Problems solved by technology

[0004] This kind of rod-shaped antenna device is used in small electronic devices. When not in use, the antenna rod can be stored in the device body, and then pulled out for use. When pulling out the antenna rod, it is relatively smooth to pull out, and there will be no other problems. However, when the antenna rod is pressed in to store it, not only is it cumbersome, but also the storage is not smooth, and there are problems such as bending the antenna rod and easily breaking it.
[0005] In addition, in order to correspond to multiple frequencies, such a rod-shaped antenna rod must have a receiving range corresponding to each frequency in the axial direction, which makes the antenna rod longer and has the problem of occupying storage space.

[0079] in figure 1 In this, a notebook computer is represented by the symbol 1 as an example of a small electronic device with a wireless communication function. The notebook computer 1 is connected to the rear of the first housing 2 and the second housing 3 through the opening and closing device 4. The end can be opened and closed, the first housing 2 is provided with a keyboard, and the second housing 3 is provided with a display device.

[0080] The antenna rod 6 of the antenna device 5 of the present invention protrudes from the upper end of one side of the second casing 3 of the notebook computer 1. This antenna rod 6 is composed of a main antenna rod 7 and a sub antenna rod 8 in the middle. The sub antenna rods 8 are three, which are radially and inverted umbrella-shaped open around the main antenna rod 7. Next, the button element 9 constitutes the locking release means 11 of the slider 10, and its head 9a protrudes from the side of the second housing 3.

Abstract

The invention provides an antenna device for a small electronic device with wireless communication function, which allows one or more antenna rods to be accommodated in a device body by a single-touch operation during the accommodation of the antenna. The antenna device comprises a box, a sliding member, an antenna rod, a helical spring, and a locking-release means. The box is cylinder-shaped, has an open upper end part, and is accommodated in a shell. The sliding member is accommodated in the box, can slide in the superiorinferior direction without being pulled out from the upper part. The antenna rod is assembled on the sliding member, and can be accommodated in the box or protrude outside the box. The helical spring is tensionally disposed between one side of the sliding member and one side of the inner bottom of the box. The locking-release means is used to lock the sliding member at the side part of the box and release the sliding member from being locked at the side part of the box.

Description

Technical field [0001] The present invention relates to an antenna device, which is applied to notebook computers, personal digital assistants, other small electronic devices such as mobile terminals, with wireless communication functions or small electronic devices with wireless communication functions such as mobile phones . Background technique [0002] In recent years, not only mobile phones, personal digital assistants (Personal Digital Assistants), notebook computers and various other electronic devices such as mobile terminals have also been equipped with wireless communication functions, so that they can watch TV and perform network communications, such as Japan Special Publication 2009 The invention shown in Bulletin No. 159309 has gradually become popular. [0003] Such a small electronic device corresponding to wireless communication has an antenna device. As for this type of antenna device, rod-shaped antenna devices are widely used, such as those described in Japanes...
