[0056] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0057] The present application provides an antenna device, by setting two antenna assemblies, the coverage range of the transmitted signal of the antenna device can be effectively increased, and the antenna device is more suitable for unmanned aerial vehicle countermeasures in a controlled area.

[0058] The present application also provides another aircraft countermeasure equipment comprising the above-mentioned antenna device.

[0059] Reference Figure 1 The present embodiment provides an antenna device, which comprises a mounting assembly 30 and two antenna assemblies 01 for transmitting signals. The antenna assemblies 01 are mounted on the mounting assembly 30. One of the two antenna assemblies 01 is inclined to a first direction with respect to a reference plane, and the other of the two antenna assemblies 01 is inclined to a second direction with respect to the reference plane, and the first direction is different from the second direction.

[0060] Specifically, the antenna device provided by the present embodiment can be applied to an aircraft countermeasure equipment, and the antenna device can transmit interference signals or receive radio signals. The mounting assembly 30 is a support for mounting the antenna assemblies 01, and the mounting assembly 30 can also fix the antenna assemblies 01 at a suitable angle, so that the antenna device can be applied to a corresponding application scenario, such as a controlled area. Figure 3 , the direction indicated by the arrow E is the first direction, and the direction indicated by the arrow F is the second direction, Figure 3 , L is the reference plane. In Figure 3For example, the first direction represents a tilt to the upper left, and the second direction represents a tilt to the upper right, i.e., the two antenna assemblies 01 are tilted to the upper left and upper right, respectively, so as to extend the coverage range of the signal along the horizontal direction (perpendicular to the reference plane). If the antenna assemblies 01 are arranged along the direction of gravity, it is considered that the antenna assemblies 01 are not tilted relative to the reference plane. The left antenna assembly 01 is tilted to the upper left, and it is considered that the antenna assembly 01 is rotated by a certain angle counterclockwise relative to the reference plane. The right antenna assembly 01 is tilted to the upper right, and it is considered that the antenna assembly 01 is rotated by a certain angle clockwise relative to the reference plane.

[0061] In this embodiment, the two antenna assemblies 01 are tilted to the two sides of the reference plane, respectively, so as to increase the coverage range of the signal. If the antenna device is applied to a controlled area, and Figure 3 the horizontal direction is parallel to the boundary of the controlled area, each antenna device can cover a wider range of the boundary of the controlled area, so as to be more convenient to apply to the scenario. It should be noted that the tilt directions of the two antenna assemblies 01 are different in this embodiment, but the specific placement modes of the two antenna assemblies 01 relative to the reference plane are not limited, for example: Figure 3 the two antenna assemblies 01 are located on the two sides of the reference plane, i.e., the two antenna assemblies 01 are tilted to the two sides of the reference plane, respectively, as shown in the view angle. Figure 3 The two antenna assemblies 01 do not overlap, and if the two antenna assemblies 01 are symmetrical relative to the reference plane, the projections of the two antenna assemblies 01 on the reference plane are coincident. Alternatively, the two antenna assemblies 01 can not be completely located on the two sides of the reference plane (not shown in the figure), but one is located in front and the other is located in back (i.e., the two antenna assemblies 01 have partial overlap as shown in the view angle). Figure 3 The two antenna assemblies 01 are still tilted to two different directions relative to the reference plane, and the projections of the two antenna assemblies 01 on the reference plane are located at two different positions in front and back of the reference plane.

[0062] It should be noted that the tilt angles of the two antenna assemblies 01 relative to the reference plane can be the same (as shown in the view angle). Figure 3 Alternatively, the tilt angles of the two antenna assemblies 01 relative to the reference plane can be different (not shown in the figure, for example, the tilt angle of the left antenna assembly 01 relative to the reference plane is greater than the tilt angle of the right antenna assembly 01 relative to the reference plane, i.e., the left antenna assembly 01 is rotated by a larger angle counterclockwise from the reference plane than the right antenna assembly 01 is rotated clockwise from the reference plane). Figure 3 For example, the left antenna assembly 01 is rotated by a larger angle counterclockwise from the reference plane than the right antenna assembly 01 is rotated clockwise from the reference plane).

[0063] Furthermore, by reasonably setting parameters such as gain and beamwidth of antenna assembly 01, the antenna device provided in this specific embodiment allows the projections of signals emitted by one of the two antenna assemblies 01 onto the second plane to overlap but not completely coincide with the projections of signals emitted by the other of the two antenna assemblies 01 onto the second plane. In other words, the signal coverage areas of the two antenna assemblies 01 partially intersect. Alternatively, one side of the boundary of the projections of the signals emitted by the two antenna assemblies 01 onto the second plane may touch each other. In other words, the signal coverage areas of the two antenna assemblies 01 may just meet. The second plane mentioned in this specific embodiment is parallel to... Figure 3 The horizontal direction is shown, and the second plane is perpendicular to the reference plane.

[0064] In practice, the second direction can be the opposite of the first direction, with the angle between the two directions being less than 180°. Alternatively, the first and second directions can simply be two directions with different orientations, depending on the specific circumstances.

[0065] Therefore, in this specific embodiment, by setting two antenna components 01 with different orientations relative to the reference plane, both sides of the reference plane are effectively covered, thus increasing the coverage range of the antenna device. If this antenna device is applied to a controlled area, due to its wider signal coverage, it helps to reduce the number of antenna devices and lower costs for the same area of ​​controlled space.

[0066] Furthermore, the two antenna assemblies 01 are symmetrically arranged about the reference plane. For example... Figure 3 As shown, one antenna assembly 01 is tilted in a first direction relative to the reference plane, and the other of the two antenna assemblies 01 is tilted in a second direction relative to the reference plane. The tilting directions of the two antenna assemblies 01 are opposite, and the tilt angles of the two antenna assemblies 01 relative to the reference plane are the same. The coverage area of ​​the signals emitted by the two antenna assemblies 01 is symmetrical about the reference plane. In actual use, the installation angle of the antenna assembly 01 can be adjusted with reference to the reference plane. In this embodiment, the two antenna assemblies 01 are symmetrically arranged about the reference plane, which can ensure that the signal coverage area on both sides of the reference plane is the same, thus making it easier to form a signal wall-like effect and facilitating applications in controlled areas.

[0067] Based on the above embodiments, such as Figures 7 to 10 As shown, the first coverage angle A of the signal projected onto the first plane by the antenna assembly 01 is smaller than the second coverage angle B of its projection onto the second plane. The first plane is perpendicular to the width direction D2 of the antenna assembly 01, and the second plane is perpendicular to the length direction D1 of the antenna assembly 01. Both the first and second directions are located on or parallel to the second plane.

[0068] This embodiment optimizes the signal radiation range of antenna assembly 01 itself. It should be noted that... Figures 7-10 The antenna assembly 01 is placed horizontally for ease of demonstration of its signal radiation range. This does not represent the actual installation angle of the antenna assembly 01 during application. The actual installation angle of the antenna assembly 01 can be determined by [the specific angle is missing in the original text]. Figure 3 For example.

[0069] In this specific embodiment, the first plane and the second plane can be planes perpendicular to the upper end surface 1a or the lower end surface 1b of the antenna assembly 01. For example, the first plane can be perpendicular to the antenna assembly 01 as follows: Figure 7 The sides shown are parallel, or the first plane is the antenna assembly 01, as shown. Figure 7 The plane shown represents the side surface. The second plane can be connected to antenna assembly 01 as shown... Figure 9 The sides shown are parallel, or the second plane is antenna assembly 01, as shown. Figure 9 The plane containing the side shown. Alternatively, the first plane and the second plane can also be planes with an angle greater than 0° and less than 90° between them and the upper end face 1a or the lower end face 1b of the antenna assembly 01. Here, the first plane and the second plane are merely reference planes, their purpose being to express the specific beamwidth of the interference signal from different perspectives. Figure 7 shows the projection of the interference signal onto the first plane with a relatively narrow first coverage angle A, which can also be seen as from... Figure 7 From the perspective shown, the beamwidth of the interference signal is relatively narrow. Figure 9 The projection of the interference signal onto the second plane shows a wide second coverage angle B, which can also be seen as from... Figure 9 From the perspective shown, the beamwidth of the interference signal is relatively wide. Therefore, in actual use, unlike clustered interference signals, the interference signal in this embodiment diffuses in a flat manner, and compared to the first plane, the interference signal in the second plane has a wider beamwidth, which can act as a "signal wall" to prevent aircraft intrusion.

[0070] In actual use, the antenna device of the embodiment is generally needed to emit interference signals to interfere with the UAVs entering the control area. Since the interference signals have the characteristic that the first coverage angle A projected on the first plane is smaller than the second coverage angle B projected on the second plane, the interference signals as a whole present a “signal wall” form. In this way, by arranging the antenna device of the embodiment around the control area, the interference signals can act as a signal wall that the UAVs cannot fly over on the boundary of the control area when the antenna device is used. Therefore, the antenna device of the embodiment can prevent the aircraft from entering the control area, and at the same time, due to the optimization of the radiation range as above, it can avoid emitting strong interference signals in all directions, thereby achieving the effect of reducing the influence on the nearby wireless communication.

[0071] In addition, if the antenna assembly 01 is applied to Figure 3 In the embodiment shown, for the left antenna assembly 01, the second coverage angle is B1, and for the right antenna assembly 01, the second coverage angle is B2. Therefore, in the antenna device, the signal coverage range of each antenna assembly 01 in the horizontal direction is wide, and since the two antenna assemblies 01 are respectively inclined to two different directions relative to the reference plane, this arrangement can further increase the signal coverage range in the horizontal direction, which is equivalent to further extending the length of the “signal wall”. Figure 3 , Figure 7 , Figure 9 As shown in the embodiment, the antenna assembly 01 includes an upper end face 1a from which the signals are emitted. The edge of the upper end face 1a in the length direction is parallel to the length direction D1 of the antenna assembly 01. The edge of the upper end face 1a in the width direction is parallel to the width direction D2 of the antenna assembly 01. The first plane is perpendicular to the second plane, and both the first plane and the second plane are perpendicular to the upper end face 1a.

[0072] In the embodiment, the first plane is parallel to the length direction D1 of the antenna assembly 01, the second plane is parallel to the width direction D2 of the antenna assembly 01, and the size of the width direction D2 of the antenna assembly 01 is smaller than the size of the length direction D1 of the antenna assembly 01. Since the radiation range of each antenna assembly 01 in the respective width direction D2 is wide, when the antenna device is arranged, the length direction edge of each antenna assembly 01 can be arranged perpendicular to the boundary of the control area, so that the radiation range of the entire antenna device along the boundary of the control area is wide, and the radiation range perpendicular to the boundary of the control area is narrow. Since the radiation range of the interference signals along the boundary of the control area is wide, the adjacent antenna devices can be arranged with a certain interval, as long as the interference signals radiated by the two antenna devices form a continuous coverage range. At the same time, the adjacent antenna devices have an interval, which can also avoid interference between the adjacent antenna devices when they are arranged and installed.

[0073] In a specific embodiment, as shown in Figure 2 Figure 1, the antenna assembly 01 comprises a mounting frame 16, a reflecting plate 14 and an antenna 15, wherein the mounting frame 16 is located on the reflecting plate 14. The antenna 15 is arranged on the mounting frame 16, and there is a gap between the antenna 15 and the reflecting plate 14.

[0074] Specifically, the antenna device can comprise two antenna assemblies 01, one of which is a first antenna assembly 10 and the other of which is a second antenna assembly 20. As shown in Figure 2 Figure 1, the first antenna assembly 10 comprises a main housing 12, the two ends of the length direction of the main housing 12 are respectively provided with a top cover 11 and a lower end cover 13, and the antenna 15, the reflecting plate 14 and the mounting frame 16 are located in the space enclosed by the main housing 12, the top cover 11 and the lower end cover 13. The antenna 15 is arranged on the reflecting plate 14, the reflecting plate 14 is provided with the mounting frame 16 for fixing the antenna 15, and there is a gap between the antenna 15 and the reflecting plate 14. The antenna 15 is an omnidirectional antenna, and the antenna 15 is located between the upper end face 1a and the reflecting plate 14. The specific structure of the second antenna assembly 20 can be the same as that of the first antenna assembly 10.

[0075] In actual use, the reflecting plate 14 can be made of metal, and the antenna 15 can be selected as a directional antenna or an omnidirectional antenna. If the antenna 15 is an omnidirectional antenna, the front lobe of the antenna 15 emits towards the upper end face 1a, and the reflecting plate 14 can reflect the back lobe of the antenna 15 to superimpose with the front lobe, so that the signal finally emitted from the upper end face 1a includes both the front lobe and the reflected back lobe of the antenna 15. For example, when the antenna 15 is selected as a glass steel antenna, the reflecting plate 14 can not only cooperate with the glass steel antenna to realize the effect of a directional antenna, but also be beneficial to improving the gain of the front lobe of the antenna 15.

[0076] In the specific embodiment, the antenna 15 is arranged on the mounting frame 16, which can effectively support and fix the antenna 15, and can effectively improve the stability of the installation of the antenna 15. Moreover, the antenna 15 is an omnidirectional antenna, the design of which is relatively simple, the installation process is more convenient, and it does not need to be accurately aligned and has a lower cost.

[0077] In a specific embodiment, as shown in Figure 1 , Figure 3 , Figure 4As shown, the mounting assembly 30 includes a support member 34 and a first rotating connector 33. One end of the support member 34 is connected to the fixing device 40. The first end of the first rotating connector 33 is mounted to the other end of the support member 34, and the second and third ends of the first rotating connector 33 are connected one-to-one to two antenna assemblies 01. Specifically, the second end of the first rotating connector 33 can be used to mount the first antenna assembly 10, and the third end of the first rotating connector 33 can be used to mount the second antenna assembly 20. The first rotating connector 33 and the support member 34 can have different mounting angles, so that the first rotating connector 33 can have different orientations in the first elevation plane, which is parallel to the reference plane. In this embodiment, the first rotating connector 33 has different orientations in the first elevation plane, meaning that the mounting assembly 30 can adjust the orientation of the antenna assembly 01 along the first elevation plane. The first rotating connector 33 and the support 34 can have different installation angles. Specifically, adjacent installation angles can have the same angular difference; in other words, each adjustment adds a fixed variable to the installation angle, such as 10°, 15°, 20°, 25°, etc. A change in the installation angle between the first rotating connector 33 and the support 34 means a corresponding change in the orientation of the first rotating connector 33 in the first elevation plane. Since the antenna assembly 01 is mounted on the first rotating connector 33, its orientation can also be changed accordingly. The orientation of the antenna assembly 01 can refer to the orientation of the transmitting surface 1a.

[0078] In practical use, if Figure 3 From the perspective shown, the antenna device is arranged in the controlled area and is horizontally parallel to the boundary of the controlled area. By adjusting the installation angle of the first rotating connector 33 relative to the support 34, the antenna assembly 01 can be tilted towards the center of the controlled area or towards the direction away from the controlled area. For example, if it is desired that the interference signal be transmitted towards the controlled area, the antenna assembly 01 is adjusted to be tilted towards the controlled area; if it is desired that the interference signal be transmitted away from the controlled area, the antenna assembly 01 is adjusted to be tilted away from the controlled area. Alternatively, it can be done as follows: Figure 3 As shown, the transmitting surface 1a of the antenna assembly 01 faces the sky, meaning that the antenna assembly 01 is neither tilted towards nor away from the controlled area. Therefore, by adjusting the installation angle of the first rotating connector 33 relative to the support 34, this embodiment allows the first antenna assembly 10 and the second antenna assembly 20 to have different orientations in the first elevation plane to adapt to different application scenarios.

[0079] Based on the above embodiments, in order to allow the first rotating connector 33 to have different installation angles relative to the support member 34, such as... Figure 3 ,Figure 6 As shown, the first end of the first rotating connector 33 includes a first mounting surface 3301, which is parallel to the reference plane. The first mounting surface 3301 has multiple first-position through holes 33-4, each located at a different position, for example, at different angular positions centered on the rotation axis of the first rotating connector 33 relative to the support member 34. The support member 34 has a first fixing hole 34-2. When the different first-position through holes 33-4 and the first fixing hole 34-2 are connected by a first fastener, the first rotating connector 33 and the support member 34 have different mounting angles.

[0080] In actual use, when it is necessary to adjust the installation angle of the first rotating connector 33 relative to the support 34, the first fastener can be released from locking the first rotating connector 33 and the support 34, and the first rotating connector 33 can be rotated until the first gear through hole 33-4 at the target position (for example, the first gear through hole 33-4 in the second position in the order from front to back) is aligned with the first fixing hole 34-2. Then, the first fastener is used to fasten the first gear through hole 33-4 at the target position to the first fixing hole 34-2.

[0081] In this specific embodiment, the first pitch plane may be parallel to... Figure 6 The plane of the first mounting surface 3301 shown can also be the plane on which the first mounting surface 3301 is located. It should be noted that in this specific embodiment, the multiple first-position through holes 33-4 can be distributed along the same circumference or on different circumferences, depending on the actual situation. If different first-position through holes 33-4 are distributed on different circumferences, multiple first fixing holes 34-2 can be provided, with one first fixing hole 34-2 corresponding to each circumference. In this way, regardless of which first-position through hole 33-4 is used, it can always be rotated to a position aligned with the first fixing hole 34-2.

[0082] The first fastener in this specific embodiment can be configured as a fastening screw, fastening bolt, or other structure, depending on the actual situation.

[0083] like Figure 6 As shown, by connecting the first fixing hole 34-2 with different first gear through holes 33-4, the installation angle of the first rotating connector 33 relative to the support 34 can be adjusted, so that the second end and the third end of the first rotating connector 33 can have different orientations on the first elevation plane. This makes it convenient to adjust the installation angle of the first antenna assembly 10 and the second antenna assembly 20 on the first elevation plane, thereby adjusting the signal transmission angle. The adjustment process is convenient and easy to operate.

[0084] On the basis of the above-mentioned embodiments, the first end of the first rotating connecting piece 33 comprises two parallel first mounting surfaces 3301, and each first mounting surface 3301 is further provided with a first center through hole 33-6. The second fastener is arranged in the first center through hole 33-6 of the two first mounting surfaces 3301, and all the first gear through holes 33-4 are distributed on a first circular arc with the first center through hole 33-6 as the center.

[0085] In actual use, by rotating the first rotating connecting piece 33 around the axis with the first center through hole 33-6 as the center, different first gear through holes 33-4 can be aligned with the first fixed hole 34-2, facilitating the adjustment of the installation angle of the first rotating connecting piece 33 relative to the support piece 34. The support piece 34 is provided with two first fixed grooves 34-1, and the second fastener is arranged across the two first fixed grooves 34-1.

[0086] The first fixed groove 34-1 can be provided with an opening on the side facing the first rotating connecting piece 33. The second fastener is, for example, a screw rod, a lead screw, etc. In actual use, the second fastener is first arranged in the first center through hole 33-6 of the two first mounting surfaces 3301, and then the first rotating connecting piece 33 with the second fastener inserted is installed to the support piece 34. During the installation process, the second fastener can be arranged across the two first fixed grooves 34-1. Since the first fixed groove 34-1 is provided with an opening, the second fastener can directly enter the first fixed groove 34-1 from the opening of the first fixed groove 34-1, facilitating the installation process and saving time. In addition, the preliminary positioning of the first rotating connecting piece 33 relative to the support piece 34 can also be achieved, ensuring that the first rotating connecting piece 33 can be accurately and quickly rotated to the required angle, and also improving the convenience of adjusting the angle of the first rotating connecting piece 33, making it easier to operate. Next, the first rotating connecting piece 33 can be rotated to align the first gear through hole 33-4 at the target position with the first fixed hole 34-2, and then the first gear through hole 33-4 at the target position is fixed with the first fixed hole 34-2 by using the first fastener, that is, the adjustment of the orientation of the antenna assembly 01 in the first pitch plane is completed.

[0087] In addition, the first end of the first rotating connecting piece 33 comprises two parallel first mounting surfaces 3301, and the support piece 34 is provided with two first fixed grooves 34-1, which can effectively support the second fastener, improving the stability of the structure.

[0088] Specifically, the distance between each first-gear through hole 33-4 and the first central through hole 33-6 is greater than a set threshold, in other words, the distance between each first-gear through hole 33-4 and the first central through hole 33-6 can be relatively large. In this way, after the angle adjustment of the first rotary connecting piece 33 is completed and fixed, the stability can be further increased. For example, the first-gear through hole 33-4 is located at the lower edge of the first mounting surface 3301, and the first central through hole 33-6 is located at a relatively upper position of the first mounting surface 3301.

[0089] On the basis of the above embodiment, one of the support piece 34 and the first rotary connecting piece 33 is provided with the first guide limiting hole 33-5, and the other is provided with the first locking hole 34-3. For example Figure 6 In this embodiment, the first rotary connecting piece 33 is provided with the first guide limiting hole 33-5, and the support piece 34 is provided with the first locking hole 34-3. The first guide limiting hole 33-5 can at least include a through hole extending along a second circular arc, and the second circular arc is arranged with the first circular arc as a common center. The center of the first circular arc and the center of the second circular arc can be the center of the first central through hole 33-6, and the central angle corresponding to the second circular arc covers at least the central angle corresponding to the first circular arc. The first guide limiting hole 33-5 and the first locking hole 34-3 are fixed by the third fastener after the installation angle of the first rotary connecting piece 33 and the support piece 34 is fixed.

[0090] It should be noted that the first guide limiting hole 33-5 is not limited to Figure 6 the structure shown in the above embodiment (i.e., the first guide limiting hole 33-5 is a through hole extending along a second circular arc), but can also be a larger size hole including a through hole extending along a second circular arc. For example, the first guide limiting hole 33-5 can be an elliptical hole, and Figure 6 the through hole extending along the second circular arc shown in the above embodiment is located in the first guide limiting hole 33-5.

[0091] The central angle corresponding to the second circular arc covers at least the central angle corresponding to the first circular arc, for example, the central angle corresponding to the second circular arc can be greater than or equal to the central angle corresponding to the first circular arc. In this embodiment, when adjusting the first rotary connecting piece 33, if the first-gear through hole 33-4 at the target position is aligned with the first fixed hole 34-2 and fixed by the first fastener, the first locking hole 34-3 can be fixed with the first guide limiting hole 33-5 by the third fastener. By fixing the first guide limiting hole 33-5 and the first locking hole 34-3 by the third fastener, the function of auxiliary load bearing can be achieved.

[0092] The central angle corresponding to the second circular arc covers at least the central angle corresponding to the first circular arc, and the first circular arc and the second circular arc have the same center. In this way, when the mounting angle of the first rotating connecting piece 33 relative to the support piece 34 in the first pitch plane is adjusted, no matter which first gear hole 33-4 is aligned with the first fixed hole 34-2, the first locking hole 34-3 can be aligned with the corresponding part of the first guide limiting hole 33-5, so that the first locking hole 34-3 and the first guide limiting hole 33-5 can be fixed after the angle adjustment of the first rotating connecting piece 33 is completed.

[0093] It should be noted that in another embodiment, the central angle of the second circular arc can also be the same as the central angle of the first circular arc, and when the mounting angle of the first rotating connecting piece 33 needs to be adjusted, the third fastener only needs to be loosened, but does not need to be removed. That is, during the adjustment of the first rotating connecting piece 33, the third fastener is still inserted into the first locking hole 34-3 and the first guide limiting hole 33-5. In this way, the third fastener can limit the rotation range of the first rotating connecting piece 33, so that the state of no suitable first gear hole 33-4 aligned with the first fixed hole 34-2 due to too large rotation range can be avoided.

[0094] In a specific embodiment, through the installation assembly 30, the orientation of the antenna assembly 01 in the second pitch plane can also be adjusted. The specific principle is as follows. Figure 3 、 Figure 4 、 Figure 5 As shown in the figure, the installation assembly 30 further includes a second rotating connecting piece 31 and a third rotating connecting piece 32. The fourth end of the second rotating connecting piece 31 is used to install one of the antenna assemblies 01, for example, the fourth end of the second rotating connecting piece 31 is used to install the first antenna assembly 10. The fifth end of the second rotating connecting piece 31 is installed on the second end of the first rotating connecting piece 33. The sixth end of the third rotating connecting piece 32 is used to install another antenna assembly 01 (such as the second antenna assembly 20), and the seventh end of the third rotating connecting piece 32 is installed on the third end of the first rotating connecting piece 33. The second rotating connecting piece 31 and the first rotating connecting piece 33 can have different mounting angles, so that the second rotating connecting piece 31 can have different orientations in the second pitch plane. The second pitch plane is perpendicular to the reference plane. The third rotating connecting piece 32 and the first rotating connecting piece 33 can have different mounting angles, so that the third rotating connecting piece 32 can have different orientations in the second pitch plane.

[0095] In the actual use process of the embodiment, the lower end surface 1b (such as Figure 3The first antenna assembly 10 is connected to the second rotating connector 31. By adjusting the pitch angle of the second rotating connector 31 on the second pitch plane, the orientation of the upper end surface 1a of the first antenna assembly 10 can be changed accordingly, thereby adjusting the coverage range of the signal transmitted by the first antenna assembly 10 on the second pitch plane. The principle of the second antenna assembly 20 is the same, and will not be described again here.

[0096] The second pitch plane is perpendicular to the reference plane, for example... Figure 3 As shown, the second pitch plane is parallel to Figure 3 The projection plane of the shown viewpoint, and the second pitch plane is parallel to... Figure 3 The horizontal direction shown. The first and second directions mentioned in the preceding embodiments are both parallel to, or both located within, the second pitch plane in this specific embodiment. Figure 3 Taking the shown perspective as an example, for the first antenna assembly 10, by adjusting the second rotating connector 31, the first antenna assembly 10 can be rotated counterclockwise relative to the reference plane L (in which case the first antenna assembly 10 will gradually move away from the second antenna assembly 20), or rotated clockwise (in which case the first antenna assembly 10 will gradually move closer to the second antenna assembly 20). For the second antenna assembly 20, by adjusting the third rotating connector 32, the second antenna assembly 20 can be rotated clockwise relative to the reference plane (in which case the second antenna assembly 20 will gradually move away from the first antenna assembly 10), or rotated counterclockwise (in which case the second antenna assembly 20 will gradually move closer to the first antenna assembly 10). Therefore, if it is desired to expand the coverage area of ​​the antenna device, the angle between the first antenna assembly 10 and the second antenna assembly 20 can be increased; if it is desired to reduce the coverage area of ​​the antenna device, the angle between the first antenna assembly 10 and the second antenna assembly 20 can be decreased.

[0097] In this embodiment, when the pitch angle of the second rotating connecting member 31 and the third rotating connecting member 32 in the second pitch plane is adjusted, the orientation of the first antenna assembly 10 and the second antenna assembly 20 in the second pitch plane can be adjusted accordingly, so that the coverage range of the signals emitted by the antenna device in the second pitch plane can be adjusted. If the antenna device is applied to a control area, and the horizontal direction is parallel to the boundary of the control area, the signal coverage range of the antenna device along the boundary of the control area can be adjusted accordingly. In addition, this embodiment can combine the scheme of adjusting the installation angle between the first rotating connecting member 33 and the support member 34 mentioned in the foregoing embodiments. In this way, the angles of the antenna device in two directions can be adjusted, i.e., the orientations in the first pitch plane and the second pitch plane can be adjusted respectively, so that the antenna device can be applied to more application scenarios. For example, taking the application scenario of a control area as an example, if it is desired that the upper end surface la of the antenna assembly 01 faces outward of the control area, the installation angle between the first rotating connecting member 33 and the support member 34 can be adjusted to achieve this purpose; at the same time, if it is desired to increase the coverage range of the entire antenna device along the boundary of the control area, the installation angles of the second rotating connecting member 31 and the third rotating connecting member 32 relative to the first rotating connecting member 33 can be adjusted to achieve this purpose.

[0098] In a specific embodiment, as shown in Figure 4 , Figure 5 In order to enable the second rotating connecting member 31 to have different installation angles relative to the first rotating connecting member 33, the fifth end of the second rotating connecting member 31 includes a second installation surface 31-3, and the second installation surface 31-3 is perpendicular to the reference plane. The second installation surface 31-3 is provided with a plurality of second gear through holes 31-32, and different second gear through holes 31-32 are arranged at different positions, for example, different second gear through holes 31-32 are arranged at different angular positions centered on the rotation axis of the second rotating connecting member 31 relative to the first rotating connecting member 33. The second end of the first rotating connecting member 33 is provided with a second fixed hole 33-3. When different second gear through holes 31-32 and the second fixed hole 33-3 are connected by the fourth fastener, the second rotating connecting member 31 and the first rotating connecting member 33 have different installation angles.

[0099] In actual use, when it is necessary to adjust the installation angle of the second rotating connecting member 31 relative to the first rotating connecting member 33, the fourth fastener can be removed to lock the second rotating connecting member 31 and the first rotating connecting member 33, and the second rotating connecting member 31 can be rotated until the second gear through hole 31-32 at the target position is aligned with the second fixed hole 33-3, and then the fourth fastener is used to fasten the second gear through hole 31-32 at the target position and the second fixed hole 33-3.

[0100] In actual use, the fourth fastener connection can be provided as a pin shaft, a screw, a bolt or the like, and is determined according to actual conditions.

[0101] By making the different second gear through holes 31-32 and the second fixed hole 33-3 connected by the fourth fastener, the second rotating connecting piece 31 can be installed to different angular positions relative to the first rotating connecting piece 33 in the second pitch plane, so as to adjust the signal emission angle of the antenna assembly 01 installed on the second rotating connecting piece 31. Further, the seventh end of the third rotating connecting piece 32 comprises a third mounting surface 32-3, and the third mounting surface 32-3 is perpendicular to the reference plane. The third mounting surface 32-3 is provided with a plurality of third gear through holes 32-32 located on the third mounting surface 32-3. Different third gear through holes 32-32 are arranged at different positions, for example, different third gear through holes 32-32 are arranged at different angular positions with the rotating axis of the third rotating connecting piece 32 relative to the first rotating connecting piece 33 as the center. The third end of the first rotating connecting piece 33 is provided with a third fixed hole 33-9. When the different third gear through holes 32-32 and the third fixed hole 33-9 are connected by the fifth fastener, the third rotating connecting piece 32 and the first rotating connecting piece 33 have different mounting angles.

[0102] In actual use, when it is necessary to adjust the mounting angle of the third rotating connecting piece 32 relative to the first rotating connecting piece 33, the fifth fastener can be removed to lock the third rotating connecting piece 32 relative to the first rotating connecting piece 33. The third rotating connecting piece 32 is rotated to the target position of the third gear through hole 32-32 aligned with the third fixed hole 33-9, and then the fifth fastener is used to fasten the third gear through hole 32-32 at the target position and the third fixed hole 33-9.

[0103] In actual use, the fifth fastener connection can be provided as a pin shaft, a screw, a bolt or the like, and is determined according to actual conditions.

[0104] By making the different third gear through holes 32-32 and the third fixed hole 33-9 connected by the fifth fastener, the third rotating connecting piece 32 can be installed to different angular positions relative to the first rotating connecting piece 33 in the second pitch plane, so as to adjust the signal emission angle of the antenna assembly 01 installed on the third rotating connecting piece 32.

[0105] Further, as shown in FIG. 1, the first rotating connecting piece 33 is provided with a first fixed hole 33-1, and the second rotating connecting piece 31 is provided with a first gear through hole 31-1. When the first gear through hole 31-1 and the first fixed hole 33-1 are connected by the first fastener, the second rotating connecting piece 31 and the first rotating connecting piece 33 have different mounting angles. Figure 4 , Figure 5As shown, the fifth end of the second rotating connecting piece 31 includes two parallel second mounting surfaces 31-3, and each second mounting surface 31-3 is further provided with a second center through hole 31-31, and the sixth fastener is arranged in the second center through hole 31-31 of the two second mounting surfaces 31-3. All the second gear through holes 31-32 are distributed on a third circular arc with the second center through hole 31-31 as the center. In actual use, by rotating the second rotating connecting piece 31 around the axis with the second center through hole 31-31 as the center, different second gear through holes 31-32 can be aligned with the second fixed hole 33-3, so as to facilitate the adjustment of the installation angle of the second rotating connecting piece 31 relative to the first rotating connecting piece 33. The second end of the first rotating connecting piece 33 is provided with two second fixed grooves 33-1, and the sixth fastener is arranged across the two second fixed grooves 33-1.

[0106] In actual use, the sixth fastener is first arranged in the second center through hole 31-31 of the two second mounting surfaces 31-3, and then the second rotating connecting piece 31 with the sixth fastener inserted is installed to the first rotating connecting piece 33. During the installation process, the sixth fastener is arranged across the two second fixed grooves 33-1. Since the second fixed groove 33-1 is provided with an opening, the sixth fastener can directly enter the second fixed groove 33-1 from the opening of the second fixed groove 33-1, and the installation process is convenient and time-saving. In addition, by arranging the second rotating connecting piece 31 across the two second fixed grooves 33-1 through the sixth fastener, the preliminary positioning of the second rotating connecting piece 31 relative to the first rotating connecting piece 33 can be realized, so as to ensure that the second rotating connecting piece 31 can be accurately and quickly rotated to the required angle, and also facilitate the adjustment of the angle.

[0107] In addition, the fifth end of the second rotating connecting piece 31 includes two parallel second mounting surfaces 31-3, and the second end of the first rotating connecting piece 33 is provided with two second fixed grooves 33-1, so that the sixth fastener can be effectively supported, and the stability of the structure is improved.

[0108] Further, the fifth end of the second rotating connecting piece 31 can include a first fixed part 31-1 and a first rotating part 31-2. The first fixed part 31-1 can be installed with the first antenna assembly 10. The first rotating part 31-2 can include the above-mentioned two second mounting surfaces 31-3.

[0109] The seventh end of the third rotating connecting piece 32 comprises two parallel third mounting surfaces 32-3, and each third mounting surface 32-3 is further provided with a third center through hole 32-31. The seventh fastener is arranged in the third center through hole 32-31 of the two third mounting surfaces 32-3. All the third gear through holes 32-32 are distributed on a fourth circular arc with the third center through hole 32-31 as the center. In actual use, by rotating the third rotating connecting piece 32 around the axis with the third center through hole 32-31 as the center, different third gear through holes 32-32 can be aligned with the third fixed hole 33-9, so as to facilitate the adjustment of the installation angle of the third rotating connecting piece 32 relative to the first rotating connecting piece 33. The third end of the first rotating connecting piece 33 is provided with two third fixed grooves 33-7, and the seventh fastener is arranged across the two third fixed grooves 33-7.

[0110] In actual use, the seventh fastener is first arranged in the third center through hole 32-31 of the two third mounting surfaces 32-3, and then the third rotating connecting piece 32 with the seventh fastener inserted is installed to the first rotating connecting piece 33. During the installation process, the seventh fastener is arranged across the two third fixed grooves 33-7. Since the third fixed groove 33-7 is provided with an opening, the seventh fastener can directly enter the third fixed groove 33-7 through the opening of the third fixed groove 33-7, so that the installation process is convenient and time-saving. In addition, the preliminary positioning of the third rotating connecting piece 32 relative to the first rotating connecting piece 33 can be realized, so as to ensure that the third rotating connecting piece 32 can be accurately and quickly rotated to the required angle, and the adjustment of the angle is also facilitated.

[0111] In addition, the seventh end of the third rotating connecting piece 32 comprises two parallel third mounting surfaces 32-3, and the third end of the first rotating connecting piece 33 is provided with two third fixed grooves 33-7, so that the seventh fastener can be effectively supported, and the stability of the structure is improved.

[0112] Further, the seventh end of the third rotating connecting piece 32 can comprise a second fixed part 32-1 and a second rotating part 32-2. The second fixed part 32-1 can be installed with the second antenna assembly 20. The second rotating part 32-2 can comprise the above-mentioned two third mounting surfaces 32-3.

[0113] On the basis of the above-mentioned embodiments, one of the second end of the first rotating connecting piece 33 and the second rotating connecting piece 31 can be further provided with a second guide limiting hole 31-33, and the other is provided with a second locking hole 33-2. Among them, the second guide limiting hole 31-33 is arranged along the fifth circular arc, the fifth circular arc and the third circular arc are arranged with the same center, and the center can be the center of the second center through hole 31-31, and the central angle corresponding to the fifth circular arc covers the central angle corresponding to the third circular arc at least. The second guide limiting hole 31-33 and the second locking hole 33-2 are fixed by the eighth fastener after the installation angle of the first rotating connecting piece 33 and the second rotating connecting piece 31 is fixed. It needs to be explained that the second guide limiting hole 31-33 is not limited to the structure shown in the figure, but can also be a larger size hole containing the through hole as shown in the figure. Figure 5 Figure 5

[0114] The central angle corresponding to the fifth circular arc covers the central angle corresponding to the third circular arc at least in the specific embodiment, when adjusting the installation angle of the second rotating connecting piece 31 relative to the first rotating connecting piece 33 in the second pitch plane, no matter which second gear hole 31-32 is aligned with the second fixed hole 33-3, it can be ensured that the second locking hole 33-2 can be aligned with the corresponding part of the second guide limiting hole 31-33, so that the second locking hole 33-2 and the second guide limiting hole 31-33 can be fixed by the eighth fastener after the angle adjustment of the second rotating connecting piece 31 is completed. In the specific embodiment, the eighth fastener connects the second guide limiting hole 31-33 and the second locking hole 33-2, and the eighth fastener can assist the second rotating connecting piece 31 to bear the weight.

[0115] It needs to be explained that in another embodiment, the central angle of the fifth circular arc can be the same as the central angle of the third circular arc, and when the installation angle of the second rotating connecting piece 31 needs to be adjusted, only the eighth fastener needs to be loosened, but it does not need to be disassembled. During the adjustment of the second rotating connecting piece 31, the eighth fastener is still inserted into the second guide limiting hole 31-33 and the second locking hole 33-2. In this way, the eighth fastener can play a limiting role to limit the rotation amplitude of the second rotating connecting piece 31, so that the state that there is no suitable second gear hole 31-32 aligned with the second fixed hole 33-3 due to too large rotation amplitude can be avoided.

[0116] ​​The third end of the first rotating connecting piece 33 and one of the third rotating connecting pieces 32 are provided with a third guide limiting hole 32-33, and the other is provided with a third locking hole 33-8. The third guide limiting hole 32-33 is arranged along a sixth circular arc, the sixth circular arc is arranged with the fourth circular arc as a common center, and the common center can be the center of the third central through hole 32-31, and the central angle corresponding to the sixth circular arc covers at least the central angle corresponding to the fourth circular arc. The third guide limiting hole 32-33 and the third locking hole 33-8 are fixedly connected by a ninth fastener after the mounting angle of the third end of the first rotating connecting piece 33 and the third rotating connecting piece 32 is fixed. It should be noted that the third guide limiting hole 32-33 is not limited to the structure shown in Figure 5 FIG. 6, but can also be a larger size hole containing a through hole as shown in Figure 5 FIG. 7.

[0117] In the specific embodiment, the central angle corresponding to the sixth circular arc covers at least the central angle corresponding to the fourth circular arc, and when adjusting the mounting angle of the third rotating connecting piece 32 relative to the first rotating connecting piece 33 in the second pitch plane, no matter which third gear hole 32-32 is aligned with the third fixed hole 33-9, the third locking hole 33-8 can be aligned with the corresponding part of the third guide limiting hole 32-33, so that the third locking hole 33-8 and the third guide limiting hole 32-33 can be fixed by the ninth fastener after the angle adjustment of the third rotating connecting piece 32 is completed.

[0118] In the specific embodiment, the third guide limiting hole 32-33 and the third locking hole 33-8 are connected by the ninth fastener, and the ninth fastener can assist in bearing the weight of the third rotating connecting piece 32.

[0119] It should be noted that in another embodiment, the central angle of the sixth circular arc can be the same as the central angle of the fourth circular arc, and when the mounting angle of the third rotating connecting piece 32 needs to be adjusted, only the ninth fastener needs to be loosened, but the ninth fastener does not need to be disassembled, that is, during the adjustment of the third rotating connecting piece 32, the ninth fastener is still inserted into the third guide limiting hole 32-33 and the third locking hole 33-8. In this way, the ninth fastener can limit the rotation amplitude of the third rotating connecting piece 32, so that the state of not having a suitable third gear hole 32-32 aligned with the third fixed hole 33-9 due to too large rotation amplitude can be avoided.

[0120] It should be noted that the specific structure of the second rotating connecting piece 31 and the third rotating connecting piece 32 is the same as the specific structure principle of the first rotating connecting piece 33, which will not be described here.

[0121] Next, the specific structure of the second rotating connecting piece 31 and the third rotating connecting piece 32 will be described in detail. Figures 3-5The shown embodiment is an example for illustrating the principle of using the antenna device.

[0122] During use, if it is necessary to adjust the orientation of the antenna assembly 01 along the first tilt plane, the mounting angle of the first rotating connecting member 33 relative to the support member 34 can be adjusted. If it is necessary to adjust the orientation of the antenna assembly 01 along the second tilt plane, the mounting angle of the second rotating connecting member 31 (and / or the third rotating connecting member 32) relative to the first rotating connecting member 33 can be adjusted. Next, the principle of angle adjustment will be described in detail by taking the adjustment of the mounting angle of the first rotating connecting member 33 relative to the support member 34 as an example. First, the first fastener and the third fastener are disassembled (or the third fastener can also not be disassembled, but only loosened), and the first rotating connecting member 31 is ensured to be arranged on the two first fixing grooves 34-1 of the support member 34 through the second fastener for preliminary positioning. Next, the first rotating connecting member 33 is rotated until the first gear position through hole 33-4 of the target position is aligned with the first fixed hole 34-2, and then the first gear position through hole 33-4 of the target position is fixed with the first fixed hole 34-2 by using the first fastener, and the first guide limiting hole 33-5 and the first locking hole 34-3 are fixed by using the third fastener, thus completing the entire work of adjusting the mounting angle of the first rotating connecting member 33. The principle of adjusting the mounting angle of the second rotating connecting member 31 and the third rotating connecting member 32 relative to the first rotating connecting member 33 is similar to that of the first rotating connecting member 33, and thus will not be described here.

[0123] In addition to the above-mentioned antenna device, the present application also provides an aircraft countermeasure device comprising the above-mentioned antenna device and a control device 50, wherein the control device 50 is electrically connected with the antenna device, and the control device 50 is used for controlling the antenna device to emit signals. The structures of other parts of the aircraft countermeasure device can refer to the prior art, and thus will not be described here.

[0124] As shown in the Figure 1 The aircraft countermeasure device can further comprise a fixing device 40. The mounting assembly 30 and the control device 50 are both mounted on the fixing device 40.
