Technical Field
[0001] This utility model relates to the field of baby crib technology, and in particular to a solid wood baby crib with a parent-child interaction device. Background Technology
[0002] Solid wood cribs with parent-child interaction features aim to provide a safe and comfortable growth space for babies aged 0-3 years through technology and human-centered design, while greatly improving the quality of parent-child interaction and childcare convenience. Solid wood cribs can be used in home daily care and parent-child interaction scenarios.
[0003] The rocking function of existing cribs with parent-child interaction devices mostly relies on manual or mechanical transmission, which is time-consuming, laborious, and prone to noise. Furthermore, the protective function of the crib side rails contradicts the obstacles to use they cause.
[0004] To address the aforementioned issues, we propose a solid wood crib with a parent-child interaction device. Utility Model Content
[0005] The purpose of this utility model is to solve the problems in the background art by proposing a solid wood baby bed with a parent-child interaction device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a solid wood baby crib with a parent-child interaction device, comprising a bed frame and a bed board. Two arc-shaped rocking plates are installed at the bottom of the bed legs of the bed frame. A first support plate is fixedly connected between the two arc-shaped rocking plates. Two sets of symmetrically arranged pneumatic mechanisms are provided on the outer walls of both ends of the first support plate. The pneumatic mechanism includes an air pump and a two-position three-way solenoid valve fixedly connected to the outer wall of the first support plate. An air supply pipe is installed between the output end of the air pump and the air inlet end of the two-position three-way solenoid valve. The bottom of the arc-shaped rocking plate is provided with a groove. Each of the two arc-shaped rocking plates has an air bag in its groove. The air bag is connected to the air outlet end of the two-position three-way solenoid valve through an air inlet pipe. The air bag is connected to the exhaust end of the two-position three-way solenoid valve through an exhaust pipe.
[0007] In the aforementioned solid wood baby crib with a parent-child interaction device, two sets of horizontally arranged lifting mechanisms are provided under the bed board. Each lifting mechanism includes a guide rail groove fixed to the inner side of the bed frame. A bidirectional threaded rod is provided in the guide rail groove. The two ends of the bidirectional threaded rod are threadedly connected to a first slider and a second slider. A first limiting block and a second limiting block are respectively provided on both sides of the bidirectional threaded rod. The first slider is rotatably connected to a first support rod through a first hinge seat. The second slider is rotatably connected to a second support rod through a second hinge seat. The top ends of the first support rod and the second support rod are rotatably connected to a third hinge seat. The top end of the third hinge seat is fixedly connected to a second support plate. The top surface of the second support plate is fixedly connected to the bottom surface of the bed board. One end of the bidirectional threaded rod passes through the bed frame and is fitted with a pulley. In one set of the lifting mechanisms, the end of the bidirectional threaded rod passing through the bed frame is fixedly connected to a rotating handle. A belt is fitted on the pulleys of both sets of lifting mechanisms.
[0008] In the aforementioned solid wood baby crib with a parent-child interaction device, wheel frames are rotatably connected to both ends of the arc-shaped rocker, universal wheels are rotatably connected to the bottom end of the wheel frames, and limit posts are fixedly connected to the inner wall of the wheel frames.
[0009] In the aforementioned solid wood baby crib with a parent-child interaction device, a guardrail is fixedly connected to the perimeter of the crib frame, an elastic bar is fixedly connected to the outer wall of the guardrail, and a retaining ring is fixedly connected to the end of the elastic bar.
[0010] In the aforementioned solid wood baby crib with parent-child interaction device, the bed frame, bed board, curved rocking board, and guardrail are all made of formaldehyde-free environmentally friendly hard solid wood.
[0011] In the aforementioned solid wood crib with parent-child interaction device, both the first support rod and the second support rod are made of high-strength aluminum alloy.
[0012] Compared with existing technologies, the advantages of the solid wood baby crib with parent-child interaction device provided by this utility model are as follows:
[0013] The air pump inflates the airbag through the inflation passage of the two-position three-way solenoid valve, causing the right side of the curved rocker to rise. Due to the curved design of the rocker, the bed frame tilts to the left. Then, the two-position three-way solenoid valve switches to the exhaust passage. Due to the weight of the bed frame and the pressure inside and outside the airbag, the gas in the airbag is automatically discharged, the curved rocker falls back, and the center of the bed frame moves back. It tilts to the right due to inertia. By constantly switching the air passage, the inflation and deflation actions are alternately performed, forming a left-right rocking motion, realizing the automatic rocking of the crib.
[0014] 2. When the bed board needs to be raised, the operator turns the rotary handle clockwise, causing the double-sided threaded rod to rotate. The first and second sliders move towards each other, reducing the angle between the first and second support rods, which in turn raises the second support plate, thus raising the bed board. At the same time, the first limit block prevents the first slider from moving, and the second limit block prevents the second slider from moving, preventing the bed board from rising too high and causing an accident. When the bed board needs to be lowered, the operator turns the rotary handle counterclockwise, causing the double-sided threaded rod to rotate in the opposite direction. The first and second sliders move in the opposite direction, increasing the angle between the first and second support rods, which in turn lowers the second support plate, thus lowering the bed board. By raising and lowering the bed board, the height of the bed board can be adapted to the operator's needs.
[0015] In summary, this utility model frees up the hands by adding a pneumatic rocking structure to the baby crib, saving time and effort. The pneumatic device is quieter, and the lifting of the bed board adapts to the needs of the operator, thus resolving the contradiction between the protective function of the guardrail and its obstruction of use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 A solid wood baby crib with a parent-child interaction device includes a bed frame 1 and a bed board 2. Two curved rocking plates 3 are installed at the bottom of the legs of the bed frame 1. A first support plate 4 is fixedly connected between the two curved rocking plates 3. Two sets of symmetrically arranged pneumatic mechanisms are provided on the outer walls of both ends of the first support plate 4. The pneumatic mechanism includes an air pump 5 and a two-position three-way solenoid valve 6 fixedly connected to the outer wall of the first support plate 4. An air supply pipe 7 is installed between the output end of the air pump 5 and the air inlet end of the two-position three-way solenoid valve 6. The bottom of the curved rocking plates 3 has a groove, and each of the two curved rocking plates 3 has an airbag 8 in the groove. The airbag 8 is connected to the two-position three-way solenoid valve 6 through an air inlet pipe 9. The air outlet of the solenoid valve 6 and the airbag 8 are connected to the exhaust end of the two-position three-way solenoid valve 6 through the exhaust pipe 10. The air pump 5 inflates the airbag 8 through the inflation passage of the two-position three-way solenoid valve 6, causing the right side of the arc-shaped rocker 3 to rise. Due to the curved design of the arc-shaped rocker 3, the bed frame 1 tilts to the left. Then the two-position three-way solenoid valve 6 switches to the exhaust passage. Due to the weight of the bed frame 1 and the internal and external pressure of the airbag 8, the gas in the airbag 8 is automatically discharged, the arc-shaped rocker 3 falls back, causing the center of the bed frame 1 to shift back and tilt to the right due to inertia. By continuously switching the air passage, the inflation and deflation actions are alternately performed, forming a left-right rocking motion, realizing the automatic rocking of the crib.
[0023] Two sets of horizontally arranged lifting mechanisms are provided below the bed board 2. Each lifting mechanism includes a guide rail groove 11 fixed to the inner side of the bed frame 1. A bidirectional threaded rod 12 is provided within the guide rail groove 11. The two ends of the bidirectional threaded rod 12 are threadedly connected to a first slider 13 and a second slider 14. A first limiting block 22 and a second limiting block 23 are respectively provided on both sides of the bidirectional threaded rod 12. The first slider 13 is rotatably connected to a first support rod 16 via a first hinge seat 15. The second slider 14 is rotatably connected to a second support rod 18 via a second hinge seat 17. A third hinge seat 20 is rotatably connected to the top of the first support rod 16 and the top of the second support rod 18. A second support plate 21 is fixedly connected to the top of the third hinge seat 20. The top surface of the second support plate 21 is fixedly connected to the bottom surface of the bed board 2. One end of the bidirectional threaded rod 12 passes through the bed frame 1 and is fitted with a pulley 24. A rotating handle 25 is fixedly connected to the end of the bidirectional threaded rod 12 passing through the bed frame 1 in one set of lifting mechanisms. The pulleys of both sets of lifting mechanisms... The bed board 24 is equipped with a belt 26. When the bed board 2 needs to be raised, the operator rotates the handle 25 clockwise, which drives the double-threaded rod 12 to rotate. The first slider 13 and the second slider 14 move towards each other, and the angle between the first support rod 16 and the second support rod 18 decreases, which drives the second support plate 21 to rise, thus raising the bed board 2. At the same time, the first limit block 22 prevents the first slider 13 from moving, and the second limit block 23 prevents the second slider 14 from moving, preventing the bed board 2 from rising too high and causing an accident. When the bed board 2 needs to be lowered, the operator rotates the handle 25 counterclockwise, which drives the double-threaded rod 12 to rotate in the opposite direction. The first slider 13 and the second slider 14 move in the opposite direction, and the angle between the first support rod 16 and the second support rod 18 increases, which drives the second support plate 21 to fall, thus lowering the bed board 2. By raising and lowering the bed board 2, the height of the bed board 2 can be adapted to the needs of the operator. The first support rod 16 and the second support rod 18 are both made of high-strength aluminum alloy to ensure the load-bearing stability during operation.
[0024] The two ends of the curved rocker 3 are rotatably connected to wheel frames 27, and the bottom of the wheel frames 27 is rotatably connected to casters 28. The inner wall of the wheel frames 27 is fixedly connected to a limit post 29. When the wheel frames 27 rotate downwards, the limit post 29 and the bottom surface of the curved rocker 3 are in contact and positioned, and the casters 28 touch the ground, which can push the crib to move. When the wheel frames 27 rotate upwards, the limit post 29 and the top surface of the curved rocker 3 are in contact and positioned, the casters 28 are retracted, and the curved rocker 3 touches the ground.
[0025] The bed frame 1 is fixedly connected to a guardrail 30, and an elastic rod 31 is fixedly connected to the outer wall of the guardrail 30. A retaining ring 19 is fixedly connected to the end of the elastic rod 31. The retaining ring 19 holds a bell or a toy. When the elastic rod 31 is touched lightly, the toy will swing elastically, allowing for close interaction with the baby on the bed.
[0026] The bed frame 1, bed board 2, curved rocking board 3, and guardrail 30 are all made of formaldehyde-free, environmentally friendly hard solid wood, protecting the baby's health.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
