Description

Technical Field

[0001] This application relates to the field of toy carts, and more particularly to a toy cart that can be quickly assembled. Background Technology

[0002] Toy carts are bulky, making them difficult to transport and store. Therefore, this paper proposes a toy cart that can be quickly assembled and disassembled, improving the convenience of transportation and storage.

[0003] Traditional toy carts with a fixed structure are bulky and non-disassembly-based, causing numerous inconveniences during transportation and storage. This one-piece structure not only occupies a lot of storage space and increases logistics costs, but also makes it difficult to flexibly adjust to actual space conditions when used at home.

[0004] Especially when children's toys need to be used in different scenarios frequently, fixed-structure strollers cannot meet diverse usage needs and are not convenient for daily storage and organization. Therefore, there is a need for a toy stroller that can be quickly assembled and is easy to transport and store. Utility Model Content

[0005] To improve the convenience of transporting and storing toy carts, this application provides a toy cart that can be quickly assembled.

[0006] The toy cart that can be quickly assembled according to this application adopts the following technical solution: A toy cart that can be quickly assembled includes a flexible frame made of a flexible material, a frame body made of a rigid material, and a pulley assembly. The flexible frame is detachably connected to the frame body. The frame body includes a base frame, a slant frame, and a movable frame. The bottom end of the slant frame is hinged to the front end of the base frame, and the top end of the movable frame is hinged to the top end of the slant frame. A sliding member is hinged to the bottom end of the movable frame, and the sliding member is slidably connected to the base frame along the length direction of the base frame. The base frame has a connection point. When the slant frame is connected to the base frame at the connection point, the frame body is in the form of a cart. The pulley assembly is detachably connected to the frame body.

[0007] By adopting the above technical solution, when storage is required, the fixing point between the inclined frame and the base frame is released, and the movable frame is pushed to move the sliding component forward along the base frame, causing the inclined frame to fold towards the base frame. The flexible frame can be rolled up and compressed after being removed from the frame body, and the pulley assembly can be stored separately after separation. In use, the movable frame is pushed back to unfold the frame, the inclined frame is fixed to the connection point, the pulley assembly is installed, and the flexible frame is connected. Through the cooperation of the hinge structure and the sliding component, the frame body can switch between a folded state and an unfolded state, and the overall volume can be compressed in conjunction with the detachable parts.

[0008] The frame can be completely disassembled into three independent components—the base frame, the slant frame, and the movable frame—using a flexible frame that can be rolled up for storage, reducing the overall size. The independently detachable pulley assembly design avoids interference with storage space caused by the wheel and axle structure.

[0009] This allows for quick disassembly and independent storage of each component of the toy stroller. During transport, it can be packed into flat boxes, and for convenient storage in small spaces at home. The frame folds into a compact structure, and the flexible material's deformation properties effectively solve the problem of traditional strollers being too bulky. The detachable connection structure ensures stability while improving transportation and storage efficiency.

[0010] Optionally, the frame body further includes a handle frame, which is movably connected to the top of the inclined frame, and the distance between the end of the handle frame away from the inclined frame and the inclined frame is adjustable.

[0011] By adopting the above technical solution, the handle can be folded down to its minimum size when stored, reducing transportation and storage costs; when in use, it can be quickly unfolded and fixed to a suitable length to meet the operating needs of users of different ages and improve the flexibility of toy cart use.

[0012] Optionally, the handle frame is hinged to the inclined frame.

[0013] Optionally, the handle bracket can be detachably connected to the inclined frame.

[0014] Optionally, the base frame is provided with a positioning element at the connection point, the positioning element being used to fix the inclined frame and the base frame to each other at the connection point.

[0015] Optionally, the base frame includes a detachable rod that extends along the width of the base frame; the rear end of the base frame has a through hole for the detachable rod to pass through; the pulley block includes a pair of rear wheels that are detachably connected to both ends of the detachable rod.

[0016] By adopting the above technical solution, the rear wheel assembly is made into an independent module through the cooperation of the detachable rod and the through hole. During disassembly, only the detachable rod needs to be removed to separate all the rear wheels. At the same time, the through hole provides axial restraint for the detachable rod to prevent misalignment of the components during disassembly.

[0017] Optionally, the pulley assembly may further include a pair of front wheels, both of which are detachably connected to the front end of the base frame.

[0018] By adopting the above technical solution and using a detachable connection design, the front wheels can be independently disassembled and assembled. Combined with the detachable structure of the rear wheels, this achieves modularity in the overall stroller structure, significantly reducing the complexity of disassembly and assembly. It solves the problem of inconvenient disassembly and assembly of the front wheel components, allowing the stroller to be quickly disassembled into smaller, independent parts when not in use, facilitating packing, transportation, or storage in confined spaces. Optionally, the flexible frame includes a base sheet, side sheets, and a back sheet, with the bottom side of the back sheet connected to the rear side of the base sheet; two side sheets are provided, each side sheet being disposed on one side of the base sheet; each side sheet has an adjacent first connecting edge and a second connecting edge, the first connecting edge being used to connect with the base sheet, and the second connecting edge being used to connect with the back sheet.

[0019] Optionally, the flexible frame further includes a bevel, the bottom end of which is connected to the front end of the bottom piece, and the top end of which is connected to the top end of the back piece; the side of the bevel is used for connecting the side piece; the bevel has an opening for items to pass through.

[0020] By adopting the above technical solution, the inclined plate at the front end forms a barrier against the items in the flexible frame, preventing items from falling out of the trolley.

[0021] Optionally, the inclined plate is further provided with a dustproof net, which is movably connected to the inclined plate and is used to open and close the opening. By adopting the above technical solution, the items in the flexible frame are protected from dust, and the items in the flexible frame are also made visible.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The frame can be completely disassembled into three independent components—the base frame, the inclined frame, and the movable frame—through a detachable connection and sliding hinge structure. This, combined with a flexible frame that can be rolled up for storage, reduces the overall volume. The independently detachable pulley assembly design avoids interference with storage space caused by the wheel and axle structure. 2. The rear wheel assembly is made into an independent module by the cooperation of the detachable rod and the through hole. During disassembly, only the detachable rod needs to be removed to separate all the rear wheels. At the same time, the through hole axially limits the detachable rod to prevent the components from being misaligned during disassembly. 3. By setting up inclined plates and installing dustproof nets on the inclined plates for opening and closing the openings, safety is improved while ensuring convenience. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a toy cart that can be quickly assembled. (See also...) Figures 1 to 4 A toy cart that can be quickly assembled includes a flexible frame 1 made of flexible material, a frame body 2 made of rigid material, and a detachable pulley assembly 3.

[0030] The frame 2 includes a base frame 21, a diagonal frame 22, a movable frame 23, and a handle frame 24. The bottom end of the diagonal frame 22 is hinged to the front end of the base frame 21, and the top end of the movable frame 23 is hinged to the top end of the diagonal frame 22. A sliding member 25 that slides along the base frame 21 is provided at the bottom end of the movable frame 23. The handle frame 24 is movably connected to the top end of the diagonal frame 22, and the distance between the end of the handle frame 24 away from the diagonal frame 22 and the diagonal frame 22 is adjustable.

[0031] The base frame 21 has a connection point for fixing the inclined frame 22. When the inclined frame 22 is connected to the base frame 21 at the connection point, the frame body 2 is in an unfolded trolley-like shape. The pulley assembly 3 is detachably connected to the frame body 2.

[0032] The flexible frame 1 refers to a container structure made of bendable fabric or silicone material, which can be connected to the frame body 2 using Velcro, buckles, or straps for quick assembly, disassembly, and folding. The frame body 2 refers to a supporting skeleton made of metal tubing or engineering plastics, forming a foldable structure through hinged joints. The sliding component 25 refers to a slider structure located at the bottom of the movable frame 23, which can be a plastic slider with a limiting groove that cooperates with the guide rail on the base frame 21 to allow the movable frame 23 to slide and adjust along the length of the base frame 21. The connection point refers to the positioning hole or slot provided on the base frame 21, which can be used to fix the inclined frame 22 to a specific position on the base frame 21 using pins or elastic buckles to ensure the stability of the trolley.

[0033] In this embodiment, the base frame 21 is provided with a positioning element 211 at the connection point. The positioning element 211 is used to fix the inclined frame 22 and the base frame 21 to each other at the connection point. The specific fixing method is snap-fit ​​limiting. When the inclined frame 22 is extended to a preset angle, the buckle at the connection point of the base frame 21 automatically engages into the corresponding groove of the inclined frame 22, forming a rigid connection. At this time, the inclined frame 22, the base frame 21, and the movable frame 23 together form a triangular support structure. The positioning element 211 restricts the rotational freedom of the inclined frame 22 to prevent the connection from loosening due to vibration during the movement of the trolley.

[0034] The movable connection refers to the relative position change between the handle frame 24 and the inclined frame 22 through a rotatable or sliding mechanical structure. Specifically, it can be achieved by using a hinge or slide rail mechanism, so that the handle frame 24 can rotate around the connection point or move along a specific trajectory.

[0035] The adjustable distance refers to adjusting the spatial interval between the handle 24 and the inclined frame 22 by changing the position of the end of the handle 24 relative to the inclined frame 22. This can be achieved using a telescopic rod or a folding linkage mechanism, with a locking device to fix different adjustment positions. In this embodiment, the handle 24 is hinged to the inclined frame 22. In other embodiments, the handle 24 and the inclined frame 22 can also be detachably connected via a snap-fit ​​connection or a threaded connection.

[0036] When storage is required, release the fixing of the connection point between the inclined frame 22 and the base frame 21, push the movable frame 23 to move the sliding component 25 forward along the base frame 21, causing the inclined frame 22 to fold towards the base frame 21. The flexible frame 1 can be rolled up and compressed after being removed from the frame body 2, and the pulley assembly 3 can be stored separately after separation. In use, push the movable frame 23 backward to unfold the frame, fix the inclined frame 22 to the connection point, install the pulley assembly 3 and connect the flexible frame 1. Through the cooperation of the hinge structure and the sliding component 25, the frame body 2 can switch between the folded and unfolded states, and the overall volume can be compressed in conjunction with the detachable parts.

[0037] In this embodiment, the pulley system includes a pair of front wheels 31 and a pair of rear wheels 32, and both front wheels 31 are detachably connected to the front end of the base frame 21.

[0038] In this embodiment, the flexible frame 1 includes a base plate 11, side plates 12, a back plate 13, and an inclined plate 14. The bottom side of the back plate 13 is connected to the rear side of the base plate 11. Two side plates 12 are provided, one on each side of the base plate 11. Each side plate 12 has an adjacent first connecting edge and a second connecting edge. The first connecting edge is used to connect to the base plate 11, and the second connecting edge is used to connect to the back plate 13. The bottom end of the inclined plate 14 is connected to the front end of the base plate 11, and the top end of the inclined plate 14 is connected to the top end of the back plate 13. The side of the inclined plate 14 is used for connecting the side plates 12, and the inclined plate 14 has a through opening 15 for items to pass through.

[0039] Among them, the substrate 11 refers to the bottom support structure of the flexible frame 1, which can be made of flexible fabric or silicone material.

[0040] Among them, the side piece 12 refers to the side enclosure structure of the flexible frame 1, which can be implemented by separate independent pieces. The two side pieces 12 are symmetrically distributed on both sides of the base piece 11 and are connected to the edge of the base piece 11 through the first connecting edge.

[0041] Among them, the back piece 13 refers to the rear enclosure structure of the flexible frame 1. Specifically, it can be implemented using a sheet structure of the same material as the base piece 11. The bottom side is connected to the back side of the base piece 11 by stitching or Velcro to form a flip-up vertical support surface.

[0042] Among them, the inclined piece 14 refers to the flexible sheet structure that connects the front end of the bottom piece 11 and the top end of the back piece 13. Specifically, it can be achieved by using nylon cloth to be Velcro-attached to the bottom piece 11 and snap-on to the back piece 13. The inclined extension forms a triangular support surface to enhance the stability of the frame.

[0043] In this embodiment, the bottom piece 11, side piece 12, back piece 13 and oblique piece 14 are fixedly connected by stitching.

[0044] Furthermore, the inclined plate 14 is movably connected to a dustproof net 16 via a zipper. The dustproof net 16 is used to open and close the opening 15, thereby providing dust protection while also making the space inside the flexible frame 1 visible. In other embodiments, the dustproof net 16 and the inclined plate 14 can also be movably connected by Velcro, magnetic fasteners, or snaps.

[0045] Furthermore, the base frame 21 also includes a detachable rod 212, which extends along the width of the base frame 21. A through hole 213 is provided at the rear end of the base frame 21 for the detachable rod 212 to pass through. A pair of rear wheels 32 are detachably connected to both ends of the detachable rod 212.

[0046] The detachable connection of the rear wheel 32 refers to the detachable fixing method between the rear wheel 32 and the detachable rod 212, which can be achieved by threaded engagement, snap-fit ​​structure or plug pin, allowing the rear wheel 32 to be disassembled separately or the detachable rod 212 assembly to be removed as a whole.

[0047] A detachable rod 212 passes through a through hole 213 at the rear end of the base frame 21, forming a lateral support structure. A pair of rear wheels 32 are respectively installed at both ends of the detachable rod 212. When it is necessary to remove the rear wheels 32, the rear wheels 32 can be directly unscrewed or pulled out from both ends of the detachable rod 212, and the detachable rod 212 can also be pulled out from the through hole 213, so that the rear end of the base frame 21 loses its lateral support component. By separating the rear wheels 32 from the detachable rod 212, and separating the detachable rod 212 from the base frame 21, the rear wheel 32 system can be modularly disassembled, reducing the space occupied during storage.

[0048] The implementation principle of a quickly assembled toy cart according to an embodiment of this application is as follows: When storage is required, the connection point between the inclined frame 22 and the base frame 21 is released, and the movable frame 23 is pushed to move the sliding component 25 forward along the base frame 21, causing the inclined frame 22 to fold towards the base frame 21. The flexible frame 1 can be rolled up and compressed after being removed from the frame body 2, and the pulley assembly 3 can be stored separately after separation. In use, the movable frame 23 is pushed back to unfold the frame, the inclined frame 22 is fixed to the connection point, the pulley assembly 3 is installed, and the flexible frame 1 is connected. Through the cooperation of the hinge structure and the sliding component 25, the frame body 2 can switch between a folded state and an unfolded state, and the overall volume can be compressed in conjunction with the detachable parts.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
