Universal rack of automotive restraint system

Abstract

The invention discloses a universal rack of an automotive restraint system. The universal rack comprises a sliding table plate (1), an instrument plate cross beam (5), a steering column mounting frame (6) and a knee supporting frame (7), wherein the instrument plate cross beam (5) is supported through an instrument plate cross beam bracket (3) arranged on the sliding table plate (1), a plurality of mounting holes II are formed in the instrument plate cross beam (5), and the steering column mounting frame (6) and the knee supporting frame (7) are selectively mounted in the corresponding mounting holes II in the instrument plate cross beam (5); a safety belt fixing frame (8), a chair mounting frame (9) and an accelerator pedal bracket (4) which are used for simulating a real automobile are further arranged on the sliding table plate (1), and a plurality of mounting holes I (2) for mounting parts of various vehicle models are formed in the sliding table plate (1). The universal rack can be applied to experiments of the different vehicle models and is easy to built and adjust; by utilizing the universal rack, the experiments are accurate, technical risks are reduced, the development cost is saved, and the later changing cycle is shortened.

Description

Technical field [0001] The invention belongs to the field of automobile manufacturing, relates to the technical field of passive safety performance, and more specifically, relates to a universal bench for an automobile restraint system. Background technique [0002] In the development process of the automobile restraint system, in order to simulate the crash test environment of the whole vehicle, it is generally necessary to use a bench composed of the white body and the interior parts, and conduct tests on the accelerating pulley. However, in the early stage of vehicle development, especially during the selection phase of restraint system suppliers, it is necessary to understand the performance of different restraint systems under the corresponding working conditions of the vehicle collision to provide a basis for the selection of product platform parameters. However, since the body parts have not yet opened molds at this stage , The conditions for building a formal platform are...

AI Technical Summary

Problems solved by technology

However, in the early stage of model development, especially in the stage of restraint system supplier selection, it is necessary to understand the performance of different restraint systems under the corresponding working conditions of vehicle collisions, so as to provide a basis for product platform parameter selection. , the conditions for building a formal bench are not yet available, and it is very limited to carry out the pulley test on the relevant components of the restraint system at this stage

Moreover, the positions of the constraining components in different models are not uniform, making it difficult to restructure, high in cost, and unable to achieve the desired effect
