[0034] This application is based on the fact that adults and children are prone to falling asleep in cars. We developed this baby care

[0035] The product can achieve three-dimensional movement, a combination of plane arc + vertical lifting movement, simulating the turning and bumpy movement of a car, creating a movement feeling similar to sitting in a car, so as to quickly coax the baby to sleep.

[0036] like Figure 1-7 As shown, the present invention discloses an infant care device, including a base 1 and a seat base 19, wherein a base cover 20 is connected to the base 1, a plane arc motion mechanism is provided between the base cover 20 and the base 1, and an output end of the plane arc motion mechanism is connected to a vertical lifting motion mechanism; the bottom end of the seat base 19 is connected to the output end of the vertical lifting motion mechanism, and the top end of the seat base 19 passes through the outside of the base cover 20 and is connected to a rocking chair frame device; the plane arc motion mechanism and the vertical lifting motion mechanism work to drive the rocking chair frame device to perform three-dimensional compound motion.

[0037] The present invention drives the rocking chair frame device at the output end of the vertical lifting motion mechanism to perform three-dimensional compound motion through the joint action of the plane arc motion mechanism and the vertical lifting motion mechanism. The rocking chair frame performing the three-dimensional compound motion can quickly coax the baby to sleep.

[0038] The baby care device designed by the present invention has a plane arc motion mechanism designed to perform arc-shaped reciprocating motion. Specifically, the plane arc motion mechanism includes a first drive assembly and a moving seat 7, the moving seat 7 is slidably connected to the base 1, and the first drive assembly and the moving seat 7 are connected to enable the moving seat 7 to perform arc-shaped reciprocating motion.

[0039] In order to enable the movable seat 7 to perform circular arc reciprocating motion on the base 1, the first driving component adopts an eccentric wheel design. Specifically, the first driving component includes a motor component 3 connected to the base 1 and a first large pulley 6 rotatably arranged on the base 1; the first small pulley 4 connected to the output end of the motor component 3 is connected to the first large pulley 6 through a first belt 5. An eccentric shaft is connected to the non-center portion of the first large pulley 6, which is rotatably connected to the right end of the movable seat 7 through the eccentric shaft.

[0040] like Figure 6 As shown, the present application also specially sets the following control component, a black and white reflective grid is screen-printed on the back of the first large pulley 6 (the side close to the base 1), and a sensor 30 is set on the base 1 below the first large pulley 6. The sensor can detect the reflective grid. The sensor 30 identifies the rotation speed and relative position of the pulley by detecting the grid to accurately control the trajectory of the moving seat 7. Through the setting of this control component, accurate intelligent control of the moving seat 7 can be achieved.

[0041] In some further embodiments, a cylindrical boss 29 is provided at the bottom of the left end of the movable seat 7. The cylindrical boss 29 is slidably connected to the long groove of the base and can rotate relatively, so that the movable seat 7 reciprocates in an elliptical arc on the base 1.

[0042] During operation, the motor assembly 3 works, and drives the first large pulley 6 to rotate through the first small pulley 4 and the first belt 5. The rotation of the first large pulley 6 drives the eccentric shaft connected thereto to make a circular motion around the center of the first large pulley 6. Since the eccentric shaft is connected to the right end of the movable seat 7, the rotation of the first large pulley 6 can drive the movable seat 7 to realize an arc reciprocating motion.

[0043] In a further embodiment of the present application, in order to ensure the moving effect of the moving seat 7, a universal wheel 8 and a moving rotating wheel 9 are arranged on the bottom surface of the moving seat 7, the universal wheel 8 is arranged at the right end of the bottom surface of the moving seat 7, and the moving rotating wheel 9 is arranged at the left end of the bottom surface of the moving seat. By arranging the moving rotating wheel 9 and the universal wheel 8, the movement stability and convenience of the moving seat 7 can be ensured.

[0044] In a further embodiment of the application, the vertical lifting mechanism includes a lifting support seat 16 connected to the moving seat 7, and a lifting slide seat 15 is slidably connected in the lifting support seat 16; the bottom end of the seat seat 19 is connected to the lifting slide seat 15. When working, the lifting slide seat 15 is lifted and lowered to drive the seat seat 19 to lift and lower.

[0045] Furthermore, in order to ensure that three-dimensional composite motion can be completed between the base 1 and the base cover 20, the present application adopts an eccentric motion mechanism plus a screw-nut mechanism, that is, the lifting and lowering of the lifting sliding seat 15 is achieved through the screw-nut mechanism.

[0046] In a specific embodiment, the vertical lifting motion mechanism also includes a screw rod 13 and a lifting drive motor assembly 10 connected to the moving seat 7. The bottom end of the screw rod 13 passes through the bottom of the moving seat 7 and is fixedly connected to the central axis hole of the second pulley 12. The outer periphery of the screw rod 13 located above the moving seat 7 is threadedly connected with a screw nut 14, and the screw nut 14 is fixedly connected to the lifting sliding seat 15.

[0047] The pulley at the output end of the lifting drive motor assembly 10 is connected to the second pulley 12 through the second belt 11. When working, the lifting drive motor assembly 10 works, drives the second pulley 12 to rotate, the screw rod 13 in the second pulley 12 rotates, and the screw rod nut 14 connected to the screw rod 13 moves up and down, driving the lifting slide seat 15 to move up and down.

[0048] Furthermore, if Figure 3As shown, a protruding connection seat is provided on the movable seat 7, and the lifting support seat 16 is roughly L-shaped, and its vertical part is hollow, which is sleeved on the protruding connection seat and fixed by screws.

[0049] In some further embodiments, in order to ensure the lifting and sliding effect of the lifting and sliding seat 15, two guide pillars 17 are further provided in the lifting support seat 16, the top ends of the guide pillars 17 are connected to the horizontal part of the lifting support seat 16, and the bottom ends are inserted into the holes of the moving seat 7. The lifting and sliding seat 15 is provided with through holes, and the guide pillars 17 are slidably connected to the through holes.

[0050] like Figure 5 As shown, the present application also deliberately sets the following control components, a sensing boss 15-1 is set on the side of the lifting sliding seat 15, an infrared sensor 31 is set on the side of the horizontal part of the lifting support seat 16, and an infrared sensor 31 is set on the moving seat 7, and the two infrared sensors 31 are respectively located on the upper and lower sides of the lifting sliding seat 15. When the lifting sliding seat moves upward, the sensing boss 15-1 moves and contacts the upper infrared sensor 31, and the upper infrared sensor 31 transmits a signal to the lifting drive motor assembly 10 to control the lifting drive motor assembly 10 to rotate in the opposite direction, and then controls the screw rod to rotate in the opposite direction to realize the downward movement of the lifting sliding seat 15. When the sensing boss 15 on the lifting sliding seat 15 moves to contact the lower infrared sensor 31, the lower infrared sensor 31 transmits a signal to the lifting drive motor assembly 10 to control the lifting drive motor assembly 10 to rotate in the opposite direction to realize the upward movement of the lifting sliding seat 15. This setting ensures that the lifting sliding seat 15 can automatically reverse after moving to the upper and lower limit positions.

[0051] In some further embodiments, the top of the lifting support seat 16 is further connected with a movable baffle 18 by screws, and the size of the movable baffle 18 is larger than the size of the hole on the base cover 20. When the plane arc motion mechanism drives the lifting support seat 16 to perform elliptical arc reciprocating motion, the movable baffle 18 can still block the hole on the base cover 20 to ensure the sealing effect.

[0052] In some embodiments, the rocking chair frame device includes a rocking chair support seat 22 connected to the top of the seat seat 19, and both ends of the top of the rocking chair support seat 22 are connected to seat joints 28, one side of the two seat joints 28 is connected to a seat rod 26, and the other side is connected to a backrest rod 27. The bottom of the rocking chair support seat 22 is connected to a rocking tube 25.

[0053] When the rocking chair frame device is removed from the seat holder 19, the rocking tube 25 is used to provide support, and the rocking chair frame device can be placed on the ground through the rocking tube 25. The seat rod 26 and the backrest rod 27 provide protection and support for the baby.

[0054] In some further embodiments, a control panel 21 is also provided on the base cover 20, and the control panel 21 is connected to an internal controller or a PCB circuit board. The controller or the PCB circuit board is used to control the movement of the lifting drive motor assembly 10 and the motor assembly 3 to realize three-dimensional compound movement of the device.

[0055] In some further embodiments, the present application further designs a quick folding button 23 and a rocking chair rotation locking button 24. The quick folding button 23 is used for folding the rocking chair frame device, and the rocking chair rotation locking button 24 is used for locking the rocking chair frame device to prevent it from rotating.
