Description

Technical Field

[0001] This invention is a rhythmic device, belonging to the field of fitness technology. Background Technology

[0002] The principle of rhythmic exercise is to simulate the movement of skipping rope, achieving the effect of full-body exercise from bottom to top and from the outside to the inside. It is a natural, safe, effective and fast way to achieve the effect of full-body exercise, and it is a passive exercise and fitness method.

[0003] Currently, during the use of a vibration motor, the device will generally vibrate to achieve the fitness operation. In order for the moving parts of the device to move normally, multiple rotating connection structures are usually designed inside the device to enable the moving parts to move.

[0004] However, friction is prone to occur at the rotating connection position during movement, which increases the probability of damage and overheating. In order to ensure that the rotating connection structure can move for a long time, it is generally necessary to lubricate the rotating connection structure regularly.

[0005] However, to prevent external objects from affecting the rotational movement, the rotating connection structure is generally designed into the equipment. There are two ways to lubricate and maintain it. One way is to disassemble the equipment shell and then use a manual lubrication device to lubricate the rotating connection structure. This makes lubrication difficult and affects the lubrication efficiency. The other way is to install an electric lubrication device in the equipment to lubricate the rotating connection structure. However, the electric lubrication device has a complex structure, which increases the equipment cost.

[0006] Content of this invention

[0007] To address the problems in the prior art, the present invention provides a rhythmic device.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a rhythmic device, including a lower cover and an upper cover movably mounted on the upper end of the lower cover. A horizontally arranged rotating shaft is movably mounted in the middle of the lower cover. Two bearing seats are symmetrically rotatably connected to the outer end of the rotating shaft, and the two bearing seats are symmetrically fixed on the bottom end of the lower cover. A driving component is mounted on the rotating shaft. The driving component is located between the two bearing seats and is located on the bottom end of the lower cover. A vibrating component is provided at both ends of the rotating shaft. The vibrating component is located inside the lower cover, and the upper end of the vibrating component extends into the upper cover and connects to the top end of the upper cover.

[0009] The lower cover has two straight cylinders symmetrically arranged inside, and the two straight cylinders are located outside the two bearing seats respectively.

The power supply is located in front of the bearing seat, and the power supply is electrically connected to the annular electromagnet, the drive device and the controller.

[0015] Furthermore, the vibration component includes an eccentric sleeve, which is mounted on the side end of the rotating shaft. The outer end of the eccentric sleeve is rotatably connected to an eccentric seat, and the cross-section of the eccentric seat is gourd-shaped. The lower end of the eccentric seat is attached to the pressure plate, and the eccentric seat is located inside the lower cover. The upper end of the eccentric seat extends into the upper cover.

[0016] An installation post is provided on the upper side of the eccentric sleeve, and the eccentric seat is rotatably connected to the outer end of the installation post. Connecting seats are provided at both the left and right ends of the installation post, and the connecting seats are fixed to the top of the inner part of the upper cover.

[0017] Furthermore, cylinders are provided at the four corners of the bottom of the inner part of the lower cover, and the cylinders are integrated with the lower cover. Vertically arranged elastic buffer columns are provided at the upper end of the cylinders.

[0018] The upper end of the elastic buffer column is provided with a mounting bracket, which is located outside the eccentric seat. Two connecting seats are provided on the upper end of the mounting bracket.

[0019] Furthermore, a box for storing lubricating oil is installed at the lower end of both straight cylinders. The two boxes are symmetrically installed on the bottom inside the lower cover, with the boxes located on the outer side of the bearing seat and on the inner side of the cylinder.

[0020] The lower end of the straight cylinder is connected to a straw with a one-way valve, and the other end of the straw is connected to the box body.

[0021] Furthermore, the oiling component includes a first annular tube, the first annular tube is installed on the inner end of the eccentric seat, and the first annular tube is located outside the eccentric sleeve, and the first annular tube is located on the lower side of the connecting seat;

[0022] The inner end of the first annular tube is equidistantly connected with multiple inclined second nozzles, which are arranged in a circular pattern and have their outlets facing the connection between the eccentric sleeve and the eccentric seat. The inner end of the first annular tube is equidistantly connected with multiple first nozzles, which are arranged in a circular pattern and have their outlets facing the connection between the bearing seat and the rotating shaft.

[0024] The lower end of the second annular pipe is connected to a connecting pipe, and the other end of the connecting pipe is connected to a first annular pipe.

[0025] Furthermore, a hose with a one-way valve is connected to the outer end of the first annular tube, and the other end of the hose is connected to the straight cylinder. An annular limiting plate is installed on the inner wall of the straight cylinder, and the annular limiting plate is located below the piston. The connection between the hose and the straight cylinder is located below the annular limiting plate.

[0026] Furthermore, the upper end of the cover is recessed downward to form a groove, and a rubber pad is installed on the groove, with the upper end of the rubber pad overlapping the upper end of the cover.

[0027] The upper end of the rubber pad is provided with multiple protrusions, and the protrusions are integrated with the rubber pad. The lower end of the cover is equipped with support seats at the four corners.

[0028] The beneficial effects of this invention are:

[0029] 1. First, connect the circuit of the annular electromagnet, which generates an attractive force between the annular electromagnet and the annular magnetic plate. When the eccentric seat moves downward, it causes the pressure plate, the round rod, the annular magnetic plate, and the piston to move downward. This is used for oiling. Under the action of the attractive force, the annular magnetic plate, the piston, the round rod, and the pressure plate move upward back to their original positions, enabling continuous oiling operations. The circuit of the annular electromagnet can be disconnected, causing the attractive force between the annular electromagnet and the annular magnetic plate to disappear, thus ceasing the oiling operation. This allows for timely oiling and effective control of the oiling operation, facilitating oiling and improving oiling efficiency. Furthermore, the movement of the pressure plate and the movement of the eccentric seat are linked to drive the oiling operation, effectively reducing equipment costs.

[0030] 2. The servo motor, small pulley, belt, and large pulley enable the rotating shaft and two eccentric sleeves to rotate synchronously. This causes the mounting frame, eccentric seat, connecting seat, top cover, and rubber pad to move up and down in a cyclical motion, which can cause standing fitness personnel to shake and exercise. The elastic buffer column will cushion the movement of the mounting frame and other components, effectively reducing the probability of noise, protecting the fitness environment, and ensuring the comfort of fitness personnel.

[0031] 3. Using a piston, lubricating oil inside the straight cylinder flows along the hose, the first annular tube, the connecting tube, and the second annular tube. It then passes through multiple first, second, and third nozzles to lubricate the connection points between the bearing housing and the rotating shaft, the eccentric sleeve and the eccentric seat, and the mounting post and the eccentric seat. This ensures normal bearing movement, effectively reduces friction, and extends bearing life. It also reduces noise and allows for simultaneous lubrication of multiple bearings used for rotating connections within the upper cover. The structure is simple and cost-effective.

Detailed Implementation

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] Example 1:

[0044] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a rhythmic device, including a lower cover 3 and an upper cover 2 movably installed on the upper end of the lower cover 3, and four support seats 31 are respectively installed at the four corner positions of the lower end of the lower cover 3. The four support seats 31 are used in cooperation to support the lower cover 3 and make the lower cover 3 stable.

[0045] A groove 21 is formed by recessing the upper end of the cover 2 downwards. The groove 21 provides installation space for the rubber pad 1. The rubber pad 1, whose upper end face overlaps with the upper end face of the cover 2, is installed on the groove 21. Multiple protrusions 11 that are integral with the rubber pad 1 are evenly arranged on the upper end of the rubber pad 1. The rubber pad 1 provides a standing support.

[0046] When in use, the structure formed by the upper cover 2 and the lower cover 3 is first placed in the predetermined position, and the four support seats 31 are in contact with the ground. The four support seats 31 can support the lower cover 3, so that the structure is placed stably and has high stability.

[0047] Then, the person exercising stands on the top of the rubber mat 1, and the top cover 2 is driven to move up and down in a circular motion, which causes the rubber mat 1 to move up and down in a circular motion, making the person exercising shake and thus enabling them to perform exercise. This structure is simple, easy to carry, and convenient to use.

[0048] Furthermore, the multiple protrusions 11 evenly installed on the rubber pad 1 increase the coefficient of friction, enabling the exerciser to stand stably, and also massage the soles of the feet of the standing exerciser, providing good comfort.

[0049] Example 2:

[0050] When using a standing shaking assembly consisting of a placement structure and a standing structure for fitness activities, a drive device is generally used to shake the standing structure. During the shaking process, relative motion occurs between the standing structure and the placement structure. This motion can generate noise, which can affect the fitness environment, disturb the standing fitness user, and make them feel uncomfortable.

[0051] To solve the above problems, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, two bearing seats 4 are symmetrically fixed at the bottom inside the lower cover 3. The two bearing seats 4 are symmetrically rotated and connected to the outer end of the rotating shaft 7 located in the middle of the lower cover 3 and arranged in a horizontal direction through the bearings. The two bearing seats 4 work together to make the rotating shaft 7 and the lower cover 3 rotatably connected.

[0052] The large pulley 6, located between the two bearing seats 4 and directly in front of the small pulley 62, is mounted on the outer end of the rotating shaft 7. The fixed part of the drive device, located behind the rotating shaft 7 and between the two bearing seats 4, is installed on the bottom inside of the lower cover 3. The small pulley 62, which is connected to the large pulley 6 via the belt 61, is then connected to the movable part of the drive device. The small pulley 62 is driven to rotate by the drive device, which can be a servo motor 63.

[0053] The controller 33, located on the lower side of the large pulley 6 and between the two bearing seats 4, and electrically connected to the annular electromagnet 372 and the drive device respectively, is installed on the bottom of the inside of the lower cover 3. The controller 33 controls the switch and rotation speed of the drive device. The controller 33 is connected to a mobile APP via Bluetooth for easy operation. The structure and working principle of the controller 33 are existing public technologies and will not be described in detail.

[0054] Two speakers 101, located on the outside of the connecting seat 43 and electrically connected to the controller 33 and the power supply, are symmetrically installed on the bottom inside of the lower cover 3. Music is played through the speakers 101 to assist in fitness activities. The power supply 32, located in front of the controller 33 and in front of the bearing seat 4 and electrically connected to the annular electromagnet 372, the drive device, and the controller 33, is set on the bottom inside of the lower cover 3. The power supply 32 provides power to the annular electromagnet 372, the drive device, and the controller 33. The structure and working principle of the speakers 101 and the power supply 32 are existing public technologies and will not be described in detail.

[0055] Two eccentric sleeves 53 are respectively set on the left and right ends of the rotating shaft 7, and the eccentric seat 5, which has a gourd-shaped cross section, is located inside the lower cover 3 and extends into the upper cover 2, is rotatably connected to the outer end of the eccentric sleeve 53 through the bearing. The eccentric seat 5 moves up and down in a cyclic motion through the eccentric sleeve 53.

[0056] The eccentric seat 5 is rotatably connected to the outer end of the mounting post 58 located on the upper side of the eccentric sleeve 53 via a bearing, and two connecting seats 43 fixed inside the top of the upper cover 2 are respectively set to the left and right ends of the mounting post 58. The two connecting seats 43 cooperate with the mounting post 58 to connect the eccentric seat 5 to the upper cover 2.

[0057] Four cylinders 34, which are integral with the lower cover 3, are respectively set at the four corners of the bottom inside the lower cover 3. The cylinders 34 provide a mounting carrier for the elastic buffer column 41, and the vertically arranged elastic buffer column 41 is set at the upper end of the cylinder 34. The buffering operation is achieved through the elastic buffer column 41.

[0058] The mounting bracket 42 located outside the eccentric seat 5 is set on the upper end of the elastic buffer column 41, and two mounting brackets 42 are symmetrically installed on the lower end of the assembly formed by the two connecting seats 43. The elastic buffer column 41 is connected to the connecting seat 43 through the mounting brackets 42.

[0059] When in use, the fitness person first stands on the upper end of the rubber mat 1, and then connects the circuit between the drive device and the power supply 32 through the controller 33 and starts the drive device, thereby driving the small pulley 62 to rotate, and under the transmission of the belt 61, the large pulley 6 rotates, which in turn causes the rotating shaft 7 to rotate, thereby causing the two eccentric sleeves 53 to rotate synchronously.

[0060] During the rotation of the eccentric sleeve 53, the eccentric seat 5 will vibrate up and down in a circular motion, which in turn will cause the connecting seat 43 to move up and down in a circular motion, thereby causing the upper cover 2 and the rubber pad 1 to move up and down in a circular motion. This can cause the standing fitness person to vibrate, which can promote the blood circulation of the fitness person and enable the fitness person to perform fitness exercises.

[0061] During the up-and-down cyclic movement of the connecting seat 43, the mounting frame 42 will also move up and down cyclically. When the mounting frame 42 moves upward, it will pull the elastic buffer column 41. When the mounting frame 42 moves downward, it will press down the elastic buffer column 41. The elastic buffer column 41 will buffer the movement of the mounting frame 42 and other components, effectively reducing the probability of noise, effectively protecting the fitness environment, and ensuring the comfort of fitness personnel.

[0062] Example 3:

[0063] like Figure 4 , Figure 6 and Figure 8 As shown, two boxes 35, which are located on the outside of the bearing housing 4 and on the inside of the cylinder 34 and are used to store lubricating oil, are symmetrically installed on the bottom inside of the lower cover 3. Two straight cylinders 37, which are symmetrically arranged inside the lower cover 3 and outside the bearing housing 4, are respectively installed on the upper end of the boxes 35. The boxes 35 provide a mounting carrier for the straight cylinders 37. A suction tube 374 with a one-way valve and the other end connected to the boxes 35 is connected and installed on the lower end of the straight cylinders 37. The straight cylinders 37 and the boxes 35 are connected through the suction tubes 374.

[0064] An annular limiting plate 373 located below the piston 363 is installed on the inner wall of the straight cylinder 37. The annular limiting plate 373 restricts the downward movement of the piston 363. The other end of a hose 38, which is connected to the straight cylinder 37 and located below the annular limiting plate 373 and has a one-way valve and is connected to the outer end of the first annular tube 51, is connected to the straight cylinder 37. Lubricating oil is delivered outward through the hose 38.

[0065] The piston 363 is slidably connected to the straight cylinder 37, and the round rod 361, which extends out of the upper side of the straight cylinder 37 and is arranged vertically, is installed on the middle of the upper end of the piston 363. Then, the pressure plate 36, which is attached to the lower end of the eccentric seat 5, is set on the upper end of the round rod 361. The pressure plate 36 and the round rod 361 work together to make the piston 363 move down along the straight cylinder 37.

[0066] The vertical part of the T-shaped plug 371, which is slidably connected to the outer end of the round rod 361 and whose horizontal part is attached to the upper end of the straight cylinder 37, is threaded into the straight cylinder 37. The T-shaped plug 371 seals the opening of the straight cylinder 37 to protect the internal components of the straight cylinder 37, and provides an installation carrier for the annular electromagnet 372.

[0067] An annular electromagnet 372, located outside the round rod 361, is installed on the lower end of the T-shaped plug 371. An annular magnetic plate 362, located outside the round rod 361 and attached to the lower end of the annular electromagnet 372, is placed on the upper end of the piston 363. The annular electromagnet 372 and the annular magnetic plate 362 are arranged to attract each other. When the annular electromagnet 372 and the annular magnetic plate 362 work together, the piston 363 will move upward and return to its original position.

[0068] When oiling is needed, first turn on the circuit of the annular electromagnet 372, which will cause the annular electromagnet 372 and the annular magnetic plate 362 to attract each other. Under the action of the attraction force, the annular magnetic plate 362 will move upward, which will cause the piston 363 to move upward along the straight cylinder 37, which will cause the cylinder and the pressure plate 36 to move upward, and make the pressure plate 36 contact the lower end of the eccentric seat 5.

[0069] During the up-and-down cyclical movement of the eccentric seat 5, the downward movement of the eccentric seat 5 will cause the pressure plate 36 to move down, which in turn will cause the round rod 361, the annular magnetic plate 362 and the piston 363 to move down, which can create a distance between the annular magnetic plate 362 and the annular electromagnet 372, and squeeze the lubricating oil in the straight cylinder 37 and located on the lower side of the piston 363 into the lubricating oil for the oiling movement.

[0070] When the eccentric seat 5 moves upward, the magnetic plate 362, piston 363, cylinder and pressure plate 362 will move upward and return to their original positions due to the attraction force generated between the annular electromagnet 372 and the annular magnetic plate 362. The pressure plate 36 returns to its original position to facilitate subsequent oiling.

[0071] Furthermore, the upward movement of piston 363 will generate negative pressure in the straight cylinder 37. Under the action of negative pressure, the lubricating oil in the box 35 will enter the straight cylinder 37 along the suction pipe 374, thereby replenishing the lubricating oil into the straight cylinder 37 and enabling continuous oiling operations.

[0072] When oiling is not required, disconnect the circuit of the annular electromagnet 372, so that the attraction between the annular electromagnet 372 and the annular magnetic plate 362 disappears, so that the pressure plate 36 cannot always contact the eccentric seat 5, and thus the piston 363 does not move up and down in the straight cylinder 37, thereby stopping the oiling operation.

[0073] It enables timely oiling and effectively controls the oiling operation, facilitating oiling and improving oiling efficiency. Furthermore, it links the movement of the pressure plate 36 with the movement of the eccentric seat 5 to drive the oiling operation, effectively reducing equipment costs.

[0074] Example 4:

[0075] When using a standing shaking structure for fitness exercises, there are multiple rotating connection points within the structure, and these connections are generally achieved using bearings. To ensure that the bearings can move for extended periods, each bearing needs to be lubricated periodically. However, using a mechanical structure to drive the lubrication requires installing a mechanical structure at each bearing location, which complicates the structure and increases the cost of lubrication.

[0076] To solve the above problems, such as Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the first annular tube 51, located outside the eccentric sleeve 53 and below the connecting seat 43, is installed on the inner end of the eccentric seat 5. Multiple second nozzles 54, arranged in a circular pattern and facing the connection position between the eccentric sleeve 53 and the eccentric seat 5, and arranged at an angle, are equidistantly connected to the inner end of the first annular tube 51. The multiple second nozzles 54 work together to apply oil to the connection position between the eccentric sleeve 53 and the eccentric seat 5.

[0077] Multiple first nozzles 52, arranged in a circular pattern and facing the connection between the bearing housing 4 and the rotating shaft 7, are equidistantly connected and installed on the inner end of the first annular pipe 51. The multiple first nozzles 52 work together to apply oil to the connection between the bearing housing 4 and the rotating shaft 7.

[0078] A second annular pipe 56, located outside the mounting post 58 and above the first annular pipe 51, is placed on the inner end of the eccentric seat 5. Multiple third nozzles 57, arranged in a circular pattern and facing the connection position between the mounting post 58 and the eccentric seat 5, are equidistantly connected to the inner end of the second annular pipe 56. The multiple third nozzles 57 work together to apply oil to the connection position between the mounting post 58 and the eccentric seat 5.

[0079] The upper end of the first annular pipe 51 and the lower end of the second annular pipe 56 are connected by the connecting pipe 55.

[0080] During the downward movement of piston 363, the lubricating oil in straight cylinder 37 is squeezed into hose 38, and the lubricating oil in hose 38 flows along first annular pipe 51, connecting pipe 55 and second annular pipe 56. Then, through multiple first spray pipes 52, the lubricating oil flowing in first annular pipe 51 is sprayed to the connection position between bearing seat 4 and rotating shaft 7, thereby lubricating the connection position between bearing seat 4 and rotating shaft 7.

[0081] The lubricating oil flowing in the first annular pipe 51 is sprayed through multiple second nozzles 54 to the connection position between the eccentric sleeve 53 and the eccentric seat 5, thereby applying oil to the connection position between the eccentric sleeve 53 and the eccentric seat 5. The lubricating oil flowing in the second annular pipe 56 is sprayed through multiple third nozzles 57 to the connection position between the mounting post 58 and the eccentric seat 5, thereby applying oil to the connection position between the mounting post 58 and the eccentric seat 5.

[0082] On the one hand, it ensures that the bearing can move normally, effectively reduces friction and extends the service life of the bearing. On the other hand, it can reduce noise and achieve synchronous oiling of multiple bearings used for rotational connection inside the upper cover 2. The structure is simple and the cost is low.

[0083] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
