Description

Technical Field

[0001] The present invention relates to the technical field of rhythm machines, and in particular to a rhythm machine capable of performing compound movements. Background Art

[0002] A rhythm machine is a device that produces regular passive movements through fixed-frequency vibrations. Its core principle is to use the physical stimulation of gravity on the musculoskeletal and nervous systems, thereby affecting the endocrine and other physiological systems to achieve the effect of improving health.

[0003] The existing rhythm machines have a single movement mode. When people are on the rhythm machines, they can only perform separate horizontal reciprocating motion or vertical lifting motion, and people's user experience is poor. For example, the Chinese utility model patent disclosed on July 5, 2024, with the announcement number CN221265684U, is a horizontal rhythm bed. The rhythm mechanism in the rhythm device drives the rhythm frame to reciprocate horizontally relative to the support frame, thereby driving the bed frame connected to the rhythm frame to reciprocate horizontally, so that the user can achieve rhythmic exercise in a lying state, which can effectively meet the user's usage needs. However, people's movement amplitude is low in this exercise mode, and the exercise effect is poor.

[0004] There is also a Chinese invention patent published on June 21, 2019, with publication number CN109907933A, which is a vertical rhythm machine. The application of the eccentric wheel connecting rod and two bearings can cleverly convert the rotational motion of the eccentric wheel into a simple up and down vertical linear motion. The rhythm machine of the present invention is clever and efficient, safe, stable and comfortable, and perfectly realizes the drive of simple up and down vertical rhythm. However, people's user experience is poor. Summary of the Invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0030] like Figure 1-Figure 3 As shown, the present invention provides a rhythm machine capable of compound motion, comprising: a top plate 17, a support member 13, a first connecting plate 4, a second connecting plate 5, a lifting support transmission mechanism 7, a first transmission assembly, a second transmission assembly and a driving member 6;

[0031] The support member 13 is hinged below the top plate 17;

[0032] Two first connecting plates 4 are symmetrically hinged on one side of the bottom surface of the support member 13;

[0033] Two second connecting plates 5 are symmetrically fixed on the other side of the bottom surface of the support member 13;

[0034] The lifting support transmission mechanism 7 is hinged to the first connecting plate 4 and the second connecting plate 5. The lifting support transmission mechanism 7 is used to synchronize the movement of the first connecting plate 4 and the second connecting plate 5 along a direction perpendicular to the top plate 17. Here, it only refers to the stroke, not the movement trajectory;

[0035] The first transmission assembly includes a first rotating shaft 2 and an eccentric rotating shaft 3. The eccentric rotating shaft 3 is eccentrically arranged at one end of the first rotating shaft 2. One end of the eccentric rotating shaft 3 is rotatably connected to the end of the first connecting plate 4 away from the top plate 17.

[0036] The second transmission assembly includes a second rotating shaft 10 and a cam 11. The second rotating shaft 10 is rotatably connected to the cam 11 through an eccentric bearing. One end of the cam 11 is hinged to the bottom surface of the top plate 17.

[0037] The driving member 6 is used to drive the first rotating shaft 2 and the second rotating shaft 10 to rotate. When the second rotating shaft 10 rotates, the top plate 17 rotates around the hinge with the support member 13;

[0038] When in use, by starting the driving member 6, it drives the first rotating shaft 2 and the second rotating shaft 10 to rotate. The rotation of the first rotating shaft 2 drives the eccentric rotating shaft 3 to rotate. Under the action of the lifting support transmission mechanism 7, the eccentric rotating shaft 3 drives the first connecting plate 4 to swing in an arc and move up and down at the same time, and the lifting support transmission mechanism 7 drives the second connecting plate 5 to follow the first connecting plate 4 to move up and down in the vertical direction. At the same time, the rotation of the second rotating shaft 10 will drive the cam 11 to swing in an arc and move up and down at the same time, so that the cam 11 drives the top plate 17 to swing back and forth around the hinge with the support member 13, so that when a person is on the top plate 17, the person can perform left and right reciprocating tilting and swinging and reciprocating motion in the vertical direction. Compared with the existing rhythmic motor that can only perform separate horizontal reciprocating motion or vertical lifting motion, this composite rhythmic motor can simultaneously enable people to perform left and right reciprocating tilting and swinging and motion in the vertical direction, and people have a better user experience.

[0039] like Figure 1 and Figure 2 As shown, there are two lifting support transmission mechanisms 7, each of which includes a first transmission member 71, a first connecting rod 72, a second connecting rod 73, a second transmission member 74, a first base 75 and a second base 76. One end of the first transmission member 71 is hinged to the end of the first connecting plate 4 away from the support member 13, and one end of the second transmission member 74 is hinged to the end of the second connecting plate 5 away from the support member 13. Both ends of the first connecting rod 72 are hinged to the first transmission member 71 and the second transmission member 74 respectively. One end of the second connecting rod 73 is hinged to the middle part of the first transmission member 71, and the other end is hinged to the first base 75. The middle part of the second transmission member 74 is hinged to the second base 76. The first transmission member 71 is located above the second transmission member 74.

[0040] The first transmission member 71 and the second transmission member 74 are connected end to end by a first connecting rod 72. A rotation fulcrum is provided at the midpoint between the first transmission member 71 and the second transmission member 74 (supported by a first base 75 and a second base 76, respectively), forming an equal-arm lever. When the first rotating shaft 2 rotates, due to the lever principle, the left end of the first transmission member 71 and the right end of the second transmission member 74 have the same vertical movement direction, thereby realizing the up and down movement of the top plate 17.

[0041] Specifically, when the driving member 6 drives the first rotating shaft 2 to rotate, the first rotating shaft 2 drives the eccentric rotating shaft 3 to rotate, and the eccentric rotating shaft 3 drives the first connecting plate 4 to swing and move up and down at the same time, and the eccentric rotating shaft 3 will drive the first transmission member 71 to swing while its two ends move up and down. At this time, the second connecting rod 73 swings around the hinge between it and the first base 75, and the first transmission member 71 drives the first connecting rod 72 to swing and move up and down. The first connecting rod 72 then drives the second transmission member 74 to swing left and right around the hinge between it and the second base 76, so that the second transmission member 74 can finally drive the second connecting plate 5 to reciprocate up and down, so that the second connecting plate 5 and the first connecting plate 4 have the same movement stroke in the vertical direction, thereby realizing the up and down reciprocating movement of the top plate 17.

[0042] like Figure 2 As shown, the driving member 6 is a dual-axis motor, a first transmission wheel 8 is fixed to the outer surface of the first rotating shaft 2, and a second transmission wheel 9 is fixed to the outer surface of the second rotating shaft 10. The two output ends of the dual-axis motor are respectively connected to the first transmission wheel 8 and the second transmission wheel 9 through a transmission belt. In this way, the first rotating shaft 2 and the second rotating shaft 10 can be driven to rotate simultaneously by a single dual-axis motor;

[0043] Here, the first rotating shaft 2 and the second rotating shaft 10 are respectively located on both sides of the driving member 6, and the first transmission wheel 8 and the second transmission wheel 9 are located at diagonally opposite corners of the base plate 1. The spatial position arrangement is more reasonable, and the rhythm machine ensures that the overall weight distribution is relatively uniform.

[0044] A one-way bearing (not shown) is provided between the first transmission wheel 8 and the first rotating shaft 2;

[0045] It is defined here that when the driving member 6 is started in the forward direction, it can simultaneously drive the first rotating shaft 2 and the second rotating shaft 10 to rotate, so that the top plate 17 can simultaneously perform left and right reciprocating tilting and swinging and reciprocating motion in the vertical direction. At this time, when the driving member 6 is started in the reverse direction, it will only drive the second rotating shaft 10 to rotate, thereby only driving the top plate 17 to perform left and right reciprocating tilting and swinging, so that the motion state of the rhythm machine can be adjusted according to people's needs, increasing the diversity of people's choices when exercising.

[0046] like Figure 1 and Figure 2 As shown, it also includes a base plate 1, a first base 75 and a second base 76 are fixed to the top surface of the base plate 1, and two first support plates 15 and two second support plates 16 are provided on the top surface of the base plate 1. A first rotating shaft 2 is rotatably provided on the two first support plates 15, and the first rotating shaft 2 is located between the two first support plates 15. The eccentric rotating shaft 3 is movable out of the side wall of the first support plate 15, thereby facilitating the connection between the eccentric rotating shaft 3 and the first connecting plate 4 and the first transmission member 71. A second rotating shaft 10 is rotatably provided between the two second support plates 16;

[0047] The bottom plate 1 is provided to support the first base 75 , the second base 76 , the first support plate 15 and the second support plate 16 , so that they form a complete whole with the top plate 17 , the support member 13 and the lifting support transmission mechanism 7 .

[0048] like Figure 2 and Figure 3 As shown, the support member 13 is two support rods, one end of the bottom surface of the two support rods is hinged with a first connecting plate 4, and the other end is fixedly installed with a second connecting plate 5;

[0049] By configuring the support member 13 as two support rods, a first connecting plate 4 and a second connecting plate 5 are provided on the bottom surface of each support rod, thus avoiding the need for a whole plate for support, reducing the overall weight and saving more materials.

[0050] like Figure 2 and Figure 3 As shown, the center positions of the two support rods are hinged with a first hinge seat 12, one end of the first hinge seat 12 is fixed to the center position of the bottom surface of the top plate 17, and the second hinge seat 14 is fixedly installed on one side of the bottom surface of the top plate 17. The second hinge seat 14 is hinged to the cam 11;

[0051] By arranging the first hinge seat 12 at the center of the support rod and the top plate 17, on the one hand, the left and right swing amplitudes of the top plate 17 are made the same, making people more coordinated when exercising. On the other hand, when the hinge seat is located between the two plates, the support span of the pin is significantly shortened, and the pin is similar to a short-span beam. Under the same load, the bending moment and bending deformation of the pin arranged in the middle are greatly reduced, which can effectively prevent the pin from bending, deformation or even breaking, and has obvious advantages especially under high load or impact load.

[0052] By setting the first articulated seat 12 and the second articulated seat 14, the articulated seat itself is a reinforcing component, which can significantly increase the local stiffness and strength at the connection point, resist the bending moment, shear force and possible impact load generated by the articulated movement, and at the same time, the articulated seat design usually has a large contact area and a sturdy structure, which can distribute the load from the pin shaft more evenly to the support member 13. The prefabricated and precise articulated seat reduces the risk of on-site processing or positioning errors.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
