Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in invention, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective exploded view of the anti-embodiment for turning over type electric wheelchair of preceding folding of the present invention；
Fig. 2, which is that the preceding folding of the present invention is anti-, turns over the view after type electric wheelchair folds.
Embodiment
The present invention is described in detail for shown each embodiment below in conjunction with the accompanying drawings, but it should explanation, these
Embodiment is not limitation of the present invention, those of ordinary skill in the art according to these embodiment institute work energy, method,
Or equivalent transformation or replacement in structure, belong within protection scope of the present invention.
As shown in figure 1, the preceding folding of the present invention prevents that turning over type electric wheelchair 100 includes：Wheelchair frame, armrest system, locking
Component, storage bag and anti-translation frame 50.
The anti-translation frame 50 is used to place translating into for electric wheelchair, and it specifically includes anti-translation frame body 51 and is arranged at
The auxiliary wheel 52 of the anti-translation frame body both sides.Wherein, pan and the lower backrest 12 before described anti-translation frame body 51
Lower hinge hole is attached, and forms the first linkage structure.The auxiliary wheel 52 of the both sides, can be with when electric wheelchair is run
Ground contacts, the operation of auxiliary electric wheelchair.Meanwhile auxiliary wheel 52 increases the contact area on electric wheelchair and ground, makes
Obtain the more stable of electric wheelchair operation.
As shown in Fig. 2 in addition, during the electric wheelchair folding, the anti-translation frame 50 has folding direction forward.So
Set, after electric wheelchair folding, anti-translation frame 50 will not automatically open up, so as to have more preferable security.
The anti-agent structure for turning over type electric wheelchair of folding before the wheelchair frame is formed.The wheelchair frame includes：On lean on
The back of the body 11, lower backrest 12, seat frame 13, front frame 14 and Rear frame 15.
Wherein, the upper backrest 11 and the lower hinge connection of backrest 12, the lower upper hinge hole of backrest 12 and seat frame
Pan is connected after 13, and pan is connected with pan after the Rear frame 15 in the lower backrest 12, the lower lower hinge of backrest 12
Hole is connected with pan after the Rear frame 15, and pan and the preceding pan of the seat frame 13 connect before the Rear frame 15
Connect, the upper hinge hole of front frame 14 is connected with pan before the Rear frame 15.So as to the Rear frame in the wheelchair frame
15th, seat frame 13 and lower backrest 12 form the second linkage structure.In addition, the storage bag 40 is arranged at the seat frame 13

Between upper backrest 11 and lower backrest 12.So as to, when electric wheelchair deploys, backrest 11 and lower backrest on the available buffer of damping spring 83
Active force between 12, electric wheelchair is both protected, while add comfort level when user uses.In addition, rolled over before described
Formula prevents that turning over type electric wheelchair also includes seat back cushion, and the seat back cushion is installed on the seat frame 13 and upper backrest 11.
The preceding folding prevents that turning over type electric wheelchair 100 also includes：Battery 71, battery case 72 and battery carrier 73.The battery
71 be the anti-power for turning over the operation of type electric wheelchair of preceding folding, and the battery 71 and battery case 72 are fixed in the battery carrier 73,
The battery carrier 73 is positioned at the lower section of seat frame 13, and pan enters with the lower hinge hole of front frame 14 before the battery carrier
Row is connected, and pan is attached with the lower upper hinge hole of backrest 12 after the battery carrier 73.So as to, the front frame 14,
One Rear frame 15, lower backrest 12, battery carrier, formation quadric chain.
In addition, the upper hinge hole of gas spring 60 is connected with pan after the battery carrier 73, described 60 times hinges of gas spring
Chain hole is connected with pan after the anti-translation frame 50, so as to the lower backrest 12, anti-translation frame 50, gas spring 60, the shape of battery carrier 73
Into the 3rd linkage structure.First linkage structure, the second linkage structure, quadric chain and the 3rd linkage structure can be
Linkage is formed when electric wheelchair folding or opening, to facilitate the Quick folding and opening of realizing electric wheelchair.
The armrest system includes handrail tube 21, handrail tray 22 and handrail stay tube 23.Wherein, the handrail tray 22
Respectively with the handrail tube 21 and the hinge connection of handrail stay tube 23, the handrail tube 21 and handrail stay tube 23 simultaneously respectively with it is described
Upper backrest 11 and the hinge connection of seat frame 13.So as to which armrest system can also carry out folding.
Further, the preceding folding prevents that turning over type electric wheelchair 100 also includes：Front-wheel 91, trailing wheel 92 and motor 93,
Wherein, the front-wheel 91 is realized by front fork 94 and the connection of the front frame 14, the trailing wheel 92 enter with the Rear frame 15
Row connection, the motor 93 are that the trailing wheel 92 provides driving force.The trailing wheel 92 is used as driving wheel, while the diameter of trailing wheel 92
More than front-wheel 91.In addition, the preceding folding prevents that turning over type electric wheelchair 100 also includes mud guard 95, the mud guard 95 is located at institute
The top of trailing wheel 92 is stated, and is connected with the lower backrest 12.The motor 93 is electrically connected with battery 71 simultaneously, described
