[0002] With the development of technology and the improvement of people's living standards, electric furniture is increasingly entering daily life, improving people's comfort and quality of life.

[0003] To meet the needs of soothing infants to sleep, an electric rocking chair is provided in the prior art. It includes a base frame, a seat frame, and a rocking mechanism connecting the base frame and the seat frame. The rocking mechanism includes a drive component, a connecting seat slidably mounted on the base frame, and a transmission assembly connecting the drive component and the connecting seat. The connecting seat has a groove. The transmission assembly includes a gear driven to rotate by the drive component with its axis extending vertically, and a connecting rod with one end fixedly connected to the gear. The other end of the connecting rod is inserted into the groove. When the gear rotates, causing the center of the connecting rod seat to move, the other end of the connecting rod moves linearly within the groove, pushing the groove to cause the connecting seat to reciprocate on the base frame, thereby causing the seat frame connected to the connecting seat to swing back and forth.

[0004] The existing electric rocking chairs use a drive mechanism to slide the connecting seat through a transmission assembly to achieve the back-and-forth swinging of the seat frame. The entire rocking mechanism is complex and occupies a large space, resulting in higher cost and weight for the electric rocking chairs. Utility Model Content

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] like Figures 1 to 3 As shown, this embodiment provides an electric rocking chair, which includes a base frame 200, a support frame 300, and a rocking mechanism 100 connected between the base frame 200 and the support frame 300. The support frame 300 can swing back and forth relative to the base frame 200 through the rocking mechanism 100, so as to meet the rocking needs of the user on the support frame 300, while simplifying the structure of the electric rocking chair and reducing the cost and weight of the electric rocking chair.

[0050] Specifically, the swing mechanism 100 provided in this embodiment includes a mounting base 3, a swing seat 2, and a swing drive assembly 1. The swing seat 2 is rotatably mounted on the mounting base 3 around a first axis, and the swing seat 2 reciprocates on the mounting base 3 between a first position and a second position. The swing drive assembly 1 includes a drive member 11 and an elastic reset member 12. The first end of the elastic reset member 12 is mounted on the mounting base 3, and the elastic reset member 12 is connected to and linked with the swing seat 2. The drive member 11 is disposed on the mounting base 3 and cooperates with the elastic reset member 12. Under the action of the external force of the drive member 11, the elastic reset member 12 deforms and moves to drive the swing seat 2 to swing toward the second position. After the external force of the drive member 11 is removed, the rebound force accumulated by the deformation of the elastic reset member 12 drives the swing seat 2 to reset and move toward the first position. The base frame 200 is connected to the mounting base 3, and the swing seat 2 is connected to the support frame 300.

[0051] The rocking mechanism 100 provided in this embodiment enables the rocking seat 2 to repeatedly swing relative to the mounting base 3 at a first position and a second position via the rocking drive assembly 1, thereby realizing the rocking of the rocking seat 2 and thus enabling the electric rocking chair using the rocking mechanism 100 to automatically swing. At the same time, since the rocking drive assembly 1 uses the action of the driving elastic reset member 12 to realize the linkage swing of the rocking seat 2 to the second position, and the deformation recovery of the elastic reset member 12 drives the rocking seat 2 to return to the first position, the structure of the rocking drive assembly 1 can be effectively simplified, the footprint of the rocking drive assembly 1 can be reduced, the weight and cost of the rocking drive assembly 1 can be reduced, and the performance of the rocking mechanism 100 can be improved.

[0052] The electric rocking chair provided in this embodiment, by adopting the aforementioned rocking mechanism 100, simplifies the structure of the electric rocking chair, reduces the processing and assembly costs of the electric rocking chair, lightens the weight of the electric rocking chair, and improves the performance of the electric rocking chair.

[0053] In this embodiment, the base frame 200 includes a first frame 201 and a second frame 202. The first frame 201 has a U-shaped structure with its opening facing upwards and backwards, and the second frame 202 has a U-shaped structure with its opening facing upwards and forwards. The two ends of the U-shape of the first frame 201 and the second frame 202 are connected to each other. The bottom of the U-shape of the first frame 201 and the second frame 202 is supported on the ground, so that the base frame 200 forms a structure with low ends and a high middle, which facilitates the placement of the electric rocking chair on the ground. Furthermore, the two ends of the first frame 201 are hinged to the two ends of the second frame 202, with the hinge axis arranged in the left-right direction, so that the first frame 201 and the second frame 202 can be folded together from both ends to the middle, realizing the folding and storage of the electric rocking chair.

[0054] The support frame 300 includes two support side rods that are opposite to each other in the left and right directions and spaced apart, and a support end rod connecting the two ends of the two support side rods. The support side rods are arc-shaped rod structures with openings facing forward and upward, so as to improve the riding comfort of the electric rocking chair.

[0055] It is worth noting that the structures of the base frame 200 and the support frame 300 described above are exemplary structures, and existing structures applicable to electric rocking chairs can be applied to this embodiment.

[0056] To improve the swing stability of the support frame 300, a swing mechanism 100 is installed on each of the opposite sides of the support frame 300 along the width direction. This stabilizes the force on both sides of the support frame 300 along the width direction, reduces the force borne by a single swing mechanism 100, lowers the driving force requirement for a single drive component 11, and improves the stability and reliability of the swing mechanism 100. Specifically, a swing mechanism 100 is installed on both the left and right sides of the first frame 201. In other embodiments, the swing mechanism 100 may also be located in the middle of the base frame 200 along the width direction.

[0057] Furthermore, the swing mechanism 100 is located in the middle of the base frame 200 along the length direction (i.e., the front-to-back direction) to improve the stability of the rotation of the support frame 300. At the same time, it provides more space for the swing mechanism 100 and reduces the driving force required for the swing mechanism 100 to drive the swing seat 2 to swing.

[0058] Mounting base 3 is installed on the lower side of base frame 200. The upper end of swing base 2 passes through base frame 200 and connects to support frame 300. This means that most of the structure of swing mechanism 100 is located on the lower side of mounting base 3, thereby reducing the probability of interference between swing mechanism 100 and support frame 300 and improving the ease of setting up swing mechanism 100. At the same time, this arrangement can reduce the gap between base frame 200 and support frame 300 and improve structural compactness.

[0059] Specifically, mounting holes are provided on the left and right sides of the first frame 201, and the mounting holes extend along the length of the corresponding side of the first frame 201. The upper end of the mounting base 3 passes through the mounting hole and is connected to the support side rod of the support frame 300.

[0060] like Figures 2 to 5 As shown, in this embodiment, the elastic reset member 12 also has a second end opposite to the first end, and the driving member 11 is disposed close to the second end. The connection position between the elastic reset member 12 and the rocker seat 2 is located between the first end and the second end. The driving member 11 drives the second end of the elastic reset member 12 to rise relative to the first end, so as to realize the rotation of the elastic reset member 12 around the first axis, thereby driving the support frame 300 to swing. Thus, the convenience of the driving member 11 driving the elastic reset member 12 can be improved, the driving force of the driving member 11 driving the elastic reset member 12 to move faster can be reduced, and it is also beneficial to control the swing amplitude of the support frame 300 and improve the rationality of the structural layout.

[0061] In other embodiments, the elastic reset member 12 has a second end disposed opposite to the first end, the connection position of the elastic reset member 12 and the rocker seat 2 is located between the first end and the second end, and the action position of the drive member 11 on the elastic reset member 12 is located between the first end and the second end of the elastic reset member 12.

[0062] The distance between the connection point of the elastic reset member 12 and the rocker seat 2 and the first end is less than the distance between the connection point and the driving member 11. This facilitates control over the swing amplitude of the rocker seat 2 while avoiding structural processing and design difficulties caused by the driving member 11 driving the second end of the elastic reset member 12 to swing too small an amplitude, thus improving the convenience of structural setup. In other embodiments, the relationship between the distance between the connection point of the elastic reset member 12 and the rocker seat 2 and the first end and the distance between the connection point and the driving member 11 can be set according to requirements.

[0063] To improve the ease of setting up the elastic reset member 12, the elastic reset member 12 includes a torsion spring. The torsion spring includes a winding portion 123 and a first spring arm portion 121 connected to one end of the winding portion 123. The other end of the winding portion 123 is fixedly disposed relative to the mounting base 3. The first spring arm portion 121 is connected to the rocker seat 2, and the connection position is spaced apart from the winding portion 123. The driving member 11 drives the first spring arm portion 121 to sway and deform relative to the winding portion 123. Thus, through the swaying and deformation of the first spring arm portion 121, the rocker seat 2 is moved to the second position and elastic force is accumulated. Then, the torsion spring reset action drives the rocker seat 2 back to the first position. By setting the elastic reset member 12 as a torsion spring, the difficulty of setting up the elastic reset member 12 can be reduced, which is conducive to the installation and use of the elastic reset member 12. At the same time, setting the elastic reset member 12 as a torsion spring is conducive to more precise control of the swing amplitude of the rocker seat 2.

[0064] In other embodiments, the elastic reset member 12 may also adopt other structures. For example, the elastic reset member 12 adopts a spring structure. The first end of the spring structure is fixedly installed on the mounting base 3, and the driving member 11 acts on the second end of the spring structure so that the spring structure deforms under the driving action of the driving member 11. The connection position between the elastic reset member 12 and the rocking base 2 is located between the first end and the second end of the spring structure.

[0065] To improve the ease of installation of the elastic reset member 12, a mounting shaft 4 is provided on the mounting base 3. The rocker seat 2 is rotatably connected to the mounting base 3 via the mounting shaft 4. The winding part 123 is sleeved on the mounting shaft 4, and the axis of the mounting shaft 4 is the first axis. By providing the mounting shaft 4, the elastic reset member 12 can be installed on the mounting base 3, and the rocker seat 2 can be rotatably connected to the mounting base 3. This facilitates the control of the fixing point of the elastic reset member 12 during deformation and the rotation axis of the rocker seat 2, improves the reliability of the movement of the elastic reset member 12 and the rocker seat 2, and enhances the structural compactness.

[0066] Furthermore, the mounting base 3 has a mounting cavity, the swing drive assembly 1 is installed in the mounting cavity, and the mounting shaft 4 is installed on one side wall of the mounting cavity. The winding part 123 is clamped between the mounting base 3 and the swing base 2 to prevent the torsion spring from loosening out of the mounting shaft 4 and improve the ease of setting the elastic reset member 12.

[0067] The elastic reset member 12 also includes a second spring arm 122 connected to the other end of the winding portion 123. The second spring arm 122 is opposite to and spaced apart from the first spring arm 121. The second spring arm 122 is fixedly disposed relative to the mounting base 3. The driving member 11 is partially located between the first spring arm 121 and the second spring arm 122, and drives the first spring arm 121 to open relative to the second spring arm 122. By providing the second spring arm 122, the ease of setting the elastic reset member 12 can be improved, which is conducive to the fixed setting of the first end of the elastic reset member 12 relative to the mounting base 3, and ensures the reliability of the elastic reset member 12. In other embodiments, the elastic reset member 12 may not have the second spring arm 122, and the other end of the winding portion 123 may be directly connected to the mounting base 3.

[0068] To improve the rationality of the layout, in this embodiment, the first spring arm 121 is spaced above the second spring arm 122, and the second spring arm 122 extends approximately in the horizontal direction. This allows the length of the first spring arm 121 to be maintained while reducing the size of the swing mechanism 100 in the height direction, thereby facilitating the installation of the swing mechanism 100 on the base frame 200.

[0069] To improve the ease of connection between the elastic reset member 12 and the rocker seat 2, in this embodiment, the rocker mechanism 100 further includes a linkage member 13. The linkage member 13 is connected to both the first spring arm 121 and the rocker seat 2, and is spaced between the drive member 11 and the first end of the elastic reset member 12. Furthermore, the linkage member 13 is located between the first spring arm 121 and the second spring arm 122, thereby utilizing the space between the first spring arm 121 and the second spring arm 122, improving the structural compactness of the rocker mechanism 100, and reducing the height dimension of the rocker mechanism 100. In other embodiments, the linkage member 13 may also be connected to the upper side of the first spring arm 121.

[0070] In this embodiment, the linkage 13 includes a first shaft portion 131 and a second shaft portion 132 coaxially connected. The outer diameter of the second shaft portion 132 is larger than the outer diameter of the first shaft portion 131. The first shaft portion 131 is rotatably mounted on the rocker seat 2, and the axis of the first shaft portion 131 is parallel to the axis of the mounting shaft 4. The second shaft portion 132 is connected to the first spring arm portion 121. This structural design of the linkage 13 improves the convenience of connecting the linkage 13 to the rocker seat 2 and the first spring arm portion 121.

[0071] In other embodiments, the linkage 13 may also adopt other structural settings, as long as the linkage 13 is connected to the first spring arm 121 and the rocker seat 2.

[0072] To improve the ease of setting up the drive component 11, in this embodiment, the drive component 11 includes a drive motor 111 mounted on the mounting base 3 and a cam structure 112 connected to the drive shaft of the drive motor 111. The cam structure 112 rotates with the drive motor 111, causing the elastic reset member 12 to move and deform to store force. This arrangement allows the elastic reset member 12 to swing by driving the cam structure 112 through the drive motor 111. The structure is simple, occupies less space, and helps to improve the overall structural compactness of the swing mechanism 100, simplifying the structure of the swing mechanism 100. Specifically, the cam structure 112 abuts against the first spring arm 121 and drives the first spring arm 121 to swing relative to the winding portion 123.

[0073] In other embodiments, the drive member 11 can also adopt other structures capable of driving the elastic reset member 12 to move and deform. For example, the drive member 11 can also adopt a wax motor, an existing small linear motor, or other structures. Specifically, the cam structure 112 includes a mounting plate portion 1121 and an eccentric shaft portion 1122. The drive shaft and the eccentric shaft portion 1122 are connected to opposite sides of the mounting plate portion 1121. The axis of the drive shaft, the axis of the eccentric shaft portion 1122, and the first axis are all parallel and spaced apart. The eccentric shaft portion 1122 cooperates with the elastic reset member 12. Thus, when the drive shaft rotates around its axis, the height position of the eccentric shaft portion 1122 changes, thereby pushing the end of the first spring arm portion 121 away from the surrounding portion to rise when the eccentric shaft portion 1122 rises; when the height of the eccentric shaft portion 1122 falls, the first spring arm portion 121 resets under the action of the accumulated elastic force. Specifically, the eccentric shaft portion 1122 is located between the first spring arm portion 121 and the second spring arm portion 122.

[0074] To improve the ease of installation and disassembly of the swing drive assembly 1, the mounting base 3 includes a first base 31 and a second base 32 that are fastened together. The first base 31 and the second base 32 form a mounting cavity, within which the swing drive assembly 1 is located. A clearance opening is formed at the upper ends of the first base 31 and the second base 32, through which the swing seat 2 is movably inserted. Both the drive component 11 and the swing seat 2 are mounted on the first base 31. This arrangement facilitates the disassembly and maintenance of the internal structure of the mounting base 3 by assembling and disassembling the second base 32 relative to the first base 31, thereby improving the ease of disassembly and maintenance of the swing mechanism 100. Simultaneously, since both the drive component 11 and the swing seat 2 are mounted on the first base 31, the swing drive assembly 1 remains connected to both the mounting base 3 and the swing seat 2 when the second base 32 is disassembled, allowing for better disassembly and maintenance of the swing drive assembly 1. Specifically, the first base 31 and the second base 32 are fastened together in the left-right direction.

[0075] The rocker seat 2 includes a main seat body 21 and a connecting plate 22. The lower sides of both the main seat body 21 and the connecting plate 22 extend into the mounting base 3, and the connecting plate 22 is rotatably connected to the mounting base 3. The upper side of the rocker seat 2 extends out of the mounting base 3. By extending the upper side of the rocker seat 2 out of the mounting base 3, it is easier to connect the rocker seat 2 to the support frame 300. At the same time, by setting the connecting plate 22 to the mounting base 3 for rotation, the connection between the rocker seat 2 and the mounting base 3 can be improved, and the space occupied by the connecting part of the rocker seat 2 in the mounting cavity can be reduced, thereby improving the overall structural compactness of the rocker mechanism 100 and reducing interference between structures. The connecting plate 22 is perpendicular to the first axis.

[0076] The upper end of the rocker seat 2 has a limiting part 211, which is located on the upper outer side of the mounting base 3. The width of the limiting part 211 is greater than the width of the clearance opening, thereby restricting the limiting part 211 from being inserted into the mounting cavity through the clearance opening, thus better ensuring the rocker stability and reliability of the rocker seat 2. At the same time, this arrangement can reduce the size of the clearance opening while increasing the size of the upper end of the rocker seat 2, thereby enhancing the overall structural strength and rigidity of the rocker seat 2 and improving the connection stability and reliability between the rocker seat 2 and the support frame 300. Specifically, the limiting part 211 is located at the upper end of the main body 21.

[0077] Furthermore, the main body 21 includes a seat plate portion 212 on the lower side of the connecting and limiting portion 211. The seat plate portion 212 and the connecting plate 22 are arranged side by side in the front-rear direction, and the seat plate portion 212 is located on the side of the connecting plate 22 away from the rocking drive assembly 1. The seat plate portion 212 is inserted into the mounting base 3. This arrangement can reduce the space occupied by the lower end of the rocking seat 2 in the mounting base 3.

[0078] Furthermore, the connecting plate 22 and the main seat 21 are detachably connected, which helps to reduce the processing difficulty of the rocker seat 2 and facilitates the individual replacement of the connecting plate 22 and the main seat 21. In other embodiments, the connecting plate 22 and the main seat 21 can also be integrally formed or welded.

[0079] To improve the ease of connection between the connecting plate 22 and the main body 21, a positioning slot is provided on the lower side of the main body 21, and the upper side of the connecting plate 22 is inserted into the positioning slot to achieve assembly and positioning of the two. The connecting plate 22 and the main body 21 are connected by fasteners that pass through them to ensure the stability of the connection.

[0080] The connecting plate 22 includes a main plate portion 221, the upper end of which is connected to the main seat body 21, and a protruding plate portion 222 is provided at the lower end of the main plate portion 221. The main plate portion 221 is located on the upper side of the cam structure 112, and the protruding plate portion 222 is connected to the mounting shaft 4 and the linkage member 13. This achieves the connection of the connecting plate 22 with the linkage member 13 and the mounting shaft 4, while avoiding interference between the connecting plate portion 22 and the driving member 11.

[0081] To further improve the reliability of the rocker seat 2 swinging between the first and second positions, the mounting base 3 is provided with a first support component 311a. The first support component 311a is spaced apart from the elastic reset component 12. When the rocker seat 2 is in the first position, the rocker seat 2 is supported by the first support component 311a, which can ensure that the rocker seat 2 can be stable in the first position, avoid the rocker seat 2 from swinging too far, and improve the reliability of the rocker seat 2 swinging to the first position.

[0082] The mounting base 3 has a second support component 311b inside, which is spaced apart from the elastic reset component 12. When the rocking seat 2 is in the second position, the rocking seat 2 is supported by the second support component 311b. By setting the second support component 311b, the rocking seat 2 can be stably positioned in the second position, improving the comfort of the electric rocking chair. Furthermore, the contact between the rocking seat 2 and the second support component 311b limits the rocking seat 2 from continuing to swing in a direction away from the first position, improving the rocking reliability of the rocking seat 2.

[0083] In this embodiment, a fixing post 311 protrudes from the cavity wall of the first seat 31 toward the second seat 32. The first seat 31 and the second seat 32 are connected by fasteners passing through the first seat 31 and the fixing post 311. Multiple fixing posts 311 are provided inside the first seat 31 to ensure connection stability and reliability. One fixing post 311 forms a first support member 311a, and another fixing post 311 forms a second support member 311b. This simplifies the structure of the mounting base 3 and reduces the processing difficulty of the mounting base 3.

[0084] A control board 5 is installed inside the mounting base 3. A control button 6 is electrically connected to the control board 5 and extends out of the mounting base 3. The control board 5 is communicatively connected to the drive component 11, and the control button 6 controls the operation of the drive component 11 through the control board 5. By installing the control board 5 inside the mounting base 3, it is convenient to control the drive component 11 and the control button, and to control the start and stop of the drive component 11, thereby controlling the swaying of the support frame 300 and improving the reliability of the swaying mechanism 100.

[0085] In this embodiment, the control board 5 and the swing drive assembly 1 are arranged side by side along the front-to-back direction to improve the layout rationality. Specifically, the control board 5, the lower end of the connecting plate 22, and the drive component 11 are arranged sequentially at intervals along the lateral direction to avoid interference between the structures.

[0086] The lower side of the main seat 21 is an arc-shaped bottom edge 2121 with the opening facing downwards. The arc-shaped bottom edge 2121 is located above the control plate 5 to reduce the probability of interference between the rocker seat 2 and the control plate 5 when it rotates, while improving the overall structural compactness. Specifically, the lower side of the seat plate portion 212 has the aforementioned arc-shaped bottom edge 2121.

[0087] Furthermore, the upper side of the control board 5 preferably adopts an arc-shaped structure with a downward opening, so as to ensure the size requirements of the control board 5 while avoiding interference with the rocker seat 2.

[0088] It is worth noting, however, that the cooperation structure between the control panel 5 and the control button 6, and the structure of using the control button 6 to control the operation of the drive component 11, can adopt the structure in the prior art, and this utility model does not limit or elaborate on this.

[0089] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
