The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the protection scope of the present invention.

[0024] As Figure 1 and Figure 2 shown, the present application provides a Hybrid III dummy neck calibration tooling, which includes a connection base 1 and a potentiometer support assembly 3.

[0025] The connection base 1 is disposed between the swing arm of the calibration device and the proximal thoracic end of the dummy cervical vertebra 2, and its function is to firmly connect the proximal thoracic end of the dummy cervical vertebra 2 to the swing arm, so as to ensure that the dummy neck can simulate the movement state under real collision conditions during the calibration test.

[0026] Among them, the fixed bracket 31 is connected to the connection base 1, and the movable bracket 32 is connected to the proximal head end of the dummy cervical vertebra 2 and can rotate relative to the fixed bracket 31. The angle sensor 33 is installed between the fixed bracket 31 and the movable bracket 32 and is used to measure the relative rotation angle between the two, so as to provide angle data support for the neck calibration test.

[0027] The Hybrid III dummy neck calibration tooling of the present application not only meets the high-precision requirements of neck calibration tests through optimized structural design, but also significantly reduces production costs and manufacturing difficulties.

[0028] As Figure 2 shown, in a specific embodiment of the present application, the fixed bracket 31 includes a first arm 311, a second arm 312 and a connecting rod 313. Among them, the axial direction of the connecting rod 313 is parallel to the axial direction of the dummy cervical vertebra 2 and is arranged at the ear side position of the dummy head, so as to facilitate capturing the bending or stretching movement of the dummy cervical vertebra 2 in the calibration test and will not interfere with the dummy cervical vertebra 2. One end of the first arm 311 is directly or through a coupling connected to the connection base 1, and the other end is connected to the connecting rod 313. The second arm 312 is also connected to the connecting rod 313 and maintains a certain interval from the first arm 311 on the connecting rod 313. The position of the second arm 312 corresponds to the proximal end of the dummy cervical vertebra 2. The fixed bracket 31 remains relatively stationary with the connection base 1, that is, remains relatively stationary with the proximal end of the dummy cervical vertebra 2. The angle sensor 33 is installed on the second arm 312 for monitoring and recording the change in the movement angle of the dummy cervical vertebra 2 in the calibration test.

[0029] As Figure 2 shown, in a specific embodiment of the present application, both the first arm 311 and the second arm 312 are slidably connected to the connecting rod 313 so as to adjust the specific connection positions of the first arm 311 and the second arm 312 corresponding to the lengths of different models of dummy cervical vertebra 2. In addition, limit pins are provided at both ends of the connecting rod 313 to prevent the first arm 311 and the second arm 312 from sliding out from both ends.

[0030] As Figure 2 shown, in a specific embodiment of the present application, the movable bracket 32 is specifically a movable pin. One end of the movable pin is a tip with a guiding function for accurately guiding the movable pin to insert into a preset mounting hole at the proximal end of the dummy cervical vertebra 2. And the movable pin is fixed in the mounting hole by a set screw, effectively preventing relative sliding between the movable pin and the mounting hole. By adjusting the axial position of the movable pin in the mounting hole, the spatial attitude of the connecting rod 313 can be controlled so that it always remains in a predetermined vertical plane. The connecting end of the movable pin is connected to the angle sensor 33, and the angle sensor 33 monitors the rotation angle of the dummy cervical vertebra 2 through the movable pin.

[0031] As Figure 3 and Figure 4As shown in the figure, in a specific embodiment of the present application, the connecting base 1 includes a base body 11 and side plates 12. One end of the base body 11 is connected to the swing arm of the calibration device, and the other end is connected to the proximal thoracic end of the dummy cervical vertebra 2, so as to ensure that the dummy cervical vertebra 2 can accurately simulate the movement state under real collision conditions during the calibration test. The side plate 12 has a third mounting hole 121, and the first arm 311 is connected to the side plate 12 through the third mounting hole 121. The side plate 12 is movably connected to the side of the base body 11, and the specific mounting position of the side plate 12 can be adjusted according to actual needs, so as to adapt to the lengths of different models of dummy cervical vertebra 2. The fixing bracket 31 is connected to the side plate 12. By adjusting the mounting position of the side plate 12, the working pose of the fixing bracket 31 can be adjusted to ensure the measurement accuracy of the angle sensor 33.

[0032] As Figure 3 and Figure 4 shown in the figure, in a specific embodiment of the present application, the base body 11 includes a first mounting hole 124 and a second mounting hole 122 arranged along the front-back direction of the dummy head. The first mounting hole 124 is closer to the front face position of the dummy head than the second mounting hole 122. The base body 11 is connected to the proximal thoracic end of the dummy cervical vertebra 2 through connectors arranged in the first mounting hole 124 and the second mounting hole 122; As Figure 1 and Figure 5 shown in the figure, during the bending test of the dummy cervical vertebra 2, the front face of the dummy head faces the swinging direction of the swing arm, and the projection distance of the axis of the second mounting hole 122 and the axis of the swing arm on the vertical plane is the first mounting distance; As Figure 6 and Figure 7 shown in the figure, during the stretching test of the dummy cervical vertebra 2, the front face of the dummy head faces away from the swinging direction of the swing arm, and the projection distance of the axis of the second mounting hole 122 and the axis of the swing arm on the vertical plane is the second mounting distance, where the first mounting distance is less than the second mounting distance. Specifically, the first mounting distance is 13.46 mm ± 0.5 mm, and the second mounting distance is 37.34 mm ± 0.5 mm, so as to ensure the accuracy and reliability of the calibration test data.

[0033] As Figure 1 shown in the figure, in a specific embodiment of the present application, the Hybrid III dummy neck calibration tooling further includes a fastener 13 for fixing the side plate 12. The side plate 12 is provided with a strip-shaped hole 123 extending along its length direction. The strip-shaped hole 123 is a long circular through-hole structure, and its length dimension is greater than the diameter of the fastener 13 to provide an adjustment space for the side plate 12 relative to the base body 11. The fastener 13 can be a standard bolt, which passes through the strip-shaped hole 123 and is in threaded connection with a threaded hole preset on the side of the base body 11, and the side plate 12 and the base body 11 are reliably fixed through a tightening operation.

[0034] In a specific embodiment of the present application, the Hybrid III dummy neck calibration tooling further includes a gasket (not shown in the figure) disposed between the connecting base 1 and the near-thoracic end of the dummy cervical vertebra 2. The gasket is provided with through holes for the screws connecting the dummy cervical vertebra 2 and the connecting base 1 and the neck cable to pass through. The gasket is made of a flexible material with appropriate elasticity and wear resistance, and its thickness is selected according to the actual working conditions. During the collision test, through the elastic deformation characteristics of its material, the gasket can effectively absorb and disperse the impact energy received by the dummy cervical vertebra 2, thereby reducing the stress concentration phenomenon at the connection part. At the same time, the flexible characteristics of the gasket ensure that while buffering the impact force, it will not interfere with the acquisition of test data. In addition, the setting of the gasket can also reduce the direct contact between the dummy cervical vertebra 2 and the connecting base 1, reduce the frictional loss between the two, and extend the service life of the tooling.

[0035] The present application also provides a calibration method for the Hybrid III dummy neck, including the following steps: First, install the dummy cervical vertebra 2. Connect and fix the near-thoracic end of the dummy cervical vertebra 2 to the lower end of the connecting base 1 through fasteners, and install the connecting base 1 on the working end of the calibration equipment swing arm.

[0036] Subsequently, install the potentiometer bracket assembly 3. Connect the first arm 311 of the fixed bracket 31 to the third mounting hole 121 of the side plate 12. Then, specifically select the corresponding installation position according to the test type. When performing the bending test of the dummy cervical vertebra 2, face the front face of the dummy head towards the swinging direction of the swing arm; or, when performing the tensile test of the dummy cervical vertebra 2, face the front face of the dummy head away from the swinging direction of the swing arm; connect the movable bracket 32 to the near-head end of the dummy cervical vertebra 2, and install an angle sensor 33 between the fixed bracket 31 and the movable bracket 32.

[0037] When adjusting the calibration equipment, place the swing arm against the honeycomb aluminum surface. By adjusting the connection between the near-thoracic end of the dummy cervical vertebra 2 and the connecting base 1, ensure that the axis of the swing arm is perpendicular to the reference plane of the dummy head. Lift the swing arm to an angle that meets the collision speed requirement and then release it, allowing it to freely fall under the action of gravity until the swing arm collides with the honeycomb aluminum. Take the initial moment when the swing arm contacts the honeycomb aluminum as the zero moment, collect and record the measurement data through the angle sensor 33, and obtain the relationship curve of acceleration, angle, torque and time. By analyzing this relationship curve, judge whether each parameter meets the preset calibration requirements. If all parameters meet the requirements, it is determined that the Hybrid III dummy neck calibration is qualified.

[0038] In a specific embodiment of the present application, a gasket is provided between the near-thoracic end of the dummy cervical vertebra 2 and the connection base 1 to reduce the direct contact between the dummy cervical vertebra 2 and the connection base 1, reduce the frictional loss between the two, and extend the service life of the tooling.

[0039] In a specific embodiment of the present application, the vertical error range between the axial direction of the swing arm and the reference plane of the dummy head is: -1° ≤ θ ≤ 1°.

[0040] Before implementing the calibration method for the Hybrid III dummy neck, it is necessary to perform necessary preprocessing on the dummy cervical vertebra 2 to ensure its structural integrity during the calibration process and prevent abnormal situations such as cracking. The specific implementation steps of the preprocessing are as follows: First, place the dummy cervical vertebra 2 in an environmental control box, maintain the temperature in the control box within the range of 20.6°C to 22.2°C, and control the relative humidity between 10% and 70% to ensure that the dummy cervical vertebra 2 reaches thermal and humidity equilibrium with the environment. The placement time of the dummy cervical vertebra 2 in the set environment shall not be less than 4 hours, and the calibration test environment shall maintain the same temperature and humidity conditions as the preprocessing environment. Subsequently, use a torque wrench to adjust the torque of the nut on the cable of the dummy cervical vertebra 2 so that the tightening torque of the nut is accurately controlled within the range of 1.36 Nm ± 0.27 Nm. The setting of this torque range not only ensures that the pre-tightening force of the cable can meet the calibration requirements but also avoids the stress concentration phenomenon caused by excessive tightening. Through the above preprocessing steps, the stability and reliability of the dummy cervical vertebra 2 during the calibration process can be effectively improved, ensuring the accuracy and repeatability of the calibration results.

[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
