[0002] Nowadays, portable electronic devices (such as mobile phones, tablets, etc.) are usually tested in test cabinets for functional and stability testing before they are launched. This is to ensure that the portable electronic devices can operate their intended functions normally and remain stable and reliable after long-term use.

[0003] The test cabinet includes a frame, a test assembly and a cabinet. The frame and the test assembly are both arranged in the cabinet. The frame is used to fix the electronic equipment to be tested, and the test assembly is used to electrically connect to the electronic equipment to be tested for testing. A number of through holes are provided on the wall of the cabinet to provide heat exchange channels between the inside and outside of the cabinet.

[0004] However, to improve test efficiency, dozens or even hundreds of portable electronic devices are usually placed in a test cabinet for simultaneous testing, which results in a huge amount of heat generated in the test cabinet. The above-mentioned test cabinet cannot meet the heat dissipation requirements, resulting in excessively high temperatures inside the test cabinet, posing a safety hazard. Utility Model Content

[0050] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0051] The present disclosure provides a test cabinet, such as Figure 1 As shown, the test cabinet includes a cabinet body 1, a frame body 2, a test component 3 and a flow guide component 4.

[0052] Among them, the cabinet 1 has a accommodating cavity 11, an air inlet 12 and an air outlet 13, the air inlet 12 and the air outlet 13 are respectively connected to the accommodating cavity 11, the frame 2, the test component 3 and the guide component 4 are respectively fixed in the accommodating cavity 11, the air inlet 12 is used to be connected to the air outlet of the refrigeration equipment, the frame 2 is used to fix the electronic device 01 to be tested, the test component 3 is used to be electrically connected to the electronic device 01 to be tested, and the air flow path between the air inlet 12, the guide component 4 and the air outlet 13 passes through the frame 2.

[0053] The test assembly 3 includes multiple test units, each of which is electrically connected to at least one electronic device 01 to be tested and to an external control device, which can be a computer. In practice, a tester sends a test command to the test unit through the external control device, such as a camera opening command, a power-on command, a stability test command (sending a certain command continuously a preset number of times), etc. The test unit is used to perform a corresponding test on the electronic device 01 to be tested based on the test command.

[0054] In this way, by setting up a guide component 4 in the test cabinet, since the air flow path between the air inlet 12, the guide component 4 and the air outlet 13 passes through the frame 2, the guide component 4 can guide the cold air flowing into the accommodating cavity 11 from the air inlet 12, so that the cold air passes through the frame 2, and after sufficient heat exchange with the electronic device 01 to be tested fixed on the frame 2, it flows out of the cabinet 1 through the air outlet 13, thereby avoiding heat squeezing inside the cabinet 1 during testing and improving the safety of the test.

[0055] like Figure 1 As shown, the cabinet 1 is a cubic structure, and has a cubic accommodating cavity 11 inside the cabinet 1. The cabinet 1 is usually made of metal material to ensure that the test cabinet has sufficient mechanical strength.

[0056] In some examples, such as Figure 1 As shown, the test cabinet further includes a wheel body 5 .

[0057] Specifically, see Figure 1 The test cabinet may include four wheel bodies 5, which are connected to the bottom surface of the cabinet 1. The four wheel bodies 5 can be rotatably connected to the bottom surface of the test cabinet respectively.

[0058] Optionally, the four wheels 5 may be distributed in a 2×2 matrix, and the geometric centers of the four wheels 5 may be located on the same vertical line as the center of mass of the test cabinet, thereby improving the stability of the test cabinet.

[0059] Optionally, the test cabinet can be integrated with a refrigeration device, which can be an air conditioner. In some examples, the cabinet 1 can have two accommodating chambers 11, which are respectively connected through an air inlet 12 and an air outlet 13. One of the accommodating chambers 11 is used to fix the refrigeration device, and the other accommodating chamber 11 is used to fix the above-mentioned frame 2, test component 3, guide component 4 and the electronic device 01 to be tested. In implementation, the air outlet of the refrigeration device is directly connected to the above-mentioned air inlet 12, and the exhaust direction of the external unit of the refrigeration device points in the direction away from the other accommodating chamber 11. When the external unit exhausts air, the air pressure in the accommodating chamber 11 for installing the refrigeration device is reduced, and the gas in the other accommodating chamber 11 is extracted through the air outlet 13. In some examples, the refrigeration device can also be fixed on the outer wall of the cabinet 1.

[0060] In some examples, the cabinet 1 has a first wall 1 a and a second wall 1 b that are oppositely arranged.

[0061] See also Figure 1 and Figure 2 The first wall 1a and the second wall 1b are two opposite walls of the cabinet 1 in the length direction. The first wall 1a and the second wall 1b are arranged opposite and parallel to each other. A receiving cavity 11 is formed between the first wall 1a, the second wall 1b, the top wall of the cabinet 1, and the bottom wall of the cabinet 1. The frame 2 has a plate-like structure. The frame 2 is located in the receiving cavity 11, and the two ends of the frame 2 are respectively connected to the first wall 1a and the second wall 1b. The frame 2 is arranged parallel to the top wall of the cabinet 1. The frame 2 has a plurality of fixing seats 21, each of which is used to fix an electronic device 01 to be tested.

[0062] The plurality of fixing seats 21 are distributed at intervals along a first direction, where the first direction is a direction from the first wall 1 a to the second wall 1 b .

[0063] Specifically, the opening of the fixing seat 21 may be directed at an angle to the vertical direction. In this way, after the electronic device 01 to be tested is assembled on the frame 2, the contact area between the electronic device 01 to be tested and the air flow can be increased, thereby improving heat dissipation efficiency.

[0064] For example, the angle between the opening of the fixing seat 21 and the vertical direction may be 60°.

[0065] Exemplarily, each frame 2 may have 20 fixing seats 21 .

[0066] In some examples, the air guide assembly 4 includes a first fan 41 and a second fan 42 .

[0067] like Figure 1 and Figure 2As shown, the air guide assembly 4 includes a first fan 41 and a second fan 42. The first fan 41 is used to supply air in the length direction of the cabinet 1, and the second fan 42 is used to supply air in the width direction or height direction of the cabinet 1.

[0068] Specifically, see Figure 1 and Figure 2 The air inlet 12 and the air outlet 13 are both arranged on the first wall 1a of the cabinet 1, and the distance from the air inlet 12 to the top wall of the cabinet 1 is smaller than the distance from the air outlet 13 to the top wall of the cabinet 1, that is, the air inlet 12 is higher than the air outlet 13. The first fan 41 is fixed on the first wall 1a and is connected to the air inlet 12. The first fan 41 is used to supply air along the first direction. The second fan 42 is fixed on the third direction of the frame 2, and the second fan 42 is used to supply air along the fourth direction.

[0069] The third direction is perpendicular to the first direction, and the fourth direction is opposite to the third direction.

[0070] In practice, since the air flowing into the accommodating cavity 11 through the air inlet 12 is cold air and the density of the cold air is relatively large, setting the air inlet 12 above the air outlet 13 can allow the cold air to flow into the accommodating cavity 11 and then move downward spontaneously, thereby contacting more electronic devices 01 to be tested, thereby improving the heat dissipation efficiency.

[0071] Furthermore, the plane defined by the first direction and the third direction may be a horizontal plane, so that the second fan 42 can be used to supply air in the width direction of the cabinet 1 .

[0072] During implementation, cold air flows from the first wall 1a into the accommodating cavity 11 through the air inlet 12, and the first fan 41 is used to push the cold air to move in the first direction, thereby preventing the cold air from exchanging heat only with some electronic devices 01 to be tested close to the air inlet 12, and being unable to exchange heat with some electronic devices 01 to be tested far away from the air inlet 12.

[0073] like Figure 1 As shown, the diversion assembly 4 includes a diversion interface pipe, and the outlet end of the diversion interface pipe and the air outlet 13 are distributed on both sides of the frame 2.

[0074] Optionally, one end of the guide interface duct is connected to the air inlet 12, and the other end is connected to the air inlet port of the first fan 41. This prevents the cold air from entering the accommodating chamber 11 from the air inlet 12 in a diffused manner. Instead, the cold air is ensured to enter the first fan 41 directly. Under the air supply of the first fan 41, the cold air is moved in the first direction as much as possible, thereby promoting heat exchange between the cold air and some electronic equipment 01 to be tested near the second wall 1b, thereby preventing heat accumulation in this area.

[0075] Furthermore, the first fan 41 can be installed in the third direction of the frame 2, and the first fan 41 can be arranged opposite the second fan 42. In this way, the cold air can be moved in the fourth direction under the action of the second fan 42, thereby improving the heat exchange between the cold air and some electronic devices 01 to be tested that are far away from the second fan 42, thereby avoiding heat accumulation in this area.

[0076] In some possible embodiments, the air guide assembly 4 further includes a third fan 43 , which is installed on the second wall surface 1 b and is used to supply cold air in the second direction.

[0077] The second direction is opposite to the first direction.

[0078] like Figure 4 As shown, the air guide assembly 4 further includes a third fan 43 .

[0079] In some examples, the test cabinet may be equipped with two cooling devices. Accordingly, cabinet body 1 is provided with two air inlets: a first air inlet and a second air inlet. The first air inlet is located on first wall 1a, and the second air inlet is located on second wall 1b. The first air inlet and the second air inlet are respectively connected to the air inlets of the two cooling devices. A third fan 43 is mounted on second wall 1b.

[0080] In some examples, the flow guide assembly 4 further includes a flow guide tube 44 .

[0081] like Figure 3 and Figure 4 As shown, the guide pipe 44 is located in the accommodating cavity 11 and is connected to the cabinet 1. One end of the guide pipe 44 is connected to the air inlet 12, and the other end is fixed on the second wall 1b. The third fan 43 is fixed on the second wall 1b and is connected to the other end of the guide pipe 44.

[0082] Specifically, the flow guide pipe 44 can be fixedly connected to the top wall of the cabinet 1, and one end of the flow guide pipe 44 can be connected to the other end of the above-mentioned flow guide interface pipe.

[0083] By adopting the technical solution provided in the embodiment of the present disclosure, by setting a guide pipe 44 or setting two refrigeration devices, cold air can enter the interior of the accommodating cavity 11 from the second wall 1b, so that heat can be exchanged for some electronic equipment 01 to be tested in the area away from the first wall 1a, avoiding heat accumulation in the area, and improving the safety of the test cabinet.

[0084] Further, see Figure 4The above-mentioned flow guide tube 44 can be connected to the top wall of the cabinet 1 through a fixing member. The fixing member has a semi-annular structure and is adapted to the outer diameter of the flow guide tube 44. The two ends of the fixing member can be connected to the top wall of the cabinet 1 through bolts. Of course, the flow guide tube 44 can also be connected to the top wall of the cabinet 1 using other connection methods, such as bonding and welding, which are not limited in the present embodiment.

[0085] In some possible embodiments, the cabinet 1 includes a body 101 and a cover 102 .

[0086] like Figure 5 As shown, the body 101 has a cylindrical structure and is open at least at one end. The cover 102 covers the opening and is rotatably connected to the body 101 .

[0087] Furthermore, the cover 102 may include a connecting portion and a blocking portion, wherein the connecting portion is rotatably connected to the body 101 , and the blocking portion is arranged on a side of the connecting portion close to the accommodating cavity 11 to block electromagnetic radiation inside the cabinet 1 from overflowing the accommodating cavity 11 .

[0088] In some possible embodiments, such as Figure 1 As shown, the test cabinet includes a plurality of racks 2 , which are arranged at intervals in the vertical direction, wherein the air flow path between the air inlet 12 , the air guide assembly 4 and the air outlet 13 passes through the plurality of racks 2 .

[0089] Specifically, the air outlets of the first fan 41 and the third fan 43 correspond to the multiple frames 2 respectively, and the air guide assembly 4 includes multiple second fans 42 , each of which is located in the third direction of one frame 2 .

[0090] In this way, by setting up the first fan 41 and the third fan 43, the cold air generated by the refrigeration equipment can be delivered layer by layer from top to bottom to the area where each layer of the frame 2 is located, and through the air supply action of the second fan 42 along the fourth direction, the cold air passes through the electronic equipment 01 to be tested one by one along the fourth direction, completing the heat dissipation and avoiding heat accumulation in certain areas of the test cabinet, thereby improving the safety of the test cabinet.

[0091] Figure 6 This is a schematic diagram of the temperature distribution of the test cabinet at a certain moment during the 24-hour use of the test cabinet when the guide component 4 is not set. Figure 6As shown, there is significant heat accumulation in the central area of ​​the test cabinet, with temperatures ranging from 48-55°C. The test cabinet is divided into four areas: upper left, upper right, lower right, and lower right. Considering the air inlet is located above the first wall 1a, it is easy to understand that the average temperature in the lower right area at this moment is the highest, and the average temperature in the upper left area is the lowest. Experimental data shows that the average temperatures in the upper left area at this moment are 43.83°C, the upper right area at 44.07°C, the lower left area at 45.85°C, and the lower right area at 46.78°C. The experimental data is consistent with the above speculation. The local minimum temperature is 23.34°C, occurring in the upper left area, and the local maximum temperature is 49.65°C, occurring in the lower right area.

[0092] Figure 7 This is a schematic diagram of the average temperature of each area in the test cabinet after 24 hours of use, when the guide component 4 is not installed. Figure 7 As shown, the closer to the lower right area, the higher the average temperature, and the average temperature in the lower right area exceeds 45°C.

[0093] Figure 8 This is a schematic diagram of the temperature distribution corresponding to the working condition of the guide component 4, a certain moment in the 24-hour use of the test cabinet, and the angle of the test cabinet. Figure 8 As shown, the temperature of each area within the test cabinet is within the range of 15-40°C. There is no area of ​​significant heat accumulation in the test cabinet. The test cabinet is divided into four areas: upper left, upper right, lower, and lower right. Considering that the air inlet is located above the first wall 1a, it is easy to understand that the average temperature in the lower right area at this moment is the highest, and the average temperature in the upper left area is the lowest. Experimental data shows that the average temperature of the upper left area at this moment is 26.40°C, the average temperature of the upper right area at this moment is 28.81°C, the average temperature of the lower left area at this moment is 31.90°C, and the average temperature of the lower right area at this moment is 31.69°C. The experimental data is consistent with the above speculation. The local minimum temperature is 15.52°C, which occurs in the upper left area, and the local maximum temperature is 40.33°C, which occurs in the lower right area.

[0094] Figure 9 This is a schematic diagram of the average temperature of each area in the test cabinet after 24 hours of use, when the guide component 4 corresponds to the working condition. Figure 9 As shown, by providing the guide component 4, after 24 hours of use, the average temperature of each area of ​​the test cabinet is below 43°C, and the heat dissipation performance of the test cabinet is significantly improved.

[0095] The technical solutions provided by the embodiments of the present disclosure include at least the following beneficial effects:

[0096] The disclosed embodiment provides a test cabinet, in which the air guide component 4 can provide a guiding effect on the airflow in the accommodating cavity 11, so that the airflow path between the air inlet 12 and the air outlet 13 passes through the frame 2. In this way, by arranging the air guide component 4 in the test cabinet, since the airflow path between the air inlet 12, the air guide component 4 and the air outlet 13 passes through the frame 2, the air guide component 4 can guide the cold air flowing into the accommodating cavity 11 from the air inlet 12, so that the cold air passes through the frame 2, fully exchanges heat with the electronic device 01 to be tested fixed on the frame 2, and then flows out of the cabinet 1 through the air outlet 13, thereby avoiding heat compression inside the cabinet 1 during testing and improving the safety of the test.
