Description

Technical Field

[0001] This invention belongs to the field of basketball training, specifically a device for basketball passing training. Background Technology

[0002] According to the patent document with authorization announcement number "CN211561773U" and invention title "A Passing Training Device for Basketball Training," the description states that: the mobility of the entire device can be improved by the moving wheels at the lower end of the load-bearing plate; the support base can support the entire device after it has been moved to a designated position. The support base is a bolt structure. When the entire device has been moved to the designated position, rotating the bolts will lift the moving wheels off the ground and support the load-bearing plate. A rotating wheel and a connecting rod are connected; the connecting rod is connected to a first connecting rod, the first connecting rod is connected to a second connecting rod, and the second connecting rod is connected to the basketball rim. Rotating the rotating wheel causes it to rotate in the vertical plane, thereby driving the basketball rim to rotate in the vertical plane. When the rotating wheel rotates to a certain angle, a limiting strip will... The rotating wheel is fixed to the limiting frame. Since the limiting frame is connected to the support column via a support plate, and the support column is connected to the load-bearing plate, the longitudinal placement angle of the basketball hoop can be adjusted and fixed. A concave block is connected via a second connecting rod. The concave block is connected to a connecting block via a spring. The connecting block is connected to the limiting block via a push plate. Pushing the push plate upwards disengages the limiting block from the corner frame. Rotating the second connecting rod causes the basketball hoop connected to it to rotate a certain angle on the horizontal plane. When the second connecting rod reaches the desired angle, the limiting block is re-fixed to the corner frame. Therefore, the lateral placement angle of the basketball hoop can be adjusted and fixed. The entire device increases training content and improves training effectiveness by adjusting the placement angle of the basketball hoop. However, the following drawbacks still exist:

[0003] When conducting basketball passing training, it is inconvenient to pass the ball in different directions, and it is inconvenient to pass the ball to athletes in different directions.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention allows the ball-launching tube to rotate and tilt in all directions on the support base. The ball-launching tube is provided with pull ropes at equal angles around its circumference. The rotating ring drives the pressure cam to move above each pressure plate, and then the pull ropes pull the ball-launching tube to rotate in the corresponding direction, so that the basketball can be thrown in all directions. The receiving player then passes the ball back to the outer wall of the ball-launching tube, which facilitates passing training for players in all directions.

[0019] 2. In this invention, the ball-launching tube is set inside the collection tray. After the basketball is passed back, it can enter the collection tray. The inner wall of the collection tray is provided with a conical slope. The end of the conical slope near the ball-launching tube is inclined downward. At the same time, the ball-launching tube can move downward along the bottom tube so that its top wall is flush with the bottom of the conical slope, which facilitates the return of the basketball to its original position and facilitates subsequent basketball passing training, thereby improving the training efficiency of athletes in passing.

[0020] 3. In this invention, one end of the pull rope is connected to the internal plate inside the guide block. When the ball-serving tube is pulled and rotated, the contact point separates from the conductive strip, causing the locking rod to leave the slot, which facilitates the rotation of the ball-serving tube. After the ball-serving tube rotates back, the contact point re-contacts the conductive strip, causing the locking rod to lock into the slot, ensuring the vertical state of the ball-serving tube and preventing the ball-serving tube from tilting under the pressure of the side of the basketball. This also makes it easier for the basketball to return to its position when the ball-serving tube moves downward.

[0021] 4. In this invention, the pressing cam is driven by a second motor to rotate. After rotation, the height of the bottom wall of the pressing cam can be adjusted, thereby adjusting the downward pushing distance of the pressure plate when the pressing cam moves to the position corresponding to the pressure plate. This indirectly adjusts the rotation tilt angle of the ball launching tube and the throwing angle of the basketball, so that it can be adapted to the distance between the athlete and the equipment.

[0038] A support base 401 is provided below the serving tube 301. The outer diameter of the support base 401 is the same as that of the serving tube 301. A spherical groove 402 is provided inside the support base 401. A top groove 403 is provided at the top of the spherical groove 402.

A support column 405 is fixedly installed at the top of the spherical block 404. The top of the support column 405 is fixedly connected to the bottom of the serving tube 301. The diameter of the support column 405 is smaller than that of the inner diameter of the top groove 403. A snap-fit ​​positioning assembly 5 is provided between the serving tube 301 and the support base 401.

[0039] The snap-fit ​​positioning assembly 5 includes symmetrically arranged movable grooves 501 inside the serving tube 301. The movable grooves 501 are located below the inner cavity of the serving tube 301. A movable block 502 is movably installed inside the movable grooves 501. A locking rod 503 is fixedly installed at the bottom end of the movable block 502. The bottom end of the locking rod 503 extends through to the bottom of the serving tube 301 and snaps into the inside of a locking slot 508. The locking slot 508 is symmetrically arranged at the top of the support base 401. A third spring 504 is fixedly installed at the top end of the movable block 502. The top end of the third spring 504 is connected to the movable groove 501. The inner top wall is fixedly connected, the movable block 502 is equipped with a second magnet 507, the inner top wall of the movable groove 501 is fixedly installed with a second electromagnet 506, the inner walls of the two sides of the side guide groove 406 are symmetrically equipped with conductive strips 509 along their length direction, the conductive strips 509 of two adjacent side guide grooves 406 are connected in series by wires, and two second electromagnets 506 and a second power supply are connected in series between the two conductive strips 509. The two conductive strips 509 in the same side guide groove 406 are provided with an on / off control component 510 between the guide block 407 and the guide strip 509.

[0040] The on / off control component 510 includes an internal groove 5101 formed inside the guide block 407, side grooves 5102 symmetrically formed on both sides of the internal groove 5101, an internal plate 5103 movably mounted inside the internal groove 5101, and contacts 5104 symmetrically mounted at both ends of the internal plate 5103.

One end of 5105 is fixedly connected to the inner wall of the inner groove 5101, and one end of the pull rope 408 is connected to the inner plate 5103 inside the guide block 407. When the ball-serving tube 301 is pulled and rotated, the contact point 5104 separates from the conductive strip 509, causing the locking rod 503 to leave the slot 508, which facilitates the rotation of the ball-serving tube 301. After the ball-serving tube 301 rotates, the contact point 5104 re-contacts the conductive strip 509, causing the locking rod 503 to be locked into the slot 508, ensuring the vertical state of the ball-serving tube 301 and preventing the ball-serving tube 301 from tilting under the pressure of the side of the basketball, which facilitates the return of the basketball to its position when the ball-serving tube 301 moves downward.

[0041] The rotation drive assembly 6 includes a fixing ring 601 sleeved on the outside of the collection tray 1. The fixing ring 601 is located above the side slide groove 412. A fixing block 602 is installed at equal angles on the inner side of the fixing ring 601. The fixing block 602 is fixedly connected to the outer wall of the collection tray 1. An annular groove 603 is opened inside the fixing ring 601 and extends to the circumferential outer side of the fixing ring 601. A rotating ring 604 is rotatably installed inside the annular groove 603. The outer diameter of the rotating ring 604 is larger than the outer diameter of the fixing ring 601. A pressure block 613 is installed at the top of the pressure plate 411. Teeth 605 are provided at equal angles on the bottom wall of the rotating ring 604. A bottom gear 606 is provided below the rotating ring 604. The bottom gear 606 meshes with the teeth 605. The bottom gear 606 is fixedly connected to the output shaft of the first motor 607. The first motor 607 is fixedly installed on the fixing ring 601.

[0042] A pressing cam 608 is provided on one side of the rotating ring 604. The ball-launching tube 301 can rotate and tilt in all directions on the support base 401. Pull ropes 408 are provided at equal angles around the circumference of the ball-launching tube 301. The rotation of the rotating ring 604 drives the pressing cam 608 to move above each pressure plate 411, and then pulls the ball-launching tube 301 to rotate in the corresponding direction through the pull ropes 408, so that the basketball can be thrown in all directions, which is convenient for passing training to athletes in all directions. A rotating shaft 609 is fixedly installed on the pressing cam 608. The rotating shaft 609 is rotatably connected to the rotating ring 604. A driven gear 610 is coaxially installed on the rotating shaft 609. A drive gear 611 is meshed above the driven gear 610. The drive gear 611 is fixedly connected to the output shaft of the second motor 612. The second motor 612 is fixedly mounted on the rotating ring 604. The pressing cam 608 is driven by the second motor 612 to rotate. After rotation, the height of the bottom wall of the pressing cam 608 can be adjusted. Thus, when the pressing cam 608 moves to the position corresponding to the pressure plate 411, the downward pushing distance of the pressure plate 411 is adjusted, which indirectly adjusts the rotation tilt angle of the ball launching tube 301 and the throwing angle of the basketball, thereby facilitating multi-angle basketball passing training for athletes.

[0043] Both the inner wall of the conical inclined surface 308 and the outer wall of the ball-launching tube 301 are equipped with buffer pads. The buffer pads can effectively cushion the return basketball, allowing it to land effectively inside the collection tray 1 and preventing the basketball from bouncing out of the collection tray 1.

[0044] The collecting tray 1 has ball-blocking nets 7 installed at equal angles on its circumferential top wall. The number of ball-blocking nets 7 is the same as the number of pressure plates 411, and the number is even. In this application, there are six. The pressure plates 411 are set between two adjacent ball-blocking nets 7, and the gap between two adjacent ball-blocking nets 7 is equal to the diameter of the serving tube 301, so that a passing channel is formed between two adjacent ball-blocking nets 7. When the basketball is accurately returned, the basketball is blocked by the outer wall of the serving tube 301 and falls into the collecting tray 1. When the basketball is deviated from its course, the basketball grazes the side of the serving tube 301. At this time, the basketball will hit the opposite ball-blocking net 7, which will intercept the basketball and make it fall back into the collecting tray 1, which is convenient for collecting the basketball.

[0045] Working principle: When in use, the collection tray 1 is moved to the training ground via the movable seat 2, which consists of a base and a self-locking wheel. After being moved to the training ground, the self-locking wheel is locked to fix the equipment.

[0046] The first power supply and the second power supply circuit are connected, and the circuit is controlled by the controller. The second power supply is in the normally open state. At this time, under the elastic force of the fourth spring 5105, the internal plate 5103 makes the two contacts 5104 able to contact the conductive strips 509 on both sides, so that the second electromagnet 506 is in the energized state and generates a repulsive force on the second magnetic block 507, so that the locking rod 503 is inserted into the slot 508, and the support base 401 and the ball launching tube 301 are positioned so that the ball launching tube 301 and the support base 401 are coaxially set.

[0047] Then, the athletes who need to perform basketball passing training are positioned and stand along the pressure plate 411 set upward around the collection plate. The number of pressure plates 411 is the same as the number of athletes. This application has six pressure plates 411, which can be used to train six athletes in basketball passing.

[0048] The controller controls the first motor 607 to turn on and off. When the first motor 607 is turned on, it drives the bottom gear 606 to rotate. Since the bottom gear 606 is meshed with the teeth 605, it drives the rotating ring 604 to rotate on the outside of the collection plate 1, which in turn drives the pressing cam 608 to move. This causes the pressing cam 608 to move and stop continuously. The stopping position of the pressing cam 608 is located above the pressure plate 411 and in the middle of two adjacent pressure plates 411. That is, when the pressing cam 608 rotates around the collection plate 1, it can stop moving in twelve positions around the collection plate 1, including each pressure plate 411 and the middle of two adjacent pressure plates 411.

[0049] In its original state, the pressing cam 608 is positioned between two adjacent pressure plates 411. When the basketball is placed inside the launching tube 301, as the pressing cam 608 moves with the rotating ring 604 to above one of the pressure plates 411, the pressing cam 608 exerts pressure on the pressure block 613, pushing the pressure plate 411 downward. Then, through the pull rope 408 and the guide block 407, the launching tube 301 is pulled to rotate towards the corresponding pressure plate 411. At the same time, the controller controls the first electromagnet 305 to be energized, which attracts the first magnetic block 304, causing the push plate 302 to move downward, compressing the first spring 303. Then, the controller controls the first electromagnet 305 to be de-energized. At this time, the push plate 302 moves back under the elastic force of the first spring 303, thereby generating a pushing force on the basketball, causing the basketball to be thrown towards the athlete in the corresponding direction. The athlete needs to catch the basketball after it is thrown.

[0050] After the pull rope 408 exerts a pulling force on the guide block 407, the internal plate 5103 is first pulled to move, causing the contact 5104 to separate from the conductive strip 509. At this time, the circuit of the second electromagnet 506 is disconnected. In the original state, the second electromagnet 506 generates a repulsive force on the second magnetic block 507, and the third spring 504 is in a stretched state. At this time, the locking rod 503 retracts upward under the elastic force of the third spring 504, causing the ball launching tube 301 to disengage from the support base 401 and make it easier for the ball launching tube 301 to rotate.

[0051] After the basketball is thrown, the rotating ring 604 continues to rotate, causing the pressing cam 608 to rotate to the middle position of another set of two adjacent pressure plates 411. After the pressing cam 608 separates from the pressure plates 411, each pressure plate 411 moves back under the elastic force of the side slide groove 412. Under the pulling force in all directions, the ball launching tube 301 rotates back to the coaxial state with the support base 401. At this time, the internal plate 5103 moves back relative to the guide block 407, so that the contact point 5104 re-contacts the conductive strip 509, thereby re-energizing the second electromagnet 506 and causing the locking rod 503 to move downward and lock into the locking groove 508 to fix the ball launching tube 301.

[0052] At this point, the player receiving the basketball passes it back towards the outer wall of the serving tube 301, aiming at the outer wall to ensure the basketball hits it as hard as possible. The basketball then bounces into the inside of the collecting tray 1. Cushioning pads are installed on both the inner wall of the conical ramp 308 and the outer wall of the serving tube 301. These pads effectively cushion the return of the basketball, ensuring it lands safely inside the collecting tray 1 and preventing it from bouncing out. The conical ramp 308 on the inner side of the collecting tray 1 causes the basketball to roll along it towards the serving tube 301 after entering the tray. At this moment, the hydraulic cylinder 3 is activated. 07. Pull the support base 401 and the ball-launching tube 301 downwards until the top wall of the ball-launching tube 301 is flush with the bottom of the conical inclined surface 308. At this time, the basketball can roll into the ball-launching tube 301, which is convenient for collecting the basketball and facilitating subsequent passing training. After the basketball enters the ball-launching tube 301, the ball-launching tube 301 moves upwards under the drive of the hydraulic cylinder 307. During the process of the basketball passing back and impacting the side wall of the ball-launching tube 301, the ball-launching tube 301 and the support base 401 are fixed by a snap-fit, which avoids the ball-launching tube 301 from rotating due to the side pressure of the basketball, making it convenient for the ball-launching tube 301 to enter the bottom tube 306 to complete the return of the basketball.

[0053] During the longitudinal movement of the ball-launching tube 301, the guide block 407 moves relative to the ball-launching tube 301 along the side guide groove 406, so that the movement of the ball-launching tube 301 will not affect the position of the pressure plate 411. At the same time, the pull rope 408 is limited by the limit buckle 410 set on the conical inclined surface to ensure the stability of the movement of the pull rope 408.

[0054] After the ball-serving tube 301 moves upward, the rotating ring 604 continues to move, causing the pressing cam 608 to move above the next pressure plate 411, causing the ball-serving tube 301 to rotate towards another athlete. Then, the above operation is repeated to train athletes in various directions to pass basketball.

[0055] Meanwhile, the pressure cam 608 can be rotated and adjusted by the second motor 612. After the second motor 612 rotates, it drives the drive gear 611 to rotate. The drive gear 611 meshes with the driven gear 610 on the rotating shaft 609, thereby driving the pressure cam 608 to rotate. When the pressure cam 608 moves above the pressure plate 411, it adjusts the downward pushing distance of the pressure plate 411, thereby adjusting the rotation angle of the ball launcher 301, and then adjusting the throwing angle of the basketball. This allows for adjustment based on the distance between the athlete and the equipment, facilitating athletes at different distances to receive the ball and then pass it for training.

[0056] The above describes passing training where multiple athletes perform stationary passing drills in multiple directions. It also allows for dynamic passing training for a single athlete. In practice, the athlete receives the ball in one direction and passes it back. The athlete then runs to the next passing gap, receives the ball again, and passes it back, repeating this process. This allows the athlete to run around the circumference of the ball collection tray and perform passing drills in multiple directions, achieving dynamic passing training. This simulates the dynamic passing scenarios in a basketball game, training athletes to improve their passing skills. By throwing the ball in different directions and having the basketball player catch it while moving and then pass it back, this training method increases the frequency of passing and receiving, aiming to improve the athlete's reaction speed, spatial judgment, and passing accuracy, adapting to the dynamic scenarios of a game.
