Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings.

[0050] This utility model discloses a product testing device 1, see reference 1. Figures 1-5 The product testing device 1 includes a support mechanism 20, a first test chamber 30, a second test chamber 40, and a connecting structure 10.

[0051] The supporting mechanism 20 is used to support the product to be tested; the first test chamber 30 and the second test chamber 40 are arranged adjacent to each other, the first test chamber 30 is used to simulate a first type of environment to test the product to be tested, and the second test chamber 40 is used to simulate a second type of environment to test the product to be tested; the connecting structure 10 is provided between the first test chamber 30 and the second test chamber 40, and is used for the transfer of the supporting mechanism 20 between the first test chamber 30 and the second test chamber 40.

[0052] The first test chamber 30 and the second test chamber 40 can simulate two different test environments. The support mechanism 20 can switch between the first test chamber 30 and the second test chamber 40 through the connecting structure 10. The support mechanism 20 can carry the product to be tested. This support mechanism can be transferred between the first test chamber 30 and the second test chamber 40 through the connecting structure 10. It can perform complex environmental tests on the product by switching between the two test environments provided by the first test chamber 30 and the second test chamber 40, and can provide multiple environmental tests to improve the product functional testing effect.

[0053] Please see Figures 1-2 According to some embodiments of the present invention, optionally, when the supporting mechanism 20 is located in the first test chamber 30 or the second test chamber 40, at least a portion of the supporting mechanism 20 cooperates with the communicating structure 10 to separate the first test chamber 30 and the second test chamber 40.

[0054] In the above scheme, the connecting structure 10 and the supporting mechanism 20 are at least partially matched in size and shape. When the supporting mechanism 20 moves between the first test chamber 30 and the second test chamber 40, the supporting mechanism 20 and the connecting structure 10 cooperate to separate the test environments of the first test chamber 30 and the second test chamber 40, thereby reducing the mutual influence between the test environments of the first test chamber 30 and the second test chamber 40.

[0055] In a specific example, such as Figures 1-2 As shown, the first test chamber 30 is a gaseous environment with a predetermined temperature and humidity, and the second test chamber 40 is a liquid environment with a predetermined temperature. The first test chamber 30 and the second test chamber 40 are arranged adjacent to each other in a vertical direction. The first test chamber 30 is positioned above the second test chamber 40. The vertical arrangement reduces the environmental impact between the first test chamber 30 and the second test chamber 40 (gas and liquid) during environmental switching. Meanwhile, the heavier second test chamber 40 is positioned below to improve the structural stability of the entire device. Of course, in other feasible embodiments, the first test chamber 30 and the second test chamber 40 can also be arranged adjacent to each other in a horizontal direction or other specified directions. Those skilled in the art can set it according to the actual situation, and this application does not limit this.

[0056] Please see Figures 1-2 According to some embodiments of this utility model, optionally, the supporting mechanism 20 includes a first sealing plate 210, a second sealing plate 220, and a supporting plate (not shown in the figure) located between the first sealing plate 210 and the second sealing plate 220 for supporting the product to be tested. When the supporting mechanism 20 is in the first test chamber 30, the second sealing plate 220 and the connecting structure 10 cooperate to separate the test environments of the first test chamber 30 and the second test chamber 40; when the supporting mechanism 20 is in the second test chamber 40, the first sealing plate 210 and the connecting structure 10 cooperate to separate the test environments of the first test chamber 30 and the second test chamber 40.

[0057] In the above scheme, in a specific example, such as Figures 1-2As shown, the first sealing plate 210 and the second sealing plate 220 are shaped to match the connecting structure 10. When the supporting mechanism 20 is in the first test chamber 30, the second sealing plate 220 of the supporting mechanism 20 engages with the connecting structure 10, separating the first test chamber 30 and the second test chamber 40, thereby preventing the second test chamber 40 from interfering with the test environment of the first test chamber 30 and ensuring the stability of the simulation environment within the first test chamber 30. When the supporting mechanism 20 is in the second test chamber 40, the first sealing plate 210 of the supporting mechanism 20 engages with the connecting structure 10, separating the first test chamber 30 and the second test chamber 40, thereby preventing the first test chamber 30 from affecting the test environment of the second test chamber 40 and ensuring the stability of the test environment within the second test chamber 40.

[0058] In a specific example, such as Figure 5 As shown, the support mechanism 20 also includes four support frames 230, which are arranged vertically. A first sealing plate is fixedly connected to the top of the support frame 230, and a second sealing plate is fixedly connected to the bottom of the support frame 230. The outline dimensions of the first and second sealing plates are adapted to the connecting structure 10 to achieve environmental isolation between the first test chamber 30 and the second test chamber 40. Multiple horizontal support ribs 240 are fixed on the four support frames 230 and are arranged opposite to each other. The horizontal support ribs 240 can be staggered in the vertical direction. Multiple horizontal support ribs 240 can be set with multiple support plates to form a multi-layer bearing space for the products under test, so that the products under test can be tested in batches simultaneously, adapting to the testing needs of batch products under test.

[0059] The support plate is mounted on the support frame 230 via horizontal support ribs 240. The two sides of the support plate rest on the horizontal support ribs 240, allowing the product to be tested to be placed on the support mechanism 20. The product then enters the first test chamber 30 or the second test chamber 40 for functional testing. The support plate and support frame 230 can be fixedly connected or detachably connected to improve the flexibility of product handling.

[0060] Please see Figures 1-2 According to some embodiments of the present invention, optionally, the first test chamber 30 and the second test chamber 40 are separated by a partition 110, and the communication structure 10 includes at least a communication port (not shown in the figure) formed on the partition 110.

[0061] like Figures 1-2As shown in the specific embodiment, the connecting structure 10 is a connecting port on the partition 110. The partition 110 can physically separate the first test chamber 30 and the second test chamber 40 in one direction. On the other hand, the connecting port on the partition can realize the rapid switching of the carrying mechanism 20 between the two test chambers. The carrying mechanism 20 can move directly from the first test chamber 30 to the second test chamber 40 through the connecting port on the partition 110. The movement distance is short and the efficiency is high, which can quickly complete the position switching of the product in different test environments.

[0062] The connection port matches the shape and size of the first sealing plate 210 and the second sealing plate 220. When the supporting mechanism 20 is in the first test chamber 30, the second sealing plate 220 is nested with the connection port. When the supporting mechanism 20 is in the second test chamber 40, the first sealing plate 210 is nested with the connection port.

[0063] It should be noted that in other embodiments, the connecting structure 10 may also be a channel or other connecting structure that connects the first test chamber 30 and the second test chamber 40 at both ends respectively. The specific structure of the connecting structure 10 can be set according to actual needs, and this application does not limit it.

[0064] The connecting structure 10 matches the first sealing plate 210 and the second sealing plate 220 to separate the first test chamber 30 and the second test chamber 40. To enable the unobstructed and rapid movement of the carrying mechanism 20 between the first test chamber 30 and the second test chamber 40, the shape and size of the connecting structure 10, the first sealing plate 210, and the second sealing plate 220 are matched to reduce the environmental impact between the two test chambers. Alternatively, in some embodiments, to minimize environmental impact between the two test chambers, sealing structures such as sealing strips can be provided on the carrying mechanism 20 and / or the connecting structure 10 to seal the carrying mechanism 20 during transfer between the first and second test chambers and while it is within the test chamber, thereby reducing the mutual impact between the two test chambers caused by the transfer of the carrying mechanism 20.

[0065] Please see Figures 1-2 According to some embodiments of the present invention, optionally, the product testing device 1 further includes a support mechanism 500 and a driver 530. The support mechanism 500 is fixed to the carrier mechanism 20; the driver 530 is fixedly connected to the support mechanism 500, driving the support mechanism 500 and the carrier mechanism 20 thereon to move so that the carrier mechanism 20 can move to the first test chamber 30 or the second test chamber 40.

[0066] In the above scheme, in such Figure 5 In the specific example shown, the actuator 530 is a cylinder. Of course, in other embodiments, the actuator 530 may also be other feasible actuators.

[0067] The driver 530, fixedly connected to the support mechanism 500, acts as a power source, transmitting displacement driving force to the support mechanism 500 through the movement of its displacement output shaft. This ultimately drives the bearing mechanism 20 to move along a preset path through the connecting structure 10. Figures 1-2 In a specific example, the first test chamber 30 and the second test chamber 40 are arranged vertically adjacent to each other, and the driver 530 drives the support mechanism 500 and the bearing mechanism 20 on the support mechanism to rise and fall along a preset path in the vertical direction.

[0068] Please see Figures 1-2 According to some embodiments of the present invention, optionally, the support mechanism 500 includes a support plate 510 fixedly disposed on the top of the bearing mechanism 20 and a connecting rod 520 fixedly connected in parallel to the displacement output shaft of the driver 530; the first test chamber 30 and the second test chamber 40 are separated by a partition 110, and a guide hole is formed on the partition 110 for the connecting rod 520 and the displacement output shaft to pass through; a positioning hole is formed on one side surface of the support plate 510 corresponding to the displacement output shaft for the insertion and positioning of the displacement output shaft.

[0069] In the above scheme, the first test chamber 30 and the second test chamber 40 are separated by a partition 110, which physically isolates the two chambers. The partition 110 has a guide hole through which the connecting rod 520 and the displacement output shaft pass. The central axis of the guide hole is aligned with the movement trajectory of the connecting rod 520 and maintains a fixed relative position with the connecting structure 10 (the channel through which the carrying mechanism 20 passes), thus limiting the movement direction of the carrying mechanism 20 and ensuring smooth movement without jamming. The guide hole of the partition 110 and the positioning hole of the support plate 510 form a dual positioning system. When the displacement output shaft of the driver 530 is inserted into the positioning hole of the support plate 510, the connecting rod 520 passes through the guide hole parallel to the displacement output shaft, allowing the carrying mechanism 20 to move along a preset path during lifting and lowering, preventing interference between the carrying mechanism 20 and the inner walls or components of the first test chamber 30 and the second test chamber 40 during movement.

[0070] Please see Figures 1-2 According to some embodiments of the present invention, optionally, the first type of environment is a gas environment with a predetermined temperature and humidity, and the first test chamber 30 includes a first test chamber body 300 and a temperature sensor, a humidity sensor, a temperature adjustment component, a humidity adjustment component and an air circulation component 330 corresponding to the first test chamber body 300.

[0071] The temperature regulating component is used to regulate the temperature inside the first test chamber 30; the humidity regulating component is used to generate and deliver water vapor into the first test chamber 30 to regulate the humidity in the first test chamber 30; the air circulation component 330 is used to control the gas circulation in the first test chamber 30.

[0072] In the above scheme, such as Figures 1-2 As shown in the specific embodiment, the temperature sensor can detect the gas temperature inside the first test chamber 300 in real time. The temperature regulation component includes an air heating pipe 310. When the temperature inside the first test chamber 300 is lower than a predetermined temperature, the air inside the first test chamber 300 can be heated by the air heating pipe 310 until the temperature inside the first test chamber 300 reaches the predetermined temperature, at which point the air heating pipe 310 stops heating. The humidity sensor can detect the air humidity inside the first test chamber 300 in real time. When the humidity inside the first test chamber 300 is lower than a predetermined humidity, the humidity regulation component supplies water vapor to the first test chamber 300 to increase the humidity inside the first test chamber 300 until the humidity inside the first test chamber 300 reaches the predetermined humidity.

[0073] It should be noted that the humidity sensor can be a wet-bulb / dry-bulb sensor. The dry-bulb sensor directly measures the ambient temperature, while the wet-bulb sensor (e.g., a thermometer with its sensing end wrapped in damp gauze) measures a lower temperature due to moisture evaporation. The relative humidity inside the first test chamber 300 is calculated using the temperature values ​​detected by the dry-bulb and wet-bulb sensors. In high-temperature and high-humidity test environments, the wet-bulb / dry-bulb sensor provides more stable test results compared to electronic humidity sensors that directly measure humidity through changes in the electrical characteristics of the sensing element, and exhibits stronger tolerance to water vapor present within the first test chamber 300.

[0074] The air circulation assembly 330 includes a circulating fan 331 and an exhaust port 332. The circulating fan 331 is disposed on the top inner wall of the first test chamber 30; the exhaust port 332 is disposed on the top of the first test chamber 30, connecting the first test chamber 30 to the outside of the first test chamber 30. The circulating fan 331 acts on the first test chamber 30, generating a downward airflow when it operates. The airflow flows along the side wall of the first test chamber 30 to the bottom and then flows back, forming an airflow circulation within the first test chamber 300 to simulate real-world airflow changes. The exhaust port 332 can have a built-in electric valve that works in conjunction with a humidity sensor and a temperature sensor to exhaust air. When the humidity inside the first test chamber 300 rises due to excessive water vapor, the valve opens at a certain angle, and the airflow from the circulating fan 331 drives some of the high-humidity air inside the first test chamber 300 to be discharged, quickly restoring the humidity to a predetermined level.

[0075] Please see Figures 1-2 According to some embodiments of this utility model, optionally, the humidity regulating component includes a water vapor generator (not shown in the figure) and a pipe (not shown in the figure). The water vapor generator is disposed outside the first test chamber 300 and can generate water vapor; the pipe connects the water vapor generator and the first test chamber 300, and transports the water vapor generated by the water vapor generator into the first test chamber 300.

[0076] In the above scheme, the steam generator converts electrical energy into heat energy to heat the water in its tank, causing the water to boil and produce saturated steam, which is then transported to the first test chamber 300 through a pipeline. When the humidity inside the first test chamber 300 is lower than a predetermined humidity, the steam generator operates to produce steam. After the steam is transported to the first test chamber 300 through the pipeline, the humidity inside the first test chamber 300 gradually increases until it reaches the target predetermined humidity. At this point, the steam generator stops operating, thereby achieving humidity control within the first test chamber 300.

[0077] Optionally, a drip outlet (not shown in the figure) may be provided at the bottom of the first test chamber 300. Water vapor in the first test chamber easily condenses into liquid water, and this condensed liquid water can be discharged through the drip outlet to prevent water accumulation.

[0078] like Figures 1-2 As shown, when the first test chamber 30 forms a test environment with a predetermined temperature and humidity, the steam generator supplies water vapor into the first test chamber 300. The circulating fan 331 quickly mixes the water vapor with the air inside the chamber, adjusting the humidity within the first test chamber 300 and improving the uniformity of the ambient humidity. If the humidity exceeds the set value, the exhaust port 332 opens, quickly stabilizing the humidity at the predetermined level by discharging the mixed, high-humidity air. When the temperature regulation component operates and heats up, the circulating fan 331 drives the airflow through the air heating pipe 310, causing the high-temperature gas to quickly diffuse to all areas within the first test chamber 300, thereby avoiding localized temperature differences.

[0079] Please see Figures 1-2 According to some embodiments of the present invention, optionally, the second type of environment is a liquid environment at a predetermined temperature, and the second test chamber 40 includes a second test chamber body 400 and a temperature measuring and control component, a heating component 420, a liquid cooling circulation component, a drain valve 440 and a water inlet valve provided corresponding to the second test chamber body 400 for measuring the liquid temperature inside the second test chamber body 400.

[0080] The heating component 420 is used to raise the temperature of the liquid in the second test chamber 400; the liquid cooling circulation component is used to cool the liquid output from the second test chamber 400 and then return it to the second test chamber 400; the drain valve 440 is used to discharge the liquid in the second test chamber 400; and the water inlet valve is used to replenish the liquid in the second test chamber 400.

[0081] like Figures 1-2 As shown, when liquid needs to be added to the second test chamber 400, the inlet valve opens, injecting liquid to the set level. When the temperature inside the second test chamber 400 is lower than the predetermined temperature, the heating component 420 heats the liquid inside the second test chamber 400 until the predetermined temperature is reached. When the liquid temperature inside the second test chamber 400 exceeds the predetermined temperature, the heating component 420 shuts off, and the liquid cooling circulation component lowers the liquid temperature in the second test chamber 400 to the predetermined temperature through a refrigeration cycle, while the circulation function drives liquid flow. After the test is completed, the drain valve 440 can be opened to drain the liquid from the second test chamber 400.

[0082] In a specific example, the temperature measurement and control component is a dual-output temperature controller, which performs detection through the temperature measurement port 410 set in the wall of the second test chamber 400, so as to achieve the purpose of detecting the liquid temperature at the temperature measurement port 410.

[0083] It should be noted that the liquid cooling circulation assembly maintains dynamic circulation of the liquid within the second test chamber 400. The liquid cooling circulation assembly may have a built-in circulation pump to promote liquid circulation. Optionally, the liquid cooling circulation assembly can be continuously activated to promote temperature uniformity of the liquid within the second test chamber 400. When the heating assembly 420 is operating, the circulation rapidly carries the high-temperature liquid near the heating tube to the entire second test chamber 400, preventing overheating in localized areas of the heating assembly while the rest of the chamber remains below the predetermined temperature. When the cooling function of the liquid cooling circulation assembly is activated, the low-temperature liquid cooled by the liquid cooling circulation assembly diffuses through circulation, fully mixing with the high-temperature liquid within the second test chamber 400, preventing localized overcooling in the liquid cooling circulation assembly while the rest of the chamber remains above the preset temperature. The circulation of the liquid cooling circulation assembly, in conjunction with temperature changes within the second test chamber 400, ensures uniform liquid temperature within the second test chamber 400.

[0084] like Figure 1 In the specific embodiment shown, the temperature measuring port 410 of the second test chamber 400 is located in the middle area between the water inlet pipe 432 and the water outlet pipe 433 of the liquid cooling circulation component. This avoids inaccurate detection due to local heating or cooling and ensures that the dual-output temperature controller detects the average temperature of the liquid inside the second test chamber 400 through the temperature measuring port 410.

[0085] Please see Figures 1-2According to some embodiments of the present invention, optionally, the liquid cooling circulation assembly includes a chiller 431, an outlet pipe 433, and an inlet pipe 432. The chiller 431 is disposed outside the second test chamber 400 and is used to cool the input liquid. The outlet pipe 433 connects the chiller and the second test chamber 400, and transports the liquid in the second test chamber 400 to the chiller 431. The inlet pipe 432 connects the chiller 431 and the second test chamber 400, and transports the liquid cooled by the chiller 431 back into the second test chamber 400.

[0086] In the above scheme, when the liquid temperature in the second test chamber 400 is higher than the target value, the chiller 431 starts the cooling function, which quickly reduces the temperature of the liquid in the second test chamber 400 output from the outlet pipe 433 to the predetermined temperature and then transports it back to the second test chamber 400 through the inlet pipe 432.

[0087] It should be noted that, as Figure 3 As shown, the water outlet pipe 433 is located at the bottom of the wall of the second test chamber 400, and the water inlet pipe 432 is located at the top of the wall of the second test chamber 400. The positions of the water outlet pipe 433 and the water inlet pipe 432 are designed to utilize gravity to assist the liquid flow out and cooperate with circulation.

[0088] In addition, such as Figure 4 The product testing device 1 is equipped with a cooling fan 100 on its outer wall. The cooling fan 100 accelerates the air convection between the inside of the product testing device 1 and the external environment, and promptly removes the excess heat generated during the operation of the product testing device 1, so as to maintain the overall operating temperature of the product testing device 1 stable.
