Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a base docking mechanism of a robot. Background Art

[0002] Mobile robots are being used more and more widely in various occasions, such as entertainment, handling, cleaning, security, etc. These include automatic walking robots, vehicles traveling along tracks, remote-controlled vehicles, manned and autonomous vehicles, etc.

[0003] At present, the automatic charging solutions for mobile robots mainly include rail type and non-rail type. The rail type solution guides the mobile robot to complete contact charging by setting rails, while the non-rail type solution mainly uses electromagnets to provide adsorption force to guide the mobile robot to complete contact charging.

[0004] Therefore, it is necessary to use a robot base docking mechanism to charge the robot.

[0005] For example, the prior art Chinese patent publication number "CN115832772 A" provides a steerable charging base and a robot charging system, wherein the charging base comprises: a base body, a base base and a rotating mechanism; wherein a magnetic power supply end is provided on the base body, the magnetic power supply end comprises a power supply terminal and a first magnet, and the rotating mechanism is used to drive the base body to rotate relative to the base base when the first magnet is magnetically attracted, so that the magnetic power supply end can dock with the magnetic charging end to be docked.

[0006] The device enables the base body to be steered relative to the base base. The charging base assists the mobile robot in successfully recharging and docking by being steerable as a whole. The magnetic power supply end can dock with the magnetic charging end more accurately, effectively improving the recharging and docking success rate between the mobile robot and the charging base, and simplifying the position adjustment steps required for recharging the mobile robot.

[0007] With the existing robot base docking mechanism, during the process of the robot docking with the charging structure, the robot base will generate impact and collision when it moves to contact the charging structure, which is likely to cause damage from the collision, leading to malfunction and damage to the base or the charging structure. A buffer structure is not provided to buffer, reduce shock and resist impact for the docking between the base and the charging structure. Moreover, after the base and the charging structure are docked and inserted, they are prone to loosening and power failure. A tightening and clamping structure is not provided inside the docking structure to tighten and clamp the docking connection between the base and the charging structure. Utility Model Content

[0008] The purpose of the utility model is to solve the shortcomings in the prior art that when the base of the robot moves to contact with the charging structure, impact and collision will occur, which is easy to cause collision damage, resulting in malfunction and damage to the base or the charging structure, and no buffer structure is provided to buffer, reduce shock and resist impact during the docking between the base and the charging structure, and a base docking mechanism for the robot is proposed.

[0012] Furthermore, the mounting sleeve is a circular cylinder structure, and is slidably and rotatably connected to the base via the dust ring. The dust ring is made of elastic rubber material, has a circular ring structure, and is horizontally arranged at the upper and lower ends of the docking groove.

[0013] Furthermore, the rotating plate is a circular ring structure and is horizontally slidably arranged on the top of the base. The first connecting hole is a threaded hole structure, and the bolt is threadedly connected to the first connecting hole.

[0014] Furthermore, the bolt is vertically arranged and slides through the rotation groove, the rotation groove is an arc-shaped groove structure, and the plug-in groove is aligned with the docking groove.
