Technical Field

[0001] The utility model relates to the technical field of gas storage tanks, in particular to a gas storage tank and a vehicle. Background Art

[0002] Most current automotive air suspension systems use a single-chamber air tank, which is simple and low-cost. The single-chamber air tank mainly stores compressed air for adjusting the height of the suspension to provide a smooth driving experience and good vehicle handling.

[0003] However, this design has a potential limitation; when other systems of the car, such as the braking system, pneumatic tools or air conditioning system, need to use gas, if the gas is taken from the same single-chamber structure, it may interfere with the normal operation of the air suspension system and cause unstable suspension performance; therefore, automakers usually install additional gas tanks to specifically store gas for use by other systems, but this undoubtedly increases the cost of the entire vehicle.

[0030] The automobile air suspension system consists of multiple components, including air springs, shock absorbers, guide mechanisms, thrust rods, buffer limit blocks, etc. Among them, the air spring is the most important part of the air suspension system; and the air tank is mainly used to store and adjust the compressed air required for the air spring.

[0031] See also Figure 1-3 The utility model provides a gas storage tank, including a cylinder body 1 and heads 2 at both ends thereof; the cylinder body 1 includes at least two axially connected sub-cylinder bodies 11; a chamber partition 3 for sealing and separating the inner cavity of the cylinder body 1 is arranged between two adjacent sub-cylinder bodies 11, and the chamber partition 3 is welded to the outer surface of at least one of the two sub-cylinder bodies 11.

[0032] It should be noted that the gas tank in this case is a multi-chamber structure, which is designed mainly to solve the problems that a single-chamber gas tank may encounter in an automobile air suspension system; Figure 1 As shown, in a single-chamber air tank, all compressed air is stored in one chamber; when other systems of the car (such as the braking system, automatic door opening and closing system, etc.) need to use compressed air, air will be taken from this air tank. If air is taken from the single-chamber structure frequently, it may cause insufficient air pressure in the air suspension system, thereby affecting the performance and stability of the car's air suspension system.

[0033] In order to solve this problem, when the air storage tank of the present case has two sub-chambers 111, air is supplied through a double-chamber air storage tank, which has two independent sub-chambers 111, each of which can store compressed air; one of the sub-chambers 111 is specifically used to provide air pressure for the air suspension system, while the other sub-chamber 111 is used to meet the air pressure requirements of other systems; in this way, even if other systems frequently use compressed air, it will not affect the normal operation of the air suspension system; the multi-chamber air storage tank has the following functions: first, since the two sub-chambers 111 do not interfere with each other, it can ensure that the air suspension system always has sufficient air pressure supply, thereby maintaining First, the stability and reliability of the air suspension system; second, the multi-chamber design enables the air tank to meet the air pressure requirements of multiple systems at the same time, improving the flexibility and efficiency of the entire system; third, in some cases, the demand for compressed air from other systems may conflict with the air suspension system. The multi-chamber air tank can avoid such interference and ensure that each system can work normally; in summary, the multi-chamber air tank in this case not only solves the problems that may be encountered with the single-chamber structure, but also improves the stability and reliability of the entire system. Through the use of this air tank, the vehicle can better adapt to various road conditions and driving conditions, and provide a better driving experience and performance.

[0034] At the same time, if Figure 2 As shown, there are also vehicles equipped with two independent gas tanks at the same time, one of which is used to provide air pressure specifically for the air suspension system, and the other is used to meet the air pressure requirements of other systems; but compared with two independent gas tanks, the double-chamber gas tank in this case has the advantages of more efficient space utilization and cost-effectiveness; specifically, the gas tank in this case integrates two chambers into one, which can save space and is particularly suitable for those occasions with limited placement space, while two independent gas tanks require more space for installation and connection; although the gas tank in this case may be It is more complicated to manufacture than a single gas tank, but compared with the installation and maintenance of two completely independent gas tanks, the gas tank in this case is cheaper because the double-chamber gas tank can share some structural elements and connectors, reducing the need for additional pipes and accessories; the gas tank can precipitate impurities and moisture in the air and improve the quality of compressed air. The double-chamber gas tank also has this function, and due to the integrated design, it is easier to control the quality and temperature of the gas; in summary, the gas tank in this case has certain advantages in space utilization, cost-effectiveness and gas quality.

[0035] like Figure 3As shown, the gas storage tank of this case includes a plurality of axially connected sub-barrels 11, and the adjacent sub-barrels 11 are sealed and separated by chamber partitions 3, which can provide greater structural flexibility, and the size and number of each chamber can be easily adjusted as needed to meet the needs of specific applications; the gas storage tank of this case can be customized according to different pressure and capacity requirements, and each sub-chamber 111 can be independently designed to meet specific working pressures or storage capacities, so as to adapt to a variety of applications. In this case, different materials and thicknesses can be selected to construct the sub-barrels 11 according to the pressure requirements of different chambers, which helps to optimize material use and reduce costs, while ensuring that each chamber can withstand its corresponding working pressure.

[0036] like Figure 3 As shown, the chamber partition 3 is welded to the outer surface of at least one of the two sub-barrel bodies 11. For example, one of the sub-barrel bodies 11 of the gas storage tank is an integral structure, and the other sub-barrel body 11 is welded to the sub-barrel body 11 of the integral structure, and the chamber partition 3 is a head 2 at one end of the sub-barrel body 11 of the integral structure, then the chamber partition 3 only needs to be welded to the other sub-barrel body 11 which is not an integral structure; for another example, the gas storage tank includes two sub-barrel bodies 11, both of which have a head 2 at one end and an open end, and the chamber partition 3 is arranged between the two sub-barrel bodies 11, then the chamber partition 3 needs to be welded to the two sub-barrel bodies 11 at the same time. The chamber partition 3 is welded to the outer surface of at least one of the two sub-barrels 11. By welding the chamber partition 3 to the outer surface of the sub-barrel 11, the outer surface welding helps to improve the structural stability of the entire barrel 1, because the welding is performed on the outside, so that the internal pressure can be better borne and the deformation or damage caused by the change of the internal pressure can be reduced; the outer surface welding can more easily realize the inspection and quality control of the weld, thereby providing a stronger sealing performance to prevent the leakage of the internal medium. At the same time, the outer surface welding makes the welding part easier to detect and evaluate, which is convenient for regular maintenance and necessary repair work. The outer surface welding can also reduce the risk of fatigue cracks caused by welding defects. Welding defects are one of the key factors affecting the fatigue performance of structural parts, and the outer surface welding provides a larger space for welding operations, which may reduce the generation of welding defects; and the outer surface welding is usually easier to be manufactured in a factory, which can realize standardized, assembled and automated production, and improve production efficiency; the outer surface welding also helps to distribute stress more evenly, avoid local excessive stress concentration, and thus improve the durability of the overall structure.

[0037] like Figure 3-4As shown, as an optional embodiment of the present case, the chamber partition 3 includes a connecting ring 31 and a partition body 32; the two ends of the connecting ring 31 in the axial direction are respectively sealed connected to the two adjacent sub-cylinder bodies 11; the partition body 32 is sealed connected to the inner wall of the connecting ring 31.

[0038] It should be noted that by setting the connecting ring 31 and the partition body 32, the structural strength of the chamber partition 3 can be enhanced, so that the connection between the chamber partition 3 and the adjacent sub-cylinder body 11 is better sealed and firm, which can enable the gas storage tank to better withstand internal pressure and external forces, and reduce the risk of deformation and failure caused by pressure changes or external forces.

[0039] like Figure 3-4 As shown, as an optional embodiment of the present case, the two axial ends of the connecting ring 31 have overlapping portions with the corresponding end edges of the sub-tube body 11.

[0040] It should be noted that, by providing the connecting ring 31, there can be more overlapping portions between the chamber partition 3 and the end edge of the sub-barrel body 11, thereby enhancing the connection strength and structural stability between two adjacent sub-barrel bodies 11. Compared with the direct connection to the inner wall of the sub-barrel body 11 only through a circular plate, in this case, due to the presence of the connecting ring 31, the connecting ring 31 can increase the overlapping area between the chamber partition 3 and the sub-barrel body 11, and facilitate the pre-installation between the chamber partition 3 and the sub-barrel body 11. During welding, there is no need to manually hold the chamber partition 3, thereby reducing the difficulty of welding. Even if there is a gap between the inner wall of the connecting ring 31 of the chamber partition 3 and the outer wall of the sub-barrel body 11, it will not affect the sealing of the welded connection too much.

[0041] like Figure 3-4 As shown, as an optional embodiment of the present case, the partition body 32 and the connecting ring 31 are integrally formed or annularly welded, so as to ensure the sealing performance of the gas storage tank at the chamber partition 3.

[0042] As an optional embodiment of the present case, the outer diameter of the connecting ring 31 is larger than the outer diameter of the sub-barrel body 11 , and the inner diameter of the connecting ring 31 is smaller than or equal to the outer diameter of the sub-barrel body 11 .

[0043] It should be noted that, when the outer diameter of the connecting ring 31 is larger than the outer diameter of the sub-barrel body 11, and the inner diameter of the connecting ring 31 is smaller than the outer diameter of the sub-barrel body 11, an annular step portion 311 can be opened on the outer wall of the end of the sub-barrel body 11, so that the inner wall of the connecting ring 31 can fit and overlap with the outer wall of the corresponding sub-barrel body 11, and then the annular seam is welded. Such a design can make a connection step between the chamber partition 3 and the sub-barrel body 11, thereby improving the connection sealing between the chamber partition 3 and the sub-barrel body 11; when the outer diameter of the connecting ring 31 is larger than the outer diameter of the sub-barrel body 11, and the inner diameter of the connecting ring 31 is equal to the outer diameter of the sub-barrel body 11, it is not necessary to open the annular step portion 311 on the outer wall of the end of the sub-barrel body 11, which is beneficial to reducing the manufacturing cost of the gas storage tank.

[0044] like Figure 3-4 As shown, as an optional embodiment of the present case, the axial end of the connecting ring 31 is provided with an annular step portion 311 which is matched and connected with the axial end of the sub-barrel body 11, one side of the annular step portion 311 is in contact with the end face of the sub-barrel body 11, and the other side of the annular step portion 311 is in contact with the outer circumferential surface of the sub-barrel body 11, which can realize the locking and limiting between the chamber partition 3 and the sub-barrel body 11 on the one hand, and increase the contact area between the chamber partition 3 and the sub-barrel body 11 on the other hand, and increase a connection angle, thereby improving the sealing between adjacent sub-chambers 111 of the gas storage tank and between the gas storage tank and the outside world.

[0045] like Figure 3-4 As shown, as an optional embodiment of the present case, the partition body 32 is spherical, thereby increasing the contact area between the gas on the inner wall of the storage tank and the partition body 32, so that the force is more uniform, which can reduce stress concentration and improve the structural strength and stability of the gas tank; the spherical partition body 32 can withstand higher pressure under the condition of the same wall thickness compared to the flat bottom due to the characteristics of its geometric shape, which makes the gas tank have a higher safety factor.

[0046] like Figure 3-4 As shown, as an optional embodiment of the present case, the head 2 and the barrel 1 are connected by annular seam welding or formed in one piece, and there are multiple options.

[0047] like Figure 3-4 As shown, as an optional embodiment of the present case, the chamber partition 3 and one of the sub-cylinder bodies 11 are seamlessly formed as one piece, that is, the chamber partition 3 is the head 2 of the sub-cylinder body 11.

[0048] like Figure 3-4As shown, as an optional embodiment of the present case, the sub-cylinder bodies 11 include two, and one of the sub-cylinder bodies 11 is longer than the other sub-cylinder body 11, thereby forming two sub-chambers 111 of different volumes, one large and one small, so as to cope with different gas supply requirements.

[0049] Further, such as Figure 3-4 As shown, each of the sealing heads 2 is provided with a connector 4, which is connected to the air suspension system or other systems through the connector 4, so as to facilitate installation and disassembly.

[0050] Furthermore, the connector 4 is used to be connected to an electromagnetic valve, so as to control the ventilation volume at the connector 4.

[0051] Furthermore, the barrel 1 includes two heads 2, and the connectors 4 on the two heads 2 are different, so as to connect different systems to meet different connection requirements, so that the two sub-chambers 111 do not interfere with each other, thereby ensuring the stability of the use of the gas source.

[0052] Furthermore, the gas storage tank of the present invention can be used not only in vehicles, but also in other fields where multiple chambers are required.

[0053] Furthermore, the dual-chamber gas storage tank in this case can use the mounting bracket of the previous single-chamber gas tank, and the mounting bracket can be omitted to save costs.

[0054] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a vehicle, including the gas storage tank, so that the vehicle with the gas storage tank is within the protection scope of this case.

[0055] In summary, the utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
