[0002] With the continuous development of new energy batteries and other fields, new energy vehicles are becoming more and more common. The most widely promoted new energy vehicle today is electric vehicles, which are driven by electricity and need to be recharged. Usually, electric vehicles are equipped with a charging station, and the electric vehicle is charged by inserting a charging gun into the charging station.

In order to solve this problem, some charging stations are equipped with protective doors. However, after adding protective doors to existing charging stations, the charging station will be larger in size, which limits the design of the vehicle, and it cannot be directly replaced on the original installation hole position, and the installation hole position needs to be redesigned.

[0027] Example

[0028] See also Figures 1 to 7 The utility model provides an anti-electric shock charging device. The anti-electric shock charging device of the utility model comprises an anti-electric shock charging seat 1 and a charging gun 2 for charging the anti-electric shock charging seat 1; the anti-electric shock charging seat 1 is provided with a charging slot 10, and the charging slot 10 is provided with a plurality of charging connectors 11 and an anti-electric shock device 12, and the anti-electric shock device 12 is rotatably covered on the charging connector 11.

[0029] Specifically, see Figures 1 to 5 The charging connector 11 includes a charging terminal 111 and a protective sleeve 112. The protective sleeve 112 is disposed in the charging slot 10, and the charging terminal 111 is disposed in the protective sleeve 112. The charging gun 2 is provided with a sleeve groove 20 corresponding to the protective sleeve 112, and a charging plug 21 is disposed in the sleeve groove 20. The charging plug 21 corresponds to the charging terminal 111. When the protective sleeve 112 is inserted into the sleeve groove 20, the charging plug 21 is inserted into the protective sleeve 112 and contacts the charging terminal 111 for charging.

[0030] See also Figure 6 to Figure 7 The anti-electric shock device 12 includes a plurality of shutter mechanisms 121, and the shutter mechanisms 121 include a lever assembly 1211, a rotating mounting shaft 1212, and a protective blocking assembly 1213. The rotating mounting shaft 1212 is disposed on the lever assembly 1211, and its two ends are exposed on both sides of the lever assembly 1211. The lever assembly 1211 rotates with the rotating mounting shaft 1212 as a fulcrum; the protective blocking assembly 1213 is disposed at one end of the lever assembly 1211. The shutter mechanism 121 is rotatably disposed on the side wall of the protective sleeve 112 through the rotating mounting shaft 1212. Furthermore, the rotating mounting shaft 1212 is perpendicular to the axis of the protective sleeve 112. One end of the lever assembly 1211 provided with the protective blocking assembly 1213 extends into the protective sleeve 112, and the other end of the lever assembly 1211 extends out of the protective sleeve 112. When not charged, the protective blocking assembly 1213 covers the charging terminal 111.

[0031] When the charging gun 2 is inserted into the anti-electric shock charging seat 1, the charging connector 11 is inserted into the sleeve groove 20; since one end of the lever assembly 1211 extends out of the protective sleeve 112, the sleeve groove 20 presses the lever assembly 1211 downward, so that the outward end of the lever assembly 1211 rotates toward the bottom of the protective sleeve 112, and the lever assembly 1211 rotates around the rotating mounting shaft 1212, and the inward end of the lever assembly 1211 flips up, and the protective blocking assembly 1213 moves accordingly, exposing the charging terminal 111; at this time, the charging plug 21 can continue to be inserted into the protective sleeve 112 and contact the charging terminal 111.

[0032] Furthermore, the protective blocking assembly 1213 is a shutter baffle, and the shutter baffles of each shutter mechanism 121 are combined to form a cover, which covers the charging terminal 111. In some embodiments, the anti-electric shock device 12 includes four shutter mechanisms 121, and the shutter baffles are fan-shaped. The shutter baffles arranged on the same protective sleeve 112 are combined to form a circular cover; the circular cover can better cover the mouth of the protective sleeve 112, thereby improving the protection effect.

[0033] Furthermore, the anti-electric shock device 12 further includes an elastic reset component 122, which is used to reset the shutter mechanism 121 when the charging connector 11 is pulled out of the sleeve slot 20. In some embodiments, the elastic reset component 122 is a torsion spring, which is sleeved with a rotating mounting shaft 1212, wherein one torsion spring leg abuts against the protective sleeve 112; when the charging gun 2 is pulled out of the anti-electric shock charging seat 1, the elastic force of the torsion spring pushes the shutter mechanism 121 to reset.

[0034] In some embodiments, the protective sleeve 112 is provided with a plurality of shutter slots 1120, and the shutter slots 1120 are provided with shaft slots 1120a on both sides; the shutter mechanism 121 is provided in the shutter slot 1120, and the rotating mounting shaft 1212 is provided in the shaft slot 1120a. Furthermore, a lever slot 1120b for accommodating the lever assembly 1211 is provided below the side of the shutter slot 1120 outside the protective sleeve 112, and a limit table for limiting the protective blocking assembly 1213 is provided below the side of the shutter slot 1120 inside the protective sleeve 112. When the charging gun 2 is inserted into the anti-electric shock charging seat 1, the charging connector 11 is inserted into the sleeve slot 20, and the outward end of the lever assembly 1211 rotates toward the bottom of the protective sleeve 112 and is received in the lever slot 1120b, so as to prevent the outward end of the lever assembly 1211 from obstructing the charging connector 11 from being inserted into the sleeve slot 20. When the charging gun 2 is pulled out from the anti-electric shock charging seat 1, the charging connector 11 is pulled out of the sleeve groove 20, and the inner end of the lever assembly 1211 rotates downward toward the protective sleeve 112. The limit platform resists the lever assembly 1211 to limit the protective blocking assembly 1213 to prevent the protective blocking assembly 1213 from continuing to move downward.

[0035] In some embodiments, the protective sleeve 112 further includes an assembly cover 1121, on which a charging socket is provided; a shutter slot 1120 is provided at the upper end of the protective sleeve 112, and the upper end of the shutter slot 1120 is open. The upper end of the protective sleeve 112 is also provided with a plurality of second assembly fittings 1121b, and the assembly cover 1121 is provided with a plurality of first assembly fittings 1121a, and the first assembly fittings 1121a and the second assembly fittings 1121b are mutually connected, so that the assembly cover covers the upper end of the protective sleeve. When installing the anti-electric shock device 12, the shutter mechanism 121 is inserted into the shutter slot 1120 from above the shutter slot 1120, and then the assembly cover 1121 is covered on the protective sleeve 112, and the installation steps are simple and convenient. Furthermore, the first assembly fitting 1121a is a hot melt hole, and the second assembly fitting 1121b is a hot melt column; during installation, the hot melt column is inserted into the hot melt hole, and then the hot melt column is heated to soften it, and the assembly cover 1121 is riveted; the hot melt column can improve the combined strength of the assembly cover 1121 and the protective sleeve 112, and has a small volume, which can save space.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
