Description

{A electronin cradle}

The present invention relates to an electric cradle.

The cradle used for the sleeping of the infant is provided in a basket form, and a cushion material such as a blanket is provided inside. Infants who are sleeping in these cradles are generally unable to properly share their bodies and spend most of their time sleeping. At this time, there is a concern that the infant may suffocate in the process of turning over or turning over.

Conventionally, in order to prevent such asphyxiation, a sensor is attached to a cradle, and a warning signal is transmitted to a guardian in case of a choking situation, thereby informing the danger thereof.

However, this method has a limit in that it takes time until the guardian arrives at the infant so that proper response can be delayed.

Accordingly, an object of the present invention is to provide an electric cradle which can effectively prevent sudden death of a child with a relatively simple structure.

In order to achieve the above object, according to the present invention, there is provided an electric cradle comprising: a cradle body having an infant receiving portion; A sleeping position correcting unit provided in the infant accommodating unit to support the infant, and a sleeping position correcting unit capable of selectively raising and lowering a region of mutually oppositely spaced positions with respect to the longitudinal axis of the pad unit.

Preferably, the sleep / posture correcting section has at least a pair of elevating members arranged to face each other with respect to the longitudinal axis.

It is preferable that the elevating member is a cam, and the water level posture correcting section has a camshaft for connecting and rotating the cam, and a driving motor for rotating the camshaft. Whereby a specific region of the pad unit can be selectively lifted and lowered.

And a state detection sensor for sensing a state of the infant on the pad unit; Further comprising a control unit for determining whether the posture of the infant is in a dangerous state based on a signal from the state detection sensor and controlling the sleeping posture correcting unit to change the posture of the infant when judged to be in a dangerous state, So that the risk can be prevented in advance.

Here, the state detection sensor unit may include a camera, and the controller may determine the state of the infant based on the video signal from the video signal from the camera.

In addition, the condition sensor further includes a pulse sensor and an oxygen saturation sensor. If the input value is less than a set value initially stored in the pulse rate and oxygen saturation received through the pulse sensor and the oxygen saturation sensor, It is possible to judge the state of the infant more accurately and cope with it.

According to the present invention described above, the electric cradle can effectively prevent the sudden death of the infant. Also, the manufacturing cost and the management cost can be reduced with a relatively simple structure.

As shown in Figs. 1 and 2, the electric cradle has a cradle body 100 having an opening at its upper side and having an infant receiving portion therein, and a sleeping position correcting unit 130 provided in the cradle body 100. Fig.

The cradle body 100 is formed in a curved shape as a whole such that the baby or the protector is not injured by collision with an edge or the like. A pad unit (110) is provided inside the infant storage unit to support the infant. Since the pad unit 110 is a portion directly contacting the baby's skin, it is preferable that the pad unit 110 is made of a cotton material having excellent stretchability and breathability.

An operation input unit 150 is provided at one side of the cradle main body 100. In the operation input unit 150, the period and amplitude of the cradle swing are adjusted, and a condition for generating an alarm signal of a control unit, which will be described later, and an alarm signal to be received can be specifically set. This allows the electric cradle to provide various swing modes and specific alarm signals according to the needs of the guardian and the manager.

As shown in FIG. 2, a child placed on the pad unit 110 senses the state of the infant through the state detection sensor unit 200. The state detection sensor unit 200 includes a camera 210, a pulse sensor 220, and an oxygen saturation sensor 230, all or in part. In some cases, a sensor such as a temperature sensor or a humidity sensor other than the camera 210, the pulse sensor 220 and the oxygen saturation sensor 230 may be further included to acquire additional information about the environment of the infant.

The camera 210 is provided at the upper end of the cradle body 100, and photographs the state of the infant in real time. Based on the video signal of the camera 210, the controller 400 can determine whether the current state of the infant is a safe state or a dangerous state. Here, the camera 210 may be provided with an infrared camera and a thermal camera.

The pulse detecting sensor 220 and the oxygen saturation sensor 230 are provided in the cradle body 100 and serve as a basis for judging the state of the infant through contact with or contact with the infant. When the input values of the measured pulse sensor 220 and the oxygen saturation sensor 230 fall below a set value of the set pulse and oxygen saturation, the controller determines that the present infant condition is in a dangerous state and generates a sleep posture correcting signal And sends it to the sleeping position correcting unit 130.

According to this configuration, the control unit 400 transmits the state information of the infant, which is a combination of at least one of the camera 210, the pulse sensor 220 and the oxygen saturation sensor 230, to the controller 400. Based on the information transmitted from the state detection sensor unit 200, the controller 400 determines the state of the infant. If it is determined that the infant's state is a dangerous state due to suffocation, the danger alert is notified to the smart device of the administrator and the guardian through the communication unit 500 and simultaneously, And drives the provided sleeping position correcting unit 130.

3 to 5 are views showing an embodiment of a sleep posture correcting unit according to the present invention. As shown in these drawings, the sleeping position correcting unit 130 can selectively lift and lower the region of the position spaced apart from the longitudinal axis of the pad unit 110. [ The sleeping position correcting unit 130 forms a pair of elevating members disposed to face each other with respect to the vertical axis, and can be variously implemented through embodiments to be described later.

As the first embodiment of the sleeping position correcting unit 130 shown in FIG. 3, the elevating member of the sleeping position correcting unit 130 is formed of the cam unit 133. [ The cam unit 133 has a cam shaft 136 which rotates integrally with the cam 134 and a driving motor 135 provided at one end of the cam shaft 136 to drive the cam shaft 136.
