Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and in particular to a vertical rhythmic mechanism and a rhythmic training device. Background Art

[0002] With the development of society, people's pace of life is getting faster and faster. In the fast-paced work and study process, people's physical condition will naturally encounter more and more problems. Fatigue, worry, anxiety and other negative conditions gradually bring people into a sub-healthy state, and even lead to diseases. This prompts people to do various fitness exercises. However, the fast-paced study and work also limit people's fitness time. In this way, various fitness equipment came into being, such as rhythmic fitness equipment. After the mechanical force is used to push the human body up, when the mechanical force stops, the human body naturally falls down due to gravity. Through the rapid frequency of 5-30 vibrations per second, a special type of impact is produced on the body, which plays a training role.

At present, there is a way to solve the problem of horizontal movement by adding vertical guide pillars, which can be realized in structural principle, but in the simulation process, the vertical guide pillars are subjected to horizontal axial force, so there are problems such as large movement noise and poor structural reliability.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] The present embodiment provides a vertical rhythm mechanism, which includes: a base, a rhythm frame, a driving device, a limit connection assembly and an eccentric transmission assembly. The driving device is arranged on the base, the rhythm frame is movably connected to the base via the limit connection assembly, and the driving device is driven and cooperated with the rhythm frame via the second eccentric transmission assembly. The limit connection piece is used to move the rhythm frame in a straight line direction.

[0026] Please refer to Figure 1 and Figure 2 As shown, the base 100 and the rhythm frame 200 are both welded with square steel to form a frame structure, and the base 100 is used to support the entire vertical rhythm device. The rhythm frame 200 is interactively connected with the base 100 through the limit connection assembly 400, and the rhythm frame 200 is driven and matched with the driving device 300 through the eccentric transmission assembly 500. The eccentric transmission assembly 500 can adopt the same eccentric block transmission mechanism or connecting rod transmission mechanism as the relevant rhythm mechanism, and the driving device 300 can drive the rhythm frame 200 to generate rhythm through the eccentric transmission assembly 500. The limit connection assembly 400 is connected to the rhythm frame 200, ensuring the stability of the rhythm frame 200 while limiting the rhythm frame 200, so that the rhythm frame 200 only moves in the vertical direction, thereby ensuring that the rhythm frame 200 only generates vertical rhythm. It can be understood that no matter whether it is an eccentric block transmission mechanism or a connecting rod transmission mechanism, it is easy to generate horizontal force during the rhythm, causing the rhythm frame 200 to move in the horizontal direction, which not only affects the rhythm effect, but also has problems such as poor rhythm stability and noise during the rhythm. In this embodiment, the base 100 and the rhythm frame 200 are connected by a limiting connection component 400 to limit the moving direction of the rhythm frame 200, so as to ensure that the rhythm frame 200 always rhythms in the vertical direction, thereby improving the stability and rhythm effect of the rhythm frame 200.

[0027] Optionally, in some possible embodiments, the position limiting connection assembly 400 includes a first transmission rod 401 and a second transmission rod 402. The first transmission rod 401 is rotatably connected to the base 100, the other end of the first transmission rod 401 is rotatably connected to one end of the second transmission rod 402, and the movable end of the second transmission rod 402 is rotatably connected to the rhythm frame 200.

[0028] Please refer to Figure 2As shown, the connection assembly includes a first transmission rod 401 and a second transmission rod 402 intersecting each other, one end of the first transmission rod 401 away from the second transmission rod 402 is hinged to the base 100, and a section of the second transmission rod 402 away from the first transmission rod 401 is hinged to the rhythm frame 200, and the first transmission rod 401 and the second transmission rod 402 are used to connect the base 100 and the rhythm frame 200 to prevent the rhythm frame 200 from being separated from the base 100. At the same time, the hinge structure between the first transmission rod 401 and the second transmission rod 402 ensures that the rhythm frame 200 can be moved back and forth in the vertical direction by folding the first transmission rod 401 and the second transmission rod 402. At the same time, the second transmission rod 402 is relatively fixed with the direction of the rotation axis of the second transmission rod 402, and the rhythm frame 200 cannot move in the direction perpendicular to the rotation axis of the first transmission rod 401 and the second transmission rod 402, thereby limiting the rhythm frame 200.

[0029] Optionally, in some possible embodiments, the eccentric transmission assembly 500 includes a driving shaft 501 and an eccentric swing block 502, the driving shaft 501 is rotatably arranged on the base 100, one end of the eccentric swing block 502 is connected to the driving shaft 501, and the other end of the eccentric swing block 502 is rotatably connected to the rhythm frame 200, the driving shaft 501 is driven and cooperated with the output shaft of the driving device 300, and the rotating shaft of the eccentric swing block 502 is perpendicular to the rotating shafts of the first transmission rod 401 and the second transmission rod 402.

[0030] Please refer to Figure 2 As shown, one or more driving shafts 501 are provided on the base 100. When multiple driving shafts 501 are provided, the multiple driving shafts 501 are parallel to each other, and the driving shafts 501 are perpendicular to the rotation axes of the first transmission rod 401 and the second transmission rod 402. One or more eccentric swing blocks 502 can be provided on the driving shaft 501, and the movable end of the eccentric swing block 502 is hinged to the rhythm frame 200. Since the driving shaft 501 is perpendicular to the rotation axes of the first transmission rod 401 and the second transmission rod 402, the rotation axis of the eccentric swing block 502 is perpendicular to the rotation axes of the first transmission rod 401 and the second transmission rod 402. The driving device 300 cooperates with the driving shaft 501, and when the driving shaft 501 drives the eccentric swing block 502 to rotate, it can drive the rhythm frame 200 to generate rhythm. Please refer to Figure 2As shown, the preset vertical direction is the Z direction, the length direction of the base 100 is the X direction, and the direction perpendicular to the base 100 is the Y direction. It can be understood that the eccentric swing block 502 rotates along the rotation axis parallel to the X direction. When rotating, in addition to the movement in the vertical direction, it also causes the rhythm frame 200 to move in the Y direction. The first transmission rod 401 and the second transmission rod 402 rotate along the rotation axis parallel to the Y direction, so that the rhythm frame 200 cannot move in the Y direction. The eccentric swing block 502 cooperates with the first transmission rod 401 and the second transmission rod 402 to work together. When the driving force output by the driving device 300 is converted into the rhythm effect of the rhythm frame 200, it is limited from the X and Y directions respectively to ensure that the rhythm frame 200 can only rhythm in the vertical direction, thereby improving the stability and rhythm effect of the rhythm frame 200.

[0031] Optionally, in some possible embodiments, a plurality of eccentric swing blocks 502 are arranged at intervals on the driving shaft 501, and the plurality of eccentric swing blocks 502 are hinged to the rhythm frame 200 to form a plurality of driving points, thereby ensuring that different parts of the rhythm frame 200 are all subjected to the driving force of the eccentric swing blocks 502, thereby improving the stability of the rhythm frame 200 during rhythm.

[0032] Optionally, in some possible embodiments, a plurality of groups of position limiting connection assemblies 400 are provided on the base 100, each position limiting connection assembly 400 includes a first transmission rod 401 and a second transmission rod 402, and the rotation axes of the first transmission rods 401 of the plurality of position limiting connection assemblies 400 are parallel to each other.

[0033] Please refer to Figure 2 As shown, the rhythm frame 200 is movably connected to the base 100 through a plurality of position-limiting connection components 400, thereby improving the stability of the rhythm frame 200. Each position-limiting connection component 400 is composed of a first transmission rod 401 and a second transmission rod 402, and the structures are completely the same and can be replaced with each other, thereby ensuring the universality of the original parts and reducing the mold opening and manufacturing costs during production. In order to avoid the interference of the plurality of position-limiting connection components 400 and affect the movement of the rhythm frame 200, the rotation axes of the plurality of first transmissions are parallel to each other.

[0034] Optionally, in some possible embodiments, a plurality of groups of position limiting connection components 400 are arranged in pairs on the base 100, and a linkage rod 600 is arranged between two groups of position limiting connection components 400 arranged in pairs, and the linkage rod 600 is used to drive the two groups of position limiting connection components 400 to move synchronously.

[0035] Please refer to Figure 2As shown, multiple connection components are symmetrically arranged on the base 100 in pairs, and multiple connection components are connected to the rhythm frame 200 from both sides to ensure the stability of the rhythm frame 200. A linkage rod 600 is arranged between the two groups of limit connection components 400 arranged in pairs. Specifically, one end of the first transmission rod 401 is hinged to the base 100, and the other end of the first transmission rod 401 is hinged to the linkage rod 600 and the second transmission rod 402 at the same time. The two groups of first transmission rods 401 and second transmission rods 402 connected by the linkage rod 600 rotate synchronously to ensure the stability of both sides of the rhythm frame 200. It can be understood that the driving device 300 is driven and connected to the eccentric transmission component 500, so that the limit connection component 400 only acts as a driven mechanism and follows the rhythm frame 200. Therefore, the linkage rod 600 is arranged to make the first transmission rods 401 and the second transmission rods 402 on both sides of the rhythm frame 200 rotate synchronously to prevent the rhythm frame 200 from tipping over.

[0036] Optionally, in some possible embodiments, the driving mechanism includes a driving motor 301 and a reduction transmission mechanism, and the output shaft of the driving motor 301 is drivingly connected to the eccentric transmission assembly 500 via the reduction transmission mechanism.

[0037] The driving motor 301 is connected to the driving shaft 501 of the eccentric transmission assembly 500 via a reduction transmission mechanism, and the rotation speed of the driving shaft 501 is controlled by the reduction transmission mechanism, thereby ensuring that the rhythm frequency of the rhythm frame 200 has good use comfort.

[0038] Optionally, in some possible embodiments, the reduction transmission mechanism includes a first pulley 302, a second pulley 303 and a transmission belt 304, the first pulley 302 is arranged on the output shaft of the drive motor 301, the second pulley 303 is connected to the eccentric transmission assembly 500, and the transmission belt 304 is arranged on the first pulley 302 and the second pulley 303.

[0039] Please refer to Figure 2 As shown, the second pulley 303 is arranged on the driving shaft 501 of the eccentric transmission assembly 500, and the driving motor 301 is connected to the driving shaft 501 through a belt transmission mechanism. On the one hand, the belt transmission mechanism has a simple structure and low cost, and the starting process of the belt transmission mechanism is relatively smooth, avoiding sudden start-up and causing discomfort to the user. On the other hand, the belt transmission mechanism has an overload protection function. When the bearing weight of the rhythm frame 200 exceeds the limit weight, the belt transmission mechanism will idle, avoiding damage to the driving motor 301 and ensuring the safety of the driving motor 301.

[0040] Optionally, see Figure 3 As shown, in some possible embodiments, a rotation bearing 700 is disposed at a connection between the first transmission rod 401 and the base 100 and at a connection between the first transmission rod 401 and the second transmission rod 402 .

[0041] The rotating bearing 700 can adopt commercially available roller bearings or other bearings to reduce the friction between the connection between the first transmission rod 401 and the base 100 and the connection between the first transmission rod 401 and the second transmission rod 402, further improve the stability during the rhythm and reduce the noise.

[0042] Optionally, in some possible embodiments, a support protector is provided at the bottom of the base 100, and the support protector 800 is used to support the base 100. The support protector can adopt a support suction cup, which adsorbs the ground through the support suction cup, thereby fixing the base 100 to prevent the base 100 from displacement during the rhythmic process.

[0043] Optionally, in some possible embodiments, the supporting protective member may also be made of soft materials such as rubber or silicone, which can protect the base 100 while reducing noise and improving usage comfort.

[0044] The embodiment of the present invention further provides a rhythm training device, which includes a support plate 900 and the rhythm mechanism in the above embodiment, and the support plate 900 is arranged on a rhythm frame 200 perpendicular to the rhythm mechanism.

[0045] Please refer to Figure 4 As shown, the rhythmic training device adopts the rhythmic mechanism provided in the above embodiment to ensure that the support plate 900 only rhythmically moves in the vertical direction, the rhythmic training effect is good, and the entire rhythmic training device has high stability.

[0046] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0047] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
