The clamping block 306 is installed in the communication groove 305, which can freely slide between the inner walls of the communication groove 305. The clamping structure is easy to operate, and the position of the clamping block 306 can be accurately controlled by the position adjusting mechanism, realizing quick connection and disassembly. In actual use, the operator can complete the assembly and disassembly of the hydrogen storage tank in a short time, improving the work efficiency. At the same time, the close cooperation of the clamping block 306 and the clamping groove 304 ensures the firmness of the connection, enhances the stability and safety of the hydrogen storage tank during use.

[0035] Further, the position adjusting mechanism includes a bracket 307, which is in a U-shaped structure as a whole, and is detachably connected to the two side surfaces of the base connecting rod 301 through fasteners at both ends. A threaded hole is formed through the inner wall of one side of the bracket 307, and a screw rod 308 is threadedly connected in the threaded hole. One end of the screw rod 308 is rotatably connected to one end surface of the clamping block 306, and the other end of the screw rod 308 is fixedly connected with a knob 309.

[0037] Further, the number of clamping grooves 304 is multiple and uniformly distributed along the extension direction of the tank body connecting rod 302.

[0038] In the actual installation process, according to the use scene and specific needs of the hydrogen storage tank, the knob 309 is rotated to make the clamping block 306 cooperatively connected with the clamping groove 304 at different positions. For example, when the height of the tank body 1 needs to be adjusted to adapt to different installation spaces, the clamping block 306 can be slid into the clamping groove 304 at the corresponding height to realize the adjustment of the relative position of the tank body 1 and the base 2. The design of multiple clamping grooves 304 improves the flexibility of the hydrogen storage tank connection and can meet the diversified requirements for the relative position of the tank body 1 and the base 2 in different use scenes. In the vehicle-mounted hydrogen storage system, the installation position of the hydrogen storage tank can be flexibly adjusted according to the structure and layout of the vehicle; in industrial equipment, it can adapt to different installation conditions, enhancing the universality and applicability of the hydrogen storage tank, so that it can better adapt to various complex installation and use environments.

[0039] Further, each elastic connecting piece includes a telescopic rod 310, the two ends of the telescopic rod 310 are fixedly connected to the side surface of the tank body connecting rod 302 and the side wall of the tank body 1 respectively, a buffer supporting spring 311 is sleeved outside the telescopic rod 310, the two ends of the buffer supporting spring 311 are also fixedly connected to the side surface of the tank body connecting rod 302 and the side wall of the tank body 1 respectively, and a damping structure is arranged inside the telescopic rod 310.

[0040] The telescopic rod 310 is made of high-strength metal material to ensure good telescopic performance and strength. The buffer support spring 311 is sleeved outside the telescopic rod 310, and the two ends of the spring are respectively fixed with the side surface of the tank connecting rod 302 and the side wall of the tank 1 by welding or bolt connection. A damping structure such as damping oil or damping rubber pad is installed inside the telescopic rod 310. In specific operation, a corresponding cavity is opened in the telescopic rod 310, and the damping material is filled therein to achieve the damping effect. When the hydrogen storage tank is subjected to vibration or impact, the telescopic rod 310 telescopes, the buffer support spring 311 is compressed or stretched, and the damping structure consumes energy, thereby playing a buffering and shock-absorbing role and effectively protecting the internal structure and hydrogen storage material of the hydrogen storage tank. The elastic connecting piece effectively improves the anti-shock and anti-impact capability of the hydrogen storage tank and prolongs the service life of the hydrogen storage tank. During vehicle driving, it can effectively buffer the vibration caused by road bumps; in industrial production sites, it can resist the vibration and impact generated by equipment operation, and ensure the safe operation of the hydrogen storage tank in various harsh environments. At the same time, the supporting force provided by the elastic connecting piece enhances the stability of the connection, ensuring that the hydrogen storage tank always maintains a stable state during use.

[0041] Further, the number of elastic connecting pieces between each tank connecting rod 302 and the tank 1 is multiple, and is uniformly distributed along the extension direction of the tank connecting rod 302.

[0042] During installation, the number and distribution spacing of the elastic connecting pieces are reasonably determined according to the length and stress condition of the tank connecting rod 302. For example, in the case of a longer tank connecting rod 302 or greater stress, the number of elastic connecting pieces is appropriately increased. According to the predetermined position, the elastic connecting pieces are respectively installed on the side surface of the tank connecting rod 302 and the side wall of the tank 1, ensuring firm installation and uniform distribution. During installation, the installation angle and position of each elastic connecting piece are strictly controlled to ensure that it can be uniformly stressed and fully play a buffering and shock-absorbing role. The uniform distribution of multiple elastic connecting pieces can more comprehensively withstand external forces, significantly improving the buffering and shock-absorbing effect. When subjected to strong vibration or impact, multiple elastic connecting pieces work together to effectively disperse energy, enhance the stability and reliability of the hydrogen storage tank, and make it adapt to more complex and harsh use environments and working conditions, further ensuring the safety performance of the hydrogen storage tank and providing a strong guarantee for the wide application of the hydrogen storage tank.

[0043] Working principle: the tank body 1 and the base 2 are connected through the quick release connecting assembly 3. The assembly hole 201 at the bottom end of the base 2 is used for installing fasteners to stably fix the hydrogen storage tank on the mounting surface in different scenes. In the quick release connecting assembly 3, the base connecting rod 301 and the tank body connecting rod 302 are preliminarily positioned and slidably connected through the sliding groove 303, and the lengths of the two are consistent to ensure the close connection. The anti-collision guardrails 312 between the base connecting rods 301 can protect the hydrogen storage tank from external collision. In the clamping structure, the knob 309 of the position adjusting mechanism is rotated to drive the screw rod 308, so that the clamping block 306 slides in the communication groove 305 and cooperates with the clamping groove 304 at different positions on the tank body connecting rod 302, thereby realizing the quick connection and separation of the tank body 1 and the base 2, and the relative position of the two can also be adjusted according to the actual requirement. The elastic connecting piece is composed of the telescopic rod 310, the buffer supporting spring 311 and the internal damping structure, and is evenly distributed in multiple between each tank body connecting rod 302 and the tank body 1. When the hydrogen storage tank is subjected to vibration or impact, the elastic connecting piece can play a buffering and damping role, protect the internal structure and hydrogen storage material, enhance the connection stability, and ensure the safe and stable operation of the hydrogen storage tank in complex working conditions and harsh environments.
