Its main function is to provide power to the electric vehicle and ensure the normal operation of the vehicle. The outer body of the charging gun is divided into a charging gun head and a cable, and the two are connected and fixed by a nut.

However, when fixing the gun head of the charging gun and the cable connection end, nut locking is a key step. The existing technology often adopts the traditional manual locking method. This method is not only time-consuming and labor-intensive, but also has problems such as inconsistent locking torque and human error, which affects the charging effect and safety. The locking device in the existing technology cannot achieve adaptive clamping of nuts of different sizes, resulting in the need to replace different locking components when locking the nuts of different charging guns.

When the charging gun is inserted into the inside of the clamping groove 701, the When the locking member 4 is locked and pressed down, the pressing rod 706 will be pressed against the pressing rod 706, so that the pressing rod 706 drives the clamping bevel 707 to move downward, and the clamping bevel 707 drives the supporting column 705 and the clamping plate 704 to move, and the clamping plate 704 fixes the charging gun again to avoid deviation or shaking during locking.

[0043] As attached Figure 7As shown, a compression spring 413 is fixedly installed on the outer wall of the compensation rod 411, and the compression spring 413 is located inside the guide groove 409. The other end of the compression spring 413 is fixedly connected to the inner wall of the guide groove 409. There are two locking rods 410, and the two locking rods 410 are arranged opposite to each other; a locking bevel 414 is slidably connected to the interior of the locking cylinder 403, and the thickness of the locking bevel 414 increases from top to bottom. The inclined surface end of the locking bevel 414 abuts against the outer wall of one end of the locking rod 410, and a locking spring 415 is fixedly installed on the top of the locking bevel 414. The other end of the locking spring 415 is fixedly connected to the inner top wall of the locking cylinder 403, and a top post 416 is fixedly installed on the bottom of the locking bevel 414.

At the same time, the locking rod 410 can lock different nuts, which is convenient for disassembly after locking. At the same time, the locking of this device can be linked with the descent of the locking box 401.

[0044] As attached Figure 9 As shown, a rotating shaft 601 is fixedly installed at the bottom of the rotating disk 6, and a rotating bevel gear 602 is fixedly installed on the outer wall of the rotating shaft 601; a linkage shaft 603 is rotatably connected to the inner wall of the base 1, and a linkage bevel gear 604 is fixedly installed on the outer wall of one end of the linkage shaft 603, and the linkage bevel gear 604 is meshed with the rotating bevel gear 602, and a linkage gear 605 is unidirectionally driven and connected to the outer wall of the other end of the linkage shaft 603, and the linkage gear 605 is meshed with the driving gear plate 8.

[0045] As attached Figure 10As shown, a through hole 606 is provided inside the linkage shaft 603, and a one-way inclined block 607 is slidably connected inside the through hole 606.

A one-way inclined groove 609 is provided on the inner wall of the linkage gear 605, and the one-way inclined groove 609 matches the one-way inclined block 607; when the locking box 401 of the present device descends and drives the driving gear plate 8 to displace, the driving gear plate 8 will not drive the linkage shaft 603 to rotate. At this time, the inclined surface of the one-way inclined block 607 is opposite to the inclined surface of the one-way inclined groove 609, and the rotation of the linkage gear 605 will not drive The linkage shaft 603 rotates. At this time, in order to avoid the rotation of the rotating disk 6 during locking, it can ensure that the rotating disk 6 is in a stable state during locking to prevent the locking deviation. When the locking box 401 moves upward for reset, the one-way inclined block 607 is extended under the action of the compression spring 608. At this time, the straight surface of the one-way inclined block 607 is opposite to the straight surface of the one-way inclined groove 609, so that when the linkage gear 605 is driven by the driven tooth plate 8 to rotate, the linkage gear 605 will drive the linkage shaft 603 to rotate, and then the linkage shaft 603 drives the rotating disk 6 to replace the charging gun to be locked, so that the device can automatically replace the locked charging gun, and at the same time, the replacement is linked to the action of the locking box 401.

[0046] As attached Figure 11 As shown, the upper part of the driving gear plate 8 is a smooth plate, and the meshing teeth 801 are fixedly installed on the outer wall of the driving gear plate 8. The inner part of the driving gear plate 8 is slidably connected to the compensation gear plate 8. The outer wall of the compensation gear plate 802 is provided with compensation teeth 803. The compensation teeth 803 are staggered with the meshing teeth 801, and the number of compensation teeth 803 is two. When the device needs to control the number of teeth on the outer wall of the driving gear plate 8, the compensation gear plate 802 can be adjusted to move to achieve automatic adjustment of the number of teeth. When the driving gear plate 8 of the device drives the linkage gear 605 to rotate for a long time, in order to avoid the phenomenon of rotation difference, the device can compensate through the compensation gear plate 802 so that the two can maintain the same rotation. The resetting of the driving gear plate 8 can drive the rotating disk 6 to be replaced. At the same time, the upper part of the driving gear plate 8 of the device is set as a smooth plate, which can prevent the rotating disk 6 from starting to rotate when the driving gear plate 8 starts to reset, and prevents the rotating disk 6 from rotating when the locking cylinder 403 does not leave the fixed box 7.
