Abstract
A buggy is composed of a cart carriage, a rear wheel bracket, a front connecting rod and a push rod, wherein the cart carriage includes a front wheel bracket, and front wheel components are arranged at the front end part of the front wheel bracket; the rear part of the rear wheel bracket is rotatablely connected with the rear part of the front wheel bracket, and rear wheel components are arranged at the rear end part of the rear wheel bracket; the lower part of the front connecting rod is rotatablely connected with the front part of the front wheel bracket; the front part of the push rod is rotatablely connected with the upper part of the front connecting rod, and the push rod is also rotatablely connected with the front end part of the rear wheel bracket; a seat is arranged on the push rod; and the push rod, the rear wheel bracket, the front wheel bracket and the front connecting rod form a four-link mechanism. The cart carriage is reasonable in framework, and the seat can only be arranged on the push rod and can not be folded along with the folding of the cart carriage, thereby avoiding potential safety hazard; and the use is safe.
Description
Technical field
The present invention relates to a kind of carriage for children.
Background technology
Carriage for children, shown in Chinese publication CN1277124, the seat of carriage for children is arranged between the many rod members, thereby the seat will be involved during the go-cart vehicle frame folding, and promptly when the go-cart vehicle frame folding, the seat also will fold gathering.If be sitting on the carriage for children as children, this moment, carriage for children was improper folding, the children that are sitting on the carriage for children are come to harm, thereby have potential safety hazard, and the seat of most of perambulator of the prior art such phenomenon of ubiquity all.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of behind the go-cart vehicle frame folding, the carriage for children that seat itself can not fold.
For achieving the above object, the technical solution used in the present invention is: a kind of carriage for children, comprise the go-cart vehicle frame with expanded position and folding position, the front component that is arranged on described go-cart bottom of frame and 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, described front-wheel support can be for single, and single front-wheel support is positioned at the middle part, the end of go-cart vehicle frame, and extends along fore-and-aft direction, also can be two, and two front-wheel supports then lay respectively at the both sides of go-cart vehicle frame;
Rear wheel support, the rear portion of described rear wheel support rotate with the rear portion of described front-wheel support and are connected;
Front rod, the bottom of described front rod rotate with the front portion of described front-wheel support and are connected;
Push rod, the front portion of described push rod is connected rotatedly with the top of described front rod, and described push rod also is connected rotatedly with the leading section of described rear wheel support, described seat is arranged on the described push rod, and described push rod, described rear wheel support, described front-wheel support and described front rod constitute four-bar linkage.Any one rotary joint just can lock the go-cart vehicle frame car load lockout mechanism in this four-bar linkage as long as pin.After the release of described car load lockout mechanism, the rearward end of described push rod is pressed to the back lower place, under the effect of four-bar linkage, the go-cart vehicle frame is just folding.
Described go-cart vehicle frame also comprises
By first rod member and the second rod member slide relative expansion link that is constituted is set, in the leading section of described first rod member and described front rod, two parts of described front-wheel support at least one can be rotationally connected mutually, and described second rod member is connected rotatedly with described rear wheel support.
Described car load lockout mechanism is locked at least two expanded positions with described go-cart vehicle frame, and correspondingly described expansion link is locked at least two positions, and described expansion link all has stroke between per two positions.This structure is preferred.Described length of telescopic bar has determined the angle position at seat, the angle position at seat make the running condition at seat can be for the seat pocketed attitude used for the children that can sit, can also be infancy seat state for the children's use that can not sit.
Described car load lockout mechanism comprise be arranged between described second rod member and described first rod member and be used for both locking first lockout mechanism.After the locking of described first rod member and described second rod member was the expansion link locking, described expansion link, described rear wheel support and described front-wheel support had just constituted triangle stably, and promptly rotation place between front-wheel support and the rear wheel support is locked.First lockout mechanism can be realized by multiple structure of the prior art.Can only get final product locking between first rod member of slide relative and second rod member.
Described first lockout mechanism comprises along the length direction of described first rod member and is opened at least two lockholes on described first rod member, is slidingly arranged in the bullet pin on described second rod member, and the incompatible realization that matches of described bullet pin and described lockhole is locked as preferably.Hooking the realization locking as latch hook also is fine.
Described expansion link is a cylinder.Also can be between described first rod member and described second rod member, spring to be set.Thereby make described go-cart vehicle frame in the folding position in the process of expanded position conversion, make the go-cart vehicle frame have the trend that trends towards expanded position.
Described car load lockout mechanism also comprises second lockout mechanism at the place that is rotationally connected that is arranged on described push rod and described front rod.Second lockout mechanism can lock the go-cart vehicle frame, and be in the lock state down at first lockout mechanism, second lockout mechanism is not essential, and described second lockout mechanism makes that the stability of go-cart vehicle frame under expanded position is stronger, same, described second lockout mechanism can be realized by multiple structure of the prior art.
Because technique scheme utilization, the present invention compared with prior art has following advantage: because go-cart vehicle frame framework is reasonable, the seat can only be arranged on the push rod, and promptly seat itself can not folding owing to the go-cart vehicle frame, thereby avoided potential safety hazard, use safer.
