also Fig. 9 , which is different from Example 1, the first mounting groove 3-1 of this embodiment is provided with two groups, and each group of first mounting grooves 3-1 includes two first mounting grooves 3-1; the second mounting groove 4-1 and the adaptive elastic member 5 are each provided with two; the two adaptive elastic members 5 are symmetrically arranged; the adaptive elastic member 5 includes two straight portions and a semicircular portion connected between the two straight portions; the two straight portions are located on the same straight line; the semicircular portion extends into the second mounting groove 4-1, and the second mounting groove 4-1 is a structure that imitates the outer side surface of the semicircular portion; the ends of the two straight portions extend into the two first mounting grooves 3-1 of the same group.
