Abstract
Description
Technical Field
[0001] This utility model relates to the field of direction finding antenna technology, and in particular to a backpack-type direction finding antenna assembly. Background Technology
[0002] Backpack-mounted direction finding antennas are key components in radio direction finding equipment for receiving signals and determining their direction of origin. They are commonly used in outdoor mobile detection scenarios, making it convenient for operators to carry them to complex terrains to conduct direction finding operations.
[0003] Backpack-mounted direction-finding antenna assemblies often need to withstand the effects of harsh outdoor environments during operation, such as vehicle collisions, product drops, and vibrations and shocks during equipment operation. Current direction-finding antenna structures are not strong enough, and after being subjected to impacts and vibrations, problems such as antenna element displacement and loosening of connections are prone to occur, which will directly affect the direction-finding accuracy and may even cause the antenna to be scrapped in severe cases, thus failing to meet the usage requirements in harsh outdoor operating scenarios. Utility Model Content
[0004] The purpose of this invention is to address the problem that existing direction-finding antenna assemblies cannot meet the requirements for use in harsh outdoor operating environments, and to propose a backpack-type direction-finding antenna assembly.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A backpack-mounted direction-finding antenna assembly includes:
[0007] The mounting plate is disc-shaped;
[0008] An antenna assembly is disposed on the mounting plate and is detachably connected to the mounting plate;
[0009] The radome is a sleeve-shaped structure with one end closed. The other end of the radome, away from the closed end, is connected to the mounting plate. The radome is fitted over the outside of the antenna assembly to reduce the influence of external factors on the antenna assembly.
[0010] A support sleeve, one end of which is disposed at the other end of the mounting plate, the support sleeve being located away from the antenna assembly, and the support sleeve being detachably connected to the mounting plate;
[0011] A spring, one end of which is connected to the other end of the support sleeve, is located away from the antenna assembly and is used to reduce the impact of external forces.
[0012] A connecting plate is disposed at the other end of the spring, and the direction-finding antenna assembly is used to be mounted on a direction-finding vehicle or other equipment via the connecting plate.
[0013] In one feasible embodiment, the antenna assembly includes:
[0014] The mounting base is disc-shaped and has a central through hole; the mounting base is connected to the mounting disc.
[0015] A connector is disposed in the central through hole of the mounting base and is fixedly connected to the mounting base;
[0016] Multiple support columns are disposed on the mounting base and are arranged in a rectangular pattern around the connector. The support columns are detachably connected to the mounting base.
[0017] An antenna radiator is disposed on the top of the mounting base and is connected by multiple support columns. The antenna radiator is used for antenna direction finding.
[0018] One feasible solution also includes:
[0019] Multiple connecting parts are provided on the outside of the mounting plate and are arranged in a circular array along the central axis of the mounting plate. The support sleeve is detachably connected to the mounting plate through the multiple connecting parts.
[0020] In one feasible solution, the connecting portion includes:
[0021] A fastener is provided on the outside of the mounting plate and is fixedly connected to the mounting plate;
[0022] The fastener is located at one end of the support sleeve and is fastened to the fastener. The mounting plate and the support sleeve are detachably connected through the connecting part.
[0023] In one feasible solution, the connection between the radome and the mounting plate is filled with sealant and fitted with a sealing ring.
[0024] The beneficial effects of this utility model are as follows:
[0025] This invention uses a spring to buffer the connection between the support sleeve and the connecting plate. When the equipment is subjected to impact or drop, the spring can absorb most of the vibration and impact force, preventing the impact force from being directly transmitted to the antenna assembly and preventing displacement of the antenna elements or loosening of the connection. At the same time, the antenna cover provides an outer layer of protection for the antenna assembly, further isolating it from the influence of the external environment. Multiple connecting parts, together with the detachable connection between the support sleeve and the mounting plate, can also distribute stress while ensuring connection strength, further improving the overall structure's impact resistance and meeting the requirements for use in harsh outdoor operating environments.

[0039] Reference Figures 1 to 3In this embodiment, to address the limitation of existing direction-finding antenna assemblies in meeting the requirements of harsh outdoor operating environments, this utility model provides a backpack-type direction-finding antenna assembly. The assembly includes: an radome 1, a mounting plate 21, an antenna assembly 2, multiple connecting parts, a support sleeve 4, a spring 5, and a connecting plate 51. The mounting plate 21 is disc-shaped and serves to support and mount the antenna assembly 2. The antenna assembly 2 is mounted on the mounting plate 21 and is detachably connected to it for easy replacement and maintenance. The radome 1 is a sleeve-shaped structure with one end closed. The other end of the radome 1, away from the closed end, is connected to the mounting plate 21. The radome 1 is fitted over the antenna assembly 2 to reduce external influences on it. One end of the support sleeve 4 is located at the other end of the mounting plate 21, away from the antenna assembly 2. The support sleeve 4 is detachably connected to the mounting plate 21. Multiple connecting parts are disposed on the outside of the mounting plate 21, and are arranged in a circular array along the central axis of the mounting plate 21. The support sleeve 4 is detachably connected to the mounting plate 21 through multiple connecting parts to facilitate quick adaptation to outdoor direction finding requirements. One end of the spring 5 is connected to the other end of the support sleeve 4. The spring 5 is located away from the antenna assembly 2 and is used to reduce the impact of external impact forces. The connecting plate 51 is disposed at the other end of the spring 5, and the direction finding antenna assembly is used to be mounted on a direction finding vehicle or other equipment through the connecting plate 51. That is, in this embodiment, the spring 5 buffers the connection between the support sleeve 4 and the connecting plate 51. When the equipment is subjected to impact vibration from collision or drop, the spring 5 can absorb most of the vibration impact force, preventing the impact force from being directly transmitted to the antenna assembly 2 and preventing the antenna elements from shifting or the connection parts from loosening. Meanwhile, the antenna radome 1 provides an outer layer of protection for the antenna assembly 2, further isolating it from the influence of the external environment. The multiple connecting parts, together with the support sleeve 4 and the mounting plate 21, can be detached to ensure the connection strength while dispersing stress, further improving the overall structure's impact resistance and meeting the usage requirements in harsh outdoor operating scenarios.
[0040] Reference Figure 2 and Figure 3In this embodiment, the antenna assembly 2 includes: a mounting base 211, a connector 212, multiple support columns 22, and an antenna radiator 23. The mounting base 211 is disc-shaped and has a central through-hole (not shown in the figure). The mounting base 211 is connected to the mounting disk 21. The connector 212 is disposed within the central through-hole of the mounting base 211 and is fixedly connected to the mounting base 211 by bolts. Multiple support columns 22 are disposed on the mounting base 211 and are rectangularly distributed around the connector 212. The support columns 22 are detachably connected to the mounting base 211 by bolts. The antenna radiator 23 is disposed on the top of the mounting base 211 and is connected to the multiple support columns 22. The antenna radiator 23 is used for antenna direction finding. In this embodiment, multiple support columns 22 provide stable support for the antenna radiator 23, while separating the antenna radiator 23 from the mounting base 211, ensuring the working space of the antenna radiator 23, maintaining the stability of the direction finding signal reception, and all of them can be detached and connected, making it convenient to replace and maintain individual damaged parts.
[0041] Reference Figure 2 and Figure 3 As shown, multiple connecting parts are arranged in a circular array along the central axis of the mounting plate 21. These connecting parts allow for a detachable connection between the mounting plate 21 and the support sleeve 4. For ease of description, one connecting part is used as an example. Specifically, the connecting part includes a fastener 3 and a fastener connector 41. The fastener 3 is located on the outer side of the mounting plate 21 and is fixedly connected to it. The fastener connector 41 is located at one end of the support sleeve 4 and is fastened to the fastener 3. This allows operators to quickly disassemble and replace antenna components 2 of different specifications according to actual direction-finding requirements. After adjustment, the entire assembly can be installed via the connecting plate 51, and the operation can then commence.
[0042] In this embodiment, to ensure the waterproof sealing of the direction-finding antenna assembly, the direction-finding antenna assembly adopts a fully enclosed structural design. The connection between the radome 1 and the mounting plate 21 is filled with sealant and fitted with sealing rings. Preferably, the radome 1 is mainly made of fiberglass cloth and epoxy resin, and its production process involves impregnating the fiberglass cloth with epoxy resin layer by layer, resulting in good hydrophobicity and high chemical stability.
