AI Technical Summary

Technical Problem

The limiting mechanisms of existing strollers are complex, affecting the ease of operation and safety. Furthermore, foldable strollers pose a risk of accidental operation by children during the folding process, leading to unsafe use.

Method used

Design a simple limiting mechanism that can be rotatably set on a fixed base by a locking component to limit and release the vehicle body, simplifying operation. The mechanism can also synchronously control the locking and unlocking of multiple frame components through an actuation mechanism, improving folding efficiency and safety.

Benefits of technology

The limiting mechanism allows for convenient operation without affecting the overall appearance of the stroller, improving the safety and folding efficiency of the stroller and reducing the risk of children misoperating it.

Abstract

This invention relates to a trolley. The trolley includes a frame, an armrest, and a stop mechanism. The frame includes a seat frame and is in an unfolded state. The armrest is pivotally connected to the frame. When the frame is in the unfolded state, the armrest has a first open position and a second open position, with the first open position being closer to the seat frame than the second open position. The stop mechanism is disposed between the frame and the armrest and is adapted to prevent the armrest from switching from the first open position to the second open position.
