Description

Technical Field

[0001] The present invention relates to the technical field of casings for electrical equipment, and in particular to a lightning protection charging pile. Background Art

[0002] The function of a charging pile 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 parking lots or charging stations of public buildings and residential areas. Electric vehicles are charged through the charging pile. The input end of the charging pile is directly connected to the AC power grid. Each charging pile is equipped with a cable and a charging plug for charging electric vehicles. In order to adapt to the use of electric vehicles in different locations, the cables are mostly longer, and the cables are mostly coiled and hung outside the charging pile.

[0014] Compared with the prior art, the present invention provides a lightning protection charging pile with the following beneficial effects:

[0015] 1. This lightning-proof charging pile stores and protects the cable portion of the charging plug by providing a protective shell. When the charging plug is placed outside the charging pile body, the cable portion of the charging plug is coiled inside the protective shell to avoid being touched by newcomers and children nearby. At the same time, the charging plug can be conveniently stretched and stored in conjunction with the rotating component, fixed component, and control component. While improving the convenience of using the charging plug, it also effectively protects the charging plug, ensures the stable working state of the charging pile, and improves the safety of newcomers and children nearby.

[0016] 2. The lightning protection charging pile rotates the plug plate into the side groove and out of the inside of the short plate, grasps the short plate and drives the rotating handle to rotate around the circular axis. The rotating handle rotates and contacts the side of the baffle. When the rotating handle rotates, the baffle contacts the convex groove and is pushed by the rotation of the convex groove. The baffle moves away from the protective shell, and the baffle drives the connecting rod and moves the card plate out of the slot. At this time, the charging plug can be grasped and driven to stretch and move outward. At the same time, after resetting the rotating handle, the spring elastically resets and re-engages the inside of the slot to drive the charging plug with the round roller to fix it, thereby achieving the effect of quickly loosening or fixing the charging plug.

[0017] 3. The lightning protection charging pile stretches the charging plug outward. When the charging plug is pulled, the roller rotates. When the roller rotates, it drives the torsion spring to twist and contract. The torsion spring continues to contract as the charging plug is continuously pulled. When the user releases the charging plug, the roller is driven by the torsion spring to generate a reset force, which drives the roller to reset and rotate. The roller simultaneously and quickly drives the cable part of the charging plug to wrap around the outside of the roller, thereby shrinking the charging plug to its initial state, achieving the effect of quickly and automatically storing the cable part of the charging plug.

[0018] 4. The lightning protection charging pile rotates the rotating handle to the outside of the outer slot, and the plug plate drives the pressure plate to disengage from the inside of the horizontal slot. At this time, the linkage plate and the push plate are reset by the pulling force of the limit column, and the push plate moves inside the second fixed plate and away from the table. At this time, the table and the push plate are separated from the cable surface of the charging plug. At the same time, after the cable part of the charging plug is stretched, the rotating handle is rotated and reset to the inside of the outer slot. The short plate drives the pressure plate to push the linkage plate, and the linkage plate drives the push plate to squeeze the cable part of the charging plug, so that the fixing point of the cable part of the charging plug extends from the position of the wire hole to the position between the table and the push plate. The cable is pressed on the table by the push plate to fix the cable stably, avoiding the cable being shaken by external wind force and causing damage to the internal parts of the protective shell.

[0019] 5. The lightning protection charging pile is equipped with a lightning protection ring in conjunction with a lightning rod. In thundering weather, the lightning protection ring can share the lightning that directly strikes the charging pile body, and at the same time cooperate with the lightning rod and the down conductor to guide the current downward. The voltage-equalizing ring arranged outside the protective shell can protect the side lightning that strikes the protective shell and the side of the charging pile body. The voltage-equalizing ring shares the power of the side lightning and simultaneously cooperates with the down conductor to conduct it to the ground, effectively protecting the lightning that strikes the charging pile and improving the protection performance of the charging pile against lightning.

[0032] When using,

[0033] In the first step, by rotating the plug plate 45 into the side groove 47 and disengaging from the inside of the short plate 48, grasp the short plate 48 and drive the rotating handle 42 to rotate around the circular axis 44, the rotating handle 42 rotates and contacts the side of the baffle 31, and when the rotating handle 42 rotates, the baffle 31 contacts the convex groove 43 and is pushed by the rotation of the convex groove 43 to the baffle 31, and the baffle 31 moves away from the protective shell 14. The baffle 31 drives the connecting rod 37 and moves the card plate 36 out of the card slot 21. At this time, the charging plug 13 can be grasped and driven to stretch and move outward. At the same time, after resetting the rotating handle 42, the spring 33 elastically resets and re-engages in the inside of the card slot 21, driving the round roller 22 to drive the charging plug 13 to fix it, thereby achieving the effect of quickly loosening or fixing the charging plug 13.

[0034] In the second step, by stretching the charging plug 13 outward, the charging plug 13 drives the round roller 22 to rotate when being pulled. The round roller 22 drives the torsion spring 24 to twist and contract when rotating. The torsion spring 24 continues to contract when the charging plug 13 is continuously pulled. When the user releases the charging plug 13, the round roller 22 is driven by the restoring elastic force generated by the torsion spring 24 to restore and rotate the round roller 22. The round roller 22 simultaneously and quickly drives the cable portion of the charging plug 13 to wrap around the outside of the round roller 22, thereby shrinking the charging plug 13 to its initial state, thereby achieving the effect of quickly and automatically storing the cable portion of the charging plug 13.

[0035] The third step is to rotate the rotating handle 42 outward from the outer notch 41, and the insert plate 45 drives the pressure plate 46 to disengage from the inside of the transverse groove 58. At this time, the connecting plate 57 and the push plate 53 are reset by the pulling force of the limit column 56, and the push plate 53 moves inside the second fixed plate 54 and away from the table plate 52. At this time, the table plate 52 and the push plate 53 are separated from the cable surface of the charging plug 13. At the same time, after the cable part of the charging plug 13 is stretched, the rotating handle 42 is rotated and reset to the inside of the outer notch 41 again. The short plate 48 drives the pressure plate 46 to push the connecting plate 57. At the same time, the connecting plate 57 drives the push plate 53 to squeeze the cable part of the charging plug 13, so that the fixing point of the cable part of the charging plug 13 extends from the position of the wire hole 18 to the position between the table plate 52 and the push plate 53. The cable is pressed on the table plate 52 by the push plate 53 to fix the cable stably, thereby preventing the cable from being shaken by external wind force and causing damage to the internal parts of the protective shell 14.
