Description

Technical Field

[0001] The invention belongs to the technical field of sports training auxiliary equipment, and in particular to a device for teaching and training pickleball. Background Art

[0002] Pickleball is a thin-shell hollow ball made of hard plastic with 26 holes about 1 cm in diameter. In terms of the amount of physical activity and mobility, pickleball is more active than table tennis, and is suitable for people of all ages, especially those who used to play tennis but have lost the conditions to continue playing tennis or badminton, or those who are older and like to play tennis, table tennis, or badminton. If you want to find a more interesting alternative sport, pickleball is an excellent choice. In addition, the venue and equipment required for pickleball are cheaper than those for tennis.

[0003] Due to its own advantages, pickleball has been loved by more and more people. In the traditional teaching and training of pickleball, the construction of the fence of the pickleball field will increase the construction expenses of the field, so some fields do not have fences. Unlike badminton, pickleball stays in place after landing. Pickleball is round and elastic. After landing, it will continue to bounce and roll, causing the landing points to be very scattered and far away. Athletes will waste a lot of time in the process of picking up the ball, which will have a huge delay effect on the efficiency of teaching and training. Especially for beginners, the probability of receiving the ball is low, so students need to pick up the ball frequently, which affects the training efficiency and enthusiasm of the students, so it needs to be improved. It will be a good solution to improve the serving efficiency by automatically launching pickleballs through a serving machine, and to improve the efficiency of picking up balls by automatically collecting fences.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0029] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] Please refer to Figure 1-8As shown, a pickleball teaching and training device provided in this embodiment includes a floor 1, a serving machine 2 is fixedly installed on the left side of the middle part of the top of the floor 1, a supporting leg 3 is fixedly installed on the rear side of the top of the floor 1, the number of the supporting legs 3 is five, and a track 4 is fixedly installed on the top of the five supporting legs 3. The left side of the front end of the track 4 is fixedly connected to the rear end of the serving machine 2, a ball gathering net 5 located on the right side of the track 4 is fixedly installed on the front and rear ends of the right side of the top of the floor 1, a ball gathering net 5 is fixedly installed on the bottom end of the ball gathering net 5, a ball falling tube 7 located directly above the track 4 is fixedly installed in the middle of the bottom end of the ball net collecting bag 6, a bracket 8 is fixedly installed in the middle of the left end of the ball falling tube 7, and the bottom end of the bracket 8 is fixedly connected to the top of the floor 1.

[0032] When using the pickle ball teaching and training device of the present invention, the student stands between the serving machine 2 and the ball gathering net 5, and the serving machine 2 serves the pickle ball, and the student practices the catching of the pickle ball. Since the serving machine 2 can automatically adjust the serving direction, angle and speed of the pickle ball according to the student's proficiency in catching the ball and the actual needs of the student, serving the ball through the serving machine 2 can train the student's catching reaction ability when facing pickle balls of different directions, angles and speeds, thereby strengthening the student's catching ability and improving the student's ability to cope with pickle balls in different states. When the student fails to catch the pickle ball successfully, the pickle ball will continue to move backward, and the existence of the ball gathering net 5 will block and intercept the pickle ball missed by the student. At the same time, since the ball gathering net 5 adopts an inclined design, when the pickle ball hits the ball gathering net 5, the interaction of the inclined design of the ball gathering net 5 and the elastic force of the ball gathering net 5 itself will slow down the pickle ball. The pickle ball that has lost its impact and power will automatically roll and slide into the ball collecting bag 6 along the outer surface of the ball collecting net 5 under the action of gravity. Because the ball collecting bag 6 adopts a conical design, the pickle ball that falls into the ball collecting bag 6 will continue to move along the inner surface of the ball collecting bag 6 under the action of its own gravity, and then enter the groove at the top of the track 4 through the ball dropping tube 7. The depth of the groove at the top of the track 4 is two-thirds of the diameter of the pickle ball, and the width of the groove at the top of the track 4 is greater than the diameter of the pickle ball. Therefore, the pickle ball that falls into the track 4 will roll along the track 4 to the serving machine 2, and finally enter the interior of the serving machine 2, waiting for the next serve of the serving machine 2. This cycle is repeated, and the automatic recovery of missed pickle balls can be realized, so that students do not need to pick up balls frequently, thereby improving the training efficiency of students and the enthusiasm of students for pickle ball training.

[0033] At the same time, a driving motor 9 is fixedly installed on the front right side of the bottom end of the track 4, and a driving shaft 10 is fixedly sleeved on the other end of the output shaft of the driving motor 9. The top end of the driving shaft 10 is movably connected to the bottom end of the track 4, and a driving wheel 11 is fixedly sleeved on the top of the outer surface of the driving shaft 10. The top end of the driving wheel 11 is movably connected to the bottom end of the track 4.

[0034] When the drive motor 9 is started, the drive shaft 10 will drive the driving wheel 11 to rotate along the bottom end of the track 4, and the rotation of the driving wheel 11 will provide a stable rotational power. At the same time, the drive motor 9 can realize forward and reverse rotation, so that the driving wheel 11 can realize rotation in both forward and reverse directions.

[0035] In an optional scheme of the above embodiment, a first circular shaft 12 is fixedly installed at the bottom of the right side of the front end of the track 4, and a first circular wheel 13 is movably sleeved on the outer surface of the first circular shaft 12, and the outer surface of the first circular wheel 13 is movably connected to the outer surface of the track 4.

[0036] The outer surface of the first circular shaft 12 and the inner surface of the first circular wheel 13 are both smooth, thereby ensuring that the first circular wheel 13 will not get stuck when rotating along the outer surface of the first circular shaft 12. The mutual cooperation between the first circular shaft 12 and the first circular wheel 13 will play a guiding role in subsequent use, thereby improving the convenience of using the pickle ball teaching and training device.

[0037] In an optional scheme of the above embodiment, a second circular shaft 15 is fixedly installed at the bottom of the left front end of the track 4, and a second circular wheel 16 is movably sleeved on the outer surface of the second circular shaft 15, and the outer surface of the second circular wheel 16 is movably connected to the outer surface of the track 4.

[0038] The outer surface of the second circular shaft 15 and the inner surface of the second circular wheel 16 are both smooth, and the second circular wheel 16, the second circular shaft 15 and the first circular wheel 13, the first circular shaft 12 are all the same in shape and size, thereby ensuring that the second circular wheel 16, the second circular shaft 15 and the first circular wheel 13, the first circular shaft 12 can all play a guiding role.

[0039] In an optional scheme of the above embodiment, a second baffle 17 and a first baffle 14 are fixedly installed on the left and right sides of the top of the track 4, and the first baffle 14 and the second baffle 17 are the same in shape and size; due to the presence of the first baffle 14 and the second baffle 17, it will play a role in blocking and preventing falling off, thereby improving the stability of the pickle ball teaching and training device during use.

[0040] At the same time, a fixed shaft 18 is fixedly installed on the top left side of the front end of the track 4, and a driven wheel 19 is movably sleeved on the outer surface of the fixed shaft 18, and the outer surface of the driven wheel 19 is movably connected to the outer surface of the track 4; the outer surface of the fixed shaft 18 and the inner surface of the driven wheel 19 are both smooth, and the existence of the fixed shaft 18 and the driven wheel 19 will play a role in transmitting power during the use of the pickleball teaching and training device.

[0041] In the optional scheme of the above embodiment, the driven wheel 19 is connected to the second round wheel 16, the first round wheel 13 and the driving wheel 11 through the transmission belt 20, the outer surface of the transmission belt 20 is movably connected to the outer surfaces of the first baffle 14 and the second baffle 17, and the outer surface of the transmission belt 20 is movably connected to the outer surface of the support leg 3; when the driving wheel 11 rotates, under the joint action of the second round wheel 16, the first round wheel 13 and the driven wheel 19, the transmission belt 20 will rotate, and at the same time, the width of the transmission belt 20 is the same as the width of the track 4, so as to ensure that the outer surfaces of the transmission belt 20 and the track 4 are on the same horizontal plane, and the movable connection between the transmission belt 20 and the first baffle 14, the second baffle 17 and the support leg 3 can effectively ensure the stability of the rotation of the transmission belt 20.

[0042] In an optional solution of the above embodiment, a long plate 21 is fixedly installed at the front of the right end of the transmission belt 20, the left end of the long plate 21 is movably connected to the right end of the track 4, and a pneumatic cylinder 22 is fixedly installed at the bottom of the right end of the long plate 21.

[0043] When the transmission belt 20 rotates, the long board 21 will move along the outer surface of the track 4 with the pneumatic cylinder 22, and the movable connection between the long board 21 and the track 4 can ensure the stability of the long board 21 when moving.

[0044] In the optional scheme of the above embodiment, a fixing frame 23 is fixedly installed on the top of the right end of the long board 21, and a round rod 24 is movably sleeved inside the top of the fixing frame 23; due to the existence of the fixing frame 23, it will play a role of fixing and limiting, and the round rod 24 can serve as a rotation axis, and at the same time, a push rod 25 is fixedly sleeved on the outer surface of the round rod 24, and the outer surface of the push rod 25 is movably sleeved on the inner surface of the fixing frame 23, the left side of the bottom end of the push rod 25 is movably connected to the top of the track 4, and the right side of the bottom end of the push rod 25 is hinged with an inclined rod 26, and the other end of the inclined rod 26 is hinged to the top of the pneumatic cylinder 22.

[0045] When the pneumatic cylinder 22 is started, the inclined rod 26 will move, so that the push rod 25 will rotate around the round rod 24 through the inclined rod 26, so that the push rod 25 will be lifted. When the push rod 25 contacts the track 4, the pickle ball inside the groove at the top of the track 4 can be pushed as the long board 21 moves, thereby effectively preventing the pickle ball from being blocked in the groove at the top of the track 4.

[0046] When using the present invention, first, the student stands between the serving machine 2 and the ball gathering net 5 to prepare for the pickle ball catching training. When the student is ready, the serving machine 2 is started, so that the serving machine 2 starts to serve the pickle ball. The serving machine 2 adopts the serving direction, angle and speed of the last training by default. The student can adjust the serving direction, angle and speed of the serving machine 2 according to his own proficiency and the training method he wants. When the student successfully catches the ball and hits it back, the training task is completed. When the student fails to catch the pickle ball, the pickle ball will move toward the ball gathering net 5, thereby hitting the ball gathering net 5. At this time, under the combined effect of the inclined design of the ball gathering net 5 and the elasticity of the ball gathering net 5 itself, the pickle ball will be buffered. The force is unloaded, thereby losing the impact force and the power it carries, so that the pickle ball automatically rolls downward along the outer surface of the ball collecting net 5 under the action of its own gravity. Due to the conical design of the ball net collecting bag 6, the pickle ball that automatically rolls downward will fall into the ball net collecting bag 6, and then continue to roll downward along the inner surface of the ball net collecting bag 6, and then pass through the ball drop tube 7 under the ball net collecting bag 6 and fall into the groove at the top of the track 4, and finally return to the serving machine 2 through the track 4, waiting for the next serve of the serving machine 2. This cycle is repeated, and the automatic recovery of the pickle ball missed by the trainee can be realized, so that the trainee does not need to pick up the ball frequently, thereby improving the trainee's ball catching training efficiency and the trainee's enthusiasm for pickle ball training.

[0047] In the process of the pickle ball passing through the track 4 and returning to the serving machine 2, the driving motor 9 is started, so that the driving shaft 10 drives the driving wheel 11 to rotate. Since the driving wheel 11 and the first round wheel 13, the second round wheel 16, and the driven wheel 19 are connected through the transmission belt 20, as the driving wheel 11 rotates, the transmission belt 20 will rotate under the joint action of the first round wheel 13, the second round wheel 16, and the driven wheel 19. At this time, the long board 21 fixedly connected to the outer surface of the transmission belt 20 will move along the top of the track 4 with the push rod 25. Since the depth of the groove at the top of the track 4 is two-thirds of the diameter of the pickle ball, and the width of the groove at the top of the track 4 is greater than the diameter of the pickle ball, the push rod 25 will push the pickle ball as it moves, thereby ensuring that the pickle ball can be in the groove at the top of the track 4. The interior continues to roll without clogging. When the push rod 25 pushes the pickle ball back to the serving machine 2, the pneumatic cylinder 22 is started, so that the pneumatic cylinder 22 generates a pulling force on the bottom end of the inclined rod 26, pulling the inclined rod 26 to move downward. Because the top end of the inclined rod 26 is hinged to the bottom end of the push rod 25, as the inclined rod 26 moves, the top end of the inclined rod 26 will generate a pulling force on the push rod 25, pulling the push rod 25 to rotate along the inner surface of the fixed frame 23 with the round rod 24 as the axis, thereby lifting the push rod 25, and then starting the drive motor 9 again, so that the transmission belt 20 brings the long board 21 and the push rod 25 back to their original position. This repeated cycle can ensure the continuity of the pickle ball rolling inside the groove at the top of the track 4, and prevent it from being blocked and affecting the normal operation of the pickle ball teaching and training device.

[0048] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
