Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle fuel pump equipment, in particular to a motorcycle fuel pump assembly integrated with an electronic control unit. Background Technique

[0002] A fuel pump is a professional term in the motorcycle parts industry. It is one of the basic components of a fuel injection system and is located inside the vehicle fuel tank. The fuel pump works when starting and the engine is running. If the engine stops while the ignition switch is still in the ON position, the HFM-SFI control module shuts off the power supply of the fuel pump to avoid accidental ignition. The function of the fuel pump is to suck fuel out of the fuel tank, pressurize it and then transport it to the fuel supply pipeline, and cooperate with the fuel pressure regulator to establish a certain fuel pressure.

[0003] The application number is CN202022644681.9, which discloses a motorcycle fuel pump assembly, including a base. A regulating valve is arranged above the base, and an oil pump is also arranged on the right side of the base. The right side of the oil pump is connected with a filtering mechanism; by adopting the above technical solution, it operates normally after being powered on. The oil pump sucks oil, and the fuel enters the oil pump through the filter screen. The fuel flows out of the oil pump and enters the base assembly. In the case of pressure overload, the regulating valve is pushed open to return part of the excess fuel. The mainstream fuel is output to the fuel nozzle and continuously transported to the fuel supply pipe. Under normal circumstances, there will be a certain amount of fuel stored in the cavity of the bracket to ensure that the vehicle does not stall when going downhill and turning when the vehicle fuel is less.

[0004] The following defects exist in the motorcycle fuel pump assembly disclosed in the above document: when this fuel pump is in use, the fuel needs to be transmitted back and forth in the pump through the fuel nozzle. This structure does not have a sealing component between the fuel nozzle and the fuel pump. When the pressure in the pump is too high, the fuel is very likely to leak from the connection between the pump pipe and the fuel nozzle, wasting the fuel cost.

[0005] It can be seen from this that the existing motorcycle fuel pump assembly does not have the function of stable fuel transmission without leakage, and it is necessary to improve the existing deficiencies to provide a function of stable fuel transmission without leakage. Content of the Utility Model

[0006] The purpose of the utility model is to provide a motorcycle fuel pump assembly integrated with an electronic control unit to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a motorcycle fuel pump assembly with an integrated electronic control unit, comprising a fuel assembly and a sealing assembly. The sealing assembly is mounted inside the fuel assembly. The fuel assembly includes a housing, a return pipe is provided at the bottom of the housing, a gasket is sleeved on the outer wall of the return pipe, a nozzle is threadedly connected to the outer wall of the return pipe, a mounting block is sleeved inside the nozzle, a threaded groove is formed on the outer wall of the mounting block, and the mounting block is threadedly connected to the inner wall of the return pipe. The purpose of this arrangement is that during use of the fuel pump, the interface is used to connect to the drive assembly, the oil outlet pipe is used to connect to the pipe for transporting fuel, the fuel assembly is fixed to the vehicle via a flange mounting connector, the fuel assembly performs fuel delivery when the armature and brushes cooperate, the nozzle is installed in the return pipe, and fuel is transferred to the housing through the nozzle for operation. The gasket is provided to fill the gap between the nozzle and the return pipe, thereby enhancing the sealing of the fuel pump. The mounting block is designed with a threaded groove and is mounted on the inner ring of the return pipe, so that the internal shaking path of the nozzle is limited by the mounting block. The mounting block is fixed inside by the screw block. The mounting block and the oil return pipe limit the screw block on all sides, and a compression spring is installed on the screw block. The screw block is connected to the inner wall of the shell through the two ends of the compression spring. When the pressure is too large, the compression spring and the screw block cooperate to fix the mounting block in the oil return pipe. The compression spring deforms to reduce the pressure, reducing the risk of loosening of the mounting block, thereby strengthening the influence of the mounting block on the fuel nozzle. The brushes inside the shell are sealed by the sealing cover, and the shell and the sealing cover are fixedly connected by the screw. The friction of the contact surface with the sealing cover is enhanced by the uneven locking nut. The locking nut reinforces the connection between the sealing cover and the shell, thereby improving the stability of the fuel pump.

[0009] Furthermore, a screw block is threaded onto the inner wall of the mounting block, one end of which is sheathed with a compression spring, the other end of which extends to the inner wall of the housing. This arrangement allows the compression spring to be installed on the screw block during use, connecting the screw block to the inner wall of the housing via the two ends of the compression spring. When pressure is excessive, the compression spring and screw block cooperate to secure the mounting block within the oil return pipe, causing the compression spring to deform and reduce the pressure, thereby reducing the risk of the mounting block loosening.

[0010] Furthermore, the outer shell is surrounded by interfaces and oil outlet pipes. A sealing nut is threaded onto the inner wall of the oil outlet pipe, and a flange is provided on one side of the outer shell. This arrangement ensures that when the fuel pump is in use, the oil outlet pipe is used to connect to the connecting pipe to transport fuel, while the sealing nut seals the unused oil outlet pipe to prevent dust from entering the outer shell.

[0011] Furthermore, an armature is mounted on the inner wall of the housing, and a brush is mounted on the inner wall of the housing near the armature. The purpose of this arrangement is that during the use of the fuel pump, the armature and the brush cooperate to enable the fuel assembly to perform fuel delivery work.

[0012] Furthermore, a sealing cover is provided on one side of the outer shell close to the brush, and the brush is rotatably connected to the inner wall of the sealing cover. The purpose of this setting is that during the use of the fuel pump, the brush inside the outer shell is sealed by the sealing cover, and the outer shell and the sealing cover are fixedly connected by a screw.

[0013] Furthermore, screws are threadedly connected to the inner walls around the outer shell close to the sealing cover. One end of the four screws penetrates the sealing cover, and locking nuts are threadedly connected to the outer walls of the four screws. The locking nuts are located on the outer wall of the sealing cover. The purpose of this setting is that during the use of the fuel pump, the uneven locking nuts enhance the friction force of the contact surface with the sealing cover, and the locking nuts reinforce the connection between the sealing cover and the outer shell, improving the stability of the fuel pump.

[0014] The utility model has the following beneficial effects:

[0015] (1) Through the settings of the washer, the mounting block and the compression spring, the washer fills the gap between the nozzle and the return pipe, enhancing the sealing performance of the fuel pump. Threaded grooves are designed on the mounting block, and the mounting block is installed on the inner circle of the return pipe, so that the internal shaking path of the nozzle is limited by the mounting block. The inside of the mounting block is fixed by the screw block, and at the same time, the mounting block and the return pipe limit the periphery of the screw block. The compression spring cooperates with the screw block to fix the mounting block in the return pipe, improving the stability of the fuel pump.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
