Description

Technical Field

[0001] The present invention relates to the technology of sports equipment, and particularly to a portable martial arts movement correction device. Background Art

[0002] In martial arts training, especially when practicing arm movements, controlling the extension angle of the elbow joint is crucial to ensure the standardization of movements and avoid sports injuries. Taking the daily character punching in Wing Chun as an example, it is required that the elbow trajectory strictly maintains a straight line (±5° deviation). If the abduction angle is too large, it will lead to the dispersion of strength; while for the elbow strike in Muay Thai, the bending angle of the elbow needs to be limited within the range of 90 - 120°, to prevent ligament injuries caused by hyperextension.

[0003] Traditional martial arts movement correction mainly relies on the oral guidance of coaches or manual assistance for correction, which has problems such as poor real - time performance and lagging feedback. Although existing electronic motion capture devices can provide real - time feedback, they have defects such as high cost, complex wearing, and dependence on external power sources, making it difficult to popularize to daily training scenarios. At the same time, although rigid limiting devices (such as fixed brackets) can limit the movement amplitude, they lack flexible constraints and are prone to causing secondary injuries when users forcefully break through the limits. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable martial arts movement correction device to solve the problems in the existing martial arts movement correction devices, such as poor real - time performance and high cost due to dependence on manual / electronic devices, and the easy occurrence of sports injuries caused by rigid limiting.

[0009] Further, the transmission mechanism includes a moving rod coaxially arranged with the winding member. The top end of the moving rod is connected to the first limiting member, and a driving component capable of driving the moving rod to move downward along the axial direction of the winding member is connected to the outside of the moving rod.

[0010] Further, the driving component includes a slide rail spirally arranged on the outer side wall of the moving rod.

An internal gear ring is meshed with one side of the second gear, and the outer side wall of the internal gear ring is fixedly connected to the turntable.

[0012] Further, the second limiting member includes an A annular disc coaxially arranged with the winding member. The lower surface of the A annular disc is fixedly connected to the winding member. A plurality of grooves are arranged on the A annular disc in a circumferential array centered on the axis of the A annular disc. The first limiting member includes a housing. The inner side wall of the housing is slidably connected to the fixed housing. A B annular disc is slidably mounted inside the housing. A plurality of protrusions matching the grooves are arranged on the B annular disc. An elastic member is arranged between the B annular disc and the housing. An adjusting component for driving the housing to move relative to the moving rod along the height direction of the moving rod is connected to one side of the housing.

[0013] Further, the adjusting component includes a screw rod. An A hole is opened at the top end of the moving rod.

The transmission mechanism drives the contact between the first limit member and the second limit member to achieve hierarchical adjustment of the self-rotation resistance of the winding member. When the elbow joint approaches the set threshold, the frictional resistance increases, providing both clear tactile feedback and avoiding the impact caused by rigid braking, forming a soft constraint protection mechanism;

[0019] When the protrusions and grooves of the limit assembly come into contact, vibrations and sounds are generated to form multi-sensory warning signals. Users can simultaneously perceive the resistance change and auditory reminder, improving the response speed of movement correction;

[0020] Through the provided adjustment assembly, the distance between the A annular disc and the B annular disc can be effectively adjusted, allowing users to preset the extension angle threshold of the elbow joint under different martial arts movements to meet the requirements of various training scenarios.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Please refer to Figures 1 to 3 , A portable martial arts movement correction device, including a first restraint member 100 and a second restraint member 200, the first restraint member 100 and the second restraint member 200 are respectively fixed to the arm and forearm of the user, and further includes: a pulling rope 300, a fixed shell 400, a winding member 500, a limiting assembly 600, and a transmission mechanism 700;

[0036] The fixed shell 400 is installed on the first restraint member 100, the winding member 500 is rotatably installed inside the fixed shell 400, a torsion spring 410 is provided between the winding member 500 and the fixed shell 400, and both ends of the torsion spring 410 are fixedly connected to the winding member 500 and the fixed shell 400 respectively;

[0037] One end of the pulling rope 300 is connected to the second restraint member 200, and the other end of the pulling rope 300 extends into the fixed shell 400 and is wound around the winding member 500;

[0038] The limiting component 600 includes a first limiting member 610 and a second limiting member 620. One side of the first limiting member 610 is fixedly connected to the winding member 500, and one side of the second limiting member 620 is connected to the transmission mechanism 700. The transmission mechanism 700 can drive the first limiting member 610 to move towards the second limiting member 620 until they are in contact, and increase the frictional resistance of the winding member 500 to rotate self.

[0039] When the user practices the arm martial arts movement to extend the elbow joint, the pull rope 300 is pulled out along with the second restraint member 200 fixed to the user's forearm. The torsion spring 410 is twisted and maintains the tension of the pull rope 300. When the elbow joint extension is about to exceed the set angle, the transmission mechanism 700 drives the first limiting member 610 to move towards the second limiting member 620. The first limiting member 610 comes into contact with the second limiting member 620. At this time, under the action of the first limiting member 610, the resistance of the winding member 500 to rotate self increases to hinder the unwinding of the pull rope 300, so as to realize the bending angle when the user extends the elbow joint during the arm martial arts movement. The user perceives the hindrance to continue extending the elbow joint, so as to realize the physical restraint mechanism when the user practices the arm martial arts movement. And the set pull rope 300, the first restraint member 100 and the second restraint member 200 do not interfere with the user's other actions, and are only used to limit the bending angle when the user extends the elbow joint, so as to realize the correction when the user practices the martial arts movement.

[0040] Please refer to Figure 3 , in an embodiment of the present invention, the transmission mechanism 700 includes a moving rod 710 coaxially arranged with the winding member 500. The top end of the moving rod 710 is connected to the first limiting member 610, and a driving component capable of driving the moving rod 710 to move downward along the axial direction of the winding member 500 is connected to the outside of the moving rod 710;

[0041] Specifically, when the user practices the arm martial arts movement to extend the elbow joint, the pull rope 300 is pulled out. At this time, the winding member 500 rotates self to unwind the pull rope 300. At the same time, the driving component synchronously drives the moving rod 710 to move downward along the axial direction of the winding member 500. The moving rod 710 drives the first limiting member 610 to move downward. When the elbow joint extension is about to exceed the set angle, the first limiting member 610 moves to contact the second limiting member 620.

[0042] Please refer to Figures 3 to 7, in an embodiment of the present invention, the driving component includes a spiral-shaped slide rail 720 provided on the outer side wall of the moving rod 710. Installation frames 730 are provided on both sides of the moving rod 710. Two rollers 740 are rotatably installed on the installation frames 730. A part of the slide rail 720 is located between the two rollers 740. A same turntable 750 is fixedly connected to one side of the two installation frames 730. The bottom end of the turntable 750 is rotatably connected to the inner wall of the fixed shell 400. A driving component 760 capable of driving the turntable 750 to rotate around its own axis is connected to one side of the turntable 750;

[0043] Specifically, when the winding member 500 rotates self to unwind the pulling rope 300, the driving component 760 drives the turntable 750 to rotate synchronously. The turntable 750 drives the two rollers 740 to rotate synchronously through the installation frames 730. The rollers 740 push against the slide rail 720, and the slide rail 720 drives the moving rod 710 to move downward, and the moving rod 710 drives the first limiting member 610 to move downward.

[0044] Please refer to Figure 3 、 Figure 5 and Figure 6 , in an embodiment of the present invention, the driving component 760 includes an annular plate 761. The outer side wall of the annular plate 761 is rotatably connected to the fixed shell 400. A transmission shaft 762 is rotatably installed on the annular plate 761. A first gear 763 and a second gear 764 are fixedly sleeved on the outside of the transmission shaft 762. An external gear ring 765 is meshed with one side of the first gear 763. The external gear ring 765 is fixedly sleeved on the bottom outside of the winding member 500. An internal gear ring 766 is meshed with one side of the second gear 764. The outer side wall of the internal gear ring 766 is fixedly connected to the turntable 750;

[0045] Specifically, when the winding member 500 rotates self to unwind the pulling rope 300, the winding member 500 drives the external gear ring 765 to rotate. The external gear ring 765 drives the first gear 763 to rotate, and further drives the transmission shaft 762 and the second gear 764 to rotate synchronously. The second gear 764 drives the turntable 750 to rotate through the internal gear ring 766. Through the transmission of the first gear 763, the second gear 764, the external gear ring 765 and the internal gear ring 766, the rotation speed of the turntable 750 is reduced, and the rotational motion of the turntable 750 is converted into the axial movement of the moving rod 710 through the cooperation of the provided slide rail 720 and the rollers 740, so as to realize the movement of the first limiting member 610.

[0046] Please refer to Figure 3 、 Figure 8 and Figure 9, in an embodiment of the present invention, the second limiting member 620 includes an A-shaped annular disk 621 coaxially arranged with the winding member 500. The lower surface of the A-shaped annular disk 621 is fixedly connected to the winding member 500. A plurality of grooves 622 are formed on the A-shaped annular disk 621 in a circumferential array centered on the axis of the A-shaped annular disk 621. The first limiting member 610 includes a housing 614. The inner side wall of the housing 614 is slidably connected to the fixed housing 400. A B-shaped annular disk 611 is slidably installed inside the housing 614. A plurality of protrusions 613 cooperating with the grooves 622 are formed on the B-shaped annular disk 611. An elastic member 615 is arranged between the B-shaped annular disk 611 and the housing 614. The elastic member 615 is a B-shaped spring. One side of the housing 614 is connected with an adjusting assembly for driving the housing 614 to move relative to the moving rod 710 along the height direction of the moving rod 710;

[0047] Specifically, when the moving rod 710 moves downward, the moving rod 710 drives the housing 614 to move downward through the adjusting assembly. The housing 614 drives the B-shaped annular disk 611 to move downward through the elastic member 615. After the protrusions 613 on the B-shaped annular disk 611 contact the A-shaped annular disk 621, the elastic member 615 is compressed. At this time, the winding member 500 is still unwinding the pulling rope 300. Thus, the winding member 500 drives the A-shaped annular disk 621 to rotate. Under the action of the elastic member 615, the protrusions 613 on the B-shaped annular disk 611 continuously move into / out of the grooves 622 on the A-shaped annular disk 621, and the A-shaped annular disk 621 continuously contacts / separates from the B-shaped annular disk 611 to emit sounds and vibrations to remind the user. At this time, the user can perceive the reminder according to the emitted sounds. And if the user continues to extend the elbow joint, the friction force continuously increases, and the user can obviously perceive the obstruction until the winding member 500 cannot rotate, so as to avoid the situation that when the user corrects the elbow joint extension movement, a hard way of directly limiting the elbow joint extension angle is adopted for correction, resulting in the user being injured or the device being easily damaged;

[0048] And the housing 614 is driven to move relative to the moving rod 710 along the height direction of the moving rod 710 through the adjusting assembly, that is, the initial distance between the A-shaped annular disk 621 and the B-shaped annular disk 611 is adjusted, that is, the length that the pulling rope 300 can be unwound is adjusted to adapt to the limitation of the elbow joint extension angle under different martial arts movements, thereby improving the applicability of the device.

[0049] Please refer to Figure 3 and Figure 9 , in an embodiment of the present invention, the adjusting assembly includes a screw rod 616. An A-shaped hole 711 is formed at the top end of the moving rod 710. The bottom end of the screw rod 616 is rotatably connected to the bottom surface of the A-shaped hole 711. A sleeve 612 is sleeved outside the screw rod 616. The top end of the sleeve 612 is fixedly connected to the housing 614. The outer side wall of the bottom end of the sleeve 612 is slidably connected to the inner wall of the A-shaped hole 711. The inner side wall of the bottom end of the sleeve 612 is threadedly connected to the screw rod 616;

[0050] Specifically, during adjustment, by rotating the screw rod 616, since the outer shell 614 is slidably connected to the fixed shell 400 and the sleeve 612 is slidably connected to the moving rod 710, when the screw rod 616 rotates, it will drive the outer shell 614 to move through the sleeve 612, thereby realizing the movement of the outer shell 614 relative to the moving rod 710 along the height direction of the moving rod 710.

[0051] Please refer to Figure 3 , in an embodiment of the present invention, an A spring 770 is provided at the bottom end of the moving rod 710, and both ends of the A spring 770 are fixedly connected to the moving rod 710 and the fixed shell 400 respectively, and the A spring 770 is used to assist the moving rod 710 to reset.

[0052] Please refer to Figure 1 , in an embodiment of the present invention, the first restraint member 100 includes an A guard plate 110, and A straps 120 are fixedly connected to both ends of the A guard plate 110. The fixed shell 400 is fixedly installed on the A guard plate 110. The second restraint member 200 includes a B guard plate 210, and B straps 220 are fixedly connected to both ends of the B guard plate 210. One end of the pull rope 300 away from the fixed shell 400 is fixedly connected to the B guard plate 210;

[0053] Specifically, the A guard plate 110 and the B guard plate 210 are fixed to the user's arm and forearm respectively through the A straps 120 and the B straps 220, which is convenient for the user to wear. The A straps 120 and the B straps 220 can be used in combination with existing webbing and Velcro.

[0054] Please refer to Figure 1 , in an embodiment of the present invention, one end of the A guard plate 110 is hinged to one end of the B guard plate 210. During use, the hinge joint between one end of the A guard plate 110 and the B guard plate 210 is set at the user's elbow joint, making the wearing and use of the device more stable. And when not in use, one end of the A guard plate 110 and the B guard plate 210 can be rotated around the hinge joint to reduce the storage volume and facilitate carrying.

[0055] Please refer to Figure 4 and Figure 9 , in an embodiment of the present invention, a B hole 420 for the pull rope 300 to pass through is provided on the fixed shell 400, and a plurality of balls 430 are embedded on the inner wall of the B hole 420 to reduce the wear of the pull rope 300 and extend the service life of the device.

[0056] Only certain exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
