Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, in particular to an off-road motorcycle. Background Art

[0002] Off-road motorcycles are popular among young people due to their powerful power and stylish appearance. They are a common off-road tool and offer excellent off-road performance. However, as off-road motorcycles primarily travel on winding mountain roads, these pure rear-wheel drive off-road motorcycles, designed to adapt to more complex and difficult terrain, often fail to meet off-road requirements. Furthermore, rear wheel slippage can make driving difficult when navigating muddy and potholed terrain, reducing off-road performance. There is an urgent need for off-road motorcycles that can address these challenges.

[0003] Chinese patent document CN113022763B discloses an off-road motorcycle that detects whether the vehicle is stationary by using wind resistance during driving, thereby triggering whether the power-assisting part is working. When the vehicle slips or stops, the power-assisting part can increase the friction between the rear wheel and the ground, improve the rear wheel's grip performance, and enhance the off-road motorcycle's passability. At the same time, the kinetic energy is transmitted to the front wheel through the clutch device, achieving two-wheel drive, which has better and stronger adaptability to various terrains.

[0004] The existing technology has the following problems:

[0005] Most of the existing off-road motorcycle exhaust pipes do not have a silencer structure. Instead, they are installed with a silencer. After the silencer is inserted into the muffler connection hole, the large aperture silencer channel is shortened, the silencer space becomes smaller, the exhaust is not smooth, the power performance becomes poor, the effective power is reduced, the noise is loud, and it is difficult to effectively silence the off-road motorcycle exhaust pipe. It is very inconvenient and inflexible to use. Since most of the riding is carried out on complex road sections, the rear wheel will slip when the motorcycle passes through muddy sections and potholes due to insufficient grip. The safety is low and it cannot meet the requirements of off-road And when riding for a long time in hot weather, the buttocks are in close contact with the seat cushion, which is airtight and has a poor heat dissipation effect. However, in order to improve comfort, the surface of the seat cushion is generally made of leather with sponge filled inside, so the heat cannot be effectively discharged, thus affecting the riding experience. At present, riders stand up when riding to separate the buttocks from the seat cushion to dissipate heat, which increases the danger. When riding at night or in dimly lit places, a lighting lamp is usually set on the front side of the motorcycle for lighting. The lighting lamp is generally fixed on the front side of the motorcycle, which is inconvenient to disassemble and assemble. Summary of the Invention

When riding at night or in a dimly lit place, the lighting lamp 32 is used for lighting, which is convenient for riding. When the lighting lamp 32 is damaged and needs to be replaced or repaired, the nut 35 is rotated to remove it from the stud 34, and then the stud 34 is rotated to remove it from the hanging plate 33 and the mounting bracket 31, and the lighting lamp 32 is moved to separate the hanging plate 33 from the mounting bracket 31, and the hanging plate 33 on the new lighting lamp 32 is put on the left side of the mounting bracket 31, and the lighting lamp 32 is installed on the mounting bracket 31 through the engagement between the slot 37 and the block 39, and the stud 34 is rotated to make it threadedly installed with the mounting bracket 31, the block 39, and the hanging plate 33, and then the hanging plate 33 is threadedly installed on the right end of the stud 34 so that its left end is tightly against the right side of the left side of the mounting bracket 31, which is convenient for repairing or replacing the lighting lamp 32.
