The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 4, the baby rocking chair of the present embodiment includes:

a recliner frame 100, the recliner frame 100 having an X-direction 102 and a Y-direction 101 perpendicular to each other, and having a first side 103 and a second side 104 opposite in the X-direction 102;

a base 300, the base 300 having opposing mounting sides 301 and extension sides 302, wherein the mounting side 301 is located below the first side 103 of the recliner frame 100 and the extension sides 302 extend below the second side 104 of the recliner frame 100;

one end of the swing arm 200 is in rotating fit with the mounting side 301 of the base 300 around a first axis 205, the other end of the swing arm 200 is forked to form two supporting parts 201, and the two supporting parts 201 are respectively connected with two opposite sides of the recliner chair frame 100 in the Y direction 101;

a rotary joint 400, the rotary joint 400 is arranged at the connecting part of the swing arm 200 and the reclining chair frame 100, and the rotary joint 400 is used for changing the horizontal inclination angle of the reclining chair frame 100 around the second axis 204.

The recliner frame 100 is typically fitted with a soft cloth cover to support the body lying within the recliner frame 100. The X direction 102 is the same direction as the longitudinal direction (i.e., the body length direction) in which the body lies, and the Y direction 101 is the lateral direction in which the body lies. The recliner frame 100 is generally oval in shape to better distinguish the X-direction 102 from the Y-direction 101. If the reclining chair frame 100 has other shapes, the X direction 102 and the Y direction 101 can be determined according to the lying posture. The higher positioned first side 103 corresponds to the head position and the lower positioned second side 104 corresponds to the foot position.

The base 300 is placed on the ground, the mounting side 301 is in the same direction as the first side 103 where the head is located when lying down, and the extension side 302 is in the same direction as the second side 104 where the feet are located.

The swing arm 200 is supported between the reclining chair frame 100 and the base 300, and the swing arm 200 drives the reclining chair frame 100 to swing. The bottom end of the swing arm 200 in this embodiment extends towards the mounting side 301 of the base 300, i.e. below the first side 103 of the recliner frame 100, and the bottom end of the swing arm 200 rotates about a first axis 205 that exits from the mounting side 301. The upper end of the swing arm 200 is connected to the middle parts of the two sides of the reclining chair frame 100 in the width direction through the two supporting parts 201, and when the reclining chair frame 100 is rocked, the swing amplitude of the first side 103 at a high position is small, so that the brain development of children is prevented from being influenced.

The reclining chair frame 100 and the supporting portion 201 of the swing arm 200 can rotate around the rotation joint 400, and the horizontal tilt angle of the reclining chair frame 100 can be adjusted to switch between a sitting state (shown in fig. 1) and a lying state (shown in fig. 2). For example, in the sitting position shown in fig. 1, the reclining chair frame 100 has an inclination of 22 degrees from the horizontal ground; in the lying state shown in fig. 2, the reclining chair frame 100 has an inclination angle of 5 degrees with respect to the horizontal ground; further, in actual use, the horizontal tilt angle of the reclining chair frame 100 can be adjusted by the consumer as required. The second axis 204 in this embodiment is located in the Y direction 101.

As a further technical effect in this embodiment, the position of the first axis 205 is changed to be located on the first side 103 of the reclining chair frame 100, which is also more beneficial to the angle adjustment of the reclining chair frame 100, and when the horizontal tilt angle is larger, the lifting height of the first side 103 is smaller, so as to reduce the shaking of the head of the baby.

In another embodiment, the recliner chair frame 100 is a ring-shaped frame of unitary construction. The recliner frame 100 is generally a hollow or solid metal tube, and the integral structure of the recliner frame is formed by casting or bending a single metal tube.

In another embodiment, the recliner chair frame 100 is formed by splicing at least two components, preferably arc-shaped metal tubes, and after two adjacent metal tubes are joined by welding or other connecting members, the two metal tubes are spliced into an annular recliner chair frame 100.

In another embodiment, the horizontal tilt angle in the X-direction 102 is changed by the recliner frame 100 about the second axis 204. The horizontal tilt angle of the recliner frame 100 has two extremes, with the first side 103 not being lower than the second side 104 at either extreme.

For convenience of description, the above-mentioned X direction 102 and Y direction 101 are defined, wherein the X direction 102 corresponds to a longitudinal direction when the lying is driven, and the Y direction corresponds to a lateral direction when the lying is driven. For example, when the couch frame 100 in fig. 1 is oval, the dimension in the X-direction 102 is larger than the Y-direction 101.

The two limit positions correspond to the sitting state and the lying state of the reclining chair frame 100, respectively, and the middle position is the reclining state; no matter what use state the recliner frame 100 is in, the first side 103 should be kept no lower than the second side 104, so as to ensure the use safety.
