Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0027] figure 1 It is a schematic diagram of the structure of the marking device for pedestrian protection. Such as figure 1 As shown, the present invention provides a method for pedestrian protection marking, including:

[0028] Rotate the first support 100 pivoted on the upper end of the second support 300, so that the angle between the first support 100 and the second support 300 remains at 130 degrees;

[0029] Set up the second pillar 300 with a length of 600mm vertically and touch the ground;

[0030] Make the plane where the first pillar 100 and the second pillar 300 are located parallel to the longitudinal direction of the car, so that the first pillar 100 with a length of 1000mm keeps in contact with the front end of the car;

Abstract

The invention discloses a pedestrian protection marking-out method and device. The method includes the steps that a first supporting column (100) pivoted to the upper end of a second supporting column (300) is rotated to keep the included angle between the first supporting column (100) and the second supporting column (300) 130 degrees; the second supporting column (300) with the length of 600 mm is vertically arranged and makes contact with the ground; the plane where the first supporting column (100) and the second supporting column (300) are located is kept parallel to the longitudinal plane of an automobile, and the first supporting column (100) with the length of 1000 mm is kept making contact with the front end of the automobile; the first supporting column (100) and the second supporting column (300) are pushed at the same time in the width direction of the automobile, and the curve of contact points between the first supporting column (100) and the front end of the automobile is recorded. The pedestrian protection marking-out method and device are used for marking a datum line of the front edge of an engine hood and solving the problem of marking inaccuracy in existing marking-out technologies.

Description

technical field [0001] The invention relates to the field of pedestrian protection, in particular to a method and device for pedestrian protection marking. Background technique [0002] In the pedestrian protection thigh crash test, the accuracy of the test area division directly affects the quality of the pedestrian protection crash test results, and also affects the development of pedestrian protection safety performance. The prior art uses an integrated marking tool to draw lines for pedestrian protection areas, including envelope lines, side reference lines, front edge reference lines of the hood, bumper upper and lower reference lines, and the like. The method for marking the reference line at the front edge of the engine hood is: the geometric trajectory of the contact point between a ruler with a length of 1000 mm and the front surface of the engine hood. The geometric trajectory is formed by the point of contact with the front edge of the hood when the straightedge ...
