Description

Basketball training machine

Technical Field

The invention relates to a basketball training machine, belonging to the technical field of sports equipment.

Background technique

Basketball is a sport with high ornamental value and mass participation. Shooting is the most important way to score in basketball games. Athletes need a lot of shooting practice to improve their hit rate. Traditional shooting training is divided into self-shooting and self-rebounding type and sparring assisted type. Self-shooting and self-rebounding type wastes time and energy to pick up the ball, while sparring assisted type cannot practice by oneself and wastes human resources. Currently, the basketball training machines on the market are expensive, occupy a large area, and cannot be used for both men's and women's basketballs, which have large differences in size.

In addition, the basketball launching schemes of the existing basketball training machine include high-speed cylinder push shooting, high-speed cylinder kick shooting (using gear rack to reduce force and increase speed), spring launching and friction wheel launching. The two schemes using cylinders have severe vibrations and require air pumps to continuously replenish gas, which makes a lot of noise and is also expensive. The spring launch has a slow serve speed and is difficult to launch beyond the three-point line. Therefore, friction launch stands out among these schemes, but friction wheel launch has high requirements for the distance, shape, and angle of the friction wheel. In addition, the existing technology launches basketballs through friction, which will reduce the launch speed and launch distance of the basketball due to the friction between the friction wheel and the basketball.

Beneficial Effects

(1) The basketball training machine of the present invention has a low processing cost. The friction wheels are arranged up and down to avoid the basketball from deviating to the left or right due to speed difference. By adjusting the speed and speed difference of the two friction wheels, the distance of the basketball launch and the angle with the ground when launching can be controlled. The rotating mechanism can control the angle of the basketball launch to the left and right. The ball collection mechanism can automatically recover the basketball that has been thrown in and the basketball that has not been thrown in. It has the advantages of high degree of automation, low cost, wide application range, and short development cycle.

(2) The basketball training machine of the present invention can automatically collect and store basketballs and launch them to a designated location.

(3) In the present invention, when the push plate pushes the basketball to pass through the multiple bearings and move toward the serving plate, the basketball first passes through the multiple bearings and then moves toward the friction wheel. In the process of the basketball passing through the multiple bearings, not only can the position of the basketball be adjusted so that the basketball can be accurately pushed to the center position of the two friction wheels; in the process of the basketball passing through the multiple bearings, the sliding effect of the bearings on the basketball can effectively reduce the friction between the friction wheel and the basketball, thereby increasing the launching speed and launching distance of the basketball.

(4) The basketball training machine of the present invention is made of plates and aluminum profiles connected by bolts; it is light in weight, low in cost, stable in structure, and easy to modify; the use of aluminum profiles makes it easy to adjust the distance between the two friction wheels, and can be used for training basketballs of different sizes.

(5) The mobile chassis of the present invention uses flat wheels with brakes, which are low-cost, convenient, and strong, and are easy to move and fix.

(6) The serving mechanism of the present invention uses a motor to drive the gear to move along the rack, driving the push plate to push the basketball to move toward the friction wheel. It has low cost, compact structure, and easy control of forward and backward distances.

(7) The rotating mechanism of the present invention uses a motor to drive the pinion to rotate along the inner gear ring, which has low cost and compact structure, and can automatically calibrate back to the original position under external interference.

(8) The ball collecting mechanism of the present invention can be adjusted up and down, and can be used in conjunction with a basketball recovery rack on the market to recover basketballs.

(9) The mortise and tenon connection structures between the track plate and the first connecting plate of the present invention and the ball receiving plate are respectively combined with the profiles. As the parts that are subjected to the most severe force and vibration when the basketball is dropped, the mortise and tenon structure combined with the profiles greatly enhances the stability of the basketball training machine, fixes the parts tightly and accurately together, and makes the entire structure more earthquake-resistant and firm.

(10) The present invention designs a basketball training machine with low cost, ingenious structure and convenient adjustment for athletes to use, so that athletes can make the best use of their time and physical strength, improve their shooting level and enhance their competitive state.

(11) The rotational speeds of the first friction wheel and the second friction wheel of the present invention are the same or different. Since the two friction wheels are driven to rotate by the outer rotor brushless motors inside them, the rotational speeds of the two friction wheels can be adjusted separately. By adjusting the speeds of the two friction wheels and the speed difference, the distance of the basketball launch and the angle with the ground during the launch can be controlled.

By combining the mortise and tenon connection structure between the track plate 302 and the first connecting plate 5 and the ball receiving plate 46 respectively with the profile 7, the mortise and tenon structure combined with the profile 7, as the part that is subjected to the most severe force and vibration when the basketball is dropped, greatly enhances the stability of the basketball training machine, and fixes the parts tightly and accurately together, making the entire structure more earthquake-resistant and firm.

As shown in Fig. 5-9, the serving plate 301 and the limiting plate 309 are fixedly connected by a friction wheel fixing seat 306, and two friction wheel fixing seats 306 are connected to the upper and lower sides of the serving plate 301.
