The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0032] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0033] In order to solve the problem of low utilization rate of charging sites in the charging process of new energy vehicles in the prior art, the utility model provides a socket fixed to the ground for charging with a mobile charging vehicle. Figure 1-4 As shown, the socket includes a plug board 1, a sliding cover 2, a positioning unit 3 and a guiding unit 4.

[0034] Specifically, the plug board 1 is provided with a socket 11 and a guide unit 4, and the mobile charging vehicle is usually provided with a transfer plug that is plugged into the socket 11. The transfer plug is plugged into the socket to provide power for the mobile charging vehicle. The mobile charging vehicle is also usually provided with a charging plug, which is used to charge new energy vehicles. It can be understood that the mobile charging vehicle plays the role of transferring power, and can be moved when not in use, thereby improving the utilization rate of the charging field.

[0035] The sliding cover 2 is usually slidably disposed on the plug board 1 , and a positioning unit 3 is disposed on the sliding cover 2 , and the positioning unit 3 is used to guide the mobile charging vehicle to be positioned at a first predetermined position.

[0036] Furthermore, the guiding unit 4 is used to guide the mobile charging vehicle to move from the first predetermined position to the second predetermined position. During the process of the mobile charging vehicle moving from the first predetermined position to the second predetermined position, the sliding cover 2 is driven to move in the direction from the first predetermined position to the second predetermined position so that the socket 11 is exposed outside the sliding cover 2.

[0037] In this way, the mobile charging vehicle is first positioned at the first predetermined position, and then moves to the second predetermined position under the action of the guiding unit. During this process, the sliding cover 2 is opened and the socket 11 is exposed outside the sliding cover 2, so that the socket can cooperate with the mobile charging vehicle for charging. After the mobile charging vehicle is moved away, the sliding cover 2 covers the socket, and the socket itself does not occupy a large volume, thereby improving the efficiency of the charging site.

[0038] In some embodiments, the socket fixed to the ground further includes a driving unit, and the driving unit is used to drive the sliding cover 2 to move in a direction from the first predetermined position to the second predetermined position.

[0039] Specifically, the driving unit may include a cylinder or a servo motor, and the cylinder or servo motor usually has a trigger relationship with the positioning unit 3 and the guiding unit 4. When the mobile charging vehicle is positioned at the positioning unit 3, the information of the positioning unit 3 can be read, thereby transmitting the signal to the driving unit, and the driving unit starts to move, so that the sliding cover 2 moves from the first predetermined position to the second predetermined position, so that the jack is exposed from the sliding cover; after the mobile charging vehicle is guided to the second predetermined position by the guiding unit 4, the mobile charging vehicle can read the signal of the guiding unit 4 and transmit the signal to the driving unit, and the driving unit can stop moving. This ensures that when the mobile charging vehicle reaches the second predetermined position, the jack 11 is exposed outside the sliding cover 2.

[0040] In this embodiment, reference Figure 2 , as shown in Figure 4, the positioning unit includes a positioning barcode; the guiding unit includes an RFID tag. The mobile charging vehicle is usually provided with a visual device capable of reading a barcode, and a navigation device capable of acquiring a radio frequency signal on the RFID tag. The mobile charging vehicle can be controlled to be positioned at the first predetermined position by the visual device, and the mobile charging vehicle can be controlled to be guided to the second predetermined position by the navigation device.

[0041] As a preferred embodiment, refer to Figure 2 As best shown, the outer surface of the slide cover 2 has a protruding abutment portion 21, and the abutment portion 21 can be abutted to enable the slide cover 2 to move from the first predetermined position to the second predetermined position.

[0042] It should be noted that when the mobile charging vehicle is used in conjunction with the mobile charging vehicle, when the mobile charging vehicle moves from the first predetermined position to the second predetermined position, the mobile charging vehicle has a force-applying part acting on the abutment part 21. Under the action of the force-applying part, the abutment part 21 can be abutted to make the slide cover 2 move in the direction from the first predetermined position to the second predetermined position. This arrangement can reduce the number of drive units and open the slide cover 2 through the mobile charging vehicle.

[0043] Furthermore, the slide cover 2 is provided with a guide rail 22 or a slide groove 12 matched with the guide rail along the direction from the first predetermined position to the second predetermined position, and the plug board 1 is provided with the slide groove 12 or the guide rail 22. With such a configuration, the slide cover 2 can slide relatively smoothly relative to the plug board 1, thereby extending the service life of the slide cover 2.

[0044] Specifically, in this embodiment, two guide rails 22 are provided on the sliding cover 2 along the direction from the first predetermined position to the second predetermined position, and the two side walls of the plug board 1 parallel to the direction from the first predetermined position to the second predetermined position are provided with the slide grooves 12. Each guide rail 22 is slidably disposed in the corresponding slide groove 12.

[0045] Furthermore, the socket fixed to the ground further includes a reset component, which is connected between the plug board 1 and the slide cover 2 and is used to make the slide cover 2 cover the socket 11 when the slide cover 2 is not abutted. The reset component here plays the role of making the slide cover 2 cover the socket 11 when the mobile charging vehicle is not matched with the socket to prevent foreign objects from entering, thereby playing a role of safety protection.

[0046] Specifically, refer to Figure 4 As shown, the reset assembly includes at least one spring 5, and a receiving groove 13 for receiving the spring 5 is provided on the plug board 1 along the direction from the first predetermined position to the second predetermined position. The spring 5 is provided along the direction from the first predetermined position to the second predetermined position, and one end of the spring 5 is connected to the bottom of the receiving groove 13, and the other end is connected to the slide cover 2. Generally speaking, when the slide cover 2 is provided on the plug board 1 to cover the insertion hole 11, the spring 5 is in a free state without elastic deformation, and when the slide cover 2 is abutted and moves along the direction from the first predetermined position to the second predetermined position, the spring 5 is elastically deformed, and when the abutting force is cancelled, the elasticity of the spring 5 can drive the slide cover 2 connected thereto to return to motion, thereby covering the insertion hole 11.

[0047] Furthermore, the slide cover 2 includes a slide cover body 23 and a fixing column 24 disposed inside the slide cover body, the abutment portion 21 is located on the outer surface of the slide cover body 23, and one end of the spring 5 away from the groove bottom is connected to the fixing column 24. Such a configuration can reduce the spring 5 to be better connected to the slide cover 2, and avoid friction with the groove side wall of the accommodating groove 13 when it undergoes elastic deformation.

[0048] In this embodiment, the notch of the receiving slot 13 is located on the first side of the plug board 1, and the socket fixed to the ground further includes a magnetic unit, which includes a first magnet 61 and a second magnet 62 matched with the first magnet, the first magnet 61 is arranged on the first side, and the second magnet 62 is arranged on the slide cover 2. When the slide cover 2 covers the plug hole 11, the first magnet 61 and the second magnet 62 are attracted and contacted. Thus, the slide cover 2 can stably cover the plug hole 11 to avoid movement.

[0049] Generally speaking, the sliding cover 2 is provided with a mounting portion 25 for mounting the second magnet 62. The mounting portion 25 can be configured as a flange or a reinforcing rib extending toward the plug plate, and the second magnet 62 is mounted on the side of the flange or the reinforcing rib facing the first side. This ensures that the first magnet 61 and the second magnet 62 are well matched. When the sliding cover 2 covers the plug hole 11, the mounting portion 25 is located relative to the first side, and the first magnet 61 and the second magnet 62 are located between the first side and the mounting portion 25, further ensuring that the sliding cover 2 can stably cover the plug hole 11 to avoid movement.

[0050] In this embodiment, the plug board 1 is generally further provided with a connecting member 14 . The connecting member 14 is disposed on a second side of the plug board 1 facing away from the first side, and the guiding unit 4 is mounted on the connecting member 14 .

[0051] Specifically, the mounting portion 14 includes a first connecting plate and a second connecting plate intersecting at a certain angle, and preferably, the angle between the first connecting plate and the second connecting plate is 90°. That is, the first connecting plate and the second connecting plate are perpendicular to each other, the second connecting plate is connected to the second side, and the side of the second connecting plate away from the first connecting plate protrudes out of the upper surface of the plug board 1, thereby limiting the sliding cover 2 slidably arranged on the plug board 1, and the guiding unit 4 is located in the space surrounded by the first connecting plate and the second connecting plate.

[0052] An embodiment of the utility model also provides a charging system for new energy vehicles, which includes a mobile charging vehicle and a socket fixed to the ground as described above, wherein the mobile charging vehicle includes a charging plug, a switching plug, a positioning identification unit, a guiding identification unit and a lifting unit.

[0053] The positioning identification unit is used to cooperate with the positioning unit to control the mobile charging vehicle to be positioned at the first predetermined position. The positioning unit is usually a positioning barcode, and the positioning identification unit can usually be a visual monitoring device for monitoring the positioning unit and guiding the movement of the mobile charging vehicle.

[0054] The guide identification unit cooperates with the guide unit to control the mobile charging vehicle to move from the first predetermined position to the second predetermined position. The guide unit can generally be an RFID radio frequency tag, and the guide identification unit can be a reader that can identify the radio frequency signal on the RFID radio frequency tag. Multiple readers cooperate with each other to guide the vehicle to move from the first predetermined position to the second predetermined position.

[0055] The lifting unit is used to drive the adapter plug to move and plug it into the socket when the mobile charging vehicle is located at the second predetermined position.
