[0026] Referring to Figures 1-4, an embodiment of the present invention provides a multi-mode motion rocking chair, including: a base 1, wherein a power mechanism 20 is disposed in the base 1, and further comprising:

[0027] A linkage mechanism, the first end of which is connected to the output end of the power mechanism 20; a sliding chassis 11, which is slidably connected to the base 1, and a rotating support shaft 5 is rotatably inserted into the sliding chassis 11, the rotating support shaft 5 passing through the sliding chassis 11, the first end of the rotating support shaft 5 being rigidly connected to the second end of the linkage mechanism; a seat assembly 8, which is disposed at the end of the sliding chassis 11 away from the linkage mechanism, and the second end of the rotating support shaft 5 is located inside the seat assembly 8; and a mode adjustment component, used to adjust the connection state between the rotating support shaft 5 and the seat assembly 8.

[0028] In this embodiment, the base 1 serves as the basic structure of the rocking chair, and a power mechanism 20 is installed inside. The base 1 and other components achieve coordinated movement through sliding connections. The linkage mechanism consists of an eccentric rod 3 and a drive rod 4. The power mechanism consists of a motor 2, a transmission belt 21, a turbine 22, and a gear 23. The output end of the motor 2 is connected to one end of the transmission belt 21 through a coupling, driving the transmission belt to rotate. The other end of the transmission belt 21 is fitted with a turbine 22, which rotates the gear 23 through the connection thread of the turbine 22 and the teeth of the gear 23. There is a fixed hole at the center point of the gear 23, which serves as the output port of the power mechanism 20. The first end of the eccentric rod 3 is connected to the hole at the center point of the gear 23, and the power mechanism 20 drives the eccentric rod 3 to perform circular motion. The second end of the eccentric rod 3 is vertically and movably connected to the first end of the drive rod 4, converting the circular motion of the eccentric rod 3 into the horizontal motion of the drive rod 4. A sliding base is also included. The sliding base 11 is slidably connected to the base 1, enabling the movement of the entire rocking chair. A rotating support shaft 5 is inserted inside the sliding base 11, and this shaft passes through the sliding base 11. The first end of the rotating support shaft 5 is rigidly connected to the second end of the linkage mechanism. Specifically, the rigid connection can be such that the connection between the first end of the rotating support shaft 5 and the second end of the linkage mechanism is a non-circular contact surface, used for tight engagement and stable connection. This connection can convert the horizontal movement of the drive rod 4 into the reciprocating rotational movement of the rotating support shaft 5. The seat assembly 8 is connected to the end of the sliding base 11 away from the linkage mechanism. The second end of the rotating support shaft 5 is located inside the seat assembly 8. The seat assembly 8 is the part for the user to sit or lie down. The rocking chair movement in different movement modes is realized through the connection with the rotating support shaft 5. The mode adjustment component is used to adjust the connection state between the rotating support shaft 5 and the seat assembly 8. Through the mode adjustment button, the user can adjust the connection method between the rotating support shaft 5 and the seat assembly 8, thereby switching between different movement modes.

[0029] In addition to the rocking motion, optional features include music playback and vibration functions. Music can be played through a built-in music module, providing pleasant auditory stimulation for the baby; while vibration is generated by a vibration device, providing additional sensory stimulation to help the baby relax and fall asleep. In summary, this application provides multiple motion modes, allowing for both linear rocking and reciprocating linear movements, enabling users to choose the appropriate mode based on their needs, increasing flexibility. The connections between components utilize rigid or bearing connections, ensuring the stability and durability of the rocker's movement. This multi-mode rocker offers advantages such as versatility, enhanced comfort, adjustability, stability, and ease of operation, simulating the rocking sensation of a parent's embrace, providing a comfortable experience for the baby. Furthermore, the structural connections described in this application can be used in the design of various rockers, making it suitable for a wide range of scenarios.

[0030] In one embodiment, the linkage mechanism includes an eccentric rod 3 and a drive rod 4; the first end of the eccentric rod 3 is tightly connected to the output end of the power mechanism 20, and the power mechanism 20 drives the eccentric rod 3 to perform circular motion; the second end of the eccentric rod 3 is vertically and movably connected to the first end of the drive rod 4, for converting the circular motion of the eccentric rod 3 into the horizontal motion of the drive rod 4.

[0031] In this embodiment, the eccentric rod 3 is driven by the power mechanism 20 to make circular motion, and the linkage mechanism converts it into horizontal motion of the drive rod 4. The horizontal motion of the drive rod 4 can effectively balance and stabilize the seat, reduce the bumps and vibrations caused by rapid movement, and fully simulate the motion scenario in reality, such as the horizontal rocking of a parent holding a child. This design can bring users a more immersive feeling and experience. Through this connection method, the movement mode of the rocking chair can be adjusted later by changing the speed of the motor 2 and the shape of the eccentric rod 3, such as the frequency of rocking, slow back and forth, etc., to meet the user's needs for different dynamic experiences and maintain a comfortable seat state.

[0032] Multiple fixed eccentric points can be set on the eccentric rod 3, each representing a swing amplitude. Users can choose to install the eccentric rod 3 on different eccentric points to achieve different swing amplitudes. This design provides multiple options to meet the needs of different babies. Alternatively, the length of the eccentric rod 3 can be adjusted, allowing for flexible adjustment within a certain range. Users can change the length of the eccentric rod 3 through a rotation or sliding mechanism, thereby changing the swing amplitude. Another option is to set replaceable eccentric blocks on the eccentric rod 3, each representing a swing amplitude. Users can select and replace the appropriate eccentric block as needed to achieve different swing amplitudes. Since a baby's preferences and needs may change over time, an adjustable rocking speed function can be introduced into the baby rocking chair. Parents can select an appropriate rocking speed according to the baby's preferences and needs to achieve the best relaxation effect.

[0033] Optionally, the connection between the eccentric rod 3 and the drive rod 4 can be a pin connection; specifically, the second end of the eccentric rod 3 has a hole, while the first end of the drive rod 4 has a pin. A pin passes through the fixing hole on the eccentric rod 3 and the fixing hole on the drive rod 4, connecting the two. Pin connection is a simple and reliable connection method, easy to manufacture and install. This connection provides sufficient support and stability, ensuring the accuracy of motion transmission between the eccentric rod 3 and the drive rod 4. Since the pin is connected vertically, it requires very little space, saving space in the design. When maintenance or replacement of parts is needed, the pin connection allows for easy separation of the eccentric rod 3 and the drive rod 4, reducing maintenance time and workload. Alternatively, a sliding connection can be used. Specifically, the second end of the eccentric rod 3 is designed as a raised cylindrical structure, while the first end of the drive rod 4 has a correspondingly shaped groove. By sliding the raised portion into the groove, the eccentric rod 3 and the drive rod 4 are connected. Sliding connection provides smooth movement, reduces friction and resistance, and achieves a tight connection, ensuring no loosening or wobbling between the eccentric rod 3 and the drive rod 4, providing higher stability and guaranteeing the accuracy and safety of the rocking chair's movement. Because sliding connection reduces the contact area and friction, it reduces the possibility of noise generation, providing a quieter and more comfortable user experience.

[0034] In one embodiment, the second end of the drive rod 4 is rigidly connected vertically to the rotating support shaft 5, which is used to convert the horizontal movement of the drive rod 4 into the reciprocating rotational movement of the rotating support shaft 5.

[0035] In this embodiment, the second end of the drive rod 4 is rigidly connected vertically to the rotating support shaft 5. With this connection, when the drive rod 4 moves in the horizontal direction, the rotating support shaft 5 will generate a reciprocating rotational motion, thereby causing the entire rocking chair to generate a corresponding rocking motion. By simulating the gentle rocking in a mother's arms, it provides comfort and soothing, helping the baby relax and fall asleep. At the same time, the rocking motion can promote the development of the baby's sense of balance and motor coordination. The baby rocking chair can provide parents with some valuable free time. When the baby is rocking, parents can have more time to handle other matters or rest, reducing the burden of care.

[0036] In one embodiment, the first end of the rotating support shaft 5 has an irregular cylindrical shape, and the second end of the drive rod is provided with a snap-fit ​​interface that matches the shape of the first end of the rotating support shaft 5.

[0037] In this embodiment, the first end of the rotating support shaft 5 is preferably an irregular cylinder. Alternatively, it can be designed as a cuboid or other non-circular shape. This design makes the connection between the rotating support shaft 5 and the drive rod 4 more stable. When the drive rod 4 moves in the horizontal direction, the rotating support shaft 5 is less likely to slide in the interface when it follows the reciprocating rotational motion, thus improving the stability of the overall structure and the reciprocating motion effect.

[0038] In one embodiment, the mode adjustment component includes a conversion button 6, which is disposed through the outer side wall of the seat assembly 8. A locking pin assembly 7 is abutted against the inner wall side of the conversion button 6. The locking pin assembly 7 is connected to the seat assembly 8 and is connected to the rotation support shaft 5 by force from the conversion button 6.

[0039] In this embodiment, the mode adjustment component includes a conversion button 6, which passes through the outer side wall of the seat assembly 8. One side of the conversion button 6 is located in the internal space. By applying force to the seat latch assembly 7, the latch assembly 7 is pushed, so that it can be connected or disconnected from the rotation support shaft 5. When connected, the rotation support shaft 5 will drive the seat assembly 8 to rotate, causing the seat assembly 8 to produce a reciprocating rotational motion. When disconnected, the seat assembly 8 only follows the sliding assembly to make linear motion through the connection with the sliding chassis 11.

[0040] In one embodiment, the locking pin assembly 7 includes a movable locking block 50 having a first hole and a second hole. The first hole and the second hole are connected. The diameter of the first hole is larger than that of the second hole. The rotating support shaft passes through the first hole or the second hole, and the rotating support shaft is provided with a locking surface. The second hole is adapted to the shape of the rotating support shaft and is used to lock with the rotating support shaft.

[0041] In this embodiment, the locking assembly 7 includes a movable locking block 50 with a first hole and a second hole, which are connected. The diameter of the first hole is larger. When the rotating support shaft 5 is in the first hole, it does not connect with it, ensuring that the rotating support shaft 5 can pass smoothly. Specifically, the part of the rotating support shaft 5 that contacts the movable locking block 50 is provided with a locking surface. There can be multiple locking surfaces to ensure that the part of the rotating support shaft 5 that contacts the movable locking block 50 is non-cylindrical and does not easily slip when in contact with the movable locking block 50. It can also be a non-circular shape such as a rectangle or polygon. At the same time, the size and shape of the second hole are... The shape and size of the rotating support shaft 5 are matched. This design allows for a secure connection between the rotating support shaft 5 and the movable locking block 50, ensuring that the rotating support shaft 5 stays in the required position and does not affect the stability of the seat due to accidental movement. When the locking pin assembly 7 is controlled by the rotating button, the rotating support shaft 5 switches between the first hole position and the second hole position. When the rotating support shaft 5 is in the first hole position, it is not connected to the seat assembly 8, and the rocking chair only rocks in a straight line. When the rotating support shaft 5 is in the second hole position, it is connected to the seat assembly 8, causing the rocking chair to rotate and reciprocate, forming a rocking effect that is both straight and reciprocating.

[0042] In one embodiment, a base support is provided on the base 1 for placing the sliding chassis 11; rollers 9 are provided on opposite sides of the sliding chassis 11; and a sliding rod 10 is provided on the base support to support the sliding of the rollers 9.

[0043] In this embodiment, a base support is provided on the base 1 for placing the sliding chassis 11. Rollers 9 are provided on opposite sides of the sliding chassis 11. A sliding rod 10 is provided on the base support to support the sliding of the rollers 9. Specifically, the base support includes a support platform, which is a partially upward-extending boss located on opposite sides of the upper side of the base support. One end of the sliding rod 10 is fixed to the support platform. At the same time, a protruding support member is also provided on the base to fix the other end of the sliding rod 10. Cooperating with the support platform, the installation of the sliding rod is more stable. This design can realize the connection and support between the base support and the sliding chassis 11, and the base support provides a stable foundation. A sliding base 11 is used to place the sliding base 11, and the rollers 9 of the sliding base 11 can slide back and forth along the slide rod on the base support, so that the entire seat can move and rotate on a smooth surface. Through the matching of the slide rod 10 with the supporting rollers 9, the slide rod 10 provides support and guidance for the movement of the rollers 9. The rollers 9 can slide along the track of the slide rod 10, so that the seat can move and turn smoothly. Preferably, one side is provided with two rollers 9, and each roller 9 is matched with a slide rod 10 at the upper and lower parts. This design can improve the flexibility and controllability of the seat, allowing users to easily move the seat to the desired position. Moreover, the fixed upper and lower slide rods 10 can ensure that the movement trajectory of the rollers 9 is more stable and less prone to displacement or deviation.

[0044] In one embodiment, a bearing is provided at the connection between the sliding chassis 11 and the rotating support shaft 5.

[0045] In this embodiment, a bearing is provided at the connection between the sliding chassis 11 and the rotating support shaft 5. By providing a bearing at the connection, the friction between the base 1 and the support shaft can be reduced, allowing the base 1 to rotate smoothly on the rotating support shaft 5. At the same time, the bearing can withstand a large load and has a low coefficient of friction, thereby reducing the force and resistance required for seat operation and ensuring that the rotating support shaft 5 can rotate while being securely connected to the sliding chassis 11.

[0046] In one embodiment, the bottom of the sliding chassis 11 is a hollow structure, and the linkage mechanism is connected to the rotating support shaft 5 that passes through the sliding chassis 11 in the internal space of the hollow structure.

[0047] In this embodiment, the bottom of the sliding chassis 11 is a hollow structure, and the linkage mechanism is located in the internal space of the hollow structure and connected to the rotating support shaft 5 that runs through the sliding chassis 11. The hollow structure design can provide a larger internal space to accommodate the linkage mechanism and the rotating support shaft 5. This structure can make the chassis lighter and more compact, while providing enough space for the linkage mechanism to move.

[0048] In one embodiment, the power mechanism includes: a motor 2, a transmission belt 21, a turbine 22, and a gear 23; the output end of the motor 2 is connected to one end of the transmission belt 21, the other end of the transmission belt 21 is connected to the turbine, the turbine 22 is threadedly connected to the gear 23 to drive the gear 23 to rotate, and the gear 23 is connected to the first end of the transmission mechanism.

[0049] In this embodiment, the power mechanism consists of a motor 2, a transmission belt 21, a turbine 22, and a gear 23. The output end of the motor 2 is connected to one end of the transmission belt 21 via a coupling, driving the transmission belt to rotate. The other end of the transmission belt 21 is fitted with a turbine 22, which rotates by engaging the teeth of the gear 23 through the connecting thread of the turbine 22. There is a fixed hole at the center point of the gear 23, which serves as the output port of the power mechanism 20. The first end of the eccentric rod 3 is connected to the hole at the center point of the gear 23, and the power mechanism 20 drives the eccentric rod 3 to perform circular motion.
