A magnetic control brake assembly is characterized by comprising a main body part (1) with one end hinged to a frame, a plurality of magnets (2) arranged on the wall surface of the main body part (1) and a brake block (3) arranged at the other end of the main body part (1), wherein the magnets (2) and the brake block (3) are both positioned between the main body part (1) and the arc-shaped surface of a flywheel (300); the main body piece (1) is provided with a trigger piece, the main body piece (1) can rotate around a hinge point to be close to or far away from an arc-shaped surface of the flywheel (300) by driving the trigger piece, and the trigger piece rotates until the brake block (3) is abutted and locked with the flywheel (300); the main body (1) can be restored to the initial position without being driven by a trigger.

2. The magnetically controlled brake assembly according to claim 1, wherein when the main body member (1) is in the initial position, the clearance between the magnet (2) disposed on the main body member (1) and the arc-shaped surface of the flywheel (300) is the largest, and the magnetic attraction resistance of the flywheel (300) is the smallest.

3. The magnetically controlled brake assembly according to claim 2, characterized in that the end of the body member (1) adjacent to the brake block (3) is provided with a resilient member, the other end of the resilient member being connected to the frame.

4. The magnetically controlled brake assembly according to claim 1, wherein the trigger member is connected to the main body member (1) at one end, and the force applied to the main body member (1) by the trigger member is opposite to the force applied to the main body member (1) by the elastic member due to deformation.

5. The magnetically controlled brake assembly according to claim 4, wherein the triggering member is a pulling rope (4), the end of the pulling rope (4) is connected to the body member (1), and the body member (1) is pulled towards the flywheel (300).

6. The magnetically controlled brake assembly according to claim 1, characterized in that the main body (1) is in the shape of an arc-shaped bent block, and the bending amplitude of the main body (1) is consistent with the arc-shaped surface of the flywheel (300); the main body part (1) is driven by the trigger part, and the brake block (3) is in surface contact with the arc-shaped surface of the flywheel (300).

7. The magnetic control brake assembly according to claim 3, wherein a hanging portion extends outward from an end of the main body member (1), one end of the elastic member is hung on the hanging portion, and an end of the triggering member is disposed on the hanging portion.

8. An exercise apparatus comprising a frame, a flywheel (300) and a magnetically controlled brake assembly according to any one of claims 1 to 7.
