Abstract

The invention discloses a manned electric cart capable of going up and down stairs. The cart comprises a main box body, a lifting device, an auxiliary supporting device, a walking and braking device and a safe device, wherein a first motor is fixed on a baseplate of the main box body, and an output end of the first motor drives a slide main beam to move along two guiderails by a worm wheel-worm transmission mechanism and a chain wheel-chain transmission mechanism successively. The lifting device comprises two sets of lifting leg components with a same structure, wherein each lifting leg component comprises a base and a second motor and an output end of the second motor drives the main box body to move along a supporting guiderail by a gear transmission mechanism, a spiral rod, a square nutand the slide main beam respectively. The auxiliary supporting device comprises a third motor and an auxiliary leg land supporting rod, wherein an output end of the third motor drives the auxiliary leg land supporting rod to rotate around a connecting rotation shaft by a pair of gears, a screw rod, a movable slide block and an auxiliary leg supporting rod respectively, so that a roller on an endpart of the auxiliary leg land supporting rod can touch the ground. The cart is simple in motion form and stable in motion.

Description

technical field [0001] The invention relates to an electric trolley for carrying people with inconvenient legs and feet up and down steps, in particular to a trolley capable of climbing steps step by step, the climbing process is stable without bumps, and the carrying surface is always parallel to the step surface, which has high safety. By setting the working stroke of the trolley, it can adapt to steps of different sizes. Background technique [0002] Population aging is an important national condition that our country must face directly. As the most populous country in the world, the degree of population aging in my country is deepening day by day, and it has the characteristics of "three supers" of super large scale, super fast speed and heavy burden. According to the latest research on the living conditions of the urban and rural elderly by the National Office on Aging, etc., the main difficulties faced by the contemporary elderly are the increasingly prominent disabili...
