[0002] In fields such as hydrogen-powered vertical takeoff and landing (VTOL) aircraft, securing hydrogen cylinders is a crucial aspect of ensuring flight safety and performance. Traditional hydrogen cylinder securing structures have several drawbacks. Firstly, the installation and disassembly processes are cumbersome and complex, often requiring multiple tools and consuming significant time and manpower, severely impacting work efficiency, especially in scenarios requiring rapid cylinder replacement. Secondly, they offer insufficient protection for the cylinders. During installation, the friction between the cylinder and the securing structure is substantial, easily scratching the cylinder surface, compromising its structural integrity, and shortening its lifespan. Furthermore, traditional structures lack stability in securing cylinders under dynamic loads, allowing for significant displacement and swaying, affecting the aircraft's balance and safety.

[0003] Based on this, this utility model proposes a quick-release fixing structure for hydrogen-powered vertical lifting gas cylinders, aiming to solve the technical problems of inconvenient installation and disassembly, poor protection of gas cylinders, and unstable dynamic fixing of traditional fixing structures, and to achieve a balance between safety and ease of operation.

Detailed Implementation

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0019] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with reference to specific embodiments: A quick-release fixing structure for a hydrogen-powered vertically mounted gas cylinder, referenced. Figure 1 , 2 3. It includes an installation compartment 1, which is equipped with multiple fixing frames 2. The surface of the fixing frame 2 is provided with a channel for the hydrogen cylinder to pass through. The channel size is larger than the size of the hydrogen cylinder body. The installation compartment 1 is equipped with a limit frame 3, which is located outside the fixing frame 2. The surface of the limit frame 3 is provided with a fixing hole. The size of the fixing hole is larger than the size of the front end of the hydrogen cylinder. The front end of the gas cylinder is inserted into the fixing hole on the surface of the limit frame 3.

[0020] 1. The first fixed frame 2 in the inlet direction of the installation compartment is detachable and has a fixing strap 4.

[0021] The hydrogen cylinder is gradually inserted into the installation chamber 1 through the opening. The front end of the cylinder is inserted into the fixing hole, which keeps the front end of the cylinder in a fixed position. The rear end of the hydrogen cylinder is fixed by the fixing strap 4.

[0022] refer to Figure 2 , 3The fixing strap 4 includes an annular strap 41 and multiple strip straps 42. One end of the strip strap 42 is fixed to the surface of the annular strap 41, and the other end is detachably connected to the surface of the fixing frame 2.

[0023] The design of the fixing strap 4 makes the installation and removal of gas cylinders very convenient. One end of the strip strap 42 is fixed to the surface of the ring strap 41, and the other end is detachably connected to the hook hole and hook groove on the surface of the fixing frame 2 via a hook. When installing the gas cylinder, simply insert the front end of the gas cylinder into the fixing hole of the limiting frame 3, and then pass the hook of the fixing strap 4 through the hook hole and snap it into the hook groove to complete the fixation; when removing, simply remove the hook from the hook groove to easily remove the gas cylinder, greatly saving installation and removal time and improving work efficiency.

[0024] refer to Figure 4 , 5 6, 7. The fixing holes are circular holes, and the area of ​​the fixing holes is 70-80% of the cross-section of the hydrogen cylinder.

[0025] The inner ring area of ​​the annular strap 41 is 60-70% of the cross-section of the hydrogen cylinder.

[0026] The above-mentioned size design ensures that the fixing hole and the ring strap 41 have sufficient fixing effect on the gas cylinder, and also facilitates the insertion and removal of the gas cylinder. It will not cause installation difficulties due to the size being too small, nor will it fail to effectively fix the gas cylinder due to the size being too large, which reflects the scientific and rational nature of the structural design.

[0027] refer to Figure 9 The end of the ring strap 41 that is not connected to the ring strap 41 is provided with a hook 43. The surface of the fixing frame 2 is provided with a hook hole and a hook groove is provided on the edge of the hook hole. The front end of the hook 43 passes through the hook hole and is inserted into the hook groove.

[0028] The channel of the fixed frame 2 is equipped with a pulley assembly.

[0029] There are at least three pulley assemblies. The pulley assembly includes a mounting base 51 and a pulley 52. ​​The mounting base 51 is fixed to the surface of the fixed frame 2, and the pulley 52 is mounted on the mounting base 51. The pulley 52 is located inside the channel.

[0030] refer to Figure 8 The mounting bracket 2 has at least three sets of pulley assemblies in its channel. Each pulley assembly includes a mounting base 51 and pulleys 52, with the pulleys 52 located inside the channel. During gas cylinder installation, the cylinder moves within the channel. The pulleys 52 reduce friction between the cylinder and the mounting bracket 2, preventing scratches on the cylinder surface, protecting its appearance and structural integrity, and extending its service life. Simultaneously, the pulleys 52 also make the cylinder installation process smoother and reduce installation difficulty.

[0031] This utility model provides a quick-release fixing structure for a hydrogen-powered vertical lifting cylinder. The operation is as follows: During operation, the hydrogen cylinder is first smoothly pushed into the channel of the fixing frame 2 until its front end is precisely inserted into the fixing hole of the limiting frame 3 for axial positioning. Then, the annular strap 41 is tightened around the tail of the cylinder, and the hook of the strip strap 42 is inserted into the hook hole of the fixing frame 2 and engaged in the hook groove. Radial fixing is achieved by tightening the strap. For disassembly, simply press the hook to release the fixing strap 4, and the cylinder can easily slide out using the pulley 52 on the fixing frame 2. In the working state, the limiting frame 3 effectively suppresses axial displacement of the cylinder, the fixing strap 4 restrains radial swing, and the pulley 52 assembly allows for slight displacement of the cylinder to buffer vibrations while maintaining positioning accuracy, ensuring stable fixing under dynamic loads. The entire process can be completed without tools, achieving a balance between safety and ease of operation.

[0032] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
