Problems solved by technology

[0003] At present, in the side pillar impact test of the trolley, in order to standardize the actual vehicle pillar impact data, the door components of the real vehicle are used for the test. To do one test, one door component (including the door and the interior) needs to be destroyed, and the cost is very high. And the test cycle is long

Abstract

The invention discloses a pillar impact tool and a test trolley for simulating a side impact test of a car, comprising a side door frame, a rocker hinge seat, a door frame fixed hinge seat, a cylindrical seat and a pillar impact installation base, and the cylindrical seat is installed on On the post strike installation base, there are side door frames on both sides of the post strike installation base. The side door frame is hinged with the door frame fixed hinge seat. The door frame fixed hinge seat is installed on the post strike installation base. Rod, the slide bar passes through the cross rocker, and the cross rocker is hinged on the hinged seat of the rocker. A pillar impact tooling and a test trolley for simulating a side impact test of a car according to the present invention can simulate the deformation of the car door under the working condition of an automobile side pole impact to the greatest extent, and cooperate with the test platform to standardize the test data of the real vehicle side pole impact , which greatly reduces the cost of the real vehicle test, and the structure is ingenious, the installation is convenient, and the test efficiency is improved.

Description

technical field [0001] The invention relates to a pillar impact tool and a test trolley for simulating a side impact test of a car, and belongs to the field of passive safety of automobiles. Background technique [0002] In a vehicle single-vehicle accident, collisions with large trees, utility poles, sign poles and other objects due to side slipping are considered side column collisions. These obstacles have huge rigidity but small contact surfaces, and the local intrusion into the side of the vehicle is much greater than that of the side Therefore, the injuries caused to the occupants in the vehicle are very serious. In order to further improve the protection performance of the vehicle, the side pillar impact test has begun to appear, which has higher requirements for the side collision protection performance of the vehicle. Therefore, in the process of passive safety development of automobiles, the side column impact device of the trolley has also become the focus of curr...
