3rd mounting hole, support tube penetrates the 3rd mounting hole and fixed with the first after-poppet plate, and the first after-poppet plate extends back two
Individual stretching plate so that the first after-poppet plate is V-shaped, the rear ends of two stretching plates are provided with trailing wheel, using from support tube conduct
The strong point, and use two stretching plates on the left of backward with rear right side stretching as the mount point of trailing wheel, not only ensure more U.S.
The design effect of sight, and enough spaces, the second after-poppet plate and the 3rd after-poppet plate can be provided for the installation of battery
Positioned at the top for stretching out plate, the 4th after-poppet plate, the 5th after-poppet plate are located at two on the lower section for stretching out plate, the second after-poppet plate
Individual side is separately fixed in the first supporting plate and one of two sides stretched out on plate left side edge, the 3rd after-poppet plate
While being separately fixed in the second supporting plate and another stretching plate right edge, two sides difference on the 4th after-poppet plate
It is fixed on the first supporting plate and one of two sides stretched out on plate left side edge, the 5th after-poppet plate is separately fixed at the
Two supporting plates and another stretching plate right edge, so as to pass through the second after-poppet plate, the 3rd after-poppet plate, the 4th after-poppet
Plate, the 5th after-poppet plate improve the bearing strength and non-deformability of the first after-poppet plate, so as to improve rear wheel support
It is also more attractive in appearance in bearing strength, design.
Propped up preferably, the rear end of two stretching plates is respectively fixed with after the 6th after-poppet plate, the 7th after-poppet plate, the 4th
The rear end of frame plate, the rear end of the 5th after-poppet plate are respectively fixed with the 8th after-poppet plate, the 9th after-poppet plate, the 6th after-poppet plate
On a side, the side respectively with the 8th after-poppet plate of the side on the 7th after-poppet plate, the one of the 9th after-poppet plate
Side is fixed, and the trailing wheel is included after the first universal wheel mechanism and the second universal wheel mechanism, the rear end of the 6th after-poppet plate, the 8th
The rear end of supporting plate is fixed with the first universal wheel mechanism, and the rear end of the 7th after-poppet plate, the 9th after-poppet plate are and the 20000th
To wheel, mechanism is fixed, and the 6th after-poppet plate and the 7th after-poppet plate are inclined to set.Using this structure, by being obliquely installed
Six after-poppet plates and the 7th after-poppet plate can reduce the height of the first universal wheel mechanism and the second universal wheel mechanism, can both adopt
With the smaller universal wheel of wheel footpath, because this electric wheelchair uses front-wheel drive, therefore driving is followed using the less universal wheel of wheel footpath
Rotate to so that turn to more facilitate.
The present invention compared with prior art, with advantages below and effect：, as the strong point, and used using from support tube
The two stretching plates stretched out on the left of backward and on the right side of rear not only ensure design effect more attractive in appearance as the mount point of trailing wheel,
And enough spaces can be provided for the installation of battery, pass through the second after-poppet plate, the 3rd after-poppet plate, the 4th after-poppet
Plate, the 5th after-poppet plate improve the bearing strength and non-deformability of the first after-poppet plate, so as to improve rear wheel support
It is also more attractive in appearance in bearing strength, design.
