Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging, and in particular to a mobile charging robot and an emergency charging method. Background Art

[0002] Mobile charging robots are different from conventional charging piles. They can be moved to the side of a vehicle to charge the vehicle, and can be used in emergency situations such as when the vehicle cannot be moved. Mobile charging robots generally include a movable body that can store energy, and a charging gun on one side of the body. Existing mobile robots will fix a hook on one side of the body. When charging is not needed, the cable of the charging gun is wrapped around the hook, and finally the charging gun is plugged into the socket of the body; when charging is needed, the cable will be removed from the hook, and then the charging gun will be plugged into the charging port of the vehicle.

[0003] When an existing mobile charging robot is parked next to a vehicle to be charged, the surrounding environment may cause the charging robot to be far or close to the vehicle to be charged. At this time, it cannot be guaranteed that the cable length can allow the charging gun to be plugged into the vehicle to be charged, resulting in inconvenience during charging.

When the cable 111 is pulled, it moves and supports in the direction of pulling the cable 111. The cable 111 is always supported at the support frame 323. There is no need to arrange the length of the wound cable 111 as in the prior art so that the charging gun 112 can be just plugged into the charging port of the vehicle to be charged.

[0030] In this embodiment, the first rotating shaft 6250 is provided with a thread passing through the second through hole 7220, and the thread is engaged with a nut 6251 that is tightly pressed against the rotating seat 322; a damping block 834 is provided inside the socket 8320, and a contact portion 8340 passing through both sides is provided at the damping block 834, and the contact portion 8340 is conical in shape and is coaxially arranged with the insert tube 835; a threaded hole 8310 passing through both sides and communicating with the insert tube 835 is provided at the first hinged seat 631; a bolt 633 is threadedly engaged at the threaded hole 8310; a top block 836 that is plugged into and engaged with the contact portion 8340 is provided at the end of the bolt 633.

[0031] By setting the top block 836 and the damping block 834 in this embodiment, when the first hinge seat 631 and the second hinge seat 632 rotate relative to each other, there is a certain friction force between the top block 836 and the damping block 834, so that the support frame 323 can be automatically positioned after tilting, so that the support frame 323 can be tilted and positioned according to the extension direction of the cable 111, and can be flexibly adjusted to support the cable 111; wherein the damping block 834 can be made of elastic rubber material, and the contact portion 8340 can be provided with an anti-slip surface to further increase the friction force; wherein the setting of the nut 6251 can be tightly pressed against the rotating seat 322 to prevent the rotating seat 322 from rotating easily, thereby achieving a certain friction damping effect.

For example, when pulling the cable 111, the slider 325 can be directly slid, thereby driving the support frame 323 to move.

[0036] In this embodiment, a support seat 224 is provided at one side of the support frame 323, and a first receiving groove 2240 is provided at the support seat 224, which passes through both sides and is away from one end of the mounting seat 321; a shock absorbing assembly 240 is provided at the support seat 224; the shock absorbing assembly 240 includes a shock absorbing seat 941 provided at the first receiving groove 2240; a second receiving groove 9410 is provided at the shock absorbing seat 941, which passes through both sides and is away from one end of the mounting seat 321; the second receiving groove 9410 is used for allowing the cable 111 to pass through And the shape is U-shaped; an insertion rod 1045 is provided at one end of the shock absorbing seat 941 away from the second receiving groove 9410; a through hole 1044 is provided at the support seat 224, which is connected with the first receiving groove 2240 and for the insertion rod 1045 to pass through, and a second limit block 1043 is provided at one end of the insertion rod 1045 passing through the first receiving groove 2240; a second compression spring 942 is sleeved on the insertion rod 1045, and the two ends of the second compression spring 942 are respectively pressed against the shock absorbing seat 941 and the first receiving groove 2240.

[0037] By providing the shock absorbing assembly 240 in this embodiment, the cable 111 can achieve shock absorption when supported by the shock absorbing seat 941, thereby preventing the heavy-weight suspended cable 111 from damaging the support seat 224 when the vehicle body 110 shakes due to, for example, passing over a speed bump. At the same time, it can also buffer the support seat 224 when improper operations such as pulling the cable 111 forcefully in an instant occur.

[0038] In this embodiment, a limiting assembly 250 for sealing the end opening of the second accommodating groove 9410 is provided at the shock absorbing seat 941; the limiting assembly 250 includes a fixing plate 951 fixed to one side of the shock absorbing seat 941, and the fixing plate 951 is rotatably matched with a second rotating shaft 952 set along the extension and retraction direction of the insertion rod 1045; the second rotating shaft 952 is connected to an L-shaped limiting plate 954, and the limiting plate 954 is used to seal the end opening of the shock absorbing seat 941 after rotation.

[0039] By setting the limiting assembly 250 in this embodiment, the end opening of the shock absorbing seat 941 is blocked by the rotating limiting plate 954, and the cable 111 can only pass through the two sides of the shock absorbing seat 941, so that the cable 111 will not fall off from the end opening of the shock absorbing seat 941 when being pulled; wherein the second rotating shaft 952 is arranged at the knob 955 for easy rotation.

[0043] By setting the roller 956 in this embodiment, the cable 111 can contact the roller 956 when passing through the shock absorbing seat 941 and pressing against the limit plate 954, so that the friction between the cable 111 and the limit plate 954 is reduced by the roller 956, and a certain protection effect is played on the limit plate 954. The roller 956 can be set with an elastic rubber material to further reduce the wear of the cable 111 and the limit plate 954 and buffer the impact of the cable 111 on the limit plate 954.

[0044] Example 2 This embodiment provides an emergency charging method, which is implemented by any of the mobile charging robots described above, and includes the following steps: S1. Move the vehicle body 110 to the side of the vehicle to be charged, adjust the position of the vehicle body 110 according to the surrounding environment, and remove the charging gun 112; S2, move the handheld charging gun 112 to the charging port of the vehicle to be charged, and plug the charging gun 112 into the charging port for charging.

[0045] Among them, the vehicle body 110 is a well-known mobile charging vehicle, which can realize automatic driving or remote control movement or a combination of the first two. Through the movable function different from the conventional charging pile, the function of emergency charging of the vehicle to be charged is realized. When the vehicle body 110 moves to the side of the vehicle to be charged, it is necessary to pay attention to the surrounding environment and charge the vehicle to be charged without affecting the passage of other vehicles. Therefore, there is a certain probability that the side of the vehicle body 110 with the charging gun 112 and the cable 111 will not be close to the vehicle to be charged, so that the entire cable 111 needs to extend toward the charging port of the vehicle to be charged, so that the cable 111 contacts the ground and is easily damaged by friction, or the entire cable 111 is kept suspended due to the length and gravity, causing the connection between the cable 111 and the vehicle body 110 or the charging gun 112 to be easily damaged; however, a mobile charging robot of the present invention can flexibly support the multi-directionally extended cable 111 through a support mechanism 120 to prevent the above problems from occurring during charging.

[0046] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0047] The present invention and its implementation methods are described schematically above, and the description is not restrictive. The embodiments shown in the embodiments are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the embodiments and designs a structure and an implementation method similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
