[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0029] like Figure 1-3 As shown, this embodiment provides a smart rocking chair, which includes a seat panel 100, a backrest panel 110 provided on the seat panel 100, and support legs 120 provided at the bottom of the seat panel 100. The seat panel 100 can be placed on the ground via the support legs 120, so that the user can sit and rest on the seat panel 100. Furthermore, the support legs 120 are curved, so that the support legs 120 can rock to a certain extent under the action of external force, thereby enabling the seat panel 100 connected to the support legs 120 to rock, thereby improving the comfort of the user sitting and resting on the seat panel 100.

[0030] Furthermore, the rocking chair includes a base 200, on which the seat panel 100 is placed via support legs 120, so that the seat panel 100 can rock on the base 200 via the support legs 120. A driving device is also fixedly mounted on the base 200, and the driving device can be connected to any one or more of the backrest 110, the seat panel 100, and the support legs 120. When a user sits on the seat panel 100 to rest, the driving device can directly or indirectly apply a force to the support legs 120, so that the backrest 110 and the seat panel 100 can rock on the base 200 via the support legs 120, thereby improving the user's rest comfort.

[0031] Furthermore, the above-mentioned driving device can establish a communication connection with an external controller. After the user sits on the seat 100, he can use the external controller to operate the driving device to open or close, and adjust the speed at which the driving device drives the support leg 120 to swing, etc.

[0032] It can be understood that the swinging of the support leg 120 of this embodiment is achieved by the force applied by the driving device, and there is no need for the user to actively apply force. The user only needs to sit on the seat 100. Furthermore, the driving device can drive the swinging of the support leg 120 for a long time in a relatively stable manner, and when the driving device stops working, since the driving device is connected to one or more of the backrest 110, the seat 100 and the support leg 120, the driving device can assist the stability of the rocking chair to a certain extent, making it easier for the user to stand up from the seat 100, and of course it is also convenient for the user to sit on the seat 100.

[0033] In some embodiments, a motor 210 is used as a driving device, and the motor 210 is fixedly installed on the base 200. The output shaft of the motor 210 is then connected to one or more of the backrest 110, the seat plate 100 and the support leg 120. The motor 210 can better drive the support leg 120 to swing on the base 200.

[0034] It should be noted that the driving device can also be replaced by an electric telescopic rod, a cylinder, etc.; the output shaft of the motor 210 can be used for telescopic movement or rotational movement; as long as the above can drive the support leg 120 to perform a swinging movement, there is no special limitation on this.

[0035] In some embodiments, the output shaft of the motor 210 is connected to one or more of the backrest 110 , the seat plate 100 and the support leg 120 via a first universal joint 211 .

[0036] It can be understood that the swinging movement of the support leg 120 does not move in a straight line, and the position of the motor 210 is fixed. The motor 210 is connected to one or more of the backrest 110, the seat plate 100 and the support leg 120 through the first universal joint 211, which can better realize the driving of the support leg 120 by the motor 210, and the motor 210 will not restrict the swinging of the support leg 120, so that the swinging of the support leg 120 is smoother.

[0037] In some embodiments, the output shaft of the motor 210 is connected to the first push rod 212 through the first universal joint 211, and the first push rod 212 is connected to one or more of the backrest 110, the seat plate 100 and the support leg 120 through the second universal joint 213. That is, the first universal joint 211 is not directly connected to the rocking chair, but is indirectly connected to the rocking chair through the first push rod 212 and the second universal joint 213.

[0038] It can be understood that the first universal joint 211 can ensure the free movement between the output shaft of the motor 210 and the first push rod 212, and the second universal joint 213 can ensure the free movement between the first push rod 212 and the rocking chair. The cooperation of the first universal joint 211, the first push rod 212 and the second universal joint 213 can better ensure that the motor 210 with a fixed position drives the support leg 120 and avoids restricting the swinging of the support leg 120.

[0039] In some embodiments, a mounting rod 220 is also provided on the base 200, and the above-mentioned motor 210 is fixedly mounted on the mounting rod 220, and a second push rod 214 is provided on the mounting rod 220, wherein the axial direction of the second push rod 214 is basically perpendicular to the ground, and the second push rod 214 can reciprocate in the vertical direction relative to the mounting rod 220.

[0040] It should be noted that the axial direction of the second push rod 214 is basically perpendicular to the ground, which means that the axial direction of the second push rod 214 can be perpendicular to the ground, or it can be at a certain angle to the ground. For example, the axis of the second push rod 214 can be at an angle of 5 degrees to the vertical direction and swing within a range of less than 5 degrees. It can further avoid restricting the swinging of the rocking chair and make the rocking chair swing more freely.

[0041] Furthermore, the output shaft of the motor 210 is connected to the first universal joint 211 through the second push rod 214. During the operation of the motor 210, the output shaft of the motor 210 will drive the second push rod 214, so that the second push rod 214 moves back and forth in a basically vertical direction, and then the second push rod 214 drives the support leg 120 to swing on the base 200 through the first universal joint 211, the first push rod 212 and the second universal joint 213.

[0042] In some embodiments, a first stopper 221 is provided on the mounting rod 220. A through hole (not shown) is provided on the first stopper 221, the axis of which is perpendicular to the ground. Furthermore, a second push rod 214 passes through the through hole. When driven by the motor 210, the second push rod 214 reciprocates within the through hole.

[0043] It is understandable that passing the second push rod 214 through the through hole can better limit the second push rod 214, so as to ensure that the second push rod 214 moves in a substantially vertical direction, thereby ensuring the stability of the movement of the second push rod 214.

[0044] In some embodiments, a connecting rod mechanism 215 is provided on the output shaft of the motor 210 , and the output shaft of the motor 210 is connected to the second push rod 214 through the connecting rod mechanism 215 to ensure driving of the second push rod 214 .

[0045] It should be noted that in this embodiment, the output shaft of the motor 210 performs rotational motion, and the provided connecting rod mechanism 215 can transmit the rotational motion of the output shaft of the motor 210 to the second push rod 214, thereby driving the second push rod 214 to perform linear motion.

[0046] In some embodiments, the first push rod 212 is specifically connected to the backrest 110 of the rocking chair through the second universal joint 213. When the motor 210 is working, it drives the second push rod 214 to move through the connecting rod mechanism 215. The second push rod 214 then drives the backrest 110 through the first universal joint 211, the first push rod 212 and the second universal joint 213, thereby causing the backrest 110 and the seat 100 to swing on the base 200 through the support legs 120.

[0047] In some embodiments, the mounting rod 220 is entirely disposed on the rear side of the backrest 110 of the rocking chair, and a second limiting block 222 is disposed on the mounting rod 220 , so that the second limiting block 222 is also located on the rear side of the backrest 110 .

[0048] Furthermore, the second stopper 222 can limit the extent to which the seat plate 100 can swing backward. It is understood that if the rocking chair swings backward too far via the support legs 120, there is a risk of the rocking chair tipping over. Therefore, the provision of the second stopper 222 in this embodiment can effectively prevent the rocking chair from swinging backward too far. Specifically, if the rocking chair swings backward too far, the second stopper 222 will contact the seat plate 100 and provide resistance.

[0049] In some embodiments, a buffer pad (not shown in the figure) is provided on the side wall of the second limiting block 222 facing the seat plate 100 . The buffer pad can be made of elastic material such as a rubber pad.

[0050] When the rocking chair swings backward too much, the seat plate 100 will first contact the buffer pad on the second limit block 222, and then the seat plate 100 will squeeze the buffer pad to avoid the direct collision between the second limit block 222 and the seat plate 100 causing a sense of frustration and noise.

[0051] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
