The present disclosure relates to a child stroller.
Child strollers are commonly used in families with infants and provide great convenience to travel. In general, the child stroller can be unfolded or folded. The child stroller can carry the infant in the unfolded state, and occupy limited space in the folded state.
In order to stably keep the folded child strollers in the folded state, some child strollers are equipped with folding hooks and locking portions for a specific purpose. The folding hook and the locking portion are mounted on two foldable brackets of the frame of the child stroller, respectively, and the folding hook is provided with a locking recess for accommodating the locking portion. When the frame of the child stroller is in the folded state, the locking portion is engaged with the locking recess of the folding hook, thereby locking relative positions of the two brackets of the frame, which can effectively prevent the folded child stroller from being accidentally unfolded during movement. For convenience during engagement and disengagement of the folding hook and the locking recess, the folding hook is pivotally mounted on one of the brackets of the frame in general, and the bracket is further provided with a pusher and a spring. The spring is used to keep the folding hook at a connection position where the folding hook can be engaged with the locking portion. When stressed, the pusher can push the folding hook to rotate against force of the springs, thus disengaging the folding hook from the locking portion.
The present disclosure aims to provide a child stroller with a simple structure and multiple functions. The child stroller can be locked in a folded state when folded, and can be used in cooperation with an additional child carrier when unfolded.
The present disclosure discloses a child stroller. A frame of the child stroller may include a first bracket and a second bracket that are foldable. The first bracket can be provided with an engaging member, the engaging member includes a first engaging portion and a second engaging portion, and the first engaging portion is configured to be detachably engaged with a child carrier. The second bracket may be provided with a locking portion. When the first bracket and the second bracket are in a folded state, the locking portion and the second engaging portion are detachably engaged with each other to lock the first bracket and the second bracket in the folded state.
Further, the locking portion may include a locking stud.
Further, a first end of the engaging member may sleeve the first bracket and may be fixed by a hinge pin, and the first engaging portion and/or the second engaging portion may be arranged near a second end of the engaging member.
Further, the first bracket may be a backrest frame, and the second bracket may be a handle frame; and the frame may further include a front wheel support, a rear wheel support and a connection frame, wherein an upper end of the rear wheel support may be provided with a pivotal portion, an upper end of the front wheel support may be pivotally connected to a first connection portion of the pivotal portion, a lower end of the connection frame may be pivotally connected to a second connection portion of the pivotal portion, an upper end of the connection frame may be pivotally connected to a first pivotal connection portion of the second bracket, the first bracket may be pivotally connected to the rear wheel support via a second pivotal connection portion, and an upper end of the first bracket may be pivotally connected to a lower end of the second bracket.
Further, the child stroller may include a seat portion mounted on the frame; and/or the child carrier may be a car seat or a carry-cot.
Further, the first engaging portion may include a first recess and the second engaging portion may include a second recess.
Further, the first recess may be arranged at a first side of the engaging member, and the second recess may be arranged at a second side of the engaging member, the first side and the second side facing away from each other.
Further, the second side of the engaging member may be provided with a protrusion portion and a guide slope connected to the protrusion portion, the second recess may be formed in the protrusion portion, and the locking portion may be configured to be engaged into the second recess via the guide slope.
Further, the child carrier may be provided with an elastically retractable engaging block configured to be engaged with the first recess.
Further, the engaging block may be provided with a mounting slope, and a depth of an upper portion of the first recess may be smaller than a depth of a lower portion of the first recess.
According to the child stroller provided in the present disclosure, by arranging the first engaging portion and the second engaging portion on the engaging member, the engaging member may be detachably engaged with the child carrier via the first engaging portion when the frame is unfolded, and may be detachably engaged with the locking portion via the second engaging portion when the frame is folded, such that the engaging member may be used as a folding hook, and the child stroller requires no additional folding hook, thus simplifying the structure of the frame, reducing cost of the frame, and improving an appearance design of the frame advantageously.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Embodiments of the disclosure are described more fully hereinafter with reference to the accompanying drawings. The various embodiments of the disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Elements that are identified using the same or similar reference characters refer to the same or similar elements.
It should be noted that positional terms such as “upper”, “lower”, “front” and “rear” herein are explained with reference to the unfolded state of the frame. These positional terms are merely used to make description of the present disclosure clearer, and are not used to improperly limit the protection scope of the present disclosure.

According to the embodiments of the present disclosure, by arranging the first engaging portion 21 and the second engaging portion 22 on the engaging member 2, the engaging member 2 can be detachably engaged with the child carrier 5 via the first engaging portion 21 when the frame is unfolded, and can be detachably engaged with the locking portion 4 via the second engaging portion 22 when the frame is folded, such that the engaging member 2 may be used as a folding hook. As such, the child stroller requires no additional folding hook, thus simplifying the structure of the frame, reducing cost of the frame, and improving appearance design of the frame advantageously.
