Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a frame structure of a reversing vehicle is shown in figures 1-5 and comprises an upper push rod 1, an upper periphery 3 of a lower push rod 2, a lower periphery rod 4, a side periphery 5, a front support 6, a rear support 7, a seat rod 8 and a basket rod 9.

Wherein, lower push rod 2 encloses the pole reciprocal anchorage down, goes up to enclose pole 3, encloses pole 4, side wall 5 and rear bracket 7 and articulates to be first four-bar linkage, and fore-stock 6, rear bracket 7, seat pole 8 and basket pole 9 articulate to be second four-bar linkage, and pendulum rod 10 articulates down and encloses pole 4 and basket pole 9 simultaneously, specifically, pendulum rod 10 and encloses pole and basket pole 9 under and articulate respectively in axle E and axle G down.

The arrangement of the swing rod realizes linkage of the first four-bar linkage structure and the second four-bar linkage structure.

Continuing to refer to attached figures 1 and 2, push down rod 2, enclose pole 4 and after-poppet 7 and articulate in axle D jointly, and this department is equipped with the torsional spring, and the effect of torsional spring lies in producing the pretightning force to when the frame expandes, the pretightning force of torsional spring can make and enclose pole anticlockwise rotation around axle D down, reaches automatic folding purpose.

The upper surrounding rod 3 and the lower surrounding rod 4 are arranged in a sliding mode, a lock 100 is arranged for unlocking the sliding mode, specifically, referring to fig. 1 and 2 and fig. 4 and 5, the upper push rod 1 and the lower push rod 2 are hinged to a shaft A, a lower push rod rotating block 21 of the lower push rod 2 at the shaft A is linked with a lower push rod sliding block 23 through a lower push rod steel wire rope 22, and the lower push rod sliding block 23 is linked with a lower surrounding rod sliding block 41 in the lower surrounding rod 4.

The lower enclosing rod sliding block 41 is connected with an unlocking block 1001 through a lower enclosing rod steel wire rope 42, the unlocking block 1001 acts on a lock tongue 1002 of the locking 100, and therefore unlocking can be achieved by rotating the upper push rod 1.

Continuing to refer to the attached figure 2, the upper enclosing rod 3 and the side enclosure 5 are hinged on a shaft B, and the side enclosure 5, the front bracket 6 and the rear bracket 7 are hinged on a shaft C together.

Furthermore, the seat rod 8 and the front bracket 6 are hinged to the shaft H, and the shaft H slides on the front bracket 6 to be adjustable.

All be equipped with wheel 200 on fore-stock 6 and the after-poppet 7, wheel 200 is detachable construction, and convenient transportation forms littleer volume with folding back.

Similarly, the tent pole arranged on the upper surrounding pole 3 is also designed to be detachable.

Further explaining by combining the folding mechanism, the frame in the unfolded state pushes the upper push rod upwards, the shaft A rotates and is linked to unlock and lock 100, and specifically, the shaft A rotates to drive the lower push rod rotating block to rotate and drive the lower push rod sliding block to slide under the action of the lower push rod steel wire rope.

And the lower push rod slider is linked with the lower surrounding rod slider to slide, and the locking unlocking block is pushed to unlock the locking tongue 1002 of the lock 100 under the action of the lower surrounding rod steel wire rope.

Meanwhile, referring specifically to fig. 3, the push down lever automatically rotates counterclockwise, i.e., downward, about the axis D under the influence of the torsion spring and the gravity of the frame.

Because lower push rod and enclosing pole down are fixed relation, enclose pole down and also rotate downwards along axle D in step, drive the side simultaneously and enclose along axle C and rotate downwards to go up enclosing pole and slide along enclosing pole down.

And then, the lower enclosing rod rotates and simultaneously drives the swing rod fixed at the lower end to move upwards at the position of the shaft E, the basket rod fixed at the other end of the swing rod is driven to rotate upwards at the shaft G, and the second four-bar linkage structure is driven to rotate and furl, so that the whole frame is automatically furled.

It is noted that with continued reference to fig. 6, in normal use of the frame, i.e., in the deployed condition, the front carrier assembly and seat bar assembly are hinged at the high point of axis H, i.e., H1 in the drawing.

When the frame is folded, the wheels and the awning rod set are detached, and the hinged shaft H of the front support and the seat rod is converted to a low point, namely the position H2 in the figure, so that the included angle between the front support and the rear support can be reduced, the folding volume is further reduced, and the packaging size of the frame is reduced.

To sum up, this scheme is rational in infrastructure, can complementary automatic folding after the unblock to, folding the secondary that can carry out the pivot point after accomplishing is folding, whole folding is small, and is folding convenient, and the practicality is strong, and user experience degree is high.
