[0002] A hydrogen refueling connector is a connecting component between a fuel cell electric vehicle and a hydrogen refueling station for hydrogen refueling. It is mainly used for docking the vehicle with the hydrogen refueling nozzle. During refueling, hydrogen is transferred from the hydrogen refueling station's storage tank to the vehicle's hydrogen storage system via the connector. To improve hydrogen delivery efficiency, a hydrogen refueling connector is needed; however, existing hydrogen refueling connectors still have the following shortcomings:
[0003] When using existing hydrogen refueling connectors, most of them require manual rotation of the connecting pipe to fix the output pipe and the connecting pipe when connecting to equipment such as hydrogen storage tanks or hydrogen fuel cell vehicles. This makes the installation of hydrogen refueling connectors time-consuming and labor-intensive, resulting in reduced practicality and efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug hydrogen refueling connector device, comprising a filling connector and an installation connector. A high-pressure hydrogen refueling valve is installed at the upper end of the filling connector, and an external threaded groove is formed on the outer front end of the filling connector. A protective ring is connected to the outer front end of the filling connector. Installation connectors are distributed at the front end of the filling connector. An installation mating groove is formed at the inner front end of the installation connector, and a receiving groove is formed on the outer side of the installation mating groove. A spring damping rod is installed inside the receiving groove, and a limit ball is installed at the front end of the spring damping rod. An installation mating block is connected inside the installation mating groove, and a limit through hole is formed inside the installation mating block. An installation sealing groove is formed at the inner front end of the filling connector, and a rubber sealing ring is connected inside the installation sealing groove.
[0006] Furthermore, the external dimensions of the filling connector are adapted to the internal dimensions of the protective ring, and the protective ring is rotatably connected to the filling connector through an external threaded groove.
[0007] Furthermore, the outer side of the mounting connector and the outer side of the filling connector are horizontally distributed, and the front end of the mounting connector and the front end of the filling connector are tightly fitted together.
[0008] Furthermore, the internal dimensions of the mounting docking groove are adapted to the external dimensions of the mounting docking block, and the mounting docking block is embeddedly connected to the mounting joint through the mounting docking groove.
[0009] Furthermore, the spring damping rod and the limiting ball are distributed perpendicularly, and the limiting ball is elastically connected to the receiving groove through the spring damping rod.
[0010] Furthermore, the external dimensions of the limiting ball are adapted to the internal dimensions of the limiting through hole, and the limiting ball is connected to the mounting docking block through the limiting through hole.
[0011] Furthermore, the number of limiting balls is set to twelve, and four limiting balls are grouped together, with each group of limiting balls being equidistantly distributed inside the mounting joint.
[0012] Furthermore, the internal dimensions of the mounting sealing groove are adapted to the external dimensions of the rubber sealing ring, and the rubber sealing ring is connected to the filling connector through the mounting sealing groove.
[0013] This utility model provides a quick-plug hydrogen refueling connector device, which has the following advantages:
[0014] 1. This utility model, through the setting of the protective sleeve, enables the control of hydrogen flow and safe isolation by the high-pressure hydrogenation valve during the use of the quick-plug hydrogenation connector device. At the same time, the protective sleeve is rotatably installed on the outside of the filling connector through the external thread groove, protecting the front end of the filling connector from external impacts that could damage the interface. Furthermore, after the filling connector and the installation connector are connected, rotating the protective sleeve allows half of the protective sleeve to be fitted onto the outside of the installation connector, thereby making the connection between the filling connector and the installation connector more secure and improving the overall practicality and efficiency of the hydrogenation connector device.
[0015] 2. This utility model, through the setting of the limiting ball, enables the quick-plug hydrogen refueling connector device to be used. The limiting ball is elastically connected to the receiving groove by the spring damping rod.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 3 As shown, a quick-plug hydrogen refueling connector device includes a filling connector 1 and an installation connector 5. A high-pressure hydrogen refueling valve 2 is installed on the upper end of the filling connector 1, and an external threaded groove 3 is formed on the outer side of the front end of the filling connector 1. A protective ring 4 is connected to the outer front end of the filling connector 1. At the same time, installation connectors 5 are distributed at the front end of the filling connector 1. The external dimensions of the filling connector 1 are adapted to the internal dimensions of the protective ring 4, and the protective ring 4 is rotatably connected to the filling connector 1 through the external threaded groove 3. The outer side of the installation connector 5 is horizontally distributed with the outer side of the filling connector 1, and the front end of the installation connector 5 is tightly fitted with the front end of the filling connector 1. The high-pressure hydrogen refueling valve 2 is fixedly installed on the filling connector 1 by fastening bolts. At the end, the high-pressure hydrogenation valve 2 controls the flow of hydrogen and ensures safe isolation. Meanwhile, the external dimensions of the external threaded groove 3 at the front end of the filling connector 1 are adapted to the internal dimensions of the protective ring 4. Thus, the protective ring 4 is rotatably installed on the outside of the filling connector 1 through the external threaded groove 3. The protective ring 4 protects the front end of the filling connector 1 from external impacts that could damage the interface. After the filling connector 1 is connected to the installation connector 5, the protective ring 4 is rotated so that half of the protective ring 4 is fitted onto the outside of the installation connector 5. This makes the connection between the filling connector 1 and the installation connector 5 more secure, improving the overall practicality and efficiency of the hydrogenation connector device.
[0022] like Figures 1 to 3As shown, the mounting connector 5 has a mounting groove 6 at its front end and a receiving groove 7 on its exterior. A spring damping rod 8 is installed inside the receiving groove 7, and a limit ball 9 is installed at the front end of the spring damping rod 8. A mounting block 10 is connected inside the mounting groove 6, and a limit through hole 11 is provided inside the mounting block 10. A mounting sealing groove 12 is provided at the front end of the filling connector 1, and a rubber sealing ring 13 is connected inside the mounting sealing groove 12. The internal dimensions of the mounting groove 6 are adapted to the external dimensions of the mounting block 10, and the mounting block 10 passes through the mounting groove. 6 is embeddedly connected to the mounting joint 5. The spring damping rod 8 and the limiting ball 9 are vertically distributed, and the limiting ball 9 is elastically connected to the receiving groove 7 through the spring damping rod 8. The external dimensions of the limiting ball 9 are adapted to the internal dimensions of the limiting through hole 11, and the limiting ball 9 is connected to the mounting docking block 10 through the limiting through hole 11. There are twelve limiting balls 9, and four limiting balls 9 are arranged as a group. Each group of limiting balls 9 is equidistantly distributed inside the mounting joint 5. The internal dimensions of the mounting sealing groove 12 are adapted to the external dimensions of the rubber sealing ring 13, and the rubber sealing ring 13 is connected to the filling joint through the mounting sealing groove 12. The head 1 is connected, and the spring damping rod 8 is fixedly installed in the receiving groove 7 opened inside the installation joint 5 by fastening bolts. The limiting ball 9 is fixedly installed at the front end of the spring damping rod 8 with the fastening bolts. The spring damping rod 8 makes the limiting ball 9 elastically connected to the receiving groove 7. The internal dimensions of the installation docking groove 6 opened in the middle of the installation joint 5 are adapted to the external dimensions of the installation docking block 10 set at the front end of the filling joint 1. Thus, the installation docking block 10 is installed into the installation joint 5 through the installation docking groove 6. The internal dimensions of the limiting through hole 11 opened inside the installation docking block 10 are... The installation connector 10 is fixed inside the installation docking groove 6 by the limiting ball 9 and the limiting through hole 11, so that the installation connector 5 and the filling connector 1 can be quickly snapped together. At the same time, the internal dimensions of the installation sealing groove 12 opened at the front end of the filling connector 1 are adapted to the external dimensions of the rubber sealing ring 13 added at the front end of the installation connector 5. Thus, the installation sealing groove 12 and the rubber sealing ring 13 increase the sealing performance after the installation connector 5 and the filling connector 1 are connected, avoid leakage during hydrogen transportation, and improve the overall practicality and efficiency of the hydrogen refueling connector device.
[0023] In summary, this quick-plug hydrogen refueling connector device, during use, firstly controls the flow and safe isolation of hydrogen through the high-pressure hydrogen refueling valve 2. Simultaneously, the protective ring 4 is rotatably installed outside the filling connector 1 via the external threaded groove 3. The protective ring 4 protects the front end of the filling connector 1 from external impacts that could damage the interface. After the filling connector 1 is aligned with the mounting connector 5, rotating the protective ring 4 causes half of it to fit over the outside of the mounting connector 5, thus ensuring a more secure connection between the filling connector 1 and the mounting connector 5. Next, the spring damping rod 8 elastically connects the limiting ball 9 to the receiving groove 7, and the mounting docking groove 6 secures the connector. The mounting block 10 is installed inside the mounting connector 5, and the mounting block 10 is fixed inside the mounting groove 6 by the limiting ball 9 and the limiting through hole 11, so that the mounting connector 5 and the filling connector 1 can be quickly snapped together. At the same time, the sealing groove 12 and the rubber sealing ring 13 are used to increase the sealing performance after the mounting connector 5 and the filling connector 1 are connected, so as to avoid leakage during the hydrogen transportation process. If the hydrogen needs to be transported for a long time, the protective ring sleeve 4 can be rotated and fitted on the outside of the mounting connector 5 and the filling connector 1. If the hydrogen transportation is short-term, the filling connector 1 and the mounting connector 5 can be quickly connected directly, which improves the overall practicality and efficiency of the hydrogen refueling connector device.
