Description

Technical Field

[0001] This utility model relates to the field of space laser communication technology, and in particular to a servo mechanism for a laser communication terminal. Background Technology

[0002] Laser communication terminals are communication devices that use lasers as the transmission medium. They have extremely high transmission rates, far exceeding those of traditional microwave communication, and can meet the needs of large-capacity data transmission. At the same time, they have strong anti-electromagnetic interference capabilities, good signal directionality, and are not easily intercepted, resulting in higher security. In addition, the devices are small in size and have low power consumption, making them compatible with mobile platforms such as satellites and drones.

[0003] When adjusting the working angle, existing laser communication terminals typically use a single motor in conjunction with a drive gear and a driven gear, as disclosed in the utility model patent with authorization announcement number CN221648047U.

[0004] While the above solution can achieve multi-angle adjustment, it lacks the necessary rotation angle limiting structure. In case of misoperation, the adjusting shaft may cause the laser communication terminal to rotate excessively, i.e., the rotation angle exceeds 360 degrees. At this time, the cable connected to the laser communication terminal is easily pulled excessively, which may lead to damage.

[0005] Therefore, it is necessary to invent a servo mechanism for a laser communication terminal to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a servo mechanism for a laser communication terminal, which can realize multi-angle adjustment of the laser communication terminal without excessive rotation angle, effectively avoiding damage to the cable due to excessive pulling. This solves the problem that the existing solutions mentioned in the background art lack the necessary rotation angle limiting structure. When misoperation occurs, the adjusting shaft may cause the laser communication terminal to rotate excessively, i.e., the rotation angle exceeds 360 degrees. At this time, the cable connected to the laser communication terminal is easily excessively pulled, leading to damage.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a servo mechanism for a laser communication terminal, comprising:

[0008] A housing assembly that provides a mounting base for the communication terminal assembly and the servo drive assembly;

[0009] A communication terminal component, the communication terminal component being driven by a servo drive component; and

[0010] A servo drive assembly includes a fixed plate fixedly connected to the inner wall of the mounting housing. A servo motor is fixedly mounted on the bottom of the fixed plate. A rotating disk is drivenly connected to the top of the output shaft of the servo motor. An eccentric shaft is fixedly mounted on the top left side of the rotating disk. A push-pull plate is rotatably sleeved on the outside of the eccentric shaft through a bearing. A movable frame is rotatably connected to the bottom right end of the push-pull plate through a pin. A rack that meshes with a gear is fixedly mounted on the side of the movable frame.

[0011] According to at least one embodiment of the servo mechanism of the laser communication terminal of the present disclosure, the servo drive assembly further includes a guide slider fixedly disposed on the side of the moving frame, a guide shaft slidably disposed on the inner side of the guide slider, and the guide shaft being fixedly connected to the inner wall of the mounting housing.

[0012] According to at least one embodiment of the present disclosure, the servo mechanism of a laser communication terminal includes a housing assembly having an opening at its bottom.

[0013] According to at least one embodiment of the servo mechanism of the laser communication terminal of the present disclosure, a mounting plate is fixedly provided on the bottom front and bottom back of the mounting housing, and fixing holes are provided at both ends of the top of the mounting plate.

[0014] According to at least one embodiment of the present disclosure, a servo mechanism for a laser communication terminal includes a rotating shaft rotatably nested on the top of a mounting housing via a bearing, the top of which is fixedly connected to a laser communication terminal.

[0015] According to at least one embodiment of the servo mechanism of the laser communication terminal of the present disclosure, a transfer shaft is fixedly connected to the center of the bottom end of the rotating shaft, and a gear is fixedly sleeved on the bottom outer side of the rotating shaft.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention incorporates a servo drive component, enabling the servo motor to continuously rotate a rotating disk after startup. As the disk rotates, it repeatedly pushes and pulls a push-pull plate via an eccentric shaft. When the push-pull plate pushes the moving frame, the moving frame rotates counter-clockwise via a rack and pinion, thereby adjusting the working angle of the laser communication terminal. When the push-pull plate pulls the moving frame, the moving frame rotates clockwise via the rack and pinion. Compared to existing technologies, this invention allows for multi-angle adjustment of the laser communication terminal without excessive rotation angles, effectively preventing damage to the cable due to excessive pulling.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1This is a schematic diagram of the overall structure of the servo mechanism of a laser communication terminal according to one embodiment of the present disclosure.

[0028] Figure 2 This is a partial structural diagram of the housing assembly 1 and the communication terminal assembly 2 of the servo mechanism of a laser communication terminal according to one embodiment of the present disclosure.

[0029] Figure 3 This is a partial structural diagram of the communication terminal component 2 and the servo drive component 3 of the servo mechanism of a laser communication terminal according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the servo mechanism of the laser communication terminal disclosed herein may include components such as: housing assembly 1, communication terminal assembly 2, and servo drive assembly 3.

[0031] like Figure 2 As shown in this disclosure, the housing assembly 1 includes a mounting shell 11. The mounting shell 11 has an opening at its bottom. Mounting plates 12 are fixedly mounted on the bottom front and bottom back of the mounting shell 11. Both the mounting shell 11 and the mounting plate 12 are made of 6061 aluminum alloy, which is lightweight and has high strength, reducing the overall weight of the equipment and making it suitable for mobile platforms such as satellites and drones. Fixing holes 13 are provided at both ends of the top of the mounting plate 12.

[0032] Therefore, the wires connected to the mounting housing 11 can extend out through the opening, which facilitates the connection of the wires. At the same time, the mounting housing 11 can be installed and fixed using the fixing holes 13 on the mounting plate 12.

[0033] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the communication terminal assembly 2 includes a rotating shaft 21 that is rotatably nested on the top of the mounting housing 11 via a bearing. A laser communication terminal 22 is fixedly connected to the top of the rotating shaft 21, and a transfer shaft 23 is fixedly connected to the center of the bottom of the rotating shaft 21. Both the rotating shaft 21 and the rotating shaft 22 are made of 40Cr alloy steel, which has high hardness, strong wear resistance, and extended service life. A gear 24 is fixedly sleeved on the bottom outer side of the rotating shaft 21.

[0034] Therefore, when the gear 24 is driven to rotate by the rack 37, the gear 24 drives the laser communication terminal 22 to rotate synchronously with the rotating shaft 21 through the adapter shaft 23, thereby adjusting the working angle of the laser communication terminal 22.

[0035] like Figure 3As shown in this disclosure, the servo drive assembly 3 includes a fixed plate 31, made of aluminum alloy, which is fixedly connected to the inner wall of the mounting housing 11. A servo motor 32 is fixedly mounted at the bottom of the fixed plate 31. A rotating disk 33 is drivenly connected to the top of the output shaft of the servo motor 32. An eccentric shaft 34 is fixedly mounted on the top left side of the rotating disk 33. A push-pull plate 35 is rotatably sleeved on the outer side of the eccentric shaft 34 through a bearing. A movable frame 36, also made of aluminum alloy, is rotatably connected to the bottom right end of the push-pull plate 35 through a pin. A rack 37, which meshes with the gear 24, is fixedly mounted on the side of the movable frame 36. The servo drive assembly 3 also includes a guide slider 38, made of POM engineering plastic, which has good self-lubricating properties, reduces frictional resistance with the guide shaft 39, improves the sliding accuracy of the movable frame 36, and reduces operating noise. A guide shaft 39 is slidably mounted on the inner side of the guide slider 38. The guide shaft 39 is fixedly connected to the inner wall of the mounting housing 11.

[0036] Therefore, after the servo motor 32 is started, it drives the rotating disk 33 to rotate continuously. When the rotating disk 33 rotates, it pushes and pulls the push-pull plate 35 repeatedly through the eccentric shaft 34. When the push-pull plate 35 pushes the moving frame 36, the moving frame 36 drives the gear 24 to rotate counterclockwise through the rack 37, thereby adjusting the working angle of the laser communication terminal 22. When the push-pull plate 35 pulls the moving frame 36, the moving frame 36 drives the gear 24 to rotate clockwise through the rack 37. Compared with the existing technology, it can realize multi-angle adjustment of the laser communication terminal 22, and at the same time, it will not have the situation of excessive rotation angle, effectively avoiding the situation of cable being damaged due to excessive pulling.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
