The locking component is arranged in the sliding component, and is used to limit the sliding component.

[0030] In one embodiment, Figure 8 As shown, the sliding assembly includes a push block 9, a friction block 11, and a connecting block 18. A push block groove is provided on the outer wall of the charging box 1, and a push block 9 is slidably connected to the inner wall of the push block groove. The side wall of the push block 9 located outside the charging box 1 is fixedly connected to the friction block 11, and the side wall of the push block 9 located inside the charging box 1 is fixedly connected to the connecting block 18. The side wall of the connecting block 18 away from the push block 9 is fixedly connected to the charging head body 2. A connecting block groove is provided on the inner wall of the charging box 1, and the connecting block 18 is slidably connected to the inner wall of the connecting block groove. The movement of the push block 9 drives the connecting block 18 to move, and the connecting block 18 drives the charging head body 2 to move outside the charging box 1.

[0031] In one embodiment, Figure 3 and Figure 4 As shown, the side wall of the charging head body 2 is provided with a protrusion, and the protrusion of the charging head body 2 is slidably connected with the inner side wall of the charging box 1. The protrusion can limit the charging head body 2.

[0032] In one embodiment, Figure 8 As shown, the locking assembly includes a resistance block 14, and two resistance block grooves are provided on the side wall of the push block 9. The resistance block 14 is slidably connected to the inner side wall of the resistance block groove.

The side wall of the resistance block 14 located in the resistance block groove is fixedly connected to the second pull rope 15. One end of the second pull rope 15 away from the resistance block 14 extends through the second pull rope cavity 16 to the lifting block groove and is fixedly connected to the side wall of the lifting block 13. The inner side wall of the second pull rope cavity 16 is rotatably connected to a fourth fixed pulley 17 through a bearing, and the second pull rope 15 bypasses the fourth fixed pulley 17. Use your fingers to press the pressing block 12 and push the friction block 11. The pressing block 12 drives the lifting block 13 to descend. The lifting block 13 descends and pulls the second pull rope 15. The second pull rope 15 drives the resistance block 14 to enter the resistance block groove, so that the resistance block 14 no longer abuts against the push block groove, the locking state is released, and the push block 9 can be pushed to move.

[0034] In one embodiment, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the unfolding assembly includes a first rope-drawing cavity 5, a first fixed pulley 6, a second fixed pulley 7, a third fixed pulley 8, and a fifth fixed pulley 19. The inner wall of the charging box 1 is provided with two first rope-drawing cavities 5, a third rope-drawing cavity 21, and a fourth rope-drawing cavity 22. The protection plate groove 4, the first rope-drawing cavity 5, the third rope-drawing cavity 21, and the fourth rope-drawing cavity 22 are connected. A damping spring is fixedly connected between the protection plate 3 and the inner wall of the protection plate groove 4. The side wall of the protection plate 3 located in the protection plate groove 4 is fixedly connected with the first rope-drawing cavity 5. The end of the first rope-drawing cavity 5 away from the protection plate 3 is fixedly connected with the first rope-drawing cavity 5. The first pull rope 10 passes through the protection plate slot 4, the first pull rope cavity 5, the third pull rope cavity 21, the fourth pull rope cavity 22, the connection block slot and extends into the push block slot and is fixedly connected to the side wall of the push block 9. The inner wall of the first pull rope cavity 5 is rotatably connected to the first fixed pulley 6 through a bearing, the inner wall of the third pull rope cavity 21 is rotatably connected to the second fixed pulley 7 through a bearing, and the inner wall of the fourth pull rope cavity 22 is rotatably connected to the third fixed pulley 8 and the fifth fixed pulley 19 through a bearing. The first pull rope 10 bypasses the first fixed pulley 6, the second fixed pulley 7, the third fixed pulley 8, and the fifth fixed pulley 19 in sequence. During the movement of the push block 9, the first pull rope 10 is pulled. The first pull rope 10 changes the direction of force by bypassing the first fixed pulley 6, the second fixed pulley 7, the third fixed pulley 8, and the fifth fixed pulley 19, so that the first pull rope 10 pulls the two protection plates 3 to both sides and enters the protection plate slot 4, and finally makes the connector of the charging head body 2 exposed outside the charging box 1 and connected to the external socket.

[0035] Example 2

[0036] In one embodiment, Figure 4 As shown, the third fixed pulley 8 is fixedly connected to a limiting block 20, which can prevent the pull rope 10 from deviating too much.

[0037] In one embodiment, Figure 1 and Figure 2 As shown, the side wall of the charging box 1 is provided with chamfers to prevent people from being bumped.

[0038] The above embodiment discloses a retractable charging head. The pressing block 12 is pressed with a finger and the friction block 11 is pushed. The pressing block 12 drives the lifting block 13 to descend. The lifting block 13 descends and pulls the second pull rope 15. The second pull rope 15 drives the resistance block 14 into the resistance block groove, so that the resistance block 14 no longer abuts against the push block groove, and the locking state is released, so that the push block 9 can be pushed to move.

[0039] The push block 9 moves to drive the connecting block 18 to move, and the connecting block 18 drives the charging head body 2 to move out of the charging box 1;

[0040] At the same time, the push block 9 pulls the first pull rope 10 during its movement, and the first pull rope 10 changes the direction of force by passing around the first fixed pulley 6, the second fixed pulley 7, the third fixed pulley 8, and the fifth fixed pulley 19, so that the first pull rope 10 pulls the two protection plates 3 to both sides and enters the protection plate groove 4, and finally makes the connector of the charging head body 2 exposed outside the charging box 1 and connected to the external socket;

[0041] When the connector of the charging head body 2 is located outside the charging box 1, release your finger, and the lifting block 13 is reset by the damping spring. The resistance block 14 is pushed out of the resistance block groove under the action of the damping spring, and the anti-slip rubber pad on the side wall of the resistance block 14 increases the friction force to prevent the push block 9 from moving, thereby completing the locking and fixing of the position of the push block 9;

[0042] When the charging head body 2 is not in use, the pressing block 12 can be pressed to push the friction block 11 in the opposite direction so that the charging head body 2 is retracted into the charging box 1. The protective plate 3 is reset under the action of the damping spring to block the opening of the charging box 1, so that the charging head body 2 is protected in the charging box 1 to prevent the connector of the charging head body 2 from being exposed, damaged by bumps and bends, or adhered to by contaminants, resulting in poor contact and affecting use.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
