In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom" and the like indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In one embodiment, Figure 1-4 As shown, an aging test device for automotive electronic products includes a low-temperature box 1, a high-temperature box 2 is provided on the top of the low-temperature box 1, a connecting box 3 is fixedly connected to the top of the low-temperature box 1 and the bottom of the high-temperature box 2, a first cylinder 4 is fixedly sleeved in the middle of the bottom of the low-temperature box 1, a lower sealing plate 5 is fixedly connected to the output end of the first cylinder 4, and the lower sealing plate 5 is plugged into the bottom of the inner cavity of the connecting box 3, an air conditioner 6 is fixedly connected to the left side of the low-temperature box 1, and the output end of the air conditioner 6 passes through the interior of the low-temperature box 1, a second cylinder 7 is fixedly connected to the middle of the top of the high-temperature box 2, and an upper sealing plate 8 is fixedly connected to the output end of the second cylinder 7, and the upper sealing plate 8 is plugged into the top of the inner cavity of the connecting box 3, a hot air blower 9 is fixedly connected to the left side of the high-temperature box 2, and the output end of the hot air blower 9 passes through the interior of the high-temperature box 2, a placement frame 10 is placed on the top surface of the lower sealing plate 5, and connection blocks 11 are fixedly connected to the left and right sides of the placement frame 10.

[0021] In order to connect the placement frame 10 to the upper sealing plate 8 so that the upper sealing plate 8 can pull the placement frame 10 into the high-temperature box 2, a first slot 12 is opened on the top surface of the two connecting blocks 11, and connecting plates 13 are fixedly connected to the left and right sides of the bottom surface of the upper sealing plate 8. The facing surfaces of the two connecting blocks 11 and near the bottom are fixedly connected with a third cylinder 14, and the output ends of the two third cylinders 14 are fixedly connected with a first plug-in block 15, and the two first plug-in blocks 15 are respectively inserted into adjacent first slots 12.

[0022] In order to prevent the placement frame 10 from moving at will when placed on the lower sealing plate 5, a second slot 16 is opened at the bottom of the two connecting blocks 11, and the left and right sides of the top surface of the lower sealing plate 5 are fixedly connected with second plug-in blocks 17, and the two second plug-in blocks 17 are respectively adapted to the adjacent second slots 16.

[0023] In order to improve the sealing effect when the lower sealing plate 5 and the upper sealing plate 8 are inserted into the connecting box 3, the outer surfaces of the lower sealing plate 5 and the upper sealing plate 8 are fixedly sleeved with sealing strips 18, and the sealing strips 18 are made of EPDM material. EPDM material has good heat resistance and cold resistance, so that the sealing strips 18 will not be easily damaged even if they are in the low temperature box 1 and the high temperature box 2 for a long time.

[0024] In order to facilitate the placement of electronic products into the placement frame 10 , the middle of the front side of the connection box 3 is provided with a take-in and put-out opening, and the middle of the front side of the connection box 3 is hingedly connected with a sealing door 19 .

[0025] In order to support the device, a support leg 20 is fixedly connected to the bottom surface of the low temperature box 1 . There are four support legs 20 , which are respectively arranged at the four corners of the low temperature box 1 .

[0026] Working principle: When the utility model is used, firstly, the cold air machine 6 and the hot air machine 9 are used to inject cold and hot air into the low temperature box 1 and the high temperature box 2 respectively, so as to create a high temperature environment and a low temperature environment, and then the sealing door 19 is opened, and the electronic product is placed in the placement frame 10 through the access opening, and then the sealing door 19 is closed, and then the second cylinder 7 is started, and the second cylinder 7 drives the upper sealing plate 8 to rise. Since the second plug-in block 17 is plugged into the second slot 16, the upper sealing plate 8 will drive the placement frame 10 to rise and enter the high temperature box 2, so that the electronic product is in the high temperature box. 2, when it is necessary to switch to a low temperature environment, the second cylinder 7 pushes the upper sealing plate 8 down, so that the placement frame 10 returns to the connection box 3, and the upper sealing plate 8 is plugged into the top of the inner cavity of the connection box 3, so that the temperature in the high temperature box 2 cannot circulate with the temperature in the connection box 3, and at the same time, the bottom surface of the placement frame 10 is placed on the lower sealing plate 5, and the two first plug-in blocks 15 are also just plugged into the two first slots 12, so that the placement frame 10 is difficult to move on the lower sealing plate 5, and then the third cylinder 14 contracts, driving the second plug-in block 17 to move, so that The second plug block 17 is removed from the second slot 16, so that the connection frame 10 is no longer connected to the upper sealing plate 8. Then the first cylinder 4 drives the lower sealing plate 5 to descend, and the lower sealing plate 5 drives the placement frame 10 to descend, so that the placement frame 10 descends into the low-temperature box 1, so that the electronic product is in the high-temperature environment of the low-temperature box 1. When the electronic product is removed from the low-temperature box 1, the first cylinder 4 pushes the lower sealing plate 5 to rise, and the connection frame 10 is sent back to the connecting box 3. The lower sealing plate 5 is plugged into the bottom of the inner cavity of the connecting box 3, so that the temperature in the low-temperature box 1 cannot be connected to the temperature of the connecting box 3. The temperature circulates in the box 3 in the above manner. When the electronic product is switched between high temperature and low temperature, there is no need to open the device. It is only necessary to return the placement frame 10 to the connecting box 3, and isolate the connecting box 3 from the low temperature box 1 or the high temperature box 2, so that the temperature of the low temperature box 1 and the high temperature box 2 cannot flow, avoiding the fusion of a large amount of low temperature air and high temperature air. Only a small amount of low temperature air and high temperature controlled air will be fused in the connecting box 3, which greatly reduces the loss of high temperature and low temperature, and greatly improves the utilization rate of temperature.

[0027] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
