Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and in particular to a single-person basketball training assistance device. Background Art

[0002] In basketball training, the traditional training mode mainly relies on manual coaches. This method requires a large amount of human resources and may be affected by the coach's or the assistant's own state, skills, and experience, resulting in unstable training effects. With the rapid development of robot technology, its applications in various fields are becoming increasingly widespread. In sports training, robots have gradually been introduced into some projects to improve training effects and efficiency. Basketball is a sport that requires high skills, speed, and judgment, and a large amount of human input is needed during the training process. For basketball training, the introduction of robot technology can break through the limitations of the traditional training mode and provide more scientific and systematic training for athletes. Currently, the research on basketball ball throwers in the market is relatively scarce, and most ball throwers are mainly applicable to small balls (such as badminton, table tennis, tennis, etc.). The research on ball throwers for medium and large balls such as basketball is very limited. With the popularization and development of basketball, the demand for basketball training is also increasing continuously. The traditional training methods can no longer meet the needs of athletes and coaches, and they hope to have a more efficient and intelligent training method to improve training effects. With the rapid development of robot technology, more and more fields are applying robot technology to improve work efficiency and reduce costs. Introducing robot technology into sports training has become a trend.

[0044] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0045] It should be noted that like reference numerals and letters refer to like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] Referring to Figures 1 - 10 , a single-person basketball training assistance device, comprising:

[0047] a chassis mechanism for supporting and moving the ball collection mechanism 4 and the ball launching mechanism 5;

[0048] The chassis mechanism includes a support plate 1, a rear-wheel moving assembly 2 and a front-wheel moving assembly 3. A rear-wheel moving assembly 2 is installed on one side of the support plate 1, and a front-wheel moving assembly 3 is installed on the other side of the support plate 1, so that the support plate 1 can be moved through the cooperation of the rear-wheel moving assembly 2 and the front-wheel moving assembly 3, and turning or steering can be achieved through the operation of the rear-wheel moving assembly 2;

[0049] The rear-wheel moving assembly 2 includes universal wheels 6, first belt pulleys 7, a rear-wheel drive motor 8 and second belt pulleys 9. Universal wheels 6 are rotatably connected to both ends of the bottom of one side of the support plate 1, so that the universal wheels 6 can rotate at the bottom of the support plate 1 to achieve the steering of the device. The top of the universal wheel 6 penetrates through the support plate 1 and is fixed with a first belt pulley 7, so that the rotation of the first belt pulley 7 can drive the universal wheel 6 to rotate synchronously. A rear-wheel drive motor 8 is fixed on the top of the support plate 1. The output end of the rear-wheel drive motor 8 is connected with a second belt pulley 9. The second belt pulley 9 is connected with the first belt pulley 7 through a synchronous belt. Furthermore, the rotation of the second belt pulley 9 can drive the two first belt pulleys 7 to rotate synchronously through the rear-wheel drive motor 8, so that the two first belt pulleys 7 drive the two universal wheels 6 to rotate in the same rotation direction;

[0050] The front-wheel moving assembly 3 includes front rotating wheels 10, power shafts 11, front-wheel drive motors 12, displacement driving gears 13, displacement driven gears 14, first bevel gears 15, second bevel gears 16, limiting plates 17, third bevel gears 18 and fourth bevel gears 19. Power shafts 11 are rotatably connected to the inside of both ends of the other side of the support plate 1, so that the power shafts 11 can rotate inside the other side of the support plate 1 through bearings. Front rotating wheels 10 are fixed to the mutually remote ends of the two power shafts 11, so that the rotation of the power shafts 11 drives the front rotating wheels 10 to rotate synchronously. A second bevel gear 16 is connected to the outside of one of the power shafts 11 by a flat key, so that the rotation of the second bevel gear 16 drives one of the power shafts 11 to rotate synchronously;

[0051] A front-wheel drive motor 12 is fixed to the top of the support plate 1. The output end of the front-wheel drive motor 12 is connected to a displacement driving gear 13. One end of the displacement driving gear 13 is meshed and connected to a displacement driven gear 14. The displacement driven gear 14 is rotatably connected to the support plate 1, so that the rotation of the displacement driving gear 13 drives the displacement driven gear 14 to rotate. A first bevel gear 15 is fixed to one side of the displacement driven gear 14. The first bevel gear 15 is meshed and connected to a second bevel gear 16, and the diameter of the first bevel gear 15 is smaller than that of the second bevel gear 16. Thus, the rotation of the first bevel gear 15 can drive the second bevel gear 16 to rotate at a reduced speed. Both sides of one end of the second bevel gear 16 are fixed with limit plates 17. A third bevel gear 18 is rotatably connected to the adjacent side of the two limit plates 17. Both ends between the two adjacent third bevel gears 18 are meshed and connected to a fourth bevel gear 19. The fourth bevel gear 19 is fixed to the power shaft 11. So, the rotation of one of the power shafts 11, through the cooperation of one of the fourth bevel gears 19 and the two third bevel gears 18, drives the rotation of the other fourth bevel gear 19, and makes the other fourth bevel gear 19 drive the other power shaft 11 to rotate, so that the two power shafts 11 both drive the front rotating wheels 10 to rotate in the same direction, and then the device can move forward and backward;

[0052] The ball collection mechanism 4 is installed at both ends of the chassis mechanism and is used for grasping the basketballs on the ground;

[0053] The ball collection mechanism 4 includes an angle adjustment component and a grasping component. The grasping component is located at one end of the angle adjustment component. The angle adjustment component is used to adjust the angle of the grasping component, and the grasping component is used to clamp or release the basketball;

[0054] The angle adjustment component includes a planar rotation motor, a chassis 20, a first adjustment frame 21, a first angle adjustment driving motor 22, a second adjustment frame 23, a second angle adjustment driving motor 24, a first angle gear 25, a second angle gear 26 and a connecting shaft 27. The bottom of the planar rotation motor is bolted to the support plate 1. The output end of the planar rotation motor is connected to the chassis 20, so that the planar rotation motor can be installed at both ends of the support plate 1, and the operation of the planar rotation motor drives the planar rotation of the chassis 20. Both ends of the top of the chassis 20 are rotatably connected to the first adjustment frame 21. The two first adjustment frames 21 can be fixed by bolts to realize the synchronous rotation of the two first adjustment frames 21. The first angle adjustment driving motor 22 is fixed to the top of the chassis 20. The output end of the first angle adjustment driving motor 22 is connected to the first adjustment frame 21, so that the operation of the first angle adjustment driving motor 22 drives the first adjustment frame 21 to rotate;

[0055] One end of the first adjusting frame 21 away from the chassis 20 is rotatably connected to a connecting shaft 27. On the outer side of the connecting shaft 27 and at both ends of the first adjusting frame 21, second adjusting frames 23 are bolted and fixed, so that the rotation of the connecting shaft 27 can drive the second adjusting frame 23 to rotate, and thus the angle between the second adjusting frame 23 and the first adjusting frame 21 can be adjusted; a second angle gear 26 is fixed on the outer side of the connecting shaft 27 and between the two second adjusting frames 23. One end of the first adjusting frame 21 is fixed with a second angle adjusting driving motor 24. The output end of the second angle adjusting driving motor 24 and between the two first adjusting frames 21 is connected with a first angle gear 25. The first angle gear 25 is meshed and connected with the second angle gear 26, so that the rotation of the first angle gear 25 can drive the engaged second angle gear 26 to drive the connecting shaft 27 to rotate, and the connecting shaft 27 drives the second adjusting frame 23 to rotate at one end of the first adjusting frame 21. The diameter of the first angle gear 25 is smaller than the diameter of the second angle gear 26, and thus the first angle gear 25 can drive the second angle gear 26 to rotate at a reduced speed;

[0056] The grasping assembly includes a transmission shaft 28, a clamping driving motor 29, a fixing frame 30, clamping claws 31, a threaded column 32, a displacement frame 33 and a connecting rod 34. A transmission shaft 28 is rotatably connected between the two second adjusting frames 23 and at one end away from the first adjusting frame 21, so that the transmission shaft 28 can only rotate between the two second adjusting frames 23, but the transmission shaft 28 cannot be separated from the second adjusting frames 23. A clamping driving motor 29 is fixed between the two second adjusting frames 23. The output end of the clamping driving motor 29 is connected to the transmission shaft 28, so that the operation of the clamping driving motor 29 drives the transmission shaft 28 to rotate. A threaded column 32 is fixed at the end of the transmission shaft 28 away from the clamping driving motor 29. A fixing frame 30 is rotatably connected to the outer side of the transmission shaft 28 near the threaded column 32. A displacement frame 33 is threadedly connected to the outer side of the threaded column 32. Clamping claws 31 are evenly rotatably connected to the outer side of the fixing frame 30, and the shape of the clamping claws 31 is curved or arc-shaped or multi-folded plate-shaped, and thus multiple clamping claws 31 can approach to grasp the basketball and loosen the basketball by moving away from each other. A connecting rod 34 is rotatably connected to the outer side of the displacement frame 33 and at a position corresponding to the clamping claws 31. The connecting rod 34 is rotatably connected to the clamping claws 31, so that the movement of the displacement frame 33 opens the multiple clamping claws 31 through the connecting rod 34;

[0057] Preferably, rotation stopping rods 59 are fixed to the top and bottom of one end of the fixing frame 30 close to the second adjusting frame 23. The rotation stopping rods 59 are bolted and fixed to the second adjusting frame 23, so that the rotation stopping rods 59 fixed between the fixing frame 30 and the second adjusting frame 23 prevent the fixing frame 30 from rotating due to friction when the transmission shaft 28 rotates.

[0058] The ball launching mechanism 5 is installed on the top of the chassis mechanism and is used to launch the basketballs recycled by the ball collecting mechanism 4.

[0059] The ball launching mechanism 5 includes an adjusting mechanism 35, two limiting mechanisms 36, a projecting mechanism 37 and a placing mechanism 38. The adjusting mechanism 35 is located on one side of the projecting mechanism 37, and the placing mechanism 38 is located on the side of the projecting mechanism 37 away from the adjusting mechanism 35. The basketballs are placed and projected through the placing mechanism 38. The limiting mechanisms 36 are located at both ends of the adjusting mechanism 35, so that the rotation angle of the projecting mechanism 37 driven by the adjusting mechanism 35 can be restricted by the limiting mechanisms 36.

[0060] The adjusting mechanism 35 includes a rotating shaft 39, a chassis 40, a rotating rod 41, a rotation adjusting drive motor 56, a first rotating bevel gear 57 and a second rotating bevel gear 58. The outer sides of both ends of the rotating shaft 39 are rotatably connected to the chassis 40. The bottom of the chassis 40 is bolted to the support plate 1, so that the position of the rotating shaft 39 can be limited by the chassis 40. A rotating rod 41 is fixed to the outer side of the rotating shaft 39 and inside the chassis 40, so that the rotation of the rotating shaft 39 can drive the rotating rod 41 to rotate synchronously. The rotation adjusting drive motor 56 is fixed to the top of the support plate 1. The output end of the rotation adjusting drive motor 56 is connected to the first rotating bevel gear 57. One side of the first rotating bevel gear 57 is meshed with the second rotating bevel gear 58. The inner side of the second rotating bevel gear 58 is fixed to the rotating shaft 39, so that the rotation of the first rotating bevel gear 57 drives the rotating shaft 39 to rotate through the meshed second rotating bevel gear 58.

[0061] Each limiting mechanism 36 includes a sliding block 42, an arc plate 43 and a travel bolt 44. The shape of the arc plate 43 is semi-circular. The bottoms of both sides of the arc plate 43 are bolted to the support plate 1. A sliding block 42 is slidably connected to the top of the arc plate 43. The sliding block 42 is slidably connected to the rotating rod 41, so that the position of the sliding block 42 can be adjusted on the outer side of the rotating rod 41 and fixed by bolts after adjustment, so that the sliding block 42 can only slide on the outer side of the arc plate 43. Travel bolts 44 are arranged inside both sides of the arc plate 43, so as to limit the rotation travel of the sliding block 42 on the outer side of the arc plate 43 through the two travel bolts 44.

[0062] The projection mechanism 37 includes a fixed housing 46, a projection drive motor 47, a first projection bevel gear 48, a second projection bevel gear 49, and a projection shaft 50. One end of the two rotating rods 41 away from the chassis 40 is bolted and fixed with the fixed housing 46. The projection drive motor 47 is fixed inside the fixed housing 46. The output end of the projection drive motor 47 is connected with the first projection bevel gear 48. One side of the first projection bevel gear 48 is meshed and connected with the second projection bevel gear 49. The diameter of the second projection bevel gear 49 is larger than that of the first projection bevel gear 48, so that the rotation of the first projection bevel gear 48 drives the second projection bevel gear 49 to rotate at a reduced speed. The projection shaft 50 is fixed inside the second projection bevel gear 49, and the projection shaft 50 is rotatably connected with the fixed housing 46;

[0063] The placement mechanism 38 includes a synchronous rod 51, a rotating pulley 53, a placement frame 54, and a guide sleeve 55. The adjacent ends of the two rotating rods 41 and on the side away from the chassis 40 are both provided with synchronous rods 51, and the distance between the two synchronous rods 51 is smaller than the diameter of the basketball. One end of each of the two synchronous rods 51 is rotatably connected with the rotating rod 41 through the rotating pulley 53, so that the rotation of the rotating pulley 53 can drive the two synchronous rods 51 to rotate between the two rotating rods 41, thereby adjusting the angle between the synchronous rod 51 and the rotating rod 41. The rotating pulley 53 is connected with the projection shaft 50 through a synchronous belt, so that the rotation of the projection shaft 50 drives the rotating pulley 53 to rotate through the synchronous belt. Let the rotating pulley 53 drive the synchronous rod 51 to rotate. One end of the two synchronous rods 51 away from the rotating rod 41 is fixed with a placement frame 54. The shape of the placement frame 54 is rectangular, so that the basketball can be stored through the placement frame 54. One end of the placement frame 54 close to the rotating rod 41 and outside the synchronous rod 51 is fixed with a guide sleeve 55, so that the basketballs on the tops of the two synchronous rods 51 can enter the inside of the placement frame 54 through the guide sleeve 55;

[0064] Preferably, a limit frame 45 is bolted and fixed at the top of the two rotating rods 41 and at the end of the fixed housing 46 away from the chassis 40. A limit pin 52 is bolted and fixed inside one end of the synchronous rod 51 close to the rotating pulley 53, so that the rotation angle of the synchronous rod 51 at one end of the rotating rod 41 can be limited through the cooperation of the limit pin 52 and the limit frame 45.

[0065] In this embodiment, it further includes a collection device composed of a semi-circular net surrounding the basketball court.

[0066] The drive member in this embodiment can be at least one of a stepper motor, a DC servo motor, an AC servo motor, and a hydraulic servo motor in other embodiments.

[0068] The synchronous belt in this embodiment can be selected as a synchronous flat belt or a synchronous toothed belt according to its function in actual application.

[0069] The usage process of a single-person basketball training assistance device provided by the present invention is as follows:

[0070] When in use, first, according to the position of the basketball, the operation of the front-wheel drive motor 12 drives the displacement driving gear 13 to drive the displacement driven gear 14 to rotate. The rotation of the displacement driven gear 14 drives the meshed second bevel gear 16 to rotate through the first bevel gear 15, so that the rotation of the second bevel gear 16 drives one of the power shafts 11 to rotate. The rotation of one of the power shafts 11 drives one of the fourth bevel gears 19 to rotate. The rotation of one of the fourth bevel gears 19 drives the other fourth bevel gear 19 to rotate through the meshed third bevel gear 18, so that the other fourth bevel gear 19 drives the other power shaft 11 to rotate. The rotation of the two power shafts 11 drives the two front rotating wheels 10 to rotate in the same direction, and with the assistance of the universal wheels 6, the support plate 1 moves. When turning, the operation of the rear-wheel drive motor 8 drives the second pulley 9 to rotate. The rotation of the second pulley 9 drives the first pulley 7 to rotate through the synchronous belt, so that the rotation of the first pulley 7 drives the universal wheels 6 to rotate, and thus the device can turn;

[0071] When the device is near the basketball, at this time, the operation of the first angle adjustment drive motor 22 drives the first adjustment frame 21 to rotate on the top of the chassis 20, and the operation of the second angle adjustment drive motor 24 drives the first angle gear 25 to drive the meshed second angle gear 26 to rotate. The rotation of the second angle gear 26 drives the second adjustment frame 23 to rotate at one end of the first adjustment frame 21 through the connecting shaft 27, and thus the position of the fixed frame 30 can be adjusted at multiple angles. Then, the operation of the clamping drive motor 29 drives the transmission shaft 28 to rotate. The rotation of the transmission shaft 28 drives the threaded column 32 to rotate, so that the rotation of the threaded column 32 drives the displacement frame 33 connected by threads to move. The movement of the displacement frame 33 adjusts the clamping claws 31 through the connecting rod 34, and the clamping claws 31 rotate with one end connected to the fixed frame 30 as the center, and thus the multiple clamping claws 31 can approach to grab the basketball. Then, the operation of the planar rotation motor drives the rotation of the chassis 20, so that the grabbed basketball is located on the top of the placement mechanism 38;

[0072] At this time, one adjacent end between the placing mechanism 38 and the projecting mechanism 37 is in an upper position, and the mutually distant ends between the placing mechanism 38 and the projecting mechanism 37 are in a lower position, so that the plurality of clamping claws 31 are away from the basketball that may slide out, and enter the inner side of the placing frame 54 through the support of the two synchronizing rods 51 and the guiding of the guiding sleeve 55. Then, the operation of the projecting driving motor 47 drives the first projecting bevel gear 48 to rotate, and the rotation of the first projecting bevel gear 48 drives the projecting shaft 50 to rotate through the meshing connection with the second projecting bevel gear 49. The projecting shaft 50 drives the rotating belt pulley 53 to rotate through the synchronous belt, so that the rotating belt pulley 53 drives the two synchronizing rods 51 to rotate between the two rotating rods 41, thereby adjusting the included angle between the rotating rod 41 and the synchronizing rod 51, and limiting the minimum included angle through the cooperation of the limit pin 52 and the limit frame 45;

[0073] After the adjustment is completed, the operation of the rotation adjustment driving motor 56 drives the first rotation bevel gear 57 to rotate, and the rotation of the first rotation bevel gear 57 drives the second rotation bevel gear 58 engaged therewith to drive the rotating shaft 39 to rotate, so that the rotation of the rotating shaft 39 drives the rotating rod 41 to rotate synchronously, and the rotation of the rotating rod 41 drives the synchronizing rod 51 to drive the placing frame 54 to rotate, thereby completing the projection of the basketball inside by the rotation of the placing frame 54.
