Description

Technical Field

[0001] The present invention belongs to the field of mobile traffic technology, and in particular relates to a vibrator mounting seat, a radiation component equipped with the vibrator mounting seat, and an antenna equipped with the radiation component. Background Art

[0002] In the field of communications, the performance of antennas is directly related to the quality and efficiency of communication systems. Radiating elements, as key components of antennas, are usually installed on the reflector of the antenna to effectively radiate and receive electromagnetic wave signals.

[0003] However, the installation stability of the radiating vibrator is crucial to the communication performance of the antenna. It not only determines the radiation pattern and signal coverage of the antenna, but also directly affects the signal transmission efficiency and communication quality. If the radiating vibrator is installed unstably, it will cause a series of problems. First, unstable installation may cause the position of the radiating vibrator to shift, thereby changing the radiation direction of the antenna, causing the originally designed signal coverage to change, affecting the continuity and stability of communication. Second, unstable installation may also cause a loose connection between the radiating vibrator and the reflector, resulting in signal leakage or poor reflection, further reducing the communication performance of the antenna. In addition, unstable installation may also cause interference to the feeding network, resulting in signal distortion or reduced transmission efficiency.

[0004] Especially in antennas with more frequency bands, in order to effectively reduce the size of the antenna, high and low frequency oscillators are often arranged in a co-aperture layout. In this layout, the high frequency array is placed below the radiation surface of the low frequency array, which requires the low frequency array to have not only good radiation performance, but also excellent wave transmission performance to ensure that the high frequency array can work normally and perform at its best.

[0005] Among many low-frequency oscillators, PCB oscillators are highly favored due to their excellent wave transmission performance. However, there is a problem that cannot be ignored in practical applications of PCB oscillators, that is, their intermodulation stability is poor. During the transportation, installation or long-term operation of the antenna, the installation stability of the PCB oscillator is easily damaged due to external vibration or mechanical stress, resulting in unqualified intermodulation performance.

[0006] Once the intermodulation performance of the PCB vibrator has problems, it will not only directly affect its own radiation performance, but may also interfere with the high-frequency vibrator next to it, thus greatly affecting the radiation performance of the entire antenna. Specifically, unstable PCB vibrators may cause the radiation direction of the antenna to shift, the signal coverage range to change, the signal quality to degrade, and even cause communication interruption.

[0044] In an exemplary embodiment of the present invention, Figure 1The antenna 100 includes a radiation component, and the radiation component includes the vibrator mounting seat 200 and the radiation vibrator 300. The radiation vibrator 300 is installed in the vibrator mounting seat 200. The vibrator mounting seat 200 is used to fix the radiation vibrator 300 and maintain the installation stability of the radiation vibrator 300, so that the radiation vibrator 300 can work stably and maintain the stability of the radiation performance of the radiation vibrator 300.

[0045] Combination Figure 2 The radiation oscillator 300 includes a dielectric plate 310, a plurality of radiation arms 320 and a feeding component 330. The plurality of radiation arms 320 are arranged on one side of the dielectric plate 310. The plurality of radiation arms 320 and the dielectric plate 310 together constitute a radiation panel. The feeding component 330 is electrically connected to the plurality of radiation arms 320. The feeding component 330 is used to connect to an external component and receive an external current to feed the radiation arms 320. In this embodiment, it is recommended that the plurality of radiation arms 320 be printed on the dielectric plate 310, but this should not be construed as a limitation to the present invention.

[0046] In this embodiment, the radiating element 300 is a dual-polarization element, and the radiating element 300 includes four radiating arms 320, and the four radiating arms 320 are divided into two pairs, and the two pairs of radiating arms 320 respectively work in different polarizations. This is used as an example to describe the present invention, but it should not be understood as a limitation to the present invention.

[0047] The feeding component 330 includes a pair of feeding plates 331, and the pair of feeding plates 331 respectively feed the two pairs of radiating arms 320, and specifically each feeding plate 331 feeds the corresponding pair of radiating arms 320. Alternatively, the feeding component 330 also includes four baluns, and the four baluns respectively support the four radiating arms 320. In this embodiment, the feeding plates 331 are fixed to the radiating arms 320 by welding.

[0048] Combination Figure 3The vibrator mounting seat 200 includes an annular top seat 210, an annular base 220 and a plurality of support arms 230. The annular top seat 210 and the annular base 220 are arranged vertically up and down along the radiating vibrator 300. The annular top seat 210 is located above the annular base 220. The two ends of the support arm 230 are respectively connected to the annular top seat 210 and the annular base 220. The plurality of support arms 230 are respectively connected to the annular top seat 210 and the annular base 220 to maintain the structural stability of the vibrator mounting seat 200. In this embodiment, the plurality of support arms 230 are evenly arranged along the circumferential direction of the annular top seat 210, so that the plurality of support arms 230 can stably connect the annular top seat 210 and the annular base 220 to maintain the structural stability of the vibrator mounting seat 200.

[0049] The annular top seat 210 is an annular structure, and a top space 211 is provided inside the annular top seat 210; the annular base 220 is also an annular structure, and a bottom space 221 is provided inside the annular base 220; the annular top seat 210, the annular base 220 and the plurality of support arms 230 are surrounded to form an installation space 240. In this embodiment, the top space 211 is a through-hole structure, and the bottom space 221 is also a through-hole structure.

[0050] Combination Figure 3 and Figure 8 The annular top seat 210 includes a front side 212 and a back side 213, the front side 212 and the back side 213 face oppositely, and the back side 213 faces the annular base 220. When the radiation vibrator 300 is installed in the vibrator mounting seat 200, the radiation panel of the radiation vibrator 300 is arranged on the front side 212 of the annular top seat 210, and the feeding component 330 of the radiation vibrator 300 is installed in the mounting space 240.

[0051] In this embodiment, combined with Figure 3 The annular top seat 210 is also provided with a plurality of extension arms 214, which are arranged corresponding to the plurality of radiation arms 320 of the radiation oscillator 300, and the extension arms 214 are extended along the polarization axis of the corresponding radiation arms 320, so that the extension arms 214 are protruded relative to the annular top seat 210, so as to further support the radiation panel through the extension arms 214, so that the radiation panel can be stably arranged on the annular top seat 210. In this embodiment, since the radiation oscillator 300 is provided with four radiation arms 320, the annular top seat 210 is also provided with four extension arms 214 accordingly.

[0052] The annular top seat 210 is provided with a fixing structure (the fixing structure is referred to as a first fixing structure), and the radiation panel is fixed to the annular top seat 210 through the first fixing structure, so that the radiation oscillator 300 can stably maintain installation stability.

[0053] In one embodiment, in combination Figure 3 The first fixing structure includes a positioning pin (the positioning pin is referred to as a first positioning pin 251), and the first positioning pin 251 is protruded toward the radiation panel along the vertical direction. Figure 2 The dielectric plate 310 of the radiation oscillator 300 is provided with a positioning hole (the positioning hole is referred to as the first positioning hole 311), combined with Figure 7 The first positioning pin 251 is inserted into the corresponding first positioning hole 311 so that the annular top seat 210 and the radiation panel are positioned and limited to each other, so that the radiation panel can be stably installed on the annular top seat 210 to maintain the installation stability of the radiation vibrator 300.

[0054] In this embodiment, a plurality of first positioning pins 251 are provided on the first fixing structure, and the plurality of first positioning pins 251 are evenly distributed on the annular top seat 210 and the plurality of extension arms 214. A plurality of first positioning holes 311 are correspondingly opened on the dielectric plate 310, and the plurality of first positioning pins 251 are correspondingly inserted into the plurality of first positioning holes 311 to evenly fix the radiation panel, thereby further improving the installation stability of the radiation vibrator 300 and maintaining the radiation performance of the radiation vibrator 300 continuously stable.

[0055] In one embodiment, bolts are provided on the first fixing structure, screw holes are provided on the dielectric plate 310, and the bolts are threadedly connected to the screw holes so that the dielectric plate 310 is stably mounted on the annular top seat 210, thereby maintaining the installation stability of the radiation vibrator 300 and maintaining the stability of the radiation performance of the radiation vibrator 300.

[0056] In one embodiment, in combination Figure 3 The first fixing structure further includes an elastic stopper 252, and the elastic stopper 252 is protruded toward the radiation panel along the vertical direction. Figure 2 A fixing hole 312 is provided on the dielectric plate 310 of the radiation vibrator 300, and the elastic limiting member 252 is inserted into the fixing hole 312, and the elastic limiting member 252 is elastically engaged with the dielectric plate 310, so that the radiation panel can be stably set on the annular top seat 210 to maintain the installation stability of the radiation vibrator 300.

[0057] Specifically, combined Figure 4The elastic stopper 252 includes a support column 253 and a pair of spring pieces 254. The support column 253 is protruding toward the radiation panel along the vertical direction. The top 2541 of the spring piece 254 in the vertical direction is connected to the top 2531 of the support column 253 in the vertical direction. The spring piece 254 and the support column 253 are arranged at an angle, that is, the end 2542 of the spring piece 254 in the vertical direction is relatively far away from the support column 253. The pair of spring pieces 254 are arranged on both sides of the support column 253, and the pair of spring pieces 254 are symmetrical with respect to the support column 253.

[0058] Under the action of external force, the spring pieces 254 can be relatively far away from or close to the support column 253. When the pair of spring pieces 254 are away from the support column 253 at the same time, the pair of spring pieces 254 are in an open state; when the pair of spring pieces 254 are close to the support column 253 at the same time, the pair of spring pieces 254 are in a contracted state. In this embodiment, the pair of spring pieces 254 are always in an open state.

[0059] Combination Figure 2 , Figure 4 and Figure 7 , when the pair of spring pieces 254 are in the open state, the distance between the respective ends 2542 of the pair of spring pieces 254 of the elastic limiting member 252 is greater than the aperture of the fixing hole 312. Since the top end 2541 of the spring piece 254 is connected to the top end 2531 of the support column 253, when the elastic limiting member 252 is inserted into the fixing hole 312 from bottom to top along the vertical direction, the pair of relatively open spring pieces 254 gradually shrink under the restriction of the fixing hole 312 until the ends 2542 of the spring pieces 254 pass through the fixing hole 312. After the ends 2542 of the spring pieces 254 pass through the fixing hole 312, the pair of spring pieces 254 in the shrinking state recover to the open state.

[0060] Because the distance between the ends 2542 of the pair of spring clips 254 in the open state is greater than the aperture of the fixing hole 312, the pair of spring clips 254 can no longer pass through the fixing hole 312. The radiation panel is limited by the pair of spring clips 254 to maintain the installation stability of the radiation vibrator 300, thereby maintaining the stability of the radiation performance of the radiation vibrator 300.

[0061] In a further embodiment, in combination Figure 4 and Figure 7, a notch (called a limiting notch 2543) is provided at or near the end 2542 of the spring sheet 254, and the limiting notch 2543 is engaged with the edge of the fixing hole 312. The limiting notches 2543 of the pair of spring sheets 254 are oriented in opposite directions, and the limiting notches 2543 of the pair of spring sheets 254 are engaged with the edge of the fixing hole 312, respectively. Moreover, because the pair of spring sheets 254 are disposed on both sides of the support column 253, the radiation panel can be further stably disposed on the annular top seat 210 under the limiting of the limiting notches 2543 of the pair of spring sheets 254, so as to further improve the installation stability of the radiation vibrator 300 and further maintain the stability of the radiation performance of the radiation vibrator 300.

[0062] In one embodiment, in combination Figure 2 The radiation vibrator 300 further includes a bottom plate 340, and the bottom end of the feeding component 330 is inserted into the bottom plate 340 to fix the feeding component 330. In this embodiment, the feeding component 330 includes a pair of feeding plates 331, and the bottom plate 340 is a grounding plate as an example to describe the present invention, but it should not be understood as a limitation of the present invention. The pair of feeding plates 331 are inserted into the grounding plate to enable the radiation vibrator 300 to be grounded.

[0063] Combination Figure 3 , Figure 5 and Figure 8 The annular base 220 is provided with the bottom space 221, and the bottom plate 340 is installed in the bottom space 221. In the present embodiment, the shape and size of the bottom plate 340 are the same as the shape and size of the bottom space 221, so that the bottom space 221 can limit the bottom plate 340, so that the bottom plate 340 is stably arranged in the bottom space 221, thereby improving the installation stability of the radiation vibrator 300.

[0064] In this embodiment, the annular base 220 includes a top surface 222 and a bottom surface 223 facing oppositely, and the top surface 222 of the annular base 220 is arranged opposite to the reverse surface 213 of the annular top seat 210. A plurality of limiting pieces 224 are arranged on the bottom surface 223 of the annular base 220, and the limiting pieces 224 are arranged on the edge of the bottom space 221, and the limiting pieces 224 are extended toward the inside of the bottom space 221.

[0065] When the bottom plate 340 is installed in the bottom space 221, the bottom plate 340 is also seated on the multiple limiting plates 224, and the multiple limiting plates 224 cooperate to limit the bottom plate 340 from escaping from the bottom of the bottom space 221, thereby maintaining the installation stability of the radiation vibrator 300, and further maintaining the stability of the radiation performance of the radiation vibrator 300.

Fig. 9 The reflector 400 is provided with a positioning hole (the positioning hole is referred to as the second positioning hole 410). Fig.10 The second positioning pin 261 is inserted into the corresponding second positioning hole 410 so that the annular top seat 210 and the reflecting plate 400 are positioned and limited to each other, so that the annular base 220 can be stably installed on the reflecting plate 400, so that the radiation vibrator 300 can be stably installed through the vibrator mounting seat 200, thereby improving the stability of the radiation performance of the radiation vibrator 300.

[0069] In this embodiment, a plurality of second positioning pins 261 are provided on the second fixing structure, and the plurality of second positioning pins 261 are evenly distributed on the annular base 220. A plurality of second positioning holes 410 are correspondingly opened on the reflecting plate 400, and the plurality of second positioning pins 261 are correspondingly inserted into the plurality of second positioning holes 410 to evenly fix the annular base 220, thereby further improving the installation stability of the vibrator mounting seat 200 and the radiating vibrator 300, so that the radiation performance of the radiating vibrator 300 is continuously maintained stable.

[0071] In one embodiment, in combination Fig. 9 and Fig.10 The reflecting plate 400 is provided with a receiving hole 420, and the annular base 220 is installed in the receiving hole 420. The shape and size of the cross section of the annular base 220 are the same or substantially the same as the shape and size of the receiving hole 420, so that the annular base 220 can be stably installed in the receiving hole 420.

[0072] The second fixing structure also includes an elastic limiting piece 262, combined with Figure 5 and Figure 6 , the elastic limiting piece 262 is arranged on the outer side of the annular base 220. The elastic limiting piece 262 includes a first elastic section 2621 and a second elastic section 2622, one end of the first elastic section 2621 is connected to the annular base 220, and the first elastic section 2621 is protruded relative to the bottom surface 223 of the annular base 220 in a direction away from the annular top seat 210.
