Description

Technical Field

[0001] This utility model relates to the technical field of baby rockers, specifically to a baby rocker with convertible modes. Background Technology

[0002] Traditional baby rockers or cribs are typically single-function, designed either as a bed for babies to lie flat or as a cabin for babies to sit or recline. To meet the needs of babies at different stages of development and in different usage scenarios (such as sleeping, feeding, and playing), parents often need to purchase multiple different childcare products. This not only increases the family's financial burden but also occupies valuable living space.

[0003] To integrate functionality, some adjustable baby products have emerged on the market. For example, some cribs allow users to switch between sleeping and sitting positions by manually disassembling and reassembling certain components. However, these products are generally cumbersome to operate and involve multiple steps. Therefore, there is a need for a baby rocker that can stably and reliably switch between sleeping and sitting modes through simple, quick, and safe operation. Utility Model Content

[0004] This utility model proposes a convertible baby rocker. The basket is connected by a railing assembly, a backrest assembly, a seat cushion assembly, and a support assembly. With the backrest assembly and seat cushion assembly linked together, the sleeping bed and seat modes can be switched without disassembly and assembly, reducing the family's economic burden and space occupation.

[0005] A convertible baby rocker designed for this purpose includes a basket having a sleeping mode and a cabin mode; the basket includes a railing assembly, a backrest assembly, a seat cushion assembly and a support assembly; the railing assembly and the support assembly are rotatably connected at their first ends, the backrest assembly and the seat cushion assembly are rotatably connected to the second ends of the support assembly respectively, and the backrest assembly and the seat cushion assembly are linked together. The backrest assembly is equipped with a movable locking block assembly and an unlocking handle. The locking block assembly is located at the mating position between the backrest assembly and the seat cushion assembly and, in the locked state, is used to constrain the rotation of the backrest assembly and the seat cushion assembly relative to the support assembly. The unlocking handle is connected to the locking block assembly. By operating the unlocking handle, the locking block assembly is driven to unlock, the backrest assembly is rotated, and the seat cushion assembly and the backrest assembly rotate in a linked manner relative to the support assembly to switch the mode of the basket. After the mode switch is completed, the unlocking handle and the locking block assembly are reset respectively.

[0006] The seat cushion assembly is provided with an arc-shaped groove, and the two ends of the arc-shaped groove are respectively provided with a cabin locking groove and a bed locking groove. The arc-shaped groove is adapted to the rotation trajectory of the backrest assembly. When the basket body switches to the corresponding mode, one end of the lock block assembly is limited to the corresponding locking slot, the lock block assembly is in a locked state, and the lock block assembly can be driven out of the locking slot by the unlocking handle.

[0007] The seat cushion assembly includes a seat cushion joint, which is rotatably connected to the support assembly, and an arc-shaped groove is provided on the seat cushion joint. The seat cushion assembly also includes a seat cushion tube, a seat cushion plate, and a seat cushion rubber block. One end of the seat cushion tube is inserted into the seat cushion joint and fixedly connected to the seat cushion joint.

[0008] The backrest assembly includes a backrest joint, the support assembly includes a lower joint, the seat joint and the lower joint are respectively installed on the inner and outer sides of the backrest joint, the seat joint and the backrest joint are respectively rotatably connected to the lower joint, and a rotation limiting groove is provided between the backrest joint, the lower joint and the seat joint, and a linkage component installed in the rotation limiting groove, so that the backrest joint and the seat joint form a linkage connection.

[0009] The lower joint has a strip-shaped rotation limiting groove, while the backrest joint and the seat cushion joint have arc-shaped rotation limiting grooves. During the basket mode switching process, when the backrest assembly rotates, the linkage is simultaneously limited to the three limiting grooves. The linkage moves linearly along the strip-shaped rotation limiting groove of the lower joint and moves along the arc-shaped trajectory of the rotation limiting grooves of the backrest joint and the seat cushion joint, so that the backrest assembly and the seat cushion assembly rotate in a linked manner relative to the support assembly. The rotation limiting grooves on the backrest joint and the seat cushion joint are arranged in a figure-eight shape to allow the backrest assembly and the seat cushion assembly to simultaneously retract into the support assembly or simultaneously expand outward from the support assembly.

[0010] The backrest joint is provided with a long groove. The first end of the long groove aligns with the cockpit locking groove or the bed locking groove when the basket mode is switched to the corresponding mode. The second end of the long groove corresponds to the arc-shaped groove during the basket mode switching process.

[0011] The locking block assembly includes a locking pin and a slider. One end of the slider is inserted into the backrest joint, and the locking pin is inserted into the elongated slot and connected to the slider. The other end of the slider is connected to the unlocking handle.

[0012] The backrest assembly also includes a backrest support tube and a backrest plate. The unlocking handle is movably mounted on the backrest support tube, and a transmission component is provided inside the backrest support tube.

Under the preload of the compression spring, the adjusting gear meshes with both toothed grooves simultaneously, thereby achieving locking. An adjusting button is provided on the connecting seat. The adjusting button is inserted and pressed into the connecting seat. By pressing the adjusting button, the adjusting gear is driven to mesh with the toothed groove of the fence joint, and the adjusting gear disengages from the toothed groove of the connecting seat, so that the fence assembly rotates between the connecting seat and the upper joint.

[0015] The beneficial technical effects of this utility model are as follows: The above structure solves the problems of limited functionality and cumbersome switching in traditional baby products. The basket is connected by rotating components—the railing assembly, backrest assembly, seat cushion assembly, and support assembly—and the coordinated design of the backrest and seat cushion assemblies allows for easy switching between sleeping and sitting modes without disassembly or reassembly, reducing the financial burden on families and saving space. The unlocking handle drives the locking assembly to unlock, making operation simple and quick, and can be completed by a single person. After the mode switch is completed, the unlocking handle and locking assembly reset, restraining the rotation of the backrest and seat cushion assemblies relative to the support assembly, preventing loosening after mode switching, and ensuring the baby's safety. Compared to manually disassembled products, this significantly improves switching efficiency and reliability. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] See Figures 1-13 A convertible baby rocker includes a basket having a sleeping mode and a cabin mode; the basket includes a railing assembly 1, a backrest assembly 2, a seat cushion assembly 3 and a support assembly 4; the railing assembly 1 and the support assembly 4 are rotatably connected at their first ends, the backrest assembly 2 and the seat cushion assembly 3 are rotatably connected to the second ends of the support assembly 4 respectively, and the backrest assembly 2 and the seat cushion assembly 3 are linked together. The backrest assembly 2 is provided with a movable locking block assembly 5 and an unlocking handle 6. The locking block assembly 5 is located at the mating position between the backrest assembly 2 and the seat cushion assembly 3 and is used to constrain the rotation of the backrest assembly 2 and the seat cushion assembly 3 relative to the support assembly 4 in the locked state. The unlocking handle 6 is connected to the locking block assembly 5. By operating the unlocking handle 6, the locking block assembly 5 is driven to unlock, the backrest assembly 2 is rotated, and the seat cushion assembly 3 and the backrest assembly 2 rotate in a linked manner relative to the support assembly 4 to switch the mode of the basket. After the mode switch is completed, the unlocking handle 6 and the locking block assembly 5 are reset respectively.

[0033] The connection method between the playpen assembly, backrest assembly, seat cushion assembly, and support assembly, along with the locking block assembly and unlocking handle on the backrest assembly, solves the problems of limited functionality and cumbersome switching in traditional baby products. The basket body is connected by the rotation of the playpen assembly 1, backrest assembly 2, seat cushion assembly 3, and support assembly 4. The coordinated design of backrest assembly 2 and seat cushion assembly 3 allows for easy switching between sleeping and sitting modes without disassembly and reassembly, reducing the financial burden on families and saving space. The unlocking handle 6 drives the locking block assembly 5 to unlock, making operation simple and quick, and can be completed by a single person. After the mode switch is completed, the unlocking handle 6 and locking block assembly 5 reset, restraining the rotation of backrest assembly 2 and seat cushion assembly 3 relative to support assembly 4, preventing loosening after mode switching, and ensuring the baby's safety. Compared to manually disassembled products, this significantly improves switching efficiency and reliability. The seat cushion assembly 3 is provided with an arc-shaped groove 302, and the two ends of the arc-shaped groove 302 are respectively provided with a cabin locking groove 303 and a bed locking groove 304. The arc-shaped groove 302 is adapted to the rotation trajectory of the backrest assembly 2. When the basket body switches to the corresponding mode, one end of the locking block assembly 5 is limited to the corresponding locking slot, the locking block assembly 5 is in a locked state, and the locking block assembly 5 can be driven out of the locking slot by the unlocking handle 6.

[0034] The arc-shaped groove 302 adapts to the rotation trajectory of the backrest assembly 2, ensuring smooth movement of components without any jamming during mode switching. The cockpit locking groove 303 and the bed locking groove 304 correspond to the two modes respectively. The locking block assembly 5 is limited in the corresponding mode, accurately locking the basket state and avoiding the structural instability problem of traditional products after conversion. When unlocking, the locking block assembly 5 can disengage from the locking groove, requiring fewer operation steps and no complicated adjustments, further simplifying the conversion process. At the same time, the limiting function of the locking groove enhances the safety of product use.

[0035] The cushion assembly 3 includes a cushion joint 301, which is rotatably connected to the support assembly 4, and an arc-shaped groove 302 is provided on the cushion joint 301. The seat cushion assembly 3 also includes a seat cushion bend 305, a seat cushion plate 306, and a seat cushion rubber block 307. One end of the seat cushion bend 305 is inserted into the seat cushion joint 301 and fixedly connected to the seat cushion joint 301. The seat cushion plate 306 and the seat cushion rubber block 307 are respectively fixed on the upper and lower outer surfaces of the seat cushion bend 305.

[0036] The seat joint 301 not only enables rotational connection with the support assembly 4, but also provides a stable mounting carrier for the arc-shaped groove 302. The seat bend 305 is fixedly connected to the seat joint 301, enhancing the overall structural strength of the seat assembly 3 and preventing deformation over long-term use; the seat plate 306 provides a flat support surface for the baby. The seat cushion plate 306 and the seat cushion rubber block 307 are respectively fixed to the upper and lower outer surfaces of the seat cushion tube 305 by screws or welding. A seat cushion joint 301 is inserted into each end of the seat cushion tube 305, and the end of the seat cushion tube 305 is fixed by screws after being inserted into the seat cushion joint 301.

[0037] The backrest assembly 2 includes a backrest joint 201, and the support assembly 4 includes a lower joint 401. The seat joint 301 and the lower joint 401 are respectively installed on the inner and outer sides of the backrest joint 201. The seat joint 301 and the backrest joint 201 are rotatably connected to the lower joint 401. A rotation limiting groove 8 is provided between the backrest joint 201, the lower joint 401 and the seat joint 301, and a linkage member 7 is installed in the rotation limiting groove 8 so that the backrest joint 201 and the seat joint 301 form a linkage connection.

[0038] The inner and outer mounting methods of the backrest joint 201, lower joint 401, and seat cushion joint 301 result in a compact component layout, saving overall product space. The rotation limit groove 8 and linkage component 7 between the three components work together to precisely control the linkage relationship between the backrest assembly 2 and the seat cushion assembly 3.

[0039] The rotation limiting groove 8 of the lower joint 401 is strip-shaped, and the rotation limiting grooves 8 of the backrest joint 201 and the seat cushion joint 301 are arc-shaped. During the basket mode switching process, when the backrest assembly 2 rotates, the linkage 7 is simultaneously limited to the three limiting grooves 8. The linkage 7 moves linearly along the strip-shaped rotation limiting groove 8 of the lower joint 401, and moves along the arc-shaped trajectory of the rotation limiting grooves 8 of the backrest joint 201 and the seat cushion joint 301, so that the backrest assembly 2 and the seat cushion assembly 3 rotate in a linked manner relative to the support assembly 4.

[0040] The rotation limiting grooves 8 on the backrest joint 201 and the seat cushion joint 301 are arranged in a figure-eight shape to allow the backrest assembly 2 and the seat cushion assembly 3 to simultaneously retract into the support assembly 4 or simultaneously expand outward from the support assembly 4.

[0041] The backrest joint 201 is provided with a long groove 202. The first end of the long groove 202 is aligned with the cockpit locking groove 303 or the bed locking groove 304 when the basket mode is switched to the corresponding mode. The second end of the long groove 202 corresponds to the arc groove 302 during the basket mode switching process.

[0042] The locking block assembly 5 includes a locking pin 501 and a slider 502. One end of the slider 502 is inserted into the backrest joint 201, and the locking pin 501 is inserted into the elongated groove 202 and connected to the slider 502. The other end of the slider 502 is connected to the unlocking handle 6.

[0043] The backrest assembly 2 also includes a backrest support tube 203 and a backrest plate 204. The unlocking handle 6 is movably disposed on the backrest support tube 203, and a transmission component 9 is provided inside the backrest support tube 203. One end of the transmission component 9 is connected to the slider 502, and the other end of the transmission component 9 is connected to the unlocking handle 6. One end of the slider 502 extends out of the backrest support tube 203, and the other end of the slider 502 is inserted into the backrest support tube 203. The backrest support tube 203 drives the slider 502 to be inserted into the backrest joint 201. Fasteners are provided between the backrest support tube 203 and the backrest joint 201. The backrest support bend 203 is provided with a spring 10. One end of the spring 10 abuts against the slider 502, and the other end of the spring 10 abuts against the fastener, so that the slider 502 is elastically and movably mounted on the backrest assembly 2. The transmission component 9 is a pull rope or steel wire; the backrest plate 204 is fixed on the backrest support bend 203.

[0044] The elongated groove 202 provides a precise path for the movement of the locking block assembly 5. When the first end aligns with the corresponding locking groove, it guides the locking block assembly 5 to accurately insert into the locking groove, ensuring reliable locking after mode switching and preventing locking failure due to lock block misalignment. The second end corresponds to the arc-shaped groove 302, allowing the locking block assembly 5 to move smoothly along the trajectory of the arc-shaped groove 302 during mode switching. The locking pin 501 is inserted into the elongated slot 202, which can precisely match the elongated slot 202 and the locking slot to achieve locking. The slider 502 acts as a transmission carrier, connecting the locking pin 501 and the unlocking handle 6, so that the operating force of the unlocking handle 6 can be directly transmitted to the locking pin 501. The backrest support bend 203 enhances the structural strength of the backrest assembly 2 and provides installation space for the unlocking mechanism, achieving component integration and optimizing product layout. The transmission component 9 uses a pull rope or steel wire, flexibly adapting to the internal space of the backrest support bend 203, ensuring reliable transmission without occupying extra space. After mode switching is complete, the spring 10 pushes the slider 502 to automatically reset, and the reset of the slider 502 drives the unlocking handle 6 to reset, requiring no additional operation. The backrest panel 204 provides a stable support surface for the baby, ensuring comfortable sitting and balancing structural integrity and user experience.

[0045] The backrest support bend 203 is provided with a mounting box 11, which is fixed to the backrest support bend 203. The unlocking handle 6 is press-fitted into the mounting box 11. The mounting box 11 is provided with a transverse groove 1101, and the unlocking handle 6 is provided with an oblique groove 601. The mounting box 11 is provided with a transmission pin 12, which is inserted into the oblique groove 601 and the transverse groove 1101 and connected to the transmission component 9. When the unlocking handle 6 is pressed, the transmission pin 12 moves in a limited position in the oblique groove 601 and the transverse groove 1101, thereby driving the transmission component 9, the movable slider 502 and the locking pin 501 to move.

[0046] The support assembly 4 also includes a support rod 402 and an upper joint 403, with the upper part of the support rod 402 inserted into the upper joint 403 and the lower part of the support rod 402 inserted into the lower joint 401. The fence assembly 1 includes a fence joint 101 and fence bends 102 fixed to both ends of the fence joint 101. An upper joint 403 is located inside the fence joint 101, and the fence joint 101 is rotatably connected to the upper joint 403. A connecting seat 13 is provided on the outer side of the fence joint 101, and the connecting seat 13 is rotatably connected to the fence joint 101. An adjusting gear 14 and a compression spring 15 are provided between the connecting seat 13 and the fence joint 101. Both the connecting seat 13 and the fence joint 101 have toothed grooves 16 that mesh with the adjusting gear 14. The compression spring 15... One end of the spring 15 is abutted against the adjusting gear 14, and the other end of the compression spring 15 is connected to the fence joint 101. Under the preload of the compression spring 15, the adjusting gear 14 simultaneously engages with the two tooth grooves, thereby achieving locking. The connecting seat 13 is provided with an adjusting button 17, which is inserted and pressed into the connecting seat 13. By pressing the adjusting button 17, the adjusting gear 14 is driven to engage with the tooth groove 16 of the fence joint 101, and the adjusting gear 14 disengages from the tooth groove 16 of the connecting seat 13, so that the fence assembly 1 rotates between the connecting seat 13 and the upper joint 403.

[0047] The mounting box 11 protects the internal unlocking components, preventing dust intrusion or accidental contact that could lead to structural failure and extend the component's lifespan. The push-button unlocking handle 6 is ergonomically designed, allowing parents to operate it with one hand, solving the problem of traditional products requiring two hands for unlocking and improving ease of use. The inclined groove 601 and the transverse groove 1101 work together to precisely convert the pressing action into the transverse movement of the transmission pin 12, which in turn drives the transmission component 9, the slider 502, and the locking pin 501. This high transmission efficiency and minimal wasted force ensure smooth unlocking operation and further simplify the mode switching process. The support rod 402 connects the upper joint 403 and the lower joint 401, enhancing the overall strength of the support assembly 4 and ensuring that the product can stably support the baby's weight, avoiding the instability problem of traditional products. The fence assembly 1 is rotatably connected to the upper joint 403 via the fence joint 101. Combined with the adjustment structure of the connecting seat 13, the fence angle can be flexibly adjusted. The adjusting gear 14 works with the compression spring 15 to ensure a secure lock. Pressing the adjustment button 17 unlocks the rotation, simplifying operation and improving the convenience and reliability of fence adjustment. I. The process of switching between bed mode and cabin mode is as follows: Unlocking operation: Press the unlocking handle 6 inside the mounting box 11 on the backrest support bend tube 203. The inclined groove 601 of the unlocking handle 6 drives the transmission pin 12 to move in the transverse groove 1101 of the mounting box 11. The transmission pin 12 pulls the transmission component 9 (pull rope or steel wire). The transmission component 9 drives the slider 502 to compress the spring 10 inside the backrest support bend tube 203. The slider 502 drives the locking pin 501 to move along the long groove 202 of the backrest joint 201, disengaging from the corresponding cabin locking groove 303 or bed locking groove 304 at both ends of the arc groove 302 of the seat cushion assembly 3, thus completing the unlocking. Linkage rotation switching mode: Rotate the backrest assembly 2, and the backrest joint 201 rotates around the lower joint 401 of the support assembly 4; at this time, the linkage 7 moves simultaneously in the arc-shaped rotation limiting groove 8 of the backrest joint 201, the strip-shaped rotation limiting groove 8 of the lower joint 401, and the reverse arc-shaped rotation limiting groove 8 of the seat cushion joint 301. The linkage 7 moves linearly along the strip-shaped groove of the lower joint 401, driving the seat cushion assembly 3 to rotate synchronously around the lower joint 401, so that the backrest assembly 2 and the seat cushion assembly 3 can be simultaneously folded inward to the support assembly 4 (bed to seat) or unfolded outward (seat to bed). The cockpit locking groove 303 is a groove with a certain depth. After the locking block assembly 5 (locking pin 501) is inserted into the groove, it cannot slide out of the groove at will without unlocking. Moreover, when the baby leans against the tilted backrest assembly 2, the locking pin 501 abuts against the inside of the groove to ensure that the backrest assembly 2 will not flip down.

[0048] The first end of the elongated groove 202 on the backrest joint 201 aligns with the cockpit locking groove 303 or the bed locking groove 304 in the corresponding mode, providing guidance for the locking action of the locking block assembly 5 and ensuring that the locking block assembly 5 (locking pin 501) can be accurately inserted into the corresponding cockpit locking groove 303 or bed locking groove 304. The second end of the elongated groove 202 corresponds to the arc-shaped groove 302 during mode switching, providing auxiliary guidance for the movement of the locking block assembly 5 (locking pin 501), so that the locking block assembly 5 (locking pin 501) always stays within the preset trajectory when moving with the arc-shaped groove 302, preventing the locking block assembly 5 (locking pin 501) from deviating during movement.

[0049] The lower joint 401 and the seat cushion joint 301 are respectively provided with shaft holes between the backrest joint 201 and the three shaft holes, and the connecting shaft is inserted into the shaft holes to realize the shaft hole connection.

[0050] The bed locking groove 304 is horizontal. When the locking pin 501 is engaged in the bed locking groove 304, the backrest assembly 2 cannot be flipped up or down.

[0051] The backrest support tube 203 of the backrest assembly 2 provides an installation position for the unlocking handle 6, and the internal transmission component 9 connects the slider 502 and the unlocking handle 6, which can efficiently transmit the operating force of the unlocking handle 6. The backrest support tube 203 and the backrest joint 201 are connected by fasteners (screws). One end of the spring 10 inside the backrest support tube 203 abuts against the slider 502 and the other end abuts against the fastener (screw), which can automatically push the slider 502 to reset after the unlocking handle 6 is released; and when the slider 502 resets, it pulls the transmission component 9 to reset the unlocking handle 6. The lock handle 6 can also be equipped with a reset spring to reset.

[0052] Locking Reset: When the basket is switched to the target mode (bed or cabin), the spring 10 resets and pushes the slider 502. The slider 502 drives the locking pin 501 to move along the long groove 201 and insert into the locking groove of the corresponding mode (bed locking groove 304 or cabin locking groove 303). The locking block assembly 5 resets and locks, and the mode switching is completed.

[0053] The backrest support bend 203 can be divided into upper and lower parts, or the backrest support bend 203 can be composed of multiple connecting pipes, which facilitates assembly.

[0054] II. The angle adjustment process for fence component 1 is as follows: Pressing the adjustment button 17 on the connecting seat 13 pushes the adjustment gear 14 to compress the compression spring 15 inside the fence joint 101, causing the adjustment gear 14 to disengage from the tooth groove 16 of the connecting seat 13 and engage only with the tooth groove 16 of the fence joint 101. At this time, rotate the fence assembly 1, and the fence joint 101 rotates around the upper joint 403 of the support assembly 4. After adjusting to the required angle, release the adjustment button 17, and the compression spring 15 resets and pushes the adjustment gear 14. When the adjustment button 17 resets, the adjustment gear 14 returns to abutting against the inner side of the connecting seat 13. Since the adjustment gear 14 does not engage with the tooth groove 16 of the connecting seat 13 after resetting, rotate the connecting seat 13 alone. When the tooth groove 16 aligns with the tooth of the adjustment gear 14, the tooth of the adjustment gear 14 engages with the tooth groove 16 of the connecting seat 13 under the action of the compression spring 15.

[0055] The fence joint 101 is equipped with a rotating shaft, the adjusting gear 14 is sleeved on the outside of the rotating shaft, and the connecting seat 13 is equipped with a connecting shaft inserted into the rotating shaft.
