Abstract

Our current invention is a device which detects an exerciser's dynamic power output in a real-time fashion. The horizontal and vertical forces (including body weight), distribution of center of gravity and rotational force of a plate reacted to the exerciser's action on-board, will be detected simultaneously by the load cells installed in the middle of each wall and at each floor corner of an accommodating box underneath, and by the torque meter in the center of another plate stacked below the box, respectively.

Description

Motion dynamic detection platform

The invention relates to a force detecting device; the device uses the principle of Newton's third law (reaction force in response to force) to load the force spindle and the torque meter thereon, and instantly detect the motion thereon. The process of applying force output and changing the center of gravity. Therefore, the present invention contributes to scientific research and training related to exercise.

Previous attempts to meet this goal have been designed with independent pedals, and on-board detection instruments, such as gauge gauges or load cells, combined with signal displays or data collection and analysis software, respectively During the display or measurement of the movements of the athletes (such as golf swings, etc.), the balance of the body, the distribution of the center of gravity, the movement of the weight, and the exertion of the feet.

The simple device disclosed in the U.S. Patent Publication No. 3,609,022 (Kretsinger Jun), published on Feb. 9, 1965, shows the weight of the weight of the ball when the ball is displayed. Subsequent devices such as US Patent No. 5118112 (Bregman, et al.), published on June 2, 1992, US Patent No. 5150902 (Heisler Jun), published on September 29, 1992, and the beauty of the announcement on May 30, 1995 Patent No. 4,541, 956 (Cromarty Jun) and US Patent No. 6,402,635 (Nesbit, et al., et al.), published on June 11, 2002, may determine the total weight of each foot. The amount, but can not provide the data of the body's center of gravity, and the pedal may slip open during use.

Among these devices, especially Heisler Jun and Cromarty Jun and another US Patent No. 6039658 (Cecchin Jun) announced on March 21, 2000, although they can determine the total weight of each foot, they cannot distinguish between different feet. The distribution of parts, such as the toe and the heel or the inside and outside. Although the US Patent No. 7946928 (Mooney Jun) announced on May 24, 2011 has the above functions (measuring the weight distribution of different parts of the foot), the center of gravity cannot be measured because the pedals are separated and movable. The stacking pedal design of the US Patent No. 8915149 (Berme Jun) announced on December 23, 2014 can calculate the state of gravity of the body.

In short, the prior art, based on the individual foot or the weight of the two feet, can only reveal the athlete's body balance, center of gravity distribution, weight movement and biped force; however, in fact, almost all movements except horizontal In addition to moving up and down, it also includes the body's twisting or turning, which is also undetectable by previous devices. The innovative invention uses Newton's third law principle to install the design of the load-bearing ingot and the torque meter on the stacking plate platform, and then it can be completed.

Scientific research and training related to sports relies on reliable monitoring instruments to provide and record accurate data for analysis, such as high-speed photography or film technology. However, these technologies can only provide data on limb movement rather than power output. Therefore, the development of motion motion detection devices is crucial.

In addition to the synergy between the nerves, muscles and bones of various parts of the body, the movement of the athletes also depends on the friction between the feet (or the body) and the ground; this is why it is difficult to move on the slippery surface, or even because of the center of gravity. Stable and fall, as well as the surface of the sports sole or sports field Study the reasons for slip resistance and effective resistance. The physics theory behind it is nothing more than Newton's Third Low: any action is accompanied by an equal amount of opposite reaction; for example, walking relies on the foot to force the ground backwards. Then, the reaction force accompanying the ground pushes forward, and the moving force depends on the friction (or coefficient of friction) between it and the ground. The upward bounce is made by bending the knees of the legs and then pushing up by the reaction force accompanying the ground; the linear force is so, and the torsional force is also the same. Therefore, if the principle can be used to measure the force or friction between the body and the ground, the state of the body's force (or power output) can be reflected.

As in the previous device design, a force device, such as a load cell, can be placed under the plate (the force plate or simply the force plate) on which the sole or the sole of the foot is pressed, and the vertical force of the body can be measured. The force force (or vertical force, such as the weightless state is the weight of the foot); so the force spindle is placed under the four corners of the rectangular force plate of the foot (or bearer), then you can synchronize The vertical force sum and the center of gravity distribution (or the distribution of center of gravity) are measured, such as the center of gravity shifts to the force, the center of gravity is equal, and the center of gravity does not change.

In view of this, if the load pin is placed at each midpoint around the side of the force plate, the horizontal force of the plate should be measured. If the left side moves, the right side of the ingot is forced, and the left side of the ingot is forced. Forced, etc., and so on; therefore, as shown in the figure, the present invention places the force plate in a shallow box (load box or simply a box) that can accommodate the board, and separates the load spindles In the middle of the four walls of the box and the four corners of the box (ie, below the force plate), when the box is in a fixed state, the horizontal and vertical force of the force plate (or the sum of the bodies) can be measured separately.

In a nutshell, the rotational or torsional forces can also be brewed as usual. As shown in the figure, if the force plate and the combo box combination can be stacked on a flat plate (torque plate or abbreviated plate), the bottom of the box and the center of the torsion plate are connected by a torque meter, and the lining is fixedly distributed. Rolling steel balls in four corners In order to support and remove the friction, when the torsion plate is in a fixed state, the torque of the cartridge (or the sum of the bodies) can be measured by the torque meter on the torsion plate.

Finally, as shown in the figure, in order to strengthen the structure and stability of the platform, the upper part of the force plate and the lower part of the torsion plate are respectively locked with locks, and the protection and the reinforcement frame are fixed above and below the lotus box. The bottom corners of the torsion plate are provided with non-slip feet that can be independently adjusted to stabilize the platform and adjust its horizontal state.

This uses Newton's third law, combined with the simple platform design of the upper and lower stacking force plates, the box and the torsion plate, supplemented by the ingeniously mounted load spindle and torque meter, which can instantly detect the athletes on the move ( Such as vertical, horizontal and torsion), the total force application process and the distribution of the center of gravity, not only fully fill the gaps and shortcomings of all previous inventions, but also make a revolutionary breakthrough in the invention of these fields.

Furthermore, the present invention (or its underlying principles) applies not only to all fixed-point sports in contact with the ground, such as a high-ball swing, a baseball swing, a tennis or billiard swing, a start, a jump (long jump, a shot or a dive), Feet (kicking), throwing, punching and kicking, etc., can also be used for mobile sports (such as stepping on a series of platforms during running or walking), so it can be used in a wide range of applications. Body movements such as ball, track and field, gymnastics, fitness, rehabilitation, dance, martial arts and fighting.

Moreover, the present invention can also match the size or material of the corresponding platform according to the type of exercise, strength and force application, and adjust or replace the installation position, sensing range and data collection frequency of the force sensing device. Once combined with the data collection, analysis and recording of computer hardware and software and the immediate feedback of the display, it can provide a comparison or review of the action or reference data. Finally, the present invention has the advantages of simple structure, easy assembly, maintenance, and portability and use.
