Description
Technical field
The present invention relates to articles for children fields, and in particular to a kind of foldable baby stroller vehicle frame.
Background technique
Stroller has many types according to the difference of function, but usually all includes vehicle frame and seat two parts.In order to
Easy to carry and storage, manufacturer devise a kind of folding stroller, and the vehicle frame of this stroller can fold,
Purpose is that the diminution of volume is realized by folding, and solves the problems, such as that storage occupied space is big.However, existing stroller makes
Used time discovery, although vehicle frame can fold, facilitates storage, due to the Structure Designing Problem of vehicle frame, folded vehicle frame
The distance of its width direction is constant, therefore can not effectively reduce folded volume, after folded vehicle frame is put into automobile
When the confined spaces such as standby case, the problem of can not being put into often occurs, therefore be not able to satisfy the requirement of user.
That is, existing stroller can only accomplish unidirectional-folding mostly, i.e., fold in the front-back direction, and cannot achieve right and left
To folding, therefore deposit the problem that space hold is still larger after folding, either storage or carry and cannot make us full
Meaning.
Therefore, above-mentioned the shortcomings of the prior art how is solved, is become as the project of the invention to be researched and solved.

The seat support link 23 of 22 front ends, composition seat support link 23, which has, to be opened up and two states of downward folding.It designs whereby,
Space after vehicle frame folding can be further reduced.
Wherein, by the X-shaped support frame 9, first lateral folding bar 13, second lateral folding bar 16 and
The setting of the third lateral folding bar 19 can be realized simultaneously the lateral folding of each main component of the vehicle frame, can be realized
Further left and right folding makes the volume after folding minimum as far as possible to the vehicle frame while meeting conventional folding up and down
Change, greatly facilitates the storage and carrying when user's routine use.
More by the setting of the first locking mechanism 15 and the second locking mechanism 18, may be implemented to make vehicle frame
The locking of open state ensure that reliability of structure when vehicle frame is opened, and then ensure that safety when user uses, while
Improve the experience sense that user uses.
When vehicle frame folding, firstly, unlocking the first locking mechanism 15 and the second locking mechanism 18, make described
First lateral folding bar 13 and second lateral folding bar 16 are in after unlocking and state are freely rotated；Then, it receives respectively
The first, second, and third lateral folding bar 13,16,19 is rolled over, keeps two after-poppets, the push-rod frame and the fore-stock equal
It can be realized lateral folding；Meanwhile relatively rotating the push rod 1 around first hinge joint 4 with the front support rod 2, make two
Person's folding relative to the front support rod 2 close to and rotating the back stay 5 around second hinge joint 7, and then realize in height
It spends on direction and folding is carried out to vehicle frame；Not only height is smaller for vehicle frame after folding, while width also substantially reduces, after being allowed to folding
Volume minimization, to meet the storage demand of user.
When opening, by inverse operation step when folding.Compared to existing technologies, the present invention has after not only folding
Smaller volume, opens simultaneously, the operation of folding singlehanded can all be completed, very convenient；When opening, by be located at lower part the
One locking mechanism plays the main locking effect of vehicle frame, and the auxiliary of vehicle frame can be played by superposed second locking mechanism
Locking effect improves safety when user uses so that the opening state of vehicle frame is very reliable.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
