Description

Technical Field

[0001] This invention relates to motorcycle parts, and more particularly to a motorcycle fuel pump assembly with an integrated electronic control unit. Background Technology

[0002] Currently, Chinese patent CN213419249U discloses a motorcycle fuel pump assembly, including a base. A regulating valve is located on top of the base, and a fuel pump is located on the right side of the base. A filter mechanism is connected to the right side of the fuel pump. A wire interface is located at the upper left end of the fuel pump, and a fuel pump outlet pipe is located below the wire interface. A fuel pump inlet pipe is located at the right end of the fuel pump. A fuel pump housing is also located on the right side of the fuel pump housing, and an inlet pipe is located on the right side of the inlet pipe, connecting to the filter mechanism. The filter mechanism includes a filter screen connected to the inlet pipe, and a bracket that encloses the filter screen. A mounting buckle is located on the outside of the bracket, and the bracket is fixed to the fuel pump base via the mounting buckle. A fuel outlet nozzle is located below the base, and the upper end of the fuel outlet nozzle communicates with the regulating valve mounting base. However, when the above-mentioned fuel pump assembly is needed, it needs to be connected to the electronic control unit installed on the motorcycle via a wire. Due to the limited space available for movement during installation, the above-mentioned fuel pump assembly has the disadvantage of being inconvenient to install. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a motorcycle fuel pump assembly with an integrated electronic control unit, which has the advantage of being relatively easy to install.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a motorcycle fuel pump assembly with an integrated electronic control unit, including a mounting base, a fuel pump body disposed on the top of the mounting base, and a filter mechanism disposed on the top of the fuel pump body. The mounting base has a through-hole for wiring, and the electronic control unit is disposed at the bottom of the mounting base. The signal line of the electronic control unit passes through the through-hole and connects to the fuel pump body. A fixing claw is disposed on one side of the mounting base, the side wall of the fixing claw is close to the electronic control unit, and the end of the fixing claw abuts against the bottom surface of the electronic control unit. A movable claw is hinged to the other side of the mounting base. When the side wall of the movable claw rotates to be close to the mounting base, the end of the movable claw abuts against the bottom surface of the electronic control unit. A limit screw is rotatably connected to the movable claw, and the limit screw is used to thread into the mounting base, thereby pressing and fixing the movable claw to the mounting base.

[0005] By integrating the electronic control unit (ECU) into the fuel pump body using the above technical solution, installation of the fuel pump assembly only requires connecting the ECU to the pre-installed wiring on the motorcycle, offering a significant advantage in installation convenience. The fixed and movable jaws work together to limit the ECU's movement, improving the connection stability between the ECU and the fuel pump body. The movable jaw is secured to the mounting base by a limiting screw, making the installation and removal of the ECU even more convenient and faster.

[0006] Preferably, the side wall of the mounting base is provided with a strap, and the end of the strap is tied and fixed to the threaded section of the limiting screw.

[0007] Through the above technical solution, the end of the strap is tied and fixed to the threaded section of the limit screw to limit the limit screw and avoid the situation where the electronic control unit cannot be stably connected to the mounting base due to the loss of the limit screw.

[0008] Preferably, the bottom of the mounting base is provided with a storage slot, a fan is provided in the storage slot, and a plurality of ventilation holes are provided at the top of the storage slot, and the plurality of ventilation holes all penetrate the top surface of the mounting base.

[0009] With the above technical solution, when in use, the fan is connected to the motorcycle battery to drive airflow, thereby cooling the electronic control unit and the fuel pump body.

[0010] Preferably, the filtration mechanism includes a filter housing and a filter screen. The top of the filter housing is connected to the motorcycle's fuel tank, and the bottom of the filter housing is connected to the fuel inlet of the fuel pump body. The filter screen is disposed inside the filter housing to filter the flowing oil.

[0011] Through the above technical solution, the filter screen can be used to filter the flowing oil, preventing impurities from entering the engine and ensuring the engine's service life.

[0012] Preferably, the inner hole of the filter housing is square, the filter screen is slidably connected in the inner hole of the filter housing, a support seat is threadedly connected in the filter housing, an upper spring is connected between the support seat and the filter screen, and an opening and closing mechanism is provided in the filter housing. When the filter screen slides down to the point of being vertically misaligned with the opening and closing mechanism, the opening and closing mechanism closes.

[0013] With the above technical solution, the upper spring drives the filter screen to be positioned inside the opening and closing mechanism. When there are many impurities on the top of the filter screen, the filter screen's permeability decreases, and the oil will drive the filter screen to move downwards. When there are many impurities on the top of the filter screen, the filter screen moves downwards to a position that is vertically misaligned with the opening and closing mechanism. At this time, the opening and closing mechanism closes, the motor control unit shuts off the motorcycle, and the user can replace the filter screen without emptying the oil tank.

[0014] Preferably, two receiving slots are symmetrically arranged on the inner wall of the filter housing, and the opening and closing mechanism includes an opening and closing unit disposed in the two receiving slots. The opening and closing unit includes a flap hinged to the inner wall of the bottom of the receiving slot and a return spring disposed in the receiving slot. The two ends of the return spring are respectively connected to the mounting base and the flap.

[0015] With the above technical solution, when the filter screen is located between the two flaps, the filter screen supports the flaps, keeping the return spring under pressure. When the filter screen is misaligned with the two flaps, the return spring can use its elastic force to drive the flaps out of the receiving groove. When the two flaps are pressed together, they cooperate to separate the inner hole of the filter housing. Using the movement of the filter screen to complete the opening and closing mechanism offers greater ease of use.

[0016] Preferably, the two opening and closing units are a left opening and closing unit and a right opening and closing unit, the length of the flap in the left opening and closing unit is greater than the length of the flap in the right opening and closing unit, and a stop is provided at the bottom of the flap in the left opening and closing unit to abut against the flap in the right opening and closing unit.

[0017] With the above technical solution, the length of the flap in the left opening and closing unit is greater than the length of the flap in the right opening and closing unit, and a stop is provided at the bottom of the flap in the left opening and closing unit. This can effectively prevent the two flaps from not being able to fit together properly, so that the opening and closing unit can operate normally.

[0018] Preferably, the flap includes a flip-outer sleeve hinged to the inner wall of the receiving groove, a sliding inner core slidably disposed inside the flip-outer sleeve, and an outward push spring disposed inside the flip-outer sleeve. A connecting through hole one is provided through the flip-outer sleeve, and a connecting through hole two is provided through the sliding inner core. The two ends of the outward push spring are respectively connected to the flip-outer sleeve and the sliding inner core. The outward push spring drives the sliding inner core to protrude from the flip-outer sleeve by elastic force, so that the connecting through hole one and the connecting through hole two are connected. The stop block has a receiving groove facing the left opening and closing unit. A pressure block is slidably disposed in the receiving groove, and the pressure block is connected to the sliding inner core.

[0019] With the above technical solution, when the flaps rotate out of the receiving groove and are not pressed together, the end of the movable inner core protrudes from the flipping outer sleeve, and the connecting through hole one and the connecting through hole two are in a connected state. At this time, the flow of oil is less obstructed. When the end of the movable inner core in the right opening and closing unit abuts against the flipping outer sleeve in the left opening and closing unit, the movable inner core in the right opening and closing unit gradually slides into the flipping outer sleeve on the same side. When the flipping outer sleeve in the right opening and closing unit abuts against the pressure block in the left opening and closing unit, the flipping outer sleeve in the right opening and closing unit will drive the movable inner core in the left opening and closing unit to slide into the flipping outer sleeve on the same side through the pressure block, so that the connecting through hole one and the connecting through hole two are misaligned, thereby blocking the inner hole of the filter housing.

[0020] Preferably, the top surface of the sliding inner core is provided with a rubber positioning protrusion, and when the sliding inner core is housed inside the flip-outer sleeve, the rubber positioning protrusion is engaged in the first connecting through hole.

[0021] Through the above technical solution, the rubber positioning protrusion is inserted into the first connecting through hole to limit the relative sliding of the flipped outer jacket and the sliding inner core, so as to avoid the situation where the first connecting through hole and the second connecting through hole are connected during the isolation process, and to ensure the blocking effect of the opening and closing mechanism on the inner hole of the filter housing.
