Specifically, seeing shown in each accompanying drawing, front tension bar 4 the most gradually updip is extended, and this front tension bar 4 is positioned at Below the rear side of fore-stock 1, the front end of front tension bar 4 is pivotally connected on the bottom of fore-stock 1;Back stay 5 the most from back to front by Gradually updip is extended, and back stay 5 is positioned at below the front side of after-poppet 2, and the rear end of back stay 5 is pivotally connected in after-poppet 2 On bottom.In the present embodiment, wheel assembly includes front-wheel 20 and trailing wheel 30, and front-wheel 20 at least includes being fixed on fore-stock 1 lower end Front-wheel seat 20a, trailing wheel 30 at least includes the rear wheel seat 30a being fixed on after-poppet 2 lower end, and the front end of front tension bar 4 is pivotally connected On front-wheel seat 20a, the rear end of back stay 5 is pivotally connected on rear wheel seat 30a.
In the present embodiment, the first axle is passed through (in figure in the bottom of the top of fore-stock 1, the top of after-poppet 2 and push rod 3 Not shown) phase pivot links together, and the upper end of connecting rod 6 is pivotally connected in push rod 3 times by the second axle (not shown) End, the axial line of the first axle and the second axle is arranged in parallel, and both axial line non-colinears extend.
The rear end of front tension bar 4 can be respectively connecting on the lower end of connecting rod 6 with the front end of back stay 5, it is also possible to such as this enforcement Example uses the lower end of the rear end of front tension bar 4, the front end of back stay 5 and connecting rod 6 is linked together around same rotating shaft phase pivot. Specifically, in the present embodiment, shown in Figure 1, connecting rod 6 includes the cross bar portion 61 extended in left-right direction, from cross bar portion 61 Respective upwardly extending side lever portion, two ends 62, form opening up U-shaped between side lever portion 62 and the cross bar portion 61 of both sides, The front end of the rear end of front tension bar 4 and back stay 5 is rotatably connected in cross bar portion 61 rotating around the axial line in cross bar portion 61.
In the present embodiment, fore-stock 1 at least includes the front support rod being positioned at the left and right sides, and after-poppet 2 at least includes being positioned at The back stay of the left and right sides, front tension bar 4, back stay 5 have two respectively and lay respectively at the left and right sides, push rod 3 also have two and Lay respectively at the left and right sides.On the same side of vehicle frame, the lower end of the upper end of front support rod, the upper end of back stay and push rod 3 is around same Axial line is pivotally connected to together, and the upper end, side lever portion 62 of connecting rod 6 is pivotally connected to this side push rod 3 around another axial line On, the rear end of front tension bar 4, the front end of back stay 5 are pivotally connected to cross bar portion rotating around the axial line in connecting rod 6 cross tube portion 61 On 61.So, on the same side of vehicle frame, between front support rod, front tension bar 4, connecting rod 6 and push rod 3, constitute the first quadric chain, after The second quadric chain is constituted between pole, back stay 5, connecting rod 6 and push rod 3.
Locking mechanism includes the two groups of locking joint pieces 8 laying respectively at the left and right sides, and this locking joint piece 8 is located at front support rod Upper end, the upper end of back stay and push rod 3 lower end between for by three lock, this locking joint piece 8 can make when locking First quadric chain and the second quadric chain are locked simultaneously.
Seeing shown in each accompanying drawing, the upper end of push rod 3 is the most pivotally connected handle 6, this handle 6 in downward opening U-shaped, The lower end in its two side levers portion push rod 3 upper end phase pivot respectively at both sides connects, and the lower end of handle 6 is with end pivoting on push rod 3 even The place of connecing is additionally provided with the handle locking piece 9 for both being locked, to be locked under multiple use state by relative for handle 7 push rod 3. When arranging, handle locking piece 9 can be set to and locking joint piece 8 linkage of unlocking, such as, in certain embodiments, can arrange Just can be by the structure of handle locking piece 9 with locking joint piece 8 synchronizing unlocking when drawing close for relative for handle 7 push rod 3 is overturn forward.
Seeing shown in Fig. 1, Fig. 2, when vehicle frame is locked in deployed condition, fore-stock 1 and push rod 3 are approximately along same length direction The most gradually updip extends, and front tension bar 4, back stay 5 and connecting rod 6 are positioned at the space below fore-stock 1 and after-poppet 2, Constitute triangular structure between fore-stock 1, front tension bar 4 and connecting rod 6, also constitute between after-poppet 2, back stay 5 and connecting rod 6 Triangular structure;Handle 7 upwardly extends from the top of push rod 3 and passes through handle locking piece 9 and locks, and can carry out needs according to reality Operate handle locking piece 9 and adjust the relative position of the relative push rod 3 of handle 7.The letter very of vehicle frame structure in the folded-out situation Clean.
When vehicle frame folding is got up by needs, see shown in Fig. 3, Fig. 4, first handle 7 is overturn forward and relatively push rod 3 leans on Holding together, be then pressed downward against push rod 3 and make its relative after-poppet 2 turn over, the upper end of the lower end drivening rod 6 of push rod 3 is up so that Connecting rod 6 drives front tension bar 4 and back stay 5 to overturn relative to fore-stock 1, after-poppet 2 respectively, and drives fore-stock 1 and after-poppet 2 edge Fore-and-aft direction is gradually drawn close.Finally, as shown in Figure 5, Figure 6, together with fore-stock 1 draws in along the longitudinal direction with after-poppet 2, front draw Bar 4, back stay 5 and connecting rod 6 draw between fore-stock 1 and after-poppet 2, and push rod 3 draws close the rear side at after-poppet 2.After folding Body frame structure for automotive very compact, take up room the least.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this. All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it In.
