Constant-temperature and constant-humidity environment test box for vehicle-mounted satellite positioning terminal inspection

Abstract

The invention discloses a constant-temperature and constant-humidity environment test box for vehicle-mounted satellite positioning terminal inspection. The test box comprises a box body pedestal, thetop of the box body pedestal is fixedly connected with a test box body, the bottom of the inner cavity of the test box body is fixedly connected with a supporting spring seat, two sides of the bottomof the inner cavity of the supporting spring seat are fixedly connected with buffer springs, the top of each buffer spring is fixedly connected with a supporting movable rod, and the tops of the supporting movable rods are fixedly connected with a terminal placement seat. According to the invention, the vehicle-mounted satellite positioning terminal is placed in the terminal placement seat and isfixed through a fastening clamping plate, a vibration motor is started, the vibration environment of a vehicle is simulated, the vibration resistance of the vehicle-mounted satellite positioning terminal is tested, and the problems that the existing test device is single in function, cannot meet various data tests and is inconvenient to use, and a plurality of experimental devices are required tobe matched during various data tests, so that the cost is high, the operation is troublesome, and the influence on test data is relatively large are solved.

Description

technical field [0001] The invention relates to the technical field of environmental test chambers, in particular to a constant temperature and humidity environmental test chamber for inspection of vehicle-mounted satellite positioning terminals. Background technique [0002] The environmental test chamber uses scientific and technological means to simulate the natural environment and climate, which is destructive to modern industrial products. The representative tests of the environmental test chamber include low pressure (high altitude) test, high temperature test, low temperature test, thermal shock test, solar radiation ( Sunshine) test, rain test, moisture test, mildew test, salt spray test, sand and dust test, etc., the test site of the environmental test should be widely representative, can carry out as many test items as possible, and should be compared with the future The possible combat environment is as close as possible, but the environmental test field is often ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a constant temperature and humidity environment test box for vehicle-mounted satellite positioning terminal inspection, which has the advantages of multi-function, and solves the problem that the existing test device has single function and cannot meet various data tests. The cooperation of multiple experimental devices is not only costly, but also troublesome to operate, and has a great impact on the test data
