Description

Technical field

[0001] The utility model relates to the technical field of carrying baskets, in particular a foldable carrying basket structure and a trolley. State of the art

[0002] Carrying baskets, with their ample space and load capacity, are used in a variety of applications, including in the home, logistics, retail, outdoor work, pet and mother-child care, goods transfer, warehousing, outdoor travel, pet care, and mother-child care. Their primary function is the centralized storage and transport of various people, animals, and items (including infants, pets, everyday necessities, logistics packages, tools, and equipment, etc.).

[0003] Currently, most commercially available carrying basket structures are monolithic in construction. This means that the core structure – frame, receiving cavity, and outer shell (if present) – is either integrally formed or permanently joined. This monolithic design of the carrying basket structure can meet basic load-bearing capacity requirements in practical applications.

[0004] Due to the increasing demand for mobility and low weight, various support devices used with carrying baskets (such as trolley frames, logistics transfer frames, and temporary storage frames) are generally designed to be foldable. This allows them to be folded when not in use, reducing their size and facilitating storage and transport. However, existing integrated carrying baskets are inherently rigid and cannot be folded. When used with foldable support devices, whether in combination with a foldable trolley frame in mother-child situations or a foldable transfer frame in logistics, the carrying basket structure retains its original size even after the support device is folded. This results in the overall size of the "support device-carrying basket" combination remaining large after folding, making integrated and compact storage impossible.This requires more storage space, for example for home storage, which limits the application and impairs the user experience.

[0005] Therefore, the solution to the aforementioned deficiencies of the prior art is the subject of this utility model and is to be investigated and resolved. Summary of the utility model

[0006] The subject of the utility model is the provision of a foldable carrying basket structure and a trolley.

[0007] To achieve the above-mentioned purpose, the following technical solution is used in the utility model: A foldable carrying basket structure comprises a left frame structure, a support structure and a right frame structure arranged sequentially along a first direction; The support structure comprises two support elements spaced apart in the second direction and a base; the support element includes: a support section extending along a third direction and located on the base; a sliding section which is arranged to be displaceable along the third direction on the support section; The left frame structure includes: a first upper surrounding section which is rotatably connected to one side of the sliding section; a first lower support section which is rotatably connected to one side of the support section; a first middle surrounding section which is rotatably connected to the first upper surrounding section and the first lower support section and is rotatably connected to the base; The right-hand framework structure includes: a second upper surrounding section that is rotatably connected to the other side of the sliding section; a second lower support section which is connected to the other side of the support section in a relatively rotatable manner; a second middle surrounding section, which is rotatably connected to the second upper surrounding section and the second lower support section and is rotatably connected to the base; The foldable carrying basket structure is arranged such that during the transformation from the unfolded state to the folded state, the sliding section slides on the support section along the third direction (and approaches the assembly arrangement), and that during the transformation, the first upper environmental section, the first middle environmental section, and the first lower support section are driven by the sliding section to approach the corresponding second upper environmental section, the second middle environmental section, and the second lower support section and fold together to form a minimal volume.

[0008] The first middle surrounding section is rotatably connected to the first upper surrounding section via a first connecting section. The first lower support section is rotatably connected to the first middle surrounding section via a second connecting section. The second middle surrounding section is rotatably connected to the second upper surrounding section via a third connecting section. The second lower support section is rotatably connected to the second middle surrounding section via a fourth connecting section.

[0009] The first upper surrounding section is rotatably connected to one side of the sliding section. It is understood that the first upper surrounding section is rotatably connected to both sliding sections.

[0010] This application also describes a cart with the foldable carrying basket structure described above.

[0011] This application describes the use of a carrying basket structure for carrying a baby, but does not limit the use of the carrying basket structure for carrying pets, objects, etc.

[0012] This application describes the first direction as parallel to the width direction of the support section, the second direction as parallel to the thickness direction of the support section, and the third direction as parallel to the length direction (extent direction) of the support section. The first, second, and third directions are orthogonal to each other.

[0013] The sliding section is arranged on the support section such that it slides along the third direction. It is understood that the sliding section can be moved up and down relative to the support section. Using the sliding section as an example, similar arrangements (such as the left and right frame structures) are described here: the support structure comprises two sliding sections. The two sliding sections may differ, for example, in shape, but preferably they have the same structure.

[0014] Using the lower end of the support section as an example, the upward and downward directions are based on the upward and downward directions encountered during normal user use, and the specific area is not limited. A distinction is made only between the upper end, the top end, and the lower end. The position of the relevant structure can be specified.

[0015] The support section can be a hollow structure with a cavity inside.

[0016] The description of the right frame structure is referenced here, using the left frame structure as an example: The first upper support section can be a U-shaped or near-U-shaped support bar. Together with the two support sections and the second upper support section, this support bar forms a protective zone that prevents infants and pets from easily falling out of the carrier. Even if a fabric cover is attached to the outside of the carrier, the support bar can securely hold it in place. An elastic buffer structure (e.g., a torsion spring or a corresponding protrusion or slot) can be attached to the junction between the first upper support section and the sliding section to provide cushioning during the deployment phase of the first upper support section, thus improving the carrying experience.

[0017] The first middle support section can be a U-shaped or approximately U-shaped middle support bar. In a first direction, one end of the middle support bar (with two lower ends) is rotatably connected to the lower ends of the two support sections, while the other end is rotatably connected to the first upper support section via a first connecting section. The middle support bar also serves to protect and drive the first lower support section.

[0018] The first lower support section can be a plate-shaped structure that can be used to carry the baby and represents the supporting structure in the carrier basket structure.

[0019] There is no restriction regarding the specific structure of the first connecting section; however, for better understanding, an example is given here: the first connecting section can be placed on the outside of the end of the first upper environmental section that faces away from the sliding section, and can thus rotate relative to the first upper environmental section. Simultaneously, the first connecting section can be engaged with the end of the first middle environmental section that faces away from the support section, and can thus move synchronously with the first middle environmental section, thereby realizing a mutually rotatable arrangement of the first upper environmental section and the first middle environmental section.

[0020] There is no restriction regarding the specific structure of the second connection section, but for better understanding, an example is given here: the second connection section can comprise a plate-like structure and a rod-like structure; the plate-like structure is rigidly connected to the first lower support section (this serves as an example; the specific connection method is not restricted and exists); one end of the rod-like structure is rotatably connected to the plate-like structure, and the other end is rotatably connected to the first middle surrounding section; as an example, with reference to Fig. 1 the plate-like structure comprises two sub-plates and the two sub-plates are each arranged at both ends of the first lower support section in the second direction; to give further examples, the connection position of the sub-plates and the first lower support section is not restricted.

[0021] The carrying basket structure has an unfolded state and a folded state: During the transition from the unfolded to the folded state, the sliding section moves from the upper end of the support section downwards to the lower end of the support section, causing the first upper support section and the second upper support section to rotate closer together. Using the first upper support section as an example, it drives the first middle support section via the first connecting section, and the first middle support section drives the first lower support section via the second connecting section, ensuring that the carrying basket structure can be stowed easily and quickly.

[0022] During the transition from the folded state to the unfolded state, the sliding section moves from the lower end region of the support section upwards to the upper end region of the support section, the first upper surrounding section and the second upper surrounding section rotate away from each other, the first middle surrounding section and the second middle surrounding section rotate away from each other, and the first lower support section and the second lower support section rotate away from each other.

[0023] In summary, the present application offers a carrier structure with a foldable design that can be switched between unfolded and folded states, thus meeting the needs of users in different phases of life. In particular, the folding mechanism reduces the carrier structure's footprint, facilitating storage and transport. Furthermore, the carrier structure features a simple and reliable design that provides stable support for infants or pets and meets the user's need for long-term, reliable use. In addition, the carrier structure is relatively easy to operate, making it simple for the user to change its configuration and enhancing the user experience.

[0024] According to another technical solution, the left frame structure and the right frame structure are arranged symmetrically in the first direction; and / or The two support sections and the two sliding sections are each arranged symmetrically in the second direction.

[0025] It is understandable that the symmetrical arrangement is based on a specific state of the carrying basket structure, such as the unfolded usage state (the unfolded state mentioned above) and the folded storage state (the folded state mentioned above).

[0026] It is understandable that the two examples of the left and right frame structures are symmetrical structures that, while sharing the same basic structure, differ in their specific arrangement, such as the structure's position. Based on this, it is practical to create the carrying basket structure while simultaneously maintaining its aesthetic appeal.

[0027] By adjusting this part, it can be ensured that the carrying basket structure can stably switch between the unfolded usage state and the folded storage state over a long period of time, and that the required space can be controlled.

[0028] According to another technical solution, the support section is provided with two sliding grooves corresponding to the sliding sections and arranged symmetrically in the first direction, and the sliding grooves extend along the third direction; and / or The sliding sections are arranged in the form of a closed ring and the sliding sections are arranged around the outer circumference of the support section.

[0029] Although, for example, it is not clear along which support section the sliding sections are arranged, the person skilled in the art should know from the complete description and the drawings that they are arranged along the perimeter of the adjacent support section.

[0030] In the first direction, two symmetrical surfaces of the support section are recessed to form a sliding groove, which may have a T-shaped cross-section. Parts of the sliding section are inserted into the two sliding grooves, thus achieving a stable sliding connection between the sliding section and the support section. Compared to providing only one sliding groove, providing two sliding grooves ensures a more stable sliding connection between the sliding section and the support section.

[0031] The sliding groove can run through the upper end of the support section, and the upper end of the support section can be detachably provided with a limiting structure to prevent the sliding section from unexpectedly detaching from the sliding groove due to an upward movement.

[0032] The sliding section is attached to the outside of the support section. The sliding section does not have to be ring-shaped; it can, for example, be approximately U-shaped. However, the closed ring shape of the sliding section increases its structural strength and ensures a stable sliding connection between the sliding section and the support section. The exact shape of the sliding section is Fig. 9 can be seen.

[0033] According to another technical solution, in the second direction the area between the two support sections is defined as the interior area; The sliding section has a first surface and a second surface in the second direction; at least part of the first surface is located on a side of the adjacent support section facing away from the interior; the second surface comprises two second sub-surfaces, and the two second sub-surfaces are arranged on two symmetrical sides of the adjacent support sections along the first direction; the two ends of the first upper surrounding section in the second direction are each rotatably connected to the corresponding two second partial surfaces; The two ends of the second upper surrounding section in the second direction are each rotatably connected to the corresponding two second partial surfaces.

[0034] The interior area is actually the inner usable area of ​​the carrying basket structure when unfolded.

[0035] The entire portion of the first surface can be located on the side of the adjacent support section facing away from the interior. If the first surface is an arc-shaped surface, its central portion can be located on the side of the adjacent support section facing away from the interior, while the projections of the two end portions can be located on the adjacent support section in a direction parallel to the first surface.

[0036] For example, if the entire first surface is located on the side of the adjacent support section facing away from the interior, the sliding section does not occupy the interior space. This ensures the usable area of ​​the interior and avoids safety risks (or damage to objects) caused by a collision between a baby and the sliding section.

[0037] The sliding section has two support blocks arranged symmetrically to the adjacent support sections along the first direction. The two second undersides are each positioned on the two support blocks. Using the first upper surrounding section as an example, the two ends of the first upper surrounding section are each rotatably connected to the corresponding two support blocks in the second direction. The type of rotary connection is present and will not be described in detail here. This arrangement utilizes the lateral space of the support section in the first direction, allowing the size of the carrier structure to be controlled in the second direction.Using the example of the first upper surrounding section, the first upper surrounding section is rotatably connected to the first surface, increasing the size of the carrying basket structure in the second direction, thereby changing the usable area inside the carrying basket structure and the space requirement of the entire carrying basket structure, and also significantly reducing the aesthetics of the carrying basket structure.

[0038] According to another technical solution, a projection of the second sub-surface is located in a fourth direction on the adjacent support section, and the fourth direction is parallel to the first direction; and / or In the direction of the support section towards the interior, the surface of the support section towards the interior, the surface of the corresponding end of the first upper surrounding section towards the interior, and the surface of the corresponding end of the second upper surrounding section towards the interior are arranged flush or nearly flush.

[0039] Preferably, the projection of the second partial surface in the fourth direction is located in the central region of the adjacent support section in the second direction. This preferred embodiment is described using the example of the first upper surrounding section. This section provides space for the corresponding end of the first upper surrounding section on the side of the support section along the first direction and prevents the corresponding end of the first upper surrounding section from projecting towards the interior of the support section, thus preventing the corresponding end of the first upper surrounding section from occupying only the inner usable area of ​​the carrier structure. This arrangement can satisfy various design requirements, such as ensuring a sufficiently large inner usable area.

[0040] Using the support section and the first upper surrounding section as an example, the interior-facing surface of the support section is flush or nearly flush with the interior-facing surface of the corresponding end of the first upper surrounding section. This not only ensures the utilization of the lateral space of the support section along the first direction, but also guarantees that the corresponding end of the first upper surrounding section occupies little or no usable interior surface area of ​​the support basket structure. In the nearly flush arrangement, the distance between the two surfaces in the interior-facing direction of the support section is not specifically limited, for example, to one centimeter.The description of the near-flush arrangement serves only to assist with different design requirements, with a flush arrangement being preferred. If the sliding section is arranged annularly around the outer circumference of the support section, the interior-facing surface of the sliding section can be flush or nearly flush with the interior-facing surface of the corresponding end of the first upper surrounding section in the direction of the support section.

[0041] According to another technical solution, in the second direction the first upper surrounding section has two first connecting ends for rotatable connection with the sliding section, the first middle surrounding section has two second connecting ends for rotatable connection with the base, and the first lower support section has two third connecting ends for rotatable connection with the base; In the second direction, the two second connection ends and the two third connection ends lie between the two first connection ends; In the second direction, the second upper surrounding section has two fourth connecting ends for rotatable connection with the sliding section, the second middle surrounding section has two fifth connecting ends for rotatable connection with the base, and the second lower support section has two sixth connecting ends for rotatable connection with the base; In the second direction, the two fifth connection ends and the two sixth connection ends each lie between the two fourth connection ends.

[0042] The first upper surrounding section is shown as an example. The first upper surrounding section can be U-shaped or approximately U-shaped, and the first upper surrounding section has two ends (i.e., first connecting ends) in the second direction.

[0043] In the second direction, the two second connecting ends and the two third connecting ends all lie between the two first connecting ends. This means that when the carrier structure is folded and stowed, the first upper surrounding section encloses the first middle surrounding section and the first lower support section (not forming a closed loop). This improves the foldability of the carrier structure and ensures that it occupies relatively little space when folded (the exact area is not limited). Reference is made here to the following description of the fourth connecting end and other arrangements.

[0044] The first lower support section comprises a support plate that can be used to support an infant (existing configuration). Preferably, the two second connecting ends are aligned with the two third connecting ends in the third direction to ensure the size of the support plate in the second direction. Reference is made to the description of the second lower support section.

[0045] In the present application, the support structure also includes a connecting element extending along the second direction. Both ends of the connecting element in the second direction are each rigidly connected to the lower ends of the two support sections.

[0046] The connecting element is preferably a plate-like structure that supports the carrying of the infant while simultaneously increasing the structural strength and stability of the carrier structure, etc. The connecting element can also be a single or multiple rod-like structures, for example, two rod-like structures arranged side by side in the first direction. The connecting element can also be a combination of rod-like and plate-like structures, with the plate-like structure mounted on top of the rod-like structure, the rod-like structure connected to the base, and the plate-like structure also connected to the base.

[0047] Preferably, when the carrying basket structure is unfolded, the top surfaces of the connecting element, the first lower support section and the second lower support section are flush with each other.

[0048] Another technical solution provides that it further comprises a locking element and an unlocking element; the locking element serves to limit the downward movement of the sliding section relative to the support section; the unlocking element serves to release the positional locking of the locking element on the sliding section; and One of the locking and unlocking elements is movably provided at the upper end of at least one support section, and the other of the locking and unlocking elements is movably provided on at least one sliding section.

[0049] Preferably, one of the locking and unlocking elements is movably provided on each support section, and the other of the locking and unlocking elements is movably provided on each sliding section.

[0050] When the sliding section reaches the top of the support section, the carrying basket structure unfolds for use. The locking element limits the downward movement of the sliding section relative to the support section, thus preventing the carrying basket structure from collapsing and being stowed. This ensures the structural stability of the carrying basket structure during use and prevents safety hazards caused by unexpected collapsing and stowing. When the carrying basket structure needs to be folded and stowed, the release element actuates the locking element to release the limiting lock on the sliding section, ensuring smooth collapsing and stowing of the carrying basket structure. It is emphasized that the area of ​​the top of the support section is not restricted.

[0051] Another technical solution provides that a surface of at least one of the support sections, which faces away from the other support section, is concave in order to form a groove, a limiting section is movably provided in the groove, the limiting section forms the locking element and the limiting section can limit the downward movement of the sliding section by protruding from the groove; at least one of the sliding sections is provided with a bore extending along the second direction, a pressure section is movably provided in the bore corresponding to the limiting section, the pressure section forms the unlocking element, and the pressure section can release the limiting section from the limit of the sliding section by pressing on the limiting section.

[0052] The groove on the surface of the support section can also be shaped like a hole.

[0053] The limiting mechanism of the limiting section can be configured as follows: The sliding section can move downwards along the length of the support section (parallel to the third direction), while the limiting section can move along the thickness of the support section (parallel to the second direction) to protrude from the groove (only a portion of the limiting section needs to protrude). The portion of the limiting section protruding from the groove is configured as a stop structure. This stop structure cannot move along the length of the support section, thus preventing the downward movement of the sliding section. This ensures the structural stability of the carrying basket structure during use and prevents safety hazards caused by unexpected folding and stowing.The specific mechanism by which the stop structure fulfills the limiting function is not restricted here and can be achieved by contact with the underside of the sliding section.

[0054] It should be noted that if one of the support sections is provided with the aforementioned groove, the adjacent sliding section must be provided with the aforementioned bore to fulfill the aforementioned purpose. This is not described in further detail here.

[0055] The interaction between the limiting and pressure sections can be designed as follows: The limiting section is inserted into the bore to restrict the movement of the sliding section along the longitudinal direction of the support section. An operator can push the pressure section, causing it to move along the thickness direction of the support section and pushing the limiting section out of the bore. This eliminates the effect of the limiting section's positional limitation on the sliding section, ensuring smooth folding and stowing of the carrying basket structure.

[0056] The pressure section can be configured to push the boundary section completely into the groove, without specific limitations and adjustable as needed.

[0057] The push button section can be a button protruding from the sliding section. In this case, a button cover with a perforated structure for the button passage is attached to the outside of the sliding section.

[0058] In this configuration, the pressure section is exposed on the outside of the carrying basket structure, thus facilitating operation.

[0059] Another technical solution provides that the groove comprises a first lower groove and a second lower groove, which are connected to each other; the limiting section comprises a limiting subsection and an engagement subsection, which are connected to each other; the limiting subsection and the engagement subsection correspond to the first lower groove and the second lower groove, respectively; the limiting subsection can limit the downward movement of the sliding section by extending out of the first lower groove; In the first direction, the size of the second lower groove and the size of the engagement subsection are both larger than the size of the first lower groove in order to limit the complete separation of the boundary section and the groove.

[0060] The boundary subsection and the engagement subsection can be formed in one piece.

[0061] When the boundary section is completely within the groove, the boundary subsection is located within the first and second sub-grooves, and the engagement subsection is located within the second sub-groove.

[0062] The actual limiting structure is the limiting subsection within the limiting section. This limiting subsection extends beyond the first lower slot to restrict the downward movement of the sliding section, thus preventing the carrying basket structure from collapsing and stowing. This ensures the structural stability of the carrying basket structure during use and prevents safety risks caused by unexpected collapsing and stowing.

[0063] In the first direction, the size of the second lower groove and the size of the engagement subsection are both larger than the size of the first lower groove. Consequently, the engagement subsection cannot penetrate the first lower groove, thus preventing the limiting section from completely disengaging from the groove. This prevents the sliding section from becoming unlimited and locked due to the limiting section falling out. This ensures the long-term stability of the support cage structure.

[0064] It should be noted that the structure and size setting of the pressure section and the bore may refer to the structure and size setting of the boundary section and the groove, and the purpose is also to prevent the pressure section from detaching from the entire carrier basket structure.

[0065] Another technical solution involves sloping the bottom wall of the groove downwards in the longitudinal direction of the support section, so that a section of the limiting section can automatically move out of the groove; or that the limiting section is connected to the wall of the groove via a return element (e.g. a spring or an elastic element) and the return element can cause a section of the limiting section to automatically move out of the groove.

[0066] This design allows the limiting section to automatically extend from the groove and thereby automatically lock the sliding section, reducing the number of steps required by the user. The pressure section can be designed similarly, further reducing the number of steps required.

[0067] Since the limiting section automatically extends from the groove, it can immediately lock the sliding section during its upward movement. This method eliminates the need for the user to observe the position of the sliding section before actuating the limiting section, making operation simple and convenient.

[0068] The return element can be a spring structure, such as a compression spring. Alternatively, it can be an existing elastic pad (e.g., made of rubber). The return element simply needs to fulfill the purpose described above. Likewise, the angle of inclination of the groove's bottom wall is not limited, as long as it fulfills the purpose described above.

[0069] Another technical solution involves inclined the bottom wall or side wall of the boundary section in the longitudinal direction of the support section, so that the sliding section can push the boundary section along the thickness direction of the support section; and / or in the longitudinal direction of the support section, the top of the boundary section is a plane.

[0070] The following describes how to adjust the slope of the bottom wall of the boundary section.

[0071] The angle parameters and other parameters of the inclination of the bottom wall of the boundary section are not limited.

[0072] The sliding section can preferably press the boundary section completely into the groove.

[0073] The use of inclined surfaces for transmission between two structures moving in different directions is a common technique (refers only to the transmission process), and the principle is not explained in detail here.

[0074] Preferably, an inclined surface corresponding to the bottom wall of the boundary section can be provided on the sliding section to improve the transmission efficiency between the sliding section and the boundary section.

[0075] As the carrier structure unfolds, the sliding section moves upwards and gradually contacts the bottom wall of the limiting section. The sliding section then continues its upward movement, driving the limiting section towards the bottom wall of the groove. Consequently, the limiting section cannot impede the upward movement of the sliding section. This eliminates the need for additional movement of the limiting section to prevent obstruction of the sliding section's upward movement. As a result, the number of steps required during the unfolding phase of the carrier structure is reduced.

[0076] Another technical solution provides that the bore has two openings in the second direction, with the opening furthest from the adjacent support section serving as the first opening and the opening closest to the adjacent support section serving as the second opening; in the first direction the size of the first opening is larger than the size of the second opening; and In the third direction, the size of the first opening is larger than the size of the second opening.

[0077] This means that the length and width of the first opening are each larger than the length and width of the second opening. The pressure section has a large head end and a small head end, with the small head end located between the large head end and the adjacent support section. The large head end is used by the operator to push. It is larger (compared to the small head end), which makes pushing easier for the operator and simplifies operation when folding the carrier structure. The small head end is used to push the limiting section. It is smaller (compared to the large head end), which reduces design costs. This allows the range of movement of the small head end to be limited in the second direction to prevent it from entering the adjacent groove and obstructing the downward movement of the sliding section.Because the small head end is smaller, at least part of the boundary section (the part that engages with the small head end) is also smaller, which can further reduce design costs. Additionally, the groove can be opened smaller, reducing the difficulty of modifying the support section.

[0078] Another technical solution provides that it further comprises at least one mounting arrangement, wherein the mounting arrangement is provided on one side of at least one base; The assembly arrangement includes: a mounting seat that is rotatably connected to one side of the base and serves to mount the carrying basket structure to the frame structure; and a locking section which is movably provided on the mounting seat and serves to limit the rotation of the mounting seat by locking it to the mounting seat.

[0079] Another technical solution provides that it further comprises at least one mounting arrangement, wherein the mounting arrangement is provided on one side of at least one base; The assembly arrangement includes: a mounting seat rotatably connected to the lower end of an adjacent support section and used for mounting the carrier basket structure to the frame structure; at least part of the mounting seat is located on a side of the adjacent support section facing away from the other support section; and a locking section which is movably provided on the adjacent support section and serves to limit the rotation of the mounting seat by locking it to the mounting seat.

[0080] The following example illustrates the assembly of the entire carrier structure with a stroller frame using the included mounting hardware. This does not affect the possibility of mounting the carrier structure on other frames.

[0081] The mounting seat is the structure that connects to the stroller frame. Existing methods can be used for assembly. For example, the mounting seat is pluggable. In this position, it protrudes downwards from the support section. The protruding part can be inserted into the stroller or pet stroller frame and connected to it, thus attaching the carrier structure to the stroller or pet stroller frame.

[0082] The mounting seat is rotatably connected to one side of the base. The mounting seat and base can be arranged together on the outside of the same support shaft. This rotatable connection method follows an existing method and does not constitute a novelty of this application.

[0083] At least part of the mounting seat is located on the side of the adjacent support section facing away from the other support section. Part of the mounting seat may be located below the adjacent support section, but the entire mounting seat is located on the side of the adjacent support section facing away from the other support section, which facilitates gripping for the operator.

[0084] The locking section can be locked to the mounting seat to limit its rotation and thus ensure the stability of the assembly consisting of the carrier structure and the stroller frame.

[0085] When the locking section unlocks the mounting seat, the mounting seat can rotate so that its protruding section points in the first direction (this is only an example; it need not be the first direction). This prevents the protruding section from increasing the space required by the carrier structure in the third direction. In some embodiments, the locking section can relock the mounting seat after the rotation, so that the protruding section of the mounting seat can be stably oriented in the first direction.

[0086] The mounting seat can be rotated in any direction, clockwise, counterclockwise or in both directions.

[0087] Preferably, the two mounting arrangements are arranged symmetrically in the second direction, with one mounting arrangement being located on the underside of each support section to ensure the stability of the carrier basket structure.

[0088] Preferably, the locking section is movably arranged on the adjacent support section along the thickness direction of the support section.

[0089] Preferably, the locking section is equipped with a return structure, which may resemble the return element described above. Alternatively, the support section may be provided with a guide chamfer to guide the return of the locking section (see the bottom wall of the groove described above).

[0090] Another technical solution involves enclosing the mounting seat and its base to form a recess, with the locking mechanism positioned within this recess. This arrangement protects the locking mechanism and increases its lifespan. In this case, the locking mechanism is an integrated structure that requires no additional space, further reducing the storage space required for the carrier structure. This also improves the aesthetics of the carrier structure, and the risk of injury to small children or other individuals can be reduced by minimizing the number of protruding and exposed components.

[0091] Another technical solution provides for a recess on the mounting seat corresponding to the locking section, and a section of the locking section (hereinafter referred to as the engagement section) can be inserted into the recess to limit the rotation of the mounting seat.

[0092] There can be multiple recesses and engagement sections, for example, three recesses distributed in a row. This not only improves the stability of the locking arrangement between the locking section and the mounting seat, but also allows the mounting seat to be relocked after it has been rotated.

[0093] Another technical solution provides that the assembly arrangement further includes a release section which is slidably arranged on the base, wherein the release section is a component for driving the locking section in order to separate it from the mounting seat.

[0094] The following description assumes that the unlocking section is slidably arranged along the third direction on the adjacent support section. This is the preferred embodiment.

[0095] To better understand this, an example is given: The locking section touches the mounting seat to lock it. To unlock it, the release section moves downwards and drives the locking section to move it along the second direction, thus unlocking the mounting seat.

[0096] This arrangement of the release section ensures that the operator can quickly and reliably unlock the mounting seat from the locking section. This arrangement of the release section is particularly necessary when the locking section is an integrated structure.

[0097] Another technical solution provides that the unlocking section is provided with a first inclined surface and the locking section is provided with a second inclined surface corresponding to the first inclined surface, and that during the downward movement, the unlocking section can drive the locking section by pressing the first inclined surface against the second inclined surface to separate it from the mounting seat.

[0098] The following example illustrates this for better understanding. The locking section contacts the mounting seat to lock it. To unlock, the release section moves downwards, causing the first inclined surface to gradually come into contact with the second inclined surface. The release section then continues to move downwards, causing the first inclined surface to press against the second inclined surface, thus moving the locking section in the second direction and unlocking the mounting seat.

[0099] In some embodiments, the release section comprises two release levers positioned on either side of the support section in the first direction. Each release lever may be equipped with two release surfaces which together form the first inclined surface.

[0100] Another technical solution involves the projection of the sliding section along the longitudinal axis of the support section partially overlapping with the projection of the adjacent release section. In this arrangement, the sliding section moves downwards during the transition from the extended to the folded state, gradually contacting the release section and pressing it downwards to automatically unlock the mounting seat. This further reduces the number of operating steps for the user, shortens the folding time required to fold the carrier structure, and improves the user experience.

[0101] This also includes a trolley comprising the foldable carrying basket structure according to one of the above embodiments.

[0102] The terms "first", "second", etc., used in this document do not specifically refer to a sequence or order, nor are they used to restrict this case. They serve only to distinguish components or processes that are described using the same technical terms.

[0103] In the sense used here, “connected” or “positioned” can refer to two or more components or devices that are in direct or indirect physical contact with each other, or to two or more components or devices that work together or move together.

[0104] The terms “comprise”, “include”, “have”, etc. used in this document are open terms and mean that they “include, but are not limited to”.

[0105] Here, terms generally use their usual meaning in the field, in the context of this disclosure, and in the specific context. Certain terms used to describe this disclosure are explained below or elsewhere in this specification to provide the person skilled in the art with additional guidance regarding this disclosure.

[0106] The terms "front", "back", "top", "bottom", "left", "right", etc., used in this article are all directional terms. In this case, they serve only to illustrate the positional relationship between the different structures and not to limit the scope of protection in this case or the specific direction in actual implementation.

[0107] The operating principle and advantages of this utility model are as follows: The carrying basket structure has an unfolded and a folded state: During the transition from the unfolded to the folded state, the sliding section moves from the upper end of the support section downwards to the lower end of the support section, causing the first upper support section and the second upper support section to rotate closer together. Using the first upper support section as an example, the first upper support section drives the first middle support section, and the first middle support section drives the first lower support section, ensuring that the carrying basket structure can be stowed easily and quickly.

[0108] During the transition from the folded state to the unfolded state, the sliding section moves from the lower end region of the support section upwards to the upper end region of the support section, the first upper surrounding section and the second upper surrounding section rotate away from each other, the first middle surrounding section and the second middle surrounding section rotate away from each other, and the first lower support section and the second lower support section rotate away from each other.

[0109] In summary, the present application offers a carrier structure with a foldable design that can be switched between unfolded and folded states, thus meeting the needs of users in different phases of life. In particular, the folding function reduces the carrier structure's footprint, facilitating storage and transport and expanding its range of applications. Furthermore, the carrier structure is characterized by a simple and reliable design that provides stable support for infants and pets and meets the user's need for long-term, stable use. In addition, the carrier structure is relatively easy to operate, which simplifies changing the carrier's state and increases user comfort.

[0111] The present application is described in more detail below with reference to the attached drawings and embodiments: Embodiment: The present application is explained in more detail below with reference to drawings and detailed descriptions. After understanding the embodiments of the present application, any person skilled in the art can make changes and modifications based on the techniques conveyed by the present application without departing from the scope of the present application.

[0112] The terms used here serve solely to describe specific embodiments and do not constitute a limitation of the present application. Singular forms such as "ein", "der", "dieser", "diese" and "das" also include plural forms.

[0113] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16 to Fig. As shown in Figure 17, a foldable carrying basket structure comprises a left frame structure 1, a support structure 2 and a right frame structure 3, arranged sequentially along a first direction; The support structure 2 comprises two support elements 21 spaced apart in the second direction and a base 23; the support element 21 comprises: a support section 211 extending along a third direction and arranged on the base 23; a sliding section 212, which is provided to be displaceable along the third direction on the support section 211; The left frame structure 1 includes: a first upper surrounding section 11, which is rotatably connected to one side of the sliding section 212; a first lower support section 14, which is rotatably connected to one side of the support section 211; a first middle surrounding section 12, which is rotatably connected to the first upper surrounding section 11 and the first lower support section 14 and is rotatably connected to the base 23; the right frame structure 3 comprises: a second upper surrounding section 31, which is rotatably connected to the other side of the sliding section 212; a second lower support section 34, which is rotatably connected to the other side of the support section 211; a second middle surrounding section 32, which is rotatably connected to the second upper surrounding section 31 and the second lower support section 34 and is rotatably connected to the base 23; The foldable carrying basket structure is arranged such that during the transformation from the unfolded state to the folded state, the sliding section 212 slides on the support section 211 along the third direction and approaches the mounting arrangement 9, and that during the transformation, the first upper environmental section 11, the first middle environmental section 12, and the first lower support section 14 are driven by the sliding section 212 to approach the corresponding second upper environmental section 31, the second middle environmental section 32, and the second lower support section 34 and fold together to form a minimal volume.

[0114] This embodiment is described as using the carrying basket structure for carrying a baby, but the carrying basket structure is not limited to use for carrying objects.

[0115] This embodiment is described under the assumption that the first direction is parallel to the width direction of the support section 211, the second direction is parallel to the thickness direction of the support section 211, and the third direction is parallel to the length direction (expansion direction) of the support section 211.

[0116] The first direction is parallel to the X direction in the figure, the second direction is parallel to the Y direction in the figure, and the third direction is parallel to the Z direction in the figure.

[0117] The sliding section 212 is arranged to be displaceable along the third direction on the support section 211. It is understood that the sliding section 212 can be moved up and down relative to the support section 211. Using the sliding section 212 as an example, similar arrangements (such as the left frame structure 1 and the right frame structure 3) are described here: The support structure 2 comprises two sliding sections 212. The two sliding sections 212 may differ, for example, in shape, but preferably they have the same structure.

[0118] Using the lower end of support section 211 as an example, the upward and downward directions are based on the structural direction in Fig. 1, and the specific area is not limited. A distinction is made only between the upper end, the top end, and the lower end. The position of the relevant structure is in Fig. 5 to see.

[0119] The support section 211 can be a hollow structure with a cavity inside.

[0120] The two support sections 211 can be connected to the same basket support structure to allow a user to lift the support basket structure.

[0121] Using the left frame structure 1 as an example, the description of the right frame structure 3 is referenced here: The first upper surrounding section 11 can be a U-shaped or approximately U-shaped upper surrounding bar (see Fig. 1) The upper support bar, together with the two support sections 211 and the second upper support section 31, can form a protective zone that prevents the baby from falling out of the carrier structure. Even if a fabric cover is attached to the outside of the carrier structure, the upper support bar can securely support it. An elastic buffer structure (e.g., a torsion spring) can be provided at the connection between the first upper support section 11 and the sliding section 212, so that the first upper support bar 11 has a cushioning effect during the unfolding phase, thus improving the carrying experience.

[0122] The first mean environmental section 12 can be a U-shaped or approximately U-shaped mean environmental bar (see Fig. 1) In a first direction, one end of the central surrounding rod (with two lower ends) is rotatably connected to the lower ends of the two bases 231, the other end is rotatably connected via a first connecting section 13 to the first upper surrounding section 11. The central surrounding rod also serves as protection and for driving the first lower support section 14.

[0123] The first lower support section 14 can be a plate-shaped structure (see Fig. 1), which can be used to support carrying the baby and represents the actual carrying structure in the carrier basket structure.

[0124] There is no restriction regarding the specific structure of the first connecting section 13 (see Fig. 1), but for better understanding, an example is provided here: the first connecting section 13 can be slid onto the outside of the end of the first upper environmental section 11 that is away from the sliding section 212, and can thereby rotate relative to the first upper environmental section 11. At the same time, the first connecting section 13 can be engaged with the end of the first middle environmental section 12 that is away from the support section 211, and can thereby move synchronously with the first middle environmental section 12, thus realizing a mutually rotatable arrangement of the first upper environmental section 11 and the first middle environmental section 12.

[0125] There is no restriction regarding the specific structure of the second connecting section 15 (see Fig. 1), but for better understanding, an example is given here: the second connecting section 15 can comprise a plate-like structure and a rod-like structure; the plate-like structure is rigidly connected to the first lower support section 14 (this serves as an example; the specific connection method is not limited and exists); one end of the rod-like structure is rotatably connected to the plate-like structure, and the other end is rotatably connected to the first middle surrounding section 12; as an example, with reference to Fig. 1 the plate-like structure comprises two sub-plates and the two sub-plates are each arranged at both ends of the first lower support section 14 in the second direction; to give a further example, the connection position of the sub-plates and the first lower support section 14 is not restricted (see Fig. 1).

[0126] The carrying basket structure has an unfolded state (see Fig. 1) and a folded state (see Fig. 5): During the transition from the unfolded state to the folded state (see Fig. 4) The sliding section 212 moves from the upper end of the support section 211 downwards to the lower end of the support section 211, causing the first upper surrounding section 11 and the second upper surrounding section 31 to rotate closer to each other. Using the first upper surrounding section 11 as an example, it drives the first middle surrounding section 12 via the first connecting section 13, and the first lower surrounding section 12 drives the first lower support section 14 via the second connecting section 15, thus enabling the carrying basket structure to be stowed easily and quickly.

[0127] During the transition from the folded state to the unfolded state (see Fig. 4) the sliding section 212 moves from the lower end region of the support section 211 upwards to the upper end region of the support section 211, the first upper surrounding section 11 and the second upper surrounding section 31 rotate away from each other, the first middle surrounding section 12 and the second middle surrounding section 32 rotate away from each other and the first lower support section 14 and the second lower support section 34 rotate away from each other.

[0128] In summary, this embodiment offers a carrier structure that is foldable and can be switched between unfolded and folded states to meet the needs of users at different stages of life. In particular, folding the carrier reduces its footprint, thereby expanding its range of applications. Furthermore, the carrier structure is characterized by its simple and reliable design, providing stable support for infants and meeting the user's need for long-term, reliable use. In addition, the carrier structure is relatively easy to operate, which facilitates changing the carrier's state and increases user comfort.

[0129] As in the Fig. As shown in Figures 1-3, in this embodiment the left frame structure 1 and the right frame structure 3 are arranged symmetrically in the first direction; and / or The two support sections 211 and the two sliding sections 212 are each arranged symmetrically in the second direction.

[0130] It is understandable that the symmetrical arrangement is based on a specific state of the carrying basket structure, such as the unfolded usage state (the unfolded state mentioned above) and the folded storage state (the folded state mentioned above).

[0131] It is understandable that the left frame structure 1 and the right frame structure 3, for example, are symmetrical structures that, while sharing the same basic structure, have different specific arrangements, such as the position of the structure. Based on this, the carrying basket structure can be conveniently manufactured without compromising its aesthetics.

[0132] By adjusting this part, it can be ensured that the carrying basket structure can stably switch between the unfolded usage state and the folded storage state over a long period of time, and that the required space can be controlled.

[0133] As in the Fig. 6, Fig. As shown in Figure 8, in this embodiment the support section 211 is provided with two sliding grooves 2111 which are arranged symmetrically in the first direction, corresponding to the sliding sections 212, and the sliding grooves 2111 extend along the third direction; and / or The sliding sections 212 are arranged in the form of a closed ring and the sliding sections 212 are arranged around the outer circumference of the support section 211.

[0134] Although, for example, it is not clear along which support section 211 the sliding sections 212 are arranged, the person skilled in the art should know from the complete description and the drawings that they are arranged along the perimeter of the adjacent support section 211.

[0135] In the first direction, two symmetrical surfaces of the support section 211 are concave with sliding grooves 2111, which may have a T-shaped cross-section. Parts of the sliding section 212 are inserted into the two sliding grooves 2111, thereby achieving a stable sliding connection between the sliding section 212 and the support section 211. Compared to providing only one sliding groove 2111, providing two sliding grooves 2111 ensures a more stable sliding connection between the sliding section 212 and the support section 211.

[0136] The sliding groove 2111 can extend through the upper end of the support section 211, and the upper end of the support section 211 can be removably provided with a limiting structure to prevent the sliding section 212 from unexpectedly detaching from the sliding groove 2111 due to an upward movement.

[0137] The sliding section 212 is mounted outside the support section 211. The sliding section 212 does not have to be ring-shaped, but can be approximately U-shaped. However, the closed ring shape of the sliding section 212 increases its structural strength and ensures a stable sliding connection between the sliding section 212 and the support section 211. The specific shape of the sliding section 212 is described in Fig. 9 can be seen.

[0138] As in the Fig. 4, Fig. As shown in Figure 8, in this embodiment the area between the two support sections 211 is defined as the interior area 4 in the second direction; The sliding section 212 has a first surface 2121 and a second surface 2122 in the second direction; at least part of the first surface 2121 is located on a side of the adjacent support section 211 that points away from the interior area 4; the second surface 2122 comprises two second subsurfaces 2122a, and the two second subsurfaces 2122a are arranged on two symmetrical sides of the adjacent support section 211 along the first direction; the two ends of the first upper surrounding section 11 in the second direction are each rotatably connected to the corresponding two second partial surfaces 2122a; the two ends of the second upper surrounding section 31 in the second direction are each rotatably connected to the corresponding two second sub-surfaces 2122a.

[0139] The interior area 4 is actually the inner usage area of ​​the carrying basket structure in the unfolded state.

[0140] The entire area of ​​the first surface 2121 can lie on the side of the adjacent support section 211 facing away from the interior area 4. If the first surface 2121 is an arc-shaped surface, its central area can lie on the side of the adjacent support section 211 facing away from the interior area 4, and the projections of the two end areas in a direction parallel to the first direction can lie on the adjacent support section 211 (see Fig. 3).

[0141] Since, for example, the entire area of ​​the first surface 2121 is located on the side of the adjacent support section 211 facing away from the interior area 4, the sliding section 212 does not occupy the space of the interior area 4 (see Fig. 3) This ensures the usable area of ​​the interior space 4 and avoids safety risks (or damage to objects) caused by a collision between a baby and the sliding section 212.

[0142] The sliding section 212 has two support blocks, each arranged symmetrically on either side of the adjacent support sections 211 along the first direction. The two second partial surfaces 2122a are arranged on these two support blocks. Using the first upper surrounding section 11 as an example, the two ends of the first upper surrounding section 11 are rotatably connected to the corresponding two support blocks in the second direction. The type of rotary connection is present and will not be described in detail here. This arrangement utilizes the lateral space of the support sections 211 in the first direction, allowing the size of the support structure to be controlled in the second direction. Using the first upper surrounding section 11 as an example, the size of the support structure increases in the second direction when it is rotatably connected to the first surface 2121.This affects the usable area inside the carrying basket structure and the space required for the entire carrying basket, while simultaneously reducing the aesthetics of the carrying basket structure.

[0143] As in the Fig. 3 and Fig. As shown in Figure 8, in this embodiment the projection of the second partial surface 2122a in the fourth direction is located on the adjacent support section 211 and the fourth direction is parallel to the first direction; and / or In the direction of the support section 211 towards the interior area 4, the surface of the support section 211 towards the interior area 4, the surface of the corresponding end of the first upper surrounding section 11 towards the interior area 4 and the surface of the corresponding end of the second upper surrounding section 31 towards the interior area 4 are arranged flush or nearly flush.

[0144] Preferably, the projection of the second partial surface 2122a in the fourth direction lies in the central region of the adjacent support section 211 in the second direction (see Fig. 3) This preferred embodiment is described using the example of the first upper surrounding section 11. This section provides space for the corresponding end of the first upper surrounding section 11 on the side of the support section 211 along the first direction and prevents the corresponding end of the first upper surrounding section 11 from projecting from the support section 211 only in the direction of the support section towards the inner area 4, and thus prevents the corresponding end of the first upper surrounding section 11 from occupying only the inner usable area of ​​the carrier structure. This arrangement can satisfy various design requirements, for example, ensuring the usable area of ​​the inner usable area.

[0145] Using the example of support section 211 and the first upper surrounding section 11, the surface of support section 211 facing the interior area 4 is flush or nearly flush with the surface of the corresponding end of the first upper surrounding section 11 facing the interior area 4. This ensures that the lateral space of support section 211 is fully utilized along the first direction and simultaneously ensures that the corresponding end of the first upper surrounding section 11 does not occupy, or only minimally occupies, the usable interior space of the support basket structure. With this nearly flush arrangement, the distance between the two surfaces in the direction of support section 211 towards the interior area 4 is not specifically limited; it can, for example, be one centimeter.This description of an approximately flush arrangement is merely an aid to accommodate different design requirements; a flush arrangement is preferred. If the sliding section 212 is arranged in a closed ring shape and surrounds the outer circumference of the support section 211, the surface of the sliding section 212 facing the inner region 4 can be flush or approximately flush with the surface of the corresponding end of the first upper surrounding section 11 facing the inner region 4 in the direction of the support section 211 towards the inner region 4.

[0146] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. As shown in Figure 5, in this embodiment the first upper surrounding section 11 has two first connecting ends 111 for rotatable connection with the sliding section 212 in the second direction, the first middle surrounding section 12 has two second connecting ends 121 for rotatable connection with the base 23 and the first lower support section 14 has two third connecting ends 141 for rotatable connection with the base 23.

[0147] In the second direction, the two second connection ends 121 and the two third connection ends 141 are all located between the two first connection ends 111.

[0148] In the second direction, the second upper surrounding section 31 has two fourth connecting ends 311 for rotatable connection with the sliding section 212, the second middle surrounding section 32 has two fifth connecting ends 321 for rotatable connection with the base 23, and the second lower support section 34 has two sixth connecting ends 341 for rotatable connection with the base 23.

[0149] In the second direction, the two fifth connection ends 321 and the two sixth connection ends 341 are all located between the two fourth connection ends 311.

[0150] The first upper environmental section 11 is shown as an example and it is referred to Fig. 1 referred to. The first upper surrounding section 11 can be U-shaped or approximately U-shaped and the first upper surrounding section 11 has two ends (i.e. first connecting ends 111) in the second direction.

[0151] In the second direction, the two second connection ends 121 and the two third connection ends 141 all lie between the two first connection ends 111. Thus, the first upper surrounding section 11 encloses the first middle surrounding section 12 and the first lower support section 14 (not a closed loop, see Fig. 5) when the carrying basket structure is folded and stowed away. This improves the foldability of the carrying basket structure and ensures that the carrying basket structure takes up relatively little space when folded (the specific dimensions are not limited). The following description of the fourth connection end 311 and other configurations is referenced here.

[0152] The first lower support section 14 comprises a support plate that can be used to support an infant (as described here). Preferably, the two second connecting ends 121 are aligned in the third direction with the two third connecting ends 141 (see Fig. 5) to ensure the dimensions of the support plate in the second direction. The description of the second lower support section 34 is referenced here.

[0153] As in Fig. As shown in Figure 1, the support structure 2 in this embodiment further comprises a connecting element 22 extending along the second direction, and both ends of the connecting element 22 in the second direction are each firmly connected to the lower ends of the two support sections 211.

[0154] Preferably, the connecting element 22 is a plate-like structure (see Fig. 1) which supports the carrying of an infant or pet and improves the structural strength and stability of the carrier structure. The connecting element 22 can also be a single or multiple rod-like structures, for example, two rod-like structures arranged side by side in the first direction. The connecting element 22 can also be a combination of a rod-like and a plate-like structure, wherein the plate-like structure is mounted on the top of the rod-like structure, the rod-like structure is connected to the support section 211, and the plate-like structure is also connected to the support section 211.

[0155] Preferably, in the unfolded state of the carrying basket structure, the top surfaces of the connecting element 22, the first lower support section 14 and the second lower support section 34 are flush with each other.

[0156] According to the Fig. 6 - Fig. In this embodiment, 9 further comprises a locking element 5 and a release element 6; the locking element 5 serves to limit the downward movement of the sliding section 212 relative to the support section 211; the release element 6 serves to release the positional locking of the locking element 5 on the sliding section 212.

[0157] One of the locking elements 5 and unlocking elements 6 is movably provided at the upper end of at least one support section 211 and the other of the locking elements 5 and unlocking elements 6 is movably provided on at least one sliding section 212.

[0158] The downward movement of the sliding section 212 is determined based on the design direction in Fig. 1 described and will not be described in detail here.

[0159] Preferably, one of the locking elements 5 and unlocking elements 6 is movably provided on each support section 211 and the other of the locking elements 5 and unlocking elements 6 is movably provided on each sliding section 212.

[0160] When the sliding section 212 reaches the top of the support section 211, the carrying basket structure unfolds for use. The locking element 5 limits the downward movement of the sliding section 212 relative to the support section 211, thus preventing the carrying basket structure from folding and stowing. This ensures the structural stability of the carrying basket structure during use and prevents safety risks due to unexpected folding and stowing. When the carrying basket structure needs to be folded and stowed, the release element 6 actuates the locking element 5 to release the limiting lock on the sliding section 212, thus ensuring smooth folding and stowing of the carrying basket structure. It is emphasized that the area of ​​the top of the support section 211 is not restricted. The position of the sliding section 212 when the carrying basket structure is unfolded is Fig. 1 can be seen.

[0161] According to the Fig. 6 - Fig. In this embodiment, 9 is a surface of at least one of the support sections 211, which is concave facing away from the other support section 211 in order to form a groove 2112, a limiting section 7 is movably provided in the groove 2112, the limiting section 7 forms the locking element 5 and the limiting section 7 can limit the downward movement of the sliding section 212 by protruding from the groove 2112; at least one of the sliding sections 212 is provided with a bore 2123 extending along the second direction, a pressure section 8 is movably provided in the bore 2123 in accordance with the limiting section 7, the pressure section 8 forms the unlocking element 6 and the pressure section 8 can release the limiting section 7 from the limit of the sliding section 212 by pressing on the limiting section 7.

[0162] The groove 2112 on the surface of the support section 211 can also be shaped like a hole.

[0163] The limiting mechanism of the limiting section 7 can be configured as follows: The sliding section 212 can move downwards along the length of the support section 211 (parallel to the third direction), while the limiting section 7 can move along the thickness of the support section 211 (parallel to the second direction) to protrude from the groove 2112 (only a portion of the limiting section 7 needs to protrude). The portion of the limiting section 7 protruding from the groove 2112 is configured as a stop structure. This stop structure cannot move along the length of the support section 211 and thus prevents the downward movement of the sliding section 212. This ensures the structural stability of the carrying basket structure during use and prevents safety risks from unexpected folding and stowing.The specific mechanism by which the stop structure fulfills the limiting function is not restricted here and can be achieved by contact with the underside of the sliding section 212 (This is only an example and not the arrangement in the attached figure. See ). Fig. 15).

[0164] It should be noted that if one of the support sections 211 is provided with the aforementioned groove 2112, the adjacent sliding section 212 is provided with the aforementioned bore 2123 to fulfill the aforementioned purpose. This is not described in more detail here.

[0165] The interaction of limiting section 7 and pressure section 8 can be configured as follows: Limiting section 7 is inserted into bore 2123 to restrict the movement of sliding section 212 along the longitudinal direction of support section 211. An operator can push pressure section 8, causing it to move along the thickness direction of support section 211 and forcing limiting section 7 out of bore 2123. This eliminates the effect of limiting section 7's positional restriction on sliding section 212, ensuring smooth folding and stowing of the carrying basket structure.

[0166] The pressure section 8 can be configured to fully push the limiting section 7 into the groove 2112 without specific restrictions and is adjustable as required.

[0167] The pressure section 8 can be a button protruding from the sliding section 212. In this case, a button cover with a perforated structure for the button passage is attached to the outside of the sliding section 212.

[0168] In this configuration, pressure section 8 is exposed on the outside of the carrying basket structure, which facilitates the operation of pressure section 8. (Referring to...) Fig. In this embodiment, the groove 2112 comprises a first lower groove and a second lower groove, which are connected to each other; the limiting section 7 comprises a limiting subsection 71 and an engagement subsection 72, which are connected to each other; the limiting subsection 71 and the engagement subsection 72 correspond to the first lower groove and the second lower groove, respectively; the limiting subsection 71 can limit the downward movement of the sliding section 212 by extending out of the first lower groove; In the first direction, the size of the second lower groove and the size of the engagement subsection 72 are both larger than the size of the first lower groove in order to limit the complete separation of the limiting section 7 and the groove 2112.

[0169] The limiting subsection 71 and the intervention subsection 72 can be formed in one piece.

[0170] When the limiting section 7 is completely located in the groove 2112, the limiting subsection 71 is located within the first and second sub-groove and the engagement subsection 72 is located within the second sub-groove.

[0171] Within the limiting section 7, the actual limiting structure is the limiting subsection 71. This limiting subsection 71 extends beyond the first lower slot to limit the downward movement of the sliding section 212 and thus prevent the carrying basket structure from collapsing and stowing. This ensures the structural stability of the carrying basket structure during use and prevents safety risks caused by unexpected collapsing and stowing.

[0172] In the first direction, the size of the second lower groove and the size of the engagement subsection 72 are both larger than the size of the first lower groove. Consequently, the engagement subsection 72 cannot penetrate the first lower groove, thus preventing the limiting section 7 from completely disengaging from the groove 2112. This prevents the sliding section 212 from becoming unlimited and locked due to the limiting section 7 falling down. This ensures the long-term stability of the support cage structure.

[0173] It should be noted that the structure and size setting of pressure section 8 and bore 2123 may refer to the structure and size setting of limiting section 7 and groove 2112, and the purpose is also to prevent pressure section 8 from detaching from the entire carrier structure. The structure and size of pressure section 8 and bore 2123 may relate to the Fig. 8 and Fig. 9 can be taken from.

[0174] In this embodiment, the bottom wall of the groove 2112 is inclined downwards along the length of the support section 211, so that a section of the limiting section 7 can automatically move out of the groove 2112; or The limiting section 7 is connected to the wall of the groove 2112 via a return element (not shown) and the return element can cause a section of the limiting section 7 to automatically move out of the groove 2112.

[0175] This design allows the section of the limiting section 7 to automatically extend from the groove 2112 and thereby automatically lock the sliding section 212, reducing the number of steps required by the user. The pressure section 8 can be designed similarly, further reducing the number of steps required.

[0176] Since the section of the limiting section 7 automatically extends from the groove 2112, it can immediately lock the sliding section 212 during its upward movement. This method eliminates the need for the user to observe the position of the sliding section 212 before actuating the limiting section 7, making operation simple and convenient.

[0177] The return element can be a spring structure, for example, a compression spring. Alternatively, it can be an existing elastic pad (e.g., made of rubber). The return element simply needs to fulfill the purpose described above. Likewise, the angle of inclination of the bottom wall of groove 2112 is not limited, as long as it fulfills the purpose described above.

[0178] Fig. Figure 7 shows that in this embodiment, the bottom wall or side wall of the boundary section 7 is inclined in the longitudinal direction of the support section 211, so that the sliding section 212 can push the boundary section 7 along the thickness direction of the support section 211; and / or in the longitudinal direction of the support section 211 the upper surface of the boundary section 7 is a plane The following describes how to adjust the slope of the bottom wall of boundary section 7.

[0179] The angle parameters and other parameters of the inclination of the bottom wall of the boundary section 7 are not limited, see Fig. 7.

[0180] The sliding section 212 can preferably press the limiting section 7 completely into the groove 2112.

[0181] The use of inclined surfaces for transmission between two structures moving in different directions is a common technique (refers only to the transmission process), and the principle is not explained in detail here.

[0182] Preferably, an inclined surface corresponding to the bottom wall of the boundary section 7 can be provided on the sliding section 212 in order to improve the transmission efficiency between sliding section 212 and boundary section 7.

[0183] During the unfolding of the carrier structure, the sliding section 212 moves upwards and gradually contacts the bottom wall of the limiting section 7. The sliding section 212 then continues its upward movement, driving the limiting section 7 towards the bottom wall of the groove 2112. Consequently, the limiting section 7 cannot impede the upward movement of the sliding section 212. This eliminates the need for an additional movement of the limiting section 7 to prevent obstruction of the upward movement of the sliding section 212. As a result, the number of steps required during the unfolding phase of the carrier structure is reduced.

[0184] Fig. Figure 9 shows that in this embodiment the bore 2123 has two openings in the second direction, the opening furthest from the adjacent support section 211 being the first opening 2123a and the opening closest to the adjacent support section 211 being the second opening 2123b; in the first direction the size of the first opening 2123a is larger than the size of the second opening 2123b; and in the third direction the size of the first opening 2123a is larger than the size of the second opening 2123b.

[0185] The shape of bore 2123 is in Fig. 9 can be seen.

[0186] This means that the length and width of the first opening 2123a are each larger than the length and width of the second opening 2123b. The pressure section 8 has a large head end and a small head end, with the small head end located between the large head end and the adjacent support section 211. The large head end is used by the operator for pushing. It is larger (compared to the small head end), which makes pushing easier for the operator and simplifies operation when folding the carrier structure. The small head end is used to push the limiting section 7. It is smaller (compared to the large head end), which reduces design costs. This allows the range of movement of the small head end to be limited in the second direction to prevent it from entering the adjacent groove 2112 and obstructing the downward movement of the sliding section 212.Since the small head end is smaller, at least part of the boundary section 7 (the part that engages with the small head end) is also smaller, which can further reduce design costs. Additionally, the groove 2112 can be opened smaller, reducing the difficulty of modifying the support section 211.

[0187] Fig. 10 to Fig. Figure 14 shows that in this embodiment it further comprises at least one mounting arrangement 9, wherein the mounting arrangement 9 is provided on a bottom side of at least one base 23; The assembly arrangement 9 comprises: a mounting seat 91, which is rotatably connected to one side of the base 23 and serves to mount the carrying basket structure to the frame structure; and a locking section 92, which is movably provided on the adjacent support section 211 and serves to limit the rotation of the mounting seat 91 by locking it to the mounting seat 91.

[0188] The following example illustrates the assembly of the entire carrier structure with a stroller frame using the included mounting arrangement 9. The possibility of mounting the carrier structure on other frames remains unaffected.

[0189] The lower end area of ​​support section 211 is not restricted and reference can be made to the corresponding structural positions in the attached drawings.

[0190] The assembly seat 91 is the structure that is connected to the stroller frame. Existing assembly methods can be used. An example serves to illustrate this: The assembly seat 91 is pluggable. In this state, the assembly seat 91 protrudes downwards relative to the base 23 (see Fig. 5) The protruding part can be inserted into and connected to the stroller frame, thus connecting the carrier structure to the stroller frame.

[0191] The mounting seat 91 is rotatably connected to one side of the base 23. The mounting seat 91 and the base 23 can be arranged together on the outside of the same support shaft. This rotatable connection method follows an existing method and does not constitute a novelty of this application.

[0192] At least part of the mounting seat 91 is located on the side of the base 23. Part of the mounting seat 91 may be located below the adjacent support section 211, but the entire mounting seat 91 is located on the side of the adjacent support section 211 facing away from the other support section 211, which makes it easier for the operator to grip.

[0193] The locking section 92 can be locked to the mounting seat 91 to limit its rotation and thus ensure the stability of the assembly consisting of the carrier structure and the stroller frame.

[0194] When the locking section 92 unlocks the mounting seat 91, the mounting seat 91 can rotate so that its protruding section points in the first direction (this is only an example; it need not be the first direction). This prevents the protruding section from increasing the space required by the carrier structure in the third direction. In some embodiments, the locking section 92 can re-lock the mounting seat 91 after the mounting seat 91 has rotated, so that the protruding section of the mounting seat 91 can be stably aligned in the first direction.

[0195] The assembly seat 91 can be rotated in any direction, clockwise, counterclockwise or in both directions.

[0196] Preferably, the two mounting arrangements 9 are arranged symmetrically in the second direction, with one mounting arrangement 9 of them being located on the underside of each support section 211 to ensure the stability of the carrier basket structure.

[0197] Preferably, the locking section 92 is movably arranged on the adjacent support section 211 along the thickness direction of the support section 211.

[0198] Preferably, the locking section 92 is equipped with a return structure, which may resemble the return element described above. Alternatively, the support section 211 may be provided with a guide chamfer to guide the return of the locking section 92 (see bottom wall of the groove 2112 described above).

[0199] In this embodiment, the mounting seat 91 and the corresponding base 23 are enclosed to form a receiving space (not shown), and the locking section 92 is positioned within this receiving space. This arrangement protects the locking section 92 and increases its service life. In this case, the locking section 92 is an integrated structure that requires no additional space, further reducing the storage space required for the carrying basket structure. This also improves the aesthetics of the carrying basket structure, and the risk of injury to small children or other persons can be reduced by decreasing the number of protruding and exposed structures on the carrying basket structure.

[0200] Fig. Figure 13 shows that in this embodiment a recess 911 is provided on the mounting seat 91, which corresponds to the locking section 92, and a section of the locking section 92 (hereinafter referred to as engagement section 921) can be inserted into the recess 911 to limit the rotation of the mounting seat 91.

[0201] There may be several recesses 911 and engagement sections 921. Fig. Figure 13 shows, for example, three recesses 911 distributed in a row. This not only improves the stability of the locking arrangement between the locking section 92 and the mounting seat 91, but also allows the mounting seat 91 to be relocked after it has been rotated.

[0202] Fig. 11 and Fig. Figure 12 shows that in this embodiment the assembly arrangement 9 further comprises a release section 93 which is slidably arranged on the base 23, wherein the release section 93 is a component for driving the locking section 92 in order to separate it from the mounting seat 91.

[0203] The following description assumes that the unlocking section 93 is arranged to be displaceable along the third direction on the base 23. This is the preferred embodiment.

[0204] For better understanding, an example is given: The locking section 92 contacts the mounting seat 91 to lock it. To unlock, the unlocking section 93 moves downwards and drives the locking section 92 to move it along the second direction, thereby unlocking the mounting seat 91.

[0205] This arrangement of the release section 93 ensures that the operator can quickly and reliably release the mounting seat 91 from the locking section 92. This arrangement of the release section 93 is particularly necessary when the locking section 92 is an integrated structure.

[0206] Fig. 12 and Fig. Figure 14 shows that in this embodiment the unlocking section 93 is provided with a first inclined surface 931 and the locking section 92 is provided with a second inclined surface 922 corresponding to the first inclined surface 931, and the unlocking section 93 can drive the locking section 92 during the downward movement by pressing the first inclined surface 931 against the second inclined surface 922 in order to separate it from the mounting seat 91.

[0207] The following example illustrates this for better understanding. The locking section 92 contacts the mounting seat 91 to lock it. To unlock, the unlocking section 93 moves downwards, causing the first inclined surface 931 to gradually come into contact with the second inclined surface 922. Subsequently, the unlocking section 93 moves further downwards, causing the first inclined surface 931 to press against the second inclined surface 922, which moves the locking section 92 in the second direction and unlocks the mounting seat 91.

[0208] In some embodiments, the release section 93 comprises two release levers positioned on either side of the support section 211 in the first direction. Each release lever can be equipped with two release surfaces which together form the first inclined surface 931.

[0209] Fig.Figure 17 shows that in this embodiment, the projection of the sliding section 212 in the longitudinal direction of the support section 211 partially overlaps with the projection of the adjacent release section 93. In this arrangement, the sliding section 212 slides downwards during the transition from the unfolded to the folded state, gradually contacts the release section 93, and presses it downwards to automatically release the mounting seat 91. This further reduces the number of operating steps for the user, shortens the folding time required to fold the carrying basket structure, and improves the user experience.

[0210] The above embodiments serve only to illustrate the technical concepts and features of the present application. They are intended to enable those skilled in the art to understand the present application and its implementation. They do not restrict the scope of protection of the present application. Equivalent changes or modifications made within the scope of the present application are included in the scope of protection of the present application.
