Description

  The present invention relates to a radio wave module mounting structure in which a radio wave module is attached to a license plate, and a license plate that can be attached to a vehicle body.

As a structure in which a radio module for an electronic license plate is attached to the license plate, the applicant has applied for Japanese Patent Application No. 2004-259687 and Japanese Patent Application No. 2005-129688. Among them, Japanese Patent Application No. 2004-259687 relates to a structure in which a radio wave module having a structure in which a battery cannot be replaced is attached to a license plate, and Japanese Patent Application No. 2005-129688 is a radio wave module having a structure in which a battery can be replaced. The present invention relates to a structure that can be attached to a plate.

  However, in the radio wave module mounting structure described in Japanese Patent Application Nos. 2004-259687 and 2005-129688, the radio module is mounted on the surface of the license plate, and the radio module is exposed on the surface of the license plate. There is a problem of losing aesthetics. There is also a problem that the existence of the radio wave module is easily known to a third party, so that it is intentionally mischievous or stolen.

  The present invention has been made in view of the circumstances described above, and its purpose is to avoid damaging the aesthetics, and to make it easy for a third party to know the existence of a radio module. An object of the present invention is to provide a radio wave module mounting structure and a license plate that can be avoided in advance and intentionally mischiefed or stolen.

  According to the first aspect of the present invention, a part or the whole of the plate body of the license plate that can be attached to the vehicle body is made of a radio wave transmitting material that transmits radio waves, and an antenna, a circuit board, and a circuit that constitute a radio module The element is built in a portion of the plate body made of a radio wave transmitting material. Thus, unlike the conventional one in which the radio module is mounted on the surface of the license plate, the radio module is exposed on the surface of the license plate by being embedded (embedded) in the license plate. It is possible to avoid damaging the aesthetics, and to prevent the existence of the radio module from being easily known to a third party and to be intentionally mischievous or stolen. Can be avoided.

  According to the invention described in claim 2, the battery capable of supplying operating power to the radio module is configured to be detachable from the radio module on the peripheral side surface of the license plate. As a result, the operating power is supplied to the radio module from a battery (main battery) separate from the radio module, so that the product life as the radio module can be extended, and the battery ( By limiting the usage conditions of the sub-cell), the capacity can be reduced and the size can be reduced. Furthermore, in this case, the battery (main battery) can be prevented from protruding from the surface of the license plate by attaching / detaching the battery (main battery) to / from the radio wave module on the peripheral side surface of the license plate. it can.

  According to the third aspect of the present invention, the battery is attached to or detached from the radio wave module in any of the upward direction, the lateral direction, and the downward direction of the license plate. Thereby, a battery (main battery) can be attached or detached from any one of the upward direction, the lateral direction, and the downward direction of the license plate.

  According to the invention described in claim 4, the battery capable of supplying operating power to the radio module is configured to be detachable from the radio module on the surface of the license plate. Thus, in the same manner as described in claim 2, the operating power is supplied to the radio module from a battery (main battery) separate from the radio module, thereby extending the product life as the radio module. In addition, by limiting the use conditions of a battery (sub battery) integrated with the radio wave module, the capacity can be reduced and the size can be reduced.

  According to the invention described in claim 5, the battery capable of supplying operating power to the radio module is configured to be detachable from the radio module on the back surface of the license plate. Thus, in the same manner as described in claims 2 and 4 above, operating power is supplied to the radio module from a battery (main battery) separate from the radio module, so that the product life as the radio module is reached. In addition, the capacity can be reduced and the size can be reduced by restricting the use conditions of the battery (sub battery) integrated with the radio wave module. Furthermore, in this case, the battery (main battery) can be prevented from protruding from the surface of the license plate by attaching / detaching the battery (main battery) to the radio wave module on the back surface of the license plate. .

  According to the invention described in claim 6, an antenna, a circuit board, and a circuit that can be attached to a vehicle body, and that a part or the whole of the plate body is made of a radio wave transmitting material that transmits radio waves, and constitutes a radio module. The element is built in a portion of the plate body made of a radio wave transmitting material. Thereby, the same effect as that described in claim 1 can be obtained. That is, since the radio wave module is incorporated (embedded) in the license plate, the radio wave module is not exposed on the surface of the license plate, and it is possible to avoid deteriorating the appearance. It can be avoided that the existence of the user is easily known to a third party and intentionally mischiefed or stolen.
