However, as shown in FIG. 5, the left and right width adjusting portions 16 may be formed in the form of a sliding rail, . When the body 1 is divided into a front frame 12 and a rear frame 13, the left and right width adjusting portions 16 may be formed in any one of the front frame 12 and the rear frame 13 And is formed between the frames positioned outward of them, so as not to be influenced by the body 1 sliding according to the size of the baby carriage wheel W.

The sliding frame 162 is formed on the other side of the body 1 and is inserted into the fixed frame 161 and slidably engaged with the fixed frame 161 to be slid in a rail shape. The sliding frame 162 may include a first sliding frame 162a and a second sliding frame 162b which can be slid to the left and right so that the length in which the left and right width adjusting portions 16 can be extended can be made longer . A sliding ball 163 is inserted between the sliding frame 162 and the fixed frame 161 so that the fixed frame 161 and the sliding frame 162 are smoothly inserted It can be slid.

The first sliding frame 162a and the second sliding frame 162b are slidably engaged with each other as described with respect to the fixed frame 161 and the sliding frame 162. The length of the left / . A sliding ball 163 may be inserted between the first sliding frame 162a and the second sliding frame 162b and may be inserted into any one of the first sliding frame 162a and the second sliding frame 162b A plurality of locking protrusions 162c may be formed so that the sliding balls 163 are caught and fixed.

In the state in which the first sliding frame 151a is released from the fixed frame 161, The second sliding frame 162b is slid out from the first sliding frame 162a and the sliding ball 163 is also engaged with the first sliding frame 162a or the second sliding frame 162b, And is fixed to the position corresponding to D2. Therefore, the right and left widths between the bodies 1 can be kept constant while the automatic reciprocating waving device for the wheeled child-care apparatus is reciprocating.

The wheel 2 is formed in the body 1 and rotates, and is preferably formed in a circular shape. However, the wheel 2 is formed in a shape having an angular shape or a protrusion, so that when the body 1 reciprocates, It is also possible to make it happen. The wheels 2 are preferably formed on both sides of the body 1, but the present invention is not limited thereto. The wheels 2 may be formed in various numbers at various positions such as the bottom center of the body 1. The wheels 2 are preferably formed on the front frame 12 and the rear frame 13 so that the body 1 can reciprocate stably. The wheel 2 is connected to a rotary shaft 21 that receives the driving force of the driving unit 3 and rotates and reciprocates forward and backward according to the driving force of the driving unit 3.

The driving unit 3 provides a driving force for reciprocating the body 1, and rotates the rotating shaft 21. The driving unit 3 may be an AC or DC motor, and various power units capable of rotating the rotary shaft 21 may be used. The drive unit 3 is connected to the battery 4 to receive electrical energy and a power transmission unit 5 to be described later is formed between the rotation shaft 21 and the drive unit 3, Thereby reducing consumption. In addition, the driving unit 3 is controlled by the controller 6 so that the body 1 alternately moves in the forward and backward directions and alternately rotates so as to reciprocate.

The battery 4 is connected to the driving unit 3 to supply power, and various types of power supply means can be applied, and the battery 4 can be charged or replaced. Further, since the consumption of the battery 4 is minimized by the power transmission unit 5 to be described later, it is possible to configure the battery 4 to be small in size, thereby making it possible to reduce the weight and size of the automatic reciprocating and swinging device for the wheel- .

The power transmitting portion 5 is formed between the driving portion 3 and the rotary shaft 21 to transmit and control the driving force of the driving portion 3 so that a separate braking device such as a brake is not required, Energy can be stored to minimize energy consumption, that is, power. The power transmitting portion 5 includes a driving gear 51, a braking gear 52, a moving gear 55, an elastic member 53, a connecting member 54, a rotating member 56, And the like. The power transmission unit 5 may be formed by a belt connected to a pulley, or a chain connected to a sprocket, in addition to a system using gears.

The driving gear 51 is connected to the driving unit 3 and rotates together to transmit the driving force of the driving unit 3. The driving gear 51 is connected to the driving unit 3 through various gears such as an idle gear I, (3) is transmitted. The driving gear 51 has a central hollow to allow the rotation shaft 21 to pass therethrough. When the moving gear 55 rotating together with the rotation shaft 21 moves and engages with the driving gear 51, The moving gear 55 rotates together with the rotation of the driving gear 51 so that the rotating shaft 21 also rotates. Therefore, the driving gear 51 forms a protrusion 511 along the periphery on the surface facing the moving gear 55 so as to engage with the protrusion 551 formed on the moving gear 55 and rotate .

The braking gear 52 is engaged with the moving gear 55 when the wheel 2 is braked and an elastic member 53 is connected to one side of the braking gear 52 to rotate the braking gear 52 So as to stop the rotation of the moving gear 55 and to stop the rotation of the wheel 2. The braking gear 52 is formed with a hollow at its center as the driving gear 51 and allows the rotation shaft to pass therethrough. The braking gear 52 has a protrusion 521 formed on a surface thereof facing the moving gear 55, So as to be rotatable. The braking gear 52 includes a reduction groove 522 formed in a predetermined depth along the circumferential surface so that the connection member 54 connected to the elastic member 53 or the elastic member 53 is wound. can do.

The damper groove 522 has a configuration in which the connecting member 54 connected to the elastic member 53 or the elastic member 53 is wound and the pulley and the chain The elastic member 53 or the connecting member 54 wound around the brake gear 52 including the reduction groove 522 may be wound constantly It is desirable to be able to be loosened. The end of the elastic member 53 or the linking member 54 is fixed to the reduction groove 522 so that the braking gear 52 is engaged with the moving gear 55 to rotate the elastic member 53 The connecting member 54 connected to the elastic member 53 or the elastic member 53 is wound along the winding groove 522 and the braking gear 52 and the moving gear 55 The connecting member 54 is released from the reduction groove 522 by the restoring force of the elastic member 53 and the braking gear 52 and the moving gear 52 are rotated by the restoring force of the elastic member 53, 55 are engaged with each other and rotate in the direction opposite to the original direction. Accordingly, the moving gear 55 rotates the rotating shaft 21 while rotating in a state of having a rotating force of the opposite eccentricity due to the restoring force of the elastic member 53. Therefore, when the moving gear 55 moves again and engages with the driving gear 51, the driving force can be reduced by the rotational force obtained by the restoring force of the elastic member 53, so that power consumption can be minimized, Since the above process is continuously repeated, the consumed power is much smaller than when the elastic member 53 is absent.

The elastic member 53 is connected to the braking gear 52 and is configured to decelerate the rotation of the braking gear 52 by a resilient restoring force. The elastic member 53 has one end connected to the body 1 or the power transmitting portion 5 And the other end thereof is connected to the braking gear 52 or the connecting member 54. [ The elastic member 53 may be wound around the spiral groove 522 as described above but may be connected to a separate connecting member 54 so that the connecting member 54 is wound on the spiral groove 522 So that the elastic member 53 is not twisted or the elasticity is reduced. Therefore, the elastic member 53 is rotated by the resilient restoring force to decelerate the rotation of the braking gear 52, so that the connecting member 54 is wound on the reduction groove 522, It is possible to reduce the energy and power consumed in the opposite direction rotation by causing the rotation of the rotation shaft 52 to rotate in the opposite direction at the same time as stopping.

The connecting member 54 is connected to the elastic member 53 at one end and the other end is fixed to the reducing groove 522, and a steel cord or the like is preferably applied. Therefore, when the braking gear 52 rotates in the opposite direction, the connecting member 54 is wound on the reducing groove 522 in accordance with the rotation of the braking gear 52, At this time, it is possible to prevent a problem such as twisting or breaking of the line. However, the connecting member 54 is not limited thereto. When the braking gear 52 has a form of a pulley, it may be formed of a belt or a sprocket if it has a chain, and the elastic member 53 And the braking gear 52, so that the displacement amount of the spring can be reduced by the gear ratio.

The moving gear 55 moves between the driving gear 51 and the braking gear 52 and rotates together with the rotating shaft 21. The moving gear 55 is provided with a projection 211 in the form of a spline with the rotating shaft 21, that is, around the rotating shaft 21, A groove having a corresponding shape is formed so as to be able to fit together. In addition, the center portion of the moving gear 55 may be configured to have a shape corresponding to the rotation axis 21 of an angular shape such as a quadrangle, a hexagon, an octagon, etc., and not rotate in a spline shape. The moving gear 55 includes an insertion groove 553 formed to be embedded along the circumference of the rotary gear 56 so that the rotary member 56 can be inserted. So that the moving gear 55 can be moved toward the driving gear 51 side and the braking gear 65 side.

The rotating member 56 is configured to rotate left and right by a predetermined angle in a state of being inserted into the insertion groove 553 and the moving gear 55 moves left and right according to the rotation of the rotating member 56 The drive gear 51 and the brake gear 65 can be engaged with each other. The rotary member 56 is preferably formed of a plate member having a predetermined length and is formed in a circular shape and inserted into the insertion groove 553 and the other end is connected to the rotary shaft 571 And serves as the center of rotation of the rotary member 56. [

The rotation driving means 57 may be a step motor connected to the other end of the rotary member 56 to rotate the rotary member 56 and rotate the rotary member 56 at a predetermined angle to both sides, It is not.

12 (a) is a view showing a state in which a driving force is transmitted to the driving gear 51 by the driving unit 3 (see FIG. 12) The driving gear 51 rotates in conjunction with the driving unit 3 and the driving gear 51 is engaged with the moving gear 55 and rotates together with the driving gear 51, The rotating shaft 21 also rotates together. Accordingly, the wheel 2 connected to the rotary shaft 21 receives the driving force of the driving unit 3 and rotates to move the body 1. Next, the moving gear 55 is moved toward the braking gear 52 in accordance with the rotation of the rotating member 56 by the rotation driving means 57, and the moving gear 55 is moved to the side of the braking gear 52 , The braking gear 52 rotates together with the moving gear 55. At this time, the braking gear 52 is rotated in the same direction as the braking gear 52, The connecting member 54 connected to the elastic member 53 is rotated by the restoring force of the connected elastic member 53 while the rotational speed of the braking gear 52 and the moving gear 55 is reduced, And is wound around the winding groove 522. The rotation speed of the braking gear 52 and the moving gear 55 is reduced to stop the rotation and at the same time the braking gear 52 and the moving gear 55, The connecting member 54 starts to rotate in the opposite direction due to the restoring force of the spring 53, and the connecting member 54 is released from the reducing groove 522. [ 12 (d), the moving gear 55 moves toward the driving gear 51 side by the rotating member 56 while rotating in the opposite direction, When it is engaged with the gear 51, a rotational force in the opposite direction is additionally obtained from the driving unit 3 and continues to rotate in the opposite direction. Accordingly, it is possible to automatically perform the reciprocating motion of the child care apparatus while repeating the above-described process, thereby saving the energy consumed. For example, the driving gear, the moving gear, the braking gear, and the like are formed on the rotating shaft 21 of the wheel 2 so as to intermittently transmit power. However, the present invention is not limited thereto, So that the changed power can be transmitted to the rotary shaft 21. [0064]

In addition, the moving gear 55 may include a first moving gear 554 and a second moving gear 555 as shown in FIG. 13 in another embodiment. The first moving gear 554 and the second moving gear 554 have the same structure in which the protrusion 551 is formed only on one side and the insertion groove 553 is formed. (52). At this time, the rotary member 56 and the rotary drive unit 57 may also be formed to be connected to the first moving gear 554 and the second moving gear 554, respectively. The braking gear 52 is controlled by the elastic member 53 differently from the case where only one moving gear 55 is formed by controlling the first moving gear 554 and the second moving gear 554, So that the reverse rotation of the elastic member 53 or the coupling member 53 can be further obtained by the driving gear 51 before the rotation of the elastic member 53 by the restoring force is stopped, So that the power consumed by the reverse rotation force obtained by winding the braking gear 54 around the braking gear 52 can be more efficiently reduced. In other words, the second moving gear 555 is engaged with the braking gear 52 and is rotated by the elastic member 53 while the elastic member 53 or the connecting member 54 is engaged with the braking gear 52 52 and the rotational force is accumulated. The braking gear 52 and the moving gear 55 are rotated in opposite directions as the elastic member 53 or the connecting member 54 begins to be released and the reverse rotation due to the restoring force of the elastic member 53 is stopped The first moving gear 553 is connected to the driving gear 551 to minimize the power consumed by the driving unit 3 by obtaining a rotational force in the opposite direction from the driving unit 3.

14, the power transmission unit 5 includes a cam drive unit 58 instead of the rotation member 56, and even if only one rotation drive unit 57 is used, The reverse rotation force of the driving gear 51 can be transmitted to the rotation shaft 21 before the reverse rotation of the braking gear 52 due to the restoring force of the elastic member 53 is completed. In other words, while the second shifting gear 555 and the braking gear 52 are engaged with each other and are reversely rotated by the restoring force of the elastic member 53, the first shifting gear 554 is rotated And the driving gear 51 is rotated in the reverse direction by the driving unit 3 to minimize the power consumed by the driving unit 3. The cam driving unit 58 includes a cam driving gear 581 connected to the rotation driving unit 57 by a connecting gear 572 and rotated together therewith; A timing cam 582 formed on the cam driving gear 581 and rotated together with the cam driving gear 581; The center is fixed, one side moves along the circumferential contour of the timing cam 582, and the other side includes an operating lever 583 connected to the first moving gear 554 or the second moving gear 555 . The cam drive unit 58 is formed on both sides of one rotation drive unit 57 and is connected to the first and second moving gears 554 and 555, respectively. The cam driving unit 58 connected to the first moving gear 554 is referred to as a first cam driving unit 58-1 and the cam driving unit 58 connected to the second moving gear 555 is referred to as a second cam driving unit 58 -2), and the first cam driver 58-1 and the second cam driver 58-2 have the same structure, but the first and second moving gears 554, Only the point at which the timing cam 582 and the operation lever 583 are brought into close contact with each other may be changed so that the timing at which the timing cam 58 and the brake lever 52 are engaged with each other may be different.

The cam driving gear 581 is connected to both sides of the cam driving gear 581 by a connecting gear 572 which rotates together with the rotational shaft 571 of the rotational driving means 57 via the rotational driving means 57, And the cam drive gears 581 on both sides engage with the connecting gear 572 and rotate together.

The timing cam 582 is formed on the cam driving gear 581 and rotates together so that one side of the operating lever 583 moves along the circumferential contour. As shown in FIG. 14, 360 ° is divided into a 120 ° portion and a 240 ° portion so as to be formed into a circle having a different radius, and when the operating lever 583 is rotated by the first cam driver 58-1 in FIG. 14, The first moving gear 554 is pushed to the driving gear 51 side by the operating lever 583 when the timing cam 582 is in contact with a long portion of the timing cam 582, 583 are brought into contact with a short radius of the timing cam 582 like the second cam driver 58-2 of Fig. 14, the second moving gear 555 is moved by the operating lever 583 So as to be pushed toward the brake gear 52 side. Therefore, the first moving gear 554 and the second moving gear 555 can be periodically engaged with the driving gear 51 and the braking gear 52, respectively, in accordance with the rotation of the rotation driving means 57 And the necessary operation timing can be adjusted by changing the angles of the short and long portions of the timing cam 582. [ Further, by adjusting the rotation speed of the rotation driving means 57 for each section, the coupling time with the driving gear 51 and the braking gear 52 can be adjusted.

The center of the operation lever 583 is fixed so that the side of the timing cam 582 and the side of the drive gear 51 or the braking gear 52 move in opposite directions to each other, The drive gear 51 or the braking gear 52 may be engaged with the long side of the radius of the timing cam 582. When the drive gear 51 or the braking gear 52 is in close contact with the short side of the radius of the timing cam 582, 52).

Referring to Fig. 15, the operation of the power transmitting portion 5 via the cam driving portion 58 will be described. As shown in Fig. 15 (a), the operation of the first cam driving portion 58-1 The lever 583-1 contacts the long side of the timing cam 582-1 to move the first moving gear 554 to engage with the driving gear 51 and then the driving gear 51 Is rotated by the driving unit 3, the rotating shaft 21 is rotated together with the first moving gear 554. [ At this time, the operating lever 583-2 of the second cam driving part 58-2 is brought into contact with the short side of the radius of the timing cam 582-2 so that the second moving gear 555 contacts the brake gear 52, So as to be in a state in which it is not engaged. When the rotational speed of the rotating shaft 21 reaches a predetermined speed, as shown in FIG. 15 (b), in accordance with the rotation of the rotational driving means 57, the operating lever of the first cam driving portion 58-1 The first cam gear 583-1 is brought into contact with the short side of the timing cam 582-1 so that the first gear 554 is moved away from the driving gear 51, The operating lever 583-2 of the cam driving section 58-2 is brought into contact with the long side of the timing cam 582-1 so that the second moving gear 555 is engaged with the brake gear 52 The braking gear 52 and the second moving gear 555 are moved in the opposite direction by the restoring force of the elastic member 53 as described above so that the rotating shaft 21 is stopped by the braking gear 52, Direction. 15 (c), in the state in which the rotating shaft 21 rotates in the opposite direction together with the braking gear 52 and the second moving gear 555, the rotation driving means 57, The operation lever 583-1 of the first cam driver 58-1 continues to rotate in the same direction so that the timing cam 582-1 comes into contact with the longer side of the radius of the timing cam 582-1, The moving gear 554 meshes with the driving gear 51 and receives a rotational force in the opposite direction from the driving unit 3. Therefore, as described above, before the reverse rotation due to the restoring force of the elastic member 53 is stopped, the rotating shaft 21 receives the rotational force of the driving gear 51 to thereby reduce the power consumed by the driving unit 3 Can be minimized. 15 (d), when the restoring force by the elastic member 53 is completed, the operating lever 583-2 of the second cam driving portion 58-2 is rotated by the timing cam 582-2 So that the second moving gear 555 is moved away from the braking gear 52. As shown in Fig. Then, the baby carriage such as a baby carriage can be reciprocated by continuing the cyclic reciprocating motion as described above.

The sound sensor 64 is attached to a part of the body 1 to recognize a sound. A signal measured by the sound sensor 64 is transmitted to the controller 7. When the intensity of the sound measured by the sound sensor 64 is equal to or greater than a predetermined value, the movement of the body 1 can be started, or the frequency of the sound can be measured, May be configured to move.
