[0049] Climate environment simulation test chambers can simulate a variety of climate and environmental conditions in nature, and are often used to test the performance and functions of precision electronic components under various environmental conditions. During the test, it is necessary to connect the relevant interfaces or adjust the parameters of the precision electronic components placed in the climate environment simulation test chamber. Traditional climate environment simulation test chambers require the door to be opened for operation. This operation process often causes drastic changes and fluctuations in the environmental conditions in the climate environment simulation test chamber, and causes external dust to enter the climate environment simulation test chamber, resulting in unreliable test results or test failure.

[0050] To solve the above problems, Figure 1-Figure 7 As shown, the present embodiment provides a climate environment simulation test box, which includes a test chamber 1, the test chamber 1 has a accommodating cavity 112, the test chamber 1 includes a box body 11, an inner door assembly 12 and an outer door assembly 14, the box body 11 has a connected accommodating cavity 112 and an opening 111, the inner door assembly 12 can block or open the opening 111, the inner door assembly 12 is provided with an operating window 13, the operating window 13 can connect or isolate the accommodating cavity 112 from the external environment, and the outer door assembly 14 can be sealed and covered on the inner door assembly 12 and the box body 11.

[0051] When using this climate environment simulation test box for testing, the inner door assembly 12 and the outer door assembly 14 are both in the open state, and the precision electronic components can be placed in the accommodating cavity 112 of the test chamber 1, and then the inner door assembly 12 is closed so that the inner door assembly 12 blocks the opening 111, and the outer door assembly 14 is closed so that the sealing cover of the outer door assembly 14 is arranged on the inner door assembly 12 and the box body 11, so as to ensure the good airtightness of the test chamber 1; when it is necessary to connect the relevant interfaces or adjust the parameters of the precision electronic components during the test process, the outer door assembly 14 is opened, and the operator can reach into the accommodating cavity 112 of the test chamber 1 through the operation window 13 to perform the operation.

[0052] By setting up a double-door structure of the inner door assembly 12 and the outer door assembly 14, operations can be performed without destroying the overall climate environment in the accommodating chamber 112. When it is necessary to make interface connections or parameter adjustments to the precision electronic components in the accommodating chamber 112, it is only necessary to open the outer door assembly 14, and then extend the hand through the operation window 13 to operate the test chamber 1. The design of the operation window 13 allows the operator to directly extend the hand into the test chamber 1 to operate without opening the inner door assembly 12, effectively preventing the climatic environment conditions in the accommodating chamber 112 from changing dramatically and fluctuating, and preventing external dust from entering the accommodating chamber 112; by setting up a double-door structure of the inner door assembly 12 and the outer door assembly 14, the airtightness of the test chamber 1 is ensured during the test process, ensuring the smooth progress of the test.

[0053] Specifically, Figure 2 , Figure 3 As shown, the test chamber 1 also includes a first locking structure, which includes a locking portion 151 and a locking member 152. The locking portion 151 is disposed in the box body 11, and the locking member 152 sequentially passes through the inner door assembly 12 and the locking portion 151 to fix the two. The first locking structure ensures a stable connection between the inner door assembly 12 and the box body 11, so that the inner door assembly 12 can stably block the opening 111 of the box body 11, thereby improving the sealing performance of the test chamber 1; and when the opening 111 needs to be opened, the inner door assembly 12 can be opened quickly and easily by simply removing the locking member 152.

[0054] In this embodiment, the locking member 152 is a round head lock.

[0055] Specifically, the inner door assembly 12 is hinged to the box body 11, and the inner door assembly 12 can rotate around the Z-axis direction to block or open the opening 111. By hingedly connecting the inner door assembly 12 to the box body 11, the inner door assembly 12 can be easily rotated, thereby conveniently blocking or opening the opening 111 of the box body 11; the hinged connection between the inner door assembly 12 and the box body 11 has high strength and stability and is not easily damaged.

[0056] Specifically, Figure 3 As shown, the inner peripheral wall of the box body 11 is provided with a retaining ring 16, and the inner door assembly 12 abuts against the retaining ring 16 when blocking the opening 111. When the inner door assembly 12 blocks the opening 111, the inner door assembly 12 can abut against the retaining ring 16, which can improve the sealing performance in the test chamber 1 to a certain extent; and the retaining ring 16 can increase the overall structural strength of the box body 11, disperse stress, and reduce the risk of deformation of the box body 11.

[0057] In this embodiment, if Figure 3 As shown, a receiving groove 161 is provided on the side of the retaining ring 16 facing the inner door assembly 12, and a second sealing member is accommodated in the receiving groove 161. The second sealing member can provide an additional sealing effect, further ensuring that there is no leakage between the inner door assembly 12 and the box body 11, and the second sealing member can be compressed and tightly fitted between the retaining ring 16 and the inner door assembly 12, effectively ensuring the airtightness of the receiving chamber 112, thereby reducing the impact of the climatic environment conditions in the receiving chamber 112 when the outer door assembly 14 is opened. The material of the second sealing member can be rubber, silicone or polytetrafluoroethylene, which is not limited in this embodiment. For example, the material of the second sealing member in this embodiment is silicone, which has good high temperature resistance and corrosion resistance and a long service life.

[0058] In this embodiment, if Figure 2 As shown, the inner door assembly 12 includes two inner doors 121 distributed along the X-axis direction, and the two inner doors 121 are hinged to the box body 11 on opposite sides. The two inner doors 121 are hinged to the two sides of the box body 11 respectively, so that the two sides of the box body 11 can be evenly stressed, preventing the box body 11 from being deformed or damaged due to uneven stress.

[0059] Furthermore, if Figure 4 As shown, the inner door assembly 12 further includes a heat-insulating plate 122, which extends along the Z-axis direction and is located at the joint of the two inner doors 121. The heat-insulating plate 122 has a fixing portion 1221 and an abutting portion 1222 distributed along the X-axis direction. The fixing portion 1221 is fixedly connected to one of the two inner doors 121, and a first sealing member 1223 is provided on the side of the abutting portion 1222 facing the other inner door 121, and the other inner door 121 can be tightly abutted against the first sealing member 1223. When closing the inner door assembly 12, first close one of the inner doors 121 connected to the fixing portion 1221, and then close the other inner door 121, so that the other inner door 121 is tightly abutted against the first sealing member 1223, so as to achieve sealing at the door gap of the two inner doors 121.

[0060] In this embodiment, the material of this thermal insulation plate 122 is FR4 epoxy resin, which has high strength, good rigidity and good insulation performance, and is not easy to conduct heat. It is used to isolate the temperature conduction between the inside and outside of the test chamber 1 at the door gap of the two inner doors 121 to ensure the airtightness of the test chamber 1.

[0061] In this embodiment, the first sealing member 1223 is made of silicone sponge, which has good thermal conductivity barrier properties and can better block temperature conduction between the inside and outside of the test chamber 1 at the door gap between the two inner doors 121 .

[0062] It should be noted that the inner door 121 and the fixing portion 1221 may be fixed by gluing or by fasteners such as bolts or screws, which is not limited in this embodiment.

[0063] In the specific implementation process, a groove extending along the Z-axis direction is opened on the heat-breaking plate 122 to form abutment 1222, and the first seal 1223 is fixedly connected to the groove of the heat-breaking plate 122. The two can be fixed by gluing, or by bolts, screws and other connecting parts, which is not limited in this embodiment.

[0064] Specifically, if Figure 2 , Figure 5 As shown, an installation opening is opened on the inner door assembly 12, and the operating window 13 is installed on the installation opening. The operating window 13 includes a first flange 131, a second flange 132, an elastic baffle 133 and a fixing member. The first flange 131 and the second flange 132 are respectively arranged on both sides of the inner door assembly 12 along the Y-axis direction, and the elastic baffle 133 is clamped between the first flange 131 and the inner door assembly 12, or between the second flange 132 and the inner door assembly 12. The elastic baffle 133 can block the installation opening, and a groove 1331 is arranged on the elastic baffle 133; the fixing member is used to fix the first flange 131, the second flange 132 and the elastic baffle 133 to the inner door assembly 12. The first flange 131 and the second flange 132 are respectively arranged on both sides of the inner door assembly 12 along the Y-axis direction, ensuring the stability of the operation window 13 installed on the inner door assembly 12; the elastic baffle 133 is clamped between the first flange 131 / the second flange 132 and the inner door assembly 12, which can block the installation port and ensure the airtightness of the accommodating cavity 112 to a certain extent; by arranging a groove 1331 on the elastic baffle 133, the operator can put his hand into the accommodating cavity 112 through the groove 1331, and the elastic baffle 133 is temporarily deformed at this time. After the operation is completed, the elastic baffle 133 will automatically return to its original state to re-block the installation port; the fixing member can fix the first flange 131, the second flange 132 and the elastic baffle 133 on the inner door assembly 12 to prevent the operation window 13 from loosening and falling during long-term use.

[0065] It should be noted that the number of the operation windows 13 is determined by actual needs and is not limited in this embodiment. In this embodiment, there are two operation windows 13, which are respectively arranged on the two inner doors 121 of the inner door assembly 12, so as to facilitate the operator to operate with both hands.

[0066] Specifically, one of the first flange 131 and the second flange 132 is provided with a blind hole, the other is provided with a first through hole, the elastic blocking piece 133 is provided with a second through hole, the inner door assembly 12 is provided with a third through hole, and the fixing piece is passed through the first through hole, the second through hole, the third through hole and the blind hole to fix the first flange 131, the second flange 132 and the elastic blocking piece 133 to the inner door assembly 12. Through this arrangement, it is possible to ensure that the fixing piece can be passed through the first flange 131, the second flange 132, the elastic blocking piece 133 and the inner door assembly 12 to make them fixedly connected, and the fixing piece located on at least one side of the inner door assembly 12 does not contact the external environment or the accommodating chamber 112, that is, it is ensured that the accommodating chamber 112 and the external environment cannot generate heat conduction through the fixing piece, and the airtightness of the test chamber 1 is further ensured.

[0067] In this embodiment, the number of blind holes, first through holes and second through holes is multiple, and the multiple blind holes and the multiple first through holes are respectively distributed in a circle on the first flange 131 and the second flange 132, the second through holes are distributed in a circle on the elastic baffle 133, and the third through holes are distributed in a circle on the inner door assembly 12. The multiple blind holes, the multiple first through holes, the multiple second through holes and the multiple third through holes are connected one by one, and a fixing member can be passed through the correspondingly connected first through holes, second through holes, third through holes and blind holes.

[0068] In this embodiment, if Figure 5 As shown, the slots 1331 are arranged in a cross shape. The cross-shaped slots 1331 allow the elastic blocking piece 133 to deform more flexibly, so as to facilitate the arm to extend into the test chamber 1, and can ensure timely sealing during and before and after operation, reduce heat exchange between the accommodating chamber 112 and the external environment, and prevent external dust from entering the accommodating chamber 112.

[0069] Specifically, the first flange 131 and the second flange 132 are both made of FR4 epoxy resin, which has high strength, good rigidity and good insulation performance and is not easy to conduct heat. It is used to isolate the temperature conduction at the operating window 13 inside and outside the test chamber 1 to ensure the airtightness of the test chamber 1.

[0070] Specifically, the material of the inner door assembly 12 is transparent glass. The inner door assembly 12 is set to be made of transparent glass material, which can facilitate observation of the situation in the accommodating cavity 112, and can be used to observe and operate the precision electronic components in the accommodating cavity 112 through the inner door assembly 12. Specifically, the inner door assembly 12 in this embodiment is made of tempered glass, which has good light transmittance, good temperature resistance and corrosion resistance, can withstand high and low temperatures and drastic temperature changes in the test chamber 1, and can also withstand corrosive gases released by precision electronic components.

[0071] It should be noted that in order to ensure that the inner door assembly 12 can still ensure the stability of the climate and environmental conditions of the accommodating cavity 112 after the outer door assembly 14 is opened, the inner door assembly 12 is a double-layer hollow structure.

[0072] Specifically, if Figure 1 As shown, the outer door assembly 14 has an observation window 141 , and the material of the observation window 141 is transparent glass. When the climate environment simulation test box is working, the situation in the accommodating cavity 112 can be observed through the observation window 141 .

[0073] Specifically, the outer door assembly 14 is hinged to the box body 11, and the outer door assembly 14 can rotate around the Z-axis direction to seal the inner door assembly 12 and the box body 11. The outer door assembly 14 is hinged to the box body 11 so that the outer door assembly 14 can be easily rotated; the hinged connection between the outer door assembly 14 and the box body 11 has high strength and stability and is not easy to be damaged.

[0074] Specifically, if Figure 1 , Figure 6 As shown, the climate environment simulation test box also includes a second locking structure 17, which includes a clamping portion 171 and a latch 172. The clamping portion 171 is arranged at the top and / or bottom of the box body 11, and the latch 172 is rotatably arranged at the top or bottom of the outer door assembly 14. The latch 172 can be rotated to lock or unlock with the clamping portion 171. The second locking structure 17 is used to ensure a stable connection between the outer door assembly 14 and the box body 11, so that the outer door assembly 14 can be stably sealed and covered on the inner door assembly 12 and the box body 11, thereby improving the sealing performance of the test chamber 1; and when the outer door assembly 14 needs to be opened, the outer door assembly 14 can be opened quickly and easily by simply rotating the latch 172.

[0075] In this embodiment, if Figure 1 As shown, the outer door assembly 14 includes two outer doors 142 distributed along the X-axis direction, and the two outer doors 142 are hinged to the box body 11 on opposite sides. The two outer doors 142 are hinged to the two sides of the box body 11 respectively, so that the two sides of the box body 11 can be evenly stressed, preventing the box body 11 from being deformed or damaged due to uneven stress.

[0076] Specifically, the outer door assembly 14 has a first cavity inside, and the first cavity is filled with a heat-insulating material. The heat-insulating material filled in the first cavity effectively blocks the heat conduction path inside and outside the outer door assembly 14, ensuring that the temperature condition in the test chamber 1 is not affected by the outside world, and ensuring the accuracy and reliability of the test results.

[0077] Specifically, the box 11 has a second cavity inside, and the second cavity is filled with heat-insulating material. The heat-insulating material filled in the second cavity effectively blocks the heat conduction path inside and outside the box 11, ensuring that the temperature condition in the test chamber 1 is not affected by the outside world, and ensuring the accuracy and reliability of the test results.

[0078] In order to ensure that the temperature condition in the test chamber 1 is not easily affected by the outside world, the inner door assembly 12 is usually thicker, resulting in a heavier inner door 121. In order to increase the bearing capacity of the box 11 for the inner door assembly 12, in this embodiment, Figure 7 As shown, a reinforcing ring 113 is provided at the opening 111 of the second cavity inside the box body 11. The cross section of the reinforcing ring 113 is in the shape of an "X" and is fixed to the bottom of the second cavity, thereby enhancing the strength of the opening 111 of the box body 11 and ensuring that the box body 11 can stably carry the inner door assembly 12.

[0079] Furthermore, the reinforcing ring 113 is a hollow structure, thereby reducing the weight of the box body 11, reducing the use of materials, and reducing production costs.

[0080] Specifically, Figure 7 As shown, a partition 114 is provided inside the accommodating chamber 112 of the test chamber 1 to separate the accommodating chamber 112 into a test chamber 1121 and an air conditioning chamber 1122. The precision electronic components are located in the test chamber 1121. The air conditioning chamber 1122 and the test chamber 1121 are connected through an air outlet and an air inlet. An evaporator, a heater, a humidifying tube, a fan, etc. are placed in the air conditioning chamber 1122. The air in the air conditioning chamber 1122 that meets certain temperature and humidity conditions is sent to the test chamber 1121 through the fan, so that the natural environment conditions of temperature and humidity with the required specifications are simulated in the test chamber 1121, and the precision electronic components complete the relevant tests under the test conditions of the simulated environment.

[0081] Specifically, Figure 1 As shown, the climate environment simulation test box also includes a unit room 2, which is used to provide cold energy for the evaporator in the air conditioning cavity 1122. Specifically, the unit room 2 also includes a refrigeration system consisting of a compressor, a condenser, a valve, and a plurality of pipes, which is beneficial to provide cold energy for the evaporator of the air conditioning cavity 1122.

[0082] Furthermore, for some test conditions with certain requirements on humidity, the unit room 2 in this embodiment also includes a humidifying mechanism capable of generating humidity, and moisture is provided to the air-conditioning cavity 1122 through the humidifying mechanism, such as the humidifying mechanism can be a steam humidifier, etc.

[0083] Specifically, Figure 1 As shown, the climate environment simulation test box also includes a control room 3, which can provide strong and weak current control for the climate environment simulation test box, control the power on and off, signal reception, transmission and processing of the climate environment simulation test box, and maintain the normal operation of the climate environment simulation test box.
