Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen supply, in particular to a gas cylinder fixing component and a device thereof. Background Art

[0002] With the rapid development of new energy heavy-duty trucks in the truck industry, lightweight vehicle bodies are receiving increasing attention. Cylinder frames increasingly use aluminum alloy or magnesium alloy profiles. This material replacement also results in a certain increase in the size of each component, which limits the space available for installing the cylinders. Existing methods for bundling cylinders involve first placing the cylinder to be fixed on a base, then installing it with straps, tightening the straps from both ends and securing them to the base with bolts, or securing the straps from both ends of the base and tightening and securing them from the middle with bolts. In cylinder frames primarily made of aluminum alloy or magnesium alloy profiles, when multiple cylinders need to be placed side by side, installing the bolts on the inside of adjacent cylinders is difficult due to limited space. When multiple cylinders need to be placed side by side, installing the bolts in the middle of the straps is also difficult due to limited space, requiring significant time and effort, resulting in low production efficiency. Utility Model Content

[0019] The present invention will be described in further detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0020] Example 1

[0021] See Figure 1~Figure 2The embodiment of the present invention provides a gas cylinder fixing assembly, specifically comprising a base 1 and a steel strap 2. The upper end of the base 1 is provided with a mounting surface and a fixing surface 1-1; the mounting surface is an arc-shaped surface adapted to the contour of the gas cylinder; a first connecting member 3 is fixed to the fixing surface 1-1 at one end of the base 1 by bolts, and the first connecting member 3 has an assembly hole 3-1; a second connecting member 4 is riveted to one end of the steel strap 2, and the lower end of the second connecting member 4 extends into the assembly hole 3-1 so that the second connecting member 4 is engaged with the first connecting member 3; the other end of the steel strap 2 is fixed to the fixing surface 1-1 at the other end of the base 1 by bolts. The gas cylinder to be fixed is placed on the mounting surface, and then the second connecting member 4 riveted to one end of the steel strap 2 is directly extended into the assembly hole 3-1 of the first connecting member 3 so that one end of the steel strap 2 is engaged with the first connecting member 3. The other end of the steel strap is fastened to the gas cylinder and fixed to the fixing surface 1-1 at the other end of the base 1 by bolts 5. In this way, the traditional method of fixing and tightening the two ends of the steel strap or fixing both ends and then tightening it in the middle is changed to connecting from only one end and quickly snapping on the other end, making the installation of the gas cylinder more convenient and quick, and avoiding the problem of difficulty in fixing one end on the inside of the gas cylinder when the gas cylinders are placed side by side, greatly reducing the difficulty of installation and improving installation efficiency.

[0022] Furthermore, the first connecting member 3 is L-shaped, the horizontal part of the L-shape is fixed to the fixing surface 1-1 at one end of the base 1, and the vertical part thereof is provided with the assembly hole 3-1; the lower end of the second connecting member 4 is bent upward, and the bent part passes through the assembly hole 3-1 so that the second connecting member 4 is clamped with the first connecting member 3, so that the inside of the gas cylinder can be quickly fixed.

[0023] Furthermore, the other end of the steel strap 2 is bent outward to be parallel to the fixing surface 1-1 at the other end of the base 1 and then fixed to the fixing surface 1-1 by a fastener, and a pair of triangular reinforcement ribs 6 are provided at the bending point to increase the structural strength of the fastening point.

[0024] Furthermore, rubber pads 7 are bonded to the inner side of the mounting surface and the inner side of the steel strap 2. The rubber pads 7 are provided to prevent the gas cylinder from being scratched. At the same time, the rubber pads 7 can be further compressed during the gas cylinder fixing process to make the gas cylinder more firmly fixed in the mounting surface, thereby preventing the gas cylinder from loosening and causing deformation of the pipeline connected to the gas cylinder, causing a dangerous accident of hydrogen leakage, and at the same time preventing the loose gas cylinder from causing impact on the overall fixing assembly, resulting in reduced vehicle durability.

[0025] In addition, in order to make the rubber pad 7 as compressible as possible and enable gas cylinders with similar specifications to use the same fixing assembly, a gap is set between the other end of the steel strap 2 and the fixing surface 1-1 of the base 1, and the gap value is not less than 10 mm.

[0026] Furthermore, the thickness of the first connecting member 3 and the second connecting member 4 are 2 to 5 times the thickness of the steel strap 2, thereby increasing the reliability and safety of the connection and avoiding breakage caused by excessive force.

[0027] Furthermore, the base 1 is made of aluminum alloy or magnesium alloy and is produced by an extrusion molding process, providing a mounting surface for placing the steel strap 2.

[0028] Example 2

[0029] An embodiment of the present utility model discloses a gas cylinder fixing device, which includes the gas cylinder fixing assembly described in Example 1, and the gas cylinder fixing assemblies are arranged in several rows. Due to the size limitation of the vehicle actually used, they are generally arranged in two rows and three layers. Two fixing assemblies need to be set on each row, and each gas cylinder needs two fixing assemblies for fixation, that is, in actual use, the gas cylinders are arranged in two rows and three layers, and each layer is provided with four gas cylinder fixing assemblies. At this time, the first connecting member 3 and the second connecting member 4 in the four gas cylinder fixing assemblies on the same layer are both located on the inner side of the gas cylinder fixing assembly. When the gas cylinder is installed, the gas cylinder is first placed in the installation surface, and then the second connecting member 4 riveted at one end of the steel strap 2 is clamped with the first connecting member 3 located on the inner side, and then the other end of the steel strap 2 located on the outer side is tightened and fixed by bolts, so that fixation can be quickly achieved when the inner installation space is limited.

[0030] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
