[0041] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] With the increasing popularity of new energy sources, hydrogen energy has been widely used, especially with a surge in the number of hydrogen-powered vehicles. According to data, the adoption rate of hydrogen-powered vehicles is rising rapidly.

[0044] Correspondingly, the safety testing procedures for hydrogen refueling vehicles have become increasingly mature. To ensure the safety and efficiency of the refueling process, multiple refueling testing procedures must be performed, including hydrogen leak detection, vehicle identification, and static electricity elimination.

[0045] However, traditional hydrogen refueling testing procedures typically require operators to perform multiple steps in sequence, such as static electricity elimination, checking the inspection and registration information of the on-board hydrogen storage cylinder, and using a portable hydrogen detector to check for hydrogen leaks. In some situations, such as hydrogen refueling stations with high passenger traffic, each step needs to be performed separately, making the whole process cumbersome and time-consuming. This leads to inefficiency in the hydrogen refueling process, affects vehicle traffic efficiency, and increases customer waiting time.

[0046] Furthermore, the existing testing procedures require a high level of standardization and proficiency from operators, with each step strictly adhering to regulations. However, this over-reliance on manual operation increases the possibility of human error. For example, operators might skip a step due to negligence or fatigue, or make mistakes during the operation, all of which could lead to safety hazards.

[0047] Furthermore, in the existing testing process, different testing items require different equipment, and the test results cannot be integrated. This leads to the dispersion of test results, making it difficult to form a comprehensive assessment and intelligent management. The lack of a unified control system makes it difficult for hydrogen refueling stations to monitor and adjust the testing process in real time, and also makes it impossible to automatically adjust the refueling procedure based on the test results, thus affecting the overall operational efficiency and safety.

[0048] In view of this, this application provides a hydrogen refueling detection device and a vehicle hydrogen refueling equipment. The integrated design greatly simplifies the operation steps. The operator only needs to connect the hydrogen refueling detection device to the vehicle's hydrogen refueling connector and start the detection program. The device can automatically complete the purging, gas extraction and detection steps without manual operation, thereby significantly improving the hydrogen refueling efficiency. The integrated design and electrostatic discharge function also enhance the safety and convenience of operation.

[0049] The following is combined with Figures 1 to 3 This application describes a hydrogenation detection apparatus according to a first aspect of the present application.

[0050] refer to Figures 1 to 3 The hydrogen refueling detection device of this application is used in vehicle hydrogen refueling equipment. The hydrogen refueling detection device includes a housing 100 and a connecting device 200. The housing 100 has a gas extraction channel 100a and a mounting channel 100b. The gas extraction channel 100a and the mounting channel 100b are radially spaced along the mounting channel 100b. The gas extraction channel 100a is used to extract gas from the environment around the hydrogen refueling connector 10 of the vehicle for leak detection. This design makes the detection process more direct and efficient.

[0051] The connecting device 200 is provided in the installation channel 100b. The connecting device 200 is used to connect the hydrogen refueling connector 10 of the vehicle. The connecting device 200 defines a purging channel 200a, which is used to purge the area around the hydrogen refueling connector 10.

[0052] Understandably, the connecting device 200 is disposed within the installation channel 100b for connection to the vehicle's hydrogen refueling connector 10. The connecting device 200 internally defines a purging channel 200a, which, after connection, can purge the area surrounding the hydrogen refueling connector 10 to remove any impurities or residual gas, creating favorable conditions for subsequent leak detection.

[0053] At least one of the housing 100 and the connecting device 200 is a conductor to discharge static electricity conducted from the outside to the hydrogenation detection device. In this way, by timely discharge of static electricity conducted from the outside to the hydrogenation detection device, potential safety hazards caused by static electricity accumulation are avoided.

[0054] As can be seen, compared with the traditional hydrogen refueling testing process, the hydrogen refueling testing device of this application greatly simplifies the operation steps through integrated design. The operator only needs to connect the hydrogen refueling testing device to the hydrogen refueling connector 10 of the vehicle and start the testing program. The device can automatically complete the purging, gas extraction and testing steps without manual operation, thus significantly improving the hydrogen refueling efficiency. In addition, the integrated design and electrostatic discharge function enhance the safety and convenience of operation.

[0055] Optionally, the hydrogenation detection device may be designed with an anti-static indicator, such as an alarm that deactivates when static electricity is eliminated.

[0056] In some embodiments, combined with Figures 1 to 3 The housing 100 includes: a main body 110 defining an installation channel 100b extending along the axial direction of the main body 110; and a detection part 120 disposed on the side of the main body 110, wherein an air extraction channel 100a passes through the detection part 120 along the axial direction of the main body 110.

[0057] The main body 110 is the core support structure of the hydrogen refueling detection device, responsible for defining the installation channel 100b. This channel is used for fixing the connecting device 200 and docking with the vehicle hydrogen refueling connector 10. The installation channel 100b extends axially along the main body 110. This design facilitates the operator to quickly and accurately dock the connecting device 200 with the hydrogen refueling connector 10, and also ensures the stability and reliability of the entire hydrogen refueling detection device during use.

[0058] Optionally, the main body 110 may be made of high-strength, corrosion-resistant materials to cope with the harsh environment and conditions that may be encountered during hydrogenation.

[0059] Furthermore, the detection unit 120 is a key component of the hydrogen refueling detection device responsible for leak detection. It extracts gas from the environment surrounding the hydrogen refueling connector 10 through the extraction channel 100a for subsequent detection and analysis. The detection unit 120 is located on the side of the main body 110, and the extraction channel 100a extends through the detection unit 120 along the axial direction of the main body 110. This arrangement allows the extraction channel 100a to directly and efficiently acquire gas samples around the hydrogen refueling connector 10, thereby improving the accuracy and sensitivity of leak detection.

[0060] Optionally, the detection unit 120 may integrate sensors and detection technologies, such as a high-sensitivity hydrogen sensor and an infrared spectrometer, to achieve real-time monitoring and precise location of hydrogen leaks.

[0061] As can be seen, through the clear division between the main body 110 and the detection part 120, operators can more intuitively and quickly complete the installation and commissioning of the hydrogenation detection device, improve the overall performance and ease of operation of the hydrogenation detection device, and thus improve the efficiency of the entire hydrogenation process.

[0062] In some embodiments, combined with Figure 1 and Figure 3 At least a portion of the structure of the housing 100 forms a grip portion 130, which is an electrostatic subconductor and is connected to the destatic device of the vehicle hydrogen refueling equipment.

[0063] The grip part 130 is designed on the housing 100 of the hydrogen detection device for the operator to hold. Optionally, the surface of the grip part 130 can be treated with an anti-slip material to improve the stability of the grip.

[0064] Optionally, the grip portion 130 may be part of the main body portion 110, or the main body portion 110 may be the grip portion 130.

[0065] In addition, the grip unit 130 also undertakes the important task of static electricity discharge, ensuring safety during operation. Specifically, the grip unit 130 is made of a static-dissipative material, which has moderate conductivity and can effectively conduct static charges from the operator to the ground or static electricity eliminator, thereby avoiding potential safety hazards caused by static electricity accumulation.

[0066] By connecting the grip 130 to the static electricity removal device of the vehicle hydrogen refueling equipment, the static charge on the operator's body will be discharged when the operator grips the grip 130, thereby ensuring safety during the hydrogen refueling process.

[0067] It is evident that by introducing the gripping part 130 and realizing the electrostatic discharge function, the operational safety and convenience of the hydrogenation detection device are further improved.

[0068] In some embodiments, combined with Figure 2 The connecting device 200 includes: a first cylindrical member 210 disposed inside the mounting channel 100b, the first cylindrical member 210 being used at least to connect the hydrogenation connector 10; a second cylindrical member 220 disposed inside the first cylindrical member 210, the second cylindrical member 220 being used at least to connect the purging device; the purging channel 200a extends through the first cylindrical member 210 and the second cylindrical member 220 along the axial direction of the main body 110, and the hydrogenation connector 10 is adapted to be inserted into the inner side of the first cylindrical member 210 and the second cylindrical member 220.

[0069] Specifically, the first cylindrical component 210 is the outer structure of the connecting device 200, mainly responsible for the initial docking and fixation with the hydrogen refueling connector 10 of the vehicle. The first cylindrical component 210 is located on the inner side of the installation channel 100b.

[0070] Optionally, the design of the first cylinder body conforms to the shape and size requirements of the hydrogenation connector 10, ensuring that the two can be tightly and securely connected together. Optionally, the first cylinder body 210 can be fixed to the hydrogenation connector 10 by threads, snaps, or other reliable connection methods.

[0071] Optionally, the inner wall of the first cylindrical component 210 may be made of wear-resistant and corrosion-resistant materials to extend its service life.

[0072] Furthermore, the second cylindrical component 220 is located inside the first cylindrical component 210 and is the core part of the connecting device 200. It is mainly responsible for connecting the purging device and forming the purging channel 200a.

[0073] Similar to the first cylinder, the second cylinder may optionally be designed to conform to the shape and size requirements of the hydrogenation connector 10, ensuring a tight and secure connection between the two. Optionally, the second cylinder component 220 may be secured to the hydrogenation connector 10 via threads, snap-fit ​​connections, or other reliable methods.

[0074] Optionally, the inner wall of the second cylindrical component 220 may be made of wear-resistant and corrosion-resistant materials to extend its service life.

[0075] The second cylindrical component 220 has a dedicated interface or channel for connecting a purging device. Exemplarily, the purging device may include components such as a purging gas source, a control valve, and nozzles for supplying purging gas to the area surrounding the hydrogen refueling connector 10.

[0076] The purging channel 200a is an important passage inside the connecting device 200, used to deliver purging gas to the area around the hydrogen refueling connector 10 to remove any impurities or residual gas. The purging channel 200a extends axially through the first cylindrical member 210 and the second cylindrical member 220 along the main body 110, ensuring smooth flow of purging gas around the hydrogen refueling connector 10. Furthermore, the design of the purging channel 200a considers uniform gas distribution and effective purging area to improve purging efficiency. The hydrogen refueling connector 10 is adapted to be inserted into the inner side of the first cylindrical member 210 and the second cylindrical member 220, forming a tight connection with the purging channel 200a. When the purging gas passes through the purging channel 200a, it can act evenly on the area around the hydrogen refueling connector 10.

[0077] It is evident that by optimizing the structure and design of the connecting device 200, efficient delivery and uniform distribution of the purging gas are achieved, improving purging efficiency and quality, and thus enhancing the reliability and efficiency of the hydrogenation detection device.

[0078] Optional, combined Figure 1 The outer casing 100 may also be provided with a purge button 140, and the purge channel 200a may be designed with a valve. The purge button 140 and the valve are configured such that when the purge button 140 is pressed, the valve opens and releases the purge gas to realize the purge action.

[0079] In some embodiments, combined with Figure 1 and Figure 2Both the first cylindrical component 210 and the second cylindrical component 220 are conductors, and both the first cylindrical component 210 and the second cylindrical component 220 extend out of the outer shell 100 to connect with the static elimination device of the vehicle hydrogen refueling equipment; the hydrogen refueling connector 10 is adapted to make conductive contact with at least one of the first cylindrical component 210 and the second cylindrical component 220.

[0080] Specifically, the first cylindrical component 210 and the second cylindrical component 220, as important components of the connecting device 200, are responsible for docking with the hydrogenation connector 10 and forming the purging channel 200a, as well as for electrostatic discharge. To ensure good conductivity, both the first cylindrical component 210 and the second cylindrical component 220 are made of conductive material, which can effectively conduct static charge to the ground or the electrostatic discharge device.

[0081] To facilitate connection with the static eliminator of the vehicle hydrogen refueling equipment, both the first cylindrical component 210 and the second cylindrical component 220 extend a certain distance beyond the outer casing 100. In this way, the operator can easily connect wires or connectors to these cylindrical components to achieve the static discharge function.

[0082] In addition, the hydrogen refueling connector 10 is a key connection point between the vehicle hydrogen refueling equipment and the hydrogen refueling detection device. In order to ensure the continuity of electrostatic discharge, the hydrogen refueling connector 10 needs to form a conductive contact with at least one of the first cylinder component 210 and the second cylinder component 220.

[0083] Optionally, to achieve conductive contact, the surface of the hydrogenation connector 10 may be treated with gold plating, silver plating, or other highly conductive materials.

[0084] Optionally, the portions of the first cylindrical member 210 and the second cylindrical member 220 that contact the hydrogenation connector 10 may also be made of a corresponding conductive material, and the flatness and smoothness of the contact surface should be ensured to reduce contact resistance and improve conductivity.

[0085] As can be seen, the conductor design of the first cylindrical component 210 and the second cylindrical component 220, along with the connection method extending from the outer shell 100, enables rapid and efficient removal of static charge, significantly reducing the risk of electrostatic discharge during operation. The cylindrical component extending from the outer shell 100 allows operators to easily connect to the static eliminator of the vehicle's hydrogen refueling equipment, improving operational convenience and flexibility. This enhanced static discharge function not only improves the safety of the hydrogen refueling detection device but also provides additional safety for operators, thus improving both the static discharge function and operational safety of the hydrogen refueling detection device.

[0086] In some embodiments, combined with Figure 2 The connecting device 200 further includes an insulating member 230 disposed between the first cylindrical member 210 and the second cylindrical member 220, so that the first cylindrical member 210 and the second cylindrical member 220 are mutually insulated.

[0087] The primary function of the insulating element 230 is to provide electrical isolation, ensuring that the first cylindrical element 210 and the second cylindrical element 220 are electrically independent of each other. This helps to prevent current leakage or short circuits caused by accidental contact or malfunction, thereby protecting the safety of operators and equipment.

[0088] Optionally, the insulating component 230 may be made of a material with high insulating properties, such as ceramic, plastic or other non-conductive materials, which have excellent electrical insulation properties and mechanical strength and can withstand high-pressure hydrogen and various stresses during operation.

[0089] The introduction of the insulating component 230 improves the electrical safety of the hydrogenation detection device, effectively preventing the flow of current between the first cylinder component 210 and the second cylinder component 220, thereby avoiding the risk of potential electrical short circuits or electric shocks. In addition, it helps to improve the reliability of the equipment, prevents equipment damage or downtime due to electrical faults, thereby extending the service life of the equipment and reducing maintenance costs.

[0090] In some embodiments, combined with Figure 2 The connecting device 200 further includes: a first support member 240 disposed inside the first cylindrical member 210; a second support member 250 disposed inside the second cylindrical member 220; and a hydrogenation connector 10 inserted and supported inside the first support member 240 and the second support member 250, wherein both the first support member 240 and the second support member 250 are conductors; wherein the first support member 240 is in conductive contact with the first cylindrical member 210, and the second support member 250 is in conductive contact with the second cylindrical member 220.

[0091] The first support member 240 and the second support member 250 are respectively located inside the first cylindrical member 210 and the second cylindrical member 220. Their main function is to support the hydrogen refueling connector 10 and ensure electrical continuity between the hydrogen refueling connector 10 and the cylindrical member.

[0092] Optionally, in order to maintain good conductivity and mechanical strength, both the first support 240 and the second support 250 are made of conductive materials, such as copper, aluminum or other highly conductive metals, which can effectively transmit current while withstanding various stresses and loads during operation.

[0093] The hydrogenation connector 10 is inserted and supported inside the first support member 240 and the second support member 250, which ensures the stability and accuracy of the hydrogenation connector 10 during the docking process and prevents connection failure or leakage caused by shaking or misalignment.

[0094] In addition, conductive contact is formed between the first support member 240 and the first cylindrical member 210, and between the second support member 250 and the second cylindrical member 220. Thus, when the hydrogen refueling connector 10 contacts the support member, it can also form an electrical connection with the cylindrical member, thereby realizing the connection of the two circuits. In this way, the resistance value of the hydrogen refueling connector 10 between the two support members can be detected. If the resistance value is within the preset range, the electrostatic discharge compliance of the hydrogen refueling connector 10 is achieved.

[0095] Thus, by introducing the first support member 240 and the second support member 250, a more stable support is provided for the hydrogen refueling connector 10, enhancing the stability of the connection device 200 and helping to prevent connection failure or leakage due to shaking or misalignment. Furthermore, the conductor design of the support members and their conductive contact with the cylinder ensure the continuity of the electrical connection, facilitate efficient electrostatic discharge, improve the electrical safety of the entire device, and also facilitate the detection of the resistance value of the hydrogen refueling connector 10 to determine whether the electrostatic discharge on the hydrogen refueling connector 10 meets the compliance requirements.

[0096] In some embodiments, combined with Figure 2 At least one of the first support member 240 and the second support member 250 is an elastic member.

[0097] The flexible support can be finely adjusted according to the shape and size of the hydrogenation connector 10, thereby ensuring a tighter fit and support. This adaptability helps prevent connection failure or leakage due to changes in the size of the hydrogenation connector 10 or manufacturing tolerances.

[0098] In addition, during the hydrogen refueling process, the hydrogen refueling connector 10 may be subjected to impact or vibration from the vehicle's hydrogen refueling equipment. The elastic support can effectively absorb these impacts, reduce the impact of vibration on the connection device 200, and thus extend the service life of the equipment.

[0099] By providing additional support and stability, the resilient support helps prevent the hydrogenation connector 10 from wobbling or misaligning during the docking process, helping to ensure the accuracy and reliability of the connection and reducing safety risks caused by poor connection.

[0100] Optionally, to achieve the function of the elastic support, materials with high elasticity, wear resistance, and corrosion resistance can be selected, such as rubber, spring steel, elastic alloys, or other materials with similar properties. It is important to note that the conductivity of the material must also be considered when selecting it to ensure that the elastic support can form an effective electrical connection with the cylindrical component.

[0101] It is evident that by designing at least one of the first support member 240 and the second support member 250 as an elastic member, the adaptability and flexibility of the hydrogenation detection device are further improved, the stability and safety of the hydrogenation connector 10 are enhanced, and a more convenient and reliable operating experience is provided for the operator.

[0102] In some embodiments, combined with Figures 1 to 3 The hydrogen refueling detection device also includes: a first connecting hose 310 for connecting the gas extraction channel 100a and the gas detection device of the vehicle hydrogen refueling equipment.

[0103] The first connecting hose 310 is mainly used to connect the extraction channel 100a and the gas detection device of the vehicle's hydrogen refueling equipment. During the hydrogen refueling process, to ensure safety, it is necessary to detect the gas inside the vehicle's hydrogen refueling equipment. The first connecting hose 310 can safely and efficiently transfer gas samples from the extraction channel 100a to the gas detection device for real-time analysis and monitoring.

[0104] Optionally, the first connecting hose 310 may be made of a highly elastic, abrasion-resistant, and corrosion-resistant material to ensure its reliability and durability during long-term use.

[0105] Optionally, the inner wall of the first connecting hose 310 may be smoothed to reduce resistance during gas flow and improve transmission efficiency.

[0106] Optionally, the first connecting hose 310 needs to have good sealing performance to prevent gas leakage.

[0107] In some embodiments, combined with Figures 1 to 3 The hydrogen refueling detection device also includes a second connecting hose 320 for connecting the purging channel 200a and the purging device of the vehicle hydrogen refueling equipment.

[0108] The second connecting hose 320 is used to connect the purging channel 200a and the purging device of the vehicle hydrogen refueling equipment. Before or after hydrogen refueling, the connection area between the hydrogen refueling connector 10 and the vehicle hydrogen refueling equipment needs to be purged to remove residual impurities and gases. The second connecting hose 320 can safely and efficiently transmit the purging gas to the purging channel 200a, thereby achieving an efficient purging operation.

[0109] Similar to the first connecting hose 310, the second connecting hose 320 may optionally be made of a highly elastic, abrasion-resistant, and corrosion-resistant material to ensure its reliability and durability during long-term use.

[0110] Optionally, the hose has good sealing performance and pressure resistance to ensure safety and reliability during the purging process.

[0111] It is evident that by introducing the first connecting hose 310 and the second connecting hose 320, the functionality and flexibility of the hydrogenation detection device have been significantly improved. The design of the hoses simplifies the operation process and also improves the efficiency and safety of gas detection and purging operations.

[0112] In addition, a second aspect of this application also provides a vehicle hydrogen refueling device, including the hydrogen refueling detection device in any of the above embodiments.

[0113] The vehicle hydrogen refueling equipment provided in this application greatly simplifies the operation steps through the integrated design of the aforementioned hydrogen refueling detection device. The operator only needs to connect the hydrogen refueling detection device to the vehicle's hydrogen refueling connector 10 and start the detection program. The device can automatically complete the purging, gas extraction and other steps without manual operation, thereby significantly improving the hydrogen refueling efficiency. Furthermore, the integrated design and electrostatic discharge function enhance the safety and convenience of operation.
