The invention relates to the technical field of electro-tricycles, and discloses a buffer device for an electro-tricycle carriage. The device comprises a frame main body, the top of the frame main body is provided with a carriage bracket, the outer wall of the carriage bracket is provided with a damping spring, the top of the damping spring is provided with a first sliding assembly, and a carriage body is arranged at the top of the first sliding assembly. According to the buffer device for the electro-tricycle carriage, the up-down impact force between the carriage body and the carriage support is preliminarily absorbed and damped through the damping springs, and then the transverse impact force of the carriage body is converted into the vertical impact force through the first sliding assembly, a second sliding assembly and a third sliding assembly; and the kinetic energy is secondarily absorbed through the damping springs, so that the effect of simple and convenient multi-stage damping is achieved, the situation of unsoldering or breakage caused by too large stress of the carriage due to bumping is avoided, the protection performance of the carriage of the electro-tricycle is improved, and the service life of the carriage of the electro-tricycle is prolonged.

    本发明涉及电动三轮车技术领域,且公开了一种电动三轮车车厢用缓冲装置,包括车架主体,所述车架主体的顶部设置有车厢支架,所述车厢支架的外壁设置有减震弹簧,所述减震弹簧的顶部设置有第一滑动组件,所述第一滑动组件的顶部设置有车厢本体。该电动三轮车车厢用缓冲装置,通过减震弹簧对车厢本体与车厢支架之间的上下冲击力进行初步吸收并减震,再通过第一滑动组件、第二滑动组件和第三滑动组件将车厢本体的横向冲击力转化为竖向冲击力,并通过减震弹簧二次吸收其动能,达到简单方便多级减震的效果,避免车厢因颠簸受力过大而导致脱焊或断裂的情况发生,从而提高了该电动三轮车车厢的防护性能,并延长了该电动三轮车车厢的使用寿命。
