Title: Intelligent baby crib

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to the technical field of baby cribs, and more particularly, to an intelligent baby crib. 
     BACKGROUND OF THE INVENTION 
     A baby crib is a small bed especially designed for infants and very young children. The marketplace is filled with a great variety of baby cribs with styles and features. 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&#39;s diaper and lull the baby back to sleep again, making the parents exhausted. 
     Presently, some baby cribs sold on the market possess functions such as automatic swinging, music playing, monitoring and alarming, alleviating the caregiver&#39;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. 
     In conclusion, the shortcomings of traditional baby cribs are urgent problems that need to be solved for those skilled in this field.

     DETAILED DESCRIPTION OF THE INVENTION 
     Drawings and detailed embodiments are combined hereinafter to elaborate the technical principles of the present invention. 
     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&#39;s head and body during sleep, thereby solving the problems relating to milk-vomiting and difficult breathing due to the baby&#39;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. 
     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&#39;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. 
     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. 
     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&#39;s sleeping postures can be achieved. 
     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 telescopic connecting rod  3  comprises a hinge sleeve  31 , a guiding sleeve  32  and a telescopic rod  33 .

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. 
     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. 
     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 . The elevating worm  62 , which is vertically inserted into the worm shaft sleeve  61 , is engaged with the worm shaft sleeve  61  therein.
