Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle antenna mounting device for mounting an antenna on a vehicle such as an automobile, and particularly to a mounting means for mounting an antenna inside a vehicle body.

[Conventional technology]

Generally, a vehicle antenna is attached to the outside of the vehicle body. Needless to say, it is desirable to mount the antenna on the outside of the vehicle body in terms of radio wave transmission and reception sensitivity. However, it is also true that if the antenna is attached to the outside of the vehicle body, it may become a target for theft or mischief. Particularly in the case of an extremely high frequency transmitting/receiving antenna equipped with an expensive transmitting/receiving set, there is a high possibility that not only the antenna itself but also the transmitting/receiving set installed inside the vehicle body may be stolen. However, until now, there was no appropriate means to mount an antenna inside the car body, and no consideration had been made as to how much the transmitting and receiving sensitivity would deteriorate if the antenna was mounted inside the car body. Antenna was not installed inside the car body.

[Problem that the invention attempts to solve]

As mentioned above, in the past, antennas were attached to the outside of the vehicle body, which could lead to theft or tampering, and it was difficult to take countermeasures against this. The inventors of the present invention considered mounting the antenna inside the vehicle body, and conducted various experiments to determine the extent to which the sensitivity decreases when an extremely high frequency transmitting/receiving antenna is mounted inside the vehicle body. As a result, they discovered that if the ultra-high frequency transmitting/receiving antenna is placed near the car window, the reduction in sensitivity is not so much of a problem in practice.

Therefore, the present invention allows the antenna to be easily and stably installed inside the vehicle body without causing a significant decrease in sensitivity and without special processing such as drilling holes.
It is an object of the present invention to provide a vehicle antenna mounting device that is extremely useful in preventing theft accidents and mischief.

[Means for solving problems]

In order to solve the above problems and achieve the purpose, the present invention takes the following measures. That is, a mounting base is provided which is placed on the rear deck of the vehicle and supports the vehicle antenna in an upright state, and one end is slidably connected to the mounting base and the other end is connected between the rear seat and the rear deck of the vehicle. A holding member is provided which is inserted into the rear deck and holds the mounting base in a predetermined position, and a removable close fixing member is provided which tightly fixes the mounting base to the surface of the rear deck so that at least no vertical movement occurs. .

[Effect]

By taking such measures, the following effects are achieved. In other words, the antenna can always be installed close to the window by sliding the mounting base and the holding member, thereby preventing a significant decrease in the sensitivity of the antenna. Moreover, since the antenna can be fixed by inserting the holding member and tightly fixing the fixing member, the antenna can be easily and stably mounted inside the vehicle body without special processing such as drilling holes. In this way, the antenna can be installed inside the vehicle body and can be removed at any time, which is extremely useful in preventing theft accidents and mischief.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention. In FIG. 1, reference numeral 11 is an extremely high frequency transmitting/receiving antenna, which is a non-grounded antenna having a matching device built therein. Reference numeral 12 denotes a mounting base that is formed to be able to be placed on a rear deck inside the vehicle body and supports the antenna 11 in an upright state. Reference numeral 13 denotes a feed line, one end of which is introduced into the mounting base 12 and connected to the feed point of the antenna 11. The other end of the power supply line 13 is connected to a transmitter/receiver set (not shown). 1
Reference numeral 4 denotes a holding member made of a material having appropriate elasticity such as synthetic resin, and one end of the holding member 4 extends from one end surface of the mounting base 12 to the mounting base 12.
It is inserted removably inside. This holding member 1
The other end of 4 is an insertion part 15 bent in a dogleg shape.
The surface of the insertion portion 15 is provided with a protrusion 16 that is easy to insert and difficult to remove. Reference numeral 17 denotes a removable close-fitting member fixed to the bottom of the mounting base 12.
As this close contact fixing member 17, a member called Magic Tape (trade name), which comes into close contact with the other party by a pressing operation, is suitable, for example. Note that depending on the conditions of the vehicle body, double-sided adhesive tape or a device equipped with a suction cup may be used. In any case, any material may be used as long as the mounting base 12 can be tightly fixed to the rear deck without drilling or the like in the vehicle body, and the mounting base 12 can be fixed at least so that it does not move up and down.

FIG. 2 shows the mounting base 12 and the holding member 14.
It is a figure showing a coupling mechanism with. As shown in FIG. 2, the insertion end of the holding member 14 is provided with a pair of legs 21 and 22 on both sides, and bulges 23 and 24 are provided on the outside of the tip of each leg 21 and 22, respectively. It is provided. On the other hand, inside the mounting base 12, there are engaging recesses 25 and 26 that engage with the bulges 23 and 24.
A space is formed on both sides. Thus, when the holding member 14 is inserted in the direction of the arrow, the bulges 23 and 24 engage with the engagement recesses 25 and 26 of the mounting base 12 due to the bending action caused by the elastic deformation of both legs 21 and 22. It is inserted while repeating withdrawal. If the insertion operation is stopped when the predetermined insertion degree is reached, the bulge 2 will be removed at that position.
3 and 24 and the engagement recesses 25 and 26 engage with each other,
Both are stably combined. In this way, the relative positional relationship between the mounting base 12 and the holding member 14 can be adjusted as appropriate.

FIG. 3 is a diagram showing a state in which a vehicle antenna is mounted inside a vehicle body using the above-mentioned antenna mounting device. As shown, the insertion part 1 of the holding member 14
5 is inserted between the back surface of the rear seat 31 and the rear deck 32. Then, the mounting base 12 is attached to the holding member 14 as shown by the arrow so that the antenna 11 stands upright at the position closest to the window 33.
The fixed member 17 is adjusted in position relative to the fixing member 17.
It is fixed to the surface of the rear deck 32 by.

According to this embodiment, the antenna 11 can always be installed close to the window by sliding the mounting base 12 and the holding member 14. Therefore, a significant decrease in sensitivity of the antenna 11 can be avoided. Moreover, the insertion operation of the insertion part 15 in the holding member 14 and the rear deck 3 by the fixing member 17

This embodiment is an example of application to a vehicle equipped with a rear seat 31' having a structure in which the top of the rear seat covers the upper surface of a rear deck 32. As shown in FIG. 4, in this embodiment, a flat holding member 14' having a step in the middle is used as the holding member, and one end of the holding member 14' is placed between the lower surface of the top of the rear seat 31' and the upper surface of the rear deck 32. I try to insert it between the two. Since everything other than the above is the same as that of the previous embodiment, the explanation will be omitted.

Note that the present invention is not limited to the above embodiments. For example, in the embodiment described above, the case where the extremely high frequency transmitting/receiving antenna 11 is used as the antenna is exemplified, but the present invention can be similarly implemented even when using other antennas. Further, in the above embodiment, as a sliding mechanism between the mounting base 12 and the holding member 14,
Although a structure in which the holding member 14 is inserted into the mounting base 12 is shown, the structure may be such that the sides of the mounting base 12 and one side of the holding member 14 are slidable. It goes without saying that various other modifications can be made without departing from the gist of the present invention.
