Description

Technical Field

[0001] The present disclosure relates to the technical field of environmental and reliability testing, and particularly to a complex environment test system. Background Art

[0002] As a key part of environmental testing, comprehensive testing is an effective means to evaluate the reliability of products. According to different test requirements, some products need to undergo single environment tests, while others need to undergo complex environment tests. Among them, single environments include: vibration environment, shock environment, atmospheric environment, pressure environment, etc. Comprehensive environment testing refers to the testing in which two or more factors act on the product simultaneously. There are corresponding test equipment for different types of tests, such as: vibration tables for simulating vibration environments, high and low temperature and humidity test chambers for changing parameters such as temperature and humidity, etc. In the existing test technologies, a single device can complete a certain environmental test, and a combination of devices can complete complex type tests.

[0003] Common comprehensive environment test systems face some technical problems. Due to the limited floor space resources of the comprehensive system, there are often problems such as the vibration table being unable to generate sufficient thrust because the product is too heavy, and the product size being too large to fit within the size of the temperature and humidity test chamber and thus unable to be measured. Moreover, often due to the inconsistent interfaces or the devices not being within the same system range, the linkage efficiency of the comprehensive test is low. For example, temperature and humidity tests and vibration tests cannot be carried out on the same product in the same system as two-axis vibration.

[0004] Based on this, there is an urgent need for a complex environment test system that can adapt to different product specifications, includes multiple test devices within the same system, and can enhance the device linkage efficiency. Summary of the Invention

[0018] Furthermore, a microwave shielding anechoic chamber is included. The microwave shielding anechoic chamber is located on one side of the temperature and humidity test chamber, on the same first ground rail group as the temperature and humidity test chamber, and is configured to be able to move and position along the length direction of the first ground rail group.

[0036] To make the objectives, technical solutions and advantages of the present disclosure clearer and more understandable, the following further elaborates on the present disclosure in detail with reference to specific embodiments and the accompanying drawings.

[0037] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings understood by those with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar terms used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Connection" or "coupling" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative position relationships, and when the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0038] As a key part of environmental testing, comprehensive testing is an effective means to evaluate the reliability of products. However, as described in the background art section, the technical problems of common comprehensive environmental testing systems are as follows: due to limited land resources in the comprehensive system, there are often problems such as the vibration table being unable to generate sufficient thrust because the product is too heavy, and the product specifications being too large to be measured beyond the size of the temperature and humidity test chamber. Moreover, often due to inconsistent interfaces or the reason that the devices are not within the same system range, the linkage efficiency of comprehensive testing is low.

[0039] In the same comprehensive experimental system, if the temperature and humidity test chamber and the vibration table are selected according to the maximum product specifications, it will occupy a huge space, require high costs, waste too many resources, and affect the accuracy of small product tests. Moreover, the linkage efficiency among the various test devices in the same comprehensive testing system is not high, and usually only single-table vibration and temperature and humidity comprehensive tests can be completed, and complex environmental tests such as multi-vibration table combined thrust and temperature and humidity comprehensive tests, and temperature and humidity and vibration with two or more axes cannot be achieved.

[0040] In view of the problems of the above technologies, the present application considers placing a temperature and humidity test chamber and multiple vibration tables in the same system, and compactly arranging the overall system through multiple ground rail structures, efficiently switching test equipment and being able to improve the linkage efficiency. Among them, the main body of the temperature and humidity test chamber is designed to be large-sized and divided into multiple sub-chambers, and the corresponding number of sub-chambers is selected for partition testing according to the sizes of different products; the vibration table can move and position along the ground rail, and can be rotated to be horizontal or vertical and can be combined with each other to complete multi-axis vibration tests, or combined with the temperature and humidity test chamber, so that single-axis or multi-axis vibration tests can be carried out in parallel during the temperature and humidity test.

[0041] Hereinafter, through specific embodiments and in combination with Figures 1-7 the technical solution of the present invention will be further described in detail.

[0042] The present invention provides a complex environment test system, including:

[0044] Vibration tables 2, a plurality of the vibration tables 2 are placed on the first ground rail group 51 and are configured to be able to move and position along the length direction of the first ground rail group 51. It can be Figure 1 seen that the first ground rail group 51 is divided into three groups. For the convenience of distinction, the three ground rails of the first ground rail group 51 are numbered 51a, 51b, and 51c from top to bottom hereinafter. The vibration table 2 includes a vibration table main body 21 and a vibration table base 22, and the vibration table main body includes a vibration table surface 211; the vibration table main body 21 is configured to be able to rotate relative to the vibration table base 22 so that the vibration table surface 211 is parallel to or perpendicular to the foundation 5;
