Abstract

The invention discloses a pedestrian protecting vehicle scriber used for a collision test, which comprises a movable base arranged in the Y direction, a horizontal moving rack, a longitudinal moving rod and a scribing rod, wherein the movable base is provided with a self-arranged leveling and fixing device; the horizontal moving rack and the movable base are in Y-direction sliding fit; a Z-direction extending vertical strut is fixed on the horizontal moving rack; the longitudinal moving rod is horizontally arranged on the vertical strut along the X direction; the longitudinal moving rod can horizontally slide along the X direction and the Z direction on the vertical strut and is locked and positioned; the scribing rod is arranged on one end of the longitudinal moving rod by a universal joint; and a space angle between the scribing rod and the longitudinal moving rod can be regulated at will. The pedestrian protecting vehicle scriber has the characteristics of low working intensity, high scribing efficiency and high scribing precision, is convenient and simple to operate, is convenient to move and saves space, can be made of belt trough aluminium profile, aluminium alloy plates and few steel materials to guarantee integral strength and have portability. The pedestrian protecting vehicle scriber is suitable for various vehicle collision test processes to serve as an auxiliary tool to carry out pedestrian protecting scribing operation.

Description

technical field [0001] The invention relates to the field of safety tests, in particular to auxiliary tools used in automobile collision tests, in particular to a pedestrian protection vehicle liner for collision tests. Background technique [0002] The protection of pedestrians in the process of automobile crash test has attracted more and more attention. At present, in the relevant laws and regulations in force in China, it is stipulated that the test area of ​​the front of the car needs to be divided before the test. These test areas are generally determined by the front, rear and side reference lines of the engine hood, the upper and lower reference lines of the bumper, the boundary lines of the corners of the bumper, and the envelope reference lines. Although the regulations stipulate these lines, they do not put forward normative requirements for the marking auxiliary tools, so there is no special marking instrument, and the marking process is generally carried out by...
