[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Embodiment 1

[0019] Combination Figures 1 to 8 The present embodiment provides a child cradle, comprising a controller, an X-axis motion mechanism 1, a Y-axis motion mechanism 2, a Z-axis motion mechanism 3 and a cradle body 4. The X-axis motion mechanism 1 and the Y-axis motion mechanism 2 are respectively connected to the Z-axis motion mechanism 3. In some embodiments, the X-axis motion mechanism 1 and the Y-axis motion mechanism 2 are respectively mounted on the same mounting plate 7; the cradle body 4 is fixedly connected to the Z-axis motion mechanism 3, and the Z-axis motion mechanism 3 controls the cradle body 4 to move up and down along the Z-axis straight line. Further, in some embodiments, a rolling member 5 is provided on the Z-axis motion mechanism 3, and the rolling member 5 is used to support the Z-axis motion mechanism 3 above the mounting plate 7.

[0020] The X-axis motion mechanism 1 and the Y-axis motion mechanism 2 are connected to the Z-axis motion mechanism 3, respectively. The controller drives the X-axis motion mechanism 1 to move, so that the Z-axis motion mechanism 3 and the cradle body 4 perform linear reciprocating motion along the X-axis direction. And / or, the controller drives the Y-axis motion mechanism 2 to move, so that the Z-axis motion mechanism 3 and the cradle body 4 perform linear reciprocating motion along the Y-axis direction. And / or, the controller drives the Z-axis motion mechanism 3 to move, driving the cradle body 4 to perform linear reciprocating motion along the Z-axis direction.

[0021] like Figure 1 and Figure 2The child cradle in this embodiment also includes two groups of elastic reset members 6; one group of elastic reset members 6 is always slidably connected to the Z-axis motion mechanism 3, and is installed on the mounting plate 7 in a relatively matched manner with the X-axis motion mechanism 1. The elastic reset member 6 is used to assist the X-axis motion mechanism 1 in driving the Z-axis motion mechanism 3 to reciprocate safely and stably along the X-axis straight line. The other group of elastic reset members 6 is always slidably connected to the Z-axis motion mechanism 3, and is installed on the mounting plate 7 in a relatively matched manner with the Y-axis motion mechanism 2. The elastic reset member 6 is used to assist the Y-axis motion mechanism 2 in driving the Z-axis motion mechanism 3 to reciprocate safely and stably along the Y-axis straight line. The two elastic reset members 6 are used to ensure the safety and stability of the Z-axis motion mechanism 3 and the cradle body 4 in the horizontal direction. The purpose of the elastic reset members 6 is to reduce the impact force of the linear motion, so that the cradle body 4 can move safely and smoothly during the entire motion process.

[0022] Specific, combined Figure 8 The elastic reset member 6 includes a fixing frame 61, a spring 62 and a support member 63. The fixing frame 61 includes a connecting rod, a top plate 64 and a bottom plate 65. The top plate 64 is fixedly connected to the top of the connecting rod, and the bottom plate 65 is arranged at the bottom of the connecting rod. The bottom end of the spring 62 is fixedly connected to the bottom plate 65 of the fixing frame 61. The rear end of the support member 63 is fixedly connected to the top of the spring 62, and the front end passes through the top plate 64 and is always slidably connected to the Z-axis motion mechanism 3. In some embodiments, the rear end of the support rod is mounted on a cross plate, and the cross plate is fixedly connected to the top of the spring 62.

[0023] In some embodiments, Figure 3 , Figure 4 and Figure 5 , the Z-axis motion mechanism 3 includes an installation box 31 and a first drive assembly 32. The installation box 31 is directly in contact with the installation plate 7 through the rolling element 5. The first drive assembly 32 is installed in the installation box 31, and the connecting shaft of the cradle body 4 passes through the installation box 31 and is fixedly connected to the first drive assembly 32. A front slide 33 is provided in the horizontal direction on the upper edge of the front side plate of the installation box 31; a rear slide 34 is provided in the horizontal direction on the upper edge of the rear side plate of the installation box 31; a left slide 35 is provided in the horizontal direction on the upper edge of the left side plate of the installation box 31; and a right slide 36 is provided in the horizontal direction on the upper edge of the right side plate of the installation box 31. The front end of the support member 63 of one elastic reset member 6 is slidably connected in the left slide 35, and the front end of the support member 63 of the other elastic reset member 6 is slidably connected in the rear slide 34. In some embodiments, the rolling element 5 includes a ball 51 and a bearing seat 52, and the bearing seat 52 is fixed to the bottom of the installation box 31. A part of the ball 51 is partially rolled and nested in the bearing seat 52, and the other part is against the installation plate 7.

[0024] In some embodiments, in combination with Figure 5 , Figure 6 and Figure 7The first driving assembly 32 includes a first crank 321, a second crank 322, a pushing frame 323, a driving device 324, a first gear 327, a second gear 328 and a fixed seat 325. The fixed seat 325 is installed on the installation box 31, and the driving device 324 is arranged on the fixed seat 325. The guide rod 326 is arranged on the fixed seat 325. The pushing frame 323 is slidably connected to the guide rod 326. The first gear 327 and the second gear 328 are always meshed. In this embodiment, the distance between the axle of the first gear 327 and the second gear 328 is limited by the retaining frame 329, so that the first gear 327 and the second gear 328 are always in meshing state. Specifically, when the first gear 327 and the second gear 328 are in meshing state, one end of the retaining frame 329 is fixed on the axle of the first gear 327, and the other end is fixed on the axle of the second gear 328.

[0025] The front end of the first crank 321 is fixedly connected to the axle of the first gear 327, and the rear end is fixedly connected to the shaft of the driving device 324. The front end of the second crank 322 is fixedly connected to the axle of the second gear 328, and the rear end is rotatably connected to the push frame 323 by a rotating shaft. The push frame 323 is fixedly connected to the connecting shaft of the cradle body 4. When the driving device 324 rotates, the first crank 321 rotates, and the first gear 327 connected to the front end of the first crank 321 performs a circular motion. Similarly, the meshing second gear 328 also performs a circular motion under the drive of the first gear 327. In this motion state, the push frame 323 slides linearly forward and backward along the push frame 323. The first driving assembly 32 acts on the cradle body 4 to reciprocate linearly along the Z-axis direction, so that the cradle body 4 rises or falls.

[0026] Optionally, the X-axis motion mechanism 1 includes a second drive assembly 11, which has the same structure and components as the first drive assembly 32. The connecting portion of the push frame 323 in the second drive member is slidably limited in the right slide groove 36 of the installation box 31.

[0027] Optionally, the Y-axis motion mechanism 2 includes a third drive assembly 21, and the second drive assembly 11 is selected to have the same assembly structure as the first drive assembly 32. The connection portion of the push frame 323 in the third drive assembly 21 is slidably limited in the front slide slot 33 of the installation box 31.

[0028] In summary, in the installation and connection mode, during the synchronous movement of the three motion mechanisms, the motion working principles of each motion mechanism and the cradle body 4 are as follows: When the second driving assembly 11 in the X-axis motion mechanism 1 drives the Z-axis motion mechanism 3 and the cradle body 4 to move forward in a straight line along the X-axis direction, the relative elastic reset member 6 cooperates to provide elastic support for the Z-axis motion mechanism 3, preventing the second driving assembly 11 from pushing the Z-axis motion mechanism 3 to generate a large impact force, so that the Z-axis motion mechanism 3 and the cradle body 4 can operate smoothly and stably. During this period, the third driving assembly 21 of the Z-axis motion mechanism 3 and the Y-axis motion mechanism 2 and the elastic reset member 6 that cooperates with them produce relative displacement, and the third driving assembly 21 in the Y-axis motion mechanism 2 drives the Z-axis motion mechanism 3 to move forward in a straight line along the Y-axis direction, and the elastic reset member 6 that cooperates with them mitigates the impact force of the Z-axis motion mechanism 3 in the Y-axis direction.

[0029] The second driving assembly 11 in the X-axis motion mechanism 1 drives the Z-axis motion mechanism 3 and the cradle body 4 to retreat and reset in a straight line along the X-axis direction, and the matching elastic reset member 6 assists in pushing the Z-axis motion mechanism 3 to reset. At the same time, the third driving assembly 21 in the Y-axis motion mechanism 2 drives the Z-axis motion mechanism 3 to retreat and reset along the Y-axis direction. The X-axis motion mechanism 1 and the Y-axis motion mechanism 2 simultaneously apply forces in two directions to the Z-axis motion mechanism 3, so that the X-axis motion mechanism 1 and the Y-axis motion mechanism 2 realize two motion trajectories: (i) at the same time and at the same frequency, the Z-axis motion mechanism 3 can make a circular motion in one reciprocating motion; (ii) at the same time and at different frequencies, the Z-axis motion mechanism 3 can make a movement of an elliptical trajectory in one reciprocating motion.

[0030] The first drive assembly 32 of the Z-axis motion mechanism 3 reciprocates linearly along the Z-axis direction, with the second drive assembly 11 or the third drive assembly 21 at the same frequency or at different frequencies. The cradle body 4 can produce a variety of trajectory motions, and can obtain a variety of rocking methods for coaxing a baby to sleep. Embodiment 2

[0031] This embodiment provides a method for controlling a child cradle, which is implemented by using any of the child cradles described in the first embodiment. The control method of the child cradle includes: The controller is set to control the movement of the X-axis motion mechanism 1 and / or the Y-axis motion mechanism 2 and / or the Z-axis motion mechanism 3, so that the cradle body 4 moves along the X-axis linear motion and / or the Y-axis linear motion and / or the Z-axis linear motion. Various combined motion forms in the horizontal direction and the vertical direction can be realized.

[0032] During the above-mentioned control motion mode, the controller can be selected to control the X-axis motion mechanism 1, the Y-axis motion mechanism 2 and the Z-axis motion mechanism 3 to move simultaneously, and the movements can be synchronous or non-synchronous. Alternatively, when the controller is set to drive any two of the three motion mechanisms, the X-axis motion mechanism 1, the Y-axis motion mechanism 2 and the Z-axis motion mechanism 3, to move simultaneously, and the motions are co-frequency or non-co-frequency. Combined with the co-frequency or non-co-frequency control, the X-axis motion mechanism 1, the Y-axis motion mechanism 2 and the Z-axis motion mechanism 3 act on the cradle body 4, achieving several different rocking experiences.

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
