DETAILED DESCRIPTION

[0032] The utility model will be described below in combination with specific implementation.

[0033] Example one, as Figures 1 to 4 The automatic gun locking structure of the charging converter includes the converter main body 1, the converter main body 1 is provided with the first cavity 11 for the charging gun 7 insertion, the second cavity 12 for the automobile charging seat of new energy automobile insertion, the first cavity 11, the second cavity 12 is located at both ends of the converter main body 1.It needs to be explained that the charging converter can be used between NACS standard charging gun and American standard automobile charging conversion.

[0034] Among them, as Figures 2 to 4 The automatic gun locking structure of the charging converter includes the movable sliding needle 2, the sliding needle spring 3 installed on the movable sliding needle 2, the movable sliding needle 2 is slidably installed on the converter main body 1, and the movable sliding needle 2 is provided with the sliding rod part 21, and the sliding needle spring 3 is located on the opposite side of the sliding rod part 21.

[0035] Further, as Figures 1 to 3As shown, the outer surface of the converter body 1 is provided with a key cavity 13, and the key cavity 13 is provided with a movable key 4. The middle part of the movable key 4 is hingedly connected to the converter body 1 through a pivot 5. The end of the movable key 4 towards the first cavity 11 is a first end 41, and the end of the movable key 4 towards the second cavity 12 is a second end 42.

[0036] Further, as shown, Figures 2 to 4 The first end 41 of the movable key 4 is provided with a charging gun lock catch 43, and the converter body 1 is provided with a lock catch through hole 14 which is in communication with the first cavity 11 and the key cavity 13 and through which the charging gun lock catch 43 passes. The key cavity 13 is provided with a key spring 6 which outwardly abuts against the second end 42 of the movable key 4.

[0037] In addition, as shown, Figures 2 to 4 The movable slide pin 2 is located between the key cavity 13 and the second cavity 12, and the slide rod part 21 of the movable slide pin 2 extends into the second cavity 12. The movable slide pin 2 is provided with a blocking rod part 22 on the opposite side of the slide rod part 21, which can extend into the key cavity 13.

[0038] During the use of the automatic locking gun structure of the charging converter of the first embodiment, during the charging operation, the charging gun 7 is first inserted into the first cavity 11 of the converter body 1. When the charging gun 7 is inserted into place, the charging gun lock 43 of the movable button 4 is buckled into the buckle groove 71 of the charging gun 7 through the lock through hole 14. The elastic force of the button spring 6 keeps the charging gun lock 43 in the buckle groove 71, thereby locking the charging gun 7 in the first cavity 11 of the converter body 1; then the converter body 1 is aligned with the car charging seat of the new energy vehicle, and the car charging seat is inserted into the second cavity 12 of the converter body 1. During this process, the car charging seat will push against the sliding rod portion 21 of the movable sliding needle 2 and make the entire movable sliding needle 2 move toward the button cavity 13 side, thereby making the blocking rod portion 22 of the movable sliding needle 2 extend into the button cavity 13, and the sliding needle spring 3 is compressed. When the car charging seat is inserted into place, the blocking rod portion 22 of the movable sliding needle 2 moves to the movable The inner side of the second end portion 42 of the button 4 cannot be pressed due to the blocking effect of the blocking rod portion 22, that is, the charging gun lock 43 of the first end portion 41 of the movable button 4 keeps the charging gun 7 locked; when charging is completed and the charging gun 7 is unlocked, the converter body 1 and the charging gun 7 move synchronously and retreat from the car charging seat of the new energy vehicle. During this process, the return elastic force of the sliding needle spring 3 causes the entire movable sliding needle 2 to move toward the second cavity 12 side, and the sliding rod portion 21 of the movable sliding needle 2 re-enters the second cavity 12, and the blocking rod portion 22 of the movable sliding needle 2 gradually retreats from the blocking position. After the blocking rod portion 22 completely retreats from the blocking position, the second end portion 42 of the movable button 4 is pressed and the first end portion 41 is tilted outward, so that the charging gun lock 43 retreats from the buckle groove 71 of the charging gun 7, the charging gun 7 is unlocked and the charging gun 7 can be pulled out at will, thereby effectively avoiding the risk of pulling out the gun with power during high-voltage charging.

[0039] It should be emphasized that, compared with the prior art, the automatic gun locking structure of the present embodiment 1 includes a movable sliding needle 2, a movable button 4, a sliding needle spring 3, a button spring 6 and a charging gun lock 43, and the overall structure is simpler; in addition, compared with the prior art, the automatic gun locking structure of the present embodiment 1 does not have contact wear during use, and has better stability and reliability.
