DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0023] like Figure 1-4 As shown, a fuel pump assembly with a new type of flangeless connection method includes:

[0024] The base 4 is provided with pillars 42 in a circular array, and a circular hole is opened at the axis of the pillars 42;

[0025] The upper cover 2 has a bottom with a clamping rod 24 that engages with the circular hole;

[0026] The pump core 3 is arranged between the base 4 and the upper cover 2. The pump core 3 has an oil suction end 30 and an oil outlet end 31. The oil suction end 30 is clamped with a filter screen 7 that matches the base 4, and the oil outlet end 31 is clamped with an oil pipe 5, and the oil pipe 5 runs through the upper cover 2.

[0027] Specifically, the base 4 is provided with pillars 42 in a circular array, at least four pillars 42 are provided, and the number of the clamping rods 24 corresponds to that of the pillars 42. A circular hole is opened at the axis of the pillar 42, and a clamping rod 24 engaged with the circular hole is provided at the bottom of the upper cover 2. The pump core 3 is provided between the base 4 and the upper cover 2, and the pump core 3 has an oil suction end 30 and an oil outlet end 31. A filter screen 7 matching the base 4 is clamped on the oil suction end 30, and an oil pipe 5 is clamped on the oil outlet end 31. The oil pipe 5 passes through the upper cover 2, and a pump core 3 is provided on the base 4. There is a column hole, and the pump core 3 is pre-inserted into the column hole, and the clamping rod 24 of the upper cover 2 is inserted into the circular hole of the pillar 42 to complete the support of the pump core 3. The upper cover 2 is matched with the fuel tank, so that the filter screen 7 at the oil suction end 30 of the pump core 3 is placed at the bottom of the fuel tank. When the pump core 3 is running, the oil in the fuel tank will be sucked through the filter screen 7 in advance to filter impurities in the oil. Then, after a certain pressure is applied to the oil, it is continuously output from the oil pipe 5 to the engine. The device cannot be installed on the fuel tank by flange, which improves the installation efficiency and facilitates the subsequent removal and maintenance of the fuel pump.

[0028] As an embodiment further provided by the present invention, an oil supply connector 311, a pipe connector 312 and a socket 313 are provided on the oil outlet end 31 of the pump core 3. The oil supply connector 311 is engaged with the oil pipe 5, and a wiring harness 1 is provided on the socket 313. A bellows 6 is provided on the pipe connector 312, and an oil return plastic part 8 is provided at one end of the bellows 6. The oil supply connector 311 is connected to the oil pipe 5, so that the pump core 3 supplies oil to the engine through the oil pipe 5 when the oil is extracted. The pipe connector 312 is provided with a bellows 6 connected to the oil return plastic part 8. The unburned oil flows along the bellows 6 to the oil return plastic part 8, and flows back to the fuel tank from the oil return plastic part 8, which can relieve the pressure of gasoline and reduce fuel consumption. The socket 313 is connected to the wiring harness 1, and the wiring harness 1 is externally connected to a control device to control the switch of the pump core 3 through an electrical signal.

[0029] As an embodiment further provided by the present invention, the oil return plastic part 8 is symmetrically provided with a card block 81 that cooperates with the base 4, and a card slot 41 is opened on the base 4, and the card block 81 on the oil return plastic part 8 is inserted into the card slot 41, so as to support the oil return plastic part 8 so that the oil outlet of the plastic oil return part faces the bottom of the oil tank.

[0030] As an embodiment further provided by the present invention, a sealing ring is provided at the connection between the oil pipe 5 and the oil supply joint 311, and the sealing ring improves the sealing between the oil pipe 5 and the oil supply structure to prevent oil leakage.

[0031] As an embodiment further provided by the present invention, an inclined portion 25 is provided on the clamping rod 24, and the inclined portion 25 cooperates with the pillar 42. A groove is provided at the center of the inclined portion 25 to facilitate the clamping rod 24 to be inserted into the pillar 42. The inclined portion 25 makes the connection between the upper cover 2 and the base 4 more stable.

[0032] As an embodiment further provided by the present invention, reinforcing ribs 421 are symmetrically arranged on the pillar 42 , and the reinforcing ribs 421 improve the overall stability of the pillar 42 .

[0033] As an embodiment further provided by the present invention, an arc-shaped cover 23 is provided on the upper cover 2, and a wire hole 22 matching the oil pipe 5 is opened on the arc-shaped cover 23. There is a accommodating cavity inside the arc-shaped cover 23, and the oil supply connector 311, the pipe connector 312 and the socket 313 are all arranged in the accommodating cavity. After the oil supply connector 311, the pipe connector 312 and the socket 313 are respectively clamped with the oil pipe 5, the corrugated tube 6 and the wiring harness 1, they are led out through the wire hole 22.

[0034] As an embodiment further provided by the present invention, the upper cover 2 is symmetrically provided with a fuel tank buckle plate 21, which improves the supporting effect of the upper cover 2 and the fuel tank. At the same time, the design of the fuel tank buckle plate 21 is also convenient for separating the fuel tank as a whole.

[0035] Working principle: First, fix the upper cover 2 to the fuel tank. The fuel tank buckle plate 21 on the upper cover 2 improves the overall stability, and the pump core 3 is pre-inserted into the column hole of the base 4, and the clamping rod 24 on the upper cover 2 is engaged with the support column 42 of the base 4 to fix the fuel pump. The wiring harness 1 is connected to an external control device, and the operation of the pump core 3 is controlled by the wire number, so that the oil flows into the pump core 3 through the filter screen 7, and is applied under a certain pressure to be continuously output along the oil pipe 5 to the engine for fuel supply. When the fuel pump supplies fuel to the engine, the return oil plastic part 8 returns the remaining fuel to the fuel tank through the return oil pipe 5, which can relieve the pressure of gasoline and reduce fuel consumption.

[0036] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.
