Detailed description of the invention
Electric wheelchair of the prior art plays seat device only can carry out lift adjustment to the seat of wheelchair, moving horizontally of seat cannot be realized, cause seat cannot carry out having helped according to the gravity center shift adjusting position of human body, or can only rise by one-side driving seat, seat can not be driven to decline, there are problems in using with not enough.
The present invention is directed to deficiency of the prior art, by arranging drive mechanism and seat is hinged fixing, under the drive of driving mechanism, drive mechanism can with itself and the hinged fixing one end of vehicle frame for center of circle circle swing, gradually seat is upwards carried forward in the process swung, play seat process steady, contribute to user and play seat voluntarily and perform physical exercise, reduce rising of user and sit difficulty, make electric wheelchair more humane; And this plays seat mechanism structure simply, be convenient to install and use, cost is lower.
To be clearly and completely described technical scheme of the present invention by detailed description of the invention below.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
Please also refer to Fig. 1 to Fig. 5, Fig. 1 is the front view of wheelchair disclosed by the invention.Fig. 2 is the axonometric chart of wheelchair disclosed by the invention.Fig. 3 is the structural representation that the seat of wheelchair disclosed by the invention rises.Fig. 4 is the axonometric chart of a kind of wheelchair Qi Zuo mechanism disclosed by the invention.Fig. 5 is the left view of a kind of wheelchair Qi Zuo mechanism disclosed by the invention.As shown in the figure, a kind of wheelchair Qi Zuo mechanism, be arranged at and be provided with vehicle frame 1, driving wheel 2, drive motors 3, universal wheel 4 with on the electric wheelchair of seat 5, Qi Zuo mechanism comprises the below that is arranged at seat 5 and drives seat 5 to be elevated and movable driving mechanism 61 and drive mechanism, and driving mechanism is straight-line motion mechanism;
The stiff end of driving mechanism 61 is hinged to be fixed on vehicle frame 1, and free end is hinged to be fixed on seat 5 or drive mechanism; In crank and rocker mechanism between drive mechanism and driving mechanism, rectilinear motion is converted to swing, and the size of the amplitude of oscillation can be regulated according to the collapsing length of driving mechanism.
Drive mechanism comprises the side link 62 being symmetricly set in seat 5 both sides, is parallel to each other between side link 62, and one end of side link 62 is hinged to be fixed on vehicle frame 1, and the other end is hinged to be fixed on seat 5; Being run by driving mechanism linear telescopic makes side link swing around vehicle frame, then drives seat lifting and moves forward and backward.
Every side of seat 5 is provided with two side links 62 be parallel to each other, and forms one group of parallel-crank mechanism between two side links 62 of every side and seat 5, vehicle frame 1.This parallel-crank mechanism under the drive of driving mechanism 61, can swing for the center of circle with the link of side link and vehicle frame, upwards swings and helped, to lower swing homing.
Driving mechanism 61 is electric pushrod.Electric pushrod has that volume is little, precision is high, self-locking property is better and sensitivity comparatively advantages of higher.Wherein, driving mechanism also can be cylinder.
Drive mechanism also comprises the connecting rod 63 of two side links 62 of connected symmetrical dendrimer, and driving mechanism 61 and connecting rod 63 are hinged fixing.By arranging connecting rod, can improve the connective stability between side link 62 on the one hand, on the other hand, driving mechanism 61 can directly act on connecting rod 63 center, only uses a driving mechanism can drive the movement of seat, reduces use cost.
The front end of vehicle frame 1 is also provided with the handrail for aiding upright, and handrail is symmetricly set in the both sides of vehicle frame 1.Handrail comprises the support bar 64 be fixedly installed on vehicle frame 1 and the handle 65 be positioned on support bar 64, and one end of handle 65 is inserted in support bar 64, and handle 65 adopts to be threaded or to sell with support bar 64 and is connected, with the height of adjustable handrail.By handrail scalable being arranged, the user being applicable to different height uses, and the scope of application is wider.
Operation principle of the present invention is as follows:
Electric pushrod starts, in the process that electric pushrod stretches out by the parallel-crank mechanism formed between side link 62 and seat 1 with the link of side link 62 and vehicle frame 1 for the center of circle, upwards forward rocking motion, seat 5 is driven and moves forward and rise, help user to stand, otherwise electric pushrod shrink, parallel-crank mechanism backward to lower swing, seat return.
The extension elongation regulating electric pushrod can be needed to regulate the amplitude of oscillation of parallel-crank mechanism according to client, be applicable to the user demand of different height user.
