Description

Hybrid vehicles

This creation is about a hybrid vehicle, specifically a two-wheeled or three-wheeled hybrid vehicle.

Currently, motorcycles on the market are mainly divided into gasoline-powered motorcycles and electric motorcycles. While each has its advantages, both also have certain drawbacks, making it difficult to simultaneously meet the requirements of high efficiency and environmental protection. Gasoline-powered motorcycles rely on internal combustion engines for propulsion, offering advantages such as longer range and quick refueling. However, their fuel efficiency is relatively low, and the combustion process produces pollutants such as carbon monoxide (CO) and nitrogen oxides (NOx), impacting the environment and health. Furthermore, internal combustion engines are noisier during operation, affecting riding comfort, and their operation requires regular maintenance, such as changing engine oil, spark plugs, and filters, increasing operating costs. In addition, fluctuations in fuel prices make operating costs unstable, affecting the economic burden on users.

Electric motorcycles, powered by batteries, offer the advantages of zero emissions and low noise. However, their range is still limited by battery capacity, requiring frequent charging for long-distance riding. Charging takes longer than refueling with gasoline, impacting convenience. Furthermore, lithium batteries have a limited lifespan, requiring replacement after prolonged use at a higher cost, increasing the financial burden on consumers. Improper battery recycling after disposal can also pollute the environment, reducing their environmental benefits. Additionally, battery efficiency decreases in low-temperature environments, affecting range and power output. Therefore, both gasoline and electric motorcycles have limitations and cannot simultaneously meet the demands for riding performance and environmental friendliness.

This invention provides a hybrid vehicle to address problems in the prior art, comprising a frame, a hybrid unit, wheels, a battery, a fuel tank, and footrests. The hybrid unit, connected to the frame, includes an internal combustion engine and a motor. The wheels are connected to the hybrid unit, wherein the internal combustion engine and the motor selectively power the wheels. The battery is coupled to the motor and provides it with the electrical power required to drive the wheels. The fuel tank is connected to the internal combustion engine and provides it with the fuel required to drive the wheels. The fuel tank is located below the footrest surface.

In one embodiment, the height of the power battery is greater than the height of the fuel tank.

In one embodiment, the hybrid vehicle further includes a starter motor and a system battery, wherein the starter motor is connected to the hybrid unit and adapted to start the hybrid unit, the system battery is coupled to the starter motor and provides the starter motor with the electrical power required to start the hybrid unit, and the height of the system battery is higher than the height of the fuel tank.

In one embodiment, the hybrid vehicle further includes a seat and a storage compartment, the seat being rotatably connected to the storage compartment and adapted to cover the storage compartment, which is mounted on the vehicle frame.

In one embodiment, the system battery corresponds to the front of the storage box, and the power battery corresponds to the rear of the storage box.

In one embodiment, the frame includes a first extension tube, a second extension tube, a first bridging structure, and a second bridging structure. The first bridging structure bridges the tail end of the first extension tube and the tail end of the second extension tube, and the second bridging structure bridges the first extension tube and the second extension tube. The power battery is disposed on the first bridging structure, and the system battery is disposed on the second bridging structure.

In one embodiment, the frame includes a head tube, a first extension tube, a second extension tube, and a first bridging structure. The first bridging structure bridges the tail ends of the first extension tube and the second extension tube. The head tube is directly or indirectly connected to the first extension tube and the second extension tube. The power battery is disposed on the first bridging structure, and the system battery is disposed on the head tube.

In one embodiment, the frame further includes a fuel tank bracket that spans the first extension tube and the second extension tube, the fuel tank being disposed on the fuel tank bracket and supported by the fuel tank bracket.

In one embodiment, the hybrid vehicle further includes a power line coupled to the power battery and the power motor, wherein the power line extends at least partially along the first extension tube.

In one embodiment, at least a portion of the internal combustion engine is located between the power motor and the fuel tank in a horizontal direction.

In one embodiment, the center of one of the power motor's shafts differs from the center of one of the internal combustion engine's crankshafts.

In one embodiment, the crankshaft center of the power motor is located further rearward than the crankshaft center of the internal combustion engine in the hybrid vehicle.

In one embodiment, on one side of the projection plane, the power motor at least partially overlaps with the wheel.

In one embodiment, the center of the power motor's pivot is located between the center of the crankshaft of the internal combustion engine and the center of the wheel's axle.

This invention's hybrid vehicle combines fuel and electric power sources to improve energy efficiency, reduce emissions, and achieve both long range and environmental benefits, overcoming the shortcomings of existing technologies. In this invention, the fuel tank is placed under the footrests. Because the fuel tank is close to the internal combustion engine, the length of the fuel line between them can be shortened, thereby saving costs and improving reliability. Furthermore, due to the weight of the fuel tank, placing it under the footrests lowers the vehicle's center of gravity, improving riding stability.
