Description
[ field of technology ]
The invention relates to a baby carriage frame.
[ background Art ]
Currently, many commercial child vehicles include a collapsible child vehicle frame and a collapsible child seat attached to the child vehicle frame.
The perambulator has a structural scheme of one-key car collection and a structural scheme of step car collection; for the structural scheme of a one-key folding vehicle, as disclosed in China CN107428355B, when the folding vehicle is folded, the backrest unlocking mechanism is manually operated to release the locking state of the backrest relative to the seat part, then the backrest is operated to rotate towards one side of the seat part to close the seat part, so that the folding of the child seat is realized, when the backrest rotates to a preset angle relative to the seat part, the linkage seat part is unlocked relative to the vehicle frame, the seat part is turned over under the action of gravity after being unlocked relative to the vehicle frame, and then the joint of the linkage vehicle frame is unlocked, so that the one-key folding of the whole vehicle is finally realized. However, the frame of the baby carrier designed by adopting the scheme has high linkage matching requirement and high requirements on the manufacturing precision, the service life and the assembly of related parts, and therefore, the frame of the baby carrier adopting the structural design has high manufacturing cost and is not beneficial to improving the market competitiveness of products; in addition, the phenomenon of folding and clamping stagnation is easy to occur due to fatigue abrasion and assembly gaps of parts in the using process.
For the structural scheme of the step-by-step folding vehicle, the backrest unlocking mechanism is manually operated to release the locking state of the backrest relative to the seat part, then the backrest is operated to rotate towards one side of the seat part to fold the child seat, after the backrest is folded on the seat part, the locking relation between the seat part and the vehicle frame is unlocked, the seat part is turned over under the action of gravity after being unlocked relative to the vehicle frame, and the vehicle frame is further linked to be articulated for unlocking, so that the folding of the whole vehicle is finally realized. The scheme has the advantages of step operation, higher reliability and stability and lower manufacturing cost, so that the product has good market competitiveness. The structure also has problems at that time: after the seat part is unlocked relative to the frame, the seat part is overturned under the action of gravity, and if the gravity of the seat part is insufficient, the frame can not be driven to unlock, so that the folding clamping stagnation phenomenon exists. If the seat part is designed to have larger gravity, the weight of the whole vehicle is correspondingly increased, so that the carrying out is inconvenient.
The present invention has been made in view of the above problems.
