Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to the technical field of baby
cribs, and more particularly, to an intelligent baby crib.
BACKGROUND OF THE INVENTION
[0002] 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'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.
[0004] In conclusion, the shortcomings of traditional baby cribs
are urgent problems that need to be solved for those skilled in
this field.

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

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 telescopic

and the other end of the telescopic rod 33 is connected to the
bedstead 1. The hinge sleeve 31 is connected to the front base
plate 21 or the rear base plate 22, which can coordinate with each
other to rotate on the transverse plane. Through the connection
between the guiding sleeve 32 and the telescopic rod 33, the hinge
sleeve 31 enables the bed plate 2 to rotate and move on the
longitudinal plane.
[0029] The swing mechanism comprises a driving motor 51, a pedestal
54 and a fitting cover 55. The driving motor 51 is disposed on the
base plate of the bedstead 1 in the center of the bottom chamber
11. The driving motor 51 is electrically connected to the control
panel 13 through a connecting wire. 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

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

voice frequency recognizer 18. The bedstead 1 and the bed plate 2
are provided with a plurality of sensors. The control panel 13 is
provided with a monolithic processor 14. The monolithic processor
14 is separately connected to the voice frequency recognizer 18 and
the plurality of sensors through data lines. The voice frequency
recognizer 18 can recognize a baby's voice, and the plurality of
sensors includes a heartbeat monitoring sensor, a humidity sensor,
and a temperature sensor. The monolithic processor 14 can receive
and logically judge the signals transmitted by the voice frequency
recognizer 18 and the plurality of sensors, and give corresponding
orders to the control panel 13, thus controlling the control panel
to display the data being monitored such as temperature, humidity
and heartbeat. Consequently, the fan 16, the swing mechanism, the
stretching mechanism and the music player are activated to work,
playing music or initiating the calling system to alarm the
caregiver.
