[0075] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0077] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0078] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0079] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0080] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0081] An AGV is an unmanned transport vehicle with the purpose of loading and unloading, position sensing capability, the ability to autonomously plan routes and drive automatically, and the ability to expand functions. The power source of a mobile robot is generally a rechargeable battery. When the mobile robot is working, the detection system on the robot will continuously detect the remaining battery power. When the remaining power is lower than the set value, the mobile robot will temporarily change the destination to the designated charging pile position, docking the charging pile with the charging port of the vehicle body, thereby charging the mobile robot. Due to the combined errors of the visual system, control system and mechanical structure, it is difficult for the mobile robot to accurately locate when it reaches the charging position. Therefore, the charging equipment needs to be provided with a floating docking mechanism to accommodate the positioning error of the mobile robot. However, the lateral floating of the existing floating docking mechanism uses a slide rail, which cannot solve the angle error problem when the mobile robot is docked, and the structure is generally complex and the manufacturing cost is high.

[0082] Figures 1 to 6 A charging docking device provided by the utility model is shown, which realizes compensation of the angular error of the mobile robot by the floating docking mechanism when floating laterally, and meets the docking requirements. The charging docking device includes a base 10, a first connector 20, a second connector 30 and a charging docking terminal 50. The first connector 20 is rotatably connected to the base 10 around a first rotation axis AX1. The second connector 30 is movably connected to the first connector 20 along a first direction D1, and the second connector 30 can rotate with the rotation of the first connector 20, and the first rotation axis AX1 is not parallel to the first direction D1. The charging docking terminal 50 is connected to the second connector 30. In the utility model, the second connector 30 moves relative to the first connector 20, so the first connector 20 can provide a track for the second connector 30 to move. The second connector 30 can rotate with the rotation of the first connector 20, so that the charging docking terminal 50 can be deflected. The first rotation axis AX1 is not parallel to the first direction D1 , and when the second connector 30 is moved by force, the charging docking terminal 50 can be deflected according to the direction of the force, so as to better adapt to the posture and position of the mobile robot.

[0083] Optionally, the base 10 is configured as a plate-like structure. The base 10 includes a first base 11 and a second base 12 arranged at intervals along the first rotation axis AX1. Optionally, the charging docking device includes a shell. The base 10 is arranged in the shell, and the base 10 can also be a part of the shell.

[0084] The first connecting member 20 is installed between the first base 11 and the second base 12 via a rotating shaft. Specifically, the first connecting member 20 is rotatably connected to the first base 11 via a first rotating shaft 22. The first connecting member 20 is rotatably connected to the second base 12 via a second rotating shaft 23.

[0085] Specifically, the first connecting member 20 includes a steering plate 21 and a rotating shaft. The rotating shaft is connected to the steering plate 21, and the steering plate 21 is rotatably connected to the base 10 through the rotating shaft.

[0086] Reference Figure 3 The rotating shaft is constructed as a rotating body structure. Optionally, the rotating shaft has a step portion to facilitate the installation of the rotating bearing 13. Optionally, a bearing is provided between the first rotating shaft 22 and the first base 11, and between the second rotating shaft 23 and the second base 12. The stability and reliability of the rotation of the steering plate 21 are improved.

[0087] The steering plate 21 is configured as a plate-like structure. The steering plate 21 is rotatably connected to the base 10 around a first rotation axis AX1.

[0088] Reference Figure 1-Figure 5 , the steering plate 21 is connected with a first biasing member 24. The first biasing member 24 is connected to the steering plate 21 and the base 10, and / or the first biasing member 24 is connected to the steering plate 21 and the external structure. Optionally, the external structure is a shell. The two groups of first biasing members 24 are symmetrically arranged with the plane in which the first rotation axis AX1 and the first direction D1 are located as the symmetry plane. This allows the steering plate 21 to return to its initial position under the action of the biasing force of the symmetrical first biasing member 24, whether it rotates forward or reverse, and the force on the steering plate 21 is balanced at this time. Optionally, the first biasing member 24 adopts a spring. When the steering plate 21 is in the initial position, the first biasing member 24 is in a stretched state. Among them, when the steering plate 21 is in the initial position, the steering plate 21 is perpendicular to the first direction D1. Optionally, the central axis of the steering plate 21 is colinear with the first rotation axis AX1.

[0089] Reference Figure 2-Figure 4The steering plate 21 is provided with a connecting groove 25 which passes through along the first direction D1, and the second connecting member 30 is movably connected to the connecting groove 25 along the first direction D1. The second connecting member 30 can use the connecting groove 25 as a slide rail to move relative to the steering plate 21. By using the connecting groove 25 as a slide rail, the structural design of the entire device can be simplified, the number and complexity of parts can be reduced, the manufacturing cost can be reduced, and the assembly efficiency can be improved. As can be seen from the above, the steering plate 21 can rotate around the first rotation axis AX1, so the second connecting member 30 can rotate with the rotation of the steering plate 21. In this way, it is possible to better adapt to the posture and position changes of the mobile robot during charging and docking, thereby improving the accuracy and reliability of docking.

[0090] Optionally, the connection groove 25 is configured as a notch structure formed on the steering plate 21. This reduces manufacturing costs and improves assembly efficiency. In addition, it can also reduce friction and wear between components and extend the service life of the device.

[0091] Reference Figure 1 and Figure 3-Figure 6 The charging docking device further includes a steering baffle 40, which is spaced apart from the first connector 20 and is located on the rotation path of the first connector 20. The steering baffle 40 can limit the rotation of the steering plate 21. Optionally, the rotation angle of the steering plate 21 is 10°-15°.

[0092] Optionally, the steering baffle 40 is configured as a plate-like structure. The steering baffle 40 is fixed to the first base 11. When the steering plate 21 is in the initial position, the steering baffle 40 is parallel to the steering plate 21. Optionally, the steering baffle 40 is symmetrically arranged with the plane where the first rotation axis AX1 and the first direction D1 are located as the symmetry plane. Therefore, the forward rotation angle and the reverse rotation angle of the steering plate 21 are the same. Optionally, the forward rotation angle and the reverse rotation angle of the steering plate 21 can both be 10°-15°.

[0093] Optionally, the steering baffle 40 is provided with a through slot extending along the first direction D1 for the second connecting member 30 to pass through. That is, the second connecting member 30 passes through the through slot from one side of the steering baffle 40 and extends to the other side of the steering baffle 40. Therefore, when the steering plate 21 rotates, the second connecting member 30 rotates relative to the steering baffle 40. The opening size of the through slot is larger than the cross section of the portion of the second connecting member 30 located in the through slot, so that the smooth rotation of the second connecting member 30 can be ensured. Furthermore, the through slot can also serve as a rotation limiter for the second connecting member 30, so that the forward rotation angle and the reverse rotation angle of the steering plate 21 can both be 10°-15°.

[0094] The second connecting member 30 includes a first floating plate 31 and a first connecting rod 33. The first connecting rod 33 is connected to the first floating plate 31 and the first connecting member 20 respectively, and the first connecting rod 33 is slidably connected to the first connecting member 20, and the first connecting rod 33 extends along the first direction D1.

[0095] Based on the above embodiment, the connecting grooves 25 are symmetrically opened on both sides of the steering plate 21 with the plane where the first rotation axis AX1 and the first direction D1 are located as the symmetry plane. The through grooves are symmetrically opened in the middle of the steering baffle 40 with the plane where the first rotation axis AX1 and the first direction D1 are located as the symmetry plane.

[0096] The two groups of first connecting rods 33 are symmetrically connected to the two connecting grooves 25 with the plane where the first rotation axis AX1 and the first direction D1 are located as the symmetry plane. Optionally, each group of first connecting rods 33 is set to one or two. The connecting groove 25 is adapted to the shape of the connecting rod to limit the first connecting rod 33 from being separated from the connecting groove 25. The connecting groove 25 constitutes a limit for the upper and lower positions of the first connecting rod 33 along the first rotation axis AX1, thereby, the first connecting rod 33 can only translate along the first direction D1 relative to the steering plate 21, and will not be staggered with the connecting groove 25. Therefore, the second connecting member 30 can be stably connected to the first connecting member 20 and swing with the first connecting member 20.

[0097] Optionally, the first connecting rod 33 passes through the through slot of the steering baffle 40. The first connecting rod 33 can translate in the through slot along the first direction D1, and the first connecting rod 33 can swing around the first rotation axis AX1 in the through slot.

[0098] Optionally, the first connecting rod 33 passes through the connecting slot 25 of the steering plate 21. The first connecting rod 33 can translate in the connecting slot 25 along the first direction D1.

[0099] Optionally, the second connecting member 30 further includes a second floating plate 32. Figure 1-Figure 5 , the first connecting member 20 has a first side and a second side opposite to each other along the first direction D1. Specifically, the rotating plate has a first side and a second side opposite to each other along the first direction D1. The second floating plate 32 is located on the second side, and the first floating plate 31 is located on the first side. That is, the rotating plate is arranged between the first side and the second side. The first floating plate 31 and the second floating plate 32 are connected by a first connecting rod 33. Specifically, the first end of the first connecting rod 33 is located on the first side, the second end of the first connecting rod 33 is located on the second side, and the first end is connected to the first floating plate 31, and the second end is connected to the second floating plate 32. Through the arrangement of the second floating plate 32, the two ends of the first connecting rod 33 can be subjected to a relatively balanced force, further improving the stability of the device.

[0100] Optionally, the second floating plate 32 can be used as a mounting seat for mounting electronic components such as PCB boards, thereby adding more functions to the charging docking device, such as monitoring, control, communication, etc. This solution can fully utilize the structural space of the charging docking device itself, reasonably arrange the electronic components and movable components, and help improve the overall compactness and space utilization.

[0101] Optionally, the charging docking device further includes a second connecting rod 34 and a linear bearing 35. The second connecting rod 34 is connected to the first floating plate 31. The linear bearing 35 is connected to the rotating plate, and the second connecting rod 34 is slidably matched with the first connecting member 20 through the linear bearing 35. Optionally, the second connecting rod 34 is connected to the middle part of the steering plate 21, thereby further improving the stability of the connection between the first connecting member 20 and the second connecting member 30.

[0102] Optionally, the charging docking device further includes a second biasing member 36, which is connected between the first connector 20 and the second connector 30. Although the second biasing member 36 is shown as a spring, it is not limited to a spring. Specifically, the second biasing member 36 is arranged between the first floating plate 31 and the rotating plate. Under the action of an external force, the second biasing member 36 is stretched, thereby achieving the translation of the second connector 30 along the first direction D1. After the external force is removed, the second biasing member 36 returns to its original length and the second connector 30 is reset. Or the second biasing member 36 is arranged between the second floating plate 32 and the rotating plate. Under the action of an external force, the second biasing member 36 is compressed, thereby achieving the translation of the second connector 30 along the first direction D1. After the external force is removed, the second biasing member 36 returns to its original length and the second connector 30 is reset.

[0103] Optionally, the second biasing member 36 is sleeved on the second connecting rod 34. The second connecting rod 34 can provide a supporting force in the radial direction for the second biasing member 36, ensuring that the second biasing member 36 can only be extended or compressed in the axial direction.

During the movement of the second connecting member 30, it may collide with the first connecting member 20. The shock absorbing member 38 can absorb and reduce the collision between the second connecting member 30 and the first connecting member 20 during the movement, thereby protecting the connecting member from damage and extending the service life of the device.
