Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a fuel tank assembly, an engine and a vehicle. Background Art

[0002] With the development of science and technology and the improvement of users' living standards, vehicles have become an indispensable means of transportation for people. A fuel tank is provided in the vehicle, which can provide sufficient fuel reserves for the vehicle's engine to ensure that the vehicle can travel a certain mileage.

[0003] When a car adopts a longitudinal fuel tank layout, the fuel pump is often installed at the rear of the fuel tank. When the vehicle goes uphill, the engine output power is large and the fuel consumption is high. When going uphill, the gasoline will flow to the rear of the fuel tank. The fuel pump can always suck the oil to ensure the normal driving of the vehicle. However, when the vehicle goes downhill, the gasoline will flow to the front of the fuel tank. Since the fuel consumption of the vehicle is low when going downhill, the oil in the fuel pump storage barrel can support the vehicle to travel a certain distance. Therefore, when designing the fuel tank, if the length of the fuel tank is small, the remote oil suction function will not be increased outward. If the fuel tank is long and a remote oil suction pipe is added, if the end of the remote oil suction pipe is not fixed, the pipe will hit the fuel tank when the vehicle is bumpy, causing abnormal noise, thus affecting the driving experience of the vehicle.

[0004] In the relevant technology, the common way to ensure the remote oil suction effect is to open another hole in the fuel tank and install an auxiliary pump to fix the end of the remote oil suction pipe. The auxiliary pump needs to be installed with a flange and an auxiliary pump sealing ring. This will increase the cost of the vehicle, and the increase in the opening of the fuel tank will lead to increased evaporation emissions of the oil, which is not conducive to environmental protection. There is a risk that the vehicle will not meet the inspection regulations and cannot be put on the market. Utility Model Content

[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 5 The fuel tank assembly 100 according to the embodiment of the present invention is described. The fuel tank assembly 100 can be applied to a vehicle.

[0034] Combination Figure 1-Figure 5 As shown, the oil tank assembly 100 according to the utility model can mainly include: an oil tank body 10, an oil pump 20 and a connecting pipe 30. Among them, the oil tank body 10 is provided with an integrally formed clamping portion 101, which can not only ensure the stable and reliable connection between the clamping portion 101 and the oil tank body 10, but also reduce the number of parts and assembly processes, thereby simplifying the production process and reducing production costs.

[0035] The oil pump 20 is arranged on the fuel tank body 10, so that the fuel can be sucked out of the fuel tank body 10 and pressurized to deliver the fuel to the fuel system of the engine to ensure that the engine can obtain an appropriate amount of fuel with a certain pressure, thereby meeting the fuel demand of the engine and ensuring the normal operation of the engine.

[0036] One end of the connecting pipe 30 is connected to the oil pump 20, and the other end is connected to the fuel tank body 10, and the connecting pipe 30 is fixedly connected to the clamping portion 101. Specifically, one end of the connecting pipe 30 is connected to the oil pump 20, and the other end is connected to the fuel tank body 10, so that the fuel in the fuel tank body 10 can be smoothly delivered to the oil pump 20, and then the fuel is delivered to the engine by the oil pump 20, so that no matter how the posture of the vehicle and the fuel level in the fuel tank body 10 change, the oil pump 20 can be guaranteed to continuously and stably obtain fuel, and the interruption or fluctuation of fuel supply can be avoided, thereby ensuring the reliable operation of the engine.

[0037] Furthermore, the connecting pipe 30 is fixedly connected with the clamping part 101, which not only makes the connection between the connecting pipe 30 and the fuel tank body 10 simple, direct, stable and reliable, but also prevents the connecting pipe 30 from shaking or moving, thereby ensuring the oil suction path of the oil pump 20, improving the oil suction efficiency and effect of the oil pump 20, and preventing the fuel tank assembly 100 from making abnormal noises that affect the passenger experience. In addition, the clamping and fixing method not only saves space, but also facilitates the subsequent maintenance and replacement of the connecting pipe 30.

[0038] Furthermore, the pipe mouth or other position of the connecting pipe 30 can be equipped with a filtering device 301 to prevent solid particles, dirt, rust and other impurities in the fuel tank body 10 from entering the oil pump 20 and the fuel system. This can not only reduce the wear of the connecting pipe 30, the oil pump 20 and the fuel system, prevent the fuel delivery system from being blocked, thereby improving the stability and reliability of the fuel system, but also ensure that the fuel supplied to the engine is purer, help improve the combustion efficiency of the fuel, reduce carbon deposits and pollutant emissions, and is beneficial to environmental protection.

[0039] Therefore, by providing an integrally formed clamping portion 101 on the fuel tank body 10 and clamping and fixing the connecting pipe 30 to the clamping portion 101, not only can the oil be transported from the bottom of the fuel tank body 10 or a position away from the oil pump 20 to the inlet of the oil pump 20, thereby improving the oil suction efficiency and oil suction effect of the fuel tank assembly 100, but also the connecting pipe 30 can be prevented from shaking or moving to produce abnormal noise, thereby affecting the driving experience of the vehicle. Furthermore, the normal operation of the entire fuel supply system or related liquid delivery system during the driving of the vehicle can be guaranteed, the reliability of the vehicle can be improved, and the manufacturing cost of the vehicle can be reduced.

[0040] Combination Figure 2 and Figure 3As shown, the clamping portion 101 is a clamping slot, and the connecting pipe 30 is clamped and fixed with the clamping slot. Specifically, by setting the clamping portion 101 as a clamping slot, and clamping and fixing the connecting pipe 30 with the clamping slot, not only can the connection between the connecting pipe 30 and the oil tank body 10 be simple and direct, but also the connection between the connecting pipe 30 and the oil tank body 10 can be stable and reliable.

[0041] Furthermore, the use of a snap-on fixed connection method can reduce the need for additional fasteners such as bolts and rivets, reduce the number of parts and simplify the structure, and does not require the use of complex tools and cumbersome operations. It can quickly complete installation, fixation and disassembly, which not only simplifies the assembly process and improves work efficiency, but also helps with subsequent maintenance and replacement needs.

[0042] Combination Figure 2 and Figure 3 As shown, the inner wall of the card slot is provided with a limiting protrusion 102 in the circumferential direction, and the limiting protrusion 102 is limitedly matched with the connecting pipe 30. Specifically, by providing the limiting protrusion 102 in the circumferential direction of the inner wall of the card slot, and making the limiting protrusion 102 and the connecting pipe 30 limitedly matched, not only can the card slot be more firmly fixed to the connecting pipe 30, but also the connecting pipe 30 can be prevented from slipping in the card slot, thereby avoiding affecting the normal operation of the fuel system, but also the structural strength of the card slot itself can be improved, and the service life of the card slot can be extended, and further, the stability and safety of the fuel tank assembly 100 can be improved.

[0043] Combination Figure 2 and Figure 3 As shown, an arc-shaped guide surface is provided on the surface of the limiting protrusion 102. Specifically, by providing the surface of the limiting protrusion 102 as an arc-shaped guide surface, not only can the jamming and resistance when the clamping slot and the connecting pipe 30 are engaged be reduced, the assembly and disassembly processes of the connecting pipe 30 can be made smoother, but also the wear between the clamping slot and the connecting pipe 30 can be reduced, and the reliability of the structure can be improved.

[0044] In some examples of the present invention, the limiting protrusion 102 can be applied to connecting pipes 30 of different sizes. The capacity of the fuel tank assembly 100 of different models of vehicles and the fuel requirements of the engines are different, and the sizes of the connecting pipe 30 are also different. This configuration can improve the versatility and flexibility of the card slot, save the development cost of the vehicle card slot, and facilitate the modification of the vehicle.

[0045] Combination Figure 1 , Figure 2 and Figure 3As shown, a protrusion 103 is provided on the fuel tank body 10, and the protrusion 103 is provided protrudingly relative to the surface of the fuel tank body 10, and the protrusion 103 is at least partially recessed to form a slot. Specifically, by directly providing the protrusion 103 on the fuel tank body 10, not only can a setting point be provided for the slot, but also additional connectors and components can be reduced, so that the overall structure of the fuel tank body 10 can be made more compact, and the space utilization rate of the fuel tank body 10 can be improved, thereby increasing the storage capacity of the fuel. Further, by providing the protrusion 103 protrudingly relative to the surface of the fuel tank body 10, and the protrusion 103 is at least partially recessed to form a slot, not only can the assembly complexity and cost of the slot be reduced, but also the stability of the connection between the slot and the fuel tank body 10 can be ensured, so that the slot can be prevented from falling off or loosening during the driving of the vehicle, so that the normal operation of the vehicle fuel system can be ensured, and the reliability and stability of the vehicle fuel system can be improved.

[0046] Combination Figure 1 , Figure 2 and Figure 3 As shown, there are multiple slots, which are arranged at intervals on the fuel tank body 10, and the connecting pipe 30 is fixedly connected with the multiple slots. Specifically, by arranging multiple slots at intervals on the fuel tank body 10, and making the connecting pipe 30 fixedly connected with the multiple slots, not only can the connecting pipe 30 be fixed more firmly at a specific position, improving the stability of the connecting pipe 30, but also the force on the connecting pipe 30 can be more uniform, avoiding the connection pipe 30 from partially sagging and directly contacting the bottom of the fuel tank body 10 to cause wear, thereby affecting the service life of the connecting pipe 30 and the fuel tank body 10. In addition, it is also convenient to adjust the position and angle of the connecting pipe 30 to meet different structural requirements, and further, the overall stability and reliability of the fuel tank assembly 100 can be improved.

[0047] Combination Figure 1 , Figure 4 and Figure 5 As shown, the fuel tank assembly 100 further includes a pipe clamp 40, which is welded to the fuel tank body 10 and fixedly connected to the connecting pipe 30. Specifically, by welding the pipe clamp 40 to the fuel tank body 10 and fixingly connected to the connecting pipe 30, not only can the connection between the pipe clamp 40 and the fuel tank body 10 be simple, direct, stable and reliable, but also the connecting pipe 30 can be prevented from displacement, bending or sagging due to vibration, external force or its own weight, and the strength of the structure of the pipe clamp 40 can be ensured, so that it is not easy to break or damage. In addition, welding does not require additional connectors or fasteners, which can simplify the processing process and reduce the manufacturing cost.

[0048] In some examples of the present invention, there may be multiple pipe clamps 40 , and the multiple pipe clamps 40 are arranged at intervals on the fuel tank body 10 , and the connecting pipe 30 is connected and fixed to the multiple pipe clamps 40 .

[0049] Combination Figure 1 , Figure 3 and Figure 5 As shown, the fuel tank assembly 100 further includes a pipe clamp 40, and the fuel tank body 10 is provided with an integrally formed clamping protrusion, the clamping protrusion is clamped and matched with the pipe clamp 40, and the pipe clamp 40 is connected and fixed to the connecting pipe 30. Specifically, by providing an integrally formed clamping protrusion on the fuel tank body 10, a mounting point is provided for the pipe clamp 40, and the clamping protrusion is clamped and matched with the pipe clamp 40, so that not only the connection between the pipe clamp 40 and the clamping protrusion is simple, direct, stable and reliable, but also the disassembly of the pipe clamp 40 is convenient, and the subsequent maintenance and replacement of the pipe clamp 40 is convenient.

[0050] Furthermore, the pipe clamp 40 is connected and fixed to the connecting pipe 30, which can provide a stable clamping force for the connecting pipe 30 and ensure that the connecting pipe 30 is not easily displaced or loosened when the vehicle is bumpy or subjected to external forces, thereby ensuring that the connecting pipe 30 can function normally.

[0051] Furthermore, the clamping fixation between the clamping protrusion and the tube clamp 40 and the connection fixation between the tube clamp 40 and the connecting pipe 30 cooperate with each other. Such a cooperative connection method can not only ensure the stability of the connection between the components, but also absorb and reduce the vibration generated during the operation of the connecting pipe 30, thereby reducing the vibration transmission and the noise generated thereby, and can improve the stability and reliability of the tank assembly 100.

[0052] In some examples of the present invention, there may also be multiple clamping protrusions and multiple pipe clamps 40 , and the multiple clamping protrusions and multiple pipe clamps 40 correspond to each other one by one and are arranged at intervals on the tank body 10 , and the connecting pipe 30 is connected and fixed to the multiple pipe clamps 40 .

[0053] The engine according to the utility model can mainly include: the above-mentioned fuel tank assembly 100. Specifically, since the structure of the fuel tank assembly 100 is more stable and reliable and has good working performance, the application of the fuel tank assembly 100 to the engine can not only provide sufficient fuel reserves for the engine to meet the fuel demand of the engine, but also improve the stability of the engine and ensure the normal operation of the engine.

[0054] The vehicle according to the utility model can mainly include: the above-mentioned engine. Specifically, since the structure of the engine including the fuel tank assembly 100 is more stable and has good working performance, applying the engine including the fuel tank assembly 100 to the vehicle can not only improve the stability of the vehicle structure, but also reduce the noise of the vehicle and the manufacturing cost of the vehicle.
