[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0026] Example 1

[0027] As one embodiment of this utility model, this embodiment provides a floating charging device. For example... Figure 1 As shown, the floating charging device includes a charger 1, a flexible support 2, and a charging plug 3. The charger 1 is fixed to the ground or a wall. One end of the flexible support 2 is fixed to the charger 1, and the charging plug 3 is installed at the other end of the flexible support 2. The charging plug 3 and the charger 1 are electrically connected via a flexible cable, providing a charging interface for the robot 5. A charging socket 4 matching the charging plug 3 is provided on the robot 5. The charging operation of the charger 1 for the robot 5 is completed by matching the charging plug 3 with the charging socket 4. This utility model, by setting the flexible support 2, allows the charging plug 3 to float horizontally when plugged in, and has the advantages of simple structure, convenient installation, and low cost.

[0028] like Figure 2 As shown, in this embodiment, the flexible support 2 includes a base 21, two elastic arms 22, and a floating mounting plate 23. The base 21 is the fixing part of the entire flexible support 2, used to install and fix the flexible support 2 on the charger 1 to provide stable support. Figure 2 As shown, in this embodiment, the base 21 is provided with multiple fixing holes. The flexible bracket 2 can be detachably installed on the output end of the charger 1 by bolts or other fixing methods to prevent the flexible bracket 2 from moving or sliding between itself and the charger 1 during use. The elastic arm 22 is an arm extending from the base 21, made of elastic material and having a certain bending and stretching capacity, allowing the elastic arm to move freely within a certain range while maintaining its connection with the base to ensure the overall stability of the bracket. The floating mounting plate 23 is installed at the end of the elastic arm 22 and can be designed with a specific shape and structure to adapt to different charging plug 3 installation requirements. Figure 2 As shown, the floating mounting plate 23 is provided with a plurality of mounting holes for fixing the charging plug 3, and the floating mounting plate 23 is also provided with a plug groove for accommodating the flexible cable to pass through.

[0029] Furthermore, the elastic arm 22 adopts a double-fold structure, including a first connecting part 221 and a second connecting part 222 connected to each other. One end of the first connecting part 221 is connected to the base 21, and the outer surface of the first connecting part 221 forms an obtuse angle with the outer surface of the base 21. The other end of the first connecting part 221 is connected to the second connecting part 222, and the angle between the outer surfaces of the first connecting part 221 and the second connecting part 222 is less than 180°. The other end of the second connecting part 222 is connected to the floating mounting plate 23, and the inner surface of the second connecting part 222 forms an acute angle with the inner surface of the floating mounting plate 23. The floating mounting plate 23, the two elastic arms 22, and the base 21 form a concave "U"-shaped flexible support 2, which allows the support to move horizontally when subjected to force. At the same time, the inwardly folded elastic arms 22 on both sides can absorb and disperse the vertical external force generated when the charging plug 3 is connected, reducing the impact on the charger 1.

[0030] In this embodiment, the base 21, the elastic arm 22, and the floating mounting plate 23 are integrally formed, and the connections between the base 21 and the elastic arm 22, the elastic arm 22 and the floating mounting plate 23, and the first connecting portion 221 and the second connecting portion 222 of the elastic arm 22 are all provided with arc-shaped chamfers. When the flexible support 2 is subjected to force, it can mitigate the impact of the interaction force on the connection between the components.

[0031] As an alternative, the portion connecting the elastic arm 22 to the base 21 can also be connected using a hinge or other connection mechanism. A torsion spring can be used to connect the first connecting portion 221 and the second connecting portion 222 of the elastic arm 22, allowing the elastic arm 22 to return to its initial state after docking.

[0032] When the robot 5 and the charging plug 3 are connected and matched, there will always be a certain error in their positions. The floating charging device proposed in this utility model uses the flexible bracket 2 to perform horizontal elastic deformation so that the horizontal position of the charging plug 3 can be floated and finely adjusted. In addition, the flexible bracket 2 can absorb and disperse the external force perpendicular to the charger 1, avoid damage to the structure of the charger 1, and improve the overall stability and durability of the charging device.

[0033] Example 2

[0034] As another embodiment of this utility model, this embodiment also provides a robot charging system, such as... Figure 3 As shown, the robot charging system includes a floating charging device as described in Embodiment 1 above and a robot 5 equipped with a charging socket 4.

[0035] Robot 5 can move autonomously to achieve approximate alignment with charger 1. The charging socket 4 has a guide structure to facilitate connection with the charging plug 3.

[0036] The working principle of this robot charging system is as follows: When robot 5 autonomously approaches charger 1, it automatically aligns with the charger. Due to various reasons causing errors, the charging plug 3 and charging socket 4 cannot be perfectly aligned. Figure 4 As shown, the charging socket 4 is designed with a flared guide device. When the robot 5 moves linearly toward the charger 1, the guide device on the charging socket 4 will constrain the charging plug 3, and because the charging plug 3 is installed as shown... Figure 4 On the flexible support 2, it can float horizontally within a certain range. The constrained charging plug 3 will gradually align with the charging socket 4 and finally complete the insertion action to complete the connection required for charging.

[0037] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
