technical field

The utility model relates to the field of sports equipment, in particular to an auxiliary device for badminton pace training.

Background technique

In badminton, doubles has an area of 40m ² per half, and singles exceeds 34m ² . Players must hit each other's balls that land anywhere in the area and return them before they hit the ground. The characteristics of badminton determine the importance of badminton footwork teaching. The traditional badminton footwork training method is that the athlete moves quickly to the designated position according to the direction of the coach's hand. The training in this way is more random, and the coaches must accompany the athletes to participate in the training. It lacks quantitative evaluation of the reaction speed of the athletes' running positions, and it is impossible to carry out technical statistics on the training effect after the training.

The Chinese invention patent with application number 200910038859.0 discloses an auxiliary device for badminton pace training, including a laser projector, a main controller and multiple position sensors. The laser projector is controlled by the main controller; the main controller and the position sensors are connected via wireless Data is transmitted by means of communication; the position sensor includes a base, an elastic rod, a single-chip circuit and an infrared reflective sensor, and the infrared reflective sensor is connected to the single-chip circuit; the elastic rod is fixed on the base and placed above the base; the infrared light emitted by the infrared reflective sensor Shoot upwards. This invention uses laser projection to guide athletes' running positions. It can not only arrange training programs in advance by coaches according to the characteristics of athletes, but also record and count the reaction time of athletes to each position during training. In order to evaluate the training results, formulate The next step training program provides a scientific basis.

When using the above-mentioned auxiliary device for badminton pace training for training, the athlete moves according to the projected pattern and hits the elastic rod of the position sensor at the corresponding position with the badminton racket. When the elastic rod is hit, it swings to reflect infrared light to infrared reflection. The single-chip microcomputer circuit sends the information that the elastic rod is hit (that is, the information that it is in place) to the main controller through wireless communication. According to the characteristics of badminton, when the ball is played in the front field and the middle field, the racket is usually stretched from the center of the court to the direction to hit the ball, while the back field position is usually hit from a high place, and the racket is swung from the back to the front. That is to say, the above-mentioned auxiliary device for badminton pace training can achieve better results when applied to the pace training of the front field and the midfield, but when it is applied to the pace training of the back field, the effect is very unsatisfactory. In addition, when using the above-mentioned auxiliary device for badminton pace training for training, it is necessary to hit the elastic rod with the racket frame, which is easy to cause damage to the badminton racket.

Utility model content

The utility model aims at the deficiencies of the prior art, and provides an auxiliary device for badminton pace training which has better training effect and will not damage the badminton racket.

The right arrow in the azimuth, the left rear arrow in the left rear azimuth, and the right rear arrow in the right rear azimuth are provided with a backlight corresponding to the transparent area on the back plate, and the backlight is controlled by the controller. The control method of the backlight can be that only the backlight in a certain direction emits light at the same time, that is, instructs the trainer to move to that direction. The controller trainer has run to the position, and the controller will control the position indicating device to indicate the next direction. Of course, the control method of the backlight can be that only the backlight in a certain direction flashes at the same time, while the backlight in other directions is always on. In this case, the trainer is required to move to the flashing direction.

Further, the transparent area also includes a circular area or a square area in the center, and a backlight is also provided at a corresponding position on the backboard, and the backlight is always bright, so that the trainer can identify the orientation more easily.

When the visible light laser is used, when the laser emits the laser beam, due to the scattering effect of the particles in the air, the laser beam can usually be seen by the human eye, so it is more conducive to the pace training of badminton. During pace training, usually hold a badminton racket, and swing the racket accordingly while running. When the utility model is applied, the racket is used to touch the laser beam while running. The speed of the racket is relatively slow, while the movement of the backcourt is usually the movement of the high ball, the speed of the swing is fast, the time for the racket frame to block the laser beam is short, the width of the frame is greater than 5mm, the laser The diameter of the beam is calculated by 2mm. If the swing speed is 500km/h, the time for the racket frame to completely block the laser beam is about 0.2ms, and the response time of the usual photodetector can reach the μs level. When the racket is swung vigorously in the backcourt, the auxiliary device of the utility model will not miss the judgment.

Further, the laser is a semiconductor laser. Semiconductor lasers are small and easy to control.

Further, the control flow of the controller is:

a) According to the predetermined training program or the training program randomly generated by the controller, control the position indicating device to display the pattern of the current training orientation;

b) Waiting for the response of the position sensor in the corresponding direction;
