[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] See also Figures 1 to 5 By setting the guide rail 301 and the pressure block 304, the charger 400 to be tested can move along the layout direction of the guide rail 301 driven by the pressure block 304, thereby realizing the automatic plugging and unplugging operation of the charger, and using the oblique interpolation method to perfectly simulate the current oblique plugging and unplugging method of the charger, which has good use value and application prospects.

[0022] Specifically, if Figures 1 to 5 As shown in the figure, an aging test system suitable for a power charger of the present invention comprises a test cabinet 100; at least one frame structure 200 is arranged in the horizontal direction in the test cabinet 100, and the frame structure 200 comprises a test frame 201, and an inclined surface is formed on the side of the test frame 201 away from the inside of the test cabinet 100, and at least one test socket is provided on the inclined surface; and corresponding to the test socket, at least one automatic plug-in structure 300 is arranged on the frame structure 200, which is used to plug the charger 400 to be tested into the test socket; the automatic plug-in structure 300 comprises Two guide rails 301, the guide rails 301 include a horizontal section and an inclined section which are connected in sequence; the inclination of the inclined section matches the inclined surface, and one end of the inclined section is connected to the test frame 201; and a driving motor 302 is arranged between the two horizontal sections, a conveyor belt is arranged on the side where the two guide rails 301 are away from each other, the driving motor 302 is connected to the two conveyor belts, and connecting members 303 are arranged on the two conveyor belts, and a pressure block 304 is arranged on the side where the two connecting members 303 are close to each other, and a transmission channel for the charger 400 to be tested is formed between the two pressure blocks 304 and the two guide rails 301.

[0023] In the actual design process, it is preferred that the angle between the inclined section and the horizontal section is 150°. Figure 1 As shown in Figure 1 From the perspective of the test interface 202, the direction of the test interface 202 is obliquely downward. Of course, it can also be set obliquely, so that this setting form perfectly simulates the current oblique plug-in charging method and improves the diversity of test samples.

[0024] When in use, the operator only needs to place the electric test charger between the two guide rails 301. Since the guide rail 301 adopts an "L"-shaped design, the charger 400 to be tested can always remain stable during the subsequent transmission process. At the same time, combined with the design of the upper pressing block 304, the pressing block 304 drives the charger 400 to be tested to move under the drive of the conveyor belt, which can ensure the stability of the charger 400 to be tested during the transportation process and the subsequent stability during the test process.

[0025] In addition, an electrical module is also provided in the test cabinet 100 , which is electrically connected to the test interface 202 and is used to detect the charger after the charger 400 to be tested is inserted into the test interface.

[0026] Furthermore, in order to improve the stable connection between the charger 400 to be tested and the test interface 202, a linear module 308 is provided on the inclined section of the two guide rails 301 and corresponding to one side of the test interface 202; a second cylinder 309 is provided on both linear modules 308, and a clamping block is provided at the telescopic end of the second cylinder 309.

[0027] During actual use, when the charger 400 to be tested moves to the specified position, the second cylinder 309 drives the two clamping blocks to clamp the charger 400 to be tested, and drives it to move through the linear module 308, and cooperates with the full push of the push block at the tail of the charger, so that the charger 400 to be tested can be inserted into the test interface 202, and the stability of the two after connection is guaranteed.

[0028] Preferably, an infrared emitting sensor and an infrared receiving sensor are respectively provided on the two linear modules 308, and the two are electrically connected. When the charger 400 to be tested is transmitted between the two linear modules 308, and the laser emitted by the infrared emitting module cannot be received by the infrared receiving sensor, the second cylinder 309 and the linear module 308 start to work to clamp and transport the charger 400 to be tested.

[0029] In more detail, Figure 5As shown in the figure, the aging test system of the present invention is provided with a guide assembly 310 at the connection between the inclined section and the straight section of the guide rail 301, which is used to assist the charger in changing its transmission posture. The guide assembly 310 includes an assembly plate 3101 arranged between the two guide rails 301, and one end of the assembly plate 3101 is connected to the test frame 201 through a mounting frame 3104, and a third cylinder 3102 is installed on the assembly plate 3101, and a guide plate 3103 is provided on the telescopic section of the third cylinder 3102, and the guide plate 3103 moves vertically at the connection between the inclined section and the straight section of the guide rail 301.

[0030] Furthermore, the aging test system of the present invention is provided with a conductive member 307 corresponding to the charger 400 to be tested, the conductive member 307 is assembled between the two pressing blocks 304, and is electrically connected to the test interface 202. At the same time, a connecting plate 305 is preferably provided between the two pressing blocks 304, a first cylinder 306 is provided on the connecting plate 305, and the conductive member 307 is installed on the telescopic end of the first cylinder 306.

[0031] During actual use, when the charger 400 to be tested is placed between the two guide rails 301, the first cylinder 306 controls the conductive part 307 to be inserted into the socket on the back of the charger, and the other end can be inserted into the test interface 202. The conductive part 307 integrated in the automatic plug-in assembly replaces the traditional method of using wires and cables to achieve electrical connection, simplifies the aging test process, greatly improves the test efficiency, perfectly replaces the traditional manual plug-in method, and ensures the safety of the process.

[0032] In addition, an indicator light 203 is provided corresponding to the test socket, which is assembled on the test frame 201 and connected to the test socket. An adjustment knob 204 is provided corresponding to each test interface 202 .

[0033] Further, Figure 1 As shown in the figure, it is preferred that there are multiple test sockets, and the multiple test interfaces are arranged horizontally along the test frame 201; and corresponding to the multiple test sockets, there are also multiple automatic plug-in structures 300. At the same time, there are multiple frame structures 200, and the multiple frame structures 200 are spaced apart along the height direction of the cabinet.

[0034] On this basis, the present invention also provides an aging test method applicable to a power charger, which is implemented using the aging test system in the above preferred embodiment. The method comprises the following steps: Place the charger 400 to be tested between the two guide rails 301; turn on the drive motor 302 to drive the conveyor belt to move, and drive the connecting piece 303 and the pressing block 304 to move; and drive the charger 400 to be tested to move along the layout direction of the guide rails 301 through the connecting piece 303 and the pressing block 304; until the charger 400 to be tested is inserted into the test interface 202.
