TECHNICAL FIELD

[0001] The present application relates to the field of spinning, in particular to a spinning intelligent self-locking system. BACKGROUND

[0002] When the spinning is not used, the industry stipulates that the flywheel must be locked in the state of not rotating for safety considerations. At present, there are two solutions for flywheel self-locking. One is to use an independent lock to lock the flywheel. The other is to use a brake device with a combination of threads and pressing, press for braking, and rotate the threads downward to make the brake pad dead stop the flywheel.

[0003] However, the above-mentioned devices need to manually switch the self-locking state when self-locking, which is relatively troublesome to operate. For example, the solution of using an independent lock to lock the flywheel during non-use of the spinning; the solution of using a brake device with a combination of threads and pressing, press for braking, and rotate the threads downward to make the brake pad dead stop the flywheel, which needs to be rotated for several turns to dead stop the flywheel, and the operation is relatively troublesome.

[0004] Since the above-mentioned solutions need manual state switching, the user may forget to lock the vehicle after exercise, thereby existing a safety hazard. SUMMARY

[0012] In the intelligent self-locking system of the stationary bicycle provided by the application, when the pressure sensor detects that the weight on the stationary bicycle is greater than a threshold value, the controller controls the electromagnet to be powered on, the push rod moves downward, and the brake pad is away from the flywheel.

[0013] In the intelligent self-locking system of the stationary bicycle provided by the application, the electrical control module can further comprise an alarm, and when the middle shaft torsion sensor detects that the torsion value is greater than a self-locking threshold value, the electromagnet fails, and the alarm performs a failure alarm.

[0014] In the intelligent self-locking system of the stationary bicycle provided by the application, the self-locking threshold value can be a minimum value of friction between the brake pad and the flywheel required by an external force driving the flywheel.

The controller is connected with the electromagnet and the sensor assembly. Based on the intelligent self-locking system of the spinning bike, whether there is a user on the spinning bike is detected through the sensor assembly. When the sensor assembly detects that there is a user on the spinning bike, the controller controls the electromagnet to be powered on, so that the push rod moves downward, ensures that the brake pad is away from the flywheel, and the spinning bike is unlocked; when the sensor assembly detects that there is no user on the spinning bike, the controller controls the electromagnet to be powered off, so that the push rod moves upward, ensures that the brake pad is close to the flywheel, and the spinning bike is self-locked.

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0029] The smart self-locking system of the spin bike is applied in a spin bike, and is used to realize self-locking and unlocking of the flywheel 100 of the spin bike.

[0030] As shown in Figures 1-5 , the smart self-locking system of the spin bike comprises a self-locking module 200 and an electrical control module. The electrical control module is connected with the self-locking module.

[0031] The self-locking module comprises a push rod 10, a brake pad 20, a spring 30 and an electromagnet 40. The brake pad 20 is arranged on the push rod 10 close to one end of the flywheel 100 of the spin bike.

[0032] The electromagnet 40 is fixed with the frame of the spin bike and is sleeved on the push rod 10. As shown in Figure 3 , the push rod 10 can make a straight-line extension and retraction movement relative to the electromagnet 40 according to the direction of the arrow A.

[0033] The spring 30 is coaxially arranged with the push rod 10 and is located between the brake pad 20 and the electromagnet 40. When the electromagnet 40 is powered off, the elastic force of the spring 30 can push the brake pad 20 towards the flywheel 100, so that the brake pad 20 contacts the flywheel 100.

[0034] The electrical control module comprises a sensor assembly, a controller, an interactive screen and an alarm. The sensor assembly comprises a pressure sensor and a middle shaft torsion sensor.

[0035] The pressure sensor is arranged at a position on the spin bike which contacts the user, such as a footrest, a seat, a foot pedal, etc. The pressure sensor is used to detect the weight on the spin bike and send the detected data to the controller.

[0036] The middle shaft torque sensor is arranged on the wheel shaft of the driving wheel of the exercise bike, and is used for detecting the torque value on the driving wheel and sending the detected data to the controller.

[0037] The interactive screen is arranged on the frame of the exercise bike, and is used for interacting with the user.

[0038] The controller is connected with the pressure sensor, the middle shaft torque sensor and the electromagnet 40 respectively, can receive the data of the pressure sensor and the middle shaft torque sensor and make a judgment, and can also control the electromagnet 40 to be powered on and powered off.

[0039] The control process of the intelligent self-locking system of the exercise bike is as follows:

[0040] Step 1: the user rides the exercise bike, and turns on the power of the exercise bike through the interactive screen;

[0041] Step 2: after the power is turned on, the pressure sensor detects the weight on the exercise bike, and sends the detected pressure data to the controller, and the controller judges the received pressure data, judges whether the pressure data is greater than the body weight threshold, when the judgment is yes, step 3 is entered; when the judgment is no, step 7 is entered;

[0042] Step 3: the controller controls the electromagnet 40 connected thereto to be powered on, the middle shaft torque sensor detects the torque value and the rotating speed of the driving wheel, and sends the torque value and the rotating speed signal to the controller, and the controller judges the received torque value and the rotating speed, judges that the first rotating speed is not zero, step 4 is entered; judges that the rotating speed is zero and the torque value is greater than the locking threshold, step 5 is entered;

[0043] Step 4: after the electromagnet 40 is powered on, the push rod 10 drives the brake pad 20 to move away from the flywheel 100, and the flywheel 100 is unlocked, and the user starts to ride;

[0044] Step 5: the electromagnet 40 fails to be powered on and an alarm is triggered, and the interactive screen displays that the electromagnet 40 is faulty;

[0045] Step 6: after the user finishes riding, the pressure sensor detects the weight on the exercise bike, and sends the detected pressure data to the controller, and the controller judges the received pressure data, judges whether the pressure data is greater than the body weight threshold, when the judgment is yes, step 3 is entered; when the judgment is no, step 7 is entered;

[0046] Step 7: the controller controls the electromagnet 40 connected thereto to be powered off, and the restoring force of the spring 30 drives the brake pad 20 to move close to the flywheel 100, and the flywheel 100 is locked.

[0047] In the above process, the self-locking threshold is the minimum value of the friction between the brake pad and the flywheel required by the external force to drive the flywheel.

[0048] According to the smart self-locking system of the spin bike in the above-mentioned embodiment, the self-locking module and the electrical control module are connected. The self-locking module includes a push rod, a brake pad, a spring, and an electromagnet; the self-locking module includes a sensor assembly and a controller. The controller is connected with the electromagnet and the sensor assembly. Based on the smart self-locking system of the spin bike, whether there is a user on the spin bike is detected by the sensor assembly. When the sensor assembly detects that there is a user on the spin bike, the controller controls the electromagnet to be powered on, so that the push rod moves downward, ensures that the brake pad is away from the flywheel, and the spin bike is unlocked; when the sensor assembly detects that there is no user on the spin bike, the controller controls the electromagnet to be powered off, so that the push rod moves upward, ensures that the brake pad is close to the flywheel, and the spin bike is self-locked. The smart self-locking system detects whether the spin bike is in a use state through the sensor assembly, then drives the push rod to move through the electromagnet, and thus achieves the unlocking and self-locking of the spin bike, without the need for manual locking and unlocking operation, and the user experience is better. Moreover, the structure of the entire self-locking system is simple and reliable. Furthermore, without manual operation, the situation that a user forgets to lock the bike can be avoided, and thus the safety hazard caused by forgetting to lock the bike is avoided.

[0049] In addition, the brake pad is connected to one end of the push rod and close to the flywheel of the spin bike; the electromagnet is sleeved on the push rod, and the push rod can move linearly relative to the electromagnet to drive the brake pad to move close to or away from the flywheel, thereby achieving the self-locking and unlocking of the spin bike.

[0050] In addition, the spring is coaxially arranged with the push rod and located between the electromagnet and the brake pad. In the flywheel self-locking state, the restoring force of the spring can ensure that the brake pad is always in contact with the flywheel, and has good reliability.

[0051] In addition, the sensor assembly includes a pressure sensor arranged at a position on the spin bike in contact with the user, thereby detecting whether there is a user on the spin bike and whether it is in a use state.

[0052] In addition, the sensor assembly further includes a middle shaft torsion sensor arranged on the wheel shaft of the driving wheel of the spin bike, for detecting the torsion value and the rotation speed of the driving wheel. Whether the flywheel is unlocked can be detected, and when the flywheel is unlocked abnormally, a fault alarm is given through an alarm.

Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and equivalent technologies, the present application also intends to include these modifications and variations.
