Abstract
Description
Technical Field
[0001] This utility model belongs to the field of children's beds, and specifically relates to a multifunctional children's bed. Background Technology
[0002] As a common infant care product, children's beds are widely used in homes, childcare facilities, and medical institutions, mainly to soothe infants, help them fall asleep, or provide gentle passive movement stimulation.
[0003] Most children's beds on the market currently use fixed guardrails, whose main function is to prevent children from falling off the side of the bed during sleep or activity, thus ensuring basic safety. However, this rigid, fixed guardrail reveals significant limitations in actual use. For example, during daily care of infants and toddlers, caregivers frequently need to pick them up, put them down, change diapers, assist with toileting, or engage in parent-child reading. In these situations, the fixed guardrail often becomes a physical obstacle, forcing caregivers to bend over and climb over the guardrail, walk around the foot of the bed, or even temporarily disassemble some guardrail components. Such operations are not only time-consuming and laborious but also reduce care efficiency.
[0004] In addition, traditional children's beds usually do not have posture adjustment functions and cannot meet the needs of diverse usage scenarios. Although there are a few rocking or tilting bed designs, their swinging mechanism and guardrail system are independent of each other, with complex structure, poor stability, and lack of reliable locking mechanism, which poses a risk of tipping over or accidental movement. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a multifunctional children's bed that is simple in structure, stable, easy to operate, and highly safe.

An extension plate is formed on the inner wall of the unlocking block, and the first elastic element, which is arranged vertically, is connected between the extension plate and the inner wall of the lifting rail. Each locking pin is connected to the second elastic element, which is arranged horizontally, between them.
[0019] In the aforementioned multifunctional children's bed, the support platform is detachably connected to the inner wall of the bed body via a support frame. The support frame has through holes, and the bed body has several adjustment holes in the vertical direction. The through holes can be connected to any one of the adjustment holes to adjust the position of the support platform within the receiving cavity.
[0020] In the aforementioned multifunctional children's bed, a replacement railing is detachably connected to one side of the bed frame opposite to the lifting railing. The support platform includes a main platform and side platforms distributed on both sides thereon. A load-bearing block is connected to the bottom of the side platform. The main platform is detachably connected to the load-bearing block and is flush with the surface of the side platform.
[0021] In the aforementioned multifunctional children's bed, the locking mechanism further includes:
[0022] The movable block has an installation groove inside the support frame, and is movably disposed in the installation groove and connected to the stop pin.

[0051] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0052] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0053] like Figures 1 to 11 As shown, this utility model discloses a multifunctional children's bed, which includes a bed frame 1, a lifting rail 2, an unlocking mechanism 3, a support frame 4, and a locking mechanism 5.
[0054] The bed frame 1 has a receiving cavity 10, and a support platform 11 is arranged inside the receiving cavity 10. The lifting rail 2 is movably located on either side of the bed frame 1 and can be switched between an open position and a closed position. The unlocking mechanism 3 is located inside the lifting rail 2 and includes a locking pin 30, which is movably inserted into the bed frame 1 to lock the lifting rail 2 in the open or closed position. The support frame 4 is located at the bottom of the bed frame 1, and a swing block 40 is movably connected to the support frame 4. The swing block 40 can drive the bed frame 1 to move in a horizontal posture relative to the support. The support frame 4 swings back and forth; the locking mechanism 5 is installed inside the support frame 4, and the locking mechanism 5 includes a stop pin 50, which is used to restrict the swing block 40 to a vertical or tilted posture to adjust the relative position between the bed body 1 and the support frame 4; when the lifting rail 2 is in the closed position, the locking pin 30 is inserted into the bed body 1, so that the top wall of the lifting rail 2 is flush with the top wall of the bed body 1; the lifting rail 2 can be switched from the closed position to the open position after the locking pin 30 is unlocked, so that the top wall of the lifting rail 2 is flush with the support platform 11.
[0055] It is worth noting that, such as Figure 1 As shown, the bed frame 1 in this embodiment is composed of a front guardrail, a rear guardrail, and two sets of side rails. The lifting rail 2 in this embodiment is located inside the front guardrail (it should be noted that the installation position of the lifting rail 2 can be adaptively adjusted according to actual needs to accommodate an external adult bed); in the normal state (refer to...) Figure 1 As shown in the diagram, the top of the lifting rail 2 is level with the top wall of the bed frame 1, forming a continuous, stepless guardrail boundary between the lifting rail 2 and the bed frame 1. The locking pin 30, under the force of the unlocking mechanism 3, inserts into the side wall of the bed frame 1 (i.e., the inner wall of the front guardrail), thus firmly locking the lifting rail 2 in the closed position. This effectively prevents children on the support platform 11 from falling, ensuring sleep safety while also improving the overall aesthetics. When the user moves the unlocking mechanism 3 to disengage the locking pin 30 from the bed frame 1 (i.e., the front guardrail), the locking pin 30 releases its constraint on the lifting rail 2, allowing it to move freely along the bed frame 1. Figure 1 Slide vertically downwards until the top wall of the lifting rail 2 is flush with the upper surface of the support platform 11 inside the bed 1, forming a smooth transition plane. This facilitates children getting in and out of bed and parents picking up and putting down infants. It should be noted that when the outer side of the bed 1 is close to an adult bed 1, the flushing of the lifting rail 2 with the support platform 11 means that the support platform 11 is flush with the outer bed 1, thus ensuring that children can easily climb from the crib into the adult bed, balancing protection and ease of access. In addition, in this embodiment, the bed 1 can also adjust its relative position to the support frame 4 using the swing block 40. Similarly, in… Figure 1In the normal operating state shown, the stop pin 50 is inserted into the swing block 40 to ensure that the bed 1 remains firmly locked. When it is necessary to adjust the position and height of the bed 1, the stop pin 50 can be disengaged from the swing block 40 by pulling the locking mechanism 5. As the swing block 40 drives the bed 1 to swing horizontally to the desired position (see reference...), Figure 11 As shown in the diagram, the stop pin 50 extends outside the support frame 4 and abuts against the side wall of the swing block 40. When the user releases the locking mechanism 5, the bed 1 is locked again, effectively limiting the posture of the swing block 40 and preventing accidental shaking or tipping of the bed 1 during use. This structure simplifies the complex operation of the traditional locking mechanism 5, improving user convenience and safety, and is particularly suitable for scenarios such as children's beds that require frequent adjustments to position and height. Therefore, this children's bed integrates safety protection, convenient passage, and multi-posture adjustment functions, significantly improving the flexibility and safety of the children's bed and meeting the care needs of children at different stages.
[0056] The unlocking mechanism 3 also includes: an unlocking block 31, which can be raised and lowered along the height direction of the lifting bar 2; a drive block 32, which is symmetrically arranged on both sides of the unlocking block 31 and moves against the unlocking block 31. When the unlocking block 31 is raised, it can pull the two drive blocks 32 to move towards each other; and a traction rope, with a traction rope connected between each drive block 32 and the locking pin 30.
[0057] like Figures 2 to 5 As shown, when the height of the lifting platform 2 needs to be adjusted, the user pulls the unlocking block 31 upwards along the... Figure 2 The height moves upward (i.e., the unlocking block 31 is lifted). Because the lifting motion of the unlocking block 31 has a horizontal component, it pulls the drive blocks 32 on both sides along... Figure 2 The two sides slide towards each other horizontally. During this process, the movement of the drive block 32 can pull the locking pin 30 away from the bed frame 1 (i.e., the front guardrail) and retract it into the lifting rail 2 via the traction rope (not shown in the figure). This means that the lifting rail 2 can slide and adjust relative to the bed frame 1 (i.e., the front guardrail) in the height direction until the top of the lifting rail 2 is flush with the support platform 11. At this time, the user can release the lifting operation of the unlocking block 31. During the reset process of the unlocking block 31, the locking pin 30 loses the traction force of the traction rope and is inserted back into the bed frame 1, ensuring that the lifting rail 2 is stably locked after the position is adjusted. Therefore, this linkage unlocking mechanism 3 allows the user to operate only a single unlocking block 31 to simultaneously drive the locking pins 30 on both sides to retract, realizing the quick unlocking and position switching of the lifting rail 2. The entire transmission is reliable and easy to operate, avoiding the cumbersome traditional multi-point manual unlocking, improving the convenience and user experience, and is especially suitable for parents to operate with one hand.
[0058] The unlocking block 31 is provided with a push block 310, and a driving slope 310a is formed on the push block 310. The driving block 32 is provided with a fixing block 320, and an unlocking slope 320a is formed on the fixing block 320. The push block 310 moves against the fixing block 320, so that the driving slope 310a moves close to the unlocking slope 320a.
[0059] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the unlocking block 31 is moved along the inclined plane transmission. Figure 2 or Figure 4 The vertical linear motion is efficiently converted into the lateral displacement of the drive block 32 (i.e., the horizontal component force is generated by the inclined plane), which in turn pulls the traction rope to complete the unlocking function of the lock pin 30. The sliding contact between the inclined planes avoids rigid collisions or sudden jumps, making the unlocking process quiet, smooth, and without any jerking, reducing the operating force required for unlocking and improving the user experience. At the same time, the symmetrical inclined plane pair ensures the stable and synchronous movement of the drive blocks 32 on both sides, effectively preventing the lifting railing 2 from tilting or jamming due to uneven force, and improving the stability of long-term use.
[0060] The unlocking mechanism 3 also includes a first elastic element 33 and a second elastic element 34. An extension plate 311 is formed on the inner wall of the unlocking block 31. The extension plate 311 and the inner wall of the lifting rail 2 are connected by a first elastic element 33 arranged in the vertical direction. Each locking pin 30 is connected to the lifting rail 2 by a second elastic element 34 arranged in the horizontal direction.
[0061] like Figure 2 and Figure 4 As shown, along the unlock block 31 Figure 2When the vertical lifting direction is shown, the unlocking block 31 and the driving block 32 achieve force conversion through the two inclined surfaces. At the same time, the first elastic element 33 is subjected to compression and contraction force due to the movement of the extension plate 311, and the second elastic element 34 is compressed and contracted because the traction rope pulls the locking pin 30 into the lifting barrier 2. When the lifting barrier 2 is adjusted to the required position, as the user releases the unlocking force on the unlocking block 31, the elastic reset function of the first elastic element 33 enables the unlocking block 31 to automatically and accurately return to its original position after the user releases the operation. As a result, the unlocking block 31 no longer applies a pulling force to the driving blocks 32 on both sides. Under the elastic reset force of the second elastic element 34, the locking pin 30 is pushed back into the front guardrail, realizing the automatic locking of the lifting barrier 2. With the cooperation of the two elastic elements, this structure ensures the stable locking of the lifting barrier 2 in the closed or open position, improves the safety and automation of use, effectively prevents the lifting barrier 2 from accidentally slipping due to misoperation or forgetting to lock, improves the safety and reliability of use, and also enhances the self-locking reliability of the mechanism. It should be noted that the first / second elastic element 34 in this embodiment can be a compression spring or a return spring 53, etc.
[0062] Preferably, in this embodiment, the unlocking block 31 and the driving block 32 are respectively movably disposed in the horizontal groove and the vertical groove within the lifting rail 2, further restricting the smoothness and stability of their relative movement. Furthermore, this embodiment also has a cover plate 21 detachably connected (with screws or bolts) to the lifting rail 2. A limiting groove 210 is formed within the cover plate 21, and an extension handle 312 passing through the limiting groove 210 is formed on the outer wall of the unlocking block 31. This extension handle 312 facilitates the user's operation of the unlocking block 31 along... Figure 2 The lifting and unlocking operation can be performed, and the limiting groove 210 can be used to restrict the extension handle 312 from sliding along a predetermined trajectory, ensuring the accuracy of the operation. At the same time, the cover 21 can protect the internal structure from dust intrusion, improve the overall protection and aesthetics, and extend the service life.
[0063] The side wall of the lifting rail 2 has a guide block 20, the side wall of the bed 1 has a guide groove 12, and a number of locking holes 120 are provided on the bottom wall of the guide groove 12. The guide block 20 is movably engaged in the guide groove 12 to guide the locking pin 30 to be movably inserted into the locking hole 120.
[0064] like Figure 2 and Figure 3As shown, in this embodiment, the lifting railing 2 and the bed body 1 (i.e., the front guardrail) are movably connected through the cooperation of the guide block 20 and the guide groove 12. After the locking pin 30 unlocks the lifting railing 2, the vertical lifting of the lifting railing 2 relies on the guide block 20 and the guide groove 121 to provide stable guidance, effectively preventing it from tilting, jamming, or shaking during movement, ensuring a smooth lifting process, and improving safety and structural stability. In addition, the multiple locking holes 120 provided on the bottom wall of the guide groove 12 allow the lifting railing 2 to be locked at multiple height positions, thereby adapting to support platforms 11 of different heights or usage scenarios, enhancing structural stability and functional adaptability, and improving the product's versatility and safety.
[0065] The support platform 11 is detachably connected to the inner wall of the bed body 1 via the support frame 110. The support frame 110 has a through hole 110a. The bed body 1 has several adjustment holes 13 in the vertical direction. The through hole 110a can be connected to any one of the adjustment holes 13 to adjust the position of the support platform 11 in the receiving cavity 10.
[0066] like Figure 1 and Figure 6 As shown, in a traditional children's bed, the support platform 11 is the entire bed base. In this embodiment, to adapt to the height of the adult bed 1, the support platform 11 is movably installed inside the children's bed. Specifically, the support platform 11 can be connected to the stepped support frame 110 by screws or bolts, and can be matched with any adjustment hole 13 on the inner wall of the bed 1 by using through holes 110a (the support platform 11 and the bed 1 are detachably connected by screws or bolts). This allows the height of the support platform 11 to be flexibly adjusted according to the child's age, height, or usage needs. This design not only expands the applicable age range of the children's bed, but also improves space utilization efficiency, and is easy to disassemble, transport, and store, with good modularity and adaptability. Therefore, when the height of the external adult bed is inconsistent with the height of the support platform 11, the height of the support platform 11 can be quickly adjusted using the above method. In addition, with the corresponding locking hole 120, it can be ensured that the lifting rail 2 in the open position and the support platform 11 in the adjusted position are on the same horizontal plane, thus providing a safety guarantee for adults to operate and for children to crawl between the support platform 11 and the adult bed.
[0067] The bed frame 1 is detachably connected to a replacement railing 14 on one side relative to the lifting railing 2. The support platform 11 includes a main platform 111 and side platforms 112 distributed on both sides thereon. The bottom of the side platform 112 is connected to a bearing block 112a. The main platform 111 is detachably connected to the bearing block 112a and is flush with the surface of the side platform 112.
[0068] like Figure 7As shown, the support platform 11 in this embodiment adopts a structure combining a main platform 111 and two side platforms 112, and is flush-connected as a whole through a bearing block 112a. This structure not only expands the sleeping or activity area, but also enhances the overall rigidity and load-bearing capacity of the platform. Furthermore, this modular design facilitates transportation, assembly, and subsequent maintenance, and allows for individual component replacement as needed, reducing usage costs. Preferably, the support platform 11 in this embodiment can be horizontal or inclined (to prevent choking on milk). Similarly, the replacement railing 14 in this embodiment can be detachably connected to the bed frame 1 using screws or bolts. It is worth noting that the bottom plate of the bed frame 1 in this embodiment can also adopt the same structural design as the support platform 11. Therefore, in different seasons, usage scenarios, or stages of child development, the user can simultaneously disassemble the replacement railing 14, the main platform 111, the lifting railing 2, and the bottom plate of the children's bed (which has the same structure as the support platform 11; the main platform 111 in the bottom plate can be removed). Figure 7 The middle structure in the exploded view can be disassembled and replaced according to different specifications (by increasing the length to expand the volume of the 10-chamber chamber) or patterns. This greatly enhances the personalization and functionality of the children's bed, extends the product life cycle, and meets diverse childcare needs.
[0069] The locking mechanism 5 further includes: a movable block 51, in which a mounting groove 41 is provided in the support frame 4, the movable block 51 is movably disposed in the mounting groove 41 and connected to the stop pin 50; an unlocking spring 511, one end of the unlocking spring 511 is connected to the movable block 51, and the other end is connected to the mounting groove 41; a stop block 52, the bottom end of the stop block 52 is connected to the bottom wall of the support frame 4 and a vertically placed return spring 53 is connected, the top end of the stop block 52 is connected to the locking pin 520, the outer wall of the movable block 51 is provided with a stop hole 510, and the locking pin 520 is movably inserted into the stop hole 510; and an unlocking button 54, which is located outside the support frame 4 and connected to the stop block 52, the unlocking button 54 is used to drive the stop block 52 to slide relative to the support frame 4, so that the locking pin 520 disengages from the stop hole 510.
[0070] like Figure 8 and Figure 9 As shown, during the unlocking process, the user pulls the unlock button 54, causing the stop block 52 to move along... Figure 8 The vertical downward sliding motion causes the locking pin 520 to disengage from the stop hole 510. At this point, the moving block 51, under the elastic restoring force of the unlocking spring 511, can drive the stop pin 50 along... Figure 8The button 54 moves horizontally to the right, disengaging from the swing block 40. During the unlocking process, the downward movement of the unlock button 54 will inevitably compress the return spring 53, allowing the subsequent moving block 51 to push the stop pin 50 out of the support frame 4. The return spring 53 then drives the stop block 52 to move, inserting the locking pin 520 into the stop hole 510 to complete the automatic locking function. It is worth noting that the unlock button 54 and the stop block 52 have a separate structure (connected by threads or interference fit). The unlock button 54 is exposed on the support frame 4, facilitating pressing by the user. The stop block 52, relying on the return spring 53, can maintain its inserted position into the moving block 51 without external force, ensuring normal and stable locking. This structure is intuitive to operate, provides clear feedback, and the return spring 53 ensures the stability of the locking state, preventing accidental triggering and improving safety for children.
[0071] Preferably, such as Figure 8 and Figure 9 As shown, this embodiment also has a waist-shaped groove 43 inside the support frame 4, and a limiting block 540 is formed on the unlock button 54. During the unlocking action of the unlock button 54 moving down, the sliding of the limiting block 540 in the waist-shaped groove 43 ensures that the unlock button 54 can only slide along the length direction of the waist-shaped groove 43, effectively preventing it from rotating or shifting during use, and ensuring the linearity and reliability of the unlocking action. At the same time, the limiting structure can also limit the unlocking stroke, avoid excessive pressing and damage to internal parts, extend service life, and also prevent the automatic reset locking stroke from being too long and affecting the normal use of the user.
[0072] The swing block 40 is also provided with: a first connecting pin 400 and a second connecting pin 401, which are distributed at the top and bottom of the swing block 40. The first connecting pin 400 is connected to the support frame 4, and the outer wall of the bed body 1 is connected to the support leg 15. The second connecting pin 401 is connected to the support leg 15. A bearing 402 is installed on both the first connecting pin 400 and the second connecting pin 401. The outer ring of the bearing 402 is interference-fitted with the inner wall of the swing block 40. An anti-rotation hole 403 is provided in the middle of the swing block 40. The stop pin 50 can be inserted into the anti-rotation hole 403 when the swing block 40 is in a vertical position.
[0073] like Figure 8 and Figure 11As shown, when the stop pin 50 releases its constraint on the swing block 40, the top of the swing block 40 can rotate relative to the support frame 4 around the axis of the first connecting pin 400. Similarly, since the bottom of the swing block 40 is movably connected to the second connecting pin 401, the swing block 40 can move the fixed support leg 10 while rotating relative to the second connecting pin 401 (i.e., the two are in a movable hinge). This double-hinged linkage structure allows the bed 1 to swing smoothly around the two fulcrums (i.e., the bed 1 always moves in an arc in a horizontal posture). This design not only ensures the smoothness of the swing process but also improves the rigidity and load-bearing capacity of the overall structure. Preferably, this embodiment also forms an extension 405 at the bottom of the swing block 40. This extension 405 can significantly improve the torsional and shear resistance at the second connecting pin 401, avoiding pin wear or breakage caused by unilateral force and extending the service life of the component. It should be noted that in this embodiment, the first connecting pin 400 is inserted into the support frame 4 and can be locked and fixed by a locking pin; the second connecting pin 401 can be connected to the support leg 15 by a threaded connection, and the connection method and principle are the same as those in the prior art, so they will not be described in detail here. In addition, the design of the bearing 402 in this embodiment can significantly reduce the frictional resistance during the swinging process, making the swinging of the bed 1 more light and smooth. At the same time, the bearing 402 structure can also effectively absorb vibration, reduce wear, improve the durability and quietness of the overall structure, and enhance the user experience.
[0074] A guide block 404 is formed on the top side wall of the swing block 40, and an arc-shaped guide groove 42 is formed inside the support frame 4. The guide block 404 is movably disposed in the arc-shaped guide groove 42.
[0075] like Figure 1 , Figure 10 as well as Figure 11 As shown, in the normal state, the vertically oriented swing block 40 is inserted into the anti-rotation hole 403 via the stop pin 50, ensuring that the children's bed will not shift or tilt during use. During the rotation of the swing block 40 relative to the support frame 4, the swing block 40 is always constrained by the trajectory of the arc-shaped guide groove 42, ensuring precise control of its swing angle and preventing excessive swinging or jamming. This guide structure improves the smoothness of the swing motion and the repeatability of positioning accuracy, making it particularly suitable for children's bed applications requiring high precision in posture adjustment. As the guide block 404 slides to either end of the arc-shaped guide groove 42, the stop pin 50 extends outside the support frame 4 and abuts against the outer wall of the swing block 40 (see reference). Figure 11 (as shown in the structure) to ensure that the bed 1 remains absolutely firm and stable after being adjusted.
