Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a motorcycle fuel tank and a motorcycle. Background Technology

[0002] In most motorcycles, the fuel tank is located in front of the seat and above the engine. To increase range, the fuel tank capacity is typically increased by mounting it on a single main beam tube of the frame. When the fuel tank is filled with fuel, it also carries weight. This design results in a high center of gravity for the motorcycle, with the fuel tank's center of gravity concentrated directly above the engine cylinder head. Consequently, the motorcycle's handling becomes poor, especially on unpaved roads.

[0003] Therefore, how to improve the motorcycle's handling by adjusting the fuel tank's center of gravity, thereby adjusting the overall center of gravity, while ensuring a large fuel tank capacity, is a technical problem that urgently needs to be solved in the current technology.

[0023] Figure 1 This is a top view of the fuel tank of this utility model installed at the rear of a motorcycle. Figure 2 This is a schematic diagram of the fuel tank structure. Figure 3 for Figure 2 Side view, Figure 4 for Figure 3 A sectional view along the BB direction, such as Figure 1-4As shown: The motorcycle fuel tank of this embodiment includes a tank body 1. The tank body 1 has a main fuel storage chamber 2. The two sides of the main fuel storage chamber 2 are recessed to form recessed secondary chambers 4. The main fuel storage chamber 2 extends rearward to form a rearward extended secondary chamber 8. The main fuel storage chamber 2 is provided with a filler port. The left and right sides of the main fuel storage chamber 2 (relative to the left and right direction of the motorcycle) extend downward (relative to the up and down direction of the motorcycle) to form recessed secondary chambers 4. The recessed secondary chambers 4 are connected to the main fuel storage chamber 2. The main fuel storage chamber 2 extends rearward and downward to form the rearward extended secondary chamber 8. The rearward extended secondary chamber 8, the main fuel storage chamber 2, and the recessed secondary chambers 4 are interconnected. Therefore, during use, the center of gravity of the motorcycle can be adjusted by adjusting the center of gravity of the fuel tank. The main center of gravity of the fuel tank can be adjusted to be located in the middle of the vehicle, near the lower part of the driver. Compared with the prior art, this is beneficial to lowering the center of gravity of the vehicle and improving riding comfort.

[0024] In this embodiment, the housing 1 is further provided with two communicating chambers 3. The two communicating chambers 3 are respectively located on both sides of the main oil storage chamber 2 and extend downwards to connect with the two sunken auxiliary chambers 4. The communicating chambers 3 are located between the main oil storage chamber 2 and the sunken auxiliary chambers 4. By setting up the communicating chambers 3, it is convenient to form and process the housing 1. At the same time, the sunken auxiliary chambers 4 are set on both sides of the motorcycle frame steering column when in use, which is equivalent to adding a balancer to the front wheel steering system, which helps to improve the front wheel steering handling.

[0025] In this embodiment, the inner side of the recessed secondary chamber 4 is provided with a mounting groove 401. In use, the mounting groove 401 is used to partially accommodate the air intake pipe of the motorcycle air filter. The shape of the mounting groove 401 is adapted to the shape of the air intake pipe, which is generally a circular pipe. Therefore, the mounting groove 401 is a semi-cylindrical groove. By setting the mounting groove 401, the air intake pipe can be protected to a certain extent, and it is also convenient for the arrangement and assembly of the air intake pipe.

[0026] In this embodiment, a fuel pump 9 is provided inside the rear extension sub-chamber 8. The fuel pump 9 is located at the bottom of the rear extension sub-chamber 8.

[0027] In this embodiment, the bottom of the recessed secondary chamber 4 is provided with a mounting positioning hole for detachable and fixed connection with the motorcycle frame. The bottom is the bottom relative to the vertical direction of the motorcycle. In use, the mounting positioning hole is detachably and fixedly connected to the connecting lug on the lower main tube of the motorcycle frame.

[0028] In this embodiment, the rear extension sub-chamber 8 is provided with a mounting and fixing groove 801 for connecting with the motorcycle's electrical component box. The mounting and fixing groove 801 is provided on the side wall of the rear extension sub-chamber 8, thereby providing a protrusion on the electrical component box to form a fitting structure for fixation, and also facilitating the positioning and assembly of the fuel tank.

[0029] In this embodiment, the lowest point of the oil storage in the submerged secondary chamber 4 is provided with a connection port, and a pipe connector 5 is provided on the connection port. The pipe connector 5 of the submerged secondary chamber 4 on the left side is connected to the pipe connector 5 of the submerged secondary chamber 4 on the right side through oil pipe I 6; oil pipe II 7 is connected to oil pipe I 6 through a tee pipe.

[0030] The fuel pump 9 is connected to the fuel pipe I6 via fuel pipe II7. The two recessed auxiliary chambers 4 are connected to the main fuel storage chamber 2, and the two recessed auxiliary chambers 4 are interconnected via fuel pipe I6. At the same time, fuel pipe I6 is connected to the fuel pump 9 located in the rear extended auxiliary chamber 8 via fuel pipe II7. Thus, during the entire vehicle operation, the fuel quantity can be dynamically and adaptively adjusted according to the main center of gravity (the center of gravity of the main fuel storage chamber 2 and the rear extended auxiliary chamber 8) and the two secondary centers of gravity (the center of gravity of the recessed auxiliary chambers 4). This allows the fuel tank to maintain a good balance in any usage state, from a full tank to when it is almost empty, thus improving the handling comfort of the motorcycle under various road conditions and providing a longer driving range.

[0031] In this embodiment, the housing 1 is integrally molded. The integrally molded structure of the housing 1 facilitates molding and processing.

[0032] The motorcycle in this embodiment includes the aforementioned motorcycle fuel tank. For example... Figure 1 As shown in the diagram, the dotted line represents the fuel tank.
