Description

Technical Field

[0001] This invention relates to the field of portable satellite stations, and in particular to a manual / automatic azimuth and pitch angle drive adjustment device for portable satellite stations. Background Technology

[0002] Portable satellite stations, as mobile satellite communication terminals, offer advantages such as light weight, small size, and easy deployment, and are widely used in scenarios such as emergency communication, telemedicine, field operations, military communication, and natural disaster relief. During the use of portable satellite stations, the antenna needs to be precisely aligned with the target satellite; this is achieved by adjusting the antenna's azimuth and elevation angles. This is a crucial step in ensuring the quality of the communication link. Currently, the azimuth and elevation drive structures of existing portable satellite stations are typically independently set up and distributed, resulting in a less compact overall structure and hindering the miniaturization and weight reduction requirements of portable devices.

[0013] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to Figures 1 to 4 The present invention provides a manual and automatic azimuth and elevation angle drive adjustment device for a portable satellite station, including a support tripod 1, an adjustment base 2, an azimuth axis 5, an elevation axis 6, a first drive mechanism 7, a second drive mechanism 8, and an antenna dish 4. The bottom of the adjustment seat 2 is provided with an orientation axis 5, and the tripod 1 is connected to the orientation axis 5. The first drive mechanism 7 is connected to the adjustment seat 2 and is connected to the azimuth axis 5. It is used to drive the relative adjustment seat 2 to complete a 360° horizontal rotation to achieve azimuth angle adjustment. The surface of the adjustment base 2 is provided with a pitch axis 6, and the pitch axis 6 is connected to the antenna dish 4 through the connecting bracket 3; The second drive mechanism 8 is connected to the adjustment seat 2 and is connected to the pitch axis 6. It is used to drive the antenna dish 4 to complete a vertical rotation of 0°-90° to achieve the adjustment of the pitch angle. This application integrates the azimuth axis 5 and the elevation axis 6 into the same adjustment base 2, changing the traditional split layout and greatly saving installation space. The hollow and lightweight design not only reduces the overall weight, meeting the portability requirements of satellite portable stations, but also protects the core transmission components by utilizing the internal preset space, improving adaptability to outdoor environments. Furthermore, the azimuth axis 5 and the elevation axis 6 work together in the main adjustment base 2 without interfering with each other. With the worm gear 82 drive, they can achieve 360° continuous horizontal rotation of the azimuth angle and vertical rotation of the elevation angle from 0° to 90°. This independent dual-axis design ensures that the antenna beam can be pointed to any airspace position, meeting the satellite alignment requirements of satellites with different orbital inclinations.

[0015] In this embodiment, a drive motor and a transmission assembly are included. The drive motor is connected to the azimuth axis 5 through the transmission assembly, and the drive motor drives the azimuth axis 5 to rotate.

[0016] In this embodiment, the second drive mechanism 8 includes a worm gear 81, a worm 82, and a handwheel; The worm gear 81 is fixedly mounted on the pitch shaft 6 and meshes with the worm 82. A handwheel is fixedly mounted on one end of the worm 82. This application adopts a transmission method in which worm gear 82 meshes with worm wheel 81. By utilizing the large reduction ratio characteristic of worm gear 82 transmission, the output torque can be effectively increased while reducing the size of the motor, ensuring that the antenna can still rotate smoothly under loads such as strong winds. At the same time, worm gear 82 transmission itself has good self-locking characteristics, which can lock the azimuth and elevation angles instantly after the motor is powered off, without the need for an additional brake mechanism. This simplifies the structure and ensures the stability of the antenna pointing.

[0017] In this embodiment, the tripod 1 includes a base center connecting seat and three supporting legs. The bottom of the supporting legs is provided with leveling pads. The three supporting legs are evenly distributed in a triangle to support the entire antenna equipment.

[0018] Preferably, the support legs are telescopic rods.

[0019] Preferably, the transmission assembly is also connected to a control handwheel, which is used for manual fine-tuning or emergency operation in case of motor failure, realizing dual adaptation of automation and manual operation. Through the manual-automatic integrated structure, even non-professional communication personnel can complete satellite operation in emergency situations without relying on complex electronic auxiliary equipment, greatly reducing the difficulty of operation in harsh field environments.

[0020] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.

[0021] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
