The present commonly used personal transportation means generally includes an automobile and a motorcycle, and the motorcycle type transportation means is a two-wheel, three-wheel or four-wheel vehicle which is driven by an engine and mainly uses a handle to operate the direction, and the vehicle is the most commonly used transportation means at present due to the characteristics of simple operation, convenient action and low price.
Due to the environmental protection, the electric motorcycle using the motor as the power source is gradually favored by consumers. Generally, in a two-wheeled motorcycle, the ratio of the weight of the motorcycle itself borne by the front and rear wheels has a great influence on the steering feeling of the rider during riding.
In the conventional driving device configuration of the electric motorcycle, in order to arrange the entire weight of the frame on a horizontal reference plane close to the ground, the driving device configuration can improve the stability of the vehicle in the vertical direction when the vehicle travels.

In this arrangement, the motor shaft 121, the output shaft 122 and the rear wheel shaft 131 are arranged almost in a straight line, the output shaft 122 is located in front of the motor shaft 121, the output shaft 122 is coaxial with the frame/rocker 14 pivot, and the arrangement results in an excessively long wheelbase (distance between the front wheel and the rear wheel). Furthermore, because the installation state of the rocker 14 is close to horizontal, the rear horizontal displacement is easy to increase when the rear shock absorber is loaded and stressed, so that the change of the wheel base is overlarge, and the controllability of the electric motorcycle is influenced by a longer vehicle body.
Further, in the electric motorcycle 10, it is generally known that the motor 12 and the battery tube 15 are arranged offset in the front-rear direction, and although the problem of the battery tube 15 being provided in a space below the seat cushion is solved, the disadvantages of the vehicle axle base being lengthened and the space of the foot board being compressed are also caused.
Therefore, how to solve the problems of excessive horizontal displacement of the rear wheel, overlong wheelbase of the whole electric motorcycle, compressed pedal space and the like in the prior electric motorcycle is always a problem faced by the technical personnel in the field.

The electric motorcycle 200 further includes a front wheel 240 and a rear wheel 250, and the front wheel 240 and the rear wheel 250 are respectively mounted on the frame 210. The lower frame of the frame 210 is located between the front wheel 240 and the rear wheel 250. The electric motorcycle 200 also includes a rear cushion 260, a swing arm 270 and a seat 280 connected to the frame 210. In the embodiment of the present invention, the battery accommodating box 220 is disposed below the seat cushion 280 of the electric motorcycle 200, the electric motorcycle 200 includes a pedal 211, the battery accommodating box 220 is disposed between the seat cushion 280 and the pedal 211, and the bottom of the battery accommodating box 220 is disposed on the frame 210 via a bracket 212.
The motor 230 is disposed below the battery accommodating box 220, the motor shaft 231 of the motor 230 transmits power to an output shaft 232, the output shaft 232 transmits power to a rear wheel shaft 251 through a transmission element 233, and the rear wheel shaft 251 drives the rear wheel 250 to rotate, so that the electric motorcycle 200 runs. In practice, the transmission element 233 is a chain, the output shaft 232 is a sprocket shaft, and the motor shaft 231 is disposed within a downward projection range of the battery accommodating box 220 when viewed from a side view of the electric motorcycle 200.
In the embodiment shown in fig. 2 and 3, the frame 210 is connected to the pivot hole 272 of the swing arm 270 through a pivot shaft 271, the pivot shaft 271 is coaxial with the output shaft 232, and the other end of the swing arm 270 is connected to the rear axle 251. The motor shaft 231 is located in front of the output shaft 232, the output shaft 232 is located between the motor shaft 231 and the rear axle 251, and the horizontal position L2 of the output shaft 232 is higher than the horizontal position L1 of the rear axle 251. Therefore, in the embodiment, a connection line between the output shaft 232 and the rear wheel axle 251 forms an included angle θ 1 with a horizontal line (L1 or L2), and the included angle θ 1 is between 5 ° and 25 °. The rear shock absorber 260 is also pivotally connected to the swing arm 270 near the rear wheel 250, and one end of the rear shock absorber 260 is pivotally connected to the frame 210 for shock absorption of the electric motorcycle 200.

The distance from the center point of the front wheel 240 to the center point of the rear wheel 250, i.e., the distance between the front wheel axle 241 and the rear wheel axle 251, is referred to as the wheel base W1. The overall configuration of the invention minimizes the horizontal displacement change of the rear wheel 250 and the change of the wheel base W1, thus being beneficial to reducing the front and rear displacement change of the center of gravity of the whole motorcycle and improving the controllability of the electric motorcycle 200
In the embodiment of the present application, the horizontal position L2 of the output shaft 232 is higher than the horizontal position L3 of the motor shaft 231, and a connection line between the motor shaft 231 and the output shaft 232 forms an angle θ 2 with a horizontal line (L2 or L3). The included angle θ 2 is mainly determined so that the highest point of the casing of the motor 230 does not interfere with the wiring of the battery accommodating box 220 above, for example, when the two-stage transmission clutch is coaxial with the motor shaft 231, which is more serious, so that the connecting line between the motor shaft 231 and the output shaft 232 forms an included angle θ 2 with the horizontal line (L2 or L3).
Therefore, when the motor shaft 231 is disposed below the battery accommodating box 220, the entire axle distance W1 of the electric motorcycle 200 is minimized because the connection line between the output shaft 232 and the rear axle 251 forms an included angle θ 1 with the horizontal line (L1 or L2), and the connection line between the motor shaft 231 and the output shaft 232 forms an included angle θ 2 with the horizontal line (L2 or L3). And the space below the battery accommodating box can be effectively utilized, the height of the seat cushion 280 is reduced, enough space for the pedal 211 is reserved, and the length of the pedal 211 is ensured to be maximized.

The electric motorcycle 200 generally generates an electric signal by turning a throttle handle, and the motor controller 290 drives and controls the motor 230 according to the electric signal, thereby making the electric motorcycle 200 travel and controlling the traveling speed of the electric motorcycle 200. And the motor controller 290 is disposed between the battery receiving box 220 and the rear cushion 260 of the electric motorcycle 200, so that the motor controller 290 and the motor 230 of the present embodiment are disposed at the periphery of the battery connecting unit of the battery receiving module of the battery receiving box 220, thereby shortening the length of the related wiring, and reducing the loss of electric signals and/or electric power in power due to the length of the wiring.
Through the configuration of the driving device, the horizontal position of the output shaft is higher than that of the rear wheel shaft, and the connecting line from the output shaft to the rear wheel shaft forms an included angle with the horizontal line, so that the horizontal displacement change of the rear wheel is reduced, the change of the wheel base is reduced, the front and rear displacement of the gravity center of the whole motorcycle is reduced, and the controllability of the electric motorcycle is improved. The horizontal position of the output shaft is higher than that of the motor shaft, and the connecting line between the motor shaft and the output shaft forms an included angle with the horizontal line.
