Description

Technical Field

[0001] The utility model relates to the technical field of fuel tanks, in particular to a fuel tank which can prevent an oil pipe from being sucked empty on a steep slope. Background Art

[0002] When designing the automobile fuel supply system, the fuel tank is usually designed to be flatter and longer in shape due to the limitations of the layout environment. In order to ensure that the vehicle can smoothly absorb the fuel in the fuel tank when going uphill, the oil suction pipe is usually arranged at the rear of the fuel tank (with the vehicle's forward direction as the front) to ensure that the fuel can be sucked during the uphill process. However, when the car is in the downhill process, if the amount of fuel in the fuel tank is small and the slope is large, the oil suction pipe may be sucked empty. After the empty state continues for a period of time, it will cause the engine to stall, seriously affecting driving safety. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art and provide a fuel tank which can prevent the fuel pipe from being sucked empty on a steep slope, thereby preventing the fuel from flowing from a relatively high position to the lowest position, thereby effectively preventing the occurrence of fuel sucking empty.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A fuel tank for preventing the oil pipe from being sucked empty on a steep slope, comprising a fuel tank body, the fuel tank body being provided with an oil suction circuit, an oil return circuit and a breather box cover, two partitions being provided on the bottom surface of the fuel tank body, the height of the partitions being less than the height of the inner cavity of the fuel tank body, the two partitions and the inner wall of the fuel tank body forming an oil storage space with an open top, the bottom end of the oil suction circuit being located between the two partitions, a V-shaped slide being provided horizontally between the two partitions, one end of the V-shaped slide being fixed to one of the partitions, and the other end being fixed to the other partition, a valve ball being provided on the V-shaped slide, and a conical hole being provided on the partition that is adapted to the valve ball.

[0006] Preferably, the height of the partition is less than half of the height of the inner cavity of the fuel tank body, and greater than one quarter of the height of the inner cavity of the fuel tank body.

[0007] Preferably, the height of the V-shaped slideway is not less than one fifth of the height of the inner cavity of the tank body.

[0008] Preferably, a limit plate is provided on the top of the V-shaped slideway for preventing the valve ball from falling off the V-shaped slideway.

[0009] Preferably, both ends of the top of the V-shaped slideway are provided with V-shaped stoppers with openings facing downwards.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model cooperates with the partition, the V-shaped slide, the valve ball and the tapered hole. When the fuel tank is tilted, the valve ball rolls toward the lower end on the V-shaped slide and rolls to the tapered hole of the partition at the corresponding end, blocking the tapered hole on the partition to prevent the fuel from flowing further downward, thereby preventing the fuel from flowing from a relatively high position to the lowest position, thereby effectively preventing the occurrence of fuel cavitation.

[0017] Example: As attached Figure 1-3 As shown, the utility model is an oil tank for preventing the oil pipe from being sucked empty on a steep slope, comprising an oil tank body 1, on which an oil suction path 2, an oil return path 3 and a breather box cover 4 are provided.

[0018] The top surface of the oil tank body 1 is provided with an oil filling port adapted to the respirator box cover 4, an oil suction hole adapted to the oil suction path 2, and an oil return hole adapted to the oil return path 3, and screw holes are evenly distributed around the oil suction hole and the oil return hole.

[0019] The oil suction circuit 2 is composed of an oil suction pipe and an oil pipe A. A flange A is arranged at the upper end of the oil suction pipe, and circular holes are evenly distributed around the flange A.

[0020] The oil return circuit 3 is composed of an oil return pipe and an oil pipe B. A flange B is provided at the upper end of the oil return pipe, and circular holes are evenly distributed around the flange B.

[0021] The respirator tank cover 4 is composed of a fuel tank cover, a filter cup and a connecting strip. The filter cup passes through the fuel filling port and is installed in the fuel tank body 1, and the upper edge of the filter cup cooperates with the top surface of the fuel filling port. The fuel tank cover and the thread on the outer circle of the fuel filling port form a spiral fit. The upper end of the connecting strip is connected to the fuel tank cover by screws, and the lower end is installed in the fuel filling port.
