The user can protect the connection between the charger socket 4 and the charging port 1, and can avoid rainwater dripping on the connection position of the charger socket 4 and the charging port 1 when charging on rainy days, affecting the charging effect of the car. The side of the partition 26 close to the charging port 1 is fixedly connected to a sponge pad 27, and the cross-sectional size of the sponge pad 27 is the same as that of the partition 26. The sponge pad 27 on the partition 26 can absorb water stains splashed on the surface of the charging port 1. , to avoid too much water stains, the water stains gather together in the shape of water drops and flow downward, and there is a risk that the water drops will flow into the connection between the charger socket 4 and the charging port 1, affecting the charging effect. The end of the screw 24 away from the connecting block 22 is fixedly connected to two round rods 28, and the ends of the two round rods 28 away from the connecting block 22 are fixedly connected to the same fixing block 29. The round rods 28 cooperate with the fixing block 29 to drive the screw 24 to rotate. The user can remove the connecting ring 21 from the charger socket 4 or install and connect the connecting ring 21 to the charger socket 4 without the aid of a screwdriver. The partition 26 is made of plastic. The plastic partition 26 has a low cost and can also facilitate users to check the connection between the charger socket 4 and the charging port 1 through the plastic partition 26, which is more convenient for users to judge whether the connection between the charger socket 4 and the charging port 1 is normal.

[0034] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The auxiliary device 3 includes a connecting disk 31, which is fixedly connected to the charger socket 4. Two springs 32 are fixedly connected to the inner wall of the connecting disk 31. One end of the spring 32 close to the charging port 1 is fixedly connected to a fixing plate 33. A clamping block 34 is fixedly connected to the side of the fixing plate 33 away from the spring 32. Two clamping plates 35 are fixedly connected to one side of the charging port 1. The user can well connect the charger socket 4 to the charging port 1 to avoid looseness between the charger socket 4 and the charging port 1 when the charger socket 4 is connected to the charging port 1. The inner wall of the spring 32 is slidably connected to a telescopic rod 36. The two ends of the telescopic rod 36 are respectively fixed to the fixing plate 33 and the connecting disk 31.

The arc surface of the connecting disk 31 is provided with a plurality of heat dissipation holes 37, and the plurality of heat dissipation holes 37 are evenly distributed on the surface of the connecting disk 31. The heat dissipation holes 37 on the connecting disk 31 can dissipate heat for the charger socket 4 inside the connecting disk 31 to prevent the heat energy from accumulating inside the connecting disk 31 when the charger socket 4 is working and dissipating heat, thereby affecting the service life of the charger socket 4.

[0035] The working principle of the electric vehicle charger shield provided by the utility model is as follows: when the protective device 2 is needed, electric vehicles are now more popular, and most of the old communities do not have underground parking garages. Most electric vehicle drivers living in old communities generally choose to charge their electric vehicles in their own yards or under buildings when charging their electric vehicles. However, when thunderstorms occur frequently in summer, when the charging port 1 of the car is connected to the charger socket 4 and the car is charged, the connection is easily exposed to rainwater, which can cause a short circuit in the battery of the car being charged. In severe cases, it can induce spontaneous combustion and explosion of the battery, posing a great safety hazard. The protective device 2 can solve this problem very well. A connecting ring 21 is installed on the arc surface of the charger socket 4, a connecting block 22 is installed at one end of the connecting ring 21, and a connecting plate 23 is installed at the other end. The user can adjust the connection position of the connecting ring 21 and the charger socket 4 according to the length of the charger socket 4. After adjusting to a suitable position, the connecting ring 21 can be connected to the charger socket 4 by rotating the screw 24 in the connecting block 22 and the connecting plate 23. Two support rods 25 are installed on the connecting ring 21, and partitions 26 are installed on the two support rods 25. When the protective device 2 needs to be disassembled, the user only needs to rotate the screw 24, and the screw 24 rotates in the connecting block 22 and the connecting plate 23 to remove the connecting ring 21, so that the entire device can be removed. When in use, the user first connects the charger socket 4 with the charging port 1 of the car. When it rains, rainwater will come into contact with the partition 26 on the support rod 25 first. The rainwater that comes into contact with the partition 26 will slide to both sides of the charger socket 4 along the curvature of the surface of the partition 26. The partition 26 can successfully block the rainwater to prevent rainwater from dripping on the charger socket 4 and coming into contact with the car charging port 1. A sponge pad 27 is installed on the side of the partition 26 close to the charging port 1. The sponge pad 27 on the partition 26 can absorb water stains that splash onto the surface of the charging port 1 to prevent the water stains from gathering together in the form of water drops and flowing downward when there is too much water stains. There is a risk that the water drops will flow into the connection between the charger socket 4 and the charging port 1. The charging effect is affected. Two round rods 28 are installed at one end of the screw 24 away from the connecting block 22. A fixing block 29 is installed at one end of the two round rods 28 away from the connecting block 22. The round rods 28 cooperate with the fixing block 29 to drive the screw 24 to rotate. The user can remove the connecting ring 21 from the charger socket 4 or install and connect the connecting ring 21 to the charger socket 4 without the help of a screwdriver. The partition 26 is made of plastic. The plastic partition 26 has a low cost and can also be convenient for users to check the connection between the charger socket 4 and the charging port 1 through the plastic partition 26, so that users can judge whether the connection between the charger socket 4 and the charging port 1 is normal.

[0036] When the auxiliary device 3 is needed, after a long period of use, the charger socket 4 will become loose with the charging port 1, resulting in a loose connection between the charger socket 4 and the charging port 1. Under slight external interference, the charger socket 4 will fall off the charging port 1, resulting in the inability to continue charging the car. The auxiliary device 3 can solve this problem. The arc surface of the charger socket 4 is equipped with a connecting plate 31, and the inner wall of the connecting plate 31 is equipped with two springs 32. A fixing plate 33 is installed at one end of the spring 32, and a clamping block 34 is installed on one side of the fixing plate 33. Two clamping plates 35 are installed on one side of the charging port 1. When the charger socket 4 is not tightly connected to the charging port 1, first connect the charger socket 4 to the charging port 1, pull the fixing plate 33 at one end of the spring 32, and the spring 32 is in a stretched state at this time. The spring 32 is stretched to drive the fixing plate 33 to move in the direction of the clamping plate 35, and the clamping block 34 on one side of the fixing plate 33 is inserted into the inner wall of the clamping plate 35 to release the fixing plate 33. The winding of the spring 32 will drive the connecting plate 31 to stretch in the direction of the charging port 1, and the connecting plate 31 and the charger socket 4 are connected. The movement of the connecting disk 31 will also drive the charger socket 4 to move, so that the charger socket 4 can be more firmly fixed inside the charging port 1 by winding up the spring 32. When charging is finished, the user first pulls the card block 34 out of the card plate 35, and the card plate 35 releases the restriction on the card block 34. The card block 34 and the fixing plate 33 will move toward one end of the connecting disk 31 through the stretching of the spring 32, and the user can take the charger socket 4 out of the charging port 1. A telescopic rod 36 is installed inside the spring 32. When the spring 32 is stretched, the spring 32 The telescopic rod 36 inside the spring 32 can limit the movement of the spring 32 to prevent the spring 32 from deforming when the spring 32 is stretched. The telescopic rod 36 can limit the stretching of the spring 32 while also increasing the service life of the spring 32. The arc surface of the connecting disk 31 is provided with a plurality of heat dissipation holes 37. The heat dissipation holes 37 on the connecting disk 31 can dissipate heat for the charger socket 4 inside the connecting disk 31 to prevent the heat energy from accumulating inside the connecting disk 31 when the charger socket 4 is working and dissipating heat, thereby affecting the service life of the charger socket 4.
