Abstract

The utility model discloses a lifting electric wheelchair which comprises a vehicle frame (7), a seat (4), a guiding wheel (11), a driving wheel (3), a motor (2), a controller (1) and a lifting guide post (9), wherein the lifting guide post (9) is fixedly connected between the vehicle frame (7) and the seat (4), a lifting electric push rod (10) which is arranged in parallel with the lifting guide post (9) is arranged between a bottom board of the vehicle frame (7) and the bottom of the seat (4), an electric push rod (5) is connected between a backrest and a cushion of the seat (4), foot supports (8) are arranged on the seat (4), and gas springs (6) are connected between the foot supports (8) and the backrest of the seat (4). After the structure is adopted, the problem that the lifting of the seat (4) and the angle adjustment of the backrest are inconvenient is solved, and the lifting electric wheelchair has the advantages that the structure is simple and compact, the lifting of the seat (4) and the angle adjustment of the backrest save labor and are convenient, and the like.

Description

The lifting electric wheel-chair vehicle

Technical field

This utility model relates to a kind of Wheel-chair of taking turns, the electric wheel-chair vehicle that particularly a kind of disabled person and old people use.

Background technology

Progress along with expanding economy and science and technology, disabled person and old people's living guarantee and quality of life more and more are subjected to the great attention of governments at all levels and various circles of society, the wheel Wheel-chair is as disabled person and old people's special walk instrument, progressively by the common Wheel-chair of taking turns to the electric wheel-chair vehicle transition, make disabled person and old people's activity convenient, range of activity is also increasing, and their quality of life is further enhanced; But also there is weak point in existing electric wheel-chair vehicle: the one, and seat has only the hand-operated lifting function, can only make troubles can for like this part disabled person and old people when adjusting the seat height by manually adjusting the height of seat; The 2nd, the angle adjustment of backrest is used manual recliner more, and operation is effort very, and can not adjust to certain angle easily; Backrest and foot holder be interlock not, when the angle of adjusting backrest as layback or when leaning forward, the position of foot holder immobilizes always, the occupant can not have a very comfortable posture when driving or rest.For this reason, many manufacturers and knowledgeable people develop and manufacture experimently at the problems referred to above, but do not have comparatively ideal product to emerge so far as yet.

Summary of the invention

For overcoming existing electric wheel-chair vehicle above shortcomings, the purpose of this utility model provides a kind of simple and reasonable, seat height and backrest angle lifting electric wheel-chair vehicle easy to adjust.

The technical scheme that its technical problem that solves this utility model adopts, it comprises vehicle frame, seat, directive wheel, driving wheel, motor, controller, lifting guide pillar, the driven by motor driving wheel rolls, the lifting guide pillar is fixedly connected between the base plate and seat bottom of vehicle frame, is provided with the lifting electric pushrod that is arranged side by side with the lifting guide pillar between the base plate of described vehicle frame and the seat bottom.

Backrest angle adjustment for convenience is connected with electric pushrod between the backrest of described seat and the medicated cushion.

In order to make the occupant that a comfortable posture be arranged, described seat is provided with the foot holder, is connected with air spring between the backrest of foot holder and seat.

After adopting said structure, following advantage or effect are arranged compared with the prior art: the one, by the lifting button on the controller, promoting stick again moves forward or backward, make elongation of lifting electric pushrod or contraction, the lifting electric pushrod drives seat and rises or descend, thereby realizes the height adjustment of seat; The 2nd, adjust button by the backrest on the controller, promoting stick again moves forward or backward, make electric pushrod elongation or contraction, and the drive backrest is swung back or is leaned forward, in the backrest deflection, backrest drives foot holder deflection up or down by air spring simultaneously, thereby in the interlock that realizes realizing when backrest angle is adjusted backrest and foot holder.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Shown in Figure 1, specific embodiments for a kind of lifting electric wheel-chair vehicle of this utility model, it comprises vehicle frame 7, seat 4, directive wheel 11, driving wheel 3, motor 2, controller 1, lifting guide pillar 9, motor 2 drives driving wheel 3 and rolls, lifting guide pillar 9 is fixedly connected between the base plate and seat 4 bottoms of vehicle frame 7, is provided with the lifting electric pushrod 10 that is arranged side by side with lifting guide pillar 9 between the base plate of described vehicle frame 7 and seat 4 bottoms.Be connected with electric pushrod 5 between the backrest of described seat 4 and the medicated cushion; Described seat 4 is provided with foot holder 8, is connected with air spring 6 between the backrest of foot holder 8 and seat 4.

When this utility model need be adjusted seat 4 height, the lifting button on the start-up control device 1 at first, the stick that promotes again on the controller 1 moves forward or backward, make 10 elongations of lifting electric pushrod or contraction, seat 4 rises or descends under lifting electric pushrod 10 drives, thereby realizes the height adjustment of seat 4.

When this utility model need be adjusted the backrest angle of seat 4, at first the backrest on the start-up control device 1 is adjusted button, the stick that promotes again on the controller 1 moves forward or backward, make electric pushrod 5 elongations or contraction, the backrest of seat 4 is swung back under the drive of electric pushrod 5 or is leaned forward, thereby in the backrest angle adjustment that realizes seat 4; When the layback of seat 4 backrests or leaning forward, the backrest of seat 4 drives foot holder 8 deflections up or down by air spring 6 again, thereby realizes the interlock of seat 4 backrests and foot holder 8 simultaneously, makes foot holder 8 and seat 4 backrests remain comfortable position.
