Antenna of vehicle
[12] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna for a vehicle, and more particularly, to an antenna of a vehicle that is capable of improving a reception state of radio waves by minimizing a flow caused by air pressure during high speed driving.
[13] In general, an antenna for receiving a radio wave of a radio is installed on an outer panel of a vehicle, and a car usually includes a roof panel or a rear corner portion of a vehicle that is easy to receive radio waves and does not obstruct a driver's vision or interfere with safe driving. It is mainly installed on the quarter outer panel, etc., and the installation type is a method of being installed at an inclined angle at a predetermined angle in consideration of the upright type and the resistance of fluid (air).
[14] On the other hand, Figure 1 and Figure 2 is a perspective view and a longitudinal cross-sectional view for explaining a conventional antenna installed on the roof panel, the antenna 10 is an antenna rod 11 and the antenna rod 11 having a predetermined outer diameter and length It is composed of an antenna body 13 rotatably coupled via one end and the hinge 12 of the), the bottom of the antenna body 13 is a structure in which the assembly bolt 14 of a predetermined length is integrally coupled have.
[15] Therefore, the front end of the assembly bolt 14 is penetrated from the middle of the roof panel 1 located to the front side of the vehicle body to the interior side, and then assembled between the roof panel 1 and the roof rail panel 2. The antenna 10 is fixed to the roof panel 1 by screwing the assembly nut 15 to the tip of the bolt 14.
[16] At this time, the assembling nut 15 is inserted through the through hole 2a formed in the roof rail panel 2 to be screwed into the distal end of the assembling bolt 14.
[17] In addition, a headlining (not shown) is coupled to the bottom surface of the roof rail panel 2 positioned toward the interior to improve appearance.
[18] However, when the antenna 10 is installed on the roof panel 1 positioned to the front side of the vehicle body as described above, the entirety of the antenna 10 is caused by the air pressure rising through the window glass 3 during the high-speed driving of the vehicle. The part vibrates tremendously and generates driving noise, which causes a problem in that a radio wave reception state is not good.
[19] In addition, since there is no separate member for maintaining airtightness between the roof panel 1 and the antenna body 13, when the antenna 10 is shaken by air pressure during the high-speed driving of the vehicle, the assembly bolt ( 14) and a clearance (between) is generated between the roof panel 1, and rainwater or driving noise flows through the gap, thereby further reducing driving stability.
[20] Accordingly, the present invention has been made to solve the above problems, by installing an antenna in the middle portion of the roof panel located to the rear of the vehicle body, even if the vehicle is driving at high speed, it does not directly hit the air rising through the window glass Accordingly, an object of the present invention is to provide an antenna of a vehicle in which an antenna shaking due to air pressure is prevented as much as possible, and noise of a radio can be improved while minimizing driving noise.
[21] In addition, by installing the antenna on the roof panel by using an airtight member, it prevents the gap between the roof panel and the antenna during the high speed driving as much as possible, thereby reducing the running noise and bringing rainwater or foreign matter into the room. It is an object of the present invention to provide an antenna of a vehicle that can be prevented from entering.
[22] The antenna of the present invention for achieving the above object, the antenna body portion is coupled to the assembly bolt screwed through the roof panel from the indoor side to the outdoor side while being located at a predetermined portion of the roof panel located toward the rear of the vehicle body And a radio wave receiver configured to receive radio waves while being integrally formed with the antenna body.

[23] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[24] 3 is a perspective view of a vehicle equipped with an antenna according to the present invention, the antenna 30 according to the present invention is easy to receive radio waves as shown in Figure 3 does not obstruct the driver's field of view or interfere with safe driving, In addition, the vehicle body at a predetermined portion in the middle of the roof panel (1) located in the rear side of the vehicle body of the roof panel (1) in order to prevent the tremor phenomenon caused by the pressure of the air rising on the roof panel (1) during high-speed driving Will be installed at a certain angle to face the rear of the.
[25] That is, the antenna 30 according to the present invention is located at a predetermined portion of the roof panel 1 positioned toward the rear of the vehicle body as shown in FIGS. 4 and 5, and the roof panel 1 is moved from the indoor side to the outdoor side. It is composed of an antenna body portion 31 which is screwed and coupled to the assembly bolt 21 to penetrate, and a radio wave receiver 33 which is formed integrally with the antenna body portion 31 to receive radio waves.
[26] Here, the assembly bolt 21 is inserted into the space between the roof panel 1 and the roof rail panel 2 through the through hole (2a) formed in the roof rail panel 2, the driver (not shown) Through the roof panel (1) from the indoor side to the outdoor side of the vehicle by a tool such as the tip is coupled to the antenna body portion 31 by screwing.
[27] On the other hand, the bottom surface of the antenna body portion 31 has a structure in which a screw groove 31a for screwing the assembly bolt 21 is integrally formed.
[28] The antenna sealing member 35 integrally maintains the airtightness between the roof panel 1 and the antenna body 31 on the lower edge of the antenna body 31 in close contact with the roof panel 1. It is a structure that is joined by bonding.
[29] In addition, a headlining (not shown) is coupled to the bottom surface of the roof rail panel 2 positioned toward the interior to improve appearance.
[30] As such, when the antenna 30 according to the present invention is installed in the roof panel 1 positioned to the rear side of the vehicle body, the roof panel does not directly hit the air that rides up the window glass 3 during the high-speed driving of the vehicle. By hitting the air flowing along (1), the phenomenon that the antenna 30 according to the present invention tremble by the pressure of the air than the conventional antenna 10 described above with reference to Figs. As a result, the driving noise is reduced and the radio wave reception state can be stably improved.
[31] In addition, according to the present invention, the antenna body portion 31 is coupled to the roof panel 1 via the antenna sealing member 35, so that the antenna 30 vibrates minutely due to air pressure during high-speed driving. The gap between the roof panel 1 and the antenna body portion 31 can be prevented from being generated, which can further reduce driving noise and also prevent rainwater or foreign substances from entering the room. This can contribute to the luxury of the vehicle while improving the cleanliness of the room.
[32] As described above, the antenna according to the present invention is installed in a roof panel positioned at the rear side of the vehicle body together with the antenna sealing member, so that the running noise is reduced while the phenomenon in which the antenna is shaken by the air pressure during high-speed driving of the vehicle is reduced. As a result, the radio wave reception state of the radio is also stably improved, and the gap between the roof panel and the antenna body is sealed by the antenna sealing member, thereby preventing rain or other foreign substances from entering the room. Of course, as the cleanliness of the room is improved, there is an effect that can contribute to the luxury of the vehicle.
