Abstract

The disclosure provides a charger including a base and a charging circuit. The base includes a coupling portion for detachably coupling with one of multiple supporting stands. Each of the supporting stands has a supporting container with different standards. The coupling portion has a coupling surface. The coupling surface is used for supporting one of the supporting stands. The charging circuit is disposed in the base and the charging circuit has a first electrical connector. The first electrical connector protrudes from the coupling surface. When the coupling portion is coupled with the supporting stand, a portion of the first electrical connector is disposed in the supporting container.

Claims

1. A charger, comprising:

a base comprising a coupling portion and a coupling indentation and having an upper surface, the coupling portion being for detachably coupling with one of a plurality of supporting stands, the coupling indentation being for detachably coupling with one of a plurality of battery boxes, each of the supporting stands having a supporting container with different standards, the coupling portion having a coupling surface, the coupling surface being used for supporting one of the supporting stands; and

a charging circuit disposed in the base and the charging circuit having a first electrical connector and a second electrical connector, wherein the first electrical connector protrudes from the coupling surface, when the coupling portion is coupled with one of the supporting stands, a portion of the first electrical connector is disposed in the supporting container, the second electrical connector is disposed in the coupling indentation, the battery boxes are used for being detachably installed in the coupling indentation, each of the battery boxes has an accommodating indentation and a third electrical connector, a portion of the third electrical connector is disposed in the accommodating indentation, the third electrical connector is used for being detachably and electrically connected to the second electrical connector, and the accommodating indentation is used for accommodating at least one battery;

wherein each of the battery boxes comprises a first fitting portion and a second fitting portion, the first fitting portion and the second fitting portion are disposed on two sides of the each of the battery boxes opposite to each other, the base comprises a third fitting portion and a fourth fitting portion, the third fitting portion and the fourth fitting portion are disposed on two sides of the coupling indentation opposite to each other, the first fitting portion is fastened with the third fitting portion, and the second fitting portion is fastened with the fourth fitting portion;

wherein the upper surface is connected with sidewalls of the coupling indentation, the second fitting portion comprises an elastic piece and a convex-shaped block, the elastic piece has a fastening section and a releasing section connected with each other, the fastening section is connected with one of the battery boxes, the fastening section is positioned between the one of the battery boxes and the base, the convex-shaped block is disposed on a surface of the fastening section facing the coupling indentation, a portion of the releasing section protrudes from the upper surface, the fourth fitting portion is a concave indentation, the convex-shaped block faces the fourth fitting portion, and the convex-shaped block is fastened with the fourth fitting portion by the elastic piece, the releasing section is adapted to being pressed to move the convex-shaped block away from the fourth fitting portion.

2. The charger as claimed in claim 1, wherein the coupling portion comprises two fastening pieces disposed on two sides of the coupling surface opposite to each other, each of the supporting stands comprises two fastening indentations disposed on two sides of the each of the supporting stands opposite to each other, the two fastening pieces are used for being fastened with the two fastening indentations correspondingly such that the each of the supporting stands is detachably fastened on the base, and the portion of the first electrical connector is disposed in the supporting container.

3. The charger as claimed in claim 1, wherein the first fitting portion is convex-shaped block, and the third fitting portion is a concave indentation.
