Vehicle-mounted device for fixing road spectrum collecting equipment

Abstract

The invention relates to a vehicle-mounted device for fixing road spectrum collecting equipment. The vehicle-mounted device comprises a horizontally-arranged supporting plate. A thread hole for mounting of the road spectrum collecting equipment is formed in the supporting plate. The front end of the supporting plate is connected with a downward bottom support component. The end, far away from the supporting plate, of the bottom support component is provided with a through hole for being connected with a front row seat sliding track. The back end of the supporting plate is connected with an upward top supporting support component. The upper end of the top supporting support component is connected with a flexible joint through a ball head universal joint. The upper end face of the flexible joint is used for abutting against a vehicle top in an attaching mode. According to the scheme, the vehicle mounting problem of the road spectrum collecting equipment is solved, the road spectrum collecting equipment can be effectively fixed, free placing of the road spectrum collecting equipment in a vehicle is avoided, and test data accuracy and reliability are guaranteed.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a vehicle-mounted device for fixing road spectrum collection equipment. Background technique [0002] The collection of road load spectrum is an extremely important work in the process of automobile research and development. It is one of the important means to study the reliability of the whole vehicle. It not only provides a scientific basis for the fatigue life design of the whole vehicle and parts, but also makes the accelerated durability sex road test possible. [0003] At present, major domestic automobile companies have carried out road spectrum collection work one after another. However, because there is no special device for fixedly placing road spectrum collection equipment in the car during road spectrum collection, engineers generally place the collection equipment in the car at will, such as Place it on the passenger seat or on the rear seat or on the floor.

Problems solved by technology

[0003] At present, major domestic automobile companies have carried out road spectrum collection work one after another. However, because there is no special device for fixedly placing road spectrum collection equipment in the car during road spectrum collection, engineers generally place the collection equipment in the car at will, such as Place it on the passenger seat or on the rear seat or on the floor

In the case of no special fixing device, although the method of randomly placing the collection equipment in the vehicle is simple and convenient, it has the following disadvantages: 1. Since the collection equipment is not fixed, when collecting some strengthened and durable road surfaces, due to road excitation If it is too large, it will cause the acquisition equipment to shake left and right and vibrate up and down in the car, which will not only make the acquisition equipment easy to damage and shorten the service life, but also cause the acquisition equipment and the line connectors of each channel to loosen or fall off, resulting in interruption and loss of data during the data acquisition process and distortion; 2. During the acquisition process, the acquisition equipment is constantly bumped and shaken, and the terminal pins at the wire connectors of each channel are easily bent and deformed under constant stress, resulting in poor contact, data loss or distortion
