[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following describes the embodiments of the present utility model in detail with reference to the drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] In one aspect of the embodiments of the present application, a transmission mechanism is provided, as Figure 1 shown, including a support column 1, a mounting sleeve 2, a mounting frame 3, etc.

[0024] As Figures 1-4As shown in the figure, the mounting frame 3 has a receiving cavity and is applied to the main body of the satellite communication device during application, such as on the back of the antenna panel 7 of the satellite communication device. The upper part of the support column 1 is received in the receiving cavity and coaxially connected with a first bevel gear 11, and the lower part is used to connect with the bracket 6 of the satellite communication device.

[0025] On opposite sides of the mounting frame 3, a coaxial second bevel gear 41 and a third bevel gear 51 are respectively inserted; the second bevel gear 41 meshes with the first bevel gear 11, and the third bevel gear 51 meshes with the first bevel gear 11. The mounting sleeve 2 is received in the receiving cavity and is coaxially rotatably arranged on the upper part of the support column 1. Specifically, a matching part is coaxially provided on the upper part of the support column 1, the first bevel gear 11 is located above the matching part, and the lower part of the mounting sleeve 2 is rotationally matched with the matching part.

[0026] The mounting sleeve 2 is rotationally matched with the mounting frame 3, and the rotation axis is the same as the axis of the second bevel gear 41. The axes of the first bevel gear 11 and the third bevel gear 51 are perpendicular.

[0027] On opposite sides of the mounting frame 3, there are respectively through holes, and on opposite sides of the mounting sleeve 2, there are respectively through holes corresponding to the through holes. The shaft parts of the second bevel gear 41 and the third bevel gear 51 are respectively inserted through the corresponding through holes and through holes.

[0028] The power sources respectively used to drive the second bevel gear 41 and the third bevel gear 51 to rotate are installed on the mounting frame 3 or on the main body of the satellite communication device.

[0029] Specifically, the power source used to drive the second bevel gear 41 can be the first motor 4, and its output shaft is connected to the shaft part of the second bevel gear 41; the power source used to drive the third bevel gear 51 to rotate can be the second motor 5, and its output shaft is connected to the shaft part of the third bevel gear 51.

[0030] During application, when the power sources respectively drive the second bevel gear 41 and the third bevel gear 51 to rotate synchronously and in opposite directions, as Figure 5 shown in the figure, the output shaft of the first motor 4 rotates clockwise, and the output shaft of the second motor 5 rotates counterclockwise, driving the second bevel gear 41 and the third bevel gear 51 to rotate synchronously and in opposite directions. The first bevel gear 41, the second bevel gear 41, and the third bevel gear 51 are stuck and do not rotate. At this time, a reverse force is applied to the entire mechanism to achieve a pitching force in the opposite direction of the rotation of the power source, so as to drive the main body of the satellite communication device to pitch. As Figure 6 shown in the figure, by rotating the output shaft of the first motor 4 clockwise and the output shaft of the second motor 5 clockwise; or both rotate counterclockwise, thereby driving the second bevel gear 41 and the third bevel gear 51 to rotate synchronously and in opposite directions, and the second bevel gear 41 and the third bevel gear 51 rotate along the first bevel gear 41 to achieve the horizontal rotation of the main body of the device. Note that the rotation directions mentioned here are all from the perspective of the first motor 4 and the second motor 5 themselves.

[0031] Preferably, for the convenience of adaptability during use, the support column 1 is a telescopic column so as to enable the device main body connected to the transmission mechanism to be at different heights.

[0032] Another aspect of the embodiment of the present application provides a satellite communication device, such as Figure 4 shown, including the transmission mechanism described in the foregoing embodiment. The mounting frame 3 is mounted on the back of the antenna panel 7 of the satellite communication device. The pitching angle adjustment and the horizontal azimuth adjustment of the antenna panel 7 can be realized through the transmission mechanism.

[0033] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
