Description

Technical Field

[0001] This utility model relates to the field of training aids technology, specifically to a cyclic lifting and lowering training device for swinging a racket to hit a ball. Background Technology

[0002] With the increasing popularity of racket-based ball sports such as badminton, table tennis, and pickleball, enthusiasts are no longer satisfied with training only in clubs or with a practice partner. They need a personal training tool that is not limited by time, location, or partners, allowing them to conduct repetitive and specialized hitting exercises anytime.

[0003] Existing height-adjustable training devices, such as the badminton training device with automatic retraction and release function described in patent publication number CN221155315U, use a micro geared motor to drive a reel to wind an elastic rope to achieve the function of raising, lowering, and releasing the badminton shuttlecock. However, the above-mentioned training devices have the following defects when in use: after the elastic rope is fully retracted or fully released, the micro geared motor cannot stop working automatically in time because the user does not notice it in time. The continuous winding of the reel causes the shuttlecock at the end of the elastic rope to fall off due to force, or the continuous unwinding of the reel causes it to spin idly, affecting the normal operation and service life of the training device and causing inconvenience to the user. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a cyclic lifting and lowering training device for swinging a ball. When the reel is unwound downwards, the elastic rope on the reel is continuously released downwards to its maximum length. Then, the elastic rope is wound back onto the reel in the opposite direction, realizing the cyclic lifting and lowering control of the ball. Furthermore, it can automatically sense whether the elastic rope is in a fully retracted state and control the micro motor to automatically stop working in time, avoiding the ball at the end of the elastic rope from falling off due to force caused by the continuous winding of the reel. It is convenient for users to use, ensures the normal and smooth use of the training device, and improves the convenience of users.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a cyclic lifting training device for swinging a racket to hit a ball, including a training device shell. A receiving groove is formed on the front of the training device shell, and a reel is rotatably installed in the receiving groove. A micro motor is installed inside the training device shell, and the output end of the micro motor is drivenly connected to the reel. An elastic rope is connected to the outside of the reel and can be wound around the outside of the reel. A through groove is opened at the lower part of the front of the training device shell, and the free end of the elastic rope passes downward through the through groove and is connected to a ball. The training device housing is equipped with a Hall sensor and a control system. The Hall sensor is located at the upper part of the through slot. A sliding member with a shape adapted to the through slot is slidably installed in the through slot. A magnetic component is installed inside the sliding member. The sliding member slides down to the lower part of the through slot under its own gravity and partially extends out from the bottom of the through slot. When the elastic rope wound on the outside of the reel is in the downward unwinding state, the elastic rope on the reel continues to be released downward to its maximum length, and then the elastic rope is wound back onto the reel in the opposite direction. When the elastic rope on the outside of the reel is fully wound up, the ball pushes the slider upward, and the slider slides upward in the through groove. The Hall sensor senses the magnetic element in the slider and transmits the sensing data to the control system, which then controls the micro motor to stop operating.

[0006] A further improvement is that the reel includes a shaft and limiting discs located at both ends of the shaft, and one end of the elastic rope is connected to the outside of the shaft.

[0007] During operation, under the limiting action of the limiting discs at both ends of the rotating shaft, the micro motor drives the rotating shaft and the limiting discs to rotate simultaneously, and the elastic rope can be smoothly wound up to the outside of the rotating shaft, or smoothly unwound downwards from the outside of the rotating shaft.

[0008] A further improvement is that a connecting post is provided between the limiting discs at both ends of the rotating shaft. The connecting post is arranged side by side with the limiting discs. An installation groove is opened in the middle of the outer end of the connecting post, and one end of the elastic rope is sleeved and connected to the installation groove.

[0009] In use, one end of the elastic rope is connected to the mounting groove on the connecting post, and the other end of the elastic rope passes downward through the slot and is connected to the ball. When the reel unwinds downward, the micro motor drives the connecting post between the shaft and the limit plate to rotate synchronously. The elastic rope wound on the outside of the shaft is continuously released downward to its maximum length. Then, the elastic rope can be wound back in the opposite direction to the outside of the shaft, realizing the cyclic lifting and lowering control of the ball. By setting one end of the elastic rope in the mounting groove on the connecting post, the smooth reverse winding of the elastic rope to the outside of the shaft is ensured, avoiding jamming when the elastic rope is wound in the opposite direction.

[0010] A further improvement is that a magnetic component is installed on the upper part of the sliding component, and two limiting components are symmetrically arranged on the outer side of the upper part of the sliding component. The inner sidewall of the through groove is provided with a vertical limiting groove that cooperates with the limiting components.

[0011] By cooperating with the limiting part on the upper part of the slider and the vertical limiting groove on the inner side wall of the through groove, the slider is prevented from detaching from the through groove under its own weight. When the ball pushes the slider upward, the restriction of the vertical limiting groove ensures that the Hall sensor can detect the magnetic part inside the slider, while also preventing the slider from being pushed upward from the through groove.

[0012] A further improvement is that a battery compartment is provided on the training device housing, and a battery cover is provided on the front of the battery compartment. The battery compartment transmits battery power to the control system and the micro motor.

[0013] A further improvement is that the control system is connected to an infrared receiver, which transmits infrared signals via a remote controller to remotely control the micro motor to rotate in the forward or reverse direction.

[0014] During operation, the remote control emits an infrared signal, which is received by the infrared receiver. The receiver then sends a command signal to the controller, which in turn transcodes the command signal to control the operation of the micro motor. For example, the micro motor can be started to drive the reel to rotate forward or backward, causing the elastic rope on the reel to be wound upward directly, or the elastic rope on the reel can be continuously released downward to its maximum length and then wound back onto the reel in the opposite direction, thus achieving the cyclic lifting and lowering control of the sphere. During the above process, the micro motor can be stopped by using the pause button on the remote control to control the length of the elastic rope exposed outside the training device.

[0015] A further improvement is that the training device housing is equipped with a working indicator light and a charging port.

[0016] When the miniature motor is working, the indicator light will illuminate, allowing users to easily understand its operating status. The trainer can be charged via the charging port, making it even more convenient to use.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) In this utility model, when the micro motor drives the reel to unwind downwards, the elastic rope on the reel is continuously released downwards to its maximum length. Then the elastic rope is wound back up onto the reel in the opposite direction, realizing the cyclic lifting and lowering control of the ball. It can also automatically sense whether the elastic rope is in a fully wound state and control the micro motor to stop working in time, avoiding the ball at the end of the elastic rope from falling off due to the continuous winding of the reel. It is convenient for users to use, ensures the normal and smooth use of the trainer, and improves the convenience of users.

[0018] (2) The sliding member, which is slidably set in the through groove, cooperates with the Hall sensor. In normal state (except when the elastic rope is fully wound up), the sliding member slides down to the lower part of the through groove under its own gravity and partially extends out from the bottom of the through groove. At this time, the magnetic element in the sliding member is not in the sensing area of ​​the Hall sensor. The micro motor works normally and drives the reel to rotate in the forward or reverse direction. The elastic rope on the reel is released downward or wound upward. When the elastic rope on the outside of the reel is fully wound up, the ball pushes the bottom end of the sliding member upward. The sliding member slides upward in the through groove. The Hall sensor senses the magnetic element in the sliding member and transmits the sensing data to the control system. The control system controls the micro motor to stop running to avoid the situation where the ball at the end of the elastic rope falls off due to the force of the reel continuing to rotate.

[0019] (3) One end of the elastic rope is connected to the mounting groove on the connecting column, and the other end of the elastic rope passes down through the through groove and is connected to the ball. When the reel is unwound downwards, the micro motor drives the connecting column between the rotating shaft and the limit plate to rotate synchronously. The elastic rope wound on the outside of the rotating shaft is continuously released downwards to the maximum length. Then the elastic rope can be wound in the opposite direction to the outside of the rotating shaft to realize the cyclic lifting control of the ball. By setting one end of the elastic rope in the mounting groove on the connecting column, the elastic rope is smoothly wound in the opposite direction to the outside of the rotating shaft, avoiding jamming when the elastic rope is wound in the opposite direction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] An embodiment of this utility model discloses a cyclic lifting and lowering training device for swinging a racket to hit a ball, such as... Figures 1 to 5 As shown, the device includes a training device housing 1. A receiving groove 4 is formed on the front of the training device housing 1. A reel 10 is rotatably installed in the receiving groove 4. A micro motor 9 is installed inside the training device housing 1. The output end of the micro motor 9 is connected to the reel 10 for driving. An elastic rope 15 is connected to the outside of the reel 10. The elastic rope 15 can be wound around the outside of the reel 10. A through groove 5 is opened at the lower part of the front of the training device housing 1. The free end of the elastic rope 15 passes through the through groove 5 and is connected to a ball 16. The ball 16 is a badminton shuttlecock, table tennis ball, pickle ball, or other ball that is hit by a racket. The training device housing 1 is equipped with a Hall sensor 2 and a control system 3. The Hall sensor 2 is located at the upper part of the through groove 5. A sliding member 7 that matches its shape is slidably installed in the through groove 5. A magnetic component is installed inside the sliding member 7. The sliding member 7 slides down to the lower part of the through groove 5 under its own gravity and partially protrudes from the bottom of the through groove 5. When the elastic rope 15 wound around the outside of the reel 10 is in the downward unwinding state, the elastic rope 15 on the reel 10 continues to release downward to its maximum length, and then the elastic rope 15 is wound back onto the reel 10 in the opposite direction. When the elastic rope 15 on the outside of the reel 10 is fully wound up, the ball 16 pushes the slider 7 upward, and the slider 7 slides upward in the through groove 5. The Hall sensor 2 senses the magnetic element in the slider 7 and transmits the sensing data to the control system 3. The control system 3 controls the micro motor 9 to stop running.

[0024] In this training device, one end of the elastic rope 15 is connected to the reel 10, and the other end of the elastic rope 15 passes downward through the through groove 5 and is connected to a ball 16. When the reel 10 is unwound downward by the micro motor 9, the elastic rope 15 on the reel 10 is continuously released downward to its maximum length. Then the elastic rope 15 is wound back onto the reel 10 in the opposite direction, realizing the cyclic lifting and lowering control of the ball 16. It can also automatically sense whether the elastic rope 15 is in a fully retracted state and control the micro motor 9 to stop working in time to prevent the ball 16 at the end of the elastic rope 15 from falling off due to force caused by the continuous winding of the reel 10. It is convenient for users to use, ensures the normal and smooth use of the training device, and improves the convenience of users. The sliding member 7, which is slidably set in the through groove 5, cooperates with the Hall sensor 2. In normal state (except when the elastic rope 15 is fully wound up), the sliding member 7 slides down to the lower part of the through groove 5 under its own gravity and partially extends out from the bottom of the through groove 5. At this time, the magnetic element in the sliding member 7 is not in the sensing area of ​​the Hall sensor 2. The micro motor 9 works normally and drives the reel 10 to rotate in the forward or reverse direction. The elastic rope 15 on the reel 10 is released downward or wound upward. When the elastic rope 15 on the outside of the reel 10 is fully wound up, the ball 16 pushes the bottom end of the sliding member 7 upward. The sliding member 7 slides upward in the through groove 5. The Hall sensor 2 senses the magnetic element in the sliding member 7 and transmits the sensing data to the control system 3. The control system 3 controls the micro motor 9 to stop running to avoid the situation where the ball 16 at the end of the elastic rope 15 falls off due to force if the reel 10 continues to rotate.

[0025] Among them, such as Figure 1 As shown, the reel 10 includes a rotating shaft 12 and limiting discs 11 located at both ends of the rotating shaft 12. One end of the elastic rope 15 is connected to the outside of the rotating shaft 12. During operation, under the limiting action of the limiting discs 11 at both ends of the rotating shaft 12, the micro motor 9 drives the rotating shaft 12 and the limiting discs 11 to rotate simultaneously. The elastic rope 15 can be smoothly wound up to the outside of the rotating shaft 12, or smoothly unwound downwards from the outside of the rotating shaft 12.

[0026] Specifically, a connecting post 13 is provided between the limiting disks 11 at both ends of the rotating shaft 12. The connecting post 13 is located near the outside of the limiting disk 11 and is arranged side by side with the limiting disk 11. An installation groove 14 is provided in the middle of the outer end of the connecting post 13, and one end of the elastic rope 15 is sleeved and connected to the installation groove 14.

[0027] In use, one end of the elastic rope 15 is connected to the mounting groove 14 on the connecting post 13, and the other end of the elastic rope 15 passes downward through the through groove 5 and is connected to the ball 16. When the reel 10 unwinds downward, the micro motor 9 drives the connecting post 13 between the rotating shaft 12 and the limiting plate 11 to rotate synchronously. The elastic rope 15 wound on the outside of the rotating shaft 12 is continuously released downward to its maximum length. Then, the elastic rope 15 can be wound back in the opposite direction to the outside of the rotating shaft 12, realizing the cyclic lifting and lowering control of the ball 16. By setting one end of the elastic rope 15 in the mounting groove 14 on the connecting post 13, the smooth reverse winding of the elastic rope 15 to the outside of the rotating shaft 12 is ensured, and jamming during reverse winding of the elastic rope 15 is avoided.

[0028] Among them, such as Figure 3 and Figure 6 As shown, a magnetic component is installed on the upper part of the slider 7, and two limiting components 8 are symmetrically arranged on the outer side of the upper part of the slider 7. The inner wall of the through groove 5 is provided with a vertical limiting groove 6 that cooperates with the limiting components 8. Through the cooperation of the limiting component 8 on the upper part of the slider 7 and the vertical limiting groove 6 on the inner wall of the through groove 5, the slider 7 is prevented from detaching from the through groove 5 under its own weight. When the ball 16 pushes the slider 7 upward, the restriction of the vertical limiting groove 6 ensures that the Hall sensor 2 can sense the magnetic component in the slider 7, and also prevents the slider 7 from being pushed upward from the through groove 5.

[0029] The training device housing 1 has a battery compartment, and the front of the battery compartment has a battery cover 17. The battery compartment transmits battery power to the control system 3 and the micro motor 9.

[0030] The control system 3 is connected to an infrared receiver. It transmits infrared signals via a remote control to remotely control the micro-motor 9 to rotate forward or backward. During operation, the remote control transmits infrared signals, which the receiver receives and sends a command signal to the controller. The controller then transcodes the command signal to control the micro-motor 9. For example, it controls the micro-motor 9 to start and drive the reel 10 to rotate forward or backward, causing the elastic rope 15 on the reel 10 to be wound upwards directly, or to continuously release the elastic rope 15 downwards to its maximum length and then wind it back up onto the reel 10 in the opposite direction. This achieves the cyclical lifting and lowering control of the sphere 16. During this process, the micro-motor 9 can be stopped using the pause button on the remote control, controlling the length of the elastic rope 15 exposed outside the training device.

[0031] The trainer housing 1 is equipped with a working indicator light 18 and a charging port 19. When the micro motor 9 is working, the working indicator light 18 will illuminate, allowing the user to easily understand the working status of the micro motor 9. The charging port 19 allows the trainer to be charged, making it more convenient to use.

[0032] The top of the trainer housing 1 is provided with a mounting component for installing the trainer. The mounting component can be a hook or an adhesive hook, or other components with a mounting and positioning structure.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
