[0045] Example 1

[0046] Refer to Figure 1As shown in the figure, this embodiment provides a self-leveling brush device, including a first brush 1 and a second brush 2. The first brush 1 includes a first base 11 and a first electrode 12. The first base 11 includes a first body 111, a second body 112, and an elastic member 113. The first body 111 is movably connected to the second body 112 in the vertical direction, and the elastic member 113 is connected between the first body 111 and the second body 112, having an elastic force that drives the first body 111 to move away from the second body 112. The first electrode 12 is installed on the first base 11. When the first base 11 moves relative to the second base 21, the height of the first electrode 12 can be changed. The elastic member 113 provides an elastic force for the first body 111, so that the first body 111 has a tendency to move upward. In this embodiment, the elastic member 113 is a spring. In other embodiments, other structures that can undergo elastic deformation can also be selected to provide an elastic force for the first electrode 12 within a certain stroke. The first electrode 12 includes a first contact surface 121, and this contact surface is used to dock with the electrode in another brush, thereby forming a charging circuit.

[0047] The second brush 2 includes a second base 21 and a second electrode 22; the second electrode 22 includes a second contact surface 221, and the second contact surface 221 is used to dock with the first contact surface 121 to form a charging circuit. The second electrode 22 is located above the first electrode 12, and the second electrode 22 is movably installed on the first base 11, so that when the first brush 1 and the second brush 2 are docked, the first contact surface 121 and the second contact surface 221 are automatically leveled and fitted. When the automated operation device 4 moves to the position of the charging pile 3 and the two brushes are docked, the first contact surface 121 contacts the second contact surface 221, and the elastic member 113 provides an elastic force to press the first contact surface 121 against the second contact surface 221. Since the second electrode 22 is movably installed on the first base 11, the first electrode 12 and the second electrode 22 are automatically leveled to form a surface contact under the action of the pressing force, and the reliability of the contact between the first contact surface 121 and the second contact surface 221 is improved by the elastic force of the elastic member 113.

[0048] A self-leveling brush device provided by this embodiment can automatically level the electrodes relative to each other when the two brushes are docked, ensuring a surface contact between the two electrodes, improving the conduction efficiency, and reducing the requirements for installation.

[0049] Specifically, referring to Figures 2 to 5As shown, the first electrode 12 is hinged to the first base 11 so as to rotate about the first axis direction, and the second electrode 22 is hinged to the second base 21 so as to rotate about the second axis direction, and the first axis is perpendicular to the second axis, and both the first axis and the second axis are perpendicular to the vertical direction. When the first brush 1 is docked with the second brush 2, the first electrode 12 rotates about the first axis direction and the second electrode 22 rotates about the second axis direction, so that the first contact surface 121 and the second contact surface 221 are automatically leveled under the action of the elastic member 113.

[0050] Specifically, the first brush 1 further includes a first hinge shaft 13, and the first hinge shaft 13 penetrates through the first electrode 12 along the middle position of the first electrode 12, so that the first electrode 12 is hinged to the first base 11 through the first hinge shaft 13. The second brush 2 further includes a second hinge shaft 23, and the second hinge shaft 23 penetrates through the second electrode 22 along the middle position of the second electrode 22; so that the second electrode 22 is hinged to the second base 21 through the second hinge shaft 23. In this embodiment, the electrodes and the bases are connected by means of hinge shafts, and in other embodiments, other hinge forms can also be used to connect the electrodes and the bases.

[0051] Since the first hinge shaft 13 penetrates through the first electrode 12 along the middle position of the first electrode 12, both ends of the first electrode 12 can rotate about the axis of the first hinge shaft 13, so as to be automatically leveled during docking. By providing two first limit blocks 114 on the first base 11, and the two first limit blocks 114 are respectively located on both sides of the first hinge shaft 13, when the first electrode 12 rotates, the two first limit blocks 114 limit both ends of the first electrode 12, so as to limit the rotation angle of the first electrode 12.

[0052] Since the second hinge shaft 23 penetrates through the second electrode 22 along the middle position of the second electrode 22, both ends of the second electrode 22 can rotate about the axis of the second hinge shaft 23, so as to be automatically leveled during docking. By providing two second limit blocks 211 on the second base 21, and the two second limit blocks 211 are respectively located on both sides of the second hinge shaft 23, when the second electrode 22 rotates, the two second limit blocks 211 limit both ends of the second electrode 22, so as to limit the rotation angle of the second electrode 22.

[0053] Specifically, there are at least two docking methods for the first brush 1 and the second brush 2. One is the up-and-down positive docking method, and the other is the side-cutting method. Refer to Figure 6 As shown, in the up-and-down positive docking method, the automated operation device 4 moves to a position where the first brush 1 is below the second brush 2 and forms a certain distance, and drives the first brush 1 to move vertically so that the first contact surface 121 contacts the second contact surface 221 and is automatically leveled. Refer to Figure 7As shown in the figure, in the lateral cutting-in type, the automated operating device 4 moves to the side of the first brush 1 relative to the second brush 2 and drives the first brush 1 to move horizontally, so that the first contact surface 121 contacts the second contact surface 221 and is automatically leveled. In the lateral cutting-in type, guiding inclined surfaces can be respectively arranged on the end faces of the first motor and the second electrode 22, so that the first contact surface 121 is slightly higher than the second contact surface 221 before docking. With the lateral movement of the first electrode 12, under the action of the guiding inclined surface, the first contact surface 121 moves below the second contact surface 221 and fits with it.

[0054] Specifically, referring to Figure 5 As shown in the figure, the first base 111 includes a guiding sleeve 115 and a guiding shaft 116, and a guiding space is formed between the guiding sleeve 115 and the guiding shaft 116; the second base 112 includes a fixing sleeve 117, and the fixing sleeve 117 is inserted into the guiding space movably relative to the guiding sleeve 115. The mutual cooperation between the guiding sleeve 115 and the fixing sleeve 117 forms a guiding structure for vertical movement, ensuring that the first electrode 12 moves vertically during the docking process.

[0055] Specifically, the first base 11 includes a first installation space, and a part of the first electrode 12 is located inside the first installation space and a part is located outside the first installation space, so that the first contact surface 121 is exposed outside the first installation space; the second base 21 includes a second installation space, and a part of the second electrode 22 is located inside the second installation space and a part is located outside the second installation space, so that the second contact surface 221 is exposed outside the second installation space. Exposing the first contact surface 121 outside the first installation space and the second contact surface 221 outside the second installation space facilitates the contact and leveling of the first contact surface 121 and the second contact surface 221 when the first brush 1 is docked with the second brush 2.

[0056] Embodiment 2

[0057] Referring to Figure 8 As shown in the figure, the present embodiment provides a self-leveling brush device, which is different from the self-leveling brush device provided in Embodiment 1 in that the connection manner between the first electrode 12 and the first base 11 is different, and the connection manner between the second electrode 22 and the second base 21 is different. The following describes the differences, and the same parts will not be elaborated in this embodiment.

[0058] Referring to Figures 9 to 12As shown, in this embodiment, the first electrode 12 is fixedly installed on the first base 11. The second electrode 22 is installed on the second base 21 through a ball joint, forming a spherical pair between the second electrode 22 and the second base 21. When the first brush 1 is docked with the second brush 2, the angle of the first contact surface 121 on the first electrode 12 remains unchanged. Under the pressing force provided by the elastic member 113, the second contact surface 221 on the second electrode 22 automatically corrects along with the first contact surface 121, so that the first contact surface 121 fits with the second contact surface 221.

[0059] Specifically, a boss 212 is provided in the middle of the second base 21, and a rotation space is formed between the periphery of the boss 212 and the second base 21. The ball joint includes a small ball 24, and the small ball 24 is respectively connected to the boss 212 and the second electrode 22 to form a spherical pair. The rotation space provides a certain space for the rotation of the second electrode 22. Limiting plates 213 are also provided around the second base 21, and a flange 222 is provided at the top of the second electrode 22. The limiting plates 213 are located below the flange 222 to limit the rotation angle of the flange 222. When the second electrode 22 rotates until the flange 222 abuts against the limiting plates 213, the rotation of the second electrode 22 is restricted.

[0060] Specifically, the connection method between the small ball 24 and the boss 212 and the second electrode 22 can be such that the small ball 24 is fixedly connected to the boss 212, and a spherical groove with a depth greater than the radius of the small ball 24 is provided at the top of the second electrode 22, so that the small ball 24 is in sliding fit with the spherical groove, thereby forming a ball joint structure between the second electrode 22 and the second base 21. In other embodiments, other structural forms can also be used to realize the connection between the second electrode 22 and the second base 21.

[0061] In this embodiment, the first brush 1 is installed on the automatic operation device 4, and the second brush 2 is installed on the charging pile 3. In other embodiments, the first brush 1 can also be installed on the charging pile 3, and the second brush 2 can be installed on the automatic operation device 4.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
