Problems solved by technology

[0003] However, although the existing electric wheelchairs have a high degree of intelligence, their anti-rollover performance is poor.
Although some electric wheelchairs are also provided with an anti-turnover mechanism, it is often installed on the electric wheel afterwards.
In this way, before the frame is folded, it is necessary to remove the anti-overturn mechanism or adjust the anti-overturn position, so that it cannot be folded or opened quickly, which is inconvenient for use

Abstract

The invention provides a forwards-folded rollover prevention electric wheelchair, which comprises a wheelchair frame, armrest devices, a locking component, a storage bag and a rollover prevention frame, wherein the wheelchair frame comprises an upper backrest, a lower backrest, a seat frame, a front frame and a rear frame; each armrest device comprises an armrest tube, an armrest support block and an armrest support tube; the storage bag is arranged below the seat frame; the rollover prevention frame comprises a rollover prevention frame body and auxiliary rollers are arranged on the two sides of the rollover prevention frame body; a front hinge hole of the rollover prevention frame body is connected with a lower hinge hole of the lower backrest to form a first linkage structure; when the electric wheelchair is folded, the rollover prevention frame is forwards folded. The electric wheelchair is high in safety and convenient to use; the rollover prevention frame is arranged to prevent the electric wheelchair from rollover, and can be linked along with the folding of the electric wheelchair, so that the electric wheelchair is conveniently folded and used; in addition, the forwards-folded rollover prevention electric wheelchair is further provided with the storage bag, so that functions of the electric wheelchair are effectively expanded.

Description

technical field [0001] The invention relates to a wheelchair, in particular to an electric wheelchair with good safety and anti-overturn function. Background technique [0002] The electric wheelchair is based on the traditional manual wheelchair, superimposed with high-performance power drive device, intelligent control device, battery and other components, transformed and upgraded, equipped with artificially operated intelligent controller, which can drive the wheelchair to complete forward, backward, turning, and standing It is a new generation of intelligent wheelchair with multiple functions such as , lying flat, etc. It is a high-tech product combining modern precision machinery, intelligent numerical control, engineering mechanics and other fields. [0003] However, although the existing electric wheelchairs are highly intelligent, their anti-rollover performance is relatively poor. Although some electric wheelchairs are also provided with an anti-turnover mechanism,...
