[0002] As a fitness tool, the vibration burner is designed to help users exercise and shape their bodies through vibration. Currently, most vibration burners on the market use physical buttons or remote controls to adjust the vibration speed to suit different users' fitness needs. However, this design has some obvious shortcomings: 1. Inconvenient operation: The physical buttons on traditional fat-burning machines are often located on the surface of the machine. When users are standing on the fat-burning machine, they need to bend over or move their bodies to operate it. This not only increases the inconvenience for users, but may also affect the exercise effect or cause safety hazards.

[0003] 2. Signal interference: The signal of a fat-burning machine that uses a remote control to adjust the speed is easily affected by external electromagnetic interference, especially in places such as gyms. The simultaneous use of multiple devices may cause signal conflicts, leading to malfunctions.

[0004] 3. High failure rate: Physical buttons and remote controls are prone to malfunction or damage after prolonged use, requiring regular replacement or repair, which increases user costs and inconvenience.

[0005] 4. Cost issues: While the addition of physical buttons and a remote control provides convenience for speed adjustment, it also increases production costs and affects the product's cost-effectiveness.

[0006] Therefore, it is necessary to develop a new control circuit for a smart fat-burning machine without buttons or a remote control, as well as a smart fat-burning machine. Utility Model Content

[0007] The purpose of this invention is to provide a control circuit and an intelligent fat-burning machine without buttons and remote control, so as to solve the problems of inconvenient operation and signal interference of traditional fat-burning machines.

[0008] In the first aspect, the control circuit of the intelligent fat-burning machine without buttons and remote control described in this utility model includes a microprocessor, a current detection and processing unit, and a motor drive unit. The current detection and processing unit includes a current sampling circuit, a current amplification circuit, and a low-pass filter circuit. The current sampling circuit is connected in series in the motor drive circuit to sample the motor current in real time. The current amplification circuit is connected to the current sampling circuit and amplifies the sampled motor current before outputting it to the microprocessor for peak current acquisition. The low-pass filter circuit is connected to the output terminal of the current amplifier circuit and is used to filter out high-frequency noise and output an average current to the microprocessor. The microprocessor determines the change in the user's standing position based on the peak current and average current and outputs a corresponding PWM signal. The motor drive unit adjusts the motor's operating speed based on PWM signals.

This design greatly improves user convenience, allowing users to focus more on the exercise itself, while avoiding potential safety hazards caused by inconvenient operation.

[0016] (2) Remote control-free design eliminates signal interference: Because this fat-burning machine adopts a remote-free design, relying entirely on the microprocessor's analysis of the motor current to adjust the speed, there is no problem with the signal being affected by external electromagnetic interference. Whether in a home environment or a gym where multiple devices are used simultaneously, it ensures stable and accurate operation.

[0017] (3) Reduce physical components and improve reliability: Traditional fat-burning machines often suffer from high failure rates due to their physical buttons and remote controls.

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0022] like Figure 1 As shown in the embodiment of this application, a control circuit for a buttonless and remote-controlled smart fat-burning machine includes a microprocessor 5, a current detection and processing unit, and a motor drive unit 1. The current detection and processing unit includes a current sampling circuit 2, a current amplification circuit 3, and a low-pass filter circuit 4. The current sampling circuit 2 is connected in series in the motor drive circuit for real-time sampling of the motor current. The current amplification circuit 3 is connected to the current sampling circuit 2 and amplifies the sampled motor current before outputting it to the microprocessor 5 for peak current acquisition. The low-pass filter circuit 4 is connected to the output of the current amplification circuit 3 to filter out high-frequency noise and output the average current to the microprocessor 5. The microprocessor 5 determines the change in the user's standing position based on the peak current and average current and outputs a corresponding PWM signal. The motor drive unit 1 adjusts the operating speed of the motor 7 based on the PWM signal.

[0023] The microprocessor 5 does not use any additional physical sensors, but relies entirely on real-time sampling of the motor current to detect the user's operating intentions. This embodiment abandons traditional remote controls such as buttons, infrared, and Bluetooth, directly using the current changes of the motor 7 during operation as the basis for detecting user intentions, reducing the complexity and cost of hardware components. The change in motor current is directly related to the load of the vibrating machine. By accurately measuring the current, the user's standing position can be indirectly determined, enabling intelligent control of the speed of the motor 7. This avoids the signal interference and misreading problems that may exist with remote controls, improving the stability and reliability of the intelligent vibrating machine.

[0024] like Figure 1 As shown, in one possible embodiment, the current sampling circuit 2 includes a sampling resistor R1, one end of which is connected to the motor drive unit 1, and the other end of which is grounded.

[0025] like Figure 1 As shown, in one possible embodiment, the current amplification circuit 3 includes an operational amplifier U1, resistors R2, R3, and R4. The non-inverting input of the operational amplifier U1 is connected to the sampling resistor R1 via resistor R2, and the inverting input of the operational amplifier U1 is grounded via resistor R4. The inverting input of the operational amplifier U1 is also connected to the output of the operational amplifier U1 via resistor R3. The output of the operational amplifier U1 is connected to the peak current acquisition terminal of the microprocessor 5, and the output of the operational amplifier U1 is also connected to the low-pass filter circuit 4.

[0026] like Figure 1 As shown, in one possible embodiment, the low-pass filter circuit 4 includes a resistor R5 and a capacitor C1. One end of the resistor R5 is connected to the output terminal of the current amplifier circuit 3, and the other end of the resistor R5 is connected to one end of the capacitor C1 and the average current acquisition terminal of the microprocessor 5. The other end of the capacitor C1 is grounded. The low-pass filter circuit 4, composed of resistor R5 and capacitor C1, effectively removes high-frequency noise from the motor current signal and improves signal quality.

[0027] like Figure 1 As shown, in one possible embodiment, the motor drive unit 1 includes a power transistor Q1. The drain of the power transistor Q1 is connected to the motor 7, the source of the power transistor Q1 is connected to the current sampling circuit 2, and the gate of the power transistor Q1 is connected to the microprocessor 5. The power transistor Q1 controls the operating speed of the motor 7 through a PWM signal. The power transistor Q1 can quickly respond to the control signals of the microprocessor 5, ensuring real-time adjustment of the motor speed.

[0028] like Figure 2 As shown in the embodiment of this application, a smart fat-burning machine without buttons and a remote control includes a fat-burning machine body 6, a motor 7, and a control circuit 8. The control circuit 8 is connected to the motor 7. The fat-burning machine body 6 includes a fat-burning machine plate 9 and a transmission mechanism (not shown in the figure), etc., dividing the fat-burning machine plate 9 into an acceleration zone 10, a deceleration zone 12, and a fat-burning zone 11. The control circuit 8 adopts the smart fat-burning machine control circuit without buttons and a remote control as described in the embodiment of this application.

[0029] like Figure 3 As shown in this embodiment, by dividing the vibrating machine plate 9 into different areas and using the change in the user's standing position as the input signal, the use of traditional buttons or remote controls is cleverly avoided, simplifying the user interface. The microprocessor 5 analyzes the changing trend of the motor current to identify the user's standing position, and then adjusts the duty cycle of the PWM signal to control the speed of the motor 7. This design not only improves the user experience but also significantly reduces the equipment's failure rate and production costs.

[0030] In one possible embodiment, the fat-burning machine plate 9 is provided with a deceleration zone 12, a fat-burning zone 11, and an acceleration zone 10 sequentially from the middle to the end. The layout of the deceleration zone 12, fat-burning zone 11, and acceleration zone 10 sequentially from the middle to the end in the design of the fat-burning machine plate 9 provides the microprocessor 5 with a clearer basis for zone division. When the user stands in different zones, the current signal of the motor 7 will exhibit different characteristics, and the microprocessor 5 determines the user's position based on these characteristics.

[0031] For example, when a user stands in deceleration zone 12, the pressure distribution of their body weight on the fat-burning machine plate 9 changes, causing a decrease in the load on motor 7. At this time, the current signal of motor 7 may show a downward trend or remain within a relatively stable low value range. By detecting this change in the motor current signal, microprocessor 5 can determine that the user is standing in deceleration zone 12 and issue a deceleration command accordingly. Fat-burning zone 11 is the main area for the user to perform fat-burning exercises. When the user stands in fat-burning zone 11, the load on motor 7 will remain in a relatively stable state to maintain the constant speed of the fat-burning machine. At this time, the motor current signal may show a relatively stable value or fluctuate within a small range. By recognizing this stable motor current signal characteristic, microprocessor 5 can determine that the user is exercising in fat-burning zone 11 and maintain the current speed. When the user moves from the fat-burning zone 11 to the acceleration zone 10, the load on the motor 7 increases. This is because the acceleration zone 10 is located at the end of the fat-burning machine, and when the user stands in the acceleration zone 10, it will exert greater pressure on the fat-burning machine plate 9. At this time, the motor current signal will show an upward trend. By detecting this change in the motor current signal, the microprocessor 5 can determine that the user is standing in the acceleration zone 10 and issue an acceleration command accordingly.

[0032] The operation of this intelligent fat-burning machine begins with power-on. At this time, the microprocessor 5 automatically initializes the motor speed and drives the motor 7 to start running by controlling the PWM output. The user adjusts the speed of the machine by changing their standing position. When the user stands with their feet apart in the acceleration zone 10, the motor current increases. The microprocessor 5 detects this change and automatically increases the duty cycle of the PWM signal, accelerating the motor 7. Once the motor 7 accelerates to the user's desired speed, the user simply moves their feet to the fat-burning zone 11, and the motor 7 maintains the current speed stably. If the user wishes to slow down, they simply stand with their feet together in the deceleration zone 12. At this time, the motor current decreases, and the intelligent fat-burning machine automatically reduces the duty cycle of the PWM signal, slowing the motor 7 down. Throughout the entire process, the user does not need to touch any physical buttons or use a remote control; the entire speed adjustment process is fully intelligent, greatly enhancing the user experience. When the user leaves the machine, the microprocessor 5 detects a sudden drop in motor current and automatically executes a deceleration program until the preset minimum operating speed is reached to ensure safety.

[0033] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
