Description

Positioning Mechanism for Retractable Antenna

technical field

The utility model relates to an antenna positioning technology, more specifically, relates to a positioning mechanism applied to a retractable antenna in an electronic device.

Background technique

With the continuous development of communication technology and the continuous change of consumer demand, wireless network has become an important direction for the development of modern information industry by virtue of its very convenient connection mode, which enables people to search for network resources anytime, anywhere and at will. And it has become very popular in the life and work of modern people. Correspondingly, wireless network equipment has also developed rapidly under this favorable situation. The most common electronic devices such as notebook computers, mobile phones, and personal digital assistants (PDAs) , all have wireless network function.

In order to enhance the effect of wireless transmission and reception, this type of electronic device has an antenna device for transmitting and receiving signals, and with the emergence and rapid popularization of the third generation (3G) communication technology, existing devices such as notebook computers, mobile phones, personal digital The electronic device of the assistant will correspondingly have a 3G antenna.

The 3G antennas of existing electronic devices can be roughly divided into two types: built-in and external. Among them, since the built-in 3G antenna is installed inside the electronic device, it is basically invisible, and has poor receiving ability and poor signal coverage. The poor problem, once the environment where the signal is bad, it can hardly work normally; in comparison, the external 3G antenna is exposed to the shell of the electronic device, which has relatively strong reception and signal coverage capabilities. Therefore, based on the dramatically increased signal transmission volume required by 3G communication, manufacturers are more inclined to produce electronic devices with external 3G antennas.

Please refer to FIG. 1 , which is a three-dimensional schematic diagram showing that an external 3G antenna is installed on an electronic device such as a notebook computer, and the 3G antenna is a retractable antenna. As shown in the figure, the retractable antenna 11 is arranged on the top cover of the display 10 of the notebook computer 1 , and the retractable antenna 11 can be pushed out when it is to be used. Please refer to FIG. 2A and FIG. 2B together, wherein FIG. 2A is a schematic perspective view showing a bottom view of an antenna unit of a conventional telescopic antenna; FIG. 2B is a schematic top view of an antenna base of a conventional telescopic antenna. As shown in the figure, the retractable antenna 11 includes an antenna unit 110 and an antenna base 112, wherein the antenna unit 110 is used to receive 3G signals, and has first guides 1101 located on both sides; the antenna base The seat 112 is fixed on the display 10 of the notebook computer 1 and has a second guiding portion 1121 corresponding to the first guiding portion 1101 .

However, when using the retractable antenna 11, since there is no positioning mechanism during the process of extending or retracting the antenna unit 110, it is impossible to provide the user with hints such as hand feeling. When the antenna unit 110 is pushed, it is not easy to feel It is easy to directly push the antenna unit 110 from the antenna base 112 to see if it has been pushed to the maximum. Similarly; when intending to retract the antenna unit 110 to hide it in the antenna base 112, it is not easy to feel whether the antenna unit 110 has been completely retracted.

In addition, since the antenna unit 110 and the antenna base 112 are positioned only by the first guide portion 1101 and the second guide portion 1121 clamped to each other, when extending and retracting the antenna In the process of unit 110, they all have the same feel and the same resistance, and cannot achieve stable positioning. Moreover, if conditions such as vibration or tilt occur, the position of the antenna unit 110 in the antenna base 112 will change without a positioning mechanism, which will affect the effect of receiving signals.

Therefore, how to find a positioning mechanism for a retractable antenna, which can provide a sense of touch and prevent the antenna from falling out during operation, and stably position the antenna unit in the antenna base, so as to overcome the above-mentioned various defects, is currently a problem.
