A vehicle-mounted mobile satellite antenna

Abstract

A vehicle-mounted mobile communication antenna includes a base cover and an antenna surface movably disposed within the base cover. The base cover contains an azimuth adjustment mechanism for adjusting the azimuth of the antenna surface and a pitch adjustment mechanism for adjusting the pitch angle of the antenna surface. The base cover also contains a frame for mounting the antenna surface, with support plates at both ends. The antenna surface has pitch axes at both ends that are rotatably connected to the support plates. A polarizer is mounted on the antenna surface, and a polarization adjustment mechanism for adjusting the polarizer angle is located at the bottom of the antenna surface. Compared to existing technologies, this antenna surface is driven to rotate by the pitch adjustment mechanism, and the antenna surface rotates around the pitch axis. During rotation, the overall height of the antenna surface is lower than in existing technologies, reducing the height of the antenna surface during angle adjustment. This reduces the space occupied by the antenna surface during rotation, decreases the overall size of the antenna, and consequently reduces the space required for the antenna to be mounted on the vehicle body.

Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide a vehicle-mounted mobile antenna that can reduce the antenna adjustment height and the space occupied.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a vehicle-mounted mobile antenna, comprising a base cover and an antenna surface movably disposed within the base cover. The base cover is provided with an azimuth adjustment mechanism for adjusting the azimuth of the antenna surface and a pitch adjustment mechanism for adjusting the pitch angle of the antenna surface. The base cover is provided with a frame for mounting the antenna surface, with support plates at both ends of the frame. The antenna surface is provided with pitch axes at both ends that are rotatably connected to the support plates. A polarizer is provided on the antenna surface, and a polarization adjustment mechanism for adjusting the angle of the polarizer is provided at the bottom of the antenna surface.

[0010] As a preferred embodiment of this utility model, the base plate is provided with an azimuth motor that drives the base plate to rotate, and the output end of the azimuth motor is provided with a rotating gear that meshes with the azimuth gear. The azimuth motor drives the rotating gear to move around the azimuth gear in a circumferential direction.

[0011] In a preferred embodiment of this utility model, the frame is mounted on the base plate, and the frame rotates synchronously with the base plate.

[0012] In a preferred embodiment of this utility model, the antenna surface is located on one side of the frame, and the pitch axis is connected to the end of the support plate.

[0013] In a preferred embodiment of this utility model, the pitch adjustment mechanism is mounted on a support plate at one end of the frame and is connected to the antenna surface.

[0014] As a preferred embodiment of this utility model, the pitch adjustment mechanism includes a pitch gear disposed at the end of the antenna surface and a pitch motor for driving the pitch gear to rotate, and the output end of the pitch motor is provided with a drive gear that meshes with the pitch gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The azimuth angle of the antenna surface is adjusted by the azimuth adjustment mechanism, and the elevation angle is adjusted by the elevation adjustment mechanism, thereby ensuring that the antenna surface and the satellite are always at the optimal connection angle. In addition, a frame for mounting the antenna surface is set inside the base, and a support plate for mounting the antenna surface is set at the end of the frame. The antenna surface is connected to the support plate through the elevation axis. The elevation adjustment mechanism drives the antenna surface to rotate, and the antenna surface rotates around the elevation axis as the rotation center. During rotation, the overall height of the antenna surface is lower than that of the existing technology, reducing the height of the antenna surface during the angle adjustment process. At the same time, the rotation angle of the antenna surface is 90 degrees. With the cooperation of the azimuth adjustment mechanism, the antenna surface does not need to rotate 180 degrees to achieve the effect of 180-degree adjustment of the antenna surface angle, thereby reducing the space occupied by the antenna surface during rotation, reducing the overall size of the antenna, and further reducing the space occupied by the antenna on the vehicle body.

[0019] 2. By driving the polarizer to rotate through the set polarization motor, the polarization can be adjusted. Compared with the fixed setting of the polarizer in the prior art, the polarization matching degree is improved by adjusting the polarization, thereby improving the reliability and anti-interference ability of the vehicle-mounted mobile communication.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-4As shown, a vehicle-mounted mobile communication antenna includes a base cover 1 and an antenna surface 2 movably disposed within the base cover 1. The base cover 1 is provided with an azimuth adjustment mechanism 3 for adjusting the azimuth of the antenna surface 2 and a pitch adjustment mechanism 4 for adjusting the pitch angle of the antenna surface 2. The base cover 1 is provided with a frame 102 for mounting the antenna surface 2. Both ends of the frame 102 are provided with support plates 1021. Both ends of the antenna surface 2 are provided with pitch shafts 201 that are rotatably connected to the support plates 1021. A polarizer 6 is provided on the antenna surface 2, and a polarization adjustment mechanism 5 for adjusting the angle of the polarizer 6 is provided at the bottom of the antenna surface 2.

[0027] Furthermore, the base cover 1 is designed as a circular structure, and the antenna surface 2 can move within this circular structure. The azimuth and elevation angles of the antenna surface 2 can be adjusted by the azimuth adjustment structure 3 and the elevation adjustment mechanism 4, so that the antenna surface 2 can always be set towards the satellite, thereby ensuring the stability of signal reception and transmission. The antenna surface 2 is connected to the support plate 1021 through the elevation axis 201. The elevation adjustment mechanism 4 drives the antenna surface 2 to rotate, and the antenna surface 2 rotates around the elevation axis 201 as the rotation center. When rotating, the overall height of the antenna surface 2 is lower than that of the prior art, which reduces the height of the antenna surface 2 during the angle adjustment process, thereby reducing the space occupied by the antenna surface 2 during rotation, reducing the overall volume of the antenna, and thus reducing the space occupied by the antenna on the vehicle body.

[0028] The base cover 1 is provided with a rotating base plate 101, and the azimuth adjustment mechanism 3 is provided on the base plate 101. The antenna surface 2 is located above the base plate 101 and moves synchronously with the base plate 101. Furthermore, the base plate 101 is provided in the base cover 1, and the azimuth adjustment mechanism 3 is provided on the base plate 101. The azimuth adjustment mechanism 3 drives the base plate 101 to rotate, thereby driving the antenna surface 2 to rotate synchronously.

[0029] Specifically, the orientation adjustment mechanism 3 includes an orientation gear 301 fixedly mounted on the base cover 1, a base plate 101 rotatably connected to the orientation gear 301, the orientation gear 301 being located in the middle of the base cover 1, a bearing connected to the orientation gear 301 being located in the middle of the base plate 101, the base plate 101 being sleeved on the outer wall of the bearing, the orientation gear 301 being fixedly connected to the inner wall of the bearing via a connecting shaft, an orientation motor 302 driving the base plate 101 to rotate being mounted on the base plate 101, and a rotating gear 3021 meshing with the orientation gear 301 being mounted at the output end of the orientation motor 302, the orientation motor 302 driving the rotating gear 3021 to rotate around the orientation gear 301. 01. Circumferential movement: The azimuth motor 302 is fixedly mounted on the upper surface of the base plate 101, and the output end of the azimuth motor 302 passes through the base plate 101. The rotating gear 3021 is connected to the output end of the azimuth motor 302, and the azimuth motor 302 is located on the lower surface of the base plate 101. The rotating gear 3021 meshes with the azimuth gear 301, and the azimuth motor 302 drives the rotating gear 3021 to rotate. While rotating on its own axis, the rotating gear 3021 revolves around the azimuth gear 301 along the circumferential direction, thereby causing the base plate 101 to rotate in the base cover 1, thus realizing the adjustment of the azimuth angle of the antenna surface 2.

[0030] The frame 102 is mounted on the base plate 101 and rotates synchronously with the base plate 101. Furthermore, the frame 102 is fixedly mounted on the base plate 101, and the antenna surface 2 is located on the frame 102. The frame 102 and the antenna surface 2 rotate with the rotation of the base plate 101.

[0031] Antenna surface 2 is located on one side of frame 102, and pitch axis 201 is connected to the end of support plate 1021. Furthermore, support plate 1021 is vertically arranged at both ends of frame 102, and the two support plates 1021 are arranged in parallel. Pitch axis 201 is arranged along the length direction of antenna surface 2. Antenna surface 2 is mounted on frame 102 through pitch axis 201 and rotates on frame 102 through pitch axis 201. In addition, one end of support plate 1021 is connected to frame 102, and the other end is connected to pitch axis 201, so that antenna surface 2 is located on one side of frame 102. When antenna surface 2 rotates 90 degrees, antenna surface 2 is located above frame 102 and antenna surface 2 is in a horizontal state. With the cooperation of azimuth adjustment mechanism 3, the antenna surface angle can be adjusted by 180 degrees without rotating 180 degrees.

[0032] The pitch adjustment mechanism 4 is mounted on a support plate 1021 at one end of the frame 102. The pitch adjustment mechanism 4 is connected to the antenna surface 2. Further, the pitch adjustment mechanism 4 includes a pitch gear 402 mounted at one end of the antenna surface 2 and a pitch motor 401 that drives the pitch gear 402 to rotate. The output end of the pitch motor 401 is provided with a drive gear 4011 that meshes with the pitch gear 402. The pitch gear 402 is connected to a pitch shaft 201 at one end of the antenna surface 2. The pitch motor 401... 1. The pitch gear 402 is fixedly connected to the pitch shaft 201 and is mounted on the support plate 1021. The output end of the pitch motor 401 passes through the support plate 1021 and is mounted on the output end of the pitch motor 401. The drive gear 4011 is meshed with the pitch gear 402. The pitch motor 401 drives the drive gear 4011 and the pitch gear 402 to rotate synchronously, thereby driving the antenna surface 2 to rotate, thus realizing the adjustment of the pitch angle of the antenna surface 2.

[0033] The pitch axis 201 is located at the middle of the end of the antenna surface 2, so that the pitch axis 201 coincides with the center of gravity of the antenna surface 2, which greatly reduces the pitch rotation inertia, lowers the rotation height of the antenna surface 2, makes the antenna control more flexible and reduces energy consumption.

[0034] The polarization adjustment mechanism 5 includes a polarization motor 501 for driving the polarizer 6 to rotate. The output end of the polarization motor 501 is provided with a drive pulley 5011, and a driven pulley 502 is connected to the polarizer 6.

Further, the polarizer 6 includes a transmitting polarizer and a receiving polarizer, which are respectively located at both ends of the bottom surface of the antenna surface 2. A polarization motor 501 for adjusting the angle of the transmitting polarizer is provided at the transmitting polarizer. A driven pulley 502 is provided on the transmitting polarizer, and a drive pulley 5011 is provided at the output end of the polarization motor 501. The drive pulley 5011 and the driven pulley 502 are connected by the synchronous belt 503. Under the action of the polarization motor 501, the transmitting polarizer is driven to rotate, thereby adjusting the angle of the transmitting polarization.

[0035] A polarization motor 501 is also provided at the receiving polarizer. A driven pulley 502 is provided on the receiving polarizer. A driving pulley 5011 is provided at the output end of the polarization motor 501. The driving pulley 5011 and the driven pulley 502 are connected by a synchronous belt 503.
