Description

Technical Field

[0001] This utility model relates to the field of charging dock technology, and in particular to a three-safety-door anti-electric shock structure for a charging dock. Background Technology

[0002] With the increasing popularity of electric vehicles, safety accidents caused by electric vehicle charging are also emerging. In order to avoid safety accidents caused by charging electric vehicles upstairs or inside homes, many communities now set up electric vehicle charging stations in public areas to provide residents with the convenience of outdoor charging. As a result, the demand for electric vehicle charging piles and the associated electric vehicle charging sockets is increasing, and their functional requirements are also rising.

[0003] A search revealed that Chinese utility model patent CN202321362403.1 discloses a charging socket for electric vehicles, aiming to solve the technical problem that, under existing technology, electric vehicles are often far from charging sockets, making it difficult for chargers to connect to the charging socket and the electric vehicle. This charging socket for electric vehicles includes a mounting backplate and a socket body; a cover is provided on one side of the mounting backplate, and the socket body is mounted on the side of the cover away from the mounting backplate; an adjustment groove is formed along the length of the side of the cover facing the socket body, and a sealing plate that movably blocks the adjustment groove is provided inside the cover; through holes are provided at both ends of the cover for the ends of the sealing plate to pass through; a slider is provided on the sealing plate, the slider slidingly embedding into the adjustment groove and connecting to the socket body; a protective component is provided on the slider, the protective component including a protective sleeve fixedly inserted on the slider and a rubber sleeve inserted inside the protective sleeve, the protective sleeve penetrating the sealing plate.

[0004] While the existing charging sockets can meet basic usage needs, their conductive sheets are all wrapped in insulating rubber. As the rubber ages, leakage cannot be avoided. This is especially true for charging stations that use AC power. Once leakage occurs, it can cause serious safety accidents. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a three-safety-door anti-electric shock structure for a charging socket, in order to solve the problem that existing charging sockets cannot avoid leakage and are prone to leakage, which can cause serious safety accidents.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A three-safety-door anti-electric shock structure for a charging base includes a charging base body. The charging base body contains several charging posts, and an anti-electric shock sleeve is provided on the outer side of each charging post. Several safety doors are rotatably mounted on the anti-electric shock sleeve. Each safety door includes a first safety door, a second safety door, and a third safety door arranged in a triangular pattern with their vertices sequentially distributed. The anti-electric shock sleeve has several through holes for the ends of the safety doors to extend out. The first, second, and third safety doors are respectively abutted against the inner side of the anti-electric shock sleeve by springs.

[0008] Preferably, the charging dock body includes an embedded part, a main board part, and an outer cover part. The main board part is integrally connected to the embedded part and the outer cover part, and the outer cover part surrounds the periphery of the anti-electric shock sleeve.

[0009] Preferably, the first safety door, the second safety door, and the third safety door each include a toggle plate, a rotating column, and an inner baffle, wherein the rotating column is integrally connected to the toggle plate and the inner baffle, respectively.

[0010] Preferably, the spring is sleeved on the rotating column, the middle part of the spring abuts against the toggle plate, and the end of the spring abuts against the inner side of the charging base body.

[0011] Preferably, the front end of the anti-electric shock sleeve has a battery cell insertion hole, and the inner baffle is located directly behind the battery cell insertion hole.

[0012] Preferably, the inner side of the anti-electric shock sleeve is provided with a plurality of safety door mounting grooves that are adapted to the safety door, and the safety door is respectively installed on the safety door mounting grooves.

[0013] By adopting the above technical solution, the present invention provides a three-safety-door anti-electric shock structure for a charging dock, which has the following beneficial effects: An anti-electric shock sleeve is provided on the outer side of the charging column in the three-safety-door anti-electric shock structure. Several safety doors are rotatably installed on the anti-electric shock sleeve. Each safety door includes a first safety door, a second safety door, and a third safety door arranged in a triangular pattern with their vertices sequentially distributed. The anti-electric shock sleeve has movable through holes for the ends of the safety doors to extend out. The first, second, and third safety doors are respectively abutted against the inner side of the anti-electric shock sleeve by springs. When the charging gun is inserted, the outer side of the charging gun first contacts the ends of the first, second, and third safety doors. This causes the first, second, and third safety doors to rotate from a vertical to a horizontal position, facilitating the insertion of the charging cells from the charging gun into the inside of the charging base. When the charging gun is pulled out, the first, second, and third safety doors rotate from a horizontal to a vertical position under the action of springs, thus blocking the inside of the charging base and preventing other objects from inserting and touching the internal conductive cells. By adding an anti-electric shock sleeve, and rotating the first, second, and third safety doors on the anti-electric shock sleeve to block the internal conductive cells, it prevents external objects from directly inserting and accidentally touching the cells, thus providing a high level of safety and preventing electric shock accidents.
