The invention aims to provide a novel vehicle, and particularly relates to an electric wheelchair entire system of which the vehicle body of a tripod structure is telescopic in length, width and height, the seat is adjustable in height and the vehicle frame is adjustable on all sides. The three-dimensional transformable multifunctional electric wheelchair has low-gravity-center and low-wind-resistance properties during medium-speed running, and a stable feature after the vehicle frame chassis is stretched, as well as the characteristics that compactness and portability are realized, the vehicle body is small in turning radius and the wheel tread and the wheel space can be telescopic synchronously. The electric wheelchair can contract and deform to have the same horizontal width as a common wheelchair to run at a low speed and stretch and deform to run at a medium speed to realize seamless joint of indoor and outdoor running in specific environments (such as slow running, stopping, elevator entering and running in narrow rooms and roads).
Description
technical field [0001] The invention relates to a vehicle, especially a new electric wheelchair complete vehicle system with a car body built on the basis of a triangular structure, the length and width of the car body are scalable, the height of the seat can be adjusted up and down, and the car body can be closed. The utility model relates to a multifunctional electric wheelchair for the elderly and the disabled. Background technique [0002] Although the existing electric wheelchairs can solve the manpower of pushing wheelchairs to a certain extent, such wheelchairs have high requirements on the quality of the road surface, the outdoor driving speed is not high and they are easy to lean forward and roll over, and the wheelbase and wheelbase cannot be adjusted. , especially the height of the seat is fixed, which greatly limits the scope of use of this wheelchair and the user's activity space. Contents of the invention [0003] The purpose of the present invention is to o...
