Description
This utility model relates to electric wheelchair, particularly a kind of can comprehensive mobile three-wheel electric wheelchair.
As everyone knows, two drivewheels and two directive wheels that main arm-chair of existing electric wheelchair bottom is provided with are realized displacements, and wherein two drivewheels are as driving usefulness, two directive wheel controlling parties to.Electric wheelchair moves the shortcoming of effort owing to install power set additional thereby overcome manual wheelchair, welcomes and obtain user.But existing electric wheelchair can only along its lead before and after crop rotation translational motion and about turn to, can not laterally move and make no radius and turn to inconvenient user use in the original place.In view of this, but the applicant once disclosed the electric wheelchair that a kind of name is called omnibearing ambulation, this electric wheelchair decapacitation realize fore-and-aft direction move with divertical motion outside, can also make transverse moving left and right and the original place does not have radius revolution, and the stack of carrying out above-mentioned motion is to realize comprehensive displacement in the plane.But because of it takes four-wheel drive, structure is complicated, and the cost height is unfavorable for penetration and promotion.
But the purpose of this utility model provides a kind of three-wheel electric wheelchair of omnibearing ambulation, and it is simpler with respect to the background technology structure, and volume is littler, and it is more steady, more economical to move.
This utility model purpose is achieved through the following technical solutions.
But a kind of three-wheel electric wheelchair of omnibearing ambulation, constitute by chair mechanism, electric control gear, walking mechanism, above-mentioned electric control gear is by power supply, the stick of comprehensive control and electric cabinet are formed, and above-mentioned walking mechanism comprises frame, the chair wheel, driving device, the chair wheel that it is characterized in that chair mechanism is to be made of three combined wheels, and three combined wheels are driving wheel, and the axes intersect of three combined wheels is
Type or be
Type is distributed with a plurality of rollers on the wheel rim of three combined wheels, these a plurality of rollers all can along its separately mandrel freely rotate, three combined wheels are by being bolted to the lateral surface of frame.
When front-wheel was two in such scheme, its axis was the 60-90 degree with direction of advance angle of cut β respectively.
When front-wheel was two in such scheme, angle α was the 0-90 degree between the wheel axis of the wire mandrel of the roller on two front-wheels and the chair of its composition wheel, and two-wheeled angle α equal and opposite in direction, and direction is opposite.Angle is 90 degree between the axis direction of the roller bearing pin on the trailing wheel and the axle axis direction.
The shape of roller can be spindle, half spindle, taper type or other similar shapes in such scheme, and roller can be single distribution along wheel rim, also can doublely distribute, and taking turns its external envelope face by the chair that roller constituted is a face of cylinder.
Compared with prior art, this utility model characteristics are to adopt three wheel drive, and mechanism is simple than the four-wheel wheelchair, and volume is littler, and vibrate little, the safety and steady more that moves, the ratio of performance to price is better.Be particularly suitable for handicapped person such as old people, people with disability and in narrow and small places such as dwelling house, office, market, supermarket, hotel, hospital, use, also can be used as senior office and use with chair, noble furniture and leisure chaise longue.
