Abstract
Description
Technical Field
[0001] This utility model relates to the field of test chamber technology, specifically a temperature, humidity and vibration integrated test chamber. Background Technology
[0002] In industrial production and product development, various electronic components, mechanical parts, and complete products often face the challenges of complex environments such as high temperature, high humidity, and vibration during actual use, transportation, or storage. These environmental factors can lead to performance degradation, structural failure, or even product scrapping. Therefore, it is crucial to conduct reliability tests in test chambers to simulate extreme environments before products are put on the market. The purpose is to assess the product's ability to withstand harsh conditions, identify design flaws and potential failures in advance, and ensure the product's safety and lifespan. Currently, environmental test chambers on the market have relatively limited functions, with most only able to simulate a single environment.
[0003] A search revealed that application number CN202122322775.9 discloses a vibration component for a combined humidity and temperature vibration test chamber. This component includes a vibration placement plate with a multi-directional vibration mechanism at its bottom. The multi-directional vibration mechanism includes a connecting block with a vibration rod connected to its bottom. A vertical vibration cylinder is mounted on the bottom of the vibration rod. This device, through its multi-directional vibration mechanism, allows the lateral vibration block to drive the connecting plate, causing the connecting ring to vibrate laterally. Simultaneously, the longitudinal vibration ring compresses the longitudinal vibration spring, achieving longitudinal vibration. This multi-directional vibration provides more test data, improves applicability, and maintains stable vibration operation during operation, preventing damage or deformation of the springs, thus enhancing durability and practicality.
[0004] However, when using the above-mentioned equipment, the test specimen is fixed by a cylinder. In high temperature and high humidity environments, it is prone to failure due to component corrosion and circuit aging, resulting in poor stability. At the same time, the vibration table is equipped with fixing parts on all four sides, and the test specimen needs to be lifted and placed from above the vibration table. Especially for large and heavy test specimens, the loading and unloading process is laborious and the test specimen is prone to falling and the equipment may be damaged due to unstable operation, which poses safety hazards and inconvenience to operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] This invention, by setting up a test chamber that integrates three environmental simulation functions—high temperature, high humidity, and vibration—enables flexible testing of a single environment, dual combined environments, and triple synchronous environments using a single device. It eliminates the need to transfer test samples between multiple devices, reducing operating costs and time, minimizing interference from multiple transfers on the test status, and improving testing efficiency and versatility. It can meet the reliability verification needs of different products in various complex environments.
[0022] This invention, by setting up a synchronous fixing component and using a mechanical structure, prevents circuit aging due to high temperature and avoids corrosion of pneumatic components or blockage of air passages due to high humidity in extreme environments of high temperature and high humidity. It significantly reduces the impact of the environment, lowers the probability of equipment failure, and ensures stable fixing performance during long-term testing.
[0023] This invention allows the test specimen to be gently pushed onto the platform from the front by opening the front of the vibration table while limiting the rear and left and right sides, without having to lift it from above. This is especially useful for large and heavy test specimens, avoiding problems such as test specimens falling or equipment collisions caused by unstable lifting and placing, thus improving the convenience of loading and unloading and the safety of operation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1:
[0034] Please see Figures 1 to 3 This utility model provides a technical solution:
[0035] A temperature, humidity, and vibration integrated test chamber is used to conduct high-temperature, high-humidity, and severe vibration simulation tests on test samples, including:
[0036] The test chamber has a test area at the front end and a humidifier installed at the rear end 101. A partition 104 is provided in the middle of the test area. A base 2 is fixedly connected to the lower area of the partition 104 by expansion screws. The partition 104 has an opening in the center. The upper surface of the base 2 is connected to a vibration table 3. The vibration table 3 passes through the opening and reaches above the partition 104.
[0037] The partition 104 is preferably made of a composite material consisting of a stainless steel frame with embedded glass fiber reinforced phenolic resin board. This material has good high temperature resistance, low moisture absorption, and structural strength. The partition 104 physically separates the base 2 of the vibration table 3, placing it completely in an independent space below the partition 104. This prevents the high temperature and high humidity environment of the test area above the partition 104 from directly affecting the base 2, reducing the impact of the test on the base 2. High temperature can cause thermal expansion and deformation of the metal parts of the base 2, affecting the vibration accuracy, while high humidity may cause corrosion of the motor and transmission mechanism of the base 2 or a decrease in insulation performance. The partition 104 can block most of the heat conduction and most of the moisture penetration, providing a dry and normal temperature working environment for the base 2, ensuring the stability and service life of the vibration table 3 drive system.
[0038] A heating element 5 is fixedly connected to the rear end face of the test area inside the test chamber. A nozzle fixing hole 601 is also provided on the rear end face of the test area. A humidifying nozzle 6 is fixedly connected in the nozzle fixing hole 601. The humidifying nozzle 6 is connected to a humidifier.
[0039] Specifically, the partition 104 between the test area and the test chamber body is preferably made of stainless steel frame composite high-temperature resistant insulation board. The stainless steel frame provides structural support (to resist stress caused by vibration), and the thermal conductivity of the aluminum silicate fiber insulation layer inside is ≤0.12W / (m·K). This avoids the high temperature and high humidity environment of the test area from affecting the downstream components (such as the control system and humidifier) and ensures physical isolation between the test area and other areas of the test chamber.
[0040] The control system preferably uses a Siemens S7-1500 series PLC as its core. The humidifier adopts an ultrasonic atomizing type (US-100 model is preferred) and is connected to the PLC digital output module through a solenoid valve. For high-temperature environment control, a PT100 platinum resistance sensor and a nickel-chromium alloy heating tube are preferred, and for high-humidity environment control, a capacitive humidity sensor is preferred. Both are controlled through the PLC analog input module, or components that meet the requirements of composite environment testing can be selected according to the testing needs.
[0041] The vibration table 3 is equipped with a fixing component for quickly fixing the test specimen.
[0042] Specifically, the vibration table 3 is preferably an electromagnetic vibration table 3, such as the EM-100 model, which can cover multiple vibration modes such as sinusoidal and random. The vibration table 3 is equipped with a fixing component to ensure that the test specimen is rigidly connected to the vibration table 3, so that the vibration energy generated by the vibration table 3 can be completely transferred to the test specimen, realistically simulating its stress state under vibration. At the same time, it avoids the test specimen from being displaced or colliding during vibration, which could lead to distorted test data, or from falling off and causing equipment damage and safety hazards. Existing technologies often use pneumatic or manual clamps for clamping and strapping (using high-strength nylon straps in conjunction with table hooks for fixing), and the fixing methods will not be described in detail here.
[0043] Specifically, the door 102 of the integrated test chamber 1 has a manhole 105, and the rear end 101 of the test chamber has a heat dissipation vent 103 on the side.
[0044] In this embodiment, the operator first opens the test area through the chamber door 102, places the test sample on the vibration table 3, and fixes it using the fixing components. After closing the chamber door 102, the operator sets the target high temperature value, target humidity value, vibration parameters, test duration, and number of cycles through the control system. During the test, the operator can observe the status of the test sample through the manhole 105, and the heat dissipation vent 103 at the rear end promptly dissipates the heat generated by the equipment operation. After the set duration or number of cycles is reached, the equipment automatically stops. After the test area returns to normal temperature, the operator opens the chamber door 102 to remove the test sample, completing the test.
[0045] In this embodiment, the test chamber integrates simulations of three extreme environments. Compared with existing test chambers with single functions, it can cover a wider range of test environments. It can conduct high temperature, high humidity, or vibration tests individually, or it can be flexibly combined into dual environment tests such as temperature and humidity, temperature and vibration, and humidity and vibration. Furthermore, it can achieve triple synchronous testing of high temperature, high humidity, and vibration, meeting the diverse testing needs of different products. It reduces the time and operating costs of transferring test samples between different devices, avoids interference with the test status from multiple transfers, improves test efficiency and data accuracy, and locates the causes of product performance defects through multiple combined tests.
[0046] Example 2:
[0047] Please see Figures 4 to 7 This utility model provides a technical solution:
[0048] The vibration table 3 is equipped with a synchronous fixing component 4 for quickly fixing the test specimen.
[0049] Specifically, such as Figure 4The synchronous fixing assembly 4 includes a first fixing plate 401 and a second fixing plate 402. The rear end of the first fixing plate 401 is fixedly connected to both sides of the lower end face of the vibration table 3. The front end of the first fixing plate 401 extends to the upper side of the vibration table 3. A first guide rod 403 is fixedly connected between the two first fixing plates 401. The second fixing plate 402 is fixedly connected to the lower end face of the front end of the vibration table 3. A second guide rod 404 is fixedly connected between the second fixing plates 402. A fixed slide bar 405 is slidably connected to the second guide rod 404. The other end of the fixed slide bar 405 is slidably connected to the first guide rod 403.
[0050] In this embodiment, the first guide rod 403 is located above the vibration table 3, and the second guide rod 404 is located below the vibration table 3. The fixed slide 405 connecting the two, together with the first fixed plate 401 and the second fixed plate 402, forms obstructions at the rear, left, and right sides of the vibration table 3, while leaving the front open (e.g., ...). Figure 4 In the prior art, since the fixing components (such as clamps and clamping plates) are set above the vibration table 3, when the test specimen is placed, it is lifted from above the table. When the test specimen is large or heavy, it is easy to lose control and fall, which may directly damage the fixing clamps and table of the vibration table 3. However, this solution has limiting at the rear and left and right sides of the vibration table 3, while the front is completely open, so that the test specimen is pushed smoothly from the front to the table of the vibration table 3 without damaging the fixing structure due to bumps.
[0051] Specifically, a fixing ring 406 is fixedly connected to the rear end of the fixing slide bar 405, and a rear fixing plate 407 is fixedly connected to the side of the fixing ring 406.
[0052] The rear end of the fixed slide bar 405 is slidably connected to the first guide rod 403, which constrains the forward and backward movement trajectory of the fixed slide bar 405. When the test specimen is pushed in from the front, the fixing ring 406, which is fixed to the fixed slide bar 405 by bolts, and the rear fixing plate 407 are engaged with the edge of the test specimen. Even if the test specimen is subjected to a backward force during vibration, it will not be able to move backward due to the limitation of the rear fixing plate 407, making the position of the test specimen on the vibration table 3 more stable and enhancing the fixation stability between the test specimen and the vibration table 3.
[0053] Specifically, the upper front end face of the fixed slide bar 405 is provided with a straight slide groove 410, the straight slide groove 410 is engaged with the sliding ring 408, and the side of the sliding ring 408 is fixedly connected with a front moving plate 409.
[0054] Both sides of the fixed slider 405 have straight grooves 410 on their upper surfaces (e.g., Figure 4The upper surfaces of the fixed sliding strips 405 on both sides are provided with straight sliding grooves 410. The sliding ring 408 can move flexibly back and forth within the straight sliding grooves 410. During its movement, it will simultaneously drive the front moving plate 409 fixedly connected to the side to move together. When the sliding ring 408 slides forward along the straight sliding grooves 410, the front moving plate 409 expands the placement space forward accordingly; when it slides backward, the front moving plate 409 moves backward to reduce the placement space. With the rear fixed plate 407 connected to the fixed ring 406 at the rear end, the distance between the front and rear fixed plates 407 can be flexibly adjusted, thereby changing the size of the area for fixing the test specimen, which can adapt to the fixing requirements of test specimens of different sizes and specifications.
[0055] Specifically, the fixed slide bar 405 has a first side slide groove 411 and a second side slide groove 412 on its side, and the first side slide groove 411 and the second side slide groove 412 are located inside the fixed slide bar 405 and communicate with each other.
[0056] Specifically, a first fixing bolt 415 is provided on the side of the sliding ring 408 for fixing the sliding ring 408. The first fixing bolt 415 passes through the sliding ring 408 and reaches into the first side groove 411.
[0057] Specifically, a clamping plate 414 is threaded onto the first fixing bolt 415, and the right side of the clamping plate 414 is slidably connected within the second side groove 412 (e.g., Figure 6 The threaded end of the first fixing bolt 415 is slidably connected in the first side groove 411.
[0058] Specifically, a nut 413 is provided on the first fixing bolt 415 to cooperate with the clamping plate 414 and the first fixing bolt 415 to fix the sliding ring 408. The clamping plate 414 and the first fixing bolt 415 are threadedly engaged.
[0059] Specifically, the test sample can be pre-loaded into a rectangular box of suitable size. The box has regular edges and a certain degree of rigidity, which can form a stable fit with the front moving plate 409 and the rear fixing plate 407 of the synchronous fixing component 4, so that the overall outline of the test sample is uniform, avoiding the problem of unstable clamping caused by the irregular shape of the test sample itself, and allowing the plate to apply clamping force more evenly.
[0060] In this embodiment, when the first fixing bolt 415 and the clamping plate 414 move with the sliding ring 408, the first side slide groove 411 provides sliding space for the first fixing bolt 415, and the second side slide groove 412 provides a corresponding sliding path for the clamping plate 414. The clamping plate 414 is C-shaped, with one half of its structure located at the connection between the first side slide groove 411 and the second side slide groove 412. After the test sample is pushed into place and the forward moving plate 409 is adjusted to the appropriate position, the operator tightens the first fixing bolt 415. The threaded end of the bolt is subjected to force in the first side groove 411, which drives the "C" shaped clamp 414 to retract inward. The clamp 414 tightly clamps the inner wall of the side groove of the fixed slide bar 405, thereby firmly fixing the sliding ring 408 in the current position. The nut 413 on the first fixing bolt 415 can be further tightened to prevent the bolt from loosening and coming off during vibration. This ensures that the clamping state formed by the cooperation of the front moving clamp 409 and the rear fixed clamp 407 is stable and reliable, and ensures that the test specimen does not shift during vibration testing.
[0061] In this embodiment, the lower end face of the second guide rod 404 is provided with multiple guide rod through holes 416, and the lower end face of the front end of the fixed slide bar 405 is provided with a threaded hole. The threaded hole of the fixed slide bar is threaded with a second fixing bolt 417. The second fixing bolt 417 passes through the threaded hole and the guide rod through hole 416 on the second guide rod 404, and reaches the threaded hole on the other side, thereby fixing the fixed slide bar 405 on the guide rod, thereby limiting the left and right displacement of the fixed slide bar. With the first fixing bolt 415 and the clamping plate 414, the fixed slide bar 405 and the front moving clamping plate 409 connected to it can be rigidly constrained from the front, back, left and right directions. Combined with the rear fixing clamping plate 407 limiting the rear end of the test specimen, the displacement trend that the test specimen may generate during vibration can be comprehensively limited, thereby improving the stability and reliability of vibration testing.
[0062] In this embodiment, the synchronous fixing component 4 is a purely mechanical structure. The entire fixing process is completed only through the cooperation of mechanical parts such as guide rods, slide bars, bolts, clamping plates 414, and card plates. No pneumatic or electric components such as cylinders or solenoid valves are used. It does not rely on circuit or air circuit drive. In the extreme environment of high temperature and high humidity in the test area, it will not cause circuit aging or component performance degradation due to high temperature, nor will it cause problems such as corrosion of pneumatic components or air circuit blockage due to high humidity. The influence of environmental factors is significantly reduced, and it can maintain stable fixing performance in long-term complex environment testing, reducing the probability of equipment failure.
[0063] Furthermore, compared to the existing technology that uses straps and elastic bands for fixing, the synchronous fixing component 4 provides more stable fixing. The restraining force of straps and elastic bands is greatly affected by the elasticity of the material and the degree of tension. During vibration, they are prone to loosening due to continuous stress, which can cause the test specimen to shift, shake, or even fall off the table.
[0064] In use, the operator first opens the test chamber door 102, pushes the test sample into the vibration table 3 from the front opening, adjusts the distance between the two sides by sliding the fixed slide bar 405 according to the size of the test sample, then moves the front moving plate 409 to cooperate with the rear fixed plate 407 to clamp the test sample, then tightens the first fixing bolt 415 to drive the clamping plate 414 to lock the sliding ring 408, and tightens the second fixing bolt 417 to fix the slide bar 405 to the left and right positions, thus completing the fixation of the test sample; after closing the chamber door 102, the operator selects the single, dual or triple environment test mode and sets the parameters through the control system, starts the equipment, and the heating, humidification and vibration systems operate according to the settings. During the test, the status can be observed through the manhole 105. After the test is completed and the equipment has cooled down, the operator opens the chamber door 102, loosens the bolts and removes the test sample, thus completing the entire test process.
[0065] All other parts of this utility model not described herein are the same as existing technology, or are known technology, or can be implemented using existing technology, and will not be described in detail here.
[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
