Description

Technical Field

[0001] This utility model relates to the field of satellite communication technology, specifically to a mobile satellite communication antenna mounting structure and a mobile satellite communication system. Background Technology

[0002] With the rapid development of satellite communication technology, mobile satellite communication terminals are widely used in mobile communication, remote monitoring, and intelligent transportation. Traditional mobile satellite communication terminals typically use external antennas, directly installed on the exterior of the vehicle, such as the top or side. While this installation method facilitates signal reception, it presents several problems: First, external antennas are susceptible to external environmental factors such as wind resistance, rain and snow erosion, and mechanical impacts, leading to performance degradation or damage. Second, the antenna protrudes from the vehicle's surface, affecting its overall aesthetics and aerodynamic performance. Third, the installation process is complex, requiring modification after the vehicle leaves the factory, which can easily damage the vehicle's structure and increase costs and safety hazards.

[0003] In existing technologies, some solutions attempt to integrate the antenna inside the carrier, but these often face the problem of poor signal transmission. The surface material is usually metal or non-transparent composite material, which cannot effectively transmit satellite signals, resulting in poor communication quality. To solve this problem, some designs introduce dedicated radomes, but these radomes are mostly independent components that require additional fixing, making installation inconvenient. Furthermore, their poor sealing allows dust and moisture to easily enter the interior, affecting the stability and lifespan of the phased array antenna. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile satellite communication antenna installation structure and a mobile satellite communication system to solve at least one of the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A mobile satellite communication antenna mounting structure includes: an antenna body disposed at an opening in the roof of a vehicle;

[0007] The antenna body is equipped with an antenna cover on top, which is set inside the opening in the roof of the vehicle. The outer curvature of the antenna cover is consistent with and flush with the outer curvature of the roof of the vehicle.

[0008] Furthermore, the aforementioned radome includes a paper honeycomb composite material panel and a fiberglass cladding disposed on the outside of the paper honeycomb composite material panel; the outer curvature of the fiberglass cladding is consistent with and flush with the outer curvature of the vehicle roof.

[0009] Furthermore, the edge of the antenna body is connected to the roof of the vehicle via a connector, and a sealing ring is provided between the antenna body and the inner top wall of the roof of the vehicle.

[0010] Furthermore, the antenna body is equipped with a power interface and a radio frequency interface. The power interface is used to connect to the power supply wire of the vehicle that is pre-embedded in the roof of the vehicle at the factory. The radio frequency interface is used to process the satellite communication signals received by the antenna body and forward them to other radio frequency devices on the vehicle.

[0011] Furthermore, the aforementioned vehicle canopy can be the canopy of a car, truck, bus, tractor, ship, aircraft, or engineering equipment.

[0012] Furthermore, the aforementioned radome is bonded, snapped, or integrally formed with the roof of the vehicle.

[0013] A mobile satellite communication system includes: an antenna transmitting subarray and an antenna receiving subarray, both mounted on a vehicle via the aforementioned mobile satellite communication antenna mounting structure.

[0014] Furthermore, the aforementioned antenna transmitting subarray and antenna receiving subarray are arranged in two areas of the vehicle roof, or the antenna transmitting subarray and antenna receiving subarray are arranged in the same area of ​​the vehicle roof, and an electromagnetic isolation strip is provided between the antenna transmitting subarray and antenna receiving subarray.

[0015] Furthermore, the aforementioned antenna transmitting subarray and / or antenna receiving subarray are in the form of strips, which are disposed at the edge of the windshield of the vehicle.

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1:

[0027] like Figures 1 to 3 As shown, this embodiment provides a mobile satellite communication antenna installation structure, which includes: an antenna body 20 disposed at the opening of the vehicle roof 10, an antenna cover 21 disposed on the top of the antenna body 20, the antenna cover 21 can be connected to the antenna body 20 or separated from the antenna body 20, the antenna cover 21 is disposed in the opening of the vehicle roof 10 and connected to the vehicle roof 10, the outer side curvature of the antenna cover 21 is consistent with and flush with the outer side curvature of the vehicle roof 10, improving the overall aesthetics and aerodynamic performance of the vehicle.

[0028] In this embodiment, the vehicle canopy 10 is the canopy of a vehicle such as a car, truck, bus, tractor, ship, aircraft, or engineering equipment. An opening is pre-formed in the vehicle canopy 10 during manufacturing. A pre-set bracket is simultaneously formed on the inner wall of the vehicle canopy 10 near the edge of the opening. This pre-set bracket increases the thickness at the connection point with the antenna body 20, not only increasing the strength of the opening but also facilitating the installation of the connector.

[0029] Preferably, the opening of the vehicle roof 10 is a stepped hole. Specifically, the size of the opening on the outside of the vehicle roof 10 is larger than the size of the opening on the inside of the vehicle roof 10.

[0030] The antenna body 20 uses satellite communication frequencies to access the Tiantong satellite. The frequencies can be C, L, Ku, or Ka bands. The Tiantong satellite accesses the Internet through a satellite gateway station.

[0031] The top edge of the antenna body 20 is fixedly connected to a pre-set bracket of the carrier roof 10 via a connector. To ensure waterproofing, dustproofing, and sealing, a sealing ring 30 is placed between the top edge of the antenna body 20 and the pre-set bracket. The sealing ring 30 is deformed by the compressive force provided by the connector, thereby sealing the edge of the antenna body 20 and achieving waterproofing, dustproofing, and sealing. In this embodiment, the connector can be a bolt, pin, etc.

[0032] Preferably, the sealing ring 30 is provided with a through hole that mates with the connector to ensure the installation stability of the sealing ring 30.

[0033] The antenna body 20 is equipped with a power interface 22 and a radio frequency interface 23. The power interface 22 is used to connect to the power supply cable of the vehicle that is pre-embedded in the vehicle roof 10 at the factory. The radio frequency interface 23 is used to process the satellite communication signals received by the antenna body 20 and forward them to other radio frequency devices on the vehicle. The antenna body 20 may also be equipped with a network interface, USB interface, TYPE-C interface, etc., as needed.

[0034] The radome 21 includes a paper honeycomb composite material panel 211 and a fiberglass cladding 212. The fiberglass cladding 212 is fixed to the outside of the paper honeycomb composite material panel 211 by means of bonding or other methods. The shapes of the paper honeycomb composite material panel 211 and the fiberglass cladding 212 are matched. The paper honeycomb composite material is preferably aramid paper honeycomb material, which has the characteristics of being lightweight, high-strength, and having good thermal insulation performance. The paper honeycomb composite material panel 211 is inserted into the opening of the vehicle roof 10 from the outside and is fixedly connected to the vehicle roof 10 by means of bonding, snap-fitting, or integral molding. Obviously, the paper honeycomb composite material panel 211 can also be connected to the vehicle roof 10 by other non-removable methods to ensure that the paper honeycomb composite material panel 211 and the vehicle roof 10 are non-removable and cannot be modified, ensuring the consistency of the vehicle's outer shell during subsequent use. The outer curvature of the fiberglass cladding 212 is consistent with and flush with the outer curvature of the vehicle roof 10. The edge of the fiberglass cladding 212 is connected to the side wall of the opening of the vehicle roof 10 through adhesive or sealing material, so as to achieve a seamless connection between the fiberglass cladding 212 and the vehicle roof 10.

[0035] In this embodiment, the integrated molding method means that the carrier canopy 10, the paper honeycomb composite material plate 211, and the fiberglass cladding 212 are manufactured simultaneously in the same process, rather than installing the paper honeycomb composite material plate 211 and the fiberglass cladding 212 during the subsequent installation of the antenna body.

[0036] After the opening in the vehicle roof 10 is completed, it is sealed by a paper honeycomb composite material panel 211 and a fiberglass cladding 212. The presence of the paper honeycomb composite material panel 211 and the fiberglass cladding 212 is equivalent to reserving a wave-transparent zone in the vehicle roof 10, allowing satellite signals to pass through efficiently without affecting the overall structural strength and waterproof performance of the vehicle top.

[0037] Example 2:

[0038] This embodiment provides a mobile satellite communication system, including an antenna transmitting subarray and an antenna receiving subarray. When the antenna transmitting subarray and the antenna receiving subarray are integrated together, they can be directly installed on the vehicle using the mobile satellite communication antenna mounting structure of Embodiment 1. When the antenna transmitting subarray and the antenna receiving subarray are set up separately, the antenna transmitting subarray and the antenna receiving subarray are respectively installed on the vehicle using the mobile satellite communication antenna mounting structure of Embodiment 1.

[0039] Preferably, the antenna transmitting subarray and the antenna receiving subarray are arranged in two areas of the vehicle roof 10. The division of these areas is based on the principle that the electromagnetic isolation of the antenna transmitting subarray and the antenna receiving subarray is good and the degree of electromagnetic interference is small after they are arranged in two areas. Taking a car as an example, the antenna transmitting subarray and the antenna receiving subarray can be arranged at the edges of the front windshield and the rear windshield, respectively. In this case, the antenna transmitting subarray and the antenna receiving subarray are far apart and electromagnetic interference is not likely to occur. Alternatively, the antenna transmitting subarray and the antenna receiving subarray can be arranged in the same area of ​​the vehicle roof 10, close to each other. In this case, an electromagnetic isolation strip is provided between the antenna transmitting subarray and the antenna receiving subarray to provide electromagnetic isolation and reduce the impact of electromagnetic interference.

[0040] Preferably, the antenna transmitting subarray and / or antenna receiving subarray are both strip-shaped and are located at the edge of the vehicle's windshield. This avoids creating a larger blind spot for the vehicle and increases the number of antenna elements in each antenna subarray, thereby improving signal transmission quality.

[0041] Preferably, the antenna transmitting subarray and / or antenna receiving subarray are both arranged on a transparent dielectric substrate, which can be integrated with the shape of the car glass to achieve an appearance that is indistinguishable from existing car window glass.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
