Description

[0002] Human maneuverability testing is a key technical means to assess human maneuverability. It is widely used in many fields such as rehabilitation medicine, sports science, and human-computer interaction.

[0022] See also Figure 1-5 As shown, an embodiment of this application provides a multifunctional operating force testing bracket, comprising: The upper limb force measuring component 1 includes an upper limb force measuring base plate 11, an upper limb force measuring platform 12, an upper limb angle adjusting component 13, and an upper limb fixing bracket 14. The upper limb force measuring platform 12 is connected to the upper limb force measuring base plate 11. The upper limb angle adjusting component 13 is disposed between the upper limb force measuring platform 12 and the upper limb force measuring base plate 11 and is used to adjust the tilt angle of the upper limb force measuring platform 12 relative to the upper limb force measuring base plate 11. The upper limb fixing bracket 14 is disposed on the upper limb force measuring platform 12. The lower limb force measuring component 2 includes a lower limb force measuring base plate 21, a lower limb force measuring platform 22, a lower limb height adjusting component 23, and a lower limb fixation bracket 24. The upper limb force measuring base plate 11 is detachably connected to the lower limb force measuring base plate 21. The lower limb force measuring platform 22 is connected to the lower limb force measuring base plate 21. The lower limb height adjusting component 23 is disposed between the lower limb force measuring platform 22 and the lower limb force measuring base plate 21 to adjust the height of the lower limb force measuring platform 22 relative to the lower limb force measuring base plate 21. The lower limb fixation bracket 24 is disposed on the lower limb force measuring platform 22.

[0023] In this technical solution, the multifunctional operational force testing bracket provided in this application embodiment includes an upper limb force measuring component 1 and a lower limb force measuring component 2. The upper limb force measuring component 1 includes an upper limb force measuring base plate 11, an upper limb force measuring platform 12, an upper limb angle adjustment component 13, and an upper limb fixation bracket 14. The lower limb force measuring component 2 includes a lower limb force measuring base plate 21, a lower limb force measuring platform 22, a lower limb height adjustment component 23, and a lower limb fixation bracket 24. The upper limb force measuring base plate 11 and the lower limb force measuring base plate 21 are detachably connected. The upper limb angle adjustment component 13 is used to adjust the tilt angle of the upper limb force measuring platform 12 relative to the upper limb force measuring base plate 11. The lower limb height adjustment component 23 is used to adjust the height of the lower limb force measuring platform 22 relative to the lower limb force measuring base plate 21. The upper limb fixation bracket 14 and the lower limb fixation bracket 24 can be equipped with various sensors to realize the detection and collection of the operational force of the test subject.

[0024] Based on this, when conducting human maneuvering force tests, the tilt angle of the upper limb force measuring platform 12 relative to the upper limb force measuring base plate 11 can be adjusted using the upper limb angle adjustment component 13 to accommodate different upper limb testing postures such as standing, sitting, and supine positions. The height of the lower limb force measuring platform 22 relative to the lower limb force measuring base plate 21 can be adjusted using the lower limb height adjustment component 23 to meet the lower limb testing needs of subjects of different heights. Simultaneously, by installing corresponding push-pull force, rotational force, and other sensors using the upper limb fixation bracket 14 and lower limb fixation bracket 24, various types of maneuvering force tests, such as upper limb push-pull force, double-arm rotational force, single-arm rotational force, and lower limb stepping force, can be conducted. During this process, the detachable installation of the upper limb force measuring base plate 11 and the lower limb force measuring base plate 21 allows the device to be used in combination or separately depending on the testing scenario. When combined as a whole, it can conduct upper and lower limb coordinated maneuvering force tests; when used separately, it can complete upper or lower limb tests independently, greatly improving the adaptability and flexibility of the testing bracket.

[0025] Understandably, the upper limb angle adjustment component 13 can adjust the tilt angle of the upper limb force measuring platform 12 relative to the upper limb force measuring base plate 11, meet the upper limb operational force testing needs under different body positions, and improve the comprehensiveness of the test; the lower limb height adjustment component 23 can adjust the height of the lower limb force measuring platform 22, adapt to the testing needs of testers of different heights, and improve the convenience of the test.

[0026] Understandably, the upper limb fixation bracket 14 and the lower limb fixation bracket 24 provide a stable mounting platform for various sensors. Testers can install the corresponding sensors on the upper limb fixation bracket 14 or the lower limb fixation bracket 24 according to the test requirements for subsequent testing.

[0027] In one feasible embodiment, the upper limb angle adjustment member 13 includes: Support plate 131, the first end of which is connected to the first end of the upper limb force measuring platform 12, and the second end of which is rotatably connected to the upper limb force measuring base plate 11; Drive plate 132, which is slidably disposed on the upper limb force measuring base plate 11; A connecting rod 133 is disposed between the drive plate 132 and the second end of the upper limb force measuring platform 12; The first driving component 134 is connected to the driving plate 132 and is used to drive the driving plate 132 to move on the upper limb force measuring base plate 11.

[0028] In this technical solution, the upper limb angle adjustment component 13 includes a support plate 131, a drive plate 132, a connecting rod 133, and a first drive component 134. The first end of the support plate 131 is connected to the upper limb force measuring platform 12, and the second end is rotatably connected to the upper limb force measuring base plate 11, forming a rotation point for angle adjustment. The drive plate 132 is slidably mounted on the upper limb force measuring base plate 11. The connecting rod 133 is rotatably connected between the drive plate 132 and the second end of the upper limb force measuring platform 12. The first drive component 134 is connected to the drive plate 132 and can drive the drive plate 132 to move on the upper limb force measuring base plate 11. The connecting rod 133 drives the second end of the upper limb force measuring platform 12 to move, so that the upper limb force measuring platform 12 can rotate around the rotation point of the support plate 131, thereby realizing the adjustment of the tilt angle of the upper limb force measuring platform 12 to adapt to the upper limb testing postures of the test personnel in different positions such as standing, sitting, and supine.

[0029] Based on this, when it is necessary to adjust the tilt angle of the upper limb force measuring platform 12 according to the test requirements, the first drive component 134 is activated. The first drive component 134 will drive the drive plate 132 to slide on the upper limb force measuring base plate 11. During the movement of the drive plate 132, the power is transmitted to the upper limb force measuring platform 12 through the connecting rod 133, so that the upper limb force measuring platform 12 rotates around the rotation point between itself and the upper limb force measuring base plate 11, thereby realizing the adjustment of the tilt angle of the upper limb force measuring platform 12 relative to the upper limb force measuring base plate 11. It can adapt to the upper limb operational force test requirements of different body positions such as the push test when the subject is standing, the push-pull test when sitting, and the pull test when lying supine.

[0030] Understandably, the first drive component 134 can be a drive component with a self-locking function, such as an electric push rod or a lead screw motor. After adjustment, it can firmly lock the position of the drive plate 132 to prevent the upper limb force measuring platform 12 from shifting at an angle during the test, thus ensuring the stability and safety of the test.

[0031] In one feasible embodiment, the first drive element 134 includes: The first fixing plate 1341 is symmetrically arranged on the upper limb force measuring base plate 11; The first drive seat 1342 is disposed on the drive plate 132; The first drive rod 1343 is disposed between the first fixed plates 1341 and threadedly connected to the first drive seat 1342. When the first drive rod 1343 is rotated, it can drive the drive plate 132 to move on the upper limb force measuring base plate 11.

[0032] In this technical solution, the first driving component 134 includes a first fixing plate 1341, a first driving seat 1342, and a first driving rod 1343. The first fixing plate 1341 is symmetrically assembled on the upper limb force measuring base plate 11 to support and position the first driving rod 1343. The first driving seat 1342 is fixedly disposed on the driving plate 132 and forms a threaded connection with the first driving rod 1343. The first driving rod 1343 is installed between the two first fixing plates 1341 and is threadedly connected to the first driving seat 1342.

[0033] Based on this, when it is necessary to adjust the tilt angle of the upper limb force measuring platform 12, the first drive rod 1343 can be rotated. The first drive rod 1343 is threadedly connected to the first drive seat 1342. When the two ends of the drive plate 132 are limited, the rotational motion of the first drive rod 1343 will be converted into the linear motion of the first drive seat 1342, thereby driving the drive plate 132 to slide along the upper limb force measuring base plate 11. The sliding of the drive plate 132 will cause the upper limb force measuring platform 12 to rotate around the rotation point between it and the upper limb force measuring base plate 11 through the connecting rod 133, thereby realizing the adjustment of the tilt angle of the upper limb force measuring platform 12 and meeting the needs of upper limb operation force testing under different body positions.

[0034] It is understandable that the first drive rod 1343 is threadedly connected to the first drive seat 1342. After adjustment, the position of the drive plate 132 can be fixed without additional locking parts, preventing the upper limb force measuring platform 12 from shifting its angle due to force during the test and ensuring the stability of the test data. At the same time, the adjustment method is manual, which can be used in various scenarios such as laboratory and outdoor testing. It is convenient to operate and has low maintenance cost.

[0035] Understandably, a handwheel is installed on one end of the first drive rod 1343 to facilitate its rotation.

[0036] In one feasible embodiment, the system further includes an upper limb support fixing seat 15, which is slidably disposed on the upper limb force measuring platform 12 and can move along a first direction. The upper limb fixing bracket 14 is disposed on the upper limb support fixing seat 15 and can slide along a second direction. The first direction is perpendicular to the second direction.

[0037] The technical solution also includes an upper limb support fixation seat 15, which is used to fix the upper limb fixation bracket 14. During use, the tester can adjust the position of the upper limb support fixation seat 15 according to the tester's height, test position and specific test requirements. First, move the fixation seat along the first direction to adjust its front-to-back distance with the subject's upper limb; then slide the upper limb fixation bracket 14 along the second direction perpendicular to the first direction to adjust its left-to-right position. Finally, align the upper limb fixation bracket 14 and the sensor mounted on it with the subject's upper limb operating area to adapt to the test requirements of subjects with different body types.

[0038] It is understood that the first direction is the axial direction of the upper limb force measuring platform 12, and the second direction is the direction perpendicular to the axial direction of the upper limb force measuring platform 12.

[0039] In one feasible embodiment, the upper limb support fixation base 15 includes: An upper limb fixation plate 151 is slidably disposed on the upper limb force measuring platform 12. A second drive rod 152 is disposed on the upper limb force measuring platform 12. The second drive rod 152 is threadedly connected to the upper limb fixation plate 151. Rotating the second drive rod 152 can drive the upper limb fixation plate 151 to slide along a first direction on the upper limb force measuring platform 12. The third drive rod 153 is slidably disposed on the upper limb fixation plate 151. The upper limb fixation bracket 14 is slidably disposed on the upper limb fixation plate 151 and threadedly connected to the upper limb fixation bracket 14. Rotating the third drive rod 153 can drive the upper limb fixation bracket 14 to move along the second direction on the upper limb fixation plate 151.

[0040] In this technical solution, the upper limb support fixing base 15 includes an upper limb fixing plate 151, a second drive rod 152, and a third drive rod 153. The upper limb fixing plate 151 is slidably mounted on the upper limb force measuring platform 12. The second drive rod 152 is mounted on the lower limb force measuring platform 22 and threadedly connected to the upper limb fixing plate 151. Rotating the second drive rod 152 can drive the upper limb fixing plate 151 to slide along a first direction. The upper limb fixing bracket 14 is slidably mounted on the upper limb fixing plate 151. The third drive rod 153 is mounted on the upper limb fixing plate 151 and threadedly connected to the upper limb fixing bracket 14. Rotating the third drive rod 153 can drive the upper limb fixing bracket 14 to move along a second direction perpendicular to the first direction, thereby enabling the adjustment of the position of the upper limb fixing bracket according to the needs of the test subject.

[0041] Based on this, when preparing for upper limb manipulation force testing, the tester can adjust the position of the upper limb fixation bracket 14 according to the subject's height, arm length, test position, and specific test requirements. First, rotate the second drive rod 152 to slide the upper limb fixation plate 151 along the first direction, adjusting the front-to-back distance between the upper limb fixation bracket 14 and the subject's upper limb. Then, rotate the third drive rod 153 to slide the upper limb fixation bracket 14 along the second direction, adjusting the left-to-right position of the upper limb fixation bracket 14 so that the sensor mounted on the upper limb fixation bracket 14 is aligned with the subject's upper limb manipulation area, ensuring the consistency of the relative position between the sensor and the upper limb manipulation area, and meeting the usage needs of different subjects.

[0042] In one feasible embodiment, the lower limb height adjustment member 23 includes: Substrate 231, which is slidably disposed on the lower limb force measuring base plate 21; The first slider 232 is symmetrically disposed on the first end of the substrate 231 and is slidably connected to the substrate 231; The second slider 233 is symmetrically arranged at the bottom of the first end of the lower limb force measuring platform 22 and is slidably connected to the lower limb force measuring platform 22; A first support rod 234, the first end of the first support rod 234 is rotatably connected to the first slider 232, and the second end of the first support rod 234 is rotatably connected to the second end of the lower limb force measuring platform 22; The second support rod 235 has a first end rotatably connected to the second slider 233, and a second end rotatably connected to the lower limb force measuring base plate 21. The first support rod 234 is rotatably connected to the middle part of the second support rod 235. The second driving member 236 is disposed between the base plate 231 and the lower limb force measuring platform 22.

[0043] In this technical solution, the lower limb height adjustment component 23 includes a base plate 231, a first slider 232, a second slider 233, a first support rod 234, a second support rod 235, and a second driving component 236. The base plate 231 is slidably mounted on the lower limb force measuring base plate 21. There are two first sliders 232, which are symmetrically arranged at the first end of the base plate 231 and slidably connected to the base plate 231. There are two second sliders 233, which are symmetrically mounted at the bottom of the first end of the lower limb force measuring platform 22 and slidably connected to the lower limb force measuring platform 22. The two ends of the first support rod 234 are rotatably connected to the first slider 232 and the second end of the lower limb force measuring platform 22, respectively. The two second support rods 235 are rotatably connected to the second slider 233 and the lower limb force measuring base plate 21, respectively, and the two are rotatably connected at the middle to form a scissor lift structure. The second driving component 236 is installed between the base plate 231 and the lower limb force measuring platform 22, and the second driving component 236 provides power for the height adjustment of the lower limb force measuring platform 22. When the height of the lower limb force measuring platform 22 needs to be adjusted according to the height of the subject or the testing requirements, the lower limb force measuring platform 22 is moved up and down relative to the base plate 231 by the second drive component 236, which will drive the first slider 232 and the second slider 233 to slide. Then, through the scissor-type lifting structure formed by the first support rod 234 and the second support rod 235, the distance between the lower limb force measuring platform 22 and the base plate 231 can be adjusted to meet the testing height requirements of different subjects.

[0044] In one feasible embodiment, the second drive element 236 includes: The first fixing seat 2361 is disposed on the base plate 231; The first adjusting plate 2362 is symmetrically arranged in the first fixed base 2361, and the first end of the first adjusting plate 2362 is rotatably connected to the first fixed base 2361. The second fixing seat 2363 is disposed on the lower limb force measuring platform 22; The second adjusting plate 2364 is symmetrically arranged inside the second fixed base 2363, and the first end of the second adjusting plate 2364 is rotatably connected to the second fixed base 2363. A connecting shaft is disposed between the second end of the first adjusting plate 2362 and the second end of the second adjusting plate 2364; The fourth drive rod 2365 is threadedly connected to the connecting shaft. Rotating the fourth drive rod 2365 can drive the second end of the first adjusting plate 2362 and the second end of the second adjusting plate 2364 to move towards or in opposite directions.

[0045] In this technical solution, the second driving component 236 includes a first fixed base 2361, a first adjusting plate 2362, a second fixed base 2363, a second adjusting plate 2364, a connecting shaft, and a fourth driving rod 2365. The first fixed base 2361 is fixedly mounted on the base plate 231. Two first adjusting plates 2362 are symmetrically arranged inside the first fixed base 2361, with their first ends rotatably connected to the first fixed base 2361. The second fixed base 2363 is correspondingly installed at the bottom of the lower limb force measuring platform 22. The second adjusting plate 2364... There are two measuring plates, symmetrically arranged inside the second fixed base 2363, and their first ends are rotatably connected to the second fixed base 2363; the connecting shaft is installed between the second end of the first adjusting plate 2362 and the second end of the second adjusting plate 2364, and the fourth driving rod 2365 is threadedly connected to the connecting shaft. When the fourth driving rod 2365 is manually rotated, it can drive the second ends of the first adjusting plate 2362 and the second adjusting plate 2364 to move towards or away from each other, thereby adjusting the height of the lower limb force measuring platform 22 relative to the base plate 231 to meet different usage requirements.

[0046] Based on this, when the height of the lower limb force measuring platform 22 needs to be adjusted, the tester rotates the fourth drive rod 2365, which is threadedly connected to the connecting shaft, thereby causing the second end of the first adjusting plate 2362 and the second end of the second adjusting plate 2364 to move towards or away from each other. Since the first adjusting plate 2362 is rotatably connected to the first fixed seat 2361 and the first end of the second adjusting plate 2364 is rotatably connected to the second fixed seat 2363, when the second end of the first adjusting plate 2362 and the second end of the second adjusting plate 2364 move towards or away from each other, the height of the lower limb force measuring platform 22 will change relative to the base plate 231, so that the height of the lower limb force measuring platform 22 can be adapted to the lower limb testing needs of subjects of different heights, and can also match the lower limb operational force testing posture requirements in different body positions such as standing and sitting.

[0047] In one feasible embodiment, a fifth drive rod 25 is also included. The fifth drive rod 25 is disposed on the lower limb force measuring base plate 21. The fifth drive rod 25 is threadedly connected to the base plate 231. Rotating the fifth drive rod 25 can drive the base plate 231 to move on the lower limb force measuring base plate 21.

[0048] The technical solution also includes a fifth drive rod 25, which is mounted on the lower limb force measuring base plate 21 and threadedly connected to the base plate 231. Therefore, when the fifth drive rod 25 is rotated, the two sides of the base plate 231 are slidably connected to the lower limb force measuring base plate 21, which can limit the base plate 231. Rotating the fifth drive rod 25 can drive the base plate 231 to slide on the lower limb force measuring base plate 21, thereby moving the position of the lower limb force measuring platform 22 and meeting the needs of different test subjects.

[0049] In one feasible embodiment, the system further includes a lower limb support fixing seat 26, which is slidably disposed on the lower limb force measuring platform 22 and can slide along a first direction. The lower limb fixing bracket 24 is disposed on the lower limb support fixing seat 26 and can slide along a second direction. The first direction and the second direction are perpendicular to each other.

[0050] This technical solution also includes a lower limb support fixture 26, which is slidably mounted on a lower limb force measuring platform 22 and can move smoothly along a first direction. A lower limb fixation bracket 24 is slidably mounted on the lower limb support fixture 26 and can slide along a second direction perpendicular to the first direction. This allows the position of the lower limb fixation bracket 24 on the lower limb force measuring platform 22 to be adjusted according to the subject's needs. Before conducting lower limb operational force testing, the tester can adjust the positions of the lower limb support fixture 26 and the lower limb fixation bracket 24 according to the subject's needs: first, move the lower limb support fixture 26 along the first direction, then slide the lower limb fixation bracket 24 along the second direction perpendicular to the first direction, adjusting its left and right positions to ensure that the foot sensor mounted on the fixation bracket maintains the optimal relative position with the lower limb operating part of the human body.

[0051] It is understood that the first direction is the axial direction of the lower limb force measuring platform 22, and the second direction is the direction perpendicular to the axial direction of the lower limb force measuring platform 22.

[0052] In one feasible embodiment, the lower limb support fixation base 26 includes: A lower limb fixation plate 261 is slidably disposed on the lower limb force measuring platform 22. A sixth drive rod 262 is disposed on the lower limb force measuring platform 22. The sixth drive rod 262 is threadedly connected to the lower limb fixation plate 261. Rotating the sixth drive rod 262 can drive the lower limb fixation plate 261 to slide along a first direction on the lower limb force measuring platform 22. The seventh drive rod 263 is slidably mounted on the lower limb fixation plate 261. The seventh drive rod 263 is mounted on the lower limb fixation plate 261 and threadedly connected to the lower limb fixation bracket 24. Rotating the seventh drive rod 263 can drive the lower limb fixation bracket 24 to move along the second direction on the lower limb fixation plate 261.

[0053] In this technical solution, the lower limb support fixing base 26 includes a lower limb fixing plate 261, a sixth drive rod 262, and a seventh drive rod 263. The lower limb fixing plate 261 is slidably mounted on the lower limb force measuring platform 22. The sixth drive rod 262 is mounted on the lower limb force measuring platform 22 and threadedly connected to the lower limb fixing plate 261. Rotating the sixth drive rod 262 drives the lower limb fixing plate 261 to slide along a first direction. The lower limb fixing bracket 24 is slidably disposed on the lower limb fixing plate 261. The seventh drive rod 263 is mounted on the lower limb fixing plate 261 and threadedly connected to the lower limb fixing bracket 24. Rotating the seventh drive rod 263 drives the lower limb fixing bracket 24 to move along a second direction perpendicular to the first direction, thereby adjusting the position of the lower limb fixing bracket 24. According to usage requirements, the sensors mounted on the lower limb fixing bracket 24 are aligned with the placement position of the subject's feet, ensuring consistency between the sensors and the lower limb operating parts, improving the adaptability of the testing posture, and ensuring the accuracy of the test data.
