Description

TECHNICAL FIELD

[0001] The utility model belongs to fuel tank guard plate technical field especially relates to a fuel tank guard plate reinforcing structure. BACKGROUND

[0002] In the design field of fuel tank guard plate, the existing guard plate mainly presents two structural shapes. One is a rectangular geometric body plate structure casted in one piece. In order to ensure sufficient structural strength, the thickness of the plate body is often much larger than that of other types of guard plates. However, this results in a significant increase in weight, which not only consumes more energy during the operation of vehicles and other equipment, increasing operating costs, but also greatly limits the use of heavy guard plates in some applications with strict weight restrictions, such as aerospace and electric vehicles.

[0003] The other is a plate body structure with reinforcing beams, which meets the demand for lightweight to some extent. However, there are obvious defects in the placement of the reinforcing beams. When the reinforcing beams are placed on the outside of the guard plate (away from the surface of the guard plate near the fuel tank), they protrude outward, so in actual use, foreign objects on the road surface during vehicle travel, such as protruding stones and hard objects in potholes, will directly collide with the reinforcing beams on the outside. This frequent collision not only causes damage to the reinforcing beams themselves, but also prevents the reinforcing beams from fully exerting their reinforcing function, seriously affecting the protective effect of the guard plate on the fuel tank.

[0004] When the reinforcing beams are placed on the inside of the guard plate (close to the surface of the guard plate near the fuel tank), although direct collisions with external foreign objects are avoided, new problems arise. Once the entire guard plate deforms due to external impact, the reinforcing beams on the inside will quickly occupy the space originally used for buffering. At this time, the reinforcing beams will first collide sharply with the fuel tank, posing a serious threat to the safety of the fuel tank and possibly causing the fuel tank to rupture, leak, and other dangerous situations, greatly reducing the safety and reliability of the fuel tank.

[0005] In summary, the existing fuel tank guard plate structure has many problems in terms of structural strength, weight control, and effective protection of the fuel tank, and a new guard plate reinforcing structure is urgently needed to solve these problems.

[0006] Therefore, it is necessary to invent a fuel tank guard plate reinforcing structure. UTILITY MODEL CONTENTS

[0025] As shown in the accompanying Figure 1 to the accompanying Figure 3 drawings:

[0026] The utility model provides a kind of fuel tank guard plate reinforcing structure, including guard plate main body 1, arc plate side shift 2, transverse recess 3, longitudinal recess 4, transverse reinforcing beam 5, first longitudinal reinforcing beam 6, second longitudinal reinforcing beam 7, mounting hole 8, connecting hole 9 and positioning hole 10, the guard plate main body 1 and arc plate side shift 2 are integrally set together, the guard plate main body 1 and arc plate side shift 2 are provided with transverse recess 3, wherein the guard plate main body 1 is provided with two longitudinal recess 4, first longitudinal reinforcing beam 6 and second longitudinal reinforcing beam 7 are respectively assembled in two longitudinal recess 4;The transverse reinforcing beam 5 is assembled in the transverse recess 3, the guard plate main body 1, transverse reinforcing beam 5, first longitudinal reinforcing beam 6 and second longitudinal reinforcing beam 7 are provided with connecting hole 9, the guard plate main body 1 is provided with positioning hole 10;The arc plate side shift 2 is provided with mounting hole 8.

[0027] Further, the guard plate main body 1 and the arc plate side shift 2 are made by integral casting process, and high-strength aluminum alloy material is selected. This material has good strength and light weight. After casting, the arc plate side shift 2 is shaped by precise inward bending process. The arc plate side shift 2 is located on both sides of the fuel tank, and its shape corresponds to the profile of the side of the fuel tank. There is a buffer space between them, which can provide all-round protection for the side of the fuel tank. The guard plate main body 1 is located below the fuel tank, and it has a buffer space. Together, they form a complete guard plate structure, seamlessly connecting to provide a stable and reliable protective barrier for the fuel tank.

[0028] Further, the guard plate main body 1 and the arc plate side shift 2 are provided with transverse recesses 3, and the transverse recesses 3 are crosswise arranged with two longitudinal recesses 4. The two longitudinal recesses 4 are parallel to each other and evenly distributed on the guard plate main body 1. These recesses are formed by mechanical processing, and the depth and width of the recesses are accurately calculated to fit the reinforcing beams installed later. The cross design of the transverse recesses 3 and the longitudinal recesses 4 forms a stable grid structure, effectively enhancing the overall strength and rigidity of the guard plate.

[0029] Further, the guard plate main body 1, the transverse reinforcing beam 5, the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7 are fixedly connected by fasteners. High-strength stainless steel bolts and nuts are selected as fasteners. This material has good anti-corrosion performance, which can ensure long-term stable use in complex environment. The bolts are sequentially inserted through the connecting holes 9 pre-formed on the guard plate main body 1, the transverse reinforcing beam 5, the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7, and then the nuts are tightened, so that the four are tightly fixed together. The position of the connecting hole 9 is accurately designed to ensure that the components can work cooperatively after connection, fully exerting the reinforcing effect.

[0030] Furthermore, the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7 are parallel to each other and have identical structural shapes. The transverse reinforcing beam 5, the first longitudinal reinforcing beam 6, and the second longitudinal reinforcing beam 7 all adopt a "C"-shaped steel structure and are made of high-quality carbon structural steel. The "C"-shaped structural design significantly improves the bending and compressive strength of the reinforcing beams without adding excessive weight. The dimensions of each reinforcing beam are customized according to the dimensions of the main body of the guard plate 1 and the lateral displacement of the arc plate 2, as well as the specifications of the recessed groove, to ensure a perfect fit.

[0031] Furthermore, both the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7 have recessed clearances corresponding to the transverse reinforcing beam 5, which are manufactured using a stamping process. When the transverse reinforcing beam 5 is assembled with the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7, the recessed clearances ensure that the transverse reinforcing beam 5 is embedded within them, making the fit between the reinforcing beams tighter and preventing mutual interference. The transverse reinforcing beam 5, the first longitudinal reinforcing beam 6, and the second longitudinal reinforcing beam 7 are installed within the transverse recessed groove 3 and the longitudinal recessed groove 4, and do not protrude beyond the main structure of the protective plate, ensuring the overall flatness of the protective plate. This does not affect the protective performance of the protective plate and prevents the risk of impact caused by protruding parts.

[0032] Installation process and working principle

[0033] Installation process:

[0034] Prepare all components in advance. Ensure that all components are undamaged and undeformed, especially the main body of the guard plate 1 and the arc plate lateral displacement 2, whose one-piece casting structure should be intact and the surface free of defects. Align the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7 with the two longitudinal recesses 4 on the main body of the guard plate 1 and slowly insert them. Since the depth and width of the longitudinal recesses 4 are precisely calculated and machined according to the reinforcing beams, the reinforcing beams should fit tightly in the grooves and remain parallel to each other. Install the transverse reinforcing beam 5 into the transverse recesses 3 on the main body of the guard plate 1 and the arc plate lateral displacement 2. During installation, pay attention to the positional relationship between the transverse reinforcing beam 5 and the longitudinal reinforcing beams 6 and 7, ensuring that the clearance recess between the first longitudinal reinforcing beam 6 and the second longitudinal reinforcing beam 7 accurately corresponds to the transverse reinforcing beam 5, so that the transverse reinforcing beam 5 can be smoothly inserted into the clearance recess, achieving a tight fit between the reinforcing beams and avoiding interference.

[0035] Using pre-prepared high-strength stainless steel bolts, sequentially pass them through the connecting holes 9 on the main body of the guard plate 1, the transverse reinforcing beam 5, the first longitudinal reinforcing beam 6, and the second longitudinal reinforcing beam 7. When inserting the bolts, ensure they are perpendicular to the surfaces of each component to avoid tilting and resulting in an insecure connection. After the bolts are in place, screw on the nuts on the other side and gradually tighten them using a suitable tool (such as a wrench). Tighten the nuts in a specific order and according to the required torque to ensure even stress distribution on all components, ensuring they are tightly fixed together and fully utilizing the reinforcing effect of the reinforcing beams on the main body of the guard plate.

[0036] Move the entire protective plate with the reinforcing beam installed to the fuel tank mounting position. Using locating pins or other positioning tools, accurately determine the installation position of the protective plate on the vehicle or equipment through the positioning holes 10 on the protective plate body 1, ensuring that the protective plate body 1 is located below the fuel tank, the arc plate lateral displacement 2 is located on both sides of the fuel tank, and a suitable buffer space is reserved between the protective plate and the fuel tank. Using bolts or other connectors, fix the protective plate to the corresponding mounting part of the vehicle or equipment through the mounting holes 8 on the arc plate lateral displacement 2, completing the installation of the entire fuel tank protective plate reinforcement structure.

[0037] Working principle:

[0038] The overall structure formed by the main body of the protective plate 1 and the lateral arc plate 2 provides all-round physical protection for the fuel tank. The main body of the protective plate 1, located below the fuel tank, effectively blocks impacts from road debris such as stones and protrusions, preventing damage to the bottom of the fuel tank. The lateral arc plate 2, located on both sides of the fuel tank, resists side impacts and scratches, protecting the sides of the fuel tank from damage. The grid structure formed by the intersection of the transverse recessed grooves 3 and the longitudinal recessed grooves 4, along with the transverse reinforcing beams 5, the first longitudinal reinforcing beam 6, and the second longitudinal reinforcing beam 7 installed within it, greatly enhances the overall strength and rigidity of the protective plate. When subjected to external impacts, the protective plate can better disperse and withstand the impact force, reducing deformation caused by impacts, thus providing more reliable protection for the fuel tank. The buffer spaces reserved between the main body of the protective plate 1 and the bottom of the fuel tank, and between the lateral arc plate 2 and the sides of the fuel tank, act as a buffer when the protective plate is impacted. When an external force is applied to the skid plate, the skid plate can undergo a certain degree of elastic deformation within the buffer space to absorb part of the impact force, preventing the impact force from being directly transmitted to the fuel tank and reducing the risk of damage to the fuel tank due to impact.

[0039] The reinforcing beam is installed within the recessed groove and does not protrude from the main structure of the guard plate, effectively preventing direct collision between the reinforcing beam and foreign objects below. During vehicle operation, even if there are foreign objects on the road, they will only come into contact with the main body of the guard plate first, protecting the reinforcing beam and allowing its reinforcing function to continue to operate.

[0040] Meanwhile, the inner reinforcing beam will not quickly occupy the buffer space due to the deformation of the protective plate and collide sharply with the fuel tank, ensuring that the fuel tank can be safely and reliably protected under various circumstances, thus improving the safety and reliability of the fuel tank.

[0041] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
