Description

Technical Field

[0001] This invention relates to the field of automotive crash test measurement technology, specifically providing an auxiliary assembly device for measuring automotive crash dummies. Background Technology

[0002] Car crash dummies are high-end testing equipment for evaluating vehicle safety and are an important technical measure of vehicle safety performance. Using crash dummies to conduct crash tests instead of real people can simulate human injury under different conditions. Therefore, crash dummies need to have a high degree of biomechanical fidelity. Only by achieving a high degree of biomechanical fidelity can the center of mass, mass, and moment of inertia obtained from static measurements of crash dummies be similar to or even the same as those of a real human body.

[0003] Current static measurements of automotive crash dummies involve mounting the dummy on a measurement test bench and then performing multi-point support calculations on the dummy within the fixture. This method is not complex for small parts (such as the head). However, for parts with large mass and volume, such as the torso, positioning, assembly, and measurement steps are required. This often necessitates the cooperation of 3 to 4 people to complete the entire process, making the assembly of the torso with the measurement test bench extremely cumbersome, wasting significant manpower and resources, and greatly reducing the efficiency of dummy assembly and measurement.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of low assembly efficiency of the torso and measurement test platform of existing automobile collision dummies.

[0006] In a first aspect, the present invention provides an auxiliary assembly device for measuring a car crash test dummy. The auxiliary assembly device is capable of transferring the dummy's torso to a measurement test bench and assembling it onto the test bench. The auxiliary assembly device includes: a movable base, a lifting mechanism, an angle calibration mechanism, a support mechanism, and an assembly mechanism. The bottom of the movable base is provided with a set of wheels with a self-locking function. The lifting mechanism is mounted on the movable base. The angle calibration mechanism is mounted on the top of the lifting mechanism, and the lifting mechanism is capable of moving the angle calibration mechanism vertically up and down. The support mechanism is detachably fixedly mounted on the angle calibration mechanism, and the torso is detachably fixedly mounted on the support mechanism. The assembly mechanism is disposed on the support mechanism and is used to tighten fasteners connecting the torso to the measurement test bench.The angle calibration mechanism includes a support member, a fixed disk, a rotating disk, locking pins, a first drive member, and a transmission gear set. The bottom end of the support member is fixedly connected to the top end of the lifting mechanism. There are two support members spaced apart along a first horizontal direction. There are two fixed disks, vertically arranged, each mounted on the inner sidewall of one of the two support members. There are two rotating disks, vertically arranged, rotatably mounted on the two fixed disks. The rotation axis of each rotating disk extends along the first horizontal direction. The fixed disk is located between the support member and the rotating disk, coaxially arranged with the fixed disk. The fixed disk has multiple first locking holes evenly distributed circumferentially. The rotating disk has multiple second locking holes evenly distributed circumferentially. Multiple locking pins are present, capable of penetrating the first and second locking holes to restrict the rotation of the rotating disk relative to the fixed disk. A first connecting structure is provided at the center of the rotating disk. Four second connecting structures are provided on the supporting mechanism. Two of the four second connecting structures are spaced apart along the first horizontal direction, and the other two are spaced apart along a second horizontal direction, which is perpendicular to the first horizontal direction. When X-axis measurement is required, the two second connecting structures along the first horizontal direction can be detachably and fixedly connected to the first connecting structures on the two rotating disks respectively. When Y-axis measurement is required, the two second connecting structures along the second horizontal direction can be detachably and fixedly connected to the first connecting structures on the two rotating disks respectively. A first driving component is mounted on one of the supporting components and is driven by one of the rotating disks through the transmission gear set to drive the rotating disk to rotate, thereby rotating the supporting mechanism and the torso mounted on the supporting mechanism, and thus calibrating the angle of the torso.

[0007] By adopting the above technical solution, this invention, through a movable base and lifting mechanism, allows the torso to be moved horizontally and vertically, thereby initially positioning the torso's fixed point with the fixed point of the measuring experimental platform. Then, the angle calibration mechanism rotates the torso to align it with the fixed point on the platform. Finally, the assembly mechanism tightens the fasteners to securely connect the torso to the measuring experimental platform. This allows the torso's transportation, assembly, and measurement work to be completed by a single person, greatly improving the assembly efficiency and measurement efficiency of the torso, and saving manpower. Furthermore, by detachably mounting the torso onto the support mechanism, and then detachably mounting the support mechanism onto the angle calibration mechanism, installation and disassembly efficiency are improved. By connecting the rotating disk with... The fixed disk is rotatably connected, and a first connecting structure is set on the rotating disk. Two opposing second connecting structures on the bearing mechanism are connected to two first connecting structures, which makes the bearing mechanism more stable and less prone to shaking during rotation. By setting four second connecting structures on the bearing mechanism and disassembling two opposing second connecting structures from two first connecting structures and replacing them with two other opposing second connecting structures connected to two first connecting structures, the torso can be measured along the X and Y axes, thereby improving measurement efficiency. The rotating disk is driven to rotate by the transmission gear set driven by the first driving component. The structure is simple and easy to operate. The rotating disk is locked by inserting a locking pin into the first locking hole and the second locking hole, which can lock the torso in a certain position, thereby making the assembly of the torso more precise.

[0008] In the preferred embodiment of the above-mentioned auxiliary assembly device, the assembly mechanism includes a slide rod, a slider, an adjusting rod, and an assembler. The slider is mounted on the slide rod and can slide relative to the slide rod along its length. The assembler is mounted on the top of the adjusting rod and can rotate relative to the adjusting rod. The assembler is used to tighten the fasteners connecting the torso and the measuring experimental platform. The bottom end of the adjusting rod is pivotally connected to the slider to adjust the angle of the assembler. The bearing mechanism is provided with two sliding grooves extending along the first horizontal direction and arranged opposite to each other along the second horizontal direction. The slide rod extends along the second horizontal direction, and its two ends are respectively inserted into the two sliding grooves. The slide rod can slide along the length of the sliding groove to adjust the distance between the assembler and the torso.

[0009] By adopting the above technical solution, the present invention allows the adjusting rod and the assembler to move freely in the horizontal direction by sliding the sliding rod along the sliding groove and the slider along the sliding rod. By pivotally connecting the bottom end of the adjusting rod to the slider, the assembler at the top of the adjusting rod can also rotate, thereby allowing the assembler to move and extend into the torso, and fix the torso to the measuring experimental table, thus improving the assembly efficiency of the torso.

[0010] In the preferred embodiment of the above-mentioned auxiliary assembly device, the top end of the adjusting rod is provided with a through hole, and the assembler is rotatably installed in the through hole. The first end and the second end of the assembler are respectively provided with a first connector and a second connector. The first connector and the second connector are respectively located on both sides of the through hole. The first connector can be used to install a tool for tightening fasteners, and the second connector can be used to install a wrench. By rotating the wrench, the assembler and the tool are rotated to tighten the fasteners.

[0011] By adopting the above technical solution, the present invention improves the assembly efficiency of the torso by rotatably installing the assembler in the through hole at the top of the adjusting rod and providing a first connector and a second connector at the first and second ends of the assembler, respectively, so that the two ends of the assembler can be connected to an installation wrench and an Allen wrench, respectively.

[0012] In the preferred embodiment of the above-mentioned auxiliary assembly device, the bearing mechanism includes a bearing member and mounting columns disposed on the bearing member. The bearing member is horizontally arranged, and the second connecting structure and the slide are both disposed on the bearing member. The mounting columns are vertically arranged and located on one side of the slide along its length. There are two mounting columns, which are spaced apart along the second horizontal direction. Each mounting column includes a first vertical plate and a second vertical plate spaced apart along the first horizontal direction, and a first horizontal plate and a second horizontal plate spaced up and down along the vertical direction. The first vertical plate is disposed close to the slide, and the height of the first vertical plate is greater than the height of the second vertical plate. One end of the first horizontal plate is fixedly connected to or integrally disposed with the top end of the first vertical plate. The two ends of the second horizontal plate are respectively fixed to the top ends of the first vertical plate and the second vertical plate. The torso is either connected or integrated. The first and second horizontal plates are respectively provided with a first mounting hole and a second mounting hole coaxially arranged in the vertical direction. A connecting ear is provided on each of the left and right sides of the torso. Each connecting ear includes a first ear plate and a second ear plate spaced vertically apart. The first and second ear plates are respectively provided with a first connecting hole and a second connecting hole coaxially arranged in the vertical direction. When the torso is installed onto the mounting post, the second ear plate is located between the first and second horizontal plates, and its upper and lower surfaces are respectively in contact with the first and second horizontal plates. The first horizontal plate is located between the first and second ear plates, and its upper and lower surfaces are respectively in contact with the first and second ear plates. The first connecting hole and the second connecting hole are aligned with the first mounting hole and the second mounting hole.

[0013] When the above technical solution is adopted, the present invention provides a mounting column on the load-bearing member, and provides a first horizontal plate and a second horizontal plate that are spaced apart vertically on the mounting column. This ensures that when the torso is installed on the mounting column, the first ear plate and the second ear plate on the torso fit together with the first horizontal plate and the second horizontal plate from top to bottom in the order of first ear plate, first horizontal plate, second ear plate, and second horizontal plate. The first connecting hole and the second connecting hole are aligned with the first mounting hole and the second mounting hole, thereby enhancing the connection strength between the torso and the mounting column.

[0014] In the preferred embodiment of the above-mentioned auxiliary assembly device, the assembler is configured to be able to extend and retract along its length.

[0015] By adopting the above technical solution, the present invention makes the assembler more flexible and versatile in use and improves assembly efficiency by setting the assembler to be able to extend and retract along its length.

[0016] In the preferred embodiment of the above-mentioned auxiliary assembly device, the top surface of the slide rod is provided with a protruding rib extending along the second horizontal direction. The cross-section of the protruding rib is semi-circular. The bottom of the slider is provided with a semi-circular groove. The groove is adapted to the protruding rib and can slide along the length direction of the protruding rib. The slide rod is also provided with two limiting grooves extending along the second horizontal direction. The number of limiting grooves is two and they are respectively located on both sides of the protruding rib along the first horizontal direction. Each end of the slider along the first horizontal direction is provided with a limiting rib. The two limiting ribs are respectively inserted into the two limiting grooves to prevent the slider from separating from the protruding rib. The limiting ribs can move along the length direction of the limiting groove.

[0017] By adopting the above technical solution, the present invention can prevent the slider from separating from the rib by setting a limiting groove on the slide bar and setting a limiting rib on the slider, and the structure is simple.

[0018] In the preferred embodiment of the above-mentioned auxiliary assembly device, the first connecting structure is a connecting column extending along the first horizontal direction. A slot is provided at the end of the connecting column away from the rotating disk. A first through hole is provided in the connecting column in a vertical direction at a position corresponding to the slot. The top and bottom of the connecting column are set as horizontal planes at positions corresponding to the first through hole. The second connecting structure is a horizontally arranged connecting plate. A second through hole is provided on the connecting plate. The connecting plate is inserted into the slot, and the first through hole is aligned with the second through hole.

[0019] With the above technical solution adopted, the present invention has a simple structure and is easy to install and disassemble by inserting the connecting plate into the slot of the connecting column.

[0020] In the preferred embodiment of the above-mentioned auxiliary assembly device, the first driving component is a driving handle. The driving handle includes a handle portion, a connecting portion, and a driving portion connected in sequence. The handle portion and the driving portion both extend along the first horizontal direction, and the connecting portion extends along the second horizontal direction. The driving portion is rotatably mounted on the support component. The handle portion and the connecting portion are located on the outside of the support component. The driving end of the driving portion passes through the support component and extends into the inside of the support component. The transmission gear set includes a first tooth structure, an intermediate gear, and a second tooth structure that are meshed in sequence. The first tooth structure is disposed at the driving end of the driving portion, and the second tooth structure is disposed on the rotating disk. The intermediate gear is rotatably mounted on the support component. By rotating the driving handle, the intermediate gear can be driven to rotate, thereby driving the rotating disk to rotate.

[0021] By adopting the above technical solution, the present invention sets the first driving component as a driving handle, which allows for more accurate angle calibration by manual rotation of the mechanism. Furthermore, by setting a transmission gear set to drive the rotating disk, the invention is more labor-saving and easier to operate.

[0022] In the preferred embodiment of the above-mentioned auxiliary assembly device, the lifting mechanism includes a scissor lift frame, a second driving component, a first top slide rail, a second top slide rail, a first bottom slide rail, and a second bottom slide rail. The first top slide rail and the second top slide rail are both fixedly connected to the bottom of the angle calibration mechanism. The first top slide rail and the second top slide rail extend along the first horizontal direction and are spaced apart along the second horizontal direction. The first bottom slide rail and the second bottom slide rail are both fixedly connected to the movable base. The first bottom slide rail and the second bottom slide rail extend along the first horizontal direction and are spaced apart along the second horizontal direction. The bottom of the scissor lift frame is provided with a first bottom sliding post and a second bottom sliding post. The first bottom sliding post is inserted into the first bottom slide rail and can slide along the length direction of the first bottom slide rail. There are two first bottom sliding posts, spaced apart along the length direction of the first bottom slide rail. The second bottom sliding post is inserted into the second bottom slide rail. The second top slide is inserted into the first top slide and can slide along the length of the second bottom slide. There are two second bottom slides, which are spaced apart along the length of the second bottom slide. The top of the scissor lift is provided with a first top slide and a second top slide. The first top slide is inserted into the first top slide and can slide along the length of the first top slide. There are two first top slides, which are spaced apart along the length of the first top slide. The second top slide is inserted into the second top slide and can slide along the length of the second top slide. There are two second top slides, which are spaced apart along the length of the second top slide. The first end of the second driving member along the first horizontal direction is pivotally connected to the scissor lift or the movable base. The second end of the second driving member along the first horizontal direction is pivotally connected to the scissor lift. The second end of the second driving member can extend and retract to drive the scissor lift to rise and fall.

[0023] With the above technical solution, the present invention inserts the first and second top sliding columns of the scissor lift frame into the first and second top slide rails respectively, and inserts the first and second bottom sliding columns of the scissor lift frame into the first and second bottom slide rails respectively, and drives the scissor lift frame to rise and fall by extending and contracting the second driving component. The structure is simple and easy to operate.

[0024] In the preferred embodiment of the above-mentioned auxiliary assembly device, the wheel set includes a plurality of spaced universal wheels, and the universal wheels are provided with a locking mechanism, which can lock the universal wheels; and / or the number of the first locking hole and the second locking hole are both 24.

[0025] By adopting the above technical solution, the present invention can facilitate the movement and locking of the auxiliary assembly device by setting the wheel set as multiple universal wheels with locking mechanisms. By having 24 first locking holes and 24 second locking holes, the rotation angle of the torso can be precisely adjusted and the torso can be locked at a certain angle. Attached Figure Description

[0044] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0045] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that although the steps of the control method of the present invention are described in a specific order in this application, this order is not restrictive, and those skilled in the art can perform the steps in different orders without departing from the basic principles of the present invention.

[0046] It should be noted that in the description of this invention, terms such as "inner," "outer," "upper," "lower," "front," "rear," "left," and "right," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Based on the background art, which points out the problem of low assembly efficiency of the torso and measurement test platform for automotive crash test dummies, this invention provides an auxiliary assembly device for measuring automotive crash test dummies. The device utilizes a movable base and lifting mechanism to move the torso horizontally and vertically, thereby initially positioning the torso's fixed points with the fixed points on the measurement test platform. An angle calibration mechanism then rotates the torso to align it with the fixed points on the test platform. Finally, an assembly mechanism tightens the fasteners to securely connect the torso and the measurement test platform. This allows for the transportation of the torso, the assembly of the torso with the measurement test platform, and the measurement work to be completed by a single operator, significantly improving the assembly efficiency of the torso and the measurement platform, as well as the measurement efficiency of the torso, while saving manpower.

[0049] Specifically, such as Figures 1 to 4 As shown, the present invention provides an auxiliary assembly device for measuring a car crash dummy, comprising: a movable base 1, a lifting mechanism 2, an angle calibration mechanism 3, a bearing mechanism 4, and an assembly mechanism 5.

[0050] The movable base 1 has a self-locking wheel set at its bottom; the lifting mechanism 2 is installed on the movable base 1; the angle calibration mechanism 3 is installed on the top of the lifting mechanism 2, and the lifting mechanism 2 can move the angle calibration mechanism 3 up and down in the vertical direction; the bearing mechanism 4 is detachably fixedly installed on the angle calibration mechanism 3, and the torso 6 can be detachably fixedly installed on the bearing mechanism 4; the assembly mechanism 5 is set on the bearing mechanism 4, and the assembly mechanism 5 is used to tighten the fasteners connecting the torso 6 and the measuring experimental table.

[0051] The angle calibration mechanism 3 includes a support member 32, a fixed disk 33, a rotating disk 34, a locking pin, a first driving member 35, and a transmission gear set 36. The bottom end of the support member 32 is fixedly connected to the top end of the lifting mechanism 2. There are two support members 32, which are spaced apart along the first horizontal direction. There are two fixed disks 33, which are vertically arranged and are respectively disposed on the inner sidewalls of the two support members 32. There are two rotating disks 34, which are vertically arranged and are rotatably mounted on the two fixed disks 33. The rotation axis of the rotating disk 34 extends along a first horizontal direction. The fixed disk 33 is located between the support member 32 and the rotating disk 34. The rotating disk 34 and the fixed disk 33 are coaxially arranged. The fixed disk 33 is provided with a plurality of first locking holes 331, which are evenly distributed along the circumference of the fixed disk 33. The rotating disk 34 is provided with a plurality of second locking holes 341, which are evenly distributed along the circumference of the rotating disk 34. There are multiple locking pins, and the locking pins can pass into the first locking holes 331 and the second locking holes 341 to restrict the rotation of the rotating disk 34 relative to the first locking holes 331 and the second locking holes 341. The fixed disk 33 rotates, and a first connecting structure 37 is provided at the center of the rotating disk 34. The bearing mechanism 4 is provided with four second connecting structures 43. Two of the four second connecting structures 43 are spaced apart along the first horizontal direction, and the other two of the four second connecting structures 43 are spaced apart along the second horizontal direction, which is perpendicular to the first horizontal direction. When X-axis measurement is required, the two second connecting structures 43 distributed along the first horizontal direction can be detachably and fixedly connected to the first connecting structures 37 on the two rotating disks 34 respectively. When Y-axis measurement is required, the two second connecting structures 43 distributed along the second horizontal direction can be detachably and fixedly connected to the first connecting structures 37 on the two rotating disks 34 respectively. The first driving component 35 is installed on one of the supporting components 32. The first driving component 35 is driven to one of the rotating disks 34 through the transmission gear set 36 so as to drive the rotating disk 34 to rotate, thereby rotating the bearing mechanism 4 and the torso 6 installed on the bearing mechanism 4, and thus calibrating the angle of the torso 6.

[0052] After leaving the factory, the torso 6 needs to be assembled onto a measuring test bench for measuring parameters such as the center of mass and moment of inertia, so as to ensure that the data of the torso 6 are close to those of a real human body. In the existing technology, due to the large weight and volume of the torso 6, it is necessary for 2 to 3 people to first transport the torso 6 to the measuring test bench, and then have two people lift the torso 6 to align the fixing points on the torso 6 with the fixing points on the measuring test bench. Both the fixing points on the torso 6 and the fixing points on the measuring test bench are provided with multiple bolt holes 62 arranged opposite to each other. Figure 10(There are 4 bolt holes in the middle). Then another person screws the bolts into the bolt holes 62 to fix the torso 6 to the measuring experimental platform. Moreover, because there are 4 bolt holes 62, each time a bolt is tightened, the bolt hole 62 needs to be aligned. Therefore, the staff needs to make multiple fine adjustments to the position of the torso 6, which will consume a lot of manpower and resources. In addition, the assembly efficiency of the torso 6 is extremely low.

[0053] For example, such as Figures 1 to 4 as well as Figure 10 As shown, the first horizontal direction of the present invention is the left-right direction, and the second horizontal direction is the front-back direction. The auxiliary assembly device of the present invention includes, from bottom to top, a movable base 1, a lifting mechanism 2, an angle calibration mechanism 3, a bearing mechanism 4, and an assembly mechanism 5. The bottom of the movable base 1 is a set of wheels with a self-locking function, which allows the auxiliary assembly device to move freely and lock in a certain position. The lifting mechanism 2 can move the angle calibration mechanism 3, the bearing mechanism 4, the assembly mechanism 5, and the torso 6 up and down. The angle calibration mechanism 3 can rotate the fixedly connected bearing mechanism 4 and torso 6. The assembly mechanism 5 can tighten the fasteners connecting the torso 6 to the measuring experimental table (e.g., ...). Using bolts or screws, the torso 6 can be moved horizontally and vertically via a movable base 1 and a lifting mechanism 2, thus initially positioning the fixed point of the torso 6 with the fixed point of the measuring experimental table. Then, the torso 6 is rotated by an angle calibration mechanism 3 to align the four bolt holes 62 on the torso 6 with the four bolt connection holes on the measuring experimental table. Finally, the bolts are tightened by an assembly mechanism 5 to fix the torso 6 to the measuring experimental table. This allows the transportation of the torso 6, the assembly of the torso 6 with the measuring experimental table, and the measurement work to be completed by a single person, greatly improving the assembly efficiency of the torso 6 with the measuring experimental table and the measurement efficiency of the torso 6, and saving manpower.

[0054] It should be noted that the present invention does not limit the number of bolt holes 62 on the torso 6. For example, those skilled in the art can set the number of bolt holes 62 on the torso 6 to 3 or 5, etc. Such adjustments and changes to the specific number of bolt holes 62 on the torso 6 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0055] For example, such as Figure 4As shown, the angle calibration mechanism 3 of the present invention has a horizontally arranged base plate 31, two vertically arranged support members 32 are spaced apart at the left and right ends of the base plate 31 in the left-right direction, two vertically arranged fixed disks 33 have their central axes coaxially arranged and extend in the left-right direction, and the two fixed disks 33 are located between the two support members 32, that is, the left fixed disk 33 is located to the right of the left support member 32, and the right fixed disk 33 is located to the left of the right support member 32. The central axes of the two vertically arranged rotating disks 34 are coaxially arranged and extend in the left-right direction. Extending in the direction, the two fixed disks 33 and the two rotating disks 34 are coaxially arranged. The rotating disk 34 on the left is located to the right of the fixed disk 33 on the left, and the rotating disk 34 on the right is located to the left of the fixed disk 33 on the right. That is, the fixed disk 33 is located between the support member 32 and the rotating disk 34. A horizontally arranged fixed rod 332 is provided on the central axis of the fixed disk 33. One end of the fixed rod 332 is fixedly connected to the support member 32, and the other end of the fixed rod 332 is provided with a bearing. The rotating disk 34 is mounted on the bearing, so that the rotating disk 34 can rotate relative to the fixed disk 33.

[0056] For example, such as Figure 4 As shown, a plurality of first locking holes 331 on the fixed disk 33 of the present invention are evenly arranged in a circle along the circumference of the circular sidewall of the fixed disk 33, and the first locking holes 331 penetrate the fixed disk 33 in the left-right direction. The rotating disk 34 is also provided with a circle of second locking holes 341 corresponding to the first locking holes 331. The locking pin (not shown in the figure) can pass through the first locking hole 331 and be inserted into the second locking hole 341, thereby locking the rotating disk 34 and restricting the rotating disk 34 from rotating relative to the fixed disk 33.

[0057] For example, such as Figure 4 and Figure 5 As shown, the first connecting structure 37 on the rotating disk 34 of the present invention is arranged in the left-right direction, and one end of the first connecting structure 37 is located at the center of the rotating disk 34, while the other end of the first connecting structure 37 is a free end and is symmetrically arranged with the other end of the opposite first connecting structure 37. Figure 4 In the middle view, on the left side of the base plate 31, from left to right, there is a set of support members 32, fixed disk 33, rotating disk 34 and first connecting structure 37. On the right side of the base plate 31, from right to left, there is a set of support members 32, fixed disk 33, rotating disk 34 and first connecting structure 37 symmetrically arranged.

[0058] For example, such as Figure 5 As shown, a second connecting structure 43 extending horizontally is provided on each of the four sides of the bearing mechanism 4 (front, back, left, and right). First, two second connecting structures 43 distributed in the left-right direction are fixedly connected to two first connecting structures 37 on the angle calibration mechanism 3 using bolts. Figure 1As shown, when the torso 6 is mounted onto the support mechanism 4, the top of the torso 6 faces right and the abdominal cavity of the torso 6 faces left, as... Figure 10 As shown, the fixation point of torso 6 is located inside the thoracic cavity of torso 6. When X-axis measurements are required, as... Figure 1 As shown, the moving auxiliary assembly device connects the fixed point of the torso 6 with the fixed point of the measuring experimental table. Then, the torso 6 is rotated by the angle calibration mechanism 3 for fine adjustment, aligning the bolt holes 62 of the torso 6 with the bolt connection holes of the measuring experimental table. Finally, the bolts are tightened to fix the torso 6 onto the measuring experimental table. Then, the torso 6 is disconnected from the bearing mechanism 4, and the auxiliary assembly device is removed, so that the torso 6 can be measured in the X-axis direction.

[0059] After the X-axis measurement is completed, the Y-axis measurement needs to be performed. At this time, the auxiliary assembly device is moved to the torso 6, and then the torso 6 is fixed to the bearing mechanism 4. Then, the connecting bolts between the torso 6 and the measuring experimental table are loosened, and the auxiliary assembly device is moved outside the measuring fixture. The two first connecting structures 37 on the angle calibration mechanism 3 are then connected to the... Figure 5 Disconnect the two second connecting structures 43 distributed along the left and right directions, remove the bearing mechanism 4 horizontally, and then rotate the bearing mechanism 4 counterclockwise by 90° in the horizontal direction, that is, so that the top of the torso 6 faces backward and the abdominal cavity of the torso 6 faces forward. Then install the bearing mechanism 4 onto the angle calibration mechanism 3, so that... Figure 5 Two second connecting structures 43 distributed along the front-back direction are fixedly connected to two first connecting structures 37 on the angle calibration mechanism 3. After fixing, the torso 6 on the bearing mechanism 4 is rotated 90° by the angle calibration mechanism 3 so that the top of the torso 6 faces upward. Then, the auxiliary assembly device is moved to the measuring experimental table. The auxiliary assembly device is moved to align the fixing point of the torso 6 with the fixing point of the measuring experimental table. The torso 6 is then rotated by the angle calibration mechanism 3 for fine adjustment so that the bolt hole 62 of the torso 6 is aligned with the bolt connection hole of the measuring experimental table. Finally, the bolts are tightened to fix the torso 6 to the measuring experimental table. Then, the torso 6 is disconnected from the bearing mechanism 4 and the auxiliary assembly device is removed. The torso 6 can then be measured in the Y-axis direction.

[0060] For example, such as Figures 2 to 4 As shown, the first driving member 35 of the present invention is mounted on the support member 32 located on the left side, and the transmission gear set 36 is also mounted on the support member 32 located on the left side. The first driving member 35 can drive the transmission gear set 36 to rotate, thereby driving the rotating disk 34 and the torso 6 mounted on the bearing mechanism 4 to rotate.

[0061] It should be noted that the present invention does not limit the number of the first keyhole 331 and the second keyhole 341. For example, those skilled in the art can set the number of the first keyhole 331 and the second keyhole 341 according to the size of the fixed plate 33 and the rotating plate 34 and the size of the keyhole. Such adjustment and change of the specific number of the first keyhole 331 and the second keyhole 341 does not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0062] Preferably, the number of the first keyhole 331 and the second keyhole 341 in this invention are both 24.

[0063] By setting both the first locking hole 331 and the second locking hole 341 to 24, the locking accuracy of the rotating disk 34 can be improved, enabling the rotating disk 34 to lock even with extremely small adjustments.

[0064] It should be noted that the present invention does not limit the form of the first connecting structure 37 and the second connecting structure 43. For example, those skilled in the art can set the first connecting structure 37 and the second connecting structure 43 as a slot and a post, and connect them by snap-fit. Alternatively, the first connecting structure 37 and the second connecting structure 43 can be set as a connecting post and a slot, and connected by plug-in and bolt, etc. Such adjustments and changes to the specific form of the first connecting structure 37 and the second connecting structure 43 do not deviate from the principle and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0065] Preferably, such as Figures 3 to 5 As shown, the first connecting structure 37 of the present invention is a connecting post extending in a first horizontal direction. A slot 371 is provided at one end of the connecting post away from the rotating disk 34. A first through hole 372 is provided in the connecting post in a vertical direction at a position corresponding to the slot 371. The top and bottom of the connecting post are set as horizontal planes at positions corresponding to the first through hole 372. The second connecting structure 43 is a horizontally arranged connecting plate. A second through hole 431 is provided on the connecting plate. The connecting plate is inserted into the slot 371, and the first through hole 372 is aligned with the second through hole 431.

[0066] For example, such as Figures 3 to 5As shown, the connecting column of the present invention is installed horizontally at the center of the rotating disk 34. The other end of the connecting column is a free end, and a slot 371 extending horizontally is provided on the free end. The two connecting plates of the bearing mechanism 4 distributed in the left and right directions can be freely inserted into the slots 371 of the two connecting columns respectively. The free end of the connecting column is provided with a first through hole 372 extending vertically through the free end. The first through hole 372 communicates with the slot 371. The connecting plate is provided with a second through hole 431. When the connecting plate is inserted into the slot 371, the first through hole 372 and the second through hole 431 can be aligned, so that the connecting plate and the connecting column can be fixedly connected by bolts to fix the bearing mechanism 4 onto the angle calibration mechanism 3.

[0067] Preferably, such as Figure 4 As shown, the first driving component 35 of the present invention is a driving handle. The driving handle includes a handle portion 351, a connecting portion 352, and a driving portion 353 connected in sequence. The handle portion 351 and the driving portion 353 both extend along a first horizontal direction, and the connecting portion 352 extends along a second horizontal direction. The driving portion 353 is rotatably mounted on the support component 32. The handle portion 351 and the connecting portion 352 are located on the outside of the support component 32. The driving end of the driving portion 353 passes through the support component 32 and extends into the inside of the support component 32. The transmission gear set 36 includes a first tooth structure 361, an intermediate gear 362, and a second tooth structure 363 that are connected in sequence. The first tooth structure 361 is disposed on the driving end of the driving portion 353, and the second tooth structure 363 is disposed on the rotating disk 34. The intermediate gear 362 is rotatably mounted on the support component 32. By rotating the driving handle, the intermediate gear 362 can be driven to rotate, thereby driving the rotating disk 34 to rotate.

[0068] For example, such as Figure 4 As shown, the handle portion 351, connecting portion 352 and driving portion 353 of the drive handle of the present invention are connected in a Z-shape. The driving portion 353 is rotatably and vertically mounted on the support member 32 located on the left side in the horizontal direction. The first tooth structure 361 is provided at the rightmost end of the driving portion 353, and the second tooth structure 363 is provided on the outer circumferential wall of the rotating disk 34. The intermediate gear 362 meshes with the first tooth structure 361 and the second tooth structure 363 respectively. By rotating the drive handle, the intermediate gear 362 can be driven to rotate, thereby driving the rotating disk 34 to rotate.

[0069] Preferably, such as Figure 3 , Figures 5 to 7As shown, the assembly mechanism 5 of the present invention includes a slide rod 51, a slider 52, an adjusting rod 53, and an assembler 54. The slider 52 is mounted on the slide rod 51 and can slide relative to the slide rod 51 along the length direction of the slide rod 51. The assembler 54 is mounted on the top end of the adjusting rod 53 and can rotate relative to the adjusting rod 53. The assembler 54 is used to tighten the fasteners connecting the torso 6 and the measuring experimental table. The bottom end of the adjusting rod 53 is pivotally connected to the slider 52 so as to adjust the angle of the assembler 54. The bearing mechanism 4 is provided with a slide groove 45 extending along the first horizontal direction. There are two slide grooves 45, which are arranged opposite each other along the second horizontal direction. The slide rod 51 extends along the second horizontal direction, and the two ends of the slide rod 51 are respectively inserted into the two slide grooves 45. The slide rod 51 can slide along the length direction of the slide groove 45 to adjust the distance between the assembler 54 and the torso 6.

[0070] For example, such as Figure 3 , Figures 5 to 7 As shown, the bearing mechanism 4 of the present invention is provided with a sliding groove 45 extending in the left-right direction, and the number of sliding grooves 45 is two spaced apart in the front-back direction. The sliding rod 51 extends in the front-back direction, and both ends of the sliding rod 51 extend into the two sliding grooves 45 respectively, so that the sliding rod 51 can slide in the left-right direction. The slider 52 is mounted on the sliding rod 51, so that the slider 52 can slide in the front-back direction. The bottom end of the adjusting rod 53 is pivotally connected to the slider 52, so that the assembler 54 can rotate in the left-right direction. The assembler 54 is mounted on the adjusting rod. The top of the adjusting rod 53 is rotatable relative to the adjusting rod 53. This structural design allows the assembler 54 at the top of the adjusting rod 53 to move freely in the front-back and left-right directions. It also allows the assembler 54 to rotate in the left-right direction. After the fixed point of the torso 6 is positioned with the fixed point of the measuring experimental table, the assembler 54 moves freely and extends into the torso 6. Rotating the assembler 54 aligns it with the connecting bolts that connect the torso 6 and the measuring experimental table. Rotating the assembler 54 again allows the bolts to be tightened easily.

The first connector 541 and the second connector 542 are respectively located on both sides of the through hole. The first connector 541 can be used to install a tool for tightening fasteners, and the second connector 542 can be used to install a wrench. By rotating the wrench, the assembler 54 and the tool are rotated to tighten the fasteners.

[0072] For example, such as Figure 6As shown, the through hole (not shown in the figure) on the adjusting rod 53 of the present invention extends through the top end of the adjusting rod 53 in the left-right direction. The assembler 54 is rotatably installed in the through hole. The first connector 541 of the assembler 54 is located on the right side of the through hole, and the second connector 542 of the assembler 54 is located on the left side of the through hole. The first connector 541 can be fitted with an Allen wrench, and the second connector 542 can be fitted with a rotary wrench. After the fixing point of the torso 6 and the fixing point of the measuring experimental table are positioned, the assembler 54 and the Allen wrench are rotated by rotating the wrench, thereby tightening the bolts and fixing the torso 6 to the measuring experimental table.

[0073] Preferably, the assembler 54 of the present invention is configured to be telescopic along its length.

[0074] By configuring the assembler 54 to be able to extend and retract along its length, the usable length of the assembler 54 can be increased, making the assembler 54 more flexible and convenient to use and improving assembly efficiency.

By extending and contracting, the two second driving components 22 can bring the first connecting rod 221 and the second connecting rod 222 closer together and further apart, thereby causing the first front support rod 211, the second front support rod 212, the first rear support rod 213 and the second rear support rod 214 to rotate relative to the connecting shaft 215, thereby causing the scissor lift frame 21 to rise and fall in the vertical direction.

[0083] It should be noted that the present invention does not limit the type of the second driving component 22. For example, those skilled in the art can set the second driving component 22 as an electric pneumatic jack or a hydraulic jack, etc. Such adjustments and changes to the specific type of the second driving component 22 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.
