Description

Technical Field

[0001] This utility model relates to a fixing frame, and more particularly to a fixing frame for a hydrogen storage cylinder. Background Technology

[0002] The on-board hydrogen system is a crucial component of fuel cell vehicles, providing fuel to the fuel cell engine, much like the "fuel tank" in a traditional gasoline car. The hydrogen storage tank mounting frame is an important part of the on-board hydrogen system, providing fixation and support for components such as the hydrogen storage tank, valves, filling port, pressure reducing valve, and hydrogen pipelines, ensuring that the storage tank and pipelines can provide the fuel cell system with hydrogen at a stable pressure and flow rate.

[0003] In existing technologies, hydrogen storage cylinders are usually fixed horizontally within a fixed frame. This structure has the problem of occupying a lot of space. Moreover, the dynamic movement of the vehicle during driving can lead to poor stability of the hydrogen storage cylinder. With the hydrogen storage cylinder arranged horizontally and the outlet located at one end of the fixed frame, a small amount of hydrogen can leak from the outlet. The leaked hydrogen is easy to accumulate and not easy to dissipate, which can easily lead to false alarms in the system. Utility Model Content

[0004] The purpose of this invention is to provide a fixing frame for hydrogen storage cylinders to solve the technical problems in the prior art.

[0005] This utility model provides a hydrogen storage cylinder fixing frame, including a frame body, at least one longitudinal mounting plate is fixed on the frame body, and multiple gas cylinder straps are fixed on both sides of the longitudinal mounting plate. The hydrogen storage cylinder is fixed on both sides of the longitudinal mounting plate by the gas cylinder straps, and a cylinder valve is provided at the top of the hydrogen storage cylinder.

[0006] In the aforementioned hydrogen storage cylinder fixing frame, preferably, the frame body includes a bottom frame, a top frame, a frame mounting plate and longitudinal connecting rods, two longitudinal connecting rods form a group, the bottom frame and the top frame are fixedly connected by at least one group of longitudinal connecting rods, and a longitudinal mounting plate is fixed between the two longitudinal connecting rods in each group.

[0007] In the aforementioned hydrogen storage cylinder fixing frame, preferably, two frame mounting plates are symmetrically fixed at the bottom of the bottom frame, and mounting holes are provided at both ends of the frame mounting plates.

[0008] In the aforementioned hydrogen storage cylinder fixing frame, preferably, the longitudinal mounting plate has multiple weight-reduction holes.

[0009] In the aforementioned hydrogen storage cylinder fixing frame, preferably, gas cylinder retaining rings are installed at the top and bottom of both sides of the longitudinal mounting plate.

[0010] In the aforementioned hydrogen storage cylinder fixing frame, preferably, a transverse reinforcing rod and an oblique reinforcing rod are provided between adjacent longitudinal connecting rods on the same side.

[0011] Preferably, the aforementioned hydrogen storage cylinder fixing frame also includes an outer skin, the outer skin having a top plate, the bottom of the outer skin being an open structure, and the top plate of the outer skin having a plurality of first vent holes.

[0012] In the aforementioned hydrogen storage cylinder fixing frame, preferably, the upper end of the side wall of the outer skin is provided with a plurality of second vent holes.

[0013] Compared with existing technologies, this utility model includes a frame body with at least one longitudinal mounting plate fixed on it. Multiple gas cylinder straps are fixed to both sides of the longitudinal mounting plate. Hydrogen storage cylinders are fixed to both sides of the longitudinal mounting plate via these straps, and a valve is located at the top of each hydrogen storage cylinder. This utility model vertically fixes the hydrogen storage cylinder to the longitudinal mounting plate, and the valve is located at the top. During use, any small amount of leaked hydrogen can quickly dissipate and does not easily accumulate, thus solving the problem of false alarms. Furthermore, the longitudinal arrangement of the hydrogen storage cylinder occupies less space, improving vehicle space utilization. It also reduces the impact of lateral forces during vehicle movement, which is beneficial for maintaining stability when the vehicle is turning or driving on uneven surfaces, reducing internal stress caused by the vehicle's dynamic movement, and improving safety.

[0014] Due to the limitations of heavy-duty trucks, the existing horizontal arrangement of gas cylinders is not suitable for large-capacity gas cylinders, especially those larger than 400L. The vertical arrangement of gas cylinders does not have this limitation and is also compatible with the arrangement of smaller-capacity gas cylinders. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Embodiments of this utility model: such as Figure 1 and Figure 2 As shown, a hydrogen storage cylinder fixing frame includes a frame body 1, at least one longitudinal mounting plate 2 is fixed on the frame body 1, and multiple gas cylinder straps 3 are fixed on both sides of the longitudinal mounting plate 2. The hydrogen storage cylinder 4 is fixed to both sides of the longitudinal mounting plate 2 by the gas cylinder straps 3, and a cylinder valve is provided at the top of the hydrogen storage cylinder 4.

[0020] This application utilizes a longitudinal mounting plate 2 on the main frame 1 to secure the hydrogen storage cylinder 4 to the mounting plate 2 using cylinder straps 3, thus placing the hydrogen storage cylinder 4 vertically. This effectively reduces the space occupied by the hydrogen storage cylinder 4 in the vehicle chassis, improving space utilization. Furthermore, the cylinder valve of the hydrogen storage cylinder 4 is located at the top, allowing any minor hydrogen leaks to dissipate upwards, preventing hydrogen accumulation and reducing the possibility of false alarms in the hydrogen system. Additionally, the top-positioned valve facilitates the arrangement of pipe fittings and effectively reduces the risk of collisions.

[0021] It should be noted that the number of longitudinal mounting plates 2 can be increased or decreased according to the size of the vehicle model. In this embodiment, two longitudinal mounting plates 2 are preferably provided. Two hydrogen storage cylinders 4 are installed on one longitudinal mounting plate 2, and a total of four hydrogen storage cylinders 4 can be installed on the two longitudinal mounting plates 2.

[0022] Specifically, the frame body 1 includes a bottom frame 5, a top frame 6, a frame mounting plate 7, and longitudinal connecting rods 8. Two longitudinal connecting rods 8 form a group. The bottom frame 5 and the top frame 6 are fixedly connected by at least one group of longitudinal connecting rods 8. A longitudinal mounting plate 2 is fixed between the two longitudinal connecting rods 8 in each group.

[0023] Both the bottom frame 5 and the top frame 6 are rectangular frames, and in this embodiment, the bottom frame 5 and the top frame 6 have the same dimensions. Since two longitudinal mounting plates 2 are preferably provided in this embodiment, the top frame 6 is fixedly connected to the bottom frame 5 by two sets of longitudinal connecting rods 8.

[0024] To reduce the overall weight of the hydrogen storage cylinder fixing frame, it is preferable to have multiple weight-reducing holes 10 on the longitudinal mounting plate 2. The weight-reducing holes 10 are preferably circular holes.

[0025] Two frame mounting plates 7 are symmetrically fixed to the bottom of the base frame 5, and each of the frame mounting plates 7 has mounting holes 9 at both ends. The frame mounting plates 7 are used to fix and connect to the vehicle chassis by bolt assembly.

[0026] To improve structural strength, a transverse reinforcing bar 12 and a diagonal reinforcing bar 13 are provided between adjacent longitudinal connecting bars 8 on the same side.

[0027] Gas cylinder retaining rings 11 are installed at the top and bottom of both sides of the longitudinal mounting plate 2. The gas cylinder retaining rings 11 are used to limit the upper and lower ends of the gas cylinder.

[0028] Furthermore, this application also includes an outer skin 14, which has a top plate and an open bottom structure. The top plate of the outer skin 14 has a plurality of first vent holes 15. The upper end of the sidewall of the outer skin 14 has a plurality of second vent holes 16.

[0029] The outer skin 14 serves to protect the hydrogen storage cylinder 4. It surrounds the main frame 1 and can prevent flying stones and other objects from hitting the vehicle during driving. It can also provide a certain degree of protection for the hydrogen storage cylinder 4 and its valves in the hydrogen system.

[0030] The method of using this utility model is as follows: Two frame mounting plates 7 on the main frame 1 are fixed to the vehicle chassis using bolt assemblies. Then, the hydrogen storage cylinder 4 is fixed to the longitudinal mounting plate 2 using straps 3. Next, a cylinder retaining ring 11 is installed at the upper and lower ends of the hydrogen storage cylinder 4, and the cylinder retaining ring 11 is fixedly connected to the longitudinal mounting plate 2. The cylinder retaining ring 11 serves to assist in stabilizing the hydrogen storage cylinder 4. Then, the fittings are connected to the cylinder valve. Finally, the outer skin 14 is installed from the top of the main frame 1. After the outer skin 14 is installed in place, the bottom of the outer skin is fixed to the bottom frame 5 using bolt assemblies.

[0031] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings.
