Abstract
Description
Technical Field
[0001] This invention belongs to the field of basketball training equipment, specifically a basketball launching device based on constant force spring and electromechanical power storage. Background Technology
[0002] In traditional basketball training, players usually rely on manual passes or repetitive shooting practice with a basket at a fixed height. This method has significant limitations: on the one hand, manual passing is limited by the physical strength and energy of coaches or training partners, making it difficult to ensure the continuity of high-intensity and high-frequency training; on the other hand, shooting practice in a fixed position cannot simulate the dynamic shooting scenarios of multiple angles and distances in actual games, which is not conducive to the comprehensive improvement of players' overall abilities.
[0003] With the advancement of sports technology, automated basketball launching devices are gradually becoming an important development direction for training aids. A search reveals that existing technologies for basketball launching devices include the following:
[0004] Patent application CN117065309A discloses a basketball training launcher, which includes: a mobile base; two lifting mechanisms, one on each side of the upper part of the mobile base; a bounce-through pass mechanism positioned above the right lifting mechanism; a high-lob pass mechanism positioned above the left lifting mechanism; and a basketball collecting mechanism located at the rear of the upper surface of the mobile base. This basketball training launcher can simulate serves at various heights and angles, allowing basketball players to simulate receiving passes from different angles during training, greatly improving their training effectiveness.
[0005] Patent application CN105749531A discloses a ball-launching machine for basketball dribbling training. The machine includes a base frame, a housing, a ball basket, a launch tube, and a ball-pushing seat. The housing is mounted on a crossbeam at the top of the base frame via a sliding seat, and the bottom of the housing is slidably connected to the crossbeam. The launch tube is housed within the housing, with its front opening hinged to the front wall of the housing, and its rear hinged to the upper end of a telescopic rod located at the bottom of the housing. The ball-pushing seat is located inside the launch tube, with its outer wall slidably connected to the inner wall of the launch tube, and has an open-front receiving cavity. The ball basket is located within the housing above the launch tube, fixed to the front wall of the housing, and its bottom is connected to the top front of the launch tube via a flexible tube. This invention features a simple structure, high automation, fast response speed, low manufacturing cost, and strong practicality. It can achieve passes from multiple angles, enriching training content.
[0006] Patent application CN112619091A discloses a basketball launcher for sports teaching with adjustable function. This patent application includes a movable base and a support frame. The movable base is equipped with a rotation control mechanism, and the support frame is mounted on the rotation control mechanism with one end hinged to it. The rotation control mechanism is equipped with an angle adjustment mechanism. This invention features a rotation control mechanism on a movable base, a support frame on the rotation control mechanism, a ball storage hopper on the upper part of the support frame, a launch tube inside the support frame, and a ball delivery pipe connecting the launch tube and the ball storage hopper. A pneumatic launching mechanism is installed inside the launch tube, and an angle adjustment mechanism is provided between the support frame and the rotation control mechanism. Through the combined action of the rotation control mechanism and the angle adjustment mechanism, comprehensive control of the launch angle is achieved, and the basketball is launched using the pneumatic launching mechanism.
[0007] While the aforementioned existing technologies have achieved automation and angle adjustment functions for basketball launching devices to a certain extent, they still have some significant limitations, specifically:
[0008] 1. Existing devices mostly use pneumatic or mechanical direct push methods. The adjustment of launch force, speed and angle relies on a rough structural design, which makes it difficult to achieve precise parameter control and cannot meet the fine requirements of specific shooting trajectories and forces in professional training.
[0009] 2. Some devices use disposable pneumatic energy storage, which results in uneven energy release, leading to poor consistency in the force and speed of each launch, affecting the continuity and reliability of training results.
[0010] 3. Adjusting the shooting angle of basketballs often relies on manual knobs and scale positioning. The process of adjusting the pitch angle is cumbersome, has limited accuracy, and it is difficult to achieve continuous and smooth angle changes, making it impossible to quickly adapt to the dynamic needs of different training scenarios. Summary of the Invention
[0011] The purpose of this invention is to provide a basketball launching device based on a constant force spring and electromechanical energy storage, so as to solve the problems of unstable energy release and poor angle adjustment accuracy during basketball launching in the prior art.
[0012] To achieve the above objectives, the present invention provides the following technical solution: a basketball launching device based on a constant force tension spring and electromechanical energy storage, wherein the basketball launching device is configured as an automatic launching device that achieves controllable launching of a basketball through energy storage and electromechanical drive, the automatic launching device including a pitching mechanism and a launching mechanism, wherein:
[0013] The pitch mechanism includes a base frame, a front support arm, a rear support arm, a fixed frame, and an adjustment assembly. The base frame is supported on a plane, and inner hinge seats and outer hinge seats are respectively provided at the front and rear ends of the base frame. The front support arm and the rear support arm are hinged to the inner hinge seats and the outer hinge seats respectively. The free end of the front support arm is connected to the tail of the launching mechanism. The adjustment assembly includes a support member, a first drive member, a lead screw, and a pitch adjustment plate. The first drive member is installed at the rear end of the support member, and the shaft end of the first drive member is connected to a lead screw. The lead screw is connected to the front end of the support member through a bearing, and a nut seat is provided on the lead screw. The lower end of the pitch adjustment plate is hinged to the free end of the rear support arm, and the nut seat is connected to the middle of the upper end of the pitch adjustment plate.
[0014] The launching mechanism includes a launching guide frame, a timing belt assembly, an energy storage component, a ball pusher, a linkage locking component, and a deceleration component. The launching guide frame has reinforcing ribs spaced apart on its bottom side and a guide rail on its inner side. The timing belt assembly is mounted on the launching guide frame and includes a second driving component, an upper pulley, a lower pulley, and a timing belt. The upper pulley and lower pulley are located at the beginning and end of the launching guide frame, and the lower pulley shaft is connected to the second driving component, the lower pulley, and the upper pulley via a timing belt.
[0015] Preferably, the support member is a support frame with reinforcing ribs on the upper side and guide rails on the lower side, and the upper sides of the pitch adjustment plate are provided with linear rail seats that are slidably connected to the upper guide rails of the support member.
[0016] Preferably, the upper end of the support member is connected to the middle and top of the launching mechanism through a fixing frame, and the rear end of the support member extends towards the front support arm to form a cantilever support structure. This cantilever support structure is connected to the tail of the launching mechanism, forming a multi-point connection layout. This multi-point connection method makes the connection between the launching mechanism and the pitching mechanism more stable and can withstand various forces generated during the basketball launch process, including the impact force during launch and the pulling force when the ball pusher moves, preventing the launching mechanism from shaking or shifting during operation and ensuring the stability of the launching mechanism.
[0017] Preferably, the energy storage component is a constant-force tension spring, which is located at the front end of the launch guide frame. The free end of the constant-force tension spring is connected to the ball-pushing frame by bolts. The constant-force tension spring provides a nearly constant tension throughout the entire stretching process. When the linkage locking component moves the ball-pushing frame backward via the locking hook, the constant-force tension spring is gradually stretched and stores energy. Its constant tension ensures the stability of the energy storage process, preventing uneven energy release as seen in traditional pneumatic or disposable energy storage devices. This ensures that the energy stored in the constant-force tension spring is essentially consistent each time it stretches the same distance, providing a stable power foundation for subsequent basketball launches.
[0018] Preferably, the ball-pushing frame and the linkage locking component are both slidably connected to the guide rail inside the launch guide frame via a sliding block. The guide rail provides a precise movement path for the ball-pushing frame and the linkage locking component. During the process of the synchronous belt assembly driving the linkage locking component to move, thereby driving the ball-pushing frame to move backward to store power and then releasing the ball-pushing frame to launch the basketball forward, the ball-pushing frame can move smoothly in a straight line along the guide rail. The ball-pushing frame is located in front of the linkage locking component and is equipped with a cross-shaped support part for carrying the basketball.
[0019] Preferably, a collision protection plate is provided on the outside of the ball pusher. The collision protection plate is arranged around the outside of the ball pusher so that it can make priority contact with external objects when a collision occurs, preventing the impact force from being directly transmitted to the load-bearing part, causing the basketball to shift, fall off, or deviate from the launch trajectory; a tail hook is provided on the rear side of the ball pusher.
[0020] Preferably, the inner side of the linkage locking component is connected to the synchronous belt, and the linkage locking component is provided with a locking hook that cooperates with the tail hook. The locking hook is driven by the third driving component. The linkage locking component moves synchronously with the synchronous belt and locks the ball pusher frame through the locking hook. Then, it drives the ball pusher frame to move backward, causing the constant force tension spring to stretch and store energy.
[0021] Power Accumulation Phase: Driven by the synchronous belt assembly, the linkage locking component moves synchronously to the preset position along with the synchronous belt. At this time, the third drive component drives the locking hook to precisely engage with the tail hook on the rear side of the ball pusher, reliably locking and fixing the ball pusher. Subsequently, the linkage locking component continues to drive the locked ball pusher to move backward, causing the constant force spring to gradually stretch and store energy, thus reserving stable power for the launch phase.
[0022] Launch phase: After the constant force tension spring has stored energy, the third drive component drives the locking hook to release the tail hook, and the ball pusher and the linkage locking component are unlocked; the ball pusher is launched forward instantly under the restoring force of the constant force tension spring, realizing precise and controllable kinetic energy transfer.
[0023] Preferably, the launching guide frame also has a deceleration component at its front end for slowing down the ball-pushing frame after launch. This deceleration component is a deceleration rubber band. The deceleration rubber band has good elasticity. When the ball-pushing frame moves forward at high speed due to the energy released by the constant force spring, the deceleration rubber band can contact the ball-pushing frame and apply a reverse elastic force to it. This elastic force gradually increases, causing the speed of the ball-pushing frame to gradually decrease, avoiding violent impact and vibration caused by the ball-pushing frame stopping suddenly, and achieving smooth deceleration of the ball-pushing frame.
[0024] Compared with existing technologies, the present invention has the following beneficial effects: By coordinating a constant force spring and electromechanical energy storage, the present invention utilizes a synchronous belt assembly, a linkage locking component, a locking hook, and other components to drive the ball-pushing frame backward. The constant force spring stores energy during tension and provides stable power upon release, further achieving stable energy release during basketball launch and precise controllable adjustment of the launch angle. Specific technical effects include the following:
[0025] 1. Using a constant force spring as the energy storage element, compared with the existing pneumatic or mechanical direct pushing method, it can provide a stable and uniform launching force, avoiding the problem of inconsistent launching force and speed caused by uneven release of pneumatic energy storage in traditional devices. It can precisely control the launching force of the basketball; the tension of the constant force spring is adjusted by precisely controlling the backward movement distance of the ball pusher through the electromechanical drive synchronous belt assembly, thereby accurately controlling the launching speed.
[0026] 2. The adjustment component in the pitch mechanism uses a first driving element to drive the lead screw to rotate, which in turn moves the nut seat and the pitch adjustment plate, achieving precise adjustment of the launch mechanism's pitch angle. Compared to the manual knob and scale positioning methods of some existing devices, this adjustment process is much simpler. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0036] As attached Figure 1 To be continued Figure 3 As shown:
[0037] Example 1: This invention provides a basketball launching device based on a constant force spring and electromechanical energy storage. The basketball launching device is configured as an automatic launching device that achieves controllable launching of a basketball through energy storage and electromechanical drive. The automatic launching device includes a launching mechanism, which includes a launching guide frame 10, a synchronous belt assembly 11, an energy storage component 12, a ball pusher 13, a linkage locking component 14, and a deceleration component 15. The launching guide frame 10 has reinforcing ribs spaced apart on its bottom side, and a guide rail is provided on the inner side of the launching guide frame 10. The synchronous belt assembly 11 is mounted on the launching guide frame 10 and includes a second driving component (synchronous belt motor), an upper pulley, a lower pulley, and a synchronous belt. The upper pulley and the lower pulley are located at the beginning and end of the launching guide frame 10, and the lower pulley shaft is connected to the second driving component, the lower pulley, and the upper pulley through the synchronous belt linkage.
[0038] 1. In one embodiment of the present invention, the energy storage component 12 is a constant-force tension spring, which is located at the head end of the launch guide frame 10. The free end of the constant-force tension spring is connected to the ball-pushing frame 13 by bolts. The constant-force tension spring can provide an approximately constant tension throughout the stretching process. When the linkage locking component 14 drives the ball-pushing frame 13 to move backward through the locking hook 17, the constant-force tension spring is gradually stretched and stores energy. Its constant tension ensures the stability of the energy storage process and avoids the uneven energy release that occurs with traditional pneumatic or disposable energy storage devices. This ensures that the energy stored in the constant-force tension spring is basically consistent each time it stretches the same distance, providing a stable power foundation for subsequent basketball launches.
[0039] 2. In one embodiment of the present invention, the ball-pushing frame 13 and the linkage locking member 14 are both slidably connected to the guide rail inside the launch guide frame 10 via a sliding seat. The guide rail provides a precise movement path for the ball-pushing frame 13 and the linkage locking member 14. During the process of the synchronous belt assembly 11 driving the linkage locking member 14 to move, thereby driving the ball-pushing frame 13 to move backward to store power and release the ball-pushing frame 13 to launch the basketball forward, the ball-pushing frame 13 can move smoothly in a straight line along the guide rail. The ball-pushing frame 13 is located in front of the linkage locking member 14, and the ball-pushing frame 13 is provided with a cross-shaped bearing part for carrying the basketball.
[0040] 3. In one embodiment of the present invention, a collision protection plate is provided on the outer side of the ball pusher 13, and a tail hook 16 is provided on the rear side of the ball pusher 13.
[0041] 4. In one embodiment of the present invention, the inner side of the linkage locking member 14 is connected to the synchronous belt, and the linkage locking member 14 is provided with a locking hook 17 that cooperates with the tail hook 16. The locking hook 17 is driven by the third driving member 18 (servo motor or drive motor). The linkage locking member 14 moves synchronously with the synchronous belt and locks the pusher frame 13 through the locking hook 17. Then, it drives the pusher frame 13 to move backward so that the constant force tension spring is stretched and stores energy.
[0042] 5. In one embodiment of the present invention, the launching guide frame 10 is further provided with a deceleration member 15 for slowing down the ball-pushing frame 13 after launch. The deceleration member 15 is a deceleration rubber band. The deceleration rubber band has good elasticity. When the ball-pushing frame 13 moves forward at high speed due to the energy released by the constant force spring, the deceleration rubber band can contact the ball-pushing frame 13 and apply a reverse elastic force to it. This elastic force gradually increases, causing the speed of the ball-pushing frame 13 to gradually decrease, avoiding the violent impact and vibration caused by the sudden stop of the ball-pushing frame 13, and realizing the smooth deceleration of the ball-pushing frame 13.
[0043] Working principle: In embodiment one, the second drive member of the synchronous belt assembly 11 drives the lower pulley to rotate, and the upper pulley is linked by the synchronous belt, so that the linkage locking member 14 mounted on the synchronous belt moves synchronously with the synchronous belt; under the drive of the third drive member 18, the linkage locking member 14 locks the ball pusher 13 through the locking hook 17, and drives the ball pusher 13 to move backward along the guide rail inside the launch guide frame 10, so that the constant force tension spring located at the head end of the launch guide frame 10 is gradually stretched and stores energy. The constant force tension spring provides approximately constant energy throughout the stretching process. The tension ensures the stability of the energy storage process; when the launch conditions are reached, the locking hook 17 unlocks, the constant force spring releases energy, and pushes the ball pusher 13 to move forward at high speed along the guide rail. The cross-shaped bearing part on the ball pusher 13 carries the basketball and launches it; after the ball pusher 13 is launched, the deceleration rubber band at the head of the launch guide frame 10 contacts the ball pusher 13 and applies a reverse elastic force to it, so that the speed of the ball pusher 13 gradually decreases, achieving smooth deceleration. The entire process achieves controllable launch of the basketball through energy storage and electromechanical drive.
[0044] It is important to note that the constant force spring, as the core energy storage element, directly affects the amount of energy stored. In practice, the release force of the basketball can be adjusted by changing the extension length of the constant force spring. Specifically, during the charging phase, the energy value stored in the constant force spring can be precisely changed by controlling the distance the linkage locking component 14 moves backward, which drives the ball-pushing frame 13 (i.e., the extension of the constant force spring). The greater the extension length, the greater the restoring force provided when the constant force spring is released, and the stronger the basketball release force; conversely, the force is weakened. This adjustment method is simple and reliable, and can flexibly adapt to the refined requirements of shooting distance and trajectory in different training scenarios.
[0045] As attached Figure 4 To be continued Figure 5As shown:
[0046] Example 2: This example is basically the same as the previous example, except that the automatic launching device also includes a pitch mechanism. The pitch mechanism is used to support the launching mechanism in Example 1 and provide angle adjustment function, further realizing the flexible controllability of the basketball launching angle, the adaptability of multi-scenario simulation training, and the professional improvement of training effect. The pitch mechanism includes a base frame 1, a front support arm 2, a rear support arm 3, a fixed frame 4, and an adjustment component. The base frame 1 is supported on a plane. The front and rear ends of the base frame 1 are respectively provided with an inner hinge seat and an outer hinge seat. The front support arm 2 and the rear support arm 3 are respectively hinged to the inner hinge seat and the outer hinge seat. The free end of the front support arm 2 is connected to the tail of the launching mechanism. The adjustment component includes a support member 5, a first drive member 6 (drive motor), a lead screw 7, and a pitch adjustment plate 8. The first drive member 6 is installed at the rear end of the support member 5. The shaft end of the first drive member 6 is connected to the lead screw 7. The lead screw 7 is connected to the front end of the support member 5 through a bearing. A nut seat is provided on the lead screw 7.
[0047] 1. In one embodiment of the present invention, the support member 5 is a support frame with reinforcing ribs on the upper side and guide rails on the lower side. The upper sides of the pitch adjustment plate 8 are provided with linear rail seats 9 that are slidably connected to the guide rails on the support member 5. The lower end of the pitch adjustment plate 8 is hinged to the free end of the rear support arm 3. The middle of the upper end of the pitch adjustment plate 8 is connected to a nut seat.
[0048] 2. In one embodiment of the present invention, the upper end of the support member 5 is connected to the middle and top of the launching mechanism through the fixing frame 4. The rear end of the support member 5 extends towards the front support arm 2 to form a cantilever support structure. The cantilever support structure is connected to the tail of the launching mechanism, forming a multi-point connection layout. This multi-point connection method can withstand various forces generated during the basketball launching process, including the impact force during launching and the pulling force when the ball pusher 13 moves, etc., to prevent the launching mechanism from shaking or shifting during operation and to ensure the stability of the launching mechanism.
[0049] Working principle: In embodiment two, the first driving component 6 drives the lead screw 7 to rotate. Since the lead screw 7 is connected to the support component 5 through a bearing and a nut seat is provided on it, the rotation of the lead screw 7 will drive the nut seat to move along the axial direction of the lead screw 7. The nut seat is also connected to the middle of the upper end of the pitch adjustment plate 8. The linear rail seats 9 on both sides of the upper end of the pitch adjustment plate 8 are slidably connected to the guide rails on the support component 5, so that the movement of the nut seat can drive the movement of the pitch adjustment plate 8. Since the lower end of the pitch adjustment plate 8 is hinged to the free end of the rear support arm 3, when the pitch adjustment plate 8 moves, the entire launch mechanism will use the hinge point as the fulcrum to realize the flexible adjustment of its angle, meet the needs of multi-scenario simulation training and improve the professionalism of training effect.
[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
