Description

Technical Field

[0001] The present application relates to the technical field of electronic protective gear, and in particular to an RFID-sensitive Taekwondo electronic protective gear. Background Art

[0002] Taekwondo electronic protective gear is a type of protective gear that detects strikes and automatically keeps score, unlike traditional Taekwondo protective gear. It consists of a torso protector and electronic sensor socks. By installing an electronic sensor chip in the protective gear, when a kick lands in a specific area and reaches a certain force, the sensor area transmits a score signal, which is then transmitted to the scoreboard via radio.

[0003] An existing patent (publication number: CN217724534U) discloses an RFID-sensitive Taekwondo electronic protective gear, comprising a foot guard and a waist guard. The foot guard is provided with a flexible RFID chip. The waist guard includes an RFID read / write antenna corresponding to the flexible RFID chip, a spacer layer, and a flexible pressure sensor. The RFID read / write antenna, spacer layer, and flexible pressure sensor are stacked and connected in sequence along the waist guard from the outside to the inside. The beneficial effect of the utility model is that when the foot guard hits the waist guard, the flexible RFID chip in the foot guard and the RFID read / write antenna in the waist guard come into contact. The RFID read / write antenna and the flexible RFID chip generate an electrical signal, and the RFID read / write antenna squeezes the flexible pressure sensor, which then brings the two plates of the first and second flexible conductive layers closer together, causing their capacitance value to increase. The controller can not only receive the electrical signal from the RFID read / write antenna, but also measure the impact force by detecting the change in the capacitance value, thereby improving the accuracy of the impact scoring.

[0004] When Taekwondo athletes compete, different scores will be obtained for different striking movements. The above-mentioned electronic protective gear cannot capture the athlete's movement trajectory when used, and thus cannot determine the score based on the athlete's specific movements. It is easy to make misjudgments, affecting the accuracy of the score. It has certain defects, and it is not convenient to maintain and replace the RFID read / write antenna and flexible RFID chip when they are damaged. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides an RFID-sensing Taekwondo electronic protective gear, which has the advantages of being able to capture the athlete's motion trajectory and then determine the athlete's score based on the athlete's specific movements, thereby improving the accuracy of the score. It also facilitates the replacement and maintenance of the RFID read-write antenna and the flexible RFID chip when they are damaged. This solves the problem that the existing electronic protective gear cannot capture the athlete's motion trajectory when in use, and cannot determine the athlete's score based on the athlete's specific movements, which is prone to misjudgment and affects the accuracy of the score. It has certain defects, and is inconvenient to maintain and replace the RFID read-write antenna and the flexible RFID chip when they are damaged.

[0006] To achieve the above objectives, the present application provides the following technical solutions: an RFID-sensing Taekwondo electronic protective gear, comprising a mounting sleeve, an IMU sensor is arranged inside the mounting sleeve, and a 9-axis acceleration sensor is arranged inside the mounting sleeve.

In addition, when the RFID read-write antenna and the flexible RFID chip are damaged, it is inconvenient to maintain and replace them. By providing a mounting sleeve and arranging an IMU sensor and a 9-axis acceleration sensor inside the mounting sleeve, the athlete's movements during the game can be captured in real time, and then the score can be judged based on the athlete's specific movements, thereby improving the accuracy of the score. By opening a mounting groove inside the waist protective base layer and installing and fixing the RFID read-write antenna by bonding, the RFID read-write antenna is facilitated for disassembly and maintenance. By providing a placement layer on the outside of the foot protective base layer and installing and storing the flexible RFID chip by bonding, the flexible RFID chip is facilitated for disassembly and maintenance.

[0010] Furthermore, the installation sleeve is made of spandex blended fabric.

[0011] Through the above solution, the blended spandex fabric is light in weight and high in strength, and also has good air permeability and ductility, which can improve the comfort of athletes when wearing it.

[0012] Furthermore, one end of the mounting sleeve is fixedly connected to a hanging rope, and the other end of the mounting sleeve passes through the inside of the hanging rope and is folded back.

[0014] Furthermore, the outer surface of the installation sleeve is fixedly connected to a first rough surface, the outer surface of the installation sleeve is fixedly connected to a first hook surface, and the first rough surface and the first hook surface are bonded.

[0015] Through the above scheme, the folded mounting sleeve is bonded and fixed by the first furry surface and the first hook surface, which makes it easy to install the mounting sleeve on different parts of the body such as the wrist and ankle, and then the athlete's attacking action is captured under the action of the IMU sensor and the 9-axis acceleration sensor, thereby improving the accuracy of scoring.

[0016] Furthermore, the upper surface of the soft backboard is fixedly connected with a third fleece surface, the upper surface of the waist protection base layer is fixedly connected with a third hook surface, and the third fleece surface is bonded to the third hook surface.

[0017] Through the above solution, the soft backboard and the RFID read-write antenna can be reinforced by the third fleece surface and the third hook surface, thereby improving the stability of the RFID read-write antenna.

[0018] Furthermore, an antenna is fixedly connected to the top of the RFID read / write antenna, and a notch adapted to the antenna is provided inside the waist protection base layer.

[0019] Through the above solution, the gap can accommodate the antenna, making it easy to place the antenna.

[0020] Furthermore, the upper surface of the waist protection base layer is fixedly connected with a fourth hairy surface, the upper surface of the waist protection base layer is fixedly connected with a fourth hook surface, the fourth hairy surface and the fourth hook surface are located above the notch, and the fourth hairy surface and the fourth hook surface are bonded.

[0021] Through the above solution, the fourth rough surface and the fourth hook surface can be used to block the gap, thereby preventing the antenna inside the gap from sliding out and causing damage to itself, thereby affecting signal transmission.

[0022] Furthermore, it also includes a head guard, wherein the interior of the head guard is provided with a mounting groove adapted to the shape thereof, an RFID read / write antenna, a second fleece surface, a soft back plate and a second hook surface.

[0023] Through the above solution, the RFID read-write antenna inside the head guard can also be easily disassembled when damaged, which facilitates the maintenance of the RFID read-write antenna inside the head guard.

[0024] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0025] The RFID-sensing Taekwondo electronic protective gear is provided with a mounting sleeve, and an IMU sensor and a 9-axis acceleration sensor are arranged inside the mounting sleeve, so that the athlete's movements during the competition can be captured in real time, and the score can be determined based on the athlete's specific movements, thereby improving the accuracy of the score. The RFID reader / writer antenna is conveniently maintained by providing a mounting slot inside the waist protective base layer and fixing it by bonding. The flexible RFID chip is conveniently maintained by providing a placement layer on the outside of the foot protective base layer and storing it by bonding. This solves the problem that existing electronic protective gear cannot determine the score based on the athlete's attacking movements, which affects the accuracy of the score, and the RFID chip and RFID reader / writer antenna are not convenient to disassemble and maintain.
