Abstract
The utility model provides a foldable baby carriage. A carriage frame thereof includes a front wheel bracket, a rear wheel bracket with a front end part rotationally connected with the lower part of the front wheel bracket, a pushing bar with a lower part rotationally connected with the upper end part of the front wheel bracket, an upper connecting bar with an upper end part rotationally connected with the lower end part of the pushing bar, a seat bar with a front part rotationally connected with the front wheel bracket, and a lower connecting bar with a lower part rotationally connected with the rear wheel bracket. The lower part of the upper connecting bar is rotationally connected with the seat bar; the upper end part of the lower connecting bar is rotationally connected with the seat bar; the front wheel bracket, the pushing bar, the upper connecting bar and the seat bar form a four-bar linkage; and the front wheel bracket, the seat bar, the lower connecting bar and the rear wheel bracket also form a four-bar linkage. The utility model provides an unique design scheme with the technical effect achieving the level of the prior art, the included angle between a bottom support leg and a horizontal plane is small, four wheels of the baby carriage can land even after being folded, the seat can not be in contact with the ground, and the structure is simple.
Description
Technical field
The utility model relates to a kind of folding children's barrow.
Background technology
Shown in China's bulletin patent 03122053.3, before the go-cart vehicle frame of this Folding trolley comprises support leg, bottom with described before support leg the upper end bottom of bonded assembly push rod, upper end and the described push rod bottom of bonded assembly strut bar, leading section and the preceding support leg bonded assembly bottom bracing leg that rotates that rotates that rotates, the bottom of described supporting leg is connected rotatedly with described bottom bracing leg, and described preceding support leg, described push rod, described supporting leg and described bottom bracing leg constitute four-bar linkage.Angle between this bottom bracing leg and the horizontal surface is less, and this folded bicycle still lands at folding back four-wheel, and the seat can not contact with ground, this also when the design children trolley designer pursue always.
The utility model content
The angle that technical problem to be solved in the utility model provides between a kind of bottom bracing leg and the horizontal surface is less, and this folded bicycle folding back four-wheel still land and the seat not can with the contacted folding children's barrow in ground.
For solving above technical matters, the utility model is taked following technical scheme: a kind of folding children's barrow, comprise go-cart vehicle frame with expanded position and folding position, be arranged on the front component of front portion at the bottom of the described go-cart vehicle frame and rear portion, the end wheel assembly, seat, be used for described go-cart vehicle frame is locked in the car load lockout mechanism of expanded position, described go-cart vehicle frame comprises
Front-wheel support;
Rear wheel support, the leading section of described rear wheel support is connected rotatedly with the bottom of described front-wheel support;
Push rod, the bottom of described push rod is connected rotatedly with the upper end of described front-wheel support, and described go-cart vehicle frame also comprises
Boxed rod, the upper end of described boxed rod is connected rotatedly with the bottom of described push rod;
Seat post, the front portion of described seat post is connected rotatedly with described front-wheel support, and the bottom of described boxed rod is connected rotatedly with described seat post;
Lower link, the bottom of described lower link is connected rotatedly with described rear wheel support, and the upper end of described lower link is connected rotatedly with described seat post,
Described front-wheel support, described push rod, described boxed rod and described seat post constitute four-bar linkage,
Described front-wheel support, described seat post, described lower link and described rear wheel support also constitute four-bar linkage, and the car load lockout mechanism only need just can lock any run-on point locking in two four-bar linkages with the go-cart vehicle frame.After with the release of car load lockout mechanism, push rod is pushed over downwards forward, under the interlock effect under two four-bar linkages, the go-cart vehicle frame just has been folded, and after folding, front-wheel support is folded with rear wheel support mutually.
The top same axis of the bottom of described boxed rod, described seat post and described lower link is rotationally connected to preferably, also can be two turning cylinders.
Described car load lockout mechanism is arranged between the top of the bottom of described push rod and described front-wheel support to preferred.
Described front component is arranged at the bottom of described front-wheel support.
Described wheel assembly is arranged at the rear portion of described rear wheel support.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: the utility model provides a kind of technical conceive different technical schemes, but its technique effect can reach the level of prior art, angle between bottom bracing leg and the horizontal surface is less, this children trolley still lands at folding back four-wheel, the seat can not contact with ground, and structure is also simpler.
