In order to ensure the reliability and performance of the switching power supply, strict aging tests must be carried out before the product leaves the factory.

[0003] Traditional aging tests on switching power supplies are usually performed by aging a single or a small number of switching power supplies at the same time. This method is not only time-consuming but also inefficient and cannot meet the needs of large-scale production.

[0004] Nowadays, with the rapid development of the electronics manufacturing industry, higher requirements are placed on the aging test of switching power supplies, that is, how to improve the test efficiency while ensuring the test quality. Summary of the invention

In this embodiment, since the control module 2, the power module 3, the load module 4, the detection module 5, the wireless communication module 6 and the visual monitoring system with the above functions are all prior arts in the art, the above modules are not described in detail here, and the above modules are only briefly indicated in the drawings.

[0061] The control module 2 and the power module 3 are both fixedly installed on the same side of the cabinet 11 in the length direction, and are both located at the bottom of the cabinet 11 .

[0062] There are multiple load modules 4 and detection modules 5, and the multiple load modules 4 and the multiple detection modules 5 correspond one-to-one to the multiple installation spaces 112; the load modules 4 and the detection modules 5 are fixedly installed on one side of the length direction of the cabinet 11, and are aligned with their corresponding installation spaces 112 along the length direction of the cabinet 11, and are located on the same side of the cabinet 11 as the control module 2.

[0063] The wireless communication module 6 is fixedly installed on one side of the cabinet 11 in the length direction, located at the bottom of the cabinet 11, and is located on both sides of the cabinet 11 with the control module 2. In this embodiment, the wireless communication module 6 is preferably WiFi or Bluetooth, which is convenient for remote control by the staff.

[0064] The visual monitoring system is fixedly installed on one side of the cabinet 11 and close to the control module 2, and its visual monitoring range can simultaneously cover the positions of the control module 2, the power module 3, the load module 4 and the detection module 5.

[0068] In this embodiment, since the above-mentioned electrical connection line arrangements are all existing technologies in the field, for the convenience of illustration, the above-mentioned electrical connection lines are omitted.

[0069] The implementation principle of a batch aging device for switching power supplies in the embodiment of the present application is as follows:

[0073] Embodiment 2:

[0074] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the test cabinet 1 also includes multiple temperature control modules 8 and multiple humidity control modules 9.

[0075] The test cabinet 1 further includes a plurality of cover plates 13 and a plurality of locking members 14. The cover plates 13 are used to cover the opening of the installation space 112 to form a certain degree of sealing; the locking members 14 are used to keep the cover plates 13 fixed relative to the cabinet body 11.

[0076] Reference Figure 3 and Figure 4 The cover plate 13 is a rectangular plate-shaped structure as a whole. The cover plate 13 is installed based on the mounting plate 12, and two cover plates 13 are installed on each mounting plate 12; one length side of the cover plate 13 is rotatably connected to one length side of the mounting plate 12, and the rotation axis of the cover plate 13 is parallel to the length direction of the cover plate 13. In this embodiment, the length dimension of the cover plate 13 is preferably matched with the length dimension of the cabinet 11, and the width dimension of the cover plate 13 is preferably matched with the height dimension of the mounting space 112.

[0077] Reference Figure 4 and Figure 5, the cover plate 13 is limited in its rotation relative to the mounting plate 12. When the cover plate 13 is rotated to the limit position in the direction close to the corresponding mounting space 112, the width direction of the cover plate 13 is vertical, and the cover plate 13 can cover the opening on one side of the corresponding mounting space 112 to form a certain degree of sealing; when the cover plate 13 is rotated to the limit position in the direction away from the corresponding mounting space 112, the width direction of the cover plate 13 is horizontal, and the opening on one side of the corresponding mounting space 112 is open.

[0078] Reference Figure 2 and Figure 4 , multiple protrusions 113 are distributed on both sides of the cabinet 11 in the width direction near the two ends of its length direction. When the cover plate 13 is rotated to the extreme position in the direction close to the corresponding installation space 112, there is at least one protrusion 113 corresponding to the cover plate 13. In this embodiment, it is preferred that the cabinet 11 has two protrusions 113 corresponding to each cover plate 13.

[0079] Multiple locking members 14 correspond to multiple cover plates 13 one by one, and the locking members 14 are installed at one end of the corresponding cover plate 13 away from its own rotation axis; the locking members 14 are generally rectangular sheet-like structures. After the locking members 14 are installed on the corresponding cover plate 13, the length direction and width direction of the locking members 14 are respectively parallel to the length direction and width direction of the corresponding cover plate 13; the locking members 14 are slidably connected to the corresponding cover plate 13, and the sliding direction of the locking members 14 is parallel to its own width direction; during the sliding process of the locking members 14 relative to the corresponding cover plate 13, the end of the locking members 14 in the width direction away from the rotation axis of the corresponding cover plate 13 can enter and exit the side of the corresponding cover plate 13 away from its own rotation axis. In this embodiment, it is preferred that one side of the locking member 14 in the thickness direction has a handle 141 for the staff to control its movement, and a corresponding clearance groove 131 is opened on the cover plate 13 for the handle 141 to move with the movement of the locking member 14, and the handle 141 will partially pass through the clearance groove 131 and be located on the outside of the cover plate 13; when the cover plate 13 is in a state of covering the opening of the installation space 112, the handle 141 of the locking member 14 will be located on the side of the cover plate 13 away from the corresponding installation space 112.

[0080] Reference Figure 4 and Figure 5 The locking member 14 is limited in position by the position between its handle 141 and the clearance groove 131 on the cover plate 13, so that its movement relative to the cover plate 13 is limited. When the locking member 14 moves to the limit position in the direction close to the rotation axis of the corresponding cover plate 13, the end of the locking member 14 away from the rotation axis of the corresponding cover plate 13 is just located inside the cover plate 13.

[0081] A locking groove 1131 is provided on the protrusion 113, which is adapted to one end of the locking piece 14 in the width direction. When the corresponding cover plate 13 is in a state of covering the opening of the installation space 112, the corresponding locking piece 14 will be aligned with the corresponding locking groove 1131 along its own movement direction; the cover plate 13 can only be rotated to a state of covering the opening of the corresponding installation space 112 when the locking piece 14 moves to the extreme position in the direction close to its own rotation axis. At this time, the locking piece 14 is controlled to move to the extreme position in the direction away from the rotation axis of the corresponding cover plate 13, and the end of the locking piece 14 away from the rotation axis of the corresponding cover plate 13 will be fully plugged into and matched with the corresponding locking groove 1131. After the plug-in matching, the locking piece 14 and the locking groove 1131 can both limit the corresponding cover plate 13 from rotating relative to the corresponding mounting plate 12.

[0082] Furthermore, in order to improve the position stability of the locking member 14 after being plugged into the locking groove 1131, it is preferred that both the locking member 14 and the cover plate 13 are magnetic and the two are magnetically attracted to each other. At this time, after the locking member 14 is controlled to move relative to the corresponding cover plate 13, the locking member 14 can maintain a fixed relative position with the corresponding cover plate 13 under the force of the magnetic attraction between the two.

[0083] A plurality of first air holes 132 are formed on the cover plate 13 along its thickness direction, and the plurality of first air holes 132 are evenly distributed on the cover plate 13; when the cover plate 13 is rotated to cover the opening of the corresponding installation space 112 and form a certain degree of sealing, the corresponding installation space 112 can communicate with the outside through the plurality of first air holes 132, so as to facilitate heat dissipation and ventilation of the plurality of switching power supplies 10 located in the corresponding installation space 112 during the aging test.

[0084] The test cabinet 1 also includes multiple air permeable parts 15, and the multiple air permeable parts 15 correspond one by one to the multiple cover plates 13; the air permeable parts 15 are generally rectangular sheet structures, and the air permeable parts 15 are installed inside the corresponding cover plates 13, and their length direction and width direction are respectively parallel to the length direction and width direction of the corresponding cover plates 13; the air permeable parts 15 are located on the side of the corresponding locking part 14 close to the corresponding cover plate 13 The axis of rotation, and one side of the air permeable part 15 in the width direction is fixedly connected to one end of the corresponding locking part 14 close to the corresponding cover plate 13. During the movement of the locking part 14 relative to the corresponding cover plate 13, the corresponding air permeable part 15 can move accordingly inside the corresponding cover plate 13.

[0085] A plurality of second air holes 151 are formed on the air permeable member 15 along its thickness direction, and the plurality of second air holes 151 are evenly distributed on the air permeable member 15. The plurality of second air holes 151 correspond one-to-one to the plurality of first air holes 132 and have the same size, and the size of the first air holes 132 and the second air holes 151 along the width direction of the cover plate 13 is equal to the size of the movable range of the locking member 14 relative to the cover plate 13.

[0086] When the locking member 14 moves to the extreme position in the direction close to the rotation axis of the corresponding cover plate 13, the plurality of second air holes 151 on the corresponding air permeable member 15 are completely disconnected from the plurality of first air holes 132 on the corresponding cover plate 13, and both ends of the plurality of second air holes 151 on the corresponding air permeable member 15 are blocked by the inner wall of the corresponding cover plate 13, and the middle position of the plurality of first air holes 132 on the corresponding cover plate 13 is blocked by the corresponding air permeable member 15;

[0087] When the locking member 14 moves to the extreme position in the direction away from the rotation axis of the corresponding cover plate 13, the multiple second air holes 151 on the corresponding air permeable member 15 are completely connected with the multiple first air holes 132 on the corresponding cover plate 13. If the cover plate 13 is in a position to cover the opening of the corresponding installation space 112, the corresponding installation space 112 can communicate with the outside through the multiple first air holes 132 and the multiple second air holes 151.

[0088] When the cover plate 13 is in a position covering the opening of the corresponding installation space 112 and the locking piece 14 is plugged into the locking groove 1131, the air permeability of the corresponding installation space 112 and the outside world can be controlled by controlling the activity of the locking piece 14 to adjust the degree of plugging and fitting between the locking piece 14 and the locking groove 1131, so that the aging test can be carried out under different air permeability conditions according to the use requirements of the switching power supply 10.

[0089] Reference Figure 2 and Figure 3 , multiple temperature control modules 8 and multiple humidity control modules 9 correspond one-to-one to multiple installation spaces 112, are fixedly installed on one side of the length direction of the cabinet 11, are located on the same side of the cabinet 11 as the wireless communication module 6, and are aligned with the corresponding installation spaces 112 along the length direction of the cabinet 11.

[0090] Multiple temperature control modules 8 and multiple humidity control modules 9 are all electrically connected to the power module 3 and are all signal-connected to the control module 2. The power module 3 supplies power to the multiple temperature control modules 8 and the multiple humidity control modules 9, and the control module 2 facilitates the staff to control the multiple temperature control modules 8 and the multiple humidity control modules 9.

[0091] When both side openings of the installation space 112 are covered by the corresponding cover plates 13 and form a certain degree of sealing, the temperature control module 8 can adjust the temperature in the corresponding installation space 112, and the humidity control module 9 can adjust the humidity in the corresponding installation space 112, so that the switching power supply 10 can be subjected to aging tests under different temperature and humidity conditions according to the use requirements. In this embodiment, since the multiple temperature control modules 8 and the multiple humidity control modules 9 with the above functions are common prior arts, they are not described here in detail, and are only briefly shown in the drawings.

[0092] Reference Figure 3 and Figure 6 Furthermore, in order to reduce the probability that different temperature and humidity conditions in different installation spaces 112 affect each other through the installation plate 12 therebetween, it is preferred that a plurality of partitions 16 are also installed on the cabinet 11 .

[0093] The plurality of partitions 16 correspond to the plurality of installation spaces 112 one by one. The partitions 16 are installed at the top of the corresponding installation space 112 and are located above the switching power supplies 10 installed in the corresponding installation space 112 .

[0094] The partition 16 is in a plate-like structure and is flexible and elastic. In this embodiment, the partition 16 is preferably made of a rubber material with poor thermal conductivity; since the rubber material with poor thermal conductivity is a common prior art, no further limitation is made on the material.

[0095] Reference Figure 4 and Figure 6 , both ends of the partition 16 in the length direction have two connecting parts 161, and the two connecting parts 161 are respectively close to the two sides in the width direction of the partition 16; the cabinet body 11 has two grooves 114 adapted to the connecting parts 161 on the two side walls in the length direction of the installation space 112, and the grooves 114 are opened along the width direction of the cabinet body 11; the connecting parts 161 can slide along the corresponding grooves 114, and the partition 16 can be driven to bend and deform during the sliding process of the connecting parts 161.

[0096] The cabinet 11 is also provided with two elastic members 17 on both side walls in the length direction of the plurality of installation spaces 112. The number of the elastic members 17 is equal to and corresponds to the number of the grooves 114, and the elastic members 17 are installed in the corresponding grooves 114. The elastic members 17 are located in the grooves 114 on the side of the adjacent connection portion 161 close to the adjacent opening in the corresponding installation space 112. The two ends of the elastic member 17 are respectively fixedly connected to the corresponding connection portion 161 and the groove wall on the side of the adjacent opening in the corresponding installation space 112, and have a tendency to drive the corresponding connection portion 161 to slide toward the center of the corresponding installation space 112. In this embodiment, the elastic member 17 is preferably a compression spring.

[0097] Reference Figure 5 and Figure 6 When the partition 16 is only subjected to the external force of the four elastic members 17, the four elastic members 17 can drive the corresponding connecting portion 161 to slide toward the center of the corresponding installation space 112 to the extreme position (contacting and abutting against the side groove wall of the corresponding groove 114 close to the installation space 112), and the partition 16 will be in an upwardly convex bending state with the maximum bending degree, and the top of the partition 16 can maintain contact and abutment with the adjacent installation plate 12 above it, and exert a vertical upward force on the installation plate 12.

[0098] Reference Figure 3 and Figure 4 The cover plate 13 has a contact portion 133 on one side of the cover plate 13 away from the clearance groove 131 in the thickness direction thereof for contacting and abutting against the partition plate 16, and the contact portion 133 extends outwardly in a direction parallel to the thickness of the corresponding cover plate 13. In this embodiment, the contact portion 133 is preferably a rectangular plate-shaped structure, and the length of the contact portion 133 is equal to the length of the installation space 112.

[0099] Reference Figure 4 and Figure 6 When the two cover plates 13 installed on the same mounting plate 12 are rotated to cover the openings of the corresponding mounting spaces 112, the abutting portions 133 on the two cover plates 13 enter the corresponding mounting spaces 112, contact and abut against the partition plates 16 located in the corresponding mounting spaces 112, and apply symmetrical forces of the same magnitude to the partition plates 16; at this time, the partition plates 16 will be deformed by the forces of the two abutting portions 133, so that the original upward bending degree is reduced, and at the same time, the corresponding four sliding members will overcome the action of the corresponding elastic members 17 along the grooves 114. Slide with force so that the partition 16 can maintain a distance from the adjacent installation plate 12 above it; at this time, the two abutting parts 133 and the partition 16 can jointly separate the corresponding installation space 112 into two upper and lower spaces, and the temperature control module 8 and the humidity control module 9 can control the temperature and humidity in the space below, while the space formed above can effectively reduce the influence of the temperature and humidity of the space below on the temperature and humidity of the installation space 112 above it, thereby facilitating different switching power supplies 10 to simulate different temperature and humidity environments in different installation spaces 112 for aging tests.

[0100] The implementation principle of a batch aging device for switching power supplies in the embodiment of the present application is as follows:

[0101] After the two cover plates 13 corresponding to the same installation space 112 are rotated to the state of covering the opening of the corresponding installation space 112, the staff can adjust the ventilation effect of the installation space 112 at this time while locking the position of the cover plates 13; thereafter, the staff can also control the temperature control module 8 and the humidity control module 9 through the control module 2, so as to control the temperature and humidity inside the installation space 112 which is sealed to a certain extent at this time; so that a large number of switching power supplies 10 can be subjected to aging tests in a simulated actual use environment, thereby further improving the accuracy of the aging test results.

[0102] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
