Abstract
A navigation device includes an outer panel and an inertial sensor. The outer panel includes a pair of side plates separated from each other in a first direction and facing each other. A pair of fixing portions are provided on the pair of side plates. The pair of fixing portions are fixed to moving body-side fixing members. The inertial sensor is provided inside surrounded by the outer panel and arranged at a position sandwiched between the pair of fixing portions in the first direction.
Claims5
A navigation device comprising:
- an outer panel including a pair of side plates separated from each other in a first direction and facing each other;
- a plurality of fixing portions provided on the pair of side plates and to be fixed to moving body-side fixing members;
- and
- an inertial sensor provided inside surrounded by the outer panel and arranged at a position sandwiched between the plurality of fixing portions in the first direction,
- wherein a center of gravity position of the inertial sensor is located in a range between a front position and a last position of the plurality of fixing portions in a horizontal front-back axis direction, and between an uppermost position and a lowest position of the plurality of fixing portions in a vertical axis direction.

A method of manufacturing a navigation device comprising:
- in a pair of side plates of an outer panel in the navigation device that are separated from each other in a first direction, face each other, and include a plurality of fixing portions to be fixed to moving body-side fixing members, arranging a flat plate-shaped chassis in an orientation orthogonal to the pair of side plates at a position not corresponding to positions of the plurality of fixing portions between the pair of side plates when viewed from the first direction;
- attaching a sensor board on which an inertial sensor is mounted to a bracket having a predetermined shape;
- and
- fixing the bracket to a portion in the chassis where an amplitude is smaller than an amplitude at other portions in the chassis when vibration is applied to the navigation device, to arrange the inertial sensor at a position sandwiched between the plurality of fixing portions in the first direction,
- wherein the method of manufacturing a navigation device further comprises setting a center of gravity position of the inertial sensor in a range between a front position and a last position of the two or more fixing portions in a horizontal front-back axis direction, and between an uppermost position and a lowest position of the two or more fixing portions in a vertical axis direction.
