Definitions
- the present invention relates to a marker that is a ground-fixed type wireless communication unit used for wireless communication with a moving body such as an automobile or a railcar, and in particular, for suppressing a temperature change of an electronic circuit board mounted on the marker. It depends on the mounting structure of the board.
- Patent Document 1 an impact absorbing material having a relative dielectric constant equal to or lower than that of the radome material is laminated on the upper surface of the radome material in the upper part of the antenna housed in the marker to constitute a marker. It is described to provide a marker with excellent properties.
- the case surface temperature is lower than the outside air temperature due to heat radiation from the upper surface of the housing 7 to the sky. That is, the fluctuation of the housing surface temperature is larger than the fluctuation of the outside air temperature of the day.
- the electronic circuit board 9 is also exposed to severe temperature fluctuation.
- FIG. 1 is a perspective view of an installation form of an automobile marker.
- FIG. 2 is a cross-sectional view of the conventional marker taken along the line AA ′ in FIG.
- FIG. 3 is an exploded view of a marker according to an embodiment of the present invention.
- FIG. 4 is a perspective view from the top surface side of the marker according to one embodiment of the first embodiment of the present invention.
- FIG. 5 is a perspective view from the lower surface side of the marker according to one embodiment of the first embodiment of the present invention.
- 6 is a cross-sectional view taken along the line BB ′ in FIG. 4 of the marker according to an embodiment of the present invention.
- 7 is a cross-sectional view of the marker according to one embodiment of the present invention, taken along the line BB ′ in FIG.
- FIG. 1 is a perspective view of an installation form of an automobile marker.
- FIG. 2 is a cross-sectional view of the conventional marker taken along the line AA ′ in FIG.
- FIG. 3 is an
- FIG. 5 is a perspective view of the marker as seen from the lower surface side.
- the lower housing part 13 is provided with an uneven part 16, and this uneven part increases the surface area of the lower surface of the housing and improves the heat dissipation effect from the lower part of the marker. I am trying.
- the lower housing part 13 is arranged so as to enter the inside of the side surface part of the upper housing part 12. With such a configuration, it is possible to make it difficult for rainwater to enter the inside of the marker.
- the mounting base 10 is configured to cover the entire surface of the lower housing part 13, the heat dissipation performance from the lower surface of the lower housing part 13 may be reduced. It is comprised so that a part of body part 13 may be covered.
- the joint surface end 18 of the upper housing portion 12 and the lower housing portion 13 has a structure such that the marker lower surface side is not directly exposed to raindrops. Is desirable. That is, it is desirable to arrange the lower housing part 13 so as to enter the inside of the side surface part of the upper housing part 12.
