Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to a fuel tank that prevents a vehicle from stalling during a sharp turn. Background Technology

[0002] There is a Chinese utility model patent with publication number CN221794384U entitled "A Fuel Tank Storage Structure". This patent document discloses that "a baffle plate 15 is provided at the bottom of the storage cavity 11, which is used to slow down the movement of fuel from the first side 12 to the second side 13. By slowing down the movement of fuel from the first side 12 to the second side 13 by the baffle plate 15, sufficient fuel can be drawn by the fuel suction assembly 2 when the vehicle is driving on a slope or making a sharp turn. Furthermore, a return channel 153 is provided at the bottom of the baffle plate 15, which connects the first side 12, the storage cavity 11, and the second side 13 in sequence. The return channel 153 is used to allow fuel to flow from the first side 12 to the second side 13 or from the second side 13 to the first side 12. By providing the return channel 153, fuel can flow quickly to the first side 12 or the second side 13 through the return channel 153, and the fuel suction assembly 2 can easily draw in the fuel." Based on the accompanying drawings, the return channel is actually a tubular structure. While ensuring the oil-blocking effect of the baffle plate, the diameter of the return channel is small, which limits the oil flow capacity, hinders the timely return of fuel, and can easily cause the vehicle to stall when making sharp turns because it cannot draw in fuel, resulting in poor reliability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a fuel tank that offers fast return and high reliability to prevent vehicle stalling during sharp turns.

[0004] To achieve the above objectives, the technical solution adopted by the fuel tank of this utility model for preventing vehicle stalling during sharp turns is as follows:

[0005] A fuel tank designed to prevent vehicle stalling during sharp turns includes a tank body with a filling port at one end and a fuel inlet at the other. A baffle plate is located inside the tank cavity next to the fuel inlet. The baffle plate includes a door frame panel with support feet on both sides that connect to the inner wall of the tank. A gap for oil passage is left between the bottom surface of the door frame panel and the bottom wall of the tank body. A fuel passage hole is located in the middle of the door frame panel. A baffle plate is located next to the fuel inlet on the side of the door frame panel. The baffle plate has at least two guide posts. A guide hole is provided in the door frame panel through which the guide posts pass, with a clearance fit between the guide hole and the guide post. A limit post is provided at the end of the guide post passing through the guide hole, with the outer diameter of the limit post being larger than the outer diameter of the guide hole.

[0006] Preferably, the height of the oil-filled gap is 4-10mm.

[0007] Preferably, the length of the guide post is 40-100mm.

[0008] Preferably, the bottom of the housing includes a beveled section on the same side as the filling port and an oil suction section on the same side as the oil suction port. The lower end of the beveled section extends toward the oil suction port. The beveled section and the oil suction section are connected by a buffer section. A baffle plate is disposed on the side of the buffer section adjacent to the oil suction section.

[0009] Preferably, a drain hole is provided at the lowest point of the oil suction section, and a sealing plug for sealing the drain hole is provided at the drain hole.

[0010] Preferably, the oil-absorbing section has upwardly protruding bottom ribs on both sides.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. Fuel can be returned through two channels: the fuel gap and the fuel hole. The flow rate is large and the fuel return speed is faster, making it safer and more reliable.

[0013] 2. The door frame panel is supported horizontally inside the box by the support legs, which also helps to improve the strength of the box.

[0014] 3. The oil suction section is located at the lowest point of the box and bears the most weight, so it is necessary to improve its strength by setting bottom ribs. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0024] like Figure 1-7 As shown, a fuel tank for preventing vehicle stalling during sharp turns includes a tank body 1. A filler port 2 is installed at the left end of the tank body 1, and three fuel inlets 3 are installed at the right end. The bottom of the tank body 1 includes a beveled section 11 on the same side as the filler port 2 and a fuel inlet section 12 on the same side as the fuel inlets 3. The lower end of the beveled section 11 extends towards the fuel inlets 3. The beveled section 11 and the fuel inlet section 12 are connected by a buffer section 13, which reduces the impact of fuel, especially during backflow, on the fuel inlets 3. A vent hole 1 is provided at the lowest point of the fuel inlet section 12. 4. A sealing plug 4 is installed at the vent hole to seal it. The vent hole 14 facilitates the cleaning of impurities accumulated in the tank over a long period. A baffle plate 5 is installed on the side of the buffer section 13 adjacent to the oil suction section 12. The baffle plate 5 includes a door frame plate 51 and integrally formed support feet 511 on both sides of the door frame plate. After the support feet 511 are welded to the side walls of the inner cavity of the tank 1, the door frame plate 51 is fixed in the inner cavity of the tank 1. The door frame plate 51 is horizontally supported inside the tank 1 by the support feet 511, which also helps to improve the strength of the tank 1. The bottom of the door frame plate 51... An oil passage gap 6 is provided between the top surface and the bottom wall of the tank body. The height H of the oil passage gap 6 is 6mm. The oil passage gap 6 facilitates the passage of fuel and also helps to remove impurities in the tank body 1 more thoroughly. An oil passage hole 512 is opened in the middle of the door frame plate 51. A baffle 52 is installed on the side of the door frame plate 51 next to the oil suction port 3. The baffle 52 is integrally formed with four guide posts 521. The guide posts 521 are distributed at each corner of the baffle 52. A guide hole 513 is opened in the door frame plate 51 through which the guide posts 521 pass. The guide hole 513 and the guide post 521 are fitted with a clearance fit. One end of the guide post 521 that passes through the guide hole 513 is connected to the limiting post 53 by a flat-head bolt. The outer diameter of the limiting post 53 is larger than the outer diameter of the guide hole 513. The length L of the guide post 521 is 54mm, which allows the baffle 52 to have enough room to move to avoid affecting the fuel backflow. The two sides of the oil suction section 12 are integrally formed with upward-protruding bottom ribs 15. The bottom ribs 15 are located between the drain hole 14 and the baffle 52. Since most of the fuel is concentrated on the side of the oil suction port 3, the bottom ribs 15 are needed to further strengthen the strength of this side of the housing 1.

[0025] The specific working process and principle of a fuel tank to prevent vehicle stalling during sharp turns: When the vehicle makes a sharp turn, fuel moves from the fuel inlet to the filler port. The fuel pushes a baffle plate, which, under the action of a guide post and a guide hole, slides towards the door frame panel, blocking the fuel passage and preventing fuel from moving towards the filler port. This avoids a large loss of fuel from the fuel inlet side, ensuring sufficient fuel supply on that side. When fuel flows back from the filler port to the fuel inlet side, the baffle plate is pushed open by the fuel, and fuel returns simultaneously through the fuel passage and the fuel gap. This fast and efficient return replenishes the fuel lost and consumed on the fuel inlet side, ensuring continuous fuel intake and maintaining vehicle power. This invention, by incorporating a baffle plate with a one-way valve function within the tank, ensures continuous fuel intake during sharp turns, greatly improving safety and reliability.
