[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0025] It should be noted that when a component is referred to as being "connected" with another component, it can be directly connected with the other component or there can be intervening components. When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component or there can be intervening components.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] In the present application, the terms "first", "second", etc. are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, order of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0028] First, for the convenience of description, "end" in the text represents the end point of the structure or a certain point or a certain area in the direction or a specific structure connected to the point or the area.

[0029] For the prior art frame and the connecting position of the handrail and the frame, the connecting position is higher than the hinge point of the handlebar and the front leg, that is, generally in the middle of the seat in the height direction, so that the connecting position is more obvious, and the appearance of the vehicle body is not simple enough.

[0030] Referring to Figures 1-3 The present application provides a stroller 1000 having opposite unfolded and folded states. The stroller 1000 comprises two opposite side frames, only one of which is shown in the figure, and the side frame comprises a handlebar assembly 110, a front leg assembly 120, a rear leg assembly 130 and a first connecting rod 140, wherein the above four constitute a foldable four-bar linkage mechanism, and the bottom of the front leg assembly 120 and the rear leg assembly 130 is provided with wheels.

[0031] The top of the front leg assembly 120 and the bottom of the handlebar assembly 110 are hinged at a first hinge point 210, the top of the rear leg assembly 130 is hinged to the handlebar assembly 110, and the two ends of the first link 140 are hinged to the front leg assembly 120 and the rear leg assembly 130 respectively. When folding, the handlebar assembly 110 is turned to close to the rear leg assembly 130, and the front leg assembly 120 is turned to close to the rear leg assembly 130 under the pulling of the first link 140. The unfolding movement is that the handlebar assembly 110 is turned away from the rear leg assembly 130, and the first link 140 drives the front leg assembly 120 to move away from the rear leg assembly 130. The two front leg assemblies 120 can be two independent groups spaced from each other, or connected at the bottom. The handlebar assembly 110 can be two independent groups spaced from each other, or connected at the top.

[0032] The child stroller 1000 further comprises a safety assembly 310 and a second link 320, wherein the safety assembly 310 extends in the width direction (i.e. the direction of the two side frames), and the two sides thereof are hinged to the front leg assembly 120 and / or the handlebar assembly 110. The two ends of the second link 320 are hinged to the safety assembly 310 and the first link 140 respectively. When folding the frame, the first link 140 drives the second link 320 to move to pull the safety assembly 310 to turn to close to the front leg assembly 120. When unfolding, the first link 140 drives the second link 320 to move to push the safety assembly 310 to turn away from the front leg assembly 120.

[0033] In the child stroller of the present application, the safety assembly is hinged to one of the front leg assembly, the handlebar assembly, or the first hinge point, which is different from the existing structure, but also achieves that the safety assembly can be folded or unfolded with the side frame.

[0034] In an embodiment, the safety assembly 310 can be a handrail or a tray, and the handrail is a U-shaped rod.

[0035] In the description, the safety assembly 310 is hinged to the first hinge point 210 as an example, but it is not limited to this. The two sides of the safety assembly 310 can also be hinged to the front leg assembly 120 or the handlebar assembly 110.

[0036] In a preferred embodiment, the two side ends of the safety assembly 310 are hinged to the first hinge point 210, so that the overall appearance of the child stroller is more simple, and the end is a connecting end, and the opposite end is a fixed end. The front leg assembly 120 and the second link 320 are cross-connected.

[0037] In order to further make the structure of the stroller body more compact and beautiful, in some embodiments, the second link 320 and the safety assembly 310 are hinged to a second hinge point 220, and the second hinge point 220 is arranged more adjacent to the first hinge point 210 than the fixed end of the safety assembly.

[0038] The second connecting rod 320 and the front leg assembly 120 are hinged at a third hinge point 230, which is arranged more proximally to the first hinge point 210 than the bottom end of the front leg assembly 120, and the second connecting rod 320 and the first connecting rod 140 are hinged at a fourth hinge point 240, which is arranged proximally to the third hinge point 230.

[0039] In an embodiment, the handle assembly 110, the front leg assembly 120 and the rear leg assembly 130 are coplanar, and the side rod 311 is arranged at the inner side or the outer side of the front leg assembly 120. In the unfolded state, the handle assembly 110 and the front leg assembly 120 are collinear, and in the unfolded state, the four connecting rods form a triangular structure, which improves the structural stability.

[0040] The rear leg assembly 130 is hinged with the handle assembly 110 at a fifth hinge point 250, which is arranged near the middle of the handle assembly 110, preferably near the first hinge point 210.

[0041] In an embodiment, a locking mechanism is arranged on the side frame to keep the stroller in the unfolded state. For example, the locking mechanism can be arranged at the first hinge point or other hinge points.

[0042] The stroller of the present application has a different structure of the stroller body than the prior art, but achieves the same technical effect, i.e. the safety assembly can be folded or unfolded with the frame.

[0043] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered as within the scope of the present application. When the technical features of different embodiments are embodied in the same drawing, it can be considered that the drawing also discloses the combination of the embodiments involved.

[0044] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application.
