Description

Technical Field

[0001] The invention belongs to the technical field of sports equipment, in particular to a high-speed ball serving device. Background Art

[0002] The high-speed ball serving device is an important auxiliary tool in training. It can simulate different serving speeds and rotations to help players improve their reaction speed and hitting skills.

[0003] At present, in high-level table tennis competitions, high-speed topspin loops are the main form of confrontation, and the ball speed usually reaches more than 15m / s. For example, the highest ball speed in the competition reached 19.38m / s. However, existing table tennis serving machines are mainly powered by friction wheels, and they mainly serve at low and medium speeds. There is an upper limit to friction, making it difficult to achieve high-speed serving. The ball speed is generally less than 10

[0004] m / s, it is difficult to meet the training needs of high-level athletes. At the same time, when the friction wheel speed is too high, it is easy to damage the surface of the table tennis ball, affecting the performance and life of the ball. In addition, as the friction wheel wears more, it not only leads to the instability of the ball speed and rotation, but also the replacement of the friction wheel depends on professional technology, and it is difficult for ordinary consumers to complete the maintenance, which further increases the cost of use and the difficulty of maintenance. Another type of serving machine based on the impact principle (related patent technology) usually uses complex technologies such as bionic mechanical arms (patent number CN110772776A), visual recognition (patent number CN112297026A), and hydraulic presses (patent number CN111921180A) to simulate real hitting actions.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 15 As shown, the present invention provides a high-speed ball serving device, comprising a storage tank 1, a delivery pipe 2 is fixedly installed on one side of the storage tank 1, a delivery pipe 3 is rotatably connected to the top of the delivery pipe 2, and a spiral delivery component 4 is arranged inside the delivery pipe 2;

[0039] The beating assembly is arranged on one side of the outer surface of the conveying pipe 23, and the beating assembly includes a mounting plate 18, the mounting plate 18 is fixedly connected to one side of the outer surface of the conveying pipe 23, a driving device 19 is fixedly installed on one side of the mounting plate 18, a rotating arm 20 is fixedly installed on the output end of the driving device 19, a striking plate 21 is arranged on the top of the rotating arm 20, the rotating arm 20 and the striking plate 21 are hinged by an adjusting knob 22, and the striking plate 21 can rotate at the top of the rotating arm 20.

[0040] The operator pours the balls into the storage tank 1, and then drives the spiral conveying assembly 4 to convey the balls to the conveying pipe 23. When the balls are discharged from the conveying pipe 23, the driving device 19 can be driven to rotate the rotating arm 20, and the rotating arm 20 will drive the hitting plate 21 and the adjusting knob 22 to rotate, and then the rotating hitting plate 21 will contact the balls and hit the surface of the balls. Since the rotating arm 20 rotates at a fast speed, a high-speed serve is completed. In addition, the adjusting knob 22 can be rotated to drive the hitting plate 21 to rotate, and then the hitting angle of the hitting plate 21 can be adjusted to complete different types of serves.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes: a control mechanism, which is arranged inside the storage tank 1, the control mechanism includes a spring 5, the spring 5 is fixedly connected to the inside of the storage tank 1, and a sealing plate 6 is fixedly installed on the side of the spring 5 close to the conveying pipe 2. The number of the sealing plates 6 is two, and two connecting plates 7 are fixedly installed on one side of the two sealing plates 6, and a fixed plate 8 is fixedly installed on the opposite side of the two connecting plates 7. A motor 9 is fixedly installed on one side of the storage tank 1, and a cam 10 located on the opposite side of the two fixed plates 8 is fixedly installed on the output end of the motor 9.

[0042] The above scheme is adopted: the operator pours the ball into the interior of the storage tank 1, and then the ball flows into the interior of the conveying pipe 2. At this time, the motor 9 needs to be driven to rotate the cam 10. During the rotation of the cam 10, its two ends will contact the opposite side of the two fixed plates 8 and push the fixed plates 8 to move. The fixed plates 8 will drive the connecting plates 7 to move, and the connecting plates 7 will drive the blocking plates 6 to move. When the blocking plates 6 move, they will squeeze the spring 5. At this time, the ball will enter the interior of the conveying pipe 2. When the cam 10 rotates, the two ends of the cam 10 will move away from the surface of the fixed plates 8. At this time, the compressed spring 5 will push the blocking plates 6 to the conveying pipe 2. The surface of tube 2 moves, thereby blocking the conveying tube 2, so that the number of balls entering the interior of the conveying tube 2 can be controlled, and then the spiral conveying component 4 can be driven to drive the balls to pass through the conveying tube 2 and be discharged from the interior of the conveying tube 3, and then the slapping component can be driven to make it contact with the balls, thereby completing the serve, and finally the sealing plate 6 is moved back and forth by driving the motor 9, thereby controlling the number of balls entering the interior of the conveying tube 2, avoiding the balls entering the interior of the conveying tube 2 at one time and causing blockage, so that the device can serve the balls continuously and efficiently, without the need to frequently stop the machine to clean the blocked balls, thereby improving the overall serve efficiency.

[0043] like Figure 5 and Figure 6As shown, it also includes: an adjusting mechanism, which is arranged on the surface of the conveying pipe 2, the adjusting mechanism includes a protective shell 11, the protective shell 11 is fixedly connected to the surface of the conveying pipe 2, a gear ring 12 is fixedly installed on the bottom end of the surface of the conveying pipe 2, the interior of the protective shell 11 is rotatably connected to a rotating rod 13, a tooth plate 14 meshing with the gear ring 12 is arranged inside the protective shell 11, a motor 2 15 is fixedly installed on one side of the outer surface of the protective shell 11, the output end of the motor 2 15 extends to the interior of the protective shell 11, and a rotating disk 16 located inside the rotating rod 13 is fixedly installed, and a protrusion 17 located inside the rotating rod 13 is fixedly installed on one side of the tooth plate 14, and the protrusion 17 can slide inside the rotating rod 13.

[0044] The above scheme is adopted: through the design of the adjustment mechanism, when the slapping mechanism serves, the motor 2 15 can be driven to rotate the rotating disk 16, and the rotating disk 16 will slide inside the rotating rod 13, and then the rotating disk 16 will drive the rotating rod 13 to swing back and forth, and in the process of the rotating rod 13 swinging, the protrusion 17 will also slide inside the rotating rod 13, and then the swinging rotating rod 13 will drive the protrusion 17 and the tooth plate 14 to move back and forth, because the tooth plate 14 is engaged with the gear ring 12, and then the moving gear plate 14 will drive the gear ring 12 to rotate back and forth, and the gear ring 12 will drive the conveying tube 2 3 to rotate back and forth, through the rotation of the conveying tube 2 3, the slapping assembly can serve in different directions, and finally the conveying tube 2 3 can be rotated by driving the motor 2 15, so as to realize serving in different directions, which helps to improve the athlete's reaction speed, footwork movement ability and hitting accuracy, thereby comprehensively improving the technical level.

[0045] like Figure 1 and Figure 8 As shown, it also includes: a telescopic component, which is arranged on one side of the conveying pipe 23, the telescopic component includes a guide groove 24, the guide groove 24 is hinged to the conveying pipe 23 through an adjusting screw 36, the inside of the guide groove 24 is slidably connected with a telescopic groove 25, a rack 26 is fixedly installed inside one side of the telescopic groove 25, a driving device 27 is fixedly installed on one side of the guide groove 24, the output end of the driving device 27 extends to the inside of the guide groove 24, and a gear 28 meshing with the rack 26 is fixedly installed, a sensor 23 is fixedly installed on the side of the conveying pipe 23 close to the hitting plate 21, and synchronous door switches 35 are provided at both ends of the surface of the telescopic groove 25.

[0046] Through the design of the telescopic mechanism, when it is necessary to adjust the rolling distance of the ball, the device 27 can be driven to rotate the gear 28. Since the gear 28 is meshed with the rack 26, the gear 28 will drive the rack 26 and the telescopic slot 25 to move, and the telescopic slot 25 will move out of the guide slot 1 24, and then move it to the specified position. Then the ball inside the conveying pipe 23 will roll into the guide slot 1 24 and the telescopic slot 25, and contact with the synchronous door switch 35. Then, when the sensor 23 detects that the hitting plate 21 rotates to the bottom of the telescopic slot 25, the control system inside the device will drive the synchronous door switch 35 to move to both ends and cancel the obstruction to the ball. Then the ball will roll toward the surface of the hitting plate 21, and then the rotating hitting plate 21 will hit the ball, thereby reducing the phenomenon of empty shots, and the adjusting screw 36 can be rotated to rotate the guide slot 1 24 and the telescopic slot 25, so that the rolling angle of the ball is adapted to the angle of the hitting plate 21, so that the hitting plate 21 can send out different rotating balls.

[0047] like Figure 5 and Figure 6 As shown, a mounting block 29 is fixedly installed inside the protective shell 11, and a limiting block 30 is slidably connected inside the mounting block 29, and the top of the limiting block 30 is fixedly connected to the bottom end of the tooth plate 14, and two limiting rings 31 are fixedly installed on the surface of the conveying pipe 23, and the opposite sides of the two limiting rings 31 are in contact with the surface of the protective shell 11.

[0048] The above scheme is adopted: through the design of the mounting block 29 and the limit block 30, when the tooth plate 14 moves, the limit block 30 will be driven to slide inside the mounting block 29, and then the moving limit block 30 can limit the moving direction of the tooth plate 14, and the mounting block 29 can support the tooth plate 14. Through the design of the limit ring 31, when the conveying pipe 23 rotates, the two limit rings 31 will rotate accordingly. Since the opposite sides of the limit ring 31 are in contact with the surface of the protective shell 11, the conveying pipe 23 can be limited when rotating.

[0049] like Figure 2 and Figure 3 As shown, a fixed groove 32 is opened inside one side of the storage slot 1, and a limiting block 33 is slidably connected inside the fixed groove 32. There are four limiting blocks 33, and each two limiting blocks 33 form a group, and the opposite sides of the two limiting blocks 33 are in contact with the two ends of the connecting plate 7. A guide plate 34 is fixedly installed inside the storage slot 1, and the top of the guide plate 34 is designed to be arc-shaped.

[0050] The above scheme is adopted: through the design of the fixed groove 32 and the limit block 33, when the connecting plate 7 moves, the limit block 33 will be driven to slide inside the fixed groove 32. Since the surface of the limit block 33 is in contact with the inner wall of the fixed groove 32, the connecting plate 7 can be limited when the limit block 33 rotates. Through the design of the guide plate 34, when the ball is poured into the storage groove 1, the ball will fall on the top of the guide plate 34. Since the top of the guide plate 34 is designed to be arc-shaped, it is convenient for the guide plate 34 to guide the ball into the interior of the conveying pipe 2.

[0051] like Figure 4 and Figure 6 As shown, a circular groove is provided at the top of the protective shell 11, and the size of the circular groove is larger than the conveying pipe 2 3. There are four springs 5, and each spring 5 is a group of two, and they are all located on the opposite side of the two blocking plates 6.

[0052] The above scheme is adopted: through the design of the protective shell 11, since a circular groove is opened at the top of the protective shell 11 and the size is larger than the conveying tube 2 3, the protective shell 11 will not interfere with the rotation of the conveying tube 2 3, and through the design of the spring 5, since the springs 5 ​​are grouped in pairs, when the cam 10 is away from the fixed plate 8, the two compressed springs 5 ​​will simultaneously push the blocking plate 6 to reset, thereby improving the stability of the movement of the blocking plate 6.

[0053] like Fig.11 As shown, the serving method is to add spin to the loop ball, and hit the ball in the upper middle position with force; Fig.12 As shown, the serving method is a backspin ball, with the force applied diagonally downward to hit the lower middle part of the ball; Fig.13 As shown in the figure, the serving method is to not spin the ball, but to exert force forward and hit the middle and lower part of the ball; Fig.14 As shown, the serving method is to bounce the ball, exert force diagonally downward, and hit the upper middle part of the ball; Fig.15 As shown, the serving method is a forward loop ball, with force forward, hitting the ball in the middle and upper position, such as Figure 11-Figure 15 The direction of the arrow in the middle is the direction of force.

[0054] The working principle and use process of the present invention:

[0055] First, the operator can pour the balls into the storage tank 1, and then drive the motor 9 to rotate the cam 10, which will push the fixed plate 8, the connecting plate 7 and the blocking plate 6 to move toward both ends, and the spring 5 will be compressed, and then the ball will enter the inside of the conveying tube 2. During the rotation of the cam 10, it will move away from the surface of the fixed plate 8, and then the compressed spring 5 will push the blocking plate 6 to block the conveying tube 2, thereby controlling the number of balls entering the conveying tube 2. Then, the spiral conveying assembly 4 can be driven, and then the ball will roll from the inside of the conveying tube 2 3 into the inside of the guide groove 24 and the telescopic groove 25, and will contact the synchronous door switch 35. When the sensor 23 detects that the hitting plate 21 rotates to the bottom of the telescopic groove 25, the control system will drive the synchronous door switch 35 to move toward both ends to cancel the blockage of the ball, and then the hitting plate 21 will hit the fallen ball, thereby completing the serve.

[0056] During the serving process, the motor 2 15 can be driven to rotate the rotating disk 16, and the rotating disk 16 will drive the rotating rod 13 to swing back and forth. At this time, during the swinging of the rotating rod 13, the protrusion 17 will also slide inside the rotating rod 13, and then the rotating rod 13 will drive the protrusion 17 and the tooth plate 14 to move back and forth, the tooth plate 14 will drive the gear ring 12 to rotate back and forth, and the gear ring 12 will drive the conveying tube 2 3 to rotate back and forth. Through the rotation of the conveying tube 2 3, it can simulate serves at different angles and positions in the game, increase the diversity and practicality of training, and finally complete the operation process.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
