Description

A type of seat and a rocking chair

[0001] This application claims priority to Chinese Patent Application No. 202422996426.9, filed on December 5, 2024, and Chinese Patent Application No. 202520975262.3, filed on May 16, 2025, the disclosures of which are incorporated herein by reference in their entirety. Technical Field

[0002] This invention relates to the field of home furnishings, and more particularly to a seat, and also to a rocking chair having such a seat. Background Technology

[0003] With the fast pace of modern life, people are increasingly demanding greater comfort and health in their homes. Beds, chairs, and sofas, as indispensable pieces of furniture in daily life, are gradually becoming more multifunctional and intelligent in design. Traditional beds, chairs, and sofas mostly only offer basic sitting and lying functions, lacking elements of enjoyment and health promotion. In recent years, some beds, chairs, and sofas that can rock have appeared on the market. These products help users relax their minds and bodies and relieve physical fatigue and stress by simulating natural rocking movements.

[0004] However, in existing rocking furniture, when the drive mechanism stops working, the rocking seat may continue to rotate for a period of time due to inertia. This not only affects the user experience but may also threaten the stability of the product. Therefore, a mechanism capable of smooth braking is needed to ensure that the rocking seat can stop rotating quickly and smoothly when the drive mechanism stops working. Summary of the Invention

[0025] According to a preferred embodiment, the seat further includes a footrest assembly, the base includes a first end located outside the base near the footrest assembly and a second end located outside the base away from the footrest assembly, and a crossbar located at the first end and / or the second end is disposed between the rocking seats.

[0026] According to a preferred embodiment, the drive element, configured as a rubber friction block, is connected to the rocker seat via a crossbar.

[0033] According to a preferred embodiment, the rocking chair is designed as a sofa.

[0034] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0035] 1. The seat of the present invention can swing in both non-electric and electric swing modes. This design provides users with more diverse and flexible usage scenarios and improves user comfort.

[0036] 2. In this invention, the driving component and the power output shaft of the driving device cooperate with each other via a detachable connection. Therefore, unlike existing technologies, the driving device configuration does not prevent the user from manually driving the rocking seat to swing relative to the base.

[0037] 3. The detachable connection between the drive component and the power output shaft can be varied. For example, the power output shaft can be constructed as a driven rotating friction shaft, while the drive component can be constructed as a rubber friction block. In this method, the rubber friction block not only transmits frictional force to drive the rocker seat to oscillate, but also cleverly incorporates a braking mechanism. When the friction shaft stops rotating, the rocker seat may continue to rotate due to inertia. The cooperation between the braking mechanism and the friction shaft provides the necessary braking distance for this inertial rotation, allowing the rocker seat to stop smoothly at the desired position, enhancing safety and comfort during use.

[0038] 4. This invention, by cleverly placing the mounting base outside the base frame and combining it with a rotatable pivoting method using elastic components, helps optimize the internal spatial layout of the system, reducing the complexity of internal wiring and mutual interference. Simultaneously, this design may also improve the heat dissipation conditions of the power module, facilitating its inspection and maintenance.

[0039] 5. This invention uses the friction between the friction shaft in the power module and the rubber friction block fixed to the rocker seat to drive the rocker seat to reciprocate back and forth relative to the base. This design avoids the complex gear or chain structure in traditional mechanical drives, making the entire drive system simpler, more compact, and easier to maintain and repair.

[0040] 6. This invention uses elastic components (such as a pivot seat, pivot shaft, and torsion spring or compression spring) to rotatably pivot the power module to the base, ensuring tight contact between the friction shaft and the rubber friction block. This design not only simplifies the installation process but also improves drive efficiency, making the transmission of friction force more stable and reliable. Attached Figure Description

Some embodiments of the invention will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0066] Referring to Figures 1 to 5, one embodiment of the present invention discloses a rocking chair with a seat and its application, which can be designed as a sofa, including: a base 100, a rocking seat 200, and a drive device 300. In this embodiment, the rocking seat 200 is disposed above the base 100 and is capable of reciprocating back and forth relative to the base 100. The base 100 includes a base frame 101 and a rotating frame 102. The base frame 101 is designed to rock-support the rocking seat 200 and is rotatably mounted relative to the rotating frame 102. In other embodiments, the base frame 101 and the rotating frame 102 may also be mounted in a non-rotational manner. The drive device 300 is disposed between the base 100 and the rocking seat 200 and is capable of driving the rocking seat 200 to rock relative to the base 100.

[0067] In addition, the base 100 may also include a mounting base 110, which is fixedly connected to the base frame 101 and can extend forward or backward relative to the base frame 101 according to specific design requirements.

[0068] Please refer to Figure 6. In this embodiment, a drive device 300 is provided between the base 100 and the rocking seat 200 to actively drive the rocking seat to rock relative to the base in electric rocking mode.

[0069] The drive unit 300 includes a power module 301, an elastic member 302, and a drive element 303. The power module 301 has a housing 3011 and a power output shaft 3012 movable relative to the housing 3011. The housing 3011 is connected to the base 100 via the elastic member 302, and the drive element 303 is connected to the rocking seat 200. The power output shaft 3012 is detachably connected to the drive element 303, thereby allowing the rocking seat 200 to rock relative to the base 100 in both non-electric rocking and electric rocking modes.

[0070] In one embodiment, the power output shaft 3012 can be configured as a driven rotating friction shaft, and the drive member 303 can be configured as a rubber friction block, wherein the friction shaft and the rubber friction block maintain frictional contact. The power module 301 is rotatably pivotally connected to the base 100 via an elastic member 302, and the drive member 303, configured as a rubber friction block, is fixed to the rocking seat 200. When the power output shaft 3012, configured as a friction shaft, performs forward and reverse rotation, it can drive the rocking seat 200 to rock relative to the base 100 by frictional force, and the elastic member 302 applies force to the power module 301 in the direction in which the friction shaft contacts the rubber friction block.

[0071] In an embodiment not shown, the power output shaft 3012 may also be magnetically connected to the drive member 303, thereby forming a detachable connection between the two.

[0072] In this embodiment, the power module 301 is rotatably pivotally connected to the space defined by the base frame 101 of the base 100 via an elastic member 302. In this case, the mounting base 110 is fixedly connected to the base frame 101 and protrudes towards the rear of the user sitting on the seat. The elastic member 302 includes a pivot seat 3021, a pivot shaft 3022, and a torsion spring 3023; the pivot seat 3021 is fixed to the mounting base 110 of the base 100, the pivot shaft 3022 passes through the housing 3011 and is mounted on the pivot seat 3021; ​​the torsion spring 3023 is mounted on the pivot shaft 3022, wherein the two legs of the torsion spring 3023 respectively abut against the housing 3011 and the mounting base 110 of the base 100.

[0073] Referring to Figures 7 and 8, the contact surface between the driving member 303, which is constructed as a rubber friction block, and the power output shaft 3012, which is constructed as a friction shaft, is an arc-shaped surface 800, located on the lower surface of the rubber friction block. In this embodiment, the contact surface between the rubber friction block and the friction shaft is concave relative to the friction shaft, thus forming a concave arc-shaped surface 801. This design not only increases the contact area and improves the friction efficiency, but also makes the contact more uniform, reducing vibration and noise caused by uneven friction. At the same time, the concave arc-shaped surface can better adapt to the movement trajectory of the friction shaft, further improving the stability and reliability of the drive system. The rubber friction block includes a driven part 3031 and a braking part 3032. The driven part 3031 is configured to generate relative motion with the friction shaft by friction when the friction shaft is driven, and the braking part 3032 is configured to cooperate with the friction shaft to provide a braking distance for the rotation caused by inertia when the friction shaft ends the driven rotation. Specifically, the braking part 3032 is disposed at both ends of the driven part 3031.

[0074] It is important to note that the motor shaft (friction shaft 3012 in this embodiment) generally refers to the axis along which the angular momentum generated during motor rotation resides; it is an inertial axis. Motor rotational inertia, also known as the moment of inertia, is a physical quantity describing the inertial characteristics of a motor during rotation. It reflects the motor rotor's resistance to external changes (such as changes in speed or load) during rotation, and its tendency to maintain its original state of motion (such as uniform rotation). Because the motor itself possesses rotational inertia, a certain distance is needed to prevent the rubber friction block from rotating too far relative to the friction shaft.

[0075] The working process or principle of this invention is as follows:

[0076] This seat has two usage modes: non-electric rocking and electric rocking. In the non-electric manual rocking mode, the user applies force back and forth to make the rocking seat swing, and the rubber friction block makes the rocking smooth.

[0077] When the electric-driven rocking motion is in operation, the friction generated by the rotation of the friction shaft and the friction of the rubber friction block causes the rocking seat to swing automatically. The rubber friction block allows the friction shaft and the rocking seat to move asynchronously. When the rocking motion is stopped by an external force, the rubber friction block is lengthened to provide a braking distance and prevent the friction shaft and the rubber friction block from moving too far relative to each other, thus avoiding injury to the user. The safety of the rocking seat is relatively high.

[0078] In this embodiment, to ensure smooth and safe use, the friction shaft and the rubber friction block are brought into contact. The use of the rubber friction block has the following two advantages:

[0079] Firstly, it can increase the friction between the friction shaft and the friction block, allowing for faster initiation of the swing.

[0080] Secondly, it can provide a buffering effect when the friction shaft and friction block move asynchronously, ensuring safe use.

[0081] In addition, in some embodiments, in order to improve the service life of the friction shaft, a ball or roller that rotates integrally with the friction shaft can be installed on the friction shaft, or a rubber layer can be wrapped around the friction shaft.

[0082] Here, a torsion spring 3023 provides pre-tightening pressure between the friction shaft and the rubber friction block. Before startup or during oscillation, the elastic member 302 ensures a tight fit between the friction shaft and the rubber friction block, facilitating the stable generation of frictional force.

[0083] In other embodiments, other spring components, such as compression springs, can be used to replace the torsion springs; wherein the upper and lower ends of the compression springs respectively abut against the housing 3011 and the base 100. The effect is the same as that of the torsion springs, but during use, a limiting device is required to prevent the compression springs from deviating.

[0084] Referring to Figure 9, the present invention uses a pair of spaced-apart link assemblies 400 to allow the rocker seat to move up and down and back and forth at its hinge point with the base, thus achieving rocking motion. The link assembly 400 includes a first link 401, a second link 402, and a third link 403. The upper ends of the first link 401 and the second link 402 are respectively hinged to the base; wherein the first link 401 is hinged to the front end of the base, and the second link 402 is hinged to the rear end of the base 100. The lower ends of the first link 401 and the second link 402 are respectively connected to the lower end of the third link 403; the upper end of the third link 403 is connected to the rocker seat 200. The pair of link assemblies 400 spaced apart on both sides of the seat can be connected by crossbars 700 respectively arranged at the front and rear to ensure the synchronicity of the rocking motion; or the synchronicity of the rocking motion can be directly ensured by the rocker seat 200. Here, the third link 403 is preferably a "U"-shaped rod, which allows the center of gravity of the rocker seat 200 to be low, ensuring safe use. A reinforcing rod 404 is provided between the third link 403 and the rocker seat 200 to increase the load-bearing capacity of the rocker seat.

[0085] Referring to Figure 10, the present invention also includes a pair of foot rest assemblies 500 symmetrically arranged along the width direction of the seat body; the foot rest assembly 500 is used to extend the length of the rocking seat 200. The foot rest assembly 500 includes a driving rod 501, a first driven rod 502, a second driven rod 503, a third driven rod 504, and a fourth driven rod 505. The upper ends of the driving rod 501 and the second driven rod 503 are respectively hinged to the rocking seat 200; the lower end of the driving rod 501 is hinged to the lower end of the first driven rod 502. The lower end of the second driven rod 503 is hinged to the lower end of the third driven rod 504. The middle portion of the third driven rod 504 is hinged to the driving rod 501. The upper ends of the third driven rod 504 and the first driven rod 502 are respectively hinged to the fourth driven rod 505. The spaced-apart foot rest assemblies 500 are connected by a linkage 506. The linkage 506 is moved by a push rod 507 hinged to the linkage 506.

[0086] The working process of the footrest assembly 500 is as follows: The push rod 507, which is an electric push-pull rod (such as a motor screw assembly or a motor gear rack assembly), is installed on the rocker base 200. The push rod 507 extends and pushes the connecting rod 506 forward. The connecting rod 506 causes the spaced footrest assemblies to move together. At this time, the driving rod 501 swings forward, and then the second driven rod 503, the third driven rod 504, and the fourth driven rod 505 swing and extend accordingly, realizing the extension of the front end of the rocker base 200, which allows the dangling lower leg to extend until it is level with the thigh.

[0087] Referring to Figure 11, the present invention also includes a pair of backrest angle adjustment components 600 spaced apart along the width direction of the seat. Each backrest angle adjustment component 600 includes a long connecting rod 601, a short connecting plate 602, and a connecting rod located between the long connecting rod 601 and the short connecting plate 602 for connecting the two. Here, the backrest angle adjustment component 600 is linked with the footrest assembly, activating simultaneously when the footrest assembly is activated, allowing the seat to recline or semi-recline. Specifically, one end of the long connecting rod 601 is hinged to the middle of the second driven rod 503; the other end of the long connecting rod is hinged to one end of the short connecting plate; and the other end of the short connecting plate 602 is hinged to the rocking seat 200. Its working process is as follows: when the second driven rod 503 extends, it pulls the long connecting rod 601 forward, then drives the short connecting plate forward, and then the rocking seat swings backward at the point of hinge with the short connecting plate; the reclining or semi-reclining position is achieved according to the extension length of the second driven rod 503. It should be noted that in this embodiment, a pair of rubber friction blocks 303 arranged at intervals along the width direction of the seat are mounted on the rocking seat 200 via a crossbar 700.

[0088] This seat, originally intended for use in beds, chairs, or sofas, features a rocking function, allowing users to transition from sitting to lying down during the rocking motion. It is safe, reliable, and comfortable to use.

[0089] Figures 12 to 19 illustrate another embodiment of the invention. In this embodiment, the mounting base 110 of the base 100 is fixedly connected to the base frame 101 and protrudes towards the front of the user sitting on the seat, i.e., towards the footrest assembly 500. The power module 301 is rotatably pivotally connected to the mounting base 110 via an elastic member 302. In the prior art, the base frame 101 is typically used to support and fix various devices or modules, including power modules. These power modules are often fixed inside the base frame by direct mounting or rigid connection. However, this design has some problems. First, directly mounting the power module inside the base frame may limit its installation position and layout flexibility, which is not conducive to equipment maintenance and upgrades. Second, the installation method of directly mounting the power module inside the base frame may cause damage or performance degradation of the power module when subjected to internal impact or vibration, affecting the stability and reliability of the overall equipment. Therefore, this application provides mounting bases at the front / rear positions outside the frame formed by the base, and the mounting bases should not be limited by the internal space of the base frame, thereby improving the overall layout flexibility of the equipment.

[0090] Please refer to Figure 14. The elastic member 302 includes a pivot seat 3021, a pivot shaft 3022, and a torsion spring 3023. The pivot seat 3021 is fixed on the mounting seat 110 of the base 100. The pivot shaft 3022 passes through the housing 3011 and is mounted on the pivot seat 3021. The torsion spring 3023 is mounted on the pivot shaft 3022. The two legs of the torsion spring 3023 respectively abut against the housing 3011 and the mounting seat 110.

[0091] The base includes a first end located outside the base near the foot rest assembly and a second end located outside the base away from the foot rest assembly. A crossbar 700 located at the first and second ends is disposed between the rocking base 200, and the rubber friction block is mounted on the rocking base via the crossbar 700 located at the second end. Alternatively, in other embodiments, the rubber friction block may be mounted on the rocking base via the crossbar 700 located at either the first or both ends.
