Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1 To address the technical problems in the background section, the following hydrogen tank bracket for a hydrogen fuel cell vehicle is provided: Combination Figure 1-4As shown, the present invention provides a hydrogen tank bracket for a hydrogen fuel cell vehicle, including a mounting plate 4, which is mounted on the vehicle frame. A hydrogen tank 1 is disposed on the top of the mounting plate 4. Connecting cylinders 2 are fixedly disposed at both ends of the hydrogen tank 1. Two bracket fixing parts 3 are installed on the top surface of the mounting plate 4. Each bracket fixing part 3 is used to fix and clamp the corresponding connecting cylinder 2 to fix the hydrogen tank 1.

[0015] The bracket fixing component 3 includes a mating plate 37, which is installed on the mounting plate 4. Two fixing plates 36 are fixed on the top surface of the mating plate 37, and two adjusting plates 32 are arranged between the two fixing plates 36. A connecting shaft 321 is fixedly installed through each adjusting plate 32, and each connecting shaft 321 is rotatably arranged between the two fixing plates 36. A U-shaped groove is opened at one end of each adjusting plate 32, and a fixing block 311 is movably hinged in each U-shaped groove. An arc-shaped clamping plate 31 is fixed on the opposite surface of the two fixing blocks 311. A U-shaped groove is opened at the other end of each adjusting plate 32, and a connecting block 34 is arranged in each U-shaped groove. An adjusting groove is opened through each connecting block 34, and an adjusting shaft 39 is arranged in each adjusting groove. Each adjusting shaft 39 is installed in the corresponding U-shaped groove, and an adjusting component is arranged between the two connecting blocks 34 and the mating plate 37.

[0016] Two elliptical sliding holes 371 are provided through the mating plate 37. Each elliptical sliding hole 371 is provided with a mounting bolt 35. The mounting bolt 35 is used to detach the mating plate 37 onto the mounting plate 4.

[0017] The adjusting component includes a movable plate 38, which is fixedly connected to two connecting blocks 34. Two rectangular rods 33 are slidably provided through the movable plate 38. The bottom end of each rectangular rod 33 is fixedly connected to a mating plate 37. An adjusting screw 381 is provided between the two rectangular rods 33. The adjusting screw 381 is threaded through the movable plate 38. The bottom end of the adjusting screw 381 is rotatably connected to the mating plate 37. An adjusting nut 382 is fixedly sleeved on the adjusting screw 381.

[0018] Both fixing plates 36 have arc-shaped grooves on their top surfaces, and one of the fixing plates 36 has a through U-shaped notch 361.

[0019] Working principle: Initial preparation stage First, install the mounting plate 4 on the vehicle frame. Then, place the connecting cylinders 2 at both ends of the hydrogen tank 1 between the two pairs of arc-shaped clamping plates 31, and at the same time, place each connecting cylinder 2 in the arc-shaped groove on the top surface of the corresponding two fixing plates 36. In this way, the initial position of the connecting cylinder 2 in the horizontal direction is initially defined, laying a good foundation for the subsequent fixing operation.

[0020] Adjustment and fixing stage Rotating the adjusting nut 382 causes the adjusting screw 381 to rotate. Since the adjusting screw 381 and the moving plate 38 are connected by a thread, the rotation of the adjusting screw 381 causes the moving plate 38 to slide and move up and down along the two rectangular rods 33. The movement of the moving plate 38 causes the two connecting blocks 34 fixed to it to move up and down synchronously. The connecting blocks 34 are provided with adjusting grooves, and the adjusting shaft 39 is in the adjusting grooves. When the connecting blocks 34 move up and down, the adjusting grooves also move up and down synchronously, which causes the adjusting shaft 39 to slide along the adjusting grooves. The sliding of the adjusting shaft 39, under the action of hinge, allows the adjusting plate 32 to be movably hinged along the two fixed plates 36 through the connecting shaft 321. As the adjusting plate 32 rotates, the two adjacent arc-shaped clamping plates 31 will move closer to each other, clamping and fixing the connecting cylinder 2, and finally realizing the installation and fixing of the hydrogen tank 1.

[0021] Detachable design The mating plate 37 is mounted on the mounting plate 4 by mounting bolts 35 and elliptical sliding holes 371. The design of the elliptical sliding holes 371 is ingenious. It allows the mating plate 37 to have a certain positional adjustment space during installation, which facilitates the installation operation. Moreover, this design also allows the bracket fixing parts 3 to be disassembled and replaced according to actual needs, improving the maintainability of the entire bracket.

[0022] Example 2 like Figure 1-4 As shown, based on the above embodiments, this embodiment further provides the following: Each arc-shaped clamping plate 31 has an arc-shaped rubber plate fixedly installed on its inner arc surface, and each arc-shaped rubber plate has several clamping grooves evenly opened.

[0023] In practical use, based on Embodiment 1, if it is necessary to further enhance the practicality of the overall device, the operation is as follows: Since each arc-shaped clamping plate 31 has an arc-shaped rubber plate fixedly installed on its inner arc surface, and each arc-shaped rubber plate has several clamping grooves evenly opened, the arc-shaped rubber plate provides good protection when clamping and fixing the connecting cylinder 2. At the same time, the use of several clamping grooves helps to further increase the stability of clamping and fixing the connecting cylinder 2, thereby further improving the stability of clamping and fixing the hydrogen tank 1.
