Description

Technical Field

[0001] The invention relates to a portable electric vehicle charging pile, belonging to the field of automobile charging piles. Background Art

[0002] A charging pile is a device that replenishes power for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots.

[0028] See Figure 4 A squeezing switch is provided on the outer surface of the wiring harness box 5 and on the outer surface of the fixing rod 16. The squeezing switch is adapted to the limit member 17. The outer surface of the wiring harness box 5 is also provided with a status indicator light 19 connected to the squeezing switch. Through the design of the squeezing switch and the status indicator light 19, it is possible to judge by the status indicator light 19 whether the limit member 17 drives the limit column 18 to be clamped into the clamping groove 15 and whether the clamping and fixing of the clamping block 14 is completed.

[0029] See Figures 9-12The sealing mechanism includes an annular sleeve 25 fixed transversely to the outer surface of the charging pile 1, and a rotating ring 26 is rotatably connected to the side opening of the annular sleeve 25. The middle part of the outer surface of both the rotating ring 26 and the annular sleeve 25 is provided with a movable hole that cooperates with the charging harness integration 2. The outer surface of the rotating ring 26 located on the inner side of the annular sleeve 25 is evenly provided with a plurality of groups of oblique grooves 34. The inside of the annular sleeve 25 is evenly provided with a plurality of guide frames 35 that cooperate with the oblique grooves 34. The inside of the guide frame 35 is slidably connected to a sliding block 36. A convex rod 37 is fixed to one side of the outer surface of the sliding block 36. The end of 37 passes through the oblique groove 34, and a connecting plate 38 is fixed on the other side of the outer surface of the sliding block 36. The end of the connecting plate 38 is movably passed through the outer side of the guide frame 35 and connected and fixed with the harness clamping plate 39. The clamping surface of the harness clamping plate 39 is provided with a sealing gasket layer 6 that cooperates with the charging harness integration 2. A damping spring 40 is provided inside the guide frame 35 and between the inner wall of the guide frame 35 and the outer surface of the sliding block 36. A side plate 27 is fixed on one side of the outer surface of the rotating ring 26, and a limiting groove 28 is provided on the side plate 27. A sleeve 29 is fixed on the outer surface of the charging pile 1, and a sliding connection is provided in the sleeve 29 There is a sliding member 30, and a spring 31 is provided between the sliding member 30 and the inner wall of the sleeve 29. The end of the sliding member 30 is fixed with a limit rod 32, and the top end of the limit rod 32 is movable through the outside of the sleeve 29 to be clamped in the limit groove 28, and the outer surface of the limit rod 32 is fixed with a side rod 33; through the design of the sealing mechanism, when the length adjustment of the charging harness integration 2 is completed, the charging harness integration 2 needs to be fixed again. At this time, the side rod 33 is stepped on by the toes again to drive the limit rod 32 to move into the sleeve 29 so that the end of the limit rod 32 will not affect the reset rotation action of the side plate 27, and then the side plate 27 is pushed to reset and rotate. , so that the limiting groove 28 at the end of the side plate 27 matches the end of the limiting rod 32. The rotation of the side plate 27 will drive the rotating ring 26 to rotate. The rotation of the rotating ring 26 will squeeze and push the protruding rod 37 through the several oblique grooves 34 opened on the outer surface of the side, thereby driving the sliding block 36 to slide linearly in the guide frame 35. While the sliding block 36 slides, it will push the wiring harness clamping plate 39 to move through the connecting plate 38, thereby making the sealing gasket layer 6 on the outer surface of the wiring harness clamping plate 39 integrated with the charging harness 2. When the limiting groove 28 matches the limiting rod 32, release the side rod 33. Under the action of the spring 31, the limiting rod 32 is clamped in the limiting groove 28, and the side plate 27 is clamped and fixed again.

[0030] When the charging pile 1 needs to be moved, the charging pile 1 can be tilted to release the universal wheels on the side of the charging pile 1 from the ground, thereby facilitating the pushing or dragging of the charging pile 1 by a trailer; when the charging pile 1 is moved, different models have different charging positions, and the required lengths of the charging harness integration 2 are also different.

When the charging harness is pulled out, the charging gun 3 is pulled out to extract the corresponding length of the charging harness integration 2. Without the restriction of the movable guide column 9, as the charging harness integration 2 is pulled out, the movable guide column 9 will gradually drop along the adjustment slot 8, so that the position of the charging gun 3 is adapted to the charging hole of the vehicle body; before the above-mentioned charging harness integration 2 is pulled out, it is necessary to first release the sealing fixation of the charging harness integration 2, that is, first step on the side rod 33 by the toe to drive the limit rod 32 to move into the sleeve 29 and then disengage the limit rod 32 from the side plate 27. Then, under the action of the damping spring 40, the sliding block 36 is reset The movement will drive the harness clamping plate 39 to move through the connecting plate 38, thereby releasing the squeezing of the charging harness integration 2 and facilitating the movement of the charging harness integration 2; when the length adjustment of the charging harness integration 2 is completed, the charging harness integration 2 needs to be fixed again. At this time, the side rod 33 is stepped on by the toes again to drive the limit rod 32 to move into the sleeve 29 so that the end of the limit rod 32 will not affect the reset rotation of the side plate 27, and then the side plate 27 is pushed to reset and rotate so that the limit groove 28 at the end of the side plate 27 matches the end of the limit rod 32, and the rotation of the side plate 27 The rotation will drive the rotating ring 26 to rotate. The rotation of the rotating ring 26 will squeeze and push the protruding rod 37 through a number of oblique grooves 34 provided on the outer surface of the side, thereby driving the sliding block 36 to slide linearly in the guide frame 35. While the sliding block 36 slides, it will push the wiring harness clamping plate 39 to move through the connecting plate 38, thereby making the sealing gasket layer 6 on the outer surface of the wiring harness clamping plate 39 integrated with the charging harness 2. When the limit groove 28 matches the limit rod 32, the side rod 33 is released. Under the action of the spring 31, the limit rod 32 is clamped in the limit groove 28, and the side plate 27 is clamped and fixed again.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
