[0002] When practicing badminton hitting skills, a badminton hitting training device can be used. By hanging a badminton on the hanging rope of the badminton hitting training device, players can repeatedly hit the badminton, eliminating the need for frequent ball picking and throwing. When the training is over, the badminton hitting training device needs to be stored. However, the hanging ropes of existing badminton hanging devices are usually exposed. During handling and storage, the hanging ropes are easily entangled in other places, and if not noticed, the hanging ropes are easily torn off. Therefore, the position of the hanging ropes needs to be constantly monitored, resulting in a poor user experience. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a badminton hitting training device, which can conveniently store the hanging rope, reduce the risk of the hanging rope being entangled, and improve the user experience.

[0004] The badminton hitting training device according to an embodiment of the utility model includes:

[0005] A base;

[0006] A support rod, the lower end of which is connected to the base, and the support rod is a hollow structure;

[0007] A connecting rod, one end of which is connected to the upper end of the support rod, and a first rotating member is provided at the end of the connecting rod away from the support rod;

[0008] An automatic wire rewinder, installed inside the support rod. The automatic wire rewinder includes a hanging rope, a mounting seat, a wire winding wheel, a torsion spring and a button.

[0043] Refer to Figure 1As shown, a badminton hitting training device 1000 according to an embodiment of the present utility model can be used to assist players in training ball games such as badminton 500. Taking the hanging of badminton 500 as an example hereinafter. The badminton hitting training device 1000 according to an embodiment of the present utility model includes: a base 100, a support rod 200, a connecting rod 300, and an automatic wire rewinder 400. The lower end of the support rod 200 is connected to the base 100, and the base 100 serves as a support. The support rod 200 is a hollow structure, which not only reduces the weight but also facilitates the installation of the automatic wire rewinder 400. One end of the connecting rod 300 is connected to the upper end of the support rod 200, and the other end is provided with a first rotating member 310. When the badminton hitting training device 1000 needs to be used, the connecting rod 300 and the support rod 200 are arranged at an angle. Refer to Figure 2 and Figure 3 As shown, the automatic wire rewinder 400 is installed inside the support rod 200. The automatic wire rewinder 400 includes a hanging rope 410, a mounting seat 420, a wire winding wheel 430, a torsion spring 440, and a button 450. The torsion spring 440 is arranged inside the mounting seat 420. The wire winding wheel 430 is rotatably connected to the mounting seat 420 and connected to the torsion spring 440. The torsion spring 440 is configured to provide a restoring force for the wire winding wheel 430 to rotate back. The button 450 is connected to the mounting seat 420 and is configured to control the wire winding wheel 430 to stop rotating or separate from the wire winding wheel 430. One end of the hanging rope 410 is wound around the wire winding wheel 430, and the other end of the hanging rope 410 passes out of the support rod 200 and is wound around the first rotating member 310.

[0044] It can be understood that by setting the support to be connected to the base 100, the base 100 plays a supporting role to prevent the badminton hitting training device 1000 from tipping over. One end of the connecting rod 300 is connected to the upper end of the support rod 200, and a first rotating member 310 is provided at the end of the connecting rod 300 away from the support rod 200. One end of the hanging rope 410 is provided on the first rotating member 310 and can be connected to the badminton 500, table tennis ball, etc. The first rotating member 310 plays a role in reducing the friction when the hanging rope 410 moves, making the pulling of the hanging rope 410 smoother. The function of the connecting rod 300 is to guide the hanging rope 410 to a position away from the support rod 200, preventing the player from accidentally hitting the support rod 200 when hitting the ball, so as to improve safety. The automatic wire rewinder 400 is installed inside the support rod 200, and the hanging rope 410 is wound around the winding wheel 430. Since the winding wheel 430 is connected to the torsion spring 440, when the hanging rope 410 is pulled, the winding wheel 430 is driven to rotate and the torsion spring 440 contracts. After the hanging rope 410 is released, the button 450 abuts against the winding wheel 430 and automatically restricts the rotation of the winding wheel 430, thus preventing the hanging rope 410 from retracting. When it is necessary to store the badminton hitting training device 1000, press the button 450 to separate the button 450 from the winding wheel 430. After losing the restriction, the winding wheel 430 automatically rotates under the restoring force of the torsion spring 440, thereby recycling the hanging rope 410 into the connecting rod 300, preventing the hanging rope 410 from winding around other devices. Therefore, the storage of the hanging rope 410 is relatively simple and convenient, which can improve the user experience.

[0045] Referring to Figure 3 and Figure 4 As shown, in the embodiment of the present invention, along the axial direction of the winding wheel 430, the torsion spring 440 and the button 450 are respectively located at both axial ends of the winding wheel 430 to prevent the button 450 from affecting the movement of the torsion spring 440. The structural layout is reasonable and the reliability is high. A first limiting block 431 is provided on the side of the winding wheel 430 facing the button 450, and a second limiting block 451 is provided on the button 450. The first limiting block 431 can abut against the second limiting block 451 to restrict the rotation of the winding wheel 430.

[0046] For example, referring to Figure 3 and Figure 5As shown, the cross-section of the first limiting block 431 is triangular, and the cross-section of the second limiting block 451 is also triangular. Moreover, the tips of the first limiting block 431 and the second limiting block 451 are arranged oppositely. When the lanyard 410 is pulled, the winding wheel 430 is driven to rotate clockwise, and the tip of the first limiting block 431 rotates towards the tip of the second limiting block 451. Due to problems such as manufacturing precision, assembly precision, and vibration, the tip of the first limiting block 431 will not exactly align with the tip of the second limiting block 451. Therefore, the first limiting block 431 can continue to rotate past the second limiting block 451, that is, the winding wheel 430 is basically not hindered when rotating clockwise.

[0047] After the lanyard 410 is released, the winding wheel 430 rotates in reverse under the action of the torsion spring 440, that is, rotates counterclockwise. One end of the first limiting block 431 away from the tip is called the flat end, that is, the flat ends of the first limiting block 431 and the second limiting block 451 can abut against each other, thereby restricting the winding wheel 430 from continuing to rotate counterclockwise to prevent the winding wheel 430 from taking up the line.

[0048] By adopting the above scheme, the button 450 can automatically limit the counterclockwise rotation of the winding wheel 430, and at the same time does not hinder the clockwise rotation of the winding wheel 430, which is beneficial for the user to adjust the position of the lanyard 410, thereby simplifying the user operation, improving the use experience, having a simple structure, and being reasonably and reliably designed.

[0049] Refer to Figure 3 and Figure 4As shown, in the embodiment of the present utility model, the mounting base 420 includes a bottom shell 421 and a cover 422 which are connected to each other. The bottom shell 421 and the cover 422 are cylindrical. An installation cavity 423 is formed between the bottom shell 421 and the cover 422. The wire winding wheel 430 and the torsion spring 440 are both arranged in the installation cavity 423. A through hole 424 communicating with the installation cavity 423 is provided on the end wall of the cover 422. An opening 426 is provided on the side wall of the cover 422. The opening 426 and the through hole 424 are arranged at intervals. The hanging rope 410 can pass through the opening 426. The bottom shell 421 is provided with a first rotating shaft 425. The first rotating shaft 425 is of a hollow structure. The wire winding wheel 430 is rotatably connected to the first rotating shaft. The automatic retractor 400 further includes an elastic member 460. The elastic member 460 can be a spring, an elastic rubber member or a silica gel member, etc. The elastic member 460 is arranged inside the first rotating shaft 425. The button 450 includes a limiting portion 452 and a rod portion 453 which are connected to each other. The limiting portion 452 is located in the installation cavity 423 and is connected to the first rotating shaft 425. And there is no relative rotation between the limiting portion 452 and the first rotating shaft 425, that is, the limiting portion 452 can only move along the axial direction of the first rotating shaft 425 and cannot rotate circumferentially along the limiting portion 452. The rod portion 453 passes through the through hole 424. The elastic member 460 is configured to provide an elastic force that abuts against the inner wall of the cover 422 to the limiting portion 452. When the rod portion 453 is pressed, the button 450 moves in the direction close to the wire winding wheel 430, and the second limiting block 451 and the first limiting block 431 are separated. The wire winding wheel 430 can rotate counterclockwise under the action of the torsion spring 440. When the rod portion 453 is released, the button 450 moves in the direction away from the wire winding wheel 430, and the second limiting block 451 can abut against the first limiting block 431. Therefore, by providing the elastic member 460, the button 450 can be reset to realize the stopping rotation of the wire winding wheel 430.

[0050] Referring to Figure 3 As shown, in the embodiment of the present utility model, the wire winding wheel 430 includes a base plate 432 and an annular plate 433. The base plate 432 is circular. The annular plate 433 is circumferentially connected to the outer edge of the base plate 432. For example, the connection method can be integrally formed. At both ends of the annular plate 433 along the axial direction of the wire winding wheel 430, a plurality of first stoppers 434 and a plurality of second stoppers 435 are respectively provided. The plurality of first stoppers 434 and the plurality of second stoppers 435 are arranged at intervals along the circumferential direction of the wire winding wheel 430 and protrude radially along the wire winding wheel 430. The hanging rope 410 is wound between the first stoppers 434 and the second stoppers 435. Among them, the first stoppers 434 and the second stoppers 435 are used to limit the hanging rope 410 from detaching from the annular plate 433, playing a role in limiting, improving the reliability and stability during winding, and reducing the situation where the hanging rope 410 is wound outside the annular plate 433.

[0051] Since different players have different requirements for the hitting height of the badminton 500, for this reason, referring to Figure 1 、Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , in the embodiment of the present utility model, the support rod 200 includes a first rod section 210 and a second rod section 220. The lower end of the first rod section 210 is connected to the base 100. The lower end of the second rod section 220 is inserted into the upper end of the first rod section 210, and the relative position between the second rod section 220 and the first rod section 210 is adjustable to change the overall height of the support rod 200 to meet the usage requirements of different players. To fix the relative position of the first rod section 210 and the second rod section 220, the badminton hitting training device 1000 further includes a first adjusting member 250. The first adjusting member 250 includes a screw rod section 251 and a knob 252 which are connected. The screw rod section 251 is threadedly connected to the first rod section 210, and the screw rod section 251 can abut against the second rod section 220 to limit the position of the second rod section 220. For example, the second rod section 220 is provided with a guiding groove 314 extending along its axial direction. One end of the screw rod section 251 is disposed in the guiding groove 314 and can abut against the wall surface of the guiding groove 314, thereby limiting the position of the second rod section 220 relative to the first rod section 210. Among them, through the guiding cooperation of the screw rod section 251 and the guiding groove 314, the rotation of the second rod section 220 around the first rod section 210 can be limited to avoid the situation that the connecting rod 300 shakes around randomly.

[0052] In the embodiment of the present utility model, the support rod 200 further includes a third rod section 230. One end of the third rod section 230 is connected to the connecting rod 300, and the other end of the third rod section 230 is inserted into the second rod section 220, and the position between the third rod section 230 and the second rod section 220 is adjustable. The adjustment method is similar to the above method and will not be elaborated here. It can be understood that the heights of both the second rod section 220 and the third rod section 230 can be adjusted. When it is necessary to store the device after training, the second rod section 220 is stored in the first rod section 210, and the third rod section 230 is stored in the second rod section 220, which can shorten the axial dimension of the support rod 200, facilitate the storage and transportation of the badminton hitting training device 1000, and reduce the space occupied by the badminton hitting training device 1000.

[0053] To further reduce the space occupied by the badminton hitting training device 1000 during storage, referring to Figure 8 and Figure 9As shown, in the embodiment of the present utility model, one end of the connecting rod 300 is hinged to the support rod 200. For example, the connecting rod 300 is hinged to the third rod section 230 to adjust the relative positions of the connecting rod 300 and the support rod 200. A clamping portion 330 is provided on one side of the connecting rod 300. The badminton hitting training device 1000 further includes a limiting rod 320. One end of the limiting rod 320 is hinged to the support rod 200, and a notch 321 is provided at the other end of the limiting rod 320. The limiting rod 320 is clamped to the clamping portion 330 through the notch 321 to limit the rotation of the connecting rod 300. When the badminton hitting training device 1000 needs to be stored, the limiting rod 320 and the clamping portion 330 are separated. After losing the support of the limiting rod 320, the connecting rod 300 can automatically fold under the action of gravity to reduce the occupied space of the badminton hitting training device 1000, facilitating storage or transportation.

[0054] In order to reduce the situation where the head of the badminton 500 shakes around during the return process when hitting the badminton 500, referring to Figure 10 As shown, in the embodiment of the present utility model, the first rotating member 310 includes a guide wheel 311 and a second rotating shaft 312. The guide wheel 311 is rotatably connected to the second rotating shaft 312, and the second rotating shaft 312 is fixedly connected to the connecting rod 300. The badminton hitting training device 1000 further includes a guiding portion 313. The guiding portion 313 is connected to the second rotating shaft 312 and a guiding groove 314 is formed between the guiding portion 313 and the guide wheel 311. The hanging rope 410 is threaded through the guiding groove 314, and there is a certain frictional force between the hanging rope 410 and the guiding groove 314 to limit the self-rotation of the hanging rope 410, so that the head of the badminton 500 can return to the initial position during the return process, facilitating the player to hit the ball at a fixed position.

[0055] Since the hanging rope 410 needs to pass through the turning point between the support rod 200 and the connecting rod 300, in order to reduce the situation where the hanging rope 410 is worn and broken, referring to Figure 7 and Figure 8 As shown, in the embodiment of the present utility model, the badminton hitting training device 1000 further includes a second rotating member 240. The second rotating member 240 is rotatably connected to the upper end of the support rod 200, and the hanging rope 410 is wound around the second rotating member 240. The second rotating member 240 includes a roller, and the roller plays a role in guiding and reducing the sliding frictional force of the hanging rope 410.

[0056] Referring to Figure 1As shown, in the embodiment of the present utility model, the base 100 includes a guide sleeve 110, a second adjusting member 120, a plurality of legs 130, and a plurality of connecting rods 140. The guide sleeve 110 is sleeved on the support rod 200 and can slide axially along the support rod 200. The structure of the second adjusting member 120 is similar to that of the first adjusting member 250. The second adjusting member 120 is threadedly connected to the guide sleeve 110 and is configured to fix the position of the guide sleeve 110. The plurality of legs 130 are arranged at intervals along the circumferential direction of the support rod 200. One end of the leg 130 is hinged to the guide sleeve 110, and one end of the connecting rod 140 is hinged to the lower end of the support rod 200, and the other end of the connecting rod 140 is hinged to the corresponding leg 130.
