Summary, and Fig. 5 and Fig. 6 is combined, the operation principle to wheelchair folding rack 100 of the present invention is carried out in detail below
Description, it is as follows：
The present invention has automatic and manual both of which：
During automatic mode, the card division 61 of the securing rod 6 is stuck in the crossbeam 31 of the bottom of seat board 3, the grafting of lock pin 7
In on the pedestal 32 and pressing on the securing rod 6, relatively fixed with the seat board 3 with the securing rod 6.Work as folding
When, start the electric pushrod 5, the output end of the electric pushrod 5 is shunk, the output end of the electric pushrod 5 passes through described
Securing rod 6 drives the seat board 3, the seat board 3 is translated backward, and the front foot 1 is close to the rear foot 2；Meanwhile, the axle
Pin 41 slides on the supporting part 21 and departs from the supporting part 21；At this moment, the swing rod 4 is rotated, and drives the seat board 3
Swing, the backboard 8 and the handrail 9 also swing simultaneously, in addition, the connecting rod 10b and support arm 10a is also with before described
The swing of pin 1 and folding.After the electric pushrod 5 shrinks completely, the front foot 1 is completely close to the rear foot 2, at this moment, institute
State seat board 3, the backboard 8 and the handrail 9 and also mutually draw close and realize folding, and the also complete folding of the auxiliary stand 10.This
When, the wheelchair folding rack 100 is the state in complete folding.When deployment is desired, it is only necessary to be again started up the electricity
Dynamic push rod 5, the output end of the electric pushrod 5 is stretched out, so that seat board 3 described in pushing tow, the pivot pin 41 of the rear end of the seat board 3 is again
The secondary top for sliding into the supporting part 21, meanwhile, the relatively described rear foot 2 of the front foot 1 deploys, the backboard 8, the handrail
9 and the auxiliary stand 10 also followed by expansion.After the electric pushrod 5 is fully extended, the wheelchair folding rack 100 is then located
In the state being fully deployed.
During manual mode, the lock pin 7 is first separated into the pedestal 32, the lock pin 7 is departed from the securing rod 6, this
When, the card division 61 of the securing rod 6 still with the clamping of crossbeam 31.When folding, the seat board 3 is promoted manually, makes the seat
Plate 3 is translated backward, and the crossbeam 31 departs from the clamping with the card division 61, and the securing rod 6 is swung close to the electric pushrod
5, the pivot pin 41 is slid on the supporting part 21 and departs from the supporting part 21, at this moment, and the swing rod 4 is rotated, and is driven
The seat board 3 is swung, and the backboard 8 and the handrail 9 are also swung simultaneously, in addition, the connecting rod 10b and support arm 10a
The folding with the swing of the front foot 1.After the electric pushrod 5 shrinks completely, the front foot 1 is completely close to the rear foot
2, at this moment, the seat board 3, the backboard 8 and the handrail 9, which are also mutually drawn close, realizes folding, and the auxiliary stand 10 is also complete
Full folding.Now, the wheelchair folding rack 100 is the state in complete folding.When deployment is desired, the seat is made manually
Plate 3 is swung, so that the pivot pin 41 of the rear end of the seat board 3 slides into the top of the supporting part 21 again, it is at the same time, described
The relatively described rear foot 2 of front foot 1 deploys, and the backboard 8, the handrail 9 and the auxiliary stand 10 also followed by expansion.At this moment,
The crossbeam 31 again with the clamping of card division 61, then, then the lock pin 7 is plugged on the pedestal 32 manually, makes institute
Lock pin 7 is stated to press on the side of the securing rod 6 and fix the securing rod 6；The wheelchair folding rack 100 is then in complete
The state deployed and locked.
In addition, wheelchair folding rack 100 of the present invention can also first carry out automatic folding, then expansion, or first carry out manually
The operation of manual folding Automatic-expanding again.Need only assure that before being automatically brought into operation, the lock pin 7 is inserted in the pedestal 32 to lock
The fixed securing rod 6；And before manually operated, the lock pin 7 is separated the pedestal 32 to unlock the securing rod 6.
Because the present invention is by the way that the upper end of the upper end of the front foot 1 and the rear foot 2 is pivotally connected, before the seat board 3
End and the middle part of the front foot 1 are pivotally connected, and a swing rod 4 is set again, the lower end of the swing rod 4 is pivotally connected with the rear foot 2, and described
The upper end of swing rod 4 and the rear end of the seat board 3 are pivotally connected, so as to constitute a deformable support so that whole wheelchair folding
Folded support 100 is realized can folding or expansion；Also, by setting an electric pushrod 5, securing rod 6 and lock pin 7, when the lock pin 7
When being locked to the securing rod 6, it is possible to use the electric pushrod 5 carries out automatic folding or expansion, record described in 7 pairs of the lock pin
When securing rod 6 is unlocked, manual folding or expansion can be carried out, so as to reach the effect of manually or automatically one operation；It is whole to receive
Each bar piece linkage is carried out during folding or expansion, folds simply, using very convenient, have and used using handicapped people.
Above disclosed is only the preferred embodiments of the present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to scope of the present invention patent, still fall within the scope that the present invention is covered.
