Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sports training auxiliary equipment, in particular to a training monitoring device for billiards. BACKGROUND

[0002] Billiards is a sport with high requirements for precision, stability and force control of hitting action. Currently, athletes mainly rely on subjective experience observation of coaches or post-viewing training videos to analyze and improve technical actions during training. This method has obvious defects: first, it lacks objective and quantitative data as support, and the judgment standard is subjective and not accurate enough; second, the feedback is lagging, which cannot provide instant prompts for athletes at the moment of hitting action, which is not conducive to the immediate correction of incorrect actions and the formation of muscle memory; finally, it is difficult to systematically store, manage and deeply analyze long-term and large amounts of training data, so it is difficult to develop scientific and individualized training plans.

[0003] To solve the above problems, some intelligent billiard cues integrated with sensors have appeared in the prior art. However, most of these solutions directly embed sensors inside the cue. This integrated design results in high cost and poor universality. Athletes must purchase specific and expensive intelligent cues to use related functions, which cannot be adapted to their personal cues that they are already accustomed to and familiar with, which greatly limits its popularization and application. Therefore, there is an urgent need in the field for a detection device that is low in cost, strong in universality, can be conveniently installed on existing standard billiard cues, and can provide objective and real-time data feedback. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide an external intelligent billiard cue motion detector and system. The detector is installed at the tail of any existing billiard cue through a standardized interface, has strong universality, and can accurately collect, real-time prompt and remotely analyze key parameters such as cue motion trajectory, inertia, hitting force, etc. without the need to replace the cue, effectively assisting athletes in scientific and data-based training.

[0005] To achieve the above purpose, the present application adopts the following technical solution: an external intelligent billiard cue motion detector, comprising a shell, a central processing unit, a motion sensor module, a prompt module, a wireless communication module and a power module. One end of the shell is provided with a standard screw interface for screw connection with the lengthened handle screw hole at the tail of the billiard cue, so that the detector and the billiard cue form a locked whole. The motion sensor module, the prompt module, the wireless communication module and the power module are all arranged inside the shell or integrated with the shell, and are electrically connected with the central processing unit.

[0006] Furthermore, the motion sensor module includes at least a MEMS accelerometer and a MEMS gyroscope for collecting motion data of the billiard cue, the motion data including the motion trajectory and inertia in three-dimensional space.

[0007] Furthermore, the prompting module includes at least a buzzer and / or a vibration motor for issuing auditory or tactile prompting signals according to the instructions of the central processing unit.

[0008] Furthermore, the wireless communication module includes a Bluetooth module and / or a Wi-Fi module for data interaction with external smart terminals or cloud servers.

[0009] Furthermore, the power module is a button battery, which is detachably installed inside the housing.

[0010] Furthermore, the detector also includes a weighing chip electrically connected to the central processing unit, used to sense and measure the force at the moment of impact or the static weight of the cue stick.

[0011] This invention also provides a motion monitoring system, including the aforementioned external intelligent billiard cue motion detector, an intelligent terminal with a supporting application installed, and a cloud server. The intelligent terminal is connected to the detector via a wireless communication module, used to receive, display, and analyze motion data, and can send parameter adjustment commands to the detector. The cloud server is used to store and analyze data from the intelligent terminal or the detector.

[0012] The present invention also provides a billiards training method using the above-mentioned motion monitoring system.

[0013] The beneficial effects of this invention are as follows: 1. Versatility and Low Cost: The standard screw interface design allows for easy installation on any billiard cue with a standard screw hole, achieving a separate design from the cue. Users do not need to purchase a dedicated smart cue, significantly reducing usage costs and ensuring widespread adoption. 2. Accurate and Comprehensive Data: Integrating a high-precision MEMS accelerometer, gyroscope, and optional weighing chip, it can collect key biomechanical parameters such as the cue's trajectory, speed, acceleration, angular velocity, and striking force from all angles and dimensions. 3. Real-time Feedback Mechanism: The built-in buzzer and vibration motor provide immediate auditory or tactile cues to athletes when errors are detected (such as incorrect stroke or excessive wobbling), enabling instant correction during training and improving training efficiency. 4. Intelligent Data Analysis and Management: Through collaboration with a mobile app and cloud server, it enables data visualization, long-term tracking, in-depth analysis, and the generation of personalized training plans, forming a complete digital training solution. 5. Excellent user experience: The device has a compact structure, small size, and light weight. After installation, it has minimal impact on the original weight balance of the club and the athlete's hitting feel, achieving seamless intelligent monitoring. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 and Figure 2 This invention provides an external billiard cue intelligent motion detector, the core components of which are housed within a housing (1). The housing 1 is preferably made of lightweight and sturdy materials such as ABS engineering plastic or aluminum alloy. One end of the housing 1 is designed with a standard screw interface 11. The specifications of this interface (such as metric or imperial) conform to the general standards of the International Billiards Federation, and it can be directly screwed into the extended handle screw hole at the end of most billiard cues 300, achieving a quick and stable connection. This ensures that the detector and the cue remain rigidly integrated during movement, thereby guaranteeing the accuracy of data acquisition. This interface can be equipped with an adapter to achieve the conversion and installation of different screw interfaces on different cues.

[0020] Inside the housing (1), the following are integrated: - Central processing unit (2): As the control core, it uses a low-power microprocessor to schedule the operation of each sensor, perform preliminary data filtering and fusion calculation, control the response of the prompt module, and manage wireless communication. - Motion sensor module (3): The core includes a MEMS three-axis accelerometer and a MEMS three-axis gyroscope. They are used to measure the linear acceleration and rotational angular velocity of the cue stick in three axial directions, respectively. By integrating and calculating the attitude of these raw data, the motion trajectory of the cue stick can be reconstructed, and key indicators such as speed and straightness of the cue stick can be calculated. - Prompt module (4): Includes a miniature buzzer 41 and a miniature vibration motor 42. The central processing unit 2 can compare the motion parameters calculated in real time with the threshold preset by the mobile APP (such as the maximum allowable lateral acceleration). Once the threshold is exceeded, the buzzer 41 will sound or the vibration motor 42 will vibrate immediately to achieve real-time feedback. - Wireless communication module (5): Mainly uses a low-power Bluetooth module 51 to achieve a stable connection with the smart terminal 100, for uploading data and receiving configuration instructions. A Wi-Fi module 52 can also be integrated as needed for direct internet connection in specific environments. - Power module (6): In this embodiment, a replaceable button battery 61 (such as CR2032) is used for power supply. The battery compartment is designed on the side wall of the housing for easy replacement by the user. - Weighing chip (7) (preferred embodiment): A miniature strain gauge sensor is used and installed at the root of the helical interface 11 to sense the minute stress change transmitted by the club tail at the moment of impact. After calibration, it can be converted into the impact force. - Storage unit (8) (preferred embodiment): Built-in small-capacity flash memory can temporarily cache data when the wireless connection is interrupted to ensure data integrity.

[0021] Please see Figure 3 The motion monitoring system of the present invention includes the aforementioned detector, a smart terminal 100 (such as a smartphone), and a cloud server 200. A dedicated APP on the smart terminal 100 has functions such as device management, data visualization, training plan creation, and parameter setting. The cloud server 200 is responsible for storing massive amounts of data, performing in-depth analysis based on artificial intelligence algorithms (such as building expert motion models for comparison), and providing personalized training suggestions for different users.

[0022] The workflow of this invention is as follows: The user installs the detector on the golf club, connects to the device via an app, and sets training parameters. During training, data from each shot is collected and processed in real time. If the movement is not standard, the detector will immediately alert the user through vibration or sound. Simultaneously, detailed data is sent to the app for recording and graphical display. After training, the user can review and analyze the data via the app, or a detailed training report and suggestions for improvement can be generated by the cloud server.

[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
