Background technology
Perambulator butt is most important ground supports structure on the component and perambulator for installed on perambulator trailing wheel, common
Perambulator butt is not generally foldable, can not reduce perambulator whole height, and occupied space is larger, such as takes perambulator and drives to travel outdoors
When, such perambulator is difficult to pack into normal domestic use vehicle, even if being packed into the loading that may interfere with other articles, storage.For this purpose, perambulator is given birth to
Production producer develops vehicle frame foldable baby carriage, for example, Publication No. CN204895718U invention in public affairs on December 23rd, 2015
A kind of foldable chassis of perambulator has been opened, including headstock component, vehicle seat, Rear frame component, bicycle beam and frame state locking mechanism,
The headstock component rear end is hinged with bicycle beam front end, and the Rear frame component front end is hinged with bicycle beam rear lower, the vehicle seat peace
Mounted in top in the middle part of bicycle beam, the frame state locking mechanism includes locking level, spring, unfolded state locking piece, folded state
Locking piece, the unfolded state locking piece and folded state locking piece are separately mounted at the top of Rear frame component, the locking level
Top is hinged vehicle seat lateral surface, and spring is mounted on vehicle seat lateral surface and spring draws locking level toward lower left, the locking level
The expansion lock slots that can block unfolded state locking piece are provided in the middle part of left side, locking rod rear end, which is equipped with, can block folded state lock
Determine the foldable locking hook of part.Due to being improved frame state locking mechanism, structure is more reasonable for the invention, and
Easily fabricated and installation, easy to use, operation is more rapidly convenient.But the foldable chassis is by exposed frame state locking machine
Structure realizes that the state after frame state change is kept, and component is more, this base part is less coordinated with perambulator self structure, influences child
The appearance of vehicle.
The content of the invention
And, the present invention provides a kind of Pram folding vehicle frame knots in view of the above-mentioned defects in the prior art
