[0058] Example 6

[0059] This embodiment is based on embodiment 1 or 5, see reference. Figures 9 to 16 The lifting control device 4 includes a motor 41, a worm gear housing 40, and a connecting plate 42. The motor 41 is used to drive and control the rotation of the output shaft 401 on the worm gear housing 40. Both ends of the output shaft 401 extend outside the worm gear housing 40. Both ends of the output shaft 401 are connected to the eccentric bushing 402. The eccentric bushing is connected to the connecting plate 42. The connecting plate 42 is connected to the seat frame 2 through a transmission assembly.

[0060] In use, the lifting control device is driven by a motor. The motor 41 drives the output shaft 401 through the worm gear housing 400. The rotation of the output shaft 401 drives the eccentric bushing 402 to rotate eccentrically, which in turn drives the connecting plate 42 to move up and down, thus achieving the up-and-down rocking motion of the seat frame 2. The overall structure is simple, with high operational stability and low noise. A bearing is provided between the eccentric bushing 402 and the connecting plate 42. The bearing is concealed inside the connecting plate 42 by a bearing cover and screws. There are two connecting plates 42, and they are arranged in parallel. The worm gear housing has a worm gear transmission structure and a gear transmission structure. The worm gear housing is an existing structure and will not be described in detail in this application. The motor 41 is fixed to the base 1 by a motor mount.

[0061] As an optional implementation of this embodiment, the transmission assembly includes a transmission shaft 45, a snap-fit ​​plate 44, and a bushing 46 fitted on the outside of the transmission shaft 45. The transmission shaft 45 is connected to the end of the connecting plate 42 away from the output shaft. The bushing 46 is engaged with the snap-fit ​​plate 44. The snap-fit ​​plate 44 is connected to the seat frame 2. The bushing 46 is a rubber sleeve. The outer side of the bushing 46 has a stepped structure to better block the snap-fit ​​plate 44. A positioning bushing is provided between the transmission shaft 45 and the connecting plate 42.

[0062] In use, the snap-fit ​​plate 44 is provided with a snap-fit ​​interface that is compatible with the seat frame 2, and the snap-fit ​​interface of the snap-fit ​​plate 44 is engaged with the seat frame 2; the drive shaft 45 can also be a bolt structure, with a nut screwed on the end of the bolt to fix it to the connecting plate.

[0063] As an optional embodiment of this example, the top of the snap-fit ​​plate 44 is provided with an opening, the bushing 46 is fitted into the opening and pressed and fixed by the limiting block 47. The opening is in the shape of an inverted 7. The bushing 46 is installed on the short side of the opening, and the limiting block 47 is located on the long side of the opening. The side of the limiting block 47 that presses against the bushing 46 is provided with an arc-shaped surface that is adapted to the outer edge of the bushing 46. The limiting block 47 and the snap-fit ​​plate 44 are fastened together with screws.

[0064] As an optional implementation of this embodiment, based on embodiment 8, an electric push rod 7 is installed below the seat frame 2. The non-push rod end of the electric push rod 7 is connected to the snap-fit ​​plate 44 by a fastening shaft to press the snap-fit ​​plate 44, thereby ensuring that the snap-fit ​​plate 44 will not loosen from the seat frame 2 when the electric rocking chair is rocking. The push rod end of the electric push rod 7 is connected to the support rod by two parallel connecting ears and a pin.

[0065] Example 7

[0066] This embodiment is based on any of the above embodiments, see below. Figure 2 The backrest 3 has plug-in buckles 31 on both sides, and the plug-in buckles 31 have slots. The seat frame 2 has plug-in plates on both sides for interlocking with the slots, which facilitates the disassembly and assembly of the backrest 3 and the seat frame 2.

[0067] Example 8

[0068] This embodiment is based on any of the above embodiments, see below. Figures 1 to 5 The bottom of the seat frame 2 is equipped with a limit post, and the limit post is equipped with a roller 24. The base 2 near the backrest 3 is equipped with a stop post 12 to limit the bottom frame 2 from falling to the lowest position. The stop post 12 abuts against the roller 24 to prevent the seat frame 2 from swinging left and right.

[0069] As an optional implementation, the roller 24 is a flexible wheel, and preferably the roller 24 is made of rubber.

[0070] There are two limit posts and two stop posts 12. The stop posts 12 can limit the lowest descent position of the seat frame. Through the contact between the stop posts and the rollers, the seat frame and the base of the electric rocking chair are less likely to become loose or misaligned during transportation.

[0071] Example 9

[0072] This embodiment is based on any of the above embodiments, see below. Figure 1 The base 1 has several support feet at the bottom, and the seat frame 2 has a spring support structure. In order to improve the comfort and aesthetics of the electric rocking chair, a cover and corresponding elastic pads can be installed on the seat frame, left armrest, right armrest and backrest.

[0073] The working process of this utility model:

[0074] During operation, the electric rocking chair starts the motor 41, which drives the output wheel to rotate. The rotation of the output wheel drives the eccentric shaft 43 to rotate, and the rotation of the eccentric shaft 43 drives the connecting plate 42 to move up and down synchronously. The up and down movement of the connecting plate 42 is transmitted through the transmission shaft 45, the snap-fit ​​plate 44 and the transmission rod 23, which in turn drives the folding telescopic frame 21 and the end of the seat frame 2 near the backrest 3 to move up and down synchronously. The middle part of the folding telescopic frame 21 and the seat frame 2 rotates around the bolts, nuts or pins on the support plate 11, so that the two ends of the folding telescopic frame 21 and the seat frame 2 are in a rocking motion state. Through the abutting cooperation between the roller 24 of the limiting post below the transmission rod 23 and the stop post 12 on the base 1, the electric rocking chair is not easy to shift left and right during transportation, and the seat frame 2 also maintains longitudinal movement when rocking up and down.

[0075] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
