Description

Technical Field

[0001] This invention relates to the field of ice hockey training equipment technology, specifically to a gliding step training device for ice hockey defense training and its usage method. Background Technology

[0002] In ice hockey, the gliding technique of defensive players is one of the core basic skills, which directly affects the defensive effect and the outcome of the game. Ice hockey defensive gliding is mainly based on lateral gliding, and it is necessary to take into account movement speed, change of direction flexibility, center of gravity stability and adaptability to confrontation. Therefore, the training requirements are extremely high in terms of specificity and professionalism.

[0003] Current ice hockey gliding training methods mostly employ traditional rink training or simple gliding devices, which have the following shortcomings: First, the training trajectory is fixed and cannot accurately adapt to the natural movement trajectory of ice hockey defensive lateral gliding, resulting in a disconnect between training effects and actual game scenarios; Second, there is a lack of effective guidance and adjustment mechanisms, making it difficult to simulate different defensive change-of-direction scenarios, resulting in a monotonous training environment; Third, it cannot accurately simulate the resistance encountered in a game, making the training intensity uncontrollable and unable to dynamically adapt to the trainee's level; Fourth, the posture detection accuracy is insufficient, making it impossible to capture the trainee's body posture data in real time and make accurate corrections, making it difficult for trainees to recognize their own movement defects; Fifth, the training data lacks systematic recording and review analysis, which is not conducive to the continuous optimization of training effects.

[0004] Therefore, there is an urgent need for a sliding step training device that can accurately adapt to the sliding step trajectory of ice hockey defense, simulate training in multiple scenarios, detect posture in real time, and dynamically adjust the training intensity, so as to solve many defects of existing training equipment and improve the scientificity and effectiveness of ice hockey defensive sliding step training. Summary of the Invention

[0005] To address the problems of mismatched trajectories, limited scenarios, uncontrollable resistance, inaccurate posture detection, and lack of training review in existing ice hockey gliding training devices, this invention provides a gliding training device and method for ice hockey defense training. This enables precise and multi-scenario training of ice hockey defense gliding, while also featuring real-time posture correction, dynamic intensity adjustment, and training data review functions, significantly improving training effectiveness.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sliding step training device for ice hockey defense training, comprising a sliding step platform module, a guide adjustment module, a resistance simulation module, a posture detection module, a central control module, and a display interaction module; the central control module is electrically connected to the sliding step platform module, the guide adjustment module, the resistance simulation module, the posture detection module, and the display interaction module respectively, so as to realize the coordinated operation of each module.

[0007] The sliding platform module includes a base and two sets of symmetrically arranged sliding units. Each set of sliding units includes an arc-shaped slide rail, a sliding seat, and an anti-slip pedal. The arc-shaped slide rail is fixed to the top surface of the base, with an arc range of 120°-150°, precisely adapting to the movement trajectory of the lateral sliding step in ice hockey defense, ensuring the standardization of training movements. The sliding seat slides in conjunction with the arc-shaped slide rail to ensure smooth sliding. The anti-slip pedal is fixed to the top of the sliding seat, and the upper surface of the anti-slip pedal has anti-slip textures to improve safety during training and prevent slipping. A pressure sensor is embedded in the surface of the anti-slip pedal, and the pressure sensor is connected to the central control module to collect data on the force distribution on the pedal when the trainee is standing, assisting in determining the center of gravity position.

[0008] The guide adjustment module includes a drive motor, a lead screw mechanism, a guide plate, and a drive component. The drive motor is fixed to the end of the base. The input end of the lead screw mechanism is connected to the output end of the drive motor. The guide plate is located between two sets of sliding units and is rotatably connected to the output end of the lead screw mechanism. The drive component is located on one side of the connection position between the guide plate and the lead screw mechanism. The drive motor is electrically connected to the central control module. The central control module controls the operation of the drive motor and the drive component to achieve adjustable height and tilt angle of the guide plate, thereby simulating different defensive change-of-direction scenarios.

[0009] The resistance simulation module includes an elastic pull rope, a tension sensor, and a winding device. The winding device is symmetrically fixed to the front surface of the base. One end of the elastic pull rope is connected to the winding device, and the other end is fixedly connected to the surface of the sliding seat. The tension sensor is connected in series with the elastic pull rope and is signal-connected to the central control module. The tension is adjusted by regulating the extension and retraction of the elastic pull rope through the winding device, thus simulating lateral resistance in defensive combat. The tension sensor collects tension data in real time and feeds it back to the central control module to ensure the accuracy of resistance control.

[0010] The posture detection module includes an inertial measurement unit and a high-definition camera. The inertial measurement unit is worn on the waist and legs of the trainee to accurately collect the trainee's body posture data. The high-definition camera is fixed above the sliding platform module to capture the trainee's sliding motion images in real time. Both the inertial measurement unit and the high-definition camera are connected to the central control module to achieve all-round and multi-dimensional detection of training posture.

[0011] The central control module includes a microprocessor and a data storage unit. The microprocessor receives data from pressure sensors, tension sensors, inertial measurement units, and high-definition cameras. After analysis and processing, it outputs control commands to the drive motor and the winding unit to achieve coordinated control of each module. The data storage unit is used to store training data and standard motion parameters, providing data support for training comparison and review.

[0012] The display interaction module includes a touch screen for displaying training parameters, real-time posture data, training progress, and standard movement comparison images. It also supports trainees to input personal parameters and training needs. The display interaction module is electrically connected to the central control module to realize human-computer interaction functions.

[0013] Furthermore, the inner side of the arc-shaped slide rail is provided with a guide groove, the cross-section of which is a convex structure. The side of the sliding seat is provided with a guide block that matches the guide groove. The guide block contains multiple rolling bearings. Through the cooperation between the guide groove and the guide block and the setting of the rolling bearings, the smoothness and stability of the sliding seat on the arc-shaped slide rail are improved, and the sliding resistance is reduced. A 5-8mm thick rubber buffer pad is provided above the anti-slip pedal to buffer and absorb shock, reducing the risk of joint injury to the trainee.

[0014] Furthermore, the guide adjustment module also includes an angle sensor, which is installed on the top of the guide plate to collect the tilt angle data of the guide plate in real time and feed it back to the central control module to achieve precise adjustment of the tilt angle of the guide plate. The tilt angle adjustment range is 0°-30°, which can cover various defensive change-of-direction scenario requirements.

[0015] Furthermore, the lead screw mechanism includes a threaded rod, a threaded sleeve, a guide rod, a guide sleeve, and a connecting plate. The threaded rod is connected to the output end of the drive motor. The threaded sleeve is threaded onto the surface of the threaded rod. The guide rod is disposed on both sides of the threaded rod. The guide sleeve is sleeved on the surface of the guide rod. The connecting plate is connected to the threaded sleeve and the guide sleeve via a fixing rod. A blind groove adapted to the rotating shaft of the guide plate is formed on the side of the connecting plate away from the threaded rod. The drive motor drives the threaded rod to rotate, causing the threaded sleeve to move along the threaded rod, thereby driving the connecting plate and the guide plate to move up and down, realizing the adjustment of the height of the guide plate. The cooperation between the guide rod and the guide sleeve ensures the stability of the movement of the connecting plate.

[0016] Furthermore, the driving component includes a servo motor, a gear, and a half-tooth disk. The servo motor is mounted on the surface of the connecting plate and located on one side of the connection between the guide plate and the lead screw mechanism. The servo motor is signal-connected to the central control module. The gear is connected to the output end of the servo motor. The half-tooth disk is fixedly mounted on one side of the guide plate and meshes with the gear. The servo motor drives the gear to rotate, which in turn drives the half-tooth disk to rotate, thereby causing the guide plate to rotate around the axis, thus achieving adjustment of the tilt angle of the guide plate with high precision.

[0017] Furthermore, the rewinder is electrically driven and electrically connected to the central control module. The tension adjustment range of the elastic draw rope is 5-30N, which can adapt to different training intensity requirements. The elastic draw rope is made of high-elasticity polyurethane material, which has good elastic recovery and durability.

[0018] The training method based on the above-mentioned ice hockey defense training gliding training device includes the following steps: S1: Parameter initialization: The trainee inputs personal height, weight and training level parameters through the display interaction module. The central control module calls the corresponding standard movement parameters and training intensity parameters in the data storage unit to automatically initialize the guide plate angle of the guide adjustment module and the initial tension of the resistance simulation module to ensure the training is targeted.

[0019] S2: Basic Sliding Step Training: The trainee stands on the anti-slip pedals of two sets of sliding step units and starts the training; the posture detection module collects the trainee's body posture data and sliding step movement images in real time, and the pressure sensor collects the force distribution data of the pedals; the central control module compares the collected real-time data with standard parameters, and if there is a posture deviation, it outputs a correction prompt through the display interaction module; at this time, the resistance simulation module maintains the initial tension to simulate basic sliding step training in a non-contact scenario. The training time is 5-10 minutes to solidify the trainee's basic sliding step skills.

[0020] S3: Change of Direction Slide Training: After the basic slide training is completed, the central control module outputs control commands to the guide adjustment module. The drive motor drives the guide plate to adjust to the preset tilt angle through the screw mechanism, simulating a defensive change of direction scenario. The trainee performs change of direction slide training along the arc-shaped slide rail and the direction defined by the guide plate. The posture detection module focuses on collecting the center of gravity transfer data at the moment of change of direction. The central control module adjusts the angle of the guide plate in real time according to the center of gravity transfer deviation, dynamically optimizes the training difficulty, and improves the trainee's change of direction slide ability.

[0021] S4: Counter-Slide Training: After the change-of-direction slide training is completed, the central control module outputs control commands to the resistance simulation module. The retractor adjusts the tension of the elastic rope to a preset level to simulate lateral resistance in defensive confrontation. The trainee completes a combination of lateral slide and change-of-direction slide movements under the action of resistance, and the tension sensor collects resistance data in real time. The central control module dynamically adjusts the tension according to the trainee's performance to ensure that the training intensity is matched with the trainee's level and improve the trainee's counter-slide ability.

[0022] S5: Training Review: After training, the central control module summarizes and analyzes the training data, generates a training report that includes indicators such as sliding speed, center of gravity shift, and movement compliance rate, and displays a comparison video of the training movement and the standard movement through the interactive display module; the training data can be transmitted to the mobile terminal for backup via the wireless communication unit, which is convenient for trainees to analyze and optimize the training plan later.

[0023] Furthermore, in step S2, the correction prompts include text prompts and voice prompts; when the trainee's center of gravity shift exceeds 5cm, or the knee bending angle deviates from the standard value by ±10°, the display interaction module issues a red warning and accurately marks the deviation location, making it easier for the trainee to quickly correct the movement.

[0024] Furthermore, in step S4, the training intensity is divided into three levels: beginner, intermediate, and advanced, corresponding to resistance forces of 5-10N, 10-20N, and 20-30N, respectively. When the trainee achieves a pass rate of more than 80% for the current level, the central control module automatically controls the resistance simulation module to upgrade to the next training level, thereby achieving a gradual increase in training intensity and improving training effectiveness.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: Precise adaptation of gliding trajectory: The gliding platform module adopts an arc-shaped gliding rail with an arc of 120°-150°, which precisely matches the natural movement trajectory of the lateral gliding step in ice hockey defense, ensuring the standardization and practicality of training movements and improving the fit between training and actual game scenarios.

[0026] Diverse training scenarios: The guide adjustment module enables precise adjustment of the guide plate height and tilt angle from 0° to 30°, simulating different defensive change-of-direction scenarios and meeting various training needs such as basic sliding steps and change-of-direction sliding steps, thus solving the problem of limited training scenarios in traditional devices.

[0027] Dynamically adjustable training intensity: The resistance simulation module uses an electric retractor and a high-elasticity polyurethane elastic rope to achieve precise adjustment of the tension within the range of 5-30N. It can also automatically upgrade the training level according to the trainee's performance, adapting to the needs of trainees of different levels. At the same time, it can simulate lateral resistance in defensive confrontation, improving the targeting and effectiveness of training.

[0028] Precise and efficient posture detection: The posture detection module combines an inertial measurement unit (worn on the waist and legs) and a high-definition camera to collect trainees' body posture data in all directions and multiple dimensions. The central control module compares and analyzes the data in real time, and provides precise corrections through text and voice prompts and red alerts, helping trainees quickly correct movement defects.

[0029] It features training review capabilities: the central control module can summarize and analyze training data, generate training reports that include indicators such as gliding speed, center of gravity shift, and movement compliance rate, and display comparison videos of movements. It also supports training data backup, which facilitates subsequent analysis and optimization of training programs by trainees, thereby improving the scientific nature of training.

[0030] High safety and stability: The anti-slip pedal is equipped with anti-slip texture and rubber cushioning pad, which not only ensures the anti-slip effect during training, but also plays a role in cushioning and shock absorption, reducing the risk of joint injury; the arc-shaped slide rail and the sliding seat are combined with convex guide grooves and guide blocks with rolling bearings, which improves the smoothness and stability of sliding.

It is fixed above the sliding platform module 1 by a bracket and is used to capture the trainee's sliding motion images in real time. Both the inertial measurement unit 41 and the high-definition camera 42 are connected to the central control module 5.

[0039] The central control module 5 includes a microprocessor 51 and a data storage unit 52. The microprocessor 51 is an STM32F407ZGT6 microcontroller, and the data storage unit 52 is an SD card module. The microprocessor 51 receives the collected data transmitted by the pressure sensor 124, the tension sensor 32, the inertial measurement unit 41, the high-definition camera 42, and the angle sensor 25. After analysis and processing, it outputs control commands to the drive motor 21, the servo motor 241, and the winding device 33. The data storage unit 52 is used to store training data and standard motion parameters.

[0040] It should be noted that the central control module 5 also includes a wireless communication unit, which supports wireless connection with mobile terminals.

It is used to display training parameters, real-time posture data, training progress and standard movement comparison images. It also supports trainees to input personal parameters and training needs. The display interaction module 6 is electrically connected to the central control module 5.

[0042] The specific implementation process of the training method based on the above-mentioned device is as follows: S1: Parameter initialization: The trainee inputs their height, weight and training level through the touch screen 61. The microprocessor 51 of the central control module 5 calls the corresponding standard motion parameters and training intensity parameters in the SD card, automatically controls the drive motor 21 and servo motor 241 to run, adjusts the guide plate 23 to the initial angle of 0° and the initial height of 30cm, and at the same time controls the rewinder 33 to adjust the initial tension of the elastic rope 31 to 5N.

[0043] S2: Basic Sliding Step Training: The trainee stands on the anti-slip pedals 123 of the two sets of sliding step units 12 with their feet shoulder-width apart and starts training via the touch screen 61; the inertial measurement unit 41 collects real-time data on the trainee's waist and leg posture, the high-definition camera 42 captures images of the sliding step movements, and the pressure sensor 124 collects data on the force distribution of the pedals; the microprocessor 51 compares the collected real-time data with standard parameters. If the trainee's center of gravity shift exceeds 5cm or the knee bending angle deviates from the standard value by ±10°, the touch screen 61 displays a red warning and accurately marks the deviation location, such as "center of gravity to the left" or "left knee bending angle too large", and at the same time issues a voice prompt through the voice module; at this time, the resistance simulation module 3 maintains an initial tension of 5N to simulate basic sliding step training in a non-contact scenario, and the training time is set to 8 minutes.

[0044] S3: Change of Direction Slide Training: After the basic slide training is completed, the microprocessor 51 outputs control commands to the guide adjustment module 2.

The servo motor 241 drives the gear 242 to rotate, driving the half-tooth disk 243 to rotate, adjusting the tilt angle of the guide plate 23 to 15°, simulating a defensive change of direction scenario. The trainee performs change of direction slide training along the direction defined by the arc-shaped slide rail 121 and the guide plate 23. The inertial measurement unit 41 and the high-definition camera 42 focus on collecting the center of gravity transfer data at the moment of change of direction. The microprocessor 51 adjusts the angle of the guide plate 23 in real time according to the center of gravity transfer deviation. When the deviation is large, the angle is adjusted to a smaller angle, and when the deviation is small, the angle is adjusted to a larger angle, dynamically optimizing the training difficulty.

[0045] S4: Counter-Slide Training: When the trainee's success rate in changing direction slides reaches over 80%, the microprocessor 51 outputs control commands to the resistance simulation module 3, and the retractor 33 adjusts the tension of the elastic rope 31 to 10N to simulate lateral resistance in defensive confrontation. The trainee completes a combination of lateral slides and changing direction slides under the action of resistance, and the tension sensor 32 collects resistance data in real time. The microprocessor 51 dynamically adjusts the tension according to the trainee's performance. When the success rate of the movement remains above 80%, the tension is automatically adjusted to 12N, upgrading the training level.

[0046] S5: Training Review: After training, the microprocessor 51 summarizes and analyzes the training data, generates a training report including indicators such as sliding speed, average speed, maximum speed, center of gravity offset, maximum offset, average offset, and movement compliance rate, and displays a comparison image of the training movement and the standard movement through the touch screen 61; the training data can be transmitted to the mobile phone for backup through the wireless communication unit of the central control module 5.

7. A method for practicing sliding steps in ice hockey defense training based on the sliding step training device for ice hockey defense training according to any one of claims 1-6, characterized in that: Includes the following steps: S1: Parameter initialization: The trainee inputs personal height, weight and training level parameters through the display interaction module. The central control module calls the corresponding standard movement parameters and training intensity parameters in the data storage unit to automatically initialize the guide plate angle of the guide adjustment module and the initial tension of the resistance simulation module. S2: Basic slide step training: The trainee stands on the anti-slip pedals of the two sets of slide step units and starts the training; The posture detection module collects real-time body posture data and sliding motion images of the trainee, while the pressure sensor collects force distribution data of the pedal. The central control module compares the collected real-time data with standard parameters. If there is a posture deviation, the display and interaction module outputs a correction prompt. At this time, the resistance simulation module maintains the initial tension to simulate basic sliding training in a non-contact scenario, with a training time of 5-10 minutes. S3: Change of direction sliding step training: After the basic sliding step training is completed, the central control module outputs control commands to the guide adjustment module, and the drive motor drives the guide plate to adjust to the preset tilt angle through the lead screw mechanism to simulate the defensive change of direction scenario; Trainees perform directional sliding steps along the arc-shaped slide rail and guide plate, and the posture detection module focuses on collecting the center of gravity transfer data at the moment of directional change. The central control module adjusts the angle of the guide plate in real time based on the deviation of the center of gravity transfer, dynamically optimizing the training difficulty. S4: Counter-Slide Training: After the change-of-direction slide training is completed, the central control module outputs control commands to the resistance simulation module. The retractor adjusts the tension of the elastic rope to a preset level to simulate lateral resistance in defensive confrontation. The trainee completes a combination of lateral slide and change-of-direction slide movements under the action of resistance, and the tension sensor collects resistance data in real time. The central control module dynamically adjusts the tension according to the trainee's performance to ensure that the training intensity is appropriate for the trainee's level. S5: Training Review: After training, the central control module summarizes and analyzes the training data, generates a training report that includes indicators such as sliding speed, center of gravity shift, and movement compliance rate, and displays a comparison video of the training movement and the standard movement through the display interaction module; the training data can be transmitted to the mobile terminal for backup through the wireless communication unit.
