[0001] This utility model relates to the field of mechanical transmission and motion control technology, and in particular to a minimally sized mechanism with two axes capable of multi-directional rotation. Background Technology

[0002] Commercial microsatellites typically use fixed installation methods for their flat-panel functional modules, such as antennas and battery arrays. Their physical orientation is rigidly bound to the satellite body. This installation method makes their performance affected by the satellite's orbital motion. When the satellite moves to a better position, its performance is enhanced, while when it moves to a less favorable position, its performance is weakened, making it unable to actively adapt to environmental changes.

[0003] In addition, although some movable structures have emerged, they can only achieve simple steering movements and cannot meet the needs of multi-directional adjustment. Furthermore, their prices are relatively high, which is not conducive to marketization. Utility Model Content

[0026] It is understood that the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, this embodiment provides a simplified mechanism with two axes capable of multi-directional rotation, including: a first driving member 1 and a second driving member 2 providing rotational motion; the second driving member 2 is fixed on the output shaft of the first driving member 1, and the output shaft of the second driving member 2 is connected to the load 3; wherein, the first driving member 1 has a rotational motion about the Y-axis, and the second driving member 2 has a rotational motion along the X-axis; through the cooperation of the first driving member 1 and the second driving member 2, the load 3 can be adjusted by multi-angle rotation.

[0029] Specifically, the first driving component 1 mainly includes a body, and an output shaft is provided at one of the longitudinal ends of the body. Preferably, a motor is used, and the rotor is driven to rotate by the magnetic field generated by the stator in the motor. The output shaft is connected to the rotor, and the rotational power is ultimately provided by the output shaft.

[0030] The second drive component 2 has the same structure as the first drive component 1, and is connected to the output shaft of the first drive component 1 via a first fixing component 4. The first fixing component 4 has a first mounting part 41 and a second mounting part 42. The first mounting part 41 is connected to the output shaft of the first drive component 1, and the second mounting part 42 is connected to the body of the second drive component 2. The first mounting part 41 and the output shaft of the first drive component 1, and the second mounting part 42 and the body of the second drive component 2 are either fixedly connected or detachably connected.

[0031] Specifically, the first mounting part 41 and the second mounting part 42 are integrally formed. The first mounting part 41 is a cylindrical structure with a mounting hole along its length. The cross-sectional shape of the mounting hole is adapted to the outer cross-sectional shape of the output shaft of the first drive member 1, and the depth is preferably sufficient to accommodate the length of the output shaft of the first drive member 1, so that the output shaft of the first drive member 1 can be inserted into the mounting hole to ensure sufficient contact surface between the two for a stable connection. The second mounting part 42 is a plate-like structure with a certain thickness. A receiving groove is provided through the cross-section of the plate-like structure. The size of the receiving groove is preferably sufficient not to obstruct the movement of the output shaft of the second drive member 2, so that the output shaft of the second drive member 2 can move smoothly when the second drive member 2 is fixed to the second mounting part 42. At the same time, a fixing surface is provided around the receiving groove, and the second mounting part 42 is connected to the second drive member 2 through the fixing surface. The size of the receiving groove can also be adapted to the cross-sectional shape of the body of the second drive member 2, so that the second mounting part 42 and the body of the second drive member 2 are fixed by a snap-fit ​​method.

[0032] In terms of connection methods, fixed connections include, but are not limited to, interference fit connections and welded connections; detachable connections include, but are not limited to, snap-fit ​​connections, threaded connections, pin connections, and plug-in connections, which can be selected according to the situation. When using fixed connections, the number of additional connecting parts can be reduced while ensuring the structural positional accuracy and stability, which can further reduce the size and weight of the equipment. When using detachable connections, a certain degree of structural stability can be ensured when fixed, and it is also convenient to replace or upgrade certain parts when needed, which facilitates maintenance and repair. Furthermore, some disassembled parts can be reused, further reducing costs.

[0033] A limiting part 43 is also provided on the first fixing member 1, located on the side facing the first driving member 1. The limiting part 43 can be a long strip-shaped protrusion or two smaller protrusions; when it is a long strip-shaped protrusion, it is installed as a whole on the side facing the first driving member 1; when it is two smaller protrusions, they are located at both ends of the side facing the first driving member 1, so as to limit the rotation of the second driving member 2 from 0° to 180°. The limiting part 43 is fixed to the first fixing member 1 in a detachable manner, or it is integrally formed with the first fixing member 1. It is worth noting that by limiting the rotation angle of the second driving member 2 by the limiting part 43, it is possible to effectively prevent the load 3 from colliding with other components of the satellite frame. The first fixing member 1 is preferably made of high-quality aluminum alloy, such as 6063-T6 aluminum alloy.

[0034] The output shaft of the second drive member 2 is connected to the load 3 via the second fixing member 5. The second fixing member 5 has a third mounting part 51 and a fourth mounting part 52. The third mounting part 51 is connected to the output shaft of the second drive member 2, and the fourth mounting part 52 is connected to the load 3. The third mounting part 51 and the output shaft of the second drive member 2, and the fourth mounting part 52 and the load 3 are either fixedly connected or detachably connected.

[0035] Specifically, the third mounting part 51 and the fourth mounting part 52 are integrally formed structures, which can be formed into a straight rod shape or into a "T" shape as shown in this embodiment, depending on the connection method.

[0036] When a "T"-shaped configuration as shown in this embodiment is adopted, the third mounting part 51 is a vertical arm, and the fourth mounting part 52 is a horizontal beam. A mounting hole is provided on the third mounting part 51. The cross-sectional shape of this mounting hole is adapted to the outer surface shape of the output shaft of the second drive member 2, and its depth is preferably sufficient to accommodate the length of the output shaft of the second drive member 2. If the thickness of the third mounting part 51 is insufficient, the mounting hole can be made through to ensure sufficient contact surface between the two, thereby enabling a stable connection. The fourth mounting part 52 is provided with connecting components according to the specific connection method. For example, when a fixed connection is used, the top surface can be directly connected to the load 3 by welding. When a detachable connection is used, for example, if it is a threaded connection, mounting holes can be provided on both the fourth mounting part 52 and the load 3, and then fixed with screws; if it is a snap-fit ​​connection, slots and snaps can be provided on both the fourth mounting part 52 and the load 3, and then the snaps can be aligned with the slots for locking; other methods are similar and will not be described in detail here.

[0037] It is understood that fixed connections include, but are not limited to, interference fit connections and welded connections; detachable connections include, but are not limited to, snap-fit ​​connections, threaded connections, pin connections, and plug-in connections, which can be selected adaptively according to the situation. When using fixed connections, the number of additional connecting parts can be reduced while ensuring the structural positional accuracy and stability, thereby further reducing the size and weight of the equipment; when using detachable connections, a certain degree of structural stability can be ensured when fixed, and it is also convenient to replace or upgrade certain parts when needed, facilitating maintenance and repair, and some disassembled parts can be reused, further reducing costs. It is worth noting that although some specific connection and installation methods are exemplified in the third mounting part 51 and the fourth mounting part 52, they are not intended as specific limitations, but rather as examples of feasible methods. For example, when the third mounting part 51 and the fourth mounting part 52 are straight rods, an interference fit can also be used between the fourth mounting part 52 and the load 3.

[0038] Furthermore, a third fixing member 6 is also provided; the third fixing member 6 has a fifth mounting part 61 and a sixth mounting part 62, the fifth mounting part 61 is connected to the body of the first driving member 1, and the sixth mounting part 62 is connected to the satellite frame. The fifth mounting part 61 is fixedly connected or detachably connected to the body of the first driving member 1; the sixth mounting part 62 is detachably connected to the satellite frame.

[0039] Specifically, the fifth mounting part 61 is a plate-like structure with a certain thickness and a through hole in the center. The size of the through hole is preferably such that it does not obstruct the movement of the output shaft of the first drive member 1, so that the output shaft of the first drive member 1 can move smoothly when it is fixed to the fifth mounting part 61. At the same time, a fixing surface is provided around the through hole, and four mounting holes are provided on the fixing surface. The fifth mounting part 61 is connected to the first drive member 1 through the four mounting holes on the fixing surface. The size of the through hole of the fifth mounting part 61 can also be adapted to the cross-sectional shape of the body of the first drive member 1, so that the fifth mounting part 61 is fixed to the body of the first drive member 1 by snap-fit. If it is fixed by snap-fit, there is no need to provide a fixing surface or provide mounting holes.

[0040] Around the fifth mounting part 61, there are six mounting parts 62 arranged at intervals. There are two or more sixth mounting parts 62, usually an even number, arranged symmetrically. The fifth mounting part 61 and the sixth mounting part 62 are integrally formed to ensure good rigidity, so as to have sufficient stability when the assembled mechanism is installed on the satellite frame.

[0041] During assembly, the first drive component 1 and the second drive component 2 are first connected to the load 3 via the first fixing component 4 and the second fixing component 5, respectively. Then, the first drive component 1 is fixed to the corresponding component on the satellite frame via the third fixing component 6, thereby completing the connection between the load 3 and the satellite frame. By controlling the rotation speed and sequence of the first drive component 1 and the second drive component 2 simultaneously or separately, the rotation speed and rotation position of the load 3 can be controlled.

[0042] Furthermore, the limiting part 43 restricts the second driving member 2 to rotate between 0° and 180° on the side away from the first driving member 1, thereby preventing the load 3 from colliding with other components of the satellite frame. Figures 6 to 8 As shown, schematic diagrams illustrate three attitudes of load 3 under the cooperation of two driving components. Figure 8 As can be seen, when the load 3 is adjusted to a position parallel to the X-axis, that is, when it moves to 0° or 180°, the load 3 can no longer rotate due to the limitation of the limiting part 43.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
