In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0032] Such as Figures 1 to 4As shown in the figure, the present utility model provides an air storage cylinder mounting device for mounting a plurality of air storage cylinders 2 to a vehicle body 1. The air storage cylinder mounting device includes at least two mounting brackets 10 and multiple groups of support members 20. The at least two mounting brackets 10 are spaced apart along a first direction. Multiple groups of mounting holes 111 are provided on the mounting brackets 10, and the multiple groups of mounting holes 111 are spaced apart along the length direction of the mounting brackets 10. The mounting brackets 10 can select any one of the multiple groups of mounting holes 111 to be mounted to the vehicle body 1, so as to adapt to different mounting positions on the vehicle body 1. Some of the multiple groups of support members 20 are arranged on the side of the mounting brackets 10 facing away from the vehicle body 1 and are spaced apart along the length direction of the mounting brackets 10, and the remaining groups are arranged on the side of the mounting brackets 10 facing the vehicle body 1 and are spaced apart from the vehicle body 1. The number of support members 20 included in each group is equal to the number of mounting brackets 10 and is connected in one-to-one correspondence. The multiple groups of support members 20 are used to support the multiple air storage cylinders 2 in one-to-one correspondence. The air storage cylinder mounting device provided by the present utility model can mount multiple air storage cylinders 2 simultaneously, making the multiple air storage cylinders 2 mounted compactly, saving a lot of mounting space, and being beneficial to the flexible arrangement of other system components of the whole vehicle; and the structure of the air storage cylinder mounting device is simple and has high versatility.

[0033] As Figure 1 shown, in this embodiment, the number of mounting brackets 10 is two. Of course, it can also be more than two, and it is not limited to this embodiment. In this embodiment, three groups of support members 20 are provided. Two of the three groups of support members 20 are arranged on the side of the mounting brackets 10 facing away from the vehicle body 1, and one group is arranged on the side of the mounting brackets 10 facing the vehicle body 1. Of course, the number of groups of support members 20 can also be more than three or less than three, and it is specifically determined according to the number of air storage cylinders 2 to be mounted, and it is not limited to this embodiment.

[0034] Furthermore, the mounting bracket 10 includes two sides 12 spaced apart along the first direction. Two support members 20 in each group are selectively connected to one of the two sides 12 of the corresponding mounting bracket 10. Optionally, the two support members 20 in a group can be respectively connected to the inner sides 12 of the corresponding mounting bracket 10. At this time, the distance between the two support members 20 is d1; or, one of the two support members 20 in a group can be connected to the inner side 12 of the corresponding mounting bracket 10, and the other can be mounted on the outer side 12 of the corresponding mounting bracket 10. At this time, the distance between the two support members 20 is d2; or, the two support members 20 in a group can also be respectively connected to the outer sides 12 of the corresponding mounting bracket 10. At this time, the distance between the two support members 20 is d3. Then d1 < d2 < d3, that is, by connecting the support members 20 to different sides 12 of the mounting bracket 10, the distance between the two support members 20 in a group can be adjusted, so as to adapt to air storage cylinders 2 of different specifications, and reference can be made to Figure 2 and Figure 3The installation position of the upper set of support members 20 on the mounting frame 10 and the size of the gas cylinder 2 supported by it.

[0035] In addition, continue to refer to Figure 2 and Figure 3 Of the two groups of support members 20 located on the side facing away from the vehicle body 1, one group of support members 20 is at least partially overlapped with the vehicle body 1, while the other group of support members 20 located away from the vehicle body 1 is offset from the vehicle body 1. The group of support members 20 located on the side of the mounting frame 10 facing away from the vehicle body 1 and offset from the vehicle body 1 can be arranged at the same height as the group of support members 20 located on the side of the mounting frame 10 facing the vehicle body 1. Alternatively, the group of support members 20 located on the side of the mounting frame 10 facing away from the vehicle body 1 can be mounted on the outer side 12 of the corresponding mounting frame 10, while the group of support members 20 located on the side of the mounting frame 10 facing the vehicle body 1 can be mounted on the inner side 12 of the corresponding mounting frame 10; alternatively, the group of support members 20 located on the side of the mounting frame 10 facing away from the vehicle body 1 can be mounted on the inner side 12 of the corresponding mounting frame 10, while the group of support members 20 located on the side of the mounting frame 10 facing the vehicle body 1 can be mounted on the outer side 12 of the corresponding mounting frame 10. The two groups of support members 20 are distributed at the same height and do not interfere with each other, which further improves the compactness of the installation of the gas cylinder 2.

[0036] like Figure 1 As shown, in this embodiment, the mounting bracket 10 has a U-shaped cross-section, including a bottom surface 11 and two opposing side surfaces 12. Multiple sets of mounting holes 111 are provided on the bottom surface 11, and the support member 20 is selectively connected to one of the two side surfaces 12. Alternatively, the mounting bracket 10 may have a π-shaped cross-section, and this is not limited to this embodiment. Any structure including two opposing side surfaces 12 is acceptable.

[0037] Reference Figure 1 and Figure 4 In this embodiment, the support member 20 includes a connecting portion 21 and a supporting portion 22. The connecting portion 21 is used to connect to the mounting bracket 10, and the supporting portion 22 is used to support the gas reservoir 2. The connecting portion 21 and the supporting portion 22 are connected in an L-shape, resulting in a simple and reasonable structure. Optionally, the side 12 of the mounting bracket 10 is provided with a first connecting hole 121, and the connecting portion 21 is provided with a second connecting hole 211. The connecting member connects the mounting bracket 10 and the connecting portion 21 through the first connecting hole 121 and the second connecting hole 211. This connection method is simple, reliable, and easy to assemble and disassemble.

[0038] Furthermore, the support portion 22 is arc-shaped to better fit the outer surface of the gas cylinder 2, thereby stably supporting the gas cylinder 2. Furthermore, the support surface of the support portion 22 is provided with a flexible cushion layer to flexibly support the gas cylinder 2 and better protect the gas cylinder 2.

[0039] like Figure 2 and Figure 3As shown, the air storage cylinder mounting device provided by the present utility model further includes a hoop 30, which is used to tightly fasten the support portion 22 and the air storage cylinder 2. After the air storage cylinder 2 is supported on the support member 20, the hoop 30 is sleeved on the support portion 22 and the air storage cylinder 2 and tightened to lock and fix the air storage cylinder 2, avoiding displacement of the air storage cylinder 2 and improving the stability of the air storage cylinder 2.

[0040] Furthermore, as Figure 1 shown, a limiting portion 23 extending in the same direction as the connecting portion 21 is provided at one end of the support portion 22 away from the connecting portion 21. The limiting portion 23, the connecting portion 21, and the support portion 22 form a limiting space, which is used to limit the hoop 30 to prevent the hoop 30 from slipping off the support portion 22.

[0041] The present utility model also provides a pneumatic braking vehicle, which includes a vehicle body 1, a plurality of air storage cylinders 2, and the above-mentioned air storage cylinder mounting device. The vehicle body 1 has structures such as cross beams and longitudinal beams.
