Description

Technical Field

[0001] This application relates to the field of jamming technology, and in particular to a portable frequency jammer and a wireless signal shielding system. Background Technology

[0002] Portable frequency jammers, especially trolley-type frequency jammers, can create garbled interference in the received message signals of communication tools through frequency scanning. This prevents the communication tools from detecting normal data transmitted from the base station, thus preventing them from establishing a connection with the base station and achieving the purpose of signal jamming. Communication tools exhibit phenomena such as searching for a network, no signal, or no service system, achieving the purpose of blocking communication signals within a certain spatial range. They can be applied to confidential locations, such as military training sites, confidential meeting venues, or examination venues, rendering mobile phones, various model remote controls, various wireless cheating devices, wireless microphones, cordless phones, walkie-talkies, etc., unable to function properly. Existing trolley-type frequency jammers typically consist of a jammer main unit and several jamming antennas. The jamming antennas and the jammer main unit are usually designed separately, with multiple jamming antenna mounting points on the jammer main unit. During use, each jamming antenna is screwed onto the jammer main unit individually. Summary of the Invention

[0003] The inventors of this application have discovered that conventional trolley-type frequency jammers employ a separate design, treating the jamming antenna as a separate accessory. This requires the installation of more than ten jamming antennas during use, followed by disassembly afterward. This frequent installation and disassembly of the jamming antennas makes carrying and using the jammer and its main unit extremely inconvenient, time-consuming, and labor-intensive. Furthermore, errors in antenna installation are highly likely. In situations such as countering drones, the need to install more than ten jamming antennas results in insufficient response time, severely impacting and restricting the jammer's usability. Moreover, the repeated installation and disassembly of the jamming antennas can easily damage components. Furthermore, because the position and angle of the fixed jamming antenna on the main unit are fixed and cannot be changed, the installation direction of the jamming antenna on the main unit cannot be adjusted, affecting the signal shielding effect of the jammer. In view of the above problems, this application is proposed to provide a portable frequency jammer, a trolley-type frequency jammer, and a wireless signal shielding system that overcomes or at least partially solves the above problems.

Detailed Implementation

[0105] Existing portable frequency jammers, especially the trolley-type ones, typically come with more than ten antennas. These antennas are usually screwed onto the main unit, requiring several turns of the screw to attach each one. The inventors creatively discovered that such trolley-type frequency jammers have numerous technical problems and can no longer meet the demands of today's efficient and timely responses. For example, screwing on more than ten antennas is very time-consuming and laborious, and it's easy to connect the wrong antenna. Furthermore, in situations requiring rapid response, such as jamming drones, this type of machine has a very slow response speed, failing to meet operational needs.

[0106] Through extensive analysis, research, experimentation, verification, and continuous development, the inventors have broken through the traditional technical architecture of existing trolley-type frequency jammers. They have creatively proposed integrating the antenna of the trolley-type frequency jammer into the module and connecting it to the main unit of the jammer in an integrated manner, such as, but not limited to, a movable connection. This eliminates the need for repeated antenna disassembly and assembly, saving time and effort, and providing a fast response time, among other benefits.

[0107] A trolley-type frequency jammer typically includes a moving mechanism, which in some embodiments may include casters mounted on one side of the bottom of the jammer's main unit and a retractable lever mounted on the side wall of the jammer's main unit on the same side as the casters. This allows the user to pull the lever and drag it across the ground when the trolley-type frequency jammer needs to be moved.

[0108] The following description mainly uses a trolley case-type frequency jammer as an example. However, it is understood that the innovative technical solutions described below can also be extended to other suitable types of portable frequency jammers, such as, but not limited to, backpack-type frequency jammers, hand-held case-type frequency jammers, etc. Specifically, this can be achieved by adding or removing the corresponding portable configuration.

[0109] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0110] Example 1

[0111] Embodiment 1 of this application provides a trolley box type frequency jammer (hereinafter referred to as jammer) 1, referring to Figure 16 and Figure 17As shown, it includes: a jammer host 200, at least one antenna assembly 100, and a movable connector; the jammer host 200 and the at least one antenna assembly 100 are movably connected through the movable connector, so that the antenna assembly 100 can move relative to the jammer host 200, and the antenna assembly 100 and the jammer host 200 can be fixed together.

[0112] The jammer host 200 is used to generate radio interference signals. The antenna assembly 100 is used to transmit the radio interference signals. Optionally, the antenna assembly 100 is also used to receive radio signals from a preset frequency band of a base station and transmit the received radio signals to the jammer host 200 for analysis and processing.

[0113] Since the antenna assembly 100 is movably connected to the jamming device host 200 via the movable connector, when the antenna is not needed, it can be moved to a closed state relative to the jamming device host 200 via the movable connector without disassembling the antenna assembly; when the antenna is needed, it can be moved to an extended state relative to the jamming device host 200 via the movable connector. Thus, the antenna assembly 100 and the jamming device host 200 are integrated into a single design, eliminating the need for repeated antenna disassembly and reassembly, making it very convenient to use.

[0114] As described above, through the movable connection of the movable connector, the antenna assembly 100 can switch between a closed state and an extended state relative to the jammer host 200.

[0115] When the antenna assembly 100 is in an deployed state relative to the jammer host 200, the antenna assembly 100 can transmit radio jamming signals to the external space and / or receive radio signals from the base station.

[0116] Antenna assembly 100 includes: at least one antenna connection component 10, at least one antenna body 11, and a support mechanism. The support mechanism carries the at least one antenna body 11. The at least one antenna body 11 is used to transmit radio interference signals. The antenna connection component 10 includes at least one signal transmission element.

[0117] The antenna body 11 is electrically connected to the functional module 203 in the jammer host 200 through the signal transmission element. The signal transmission element is used to transmit signals between the antenna body 11 and the functional module 203.

[0118] In this embodiment, the antenna assembly 100, as part of the trolley-type frequency jammer, is electrically connected to the antenna body 11 and the functional module 203 in the jammer host 200 via a signal transmission element. Signal transmission occurs between the antenna body 11 and the functional module 203. The antenna assembly 100 is fixed to the jammer host 200 via a movable connector and is movable relative to the jammer host 200, achieving integration of the antenna assembly and the jammer host. This makes the overall size of the trolley-type frequency jammer more compact and facilitates its miniaturization. The device also has a simpler and more aesthetically pleasing appearance, avoiding the inconvenience of carrying and using the existing technology that separates the antenna from the jammer host. Furthermore, it reduces the problem of component damage caused by repeated antenna disassembly and reassembly. Moreover, for example, in situations such as countering drones, since a large number of jamming antennas are not required, the trolley-type frequency jammer can respond quickly.

[0119] In one specific embodiment, the movable connector includes: at least one rotating connection mechanism 13 (see also...) Figures 4 to 6 The rotating connection mechanism 13 connects one side of the bearing mechanism to the housing 22 of the jammer host 200 (see also...). Figure 18 The antenna assembly 100 is hinged to one side so that it can flip relative to the jammer host 200 as the rotating connection mechanism 13 rotates.

[0120] Optionally, the antenna assembly 100 is disposed on one side of the jammer host 200 via a rotating connection mechanism 13.

[0121] In specific implementation, at least one antenna assembly 100 can be set at a corresponding position on the jammer host 200 according to the actual assembly and use requirements of the trolley-type frequency jammer 1. For example, the at least one antenna assembly 100 can be set on one side of the jammer host 200, or the at least one antenna assembly 100 can be set on both sides of the jammer host 200.

[0122] In one embodiment, as the rotating connection mechanism 13 rotates, the antenna assembly 100 can be flipped relative to the jammer host 200 at an angle ranging from 0 degrees to 180 degrees.

[0123] Reference Figure 16 As shown, when the angle of rotation of the antenna assembly 100 relative to the jamming host is 0 degrees, the antenna assembly 100 and the jamming host 200 are closed together. At this time, the antenna assembly 100 is in a non-working state (closed state).

[0124] Reference Figure 27As shown, when the antenna assembly 100 is rotated 180 degrees relative to the jamming host 200, at least the antenna body 11 of the antenna assembly 100 is located above the jamming host 200. At this time, the antenna assembly 100 is in a first deployed state (first working state) relative to the jamming host 200.

[0125] Since the antenna body 11 is higher than the jammer host 200, the antenna body 11 can transmit radio interference signals into the external space to work without damaging the components in the jammer host 200.

[0126] Reference Figure 28 As shown, when the antenna assembly 100 is flipped at an angle of 90 degrees relative to the jammer host 200, the antenna assembly 100 is perpendicular to the jammer host 200. At this time, the antenna assembly 100 is in the second deployed state (second working state).

[0127] When the space is limited by height, the trolley-type frequency jammer 1 can be changed from being placed vertically (rotated 180 degrees) to being placed horizontally (rotated 90 degrees). The antenna assembly 100 is perpendicular to the jammer host 200, and the antenna body 11 is still located above the jammer host 200. In this way, the antenna assembly 100 can also transmit radio interference signals to the outside space to work without damaging the components in the jammer host 200.

[0128] The aforementioned signal transmission components may be, for example, radio frequency cables, rotary joints with signal transmission functions, etc., and the embodiments of this application do not limit them.

[0129] When radio frequency (RF) cables are used as the signal transmission components, these RF cables are bendable and are connected between the antenna body and the functional module.

[0130] To clearly explain the structure of the above-mentioned trolley box-type frequency jammer 1, the internal structure of the antenna assembly 100 in the jammer will be explained first.

[0131] Reference Figure 3 , Figure 12 , Figure 17 As shown, the antenna assembly 100 includes a support mechanism for supporting the antenna body 11; a rotating connection mechanism 13 connects the support mechanism and the housing of the jammer host 200 respectively, and the antenna assembly 100 can rotate relative to the jammer host 200 as the rotating connection mechanism 13 rotates.

[0132] For example, but not limited to, the structure of the load-bearing mechanism can include two scenarios:

[0133] In one scenario, the supporting mechanism includes a first cover plate, and the antenna body 11 is disposed on one side or opposite sides of the first cover plate.

[0134] In another scenario, refer to Figure 3 As shown, the supporting mechanism includes: a first cover plate 14 and a second cover plate 15 that are interlocked, forming an accommodating cavity between the first cover plate 14 and the second cover plate 15; and one or more antenna bodies are detachably disposed in the accommodating cavity.

[0135] It is understood that the antenna assembly 100 is not limited to the two situations described above, and can also be other suitable structural designs. The core innovative idea of ​​this application is that the jammer host 200 and the jamming antenna are integrated into one design, and are not separate designs that do not require disassembly. This solves the adverse effects of installing a large number of jamming antennas, making the trolley-type frequency jammer faster in response and saving time and effort, among other advantages. Therefore, any trolley-type frequency jammer that adopts this core technical idea should fall within the protection scope of this application.

[0136] The shape of the first cover plate 14 can be selected according to actual needs, and the shape of the first cover plate 14 is not limited to... Figure 3 , Figures 7 to 14 The shape shown can be, for example, a rectangular block or other polygonal block, and the shape of the second cover plate 15 is also adapted to the first cover plate 14.

[0137] In one embodiment, refer to Figures 1-3 As shown, the antenna connection component 10 in the antenna assembly includes at least one radio frequency cable 101 (multiple radio frequency cables are shown in the figure, but the embodiments of this application do not limit the number of radio frequency cables included in a single antenna connection component 10).

[0138] In one embodiment, the lead-out of the RF cable 101 of the antenna connection component 10 is connected to the corresponding antenna body 11 by, for example, soldering. When the RF cable 101 is connected to the antenna body 11 of the antenna assembly 100, refer to... Figure 12 As shown, the jammer host 200 can be connected via RF cable 101 to achieve the integration of antenna assembly 100 and jammer host 200, and to enable the antenna body 11 to rotate at various preset angles relative to jammer host 200 to adapt to the jammer signal transmission requirements under different circumstances.

[0139] Specifically, it can be, by reference Figure 17 As shown, when the jammer host 200 is connected via the radio frequency cable 101, a connector (not shown in the figure) is also provided at the corresponding outlet position of the radio frequency cable 101, and a corresponding connection structure is provided at the corresponding position of the jammer host 200. The antenna assembly 100 is electrically connected to the jammer host 200 by connecting the connector to the corresponding connection structure of the jammer host 200.

[0140] The trolley-type frequency jammer 1 (hereinafter referred to as jammer 1) in this application embodiment can employ different frequency synthesis techniques to transmit signals of different frequencies. For example, it can be Software Defined Radio (SDR) technology, Direct Digital Frequency Synthesis (DDS) technology, or Voltage Controlled Oscillator (VOC) technology. Of course, other frequency synthesis techniques described in the prior art can also be used, and this application embodiment does not specifically limit this approach.

[0141] The inventors of this application discovered that, due to the high signal transmission power of the trolley-type frequency jammer 1, if an RF cable 101 is used to connect the jammer host 200 and the antenna body 11, the load capacity of the RF cable 101 needs to be considered. Therefore, when selecting the RF cable 101, it is necessary to consider both flexibility and structural strength while meeting the signal transmission power requirements. Thus, factors such as the wire diameter, material, hardness, and bending ability of the RF cable 101 need to be considered in the selection. Furthermore, since the antenna assembly 100 needs to be flipped relative to the jammer host 200 during the operation of the trolley-type frequency jammer 1, a corresponding structure needs to be designed to prevent the RF cable 101 from twisting or even breaking during the flipping process.

[0142] For the reasons stated above, in this embodiment of the application, reference is made to Figure 1 , Figure 2 and Figure 17 As shown, the radio frequency cable 101 is located beside the rotating connection mechanism 13. The radio frequency cable 101 may include at least one bendable segment 1011 and a first straight segment 1012 and a second straight segment 1013 respectively connected to both ends of the bendable segment 1011.

[0143] The first straight segment 1012 is electrically connected to the antenna body 11, and the second straight segment 1013 is electrically connected to the functional module 203 in the jammer host.

[0144] Specifically, the first straight line segment 1012 and the second straight line segment 1013 can rotate relative to each other around a preset first rotation axis. During the relative rotation, the extensions of the first straight line segment 1012 and the second straight line segment 1013 intersect on the first rotation axis and remain perpendicular to the first rotation axis.

[0145] The radio frequency cable 101 can be bent to different degrees as the rotating connection mechanism 13 rotates, and the rotating connection mechanism 13 itself has a second rotation axis.

[0146] The first rotation axis and the second rotation axis mentioned above can have the following two relationships:

[0147] 1. The first rotation axis and the second rotation axis are the same rotation axis. During the relative rotation of the first straight line segment 1012 and the second straight line segment 1013, the extension line of the first straight line segment 1012 and the extension line of the second straight line segment 1013 intersect on the second rotation axis, and the first straight line segment 1012 and the second straight line segment 1013 are respectively perpendicular to the second rotation axis.

[0148] 2. The first rotation axis and the second rotation axis are two different rotation axes. During the relative rotation of the first straight line segment 1012 and the second straight line segment 1013, the extension line of the first straight line segment 1012 and the extension line of the second straight line segment 1013 intersect at a point and this intersection point is adjacent to the second rotation axis. The first straight line segment 1012 and the second straight line segment 1013 are respectively perpendicular to the second rotation axis.

[0149] When the RF cable is flipped so that the first straight segment 1012 and the second straight segment 1013 are perpendicular to each other, the bendable segment is in the shape of a C-shaped arc, which can prevent the RF cable 101 from breaking during multiple folding processes.

[0150] When the RF cable 101 is flipped so that the first straight segment 1012 and the second straight segment 1013 are horizontal, the bendable segment is in a nearly straight state. This design can avoid deformation of the RF cable 101 during the flipping process and make the appearance of multiple RF cables 101 look more concise.

[0151] Reference Figures 3-6 , Figure 12 , Figure 14 , Figure 16 and Figure 17 As shown, the antenna assembly 100 is connected to the jammer host 200 via a rotating connection mechanism 13. The rotating connection mechanism 13 connects the first cover plate 14 and the housing 22 of the jammer host 200 respectively, so that the first cover plate 14 rotates relative to the housing 22 of the jammer host 200 around the second rotation axis.

[0152] To facilitate relative rotation between the antenna assembly 100 and the jamming host 200, a rotational connecting mechanism 13 can be provided on each of the left and right sides of the first cover plate 14. The first cover plate 14 and the housing 22 of the jamming host 200 are connected by two rotational connecting mechanisms 13. This not only makes the relative rotation between the antenna assembly 100 and the jamming host 200 smoother, but also ensures a stable connection between them. However, in some embodiments, the rotational connecting mechanism 13 can be one, three, or other variations.

[0153] Reference Figure 4 , Figure 5 and Figure 17 As shown, the rotating connection mechanism 13 may include: a rotating shaft block 131, a rotating shaft bracket 132, and a support screw 133; the support screw 133 passes through the rotating shaft bracket 132 and the rotating shaft block 131, and is fixed to the rotating shaft bracket 132 by a nut 134 to form the aforementioned second rotating axis.

[0154] The pivot block 131 is rotatably mounted in the pivot bracket 132 with the support screw 133 as the pivot.

[0155] The rotating bracket 132 is connected to the housing 22 of the jammer host 200; the rotating block 131 is provided with an extension, which is connected to the first cover plate 14.

[0156] In the above embodiment, the second rotation axis is the central axis of the support screw 133. When the antenna assembly 100 rotates around the central axis of the support screw 133, the first straight segment 1012 and the second straight segment 1013 of the radio frequency cable 101 will also rotate relative to each other around the central axis of the support screw 133. During the relative rotation, the extension lines of the first straight segment 1012 and the second straight segment 1013 intersect the central axis of the support screw 133 and remain perpendicular to the central axis of the support screw 133.

[0157] The aforementioned support mechanism can rotate relative to the housing of the jammer host 200 around the second rotation axis (that is, the central axis of the support screw). The radio frequency cable 101 is located beside the rotating connection mechanism 13, and the radio frequency cable 101 flips around the same second rotation axis as the rotating connection mechanism 13.

[0158] When the radio frequency cable 101 is flipped so that the first straight segment 1012 and the second straight segment 1013 are perpendicular to each other, the bendable segment 1011 can be in the shape of a C-shaped arc.

[0159] Since the extensions of the first straight segment 1012 and the second straight segment 1013 intersect on the rotation axis and remain perpendicular to the first or second rotation axis, the pulling on the RF cable 101 can be reduced when the RF cable 101 is flipped, the deformation of the RF cable 101 during the flipping process is smaller, and the twisting phenomenon of the RF cable 101 is reduced.

[0160] For example, when the radio frequency cable 101 is flipped so that the first straight segment 1012 and the second straight segment 1013 are horizontal, the bendable segment 1011 can be in a straight or nearly straight state. During the flipping process of the antenna assembly 100 relative to the jamming host 200, the rotation angle of the antenna assembly 100 relative to the jamming host 200 can increase from 0° to 180°. During the flipping process of the antenna assembly, the angle between the first straight segment 1012 and the second straight segment 1013 will increase from -90° to +90°. During the flipping process of the antenna assembly 100, the extension degree of the bendable segment 1011 connecting the first straight segment 1012 and the second straight segment 1013 changes from small to large and then from large to small. When the rotation angle of the antenna assembly 100 relative to the jamming host 200 reaches 90°, the angle between the first straight segment 1012 and the second straight segment 1013 reaches 180°, that is, when the first straight segment 1012 and the second straight segment 1013 are in a horizontal state, the extension degree of the bendable segment 1011 reaches its maximum. At this time, the bendable segment 1011 can be in a straight or nearly straight state.

[0161] In one embodiment, refer to Figures 1-3 , Figure 17 As shown, the antenna connection component 10 also includes:

[0162] A first cable restraint device 12 is disposed on the first straight segment 1012 of the radio frequency cable 101;

[0163] Accordingly, the jammer host 200 includes a second cable restraint device 25. The first cable restraint device 12 is provided on the first straight segment 1012 of the radio frequency cable 101, and the second cable restraint device 25 is provided on the second straight segment 1013.

[0164] The first cable restraint device 12 has at least one groove inside that is adapted to the radio frequency cable 101;

[0165] The at least one radio frequency cable 101 is wrapped in the at least one groove.

[0166] In this embodiment, the RF cable 101 is wrapped within the groove of the first cable constraint device 12, thereby constraining the first straight segment 1012 and the second straight segment 1013 of the RF cable 101. This prevents the RF cable 101 from swinging left and right during the flipping process, reduces the degree of twisting of the RF cable 101, and avoids or reduces the phenomenon of inconsistent lengths of the RF cable 101 during the flipping process. At the same time, it also ensures that the extension lines of the first straight segment 1012 and the second straight segment 1013 of the antenna connection component 10 intersect on the rotation axis and remain perpendicular to the rotation axis during relative rotation.

[0167] In this embodiment of the application, if the center distance between two adjacent RF cables 101 is too small, in order to avoid the RF cables 101 from swinging left and right and interfering with each other during the flipping process, the center distance between two adjacent RF cables 101 can be set to be no less than 13mm. Correspondingly, the multiple grooves on the first cable constraint device 12 should also meet the corresponding center distance requirements because they are adapted to the shape of the RF cables 101.

[0168] In one embodiment, refer to Figure 1 and Figure 2 As shown, the first cable restraint device 12 includes: a first restraint part 121 and a second restraint part 122;

[0169] The first constraint part 121 and the second constraint part 122 are pressed together and connected, and the first constraint part 121 and the second constraint part 122 are respectively provided with grooves that are adapted to the radio frequency cable 101.

[0170] The first constraint part 121 and the second constraint part 122 can be made of waterproof materials to meet the waterproof requirements of the jammer 1. For example, various elastic waterproof materials such as silicone and rubber can be used.

[0171] Reference Figure 1 and Figure 2 As shown, the first cable restraint device 12 includes: a first restraint part 121 and a second restraint part 122 disposed opposite to each other; the first restraint part 121 and the second restraint part 122 are pressed together relative to each other, and the first restraint part 121 and the second restraint part 122 are respectively provided with a first groove 1211 and a second groove 1221 adapted to the radio frequency cable 101.

[0172] As a specific implementation method of this application, refer to Figure 3 , Figures 7 to 14 As shown, the antenna assembly 100 may include a first cover plate 14 and a second cover plate 15, wherein the second cover plate 15 is used to fasten to the first cover plate 14. For example, the second cover plate 15 is tightened onto the first cover plate 14 by means of a machine screw 17. The second cover plate 15 can press the first constraint part 121 and the second constraint part 122, thereby achieving the purpose of waterproofing the outlet of the radio frequency cable 101.

[0173] In one specific embodiment, the first constraint part 121 and the second constraint part 122 are threadedly connected to the first cover plate 14. For example, at least one first fixing hole 1214 and at least one fixing hole 1225 are respectively provided at corresponding positions of the first constraint part 121 and the second constraint part 122. At least one first internal threaded post 146 is provided at a corresponding position of the first cover plate 14, and at least one second internal threaded post 152 is provided at a corresponding position of the second cover plate 15. A machine screw passes through the second internal threaded post 152, the first fixing hole 1214 and the second fixing hole 1225, and is screwed to the first internal threaded post 146, thereby firmly fixing the first constraint part 121 and the second constraint part 122 between the first cover plate 14 and the second cover plate 15, thus ensuring the structural stability of the cooperation between the first constraint part 121 and the second constraint part 122.

[0174] In this embodiment of the application, the first constraint part 121 and the second constraint part 122 of the first cable constraint device 12 may be threadedly connected to the first cover plate 14 or the second cover plate 15. The above structure is only an example, and this embodiment of the application is not limited to the fixing method of using threaded connection.

[0175] In one specific embodiment of this application, the first cover plate 14 may also be provided with a plurality of antenna supports 142, and a plurality of antenna bodies 11 are respectively disposed on the corresponding antenna supports 142. RF cables 101 are electrically connected to the corresponding antenna bodies 11. When the second cover plate 15 is fastened and fixed to the first cover plate 14, the second cover plate 15 can cover all the antenna bodies 11 disposed on the antenna supports 142. In this embodiment, the height of the plurality of antenna supports 142 can be set according to actual conditions. Since the frequency range and size of different antenna bodies 11 may be different, the height of the plurality of antenna supports 142 may also be different, and the number of antenna supports 142 fixing different antenna bodies 11 may also be different.

[0176] In one specific embodiment, to ensure the waterproof effect of the first cable restraint device 12, refer to Figure 1 and Figure 2 As shown, the inner walls of the first groove 1211 and the second groove 1221 of the first constraint portion 121 and / or the second constraint portion 122 are further provided with at least one first horizontal strip-shaped protrusion 1212 and / or at least one second horizontal strip-shaped protrusion 1222. By providing the first horizontal strip-shaped protrusion 1212 and / or the second horizontal strip-shaped protrusion 1222, water droplets or water vapor can be better prevented from entering the interior of the antenna assembly 100.

[0177] In one specific embodiment, the first cover plate 14 and the second cover plate 15 are respectively provided with grooves for accommodating the first constraint part 121 and the second constraint part 122, so that when the first cover plate 14 and the second cover plate 15 are fastened together, the first constraint part 121 and the second constraint part 122 press against each other, and tightly wrap the first straight segment 1012 of the radio frequency cable 101 through the first groove 1211 and the second groove 1221.

[0178] In one embodiment, the number and connection relationship of the antenna body 11 and antenna connecting component 10 of the antenna assembly 100 can be flexibly set according to the usage scenario. Each radio frequency cable 101 of the antenna connecting component 10 can be connected to one antenna body 11, or multiple radio frequency cables 101 can be connected to the same antenna body 11, or some of the multiple radio frequency cables are connected one-to-one with the antenna body 11, and other radio frequency cables are connected to the antenna body 11 in a one-to-many relationship. This application embodiment does not limit this.

[0179] The RF cable 101 of the antenna connection component 10 is connected to the lead-out position of the antenna body, and may also be provided with a connector (not shown in the figure). The RF cable 101 and the antenna body 11 are connected by connecting the connector of the RF cable 101 to the connector of the antenna body 11; or, the lead-out of the RF cable 101 of the antenna connection component 10 is connected to the corresponding antenna body 11 by soldering.

[0180] As described above, in this embodiment of the application, the antenna body 11 is disposed in a cavity formed between the first cover plate 14 and the second cover plate 15. Specifically, the antenna body 11 may be disposed on the first cover plate 14 or on the second cover plate 15. When there are multiple antenna bodies 11, the different antenna bodies 11 are arranged at different heights.

[0181] When there are multiple antenna bodies 11, the frequency bands of the radio interference signals emitted by different antenna bodies 11 are different from each other. For example, the antenna body 11 is a microstrip antenna or a circuit board panel antenna.

[0182] Furthermore, the antenna body 11 may include a plurality of transmitting antennas and at least one receiving antenna. The functional module 203 is used to generate radio interference signals in multiple frequency bands and transmit them through the plurality of transmitting antennas. The at least one receiving antenna is used to receive radio signals in a preset frequency band and transmit them to the functional module 203 for analysis and processing through a signal transmission element (e.g., radio frequency cable 101).

[0183] If the antenna assembly contains multiple sets of antenna connecting parts 10, the spacing between adjacent antenna connecting parts 10 can be reasonably configured according to the shape and size of the connected antenna body.

[0184] In an optional embodiment, the inventors of this application discovered that, referring to Figure 22 and Figure 23 As shown, a winding post 30 can also be set at the position of the bendable section 1011 of the corresponding RF cable 101, and multiple winding slots 301 can be set on the winding post 30, so that the bendable section 1011 of each RF cable 101 corresponds to a winding slot 301. However, in this design, the rotation center of the RF cable 101 cannot coincide with the center line of the winding post 30, that is, the rotation center and the center of the winding post 30 are not on the same axis. During the flipping process of the antenna assembly 100, the length of the RF cable 101 is inconsistent at different angles, which can easily lead to a small bending radius and unsmooth bending. During the flipping process, the RF cable 101 may also jump out of the winding slot due to force and pulling.

[0185] Therefore, in the design of the trolley-type frequency jammer 1, the arrangement of multiple antenna connection components 10 side by side will occupy a large amount of space. Since the pivot block 131 is located on the side of the antenna assembly 100, if the RF cable 101 is connected by a hidden wiring method, it may aggravate the twisting and bending of the RF cable 101 during the flipping process, which may easily lead to the breakage of the RF cable 101. Therefore, it is necessary to consider how to save space or how to reduce the twisting and bending of the RF cable in the design.

[0186] In one embodiment, refer to Figure 3 , Figures 7 to 14 As shown, the one or more antenna bodies 11 are detachably mounted on the first cover plate 14; the first cover plate 14 is used to be rotatably connected to the jammer host 200 when the antenna assembly 100 is assembled on the jammer 1.

[0187] Reference Figures 1-14 As shown, in order to facilitate the relative rotation between the antenna assembly 100 and the jammer host 200, a rotating connection mechanism 13 can be provided on the left and right sides of the first cover plate 14 respectively. The first cover plate 14 and the housing 22 of the jammer host 200 are connected by the two rotating connection mechanisms 13. This not only makes the relative rotation between the antenna assembly 100 and the jammer host 200 smoother, but also ensures a stable connection between the antenna assembly 100 and the jammer host 200.

[0188] In one specific embodiment, refer to Figure 4 , Figure 5 and Figure 17As shown, the rotating connection mechanism 13 may include: a rotating shaft block 131, a rotating shaft bracket 132, and a support screw 133; the support screw 133 passes through the rotating shaft bracket 132 and the rotating shaft block 131, and is fixed to the rotating shaft bracket 132 by a nut 134 to form the rotating axis;

[0189] The rotating shaft block 131 is rotatably mounted in the rotating shaft bracket 132 with the support screw 133 as the axis (i.e., the second rotation axis);

[0190] The rotating bracket 132 is connected to the housing 22 of the jammer host 200; the rotating block 131 is provided with an extension, which is connected to the first cover plate 14.

[0191] In the above embodiment, the second rotation axis is the central axis of the support screw 133. When the antenna assembly 100 rotates around the central axis of the support screw 133, the first straight segment 1012 and the second straight segment 101 of the radio frequency cable 101 will also rotate relative to each other around the central axis of the support screw 133. During the relative rotation, the extension lines of the first straight segment 1012 and the second straight segment 1013 intersect the central axis of the support screw 133 and remain perpendicular to the central axis of the support screw 133.

[0192] In this embodiment, the pivot block 131 can be connected to the top of the first cover plate 14, the support screw 133 passes through the pivot bracket 132 and the pivot block 131, and the support screw 133 is fixed on the pivot bracket 132 by the nut 134, thereby realizing the rotatable connection of the antenna assembly 100 to the jammer host 200.

[0193] In one specific embodiment, refer to Figures 6 to 8 As shown, the rotating shaft block is also provided with at least one positioning hole 1313;

[0194] At least one protrusion 145 is provided on the edge of the first cover plate 14 at the position corresponding to the positioning hole 1313, and the protrusion 145 is inserted into the positioning hole 1313.

[0195] Reference Figures 3-8As shown, the antenna assembly 100 is provided with two sets of rotating connection mechanisms 13. Each set of rotating connection mechanisms 13 has two positioning holes 1313 on its rotating shaft block 131. The first cover plate 14 has two protrusions 145 respectively corresponding to the positions of the two rotating connection mechanisms 13. When the first cover plate 14 is connected to the rotating shaft block 131, by aligning each protrusion 145 with each positioning hole 1313 on the rotating shaft block 131, the positions of the first cover plate 14 and the rotating shaft block 131 can be aligned, thereby quickly completing the assembly of the first cover plate 14 and the rotating shaft block 131. Furthermore, through the cooperation of the positioning holes 1313 and the protrusions 145, the structural relationship between the first cover plate 14 and the rotating shaft block 131 can be made more stable and reliable, enhancing the structural strength of the connection between the rotating shaft block 131 and the first cover plate 14.

[0196] In the embodiments of this application, reference is made to Figure 5 As shown, a mounting groove 1322 can be provided on the back of the rotating shaft bracket 132 of the rotating connection mechanism 13. A pad 19 is placed in the mounting groove 1322. When the rotating shaft bracket 132 is fixed to the housing 22 of the jamming device host 200 by fastening screws, the pad 19, in addition to waterproofing the threaded hole, also serves as an anti-slip agent, thereby enhancing structural stability. The material of the pad 19 can be selected according to actual needs, such as silicone or rubber, or other waterproof materials with good elasticity and hardness. No specific limitation is made here.

[0197] In one specific embodiment, refer to Figure 5 As shown, a pre-compressed disc-shaped spring 135 is provided between the end of the rotating shaft block 131 and the rotating shaft bracket 132; the disc-shaped spring 135 is sleeved on the support screw 133.

[0198] In this embodiment of the application, the disc-shaped spring 135 is also called a disc spring. The disc-shaped spring 135 can be disposed at one end of the rotating shaft block 131, or the disc-shaped spring 135 can be disposed at both ends of the rotating shaft block 131.

[0199] By setting a pre-compression disc spring 135, the clamping force provided by the disc spring provides a certain damping force during the rotation of the antenna assembly 100. This prevents the antenna assembly 100 from rotating too much and also prevents it from loosening and deviating from the predetermined position after rotating to it. The disc spring 135 can be made of a wear-resistant material, such as metal, including stainless steel. The elastic friction between the disc spring 135 and the rotating shaft block 131 and the rotating shaft support 132 reduces the wear of the rotating shaft block 131 and the rotating shaft support 132 during rotation, which helps to increase the service life of the antenna assembly.

[0200] In this embodiment of the application, in order to achieve the function of angle limiting when the antenna assembly 100 rotates around the support screw 133, refer to Figure 4 and Figure 5 As shown, the rotating connection mechanism 13 may further include a pin 136 and an elastic element 137. Correspondingly, the rotating shaft block 131 has at least one blind hole 1311, and the pin 136 and the elastic element 137 are pre-pressed into the blind hole 1311. One end of the pin 136 abuts against the elastic element 137, and the other end abuts against the side wall of the rotating shaft support 132 through the opening of the blind hole 1311. During the rotation of the rotating shaft block 131 from its initial position, since the elastic element 137 is in a pre-pressed state, under the action of force, the elastic element 137 presses against the pin 136, causing it to abut against the side wall of the rotating shaft support 132 during the rotation of the rotating shaft block 131. When the rotating shaft block 131 rotates to a predetermined angle (position), the force exerted by the elastic element 137 on the side wall of the rotating shaft support 132 can keep the rotating shaft block 131 stable in the predetermined position, preventing the antenna assembly 100 from loosening after rotating to the predetermined position.

[0201] In one specific embodiment, to further ensure the stability of the antenna assembly 100 when rotated to a predetermined position, refer to Figure 4 and Figure 5 As shown, the side wall of the rotating shaft bracket 132 has at least one positioning groove 1321 at a position corresponding to the rotation trajectory of the blind hole 1311. This allows the pin 136 in the blind hole 1311 to extend out of the blind hole 1311 and engage in the positioning groove 1321 under the pre-tightening force of the elastic member 137 when the rotating shaft block 131 rotates to a preset angle. When the antenna assembly 100 rotates around the support screw 133, the pin 136 in the rotating shaft block 131 rotates accordingly. When the rotating shaft block 131 rotates to a preset angle, i.e., when the antenna assembly 100 rotates to a preset position, the pin 136 engages in the positioning groove 1321 under the elastic force of the elastic member 137, fixing the antenna assembly 100 in the preset position (e.g., a position where the antenna assembly is rotated 180 degrees relative to the jamming device host), thereby further preventing the antenna assembly 100 from loosening after rotating to the predetermined position.

[0202] In one specific embodiment, the positioning slot 1321 can be provided at least in the following locations: at the positions corresponding to the blind hole 1311 when the antenna body 11 in the antenna assembly 100 is at 0° and 180° relative to the jamming host 200; the above arrangement allows the antenna body 11 to be fixed at positions at 0° and 180° relative to the jamming host 200 when it rotates relative to the jamming host 200. Of course, the position of the positioning slot 1321 can also be set according to actual needs. For example, it can be at the position corresponding to the blind hole 1311 when the antenna body 11 in the antenna assembly 100 is at 90° relative to the jamming host 200, so that when the antenna body 11 rotates relative to the jamming host 200, it can be fixed at a position at 90° relative to the jamming host 200. The embodiments of this application do not limit the position of the positioning slot 1321.

[0203] In this embodiment, the elastic element 137 can be a spring, and one end of the pin 136 is connected to the spring.

[0204] Optionally, the aforementioned rotating connection mechanism can also have other structural forms. For example, when designing the rotating connection mechanism of the antenna assembly 100, the inventor referred to... Figures 22 to 26 As shown, an attempt was made to design a rotating bracket 132 directly connected to the rotating shaft 131'. The rotating shaft 131' has a ball bearing receiving hole 1325, and a ball bearing 1324 is placed in this hole. The rotation tightness can be adjusted by regulating the degree to which the ball bearing 1324 is screwed into and out of the rotating bracket 132. Furthermore, two circular holes 1323 are provided on the rotating bracket 132 to accommodate the ball bearing, respectively limiting the rotational positions of the ball bearing at 0 degrees and 180 degrees, thereby enabling the antenna module to switch between 0-degree and 180-degree positions. However, in this design, the rotating bracket 132 itself is prone to deformation, and combined with the processing errors of the rotating bracket 132 and the ball bearing 1324, the antenna assembly 100 may not easily reach the preset rotational position. Additionally, the stroke of the ball bearing 1324 is too short and its elasticity is too stiff, potentially resulting in insufficient smoothness of the antenna assembly 100's rotation. In addition, the height of the 1324 ball needs to be adjusted each time, which makes assembly slightly inconvenient. Therefore, it can be selected according to actual needs.

[0205] In this embodiment, the inventors have constructed a rotating connection mechanism 13 consisting of a pivot block 131, a pivot bracket 132, and a support screw 133. The support screw 133 passes through the pivot bracket 132 and the pivot block 131 and is fixed to the pivot bracket 132 by a nut 134. Thus, the pivot block 131 rotates within the pivot bracket 132 with the support screw 133 as its axis, thereby adjusting the rotation angle of the antenna assembly 100. Furthermore, by providing a disc-shaped spring 135 at the end of the pivot block 131, the elastic deformation of the disc-shaped spring 135 achieves a damping effect. Simultaneously, in conjunction with the design of the pin 136, the elastic element 137, the blind hole 1311, and the positioning groove 1321, when the antenna assembly 100 rotates to a preset angle, the pin 136 automatically pops out under the action of the elastic element 137 and locks into the positioning groove 1321 of the pivot bracket 132. The assembly is simple and convenient, ensuring the stability of the antenna assembly 100 after it rotates to the preset position.

[0206] In this embodiment, to facilitate smoother and more secure engagement of the pin 136 within the positioning groove 1321 when the antenna assembly 100 rotates, and to make it easier for the pin 136 to pop out of the positioning groove 1321 when the antenna returns to its pre-flipped state after use, the structure of the end of the pin 136 and the structure of the positioning groove 1321 are adapted to each other. For example, the end of the pin 136 can be spherical, and correspondingly, the shape of the positioning groove 1321 can be a spherical groove; or, the end of the pin 136 can be cylindrical, and correspondingly, the shape of the positioning groove 1321 can be a cylindrical hole.

[0207] In this embodiment of the application, in order to achieve multiple angles of flipping and fixing of the antenna assembly 100, the positioning groove 1321 can be set to multiple, and the multiple positioning grooves 1321 can be distributed at positions corresponding to different angles of the rotation trajectory of the blind hole 1311.

[0208] In one specific embodiment, refer to Figure 5 As shown, the rotary connection mechanism 13 may also include a toggle switch 138;

[0209] The rotating shaft block 131 is also provided with an oblong switch hole 1312 along the rotation axis, and the pin 136 is provided with a mounting hole 1361 in the radial direction. One end of the toggle switch 138 is connected to the pin 136 through the mounting hole 1361, and the other end passes through the oblong switch hole 1312 and is slidably engaged in the oblong switch hole 1312. When it is necessary to rotate the antenna assembly 100 from the preset position to the initial position or to other possible positions, the toggle switch 138 can be toggled along the oblong switch hole 1312 to disengage the pin 136 connected to it from the positioning groove 1321 and return it to the blind hole 1311, facilitating the rotation of the antenna assembly 100 again.

[0210] It should be noted that in the above example, when the end of the pin 136 is spherical and the corresponding positioning groove 1321 is shaped like a spherical groove, since the positioning groove 1321 is a blind hole, when the pin 136 is engaged in the spherical groove 1321, the positioning groove 1321 will block the movement of the pin 136. The elastic force of the elastic element 137 acts on the inner wall of the positioning groove 1321, and the pin 136 will not pop out of the positioning groove 1321. When the antenna assembly is rotated again... When component 100 is in operation, the end of pin 136 moves along the inner wall of positioning groove 1321 and can slide out of positioning groove 1321. Therefore, the rotating connection mechanism 13 does not need to be equipped with the aforementioned toggle switch 138. Of course, in order to make rotating antenna assembly 100 easier, the aforementioned toggle switch 138 and the corresponding waist-shaped switch hole 1312 can also be provided. By toggling the toggle switch 138, the elastic element 137 contracts and drives pin 136 to move out of positioning groove 1321, making it convenient to rotate antenna assembly 100.

[0211] When the end of the pin 136 is cylindrical and the positioning groove 1321 is a cylindrical hole, the cylindrical hole of the positioning groove 1321 can be a through hole or a blind hole. When the pin 136 is engaged in the positioning groove 1321, the outer wall of the pin 136 will contact the inner wall of the cylindrical hole. Due to the obstruction of the cylindrical hole, the pin 136 cannot slide out of the positioning groove 1321. Therefore, in this case, it is not convenient to change the flip angle of the antenna assembly 100. Therefore, the rotating connection mechanism 13 can be equipped with the aforementioned toggle switch 138 and the corresponding waist. The oblong switch hole 1312 is used to connect the toggle switch 138 to the pin 136. The toggle switch 138 can slidably engage within the oblong switch hole 1312. When the antenna assembly 100 needs to be rotated, the toggle switch 138 is toggled, causing the elastic element 137 to retract and move the pin 136 out of the positioning groove 1321. Since the travel of the toggle switch 138 is limited by the length of the oblong switch hole 1312, the travel of the pin 136 is restricted by the travel of the toggle switch 138, thus ensuring that the travel range of the pin 136 is controllable. Furthermore, when the cylindrical hole is a through hole, the toggle switch 138 prevents the pin 136 from popping out of the positioning groove 1321 under the elastic force of the elastic element 137.

[0212] In the embodiments of this application, reference is made to Figure 3As shown, the jammer 1 can be equipped with two sets of rotating connection mechanisms 13. In this case, only one set of rotating connection mechanisms 13 needs to be equipped with a pin 136, an elastic element 137, a positioning groove 1321, and a toggle switch 138. By setting a toggle switch 138, the pin 136 can be slid out of the positioning groove 1321, thereby realizing the rotation of the antenna assembly 100 relative to the jammer host 200. Of course, when the jammer 1 is equipped with three or more sets of rotating connection mechanisms 13, the pin 136, elastic element 137, positioning groove 1321, and toggle switch 138 can also be set on only one set of rotating connection mechanisms 13. This application embodiment does not limit this.

[0213] In one embodiment, refer to Figure 5 As shown, the back of the rotating shaft bracket 132 of the rotating connection mechanism 13 is connected to the housing 22 of the jamming device host 200, and a mounting groove 1322 is provided at the connection position. A pad 19 is embedded in the mounting groove 1322. In addition to waterproofing the screw holes, the pad 19 also serves to prevent slippage, thereby enhancing the structural stability.

[0214] The material of the aforementioned pad 19 can be selected according to actual needs. For example, it can be silicone or rubber. Of course, other waterproof materials with good elasticity and strength can also be selected, without specific limitations.

[0215] In one embodiment, to fix the outlet position of the RF cable 101 and facilitate the connection between the RF cable 101 and the antenna body 11, refer to... Figure 3 As shown, a wire harness bracket 16 is also provided on the first cover plate 14 below the first cable restraint device 12; the wire harness bracket 16 is used to fix the lead-out end of the first straight segment 1012 of the radio frequency cable 101.

[0216] The aforementioned wire harness bracket 16 can be connected to the first cover plate 14, for example, but not limited to, by screws, such as, but not limited to, machine screws 17. Fixing the wire harness bracket 16 to the first cover plate 14 by machine screws 17 not only increases the connection's firmness but also facilitates adjusting the tightness of the RF cable 101 lead-out end as needed, and fine-tuning the length of the RF cable.

[0217] In one specific embodiment, refer to Figure 3 , Figures 7 to 11As shown, the wire harness bracket 16 includes a base 161 and a cover 162; the base 161 and the cover 162 are respectively provided with wire harness grooves 163 adapted to the radio frequency cable; the base 161 and the cover 162 are fastened together and are threaded together to press the lead end of the first straight segment 1012 of the radio frequency cable 101. Specifically, the base 161 may have a threaded hole, and the corresponding position of the first cover plate 14 may also have a threaded hole. The base 161 is connected to the first cover plate 14 by a machine screw 17, and then the base 161 and the cover 162 are fastened together. In order to ensure that the connection between the base 161 and the cover 162 is stable, threaded holes may also be provided at the corresponding positions of the base 161 and the cover 162, and the base 161 and the cover 162 may be fastened by a machine screw 17.

[0218] In one specific embodiment, refer to Figure 3 , Figures 7 to 11 As shown, the wire harness bracket 16 is connected to the first cover plate 14 by a machine screw 17. For example, the following connection method is adopted: screw holes are provided at corresponding positions of the base 161 and the first cover plate 14, and the base 161 and the first cover plate 14 are fastened by machine screws to fix the wire harness bracket 16 to the first cover plate.

[0219] In one embodiment, refer to Figure 7 , Figure 11 and Figure 13 As shown, the first cover plate 14 is also provided with a sealing ring mounting groove 143, and the sealing ring 18 is disposed in the sealing ring mounting groove 143.

[0220] The second cover plate 15 has a protrusion 151 at a position corresponding to the sealing ring 18. When the first cover plate 14 and the second cover plate 15 are engaged, the protrusion 151 presses against the sealing ring 18 to seal the antenna body 11 and the part of the antenna connecting component 10 that is electrically connected to the antenna body 11. By pressing the sealing ring 18 against the protrusion 151, a seal is achieved between the first cover plate 14 and the second cover plate 15, ensuring the sealing effect of the antenna body 11 and the radio frequency cable 101 of the antenna connecting component 10.

[0221] In one specific embodiment, refer to Figure 9 As shown, the sealing ring 18 and the sealing ring mounting groove 143 are provided with corresponding mounting grooves and mounting groove notches 1431 between the receiving groove where the first constraint part 121 and the second constraint part 122 are located and the wire harness bracket 16;

[0222] The bottom of the first constraint part 121 and the second constraint part 122 are respectively provided with a first extension part 1213 and a second extension part 1223; the first extension part 1213 and the second extension part 1223 extend into the notch 1431 to seal the mounting groove notch 1431.

[0223] In one specific embodiment, refer to Figures 7-10 As shown, the number of antenna connecting parts is at least two; correspondingly, the number of mounting slot notches 1431 should also be consistent with the number of antenna connecting parts.

[0224] In this embodiment, the first extension 1213 and the second extension 1223 are located at the end of the sealing ring 18. Thus, even if a very small amount of water droplets flow along the first constraint part 121 or the second constraint part 122 under the action of surface tension, they will still be blocked by the mutually pressed boss 151 and the sealing ring 18, and will not be able to enter the antenna assembly 100, thus ensuring the sealing effect of the antenna assembly 100.

[0225] At least two mounting groove notches 1431 are provided on the sealing ring 18 and the sealing ring mounting groove 143, and each notch corresponds to at least two receiving grooves. An extension platform 141 is also provided above the sealing ring mounting groove 143 between two adjacent mounting groove notches 1431.

[0226] By setting the extension stage 141, even if a small amount of water droplets enter the cavity of the antenna assembly 100 along the first constraint part 121 or the second constraint part 122, these small amounts of water droplets will fall onto the extension stage 141 and will not be able to enter the interior of the antenna assembly 100, thus enhancing the waterproof performance of the antenna assembly.

[0227] In one embodiment, refer to Figures 15-19 As shown, the housing 22 of the jammer 1 also has a housing notch 221, through which the second straight segment 1013 of the radio frequency cable 101 in the antenna assembly 100 passes and is electrically connected to the functional module inside the housing 22.

[0228] In this embodiment, by providing a housing notch 221 in the housing 22 of the jammer 1, the second straight segment 1013 of the radio frequency cable 101 in the antenna assembly 100 can pass through the housing notch 221 to achieve electrical connection with the relevant functional modules inside the housing 22. The connection method is simple. Furthermore, since a second cable constraint device 25 is provided on the second straight segment 1013, the second straight segment 1013 of the radio frequency cable 101 can be constrained, thereby better realizing the rotation of the antenna assembly 100 relative to the jammer host 200.

[0229] In one specific embodiment, refer to Figures 15-21As shown, the second cable restraint device 25 has a similar structure to the first cable restraint device 12, and also includes two interlocking parts: the first restraint part 121 and the second restraint part 122.

[0230] The first constraint part 121 and the second constraint part 122 of the second cable restraint device 25 are interlocked and disposed in the housing notch 221, and are interference-fitted with the housing notch 221. The interference fit between the first constraint part 121 and the second constraint part 122 and the housing notch 221 improves the sealing between the second cable restraint device 25 and the housing 22, preventing water droplets or moisture from entering the housing 22 of the jamming device host 1 through the housing notch 221, and better achieving the waterproof effect at the housing notch 221.

[0231] In one specific embodiment, refer to Figure 21 As shown, the second constraint part 122 also has a folded edge 1224 extending outward from the housing 22, and the folded edge 1224 is in contact with the outer surface of the housing 22.

[0232] In one specific embodiment, refer to Figures 15-21 As shown, the jammer 1 also includes: a pressure plate 23;

[0233] The folded edge 1224 of the second constraint part 122 is located between the pressure plate 23 and the outer surface of the housing 22. The pressure plate 23 presses the folded edge 1224 of the second constraint part 122 in the horizontal direction so that the folded edge 1224 of the second constraint part 122 fits against the outer surface of the housing 22.

[0234] Reference Figures 15-21 As shown, the second constraint part 122 has a folded edge 1224. When the second constraint part 122 is provided in the housing notch 221, the inner side of the folded edge 1224 fits against the outer surface of the housing 22. Screw holes can be provided at the corresponding positions of the folded edge 1224 of the second constraint part 122 and the housing 22, and the second constraint part 122 can be fixed to the housing 22 by a machine screw 17.

[0235] Furthermore, in order to better fix the second constraint part 122 to the housing 22, a pressure plate 23 can be provided on the outer side of the folded edge 1224. That is, the folded edge 1224 is located between the pressure plate 23 and the outer surface of the housing 22. The pressure plate 23 presses the folded edge 1224 of the second constraint part 122, so that the folded edge 1224 of the second constraint part 122 fits better against the outer surface of the housing 22. The pressure plate 23 is also provided with screw holes corresponding to the positions of the folded edge 1224 of the second constraint part 122 and the housing 22. The pressure plate 23, the second constraint part 122 and the housing 22 are fixed together by machine screws 17.

[0236] In this embodiment, the first constraint part 121 also has a folded edge (not shown in the figure) extending outward from the housing 22. The folded edge of the first constraint part 121 can also fit against the outer surface of the housing 22. Of course, the folded edge of the first constraint part 121 can also be disposed between the pressure plate 23 and the outer surface of the housing 22. The pressure plate 23 presses the folded edge of the first constraint part 121, thereby making the folded edge of the first constraint part 121 fit better against the outer surface of the housing 22.

[0237] In other embodiments, both the first constraint portion 121 and the second constraint portion 122 may have folded edges extending outward from the housing 22. The folded edges of the first constraint portion 121 and the second constraint portion 122 may be in contact with the outer surface of the housing 22. Furthermore, the folded edges of the first constraint portion 121 and the second constraint portion 122 may be disposed between the pressure plate 23 and the outer surface of the housing 22. The pressure plate 23 presses the folded edges of the first constraint portion 121 and the second constraint portion 122, thereby allowing the folded edges of the first constraint portion 121 and the second constraint portion 122 to better fit the outer surface of the housing 22.

[0238] In one specific embodiment, refer to Figures 15-21 As shown, the jamming device also includes: a pressure block 21;

[0239] The aforementioned pressure block 21 presses the first constraint part 121 and the second constraint part 122 in the height direction and is connected to the housing 22.

[0240] In this embodiment of the application, the distance between the pressure block 21 and the two sides of the housing notch 221 can be less than the thickness of the side wall of the second constraint part 122. Thus, when the pressure block 21 is pressed against the first constraint part 121 and the second constraint part 122 on the second straight segment 1013, the pressure block 21 is pressed into the housing notch 221, and the pressure block 21 and the second constraint part 122 are interference fit.

[0241] In this embodiment, the housing 22 of the jamming device host 200 may also be provided with a fixing plate 24 corresponding to the position of the pressure block 21. The fixing plate 24 is disposed inside the housing 22, and when the pressure block 21 presses against the first constraint part 121 and the second constraint part 122, the pressure block 21 is fixed to the fixing plate 24. For example, but not limited to, the fixing plate 24 may be provided with a threaded post, and the corresponding position of the pressure block 21 may be provided with a screw hole, and the pressure block 21 may be fixed to the fixing plate 24 by a machine screw 17.

[0242] The fixing plate 24 also serves to enhance the strength of the housing 22. The fixing plate 24, in conjunction with the functional module 203, creates a good wind-blocking effect.

[0243] Another possible implementation, considering the ease of wiring in the housing 22 of the trolley-type frequency jammer 1 and without compromising the waterproof structure of the housing 22 itself, a cable passage hole is made in the housing 22 at the position corresponding to the RF cable 101 of the antenna assembly 100. The RF cable 101 is then connected to the jammer by extending it through the cable passage hole. When the housing 22 is made of PE material, the opening process for the cable passage hole needs to be strictly controlled to avoid burrs. Furthermore, the error between the actual size of the cable passage hole and the design size must be controlled within a reasonable range. When routing the RF cable through the cable passage hole, a waterproof design is required at the location of the cable passage hole to effectively achieve waterproofing. Moreover, considering that the housing 22 of the trolley-type frequency jammer 1 also needs to be equipped with exhaust and ventilation structures, when opening the corresponding openings for these structures in the housing 22, efforts should be made to avoid reducing the overall strength of the housing 22. This is to prevent the entire wall of the housing 22 from being pulled along when the antenna assembly 100 is rotated, thus reducing the risk of breakage of the housing 22.

[0244] The design incorporates a housing notch 221 at the upper end of the jammer's housing 22. This notch 221 corresponds to the location of the second straight segment 1013 of the RF cable 101. To achieve waterproofing at the housing notch 221, a pressure block 21 is placed above the first constraint portion 121 after the first constraint portion 121 and the second constraint portion 122 on the second straight segment 1013 are positioned at the housing notch 221. The pressure block 21 presses down on the first constraint portion 121 and the second constraint portion 122, thus waterproofing the outlet of the second straight segment 1013 of the RF cable 101. Furthermore, to ensure waterproofing, the distance between the pressure block 21 and the two sides of the housing notch 221 can be less than the thickness of the sidewall of the second constraint portion 122, achieving an interference fit between the pressure block 21 and the second constraint portion 122. The single-sided interference between the pressure block 21 and the second constraint part 122 can be selected according to actual needs. For example, the single-sided interference between the pressure block 21 and the second constraint part 122 can be 0.6mm. Through the interference fit between the pressure block 21 and the second constraint part 122, the side of the second constraint part 122 is tightly pressed against the wall of the housing notch 221, achieving a seamless fit between the second constraint part 122 and the housing notch 221, thereby ensuring the waterproof effect at the housing notch 221. At the same time, in order to ensure the fixing effect of the pressure block 21, the pressure block 21 can be fixed to the jammer host 200 by a machine screw 17, thereby pressing and fixing the first constraint part 121 and the second constraint part 122. By connecting the housing 22 of the jammer through the pressure block 21, the overall structural strength of the housing 22 is improved. When rotating the antenna assembly 100, the risk of breakage of the entire housing 22 can be reduced, and the stability of the housing 22 of the trolley box type frequency jammer 1 is improved.

[0245] To further improve the waterproofing effect at the housing notch 221, the inner walls of the first groove 1211 and the second groove 1221 of the first constraint part 121 and the second constraint part 122 of the second cable restraint device 25 can also be provided with at least one first horizontal strip protrusion 1212 and at least one second horizontal strip protrusion 1222, respectively. By providing the first horizontal strip protrusion 1212 and the second horizontal strip protrusion 1222, water droplets can be better prevented from entering the interior of the jamming device host 200. Other specific structures of the second cable restraint device 25 can be referred to the description of the first cable restraint device 12 in the foregoing embodiment, and will not be described in detail here.

[0246] In one specific embodiment, refer to Figure 14 As shown, a first magnetic block 20 is also provided on the first cover plate 14 of the antenna assembly 100; correspondingly, a second magnetic block (not shown in the figure) that attracts the first magnetic block 20 is provided inside the housing 22 of the jammer.

[0247] By setting the first magnetic block 20 and the second magnetic block, when the antenna assembly 100 is in the initial position or in an unused state, it can be attracted to the housing 22 of the jammer host 200, thereby improving the stability of the antenna assembly 100 and the overall structure of the jammer.

[0248] The first magnetic block 20 and the second magnetic block can refer to substances that can directly or indirectly generate magnetism, or permanent magnets made of permanent magnet materials, or media that can be magnetically attracted, such as iron, nickel, or cobalt. Assuming that the first magnetic block 20 is a permanent magnet, then the second magnetic block can be a medium that can be magnetically attracted.

[0249] In one specific embodiment, refer to Figure 12 As shown, a buffer pad 144 is also provided on the outer surface of the first cover plate 14 facing the housing 22 of the jammer. When the antenna assembly 100 rotates from other positions back to the initial position, the buffer pad 144 can buffer the impact of the antenna assembly 100 on the jammer host 200, and avoid impact on the jammer host 200.

[0250] The material of the cushioning pad 144 includes, but is not limited to, various elastic materials, such as silicone and rubber.

[0251] Example 2

[0252] Figure 29 and Figure 30This application illustrates a trolley-type frequency jammer 1a in some other embodiments. The trolley-type frequency jammer 1a includes a jammer main unit 200a, an antenna assembly 100a, and a slide rail assembly 40' that slidably connects the antenna assembly 100a to the jammer main unit 200a. The jammer main unit 200a and the antenna assembly 100a are also communicatively connected via a signal transmission element. The antenna assembly 100a can be...
