[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a mounting structure of an on-vehicle antenna, in particular, a GPS for receiving radio waves from artificial satellites.
POSITIONING SYSTEM) This relates to an antenna mounting structure.

[0002]

2. Description of the Related Art Conventionally, as means for attaching a GPS antenna to an automobile, an antenna case made of a synthetic resin having a built-in antenna body and an attachment portion to a trunk lid are integrally provided, and the trunk lid is attached to the trunk lid via the attachment portion. There is a method of attaching, and a method of attaching a housing to which a magnet is fixed to an antenna and adsorbing it to a vehicle body.

[0003]

However, in the above-described conventional means for attaching to a trunk lid, the attaching angle when attaching the antenna is fixed, and the attaching position is limited. Moreover, since the structure of the mounting member is not devised to lead out the antenna cable, there is a possibility that the antenna cable may be cut off at the edge of the antenna cable lead-out portion inside the mounting member. On the other hand, the conventional means for attaching the magnet-fixed casing to the antenna has a disadvantage that a separate casing for fixing the magnet is prepared, and this is attached to the antenna again, so that the entire antenna becomes large. Was.

Therefore, the present applicant has previously proposed a mounting structure in which the antenna case can be rotated by an arbitrary angle with respect to the mounting member to the trunk lid (Japanese Utility Model Application No. 3-94473). The present invention further improves this, and the antenna cable can be pulled out from any angle according to the selection of the angle of the antenna case, there is no risk of cutting the antenna cable, and the mounting member must be replaced. Accordingly, an object of the present invention is to provide a mounting structure of a vehicle-mounted antenna which can be easily changed to a mounting method by suction with a magnet, and which can be formed in a small and well-formed form.

[0005]

According to the present invention, there is provided a mounting structure for an on-vehicle antenna, wherein at least one convex portion protrudes outward from a circular peripheral portion at the center of a lower surface of an antenna case in which the antenna is mounted. At the center of the flat portion of the mounting member for mounting the antenna case, a plurality of convex portions are formed in the outer peripheral direction from the circular peripheral portion so as to engage with the projecting portion. In the mounting structure of the in-vehicle antenna, a fitting hole having a shape protruding is formed so that the antenna case can be mounted by rotating the antenna case at an arbitrary angle.
A cable fitting groove is formed on the lower surface of the antenna case so that an antenna cable led out of the antenna can be led out from an arbitrary angle direction, and the antenna cable pulled out from the cable fitting groove is fixed with a ring-shaped bush. It was done. In addition, a second mounting member is provided in place of the mounting member so that the second mounting member can be mounted in a magnet-attached manner, and the second mounting member has a fitting hole into which a protrusion provided on the antenna case fits. A magnet mounting portion for mounting a magnet holder holding a magnet is also formed, and the magnet holder and the second mounting member are jointly fastened to the antenna case via a mounting screw hole provided in the magnet holder. Configure.

[0006]

The antenna cable derived from the GPS antenna built in the antenna case is fitted into the cable fitting groove on the bottom side of the antenna case. When mounting on the trunk lid, rotate the antenna case with respect to the mounting member, select the angle position of the antenna, pull out the antenna cable from the cable fitting groove so as to correspond to this angle, and put the bush on the back of the antenna case The cable is fixed by fitting to the provided bush fitting portion.
When the antenna case is rotated at the time of setting the angular position of the antenna, the protrusion provided at the center of the lower surface of the antenna case fits into the fitting hole formed in the mounting member, but at this time, the protrusion is provided on the periphery of the protrusion. Is provided with at least one convex portion. On the other hand, since a plurality of convex portions are formed on the periphery of the fitting hole of the mounting member, the two convex portions are fitted at a predetermined angular position. The antenna case can be set at any angle. In this state, the antenna case and the mounting member are fixed with mounting screws from the back side of the mounting member. In the case of mounting by means of a magnet-based suction means, a second mounting member different from the mounting member is used. In this case, the direction of the antenna can be freely selected and the second mounting member can be used. It is unnecessary to set the angle of the antenna case with respect to the mounting member, and it is only necessary to fit the protrusion provided on the antenna case to the fitting portion formed on the second mounting member so as to correspond to the protrusion. A magnet holder is fitted to the magnet mounting portion of the second mounting member, and the magnet holder and the second mounting member are jointly fastened to the antenna case through mounting screw holes on the back side of the magnet holder with mounting screws. . In this case, the mounting operation is easy because the screw holes of the mounting member and the mounting screw holes of the magnet holder correspond to each other.

[0009]

According to the mounting structure of the in-vehicle antenna according to the present invention, when the GPS antenna is mounted on the trunk lid, it can be mounted at an arbitrary angle, and when the antenna is set at a predetermined angle. Since the cable can be pulled out so as to correspond to the position and is fixed by the bush, there is no possibility that the antenna cable is cut by the mounting member. By replacing the mounting member with the second mounting member, the mounting method can be easily changed to a mounting method by suction with a magnet. In this case, the magnet holder and the second mounting member are jointly fastened to the antenna case. Since the mounting operation is easy, the mounting screw hole of the magnet holder and the mounting member and the screw hole of the antenna case are made common, so that the number of mounting screw components can be reduced. . Further, since the magnet holder is directly fixed to the antenna case via the magnet mounting portion opened in the second mounting member, the height of the entire antenna can be reduced, the appearance is improved, and the components are improved. It has the advantage that it can be manufactured at low cost because it can be molded into a thin shape.
