Description

Technical Field

[0001] This utility model relates to a throwing training device with motion monitoring function, belonging to the technical field of sports training devices. Background Technology

[0002] Throwing sports such as javelin, discus, and shot put all require training with equipment. Javelin throwing, for example, is a relatively complex multi-axis rotational sport. Its complete technique involves a pre-running motion with the javelin in hand, followed by a throwing step to gain momentum, and then an explosive final push along the javelin's longitudinal axis, launching it over the shoulder. Javelin throwing is a specialized sport; throwing techniques and power generation require continuous training to achieve greater distances. Currently, javelin training is mostly conducted in open fields. Due to the inherent risks of javelin throwing and the specific requirements for the training area, training is not permitted in areas with people. Therefore, the limited availability of suitable venues restricts the sport's popularity, and javelin is increasingly absent from school sports programs.

[0003] Most existing throwing training devices are mechanical designs, lacking throwing data monitoring devices and data analysis systems. This makes it impossible to detect the motion state and throwing force during throwing training, resulting in low intelligence and limited use. Furthermore, their large footprint and high risk make them unsuitable for widespread use in physical education. Therefore, designing a throwing training device with motion monitoring capabilities is an urgent need. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a throwing training device with motion monitoring function, which solves the problems existing in the prior art.

[0005] The throwing training device with motion monitoring function of this utility model includes a motion support frame and a height adjustment slide. A motion axis is connected between the motion support frame and the height adjustment slide. The motion axis is inclined and a motion handle is sleeved on the motion axis. The motion handle is a pipe-type slide tube that passes through the motion axis and can slide along the motion axis. The motion handle has a built-in wireless motion posture monitoring module for monitoring the acceleration of the motion handle. The wireless motion posture monitoring module is connected to a microcontroller, and the microcontroller is connected to a wireless transmission module. The wireless transmission module enables data communication with an external mobile terminal.

[0006] Furthermore, a pressure detection module is provided at the end of the motion axis, and the pressure detection module is electrically connected to the microcontroller.

[0007] Furthermore, the motion monitoring module includes a motion attitude sensor, which internally has a 3-axis gyroscope and a 3-axis accelerometer. The attitude sensor is connected to a microcontroller through an attitude measurement circuit, and the microcontroller is connected to a data storage device.

[0008] Furthermore, the pressure detection module employs a pressure detection sensor, which uses a piezoelectric ceramic sheet. The pressure detection sensor is connected to the microcontroller via a pressure detection circuit.

[0009] Furthermore, the microcontroller is also connected to a vibration detection circuit, which consists of a vibration sensor and a signal conditioning circuit. The vibration detection circuit detects vibration signals and transmits them to the microprocessor.

[0010] Furthermore, the wireless transmission module is a Bluetooth transmission module, and the mobile terminal is a mobile phone or a PC.

[0011] Furthermore, a shock absorber is installed at the end of the motion shaft.

[0012] Furthermore, it also includes fasteners and connectors. One end of the motion shaft is connected to the motion support frame via the connector, and the other end of the motion shaft is connected to the height adjustment slide via the fasteners. The motion support frame and the height adjustment slide are placed vertically on the ground. A base is connected below the motion support frame and the height adjustment slide. The base is pre-embedded in the ground for fixation. The entire throwing training device forms an independent installation assembly.

[0013] Furthermore, the motion support frame is inverted L-shaped, with the horizontal part of the motion support frame installed perpendicular to the wall. The outer side of the vertical part of the motion support frame is connected to a height adjustment slide, which is fixed to the wall by fixing screws. The motion shaft is installed between the horizontal and vertical parts of the motion support frame, and the entire throwing training device forms a suspended installation assembly at a 90° angle to the wall.

[0014] Furthermore, the motion support frame has an inverted L-shaped structure, with both the horizontal and vertical sections of the motion support frame installed parallel to the wall. The outer sides of both the horizontal and vertical sections of the motion support frame are connected to height adjustment slides. The motion shaft is installed between the horizontal and vertical sections of the motion support frame, and the entire throwing training device forms a wall-mounted installation assembly parallel to the wall.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention relates to a throwing training device with motion monitoring function. The device features a motion handle that runs along a motion axis and can slide along it. The trainee holds the handle and throws the object along the axis, simulating the throwing of javelins, medicine balls, softballs, etc. A wireless motion posture monitoring module is built into the handle, which monitors the handle's acceleration in real time and calculates its speed. Furthermore, a pressure detection device is installed at the end of the motion axis. When the trainee throws the handle and it slides to the end of the axis, the handle impacts the pressure detection device, and the magnitude of the impact force is calculated. The trainee's throwing performance is judged by combining the release speed of the handle and the magnitude of the impact force.

[0017] This device offers three different installation options: freestanding, suspended, and wall-mounted, minimizing floor space usage. All three installation methods allow for height adjustment of the trainer via a height-adjustable slide and angle adjustment of the motion axis to achieve the optimal release angle. Data is collected and analyzed in the background by moving the handle along the motion axis, generating big data. Individual data analysis identifies weaknesses that trainees need to improve, providing key data for users. Data comparison provides strong support for targeted improvements to training plans and adjustments to training intensity, laying the foundation for improved performance and training quality.

[0018] This device not only enables users to quickly master the complete technical movements of throwing events, but also provides teachers with various scientific and precise data for teaching and students with learning. Through the use of this intelligent trainer, more throwing enthusiasts can perfect their throwing movements and improve their athletic performance more quickly. This device can be used to train for shot put and softball (excluding javelins) by changing the training handles, thus solving the problems existing in current technology.

The motion handle 4 is a pipe-type slide tube that passes through the motion shaft 3 and can slide along the motion shaft 3. The motion handle 4 has a built-in wireless motion posture monitoring module for monitoring the acceleration of the motion handle 4.

The attitude sensor contains an IIC interface, which can be used to connect an external magnetic sensor. Utilizing its built-in digital motion processor hardware acceleration engine, it outputs complete 9-axis fusion calculation data to the application through the main IIC interface.

[0033] like Figure 5 As shown, the pressure detection module 2 uses a pressure detection sensor, which is a piezoelectric ceramic sheet. The pressure detection sensor is connected to the microcontroller through a pressure detection circuit.

The attitude sensor U3 is connected to the Bluetooth module U6 to transmit the monitored motion data. The motion attitude monitoring module integrates two memories: FRAM data memory and EEPROM. FRAM stores the motion monitoring data during the motion process, and EEPROM is used to store system parameters.

[0039] Meanwhile, the motion handle 4 has a built-in lithium battery that powers the entire circuitry, so the motion monitoring module needs charge / discharge management capabilities. This module uses the LTC4055. These devices manage and limit the total current used for operation by the USB peripheral and battery charging.
