Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a detachable charging gun head. Background Technology

[0002] The charging gun is a key piece of equipment for charging electric vehicles. As the interface connecting the charging station (or power socket) and the electric vehicle battery, it is responsible for the transmission and safety control of electrical energy. Based on the different charging methods, charging guns are mainly divided into two categories: AC charging guns and DC charging guns, which differ in structure, function, and application scenarios.

[0003] The charging gun's nozzle is used to connect to the car's charging port. It contains pins for connecting wires. Therefore, the charging gun is subject to impact during plugging and unplugging, and it generates heat during charging. Consequently, its outer surface is prone to aging and damage, requiring regular maintenance and replacement.

[0004] However, in the prior art, the various components of the gun head are fixed with screws, making it inconvenient to disassemble and replace them. In order to solve the shortcomings of the prior art in terms of inconvenience in disassembling and replacing the gun head, this application sets up components such as positioning clamps and clips, so that the outer shell and positioning blocks can be fixed to each other without the use of screws. This allows the gun head to be disassembled or installed without the use of tools, thereby improving maintenance efficiency. Therefore, a new solution is needed to solve this problem.

[0025] Please see Figure 1 , 2 3, 4, 5, 6, This utility model discloses a detachable charging gun head, comprising a housing 1, a first retaining ring 2 fixedly connected to the outer surface of the housing 1, a positioning block 3 provided on one side of the housing 1, a second retaining ring 4 fixedly connected to the outer surface of the positioning block 3, a positioning clamp 5 provided on both sides of the positioning block 3, two clamps 6 provided at the bottom of the housing 1, each clamp 6 having a slot 7 inside, a positioning shell 8 fixedly connected to the outer surface of the housing 1, and the two clamps 6 rotatably connected, the outer surface of the first retaining ring 2 having two first positioning holes 9, the outer surface of the second retaining ring 4 having two second positioning holes 10, the outer surface of the housing 1 having corresponding pin holes for the corresponding live wire, neutral wire, ground wire, PP wire, and CP wire, respectively, the positioning block 3 being a detachable and assembleable three-in-one structure for connecting the live wire, neutral wire, ground wire, PP wire, and The pins of the CP line are clamped and fixed. The first retaining ring 2 and the second retaining ring 4 correspond to each other. The outer diameter of the positioning clamp 5 matches the inner diameter of the outer shell 1. The positioning clamp 5 is used to fix the positioning block 3 after it is closed. Each first positioning port 9 corresponds to a second positioning port 10. The outer diameter and inner diameter of the slot 7 correspond to the first retaining ring 2 and the second retaining ring 4. The width of the slot 7 corresponds to the sum of the thicknesses of the first retaining ring 2 and the second retaining ring 4. The positioning block 3 is disassembled and each pin is installed. The positioning block 3 is closed and the two positioning clamps 5 are clamped on the outer surface of the positioning block 3. The positioning clamp 5 is placed inside the outer shell 1 so that the first retaining ring 2 and the second retaining ring 4 are tightly attached to each other. The clamp 6 is used to fix the first retaining ring 2 and the second retaining ring 4 so that the first retaining ring 2 and the second retaining ring 4 are both inserted into the slot 7, thus completing the fixation of the positioning block 3 and the outer shell 1.

[0026] Each positioning hoop 5 has a positioning ring 11 fixedly connected inside. The outer surface of the positioning ring 11 has two positioning grooves 12. The positioning ring 11 corresponds to the positioning grooves 12. When the positioning hoop 5 fixes the positioning block 3, the positioning ring 11 enters the interior of the positioning groove 12, thereby limiting the positioning hoop 5 and preventing the positioning hoop 5 from deflecting from the positioning block 3.

[0027] Two fixing blocks 13 are fixedly connected to the outer surface of each positioning hoop 5. There are two fixing grooves 14 on the inner wall of the outer shell 1. Each fixing groove 14 corresponds to two fixing blocks 13. When the positioning hoop 5 enters the interior of the outer shell 1, the fixing blocks 13 are inserted into the corresponding fixing grooves 14, thereby preventing the positioning hoop 5 from deflecting from the outer shell 1.

[0028] Each clamp 6 has a locking hole 15 on its outer surface, and a locking block 16 is slidably connected inside the positioning shell 8. The locking hole 15 and the locking block 16 correspond to each other, and the locking block 16 can fix and limit the clamp 6 by inserting into the two locking holes 15.

[0029] Two sliding grooves 17 are provided on the outer surface of the positioning shell 8. A sliding piece 18 is slidably connected to the outer surface of the positioning shell 8. The sliding grooves 17 limit the sliding piece 18. The sliding piece 18 is fixedly connected to the locking block 16 through the sliding grooves 17. The sliding piece 18 is used to drive the locking block 16 to slide.

[0030] A fixing ring 19 is fixedly connected to the outer surface of the outer shell 1. The fixing ring 19 is fixedly connected to the positioning shell 8. The outer diameter and thickness of the fixing ring 19 and the clamp 6 are equal. The fixing ring 19 and the clamp 6 are used to engage the outer shell 1 with the inside of the charging gun body, thereby realizing the installation of the gun head and the gun body.

[0031] A spring 20 is installed inside the positioning shell 8. One end of the spring 20 contacts the outer surface of the locking block 16, and the other end of the spring 20 contacts the outer surface of the fixing ring 19. When the slider 18 is manually slid, the slider 18 drives the locking block 16 to slide into the positioning shell 8, and the spring 20 is compressed. When the slider 18 is released, the spring 20 pushes the locking block 16 to automatically reset, so that the locking block 16 can be inserted into the locking hole 15 to fix the clamp 6.

[0032] The implementation principle is as follows: Place the completed wiring pin inside the positioning block 3, close the positioning block 3 to fix the pin, install the positioning clamp 5 so that the positioning ring 11 enters the corresponding positioning groove 12 so that the two corresponding fixing blocks 13 fit together, place the positioning clamp 5 and the positioning block 3 inside the outer shell 1, insert each fixing block 13 into the corresponding fixing groove 14 so that the first retaining ring 2 and the second retaining ring 4 fit together, slide the slider 18, the slider 18 drives the retaining block 16 to slide into the positioning shell 8, the spring 20 is compressed, install the clamp 6 so that the first retaining ring 2 and the second retaining ring 4 both enter the corresponding retaining groove 7. At this time, the two retaining holes 15 are aligned with each other, release the slider 18, the spring 20 pushes the retaining block 16 to reset, the retaining block 16 enters the two retaining holes 15 to complete the limiting of the clamp 6.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
