In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

According to one embodiment of the present invention, a rocker device is provided. For example, rocker devices are used for remote control devices of unmanned aircraft. As shown in fig. 1-4, the rocker device includes a frame, a rotor, and a rocker assembly.

As shown in fig. 3-4, a first resilient element and a first directional sleeve 15 are provided on the frame. The frame forms a support for the rotor. The first elastic member is engaged with the first direction sleeve 15 to form a pre-elastic force to the first direction sleeve 15. The first directional sleeve 15 has a first bevel 25. The frame forms a stop for the rotation of the first directional sleeve 15.

For example, the first elastic element is a spring, a shrapnel or an elastic rubber member. In this example, the first resilient element is a first compression spring 16. The first compression spring 16 is abutted against the first direction guide groove to generate a pre-elastic force. The first direction sleeve 15 is provided with a rib 30. The extending direction of the rib 30 is parallel to the first direction. A first guide groove 19 is provided on the frame. The extending direction of the first guide groove 19 is parallel to the first direction. The rib 30 is inserted into the first guide groove 19 so that the first direction boss 15 slides along the first guide groove 19, and the first guide groove 19 prevents the first direction boss 15 from rotating.

Preferably, the rib 30 and the first guide groove are respectively plural and correspond one to one. The provision of the plurality of first guide grooves and the rib 30 can more effectively prevent the rotation of the first direction sleeve 15.

In other examples, the rib 30 is located on the frame and the first guide groove is located on the first direction sleeve 15. This structure also prevents the first direction sleeve 15 from rotating. The first elastic element may also be a tension spring. The tension spring pulls the first direction sleeve 15 to form a pre-spring force.

The rotor includes a rotor body, a first fitting portion, and a first rotation shaft 31. The first engaging portion and the first rotating shaft 31 are provided on the rotating body. For example, the first mating portion and the first rotating shaft 31 are located on the outer surface of the rotating body. The first matching part is used for matching with the first direction shaft sleeve so as to realize resetting and centering of the rotating body.

The first rotation shaft 31 is pivotally connected to the frame. The first mating portion includes a second bevel 26 disposed about a first rotational axis 31. The first direction sleeve 15 is sleeved on the first rotating shaft 31. In the initial position, the first inclined surface 25 is attached to the second inclined surface 26. For example, the angles of the first and second

inclined surfaces

25, 26 are complementary with respect to the first rotational axis 31 so that the two inclined surfaces can fit together. The first direction sleeve 15 is slidable along a first rotation shaft 31. The first compression spring 16 pre-biases the first direction sleeve 15 such that the second inclined surface 26 forms a pressure force against the first inclined surface 25.

For example, the first inclined surface 25 and the second inclined surface 26 have an angle of 30 ° to 45 ° with respect to the first rotation axis 31. This angular range allows the damping effect of the first directional sleeve 15 on the rotating body to be better.

A second resilient element and a second directional sleeve 18 are provided within the rotating body. The second elastic member is engaged with the second direction sleeve 18 to form a pre-elastic force to the second direction sleeve 18. The second directional sleeve 18 has a third chamfer 27. The rotation of the rotating body to the second direction sleeve 18 forms a stop.

For example, the second elastic element is a spring, a shrapnel or an elastic rubber member. In this example, the second elastic element is a second compression spring 21. The first compression spring 16 is abutted against the first direction guide groove to generate a pre-elastic force. A rib 30 is provided on the second directional sleeve 18. The extending direction of the rib 30 is parallel to the second direction. A second guide groove 20 is provided in the rotating body. The extending direction of the second guide groove 20 is parallel to the second direction. The rib 30 is inserted into the second guide groove 20 such that the second direction boss 18 slides along the second guide groove 20, and the second guide groove 20 prevents the second direction boss 18 from rotating.

Preferably, the rib 30 and the second guide groove are respectively plural and correspond one to one. The provision of a plurality of second guide grooves and ribs 30 more effectively prevents rotation of the second directional sleeve 18.

In other examples, the rib 30 is located on the rotating body and the second guide slot is located on the second directional sleeve 18. This structure also prevents the second direction sleeve 18 from rotating. The second elastic element may also be a tension spring. The tension spring pulls the second direction sleeve 18 to form a pre-spring force.

The rocker assembly includes a rocker body 12, a second mating portion, and a second rotational shaft 32. The second mating portion, the rocker body 12 and the second rotating shaft 32 are connected. The second rotation shaft 32 is pivotally connected to the rotation body. The second mating portion includes a fourth ramp 28 disposed about a second rotational axis 32. The second direction sleeve 18 is sleeved on the second rotating shaft 32. In the initial position, the fourth inclined surface 28 is in contact with the third inclined surface 27. The angles of the third and

fourth ramps

27, 28 are complementary with respect to the second axis of rotation 32 so that the two ramps can fit together. The second matching part is used for matching with the second direction shaft sleeve so as to realize resetting and centering of the rocker body. The second directional sleeve 18 is slidable along a second rotational axis 32. The pre-spring force of the second compression spring 21 against the second directional sleeve 18 causes the fourth inclined surface 28 to exert a compressive force on the third inclined surface 27.

For example, the angle of the third inclined surface 27 and the fourth inclined surface 28 with respect to the second rotation axis 32 is 30 ° to 45 °. This angular range provides a better damping effect of the second directional sleeve 18 on the rocker body 12.

In use, a user manually drives the rocker body 12 in any direction. This movement causes the rotating body to rotate about a set axis (e.g., Y axis) and the rocker body 12 to oscillate about a set axis (e.g., X axis) to deviate the rotating body and the rocker body from an initial position. The rotation of the rotating body drives the first mating portion to rotate, and the second inclined surface 26 also rotates. The first inclined surface 25 and the second inclined surface 26 interfere with each other, so that the first inclined surface 25 and the second inclined surface 26 are not attached. The second inclined surface 26 pushes the first inclined surface 25 away from the second inclined surface 26, thereby pushing the first direction sleeve 15 to slide along the first rotation shaft 31 in a direction away from the rotation body. The first direction sleeve 15 compresses a first elastic member (e.g., a first compression spring 16). And the pressure of the first compression spring 16 provides a damping effect of the rotation of the rotating body about the Y-axis.

Similarly, the rocker body 12 swings to drive the second matching portion to rotate, and the fourth inclined surface 28 also rotates. The third inclined surface 27 interferes with the fourth inclined surface 28, so that the third inclined surface 27 and the fourth inclined surface 28 are not attached. The fourth inclined surface 28 pushes the third inclined surface 27 away from the fourth inclined surface 28, thereby pushing the second direction sleeve 18 to slide along the second rotation shaft 32 in a direction away from the rocker body 12. The second direction sleeve 18 compresses the second elastic member (e.g., the second compression spring 21). And the pressure of the second compression spring 21 provides a damping effect of the rotation of the rocker body 12 about the X-axis.

When the user's hand releases the rocker body 12, a first resilient element (e.g., a first compression spring 16) springs back, driving the first direction sleeve 15 to slide in the opposite direction. The first inclined surface 25 of the first direction sleeve 15 presses the second inclined surface 26 so that the second inclined surface 26 forms a torque. The torque returns the rotating body toward the initial position. Finally, the first inclined surface 25 and the second inclined surface 26 are attached again, and the rotating body returns to the initial position.

Likewise, the second elastic member (e.g., the second compression spring 21) is sprung back, thereby driving the second-direction boss 18 to slide reversely. The third inclined surface 27 of the second directional sleeve 18 presses the fourth inclined surface 28 so that the fourth inclined surface 28 forms a torque. This torque returns the rocker body 12 toward the initial position. Finally, the third inclined surface 27 and the fourth inclined surface 28 are attached again, and the rocker body 12 returns to the initial position.

The rocker device has a simple structure and can realize automatic resetting and centering of the rocker body 12.

In one example, as shown in fig. 3-5, the rotating body includes a cambered surface 29. The frame includes an arcuate edge that matches the arc of the arcuate surface 29, and the arcuate surface 29 slides along the arcuate edge. In this way, the arc-shaped edge forms a support for the arc-shaped surface 29, which makes the rotation of the rotating body smoother, and the vibration and the deflection of the rotating body do not easily occur, improving the reliability of the rocker device.

Alternatively, the arcuate surface 29 is an ellipsoid or spherical surface. The two cambered surfaces 29 are smoother and have less resistance in rotation.

In one example, the rotating body includes a limit groove 13 formed by an inward depression of the arcuate surface 29. The rocker body 12 passes through the limit groove 13. The limiting groove 13 is configured to limit an angle at which the rocker body 12 rotates. As shown in fig. 3, two ends of the limiting groove 13 form a stop for the rocker body 12, so that the swinging angle of the rocker body 12 is limited. For example, the swing angle of the rocker is 60 degrees, and the swing angle can meet the control requirement of the unmanned aerial vehicle.

In one example, a stop 24 is provided on the frame. The stopper 24 serves to form a stopper for the rotating body to define an angle at which the rotating body rotates.

For example, the frame includes a first bracket 11 and a second bracket 17. The first bracket 11 and the second bracket 17 are fixedly connected to form a rotation space. For example, by bolting. The rotating body is located in the rotating space. This arrangement facilitates the mounting of the rotating body. For example, the first bracket 11 has an arc-shaped edge. The arcuate edge encloses the rotational space. The rotating space is a hollowed-out space. The rotating body is rotatable in the rotating space. For example, the ribs 30 of the first-direction boss 15 are two, and the two ribs 30 are provided opposite to each other. Guide grooves are respectively provided on the first bracket 11 and the second bracket 17 to define the sliding directions of the two ribs 30.

As shown in fig. 3 to 4, a stopper 24 is provided on the first bracket 11. The stopper 24 forms a stopper for the lower portion of the rotating body to define an angle at which the rotating body rotates. The activity of the rotating main body can be limited in this way, and the operation and control are convenient. For example, the rotation angle of the rotating body is 60 degrees, and the angle can meet the operation requirement of the unmanned aerial vehicle. Preferably, the stopper 24 is integrally formed with the lower cover 23 by injection molding. This facilitates the manufacture of the frame and the strength of the connection of the stopper 24 to the lower cover 23 is high.

Preferably, the stop surface of the stop 24 matches the configuration of the portion of the lower part of the rotating body that is stopped. For example, the stop surface is in surface-to-surface contact with the portion to be stopped, so that stress concentration of the stop portion 24 can be avoided. For example, the portion to be stopped is a plane, and the stop surface is an inclined surface.

In one example, as shown in fig. 3, the rotating body includes a lower cover 23 and an upper cover 14 that are coupled together. For example by bolting. A rotation chamber is formed between the upper cover 14 and the lower cover 23. The second resilient element, the second mating portion and the second directional sleeve 18 are located in the rotation chamber. In this way, the mounting of the rocker is facilitated. For example, the ribs 30 of the second directional sleeve 18 are two, and the two ribs 30 are disposed opposite to each other. Guide grooves are respectively provided on the upper cover 14 and the lower cover 23 to define the sliding directions of the two ribs 30.

In one example, the arcuate surface 29 is located on the upper cover 14. Preferably, the first rotation shaft 31, the first fitting portion, and the upper cover 14 are integrally formed. For example, the first rotating shaft 31, the first engaging portion, and the upper cover 14 are integrally formed by injection molding. This facilitates the machining and manufacturing of the rocker device and has a high structural strength.

In one example, the rocker body 12, the second mating portion, and the second rotational shaft 32 are integrally formed. The rocker body 12, the second mating portion, and the second rotation shaft 32 are integrally formed, for example, by injection molding. This facilitates the machining and manufacturing of the rocker device and has a high structural strength.
