[0030] The fuel filter 5 is a fuel purifying device, which is usually composed of multiple layers of filter paper or composite materials inside, for filtering impurities, moisture and colloid in fuel, achieving the effect of supplying clean fuel to the engine, protecting the fuel pump 6 and the fuel injector 7 from clogging and wear, which is well known, and will not be described in detail here. The fuel pump 6 is an electrically driven vane pump or plunger pump, which functions to pressurize the fuel in the fuel tank 1 to provide high-pressure fuel with sufficient pressure to the fuel injector 7 to ensure good fuel atomization, and is the core component of the electronic injection system, which is prior art and will not be described in detail here. The fuel injector 7 is an electromagnetic valve type fuel injection device, which is composed of an electromagnetic coil, a valve needle, a spray hole and the like, and precisely controls the fuel injection amount and timing after receiving the electric pulse signal from the ECU, achieving the effect of atomizing and injecting high-pressure fuel into the intake manifold or cylinder, which is prior art and will not be described in detail here.
[0031] The fixing mechanism includes a mounting bracket 24, a clamping plate one 27 and a clamping plate two 28, which is used to stably fix the fuel filter 5 inside the motorcycle shell. The mounting bracket 24 is internally threaded with a bolt 25, which is connected with the motorcycle shell through the bolt 25. After the bolt 25 is passed through the reserved hole on the motorcycle shell and tightened, the phenomenon of loosening or falling off of the entire mechanism due to bumps and vibrations during driving is avoided. The mounting bracket 24 is fixedly connected with support blocks 26 on the side wall, and the support blocks 26 are fixedly connected with a fixed shaft. The clamping plate one 27 and the clamping plate two 28 are both rotatably connected on the side wall of the fixed shaft, and the clamping plate one 27 and the clamping plate two 28 are slidably connected. The fuel filter 5 is arranged between the clamping plate one 27 and the clamping plate two 28, and the clamping plate one 27 and the clamping plate two 28 rotate together with the fixed shaft. The fixed shaft serves as a pivot, allowing the two clamping plates to swing slightly within a small range around it, achieving the effect of forming a pincer-shaped clamping structure.

The side walls of the clamping plate one 27 and the clamping plate two 28 are both fixedly connected with side plates 29, and the mounting bracket 24 and the side plates 29 are both fixedly connected with second springs 30. The second springs 30 are used to continuously exert a supporting force on the side plates 29, thereby driving the clamping plate one 27 and the clamping plate two 28 connected thereto to rotate inward around the fixed shaft, achieving the effect of automatically and continuously exerting a clamping force on the fuel filter 5 placed between the two clamping plates by the elastic potential energy of the spring, firmly fixing it. The clamping plate one 27 and the clamping plate two 28 are S-shaped, and the openings of the two are expanded outward, which plays a guiding and positioning role when installing the fuel filter 5, so that the fuel filter 5 can be easily pushed into the clamping plate one 27 and the clamping plate two 28.
[0032] The quick release head comprises a connecting head 19 fixedly connected at the oil inlet and outlet of the pump body 2, fuel filter 5, fuel pump 6 and fuel injector 7, the connecting head 19 being a male part of the quick release head, one end of which is used to be fixedly connected with the oil inlet or outlet of the pump body 2, fuel filter 5, fuel pump 6 and fuel injector 7, thereby achieving the effect of providing a standardized quick plug-in interface for these oil supply components, the side wall of the connecting head 19 is fixedly connected with a fixing ring one 20 and a fixing ring two 21, and an annular groove 22 is arranged between the fixing ring one 20 and the fixing ring two 21, when the connecting head 19 is inserted into the clamping head, the clamping beads 17 inside the clamping head will automatically be embedded into the annular groove 22, thereby achieving the effect of firmly locking the two heads and preventing accidental falling due to oil pressure or vibration.
[0033] The clamping head comprises a connecting ring 9 and a fixed pipe 11, the clamping head being a female part of the quick release head, cooperating with the connecting head 19, the oil pipe 8 being fixedly connected at both ends of the oil pipe 8, the fixed pipe 11 being fixedly connected at the side wall of the connecting ring 9, the side wall of the connecting head 19 being slidingly connected inside the fixed pipe 11, the side wall of the connecting head 19 being axially slidingly connected with the inner wall of the fixed pipe 11 when the connecting head 19 is connected. At the same time, the clamping block 23 on the connecting head 19 is slidingly inserted into the groove 18 inside the fixed pipe 11, thereby achieving the effect of guiding during connection, preventing relative rotation of the two and ensuring correct positioning of the internal sealing ring, the fixed pipe 11 is internally provided with an annular array of connecting heads 19, the side wall of the fixing ring one 20 is fixedly connected with an annular array of clamping blocks 23, the side wall of the clamping block 23 is slidingly connected inside the groove 18, the fixed pipe 11 is externally provided with a sleeve 12, the inner ring of the sleeve 12 is fixedly connected with a pressing block 13, the side wall of the pressing block 13 is slidingly connected with the side wall of the fixed pipe 11, the fixed pipe 11 is externally provided with a first spring 15, one end of the first spring 15 being fixedly connected with the side wall of the connecting ring 9, the other end of the first spring 15 being fixedly connected with the side wall of the pressing block 13, the first spring 15 being used to continuously apply an axial thrust to the pressing block 13, since the pressing block 13 and the sleeve 12 are of an integrated structure, thereby driving the entire sleeve 12 to always remain in the locked position, the fixed pipe 11 is internally provided with a recess hole 16, the recess hole 16 being conical with a small inner diameter and a large outer diameter, the recess hole 16 being arranged in an annular array, the recess hole 16 is internally slidingly connected with clamping beads 17, the clamping beads 17 can be arranged inside the annular groove 22;
[0034] In the locking state, the first spring 15 pushes the sleeve 12, and the inner wall of the sleeve 12 matches the inner small and outer large conical recess 16 to extrude the clamping bead 17 in the radial direction. The extruded clamping bead 17 matches the annular groove 22 on the connector 19 to be clamped, thereby firmly locking the connector 19 in the fixed tube 11 in the axial direction, achieving a safe and reliable connection effect. When unlocking, the operator pulls the sleeve 12 backward, and the inner wall of the sleeve 12 is displaced backward, thereby providing space for the clamping bead 17 to move in the radial direction in the tapered space of the recess 16. At this time, the clamping bead 17 is released from the constraint of the annular groove 22, achieving the effect of unlocking the connector 19, and the connector 19 can be easily pulled out.
[0035] The sleeve 12 is fixedly connected with the anti-skid ring 14, which is used to increase the friction between the operator's fingers and the outer wall of the sleeve 12, thereby avoiding the phenomenon of slipping when it is contaminated with oil or liquid. The connection between the oil pipe 8 and the connecting ring 9 is fixedly connected with the reinforcing sleeve 10, which is used to enhance the structural strength and sealing performance of the connection between the oil pipe 8 and the connecting ring 9, thereby avoiding the phenomenon of loosening, wear or fuel leakage due to bending or vibration of the oil pipe 8, and improving the durability and safety of the connection.
[0036] Working principle: When the oil supply system is working, the fuel pump 6 is started to draw fuel from the fuel tank 1, and the fuel flows through the oil pipe 8 connected with the quick release head by the connector, is filtered in the fuel filter 5, and is then transported to the oil injector 7 through the oil pipe 8, and finally is sprayed into the engine for combustion. In this process, when any component needs to be repaired or replaced and the oil pipe 8 needs to be disassembled during subsequent maintenance, the operator can pull the sleeve 12 in the axial direction away from the connector 19, thereby extruding the first spring 15 to make it deform, and making the sleeve 12 displace backward to provide space for the clamping bead 17 in the recess 16 to move in the radial direction. By pulling, the clamping bead 17 can be released from the annular groove 22 in the connector 19, and the connector 19 can be easily pulled out of the fixed tube 11 to quickly disconnect the oil circuit. At the same time, when the fuel filter 5 needs to be disassembled for cleaning, the operator only needs to apply an outward force to make the clamping plate one 27 and the clamping plate two 28 deflect outward to overcome the supporting force of the second spring 30 and open outward, thereby releasing the clamping of the fuel filter 5 and taking it out of the fixing mechanism for replacement, thereby reducing the difficulty of disassembling the components during maintenance and improving the work efficiency.
