Abstract
The utility model discloses an antenna, which comprises an antenna slot, wherein an antenna is arranged in the antenna slot, a magnet is arranged on one end of the antenna, which is located outside the antenna slot, the magnetic pole direction of the magnet is same to the direction of an axis of the antenna, an electromagnetic coil is arranged on the antenna slot, the direction of the axis of the electromagnetic coil is same to the axis of the antenna, and two electrodes of the electromagnetic coil are connected with a switch of an applicable device. The antenna uses the electromagnet principle and the principle that same magnetic poles repel each other, thereby being capable of conveniently leading the antenna to be automatically popped and retracted, and being capable of preventing users from forgetting to extract the antenna to effect the using of devices. Simultaneously, the use experience feeling of users also can be increased through that the antenna is automatically popped and retracted.
Description
Technical field
The utility model relates to a kind of antenna, especially a kind of antenna that is suitable for having the mobile devices such as mobile phone of the function of televiewing.
Background technology
At present, along with the continuous development of the communication technology with popularize, to the application of the communication technology also more and more widely.Mobile device not only can communicate, and more can watch TV.For example Digital Video Broadcasting Handheld leaps to the popular visual field already.But, no matter be external DVBH (Digital Video BroadcastingHandheld, the handheld digital video broadcasting) standard still is CMMB (the ChinaMobile Multimedia Broadcasting in the current popularization of China, China Mobile multimedia broadcasting) standard all needs the user to extract television antenna out and just can watch.And the user in use forgets the extraction antenna through regular meeting, so that can't receive that signal can not watch.Some other has the electrical equipment of telescopic antenna, broadcast receiver for example, and also needing to extract antenna out in poor signal could use.The user needs to extract antenna out in use, opens two operations of switch; Also need off switch when closing, regain two steps of antenna.Troublesome poeration when it uses.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, cost is low, the antenna that can eject automatically during use.
In order to address the above problem, the utility model provides a kind of antenna, comprises a day wire casing, is provided with antenna in day wire casing, and described antenna is positioned at the outer end of day wire casing and is provided with magnet, and the pole orientation of described magnet and the axis of described antenna are in the same way; Described day wire casing is provided with solenoid, the axis of described solenoid axis and described antenna in the same way, two electrodes of described solenoid are connected on the switch of suitable device.
Further, described solenoid is arranged between described sky wire casing and the antenna.
Further, described solenoid is arranged on the described day wire casing outside.
Further, described solenoid is arranged on an end of close antenna upper magnet on the described sky wire casing.
Further, also be provided with reversing switch between the switch of described solenoid and described suitable device.
The principle that antenna of the present utility model utilizes the electromagnet principle and the magnetic pole same sex to repel each other can make antenna eject automatically and withdrawal easily, thereby can avoid the user to forget the use of extracting antenna out and influencing equipment.Simultaneously, the automatic ejection of antenna and withdrawal also can increase user's experience sense.
Description of drawings
Fig. 1 is the structural representation of antenna one embodiment of the present utility model;
Fig. 2 is the schematic diagram of antenna of the present utility model when being in the ejection state.
Among the figure: 1. day wire casing, 2. antenna, 3. magnet, 4. solenoid.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As shown in Figure 1, an embodiment of antenna of the present utility model comprises a sky wire casing 1 of being made by iron-bearing materials (or other can by the material of attraction), and the antenna 2 that can eject is arranged in this day wire casing 1.In the upper end of antenna 2, promptly be positioned at the end outside the antenna groove 1, be provided with a magnet 3, the N utmost point of magnet 3 makes progress, and S is extremely downward, and the axis of the direction of magnetic pole and antenna 2 is in the same way.Be provided with solenoid 4 near the part of upper end in sky wire casing 1 and between the antenna 2, the axis of solenoid 4 also with the axis of antenna 2 in the same way, two electrodes of solenoid 4 are connected respectively on the switch (not shown) of suitable device.The suitable device here is meant the equipment that antenna of the present utility model is installed, and can be mobile TV, also can be other equipment that needs antenna.
During use, open the switch of equipment, solenoid 4 energisings in opening device, solenoid 4 produces the magnet 3 opposite polarity magnetic force with antenna 2 upper ends, principle according to homopolar-repulsion, the magnetic force that solenoid 4 is produced promotes magnet 3 and moves upward, and magnet 3 drives antenna 2 and moves upward together, thereby ejects antenna 2 automatically.State after antenna 2 ejects as shown in Figure 2.
Behind the closing device switch, in closing device, solenoid 4 outages, solenoid 4 loses magnetic force, to the repulsive force disappearance of antenna 2 upper magnets 3.Because day wire casing 1 is by being made by the material of attraction, magnet 3 can produce attraction to sky wire casing 1, and under the effect of this attraction, magnet 3 drives antenna 2 withdrawals.
According to above-mentioned principle as can be known, the utility model can also carry out some changes to the foregoing description, and these are all within protection range of the present utility model.For example solenoid 4 is arranged on the outside of day wire casing 1; Also solenoid 4 can be arranged on the part of close lower end on day wire casing 1,, can realize the purpose of this utility model and effect equally owing to can be had the effect of magnetic conduction simultaneously by the material of attraction.Equally, if the N utmost point of magnet 3 and the exchange of the S utmost point also are fine, at this moment only need get final product, promptly as long as the polarity of solenoid 4 generations is opposite with the polarity of magnet 3 to solenoid 4 logical reciprocal electric currents.
The utility model can also be provided with a reversing switch (not shown) between the electrode of solenoid 4 and facility switching, be used to change the sense of current in the solenoid 4.Under the power connection state of solenoid 4, can change the sense of current in the solenoid 4 by reversing switch, thereby change the polarity of solenoid 4, make the polarity of solenoid 4 identical with the polarity of magnet 3, under the effect that heteropole is inhaled mutually, solenoid 4 attracts each other with magnet 3, thereby makes magnet 3 drive antenna 2 withdrawals.At this moment a day wire casing 1 must be by being made by the material of attraction.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection range of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection range of the present utility model.Protection range of the present utility model is as the criterion with claims.
