The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are described.
In the present embodiment, the annexation between the main rod member of vehicle frame comprises shown in accompanying drawing 2,4,6:
The handspike 1 of pair of right and left;
The side stand 2 of the pair of right and left that the bottom of upper end and homonymy handspike 1 is rotationally connected around the 5th turning cylinder e, this bottom to side stand 2 is fixedly connected by foot-operated 13 of horizontally set;
The pair of right and left side connecting rod 3 that upper end and the bottom of homonymy handspike 1 are rotationally connected around the 7th turning cylinder g, and when vehicle frame was in deployed condition, the point of connection position between this side connecting rod 3 and the handspike 1 was lower than the point of connection position between side stand 2 and the handspike 1;
The bottom bracing frame 4 that constitutes by one group of four-bar linkage, bottom bar 20, preceding foot lever 11, back foot lever 12.
Above-mentioned four-bar linkage is by first connecting rod 7, second connecting rod 8, third connecting rod 9; Spring 10 constitutes.First connecting rod 7 rotates around the first turning cylinder a with second connecting rod 8 and is connected, and point of connection is first point of connection 16; Second connecting rod 8 rotates around the second turning cylinder b with third connecting rod 9 and is connected, and point of connection is second point of connection 17; Third connecting rod 9 rotates around the 3rd turning cylinder c with spring 10 and is connected, and point of connection is the 3rd point of connection 18; Spring 10 rotates around the 4th turning cylinder d with first connecting rod 7 and is connected, and point of connection is the 4th point of connection 19.
The structure that describes bottom bracing frame 4 by accompanying drawing 1,3,5 in detail is as follows.
The bottom of pair of right and left side connecting rod 3 all is connected on second point of connection 17, and all rotates with four-bar linkage around the second turning cylinder b and be connected.From in appearance, this offside connecting rod 3 has surrounded the U font.The leading section of bottom bar 20 rotates around the 6th turning cylinder with the bottom of side stand 2 and is connected, and the leading section of rearward end and first connecting rod 7 is fixedly connected.Second connecting rod 8 is the double-type setting in the left and right sides, and its upper end is clipped in the middle bottom bar 20 and rotates with first connecting rod 7 with bottom bar 20 and is connected, and the bottom of bottom and side connecting rod 3 and third connecting rod 9 rotate on second point of connection 17 and be connected.Be connected spring 10 between the 3rd point of connection 18 and the 4th point of connection 19 as the rod member of longitudinal extension, can play the effect of load-bearing, damping.From the middle part of third connecting rod 9, extend a pair of back foot lever 12 respectively towards the rear of both sides, trailing wheel 6 is installed in the rearward end of back foot lever 12.On foot-operated 13, extend a pair of preceding foot lever 11 respectively towards both sides, the outer end of foot lever 11 before front-wheel 5 is installed in.
On vehicle frame, also be provided with stretcher frame 14 and fence 15.Stretcher frame 14 is a reverse U shape, and its both ends rotate with the bottom of a pair of handspike 1 respectively and are connected.Fence 15 is similarly reverse U shape, and its both ends rotate with the upper end of pair of side brackets 2 respectively and are connected.
When folding, handspike 1 opposite side support 2 bends towards the place ahead around the 5th turning cylinder e, and the four-bar linkage that drives on the bottom bracing frame 4 by side connecting rod 3 is compressed into flats simultaneously, and whole vehicle frame is compressed into folded state as shown in Figure 5 on short transverse.Third connecting rod 9 in the four-bar linkage drives back foot lever 12 and is pulled to the place ahead, makes that the distance between front-wheel 5 and the trailing wheel 6 shortens, the volume after further having reduced to fold.After folding, it is parallel with handspike 1 that stretcher frame 14 and fence 15 all are bent into, and be sandwiched between handspike 1 and the side stand 2, can not influence the vehicle frame thickness after folding.
Folding, the expansion locking of whole vehicle frame are to realize by the lockout mechanism that is arranged between handspike 1 and the described side stand 2.In the present embodiment, be respectively arranged with the pair of locking face on handspike 1 and side stand 2, when vehicle frame was in deployed condition, lock face was conflicted mutually and is played position-limiting action.
As mentioned above, we are illustrated according to aim of the present invention fully, but the present invention is not limited to the foregoing description and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present invention.
