Description

Technical Field

[0001] This application relates to the field of automobile chassis, and in particular to a protective structure for an automobile chassis fuel tank. Background Technology

[0002] The car chassis is the supporting structure of a car, and the fuel tank is installed at the rear bottom of the chassis. When driving on rough roads, the car may jump a short distance and then land on the ground, or the chassis may be hit by multiple stones, resulting in impact and scraping of the chassis. The fuel tank may also be deformed or damaged as a result. In order to protect the fuel tank, a protective structure is needed to protect the fuel tank on the chassis.

[0003] In existing technologies, a protective plate is added to the fuel tank area of ​​the car chassis to protect the fuel tank. However, the existing protective plate structure has the following problems: While the existing technology uses a protective plate around the fuel tank to absorb impacts and scratches from stones and sharp objects, the protective plate can deform and break. Even after deformation and breakage, the protective plate still exerts pressure on the fuel tank, causing it to deform further. Furthermore, the broken parts of the protective plate may scratch the fuel tank's outer shell. Additionally, contact between the protective plate and stones or sharp objects may generate sparks, which, combined with the high temperatures from metal friction, could cause the fuel tank to ignite, indicating poor flame retardancy.

[0004] There is currently no effective solution to the problem of poor flame retardancy in the existing chassis's fuel tank protection structure. Utility Model Content

[0005] This invention provides a protective structure for a car chassis fuel tank to solve the problem of poor flame retardancy in existing chassis fuel tank protective structures.

[0006] This utility model provides a protective structure for an automobile chassis fuel tank, including a chassis fuel tank frame, a protective plate, a curved panel, a connecting assembly, and a cooling plate. The protective plate absorbs impacts to the fuel tank; a front baffle is mounted on the first side of the protective plate, and a rear baffle is mounted on the second side. The curved panel is arched, solid, and has a smooth bottom surface. The connecting assembly connects and secures the chassis fuel tank frame, the protective plate, and the curved panel. The cooling plate is fixed to the top of the protective plate, located between the curved panel and the protective plate, with a gap between the top of the cooling plate and the bottom of the curved panel. The cooling plate is a hollow metal plate, filled with flame-retardant cotton, and contains a flame-retardant liquid to soak the cotton.

[0007] Furthermore, the protective panel is made of aluminum alloy.

[0008] Furthermore, the connecting assembly includes two symmetrically arranged Z-shaped plates, each with several mounting holes. The chassis fuel tank bracket is connected to the mounting holes on the top outer side of the two Z-shaped plates via bolts. The protective plate is connected to the mounting holes on the bottom inner side of the two Z-shaped plates via bolts. The curved panel is connected to the mounting holes on the top inner side of the two Z-shaped plates via bolts.

[0009] Furthermore, the connecting assembly includes two Z-shaped plates. The first ends of the two Z-shaped plates are symmetrically welded to the inner walls of the outer edges of the protective plate and the third and fourth sides of the curved panel, respectively. The second ends of the two Z-shaped plates are symmetrically welded to the chassis fuel tank frame, respectively.

[0010] Furthermore, the outer shell of the cooling plate is equipped with a filling port for filling with flame-retardant liquid.

[0011] Furthermore, the first side of the protective plate has a front baffle integrally formed, and the second side of the protective plate has a rear baffle integrally formed.

[0012] Furthermore, a front baffle is welded to the first side of the protective plate, and a rear baffle is welded to the second side of the protective plate.

[0013] Furthermore, ribs are installed at the connection between the protective plate and the front baffle.

[0014] Furthermore, ribs are installed at the connection between the protective plate and the rear baffle.

[0015] Furthermore, both the front and rear baffles have prism panels fixed to their outer walls, with the center of the prism panels protruding.

[0016] Compared with related technologies, the automobile chassis fuel tank protection structure provided in this utility model has the following beneficial effects:

[0017] 1. After the protective plate is broken, the sharp protrusions of the protective plate will scratch the cooling plate. At this time, the sharp protrusions will be poured with flame-retardant liquid and wrapped with flame-retardant cotton, thereby quickly cooling the sharp protrusions of the protective plate, as well as the protective plate, curved panel and connecting components, thus avoiding the combustion of the fuel tank caused by high temperature and sparks.

[0018] 2. When driving in rough road conditions, if the chassis is impacted by sharp objects such as stones, the protective plate will first come into contact with the sharp objects to offset most of the impact force, thereby reducing the force on the fuel tank.

[0019] 3. The front and rear baffles can guide sharp or blunt objects such as stones, guiding them to contact the bottom of the protective plate and thus avoiding impact with the side of the protective plate, making more effective use of the protective plate's performance.

[0020] 4. When the protective plate deforms and breaks under external force, it may produce sharp upward protrusions. If these sharp protrusions tend to move towards the fuel tank, they will be deflected away from the fuel tank by the smooth curved panel on the bottom, thus protecting the fuel tank.

[0021] 5. Most of the impact force borne by the protective plate will be transferred to the chassis fuel tank frame through the Z-shaped plate. Since the chassis fuel tank frame has good load-bearing capacity, the impact force is transferred and the fuel tank is protected.

[0030] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0031] Unless otherwise defined, the technical or scientific terms used in this application shall have the general meaning understood by one of ordinary skill in the art to which this application pertains. Words such as “a,” “an,” “an,” “the,” “the,” and “these” used in this application do not indicate quantitative limitation and may be singular or plural. The terms “comprising,” “including,” “having,” and any variations thereof used in this application are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or modules (units) is not limited to the listed steps or modules (units) but may include steps or modules (units) not listed, or may include other steps or modules (units) inherent to these processes, methods, products, or devices. Words such as “connected,” “linked,” and “coupled” used in this application are not limited to physical or mechanical connections but may include electrical connections, whether direct or indirect. “Multiple” used in this application refers to two or more. “And / or” describes the relationship between related objects, indicating that three relationships may exist; for example, “A and / or B” can represent: A alone, A and B simultaneously, and B alone. Normally, the character " / " indicates that the objects before and after it are in an "or" relationship. The terms "first," "second," "third," etc., used in this application are merely to distinguish similar objects and do not represent a specific order of objects.

[0032] The "first side, second side, third side, and fourth side" referred to in this article represent four different directions on a plane, which can also correspond to the directions of east, south, west, and north.

[0033] Please see Figure 1 This utility model provides a protective structure for an automobile chassis fuel tank, including a chassis fuel tank bracket 1, a protective plate 2, a curved plate 7, a connecting assembly 11, and a cooling plate 6. The chassis fuel tank bracket 1 is part of the existing chassis structure and is located near the fuel tank, providing good load-bearing capacity.

[0034] The protective plate 2 is used to absorb the impact on the fuel tank. When driving in harsh road conditions, if the chassis encounters sharp objects such as stones, the protective plate 2 will first contact the sharp object to offset most of the impact force, thus reducing the force on the fuel tank. The protective plate 2 can be made of metal to increase its protective strength, or it can be made of aluminum alloy. Aluminum alloy has excellent impact resistance and shock absorption capabilities, providing better protection for the fuel tank, and it is also lighter in weight.

[0035] Please see Figure 2A front baffle 4 is installed on the first side of the protective plate 2, and a rear baffle 5 is installed on the second side of the protective plate 2. The front baffle 4 and the rear baffle 5 can guide sharp objects such as stones or blunt objects, guiding the objects to contact the bottom of the protective plate 2, thereby avoiding impact between the objects and the sides of the protective plate 2, and making more effective use of the performance of the protective plate 2.

[0036] The installation methods for the front baffle 4 and the rear baffle 5 can also be varied. For example, the front baffle 4 can be integrally formed on the first side of the protective plate 2, and the rear baffle 5 can be integrally formed on the second side of the protective plate 2. The advantage of this installation is that it facilitates disassembly and maintenance; if only a portion is damaged, only the damaged part can be replaced, reducing maintenance costs. Alternatively, the front baffle 4 can be welded to the first side of the protective plate 2, and the rear baffle 5 can be welded to the second side of the protective plate 2. The advantage of this installation is that the structure is more stable and will not wobble.

[0037] To further enhance the stability of the front baffle 4 and the rear baffle 5, structural strength can be increased by adding plate reinforcement 3. For example, plate reinforcement 3 can be provided at the connection between the protective plate 2 and the front baffle 4, and at the connection between the protective plate 2 and the rear baffle 5.

[0038] Please see Figure 2 and Figure 6 The curved panel 7 is arched and solid, with a smooth bottom surface. The arched shape resembles the arch of a bridge, and the solid structure enhances the strength of the curved panel 7. The smooth bottom surface is a crucial technical feature. When the protective plate 2 deforms and breaks under external force, it may produce sharp, upward protrusions. If these protrusions tend to move towards the fuel tank, the smooth bottom surface of the curved panel 7 will guide them away from the fuel tank, thus protecting it.

[0039] Please see Figure 3 and Figure 4The connecting assembly 11 is used to connect and fix the chassis fuel tank frame 1, the protective plate 2, and the curved panel 7. For example, the connecting assembly 11 includes two symmetrically arranged Z-shaped plates 111, each of which has several mounting holes 112. The chassis fuel tank frame 1 is connected to the mounting holes 112 on the top outer side of the two Z-shaped plates 111 by bolts. The protective plate 2 is connected to the mounting holes 112 on the bottom inner side of the two Z-shaped plates 111 by bolts. The curved panel 7 is connected to the mounting holes 112 on the top inner side of the two Z-shaped plates 111 by bolts. In addition, other connection methods are possible. For example, the connecting assembly 11 includes two Z-shaped plates 111, the first ends of which are symmetrically welded to the inner walls of the outer edges of the protective plate 2 and the curved panel 7 on the third and fourth sides, respectively. The second ends of which are symmetrically welded to the chassis fuel tank frame 1, respectively. The advantage of this installation is that most of the impact force borne by the protective plate 2 will be transferred to the chassis fuel tank frame 1 through the Z-shaped plate 111. Since the chassis fuel tank frame 1 has good load-bearing capacity, the impact force is transferred and the fuel tank is protected.

[0040] Please see Figure 2 and Figure 5 The cooling plate 6 is fixed to the top of the protective plate 2, located between the curved panel 7 and the protective plate 2. A gap is left between the top of the cooling plate 6 and the bottom of the curved panel 7. The cooling plate 6 is a hollow metal plate, filled with flame-retardant cotton. Flame-retardant liquid is placed inside the cooling plate 6 to soak the flame-retardant cotton. The flame-retardant cotton is a fireproof material synthesized from various polyurethanes with added flame retardants. The flame-retardant liquid can be water or other flame-retardant liquids. The advantage of this installation is that when the protective plate 2 is broken, the sharp protrusions of the protective plate 2 will cut through the cooling plate 6. At this time, the sharp protrusions will be poured with flame-retardant liquid and wrapped by flame-retardant cotton, thereby quickly cooling the sharp protrusions of the protective plate 2, as well as the protective plate 2, the curved panel 7, and the connecting component 11, thus preventing the fuel tank from burning due to high temperature and sparks.

[0041] To facilitate the replacement of the flame retardant liquid, a sealable opening can be provided on the cooling plate 6. For example, the outer shell of the cooling plate 6 is provided with a filling port 61, which is used to fill the flame retardant liquid.

[0042] To improve the guiding effect of the front baffle 4 and the rear baffle 5, their shapes can be modified. For example, a prism panel 8 can be fixed to the outer wall of both the front baffle 4 and the rear baffle 5, with a central protrusion in the prism panel 8. The advantage of this is that if an object contacts the central protrusion of the prism panel 8, the object's trajectory is deflected to the left and right by the diversion effect of the central protrusion, thus avoiding excessive contact in the center and increasing safety.

[0043] It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it.

Those skilled in the art can apply this application to other similar situations based on these drawings without any creative effort. Furthermore, it is understood that although the work done in this development process may be complex and lengthy, for those skilled in the art, certain design, manufacturing, or production modifications made based on the technical content disclosed in this application are merely conventional technical means and should not be considered as insufficient disclosure of this application.
