Description

Technical Field

[0001] This utility model relates to the field of training aids, specifically to a height-adjustable 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 device has 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, causing the reel to spin idly, which in turn causes the elastic rope to wind in the opposite direction, 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 height-adjustable training device for swinging a racket to hit a ball. It can automatically sense whether the elastic rope is in a fully retracted or fully extended state and control the micro motor to stop working in time. This avoids situations where the ball at the end of the elastic rope is forced off due to continuous winding of the reel, or where the reel spins freely due to continuous unwinding, or where the elastic rope winds in the opposite direction. 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 height-adjustable 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 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 contains 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 element is installed inside the sliding member. Under its own gravity, the sliding member slides downward to the lower part of the through slot and partially extends out from the bottom of the through slot. When the elastic rope on the outside of the reel is in a fully wound state, the ball pushes the sliding member upward. The sliding member slides upward in the through slot. The Hall sensor senses the magnetic element inside the sliding member and transmits the sensing data to the control system. The control system 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 the elastic rope is wound around the outside of the shaft.

[0007] During operation, under the limiting action of the limiting discs at both ends of the rotation, the micro motor drives the rotating shaft to rotate, 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 the rotating shaft has a mounting groove, in which a positioning element is rotatably mounted. The end of the elastic rope is connected to the free end of the positioning element, and the free end of the positioning element is provided with a magnetic element. When the elastic rope on the outside of the reel is in a fully extended state, the elastic rope pulls the positioning element to rotate, and its free end extends downward. The Hall sensor senses the magnetic element in the positioning element and transmits the sensing data to the control system, which then controls the micro motor to stop operating.

[0009] First, during normal winding or unwinding, the positioning element is wound into the mounting slot located outside the rotating shaft under the pull of the elastic cord. When the micro motor controls the elastic cord to be fully unwound, the elastic cord pulls the positioning element downwards, causing its free end to move away from the outer side of the rotating shaft. The free end of the positioning element extends downwards, and the Hall sensor detects the magnetic component inside the free end of the positioning element, transmitting the data to the control system. The control system then stops the micro motor, and the elastic cord is fully unwound, preventing the reel from spinning freely or the elastic cord from winding backwards. During normal operation, the micro motor receives a signal, stops operating in that direction, and reverses direction for one second before stopping. At this time, the magnetic component inside the free end of the positioning element disengages from the Hall sensor's sensing area.

[0010] A further improvement is that the positioning element is an arc-shaped plate, and the outer side of the arc-shaped plate matches the curvature of the outer side of the rotating shaft.

[0011] With the above settings, during normal winding or unwinding, the positioning component is wound into the mounting groove located on the outside of the shaft under the pulling action of the elastic rope. This ensures the integrity and smoothness of the outer side of the shaft, and prevents the formation of protrusions or grooves on the outside of the shaft, thus ensuring that the elastic rope can be smoothly wound to the outside of the shaft.

[0012] A further improvement is that a connecting rod is provided inside one end of the arc-shaped plate, and the two ends of the connecting rod are respectively rotatably mounted on the two limiting discs. A magnetic component is provided inside the other end of the arc-shaped plate, and a slot is provided for the end of the elastic rope to pass through and connect.

[0013] During operation, one end of the arc-shaped plate is rotatably mounted in the mounting groove, and the other end of the arc-shaped plate is connected to an elastic rope. When the elastic rope is initially wound up, the winding action of the elastic rope can smoothly drive the arc-shaped plate to rotate and be stored inward in the mounting groove located outside the rotating shaft. When the elastic rope is fully unwound, the elastic rope can smoothly pull the positioning component to rotate downward. The free end of the positioning component moves away from the outer side of the rotating shaft and extends downward. Through the above structural design, the resistance of the arc-shaped plate during the above actions is reduced, ensuring the smooth progress of the above actions.

[0014] A further improvement is that a magnetic component is installed on the upper part of the sliding member, and a limiting component is provided on the outer side of the upper part of the sliding member, and a limiting protrusion is provided on the inner side wall of the through groove to cooperate with the limiting component.

[0015] The sliding component is prevented from detaching from the through groove by the cooperation of the limiting part on the upper part of the sliding component and the limiting protrusion on the inner wall of the through groove.

[0016] 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.

[0017] 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.

[0018] 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 released or wound up. The micro motor can be stopped to control the length of the elastic rope exposed outside the trainer.

[0019] A further improvement is that the training device housing is equipped with a working indicator light and a charging port.

[0020] 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.

[0021] Compared with the prior art, the present invention has the following beneficial effects: (1) The training device in this utility model can automatically sense whether the elastic rope is fully retracted or fully extended, and control the micro motor to stop working in time to avoid the situation where the ball at the end of the elastic rope falls off due to force caused by the continuous winding of the reel, the continuous unwinding of the reel causes it to spin idly and the elastic rope to wind in the opposite direction. It is convenient for users to use, ensures the normal and smooth use of the training device, and improves the convenience of users.

[0022] (2) When the sliding member is slidably set in the through groove and cooperates with the Hall sensor, in the normal winding or unwinding state, 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 in the fully wound state, 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 force caused by the continuous rotation of the reel.

[0023] (3) By rotating the positioning component set in the mounting groove and cooperating with the Hall sensor, during normal winding or unwinding, the positioning component is wound or unwound into the mounting groove located outside the rotating shaft under the pulling action of the elastic rope. When the micro motor controls the elastic rope to be in the fully unwound state, the elastic rope pulls the positioning component to rotate downward, and the free end of the positioning component moves away from the outer side of the rotating shaft. The free end of the positioning component extends downward, and the Hall sensor senses the magnetic component in the free end of the positioning component and transmits the sensing data to the control system. The control system controls the micro motor to stop running, and the elastic rope is in the fully unwound state, so there will be no situation of the reel spinning idly or the elastic rope winding in the opposite direction. During normal operation, the micro motor will stop running in this direction when it receives the signal and run in the opposite direction for 1 second before stopping. At this time, the magnetic component in the free end of the positioning component is removed from the sensing area of ​​the Hall sensor. Attached Figure Description

[0026] 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.

[0027] An embodiment of this utility model discloses a height-adjustable training device for swinging a racket to hit a ball, such as... Figures 1 to 4 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 9 is rotatably installed in the receiving groove 4. A micro motor 8 is installed inside the training device housing 1. The output end of the micro motor 8 is connected to the reel 9 for driving. An elastic rope 16 is wound around the outside of the reel 9. 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 16 passes through the through groove 5 and is connected to a ball 17. The ball 17 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 6 with a shape adapted to the through groove 5 is slidably installed in the through groove 5. A magnetic component is installed inside the sliding member 6. Under its own gravity, the sliding member 6 slides down to the lower part of the through groove 5 and partially extends out from the bottom of the through groove 5. When the elastic rope 16 on the outside of the reel 9 is in a fully wound state, the ball 17 pushes the sliding member 6 upward. The sliding member 6 slides upward in the through groove 5. The Hall sensor 2 senses the magnetic component inside the sliding member 6 and transmits the sensing data to the control system 3. The control system 3 controls the micro motor 8 to stop running.

[0028] This trainer can automatically sense whether the elastic rope 16 is fully retracted or fully extended, and control the micro motor 8 to stop working in time. This prevents the ball 17 at the end of the elastic rope 16 from falling off due to force caused by the continuous winding of the reel 9, the continuous unwinding of the reel 9 causing it to spin freely, and the elastic rope 16 from winding in the opposite direction. It is convenient for users to use, ensures the normal and smooth use of the trainer, and improves the convenience of users. During operation, the sliding member 6, which is slidably set in the through groove 5, cooperates with the Hall sensor 2. In the normal winding or unwinding state, the sliding member 6 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. At this time, the magnetic element in the sliding member 6 is not in the sensing area of ​​the Hall sensor 2. The micro motor 8 works normally, driving the reel 9 to rotate in the forward or reverse direction. The elastic rope 16 on the reel 9 is released downward or wound upward. When the elastic rope 16 on the outside of the reel 9 is in the fully wound state, the ball 17 pushes the bottom end of the sliding member 6 upward. The sliding member 6 slides upward in the through groove 5. The Hall sensor 2 senses the magnetic element in the sliding member 6 and transmits the sensing data to the control system 3. The control system 3 controls the micro motor 8 to stop running to avoid the situation where the reel 9 continues to rotate, causing the ball 17 at the end of the elastic rope 16 to fall off due to force.

[0029] Among them, such as Figure 5 and Figure 7 As shown, the reel 9 includes a rotating shaft 10 and limiting discs 11 located at both ends of the rotating shaft 10. The elastic rope 16 is wound around the outside of the rotating shaft 10. During operation, under the limiting action of the limiting discs 11 at both ends of the rotating shaft, the micro motor 8 drives the rotating shaft 10 to rotate, and the elastic rope 16 can be smoothly wound to the outside of the rotating shaft 10 in a directional manner, or smoothly unwound downwards from the outside of the rotating shaft 10 in a directional manner.

[0030] like Figures 5 to 9As shown, a mounting groove 12 is provided on the rotating shaft 10, and a positioning element 13 is rotatably arranged in the mounting groove 12. The end of the elastic rope 16 is connected to the free end of the positioning element 13, and a magnetic element is provided at the free end of the positioning element 13. When the elastic rope 16 on the outside of the reel 9 is in the fully extended state, the elastic rope 16 pulls the positioning element 13 to rotate, and its free end extends downward. The Hall sensor 2 senses the magnetic element in the positioning element 13 and transmits the sensing data to the control system 3. The control system 3 controls the micro motor 8 to stop running.

[0031] First, during normal winding or unwinding, the positioning member 13 is wound or unwound into the mounting groove 12 located outside the rotating shaft 10 under the pulling action of the elastic rope 16 (e.g., Figure 9 As shown), when the micro motor 8 controls the elastic rope 16 to be in the fully extended state, the elastic rope 16 pulls the positioning member 13 to rotate downwards, and the free end of the positioning member 13 moves away from the outer side of the rotating shaft 10, and the free end of the positioning member 13 extends downwards (as shown). Figure 5 As shown, Hall sensor 2 senses the magnetic element inside the free end of positioning element 13 and transmits the sensing data to control system 3. Control system 3 controls micro motor 8 to stop operating, and elastic rope 16 is in a fully unwound state, preventing the reel 9 from spinning idly and the elastic rope 16 from winding in the opposite direction. During normal operation, micro motor 8 receives a signal, stops operating in that direction, and reverses its direction for 1 second before stopping. At this time, the magnetic element inside the free end of positioning element 13 disengages from the sensing area of ​​Hall sensor 2.

[0032] Specifically, the positioning element 13 is an arc-shaped plate, and the outer side of the arc-shaped plate matches the curvature of the outer side of the rotating shaft 10. With the above setting, in the normal winding or unwinding state, the positioning element 13 is wound into the mounting groove 12 located on the outer side of the rotating shaft 10 under the pulling action of the elastic rope 16, which can ensure the integrity and smoothness of the outer side of the rotating shaft 10, and will not form a protrusion or groove structure on the outer side of the rotating shaft 10, ensuring that the elastic rope 16 can be smoothly wound to the outer side of the rotating shaft 10.

[0033] A connecting rod 14 is provided inside one end of the arc-shaped plate. The two ends of the connecting rod 14 are respectively rotatably mounted on two limiting discs 11. A magnetic component is provided inside the other end of the arc-shaped plate, and a slot 15 is provided for the end of the elastic rope 16 to pass through and connect. During operation, one end of the arc-shaped plate is rotatably mounted in the mounting groove 12, and the other end of the arc-shaped plate is connected to the elastic rope 16. When the elastic rope 16 is initially wound up, the winding action of the elastic rope 16 can smoothly drive the arc-shaped plate to rotate and be stored inward in the mounting groove 12 located outside the rotating shaft 10. When the elastic rope 16 is completely unwound, the elastic rope 16 can smoothly pull the positioning component 13 to rotate downward. The free end of the positioning component 13 moves away from the outer side of the rotating shaft 10 and extends downward. Through the above structural design, the resistance of the arc-shaped plate during the above actions is reduced, ensuring the smooth operation of the above actions.

[0034] Among them, such as Figure 4 As shown, a magnetic component is installed on the upper part of the slider 6, and a limiting component 7 is provided on the outer side of the upper part of the slider 6. The inner wall of the through groove 5 is provided with a limiting protrusion that cooperates with the limiting component 7. Through the cooperation of the limiting component 7 on the upper part of the slider 6 and the limiting protrusion on the inner wall of the through groove 5, the slider 6 is prevented from detaching from the through groove 5 under its own gravity.

[0035] The training device housing 1 has a battery compartment with a battery cover 18 on the front. The battery compartment transmits battery power to the control system 3 and the micro motor 8. The control system 3 is connected to an infrared receiver and remotely controls the micro motor 8 to rotate forward or backward by emitting infrared signals via a remote controller. During operation, the remote controller emits infrared signals, which are received by the infrared receiver, which then sends a command signal to the controller. The controller receives the command signal, transcodes it, and controls the micro motor 8 to run. For example, it controls the micro motor 8 to start and drive the reel 9 to rotate forward or backward, causing the elastic rope 16 on the reel 9 to be released or wound up, stopping the micro motor 8, and controlling the length of the elastic rope 16 exposed outside the training device.

[0036] The trainer housing 1 is equipped with a working indicator light 19 and a charging port 20. When the micro motor 8 is working, the working indicator light 19 will light up, allowing the user to easily understand the working status of the micro motor 8. The trainer can be charged through the charging port 20, making it more convenient to use.

[0037] 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.

[0038] 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.
