Description

Technical Field

[0001] The invention relates to the technical field of Taekwondo kicking training, in particular to an intelligent Taekwondo kicking training device based on dynamic resistance regulation. Background Art

[0002] Early Taekwondo training devices were mostly static physical targets, such as fixed sandbags and foot targets, which could only provide simple hitting targets. The training process was boring and monotonous, and it was difficult to simulate the complex situations in actual combat. With the development of technology, some movable targets have gradually appeared, such as suspended mobile targets and track-type mobile targets, which have increased the difficulty and fun of training to a certain extent, but there are still great limitations in resistance adjustment and intelligent feedback. In recent years, with the rapid development of sensor technology, intelligent control technology and mechatronics technology, intelligent training equipment has begun to emerge in the field of sports training, providing technical support for the innovation of Taekwondo training devices, making it possible to develop training devices with dynamic resistance adjustment and intelligent feedback functions.

[0003] The existing traditional kicking training devices have relatively simple functions and cannot dynamically adjust the training difficulty and resistance according to the real-time performance of the athletes. It is difficult to meet the diversified and personalized needs of modern Taekwondo training. The targets of existing training devices are mostly fixed at specific angles and positions and cannot be flexibly adjusted.

[0004] Therefore, in view of the above problems, an intelligent Taekwondo kicking training device based on dynamic resistance adjustment is proposed. Summary of the invention

A nut block is arranged on the top of the worm gear, the side of the nut block is fixedly connected with a top support shell, and a first chute is opened inside the top support shell.

[0007] Preferably, the threaded rod forms a rotational structure with the bottom support shell through the second bearing, and the worm forms a rotational structure with the bottom support shell through the first bearing.

[0009] Preferably, the first motor forms a transmission structure with the threaded rod through the worm and the worm gear, and the worm and the worm gear are meshed with each other.

[0010] Preferably, the dynamic resistance adjustment component includes an installation box, a control unit is fixedly connected to the bottom of the installation box, a connecting wire is fixedly connected to the side of the control unit, and a second motor is fixedly connected to the end of the connecting wire. A gear is fixedly connected to the end of the first motor, a rack is meshed on the side of the gear, and a connecting piece is fixedly connected to the end of the rack. A pressure regulating valve is arranged at the end of the connecting piece, and a hydraulic cylinder is fixedly connected to the end of the pressure regulating valve.

[0011] Preferably, the second motor forms a transmission structure with the rack through the gear, and the gear and the rack are meshed with each other. The rack, the connecting piece, and the pressure regulating valve are arranged with their horizontal central axes coinciding, and the pressure regulating valve and the hydraulic cylinder form a communication structure.

[0012] Preferably, a displacement sensor and a pressure sensor are arranged inside the hydraulic cylinder, the displacement sensor and the pressure sensor are electrically connected to the control unit, and the control unit is electrically connected to the second motor through the connecting wire.

[0013] Preferably, the training hitting component includes an outer decorative surface, an internal support layer is arranged on one side of the outer decorative surface, and a metal support layer is arranged on the other side of the internal support layer.

[0014] Preferably, the outer decorative surface and the internal support layer form an adhesive structure, and the material of the outer decorative surface is set as high-density foam plastic material.

[0015] Preferably, the internal support layer and the metal bracket layer form an adhesive structure, and the material of the internal support layer is set as fiber-reinforced composite material.

[0016] The advantages of the present invention are as follows:

[0017] 1. By providing a height adjustment component, the threaded rod forms a rotating structure with the bottom support shell through the second bearing, and the worm forms a rotating structure with the bottom support shell through the first bearing. This design provides a stable rotating basis for the entire height adjustment component. The use of bearings effectively reduces the friction of the threaded rod and the worm during rotation, reduces the wear of components, and extends the service life of the device. At the same time, the stable rotating structure ensures that power can be transmitted smoothly during height adjustment, avoiding unstable phenomena such as jamming and shaking, and ensuring the safety of the device during training. For example, in multiple training scenarios of quickly adjusting the height, this structure can still maintain a good operating state and will not cause the adjustment to fail due to excessive friction. The first motor forms a transmission structure with the threaded rod through the worm and the worm gear, and the worm and the worm gear are meshed with each other. This transmission method utilizes the deceleration and torque-increasing characteristics of the worm and worm gear mechanism, enabling the small torque of the first motor to be converted into a larger driving torque of the threaded rod, realizing the stable lifting of the top support shell. At the same time, the threaded structure formed by the threaded rod and the nut block further ensures the accuracy of the lifting. Athletes or coaches can precisely adjust the height of the training hitting component by controlling the rotation of the first motor according to training needs. Whether it is for athletes of different heights or simulating attack targets at different heights in actual combat, it can be quickly and accurately adjusted in place, greatly improving the adaptability and flexibility of training. The precise lifting function achieved by the height adjustment component enables the training device to meet the needs of athletes of different heights and different training stages. For adolescent athletes, the training hitting component can be lowered to facilitate basic kicking action training; for adult professional athletes, it can be raised to simulate more difficult actual combat attack scenarios. This personalized height adjustment allows athletes to maintain the correct posture and force application method during training, avoiding action deformation caused by inappropriate device height, thereby improving training effects and reducing the risk of injury.

[0018] 2. The present invention is provided with a dynamic resistance adjustment component. The displacement sensor and pressure sensor arranged inside the hydraulic cylinder are electrically connected to the control unit, forming a complete closed-loop control system. When an athlete kicks the training striking component, the hydraulic cylinder is stressed, resulting in changes in displacement and pressure. The displacement sensor and pressure sensor collect these data in real time and transmit them to the control unit. The control unit compares and analyzes the actual hydraulic cylinder resistance data collected with the preset training resistance parameters. If there is a deviation, it issues an instruction to the second motor through the connection line to adjust the transmission of the gear and rack, changing the opening degree of the pressure regulating valve, thereby precisely adjusting the resistance of the hydraulic cylinder. This closed-loop control mechanism can effectively eliminate the resistance adjustment errors caused by mechanical wear, environmental factors, etc., ensuring that the resistance during the training process always remains at the set precise value, providing a stable and expected training intensity for the athlete. The displacement sensor and pressure sensor can monitor the working state of the hydraulic cylinder in real time and detect abnormal situations in a timely manner. For example, when the athlete kicks with too much force, causing the pressure of the hydraulic cylinder to exceed the safety threshold, the sensor quickly feeds back the data to the control unit, and the control unit immediately controls the second motor to reduce the speed and decrease the resistance of the hydraulic cylinder to prevent injury to the athlete due to excessive resistance and ensure training safety. At the same time, through the long-term recording and analysis of the sensor data, coaches and athletes can clearly understand the force output, resistance changes, etc. during the training process and evaluate the training effect. For example, judge the force growth trend of the athlete at different training stages based on the pressure sensor data, and analyze the effectiveness of the kicking action based on the displacement sensor data, so as to adjust the training plan targeted and improve the scientificity and effectiveness of the training. Based on the data collected by the sensors, the control unit can dynamically adjust the training resistance according to the real-time performance of the athlete to achieve adaptive training. For athletes in the initial stage of training, the system can automatically set a lower initial resistance according to their force level and technical proficiency, and gradually increase the resistance as the training progresses according to the progress feedback by the sensor, ensuring that the training difficulty improves synchronously with the athlete's ability. For high-level athletes, during high-intensity training, the sensor captures the subtle changes in kicking force and speed in real time, and the control unit adjusts the resistance in a timely manner to simulate a more complex and changeable actual combat resistance environment, such as simulating the confrontation resistance under different defensive intensities of opponents, making the training closer to actual combat, further tapping the potential of the athlete, and providing a highly personalized training experience for each athlete to improve the training effect.

[0019] 3. The present invention is provided with a protection component. The outer decorative surface is made of high-density foam plastic and forms a glued structure with the internal support layer. High-density foam plastic has good elasticity and cushioning performance. When an athlete kicks or strikes the training striking component, the outer decorative surface can effectively absorb the impact force, reduce the reaction force on the athlete's foot, and lower the risk of foot injuries caused by excessive kicking force. For example, in high-intensity kicking training, the high-density foam plastic outer layer can convert part of the impact force into its own deformation energy, making the athlete's foot feel a soft contact instead of a rigid impact. At the same time, the glued structure ensures that the outer decorative surface is tightly combined with the internal support layer and is not easily detached during long-term use, ensuring the continuity of the buffering function. The internal support layer is made of fiber-reinforced composite material and is glued to the metal support layer. Fiber-reinforced composite material has the characteristics of high strength and high modulus, and can provide reliable structural support for the entire training striking component. When an athlete kicks, it can effectively disperse the impact force and avoid structural damage caused by excessive local stress. For example, when an athlete uses a large force for a back kick, the internal support layer of the fiber-reinforced composite material can evenly disperse the impact force to the metal support layer, preventing dents or damages. In addition, its stable performance can also ensure that the training striking component still maintains its shape after multiple kicks, maintaining the accuracy and consistency of training.

[0032] Please refer to Figure 5The intelligent taekwondo kicking training device based on dynamic resistance adjustment shown in the figure, the training hitting component 3 includes an outer decorative surface 301, an internal support layer 302 is arranged on one side of the outer decorative surface 301, and a metal bracket layer 303 is arranged on the other side of the internal support layer 302; the outer decorative surface 301 and the internal support layer 302 form an adhesive structure, and the material of the outer decorative surface 301 is set as high-density foam plastic material; the internal support layer 302 and the metal bracket layer 303 form an adhesive structure, and the material of the internal support layer 302 is set as fiber-reinforced composite material.

[0033] Working principle: First, the height of the device can be adjusted according to one's own height and training needs. The height adjustment component 1 plays a role. The first motor 111 is started, and the first motor 111 drives the worm 102 to rotate. Since the worm 102 is rotationally connected to the bottom support shell 101 through the first bearing 103, the stability of rotation is ensured. The rotating worm 102 meshes with the worm wheel 105, transmits power to the worm wheel 105, and then drives the threaded rod 106 to rotate. The threaded rod 106 is rotationally connected to the bottom support shell 101 through the second bearing 104 to ensure its stable rotation. When the threaded rod 106 rotates, the nut block 107 that forms a threaded structure with it moves linearly on the threaded rod 106, and the top support shell 110 fixedly connected to the side of the nut block 107 rises and falls accordingly. The first chute 109 inside the top support shell 110 provides guidance for the slider 108 to ensure a smooth lifting process, thereby realizing the flexible adjustment of the height of the training hitting component 3.

[0034] After the height adjustment is completed, the athlete starts to kick the training hitting component 3. The outer decorative surface 301 of the training hitting component 3 is made of high-density foam plastic material and is adhesively connected to the internal support layer 302, which can effectively buffer the impact force when the athlete kicks and protect the athlete's feet; the internal support layer 302 is made of fiber-reinforced composite material and is adhesively connected to the metal bracket layer 303, providing reliable structural support for the component, dispersing the impact force, maintaining the stable shape of the component, and ensuring the accuracy and consistency of the training.

[0035] During the kicking process, the dynamic resistance adjustment component 2 works in real time to achieve dynamic adjustment of the resistance. When the athlete kicks the training striking component 3, the force is transmitted to the hydraulic cylinder 209. The displacement sensor and pressure sensor inside the hydraulic cylinder 209 collect displacement and pressure data in real time and transmit the data to the control unit 204. The control unit 204 analyzes and processes the data, compares it with the preset training resistance parameters. If there is a deviation, it issues an instruction to the second motor 203 through the connection line 202. After receiving the instruction, the second motor 203 drives the gear 205 to rotate. The gear 205 meshes with the rack 206, converting the rotational motion of the gear 205 into the linear motion of the rack 206. Since the horizontal central axes of the rack 206, the connecting piece 207, and the pressure regulating valve 208 are coincidentally arranged, the linear motion of the rack 206 can be accurately transmitted to the pressure regulating valve 208. By changing the opening degree of the pressure regulating valve 208, the flow rate and pressure of the hydraulic oil in the hydraulic cylinder 209 are adjusted, thereby achieving dynamic adjustment of the training resistance. For example, when the athlete's kicking force increases, the sensor data shows changes in pressure and displacement. The control unit 204 controls the second motor 203 to increase the rotation speed, causing the rack 206 to move, increasing the opening degree of the pressure regulating valve 208, and increasing the resistance of the hydraulic cylinder 209. When the kicking force decreases, the resistance is reduced conversely to meet the personalized needs under different training intensities.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
