summary of the invention:
the object of this invention is to provide a kind of rhythmical child of patting to the baby sleep assistor and the method that make baby enter sleep as early as possible.
above-mentioned object is realized by following technical scheme:
a kind of baby sleep assistor, its composition comprises: with the motor of single-chip computer control system, described motor Connectable umbrella gear train, and described bevel gear group connects cam, described cam is equipped with swing arm with the cam side described in spacer pin, and described swing arm connects bounces spring.
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 engages horizontal bevel gear, the power output shaft described in described horizontal bevel gear connects, the cam described in described power output shaft connects.
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, spring one end is bounced described in described hook connects, 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 aid resistance arm.
described baby sleep assistor, the long 60mm of described shell, wide 41mm, described Power output shaft diameter is 26mm, described swing arm is curved swing arm, and the length of the tail end that described curved swing arm divides from described rotating shaft junction to described housing exterior is 70mm; 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 works, and claps on the body of baby, then bounces spring and pull swing arm to bounce, work next time, constantly clap on the body of baby.
the method of described baby sleep assistor, cam stirs the swing arm by spacer pin restriction stroke, gear train is arranged in housing, gear train engages each other by two, axially becomes the vertical bevel gear of an angle of 90 degrees and horizontal bevel gear to form, vertical bevel gear and horizontal bevel gear are arranged on decelerating step motor output shaft respectively and with on power output shaft, power output shaft connects cam; Clapping arm is connected on sleep aid resistance arm, what the termination of clapping arm had rubber to make has clapping hands of simulation staff beating, clap hands by decelerating step motor and connected gear-box, the cam driven be arranged on gear-box power output shaft, clap hands and carry out bouncing action carry out back and forth patting dynamic continuously by bouncing spring.
beneficial effect:
1. swing arm of the present invention can rhythmically be patted on the body of child, the hands being similar to mother is to pacify child the same, periodic rhythm can impel child to fall asleep as soon as possible, can save time and the muscle power of adult, and can observe the same thing doing other at present of child simultaneously.
what the present invention adopted bounces spring swing arm can be made to bounce accurately, makes that swing arm is rhythmical to be patted on the body of child, and light, heavy appropriateness, pats effective, child can be helped to enter sleep as early as possible.
the present invention can play to child as toy when not starting switch, increases the enjoyment of child, reduces the labor intensity of adult.
the all parts of the present invention are all contained in housing, safety, stable, effective, and structure is simple, cost is low, applied widely.
what the present invention adopted bounce spring and spacer pin can make swing arm move according to certain track, accurately, dynamics moderate pat baby, fall fast and start slow, to the beating action emulation of natural person.
