[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] like Figure 1 As shown, a circuit docking device includes a horizontally arranged mobile platform 1, a plug 2 and a socket 3; the socket 3 is fixed on a horizontal plane, the plug 2 is fixed on the mobile platform 1 and can move in the plane where the mobile platform 1 is located, and the plug 2 can also be inserted into the socket 3 along a plane perpendicular to the mobile platform 1. When the plug is fully inserted into the socket, the circuit can be connected.

[0026] The mobile platform 1 is connected to the plug 2 via a spring 4, so that a certain deviation is allowed when the plug 2 and the socket 3 are matched. Figure 2 , one end of the spring 4 is fixed to the center of the upper end of the plug 2, and the other end is fixed to a slider 11. The slider 11 is movably arranged on a slide bar 12. The slide bar 12 can slide on the mobile platform 1 in a direction perpendicular to its own length, so that the plug 2 is controlled to move in the plane where the mobile platform 1 is located through the cooperation of the slider 11 and the slide bar 12. The wire in the plug 2 passes through the middle of the spring 4 and is connected to the circuit. Specifically, an electric sheet (not shown) can be arranged on the slider 11 and the slide bar 12, and conduction is achieved through the contact of the electric sheet. Alternatively, the wire extending from the spring 4 can be directly connected to the spring wire (not shown). When the slider 11 moves, the spring wire automatically expands and contracts according to the position, thereby avoiding affecting the movement of the slider 11.

[0027] Refer to Figure 1 In the preferred embodiment, the plug 2 is a conical structure, which simply faces the socket 3. The shape of the socket 3 is the same as that of the plug 2, so that the plug 2 and the socket 3 are easy to match. The side of the plug 2 is provided with a first electrode 21 representing the positive and negative electrodes respectively, and two second electrodes 31 are provided at corresponding heights in the socket 3. After the plug 2 enters the socket 3, the first electrode 21 contacts the second electrode 31 to connect the circuit. Since the plug 2 needs to change its position on the mobile platform 1, in order to ensure that the first electrode 21 and the second electrode 31 can contact, two circles of electric sheets are respectively provided on the plug 2 at different heights as the first motor 21, and the second electrode 31 is provided on the side of the socket 3 and protrudes to one side of the plug 2, so as to ensure that the first electrode 21 and the second electrode 31 can maintain a good contact state. Of course, the first electrode 21 can also be set as a point electrode, the second electrode 31 can be set as a circle of electric sheets, or the first electrode 21 and the second electrode 31 can both be set as a circle of electric sheets.

[0028] The socket 3 is also provided with a cover plate 32. When the circuit is disconnected, the cover plate 32 closes the socket 3. When docking, the cover plate 32 moves in the horizontal direction to expose the socket 3. After the plug 2 and the socket 3 are mated, the cover plate 32 can move in the horizontal direction to press the plug 2, thereby ensuring that the circuit remains connected during use.

[0029] In a preferred embodiment, the upper end of the plug 2 naturally contracts inwards, so that the cover plate 32 can naturally press the top of the plug 2 during the movement.

[0030] Combination Figure 3 A positioning unit 5 is also provided at the end of the plug. The positioning unit 5 is assembled to be able to identify the position of the socket 3 to adjust the position of the plug 2 along the horizontal plane, and when the plug 2 is inserted into the plug port 3, it identifies and determines whether the plug 2 is in place, and after the plug 2 is in place, the cover plate 2 is reset.

[0031] Specifically, the positioning unit 5 includes a platform 51 fixed to the end of the plug 2 and a camera 52 arranged on the platform 51. The camera 52 can rotate the viewing angle on the platform. In a preferred embodiment, a transparent cover 53 for protecting the lens is also arranged outside the camera 52. The positioning unit 5 determines the position of the socket 3 through image recognition and performs positioning. The camera 52 can be a common surveillance camera or a similar product. A person skilled in the art can also use other methods such as infrared rays for positioning based on this embodiment.

[0032] The circuit docking device also includes a feedback unit (not shown) for determining whether the plug is in place. When the feedback unit determines that the plug is in place, it can issue a command to control the cover plate 32 to restrict the plug 2 in the socket 3 to ensure that the circuit maintains a good connection during use. Figure 1 , the feedback unit includes at least one identification block 33 disposed on the side below the socket 3, the identification block 33 is blocked by the side wall of the socket 3, when the plug 2 and the socket 3 are matched, the camera 52 goes deep into the bottom of the socket 3, and the camera 52 with a substantially horizontal viewing angle can obtain the image of the identification block 33 to determine that the plug 2 is inserted in place. In a preferred embodiment, a circle of annular identification blocks 33 are disposed at the bottom of the socket 3, and the identification blocks 33 are provided with a color different from the surrounding environment, and the camera 52 confirms whether the plug 2 is in place by color comparison.

[0033] refer to Figure 4 Another embodiment of the feedback unit provided by the present invention comprises a protrusion 61 fixed on the side of the plug 2 and a block 62 arranged at the bottom of the socket 3 and matched with the protrusion 61. The block 62 is axially fixed on a positioning pin 63, and a positioning spring 64 is sleeved on the positioning pin 63. A contact piece 65 is provided on the side of the block 62 away from the plug 2. In the natural state, the block 62 is separated from the contact piece 65. When the plug 2 is inserted into the socket 3 and the matching is completed, the protrusion 61 contacts the block 62 to press the block 62 along the positioning pin 63 toward the contact piece 65. When the block 62 contacts the contact piece 65, the judgment circuit of the feedback unit is connected, and the cover plate 32 moves to restrict the plug 2 in the socket 3. In the preferred embodiment, the block 61 is provided with a circle along the side of the plug 2. When the plug 2 leaves the socket 3, a command is first issued to make the cover plate 32 move to leave the plug 2, and then the plug 2 is taken out of the socket 3.

[0034] refer to Figure 5 This embodiment also provides a charging pile with the circuit docking device, including a vertically fixed pile body 6, a mobile platform 1 fixedly matched with the pile body 6 in a vertical direction and in a horizontal state, and a socket 3 fixed above the walking device; a plug 2 matching with the socket 3 is provided on the mobile platform 1.

[0035] The walking device can be an electric car, an electric bicycle, an electric robot or other electrical equipment. Taking an electric car as an example, the pile body 6 is fixed next to the parking space. After the electric car is parked in the parking space, the socket 3 is exposed by opening the cover 32. The positioning unit 5 moves the plug 2 along the mobile platform 1 to above the socket 3 through identification and positioning. Then the mobile platform 1 moves along the pile body 6 to insert the plug 2 into the socket 3 in a vertical direction. When the positioning unit 5 identifies the identification block 33, the cover 32 moves to fix the plug 2 in the socket 3, the circuit is connected, and the electric car starts to charge.

[0036] A cover plate 32 is provided on each side of the socket 2. When not charging, the cover plates 32 on both sides are completely in contact to close the socket; when charging, a gap is left between the cover plates 32 on both sides to allow the spring 4 to pass. When the camera 52 and the identification block 33 are used as feedback units, since the image information obtained by the camera 52 is recognized in the system of the charging pile itself, the action of the cover plate 32 cannot be directly controlled. Therefore, after the camera 52 obtains the information of the identification block 33, it first acts to connect the circuits of the plug 2 and the socket 3, and then the socket 3 or the independent control system in the walking device issues a command to close the cover plate 32.

[0037] Of course, the pile body 6 can also be arranged on another walking device, so that charging can be completed while the walking device is running.

[0038] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Without departing from the spirit and principles of the present invention, any modifications, equivalent substitutions, improvements, etc. made to the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
