Problems solved by technology
[0003] (1) The connection between the rope and the pendulum is through the buckle and the buckle hole. When releasing the pendulum, it is still necessary to manually untie the connection between the buckle and the buckle hole, which is inconvenient to operate;
[0004] (2) The lifting height of the pendulum cannot be displayed in real time, and manual measurement is required, which is likely to cause errors

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing of description:
[0026] Such as Figure 1~3 As shown, a car crash test dummy neck calibration equipment includes a bracket and a pendulum mechanism rotatably connected to the bracket. The pendulum mechanism includes a pendulum 8 that is rotatably arranged on the bracket and one end is used to install the dummy neck. The calibration device also includes a gear rod 9 arranged on the support for colliding with the pendulum 8, a lifting mechanism arranged on the support for lifting the pendulum 8, and a lifting mechanism for controlling the lifting mechanism to lift the pendulum 8 to a required height control system.
[0027] In this example, the bracket includes side brackets arranged on both sides of the calibration equipment, and each side bracket includes a base plate 1, a column 2 vertically arranged on the base plate 1, and first diagonal braces connected to the base plate...

The invention relates to an automobile bump test dummy neck calibrating device. The automobile bump test dummy neck calibrating device comprises a support and a pendulum hammer mechanism rotationally connected with the support. The pendulum hammer mechanism comprises a pendulum hammer which is rotationally arranged on the support and has one end used for installing a dummy neck portion. The calibrating device further comprises a shift rod arranged on the support for generating a bump with the pendulum hammer, a lifting mechanism arranged on the support for lifting the pendulum hammer and a control system used for controlling the lifting mechanism to lift the pendulum hammer to a needed height. The control system comprises a control apparatus arranged on the support for electrical connection with the lifting mechanism. The control apparatus comprises a control panel for inputting instruction information and a processor for processing the input information of the control panel and then sending an instruction to the lifting mechanism so as to control the operation of the lifting mechanism. The calibrating device provided by the invention is simple to operate, is time-saving and labor-saving and is stable in performance.
Description
technical field [0001] The invention belongs to the technical field of automobile safety detection, and in particular relates to a neck calibration device for an automobile collision test dummy. Background technique [0002] In the field of automobile safety detection technology, automobile crash test is an important test method to test the safety performance of automobiles, and the test dummy, as the basic tool of automobile collision test, plays a vital role in the development of automobile safety. For the dummy in the crash test, in order to ensure the accuracy of the test data, it must be recalibrated before each experiment. Among them, there are many calibration test index items for the neck of the dummy, and the design of the test bench is also complicated. In the prior art, there has been dummy neck calibration equipment, which adopts a bracket structure, installs an impact pendulum on the bracket, installs the dummy neck on the pendulum, lifts the pendulum manually,...
