Abstract
The utility model provides a baby carriage. A carriage frame thereof includes a front wheel bracket, a push bar with the lower part in rotational connection with the upper end part of the front wheel bracket, and a rear wheel bracket with the upper end part in rotational connection with the upper part of the front wheel bracket. The carriage frame further includes a seat bar with the front part in rotational connection with the front wheel bracket, an upper connecting bar with the upper end part in rotational connection with the lower end part of the push bar, and a lower connecting bar with the upper end part in rotational connection with the seat bar. The lower end part of the upper connecting bar is in rotational connection with the rear part of the seat bar; the lower end part of the lower connecting bar is in rotational connection with the rear wheel bracket; the push bar, the front wheel bracket, the seat bar and the upper connecting bar form a four-bar linkage; and the front wheel bracket, the seat bar, the lower connecting bar and the rear wheel bracket form a four-bar linkage.

Description
Technical field
The utility model relates to a kind of doll carriage.
Background technology
A kind of children trolley of the prior art is accepted by increasing family, can be with children trolley usually when travelling outdoors, can be for infant sitting, to alleviate caregiver's burden when children trolley is opened.Children trolley can fold reducing volume, and some children trolley all is on all fours after folding in the prior art, and floor area is bigger.And in the industry, the folding back of children trolley floor area is less to be the target that the designer pursues always.
The utility model content
Technical problem to be solved in the utility model provides the less children trolley of a kind of folding back floor area.
For solving above technical matters, the utility model is taked following technical scheme: a kind of doll carriage, comprise go-cart vehicle frame, front component, wheel assembly, be arranged on the lockout mechanism that is used for described go-cart vehicle frame is locked in open position on the described go-cart vehicle frame with open position and folding position
Described go-cart vehicle frame comprises the upper end of front-wheel support, bottom and described front-wheel support rotate bonded assembly push rod, rear wheel support;
The upper end of described rear wheel support is connected rotatedly with the top of described front-wheel support, and described go-cart vehicle frame also comprises
The seat bar, the front portion of described seat bar is connected rotatedly with described front-wheel support;
Boxed rod, the upper end of described boxed rod is connected rotatedly with the bottom of described push rod, the bottom of described boxed rod is connected rotatedly with the rear portion of described seat bar, and described push rod, described front-wheel support, described seat bar and described boxed rod constitute four-bar linkage;
Rear linking rod, the leading section of described rear linking rod is connected rotatedly with described seat bar, described rear linking rod is connected rotatedly with described rear wheel support, and described front-wheel support, described seat bar, described rear linking rod and described rear wheel support constitute four-bar linkage.The go-cart vehicle frame comprises two four-bar linkages, and these two four-bar linkages are interrelated, thereby as long as one of them four-bar linkage locking just can be locked the go-cart vehicle frame.When folding, earlier with the lockout mechanism release, two push rods are pushed over to the front lower place, two boxed rods drive the rear portion of two bars respectively and upwards move, and the front portion that two bars drive two rear linking rods is more also upwards moved, thereby the distance between two front-wheel supports and two rear wheel supports is furthered.
The place of being rotationally connected of the leading section of described rear linking rod and described seat bar is positioned at the bottom of described boxed rod and the place ahead that is rotationally connected and locates at the rear portion of described bar.
The place of being rotationally connected of described rear wheel support and described front-wheel support is positioned at the front lower place at the place that is rotationally connected of described push rod and described front-wheel support.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: since car load folding after, front component and wheel assembly still land, promptly children trolley is able to support oneself, thereby floor area is less after folding.
