Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and in particular to a mechanical switch and a wide and narrow beam switchable antenna using the mechanical switch. Background Art

[0002] Base station antennas are essential equipment for wireless communication, playing the role of energy conversion, that is, converting the high-frequency current energy in the feeder into electromagnetic waves in free space for transmission (transmitting antenna) or vice versa (receiving antenna).

[0003] In the actual application process, according to different actual situations such as network coverage requirements, traffic distribution, anti-interference requirements, and network service quality, the selection of antennas will also change. The selection of antenna types is closely related to terrain, ground objects, and traffic distribution. Therefore, under certain special requirements, such as in places like stations and airports where the flow of people changes frequently, base station antennas with a fixed beam width cannot adaptively complete network optimization coverage, and the cost of manually replacing antennas with different beam widths is extremely high. Thus, an integrated base station antenna with switchable wide and narrow beam widths is urgently needed, and a switch that can switch the working state of the antenna between a narrow beam and a wide beam will bring great convenience. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the technology and provide a mechanical switch and a wide and narrow beam switchable antenna using the mechanical switch, which can realize the arbitrary switching of the working state of the antenna between a narrow beam and a wide beam.

[0005] The first aspect of the present invention provides a mechanical switch, including a PCB circuit board. A first circuit and a second circuit are provided on the first surface of the PCB circuit board. The first circuit includes a first branch and a second branch arranged at intervals along the longitudinal direction of the PCB circuit board. A PCB pointer slider is installed at the position of the second circuit on the PCB circuit board.

[0010] Further, the first branch and the second branch have the same structure. The inner ends of the first branch and the second branch are adjacent and both are bent towards the vertical branch of the second circuit.

[0011] Further, the PCB pointer slider can rotate from the inner end of the first branch to the inner end of the second branch or from the inner end of the second branch to the inner end of the first branch; when the PCB pointer slider rotates to the inner end of the first branch, the end of the second end of the coupling circuit overlaps with the end of the inner end of the first branch, and the second end of the coupling circuit is coupled to the inner end of the first branch. When the PCB pointer slider rotates to the inner end of the second branch, the end of the second end of the coupling circuit overlaps with the end of the inner end of the second branch, and the second end of the coupling circuit is coupled to the inner end of the second branch.

[0012] Further, when the PCB pointer slider rotates to the inner end of the first branch or the inner end of the second branch, the mechanical switch is in the working mode. When the PCB pointer slider rotates between the first branch and the second branch, the mechanical switch is in the non-working mode.

[0013] The second aspect of the present invention provides a wide and narrow beam switchable antenna, which includes a reflector, two mechanical switches mounted on the front side of the reflector, and a phase shifter component mounted on the back side of the reflector.

When the PCB pointer slider rotates to the first branch, the second end of the coupling circuit is coupled to the first branch, so that the first branch is connected to the second circuit. When the PCB pointer slider rotates to the second branch, the second end of the coupling circuit is coupled to the second branch, so that the second branch is connected to the second circuit.

[0014] Further, it also includes N first radiation units and M second radiation units mounted on the front side of the reflector.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Refer to Figure 1, a mechanical switch 100 provided by the present invention includes a rectangular PCB circuit board 10. On the longitudinal two sides of the front side (the first side) of the PCB circuit board 10, a first circuit 11 and a second circuit 12 are respectively provided. The first circuit 11 includes a first branch 111 and a second branch 112 arranged at intervals along the longitudinal direction of the PCB circuit board 10. On the back side (the second side) of the PCB circuit board 10, a ground layer (not shown in the figure) is provided for grounding. At the position of the second circuit 12 on the PCB circuit board 10, a strip-shaped PCB pointer slider 14 is installed. The PCB pointer slider 14 can rotate from the first branch 111 to the second branch 112 or from the second branch 112 to the first branch 111 with the second circuit 12 as a fulcrum. On the side of the PCB pointer slider 14 close to the PCB circuit board 10, a coupling circuit 15 is provided. The first end 15a of the coupling circuit 15 is coupled to the second circuit 12. When the PCB pointer slider 14 rotates to the first branch 111, the second end 15b of the coupling circuit 15 is coupled to the first branch 111, so that the first branch 111 is communicated with the second circuit 12, and the narrow beam working state of the antenna can be realized when the mechanical switch 100 is actually applied to the antenna. When the PCB pointer slider 14 rotates to the second branch 112, the second end 15b of the coupling circuit 15 is coupled to the second branch 112, so that the second branch 112 is communicated with the second circuit 12, and the wide beam working state of the antenna can be realized when the mechanical switch 100 is actually applied to the antenna. Through the mechanical switch of the present invention, the working state of the antenna can be arbitrarily switched between a narrow beam and a wide beam. In this specification, the first side of the PCB circuit board 10 provided with the first circuit 11 and the second circuit 12 is defined as the front side, and the second side provided with the ground layer is defined as the back side.

[0026] The structure and principle of the present invention will be described in detail below.

[0027] Please refer to Figure 1 and Figure 2 , in this embodiment, specifically, the structures of the first branch 111 and the second branch 112 are the same. The inner end 111a of the first branch 111 is adjacent to the inner end 112a of the second branch 112. The outer end 111b of the first branch 111 and the outer end 112b of the second branch 112 are respectively used for connecting with a coaxial cable (such as Figure 1connected to the label 20) therein. The second circuit 12 is in an L shape and includes a horizontal branch 121 extending longitudinally along the PCB circuit board 10 and a vertical branch 122 connected to the first end of the horizontal branch 121. The vertical branch 122 is close to the first circuit 11, and the axis of the vertical branch 122 is located between the first branch 111 and the second branch 112. The second end 121b of the horizontal branch 121 is used to connect to a coaxial cable. Notches 101 are respectively provided at the positions of the outer ends 111b of the corresponding first branch 111, the outer ends 112b of the second branch 112, and the second end 121b of the horizontal branch 121 on the PCB circuit board 10. The notches 101 are used to accommodate the ends of the corresponding coaxial cables, facilitating the installation of the coaxial cables. During actual installation of the coaxial cable, the outer conductor of the coaxial cable is welded to the ground layer of the PCB circuit board 10, and the inner conductor of the coaxial cable is welded to the end of the corresponding circuit. The inner ends 111a of the first branch 111 and the inner ends 112a of the second branch 112 are respectively bent towards the vertical branch 122 of the second circuit 12.

[0028] A connector 13 is installed at the position of the first end 122a of the vertical branch 122 of the second circuit 12. The PCB pointer slider 14 is installed on the connector 13. The PCB pointer slider 14 can rotate around the connector 13, so as to realize rotation from the first branch 111 to the second branch 112 or from the second branch 112 to the first branch 111. The connector 13 is preferably an R-shaped plastic rivet.

[0029] The PCB pointer slider 14 has a connection end 14a and a rotation end 14b. The connection end 14a is installed on the connector 13. The PCB circuit board 10, the first end 122a of the vertical branch 122 of the second circuit 12, the connection end 14a of the PCB pointer slider 14, and the first end 15a of the coupling circuit 15 have through holes for installing the connector 13. The rotation end 14b extends outside the side of the PCB circuit board 10 close to the first circuit 11 and a pull rod 16 is installed through a mounting member 141. The pull rod 16 is parallel to the PCB circuit board 10. The pull rod 16 can move along the longitudinal direction of the PCB circuit board 10 under the action of an external force, that is, by pulling the pull rod 16, the PCB pointer slider 14 can be rotated around the connector 13 from the first branch 111 to the second branch 112 or from the second branch 112 to the first branch 111.

[0030] In this embodiment, the PCB pointer slider 14 can rotate from the inner end 111a of the first branch 111 to the inner end 112a of the second branch 112 or from the inner end 112a of the second branch 112 to the inner end 11a of the first branch 111.

[0031] The end of the first end of the coupling line 15 overlaps with the end of the first end of the vertical branch 122 of the second line 12, and the first end 15a of the coupling line 15 is coupled to the first end 122a of the vertical branch 122, so as to realize the coupling connection between the first end 15a of the coupling line 15 and the second line 12. Combined with Figure 3 As shown, when the PCB pointer slider 14 is driven by the pull rod 16 to rotate around the connecting member 13 to the inner end 111a of the first branch 111, the end of the second end of the coupling line 15 overlaps with the end of the inner end of the first branch 111, and the second end 15b of the coupling line 15 is coupled to the inner end 111a of the first branch 111, so as to realize the coupling connection between the second end 15b of the coupling line 15 and the first branch 111, thereby realizing the connection between the first branch 111 and the second line 12. When the PCB pointer slider 14 rotates to the inner end 112a of the second branch 112, the end of the second end of the coupling line 15 overlaps with the end of the inner end of the second branch 112, and the second end 15b of the coupling line 15 is coupled to the inner end 112a of the second branch 112, so as to realize the coupling connection between the second end 15b of the coupling line 15 and the second branch 112, thereby realizing the connection between the second branch 112 and the second line 12. Preferably, the end of the first end of the coupling line 15 and the end of the first end of the vertical branch 122 are both circular, and the end of the second end of the coupling line 15 and the end of the inner end of the first branch 111 and the end of the inner end of the second branch 112 are all rectangular.

[0032] When the PCB pointer slider 14 rotates to the inner end 111a of the first branch 111 or the inner end 112a of the second branch 112, the mechanical switch 100 is in the working mode. The position when the PCB pointer slider 14 rotates to the inner end 111a of the first branch 111 can be defined as the "0" position, and the position when the PCB pointer slider 14 rotates to the inner end 112a of the second branch 112 can be defined as the "1" position. When the PCB pointer slider 14 is at the "0" position, the first branch 111 is connected to the second line 12, that is, the first branch 111 works and the second branch 12 does not work. When the PCB pointer slider 14 is at the "1" position, the second branch 112 is connected to the second line 12, that is, the second branch 112 works and the first branch 111 does not work. When the PCB pointer slider 14 rotates between the first branch 111 and the second branch 112, the mechanical switch 100 is in the non-working mode, that is, both the first branch 111 and the second branch 112 do not work.

[0033] Reference Figures 4 to 6, is a schematic structural diagram of the wide and narrow beam switchable antenna 300 of the mechanical switch 100 applying the present invention. The wide and narrow beam switchable antenna 300 includes a reflector 301, two mechanical switches 100 mounted on the front of the reflector 301, a phase shifter component 200 mounted on the back of the reflector 301, N first radiation units 302 mounted on the front of the reflector 301, and M second radiation units 303 mounted on the front of the reflector 301. The two mechanical switches 100 are symmetric about the longitudinal axis of the front of the reflector 301. The phase shifter component 200 is located between the two mechanical switches 100 and is respectively connected to the two mechanical switches 100. The M second radiation units 303 and the N first radiation units 302 are arranged at intervals in sequence along the longitudinal direction of the reflector 301, and the two mechanical switches 100 are located between adjacent second radiation units 303 and first radiation units 302. In this embodiment, the front of the reflector 301 has two mounting cavities, and the two mechanical switches 100 are respectively mounted in the corresponding mounting cavities. Both N and M are positive integers greater than or equal to 1.

[0034] Combined with Figure 7 As shown, the phase shifter component 200 has an input port 205, a first output port 201, and multiple second output ports 202. The first branch 111 and the second line 12 of one of the mechanical switches 100 are respectively connected to the first output port 201 of the phase shifter component 200 and the M second radiation units 303. The first branch 111 and the second line 12 of the other mechanical switch 100 are respectively connected to the input port 205 of the phase shifter component 200 and the radio frequency output port 304 mounted on one side of the reflector 301. The second branches 112 of the two mechanical switches 100 are connected to each other. The N first radiation units 302 are respectively connected to the multiple second output ports 202 of the phase shifter component 200.

[0035] In this embodiment, the number of the first radiation units 302 is five (i.e., N = 5), the number of the second radiation units 303 is one (i.e., M = 1), and one second radiation unit 303 and the five first radiation units 302 are arranged at intervals in sequence along the longitudinal direction of the reflector 301. The structures of the first radiation unit 302 and the second radiation unit 303 are the same. The number of the second output ports 202 of the phase shifter component 200 is five.

[0036] Specifically, please combine with Figure 7 As shown, for the convenience of description, the present invention defines Figure 7 the mechanical switch 100 on the left as the first mechanical switch, Figure 7The mechanical switch 100 on the right side is defined as the second mechanical switch. One input port 205, one first output port 201, and five second output ports 202 of the phase shifter component 200 are distributed on both sides of the phase shifter component 200. The input port 205 is close to the second mechanical switch, and the first output port 201 is close to the first mechanical switch. The outer end 111b of the first branch 111 of the first mechanical switch is connected to the first output port 201 of the phase shifter component 200 through the first coaxial cable 203. The outer end 111b of the first branch 111 of the second mechanical switch is connected to the input port 205 of the phase shifter component 200 through the second coaxial cable 204. The outer ends 112b of the second branches 112 of the first mechanical switch and the second mechanical switch are connected through a third coaxial cable (not shown in the figure). The second end of the second line 12 of the first mechanical switch (i.e., the second end 121b of the horizontal branch 121) is connected to the second radiation unit 303 through a fourth coaxial cable (not shown in the figure). The second end of the second line 12 of the second mechanical switch (i.e., the second end 121b of the horizontal branch 121) is connected to the RF output port 304 through a fifth coaxial cable (not shown in the figure). The five first radiation units 302 are respectively connected to the five second output ports 202 of the phase shifter component 200 through sixth coaxial cables (not shown in the figure).

[0037] In other embodiments, the phase shifter component has one input port 205, one first output port 201, and four second output ports 202. Among the five first radiation units 302, two of the first radiation units 302 are connected in parallel and then connected to one of the second output ports 202 through a sixth coaxial cable, and the remaining three first radiation units 302 are respectively connected to the remaining three second output ports 202.

[0038] Figure 8 This is the electrical schematic diagram of the wide and narrow beam switchable antenna 300 of the present invention. In combination with Figure 8As shown in the figure, the position when the PCB pointer slider 14 rotates to the inner end 111a of the first branch 111 is defined as the "0" position, and the position when the PCB pointer slider 14 rotates to the inner end 112a of the second branch 112 is defined as the "1" position. When the PCB pointer sliders 14 of the first mechanical switch and the second mechanical switch are both at the "0" position, the first mechanical switch and the second mechanical switch are connected to the phase shifter component 200, and all five first radiation units 302 and one second radiation unit 303 are excited. At this time, the wide and narrow beam switchable antenna 300 is in the narrow beam working state, which is suitable for application environments where wireless signals need to be transmitted over long distances. The electrical tilt of the wide and narrow beam switchable antenna 300 can be adjusted through the phase shifter component 200, that is, the wide and narrow beam switchable antenna 300 at this time is also an electrically adjustable antenna. When the PCB pointer sliders 14 of the first mechanical switch and the second mechanical switch are both at the "1" position, the first mechanical switch and the second mechanical switch are not connected to the phase shifter component 200, and the first mechanical switch is directly connected to the second mechanical switch. One second radiation unit 303 is excited, and the five first radiation units 302 are not excited. At this time, the wide and narrow beam switchable antenna 300 is in the wide beam working state, which is suitable for application environments where wireless signals need to cover a large area, that is, the wide and narrow beam switchable antenna 300 at this time is also a fixed tilt antenna.

[0039] In summary, through the action of the mechanical switch 100, the wide and narrow beam switchable antenna 300 can be freely switched between the narrow beam working state and the wide beam working state, and can be output through the same radio frequency output port 304, which simplifies the installation process of the wide and narrow beam switchable antenna 300, reduces the assembly difficulty, improves the production efficiency, and reduces the cost of the wide and narrow beam switchable antenna 300.

[0040] The above embodiments only represent the preferred implementation modes of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, such as combining different features in each embodiment, etc., and these all belong to the protection scope of the present invention.
