Abstract

A chassis device of an electric wheelchair includes a frame unit, a linking unit, a wheel unit and a power unit. The frame unit is provided with a first arrangement of a bottom border which is provided with a first pin joint point, a second arrangement of a standing post which is provided with a second pin joint point and the second arrangement of the standing post of a third pin joint point. The linking unit is provided with two connecting rod groups, which are respectively arranged at two sides of the frame unit. The first connecting rod group is provided with an upper rocker which is articulated at the third pin joint point and extends forwards and backwards, a lower rocker which is articulated at the second pin joint point and extends forwards, a bottom rod which is articulated at the first pin joint point and extends backwards and a back rod which is articulated with the upper rocker and the bottom rod. The bottom rod and the back rod are used to absorb the oblique angle of the rod, which is caused by the up and down swing to bring comfort to the sitting person.

Description

【Technical field】 [0001] The invention relates to a chassis device of an electric wheelchair, in particular to a chassis device of the electric wheelchair which can reduce the swing range when the wheelchair crosses obstacles and make the occupant feel comfortable. 【Background technique】 [0002] For people with leg muscle injuries, elderly people with bifunctional degeneration, physical disabilities, or chronic patients who cannot move independently with their feet, they can choose an electronic wheelchair as a walking aid in daily life appliance. [0003] Since the general road surface has obstacles such as ups and downs and bumps, such as stairs, or raised road surfaces, it is better for the electric wheelchair to have the ability to cross the above obstacles. [0004] As shown in Figures 1 and 2, the chassis device 10 of a conventional electric wheelchair is US Patent No. 7,040,429 "Wheelchair suspension", which is designed to overcome the aforementioned obstacles. The...
