Pulley force sensing device for retraining fitness equipment

This creation is about a motion force sensing device, especially a pulley force sensing device for heavy training fitness equipment.

In various types of sports, different people have different favorite sports. Some athletes prefer simpler sports (walking, hiking, jumping, running, cycling, etc.), while others prefer to exercise in combination with a variety of fitness equipment.

When an athlete uses fitness equipment to exercise, although the purpose of exercise can be achieved, it is impossible to understand and measure the amount of exercise. In the design of traditional fitness equipment, most of them only have simple exercise functions. When athletes use the fitness equipment, they cannot understand and accurately measure whether their exercise volume is appropriate.

In order to enable the athlete to know the amount of exercise while exercising, in the prior art, there have been sensing devices designed for people's exercise conditions. However, these conventional sensing devices still have some problems when measuring the movement condition of the athlete.

Only the number of round trips (REP) or counts (counts) can be counted. 5. The travel speed cannot be calculated accurately. 6. Can not automatically wake up function, power consumption. 7. The player's acceleration or deceleration cannot be calculated. 8. It is impossible to accurately calculate the time when the athlete applies force. 9. It is impossible to measure the travel speed and the weight of the weight at the same time in the same device. 10. The power of the user's movement cannot be measured on the same measuring device. 11. The structure is complex, the cost is high, and the maintenance is not easy. 12. Lack of advantages of stand-alone configuration.
