Problems solved by technology

[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

Embodiment Construction

[0030] Such as figure 1 - Figure 7 The three-dimensional deformable multifunctional electric wheelchair shown includes a movable triangular support relationship consisting of a front wheel 19, a frame, a seat 32, and a rear axle 18. The hydraulic drive unit (in the figure) Not shown) The length of the piston rod 3 that controls the distance between the front wheel 19, the frame, the seat 32 and the rear axle 18, changes the geometric relationship between the front wheel 19, the frame, the seat 32 and the rear axle 18, In order to achieve the control of the width and length of the frame and the height of the seat 32; the retractable triangular structure frame, the seat 32, the front wheels 19, the rear wheels 20, the steering control mechanism, Drive device, speed control mechanism, brake mechanism and lighting warning device; the front end of the telescopic triangle structure frame is connected with two front wheels 19 with adjustable track, and the rear end is connected with a...

Abstract

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, in particular to a vehicle body built on the basis of a triangular structure, the length and width of the vehicle body can be stretched, the height of the seat can be adjusted up and down, and the body can be closed. A multifunctional electric wheelchair for the elderly and the disabled. Background technique [0002] Although the existing electric wheelchair can solve the manpower to push the wheelchair to a certain extent, this kind of wheelchair has high requirements on the quality of the road surface, the outdoor running speed is not high, and it is easy to tilt forward and roll over, and the wheelbase and wheelbase are not adjustable. In particular, the height of the seat is fixed, which greatly limits the use range of the wheelchair and the user's activity space. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a stable, reliable, con...
