Abstract

The utility model discloses a novel automatic cradle. An inner cradle is hung on an outer frame through four connecting rods, therefore, the inner cradle can freely swing; the lower end of one of four connecting rods extends and is connected with a pulley through a hinge chain; a reducing motor fixed on the outer frame can drive a cam fixedly connected to the shaft of the motor to conduct circular rotation when the reducing motor is started; and a groove is formed in the middle of the cam and a pulley is sunk into the groove;. Along the rotation of the cam driven by the reducing motor, the pulley moves in the groove and drives the connecting rods to conduct periodical swing; when the connecting rods are in the vertical state, the cam is in the lowest position; when the connecting rods are in a right limit position or a right limit position, the cam and the pulley are in contact with each other in the farthest position, thereby realizing the horizontal swing of the inner cradle, realizing the intellectualization, saving the manual work, and realizing simple and feasible structure.

Description

A kind of new type auto cradle

Technical field

The utility model relates to a kind of automatic cradle.

Background technology

At present, the cradle that can buy on the market be all need artificial hand, present stage manual resource most deficient, under the prerequisite that human cost improves constantly, the extremely waste that seems of artificial cradle; And only allow the elderly band baby that is in, it is also very painstaking to swagger basket for a long time, is unfavorable for the elderly's physical and mental health.Therefore, cradle realizes that motorized, automation, intellectuality are very important.Though various electric cradle, intelligent cradle patent were also arranged by application in the most several years, most of structures are extremely unreasonable, do not conform with the pattern of traditional cradle, make that baby's rocking in cradle is very uncomfortable, sleeping not stable; Some intelligent cradle structure is extremely complicated, is difficult for implementing, and therefore, does not also have real intelligent cradle to enter and produces and the market stage.

Summary of the invention

The purpose of this utility model is to provide a kind of device that makes that cradle waves automatically, has greatly reduced human cost.

The technical solution adopted in the utility model is:

Interior cradle is hung on the outer basket by four connecting rods, therefore cradle can freely swing in, extend a lower end in while four connecting rods and hinge connects pulley, start to be fixed on the reducing motor on the outer basket and to drive the cam that is connected on it and do the turnover motion, one groove is arranged in the middle of the cam, pulley is absorbed in the groove, drive the rotation of cam along with reducing motor, thereby pulley will be made periodic wobble at groove the inside motion drivening rod, when connecting rod is vertical, cam is positioned at extreme lower position, and when connecting rod was in left and right sides two limit positions, cam contacted at highest distance position with pulley.Thereby cradle is vacillated now to the left, now to the right in realizing, has realized intellectuality, saved manually, and simple in structure feasible.

For realize cradle about two extreme position pendulum angles identical, must be being centered close under connecting rod vertical of reducing motor, its amplitude of swinging will equate like this.

The specific embodiment

At Fig. 1, among Fig. 2, interior cradle (7) is hung on the outer basket (6) by four connecting rods (4) (5) (8) (9), therefore cradle (7) can freely swing in, extend connecting rod (5) lower end and hinge connects pulley (3), outer basket (6) is gone up fixedly reducing motor (2), cam (1) is connected on reducing motor (2) axle, one groove is arranged in the middle of the cam (1), pulley (3) is absorbed in the groove, start reducing motor (2), the cam (1) that is connected thereon will be done the turnover rotation along with the rotation of reducing motor (2), and pulley (3) will be in the motion of groove the inside, thereby drivening rod (5) is made periodic wobble, and cradle is vacillated now to the left, now to the right in realizing.

When connecting rod (5) was vertical, cam (1) just went to extreme lower position, and when connecting rod (5) was in left and right sides two limit positions, cam (1) contacted at highest distance position with pulley (3).

In Fig. 3, after plugging in,, can press switch (11) when the baby wants in bed, on timer (10), configure the time that need wave, reducing motor (2) begins to rotate; When after sleep prevention in evening baby sleeps, needing to shake, plug in cut-off switch (11), press switch (12), cry after evening, the baby woke up, vagitus testing circuit (13) will detect signal, thereby the connection circuit waved according to the time that configures previously.

Claims

1, a kind of new type auto cradle, it is characterized by: interior cradle (7) is hung on the outer basket (6) by four connecting rods (4,5,8,9), extend connecting rod (5) lower end and hinge connects pulley (3), reducing motor (2) is fixed on the outer basket (6), cam (1) is connected on reducing motor (2) axle, in the middle of the cam (1) groove is arranged, pulley (3) is absorbed in the groove.

2, a kind of new type auto cradle according to claim 1 is characterized in that: the center of reducing motor (2) connecting rod (5) upper end with outside under basket (6) tie point place vertical.
