Description

Technical Field

[0001] This invention belongs to the field of physical fitness testing technology, specifically an intelligent sit-up tester. Background Technology

[0002] The sit-up tester is a specialized sports testing device, mainly used to automatically and objectively measure the number of sit-ups that a subject can complete within a specified time while maintaining standard movements, in order to assess the strength and endurance of their abdominal muscle groups.

[0003] Patent CN219423683U discloses an integrated intelligent sit-up testing device, featuring a movable mat, a foot hook column, a foot hook crossbar, a display device, a high-position probe, and a low-position probe. The device further includes at least two flexible tension components connected to the ends of the foot hook crossbar. Each flexible tension component comprises a connecting part, a wireless tension sensor, a tension band, and a pull ring connected in sequence. The wireless tension sensor communicates with the display device to transmit the subject's tension data for display. Simultaneously, the high-position and low-position probes transmit sit-up data to the display device via infrared transmission and reception, enabling display. This patent not only satisfies sit-up testing but also tests and exercises the upper arms and upper back, improving its practical effectiveness.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: By setting up high and low probes, the low probe is covered when the test subject is in a supine position, and the high probe is covered when the test subject is in a sitting position. A count is completed after both probes have been covered once. However, a standard sit-up requires the test subject's shoulder blades to be in contact with the mat. During the test, the test subject may not have proper posture, resulting in the shoulder blades not being in contact with the mat. If the shoulder blades are not touching the mat, it means the test subject has not completed a full range of motion (from fully supine to fully seated). The test subject can repeatedly trigger the high and low probes by performing small "crunches" or rapid "nodding," thus obtaining a large number of invalid counts with non-standard, effortless, and shortened movements, which cannot accurately reflect the subject's physical fitness level. Summary of the Invention

A limiting rod one is rotatably provided at one end of the pressure rod two. One end of the limiting rod one is inserted into and slidably connected to the limiting rod two.

[0007] Preferably, one side of the telescopic rod is threadedly connected to a threaded rod four, one end of which is rotatably disposed at one end of the inner cavity of the sleeve, and one side of the inner cavity of the sleeve is fixedly connected to a motor five, the output end of which is fixedly connected to one end of the threaded rod four.

[0008] Preferably, a bidirectional threaded rod is rotatably provided at both ends of the inner side of the adjustment groove, and the two sides of the bidirectional threaded rod are respectively threadedly connected to the adjustment blocks on both sides. A motor six is ​​fixedly connected to one side of the test plate, and the output end of the motor six is ​​fixedly connected to one end of the bidirectional threaded rod.

[0009] Preferably, an eccentric block is rotatably provided on one side of the adjusting block, the eccentric block is in contact with the bottom side of the tactile block, a telescopic rod three is fixedly connected to the lower side of the tactile block, a sleeve two is slidably connected to the telescopic rod three, the lower end of the sleeve two is fixedly connected to the adjusting block, and a spring two is sleeved on the sleeve two, one end of the spring two is fixedly connected to the tactile block, and the other end is fixedly connected to the adjusting block.

[0010] Preferably, a motor seven is fixedly connected to one side of the adjusting block, and the output end of the motor seven is fixedly connected to one end of the eccentric block.

[0011] Preferably, a threaded rod is threadedly connected to one side of the bottom of the adjustment plate, and both ends of the threaded rod are rotatably mounted on the test plate. A motor is fixedly connected to one side of the test plate, and the output end of the motor is fixedly connected to one end of the threaded rod.

[0012] Preferably, a threaded rod three is threadedly connected to one side of the telescopic rod two, one end of the threaded rod three is rotatably disposed on one side of the inner cavity of the sleeve three, and a motor four is fixedly connected to one side of the inner cavity of the sleeve three, with the output end of the motor four being fixedly connected to one end of the threaded rod three.

[0016] The beneficial effects of this invention are as follows: 1. The intelligent sit-up tester of this invention utilizes an adaptive motion correction component, ensuring that the test subject can only count the sit-up from a fully supine position. This avoids the test subject repeatedly triggering infrared sensor one and infrared sensor two through small-amplitude "crunches" or rapid "nodding," thus obtaining a large number of invalid counts with non-standard, effortless, and shortened movements, further guaranteeing the accuracy of the test results. Furthermore, when the test subject's body unintentionally shifts position, or when the movement is too fast, resulting in the body only contacting one pressure sensor or not contacting it at all, the tactile block provides a tactile prompt to the test subject's back, reminding them to adjust to the standard posture in time. This avoids situations where the test subject's body unintentionally shifts position or moves too fast, resulting in the body only contacting one pressure sensor or not contacting it at all, leading to multiple uncounted movements and affecting the accuracy of the test results. This is a more intelligent design.

[0017] 2. The intelligent sit-up tester of the present invention utilizes an adjustable foot limiting component, which, with the coordinated action of limiting rod one, limiting rod two, pressure rod two, pressure rod one, telescopic rod two, and sleeve three, limits the tester's feet. The tester's feet can hook onto pressure rod one as the point of force application, without causing lateral slippage of the feet due to the application of force, thus ensuring the stability of the test.

[0021] The technical solution of the present invention will now be clearly and completely described 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.

[0022] Please refer to Figures 1-8 The present invention provides a technical solution: an intelligent sit-up tester, including a test plate 1, an infrared sensor 5 fixedly connected to one side of the test plate 1, a slider 17 slidably connected to one side of the test plate 1, a sleeve 7 fixedly connected to one side of the upper end face of the slider 17, a telescopic rod 6 slidably connected to the inner cavity of the sleeve 7, an infrared sensor 4 fixedly connected to the upper end of the telescopic rod 6, a display screen 9 fixedly connected to one side of the upper end face of the test plate 1, and an adaptive motion correction component is also provided on the test plate 1; The adaptive motion correction component includes an adjustment groove 8 set on one side of the test plate 1. Adjustment blocks 27 are slidably connected to both sides inside the adjustment groove 8. A tactile block 28 is slidably connected to one side of the upper end of the adjustment block 27. A pressure sensor 35 is set on the upper end of the tactile block 28. The test board 1 is also equipped with an adjustable foot limit component; The adjustable foot limiting assembly includes an adjusting plate 10 slidably connected to one side of the test plate 1. A sleeve 34 is fixedly connected to the middle of the upper surface of the adjusting plate 10. A telescopic rod 11 is slidably connected to the inner cavity of the sleeve 34. A pressure rod 2 is fixedly connected to the upper end of the telescopic rod 11. Pressure rods 12 are slidably connected to both sides of the inner cavity of the pressure rod 12. A limiting rod 14 is rotatably provided at one end of the pressure rod 12. A limiting rod 15 is inserted into and slidably connected to one end of the limiting rod 14.

[0023] In this embodiment, as Figure 3 , Figure 4 , Figure 8 As shown, a threaded rod 24 is threadedly connected to one side of the telescopic rod 6. One end of the threaded rod 24 is rotatably set at one end of the inner cavity of the sleeve 7. A motor 23 is fixedly connected to one side of the inner cavity of the sleeve 7. The output end of the motor 23 is fixedly connected to one end of the threaded rod 24.

[0024] The inner ends of the adjustment groove 8 are rotatably provided with bidirectional threaded rods 26. The two sides of the bidirectional threaded rods 26 are respectively threaded to the adjustment blocks 27 on both sides. The test plate 1 is fixedly connected to one side of the motor 6 25. The output end of the motor 6 25 is fixedly connected to one end of the bidirectional threaded rods 26.

[0025] An eccentric block 30 is rotatably mounted on one side of the adjusting block 27. The eccentric block 30 is in contact with the bottom side of the tactile block 28. A telescopic rod 33 is fixedly connected to the lower side of the tactile block 28. A sleeve 31 is slidably connected to the telescopic rod 33. The lower end of the sleeve 31 is fixedly connected to the adjusting block 27. A spring 32 is mounted on the sleeve 31. One end of the spring 32 is fixedly connected to the tactile block 28, and the other end is fixedly connected to the adjusting block 27.

[0026] A motor 29 is fixedly connected to one side of the adjusting block 27, and the output end of the motor 29 is fixedly connected to one end of the eccentric block 30.

[0027] Specifically, existing sit-up testing devices use high and low probes. When the test subject is lying down, the low probe is covered; when sitting, the high probe is covered. A count is completed after both probes have been covered once. However, a standard sit-up requires the test subject's shoulder blades to be in contact with the mat. During the test, the test subject may not maintain proper posture, resulting in the shoulder blades not touching the mat. If the shoulder blades are not touching the mat, it means the test subject has not completed a full range of motion from lying flat to sitting up. Test subjects can repeatedly trigger the high and low probes by performing small "crunches" or rapid "nodding," thus obtaining a large number of invalid counts with non-standard, effortless, and shortened movements, failing to accurately reflect the subject's physical fitness level.

[0028] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, the test subject lies on the test plate 1. Based on the test subject's body width, motor 6 25 drives the bidirectional threaded rod 26 to rotate, causing the adjusting blocks 27 on both sides to slide simultaneously. This adjusts the distance between the two pressure sensors 35, ensuring that when the test subject lies flat, both pressure sensors 35 are in contact with the test subject's shoulder blades. Meanwhile, the infrared sensor 2 5 is positioned at the test subject's neck. Then, based on the test subject's upper body length, the slider 17 slides on the test plate 1. Simultaneously, motor 5 23 drives the threaded rod 4 24 to rotate, causing the telescopic rod 1 6 to slide within the sleeve 1 7, adjusting the height of the infrared sensor 1 4 so that when the test subject is seated, the infrared sensor 1 4 can detect the test subject's head.

[0029] After completing the above adjustments, the tester can begin the test. During the test, when the tester is in a standard supine position, both pressure sensors 35 detect pressure signals simultaneously, and the infrared sensor 2 5 is covered. When the tester is in a standard sitting position, the pressure sensors 35 no longer detect signals, and the infrared sensor 2 5 is not covered. At this time, only the infrared sensor 1 4 is covered, thus achieving one count, and the number is displayed on the display screen 9. This ensures that the tester can only count from a completely supine position to a completely seated position, preventing the tester from repeatedly triggering the infrared sensor 1 4 and the infrared sensor 2 5 through small "abdominal crunches" or rapid "head nods," thereby obtaining a large number of invalid counts with non-standard, effortless, and shortened stroke movements, further ensuring the accuracy of the test results.

[0030] However, in some cases, during the test, the test subject's body may unintentionally shift, or the movement may be too fast, resulting in the test subject's body only contacting one pressure sensor 35 or not contacting the pressure sensor 35 at all, without the test subject being aware of this. This can lead to multiple movements of the test subject not being counted, which will also affect the accuracy of the test results. Therefore, to avoid this problem, whenever infrared sensor 4 and infrared sensor 5 are alternately covered, and only one pressure sensor 35 detects a pressure signal, or neither pressure sensor 35 detects a pressure signal, it indicates that the test subject's body has shifted, or the movement is too fast, causing the two shoulder blades to not be in contact with the test plate 1. At this time, motor 7 29 will drive eccentric block 30 to rotate. The proximal and distal ends of eccentric block 30 will alternately contact the bottom of tactile block 28. When the distal end of eccentric block 30 contacts the bottom of tactile block 28, tactile block 28 will rise. When the proximal end of eccentric block 30 contacts the bottom of tactile block 28, tactile block 28 will return to its original position under the action of sleeve 2 31, spring 2 32, and telescopic rod 3 33. This causes tactile block 28 to move up and down repeatedly and actively contact the back of the tester, providing tactile feedback to remind the tester that the movement is not standardized and needs to be adjusted in time. At the same time, because the tester's back receives tactile feedback, it helps the tester to quickly adjust to the standard posture. This avoids the situation where the tester's body accidentally shifts or moves too quickly, causing the tester's body to only contact one pressure sensor 35 or not contact the pressure sensor 35 at all, resulting in multiple movements of the tester not being counted, thus affecting the accuracy of the test results. This is more intelligent.

[0031] In this embodiment, as Figure 2 , Figure 5 , Figure 6 As shown, a threaded rod 3 is threadedly connected to one side of the bottom of the adjustment plate 10. Both ends of the threaded rod 3 are rotatably mounted on the test plate 1. A motor 16 is fixedly connected to one side of the test plate 1. The output end of the motor 16 is fixedly connected to one end of the threaded rod 3.

[0032] One side of the telescopic rod 21 is threadedly connected to a threaded rod 32. One end of the threaded rod 32 is rotatably mounted on one side of the inner cavity of the sleeve 34. One side of the inner cavity of the sleeve 34 is fixedly connected to a motor 41. The output end of the motor 41 is fixedly connected to one end of the threaded rod 32.

[0033] A motor 18 is fixedly connected to one side of the inner cavity of the pressure rod 12. Threaded rods 19 are fixedly connected to the output ends of the motor 18 on both sides, and the threaded rods 19 on both sides are threadedly connected to the pressure rods 12 on both sides.

[0034] One end of the pressure rod 12 is fixedly connected to the motor 13, and the output end of the motor 13 is fixedly connected to one end of the limit rod 14.

[0035] One end of the limiting rod 14 is fixedly connected to a spring 20, and the other end of the spring 20 is fixedly connected to one end of the inner cavity of the limiting rod 15.

[0036] Specifically, in existing sit-up testing devices, the test taker's feet hook onto the horizontal bar, providing a fulcrum for exertion and helping to engage the core muscles. However, because the distance between the horizontal bar and the pad is fixed, there is a possibility that the distance may be too small, preventing the test taker's feet from passing between the bar and the pad. Furthermore, during the test, the test taker's feet are prone to lateral slippage due to the exertion of force, causing them to detach from the horizontal bar and thus affecting the proper conduct of the test.

[0037] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, based on the size of the tester's foot, motor 421 drives threaded rod 32 to rotate, causing telescopic rod 21 to slide within the inner cavity of sleeve 34. This adjusts the distance between pressure rod 12 and test plate 1, allowing the tester's foot to pass smoothly between pressure rod 12 and test plate 1. During adjustment, limiting rod 14 and limiting rod 25 will slide relative to each other, and limiting rod 25 will remain in contact with test plate 1 under the action of spring 120. Then, based on the width of the tester's foot, motor 318 drives threaded rod 22... 9. Rotate to allow pressure rod 2 12 to slide within the cavity of pressure rod 1 2. Adjust the gap between limiting rod 1 14 and telescopic rod 2 11, and make limiting rod 1 14 and limiting rod 2 15 fit against the tester's feet. With the coordinated action of limiting rod 1 14, limiting rod 2 15, pressure rod 2 12, pressure rod 1 2, telescopic rod 2 11, and sleeve 3 34, the tester's feet are limited. The tester's feet can hook onto pressure rod 1 2 as a point of force application, without causing lateral slippage of the feet due to force application, thus ensuring the stability of the test.

[0038] Working principle: First, the test subject lies on the test plate 1. Based on the test subject's body width, motor 6 25 drives the bidirectional threaded rod 26 to rotate, causing the adjusting blocks 27 on both sides to slide simultaneously. This adjusts the distance between the two pressure sensors 35, ensuring that when the test subject is lying flat, both pressure sensors 35 are in contact with the test subject's shoulder blades. Simultaneously, the infrared sensor 2 5 is aligned with the test subject's neck. Then, based on the test subject's upper body length, the slider 17 slides on the test plate 1. At the same time, motor 5 23 drives the threaded rod 4 24 to rotate, causing the telescopic rod 1 6 to slide within the sleeve 1 7, adjusting the height of the infrared sensor 1 4 so that when the test subject is in a seated position, the infrared sensor 1 4 can detect the test subject's head.

[0039] After completing the above adjustments, the tester can begin the test. During the test, when the tester is in a standard supine position, both pressure sensors 35 detect pressure signals simultaneously, and the infrared sensor 2 5 is covered. When the tester is in a standard sitting position, the pressure sensors 35 no longer detect signals, and the infrared sensor 2 5 is not covered. At this time, only the infrared sensor 1 4 is covered, thus achieving one count, and the number is displayed on the display screen 9. This ensures that the tester can only count from a completely supine position to a completely seated position, preventing the tester from repeatedly triggering the infrared sensor 1 4 and the infrared sensor 2 5 through small "abdominal crunches" or rapid "head nods," thereby obtaining a large number of invalid counts with non-standard, effortless, and shortened stroke movements, further ensuring the accuracy of the test results.

[0040] However, in some cases, during the test, the test subject's body may unintentionally shift, or the movement may be too fast, resulting in the test subject's body only contacting one pressure sensor 35 or not contacting the pressure sensor 35 at all, without the test subject being aware of this. This can lead to multiple movements of the test subject not being counted, which will also affect the accuracy of the test results. Therefore, to avoid this problem, whenever infrared sensor 4 and infrared sensor 5 are alternately covered, and only one pressure sensor 35 detects a pressure signal, or neither pressure sensor 35 detects a pressure signal, it indicates that the test subject's body has shifted, or the movement is too fast, causing the two shoulder blades to not be in contact with the test plate 1. At this time, motor 7 29 will drive eccentric block 30 to rotate. The proximal and distal ends of eccentric block 30 will alternately contact the bottom of tactile block 28. When the distal end of eccentric block 30 contacts the bottom of tactile block 28, tactile block 28 will rise. When the proximal end of eccentric block 30 contacts the bottom of tactile block 28, tactile block 28 will return to its original position under the action of sleeve 2 31, spring 2 32, and telescopic rod 3 33. This causes tactile block 28 to move up and down repeatedly and actively contact the back of the tester, providing tactile feedback to remind the tester that the movement is not standardized and needs to be adjusted in time. At the same time, because the tester's back receives tactile feedback, it helps the tester to quickly adjust to the standard posture. This avoids the situation where the tester's body accidentally shifts or moves too quickly, causing the tester's body to only contact one pressure sensor 35 or not contact the pressure sensor 35 at all, resulting in multiple movements of the tester not being counted, thus affecting the accuracy of the test results. This is more intelligent.

[0041] Based on the tester's foot size, motor 421 drives threaded rod 322 to rotate, causing telescopic rod 21 to slide within sleeve 34. This adjusts the distance between pressure rod 12 and test plate 1, allowing the tester's foot to pass smoothly between pressure rod 12 and test plate 1. During adjustment, limiting rod 14 and limiting rod 25 will slide relative to each other, and limiting rod 25 will remain in contact with test plate 1 under the action of spring 120. Subsequently, based on the width of the tester's foot, motor 318 drives threaded rod 219 to rotate. The movement causes the pressure rod 12 to slide within the inner cavity of the pressure rod 2, adjusting the gap between the limiting rod 14 and the telescopic rod 11, and ensuring that the limiting rod 14, the limiting rod 15, and the tester's feet are in contact. With the coordinated action of the limiting rod 14, the limiting rod 15, the pressure rod 12, the pressure rod 2, the telescopic rod 11, and the sleeve 34, the tester's feet are restricted. The tester's feet can hook onto the pressure rod 2 as a point of force application, without causing lateral slippage of the feet due to the force applied, thus ensuring the stability of the test.
