Although their prices and functions are very different, safety and practicability are always regarded as key factors for selecting a baby crib. Traditional baby cribs sold on the market provide various choices and experiences to the users. When lulling a baby to sleep, a caregiver usually shakes the baby crib or sings a lullaby. However, the baby needs to be constantly nursed even when he/she falls asleep. For instance, a baby soiled diaper will probably baby wake up and cry at any time even during the night. At this time, the parents must immediately replace the baby's diaper and lull the baby back to sleep again, making the parents exhausted.

[0003] Presently, some baby cribs sold on the market possess functions such as automatic swinging, music playing, monitoring and alarming, alleviating the caregiver's burden to a certain degree. However, their structures are not reasonable, leading to several problems. For instance, a baby may frequently roll over in the baby crib. When the baby turns to sleep on her side, instead of lying on her back, the height of her head can be changed accordingly. However, the bed plate of the traditional baby crib cannot be regulated according to her physical movements, resulting in problems relating to milk-vomiting or difficult breathing, creating more stress for the parents. Moreover, some baby cribs capable of automatically swinging usually adopt an arc-shaped slide structure as the main frame, thereby supporting and enabling the bed plate to roll on the slide back and forth. Such a design is not humanized, and has shortcomings, such as complicated structure and difficult control of swing range and frequency, resulting in limited functions and low level of intelligence.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Drawings and detailed embodiments are combined hereinafter to elaborate the technical principles of the present invention.

[0024] The intelligent baby crib of the present invention comprises a base 6 and a bedstead 1. A bottom chamber 11, which is disposed in the middle of the bedstead 1, is downwardly recessed. A bed plate 2 is disposed at the upper end opening of the bottom chamber 11. A swing mechanism is disposed between the bed plate 2 and the bedstead 1. A stretching mechanism is disposed on the bottom surface of the bed plate 2. An elevating mechanism is disposed on the base 6, and the upper end of the elevating mechanism is connected to the bottom of the bedstead 1. The main purposes of the present invention are: first, the height of the bedstead 1 can be regulated on the base 6, enabling the caregiver to conveniently nurse the baby at a proper height; second, the bed plate 2 can be stretched and deformed back and forth to regulate the height difference between the baby's head and body during sleep, thereby solving the problems relating to milk-vomiting and difficult breathing due to the baby's sleeping postures; third, the bed plate 2 can swing left and right on the bedstead 1, thereby creating a comfortable sleeping environment for the baby. Thus, the time and labor consumed by manually shaking the baby crib can be saved. An armrest portion 12 is disposed at the rear end of the bedstead 1, and a control panel 13 and a music player are disposed on the armrest portion 12. The control panel 13, which is disposed on the upper end surface of the armrest portion 12, is electrically connected to the music player, the swing mechanism, the stretching mechanism and the elevating mechanism through connecting wires. The baby crib of the present invention is equipped with moving components capable of greatly improving the portability of the baby crib, thus enabling the baby to be conveniently nursed during outdoor activities. The integrated control panel is placed on the armrest portion 12, which can significantly enhance the operating convenience.

[0025] All of the vertical sections of the bed plate 2 are recessed and arc-shaped, making the bed plate to be an arc-shaped integral structure. The arc-shaped bed plate 2 can ensure that the baby's head is always kept higher than his/her body. Thus, a newborn infant can be kept lying on his/her back, effectively reducing the frequency of turning or rolling over. Consequently, problems relating to milk-vomiting and difficult breathing during sleep can be effectively solved.

[0026] Furthermore, the bed plate 2 comprises a front base plate 21, a rear base plate 22 and a plurality of transitional base plates 23. The plurality of transitional base plates 23 is sequentially hinged to form an integral linking structure. The first transitional base plate 23 and the last transitional base plate 23 are respectively hinged to the front base plate 21 and the rear base plate 22. The front base plate 21 and the rear base plate 22 are respectively provided with a telescopic connecting rod 3 that is connected to the bedstead 1. The telescopic connecting rod 3 is a direction-varying connection member, allowing the bed plate 2 to longitudinally stretch and deform on the bedstead 1, and transversely swing left and right.

[0027] The aforesaid stretching mechanism comprises a worm motor 41, a supporting frame 24 and a transmission shaft 42. The supporting frame 24 is fixed to the bottom surface of the rear base plate 22. The two ends of the transmission shaft 42 are respectively inserted into the supporting frame 24, and are rotationally connected to the supporting frame 24. A transmission gear 43 is disposed on the transmission shaft 42, and the two ends of the transmission shaft 42 are respectively provided with a driving pulley 44. The worm motor 41 is fixed to the rear base plate 22, and the output shaft of the worm motor 41 is engaged with the transmission gear 43. The worm motor 41 is electrically connected to the control panel 13 through a connecting wire. The bottom surface of the rear base plate 21 is provided with a driven wheel group 45. An auxiliary wheel group 46 is disposed on each bottom surface of the plurality of transitional base plates 23. A transmission string 47 is connected between the driving pulley 44 and the driven wheel group 45. The transmission string 47, which sequentially passes through the transitional base plates 23, is drive-connected to each auxiliary wheel group 46 on the transitional plates. The front base plate 21, the plurality of transitional base plates 23, and the rear base plate 22 are sequentially connected to form the integral base plate 2. In an initial state, the vertical section of the base plate 2 is arc-shaped, and the transmission string 47 is placed along the bottom surface of the bed plate 2. Meanwhile, the length of the transmission string 47 is matched to the arc length of the section of the base plate 2. When the driving pulley 24 is propelled by the worm motor 41 to rotate, the transmission string 47 placed between the driving pulley 44 and the driven wheel group 45 is shortened. Consequently, the integrally-linked bed plate can be turned over, enabling the relative heights between the front base plate 21, the plurality of transitional base plates 23, and the rear base plate 22 to be evened. Therefore, the purpose of regulating the baby's sleeping postures can be achieved.

[0028] Additionally, the front base plate 21 and the rear base plate 22 are respectively provided with a telescopic connecting rod 3 that is connected to the bedstead 1. The two telescopic connecting rods 3 are respectively disposed on the center lines of the front base plate 21 and the rear base plate 22.

The output shaft of the driving motor 51 is provided with a rotor 52, and the rotor 52 is provided with a lifting lever 53 that is eccentrically disposed with the output shaft of the driving motor 51. The pedestal 54, which is fixed to the bottom surface of the bed plate 2, is a hollow structure having an opening at the lower end. The fitting cover 55 is fixed at the lower end opening of the pedestal 54. The base plate of the fitting cover 55 is provided with a straight groove 56. The upper end of the lifting lever 53 passes through the straight groove 56, and is movably disposed in the pedestal 54. The driving motor 51 takes the output shaft as the center to propel the lifting lever 53 to eccentrically rotate, and the lifting lever 53 coordinates with the fitting cover 55 to propel the bed plate 2 to reciprocate left and right, thereby shaking the baby crib and lulling the baby to fall asleep. Consequently, the parents do not have to work as hard to put the baby to sleep. The swing frequency can be changed through regulating the rotating speed of the driving motor 41. The eccentric diameter of the lifting lever 53 can be regulated through changing the rotor 52, and the length of the straight groove 56 can be changed through replacing the fitting cover 55. Thus, the swing range of the bed plate 2 can be regulated.

[0030] Preferably, the fitting cover 55 is made from materials capable of being elastically deformed. The edges of the lifting lever 53 and the straight groove 56 are treated by abrasion-reducing and wear-resisting processes. Meanwhile, the width of the straight groove 56 is slightly greater than the diameter of the lifting lever 53. The length of a portion of the lifting lever 43 that is inserted into the straight groove 23 is greater than the chord height of the moving path of the fitting cover 55 when the bed plate 2 swings.

[0031] The elevating mechanism comprises a worm shaft sleeve 61, an elevating worm 62 and an elevating motor 63. The worm shaft sleeve 61 is fixed to the upper end of the base 6.
