DETAILED DESCRIPTION

[0049] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0050] The following describes the spring-type rhythmic movement and rhythmic furniture of the present application in conjunction with Figures 1 to 9. The rhythmic furniture includes the spring-type rhythmic movement. It should be noted that the rhythmic furniture can be a rhythmic chair, a rhythmic bed, etc. In the embodiments of the present application, the rhythmic furniture is described as a rhythmic chair.

[0051] 1 to 7 , a spring-type rhythm movement is provided according to the present application, including a first frame 10 , a second frame 20 , a driving mechanism 30 and a spring-type orientation structure 40 .

[0052] Specifically, the second frame 20 and the first frame 10 can move forward and backward relative to each other, and the power output end of the driving mechanism 30 is transmission-connected to the second frame 20, and the driving mechanism 30 drives the second frame 20 to move back and forth relative to the first frame 10; the spring clip orientation structure 40 is vertically arranged, and one end of the spring clip orientation structure 40 is connected to the first frame 10, and the other end of the spring clip orientation structure 40 is connected to the second frame 20. The spring clip orientation structure 40 moves with the second frame 20 and can be elastically deformed, and the deformation direction of the spring clip orientation structure 40 is consistent with the movement direction of the second frame 20.

[0053] The shrapnel-type rhythm movement provided by the present application has the following features: when the driving mechanism 30 drives the second frame 20 to move relative to the first frame 10, the shrapnel-oriented structure 40 can elastically deform along the moving direction of the second frame 20, while the moving direction of the second frame 20 is limited by the structure of the shrapnel-oriented structure 40 itself, which is beneficial to avoid the second frame 20 deviating from the moving direction, that is, preventing the second frame 20 from shaking due to deviating from the moving direction, thereby improving the stability of the shrapnel-type rhythm movement during rhythm and improving the user's comfort. At the same time, it has a simple structure, low cost and long service life.

[0054] It should be noted that the supporting body for supporting the user is installed on the second frame 20. The supporting body can be a sofa or a bed, which is fixed to the second frame 20 by screws.

[0055] There are two ways of matching the first frame 10, the second frame 20 and the spring orientation structure 40. The first is that the upper end of the spring orientation structure 40 is connected to the first frame 10, and the lower end of the spring orientation structure 40 is connected to the second frame 20; in this way, the second frame 20 is equivalent to being suspended on the first frame 10 by the spring orientation structure 40; it is beneficial to avoid the situation where the second frame deviates from the moving direction, that is, to prevent the second frame from deviating from the moving direction and shaking, thereby improving the stability of the spring-type rhythm movement during rhythm and improving the user's comfort. At the same time, it has a simple structure, low cost and long life; the second is that the lower end of the spring orientation structure 40 is connected to the first frame 10, and the upper end of the spring orientation structure 40 is connected to the second frame 20, and the second frame 20 is equivalent to being lifted by the spring orientation structure 40 above the first frame 10. It plays a lifting role on the second frame, improves the load-bearing and supporting effects, can play a buffering role during the movement of the second frame, achieves a regular rhythmic massage effect, can help lift the second frame and maintain its stability, protect related components from damage, and improve the user's comfort.

[0056] It can be understood that, referring to Figures 1, 2, 6, and 7, in this embodiment, the spring-type 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; wherein, when the second frame 20 and the first frame 10 move relative to each other, the direction of the force applied by the second frame 20 to the elastic plate 41 is perpendicular to the plate surface of the elastic plate 41. With the above structure, when the second frame 20 moves, the elastic plate 41's own bending elasticity disperses and absorbs the force to define the movement direction of the second frame 20; compared with the steel wire rope of the prior art, the elastic plate 41, due to its planar shape and better structural stability, can prevent the second frame 20 from deviating from the movement direction, thereby improving the stability of the spring-type rhythm movement during rhythm and enhancing the comfort of the user.

[0057] It should be noted that, in this embodiment, since the second frame 20 and the first frame 10 move relative to each other in the spatial direction and the second frame 20 is arranged to cover the first frame 10, the elastic plate 41 is arranged vertically.

[0058] Specifically, referring to Figures 1, 2, 6, and 7, some embodiments of the present application further include a spacing structure 50, which is used to space the upper end of the elastic plate 41 from the first frame 10, and the lower end of the elastic plate 41 from the second frame 20. With this structure, when the second frame 20 moves relative to the first frame 10, the provision of the spacing structure 50 helps prevent the elastic plate 41 from contacting or colliding with the first frame 10 and the second frame 20 during the elastic deformation process, thereby reducing noise and improving comfort during use.

[0059] Specifically, with reference to Figures 1, 2, 6 and 7, in some embodiments of the present application, the spacing structure 50 includes: a first spacing plate 51, the first spacing plate 51 is provided between the upper end of the elastic plate 41 and the first frame 10, the upper end of the first spacing plate 51 is connected to the first frame 10, the other end of the first spacing plate 51 is connected to the upper end of the elastic plate 41, the first spacing plate 51 is provided with a first recess 511 adapted to the width of the elastic plate 41; a second spacing plate 52, the second spacing plate 52 is provided between the lower end of the elastic plate 41 and the second Between the frames 20, one end of the second spacer 52 is connected to the second frame 20, and the other end of the second spacer 52 is connected to the lower end of the elastic plate 41, and the second spacer 52 is provided with a second recess 521 adapted to the width of the elastic plate 41; wherein, the thickness of the first spacer 51 is equal to or less than the distance between a plate surface of the elastic plate 41 facing the first frame 10 and the first frame 10, and the thickness of the second spacer 52 is equal to or less than the distance between a plate surface of the elastic plate 41 facing the second frame 20 and the second frame 20.

[0060] Through the above structure, the upper end of the elastic plate 41 is connected to the first frame 10 through the first spacer 51, and the lower end is connected to the second frame 20 through the second spacer 52, further avoiding direct contact between the elastic plate 41 and the first frame 10 and the second frame 20; at the same time, the first spacer 51 is provided with a first recess 511, and the second spacer 52 is provided with a second recess 521. During the elastic deformation of the elastic plate 41, the first recess 511 and the second recess 521 can provide deformation space for the elastic plate 41, play an avoidance role, and have a deformation guiding and protective effect on the elastic plate 41. The above structure is conducive to reducing noise, improving comfort during use, and thus making the structure more reasonable.

[0061] It should be noted that the thickness of the first partition plate 51 and the second partition plate 52 can be selected to ensure that the elastic plate 41 avoids contact and collision with the first frame 10 and the second frame 20 when deforming.

[0062] Specifically, referring to Figures 2, 6 and 7, in an embodiment of the present application, the upper end of the elastic plate 41 is detachably connected to the first spacer plate 51, and the lower end of the elastic plate 41 is detachably connected to the second spacer plate 52, which is convenient for disassembly and maintenance.

[0063] It should be noted that the above-mentioned first partition plate 51 and the second partition plate 52 are both n-shaped. Of course, the first partition plate 51 and the second partition plate 52 can also be V-shaped, etc.; the above-mentioned first frame 10 is welded with a first welding plate, and one side wall of the first partition plate 51 is welded to the first welding plate. Of course, one side wall of the first partition plate 51 can also be detachably connected to the first welding plate by means of buckling, bolting, etc.; the above-mentioned second frame 20 is welded with a second welding plate, and one side wall of the second partition plate 52 is welded to the second welding plate. Of course, one side wall of the second partition plate 52 can also be detachably connected to the second welding plate by means of buckling, bolting, etc., which is not limited here.

[0064] Specifically, referring to Figures 2, 6, and 7, in this embodiment, the upper and lower ends of the elastic plate 41 are each provided with a connecting through-hole 411, the first spacer plate 51 is provided with a first mounting through-hole 512, and the second spacer plate 52 is provided with a second mounting through-hole 522. The connecting through-hole 411 at the upper end of the elastic plate 41 corresponds to the first mounting through-hole 512, and the connecting through-hole 411 at the lower end of the elastic plate 41 corresponds to the second mounting through-hole 522. It can be understood that the connecting through-hole 411 and the first mounting through-hole 512 are penetrated by a first bolt and screwed to a first nut, and the connecting through-hole 411 and the second mounting through-hole 522 are penetrated by a second bolt and screwed to a second nut, so that the elastic plate 41 is configured to be detachable, with a simple structure and easy manufacturing and maintenance. Of course, in some embodiments, the connection can also be detachably connected by other means, such as a snap-fit ​​structure, or fixedly connected by welding, which is not limited here.

[0065] Specifically, referring to Figures 2, 6, and 7, in some embodiments of the present application, the spring-element orientation structure 40 further includes a plurality of washers 42, each of which is engaged with each of the connection holes 411 on the elastic plate 41. It can be understood that a bolt passes through the washers 42 located in the connection holes 411 and is screwed to the nut, resulting in a simple structure that reduces friction on the elastic plate 41 and improves connection stability.

[0066] It should be noted that each set of the spring-piece orientation structures 40 has four washers 42 in total, which are set according to the number of the connecting through holes 411 .

[0067] Specifically, referring to Figures 2, 6, and 7, in some embodiments of the present application, the spring-piece orientation structure 40 further includes two pressure plates 43, which are located at the upper and lower ends of the elastic plate 41, respectively. The pressure plates 43 cover one side of the gasket 42, and the pressure plates 43 are provided with mating through holes 431 that communicate with the hollow portion of the gasket 42. By providing the pressure plates 43 to cover the gasket 42, the stability of the elastic plate 41 can be improved during installation and when the elastic plate 41 is deformed.

[0068] It should be noted that the elastic plate 41 is made of a rigid material. Of course, in some embodiments, the spring orientation structure 40 can also be configured as a tension spring, a torsion spring, or an elastic column, etc., depending on the specific structure, and is not limited here.

[0069] It can be understood that, with reference to Figures 1, 2 and 3, in some embodiments of the present application, the spring clip orientation structure 40 is a plurality of groups, some groups of spring clip orientation structures 40 are located on the front side of the cooperation between the first frame 10 and the second frame 20, and the remaining groups of spring clip orientation structures 40 are located on the rear side of the cooperation between 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.

[0070] Specifically, referring to Figure 1, in this embodiment, the above-mentioned spring-piece orientation structures 40 are four groups, and the corresponding spacing structures 50 are set to four groups, which is the same as the number of the spring-piece orientation structures 40. It can be understood that two groups of spring-piece orientation structures 40 are respectively provided on the relative front and rear sides of the first frame 10 and the second frame 20, further improving the stability of movement.

[0071] Of course, the above-mentioned spring clip orientation structures 40 are not limited to four groups. In some embodiments, the above-mentioned spring clip orientation structures 40 can also be one group, two groups, three groups or more. For example, one group of spring clip orientation structures 40 is provided on the relative front and rear sides of the first frame 10 and the second frame 20; one group of spring clip orientation structures 40 is provided on the relative front sides of the first frame 10 and the second frame 20, and two groups of spring clip orientation structures 40 are provided on the rear sides; or three groups of spring clip orientation structures 40 are provided on the relative front and rear sides of the first frame 10 and the second frame 20, or, in some cases, when the spring clip orientation structures 40 are one group, one group of spring clip orientation structures 40 is provided on the relative front or rear sides of the first frame 10 and the second frame 20, which is not limited here.

[0072] It can be understood that, with reference to Figures 1 to 3 and Figures 8 and 9, in some embodiments of the present application, the drive mechanism 30 includes: a drive motor 31, which is disposed on the first frame 10; a transmission assembly 32, one end of which is in transmission connection with the output shaft of the drive motor 31; and a reciprocating unit 33, one end of which is eccentrically connected to the other end of the transmission assembly 32, and the other end of which is connected to the second frame 20. With the above structure, when the drive motor 31 is in operation, the eccentric transmission between the transmission assembly 32 and the reciprocating unit 33 causes the second frame 20 to reciprocate back and forth relative to the first frame 10. The eccentric arrangement is conducive to adjusting pressure, controlling vibration, and achieving mechanical transmission.

[0073] Specifically, referring to Figures 1 to 3 and Figures 8 and 9, in some embodiments of the present application, the transmission assembly 32 includes: an eccentric shaft 321, rotatably provided on the first frame 10, the reciprocating unit 33 is transmission-connected to the eccentric shaft 321; a driving pulley 322, transmission-connected to the drive motor 31; a driven pulley 323, sleeved on the eccentric shaft 321; a transmission belt 324, wound around the driving pulley 322 and the driven pulley 323; wherein, the rotation center line of the partial structure at the cooperation point between the reciprocating unit 33 and the eccentric shaft 321 and the rotation center line of the partial structure at the cooperation point between the driven pulley 323 and the eccentric shaft 321 do not coincide, and an inertia wheel 325 is provided on the end of the eccentric shaft 321 away from the driven pulley 323. With the above structure, the pulley drive has a certain elasticity, which can reduce the impact and vibration in the mechanical transmission, and can provide a simple, flexible and economical power transmission method, so that the spring-type rhythm movement has better stability when moving back and forth; secondly, the inertia wheel 325 can smooth the output torque of the drive motor 31, adjust the speed response, provide additional energy output, and enhance the stability of the transmission.

[0074] Of course, in some embodiments, the transmission assembly 32 may also be a sprocket transmission, etc., which is not limited here.

[0075] Specifically, referring to Figures 3, 8 and 9, in an embodiment of the present application, the reciprocating moving unit 33 includes: a first reciprocating plate 331, the first reciprocating plate 331 is connected to the eccentric shaft 321; a second reciprocating plate 332, the second reciprocating plate 332 is connected to the second frame 20; a deformation plate 333, one end of the deformation plate 333 is connected to the first reciprocating plate 331, and the other end of the deformation plate 333 is connected to the second reciprocating plate 332, and there is a gap between the facing ends of the first reciprocating plate 331 and the second reciprocating plate 332. With the above structure, when the eccentric shaft 321 is eccentrically transmitted, the first reciprocating plate 331 swings up and down while moving back and forth. Therefore, in the process of the first reciprocating plate 331 being transmitted to the second reciprocating plate 332, the deformation plate 333 is provided between the first reciprocating plate 331 and the second reciprocating plate 332. The deformation plate 333 adapts to the up and down swing of the first reciprocating plate 331 through its deformation, so as to avoid the up and down swing when the power is transmitted to the second reciprocating plate 332, so that the second reciprocating plate 332 can more stably drive the second frame 20 to move relative to the first frame 10, and the transmission is smooth, which is conducive to reducing noise, and the structure is simple and the manufacturing cost is low.

[0076] Specifically, referring to Figures 3, 8 and 9, in an embodiment of the present application, the reciprocating moving unit 33 also includes a first pad 334 and a second pad 335, and there is a gap between the first pad 334 and the second pad 335. The first pad 334 corresponds to the first reciprocating plate 331, and the second pad 335 corresponds to the second reciprocating plate 332. One end of the deformation plate 333 is clamped between the first reciprocating plate 331 and the first pad 334, and the other end is clamped between the second reciprocating plate 332 and the second pad 335, which can further improve the assembly stability and transmission performance of the deformation plate 333.

[0077] It should be noted that the gap between the first pad 334 and the second pad 335 is equal to the gap between the opposite ends of the first reciprocating plate and the second reciprocating plate 332, which is conducive to ensuring that the deformation amplitude of the deformable plate 333 is consistent when moving forward and backward, thereby maintaining stability; the above-mentioned deformable plate 333 is a rubber plate, and the first reciprocating plate 331 and the second reciprocating plate 332 are detachably connected to the rubber plate by bolting or the like; of course, the deformable plate 333 can also be a thinner steel plate, which can help ensure that the second reciprocating plate 332 only moves forward and backward without swinging up and down during movement, and this is not limited here; the above-mentioned first reciprocating plate 331 and the second reciprocating plate 332 can be formed by detachably connecting multiple spliced ​​plates; in some embodiments, the first reciprocating plate 331 and the second reciprocating plate 332 can also be a plate body or a column, which is not limited here.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
