Description

Technical Field

[0001] This application relates to the field of wireless equipment technology, specifically to an antenna and a drone detection system. Background Technology

[0002] With the development of radio technology, antennas are being widely used in an increasing number of fields. Taking the field of drones as an example, the types and usage scenarios of drones are gradually increasing, and correspondingly, the dangers they pose are also gradually increasing. Therefore, for some special environmental areas, drone detection becomes particularly important to ensure the safety of the area.

[0003] Antennas are a key component for drone detection. Drone detection generally requires outdoor operations, and considering the complexity and variability of the outdoor environment, higher requirements are placed on the waterproof performance of antennas.

[0004] Most existing antennas ensure their waterproof performance by clamping sealing rings at the assembly gaps of their housings. However, as the usage time increases, the sealing rings will age, such as developing cracks, hardening, or becoming brittle, which will lead to seal failure and affect the normal operation of the antenna.

[0008] In one alternative embodiment, a first connecting post is provided on the bottom shell, and a second connecting post is provided on the inner side of the top cover. The first connecting post has a first connecting hole that runs vertically through it, and the second connecting post has a second connecting hole that is open only at its lower end. The first connecting hole is used for fasteners to pass through from the bottom of the bottom shell and connect with the second connecting hole, so that the bottom shell and the top cover are fixed to each other.

[0009] In one alternative embodiment, multiple first connecting posts are evenly distributed along the inner circumference of the first waterproof rib, and multiple second connecting posts are evenly distributed along the inner circumference of the second waterproof rib. The multiple first connecting posts and the multiple second connecting posts are connected one-to-one by fasteners.

[0010] In one alternative embodiment, a mounting post is provided on the inner side of the bottom shell, and a first mounting hole with an opening only at the top is provided on the mounting post. A second mounting hole is provided on the antenna plate, which is used for fasteners to pass through from the top of the antenna plate downward and connect with the first mounting hole, so that the antenna plate is fixed to the bottom shell.

[0011] In one alternative embodiment, the inner side of the bottom shell is provided with first reinforcing ribs arranged in a cross pattern, and multiple mounting posts are evenly distributed around the first reinforcing ribs. There are multiple second mounting holes, which are connected one-to-one with the first mounting holes on the multiple mounting posts by fasteners. And / or, the inner side of the top cover is provided with second reinforcing ribs, and a pressing post is provided on the inner side of the top cover facing the mounting posts, the pressing post pressing against the upper surface of the antenna plate.

[0012] In one alternative embodiment, the antenna also includes a handle, the bottom of the base housing having a connection blind hole at the rear end, and the handle having a connection through hole for fasteners to pass through from below and connect to the connection blind hole, so as to fix the handle to the base housing.

[0013] In one alternative embodiment, the bottom shell has a limiting groove at the rear end, and a connecting block is provided at the front end of the top of the handle. The connecting block is embedded in the limiting groove, a blind hole is provided at the bottom of the limiting groove, and a through hole is provided on the connecting block. The limiting groove is U-shaped with its opening facing the rear end of the bottom shell. The part of the bottom shell enclosed by the limiting groove forms a clearance part, which is adjacent to the rear side wall of the bottom shell. A connector is provided through the rear side wall. The clearance part provides the installation space required for the connector on the inside. The connector is internally connected to the antenna board for signal connection. The connector is used to connect to external devices for signal connection via a wire harness. A wire harness groove is provided at the top of the handle. The wire harness groove is used to allow the wire harness to enter and guide and limit the wire harness.

[0014] In one alternative embodiment, the antenna board includes a circuit board and an antenna body, the antenna body being integrated onto the circuit board. The antenna body includes a transmission line and multiple patches distributed on both sides of the transmission line and perpendicular to the transmission line, with at least some of the patches having their ends bent inward.

[0015] According to another aspect of the embodiments of this application, a drone detection system is provided, characterized in that it includes: a signal processing device and an antenna as described above, wherein the signal processing device and the antenna board are connected by a wiring harness.

[0016] In the antenna provided in this application embodiment, a first waterproof rib and a second waterproof rib are respectively formed by protruding on the two edges where the bottom shell and the top cover meet. The second waterproof rib covers the outer periphery of the first waterproof rib. When rainwater falls on the top cover, it will first flow down the surface of the top cover to the joint between the edge of the top cover and the bottom shell. Under the obstruction of the second waterproof rib, the rainwater flowing to the joint will drip down the bottom shell under the action of gravity. Of course, due to the ambient wind or the slight tilt of the antenna, some rainwater will flow in from the joint between the top cover and the bottom shell. Similarly, since the second waterproof rib on the edge of the top cover covers the outer periphery of the first waterproof rib on the edge of the bottom shell, the first waterproof rib will block the inflowing rainwater in the gap between the first waterproof rib and the second waterproof rib, preventing rainwater from directly entering the internal space. This allows the antenna's rainproof performance to be guaranteed while reducing the sealing requirements of the bottom shell and the top cover assembly. This achieves the goal of reducing the processing and manufacturing precision requirements while providing reliable protection for the operation of the antenna board.

[0017] Furthermore, the antenna provided in this application embodiment forms a space for accommodating the antenna plate by fastening the top cover and the bottom shell together, thereby providing protection for the antenna plate. Based on the fastening connection between the top cover and the bottom shell, the second waterproof rib protruding from the edge of the top cover covers the outer periphery of the first waterproof rib protruding from the edge of the bottom shell, so that the joint between the top cover and the bottom shell forms a structure that can naturally block rainwater from entering. Compared with the method of achieving sealing by using an interference fit of a sealing ring, this setting method does not require the second waterproof rib and the first waterproof rib to be squeezed and stressed during assembly, resulting in better structural stability. Moreover, it does not require the use of soft rubber materials similar to sealing rings, but can use materials with better physical and chemical properties, such as hard plastics or metals, thereby extending the service life of the antenna and ensuring that it still has reliable rainproof capabilities after long-term use.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0047] To improve the antenna's rainproof performance, this application incorporates a special structural design at the joints between the antenna's housings, based on the antenna's usage conditions. This design ensures that rainwater falling on the housings will slide off the housings without flowing into or seeping into them and affecting the antenna's operation.

[0048] According to one aspect of the embodiments of this application, an antenna is provided, which includes, but is not limited to, wireless devices used in fields such as drone detection, mobile communication, Wi-Fi extension, and the Internet of Things. Please refer to [link / reference] for details. Figure 1 and Figure 2 The figure shows the three-dimensional structure and the exploded structure of the antenna respectively. As shown in the figure, the antenna 100 includes: a bottom shell 110, a top cover 120 and an antenna plate 130. The top cover 120 is fastened to the bottom shell 110, and the antenna plate 130 is housed in the internal space formed by the fastening of the top cover 120 and the bottom shell 110.

[0049] Antenna 100 can be Figure 1 and Figure 2 The handheld antenna shown in the figure, used in a drone detection system, corresponds to this usage scenario. The bottom shell 110 and top cover 120 are essentially horizontally arranged plate-like structures, with the bottom shell 110 and top cover 120 having a narrow front end and a wide rear end shape adapted to the antenna plate 130. The following figures and illustrations use this handheld antenna as an example for explanation; however, this does not constitute a limitation on the specific shape or application scenario of the antenna 100.

[0050] Please continue reading. Figure 2 And further reading Figure 3 , Figure 3 The exploded structure of the bottom shell 110 and the top cover 120 is shown from the bottom view. As shown in the figure, a first waterproof rib 111 and a second waterproof rib 121 are respectively protruding on the two edges where the bottom shell 110 and the top cover 120 are joined. The first waterproof rib 111 is located on the bottom shell 110 and the second waterproof rib 121 is located on the top cover 120.

[0051] Please continue reading. Figure 4 The figure shows the cross-sectional structure at the junction of the bottom shell 110 and the top cover 120. The second waterproof rib 121 covers the outer periphery of the first waterproof rib 111. Specifically, after the second waterproof rib 121 covers the outer periphery of the first waterproof rib 111, the two can be assembled and fixed by ultrasonic welding, bonding and other methods.

[0052] With this setting, when rainwater... Figure 4 As indicated by the dashed arrow, after the rainwater falls onto the top cover 120, it will first flow down the surface of the top cover 120 to the junction of the top cover 120 edge and the bottom shell 110. Because the second waterproof rib 121 on the top cover 120 covers the outer periphery of the first waterproof rib 111 on the bottom shell 110, the rainwater flowing to the junction will mostly drip down the bottom shell 110 under the influence of gravity due to the obstruction of the second waterproof rib 121. Of course, due to factors such as ambient wind or a slight tilt of the antenna 100, some rainwater will also flow into the junction of the top cover 120 and the bottom shell 110. Similarly, since the second waterproof rib 121 on the edge of the top cover 120 covers the outer periphery of the first waterproof rib 111 on the edge of the bottom shell 110, the first waterproof rib 111 will block the inflowing rainwater at the gap between the first waterproof rib 111 and the second waterproof rib 121, preventing rainwater from directly entering the internal space. This allows the waterproof performance of the antenna 100 to be guaranteed while reducing the sealing requirements of the assembly between the bottom shell 110 and the top cover 120. This reduces the requirements for manufacturing precision while providing reliable protection for the operation of the antenna board 130.

[0053] The antenna 100 provided in this application embodiment forms a space for accommodating the antenna plate 130 by fastening the top cover 120 and the bottom shell 110 together, thereby providing protection for the antenna plate 130. Based on the fastening connection between the top cover 120 and the bottom shell 110, the second waterproof rib 121 protruding from the edge of the top cover 120 covers the outer periphery of the first waterproof rib 111 protruding from the edge of the bottom shell 110, so that the joint between the top cover 120 and the bottom shell 110 forms a structure that can naturally block rainwater from entering. Compared with the method of achieving sealing by using an interference fit of a sealing ring, this arrangement does not require the second waterproof rib 121 and the first waterproof rib 111 to be subjected to compression stress during assembly, resulting in better structural stability. Moreover, it does not require the use of soft rubber materials similar to sealing rings, but can use materials with better physical and chemical properties, such as hard plastics or metals, thereby extending the service life of the antenna 100 and ensuring that it still has reliable rainproof capability after long-term use.

[0054] To allow rainwater to slide more effectively down the top cover 120 and the bottom shell 110, such as Figure 4 As shown, the edge of the bottom shell 110 can extend obliquely to form a first connecting wall 112, and the edge of the top cover 120 extends obliquely to form a second connecting wall 122. A first waterproof rib 111 is disposed on the first connecting wall 112, and a second waterproof rib 121 is disposed on the second connecting wall 122. The second waterproof rib 121 is fastened to the outer periphery of the first waterproof rib 111.

[0055] from Figure 4 As can be seen from the direction of rainwater movement indicated by the dashed arrow, after the top cover 120 and the bottom shell 110 are assembled by setting the inclined second connecting wall 122 and the first connecting wall 112 respectively, and by interlocking the second waterproof rib 121 and the first waterproof rib 111 on them, more rainwater can flow along the second connecting wall 122 to the joint between the top cover 120 and the bottom shell 110 and drip directly down, rather than easily entering the assembly gap between the two, thereby better ensuring the rainproof performance of the antenna 100.

[0056] To ensure the aesthetics of antenna 100, such as Figure 4As shown, the outer periphery of the second waterproof rib 121 is recessed inward relative to the outer periphery of the top cover 120, so that after the second waterproof rib 121 covers the outer periphery of the first waterproof rib 111, a groove 140 is formed on the outer periphery of the joint between the bottom shell 110 and the top cover 120. The purpose of this design is to reduce the impact of misalignment on the overall visual appearance of the product when the edges of the bottom shell 110 and the top cover 120 are not aligned due to manufacturing or assembly errors. In other words, from the perspective of human visual observation, the groove 140 makes the misalignment of the two edges less noticeable, thereby reducing the impact of manufacturing and assembly errors of the bottom shell 110 and the top cover 120 on the overall aesthetics of the antenna 100 and improving the product's appearance.

[0057] As mentioned above, the top cover 120 and the bottom shell 110 can be assembled and fixed by ultrasonic welding or bonding. For ultrasonic welding, there are certain requirements for materials, dimensional accuracy and process control, which undoubtedly increases the production cost and assembly difficulty of the top cover 120 and the bottom shell 110. Although bonding is not expensive, it is more complicated to operate and will affect the assembly efficiency.

[0058] In view of the above problems, in order to achieve assembly at a lower cost and more conveniently while ensuring that the antenna 100 has good rainproof performance, this application further proposes an implementation method, which can be found again in detail. Figure 2 and 3 The bottom shell 110 is provided with a first connecting post 113, and the top cover 120 is provided with a second connecting post 123. The first connecting post 113 has a first connecting hole 1131 that runs vertically through the bottom, and the second connecting post 123 has a second connecting hole 1231 that opens only at the bottom. The first connecting hole 1131 allows a fastener (not shown) to pass through from the bottom of the bottom shell 110 and connect with the second connecting hole 1231. Specifically, the fastener can be a screw that passes through the first connecting hole 1131 and is threaded to the second connecting hole 1231, or a rivet or expansion bolt that passes through the first connecting hole 1131 and is riveted to the second connecting hole 1231, or a snap fastener that passes through the first connecting hole 1131 and is snapped into the second connecting hole 1231, etc. The specific type is not limited here.

[0059] By inserting fasteners into the first connecting hole 1131 and connecting them to the second connecting hole 1231, the bottom shell 110 and the top cover 120 can be easily and conveniently assembled and fixed together. The second connecting hole 1231 is a blind hole with an opening only at the bottom, so there are no openings on the upper surface of the top cover 120. The fasteners are inserted from the bottom up for assembly. Therefore, rainwater falling from above the top cover 120 has no way to enter the interior through the upper surface of the top cover 120. After passing through the joint between the top cover 120 and the bottom shell 110, the rainwater will drip down due to gravity and will not flow to the lower surface of the bottom shell 110, nor can it enter the interior space from the first connecting hole 1131 on the lower surface of the bottom shell 110. This achieves convenient assembly of the bottom shell 110 and the top cover 120 while ensuring rainproof capability.

[0060] Furthermore, to ensure a tighter fit between the interlocking edges of the bottom shell 110 and the top cover 120, and more importantly, to ensure a tighter fit between the second waterproof rib 121 and the surface of the bottom shell 110 located on the outer periphery of the first waterproof rib 111, so as to better prevent rainwater or dust from entering through gaps, such as... Figure 2 and Figure 3 As shown, multiple first connecting posts 113 can be evenly distributed along the inner circumference of the first waterproof rib 111, and multiple second connecting posts 123 are equally distributed along the inner circumference of the second waterproof rib 121. Multiple first connecting posts 113 and multiple second connecting posts 123 are connected one-to-one by fasteners, so that the top cover 120 and the bottom shell 110 form a fixed connection at multiple points along their joint edges, thereby ensuring that the top cover 120 and the bottom shell 110 can be tightly abutted together at the interlocking position, preventing rainwater, dust and other substances from easily entering the interior from there.

[0061] To ensure the antenna 100 is waterproof, the antenna plate 130 is reliably installed and fixed within the internal space formed by the snap-fit ​​between the top cover 120 and the bottom shell 110, such as... Figure 2 As shown, a mounting post 114 is provided on the inner side of the bottom shell 110. The mounting post 114 has a first mounting hole 1141 with only the upper end open. The antenna plate 130 has a second mounting hole 131. The second mounting hole 131 allows a fastener (which can have the same structure as the fastener mentioned above that fixes the first connecting hole 1131 and the second connecting hole 1231 to each other) to pass through from the top of the antenna plate 130 and connect to the first mounting hole 1141, so that the antenna plate 130 is fixed on the bottom shell 110.

[0062] The fasteners connecting the second mounting hole 131 and the first mounting hole 1141 can be made of non-metallic material to avoid affecting the signal radiation of the antenna board 130.

[0063] In this embodiment, the antenna board 130 is installed by means of the first mounting hole 1141 on the mounting post 114 inside the bottom shell 110, which eliminates the need to drill holes in the top cover 120, thereby ensuring the rainproof capability of the top cover 120. At the same time, setting the first mounting hole 1141 as a blind hole with only an opening at the top can ensure the neatness and aesthetics of the bottom shell 110.

[0064] for Figure 2 and Figure 3 In the specific embodiment shown, during assembly, the antenna plate 130 can be installed and fixed on the bottom shell 110 using fasteners. Then, the top cover 120 is snapped onto the bottom shell 110, and the bottom shell 110 and the top cover 120 are assembled and fixed by fasteners screwed in from below the bottom shell 110. This completes the overall assembly of the antenna 100, and the whole process is very convenient.

[0065] Please refer to it again. Figure 2 The inner side of the bottom shell 110 can be provided with first reinforcing ribs 115 in a cross pattern. The first reinforcing ribs 115 are used to enhance the load-bearing capacity of the bottom shell 110, preventing the bottom shell 110 from deforming inward due to external pressure, thereby compressing the antenna plate 130 inside the shell. Furthermore, to ensure that the arrangement of the first reinforcing ribs 115 can better protect the antenna plate 130, such as... Figure 2 As shown, there can be multiple mounting posts 114 evenly distributed around the first reinforcing rib 115. Correspondingly, there are also multiple second mounting holes 131 that mate with the first mounting holes 1141 on each second mounting post 114, and the multiple second mounting holes 131 are connected to the multiple first mounting holes 1141 one-to-one by fasteners. After assembly in this way, the first reinforcing rib 115 can more fully cover the bottom of the antenna plate 130, thereby ensuring that the bottom shell 110 is not easily deformed by force and thus does not damage the antenna plate 130.

[0066] Similarly, to prevent the top cover 120 from deforming inward under pressure and damaging the antenna plate 130, such as Figure 3 As shown, a second reinforcing rib 124 may be provided on the inner side of the top cover 120 to enhance the top cover 120's ability to resist pressure.

[0067] Furthermore, to prevent the fasteners connecting the antenna plate 130 and the bottom shell 110 from loosening and causing the antenna plate 130 to wobble internally, such as... Figure 3As shown, a pressure post 125 can also be provided on the inner side of the top cover 120. The pressure post 125 is used to press against the upper surface of the antenna plate 130 to prevent the antenna plate 130 from shaking due to loose connections. Specifically, the pressure post 125 can be arranged opposite to the mounting post 114 so that the antenna plate 130 is clamped by the cooperation of the pressure post 125 and the mounting post 114, avoiding the pressure post 125 pressing against the unsupported position at the bottom of the antenna plate 130 and causing the antenna plate 130 to bend.

[0068] like Figure 1 and Figure 2 As shown, antenna 100 may also include handle 150; please refer to further details. Figure 5 and Figure 6 The figure shows the exploded structure of the handle 150 and the base shell 110 from two perspectives. As shown, the base shell 110 has a blind hole 116 at the bottom of its rear end, and the handle 150 has a through hole 151. The through hole 151 is used for fasteners 152 to pass through from below and connect to the blind hole 116, so that the handle 150 is fixed to the base shell 110. The fasteners 152 here are similar to the fasteners mentioned above, and can be screws, rivets, expansion bolts, snap fasteners, etc., and are not specifically limited.

[0069] By mounting the handle 150 at the bottom of the rear end of the bottom shell 110, the convenience of using the handheld antenna 100 can be ensured. In addition, by using the connection blind hole 116 opened on the bottom shell 110 to mount and fix the handle 150, rainwater can be prevented from entering from the assembly position of the two.

[0070] Furthermore, such as Figure 5 and Figure 6As shown, the bottom shell 110 has a limiting groove 117 at its rear bottom. A connecting block 153 is provided at the front end of the top of the handle 150. The connecting block 153 is embedded in the limiting groove 117. A connecting blind hole 116 is provided at the bottom of the limiting groove 117, and a connecting through hole 151 is provided on the connecting block 153. The limiting groove 117 is U-shaped with its opening facing the rear end of the bottom shell 110. Here, the "opening" refers to the direction in which the opening of the "U" shape faces, not the direction in which the groove opening of the limiting groove 117 faces. The portion of the bottom shell 110 enclosed by the limiting groove 117 forms a clearance portion 118. Here, the portion enclosed by the limiting groove 117 also refers to the portion enclosed by the "U" shape. The clearance portion 118 is adjacent to the rear side wall 119 of the bottom shell 110. A connector 160 is provided through the rear side wall 119, and the clearance portion 118 provides the installation space required for the connector 160 (position M in Figure 6) on its inner side. Connector 160 is internally connected to antenna board 130 for signal connection. Connector 160 is also used to connect to external devices (such as some electronic devices that can transmit and receive signals through antenna 100) via wire harness to realize signal transmission between external devices and antenna board 130.

[0071] In this embodiment, a limiting groove 117 is provided at the rear end of the bottom shell 110, and a connecting block 153 is provided at the front end of the top of the handle 150. Based on the accurate positioning achieved by embedding the connecting block 153 into the limiting groove 117, the two are reliably fixed by using fasteners 152, thereby achieving the purpose of convenient assembly of the handle 150 on the bottom shell 110.

[0072] Considering that the antenna board 130 needs to transmit signals with external devices, in order to assemble the connector 160 without increasing the overall thickness of the antenna 100 and ensuring its overall aesthetics, in this embodiment, the limiting groove 117 is set in a "U" shape. The clearance portion 118 enclosed by the limiting groove 117 does not encroach on the interior of the bottom shell 110. Based on this, the clearance portion 118 can be designed adjacent to the rear side wall 119, and the connector 160 is disposed through the rear side wall 119. This ensures that sufficient installation space for the connector 160 is provided on the inside by the clearance portion 118 without increasing the overall thickness of the product. Furthermore, this design can completely cover the uneven parts of the clearance portion 118 and the limiting groove 117 by the connecting block 153 embedded in the limiting groove 117, thereby ensuring the neatness and aesthetics of the overall shape of the antenna 100.

[0073] Furthermore, such as Figure 7As shown, the wire harness 200 connecting the external device and the connector 160 is connected to the connector 160 from the rear end. Based on this, in order to prevent the wire harness 200 from being damaged by bending under force, a wire harness groove 154 can be provided at the top of the handle 150. The wire harness groove 154 allows the wire harness 200 to enter and guides and limits the wire harness 200 to avoid damage from excessive bending.

[0074] Regarding the structure of the antenna plate 130, this application proposes an implementation method, specifically as follows: Figure 8 As shown in the three-dimensional structure of the antenna board 130, the antenna board 130 may include a circuit board 132 and an antenna body 133. The antenna body 133 is integrated on the circuit board 132. The antenna body 133 includes a transmission line 1331 and multiple patches 1332 distributed on both sides of the transmission line 1331 and perpendicular to the transmission line 1331. The transmission line 1331 serves as an energy transmission channel between the patches 1332 and external circuits, ensuring efficient signal input or output. The patches 1332 are responsible for radiating energy. At least some of the ends of the patches 1332 are bent inward.

[0075] exist Figure 8 In the specific embodiment shown, the antenna body 133 employs an interleaved series-fed microstrip patch antenna array, meaning that multiple patches 1332 are vertically distributed on both sides of the transmission line 1331, while the patches 1332 on both sides are interleaved, with an operating frequency band of 0.4-8 GHz. Different lengths of the patches 1332 correspond to different frequencies; the lower the frequency, the longer the wavelength, and the longer the corresponding patch 1332. To increase the operating frequency band of the antenna body 1333 and achieve lower frequency operation, a longer patch 1332 is needed, which inevitably increases the overall product size. Therefore, to minimize the product size while still meeting the requirements for lower frequency operation, the ends of the longer patches 1332 are bent inwards, maintaining the same patch length and thus reducing the overall area of ​​the circuit board 132, thereby ensuring a relatively small product size.

[0076] It is understood that the figure is only one example. In some other embodiments, the antenna body 133 may also adopt other types and operating frequency bands of microstrip patch antenna arrays. Accordingly, at least some of the ends of the patches 1332 may also be bent inward to increase the operating frequency band while meeting the miniaturization requirements of the antenna 100.

[0077] According to another aspect of the embodiments of this application, a drone detection system is provided, for details please refer to again. Figure 7The UAV detection system 500 includes a signal processing device 300 and an antenna 100 provided in the above embodiment. The signal processing device 300 can be a computer (e.g., an industrial computer), a handheld terminal (e.g., a tablet computer, a mobile phone), or a controller specifically for UAV detection. The signal processing device 300 and the antenna board 130 in the antenna 100 are connected by a wiring harness 200 to achieve signal transmission.

[0078] The UAV detection system 500 provided in this application embodiment, by adopting the antenna 100 with good rainproof performance in the above embodiment, can ensure the stability and reliability of the antenna 100 when conducting UAV detection operations in rainy weather.
