This is a U.S. National Stage under 35 U.S.C. 371 of the International Application Number PCT/CN2022/104295, filed July 7, 2022, which claims priority under 35 U.S.C. 119 to China patent application entitled “Brake Device and Brake Driver of Sports Apparatus”, filed Jul. 8, 2021, application number 202011097162.3, the content of which is incorporated herein by reference in their entirety.
The present invention relates to a sport apparatus, in particular to a sport apparatus and a brake device thereof, a brake driver and an integrated external magnetic control module.
A sport apparatus such as spinning bicycles are common indoor fitness apparatus, which are usually configured with a flywheel. By driving the flywheel to rotate, the flywheel is allowed to provide inertial force as a load to achieve the load adjustment function. Specifically, for the spinning bicycle, its flywheel and foot pedal member are interrelated in motion. Users can drive the flywheel to rotate by pedaling the foot pedal member, and the rotational speed of the flywheel is related to the frequency of the foot pedal member being pedaled. The higher the frequency of the foot pedal member being pedaled, the faster the rotational speed of the flywheel, and the greater the inertial force that the flywheel can provide at this time. Conversely, the lower the frequency of the foot pedal member being pedaled, the slower the rotational speed of the flywheel, and the smaller the inertial force that the flywheel can provide at this time. Typically, the weight of the flywheel is large, so once the flywheel is driven and in a rotating state, it tends to provide a large inertial force. In this case, even if the foot pedal member is not pedaled further, the inertial force of the flywheel will drive the foot pedal member to rotate, which may cause injuries to the user (in particular to the user's feet or legs). Therefore, the spinning bicycle is often provided with a brake device to achieve rapid braking of the flywheel. In addition, in recent years, the magnetic control resistance device has been applied to the sport apparatus such as the spinning bicycle, which cooperates with the flywheel, so as to achieve the adjustment of the resistance force by adjusting the distance between the permanent magnet of the magnetic control resistance device and the aluminum disc of the flywheel. The brake device and the magnetic control resistance device of the sport apparatus such as existing spinning bicycle are arranged independently at the corresponding positions of the flywheel, resulting in the complex structure, low reliability, and high cost of the sport apparatus such as the spinning bicycle.

When the lower end portionof the brake driverdrives the braking endof the braking mechanismto move towards the rim edgeof the flywheel, the tension springaccumulates the elastic potential energy due to the elastic deformation. Correspondingly, when the lower end portionof the brake driverdoes not drive the braking endof the braking mechanism, the tension springdrives the braking endof the braking mechanismto move in the direction away from the rim edgeof the flywheelduring the process of restoring the initial state, so that a gap is defined between the braking endof the braking mechanismand the rim edgeof the flywheel.
Continuing with reference to, the brake drivercomprises a driving rodand an encoding unitdisposed at an upper end of the driving rod, wherein the upper end of the driving rodforms the upper end portionof the brake driver, correspondingly, the lower end of the driving rodforms the lower end portionof the brake driver, and the driving rodis capable of passing through the operating channelof the magnetic control housingand the through grooveof the magnetic control armof the external magnetic control assemblysequentially, so as to be capable of driving the braking endof the braking mechanismto move towards the rim edgeof the flywheelsubsequently. Preferably, the driving rodis rigid, for example, the driving rodcan be but not limited to a metal rod, so that when the upper end of the driving rodis pressed, the lower end of the driving rodis capable of transmitting the pressure force to the braking endof the braking mechanismdirectly, so as to allow the pivoting endof the braking mechanismto rotate relative to the magnetic control resistance deviceand to allow the braking endof the braking mechanismto move towards the rim edgeof the flywheel to brake the flywheelquickly. Therefore, the brake devicehas higher braking efficiency and is convenient for users to use.
Referring to, the apparatus framehas an moving channel, a middle portion of the driving rodis disposed at the moving channelof the apparatus framemovably, and the moving channelof the apparatus frameguides the moving direction of the driving rod. When the user drives the driving rodto move along the track formed by the moving channelof the apparatus framein the manner of pressing the upper end of the driving rod, the lower end of the driving rodis capable of being abutted on the extending bodyof the braking mechanism, so as to drive the braking endof the braking mechanismto move towards the rim edgeof the flywheel, and when the braking padof the braking mechanismcontacts the rim edgeof the flywheel, the friction force is generated between the braking padof the braking mechanismand the rim edgeof the flywheelto brake the flywheelquickly.
Preferably, continuing with reference to, the brake devicefurther comprises a resetting device, and the resetting deviceis configured to be connected with the driving rodand the apparatus frame, wherein after the external force applied to the upper end of the driving rodis removed, the resetting devicedrives the driving rodto move along the track formed by the moving channelof the apparatus frameto restore the initial state. More preferably, the resetting deviceis a compression spring, which sleeves the middle portion of the driving rod, and the resetting deviceis disposed between the driving rodand the apparatus framein the manner that the resetting deviceis held inside the moving channelof the apparatus frame. A bottom end of the resetting deviceis abutted on a rod body protruding portionof the driving rod, and an upper end of the resetting deviceis abutted on a frame body protruding portion, so that when pressing the upper end of the driving rodto drive the driving rodto move along the track formed by the moving channelof the apparatus frame, the rod body protruding portionof the driving rodand the frame body protruding portionof the apparatus framemutually compress the resetting deviceto allow the resetting deviceto accumulate the elastic potential energy by generating the elastic deformation. After the external force applied to the upper end of the driving rodis removed, the resetting devicedrives the driving rodto move along the track formed by the moving channelof the apparatus frameduring the process of restoring the initial state, so as to restore the driving rodto its initial position.
