Billiard cue straightness and hitting point precision dynamic feedback training device

Abstract

This utility model relates to a dynamic feedback training device for billiards cueing straightness and striking point accuracy, belonging to the technical field of sports training equipment. Addressing the lack of real-time feedback in traditional billiards training, the device includes: a base (1) with a through-type cue ball cavity (2); a dynamic feedback system consisting of a thin rope (3) fixed to the upper edge of the back of the cavity, a vertically suspended counterweight metal ball (4), and a metal plate (5) embedded in the top surface of the base; and horizontal through-type cavities (6) at the center of both sides of the base. During training, the cue stick is inserted into the horizontal cavity to calibrate the cueing straightness. After striking the center of the counterweight metal ball, the accuracy of the striking point is judged based on the metallic collision sound, and the offset direction is visually analyzed through the pendulum trajectory. The innovation lies in utilizing the synergistic mechanism of mechanical physical collision acoustic feedback and pendulum motion trajectory visual feedback to achieve dual training functions of cueing straightness calibration and dynamic detection of striking point accuracy.

Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically a dynamic feedback training device for training the straightness of the cue stroke and the accuracy of the striking point in billiards. Background Technology

[0002] Existing billiards training equipment has the following drawbacks:

[0003] 1. The single-function design cannot simultaneously achieve the calibration of the cue stick straightness and the training of the accuracy of the cue ball hitting point. For example, the track constraint scheme of patent CN202020427994.6 has the problem of the cue stick tilting due to the lack of constraint at the upper end; 2. The lack of a real-time motion feedback mechanism means that the training effect depends on subjective judgment.

[0004] 3. Electronic sensor solutions are costly and complex to maintain;

[0005] 4. Lacks a realistic impact feel during the hitting process. Summary of the Invention

[0006] I. Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a mechanical dynamic feedback training device, which focuses on solving the following problems: 1. The problem of correcting non-linearity of the rod trajectory;

[0008] 2. Visual detection of cue ball striking point offset;

[0009] 3. Real-time physical feedback of training results;

[0010] 4. It simulates the realistic impact of hitting the ball.

[0011] II. Technical Solution

[0012] The device includes the following structural features:

[0013] 1. Solid cuboid base (1), with dimensions of 160mm×57mm×60mm;

[0014] 2. Cue ball simulation unit: A cylindrical cavity (2) extending from the front to the back of the base (1), with a diameter of 57mm; 3. Dynamic feedback system:

[0015] - Fix one end of a thin rope (3) at the edge directly above the center point on the back of the cavity (2);

[0016] - The other end of the thin rope (3) is vertically suspended by a 10mm diameter counterweight metal ball (4), and the center point of the counterweight metal ball (4) is at the same height as the center point of the cavity (2);

[0017] - A metal sheet (5) with a length of 30mm, a width of 1mm, and a height of 2mm is provided at the center of the top surface of the base (1), with the extension direction perpendicular to the length direction of the base;

[0018] 4. Straightness training channel: The left and right sides of the base (1) are symmetrically opened with horizontally penetrating cylindrical cavities (6) with a diameter of 15mm.

[0019] III. Beneficial Effects

[0020] 1. Step-by-step training mechanism: Basic training on the straightness of the stroke is achieved through the constraint of the cavity (6), and advanced precision training is achieved by hitting the counterweight metal ball (4);

[0021] 2. Real-time physical feedback: The collision between the counterweight metal ball (4) and the metal plate (5) produces a sound, instantly determining the accuracy of the shot;

[0022] 3. Realistic feel of hitting the ball: When the cue stick hits the counterweight metal ball (4), there is feedback from the interaction force, which greatly simulates the feeling of hitting the ball in the actual billiards stroke;

[0023] 4. Visualization of error direction: The yaw trajectory of the counterweight metal ball (4) can be used to intuitively determine the direction of the strike point offset and the direction of the stroke.

[0024] 5. Zero electricity dependence: The purely mechanical structure reduces manufacturing costs and requires no maintenance. Attached Figure Description
