[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] In the production of electronic components, to ensure product quality, it is necessary to guarantee that the electronic components can function normally under low or high voltage and low or high temperature environments. Related technologies utilize environmental simulation test chambers, where electronic components are placed in environments with low or normal pressure and low or high temperatures. However, existing environmental simulation test chambers are only suitable for testing small electronic components and cannot be used for testing larger electronic components in large equipment, such as energy storage containers.

[0049] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment provides an environmental simulation test device. The environmental simulation test device includes a foundation 300, a pressure chamber 100, a temperature regulating chamber 200, a temperature regulating mechanism 500, and a pressure regulating mechanism. The foundation 300 is fixed to the ground and is configured to support the pressure chamber 100. The pressure chamber 100 has a pressure-bearing cavity 110 that can be isolated from the outside environment. The temperature regulating chamber 200 is housed within the pressure-bearing cavity 110 and has a temperature regulating cavity 210 that is connected to the pressure-bearing cavity 110. The temperature regulating cavity 210 is used to contain a product 2000. The temperature regulating mechanism 500 is configured to regulate the temperature of the temperature regulating cavity 210, and the pressure regulating mechanism is configured to regulate the pressure of the temperature regulating cavity 210.

[0050] This environmental simulation test device features a pressure chamber 110 within the pressure chamber 100, which is isolated from the outside environment. A temperature-regulating chamber 200 is placed within the pressure chamber 110, and the product 2000 is housed within a temperature-regulating chamber 210 within the temperature-regulating chamber 200. The temperature-regulating chamber 210 is connected to the pressure chamber 110. A pressure regulating mechanism adjusts the pressure of the temperature-regulating chamber 210, and a temperature regulating mechanism 500 adjusts the temperature of the temperature-regulating chamber 210. This allows for realistic simulation of low-temperature, high-temperature, low-pressure, and normal-pressure environments, ensuring effective testing of the product 2000. Furthermore, the connection between the temperature-regulating chamber 210 and the pressure chamber 110 ensures consistent pressure inside and outside the temperature-regulating chamber 200, enhancing its protection. The additional support provided by a foundation 300 fixed to the ground further strengthens the pressure chamber 100, improving the structural strength of the environmental simulation test device and meeting the testing requirements of large equipment.

[0051] It should be noted that in this embodiment, the temperature regulating chamber 200 has four balancing through holes to enable communication between the temperature regulating cavity 210 and the pressure-bearing cavity 110. In other embodiments, the specific number of balancing through holes can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0052] As an optional solution, the foundation 300 includes a pit 310 and a supporting column 320. The supporting column 320 extends vertically and is fixed within the pit 310, and is configured to support the pressure chamber 100. By setting the pit 310 within the foundation 300 and installing the supporting column 320 within the pit 310, the pressure chamber 100 is supported by the supporting column 320. This not only achieves stable support for the pressure chamber 100 but also reduces the support height of the pressure chamber 100, lowers the center of gravity of the pressure chamber 100, and further improves the structural stability of the environmental simulation test device.

[0053] Optionally, the depth of the foundation pit 310 is not less than 2 meters, and a ladder 330 is provided on the side wall of the foundation pit 310. By ensuring that the depth of the foundation pit 310 is not less than 2 meters, it is possible to ensure that the foundation 300 has a sufficiently large size and ensure the structural strength of the foundation 300. By providing a ladder 330 on the side wall of the foundation pit 310, it is possible to facilitate the subsequent entry and exit of workers from the foundation pit 310.

[0054] To further improve the support effect on the pressure chamber 100, the foundation 300 includes multiple support columns 320, which are spaced apart within the foundation pit 310 and jointly support the pressure chamber 100. It should be noted that in this embodiment, the foundation 300 includes 16 support columns 320, which are spaced apart within the foundation pit 310 and jointly support the pressure chamber 100. In other embodiments, the specific number of support columns 320 can be adaptively adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0055] Furthermore, to ensure the fixing effect and accuracy between the support column 320 and the pressure chamber 100, the support column 320 and the pressure chamber 100 are fixedly connected by secondary grouting. The secondary grouting fixing method is existing technology and will not be described in detail here.

[0056] As an optional solution, the walls of the temperature-regulating chamber 200 include an outer panel, an inner panel, and an insulation layer. The outer panel has a thickness of not less than 10mm, the inner panel has a thickness of not less than 10mm, and the insulation layer is sandwiched between the outer and inner panels, with a thickness of not less than 100mm. By configuring the walls of the temperature-regulating chamber 200 as an inner panel, insulation layer, and outer panel stacked sequentially from the inside out, ensuring that the thickness of both the inner and outer panels is not less than 10mm and the thickness of the insulation layer is not less than 100mm, the structural strength of the temperature-regulating chamber 200 can be guaranteed while ensuring good insulation performance. It should be noted that in this embodiment, both the outer and inner panels are steel plates, and the insulation layer is polyurethane foam. The thickness of both the outer and inner panels is 12mm, and the thickness of the insulation layer is 120mm. In other embodiments, other rigid materials can be selected to manufacture the outer and inner panels, and other insulation materials can be selected to manufacture the insulation layer. The thickness of the outer and inner panels and the thickness of the insulation layer can be adjusted within a range of not less than 10 mm and within a range of not less than 100 mm, respectively, according to actual needs. This embodiment does not impose specific limitations.

[0057] Furthermore, in this embodiment, the structure of the pressure chamber 100 is basically the same as that of the temperature regulating chamber 200. The only difference is that the pressure chamber 100 does not have an insulation layer. To keep the text concise, the structure of the pressure chamber 100 will not be described in detail here.

[0058] As an optional feature, the pressure chamber 100 is equipped with an electric sliding door. The electric sliding door is equipped with a sealing strip, a limit protection structure, and an anti-collision structure to ensure the isolation effect between the pressure chamber 110 and the outside world while improving the protection of the electric sliding door.

[0059] In one optional embodiment, the temperature regulating mechanism 500 includes at least one set of temperature regulating components. Each temperature regulating component includes two sets of temperature regulating structures, which are symmetrically arranged about the central axis of the temperature regulating cavity 210 in the vertical direction. Each set of temperature regulating structures can generate hot or cold air circulating within the temperature regulating cavity 210, and the hot or cold air generated by the two sets of temperature regulating structures is blown towards the product 2000 from opposite ends. By providing at least one set of temperature regulating components within the temperature regulating mechanism 500, and symmetrically arranging the two sets of temperature regulating structures relative to the central axis of the temperature regulating cavity 210 in the vertical direction, and blowing the cold or hot air generated by the two sets of temperature regulating structures towards the product 2000 from opposite ends, the heating or cooling efficiency of the product 2000 can be improved. It should be noted that in this embodiment, the temperature regulating mechanism 500 includes one set of temperature regulating components. In other embodiments, the specific number of temperature regulating components can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0060] Combination Figure 2The specific structure of the temperature regulation structure is described below. Each temperature regulation structure includes a fan 510, a heating element 520, and a cooling element 530. The fan 510 is located at the upper end of the temperature regulation cavity 210 and at one end of the vertical center of the temperature regulation cavity 210. The heating element 520 is located at the upper end of the temperature regulation cavity 210 and between the fan 510 and the vertical central axis of the temperature regulation cavity 210. The heating element 520 can generate heat. The cooling element 530 is located at the upper end of the temperature regulation cavity 210 and between the heating element 520 and the vertical central axis of the temperature regulation cavity 210. The heating element 520 can cool. The fan 510 can drive the air in the temperature regulation cavity 210 to pass through the cooling element 530 and the heating element 520 in sequence and then flow along the side wall and bottom wall of the temperature regulation cavity 210 in sequence, so that hot or cold air is blown towards the product 2000 set on the bottom wall.

[0061] When product 2000 needs to be cooled, the cooling components 530 and fans 510 in the two sets of temperature regulation structures are activated respectively. The fans 510 drive air through the cooling components 530, which cool the air, causing it to flow along the side and bottom walls of the temperature regulation cavity 210 and blow it onto product 2000, thus cooling product 2000. When product 2000 needs to be heated, the heating components 520 and fans 510 in the two sets of temperature regulation structures are activated respectively. The fans 510 drive air through the heating components 520, which cool the air, causing it to flow along the side and bottom walls of the temperature regulation cavity 210 and blow it onto product 2000, thus heating product 2000. It should be noted that the heating components 520 and cooling components 530 are existing technologies and will not be described in detail here.

[0062] When the refrigeration unit 530 is operating, condensation is easily generated. To prevent this condensation from contacting the product 2000, the refrigeration unit 530 has a first guide pipe. A water tank is installed inside the pressure chamber 110. The first guide pipe is equipped with a first solenoid valve. One end of the first guide pipe is connected to the refrigeration unit 530, and the other end is connected to the water tank. The first solenoid valve controls the opening and closing of the first guide pipe, allowing the condensation generated by the refrigeration unit 530 to be directly discharged into the water tank along the first guide pipe. The water tank is also equipped with a second guide pipe, which is equipped with a second solenoid valve. One end of the second guide pipe is connected to the water tank, and the other end is open to the outside. The second solenoid valve controls the opening and closing of the second guide pipe. When the water tank is full of condensation, the second solenoid valve opens to open the second guide pipe, allowing the condensation in the water tank to be discharged to the outside. It should be noted that, in this embodiment, the other end of the second diversion pipe is located in the foundation pit 310 of the foundation 300, and the foundation pit 310 is provided with an annular drainage groove to discharge the condensate water discharged along the second diversion pipe from the foundation pit 310.

[0063] In an optional embodiment, the environmental simulation testing apparatus further includes a support frame 400, which is disposed within the temperature-regulating cavity 210 and configured to support the product 2000. By placing the product 2000 on the support frame 400 within the temperature-regulating cavity 210, the product 2000 is isolated from the cavity wall of the temperature-regulating cavity 210, preventing collisions between the product 2000 and the cavity wall during product transfer, thus improving the protection of both the temperature-regulating cavity 210 and the product 2000. It should be noted that in this embodiment, the support frame 400 is made of steel plate to ensure sufficient strength for stably supporting the product 2000.

[0064] As an optional solution, the environmental simulation test apparatus also includes an equipment compartment, located outside the pressure chamber 100. The output ends of both the temperature regulation mechanism 500 and the pressure regulation mechanism are located within the temperature control cavity 210. The main bodies of both the temperature regulation mechanism 500 and the pressure regulation mechanism are housed within the equipment compartment and connected to their respective output ends via wiring harnesses and conduits. By additionally setting up an equipment compartment outside the pressure chamber 100, and placing the main bodies of the temperature regulation mechanism 500 and the pressure regulation mechanism within it, and connecting the output ends of the temperature regulation mechanism 500 and the pressure regulation mechanism to their respective main bodies using wiring harnesses and conduits, the main bodies of the temperature regulation mechanism 500 and the pressure regulation mechanism do not occupy space in the temperature control cavity 210, thus improving the space utilization of the temperature control cavity 210.

[0065] It should be noted that in this embodiment, the pressure regulating mechanism is a vacuum mechanism, the vacuum pump of the vacuum mechanism is stored in the equipment compartment, and the heat exchange structure inside the temperature regulating mechanism 500 is stored in the equipment compartment.

[0066] Understandably, to meet the requirements of connecting the main body of the temperature regulating mechanism 500 to its output end and the main body of the pressure regulating mechanism to its output end using wiring harnesses and pipes, it is necessary for the wiring harnesses and pipes to pass through the pressure chamber 100. Therefore, the pressure chamber 100 is provided with through holes for the wiring harnesses and pipes to pass through. The pressure chamber 100 also includes a sealing structure configured to seal the gaps between the wiring harness and the through holes, as well as the gaps between the pipes and the through holes. By using the sealing structure to seal the gaps between the wiring harness and the through holes, as well as the gaps between the pipes and the through holes, the isolation effect between the pressure chamber 110 inside the pressure chamber 100 and the outside environment can be ensured. It should be noted that the specific structure of the sealing structure is prior art and will not be described in detail here.

[0067] To facilitate subsequent inspection and maintenance of the sealing structure, a folding tray is provided on the outside of the pressure chamber 100. The folding tray is located below the through hole. When the sealing structure is repaired or replaced, the folding tray can be opened and the disassembly and assembly tools can be placed on the folding tray, thereby improving work efficiency.

[0068] Optionally, the environmental simulation test apparatus also includes a humidity control mechanism configured to regulate the humidity of the temperature control chamber 210. By additionally equipping the humidity control mechanism to adjust the humidity of the temperature control chamber 210, environments with different humidity levels can be realistically simulated, thereby further improving the testing effect on product 2000. It should be noted that the specific structure and working principle of the humidity control mechanism are existing technologies and will not be described in detail here.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
