[0030] Please refer to Figures 1 to 6 The purpose of this utility model is to provide a double-sealed and waterproof charging connection device 100. In the charging equipment, the charging equipment can be the charging equipment of a public charging service station or the personal charging equipment of a private parking space, or it can be the charging port of the vehicle body. The charging connection device 100 is used to realize the connection between the charging equipment and the charging gun of the new energy vehicle, so as to charge the new energy vehicle.

[0031] The charging connection device 100 includes:

[0032] The charging socket 10 includes a socket housing 11 for inserting and removing a charging gun and a charging interface 12 located inside the socket housing 11 for electrically connecting the charging gun. A lock hole 13 is provided in the lower part of the socket housing 11 near the charging interface 12.

[0033] A water tank 20 is disposed below the socket housing 11. The water tank 20 includes a water tank housing 21 and a sealing tube 22 located inside the water tank housing 21. The water tank housing 21 is sealed to the socket housing 11 and surrounds the lock hole 13. A through hole 23 corresponding to the lock hole 13 is provided below the water tank housing 21. The lower end of the sealing tube 22 is sealed to the water tank housing 21 around the through hole 23; and...

[0034] An electronic lock 30 is located below the water tank housing 21. The electronic lock 30 includes a lock housing 31 and a locking rod 32 that can move up and down relative to the lock housing 31. The locking rod 32 can pass through the through hole 23, the sealing tube 22 and the lock hole 13 in sequence to enter the socket housing 11. The locking rod 32 is sealed to the upper end of the sealing tube 22.

[0035] In this embodiment, an electronic lock 30 is provided below the charging socket 10. The locking lever 32 of the electronic lock can move into the socket housing 11. This structure meets the NACS North American charging standard. Furthermore, a water collection tank 20 is provided between the electronic lock 30 and the charging socket 10. The locking lever 32 is configured to pass through the water collection tank 20. Simultaneously, the water collection tank 20 has a sealing structure, capable of receiving any water droplets or streams that may appear on the socket housing 11 of the charging socket 10, while preventing water droplets or streams from entering the area where the electronic lock 30 is located. The structure is simple, stable, and has good waterproof performance.

[0036] Furthermore, the sealing tube 22 is configured as a telescopic structure. In this embodiment, the sealing tube 22 is configured as a telescopic structure, with its lower end sealed to the water tank shell 21 and its upper end sealed to the locking rod 32. The telescopic structure of the sealing tube 22 allows the locking rod 32 to maintain a relative seal with the water tank 20 during its up-and-down movement. It can be understood that the sealing tube 22 may not be a telescopic structure; the upper end of the sealing tube 22 can be kept sealed relative to the locking rod 32 by sliding, which is sufficient to prevent water droplets or water flow from passing through.

[0037] Furthermore, the sealing tube 22 is configured as a corrugated tube. In this embodiment, the sealing tube 22 is configured as a corrugated tube structure, which has a good expandable structure and can maintain structural stability even after long-term expansion and contraction.

[0038] It is understood that the sealing tube 22 can also be a rubber tube or a silicone tube. The sealing tube 22 has a certain degree of elasticity, enabling it to expand and contract, and can also meet relevant waterproof requirements.

[0039] Furthermore, the lower periphery of the sealing tube 22 is folded outward to form a sealing rib 221, and the bottom of the water tank shell 21 is provided with a first sealing groove 211 around the through hole 23 to accommodate the sealing rib 221. In this embodiment, by setting the matching structure of the sealing rib 221 and the first sealing groove 211, the sealing connection structure between the sealing tube 22 and the water tank shell 21 is strengthened, which can further improve the waterproof effect.

[0040] Specifically, the bottom of the water tank shell 21 is provided with a connecting ring 212 surrounding the through hole 23. The connecting ring 212 and the bottom of the water tank shell 21 form the first sealing groove 211, and the first sealing groove 211 fixes the sealing tube 22 by welding or snap-fitting. It can be understood that the water tank shell 21 and the connecting ring 212 can also be integrally formed, so that the first sealing groove 211 and the sealing rib 221 are correspondingly sealed and connected.

[0041] Furthermore, a sealing ring 222 is formed near the lower periphery of the sealing tube 22, which is in sealing connection with the locking rod 32. In this embodiment, an additional sealing connection is added between the lower end of the sealing tube 22 and the locking rod 32, further enhancing the sealing effect of the overall structure. This sealing connection is a sliding friction sealing connection.

[0042] Furthermore, the upper periphery of the sealing tube 22 extends inward to form a sealing band 223, and the locking rod 32 is provided with a second sealing groove 321 corresponding to and sealingly receiving the sealing band 223. In this embodiment, the upper end of the sealing tube 22 is used to prevent water droplets or water flow from flowing along the wall of the locking rod 32. The matching structure of the sealing band 223 and the second sealing groove 321 further achieves the blocking of water droplets or water flow, and at the same time, it can also enhance the structural stability of the sealing tube 22 and the locking rod 32.

[0043] Furthermore, the water receiving tank 20 also includes a drain pipe 24, which connects to the outside from the bottom of the water tank shell 21. In this embodiment, the water receiving tank 20 discharges water from the water tank shell 21 to the outside through the drain pipe 24, preventing water accumulation.

[0044] Furthermore, a sealing ring 40 is provided between the connection structure of the water tank housing 21 and the socket housing 11. Specifically, the sealing ring 40 is an irregularly shaped sealing ring adapted to the interface shape of the connection part between the water tank housing 21 and the socket housing 11.

[0045] Furthermore, the electronic lock 30 also includes a driver 33, which is disposed within the lock housing 31 and is used to drive the locking rod 32 to move.

[0046] In one embodiment, the lower periphery of the sealing tube 22 is folded outward to form a sealing rib 221, and the bottom of the water tank shell 21 is provided with a first sealing groove 211 corresponding to receiving the sealing rib 221 around the through hole 23; the upper periphery of the sealing tube 22 extends inward to form a sealing band 223, and the locking rod 32 is provided with a second sealing groove 321 corresponding to sealing and receiving the sealing band 223; the upper end of the sealing tube 22 is sealed to the locking rod 32, and the lower end of the sealing tube 22 is sealed to the bottom of the water tank shell 21. In this embodiment, by setting the sealing tube 22 and sealing its upper and lower ends to the locking rod 32 and the water tank shell 21 respectively, the charging socket 10 and the electronic lock 30 are sealed together.

[0047] Secondly, this utility model embodiment also provides a charging device, including the charging connection device described above and a power supply device electrically connected to the charging interface. The power supply device is connected to mains power or industrial power, and outputs electrical energy to the new energy vehicle through the charging connection device and the charging gun.
