Abstract

PROBLEM TO BE SOLVED: To provide an on-vehicle radio equipment that is easily mounted on a vehicle without giving damages thereto with safety. SOLUTION: In the on-vehicle radio equipment, a radio equipment main body 1 and an antenna 2 connecting thereto via a cable 3 are covered by an outer shell 4 freely deformed. The outer shell 4 is made of an elastic base stock such as a urethane rubber, a butyl rubber and a silicon rubber and has a hollow part 7 in its inside. In the case of using actually the on-vehicle radio equipment, the equipment is pushed into an acute angle part between a front glass 8 and a dash board 9. Then the outer shell 4 and the hollow part 7 are deformed in matching with the shape of the acute angle part, and the outer shell 4 comes closely in contact with the front glass 8 and the dash board 9. The deformed outer shell 4 produces a repulsive force, thereby producing a friction force between it and the front glass 8 and the dash board 9 to fix the entire equipment.

2. Description of the Related Art In recent years, a system for paying a toll on an expressway or the like without cash (hereinafter, referred to as an automatic toll collection system) has attracted attention. This system uses, for example, a credit card as a medium, and exchanges necessary information (user ID number, etc.) wirelessly to try to make the toll booth unmanned. There is a need for an in-vehicle wireless device that is mounted in a vehicle and exchanges data with an external device.

Conventionally, in order to fix the above-mentioned in-vehicle wireless device in a vehicle, a projection in a vehicle room such as a room mirror or a sun visor is used, or the wireless device is fixed on a dashboard with an adhesive or a screw. Or the method was adopted. However, according to the former method, the routing of the antenna cable and the like is likely to be complicated, and it is not easy to secure the driving view. On the other hand, in the latter method, once the attachment is performed, a scratch is left in the vehicle, and the attachment and detachment cannot be performed easily. Further, since the conventional in-vehicle wireless device is covered with a hard resin case or the like, there is a danger of being injured if it hits a passenger in an accident or the like.

[0004]

As described above, the conventional in-vehicle wireless device has problems in that it is difficult to secure a driver's field of view, it is difficult to mount and remove the device, and there is a danger in the event of an accident. Was. The present invention has been made in consideration of the above circumstances, and has as its object to provide an in-vehicle wireless device that can be easily mounted without damaging a vehicle and that does not impair safety.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a vehicle-mounted radio apparatus comprising an antenna unit and a radio unit connected to the antenna unit, wherein the radio device has an acute angle in a vehicle. It is characterized by comprising a holding means for holding at least the antenna portion by frictional force between the glass surface and the dashboard surface.

With this configuration, the antenna or the antenna and the radio body are fixed between the glass surface and the dashboard surface in the vehicle by frictional force. This makes it possible to mount the on-vehicle wireless device without hindering the driver's field of view and without damaging the inside of the vehicle.

Further, the present invention is characterized in that an elastic member such as rubber, which covers the antenna portion or the antenna portion and the radio device main body, is used as the holding means. In this way, for example, even if the vehicle collides with the occupant when an accident occurs, the impact force on the occupant is reduced by the elasticity of the elastic member. For this reason, safety for passengers can be improved.
