[0001] This utility model relates to the field of data acquisition and analysis device technology, and in particular to a multi-dimensional data acquisition and analysis device based on street dance competition evaluation. Background Technology

[0002] In street dance competitions, traditional judging methods mainly rely on the judges' subjective observation and scoring. This method makes it difficult to comprehensively and accurately quantify and evaluate dancers' movements, rhythm, spatial utilization, and other multi-dimensional data. It is also easily influenced by factors such as the judges' personal preferences, which may lead to a certain degree of bias and uncertainty in the judging results.

[0003] Current AI-based data acquisition and analysis devices can solve the above problems, but they still have some shortcomings in use: for example, the acquisition device needs to be adjusted when debugging the device. Existing technologies mostly use universal adjustment to adapt to different angles. However, this structure is prone to wear and tear, and the contact becomes slippery after wear. Especially during the acquisition process, if the structure slips, it will cause inaccurate capture offset, affecting subsequent analysis. Therefore, a multi-dimensional data acquisition and analysis device based on street dance competition judging is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 This utility model provides a multi-dimensional data acquisition and analysis device based on street dance competition judging: such as Figure 1 As shown, it includes a mounting frame 1, with a fixed head 3 fixedly connected to the bottom of the mounting frame 1. A movable head 5 is rotatably connected inside the fixed head 3, and a data acquisition and analysis device 2 is fixedly connected to the bottom of the movable head 5. It also includes an adjustment mechanism, which is set on the movable head 5. The adjustment mechanism includes a protruding rod 14 and a plurality of second inner grooves 13 arranged around the movable head 5. When the movable head 5 moves inside the fixed head 3, the protruding rod 14 reinforces the angle of the movable head 5.

[0026] The adjustment mechanism includes a fixed rod 9, with a pressing rod 10 fixedly connected to the top of the fixed rod 9. The fixed rod 9 and a fixed tube 8 fixedly connected to the bottom of the movable head 5 are threaded together. The movable head 5 has a hollow groove 11 communicating with the fixed tube 8, and multiple first inner grooves 12 communicating with the hollow grooves 11. Each end of the first inner groove 12 has a second inner groove 13. Two protruding rods 14 are installed in each pair of second inner grooves 13, and a spring 15 is provided between the two protruding rods 14. The spring 15 is located in the first inner groove 12. Since the fixed rod (9) is threadedly connected to the fixed tube (8), the rotation of the fixed rod (9) will cause it to move in the vertical direction. The pressing rod (10) at the top of the fixed rod (9) moves accordingly. As the pressing rod (10) moves, its pressing action on the protruding rod (14) changes. Under the elastic force of the spring (15), the protruding rod (14) moves. Slide along the second inner groove (13) and gradually insert into or disengage from the recess (16) on the inner wall of the movable groove (4) inside the fixed head (3). When the protruding rod (14) is inserted into the recess (16), the current angle of the movable head (5) is reinforced and locked. When the angle needs to be adjusted, continue to rotate the fixed rod (9) so that the squeezing rod (10) squeezes the protruding rod (14), overcomes the elastic force of the spring (15), and allows the protruding rod (14) to disengage from the recess (16). At this time, the movable head (5) can be rotated to adjust the acquisition and analysis device (2) to a suitable angle. Through the cooperation of the protruding rod, spring, squeezing rod and fixed rod, the precise adjustment and reinforcement locking of the movable head angle are achieved, overcoming the problems of easy wear and slippage of the universal adjustment structure in the prior art and inaccurate capture offset caused by structural slippage during the acquisition process, thereby ensuring the stability and reliability of data acquisition.

[0027] The fixed head 3 has a movable groove 4 inside, and the inner wall of the movable groove 4 has multiple notches 16. The outer end of the protruding rod 14 has an arc-shaped structure that matches the notches 16.

[0028] The diameter of the extrusion rod 10 gradually widens from the top to the bottom, and the top edge of the extrusion rod 10 has an arc-shaped structure. By setting the diameters of the top and bottom of the extrusion rod 10 to be different, it is convenient for the extrusion rod 10 to be inserted into the hollow groove 11, and it is also convenient for the extrusion rod 10 to control the ejection distance of the protrusion rod 14.

[0029] The bottom end of the fixed rod 9 is fixedly connected to the first fixed clamp 6, and the bottom end of the first fixed clamp 6 is slidably connected to the second fixed clamp 7. The data acquisition and analysis device 2 is slidably connected to the bottom end of the second fixed clamp 7.

[0030] The sliding direction of the data acquisition and analysis device 2 within the second fixed clamp 7 is different from the sliding direction of the second fixed clamp 7 within the first fixed clamp 6.

[0031] Working principle: When the angle of the acquisition and analysis device (2) needs to be adjusted, rotate the fixed rod (9). Since the fixed rod (9) is threadedly connected to the fixed tube (8), the rotation of the fixed rod (9) will cause it to move in the vertical direction. The pressing rod (10) at the top of the fixed rod (9) will move accordingly. As the pressing rod (10) moves, its pressing action on the protruding rod (14) changes. Under the elastic force of the spring (15), the protruding rod (14) slides along the second inner groove (13) and gradually inserts into or separates from the recess (16) on the inner wall of the movable groove (4) inside the fixed head (3). When the protruding rod (14) is inserted into the recess (16), the current angle of the movable head (5) is reinforced and locked. When the angle needs to be adjusted, continue to rotate the fixed rod (9) so that the pressing rod (10) presses the protruding rod (14) to overcome the elastic force of the spring (15) and let the protruding rod (14) separate from the recess (16). At this time, the movable head (5) can be rotated to adjust the acquisition and analysis device (2) to a suitable angle.

[0032] The data acquisition and analysis device (2) is slidably connected to the bottom of the first fixed clamp (6) through the second fixed clamp (7), and it can also slide within the second fixed clamp (7), with different sliding directions. This allows the data acquisition and analysis device (2) to be flexibly adjusted in space, so as to accurately collect multi-dimensional data on the dancer's movements according to different street dance competition venue layouts, dancer positions, etc., such as movement amplitude, speed, acceleration, rhythm matching degree, space occupation range, etc. After the data is collected, it is analyzed and processed, and transformed into intuitive evaluation parameters to assist judges in making more scientific, comprehensive and objective evaluation decisions.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
