Device for detecting automobile cab and front and rear end protecting device

Abstract

The invention discloses a device for detecting an automobile cab and a front and rear end protecting device. The detecting device structurally comprises a main body frame, wherein the main body frame is fixedly arranged on the ground and has certain height, length and width; a speed reducer is arranged at the upper end of the left side of the main body frame; a pendulum bob is arranged at the lower end of the speed reducer through a spindle elevating mechanism; a protecting device is further arranged on the pendulum bob; a hoisting motor is arranged at the upper part of the frame; a steel cable for hoisting the pendulum bob is arranged between the hoisting motor and the pendulum bob; an electric sucker is arranged at the rear end of the pendulum bob; a collider is arranged at the right end of the frame; an electric sucker is arranged at one end of the collider; the electric sucker is connected with the hoisting motor through a cable; a power-off protecting device is further arranged on the device; and a camera and a data acquisition system are arranged well before the experiment. The detecting device has the beneficial effects that the system can be used for easily observing the dynamic response and deformation situations of a sample in the collision process, has more acquired data, and is high in testing precision, simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a detection device for a vehicle, in particular to a detection test device for a frontal collision of an automobile cab and a detection test device for an automobile front and rear end protection device. Background technique [0002] The detection and test system of the frontal impact of the car cab and the detection and test system of the front and rear end protection devices of the car are an indispensable detection and test system in the safety performance test of the car collision. It is a necessary test responsible for checking the quality of the car products The device plays a very important role in promoting automobile manufacturers to improve automobile collision safety performance, thereby reducing occupant injuries and deaths in traffic accidents, and maintaining consumers' lives and national property. There are currently two types of detection test systems for frontal collisions of automobile cabs. [0003] One is a...
