[0039] Figure 1 A main structural diagram showing a hydrogen storage bottle fixing device according to an embodiment of the present application; Figure 2 A front view of a fixing clamp 400 of a hydrogen storage bottle fixing device according to an embodiment of the present application is shown; Figure 3 The main structure diagram of the fixing clamp 400 of the hydrogen storage bottle fixing device of the embodiment of the present application is shown. Figure 1 As shown, the hydrogen storage bottle fixing device is characterized in that it includes: a fixing part is arranged on a mounting seat, and the mounting seat is suitable for placing a hydrogen storage bottle 500; the fixing part includes: a first fixing belt 200, a second fixing belt 300 and a fixing clamp 400; one end of the first fixing belt 200 and one end of the second fixing belt 300 are respectively fixed on opposite sides of the mounting seat, and the other end of the first fixing belt 200 is detachably connected to the other end of the second fixing belt 300 through the fixing clamp 400; there are more than two fixing parts, and the more than two fixing parts are arranged adjacent to each other on the mounting seat.

[0040] Here, it should be noted that the hydrogen storage bottle 500 is placed on the mounting seat, the first fixing belt 200 and the second fixing belt 300 are connected to both sides of the mounting seat, and are wrapped around the outer wall of the hydrogen storage bottle 500. By operating the fixing clamp 400, the first fixing belt 200 and the second fixing belt 300 can be fixedly connected and tightened together on the outside of the hydrogen storage bottle 500, and under the joint clamping of the fixing part and the mounting seat, the fixing stability of the hydrogen storage bottle 500 is improved. By operating the fixing clamp 400, the first fixing belt 200 and the second fixing belt 300 can be disconnected to loosen the hydrogen storage bottle 500, so as to facilitate the replacement and maintenance of the hydrogen storage bottle 500. The overall structure of the present application is simple, and the operation process is simple. Under the conditions of severe bumps or emergency braking, the hydrogen storage bottle 500 will not roll or displace under the fixation of the fixing part and the mounting seat, effectively ensuring the normal operation of the vehicle.

[0041] In one possible implementation, the fixing clamp 400 includes: a first connecting nut 420, a second connecting nut, a gasket portion 430 and a bolt 410; the first connecting nut 420 is fixed to one end of the first fixing band 200, and the gasket portion 430 is fixed to one end of the second fixing band 300; the bolt 410 passes through the first connecting nut 420, the gasket portion 430 and is fixedly connected with the second connecting nut. Here, it should be noted that the first connecting nut 420 is suitable for realizing the connection between the bolt 410 and the first fixing belt 200, the gasket part 430 is suitable for realizing the connection between the bolt 410 and the second fixing belt 300, and the second connecting nut matches the bolt 410. After the bolt 410 is inserted into the first connecting nut 420 and the gasket part 430 in sequence, the bolt 410 is fixed and tightened with the second connecting nut to realize the stable connection between the first fixing belt 200 and the second fixing belt 300. The second connecting nut and the bolt 410 are removed to realize the disconnection of the first fixing belt 200 and the second fixing belt 300. The disassembly and assembly process of the fixing clamp 400 is simple and the connection strength is high.

[0042] In a possible implementation, the bolt 410 uses a high-strength 12.9-grade T-bolt. It should be noted that the T-bolt has a higher bolt head strength, which can effectively increase the strength of the bolt 410 and prevent the bolt 410 from being deformed or damaged due to long-term use.

[0043] In a possible implementation, two second connecting nuts are provided; the two second connecting nuts are arranged adjacent to each other. Here, it should be noted that the two second connecting nuts jointly lock the bolt 410, further improving the connection stability of the bolt 410 and preventing the bolt 410 from loosening. As shown in the figure, the two second connecting nuts are respectively a second connecting nut 440 and a second connecting nut 450, and the second connecting nut 440 is located between the second connecting nut 450 and the gasket portion 430. Furthermore, the second connecting nut 440 adopts a conventional hexagonal nut; the second connecting nut 450 adopts a full metal locking nut. The double nut setting can provide a safe connection under low-frequency heavy load conditions, and the full metal locking nut can ensure that the nut does not loosen.

[0044] In one possible implementation, the gasket portion 430 includes: five gaskets; five gaskets are stacked. It should be noted that if the hydrogen storage bottle 500 is heavy, large in volume, and large in size, the setting of a single gasket is prone to gasket deformation during the locking process, resulting in gasket damage and falling off the second fixing belt 300, and insufficient fixing stability of the hydrogen storage bottle 500. A plurality of gaskets are tightly stacked in sequence, which can effectively improve the connection strength of the gasket portion 430, making it difficult to deform, and is beneficial to the fixing stability of the hydrogen storage bottle 500. The corresponding number of gaskets can be flexibly selected according to the different weights, volumes, and sizes of the hydrogen storage bottle 500 to strengthen the connection strength of the fixing clamp 400, and it is also convenient for production line assembly and later product maintenance.

[0045] In a possible implementation, the gasket adopts a conical gasket. It should be noted that the conical gasket has good sealing performance: multiple conical gaskets are stacked, the connection relationship between adjacent conical gaskets is stable, the friction force is large, the fit is high, and the force is uniform, which effectively avoids the deformation of the gasket part 430. At the same time, the conical gasket is usually made of metal or non-metallic materials, has good high temperature resistance and corrosion resistance, and further improves the fixing stability and working reliability of the present application.

[0046] In a possible implementation, the first connection nut 420 is a T-nut. Furthermore, two first clamping portions are protruded from both sides of the T-nut; the two first clamping portions are respectively inserted into both sides of the first bending portion 210 to achieve the connection between the first connection nut 420 and the first fixing belt 200. A circular hole structure is opened in the middle of the T-nut, which is suitable for passing the bolt 410.

[0047] In a possible implementation, two first bending portions 210 are respectively provided at both ends of the first fixing belt 200; one of the first bending portions 210 is fixedly connected to the mounting seat, and the other first bending portion 210 is connected to the first connecting nut 420.

The first bent portion 210 at one end of the first fixing belt 200 is connected to the connecting rod of another placement block 100 in the same way to achieve the connection between the first fixing belt 200 and the mounting seat.

[0052] In a possible implementation, the placement block 100 is provided with a contact portion 110; Figure 1 As shown, the main body of the contact portion 110 is a curved plate-like structure, and the curved surface is suitable for contacting and supporting the hydrogen storage bottle 500.
