Abstract

A sensor unit includes a sensor module including a first plane and a second plane that crosses the first plane, and an armor body configured to house the sensor module. The armor body includes a first reference inner plane for positioning the first plane of the sensor module, a first reference outer plane parallel to the first reference inner plane and provided on an outer surface of the first reference inner plane, a second reference inner plane for positioning the second plane of the sensor module, and a second reference outer plane parallel to the second reference inner plane and provided on an outer surface of the second reference inner plane.

Claims

1. A sensor unit comprising:

a sensor module including a first plane and a second plane that crosses the first plane! and

an armor body configured to house the sensor module, wherein

the armor body includes;

a first reference inner plane for positioning the first plane of the sensor module;

a first reference outer plane parallel to the first reference inner plane and provided on an outer surface of the first reference inner plane;

a second reference inner plane for positioning the second plane of the sensor module; and

a second reference outer plane parallel to the second reference inner plane and provided on an outer surface of the second reference inner plane, wherein

the sensor module includes a first detection axis and a second detection axis that crosses the first detection axis,

the first reference inner plane is parallel to a plane defined by the first detection axis and the second detection axis, and

the second reference inner plane is parallel to the first detection axis.

3. The sensor unit according to claim 1, wherein the armor body includes a bottom wall and a plurality of sidewalls erected on the bottom wall, and

the sensor module is housed in an internal space surrounded by the bottom wall and the plurality of sidewalls.

4. The sensor unit according to claim 3, wherein, in the armor body, the first reference inner plane is provided on a bottom surface on the internal space side.

5. The sensor unit according to claim 3, wherein, in the armor body, the second reference inner plane is provided on a side surface on the internal space side.

6. The sensor unit according to claim 3, wherein the armor body includes a step on a bottom surface on the internal space side, and the second reference inner plane is provided on a side surface of the step.

7. The sensor unit according to claim 1, wherein a connector electrically connected to the sensor module is provided.

8. The sensor unit according to claim 3, wherein, in the armor body, a plane for positioning the sensor module is provided on at least one of both sides of the second reference inner plane.

10. An electronic device comprising the sensor unit according to claim 1.

11. A moving object comprising the sensor unit according to claim 1.

2. (canceled)

9. An armor body for a sensor module that houses the sensor module, the armor body comprising:

a first reference inner plane for positioning a first plane of the sensor module housed in the armor body;

a first reference outer plane parallel to the first reference inner plane and provided on an outer surface of the first reference inner plane;

a second reference inner plane for positioning a second plane of the sensor module housed in the armor body; and

a second reference outer plane parallel to the second reference inner plane and provided on an outer surface of the second reference inner plane.
