Abstract
A vehicle-mounted device includes a housing that accommodates electronic equipment therein, an openable and closable cover covering an opening of the housing, a sealing member fixed to the housing or the cover, and a pressure sensor fixed to at least one of the cover, the housing, or the sealing member at a position such that the pressure sensor is in contact with the sealing member while the cover is closed. The pressure sensor measures a pressing force received at the sealing member sandwiched between the housing and the cover. The vehicle-mounted device further includes a degradation determination device to determine whether any degradation occurs in the sealing member on the basis of the pressing force measured at the pressure sensor while the cover is closed.
Claims19
A vehicle-mounted device, comprising:
- a housing having an opening;
- a cover covering the opening, the cover being openable and closable;
- a sealing member fixed to the housing or the cover, the sealing member being sandwiched between the housing and the cover while surrounding the opening when the cover is closed;
- at least one pressure sensor fixed to at least one of the cover, the housing, or the sealing member at a position such that the at least one pressure sensor is in contact with the sealing member while the cover is closed, the at least one pressure sensor being configured to measure a pressing force received at the sealing member sandwiched between the housing and the cover while the cover is closed;
- a degradation determination device to determine whether any degradation occurs in the sealing member based on the pressing force measured at the at least one pressure sensor while the cover is closed;
- and
- a support member to support the cover, wherein
- at least one of the at least one pressure sensor is fixed to at least one of the cover, the housing, or the sealing member at a position between the cover or the housing and the sealing member while the cover is closed, the position being most distant from the support member while the cover is closed.
