Description

Technical Field

[0001] The invention belongs to the technical field of sports training and relates to a Tai Chi teaching and training system. Background Art

[0003] The footwork of Tai Chi is very important. The foundation of Tai Chi lies in the feet. The correctness of the footwork directly affects the overall effect and quality of Tai Chi practice. The footwork of Tai Chi is similar to the way humans walk. Both use the method of "first subtract and then add" to complete the change of the center of gravity of the left and right feet. The change of the virtuality and reality of the feet is also gradual, not sudden. This change process requires delicate mastery. Tai Chi footwork training includes the close coordination of the soles, heels, and the soles of the feet, which is the basis for the coherence of Tai Chi movements and the transmission of power. Relaxation of the feet is also the key. The toes, soles, and heels all need to be relaxed, so as to achieve smooth transmission of power and stable control of the body. In addition, the virtuality and reality of the feet also need to be mastered. When the real foot becomes the virtual foot, it is necessary to first subtract and then add, and it cannot change suddenly. In general, in the process of practicing Tai Chi, the training of the feet is regarded as the basic guarantee for improving the quality of Tai Chi. Although many practitioners are proficient in routines, it is difficult for them to achieve high-level boxing skills because they do not work hard on their footwork. Therefore, correct practice of footwork is crucial to the overall practice of Tai Chi. The prior art lacks a corresponding training system. For this reason, a public technology on the market proposes a Tai Chi training device, which includes a mounting plate and a plurality of pedals. The pedal includes a pedal body and a mounting portion integrally formed with the pedal body. The mounting plate is provided with a plurality of circular mounting grooves, and the mounting portion can be inserted into the mounting groove to fix the pedal on the mounting plate. A first mounting cavity and a second mounting cavity are respectively provided inside the two ends of the pedal body, and the first mounting cavity and the second mounting cavity are respectively provided with a first mounting cavity and a second mounting cavity. A first pressure sensor and a second pressure sensor are provided, and the first pressure sensor and the second pressure sensor control the first indicator light and the second indicator light respectively; the Tai Chi training device is convenient for standardizing the trainer's stride, footfall position and footfall method, which is conducive to the rapid entry and further improvement of Tai Chi trainers. In the actual application of the disclosed technology, there are certain disadvantages. First, the pressure sensor provided is only used to detect whether the foot has landed, give a signal to the control part, and then control the indicator light of the next footfall point to light up, that is, the pressure sensor is only used to control the indicator light, and does not involve the virtuality and reality of the footsteps and the conversion of the center of gravity of the foot. Moreover, the pedal body provided needs to be pre-installed, which is very troublesome to use. The overall rigid setting is not easy to carry;

[0004] There is also a public technology on the market that proposes a multifunctional Tai Chi training device, including a training mechanism, a display mechanism is arranged on one side of the training mechanism, the training mechanism includes a training base and a circular clamp ring, the training base includes a training frame, a rubber support pad, a first rubber plate and a second rubber plate, a fixed connection groove is arranged on one side of the training frame, and a circular clamping groove is opened at the upper edge of the training frame; the public technology states that by the user standing on the upper side of the second rubber plate and the first rubber plate, the second rubber plate and the first rubber plate are pressed down and embedded in the first sensing card slot and the second sensing card slot respectively, so that the pressure sensor arranged on the inner side of the first sensing card slot and the second sensing card slot senses the pressure, and then transmits it to the display screen through the power connection line to display the stepping point position, so that the user can adjust his position according to the information on the display screen. In the public technology, the user can only determine the landing point of each step according to the teaching video, and then confirm whether the landing point is correct through the sensor, which is very inconvenient for training. The sensor in the technology also does not detect the virtuality and reality of the footsteps and the center of gravity conversion of the foot. Moreover, it also has the problem of inconvenience in carrying like the aforementioned public technology;

DETAILED DESCRIPTION

[0036] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0037] like Figures 1 to 6 As shown, this embodiment proposes a Tai Chi teaching and training system, including a controller, a display, a storage tube 1 and a teaching mat. The controller and the display are both mature technologies on the market. The controller can be any one of a desktop computer, a laptop computer or a microcomputer controller, which is used to record Tai Chi teaching and training videos and control programs. The display can be any one of a television, a computer display, an outdoor large screen or a projection device, which is used to display teaching videos and feedback information during use;

[0038] In order to achieve the function of portability, the teaching mat is rolled up and stored inside the storage tube 1. One axial end of the storage tube 1 is connected to the tube cover 2 through a zipper 3. The inner wall of the storage tube 1 is provided with a buffer structure for protecting the teaching mat. The buffer structure includes a buffer layer 4 and a plurality of air storage cavities 401. The buffer layer 4 is provided on the inner wall of the storage tube 1. The plurality of air storage cavities 401 are evenly distributed on the inner wall of the buffer layer 4. The teaching mat can be stored in the storage tube 1 after being rolled up, and can be carried more conveniently. After the upper end of the storage tube 1 is connected to the tube cover 2 through the zipper 3, the teaching mat can be prevented from slipping out of the upper opening of the storage tube 1 during carrying. The buffer layer 4 with a plurality of air storage cavities 401 on the inner wall of the storage tube 1 can play a better buffering and protective role when the teaching mat is stored, effectively improving the service life of the teaching mat.

[0039] In order to facilitate winding, the teaching pad is composed of a winding core 5, a soft pad wound on the outer wall of the winding core 5, and a wire 7 arranged at one end of the soft pad away from the winding core 5. The radius of the winding core 5 is greater than the minimum bending radius of the soft pad. The unfolded shape of the soft pad is either rectangular or square. By setting the winding core 5, the soft pad can be conveniently wound along the outer wall of the winding core 5. After constraining the radius of the winding core 5, it can be avoided that the winding radius is less than the minimum bending radius of the soft pad, thereby effectively avoiding the internal circuit breakage and damage caused by too small winding bending radius;

[0040] In order to achieve internal waterproofing, the soft cushion includes a cushion body and a frame 6 wrapped around the cushion body. One side of the frame 6 is fixedly connected to the outer wall of the roll core 5. A waterproof structure is arranged between the frame 6 and the cushion body. The waterproof structure includes two waterproof glues 9. The cross section of the frame 6 is U-shaped with the mouth facing the cushion body. The edge of the cushion body is connected to the inside of the U-shaped opening of the frame 6. The two waterproof glues 9 are respectively arranged between the upper wall of the cushion body and the frame 6 and between the lower wall of the cushion body and the frame 6. The waterproof glue 9 is any one of a polyurethane waterproof material, a rubber waterproof material and an acrylic waterproof material. The waterproof glue 9 can well prevent water from entering the interior from the connection between the frame 6 and the cushion body, avoid internal short circuit, achieve a better waterproof effect, and improve the safety of use.

[0041] In order to realize the teaching and training function, the mat body is composed of a surface layer 8 for stepping on, a light-emitting layer 11 for indicating the stepping position, a substrate layer 12 for carrying the light-emitting layer 11, a pressure detection layer 14 for detecting the range of the footfall and the footfall pressure, and a bottom layer 16 for the bottom cover, which are arranged in sequence from the inside to the outside in a winding state;

[0042] The surface layer 8 is composed of a rubber pad 801 and a frosted layer 802. The frosted layer 802 is arranged on the side of the rubber pad 801 away from the luminous layer 11. The rubber pad 801 is highly transparent silicone. The thickness of the rubber pad 801 is 4 mm. By arranging the frosted layer 802 on the rubber pad 801, a better anti-slip effect can be provided to prevent the user from slipping when training on the surface layer 8. The indicator light emitted by the luminous layer 11 can penetrate the highly transparent silicone. The user can stand on the surface layer 8 and can see the indicator light more easily, so as to train according to the correct footwork sequence.

[0043] In order to indicate the correct order of footwork, the light-emitting layer 11 is composed of multiple groups of LED patches, which are arranged in a rectangular shape on the side of the substrate layer 12 facing the surface layer 8. The LED patches are any one of 0201 patches, 0402 patches and 0603 patches. The substrate layer 12 is an FPC flexible circuit board. The multiple groups of LED patches can be lit up separately according to the set program through the controller. The lit area can form a shape similar to the sole of the foot, so that the user can confirm the landing position of each step. The order of stepping on the lit areas can be distinguished by the different colors emitted by the LED patches, and can also be distinguished by displaying Arabic numerals of the corresponding order on the side of the formed footprint shape.

[0044] In order to confirm whether the footfall position and footfall force are correct, the pressure detection layer 14 is a thin film pressure sensor. Through the thin film pressure sensor, when used for the first time, after the user stands on the teaching mat, the thin film pressure sensor can detect the size of the user's sole through the stepped range. By using the thin film pressure sensor to detect the weight of the user, the controller can infer the height of the user according to the size of the sole, so as to adjust the distance between the footfall points of each step according to different stride amplitudes at different heights. By obtaining the weight, the footfall force in subsequent use can be conveniently calculated, and the footfall force can be measured more accurately, especially whether the conversion of the center of gravity after the footfall is correct can be recorded. During training, whether the footfall point is accurate, whether the footfall force is accurate, and whether the center of gravity conversion is correct can all be displayed on the display. The user can correct the incorrect part and train again until it is fully mastered;

[0045] In order to support the user and prevent slipping after laying, an anti-skid structure is provided on the side of the bottom layer 16 away from the pressure detection layer 14 for preventing slipping when the mat body contacts the ground after unfolding. The anti-skid structure is an anti-skid layer 17. The anti-skid layer 17 is glued to the side of the bottom layer 16 away from the pressure detection layer 14. The side of the anti-skid layer 17 away from the bottom layer 16 is a plane. The anti-skid layer 17 is anti-skid rubber. The thickness of the anti-skid layer 17 is 5 mm. The bottom layer 16 plays a major supporting role. When laying, the contact between the anti-skid layer 17 and the ground can avoid displacement during use, thereby further improving the safety of use.

[0046] In order to ensure a good insulation effect, an insulating structure is arranged between the light-emitting layer 11 and the surface layer 8, between the substrate layer 12 and the pressure detecting layer 14, and between the pressure detecting layer 14 and the bottom layer 16. The insulating structure includes a first insulating layer 10, a second insulating layer 13 and a third insulating layer 15. The first insulating layer 10 is arranged between the light-emitting layer 11 and the surface layer 8, the second insulating layer 13 is arranged between the substrate layer 12 and the pressure detecting layer 14, and the third insulating layer 15 is arranged between the pressure detecting layer 14 and the bottom layer 16. The first insulating layer 10, the second insulating layer 13 and the third insulating layer 15 are all made of any one of polyimide, polyethylene, polyvinylidene fluoride and polytetrafluoroethylene. The thickness of the first insulating layer 10, the second insulating layer 13 and the third insulating layer 15 is 0.2 mm. Through the three groups of insulating layers, the insulation of the upper and lower sides is met, and the good insulation between the pressure detecting layer 14 and the light-emitting layer 11 is also guaranteed.

[0047] Working principle: In this embodiment, the controller and the display are both mature technologies in the market. The controller can be any one of a desktop computer, a laptop computer or a microcomputer controller, which is used to record Tai Chi teaching and training videos and control programs. The display can be any one of a television, a computer monitor, an outdoor large screen or a projection device, which is used to display teaching videos and feedback information during use; the teaching mat can be stored in the storage tube 1 after being rolled up, and can be carried more conveniently. After the upper end of the storage tube 1 is connected to the tube cover 2 through a zipper 3, the teaching mat can be prevented from slipping out of the upper opening of the storage tube 1 during carrying. The buffer layer 4 with multiple air storage cavities 401 on the inner wall of the storage tube 1 can play a good buffering and protection role when the teaching mat is stored, effectively improving the teaching experience. The service life of the school pad, the radius of the winding core 5 is greater than the minimum bending radius of the soft pad, and the unfolded shape of the soft pad is either rectangular or square. By setting the winding core 5, the soft pad can be conveniently wound along the outer wall of the winding core 5. After constraining the radius of the winding core 5, it can be avoided that the winding radius is less than the minimum bending radius of the soft pad, thereby effectively avoiding the internal circuit breakage and damage caused by the winding bending radius being too small; the waterproof glue 9 is any one of polyurethane waterproof material, rubber waterproof material and acrylic waterproof material. The waterproof glue 9 can well prevent water from entering the interior from the connection between the frame 6 and the pad body, avoid internal short circuit, play a good waterproof effect, and improve the safety of use. By setting a frosted layer 802 on the rubber pad 801, a good anti-slip effect can be provided. To prevent the user from slipping when training on the surface layer 8, the indicator light emitted by the light-emitting layer 11 can penetrate the highly transparent silicone, and the user can easily see the indicator light when standing on the surface layer 8, so as to train according to the correct footwork sequence; the LED patch is any one of the 0201 patch, the 0402 patch and the 0603 patch, and the substrate layer 12 is an FPC flexible circuit board. Multiple groups of LED patches can be lit up separately according to the set program through the controller, and the illuminated area can form a shape similar to the sole of the foot, so that the user can confirm the landing position of each step. The order of stepping on the illuminated areas can be distinguished by the different colors emitted by the LED patches, and can also be distinguished by displaying Arabic numerals of the corresponding order on the side of the formed footprint shape. When used for the first time, after the user stands on the teaching mat, the thin film pressure sensor can detect the size of the user's sole through the stepped range. By using the thin film pressure sensor to detect the user's weight, the controller can infer the user's height according to the size of the sole, so as to adjust the distance between the footfalls of each step according to the different stride amplitudes at different heights. By obtaining the weight, the footfall force in subsequent use can be conveniently calculated, and the footfall force can be measured more accurately, especially whether the conversion of the center of gravity after the footfall is correct can be recorded. During training, whether the footfall point is accurate, whether the footfall force is accurate, and whether the center of gravity conversion is correct can all be displayed on the display. The user can correct the incorrect part and train again until it is fully mastered.The bottom layer 16 plays a major supporting role. When laid, the contact between the anti-slip layer 17 and the ground can avoid displacement during use, further improving the safety of use; the first insulating layer 10, the second insulating layer 13 and the third insulating layer 15 are all made of any one of polyimide, polyethylene, polyvinylidene fluoride and polytetrafluoroethylene. The thickness of the first insulating layer 10, the second insulating layer 13 and the third insulating layer 15 is 0.2mm. Through the three sets of insulating layers, the insulation of the upper and lower sides is met, and the good insulation between the pressure detection layer 14 and the light-emitting layer 11 is also guaranteed. ;
