Description

Technical Field

[0001] This utility model relates to the field of sports equipment, specifically to a novel connecting cable for fencing, fencing protective equipment, and a fencing scoring system. Background Technology

[0002] In the field of fencing, the official competition events certified by the International Fencing Federation (FIE) include épée. The competition is divided into three disciplines: Sabre, Foil, and Spaghetti. According to FIE competition rules, athletes must wear certified conductive metal protective gear (including a metal vest and metal face shield). This gear provides safety and also serves as a sensor for the electronic judging system to identify valid strikes. Current mainstream competition systems use wired electronic judging devices. The technical principle is to create a closed circuit by connecting the athlete's sword's conductive parts, the conductive metal protective gear, and the central judging device via physical wires. When a valid strike occurs, the sword tip / edge forms a current path with the conductive metal protective gear, triggering the scoring signal on the judging device.

[0003] However, this wired refereeing system has the following technical flaws: Because the hand-clip connector (alligator clip) is mechanically connected to the metal vest, during high-intensity competition, the athlete's movements can easily cause connector displacement or oxidation of the contact surface, resulting in increased contact resistance or even complete detachment. In this situation, the closed loop formed by the metal vest, sword, and refereeing device will be in an unstable conductive state. When the sword makes substantial contact with the valid striking point, the refereeing device cannot correctly identify the valid signal due to the disruption of circuit integrity.

[0004] While some existing technologies have attempted to alleviate this problem by improving the alligator clip structure or adding auxiliary fixing devices, none have fundamentally solved the inherent defects of mechanical contact connections. Therefore, there is an urgent need for a new referee device solution that can overcome the physical limitations of wired systems. Utility Model Content

[0005] This utility model provides a novel connecting cable for fencing, fencing protective equipment, and a fencing scoring system, to at least solve the technical problem in the prior art that the effective contact between the connecting cable and the fencing protective equipment cannot be detected.

[0006] According to one aspect of the embodiments of this application, a connecting cable for fencing is provided, comprising: a connecting cable body; a clamping member disposed at the end of the connecting cable body for clamping fencing protective equipment to establish a conductive connection between the connecting cable body and the fencing protective equipment, wherein the fencing protective equipment includes a metal vest and / or a metal faceplate; and a sensor module disposed on the connecting cable body or the clamping member for detecting the electrical connection status of the conductive connection.

[0007] This embodiment, by setting up sensors, can maintain the fairness of fencing competitions, reduce misjudgments caused by the referee's blind spots, and prevent cheating caused by equipment failure, loose wire clips, or incorrect connection of the wires by the athletes.

[0008] In some embodiments, when the electrical connection is not electrically connected, the sensor module is also configured to generate an alarm signal. With this structure, an alarm can be automatically triggered when an abnormal connection is detected, alerting the referee to the connection problem.

[0009] In some embodiments, when the connecting line is used as a hand line, one end of the connecting line body is a sword hilt interface for connecting to the fencing weapon, and the other end has a first branch and a second branch. The first branch has a clamp at its end for electrical connection with the metal vest, and the second branch has a main cable interface for connecting to a main cable 19, which then electrically connects to a cable reel. With this structure, the fencing weapon, metal vest, and scorer are connected in a loop using the hand line.

[0010] In some embodiments, when the connecting wire is used as a head wire, clamping members are respectively provided at both ends of the connecting wire body. One clamping member is used to form an electrical connection with the metal jacket, and the other clamping member is used to form an electrical connection with the metal faceplate. With the above structure, the metal faceplate and metal jacket are electrically connected using the head wire to form a circuit with the score counter.

[0011] In some embodiments, the sensor module is disposed at any of the following locations: on the outer surface of the connecting cable body; inside the conductor core of the connecting cable body; or at the conductive contact portion of the clamping member. By disposing the sensor module at the above locations, the connection status can be detected more accurately.

[0012] In some embodiments, the sensor module is used to detect the current flow rate of the conductive connection in real time, and when the current flow rate is less than a preset threshold, the electrical connection status is determined to be non-electrical connection; otherwise, the electrical connection status is determined to be electrical connection. This embodiment improves detection accuracy, avoids misjudgment, and ensures the reliability of the fencing scoring system by accurately determining the electrical connection status through real-time current flow rate detection.

[0013] In some embodiments, the alarm signal is presented in at least one of the following ways: optical indication by a light-emitting diode integrated on the sensor module; an acoustic alarm module integrated on the sensor module; or a vibration feedback signal wirelessly transmitted to the referee's terminal. Through these solutions, fencing referees can promptly detect the electrical connection status, thereby avoiding misjudgments.

[0014] When the connecting line is used as a hand line, the sensor module is disposed on the first branch or on the clamp located at the end of the first branch. By disposing the sensor module on the first branch or the clamp of the first branch, the electrical connection status can be sensed more accurately.

[0015] This application embodiment also provides fencing protective equipment, including: a metal vest configured to cover the target area of ​​the fencer's body and connected to the fencing weapon via a hand line; and / or a metal face shield configured to cover the target area of ​​the fencer's head and connected to the metal vest via a head line; wherein the hand line and / or the head line are connecting lines as described above.

[0016] This application also provides a fencing scoring system, including: fencing protective equipment as described above; a referee device, the referee device being configured to form a closed loop with the fencing protective equipment, and being configured to update the score based on the conduction state of the closed loop when the fencing weapon contacts the opponent's fencing protective equipment.

[0017] This application embodiment solves the technical problem in the prior art that the effective contact between the connecting line and the fencing protective equipment cannot be detected by setting a sensor on the connecting line. Attached Figure Description

[0033] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0034] This application provides a fencing scoring system, such as... Figure 2 As shown, the system includes fencing protective gear for both athletes, hand lines 14, head lines 16, fencing weapons 17, string reels 18, and referee equipment 20. The fencing protective gear includes a metal vest 10 and a metal face shield 12.

[0035] The metal suit 10, used to cover the athlete's torso, may be made of conductive fibers and is connected to the referee's apparatus 20 via hand lines 14, main lines 19, and a reel 18. The metal face shield 12, used to protect the athlete's head, also has a conductive mesh metal portion and is connected to the metal suit 10 via a head line 16.

[0036] The cable reel 18 is installed on the competition field. One end is connected to the hand line 14 via a retractable cable 19, and the other end is connected to the referee device 20 via a retractable cable. This is used to ensure that the players can move freely while maintaining the smooth flow of the circuit and ensuring the stability of signal transmission during the competition.

[0037] The referee device 20 is the core component of the entire scoring system, responsible for receiving and analyzing hit signals and updating the match score in real time. The referee device 20 includes: a signal acquisition module for detecting the continuity of closed loops; a processing module for judging valid hits based on the match rules and calculating the score; and a display module for displaying the scores of both players and providing light or sound prompts.

[0038] refer to Figures 2 to 7The following will describe in detail what can be used as a connecting wire between hand line 14 and head line 16.

[0039] One end of the hand line 14 is a hilt interface 142 for connecting to the fencing weapon 17. The other end has a first branch and a second branch. The end of the first branch is provided with the hand line clamp 146 for forming an electrical connection with the metal vest 10. The end of the second branch is provided with a main line interface 144 for connecting to the main line 19, so as to electrically connect to the cable reel 18 through the main line 19. With the above structure, the fencing weapon 17 can form an electrical circuit with the referee's instrument 20.

[0040] A hand-cable sensor module 148 is installed on the hand-cable 14 to detect the connection status between the hand-cable 14 and the metal garment 10 in real time. The hand-cable sensor module 148 is as follows: Figure 3 and Figure 5 As shown, it can be set on the first branch, or as... Figure 4 and Figure 6 As shown, integrated within the cable clamp 146, it is used to detect the electrical connection status of the cable clamp 146, wherein the electrical connection status includes electrical connection and non-electrical connection.

[0041] One end of the head wire 16 is fixed to the metal cover 10 via a head wire clamp 164-1, and the other end is connected to the metal faceplate 12 via another head wire clamp 164-2. Figure 7 As shown. This connection method ensures that when the fencing weapon 17 contacts the metal faceplate 12, the circuit can close normally and transmit a signal to the referee device 20 to determine whether a valid hit has occurred.

[0042] A headline sensor module 162 is also provided on the headline 16 for detecting the connection status between the metal faceplate 12 and the metal cover 10. In some embodiments, such as Figure 7 As shown in (A), the head cable sensor module 162 includes a first sensor 162-1 and a second sensor 162-2, which are respectively integrated into the head cable clamps 164-1 and 164-2 at both ends of the head cable 16. In some other embodiments, such as Figure 7 As shown in (B), the head cable sensor module 162 can be positioned in the middle of the head cable 16 body. The head cable sensor module 162 can detect the electrical connection status of the head cable clamp 164 to ensure the stability of the connection.

[0043] When the sensor module detects that the clamping device is in a non-electrically connected state, it will generate an alarm signal. The alarm signal can be presented in at least one of the following ways: first, by optical indication using a light-emitting diode integrated on the metal jacket 10 or metal faceplate 12; second, by sound warning issued through the acoustic alarm module of the referee device 20; or third, by wireless transmission to the referee terminal, which will remind the referee to check the equipment connection status in the form of a vibration feedback signal.

[0044] In existing fencing scoring systems, a conduction signal is triggered only when an athlete's weapon effectively strikes a conductive area of ​​the opponent's metal vest, face shield, or glove. However, when the connection between the hand line and the weapon or vest is abnormal, although the sensor at the main wire interface can sound an alarm to indicate the fault, problems such as a detached head line or poor contact between the clamp and the vest are difficult to detect in real time. Such hidden connection failures often lead to misjudgments in scoring and even provide opportunities for athletes to cheat. Typical cheating methods include: during the trial phase, the athlete deliberately attaches the clamp to a non-conductive protective suit and presses the clamp with their hand to make it briefly contact the vest, thus forging a valid conduction signal during the trial; when the match officially begins, the athlete releases the clamp, causing the opponent to fail to score when actually striking their vest due to a broken circuit. The embodiments of this application fundamentally solve the above problems by integrating sensor modules at key connection nodes of the hand and head lines. The sensor module monitors the electrical connection status between the clamping device and the metal clothing / faceplate in real time. When abnormal current flow, insufficient clamping force, or excessive contact impedance is detected, it immediately sends an alarm message to the referee's terminal via audible and visual alarms or wireless signals. This structure not only accurately identifies hidden faults such as loose clamping devices, misalignment, or abnormal contact, but also prevents athletes from cheating by manipulating the clamping status. This ensures that the scoring system always bases its judgments on a true and valid electrical circuit, significantly improving the fairness of refereeing and the reliability of the competition results.

[0045] In some embodiments, the sensor module may employ a current sensor. This current sensor is configured to determine that the clamping element is in a non-clamping state when the current to the clamping element is below a preset threshold, thereby triggering an alarm signal. In this embodiment, the sensor operates on the opposite principle to a conventional sensor; it triggers an alarm when the current is interrupted (circuit fault or disconnection).

[0046] In some other embodiments, the sensor module can be a Hall effect sensor. This Hall effect sensor detects changes in the magnetic flux of the clamping component, and when the magnetic flux falls below a preset threshold, it determines that the clamping component is in a non-clamping state. This method is suitable for clamping components employing magnetic locking structures to ensure their stability and reliability.

[0047] In some other embodiments, the sensor module may employ a strain sensor. The strain sensor is embedded in the elastic component of the clamping member and is used to detect the deformation of the clamping member. When the deformation is below a preset threshold, the clamping member is determined to be in a non-clamping state, suitable for applications requiring precise detection of clamping loosening.

[0048] In addition, the sensor module can also employ a pressure sensor. This pressure sensor is embedded in the elastic component of the clamping member and is used to detect changes in clamping force. When the clamping degree is lower than a preset threshold, it is determined that the clamping member is in a non-clamping state, ensuring that clamping stability is not affected by external forces.

[0049] In some embodiments, the sensor module may employ a mechanical switch to directly detect the closed state of the clamping element. When the clamping element is detected to be in an incorrectly closed position, it is determined to be in a non-clamping state, thereby providing timely feedback signals so that the referee or athlete can make adjustments.

[0050] Through the above technical solution, the fencing protective equipment provided in this embodiment can effectively monitor the connection status of the equipment and provide an alarm signal when the connection is abnormal, avoiding misjudgment caused by equipment failure and improving the fairness of the competition and the accuracy of hit detection.

[0051] The circuit principle of the fencing scoring system will be described in detail below.

[0052] like Figure 8 As shown, in a fencing match, when one fencer's sword strikes the opponent's metal faceplate or metal vest, the sword (i.e., the fencing weapon) and the opponent's fencing equipment (including hand lines, head lines, cross lines, and referee's equipment) form a circuit loop to detect a valid hit.

[0053] The core components of the circuit include the sword, hand line, metal faceplate, head line, metal vest, main wire, and referee's device. The sword blade and handplate are both conductive and serve as part of the circuit. The hand line has three ports, connecting to the sword, metal vest, and main wire. Both the metal faceplate and metal vest are conductive; a strike to either creates a circuit, illuminating the referee's device. The head line connects the metal faceplate and metal vest, ensuring they are at the same electrical potential. The main wire connects the hand line's connector to the referee's device, transmitting electrical signals. The referee's device detects strikes and displays which strike was valid.

[0054] The fencing circuit works by closing the circuit when the tip or blade of the sword contacts the opponent's metal faceplate or vest. Current flows through the sword, the faceplate, or the vest, and then back to the referee's device via a main wire. The device detects the current flow, determines which fencer made a valid hit, illuminates a light to indicate this, and records the score.

[0055] Building upon this, sensors on the hand and head lines further optimize the fairness of the competition. These sensors detect line status, triggering photoelectric alarms when connections are broken, lines are not properly attached, or there is poor contact. Unlike ordinary current sensors, which only alert when the circuit is connected, the sensors in this embodiment alarm even when the circuit is disconnected, using both flashing and audible alerts. This allows referees standing in front of or to the side of the athlete to promptly detect the anomaly and interrupt the match.

[0056] The workflow of the fencing scoring system will be described in detail below.

[0057] Before the competition begins, athletes don their metal vests and metal face shields. One end of the hand line is connected to the fencing weapon via a weapon connector, while the other end has a first branch connected to the vest via a hand line clamp, and a second branch connected to a cable reel via a main cable, forming a complete circuit. Simultaneously, one end of the head line is secured to the vest via a cable clamp, and the other end is connected to the face shield via another cable clamp. After the athletes don their equipment, referees or the event management system can detect the connection status using sensor modules to ensure all connections are functioning correctly.

[0058] During the competition, the handline sensor module monitors the connection status between the handline and the metal vest in real time. If the handline clamp accidentally loosens or falls off, causing the connection between the handline and the metal vest to break, the handline sensor module will detect the abnormality and immediately generate an alarm signal. This alarm signal can be emitted optically by LEDs on the metal vest or metal facet, or sounded by the acoustic alarm module of the referee's device, or even wirelessly transmitted to the referee's terminal to remind the referee to check the equipment connection status via vibration feedback.

[0059] Meanwhile, the headline sensor module is responsible for monitoring the connection status between the headline and the metal faceplate and metal suit. The headline sensor module can be located in the middle of the headline, and can also include a first sensor and a second sensor, respectively integrated into the clamps at both ends.

[0060] If the headline clamp becomes loose or detached during the match due to external force, the headline sensor module will detect the abnormal closure of the clamp, determine that the connection is broken, and generate a second alarm signal. Similar to the first alarm signal, this signal can also be used to alert the referee and athlete via an LED, an acoustic alarm module, or wireless vibration feedback.

[0061] In different embodiments, the sensor module can employ different types of sensors to improve detection accuracy and adapt to different connection methods. For example, if a current sensor is used, a disconnection can be determined when the current of the clamping component falls below a preset threshold, thereby triggering an alarm signal. If a Hall effect sensor is used, the system can determine that the magnetic locking structure has loosened when the magnetic flux of the clamping component falls below a preset threshold, thus issuing an alarm. For clamping components using strain sensors or pressure sensors, the system can determine whether loosening has occurred based on changes in deformation or clamping force, and trigger corresponding alarm signals accordingly. In addition, mechanical switches can be used to directly detect the closed state of the clamping component; when it is detected that it is not in the correct closed position, an alarm can be triggered immediately.

[0062] Using the methods described above, fencing protective gear can continuously monitor the status of key connections throughout the competition, ensuring that the equipment remains in a normal connection state at all times. When any connection abnormality occurs, the system can quickly identify it and issue an alarm, reminding athletes or referees to adjust the equipment in a timely manner, avoiding misjudgments or competition interruptions due to equipment connection failures, thereby improving the fairness, reliability, and safety of the competition.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
