[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0036] 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 the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Please refer to Figures 1 to 5 , which, by means of the provided guide rail 301 and pressing block 304, enables the charger 400 to be tested to move along the layout direction of the guide rail 301 under the drive of the pressing block 304, thereby realizing the automatic plugging and unplugging operation of the charger, and perfectly simulating the current way of obliquely plugging and unplugging the charger by means of oblique interpolation, having good use value and application prospect.

[0038] Specifically, as Figures 1 to 5As shown in the figure, an aging test system for a power charger according to the present invention includes a test cabinet 100; at least one rack structure 200 is horizontally arranged in the test cabinet 100. The rack structure 200 includes a test rack 201. An inclined surface is formed on the side of the test rack 201 away from the inside of the test cabinet 100, and at least one test socket is provided on the inclined surface; corresponding to the test socket, at least one automatic plugging and unplugging structure 300 is provided on the rack structure 200 for plugging the charger 400 to be tested into the test socket; the automatic plugging and unplugging structure 300 includes two guide rails 301. The guide rails 301 include a horizontal section and an inclined section connected in sequence; and the slope of the inclined section matches the inclined surface, and one end of the inclined section is connected to the test rack 201; 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 in transmission connection with the two conveyor belts, and connecting members 303 are arranged on the two conveyor belts. Pressing blocks 304 are arranged on the sides 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 pressing blocks 304 and the two guide rails 301.

[0039] In the actual design process, it is preferably that the included angle between the inclined section and the horizontal section is 150°, as Figure 1 shown in the figure, so that Figure 1 from the perspective of, the direction of the test interface 202 is obliquely downward. Of course, it can also be set obliquely, so as to perfectly simulate the current obliquely plugging and unplugging charging method through this setting form, and improve the diversity of test samples.

[0040] During use, the operator only needs to place the electrically tested charger between the two guide rails 301. Since the guide rails 301 adopt an "L" - shaped design form, during the subsequent transmission process, the charger 400 to be tested can always remain stable. At the same time, with the design form of the pressing block 304, when the pressing block 304 drives the charger 400 to move under the drive of the conveyor belt, it can ensure the stability of the charger 400 to be tested during the conveying process and during the subsequent test process.

[0041] In addition, an electrical module is also arranged 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.

[0042] Furthermore, in order to improve the stable connection between the charger 400 to be tested and the test interface 202, linear modules 308 are arranged on the inclined sections of the two guide rails 301 and on the side corresponding to the test interface 202; second cylinders 309 are arranged on the two linear modules 308, and clamping blocks are arranged on the telescopic ends of the second cylinders 309.

[0043] During actual use, after the charger 400 to be tested moves to the designated position, the second cylinder 309 drives two clamping blocks to clamp the charger 400 to be tested, and drives its movement through the linear module 308. With the full push of the push block at the tail of the charger, the charger 400 to be tested can be inserted into the test interface 202, and the stability of the two after connection is ensured.

[0044] Preferably, an infrared emission sensor and an infrared reception sensor are respectively arranged 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 emission module cannot be received by the infrared reception sensor, the second cylinder 309 and the linear module 308 start to work to clamp and convey the charger 400 to be tested.

[0045] More specifically, as Figure 5 shown in, in the aging test system of the present invention, a guiding component 310 is arranged at the connection of the inclined section and the linear section of the guide rail 301 for assisting the charger to change its transmission posture. The guiding component 310 includes an assembly plate 3101 arranged between the two guide rails 301, and one end of it is connected to the test rack 201 through a mounting frame 3104. A third cylinder 3102 is installed on the assembly plate 3101, and a guiding plate 3103 is arranged on the telescopic section of the third cylinder 3102. The guiding plate 3103 moves vertically at the connection of the inclined section and the linear section of the guide rail 301.

[0046] Furthermore, in the aging test system of the present invention, a conductive part 307 is arranged corresponding to the charger 400 to be tested. The conductive part 307 is assembled between the two pressing blocks 304 and is electrically connected to the test interface 202. At the same time, preferably, a connecting plate 305 is arranged between the two pressing blocks 304, a first cylinder 306 is arranged on the connecting plate 305, and the conductive part 307 is installed on the telescopic end of the first cylinder 306.

[0047] During actual use, after the charger 400 to be tested is placed between the two guide rails 301, the conductive part 307 is controlled by the first cylinder 306 to be inserted into the socket on the back of the charger, and the other end can be inserted into the test interface 202. Furthermore, the conductive part 307 integrated in the automatic plugging and unplugging component is used to replace the traditional way of realizing electrical connection by using wire cables, simplifying the aging test process, greatly improving the test efficiency, perfectly replacing the traditional manual plugging and unplugging method, and ensuring the safety of the process at the same time.

[0048] In addition, an indicator light 203 is arranged corresponding to the test socket. It is assembled on the test rack 201 and is connected to the test socket point. An adjustment knob 204 is arranged corresponding to each test interface 202.

[0049] Furthermore,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.

[0050] 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:

[0051] 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.

[0053] (2) The aging test system and method for power chargers of the present invention have a simple overall structure and are easy to use. They can not only realize the automatic plugging and unplugging of the charger, but also perfectly simulate the current usage scenario of oblique plugging and unplugging by using the oblique plugging and unplugging method. At the same time, they can perform a secondary squeeze on the charger to be tested to ensure its stability after insertion. They have good use value and application prospects.
