[0004] During the charging process of an electric bicycle, the charging head needs to be inserted into the charging socket. This process is very simple and anyone can easily complete it. However, anyone passing by can simply unplug the charging head, stopping the charging process. This situation may affect the normal use of the electric bicycle and thus disrupt the user's daily life. Therefore, a snap-on quick-release charging device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a snap-on quick-release charging device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snap-on quick-release charging device, comprising a body and a charging socket, wherein a power cord is connected to the body, and a charging head is connected to the end of the power cord; the charging socket is fixed to an electric vehicle, and the charging socket has mounting holes and mounting slots; a sealing mechanism is installed on the charging head, the sealing mechanism comprising a hollow sealing ring fixedly installed on the charging head and a cylinder fixedly installed inside the charging head; a thrust spring is provided inside the cylinder, a piston is movably installed inside the cylinder, a drive rod is fixedly installed on the piston, a strong magnet is fixedly installed at the end of the drive rod, and a fastening assembly is installed on the charging head.

[0007] Preferably, the sealing mechanism further includes an electromagnet fixedly installed in the mounting hole, a power module connected to the electromagnet, and a connecting pipe between the hollow sealing ring and the cylinder body.

[0008] Preferably, the input terminal of the power module is connected to the power line, and the output terminal of the power module is connected to the electromagnet.

[0009] Preferably, one end of the thrust spring is connected to the bottom of the cylinder, and the other end of the thrust spring is connected to the piston. The hollow sealing ring is connected to the cylinder through a connecting pipe. The strong magnet on the drive rod is aligned with the electromagnet in the mounting hole, and the electromagnet repels the strong magnet after being energized.

[0010] Preferably, the fastening assembly includes a storage slot formed on the charging head and a positioning sleeve fixedly installed on the drive rod. An elastic buckle is installed in the storage slot, and one end of the elastic buckle is fixedly installed in the storage slot. A first wedge block is fixedly installed at the bottom of the elastic buckle, and a second wedge block is fixedly installed on the positioning sleeve.

[0011] Preferably, a movable notch is provided above the mounting hole, through which the second wedge block is movably mounted on the charging head.

[0012] Preferably, the second wedge block is fixedly installed on the drive rod by a positioning sleeve, and the first wedge block and the second wedge block are aligned front and back, and the elastic buckle is retracted into the charging head through the storage groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, after the charging process begins, the electromagnet is activated. The activated electromagnet generates a repulsive force with the strong magnet, which in turn pushes the drive rod forward. The forward movement of the drive rod causes the piston and positioning sleeve to move forward synchronously. The forward movement of the piston causes the gas in the cylinder to be squeezed into the hollow sealing ring, causing the hollow sealing ring to expand further. The expansion of the hollow sealing ring effectively fills the gap between the charging head and the charging socket, thereby preventing rainwater from entering the charging socket and enhancing the waterproof performance of the device during charging.

[0015] In this application, during the forward movement of the positioning sleeve, it drives the second wedge block to move forward synchronously. Subsequently, the forward movement of the second wedge block causes the first wedge block to be lifted. The lifting action of the first wedge block forces the elastic buckle to pop out of the storage slot. The popped-out elastic buckle then locks into the inner wall of the charging socket, thereby ensuring that the charging head cannot be easily pulled out during charging, thus ensuring the stability of the charging process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a snap-on quick-release charging device, including a body 1 and a charging socket 4. A power cord 2 is connected to the body 1, and a charging head 3 is connected to the end of the power cord 2. The charging socket 4 is fixed to the electric vehicle. The charging socket 4 has a mounting hole 301 and a mounting groove 302. A sealing mechanism 5 and a fastening component 6 are installed on the charging head 3. The fastening component 6 can fix the charging head 3 in the charging socket 4, so that the charging head 3 cannot be pulled out by outsiders at will, ensuring the stability of charging. The sealing mechanism 5 can improve the waterproof performance of the device during charging.

[0023] like Figure 2 and Figure 3As shown, the sealing mechanism 5 includes a hollow sealing ring 501 fixedly installed on the charging head 3 and a cylinder 503 fixedly installed inside the charging head 3. A thrust spring 504 is provided inside the cylinder 503, and a piston 505 is movably installed inside the cylinder 503. A drive rod 506 is fixedly installed on the piston 505, and a strong magnet 507 is fixedly installed at the end of the drive rod 506. The sealing mechanism 5 also includes an electromagnet 508 fixedly installed in the mounting hole 301. A power module 509 is connected to the electromagnet 508. A connecting pipe 502 is provided between the hollow sealing ring 501 and the cylinder 503. The input end of the power module 509 is connected to the power line 2, and the output end of the power module 509 is connected to the electromagnet 508.

[0024] Specifically, once the charging process begins, the electromagnet 508 is activated. Once activated, the electromagnet 508 generates a repulsive force with the strong magnet 507. This repulsive force causes the drive rod 506 to move forward, which in turn drives the piston 505 and the positioning sleeve 604 forward. As the piston 505 moves forward, it compresses the gas inside the cylinder 503 and forces it into the hollow sealing ring 501, causing the ring to expand further. This expansion effectively fills and seals any gaps between the charging head 3 and the charging socket 4, preventing rainwater and other external liquids from penetrating the interior of the charging socket 4. This design significantly improves the device's waterproof performance during charging, ensuring the safety and reliability of the charging process.

[0025] like Figure 2 and Figure 4 As shown, the fastening assembly 6 includes a storage slot 601 on the charging head 3 and a positioning sleeve 604 fixedly installed on the drive rod 506. An elastic buckle 602 is installed in the storage slot 601, and one end of the elastic buckle 602 is fixedly installed in the storage slot 601. A first wedge block 603 is fixedly installed at the bottom of the elastic buckle 602. A second wedge block 605 is fixedly installed on the positioning sleeve 604. A movable notch is provided above the mounting hole 301, and the second wedge block 605 is movably installed on the charging head 3 through the movable notch.

[0026] Specifically, when the positioning sleeve 604 begins to move forward, it pulls the second wedge block 605 forward as well. As the second wedge block 605 advances, it applies force to lift the first wedge block 603. Once the first wedge block 603 is lifted, it forces the elastic buckle 602 to pop out of the storage slot 601. After the elastic buckle 602 pops out of the storage slot 601, it securely fastens to the inner wall of the charging socket 4. This design ensures that the charging head 3 cannot be easily pulled out during charging, thus guaranteeing the stability and safety of the charging process.

[0027] Working principle: The power module 509 converts the electrical energy provided by the power cord 2 into the working voltage required by the electromagnet 508, thereby controlling the electromagnet 508 to start during charging. During charging, the charging head 3 is first inserted into the charging socket 4. After the charging head 3 is inserted, charging can begin, and the electromagnet 508 will be activated. Once activated, the electromagnet 508 will repel the strong magnet 507, forcing the drive rod 506 forward. The forward movement of the drive rod 506 will drive the piston 505 and the positioning sleeve 604 forward. When the piston 505 moves forward, it will force the gas in the cylinder 503 into the hollow sealing ring 501, causing the hollow sealing ring 501 to expand further. This expansion will fill the gap between the charging head 3 and the charging socket 4, preventing rainwater from entering the charging socket 4 and improving the waterproof performance of the device during charging. Secondly, when the positioning sleeve 604 moves forward, it will drive the second wedge block 605 forward. When the second wedge block 605 moves forward, it will push up the first wedge block 603. After the first wedge block 603 is pushed up, it will force the elastic buckle 602 to pop out of the storage slot 601. The elastic buckle 602 that pops out of the storage slot 601 will lock tightly on the inner wall of the charging socket 4, so that the charging head 3 cannot be pulled out by outsiders during the charging process, ensuring the stability of charging. After charging is completed, the electromagnet 508 will be de-energized. After the electromagnet 508 is de-energized, the thrust spring 504 will push the piston 505 and the second wedge block 605 to reset, making it convenient for the user to pull out the charging head 3.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
