The present disclosure involves the field of intelligent fitness and specifically, involves an intelligent fitness device and method for updating a position of the intelligent fitness device.
The working principle of the intelligent fitness device: the intelligent fitness device includes a motor, a differential, a support arm, a pull rope, a controller, a circuit, and an accessory. A spool is connected between a motor output shaft and the differential. One end of the pull rope is connected with the differential, and the other end of the pull rope is connected with a pull ring or other fitness accessories. A user may exercise by pulling the pull rope or using the support arm. When the motor is powered on, it may generate an output torque, that is, a resistance. A user needs to overcome the output torque of the motor when pulling the pull rope and the output torque is controlled by controlling the motor, so as to achieve the purpose of strength training.
The above fitness device may be used to carry out a variety of strength training to help the user complete strength training of different types and intensities, but in the actual use process of the above fitness device, due to the resistance between the motor output shaft and the spool as well as the existence of the differential, a deviation of the pull-out distance of the spool in actual operation may occur, resulting in a shaking of the spool, which brings certain safety hazards to the training.
To improve a stability and safety of the above intelligent fitness device, the present disclosure provides a method for updating a position of an intelligent fitness device.
To achieve the above purpose, the present disclosure provides a method for updating a position of an intelligent fitness device, which is applied to the intelligent fitness device, the intelligent fitness device including a motor, a first spool, and a second spool, wherein the method comprises the following operations:
The principle of the present disclosure is that: when a user uses the intelligent fitness device, to calculate the pull-out distances of the motor and the first spool, the first initial position data of the motor, the second initial position data of the first spool, the first real-time position data of the motor, and the second real-time position data of the first spool need to be obtained. When obtaining the first initial position data and the second initial position data, it is necessary to determine whether a floating range of the first initial position data and the second initial position data at adjacent moments exceeds a preset range, in response to the determination that the floating range exceeds the preset range, it means that the motor and the first spool are floating. At this time, the first initial position data and the second initial position data needs to be reset, and then based on the obtained initial position data and real-time position data, the first pull-out distance of the motor and the second pull-out distance of the first spool may be calculated. Since the moving speed or the real-time position data of the motor and the first spool may affect the pull-out distance of the motor and the first spool, the first pull-out distance needs to be corrected and updated to obtain the third pull-out distance, and the second pull-out distance needs to be corrected and updated to obtain the fourth pull-out distance. Finally, the pull-out distance of the second spool may be accurately calculated based on the third pull-out distance and the fourth pull-out distance. Thereby, a shaking of the spool during operation can be reduced, and the stability and safety of the intelligent fitness device can be improved.
Preferably, in the method, the first pull-out distance of the motor and the second pull-out distance of the first spool are calculated by the following formulas:
the first pull-out distance=the first real-time position data−the first initial position data, and
the second pull-out distance=the second real-time position data−the second initial position data.
Where, a difference between the real-time position data and the initial position data of the motor is the pull-out distance of the motor, and a difference between the real-time position data and the initial position data of the first spool is the pull-out distance of the first spool. Through the above formulas, the pull-out distances of the first spool and the motor can be accurately calculated.
Preferably, in the method, determining whether the first real-time position data is greater than the first initial position data; in response to the determination that the first real-time position data is greater than the first initial position data, calculating the first pull-out distance; or in response to the determination that the first real-time position data is not greater than the first initial position data, determining the first pull-out distance as zero; and determining whether the second real-time position data is greater than the second initial position data; in response to the determination that the second real-time position data is greater than the second initial position data, calculating the second pull-out distance; or in response to that the second real-time position data is not greater than the second initial position data, determining the second pull-out distance as zero.
The set of the above condition is for explain that the values of the pull-out distances of the first spool and the motor are always non-negative numbers.
Preferably, in the method, the updating the first pull-out distance of the motor and the second pull-out distance of the first spool specifically includes:
The average value of the moving distance of the motor and the first spool within a preset time, or the real-time position data of the motor and the first spool may both affect the pull-out distances of the motor and the first spool. The correction and the updating may be performed on the pull-out distances of the motor and the first spool based on the above determination conditions.
Preferably, in the method, the determining whether the first real-time position data of the motor and the second real-time position data of the first spool satisfy preset conditions specifically includes the following two conditions:
The above conditions are set to determine whether the real-time positions of the motor and the first spool are floating, if at adjacent moments, a difference between the real-time position data of the motor and the first spool is within a preset range and remains longer than the preset time, it means that the real-time position of the motor and the first spool are not floating, and the first initial position data and the second initial position data may be updated.
Preferably, in the method, the pull-out distance of the second spool may be calculated by the following formula:
the pull-out distance of the second spool=the third pull-out distance of the motor−the fourth pull-out distance of the first spool.
Where, the pull-out distance of the second spool is a difference between the third pull-out distance of the motor and the fourth pull-out distance of the first spool.
The present disclosure further provides an intelligent fitness device, including: a motor, a a first spool, a second spool, at least one processor, and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
Preferably, the first pull-out distance of the motor and the second pull-out distance of the first spool are calculated by the following formulas:

the second pull-out distance=the second real-time position data−the second initial position data.

The attached drawings described here are used to provide further understanding of the embodiments of the present disclosure, which constitutes part of the present disclosure, and does not constitute a limit on the embodiments of the present disclosure:
In order to be able to understand the above objects, features, and advantages of the present disclosure more clearly, the present disclosure may be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other under the condition that they do not conflict with each other.
Many specific details are set forth in the following description to facilitate a full understanding of the present disclosure. However, the present disclosure may also be implemented in other ways that are different from the scope of this description. Therefore, the protection scope of the present disclosure is not subject to the limitations of the specific embodiments of the following disclosure.
Please refer to
The first initial position data of the motor and the second initial position data of the first spool may be obtained by a position sensor or an encoder installed on the motor and the first spool. The present disclosure does not limit the way that the motor and the first spool obtain the initial position data.
The first real-time position data and the second real-time position data may be obtained by the number of turns of the motor or the number of turns of the spool. The present disclosure does not limit the way in which the first real-time position data and the second real-time position data are obtained.
Moving speed data of the motor may be obtained from a rotation speed of the motor, and moving speed data of the first spool may be obtained from the rotation speed of the spool. The present disclosure does not limit the way in which the motor and the first spool obtain the moving speed data.
In the embodiments of the present disclosure, controlling the motor in the intelligent fitness device includes: issuing a command to a motor control board through a host computer. The motor control board may be used to control the motor in the intelligent fitness device.
To reset the first initial position data of the motor and the second initial position data of the first spool, that is, to set the motor to zero, the following approaches may be used to perform the zero setting. A DC power supply may be used to apply a DC current less than a rated current to a UV winding of the motor, U phase in, V phase out, and a motor shaft may be oriented to a balanced position. A U-phase signal and a Z zero-position signal of the encoder may be observed with an oscilloscope. A relative position of the encoder's shaft and the motor shaft may be adjusted; meanwhile, a transition edge of the U-phase signal of the encoder and the Z zero-position signal may be observed until the Z zero-position signal is stable at a high level (the default Z zero-position signal is at a low level), and a relative position relation of the encoder and the motor may be locked. The motor shaft may be turned back and forth, and if the Z zero-position signal may be stabilized at a high level every time the motor shaft freely returns to a balanced position, the zero setting is valid. The motor may further use a mechanical zero setting, and the present disclosure does not limit the approaches of zero setting of the motor.
The first pull-out distance of the motor and the second pull-out distance of the first spool may be calculated by the following formulas:
the first pull-out distance=the first real-time position data−the first initial position data;
the second pull-out distance=the second real-time position.
If the first real-time position data is greater than the first initial position data, the first pull-out distance may be calculated, and if the first real-time position data is less than or equal to the first initial position data, the first pull-out distance may be zero (for example, the first real-time position data is 12 and the first initial position data is 2, then the first pull-out distance may be calculated to be 10; for another example, the first real-time position data is 1 and the first initial position data is 3, then the first pull-out distance may be calculated to be 0. The above data is only an explanation of the formula. In practical applications, the data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this). If the second real-time position data is greater than the second initial position data, the second pull-out distance may be calculated, and if the second real-time position data is less than or equal to the second initial position data, the second pull-out distance may be zero (for example, the second real-time position data is 14 and the second initial position data is 2, then the second pull-out distance may be calculated to be 12; for another example, the second real-time position data is 2 and the second initial position data is 4, then the second pull-out distance may be calculated to be 0. The above data is only an explanation of the formula. In practical applications, the data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this).
The first pull-out distance and the second pull-out distance may be updated, the updating process specifically includes: obtaining a first average value of the moving distance of the motor within a preset time, that is, obtaining moving speed data of the motor, which may be obtained through the rotation speed of the motor. If the first average value is less than the first initial position data, the first initial position data may be updated (For example, the preset time is one second, the first average value is 2, the first initial position data is 3, at this time, the first average value is smaller than the first initial position data, then the first initial position data may be updated to 2. In practical applications, the above data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this); obtaining a second average value of the moving distance of the first spool within the preset time, that is, obtaining the speed data of the first spool, the moving speed data of the first spool may be obtained through a rotation speed of the first spool. If the second average value is less than the second initial position data, the second initial position data may be updated (for example, the preset time is one second, the second average value is 4, the second initial position data is 5, at this time, the second average value is smaller than the second initial position data, then the second initial position data may be updated to be 4. In practical applications, the above data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this). Or, at adjacent moments, a difference between the real-time position data of the motor and the first spool is within a preset range and remains longer than the preset time, then updating the first initial position data and the second initial position data (For example, the adjacent time is one second, the preset range is 5, the preset time is 2 minutes, the initial position data of the motor is 2, the real-time position data of the motor is 4, and the initial position data of the first spool is 3, the real-time position data of the first spool is 6, the difference between the real-time position data of the motor in adjacent one second is 2 and it remains for more than 2 min, and the difference between the real-time position data of the first spool in adjacent one second is 3 and it remains for more than 2 min. At this time, the differences between the real-time position data of the motor and the first spool are both smaller than the preset range and remains longer than the preset time, then the real-time position data of the motor may be used as initial position data of the motor, the real-time position data of the first spool may be used as initial position data of the first spool. In practical applications, the above data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this). The first initial position data and the second initial position data may be updated, the initial position data after the update still satisfies the formula: the pull-out distance=the real-time position data−the initial position data, so that the purpose of updating the first pull-out distance and the second pull-out distance may be achieved.
The pull-out distance of the second spool may be calculated through the following formula:
the pull-out distance of the second spool=the third pull-out distance of the motor−the fourth pull-out distance of the first spool.
If the third pull-out distance of the motor has not been updated, the value of the third pull-out distance may be equal to the value of the first pull-out distance; if the fourth pull-out distance of the first spool has not been updated, the value of the fourth pull-out distance may be equal to the value of the second pull-out distance, that is, the pull-out distance of the second spool always satisfies the formula: the pull-out distance of the second spool=the pull-out distance of the motor−the pull-out distance of the first spool. (For example, the third pull-out distance of the motor is 8, and the fourth pull-out distance of the first spool is 3, then the calculated pull-out distance of the second spool is 5. The above data is only to explain the formula, the above data may be flexibly adjusted according to needs, and the present disclosure does not make specific limitations on this).
In this embodiment, the user may perform an impedance motion by pulling the pull rope at the end of the support arm, and the position data of the motor and the first spool may be obtained through the position sensor of the motor and the first spool, and the obtained position data may be fed back to the host computer. The host computer calculates and corrects the obtained position data, and then issues the corresponding command to the motor control board to control the operation of the motor, thereby improving the stability of the spool during operation and ensuring the safety of the user when using the intelligent fitness device. A double sensor may be used to detect the motor position, including an optical encoder and a photoelectric position sensor, the optical encoder is used to detect the position of the first spool, and the photoelectric position sensor is located on the stator, and may detect the motor position, correct, and monitor the optical encoder. In practical applications, the optical encoder and the photoelectric position sensor may be replaced by other sensors with the same or similar functions. The present disclosure does not limit the specific types and models of the above devices. The motor control board may choose a motor starter, an intelligent controller, or a servo controller, preferably a servo controller. The servo controller has the following advantages: a wide speed range, a high positioning accuracy, a sufficient transmission rigidity and a high-speed stability, a quick response, no overshoot, low speed and large torque, strong overload capacity and high reliability.
