The specific embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to this utility model.
Shown in Fig. 1 to 6, the main body of vehicle frame of this lightweight electric wheelchair comprises a back bracket 2, and the both sides of back bracket 2 respectively are provided with a first connecting rod 1; One end and the back bracket 2 of first connecting rod 1 are hinged, and an end of the other end of first connecting rod 1 and second connecting rod 3 is hinged, and the middle part of the other end of second connecting rod 3 and third connecting rod 4 is hinged; One end and the back bracket 2 of third connecting rod 4 are hinged; Vehicle seat 5 is hinged on the first connecting rod 1, and the both sides of vehicle seat 5 form chute 51, and the both sides of back bracket 2 also respectively are provided with a roller 21; Roller 21 is positioned at chute 51, and roller 21 can slide along chute 51.
The lower end that said wheel hub motor is installed in institute's first connecting rod 1 is provided with wheel hub motor 9, and this wheel hub motor 9 is the brushless wheel hub motor, and guide wheel 10 is installed on the third connecting rod.Wheel hub motor 9 drives it through lithium battery and rotates and realize moving around of wheelchair.Rear side at wheel hub motor 9 is equipped with anti-turning wheel 11, can avoid this wheelchair when tilting than wide-angle, to produce rollover through anti-turning wheel 11.Also respectively be provided with a leg guard 8 on two first connecting rods 1, leg guard 8 can form effective protection to the shank of passenger.
Like Fig. 7, shown in 8; The handrail 6 of this lightweight electric wheelchair, backrest 7 and back bracket 2 are hinged through bearing pin 71 successively; Back bracket 2 is provided with alignment pin 72; Be with spring 73 on the alignment pin 72, handrail 6 is provided with and the corresponding pin-and-hole of alignment pin, and it is the inclined-plane that handrail 6 gets faying face with backrest 7 hinged places.When alignment pin 72 passed backrest 7 and is inserted in the pin-and-hole on the handrail 6, handrail 6, backrest 7 and back bracket 2 were in locking state, and this moment, this main body of vehicle frame can not fold.Rotating handrail 6 is the inclined-plane because handrail 6 gets faying face with backrest 7 hinged places, and like this along with the positioning of rotating pin 72 of handrail 6 will be extracted out in pin-and-hole, this moment, main body of vehicle frame can fold.Spring 73 can make alignment pin 72 spring in the pin-and-hole automatically in place.
