[0029] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] refer to Figure 1 、 Figure 2 、 Figure 7-Figure 9 As shown, an embodiment of the present application provides a communication device, comprising a device body 1, an antenna module 2, a connection module 3, and a radio frequency cable 4. The antenna module 2 is reversibly connected to the device body 1 via the connection module 3. The radio frequency cable 4 includes an upper end 41, a coil portion 42, and a lower end 43, which are connected in sequence. The upper end 41 is electrically connected to the connection end of the device body 1, and the lower end 43 is electrically connected to the connection end of the antenna module 2. The coil portion 42 includes a first cable 421 having a length that enables electrical connection between the upper end 41 and the lower end 43. The coil portion 42 also includes a second cable 422, and the upper end 41, the first cable 421, the second cable 422, and the lower end 43 are connected in sequence. The connection module 3 includes a positioning post 32 and a positioning and rotating assembly 31. The second cable 422 is wound around the positioning post 32. The positioning post 32 is fixedly connected to the positioning and rotating assembly 31. The antenna module 2 is reversibly connected to the device body 1 via the positioning and rotating assembly 31.

[0031] Among them, it can include multiple RF cables 4, or only one RF cable 4, which are all within the protection range. The device body 1 can generate RF signals and transmit them through the antenna module 2. The device body 1 includes, for example, a baseband board and a RF board. The antenna module 2 can include one or more antennas. The antenna module 2 can be flipped relative to the device body 1 through the connection module 3. For example, when not working, the antenna module 2 can be in Figure 1 In the state shown, if work is required, the antenna module 2 can be flipped 90 degrees or 180 degrees.

[0032] The RF cable 4 is used to electrically connect the antenna module 2 to the device body 1. In this embodiment, the RF cable 4, consisting of the upper end 41, the first cable 421, and the lower end 43, effectively enables an electrical connection between the antenna module 2 and the device body 1 in any state. However, when the antenna module 2 is flipped over, some tension may be applied to the RF cable 4 (especially at the bend).

[0033] In order to improve the reliability of the RF cable 4, this embodiment further adds a second cable 422, that is, the entire RF cable 4 is sequentially connected by the upper end 41, the first cable 421, the second cable 422, and the lower end 43, so that the length of the RF cable 4 can not only meet the basic requirements, but also have a redundant part (i.e., the second cable 422), thereby reducing the bending stress caused to the RF cable 4 during the flipping of the antenna module 2. Among them, the specific form of the second cable 422 is not specifically limited in this embodiment, as long as it is a cable with a certain length. The second cable 422 can be wrapped around the connection module 3, or it can be located in a specially provided accommodation area, as long as it does not affect the flipping of the antenna module 2.

[0034] In one embodiment, reference Figure 7 、 Figure 8 as well as Figure 9 The second cable 422 is wound at least once around the positioning post 32. In this embodiment, the RF cable 4 is wound one or more times, while still meeting the basic requirement of electrically connecting the antenna module 2 and the device body 1. The second cable 422 is wound around the connection module 3, providing support and guidance for the second cable 422, making it easier to follow the flipping direction of the antenna module 2 and improving reliability.

[0035] In one embodiment, reference Figure 5 In the specific implementation process of this embodiment, the positioning column 32 is installed on the device body 1; a limited area 321 is set on the positioning column 32, and the coil part 42 on the RF cable 4 is located in the limited area 321.

[0036] The limiting area 321 may be, for example, a groove, within which the coil portion 42 of the RF cable 4 is located. Alternatively, the limiting area 321 may include two protruding dividing bars, between which the coil portion 42 of the RF cable 4 is located. In this embodiment, placing the RF cable 4 in the limiting area 321 can constrain the RF cable 4 and prevent it from swinging when folded.

[0037] In one embodiment, reference Figure 5 and Figure 6 In the specific implementation process of this embodiment, a limiting groove 3211 is set in the limiting area 321, and the coil part 42 on the radio frequency cable 4 is embedded in the limiting groove 3211.

[0038] If multiple RF cables 4 are included, all RF cables 4 can be placed in one limiting groove 3211, or multiple limiting grooves 3211 can be provided, with each RF cable 4 placed in a corresponding limiting groove 3211. These are all within the scope of protection of this application.

[0039] In one embodiment, reference Figure 5 、 Figure 7 、 Figure 8 and Figure 9 In the specific implementation of this embodiment, the first cable 421 extends along the outer side of the positioning post 32 from the upper end 41 to the lower end 43. The second cable 422 begins at the bottom of the first cable 4121 and wraps around the positioning post 32 at least once. In other words, the RF cable 4 begins at the upper end 41 and wraps around the outer side of the positioning post 32 for at least one and a half turns.

[0040] pass Figure 5 、 Figure 7 and Figure 9 It can be seen that the RF cable 41 can be wound one and a half turns within the limiting groove 3211, namely, it includes a first cable 421 connected to the upper end portion 41 and a second cable 422 that is wound at least one turn around the connection module 3. In this way, when the antenna module 2 is in the initial state, due to the gravity of the antenna module 2 itself, the second cable 422 can be tightly wound together with the first cable 421 and set within the limiting groove 3211. However, when the antenna module 2 is flipped to the working state of 180 degrees, part of the second cable 422 of the coil portion 42 can leave the limiting groove 3211 to cooperate with the flipping of the antenna module 2. This can provide a certain deformation space for the RF cable 4 and avoid causing large bending stress on the bending part of the RF cable 4 when the antenna module 2 is flipped.

[0041] In other embodiments, the second cable 422 may be wound around the positioning post 32 twice or even more times starting from the bottom of the first cable 421 and then connected to the lower end portion 43 .

[0042] In one embodiment, reference Figure 5 and Figure 6 In the specific implementation process of this embodiment, the positioning rotation component 31 is set on the outer side wall of the equipment body 1.

[0043] The positioning and rotating assembly 31 includes a rotating member 311, a rotating shaft bracket 312, and a supporting member 313 (such as a screw). The rotating member 311 is rotatably connected to the rotating shaft bracket 321 via the supporting member 313. The antenna module 2 is fixedly connected to the rotating member 311; the rotating shaft bracket 312 is connected to the device body 1.

[0044] The support member 313 can be fixed to the rotating shaft bracket 312, and the rotating member 311 can be rotatably connected to the support member 313 and fixed to the antenna module 2. The support member 313 passes through the rotating shaft bracket 312 and the rotating member 311, and is fixed to the rotating shaft bracket 312 by fasteners 316 (such as screws). In this way, the antenna module 2 can be flipped and connected to the device body 1. For example, in the case of a frequency interferometer, the antenna module 2 is fixed to the chassis of the interferometer body via the rotating shaft bracket 312.

[0045] In one embodiment, reference Figure 5 and Figure 6 In the specific implementation process of this embodiment, the positioning rotation component 31 further includes an elastic member 315 . A blind hole 3111 is provided on the rotating member 311 , and the elastic member 315 is pressed into the blind hole 3111 .

[0046] Specifically, the elastic member 315 provided in this embodiment may be a spring lock pin, or may be other elastic locking members, which is not specifically limited here.

[0047] The rotating shaft bracket 312 is provided with a positioning groove 3121 for the elastic member 315 to spring into when the antenna module 2 is flipped to the set state.

[0048] The specific working process is as follows: when the antenna module 2 rotates around the support member 313, the elastic member 315 in the rotating member 311 also rotates accordingly. However, since the antenna module 2 has not yet been flipped to the set state (for example, the set state is to flip the antenna module 2 upward 180 degrees, at which point the communication device needs to start working), the hinge bracket 312 will resist the elastic member 315, and the elastic member 315 will not be able to pop outward. When the antenna module 2 is flipped to the set state, the elastic member 315 is opposite the positioning groove 3121. At this time, the elastic member 315 will be engaged with the positioning groove 3121 under the action of the elastic force, and the antenna module 2 is fixed to the device body 1. In addition, the end of the elastic member 315 that abuts the positioning groove 3121 can be spherical. When the communication device needs to stop working, it can be easily bent by hand, and the elastic member 315 can be pressed back into the blind hole 3111, and the antenna module 2 can be flipped back to the initial state, thereby improving the user experience.

[0049] It is understandable that the positions of the elastic member 315 and the positioning slot 3121 may also be interchanged, that is, the elastic member 315 and the blind hole 3111 are provided on the rotating shaft bracket 312 , and the positioning slot 3121 is provided on the rotating member 311 .

[0050] Furthermore, this embodiment provides two sets of positioning grooves 3121 for the antenna module 2 in its initial state and in the aforementioned set state (e.g., flipped 180°). Therefore, in both the initial state and the set state, the elastic member 315 cooperates with the positioning grooves 3121 to secure the antenna module 2 relative to the device body 1. This advantage is that the antenna module 2 can be securely fixed to the device body 1, whether during transportation of the communication device or during operation, preventing damage to the components within the antenna module 2.

[0051] In one embodiment, reference Figure 9 In the specific implementation process of this embodiment, a first seal 44 and a second seal 45 are provided on the outer side of the lower end portion 43 of the RF cable 4. The first seal 44 and the second seal 415 cooperate to form a groove 46 for accommodating the lower end portion 43 of the RF cable 4; the lower end portion 43 of the RF cable 4 is sealed between the first seal 44 and the second seal 45.

[0052] Furthermore, a protrusion 47 protruding toward the RF cable 4 is provided in the groove 46 .

[0053] A plurality of protrusions 47 are provided in a groove 46 for accommodating the radio frequency cable 4 formed by cooperation between the first sealing member 44 and the second sealing member 45 , so as to better prevent water droplets from entering the interior of the antenna module 2 .

[0054] In addition, a first seal 44 and a second seal 45 are provided on the outside of the lower end portion 43. Part or all of the first seal 44 and the second seal 45 can be embedded in the antenna module 2. The housing of the antenna module 2 is tightened with fasteners (such as machine screws) to compress the first seal 44 and the second seal 45, thereby improving the waterproof effect of the outlet of the RF cable 4.

[0055] In one embodiment, reference Figure 7 and Figure 8 In the specific implementation process of this embodiment, a sealing component 23 is provided on the outer side of the upper end portion 41 of the antenna module 2. The sealing component 23 includes a third sealing member 232 and a fourth sealing member 233. The upper end portion 41 of the RF cable 4 is sealed between the third sealing member 232 and the fourth sealing member 233.

[0056] Furthermore, the device body 1 may be provided with a notch. The sealing assembly 23 may also include a pressing block 231, which presses the third sealing member 232 and the fourth sealing member 233 into the notch, thereby enhancing the sealing effect. The third sealing member 232 and the fourth sealing member 233 may be pressed into the notch in whole or in part. The pressing block 231 may be partially located within the notch and partially located outside the notch.

[0057] Further, refer to Figure 7 and Figure 8 In the specific implementation of this embodiment, a baffle 234 is provided on the side of the sealing assembly 23 (e.g., the pressure block 231) facing the RF cable 4. The baffle 234 covers both ends of the RF cable 4 along the width direction of the RF cable 41. By completely covering the RF cable 4 within the corresponding limiting area 321, the swing of the RF cable 4 during flipping can be further limited. There can be multiple RF cables 4, and the baffle 234 can cover multiple RF cables 4. The width direction of the RF cable 4 is perpendicular to the extension direction of the RF cable 4.

[0058] refer to Figure 3 In the specific implementation process of this embodiment, the antenna module 2 includes, for example, a cover assembly 21 and an antenna plate assembly, and the antenna plate assembly is disposed inside the cover assembly 21 .

[0059] refer to Figure 3 and Figure 4 In the specific implementation of this embodiment, the cover plate assembly 21 includes a first cover plate 211 and a second cover plate 212. The second cover plate 212 is provided with a plurality of antenna brackets 2121. The antenna plate assembly includes a plurality of antenna plates 22, each of which is fixed to the antenna bracket 2121. The first cover plate 211 is fastened to the second cover plate 212 and covers the antenna plate assembly.

[0060] The first cover plate 211 is fastened and fixed on the second cover plate 212 and covers the antenna plate assembly, thereby effectively protecting the antenna plate assembly.

[0061] By arranging a plurality of antenna supports 2121 on the second cover plate 212 and fixing a plurality of antenna boards 22 on the antenna supports 2121 respectively, the firmness of the connection between the antenna board 22 and the second cover plate 212 is effectively increased.

[0062] In one embodiment, reference Figure 5 In the specific implementation process of this embodiment, the connection module 3 includes two positioning and rotating components 31 and a positioning column 32 arranged between the two positioning and rotating components 31, and the positioning column 32 is fixedly connected to the two positioning and rotating components 31.

[0063] By adopting a connecting module 3 consisting of two positioning rotating components 31 and a positioning column 32 arranged between the two positioning rotating components 31, not only the purpose of connecting the device body 1 and the antenna module 2 is achieved, but also the purpose of flipping the antenna module 2 on the device body 1 is achieved.

[0064] refer to Figure 5 In the specific implementation process of this embodiment, if the process conditions permit, the positioning column 32 and the rotating shaft bracket 312 can be set as an integrated structure, so that the positioning column 32 and the rotating shaft bracket 312 are more firmly connected.

[0065] refer to Figure 6 In the specific implementation process of this embodiment, the positioning rotation component 31 may further include a gasket 314, and a mounting groove (not shown in the figure) is provided on the side of the shaft bracket 312 away from the rotating member 311, and the gasket 314 is provided in the mounting groove (not shown in the figure).

[0066] By setting a mounting groove on the side of the shaft bracket 312 away from the rotating member 311 and embedding the gasket 314 in the mounting groove, in addition to waterproofing the screw hole, it can also prevent slipping and enhance structural stability.

[0067] refer to Figure 4 In the specific implementation process of this embodiment, a sealing ring 2122 can also be provided on the second cover plate 212 of the antenna module 2. The sealing ring 2122 is embedded in the second cover plate 212, and a boss corresponding to the sealing ring 2122 is provided on the first cover plate 211 (not shown in the figure), and the boss presses the sealing ring 2122.

[0068] In the specific implementation process of this embodiment, the first sealing member 44 , the second sealing member 45 , the third sealing member 232 , the fourth sealing member 233 and the sealing ring 2122 may be made of silicone material.

[0069] In one embodiment, all the above-mentioned structures of the communication device provided in the embodiment of the present application, such as the device body 1, the antenna module 2, the connection module 3 and the radio frequency cable 4, can be applied to the frequency jammer. In other words, the above-mentioned communication device can be a frequency jammer. When using the frequency jammer, the antenna module 2 is flipped upward 180° under the action of the connection module 3. At this time, the antenna module 2 is located above the device body 1 and is vertically arranged. In this way, not only the purpose of the integrated design of the device body 1 and the antenna module 2 is achieved, but also the purpose of facilitating the flipping of the antenna module 2 during use, facilitating portability, and eliminating the need to repeatedly disassemble and assemble the antenna after use is achieved.
