The invention provides an electric tricycle telescopic frame, and relates to the technical field of frames, the electric tricycle telescopic frame comprises a front frame, a rear frame is movably arranged in the front frame, a front seat and a rear seat are respectively arranged on the upper surfaces of the front frame and the rear frame, and a counterweight device is arranged at the lower end of the rear frame. The lower end of the rear frame is further provided with a driving device used for driving the rear frame to stretch out and draw back. The driving device comprises a rack and a pull rope, and the rack is movably arranged at the lower end of the rear frame and used for driving the pull rope; the counterweight device is composed of a counterweight block, and one end of the pull rope is connected with the counterweight block and used for driving the counterweight block and the rear seat to move. The rack in the driving device moves backwards to tighten the pull rope so as to pull the balancing weight in the balancing weight device to slide forwards, the balancing weight slides forwards to enable the whole gravity center of the device to be transferred forwards, and therefore the problem that the gravity center shifts and the frame is unstable after the rear frame is prolonged is automatically solved, and the safety of the frame is improved.
本发明提供一种电动三轮车伸缩车架,涉及车架技术领域,包括前车架,所述前车架内可移动设置有后车架,所述前车架与后车架的上表面分别设置有前座与后座,所述后车架的下端设置有配重装置,所述后车架的下端还设置有驱动装置用于驱动后车架伸缩;所述驱动装置包括齿条以及拉绳,所述齿条可移动设置于后车架下端用于驱动拉绳;所述配重装置为配重块构成,所述拉绳的一端与配重块连接用于驱动配重块以及后座移动。本发明通过驱动装置中的齿条后移会使使拉绳收紧而拉动配重装置中的配重块向前滑动,配重块向前滑动会使本装置的整体重心向前转移,从而自动克服后车架延长后导致的重心偏移车架不稳定的问题,进而提高车架的安全性。
