[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes. Example

[0028] See also Figure 1 to Figure 7 In this embodiment, a vehicle hydrogen refueling device that is convenient for maintenance is provided, including a mounting head 1 and a gas filling head 2. The mounting head 1 is connected to the gas filling head 2. One end of the gas filling head 2 is provided with a gas filling pipe 3. Hydrogen is transported from the gas filling pipe 3 to the mounting head 1 via the gas filling head 2. The gas filling head 2 and the mounting head 1 are designed for easy disassembly, so that they are easy to separate and thus convenient for maintenance;

[0029] In the technical solution of the present application, the end where the mounting head 1 is docked with the gas filling head 2 is sequentially arranged with a sealing groove 11, an elastic component 12 and a magnetic structure A13 from the inside to the outside. Correspondingly, a sealing ring 21, a push rod 22 and a magnetic structure B23 are arranged at the end of the gas filling head 2 close to the mounting head 1. The structures of the two are arranged corresponding to each other and interact with each other. When connected, the sealing ring 21 is inserted into the sealing groove 11 to achieve a sealing effect and avoid gas leakage. At the same time, the push rod 22 will contact the elastic component 12 and compress the elastic component 12, and the magnetic structure B23 is inserted into the magnetic structure A13 to repel each other through magnetic action.

[0030] The magnetic structure A13 has permanent magnetism, and the magnetic structure B23 also has permanent magnetism, so when the installation head 1 and the gas filling head 2 are connected to each other, a large force or a tool is required. When separation is required, only the switch needs to be turned on, so that the two can be quickly separated, which provides convenience for maintenance operations;

[0031] A switch 4 is provided at the upper end of the gas filling head 2. The switch 4 may be a plug-in rod. The gas filling head 2 and the mounting head 1 are respectively provided with corresponding plug-in holes. The plug-in rod may be a bolt, and the plug-in rod may be a threaded hole, etc. The switch 4 may be provided with one, two or more switches as required. Secondly, the switch 4 may also be a clamping mechanism of the background technology, which is used to connect the mounting head 1 with the gas filling head 2. This is the prior art and will not be described in detail.

[0032] Limiting rings 5 ​​are provided on the front and rear sides of the installation head 1. Correspondingly, limiting rods 6 are provided on the front and rear sides of the gas filling head 2. The limiting rods 6 slide in the limiting rings 5. When the gas filling head 2 and the installation head 1 are connected to each other, the limiting rods 6 are first inserted into the limiting rings 5 ​​to achieve the positioning effect, so as to facilitate the installation of the switch.

[0033] The sealing groove 11 includes an inner groove 111 and an outer groove 112. The inner groove 111 is arranged inside the outer groove 112, and the depth of the inner groove 111 is less than that of the outer groove 112. Similarly, the sealing ring 21 includes an inner ring 211 and an outer ring 212. The inner ring 211 is adapted to the inner groove 111, and the outer ring 212 is adapted to the outer groove 112. The design of the above structure achieves a double sealing effect, increases the sealing performance, and avoids hydrogen leakage.

[0034] The elastic component 12 includes a mounting hole 121 and a spring rod 122. A plurality of mounting holes 121 are provided, which are evenly spaced and distributed at the end of the mounting head 1. The spring rod 122 is located in the mounting hole 121. The inner diameter of the mounting hole 121 matches the outer diameter of the push rod 22. When the mounting head 1 is connected to the gas filling head 2, the push rod 22 is inserted into the mounting hole 121 and compresses the spring rod 122.

[0035] The spring rod 122 includes a telescopic rod 1221, one end of the telescopic rod 1221 is fixed to the inner wall of the mounting hole 121, and a moving block 1222 is arranged at the other end thereof, and a spring 1223 is also sleeved on the telescopic rod 1221. After the push rod 22 is inserted into the mounting hole 121, it exerts a force on the moving block 1222, pressing it to make it slide in the mounting hole 121, and compressing the telescopic rod 1221 and the spring 1223, so that the spring 1223 is deformed and has a rebound force. On the contrary, when separated, the magnetic adsorption force disappears, and the moving block 1222 will drive the push rod 22 to move out of the mounting hole 121 under the action of the rebound force of the spring 1223, thereby quickly separating the mounting head 1 from the gas filling head 2, realizing convenient disassembly, and providing convenience for the maintenance of the device.

[0036] The magnetic structure A13 includes a slot 131, in which a first permanent magnet 132 with permanent magnetism is arranged, and the magnetic structure B23 includes an insert ring 231, which is adapted to the slot 131, and an annular groove is arranged at the end of the insert ring 231 and a second permanent magnet 232 is embedded, and the second permanent magnet 232 generates a magnetic field, which can repel the first permanent magnet 132 to separate the installation head 1 from the gas filling head 2. The plug hole can be arranged on the side of the insert ring 231.

[0037] In the hydrogenation device of the utility model, the sealing groove 11 and the sealing ring 21 interact with each other to achieve sealing when the installation head 1 and the filling head 2 are connected to avoid hydrogen leakage; and the magnetic structure A13 with permanent magnetism and the magnetic structure B23 with modifiable magnetism cooperate with each other to achieve rapid separation through the effect of magnetic repulsion, providing convenience for the maintenance of the hydrogenation device.

[0038] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
