Technical Field

[0001] This application relates to the technical field of seating, and particularly to a vertical rhythm device. Background Art

[0002] A seat is usually a seating furniture with a backrest for people to sit on. With the passage of time, the concept of a chair has gradually expanded and now refers to a seating furniture with a backrest and / or armrests. Seats can be classified according to different usage scenarios and materials, such as child safety seats, airport seats, car seats, bus seats, home seats, restaurant seats, etc.

[0003] As people's demand for seats increases, some seats use mechanical rolling force, mechanical force extrusion, and vertical rhythm for massage to promote the dredging of meridians and blood circulation in the human body, maintain the balance of yin and yang in the body, and are suitable for white-collar workers who sit for long periods of work, helping people relax muscles and relieve fatigue.

[0004] In the existing rhythm structure, the upper frame assembly is generally installed on the base assembly through four V-shaped sheet metals. The upper frame assembly is directly driven to rhythm by an eccentric drive assembly arranged on the base assembly. Since the four V-shaped sheet metals are all independent, when the loads on the four corners of the upper frame assembly are uneven, it will affect the synchronism of the movement of the four V-shaped sheet metals, and abnormal sounds will occur during the rhythm, and the support stability is not good.

[0005] In view of this, there is an urgent need for a vertical rhythm device to solve the above problems. Summary of the Invention

[0006] In order to help solve the problems existing in the prior art, a vertical rhythm device provided in this application adopts the following technical solutions: including: a base assembly, two swing shaft assemblies, a drive assembly, a synchronization assembly, and an upper frame assembly. The base assembly includes a base;

[0012] In a specific feasible embodiment, U-shaped plates are provided at both ends of the connecting rod, and the U-shaped plates are clamped on both sides of the second connecting end.

[0013] In a specific feasible embodiment, the driving assembly includes a rotating shaft, an eccentric wheel, a multi-wedge belt, and a power assembly. The rotating shaft is horizontally arranged on the base, the eccentric wheel is sleeved on the rotating shaft, and the power assembly is used to drive the rotating shaft to rotate;

[0014] An installation member is provided on the annular side of one of the swing shafts, a connecting shaft is provided on the installation member, and the multi-wedge belt is sleeved on the connecting shaft and the eccentric wheel.

[0015] In a specific feasible embodiment, the power assembly includes a motor, a transmission belt, and a pulley. The motor is arranged on the base, the pulley is sleeved on the rotating shaft, and the transmission belt is sleeved on the pulley and the output end of the motor.

Since the four connecting members move synchronously and the four connecting members are respectively connected to the four bottom corners of the upper frame assembly, when the loads at the four corners are different, it will not affect the rhythm of the upper frame assembly, reducing the probability of abnormal noise during the movement of the upper frame assembly, and further improving the stability of the support.

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0030] The following will be further described in detail with reference to the attached Figures 1-6 The present utility model will be further described in detail.

[0031] Refer to Figures 1-3, a vertical rhythm device, comprising: a base assembly 1, two swing shaft assemblies 2, a drive assembly 3, a synchronization assembly, and an upper frame assembly 4. The base assembly 1 includes a base 11; the two swing shaft assemblies 2 are respectively disposed on both sides of the base 11. The swing shaft assembly 2 includes a horizontally disposed swing shaft 21 and two connecting members 22 respectively disposed at both ends of the swing shaft 21. The connecting members 22 are both connected to the upper frame assembly 4; the synchronization assembly is used to synchronously rotate the two swing shafts 21; the drive assembly 3 is used to drive the swing shaft 21 to rotate. Thus, by driving the two swing shafts 21 to rotate synchronously by the drive assembly, the four connecting members 22 disposed at both ends of the two swing shafts 21 rotate about the swing shaft 21 (the connecting members 22 on the same swing shaft 21 are symmetrically welded at both ends of the swing shaft, which can ensure the synchronous movement of the connecting members 22), causing the height at the connection between the connecting member 22 and the upper frame assembly to change, and further causing the upper frame assembly 4 to rhythm in the vertical direction. Since the four connecting members 22 move synchronously and the four connecting members 22 are respectively connected to the four bottom corners of the upper frame assembly, when the loads at the four corners are different, it will not affect the rhythm of the upper frame assembly, reducing the probability of abnormal noise during the movement of the upper frame assembly and further improving the stability of the support.

[0032] Referring to Figures 2-4 , the synchronization assembly includes two connecting rods 5. The two ends of the two connecting rods 5 are respectively connected to the same-side connecting members 22 on different swing shafts 21. Thus, it ensures the synchronous movement of the four connecting members 22 and guarantees the stability of the movement of the upper frame assembly 4.

[0033] Referring to Figures 3-4 , in order to better connect with the upper frame assembly 4 and the connecting rod 5, the connecting member 22 includes a first connection end and a second connection end. The first connection end and the second connection end are respectively located in different directions on the circumferential side of the swing shaft 21. The first connection end is connected to the upper frame assembly 4, and the second connection end is connected to the corresponding connecting rod 5. That is to say, the connecting member 22 is preferably in a V shape. The two ends of the connecting member 22 are respectively the first connection end and the second connection end, and are respectively rotatably connected to the upper frame assembly 4 and the connecting rod 5. In order to make the connection between the connecting rod 5 and the second connection end more stable, U-shaped plates 51 are provided at both ends of the connecting rod 5, and the U-shaped plates 51 are clamped on both sides of the second connection end.

[0034] Referring to Figures 3-6, the driving assembly 3 includes a rotating shaft 31, an eccentric wheel 32, a multi-wedge belt 33 and a power assembly. The rotating shaft 31 is horizontally arranged on the base 11, the eccentric wheel 32 is sleeved on the rotating shaft 31, and the power assembly is used to drive the rotating shaft 31 to rotate; an installation member 23 is arranged on the side of one of the swing shafts 21, a connecting shaft 24 is arranged on the installation member 23, and the multi-wedge belt 33 is sleeved on the connecting shaft 24 and the eccentric wheel 32. In this way, by the rotation of the rotating shaft 31, the eccentric wheel 32 rotates, so that the connecting shaft 24 connected to the eccentric wheel 32 through the multi-wedge belt 33 generates a displacement in the horizontal direction, and then the installation member 23 moves with the swing shaft 21 as the axis, causing the swing shaft 21 to rotate reciprocally, causing the plurality of connecting members 22 to swing, and further causing the upper frame assembly 4 to move upward. Combining with the gravity of the upper frame assembly 4 (the gravity of the upper frame assembly 4 causes the upper frame assembly 4 to move downward), so reciprocally, the upper frame 4 makes vertical rhythmic motions.

[0035] Refer to Figures 3-4 , the power assembly includes a motor 34, a transmission belt 35 and a pulley 36. The motor 34 is arranged on the base 11, the pulley 36 is sleeved on the rotating shaft 31, and the transmission belt 35 is sleeved on the pulley 36 and the output end of the motor 34. In this way, the motor 34 provides power to make the transmission belt 35 move and the pulley 36 rotate, so as to make the rotating shaft 31 rotate. And in order to facilitate the control of the rotation speed of the motor 34, the power assembly further includes a code disk arranged on the motor 34.

[0036] Refer to Figures 1-3 , in order to facilitate the connecting member 22 to drive the upper frame assembly 4 to move, the upper frame assembly 4 includes an installation frame 41 and a plurality of connecting plates 42 arranged at the bottom of the installation frame 41. The first connection end is connected to the corresponding connecting plate 42. In this way, it is convenient to connect the installation frame 41 with the plurality of connecting members 22.

[0037] Further optimized, refer to Figure 1 , the base assembly 1 further includes a plurality of footpad suction cups 12 arranged at the bottom of the base 11, so that the base 11 can be stably placed on the ground or platform.

[0038] Further optimized, in order to make the movement of the upper frame assembly 4 stable and reduce the impact force on the base assembly 1, the base assembly 1 further includes a plurality of elastic rubber columns 13 arranged on the base 11. In this way, when the upper frame assembly 4 falls, it touches the rubber columns 13, buffers the movement of the upper frame assembly 4, and the elastic force of the rubber columns 13 applies a partial upward movement force to the upper frame assembly 4.

[0039] Further optimized, as Figure 4 shown, points A, B, and C in the figure form a triangle, which can increase the stability of the entire mechanism.

[0040] In summary: By driving the two swing shafts 21 to rotate synchronously through the driving component, the height at the connection between the connecting member 22 and the upper frame component changes, thereby causing the upper frame component 4 to rhythmically move in the vertical direction. Since the four connecting members 22 move synchronously and the four connecting members 22 are respectively connected to the four bottom corners of the upper frame component, when the loads at the four corners are different, it will not affect the rhythmic movement of the upper frame component, reducing the probability of abnormal noise occurring during the movement of the upper frame component, and further improving the stability of the support.

After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
