[0037] The following further elaborates on the embodiments of the present utility model in conjunction with the accompanying drawings.

[0038] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the rocking chair base includes a support base 100, a support rotating shaft 130, a rotating base 140, and a driving component 200. The rotating base 140 is located above the support base 100. A driving gear 120 is fixedly arranged on the support base 100. The lower end of the support rotating shaft 130 is rotatably connected to the support base 100 and passes through the driving gear 120, and the driving gear 120 is coaxially arranged with the support rotating shaft 130. The rotating base 140 is fixedly connected to the upper end of the support rotating shaft 130, and the support rotating shaft 130 can rotate relative to the support base 100 around the axis of the support rotating shaft 130 so that the rotating base 140 rotates around the axis of the support rotating shaft 130. The driving component 200 is installed in the rotating base 140, and the driving component 200 includes a driving motor 210 and a speed reduction component 220. The input end of the speed reduction component 220 is connected to the driving end of the driving motor 210, and the output end of the speed reduction component 220 is connected to the driving gear 120.

[0039] The driving motor 210 can drive the rotating base 140 and the support rotating shaft 130 to rotate together around the axis of the support rotating shaft 130 through the speed reduction component 220. This rocking chair base can realize the rotation of the rotating base 140 through a simple structure, and is easy to assemble, reduces production costs, and has a small overall volume and a light weight, making it easy to carry.

[0040] Preferably, referring to Figure 2 and Figure 3 , the axis of the support rotating shaft 130 is inclined to the horizontal plane. The axis of the support rotating shaft 130 is neither perpendicular nor parallel to the horizontal plane; in some embodiments, the included angle between the axis of the support rotating shaft 130 and the horizontal plane is an acute angle. It can be understood that referring to Figure 6, a seat 270 is fixedly installed on the rotating base 140. A user sits on the seat 270. The inclined setting of the support rotating shaft 130 enables the user to apply a relatively small force to the seat 270, and then the support rotating shaft 130 can rotate relative to the support base 100. The structure is simple and labor-saving.

[0041] According to some embodiments of the present invention, refer to Figure 2 , the rotating base 140 is provided with a connection hole 141. The upper end of the support rotating shaft 130 passes through the connection hole 141. The outer diameter of the support rotating shaft 130 is larger than the aperture of the connection hole 141, that is, the support rotating shaft 130 and the connection hole 141 are in interference fit, so that the support rotating shaft 130 and the rotating base 140 are relatively fixed. Alternatively, the support rotating shaft 130 and the rotating base 140 are relatively fixed by welding.

[0042] According to some embodiments of the present invention, refer to Figure 2 , the support base 100 is in a cylindrical shape with an upward opening. A bearing 101 is arranged in the inner cavity of the support base 100. The support rotating shaft 130 passes through the bearing 101, so that the support rotating shaft 130 can rotate relative to the support base 100.

[0043] According to some embodiments of the present invention, refer to Figure 3 , a plurality of positioning grooves 110 distributed along the circumferential direction of the support base 100 are arranged on the upper end surface of the support base 100. A plurality of lugs 121 distributed along the circumferential direction of the driving gear 120 are fixedly arranged on the outer peripheral wall of the driving gear 120. The plurality of positioning grooves 110 and the plurality of lugs 121 correspond one by one. When the driving gear 120 is placed on the support base 100 from top to bottom, the lugs 121 are inserted into the positioning grooves 110, so that the support base 100 can limit the rotation of the driving gear 120, and the driving gear 120 cannot rotate around the axis of the support base 100.

[0044] Refer to Figure 3 , the lug 121 is provided with a first threaded hole 122, and the bottom of the positioning groove 110 is provided with a second threaded hole 111. The bolt is threadedly connected to the first threaded hole 122 and the second threaded hole 111 at the same time, so that the support base 100 and the driving gear 120 are relatively fixed.

[0045] According to some embodiments of the present invention, refer to Figure 4 and Figure 5, the speed reduction component 220 includes a housing 230 and a gear set 240. The gear set 240 is disposed within the housing 230. The support rotating shaft 130 passes through the housing 230 and is fixedly connected to the housing 230. The drive motor 210 is installed within the housing 230. The gear set 240 is respectively connected to the drive motor 210 and the drive gear 120. When the drive motor 210 rotates, it can drive the gear set 240 to rotate, thereby causing the gear set 240 and the drive gear 120 to rotate relative to each other, and then driving the speed reduction component 220, the support rotating shaft 130, and the rotating seat 140 to rotate simultaneously.

[0046] Preferably, a counterbore is provided on the side wall of the support rotating shaft 130. The bolt is threadedly connected to the housing 230 and inserted into the counterbore, so that the support rotating shaft 130 and the housing 230 are relatively fixed.

[0047] Further, referring to Figure 5 , the gear set 240 includes a plurality of transmission gears 241 with gradually increasing number of teeth and meshed in sequence. The transmission gear 241 with the least number of teeth is fixedly connected to the motor shaft of the drive motor 210. The transmission gear 241 with the most number of teeth is meshed with the drive gear 120. It can be understood that the gear set 240 can convert the high speed and low torque output by the drive motor 210 into low speed and high torque, so as to drive the support rotating shaft 130 to rotate.

[0048] According to some embodiments of the present invention, referring to Figure 5 , the rocking chair base further includes a disk grating 250 and a grating sensor 260. The disk grating 250 is sleeved and fixedly connected to the motor shaft of the drive motor 210. The grating sensor 260 is installed on the speed reduction component 220. The grating sensor 260 is used to detect the rotation speed of the disk grating 250.

[0049] In the description of this specification, the description referring to the term "some embodiments" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above term does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
