[0047] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] See also Figure 1-6 The present invention discloses an aging test device 1, which is used to perform an aging test on a product to be tested, wherein the product to be tested includes a charging pile or a component inside the charging pile that needs an aging test. The device includes a box 13, at least two test chambers 11 and a load chamber 12, wherein the test chamber 11 and the load chamber 12 are arranged in the box 13, and the test chamber 11 and the load chamber 12 are respectively arranged in independent spaces of the box 13, and any two test chambers 11 are independently arranged, wherein the test chamber 11 is used to load the product to be tested, and the load chamber 12 is used to place a load 2.

[0049] Specifically, the test chamber 11 and the load chamber 12 are independently arranged, and the space between the test chamber 11 and the load chamber 12 is not interconnected, so that the ambient temperature in the test chamber 11 does not change due to the change of the ambient temperature in the load chamber 12. The load 2 is placed in the load chamber 12, wherein the load 2 is a load 2 power supply, which supplies power to the product to be tested and provides a corresponding test environment, so that the performance test of the product to be tested is performed when the load 2 power supply is connected, and the test results under the load 2 mode are obtained, and the product to be tested in the test chamber 11 is electrically connected to the load 2 in the load chamber 12.

[0050] Furthermore, any two test chambers 11 are independently set up to create different test temperatures in each test chamber 11. Products to be tested with different test requirements can be placed in the aging test equipment 1 for testing. Each product to be tested can be tested under a corresponding test environment, thereby improving the accuracy of the test results. The equipment can realize aging tests on different products to be tested at different temperatures in different chambers, thereby improving the convenience of using the equipment.

[0051] Each wall of the box body 13 is provided with a filling layer, and the filling layer is filled with thermal insulation materials such as rock wool and asbestos. The outer surface of the box wall is made of fiberglass board, which can ensure that the internal heat energy will not be transferred to the outside through the box wall, reduce heat conduction, and prevent people from touching the equipment and getting hot. Further, the box body 13 is provided with a door 137 corresponding to the test bin body 11 and the load bin body 12. By opening the door 137, the product to be tested can be placed in the test bin body 11 and the load 2 can be placed in the load bin body 12. The doors 137 of the test bin body 11 and the load bin body 12 are both thermally insulated.

[0052] The box body 13 includes an air duct portion 131 and a accommodating portion, the air duct portion 131 is connected to the accommodating portion, the air duct and air outlet of the test chamber 11 and the load chamber 12 are arranged in the air duct portion 131, the loaded parts of the test chamber 11 and the load chamber 12 are arranged in the accommodating portion, and the air duct portion 131 is arranged at a height higher than the accommodating portion.

[0053] The test chamber body 11 includes a test intermediate air duct 111, a test air inlet duct 112 and a test air outlet duct 113, wherein the test air inlet duct 112 is connected to the test air outlet duct 113 via the test intermediate air duct 111, wherein the test intermediate air duct 111, the test air inlet duct 112 and the test air outlet duct 113 are arranged on the air duct portion 131 of the box body 13, and the air duct portion 131 is arranged on the top of the box body 13, so that the air outlets of all air ducts can face upward, which is convenient for centralized collection of the exhaust gas of the equipment and subsequent discharge, avoiding the accumulation of a large amount of hot gas.

[0054] The test chamber body 11 is divided into an air inlet 114, a test section 115, and an air outlet 116. The product to be tested is placed in the test section 115. The air inlet 114 and the air outlet 116 are respectively arranged on both sides of the test section 115. The test air inlet duct 112 is connected to the air inlet 114, and the test air outlet duct 113 is connected to the air outlet 116. Specifically, air enters the air inlet 114 from the test air inlet duct 112, passes through the product to be tested on the test section 115, and is then blown out to the test air outlet duct 113 through the air outlet 116.

[0055] Specifically, air enters from the test air inlet duct 112, passes through the air inlet portion 114, the test portion 115, and the air outlet portion 116 in sequence, and then exits from the test air outlet duct 113, thereby connecting the internal environment with the outside, and allowing air circulation to occur inside. Through this air circulation method, the heat energy exchange between the internal environment and the external environment can be accelerated, thereby achieving the purpose of lowering the temperature; by setting up the test intermediate air duct 111, the test air inlet duct 112 and the test air outlet duct 113 can be connected, so that the air output from the test air outlet duct 113 enters the test air inlet duct 112 again, thereby forming an air circulation. This air circulation method can be used when the internal air is heated, which can accelerate the rise in the internal environment temperature. Through the cooperation of the test air inlet duct 112, the test intermediate air duct 111 and the test air outlet duct 113, the purpose of regulating the temperature in the test chamber 11 is achieved.

[0056] The test chamber body 11 includes an intermediate air valve 1111, an air outlet air valve 1131, and an air inlet air valve 1121. The air outlet air valve 1131 is arranged in the test air outlet air duct 113, the intermediate air valve 1111 is arranged in the test intermediate air duct 111, and the air inlet air valve 1121 is arranged in the test air inlet air duct 112.

[0057] Specifically, the air outlet valve 1131 is set at the air inlet of the test air outlet duct 113, and the air inlet valve 1121 is set at the air inlet of the test air inlet duct 112. The air inlet valve 1121 can close or open the test air inlet duct 112 to control the air entering from the test air inlet duct 112, and the air outlet valve 1131 can close or open the test air outlet duct 113 to control the internal air to flow from the test air outlet duct 113 to the outside.

[0058] The box body 13 includes a load circulation fan 132 and a test circulation fan 133. The load circulation fan 132 is arranged in the load ventilation duct 123, and the test circulation fan 133 is arranged in the test air outlet duct 113. The air outlet direction of the load circulation fan 132 is toward the air outlet of the load ventilation duct 123, and the air outlet direction of the test circulation fan 133 is toward the air outlet valve 1131.

[0059] Close the air outlet valve 1131 and the air inlet valve 1121, open the intermediate air valve 1111, and start the test circulation fan 133, so that the air can pass through the air inlet portion 114, the test portion 115, the air outlet portion 116, the test air outlet duct 113, the test intermediate duct 111, and the test air inlet duct 112 in sequence, so that air circulates inside the test chamber 11. Since the product to be tested will generate heat energy during the aging test, the temperature of the test chamber 11 will continue to rise during the internal circulation.

[0060] Open the air outlet valve 1131 and the air inlet valve 1121, close the intermediate air valve 1111, and start the test circulation fan 133, so that air can enter the air inlet portion 114 from the air inlet of the test air inlet duct 112, pass through the product of the test portion 115 and the air outlet portion 116, and then flow to the external environment through the air outlet of the test air outlet duct 113. At this time, the internal air can be exchanged with the external air, and heat conduction can be achieved through the external circulation of the air in the test chamber body 11, thereby accelerating the reduction of the internal temperature.

[0061] It can be understood that through the cooperation of the air outlet valve 1131, the air inlet valve 1121, and the intermediate air valve 1111, the gas environment of the test chamber 11 can achieve internal circulation or external circulation, thereby achieving the purpose of raising or lowering the temperature and realizing the purpose of automatic control of the temperature of the test chamber 11.

[0062] The test chamber 11 is provided with a heating element 1122, which is installed in the test air inlet duct 112. Specifically, in the internal circulation mode, the heating element 1122 can generate heat, thereby accelerating the temperature increase in the test chamber 11, accelerating the formation of the test environment, and making the test process faster.

[0063] Optionally, a pulling member 1123 is provided on the air outlet valve 1131 and the air inlet valve 1121, and the air outlet valve 1131 and the air inlet valve 1121 can be manually opened by pulling the pulling member 1123. It can be understood that the air outlet valve 1131 and the air inlet valve 1121 can be manually operated, and the air circulation mode inside the test chamber 11 can be manually changed. After the electrical control mode fails, manual processing can be performed to avoid excessive internal temperature that cannot conduct heat to the outside, thereby improving the safety of the equipment.

[0064] The testing section 115 is provided with a testing frame 1152, and the testing frame 1152 can be used to place the product to be tested. The testing frame 1152 is provided with multiple testing stations. After the product to be tested is loaded with a fixture, it can be placed in the testing station for aging test. Any test station is provided with a guide rail 1153, and the guide rail 1153 is provided with multiple rolling bars 1154. The rolling bars 1154 can allow the fixture loaded with the product to be tested to better enter the testing station.

[0065] The guide rail 1153 is provided with a guide piece, so that the jig can move along the direction of the guide rail 1153 to prevent the jig from exceeding the position defined by the guide rail 1153 .

[0066] The test frame 1152 is provided with a back plate adjustment member 1156 and a supporting block 1155. The back plate adjustment member 1156 and the supporting block 1155 are arranged at a position of the test frame 1152 close to the air outlet portion 116. When the fixture completely enters the test station, the supporting block 1155 can support the fixture to prevent it from moving too far and prevent it from being pushed into the air outlet portion 116.

[0067] Specifically, when the product to be tested is placed on the test rack 1152, a matching fixture needs to be loaded. The fixture is provided with a plug with a uniform model. The plug on the corresponding fixture on the test rack 1152 is provided with a corresponding test interface. When the fixture is loaded with the product to be tested and pushed into the test station of the tester, the plug is connected to the test interface. The test interface is set on the test backplane. Since the sizes of each product to be tested are different, the specific position of the backplane adjustment part 1156 can be adjusted to adapt to the size of each product to be tested, so that the interface position of the test backplane corresponds to that of the product to be tested.

[0068] The test chamber body 11 is provided with a baffle 117 and an air regulating plate 118, the baffle 117 is provided between the air inlet portion 114 and the test portion 115, the air regulating plate 118 is connected to the baffle 117, and the air regulating plate 118 is provided in the air inlet portion 114. Specifically, the baffle 117 is provided with a ventilation hole 134, and the air inlet portion 114 allows the air in the air inlet portion 114 to flow to the test portion 115. At the same time, the baffle 117 is provided between the air inlet portion 114 and the test portion 115, so as to prevent the air in the test air inlet duct 112 from directly entering the test portion 115, and the air must pass through the air inlet portion 114 and the baffle 117 to enter the test portion 115.

[0069] The air regulating plate 118 is arranged at an angle to the baffle 117, with one end of the air regulating plate 118 fixed on the baffle 117 and the other end facing the test air inlet duct 112, so that the regulating plate can divert the internal air at the air inlet portion 114. An air regulating plate 118 is provided corresponding to each test station. By setting the air regulating plate 118, part of the hot air can be blown to the bottom and part can flow to the test portion 115, so that the wind can flow to the lowest layer, so that the air in the air inlet portion 114 can flow from top to bottom, thereby avoiding the hot air from gathering at the top and making the temperature in the air inlet portion 114 more uniform.

[0070] The air regulating plates 118 are fixed to the baffle 117 by fasteners, and the distance between adjacent air regulating plates 118 is adjustable. By adjusting the spacing between the air regulating plates 118, the height of the test station can be adjusted, so that the air inlet area of ​​the air inlet of the test station can be enlarged or reduced, thereby adjusting the air intake volume and making the temperature adjustment speed faster.

[0071] As an embodiment, the baffle 117 and the air regulating plate 118 are arranged on the warehouse door 137. It can be understood that the air inlet part 114 is arranged on the warehouse door 137, and the air outlet of the test air inlet duct 112 faces the warehouse door 137. After being diverted by the air regulating plate 118 and passing through the baffle 117, the wind enters the test part 115. By setting it on the warehouse door 137, different adjustment plate setting positions can be set corresponding to different products to be tested. When conducting tests, more corresponding warehouse doors 137 can be directly used, and aging tests can be conducted faster.

[0072] The test chamber 11 is provided with a first temperature detection component 1151 and a first smoke sensor 1161. A first temperature detection component 1151 is provided at any test station, and the first smoke sensor 1161 is provided at the air outlet 116. Specifically, the first temperature detection component 1151 is used to detect the temperature value in the test chamber 11. Each test station is provided with a first temperature detection component 1151, and the temperature value can be tested at each test station, and the temperature value at the current test station can be obtained in real time. The first smoke sensor 1161 is arranged close to the air inlet of the test air outlet duct 113, and can sense whether smoke appears inside. When smoke appears, an alarm can be issued, and the operation of the aging test equipment 1 can be stopped in time. When safety problems occur, the user can be reminded in time, thereby improving the safety of the equipment.

[0073] Optionally, the test chamber 11 is provided with a temperature control indicator light, which can display the current temperature condition in the test chamber 11. When it is displayed in red, the temperature in the test chamber 11 is overtemperature; when it is displayed in yellow, it is low temperature; when it is displayed in green, it is normal temperature.

[0074] The load storage body 12 includes a ventilation portion 121, a load mounting portion 122, and a load ventilation duct 123. The load mounting portion 122 is connected to the ventilation portion 121, and the ventilation portion 121 is connected to the load ventilation duct 123. The box body 13 is provided with ventilation holes 134 at positions corresponding to the load storage body 12.

[0075] Specifically, the load ventilation duct 123 is arranged in the duct part 131 of the box body 13, so that the gas in the load ventilation duct 123 can be discharged in one direction. The load 2 is installed in the load installation part 122. The ventilation hole 134 allows the load installation part 122 and the ventilation part 121 to be connected to the outside. The ventilation part 121 is connected to the load ventilation duct 123. The load circulation fan 132 is turned on to allow air to enter from the ventilation hole 134 and be output through the load ventilation duct 123, so that the load 2 is at a stable temperature and the temperature in the load installation part 122 is prevented from continuing to rise.

[0076] The load bin 12 is provided with a second temperature detection member 135 and a second smoke sensor 136, and the second temperature detection member 135 and the second smoke sensor 136 are provided in the ventilation portion 121.
