Purpose；On the other hand, the locking level 6 is unlocked by the lock pin 7, and the seat board 3, swing rod 4, electric pushrod 5 can be made
And a variable quadrangle is formed between the locking level 6, to make described when not driven by the electric pushrod 5
Seat board 3 is movable, and then realizes that the entire wheelchair folding rack 100 of manual actuation carries out folding, realizes the purpose of hand foldable.
Please refer to Fig. 1 and Fig. 2 again, the wheelchair folding rack 100 further includes backboard 8 and handrail 9, under the backboard 8
End and the rear end of the seat board 3 are pivotally connected.The middle part of one end of the handrail 9 and the backboard 8 is pivotally connected, the handrail 9 it is another
End is pivotally connected with the rear foot 2, and the pivoting point of formation is overlapped with pivoting point A.By by the handrail 9 and the backboard 8 and described
The rear foot 2 is pivotally connected, and can make the backboard 8 and the handrail 9 synchronous expansion when folding is unfolded in the wheelchair folding rack 100
Or folding, it is multiple without using person, it is easy to operate, it is easy to use.
Fig. 1 and Fig. 2 is please referred to again, and the wheelchair folding rack 100 further includes auxiliary stand 10, and the auxiliary stand 10 is set
It is placed between the front foot 1 and the rear foot 2.The auxiliary stand 10 includes that support arm 10a and connecting rod 10b, the upper end of the rear foot 2 are prolonged
Linking arm 22 is stretched out, one end of the support arm 10a and the linking arm 22 are pivotally connected, pivoting point E, one end of the connecting rod 10b
It is pivotally connected with the support arm 10a, pivoting point F, the other end of the connecting rod and the front foot 1 are pivotally connected, pivoting point G.It is described
Auxiliary stand 10 can be opened with the front foot 1 and the movement of the rear foot 2 or folding.
In summary, and Fig. 5 and Fig. 6 is combined, the working principle of wheelchair folding rack 100 of the present invention is carried out below detailed
Description, as follows:
The present invention has automatic and manual both of which:
When automatic mode, the card division 61 of the locking level 6 is stuck in the crossbeam 31 of 3 bottom of seat board, 7 grafting of lock pin
In on the pedestal 32 and pressing on the locking level 6, relatively fixed with the locking level 6 and the seat board 3.Work as folding
When, start the electric pushrod 5, the output end of the electric pushrod 5 is shunk, and the output end of the electric pushrod 5 passes through described
Locking level 6 drives the seat board 3, translates the seat board 3 backward, and the front foot 1 is close to the rear foot 2；Meanwhile the axis
Pin 41 slides on the supporting part 21 and is detached from the supporting part 21；At this moment, the swing rod 4 rotates, and drives the seat board 3
It swings, 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 foot 1 and folding.After the electric pushrod 5 is shunk completely, the front foot 1 is completely close to the rear foot 2, at this moment, institute
It states seat board 3, the backboard 8 and the handrail 9 and also mutually draws close realization 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
The output end of dynamic push rod 5, the electric pushrod 5 stretches out, thus 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 is unfolded, the backboard 8, the handrail
9 and the auxiliary stand 10 be 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.
When manual mode, the lock pin 7 is first separated into the pedestal 32, the lock pin 7 is made to be detached from the locking level 6, this
When, the card division 61 of the locking level 6 still with 31 clamping of crossbeam.When folding, the seat board 3 is pushed manually, makes the seat
Plate 3 translates backward, and the crossbeam 31 is detached from the clamping with the card division 61, and the locking level 6 is swung close to the electric pushrod
5, the pivot pin 41 slides on the supporting part 21 and is detached from the supporting part 21, and at this moment, the swing rod 4 rotates, and drives
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 is shunk 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 also mutually draw close realization folding, and the auxiliary stand 10 is also complete
Full folding.At this point, the wheelchair folding rack 100 is the state in complete folding.When deployment is desired, make the seat 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 is unfolded, and the backboard 8, the handrail 9 and the auxiliary stand 10 are also followed by expansion.At this moment,
The lock pin 7 with 61 clamping of card division, then, then is plugged on the pedestal 32 manually again, makes institute by the crossbeam 31
Lock pin 7 is stated to press on the side of the locking level 6 and fix the locking level 6；The wheelchair folding rack 100 is then in complete
The state be unfolded and locked.
In addition, wheelchair folding rack 100 of the present invention can also first carry out automatic folding, then expansion manually, or first carry out
The operation of manual folding Automatic-expanding again.It needs only assure that before being automatically brought into operation, the lock pin 7 is inserted in into the pedestal 32 to lock
The fixed locking level 6；And before manual operation, the lock pin 7 is separated into the pedestal 32 to unlock the locking level 6.
Since 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 to be 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 arranged, and the lower end of the swing rod 4 and the rear foot 2 are pivotally connected, and described
The upper end of swing rod 4 and the rear end of the seat board 3 are pivotally connected, so as to form a deformable bracket, so that entire wheelchair folding
The folded realization of bracket 100 can folding or expansion；Also, by one electric pushrod 5 of setting, locking level 6 and lock pin 7, when the lock pin 7
When to the locking level 6 locking, it can use the electric pushrod 5 and carry out automatic folding or expansion, record the lock pin 7 to described
When locking level 6 unlocks, manual folding or expansion can be carried out, to achieve the effect that manually or automatically integrally to operate；It is entire to receive
Each bar piece linkage carries out during folding or expansion, folds simply, and use is very convenient, has and is used using handicapped people.
The above disclosure is only a preferred example of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, still falls within the range that the present invention is covered.
