Abstract
The utility model discloses a television antenna with direction-auto control unit, which belongs to products of a domestic appliance. The utility model is composed of a speed variator, an aerial rotation controller, and an aerial revolving azimuthal displayer. The utility model can remotely control the rotation of the antenna, display the value of the change in direction on the displayer at any time, and make the antenna be conveniently adjusted to the optimum receiving direction. The television antenna with direction-auto control unit can be used to the places with a plurality of television channels. Every television channel can obtain the optimum receiving effect. The circuits and the machine have the advantages of simple structure, low cost, and convenient use.
Description
The invention belongs to the radio products in the household electrical appliance.
Along with increasing of television channel, people wish all can obtain the optimum reception effect to the TV signal that is in different directions.
Before the present invention works it out, the TV receiving method that satisfies above-mentioned requirements has two kinds, the first is provided with the TV programme that plurality of antennas receives different orientations respectively, and this method is installed complicated, expensive and will plug corresponding antenna when channel change, makes troubles to use.Another kind method is to make one pair of antenna rotate the TV programme of watching different azimuth with tumbler.Introduced this method in " television receiving antenna " book that the People's Telecon Publishing House publishes in October, 82.Though the available one pair of antenna of this method receives multi-channel programme, when far distance controlled is rotated, can't know that antenna rotates the azimuth at place, back, so when converted channel, often need to adjust repeatedly, use inconvenient.
Automatically the television receiving antenna that turns to provided by the present invention can overcome above-mentioned weak point.
Systematic schematic diagram of the present invention as shown in Figure 1.
The summary of Fig. 1 principle: by antenna pivoting controller (1) control motor D rotating, motor D drives full channel tv receiving antenna (4) through gearbox (3) and detects potentiometer W with corner
2Rotate potentiometer W simultaneously
2Voltage between travelling arm and the detection power supply E negative pole is connected to the two ends of antenna azimuth display list V, forms the antenna azimuth display.When antenna (4) is in different azimuths, potentiometer W
2Travelling arm and detection reference power cathode between have different potential values, so display list V can demonstrate the residing azimuth of antenna (4) exactly.
Mechanical rotation sketch of the present invention as shown in Figure 3.
Make the main transmission principle of the gearbox (3) that antenna (4) rotates such as following: motor D is rotated its power and is made antenna (4) rotation that is fixedly connected on the output shaft (12) by gear (14), gear (8), rotating shaft (9), worm screw (10), worm gear (11), output shaft (12) successively.
Make corner detect potentiometer W
2The transmission principle of motion such as following: motor D is rotated, and its motion makes corner detect potentiometer W by gear (14), gear (8), rotating shaft (9), worm screw (10), worm gear (11), gear (13) successively
2Rotate synchronously with antenna (4).
Advantage of the present invention is can be installed in outdoor antenna in indoor remote control to rotate, and orientation and bearing variation value that antenna is rotated show on display list at any time, and be so that antenna is adjusted to best receive direction easily, easy to use.Because the present invention replaces the function of plurality of antennas with one pair of antenna, make it to spend less, install simply; And because circuit structure of the present invention is simple, good reliability.
Fig. 1 is for turning to the systematic schematic diagram of television antenna automatically.
Fig. 2 is for turning to the basic circuit schematic diagram of television antenna automatically.
Fig. 3 is for turning to the machine driving sketch of television antenna automatically.
For the concrete use-case of setting forth, the basic circuit with Fig. 2 is that example is illustrated below.
In Fig. 2, motor D selects the phonograph special DC motor for use.Detect potentiometer W
2Selecting resistance for use is the WTX molded lines potentiometer of 1K Ω.The azimuth display list is selected the 69C of 0～3.5V range for use
4-V-type voltmeter.The also available electrical equipment display element that other can demonstrate electric quantity change replaces voltmeter.Detection reference power supply E is by winding IV, silicon rectifier stack DZ, the resistance R of transformer BK
2, voltage-stabiliser tube ZW forms.The antenna pivoting controller is by Transformer Winding I, II, rectifier diode Z

2, can make motor D forward or reverse.Motor D drives all channel antenna and antenna azimuth detection potentiometer W through reduction box
2Regulating shaft rotate simultaneously, if when forwarding antenna to the inverse clock extreme position, potentiometer slider moves to topmost, if suitably select voltage stabilizing value and the R of ZW
1With W
2Voltage ratio, can make the clock of antenna azimuth display list V reach the position of 3.5 volts of full scales, promptly show the maximum azimuth of antenna 350 degree.In like manner, when antenna forwarded the clockwise extreme position to, the cursor slide of potentiometer moved to bottom, and at this moment, the both end voltage of potentiometer is zero, and zero position is got back in the indication of voltmeter, showed the minimum azimuth of antenna zero degree.
Technical parameter is as follows:
Angle range: 0～350 °.
The corner index error:＜5%, rotating speed: 10 rev/mins.
