Description

Technical Field

[0001] The present invention relates to the technical field of sports training auxiliary equipment, and in particular to a ball return device used in basketball training, and more particularly to a basketball ball return auxiliary device with adjustable return direction, which is suitable for collecting and guiding returned balls during basketball shooting training. Background Art

[0002] In basketball training, repeated shooting practice is crucial for improving shooting consistency and accuracy. Standing shooting (shooting from a fixed position) is a fundamental skill. Since the basketball must be retrieved after each shot, this places a significant burden on the trainer, often requiring dedicated personnel to retrieve and pass the ball. This increases training costs and difficulty. To address this issue, a variety of automated ball return devices have emerged on the market, designed to return the basketball to the athlete. However, existing automated ball return devices often have complex structures, are difficult to install, and lack flexibility in adjusting the return angle, making it difficult to achieve a precise return. To address these issues, prior art CN210009601U discloses a "360-degree fixed-point shooting return trainer." This device comprises a hanging frame, multiple hanging ears, a hanging rope, and a hook, with multiple sliding connectors (including left and right connectors) slidably connected to the hanging frame. The left connector has an I-shaped block at its lower end, while the lower ends of the multiple sliding connectors are connected to four ball return plates, which are interlocked and arranged in a grid pattern. Once assembled, a basketball dropped into the hoop will travel along the return plates to the trainer's position, achieving a 360-degree return.

[0003] Although the existing ball return device has solved the problem of ball return in training to a certain extent, it still has some shortcomings, including but not limited to: First, the return path control is not stable and precise enough. Existing devices generally rely on a fixed-shaped ball return surface for ball return, which makes the control of the ball return path relatively simple. In actual use, the ball may deviate from the predetermined direction due to factors such as impact angle, speed, or device vibration, making it difficult to maintain a precise and stable return path. The ball return path structure is a spliced ​​and snap-fit ​​type, consisting of four independent ball return pieces that snap together. This segmented structure is prone to component detachment or misalignment during use. Once a ball return piece detaches or becomes misaligned, the ball return path will be discontinuous, affecting return efficiency and training continuity.

[0004] Second, the lack of multi-dimensional adjustment capabilities prevents it from fully adapting to diverse training needs. The existing device's adjustment mechanism is limited to a sliding ball return plate. The existing ball returner can only adjust the ball return direction by moving the plate up and down using a left-right sliding connector. This limited adjustment range makes it difficult to tailor the return to different shooting angles, shooting distances, or specific training scenarios (such as free throws and three-pointers). The lack of a multi-axis linkage adjustment mechanism prevents flexible changes in the return direction and tilt angle. This makes it difficult for trainers to fine-tune the return angle based on specific needs, limiting the diversity and relevance of training.

[0005] Third, existing devices primarily rely on hook-type suspension. They use a rope and hook to secure the ball returner to the basket. This hook-type structure is dependent on the size and structure of the basket, resulting in poor adaptability and incompatibility with different basket models. Furthermore, this single suspension method makes the device unstable after installation, making it prone to shaking due to vibrations during training, thus compromising safety.

[0006] Fourth, the existing device's ball return path is non-closed. Because the ball returner is assembled using snap-on components, it lacks a closed ball return channel and a continuous guide track or anti-drop protection. If the ball encounters gaps in the joints or external interference during the return, it can easily deviate from the intended trajectory or fall off the return path, making the return reliable and safe. Summary of the Invention

[0007] In order to solve the above problems, the present invention provides a ball return device for basketball training, comprising: A detachable fixing mechanism is used to adapt the device to be installed on basketball hoops of different specifications or their auxiliary supporting structures, and provide multi-dimensional adjustment functions; A ball collecting guide component is provided below the basketball hoop and is configured to receive the basketball that falls after the shot and to collect the movement trajectory of the basketball through a convergent structure; A dynamic return component is connected to the ball collection guide component and includes at least one continuous streamlined path guide structure, which guides the basketball along a preset direction and automatically returns to the user area through gravity or inertia; A direction control component, integrated into the dynamic feedback component, is used to dynamically adjust the spatial orientation and feedback angle of the path guidance structure according to training requirements; Among them, the streamlined structure of the path guiding structure is combined with the multi-axis synergistic effect of the direction control component to ensure that the basketball maintains continuous movement without jamming during the return pass. The detachable fixing mechanism is compatible with various basketball hoop structures through a quick locking and height adaptation mechanism.

[0008] Preferably, the detachable fixing mechanism includes a rotary lock assembly, which includes a U-shaped clip and a rotating support. The clip groove at the inner end of the U-shaped clip is sleeved on the basketball hoop. Both ends of the U-shaped clip are provided with clearance holes, and the rotating support is connected to the clearance holes. The rotating support is a locking screw. The rotary lock connection mechanism is adopted, so that when the components are installed, they can be quickly positioned and locked by simply rotating and snapping them in. Compared with traditional bolt connections or sliding clips, the rotary lock structure is simple and easy to operate, and the locking is firm, which can effectively prevent loosening and falling off during use, thereby improving the reliability and installation efficiency of the overall device.

[0009] Preferably, the ball collecting guide component is a tapered flow guide cavity structure, comprising a plurality of angle adjustment rods, each of which is provided at one side end of the U-shaped clamp, a threaded limit groove being provided at the top end of the angle adjustment rod, the swivel support passing through the clearance hole and extending into the threaded limit groove, thereby locking the detachable fixing mechanism on the basketball hoop, the lower end of the angle adjustment rod being fixedly provided in the slot of the U-shaped sliding piece, the U-shaped sliding piece being fitted to the side end of the swivel positioning piece, another locking screw passing through the limit grooves on the U-shaped sliding piece and the swivel positioning piece, thereby fixing the U-shaped sliding piece to the swivel positioning piece, and the lower end of the swivel positioning piece being fixedly connected to a swivel ring. The tapered flow guide cavity is adopted, and its gradually closing design can effectively guide the basketball to move smoothly; at the same time, in conjunction with the angle adjustment rod, the inclination angle of the flow guide cavity can be adjusted as needed. This combined structure can control the rolling speed of the basketball and change the return direction, achieving more precise return control; regardless of the shooting strength, it can provide appropriate cushioning effect, thereby improving the controllability and stability of the return process.

[0010] Preferably, the path guidance structure includes a set of symmetrically arranged curved tracks, each of which is fixedly connected to a guide track at one end, thereby forming a closed track. A path guidance groove is formed between the curved track and the guide track. By combining the curved rotating track with the linear guide track, a completely closed return channel is constructed. This closed path ensures that the basketball will not fall off the track or fall during the return process, ensuring a continuous and reliable ball return process. Compared to open or discontinuous paths in the prior art, the closed return channel structure of the present invention significantly enhances the safety and stability of the ball return process.

[0011] Preferably, the direction control component includes a support connection unit fixedly arranged on the side end of the rotating ring, the other end of which is connected to the anti-slip rib structure, and the anti-slip rib structure is arranged at the center of the lower end of the rotating ring, and its two ends are respectively in contact with the arc track. A direction control component is provided, which has both guiding and supporting functions, wherein the support connection unit provides solid support for the return track, and the anti-slip rib structure effectively prevents the basketball from accidentally falling off the track when sliding at high speed. The cooperation of this component makes the return direction of the basketball more controllable and the running line more stable, which significantly improves the predictability and overall safety of the return ball.

[0012] Preferably, the support connection unit has a bent structure and includes a limit block fixedly mounted on the side of the hanging ring. The lower end of the limit block is fixedly connected to a support block, the end of the support block away from the limit block is fixedly connected to a bent bearing block, and the end of the bent bearing block away from the support block is fixedly connected to a locking frame. By designing a bent support connection structure for the corners of the return track, additional support and cushioning are provided at the bends. This structure smoothes the transition between track corners, reduces the impact and friction of the basketball at turns, and enhances the structural strength of curved sections, effectively improving the durability of the device during use.

[0013] Preferably, the anti-slip side structure includes a positioning connection block, which is provided at the upper end of the locking frame and fixedly connected thereto, and both ends of the positioning connection block are fixedly connected with a direction-regulating anti-slip baffle, and the direction-regulating anti-slip baffle includes a longitudinally arranged triangular baffle section, and the upper end of the triangular baffle section is fixedly provided with an obliquely extending square baffle section, and an anti-slip baffle is provided at the end of the return guide rail, and is tightly combined with the guide rail end structure to form a protective tail end. This design prevents the basketball from flying out or leaving the track due to inertia at the return end point, and ensures that the basketball is completely recovered and returns to the starting position. Compared with the possible escape of the return ball in the prior art, the anti-slip baffle structure of the present invention significantly improves the reliability of the equipment.

[0014] Preferably, a slotted clamp is fixed to the side of the triangular connecting section, away from the positioning and connecting block. This clamp is attached to the curved track, securing the return assembly. The clamp fits tightly with the track and bracket. Adjustable notches and bolts provide a rigid connection between components, preventing loosening or shifting after installation. Compared to conventional connectors, this slotted clamp ensures overall stability and precision of the connection, extending its service life.

[0015] Preferably, the inner walls of the triangular and square sections are each provided with an anti-rebound coating, preferably a silicone PU coating. The anti-rebound material applied to the return track effectively absorbs the rebound energy generated when the basketball contacts the track. This coating ensures a smoother roll and a more controllable return trajectory, suppressing random deviations. This significantly improves the accuracy and consistency of the return, meeting the high-quality return requirements during high-intensity training.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention uses a closed return track and a smooth guiding structure to enable the basketball to slide continuously and smoothly along a preset path. Compared with the return channels with openings or uneven corners in the prior art, the present invention achieves stable and continuous closure of the return path control. The basketball is always guided by the closed channel during the return process and will not deviate or fall off due to cross-section splicing, which greatly improves the continuity and reliability of the ball return process. In addition, it also reduces the deviation and jamming of the basketball, effectively avoiding the deviation and jamming of the basketball due to path inconsistency during the return process, ensuring the continuity and stability of the ball return, and thus significantly improving the continuity and safety of the training process.

[0017] This invention, introduced in a ball return mechanism, allows for flexible adjustment of the ball return direction and angle along multiple axes. Trainers can simultaneously adjust both the horizontal direction and vertical tilt of the ball return as needed, achieving precise returns from multiple angles and directions. This significantly increases training flexibility and diversity, meeting the needs of diverse training objectives.

[0018] The present invention incorporates a multi-degree-of-freedom linkage adjustment mechanism, an adjustable angle adjustment rod, and a rotating connector, enabling the return device's ball path angle and direction to be flexibly adjusted across multiple degrees of freedom. This allows for rapid changes in the return angle for shooting exercises at varying distances and directions, allowing trainers to simultaneously adjust the horizontal direction and vertical tilt of the return ball as needed. Compared to existing techniques, the present invention significantly enhances the diversity and adaptability of training, meeting the needs of diverse training scenarios. This allows for multi-dimensional adjustment of the return angle and direction to meet diverse training needs.

[0019] This invention improves the connection between the device and the basketball hoop, providing a more compatible and stable fixing solution. The device utilizes a detachable fixing mechanism compatible with various basketball hoop specifications, allowing the ball returner to be securely attached to various hoops, maintaining high stability during installation and use. This detachable fixing mechanism prevents shaking and loosening during training, improving overall installation reliability and the device's applicability.

[0020] This invention creates a closed, continuous ball-returning channel and incorporates an anti-drop mechanism on the direction-control assembly, ensuring the basketball remains on its intended trajectory throughout the return pass. This ensures the ball is fully restrained and guided throughout the return pass, effectively preventing drop or deviation caused by path interruptions, thereby improving the safety and efficiency of training.

DETAILED DESCRIPTION

[0026] The present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1-4 As shown, the present invention provides a ball return device for basketball training, comprising: A detachable fixing mechanism 1 is used to adapt the device to be installed on basketball hoops of different specifications or their auxiliary supporting structures, and provide multi-dimensional adjustment functions; The ball collecting guide component 2 is provided below the basketball hoop and is configured to receive the basketball that falls after the shot and to collect the movement trajectory of the basketball through a convergent structure; The dynamic return component 3 is connected to the ball collection guide component 2 and includes at least one continuous streamlined path guide structure 31, which guides the basketball along a preset direction and automatically returns to the user area through gravity or inertia; A direction control component 4 is integrated into the dynamic feedback component 3 and is used to dynamically adjust the spatial orientation and feedback angle of the path guidance structure 31 according to training requirements; Among them, the streamlined structure of the path guiding structure 31 is combined with the multi-axis synergistic effect of the direction control component 4 to achieve continuous movement of the basketball without jamming during the return pass. The detachable fixing mechanism 1 is compatible with various basketball hoop structures through a quick locking and height adaptation mechanism.

[0028] The detachable fixing mechanism 1 includes a rotating lock assembly 10, which includes a U-shaped clip 101 and a rotating support 102. The inner end of the U-shaped clip 101 has a clamping groove 103 that is inserted into the basketball hoop. Both ends of the U-shaped clip 101 have clearance holes 104, and the rotating support 102 is connected to the clearance holes 104. The rotating support 102 is a locking screw. The rotating lock assembly 10 is used to quickly fix the device. The clamping groove 103 of the U-shaped clip 101 is aligned with the edge of the basketball hoop and inserted into the clamping groove 103, so that the basketball hoop is embedded in the clamping groove 103. The locking screw of the rotating support 102 passes through the clearance holes 104 at both ends of the U-shaped clip 101 and screws into the threaded limit groove 202 at the top of the angle adjustment rod 201. The rotating support 102 is rotated clockwise until it is locked. At this time, the U-shaped clip 101 is tightly fitted to the basketball hoop, completing the initial fixation of the device.

[0029] The ball collecting guide component 2 is a tapered flow guide cavity structure, including multiple angle adjustment rods 201, the angle adjustment rod 201 is arranged on one side end of the U-shaped clamp 101, and a threaded limit groove 202 is opened on the top of the angle adjustment rod 201, and the rotating support 102 passes through the give way hole 104 and extends into the threaded limit groove 202, thereby locking the detachable fixing mechanism 1 on the basketball hoop, and the lower end of the angle adjustment rod 201 is fixedly set in the slot of the U-shaped sliding piece 203, and the U-shaped sliding piece 203 is fitted into the side end of the rotating positioning piece 204, and another locking screw passes through the U-shaped sliding piece 203 and the limiting groove on the rotating positioning piece 204 to fix the U-shaped sliding piece 203 and the rotating positioning piece 204, and the lower end of the rotating positioning piece 204 is fixedly connected with a rotating ring 205.

[0030] The tapered guide cavity structure guides the basketball's downward movement. The lower end of the angle adjustment rod 201 is inserted into the slot of the U-shaped sliding plate 203 and secured by another locking screw that passes through the limit slots of the U-shaped sliding plate 203 and the rotating positioning plate 204. The locking screw of the U-shaped sliding plate 203 is loosened; the U-shaped sliding plate 203 is slid along the rotating positioning plate 204 to change the inclination of the angle adjustment rod 201; the locking screw is tightened to fix the inclination of the guide cavity to accommodate different shooting forces and landing positions. The hanging ring 205 at the lower end of the rotating positioning plate 204 connects to the dynamic return component 3, forming a transition channel for the basketball from collection to return.

[0031] The path guide structure 31 includes a group of symmetrically arranged arc tracks 310, one end of each of which is fixedly connected to a guide track 311 to form a closed track. A path guide groove 312 is formed between the arc track 310 and the guide track 311. After the basketball falls into the path guide groove 312 through the ball collecting guide component 2, it slides smoothly along the streamlined track under the action of gravity to avoid getting stuck or derailing. By combining the arc-shaped rotary track with the straight guide track, a completely closed return channel is constructed. This closed path ensures that the basketball will not deviate from the track or fall during the return process, making the ball return process continuous and reliable. Compared with the open or discontinuous paths in the prior art, the closed return channel structure of the present invention significantly enhances the safety and stability of the ball return process.

[0032] The direction control component 4 includes a support and connection unit 40 fixedly arranged at the side end of the rotating ring 205. The support and connection unit 40 provides structural stability, and its other end is connected to the anti-slip rib structure 41. The anti-slip rib structure 41 ensures the safety of the return ball end point: the anti-slip rib structure 41 is arranged at the center of the lower end of the rotating ring 205, and its two ends are respectively abutted against the arc track 310. A direction control component 4 is provided, which has both guiding and supporting functions, wherein the support and connection unit provides solid support for the return track, and the anti-slip rib structure effectively prevents the basketball from accidentally falling off the track when sliding at high speed. The combination of this component makes the return direction of the basketball more controllable and the running line more stable, significantly improving the predictability and overall safety of the return ball.

[0033] The support connection unit 40 has a curved structure and includes a limit block 401 fixedly mounted on the side of the hanging ring 205. The lower end of the limit block 401 is fixedly connected to a support block 402. The end of the support block 402 away from the limit block 401 is fixedly connected to a bent support block 403. The end of the bent support block 403 away from the support block 402 is fixedly connected to a locking frame 404. By designing a curved support connection structure for the corners of the return track, additional support and cushioning are provided at the bends. This structure smoothes the track corner transition, reduces the impact and friction of the basketball at the turns, and enhances the structural strength of the curved sections, effectively improving the durability of the device during use.

[0034] The anti-slip edge structure 41 includes a positioning connection block 410, which is arranged at the upper end of the locking frame 404 and fixedly connected thereto, and both ends of the positioning connection block 410 are fixedly connected with a direction-regulating anti-slip baffle 411, and the direction-regulating anti-slip baffle 411 includes a longitudinally arranged triangular blocking section 412, and the upper end of the triangular blocking section 412 is fixedly provided with an obliquely extending square blocking section 413. By arranging an anti-slip baffle at the end of the return guide rail and closely combining it with the guide rail end structure, a protective tail end is formed. This design prevents the basketball from flying out or leaving the track due to inertia at the return end point, and ensures that the basketball is completely recovered to the starting position. Compared with the possible escape of the return ball in the prior art, the anti-slip baffle structure of the present invention significantly improves the reliability of the equipment.

[0035] A slotted clamp 414 is fixed to the side of the triangular connecting section 412, away from the positioning and connecting block 410. This clamp 414 is attached to the curved track 310, securing the return assembly. The clamp fits snugly with the track and bracket. Adjustable notches and bolts provide a rigid connection between components, preventing loosening or shifting after installation. Compared to conventional connectors, this slotted clamp ensures overall stability and precision, extending the service life of the device.

[0036] The inner walls of both triangular and square contact sections 412 and 413 are coated with an anti-rebound coating 415, preferably a silicone PU coating. This anti-rebound coating on the return track effectively absorbs the rebound energy generated when the basketball contacts the track. This coating ensures a smoother roll and a more controlled return trajectory, suppressing random deviations. This significantly improves the accuracy and consistency of the return, meeting the high-quality return requirements during high-intensity training.

[0037] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0038] The specific working process is as follows: during shooting training, after the basketball hits the basket, it passes through the basket and falls into the top opening of the ball collecting guide component 2 of the device. Under the action of gravity, the basketball slides downward along the tapered cavity formed by the angle adjustment rod 201 of the ball collecting guide component 2. After the basketball slides down from the rotating hanging ring 205 at the bottom of the ball collecting guide component 2, the basketball hits the silicon PU coated baffle of the anti-slip retaining structure 41 of the direction control component 4. After the energy is absorbed, it avoids obvious rebound. Under the action of the slope, the basketball rolls obliquely downward along the path guide groove formed by the curved track 310 and the guide track 311 of the path guide structure 31, rolls out in a controlled manner from the bottom of the device, and returns to the original position or designated position of the trainee. The entire return process is smooth and reliable, and the ball will not jump out or roll to an undesirable position. After the training is over, the fixing mechanism 1 can be quickly disassembled for easy storage and transportation.
