described baby sleep assistor, described bevel gear group has bevel gear group housing, described bevel gear group comprises vertical bevel gear, described vertical bevel gear is contained on described decelerating step motor output shaft, described decelerating step motor output shaft connects power output shaft, described vertical bevel gear meshes horizontal bevel gear, and described horizontal bevel gear connects described power output shaft, and described power output shaft connects described cam.
described baby sleep assistor, described cam, it is described that to bounce spring cased, a described swing arm part is in described shell, described swing arm another part is outside described shell, the part connection rotating shaft of described swing arm in described shell, described rotating shaft coupling hook, described hook connects described spring one end that bounces, the described spring other end that bounces is fixed on described shell, described shell has opening, described A/F meets the amplitude of oscillation of described swing arm, described swing arm front end has clapping hands of simulation staff beating, described swing arm rear end has sleep assistor resistance arm.
described baby sleep assistor, the long 60mm of described shell, wide 41 mm, described power output shaft diameter is 26 mm, described swing arm is bent type swing arm, and the length of the tail end that described bent type swing arm divides to described housing exterior from described rotating shaft junction is 70 mm; Described rotating shaft diameter is 40mm.
a kind of method of baby sleep assistor, decelerating step motor is switched on power, decelerating step motor drives the work of bevel gear group, bevel gear group band moving cam rotates, cam driven swing arm outer end work, clap on baby's body, then bounce spring and pull swing arm to bounce, work next time, constantly clap on baby's body.
the method of described baby sleep assistor, cam is stirred the swing arm that is subject to spacer pin restriction stroke, gear train is arranged in housing, gear train vertical bevel gear and horizontal bevel gear intermeshing by two, that axially become an angle of 90 degrees form, vertical bevel gear and laterally bevel gear be arranged on respectively the decelerating step motor output shaft and with power output shaft on, power output shaft connects cam; Clapping arm is connected on sleep assistor resistance arm, the termination of clapping arm has that rubber makes has clapping hands that the simulation staff pats, clap hands by decelerating step motor and connected gear-box, be arranged on the cam driven on the gear-box power output shaft, clap hands and bounced action and carry out continuously back and forth patting moving by bouncing spring.
beneficial effect:
1. swing arm of the present invention can rhythmically be patted on child's body, the hands that is similar to mother is to pacify child the same, periodically rhythm can impel child to fall asleep as soon as possible, can save adult's time and muscle power, and can observe child's the same thing of doing at present other simultaneously.
the present invention adopts bounces spring and can make swing arm bounce accurately, makes that swing arm is rhythmical to be patted on child's body, and light, heavy appropriateness is patted effectively, can help child to enter as early as possible sleep.
the present invention can play to child as toy when starting switch not, increases child's enjoyment, reduces adult's labor intensity.
the all parts of the present invention all are contained in housing, safe, stable, effective, simple in structure, cost is low, applied widely.
the present invention adopts bounces spring and spacer pin can make swing arm be moved according to certain track, accurately, dynamics moderate pat the baby, fall fast and start slow, to natural person's beating action emulation.
the specific embodiment:
embodiment 1:
a kind of baby sleep assistor, its composition comprises: with the motor 1 of single-chip computer control system, described motor Connectable umbrella gear train, described bevel gear group connects cam 2, described cam is equipped with swing arm 4 with described cam one side of spacer pin 3, and described swing arm connects bounces spring 5.
embodiment 2:
the described baby sleep assistor of embodiment 1, described bevel gear group has bevel gear group housing 6, described bevel gear group comprises vertical bevel gear 7, described vertical bevel gear is contained on described decelerating step motor output shaft 8, described decelerating step motor output shaft connects power output shaft 10, described vertical bevel gear meshes horizontal bevel gear 9, and described horizontal bevel gear connects described power output shaft, and described power output shaft connects described cam.
embodiment 3:
described baby sleep assistor, described cam, the described spring that bounces is contained in shell 11, a described swing arm part is in described shell, described swing arm another part is outside described shell, the part connection rotating shaft 12 of described swing arm in described shell, described rotating shaft coupling hook 13, described hook connects described spring one end that bounces, the described spring other end that bounces is fixed on described shell, described shell has opening 14, described A/F meets the amplitude of oscillation of described swing arm, what described swing arm front end had that the simulation staff pats claps hands 15, described swing arm rear end has sleep assistor resistance arm 16.
embodiment 4:
embodiment 1 or 2 or 3 described baby sleep assistors, the long 60mm of described shell, wide 41 mm, described power output shaft diameter is 26 mm, described swing arm is bent type swing arm, and the length of the tail end that described bent type swing arm divides to described housing exterior from described rotating shaft junction is 70 mm; Described rotating shaft diameter is 40mm.
embodiment 5:
a kind of method of baby sleep assistor, switch on power decelerating step motor, and decelerating step motor drives the work of bevel gear group, by bouncing spring, pull swing arm to bounce, bevel gear group band moving cam rotates, and the work of cam driven swing arm outer end, constantly clap on baby's body.
embodiment 6:
the method of the described baby sleep assistor of embodiment 5, cam is stirred the swing arm that is subject to spacer pin restriction stroke, gear train is arranged in housing, gear train vertical bevel gear and horizontal bevel gear intermeshing by two, that axially become an angle of 90 degrees form, vertical bevel gear and laterally bevel gear be arranged on respectively the decelerating step motor output shaft and with power output shaft on, power output shaft connects cam; Clapping arm is connected on sleep assistor resistance arm, the termination of clapping arm has that rubber makes has clapping hands that the simulation staff pats, clap hands by decelerating step motor and connected gear-box, be arranged on the cam driven on the gear-box power output shaft, clap hands and bounced action by bouncing spring, back and forth pat continuously.
