[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0025] like Figure 1 and Figure 2 As shown, in one embodiment, a docking structure 10 is provided, comprising a first docking member 100, a second docking member 200, a mounting body 300 and an elastic mounting member 400. The elastic mounting member 400 is used to mount the first docking member 100 on the mounting body 300. When the second docking member 200 moves to a docking position relative to the mounting body 300, the second docking member 200 is electrically connected to the first docking member 100 and pushes the first docking member 100, so that the elastic mounting member 400 is elastically deformed to apply a pressure to the first docking member 100 along a pressing direction (such as Figure 2 When the second docking member 200 moves out of the docking position relative to the mounting body 300, the electrical connection between the second docking member 200 and the first docking member 100 is released, and the elastic mounting member 400 drives the first docking member 100 to reset.

[0026] When the docking structure 10 in the above embodiment is used, the mounting body 300 is mounted in the battery compartment of the machine body, so that when a rechargeable battery is installed in the battery compartment, the first docking member 100 on the mounting body 300 is electrically connected to the rechargeable battery. The second docking member 200 is mounted on the battery compartment cover 20 accordingly, and is electrically connected to the charging electrode 30 on the battery compartment cover 20. When the battery compartment cover 20 is covered in the battery compartment, the second docking member 200 is electrically connected to the first docking member 100, and pushes the first docking member 100, so that the elastic mounting member 400 is elastically deformed to apply docking pressure along the pressing direction to the first docking member 100, ensuring that the first docking member 100 and the second docking member 200 can maintain electrical connection, so as to achieve stable and reliable charging of the rechargeable battery. When the battery compartment cover 20 is removed from the machine body to open the battery compartment, the electrical connection between the second docking member 200 and the first docking member 100 is released, and the elastic restoring force of the elastic mounting member 400 drives the first docking member 100 to reset, so that when the battery compartment cover 20 is again covered on the battery compartment, a docking pressure along the pressing direction can be applied to the first docking member 100, thereby improving the reliability of the docking structure 10. The docking structure 10 in the present application can ensure the stability and reliability of the electrical connection between the charging electrode 30 and the rechargeable battery without changing the detachable connection structure between the battery compartment cover 20 and the machine body, thereby realizing the robot's compatibility with the requirements of quick battery replacement and charging with a charging pile.

[0027] It should be noted that the present application is described in detail by taking the installation body 300 installed in the battery compartment and the second docking member 200 installed on the battery compartment cover 20 as an example. In other embodiments, the installation body 300 can also be installed on the battery compartment cover 20, and the second docking member 200 is correspondingly installed in the battery compartment. The principle is the same or similar to the above, and will not be described in detail here.

[0028] The present application is described by taking the application of the docking structure 10 on a robot as an example, which should not be construed as limiting the present application. In other embodiments, the docking structure 10 can also be applied to occasions or devices that require both detachable and electrical connection.

[0029] The docking position refers to the position of the second docking member 200 relative to the mounting body 300 when the battery compartment cover 20 is covered in the battery compartment. The pressing direction refers to the direction from the first docking member 100 to the second docking member 200 when the battery compartment cover 20 is covered in the battery compartment and the second docking member 200 is electrically connected to the first docking member 100.

In this way, the inner side wall of the mounting through hole can guide the first docking portion 120, so as to ensure that the second docking member 200 can push the first docking member 100 in the opposite direction of the pressing direction, thereby ensuring that the first docking member 100 squeezes the elastic mounting member 400 to cause elastic deformation. After elastic deformation, the elastic mounting member 400 applies docking pressure along the pressing direction to the first docking member 100, so as to achieve stable and reliable electrical connection between the first docking member 100 and the second docking member 200, thereby improving the reliability of the docking structure 10.

In this way, the extension length of the mounting through hole is increased, so that the contact area between the inner side wall of the mounting through hole and the first docking portion 120 is increased, ensuring that the inner side wall of the mounting through hole can guide the first docking member 100, thereby improving the reliability and stability of the docking structure 10.

[0036] Please continue reading Figure 2 Optionally, a side of the mounting body 300 having the mounting groove 310 is set as a mounting side 330, and a side of the mounting body 300 adjacent to the mounting side 330 is provided with an opening 340, the opening 340 is communicated with the mounting groove 310, and extends to the mounting side 330. In this way, the opening 340 can be used for threading, so as to electrically connect the first docking member 100 with the rechargeable battery.

[0037] Please continue reading Figure 2 In a preferred embodiment, the second docking member 200 protrudes toward a side close to the first docking portion 120 to form a second docking portion 210, and the second docking portion 210 is used to be electrically connected to the first docking portion 120 and is in surface contact. In this way, the docking area between the first docking member 100 and the second docking member 200 is increased, thereby improving the reliability of the docking structure 10.

[0038] Specifically in this embodiment, the first docking portion 120 and the second docking portion 210 are arranged in parallel on one side thereof and perpendicular to the pressing direction on the other side thereof.

[0039] like Figure 2 As shown, further, the second docking member 200 includes two second mounting portions 220, and the two second mounting portions 220 are respectively located on two opposite sides of the second docking portion 210. In this way, by increasing the number of the second mounting portions 220, the connection strength between the second docking member 200 and the battery compartment cover 20 is increased, thereby improving the reliability of the docking structure 10.

[0040] The second mounting portion 220 can be mounted on the battery compartment cover 20 by screwing, plugging, clamping, welding, riveting or other connection methods. The mounting body 300 can be mounted on the inner wall of the battery compartment by screwing, plugging, clamping, welding, riveting or other connection methods.

The mounting body 300 is also provided with at least one third mounting portion 350, and each third mounting portion 350 is mounted on the inner wall of the battery compartment by screwing.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, a robot (not shown) is provided, including a machine body, a battery compartment cover 20, a charging electrode 30 and a docking structure 10 in any of the above embodiments.

The second docking member 200 is mounted on the battery compartment cover 20 accordingly, and is electrically connected to the charging electrode 30 on the battery compartment cover 20. When the battery compartment cover 20 is covered in the battery compartment, the second docking member 200 is electrically connected to the first docking member 100, and pushes the first docking member 100, so that the elastic mounting member 400 is elastically deformed to apply docking pressure along the pressing direction to the first docking member 100, ensuring that the first docking member 100 and the second docking member 200 can maintain electrical connection, and realizing stable and reliable charging of the rechargeable battery by the charging pile. When the battery compartment cover 20 is removed from the machine body to open the battery compartment, the electrical connection between the second docking member 200 and the first docking member 100 is released, and the elastic mounting member 400 drives the first docking member 100 to reset, so that when the battery compartment cover 20 is again covered on the battery compartment, a docking pressure along the pressing direction can be applied to the first docking member 100, thereby improving the reliability of the docking structure 10. The docking structure 10 in the present application can ensure the stability and reliability of the electrical connection between the charging electrode 30 and the rechargeable battery without changing the detachable connection structure between the battery compartment cover 20 and the machine body, thereby realizing the robot's compatibility with the requirements of quick-release battery replacement and charging with a charging pile.
