Description

Technical Field

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

[0002] Motorcycle fuel tanks are connected to the frame only through a few fixed points. During vehicle operation, especially when traversing bumpy roads or accelerating and decelerating rapidly, they are prone to shaking. This shaking not only increases the overall vibration and noise of the motorcycle but may also cause the fuel tank to rub against and collide with surrounding components, accelerating wear and tear over time. Furthermore, the area directly in front of the fuel tank is protected from direct airflow due to the protrusion of the fuel tank and the front of the motorcycle. Therefore, after prolonged riding in hot weather, the obstructed airflow cannot effectively dissipate the heat generated on the fuel tank surface by engine cooling and sunlight, causing the temperature of the fuel tank and surrounding seat area to rise. Prolonged contact with these hot areas can easily lead to discomfort and reduced riding comfort. In addition, in the event of a collision, because the fuel tank is close to the rider's body and generally lacks the ability to disperse impact force, the impact force is directly transmitted to the rider through the fuel tank, causing serious injury. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a motorcycle fuel tank air guide structure that increases the stability of the fuel tank after installation, facilitates the guidance of airflow on the surface of the fuel tank, reduces the discomfort caused by the rider's body being in prolonged contact with the fuel tank and seat due to heat, and mitigates the impact of collision on the rider.

[0004] This utility model also provides a motorcycle fuel tank air guiding structure, comprising: a fuel tank body, with air guiding inclined surfaces on both the front and rear sides of the fuel tank body; a mounting ring fixedly connected to the right end of each air guiding inclined surface; a pressure plate rotatably connected to the right end of the upper surface of the fuel tank body; the pressure plate contacting the upper surface of the motorcycle seat; support side plates fixedly connected to both the front and rear surfaces of the pressure plate; a mounting shell fixedly connected to the upper surface of the pressure plate; a support spring fixedly connected inside the mounting shell; a baffle fixedly connected to the right end of the support spring; and a sponge contact block fixedly connected to the surface of the baffle. This improves the stability of the fuel tank and guides the airflow generated during riding to the parts where the rider contacts the fuel tank and seat, reducing discomfort caused by the fuel tank.

[0005] According to the motorcycle fuel tank air guide structure described in this utility model, a waterproof cloth cover is fixedly connected between the mounting shell and the baffle, and the waterproof cloth cover completely covers the support spring, reducing the risk of damage to the support spring.

[0006] According to the motorcycle fuel tank air guide structure of this utility model, a groove is provided on the left surface of the sponge contact block, and the baffle is located inside the groove. This improves the effectiveness of the sponge contact block.

[0007] According to the motorcycle fuel tank air guide structure described in this utility model, the pressure plate and the supporting side plate are made of elastic plastic, and both the surface of the supporting side plate and the mounting shell are provided with arc-shaped sealing edges. This reduces the risk of injury to the rider from the pressure plate and the supporting side plate.

[0008] According to the motorcycle fuel tank air guide structure of this utility model, a silicone suction cup is fixedly connected to the upper surface of the mounting shell. When installing the fuel tank, the suction end of the silicone suction cup contacts the upper surface of the fuel tank body, thus improving the convenience of fuel tank installation. Beneficial effects

[0009] The motorcycle fuel tank airflow structure of this technical solution uses a pressure plate, a supporting side plate, and an airflow ramp. The pressure plate provides additional restraint to the fuel tank, increasing its stability. At the same time, the supporting side plate provides additional support to the thigh area and works with the airflow ramp to deliver airflow to the thigh area, alleviating the discomfort caused by prolonged contact between the thigh and the fuel tank and seat. The mounting shell, supporting spring, and foam contact block utilize elasticity to mitigate the impact force on the rider's face when facing the fuel tank, reducing the discomfort caused by the motorcycle fuel tank to the rider.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model discloses a motorcycle fuel tank air guide structure, comprising: a fuel tank body 1, with air guide slopes 8 on both the front and rear sides of the fuel tank body 1. The air guide slopes 8 are used to reduce the resistance of the fuel tank and affect the flow direction of the airflow. A mounting ring 9 is fixedly connected to the right end of the air guide slopes 8. A pressure plate 2 is rotatably connected to the right end of the upper surface of the fuel tank body 1. The pressure plate 2 contacts the upper surface of the motorcycle seat. The pressure plate 2 is used to increase the contact area between the fuel tank body 1 and the seat, and to increase the restriction on the fuel tank. Support side plates 3 are fixedly connected to both the front and rear surfaces of the pressure plate 2. The pressure plate 2 and the support side plates 3 are made of elastic plastic, and the surfaces of the support side plates 3 and the mounting shell 4 are provided with arc-shaped sealing edges. The support side plates 3 are used to provide additional support for the legs and at the same time provide conditions for the airflow to remove heat from the legs.

[0019] Specifically, the fuel tank body 1 is fixed to the rear of the motorcycle, and the rider's thighs are directly pressed against the surface of the support side plate 3. The support side plate 3, made of elastic plastic, avoids being too hard and affecting the comfort of the legs. During riding, the airflow flows to the lower right through the wind guide slope 8. As the airflow flows to the right, it passes under the arc-shaped support side plate 3, thereby carrying away the heat generated in the thigh area.

[0020] A mounting shell 4 is fixedly connected to the upper surface of the pressure plate 2. A silicone suction cup 12 is fixedly connected to the upper surface of the mounting shell 4. When installing the oil tank, the suction end of the silicone suction cup 12 contacts the upper surface of the oil tank body 1. The silicone suction cup 12 is used to limit the range of motion of the pressure plate 2. A support spring 10 is fixedly connected inside the mounting shell 4. A baffle 7 is fixedly connected to the right end of the support spring 10. A waterproof cloth cover 5 is fixedly connected between the mounting shell 4 and the baffle 7. The waterproof cloth cover 5 completely covers the support spring 10. The waterproof cloth cover 5 is used to isolate the support spring 10 and prevent damage to the support spring 10. A sponge contact block 6 is fixedly connected to the surface of the baffle 7. A groove 11 is provided on the left surface of the sponge contact block 6. The baffle 7 is located inside the groove 11. The support spring 10 cooperates with the baffle 7 and the sponge contact block 6 to mitigate the negative impact of collision. The baffle 7 is made of silicone.

[0021] Specifically, during fuel tank installation, the upper pressure plate 2 causes the silicone suction cup 12 on the surface of the mounting shell 4 to adhere to the surface of the fuel tank body 1, thereby preventing the pressure plate 2 from affecting the fuel tank fixing process during fuel tank installation. After the fuel tank and the seat are fixed in sequence, the pressure plate 2 is flipped down, pressing the pressure plate 2 onto the surface of the seat. Under normal conditions, the sponge contact block 6 does not contact the body. In the event of a collision, the rider slides forward due to inertia and approaches the fuel tank. As the body approaches the fuel tank, the body first contacts the sponge contact block 6. During the continuous forward sliding, the sponge contact block 6 is compressed and the thrust is transmitted to the support spring 10 through the baffle 7. The support spring 10 is compressed after being stressed. At this time, the stress generated during the deformation of the sponge contact block 6, the support spring 10, and the silicone baffle 7 alleviates the impact force of the collision.

[0022] Working principle: When installing the motorcycle, flip the pressure plate 2 upwards so that the silicone suction cup 12 on the surface of the mounting shell 4 adheres to the surface of the fuel tank body 1. At this time, the pressure plate 2 will not naturally flip downwards. Then, manually align it with the fuel tank mounting bracket and fix the fuel tank and the pressure plate 2 behind the seat in sequence. Use the pressure plate 2 to press the seat. The pressure plate 2 is a prefabricated part whose specific structure is changed according to the shape of the seat, so that the pressure plate 2 is tightly attached to the seat, thereby avoiding a height difference between the seat and the pressure plate 2. When the rider rides, the thighs are directly pressed on the surface of the support side plate 3. At this time, the air flowing on the surface of the air guide slope 8 passes through the bottom of the support side plate 3, thereby reducing the heat generated in the thighs.

[0023] In the event of a collision, the rider slides forward due to inertia and makes contact with the sponge contact block 6 before his body hits the fuel tank. The sponge contact block 6, together with the silicone baffle 7 and the support spring 10, alleviates the impact stress on the rider and reduces the risk of injury. In cold weather, the support side plate 3 can be removed and the pressure plate 2 can be flipped up to keep it vertical using the silicone suction cup 12, thereby further shielding the body parts facing the fuel tank. The increased contact area between the elastic pressure plate 2 and the body, combined with the properties of the silicone suction cup 12, can also alleviate the impact force of the collision.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
