DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings:

Embodiment 1:

Referring to Figures 1-4: In this embodiment, an automatically rocking leisure chair includes a base assembly 1. The four corners of the inner wall of the base assembly 1 are connected to the rocking assembly 2 through a rocking connecting rod 4. The rocking assembly 2 is composed of a rocking frame 201, a rocking drive rod 202 and a rocking drive assembly 3. The rocking frame 201 is located at the inner center of the base assembly 1, the rocking drive assembly 3 is installed at the bottom center of the rocking frame 201, and the rocking drive rod 202 is located on one side of the outer wall of the rocking drive assembly 3.

Referring to Figures 1-4: In this embodiment, the swing drive assembly 3 is composed of a motor 301, a gear 302, a reduction box fixed seat 303, an eccentric disk 304, a bearing 305 and a reduction shaft 306. The motor 301 is fixed at the center of the bottom inner wall of the swing frame 201. The output shaft of the motor 301 is rotatably connected to the reduction shaft 306 through the gear 302. The outer wall of the reduction shaft 306 is rotatably connected to the reduction box fixed seat 303 through the bearing 305. The eccentric disk 304 is fixed to the end of one side of the reduction shaft 306. The output end of the eccentric disk 304 is rotatably connected to one side of the swing drive rod 202.

Referring to Figures 1-4: In this embodiment, the base assembly 1 is composed of a base frame 101 and a connecting ear seat 102. The connecting ear seat 102 is fixedly connected to the upper end of a cross beam on one side of the base frame 101. The interior of the connecting ear seat 102 is rotatably connected to the other side of the swing drive rod 202 through a pin shaft. The four corners of the inner wall of the base frame 101 are rotatably connected to the swing frame 201 through a swing link 4.

The base frame 101 is connected to the swing link 4 through four pins; the swing frame 201 is connected to the swing link 4 through four pins to realize the connection between the base assembly 1 and the swing assembly 2; the motor 301, the gear 302, the reduction box fixing seat 303, and the bearing 305 are installed together through the reduction shaft 306, and the eccentric wheel 304 is locked. The swing drive assembly 3 is locked to the swing assembly 2 through four screws, and the swing drive rod 202 and the connecting rod ear seat 102 are linked to the base assembly 1 and the swing assembly 2 through two pins.

Through the cooperation among the motor 301, the gear 302, the reduction shaft 306, the eccentric disk 304, the swing drive rod 202 and the base assembly 1, the output shaft of the motor 301 can drive the reduction shaft 306 to rotate through the gear 302, thereby driving the eccentric disk 304 to rotate. Since the eccentric disk 304 is connected to the base assembly 1 through the swing drive rod 202, the eccentric disk 304 and the swing drive rod 202 form a connecting rod structure. The continuous eccentric rotation of the eccentric disk 304 will cause the eccentric disk 304 and the swing drive rod 202 to form a connecting rod structure angle. The eccentric disk 304 causes the swinging and shaking due to the constantly changing degree of opening and closing. The swinging and shaking caused by the eccentricity of the eccentric disk 304 reacts on the swing frame 201, thereby driving the upper structure of the recliner to swing. This solution has the following advantages: 1. The swinging produced by this mechanism is similar to the swinging trajectory of a "swing", which is more comfortable than a manual rocking chair. Adding an upper push rod allows swinging in a zero-gravity state, which is more relaxing; 2. Adding a set of reduction motors between the base and the rocking frame pulls the connecting rod through the eccentric wheel to achieve unidirectional or bidirectional swinging. This swinging mechanism is simpler and less expensive.

Working principle:

When the automatic rocking leisure chair is needed, the user can first assemble the whole device as shown in the figure. After the assembly is completed, the upper structure of the reclining chair is installed at the column connection of the rocking frame 201. When in use, the motor 301 is started so that the output shaft of the motor 301 can drive the reduction shaft 306 to rotate through the gear 302, thereby driving the eccentric disk 304 to rotate. Since the eccentric disk 304 is connected to the base assembly 1 through the rocking drive rod 202, the eccentric disk 304 and the rocking drive rod 202 form a connecting rod structure. The continuous eccentric rotation of the eccentric disk 304 will cause the angle and opening degree of the connecting rod structure formed by the eccentric disk 304 and the rocking drive rod 202 to change continuously, causing rocking. The rocking caused by the eccentricity of the eccentric disk 304 reacts on the rocking frame 201, thereby driving the upper structure of the reclining chair to rock. This solution has the following advantages:

1. The swinging motion produced by this mechanism is similar to the swinging trajectory of a "swing", which is more comfortable than the manual rocking chair. The addition of an upper push rod allows the chair to swing in a zero-gravity state, which is more relaxing;

2. Add a set of reduction motors between the base and the swing frame to pull the connecting rod through the eccentric wheel to achieve unidirectional or bidirectional swing. This swing mechanism is simpler and has lower cost.

Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
