Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology and relates to a novel fuel supply system structure. Background Technology

[0002] Motorcycles are currently an important means of transportation. In the use of gasoline-powered motorcycles, the fuel supply system is an important component, which provides fuel to the engine to achieve power output.

[0003] Traditional gasoline-powered motorcycles typically use a single fuel tank structure for their fuel supply system, which is installed at the front of the frame. When using this method, we found that firstly, the fuel capacity of the single fuel tank is limited, affecting the range of the gasoline-powered motorcycle. Secondly, the high-pressure fuel line between the single fuel tank and the throttle body is too long, and the lines are prone to getting tangled and bundled together, which poses a risk of wear and tear. Furthermore, it is quite difficult to maintain in the future. Summary of the Invention

[0004] The purpose of this invention is to provide a novel fuel supply system structure to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel fuel supply system structure includes a frame, an upper fuel reservoir fixedly installed at the front of the frame, a fuel tank fixedly installed at the bottom of the frame, the fuel tank connected to the upper fuel reservoir via a pipeline, a fuel filter fixedly installed at the front of the fuel tank and fixedly connected to the frame, the fuel filter's inlet end communicating with the inside of the fuel tank, the fuel filter's outlet end fixedly connected to a high-pressure fuel line, an engine fixedly installed at the rear of the fuel tank and fixedly connected to the frame, a throttle valve body fixedly installed at the engine's inlet end, and the high-pressure fuel line fixedly connected to the throttle valve body's inlet end.

[0006] In the above-mentioned novel fuel supply system structure, the top of the upper oil reservoir is provided with a filling port, the top of the filling port is threaded with a sealing plug, and a steel wire filter screen is fixedly provided at the bottom of the filling port.

[0007] In the above-mentioned novel fuel supply system structure, a fixing ring is fixedly provided on the surface of the fuel filter, and a buckle is provided on the side of the fixing ring. A filter mounting bracket is welded to the bottom of the frame, and a plug is fixedly provided on the side of the filter mounting bracket. The plug is inserted into the buckle.

[0008] In the aforementioned novel fuel supply system structure, the size of the insert block is adapted to the inner diameter of the buckle.

[0009] In the above-mentioned novel fuel supply system structure, multiple oil pipe combination brackets are nested at equal intervals on the surface of the high-pressure oil pipe, and a connecting piece is fixedly provided on one side of the multiple oil pipe combination brackets. The connecting piece is fixedly connected to the vehicle frame by locking bolts.

[0010] In the above-mentioned novel fuel supply system structure, the volume of the upper oil reservoir is at least 2L, and the volume of the fuel tank is at least 8L.

[0011] Compared with the prior art, the advantages of this novel fuel supply system structure are as follows: by combining the upper fuel reservoir and the fuel tank, the fuel storage capacity is effectively increased compared with the traditional single fuel tank structure, thus effectively increasing the range during motorcycle use. At the same time, by mounting the fuel tank at the bottom of the frame, the fuel filter and high-pressure fuel line can be directly connected to the bottom fuel tank, replacing the traditional method of placing them at the upper fuel reservoir. This effectively reduces the problem of long high-pressure fuel line routing and avoids the risk of wear and tear and maintenance difficulties caused by the wires being tangled and bundled together.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-6 As shown, this utility model discloses a novel fuel supply system structure, including a frame 1. A fuel reservoir 2 is fixedly installed at the front of the frame 1, and a fuel tank 3 is fixedly installed at the bottom of the frame 1. The fuel tank 3 is connected to the fuel reservoir 2 by a pipeline. A fuel filter 6 is fixedly installed at the front of the fuel tank 3 and fixedly connected to the frame 1. The fuel inlet of the fuel filter 6 is connected to the inside of the fuel tank 3, and a high-pressure fuel pipe 5 is fixedly connected to the fuel outlet of the fuel filter 6. An engine is fixedly installed at the rear of the fuel tank 3 and fixedly connected to the frame 1. A throttle valve body 4 is fixedly installed at the fuel inlet of the engine, and the high-pressure fuel pipe 5 is fixedly connected to the fuel inlet of the throttle valve body 4.

[0021] Specifically, by combining the upper oil reservoir 2 and the fuel tank 3, the fuel storage capacity is effectively increased compared to the traditional single fuel tank structure, thus effectively increasing the range during motorcycle use. At the same time, by mounting the fuel tank 3 at the bottom of the frame 1, the fuel filter 6 and the high-pressure fuel line 5 can be directly connected to the bottom fuel tank 3, replacing the traditional method of placing them at the upper oil reservoir 2. This effectively reduces the problem of long high-pressure fuel line 5 wiring and avoids the risk of wear and tear and maintenance difficulties caused by the wires being tangled and bundled together.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a novel fuel supply system structure. The top of the upper oil reservoir 2 is provided with a filling port, the top of the filling port is threaded with a sealing plug, and a steel wire filter screen 201 is fixedly provided at the bottom of the filling port.

[0023] Specifically, the steel wire filter 201 at the bottom of the filler neck prevents impurities from entering during refueling, which could cause blockage of the fuel line and affect engine life.

[0024] A fixing ring is fixedly provided on the surface of the fuel filter 6, and a buckle 8 is provided on the side of the fixing ring. A filter mounting bracket 9 is welded to the bottom of the frame 1. A plug 10 is fixedly provided on the side of the filter mounting bracket 9. The plug 10 is inserted into the buckle 8, and the size of the plug 10 is adapted to the inner diameter of the buckle 8.

[0025] Specifically, the fuel filter 6 is secured by inserting the plug 10 on the side of the filter mounting bracket 9 into the buckle 8 on the side of the fixing ring.

[0026] Multiple oil pipe combination brackets 7 are nested at equal intervals on the surface of the high-pressure oil pipe 5. A connecting piece 11 is fixedly provided on one side of the multiple oil pipe combination brackets 7. The connecting piece 11 is fixedly connected to the frame 1 by locking bolts 12.

[0027] Specifically, the oil pipe assembly bracket 7 can be connected to the vehicle frame 1 through the cooperation of the connecting piece 11 and the locking bolt 12. The oil pipe assembly bracket 7 makes the routing of the high-pressure oil pipe 5 and the throttle cable clear and orderly, reducing the risk of the high-pressure oil pipe 5 being worn out after long-term use.

[0028] The capacity of the upper oil container 2 is at least 2L, and the capacity of the oil tank 3 is at least 8L.

[0029] Specifically, by combining the oil can 2 and the oil tank 3, the oil storage capacity of the motorcycle is effectively increased, thereby improving the motorcycle's range.

[0030] Specifically, by setting up two oil storage structures, the upper oil reservoir 2 and the oil tank 3, the upper oil reservoir 2 is located at the front of the frame 1, and the oil tank 3 is located at the bottom of the frame 1. The upper oil reservoir 2 and the oil tank 3 are connected by pipeline. This arrangement effectively increases the motorcycle's oil storage capacity, thereby increasing its range. At the same time, the fuel filter 6 and the high-pressure oil pipe 5 can be directly installed at the bottom oil tank 3, without needing to be installed at the upper oil reservoir 2. This effectively reduces the length of the high-pressure oil pipe 5, achieving a compact arrangement of the oil tank 3, fuel filter 6, and throttle body 4, while also reducing the overall weight of the vehicle and mitigating the risk of wiring wear caused by the long routing of the high-pressure oil pipe 5.
