[0028] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0029] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0031] An embodiment of this utility model provides a foldable outdoor stroller, such as... Figure 1-3As shown, the trolley includes two supports 110, a folding structure 200, a locking structure 300, and several foldable bags 120. Each of the two supports 110 has casters 130 at its bottom. The casters 130 reduce friction during movement, making the trolley easier to move. The casters 130 can be swivel casters or fixed casters. The bags 120 are positioned between the two supports 110 and are connected to the supports 110 and / or the folding structure 200. The bags 120 are used to hold items, and because they are foldable, they can also be folded away when the entire trolley is stored. The bags 120 can be cloth bags, paper bags, or other foldable bags.

[0032] The folding structure 200 is disposed between and connected to both supports 110. The folding structure 200 has switchable unfolded and folded states. Figure 1 As shown, when the folding structure 200 is in the unfolded state, the two supports 110 are far apart, the entire outdoor stroller is unfolded, and the user can use the outdoor stroller normally. Figure 3 As shown, when the folding structure 200 is in the folded state, the two supports 110 come close to each other, allowing the entire outdoor stroller to be folded up, reducing space occupation and making it easy to store and carry.

[0033] The locking structure 300 is connected to the folding structure 200 and is used to lock the folding structure 200 in the unfolded state or release the lock on the folding structure 200. When the locking structure 300 locks the folding structure 200 in the unfolded state, the folding structure 200 will not fold on its own, ensuring normal use of the outdoor stroller. After the locking structure 300 releases the lock on the folding structure 200, the folding structure 200 can be switched to the folded state, and the two brackets 110 come together, allowing the entire outdoor stroller to be folded up.

[0034] In some embodiments, as Figure 3-5 As shown, the folding structure 200 includes two linkage assemblies 210, which are respectively disposed on the front and rear sides of the bracket 110. Each linkage assembly 210 includes two support rods 211 and two connecting rods 212. The two support rods 211 are staggered to form an "X"-shaped structure. The lower ends of the two support rods 211 are rotatably connected to the two brackets 110, and the middle portions of the two support rods 211 are rotatably connected to each other. The two ends of one connecting rod 212 are rotatably connected to one bracket 110 and one support rod 211, respectively. The two ends of the other connecting rod 212 are rotatably connected to the other bracket 110 and the other support rod 211, respectively.

[0035] When the two support rods 211 of the same linkage assembly 210 rotate toward each other, the included angle between the two support rods 211 decreases, and the support rods 211 rotate relative to the bracket 110, causing the connecting rod 212 to rotate relative to the bracket 110. When the included angle between the two support rods 211 decreases to the minimum achievable angle, the folding structure 200 is in a folded state, and the two brackets 110 move closer to each other. Conversely, when the two support rods 211 of the same linkage assembly 210 rotate toward each other, the included angle between the two support rods 211 increases, and the support rods 211 rotate relative to the bracket 110, causing the connecting rod 212 to rotate relative to the bracket 110. When the included angle between the two support rods 211 increases to the maximum achievable angle, the folding structure 200 is in an unfolded state, and the two brackets 110 move away from each other.

[0036] Furthermore, the folding structure 200 also includes two synchronizing rods 220. Since there are two sets of linkage assemblies 210, the two support rods 211 rotatably connected to the same bracket 110 belong to different linkage assemblies 210. The upper ends of the support rods 211 included in the two linkage assemblies 210 rotatably connected to one bracket 110 are all connected to one of the synchronizing rods 220, and the upper ends of the support rods 211 included in the two linkage assemblies 210 rotatably connected to the other bracket 110 are all connected to the other synchronizing rod 220. The synchronizing rod 220 and the two support rods 211 connected to it form a U-shaped structure.

[0037] When the two support rods 211 of one of the linkage assemblies 210 rotate relative to each other, due to the presence of the synchronizing rod 220, the two support rods 211 of the other linkage assembly 210 will rotate relative to each other. The two linkage assemblies 210 can then move synchronously, allowing the front and rear sides of the two brackets 110 to move closer or further apart in sync, so as to unfold or fold the entire outdoor stroller more smoothly.

[0038] Based on the above embodiments, this embodiment provides an embodiment of a locking structure, such as... Figure 2 , Figure 4 and Figure 6 As shown, the locking structure 300 includes a top plate 310. One end of the top plate 310 is rotatably connected to one of the synchronizing rods 220, and the other end of the top plate 310 is detachably connected to another synchronizing rod 220. When the other end of the top plate 310 is connected to the other synchronizing rod 220, the top plate 310 and the two support rods 211 form a triangular arrangement, which restricts the relative rotation of the two support rods 211 of the linkage assembly 210, keeping the folding structure 200 in the unfolded state and making it difficult for it to fold on its own. When the other end of the top plate 310 is separated from the other synchronizing rod 220, the restriction between the two support rods 211 of the linkage assembly 210 is released, the two support rods 211 can rotate relative to each other, and the folding structure 200 can switch to the folded state.

[0039] Furthermore, the top plate 310 is provided with a slot 311 that matches the synchronizing rod 220. The synchronizing rod 220, which is detachably connected to the top plate 310, is snapped and fixed in the slot 311. The detachable connection between the top plate 310 and the synchronizing rod 220 is achieved by snapping and fixing, which is easy to operate and makes installation and disassembly more convenient.

[0040] In some embodiments, both synchronizing rods 220 are located above the two supports 110, and the top plate 310 is also located above the two supports 110. The top surface of the top plate 310 is not blocked by the supports 110. When the top plate 310 is connected to the synchronizing rods 220, the user can sit on the top plate 310 or place items on the top plate 310 to increase the functionality of the outdoor stroller.

[0041] Based on the above embodiments, this embodiment provides another embodiment of the locking structure, such as... Figure 2 and Figure 7 As shown, the locking structure 300 includes a locking hook 320, a hanging rod 330, and an elastic mechanism 340. The locking hook 320 and the hanging rod 330 are respectively mounted on the support rod 211 and the connecting rod 212, which are rotatably connected to each other. The locking hook 320 is rotatably connected to the support rod 211. After the locking hook 320 rotates relative to the support rod 211, it can hook onto the hanging rod 330 or detach from it. When the locking hook 320 hooks onto the hanging rod 330, it restricts the relative rotation of the support rod 211 and the connecting rod 212, thus preventing the support rod 211 from rotating, and the folding structure 200 remains in the unfolded state. When the locking hook 320 detaches from the hanging rod 330, the restriction on the relative rotation of the support rod 211 and the connecting rod 212 is released, allowing the support rod 211 to rotate, and the folding structure 200 can switch to the folded state. Meanwhile, the elastic mechanism 340 applies force to the locking hook 320 so that the locking hook 320 remains hooked on the hanging rod 330, and the folding structure 200 can remain in the unfolded state and will not fold easily.

[0042] In this embodiment, the elastic mechanism 340 can be a torsion spring, which is sleeved on the rotating shaft of the locking hook 320 and the support rod 211, and the two rotating arms of the torsion spring respectively abut against the locking hook 320 and the support rod 211.

[0043] The above provides two embodiments of the locking structure. One of the two embodiments can be used, or both embodiments can be used simultaneously, resulting in a better locking effect on the folding structure 200.

[0044] In some embodiments, as Figure 1 and Figure 2As shown, the bag body 120 is connected to two supports 110 on each side. When the folding structure 200 is in the unfolded state, the two supports 110 are far apart, allowing the bag body 120 to be opened, so that the user can use the bag body 120 to carry items. When the folding structure 200 is in the folded state, the two supports 110 are close together, and the bag body 120 is folded up accordingly, saving space.

[0045] In other embodiments, the front and rear sides of the bag are connected to two linkage assemblies, respectively. When the folding structure is in the unfolded state, the bag can be normally loaded with items. When the folding structure is in the folded state, the two supports press against each other, causing the bag to fold.

[0046] In some embodiments, as Figure 1-3 As shown, the foldable outdoor stroller also includes a handle 400, which is connected to the bracket 110 and / or the folding structure 200. Users can push the entire outdoor stroller by holding the handle 400, making it more convenient to use.

[0047] Specifically, the handle 400 can be centrally located, and the rotation axes of the two support rods can be connected to the handle 400 so that the handle 400 does not affect the rotation of the support rods.

[0048] In some embodiments, the bottom of the bracket 110 is also provided with a support foot 140, which can provide support for the entire outdoor stroller and prevent the outdoor stroller from tipping over.
