[0066] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0067] Example 1: A treadmill controller, used to control the operation of the treadmill's drive motor, such as... Figure 1 As shown, it includes:

[0068] The signal detection circuit 110 is used to detect the motor signal of the drive motor, the motor signal including speed signal, voltage signal and current signal; the control circuit is coupled to the signal detection circuit 110 and the drive motor, the control circuit is used to control the drive motor to work according to the motor signal;

[0069] The control circuit 120 is used to control the drive motor to start automatically, stop automatically, and adjust its speed automatically based on the operating status of the drive motor and the motor signal.

[0070] In this embodiment, the signal detection circuit 110 periodically samples the speed, voltage, and current of the drive motor, and sends the sampled speed signal, voltage signal, and current signal to the control circuit 120. Based on the operating status of the drive motor and the received motor signals, the control circuit 120 controls the drive motor to start automatically, stop automatically, and adjust its speed automatically.

[0071] Automatic speed adjustment:

[0072] S110. In the state where the drive motor is started, the control circuit 120 performs speed adjustment judgment based on the speed signal, the voltage signal and the current signal respectively, and obtains a judgment result corresponding to each signal.

[0073] The judgment result is acceleration, deceleration, or constant speed;

[0074] In this embodiment, the speed signal, voltage signal, and current signal are respectively used as target signals. The work of the control circuit 120 in making corresponding speed adjustment judgments based on the target signals includes:

[0075] The target signal is analyzed to obtain the periodic variation trend and peak variation trend corresponding to the target signal;

[0076] When the periodic change trend is decreasing and the peak change trend is increasing, an acceleration judgment is generated;

[0077] When the periodic change trend is increasing and the peak change trend is decreasing, a deceleration judgment is generated.

[0078] The following section uses a current signal as the target signal as an example to provide a detailed explanation of the specific scheme for speed regulation judgment:

[0079] The running speed of the runner at time a is Sa, and the waveform of the current signal is Figure 2 shown as follows:

[0080] Through digital signal processing and mathematical analysis on the collected current signals, the peak value Pa and period Ta are obtained;

[0081] At time b, the peak value Pb and period Tb are calculated based on the current signal corresponding to the current time;

[0082] When Pb>Pa and Tb<Ta, an acceleration judgment is generated;

[0083] When Pb<Pa and Tb>Ta, a deceleration judgment is generated;

[0084] In other cases, the speed of the running belt remains unchanged, that is, a constant speed judgment is generated.

[0085] S120, after obtaining the judgment results corresponding to each signal, the control circuit 120 further performs majority ruling based on the judgment results to obtain a corresponding speed regulation result.

[0086] In this embodiment, the control circuit 120 counts and compares the quantities of various current judgment results, and takes the judgment result with a larger quantity as the speed regulation result. If the quantities of various judgment results are the same, the speed remains unchanged.

[0087] Note:

[0088] A person skilled in the art can process the signal by means of digital filtering, FFT mathematical transformation (Fast Fourier Transform), statistical analysis and other means according to actual conditions to obtain corresponding digital values of period and peak value, which is not specifically limited in this specification;

[0089] A person skilled in the art can add digital quantities such as average value and frequency according to actual conditions, and supplement the conditions for speed regulation judgment based on these digital quantities;

[0090] A person skilled in the art can set the interval period or time window for statistical judgment results according to actual requirements, which is not specifically limited in this specification.

[0091] S130, the control circuit 120 performs linear speed regulation on the driving motor based on the speed regulation result.

[0092] That is, based on the speed regulation result, the speed is gradually increased or decreased according to a preset unit quantity, so as to realize linear speed regulation.

[0093] In this embodiment, the controller 100 is designed so that during use, the control circuit 120 analyzes the voltage, current and speed of the motor in real time through the signal detection circuit 110, and automatically adjusts the speed according to the user's needs, providing the user with the required speed in a very close and real-time manner, which greatly increases the running comfort.

[0094] Automatic startup:

[0095] When the drive motor is not started, if the control circuit 120 detects that the speed of the drive motor has reached the start threshold based on the speed signal and continues for a preset time, the control circuit 120 controls the drive motor to start.

[0096] In this embodiment, when the control circuit 120 detects that the speed of the drive motor has reached the start-up threshold and continues for a preset duration based on the speed signal, and then further detects that the speed is 0, the control circuit 120 controls the drive motor to start based on the preset initial speed.

[0097] In practical applications, when the drive motor is not running, the runner can push the running belt with their feet (either forward or backward). The running belt drives the drive motor to rotate. The speed of the drive motor reaches the preset start-up threshold (e.g., greater than 100 RPM) and continues for a certain period of time (e.g., 3 seconds). After stopping pushing the running belt, the treadmill enters the start-up state and starts running at the preset initial speed, thus completing the treadmill start-up.

[0098] For treadmills without handrails, they can only be started by remote control or buttons. If a detection element (photoelectric sensor or pressure sensor) is set on the treadmill, it will start automatically when someone is detected on the treadmill. On the one hand, there is the possibility of false alarms, and on the other hand, the sudden start poses a safety hazard.

[0099] Based on the controller 100 provided in this embodiment, when the treadmill needs to be used, the user only needs to push the running belt forward or backward with their foot. When the control circuit 120 recognizes that the starting conditions are met through the signal detection circuit 110, it controls the drive motor to start. Starting is convenient and does not require the assistance of additional devices. Since the user only pushes the running belt with one foot on the ground and starts the drive motor only after stopping pushing, it effectively prevents accidental starting and is safer.

[0100] Automatic stop:

[0101] When the drive motor is in the start state, after the control circuit 120 detects that the speed signal, the voltage signal and / or the current signal are in a stable state for a preset time, the control circuit 120 controls the drive motor to stop.

[0102] When a treadmill is running, the runner's movement (or walking) on ​​the running belt causes fluctuations in the motor speed, motor current, and motor voltage (e.g., ...). Figure 3 As shown), when the user leaves the treadmill (gets off the running belt), the motor's speed, voltage, and current will enter a relatively stable state (as shown). Figure 4 As shown, the control circuit 120 detects that each signal is in a stable state for a preset time through the signal detection circuit 110, and then determines that the runner has left the treadmill, thereby stopping the drive motor.

[0103] In this embodiment, the controller 100 can automatically stop the drive motor when the user leaves the treadmill, making it convenient to use.

[0104] Example 2: A treadmill control box, comprising a box body 11 and a box cover 12, as shown below. Figure 5 As shown:

[0105] The box body 11 has an inner cavity, in which a controller 100 is provided. The controller 100 is the treadmill controller 100 described in Embodiment 1.

[0106] The box body 11 and / or the box cover 12 are provided with a connector 13, which is used to detachably connect to the treadmill body 20.

[0107] In this embodiment, the connector 13 is a snap fastener, and the connector 13 is disposed on the cover 12. In actual use, the cover 12 is fixed to the box body 11, and the cover 12 is fixed to the treadmill body 20 through the connector 13, thereby fixing the entire control box 10 to the treadmill body 20.

[0108] The important functional components of modern treadmills are scattered across the machine body, which not only increases the complexity of the machine structure but also increases the potential for failure and installation difficulty. When a component is damaged, after-sales service and repair are particularly difficult. One solution is to take the entire treadmill to the after-sales service center or back to the factory for repair, which is troublesome and has high transportation costs. Another solution is for after-sales service personnel to come to the site for repair, which is difficult and costly.

[0109] As can be seen from the description of Embodiment 1, by designing the controller 100, it is possible to achieve automatic start, automatic speed adjustment and automatic stop of the treadmill without setting any vulnerable detection elements on the treadmill body 20.

[0110] For the electronic control unit that is prone to failure, the current practice is to set up a corresponding inspection port on the treadmill for easy maintenance by staff. However, this solution requires staff to come to the site, which is labor-intensive and inefficient. In this embodiment, there is no need to use the detection elements distributed on the treadmill body 20, and the controller 100 that is prone to failure is integrated into the control box 10. The entire control box 10 can be separated from the treadmill body 20. When maintenance or replacement is required, the user only needs to take out the entire control box 10 and can complete the maintenance or replacement by mail.

[0111] Reference Figure 5 The box cover 12 is provided with a display screen 14, which is coupled to the controller 100. The control circuit 120 of the controller 100 can generate a corresponding running speed based on the rotation speed signal detected by the signal detection circuit 110 and feed it back to the user through the display screen 14.

[0112] Furthermore, the housing 11 is also provided with a connector, which is coupled to the controller 100, and the controller 100 controls the drive motor to work through the connector.

[0113] The drive motor is located inside the treadmill body 20. In this embodiment, the design of the plug-in component further reduces the barrier for users to disassemble and install the control box 10.

[0114] Reference Figure 5 The control box 10 also includes a power switch 16 and a power connection cable 15;

[0115] The controller 100, display screen 14 and drive motor are coupled to the mains power through the power connection line 15. In practical applications, the mains power supplies the entire treadmill through the power connection line 15.

[0116] The power switch 16 is used to control the power on or off of the controller 100 and the display screen 14.

[0117] Example 3: A treadmill, such as Figure 6 The diagram shows a treadmill body 20 and a control box 10, wherein the control box 10 is the control box 10 described in Embodiment 2;

[0118] The treadmill body 20 includes a mounting cavity 21 and a drive motor 22, and the controller 100 of the control box 10 is coupled to the drive motor 22.

[0119] like Figure 7 As shown, a fixing seat 211 is provided on the mounting cavity 21, and the connector 13 of the control box 10 works in cooperation with the fixing seat 211 to detachably fix the control box 10 to the mounting cavity 21.

[0120] In this embodiment, the mounting cavity 21 is a concave cavity, the connector 13 adopts a snap fastener, and the fixing seat 211 is a snap fastener seat corresponding to the snap fastener. In actual use, the control box 10 is embedded in the mounting cavity 21 and fixed to the mounting cavity 21 by the snap fastener and the snap fastener seat.

[0121] This embodiment integrates all vulnerable electrical control components of the treadmill into the control box 10 for easy maintenance and replacement. The design of the mounting cavity 21, connector 13, and fixing base 211 ensures convenient assembly and disassembly and reliable connection.

[0122] Reference Figure 8 Furthermore:

[0123] The mounting cavity 21 is provided with a plug-in socket 212, which is coupled to the drive motor 22;

[0124] The controller 100 of the control box 10 is coupled to the drive motor 22 through the plug-in 212.

[0125] In practical applications, users only need to place the control box 10 into the mounting cavity 21 to complete the connection between the controller 100 and the drive motor 22, making disassembly and installation easy.

[0126] Reference Figure 8 ;

[0127] To ensure safe use, the mounting cavity 21 is provided with a lead-out hole 213 that matches the power connection cable 15 of the control box 10. During installation and use, the power connection cable 15 is led out from the lead-out hole 213 and connected to the mains power.

[0128] Reference Figure 8 :

[0129] In this embodiment, the treadmill body 20 also includes a base 23, a cover plate 24, a transmission mechanism 25, a front roller 26, a rear roller, and a running belt 28;

[0130] The drive motor 22 is installed at the front of the base 23 (the front is in front of the user when running). In this case, the drive motor is a brushless motor. The front roller 26 and the rear roller are installed on the front and rear sides of the base 23 respectively. The running belt 28 is installed on the front roller 26 and the rear roller. The drive motor 22 drives the front roller 26 and the rear roller to rotate through the transmission mechanism 25, thereby causing the front roller 26 and the rear roller to drive the running belt 28 to rotate. When the drive motor 22 stops, the user pushes the running belt 28, and the running belt 28 will drive the front roller 26 and the rear roller to rotate, thereby causing the transmission mechanism 25 to drive the motor shaft of the drive motor 22 to rotate, so that the controller 100 can detect the speed of the drive motor 22.

[0131] The cover plate 24 is fixed to the front of the base 23, and the cover plate 24 is recessed to form an inner cavity, namely, the mounting cavity 21.

[0132] In this embodiment, in order to facilitate the adjustment of the base 23, the bottom of the base 23 is provided with adjusting feet 27 for adjusting the height and parallelism of the base 23.

[0133] In summary, in this embodiment, the treadmill body 20 and the control box 10 are two independent parts that together constitute the treadmill. They can be produced and tested separately during the production stage to optimize the production process and improve production efficiency. During transportation, the control box 10 can be shipped separately as a consumable part to reduce the failure rate caused by transportation. When maintenance is required, the user only needs to remove the control box 10 for replacement. The control box 10 is small in size, lightweight, and easy to disassemble, assemble, and transport.
