[0042] Now refer to the appendix Figures 1-19 Embodiments of the present invention are described.

[0043] A children's rocking chair, characterized in that it includes a seat, a support frame, and a seat limiting mechanism. The support frame includes a base and a drive mechanism. The drive mechanism includes a drive motor, a drive motor power output unit, a rotating shaft, and a mounting box. One end of the rotating shaft is fixedly connected to the drive motor power output unit, and the other end of the rotating shaft is pivotally connected to the seat. When the rotating shaft rotates, the pivot point between the other end of the rotating shaft and the seat moves relative to the fixed point between the one end of the rotating shaft and the drive motor power output unit. The drive motor and the drive motor power output unit are mounted on the mounting box, which is fixedly connected to the base. The seat limiting mechanism includes a drive component and a drive mating component. When the rotating shaft rotates, the mating point between the drive component and the drive mating component moves relative to the support frame. The seat limiting mechanism ensures that the angle between the seat and the rotating shaft is maintained at a set angle when the drive motor drives the rotating shaft. The seat is used to carry a child.

[0044] To provide consumers with more entertainment, a seat limiting mechanism for a children's rocking chair also includes a swing mode conversion unit, which can realize at least two swing modes.

[0045] The oscillation mode conversion unit includes a drive unit. The drive unit drives the drive component and the drive mating component to cooperate, and the resulting point forms a motion trajectory line that includes at least two different motion trajectory lines. This enables the conversion of at least two oscillation modes.

[0046] The drive unit includes an electric drive unit, a drive component and a drive mating component that are configured to rotate or move a distance relative to the support frame. When the rotating shaft rotates, the drive unit drives the drive mating component to rotate or move a distance relative to the support frame, thereby achieving at least two swing modes. The electric drive unit enables automatic switching between at least two modes, eliminating the need for manual operation, making it more intelligent and appealing to consumers.

[0047] The driving component is a moving part, and the driving mating part is a moving slot. The moving slot is pivotally connected to the support frame. The driving unit includes a drive motor assembly, which includes a motor, a rotating part, and an output part. The motor is fixedly connected to the rotating part, the rotating part is pivotally connected to the output part, and the output part is pivotally connected to the moving slot. The rotation of the rotating shaft drives the drive motor assembly, causing the moving slot and the support frame to continuously reciprocate relative to each other. Each swing mode can be determined by the angle of rotation of the driving mating part relative to the support frame or the length of the distance traveled, or by the speed at which the driving unit drives the driving mating part to rotate or travel distance relative to the support frame. All of these determining factors can be controlled by the circuit control board. As long as multiple swing modes are set and the switching between multiple swing modes is set, the circuit control board will intelligently control them, greatly reducing the tediousness of manual operation required for each swing mode switch. At the same time, it overcomes the high cost and limited swing mode variety of mechanical switching, making operation convenient and enriching the consumer's entertainment experience.

[0048] The drive unit includes a locking and unlocking mechanism. The drive member and the drive mating member are configured to move apart. The drive mating member is rotatable or movable apart relative to the support frame. After the drive mating member is unlocked and rotated or moved apart relative to the support frame, the drive mating member locks with the support frame. The drive mating member then engages with the drive member to form another swing mode.

[0049] The driving component is a moving component, and the driving mating component is a moving groove, including at least two moving grooves: a first moving groove and a second moving groove. The openings of the first and second moving grooves do not overlap. The moving grooves are vertically movable relative to the support frame. When the first moving groove mates with the first moving component, it is in the first swing mode; when the second moving groove mates with the second moving component, it is in the second swing mode. When the moving grooves move vertically relative to the support frame, the first and second moving grooves alternately mate with the moving component, thereby achieving the switching between the two swing modes. This design has the advantages of simple structure, convenient operation, and low cost.

[0050] The driving component is a movable component, and the driving mating component is a movable groove. The movable groove is movable relative to the support frame along the swing direction of the rotation axis. The movement of the movable groove relative to the support frame changes the interaction between the movable groove and the movable component to form different swing modes. It is easy to operate and has a simple structure.

[0051] The moving parts include at least two moving parts, namely a third moving part and a fourth moving part. The moving slots also include at least two moving slots, namely a third moving slot and a fourth moving slot. The third moving part mates with the third moving slot, and the fourth moving part mates with the fourth moving slot. One moving slot has an exit opening for the moving part to move out, and the other has an entry opening for the moving part to move in. The widths of the exit and entry openings are greater than the width of the moving slot. Using two moving parts and two moving slots overcomes the drawback of uneven oscillation caused by a single moving part and moving slot when a specific rotation mode is required. When the third moving part mates with the third moving slot, the fourth moving part does not mate with the fourth moving slot, thus avoiding interference. When the third moving part moves out of the third moving slot, the fourth moving part mates with the fourth moving slot. Therefore, by different settings for the third moving slot, various oscillation modes are enriched without causing uneven oscillation. The non-overlapping openings of the third and fourth moving slots are precisely what allows for the rich variety of oscillation modes.

[0052] The moving slot is equipped with a stop block, and the moving part is equipped with a rotating part. When one side of the seat is subjected to gravity, the moving part will move to the top. The stop block restricts the rotating part, thus preventing the seat from tilting when subjected to gravity and ensuring the safety of consumers.

[0053] The movable component is mounted on the base, and the movable slot is mounted on the support frame. This is just a more reasonable structural arrangement; of course, the movable component could also be mounted on the support frame, and the movable slot on the base.

[0054] The moving groove can be an arc-shaped groove or a wave-shaped groove with alternating heights. The moving groove can have various shapes. The shape of the moving groove determines the angle between the seat and the rotating shaft. Many shapes can be selected according to the needs. For example, if the moving groove is an arc-shaped groove, after the rotating shaft rotates, the seat moves with the rotating shaft and the angle between the seat and the rotating shaft remains unchanged. Therefore, an arc-shaped groove or a wave-shaped groove with alternating heights is the preferred solution.

[0055] A rotating component is provided on the moving component, which can rotate around the moving component and mates with the surface of the moving groove. The rotating component reduces friction when the moving component moves with the moving groove. In this embodiment, the rotating component is a bearing.

[0056] The drive mechanism also includes sensors mounted on the drive motor, which is connected to a reduction gear set. The sensors control the drive motor to continuously reciprocate in both directions, thus causing the rotating shaft to continuously reciprocate in both directions. By detecting the rotation angle of the rotating shaft and the forward and reverse rotation of the drive motor through the sensors, the movement distance of the base is controlled. The reduction gear set reduces speed and increases force, resulting in a simple structure and low cost. The tilted setting of the rotating shaft can generate a conversion between kinetic and potential energy, thereby achieving labor saving.

[0057] The device includes a drive mounting box and a moving part consisting of an upper and a lower end. The upper and lower ends are fixedly connected or integrally formed. The upper end passes through the drive mounting box and connects to the base body, while the lower end mates with a moving slot. The connection point between the upper end and the base body is offset from the mating point between the lower end and the moving slot. The upper end of the moving part and the slot in the drive mounting box are located in the middle of the drive mounting box, reducing the cost of covering the slot and decreasing the size. The offset of the mating point from the connection point generates torque, making the swinging motion less smooth.

[0058] The mounting box is equipped with a slotted plate, which is movably mounted on the mounting box. The slotted plate also has a slot for a movable component to move. When the movable component moves, it drives the slotted plate to block the slot. The movable component also drives the slotted plate to rotate around the mounting box. By rotating the plate up and down within the slot through the rotating shaft, the slotted plate achieves an arc shape. This allows the slotted plate to cover the movable slot while maintaining a small size, thus ensuring that it does not pinch fingers and making the mounting box smaller, more aesthetically pleasing, and cost-effective.

[0059] This invention provides a children's rocking chair with a large swing amplitude, low cost, stable seat, and simple structure. It can be set to two or more different swing modes, overcoming the shortcomings of existing rocking chairs on the market that have small swing amplitudes, high manufacturing requirements, and can only swing in a single mode. This invention features a simple structure, low cost, a stable seat, and the ability to simultaneously achieve two different swing modes, as well as the ability to switch between multiple swing modes. It was invented through long-term, meticulous research by engineers and is not something easily conceived by those skilled in the art, nor is it common knowledge. The terms "one end" and "other end" used in this invention are merely descriptive terms and can be understood as either the top of something or a segment of something.

[0060] Although the present invention has been described above with reference to embodiments, various modifications can be made to it without departing from the scope of the invention, and the invention can be implemented in other equivalent or well-known ways by those skilled in the art. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims. The terms "first," "second," "third," and "fourth" used herein are merely for distinguishing names and have no actual data meaning.
