The invention discloses a low-speed sounding alarm device for an electric vehicle, and aims to provide a low-speed sounding alarm device which can not only meet the low-speed sounding alarm function, but also omit a complex alarm system, reduce the development cost, and avoid the influence on the driving experience due to the false operation of sounding alarm in the high-speed driving process of the electric vehicle caused by the fault of the alarm system. The low-speed sounding alarm device for the electric automobile is used for solving the problem. The motor comprises a motor rotating shaft; convex peaks are arranged on the outer wall of the sound steel ring; the knocking device is arranged on the motor rotating shaft and comprises a guide hole extending in the radial direction of the motor rotating shaft, a knocking piece capable of sliding along the guide hole and a spring, and the spring provides elastic force to drive the knocking piece to move towards the outer wall of the sound steel ring; when the speed of the electric automobile is smaller than a set value and the rotating shaft of the motor drives the knocking device to rotate, the knocking piece collides with the convex peak to generate knocking sound.

    本发明公开了一种电动汽车低速发声报警装置,旨在提供一种不仅能够满足低速发声报警功能,而且省去了复杂的报警系统,降低开发成本,并避免因报警系统故障,出现电动汽车高速行驶过程中发出声音报警的误动作,而影响驾驶体验,甚至影响驾驶安全的问题的一种电动汽车低速发声报警装置。它包括:电机转轴;声钢圈,其外壁上设有凸峰;设置在电机转轴上的敲击装置,包括沿电机转轴径向延伸的导向孔、可沿导向孔滑动的敲击件及弹簧,弹簧提供弹性力驱动敲击件朝声钢圈外壁方向移动;当电动汽车的车速小于设定值,电机转轴带动敲击装置转动的过程中,敲击件与凸峰之间碰撞产生敲击声。
