[0045] Example

[0046] This embodiment aims to address the problem in the prior art where the swing direction of traditional drive devices is typically fixed to either horizontal or vertical. Changing the direction requires replacing transmission components or readjusting the overall structure, which is cumbersome and fails to meet users' needs for adaptability to various scenarios. Therefore, referring to... Figures 1-5As shown, this embodiment provides an electric rocking device 100 and a rocking chair 200. The rocker arm component 1 includes a connecting rod 11. The connecting rod 11 includes a first universal joint 11a at one end and a second universal joint 11b at the other end. The eccentric member 21 in the driving component 2 can rotate under external force, causing one end of the rocker arm component 1 to perform circular motion and causing the other end of the rocker arm component 1 to shift and swing. The first universal joint 11a and the second universal joint 11b can realize multiple swing directions of the connecting rod 11, and can adaptively swing direction according to the transmission direction. Switching directions does not require replacing the transmission component or readjusting the overall structure, meeting the user's needs for adaptation to multiple scenarios.

[0047] Reference Figures 1-3 As shown, an electric rocking device 100 includes: a rocker arm component 1 and a drive component 2.

[0048] The rocker arm component 1 includes a connecting rod 11; the connecting rod 11 includes a first universal joint 11a disposed at one end of the connecting rod 11 and a second universal joint 11b disposed at the other end of the connecting rod 11; for example, the connecting rod 11 can be a cylindrical metal rod, wherein the first universal joint 11a and the second universal joint 11b can be one or a combination of existing universal joints or fisheye bearings.

[0049] The first universal joint 11a is rotatably connected to the rocking bracket 202 or the swing arm 203 of the rocking chair 200. It should be noted that the direction of the rocking bracket 202 or the swing arm 203 is consistent with the driving direction of the rocker component 1.

[0050] The drive component 2 is detachably connected to the fixed bracket 201 of the rocking chair 200. The drive component 2 includes an eccentric member 21, which includes a rotating connecting end 21a and an eccentric connecting end 21b. The eccentric connecting end 21b is rotatably connected to the second universal joint 11b. Under the action of an external force, the rotating connecting end 21a can rotate, driving the eccentric connecting end 21b to perform a circular motion around the rotating connecting end 21a. The other end of the rocker arm component 1 can follow the rotating connecting end 21a in a circular motion, causing one end of the rocker arm component 1 to shift and swing. For example, the eccentric member 21 can be a square steel bar, with a square groove at one end serving as the rotating connecting end 21a and a circular groove at the other end serving as the eccentric connecting end 21b. In some embodiments, multiple eccentric connecting ends 21b can be provided to adapt to rocker arm components 1 of various sizes. In some embodiments, the eccentric member 21 can also be an eccentric wheel structure.

[0051] Reference Figure 1As shown, in some embodiments, the eccentric member 21 is arranged laterally relative to the fixed bracket 201, and the eccentric member 21 can make circular motion in the horizontal direction, that is, the axis of the rotating connection end 21a is the vertical direction.

[0052] Reference Figure 2 As shown, in some embodiments, the eccentric member 21 is longitudinally arranged relative to the fixed bracket 201, and the eccentric member 21 is capable of circumferential movement in the longitudinal direction, that is, the axis of the rotating connection end 21a is in the horizontal direction. It should be noted that the lateral or longitudinal arrangement is based on the fixed bracket 201.

[0053] Reference Figure 2 As shown, in some embodiments, in the initial state, the rotation axis of the first universal joint 11a is parallel to the rotation axis of the second universal joint 11b; refer to Figure 3 As shown, in some embodiments, in the initial state, the rotation axis of the first universal joint 11a is perpendicular to the rotation axis of the second universal joint 11b. It should be noted that the rotation axes of the first universal joint 11a and the second universal joint 11b can be parallel or perpendicular to each other, and multiple swing directions can provide various connection methods for the connecting rod 11 to meet the user's needs for adapting to multiple scenarios or the swing direction of a specific installation position. For example, the first universal joint 11a and the second universal joint 11b use spherical bearings; the initial state refers to the state where the axis of the spherical bearing coincides with the axis of the through groove where the spherical bearing is installed.

[0054] Reference Figure 4 As shown, in some embodiments, the rocker arm component 1 further includes:

[0055] A first universal joint 12 adapted to the first universal joint 11a; the first universal joint 12 can extend from at least one side of the first universal joint 11a;

[0056] A second universal joint 13 is adapted to the second universal joint 11b; the second universal joint 13 can extend from at least one side of the second universal joint 11b; wherein, one end of the second universal joint 13 is used for detachable connection with the eccentric member 21; one end of the first universal joint 12 is used for detachable connection with the swing bracket 202 or the swing arm 203. For example, the first universal joint 12 and the second universal joint 13 can be threaded rods with nuts.

[0057] Reference Figures 1-4As shown, in some embodiments, a reset component 3 is also included, comprising a processor and a sensor 31. The processor is electrically connected to the drive component 2; the sensor 31 is disposed on the drive component 2, and its position corresponds to the area where the eccentric member 21 performs circular motion; when the eccentric member 21 rotates to correspond with the sensor 31, the rocking chair 200 resets; the processor can receive the sensing signal from the sensor 31 and shut down the drive component 2. In some embodiments, the sensor 31 is a Hall sensor 31, and the processor is electrically connected to the sensor 31, triggering a signal by detecting the position of the magnet on the eccentric member 21. The Hall sensor 31 is fixed to the housing of the reduction gearbox 23 of the drive component 2, and the position of the sensor 31 is adjusted so that it is directly opposite the "reset point" of the eccentric member 21's circular trajectory; this can be the highest or lowest point of the eccentric member 21's movement. A neodymium iron boron magnet is embedded in the eccentric connection end 21b of the eccentric member 21, ensuring that the signal is triggered when the magnet is aligned with the sensor 31. Exemplarily, the processor can be a microcontroller integrating PWM output and interrupt input functions.

[0058] It should be added that the drive component 2 also includes a drive motor 22 and a reduction gearbox 23 that is connected to the drive motor 22. The output shaft of the reduction gearbox 23 is connected to the eccentric component 21. The reset component 3 also includes a control button. After the user presses the control button, the drive motor 22 continues to run until the sensor 31 detects the reset signal. The processor interrupts and stops the PWM output. Electromagnetic braking is achieved by short-circuiting the motor winding through the motor drive module, and the drive motor 22 stops. The static position of the swing bracket 202 is approximately the same as the preset reset position.

[0059] Reference Figure 4 As shown, in some embodiments, the rocker arm component 1 further includes a washer body 14; a through hole 11a1 is provided in the middle of the first universal joint 11a, and a washer body 14 is provided at each of the two ends of the through hole 11a1. The end face of the washer body 14 that contacts the through hole 11a1 is conical; the first universal connector 12 is a screw with a nut. The screw passes through the washer body 14 and the through hole 11a1, and is threadedly connected to the screw through the nut. The washer body 14 is clamped onto the through hole 11a1, so that the screw indirectly contacts the through hole 11a1 through the washer body 14, realizing soft contact between the first universal connector 12 and the first universal joint 11a, reducing the reversing gap and reducing noise generation. The screw can be extended to pass through other components and is fixedly connected by a nut.

[0060] Reference Figure 4As shown, in some embodiments, the connecting rod 11 further includes: a connecting rod body 111, a first hinge body 112, and a second hinge body 113. One end of the first hinge body 112 is rotatably connected to one end of the connecting rod body 111; the other end of the first hinge body 112 is provided with a first universal hinge portion 11a; and / or one end of the second hinge body 113 is rotatably connected to the other end of the connecting rod body 111; the other end of the second hinge body 113 is provided with a second universal hinge portion 11b. This improves the flexible rotation of the connecting rod 11 to adapt to various transmission requirements. For example, the first hinge body 112 and the second hinge body 113 are respectively threadedly connected to the connecting rod body 111.

[0061] Reference Figure 4 As shown, in some embodiments, the first hinge body 112 includes a through groove 1121 extending through the first hinge body 112, and the inner sidewall of the through groove 1121 is provided with an arc-shaped concave shape. This arc-shaped concave shape is adapted to the first universal joint portion 11a. The curvature of the arc-shaped concave shape matches the spherical surface of the first universal joint portion 11a, ensuring rotational freedom.

[0062] Reference Figure 5 As shown, this embodiment also provides an electrically driven rocking chair 200, including: the aforementioned electric rocking device 100, a fixed bracket 201, a rocking bracket 202, and a swing arm 203.
