Abstract
Description
Technical Field
[0001] This invention belongs to the field of ball launching machine technology, specifically relating to a ball launcher. Background Technology
[0002] A ball-serving machine is a training aid for ball sports. Currently, ball-serving machines use two main methods: top-down and bottom-up. In the bottom-up method, the ball enters the machine and is then pushed outwards by a squeezing and friction mechanism. However, this squeezing and friction method easily causes severe wear or damage to the ball's surface during transport. Over time, this can lead to air leakage, causing the ball to become stuck inside the machine and resulting in malfunction. Summary of the Invention

[0012] A lever rotation shaft is fixedly connected to the lever follower shaft, and a lever arm is provided at the end of the lever rotation shaft away from the lever follower shaft;
[0013] The first guide plate is provided with a first guide ramp and a second guide ramp, and the second guide plate is provided with a third guide ramp and a fourth guide ramp.
[0014] Two lever guides are provided on one end of the lever rotation shaft near the lever follower shaft. The lever guides are respectively engaged with the first guide ramp, the second guide ramp, the third guide ramp, and the fourth guide ramp.
[0015] Furthermore, an active area is provided on the side of the first guide plate at the end connected to the follower shaft of the lever, and the first guide ramp and the second guide ramp are respectively provided at both ends of the active area.

[0018] Furthermore, a connecting rod is provided on the rotating shaft of the lever, and the lever guide is disposed on the connecting rod.
[0019] Furthermore, the lever guide is a spherical structure.
[0020] Furthermore, the drive assembly includes a drive member and a fixed base, the drive member is disposed on the fixed base, and the drive end of the drive member passes through the fixed base and is connected to the follower shaft of the lever;
[0021] A follower shaft rotation sensor trigger rod is provided on one side of the lever follower shaft;
[0022] The fixed base is provided with a sensor fixing plate and a follower shaft rotation limit sensor, and the follower shaft rotation sensor trigger rod cooperates with the follower shaft rotation limit sensor.
[0023] Furthermore, the driving component is a motor.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. This ball-serving machine replaces the existing ball-feeding machine's roller friction method with a ball-feeding method by installing a ball-pushing device inside the frame. When the ball enters the ball-serving machine, after the detection element detects the ball at the detection point, the ball-pushing device pushes the ball located on the guide to the guide's outlet end, causing the corresponding roller ball-feeding device to launch the ball. The entire ball-pushing process does not cause wear on the ball surface, thus improving the ball's service life and preventing the ball-serving machine from malfunctioning.
[0026] 2. The ball-pulling device includes a drive assembly and a ball-pulling assembly. The ball-pulling assembly is installed on the drive end of the drive assembly. The drive assembly drives the ball-pulling assembly to perform the plucking operation, which can improve the reliability of the ball-pulling to a certain extent and ensure that the ball can be output smoothly.
[0027] 3. The lever rotation shaft is installed between the first guide plate and the second guide plate. The limiting effect of the first and second guide plates ensures that the lever rotation shaft remains centered on the ball during the paddle motion, allowing for smooth movement. Secondly, installing a lever arm on the lever rotation shaft indirectly increases the contact area between the lever rotation shaft and the ball's surface, ensuring the paddle force is fully applied to the ball's surface. Finally, to ensure the lever rotation shaft smoothly resets after the ball is moved, preventing jamming due to the lever arm, first and second guide ramps are provided on the first guide plate, and third and fourth guide ramps are provided on the second guide plate. Two lever guide components are installed on the lever rotation shaft. During the reset process, the two lever guide components cooperate with the first, second, third, and fourth guide ramps, allowing the lever arm to adjust its angle as it rotates with the lever rotation shaft, facilitating smooth passage.
[0028] 4. The active area opened on the first guide plate can provide a path track for one of the lever guides, so that it can contact the first guide ramp and the second guide ramp.
[0029] 5. The active area adopts a hollow structure with an arc-shaped cross-section, which allows one of the lever guides to move within the active area while rotating around the first guide plate along with the lever's rotation axis.
[0030] 6. The third and fourth guide ramps are located at the top and bottom of the second guide plate. During the reset process of the lever rotation shaft, another lever guide component cooperates with the third and fourth guide ramps to smoothly adjust the working angle of the lever rotation shaft and lever arm.
[0031] 7. The lever guide is mounted on the lever rotation shaft via a connecting rod, which improves the stability of the installation.
[0032] 8. The lever guide adopts a spherical structure, which can avoid jamming during the process of cooperating with the first, second, third and fourth guide ramps.
[0033] 9. The installation of the follow-up shaft rotation limit sensor enables more accurate resetting of the lever rotation shaft.
[0034] 10. The ball-pulling device is made entirely of metal, thus avoiding any impact on the environment. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0062] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0063] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0064] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0065] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0066] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0067] To address the problem of wear and tear on the ball surface caused by the use of rollers for ball delivery in existing ball-launching machines, which affects the ball's lifespan, this invention provides a ball launcher that can be widely used in training for ball sports such as basketball, football, and volleyball. This embodiment uses basketball as an example for illustration.
[0068] like Figure 1 As shown, this embodiment of the invention provides a ball launcher, which includes: a frame 301, a guide 302 and a side rail 303 provided within the frame 301, the guide 302 being located below the side rail 303 to ensure that the ball 401 remains within the path planned by the side rail 303 during rolling; wherein one end of the guide 302 is an inlet end and the other end is an outlet end, the inlet end being used to roll the ball 401 into the frame 301, and the outlet end being used to output the ball 401 outward to the trainee; a detection point 501 is provided in the middle of the guide 302, from... Figure 1As can be seen, after the ball 401 enters the frame 301 through the guide 302, it will roll along the path planned by the inlet end of the guide 302 and the side guardrail 303 to the detection point 501. The roller ball launching device 201 is installed on the frame 301 and is located above the guide 302, corresponding to the outlet end of the guide 302, so that the ball 401 can be sent outward by the roller ball launching device 201. The ball-pushing device 101 installed on the frame 301 is located on one side of the roller ball launching device 201. The ball-pushing device 101 is used to push the ball 401 located at the detection point 501 to the outlet end of the guide 302. In order for the ball-pushing device 101 to start the operation accurately, such as Figure 23 and Figure 24 As shown, a detection element is provided on the ball-feeding device 101. The detection end of the detection element faces the detection point 501. The ball-feeding device 101 can be activated by detecting changes in the distance between the detection element and the detection point 501, or by detecting whether there is an obstacle between the detection element and the detection point 501. When the detection element activates the ball-feeding device 101 by detecting changes in distance, the detection element can preferably be an ultrasonic ranging sensor. When the detection element activates the ball-feeding device 101 by detecting whether there is an obstacle, the detection element can preferably be one of an ultrasonic sensor, an infrared sensor, or a vision sensor. It should be noted that the above sensors can all be purchased commercially, and this embodiment does not involve secondary modifications to the sensors. Finally, in order to realize the automated operation of the transmitter, a controller is also installed on the frame 301. This controller can also be purchased commercially. The controller is electrically connected to the ball-feeding device 101, the roller ball-feeding device 201, and the detection element.
[0069] refer to Figures 10 to 14 In this embodiment, the guide member 302 includes guide rods and guide wheels. Two guide rods are provided, and the guide wheels are located on opposite sides of the two guide rods. After the ball 401 rolls to the detection point 501 via the guide wheels, the detection member sends the detection signal to the controller. The controller then controls the ball-feeding device 101 and the roller ball-launching device 201 to start operation based on the received signal, thus moving the ball 401. During the movement, the ball 401 rolls along the direction of the exit end of the guide member 302. Figure 11 As shown, when the ball-feeding device 101 moves the ball 401 to the outlet end of the guide 302, one end of the ball 401 contacts the roller ball-launching device 201, while the other end of the ball 401 continues to move under the pushing force of the ball-feeding device 101. After the ball 401 is launched by the rotating roller ball-launching device 201, as... Figure 12 , Figure 13 and Figure 14 As shown, the ball-pulling device 101 is reset.
[0070] In this embodiment, the ball-feeding device 101 includes a driving assembly and a ball-feeding assembly. One end of the ball-feeding assembly is mounted on the driving end of the driving assembly, and the other end is fixedly connected to the frame 301. The detection element is disposed on the driving assembly. Specifically, as shown... Figure 2 and Figure 3 As shown, the ball-handling assembly includes a first guide plate 1031 and a second guide plate 1033. Both the first guide plate 1031 and the second guide plate 1033 have circular holes, while the outer side of the lever follower shaft 1011 has two opposing mounting holes. Figure 4 As shown, a plane bearing 1012 is first installed at the end of the lever rotation shaft 1010, and then passes through two opposite mounting holes on the outside of the lever follower shaft 1011. A plane bearing 1012 and a fixing nut 1013 are sequentially installed on the outside of the lever rotation shaft 1010, and then fixed with a lever fixing screw 1017. After fixing, the follower shaft fixing plate 1014 is welded to one side of the follower shaft D-type fixing plate 1015, and the follower shaft rotation sensor trigger rod 1016 is welded to the other side of the follower shaft D-type fixing plate 1015. The end of the follower shaft 1011 passes through the follower shaft fixing plate 1014 and connects to one side of the follower shaft D-type fixing plate 1015. Figure 4 The outer side of the sensor trigger rod 1016, which is away from the fixed follower shaft D-shaped fixing plate 1015, protrudes outward.
[0071] like Figures 3-5 As shown, a follower shaft bearing limiting piece 1035 is installed on the circular hole on the opposite side of the first guide plate 1031 and the second guide plate 1033. Then, a follower shaft rotating bearing 1036 is installed in the circular hole opened in the first guide plate 1031 and the second guide plate 1033, and is limited by the follower shaft bearing limiting piece 1035. One of the follower shaft rotating bearings 1036 is equipped with a follower shaft retaining ring 1037. Finally, a first guide plate fixing seat 1032 is installed on the end of the first guide plate 1031, and a second guide plate fixing seat 1034 is installed on the end of the second guide plate 1033. The first guide plate 1031 and the second guide plate 1033 are fixed on the frame 301 by the first guide plate fixing seat 1032 and the second guide plate fixing seat 1034. At this time, the follower shaft 1011 of the lever is rotatably connected between the first guide plate 1031 and the second guide plate 1033.
[0072] like Figure 6As shown, the drive assembly includes a drive component 1021 and a fixed base. The fixed base includes a drive component fixed base A1024 and a drive component fixed base B1025. One end of the drive component fixed base B1025 is connected to the first guide plate 1031, and the other end of the drive component fixed base B1025 is connected to the drive component fixed base A1024. The drive component 1021 is disposed on the drive component fixed base A1024, and the drive end of the drive component 1021 passes through the drive component fixed base A1024 and is connected to the lever follower shaft 1011. A sensor fixing piece 1022 and a follower shaft rotation limit sensor 1023 are also provided on the drive component fixed base A1024. The follower shaft rotation sensor trigger rod 1016 cooperates with the follower shaft rotation limit sensor 1023.
[0073] The end of the follower shaft 1011 passes through the follower shaft fixing plate 1014 and is connected to one side of the follower shaft D-shaped fixing plate 1015. The drive end of the drive assembly passes through the follower shaft rotation sensor trigger rod 1016 and is connected to the other side of the follower shaft D-shaped fixing plate 1015. During the process of the drive assembly driving the follower shaft D-shaped fixing plate 1015 to rotate, the follower shaft 1011, the follower shaft fixing plate 1014 and the follower shaft rotation sensor trigger rod 1016 are rotated in sequence.
[0074] In this embodiment, the driving component 1021 is preferably a motor. During the rotation of the lever follower shaft 1011, the driving component 1021 drives the lever rotation shaft 1010 to rotate, thereby realizing the lever rotation shaft 1010's turning operation. During the rotation of the lever rotation shaft 1010, the follower shaft rotation sensor trigger rod 1016 also rotates. After the ball 401 is launched, during the reset process of the lever rotation shaft 1010 through the driving component 1021, the follower shaft rotation sensor trigger rod 1016 contacts the follower shaft rotation limit sensor 1023, the driving component 1021 stops driving, and the lever follower shaft 1011 is reset, without affecting the subsequent turning operation of the ball 401.
[0075] like Figures 5-6 As shown, to ensure the reliability of the actuation operation, a lever arm 10110 is provided at the end of the lever rotation shaft 1010 away from the lever follower shaft 1011. The lever arm 10110 is a rod-shaped structure and is symmetrically arranged. The arrangement of the lever arm 10110 can indirectly increase the contact area between the lever rotation shaft 1010 and the surface of the ball 401, so that the actuation force is fully applied to the surface of the ball 401; secondly, as Figure 9As shown, a lever limiting platform 10111 and two lever guide members 1018 are provided on one end of the lever rotation shaft 1010 near the lever follower shaft 1011. The two lever guide members 1018 are spaced apart, and the lever guide members 1018 are preferably spherical. The two lever guide members 1018 are connected to the lever rotation shaft 1010 through connecting rods 1019, and the two connecting rods 1019 are axially perpendicular to each other. The two lever guide members 1018 are located above the lever limiting platform 10111. Finally, as Figure 7 and Figure 8 As shown, the side of the first guide plate 1031 connected to the lever follower shaft 1011 has an active area. The first guide ramp 10311 and the second guide ramp 10312 are respectively set at both ends of the active area. The active area has a hollow structure and an arc-shaped cross-section, which can provide a path track for one of the lever guide members 1018. While it contacts the first guide ramp 10311 and the second guide ramp 10312, it can also make one of the lever guide members 1018 rotate around the first guide plate 1031 along with the lever rotation shaft 1010. The second guide plate 1033 is provided with the third guide ramp 10331 and the fourth guide ramp 10332, which have the same structure. After the drive member 1021 drives the lever rotation shaft 1010 to rotate and move the ball 401, during the rotation and reset process of the lever rotation shaft 1010, the lever guide member 1018 makes contact with the first guide ramp 10311, the second guide ramp 10312, the third guide ramp 10331 and the fourth guide ramp 10332 respectively, so that the angle of the lever rotation shaft 1010 can be adjusted, and the lever arm 10110 is prevented from getting stuck between the first guide plate 1031 and the second guide plate 1033.
[0076] In the specific operation process, such as Figures 15-20 As shown, during the rotation and reset process of the lever rotation shaft 1010, one lever guide 1018 is located within the active area, and the other lever guide 1018 contacts the third guide ramp 10331, thereby causing the lever arm 10110 to rotate on the lever follower shaft 1011. The lever arm 10110 can then smoothly pass through the area between the first guide plate 1031 and the second guide plate 1033. Figure 21 As shown, after the lever arm 10110 passes through the area between the first guide plate 1031 and the second guide plate 1033, as... Figure 22 As shown, one of the lever guides 1018 contacts the second guide ramp 10312, and the other lever guide 1018 contacts the fourth guide ramp 10332, ultimately adjusting the direction of the lever arm 10110.
[0077] like Figure 1As shown, in this embodiment, the roller ball-serving device 201 includes rollers and servo motors. The rollers are symmetrically arranged, and a servo motor is installed on each of the two rollers.
[0078] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
