Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to a composite fitness device that integrates running exercise with high-frequency vibration stimulation. Background Technology

[0002] Currently, the market mainly offers a type of treadmill that uses brushless motors with high-frequency forward and reverse rotation to achieve vibration (also known as "fat-burning treadmills" or "vibrating treadmills"). The core feature of this type of product is that it controls the brushless motor to switch between forward and reverse rotation at a very short time (usually milliseconds), driving the treadmill pedals or specific contact areas to produce high-frequency reciprocating mechanical displacement, thus simulating a vibration effect. Combined with the aerobic exercise of the running belt and the passive stimulation of the vibration module, it achieves a multi-functional fitness goal, including fat burning and muscle massage.

[0003] However, this technical solution has revealed a series of significant technical flaws in practical applications, severely limiting the user experience, reliability, and functional continuity of the product. For example,

[0004] The heat accumulation effect of the motor is prominent: When the brushless motor works in high-frequency forward and reverse mode, its internal windings need to withstand repeated start-stop current impacts and energy feedback from direction switching. This causes the winding temperature to rise sharply. The continuous high temperature will accelerate the demagnetization of the permanent magnet, reduce the efficiency and service life of the motor, trigger the overheat protection mechanism of the electronic control system, forcibly reduce the motor power or stop the vibration function, so that the vibration effect is significantly attenuated or even interrupted in the critical use stage (such as the middle and late stage of continuous exercise), and cannot maintain effective training intensity.

[0005] Insufficient stability of the electronic control system: High-frequency direction switching requires very precise timing control and strong current driving capability. It is very easy to generate strong back electromotive force during violent commutation, which interferes with the signal acquisition and processing of the control system, resulting in problems such as motor speed fluctuation, commutation step loss (step loss), and program operation disorder (crash, reset). Users directly experience unstable vibration frequency, fluctuating intensity, and unreliable vibration mode.

[0006] Increased equipment noise and poor user comfort: High-frequency forward and reverse rotation and sudden reversal can cause mechanical resonance in the motor itself and connecting parts, generating obvious and sharp electromagnetic noise, which seriously affects the comfort of the user environment.

[0007] Existing treadmills designed for fat burning often produce vibration waveforms with significant impact components, rather than the ideal smooth harmonic vibrations. This can easily cause numbness or muscle discomfort in the user's feet, legs, and even the whole body, resulting in a poor user experience and making prolonged comfortable use impossible. The vibration effect is also poorly coordinated with actual running motion, potentially affecting balance and naturalness during exercise. Energy consumption and efficiency are also issues: frequent starts / stops and changes of direction result in substantial energy loss, leading to low overall energy efficiency and exacerbating heat generation problems.

[0008] Existing multi-functional vibration treadmills mainly rely on the high-frequency forward and reverse rotation scheme of brushless motors. Although this scheme can achieve multiple functions in principle, the high-frequency commutation mode of the motor will cause serious heat accumulation problems, resulting in vibration effect attenuation and safety hazards. Moreover, the high-frequency commutation to switch between running and vibration is complex to control, has poor anti-interference, and leads to poor system stability, uncomfortable vibration waves, and poor physical experience. Utility Model Content

[0009] The technical problem to be solved by this utility model is that the motor operation mode of the existing vibrating treadmill is poorly controlled, resulting in poor vibration effect. In order to overcome the above defects of the existing technology, this utility model provides a composite fitness device that integrates running exercise and high-frequency vibration stimulation.

[0010] This utility model provides a composite fitness device that integrates running exercise and high-frequency vibration stimulation, including a frame, a running belt set in the middle of the frame, a drive motor for driving the running belt to rotate, and a main control board for driving the drive motor to work. The drive motor and the main control board are both fixed to the top of the back of the frame, and the drive motor is electrically connected to the main control board.

[0011] A support frame is fixedly installed in the middle of the back of the frame. A vibration eccentric motor is installed on the support frame. Eccentric blocks are symmetrically connected to the rotating shafts on both sides of the vibration eccentric motor. A control board for driving the vibration eccentric motor is provided next to the main control board. The vibration eccentric motor is electrically connected to the control board, and the control board is electrically connected to the main control board.

[0012] Compared with existing technologies, the composite fitness device integrating running exercise and high-frequency vibration stimulation proposed in this application has the following advantages: the main control board independently controls the drive motor to drive the running belt, and the control board independently controls the vibration eccentric motor. The dual drive and dual system control, and the separate setting of the drive motor and vibration eccentric motor facilitates heat dissipation. This allows users to receive passive high-frequency mechanical vibration while actively running or walking, improving energy consumption efficiency per unit time (fat burning effect), and promoting muscle activation and relaxation, thus meeting users' needs for improved fitness efficiency and multi-functional integration.

[0013] In one possible implementation, the eccentric block includes a shaft support and an eccentric portion, the center of which is connected to the shaft of the vibrating eccentric motor, and the eccentric portion is connected to the radial sidewall of the shaft support.

[0014] Compared with existing technologies, the eccentric structure is achieved by connecting the rotating shaft support to the vibration eccentric motor and then connecting the eccentric part, resulting in simpler components and easier manufacturing.

[0015] In one possible implementation, the longitudinal section of the shaft support is circular, and the longitudinal section of the eccentric part is fan-shaped.

[0016] Compared with existing technologies, the circular shaft support is more convenient to connect with the shaft of the vibration eccentric motor; the fan-shaped eccentric part is easy to connect with the shaft support.

[0017] In one possible implementation, the radial length of the outer edge of the eccentric portion is less than the radius of the vibrating eccentric motor.

[0018] Compared with existing technologies, this technology prevents the eccentric block from becoming excessively eccentric, which could lead to excessive vibration when the eccentric motor is working.

[0019] In one possible implementation, the top of the drive motor is provided with a first protective cover, which is fixed to the frame; the top of the vibrating eccentric motor is provided with a second protective cover, which is fixed to the support frame.

[0020] Compared with existing technologies, the drive motor is protected by a first protective cover, and the vibrating eccentric motor is protected by a second protective cover.

[0021] In one possible implementation, the vibrating eccentric motor is fixedly connected to a mounting plate, which is secured to a support frame by a plurality of bolts and studs.

[0022] Compared with existing technologies, fixing the vibration eccentric motor by using a mounting plate, and then using bolts and studs to fix it to the support frame, is simpler and more convenient.

[0023] In one possible implementation, the bottom of the frame is equipped with a plurality of support feet.

[0024] Compared with existing technologies, the method of providing support for the frame by setting support feet is more practical and has a longer service life.

[0025] In one possible implementation, rollers are mounted on the top of both sides of the back of the frame.

[0026] Compared to existing technologies, the addition of rollers makes it easier to move the entire device.

[0027] In one possible implementation, both the drive motor and the vibration eccentric motor are DC brushed motors or DC brushless motors. Attached Figure Description

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0038] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] See Figures 1-6 As shown in the figure, this application discloses a composite fitness device that integrates running exercise and high-frequency vibration stimulation, including a frame 1, a running belt 2 disposed in the middle of the frame 1, a drive motor 3 for driving the running belt 2 to rotate, and a main control board for driving the drive motor 3 to work. The drive motor 3 and the main control board are both fixed to the top of the back of the frame 1, and the drive motor 3 is electrically connected to the main control board.

[0041] The frame 1, running belt 2, drive motor 3, and main control board constitute the existing treadmill, on which users can run. A rotating rod is pressed into one side of the running belt 2, and a wheel is mounted on the side of the rotating rod. The shaft of the drive motor 3 is connected to the wheel via a belt, so that when the drive motor 3 rotates, it drives the belt to rotate, which in turn drives the wheel to rotate, which in turn drives the rotating rod to rotate, and finally the rotating rod drives the running belt 2 to rotate. This entire process is existing technology and will not be described in detail here.

[0042] In this embodiment, a support frame 4 is fixedly provided in the middle of the back of the frame 1. A vibration eccentric motor 5 is provided on the support frame 4. Eccentric blocks 6 are symmetrically connected to the rotating shafts on both sides of the vibration eccentric motor 5. A control board for driving the vibration eccentric motor 5 is provided next to the main control board. The vibration eccentric motor 5 is electrically connected to the control board, and the control board is electrically connected to the main control board.

[0043] The main control board independently controls the drive motor 3 to drive the running belt, and the control board independently controls the vibration eccentric motor 5. The dual drive and dual system control enable users to receive passive high-frequency mechanical vibration while actively running or walking, improving energy consumption efficiency per unit time (fat burning effect), and promoting muscle activation and relaxation. This meets users' needs for improved fitness efficiency and multi-functional integration, achieving a stable, efficient, and comfortable vibration effect.

[0044] Specifically, different modes are achieved by controlling the main control board and the control board, for example:

[0045] Pure running mode: Only the main control board drives motor 3 to work;

[0046] Fat-burning mode: Only the control board drives the vibration eccentric motor 5 to work, and the vibration eccentric motor 5 operates in the high-frequency range;

[0047] Running mode: The main control board drives the drive motor 3 to work, so that the speed of the running belt 2 is ≤6km / h. At the same time, the control board drives the vibration eccentric motor 5 to work, and the vibration frequency is synchronously matched and can be set by the user.

[0048] Relaxation mode: After running stops, the control board starts the vibration eccentric motor 5, and the vibration eccentric motor 5 operates in the low frequency range.

[0049] The main control board and the control board can be fabricated as separate circuit boards and then electrically connected to each other via pins and wires to achieve data transmission. This facilitates disassembly, and if one of them is damaged, it can be directly replaced. Alternatively, the main control board and the control board can be integrated onto a single circuit board, which simplifies overall fabrication and installation.

[0050] The vibration generated by the eccentric motor 5 during operation is transmitted to the support frame 4, and then to the frame 1, achieving overall vibration. In this embodiment, both the drive motor 3 and the eccentric motor 5 are DC brushed motors. Of course, in actual use, both the drive motor 3 and the eccentric motor 5 can be DC brushless motors.

[0051] In the actual design process, the drive motor 3 and the main control board are both located at the top of the back of the frame 1. Therefore, there is space in the middle and bottom of the back of the frame 1, which can be used to place the support frame 4 and the vibration eccentric motor 5 in the space in the middle of the back of the frame 1, physically isolated from the drive motor 3, and also facilitate heat dissipation for the two motors.

[0052] Furthermore, the internal space of the running belt 2 can be expanded, and the support frame 4 and the vibration eccentric motor 5 can be placed inside the running belt 2. Then, the vibration generated by the vibration eccentric motor 5 when it works is transmitted to the support frame 4, and the support frame 4 transmits it to the frame 1 to achieve overall vibration.

[0053] In this embodiment, see Figure 5 and Figure 6 As shown, the eccentric block 6 includes a shaft support part 61 and an eccentric part 62. The center of the shaft support part 61 is connected to the shaft of the vibration eccentric motor 5, and the eccentric part 62 is connected to the radial sidewall of the shaft support part 61.

[0054] The eccentric motor 5 is connected to the rotating shaft support 61, and the overall eccentric structure is achieved by connecting the eccentric part 62. The components are simple and easy to manufacture.

[0055] The longitudinal section of the shaft support 61 is circular, and the longitudinal section of the eccentric part 62 is fan-shaped. The circular shaft support 61 makes it easier to connect to the shaft of the vibrating eccentric motor 5; the fan-shaped eccentric part 62 is easier to connect to the shaft support 61.

[0056] Considering the limited space in the middle of the back of the actual frame 1, the radial length of the outer edge of the eccentric part 62 is less than the radius of the vibration eccentric motor 5. This is to prevent the eccentric block 6 from being excessively eccentric, which would cause excessive vibration when the vibration eccentric motor 5 is working.

[0057] The entire eccentric block 6, through this design, makes the vibration eccentric motor 5 work more stably, improves durability, extends its lifespan, and reduces noise over long-term use. Its volume is just similar to the diameter of the vibration eccentric motor 5, making reasonable use of space.

[0058] Of course, if there is enough space in the middle of the back of the frame 1, the radial length of the outer edge of the eccentric part 62 can be designed to be greater than or equal to the radius of the vibration eccentric motor 5.

[0059] In this embodiment, see Figure 2 As shown, the top of the drive motor 3 is provided with a first protective cover 31, which is fixed to the frame 1; the top of the vibration eccentric motor 5 is provided with a second protective cover 51, which is fixed to the support frame 4.

[0060] The drive motor 3 is protected by the first protective cover 31, and the vibration eccentric motor 5 is protected by the second protective cover 51.

[0061] In this embodiment, see Figure 4 As shown, the vibration eccentric motor 5 is fixedly connected to a mounting plate 52, which is fixed to the support frame 4 by multiple bolts and studs 53.

[0062] The vibration eccentric motor 5 is fixed by mounting plate 52, and then fixed to the bearing frame 4 by bolts and studs 53, which makes the fixing simpler and more convenient.

[0063] The bottom of the rack 1 is equipped with multiple support feet 7. The support feet 7 provide support for the rack, which is practical and has a long service life. For example, a support foot 7 is set at each of the four corners of the bottom of the rack 1, and a support foot 7 is also set on each of the two middle sides of the bottom of the rack 1.

[0064] The top of both sides of the back of the frame 1 are equipped with casters 8. The casters 8 facilitate the movement of the entire device.

[0065] This embodiment has the following advantages over the prior art:

[0066] 1. The thermal failure problem has been completely eliminated, resulting in a breakthrough improvement in system stability.

[0067] Continuous operating time: Under full-load vibration mode, the continuous stable working time is ≥60 minutes, which is a significant improvement over the traditional brushless motor solution (severe overheating after 15 minutes).

[0068] Failure rate control: By eliminating the high-frequency commutation operation, the error rate of the electronic control system is reduced to a minimum, the heat generation of the electronic control system is reduced accordingly, the overall failure rate of the machine is significantly reduced, maintenance costs are reduced, and returns and repairs are reduced.

[0069] Benefits include: uninterrupted user training and usage, improved equipment utilization, and enhanced user experience.

[0070] 2. Energy consumption and material costs have both decreased, demonstrating significant advantages in green energy saving.

[0071] Power consumption optimization: By using a brushed motor, the peak power of the vibration module is reduced.

[0072] Simplified structure: The brushless motor's dedicated heat sink and high-current drive IC (such as IR2184S) are eliminated, reducing the number of electronic components and lowering the BOM cost.

[0073] 3. Revolutionary upgrade in ergonomic design, resulting in a leap forward in comfort experience.

[0074] Noise control: The support foot pad 7 adopts a multi-layer silicone-metal conductive structure, which attenuates high-frequency resonant energy by 92%. Then, when the entire fitness equipment is placed on the yoga mat, the working noise is ≤45dB(A), reaching the quiet level of a library.

[0075] Vibration waveform optimization: The ERM motor, in conjunction with the damping layer, outputs a sinusoidal wave with low acceleration harmonic distortion, improving the uniformity of foot pressure distribution for users.

[0076] Benefits: Feedback indicates "no tingling or numbness," and extended comfortable training duration.

[0077] 4. Create breakthrough multifunctional value.

[0078] A dynamic collaborative algorithm is set in the main control board and control board to achieve precise matching of motion and vibration: in walking and running mode, the vibration frequency can be turned on simultaneously (e.g., 5km / h→8Hz) to improve fat oxidation efficiency; after running, the relaxation mode (low frequency vibration) is automatically switched to, which accelerates the blood lactate clearance rate.
