For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] The arm strength device of this embodiment includes a motor, a main control unit, a first arm 1, a second arm 2, etc. Figures 1 to 3 shown.

[0046] The electric machine comprises a stator and a rotor.

[0047] One end of the first lever arm 1 is connected to the stator; the positions of the first lever arm 1 and the stator are relatively fixed.

[0048] One end of the second force arm 2 is connected to the rotor; when the rotor rotates, the second force arm is driven to rotate.

[0049] The main control unit controls the operation of the motor. The main control unit can control the direction and magnitude of the motor current, etc.

[0050] The motor is used as the resistance source of the arm trainer. When the rotor of the motor rotates, the rotor drives the second lever arm 2 to rotate, that is, resistance is generated between the two lever arms. The user applies force to the first lever arm and the second lever arm to achieve the purpose of training by overcoming the resistance between the two lever arms.

[0051] The arm trainer of this embodiment is designed with a motor as a resistance source, one end of the first force arm is connected to the stator of the motor, one end of the second force arm is connected to the rotor of the motor, and the main control unit controls the operation of the motor; when the rotor of the motor rotates, the rotor drives the second force arm to rotate, that is, resistance is generated between the two force arms, and the user achieves the purpose of training by overcoming the resistance; the arm trainer of this embodiment uses a motor instead of a spring as a resistance source, and the exercise function can be achieved without designing a spring, and the motor will not deform, and the stability is better than that of a spring, and the safety is strong, thereby improving the safety and stability, and solving the technical problems of poor safety and poor stability of the arm trainer in the prior art.

[0052] The main control unit and motor are the core control parts of the arm trainer, which control all functions of the arm trainer.

[0053] The main control unit drives the motor through the drive unit (MOS tube or IPM) to control the motor output torque and torque direction. The main control unit (such as a single-chip microcomputer) controls the MOS tube or IPM to output a controllable current to the motor. Different supply currents and different rotor speeds can cause the motor to output different torques.

[0054] In some embodiments of the present application, in order to improve the flexibility of use of the arm trainer, the arm trainer also includes an operating unit for adjusting the direction and size of the motor current; the operating unit is electrically connected to the main control unit.

[0055] The user operates the operating unit, the operating unit receives the user's operating signal, and transmits the received operating signal to the main control unit, and the main control unit controls the motor current direction and current size according to the received operating signal.

[0056] The user can adjust the current size and direction of the motor through the operating unit. By setting different current values, the user can generate corresponding resistance between the two arms of the arm trainer, and achieve the purpose of training by overcoming the resistance.

[0057] When the current supplied to the motor changes, the speed of the rotor changes, and the resistance between the first and second lever arms changes, which can meet the different strength requirements of users. The motor current is continuously adjustable, so the resistance between the two lever arms is continuously adjustable to meet a variety of strength requirements. In addition, the rebound speed of the two lever arms is adjustable, which improves the safety of the arm strength device.

[0058] When the direction of the current supplied to the motor changes, the rotation direction of the rotor changes, and the direction of the resistance between the first force arm and the second force arm changes. Therefore, the direction of force can be changed by changing the direction of the current. The resistance direction of the two force arms can be achieved both inward and outward. Users can achieve both inward squeezing training and outward stretching training, which improves the flexibility of using the arm trainer.

[0059] In some embodiments of the present application, in order to facilitate user operation, the operating unit includes a control button and an adjustment knob, and the control button and the adjustment knob are electrically connected to the main control unit respectively.

[0060] The control button is used to change the direction of the motor current. The control button is electrically connected to the main control unit and sends an operation signal to the main control unit. The main control unit controls the direction of the motor current according to the received operation signal.

[0061] The adjusting knob is used to adjust the motor current. The adjusting knob is electrically connected to the main control unit and sends an operation signal to the main control unit. The main control unit controls the motor current according to the received operation signal.

[0062] The control button and the adjustment knob may also be integrated into one knob, which can change the direction of the current (the direction of the resistance) and adjust the magnitude of the current (the magnitude of the resistance).

[0063] In some embodiments of the present application, in order to facilitate users to obtain various operating parameters of the arm exerciser, the arm exerciser also includes a display screen. The main control unit is electrically connected to the display screen. The main control unit controls the operation of the display screen and controls the display screen to display the current direction and size of the motor.

[0064] In some embodiments of the present application, in order to facilitate user operation, the display screen can be a touch screen. An operating unit for adjusting the direction and magnitude of the motor current is integrated on the touch screen, and the touch screen collects the user's touch operation and sends the collected operation signal to the main control unit. The main control unit controls the direction and magnitude of the motor current according to the received operation signal. At the same time, the touch screen displays the current direction and magnitude of the motor current.

[0065] In some embodiments of the present application, in order to facilitate the acquisition of the rotation angle of the rotor and enrich the functions of the arm trainer, the arm trainer further includes an angle sensor, which is electrically connected to the main control unit. The angle sensor detects the rotation angle of the rotor and sends the detected signal to the main control unit. The main control unit controls the display screen to display the rotation angle of the rotor for easy observation by the user.

[0066] In some embodiments of the present application, the other end of the first lever 1 is sleeved with a first handle 3 to facilitate user gripping, and a first pressure sensor is disposed in the first handle 3 to detect the magnitude of the force applied to the first handle 3. The first pressure sensor sends the detected pressure signal to the main control unit. The main control unit controls the display screen to display the pressure signal for user observation.

[0067] The other end of the second lever arm 2 is sleeved with a second handle 4 for the convenience of the user to hold. A second pressure sensor is arranged in the second handle 4 for detecting the magnitude of the force applied to the second handle 4. The second pressure sensor sends the detected pressure signal to the main control unit. The main control unit controls the display screen to display the pressure signal for the convenience of the user to observe.

[0068] The two handles are the parts that the user contacts with the equipment, and the training purpose is achieved by squeezing the hands inward or stretching them outward.

[0069] In some embodiments of the present application, in order to facilitate the arm trainer to communicate with other devices and facilitate the user to control the operation of the arm trainer, the arm trainer also includes a Bluetooth module, and the Bluetooth module is electrically connected to the main control unit. The main control unit communicates with the mobile terminal through the Bluetooth module.

[0070] The user can conveniently obtain various parameters of the arm trainer and various exercise data of the user through the mobile terminal, and the user can also control the arm trainer through the mobile terminal.

[0071] For example, the main control unit transmits the current motor current direction, current magnitude, rotor rotation angle, user applied pressure, etc. to the mobile terminal through the Bluetooth module, and the user can obtain the operating parameters and motion data of the arm exerciser through the mobile terminal. The user can also change the operation of the arm exerciser, such as the motor current direction and magnitude, through the mobile terminal.

[0072] The Bluetooth module can communicate with other Bluetooth devices, making it convenient to upload the arm exerciser data and for other Bluetooth devices to control the arm exerciser.

[0073] The arm trainer of this embodiment can achieve the purpose of power monitoring or remote control by designing a Bluetooth module. Other Bluetooth devices (such as mobile phones) can share the user's exercise data (such as the opening and closing range of both hands, the number of opening and closing, etc.) in real time.

[0074] In some embodiments of the present application, in order to protect the main control unit and the motor, the arm trainer also includes a disc-shaped shell 5, and the main control unit and the motor are located inside the shell 5.

[0075] A first strip hole and a second strip hole are arranged at intervals along the circumferential direction of the shell on the circumferential surface of the shell.

[0076] One end of the first force arm extends into the first strip hole and is connected to the stator of the motor.

[0077] One end of the second force arm extends into the second strip hole and is connected to the rotor of the motor. When the rotor rotates, the second force arm rotates along the length direction of the second strip hole. The second strip hole plays a role of limiting and guiding.

[0078] In some embodiments of the present application, in order to facilitate the use of electricity by various electrical components in the arm exerciser, the arm exerciser further includes a battery, which supplies power to various electrical components of the arm exerciser. The battery is installed in the housing.

[0079] In some embodiments of the present application, in order to facilitate user use, avoid frequent battery replacement, and reduce costs, the battery is a rechargeable battery, and the arm trainer also includes a charging interface, which is used to charge the battery. The external power source charges the battery through the charging interface.

[0080] The arm trainer of this embodiment uses a motor as a source of resistance. The motor is more operable and monitorable than ordinary mechanical products. The Bluetooth module is used to share exercise data, and a more complete exercise system can be formed by interacting with other Bluetooth devices.

[0081] The arm trainer of this embodiment uses a small motor instead of a spring as a resistance source. Due to the controllability of the motor torque and the monitorability of the position, it is equipped with a transmission Bluetooth module and has the following advantages:

[0082] (1) The motor current is continuously adjustable, so the resistance between the two force arms is continuously adjustable. One arm strength device can meet the strength requirements of different users and has good versatility.

[0083] (2) The direction of force can be changed by changing the direction of current, and the direction of resistance can be inward or outward.

[0084] (3) No spring, no hydraulic pressure, and the handle rebound speed is adjustable, which is highly safe.

[0085] (4) No deformation occurs and the stability is better than that of a spring.

[0086] (5) When used with a Bluetooth module, it can be used for power monitoring or remote control purposes.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
