The invention provides an electric vehicle multi-gear speed change mechanism which comprises a vehicle frame, a rear axle gearbox is installed at the bottom of the vehicle frame, a clutch shifting fork and a first differential gear shifting fork are arranged on the rear axle gearbox, a brake handle is arranged at the right end of the vehicle frame and connected with the clutch shifting fork through a clutch inhaul cable, and a second differential gear shifting fork is arranged at the right end of the vehicle frame. A linkage rod is rotationally installed at the bottom of the right end of the frame, a gear shifting pedal coaxially and fixedly installed at one end of the linkage rod is arranged on the frame, a gear shifting pull rod connected with the gear shifting pedal is installed at the bottom of the frame in a left-right sliding mode, and the other end of the gear shifting pull rod is connected with a first differential gear shifting fork. Through cooperative use of a brake handle, a clutch inhaul cable, a clutch shifting fork, a rear axle gearbox, a gear shifting pedal, a linkage rod and a gear shifting pull rod, the speed ratio is adjusted, the multi-gear effect is achieved, and through cooperative use of an elastic plate, an anti-collision plate, a guide rod and an auxiliary spring, the impact force of the anti-collision plate to a protective shell can be reduced.

    本发明提供了一种电动车多档变速机构,包括车架,所述车架的底部安装有后桥变速箱,所述后桥变速箱上设置有离合拨叉和第一差速器变档拨叉,所述车架的右端设置有闸把,所述闸把与离合拨叉通过离合拉索连接,所述车架右端底部转动安装有联动杆,所述车架上设有同轴固定安装在联动杆一端的变档踏板,所述车架的底部左右滑动安装有与变档踏板连接的变档拉杆,所述变档拉杆的另一端与第一差速器变档拨叉连接;通过闸把、离合拉索、离合拨叉、后桥变速箱、变档踏板、联动杆、变档拉杆之间的配合使用,从而实现速度比的调配,达到多档效果,通过弹性板、防撞板、引导杆、辅助弹簧之间的配合使用,这样可以减轻防撞板对防护壳的撞击力度。
