Description

A badminton automatic serving machine

technical field

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

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 automatic serving machine to serve the ball can make up for the aforementioned deficiencies 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 unrestrained 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 this CN104784913A still has the following shortcomings: one, because the badminton racket is fixed on the drive shaft of the badminton racket under the state of use, one end of the drive shaft of the badminton racket is rotatably supported on the column, and the other end is connected to the drive mechanism of the racket for transmission. Therefore, when the racket drive mechanism drives the racket drive shaft and the racket drive shaft drives the badminton racket to serve, 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) ; Its two, because racket driving shaft is done 360 ° of revolutions, thereby badminton racket is also made 360 ° of revolutions correspondingly, thereby service efficiency is low, influences the number of times of practicing the ball per unit time of the practitioner (i.e. the efficiency of practicing the ball is low); The badminton racket rotates 360° with the drive shaft of the racket, so it is subjected to large air resistance, 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; It cannot be adjusted according to the needs, so the parabolic landing point of badminton is single, that is, the hitting mode is rigid, and it is not possible to freely choose among the three hitting modes of front court ball, flat ball and back ball, which is not conducive to comprehensive practice of badminton. Fifth, since the ball-carrying and ball-feeding mechanism is composed of four parts: the ball-carrying mechanism, the rotary disk drive mechanism, the screw rod and the ball-chasing mechanism, the structure is relatively complicated, which is not conducive to manufacturing and assembly, and is not convenient Reflect the cheapness of the economy. In view of not being limited to these shortcomings described above, there is still a need for further improvement. For this reason, the applicant has made a useful design and carried out a computer simulation deduction test under taking confidentiality measures, and the result proves that it is practicable.
