Description

Technical Field

[0001] This invention relates to the field of cradle technology, and in particular to infant cradles. Background Technology

[0002] Newborns sleep for extended periods, sometimes exceeding 20 hours a day, but this sleep is fragmented, ranging from a few minutes to several hours. Parents need to frequently rock them to sleep, and prolonged rocking can easily lead to strain issues such as "mommy's elbow" or "nanny's elbow." Therefore, sleep aids that can mimic the gentle rocking motions of an adult are of significant practical value. Currently, similar products on the market mainly fall into four categories:

[0003] Fixed cribs: These products can only be used after the baby is asleep. They do not have an active sleep-inducing function, and parents still need to hold and soothe the baby during the sleep-inducing process.

[0004] Vertical (gravity) pendulum-style cradle: This type of product relies on gravity to create a pendulum-like rocking motion. At the two lateral ends of the reciprocating swing, centrifugal inertia may cause the baby to roll sideways, thus requiring a safety belt to secure the baby, posing a safety hazard and affecting comfort.

[0005] Four-corner rocking cribs: These products have a support pillar at each of the four corners, with compression springs inside. They work by using mechanical force to pull the crib down, and the springs rebounding upwards to create rocking motion. Because the direction of the compression spring's support force is uncertain compared to the direction of movement, the support pillars are needed for guidance. When the baby's or other object's center of gravity deviates from the center of the four support pillars, the force on each pillar becomes uneven. If this uneven force exceeds the self-locking angle of the guide pillars, the pillars may jam, preventing the crib from rocking.

[0006] Hanging baby cradles: These products use springs to suspend the crib from a power source, utilizing the interaction of springs and gravity to gently rock the crib up and down. A power cord provides additional energy to maintain the set amplitude. Their drawbacks include the need for external suspension devices such as tripods, gantry frames, or ceiling supports. Using a frame-type suspension results in a high center of gravity, making it prone to tipping over and requiring a large footprint; direct ceiling mounting necessitates structural modifications. Furthermore, the strap or fabric sling structure makes placing and removing the baby inconvenient.

[0007] It is evident that existing baby crib products each have significant drawbacks: fixed cribs lack a soothing function; gravity pendulum cribs pose a safety hazard due to centrifugal force; four-corner support cribs are prone to jamming and locking; and hanging cribs rely on external suspension devices and are inconvenient to access. Currently, there is a lack of a baby crib that combines the advantages of fixed cribs, such as stability, low center of gravity, and easy access, while also providing a safe, stable, and multi-mode rocking soothing function.

[0008] Therefore, how to provide an infant cradle that can maintain the stability and convenience of a fixed infant crib while achieving a safe, stable, and multi-mode rocking function to soothe the baby to sleep is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0009] In view of this, the present invention proposes an infant cradle bed, which aims to solve at least one of the above-mentioned technical problems.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides an infant cradle, comprising: bedstead, The cradle bed and the suspension assembly, wherein the head and tail of the cradle bed can be independently raised, lowered and rocked within the bed frame via the suspension assembly; A headboard limiting component is provided on the bed frame and can abut against the head of the cradle bed to limit the descent of the head of the cradle bed; A footboard limiting component is provided on the bed frame and can abut against the foot of the cradle bed to limit the descent of the footboard. A drive mechanism, mounted on the bed frame and connected to the head and tail of the cradle bed, is used to independently or synchronously drive the head and tail of the cradle bed to lift.

[0011] In use, the baby cradle of this invention suspends the head and tail of the cradle independently within the bed frame via a suspension assembly. Head and tail limiting components are respectively mounted on the bed frame and can selectively engage with the head and / or tail of the cradle, thus enabling multiple usage modes: Fixed mode: When both the head and tail limiting components are engaged with the corresponding head and tail of the cradle, the descent of the head and tail of the cradle is restricted, thus locking it into a rigid support state, transforming it into a fixed baby cradle for safe placement or removal of the baby. Single-sided rocking mode: When only the head limiting component engages with the head of the cradle, restricting the head's descent, while the tail limiting component is not engaged and the tail can descend freely, the drive mechanism can independently drive the tail of the cradle to move up and down, achieving a single-sided rocking sleep-inducing method. Overall lifting and rocking mode: When neither the head nor foot limiters are engaged (neither the head nor the foot is restricted from descending), the drive mechanism can simultaneously raise and lower the head and foot of the cradle, achieving an overall lifting and rocking motion for soothing the baby to sleep. Users can flexibly choose between a fixed mode, a single-side rocking mode, or an overall lifting and rocking mode according to the baby's actual needs and preferences, significantly improving the flexibility and adaptability of use and effectively reducing the burden on parents in putting the baby to sleep.

[0012] As a further improvement to the above technical solution, the bed frame includes a bed base frame, a head support frame, and a tail support frame; the head support frame and the tail support frame are both located above the bed base frame; the lower end of the head support frame is connected to the head of the bed base frame, and the lower end of the tail support frame is connected to the tail of the bed base frame; the cradle bed body can be disposed above the bed base frame and corresponding to the head support frame and the tail support frame; the head and tail of the cradle bed body can be independently raised, lowered, and rocked above the head support frame and the tail support frame through the suspension assembly; the headstock limiting component is disposed on the head support frame; the tailstock limiting component is disposed on the tail support frame.

[0013] The beneficial effects of the above technical solution are as follows: By setting up a bed base frame and head support frames and tail support frames fixedly connected at both ends, a stable split support structure is formed, which improves the structural stability of the whole machine during operation; the cradle bed is located between the two support frames, and its head and tail are suspended from the top of the support frames one by one through the suspension components, ensuring the vertical transmission of suspension force and the balance of left and right movement, and avoiding movement interference; the head limit component and the tail limit component are respectively set on the head support frame and the tail support frame, directly facing the head and tail of the cradle bed, simplifying installation and adjustment, and ensuring that vertical and uniform rigid support can be provided when limiting; at the same time, the two limit components do not interfere with each other and operate independently, so that the switching between fixed mode, single-sided rocking mode and overall lifting and rocking mode is more reliable and accurate, further enhancing the practicality and safety of the whole machine.

[0014] As a further improvement to the above technical solution, the head support frame includes a head upright, a head upright, and a head crossbeam; the head upright and the head upright are parallel to each other and their lower ends are hinged to the left and right sides of the top of the head of the bed frame; the two ends of the head crossbeam in the length direction are vertically fixed to the upper ends of the head upright and the head upright. The tail support frame includes a tail upright, a tail upright, and a tail crossbeam; the tail upright and the tail upright are parallel to each other and their lower ends are hinged to the left and right sides of the top of the tail of the bed frame; the two ends of the tail crossbeam are vertically fixed to the upper ends of the tail upright and the tail upright. The beneficial effects of the above technical solution are as follows: The head support frame and the tail support frame are each composed of two parallel and opposite uprights and a top crossbeam, forming a stable portal frame structure. The lower ends of head upright one, head upright two, tail upright one, and tail upright two are hinged to the bed base frame, giving the support frame high structural strength and stability in the upright state, and enabling it to reliably support the weight of the cradle and the baby. The head crossbeam and tail crossbeam provide clear installation positions for the drive mechanism and suspension springs, facilitating the assembly of various components and the realization of their functions.

[0015] As a further improvement to the above technical solution, the drive mechanism includes a head drive mechanism and a tail drive mechanism; the head drive mechanism is installed on the head crossbeam and connected to the head of the cradle bed through a transmission rope, for driving the head of the cradle bed to rise and fall; the tail drive mechanism is installed on the tail crossbeam and connected to the tail of the cradle bed through a transmission rope, for driving the tail of the cradle bed to rise and fall.

[0016] The beneficial effects of the above technical solution are as follows: By mounting the head drive mechanism on the head crossbeam and the tail drive mechanism on the tail crossbeam, placing them at the highest point of the support frame, the transmission rope can extend vertically downwards to connect to the head and tail of the cradle, achieving vertical traction drive. This layout minimizes the transmission path of the driving force, reduces energy loss and friction during transmission, improves the accuracy and response speed of rocking control, and makes the installation position of the drive mechanism more concealed, without affecting the neat appearance.

[0017] As a further improvement to the above technical solution, the head support frame and the tail support frame can be flipped and folded around their lower hinge axis and placed on top of the bed frame; the head support frame and the tail support frame can also be flipped to an upright state and locked in the upright state by a support positioning mechanism.

[0018] The beneficial effects of the above technical solution are as follows: the head support frame and tail support frame can be flipped and folded around their lower hinge axis and placed horizontally on top of the bed base frame, allowing the entire cradle to be folded and stored during transportation or when not in use, significantly reducing its volume and facilitating packaging, transportation, and storage. When flipped to the upright position, it is locked by a support positioning mechanism to ensure that the support frame remains stable during rocking and will not fold accidentally. This foldable structure, while ensuring usability, greatly improves the product's portability and space utilization, solving the problems of existing hanging basket-style cribs having a large footprint and being difficult to store.

[0019] As a further improvement to the above technical solution, the support and positioning mechanism includes a first longitudinal support rod and a second longitudinal support rod; the two ends of the first longitudinal support rod can be detachably and vertically connected to the outer peripheral walls of the first head support rod and the first tail support rod, and the two ends of the second longitudinal support rod can be detachably and vertically connected to the outer peripheral walls of the second head support rod and the second tail support rod, so as to position and support the head support frame and the tail support frame in an upright state.

[0020] The beneficial effects of the above technical solution are as follows: The support and positioning mechanism connects and locks the head support frame and the tail support frame through longitudinal support rod one and longitudinal support rod two. The two longitudinal support rods are arranged horizontally and perpendicular to head upright rod one, head upright rod two, tail upright rod one, and tail upright rod two, forming a stable rigid support structure. This ensures that the head support frame and the tail support frame will not experience relative displacement or folding due to external forces or shaking when in an upright state. Simultaneously, the longitudinal support rods adopt a detachable connection method, facilitating quick installation and disassembly, further improving the convenience of folding and storage.

[0021] As a further improvement to the above technical solution, the bed frame is a rectangular frame structure and each of its four corners is provided with a limiting hinge seat; the lower ends of the head upright, the head upright, the tail upright, and the tail upright are hinged one-to-one on the four limiting hinge seats; the limiting hinge seats have a limiting part that restricts the head upright, the head upright, the tail upright, and the tail upright from continuing to rotate when they are rotated to the vertical state.

[0022] The beneficial effects of the above technical solution are as follows: The bed frame adopts a rectangular frame structure, with limiting hinge seats at all four corners. Each limiting hinge seat has a limiting part. When the head upright one, head upright two, tail upright one, and tail upright two are flipped to a vertical position, the limiting part abuts against the locking part on the outer periphery of the hinge joint at the lower end of the corresponding upright, restricting further forward flipping and thus precisely locking each upright in a vertical position. This structure not only ensures the stability and safety of the support frame in the vertical state but also, through the abutting action of the limiting part, prevents the uprights from excessively flipping due to inertia or external force during shaking, improving the reliability of use.

[0023] As a further improvement to the above technical solution, the suspension assembly includes a head suspension spring and a tail suspension spring; suspension component one and suspension component two are fixed to the top two sides of the head of the cradle bed, and suspension component three and suspension component four are fixed to the top two sides of the tail. The first and second suspension components are located between the first and second head uprights, and can slide or roll along the length of the first and second head uprights respectively to fit against their opposite sidewalls. The suspension component three and suspension component four are located between the tail upright one and the tail upright two, and can slide or roll along the length direction of the tail upright one and the tail upright two respectively to fit against their opposite side walls. Both the head suspension spring and the tail suspension spring are in two sets; the two sets of head suspension springs are arranged along the height direction of the head support frame, and their lower ends are hooked to the tops of the first suspension component and the second suspension component, respectively, and their upper ends are hooked to the bottom of the head crossbeam. The two sets of tail suspension springs are arranged along the height direction of the tail support frame, with their lower ends hooked to the tops of the suspension component three and the suspension component four, and their upper ends hooked to the bottom of the tail crossbeam.

[0024] The beneficial effects of the above technical solution are as follows: Suspension components one, two, three, and four can slide or roll along the length of their corresponding uprights, conforming to the opposite sidewalls of each upright, thus providing lateral guidance. This prevents the cradle frame from directly rubbing against the uprights of the support frame during up-and-down rocking, maintaining smooth and quiet movement. Both the head and tail suspension springs are in two sets, hooked to the top of the suspension components and the bottom of the crossbeam respectively, forming four suspension points. This ensures even distribution of suspension force and more stable rocking. Furthermore, the two sets of springs can be selected and configured according to the baby's weight, ensuring the closeness and adaptability of the rocking frequency.

[0025] As a further improvement to the above technical solution, both the first and second suspension components are provided with a locking groove 1 at their bottoms; both the third and fourth suspension components are provided with a locking groove 2 at their bottoms. The two ends of the headboard limiting component are slidably sleeved on the headboard support one and the headboard support two respectively; the headboard limiting component can slide and rise along the length direction of the headboard support one and the headboard support two, and its outer peripheral wall is embedded in the locking groove one to support and limit the descent of the head of the cradle bed. The two ends of the footboard limiting component are slidably sleeved on the first and second tailboard uprights respectively; the footboard limiting component can slide upward along the length direction of the first and second tailboard uprights and its outer peripheral wall is embedded in the second locking groove to support and limit the descent of the footboard of the cradle.

[0026] The beneficial effects of the above technical solution are as follows: the two ends of the headboard and footboard limiting components are slidably sleeved on the corresponding uprights, allowing them to slide upwards along the length of each upright and embed their outer peripheral walls into the locking grooves at the bottom of suspension components one, two, three, and four, thus forming rigid support. This cooperation method creates a stable mechanical connection between the limiting components and the suspension components, effectively supporting and limiting the descent of the crib, achieving a stable state for the fixed crib. When switching to rocking mode, simply lower the limiting components out of the locking grooves; the operation is simple and quick. In the single-sided rocking soothing mode, the outer peripheral wall of the headrest limiting component located on the head support and fixing side is embedded in the corresponding locking groove. While supporting the head of the cradle to prevent it from falling, the outer peripheral wall of the headrest limiting component can rotate relative to it in the locking groove around its circumference, forming a rotating pair to adapt to the slight angle changes of the head of the bed during single-sided rocking, avoiding rigid jamming, thus providing stable support while taking into account the flexibility of rocking.

[0027] As a further improvement to the above technical solution, the bottom of the cradle bed is provided with a bed depth adjustment part, which can be extended downward along the height direction of the cradle bed to adjust the depth of the cradle bed.

[0028] The beneficial effects of the above technical solution are as follows: The bottom of the cradle is equipped with a depth adjustment section that can be extended downwards along the height of the cradle to adjust its depth. This design allows the cradle to flexibly adjust its depth to accommodate the growth needs of infants at different ages: for smaller infants who cannot yet stand up, the depth adjustment section can be folded down to a shallow position, making it easier for parents to pick them up and care for them; for larger infants who can stand or move around, the depth adjustment section can be extended to a deeper position, increasing the side wall height and effectively preventing the infant from falling out of the cradle when standing, thus improving safety. A single cradle structure can cover multiple usage scenarios, reducing the cost for users who purchase multiple cribs.

[0029] As a further improvement to the above technical solution, the cradle bed includes a cylindrical bed frame and a ring bed zipper; the bed depth adjustment part includes a cylindrical flexible connecting part integrally connected to and communicating with the lower end opening of the cylindrical bed frame and a bed base plate that seals the lower end opening of the cylindrical flexible connecting part; the ring bed zipper includes a first chain belt and a second chain belt that cooperate with each other; the first chain belt is fixed to the outer periphery of the lower end opening of the cylindrical bed frame; the second chain belt is fixed to the outer periphery of the bed base plate; When chain belt one and chain belt two are pulled together, the cylindrical flexible connecting part is folded and stored inside the bottom of the cylindrical bed, and the bed base plate blocks the lower end of the cylindrical bed, and the cradle bed is in the first depth state; when chain belt one and chain belt two are separated, the cylindrical flexible connecting part unfolds downward to the fully unfolded state, the bed base plate is suspended from the lower end of the fully unfolded cylindrical flexible connecting part, and the cradle bed is in the second depth state.

[0030] The beneficial effects of the above technical solution are as follows: the depth of the cradle bed can be easily switched by opening and closing the zipper. When chain one and chain two are closed, the cylindrical flexible connecting part is folded and stored inside the bottom of the cylindrical bed, and the bed base plate seals the lower end of the cylindrical bed, putting the cradle bed in a shallow state. When the chain is opened, the cylindrical flexible connecting part unfolds downwards to a fully unfolded state, and the bed base plate is suspended below the fully unfolded cylindrical flexible connecting part, putting the cradle bed in a deep state. The bed depth can be easily switched by opening and closing the zipper; the operation is simple, requires no disassembly of any parts, and significantly improves the convenience and flexibility of use.

[0031] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an infant cradle bed, which has the following advantages and beneficial effects.

[0032] 1. This invention uses a suspension spring and a sliding limiting component to achieve flexible switching between three modes: fixed crib, single-sided rocking to lull to sleep, and overall lifting and rocking, which can meet the needs of different usage scenarios; and retains the advantages of traditional fixed cribs such as low center of gravity, stability and safety, and convenient access to the baby; users can choose between two rocking modes for lulling to sleep: single-sided up and down rocking and overall lifting and rocking.

[0033] 2. The support frame of the present invention can be flipped and folded around the hinge axis and placed on the top of the bed frame, which significantly reduces the volume and facilitates transportation and storage.

[0034] 3. The bottom of the bed frame of the present invention is provided with a depth adjustment part. When the bed is shallow, it is easy to pick up and care for the baby. When the bed is deep, the height of the side wall is increased, which effectively prevents the baby from falling off when standing and improves safety.

[0035] 4. This invention uses a four-corner suspension spring system, where the suspension components slide or roll against the uprights, preventing the bed frame from rubbing against the support frame. This allows for free up-and-down rocking while maintaining smooth and quiet rocking. It also provides lateral guidance, eliminating lateral centrifugal force when rocking the baby to sleep, preventing the baby from rolling to the side. The suspension springs can be configured according to the baby's weight to ensure adaptability to the rocking frequency.

[0036] 5. In the single-sided rocking mode, the limiting component is embedded in the locking groove to form a rotating pair, which supports the head while adapting to angle changes, avoiding rigid jamming, and balancing stability and flexibility. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] According to embodiments of the present invention, such as Figures 1 to 14 As shown, the baby cradle includes: bedstead, The cradle bed 4 and the suspension assembly: the head and tail of the cradle bed 4 can be independently raised, lowered and rocked within the bed frame via the suspension assembly; The headboard limiting component 7 is installed on the bed frame and can abut against the head of the cradle bed 4 to limit the descent of the head of the cradle bed 4; The footboard limiting component 8 is installed on the bed frame and can abut against the foot of the cradle bed 4 to limit the descent of the foot of the cradle bed 4. The drive mechanism is mounted on the bed frame and is connected to the head and tail of the cradle bed 4 for independent or synchronous driving of the head and tail of the cradle bed 4.

[0058] In this embodiment, the baby cradle 4 is suspended from the bed frame by a suspension assembly, allowing both the head and tail of the cradle body 4 to be independently raised and lowered, rocking back and forth. The headrest limiting component 7 and the footrest limiting component 8 are respectively mounted on the bed frame, selectively engaging with the head and / or tail of the cradle body 4 to achieve multiple usage modes. Fixed mode: When both the headrest limiting component 7 and the footrest limiting component 8 engage with the corresponding head and tail of the cradle body 4, the descent of both the head and tail of the cradle body 4 is restricted, thus locking it into a rigid support state, transforming it into a fixed baby cradle for safe placement or removal of the baby. Single-sided rocking mode: When only the headrest limiting component 7 engages with the head of the cradle body 4, restricting the head's descent, while the footrest limiting component 8 does not engage with the tail, allowing the tail to descend freely, the drive mechanism can independently drive the tail of the cradle body 4 to rise and fall, rocking back and forth, achieving a single-sided rocking soothing method. Overall lifting and rocking mode: When neither the headboard limiting component 7 nor the footboard limiting component 8 is in contact (neither the head nor the foot is restricted from descending), the drive mechanism can simultaneously drive the head and foot of the cradle 4 to rise and fall simultaneously, achieving an overall lifting and rocking method for soothing the baby to sleep. Users can flexibly choose the fixed mode, single-sided rocking mode, or overall lifting and rocking mode according to the baby's actual needs and preferences, significantly improving the flexibility and adaptability of use and effectively reducing the burden on parents in putting the baby to sleep.

[0059] In some embodiments, the bed frame includes a bed base frame 1, a head support frame 2, and a tail support frame 3; both the head support frame 2 and the tail support frame 3 are located above the bed base frame 1; the lower end of the head support frame 2 is connected to the head of the bed base frame 1, and the lower end of the tail support frame 3 is connected to the tail of the bed base frame 1; the cradle bed 4 can be disposed above the bed base frame 1 and between the head support frame 2 and the tail support frame 3; the head and tail of the cradle bed 4 can be independently raised and lowered and rocked by a suspension assembly; the head limit component 7 is disposed on the head support frame 2; and the tail limit component 8 is disposed on the tail support frame 3.

[0060] In some embodiments, the drive mechanism includes a head drive mechanism 9 and a tail drive mechanism 10; the head drive mechanism 9 is mounted on the head crossbeam 23 and connected to the head of the cradle bed 4 via a transmission rope, for driving the head of the cradle bed 4 to rise and fall; the tail drive mechanism 10 is mounted on the tail crossbeam 33 and connected to the tail of the cradle bed 4 via a transmission rope, for driving the tail of the cradle bed 4 to rise and fall.

[0061] Specifically, both the head beam 23 and the tail beam 33 are shell structures with a through hole at the lower center for threading the drive rope; the head drive mechanism 9 is mounted on a mounting plate inside the head beam 23; the tail drive mechanism 10 is mounted on a mounting plate inside the tail beam 33. The head drive mechanism 9 and the tail drive mechanism 10 have the same structure and can be designed with reference to existing technology, so they will not be described in detail here.

[0062] The head drive mechanism 9 is mounted on the head crossbeam 23, and the tail drive mechanism 10 is mounted on the tail crossbeam 33, positioned at the highest point of the support frame. This allows the transmission rope to extend vertically downwards to connect to the head and tail of the cradle bed 4, achieving vertical traction drive. This layout minimizes the transmission path of the driving force, reduces energy loss and friction during transmission, improves the accuracy and response speed of rocking control, and makes the installation position of the drive mechanism more concealed, without affecting the neat appearance.

[0063] In some embodiments, the suspension assembly includes a head suspension spring 5 and a tail suspension spring 6.

[0064] Both the head support frame 2 and the tail support frame 3 are located above the bed base frame 1; the lower end of the head support frame 2 is connected to the head of the bed base frame 1, and the lower end of the tail support frame 3 is connected to the tail of the bed base frame 1.

[0065] The cradle frame 4 can be installed above the bed base frame 1 and between the head support frame 2 and the tail support frame 3.

[0066] The upper end of the head suspension spring 5 is suspended from the top of the head support frame 2, and the lower end is suspended from the head of the cradle bed 4. The upper end of the tail suspension spring 6 is suspended from the top of the tail support frame 3, and the lower end is suspended from the tail of the cradle bed 4.

[0067] The headrest limiting component 7 is slidably mounted on the head support frame 2 and can rise and abut against the head of the cradle bed 4 to limit the descent of the head of the cradle bed 4.

[0068] The footboard limiting component 8 is slidably mounted on the footboard support frame 3, and can rise and abut against the footboard of the cradle bed 4 to limit the descent of the footboard of the cradle bed 4.

[0069] The head drive mechanism 9 is installed on the top of the head support frame 2 and is connected to the head of the cradle bed 4 via the transmission rope 15, and is used to drive the head of the cradle bed 4 to rise and fall.

[0070] The tail drive mechanism 10 is installed on the top of the tail support frame 3 and is connected to the tail of the cradle bed 4 via a transmission rope 15, and is used to drive the tail of the cradle bed 4 to lift.

[0071] In this embodiment, the baby cradle bed forms a stable suspension frame through the head support frame 2 and the tail support frame 3. Combined with the head suspension spring 5 and the tail suspension spring 6, the cradle bed 4 is suspended between the support frames, so that the cradle bed 4 can float up and down smoothly under the elastic action of the springs, simulating the action of an adult gently rocking a baby up and down, effectively helping the baby sleep. Meanwhile, the headrest limiting component 7 and the footrest limiting component 8 are slidably mounted on the support frame, and can selectively rise and abut against the head and / or tail of the cradle body 4, thereby realizing multiple usage modes: when both the headrest limiting component 7 and the footrest limiting component 8 rise and abut, the cradle body 4 is fixed in a rigid support state, transforming into a fixed crib, which is convenient for placing and taking out the baby; when the headrest limiting component 7 rises and abuts against the head of the cradle body 4, so that the head is in a supported and fixed state, and at the same time the footrest limiting component 8 descends, so that the tail is suspended by the tail suspension spring 6 and is in an elastic movement state, the tail drive mechanism 10 pulls the tail of the cradle body 4 up and down gently through the transmission rope to realize a single-sided rocking soothing method; when both the headrest limiting component 7 and the footrest limiting component 8 descend, the head drive mechanism 9 and the tail drive mechanism 10 can act synchronously, driving the head and tail of the cradle body 4 to rise and fall simultaneously, realizing an overall lifting and rocking soothing method. Users can flexibly choose between a fixed mode, a single-sided rocking mode, or an overall lifting and rocking mode according to the baby's actual needs and preferences, which significantly improves the flexibility and adaptability of use and effectively reduces the burden on parents to put the baby to sleep.

[0072] Specifically, the baby cradle has a small overall footprint, and the four corners of the bottom of the bed frame 1 are equipped with brakeable casters 14, which can be adjusted in position as needed.

[0073] In some embodiments, the head support frame 2 and the tail support frame 3 may have the same structure; the head limit component 7 and the tail limit component 8 may have the same structure.

[0074] In some embodiments, the head support frame 2 includes a head upright 21, a head upright 22, and a head crossbeam 23; the head upright 21 and the head upright 22 are parallel to each other and their lower ends are hinged to the left and right sides of the top of the head of the bed frame 1; the two ends of the head crossbeam 23 in the length direction are vertically fixed to the upper ends of the head upright 21 and the head upright 22. The tail support frame 3 includes a tail upright 31, a tail upright 32, and a tail crossbeam 33; the tail upright 31 and the tail upright 32 are parallel to each other and their lower ends are hinged to the left and right sides of the top of the tail of the bed frame 1; the two ends of the tail crossbeam 33 in the length direction are vertically fixed to the upper ends of the tail upright 31 and the tail upright 32. The head support frame 2 and the tail support frame 3 are each composed of two parallel, opposing uprights and a top crossbeam, forming a stable portal frame structure. The lower ends of the head upright 21, head upright 22, tail upright 31, and tail upright 32 are hinged to the bed base frame 1, giving the support frame high structural strength and stability in the upright state, reliably supporting the weight of the cradle frame 4 and the infant. The head crossbeam 23 and the tail crossbeam 33 provide clearly defined mounting positions for the drive mechanism and suspension springs, facilitating the assembly and functional implementation of each component.

[0075] In some embodiments, the head support frame 2 and the tail support frame 3 can be flipped and folded around their lower hinge axis and placed on top of the bed frame 1; the head support frame 2 and the tail support frame 3 can also be flipped to an upright state and locked in the upright state by the support positioning mechanism 11.

[0076] The head support frame 2 and tail support frame 3 can be flipped and folded around their lower hinge axes and placed on top of the bed base frame 1, allowing the entire cradle to be folded and stored during transportation or when not in use, significantly reducing its size and facilitating packaging, transportation, and storage. When flipped to the upright position, it is locked by the support positioning mechanism 11 to ensure that the support frame remains stable during rocking and will not fold accidentally. This foldable structure greatly improves the product's portability and space utilization while maintaining its performance, solving the problems of existing hanging basket cribs having a large footprint and being difficult to store.

[0077] In some embodiments, the head support frame 2 and the tail support frame 3 can be locked in an upright state by a hinge shaft self-locking device, and the support is further reinforced by a longitudinally arranged support positioning mechanism 11 to improve stability.

[0078] Specifically, the head support frame 2 and the tail support frame 3 can be connected one-to-one to the head and tail of the bed base frame 1 by a 90-degree self-locking folding hinge.

[0079] In some embodiments, the support positioning mechanism 11 includes a longitudinal support rod 111 and a longitudinal support rod 112. The two ends of the longitudinal support rod 111 can be detachably and vertically connected to the outer peripheral walls of the head support rod 21 and the tail support rod 31, respectively. The two ends of the longitudinal support rod 112 can be detachably and vertically connected to the outer peripheral walls of the head support rod 22 and the tail support rod 32, respectively, so as to position and support the head support frame 2 and the tail support frame 3 in an upright state, thereby further reinforcing them.

[0080] The support and positioning mechanism 11 connects and locks the head support frame 2 and the tail support frame 3 through longitudinal support rod 111 and longitudinal support rod 112. The two longitudinal support rods are arranged horizontally and perpendicular to the head upright 21, head upright 22, tail upright 31, and tail upright 32, forming a stable rigid support structure to ensure that the head support frame 2 and the tail support frame 3 will not undergo relative displacement or folding due to external forces or shaking when in an upright state. At the same time, the longitudinal support rods adopt a detachable connection method, which facilitates quick installation and disassembly, further improving the convenience of folding and storage.

[0081] Specifically, each of the head support rod 21, tail support rod 31, head support rod 22, and tail support rod 32 has a locking member 13 fitted below the head limit component 7 and tail limit component 8; both ends of the longitudinal support rod 111 and both ends of the longitudinal support rod 212 are fixed with locking members 213. The locking members 213 at both ends of the longitudinal support rod 111 can be detachably fitted and snapped onto the locking members 13 fitted on the head support rod 21 and tail support rod 31; the locking members 213 at both ends of the longitudinal support rod 212 can be detachably fitted and snapped onto the locking members 13 fitted on the head support rod 22 and tail support rod 32.

[0082] In some embodiments, the bed frame 1 is a rectangular frame structure and each of its four corners is provided with a limiting hinge seat 12; the lower ends of the head upright 21, the head upright 22, the tail upright 31 and the tail upright 32 are hinged one-to-one on the four limiting hinge seats 12; the limiting hinge seat 12 has a limiting part 121 that restricts the head upright 21, the head upright 22, the tail upright 31 and the tail upright 32 from continuing to rotate when they are rotated to the vertical state.

[0083] The bed frame 1 adopts a rectangular frame structure, with limiting hinge seats 12 at each of its four corners. Each limiting hinge seat 12 has a limiting part 121. When the head upright 21, head upright 22, tail upright 31, and tail upright 32 are flipped to a vertical position, the limiting part 121 abuts against the locking part 2121 on the outer periphery of the hinge joint 212 at the lower end of each upright, restricting further forward flipping and thus precisely locking each upright in a vertical position. This structure not only ensures the stability and safety of the support frame in the vertical state but also, through the abutting action of the limiting part 121, prevents the uprights from excessively flipping due to inertia or external force during swaying, improving the reliability of use.

[0084] Specifically, the lower ends of the head upright 21, head upright 22, tail upright 31, and tail upright 32 are all fixed with hinge joints 212; the hinge joints 212 are hinged to the corresponding limiting hinge seats 12; when the head upright 21, head upright 22, tail upright 31, and tail upright 32 are flipped to the vertical state, the limiting part 121 abuts against the snap-fit ​​part on the outer periphery of the hinge joint 212 at the lower end of the corresponding head upright 21, head upright 22, tail upright 31, and tail upright 32 to limit the flipping.

[0085] Specifically, the top of the limiting hinge seat 12 is provided with a hinge groove; a horizontally arranged hinge shaft is fixed on the opposite side wall inside the hinge groove; the hinge joint 212 is annular and is embedded in the hinge groove and coaxially rotated on the hinge shaft; a snap-fit ​​body is fixed on the outer periphery of the hinge joint 212 to form a snap-fit ​​part. One side of the hinge groove is open to avoid the rotating hinge joint 212, and the other side wall of the hinge groove forms a limiting part 121; when the head upright 21, head upright 22, tail upright 31 and tail upright 32 are flipped to the upright state, the snap-fit ​​body on the outer periphery of the hinge joint 212 at its lower end abuts against the other side wall of the hinge groove to achieve vertical flipping limitation, so as to prevent the head upright 21, head upright 22, tail upright 31 and tail upright 32 from flipping to the outside of the bed frame 1.

[0086] The limiting hinge seat 12 and the support positioning mechanism 11 work together through a "double locking" mechanism: the limiting part 121 of the limiting hinge seat 12 restricts the upright from flipping forward at the hinge point, and the longitudinal support rod of the support positioning mechanism 11 provides lateral connection locking at the overall support frame level. Together, they ensure the accurate positioning and structural rigidity of the head support frame 2 and the tail support frame 3 in the upright state. At the same time, they provide mutual safety redundancy. Even if one fails, the other can still maintain the stability of the support frame, which greatly improves the safety and reliability of the product. In addition, the open hinge slot design of the limiting hinge seat 12 allows the upright to fold inward. Combined with the detachable structure of the support positioning mechanism 11, it realizes convenient switching between folded storage and unfolded use, taking into account both portability and stability.

[0087] In some embodiments, the suspension assembly includes a head suspension spring 5 and a tail suspension spring 6; a suspension member 1 41 and a suspension member 2 42 are respectively fixed on both sides of the top of the head of the cradle bed 4, and a suspension member 3 43 and a suspension member 44 are respectively fixed on both sides of the top of the tail. Suspension component 1 41 and suspension component 2 42 are located between head upright 1 21 and head upright 22, and can slide or roll along the length direction of head upright 1 21 and head upright 22 respectively to fit against their opposite side walls. Suspension component 3 43 and suspension component 44 are located between tail upright 1 31 and tail upright 2 32, and can slide or roll along the length direction of tail upright 1 31 and tail upright 2 32 respectively to fit against their opposite side walls. Both the head suspension spring 5 and the tail suspension spring 6 are in two sets; the two sets of head suspension spring 5 are set along the height direction of the head support frame 2, and their lower ends are hooked to the top of the suspension component 1 41 and the suspension component 2 42 respectively, and their upper ends are hooked to the bottom of the head crossbeam 23. Two sets of tail suspension springs 6 are set along the height direction of the tail support frame 3. Their lower ends are hooked to the top of suspension component three 43 and suspension component four 44 respectively, and their upper ends are hooked to the bottom of the tail crossbeam 33.

[0088] Suspension components 41, 42, 43, and 44 can slide or roll along the length of their respective uprights, conforming to the opposite sidewalls of the uprights. This provides lateral guidance, preventing the cradle frame 4 from directly rubbing against the uprights of the support frame during up-and-down rocking, thus maintaining smooth and quiet movement. Two sets of head and tail suspension springs 5 ​​are hooked to the top of the suspension components and the bottom of the crossbeam, forming four suspension points. This ensures even distribution of suspension force and more stable rocking. Furthermore, the two sets of springs can be selected and configured according to the baby's weight to ensure a similar and adaptable rocking frequency.

[0089] Specifically, each set of head suspension springs 5 ​​and each set of tail suspension springs 6 may include multiple suspension springs; the number, length and stiffness coefficient of the suspension springs can be set and replaced as needed.

[0090] Specifically, the upper end of each set of head suspension springs 5 ​​is hooked onto a mounting plate fixed inside the head crossbeam 23; the upper end of each set of tail suspension springs 6 is hooked onto a mounting plate fixed inside the tail crossbeam 33.

[0091] In some embodiments, a rubber wheel 412 (which can be a silent bearing rubber wheel) is rotatably mounted on the side of the suspension component 41 near the head upright 21, the side of the suspension component 42 near the head upright 22, the side of the suspension component 33 near the tail upright 31, and the side of the suspension component 44 near the tail upright 32. The rubber wheels on the suspension components 41, 42, 43, and 44 can roll along their length on the side walls of the head upright 21, head upright 22, tail upright 31, and tail upright 32 to improve smoothness and quietness.

[0092] In some embodiments, the bottom of suspension component 1 41 and suspension component 2 42 are both provided with a locking groove 411; the bottom of suspension component 3 43 and suspension component 44 are both provided with a locking groove 2. The two ends of the headrest limiting component 7 are slidably sleeved on the headrest 1 21 and the headrest 22 respectively; the headrest limiting component 7 can slide and rise along the length direction of the headrest 1 21 and the headrest 22, and its outer peripheral wall is embedded in the locking groove 1 411 to support and limit the descent of the head of the cradle bed 4. The two ends of the end-of-bed limiting component 8 are slidably sleeved on the end-of-bed upright 31 and the end-of-bed upright 32 respectively. The end-of-bed limiting component 8 can slide upward along the length direction of the end-of-bed upright 31 and the end-of-bed upright 32, and its outer peripheral wall is embedded in the locking groove 2 to support and limit the descent of the end of the cradle bed 4.

[0093] The headboard limiting component 7 and the footboard limiting component 8 are slidably sleeved onto their respective uprights, allowing them to slide upwards along the length of each upright. Their outer perimeters are then embedded in the locking grooves at the bottom of suspension components 41, 42, 43, and 44, forming a rigid support. This mechanism creates a stable mechanical connection between the limiting components and the suspension components, effectively supporting and limiting the descent of the crib body 4, thus achieving a stable fixed crib. When switching to rocking mode, simply lower the limiting components out of their locking grooves; the operation is simple and quick. In the single-sided rocking soothing mode, the outer peripheral wall of the headrest limiting component 7 located on the head support and fixing side is embedded in the corresponding locking groove. While supporting the head of the cradle bed 4 to prevent it from falling, the outer peripheral wall of the headrest limiting component 7 can rotate relative to it in the locking groove around its circumference, forming a rotating pair to adapt to the small angle changes of the head of the bed during the single-sided rocking process, avoiding rigid jamming, thus providing stable support while taking into account the flexibility of rocking.

[0094] In some embodiments, suspension component one 41 and suspension component four 44 have the same structure; suspension component two 42 and suspension component three 43 have the same structure.

[0095] In some embodiments, both the first slot 411 and the second slot are semi-circular slots; the headstock limiting component 7 includes a limiting rod 71 and sliding snap-fit ​​parts 72 fixedly connected to both ends of the limiting rod 71; the tailstock limiting component 8 includes a limiting rod 81 and sliding snap-fit ​​parts 82 fixedly connected to both ends of the limiting rod 81; the sliding snap-fit ​​parts 72 at both ends of the length direction of the limiting rod 71 are slidably sleeved on the headstock 21 and the headstock 22, and can be snapped and positioned on the corresponding headstock 21 and the headstock 22, respectively; the sliding snap-fit ​​parts 82 at both ends of the length direction of the limiting rod 81 are slidably sleeved on the tailstock 31 and the tailstock 32, and can be snapped and positioned on the corresponding tailstock 31 and the tailstock 32, respectively.

[0096] In some embodiments, each of the sliding latches 72 at both ends of the limiting rod 71 is equipped with a telescopically movable positioning pin 721, and each of the head uprights 21 and 22 has a positioning hole 211. The positioning pin 721 on the sliding latch 72 can be movably inserted into the positioning hole 211 of the corresponding head upright 21 and 22 to achieve positioning of the limiting rod 71 on the head upright 21 and 22. Each of the sliding latches 82 at both ends of the limiting rod 81 is equipped with a telescopically movable positioning pin 2, and each of the tail uprights 31 and 32 has a positioning hole 2. The positioning pin 2 on the sliding latch 82 can be movably inserted into the positioning hole 2 of the corresponding tail upright 31 and 32 to achieve positioning of the limiting rod 81 on the tail upright 31 and 32.

[0097] In some embodiments, both ends of the limiting rod 71 in the length direction are slidably fitted with a drive kit 721 that can drive the positioning pin 721 to move in and out of the positioning hole 211.

[0098] The drive assembly includes a spring installed inside the limit rod 71 and a drive sleeve 73 sleeved on the outer periphery of the limit rod 71. One end of the spring is fixed in the inner hole of the limit rod 71, and the other end elastically abuts against one end of the positioning pin 721. When the other end of the positioning pin 721 is aligned with the positioning hole 211, the spring elastically drives the other end of the positioning pin 721 to insert into the positioning hole 211. The drive sleeve 73 is connected to the positioning pin 721. The operator can push the drive sleeve 73 along the length of the limit rod 71, thereby compressing the spring and driving the positioning pin 721 away from the positioning hole 211.

[0099] In some embodiments, both ends of the limiting rod 81 in the length direction are slidably fitted with a driving kit 2 that can drive the positioning pin 2 to move telescopically to engage or disengage from the positioning hole 2.

[0100] The second drive assembly includes a second spring installed inside the second limit rod 81 and a second drive sleeve 83 sleeved on the outer periphery of the second limit rod 81. One end of the second spring is fixed in the inner hole of the second limit rod 81, and the other end elastically abuts against one end of the second positioning pin. When the other end of the second positioning pin is aligned with the second positioning hole, it can elastically drive the other end of the second positioning pin to insert into the second positioning hole. The second drive sleeve 83 is connected to the second positioning pin. The operator can push the second drive sleeve 83 along the length of the second limit rod 81, thereby compressing the second spring and driving the second positioning pin to leave the second positioning hole.

[0101] The headboard limiting component 7 and the footboard limiting component 8 are slidably sleeved on each upright through sliding latching component 1 72 and sliding latching component 2 82, respectively. Precise positioning and reliable locking of the height position are achieved through the cooperation of positioning pin 1 721, positioning pin 2, positioning hole 1 211, and positioning hole 2. Drive sleeve 1 73 and drive sleeve 2 83, under the elastic action of spring 1 and spring 2, allow the positioning pin to automatically insert and lock when it reaches the corresponding positioning hole. The operator only needs to push the drive sleeve to compress the spring and disengage the positioning pin from the positioning hole, thus conveniently sliding and adjusting the position of the limiting component, achieving rapid switching between fixed and rocking modes. When the limiting component rises to the point where its outer peripheral wall is embedded in the locking groove 1 411 and locking groove 2, the semi-circular groove and the outer peripheral wall of the limiting component form a rotational engagement, providing stable support while allowing a certain angle of relative rotation. This adapts to the slight angle changes of the bed head during unilateral rocking, avoiding rigid jamming and balancing safety and flexibility.

[0102] Specifically, there are multiple positioning holes 211 on the head upright 21 and the head upright 22, and multiple positioning holes 2 on the tail upright 31 and the tail upright 32; the multiple positioning holes 211 are spaced apart along the length of the head upright 21 or the head upright 22; the multiple positioning holes 2 are spaced apart along the length of the tail upright 31 and the tail upright 32.

[0103] Specifically, the cradle bed 4 is located between limit rod 1 71 and limit rod 2 81; limit rod 1 71 and limit rod 2 81 can help to block the cradle bed 4 to prevent it from swinging at a large angle along the length of the bed base frame 1.

[0104] In some embodiments, the headboard limiting component 7 and the footboard limiting component 8 have the same structure.

[0105] In some embodiments, the bottom of the cradle bed 4 is provided with a bed depth adjustment section, which can be extended downward along the height direction of the cradle bed 4 to adjust the depth of the cradle bed 4.

[0106] The bottom of the cradle frame 4 is equipped with a depth adjustment section, which can be extended downwards along the height of the cradle frame 4 to adjust its depth. This design allows the cradle to flexibly adjust its depth to accommodate the growth needs of infants at different ages: for smaller infants who cannot yet stand up and move around, the depth adjustment section can be folded down to a shallow position, making it easier for parents to pick them up and care for them; for larger infants who can stand up or move around, the depth adjustment section can be extended to a deeper position, increasing the side wall height and effectively preventing the infant from falling out of the cradle frame 4 when standing, thus improving safety. A single frame structure can cover multiple usage scenarios, reducing the cost for users who purchase multiple cribs.

[0107] In some embodiments, the cradle bed 4 includes a cylindrical bed 45 and a bed zipper 48; the bed depth adjustment part includes a cylindrical flexible connecting part 46 integrally connected to and communicating with the lower end opening of the cylindrical bed 45 and a bed base plate 47 that seals the lower end opening of the cylindrical flexible connecting part 46; the bed zipper 48 includes a first chain belt 481 and a second chain belt 482 that cooperate with each other; the first chain belt 481 is fixed to the outer periphery of the lower end opening of the cylindrical bed 45; the second chain belt 482 is fixed to the outer periphery of the bed base plate 47; When chain belt 1 481 and chain belt 2 482 are pulled together, the cylindrical flexible connecting part 46 is folded and stored inside the bottom of the cylindrical bed 45, and the bed base plate 47 blocks the lower end of the cylindrical bed 45, and the cradle bed 4 is in the first depth state; when chain belt 1 481 and chain belt 2 482 are separated, the cylindrical flexible connecting part 46 unfolds downward to the fully unfolded state, and the bed base plate 47 is suspended from the lower end of the fully unfolded cylindrical flexible connecting part 46, and the cradle bed 4 is in the second depth state.

[0108] The flexible cylindrical connector 46 is made of fabric, and a zipper 48 is sewn around the bottom of the cylindrical bed 45 and the top of the flexible cylindrical connector 46. The depth of the cradle bed 4 can be easily switched by opening and closing the zipper 48. When chain belt 1 481 and chain belt 2 482 are closed, the flexible cylindrical connector 46 is folded and stored inside the bottom of the cylindrical bed 45, and the bed base plate 47 seals the lower opening of the cylindrical bed 45, placing the cradle bed 4 in a shallow position. When the chain belts are separated, the flexible cylindrical connector 46 unfolds downwards to a fully unfolded state, and the bed base plate 47 is suspended below the fully unfolded flexible cylindrical connector 46, placing the cradle bed 4 in a deep position. The bed depth can be easily switched by opening and closing the zipper; the operation is simple, requires no disassembly of any parts, and significantly improves the convenience and flexibility of use.
