The frame folding structure 10 of a child stroller according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 7 , the frame folding structure 10 of the child stroller according to the embodiment of the utility model includes a handlebar transfer rod 100 , a front wheel transfer rod 200 , a locking member 300 , a main frame 500 , a first connecting rod 600 and a second connecting rod 700 .

The end of the handlebar transfer rod 100 and the end of the front wheel transfer rod 200 are pivotally connected through the main shaft 400. The locking member 300 is movably arranged on the handlebar transfer rod 100 between a locked state and a released state. The main frame 500 is provided with a locking groove 520 and a secondary shaft 800. The locking member 300 is engaged in the locking groove 520 in the locked state and is suitable for being separated from the locking groove 520 in the released state. The first connecting rod 600 is pivotally connected to the middle part of the front wheel transfer rod 200 and the secondary shaft 800 respectively. The second connecting rod 700 is pivotally connected to the middle part of the handlebar transfer rod 100 and the secondary shaft 800 respectively.

It should be understood here that the “middle portion” of the handlebar transfer rod 100 and the front wheel transfer rod 200 refers to the portion between the two ends thereof.

Specifically, when storage is required, the locking member 300 is moved to the release position, and the handle transfer rod 100 is rotated to rotate toward the main frame 500, so that the locking member 300 is disengaged from the locking groove 520. At the same time, since the first connecting rod 600, the second connecting rod 700, the front wheel transfer rod 200 and the handle transfer rod 100 constitute a four-bar mechanism, the rotation of the handle transfer rod 100 can drive the front wheel transfer rod 200 to rotate through the four-bar mechanism, so that the front wheel transfer rod 200 also rotates toward the main frame 500, thereby realizing the folding and folding of the handle transfer rod 100 and the front wheel transfer rod 200 toward the main frame 500, and realizing the folding and folding of the child stroller 1. When the stroller needs to be unfolded, at least one of the front wheel transfer rod 200 and the handle transfer rod 100 is rotated in a direction away from the main frame 500, and the other of the front wheel transfer rod 200 and the handle transfer rod 100 is rotated in a direction away from the main frame 500 under the linkage action of the four-bar linkage mechanism, so that the front wheel transfer rod 200 and the handle transfer rod 100 are unfolded with each other until the locking member 300 is engaged in the locking groove 520, thereby limiting the relative rotation of the handle transfer rod 100 and the main frame 500, realizing the locking of the frame folding structure 10 of the stroller, thereby realizing the unfolding and positioning of the stroller 1.

According to the frame folding structure 10 of the child stroller of the embodiment of the utility model, the handlebar transfer rod 100 and the front wheel transfer rod 200 are pivotally connected via the main shaft 400, so that the handlebar transfer rod 100 and the front wheel transfer rod 200 can be folded, thereby reducing the space occupied by the child stroller 1 when not in use, and facilitating the storage of the child stroller.

Furthermore, by providing the first link 600 and the second link 700, a four-link transmission mechanism can be formed by utilizing the handlebar transfer rod 100, the front wheel transfer rod 200, the first link 600 and the second link 700. Thus, when any one of the front wheel transfer rod 200 and the handlebar transfer rod 100 is rotated, the other one will also rotate synchronously, thereby realizing synchronous unfolding or synchronous folding of the handlebar transfer rod 100 and the front wheel transfer rod 200. Compared with the technical solution of unfolding or folding each rod of the frame one by one in the related art, the folding and unfolding operation of the stroller 1 can be simplified, the use of the stroller 1 is facilitated, and the comfort of the user when using the stroller is improved.

In addition, by providing a locking member 300 on the handlebar transfer rod 100 and a locking groove 520 on the main frame 500, the relative position of the handlebar transfer rod 100 and the main frame 500 can be locked by the locking member 300. Due to the transmission of the four-bar linkage, the relative position of the front wheel transfer rod 200 and the main frame 500 can be locked synchronously, thereby achieving the overall locking of the frame folding structure 10 of the child stroller. When releasing, the frame folding structure 10 of the child stroller can be unlocked as a whole by simply moving the locking member 300 to the release position. Compared with the technical solution of unlocking each rod of the frame one by one in the related art, the folding and unfolding operations of the child stroller can be further simplified, and the use of the child stroller 1 can be further facilitated.

Therefore, the frame folding structure 10 of the child stroller according to the embodiment of the utility model has the advantages of being easy to store and operate.

The frame folding structure 10 of a child stroller according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.
