Description

Flywheel brake device for sports equipment

The invention relates to a flywheel braking device for sports equipment, in particular to a flywheel braking device for a sports equipment that interferes with the rotation of the flywheel through the braking device and thereby adjusts the driving force required for the rotation of the flywheel.

Moderate exercise is the only way to maintain health. However, modern people often have fewer opportunities to exercise outdoors because of limitations in venue, time or other factors, resulting in insufficient exercise, resulting in weaker body resistance and vulnerability to disease.

Therefore, there are many kinds of sports equipment on the market, and among the many sports equipments, the flywheel exercise bike can not only improve the heart and lung function, but also have a good effect on the back muscles, buttocks and lower limbs. In addition, the flywheel exercise bike can not only Make climbing and sprinting, and achieve different sports effects through vertical or reclining riding. Therefore, unlike ordinary bicycles, there is only a pedaling function. It will be boring when riding for a long time. Therefore, the flywheel exercise bike is more accepted by most people.

The movement effect of the flywheel exercise bike is derived from the weight of the resistance wheel. When the weight of the resistance wheel is heavier, the greater the power required by the user to step on the flywheel exercise bike, the resistance wheel that the general user initially chooses. The weight is mostly 18kg (less than 18kg, there is no sport effect), and when the user adapts to the current resistance wheel weight and wants to have better exercise effect, he must change the resistance wheel to heavier flywheel fitness. Car, however, the price of a flywheel exercise bike is at least It costs tens of thousands of Taiwan dollars, so it is a considerable burden for the average user.

In order to solve this problem, the general flywheel exercise bike will also be equipped with a resistance adjustment mechanism, so that the user can adjust the resistance of the flywheel when it rotates according to its own needs. With regard to the prior art of the resistance adjustment mechanism, for example, the US Patent Publication No. 2008/0096725 and the Patent No. 2012/0088638 both adjust the resistance of the flywheel by changing the relative position between the magnet and the flywheel. However, the two conventional patent cases also have the problems of complicated structure and difficult operation, and thus there is a need for improvement.

In addition, if the applicant applied for and approved the new patent No. M457074 on November 29, 2012, the main purpose is to use the braking unit to receive the power generated by the generating coil group through the power control unit and interact with the metal ring. After that, a braking force is generated and applied to the flywheel, and the braking force generated by the use of electric power and the action of the metal ring has the expected braking effect on the flywheel. However, the applicant believes that there is still improvement and improvement. In terms of performance, I thought that I would improve and innovate, and after painstaking research, I finally succeeded in developing and developing the flywheel brake device for this piece of sports equipment.

The main object of the present invention is to provide a flywheel brake device for a sports equipment that achieves an equivalent increase in the weight of the resistance wheel by adjusting the resistance.

A secondary object of the present invention is to provide a flywheel brake device for a sports equipment that can achieve different sports effects without replacing the resistance wheels of different weights.

It is still another object of the present invention to provide a flywheel brake device for a sports equipment that achieves different motion effects using a single flywheel sports car.

In order to achieve the above object, the flywheel brake device of the sports equipment of the present invention mainly comprises a a flywheel body, a braking device and a fixed bracket group, wherein a concentric circle is arranged around the outer edge of the axis of the flywheel body, and a resistance ring is arranged between the concentric circle ring and the outer ring of the flywheel body, the resistance ring Forming an accommodating space with the concentric metal ring, the fixing bracket set includes a positioning bracket and a fixing bracket, the positioning bracket is connected to the fixed shaft at one end, and the other end extends to the position of the accommodating space and the fixing bracket The braking device is covered and fixed in the accommodating space, and the magnetic force generated by the braking device acts on the resistance ring, so that the flywheel body cuts the eddy current damping effect generated by the magnetic field, thereby changing the resistance weight of the flywheel body, and the user can pass through the single flywheel body. Achieve different sports effects.
