Technical Field

[0001] The present invention relates to the technical field related to automobile parts, and in particular to an impact-resistant oil tank for a hybrid automobile. Background Art

[0002] With the rapid development of the automobile industry, the safety, stability and durability of automobile fuel tanks, as an important part of vehicles, have attracted more and more attention. Especially in the field of hybrid vehicles, due to the mixed use of gasoline and electricity, the design requirements for fuel tanks are more stringent. Traditional automobile fuel tanks are often difficult to meet the multiple requirements of modern automobiles for safety, environmental protection and performance in terms of structural design and material use.

[0003] Traditional automobile fuel tanks are mostly made of a single material, such as metal or plastic, which has limitations in terms of impact resistance, high temperature resistance, and corrosion resistance. At the same time, the design of fuel tanks often ignores the optimization of the internal structure, which makes the fuel tanks prone to deformation or even rupture when subjected to external impact, causing fuel leakage and seriously threatening driving safety. Summary of the invention

[0004] In order to fill the gap in the market, the present invention provides an impact-resistant oil tank for a hybrid vehicle.

[0005] The purpose of the present invention is to provide an impact-resistant oil tank for a hybrid vehicle to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an impact-resistant oil-electric hybrid automobile fuel tank, comprising an upper fuel tank body, a lower fuel tank body and a fuel tank nozzle, wherein the upper fuel tank body and the lower fuel tank body are connected by a flange, a mounting plate is fixed at the flange position, and a fuel filling port is arranged on the front of the upper fuel tank body, and a fuel tank nozzle is installed on the fuel filling port, and an oil outlet connected to an oil pipe is arranged below the lower fuel tank body, wherein the upper fuel tank body and the lower fuel tank body comprise an inner wall layer on the inner side, an inner lining layer on the outer side and a hollow interlayer arranged in the middle, and reinforcing ribs are evenly arranged on the outer side of the hollow interlayer, and an outer wall layer is wrapped on the outer side of the reinforcing ribs;

[0007] The fuel tank nozzle includes an oil inlet cap installed on the top at the automobile refueling port position, and a delivery pipe is installed inside the oil inlet cap. The delivery pipe is installed inside a connecting head below, and the connecting head is inserted inside the oil filling port below, and an air inlet and an oil outlet groove are provided at the bottom of the connecting head.

[0008] Furthermore, the hollow interlayer is woven by supporting at the support plate position and inserting 3D carbon fiber woven wires at the gap position of the support plate, and the support plate is made of aluminum plate welded.

[0009] Furthermore, the inner wall layer and the inner lining layer are formed by curing carbon fiber reinforced thermosetting resin and attached to the hollow interlayer, and the outer surface reinforcement ribs of the inner lining layer are pre-embedded with aluminum plates to fit the inner lining layer, and the outer wall layer is wrapped around the outer side of the reinforcement ribs and cured.

[0010] Furthermore, the delivery pipe includes relatively independent exhaust pipe and oil delivery pipe, and the exhaust pipe is connected to the air inlet below the connector, while the oil delivery pipe is connected to the oil outlet groove below the connector.

[0011] Furthermore, a protective tube is connected above the connector, and the upper end of the protective tube is fixed to a limit plate on the outer side of the delivery tube by bolts, while the outer side of the upper end of the delivery tube is screwed to the limit plate.

[0012] Furthermore, a sealing gasket is arranged between the oil inlet cap of the fuel tank nozzle and the fuel filling port of the vehicle. The sealing gasket is made of oil-resistant and high-temperature resistant rubber material, and a sealing ring is also arranged between the connecting head and the fuel filling port.

[0013] Furthermore, an expansion slot is added to the upper tank body and the lower tank body of the gasoline tank, and an expansion tank module can be installed inside the expansion slot. At the same time, the expansion slot is connected to the main tank through a sealing connector.

[0014] Furthermore, filling strips are added to the outside of the upper and lower gasoline tank bodies, and the filling strips are made of metal foil and heat-insulating foam to form a strip structure, and the filling strips are bonded to the inside of the grooves between two adjacent groups of reinforcing ribs.

[0015] Furthermore, the mounting plate is evenly provided with mounting holes, and the mounting plate is fixed to the vehicle frame by bolts.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the overall structure of the fuel tank is significantly strengthened by the hollow interlayer arranged inside the fuel tank and the reinforcing ribs evenly arranged outside the interlayer. This design enables the fuel tank to more effectively disperse and resist the impact force when subjected to external impact, thereby improving the impact resistance of the fuel tank. The wrapping of the outer wall layer further enhances the overall strength of the fuel tank, making it more stable and reliable in a complex use environment. The design of the fuel tank nozzle, especially the oil inlet cap, delivery pipe, connector and the air inlet and oil outlet groove inside the fuel tank, ensures the smooth supply of fuel, while also improving the efficiency and safety of fuel filling. The provision of the protective pipe further protects the delivery pipe and reduces the risk of damage to the delivery pipe under external impact. The sealing ring provided between the oil filling port and the connector effectively prevents fuel leakage and ensures the sealing performance of the fuel tank. This not only improves the utilization rate of the fuel, but also reduces the potential safety hazards caused by leakage.

[0017] The expansion slots added to the upper and lower bodies of the gasoline tank provide users with the possibility of installing extended fuel tank modules as needed. This design allows the capacity of the fuel tank to be flexibly adjusted according to actual needs, meeting the diverse needs of different users. By adding filling strips to the outside of the fuel tank, the thermal insulation performance of the fuel tank has been significantly improved. This design helps to reduce the impact of the external environment on the fuel temperature in the tank, thereby improving the stability and efficiency of the fuel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Specific implementation method 1: Please refer to Figure 1-6The present invention provides a technical solution: an impact-resistant oil-electric hybrid vehicle fuel tank, comprising an upper fuel tank body 1, a lower fuel tank body 2 and a fuel tank nozzle 3, wherein the upper fuel tank body 1 and the lower fuel tank body 2 are connected by a flange, a mounting plate 4 is fixed at the flange position, a fuel filling port 11 is arranged on the front of the upper fuel tank body 1, and the fuel tank nozzle 3 is installed on the fuel filling port 11, and an oil outlet 21 connected to an oil pipe is arranged below the lower fuel tank body 2, the upper fuel tank body 1 and the lower fuel tank body 2 comprise an inner wall layer 5 on the inner side, an outer lining layer 7 and a hollow interlayer 6 arranged in the middle, and reinforcing ribs 8 are evenly arranged on the outer side of the hollow interlayer 6, and an outer wall layer 9 is wrapped around the outer side of the reinforcing ribs 8:

[0027] The fuel tank nozzle 3 includes an oil inlet cap 31 installed at the top of the automobile fuel filling port, and a delivery pipe 39 is installed inside the oil inlet cap 31. The delivery pipe 39 is installed inside the connecting head 310 below, and the connecting head 310 is inserted inside the oil filling port 11 below, and the bottom of the connecting head 310 is provided with an air inlet 36 and an oil outlet groove 37.

[0028] The user can open the fuel inlet cap 31, insert the fuel tank nozzle 3 into the fuel filling port of the car, and then fill the fuel. The fuel enters the fuel filling port 11 through the delivery pipe 39 and the connector 310, and is stored in the upper tank body 1 and the lower tank body 2 of the gasoline tank. When the fuel is needed, the fuel is drawn out from the oil outlet 21 through the connecting oil pipe and supplied to the engine and other oil-consuming parts.

[0029] The multi-layer structural design improves the overall strength of the fuel tank. Reinforcing ribs are set on the outside of the hollow interlayer to further enhance the impact resistance of the fuel tank. A delivery pipe and a connector are set inside the fuel inlet cap to facilitate the filling and delivery of fuel. An air inlet and an oil outlet groove are set inside the connector to ensure smooth delivery and stable use of the fuel. It is suitable for hybrid vehicles and meets the high requirements for fuel tank safety and stability.

[0030] The hollow interlayer 6 is woven by supporting at the support plate 62 and inserting 3D carbon fiber woven wires 61 in the gaps of the support plate 62, and the support plate 62 is made of aluminum plates welded together.

[0031] The combination of 3D carbon fiber yarn 61 and aluminum plate welding makes the hollow sandwich have extremely high structural strength, which can withstand various complex external forces and pressures. The supporting effect of the support plate 62 and the weaving method of the 3D carbon fiber yarn 61 make the hollow sandwich structure more stable and not easy to deform or damage. The closed structure of the hollow sandwich can effectively isolate the influence of the external environment on the internal temperature of the fuel tank, thereby improving the stability and utilization efficiency of the fuel.

[0032] The inner wall layer 5 and the inner lining layer 7 are formed by curing carbon fiber reinforced thermosetting resin and attached to the hollow interlayer 6. The outer surface reinforcement ribs 8 of the inner lining layer 7 are pre-embedded with aluminum plates to fit the inner lining layer 7, and the outer wall layer 9 is wrapped around the outer side of the reinforcement ribs 8 and cured.

[0033] During the curing process, the carbon fiber and the thermosetting resin are mixed and laid through a specific process, and cured under heating and pressurization conditions. The cured material not only retains the high strength characteristics of the carbon fiber, but also has the excellent properties of the thermosetting resin, such as high temperature resistance and chemical corrosion resistance. After curing, the inner wall layer 5 and the inner lining layer 7 are attached to the hollow interlayer 6 through a specific process. This attachment method ensures the close combination of the layers and avoids stratification or peeling during use.

[0034] The outer surface of the inner lining layer 7 is reinforced with reinforcing ribs 8, and the reinforcing ribs 8 are bonded to the inner lining layer 7 by pre-embedded aluminum plates. This method can ensure a firm connection between the reinforcing ribs and the inner lining layer. At the same time, the pre-embedded aluminum plates can also improve the thermal conductivity of the reinforcing ribs, which helps to evenly distribute the temperature inside the fuel tank. On the outside of the reinforcing ribs 8, an outer wall layer 9 is wrapped and cured. The function of the outer wall layer 9 is to protect the internal structure of the fuel tank and prevent erosion and damage from the external environment. At the same time, it can also improve the overall strength and stability of the fuel tank.

[0035] Furthermore, the aluminum plate may be formed of a hollow aluminum plate structure.

[0036] The delivery pipe 39 includes a relatively independent exhaust pipe 35 and an oil delivery pipe 38 , wherein the exhaust pipe 35 is communicated with an air inlet 36 below the connector 310 , and the oil delivery pipe 38 is communicated with an oil outlet groove 37 below the connector 310 .

[0037] A protection tube 34 is connected to the top of the connector 310 , and the upper end of the protection tube 34 is fixed to the limit plate 32 on the outer side of the delivery tube 39 by bolts. Meanwhile, the outer side of the upper end of the delivery tube 39 is screwed to the limit plate 32 .

[0038] The exhaust pipe 35 is connected to the air inlet 36 below the connector 310; during the fuel filling process, the gas inside the fuel tank will be discharged through the air inlet 36 and the exhaust pipe 35 to ensure that the fuel can smoothly enter the fuel tank; at the same time, the exhaust pipe 35 also plays a role in balancing the air pressure inside and outside the fuel tank to prevent the fuel filling from being affected by the air pressure change;

[0039] The oil delivery pipe 38 is connected to the oil outlet groove 37 below the connector 310; the fuel flows from the filling device into the fuel tank through the oil delivery pipe 38; in order to ensure the smooth flow of the fuel, the oil delivery pipe 38 usually has a sufficient diameter and a smooth channel design;

[0040] The connector 310 is a connecting component between the fuel tank nozzle 3 and the fuel tank filling port 11; it is responsible for connecting the delivery pipe 39 with the inside of the fuel tank to ensure that the fuel can accurately flow into the fuel tank; the connector 310 is provided with an air inlet 36 and an oil outlet groove 37, which are connected to the exhaust pipe 35 and the fuel delivery pipe 38 respectively;

[0041] The protection tube 34 is located above the connector 310 and is fixed to the limit plate 32 on the outside of the delivery tube 39 by bolts; the main function of the protection tube 34 is to protect the delivery tube 39 from external impact and damage; at the same time, the protection tube 34 can also increase the overall stability of the tank nozzle 3 to ensure that it will not shake or fall off during the filling process;

[0042] The main function of the limit plate 32 is to fix and limit the position of the delivery pipe 39 to prevent it from being offset or twisted during the filling process; at the same time, the limit plate 32 can also increase the structural strength of the tank nozzle 3 and improve its overall durability.

[0043] A sealing gasket is arranged between the oil inlet cap 31 of the oil tank nozzle 3 and the fuel filling port of the vehicle. The sealing gasket is made of oil-resistant and high-temperature resistant rubber material. A sealing ring 311 is also arranged between the connector 310 and the fuel filling port 11.

[0044] An expansion slot is added to the upper tank body 1 and the lower tank body 2 of the gasoline tank. An expansion tank module can be installed inside the expansion slot. At the same time, the expansion slot is connected to the main tank through a sealing connector.

[0045] The expansion slot is connected to the main fuel tank through sealing connectors to ensure the sealing and safety of the fuel tank; these sealing connectors are made of high-strength, corrosion-resistant materials and have good sealing performance and durability; when installing the extended fuel tank module, the sealing connectors are tightly pressed into the interface between the expansion slot and the extended fuel tank module to form a firm and reliable connection; the installation and removal process of the extended fuel tank module is simple and quick; users only need to follow the steps in the instruction manual to easily install the extended fuel tank module into the expansion slot or remove it from the expansion slot, so that the capacity of the fuel tank can be flexibly adjusted as needed, providing users with greater convenience and choice.

[0046] Filling strips are added to the outside of the upper tank body 1 and the lower tank body 2 of the gasoline tank. The filling strips are made of metal foil and heat-insulating foam to form a strip structure. The filling strips are bonded to the inside of the grooves between two adjacent groups of reinforcing ribs 8.

[0047] The mounting plate 4 is evenly provided with mounting holes, and the mounting plate 4 is fixed to the vehicle frame by bolts.

[0048] Carbon fiber reinforced thermosetting resin is used for mold forming to obtain the inner wall layer 5 and the inner lining layer 7 of the upper and lower boxes of the fuel tank, which are supported at the support plate 62, and 3D carbon fiber woven wires are inserted into the gaps of the support plate 62 to weave into a hollow sandwich to ensure that the sandwich is evenly distributed inside the entire fuel tank. On the outer surface of the inner lining layer 7, reinforcing ribs are provided by pre-embedding aluminum plates to enhance the impact resistance of the fuel tank. The outer wall layer 9 material is evenly wrapped around the outer sides of the inner wall layer 5, the inner lining layer 7 and the hollow sandwich layer 6, and the overall strength and density of the fuel tank are ensured by curing treatment. Sealing: Assemble the oil inlet cap 31, delivery pipe 39, connector 310 and other components according to the design requirements to ensure the normal function of the fuel tank nozzle 5, and set a sealing gasket between the oil inlet cap and the car refueling port to prevent fuel leakage; add expansion slots to the upper box body 1 and the lower box body of the gasoline tank, and add filling strips made of metal foil and thermal insulation foam to the outside of the fuel tank to improve the thermal insulation performance of the fuel tank: connect the upper box body and the lower box body through a flange, and fix the mounting plate 4 at the flange position. The mounting plate 4 is fixed to the frame by bolts to ensure the stability and safety of the fuel tank.

[0049] A hollow interlayer 6 is designed inside the fuel tank, which is woven from a support plate 62 and a 3D carbon fiber yarn 61. The support plate 62 plays a structural support role in the interlayer, while the 3D carbon fiber yarn enhances the overall strength and stability of the interlayer. This design enables the fuel tank to effectively disperse and resist impact force when subjected to external impact, thereby improving the impact resistance of the fuel tank and reducing the mass of the fuel tank without ensuring fuel leakage.
