Abstract

A power supply system may comprise an electrical machine, and a battery pack configured to be detachably attached to the electrical machine by being slid in a sliding direction with respect to the electrical machine. The electrical machine may include a machine-side power terminal, and protective ribs disposed on both sides of the machine-side power terminal respectively and extending beyond the machine-side power terminal. The battery pack may include a battery-side power terminal configured to mechanically engage with and electrically connect to the machine-side power terminal, and a case accommodating the battery-side power terminal. The case may include a power terminal opening disposed at a position facing the battery-side power terminal in the sliding direction, and recessed grooves disposed on both sides of the battery-side power terminal respectively and extending along the sliding direction.

First claim

What is claimed is:

1 . A power supply system comprising:
an electrical machine; and a battery pack configured to be detachably attached to the electrical machine by being slid in a sliding direction with respect to the electrical machine, wherein the electrical machine includes:
a machine-side power terminal; and
protective ribs disposed on both sides of the machine-side power terminal respectively and extending beyond the machine-side power terminal,
the battery pack includes:
a battery-side power terminal configured to mechanically engage with and electrically connect to the machine-side power terminal; and
a case accommodating the battery-side power terminal, and
the case includes:
a power terminal opening disposed at a position facing the battery-side power terminal in the sliding direction; and
recessed grooves disposed on both sides of the battery-side power terminal respectively and extending along the sliding direction.

2 . The power supply system according to claim 1 , wherein
the electrical machine further includes a machine-side signal terminal, the protective ribs are also disposed on both sides of the machine-side signal terminal respectively and extending beyond the machine-side signal terminal, the battery pack further includes a battery-side signal terminal accommodated in the case and configured to mechanically engage with and electrically connect to the machine-side signal terminal, the case further includes a signal terminal opening disposed at a position facing the battery-side signal terminal in the sliding direction, and the recessed grooves are also disposed on both sides of the battery-side signal terminal respectively.

3 . The power supply system according to claim 1 , wherein
the electrical machine further includes a machine-side slide rail, at least one of the protective ribs is disposed between the machine-side slide rail and the machine-side power terminal, the battery pack further includes a battery-side slide rail configured to slidably engage with the machine-side slide rail in the sliding direction, and at least one of the recessed grooves is disposed between the battery-side slide rail and the battery-side power terminal.

4 . An electrical machine configured to have a battery pack detachably attached thereto by the battery pack being slid in a sliding direction, the electrical machine comprising:
a machine-side power terminal; and protective ribs disposed on both sides of the machine-side power terminal respectively and extending beyond the machine-side power terminal.

5 . The electrical machine according to claim 4 , further comprising a machine-side signal terminal,
wherein the protective ribs are also disposed on both sides of the machine-side signal terminal respectively and extending beyond the machine-side signal terminal.

6 . The electrical machine according to claim 4 , further comprising a machine-side slide rail,
wherein at least one of the protective ribs is disposed between the machine-side slide rail and the machine-side power terminal.

7 . A battery pack configured to be detachably attached to an electrical machine by being slid with respect to the electrical machine in a sliding direction, the battery pack comprising:
a battery-side power terminal; and a case accommodating the battery-side power terminal, wherein the case includes:
a power terminal opening disposed at a position facing the battery-side power terminal in the sliding direction; and
recessed grooves disposed on both sides of the battery-side power terminal respectively and extending along the sliding direction.

8 . The battery pack according to claim 7 , further comprising a battery-side signal terminal accommodated in the case,
wherein the case further includes a signal terminal opening disposed at a position facing the battery-side signal terminal in the sliding direction, and the recessed grooves are also disposed on both sides of the battery-side signal terminal respectively.

9 . The battery pack according to claim 7 , further comprising a battery-side slide rail,
wherein at least one of the recessed grooves is disposed between the battery-side slide rail and the battery-side power terminal.
