Embodiment 1

[0035] figure 1 is a schematic perspective view of the height measuring aid according to an embodiment of the present invention, combined with figure 1 To illustrate, the height measurement aid that can be used for the dummy head drop calibration test can include: a support arm 2, a positioning member 3 and a base 1 that can be used for support. A support arm 2 can be used for mounting at said base 1 . And the support arm 2 can keep the dummy head 4 at the specified height of the drop calibration test relative to the drop impact plane of the drop calibration test. The positioning part 3 can be fixedly connected with the support arm 2 and installed vertically, and the positioning part 3 can have a first positioning part 312 that marks the height of the lowest part of the dummy head 4 and marks the height of the dummy head 4 The second positioning part 311 at the height of other parts. The first positioning part 312 and the second positioning part 311 can be used to keep the ...

Embodiment 2

[0038] continue to combine figure 1 For illustration, the unexplained part of this embodiment may be the same as that of Embodiment 1, and the positioning member 3 may be a long-arm-shaped positioning member and arranged in a stepped shape. The first positioning portion 312 and the second positioning portion 311 may be two horizontal planes disposed on the top of the positioning member 3 .

[0039] In the case not shown in the accompanying drawings, further, the first positioning portion 312 may be shaped to position and support the forehead 41 of the dummy head 4 . The second positioning portion 311 can be shaped to position and support the nose portion 42 of the dummy head 4 , and the dummy head 4 can be set downward.

[0040] Preferably, the distance between the first positioning part 312 and the calibration platform may be 376 mm, and the distance between the second positioning part 311 and the calibration platform may be 388.7 mm.

[0041] Since the nose part 42 of the ...

Embodiment 3

[0043] figure 2 yes figure 1A schematic left side view of the height measuring aid is shown, represented by figure 1 go to figure 2 Continuing with the description, the unreleased part of this embodiment may be the same as that of Embodiment 1. The support arm 2 has a plurality of butt joints 21 that can be connected to the positioning member 3, so that the positioning member 3 is different from the When the butt joints 21 are connected, the positioning member 3 can keep the dummy head 4 at different specified heights of the drop calibration test relative to the drop impact plane of the drop calibration test.

[0044] continue to combine figure 2 To illustrate, further, the support arm 2 may be provided with a vertically arranged elongated through hole 22, a plurality of the butt joints 21 may be arranged at intervals along the vertical direction of the support arm 2, and the plurality of The abutting portion 21 may communicate with the elongated through hole 22 . The ...

Abstract

The invention provides a height measurement assisting tool used for a dummy head falling calibration test, and relates to a falling calibration test used for the dummy head. The height measurement assisting tool comprises a base; a supporting arm which is used for being installed on the base and enabling the dummy head to maintain the specific height of the falling calibration test relative to the falling impact plane of the falling calibration test; and a positioning member which is fixedly connected with the supporting arm and vertically installed, wherein the positioning member is provided with a first positioning part which indicates the height of the lowest part of the dummy head and a second positioning part which indicates the height of other parts of the dummy head, and the first positioning part and the second positioning part are used for enabling the dummy head to maintain the specific height of the falling calibration test. Compared with the method in the prior art that the dummy head is enabled to maintain the specific state before falling calibration of the dummy head, the efficiency of the height measurement assisting tool used for the dummy head falling calibration test is greatly enhanced.

Description

technical field [0001] The invention relates to a drop calibration test for a dummy head, in particular to a height measurement auxiliary device for a dummy head drop calibration test. Background technique [0002] Dummy is an important equipment for data collection in automobile crash tests (such as vehicle crash tests, sliding table tests, etc.). There are many types of sensors such as acceleration and displacement arranged inside the dummy. During the crash test, the state of the dummy directly affects the accuracy of data collection. Therefore, it is necessary to calibrate the dummy once after multiple crash tests. The head drop calibration test is one of the many calibration tests on the dummy, and its main purpose is to check the hardness of the head skin. [0003] The dummy head drop calibration test is to place the dummy's head at a specified height from the falling plane, and record the test data of all aspects of the dummy's head hitting the falling plane to che...
