Embodiment

[0025] Embodiment: a kind of passenger car corner measuring device of this embodiment, such as figure 1 with figure 2 As shown, it includes a base, a bracket installed on the base and movable along the base, and a measuring panel 1 installed on the bracket. The base includes two guide rails 2 arranged in parallel, and two connecting rails are arranged between the guide rails. Rod 3, two connecting rods are respectively arranged at the front and rear ends of the guide rail and welded with the guide rail. It is erected on the guide rail at an angle of 60° with the guide rail. Roller devices are designed at both ends of the beam. The roller device is clamped on the guide rail and moves back and forth along the guide rail. There are two columns, which are symmetrically distributed and welded on the beam and perpendicular to the track. Plane, a lifting device is designed on the column; the measurement panel is installed on the column and perpendicular to the track plane, the meas...

Abstract

The invention discloses an angular point measuring device of a passenger car and an angular point measuring method. The angular point measuring device comprises a base, a support arranged on the base and a measuring panel arranged on the support. The base comprises two parallelly arranged guide tracks, a plurality of connecting rods are arranged between the guide tracks, the support comprises a beam and a lifting column, the beam is erected on the guide tracks and can move along the beam, the beam and the guide tracks form a 60-degree included angle, and the measuring panel is arranged on the column and perpendicular to a track plane. A two-dimensional movable measuring platform is adopted for simulating a collision process between pedestrians and a front bumper of the car so as to determine angular point positions. Determination of an angular point is changed into a direct collision measuring method from an indirect method through original laser radiation and observation of naked eyes, locating of angular points in a collision area of shanks of pedestrians in a pedestrian protection test is fully achieved, a measuring process is simple, and the measuring precision is high.

Description

technical field [0001] The invention relates to a measuring device, in particular to a corner point measuring device and a corner point measuring method of a passenger car with simple device and high measuring precision. Background technique [0002] In China, due to the complex road traffic conditions, the injuries suffered by pedestrians are becoming more and more prominent. According to the statistics of the national road traffic accidents in 2010 by the Ministry of Public Security, there were 3,906,164 road traffic accidents reported nationwide, a year-on-year increase of 35.9%. Among them, There were 219,521 road traffic accidents involving casualties, resulting in 65,225 deaths, 254,075 injuries, and a direct property loss of 930 million yuan. China also implemented GB / T24550-2009 collision protection for pedestrians on July 1, 2010. In order to strengthen the protection of pedestrians, the pedestrian protection test is an important means of pedestrian protection safet...
