[0030] See also Figures 1 to 4 The present application provides a child stroller 1000 having an unfolded state and a folded state. The stroller includes a frame, a first seat 210, and a second seat 220 mounted on the frame. The frame includes two oppositely arranged side supports 100. The figure shows a front view of the child stroller 1000, i.e., a schematic structural diagram of one side support 100. For ease of description, the two side supports are oriented in the width direction.

[0031] Each side support 100 includes a front foot assembly 110, a rear foot assembly 120, and a handle assembly 130. Two of the three are hinged to each other, and the third is hinged to at least one of the other two. A connecting rod assembly is provided between the front foot assembly 110 and the rear foot assembly 120, and the connecting rod assembly includes one or more rods. A first adapter seat 141 is provided on the connecting rod assembly, and a second adapter seat 142 is provided on the handle assembly 130. The first seat 210 has a first adapter that is detachably connected to the first adapter seat 141, and the second seat 220 has a second adapter that is detachably connected to the second adapter seat 142. After being installed on the first adapter seat 141, the first seat 210 is located in front of the front foot assembly 110, that is, all or most of the first seat 210 is located in front of the front foot assembly 110, and the second adapter seat 142 is provided on the handle assembly 130.

[0032] The stroller of the present application realizes a two-person seating mode after installing the first and second seats. The second seat is higher than the first seat, which does not affect the field of view of the corresponding passenger. Removing one of the seats switches the stroller to a single-person seating mode. The installation position of the first adapter seat is different from that of the prior art, but the stroller still realizes both single and two-person seating modes.

[0033] In one embodiment, the connecting rod assembly has an extension portion 153 extending forward and beyond the forefoot assembly 110 . The first adapter seat 141 is disposed on the extension portion 153 , and the second adapter seat 142 is disposed on the handle assembly 130 .

[0034] In one embodiment, the second adapter seat 142 is movably mounted on the handle assembly 130, for example, the second adapter seat 142 is slidably mounted on the handle assembly 130. When switching to single-person mode, the first seat 210 is removed and the second adapter seat 142 is slid downward to lower the center of gravity of the entire vehicle and reduce the risk of rollover.

[0035] In one embodiment, the connecting rod assembly includes a two-folding rod, which includes a first connecting rod 151 hinged to the front foot assembly 110 and a second connecting rod 152 hinged to the rear foot assembly 120. The first connecting rod 151 and the second connecting rod 152 are hinged to each other, and the first connecting rod 151 extends forward to form an extension portion 153. When folding, the push handle assembly 130 rotates forward to approach the front foot assembly 110 or moves backward to approach the rear foot assembly 120, and the two-folding rod folds in half. The method for driving the two-folding rod to fold in half can be to connect a linkage rod between the push handle assembly 130 and the two-folding rod, and when folding, the linkage rod drives the two-folding rod to fold in half. Figure 1 and Figure 2 In the embodiment, the front foot assembly 110, the rear foot assembly 120 and the push handle assembly 130 are coaxially hinged.

[0036] Or as Figure 4 As shown, a structure of one of the side brackets 100 is provided, wherein the bottom of the handle assembly 130 is hinged to the top of the rear foot assembly 120, and the top of the front foot assembly 110 is hinged to the rear foot assembly 120. The stroller 1000 also includes a third connecting rod 190, which is hinged between the handle assembly 130 and the front foot assembly 110. The specific connection method can refer to the prior art. When the stroller 1000 of this embodiment is folded, the handle assembly 130 rotates close to the rear foot assembly 120, and the front foot assembly 110 is driven to rotate close to the rear foot assembly 120 by the third connecting rod 190, and accordingly, the two folding rods are folded in half. Among them, the first connecting rod 151 and the front foot assembly 110 are staggered in the width direction, and in the folded state, the extension 153 is close to the front foot assembly 110, and the front foot assembly 110 covers part or all of the extension 153.

[0037] Among them, the two-fold rod can be in a horizontal state in the unfolded state, that is, the angle between the two is equal to 180 degrees. When folding, it is necessary to apply an additional external force to the two-fold rod to fold it in the initial stage, such as lifting the two-fold rod with the instep, or by the aforementioned linkage rod; or, in another embodiment, during the unfolding and folding process of the two-fold rod, and in the unfolded state, the downward angle between the first link and the second link is always less than 180 degrees, eliminating the need for the aforementioned external force.

[0038] In one embodiment, the stroller 1000 further includes a flexible fabric cover 300 (shown as a dotted line in the figure) mounted between the two folding rods corresponding to the two side brackets 100 to form a storage space when unfolded. The flexible fabric cover 300 can be connected to the extension portion 153 to increase the storage space.

[0039] In order to improve the stability of the first seat, the first connecting rod may be structurally strengthened, for example, by increasing the material strength of the first connecting rod, or by providing a transverse member between the two first connecting rods to improve the structural strength.

[0040] See also Figure 5 The present application provides another structure of a side bracket 100, wherein the top of the rear foot assembly 120 is hinged to the handle assembly 130, and the handle assembly 130 extends downward to form an extension portion 191. The bottom of the extension portion 191 is hinged to the top of the front foot assembly 110. When folded, the handle assembly 130 rotates close to the rear foot assembly 120, and the connecting rod assembly includes a fourth connecting rod 160 hinged to the front foot assembly 110 and the rear foot assembly 120. The fourth connecting rod 160 extends toward the front side to form an extension portion 153, and the first adapter seat 141 is arranged on the extension portion 153.

[0041] The handle assembly 130, front leg assembly 110, fourth link 160, and rear leg assembly 120 form a foldable four-bar linkage. When the stroller 1000 is folded, the handle assembly 130 rotates rearward toward the rear leg assembly 120, and the fourth link 160 drives the front leg assembly 110 to rotate toward the rear leg assembly 120. The fourth link 160 and front leg assembly 110 are offset in the width direction. In the folded state, the extension 153 is adjacent to the front leg assembly 110, and the front leg assembly 110 partially or completely obscures the extension 153.

[0042] Among them, the child stroller 1000 also includes a flexible cloth cover 300 (dashed line part in the figure) hung between the two fourth connecting rods 160 to form a storage space in the unfolded state. The storage space is used for storing items. The flexible cloth cover 300 can be connected to the extension part 153 to increase the storage space.

[0043] In the stroller of the present application, the first adapter seat is arranged on the extension part of the connecting rod assembly. The structure is different from the existing technology, but it can still realize the double-seater mode of the stroller, and the connecting rod assembly can be used to hang a flexible cloth cover to serve as a storage basket. The flexible cloth cover is connected to the extension part to increase the storage space of the storage basket.

[0044] See also Figure 6 and Figure 7The present application provides another structure of a side stand 100, wherein the top of the rear foot assembly 120 is hinged to the handle assembly 130, and the bottom of the handle assembly 130 is hinged to the top of the front foot assembly 110. When folded, the handle assembly 130 rotates closer to the rear foot assembly 120. The connecting rod assembly includes a slide 180 slidably mounted on the front foot assembly 110 and the rear foot assembly 120, and a fifth connecting rod 170. When the slide 180 is slidably mounted on the front foot assembly 110, the ends of the fifth connecting rod 170 are hinged to the slide 180 and the rear foot assembly 120; when the slide 180 is slidably mounted on the rear foot assembly 120, the ends of the fifth connecting rod 180 are hinged to the slide 180 and the front foot assembly 110. The fifth connecting rod 180 is not strictly limited to a straight rod, but may also be a curved rod, and the fifth connecting rod 170 extends forward to form an extension portion 153, and the first adapter seat 141 is disposed on the extension portion 153.

[0045] The push handle assembly 130 , the front leg assembly 110 , the fifth link 170 and the rear leg assembly 120 form a foldable four-bar linkage.

[0046] The stroller 1000 further includes a flexible cloth cover 300 (shown as a dotted line in the figure) mounted between the two fifth links 170 to create a storage space when deployed. The flexible cloth cover 300 can be connected to the extension 153 to increase the storage space. The remaining structure is similar to the previous embodiment and will not be repeated here.

[0047] In another embodiment, the first adapter seat 141 has an extension portion 153, that is, the extension portion 153 is part of the first adapter seat 141. In this case, the connection position of the extension portion 153 and the connecting rod assembly is combined with the above embodiment:

[0048] The extension portion 153 is connected to the first connecting rod or the second connecting rod;

[0049] The extension portion 153 is connected to the fourth connecting rod;

[0050] The extension portion 153 is connected to the fifth link.

[0051] There is no strict limitation on the connection mode between the extension portion 153 and the connecting rod assembly, and the connection mode may be hinged or sliding fit.

[0052] The technical features of the above embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification. When technical features in different embodiments are reflected in the same figure, it can be regarded as that figure also discloses the combination examples of the various embodiments involved.

[0053] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art could make numerous variations and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
