Compoundable motion rhythm machine

Abstract

This utility model discloses a composite motion rhythmic device, relating to the field of rhythmic device technology. A drive unit rotates a first and second rotating shaft. The rotation of the first rotating shaft drives an eccentric rotating shaft. Under the action of a lifting support transmission mechanism, the eccentric rotating shaft causes the first connecting plate to swing in an arc while moving up and down. Simultaneously, the lifting support transmission mechanism causes the second connecting plate to follow the first connecting plate in vertical up-and-down movement. The rotation of the second rotating shaft also causes a cam to swing in an arc while moving up and down, thus causing the cam to drive the top plate to swing back and forth around the hinge point with the support member. Therefore, when a person is on the top plate, they can perform left-right back-and-forth swinging and vertical back-and-forth movements. Compared to existing rhythmic devices that can only perform single horizontal back-and-forth or vertical up-and-down movements, this composite rhythmic device can simultaneously enable people to perform left-right back-and-forth swinging and vertical movements, resulting in a better user experience.

Description

Technical Field

[0001] This utility model relates to the field of rhythmic motion technology, and in particular to a rhythmic motion device capable of compound motion. Background Technology

[0002] A rhythmic motion device is a device that generates regular passive motion through fixed-frequency vibration. Its core principle is to use gravity to physically stimulate the musculoskeletal and nervous systems, thereby affecting the endocrine and other physiological systems to improve health.

[0003] Existing rhythmic motion devices offer limited movement options. When a person is on the device, they can only perform horizontal reciprocating motion or vertical lifting motion, resulting in a poor user experience. For example, a horizontal rhythmic bed, disclosed in Chinese Utility Model Patent No. CN221265684U on July 5, 2024, uses a rhythmic mechanism in the rhythmic device to drive the rhythmic frame to reciprocate horizontally relative to the support frame, thereby driving the bed frame connected to the rhythmic frame to reciprocate horizontally. This allows users to perform rhythmic exercises while lying down, effectively meeting their needs. However, this type of exercise results in a low range of motion and poor training effect.

[0004] Another example is a Chinese invention patent published on June 21, 2019, with publication number CN109907933A, which describes a vertical rhythm device. The application of an eccentric wheel connecting rod and two bearings can cleverly transform the rotational motion of the eccentric wheel into a simple vertical linear motion. The rhythm device of this utility model is ingenious, efficient, safe, stable and comfortable, and perfectly realizes the driving of simple vertical rhythm. However, the user experience is poor. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a rhythmic motion device that can perform compound movements, so as to solve the problem that the existing rhythmic motion devices have a single movement mode, and when people are on the rhythmic motion device, they can only perform single horizontal reciprocating motion or vertical lifting motion, resulting in a poor user experience.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rhythmic motion device capable of compound motion, comprising:

[0007] roof;

[0008] Support member, which is hinged to the bottom of the top plate;

[0009] The first connecting plate is symmetrically hinged to one side of the bottom surface of the support member;

[0010] Two second connecting plates are symmetrically fixed on the other side of the bottom surface of the support member;

[0011] A lifting support transmission mechanism is provided, wherein the lifting support transmission mechanism is hinged to both the first connecting plate and the second connecting plate, and the lifting support transmission mechanism is used to synchronize the movement of the first connecting plate and the second connecting plate along a direction perpendicular to the top plate.

[0012] The first transmission assembly includes a first rotating shaft and an eccentric rotating shaft. The eccentric rotating shaft is eccentrically located at one end of the first rotating shaft, and the one end of the eccentric rotating shaft is rotatably connected to the end of the first connecting plate away from the top plate.

[0013] The second transmission assembly includes a second rotating shaft and a cam. The second rotating shaft is rotatably connected to the cam via an eccentric bearing. One end of the cam is hinged to the bottom surface of the top plate.

[0014] A driving component is provided to drive a first rotating shaft and a second rotating shaft to rotate. When the second rotating shaft rotates, the top plate rotates about the hinge point with the support component.

[0015] Preferably, there are two lifting support transmission mechanisms. Each lifting support transmission mechanism includes a first transmission component, a first connecting rod, a second connecting rod, a second transmission component, a first base, and a second base. One end of the first transmission component is hinged to the end of the first connecting plate away from the support component. One end of the second transmission component is hinged to the end of the second connecting plate away from the support component. Both ends of the first connecting rod are hinged to the first transmission component and the second transmission component, respectively. One end of the second connecting rod is hinged to the middle of the first transmission component, and the other end is hinged to the first base. The middle of the second transmission component is hinged to the second base. The first transmission component is located above the second transmission component.

[0016] Preferably, the driving component is a dual-axis motor, with a first transmission wheel fixed to the outer surface of the first shaft and a second transmission wheel fixed to the outer surface of the second shaft. The two output ends of the dual-axis motor are respectively connected to the first transmission wheel and the second transmission wheel via a conveyor belt.

[0017] Preferably, a one-way bearing is provided between the first transmission wheel and the first rotating shaft.

[0018] Preferably, the first and second rotating shafts are located on both sides of the driving component.

[0019] Preferably, it also includes a base plate, wherein the first base and the second base are both fixed to the top surface of the base plate, and the top surface of the base plate is provided with two first support plates and two second support plates, wherein a first rotating shaft is rotatably provided on the two first support plates, and a second rotating shaft is rotatably provided on the two second support plates.

[0020] Preferably, the support member consists of two support rods, one end of the bottom surface of each support rod is hinged to a first connecting plate, and the other end of each support rod is fixedly installed with a second connecting plate.

[0021] Preferably, each of the two support rods is hinged to a first hinge seat at its center, and one end of the first hinge seat is fixed to the center of the bottom surface of the top plate.

[0022] Preferably, a second hinge seat is fixedly installed on one side of the bottom surface of the top plate, and the second hinge seat is hinged to the cam.

[0023] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0024] This invention uses a drive unit to rotate a first and a second rotating shaft. The rotation of the first rotating shaft drives the rotation of an eccentric rotating shaft. Under the action of a lifting support transmission mechanism, the eccentric rotating shaft causes the first connecting plate to swing in an arc while moving up and down. Simultaneously, the lifting support transmission mechanism causes the second connecting plate to follow the first connecting plate in vertical up and down movement. At the same time, the rotation of the second rotating shaft causes the cam to swing in an arc while moving up and down. This causes the cam to drive the top plate to swing back and forth around the hinge point with the support. Thus, when a person is on the top plate, they can perform left and right back and forth swinging motions and vertical back and forth movements. Compared with existing rhythmic motion machines that can only perform single horizontal back and forth movements or vertical up and down movements, this composite rhythmic motion machine can simultaneously enable people to perform left and right back and forth swinging motions and vertical movements, resulting in a better user experience.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0030] like Figures 1-3 As shown, this utility model provides a rhythmic device capable of compound motion, including: 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] Support member 13 is hinged to the bottom of top plate 17;

[0032] The support member 13 has two first connecting plates 4 symmetrically hinged on one side of its bottom surface;

[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 both 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 the direction perpendicular to the top plate 17. Here, only the stroke is referred to, 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 located at one end of the first rotating shaft 2, and 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 via an eccentric bearing. One end of the cam 11 is hinged to the bottom surface of the top plate 17.

[0037] The driving component 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 point with the support component 13.

[0038] In use, the drive unit 6 is activated, causing the first rotating shaft 2 and the second rotating shaft 10 to rotate. The rotation of the first rotating shaft 2 causes the eccentric rotating shaft 3 to rotate. Under the action of the lifting support transmission mechanism 7, the eccentric rotating shaft 3 causes the first connecting plate 4 to swing in an arc and move up and down. At the same time, the second connecting plate 5 follows the first connecting plate 4 and moves up and down in the vertical direction through the lifting support transmission mechanism 7. Meanwhile, the rotation of the second rotating shaft 10 causes the cam 11 to swing in an arc and move up and down. This causes the cam 11 to drive the top plate 17 to swing back and forth around the hinge with the support unit 13. Thus, when a person is on the top plate 17, they can swing back and forth left and right and move back and forth in the vertical direction. Compared with the existing rhythmic motion machines that can only perform horizontal reciprocating motion or vertical lifting motion, this composite rhythmic motion machine can enable people to swing back and forth left and right and move in the vertical direction at the same time, resulting in a better user experience.

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

[0040] The first transmission component 71 and the second transmission component 74 are connected end to end by the first connecting rod 72, and a rotation fulcrum is provided at the midpoint of the first transmission component 71 and the second transmission component 74 (supported by the first base 75 and the 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 component 71 and the right end of the second transmission component 74 have the same direction of movement in the vertical direction, which can realize the up and down movement of the top plate 17.

[0041] Specifically, when the driving component 6 drives the first rotating shaft 2 to rotate, the first rotating shaft 2 drives the eccentric rotating shaft 3 to rotate. The eccentric rotating shaft 3 drives the first connecting plate 4 to swing up and down at the same time. The eccentric rotating shaft 3 also drives the first transmission component 71 to swing up and down at both ends. At this time, the second connecting rod 73 swings around its hinge with the first base 75. The first transmission component 71 drives the first connecting rod 72 to swing up and down at the same time. The first connecting rod 72 then drives the second transmission component 74 to swing left and right around its hinge with the second base 76. This ultimately enables the second transmission component 74 to drive the second connecting plate 5 to move up and down reciprocally, so that the second connecting plate 5 and the first connecting plate 4 have the same vertical stroke, thereby realizing the up and down reciprocating motion of the top plate 17.

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

[0043] The first rotating shaft 2 and the second rotating shaft 10 are located on both sides of the driving component 6, and the first transmission wheel 8 and the second transmission wheel 9 are located diagonally opposite each other on the base plate 1. The spatial arrangement is more reasonable, and the motion mechanism ensures that the overall weight distribution is relatively uniform.

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

[0045] Here it is defined that when the forward-starting drive unit 6 can simultaneously drive the first rotating shaft 2 and the second rotating shaft 10 to rotate, the top plate 17 can simultaneously perform left-right reciprocating tilting and vertical reciprocating motion. When the reverse-starting drive unit 6 is activated, it will only drive the second rotating shaft 10 to rotate, thus only driving the top plate 17 to perform left-right reciprocating tilting. This allows the motion state of the motor to be adjusted according to people's needs, increasing the diversity of choices people can make 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, both of which are fixed to the top surface of the base plate 1. The top surface of the base plate 1 is provided with two first support plates 15 and two second support plates 16. A first rotating shaft 2 is rotatably provided on the two first support plates 15. The first rotating shaft 2 is located between the two first support plates 15. An eccentric rotating shaft 3 is movable out of the side wall of the first support plate 15, so as to facilitate the connection of the eccentric rotating shaft 3 with the first connecting plate 4 and the first transmission component 71. A second rotating shaft 10 is rotatably provided between the two second support plates 16.

[0047] By setting a base plate 1, the first base 75, the second base 76, the first support plate 15 and the second support plate 16 are supported, making them 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 consists of two support rods. One end of the bottom surface of each support rod is hinged to a first connecting plate 4, and the other end is fixedly installed with a second connecting plate 5.

[0049] By setting the support member 13 as two support rods, and setting a first connecting plate 4 and a second connecting plate 5 on the bottom surface of each support rod, it is possible to avoid using a whole plate for support, reduce the overall weight, and save more materials.

[0050] like Figure 2 and Figure 3 As shown, a first hinge seat 12 is hinged at the center of each of the two support rods. One end of the first hinge seat 12 is fixed at the center of the bottom surface of the top plate 17. A 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 setting 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 amplitude of the top plate 17 is the same, making people's body more coordinated when moving. 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 bearing arranged in the middle are drastically reduced. This can effectively prevent the pin from bending, deforming or even breaking, especially under high load or impact load.

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

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