Embodiment Construction

[0098] refer to Figures 1 to 3 , the first embodiment of the electric vehicle of the present invention comprises a vehicle frame 1, a seat 7, a foot rest 8, a drive box 2, an auxiliary machine box 3, a rear rocker arm 4, a front wheel 51, a rear wheel 52, and a driving mechanism 6. Wherein, in this first embodiment, the lowest point of the auxiliary machine box 3 is not higher than the height of the top surface of the drive box 2, so it can avoid affecting the whole vehicle if the auxiliary machine box 3 is set too high. The problem of center of gravity.

[0099] In this first embodiment, the vehicle frame 1 includes a head tube 11, a main tube 12 extending downward from the head tube 11, two side tubes 13 extending backward from the left and right sides of the main tube 12, and a A closed tube 14 between the side tubes 13. Wherein, each side pipe 13 has a footrest pipe part 131, a riser pipe part 132 extending upward from the rear end of the footrest pipe part 131, and a ...

Abstract

The invention provides an electric vehicle. The electric vehicle comprises a frame; the driving box body is mounted on the frame and comprises a driving motor; and the auxiliary engine box body comprises a gear shifting motor, is arranged on the frame at an interval with the driving box body, and is positioned in front of the driving box body.

Description

technical field [0001] The present invention relates to a motorcycle, in particular to an electric motorcycle. Background technique [0002] Common electric motorcycles currently on the market usually use a centrifugal clutch or manually switch gears. Taking an electric motorcycle with two gear switching requirements as an example, if there is a precise gear shifting requirement, a gear shifting motor is required to perform the switching action. If the gear is only shifted by hand, the timing of the gear shift will be imprecise. On the contrary, if the centrifugal clutch is used to shift gears, energy will be lost. Furthermore, the installation of the shift motor needs to consider configuration issues, and more consideration should be given to maintainability and body weight. [0003] China Taiwan Patent No. I593573 discloses an electric motorcycle structure for improving motor efficiency. The instruction manual and the first figure of this Chinese Taiwan No. I593573 anno...
