Description
Technical field
The utility model relates to a kind of auto parts machinery, specifically refers to a kind of antenna for automobile.
Background technology
We know, the wireless devices such as communication, radar, navigation, broadcast, TV, all carry out transmission of information by radio wave, all need radiation and the reception of radio wave.In wireless device, be used for radiation and receive the device of radio wave and be called antenna.Antenna is for transmitter or provide required being coupled between receiver and the medium of radio waves propagate.Antenna+Transmitter, receiver are the same, are also important component parts of wireless device.Antenna is a kind of converter, and it is transformed into the guided wave of transmission above-the-line promotion the electromagnetic wave propagated in unbounded medium (normally free space), or carries out contrary conversion.Be used for launching or receiving electromagnetic parts in wireless device.The engineering systems such as radio communication, broadcast, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, every electromagnetic wave that utilizes carrys out transmission of information, all relies on antenna to carry out work.In addition, transmitting in energy with electromagnetic wave, the energy emission of non-signal also needs antenna.General antenna all has invertibity, namely both can be used as transmitting antenna with common antenna, also can be used as reception antenna.The same antenna is identical as the fundamental characteristics parameter of launching or receive.The reciprocity theorem of Here it is antenna.
Automobile also has antenna, and this antenna is mainly used for broadcast receiver.Applicant of the present utility model finds, car antenna of the prior art is directly fixed on roof.This structure in actual use, has the following disadvantages, and the angle of antenna can not adjust, when running car is to countryside, often can due to antenna towards away from signal station, and poor signal, there is very large noise in radio station.
Utility model content
The technical problems to be solved in the utility model is, provides one can auto-steering, the antenna for automobile that Received signal strength ability is stronger.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of antenna for automobile, and it comprises mast, antenna pedestal, sliding sleeve and electric expansion bar; Described antenna pedestal is installed on the roof of automobile, and the bottom of described mast is rotatably installed on antenna pedestal; Described electric expansion bar is installed on roof; The free end of electric expansion bar has been rotatably connected sliding sleeve, and described sliding sleeve is socketed in the bottom of mast; Described electric expansion bar is connected with remote control device, and described remote control device is installed on the driver control console of automobile.
As preferably, described mast is telescopic rod.
As preferably, described sliding sleeve is insulating case.
As preferably, the free end of described electric expansion bar is connected by rotating shaft with sliding sleeve; Bottom and the roof of described electric expansion bar are rotatably connected.
As preferably, described electric expansion bar carries storage battery.
After adopting said structure, the utility model has following beneficial effect: it comprises mast, antenna pedestal, sliding sleeve and electric expansion bar; Described antenna pedestal is installed on the roof of automobile, and the bottom of described mast is rotatably installed on antenna pedestal; Described electric expansion bar is installed on roof; The free end of electric expansion bar has been rotatably connected sliding sleeve, and described sliding sleeve is socketed in the bottom of mast; Described electric expansion bar is connected with remote control device, and described remote control device is installed on the driver control console of automobile.Can be controlled it at console by electric expansion bar structure to pull, when the poor signal of vehicle-mounted radio, by regulating the angle of antenna to obtain better signal after user can stop or slow down, the frequency of current radio is certain, so regulate antenna still to have certain effect when frequency is constant.Described sliding sleeve is that insulating case the signal of anti-anti-skid sheath and coupled electric expansion pole pair antenna can well cause interference.The free end of described electric expansion bar is connected by rotating shaft with sliding sleeve; Bottom and the roof of described electric expansion bar are rotatably connected.This structure can allow electric expansion bar better drive antenna to rotate.Described electric expansion bar carries storage battery.This structure can avoid automobile from roof cabling for electric expansion bar provides electric energy.
In sum, the utility model provides one can auto-steering, the antenna for automobile that Received signal strength ability is stronger.
Accompanying drawing explanation
Fig. 1 is the structural representation for the antenna of automobile in the utility model.
As shown in the figure: 1, mast, 2, antenna pedestal, 3, sliding sleeve, 4, electric expansion bar, 5, roof.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
By reference to the accompanying drawings 1, a kind of antenna for automobile, it comprises mast 1, antenna pedestal 2, sliding sleeve 3 and electric expansion bar 4; Described antenna pedestal 2 is installed on the roof 5 of automobile, and the bottom of described mast 1 is rotatably installed on antenna pedestal 2; Described electric expansion bar 4 is installed on roof 5; The free end of electric expansion bar 4 has been rotatably connected sliding sleeve 3, and described sliding sleeve 3 is socketed in the bottom of mast 1; Described electric expansion bar 4 is connected with remote control device, and described remote control device is installed on the driver control console of automobile.
