Referring to fig. 1 and 3, in the base 100 according to the first embodiment of the present invention, the base 100 is placed on a supporting surface. The support surface is typically a floor surface, but may be other surfaces for support. Two shaft holes, namely a first shaft hole 101 and a second shaft hole 102, are formed in the base 100, and each shaft hole is used for mounting a rotating shaft. It will be appreciated that the number of shaft holes may also be three or more for mounting more shafts. Each shaft hole has an axis of rotation such that the shaft is rotatable about the axis of the shaft hole in which it is located when mounted in the shaft hole. In some embodiments, the centerline of the shaft bore is the axis about which the axis of rotation rotates. The axis of rotation of the at least one shaft bore is arranged non-parallel to the support surface and non-perpendicular to it, such that when the rotary shaft is mounted in the shaft bore, the at least one mounting shaft is arranged obliquely with respect to the support surface, i.e. when the at least one rotary shaft is rotated, the structure fixedly connected to the rotary shaft does not move in the same horizontal plane with respect to the support surface.

Referring to fig. 1, 2, 5, 6, in some embodiments, there is at least one shaft bore with an axis of rotation that is angularly disposed non-parallel to an axis of rotation of at least one of the other shaft bores. That is, the rotation axes installed in the shaft holes of the base 100 are not all arranged in parallel, that is, the rotation rhythm of each rotation axis is not synchronous, and therefore, the rotation rhythm of the part connected with each rotation axis is not consistent.

Referring to FIG. 2, in some embodiments, the axes of rotation of all of the axle bores are disposed non-parallel, non-perpendicularly inclined relative to the support surface. That is, the rotation of all the rotating shafts installed in the shaft holes, which drives the components connected with the rotating shafts to rotate relative to the supporting surface, is not the rotation within the same horizontal plane. Referring to fig. 2, the rotational axis of the first shaft hole 101 is a first axis 112, and the rotational axis of the second shaft hole 102 is a second axis 113. It is apparent that the first axis 112 is not parallel to the second axis 113. In fig. 2 both the first axis 112 and the second axis 113 are arranged at an angle to the support surface.

In some embodiments, the number of the shaft holes is two, and two rotating shafts are mounted on the base 100, and referring to fig. 1 and 5, a first shaft hole 101 and a second shaft hole 102 are provided. A first rotation shaft 103 is provided in the first shaft hole 101, and a second rotation shaft 104 is provided in the second shaft hole 102.

Referring to fig. 2, in some embodiments, each shaft hole includes at least one cylindrical portion 105, a bearing fitted to the rotating shaft is disposed at the cylindrical portion 105, and an axis of the cylindrical portion 105 coincides with the rotating axis. The rotating shaft can be supported by mounting a bearing in the cylindrical portion 105.

Referring to fig. 2, in some embodiments, each of the shaft holes includes two cylindrical portions 105 spaced apart from each other, a bearing is provided at each of the cylindrical portions 105, and the shaft hole further includes a communication portion 106 communicating the two cylindrical portions 105, and the rotary shaft is fitted to the bearing through the communication portion 106. By providing two separate sections of the cylindrical portion 105, the rotating shaft can be supported at two locations, which is more stable.

Referring to fig. 1-4, in some embodiments, the base 100 includes an installation seat 108 and a supporting seat 109, the shaft holes are all formed in the installation seat 108, the supporting seat 109 is placed on the supporting surface, the installation seat 108 further has a first installation hole 110, the supporting seat 109 has a second installation hole 111 matching with the first installation hole 110, and the fixing element passes through the first installation hole 110 and the second installation hole 111 to fix the installation seat 108 to the supporting seat 109. Therefore, the mounting seat 108 provided with the shaft hole can be detachably connected with the supporting seat 109 for supporting, so that the supporting seat 109 or the mounting seat 108 can be replaced conveniently.

Referring to fig. 5, a rocking assembly 200 according to a second embodiment of the present invention includes a base 100 according to the first embodiment of the present invention, and a rotating shaft is installed in each shaft hole of the base 100. In the rocking assembly 200, at least one axis of rotation is disposed at an angle to the support surface during rocking, so that at least a portion of the rocking assembly 200 does not rotate in the same horizontal plane with respect to the support surface.

Referring to fig. 5, in some embodiments, the wobble assembly 200 further includes a drive assembly 210, the drive assembly 210 being configured to drive at least one rotational shaft to rotate. Since the other ends of the rotating shafts may be connected together through some parts, when one rotating shaft is driven to rotate and swing, the other rotating shafts will rotate and swing together.

Referring to fig. 6, a swing chair 300 according to a third aspect of the present invention comprises the swing assembly 200 of the second aspect of the present invention, and further comprises seat assemblies 310, one end of each of the rotation shafts being disposed within the shaft hole, the other end of each of the rotation shafts being connected to the seat assembly 310, the seat assemblies 310 being not completely fixedly connected to at least one of the rotation shafts. The seat assembly 310 can be driven by the rotating shaft to swing by connecting the seat assembly 310 with the other end of the rotating shaft, and at least one part of the seat assembly 310 does not swing in the same horizontal plane relative to the supporting surface due to the inclined arrangement of the axis of at least one rotating shaft. In some embodiments, when the axes of the two rotating shafts are both obliquely arranged relative to the supporting surface and the axes of the two rotating shafts are not parallel, the swinging rhythms of the two rotating shafts are not consistent, so that the connection between the seat assembly 310 and the at least one rotating shaft is not completely fixed, and the seat assembly 310 and the at least one rotating shaft can move relative to each other to a certain extent due to the inconsistent moving rhythms of the rotating shafts, so that the seat assembly 310 can move without being jammed.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
