Abstract

A wireless charging system for charging a tool includes a tool holder and charging module. The tool holder includes a mounting interface, a holding portion extending from the mounting interface, and at least one surface t configured to mount the tool holder onto a support surface, such as of a mobile structure. The charging module is mounted in the mounting interface, and includes an inductive charging device that wirelessly charges a tool resting on the charging module. The holding portion is configured to at least partially engage the tool and act as a transverse support relative to the mounting interface. The at least one surface can include a base of the tool holder for horizontal mounting, a side of the tool holder for vertical mounting, or two opposite sides of the tool holder for mounting on a mounting rail.

Claims

1. A wireless charging system, comprising:

a tool holder that includes;

a mounting interface; and

a holding portion that extends from an end region of the mounting interface; and

at least one mounting hole that passes from a first side of the tool holder through to a second side of the tool holder opposite the first side;

at least one rail attachment member received in the at least one mounting hole such that a portion of the at least one rail attachment member protrudes from at least one of the first side and the second side of the tool holder;

the portion of the at least one rail attachment member protruding out from the tool holder configured to be mounted in at least one mounting rail to mount the tool holder on the at least one mounting rail; and

a charging module that defines a charging surface, that is configured to be mounted in the mounting interface of the tool holder, and that includes an inductive charging device configured to wireless charge a device resting on the charging surface;

the holding portion of the tool holder having a shape configured to at last partially engage a geometry of the device such that the holding portion acts as a transverse support for the device relative to the mounting interface.

2. The system of claim 1, wherein the support surface is a surface of a mobile structure.

3. The system of claim 1, further comprising at least one damping element configured to be positioned between the tool holder and the support surface as the tool holder is mounted to the support surface.

4. The system of claim 1, wherein the tool holder is configured to mount the charging module such that the charging surface is at an angle relative to a horizontal plane.

5. The system of claim 1, wherein the tool holder includes an inner wall and an outer wall separated by a gap configured to damp vibrations in the tool holder.

6. The system of claim 1, further comprising at least one attachment member, wherein:

the mounting element includes at least one mounting hole;

the support surface defines at least one receiving hole corresponding to the at least one mounting hole; and

the at least one attachment member is configured to be received in both the at least one mounting hole and the at least one receiving hole to mount the tool holder on the support surface.

7. The system of claim 1, wherein one of the at least one surface of the tool holder defines a base of the tool holder, and is configured to mount the tool holder on a support surface that is substantially horizontal.

8. The system of claim 1, wherein a first of the at least one surface of the tool holder defines a first side of the tool holder, and is configured to mount the tool holder on a support surface that is substantially vertical.

9. The system of claim 8, wherein a second of the at least one surface of the tool holder defines a base of the tool holder, and is configured to mount the tool holder on a support surface that is substantially horizontal.

10. A wireless charging system, comprising:

a tool holder that includes;

a first mounting interface; and

a holding portion that extends from an end region of the mounting interface; and

at least one surface that defines a mounting element configured to mount the tool holder onto a support surface;

a docking frame configured to be removably mounted in the first mounting interface, the docking frame including a second mounting interface;

a charging module that defines a charging surface, that is configured to be removably mounted in the second mounting interface, and that includes an inductive charging device; and

a power tool that includes a wirelessly rechargeable battery, and that is configured to be removably disposed on the charging surface of the charging module such that the holding portion at least partially transversely supports the power tool relative to the first mounting interface.

11. The system of claim 10, further comprising:

a further power tool having at least one of a geometry and a wirelessly rechargeable battery that is different from a geometry and the wirelessly rechargeable battery of the power tool.

12. The system of claim 11, further comprising at least one of:

a further charging module that corresponds to the different wirelessly rechargeable battery; and

a further docking frame that corresponds to the different geometry;

the charging module and the docking frame being selectably replicable by the further charging module and the further docking frame, respectively.

13. The system of claim 11, further comprising at least one attachment member, wherein:

the mounting element includes at least one mounting hole;

the support surface defines at least one receiving hole corresponding to the at least one mounting hole; and

the at least one attachment member is configured to be received in both the at least one mounting hole and the at least one receiving hole to mount the tool holder on the support surface.

14. The system of claim 11, wherein one of the at least one surface of the tool holder defines a base of the tool holder, and is configured to mount the tool holder on a support surface that is substantially horizontal.

15. The system of claim 11, wherein a first of the at least one surface of the tool holder defines a first side of the tool holder, and is configured to mount the tool holder on a support surface that is substantially vertical.

16. The system of claim 15, wherein a second of the at least one surface of the tool holder defines a base of the tool holder, and is configured to mount the tool holder on a support surface that is substantially horizontal.

17. The system of claim 15, further comprising at least one rail attachment member, wherein:

a second surface of the at least one surface of the tool holder defines a second side of the tool holder opposite the first side;

the mounting element includes at least one mounting hole that passes from the first side through to the second side;

the at least one rail attachment member is received in the at least one mounting hole such that a portion of the at least one rail attachment member protrudes from at least one of the first side and the second side of the tool holder; and

the portion of the at least one rail attachment member protruding out from the tool holder is configured to be mounted in at least one mounting rail included on the support surface to mount the tool holder on the support surface.

18. The system of claim 11, wherein the support surface is a surface of a mobile structure.

19. A wireless charging system, comprising:

a charging module that includes;

a charging surface; and
