[0020] Third: when the charging gun of the present invention is inserted into the socket, the sponge cover can clean and absorb the water vapor on the gun tip in time to ensure the dryness of the gun tip; when the charging gun is away from the socket, the water vapor on the sponge cover can be drained in time to ensure the water absorption effect of the sponge cover; and the plug-in cavity is connected with the inner cavity of the charging cabinet body, the hot air in the inner cavity of the charging cabinet body will be discharged along the air outlet channel, and the sponge cover will be dried at the same time to further ensure the water absorption effect of the sponge cover.

[0021] Fourthly, when a fire occurs in the main body of the charging cabinet, the driving motor of the present invention drives the screw rod to rotate forward and reverse, thereby driving the screw rod sleeve to move up and down, and the first solenoid valve port is opened, and dry powder is sprayed along the first connecting pipe and the jet pipe port to extinguish the fire inside the charging cabinet main body; when a fire occurs at the connection port between the charging gun and the tram, the second solenoid valve port is opened, and the second solenoid valve port passes through the sealing sleeve through the connecting hose, so that the dry powder can be sprayed directly to the connection port between the charging gun and the tram, so as to extinguish the fire in time.

[0042] Example

[0043] like Figure 1-Figure 13 As shown, the present invention provides a multifunctional energy storage type supercharging device, including a charging cabinet body 1, a charging gun 2, one end of the charging gun 2 is connected to the charging cabinet body 1 through a wire, and the other end of the charging gun 2 is provided with a gun head 201, and a ring sleeve 202 is sleeved on the outer peripheral wall of the gun head 201, and one end of the ring sleeve 202 is fixedly connected to a first annular spring 203, and the other end of the first spring 203 is fixedly connected to the charging gun 2, a sealing component is provided on the ring sleeve 202, and a connecting component is provided on one side of the charging cabinet body 1;

[0044] The connecting component includes a shell 204, the inner cavity of the shell 204 is connected to the charging cabinet body 1, four slide grooves 205 are opened in the shell 204, and a slider 206 is elastically connected in the slide groove 205. The slider 206 is fixedly connected to a connecting block 207 at one end close to the sealing component. The connecting block 207 is on the surface of the shell 204. A sealing block 208 is also fixedly connected to the slider 206. An insertion port 209 for the gun head 201 to pass through is opened in the center of the shell 204. The sealing component cooperates with the four connecting blocks 207, and the sealing component is used to push the four connecting blocks 207 to move linearly.

[0045] Specifically: when the electric vehicle is fully charged, align the charging gun 2 with the plug interface 209, align the sealing assembly with the four connecting blocks 207, and then push the charging gun 2 to move toward the plug interface 209. The sealing assembly pushes the four connecting blocks 207 to expand the four connecting blocks 207 outward, so that the four sealing blocks 208 enter the corresponding slide grooves 205 respectively, thereby opening the plug interface 209. As the charging gun 2 continues to move, the gun head 201 is inserted into the plug interface 209. Conversely, after the charging gun 2 is taken out of the plug interface 209, the four sealing blocks 208 are used to seal the plug interface 209.

[0046] It is understandable that after the charging gun 2 is unplugged from the plug interface 209 , the internal environment of the shell 204 is in a sealed state, preventing foreign matter and water vapor from entering, ensuring the dryness of the inside of the shell 204 , and protecting the inserted charging gun 2 .

[0047] The sealing assembly includes four connecting rods 216, four connecting grooves 217 are opened on the ring sleeve 202, and connecting shafts are fixedly connected in the four connecting grooves 217. The connecting shafts are elastically connected to the corresponding connecting rods 216. A recess 210 for inserting the connecting rods 216 is opened on the connecting block 207, and the four connecting rods 216 are commonly wrapped with a sealing sleeve 211.

[0048] A plug-in cavity 212 is provided in the charging cabinet body 1, and the plug-in cavity 212 is connected to the inner cavity of the shell 204. A mounting plate 213 is fixedly connected to the inner wall of the plug-in cavity 212, and an elastic sleeve rod 214 is fixedly connected to the mounting plate 213. A plug connector 215 connected to the gun head 201 is fixedly connected to the end of the elastic sleeve rod 214.

[0049] Specifically: when the sealing component moves toward the plug interface 209, the connecting rod 216 will be inserted into the corresponding notch 210. As the sealing component moves, the connecting rod 216 will rotate around the connecting axis and push the connecting block 207 at the same time, so that the connecting block 207 and the sealing block 208 are expanded outward to realize the opening action of the plug interface 209. On the contrary, when the sealing component moves away from the plug interface 209, the slider 206 will elastically reset in the slide groove 205 and drive the sealing block 208 to reset, so that the four sealing blocks 208 re-seal the plug interface 209.

[0050] Note: See Figure 8 When the charging gun 2 is connected to the socket 209, the sealing sleeve 211 will fit with the outer wall of the shell 204, so that the charging gun 2 and the socket 209 are both inside the sealing sleeve 211 for waterproof protection. When the charging gun 2 is connected to the electric vehicle, the sealing sleeve 211 can also provide waterproof protection for the charging port of the electric vehicle, thereby meeting the charging requirements in heavy rainy weather.

[0051] The inner wall of the outer shell 204 is rotatably connected to a ring plate 3, and a sponge cover 301 is fixedly connected to the end of the ring plate 3. A rotating motor 302 is also fixedly connected to the inner wall of the plug-in cavity 212, and a transmission gear 303 is fixedly connected to the output shaft of the rotating motor 302. A plurality of transmission teeth are provided on the outer peripheral wall of the ring plate 3, and the transmission gear 303 is meshed with the transmission teeth.

[0052] A pressure plate 304 is provided at the bottom of the plug-in cavity 212, and one end of the pressure plate 304 has an inclined guide surface 305. A guide rod 306 is fixedly connected to the bottom of the plug connector 215, and a protrusion 307 is fixedly connected to the bottom of the guide rod 306. The protrusion 307 can drive the pressure plate 304 to move upward through the guide surface 305.

[0053] A connecting column is fixedly connected to the inner side of the pressure plate 304, a reset groove is opened on the inner side of the plug-in cavity 212, a second spring is arranged in the reset groove, the second spring is fixedly connected to the connecting column, and an air outlet channel 308 is provided at the bottom of the plug-in cavity 212, and the air outlet channel 308 is connected to the external environment.

[0054] Specifically: after the charging gun 2 enters the plug interface 209, the gun head 201 will be connected with the plug connector 215, and the gun head 201 will squeeze the plug connector 215, so that the plug connector 215 moves to the left, and at the same time, the sponge cover 301 can contact the outer periphery of the charging gun 2, so as to wipe and absorb water from the charging gun 2 to ensure that the charging gun 2 is dry;

[0055] After the charging gun 2 leaves the plug interface 209, the elastic sleeve rod 214 is reset and drives the plug connector 215 to move rightward. The movement of the plug connector 215 drives the guide rod 306 and the protrusion 307 to move synchronously, thereby pushing the pressing plate 304 to move upward. The pressing plate 304 will open the air outlet channel 308 and squeeze the sponge cover 301. At this time, the rotating motor 302 drives the ring plate 3 and the sponge cover 301 to rotate. The rotation of the sponge cover 301 cooperates with the squeezing effect of the pressing plate 304 to drain the sponge cover 301, so that the sponge cover 301 remains dry, and the squeezed water flows out from the air outlet channel 308.

[0056] It can be understood that: when the charging gun 2 is inserted into the socket 209, the sponge cover 301 can promptly clean and absorb the moisture on the gun head 201 to ensure the dryness of the gun head 201, and when the charging gun 2 is away from the socket 209, the moisture on the sponge cover 301 can be drained in time to ensure the water absorption effect of the sponge cover 301, and the plug-in cavity 212 is connected to the inner cavity of the charging cabinet body 1. The hot air in the inner cavity of the charging cabinet body 1 will be discharged along the air outlet channel 308, and the sponge cover 301 will be dried at the same time to further ensure the water absorption effect of the sponge cover 301.

[0057] A fire extinguishing chamber 4 is also provided in the charging cabinet body 1, and a driving motor 401 is fixedly connected to the bottom of the fire extinguishing chamber 4, a screw rod 402 is fixedly connected to the output shaft of the driving motor 401, a screw rod sleeve 403 is threadedly connected to the screw rod 402, and a jet nozzle 404 is fixedly connected to the screw rod sleeve 403, and a fire extinguisher 405 is fixedly connected to the top of the fire extinguishing chamber 4, and a first solenoid valve port 406 is provided at the bottom of the fire extinguishing chamber 4, and a soft first connecting pipe is connected between the first solenoid valve port 406 and the jet nozzle 404.

[0058] A limiting block 407 is fixedly connected to the outer wall of the jet nozzle 404 , a limiting groove 408 is provided on the inner wall of the fire extinguishing chamber 4 , and the limiting block 407 is slidably connected to the limiting groove 408 .

[0059] A second solenoid valve port 409 is also provided on the top of the fire extinguisher 405 .

[0060] Specifically: when a fire occurs in the charging cabinet body 1, the driving motor 401 drives the screw rod 402 to rotate forward and reverse, thereby driving the screw rod sleeve 403 to move up and down, and the first solenoid valve port 406 is opened, and dry powder is sprayed along the first connecting pipe and the jet nozzle 404 to extinguish the fire inside the charging cabinet body 1;

[0061] See also Figure 8 When a fire occurs at the connection port between the charging gun 2 and the tram, the second solenoid valve port 409 opens, and the second solenoid valve port 409 penetrates the sealing sleeve 211 through the connecting hose 6, so that the dry powder can be directly sprayed to the connection port between the charging gun 2 and the tram, and the fire can be extinguished in time. The fire detection work can be realized by installing an open flame sensor at the corresponding position.

[0062] A solar panel 5 is provided on the top of the charging cabinet body 1 , and the solar panel 5 is used to receive solar energy and input it into the charging cabinet body 1 for energy storage.

[0063] Working principle: When the electric vehicle is fully charged, align the charging gun 2 with the plug interface 209, align the sealing component with the four connecting blocks 207, and then push the charging gun 2 to move toward the plug interface 209. The sealing component pushes the four connecting blocks 207 to expand outward, so that the four sealing blocks 208 enter the corresponding slide grooves 205 respectively, thereby opening the plug interface 209. As the charging gun 2 continues to move, the gun head 201 is inserted into the plug interface 209. After the charging gun 2 enters the plug interface 209, the gun head 201 will be connected with the plug connector 215, and the gun head 201 will squeeze the plug connector 215, so that the plug connector 215 moves to the left. At the same time, the sponge cover 301 can contact the outer periphery of the charging gun 2, so as to wipe and absorb water from the charging gun 2 to ensure the dryness of the charging gun 2.

[0064] On the contrary, after the charging gun 2 is taken out from the plug interface 209, the four sealing blocks 208 are used to seal the plug interface 209, and the elastic sleeve rod 214 is reset and drives the plug connector 215 to move right. The movement of the plug connector 215 will drive the guide rod 306 and the protrusion 307 to move synchronously, thereby pushing the pressure plate 304 to move upward. The pressure plate 304 will open the air outlet channel 308 and squeeze the sponge cover 301. At this time, the rotating motor 302 drives the ring plate 3 and the sponge cover 301 to rotate. The rotation of the sponge cover 301 cooperates with the squeezing effect of the pressure plate 304 to drain the sponge cover 301, so that the sponge cover 301 remains dry and the squeezed water flows out from the air outlet channel 308.

[0065] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
