[0049] 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 herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] First, for ease of description, the term "end" in the text refers to the endpoint of the structure, or a point or region in that lateral direction, or a specific structure connected to that point or region.

[0052] See Figures 1-4 This application provides a handcart with an extension device (hereinafter referred to as handcart 1000), wherein the handcart 1000 has a length direction and a width direction. Figure 1 Show the perspective of the handcart projected along its width.

[0053] The stroller 1000 includes a frame structure 10, an adapter seat 400, and a locking mechanism. The frame structure 10 has an open-top accommodating space, preferably with a lining 600 inside so that the accommodating space can be used for storing items or carrying children. The adapter seat 400 is slidably mounted on the frame structure 10. An extension device is detachably mounted on the adapter seat 400 and located above the accommodating space. The extension device allows part of itself to be placed within the accommodating space, depending on the type of extension device, such as a child seat (ordinary child seat or car seat), tray, sunshade, sleeping box, etc. Some special extension devices also have mounting brackets that are detachably mounted to the adapter seat.

[0054] In this embodiment, the trolley can be equipped with one or more extension devices. The user can adjust the adapter 400 to the corresponding position according to different extension devices, and then lock the adapter 400 in place using locking components. The assembly method for different extension devices is the same for the trolley, reducing the installation difficulty for the user. The trolley does not need to consider the specific structure for connecting with different extension devices; it only needs to consider the connection structure between the adapter and the upper frame, thus simplifying the frame structure.

[0055] The number of adapters 400 is either odd or even, and the expansion device includes an adapter 410 that is detachably connected to the adapter 400. For example... Figure 4 As shown, the tray 510 and the awning 520 are installed simultaneously; or as shown Figure 3 The diagram shows two child seats 530 installed. The tray 510 and child seats 530, along with other extension equipment, span the frame structure 10, with corresponding adapter seats 400 arranged in pairs, each pair of adapter seats 400 being arranged opposite each other along the width and / or length direction.

[0056] The sliding direction of the adapter 400 is determined by the extension direction of the frame structure 10, such as sliding horizontally or tilting. The frame structure 10 includes a base support 100, an upper frame 200, and side supports 300. The base support has wheels 700 at its bottom. The upper frame 200 is positioned above the base support 100 and slides with the adapter 400. The upper frame 200 can be tilted or horizontal. The side supports 300 connect the base support 100 and the upper frame 200. In a preferred embodiment, the upper frame 200 is horizontally positioned, allowing the adapter 400 to slide horizontally. Specifically, the upper frame 200 includes a pair of opposing rods 210, on which the adapter 400 is slidably mounted.

[0057] In one embodiment, a guide rail is fixedly disposed on the upper frame 200, and the adapter 400 is slidably mounted on the guide rail. Depending on the specific structure of the upper frame 200, for example, the upper frame 200 can be as follows: Figure 2The diagram shows an integrated, enclosed structure. Preferably, the adapter 400 can slide to any position of the upper frame 200, or the upper frame 200 has a multi-segment structure, with the adapter 400 mounted on at least one segment.

[0058] In one embodiment, the trolley 1000 also includes an unlocking component for unlocking the locking component, although the locking component itself can also serve as an unlocking component.

[0059] In one embodiment, the frame structure 10 is foldable, for example, the upper frame 200 and the bottom support 100 are a two-section structure; or as... Figure 3 As shown, the side support 300 is a foldable structure. When the trolley is folded, the upper frame 200 moves closer to the bottom support 100, preferably parallel to it. The figure illustrates the structure of one type of side support 300. The side support 300 includes a two-section rod, a third connecting rod 330, and a support rod 340. The two-section rod includes a first connecting rod 310 and a second connecting rod 320 that are hinged to each other. One end of the first connecting rod 310 is hinged to the upper frame 200, one end of the second connecting rod 320 is hinged to the bottom support 100, and the third connecting rod 330 is hinged to the first connecting rod 310. Both ends of the support rod 340 are hinged to the third connecting rod 330 and the upper frame 200, respectively. The side support 300 can also adopt other existing structures.

[0060] The handcart 1000 also includes a handlebar 350. In the figure, the first link 310 extends upward and the extended part serves as the handlebar 350.

[0061] In another embodiment, the adapter 400 is detachably connected to the frame structure 10. Depending on the expansion device, the adapter 400 can be detached from one mounting position and moved and fixed to another mounting position, or the number of adapters 400 can be increased or decreased. There are multiple adapters 400; some adapters 400 can be fixed relative to the upper frame 200, while others can move relative to the upper frame 200 to switch positions.

[0062] This application also provides a handcart 1000 with an extension device, including a frame structure 10, an adapter 400, a first extension device, and a second extension device. The adapter 400 is slidably mounted on the frame structure, and the extension device is detachably mounted on the adapter 400 and located above the accommodating space. The frame structure can refer to the foregoing embodiment and has a first mounting position and a second mounting position for positioning the first extension device, and a third mounting position for positioning the second extension device.

In the second usage mode, the first extension device is positioned in the second mounting position, and the second extension device is removed from the third mounting position. For example, both the first and second extension devices are child seats 530. Figure 5 As shown, the stroller is equipped with two child seats 530, or as... Figure 6 or Figure 7 As shown, the stroller only has one child seat installed (530). Figure 6 and Figure 7 The orientation of the child seat 530 can be adjusted as needed. Additional features include a sleeping box, tray, and sunshade.

[0064] The trolley 1000 includes multiple adapter seats 400. A first expansion device and a second expansion device are mounted on the frame structure 10 via the adapter seats 400, wherein at least one adapter seat 400 can slide to switch between mounting positions. Specifically, the adapter seat 400 can be switched between:

[0065] Between the first mounting position and the second mounting position;

[0066] Or between the first mounting position and the third mounting position;

[0067] Or between the second mounting position and the third mounting position;

[0068] Or between three mounting positions.

[0069] Other structures of the adapter 400 can be referred to in the foregoing embodiments. For example, the trolley 1000 also includes a locking element for locking the adapter 400 in the corresponding position, as described in the foregoing embodiments.

[0070] In one embodiment, the trolley also includes a lining 600 disposed within the frame structure.
