Description

Badminton Automatic Serving Machine with Improved Structure

technical field

The utility model belongs to the technical field of sports equipment for badminton teaching and training, in particular to a badminton automatic serving machine with improved structure.

Background technique

Badminton is one of the advantageous sports in our country, and it is loved by people of different ages. When performing badminton practice, it is usually necessary to feed the shuttlecock to the position of the practitioner by hitting or throwing by a coach or a skilled person familiar with badminton. Because the height, position and parabola of artificially hitting and throwing the ball will be different, it is not conducive to improving the skill of the ball learner and/or achieving the desired training purpose, and even the situation of getting twice the result with half the effort occurs. Using the badminton machine to serve the ball can make up for this deficiency to a certain extent, and can also significantly reduce the teaching intensity of the trainers and coaches, and even carry out self-training and sports without coaches and skilled persons, that is, Single batting practice.

In the published Chinese patent literature, it can be seen that all the technical information about the automatic shuttlecock serving machine, such as the utility model patent authorization announcement number CN203803081U, recommends "a kind of badminton serving device for teaching", and the invention patent application publication number provides "a kind of shuttlecock serving device". Badminton Serving Machine". Typical such as the "badminton serving machine" introduced by the authorized announcement number CN202777705U, although this CN202777705U can achieve the invention stated in paragraph 0003 of its specification, it has the following disadvantages: First, because it needs to be equipped to make the turntable rotate, it can be driven by the turntable. The motor that rotates the support bar, the motor that drives the gripper to rotate, the motor that drives the gripped badminton racket to move, the motor that drives the carrying plate to move, and the motor that drives the turntable to move, so the number of power mechanisms is large. It is not conducive to saving electric energy and is not conducive to low cost, and it is difficult to manufacture and assemble; secondly, because there are many transmission links, when any link is out of coordination, it will cause the failure of serving; The falling process of the shuttlecock is divided into two steps or two stages. First, the head of the shuttlecock is protruded from the bottom of the cylinder by the weight of the shuttlecock, and then the shuttlecock is clamped (taken out) by the gripper with a relatively complicated structure, so that the shuttlecock Once there is a time difference between the timing of free (automatic) falling by virtue of its gravity and the timing of gripping by the gripper, it will cause gripping failure. In particular, due to the particularity of the shape of the shuttlecock, if there is no external force, the feather of the shuttlecock is in contact with the wall of the cylinder, so it is usually difficult to fall out of the cylinder under its own weight. The diameter (inner diameter) of the barrel cavity is appropriately enlarged so that the feather of the shuttlecock and the barrel wall of the shuttlecock are in a state of contact and non-contact. The two shuttlecocks fell out of the cavity of the barrel together in an uncontrolled manner.

The above technical problems are eliminated by the technical solution of "automatic badminton serving machine" proposed by the invention patent application publication number CN104784913A. For details, please refer to paragraphs 0006 to 0016 of the specification of this CN104784913A. But still there is following shortcoming: one, because badminton racket is fixed on the drive shaft of badminton racket under the state of use, one end of badminton racket drive shaft is rotatably supported on the column, and the other end is transmission-connected with the racket serving drive mechanism, Therefore, when the racket drive mechanism drives the racket drive shaft and the racket drive shaft drives the badminton racket to serve the ball, the impact force of the badminton racket on the shuttlecock (that is, the power of the serve) is relatively weak, which affects the practice effect of the practitioner (or trainee); Two, because the drive shaft of the racket rotates 360°, the badminton racket also rotates 360° accordingly, so the serving efficiency is low, which affects the number of practice times per unit time of the practitioner (that is, the efficiency of practice is low); With the 360° rotation of the racket drive shaft, the air resistance is large, which is not conducive to saving the energy consumption of the racket drive mechanism, because the racket drive mechanism needs to be equipped with a motor with sufficient power. In view of this, it is necessary to continue to improve, and the technical solution to be introduced below is produced under this background.

Since the badminton racket 10 is fixed on the upper part of the racket fixed pendulum 7 by the racket screw 101, the ball dropped from the aforementioned rotary table by the badminton racket 10 is in the process of driving the racket fixed pendulum 7 by the connecting rod 82 to move forward and backward. The shuttlecock 9 percussion of hole 312 (also can claim to hit) and completes the action of serving. While the badminton racket 10 is serving the ball, the aforesaid turntable drive mechanism 24 is undoubtedly in working condition, so that the gear turntable 31 can rotate, and the ball-by-ball disc 61 goes down along the threaded mandrel 5 to ensure that the ball-by-ball 62 The shuttlecock 9 is expelled from the ball drop hole 312 of the rotary disc and fed to the badminton racket 10 . Taking this embodiment as an example (the number of a set of ball storage tubes 32 is 4), the gear rotary plate 31 will output a shuttlecock 9 every time it rotates 90°, and when the gear rotary plate 31 rotates once, it will rotate 360°, then successively Four shuttlecocks 9 are output, the badminton racket 10 completes four servings, and the practitioner opposite to the badminton racket 10 completes four catching actions accordingly. If the number of one group of ball storage tubes 32 is three (distributed at intervals of 120° from each other), then the gear rotating disk 31 rotates 360° (one circle) so that three shuttlecocks 9 are output, and so on. The rotation speed of the gear rotary disc 31 is determined by the rotation speed of the motor 42 , and the rotation speed of the motor 42 is controlled by the electrical controller 212 .
