Description
A multifunctional baby crib Technical Field
[0001] This utility model belongs to the field of baby bed technology, specifically relating to a multifunctional baby bed. Background Technology
[0002] To provide a safer and more comfortable sleeping environment for babies, most families with infants now have cribs.
[0003] Most baby cribs are fixed structures, meaning they are placed on the ground and do not have a gentle rocking function. When a baby is uncomfortable (such as hungry) and cries, the crib cannot be rocked, so it cannot temporarily soothe the baby. Caregivers have to prepare formula while holding the baby, which is very inconvenient.
[0004] Furthermore, when a baby wets their diaper, the crib lacks a suitable platform for smoothing it out, requiring caregivers to spend time searching for a suitable spot, which is very inconvenient. Similarly, when feeding the baby solid foods, the lack of a platform means there's nowhere to place the baby's bowl and utensils. If the baby spits up, caregivers cannot immediately put down the bowl and utensils to attend to the baby; they must find another platform to place the bowl and utensils before addressing the spit-up, which is also very inconvenient. Summary of the Invention
[0005] In order to solve the problems in the prior art, this utility model proposes a multifunctional baby bed.
[0006] To achieve the above objectives, the present invention proposes the following technical solution:
[0007] A multifunctional crib includes a crib seat with a downward-facing groove on the upper surface of the crib seat; a rocker frame is provided in the groove, and the upper end of the rocker frame is open.
[0008] A first notch is provided on one side of the rocker frame; a flap is provided at the first notch, the lower end of which is rotatably connected to the rocker frame. The pivot of the flap passes through the mounting hole at the first notch of the rocker frame, and the flap can rotate relative to the rocker frame around its pivot axis. When the flap rotates to a vertical angle, it can cover the first notch and form a complete rocker frame. When the flap rotates to a horizontal angle, it can serve as a placement platform. A second notch is provided on the side of the bed near the flap to avoid interfering with the rotation of the flap. A stop block is fixedly connected to the flap. When the flap rotates to a horizontal angle, the stop block abuts against the corresponding surface of the rocker frame. A buckle assembly is provided on both the flap and the rocker frame to prevent the flap from falling due to gravity when the flap is vertical.
[0009] The device flips up to a horizontal position, creating a platform where caregivers can place items needed for infant care, such as changes of clothes, diapers, bowls, and bottles. This allows caregivers to place all necessary items on the platform at once, eliminating the need for repeated trips and freeing up their hands to attend to the infant's emotional needs.
[0010] Furthermore, the latching assembly includes:
[0011] The first retaining ring is fixed to the flap plate. When the flap plate is at a vertical angle, the first retaining ring is located on the upper surface of the flap plate.
[0012] The hook spring is connected at one end to the first retaining ring via a ring buckle connection.
[0013] The second retaining ring is fixed to the upper surface of the rocker frame, and the other end of the hook spring is hooked onto the second retaining ring.
[0014] The latching mechanism prevents the flap from falling freely when placed at a vertical angle. After unlocking, gravity and a stop block automatically create a horizontal platform, balancing safety and convenience.
[0015] Furthermore, the bottom of the rocker frame is provided with two sets of rocking components for moving the rocker frame. The rocking components include:
[0016] The lower base is fixedly connected to the upper surface of the groove;
[0017] Two first support shafts are fixedly connected to the lower base 41; the two first support shafts are arranged side by side along the Y direction, and the axes of the two first support shafts are parallel to the X direction; in the top view, the X direction is perpendicular to the Y direction.
[0018] Two sets of connecting rods are arranged side by side along the Y direction. Each set contains two connecting rods arranged side by side along the X direction. In one set of connecting rods, the lower ends of the two connecting rods are rotatably connected to the two ends of one of the first support shafts.
[0019] The upper base is fixed to the lower surface of the rocker frame;
[0020] Two second support shafts are fixedly connected to the upper base. The two second support shafts are arranged side by side along the Y direction, and the axes of the two second support shafts are parallel to the X direction. In a set of connecting rods, the upper ends of the two connecting rods are rotatably connected to the two ends of the corresponding second support shafts. From a perspective parallel to the X direction, if the points where the two first support shafts and the two second support shafts are located are A, B, C and D respectively, then quadrilateral ABCD is a parallelogram. It also includes a drive assembly for moving the rocker frame.
[0021] It can provide a certain displacement to the rocking frame, based on the principle of a parallelogram structure. This displacement occurs not only horizontally but also vertically. Therefore, it can somewhat distract the baby and reduce crying. Moreover, the logic control of the servo motor makes the displacement speed relatively slow. Since the baby's brain is not fully developed, excessive external stimulation may affect its development. Therefore, slight, short-term shaking will not affect the baby's brain and can also reduce the baby's crying, preventing caregivers from becoming impatient and making related mistakes.
[0022] Furthermore, the driving component includes:
[0023] Both supports are fixedly connected to the upper surface of the lower base;
[0024] The ball screw nut has its two ends rotatably connected to corresponding supports, and the screw axis is parallel to the Y direction; the nut is movably locked on the upper surface of the lower base, and the upper surface of the lower base has a sliding groove for the nut to slide, and the nut can only slide relative to the sliding groove in the Y direction.
[0025] The drive rod is hinged to a nut at one end and rotatably connected to one of the second support shafts at the other end.
[0026] The servo motor, mounted on the upper surface of the lower base, is used to rotate the lead screw.
[0027] Furthermore, the side of the rocker frame is provided with an oblong hole, the width of which along the Y direction is less than 10cm.
[0028] The waist-shaped opening provides light and ventilation for the baby, improving the comfort of the rocker. Since a baby's head diameter is generally greater than 10cm, designing the waist-shaped opening to be narrower along the Y-axis helps prevent the baby's head from getting stuck.
[0029] Furthermore, casters are installed at all four corners of the bottom of the bed seat.
[0030] The casters facilitate overall movement, especially at night when the crib needs to be moved to the caregiver's side.
[0031] The beneficial effects that can be achieved by adopting the above technologies are:
[0032] When the flip-up panel is turned to a horizontal position, it forms a platform that can be used to place items needed to care for the baby, reducing the time caregivers spend searching for other platforms and making it easier for caregivers to respond promptly to the baby's cries.
[0033] The design incorporates a rocking component that provides a slight lateral movement to the baby in the rocking frame during the short period when the caregiver is searching for the desired object. This helps to distract the baby and reduce crying. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0042] As shown in Figures 1 and 2, a multifunctional baby crib includes the following structure:
[0043] In this embodiment, the bed base 1 is rectangular in shape, with its upper surface cut downwards to form a groove. At each of the four corners of the bottom of the bed base 1, casters 2 with self-locking structures are installed. These casters 2 are existing finished products, fixed to the bottom of the bed base 1 by bolts, facilitating overall movement and securing the position via the self-locking function.
[0044] The rocking frame 3 is placed in the groove of the bed base 1. It is a rectangular frame with an open top. The other sides of the rocking frame 3 are plates, but several waist-shaped holes are opened on each of the four sides of the rocking frame 3 to ensure the light and air transmission of the rocking frame 3. At the same time, the width of the waist-shaped holes along the Y direction is less than 10cm to prevent the baby's head from getting stuck. In the top view, it is arranged with one side along the X direction and the adjacent side along the Y direction. There are two sets of rocking components 4 arranged side by side along the X direction at the bottom, which also serve to support the rocking frame 3 and connect to the bed base 1. By energizing the two sets of components simultaneously, the rocking frame can produce a slight reciprocating displacement with a certain speed and amplitude, soothing the baby.
[0045] As shown in Figures 3 and 4, the shaking component 4 includes:
[0046] The lower base 41 is fixedly connected to the upper surface of the groove;
[0047] Two first support shafts 42 are fixedly connected to the lower base 41. The two first support shafts 42 are arranged side by side along the Y direction, and the axes of the two first support shafts 42 are parallel to the X direction.
[0048] Two sets of connecting rods 43 are arranged side by side along the Y direction, and each set includes two connecting rods 43 arranged side by side along the X direction. The two sets of connecting rods 43 are respectively connected to two first support shafts 42. Specifically, in one set of connecting rods 43, the lower ends of the two connecting rods 43 are respectively sleeved on both ends of one of the first support shafts 42 and are rotatably connected to the first support shaft 42 through bearings.
[0049] The upper base 44 is fixedly connected to the lower surface of the rocker frame 3;
[0050] Two second support shafts 45 are fixedly connected to the upper base 44. The two second support shafts 45 are arranged side-by-side along the Y-direction, and their axes are parallel to the X-direction. The upper ends of the aforementioned two sets of connecting rods 43 are respectively sleeved on both ends of the two second support shafts 45 and rotatably connected to them via bearings. Viewed from a perspective parallel to the X-direction, if the points where the two first support shafts 42 are located are A and B, and the points where the two second support shafts 45 are located are C and D, then quadrilateral ABCD is a parallelogram. The connecting rods, first support shafts, and second support shafts 45 in this design are all made of high-strength aluminum alloy to ensure the strength requirements for support during the movement of the rocker frame 3, while also possessing high fatigue strength, with a cycle life exceeding 10^6, meeting practical requirements.
[0051] It also includes a drive component for causing the rocker arm 3 to move.
[0052] Two supports 46 are fixedly connected to the upper surface of the lower base 41; they are arranged side by side along the Y direction;
[0053] The ball screw nut has its two ends of the screw 47 rotatably connected to the corresponding supports 46, and the axis of the screw 47 is parallel to the Y direction.
[0054] The drive rod 48 has one end hinged to the nut 49 of the ball screw nut 47 via a shaft, and the other end rotatably connected to one of the second support shafts 45 via a bearing. The axes of both ends of the drive rod 48 are parallel to the X direction. The nut 49 is movably mounted on the lower base 41, which has a dovetail-shaped groove for the nut 49 to slide. The nut 49 can only slide relative to the groove in the Y direction.
[0055] The servo motor (not shown) is fixedly mounted on the lower base 41 at the non-rotating shaft end. It is connected to one end of the lead screw 47 of the ball screw nut via a coupling, and is used to rotate the lead screw 47.
[0056] Since the two sets of rocking components 4 are connected in the same circuit, and the button controlling the activation of the two sets of rocking components 4 is located in the main circuit of this circuit, when the button is pressed (a button that does not automatically pop up), the two servos of the two sets of rocking components 4 are simultaneously energized and act synchronously, ensuring that the rocker frame 3 can always "sway" in the Y direction by relying on the formed parallelogram ABCD. The meaning of swaying is: based on the deformation of the parallelogram structure, the rocker frame moves back and forth in the horizontal direction, while also having a change in height. During the "swaying" process, since the rocker frame 3 always remains horizontal and will not tilt, it will not cause the baby to slide sideways in the rocker frame 3. Controlled by the logic of the controller that controls the steering of the servos in the circuit, the two servos (at a speed of 60 rpm) rotate clockwise 5 times within 5 seconds and then stop. After stopping for 1 second, the two servos rotate counterclockwise 5 times within 5 seconds and then stop again. After stopping for another 1 second, they rotate clockwise 5 times within 5 seconds and then stop again, repeating this process to keep the rocker arm 3 in motion. Each movement results in a single translation of the rocker arm 3, with a translation range of ±200mm. To stop, simply press the button again, allowing it to spring back and disconnect the circuit. In practice, sensors are added to the two servos to limit their rotation speed and ensure synchronization; this is a conventional method and will not be elaborated upon in this solution.
[0057] As shown in Figures 1 and 2, the crib also includes:
[0058] The first notch 5 is formed on one side of the rocker frame 3. In this embodiment, the first notch 5 is located on one side of the rocker frame 3 in the Y direction.
[0059] The flap 6 (see Figure 5) is rotatably connected to the rocker frame 3 at its lower end. The pivot of the flap 6 passes through a mounting hole at the first notch 5 of the rocker frame 3. The diameter of this hole is slightly larger than the outer diameter of the pivot, allowing the flap to rotate freely around the X-axis. Since the mounting hole does not restrict the movement of the flap 6, the flap 6 can rotate relative to the rocker frame 3 around its pivot axis, which is along the X-direction. When the flap 6 rotates to a vertical angle, it can cover the first notch 5, forming a complete rocker frame 3. When the flap 6 rotates to a horizontal angle, it can serve as a platform for placing bowls or diapers.
[0060] The second notch 7 is located on the side of the bed seat 1 near the flip plate 6, and is used to prevent the flip plate 6 from being interfered with by the bed seat 1 when it is turned to a horizontal angle.
[0061] The abutment block 8 is fixed to the flap 6. When the flap 6 is rotated to a horizontal angle, the abutment block 8 just abuts against the surface of the rocker frame 3 in the Y direction (as shown in Figure 5).
[0062] Both the flap 6 and the remote frame 3 are equipped with a latching assembly to keep the flap 6 at a vertical angle and prevent it from falling due to gravity. The latching assembly includes:
[0063] The first retaining ring 10 is fixed to the flap 6. When the flap 6 is at a vertical angle, the first retaining ring 10 is located on the upper surface of the flap 6.
[0064] The hook spring 9 has hooks at both ends. One end is deformed into a ring shape by a tool. This end is connected to the first retaining ring 10 by a ring buckle and cannot be detached from the first retaining ring 10.
[0065] The second retaining ring 11 is fixed to the upper surface of the rocker frame 3. The hook-shaped structure at the other end of the hook spring 9 can hook onto the second retaining ring 11. When the flip plate 6 is vertical, the two ends of the hook spring 9 hook onto the two retaining rings respectively, providing resistance to prevent the flip plate 6 from flipping over on its own. When the platform is needed, the end of the hook spring located on the second retaining ring 11 is removed, while the other end remains connected to the first retaining ring 10. Under the action of gravity (due to the offset of the weight of the abutment block), the flip plate 6 naturally rotates to the horizontal and abuts against the rocker frame 3, forming a stable platform.
[0066] The procedure for using this device is as follows:
[0067] When an infant cries, the caregiver needs to prepare appropriate items to care for the infant. If the crying cannot be stopped immediately, the caregiver should first press the corresponding button to activate the two sets of rocking components 4. Based on the aforementioned linkage between the various components, the two sets of rocking components 4 cause the rocking frame to move back and forth rhythmically (including changes in height), slightly distracting the infant and reducing or decreasing the crying. During this period, the caregiver should prepare the necessary items (such as diapers, bottles, changes of clothes, bowls, etc.) and bring them all to the vicinity of the crib for easy care of the infant.
[0068] After quickly obtaining the necessary items, the caregiver approaches the crib to prevent prolonged crying. First, they press the button again to stop the rocker frame from moving. Then, the hook spring 9 is removed from the end located on the second retaining ring 11. Without the resistance of the rocker frame 3 against the hook spring 9, the flap 6 falls naturally under its own weight. Due to the presence of the abutment block, the overall weight of the flap 6 and the abutment block is uneven, tilting towards one side. Therefore, the flap 6 and the abutment block can only rotate to one side. Finally, the abutment block abuts against the end face of the rocker frame 3, forming a platform for placing items. The platform is made of high-strength aluminum alloy, with a load-bearing capacity exceeding 10kg, meeting the aforementioned load-bearing requirements in practice. The caregiver can place the aforementioned items, such as baby bottles, food bowls, changes of clothes, and diapers, on this platform. Then, the caregiver can lift the baby from the crib to care for the infant. If needed, the corresponding item can be directly retrieved from the platform, allowing for convenient access to all items at once and eliminating the need for multiple trips during changes, thus making infant care more convenient. After the platform is finished using it, the caregiver should manually rotate it to a vertical position and reconnect the hook at one end of the hook spring 9 to the second retaining ring 11.
[0069] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
