[0020] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0021] Example 1: This embodiment provides a technical solution: a charging gun protection device for a new energy charging pile, such as Figures 1-6 As shown, the present invention includes a charging gun 1 , a protective cover assembly 2 and a control shell 3 .

[0022] In the specific implementation, such as Figure 2 As shown, a gun head 4 is provided at one end of the charging gun 1. The charging gun 1 is connected to the charging pile through a line. The charging gun head 4 of the charging gun 1 is connected to the connection terminal of the new energy vehicle to perform the charging operation.

[0023] In the specific implementation, such as Figure 1 and 3 As shown, the protective cover assembly 2 is used to seal and protect the gun head 4. The protective cover assembly 2 includes two half shells 5. The two half shells 5 are mirror-imaged and respectively clamped on both sides of the gun head 4. When the charging gun 1 is not in use, the half shells 5 on both sides form a complete protective cover assembly 2 and cover the outside of the gun head 4, thereby achieving a waterproof and dustproof effect.

[0024] Further, such as Figure 4 As shown, a sealing groove 9 is opened on one of the half shells 5, and a sealing strip 10 corresponding to the sealing groove 9 is bonded to the other half shell 5. Therefore, the sealing strip 10 cooperates with the sealing groove 9 to ensure good sealing between the inside and outside when protecting the gun head 4, thereby improving the protection effect. The cross-sectional area of ​​the sealing groove 9 gradually decreases from the outside to the inside, and the area of ​​the sealing groove 9 gradually shrinks. Therefore, when the two half shells 5 protect the gun head 4, the sealing strip 10 can be accurately stuck in the sealing groove 9, thereby making the sealing process smooth and the protective sealing effect good.

[0025] In the specific implementation, such as Figure 1 、 Figure 3 and4 As shown, the control shell 3 is arranged on the top of the charging gun 1, and the lower part of the control shell 3 is provided with a snap-in groove. The control shell 3 is installed on the charging gun 1 through the snap-in groove. A shell cover 19 is installed on the top of the control shell 3. A half-shell opening and closing control component 6 for controlling the opening and closing of the half-shell 5 is provided in the control shell 3 and the shell cover 19. The opening and closing of the half-shell 5 can be automatically controlled by the half-shell opening and closing control component 6. During the charging process, the control shell 3, the half-shell 5 and the charging gun 1 can still be used as a whole. Therefore, the operation is simple, and there will be no situation where the half-shell 5 is placed separately and lost, and When the half shell 5 is covered to the outside of the gun head 4, it is not inserted by friction, so the wear is small and the service life is long. The half shell opening and closing control component 6 includes a servo motor 601, a driving gear 602, a driven gear 603, two control gears 604, two rotating rods 605 and two connecting rods 606. A receiving groove is provided at the bottom of the shell cover 19, and a placement groove is provided at the top of the shell cover 19. The servo motor 601 is installed in the placement groove, and the driving gear 602 is provided in the receiving groove and the driving gear 602 is installed at the output end of the servo motor 601. The servo motor 601 can drive the driving gear 602 to rotate. The gear 602 rotates, and the driven gear 603 is rotated and mounted on the inner wall of the accommodating groove, and the driven gear 603 is meshed with the driving gear 602. The two control gears 604 are respectively arranged on both sides of the inner wall of the accommodating groove, and the two control gears 604 are respectively meshed with the driving gear 602 and the driven gear 603. Therefore, the driving gear 602 can drive the driven gear 603 and the control gear 604 meshed with it to rotate, and at the same time, the driven gear 603 can drive the other control gear 604 to rotate. At this time, the two driven gears 603 rotate in opposite directions, and the half shells on both sides are The body 5 can rotate in opposite directions at the same time. Control grooves 7 are provided on both sides of the control shell 3. Two rotating rods 605 are respectively installed at the bottom of the two control gears 604 and the bottoms of the two rotating rods 605 are rotatably installed in the control grooves 7. A mounting block 8 is installed at the edge of the semi-shell 5, and a connecting rod 606 is installed between the mounting block 8 and the rotating rod 605. The control gear 604 can drive the rotating rod 605 to rotate, so the rotating rod 605 can drive the mounting block 8 and the semi-shell 5 to rotate through the connecting rod 606, so that the semi-shell 5 can be rotated out from the outside of the gun head 4 to a state where the gun head 4 is exposed.

[0026] Furthermore, the specifications of the driving gear 602 and the driven gear 603 are the same, so the opening and closing angles of the half shells 5 on both sides are always the same, thereby ensuring that the half shells 5 on both sides are matched with high accuracy and have a good protection effect on the gun head 4.

[0027] Furthermore, an extension portion 11 is provided on the rear side of the half shell 5 for wrapping the end of the charging gun 1 , thereby further improving the protection area and stability during use.

[0028] When the protective cover assembly 2 provided in this embodiment protects the gun head 4, the half shells 5 on both sides are as follows Figure 1 As shown, the gun head 4 is covered from both sides, so it can play a waterproof and dustproof effect. When it needs to be used, it is only necessary to control the servo motor 601 to rotate, and the servo motor 601 can drive the driving gear 602 to rotate. The driving gear 602 can drive the driven gear 603 and the control gear 604 meshed with it to rotate. At the same time, the driven gear 603 can drive another control gear 604 to rotate. At this time, the two driven gears 603 rotate in opposite directions, and the half shells 5 on both sides can rotate in opposite directions at the same time. At this time, the state is as follows Figure 5 As shown, the gun head 4 is exposed, the half shell 5 rotates 90 degrees and then turns off the servo motor 601. At this time, the state is as follows: Figure 6 As shown, the half shell 5 is rotated to the rear side of the gun head 4. At this time, the gun head 4 can be connected to the charging connection end of the new energy vehicle to complete charging.

When the semi-shell 5 is opened, it can drive the extrusion piece 16 to rotate, and the extrusion piece 16 can push the extrusion component, so that the gas in the air storage chamber 14 can be squeezed into the sealing bag ring 13. Therefore, the sealing bag ring 13 can expand to greatly improve the sealing between the gun head 4 and the charging connection end of the new energy vehicle, thereby ensuring that the connection between the gun head 4 and the charging connection end of the new energy vehicle is more stable.

[0032] Preferably, the gas injection assembly 18 comprises a control piece 1801, a push rod 1802, a push piece 1803 and a limiting spring 1804, the control piece 1801 and the push piece 1803 are respectively clamped in the trigger cavity 15 and the gas storage cavity 14, a communication hole is arranged between the trigger cavity 15 and the gas storage cavity 14, the push rod 1802 is installed between the control piece 1801 and the push piece 1803 and clamped in the communication hole, and the limiting spring 1804 is sleeved outside the push rod 1802 and installed between the control piece 1801 and the inner wall of the trigger cavity 15. The control piece 1801 can be limited by the limiting spring 1804. As shown in Figure 8 , the limiting spring 1804 is in an extended state, the pressing piece 16 can be rotated to a position in contact with the control piece 1801 when the rotating rod 605 rotates, then the pressing piece 16 can push the control piece 1801, the control piece 1801 can press the limiting spring 1804 and push the push piece 1803 to move through the push rod 1802, the push piece 1803 can push the gas in the gas storage cavity 14 into the sealing capsule ring 13, so that the sealing capsule ring 13 can expand and tightly adhere to the inner wall of the new energy automobile charging connection end, thereby ensuring the stable connection of the gun head 4 and the new energy automobile charging connection end.

[0033] In the embodiment, when the charging gun 1 needs to be used, the servo motor 601 is controlled to rotate, the servo motor 601 can drive the driving gear 602 to rotate, the driving gear 602 can drive the driven gear 603 and the control gear 604 connected with it to rotate, and at the same time, the driven gear 603 can drive the other control gear 604 to rotate. At this time, the two driven gears 603 rotate in opposite directions, and the two half shells 5 can simultaneously rotate in opposite directions. As shown in Figure 5 , the gun head 4 is exposed, and then the gun head 4 is inserted into the new energy automobile charging connection end.
