Technical Field

The present application relates to a technique for caring for an infant, and more particularly, to an apparatus for caring for an infant and a driving device thereof.

Background

Automation has been applied to a technique for caring for an infant, such as an automatically rocking cradle, a rocking chair or a rocking bed, which soothes an infant by a certain automatic rocking, thus allowing the infant to sooth the infant and freeing the parents' hands for the convenience of the parents. However, sensitive infants tend to prefer a unique way of soothing, not others. For example, an infant lying in a manual cradle only likes the amplitude and frequency of the shake specific to her mother, but not that of dad. In practice, the amplitude and frequency of the automatically rocking cradle may not be the type that the infant likes, and thus it is difficult for the infant to get proper care.

Therefore, there is a need to provide an improved technical solution to overcome the technical problems in the prior art.

Disclosure of Invention

The main technical problem that this application will be solved is that current equipment of looking after the baby is difficult to provide the problem that is fit for the baby's shake.

To solve the above technical problem, the present application provides, in one aspect, an apparatus for caring for infants, comprising:

a support;

a support for supporting an infant;

a driver including a drive body fixed relative to the mount and a drive shaft, the driver having a driving state in which the drive shaft outputs reciprocating rotational power within an angular range of not more than 180 degrees and a passive state in which the drive shaft is freely rotatable relative to the drive body within the angular range;

an interlocking member that is power-connected between the drive shaft and the support body, and that transmits power from the drive shaft to the support body to drive the support body to move periodically when the driver outputs power, and that transmits power from the support body to drive the drive shaft to rotate when the support body is driven by an external force when the driver does not output power;

a sensor that detects information related to displacement of a member fixed relative to the drive shaft; and

a controller electrically connected with the driver and electrically connected with the sensor.

In another aspect, the present application provides a drive apparatus comprising.

A drive housing having an accommodation space;

a driver including a driving body fixed in the accommodating space and a driving shaft, the driver having a driving state in which the driving shaft outputs a reciprocating rotational power within an angular range of not more than 180 degrees and a passive state in which the driving shaft is freely rotatable within the angular range with respect to the driving body;

a sensor which is located in the housing space and detects displacement information of a member fixed relative to the drive shaft; and

and the controller is fixed in the accommodating space, is electrically connected with the driver and is electrically connected with the sensor.

According to the technical scheme of the application, the driver has a driving state and a passive state. In the passive state, the drive shaft is free to rotate within an angular range relative to the drive body. Thus, the user may shake manually, providing a shake suitable for the baby. During manual shaking, information about the displacement of a part fixed with respect to the drive shaft can also be detected by means of a sensor. The controller is electrically connected with the driver and the sensor respectively, and self-learning can be easily realized. In the driving state, the controller may control the driver to output a shaking motion suitable for the infant according to the learned shaking. Therefore, the technical scheme of the application can easily realize the shaking suitable for the baby, and the baby rocking chair is simple in structure and easy to realize.

Detailed Description

Referring to fig. 1 to 2, an apparatus 100 for caring for infants according to an embodiment of the present application includes a support 1, a support body 2, a driver 3, a linkage member 4, a sensor 5, a controller 6, and a housing 8. The support body 2 is used for supporting an infant, for example, the support body 2 is a bed or basket for the infant to lie down, or the support body 2 is a chair or a car for the infant to sit on, or the like. The support 1 comprises a base 18 and two supports 10 spaced apart from each other. The two supports 10 standing on both sides of the base 18 may be respectively a single pillar as shown in the drawings, or may be in other forms, for example, a plate body (not shown) or a triangular frame (not shown). Wheels 16 may also be mounted below the base 18. in the embodiment of the wheels 16, the apparatus 100 for caring for infants is portable but costly. In other embodiments, the wheels 16 may not be mounted, providing a low cost solution. The support body 2 is located between two brackets 10.

A frame 10 is provided with the driver 3. The driver 3 is used for generating power, for example, the driver is an electric device, and converts electric energy into kinetic energy when being electrified. In an alternative embodiment, the two brackets 10 may be provided with a driver 3 to provide dual drive. The driver 3 includes a driving body 30 and a driving shaft 32. The drive body 30 is fixed relative to the carrier 1. For example, the driving body 30 is directly fixed to the bracket 10 of the cradle 1. Or, as shown, a drive housing 34 is secured to the frame 10 and the drive body 30 is then mounted on the drive housing 34. The driver 3 has a driving state and a passive state. In the driving state, the drive shaft 32 outputs power of reciprocating rotation in an angular range of not more than 180 degrees. For example, the driver 3 is provided with an armature (not shown), and the driving shaft 32 is controlled to reciprocate at a constant amplitude and frequency by controllably supplying electric power to the armature. The driver 3 defines an angular range in which the drive shaft 32 is operated not to exceed a predetermined angular range, for example, 175 degrees, 150 degrees, 120 degrees, 100 degrees, 80 degrees, or 60 degrees, within which power is output. In the passive state, the drive shaft 32 is freely rotatable relative to the drive body 30, at least within the aforementioned angular range. That is, the drive shaft 32 is easily rotated by an external torque, rather than being locked, and is not substantially driven by a large amount of resistance.

The linkage member 4 is power connected between the drive shaft 32 and the support body 2. For example, as shown, the linkage member 4 includes a connecting rod 40, the connecting rod 40 having a lower end connected to the support body 2 and an upper end connected to the drive shaft 32 and fixed relative to the drive shaft 32. In the driving state of the driver 3, the interlocking member 4 transmits power from the driving shaft 32 to the support body 2 to drive the support body 2 to perform a periodical rocking motion. In the passive state of the actuator 3, the support body 2 can be shaken manually. When the support body 2 is driven by an external force by a human operator, the interlocking member 4 transmits power from the support body 2 to rotate the drive shaft 32. Those skilled in the art will appreciate that linkage member 4 is not limited to a single link 40, but may be implemented in other ways. For example, a high-order mechanism may be added to the link, and the swing of the link is converted into a linear reciprocating motion by the high-order mechanism, thereby driving the support body 2 to reciprocate along the linear motion.

The sensor 5 detects information about the displacement of the component fixed with respect to the drive shaft 32. The sensor 5 is, for example, an acceleration sensor. In the first embodiment, the bracket 10 is located between the connecting rod 40 and the driving body 30, the sensor 5 is fixed to the connecting rod 40, and the sensor 5 detects acceleration information related to the displacement of the connecting rod 40 fixed relative to the driving shaft 32. Alternatively, in a second embodiment as shown in fig. 3, the sensor 5 is fixed to a follower 42 fixed relative to the actuating shaft 32, the follower 42 being fixed to the actuating shaft 32 between the actuating body 30 and the support 10. The sensor 5 detects acceleration information related to the displacement of the follower 42 fixed relative to the drive shaft 32. The sensor 5 is located on the connecting rod 40 or on the follower 42 at a position offset from the axial center of the drive shaft 32 by an eccentricity greater than the maximum diameter of the drive shaft 32. Therefore, the linear velocity of the sensor 5 is greater than the linear velocity on the driving shaft 32, and the change of the displacement can be detected more sensitively than the case that the sensor 5 is directly fixed on the driving shaft 32, so that more accurate acceleration information can be obtained.

The two housings 8 are fixed to the tops of two brackets 10 of the support 1, respectively. At least one of the covers 8 covers the sensor 5 and the drive body 30 and provides protection for the driver 3 and the electrical and electronic components such as the wires 50. The two identical outer covers 8 provide a neat appearance without cluttering the appearance due to the arrangement of the driver 3 and the wires 50.

In a third embodiment shown in fig. 4, the drive housing 34 is made up of two halves with a receiving space 36 therein. The driver 3, the sensor 5, and the controller 6 are all mounted in the housing space of the drive housing 34, and only the drive shaft 32 extends from the drive housing 34 for outputting power. Therefore, the structure is compact, the appearance is simple, and even the outer cover 8 can be omitted. The sensor 5 is a hall sensor, a magnet 52 is mounted on the drive shaft 32 or the follower 42 fixed relative to the drive shaft 32, the drive body 30 and the sensor 5 are fixed to the drive housing 34, and the sensor 5 is located in the effective magnetic field of the magnet 52. When the driving shaft 32 is operated, the magnet 52 rotating with the driving shaft generates a changing magnetic field at the position of the sensor 5, and the sensor 5 detects the displacement of the driving shaft 32 according to the change of the rotating magnetic field sensed by the hall sensor. Thus, the sensor 5 detects acceleration information related to the displacement of the magnet 52 fixed relative to the drive shaft 32. The driver 3 includes a driving body 30 and a driving shaft 32, the driving body 30 is fixed in the accommodating space 36, the driver 3 has a driving state in which the driving shaft 32 outputs a reciprocating rotational power within an angular range of not more than 180 degrees and a passive state in which the driving shaft 32 is freely rotatable within the angular range with respect to the driving body 30. Those skilled in the art will appreciate that in alternative embodiments, the sensor 5 may be an acceleration sensor, similar to that shown in fig. 3, a follower 42 is fixed to the driving shaft 32, the sensor 5 is fixed to the follower 42 at a position offset from the axial center of the driving shaft 32, the eccentricity is greater than the maximum diameter of the driving shaft 32, and the controller 6 is electrically connected to the sensor 5 through a flexible wire 50.

The controller 6 is electrically connected to the driver 3 and to the sensor 5. In the first embodiment shown in fig. 1 and 2 and the second embodiment shown in fig. 3, the controller 6 and the sensor 5 are electrically connected by a flexible electric wire 50. In the third embodiment shown in fig. 4, the controller 6 and the sensor 5 are fixed in position and can be directly connected by a printed circuit without flexible wires. The controller 6 has a first operating mode and a second operating mode. In the first operation mode, the actuator 3 is in a passive state, the support body 2 can be shaken manually, and the controller 6 acquires information from the sensor 5 to calculate the operation width and frequency of the interlocking member 4. In the second mode of operation, the controller 6 controls the driver 3 to drive the drive shaft 32 in a periodic motion with an amplitude and frequency of operation. That is, in the first operation mode, the controller 6 stores the operation range and frequency of the artificial sway supporting body 2, and in the second operation mode, the controller 6 controls the actuator 3 to reproduce the operation range and frequency of the artificial sway, thereby automatically simulating the operation of the artificial sway and giving the infant artificial care.

Therefore, according to the technical scheme of the application, the device for caring for the baby can easily realize automatic and manual shaking, and the device for caring for the baby can realize artificial actions by automatic shaking, and has the advantages of simple structure and easy realization.

The above detailed description is merely illustrative of the present application and is not intended to be limiting. Various changes and modifications can be made by one skilled in the art without departing from the scope of the present application, and all equivalent technical solutions also belong to the scope of the present application, and the protection scope of the present application should be defined by the claims.
