[0042] In the present invention, the anti-misopening mechanism includes a card block 3 fixed to the door 2, a card groove 10 provided on the outer wall of the temperature test chamber 1 and an adjusting block 8 slidably arranged on the inner bottom surface of the temperature test chamber 1, a fixing hole is provided in the card block 3, a fixing rod 9 matching the fixing hole is provided on the adjusting block 8, a strip opening 27 is provided on the adjusting block 8, a cylinder 19 is slidably provided in the strip opening 27, a strip opening 1 26 matching the cylinder 19 is provided on the bottom surface of the strip plate 5, and the cylinder 19 is slidably arranged with the strip opening 1 26, an adjusting member 7 matching the cylinder 19 is provided on the inner bottom surface of the temperature test chamber 1, and through the use of the adjusting member 7, it is convenient to insert the fixing rod 9 into the fixing hole or separate the fixing rod 9 from the fixing hole, thereby realizing the anti-misopening of the door 2, and further facilitating the aging detection of the charger.

[0043] In the present invention, the adjustment part 7 includes a disengagement groove 701 provided on the inner bottom surface of the temperature test chamber 1, and an unlocking groove 702 is provided at an angle at one end of the disengagement groove 701, and a straight groove 703 is provided at one end of the unlocking groove 702; wherein, when the cylinder 19 moves in the disengagement groove 701, at this time, the plug is inserted into the socket 31 or the plug is separated from the socket 31; and when the cylinder 19 moves in the unlocking groove 702, at this time, the fixing rod 9 is inserted into the fixing hole or moved out of the fixing hole; and when the cylinder 19 slides in the straight groove 703, at this time, the aging test frame 12 is pushed out.

[0044] In the present invention, the fixing mechanism includes an extrusion plate 23 slidably disposed in the mounting groove 22 , a plurality of extrusion springs 24 are disposed between the extrusion plate 23 and the mounting groove 22 , and a limit plate is fixed to an edge of one end of the mounting groove 22 .

[0045] Working principle: When the present invention is in use, the servo motor 4 is first started, and the output shaft of the servo motor 4 is controlled to rotate in the forward direction. The rotation of the output shaft of the servo motor 4 drives the long screw rod 13 to rotate, and then the threaded sleeve 18 moves toward the position of the door 2, thereby driving the strip plate 5 and the strip frame 14 to move. The movement of the strip frame 14 is divided into two situations:

[0046] Case 1: Under the action of the third extrusion spring 28, the movable block 29 moves synchronously with the second connecting rod 30 and the connecting frame 25, thereby driving the telescopic plate 17 to move, thereby driving the various rectangular plates 16 to move, and realizing the separation of the plug and the socket 31;

[0047] The threaded sleeve 18 drives the cylinder 19 to move while moving. When the plug is separated from the socket 31, the cylinder 19 moves from one end of the disengagement groove 701 to the intersection of the unlocking groove 702 and the disengagement groove 701. As the bar frame 14 continues to move, the cylinder 19 moves along the unlocking groove 702, thereby driving the adjustment block 8 to move, thereby driving the fixing rod 9 to move. When the cylinder 19 moves to the intersection of the unlocking groove 702 and the straight groove 703, the fixing rod 9 is separated from the fixing hole on the card block 3, thereby releasing the fixation of the card block 3.

[0048] At the same time, the telescopic plate 17 moves to the other end of the rectangular opening 20, and the bar frame 14 contacts the baffle 6; at the same time, the movable end of the micro electric push rod 2 38 extends to drive the limit rod 39 to move, so that the limit rod 39 is inserted into the limit hole on the telescopic plate 17, thereby fixing the telescopic plate 17 so that the rectangular plate 16 moves with the aging test frame 12; then the manual box door 2 is opened;

[0049] Case 2: As the bar frame 14 continues to move, the baffle 6 is driven to move, thereby driving the aging test frame 12 to move. Then, under the action of the limit rod 39, the rectangular plate 16 moves synchronously with the aging test frame 12. When the cylinder 19 moves to the other end of the straight groove 703, the aging test frame 12 is completely moved out of the temperature test chamber 1, and the servo motor 4 is stopped.

[0050] Then install the charger between the mounting groove 22 and the extrusion plate 23. The charger is installed by squeezing the extrusion plate 23 and the mounting groove 22. Then, pass the charger plug through the bottom of the rectangular plate 16 and place the plug between the two fixing plates 34. Then, turn the handle 33. The rotation of the handle 33 drives the fixing plates 34 to move relative to each other, thereby fixing the plug. Install each charger on the aging test rack 12 in the above manner.

[0051] Then control the servo motor 4 to make the output shaft of the servo motor 4 rotate in the opposite direction. Under the cooperation of the magnet 1 40 and the magnet 2, the aging test frame 12 is moved into the temperature test chamber 1 along with the bar frame 14. When the cylinder 19 moves to the end of the unlocking groove 702, the aging test frame 12 is completely moved into the temperature test chamber 1. Then close the door 2 to make the card block 3 engage in the card slot 10. Then the movable end of the micro electric push rod 2 38 contracts and drives the limit rod 39 to move into the rectangular cavity, releasing the fixation of the telescopic plate 17. Then The telescopic plate 17 will not reset under the action of the squeezing spring 3 28; as the bar frame 14 continues to reset, the magnet 1 40 and the magnet 2 are separated; and at this time, the cylinder 19 moves along the unlocking slot 702, thereby driving the adjustment block 8 to move, so that the fixing rod 9 is inserted into the fixing hole on the clamping block 3, thereby preventing the door 2 from opening by mistake; finally, as the bar frame 14 continues to move, the cylinder 19 moves into the disengagement slot 701. At this time, under the action of the squeezing spring 1 21, the plug is inserted into the socket 31, and the charger is powered on;

[0052] Among them, when testing the aging of the charger, there are two situations:

[0053] Case 1: Aging test of the charger in a high temperature environment: Specifically, adjust the temperature of the temperature test chamber 1 to be between 40℃ and 60℃, and then keep the charger charging for 24 hours;

[0054] Case 2: Aging test of the charger in a low-temperature environment: Specifically, adjust the temperature of the temperature test chamber 1 to be between -20°C and -40°C, and then allow the charger to charge continuously for 24 hours;

[0055] The above two scenarios can simulate the charger's usage in different seasons and environments, verifying its adaptability and reliability under extreme temperature conditions. In the high-temperature aging test, attention should be paid to the charger's heat dissipation performance and the impact of high temperature on the performance of electronic components. The low-temperature aging test mainly examines whether the charger can start and operate normally in low temperatures, and whether there will be any performance degradation or damage.

[0056] During the plug-in and unplug-out detection of the charger, the servo motor 4 is controlled to make the cylinder 19 move back and forth in the disengagement slot 701, thereby making the bar frame 14 move back and forth, so that the plug is inserted into or pulled out of the socket 31, thereby realizing the plug-in and unplug-out detection of the charger; by performing multiple plug-in and unplug operations, the durability of the connector is tested; the number of plug-in and unplugging times is generally set to thousands or even tens of thousands of times, simulating the frequent plug-in and unplugging of the charger in daily use, and observing whether the plug and socket 31 have problems such as looseness, poor contact, wear, etc., to ensure that the charger is reliably connected during long-term use.

[0057] The above description of the embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
