DETAILED DESCRIPTION OF THE INVENTION

[0026] Aspects of the present disclosure are best understood from the following detailed description when read with the accompanying figures. It is evident that the described embodiments are merely a part of the present disclosure's embodiments and not all of them. Based on the embodiments of this disclosure, all other embodiments that can be obtained by ordinary skilled persons in the art without any creative work fall within the scope of this disclosure.

[0027] As shown in FIGS. 1 to 8, a children's stroller with easy disassembly and assembly features is provided. The stroller includes a frame 10, a wheel module 20 is disposed below the frame 10, and a stroller module 30 is disposed above the frame 10. The frame 10 moves through applying force to the stroller module 30 to move in corporation with the wheel module 20. The frame 10 includes a front support rod 11, a rear support rod 12, a first side frame 13, and a second side frame 14. The first side frame 13 and the second side frame 14 are parallel to each other and spaced apart from each other. Each upper ends of the first side frame 13 and the second side frame 14 has a connecting buckle 144, and the connecting buckles 144 on the same ends of the first side frame 13 and the second side frame 14 correspond to each other. Each of the ends of the front support rod 11 and the rear support rod 12 has a connecting groove 123 corresponding to the connecting buckle 144. The front support rod 11 and the rear support rod 12 are detachably disposed on the front side and the rear side of the first side frame 13 and the second side frame 14, respectively, through the corporation of the connecting groove 123 and the connecting buckle 144. A plurality of auxiliary brackets 17 are connected to and below the first side frame 13 and the second side frame 14. The auxiliary brackets 17 are transversely disposed between the first side frame 13 and the second side frame 14. The auxiliary brackets 17 are spaced apart from each other to form an accommodating space having an upward-facing opening on the frame 10. An auxiliary clamping buckle 15 and an auxiliary item-carrying frame 16 are disposed on the first side frame 13 and the second side frame 14. The auxiliary clamping buckle 15 is coaxially aligned with the connecting buckle 144 in a vertical direction. The auxiliary clamping buckle 15 is below the connecting buckle 144. The auxiliary item-carrying frame 16 is detachably connected to the auxiliary clamping buckle 15. When the auxiliary item-carrying frame 16 connects to the auxiliary clamping buckle 15, the auxiliary item-carrying frame 16 extends to the front side and/or the rear side of the frame 10 to form an auxiliary item-carrying space connected to the accommodating space. The first side frame 13 and the second side frame 14 are arranged in parallel to each other when assembling the frame 10. Afterwards, the front ends and the rear ends of the first side frame 13 and the second side frame 14 are connected to the front support rod 11 and the rear support rod 12 through the corporation of the connecting buckle 144 and the connecting groove 123. A plurality of auxiliary bracket 17 are connected to and below the first side frame 13 and the second side frame 14, and then the accommodating space with an upward-facing opening on the frame 10 is formed with cloth wrapping. The child is placed in the accommodating space when using the frame 10, and the child is protected by the frame 10 to prevent from falling out from the frame 10. Parents can move the frame 10 by applying a certain amount of pushing or pulling force to the stroller module 30, the pushing or pulling force are transmitted to the wheel module 20, and the wheel module 20 is rotated to drive the frame 10. In everyday scenarios, such as when carrying a child while shopping at a supermarket, managing an additional shopping cart or carrying a shopping basket may result in an excessive load. In this situation, the front support rod 11 or the rear support rod 12 may be disassembled to form a front opening or a rear opening on the accommodating space of the frame 10. Afterwards, the auxiliary item-carrying frame 16 is connected to the front side or the rear side of the frame 10 to form an auxiliary item-carrying space extending to the front side or the rear side on the frame 10. The shopping basket can be placed on the auxiliary item-carrying space to achieve a multifunctional use of the stroller. Similarly, it is common to carry camping supplies such as tents and food when taking children to the park to increase the time they spend in nature. However, when using a stroller and simultaneously and having to carry additional supplies, it can result in an excessive load that makes it difficult to care for the child. This greatly reduces the willingness of parents to take their children outdoors. The aforementioned method can also extend an auxiliary item-carrying space outward from the frame 10. On one hand, the auxiliary item-carrying space can meet the demand for carrying items on the stroller. On the other hand, the auxiliary item-carrying space does not occupy the entire accommodating space of the stroller. This allows for simultaneously accommodating both items and children, thereby enhancing the convenience of using the stroller. Furthermore, shapes and structures of the connecting buckle 144 and the auxiliary clamping buckle 15 are identical, so the front support rod 11 or the rear support rod 12 can be disassembled from the connecting buckle 144 and then connected to the auxiliary clamping buckle 15. As a result, the height of the front support rod 11 and/or the rear support rod 12 on the frame 10 may be reduced by half to make the stroller adaptable to various application scenarios and fulfilling parent-child interaction.

[0028] Both of the front support rod 11 and the rear support rod 12 have a rod body 121 and connectors 122 on both ends of the rod body 121. A connecting groove 123 is formed on an external side of the connector 122. A connecting guide recess is provided on a side of the connecting buckle 144. A connecting opening is formed below the connector 122, and the connecting opening connects to the connecting groove 123. The connector 122 is fitted onto the connecting buckle 144 from top to bottom through the connection guide recess via the connecting opening formed on the connecting groove 123. In this embodiment, connectors 122 are provided at both ends of the rod body 121. The connecting groove 123 are formed on external sides of the connector 122. By providing clamping openings above and below the connecting groove 123, the connector 122 can be fitted onto the connecting buckle 144 from the top to bottom to allow the front support rod 11 and the connector 122 be connected to the first side frame 13 and the second side frame 14. The connecting guide recess on the side of the connecting buckle 144 improves the smoothness of connecting or disconnecting the connector 122 to enhance the user experience.

[0029] An engaging groove 145 is formed at a side of the connecting buckle 144. An engaging block 124 which matches the engaging groove 145 is disposed in the connecting groove 123. An engaging transmission element 125 is fitted on the rod body 121. The engaging transmission element 125 is transmissively connected to the engaging block 124. The engaging transmission element 125 drives the engaging block 124 to connect to the engaging groove 145 or to detach from the engaging groove 145. In this embodiment, the front support rod 11 or the rear support rod 12 is engaged through the cooperation of the engaging block 124 and the engaging groove 145. By using the engaging transmission element 125 to move the engaging block 124, the connection or detachment between the engaging block 124 and the engaging groove 145 is achieved, so the front support rod 11 or the rear support rod 12 may be fixed or disassembled.

[0030] The auxiliary item-carrying frame 16 includes an item-carrying support rod 161 and connecting blocks 162 disposed at both ends of the item-carrying support rod 161.

The support portion 1612 is disposed on the side of the bending portion 16112 that extends outwardly. An installing groove 164 is provided on the connecting block 162, and the installing groove 164 has an opening facing upwardly. The installing portion 16111 is disposed in the installing groove 164 and connected to the installing block 162 by external screws. In this embodiment, the connecting portion 1611 and the support portion 1612 are integrally formed as one piece to make the item-carrying support rod 161. The connecting portion 1611 includes the installing portion 16111 and the bending portion 16112. The connecting portion 1611 is vertically inserted into the installing groove 164 on the connecting block 162, and then the installing portion 16111 is affixed in the installing groove 164 by external screws. The bending portion 16112 is bent to the front side or the rear side of the installing portion 16111 to affix the position and the orientation of the support portion 1612, thus connecting with the accommodating space while extending the auxiliary item-carrying space on the frame 10.

[0032] Both of the first side frame 13 and the second side frame 14 have two fixed brackets 141 and a movable bracket 142. The movable bracket 142 is disposed between the two fixed brackets 141. Sides of the two fixed brackets 141 on the side facing each other has assembly portions 143, and two ends of the movable bracket 142 are pivoted to the assembly portions 143. The two fixed brackets 141 on the same side are disposed opposite each other. A connecting buckle 144 is disposed on one side adjacent to the assembly portion 143 and positioned on the side of the two fixed brackets 141 opposite each other. In this embodiment, the first side frame 13 or the second side frame 14 is formed by disposing a movable bracket 142 between the two fixed brackets 141 to allow the movable bracket 142 cooperate with the fixed bracket 141, thus enabling the frame 10 to fold.

[0033] The movable bracket 142 has an H shape and includes a main support rod 1421. An upper movable bracket 1422(142) is disposed over the main support rod 1421, and a lower movable bracket 1423(142) is disposed below the main support rod 1421.

When the frame 10 needs to be moved for an extended period, the wheel module 20 can be assembled with the frame 10 for mobility. When the frame 10 does not need to be moved for an extended period, the wheel module 20 can be removed to allow the frame 10 to rest directly on the ground and converted into a child's bed, thereby providing flexibility based on usage needs.

[0037] Additionally, a canopy lifting lock 18 is disposed on the fixed bracket 141 of the frame 10. A canopy bracket 19 can be installed over the frame 10 by the canopy lifting lock 18. A canopy can be installed by the canopy bracket 19. The canopy bracket 19 can be shrink by the canopy lifting lock 18 to adjust the height of the canopy bracket 19 in the vertical direction.
