[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4 The present invention provides a dustproof and waterproof charging gun head, comprising a gun head body 1 with a connection port 7 provided at the end of the gun head body 1, the connection port 7 being connected to a detachable protective cover 2, the outer side of the protective cover 2 being connected to a connection rope, the end of the connection rope being connected to the gun head body 1, and being prevented from being separated from the gun head body 1 when the protective cover 2 is opened. The gun head body 1 is connected to a positioning mechanism for positioning the protective cover 2, the positioning mechanism comprising a plurality of guide seats 6, a plurality of lifting plates 15, and a plurality of springs 13. Three guide seats 6, lifting plates 15, and springs 13 may be provided, and the adjacent angles of the corresponding structures are 120°. The guide seat 6 is used to guide the lifting plate 15, the spring 13 is used to drive the lifting plate 15 to move in a direction close to the protective cover 2, and the lifting plate 15 is connected to a driving mechanism for driving the lifting plate 15 to rise and fall.

[0021] When the charging gun head is not in use, the protective cover 2 is docked with the connecting port 7, the protective cover 2 is moved forward, and the connecting end 3 slides relative to the inclined surface 16, the lifting plate 15 can be lifted, and the spring 13 is compressed until the connecting end 3 is connected to the sealing groove 9. The compressed spring 13 drives the lifting plate 15 to return to its original position, so that the bottom end of the side of the lifting plate 15 is connected to the connecting end 3, so that the protective cover 2 can be quickly installed. At the same time, the protective cover 2 is pressed on the sealing inclined surface 8, and the use of the sealing groove 9 is combined to achieve a double sealing effect, which has a good dust and water proof purpose for the connecting port 7.

[0022] The positioning mechanism also includes multiple guide grooves and multiple inclined surfaces 16. The guide grooves are provided in the guide seat 6, and the lifting plate 15 is slidably connected to the guide grooves. The inclined surfaces 16 are provided at the ends of the lifting plate 15. The inclined surfaces 16 are smooth surfaces to reduce contact friction. The guide grooves provide good guidance for the lifting plate 15, ensuring stable lifting and lowering.

[0023] The spring 13 is located in the guide groove, and both ends of the spring 13 are connected to the guide seat 6 and the lifting plate 15 .

[0024] The drive mechanism includes a movable seat 5, multiple sliding blocks 11, multiple connecting plates 12, multiple sliding posts 14, and an arcuate plate 4. The sliding blocks 11 are used to guide the movable seat 5. The arcuate plate 4 is connected to the multiple sliding blocks 11. The ends of the connecting plates 12 are connected to the sliding blocks 11 and the sliding posts 14. The sliding posts 14 are slidably connected to the inclined holes 17 set in the lifting plate 15. Applying a thrust to the movable seat 5 in the X direction can drive the three connecting plates 12 to move synchronously. The connecting plates 12 apply a pulling force to the sliding posts 14, causing them to slide in the inclined holes 17, which can drive the lifting plate 15 to move upward. At this time, the spring 13 is compressed until the lifting plate 15 is separated from the connecting end 3, thereby loosening the protective cover 2 and facilitating separation from the connecting port 7.

[0025] A plurality of slide grooves 10 are provided on the surface of the gun head body 1 , and the sliding blocks 11 are slidably connected to the corresponding slide grooves 10 . The sliding blocks 11 play a good guiding role in the movement of the moving seat 5 and the connecting plate 12 .

[0026] A rectangular hole 18 is provided on the side of the lifting plate 15 , the connecting plate 12 passes through the rectangular hole 18 , and the rectangular hole 18 is connected to the inclined hole 17 .

[0027] A sealing groove 9 is provided at the end of the gun head body 1, which matches the connecting end 3 connected to the end of the protective cover 2. A sealing gasket is provided in the sealing groove 9. When the connecting end 3 is connected to the sealing groove 9, the sealing performance of the connection between the two can be improved.

[0028] A sealing bevel 8 is provided at the end of the connection port 7, which matches the sealing connection surface on the inner side of the protective cover 2. When the connection end 3 is connected to the sealing groove 9, the inner side of the protective cover 2 is pressed against the sealing bevel 8 to achieve a good seal for the connection port 7 and prevent the invasion of external dust and water stains.

[0029] Working principle: When using the gun head body 1, the protective cover 2 is in the open state, so that the connection port 7 is docked with the car charging port to achieve the charging purpose. When charging is completed, the protective cover 2 is docked with the connection port 7, and the protective cover 2 is driven forward. The connection end 3 and the inclined surface 16 slide relative to each other, and the lifting plate 15 can be lifted, and the spring 13 is gradually compressed. Until the connection end 3 is connected to the sealing groove 9, the compressed spring 13 drives the lifting plate 15 back to its original position, so that the side bottom end of the lifting plate 15 is connected to the connection end 3, realizing the limit of the connection end 3. At the same time, the protective cover 2 is pressed on the sealing inclined surface 8, and then cooperated with the use of the sealing groove 9 to achieve a double sealing effect, which has a good dust and water proof effect on the connection port 7. When the protective cover 2 needs to be disassembled, a thrust is applied to the movable seat 5, and in conjunction with the use of the curved plate 4, the three connecting plates 12 can be synchronously driven to move, so that the sliding column 14 slides in the inclined hole 17, and the three lifting plates 15 can be driven to rise synchronously until the lifting plate 15 is separated from the connecting end 3, thereby loosening the connecting end 3, thereby facilitating the separation of the protective cover 2 from the connecting port 7, and the operation is simple and convenient.
