[0028] Embodiment 1

[0029] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0030] A metal hydrogen storage vehicle-mounted hydrogen charging and discharging device, comprising:

[0031] A metal hydrogen storage tank body 1;

[0032] A mounting seat 2, the mounting seat 2 is fixedly connected to the lower end of the metal hydrogen storage tank body 1;

[0033] A chute 3, the chute 3 is opened at the lower end of the mounting seat 2, and a slider 4 is slidably connected in the chute 3;

[0034] A threaded groove 5, the threaded groove 5 is opened at the side end of the mounting seat 2, a bolt 6 is threadedly connected in the threaded groove 5, and the bolt 6 is connected to the slider 4;

[0035] A column 7, the column 7 is fixedly connected to the lower end of the slider 4;

[0036] A bottom plate 8, the bottom plate 8 is fixedly connected to the lower end of the column 7, and a mounting groove 9 is opened on the bottom plate 8.

[0037] In a specific embodiment of the present utility model, the metal hydrogen storage tank 1 is the core part of the entire system and is used to store hydrogen adsorbed by the metal hydride. The metal hydride can store hydrogen at a relatively high density, making the on-vehicle application more efficient. The mounting seat 2 is used to fix the metal hydrogen storage tank on a vehicle or other mobile platform to ensure its stability during movement. The chute 3 and the slider 4 allow the metal hydrogen storage tank to move or adjust its position within a certain range. The sliding of the slider in the chute can achieve the horizontal or vertical adjustment of the tank body, facilitating loading and unloading or adapting to different installation requirements. By rotating the position of the bolt 6 in the threaded groove 5, the pressure of the bolt on the slider can be changed, thereby adjusting the position of the metal hydrogen storage tank and fixing it at the desired position. This is a common mechanical locking method to ensure that the tank body does not shift due to vibration during transportation. The upright column 7, as a support member connecting the slider and the bottom plate, provides sufficient strength and stability to ensure the structural safety of the entire device. The bottom plate 8 and the mounting groove 9 The bottom plate is usually used to fix the entire device on the vehicle chassis or other platforms, while the mounting groove facilitates the use of screws or other fasteners to firmly connect the bottom plate to the vehicle, ensuring the stability and safety of the entire device during operation.

[0038] Specifically, please refer to Figures 1-4 , a first four-way switching valve 12 and a second four-way switching valve 13 are provided on the metal hydrogen storage tank 1, and adjusting handles 16 are provided on both the first four-way switching valve 12 and the second four-way switching valve 13.

[0039] In this embodiment: The first four-way switching valve 12 and the second four-way switching valve 13 A four-way switching valve is a type of valve that has four openings and can control the flow of gas through pipes in different directions. In the application scenario of the metal hydrogen storage tank, these valves are mainly used to control the flow direction of hydrogen, such as supplying hydrogen from the hydrogen storage tank to the fuel cell or filling the hydrogen storage tank from an external hydrogen source. The first four-way switching valve may be responsible for the filling process, that is, filling hydrogen from an external hydrogen source into the hydrogen storage tank. The second four-way switching valve may be responsible for the hydrogen release process, that is, transporting the hydrogen in the hydrogen storage tank to the fuel cell or the emission system. The adjusting handle 16 is a device for manually operating the four-way switching valve. By rotating the adjusting handle, the operator can change the channels inside the valve, thereby controlling the flow direction of hydrogen. This provides a direct and intuitive way for the operator to manage the hydrogen filling and release process, ensuring the safety and efficiency of the system operation.

[0040] Specifically, please refer to Figures 1-4 , the side end of the first four-way switching valve 12 is fixedly connected to an eddy current device 11, and the upper end of the eddy current device 11 is connected to a proportional adjustment device 15.

[0041] In this embodiment: The eddy current device 11 is usually used in a gas processing system to increase the path length of the gas flow, thereby increasing the contact time between the gas and the interior of the system. In a metal hydrogen storage system, the eddy current device may be designed for one or more of the following purposes: increasing the contact area and time between hydrogen and the metal hydride to improve the hydrogen adsorption efficiency. During the hydrogen release process, it helps to evenly distribute hydrogen, reduce local pressure fluctuations, and make the hydrogen release process more stable. Promote the mixing of hydrogen molecules, especially when the temperature or pressure changes, to maintain the uniformity of the gas state. The proportional regulating device 15 This device is connected to the upper end of the eddy current device and is used to precisely control the hydrogen flow rate. In applications such as hydrogen fuel cell vehicles, this is crucial because the hydrogen supply needs to match the electrochemical reaction rate of the battery to maintain optimal performance and efficiency. The proportional regulating device can automatically or manually adjust the hydrogen flow rate according to actual needs, ensuring a stable hydrogen supply to the fuel cell while avoiding safety hazards caused by waste or over-supply.

[0042] For details, please refer to Figures 1-4 A connecting pipe 14 is fixedly connected between the eddy current device 11 and the second four-way switching valve 13.

[0043] In this embodiment: The main function of this section of the connecting pipe 14 is to connect the eddy current device 11 and the second four-way switching valve 13 to ensure the smooth flow of hydrogen between the two components. The design of the connecting pipe must consider the pressure resistance, corrosion resistance, and airtightness of the material to ensure the safety and efficiency of the hydrogen transmission process. When hydrogen is released from the hydrogen storage tank, it first passes through the eddy current device 11, and during this process, the hydrogen may be optimized and mixed or homogenized. Subsequently, the hydrogen enters the second four-way switching valve 13 through the connecting pipe 14. The flow rate on the connecting pipe 14 may be affected by the proportional regulating device 15, which means that the hydrogen flow rate can be precisely controlled. In addition, through the adjusting handle 16 on the second four-way switching valve 13, the operator can further adjust the hydrogen flow direction to ensure that the hydrogen distribution meets the system requirements.

[0044] For details, please refer to Figures 1-4 A temperature acquisition port 10 is provided at the front end of the metal hydrogen storage tank 1.

[0045] In this embodiment: The temperature acquisition port 10 allows a sensor to enter the tank to directly measure the temperature of the hydrogen storage material. This helps to understand the working state of the hydrogen storage tank in real time and ensure that the hydrogen storage and release processes are carried out within an appropriate temperature range. The hydrogenation and dehydrogenation reactions of metal hydrides are sensitive to temperature. Too high or too low a temperature may affect the hydrogen storage capacity and may cause safety problems such as abnormal pressure increase. Therefore, continuous temperature monitoring is an important measure to prevent potential hazards.

[0046] For details, please refer to Figures 1-4, the lower ends of the first four-way switching valve 12 and the second four-way switching valve 13 are connected to the metal hydrogen storage tank body 1.

[0047] In this embodiment: The first four-way switching valve 12 is usually responsible for controlling the hydrogen filling process. When it is necessary to replenish hydrogen into the hydrogen storage tank body, the first four-way switching valve will open an appropriate passage to allow hydrogen from an external hydrogen source such as a hydrogen refueling station to enter the hydrogen storage tank body. Precise control of the valve is very important to ensure that hydrogen is filled correctly under a safe pressure. The second four-way switching valve 13 is mainly responsible for the release of hydrogen, that is, supplying hydrogen from the hydrogen storage tank body to a fuel cell or other hydrogen-consuming devices. When hydrogen is needed, the second four-way switching valve will open the corresponding passage to allow hydrogen to flow out of the hydrogen storage tank body for use by the downstream system.

[0048] The working principle and usage process of the present utility model: First, use the combined structure of the chute 3, the slider 4, the threaded groove 5, the bolt 6, the column 7 and the bottom plate 8 to firmly install the metal hydrogen storage tank body 1 on a vehicle or other mobile platform. Ensure that all connections are tightened to adapt to the vibrations and impacts in the mobile environment. Operate the first four-way switching valve 12 by adjusting the handle 16 to make it in the hydrogen filling mode. At this time, the external hydrogen source is communicated with the inside of the hydrogen storage tank body. Hydrogen enters the eddy current device 11 through the connecting pipe 14, where the hydrogen flow passes through the designed eddy current path to optimize the contact between hydrogen and the metal hydride. Then, the hydrogen passes through the proportional regulating device 15 to adjust the flow rate according to the demand to ensure that hydrogen is filled under a safe and effective pressure. During the entire hydrogen filling process, the temperature inside the hydrogen storage tank body is monitored through the temperature acquisition port 10 to ensure that the hydrogen filling process is carried out within an appropriate temperature range to avoid the influence of too high or too low temperature on the hydrogen adsorption capacity of the hydride. Operate the second four-way switching valve 13 by adjusting the handle 16 to switch to the hydrogen release mode. At this time, the inside of the hydrogen storage tank body is communicated with a fuel cell or other hydrogen-consuming devices. Hydrogen is released from the hydrogen storage tank body, and after being evenly distributed by the eddy current device 11, it is transported to the fuel cell or other applications through the connecting pipe 14. The proportional regulating device 15 continues to control the flow rate of hydrogen to match the demand of the hydrogen-consuming device.

[0049] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
