Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to an integrated storage tank structure, an anti-collision beam and a vehicle. Background Art

[0002] Air suspension systems use air tanks to store compressed air, providing air to the suspension system when needed. These tanks are typically located under or at the rear of the vehicle and connect to the air pressure sensor and air pump in the suspension system. When the vehicle's suspension height needs to be adjusted, the air pump pumps compressed air into the tank, which is then transferred via air delivery lines to the suspension airbags or cylinders, adjusting the vehicle's ride height. This air tank allows the air suspension system to adjust the suspension height more quickly and precisely, improving ride comfort and stability.

[0003] Currently, the gas tanks used in automotive air suspension systems are generally circular and have a relatively regular shape. However, due to the limited space available in the vehicle body, these round tanks cannot fully utilize the available space, resulting in limited placement and a failure to meet customer needs. Furthermore, other structural components of the vehicle body, such as the anti-collision beam, occupy a relatively large volume and are hollow within. Integrating the gas tank with these components could reduce component costs, allowing the product to function both as a gas tank for gas storage and as a structural component, such as the anti-collision beam. Therefore, there is a need to address the issue of utilizing the vehicle body's inherent structure as a gas tank for the air suspension system. Utility Model Content

DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0025] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0026] See Figures 1 to 4The utility model provides an integrated storage tank structure, including a hollow anti-collision beam body 1, a pair of baffles 11 are provided at both ends of the anti-collision beam body 1, so that the internal hollow structure of the anti-collision beam body 1 forms a closed air storage chamber 2; at least one reinforcing rib 21 is provided in the air storage chamber 2, and the reinforcing rib 21 is arranged along the arrangement direction of the anti-collision beam body 1 (that is, the reinforcing rib 21 is in the inner cavity of the anti-collision beam body 1, and since the anti-collision beam is arranged along the transverse direction of the vehicle body, the reinforcing rib 21 is arranged along or parallel to the transverse direction of the vehicle body). The contact edge of each reinforcing rib 21 with the inner wall of the air storage chamber 2 is set to an R-angle structure 211 to improve the connection strength between the reinforcing rib 21 and the inner wall of the air storage chamber 2.

[0027] Therefore, the integrated tank structure of the present invention incorporates a pair of baffles 11 at both ends of the anti-collision beam body 1, creating a sealed air storage chamber within the hollow structure of the anti-collision beam body 1, which serves as the air storage tank for the suspension system. This changes the previous practice of requiring a separate air storage tank for the suspension system, which was limited by the space available in the vehicle body. The present invention utilizes the structure of the anti-collision beam body 1 to reduce equipment investment while improving vehicle body layout space utilization. Furthermore, the anti-collision beam body 1 is typically formed through processes such as extrusion, bending, and machining, which significantly reduces its strength. The reinforcing ribs 21 ensure the strength of the air storage tank.

[0028] The aforementioned R-angle structure 211: The R-angle is a rounded corner design formed at the center of the edge. The function of the R-angle is to reduce stress concentration at the edge and improve the strength and stability of the part. The size of the R-angle is generally determined by the radius. Common R-angle radii are 1mm, 3mm, 5mm, etc. Generally speaking, the R-angle is a rounded corner design formed at the edge, which is mainly used to reduce stress concentration and improve the strength and stability of the part.

[0029] In one embodiment of the present invention, two reinforcing ribs 21 are evenly distributed within the gas storage chamber 2. The transverse ends of each reinforcing rib 21 correspond to the ends of the gas storage chamber 2 and are spaced apart by a distance L of 30 ± 5 mm. This ensures that the distribution of gas within the gas storage chamber 2 is not restricted by the reinforcing ribs 21 and that gas mixing is evenly distributed at both ends of the gas storage chamber 2.

[0030] In one embodiment of the present invention, the anti-collision beam body 1 comprises a top wall 12, a front wall 13, a bottom wall 14, and a rear wall 15, which are connected in sequence. The front wall 13 is the impact side, and both ends of the front wall 13 extend laterally, with an extension distance of 15±5mm. When the vehicle is involved in a side collision, the extended portions of the front wall 13 first contact the impacting object, acting as a buffer, reducing the impact strength of the air storage chamber 2, and improving the anti-collision capability of the anti-collision beam body when used as an air storage tank.

[0031] In one embodiment of the present invention, an air nozzle 22 is provided on the bottom wall 14 of the anti-collision beam body 1, corresponding to the air storage chamber 2, for communicating with the suspension system. The air nozzle 22 comes in various types and sizes, allowing it to connect to the suspension system in different applications to ensure proper operation and smooth gas flow. The air storage chamber 2 can be used to store air for the vehicle's suspension system. By adjusting the pressure and volume of the gas within the air storage chamber 2, the suspension system's shock absorption and support performance can be adjusted, enhancing the vehicle's driving comfort and stability. The air storage chamber 2 absorbs and mitigates vibrations and bumps generated by the suspension system during driving, providing a smoother ride and reducing discomfort for the driver and passengers. The air storage chamber 2 can also act as a gas spring, improving the suspension system's response speed. When encountering bumpy or uneven roads, the air storage chamber 2 can quickly release or absorb gas, allowing the suspension system to more quickly adapt to changing road conditions and improving the vehicle's handling performance. By rationally utilizing the gas pressure and volume within the air storage chamber 2, energy consumption within the suspension system can be reduced, improving the vehicle's fuel economy and thus achieving energy-saving and environmental benefits.

[0032] To achieve the above-mentioned and other related objectives, in one embodiment of the present invention, an anti-collision beam includes an integrated storage tank structure and energy absorption boxes 3 disposed at both ends of the anti-collision beam body 1. The integrated storage tank structure includes the anti-collision beam body 1, a pair of baffles 11, and at least one reinforcing rib 21. The pair of baffles 11 are correspondingly disposed at both ends of the anti-collision beam body 1, so that the internal hollow structure of the anti-collision beam body 1 forms a sealed air storage chamber 2. The reinforcing rib 21 is disposed within the air storage chamber 2 and arranged transversely along the air storage chamber 2. The rear wall 15 of the anti-collision beam body 1 serves as the mounting side, and the front wall 13 of the anti-collision beam body 1 serves as the impact side. Each energy absorption box 3 is mounted on the mounting side of the anti-collision beam body 1 and is aligned with the mounting side, so that the top of the energy absorption box 3 extends horizontally toward the impact side and overlaps the top wall 12 of the anti-collision beam body 1. Each energy absorption box 3 is provided with a mounting plate 31 on the side away from the anti-collision beam body 1, and the mounting plate 31 is threadedly fixed to the vehicle frame. A threaded sleeve 4 for mounting a trailer hook is horizontally passed through the anti-collision beam body 1 .

[0033] To achieve the above-mentioned object and other related objects, in one embodiment of the present invention, a vehicle includes the above-mentioned anti-collision beam.

[0034] To sum up, an integrated storage tank structure of the present invention is to provide a pair of baffles 11 at both ends of the anti-collision beam body 1, so that the internal hollow structure of the anti-collision beam body 1 forms a closed air storage cavity, which is used as an air storage tank for the suspension system, thereby realizing the integration of the air storage tank into the anti-collision beam structure of the vehicle body. At the same time, because the anti-collision beam is formed by extrusion, bending, machining and other processes, its strength is reduced. In order to ensure the strength of the air storage tank, a reinforcing rib plate 21 is added to the inside of the air storage cavity 2, and the reinforcing rib 21 is provided with an R-angle structure 21 to increase the strength.

[0035] The utility model provides an anti-collision beam, comprising the above-mentioned integrated storage tank structure and energy absorption boxes 3 provided at both ends of the anti-collision beam body 1. Each energy absorption box 3 is arranged on the installation side of the anti-collision beam body 1, and the installation sides are correspondingly fitted, so that the top of the energy absorption box 3 extends horizontally toward the impact side and overlaps the top wall 12 of the anti-collision beam body 1. A mounting plate 31 is provided on the side of each energy absorption box 3 away from the anti-collision beam body 1, and the mounting plate 31 is fixedly connected to the vehicle frame through threads. A threaded sleeve 4 for installing a trailer hook is provided horizontally through the anti-collision beam body 1. An integrated arrangement is achieved, and while the anti-collision beam plays its own anti-collision role in the vehicle, it can be connected to the suspension system through the air nozzle 22, which can reduce the investment in equipment costs while improving the space utilization rate of the vehicle body. According to the reserved space, a special-shaped (non-circular) air storage tank is designed to effectively fill the vehicle body space.

[0036] The utility model also provides a vehicle with the aforementioned integrated storage tank structure.
