Description

[Detailed Description of the Invention] The present invention relates to an antenna mounting device for detachably mounting an antenna on the bonnet, trunk lid, etc. of an automobile.

Traditionally, antennas installed at the rear of a car are installed by making a hole in the car body, but when the antenna is removed, the hole remains in the car body, which can cause rainwater to enter, and also spoils the aesthetics of the car itself. He was often shunned.

This invention allows for attachment and detachment without damaging the car body or trunk lid, etc. When the trunk is closed, the antenna can be securely fixed and cannot be removed by someone else. . Also, against the slope of the car body and trunk lid,
The antenna can be installed at a normal angle. Furthermore, when the trunk is opened, the main part of the antenna can be removed and stored in the trunk with a single touch, so it is a convenient antenna mounting mechanism that will not damage the antenna or the car body even when the car is washed in an automatic car wash. Examples of the present invention will be described in detail below.

FIG. 1 is a perspective view of an embodiment of the antenna according to the present invention, and FIG. 2 is an exploded perspective view. Figures 3a and 3b are diagrams showing the detailed structure. Note that although the antenna appears to be held upright in Figures 2 and 3b, the antenna itself is always tilted with respect to the mounting surface as described later, and depending on the viewing angle, , is depicted as if standing upright. First, in FIGS. 1 and 2, 1 is an antenna element part, 2 is a buffer spring, 3 is an upper holding metal fitting, 4 is a lower holding metal fitting and an antenna element tilt adjustment tool, and 5 is a main part of the antenna attached to an antenna support part 7. 6 is an antenna base which is inserted and fixed into a fitting part provided in the supporter part 7; 7 is an antenna which is fixed to the end surface of the trunk lid of the vehicle body and holds the antenna main part; This is the supporter department.

Next, the detailed structure will be explained using FIGS. 3a and 3b.

Antenna element 1 uses a frequency with a long wavelength.
For VHF, etc., a metal rod of 1/4λ or less is used, and if necessary, the outside of the rod is covered with plastic or the like. When the operating frequency is UHF or higher, an antenna of half-wave dipole or higher is formed, covered with plastic, and used while being electrically insulated from the buffer spring 2, holding fitting 3, etc.

The upper holding fitting 3 and the lower holding fitting 4 are coupled by a buffer spring 2, and the restoring force of the buffer spring 2 holds the antenna element 1 in a normal position. The holding fittings 3 and 4 are engaged with the inside of the buffer spring 2, and are firmly connected so as not to be separated by external force. The upper part of the lower holding fitting/antenna element tilt adjustment 4 has a shape obtained by cutting a cone obliquely, and has screw holes 4a (shown in FIG. 3B) for fixing the fixing plate 8 to the flat part of the bottom. ), and is fitted into the antenna base hole 6a at the bottom, and the angle between the supporter part 7 and the antenna with this hole 6a as the center of rotation, that is, the angle of inclination, is constant, but the inclination direction can make you turn your head in any direction,
It can be fixed to the antenna base 6 by a fixing plate 8. The tightening nut 5 is attached to the antenna base 6
The main part of the antenna is fixed to the antenna supporter part 7 by engaging with the antenna supporter part 7.The inner side of the contact part with the supporter part 7 is inclined in a conical shape, and the convex part of the supporter part 7 It is fitted with the portion 7b and can be fixed in a fixed position, and has a structure to prevent loosening.

The lower holding metal fitting/antenna element tilt adjustment tool 4 is
As shown in FIGS. 3a and 3b, it is connected to the antenna base 6 by a screw 9 and a fixing plate 8, and with the screw 9 loosened, the antenna can be tilted in any direction. When the screw 9 is tightened, the antenna base 6 and the lower holding metal fitting/antenna element tilt adjuster 4 are pressed together by the fixing plate 8, so that the tilt direction can be fixed. A hole 8a is bored in the center of the fixing plate 8, and a coaxial cable 10 communicates with the antenna element 1 through the hole 8a. On the other hand, the other end of the cable 10 is connected to a radio device. The cable 10 is also fixed to the antenna base 6 by a cable fixture 11 to prevent the coaxial cable 10 from being pulled out.

In addition, the antenna base 6 has a protrusion that is fixed to the supporter part 7 and prevents the antenna main part from coming off from the mating part of the supporter part 7 even if the tightening nut 5 is loosened when the trunk lid is closed. As shown in FIG. 4 and FIG.
It has a structure that allows you to enter. Further, the other end of the antenna base 6 has a projecting portion 6c that extends horizontally toward the rear fender of the vehicle and contacts the top surface of the fender, thereby preventing the antenna element 1 from rolling.

It is obvious that the larger the projecting portion 6c is, the more effective it is in preventing rolling.

Further, a rubber cushion 12 is added to the protruding portion 6c to protect the body paint and prevent unnecessary sound generation.

To explain the antenna supporter section 7 in more detail, the antenna supporter section 7 is attached to the end surface of the trunk lid, and the antenna main section is fitted and fixed thereto.

Therefore, when opening the trunk lid, the lid must be lifted together. The attachment of the antenna supporter section 7 to the trunk lid 16 is fixed by this U-shaped bent portion 7c.

Reference numeral 13 in FIG. 3 is a contact plate for preventing the trunk lid 16 from being damaged by the mounting screws 14 when the supporter 7 is installed. Further, 15 is a packing for preventing water leakage due to the cable 10 being caught between the trunk lid 16 and the rear fender groove, and is moved to an appropriate position on the cable 10 to prevent water leakage. It's summery.

As shown in FIG. 2, the supporter part 7 is provided with a U-shaped groove 7a into which the antenna base 6 is inserted, and at the bottom of the groove 7a there is a screw that engages with the conical internal slope of the tightening nut 5. It has a protrusion 7b that is intended to be automatically set to the optimum position by tightening. By having this protruding portion 7b, the peak portion and the internal mortar-shaped portion of the tightening nut 5 are firmly connected, and the main portion of the antenna can be firmly attached.

Next, when washing a car, etc., general car radio antennas have a structure in which the antenna part is stored inside the car body, whereas retrofitted antennas do not have an automatic expansion and contraction system. However, according to this invention, the main part of the antenna can be removed by opening the trunk and loosening the tightening nut, and the main part of the antenna can be removed inside the trunk. If the antenna is stored in the antenna, the car can be washed in the same way as a car without an antenna, and its handling is extremely simple and can be done in a short time.

As described above, according to the antenna mounting device of the present invention, it can be mounted to a mounting part such as a car trunk lid without any damage, and the main part of the antenna can be mounted and removed very easily. It has many advantages, such as the antenna cannot be removed when the trunk lid is closed and has an anti-theft function, and is particularly effective when used as an automobile antenna.
