Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a fuel tank protective plate and a vehicle. Background Technology

[0002] The fuel tank is used to store fuel. If foreign objects splash into the fuel tank while the vehicle is in motion, it can damage the fuel tank and cause fuel leaks. Therefore, a fuel tank protection plate is needed to protect the fuel tank from the bottom of the vehicle.

[0003] In the existing technology, there are two types of fuel tank protection plates. One type is a metal protection plate, such as DC01 or DC51 steel plate or AL5182 aluminum plate. However, metal protection plates are heavy and have high component costs. The other type is a non-metallic protection plate, but the protection level is weak and the puncture resistance is insufficient.

[0004] Therefore, how to provide a fuel tank protection plate that ensures its protection level while avoiding the problems of large weight and high cost is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a fuel tank protection plate and vehicle that can ensure the protection level while avoiding the problems of large weight and high cost.

[0006] To solve the above-mentioned technical problems, this application provides a fuel tank protection plate, including a plate body, the plate body including a fuel tank mounting part; the plate body is partially provided with a reinforcing layer and forms a reinforcing area, the reinforcing area including the front side areas located at both ends of the fuel tank mounting part.

[0007] Optionally, the plate also includes a protective portion located on one side of the fuel tank mounting portion, and the reinforcing area also includes at least a portion of the area where the protective portion is located.

[0008] Optionally, the reinforcing layer is embedded in the plate body;

[0009] And / or, the reinforcing layer is a non-metallic layer.

[0010] Optionally, the plate is a molded plate, and the reinforcing layer is a CFRT layer.

[0011] Optionally, the plate body is a PP+GF plate;

[0012] And / or, the reinforcing layer is a PP+GF layer, a PC+GF layer, a PET+GF layer, or a PA+GF layer.

[0013] Optionally, a molding layer is provided on both sides of the reinforcing layer, and the thickness of the molding layer is in the range of 1.5mm-2mm.

[0014] Optionally, the thickness of the reinforcing layer is in the range of 1mm-1.5mm.

[0015] Optionally, the thickness of the reinforcing region is in the range of 4mm-6mm.

[0016] Optionally, the thickness of the molded plate is in the range of 3mm-4mm.

[0017] This application also provides a vehicle including the fuel tank protection plate as described above.

[0018] The fuel tank protection plate and vehicle provided in this application have the following technical advantages compared to the prior art:

[0019] The reinforced area includes the front regions at both ends of the fuel tank mounting section. The two ends of the fuel tank mounting section correspond to the two ends of the fuel tank, specifically the two ends on the left and right sides of the vehicle in the width direction when installed. The front of the fuel tank refers to the side facing the front of the vehicle when installed. During vehicle operation, the rotation of the two front wheels will cause foreign objects (such as mud, gravel, etc.) to fly backward and upward. These foreign objects will impact the fuel tank protection plate, specifically the front regions at both ends of the fuel tank protection plate. Therefore, by setting a reinforced layer at the front regions at both ends of the fuel tank protection plate, the structural strength of this area is ensured, reducing the probability of foreign objects flying from the vehicle impacting the fuel tank protection plate and causing it to break. This prevents foreign objects from impacting the fuel tank, provides protection for the fuel tank, and avoids fuel leakage due to fuel tank damage.

[0020] Because the plate is made of non-metallic material, it can effectively reduce the overall weight and cost compared to metal protective plates. Compared to existing non-metallic protective plates, it strengthens the area that is prone to foreign object impact by forming a reinforced zone, thus ensuring the overall structural strength and puncture resistance of the fuel tank protective plate and effectively protecting the fuel tank.

[0021] Furthermore, in this embodiment, a reinforcing layer is provided for areas that are prone to damage and have puncture resistance. This is highly targeted and, compared to a solution that uses a reinforcing layer for the entire larger area, it can reduce weight and cost while ensuring that the performance of the fuel tank protection plate meets the requirements.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This application provides a fuel tank protection plate and a vehicle. The vehicle includes a vehicle body, a fuel tank, and a fuel tank protection plate. The fuel tank protection plate is located at the bottom of the fuel tank and is used to protect the fuel tank from the bottom, preventing fuel leakage caused by the fuel tank rupturing due to collision with foreign objects during vehicle operation.

[0030] like Figure 1 and Figure 2 As shown, the fuel tank protection plate provided in this embodiment includes a plate body 100, which is a non-metallic plate. The plate body 100 includes a fuel tank mounting part 1, which is used to mount a fuel tank. The plate body 100 is partially provided with a reinforcing layer 4 and forms a reinforcing area 3. The reinforcing area 3 includes the front side area located at both ends of the fuel tank mounting part 1.

[0031] The plate 100 is provided with a mounting groove, which is adapted to the bottom of the fuel tank and forms the aforementioned fuel tank mounting part 1. Of course, in this embodiment, the specific structure of the fuel tank mounting part 1 is not limited. For example, the fuel tank mounting part 1 can be formed by a part of the mounting area of ​​the plate 100, and the fuel tank can be installed in the mounting area and fixed to the mounting area.

[0032] like Figure 1 As shown, the plate 100 has a body area 2 and a reinforcing area 3. A reinforcing layer 4 is partially provided on the plate 100 to form the reinforcing area 3. The area of ​​the plate 100 excluding the reinforcing area 3 forms the body area 2. That is, the body area 2 is entirely made of non-metallic material. Compared to the body area 2, the reinforcing area 3 has an additional reinforcing layer 4, which ensures the structural strength and puncture resistance of the reinforcing area 3. The location of the reinforcing area 3 can be specifically set according to the structural strength requirements of the protective plate.

[0033] The reinforced area 3 includes the front areas located at both ends of the fuel tank mounting part 1. The two ends of the fuel tank mounting part 1 correspond to the two ends of the fuel tank, specifically referring to the two ends on the left and right sides in the vehicle width direction when installed. The front side of the fuel tank, such as... Figure 1 The direction indicated by the middle arrow refers to the side facing the front of the vehicle when installed. During vehicle operation, the rotation of the two front wheels will cause foreign objects (such as mud, gravel, etc.) to fly backward and upward. These foreign objects will impact the fuel tank protection plate, specifically the front sides of both ends of the fuel tank protection plate. Therefore, a reinforcing layer 4 is installed on the front areas of both ends of the fuel tank protection plate to ensure the structural strength of this area. This reduces the probability of the fuel tank protection plate being damaged by foreign objects carried by the vehicle, thus preventing foreign objects from impacting the fuel tank and providing protection for the fuel tank, preventing fuel leakage due to fuel tank damage.

[0034] Since the plate 100 is made of non-metallic material, it can effectively reduce the overall weight and cost compared to the metal protective plate solution. Compared with the existing non-metallic protective plates, the reinforcement zone 3 is formed by local reinforcement, which strengthens the structure of the area that is prone to foreign object impact, ensuring the overall structural strength and puncture resistance of the fuel tank protective plate, thereby effectively protecting the fuel tank.

[0035] Furthermore, in this embodiment, a reinforcing layer 4 is provided for areas that are prone to damage and have puncture resistance. This is highly targeted and, compared to a solution that uses reinforcing layer 4 for the entire larger area, it can reduce weight and cost while ensuring that the performance of the fuel tank protection plate meets the requirements.

[0036] like Figure 1 and Figure 2 As shown, the plate 100 also includes a protective part 5, which is located on one side of the fuel tank mounting part 1. This protective part 5 is used to protect the high-voltage wiring harness of the vehicle battery pack from impacts by foreign objects carried by the wheels, preventing damage to the wiring harness. The shape, size, and position of the protective part 5 can be determined according to the arrangement of the high-voltage wiring harness, and no specific restrictions are imposed here.

[0037] The reinforced area 3 also includes at least a portion of the area where the protective part 5 is located. That is, the protective part 5 may have a reinforcing layer 4 in a partial area or the entire area may be reinforced with a reinforcing layer 4 to ensure the structural strength and puncture resistance of the protective part 5, thereby ensuring effective protection of the wiring harness. In other words, the reinforced area 3 of the plate 100 includes the front areas located at both ends of the fuel tank mounting part 1, and at least a portion of the area of ​​the protective part 5.

[0038] Of course, in this embodiment, the plate 100 may only include the fuel tank mounting part 1 for providing protection for the fuel tank, while the protective part 5 can also provide protection for the high-voltage wiring harness, resulting in better protection performance.

[0039] Strengthened Zone 3 Figure 1 The area shown in the red box has a reinforcing layer 4 on the side of the fuel tank mounting part 1 away from the protective part 5, forming a first reinforcing area 31. The reinforcing layer 4 is also provided on the side of the fuel tank mounting part 1 facing the protective part 5 and in the area where the protective part 5 is located, forming a second reinforcing area 32. The reinforcing layer 4 of the second reinforcing area 32 can be an integral structure, which can simplify the molding process.

[0040] like Figure 1 and Figure 2 As shown, the plate 100 is also provided with raised ribs 6, which are arranged in the body area 2 and the reinforcing area 3. The raised ribs 6 enhance the overall structural strength of the plate 100. The location, number, and arrangement of the raised ribs 6 are not limited and can be set according to actual needs. Raised ribs 6 are correspondingly provided in the reinforcing area 3, and raised ribs 6 are provided in the body area 2 as needed to avoid large flat areas, thus ensuring the overall structural strength. Furthermore, as... Figure 1 and Figure 2 As shown, a raised rib 6 is provided on one side of the plate 100, and a groove is formed on the other side of the plate 100. Compared with the solution of forming the raised rib 6 by thickening only one side surface, it can achieve structural reinforcement and also facilitate weight reduction.

[0041] The circumferential edge of the plate 100 is provided with mounting holes 8, which are used to fix it directly or indirectly to the vehicle body by fasteners. At the same time, the fuel tank mounting part 1 is also provided with fixing holes 11, which are used to fix it to the fuel tank by fasteners to ensure the stability of the fuel tank protection plate.

[0042] The plate 100 is also provided with a drainage hole 7 along its thickness direction. When the vehicle is wading through water, water will enter the top of the plate 100. This water can be drained through the drainage hole 7 to avoid water accumulation.

[0043] In this embodiment, there are no restrictions on the specific material, shape, size, etc. of the reinforcing layer 4.

[0044] Preferably, the reinforcing layer 4 is a non-metallic layer. Of course, the reinforcing layer 4 can also be a metallic layer, such as a metal plate or metal mesh. However, setting the reinforcing layer 4 as a non-metallic layer results in lighter weight and lower cost compared to setting it as a metallic layer.

[0045] Preferably, the reinforcing layer 4 is embedded in the plate 100. Of course, the reinforcing layer 4 can also be placed on the surface of the plate 100, while the reinforcing area 3 is embedded in the plate 100, which can make the two sides of the plate 100 flat and make the overall structure more regular.

[0046] Specifically, the plate body 100 is a molded plate 9, and the reinforcing layer 4 is a CFRT layer. The molded plate 9 is a plate made by pressing the reinforcing material (such as glass fiber, carbon fiber or metal fiber) with the resin matrix (such as epoxy resin or polyester resin) under high temperature and high pressure conditions using a mold. The molded plate 9 is lightweight, has good puncture resistance and corrosion resistance, and the one-piece molding reduces the need for fixing, riveting and other processes, making it suitable for mass production and reducing costs.

[0047] CFRT (Continuous Fiber Reinforced Thermoplastic Composites) are layered continuous fiber reinforced thermoplastic composites. They are a new type of thermoplastic composite material with high strength, high rigidity, high toughness, and recyclability, formed through processes such as resin melt impregnation and extrusion. The fibers in CFRT layers are continuous, and the resin impregnation of the individual fiber filaments is more thorough than in conventional thermoplastic composites. Therefore, its mechanical properties, especially tensile, flexural, and impact properties, are far superior to those of conventional thermoplastic composites.

[0048] The mechanical properties of the CFRT layer are superior to those of the molded plate 9, effectively achieving local structural reinforcement of the plate 100 to meet the structural strength requirements of the fuel tank protection plate.

[0049] Of course, in this embodiment, the molding process of the plate 100 is not limited. For example, the plate 100 can also be made into an injection molded part, and the reinforcing layer 4 can be integrally injection molded with the plate 100. The plate 100 is made of a molded plate 9, which has better structural strength and better resistance to impact and corrosion compared to an injection molded part.

[0050] The plate 100 (i.e. the molding plate 9) is preferably a PP+GF (glass fiber reinforced polypropylene) plate. Of course, the molding plate 9 can also be made of PP plate, etc., but using PP+GF plate can further ensure the structural strength of the molding plate 9.

[0051] The reinforcing layer 4 (i.e., the CFRT layer) is preferably a PP+GF (glass fiber reinforced polypropylene) layer, a PC+GF (glass fiber reinforced polycarbonate) layer, a PET+GF (glass fiber reinforced polyethylene terephthalate) layer, a PA+GF (glass fiber reinforced polyamide) layer, etc., which has good puncture resistance and can effectively ensure the structural strength of the reinforcing zone 3.

[0052] Specifically, in the preparation of the plate 100, the PP+GF molding material block is heated and softened, then placed in a molding die to form a molding layer 10. Then, a pre-shaped CFRT layer is partially laid. Next, the PP+GF molding material block is heated and softened, then placed in a molding die to form another molding layer 10. The two molding layers 10 of the body region 2 are molded as follows: Figure 3 The cross-sectional view of the reinforced zone 3 of the single-layer PP+GF board shown is as follows. Figure 4 As shown, a three-layer structure is formed, consisting of a bottom layer, a CFRT layer, and an upper layer arranged sequentially, with the bottom and upper layers being molded layers 10. The manufacturing process is relatively simple.

[0053] Preferably, the thickness of the reinforcing layer 4 is in the range of 1mm-1.5mm. Of course, the thickness of the reinforcing layer 4 can also be set to 0.6mm, 0.8mm, 1.6mm, 1.8mm, etc. Setting the thickness of the reinforcing layer 4 in the range of 1mm-1.5mm, such as 1mm, 1.2mm, 1.5mm, etc., can reduce the overall weight and reduce the cost while ensuring the structural strength and puncture resistance of the reinforcing layer 4, compared to the scheme of setting the thickness of the reinforcing layer 4 to less than 1mm or greater than 1.5mm.

[0054] Preferably, the thickness of the molding layers 10 on both sides of the reinforcing layer 4 is in the range of 1.5mm-2mm. The thickness of the two molding layers 10 can be the same or different, and no specific limitation is made here. Of course, in this embodiment, the thickness of the molding layer 10 can also be 1mm, 1.2mm, 2.2mm, 2.5mm, etc. Setting the thickness of the molding layer 10 in the range of 1.5mm-2mm, such as 1.5mm, 1.8mm, 2mm, etc., compared with the scheme of setting the thickness of the molding layer 10 to less than 1.5mm or greater than 2mm, can ensure the structural strength of the body region 2 while reducing costs.

[0055] Preferably, the thickness of the reinforcing region 3 is in the range of 4mm-6mm. Of course, the thickness of the reinforcing region 3 can also be set to 3mm, 3.5mm, 6.5mm, 7mm, etc. However, setting the thickness of the reinforcing region 3 in the range of 4mm-6mm, such as 4mm, 5mm, 6mm, etc., can reduce the overall thickness and weight and lower the cost while ensuring the structural strength of the reinforcing region 3, compared to setting the thickness of the reinforcing region 3 to be less than 4mm or greater than 7mm.

[0056] Preferably, the thickness of the molding plate 9 is in the range of 3mm-4mm, that is, the thickness of the body region 2 is in the range of 3mm-4mm. Of course, the thickness of the molding plate 9 can also be set to 2mm, 5mm, etc. However, setting the thickness of the molding plate 9 to be in the range of 3mm-4mm, such as 3mm, 3.5mm, 4mm, etc., compared with the scheme of setting the thickness of the molding plate 9 to less than 3mm or greater than 4mm, can reduce the overall thickness and weight of the plate 100 and reduce costs while ensuring the structural strength of the body region 2.

[0057] The puncture resistance of non-metallic fuel tank protection plates in the prior art is 300 N-800 N, while the fuel tank protection plate provided in this application has a puncture resistance of more than 2000 N in the reinforced area 3. Moreover, compared with the metal fuel tank protection plates in the prior art, the weight is significantly reduced. For example, for fuel tank protection plates of the same size, the weight can be reduced by about 300% compared with steel plate solutions, and the cost can be reduced by about 200% compared with aluminum plate solutions.
