Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
below about in the definition in direction, be all according to this children trolley be in launch using state time, the direction that the outlook on children of sitting on children trolley observes defines, the left and right directions in fore-and-aft direction that is each accompanying drawing, and wherein, left is front, after right is; Above-below direction that is the above-below direction shown in Fig. 1.
see the children trolley shown in Fig. 1 to Fig. 3, comprise there is deployed condition and folded state stroller frame, be located at wheel assembly bottom stroller frame, for by stroller frame locking lockout mechanism in the deployed state.
this stroller frame comprises front frame 1, after poppet 2, push rod 3, upper connecting rod 4 and lower link 5, and wheel assembly comprises the front component 10 be located at respectively bottom front frame 1 and the wheel assembly 20 be located at bottom after poppet 2.Front frame 1 is mutually arranged in a crossed manner with after poppet 2, and after poppet 2 head lamp brush guard pivot is connected with a sliding part 6, this sliding part 6 can be located on front frame 1 along the length bearing of trend of front frame 1 slidably, and like this, after poppet 2 is not only rotatable but also can relatively slide by after poppet 2 relatively just can to make front frame 1.Herein, what sliding part 6 adopted is sliding sleeve, and this sliding sleeve is pivotally connected on after poppet 2 by the second axle 8.
the top of after poppet 2 is connected with the bottom phase pivot of push rod 3, and the upper pivot of upper connecting rod 4 is connected on push rod 3, and the bottom of lower link 5 is pivotally connected on after poppet 2 by the first axle 7, and this first axle 7 is positioned at the below of the second axle 8 on after poppet 2.In these three parts of top of the top of front frame 1, the bottom of upper connecting rod 4 and lower link 5, wherein two parts phase pivots connect, and the 3rd parts are connected with a parts phase pivot in above-mentioned two parts.When vehicle frame launches, between the extended line at upper connecting rod 4 place and the extended line at lower link 5 place, there is angle.In the present embodiment, the bottom of upper connecting rod 4 and the top of lower link 5 are pivotally connected in the top of front frame 1 respectively.The upper pivot of the top of the bottom of upper connecting rod 4, lower link 5 and front frame 1 can certainly be connected to same place.Here, for making upper connecting rod 4 can all draw close mutually with front frame 1 with lower link 5 and making stroller frame compacter after folding, the top of front frame 1 is fixedly provided with connection end 9, the length bearing of trend of this connection end 9 and the length bearing of trend of front frame 1 tilt or arrange mutual vertically, and the bottom of upper connecting rod 4 and the top of lower link 5 are pivotally connected on two axial end portions of connection end 9 respectively.
lockout mechanism is be located at the locking piece for both being locked between sliding part 6 and front frame 1, unlock piece (not shown) for unlocking locking piece can be located at the top of front frame 1, and lockout mechanism can unlock at the rear portion of go-cart and fold stroller frame by such operator.
when this stroller frame is launched, shown in Figure 1, the locking piece of lockout mechanism is in the lock state, and sliding part 6 relatively front frame 1 is fixed, lower link 5 is supported between front frame 1 and after poppet 2, forms triangular structure between lower link 5 and front frame 1, after poppet 2; Upper connecting rod 4 is supported between push rod 3 and front frame 1, and form four-bar linkage between push rod 3, front frame 1, after poppet 2 and upper connecting rod 4, stroller frame is in stable deployed condition.When stroller frame folds by needs, unlocked by locking piece from the rear of stroller frame by unlock piece, sliding part 6 and front frame 1 can relative slidings.
now under the effect of each rod member self gravitation of stroller frame, front frame 1 and after poppet 2 relatively rotate and reduce height, glide along the length direction of front frame 1 at the effect lower slider 6 of lower link 5, after poppet 2 drives push rod 3 and upper connecting rod 4 all to relatively rotate and draws in front frame 1 and after poppet 2 gradually, finally, front frame 1, after poppet 2, push rod 3, upper connecting rod 4 and push rod 5 are drawn close together mutually, form state as shown in Figure 3.Compact conformation after folding, takes up room little.
when this stroller frame opened by needs, then only need to carry push rod 3, under the drive of push rod 3, after poppet 2 to rotate and sliding part 6 is upper sliding gradually along front frame 1 relative to front frame 1, upper connecting rod 4 and lower link 5 launch gradually thereupon rotating, until locking piece locking when each rod member launches completely, under stroller frame just can be in stable deployed condition.
to sum up, this children trolley, its rod member quantity is few, and structure is simple, and launch with folding operation all very convenient, after folding, each rod member can closely draw in together, and take up room little, user can be deposited and carry easily.
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.
