Description

Technical Field

[0001] This invention belongs to the field of television antenna technology, specifically an outdoor television receiving antenna structure. Background Technology

[0002] A television antenna is a device used to receive wireless television signals. It captures electromagnetic waves in the air, converts them into electrical signals, and transmits them to a television set or set-top box to display television programs. Existing antennas typically consist of a metal vibrator, a matching circuit, and an output terminal, and are capable of receiving analog or digital television signals.

[0003] Some existing antennas include an element and a reflector. The reflector is used to enhance the antenna's directivity, reduce back-side interference, and focus electromagnetic waves onto the element. Therefore, during assembly, the assembler will first orient the antenna's reflector toward the direction of stronger electromagnetic wave energy, and then fix the reflector in place to prevent strong winds and other severe weather from interfering with the antenna and affecting signal collection. At this time, the direction of the reflector is relatively fixed relative to the direction of the TV's graphical interface. However, when a television is in motion, the orientation of its graphical interface changes constantly, which in turn causes the orientation of the reflector to change; or the electromagnetic wave energy changes direction due to environmental influences, which in turn requires readjusting the orientation of the reflector so that it is aligned with the direction of stronger electromagnetic wave signal intensity.

[0004] Therefore, it is essential to continue improving the existing antenna structure and design an antenna structure that can automatically adjust the antenna direction based on electromagnetic wave energy. Summary of the Invention

The frequency receiving module converts received electromagnetic wave signals into current and transmits them to the control module. The structure also includes a signal strength sensor, which transmits a strength signal to the control module.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Please refer to Figure 1-8 ; As is known, a television antenna is a type of radio antenna designed to receive terrestrial digital television, analog television, or other broadcast signals. Existing television antennas use a fixed dipole method. When the electromagnetic wave signal changes in strength and direction due to the influence of the surrounding environment, it is usually necessary to manually rotate the dipole, which is very inconvenient. Furthermore, the existing market has proposed an omnidirectional antenna structure to receive signals. Although this has solved the problem of changing the direction of the strength of dipole electromagnetic wave signals to some extent, the omnidirectional antenna has a circular radiation pattern, which cannot concentrate energy in a specific direction. It has low gain, is difficult to adapt to weak signal areas, and is easily affected by interference signals. It relies heavily on additional filters, resulting in low signal quality and failing to meet people's needs for a better life.

[0026] Implementation method 1: This invention provides an outdoor television receiving antenna structure to adapt to changes in direction and improve signal gain performance. Specifically, it includes a base 1 and a rotating module 2 rotatably connected to the base 1. The base 1 is made of high-strength aluminum alloy, possessing high wind and corrosion resistance, suitable for long-term outdoor use. The rotating module 2 is equipped with a control module 3 and a frequency receiving module 4, which are electrically connected. The frequency receiving module 4 converts the received electromagnetic wave signal into current and transmits it to the control module 3. The control module 3 is equipped with a signal strength sensor 10, which transmits the strength signal to the control module 3. The control module 3 generates control commands based on the signal strength and transmits the commands to the rotating module 2. The rotating module 2 adjusts the direction of the frequency receiving module 4 according to the control commands. The rotating module 2 can adjust the horizontal or vertical direction of the frequency receiving module. Furthermore, in this invention… In this embodiment, the rotating module 2 includes a fixed frame 21 and a turntable 22, which are rotatably connected. The fixed frame 21 is equipped with a rotating motor 23. In addition, the base 1 includes two support frames, each with a groove. The fixed frame 21 is slidably connected to the groove of the support frame and passes through the groove of the support frame. Screws are provided on the outside of the support frame to achieve a stable connection between the support frame and the fixed frame 21. The rotating motor 23 is located below the fixed frame 21 and is coaxially fixedly connected to the turntable 22 through the fixed frame 21. The rotating motor 23 is electrically connected to the control module 3. The rotating motor 23 drives the turntable 22 to rotate relative to the fixed frame 21. A deflection plate 24 is provided on the turntable 22 away from the fixed frame 21. The turntable 22 is fixedly connected to the deflection plate 24. A deflection component 25 is provided on the deflection plate 24 to adjust the angle of the frequency receiving module 4.

[0027] More specifically, the base 1 is first fixed in a suitable outdoor location. The signal strength sensor 10 receives and analyzes the changes in the direction of the strength of the surrounding electromagnetic wave signal and transmits the signal strength to the control module 3. The control module 3 generates a control command and sends it to the rotation module 2. The rotation module 2 rotates and adjusts the direction of the frequency receiving module 4 so that the frequency receiving module 4 faces the direction of the stronger signal, thereby enabling the frequency receiving module 4 to receive a stronger signal. Through the intelligent automatic rotation module 2 design, the intelligent rotation of the frequency receiving module 4 is realized, which significantly improves the signal reception performance and user experience. It perfectly solves the limitations of traditional fixed dipole 42 antennas and omnidirectional antennas, and meets people's needs for high-quality television signals and a better life.

[0028] When the control module 3 controls the rotating motor 23 to rotate, the rotating motor 23 drives the turntable 22 to rotate, which in turn drives the deflection plate 24 to rotate, which in turn drives the deflection component 25 to rotate, realizing the horizontal rotation of the frequency receiving module 4. The deflection component 25 is used to adjust the vertical rotation of the frequency receiving module 4, realizing the omnidirectional rotation of the frequency adjustment module to better adapt to different directions of electromagnetic wave strength.

[0029] In this embodiment, the deflection assembly 25 includes a deflection frame 251, a deflection motor 252 and a deflection block 253 are disposed on the deflection plate 24, the deflection motor 252 is mounted on the deflection plate 24 through a connecting block 254, and the deflection motor 252 is fixedly connected to the connecting block 254 by screws, the deflection frame 251 is an inverted U-shaped deflection frame 251, one end of the deflection frame 251 is coaxially fixedly connected to the output shaft of the deflection motor 252, and the other end of the deflection frame 251 is connected to the deflection block 253. The deflector block 253 is rotatably connected; furthermore, the deflector block 253 has a deflection groove 255, and a rotating shaft 256 is provided in the deflection groove 255. The rotating shaft 256 is rotatably connected to the groove wall of the deflection groove 255. The deflection frame 251 is coaxially fixedly connected to the rotating shaft 256. The control module 3 issues a command to control the deflection motor 252 to rotate. The rotation of the deflection motor 252 will drive the deflection frame 251 to rotate, thereby causing the frequency adjustment module located on the deflection frame 251 to rotate accordingly.

[0030] Implementation Method 2: Unlike Embodiment 1 described above, in this embodiment, the control module 3 includes a control box 31, which houses a dual-path filter 32, a matching unit 33, and an output unit 34. The frequency receiving module 4 includes an ultra-high frequency (UHF) receiving unit and a very high frequency (VHF) receiving unit. The UHF receiving unit includes six receiving elements 41 evenly arranged in a surrounding array, which are connected in parallel to form an output antenna array. The VHF receiving unit includes a dipole 42 that is matched to the antenna and connected to the control box 31. The signals received by the UHF and VHF receiving units are combined by the dual-path filter 32 and matched by the matching unit 33 before being output to the output unit 34. The VHF receiving unit captures electromagnetic wave signals and converts them into current. The signals are combined by the dual-path filter 32, and after filtering out interference signals, they are transmitted to the television equipment through the output unit 34. The signal strength sensor 10 analyzes the signal strength in real time and feeds it back to the control box 31. The control box 31 has a built-in MCU microprocessor. The MCU microprocessor generates control commands to drive the rotating motor 23 to rotate and adjust the direction of the frequency receiving module 4, aligning it with the direction of the strongest signal. Furthermore, an outer box 5 is fixedly installed on the deflection frame 251, and the control box 31 is located inside the outer box 5. Several elastic buckles 6 are provided on the first side wall of the outer box 5, and a clearance hole 7 is opened on the second side wall of the outer box 5 to facilitate the stabilization of the receiving vibrator 41 and the dipole 42.

[0031] Furthermore, the dual-channel filter 32 includes a first connection terminal and a second connection terminal. The first connection terminal is used to connect to the UHF receiving unit, and the second connection terminal is used to connect to the VHF receiving unit. The first connection terminal is electrically connected to the anode of a diode, the cathode of the diode is connected to an inductor L1, and the other end of the inductor L1 is electrically connected to an inductor L2. Capacitors C1 and C2 are grounded from both ends of the inductor L1, and inductor L2 is electrically connected to a resistor R1. Resistor R1 is electrically connected to a capacitor C3. The dual-channel filter 32 also includes a chip U1. The first receiving end of the chip U1 is electrically connected to the capacitor C3. The second receiving end of the chip U1 is provided with capacitors C4, C5, and C6 connected in series. The other end of capacitor C6 is electrically connected to the second connection terminal. The capacitor C5 is connected in parallel with grounded inductors L3 and L4. The output end of the chip U1 is electrically connected to the matching unit 33.

[0032] Other implementations that are the same as those in this implementation will not be described again in this implementation.

[0033] Implementation method 3, Unlike embodiment 2, the ring oscillator includes an elliptical segment 411 and a straight segment 412. One end of the straight segment 412 is connected to the elliptical segment 411 as an output terminal 1, and the other end of the straight segment 412 is connected to the control box 31 as an output terminal 2. Several stabilizing plates 8 are provided on the deflection plate 24. The stabilizing plates 8 are detachably connected to the deflection plate 24. The stabilizing plates 8 are provided with stabilizing slots 9 for the receiving oscillator 41 to be inserted. The stabilizing plates 8 are used to improve the stability of the receiving oscillator 41.

[0034] Other aspects that are the same as in Implementation Method 2 will not be described again in this implementation method.
