Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202423323115.2, filed on Dec. 31, 2024, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present invention relates to the field of children's products, particularly to a bidirectional moving children's rocking frame.

BACKGROUND

A baby rocking bed, a type of crib designed to help babies fall asleep, can simulate the environment of a baby in the uterus and provide comfort to the baby through slight shaking, thereby reducing the caregiver's physical exertion.

The existing children's rocking frames generally comfort babies through shaft rotation, such as the Chinese patent CN202410549869.5, however, in actual use, it has a relatively single rocking direction. Therefore, it is necessary to design a step that imitates human walking to reduce baby discomfort and improve user experience.

SUMMARY

The main objective of the present invention is to propose a bidirectional moving children's rocking frame which aims to, through the cooperation of longitudinal and transverse frames, imitate the movement of human body based on the displacement of the frame, effectively improve the comfort of infants, and enhance the soothing effect with less manpower.

In order to achieve the above objectives, the present invention discloses a bidirectional moving children's rocking frame, comprising:

• • a base having a hollow cavity;
  • a longitudinal frame in the hollow cavity, wherein the longitudinal frame has a longitudinal seat, and the hollow cavity has a first driving device that drives the longitudinal seat to slide along a length direction of the longitudinal frame;
  • a transverse frame on the longitudinal seat, wherein the transverse frame has a transverse seat, and the longitudinal seat has a second driving device that drives the transverse seat to slide along a length direction of the transverse frame;
  • the longitudinal frame and the transverse frame are transversely arranged, and the longitudinal frame and the vertical frame are tangent at a right angle; and
  • a bracket that is disassembled from and installed on the transverse seat.

In practical design, the base, longitudinal frame, and transverse frame are all transversely arranged, therefore when the longitudinal seat and transverse seat move, the bracket moves along the longitudinal and transverse directions, and simulate the walking steps of the human body, and based on the combined movement of the first driving device and the second driving device, the size or frequency of the stroke can be adjusted to regulate the movement of the bracket.

Meanwhile, the detachable arrangement of bracket facilitates transportation and adjustment of tilt angle, making it suitable for different soft objects such as baby beds or baby seats.

The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, transverse, longitudinal, counterclockwise, clockwise, circumferential, radial, axial . . . ) in the embodiments of the present invention are only used to explain the relative position relationship and movement among various components in a particular posture (as shown in the accompanying drawings), and if that particular posture is changed, the directional indications will change accordingly.

In addition, descriptions involving terms “first,” “second” and the like, if any, in the present invention are only for illustrative purposes and cannot be understood as indicating or implying relative importance or the number of features referred to. Therefore, the features defined with “first” and “second” may explicitly or implicitly include at least one or a plurality of the features. At the same time, the technical solutions of various embodiments can be combined with each other, but must be based on what those of ordinary skill in the art can achieve. The combination of technical solutions that result in contradiction or make it impossible to implement should be considered non-existent, and accordingly should not fall within the scope of protection required by this present invention.
