Description

Technical Field

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

[0002] Against the backdrop of a global push for a low-carbon economy, the focus of industrial development is shifting towards energy conservation and reducing greenhouse gas emissions, with the development of new energy sources becoming the mainstream trend. Electricity boasts zero emissions, high energy efficiency, and low operating and maintenance costs. The promotion and widespread adoption of electric vehicles and electric motorcycles can effectively alleviate the environmental pressures imposed by human development. Charging sockets are essential accessories for charging energy storage modules such as batteries. Electric vehicles, energy storage cabinets, electric motorcycles, and charging piles are all equipped with charging sockets to connect to charging guns. Because the charging gun is directly connected to the charging socket, and the charging connector is always energized, safety issues with the charging socket can easily arise.

[0003] A search revealed that Chinese utility model patent CN202120577285.0 discloses an electric two-wheeled vehicle anti-electric shock charging socket, featuring a controllable on / off circuit. The output of this controllable on / off circuit is connected to the power input terminal of the electric vehicle's internal battery; the input terminal is connected to the power output terminal of an external charger. The controllable on / off circuit is switched on or off by a control signal from the external charger. This utility model, by incorporating a controllable on / off circuit between the charging socket's charging terminals and the battery, allows the circuit to connect or disconnect the battery and charging port under the control of a signal. This avoids the risk of electric shock to the user due to a live plug, and also prevents accidents such as overheating of the wiring harness or even fires caused by short circuits.

[0004] For example, Chinese utility model patent application CN202321407892.8 discloses a charging dock. The charging dock includes: a charging dock housing; and a pipe connector installed inside the charging dock housing. The pipe connector has a first pipe joint and a second pipe joint that communicate with each other. The first pipe joint is used to connect to the cooling core tube in the charging cable, and the second pipe joint is used to connect to a cooling circuit, allowing cooling fluid to flow through the pipe connector and the charging cable to cool the interior of the charging dock housing and the charging cable. In this utility model, the pipe connector disposed inside the charging dock housing connects the cooling core tube of the charging cable to the cooling circuit, allowing cooling fluid to flow through the pipe connector and the charging cable, thereby achieving sufficient cooling of the interior of the charging dock housing and the charging cable.

[0005] While the existing charging docks can meet basic usage needs, they lack internal anti-electric shock components or rely solely on internal circuitry to control power cut-off. If people handle the plugging and unplugging improperly, they may come into contact with the live conductive cells, potentially leading to electric shock accidents. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a two-safety-door anti-electric shock structure for a charging base, which addresses the above-mentioned defects of the prior art. By adding an anti-electric shock sleeve and rotating an upper safety door and a lower safety door on the anti-electric shock sleeve to block the internal conductive battery cell, it avoids accidental contact and electric shock accidents, thus playing a role in preventing electric shock and providing high safety.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A charging base with a two-safety-door anti-electric shock structure includes a charging base body, a plurality of charging posts are provided inside the charging base body, and an anti-electric shock sleeve is provided on the outer side of the charging posts. An upper safety door and a lower safety door are rotatably installed on the anti-electric shock sleeve. The upper safety door and the lower safety door are symmetrically arranged on the anti-electric shock sleeve. The anti-electric shock sleeve has a safety door movable through hole for the ends of the upper safety door and the lower safety door to extend out. The upper safety door and the lower safety door are both abutted against the inner side of the anti-electric shock sleeve by springs.

[0009] 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.

[0010] Preferably, both the upper safety door and the lower safety door include a toggle plate, a rotating column, and an inner baffle, with the rotating column being integrally connected to the toggle plate and the inner baffle, respectively.

[0011] 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.

[0012] 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.

[0013] Preferably, the inner side of the anti-electric shock sleeve is provided with a safety door mounting groove that is compatible with the upper safety door and the lower safety door, and both the upper safety door and the lower safety door are installed on the safety door mounting groove.

[0014] The present invention provides a two-safety-door anti-electric shock structure for a charging dock, which has the following advantages: An anti-electric shock sleeve is provided on the outer side of the charging column in the two-safety-door anti-electric shock structure. An upper safety door and a lower safety door are rotatably mounted on the anti-electric shock sleeve. The upper and lower safety doors are symmetrically arranged on the anti-electric shock sleeve. The anti-electric shock sleeve has safety door movable through holes for the ends of the upper and lower safety doors to extend out. Both the upper and lower safety doors abut against the inner side of the anti-electric shock sleeve via springs. When the charging gun is inserted, the outer side of the charging gun first contacts the upper and lower safety doors. The ends of the doors contact each other, thereby pushing the upper and lower safety doors to rotate from a vertical to a horizontal position, facilitating the insertion of the charging cells on the charging gun into the inside of the charging base body. When the charging gun is pulled out, the upper and lower safety doors rotate from a horizontal to a vertical position under the action of springs, thereby blocking the inside of the charging base body and preventing other objects from inserting and touching the internal conductive cells. By adding an anti-electric shock sleeve, and rotating the upper and lower safety doors on the anti-electric shock sleeve to block the internal conductive cells, accidental contact leading to electric shock accidents is prevented, thus achieving a high level of safety.

[0023] like Figure 1-4 As shown, the charging base with a two-safety-door anti-electric shock structure includes a charging base body 1, inside which are arranged several charging posts 2. An anti-electric shock sleeve 3 is provided on the outer side of each charging post 2.
