Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a bassinet and a stroller. Background Technology

[0002] With the increasing demand for maternal and infant travel, baby bassinets, as an essential tool for daily infant care and travel, have made balancing functionality and portability crucial in product design. Traditional baby bassinets are mostly fixed structures, bulky, and difficult to store, failing to meet the needs of modern families for convenient travel. Therefore, foldable baby bassinets are gradually becoming the mainstream in the market. Their core lies in achieving folding of key components such as the surround and base through reasonable structural design to reduce storage volume. However, existing foldable bassinets still have many technical shortcomings that urgently need improvement.

[0003] First, the existing foldable bassinets lack sufficient linkage between the side panels and the base. In traditional designs, the side panels, which form the frame structure of the bassinet's side enclosure, and the base, which supports the infant, are often independent folding structures: the side panels are usually hinged to fold towards each other or unfold in opposite directions, but the base is often fixed or simply connected by a single axis, resulting in a lack of synchronization between the movement trajectories of the side panels and the base during folding. For example, when the side panels fold towards each other, the base may tilt, misalign, or fail to fold completely due to the lack of linkage constraints. This not only affects storage efficiency but may also cause the bassinet to become structurally loose in the folded state, taking up extra space.

[0004] Secondly, there is a contradiction between the convenience and reliability of folding operation. To achieve quick folding of the enclosure, some products adopt a free hinge structure without locking. However, such structures are prone to accidental folding due to accidental bumps or vibrations when not in use, posing a safety hazard. While some products have added locking mechanisms such as buckles or pins, the locking operation requires additional steps such as manually pressing or rotating the locking block, and unlocking requires the use of tools or applying force at a specific angle, making the operation cumbersome. This is especially difficult to do efficiently in emergency situations such as when an infant suddenly cries and needs to be quickly put away or put away.

[0005] Furthermore, the compatibility of foldable bassinets with stroller frames, car seats, and other similar products is a significant issue. To meet the installation requirements of different vehicle models, the bassinet needs to be connected to the frame's accessories, such as mounting slots, hooks, and clips, via adapter connectors. In existing technologies, these adapter connectors are mostly single-structure components, such as fixed hooks or slots, which can only be used with specific types of frame accessories, resulting in poor versatility. Moreover, the connection lacks stability, making the bassinet prone to detaching from the frame during driving or movement due to bumps, threatening the safety of infants and toddlers.

[0006] Furthermore, the structural design of the load-bearing components limits the compactness after folding. Traditional load-bearing components are mostly directly connected to the front and rear base plates or connected by simple linkages. When folding, the connection structure between the front and rear base plates and the surrounding tubes must be operated separately, making the folding process cumbersome. Moreover, the intermediate component connecting the front and rear base plates of the transition plate lacks rotational constraints, which can easily deform or jam due to uneven force during folding, affecting the service life of the bassinet.

[0007] Therefore, this utility model was developed to address the aforementioned problems. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sleeping basket in which the enclosure tube assembly works in conjunction with the supporting assembly through a linkage component. That is, during the folding process of the front and rear enclosure tubes facing each other, the linkage component will simultaneously pull the front bottom plate to fold relative to the front enclosure tube and the rear bottom plate to fold relative to the rear enclosure tube, so that the folding action of the enclosure tube assembly and the supporting assembly is completely synchronized. This can effectively ensure that the movement trajectory of each component is consistent during the folding process of the sleeping basket, avoid misalignment or suspension of the supporting assembly and the enclosure tube assembly, and ultimately achieve "layered" storage - the enclosure tubes and the bottom plate fit tightly together, greatly reducing the storage volume, significantly improving space utilization, making it convenient for users to carry and store, and also having the characteristics of safety and reliability.

[0009] This utility model is a children's stroller that integrates an innovative bassinet structure, forming a systematic advantage in terms of storage portability, structural safety, scene adaptability, ease of operation and durability. It effectively solves the problems of traditional strollers such as "taking up space when stored, cumbersome operation, poor adaptability and many safety hazards". It is a new type of children's stroller that takes into account functionality, practicality and user experience.

During the folding process of the front enclosure tube 11 and the rear enclosure tube 12 approaching each other, the front bottom plate 21 and the rear bottom plate 23 fold towards the front enclosure tube 11 and the rear enclosure tube 12 respectively.

[0014] The adapter connection component 4 is provided on the enclosure tube assembly 1, or on the rear bottom plate 23, or on the transition connection plate 22, for detachable connection with the frame 100.

[0015] The coaxial tube joint 5 is located between the front coaxial tube 11 and the rear coaxial tube 12 and is used to lock the front coaxial tube 11 relative to the rear coaxial tube 12.

[0016] The enclosure unlocking mechanism 55 is provided on the front enclosure 11 or the rear enclosure 12 and is linked with the enclosure joint 5 so as to release the locking state of the front enclosure 11 relative to the rear enclosure 12 by linking the enclosure joint 5.

[0017] As described above, in a sleeping basket, the perimeter tube joint 5 includes a front joint block 51 and a rear joint block 52 pivotally connected to each other. The front joint block 51 is connected to the front perimeter tube 11, and the rear joint block 52 is connected to the rear perimeter tube 12. A corresponding drive portion 53 extending towards the rear joint block 52 or the front joint block 51 is formed on the front joint block 51 or the rear joint block 52. The linkage assembly 3 is rotatably connected to the end of the drive portion 53.

[0018] As described above, in a type of bassinet, a driving portion 53 extending towards a rear joint block 52 is formed on the front joint block 51; the linkage assembly 3 includes a front upper link 31, a front lower link 32, a middle link 33, a rear link 34, a first linkage rod 35, and a second linkage rod 36; the upper end of the front upper link 31 is rotatably connected to the front casing tube 11, the lower end of the front upper link 31 is rotatably connected to the upper end of the front lower link 32, and the lower end of the front lower link 32 is rotatably connected to the front bottom plate 21; the upper end of the middle link 33 is rotatably connected to the rear casing tube 12.

[0019] As described above, the enclosure joint 5 further includes a joint locking component 54 disposed between the front joint block 51 and the rear joint block 52 for positioning the front joint block 51 relative to the rear joint block 52. The enclosure unlocking mechanism 55 is used to trigger the unlocking action of the joint locking component 54 to release the locking state of the front joint block 51 relative to the rear joint block 52.

[0020] As described above, in a sleeping basket, the joint locking assembly 54 includes a joint locking part 541 disposed on the rear joint block 52 and a joint locking member 542 movably disposed on the front joint block 51 for locking and engaging with the joint locking part 541. A joint locking elastic member 543 is provided between the joint locking member 542 and the front joint block 51 for driving the joint locking member 542 to elastically reset. The enclosure unlocking mechanism 55 is used to link the unlocking action of the joint locking member 542 to release the locking state of the front joint block 51 relative to the rear joint block 52.

[0021] As described above, in a type of sleeping basket, the enclosure unlocking mechanism 55 includes an enclosure unlocking handle 551 movably disposed on the front enclosure 11, and the enclosure unlocking handle 551 is connected to the joint locking member 542 via an enclosure unlocking pull rope 552.

[0022] As described above, the adapter connection assembly 4 includes an adapter connector 41 disposed on the enclosure assembly 1 or the transition connection plate 22, an adapter locking mechanism 42 disposed on the adapter connector 41 and used to lock the adapter connector 41 relative to the frame adapter 110 when the adapter connector 41 is connected to the frame adapter 110 of the frame 100, and an adapter unlocking mechanism 43 disposed on the adapter connector 41 for linking the unlocking action of the adapter locking mechanism 42.

[0024] As described above, in a bassinet, the adapter connection assembly 4 includes an adapter connector 41 disposed on the enclosure tube assembly 1 or the transition connection plate 22.

The frame linkage unlocking mechanism 45 is configured such that the front enclosure tube 11 is correspondingly linked to unlock during the rotation and folding of the current enclosure tube 11 relative to the rear enclosure tube 12.

[0025] This utility model also provides a children's stroller, including a frame 100 and a bassinet as described above, wherein the frame 100 is provided with a frame adapter 110 for detachable connection with the adapter connection assembly 4.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. In this utility model, the enclosure tube assembly works in conjunction with the supporting assembly through a linkage component. That is, during the folding process of the front and rear enclosure tubes facing each other, the linkage component will simultaneously pull the front bottom plate to fold towards the front enclosure tube and the rear bottom plate to fold towards the rear enclosure tube. This ensures that the folding actions of the enclosure tube assembly and the supporting assembly are completely synchronized, effectively ensuring that the movement trajectory of each component is consistent during the folding process of the bassinet. This avoids misalignment or suspension of the supporting assembly and the enclosure tube assembly, ultimately achieving "layered" storage—the enclosure tubes and the bottom plate fit tightly together, greatly reducing the storage volume and significantly improving space utilization. It also features convenient storage and reliable safety.

[0028] 2. In this utility model, the linkage component rigidly couples the rotation of the enclosure component with the flipping of the bearing component. The user only needs to trigger the enclosure unlocking mechanism with one hand, and the front and rear enclosures will automatically fold towards the center. The front bottom plate, transition connecting plate and rear bottom plate will simultaneously complete the three-section stacking. No secondary action is required throughout the process, avoiding the risk of pinching hands. When unfolding in the reverse direction, it is also done in one step. It has the functions of efficient storage and unfolding, and the operation is simple and convenient.

[0029] 3. In this utility model, the load-bearing component forms a three-section flexible support system of "front-middle-rear" through a rotatable connection structure of the front base plate, transition connecting plate, and rear base plate. This effectively solves the problem of direct hinge between the front and rear base plates in traditional designs, which can easily lead to breakage or deformation at the connection point due to stress concentration during folding. Furthermore, this utility model distributes the rotational load of the front and rear base plates to the transition connecting plate through the segmented connection of the intermediate transition connecting plate. Combined with the "relative fixing" effect of the linkage component on the transition connecting plate, the transition connecting plate moves synchronously with the linkage component but does not directly bear excessive bending moments, effectively reducing stress concentration at each connection point. Simultaneously, the rotatable connection between the front side of the transition connecting plate and the front base plate, and the rear side and the rear base plate, retains the flexibility required for folding the base plate. This allows the load-bearing component to provide a stable load-bearing plane through the rigid support of each base plate when unfolded, balancing folding flexibility with structural strength during use and extending the service life of the sleeping basket.

[0030] 4. To make the folding more compact and minimize the space occupied by the entire sleeping basket after folding, the linkage component can reduce the vertical distance between the rotation axis and the transition connecting plate between the front and rear tubes. Therefore, while the linkage component drives the front and rear bottom plates to fold, the linkage component itself can also fold vertically. Furthermore, it can fold in half while folding vertically, making the entire sleeping basket occupy less space after folding, which is convenient for users to carry and store.

[0031] 5. This utility model, through a multi-link coordinated linkage design, forms a triple linkage link: "front tube - front upper connecting rod - front lower connecting rod - front bottom plate," "rear tube - middle connecting rod - transition connecting plate - rear connecting rod - rear bottom plate," and "front tube - first linkage rod - middle connecting rod - rear tube." This ensures that when the front and rear tubes fold towards each other, the folding angle and speed of the front bottom plate and the front tube, and the rear bottom plate and the rear tube are completely consistent. Specifically, when the front upper connecting rod rotates with the front tube, it directly pulls the front bottom plate to fold synchronously towards the inside of the front tube through the front lower connecting rod; the first linkage rod transmits the rotational force of the front tube's drive unit to the middle connecting rod, causing the rear tube to fold synchronously with the transition connecting plate and the rear bottom plate; the second linkage rod connects the front upper connecting rod and the first linkage rod, further constraining the rotation angle of the front and rear tubes, avoiding movement deviations caused by manufacturing tolerances or external force interference, ultimately achieving the effect of "four-link synchronous movement," significantly improving the consistency of the folding action, and making the folded basket structure more compact.

[0032] 6. This utility model, through a safety mechanism, ensures that the adapter connector and the frame accessory remain connected during the user's adjustment of the bassinet's height, so that the adapter connector can only move up and down and cannot be completely detached from the frame accessory, making the adjustment operation convenient and taking into account safety performance.

[0047] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0048] like Figure 1-13 As shown, this utility model provides a sleeping basket, which includes a surrounding tube assembly 1, a load-bearing assembly 2, a linkage assembly 3, an adapter connection assembly 4, a surrounding tube joint 5, and a surrounding tube unlocking mechanism 55.

[0049] Specifically, the enclosure tube assembly 1 includes a front enclosure tube 11 and a rear enclosure tube 12 that can be folded in opposite directions or unfolded in opposite directions, and the front enclosure tube 11 and the rear enclosure tube 12 are rotatably connected; the supporting assembly 2 includes a front base plate 21, a transition connecting plate 22 and a rear base plate 23, the front side of the transition connecting plate 22 is rotatably connected to the rear side of the front base plate 21, and the rear side of the transition connecting plate 22 is rotatably connected to the front side of the rear base plate 23; the linkage assembly 3 is rotatably connected to the front base plate 21, the rear base plate 23 and the enclosure tube assembly 1 respectively, and the linkage assembly 3 is relatively fixedly connected to the transition connecting plate 22, when the front enclosure tube 11 and the rear enclosure tube 12 fold towards each other. During the folding process, the front bottom plate 21 and the rear bottom plate 23 fold closer to each other relative to the front and rear tubes 11 and 12, respectively. The adapter connecting component 4 is provided on the tube assembly 1, or on the rear bottom plate 23, or on the transition connecting plate 22, for detachable connection with the frame 100. Preferably, the adapter connecting component 4 is provided on the tube assembly 1 or on the rear bottom plate 23 to ensure that when the present invention is connected to a foldable stroller, it can be fully folded to minimize the folded size. The tube joint 5 is located between the front tube 11 and the rear tube 12 and is used to lock the front tube 11 relative to the rear tube 12. The tube unlocking mechanism 55 is provided on the front tube 11 or the rear tube 12 and is linked to the tube joint 5 to release the locking state of the front tube 11 relative to the rear tube 12.

[0050] In this invention, the enclosure tube assembly works in conjunction with the supporting assembly through a linkage component. Specifically, during the folding process of the front and rear enclosure tubes facing each other, the linkage component simultaneously pulls the front bottom plate towards the front enclosure tube and the rear bottom plate towards the rear enclosure tube, ensuring that the folding actions of the enclosure tube assembly and the supporting assembly are completely synchronized. This effectively ensures that the movement trajectories of each component are consistent during the folding process of the bassinet, avoiding misalignment or suspension of the supporting assembly and the enclosure tube assembly. Ultimately, this achieves "layered" storage—the enclosure tubes and the bottom plate fit tightly together, significantly reducing the storage volume and greatly improving space utilization. It also features convenient storage and reliable safety.

[0051] In this utility model, the linkage component rigidly couples the rotation of the enclosure component with the flipping of the load-bearing component. The user only needs to trigger the enclosure unlocking mechanism with one hand, and the front and rear enclosures will automatically fold towards the center. The front bottom plate, transition connecting plate and rear bottom plate will simultaneously complete the three-section stacking. No secondary action is required throughout the process, avoiding the risk of pinching hands. When unfolding in the reverse direction, it is also done in one step. It has the functions of efficient storage and unfolding, and the operation is simple and convenient.

[0052] To achieve a tighter fold and minimize the space occupied by the folded bassinet, the linkage component 3 is further configured such that during the folding process of the front and rear enclosure tubes 11 and 12 approaching each other, the front bottom plate 21 and rear bottom plate 23 fold towards and away from the front and rear enclosure tubes 11 and 12 respectively, and the vertical distance between the rotation axis of the front and rear enclosure tubes 11 and the transition connecting plate 22 is reduced. Figure 6 As shown.

[0053] like Figure 1-10 As shown, the coaxial tube joint 5 includes a front joint block 51 and a rear joint block 52 pivotally connected to each other. The front joint block 51 is connected to the front coaxial tube 11, and the rear joint block 52 is connected to the rear coaxial tube 12. A corresponding driving portion 53 extending towards the rear joint block 52 or the front joint block 51 is formed on either the front joint block 51 or the rear joint block 52. The linkage assembly 3 is rotatably connected to the end of the driving portion 53. In this embodiment, the driving portion 53 directly acts on the linkage assembly 3, effectively simplifying the transmission chain and improving response efficiency. The driving portion 53 is integrally formed or fixedly connected to the front joint block 51, eliminating the need for an additional external transmission mechanism, significantly reducing the lateral / longitudinal dimensions of the front joint block 51, enhancing structural compactness, and saving space.

[0054] like Figure 1-10As shown, a driving part 53 extending towards the rear joint block 52 is formed on the front joint block 51; the linkage assembly 3 includes a front upper connecting rod 31, a front lower connecting rod 32, a middle connecting rod 33, a rear connecting rod 34, a first linkage rod 35, and a second linkage rod 36; the upper end of the front upper connecting rod 31 is rotatably connected to the front bulkhead tube 11, the lower end of the front upper connecting rod 31 is rotatably connected to the upper end of the front lower connecting rod 32, and the lower end of the front lower connecting rod 32 is rotatably connected to the front bottom plate 21; the upper end of the middle connecting rod 33 is rotatably connected to the rear bulkhead tube 12, and the middle... The lower end of the intermediate connecting rod 33 is fixedly connected to the transition connecting plate 22; the upper end of the rear connecting rod 34 is rotatably connected to the rear casing tube 12, and the lower end of the rear connecting rod 34 is rotatably connected to the rear bottom plate 23; the front end of the first linkage rod 35 is rotatably connected to the drive unit 53, and the rear end of the first linkage rod 35 is rotatably connected to the middle or upper part of the intermediate connecting rod 33; the front end of the second linkage rod 36 is rotatably connected to the middle or lower part of the front upper connecting rod 31, and the rear end of the second linkage rod 36 is rotatably connected to the middle or front part of the first linkage rod 35. This embodiment employs a multi-link coordinated design to form a triple linkage system: "front tube - front upper link - front lower link - front bottom plate," "rear tube - middle link - transition connecting plate - rear link - rear bottom plate," and "front tube - first linkage rod - middle link - rear tube." This ensures that when the front and rear tubes fold towards each other, the folding angle and speed of the front bottom plate and the front tube, and the rear bottom plate and the rear tube, are completely consistent. Specifically, as the front upper link rotates with the front tube, it directly pulls the front bottom plate to fold synchronously towards the inside of the front tube via the front lower link. The first linkage rod transmits the rotational force of the front tube's drive unit to the middle link, causing the rear tube to fold synchronously with the transition connecting plate and the rear bottom plate. The second linkage rod connects the front upper link and the first linkage rod, further constraining the rotation angle of the front and rear tubes, avoiding movement deviations caused by manufacturing tolerances or external force interference. Ultimately, this achieves the effect of "four-link synchronous movement," significantly improving the consistency of the folding action and making the folded basket structure more compact.

[0055] In another embodiment, a drive portion 53 extending forward from the joint block 51 is formed on the rear joint block 52; at this time, the upper end of the front upper connecting rod 31 is rotatably connected to the rear bulkhead tube 12, the lower end of the front upper connecting rod 31 is rotatably connected to the upper end of the front lower connecting rod 32, and the lower end of the front lower connecting rod 32 is rotatably connected to the rear bottom plate 23; the upper end of the middle connecting rod 33 is rotatably connected to the front bulkhead tube 11, and the lower end of the middle connecting rod 33 is relatively fixedly connected to the transition connecting plate 22. The upper end of the rear connecting rod 34 is rotatably connected to the front bulkhead tube 11, and the lower end of the rear connecting rod 34 is rotatably connected to the front bottom plate 21; the front end of the first linkage rod 35 is rotatably connected to the drive unit 53, and the rear end of the first linkage rod 35 is rotatably connected to the middle or upper part of the intermediate connecting rod 33; the front end of the second linkage rod 36 is rotatably connected to the middle or lower part of the upper front connecting rod 31, and the rear end of the second linkage rod 36 is rotatably connected to the middle or front part of the first linkage rod 35.

[0056] like Figure 1 , 8 As shown in Figure -10, for reliable locking and convenient unlocking, the enclosure joint 5 further includes a joint locking assembly 54 disposed between the front joint block 51 and the rear joint block 52 for positioning the front joint block 51 relative to the rear joint block 52. The enclosure unlocking mechanism 55 is used to trigger the unlocking action of the joint locking assembly 54 to release the locking state of the front joint block 51 relative to the rear joint block 52. The joint locking assembly 54 includes a joint locking part 541 disposed on the rear joint block 52 and a joint locking member 542 movably disposed on the front joint block 51 for locking and engaging with the joint locking part 541. A joint locking elastic member 543 is provided between the joint locking member 542 and the front joint block 51 for driving the joint locking member 542 to elastically reset. The enclosure unlocking mechanism 55 is used to trigger the unlocking action of the joint locking member 542 to release the locking state of the front joint block 51 relative to the rear joint block 52. The enclosure unlocking mechanism 55 includes an enclosure unlocking handle 551 movably mounted on the front enclosure 11. The enclosure unlocking handle 551 is connected to the joint locking member 542 via an enclosure unlocking pull rope 552. During unlocking, the user only needs to pull the enclosure unlocking handle 551 with one hand, and the enclosure unlocking pull rope 552 simultaneously drives the joint locking member 542 to disengage from the joint locking part 541, releasing the locking state of the front joint block 51 relative to the rear joint block 52, thereby unlocking the front and rear enclosures. The joint locking elastic member 543 ensures that the joint locking member 542 maintains an elastic locking engagement with the joint locking part 541, ensuring reliable locking.

[0057] like Figure 8-13As shown, the adapter connection assembly 4 includes an adapter connector 41 disposed on the enclosure assembly 1 or the transition connection plate 22, an adapter locking mechanism 42 disposed on the adapter connector 41 and used to lock the adapter connector 41 relative to the frame adapter 110 when the adapter connector 41 is connected to the frame adapter 110 of the frame 100, and an adapter unlocking mechanism 43 disposed on the adapter connector 41 for triggering the unlocking action of the adapter locking mechanism 42. In this embodiment, the adapter connector 41 is sleeved on the frame adapter 110 for easy assembly and disassembly.

[0058] like Figure 8-13 As shown, for reliable locking and unlocking linkage, the adapter locking mechanism 42 includes an adapter locking member 421 that is laterally slidable on the adapter connector 41 and used for locking and engaging with the adapter locking part 111 on the frame adapter 110; the adapter unlocking mechanism 43 includes an adapter unlocking linkage block 431 that is vertically slidable on the adapter connector 41, the adapter unlocking linkage block 431 is provided with an adapter unlocking inclined part 432 for driving the adapter locking member 421 to slide accordingly, and an adapter unlocking elastic member 433 is provided between the adapter unlocking linkage block 431 and the adapter connector 41 for driving the adapter unlocking linkage block 431 to elastically reset; the adapter unlocking mechanism 43 also includes an adapter unlocking push rod 434 that is slidably provided on the adapter connector 41 for pushing the adapter unlocking linkage block 431 to unlock. During unlocking, pressing the adapter unlocking push rod 434 vertically slides relative to the adapter connector 41. The adapter unlocking push rod 434 presses against the adapter unlocking linkage block 431, which slides vertically accordingly. The adapter unlocking inclined part 432 drives the adapter locking rod of the adapter locking member 421, causing the adapter locking member 421 to slide horizontally accordingly. This separates the locking end of the adapter locking member 421 from the adapter locking part 111, thereby unlocking the locked state of the adapter connector 41 relative to the frame adapter 110. In this embodiment, the design of linkage unlocking through rigid parts effectively solves the problems of laborious operation, easy jamming, inaccurate positioning, and poor compatibility of traditional unlocking methods. It has the characteristics of efficient force transmission, stability and reliability, accurate positioning, and durable compatibility.

[0059] like Figure 7-13As shown, the adapter locking mechanism 42 is configured to lock the adapter connector 41 at different heights relative to the frame adapter 110. The adapter connector 41 is provided with a safety mechanism 44 to prevent separation between the adapter connector 41 and the frame adapter 110 during the lifting and lowering adjustment process. The safety mechanism 44 is configured to be linked to the unlocking action of the adapter locking mechanism 42. In this embodiment, the adapter locking member 421 is configured to engage with the corresponding adapter locking part 111 to allow the adapter connector 41 to be lifted and lowered relative to the frame adapter 110. The safety mechanism ensures that the adapter connector remains connected to the frame adapter during the adjustment of the bassinet height, preventing the adapter connector from completely disengaging from the frame adapter. This makes the adjustment operation convenient and ensures safety.

[0060] like Figure 7-13 As shown, the safety mechanism 44 includes a safety sliding block 441 slidably mounted on the adapter connector 41 and capable of pushing the adapter unlocking linkage block 431 to perform an unlocking action. The safety sliding block 441 is provided with a safety blocking block 442 for blocking and engaging with the adapter blocking portion 112 at the upper end of the frame adapter 110. The safety blocking block 442 is also configured to slide out from the blocking clearance notch 113 at the upper end of the frame adapter 110. The safety blocking block 442 is slidably mounted on the safety sliding block 441, and a safety elastic element 443 is provided between the safety blocking block 442 and the safety sliding block 441 to drive the safety blocking block 442 to elastically reset. During adjustment, the user presses the adapter unlocking top rod 434 and slides it vertically relative to the adapter connector 41. The adapter unlocking top rod 434 presses against the adapter unlocking linkage block 431 and slides vertically accordingly. The adapter unlocking inclined part 432 drives the adapter locking rod of the adapter locking member 421 to slide horizontally accordingly, thereby separating the locking end of the adapter locking member 421 from the adapter locking part 111. Then, according to the usage requirements, the adapter connector 41 is adjusted to move up or down relative to the frame adapter 110. When the desired position is reached, the pressing force on the adapter unlocking top rod 434 is released. At this time, the adapter unlocking linkage block 431 slides upward and resets under the elastic force of the adapter unlocking elastic member 433. That is, the adapter unlocking inclined part 432 drives the adapter locking rod of the adapter locking member 421 to slide horizontally accordingly, so that the locking end of the adapter locking member 421 is inserted into the adapter locking part 111. During the above adjustment process, the safety blocking block 442 is aligned with the adapter blocking part 112 and is blocked and restricted, so that the adapter connector can only move up and down and cannot be completely separated from the frame adapter.

[0061] When it is necessary to remove the adapter connector from the frame adapter, the user presses the safety sliding block 441 to slide it, which causes the adapter unlocking linkage block 431 to slide vertically accordingly. The adapter unlocking inclined part 432 drives the adapter locking rod of the adapter locking member 421 to slide horizontally accordingly, thereby separating the locking end of the adapter locking member 421 from the adapter locking part 111. At the same time, the safety blocking block 442 slides accordingly with the pressing of the safety sliding block 441, causing the safety blocking block 442 to be misaligned with the adapter blocking part 112 and engage with the blocking clearance notch 113. Then the user operates the adapter connector to slide upward relative to the frame adapter until the bassinet is removed from the frame.

[0062] To facilitate disassembly, the frame adapter 110 is equipped with a safety blocking protrusion extending vertically. An adapter blocking portion 112 and a blocking clearance notch 113 are located on either side of the safety blocking protrusion. The safety blocking block 442 has a blocking end and a blocking bevel for engaging with the safety blocking protrusion. During unlocking, the blocking bevel engages with the safety blocking protrusion, forcing the safety blocking block 442 to retract accordingly for unlocking. When the safety blocking block 442 engages with the blocking clearance notch 113, the blocking end engages with the safety blocking protrusion to restrict the sliding return of the safety sliding block 441. Therefore, the user does not need to continuously press the safety sliding block 441; that is, even when the pressure on the safety sliding block 441 is released, the safety blocking block 442 remains engaged with the blocking clearance notch 113, facilitating subsequent disassembly. This design is reasonable.

[0063] like Figure 7-11As shown, for ease of operation and better linkage of frame unlocking, the adapter connection assembly 4 includes an adapter connector 41 disposed on the enclosure tube assembly 1 or the transition connection plate 22. The adapter connector 41 is provided with a frame linkage unlocking mechanism 45 for unlocking the frame locking mechanism 120 of the linkage frame 100. The frame linkage unlocking mechanism 45 is configured such that the front enclosure tube 11 is correspondingly linked to unlock during the rotation and folding of the current enclosure tube 11 relative to the rear enclosure tube 12. The frame linkage unlocking mechanism 45 includes a frame linkage unlocking component 451 that is laterally slidable on the adapter connector 41 and used to link the unlocking action of the frame locking mechanism 120, and a frame linkage slider 452 that is vertically slidable on the adapter connector 41 and used to drive the frame linkage unlocking component 451 to slide accordingly. The frame linkage slider 452 and the frame linkage unlocking component 451 are respectively provided with frame linkage unlocking inclined surfaces 453 that can unlock and cooperate with each other. The rear joint block 52 is provided with a movably mounted frame linkage block 455, and the frame linkage block 455 is linked by a pull rope connected to the frame linkage slider 452. The front joint block 51 is provided with a frame linkage drive component 454 that is used to link the unlocking action of the frame linkage block 455 during the rotation and folding of the front enclosure tube 11 relative to the rear enclosure tube 12. During the rotation and folding of the current enclosure tube 11 relative to the rear enclosure tube 12, the frame linkage drive component 454 drives the frame linkage block 455 to move accordingly. The frame linkage block 455 drives the frame linkage slider 452 to slide upward relative to the adapter connector 41 through the linkage pull rope. The frame linkage slider 452 and the frame linkage unlocking inclined surface 453 on the frame linkage unlocking component 451 cooperate with each other to drive the frame linkage unlocking component 451 to slide accordingly, so that the frame linkage unlocking component 451 presses against the frame unlocking component of the frame locking mechanism 120 provided on the frame adapter, thereby causing the frame unlocking component to directly or indirectly unlock the frame locking mechanism 120.

[0064] like Figure 1-6As shown in Figures 9 and 10, for reliable locking, convenient unlocking, and easy lifting, a support rod 6 is also included. The end of the support rod 6 is movably connected to the end of the rear tube 12. A support rod locking mechanism 61 for locking the support rod 6 relative to the rear tube 12 and a support rod unlocking mechanism 62 for releasing the support rod locking mechanism 61 are provided between the support rod 6 and the rear tube 12. The support rod locking mechanism 61 includes, but is not limited to, a locking groove 611 provided on the lower end of the support rod 6 and the opposite side of the rear joint block 52 of the rear tube 12, and a locking gear 612 slidably provided between the support rod 6 and the rear joint block 52 and capable of simultaneously engaging the locking groove 611 on the support rod 6 and the rear joint block 52. A gear elastic element is provided between the locking gear 612 and the rear joint block 52 for driving the locking gear 612 to elastically reset. The support rod unlocking mechanism 62 includes, but is not limited to, a support rod unlocking button 621 slidably disposed on the lower end side of the support rod 6, and an unlocking push rod 622 for pushing the locking gear 612 to perform the corresponding unlocking action is provided on the inner side of the support rod unlocking button 621.

[0065] like Figure 1-13 As shown, this utility model discloses a children's stroller, including a frame 100 and a bassinet as described above. The frame 100 is provided with a frame adapter 110 for detachable connection with the adapter connection component 4. By integrating an innovative bassinet structure, it achieves systematic advantages in terms of storage portability, structural safety, scene adaptability, ease of operation, and durability. It effectively solves the problems of traditional strollers such as "taking up space when stored, cumbersome operation, poor adaptability, and many safety hazards," making it a new type of children's stroller that balances functionality, practicality, and user experience.
