Modes for Carrying Out the Invention

[0021] To more clearly explain the purpose, technical solutions, and advantages of this application, the following provides a clear and complete description of the technical solutions in the embodiments of this application, in conjunction with the drawings of this application, and it is clear that the embodiments described are only a part of this application, not the entirety. All other embodiments that a person skilled in the art could obtain without creative effort based on the embodiments of this application are within the scope of protection of this application.

[0022] Referring to Figures 1 to 9, the elastic piece type rhythmic mechanism and rhythmic furniture of this application will be described below, with the rhythmic furniture including the elastic piece type rhythmic mechanism. Regarding the type of rhythmic furniture, it may be a rhythmic chair, a rhythmic bed, etc., and in the embodiments of this application, a rhythmic chair will be described as an example of rhythmic furniture.

[0023] Referring to Figures 1 to 7, the elastic piece type rhythmic mechanism provided by this application includes a first frame 10, a second frame 20, a drive mechanism 30, and an elastic piece directional structure 40.

[0024] Specifically, the second frame 20 and the first frame 10 are relatively movable in the forward and backward directions, the power output end of the drive mechanism 30 is drivably connected to the second frame 20, the drive mechanism 30 drives the second frame 20 to reciprocate relative to the first frame 10, the elastic piece directional structure 40 is positioned vertically, one end of the elastic piece directional structure 40 is connected to the first frame 10, and the other end of the elastic piece directional structure 40 is connected to the second frame 20, the elastic piece directional structure 40 moves in accordance with the movement of the second frame 20 and is elastically deformable, with the deformation direction being the same as the movement direction of the second frame 20.

[0025] In the elastic piece type rhythmic mechanism provided by this application, when the drive mechanism 30 drives the second frame 20 to move relative to the first frame 10, the elastic piece directional structure 40 can elastically deform in accordance with the direction of movement of the second frame 20, and the direction of movement of the second frame 20 is restricted by the elastic piece directional structure 40 itself. This is advantageous in avoiding situations in which the second frame 20 deviates from the direction of movement, that is, in preventing the phenomenon of the second frame 20 deviating from the direction of movement and swaying, improving the stability of the elastic piece type rhythmic mechanism during movement, improving user comfort, and also having a simple structure, low cost, and long service life.

[0026] Note that the main body supporting the user is attached to the second frame 20 and may be a sofa or a bed, in which case it is fixed to the second frame 20 via screws.

[0027] The first frame 10, the second frame 20, and the elastic piece directional structure 40 are combined with each other in two ways. In the first method, the upper end of the elastic piece directional structure 40 is connected to the first frame 10, and the lower end of the elastic piece directional structure 40 is connected to the second frame 20. In this method, the second frame 20 is equivalent to being suspended from the first frame 10 by the elastic piece directional structure 40, which is advantageous in avoiding situations where the second frame deviates from the direction of movement, i.e., in preventing the phenomenon of the second frame deviating from the direction of movement and swaying, improving the stability of the elastic piece type rhythmic mechanism during movement, improving user comfort, and also having a simple structure, low cost, and long service life. In the second method, the lower end of the elastic piece directional structure 40 is connected to the first frame 10, and the upper end of the elastic piece directional structure 40 is connected to the second frame 20. In this method, the second frame 20 is equivalent to being lifted above the first frame 10 by the elastic piece directional structure 40. It plays a role in lifting the second frame, improving the bearing and support effect, acting as a buffer during the movement of the second frame, achieving a regular, rhythmic massage effect, helping to lift the second frame and maintain its stability, protecting related components from damage, and improving user comfort.

[0028] To make it clear, referring to Figures 1, 2, 6, and 7, in this embodiment, the elastic piece directional structure 40 includes an elastic plate 41, the upper end of which is connected to the first frame 10, and the lower end of which is connected to the second frame 20, where, when the second frame 20 and the first frame 10 move relative to each other, the direction of the force exerted by the second frame 20 on the elastic plate 41 is perpendicular to the plate surface of the elastic plate 41. By adopting the above structure, when the second frame 20 moves, the force is dispersed and absorbed by the bending elasticity of the elastic plate 41 itself, the direction of movement of the second frame 20 is restricted, and compared to conventional wire ropes, the elastic plate 41 has a planar shape and excellent structural stability, so that the second frame 20 does not deviate from the direction of movement, improving the stability of the elastic piece type rhythmic mechanism during movement and improving user comfort.

[0029] In this embodiment, the second frame 20 and the first frame 10 move relative to each other in the spatial direction, and the second frame 20 is positioned over the first frame 10, so the elastic plate 41 is positioned vertically.

[0030] Specifically, referring to Figures 1, 2, 6, and 7, some embodiments of this application further include a partition structure 50 for positioning the upper end of the elastic plate 41 and the first frame 10, and the lower end of the elastic plate 41 and the second frame 20 at a distance from each other. With this structure, when the second frame 20 moves relative to the first frame 10, the installation of the partition structure 50 is advantageous in preventing the elastic plate 41 from contacting or colliding with the first frame 10 and the second frame 20 during elastic deformation of the elastic plate 41, thereby reducing noise and improving comfort during use.

[0031] Specifically, referring to Figures 1, 2, 6, and 7, in some embodiments of this application, the partition structure 50 includes a first spacer 51 provided between the upper end of the elastic plate 41 and the first frame 10, with its upper end connected to the first frame 10 and its other end connected to the upper end of the elastic plate 41, and having a first recess 511 that conforms to the width of the elastic plate 41; and a second spacer 52 provided between the lower end of the elastic plate 41 and the second frame 20, with one end connected to the second frame 20 and its other end connected to the lower end of the elastic plate 41, and having a second recess 521 that conforms to the width of the elastic plate 41, wherein the first spacer 51 has a thickness less than or equal to the distance between the plate surface of the elastic plate 41 facing the first frame 10 and the first frame 10, and the second spacer 52 has a thickness less than or equal to the distance between the plate surface of the elastic plate 41 facing the second frame 20 and the second frame 20.

[0032] According to the above structure, the upper end of the elastic plate 41 is connected to the first frame 10 via the first spacer 51, and the lower end is connected to the second frame 20 via the second spacer 52. This further avoids direct contact between the elastic plate 41 and the first frame 10 and the second frame 20. Furthermore, the first spacer 51 is provided with a first recess 511, and the second spacer 52 is provided with a second recess 521. When the elastic plate 41 undergoes elastic deformation, the first recess 511 and the second recess 521 serve to recede, and also provide a deformation space for the elastic plate 41 that provides deformation guidance and protection. This structure is advantageous in reducing noise and improving comfort during use, making it more rational.

[0033] The thickness of both the first spacer 51 and the second spacer 52 should be such that the elastic plate 41 does not come into contact with or collide with the first frame 10 and the second frame 20 during deformation.

[0034] Specifically, referring to Figures 2, 6, and 7, in the embodiment of this application, the upper end of the elastic plate 41 is detachably connected to the first spacer 51, and the lower end of the elastic plate 41 is detachably connected to the second spacer 52, making attachment, detachment, and maintenance easy.

[0035] Although the first spacer 51 and the second spacer 52 are both N-shaped, they may of course be V-shaped or other shapes. The first welded plate is welded to the first frame 10, and one side wall of the first spacer 51 is welded to the first welded plate, but of course, they may be detachably connected to the first welded plate by snap-fit ​​or bolt-fit. The second welded plate is welded to the second frame 20, and one side wall of the second spacer 52 is welded to the second welded plate, but of course, they may be detachably connected to the second welded plate by snap-fit ​​or bolt-fit, and are not limited to these shapes.

[0036] Specifically, referring to Figures 2, 6, and 7, in this embodiment, connecting through holes 411 are provided at both the upper and lower ends of the elastic plate 41, a first mounting through hole 512 is provided in the first spacer 51, and a second mounting through hole 522 is provided in the second spacer 52. The connecting through hole 411 at the upper end of the elastic plate 41 is combined with the first mounting through hole 512, and the connecting through hole 411 at the lower end of the elastic plate 41 is combined with the second mounting through hole 522. As can be understood, the elastic plate 41 is detachably positioned, the structure is simple, and it is easy to manufacture and maintain, by screwing the first bolt through the connecting through hole 411 and the first mounting through hole 512 into the first nut, and the second bolt through the connecting through hole 411 and the second mounting through hole 522 into the second nut. Of course, in some embodiments, the components may be detachably connected by a fastening structure or the like, or fixedly connected by welding, and are not limited thereto.

[0037] Specifically, referring to Figures 2, 6, and 7, in some embodiments of this application, the elastic plate oriented structure 40 further includes a plurality of washers 42, each washer 42 being fitted one-to-one with each connecting through-hole 411 on the elastic plate 41. As can be understood, the bolt is screwed into the nut by passing through the washer 42 in the connecting through-hole 411, resulting in a simple structure, reduced friction on the elastic plate 41, and improved connection stability.

[0038] In addition, there are a total of four washers 42 in the elastic piece directional structure 40 of each group described above, and their number is set according to the number of connecting through holes 411.

[0039] Specifically, referring to Figures 2, 6, and 7, in some embodiments of this application, the elastic piece directional structure 40 further includes two pressing plates 43, each located at the upper and lower ends of the elastic plate 41, the pressing plates 43 are placed over one side of the washer 42, and the pressing plates 43 are provided with connecting through holes 431 that communicate with the hollow portion of the washer 42. The provision of pressing plates 43 that are placed over the washer 42 improves the stability of the elastic plate 41 during installation and when the elastic plate 41 is deformed.

[0040] The elastic plate 41 is made of steel. Of course, in some embodiments, the elastic piece directional structure 40 may be a tension spring, a torsion spring, an elastic column, etc., depending on the specific structure, and is not limited thereto.

[0041] To be understood, referring to Figures 1, 2, and 3, in some embodiments of this application, the elastic piece directional structure 40 is divided into several groups, some of which are located on the front side of the combination of the first frame 10 and the second frame 20, while the remaining groups of elastic piece directional structure 40 are located on the rear side of the combination of the first frame 10 and the second frame 20, thereby improving the stability of the relative movement between the second frame 20 and the first frame 10.

[0042] Specifically, referring to Figure 1, in this embodiment, there are four groups of elastic piece directional structures 40, and the corresponding partition structures 50 are set to four groups, the same as the number of elastic piece directional structures 40. This means that two groups of elastic piece directional structures 40 are provided on each of the opposing front and rear sides of the first frame 10 and the second frame 20, which further improves the stability of movement.

[0043] Of course, the elastic piece directional structure 40 is not limited to four groups, and in some embodiments, the elastic piece directional structure 40 may consist of one, two, three, or more groups. For example, one group of elastic piece directional structures 40 may be provided on each of the opposing front and rear sides of the first frame 10 and the second frame 20; one group of elastic piece directional structures 40 may be provided on the opposing front side of the first frame 10 and the second frame 20, and two groups of elastic piece directional structures 40 may be provided on the rear side; or three groups of elastic piece directional structures 40 may be provided on each of the opposing front and rear sides of the first frame 10 and the second frame 20; or, in some cases, if there is one group of elastic piece directional structures 40, one group of elastic piece directional structures 40 may be provided on either the opposing front or rear side of the first frame 10 and the second frame 20, and this is not limited to these examples.

[0044] To make it clear, referring to Figures 1-3 and 8-9, in some embodiments of this application, the drive mechanism 30 includes a drive motor 31 provided on the first frame 10, a transmission assembly 32 with one end drivably connected to the output shaft of the drive motor 31, and a reciprocating unit 33 with one end eccentrically drivably connected to the other end of the transmission assembly 32 and the other end connected to the second frame 20. By employing the above structure, when the drive motor 31 is operated, the second frame 20 reciprocates back and forth relative to the first frame 10 due to eccentric transmission between the transmission assembly 32 and the reciprocating unit 33, and the eccentric arrangement helps to achieve pressure regulation, vibration control, and mechanical transmission.

[0045] Specifically, referring to Figures 1 to 3, 8 and 9, in some embodiments of the present application, the transmission assembly 32 includes an eccentric shaft 321 rotatably positioned on a first frame 10 and trajectoryably connected to a reciprocating unit 33, a driving pulley 322 trajectoryably connected to a drive motor 31, a driven pulley 323 fitted onto the eccentric shaft 321, and a transmission belt 324 wrapped around the driving pulley 322 and the driven pulley 323, wherein the rotational centerline of the structure of the part of the reciprocating unit 33 cooperating with the eccentric shaft 321 does not coincide with the rotational centerline of the structure of the part of the driven pulley 323 cooperating with the eccentric shaft 321, and a flywheel 325 is provided at one end of the eccentric shaft 321 away from the driven pulley 323. By adopting the above structure, the pulley transmission has a predetermined inertia, which reduces shocks and vibrations in mechanical transmission, providing a simple, flexible, and economical power transmission method. This improves the stability of the elastic piece type rhythmic mechanism during reciprocating movement. Furthermore, the provision of the flywheel 325 smooths the output torque of the drive motor 31, modulates the speed response, provides additional energy output, and enhances the stability of the transmission.

[0046] Of course, in some embodiments, the transmission assembly 32 may be a sprocket transmission or the like, and is not limited thereto.

[0047] Specifically, referring to Figures 3, 8, and 9, in the embodiment of this application, the reciprocating unit 33 includes a first reciprocating plate 331 connected to an eccentric shaft 321, a second reciprocating plate 332 connected to a second frame 20, and a deformable plate 333 having one end connected to the first reciprocating plate 331 and the other end connected to the second reciprocating plate 332, with a gap between the opposing ends of the first reciprocating plate 331 and the second reciprocating plate 332. By adopting the above structure, when the eccentric shaft 321 is eccentrically transmitted, the first reciprocating plate 331 moves back and forth and simultaneously oscillates up and down. In the process of the first reciprocating plate 331 transmitting power to the second reciprocating plate 332, the deformable plate 333 provided between the first reciprocating plate 331 and the second reciprocating plate 332 adapts to the up and down oscillation of the first reciprocating plate 331 through its deformation, which is advantageous in avoiding up and down oscillation caused by power transmission to the second reciprocating plate 332. As a result, the second reciprocating plate 332 can drive the movement of the second frame 20 relative to the first frame 10 more smoothly, and because the transmission is smooth, it is advantageous in reducing noise. Furthermore, the structure is simple and the manufacturing cost is low.

[0048] Specifically, referring to Figures 3, 8, and 9, in the embodiment of this application, the reciprocating unit 33 further includes a first pad 334 and a second pad 335, with a gap between the first pad 334 and the second pad 335, the first pad 334 corresponding to a first reciprocating plate 331, the second pad 335 corresponding to a second reciprocating plate 332, one end of the deformation plate 333 being sandwiched between the first reciprocating plate 331 and the first pad 334, and the other end being sandwiched between the second reciprocating plate 332 and the second pad 335, thereby further improving the lifting stability and transmission performance of the deformation plate 333.

[0049] Furthermore, the gap between the first pad 334 and the second pad 335 is the same as the gap between the opposing ends of the first reciprocating plate 331 and the second reciprocating plate 332, which helps to match the deformation width of the deformation plate 333 when it moves back and forth and maintain stability. The deformation plate 333 is a rubber plate, and both the first reciprocating plate 331 and the second reciprocating plate 332 are detachably connected to the rubber plate by bolt fitting or the like. Of course, the deformation plate 333 may also be a thin steel plate, which helps to ensure that the second reciprocating plate 332 moves only back and forth without vibrating up and down during movement, and is not limited here. The first reciprocating plate 331 and the second reciprocating plate 332 may be formed by detachably connecting multiple connecting plate bodies, and in some embodiments, the first reciprocating plate 331 and the second reciprocating plate 332 may further be plate-shaped or columnar-shaped, and is not limited here.

[0050] Finally, it should be noted that the embodiments described above are merely for illustrating, and not limiting, the technical solutions of the present application. Although the present application has been described in detail with reference to the embodiments, it is possible to modify the technical solutions described in each of the embodiments or to replace some of their technical features with equivalents, as will be understood by those skilled in the art. Such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of the present application.
