Abstract
The utility model relates to a telescopic aerial, comprising a shaft, an aerial main body and an aerial cap, wherein the shaft is arranged at the bottom of the aerial main body, the aerial cap is arranged on the top of the aerial main body, which includes a steel tube, a nickel-titanium alloy wire, an aerial main body shrapnel and a copper collar, wherein the nickel-titanium alloy wire is connected with the aerial cap. The shaft includes a metal case, a hinge, a shaft shrapnel, a rivet, a hinge connector, which are arranged in the metal case. The hinge is elastically contacted with the metal case through the shaft shrapnel fixed on the hinge and is movable relative to the metal case. The shaft is connected with the aerial main body through the hinge connector. The aerial of the utility model unfolds a state hinge to partially extend out of the metal case, and shrinks the state hinge to hide in the metal case. The length of the aerial is added under the condition that the shrink length of the aerial is unchanged, thereby greatly increasing radio frequency performance of the aerial.
Description
Technical field
The utility model relates to antenna, especially relates to a kind of telescopic antenna.
Background technology
Antenna requires antenna under user mode can be that the axle center rotates freely with the rotating shaft, and do not interfere with device housings, so must keep certain shaft length.But, in recent years, mobile terminal device such as mobile phone, notebook computer all develops towards miniaturization, multi-functional direction, and this just means and requiring antenna still to keep under the situation of radio-frequency performance preferably that the space of leaving the telescopic antenna of these mobile terminal devices for can be more and more littler.
At present, the rotating shaft of conventional telescopic antenna does not partly have metal shell, and the rotating shaft entire length all is the same in antenna contraction state and deployed condition, need take more antenna length space, the increase of antenna length of run is restricted, can't further improves antenna RF performance.
Summary of the invention
The purpose of this utility model is exactly to provide the telescopic antenna that a kind of antenna contracted length is constant, the antenna length of run improves, antenna RF performance strengthens for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of telescopic antenna, comprise rotating shaft, antenna body, antenna cap, described rotating shaft is located at the antenna body bottom, described antenna cap is located at the antenna body top, described antenna body comprises steel pipe, the Nitinol line, the antenna body shell fragment, copper ring, described Nitinol line is connected with antenna cap, it is characterized in that, described rotating shaft comprises metal shell, hinge, the rotating shaft shell fragment, rivet, hinge connector, described hinge, the rotating shaft shell fragment, rivet, hinge connector is located in the metal shell, described hinge is by being fixed on rotating shaft shell fragment on the hinge and metal shell Elastic Contact and can be with respect to the metal shell activity, and the described rotating shaft device that is connected through the hinge is connected with antenna body.
Described Nitinol line is connected with the antenna cap riveting.
The top of described metal shell is provided with reducing.
The middle part of described hinge is provided with raised step.
Described rotating shaft shell fragment is the cydariform shell fragment.
Described hinge connector is provided with raised step.
The described rotating shaft device that is connected through the hinge is connected with the antenna body roll extrusion.
Compared with prior art, the utlity model has following advantage:
1. shaft length is short when the antenna contraction state compares in the antenna deployed condition, antenna integral body has increased the length of antenna body under the constant condition of contracted length, simultaneously because antenna body has plurality of sections of steel pipes and Nitinol line, so the length of run of antenna increases greatly, improved the radio-frequency performance of antenna;
2. on the hinge shell fragment is installed, makes between hinge and the metal shell to have elastic force, strengthened the useful life of antenna, and the feel when making the antenna drawing is good, and can guarantee that signal reliably conducts;
3. simplify the structure of rotating shaft part, made the easier control of production process, reduced production cost.

Embodiment
The utility model is described in further detail for the contrast drawings and the specific embodiments below.
As Fig. 3～shown in Figure 8, a kind of telescopic antenna, comprise rotating shaft 1, antenna body 2, antenna cap 3, described rotating shaft 1 is located at antenna body 2 bottoms, described antenna cap 3 is located at antenna body 2 tops, described rotating shaft 1 comprises metal shell 11, hinge 12, cydariform rotating shaft shell fragment 13, rivet 14, hinge connector 15, described antenna body 2 comprises steel pipe, Nitinol line, antenna body shell fragment, copper ring, described rotating shaft 1 device 15 that is connected through the hinge is connected with antenna body 2 roll extrusion, and described Nitinol line is connected with antenna cap 3 rivetings.
The hinge 12 of rotating shaft 1, cydariform rotating shaft shell fragment 13, rivet 14, hinge connector 15 is located in the metal shell 11, the top of described metal shell 11 is provided with reducing 16, described hinge 12 by be fixed on the hinge 12 cydariform rotating shaft shell fragment 13 and metal shell 11 Elastic Contact and can be with respect to metal shell 11 activities, hinge 12 can be hidden in the metal shell 11 fully during the antenna contraction state, hinge 12 can partly stretch out metal shell 11 during the antenna deployed condition, the middle part of described hinge 12 is provided with raised step 17, and described hinge connector 15 is provided with raised step 18.
Rotating shaft 1 is arranged at the antenna bottom, after antenna launches, antenna body 2 can be that the center rotates freely with rotating shaft 1, reducing 16 is arranged at the top of the metal shell 11 of rotating shaft 1, there is raised step 17 at hinge 12 middle parts, and hinge 12 can not pulled out metal shell 11 fully when antenna was launched, and hinge connector 15 has raised step 18, when making day linear shrinkage, metal shell 11 is at these raised step 18 place's stop bits; Cydariform shell fragment 13 is installed on the hinge 12, is made between hinge 12 and the metal shell 11 to be in the Elastic Contact state all the time, strengthened the useful life of antenna, and the feel when making the antenna drawing is good, and can guarantee that signal reliably conducts.
