[0002] In related art, LNG cylinders are mounted on the vehicle frame behind the cab via LNG cylinder brackets. These brackets are connected by welding, a complex process that requires improved production efficiency. Furthermore, the LNG cylinder brackets require multiple external reinforcement plates for welding, resulting in numerous welds and poor welding process consistency. The external reinforcement plates also have poor load-bearing capacity, which can easily cause weld cracking and deformation when the vehicle is traveling in poor road conditions, compromising the reliability of the cylinder installation.

[0035] The following describes an LNG cylinder bracket 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] like Figure 1-Figure 3As shown, the LNG cylinder support 1 according to an embodiment of the present invention includes: a support frame 100 and a reinforcing rib 200. The support frame 100 includes a first support plate 110 and a second support plate 120. The first support plate 110 and the second support plate 120 are both vertically arranged and spaced apart from each other. The tops of the first support plate 110 and the second support plate 120 are each configured with a gas cylinder upper mounting portion 11. The support frame 100 has a receiving hole 101 below the upper mounting portion that passes through the first and second support plates 110 and 120. The first and second support plates 110 and 120 have a gas cylinder lower mounting portion 12 at the bottom of the receiving hole 101. The reinforcing rib 200 is located on both sides of the support frame 100 and is mounted to the first and second support plates 110 and 120 by fasteners. The edges of the reinforcing rib 200 are configured with reinforcing flanges 210 that fold inwardly of the support frame 100.

[0037] For example, the LNG cylinder bracket 1 is specifically a double LNG cylinder bracket, which is used to install LNG cylinders on gas tractors. The upper cylinder mounting portion 11 and the lower cylinder mounting portion 12 are respectively mounted with LNG cylinders. The first support plate 110 and the second support plate 120 are arranged parallel to each other. In addition to being connected by the reinforcing ribs 200, the first support plate 110 and the second support plate 120 can also be provided with a connecting beam 130, a connecting plate and other structures to form a support frame 100. The support frame 100 is constructed as a rectangular parallelepiped structure, in which one cylinder 2 is placed on top of the upper cylinder mounting portion 11 and fixed, and the other cylinder 2 is placed on top of the lower cylinder mounting portion 12 and fixed. The upper cylinder mounting portion 11 mounts the cylinder 2 on top of the LNG cylinder bracket 1, and the cylinder 2 mounted on the lower cylinder mounting portion 12 passes through the receiving hole 101 and is partially accommodated inside the support frame 100.

[0038] According to the LNG cylinder bracket 1 of the embodiment of the present invention, the reinforcement rib 200 is provided to play a structural reinforcement role between the first support plate 110 and the second support plate 120. The reinforcement rib 200 is installed with the first support plate 110 and the second support plate 120 by fasteners. The first support plate 110 and the second support plate 120 and the reinforcement rib 200 only need to align the holes of the fasteners to ensure accurate assembly. Compared with the welding process, the assembly accuracy is improved. For example, during mass production, the fastener installation hole positions of each reinforcement rib 200 and the first support plate 110 and the second support plate 120 are determined in advance, and the product consistency is better. The use of fasteners to install the reinforcement rib 200 and the first support plate 110 and the second support plate 120 is easy to operate, simple to assemble, and reduces the number of processing steps. There is no need to set up an additional reinforcement connecting plate structure for welding, which avoids insufficient strength of the reinforcement connecting plate, eliminates welding defects, and reduces the risk of insufficient force strength of the LNG cylinder bracket 1. Furthermore, the reinforcing ribs 200 are constructed with reinforcing flanges 210 that fold inwardly toward the support frame 100, forming a three-dimensional reinforcement structure with enhanced load-bearing capacity. Furthermore, the reinforcing flanges 210 do not occupy space outside the support frame 100. The use of fasteners also makes the reinforcing ribs 200 removable. For example, when inspecting the gas cylinders 2, the reinforcing ribs 200 can be removed for easy access.

[0039] Therefore, the LNG cylinder bracket 1 according to the embodiment of the present invention has the advantages of strong bearing capacity, high product consistency, and reduced processing steps.

[0040] In some specific embodiments of the present invention, Figure 3 As shown, both sides of the first support plate 110 and both sides of the second support plate 120 are constructed with mounting flanges 111 folded in directions opposite to each other, and the reinforcing ribs 200 are installed on the mounting flanges 111 by fasteners.

[0041] The installation hem 111 is constructed by the first support plate 110 and the second support plate 120. On the one hand, it provides space for fasteners to fix the reinforcing rib 200, so as to fix the reinforcing rib 200 and the installation hem 111. On the other hand, it also strengthens the structure of the first support plate 110 and the second support plate 120. The hem structure formed on both sides of the first support plate 110 and the second support plate 120 improves the load-bearing capacity of the first support plate 110 and the second support plate 120.

[0042] Furthermore, if Figure 2As shown, the LNG cylinder support 1 further includes a connecting beam 130. The ends of the connecting beam 130 are mounted to the mounting flanges 111 of the first support plate 110 and the mounting flanges 111 of the second support plate 120, respectively, via fasteners. The connecting beam 130 connects the first and second support plates 110, 120 at their endpoints, thereby connecting the first and second support plates 110, 120 to form a rectangular support frame 100. The support frame 100 is reinforced by the reinforcing ribs 200 and the connecting beam 130, ensuring stability and securement for mounting the gas cylinder 2.

[0043] For example, the cross-section of the connecting beam 130 is constructed into an "L" shape, and there are fasteners for fixing the reinforcing ribs 200 and fasteners for fixing the connecting beam 130 on the installation fold 111 respectively. The fasteners for fixing the reinforcing ribs 200 and the fasteners for fixing the connecting beam 130 on the installation fold 111 of the first support plate 110 are all on the same straight line, and the fasteners for fixing the reinforcing ribs 200 and the fasteners for fixing the connecting beam 130 on the installation fold 111 of the second support plate 120 are all on the same straight line. The arrangement of the fasteners is relatively neat, and the force is more evenly distributed.

[0044] In some specific embodiments of the present invention, Figure 3 As shown, the reinforcing rib 200 is constructed in an "X" shape and has a first upper connecting arm 21 and a first lower connecting arm 22, a second upper connecting arm 23 and a second lower connecting arm 24. The first upper connecting arm 21 and the first lower connecting arm 22 are installed on the first support plate 110 through fasteners, and the second upper connecting arm 23 and the second lower connecting arm 24 are installed on the second support plate 120 through fasteners.

[0045] For example, the "X"-shaped reinforcing rib 200 is integrally formed. Specifically, the reinforcing rib 200 is a stamped part, which is formed by stamping and forming a reinforcing flange 210 structure, and has a high structural strength. The first upper connecting arm 21 and the second lower connecting arm 24 extend in the same direction, and the second upper connecting arm 23 and the first lower connecting arm 22 extend in the same direction. The angle between the first upper connecting arm 21 and the second upper connecting arm 23 is greater than 90°, and the angle between the first lower connecting arm 22 and the second lower connecting arm 24 is greater than 90°. Furthermore, the angle between the first upper connecting arm 21 and the first lower connecting arm 22 is less than 90°, and the angle between the second upper connecting arm 23 and the second lower connecting arm 24 is less than 90°. In this way, the reinforcing rib 200 can span a wider width and cover a larger area on the side of the support frame 100, thereby playing a good reinforcing role. In addition, the first upper connecting arm 21, the first lower connecting arm 22, the second upper connecting arm 23 and the second lower connecting arm 24 are respectively fixed by two fasteners. The two fasteners on each connecting arm are spaced apart in the vertical direction, and the bearing capacity is stronger.

[0046] Furthermore, if Figure 3As shown, transition chamfers 25 are formed at the connections of the first upper connecting arm 21, the first lower connecting arm 22, the second upper connecting arm 23, and the second lower connecting arm 24. The transition chamfers 25 form arc transitions at the connections of different connecting arms. Similarly, the reinforcing flanges 210 also form arc transitions at the connections of different connecting arms, preventing the reinforcing ribs 200 from being damaged by stress and further improving the structural strength.

[0047] In some specific embodiments of the present invention, Figure 2 As shown, there are multiple reinforcing ribs 200, which are arranged in a vertical direction. The multiple reinforcing ribs 200 arranged in the vertical direction can, on the one hand, cover a large area of ​​the side of the support frame 100 to protect the gas cylinder 2 from external impact, and on the other hand, better strengthen the support frame 100.

[0048] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the gas cylinder upper mounting portion 11 and the gas cylinder lower mounting portion 12 both include a support plate 140 , and the support plate 140 is configured as an arc-shaped plate adapted to the outer contour of the gas cylinder 2 .

[0049] For example, the support plate 140 of the upper mounting part is installed on the top surface of the support frame 100, and the support plate 140 of the lower mounting part is connected to the bottom of the mounting accommodating hole 101. The support plate 140 forms an arc to adapt to the outer contour of the gas cylinder 2, so that the gas cylinder 2 can be stably installed on the support plate 140, and the support plate 140 plays a good supporting role for the gas cylinder 2.

[0050] Furthermore, if Figure 2 As shown, the support plate 140 extends outward from the support frame 100 and extends beyond the outer side surfaces of the first and second support plates 110, 120. By extending beyond the outer side surfaces of the first and second support plates 110, 120, the support plate 140 has a larger support area. Furthermore, a band 3 can be provided at the position where the support plate 140 extends beyond the first and second support plates 110, 120 for further securing. The band 3 can be wrapped from the bottom of the support plate 140 around the outer periphery of the support plate 140 and the gas cylinder 2, tightening and securing the gas cylinder 2.

[0051] Furthermore, if Figure 2 As shown, both ends of the support plate 140 are configured with cuff connection blocks 150 suitable for fixing the cuff 3 , and the cuff connection blocks 150 are connected to the outer side of the first support plate 110 or the second support plate 120 .

[0052] For example, the width between the cuff connection blocks 150 at both ends of the support plate 140 is equal to the diameter of the gas cylinder 2. The two ends of the cuff 3 are respectively fixed to the cuff connection blocks 150 at both ends. The middle portion of the cuff 3 surrounds the gas cylinder 2 and tightens the gas cylinder 2 to the support plate 140. By configuring the cuff connection blocks 150 at both ends of the support plate 140, a fixed position is provided for the cuff 3. In addition, the cuff connection blocks 150 are connected to the first support plate 110 or the second support plate 120, which plays a certain reinforcement role and improves the connection strength of the cuff connection blocks 150.
