Abstract
An operation unit for a construction machine includes an operation part configured to be operated to input a direction for operating the construction machine. When a first direction is input through the operation part, the operation part is configured to present a second direction corresponding to the first direction to an operator operating the operation part.
Claims12
An operation unit for a construction machine, comprising:
- an operation part configured to be operated to input a direction for operating the construction machine, the operation part including
- a movable part having both a steering member configured to be touched by the operator and a convex spherical member;
- a support part configured to support the convex spherical member of the movable part such that the convex spherical member is rotatable around two axes orthogonal to each other;
- and
- a driving part configured to rotate the convex spherical member of the movable part individually around each of the two axes,
- wherein, when a first direction is input through the operation part, the operation part is configured to present a second direction corresponding to the first direction to an operator operating the operation part by causing the driving part to rotate the convex spherical member,
- the steering member includes a pressing member configured to be pressed,
- the movable part has a cylindrical hollow portion for passing a signal line connected to the pressing member, and
- the support part has a shape that does not cover an opening that is one end of the hollow portion.

An operation unit for a construction machine, comprising:
- an operation part configured to be operated to input a direction for operating the construction machine;
- and
- a vibration mechanism configured to vibrate the operation part,
- wherein the operation part is configured to, when a first direction is input through the operation part,
- vibrate the vibration mechanism with a waveform asymmetric in an amplitude direction with respect to a reference value in order to generate a pseudo force for presenting a second direction corresponding to the first direction, and
- present the second direction to an operator operating the operation part.

An operation unit for a construction machine, comprising:
- an operation part configured to be operated to input a direction for operating the construction machine,
- wherein the operation part is configured to, when a first direction is input through the operation part, present a second direction corresponding to the first direction to an operator operating the operation part, and
- an operation signal corresponding to the first direction input through the operation part is transmitted to the construction machine via a wireless communication network.
