Abstract

A drilling device, including a motor, a battery, and a frame. The battery is electrically connected to the motor. The frame includes a base, a column supported by the base, and a drill support part configured to be movable relative to the base. The battery is disposed on the base such that the drill support part is configured to be movable relative to the battery.

Claims (36)

1 . A drilling device, comprising:

a motor;

a battery, electrically connected to the motor;

a frame, comprising:

a base;

a column, supported by the base;

a drill support part, configured to be movable relative to the base;

wherein the battery is disposed on the base, such that the drill support part is configured to be movable relative to the battery,

wherein the drilling device further comprises a drill holder fixed to the drill support part, and when viewed in a direction orthogonal to an axial direction taken from a bottom end of the column to a top end of the column, the drill holder is disposed on a front side of the column along a front-rear direction taken from the battery to the column and the battery is disposed on a rear side of the column opposite to the front side along the front-rear direction.

2 . The drilling device according to claim 1 , further comprising:

a wire, electrically connecting the battery to the motor;

an actuator, coupled to the drill support part and configured to move the drill support part towards the base and away from the base;

a wheel attached to the frame; and

a hand bar attached to the frame;

wherein the drill support part is coupled to the column such that the drill support part is slidable on the column.

3 . The drilling device according to claim 2 , wherein the motor is a brushless DC motor, and the drill support part is coupled to the column.

4 . The drilling device according to claim 3 , further comprising a drill attached to the drill holder, wherein the motor is disposed on the drill support part such that the motor is movable relative to the battery.

5 . The drilling device according to claim 4 , wherein when viewed in the axial direction of the column, the battery is disposed such that the battery and the drill do not overlap with each other.

6 . The drilling device according to claim 5 , wherein the battery is detachably attached to the base.

7 . The drilling device according to claim 4 , wherein when viewed in the axial direction of the column, the battery is disposed such that the battery and the drill support part do not overlap with each other.

8 . The drilling device according to claim 7 , wherein the battery is detachably attached to the base.

9 . The drilling device according to claim 4 , wherein when viewed in the axial direction of the column, the battery is disposed such that the battery and the motor do not overlap with each other.

10 . The drilling device according to claim 9 , wherein the battery is detachably attached to the base.

11 . The drilling device according to claim 2 , further comprising a second column supported by the base, wherein the drill support part is coupled to the second column such that the drill support part is slidable on the second column.

12 . The drilling device according to claim 1 , wherein the battery is a rechargeable battery.

13 . The drilling device according to claim 1 , further comprising a second battery disposed on the base such that the drill support part is movable relative to the second battery, wherein the second battery is electrically connected to the motor.

14 . A drilling device, comprising:

a motor;

a battery, electrically connected to the motor;

a frame, comprising:

a base;

a column, supported by the base;

a drill support part, configured to be movable relative to the base;

wherein the battery is disposed on the base, such that the drill support part is configured to be movable relative to the battery,

wherein the drilling device further comprises a drill holder fixed to the drill support part, a front wheel attached to the frame and a rear wheel attached to the frame, and the front wheel is located between the drill holder and the rear wheel along a front-rear direction taken from the battery to the column,

wherein a rotation axis of the front wheel and a rotation axis of the rear wheel are perpendicular to the front-rear direction.
