Specific implementation mode
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7：A kind of Portable light electric wheel-chair vehicle, it includes
Vehicle frame bottom end rail 1, front fork 4, front-wheel 5, left vehicle frame 12, right vehicle frame 11 are equipped with low steering resistance damping in 1 front of vehicle frame bottom end rail
Fore wheel structure, the low steering resistance damping fore wheel structure is to weld front shaft sleeve 2 in 1 front of vehicle frame bottom end rail, in front shaft sleeve 2
Interior to be equipped with front-wheel shaft 3, which connect with 4 upper end of front fork, 3 top of front-wheel shaft enter front shaft sleeve 2 it is interior according to
Secondary wear is connected to lower punching press shell needle bearing 27, disk spring 26, elastic polyurethane pad 25, thrust ball bearing with flat seat 24, upper punching
Shell needle bearing 23, anti-support catch 22 are pressed, the screw of the fixed anti-support catch 22 of pressing is connected on 3 upper end of front-wheel shaft；
In actual use, the weight of vehicle body and people are transmitted to by vehicle frame bottom end rail 1 on the front shaft sleeve 2 welded therewith, edge
It is axially pressed onto on thrust ball bearing with flat seat 24, then by butterfly spring 26, elastic polyurethane pad 25 bumper and absorbing shock step by step, before being pressed in
It takes turns in shaft 3, ground is applied to by front fork 4, front-wheel 5.Rotation before upper and lower two punching press shells needle bearing 23,27 ensures
3 radial positioning is reliably accurate, and rolling friction can guarantee that its revolution and axial movement are flexible again.22 peace of anticreep catch on top
The axial movement of front-wheel shaft 3 then can be achieved in face thrust ball bearing 24, reduces steering resistance, and complete its axially position.
Using upper and lower punching press shell needle bearing 23,27, that is, keep its small size with sliding bearing, low weight and height
Rigidity, and cooperation precision can be increased substantially and lower frictional force.Meanwhile to ensure turn of the front-wheel shaft 3 when bearing axial force
It is dynamic flexible, miniature planar thrust ball bearing 24 is used at carrying, sliding friction is made to become rolling friction, and friction resistance is greatly reduced
Power.
To keep damping effect more preferably more reliable, shock mitigation system has used as shown in figure 4, being to use eight 26 Hes of butterfly spring
The composite structure of four elastic polyurethane pads 25, disk spring 26 are eight, and elastic polyurethane pad 25 is four, and arrangement mode is
It is three 25, two, elastic polyurethane pad, 26, two elastic polyurethane pads of disk spring of disk spring 26, two from the bottom up
25, three disk springs 26 can very well absorb impact energy when wheelchair jolts, and lower low-frequency vibration.
Two pairs of four folding struts 6 are rotatably connected between left vehicle frame 12 and right vehicle frame 11, every folds strut 6 in half
Arc-shaped, the semicircular arc open end of the folding strut 6 is connect with the upper and lower side of left vehicle frame 12 or right vehicle frame 11 respectively, two folding
The semicircular arc inner end of folded strut 6 is rotatablely connected by rotating pin 7 with link 8 is folded, and two are equipped on folding link 8
A linkage gear 9 being mutually twisted is set on each linkage gear 9 there are one dowel hole 15, the folding under each linkage gear 9
It is correspondingly provided with two location holes 16 on link 8, pull rod is connected between 8 inner end of folding link of folding strut 6 at two pairs
13, it is connected with draw ring 14 in the side outer end for folding link 8.
Workflow is as follows：A, fully collapsible invalid's chair process：Positioning pin 15 is extracted, draw ring 14 is pulled, in the control of linkage gear 9
Under, two edge contraction struts 6 will angularly turn to position shown in Fig. 7, and positioning pin 15 is fallen into location hole 16, and wheel-chair folds
Come.B, wheel-chair opening procedure：Positioning pin is extracted, pushes draw ring, until two edge contraction struts and pull rod 13 are in 90 °, positioning pin is fallen
Enter to open in location hole 16, wheel-chair is opened.
The fold mechanism of wheel-chair is generally campstool type structure, and wheel-chair height will increase about 30% when folding.The application
Design is slide folding mechanism, ensures that vehicle frame is reduced by about the ruler of two folding struts in a coordinate direction when folding
It is very little, other two coordinate direction size constancies.
The above is presently preferred embodiments of the present invention and its technical principle used, for those skilled in the art
For, without departing from the spirit and scope of the present invention, any equivalent change based on the basis of technical solution of the present invention
Change, simple replacement etc. is obvious changes, all fall within the protection scope of the present invention.
