For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 7 The embodiment of the present application provides a vertical rhythm mechanism, including a frame 2, a connecting member 6, an eccentric shaft 8, an active rod 7, a first driven rod 3 and a second driven rod 4. The frame 2 and the connecting member 6 are arranged opposite to each other, and the first driven rod 3 and the second driven rod 4 are respectively located on opposite sides of the active rod 7. The frame 2 is rotatably connected to the first column 81 of the eccentric shaft 8, the first end 31 of the first driven rod, and the first end 41 of the second driven rod, respectively. The second column 82 of the eccentric shaft 8 is rotatably connected to the first end 72 of the active rod, and the connecting member 6 is rotatably connected to the second end 71 of the active rod, the second end 32 of the first driven rod, and the second end 42 of the second driven rod, respectively, so that the frame 2, the connecting member 6, the eccentric shaft 8, the active rod 7, the first driven rod 3 and the second driven rod 4 form a six-bar linkage mechanism, which is used to convert the rotational motion of the first column 81 of the eccentric shaft 8 in the circumferential direction into the reciprocating motion of the connecting member 6 in the vertical direction. The vertical rhythmic mechanism can solve the problems of large movement range and poor standing stability in the rhythmic mechanism in the form of horizontal movement in the prior art, and the complex structure and poor versatility in the rhythmic mechanism in the form of vertical movement.

[0033] It should be noted that if Figure 1 , Figure 2 , Figures 5 to 7 As shown, the first end 31 of the first driven rod is connected to the first mounting hole 21 on the frame 2 by a pin to form a first rotational pair 2131, the second end 32 of the first driven rod is connected to the first connecting hole 61 of the connecting member 6 by a pin to form a second rotational pair 3261, the second end 71 of the active rod is connected to the second connecting hole 62 of the connecting member 6 by a pin to form a third rotational pair 6271, the first end 72 of the active rod is connected to the second column 82 of the eccentric shaft 8 to form a fourth rotational pair 8272, the second mounting hole 22 on the frame 2 is connected to the first column 81 of the eccentric shaft 8 to form a fifth rotational pair 8122, the first end 41 of the second driven rod is connected to the third mounting hole 23 on the frame 2 by a pin to form a sixth rotational pair 4123, and the second end 42 of the second driven rod is connected to the third connecting hole 63 of the connecting member 6 by a pin to form a seventh rotational pair 4263.

[0034] In this way, the frame 2, the connecting member 6, the eccentric shaft 8, the active rod 7, the first driven rod 3 and the second driven rod 4 can form a six-bar linkage through the above seven rotational pairs, so that the rotational motion of the first cylinder 81 of the eccentric shaft 8 in the circumferential direction is converted into the reciprocating motion of the connecting member 6 in the vertical direction through the six-bar linkage. Specifically, the working principle of the above six-bar linkage is as follows: since the centers of the first cylinder 81 and the second cylinder 82 of the eccentric shaft 8 do not coincide, but there is a certain distance (that is, there is a fifth rotational pair 8122), and the connecting member 6 is rotationally connected with the first cylinder 81 of the eccentric shaft 8 through the fourth rotational pair 8272, and the other rotational pairs of the six-bar linkage (including the first rotational pair 2131, the second rotational pair 3261, the third rotational pair 6271, the sixth rotational pair 4123 and the seventh rotational pair 4263) constrain the action, therefore, the reciprocating motion of the connecting member 6 in the vertical direction can be realized.

[0035] Compared with the prior art, the vertical rhythmic mechanism provided in the present application can convert the rotational motion of the first column 81 of the eccentric shaft 8 in the circumferential direction into the reciprocating motion of the connecting member 6 in the vertical direction through a six-link mechanism. The structure is simple and reliable. Moreover, during the movement of the connecting member 6, it can always remain horizontal. Therefore, it can increase the user's standing stability and prevent the user from easily falling during use, thereby increasing the user's exercise comfort and training effect during use.

[0036] As an implementation method, Figure 3 , Figure 5 and Figure 6As shown, the vertical rhythm mechanism also includes a driving mechanism, which is connected to the first column 81 of the eccentric shaft 8, and is used to drive the first column 81 of the eccentric shaft 8 to rotate in a circumferential direction to provide driving force for the rotational movement of the eccentric shaft 8.

[0037] As an implementation method, Figure 3 , Figure 5 and Figure 6 As shown, the driving mechanism includes a driving member 11, and the output shaft of the driving member 11 is connected to the first column 81 of the eccentric shaft 8. For example, the driving member 11 is a motor, which is fixedly mounted on the frame 2, and the output shaft of the motor is connected to the first column 81 of the eccentric shaft 8, so that the first column 81 of the eccentric shaft 8 is driven to rotate by the rotation of the output shaft of the motor.

[0038] As an implementation method, Figure 3 , Figure 5 and Figure 6 As shown, the driving mechanism also includes a driving wheel 10, a driven wheel 5 and a transmission belt 9 mounted on the driving wheel 10 and the driven wheel 5, so that the driving wheel 10, the driven wheel 5 and the transmission belt 9 form a synchronous belt transmission mechanism, the driving wheel 10 is mounted on the output shaft of the driving member 11, the driven wheel 5 is mounted on the first column 81 of the eccentric shaft 8, and the rotation radius of the driving wheel 10 is smaller than the rotation radius of the driven wheel 5, so that the high-speed rotation of the driving member 11 and the driving wheel 10 is converted into the low-speed rotation of the driven wheel 5 and the eccentric shaft 8 through the synchronous belt transmission mechanism.

[0039] Specifically, when the driving member 11 rotates, since the driving wheel 10 is fixed on the output shaft of the driving member 11, the driving wheel 10 can rotate together with the driving member 11. Since the driving wheel 10 and the driven wheel 5 are connected by the transmission belt 9, and the driven wheel 5 is fixed on the first column 81 of the eccentric shaft 8, and the first column 81 of the eccentric shaft 8 is rotatably installed on the frame 2 through the fifth rotating pair 8122, the eccentric shaft 8 can rotate together with the driven wheel 5.

[0040] As an implementable embodiment, the vertical rhythm mechanism further includes a control module, which is electrically connected to the driving member 11 and is used to control the operation of the driving member 11, thereby regulating the start, stop and rotation speed of the driving member 11. As an implementable embodiment, the vertical rhythm mechanism further includes a power supply module, which is electrically connected to the driving member 11 and is used to provide power to the driving member 11 to ensure the normal operation of the driving member 11 and the six-bar linkage.

[0041] For example, in some embodiments, the control module and the power supply module can be installed on the rack 2 respectively; or, in other embodiments, such as Figure 3 , Figure 5 and Figure 6As shown, the control module and the power supply module can be integrated together, for example, integrated into a power supply box 12 and installed on the rack 2 as a whole.

[0042] As an implementation method, Figure 3 and Figure 4 As shown, the number of the six-bar linkage is at least one. When the number of the six-bar linkage is two, the two six-bar linkages are axially symmetrically arranged along the center line of the connecting member 6 in the horizontal direction to improve the stability of the force applied to the connecting member 6 in the horizontal direction.

[0043] As an implementation method, Figures 3 to 5 As shown, the connecting member 6 is provided with a mounting structure 64, which is used to be fixedly connected to a rhythmic body (such as a rhythmic sofa, a rhythmic bed, etc.). For example, in this embodiment, the mounting structure 64 is a threaded hole, so that the rhythmic body and the connecting member 6 can be mounted together through the mutual cooperation of the fastener and the mounting structure 64, so that the rhythmic body is driven to move synchronously in the vertical direction through the connecting member 6.

[0044] As an implementation method, Figures 3 to 5 As shown, a foot pad 1 is provided on one side of the frame 2 away from the connecting member 6, and the number of the foot pads 1 is at least two, so as to support and cushion the frame 2 through the foot pads 1, thereby improving the stability of the frame 2 and the vertical rhythm mechanism.

[0045] The embodiment of the present application also provides a rhythmic device, including a rhythmic body and the vertical rhythmic mechanism described above, wherein the rhythmic body is fixedly connected to the connecting piece 6 of the vertical rhythmic mechanism, so that the vertical rhythmic mechanism can be applied to various rhythmic bodies through modularization, and together form a corresponding rhythmic device. Since the structure and beneficial effects of the vertical rhythmic mechanism have been described in detail in the above embodiments, they will not be repeated here.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
