Detailed Implementation Methods

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 11 As shown, this utility model provides a rocking chair, including a base 1. A rotating seat 2, which can swing relative to the base 1 in a vertical direction around a first axis A, is connected to the base 1. A frame assembly 3, which can move in a horizontal direction, is connected to the rotating seat 2. A first driving device 4 is provided on the base 1. A transmission assembly 5, which can be driven by the first driving device 4 to rotate the rotating seat 2, is provided between the first driving device 4 and the rotating seat 2. The transmission assembly 5 includes a movable part 51 connected to the first driving device 4 and driven by the first driving device 4 to move back and forth relative to the base 1. The movable part 51 is provided with a first tooth 52. The rotating seat 2 is provided with a second tooth 53 that can mesh with the first tooth 52 and be driven by the first tooth 52 to rotate the rotating seat 2. A second driving device 6, which can make the frame assembly 3 move laterally, is provided between the rotating seat 2 and the frame assembly 3.

[0031] When the rocking chair is needed, the second drive device 6 is activated. After the second drive device 6 is activated, the frame assembly 3 moves on the horizontal plane. Then the first drive device 4 is activated. After the first drive device 4 is activated, it drives the movable part 51 to move. The movable part 51 swings back and forth relative to the base 1. Since the first tooth 52 and the second tooth 53 on the movable part 51 mesh and transmit power, when the movable part 51 swings back and forth, it drives the rotating seat 2 to swing around the first axis A on the vertical plane. The rotating seat 2 drives the frame assembly 3 to swing accordingly. The rocking chair can then achieve swinging on the vertical plane and movement on the horizontal plane, and move in two different dimensions, making it more entertaining and convenient for users to play with children.

[0032] The first driving device 4 includes a first worm gear 41, on which a first pulley 42 is provided. The first driving device 4 also includes a second pulley 43, which drives the first pulley 42 to rotate via a first belt and has a diameter smaller than the first pulley 42. A first driving motor 44 is connected to the second pulley 43 to drive its rotation. The base 1 is also provided with a first worm wheel 45 that can cooperate with the first worm gear 41. The first worm wheel 45 is provided with a rotating member 46 that can rotate with it. The movable member 51 is connected to the rotating member 46, and the rotation axis B of the movable member 51 is offset from the rotation axis C of the first worm wheel 45. In use, the rocking chair of this invention is driven by a first drive motor 44 to rotate a second pulley 43. The second pulley 43, via a belt, drives a first pulley 42 to rotate. A first worm gear 41 at one end of the first pulley 42 engages with a first worm wheel 45, thereby driving a rotating component 46 to rotate. The rotating component 46 then moves a movable component 51. Because the rotation axis B of the movable component 51 is offset from the rotation axis C of the first worm wheel 45, the movable component 51 can swing back and forth, thus enabling the rotating seat 2 to swing back and forth in a vertical plane. The use of belt transmission makes the transmission process smoother. Furthermore, the diameter of the first pulley 42 is larger than that of the second pulley 43, achieving a first-stage speed reduction. The engagement of the first worm gear 41 and the first worm wheel 45 achieves a second-stage speed reduction. Additionally, the first drive motor 44 rotates in one direction without needing to change direction, resulting in less vibration and a smoother transmission process. This reduces noise during transmission and makes it more convenient for children to lie down and rest.

[0033] The movable component 51 includes a connecting rod 511 connected to the rotating component 46. The front end of the connecting rod 511 is rotatably connected to a slider 512 that can slide back and forth relative to the base 1. The slider 512 has a first tooth 52. Through the engagement of the second tooth 53 and the first tooth 52, the rotating base 2 can swing back and forth when the movable component 51 moves linearly. Furthermore, when the connecting rod 511 moves with the rotating component 46, the front end of the connecting rod 511 rotates relative to the slider 512, pulling the slider 512 to move.

[0034] The frame assembly 3 includes a connecting shell 31 connected to the rotating base 2, and support legs 32 extending to the left and right sides connected to the connecting shell 31. The frame body 33 is connected to the support legs 32. The frame body 33 can be used by simply covering it with a cloth cover.

[0035] The rotating seat 2 includes a seat body 21. The second driving device 6 includes a driving shaft 61 disposed in the connecting shell 31 and a second driving assembly 62 capable of driving the driving shaft 61 to rotate. An extension rod 63 extending outward is fixedly connected to the driving shaft 61. A rotating rod 64 is provided between the end of the extension rod 63 and the seat body 21 and is hinged to both. The seat body 21 is also provided with a sliding seat 65 that can slide laterally relative to it and a guide rod 66 that guides the sliding seat 65 to slide. The connecting shell 31 is fixedly connected to the sliding seat 65 so that when the driving shaft 61 rotates, the connecting shell 31 can slide and swing relative to the seat body 21 together with the sliding seat 65. The second tooth 53 is disposed on the seat body 21 in the circumferential direction. When the second drive assembly 62 is activated, it drives the drive shaft 61 to rotate. The extension rod 63 on the drive shaft 61 can then rotate relative to the rotating rod 64, which in turn can rotate relative to the seat 21. At this time, the sliding seat 65 inside the seat 21 can slide laterally on the guide rod 66. The connecting shell 31, which is fixedly connected to the sliding seat 65, can slide left and right relative to the seat 21 on the horizontal plane together with the sliding seat 65, thereby realizing the left and right swing of the frame assembly 3. This utility model uses the second drive assembly 62 to drive the drive shaft 61, extension rod 63, and rotating rod 64 to rotate, thereby completing the left and right swing of the rocking chair. The vibration is small, making the transmission process smoother, reducing noise, and improving the comfort of children when resting.

[0036] The second drive assembly 62 is fixedly connected inside the connecting shell 31. The second drive assembly 62 includes a second worm gear 621, on which a third pulley 622 is mounted. The second drive assembly 62 also includes a fourth pulley 623, smaller in diameter than the third pulley 622, which drives the third pulley 622 to rotate via a second belt. A second drive motor 624 is connected to the fourth pulley 623 to drive its rotation. A second worm wheel 625, which engages with the second worm gear 621, is mounted on the drive shaft 61. In use, the rocking chair of this invention is driven by the second drive motor 624 to rotate the fourth pulley 623. The fourth pulley 623 then drives the third pulley 622 to rotate via a belt. The second worm gear 621 at one end of the third pulley 622 engages with the second worm wheel 625 on the drive shaft 61, thereby driving the drive shaft 61 to rotate, ultimately achieving the left-right swinging of the frame assembly 3. The use of belt drive makes the transmission process smoother. At the same time, the diameter of the third pulley 622 is larger than that of the fourth pulley 623, thus achieving the purpose of first-level speed reduction. The cooperation between the second worm gear 621 and the second worm wheel 625 achieves the purpose of second-level speed reduction. Meanwhile, the second drive motor 624 rotates in one direction without the need to change direction, resulting in less vibration and making the transmission process smoother. This also reduces noise during the transmission process and makes it more convenient for children to lie down and rest.

[0037] The sliding seat 65 includes a sliding seat body 651 that can slide laterally on the guide rod 66. The sliding seat body 651 has a protruding insertion part 652. The connecting shell 31 includes an outer shell 311 and a connecting plate 312 fixedly connected thereto. One side of the connecting plate 312, located inside the outer shell 311, has an insertion interface 3121 for the insertion part 652 to be inserted into, so that the sliding seat 65 can be connected to the connecting shell 31. The insertion interface 3121 is fixed to the insertion part 652, thereby facilitating the sliding seat 65 to drive the connecting shell 31 to swing.

[0038] The guide rods 66 are two horizontal rods arranged vertically. These two guide rods 66 make the sliding seat 65 slide more smoothly on the guide rods 66, improving the comfort of children.
