[0009] Furthermore, the lock mechanism includes a lock bolt and an elastic member, and both the lock bolt and the elastic member are attached to the positioning member. The positioning member is configured to accurately arrange the lock bolt and the elastic member in the attachment chamber.

[0010] Furthermore, the lock mechanism includes a traction member and an opening / closing member. The traction member is installed in the attachment chamber. One end of the traction member is connected to the lock bolt, and the other end is connected to the opening / closing member. The opening / closing member is configured to control the telescoping of the lock bolt via the traction member.

[0011] Furthermore, the opening and closing member is installed outside the frame.

[0012] Furthermore, the slide sleeve is provided with a fixing groove, which is formed inwardly in an elliptical shape along the edge of the slide sleeve. In the initial state, the fixing groove engages with the locking pin.

[0013] Furthermore, the linkage includes a first linkage unit and a second linkage unit, which are arranged to intersect on the frame. The first linkage unit and the second linkage unit are configured to control the folding and telescoping of the main frame. In the initial state, the angle formed by the first linkage unit and the second linkage unit is a.

[0014] Furthermore, the opening and closing member includes a hinge seat and a movable block. The hinge seat is connected to the frame, and the movable block is hinge-connected to the hinge seat. The hinge seat is connected to the traction member.

[0015] Here, when the movable block rotates outward along the hinge axis, the locking bolt is pulled through the traction member, and the main frame is folded. The present invention further provides a baby stroller applying any of the above embodiments, including a cart body, a folding basket is attached to the cart body, and is detachably connected to the cart body.

Advantages of the Invention

[0016] The foldable basket and stroller according to the present invention include a main frame, a plurality of frames, a slide sleeve, and a locking mechanism. The main frame is composed of a plurality of frames, and each frame is interlocked via a linkage to achieve folding and telescoping. The slide sleeve is slidably installed on the frame and is hinge-connected to the linkage. The locking mechanism is installed in the frame corresponding to the slide sleeve and is configured to control the folding and telescoping of the main frame.

[0017] In the present invention, when the locking mechanism is engaged with the slide sleeve, the main frame maintains an extended state. As the slide sleeve slides along the frame, the main frame assumes a folded state. Through the coordinated operation of the slide sleeve, the linkage, and the locking mechanism, when the main frame is in the extended state, the locking mechanism is securely engaged with the slide sleeve to achieve stable support. On the other hand, when folding is required, by the user releasing the locking mechanism, the slide sleeve slides along the frame, and the linkage interlocks and folds, causing the plurality of frames to contract synchronously, enabling rapid folding.

[0018] This design enables folding to be completed with one touch without the need for complicated adjustments, realizing the simplification of the operation process. This improves the convenience for users and also contributes to the improvement of storage efficiency, thus expecting to enhance the market competitiveness.

[0021] The achievement of the object, functional features, and advantages of the present invention will be described in more detail based on the embodiments and the accompanying drawings. Specific embodiments of the present invention will be described, but this is not intended to limit the present invention and is for illustrative purposes only.

[0022] In the description of the present invention, it is necessary to understand the meanings of the following terms. Expressions indicating orientation or positional relationships such as "center", "longitudinal direction", "lateral direction", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "upper part", "bottom part", "inner side", "outer side", "clockwise", and "counterclockwise" are based on the positional relationships on the drawings and are for facilitating the description only. Since it does not imply that a specific device or component is configured and operates according to this orientation, it does not limit the present invention.

[0023] "First" and "second" are for identification only and do not imply the importance or quantity of elements. Therefore, the features marked with "first" and "second" can explicitly or implicitly include one or more. The term "plurality" means two or more unless otherwise specifically limited. Also, in the present invention, unless otherwise specifically defined or limited, the following terms should be interpreted broadly. Terms such as "attach", "connect", and "couple" should be interpreted broadly and include fixed connections, detachable connections, integral connections, etc. Also, it includes not only mechanical connections but also direct connections, indirect connections through a medium, internal connections, or interactions. The specific meanings of these terms should be appropriately understood by those skilled in the art according to the embodiments of the present invention.

[0024] Furthermore, the statement that "the first feature is 'above' or 'below' the second feature" includes not only the case of direct contact but also the case of contact via intermediate elements. Also, the expressions "the first feature is 'above', 'upper', 'upper surface' of the second feature" include not only the case of being exactly above but also the case of being obliquely above or simply having a higher height. Similarly, the expressions "the first feature is 'below', 'lower', 'lower surface' of the second feature" include not only the case of being exactly below but also the case of being obliquely below or having a lower height.

[0025] Referring to FIG. 1, a foldable sleeping basket according to an embodiment of the present utility model has the following configuration. Main frame (100): Composed of a plurality of frames, which are interlocked via a link mechanism to realize folding and telescoping of the main frame (100); Slide sleeve (200): Mounted slidably on the frame and hinge-connected to the link mechanism; Locking mechanism: Provided inside the corresponding slide sleeve (200) to control folding and telescoping of the main frame (100);

[0026] In this technology, when the locking mechanism engages with the slide sleeve (200), the main frame (100) maintains a telescopic state. When the slide sleeve (200) slides along the frame, the main frame (100) becomes a folded state.

[0027] This technology aims to solve the problem that the operation of the conventional folding mechanism is complicated and difficult to use. Through the coordinated operation of the main frame (100), the slide sleeve (200), and the locking mechanism, the folding and deployment of the pet cart can be performed more simply and efficiently.

[0028] Furthermore, a link mechanism is adopted for the connection between the frames, which minimizes the occupied space after folding while ensuring the stability during deployment. With this design, not only are the user's operation steps reduced, but also the safety and portability of the pet cart are improved, providing a more convenient user experience.

[0029] In this embodiment, the frame is composed of a top frame (110), a folding frame (120), and a bottom frame (130), and is connected via a link mechanism to form a space available for the user and to achieve the expansion and folding of the main frame (100). Specifically, the slide sleeve (200) is slidably attached to the folding frame (120), and the locking mechanism is installed on the folding frame (120). In addition, the folding frame (120) is provided with a through hole for the locking mechanism to enter and exit the inside and outside of the folding frame (120). When the user folds the pet cart, by releasing the locking mechanism, the locking mechanism contracts into the folding frame (120), and the slide sleeve (200) slides along the frame.

[0030] Due to this sliding motion, the link mechanism operates in conjunction, and the top frame (110), the folding frame (120), and the bottom frame (130) contract simultaneously, completing the folding quickly. In this design, multiple adjustment operations are not required, and it can be folded with one touch, simplifying the operation procedure and improving convenience and storage efficiency. The design of this embodiment has the following advantages compared with the conventional folding pet cart.

[0031] Simple operation: It does not require complicated two-handed operations and can be quickly folded and deployed with one touch. Time saving: It can be folded and deployed in a short time, reducing the stress during use. Stable structure: High stability during deployment, preventing accidental folding and improving safety. Compact storage: The folding design using a link mechanism minimizes the volume after folding, making it easy to carry and store. This design meets the market demand for portable sleeping baskets and folding pet carts, enhancing the competitiveness of the product.

[0032] In this embodiment, an attachment chamber 140 is provided on the frame, and a positioning member 800 is inserted into the attachment chamber 140. The positioning member 800 is configured for positioning the attachment position of the lock component; The lock mechanism includes a lock bolt 300 and an elastic member 310, both of which are attached to the positioning member 800. The positioning member 800 is designed to accurately position and attach the lock bolt 300 and the elastic member 310 to the attachment chamber 140.

[0033] The folding frame 120 is provided with an attachment chamber 140, and the positioning member 800 is pushed in from the opening of the attachment chamber 140. The positioning member 800 is provided with a lock holder 810, which realizes a stable connection between the positioning member 800 and the folding frame 120. Also, the design of the lock holder 810 prevents the occurrence of angular deviation when the positioning member 800 is pushed into the attachment chamber 140.

[0034] In this embodiment, both the lock bolt 300 and the elastic member 310 are arranged on the positioning member 800. By the function of the positioning member 800, the lock bolt 300 and the elastic member 310 are accurately attached to the attachment chamber 140. The distance between the through hole of the folding frame and the opening of the attachment chamber 140 is set to be equal to the length of the positioning member 800. When the positioning member 800 is pushed into the attachment chamber 140 together with the lock bolt 300 and the elastic member 310, it is designed such that the lock bolt 300 exactly coincides with the through hole.

[0035] With this design, precise installation of the locking component is achieved. The plug-in installation by the positioning member 800 simplifies the installation of the locking component and improves the installation accuracy, thereby reducing the possibility of malfunction due to angular deviation. In addition, since the lock bolt 300 and the elastic member 310 are accurately connected to the installation chamber 140 via the positioning member 800, a reliable locking function is realized, and the stability of the main frame 100 during folding and unfolding is improved. The overall design not only enhances the structural rationality of the folding mechanism but also optimizes the operability of the user, realizing smoother and more convenient folding and unfolding. Thereby, an improvement in the market competitiveness of the product can be expected.

[0036] In another embodiment, the locking component includes a lock bolt 300 and an elastic member 310, and the elastic member 310 is attached to the frame. The elastic member 310 is disposed within the installation chamber 140, with one end in contact with the inner wall of the installation chamber 140 and the other end connected to the lock bolt. The elastic member 310 is configured to assist the fit between the lock bolt 300 and the slide sleeve 200 and to realize the folding and telescoping of the main frame 100.

[0037] The slide sleeve 200 is provided with a fixing groove 500, and the fixing slot 500 opens inward in an elliptical shape along the edge of the slide sleeve 200. In the initial state, the fixing slot 500 is designed to be compatible with the lock bolt. With this design, stable operation of the locking mechanism is ensured, and the folding and telescoping of the main frame 100 are performed smoothly.

[0038] Based on the above embodiments, the locking mechanism includes a traction member (320) and an opening / closing member (400). The traction member (320) is installed within the installation chamber (140), with one end connected to the lock bolt and the other end connected to the opening / closing member (400). The opening / closing member (400) is configured to drive the traction member (320) and expand and contract the lock bolt.

[0039] In this embodiment, the opening and closing member (400) is installed outside the frame. The opening and closing member (400) is configured to include a hinge seat (410) and a movable block (420). The hinge seat (410) is connected to the frame, and the movable block (420) is rotatably provided with respect to the hinge seat (410). The hinge seat (410) is connected to the traction member (320).

[0040] When the movable block (420) is rotated outward along the hinge axis, the lock bolt (300) can be pulled in through the traction member (320), and the main frame (100) can be folded. The locking mechanism includes the opening and closing member (400) provided outside the folding frame (120) and the traction member (320) disposed in the mounting chamber (140). By arranging the opening and closing member (400) outside, it is designed to be easily operable by the user. The traction member (320) is composed of a wire rope and is driven by the opening and closing member (400) to push the lock bolt (300), compress the elastic member (310), and pull the lock bolt (300) into the mounting chamber (140). This operation realizes the folding of the main frame (100).

[0041] Specifically, the opening and closing member (400) is composed of a hinge seat (410) and a movable block (420). The movable block (420) is connected to the traction member (320) on the side facing the hinge seat (410). When the movable block (420) is rotated outward in the hinge axis direction, the traction member (320) operates to push the lock bolt (300) and compress the elastic member (310).

[0042] In this embodiment, by adopting the opening and closing member (400) and the traction member (320), the intuitiveness and convenience of the folding operation are improved. Compared with the structure that only controls the lock by the conventional elastic member (310), by providing the opening and closing member (400) outside the folding frame (120), the user can directly operate the parts without having to put their hands inside the folding mechanism, improving the convenience and intuitiveness of the operation. The traction member (320) (wire rope) is arranged in the mounting chamber (140), and by connecting the lock bolt (300) and the opening and closing member (400), the user can control its expansion and contraction without directly touching the lock bolt (300).

[0043] By performing the operation of pulling the traction member (320) by the opening and closing member (400), the contraction of the lock bolt (300) is realized, enabling the folding of the main frame (100). The lock bolt (300) protrudes from the through hole of the folding frame (120) by the force of the elastic member (310) and fits into the fixed slot (500) to ensure the stability of the main frame (100). When the user rotates the movable block (420) outward, the traction member (320) is pulled, pushing the lock bolt (300) and compressing the elastic member (310).

[0044] The lock bolt (300) is pulled into the mounting chamber (140), and the locked state is released. In this state, the main frame (100) can be smoothly folded. When the opening and closing member (400) is returned to its original position, the lock bolt (300) protrudes from the through hole again by the force of the elastic member (310) and fits into the fixed slot (500), keeping the trolley in a stable deployed state. Due to the external arrangement of the opening and closing member (400), the user can perform the folding operation intuitively. By adopting the traction member (320), the operation of the lock bolt (300) becomes smooth, preventing the lock from getting stuck due to friction. The design of the opening and closing member (400) and the hinge seat (410) applies a uniform force to the traction member (320), preventing damage and loosening caused by load concentration and improving durability.

[0045] In this embodiment, for the folding / expansion of the main frame (100), the first linkage unit (600) and the second linkage unit (700) are arranged crosswise. The first linkage unit (600) and the second linkage unit (700) function as structures that assist in the folding / expansion of the main frame (100). In the initial state (folded state), the angle between the first linkage unit (600) and the second linkage unit (700) is a. When the locking mechanism is connected to the slide sleeve (200), the angle between the first linkage unit (600) and the second linkage unit (700) changes to b, and the relationship b > a holds.

[0046] This design can improve the stability of the cart during deployment. The contraction / expansion of the folding frame (120) becomes smoother, and the compactness after folding is improved. When the locking mechanism is activated, the slide sleeve (200) moves on the frame, changing the form of the linkage, so that the angle between the first linkage unit (600) and the second linkage unit (700) expands to b, and an overall stable deployment state is obtained. This design realizes mechanical smooth folding / expansion, enabling intuitive use of the cart without complicated operations. By minimizing friction and snagging during folding, durability is improved.

[0047] The present invention further provides a stroller to which any of the above embodiments is applied, including a cart body, a folding basket is attached to the cart body and is detachably connected to the cart body. In this embodiment, running wheels are provided at the lower end of the cart body, and a gripping portion is arranged at the upper end of the cart body. The folding basket is detachably attached to the cart body, and the user can operate the stroller while adapting to the running road surface using the gripping portion.

[0048] When the user uses the stroller mode, the foldable basket is stably attached to the cart body, forming an integrated load support structure. The running wheels provide mobility, and the gripping part assists in direction operation. On the other hand, when the user removes the foldable basket and uses it alone, it can be easily separated by the detaching mechanism, so it can also be used as an independent pet bed and can be folded and stored. This embodiment combines the highly convenient folding design of the foldable basket to reduce the volume after folding, making storage and carrying easier.

[0049] Overall, this embodiment combines the foldable basket and the cart body to further improve the practicality of the product, resulting in a design that combines mobility, a flexible folding function, and structural stability. This enables it to meet various usage scenarios and enhance market competitiveness.

[0050] The foldable basket and stroller of the present invention are suitable for use in public places such as urban areas, parks, pedestrian streets, and shopping malls. It is useful when pet owners want to go out with their pets but want to avoid having their pets walk constantly or come into direct contact with the ground. In particular, small pets (such as cats, small dogs, and elderly dogs) have limited physical strength and are easily fatigued by long walks, so the pet cart provides a comfortable resting space.

[0051] It is also suitable when taking pets that need regular reexamination or rehabilitation treatment at the animal hospital, as it can reduce the burden of long-distance walking. This design is easy to fold and unfold and is suitable for daily use. This can suppress the physical exhaustion of pets, provide a more comfortable outdoor experience, and ensure the safe movement of pets with difficulty in moving.

[0052] Note that the above description of the present invention is merely the best embodiment and does not limit the scope of the patent of the present invention. Even when equivalent structural and functional conversions using the content of the description and drawings of the present invention, or when applied directly or indirectly to other related technical fields, they shall be included in the scope of patent protection of the present invention.
