Technical Field
[0001] The invention relates to the technical field of antenna components, in particular to a dual-broadband spotlight antenna. Background Art
[0002] Dual-broadband spotlight antenna is a design that builds the antenna into the spotlight, mainly used for signal coverage. Existing spotlight antennas are mainly divided into two types: ordinary spotlight antennas and wide-angle spotlight antennas. The vertical beam width of the wide-angle spotlight antenna is larger, while the vertical beam width of the ordinary spotlight antenna is smaller. This larger vertical beam width makes the wide-angle spotlight antenna more suitable for vertical coverage of high-rise residential areas. Therefore, the wide-angle spotlight antenna is more suitable for high-rise buildings with 25 to 35 floors, mainly to enhance the field strength of the middle and upper floors, while the ordinary spotlight antenna is suitable for low-rise buildings or medium-height buildings.
[0003] As urbanization continues to advance, there are more and more high-rise buildings, and the demand for signal coverage is becoming more and more intensive. In the face of high-rise buildings, operators usually use wide-angle spotlight antennas to cover the building with network signals. However, due to the large radiation range of the wide-angle spotlight antenna, it is easy to have unreasonable indoor signal coverage during the installation process, and it is easy to have serious signal leakage to the outdoors. In areas with dense high-rise buildings, this phenomenon is prone to pilot pollution, which in turn affects the signals of surrounding buildings. In addition, since the signal leakage to the outdoors is serious, it is easy for external users to occupy the signal, resulting in indoor users being unable to access the Internet and unable to make normal calls.
[0004] In response to the above-mentioned problems, some solutions are provided in the prior art. For example, as mentioned in the journal "Ni Shihua, Wang Lin. A solution to solve the problem of outdoor indoor signal leakage to achieve cost reduction and efficiency improvement - DL antenna hard modification solution [J]. Communication Management and Technology, 2020, (06): 56-59.", in response to this problem, the solution adopts the method of re-drilling the vibrator base and adjusting the position of the vibrator base before installation. However, although the prior art adjusts the signal radiation range of the spotlight antenna to high-rise buildings by adjusting the vibrator base, it only flips the radiation range of 60 degrees horizontally and 30 degrees vertically by 90 degrees to make it a signal radiation range of 30 degrees horizontally and 60 degrees vertically. In essence, there is no adaptive adjustment for the height and width of the building that needs signal coverage, and it cannot adapt well to buildings of different sizes. In addition, the adjustment method of the prior art requires re-drilling the installation position of the vibrator base according to the measurement results. The operation steps are relatively cumbersome and rely more on the proficiency of the workers. Therefore, the efficiency of installing and adjusting the spotlight antenna is low.
[0005] Therefore, a dual-broadband spotlight antenna is proposed to solve the problems that the radiation range of the existing spotlight antenna is not convenient to adjust, resulting in poor adaptability to buildings of different sizes and low efficiency of installation and adjustment. Summary of the invention
[0006] The purpose of the present invention is to provide a dual-broadband spotlight antenna, which solves the problems of complicated adjustment steps, low installation efficiency and limited signal transmission when adjusting the radiation range of the spotlight in the face of buildings of different heights. This scheme uses a first adjustment component to adjust the angle of two broadband vibrators relative to the inner circle of the mounting plate, and uses a second adjustment component to place the broadband vibrators on a radius line from the center of the mounting base to the outer circle, and the distance between the two broadband vibrators and the center of the circle can be adjusted along the radius line. Through the coordination of the angle of the broadband vibrator in the spotlight and the spacing between the two broadband vibrators, it can be quickly adapted to existing buildings and gain signal transmission, while accelerating the adjustment speed and improving work efficiency.

[0009] Through the above scheme, the mounting plate is fixed inside the outer cover to serve as a base, and the first adjustment component is rotated on the mounting plate to adjust the angle of the two broadband oscillators inside the spotlight, thereby controlling its radiation range, and the broadband oscillator is placed on a radius line from the center of the mounting seat to the outer circle through the second adjustment component, and the distance between the two broadband oscillators and the center of the circle can be adjusted along the radius line to further adjust the radiation direction, and the standing wave ratio can be optimized by adjusting the spacing between the two oscillators, thereby improving the performance and efficiency of the transmission system; this adjustment method enables workers to quickly adapt to buildings of different sizes and heights, so that the radiation range is closer to the shape of the target building, reducing signal leakage and pilot pollution, improving installation and adjustment efficiency, and having a gain effect on signal transmission.
[0010] Preferably, the mounting plate is provided with a plurality of reflective strips at the edge near the first adjustment component, the reflective strips are all located in the front half of the mounting plate, the vertical cross-section of the reflective strip is a right triangle with the hypotenuse facing the top of the first adjustment component, the reflective strip is made of plastic as a whole, and the material of the hypotenuse surface is aluminum, the number of the reflective strips is 36, including 5 long reflective strips and 31 short reflective strips, a long reflective strip is provided after every 5 reflective strips, and the angle between each of the reflective strips is 6 degrees.
[0011] Through the above scheme, since each reflective strip is arranged at a certain angle, workers can know the adjustment angle more clearly when adjusting the two broadband oscillators in the spotlight, so as to reduce the adjustment error. In addition, the tips of the reflective strips all point to the mounting base, and can cooperate with the protrusions on the mounting base to indicate the rotation angle. In addition, since the office floor height is generally four meters, in order to avoid the boundary of the spotlight radiation range only covering half of a certain floor, or in other words, not completely covering a certain floor, which will easily cause the signal to be poor and the network to be poor on the floor that is not completely covered, therefore, in this scheme, the angle between each reflective strip corresponds to the floor height of the building, and the angle difference between the two reflective strips is taken as a unit, so that the radiation range of the spotlight antenna can be increased or reduced by four meters when the angle is adjusted by one unit.
[0012] In addition, the surface material of the reflection strip close to the wideband oscillator is aluminum, and the inclination angle of the inclined surface is the same as the inclination angle of the hypotenuse of the mounting base, so that it has the function of reflecting and beaming signals, making the signal more concentrated and the main lobe signal energy stronger, thereby avoiding signal leakage. In addition, the main material of the reflection strip is plastic, which makes it lower in cost and can also avoid interference caused by other directions of the reflection strip facing the signal.

[0014] Through the above solution, the broadband oscillator can be adjusted 180 degrees in the spotlight, thereby adjusting its radiation angle. The slide rail is made of smooth material to make the adjustment of the first adjustment component smoother and provide a better user experience.
[0015] Preferably, the outer ring of the arc-shaped slide rail of the mounting plate is provided with a locking groove 1 having the same shape as the arc-shaped slide rail, and the surface of the locking groove 1 is a thermoplastic rubber coating.
[0016] Through the above scheme, the first adjustment component can be fixed by friction under the action of the locking groove 1, the thermoplastic rubber coating has good friction, and it can maintain its performance within a wide temperature range. Since the internal temperature of the spotlight will increase during use, this material can maintain its due function for a long time, ensuring the service life of the equipment.

[0018] Through the above scheme, the mounting seat is processed into a disc shape with an inclined and raised edge, and because the mounting seat is made of aluminum plate, it can reflect the signal toward the center line of the mounting seat, which has the effect of bundling the signal and enhancing the main lobe signal energy, thereby reducing the dispersion and leakage of the signal, and the upper edges of the through slots 1 and 2 on the mounting seat are both chamfered upward, so that they can also have the effect of reflecting the signal. At the same time, the chamfers of the edges of the through slots 1 and 2 are provided with multiple embedded trapezoidal multi-faceted reflection structures, so that the signal can be reflected multiple times after contacting it, thereby achieving the effect of enhancing signal strength, gaining signal transmission, and bundling and enhancing the main lobe signal energy.
[0019] Preferably, the first adjustment component also includes a slider, an extension plate 1, a gasket and a locking bolt 1, the slider is fixed to the left side of the mounting seat, the slider is L-shaped and arranged in the slide rail, the contact positions of the slider and the slide rail are both arc-shaped structures, the extension plate 1 is connected to the slider, the gasket is arranged on the upper side of the extension plate 1, and the locking bolt 1 is connected to the extension plate 1.
[0020] Through the above scheme, the contact area between the slider and the slide rail is reduced, so that the resistance when the mounting base rotates relative to the mounting plate is smaller. In addition, the upper end of the L-shaped slider extends to the top of the mounting plate and cooperates with the locking bolt through an extension plate. When adjusted to a suitable position, the locking bolt is tightened to squeeze it with the locking groove to fix it, so that the position of the wide-band oscillator can be repeatedly adjusted without re-drilling, thereby improving efficiency.
[0021] Preferably, the mounting seat is provided with a plurality of dimensional stripes, and the dimensional stripes include long stripes and short stripes.
[0022] Through the above solution, the arranged stripes can more clearly show the adjustment distance between the two broadband vibrators, making the adjustment process more convenient and accurate.
[0023] Preferably, the second adjustment component includes a fixed plate, a movable plate, a conductive sheet, a rack, a limit block, an extension plate 2, a locking bolt 2, a connecting block, a baffle, a connecting column 1, a connecting column 2, a slide groove and a limit groove. Except for the extension plate 2 and the locking bolt 2, the above parts are provided with two groups and are all centrally symmetrically arranged about the center point of the mounting seat. The connecting column 1 and the connecting column 2 are respectively slidably connected to the through slot 1 and the through slot 2. The fixed plate is fixed on the connecting column 1 and the connecting column 2. The extension plate 2 is connected to the front side of the connecting block on one side. The extension plate 2 is soft rubber. The rack is made of rubber material, the second locking bolt is connected to the second extension plate and is connected to the limit groove, the movable plate is connected to the fixed plate, the conductive sheet is connected to the fixed plate, the connecting block is fixed on the lower side of the first connecting column and the second connecting column, the slide groove and the limit groove are arranged on the connecting block, the baffle is fixed to one end of the rack, and the other end of the rack away from the baffle is connected to the connecting block, the above-mentioned rack is slidably connected in the slide groove of another group of connecting blocks arranged symmetrically around the center, the limit block is connected to the rack, and the middle part of the two groups of racks is meshed with gears, and the gears are rotatably connected to the bottom of the mounting seat.
[0024] Through the above scheme, the second adjustment component is composed of two groups of parts arranged symmetrically with respect to the center. Under the action of the gear and the racks on both sides thereof, the worker only needs to adjust the position of one of the broadband oscillators to synchronously adjust the other one during adjustment, thereby avoiding the problem of deviation in the radiation range caused by different distance adjustments of the two broadband oscillators, thereby making the adjustment efficiency of the broadband oscillator higher.
[0025] Preferably, the second adjustment component also includes an installation groove, a sliding rod and a spring. The installation groove is arranged on the fixed plate. The sliding rod is slidably connected to the installation groove. One end of the sliding rod is fixedly connected to the movable plate. The spring is located in the installation groove. Both ends of the spring are respectively connected to the sliding rod and the installation groove.
[0026] Through the above scheme, the movable plate is slidably connected to the fixed plate and connected by a spring, so that when installing the broadband vibrator, there is no need to perform drilling as in the traditional installation method. This scheme only requires one end of the broadband vibrator to be placed on the movable plate and pushed away from the fixed plate. When the distance between the movable plate and the fixed plate is sufficient to place the broadband vibrator, it can be put down. At this time, the movable plate clamps the broadband vibrator under the action of the spring to prevent it from falling, so that the device can achieve the installation and fixation of the broadband vibrator more quickly, and can also facilitate the replacement of the broadband vibrator, thereby improving the work efficiency of workers.

[0029] Compared with the prior art, the present invention has the following beneficial effects:
[0030] 1. The present invention solves the problems that the existing spotlight antenna has poor adaptability when facing buildings of different heights, and that the installation position needs to be drilled by tools, resulting in low installation efficiency. The first adjustment component is rotated on the mounting plate to adjust the angle of the two broadband oscillators inside the spotlight, thereby controlling its radiation range, and the broadband oscillators are placed on a radius line from the center of the mounting base to the outer circle through the second adjustment component, and the distance between the two broadband oscillators and the center of the circle can be adjusted along the radius line, further adjusting their radiation direction and optimizing the standing wave ratio, thereby improving the performance and efficiency of the transmission system; this adjustment method enables workers to quickly make adaptive adjustments according to buildings of different sizes and heights, so that the radiation range is closer to the shape of the building, reducing signal leakage and pilot pollution, and improving installation and adjustment efficiency.
[0031] 2. By setting the shape of the reflection strip into a right-angled triangle with the inclined surface facing the broadband oscillator, it can reflect and beam the signal, making the signal more concentrated and the main lobe signal energy stronger, thereby avoiding signal leakage, and the tip of the reflection strip points to the mounting base, which can cooperate with the protrusion on the mounting base to indicate the rotation angle. In addition, the main material of the reflection strip is plastic, which makes it lower in cost. In addition, multiple reflection strips arranged at a certain angle also have the function of displaying the adjustment angle.
[0032] 3. Connect the conductive sheet to the feeder through the wire hole reserved inside the connecting column. When installing the broadband vibrator, you only need to clamp the broadband vibrator between the movable plate and the fixed plate to complete the connection. This avoids the traditional installation method of drilling holes and then fixing with bolts, reduces the time required for installation, and greatly improves work efficiency. At the same time, placing the connection between the feeder and the conductive sheet inside the connecting column can protect the end of the feeder during the adjustment of the broadband vibrator to prevent damage caused by excessive bending of the end.
[0033] 4. By processing the upper edges of through slot one and through slot two into upwardly inclined chamfers, they can also play the role of reflecting signals. At the same time, multiple embedded trapezoidal multi-faceted reflection structures are provided at the chamfers of the edges of through slot one and through slot two, so that the signal can be reflected multiple times after contacting it, thereby achieving the effect of enhancing signal strength, gaining signal transmission, and bundling and enhancing the main lobe signal energy.

The vertical section of the reflective strip 9 is a right triangle with the hypotenuse facing the top of the first adjustment component 7. The hypotenuse surface of the reflective strip 9 is made of aluminum, and the inclination angle of the inclination angle of the bevel is the same as the inclination angle of the hypotenuse of the mounting seat 701, so that it has the function of reflecting and beaming signals, making the signals more concentrated and the main lobe signal energy stronger, thereby avoiding signal leakage. At the same time, the main body parts of the reflective strip 9 except the bevel are made of plastic, which makes it lower in cost and can also avoid interference caused by other directions of the reflective strip 9 facing the signal. There are 36 reflective strips 9, including 5 long reflective strips 9 and 31 short reflective strips 9. A long reflective strip 9 is arranged after every 5 reflective strips 9. The angle between each reflective strip 9 is 6 degrees. Since each reflective strip 9 is arranged at a certain angle, workers can know the adjustment angle more clearly when adjusting the two broadband oscillators 5 in the spotlight, so that the adjustment error is smaller; a slide rail 12 is provided on the rear half of the lower surface of the mounting plate 6. The inner surface of the slide rail 12 is made of a smooth material with low friction, so that the adjustment of the first adjustment component 7 is smoother and the user experience is better. The slide rail 12 is an arc shape of 180 degrees as a whole, so that the broadband oscillators 5 can be adjusted more accurately. The frequency oscillator 5 can be adjusted 180 degrees in the spotlight to adjust its radiation angle. The vertical section of the slide rail 12 is L-shaped and openings are provided at both ends of the L-shape; the mounting plate 6 is located on the outer ring of the arc-shaped slide rail 12 and is provided with a locking groove 10 of the same shape as the arc-shaped slide rail 12.

Therefore, the surface of the locking groove 10 is processed and sprayed with a thermoplastic rubber coating. The thermoplastic rubber coating has good friction and can maintain its performance over a wide temperature range. Therefore, this material can maintain its due function for a long time, thereby ensuring the service life of the equipment.

The slide block 702 is L-shaped and arranged in the slide rail 12. The contact positions of the slide block 702 and the slide rail 12 are both arc-shaped structures. This shape can reduce the contact area between the slide block 702 and the slide rail 12, so that the resistance of the mounting seat 701 when rotating relative to the mounting plate 6 is smaller. The extension plate 703 is connected to the slide block 702. The bottom of the extension plate 703 is lower than the lower surface of the mounting plate 6.

Except for the extension plate 806 and the locking bolt 807, the above parts are provided with two groups and are all arranged symmetrically about the center point of the mounting base 701, so that when adjusting, the worker only needs to adjust the position of one of the broadband vibrators 5 to synchronously adjust the other one, avoiding the problem of deviation in the radiation range caused by different distance adjustment of the two broadband vibrators 5, thereby making the adjustment efficiency and accuracy of the broadband vibrator 5 higher; the extension plate 806 is connected to the front side of the connecting block 808 on one side, and the extension plate 806 is connected to the front side of the connecting block 808 on one side. 806 is made of soft rubber, the locking bolt 807 is connected to the extension plate 806 and is connected to the limit groove 813, the movable plate 802 is slidably connected to the fixed plate 801, the conductive sheet 803 is connected to the fixed plate 801, the connecting column 1 810 and the connecting column 2 811 are both connected to the lower side of the fixed plate 801, the connecting column 1 810 is a hollow tube, and the above-mentioned hollow tube can accommodate the feeder to pass through, the hollow part of the connecting column 1 810 is connected to the conductive sheet 803, during installation, it is only necessary to pass the feeder through the connection block 808 and the reserved hollow wire hole in the connecting column 1 810, and connect the feeder to the conductive sheet 803, without the need to specifically connect the feeder to the broadband vibrator 5, and at the same time, it has the function of gathering and arranging cables to prevent the feeder from being entangled together during the adjustment process of the broadband vibrator 5 and causing damage to the feeder.
[0048] The connecting block 808 is fixed on the lower side of the connecting column 1 810 and the connecting column 2 811. The connecting column 1 810 and the connecting column 2 811 are respectively slidably connected with the through groove 13 and the through groove 2 14. The sliding groove 812 and the limiting groove 813 are arranged on the connecting block 808. The limiting groove 813 is opened on one side of the sliding groove 812. The rack 804 is fixed on the side of the connecting block 808 away from the sliding groove 812. The limiting block 805 is connected to the rack 804. The limiting block 805 can limit the rack 804 in sliding. The position of the second adjustment component 8 in the groove 812 is prevented from being damaged by friction between the serrated side and the inner wall of the slide groove 812. The baffle 809 is connected to the rack 804. The baffle 809 can prevent the rack 804 from moving out of the slide groove 812.

The spring 816 is located in the mounting groove 814, and the two ends of the spring 816 are respectively connected to the slide bar 815 and the mounting groove 814, so that when installing the broadband vibrator 5, there is no need to install the wideband vibrator 5 as in the conventional method. Similar to the installation method that requires drilling, this solution only requires one end of the broadband vibrator 5 to rest against the movable plate 802 and push it away from the fixed plate 801. When the distance between the movable plate 802 and the fixed plate 801 is sufficient to place the broadband vibrator 5, it can be put down. At this time, the movable plate 802 clamps the broadband vibrator 5 under the action of the spring 816 to prevent it from falling, so that the device can achieve the installation and fixation of the broadband vibrator 5 more quickly, and can also facilitate the replacement of the broadband vibrator 5, greatly improving the work efficiency of the workers.
[0049] The specific working principle is as follows: when installing the spotlight antenna, first separate the cover plate 1 from the outer cover 2, then unscrew the screws on the mounting plate 6, and remove the mounting plate 6, then pass the feeder through the feeder interface 4 and pull it into the outer cover 2, then pass the feeder in the outer cover 2 through the hollow wire hole reserved inside the connecting column 810, and connect it to the conductive sheet 803, then clamp the two broadband vibrators 5 between the two sets of movable plates 802 and the fixed plate 801 respectively and make them contact and connect with the conductive sheet 803, then the staff calculates the signal radiation range that needs to be covered according to the height and width of the target building, and converts it into the distance and angle that the broadband vibrator 5 needs to be adjusted, then adjust the angle of the two broadband vibrators 5 relative to the outer cover 2 by rotating the mounting seat 701, thereby controlling its radiation range, and when the adjustment is completed, tighten the locking bolt 705 to make it engage with the locking groove 1 10 is cooperated to fix the mounting base 701, and then the spacing between the two broadband oscillators 5 is changed by moving the fixing plate 801 to further adjust its radiation direction. The standing wave ratio can also be optimized by adjusting the spacing between the two oscillators, thereby improving the performance and efficiency of the transmission system. After the adjustment is completed, the locking bolt 807 is tightened to make it cooperate with the limit block 805 to fix the relative position of the broadband oscillator 5. After the adjustment, the mounting plate 6 is fixed in the outer cover 2. This adjustment method allows workers to quickly adapt to buildings of different sizes and heights, so that its radiation range is closer to the shape of the building, reducing signal leakage and pilot pollution, and improving installation and adjustment efficiency. After the two broadband oscillators 5 are adjusted to the appropriate position, the cover plate 1 is fixed to the outer cover 2 again, and finally the entire spotlight antenna is installed in the appropriate position through the mounting bracket 3.
