[0027] The following describes in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, the orientation terms such as "top, bottom" generally refer to the top and bottom of the corresponding components in the gravity direction in the use state, and "inner, outer" refer to the inside and outside relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another and do not have an order or importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0029] As Figure 1-8As shown in the figure, the present disclosure provides an installation structure for an on-vehicle gas cylinder, including: a plurality of support members 1 spaced along the axial direction of the gas cylinder 8, and the side of the support member 1 for contacting the gas cylinder 8 is configured as an arc-shaped structure 11 that fits the outer surface of the gas cylinder 8; a first reinforcing member 5, the support member 1 is provided with a hollow, and a plurality of first reinforcing members 5 are spaced and arranged in the hollow area for supporting the arc-shaped structure 11; a second reinforcing member 3, arranged between two adjacent support members 1 and a plurality of second reinforcing members 3 are spaced; and a strap 2, each support member 1 is connected with a strap 2, and the strap 2 and the arc-shaped structure 11 enclose a ring that fits the outer surface of the gas cylinder 8 to fix the gas cylinder 8.

[0030] Through the above technical solution, in the installation structure of the on-vehicle gas cylinder 8 provided by the present disclosure, a plurality of support members 1 are arranged along the axial direction of the gas cylinder 8 to support the gas cylinder 8, which can improve the stability of the gas cylinder 8. The side of the support member 1 in contact with the gas cylinder 8 is configured as an arc-shaped structure 11 to prevent the gas cylinder 8 from shifting. The arc-shaped structure 11 and the strap 2 form a ring to fix the gas cylinder 8, and each support member 1 is connected with a strap 2 to make the fixation of the gas cylinder 8 more firm. The support member 1 is provided with a hollow to reduce the weight, and the first reinforcing member 5 is arranged in the hollow area to improve the radial support strength of the support member 1. The support members 1 are connected by the second reinforcing member 3 to improve the axial strength of the installation structure. Both the first reinforcing member 5 and the second reinforcing member 3 are provided with a plurality of and spaced, so as to improve the strength of the installation structure while reducing the weight.

[0031] As an optional implementation manner, as Figure 1-2 and Figure 5-6 shown, the support member 1 can be configured in any suitable shape. Exemplarily, in the present disclosure, the support member 1 includes two support beams 14 arranged oppositely, a connecting beam 15 connected to one end of the two support beams 14, and an arc-shaped structure 11 connected to the other end of the two support beams 14. The connecting beam 14 is installed on the vehicle frame. Compared with the mounting seat in the related art, the connecting beam 14 is thinner, so that the center of gravity of the gas cylinder 8 can be lower, and the driving stability of the gas cylinder 8 and the whole vehicle can be improved. One end of the first reinforcing member 5 is connected to the arc-shaped structure 11, and the other end is connected to the connecting beam 15 or the support beam 14 for supporting the arc-shaped structure 11. The support member 1 is perpendicular to the axis of the gas cylinder 8. The extension lines of a plurality of first reinforcing members 5 intersect at a point and this point is located on the axis of the gas cylinder 8. In this way, the load direction transmitted by the gas cylinder 8 is always consistent with the extension direction of the first reinforcing member 5, and the load-bearing capacity of the first reinforcing member 5 can be fully utilized.

[0032] Optionally, the thicknesses of a plurality of first reinforcing members 5 are different. For example, the thickness of the first reinforcing member 5 located at the center of the arc-shaped structure 11 is greater than that of the other first reinforcing members 5, and can be twice the thickness of the other first reinforcing members 5, for improving the vertical load resistance ability.

[0033] As an alternative embodiment, the support member 1, the first reinforcing member 5, and the second reinforcing member 3 are all configured as aluminum alloy members. Compared with the steel installation structure in the related art, using aluminum alloy material can make the installation structure lighter. For example, it can be 6061 aluminum alloy, which has relatively high strength, good plasticity, and excellent corrosion resistance.

[0034] As an alternative embodiment, as Figure 1-2 and Figure 4-6 shown, the connecting beam 15 is provided with a horizontal mounting hole 12, and the connecting beam 15 may optionally be provided with a mounting plate 4 extending beyond the support member 1 in a direction away from the arc structure 11. Generally, since the connecting beam 15 needs to contact the vehicle frame, the mounting plate 4 is disposed on the two outermost support members 1. The mounting plate 4 is provided with a vertical mounting hole 41. There are two ways for the installation structure to be located on the vehicle frame. The horizontal plane of the installation structure provides the horizontal mounting hole 12, which is bolted to the horizontal base, and in this case, the mounting plate 4 does not need to be provided; the side surface of the installation structure provides the vertical mounting hole 41, which is bolted to the side surface of the vehicle frame. If the side connection with the vehicle frame is selected, the horizontal mounting hole 12 is reserved as a common interface for installing other components.

[0035] As an alternative embodiment, as Figure 1-2 、 Figure 4 and Figure 7 shown, the installation structure further includes a rotating shaft 6 and a fastener 7. The rotating shaft 6 is rotatably connected to the end of the strap 2 and is perpendicular to the extending direction of the strap 2. The fastener 7 passes through the rotating shaft 6 and is connected to the support member 1, that is, the fastener 7 can rotate with the rotating shaft 6, so that the angle of the fastener 7 can be adjusted to be applicable to various support members 1. For example, the fastener 7 is a connecting bolt, and the strap 2 is made of stainless steel. The thickness of the strap 2 is selected according to the weight of the gas cylinder 8 and the load condition, for example, the strap 2 with a thickness of 2 mm to 3 mm is used.

[0036] Optionally, the end of the strap 2 is bent outward and connected to the strap 2 to form a connection ring 21 for connecting the rotating shaft 6. The rotating shaft 6 is inserted into the connection ring 21 and can rotate along the connection ring 21. The center of the connection ring 21 is provided with an avoidance hole 211 for the fastener 7 to pass through. For example, slots can be provided at both ends of the rotating shaft 6 to limit the connection ring 21. The connection ring 21 is sleeved on the rotating shaft 6, so that both sides of the fastener 7 are stressed, and the stress is more uniform, and the strap 2 will not easily break away from the fastener 7. A connecting plate 13 is connected between the support beam 14 and the arc structure 11. The fastener 7 is connected to the connecting plate 13 and is perpendicular to the connecting plate 13. To enhance the load-bearing capacity of the connecting plate 13, the thickness of the connecting plate 13 is specifically increased.

[0037] As an alternative embodiment, the multiple support members 1, the first reinforcing member 5, and the second reinforcing member 3 are integrally provided. The integral device is symmetrically arranged, which allows the installation direction to be interchanged and has good anti-misassembly performance. The integral arrangement can use the integral die-casting forming process, resulting in a higher overall structural performance. Moreover, no connecting members need to be provided, making the structure lighter. At the same time, the installation steps can be reduced, and the assembly is simple. Of course, in other embodiments, the support member 1 and the first reinforcing member 5 can also be integrally provided, and the second reinforcing member 3 is welded to the support member 1.

[0038] As an alternative embodiment, the mounting structure further includes a shock pad. The shock pad is provided on the side where the arc-shaped structure 11 and the strap 2 are in contact with the gas cylinder 8. The shock pad can prevent the gas cylinder 8 from being damaged and at the same time increase the friction between the gas cylinder 8 and the mounting structure, making the installation more secure. For example, the shock pad is a rubber pad, which is bonded to the arc-shaped structure 11 and the strap 2 and has a width greater than that of the arc-shaped structure 11 and the strap 2.

[0039] The present disclosure also provides a vehicle, including: a vehicle frame; and the above-described mounting structure for the on-vehicle gas cylinder. The mounting structure is provided on the vehicle frame, and the axial extension direction of the gas cylinder 8 is perpendicular to the traveling direction of the vehicle. The mounting structure for the on-vehicle gas cylinder is applicable to commercial vehicles such as heavy trucks, medium trucks, light trucks, micro trucks, and buses. Further, it is also applicable to the installation of high-pressure gas cylinders and cryogenic gas cylinders in passenger vehicles. By adopting the mounting structure for the on-vehicle gas cylinder provided by the present disclosure, while achieving lightweight, the strength of the installation of the gas cylinder 8 is ensured.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0041] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0042] Furthermore, any combination can be made among the various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
