[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0034] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] In this application, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity or order of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] Refer to Figures 1 to 12 , this application provides a baby stroller 1000, which has an unfolded state and a folded state, and includes two side brackets 100 arranged oppositely and a seat 200 connected between the two side brackets 100. The side bracket 100 includes a front foot assembly 110, a rear foot assembly 120, a handle assembly 130 and a first link 140. The connection method of the side bracket 100:

[0038] The handle assembly 130 is rotationally matched with the rear foot assembly 120, and the front foot assembly 110 and the rear foot assembly 120 are rotationally matched. The specific connection method includes but is not limited to that the handle assembly 130 and the rear foot assembly 120 of this application are hinged around a first axis 151, and the front foot assembly 110 and the rear foot assembly 120 are hinged around a second axis 152, where the first axis 151 and the second axis 152 are not coaxial. When folding, the handle assembly 130 rotates and closes to the rear foot assembly 120, and drives the front foot assembly 110 to close to the rear foot assembly 120 through the first link 140.

[0039] The seat 200 includes a seat 210 for supporting the child's buttocks and a second link 220. The seat 210 is rotatably engaged with the rear foot assembly 120. Two ends of the second link 220 are respectively hinged to the seat 210 and the front foot assembly 110. When folding or unfolding, the front foot assembly 110 drives the seat 210 to rotate closer to or away from the rear foot assembly 120 through the second link 220.

[0040] The baby stroller of the present application has a simpler structure compared with the existing one, and the seat can still be folded and unfolded synchronously with the side brackets, which is convenient to operate.

[0041] In one embodiment, the rear foot assembly 120, the handle assembly 130 and the front foot assembly 110 meet at a rotating joint 160. Both sides of the rear part of the seat 210 are provided with connecting seats 211 hinged to the rotating joint 160. The connecting seats 211 are arranged at the rear part of the seat 210, so that in the folded state, the rear part of the seat 210 does not protrude from the side bracket 100, that is, after folding, the seat 210 does not protrude from the top of the side bracket, reducing the folding volume.

[0042] The rotating joint 160 includes a first joint element 161 fixedly connected to the rear foot assembly 120 and a second joint element 162 fixedly connected to the handle assembly 130. The first joint element 161 and the second joint element 162 are rotatably engaged around a first axis 151. The connecting seat 211 is hinged to the rotating joint 160 around the first axis 151 and is hidden by the rotating joint 160, that is, when observing along the first axis 151, the connecting seat 211 is blocked by the rotating joint 160.

[0043] As Figures 6 to 9 or Figures 10 to 12 shown, the first joint element 161 and the second joint element 162 are composed of one or two iron sheets. The rotating joint 160 includes a hollow housing 165. The housing 165 is fixedly connected to the rear foot assembly 120, and the first joint element 161, the second joint element 162 and the first link 140 are located inside the housing 165. The first joint element 161 includes a disc-shaped body 163 and an extension 164 protruding radially (relative to the first axis 151) from the body 163. The front foot assembly 110 is hinged to the extension 164. When folding, the front foot assembly 110 can be closer to the rear foot assembly 120.

[0044] The seat 210 can be plate-shaped or a frame structure as Figure 1 shown, which extends along a first plane. The connecting seat 211 extends along a second plane. The first plane and the second plane are perpendicular to each other. The seat 200 further includes a cloth cover connected to the seat 210 and the handle assembly 130. When the baby stroller 1000 is in the unfolded state, the cloth cover forms a backrest. When folding, the cloth cover is easy to fold and store.

[0045] One end of the second link 220 is hinged to the connecting seat 211, and in the unfolded state, the second link 220 is located below the seat 210, providing higher safety. One end of the first link 140 is hinged to the handle assembly 130 with the hinge point eccentrically arranged with respect to the first axis 151, and the other end is hinged to the front foot assembly 110 with the hinge point eccentrically arranged with respect to the second axis 152.

[0046] In one embodiment, the handle assembly 130 includes a lower handle 131 rotatably engaged with the rear foot assembly 120, and an upper handle 132. The upper handle 132 is foldable relative to the lower handle 131. In the folded state, the length of the handle assembly 130 is less than or equal to that of the rear foot assembly 120, resulting in a smaller folding volume. The baby stroller 1000 further includes a locking mechanism for the side brackets 100 in the unfolded state, and the upper handle 132 is folded relative to the lower handle 131 to unlock the locking mechanism.

[0047] The front ends of the front foot assemblies 100 of the two side brackets 100 are connected, and the upper ends of the handle assemblies 130 of the two side brackets 100 are connected. Wheels for movement are installed at the bottoms of the front foot assembly 110 and the rear foot assembly 120.

[0048] The baby stroller of the present application has a simpler structure than the existing baby strollers. When folding and unfolding, the seat can still be folded or unfolded synchronously with the side brackets, facilitating operation.

[0049] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the respective embodiments involved.

[0050] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
