The utility model embodiment accompanying drawings is as follows:
Fig. 1 folds the anti-vibration bicycle structural representation;
Fig. 2 folded state bicycle scheme drawing;
Anti-vibration structure cutaway view behind Fig. 3;
Fig. 4 front shock-proof device structure cutaway view;
Fig. 5 folds the position locking structural scheme of mechanism.
As shown in Figure 1, this car comprises front vehicle wheel 1, front vehicle frame 2, a handle of handlebar upright 3 and a horizontal stroke 5, this car forebody is installed with common car identical, vehicle seat 7 is installed on the vehicle seat pipe support 6, vehicle seat pipe support below is hinged with radius stay 41 1 ends, the central sill of the radius stay other end and front vehicle frame 2 is hinged and vehicle seat pipe support lower surface is contacted and triangular in shape with central sill with hinge 26, at vehicle seat pipe support lower end a shock-proof block 15 is installed, with hinged and it is contacted with central axis seat below the front end of the fixing folded frame 13 of the back vent that trailing wheel 12 is housed of central axis seat 42 and the front vehicle frame central sill with hinge 25, also can between front vehicle frame central sill lower end and central axis seat, install the back shock absorbing apparatus additional and see Fig. 3, folded frame front end of back vent and vehicle seat pipe support lower end are hinged with return bar 14 two ends respectively, between folded frame of back vent and front vehicle frame central sill lower end, folding catch gear is installed, wherein folded frame of back vent and front vehicle frame central sill adopt shape tube, between axis and the trailing wheel chain drive is installed, the front end of clothes hanger 9 is hinged by hinge 40 and vehicle seat pipe support, the two ends of clothes hanger pole 8 are hinged by hinge 24 with clothes hanger and front vehicle frame central sill lower end respectively, supporting seat 29 is housed below clothes hanger sees Fig. 5, the folded position latch hook 11 that has cage knob and cooperate with the central sill lower end wherein is installed, locking spring 27 is installed between locating dowel pin 28 under clothes hanger and the latch hook is constituted folded position locking mechanism, comprise that at the folding catch gear between the folded frame of back vent being fixed on back vent folds the limiting stopper 16 on the frame and be installed in the operating crank 10 that cooperates with the central sill lower end between the folded frame of back vent, and the locking spring of installing between crank and folded frame 17 constitutes, see Fig. 3 in central sill lower end and crank 10 contact positions guar plate 18 of installation, wherein the back shock absorbing apparatus comprises that the shock-absorbing seat 22 that is fixed on the central axis seat and suit use the spacing shock resistance block 19 of pin 21 thereon, shock-proof spring 20 is installed between central axis seat and the shock resistance block, the spacing rubber cradle 23 of while suit on the shock-absorbing seat, the shock resistance block upper surface contacts and is designed to circular arc camber with the central sill lower surface.See Fig. 4 at a horizontal stroke of handlebar and the front shock-proof device device is installed between upright, front shock-proof device shell 4 is by being fixed on horizontal clips 37 and bolt 38 horizontal middle part of fixing with it on one side, shell 4 upper ends are hinged with a upright upper end by bearing pin 39, shock-absorbing pin 35 is from packing ring 36 front shock-proof device shells and passing the hole on the upright shock-absorbing box of fixing 32, vibration damping spring 34 in the shock-absorbing box is enclosed within on the shock-absorbing pin and uses packing ring 33, and locknut 30, locking plate 31 are fixed on the shock-absorbing pin.
This car is at running condition such as Fig. 1, shown in Figure 3, and the operating crank 10 in the folding latching device is close to its lower end with limiting stopper 16 and passes through guar plate 18 with front vehicle frame central sill lower end fixing and locking under spring 17 effects.When folding 10 inverse times of crank are rotated, when treating that it screws out the central sill lower end, with the folded frame up time backspin of back vent, the folded frame front end promotion of back vent this moment return bar 14 drive vehicle seat pipe supports and central sill are close, then up time and vehicle seat pipe support are close to the utmost point spacing downwards for clothes hanger, folded position latch hook 11 in the folded position locking mechanism is hung over central sill 2 lower end cambered surface intersections finish folded position locking and see Fig. 2, during use latch hook 11 outward turning reverse operatings are got final product.
