Description

Technical Field

[0001] The present invention relates to the technical field of sweeping robots, in particular to a base station and a sweeping robot. Background Art

[0002] A robot vacuum is a cleaning tool that can automatically clean the floor. A robot vacuum with a self-cleaning function can automatically clean the wastewater generated during the sweeping process and automatically replenish clean water. After the robot vacuum is finished sweeping, it returns to the base station. The wastewater discharge connector on the robot vacuum connects to the wastewater connector in the base station, and the clean water input connector on the robot vacuum connects to the water supply connector in the base station. Wastewater generated by the robot vacuum enters the base station through the wastewater connector, and clean water is replenished into the robot vacuum through the water supply connector in the base station. Due to manufacturing errors, the robot vacuum may deviate from the base station when entering the station, resulting in poor sealing of the various connectors. Summary of the Invention

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figures 1 to 4 As shown, in some embodiments, a base station 10 is provided, comprising a first docking connector 12, a base station body 11, a first elastic reset unit 13 and a second elastic reset unit 15. The first docking connector 12 is provided on the base station body 11, and the first docking connector 12 can move back and forth within a preset range along a first direction relative to the base station body 11. Specifically, Figures 1 to 4 At the angle shown, the first direction is the direction shown by the arrow L1, the direction opposite to the first direction is the second direction, and the second direction is the direction shown by the arrow L2.

[0036] Specifically in one embodiment, the first docking connector 12 can move within a preset range in the horizontal direction relative to the base station body 11, the first direction is a direction in the horizontal direction, and the second direction is a direction opposite to the first direction in the horizontal direction. Figures 1 to 3 At the angle shown, the first docking connector 12 has a certain margin of movement back and forth relative to the base station body 11 along the first direction. When the sweeping robot host enters the station, even if there is a certain offset in the first direction relative to the base station 10, the connector on the sweeping robot host can dock and seal with the first docking connector 12.

[0037] Specifically, the first elastic reset unit 13 acts between the base station body 11 and the first docking connector 12, and is used to provide an elastic reset force for the first docking connector 12 to move in a first direction relative to the base station body 11. The second elastic reset unit 15 acts between the base station body 11 and the first docking connector 12, and is used to provide an elastic reset force for the first docking connector 12 to move in a second direction relative to the base station body 11.

[0038] When the robot vacuum cleaner enters the station, the connector on the robot vacuum cleaner needs to dock with the first docking connector 12. Even if the connector on the robot vacuum cleaner is slightly offset from the first docking connector 12, the first docking connector 12 can overcome the elastic force of the first elastic reset unit 13 and the second elastic reset unit 15 to dock and seal with the connector on the robot vacuum cleaner. When the robot vacuum cleaner leaves the station, the first docking connector 12 is freed from the connector on the robot vacuum cleaner and reset under the action of the two elastic reset units, preparing for the next entry of the robot vacuum cleaner. This ensures the tightness of the docking between the connector on the robot vacuum cleaner and the first docking connector 12 on the base station 10 to prevent water leakage.

[0039] In some embodiments, the first docking connector 12 is a water supply connector 123, which is used to connect to the connector on the robot vacuum cleaner to provide the robot vacuum cleaner with the liquid required for cleaning. The water supply connector 123 is connected to the cleaning water tank on the base station body 11.

[0040] In other embodiments, the first docking connector 12 is a sewage connector 124, which is used to dock with a connector on the robot vacuum cleaner to suck away sewage generated by the robot vacuum cleaner during the sweeping process. The sewage connector 124 is connected to a sewage tank on the base station body 11.

[0041] Of course, in some embodiments, the base station 10 may include two first docking connectors 12, such as Figures 1 to 4 As shown, one of the first docking joints 12 is a water supply joint 123 , and the other first docking joint 12 is a sewage joint 124 .

[0042] The first elastic reset unit 13 and the second elastic reset unit 15 form a set of elastic reset mechanisms. The base station 10 includes two elastic reset mechanisms. The water supply connector 123 corresponds to one elastic reset mechanism, and the sewage connector 124 corresponds to the other elastic reset mechanism.

[0043] The water supply joint 123 can be elastically reset in the first direction or the second direction under the action of the two elastic reset units included in the corresponding elastic reset mechanism. One of the two elastic reset units here is the first elastic reset unit 13, which is used to provide the water supply joint 123 with an elastic reset force for moving along the first direction relative to the base station body 11, and the other is the second elastic reset unit 15, which is used to provide the water supply joint 123 with an elastic reset force for moving along the second direction relative to the base station body 11.

[0044] The sewage connector 124 can be elastically reset in the first direction or the second direction under the action of the two elastic reset units included in the corresponding elastic reset mechanism. One of the two elastic reset units 13 here is the first elastic reset unit 13, which is used to provide the sewage connector 124 with an elastic reset force for moving along the first direction relative to the base station body 11, and the other is the second elastic reset unit 15, which is used to provide the sewage connector 124 with an elastic reset force for moving along the second direction relative to the base station body 11.

[0045] Specifically in one embodiment, Figure 2 、 Figure 5 and Figure 6 As shown, both the first elastic reset unit 13 and the second elastic reset unit 15 include an elastic arm 131, which is provided on the first docking connector 12 and abuts against the base station body 11. The elastic arm 131 acts between the first docking connector 12 and the base station body 11 to provide an elastic reset force for the first docking connector 12 to reset relative to the base station body 11. The elastic arm 131 included in the first elastic reset unit 13 is used to provide an elastic reset force for the first docking connector 12 to move in a first direction relative to the base station body 11, and the elastic arm 131 included in the second elastic reset unit 13 is used to provide an elastic reset force for the first docking connector 12 to move in a second direction relative to the base station body 11.

[0046] The connection between the elastic arm 131 and the first butt joint 12 includes: the elastic arm 131 is directly connected to the first butt joint 12, or as follows Figure 4 and Figure 5 The elastic arm 131 is indirectly connected to the first docking joint 12. Figure 4 and Figure 5In the illustrated embodiment, a stop protrusion is provided on the outer circumference of the first docking connector 12. The stop protrusion is annular in structure. One end of the elastic arm 131 is connected to the stop protrusion, and the other end of the elastic arm 131 is suspended outside the stop protrusion and abuts against the base station body 11. In some embodiments, the elastic arm 131, the stop protrusion, and the first docking connector 12 are integrally injection-molded.

[0047] like Figure 2 、 Figure 5 and Figure 6 As shown, in one embodiment, one end of the elastic arm 131 is connected to the first docking joint 12, and the other end of the elastic arm 131 is suspended outside the first docking joint 12. The elastic arm 131 is at least partially bent along the circumference of the first docking joint 12, and the end of the elastic arm 131 suspended outside the first docking joint 12 is in contact with the base station body 11.

[0048] When the first docking connector 12 is docked with the connector on the robot main body and deviates in the first or second direction, the elastic arm 131 deforms. After the first docking connector 12 is separated from the connector on the robot main body, the elastic arm 131 recovers its shape, thereby providing elastic restoring force for the first docking connector 12 to return to its original position.

[0049] like Figure 6 As shown, the portion of the elastic arm 131 that is bent along the circumference of the first butt joint 12 is spaced apart from the first butt joint 12. When the elastic arm 131 is subjected to extrusion force, this portion of the elastic arm 131 completes the bending deformation, and the distance between the end of the elastic arm 131 hanging outside the first butt joint 12 and the first butt joint 12 is reduced.

[0050] In one embodiment, Figure 3 The first docking connector 12 is shown as having a preset unilateral movable distance d1 for moving back and forth in the first direction relative to the base station body 11. Figure 6 The maximum deformation distance d2 that the end of the elastic arm 131 that overhangs the first docking connector 12 can move toward the first docking connector 12 is allowed, where d2 ≥ d1. The allowable deformation range of the elastic arm 131 is no less than the preset range of motion of the first docking connector 12 relative to the base station body 11, ensuring that the first docking connector 12 can move within the preset range relative to the base station body 11.

[0051] It should be noted that when the first butt joint 12 and the elastic arm 131 are indirectly connected via the stop protrusion, the minimum distance between the end of the elastic arm 131 that overhangs the first butt joint 12 and the stop protrusion is d2, and d2 ≥ d1. When the first butt joint 12 and the elastic arm 131 are directly connected, the minimum distance between the end of the elastic arm 131 that overhangs the first butt joint 12 and the first butt joint 12 is d2, and d2 ≥ d1.

[0052] like Figure 6 As shown, the portion of the elastic arm 131 that bends along the circumference of the first butt joint 12 is an elastic section 1313 . The elastic sections 1313 are arranged at intervals around the stop protrusion. The minimum distance between the elastic sections 1313 and the stop protrusion is d2 , and d2 ≥ d1 .

[0053] Furthermore, if Figure 5 and Figure 6 As shown, in some embodiments, the first elastic reset unit 13 and the second elastic reset unit 15 each include two elastic arms 131, one end of the elastic arm 131 connected to the first butt joint 12 is a fixed end 1311, and the other end of the elastic arm 131 suspended outside the first butt joint 12 is a cantilevered end 1312. The fixed ends 1311 of the two elastic arms 131 belonging to the same elastic reset unit are arranged at intervals along the circumference of the first butt joint 12, and the two elastic arms 131 are bent toward each other so that the distance between the two cantilevered ends 1312 is smaller than the distance between the two fixed ends 1311. Figure 5 and Figure 6 As shown, the first elastic reset unit 13 includes two elastic arms 131 spaced apart along the circumference of the first butt joint 12. These two elastic arms 131 bend toward each other so that the distance between the two overhanging ends 1312 is smaller than the distance between the two fixed ends 1311. The second elastic reset unit 15 includes two elastic arms 131 spaced apart along the circumference of the first butt joint 12. These two elastic arms 131 bend toward each other so that the distance between the two overhanging ends 1312 is smaller than the distance between the two fixed ends 1311. The first butt joint 12 is supported by the two elastic arms 131 on one side, providing a more stable and reliable force.

[0054] Specifically, in some embodiments, Figure 2 As shown, the base station body 11 is provided with at least two limiting ribs 14, each having an abutting portion. One limiting rib 14 corresponds to the first elastic reset unit 13, and the abutting portion of this limiting rib 14 abuts against the overhanging ends 1312 of the two elastic arms 131 included in the first elastic reset unit 13, and this abutting portion is located on the side of the overhanging end 1312 away from the first docking joint.

[0055] The other limiting rib 14 corresponds to the second elastic reset unit 15, and the abutment portion of this limiting rib 14 abuts against the overhanging ends 1312 of the two elastic arms 131 included in the second elastic reset unit 15, and this abutment portion is located on the side of this overhanging end 1312 away from the first docking joint.

[0056] Each elastic reset unit corresponds to a limiting rib 14 , and the abutting portion abuts against the overhanging ends 1312 of the two elastic arms 131 included in the corresponding elastic reset unit 13 , and the abutting portion abuts against the side of the corresponding overhanging end 1312 away from the first docking joint 12 .

[0057] The base station body 11 is in indirect contact with the elastic reset unit via the limiting rib 14 , and the two elastic arms 131 belonging to the same elastic reset unit are both in contact with the same limiting rib 14 .

[0058] In one embodiment, the abutting portion is a partial rib segment on the limiting rib 14, the length direction of which is parallel to the length direction of the elastic segment 1313 of the elastic arm 131, and which abuts against the elastic segments 1313 of the two elastic arms 131 of the corresponding elastic reset unit.

[0059] Furthermore, if Figures 1 to 4 As shown, in some embodiments, the base station body 11 includes a housing 111, which encloses a cavity 117 for accommodating the main unit of the robot vacuum cleaner. The side of the cavity 117 is the outer side 115 of the housing 111, and the side facing away from the cavity 117 is the inner side 114 of the housing 111. The first docking connector 12 extends through the housing 111, such that one end of the first docking connector 12 is located on the outer side 115 of the cavity 117 and the other end of the first docking connector 12 is located on the inner side 114 of the housing 111. The first elastic reset unit 13 and the second elastic reset unit 15 are both located on the inner side 114 of the housing 111. When viewed from the side of the cavity 117, the first elastic reset unit 13 and the second elastic reset unit 15 are both shielded by the housing 111.

[0060] like Figure 4 As shown, the stop protrusion provided on the outside of the first butt joint 12 is also located on the inner side 114 of the housing 111, and the stop protrusion and the elastic reset unit 13 are located on the same side of the housing 111. The stop protrusion can abut against the housing 111 to limit the movement of the first butt joint 12 relative to the housing 111 into the accommodating cavity 117.

[0061] Furthermore, in one embodiment, Figure 4 and Figure 5 As shown, the outer peripheral surface of the first docking joint 12 is provided with a first stop portion 121 and a second stop portion 122, the first stop portion 121 is located on the outer side 115 of the shell 111, and the second stop portion 122 is located on the inner side 114 of the shell 111, and the first elastic reset unit 13 and the second elastic reset unit 15 are both connected to the second stop portion 122.

[0062] The stop protrusion in the aforementioned embodiments is the second stop portion 122. Under the restriction of the first stop portion 121 and the second stop portion 122, the first butt joint 12 cannot move relative to the housing 111 in the spacing direction of the first stop portion 121 and the second stop portion 122.

[0063] Specifically, if Figures 1 to 4 As shown, the base station body 11 includes an upper cover 112 and a base 113. The upper cover 112 is disposed on the base 113, and the first docking connector 12 is disposed at the junction of the upper cover 112 and the base 113. A portion of the housing 111 is attached to the upper cover 112, while another portion of the housing 111 is attached to the base 113. The structure formed by the connection of the upper cover 112 and the base 113 includes the aforementioned housing 111. U-shaped grooves are provided on both the upper cover 112 and the base 113 for securing the first docking connector 12. During installation, the first docking connector 12 can be placed into the U-shaped groove on the base 113, ensuring that the first stopper 121 is located on the outside 115 of the housing 111 and the second stopper 122 is located on the inside 114 of the housing 111. The upper cover 112 is then mounted on the base 113. The U-shaped grooves of the upper cover 112 and the base 113 together form a mounting hole 116 for mounting the first docking connector 12.

[0064] Furthermore, in one embodiment, Figure 2 and Figure 5 As shown, the first elastic reset unit 13 and the second elastic reset unit 15 are symmetrically arranged relative to the first butt joint 12. One elastic reset unit 13 is located on the left side of the first butt joint 12, and the other elastic reset unit 13 is located on the right side of the first butt joint 12.

[0065] Furthermore, in another embodiment, a sweeping machine is provided, including a sweeping robot host and the above-mentioned base station 10. The sweeping robot host is provided with a second docking connector, and the sweeping robot host can return to the base station body 11 and make the second docking connector docked and connected with the first docking connector 12.

[0066] Two elastic reset units are used to provide the first docking connector 12 with elastic reset forces in the first and second directions, so that even if there is a position deviation when the sweeping robot returns to the station, the second docking connectors on the sweeping robot host can be accurately docked with the first docking connector 12 on the base station 10, ensuring the sealing of the docking between the connectors and avoiding water leakage.
