[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) In the process of connecting the charging gun to the gun socket, this solution can absorb the residual water in the charging gun interface through the columnar absorbent sponge, realize the function of instantly clearing the water in the charging gun interface, effectively reduce the risk of electrochemical corrosion and other adverse phenomena caused by water retention in the interface area, and thus extend the overall service life of the charging gun. The columnar absorbent sponge can absorb and store water, and then the water can be transferred to the disc-shaped diffusion sponge with a larger surface area, which promotes the distribution of water over a larger area, accelerates the evaporation rate of water inside the columnar sponge and the disc sponge, and ensures that the evaporated water vapor can flow smoothly and be discharged through the horizontally inclined ventilation pipe, thereby realizing efficient treatment of the water in the charging gun interface after cleaning.

[0019] (2) In this solution, when the charging gun is pulled out from the gun socket, the charging gun will drive the sealing cover to separate from the charging pile body simultaneously, but the sealing cover will not be directly detached from the gun socket. This can reduce the possibility that rainwater will enter the charging gun interface after the charging gun is pulled out, and when the user may insert the charging gun again, the moisture inside the interface cannot be cleared in time, further reducing the probability of negative effects such as electrochemical corrosion caused by residual moisture in the interface area, thereby effectively extending the service life of the charging gun.

[0020] (3) This solution enables the movable frame to slide along the outer surface of the charging cable, and with the help of the guidance of the guide skirt and the coordination of the movable frame, it is possible to comb and restore the charging cable in a spirally twisted state, thereby effectively preventing the charging cable from becoming stiff, becoming more difficult to bend, and having reduced flexibility due to continuous spiral twisting during use. When the user pulls the charging cable to connect the charging gun to the electric vehicle, the user can experience a smoother and more labor-saving operation process, which significantly improves the convenience and efficiency of the charging operation.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6A charging pile plug assembly includes a charging gun 102, a charging pile body 101 and a charging cable 103, wherein the charging cable 103 is fixedly connected to the charging pile body 101, and the charging gun 102 is fixedly connected to the charging cable 103. A moisture-proof mechanism is arranged inside the charging pile body 101, and the moisture-proof mechanism includes a sealing cover 206 arranged inside the charging pile body 101. The front end of the sealing cover 206 is fixedly connected to a limited annular plate 204, and the inner ring of the limited annular plate 204 is fixedly connected to an annular slide rail 205, and the inner ring of the annular slide rail 205 is slidably connected to a front end plate 201. The front end plate The inner circle of 201 is fixedly connected with a gun socket 223, and the charging gun 102 is inserted into the inside of the gun socket 223. A disc sponge 221 is arranged at the rear end of the gun socket 223. Water is transferred to the disc sponge 221 with a larger surface area, which can accelerate the evaporation of water in the columnar sponge 220 and the disc sponge 221. The inside of the sealing cover 206 is fixedly connected with an electric push rod 224. The surface of the disc sponge 221 is fixedly connected with a columnar sponge 220 that matches the charging gun 102. The columnar sponge 220 can be used to absorb the water in the interface of the charging gun 102 and transfer the water to the disc sponge 221 with a larger surface area.

[0036] Among them, a support frame 222 is arranged inside the disc sponge 221 and the columnar sponge 220, and the power output end of the electric push rod 224 is fixedly inserted into the support frame 222. The support frame 222 can prevent the columnar sponge 220 from being distorted, which affects its insertion into the interface of the charging gun 102. A transverse inclined ventilation pipe 203 is fixedly inserted on the surface of the front end plate 201, and the evaporated water can be discharged through the transverse inclined ventilation pipe 203 flowing on both sides. The moisture-proof mechanism also includes a controller arranged inside the charging pile body 101, and the infrared sensor 225 is communicatively connected to the controller; the controller is used to control the electric push rod 224 to push the disc sponge 221, and the transverse inclined ventilation pipe 203 is divided into two groups, and the number of transverse inclined ventilation pipes 203 in each group is four. The four transverse inclined ventilation pipes 203 are shortened from top to bottom and the front end is connected to the longitudinal inclined ventilation pipe 202. The inclined transverse inclined ventilation pipe 203 and the longitudinal inclined ventilation pipe 202 can prevent external water from flowing into the sealing cover 206.

[0037] By adopting the above technical solution, when the charging gun 102 is not needed, the charging gun 102 is inserted into the gun socket 223, and the insertion of the charging gun 102 is detected by the infrared sensor 225. Based on the signal detected by the infrared sensor 225, the electric push rod 224 can be controlled to push the columnar sponge 220 on the disc sponge 221 into the interface on the charging gun 102. At this time, the columnar sponge 220 can be used to absorb the water in the interface of the charging gun 102. After the water is cleaned, the electric push rod 224 drives the columnar sponge 220 to remove the water from the charging gun 102. The cylindrical sponge 220 is drawn out from the interface on the charging gun 102 to avoid the water-containing cylindrical sponge 220 being located inside the interface of the charging gun 102, which causes the inside of the interface of the charging gun 102 to remain in a wet state and cannot prevent the electrochemical corrosion caused by water. The water in the cylindrical sponge 220 is transferred to the disc sponge 221 with a larger surface area, so as to accelerate the evaporation of the water in the cylindrical sponge 220 and the disc sponge 221. The evaporated water can be discharged through the transverse inclined ventilation pipes 203 circulating on both sides, so as to realize the cleaning of the water in the interface of the charging gun 102 and the treatment of the cleaned water.

[0038] The infrared sensor 225 may be a prior art, for example, the model of the infrared sensor 225 may be a prior art TCRT model, which is not specifically limited in the present embodiment. The controller may also be a prior art, for example, the controller may be a Deutronic D-Sinus controller, which is not specifically limited in the present embodiment.

[0039] like Figures 2 to 6 As shown, the surface of the charging gun 102 is rotatably connected to a position limiting roller 215, and the number of the position limiting rollers 215 is multiple, and the multiple position limiting rollers 215 are divided into two groups. The back of the front end plate 201 is fixedly connected to a first support seat 217, and a guide plate 218 is inserted into the interior of the first support seat 217 for sliding. The lower end of the guide plate 218 is fixedly connected to a resistance block 216 that matches the position limiting roller 215, so that the resistance block 216 is stuck between the corresponding two position limiting rollers 215, and the charging gun 102 can be kept in the inserted state after the charging gun 102 is inserted into the gun insertion seat 223. A resistance spring 219 is fixedly connected between the resistance block 216 and the first support seat 217, and the resistance spring 219 applies pressure to make the resistance block 216 stuck between the corresponding two position limiting rollers 215.

[0040] Among them, the rear end tip of the sealing cover 206 is fixedly connected with a return spring 209, the rear end tip of the sealing cover 206 is fixedly connected with a position limiting pull rope 210, the return spring 209 is sleeved on the outside of the position limiting pull rope 210, the position limiting pull rope 210 can limit the movement of the sealing cover 206, the interior of the charging pile body 101 is fixedly connected with a connecting frame 212, the rear end of the return spring 209 is fixedly connected to the surface of the connecting frame 212, the return spring 209 can drive the sealing cover 206 to return to its original position, the interior of the charging pile body 101 is rotatably connected with a rotating seat 211, the position limiting pull rope 210 One end is fixedly connected to the front end of the rotating seat 211, and the position limiting pull rope 210 passes through the middle of the connecting frame 212. The arc surface of the sealing cover 206 is fixedly connected to the support plate 207, and a correction spring 208 is fixedly connected between the support plate 207 and the connecting frame 212. The four correction springs 208 will drive the sealing cover 206 to rotate and align during the recovery process, so that the user can insert the charging gun 102 into the gun plug seat 223 after completing charging. There are four correction springs 208, and the sealing cover 206 is in the shape of a cone, so that the sealing cover 206 can be accurately moved to its original position and re-fit the charging pile body 101.

[0041] By adopting the above technical solution, since the charging gun 102 needs to perform payment operation before use, and new users or older users who are not proficient and do not know how to use it often remember the need to pay after pulling out the charging gun 102. In the process of pulling out the charging gun 102 from the gun socket 223, the charging gun 102 will drive the sealing cover 206 to be pulled out from the charging pile body 101, and will not be directly separated from the gun socket 223, which can reduce the occurrence of rainwater flowing into the charging gun 102 interface after the charging gun 102 is pulled out and the user re-inserts the charging gun 102, resulting in the water in the charging gun 102 interface cannot be cleaned in time;

[0042] When the user decides to use the device, the charging gun 102 is pulled out, which drives the sealing cover 206 to continue to move until the position limiting rope 210 is stretched straight and the sealing cover 206 can no longer move. During the process of pulling the charging gun 102 out of the gun seat 223, pressure is applied during the pulling process, and the resistance block 216 squeezes and passes over the position limiting rollers 215 in sequence, so that the charging gun 102 can be pulled out. After the charging gun 102 is inserted into the gun seat 223, the resistance spring 219 applies pressure to make the resistance block 216 stuck between the two corresponding position limiting rollers 215, so that the charging gun 102 can remain inserted into the gun seat 223, thereby preventing the charging gun 102 from falling off the gun seat 223 under natural conditions.

[0043] During the process of pulling out the charging gun 102, the correction spring 208 and the return spring 209 are both in a stretched state. After the charging gun 102 is completely pulled out, the return spring 209 can drive the sealing cover 206 back to its original position. During the recovery process of the four correction springs 208, the sealing cover 206 will be driven to rotate and align, so that the user can insert the charging gun 102 into the gun socket 223 after completing charging.

[0044] See also Figure 2 , Figures 7 to 11 A charging pile with a charging pile gun plug assembly, a distortion correction mechanism, the distortion correction mechanism is arranged at the lower end of the charging pile body 101, the distortion correction mechanism includes a guide skirt 301 fixedly connected to both sides of the charging cable 103, the surface of the charging cable 103 is sleeved with a mobile frame 302, the inner side of the mobile frame 302 is provided with a guide groove 313 matched with the guide skirt 301, the guiding cooperation of the mobile frame 302 and the guide skirt 301 can make the spirally twisted charging cable 103 be smoothed and restored, and both sides of the mobile frame 302 are fixedly connected with a mobile handle 303.

[0045] Among them, the internal rotation of the guide groove 313 is connected to the guide shaft 311, and the guide shaft 311 can reduce the friction resistance generated when the movable frame 302 moves, making its movement more labor-saving and reducing the wear on the guide skirt 301. A ball 312 is provided at one end of the guide shaft 311, and the ball 312 can reduce the wear on the side of the charging cable 103.

[0046] Among them, an elastic pull rope 309 is fixedly connected to the inner middle section of the charging pile body 101, and a connector 310 is fixedly connected to the front end of the elastic pull rope 309. After the recovery operation is completed, the elastic pull rope 309 can drive the mobile frame 302 to return to its original position for next use. The connector 310 is fixedly connected to the upper surface of the mobile frame 302, and a second support seat 305 is fixedly connected to the surface of the charging cable 103. The upper end of the second support seat 305 is fixedly connected to a path limiting frame 304. The elastic pull rope 309 can bend along the curved path of the charging cable 103 through the path limiting frame 304. The shape of the path limiting frame 304 is "C"-shaped. The C-shaped structure can not affect the movement of the mobile frame 302 while the elastic pull rope 309 passes through the path limiting frame 304, so that the mobile frame 302 can be reset later. There are multiple path limiting frames 304, and they are evenly arranged on the surface of the charging cable 103.

[0047] Among them, the lower front end of the charging pile body 101 is fixedly connected to the third support seat 306, the lower part of the third support seat 306 is fixedly connected to the fixed clamping plate 308, the upper part of the third support seat 306 is fixedly connected to the second connecting plate 315, the front end of the second connecting plate 315 is rotatably connected to the first connecting plate 314, the lower surface of the first connecting plate 314 is fixedly connected to the movable clamping plate 307, and the upper surface of the second connecting plate 315 is fixedly connected to the rebound plate 316. When the movable frame 302 is reset, the cooperation of the fixed clamping plate 308, the movable clamping plate 307 and the rebound plate 316 can play a buffering role to avoid direct impact on the charging pile body 101 and causing damage. The rebound plate 316 is in an arc shape and is rotatably connected to the contact shaft 317 at the front end. The rollable contact shaft 317 can prevent the rebound plate 316 from repeatedly scratching on the first connecting plate 314, causing serious wear of the rebound plate 316 and affecting its use.

[0048] By adopting the above technical solution, if the charging cable 103 is spirally twisted during use, which makes the charging cable 103 stiff, difficult to bend, and less flexible, making it difficult to pull the charging cable 103 to insert the charging gun 102 into the electric vehicle, then the two movable handles 303 can be held to drive the movable frame 302 to move on the surface of the charging cable 103, and the spirally twisted charging cable 103 can be restored by pulling it back through the guidance of the guide skirt 301 and the cooperation of the movable frame 302;

[0049] In the process of driving the mobile frame 302 to move, the elastic pull rope 309 will be stretched. After the recovery operation is completed, the mobile frame 302 can be driven back to its original position through the elastic pull rope 309 for next use. In the process of the elastic pull rope 309 being stretched, the path limiting frame 304 can make the elastic pull rope 309 bend along the curved path of the charging cable 103, and the C-shaped structure can not affect the movement of the mobile frame 302 while the elastic pull rope 309 passes through the path limiting frame 304, so that the mobile frame 302 can be reset later. When the mobile frame 302 is reset, the mobile handle 303 will enter between the fixed clamp plate 308 and the movable clamp plate 307, and can play a buffering role through the cooperation of the rebound plate 316 to avoid direct impact on the charging pile body 101 and cause damage.

[0050] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
