[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] In the existing rocking chair, people need to move their limbs slightly to drive the rocking chair to swing or rock, so that the rocking chair can rock back and forth, thus affecting people's use experience. Therefore, an automatic rocking chair is proposed to solve the above problem.

[0029] The scheme is further illustrated by the following examples:

[0030] Figure 1 It is a schematic diagram of an automatic rocking chair according to an embodiment of the utility model.

[0031] See also Figure 1 The automatic rocking chair of this embodiment may include a seat 10 and a rocking mechanism. The bottom of the seat 10 may be provided with an arc-shaped seat foot 11, so that the seat 10 can rock along the bottom of the seat foot 11, so that the seat 10 can rock, and the user sitting on the seat 10 can follow the rocking chair to rock, thereby achieving the effect of regulating the body and mind.

[0032] In this embodiment, the swing mechanism is used to drive the seat 10 to swing, so that the seat 10 swings driven by the swing mechanism, so that the rocking chair can swing automatically without user intervention, further improving the user experience.

[0033] See also Figure 1 The swing mechanism may include a driving unit 21, a first link 22, a second link 23 and a third link 24. One end of the first link 22 may be connected to the end of the seat foot 11, the other end of the first link 22 may be hinged to the end of the second link 23, the end of the second link 23 away from the first link 22 may be hinged to the third link 24, and one end of the third link 24 may be fixedly connected to the driving unit 21. Therefore, the driving unit 21 can drive the third link 24 to rotate, and the third link 24 can drive the seat 10 to swing through the second link 23 and the first link 22.

[0034] In addition, the sum of the lengths of the second link 23 and the third link 24 is less than the length of the first link 22, and the length of the second link 23 is greater than the length of the third link 24, so that the third link 24 can rotate under the drive of the driving unit 21, and avoid mechanical self-locking between the first link 22, the second link 23 and the third link 24, thereby ensuring that the driving unit 21 can drive the third link 24, the second link 23, the first link 22 and the seat 10 to move continuously.

[0035] It should be noted that since the third link 24 is fixed at the output end of the drive unit 21, and the rotation radius of the end of the third link 24 away from the drive unit 21 is the length of the third link 24 itself, when the length of the second link 23 is greater than the length of the third link 24, when the third link 24 rotates under the drive unit 21, it can drive the second link 23 and the first link 22 to move within a smaller rotation range, so that the seat 10 swings within a smaller range, thereby preventing the seat 10 from tipping over during the swinging process.

[0036] Figure 2 yes Figure 1 Another schematic diagram of an automatic rocking chair.

[0037] See also Figure 2 The third connecting rod 24 may be provided with a hinge portion 241. The hinge portion 241 is used to be hinged with the second connecting rod 23 so that the third connecting rod 24 and the second connecting rod 23 can rotate relative to each other.

[0038] In this embodiment, a plurality of hinged portions 241 may be provided, and the plurality of hinged portions 241 are arranged along the length direction of the third link 24. The end of the second link 23 may be selectively connected to the hinged portion 241 on the third link 24, so that by adjusting the connection between the second link 23 and the hinged portion 241, the connection position of the second link 23 and the third link 24 is adjusted, and the rotation radius between the second link 23 and the driving unit 21 is adjusted.

[0039] It should be noted that the distance between the connection position of the second link 23 and the third link 24 and the rotation center of the driving unit 21 can be considered as the rotation radius of the end of the second link 23, which can affect the swing amplitude of the first link 22 and the seat 10. Therefore, by adjusting the connection position between the second link 23 and the third link 24, the swing amplitude of the seat 10 can be adjusted, that is, the second link 23 is connected to different hinge parts 241, which can drive the seat 10 to swing with different amplitudes, thereby meeting the use needs of different users.

[0040] See also Figure 1 The drive unit 21 may be provided with a controller and a drive motor. The controller is electrically connected to the drive motor and is used to control the opening or closing of the drive motor. At the same time, the controller has a timing function to control the closing or opening of the control motor within a predetermined time.

[0041] The output end of the driving motor can be fixedly connected to the end of the third connecting rod 24 to drive the third connecting rod 24 to rotate. It should be noted that the length direction of the third connecting rod 24 is perpendicular to the rotation axis of the driving motor, so that the third connecting rod 24 can drive the second connecting rod 23 to move, and the connection position between the second connecting rod 23 and the third connecting rod 24 can be adjusted to adjust the rotation radius of the second connecting rod 23.

[0042] In this embodiment, a rotation bearing is provided at one end of the first connecting rod 22 away from the base 11, and the first connecting rod 22 is hinged to the second connecting rod 23 through the rotation bearing. At the same time, a rotation bearing is provided at the end of the second connecting rod 23, that is, both ends of the second connecting rod 23 are provided with rotation bearings, and the second connecting rod 23 is hinged to the first connecting rod 22 and the second connecting rod 23 through the rotation bearing. In addition, a rotation bearing is provided at one end of the third connecting rod 24 away from the driving unit 21, and the third connecting rod 24 is hinged to the second connecting rod 23 through the rotation bearing. The connection between the first connecting rod 22, the second connecting rod 23 and the third connecting rod 24 is provided with a rotation bearing, which can improve the rotation efficiency between the two connecting rods at the connection and avoid wear of the connection between the two connecting rods during rotation.

[0043] It should be noted that the first link 22, the second link 23 and the third link 24 are all metal links, so that the first link 22, the second link 23 and the third link 24 can have a certain structural strength, thereby ensuring that the drive unit 21 can drive the seat 10 and the user sitting on the seat 10 to swing together through the first link 22, the second link 23 and the third link 24.

[0044] Of course, in some other embodiments, the first connecting rod 22, the second connecting rod 23 and the third connecting rod 24 can also be set as plastic connecting rods or wooden connecting rods, etc., so that the driving unit 21 can drive the seat 10 to swing through the first connecting rod 22, the second connecting rod 23 and the third connecting rod 24.

[0045] Figure 3 , Figure 4 and Figure 5 yes Figure 1 Schematic diagram of different motion states of an automatic rocking chair. Figure 6 yes Figure 1 Schematic diagram of the movement principle of the automatic rocking chair.

[0046] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 When the seat 10 is in a horizontal state, the positions of the first link 22, the second link 23 and the third link 24 are as follows: Figure 1When the driving motor drives the third connecting rod 24 to rotate counterclockwise, the seat 10 swings backwards under the linkage of the second connecting rod 23 and the first connecting rod 22 until the seat 10 is in the state of being ... Figure 3 When the driving motor continues to drive the third connecting rod 24 to continue rotating, the seat 10 swings forward and can rotate to Figure 4 When the driving motor continues to drive the third link 24 to continue to rotate, the seat 10 continues to swing forward and drives the seat 10 to rotate to the horizontal state. Figure 5 When the driving motor continues to drive the third connecting rod 24 to continue to rotate, the seat 10 swings backward and drives the seat 10 to rotate to the forward tilted position. Figure 1 At this point, the seat 10 completes a swing cycle.

[0047] In addition, see Figure 6 , circle 242 is the rotation trajectory of the connection between the third link 24 and the second link 23, and the radius of circle 231 is the distance from the hinge of the second link 23 and the first link 22 to the hinge of the second link 23 and the third link 24. Since the movement of the second link 23 is subject to the first link 22 and the third link 24, under ideal conditions, the movement trajectory of the hinge of the first link 22 and the second link 23 can be considered as arc 221, that is, the swing arc and swing range of the seat 10 and the first link 22 are arc 221. Therefore, driven by the driving unit 21 through the third link 24 and the second link 23, the seat 10 and the first link 22 can automatically swing, and self-locking is generated between the first link 22, the second link 23 and the third link 24.

[0048] See also Figure 2 The first connecting rod 22 is fixedly connected to the seat foot 11 by a screw 31. In this embodiment, a plurality of screws 31 may be provided, so that the end of the first connecting rod 22 can be fixedly connected to the seat foot 11 by a plurality of screws 31.

[0049] It should be noted that the connection between the first link 22 and the seat foot 11 should be set at the end of the seat foot 11, so that the second link 23 can drive the first link 22 and the seat 10 to swing with a smaller driving force. Specifically, since the seat foot 11 is arc-shaped, the seat 10 generally swings around the bottom of the seat foot 11. Therefore, when the first link 22 is connected to the end of the seat foot 11, the swinging torque can be increased, thereby reducing the driving force of the second link 23 to drive the first link 22 and the seat 10 to swing.

[0050] It should be noted that the automatic rocking chair may further include a buckle. The buckle is fixed to one end of the first connecting rod 22 facing the seat foot 11, and the first connecting rod 22 is detachably connected to the seat foot 11 through the buckle. That is, the buckle is provided with a buckle structure, which can be clamped on the outer side of the seat foot 11, so that the first connecting rod 22 can be fixedly connected to the seat foot 11. In this embodiment, the buckle can be provided as a sleeve matching the outer peripheral side of the seat foot 11, and the sleeve can be sleeved and fixed on the outer peripheral side of the seat foot 11.

[0051] See also Figure 2 The automatic rocking chair may further include an anti-rolling member 32. The anti-rolling member 32 is connected to the end of the rear side of the seat foot 11 to abut between the seat foot 11 and the ground, and limit the range of the seat 10 to swing backward. During the use of the seat 10, since the user generally lies on the backrest of the seat 10, the center of gravity changes. In the process of the swing mechanism driving the seat 10 to swing, if the swing amplitude is too large, it is easy to cause the seat 10 to tip backward, thereby causing harm to the user. Therefore, the anti-rolling member 32 is provided at the rear end of the seat foot 11, which can ensure that the seat 10 swings within a specific amplitude or range, thereby ensuring the safety of the swinging of the seat 10.

[0052] In summary, since the bottom of the seat 10 is provided with an arc-shaped foot 11, the seat 10 can swing along the bottom of the foot 11. Therefore, the driving unit 21 can drive the seat 10 and the first link 22 to swing automatically through the third link 24 and the second link 23, thereby improving the user experience.

[0053] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive.
