Problems solved by technology
At the beginning of the design of the foldable stroller, more attention was paid to the folding experience of the stroller. The current foldable stroller can usually be folded with one hand and one step. It is usually more complicated, and the foldable stroller cannot be unfolded with one hand, and the unfolding process is cumbersome, which is not friendly to parents holding infants and young children

The invention discloses an armrest frame linkage deployment mechanism, which is arranged at the pivot connection between the lower bracket of the foldable baby carriage and the backrest frame. The armrest frame linkage deployment mechanism comprises a fixing member fixedly arranged at the end of the backrest frame and the armrest link seat fixedly arranged at the end of the armrest frame, the end of the lower bracket, the fixing piece, and the armrest link seat are coaxially pivoted, and a push-up deployment structure is arranged between the armrest link seat and the fixing piece; The armrest linkage base can be pivoted relative to the fixing member to pivot the armrest frame to the deployed position, and the armrest linkage base can be pushed up and pivoted relative to the end of the lower bracket through the push-up deployment structure to expand the backrest frame; The armrest frame linkage deployment mechanism also includes a positioning member that can move relative to the fixed member and the armrest linkage base. When the armrest linkage base is pivoted relative to the fixed member to the deployment position, the positioning member can extend into the fixed member and the armrest linkage base. to limit the relative pivoting between the fixing piece and the armrest link seat.
Description
technical field [0001] The present invention relates to a foldable baby carriage, in particular to an armrest frame linkage deployment mechanism suitable for the foldable baby carriage. Background technique [0002] There are more and more collapsible strollers on the market. At the beginning of the design of the foldable stroller, more attention was paid to the folding experience of the stroller. The current foldable stroller can usually be folded in one step with one hand. Usually, it is more complicated, and the folding stroller cannot be unfolded with one hand, and the unfolding process is cumbersome, which is not friendly to parents with infants and young children in their arms. [0003] In this regard, it is necessary to provide an armrest frame linkage deployment mechanism that can realize the unfolding of a foldable baby carriage with one hand. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an armrest frame linkage deployment...
