AI Technical Summary
In existing technologies, the problem of overloaded experimental resources cannot be effectively solved, especially when the number of samples increases during the peak period of the project, which leads to waste of equipment and space, and the cost of adding equipment is high.
An environmental chamber for placing multiple samples was designed, including a frame and a sample rack. The frame is equipped with slide rails and a grid structure. The sample rack is slidably connected by the slide rails. The sample suspension system, consisting of uprights and inner rods, supports simultaneous testing of multiple samples. The frame is also equipped with ventilation holes and baffles to maintain stability.
It enables multi-sample testing during peak periods, while the chamber can be converted to a regular test chamber during off-peak periods, reducing equipment waste, improving resource utilization, and ensuring sample independence and test accuracy.

TECHNICAL FIELD
[0001] The utility model relates to environmental test equipment technical field, concretely relates to a kind of environmental box for testing electronic product. BACKGROUND
[0002] The electric control system in electronic product is one of the most core parts in product. Therefore, electric control reliability test is an indispensable link in the process of electronic product research and development. Electric control reliability test can ensure the stability and reliability of product under various extreme environments, so as to improve the quality and stability of product, and protect the safety of product in use. Testing electric control reliability needs to build test environment, that is, according to test target and method, various different test environments are built, including high temperature, low temperature, high humidity, low humidity, vibration and the like.
[0003] High-low temperature alternating damp heat chamber is a kind of experimental equipment for simulating different environmental conditions, which is commonly used for testing the performance and reliability of materials, products or systems under different conditions of high temperature, low temperature and humidity. For the test of electric control reliability, this kind of equipment can provide extreme temperature and humidity changes as environmental chamber to evaluate the stability and durability of electric control system under these harsh conditions.
[0004] With more and more new product lines appearing, the samples that need to verify the reliability of electric control are also increasing. Especially during the peak period of the project, due to the need to verify different manufacturers and different schemes, the samples sent by each project team are increasing, which leads to the saturation and overflow of test resources. In the prior art, the problem of too many test resources is generally solved by increasing more environmental equipment for testing. However, purchasing equipment needs more funds and space, and during the off-peak period, the equipment and the space it occupies are wasted. UTILITY MODEL CONTENT
[0005] The utility model solves the technical problem in the prior art by providing an environmental chamber for testing electronic products, which can accommodate multiple samples.
[0006] The utility model solves the technical problem by adopting the following technical scheme: an environmental chamber includes a chamber body, a placement tool is arranged in the chamber body, and the placement tool includes:
[0007] a frame arranged in the chamber body, and a cavity with an open front side and a rear side is formed in the frame;
[0008] a sample holder arranged in the cavity and used for suspending samples.
[0009] In order to facilitate the suspension of samples, preferably, the sample holder includes:
[0010] a support frame arranged on the frame;
[0011] The vertical rods are arranged on the support frame.
[0012] The inner rods are arranged transversely on the vertical rods and are used for hanging the samples.

[0014] Preferably, the vertical rods extend in the vertical direction. The vertical extension of the vertical rods not only utilizes the height space in the cavity but also enables more samples to be hung, and because the inner rods are arranged transversely on the vertical rods, the samples hung on the inner rods are independent of each other, and when a plurality of samples are tested at the same time, the samples do not affect each other. If the vertical rods extend in the horizontal direction, the samples on the upper sample racks are likely to collide with the samples on the lower sample racks, affecting the performance of the samples to be tested and the accuracy of the test.
[0015] In order to facilitate the installation of the sample racks, preferably, the inner wall of the frame is provided with a sliding rail, and the support frame of the sample rack is slidably connected with the frame through the sliding rail.
[0016] Preferably, the frame is grid-shaped. The grid-shaped arrangement facilitates ventilation, does not affect the temperature and humidity inside the box, and maintains the stability of the tooling.
[0017] Preferably, the side wall of the box is provided with a through hole through which the lead wire of the sample passes.
[0018] In order to prevent the sample racks from sliding out from the rear side of the frame, preferably, the rear side of the bottom surface and the rear side of the top surface of the frame are provided with a baffle.
[0019] Preferably, the box is a cube.
[0020] Compared with the prior art, the box of the environmental box is provided with a tooling for placing the tooling, and when the samples are too many, the tooling can be placed for testing. During the off-peak period of sample testing, the tooling can be taken out, and the environmental box can be used as a general test box. In addition, the sample rack can be one or more, a plurality of samples can be hung on one sample rack, and a plurality of sample racks can hang more samples to be tested, which facilitates the simultaneous detection of the electrical control reliability of a plurality of samples.
