A magnet 320 is installed on the side of the magnet frame 310 close to the inertia wheel 100 , which is hinged on the mounting bracket 200 . The roller body 522 abuts on the track 311 of the magnet frame 310 , and the track 311 is an inclined track. It is inclined from the mounting bracket 200 toward the inertia wheel 100 to drive the magnet frame 310 to rotate and displace toward the inertia wheel 100 ; the magnet frame 310 is arc-shaped toward the side of the inertia wheel 100 , and The side surfaces are distributed concentrically with the inertia wheel. Specifically, the bottom plate and two side walls of the magnet frame 310 are integrally connected, the bottom plate is an arc-shaped plate body, which is distributed concentrically with the inertia wheel 100 , and one end of the bottom plate is connected to the mounting bracket 200 through the hinge shaft 230 .

The working principle of the electric adjustment device for the resistance gear of the inertia wheel is as follows:

The motor 400 drives the screw 510 to rotate, and the screw 510 drives the roller bracket 521 to slide and displace along the axis of the screw 510. At this time, the sliding lever 610 of the sliding resistor 600 is driven by the roller bracket 521 for sliding displacement, thereby adjusting the sliding resistor 600. At the same time, the roller The main body 522 is mounted on the roller bracket 521 and is displaced along the direction of the track 311 of the magnet frame 310.

The sliding lever 610 is slidably displaced between point A and point B;

The motor 400 is started, and the driving screw 510 rotates, so that the roller bracket 521 moves away from the horse 400 in the axial direction of the screw 510 (ie, the tangential direction of the inertia wheel 100 ) to a sliding displacement, and drives the roller body 522 to ascend and slide along the direction of the track 311 (ie, toward FIG. 4 ).

In addition, when the motor 400 is activated, the driving screw 510 rotates in the reverse direction, so that the roller bracket 521 slides and displaces close to the motor 400 in the axial direction of the screw 510 (ie, the tangential direction of the inertia wheel 100 ), and drives the roller body 522 to descend and slide in the direction of the track 311 , thereby resisting the sliding movement of the roller body 522 . The pressing magnet frame 310 drives the magnet 320 to rotate and displace toward the mounting bracket 200 , thereby increasing the distance between the magnet 320 and the inertia wheel 100 .

It should be noted that the distance sensor can be adjusted according to the actual situation, and its purpose is to measure the distance between the magnet and the inertia wheel. In this embodiment, the distance sensor is a potentiometer, which is installed on the output shaft of the motor 400 for measuring the distance between the magnet and the inertia wheel.
