Description

  The present invention relates to an antenna device, and more particularly to an antenna device attached to an automobile.

  In the conventional automobile design field, in order to receive a broadcast program by a radio system, it is common to mount an antenna on the body of an automobile. At present, as a common antenna, there are many designs including an antenna seat fixed to the outer surface of a vehicle body and a long rod-shaped antenna body fixed to the antenna seat with a screw. Since such a long rod-shaped antenna body is very common, in order to make the antenna body unique, some car owners install other decorations on the antenna body separately, for example, dolls etc. . However, this cannot fulfill the wishes of all car owners.

  In another type of antenna design, the antenna body is significantly shortened to a short rod shape, and a plastic shark dorsal fin case is installed on the outer surface to cover the antenna seat and the short rod-shaped antenna body. To do. A shark dorsal fin case provides a kind of different antenna configuration. Furthermore, some traders directly use shark dorsal fin case seats instead of short rod antenna bodies. In other words, we expect to use the shark's dorsal fin case directly as the antenna body. On the other hand, the reason why the shark's dorsal fin case is made of carbon fiber is to receive broadcast program signals using the electrical conductivity of carbon fiber, and another reason is that carbon fiber itself. This is to obtain a special antenna texture by using the unique pattern. However, there is room for improvement because the receiving effect of such an antenna body made of direct carbon fiber is poor and there are many noise signals.

  Therefore, an object of the present invention is to provide an antenna device made of a carbon fiber material that can obtain a relatively good signal receiving effect.

  Therefore, the antenna device of the present invention is an antenna device suitable for mounting on an automobile, and is electrically connected to the antenna seat of the automobile, and includes an antenna body and a signal line unit. A mounting space that opens downward is defined inside the antenna body, and further includes a carbon fiber case layer that opens downward, an electrical insulating layer that is covered and fixed on the inner surface of the carbon fiber case layer, and electrical insulation. An electrically conductive metal layer coated and fixed to the layer and facing the carbon fiber layer with a gap therebetween. The signal line unit is fixedly attached to be electrically connected to the antenna seat at the same time as being electrically connected to the electrically conductive metal layer.

  As an effect of the present invention, according to the layered structure design in the antenna body, not only the antenna body can obtain a relatively good receiving effect, but also the antenna using the carbon fiber pattern of the carbon fiber case layer in the antenna body. The entire device can have a texture different from that of a known antenna, and a kind of new antenna device configuration that can be selected by the consumer can be provided.

Other features and advantages of the present invention will become apparent from the embodiments with reference to the drawings.

  As shown in FIGS. 1, 2, and 3, a preferred embodiment of the antenna device of the present invention can be mounted on an automobile 900, and an antenna seat 901 attached to the automobile 900 so that broadcast programs can be received. And is electrically connected. When this antenna device is electrically connected to the pedestal 3, the insulating pad 4 attached to the pedestal 3, the antenna body 5 fixedly mounted on the insulating pad 4 so as to cover the pedestal 3, and the antenna body 5. At the same time, a signal line unit 6 electrically connected to the antenna seat 901 is provided.

  The pedestal 3 is attached and fixed to the outer surface of the automobile 900 and covers the antenna seat 901 from the outside. In addition, the antenna seat 901 has a through hole 30 provided so that a part of the antenna seat 901 can penetrate upward. The insulating pad 4 is installed so as to surround the periphery of the bottom side of the pedestal 3, and is affixed in contact with the outer surface of the automobile 900. Since the pedestal 3 and the insulating pad 4 are well-known members, there are many types, and detailed description thereof will be omitted.

  The antenna body 5 has a shark's dorsal fin shape, and a mounting space 50 opened downward is defined in the antenna body 5. The antenna body 5 is connected between the two side walls 51 that are connected to each other at the upper edges, are inclined in the opposite direction and are inclined downward, and the rear end of the side wall 51 so as to extend vertically. Further, the rear end wall portion 52 integrally connected to the side wall portion 51 and the upper edge of the side wall portion 51 so as to extend up and down are fixed and located in the mounting space 50. Columnar mounting connecting portion 53, and the upper edge of the side wall portion 51 gradually bends in an arc shape from the front to the back and extends upward, while the rear end wall portion 52 extends from the top. It extends in an arc shape down and forward.

  This will be described with reference to FIG. The antenna body 5 is a layered structure, and a shark's dorsal hollow carbon fiber case layer 54 that is stacked and fixed on the insulating pad 4 so as to cover the pedestal 3 downward, and a carbon fiber An electrically insulating layer 55 coated on the inner surface of the case layer 54, and an electrically conductive metal layer 56 facing the carbon fiber case layer 54 with a gap by being coated and fixed on the inner surface of the electrically insulating layer 55 With. The carbon fiber case layer 54 is integrally formed of carbon fibers, and a carbon fiber pattern appears on the outer surface.

  The signal line unit 6 is fixedly attached to the bottom end of the attachment connecting portion 53 and electrically connected to the electrically conductive metal layer 56, and the signal electrically connected to the antenna seat 901 and fixedly attached thereto. A line 62 and an inductance element 63 electrically connected between the electrically conductive component 61 and the signal line 62 are provided. The electrically conductive component 61 includes a horizontal sheet-like fixing portion 611 that is locked and fixed to the bottom end of the attachment connecting portion 53 by a bolt 60, and extends from the fixing portion 611 to the left and right, respectively, and extends downward. It has two sheet-like electrical connection portions 612 that are attached to the conductive metal layer 56 and electrically connected. The signal line 62 has an attachment annular portion 621 attached to and electrically connected to the end face of the antenna seat 901 and locked to the antenna seat 901 by a bolt 800.

  When the antenna device of the present invention is installed and used, the signal wire 62 extends downward and is exposed to the outside of the through hole 30 of the base 3, so that the signal wire 62 is fixed to the antenna seat 901 with a screw. The pedestal 3 may be installed so as to cover the outside of the antenna seat 901 with the through hole 30 of the pedestal 3 facing downward. The attachment is completed by attaching and fixing the base 3 to the outer surface of the automobile 900. At that time, the radio wave signal is received by the electrically conductive metal layer 56 in the antenna body 5 and the radio wave signal is transferred. After passing through the electrically conductive component 61, the low frequency noise signal is filtered by the inductance element 63 and then transmitted to the antenna seat 901 through the signal line 62. This makes it possible to listen to the broadcast program from the radio system in the automobile 900.

  The layered structure design composed of the carbon fiber case layer 54, the electrical insulating layer 55, and the electrically conductive metal layer 56 of the antenna body 5 greatly improves the reception quality of radio wave signals, and the inductance element 63 By installing, the interference of the low frequency noise signal can be reduced, and the clarity of the received broadcast program signal can be greatly improved.

  As shown in FIGS. 3 and 5, in this embodiment, the electrically conductive component 61 is locked to the mounting connecting portion 53 by the bolt 60, but it is not necessary to install the mounting connecting portion 53 in actual implementation. Absent. The electrically conductive component 61 may be directly electrically connected to the electrically conductive metal layer 56 and fixed. In addition, it is not essential to install the electrically conductive component 61. One end of the inductance element 63 may be directly electrically connected to the electrically conductive metal layer 56. In this case, similarly, a radio wave signal can be transmitted using the electrical coupling effect between the carbon fiber case layer 54 and the electrically conductive metal layer 56. As a function of the inductance element 63, the low frequency noise signal in the signal is filtered. In actual implementation, the inductance element 63 is not essential, and the signal line 62 may be directly electrically connected between the electrically conductive metal layer 56 and the antenna seat 901.

  As described above, according to the layered structure design of the antenna body 5, the antenna body 5 made of carbon fiber not only provides relatively good wireless electrical signal reception quality, but also the carbon fiber case layer in the antenna body 5. The entire antenna device can be made to have a texture different from that of a known antenna by using 54 carbon fiber patterns. Thus, a kind of new antenna device configuration that can be selected by the consumer is provided, and thus the object of the present invention can be achieved.
