Description

Technical Field

[0001] This utility model relates to the field of children's products, and in particular to an infant cradle. Background Technology

[0002] Most existing baby rockers require manual pushing to achieve a continuous rocking function, which is very important for young babies as it effectively prevents them from crying. However, for adults, the time and energy required to continuously rock a baby rocker is too high. If an automatic baby rocker could be developed, it would meet the baby's needs while giving adults more personal time.

[0003] Existing automatic rocking chairs have relatively simple structures. Referring to patent 201720157425.2, they mainly achieve the rocking function by driving the rocking seat to move back and forth and causing the net bag in the top rocking chair assembly to rock. However, this rocking structure is relatively simple and cannot completely imitate the swinging method of a traditional rocking chair. Therefore, there is a need for a baby cradle that can move in both horizontal and vertical directions, can imitate the swinging method of a traditional rocking chair, and can provide a better user experience for babies. Utility Model Content

[0004] The main purpose of this invention is to provide a baby cradle that can move in both the horizontal and vertical directions, mimics the swaying motion of a traditional rocking chair, and provides a better user experience for infants.

[0005] This utility model proposes an infant cradle, including a base, a horizontal movement seat, a horizontal movement mechanism, a vertical movement seat, a vertical movement mechanism, and a rocking chair assembly;

[0006] The horizontal motion seat is slidably connected to the base, and the horizontal motion mechanism is disposed in the base. The horizontal motion mechanism drives the horizontal motion seat to move repeatedly in the base.

[0007] The vertical motion seat and the vertical motion mechanism are mounted on the horizontal motion seat. The vertical motion mechanism drives the vertical motion seat to move repeatedly on the horizontal motion seat. The rocking chair assembly is fixedly connected to the top of the vertical motion seat.

[0008] By cooperating with the horizontal and vertical motion seats, the rocking chair assembly can be driven to move in a manner that mimics the motion trajectory of a normal rocking chair.
