Problems solved by technology

However, the existing tricycles are large in volume and are not conducive to placement. Although some foldable tricycles have been designed, these foldable tricycles still have some obvious defects, and the folding effect is not ideal, especially the main beam of the tricycle as the main supporting beam , while ensuring its foldability, how to ensure its safety needs to be improved

Abstract

The invention discloses a folding electric tricycle which comprises an underpan of the tricycle, a main beam, a main beam bracket and a foldable four-bar support. The main beam support is fixed on the underpan of the tricycle, and the main beam and the main beam support are connected through a rotating shaft; the main beam support is provided with stepped holes used for locating and locking an opening of the main beam, and the main support is provided with a through hole matched with the stepped holes; the main beam support is further provided with a clamping jaw used for locking the bottom end of the main beam; the foldable four-bar support comprises four support bars and a saddle supporting plate which form a four-bar structure which can swing in the front-back direction of the tricycle; the saddle supporting plate is provided with two saddle seats which are parallel to each other and are arranged in the front-back direction of the tricycle, and the distance between the saddle seats is larger than the maximum diameter of the main beam, so that the main beam can be downwards placed between the saddle seats when the main beam is folded.

Description

technical field [0001] The invention belongs to the technical field of electric tricycles, in particular to a foldable electric tricycle. Background technique [0002] With the continuous improvement of people's quality of life, the demand for energy saving, environmental protection, portability, diversity, complementarity and aesthetics of vehicles is becoming more and more urgent. As a short-to-medium-distance transportation tool with energy saving, environmental protection, convenient travel and relatively low cost of use, electric vehicles are very popular in urban and rural areas. [0003] Tricycles have good stability and flexible steering, which are very suitable for short-distance travel, especially for the elderly and the disabled. With the arrival of the aging population in our country, the market prospect is very broad. Therefore, based on the above two points, battery tricycles have become especially suitable for the elderly. One of the best means of transportat...
