When a practicer uses the exerciser to rotate the ball through the fingertips, the ball needs to be shot and accelerated, and when the ball is shot and accelerated, only the rotating force can be added to the rotating ball. Beginners often add unnecessary lateral force to cause the basketball to sway from side to side due to the inability to accurately control the direction of the force. The ball body is unstable after the racket ball is accelerated, the subsequent fancy ball rotating action is often difficult to complete, and the ball is generally shaken and falls after being wound to a half route. The trainees need to know that the ball patting gesture causes unstable ball bodies at that time, and can continuously and immediately improve the ball patting gesture until finding accurate patting points and force-applying techniques to enable the ball to stably rotate. Because the strength of the bat rotation cannot be intuitively and visually understood, the practice of the practicer can only rely on the feeling, so that the practicer can difficultly practice any flower-type spin for a long time.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1, the invention discloses an exerciser for quickly learning fancy spin balls, which comprises a bearing sleeve 10, a bearing 12, a ball support 30 and a finger support rod 40, wherein the ball support 30 and the finger support rod 40 are respectively arranged above and below the bearing sleeve 10. A battery 14 and a main control circuit board 11 for providing power are arranged in the bearing sleeve 10, and the exerciser is also provided with a reminding mechanism controlled by the main control circuit board 11; the reminding mechanism is composed of a detection device and a feedback device, wherein the detection device is used for collecting the movement data of the ball support 30, the detection device is electrically connected to the main control circuit board 11, and the feedback device is arranged on the bearing sleeve 10.

The detection device comprises a vibration sensor, an acceleration sensor and an angle sensor which are integrated on the main control circuit board 11. The three sensors are used for detecting whether the exerciser is too large in polarization when in use, and the fact that the exerciser is incorrect in the batting force and the batting point is mean by the fact that the exerciser cannot enable the ball body to stably rotate. The term "polarization" means that the sphere is deflected against a vertical axis perpendicular to the horizontal plane at the upper part of the sphere by a finger after being shot or is deviated from the original position in the horizontal direction, and the term "vibration" means vibration generated after the sphere is shot, the same words are agreed throughout the text), so that the factor with overlarge polarization is generated, and the inventor obtains three factors which influence the stability of the rotating sphere, such as the factor shown in fig. 5, the factor shown in fig. 6 and the factor shown in fig. 7 after research. As shown in fig. 5, before starting to spin, the exerciser needs to flap the ball to rotate on the ball support 30, and when the angle of the racket (larger than the tangent line) is too large, the too large angle of the flap causes the ball to generate horizontal leftward or rightward thrust on the ball support 30, so that the ball support 30 is quickly away from the racket point, and a horizontal offset with a certain acceleration is generated. And the acceleration sensor is used for detecting the acceleration of the exerciser and converting the acceleration into an electric signal to be sent to the main control unit of the main control circuit board 11 for processing. As shown in fig. 6, the force application point when the exerciser beats the ball is horizontally inclined from the ball, and when the force application direction angle of the exerciser to the ball is too high, the whole exerciser and the ball are pushed to incline. And the angle sensor is used for detecting the angle of the exerciser deviating from the vertical line perpendicular to the horizontal plane and converting it into an electrical signal to be transmitted to the main control unit of the main control circuit board 11. As shown in fig. 7, in order to make the ball body reach a qualified rotation speed to complete fancy ball-rotating, the exerciser needs to beat the ball body many times to accelerate the ball body, but an improper ball-beating drop point can make the exerciser vibrate, and when the vibration frequency is too high, the ball body can not rotate stably, generally, the upper and lower belts swing and vibrate. And the vibration sensor is used for detecting the vibration condition of the exerciser, converting the vibration condition into an electric signal and sending the electric signal to the main control unit of the main control circuit board 11 for processing.

As shown in fig. 4, the vibration sensor, the acceleration sensor, and the angle sensor as the detection devices are electrically connected to the input end of the main control unit, and the output end of the main control unit is electrically connected to the feedback device. The feedback device comprises a buzzer integrated on the main control circuit board 11 and LED lamp beads 102 arranged on the surface of the bearing sleeve 10, the main control unit receives electric signals of the sensors, and after the electric signals reach the triggering condition of overlarge polarization, the main control unit lights the LED lamp beads 102 and enables the buzzer to make a sound so as to remind a practicer that the racket ball moves and the strength of the practicer are wrong. The trainees can visually know the defects of the racket gestures and correct the racket gestures in real time without feeling. Thereby more quickly shooting out the stable positive starting rotary ball and putting the foundation of the fancy rotary ball. In the present invention, the detecting device further includes an angular velocity sensor for measuring the rotation speed of the ball tray 30, and the angular velocity sensor is electrically connected to the main control circuit board 11. To complete the fancy ball-rotating action, the ball body needs to rotate rapidly at the finger tip, so that the ball needs to be racked to meet the rotating speed requirement before the fancy ball-rotating action is carried out. The angular velocity sensor measures the rotation speed of the ball support 30 to obtain the current rotation speed of the ball, and converts the current rotation speed into an electric signal to be sent to the main control unit for processing. The outer surface of the bearing sleeve 10 is also provided with a display screen 101, the display screen 101 is connected to the output end of the main control unit, and the current rotating speed of the ball body or the average rotating speed after the ball rotation is stopped can be displayed during the ball rotation. The main control unit is also provided with a function selection module, the surface of the bearing sleeve 10 is provided with a key group 103 which is electrically connected with a function selection key of the main control circuit board 11 and a switch key, the function selection key and the display screen 101 are used in a matching way, the battery 14 supplies power to the electronic element of the exerciser, and the switch key is used for disconnecting or connecting the battery 14, so that the exerciser can automatically select whether to use the prompting function of the exerciser. The functions that the function selection module can set include speed standard-reaching reminding and timing reminding, and when the rotating speed measured by the angular velocity sensor reaches the standard, the main control unit activates the feedback device to remind a practicer. The timing reminding is that the master control unit activates the feedback device to remind the practicer after the exercise duration reaches the appointed time of the practicer. The rotating speed reaching the standard and the length of the designated time are adjusted by a practicer through the key group 103, and the display screen 101 assists in displaying the current adjusted content of the practicer. In the invention, the vibration sensor, the acceleration sensor, the angle sensor and the angular velocity sensor are all the prior art, and the working principle of the vibration sensor, the acceleration sensor, the angle sensor and the angular velocity sensor is not described in the technical scheme.

In the invention, the exerciser also comprises an auxiliary rotating mechanism. The auxiliary rotating mechanism comprises a first scheme and a second scheme.
