Front frame component for foldable double-seat four-wheel electric vehicle

Abstract

The invention relates to a front frame component for a foldable double-seat four-wheel electric vehicle. The front frame component comprises a steering handrail, a rotary handle fixed sleeve, a front wheel frame, a pedal hanging rod, a synchronous connecting rod, an intermediate poke rod, a lateral poke rod, a front wheel bearing support, a front wheel rotating shaft sleeve and a front wheel, wherein an upper lug base and a lower lug base are arranged on the rotary handle fixed sleeve; a vertical rod of the steering handrail is sleeved in the rotary handle fixed sleeve; the lower end of the vertical rod is fixedly connected with the poke rods; the poke rods are fixed on the front wheel bearing support; the other end of each of three poke rods is hinged with the synchronous connecting rod; the pedal hanging rod is fixed on the front wheel frame; a rotating shaft is arranged above the front wheel bearing support and is sleeved in the front wheel rotating shaft sleeve; and the front wheel rotating shaft sleeve is fixed on the front wheel frame. The front frame component is a front frame of the electric vehicle, is a connection foundation of a rear connecting frame, an expansion rod and a pedal and is a key component for the foldable double-seat four-wheel electric vehicle, can meet the requirements that the four-wheel electric vehicle enters an elevator and is folded for collection, and is particularly suitable to be used by old couples and disabled people.

Description

technical field [0001] The invention relates to a foldable four-wheel electric vehicle, in particular to a front frame component of the foldable four-wheel electric vehicle. Background technique [0002] With the increase of the elderly population in the society, the problem of social aging has become more and more prominent, and the travel problems of the elderly and the disabled have not been well resolved. Although electric tricycles or three-wheeled electric disabled vehicles have been developed for them, these models are all evolved from human-powered tricycles. The front frame of this type of electric tricycle is an old-fashioned hurdle type, and the hands and feet of the elderly and disabled people are not normal. Young people are so flexible that it is very inconvenient to get on and off the car. At the same time, the stability of the tricycle is not good. If the steering radius is too small, the steering angle is too large, or the center of gravity of the seat is sh...

Although electric tricycles or three-wheeled electric disabled vehicles have been developed for them, these models are all evolved from human-powered tricycles. The front frame of this type of electric tricycle is an old-fashioned hurdle type, and the hands and feet of the elderly and disabled people are not normal. Young people are so flexible that it is very inconvenient to get on and off the car. At the same time, the stability of the tricycle is not good. If the steering radius is too small, the steering angle is too large, or the center of gravity of the seat is shifted during walking, it is easy to roll over, causing car rollover accident

Existing electric tricycles cannot be folded, occupy a large area and are not convenient for folding and storage, let alone put them in elevators to take them home for storage, and are not suitable for use by urban high-rise residential residents
