Description

Technical Field

[0001] This invention relates to the field of fitness equipment, and in particular to a control method for a treadmill. Background Technology

[0002] Treadmills are a common type of indoor fitness equipment. They use a motor to drive a running belt, allowing users to run or walk. However, existing treadmills are relatively limited in function, only allowing running and walking (i.e., the treadmill's controller sets the running belt to rotate at different speeds), which restricts their use.

[0003] In view of the above problems, it is necessary to study a control method for treadmills to solve the problem of the limited functionality of existing treadmills. Summary of the Invention

[0004] The purpose of this invention is to provide a control method for a treadmill, thereby solving the problem of limited functionality in existing treadmills.

[0005] To achieve the above objectives, the solution of the present invention is: A control method for a treadmill, the treadmill having a running belt, a drive motor for driving the running belt to rotate, and a controller for controlling the drive motor, the control method comprising the following steps: Step 1: The controller obtains the user's input function mode command; Step 2: The controller executes the corresponding function mode according to the function mode instruction. The function modes include running mode, back walking mode, shaking mode, balance mode and resistance mode. The running mode is as follows: the controller controls the drive motor to drive the running belt to rotate forward at the set forward speed; The reverse mode is as follows: the controller controls the drive motor to drive the running belt to reverse at a set reverse speed; The vibration mode is as follows: the controller controls the drive motor to drive the running belt to reciprocate forward and reverse at a set vibration cycle time; where the vibration cycle time is the total time of one forward rotation and one reverse rotation of the running belt in the vibration mode; The balancing mode is as follows: the controller controls the drive motor to drive the running belt to reciprocate forward and reverse at a set balancing cycle time; wherein, the balancing cycle time is the total time of one forward rotation and one reverse rotation of the running belt in the balancing mode, and this balancing cycle time is greater than the jitter cycle time. The resistance mode is as follows: the controller controls the drive motor to generate a counter torque.

[0006] The controller uses an MCU processor.

[0007] The drive motor has an encoder.

[0008] The drive motor is a servo motor.

[0009] The vibration cycle time is 100±5 milliseconds; within one vibration cycle, the ratio of the time for the running belt to rotate forward and the time for the running belt to rotate backward is 1:1.

[0010] The balancing cycle time is 500~1000 milliseconds; within one balancing cycle, the ratio of the time for the running belt to rotate forward and the time for the running belt to rotate in reverse is 1:1, the speed of the drive motor when the running belt rotates forward is 240~480 RPM, and the speed of the drive motor when the running belt rotates in reverse is 240~480 RPM.

[0011] By adopting the above solution, the present invention enables the treadmill to perform multiple controls on the drive motor through the controller, thereby realizing running mode, backward walking mode, shaking mode, balance mode and resistance mode, which greatly enriches the functions of the treadmill, meets the diverse usage needs of users, and improves the practicality of the treadmill.

[0013] Figure 2 This is a hardware principle block diagram of the present invention. Detailed Implementation

[0014] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0015] like Figure 1 and Figure 2 As shown, this invention discloses a control method for a treadmill, the treadmill having a running belt 3, a drive motor 2 for driving the running belt 3, and a controller 1 for controlling the drive motor 2; the control method for the treadmill of this invention includes the following steps: Step 1: Controller 1 obtains the user's input function mode command; Step 2: Controller 1 executes the corresponding function mode according to the function mode instruction. The function modes include running mode, back walking mode, shaking mode, balance mode and resistance mode.

[0016] In an embodiment of the present invention, the running mode is as follows: the controller 1 controls the drive motor 2 to drive the running belt 3 to rotate forward at a set forward speed. In running mode, the user can perform running and walking exercises.

[0017] In an embodiment of the present invention, the backward walking mode is as follows: the controller 1 controls the drive motor 2 to drive the running belt 3 to reverse at a set reverse speed. In the backward walking mode, the user can perform backward walking exercise.

[0018] In an embodiment of the present invention, the shaking mode is as follows: the controller 1 controls the drive motor 2 to drive the running belt 3 to reciprocate forward and reverse rotations at a set shaking cycle time; wherein, the shaking cycle time is the total time of one forward rotation and one reverse rotation of the running belt 3 in the shaking mode, and the shaking cycle time can be 100±5 milliseconds; within one shaking cycle time, the ratio of the time for forward rotation to the time for reverse rotation of the running belt 3 is 1:1. In the shaking mode, the user stands on the running belt 3 and moves back and forth rapidly with the running belt 3, thereby causing the user's muscles to shake, so as to relax the user's muscles.

[0019] In an embodiment of the present invention, the balancing mode is as follows: the controller 1 controls the drive motor 2 to drive the running belt 3 to reciprocate forward and reverse rotations at a set balancing cycle time; wherein, the balancing cycle time is the total time of one forward rotation and one reverse rotation of the running belt 3 in the balancing mode, and this balancing cycle time is greater than the shaking cycle time, and the balancing cycle time can be 500~1000 milliseconds; within one balancing cycle time, the ratio of the time for forward rotation to the time for reverse rotation of the running belt is 1:1, the speed of the drive motor during forward rotation is 240~480 RPM, and the speed of the drive motor during reverse rotation is 240~480 RPM. In the balancing mode, the user stands on the running belt 3 and engages their core muscles to maintain body balance, thereby achieving core muscle training.

[0020] In an embodiment of the present invention, the resistance mode is as follows: the controller 1 controls the drive motor 2 to generate a counter-torque. In resistance mode, the user pushes off the running belt 3 to counteract the counter-torque generated by the drive motor 2, thereby performing resistance training. Specifically, the controller 1 adjusts the counter-torque generated by the drive motor 2 by adjusting the drive current of the drive motor 2; furthermore, the controller 1 can control the drive motor 2 to generate a counter-torque only after the user applies force to the running belt 3 (specifically, the controller 1 first keeps the drive motor 2 stationary; when the user applies force to the running belt 3, the running belt 3 drives the drive motor 3 to rotate; at this time, the controller 1 determines that the user has applied force to the running belt 3 through the encoder or the back electromotive force generated by the drive motor 3, and only then does the controller 1 control the drive motor 2 to generate a counter-torque). It should be noted that this resistance mode is not an essential functional mode of the present invention.

[0021] In an embodiment of the present invention, the controller 1 is an MCU processor, the drive motor 2 is a servo motor, and the drive motor 2 has an encoder. The present invention can accurately detect the speed and rotation position of the drive motor 2 through the encoder, and cooperate with the controller 1 to realize precise closed-loop control of the rotation state of the running belt 3, ensuring the operating accuracy of the running belt 3 in each functional mode, and improving the stability and safety of user use.

[0022] As can be seen from the above, the present invention uses controller 1 to perform various controls on drive motor 2, enabling the treadmill of the present invention to realize running mode, backward walking mode, shaking mode, balance mode and resistance mode, which greatly enriches the functions of the treadmill, meets the diverse usage needs of users, and improves the practicality of the treadmill.

[0023] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
