[0029] The specific embodiments of the present application have been shown in the above figures, and will be described in more detail hereinafter. These figures and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0030] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to any embodiment of the application, unless specified otherwise. It should be understood that every embodiment need not necessarily include all of the features shown in the drawings or all of the components described in the description. The following exemplary embodiments are described herein with reference to the figures, in which like reference numerals refer to like elements throughout the figures.

[0031] The hydrogen filling port plays a crucial role in hydrogen storage system vehicles, not only in terms of the convenience and safety of hydrogen refueling, but also in relation to the overall performance of the vehicle, regulatory compliance, and the promotion of technological innovation. Therefore, during the research and development and production of hydrogen fuel cell vehicles, great attention needs to be paid to the design and optimization of the hydrogen filling port.

[0032] The current design of the hydrogen filling system has the following problems:

[0033] 1. The hydrogen filling port cover is exposed to the outside for a long time, which can easily contaminate with water, dust, and other impurities, reducing the service life. After the hydrogen filling port cover is contaminated with impurities, the impurities may fall into the hydrogen filling pipeline during the taking and placing, thereby affecting safety.

[0034] 2. The hydrogen filling port cover used now mostly protrudes outward when opened, which may cause injury to people outside the vehicle.

[0035] 3. The statistics on the number of hydrogen refueling operations are incomplete. The calculation is based solely on the number of times the hydrogen refueling compartment door is opened, which is not accurate enough.

[0036] 4. The safety features for hydrogen refueling are inadequate. The vehicle can be moved while refueling, which could pose a safety hazard.

[0037] To address the above issues, this patent proposes a hydrogen storage system in which the hydrogen refueling port is located on a lifting device and is concealed when not refueling. When refueling is needed, the port rises to expose the refueling port for easy access. This prevents the refueling port cap from being exposed for extended periods, increasing its lifespan, reducing the likelihood of it becoming contaminated, and enhancing safety. Furthermore, the concealed design of the refueling port and the multiple ways to open the cap minimize the potential for it to protrude outwards and pose a safety hazard.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram of the structure of a hydrogen storage system according to Embodiment 1 of this application, as shown below. Figure 1 As shown, the hydrogen storage system includes:

[0040] High-pressure hydrogen storage cylinder assembly and hydrogen filling port device.

[0041] High-pressure hydrogen storage cylinders are the main equipment for storing hydrogen. They are typically used for high-pressure hydrogen storage and are connected to a hydrogen filling port device via a hydrogen filling pipeline.

[0042] The hydrogen filling port device includes a hydrogen filling port, a hydrogen filling port seat, an electrostatic block, a slider, and a lifting device;

[0043] The hydrogen filling port and the electrostatic block are integrated on the hydrogen filling port holder;

[0044] The hydrogen filling port is connected to the slider, which is mounted on the lifting device. The lifting of the lifting device causes the hydrogen filling port to move.

[0045] The hydrogen filling port holder supports the hydrogen filling port and other components, and ensures that the hydrogen filling port can be moved or repositioned when needed.

[0046] Static electricity blocks are used to prevent the accumulation of static electricity, especially during hydrogenation, where static electricity can cause safety issues. The static electricity blocks discharge charge through grounding, ensuring safety during hydrogenation.

[0047] The lifting device drives the lifting of the hydrogen inlet through the movement of the sliding block, realizes the hiding and exposure of the hydrogen inlet, and can also adjust the height of the hydrogen inlet to adapt to the hydrogenation requirements of different heights or angles, facilitating efficient hydrogenation operation.

[0048] The hydrogen inlet is connected with the hydrogenation pipeline of the high-pressure hydrogen storage bottle group through a hydrogen hose. The hydrogen hose has a reserved movable length. The hydrogen hose provides flexibility and mobility and has a certain movable length. When the hydrogen inlet moves up and down, the normal connection of the hydrogenation pipeline can be ensured. Even if the position of the hydrogen inlet changes, the hydrogen hose can still work normally.

[0049] In summary, the hydrogen storage system provided by the application realizes the hiding and exposure of the hydrogen inlet by driving the hydrogen inlet to move up and down through the lifting device during hydrogenation operation, so that the hydrogen inlet cover is not exposed outside for a long time, the service life of the hydrogen inlet cover is increased, the probability of the hydrogen inlet cover being contaminated by foreign matter is reduced, and safety is increased. The static block on the hydrogen inlet seat ensures that static electricity is safely guided during operation to prevent electric sparks or other hazards. Through the design of the sliding block and the lifting device, the entire hydrogen inlet device has high flexibility and can adjust the position and height of the hydrogen inlet according to actual needs.

[0050] In a specific implementation manner, Figure 2 For the structure diagram of a second embodiment of the hydrogen storage system provided by the application, refer to Figure 2 As shown in the figure, the lifting device includes a motor and a lead screw. The sliding block is arranged on the track of the lead screw. When the motor rotates, the sliding block is driven to move by the lead screw.

[0051] In addition to the design of using a motor and a lead screw, the lifting device can also use several other different ways to realize up and down movement. The specific design depends on the requirements of the application scene:

[0052] Hydraulic lifting device, the hydraulic lifting device provides lifting force through a hydraulic system. The hydraulic cylinder is connected with the hydraulic pump. The flow and pressure of the hydraulic fluid are controlled to drive the piston to move up and down, thereby driving the lifting of the sliding block.

[0053] Chain or belt driven lifting device, the motor drives the chain or belt to rotate through a gear, and the chain or belt drives the sliding block to move up and down. This way transmits power from the motor to the sliding block through a transmission device.

[0054] Servo motor + ball screw lifting device, the servo motor realizes precise lifting control through a ball screw transmission mechanism. The ball screw has higher efficiency and precision than the traditional lead screw.

[0055] Magnetic lifting device, which uses the force of an electromagnet to lift. It is usually used in non-contact lifting systems to avoid mechanical wear and tear.

[0056] The lifting device can move the hydrogen filling port, which can be exposed or hidden in the skin, achieving an aesthetic effect. In addition, the lifting device is also provided with a track, which can ensure the stability of the sliding block and stop at different positions during sliding, achieving the adjustment of the hydrogen filling port at different heights.

[0057] In addition, the hydrogen filling port can be stopped when it is confirmed to be returned to the position (safety setting) through the travel switch. In order to ensure the movement of the hydrogen filling port, the pipeline connected to the rear end of the hydrogen filling port is designed as a high-pressure hydrogen hose. The hydrogen filling port can be stopped at different heights to adapt to the operation of the hydrogen filling gun by people of different heights.

[0058] If the lifting device is controlled by a motor, the motor is connected with a hydrogen filling switch outside the vehicle. In this way, when hydrogenation is needed, the hydrogen filling personnel press the hydrogen filling switch to expose the hydrogen filling port, and click the hydrogen filling switch again to hide the hydrogen filling port after hydrogenation is completed.

[0059] In one way, the motor is directly connected with the external hydrogen filling switch.

[0060] In another way, the hydrogen filling switch is connected with the motor through the hydrogen storage system controller. When hydrogenation is needed, the hydrogen storage system controller receives the signal of the hydrogen filling switch, judges the state of the vehicle, and controls the motor to work when the hydrogenation condition is met.

[0061] After the motor is connected with the hydrogen storage system controller, the user can control the motor through the display screen in the vehicle through internal communication. The vehicle key can also send a hydrogenation signal to the vehicle controller, and then control the hydrogen filling port to be exposed through the hydrogen storage system controller.

[0062] Optionally, the hydrogen storage system further comprises an infrared receiver arranged in a preset range outside the skin of the hydrogen filling port.

[0063] Currently, 70MPA hydrogen filling guns are equipped with infrared communication for transmitting temperature signals, while most 35MPA hydrogen filling guns are not equipped with infrared communication. If the hydrogen filling gun is equipped with infrared communication, an infrared receiver is added beside the hydrogen filling port, which is connected with the motor and / or the hydrogen storage system controller. In this way, when the hydrogen filling gun approaches, the hydrogen filling port can be automatically exposed after the vehicle is powered off.

[0064] In the above manner, the hydrogen filling port can be exposed or hidden through buttons, infrared communication, vehicle keys, and vehicle screens. The buttons are in a manual mode, and the infrared communication is in an automatic mode, which can realize manual and automatic exposure / hiding of the hydrogen filling port. This can be realized whether the hydrogen filling gun has infrared communication or not. The buttons are arranged on the hydrogen storage system skin and can be operated after power-off to avoid theft and accidental touch in the unlocked state.

[0065] Figure 3 Figure 3 is a structural schematic diagram of a third embodiment of a hydrogen storage system of the present application. Figure 3 .

[0066] The high-pressure hydrogen storage cylinder group includes multiple cylinders for storing high-pressure hydrogen gas to be used as fuel for a fuel cell engine to convert chemical energy into electrical energy. Each cylinder is provided with a corresponding cylinder valve, which are connected in series. After the cylinder valves, an integrated pressure reducing valve is centrally provided for more accurate and rapid pressure control.

[0067] Further, a pressure sensor is provided in the cylinder valve corresponding to the top cylinder of the high-pressure hydrogen storage cylinder group, which is connected to the hydrogen storage system controller. The pressure sensor is used to detect pressure changes during hydrogen filling. Hydrogen is lighter than air, so the pressure change of the upper cylinder is relatively obvious among multiple cylinders, which can accurately reflect the hydrogen filling change. Therefore, the pressure sensor needs to be provided in the cylinder valve corresponding to the top cylinder.

[0068] When the hydrogen pressure rises by more than 5mpa, it is determined that hydrogen filling is successful, which is counted as one hydrogen filling. This method can effectively improve the convenience of hydrogen filling and is more accurate than simply counting the number of times the hydrogen filling hatch is opened.

[0069] Further, the cylinder valve is integrated with a solenoid valve, a check valve, a thermal fuse valve, a manual valve, a medium inlet and outlet, and a pressure sensor mechanical interface.

[0070] In Figure 4 , only the internal structure of one cylinder valve is shown, and the structures of other cylinder valves are similar to that of the cylinder valve.

[0071] The function of the thermal fuse valve is to ensure that when a fuel cell vehicle encounters a fire, it can automatically melt at high temperatures, quickly release the high-pressure hydrogen gas in the on-board hydrogen cylinder, and avoid explosion accidents caused by overpressure due to heating of the on-board hydrogen cylinder.

[0072] The cylinder valve is provided with a manual valve to ensure the independence of each on-board hydrogen storage cylinder. It is normally in an open state, and when a hydrogen storage cylinder needs to be repaired or replaced due to some reason, the manual valve can be closed without affecting the normal operation of the entire hydrogen system. The function of the manual valve is to replace the solenoid valve when it fails.

[0073] Further, the hydrogen supply pipeline refers to the hydrogen flowing into the filter through the integrated bottle valve, being reduced in pressure by the integrated pressure reducing valve, being reduced to the required pressure of the fuel cell, and the outlet end of the pressure reducing valve being provided with a pressure sensor and a safety valve (i.e. a low-pressure venting needle valve). Pressure abnormalities are protected by the integrated bottle valve internal solenoid valve and the battery valve after pressure reduction. The solenoid valve in the integrated pressure reducing valve is the switch of the entire hydrogen supply pipeline. When the fuel cell vehicle is "ignited", it is automatically opened to supply hydrogen to the fuel cell engine. When the vehicle is "turned off", it is automatically closed to stop hydrogen supply.

[0074] The high-pressure hydrogen from the on-board hydrogen cylinder is adjusted to the low-pressure hydrogen required by the fuel cell engine through the pressure reducing valve in the integrated pressure reducing valve, and the output hydrogen pressure can be kept stable in the rapid change of hydrogen flow demand. The integrated pressure reducing valve integrates a check valve, a filter, a multi-stage pressure reducing device, an electromagnetic cut-off valve at the front end of the inlet, and a pressure sensor interface and a safety valve interface at the outlet of the valve body. Among them, the check valve is to avoid the influence of reverse pressure impact on the valve core life, and the filter is to filter the impurities in the gas to avoid the influence of impurities entering the valve body on its life. The pressure sensor reflects the output hydrogen pressure value. The safety valve functions to limit the flow of hydrogen in the pipeline until the flow is cut off when the downstream pipeline hydrogen flow suddenly increases due to an accident.

[0075] Further, the pipeline between the hydrogen hose and the bottle valve is the hydrogen filling pipeline, which is connected with a check valve, a filter, a pressure sensor, and a solenoid valve. The hydrogen filling port is connected with a hydrogen filling gun of a hydrogen filling station, and the on-board high-pressure hydrogen storage cylinder group is filled with hydrogen through the hydrogen filling hose and the hydrogen filling pipeline. The check valve end can also be connected with an electromagnetic valve for preventing overpressure and a pressure sensor for detecting overpressure (not shown in the sensor diagram). The standard hydrogen filling port facilitates safe and rapid connection with the hydrogen filling gun of the hydrogen filling station. The filter can block small dust particles accidentally brought in during the hydrogen filling process. The check valve can prevent the high-pressure hydrogen of the hydrogen storage cylinder from flowing back, which may flow into the hydrogen filling machine in some cases (such as when the pressure of the low-pressure hydrogen storage cylinder of the hydrogen filling station is lower than that of the on-board hydrogen storage cylinder). The solenoid valve can prevent overpressure danger caused by accidental loss of control of the hydrogen filling machine, ensuring that the on-board hydrogen storage cylinder will not bear a safety pressure exceeding its design. At the same time, if there is a risk of hydrogen leakage at the hydrogen filling port, the hydrogen filling can be cut off in time to ensure safety.

[0076] A temperature sensor can be installed in the bottle valve of the hydrogen storage system, and the system can monitor and control the temperature of each part in real time.

[0077] Multiple pressure sensors can be installed at key positions of the hydrogen storage system (inside the cylinder and after pressure reduction) to monitor the pressure changes of each component in real time.

[0078] The venting pipeline is divided into two routes, one of which is connected with the fuse valve, in order to reduce the resistance when hydrogen is rapidly discharged, a relatively thick pipe diameter and a relatively large bending radius are selected, the end of the pipeline is led to a safe place outside the carriage, and a soft plug is provided to prevent foreign matter from falling into the pipeline and causing blockage, at the same time, when the fuse valve is opened due to heat, the high-pressure hydrogen gas in the pipeline can easily flush the plug and be rapidly discharged; the other route is connected with the hydrogen supply pipeline safety valve and the venting end of the low-pressure pipeline.

[0079] A plurality of leakage detection instruments are arranged above the high-pressure hydrogen storage bottle group and the hydrogen supply pipeline, and can be arranged above the gas bottle mouth, the bottle tail and the hydrogen filling port to monitor the leakage in the hydrogen storage system in real time. Through multi-point monitoring, the accuracy and coverage of leakage detection are improved. Since the weight of hydrogen is lower than that of air, the leaked gas is upward, so the leakage detection is arranged above to accurately detect the positions prone to leakage.

[0080] The leakage detection instrument can be directly connected with the pipeline. Through the connection with the pipeline, the detector can detect the gas or liquid leakage in the pipeline, so as to accurately judge the occurrence of leakage. In addition, the leakage detection instrument can also be directly installed above the pipeline without direct connection with the pipeline, so as to detect the gas leaked from the pipeline. Since the gas usually diffuses upward, the detector arranged above the pipeline can more easily capture the leaked gas.

[0081] The temperature and pressure signals are transmitted to the vehicle controller to help monitor the consumption of on-board hydrogen, so as to remind the driver to timely add fuel.

[0082] In summary, the electromagnetic valve and the hydrogen leakage detection instrument are arranged at the hydrogen filling port to increase the safety of the hydrogen filling port. By designing the hydrogen filling device, the display of the hydrogen filling port is hidden, and the hydrogen filling port is exposed or hidden through multiple ways. The hydrogen filling port is set with a travel switch to monitor the retraction state. By optimizing the hydrogen filling process of the vehicle hydrogen supply system, hydrogen filling operation can be performed only when the vehicle is powered off and unlocked. When the hydrogen filling port is exposed, the hydrogen pressure rises by more than 5mpa, which means that the hydrogen filling is successful. If the hydrogen filling port is not retracted, it means that the hydrogen filling is still in progress, and the vehicle cannot be driven at this time. The vehicle can be locked normally only when the vehicle doors are all locked, the vehicle is in P gear, and the hydrogen filling port is retracted normally. This method can effectively improve the hydrogen filling convenience, accurately count the number of hydrogen filling, increase the safety of the hydrogen filling port, reduce the risk of explosion caused by hydrogen leakage, reduce the harm, and enhance the safety of the vehicle in use.

[0083] Figure 4 The connection diagram of the hydrogen storage system provided in the present application is as follows, Figure 4As shown, the hydrogen storage system controller is mainly used for processing sensor signals, controlling the action of electromagnetic valves, communicating data with the fuel and electric system controller and the vehicle controller through CAN, and powering all devices. The fuel and electric system controller is connected with the instrument panel through CAN bus, transmits alarm information to the instrument panel, and displays it on the instrument panel. Among them, the sensor signals are mainly composed of pressure sensors, concentration sensors, bottle valve temperature sensors, travel switches, etc., and are mainly used for signal detection and feedback. The electromagnetic valve mainly controls the opening and closing of the bottle valve and the pressure reducing valve to control the on-off of the pipeline, meeting the demand of vehicle operation for gas supply.

[0084] In the actual hydrogenation process of the above hydrogen storage system, first, the vehicle state is confirmed to ensure that the vehicle is in the powered-off and unlocked state, and the hydrogenation operation can be performed (ensure that the four doors of the vehicle are closed, and confirm that the vehicle is in P gear). Through key remote control or buttons or display screens or infrared communication, the hydrogenation port can be operated to descend and display the hydrogenation port. After the hydrogenation port is exposed, the hydrogen pressure rises by more than 5mpa (to avoid misjudgment due to changes in ambient temperature), that is, the hydrogenation frequency +1 is determined. If the hydrogenation port is not retracted, it means that it is still in the hydrogenation process, and at this time, the vehicle cannot be driven. After the hydrogenation is completed, the hydrogen pressure and the hydrogenation frequency are displayed on the screen in the cab, and the travel switch judges that the retraction is successful, and the vehicle can be driven online. The real-time pressure monitoring and feedback mechanism of the hydrogenation system ensures the smooth progress of the hydrogen refueling process, and effectively prevents the driving safety problem caused by incomplete hydrogenation through the vehicle control system. Through accurate hydrogenation control and intelligent vehicle management, this system can greatly improve the safety and convenience of hydrogenation operation.
