[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] The following describes a six-wheel tennis ball launcher 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, the six-wheel tennis ball launcher 100 according to an embodiment of the present invention includes a vehicle body 1, a transport component 2 and a launch component 3.

[0029] The vehicle body 1 has a temporary storage compartment 11, which is used to store tennis balls. Figure 4 As shown, a temporary storage bin 11 is provided on the upper end surface of the vehicle body 1, and the temporary storage bin 11 is used to store tennis balls to meet the needs of long-term training or competition.

[0030] The transport assembly 2 is disposed on the vehicle body 1 and one end of the transport assembly 2 is connected to the temporary storage bin 11, so that the tennis balls in the temporary storage bin 11 are transported by the transport assembly 2. Figure 1-Figure 4As shown, the transport component 2 is arranged on the vehicle body 1, and the inlet of the transport component 2 is connected with the outlet of the temporary storage bin 11, and a smooth tennis ball transmission channel is formed in the transport component 2, so that the tennis balls in the temporary storage bin 11 can be transported to the next link in an orderly and stable manner through the transport component 2, thereby improving the continuity and efficiency of tennis ball launching and reducing the labor intensity of operators.

[0031] The launching assembly 3 includes a launching tube 31, a first launching member 32 and a second launching member 33. The launching tube 31 is arranged on the transport assembly 2 and communicates with the transport assembly 2 so that the tennis ball in the transport assembly 2 is transported to the launching tube 31. The launching tube 31 is arranged relative to the vehicle body 1 in the width direction of the vehicle body 1 (such as Figure 2 The launch tube 31 is rotatable (in the front and rear directions shown in the figure) to adjust the launch angle of the launch tube 31. The first launch member 32 and the second launch member 33 are both arranged on the launch tube 31 and at least part of the first launch member 32 and the second launch member 33 are located in the launch tube 31. The first launch member 32 is used to position the tennis ball. The second launch member 33 is located on the side of the first launch member 32 away from the transport assembly 2. The second launch member 33 is used to accelerate the tennis ball. Specifically, as shown in FIG. Figure 1 , Figure 6 and Figure 7 As shown, the launch tube 31 is arranged on the right side of the transport component 2 and is connected to the transport component 2, ensuring that the tennis ball can smoothly enter the launch tube 31 from the transport component 2. The launch tube 31 can be rotated along the front and rear directions on the transport component 2, and the launch angle of the launch tube 31 can be adjusted according to actual needs. In addition, the first launch member 32 and the second launch member 33 are both arranged on the launch tube 31, and at least part of the first launch member 32 and the second launch member 33 pass through the launch tube 31 and are located in the launch tube 31. The function of the first launch member 32 is to position the tennis ball. After the tennis ball is transported into the launch tube 31, the first launch member 32 can ensure that the tennis ball is in the correct launching position. If the position of the tennis ball is inaccurate, the subsequent acceleration and launching will be affected, which will cause the launching direction to deviate or the launching force to be insufficient. Therefore, the accuracy and stability of the tennis ball launching are improved through the precise positioning of the first launch member 32. The second launching element 33 is used to accelerate the tennis ball and is located at the right end of the first launching element 32. When the tennis ball is accurately positioned and launched by the first launching element 32, the second launching element 33 drives the tennis ball to accelerate so that the tennis ball gains a sufficient speed to be successfully launched. Thus, the coordinated work of the first launching element 32 and the second launching element 33 ensures that the tennis ball can be accurately and efficiently launched, thereby improving the accuracy and stability of the tennis ball launching and enhancing the continuity and efficiency of the tennis ball launcher.

[0032] The six-wheel tennis ball launcher 100 of the embodiment of the present invention is provided with a vehicle body 1, a transport component 2 and a launch component 3. The vehicle body 1 drives the transport component 2 and the launch component 3 to move on the playing field, so that the transport component 2 and the launch component 3 are transported to a preset position. The tennis ball is transported by the transport component 2, thereby ensuring the smoothness of the launch of the six-wheel tennis ball launcher 100. The tennis ball is pre-positioned by the first launch component 32 of the launch component 3 to ensure that the tennis ball is in the correct launch position, thereby reducing the ballistic deviation and improving the hit rate of the six-wheel tennis ball launcher 100. The tennis ball is accelerated by the second launch component 3 to ensure the launch speed of the tennis ball and improve the launch efficiency of the six-wheel tennis ball launcher 100.

[0033] In some embodiments, the first launching member 32 includes a first driving wheel 321, a second driving wheel 322 and a third driving wheel, which are arranged on the launching tube 31 at equal intervals along the circumference of the launching tube 31 and are all rotatable relative to the launching tube 31, and the first driving wheel 321, the second driving wheel 322 and the third driving wheel define a positioning cavity so that the tennis ball is located in the positioning cavity to position the tennis ball. Specifically, as Figure 1 , Figure 6 and Figure 7 As shown, the first drive wheel 321, the second drive wheel 322 and the third drive wheel are all arranged on the launch tube 31, and the first drive wheel 321, the second drive wheel 322 and the third drive wheel are arranged at equal intervals along the circumference of the launch tube 31, thereby ensuring the balanced force between the first drive wheel 321, the second drive wheel 322 and the third drive wheel, and ensuring that the tennis ball can be supported stably in all directions in the positioning cavity. The first drive wheel 321, the second drive wheel 322 and the third drive wheel are driven by built-in motors respectively, so that the first drive wheel 321, the second drive wheel 322 and the third drive wheel can adjust the speed and steering as needed to adapt to the requirements of different launch angles and strengths. When the tennis ball is transported to the launch tube 31 through the transport assembly 2, the tennis ball will be uniformly squeezed and supported by the first drive wheel 321, the second drive wheel 322 and the third drive wheel, so that it is accurately positioned in the positioning cavity, thereby not only improving the accuracy of the launch, but also effectively preventing the tennis ball from shaking and deflecting during the launch process.

[0034] In addition, compared with two driving wheels, the three driving wheels, namely the first driving wheel 321, the second driving wheel 322 and the third driving wheel, can not only more effectively prevent the tennis ball from shaking in the positioning cavity, but also the tennis ball needs to remain stationary or slightly move before launching so that the second launching member 33 can accurately accelerate it. Secondly, the three driving wheels are arranged at equal intervals along the circumference of the launch tube 31, which can ensure that the tennis ball is subjected to uniform squeezing force and supporting force in the positioning cavity. The balanced force state helps to maintain the stable posture of the tennis ball and prevent it from shifting or tilting before launching. Finally, the specifications of the tennis ball (such as diameter, weight, etc.) may vary depending on the brand, model or competition requirements. The design of the three driving wheels can accommodate tennis balls of different specifications, ensuring that they can all be stably supported and positioned in the positioning cavity. This improves the versatility and compatibility of the transmitter.

[0035] In some embodiments, the second launching member 33 includes a fourth driving wheel 331, a fifth driving wheel 332, and a sixth driving wheel, which are arranged on the launching tube 31 at equal intervals along the circumference of the launching tube 31 and are all rotatable relative to the launching tube 31, and the fourth driving wheel 331, the fifth driving wheel 332, and the sixth driving wheel define an acceleration cavity, so that when the tennis ball passes through the acceleration cavity, the fourth driving wheel 331, the fifth driving wheel 332, and the sixth driving wheel accelerate the tennis ball. Specifically, as Figure 1 , Figure 6 and Figure 7As shown, the fourth driving wheel 331, the fifth driving wheel 332 and the sixth driving wheel are all arranged on the launching tube 31, and the fourth driving wheel 331, the fifth driving wheel 332 and the sixth driving wheel are arranged at equal intervals along the circumference of the launching tube 31 to ensure that the tennis ball can be subjected to uniform and effective driving force during the launching process. The fourth driving wheel 331, the fifth driving wheel 332 and the sixth driving wheel are driven by built-in motors respectively, so that the fourth driving wheel 331, the fifth driving wheel 332 and the sixth driving wheel can adjust the speed and direction as needed, and the fourth driving wheel 331, the fifth driving wheel 332 and the sixth driving wheel can be adjusted according to different launching requirements. For example, the launch angle and strength can be adjusted by changing the rotation speed and direction of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel, so as to meet different competition or training requirements and adapt to different launch angles and strength requirements. The fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel form an acceleration cavity in arrangement. The acceleration cavity can maximize the launch speed and accuracy of the tennis ball. When the tennis ball is sent into the acceleration cavity, it will be simultaneously driven by the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel. Through the synergistic effect of the driving force, the tennis ball is accelerated so that it can obtain sufficient kinetic energy in a short time, so that it can be launched at a high speed and in a stable state, thereby improving the launch efficiency of the tennis ball.

[0036] In addition, under the premise of ensuring acceleration efficiency and stability, the design of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel also takes cost-effectiveness into consideration. Too many drive wheels will increase manufacturing and maintenance costs, and two drive wheels may not meet the requirements of acceleration efficiency and stability, and cannot provide sufficient support and guidance for the tennis ball, causing the tennis ball to shake or deviate during acceleration. Therefore, the setting of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel, while ensuring the processing and manufacturing costs of the six-wheel tennis ball launcher 100, also meets the performance requirements of the tennis ball launcher.

[0037] In some embodiments, the angular velocities of the first drive wheel 321, the second drive wheel 322 and the third drive wheel are equal, the angular velocities of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel are equal, and the ratio of the angular velocity of the first drive wheel 321 to the angular velocity of the fourth drive wheel 331 is 1:2. Specifically, the diameters and angular velocities of the first drive wheel 321, the second drive wheel 322 and the third drive wheel are equal, so that the first drive wheel 321, the second drive wheel 322 and the third drive wheel provide uniform squeezing and supporting forces to the tennis ball, which helps prevent the tennis ball from shaking or deflecting in the positioning cavity, ensuring that the tennis ball is in a stable state before launching, and the uniform force distribution can also reduce the wear between the drive wheel and the tennis ball, and extend the service life of the device. In other words, when the angular velocities of the first drive wheel 321, the second drive wheel 322 and the third drive wheel are inconsistent, the tennis ball will be subjected to uneven squeezing forces in the positioning cavity, thereby accelerating the wear of the first drive wheel 321, the second drive wheel 322, the third drive wheel and the tennis ball. In addition, the first driving wheel 321, the second driving wheel 322 and the third driving wheel with equal angular velocities can ensure that when launching a tennis ball, the force state of the tennis ball is consistent each time it is launched, thereby improving the consistency of the launch. If the angular velocities of the first driving wheel 321, the second driving wheel 322 and the third driving wheel are inconsistent, the launch speed and angle of the tennis ball will deviate from the predetermined value, affecting the accuracy of the launch.

[0038] The angular velocity and radius of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel are all equal, so that the driving force applied to the tennis ball by the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel will be more uniform, which helps to ensure that the tennis ball is subjected to a stable acceleration during the acceleration process, thereby achieving a stable and controllable launch speed. In addition, the uniform angular velocity distribution can improve the efficiency of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel in converting mechanical energy into kinetic energy of the tennis ball. When the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel rotate at the same angular velocity, the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel can more efficiently transmit power to the tennis ball, so that the tennis ball reaches the required launch speed in a shorter time. Secondly, the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel with equal angular velocities can reduce unnecessary energy consumption. If the angular velocities of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel are inconsistent, additional energy is required to overcome the uneven driving force, which will increase the energy consumption of the device and reduce its efficiency. Finally, if the angular velocities of the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel are inconsistent, the tennis ball may be subjected to uneven driving force during acceleration, resulting in deviation or deviation from the predetermined launch trajectory.

[0039] The first drive wheel 321, the second drive wheel 322, and the third drive wheel are responsible for sending the tennis ball into the initial stage of the launch path, while the fourth drive wheel 331, the fifth drive wheel 332 and the sixth drive wheel are responsible for providing additional acceleration when the tennis ball is about to leave the transmitter. According to the inventor's experiments, if the angular velocity ratio of the first drive wheel 321 to the angular velocity of the fourth drive wheel 331 is set too small, the rotation speed of the first drive wheel 321 in the initial stage will be relatively high, causing the tennis ball to obtain too fast a speed in the initial stage, which may cause the tennis ball to lose control on the launch path and may even cause the launch to fail. Compared with the initial stage, the rotation speed of the drive wheels in the acceleration stage will also increase, but it may not provide enough speed increment to meet the acceleration requirements of the tennis ball, which may cause the speed of the tennis ball to be insufficient when leaving the transmitter and fail to reach the predetermined launch speed and trajectory. If the angular velocity ratio of the first driving wheel 321 to the angular velocity of the fourth driving wheel 331 is set too large, the driving wheel speed in the initial stage will be relatively low, resulting in the tennis ball obtaining too slow a speed in the initial stage, which may require more energy and time for the tennis ball to reach the predetermined speed in the subsequent acceleration stage, thereby affecting the launch efficiency, and the fourth driving wheel 331 in the acceleration stage may over-accelerate the tennis ball, resulting in the tennis ball leaving the transmitter at too fast or unstable speed, increasing the uncertainty of the tennis ball during flight and reducing the accuracy of the launch. In summary: by setting the angular velocity ratio of 1:2, it is possible to ensure that the tennis ball obtains an appropriate speed increment when passing through these two stages, thereby achieving the predetermined launch speed and trajectory.

[0040] In some embodiments, the six-wheel tennis ball launcher 100 further includes a dial 4, which is disposed in the temporary storage bin 11 and is rotatable relative to the temporary storage bin 11 in the vertical direction. The outer circumference of the dial 4 and the inner circumference of the temporary storage bin 11 are arranged at intervals along the inner and outer directions. The dial 4 is provided with a plurality of through holes 41 penetrating the dial 4 in the vertical direction. The plurality of through holes 41 are arranged at intervals along the circumference of the dial 4. Tennis balls can be arranged in the through holes 41, so that the dial 4 can rotate the tennis balls to move the tennis balls into the transport assembly 2. Specifically, as Figure 4 As shown, the dial 4 is a horizontal disk and is arranged in the temporary storage bin 11. The dial 4 is driven by a motor to make the dial 4 rotate in the temporary storage bin 11. The outer peripheral surface of the dial 4 is provided with a plurality of through holes 41 that penetrate the dial 4 in the up and down directions. The plurality of through holes 41 are arranged at equal intervals along the circumference of the dial 4. Each through hole 41 can accommodate a tennis ball. When the dial 4 rotates, the dial 4 drives the tennis ball to rotate in the temporary storage bin 11. The inlet of the transport component 2 is arranged below the temporary storage bin 11 and is arranged opposite to the dial 4 in the up and down directions, so that the tennis ball can smoothly flow into the transport component 2 through the dial 4.

[0041] In some embodiments, the six-wheel tennis ball launcher 100 further includes a mounting frame 5, which is disposed on the vehicle body 1 and is rotatable relative to the vehicle body 1 in an up-and-down direction, a launching assembly 3 is disposed on the mounting frame 5 and is rotatable relative to the mounting frame 5 in a width direction of the vehicle body 1, and a transport assembly 2 includes a first transport tube 21 and a second transport tube 22, the first transport tube 21 is disposed on the vehicle body 1 and one end of the first transport tube 21 is connected to the temporary storage bin 11, and the other end of the first transport tube 21 is connected to one end of the second transport tube 22, and the second transport tube 22 is disposed on the mounting frame 5 and is connected to the launching assembly 3. Specifically, as Figure 1 and Figure 2 As shown, the mounting frame 5 is arranged on the vehicle body 1 and can rotate on the vehicle body 1 in the up and down directions, the launching assembly 3 is arranged on the mounting frame 5 and can rotate on the mounting frame 5 in the front and back directions, so that the launching angle of the launching assembly 3 is adjusted by the mounting frame 5 to meet the serving requirements in different scenarios, a part of the first transport tube 21 is located below the temporary storage bin 11 and the first transport tube 21 is connected to the temporary storage bin 11, so that another part in the temporary storage bin 11 extends in the up and down directions and is connected to the second transport tube 22, the second transport tube 22 is arranged on the mounting frame 5 and is connected to the launching assembly 3, thereby, the tennis ball is transported to the launching assembly 3 through the first transport tube 21 and the second transport tube 22.

[0042] It is worth mentioning that the rotation of the mounting frame 5 can be driven by a motor, and a threaded rod 8 can be provided on the left side of the launching component 3. The upper end of the threaded rod 8 is connected to the launching component 3, and the lower end of the threaded rod 8 is connected to the mounting frame 5 through a nut. Therefore, by rotating the nut, the threaded rod 8 moves in the up and down directions, thereby driving the launching component 3 to rotate around the front and back directions.

[0043] In some embodiments, the transport assembly 2 further includes a plurality of first rotating rollers 23, which are sequentially arranged on the first transport tube 21 along the extension direction of the first transport tube 21, and / or a plurality of second rotating rollers, which are sequentially arranged on the second transport tube 22 along the extension direction of the second transport tube 22. Thus, the first rotating rollers 23 are rotatably mounted on the first transport tube 21, and the second rotating rollers are rotatably arranged on the second transport tube 22, and the transport efficiency of the transport assembly 2 is improved by the first rotating rollers 23 and the second rotating rollers, and the entire transport process is made more stable and reliable.

[0044] In some embodiments, the second transport tube 22 is located on one side of the mounting frame 5, and the axis of the upper end of the second transport tube 22 coincides with the rotation axis of the launch tube 31. Figure 2 and Figure 6As shown, the second transport tube 22 is arranged on the front side of the mounting frame 5 and is substantially C-shaped. The lower end of the second transport tube 22 is connected to the first transport tube 21, and the upper end of the second transport tube 22 is connected to the launching tube 31. The extension direction of the upper end of the second transport tube 22 coincides with the rotation axis of the launching tube 31. Therefore, when the second transport tube 22 rotates in the front-to-back direction, it can be ensured that the second transport tube 22 is always connected to the launching tube 31, thereby ensuring the continuity and stability of the tennis ball during the transmission process.

[0045] In some embodiments, the six-wheel tennis ball launcher 100 further includes a pushing assembly (not shown in the figure), which is disposed in the launch tube 31 and is movable relative to the launch tube 31 along the axis of the launch tube 31, so that the pushing assembly pushes the tennis ball to the first launch member 32. Specifically, the pushing assembly is a push rod, a part of which is disposed in the launch tube 31 and is movable in the launch tube 31 along the left and right directions. When the tennis ball moves in the transport assembly 2, the push rod is located on the left side of the exit of the first transport tube 21. When the tennis ball is transported into the launch tube 31, the push rod pushes the tennis ball to move to the right so that the tennis ball is transported to the positioning cavity of the first launch member 32.

[0046] It is worth noting that the push rod can be driven by a motor, mutually meshing gears and racks. The motor is arranged on the mounting frame 5, and the rack is connected to the push rod, so that the motor drives the gear and rack to mesh and drive the push rod to move in the launch tube 31.

[0047] In some embodiments, the six-wheel tennis transmitter 100 further includes a camera assembly 7, a control assembly and a signal transmission assembly 6. The camera assembly 7 and the signal transmission assembly 6 are both arranged on the transmitting assembly 3. The camera assembly 7 is used to shoot the game environment. The camera assembly 7 is connected to the signal transmission assembly 6 so that the data shot by the camera assembly 7 can be transmitted through the signal transmission assembly 6.
