Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
see the children trolley shown in Fig. 1 to Fig. 5, comprise the stroller frame with deployed condition and folded state, the front component 20 being located at front portion at the bottom of stroller frame, the wheel assembly 30 of being located at rear portion at the bottom of stroller frame, and for this stroller frame being locked in the lockout mechanism of deployed condition.
stroller frame comprises the push rod 3 that the underframe 1, the lower pivot that extend along the longitudinal direction are connected to the connecting rod 2 of underframe 1 front portion, bottom is connected with the top phase pivot of connecting rod 2, and lower pivot is connected to the support 4 at underframe 1 rear portion, the upper pivot of support 4 is connected on push rod 3, just constitutes four-bar linkage between underframe 1, connecting rod 2, push rod 3 and support 4.This stroller frame also comprises rear wheel frame 6, and the upper pivot of this rear wheel frame 6 is connected to the rear portion of underframe 1, and wheel assembly 30 is arranged on the bottom of rear wheel frame 6.When stroller frame is in deployed condition, push rod 3 and connecting rod 2 extend along same length direction, make to form triangular structure between underframe 1, connecting rod 2, push rod 3 and support 4, structure when stroller frame can be made like this to launch is more stable, meanwhile, rear wheel frame 6 and wheel assembly 30 are stably supported on the rear portion, the end of underframe 1; When stroller frame is in folded state, connecting rod 2, push rod 3 and support 4 all draw in underframe 1 and are positioned at the top of underframe 1, and rear wheel frame 6 drives wheel assembly 30 to bend and draws in the bottom of underframe 1.
lockout mechanism comprises frame locking mechanism 5 and rear wheel frame lockout mechanism 7.Frame locking mechanism 5 can be located at for the locking between these two rod members between rod member that any two phase pivots in above-mentioned four-bar linkage connect, under this four-bar linkage so just can be made to be in stable expanded position.Frame locking mechanism 5 can adopt the rotary joint parts of locking locking member, i.e. electric bell structure.In the present embodiment, frame locking mechanism 5 is located at connecting rod 2 and the pivotal joint place of push rod 3, and stroller frame can be made like this to have good rigidity.Push rod 3 is provided with the unblock handle 10 for unlocking this frame locking mechanism 5.Rear wheel frame lockout mechanism 7 is located at the pivotal joint place of rear wheel frame 6 and underframe 1, and it also can adopt electric bell structure.
this rear wheel frame lockout mechanism 7 can be made when arranging to arrange with frame locking mechanism 5 linkage of unlocking.Arrange in the following manner in the present embodiment: after frame locking mechanism 5 unlocks, the four-bar linkage formed between connecting rod 2, push rod 3, support 4 and underframe 1 is in active state, when underframe 1 overturns forward support 4 relatively, rear wheel frame lockout mechanism 7 just can be driven to unlock.
in the present embodiment, support 4 adopts with vibration damping spring 41 and along the shock-absorbing support of its length direction elastic telescopic, can play good cushioning effect like this to stroller frame, reduces the human discomfort because road bump causes the children of sitting in go-cart.
shown in each accompanying drawing, this stroller frame also comprises the handle 8 being located at push rod 3 top, the bottom of this handle 8 is connected with the top phase pivot of push rod 3, the handle lockout mechanism 9 for both being locked is provided with between handle 8 and push rod 3, this handle lockout mechanism 9 also can adopt electric bell structure, and is located at the pivotal joint place between handle 8 and push rod 3.Can make like this handle 8 relatively push rod 3 there is multiple use location, so that integrally-built gathering when the adjustment needs of handle 8 position and stroller frame fold when carrying out.
in the present embodiment, on the front portion, the end of underframe 1, front component 20 is set to one group, and on the rear portion, the end of underframe 1, wheel assembly 30 is provided with two groups, and these two groups of wheel assemblies 30 lay respectively at the left and right sides of underframe 1.In addition, the rear wheel rotation footpath of wheel assembly 30 is greater than the front-wheel wheel footpath of front component 20, and this children trolley can be made like this to be used as foldable carriage for child, lighter during implementation, laborsaving.
shown in Fig. 1, Fig. 2, when this children trolley is in deployed condition, connecting rod 2 and push rod 3 extend along same length direction, connecting rod 2, push rod 3 and form stable triangular structure between support 4 and underframe 1, and rear wheel frame 6 and wheel assembly 30 are stably supported on the rear portion of underframe 1.
when this stroller frame folds by needs, first by unlocking handle 10, frame locking mechanism 5 being unlocked, making the four-bar linkage of the activity formed between underframe 1, connecting rod 2, push rod 3 and support 4.Driven forward push rod 3, drivening rod 2 relatively underframe 1 overturns forward, drives the relative underframe 1 of support 4 to overturn forward simultaneously, connecting rod 2, push rod 3 and support 4 are drawn close to underframe 1 gradually; In the process of turning over before support 4 relatively underframe 1, rear wheel frame lockout mechanism 7 is unlocked, draw in completely behind the top of underframe 1 until connecting rod 2, push rod 3 and support 4, as shown in Figure 3, to rear wheel frame 6 one power forward, turn over before making the relative underframe 1 of rear wheel frame 6, making rear wheel frame 6 be communicated with wheel assembly 30 draws in the bottom of underframe 1, state as shown in Figure 4, finally again handle lockout mechanism 9 is unlocked and handle 8 is rotated relative to push rod 3, itself and vehicle frame are drawn in thus reduces the go-cart overall dimensions after folding, as shown in Figure 5.Compact conformation after this children trolley folds, small volume, can be easy to carry and deposit.
when this stroller frame is launched by needs, first turn on handle 8 relatively push rod 3, then the four-bar linkage pulling push rod 2 that underframe 1, connecting rod 2, push rod 3 and support 4 are formed is movable and relatively launch gradually, makes its relative underframe 1 turn over afterwards gradually thus make wheel assembly 30 be supported in ground together with front component 20 to rear wheel frame 6 one power backward simultaneously.After vehicle frame launches completely, frame locking mechanism 5 and rear wheel frame lockout mechanism 7 lock, under go-cart is just in stable deployed condition.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
