[0004] The technical scheme adopted by the application to solve the above technical problems comprises: an electrically-driven rocking chair, which comprises a chassis assembly, a front rocking rod, a rear rocking rod, a rear fixing rod and a seat frame. One side plate is arranged on each side of the chassis assembly. The front rocking rod and the rear rocking rod are hingedly connected to each side plate. The two rear rocking rods are fixedly connected through the rear fixing rod. The seat frame is installed on the front rocking rod and the rear rocking rod. The electrically-driven rocking chair is characterized in that a rocking mechanism is further arranged. The rocking mechanism comprises a rear universal bearing, a connecting rod, a front universal bearing, a connecting shaft and an eccentric wheel. The rear end of the connecting rod is connected to the rear fixing rod through the rear universal bearing. The front end of the connecting rod is connected to the front universal bearing. The shaft hole at the front end of the front universal bearing is sleeved with the connecting shaft in the up-down direction. The connecting shaft is sleeved into the eccentric wheel shaft hole in the lower part of the eccentric wheel. A rocking motor is installed on the chassis assembly. The driving shaft of the rocking motor is fixedly connected to the eccentric wheel. The center line of the connecting shaft and the center line of the driving shaft of the rocking motor are both perpendicular to the bottom surface of the chassis and are not on the same straight line. The electrically-driven rocking chair provided by the application is driven by a motor and converts rotation into forward and backward rocking movements through an eccentric wheel. The electrically-driven rocking chair is relatively simple in structure and reduces the space occupation of the entire rocking mechanism.

[0005] The rear end of the connecting rod is threadedly connected to the rear universal bearing, so that the length of the connecting rod after being connected to the rear universal bearing can be properly adjusted.

[0006] The front end of the connecting rod is threadedly connected to the front universal bearing, so that the length of the connecting rod after being connected to the front universal bearing can be properly adjusted.

[0007] The distance between the center line of the driving shaft of the rocking motor and the center line of the connecting shaft is 18 mm.

[0008] Compared with the prior art, this application has the following advantages and effects: simple structure, small space occupation, and small impact on the swing motor. Attached Figure Description

Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. These embodiments are illustrative of the present application, but the present application is not limited to them. Figure 4 The right side is the front, and the left side is the back.

[0018] See Figures 1-6The electrically-driven rocking chair of the present application comprises a chassis assembly 1, a front rocking rod 2, a rear rocking rod 3, a rear fixed rod 4, and a seat frame 6. The chassis assembly 1 is provided with a side plate 11 on each side. The front rocking rod 2 and the rear rocking rod 3 are hingedly connected to each side plate 11. The two rear rocking rods 3 are fixedly connected by the rear fixed rod 4. The seat frame 6 is installed on the front rocking rod 2 and the rear rocking rod 3 and can rock forward and backward. The present application is characterized in that a rocking mechanism 5 is further provided. The rocking mechanism 5 comprises a rear universal bearing 51, a connecting rod 52, a front universal bearing 53, a connecting shaft 54, and an eccentric wheel 55. The rear end of the connecting rod 52 is connected to the rear fixed rod 4 through the rear universal bearing 51. The front end of the connecting rod 52 is connected to the front universal bearing 53. The shaft hole 531 at the front end of the front universal bearing 53 is sleeved with the connecting shaft 54 in the up-down direction. The connecting shaft 54 is sleeved into the eccentric wheel shaft hole 551 of the eccentric wheel 55 at the lower part. The driving shaft of the rocking motor 56 installed on the chassis assembly 1 is fixedly connected to the eccentric wheel 55. The eccentric wheel 55 is driven to rotate around the center line 561 of the rocking motor driving shaft. When the connecting shaft 54 rotates to the most forward position (see Figure 2 ), the rocking mechanism 5 drives the rear fixed rod 4 to move forward. The rear fixed rod 4 drives the rear rocking rod 3, the seat frame 6, and the front rocking rod 2 to move forward as a whole. The present application is located at the maximum forward rocking position. When the connecting shaft 54 rotates to the most backward position (see Figure 3 ), the rocking mechanism 5 drives the rear fixed rod 4 to move backward. The rear fixed rod 4 drives the rear rocking rod 3, the seat frame 6, and the front rocking rod 2 to move backward as a whole. The present application is located at the maximum backward rocking position. The present application provides a user with an electrically-driven rocking chair in which the rotation is converted into forward and backward rocking through an eccentric wheel. The rocking chair is relatively simple and occupies a small space.

[0019] The rear universal bearing 51 is threadedly connected to the rear end of the connecting rod 52, which facilitates the appropriate adjustment of the length of the connecting rod 52 after being connected to the rear universal bearing 51.

[0020] The front universal bearing 53 is threadedly connected to the front end of the connecting rod 52, which facilitates the appropriate adjustment of the length of the connecting rod 52 after being connected to the front universal bearing 53.

[0021] The distance between the center line 561 of the driving shaft of the rocking motor 56 and the center line of the connecting shaft 54 (eccentric wheel shaft hole 551) is 18 mm.

[0022] The rocking process of the present application is as follows:

[0023] When the user wants to swing in any posture (for example, sitting posture or lying posture, the sitting posture is taken as an example in the embodiment, and the swinging process in the lying posture is similar), the swinging motor 56 is started by the controller of the prior art, the swinging motor 56 drives the eccentric wheel 55 to rotate, drives the connecting shaft 54 to rotate around the center line 561 of the swinging motor driving shaft, and thus drives the rear fixed rod 4 to move forward and backward through the swinging mechanism 5, and drives the entire seat frame 6 installed on the swinging rod (consisting of the front swinging rod 2 and the rear swinging rod 3) to realize the forward and backward swinging repeatedly.

[0024] The seat frame 6 and the posture (change between the sitting posture and the lying posture) adjusting motor 7 of the application are prior art, and are not described in detail.
