Baby carriage and backrest angle adjusting mechanism thereof

Abstract

The invention discloses a backrest angle adjusting mechanism which comprises a first fixing seat, a second fixing seat, a locking piece and a driving piece. The first fixing seat and the second fixing seat are pivoted and are respectively connected to the backrest pipe and the frame, and a plurality of clamping sections are formed between the first fixing seat and the second fixing seat; the locking piece is arranged between the first fixing seat and the second fixing seat in a sliding mode and is provided with a locking position and an unlocking position, when the locking piece is located at the locking position, the locking piece is clamped to any clamping section position, when the driving piece moves, the locking piece can be driven to be separated from the clamping section positions in a sliding mode to be located at the unlocking position, and therefore angle adjustment of the backrest pipe can be achieved. In the folding process of the frame, the backrest tube can be pulled to move along with the frame through folding of the frame or the seat cloth, automatic folding of the backrest tube is achieved, and therefore angle adjustment of the backrest tube and folding operation of the baby carriage are simpler and more convenient. The invention further discloses a baby carriage with the backrest angle adjusting mechanism.

Description

technical field [0001] The invention relates to the technical field of infant vehicles, in particular to a backrest angle adjustment mechanism which can adjust the angle and can be automatically folded along with the vehicle frame, and a baby carriage with the mechanism.

AI Technical Summary

Problems solved by technology

[0003] In order to realize the adjustment of the backrest, locking mechanisms are usually provided at the pivotal positions at both ends of the backrest, and the backrest can be adjusted by releasing the locking mechanism through operation, but usually both hands need to be operated at the same time to make both sides This will cause very inconvenient operation, especially if it can only be operated with one hand; moreover, when the stroller is folded, the seat and backrest on it generally cannot be automatically retracted with the frame. close, resulting in cumbersome closing operation
