Abstract

A charging pile includes a case and a charging gun base. The charging gun base is received in the case. The charging gun base is exposed from a side of the case. The charging gun base further includes a cover and a snap unit. The cover is coupled onto the case through the snap unit. The cover is rotatable relative to the case, thereby covering or exposing the charging gun base. When covering, the cover renders the charging gun base waterproof.

Claims

1. A charging pile, comprising:

a case;

a charging gun base received in the case, and the charging gun base exposed from the case;

a snap unit mounted on the case, comprising;

a shaft unit coupled onto the case; and

a torsion spring, one end of the torsion spring sheathed onto the shaft unit, and the other end of the torsion spring pressed against the cover;

a cover coupled onto the case through the snap unit; and

wherein the cover is rotatable relative to the case, thereby covering or exposing the charging gun base; and

wherein the torsion spring applies a torque on the cover to expose the charging gun base;

the torsion spring comprises a retaining ring and two socket ring units, the cover comprises a buckle formed thereon, and the buckle is pressed against the retaining ring;

the cover is rotatably sheathed onto the shaft unit, and the shaft unit is inserted in the two socket ring units.

2. The charging pile of claim 1,

wherein the snap unit further comprises a button mounted on the case, and the case comprises a hook;

wherein when the cover is rotated to cover the charging gun base and the button is pressed under an external force, the button is engaged with the hook, thereby overcoming the torque of the torsion spring to keep the cover covering the charging gun base; and

wherein when the button is pressed again, the button releases the hook, thereby the cover is returned to expose the charging gun base.

3. The charging pile of claim 2, wherein the cover comprises:

a covering part configured to cover the charging gun base;

an elastic part extending outwards from an end of the covering part; and

a bending part, one end of the bending part coupled onto the elastic part, and the other end of the bending part sheathed onto the shaft unit; and

wherein the bending part is rotatable relative to the shaft unit.

4. The charging pile of claim 3,

wherein a chamber is defined on the case, the chamber being recessed inwards from an outside surface of the case;

wherein the hook is positioned in the chamber, the hook extends upwards from a bottom surface of the chamber;

wherein the shaft unit is on the chamber; and

wherein when the cover is covering the charging gun base, the bending part is received in the chamber.

5. The charging pile of claim 4,

wherein an opening is defined on the case, the opening is configured to expose the charging gun base;

and

wherein the opening is located beside the chamber, and a baffle is provided to separate the opening and the chamber.

6. The charging pile of claim 3,

wherein the bending part comprises two branches, the two branches are abreast and apart from each other;

wherein one end of each branch is coupled onto the elastic part, and the other end of each branch is rotatably sheathed onto the shaft unit; and

wherein the torsion spring is between the two branches.

7. The charging pile of claim 6, wherein the bending part further comprises an enhancing board, the enhancing board is between the two branches to connect the two branches.

8. The charging pile of claim 3,

wherein the cover further comprises an elastic member, the elastic member is on the covering part;

and

wherein the elastic member faces the charging gun base and is configured to seal the charging gun base.

9. The charging pile of claim 8, wherein the elastic member is formed on the covering part by injection molding.

10. The charging pile of claim 3,

wherein the cover further comprises a receiving part, the receiving part is coupled onto the elastic part, and the receiving part faces the case;

and

wherein the receiving part is hollow, and the button is mounted and received in the receiving part.

11. The charging pile of claim 1,

wherein the shaft unit comprises a first shaft and a second shaft, the first shaft and the second shaft are mounted on the case, the first shaft and the second shaft are parallel and separated from each other;

and

wherein each socket ring unit comprises a first socket ring and a second socket ring; and

wherein the cover is rotatably sheathed onto the first shaft, the first shaft is inserted in the first socket rings, and the second shaft is inserted in the second socket rings.

12. The charging pile of claim 1, further comprising a holder, and

wherein the holder is mounted and received in the case, and the charging gun base is mounted on the holder.

13. The charging pile of claim 1,

wherein the case comprises a front shell and a rear shell, the front shell and the rear shell are relatively coupled;

and;

wherein a cavity is defined between the front shell and the rear shell, and the charging gun base is in the cavity.

14. The charging pile of claim 13,

wherein the charging gun base is mounted on the rear shell, and the charging gun is exposed from the front shell;

and

wherein the cover is coupled onto the front shell, and the cover is rotatable relative to the front shell.
