[0034] An electric motorcycle is a two-wheeled vehicle powered by electricity, primarily consisting of an electric drive system, frame, wheels, control components, and other auxiliary devices. Currently, the range of an electric motorcycle is limited by its battery capacity, resulting in a limited range that can cause range anxiety for riders, especially during long-distance riding or in areas without convenient charging facilities. When the battery is low, the motorcycle's power performance decreases, making it difficult to maintain a stable speed, causing a significant drop in speed and hindering quick overtaking maneuvers. Climbing hills may also result in slow movement and swaying, which not only greatly affects the rider's travel efficiency but also severely reduces riding comfort and safety.

[0035] Therefore, such as Figures 1 to 4As shown, this utility model discloses a hybrid motorcycle, comprising: a frame 100 and a range extender 300. The frame 100, serving as the basic support structure of the entire vehicle, is welded from high-strength metal materials, possessing excellent rigidity and stability. The frame 100 is equipped with a drive motor, which is a hub motor connected to a power battery 200. The power battery 200 supplies power to the drive motor, which in turn drives the motorcycle. The drive motor receives electrical energy from the power battery 200, thereby driving the motorcycle's wheels and enabling the vehicle to move. The range extender 300 includes an engine and a fuel generator. The range extender 300 is connected to a fuel tank, and both the range extender 300 and the fuel tank are mounted on the frame 100. The engine is equipped with a fuel pump and cylinders. The engine draws fuel from the fuel tank via the fuel pump, burns it in the cylinders, and the resulting heat drives the generator to produce electricity. The range extender 300 has two output terminals, which are electrically connected to the drive motor and the power battery 200, respectively. The range extender 300 can directly power the drive motor to drive the motorcycle, or it can power the power battery 200, ensuring that the power battery 200 has sufficient charge to power the drive motor. This avoids problems such as slow vehicle speed and instability when the motorcycle's battery is low, thus improving the electric motorcycle's range and enhancing driving comfort and safety.

[0036] In some embodiments of this utility model, such as Figure 3 As shown, the hybrid motorcycle also includes a first controller 400. The first controller 400 is electrically connected to the power battery 200, enabling it to monitor the battery's charge, voltage, temperature, and other information in real time, and to rationally allocate the battery's output power. On the other hand, the first controller 400 also controls the operation of the range extender 300. The first controller 400 has preset values; when the charge of the power battery 200 is less than or equal to the preset value, or when the vehicle's power demand exceeds the battery's supply capacity, the first controller 400 controls the range extender 300 to supply power to the power battery 200. The first controller 400 can adjust the power output of the range extender 300 according to actual operating conditions to ensure continuous and stable power output, maintaining stable vehicle operation and range.

[0037] In some embodiments of this utility model (not shown in the figures), the frame 100 includes a handlebar, and the handlebar is equipped with a gear adjustment button. The gear adjustment button's location on the handlebar greatly facilitates user operation. During riding, a simple hand movement on the handlebar is sufficient to easily switch the operating mode of the range extender 300. The gear adjustment button has multiple gears for switching the operating mode of the range extender 300. These multiple gears correspond to different operating modes of the range extender 300, meeting the user's needs in various scenarios and optimizing the ratio of electric energy to fuel consumption, thus achieving efficient energy utilization.

[0038] Furthermore, in some embodiments of this utility model, the multiple gears include a first gear. In the first gear, the vehicle is in fuel priority mode, and the range extender 300 supplies power to the drive motor. The range extender 300 starts working shortly after the vehicle starts, prioritizing power generation through the fuel generator to provide the main power source for the drive motor, while simultaneously charging the power battery 200. This mode is suitable for long-distance travel or high-speed driving scenarios. Continuous and stable power generation ensures that the vehicle avoids insufficient power due to battery depletion during long-term driving, guaranteeing a smooth journey.

[0039] In other embodiments of this utility model, the multiple gears also include a second gear. In the second gear, the vehicle is in intelligent balance mode, and the range extender 300 supplies power to the power battery 200. The range extender 300 intelligently starts or stops working based on the real-time charge level of the power battery 200 and the vehicle's driving power requirements. In some application scenarios, when the charge level of the power battery 200 is less than or equal to a preset value, or when the vehicle's driving power requirements are high, such as during acceleration or hill climbing, the range extender 300 automatically starts generating electricity. Part of the electrical energy is used to drive the motor to maintain vehicle power, and part is used to charge the power battery 200. When the vehicle is traveling at a constant speed and the battery charge is relatively stable, the range extender 300 stops working and continues to rely on the battery for power, so as to achieve rational utilization of fuel and electrical energy, maximizing energy efficiency and economy while ensuring power.

[0040] In other embodiments of this invention, the multiple gears also include a third gear. In the third gear, the vehicle is in pure electric priority mode, and the power battery 200 has a relatively sufficient charge, i.e., higher than a preset value. The range extender 300 will not start working, and the vehicle relies on the power battery 200 to power the drive motor. This enables a zero-emission pure electric riding experience and reduces energy consumption.

[0041] In other embodiments of this invention, the multiple gears also include a fourth gear. In the fourth gear, the vehicle is in extreme mode, and the range extender 300 operates with minimal energy consumption. It only activates when the battery charge drops to a low level, such as 20% of its own charge, and the vehicle requires continuous power. The range extender 300 generates electricity at just the minimum driving power required by the vehicle, maximizing fuel savings. This is suitable for special situations where the vehicle's battery is extremely low and there are no nearby charging or refueling facilities, requiring the vehicle to reach its destination in the most energy-efficient way.

[0042] In some embodiments of this utility model, such as Figure 3As shown, the hybrid motorcycle also includes a battery management system 210, which is electrically connected to the power battery 200 and the first controller 400. The battery management system 210 detects the charge information of the power battery 200 and transmits this information to the first controller 400. The battery management system 210 can monitor parameters such as voltage, current, and temperature of the battery pack in real time. By analyzing and calculating the collected data, the battery management system 210 can detect and calculate the charge information of the power battery 200. After detecting the charge information, the first controller 400, upon receiving the charge information, can reasonably adjust the operating state of the range extender 300 based on the actual driving conditions of the vehicle, the driver's operating commands, and the real-time status of the battery, thereby ensuring that the hybrid motorcycle is always in the optimal operating state, providing users with a safer, more efficient, and more comfortable riding experience.

[0043] In some embodiments of this utility model, such as Figure 3 As shown, the hybrid motorcycle also includes a detection module connected to the fuel tank. The detection module includes a fuel sensor that detects the fuel level in the tank. The detection module detects the fuel level information and transmits it to the first controller 400. The motorcycle is equipped with an instrument panel, which is an important interface for users to obtain vehicle information. The fuel level signal is also transmitted to the motorcycle's instrument panel to display the fuel level information.

[0044] Furthermore, in some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the range extender 300 is equipped with a second controller 310, which is used to control the start and stop of the range extender 300. When the battery charge is lower than a preset value, the second controller 310 receives a command from the first controller 400 and starts the range extender 300, causing it to begin operation. Conversely, when the battery charge reaches a suitable level or the vehicle is in a state where the range extender 300 is no longer needed, the second controller 310 can promptly stop the range extender 300 from operating. The second controller 310 can also adjust the engine speed and the output power of the fuel generator according to the actual needs of the vehicle, ensuring that the range extender 300 operates as needed and avoiding unnecessary fuel consumption and mechanical wear.

[0045] Specifically, in some embodiments of this invention, the second controller 310 is electrically connected to the detection module. The second controller 310 rationally controls the operation of the range extender 300 based on fuel level information. The second controller 310 adjusts the operating mode of the range extender 300 according to the vehicle's driving needs and battery charge status, charging the power battery 200 and providing power to the vehicle. This achieves optimized control of the range extender 300 and the entire hybrid system, improving the vehicle's energy efficiency and range.

[0046] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the motor is equipped with a third controller 500, which is electrically connected to the first controller 400. The third controller 500 can adjust the voltage and current output to the drive motor, thereby controlling the motor speed and torque, achieving smooth acceleration, deceleration or constant speed driving, and ensuring the safe and stable operation of the vehicle in all aspects.

[0047] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the frame 100 includes a front wheel 110, a rear wheel 120, and a connecting frame 130. The front wheel 110 and rear wheel 120 are made of high-strength aluminum alloy and equipped with rubber tires, which can effectively cope with various road conditions. The two ends of the connecting frame 130 are connected to the front wheel 110 and the rear wheel 120 respectively. The front end of the connecting frame 130 is movably connected to the front wheel 110, allowing the front wheel 110 to easily turn left and right. The rear end of the connecting frame 130 is fixedly connected to the rear wheel 120, thereby ensuring that the front wheel 110 and the rear wheel 120 maintain a stable relative position during driving. The range extender 300 and the power battery 200 are set in the connecting frame 130, which effectively utilizes the internal space of the connecting frame 130, making the overall vehicle structure more compact, reducing the space occupied by the range extender 300 and the power battery 200, and improving the space utilization rate of the overall vehicle structure.

[0048] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the connecting frame 130 includes a head tube 131, a lower beam tube 135, a main beam tube 132, a tail rack tube 133, and a rear support tube 134. The head tube 131 is located at the front of the motorcycle, providing frontal support and connection for the frame 100. The main beam tube 132 extends rearward from the head tube 131 to the middle of the frame 100. The tail rack tube 133 is located at the rear of the frame 100 and is mainly used to support the rear components of the motorcycle, such as the rear seat, taillight, and license plate holder. The rear support tube 134 connects to the lower beam tube 135 and extends obliquely rearward to the tail rack tube 133. The rear support tube 134 is inclined towards the rear wheel 120, serving to support and reinforce the rear part of the motorcycle. The lower beam tube 135 is located at the bottom of the frame 100, extending rearward from below the head tube 131 to the middle of the frame 100. The head tube 131, lower beam tube 135, rear support tube 134 and main beam tube 132 together form a trapezoidal structure, which increases the stability of the frame 100.

[0049] In some embodiments of this utility model, such as Figure 1As shown, it can be understood that the rear support tube 134 is also inclinedly equipped with a support frame 140, which is inclined towards the front wheel 110. The support frame 140, the rear support tube 134, and the main beam tube 132 together form a triangular structure to enhance the overall structural stability of the frame 100. It should be noted that a first mounting bracket 150 is connected between the support frame 140 and the rear support tube 134. The first mounting bracket 150 is used to install the third controller 500, effectively utilizing the space between the support frame 140 and the rear support tube 134, making the overall vehicle structure more compact.

[0050] In some embodiments of this utility model, such as Figure 1 As shown, the range extender 300 and the power battery 200 are vertically spaced within the connecting frame 130. The range extender 300 is located at the top of the connecting frame 130, and the power battery 200 is located at the bottom of the connecting frame 130 and mounted on the lower beam tube 135. The lower beam tube 135 also has a laterally extending second mounting bracket 160. One end of the second mounting bracket 160 is fixedly connected to the lower beam tube 135, and the other end is fixedly connected to the support frame 140. The second mounting bracket 160 is used to mount the range extender 300. Mounting the range extender 300 and the power battery 200 inside the connecting frame 130 effectively utilizes the internal space of the connecting frame 130, making the overall vehicle structure more compact, reducing the space occupied by the range extender 300 and the power battery 200, and improving the space utilization rate of the overall vehicle structure. Placing the power battery 200 at the bottom of the connecting frame 130 also lowers the vehicle's center of gravity, which is beneficial for stable vehicle operation.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the range extender 300 and the power battery 200 are vertically spaced within the connecting frame 130. The range extender 300 is located at the bottom of the connecting frame 130 and mounted on the lower beam tube 135, while the power battery 200 is located at the top of the connecting frame 130 and mounted on the second mounting bracket 160. The placement of the range extender 300 and the power battery 200 within the connecting frame 130 effectively utilizes the internal space of the connecting frame 130, resulting in a more compact vehicle structure, reduced space occupied by the range extender 300 and the power battery 200, and improved space utilization of the overall vehicle structure.

[0052] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the power battery 200 is a lead-acid battery, a nickel-metal hydride battery, or a lithium-ion battery. Lead-acid batteries are characterized by low cost and good high-rate discharge performance. At the moment of vehicle start-up, they can quickly output a large current, providing significant power to the drive motor and assisting in a smooth vehicle start. Nickel-metal hydride batteries have good environmental performance and a long cycle life; after multiple charge-discharge cycles, their capacity decays relatively slowly, effectively reducing long-term operating costs. Lithium-ion batteries can store more electrical energy and charge quickly, significantly shortening charging time, saving users time and increasing the vehicle's driving range.

[0053] 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.
