Technical Field

[0001] This invention relates to the field of sports testing technology, specifically a comprehensive testing instrument for vocational school physical education teaching. Background Technology

[0002] The comprehensive testing instrument for physical education in vocational schools is a specialized testing device designed for physical education teaching, student physical health testing, and physical fitness training assessment in vocational schools. It can automatically test indicators such as height and weight, and can replace traditional manual measurement methods. It can achieve accurate collection, rapid recording, and standardized statistics of physical test data, effectively simplify the physical education teaching testing process, and improve teaching management efficiency. It is an important teaching equipment that is suitable for the large student population in vocational schools and meets the needs of daily teaching and physical fitness assessment.

[0003] When using comprehensive testing equipment for physical education in vocational schools, the testing method usually adopts a horizontal physical barrier combined with a height support. Different levels of high jump are tested by adjusting the height of the barrier. During the test, the score is determined by the limb touching the barrier. This method has problems such as the barrier being easy to fall off, the need for manual reset after touching, and the cumbersome height adjustment operation. It is not easy to adapt to the use scenario of continuous testing of a large number of students in vocational schools, and it is difficult to meet the long-term stable use needs of physical education in vocational schools.

[0004] To address the above issues, a comprehensive testing instrument for vocational school physical education teaching is proposed. Summary of the Invention

A rotating shaft is rotatably connected to the bottom of the adjustment frame.

[0009] Furthermore, the height compensation component includes an inclined block fixedly connected to the bottom of the threaded plate, a rotating shaft rollingly connected to the inclined block, and several movable shafts rotatably connected to the bottom of the inclined block, all of which are rollingly connected to the top of the lifting rod.

[0010] Furthermore, the test assembly includes a conical protective cylinder fixedly connected to one side of the adjustment frame, an elastic plate fixedly connected inside the conical protective cylinder, four support columns fixedly connected inside the conical protective cylinder, a limit sleeve fixedly connected inside the four support columns, a first connecting ball rolledly connected inside the limit sleeve, a nine-axis attitude sensor installed inside the first connecting ball, a through-beam laser sensor installed on the outer wall of the first connecting ball, and a photoelectric sensor installed on the inner wall of one end of the through-beam laser sensor.

[0011] Furthermore, the angle compensation component includes a first rotating shaft fixedly connected to the other output end of the first dual-axis motor. The first rotating shaft is rotatably connected to the adjustment frame. A rotating frame is fixedly connected to one end of the first rotating shaft. A slider is slidably connected inside the rotating frame. A second connecting ball is slidably connected inside the slider. A first connecting post is fixedly connected to the outer wall of the second connecting ball. A second connecting post is slidably connected to the outer wall of the first connecting post. The other end of the second connecting post is fixedly connected to the outer wall of the first connecting ball.

[0012] Furthermore, the adjustment assembly includes a mounting frame fixedly connected to the top of the slider, a second dual-axis motor is installed inside the mounting frame, a second threaded rod is fixedly connected to one of the output ends of the second dual-axis motor, the second threaded rod is rotatably connected to the mounting frame, and the second threaded rod is threadedly connected to the rotating frame.

[0013] Furthermore, the pushing component includes a second rotating shaft fixedly connected to the output of the other end of the second dual-axis motor, a rotating plate fixedly connected to one end of the second rotating shaft, and an inclined plate fixedly connected to one end of the rotating plate.

[0014] Furthermore, the optical attenuation compensation component includes a sliding sleeve slidably connected inside the first connecting ball, an elastic plate fixedly connected to the outer wall of the sliding sleeve, a lens fixedly connected to one end of the sliding sleeve, a plurality of slots evenly opened on the outer wall of the sliding sleeve, an L-shaped support rod fixedly connected to the bottom of one end of the sliding sleeve, a rotating wheel rotatably connected inside the L-shaped support rod, and the rotating wheel rollingly connected to the inclined plate.

[0015] Furthermore, the locking assembly includes two second springs that are fixedly connected to the first connecting ball. One end of each second spring is fixedly connected to a locking rod, which is slidably connected to the first connecting ball and engages with a locking groove.

Through the cooperation between the nine-axis attitude sensor and the angle compensation component, the spatial attitude tilt of the test component can be detected in real time and the tilt angle can be dynamically corrected. This accurately achieves coaxial alignment of the optical path of the laser emission and receiving structure, avoiding detection failure or misjudgment due to equipment tilt and ensuring test reliability. By combining photoelectric sensors and optical decay compensation components, the optical decay status of the laser emitter can be monitored in real time, and the light intensity can be dynamically compensated by a focusing lens to restore the emission intensity and sensitivity of the detection optical path, solve the problem of laser aging and decay, and extend the overall service life of the equipment. By cooperating with the locking component and the light attenuation compensation component, a stable snap-fit ​​positioning can be achieved after the light attenuation compensation component completes the stepped displacement, avoiding displacement of the compensation structure, ensuring the accuracy of light intensity compensation, and allowing the equipment to maintain stable detection effect even after long-term use. By setting up the weighing scale and the overall control structure, weight data can be collected and a high jump detection function can be integrated to form a comprehensive testing device for vocational school physical education teaching. This enables automated testing without touching the bar or requiring manual reset, improving the convenience and efficiency of physical education teaching testing. Attached Figure Description

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical issues that arise when using comprehensive testing equipment for vocational school physical education, such as the easy fall of the stop bar, the need for manual reset after being touched, and the cumbersome height adjustment operation, making it unsuitable for the continuous testing scenarios of large numbers of students in vocational schools, such as... Figures 1-8 and Figures 10-12 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 2As shown, a comprehensive testing instrument for vocational school physical education includes a U-shaped support frame 1, which can support and fix various components. A controller is installed on one side of the U-shaped support frame 1, which can control various electrical components. The controller is existing technology and is not shown in the figure. A weight scale 2 is installed on one side of the U-shaped support frame 1, which can collect the weight data of the tester and transmit it to the controller. In conjunction with the subsequent high jump detection structure, a comprehensive test for physical education is realized. Two lifting components 3 are arranged opposite each other on the U-shaped support frame 1. A drive component 4 is set on the top of each of the two lifting components 3. A laser sensor 11 is set on the top of each of the two drive components 4.

[0021] like Figure 5 As shown, each of the two drive components 4 has a height compensation component 5 at one of its output ends. The height compensation component 5 can perform height compensation based on the detection data of the laser sensor 11. Each of the two drive components 4 has a test component 6 on one side. The detection end of the laser sensor 11 is installed vertically upward and corresponds to the position of the inner wall of the U-shaped support frame 1. It can detect the distance between itself and the U-shaped support frame 1, and then provide feedback on the real-time lifting height of the two test components 6 to verify the height synchronization status and check for lifting deviations. The two lifting components 3 can synchronously drive the two test components 6 and the laser sensor 11 to lift and lower, thereby adjusting the detection height of the jump. The two test components 6 are a laser emitting structure and a laser receiving structure, respectively, which can be mutually emitted to form a jump detection optical path.

[0022] When in use, place the U-shaped support frame 1 in a suitable indoor location. At this time, the controller enables the two lifting components 3 to drive the two sets of drive components 4 and test components 6 to lift synchronously. The laser sensor 11 detects the height of the two sets of drive components 4 and test components 6 in real time until the appropriate height is reached. The lifting height data of the two drive components 4 and test components 6 can be compared in real time.

[0023] Scenario 1: If used for a long time, due to mechanical wear and increased transmission clearance of the lifting component 3, the drive component 4 and the test component 6 may exceed or fall below the required height. In this case, the controller, in conjunction with the detection data of the laser sensor 11, causes the corresponding drive component 4 to drive the height compensation component 5 to move, which in turn causes the test component 6 to rise or fall accordingly. This corrects the height deviation of the two lifting components 3 in real time, ensuring that the laser emitting and receiving components are always at the same horizontal height and maintaining stable alignment of the beam path. Subsequently, the controller causes the laser emitting structure of one test component 6 to stably emit a detection laser, while the laser receiving structure of the other test component 6 continuously receives the laser signal and forms a closed detection beam path, thereby testing the jump performance of the tester. This enables automated jump detection without a physical crossbar, avoiding problems such as collisions, misjudgments, and manual resets. Compared with the defects of existing technologies such as easily damaged physical crossbars and cumbersome height adjustment, this method can significantly improve the accuracy, stability, and efficiency of jump testing.

[0024] Test component 6 is equipped with a photoelectric sensor 7, which can monitor the luminous intensity of the laser emitter in real time and identify the light decay state, such as... Figure 7 As shown, a nine-axis attitude sensor 8 is installed inside the test component 6. The nine-axis attitude sensor 8 can detect the spatial attitude of the test component 6 in real time and determine whether tilting has occurred. Figure 6 As shown, each of the two drive components 4 has an angle compensation component 9 at its other output end. The angle compensation component 9 is fixedly connected to the test component 6. The angle compensation component 9 can drive the test component 6 to rotate according to the detection data, correcting the attitude tilt, such as... Figure 8 As shown, the angle compensation component 9 is equipped with an adjustment component 10, and a pushing component 20 is provided on one side of the adjustment component 10. The light decay compensation component 30 is slidably arranged in the test component 6. The light decay compensation component 30 can compensate for the attenuation of the laser by adjusting its position and restore the detected light intensity. Two locking components 40 are arranged opposite each other in the test component 6. Both locking components 40 are engaged with the light decay compensation component 30. During the initial calibration, the laser sensor 11 detects the reference distance between itself and the inner wall of the U-shaped support frame 1, records the zero points of the height on both sides and completes the height reference calibration. The photoelectric sensor 7 collects the initial light intensity of the laser emitting end, sets the light decay judgment threshold and completes the light intensity reference calibration. The nine-axis attitude sensor 8 collects the initial spatial attitude of the test component 6, determines the horizontal reference and angle deviation threshold and completes the attitude zero point calibration.

[0025] Scenario 2: If used for a long time, due to the deformation of the U-shaped support frame 1 and the vibration of the test component 6 caused by external forces, the test component 6 may tilt. At the same time, the nine-axis attitude sensor 8 detects the spatial attitude deviation of the test component 6, and the detected value exceeds the set threshold. At this time, the controller causes one of the output ends of the adjustment component 10 to rotate, thereby driving the angle compensation component 9 to move and simultaneously driving the test component 6 to adjust to a suitable angle. This allows for preliminary correction of the tilt state of the test component 6 based on the angle deviation data, and prepares for the subsequent coaxial alignment of the laser emitting and receiving structure optical paths. Subsequently, the controller causes the other output end of the drive component 4 to drive the angle compensation component 9 to rotate in a circle until the detected value of the nine-axis attitude sensor 8 returns to the set threshold. This achieves dynamic angle compensation of the test component 6, which can accurately correct the spatial tilt angle of the test component 6, ensuring that the detected values ​​of the laser emitting and receiving structure optical paths return to the normal test range and avoiding detection failure or misjudgment due to tilt.

[0026] Scenario 3: If used for a long time, the laser emission structure of test component 6 will experience attenuation of luminous intensity and reduction of optical power. At the same time, the photoelectric sensor 7 will detect that the luminous intensity of the emitting end is lower than the set threshold, indicating an abnormal light decay. In this case, the controller will reset the drive component 4, the angle compensation component 9, and the test component 6, so that the value of the nine-axis attitude sensor 8 will be restored to the value before the angle compensation of test component 6. At this time, the position of the push component 20 will correspond to the position of the light decay compensation component 30. Then, the controller will rotate the other output end of the adjustment component 10 and drive the push component 20 to rotate synchronously. This will cause the push component 20 to push the light decay compensation component 30 to perform axial stepped sliding displacement on the test component 6. The light decay compensation component 30 can focus the light to dynamically compensate for the attenuated laser, thereby restoring the emission intensity and detection sensitivity of the detection optical path.

[0027] After the light intensity compensation is completed, the operation steps of Case 2 are repeated through the controller to restore the detection value of the nine-axis attitude sensor 8 to the set threshold. If the detection data of the laser sensor 11, the nine-axis attitude sensor 8 and the photoelectric sensor 7 exceed the compensation range, an alarm will be triggered to remind the user to perform maintenance. The alarm is existing technology and is not shown in the figure.

[0028] like Figures 2-6 As shown, the lifting assembly 3 includes a support rod 31 fixedly connected to the U-shaped support frame 1, an electric push rod 32 installed inside the support rod 31, a lifting rod 33 fixedly connected to the movable end of the electric push rod 32, a limit rod 34 fixedly connected inside the U-shaped support frame 1, and the lifting rod 33 and the limit rod 34 slidably connected.

[0029] like Figures 4-8 and Figure 12As shown, the drive assembly 4 includes four guide rods 42 slidably connected to the top of the lifting rod 33. Each of the four guide rods 42 has a first spring 41 fixedly connected to its bottom, and the other end of the first spring 41 is fixedly connected to the inner wall of the lifting rod 33. An adjustment frame 43 is fixedly connected to the top of the four guide rods 42. A laser sensor 11 is installed on the top of the adjustment frame 43. A first dual-axis motor 44 is installed inside the adjustment frame 43. One output shaft of the first dual-axis motor 44 is fixedly connected to a first threaded rod 45. The first threaded rod 45 is rotatably connected to the adjustment frame 43. A threaded plate 47 is threadedly connected to the outer wall of the first threaded rod 45. Several sliding rods 46 are fixedly connected inside the adjustment frame 43. The threaded plate 47 is slidably connected to the several sliding rods 46. A rotating shaft 48 is rotatably connected to the bottom of the adjustment frame 43.

[0030] like Figure 6 As shown, the height compensation component 5 includes an inclined block 51 fixedly connected to the bottom of the threaded plate 47, a rotating shaft 48 rollingly connected to the inclined block 51, and several movable shafts 52 rotatably connected to the bottom of the inclined block 51. The several movable shafts 52 are all rollingly connected to the top of the lifting rod 33.

[0031] like Figures 4-8 , Figure 10 and Figure 11 As shown, the test assembly 6 includes a conical protective cylinder 61 fixedly connected to one side of the adjustment frame 43. An elastic plate 62 is fixedly connected inside the conical protective cylinder 61, which can provide protection. Four support columns 63 are fixedly connected inside the conical protective cylinder 61. A limit sleeve 64 is fixedly connected inside the four support columns 63. A first connecting ball 65 is rolled inside the limit sleeve 64. A nine-axis attitude sensor 8 is installed inside the first connecting ball 65. A through-beam laser sensor 66 is installed on the outer wall of the first connecting ball 65. A photoelectric sensor 7 is installed on the inner wall of one end of the through-beam laser sensor 66. There are two through-beam laser sensors 66, which are installed in two conical protective cylinders 61 respectively. One is the laser emitting end and the other is the laser receiving end. At the same time, the photoelectric sensor 7 is installed inside the laser emitting end.

[0032] When in use, place the U-shaped support frame 1 in a suitable indoor location. At this time, the controller will cause the two electric push rods 32 to drive the lifting rods 33 to rise and fall under the limit of the limit rods 34, and drive the two sets of adjustment frames 43 and the through-beam laser sensor 66 to rise and fall synchronously. The laser sensor 11 will detect the height of the two sets of adjustment frames 43 and the through-beam laser sensor 66 in real time until the appropriate height is reached. The lifting height data of the two sets of adjustment frames 43 and the through-beam laser sensor 66 can be compared in real time.

[0033] Scenario 1: If, after prolonged use, the electric push rod 32 experiences mechanical wear and increased transmission clearance, and the detection data from the laser sensor 11 is outside the normal range, causing the adjusting frame 43 and the through-beam laser sensor 66 to fall below the required height, the controller, in conjunction with the detection data from the laser sensor 11, will cause the corresponding first dual-axis motor 44 to drive the first threaded rod 45 to rotate. This causes the threaded plate 47, limited by the slide rod 46, to move the inclined block 51, causing the moving shaft 52 to roll at the top of the lifting rod 33. The inclined block 51 then presses against the rotating shaft 48, pushing the adjusting frame 43 to cause the four guide rods 42 to slide within the lifting rod 33, and stretching the first spring 41, thus adjusting the... The segment 43 drives the corresponding rise of the through-beam laser sensor 66, thereby correcting the height deviation of the two lifting bars 33 in real time. This ensures that the laser emitting and receiving components are always at the same horizontal height, maintaining stable alignment of the through-beam optical path. Subsequently, through the controller, the laser emitting end of the through-beam laser sensor 66 stably emits detection laser, and the laser receiving end continuously receives the laser signal and forms a closed detection optical path, thereby testing the jump performance of the tester. This enables automated jump detection without physical crossbars, avoiding problems such as bar collisions, misjudgments, and manual resets. Compared with the shortcomings of existing technologies such as easily damaged physical crossbars and cumbersome height adjustment, this technology can significantly improve the accuracy, stability, and efficiency of jump testing.

[0034] To address the technical problem of the through-beam laser sensor 66 tilting after prolonged use, which affects testing, such as... Figures 6-12 As shown, the following preferred technical solutions are provided: like Figure 7 , Figure 8 and Figure 12 As shown, the angle compensation component 9 includes a first rotating shaft 91 fixedly connected to the other output end of the first dual-axis motor 44. The first rotating shaft 91 is rotatably connected to the adjustment frame 43. One end of the first rotating shaft 91 is fixedly connected to a rotating frame 92. A slider 93 is slidably connected inside the rotating frame 92. A second connecting ball 94 is rollably connected inside the slider 93. A first connecting post 95 is fixedly connected to the outer wall of the second connecting ball 94. A second connecting post 96 is slidably connected to the outer wall of the first connecting post 95. The other end of the second connecting post 96 is fixedly connected to the outer wall of the first connecting ball 95.

[0035] like Figure 12As shown, the adjustment assembly 10 includes a mounting frame 101 fixedly connected to the top of the slider 93. A second dual-axis motor 102 is installed inside the mounting frame 101. Both the first dual-axis motor 44 and the second dual-axis motor 102 are dual-output shaft drive motors, capable of independently controlling the two output shafts. Both the first dual-axis motor 44 and the second dual-axis motor 102 have a self-locking function. A second threaded rod 103 is fixedly connected to one of the output ends of the second dual-axis motor 102. The second threaded rod 103 is rotatably connected to the mounting frame 101 and threadedly connected to the rotating frame 92.

[0036] like Figure 9 and Figure 12 As shown, the pushing component 20 includes a second rotating shaft 201 fixedly connected to the output of the other end of the second dual-axis motor 102. A rotating plate 202 is fixedly connected to one end of the second rotating shaft 201, and an inclined plate 203 is fixedly connected to one end of the rotating plate 202.

[0037] like Figures 7-11 As shown, the optical attenuation compensation component 30 includes a sliding sleeve 301 slidably connected to the first connecting ball 65, an elastic plate 62 fixedly connected to the outer wall of the sliding sleeve 301, a lens 302 fixedly connected to one end of the sliding sleeve 301, the lens 302 being a convex focusing lens 302, which can focus and enhance the laser light, compensate for the optical attenuation at the emitting end, and improve the intensity of the detection optical path. Several slots 303 are evenly opened on the outer wall of the sliding sleeve 301, and an L-shaped support rod 304 is fixedly connected to the bottom of one end of the sliding sleeve 301. A rotating wheel 305 is rotatably connected inside the L-shaped support rod 304, and the rotating wheel 305 is rollingly connected to the inclined plate 203.

[0038] like Figure 10 As shown, the locking assembly 40 includes two second springs 401 that are fixedly connected to the first connecting ball 65. One end of each second spring 401 is fixedly connected to a locking rod 402. The locking rod 402 is slidably connected to the first connecting ball 65. One end of the locking rod 402 is arc-shaped and can smoothly engage with the slot 303 to achieve stepped positioning. The locking rod 402 engages with the slot 303.

[0039] Scenario 2: With prolonged use, due to the deformation of the U-shaped support frame 1 and the vibration of the laser emitter and receiver of the through-beam laser sensor 66 caused by external forces, the through-beam laser sensor 66 may tilt. Simultaneously, the nine-axis attitude sensor 8 detects a spatial attitude deviation of the through-beam laser sensor 66, exceeding a set threshold. At this point, the controller activates the second dual-axis motor 102, which drives the second threaded rod 103 to rotate. Through the threaded connection between the second threaded rod 103 and the rotating frame 92, the mounting frame 101 causes the slider 93 to slide within the rotating frame 92. The second connecting ball 94 rolls within the slider 93, causing the first connecting post 95 to slide within the second connecting post 96. This simultaneously adjusts the first connecting ball 65 and the through-beam laser sensor 66 to a suitable angle, allowing adjustment based on angle deviations. The data is used to initially correct the tilt of the through-beam laser sensor 66, and prepare for the subsequent coaxial alignment of the laser emitting and receiving structures. Then, the controller drives the first dual-axis motor 44 to rotate the first rotating shaft 91 and the rotating frame 92. The rotating frame 92 drives the slider 93, the second connecting ball 94, the first connecting post 95 and the second connecting post 96 to rotate in a circle. This causes the first connecting ball 65 to rotate in a circle within the limiting sleeve 64 until the detection value of the nine-axis attitude sensor 8 returns to the set threshold. This achieves dynamic angle compensation of the through-beam laser sensor 66, which can accurately correct the spatial tilt angle of the through-beam laser sensor 66, ensuring that the detection values ​​of the laser emitting end and the laser receiving end return to the normal test range, and avoiding detection failure or misjudgment due to tilt.

[0040] Scenario 3: If used for an extended period, the laser emission end of the through-beam laser sensor 66 experiences attenuation of luminous intensity and reduction of optical power. Simultaneously, the photoelectric sensor 7 detects that the luminous intensity of the emission end is below a set threshold, indicating an abnormal light decay. In this case, the controller resets the first dual-axis motor 44, the first rotating shaft 91, the rotating frame 92, the first connecting ball 65, and the through-beam laser sensor 66, restoring the value of the nine-axis attitude sensor 8 to the value before angle compensation of the through-beam laser sensor 66. At this point, the position of the inclined plate 203 corresponds to the horizontal position of the rotating wheel 305. Subsequently, the controller drives the second dual-axis motor 102 to... The second rotating shaft 201, rotating plate 202, and inclined plate 203 rotate, and the inclined plate 203 pushes the rotating wheel 305, causing the sliding sleeve 301 to slide axially in a stepped manner within the first connecting ball 65. At the same time, it overcomes the elastic force of the second spring 401, causing the locking rod 402 to disengage from the locking slot 303 until the locking rod 402 engages with the new locking slot 303, thus achieving automatic locking. This adjusts the distance between the lens 302 and the laser emitting end of the through-beam laser sensor 66, enabling dynamic light intensity compensation for the attenuated laser by focusing the light through the lens 302, thereby restoring the emission intensity of the laser emitting end of the through-beam laser sensor 66.
