[Industrial applications]

 The present invention relates to a structure of an antenna storage method for a wireless communication device.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a small portable radio communication device is often used in which the antenna is housed in the housing or folded along the housing when not in use.

FIG. 4 shows an antenna mounting structure for housing the antenna inside a housing. In the figure, reference numeral 1 is a main body of the wireless device, and 2 is an antenna. Reference numeral 6 denotes a holder, on which the antenna 2 is slidably supported. The antenna 2 is a whip antenna, and a sleeve 5 is fixed to the lower end of the antenna 2. A cap 9 is fixed to the upper end, but no sleeve is provided. The holder 6 is composed of a first holder portion 7 fixed to the top plate 1a of the radio main body 1 and a second holder portion 8 screwed thereto. A drip-proof O-ring 10 is incorporated on the inner peripheral side between the holders 7 and 8.

The O-ring 10 and the antenna 2 are in contact with each other during the process of pulling out and pushing in the antenna 2 as well as in the state of FIG. 4 in which the antenna 2 is housed and the state of FIG. A drip-proof structure is provided between the holder 6 and the holder 6, and raindrops can be prevented from entering the inside of the radio main body 1 by traveling along the surface of the antenna 2. A drip-proof O-ring 11 is also incorporated between the first holder portion 7 and the top plate 1a. Reference numeral 12 is a simple locking mechanism, which is composed of a substantially U-shaped spring 13 incorporated in the first holder 7. This engages with the annular groove 9 b of the thick portion 9 on the lower side of the cap 9. The spring 13 is fitted and incorporated in an annular groove 7a formed on the inner peripheral surface of the first holder 7, and the inward curved portions 13a and 13b of the arms of both sides are arranged at the first and second positions. No. 1 holder part 7 projects into the central opening 7. The spring 13 is slightly biased and biased in a direction in which it spreads, and is incorporated in the annular groove 7a without rattling. Further, the sleeve 5 is dimensioned to fit in the leaf spring portion 8a of the second holder portion 8.

When the antenna 2 is pushed into the radio main body 1 to the final position, the large diameter portion 9a of the lower portion of the cap 9 is fitted into the central opening 7b, and the annular groove 9b is engaged with the curved portions 13a and 13b. However, the antenna 2 is simply locked in this position. As a result, the antenna 2 is prevented from being unnecessarily pulled out while being carried.

Further, a small collision when the annular groove 9b is engaged with the curved portions 13a and 13b is transmitted to the user's fingertip, and the user can feel that the antenna 2 is completely stored. When the antenna 2 is completely pulled out, the tip of the leaf spring portion 8a engages with the groove 5a and is simply locked, as shown in FIG.

On the other hand, as a rod antenna device for a portable radio, it is generally known that a rod antenna element is attached to a required position of a housing of a set and the rod antenna element can be tilted at that position as shown in FIG. Has been. The mounting base of this rod antenna has a structure as shown in FIG. That is, a ball 17 for tilting rotation is provided at the lower end of the multistage telescopic rod 2, and the ball 17 is integrally connected to the bolt 8 and is enclosed by an outer cylinder 18 which is combined with the bolt 8. The structure is such that the compression spring 19 strongly holds and biases the outer cylinder 18. For this reason, even if the inclination of the rod antenna 2 is freely changed, the rod antenna 2 is fixed at that position and its weight does not change its direction.

[0008]

[Problems to be solved by the device]

 When installing the antenna according to the conventional technology, the antenna can be stored when it is no longer needed.As described above, the antenna can be stored in the housing, and the antenna can be folded along the housing and the direction of the antenna can be freely changed and fixed when in use. There is a way to do it. An object of the present invention is to provide an antenna housing structure in which an antenna of a wireless communication device is housed in a housing when not in use, pulled out when used, and the antenna is oriented in an arbitrary direction.

[0009]

[Means for Solving the Problems]

 An antenna and an antenna mechanism of a wireless communication device having a storage part for storing the antenna in the wireless communication device main body are mounted on the wireless communication device main body with a rotating part in which the antenna is inserted close to the entrance of the storage part. When the antenna is pulled out from the housing of the wireless communication device and the lower end of the antenna is housed in the rotating part, the rotating part holds the antenna, and when the antenna is oriented in any direction, it is fixed and maintained in that direction. Antenna structure.

【Example】

 FIG. 1 is a front view and a side view of a wireless communication device according to the present invention with an antenna housed therein. In the figure, reference numeral 1 is a main body of a wireless communication device, which is provided with a storage part capable of storing an antenna. The storage unit is not limited to the one having a sliding cylinder that is separated from the circuit of the wireless communication device or the one having an air space in which the antenna can be stored in the circuit unit of the wireless communication device. Further, in the state where the antenna is stored, the antenna is fixed and held by a conventional technique (not shown) so as not to slip out or rattling, but the means is not limited.

FIG. 2 is an external view of the antenna according to the present invention set to a communication state. That is, when the antenna 2 is pulled out from the housing portion of the wireless communication device 1 and the lower end portion of the antenna 2 is housed in the rotating portion 3, the antenna 1 is held by the rotating portion 3 and can be held only when a certain force is applied. Can be solved. The holding means of the prior art are sufficient.

FIG. 3 is an external view showing a means for changing the direction of the antenna according to the present invention. With the lower end of the antenna 1 housed and held in the rotating part 3, the antenna 1 can be arbitrarily changed in the direction of about 180 ° as shown in the figure. Also, at this time, it is equipped with means for keeping the direction fixed even if it is oriented in any direction. Further, the rotating portion 3 is also equipped with electrical relay connection means so that the antenna 1 can be connected to the antenna side of the radio communication device circuit regardless of the direction in which the antenna 1 faces. Any technology can be used without particular limitation.

Next, when communication is completed and the antenna is to be housed, the antenna 1 is rotated, and the antenna is pushed in at a position where the lower end of the antenna 1 faces the entrance / exit of the antenna housing part of the main body of the wireless communication device. For example, the antenna can be stored in the wireless communication device.

[0014]

[Effect of device]

 Since the antenna storage structure of the wireless communication device according to the present invention is provided with the rotating part 3, the retractable antenna can be pulled out and used only when necessary, and the antenna can be rotated and fixed in any direction by the rotating part. The practical effect is great.
