Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycles, in particular to an electric motorcycle frame. Background Technique

[0002] An electric motorcycle is a type of electric vehicle that uses a battery to drive an electric motor. The electric drive and control system consists of a drive motor, a power source, and a speed control device for the motor. Other devices of the electric motorcycle are basically the same as those of an internal combustion engine. It is classified into an electric moped and an electric ordinary motorcycle according to the maximum speed or motor power. The components of an electric motorcycle include: an electric drive and control system, mechanical systems such as a driving force transmission, and a working device for completing a given task. The electric drive and control system is the core of the electric vehicle and the biggest difference from a vehicle driven by an internal combustion engine. Both electric two-wheel mopeds and electric two-wheel ordinary motorcycles belong to motor vehicles.

[0003] When an ordinary motorcycle is in use, when the engine is working, the overall temperature of the vehicle body is relatively high and heat dissipation is difficult. On the one hand, it is easy to cause burns to the rider and passenger. On the other hand, a relatively high temperature is more likely to cause a fire, with a relatively high risk. Moreover, the overall structure of the frame is relatively heavy, and energy is wasted during riding. When an ordinary motorcycle is in use, the seat is fixed to the vehicle body, and only the buffer structure between the wheels and the vehicle body is used for buffering. When bumping, the rider and passenger will still be jolted up, and the damping effect is not ideal.

[0004] Therefore, we propose an electric motorcycle frame to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electric motorcycle frame to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An electric motorcycle frame includes two U-shaped vertical pipes. Multiple connecting pipes are fixedly connected between the two U-shaped vertical pipes. Above the U-shaped vertical pipes, there is a main beam. The lower end of the main beam is fixedly connected to the right arm of the U-shaped vertical pipe. Below the two main beams, there is a same support pipe. The lower end of the support pipe is fixedly connected to both U-shaped vertical pipes. An inclined pipe is fixedly connected inside the U-shaped vertical pipe. The inclined pipe is fixedly connected to the upper end of the left arm of the U-shaped vertical pipe. A head pipe is arranged on the left side of the main beam. The two inclined pipes and the left ends of the two main beams are all fixedly connected to the head pipe. An installation frame is fixedly installed between the two main beams. A tail fork is arranged on the right side of the two U-shaped vertical pipes. A shock absorption mechanism is arranged between the tail fork and the installation frame. The left end of the tail fork is rotatably connected to the two U-shaped vertical pipes. On the upper right side of the two main beams, there is a buffer seat plate. A buffer mechanism for buffering the buffer seat plate is arranged on the two main beams.

[0008] Further, the shock absorption mechanism includes a shock absorption telescopic rod. On both sides of the shock absorption telescopic rod, there are resistance pieces arranged. A buffer spring is sleeved outside the shock absorption telescopic rod. The two ends of the buffer spring are respectively fixedly connected to the two resistance pieces. The two ends of the shock absorption telescopic rod are respectively rotatably connected to the tail fork and the installation frame.

[0009] Further, the buffer mechanism includes a fixed plate fixedly connected to the two main beams. A buffer telescopic rod is rotatably connected to the fixed plate. The end of the buffer telescopic rod far away from the fixed plate is rotatably connected to a cross bar. At both ends of the cross bar, there are first buffer members rotatably connected. One ends of the two first buffer members are respectively rotatably connected to the two main beams. The other ends of the two first buffer members are rotatably connected to the lower right side of the buffer seat plate. On the lower left side of the buffer seat plate, there are two second buffer members rotatably connected. The lower ends of the two second buffer members are respectively rotatably connected to the two main beams.

[0010] Further, a rotating shaft is rotatably connected to the left end of the tail fork. A rotating hole is arranged on the U-shaped vertical pipe. The rotating shaft is rotatably connected to the two rotating holes.

[0011] Further, a charging hole mounting frame is jointly installed at the left ends of the two U-shaped vertical pipes.

[0012] Further, footrests are installed on the opposite sides of the two U-shaped vertical pipes.

[0013] Further, a motor reserved cavity is arranged on the tail fork. Installation grooves are arranged on both arms of the tail fork.

[0014] Compared with the prior art, the beneficial effects of the present utility model are at least as follows:

[0015] 1. By setting the shock absorbing mechanism and the buffer mechanism, when the vehicle body is bumpy, the shock absorbing mechanism can reduce the impact force on the vehicle body. After the shock absorbing mechanism, the vehicle body still has a tendency to vibrate upward. When the vehicle body moves upward, the buffer telescopic rod will be squeezed, and the buffer telescopic rod will buffer the buffer seat plate, further reducing the impact of the vehicle body vibration on the rider, thereby achieving the effect of secondary shock absorption. When riding, the shock absorption effect is better;

[0016] 2. By arranging U-shaped vertical tubes, oblique tubes and main beams, a larger space is formed by welding around the U-shaped vertical tubes, oblique tubes and main beams for placing battery packs, and charging the battery packs through the charging mounting frame. On the one hand, it is battery-powered, generates less heat, and the overall temperature of the vehicle body is low, which will not burn the driver and passengers, and the fire hazard is small. On the other hand, the frame structure is simple and the overall weight is small. When riding, it will not consume much energy, save energy, and will not pollute the environment.

[0017] The utility model can achieve secondary shock absorption, has good shock absorption effect, is simple in structure, saves energy during riding, does not cause pollution to the environment and has little fire hazard. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that a cross plate is connected between the two U-shaped vertical pipes 1, and a support foot mounting block is installed on the cross plate.

[0025] In this embodiment, a mounting bracket 7 is fixedly installed between the two main beams 3. On the right side of the two U-shaped vertical pipes 1 is provided with a tail fork 8. It is worth mentioning that a rotating shaft 20 is rotatably connected to the left end of the tail fork 8. There is a rotating hole 21 on the U-shaped vertical pipe 1. The rotating shaft 20 is rotatably connected to the two rotating holes 21. A damping mechanism 9 is provided between the tail fork 8 and the mounting bracket 7. Specifically, the damping mechanism 9 includes a damping telescopic rod 12. On both sides of the damping telescopic rod 12 are provided with abutting pieces 13.

[0026] In this embodiment, a buffer mechanism 11 for buffering the buffer seat plate 10 is provided on the two main beams 3. It should be noted that the buffer mechanism 11 includes a fixed plate 15 fixedly connected to the two main beams 3.
