It should be noted that similar reference numerals and letters indicate similar items in the following figures, and therefore, once an item is defined in one figure, it is not required to be further discussed in the subsequent figures.

According to one embodiment of the invention, a rocker device is provided. For example, a rocker device is used for a remote control of an unmanned aerial vehicle. As shown in Figures 1-4, the rocker assembly includes a frame, a rotating body, and a rocker assembly.

As shown in Figures 3-4, a first resilient member and a first directional bushing 15 are disposed on the frame. The frame forms a support for the rotating body. The first resilient member cooperates with the first directional bushing 15 to cause the first directional bushing 15 to form a pre-elastic force. The first direction bushing 15 has a first bevel 25 . The frame forms a stop for the rotation of the first direction bushing 15.

For example, the first elastic element is a spring, a spring piece or an elastic rubber piece. In this example, the first resilient element is the first compression spring 16. The first compression spring 16 abuts the first direction guide groove to generate a pre-elastic force. A rib 30 is provided on the first direction bushing 15. 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 guiding groove 19 is parallel to the first direction. The rib 30 is inserted into the first guiding groove 19 such that the first direction bushing 15 is along the first The guide groove 19 slides, and the first guide groove 19 prevents the first direction sleeve 15 from rotating.

Preferably, the rib 30 and the first guiding groove are respectively a plurality of ones, and the two are in one-to-one correspondence. The arrangement of the plurality of first guiding grooves and ribs 30 can more effectively prevent the first direction bushing 15 from rotating.

In other examples, the ribs 30 are located on the frame and the first guide slots are located on the first direction bushing 15. This configuration also prevents the first direction sleeve 15 from rotating. The first elastic element can also be a tension spring. The tension spring pulls the first direction bushing 15 to form a pre-elastic force.

The rotating body includes a rotating body, a first engaging portion, and a first rotating shaft 31. The first fitting portion and the first rotating shaft 31 are disposed 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 mating portion is configured to cooperate with the first direction bushing to achieve resetting of the rotating body.

The first rotating shaft 31 is pivotally coupled to the frame. The first mating portion includes a second bevel 26 disposed about the first axis of rotation 31. The first direction bushing 15 is sleeved on the first rotating shaft 31. In the initial position, the first slope 25 is in contact with the second slope 26. For example, the angles of the first bevel 25 and the second bevel 26 are complementary with respect to the first axis of rotation 31 such that the two bevels can be brought together. The first direction bushing 15 is slidable along the first rotation axis 31. The pre-elastic force of the first compression spring 16 against the first direction sleeve 15 is such that the second slope 26 forms a pressure on the first slope 25.

For example, the angle of the first slope 25 and the second slope 26 with respect to the first rotation shaft 31 is 30°-45°. This range of angles results in a better damping effect of the first direction bushing 15 on the rotating body.

A second elastic member and a second direction bushing 18 are disposed within the rotating body. The second resilient member cooperates with the second directional bushing 18 to cause the second directional bushing 18 to form a pre-elastic force. The second direction bushing 18 has a third bevel 27. The rotating body forms a stop for the rotation of the second direction bushing 18.

For example, the second elastic element is a spring, a spring piece or an elastic rubber piece. In this example, the second elastic element is the second compression spring 21. The first compression spring 16 abuts the first direction guide groove to generate a pre-elastic force. A rib 30 is provided on the second direction bushing 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 guiding groove 20 is parallel to the second direction. The rib 30 is inserted into the second guide groove 20 to slide the second direction bushing 18 along the second guide groove 20, and the second guide groove 20 prevents the second direction bushing 18 from rotating.

Preferably, the rib 30 and the second guiding groove are respectively a plurality of ones, and the two are in one-to-one correspondence. The arrangement of the plurality of second guiding grooves and ribs 30 can more effectively prevent the second direction sleeve 18 from rotating.

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

The rocker assembly includes a rocker body 12, a second mating portion, and a second pivot shaft 32. The second mating portion, the rocker body 12 and the second rotating shaft 32 are connected. The second rotating shaft 32 is pivotally coupled to the rotating body. The second mating portion includes a fourth bevel 28 disposed about the second axis of rotation 32. The second direction bushing 18 is sleeved on the second rotating shaft 32. In the initial position, the fourth slope 28 is attached to the third slope 27. The angles of the third bevel 27 and the fourth bevel 28 are complementary with respect to the second axis of rotation 32 so that the two bevels can be brought together. The second mating portion is configured to cooperate with the second direction bushing to achieve reset centering of the rocker body. The second direction sleeve 18 is slidable along the second axis of rotation 32. The pre-elastic force of the second compression spring 21 against the second direction bushing 18 causes the fourth slope 28 to exert pressure on the third slope 27.

For example, the angles of the third slope 27 and the fourth slope 28 with respect to the second rotation shaft 32 are 30°-45°. This range of angles results in a better damping effect of the second direction bushing 18 on the rocker body 12.

In use, the user manually drives the rocker body 12 to move in any direction. The movement causes the rotating body to rotate about a set axis (for example, the Y axis) and causes the rocker body 12 to swing about a set axis (for example, an X axis) to deviate the rotating body and the rocker body from the initial position. The rotation of the rotating body drives the first engaging portion to rotate, and the second inclined surface 26 also rotates. The first inclined surface 25 forms an interference with the second inclined surface 26 such that the first inclined surface 25 and the second inclined surface 26 are no longer fitted. The second inclined surface 26 pushes the first inclined surface 25 away from the second inclined surface 26, thereby pushing the first direction bushing 15 to slide along the first rotating shaft 31 in a direction away from the rotating body. The first direction bushing 15 compresses the first elastic element (eg, the first compression spring 16). And the pressure of the first compression spring 16 provides a damping effect of the rotating body rotating about the Y axis.

Similarly, the rocker body 12 swings to drive the second mating portion to rotate, and the fourth slope 28 also rotates. The third inclined surface 27 forms an interference with the fourth inclined surface 28 such that the third inclined surface 27 and the fourth inclined surface 28 are no longer fitted. The fourth slope 28 pushes the third slope 27 away from the fourth slope 28, thereby urging the second direction sleeve 18 to slide along the second rotation axis 32 in a direction away from the rocker body 12. The second direction sleeve 18 compresses the second resilient element (eg, the second compression spring 21). And the pressure of the second compression spring 21 provides a damping effect of the rocker body 12 rotating about the X axis.

When the user's hand releases the rocker body 12, the first elastic member (for example, the first compression spring 16) rebounds, thereby driving the first direction bushing 15 to slide in the opposite direction. The first ramp surface 25 of the first direction bushing 15 presses the second ramp surface 26 such that the second ramp surface 26 forms a torque. This torque causes the rotating body to reset to the initial position. Finally, the first bevel 25 and the second bevel 26 are reattached together, and the rotating body returns to the initial position.

Similarly, the second elastic member (for example, the second compression spring 21) rebounds, thereby driving the second direction sleeve 18 to slide in the opposite direction. The third bevel 27 of the second direction bushing 18 presses the fourth bevel 28 to cause the fourth bevel 28 to form a torque. This torque causes the rocker body 12 to reset to the initial position. Finally, the third bevel 27 and the fourth bevel 28 are reattached together, and the rocker body 12 is returned to the initial position.

The structure of the rocker device is simple, and the automatic reset of the rocker body 12 can be achieved.

In one example, as shown in Figures 3-5, the rotating body includes a curved surface 29. The frame includes curved edges that match the curvature of the curved surface 29, and the curved surface 29 slides along the curved edges. In this way, the curved edge forms a support for the curved surface 29, which makes the rotation of the rotating body smoother, and the rotating body is less prone to vibration and displacement, improving the reliability of the rocker device.

Optionally, the curved surface 29 is an ellipsoid or a spherical surface. These two curved faces 29 are smoother and have less resistance to rotation.

In one example, the rotating body includes a limiting groove 13 formed by the inward depression of the curved surface 29. The rocker body 12 passes through the limiting slot 13. The limit groove 13 is configured to define an angle at which the rocker body 12 rotates. As shown in FIG. 3, both ends of the limiting slot 13 form a stop for the rocker body 12, thereby defining the angle at which the rocker body 12 swings. For example, the angle of the rocker swing is 60°, which can meet the handling requirements of the unmanned aerial vehicle.

In one example, a stop 24 is provided on the frame. The stop portion 24 is for forming a stop 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 coupled to form a rotating space. For example, the connection is fixed by bolts. The rotating body is located in the rotating space. This arrangement makes it easy to install the rotating body. For example, the first bracket 11 has a curved edge. The curved edge surrounds the rotating space. The rotating space is a hollow space. The rotating body can rotate in the rotating space. For example, the first direction bushing 15 has two ribs 30, And the two ribs 30 are oppositely disposed. The guide grooves are respectively located on the first bracket 11 and the second bracket 17 to define the sliding direction of the two ribs 30.

As shown in FIGS. 3-4, a stopper portion 24 is provided on the first bracket 11. The stop portion 24 forms a stop for the lower portion of the rotating body to define an angle at which the rotating body rotates. In this way, the activity of the rotating body can be limited and it is easy to handle. For example, the rotating body has a rotation angle of 60°, which can meet the handling requirements of the unmanned aerial vehicle. Preferably, the stopper portion 24 and the lower cover 23 are integrally molded by injection molding. This makes the manufacture of the frame easy, and the connection strength of the stopper portion 24 and the lower cover 23 is high.

Preferably, the stop surface of the stop portion 24 matches the structure of the portion of the lower portion of the rotating body that is stopped. For example, the stop surface is in face-to-face contact with the stopped portion, so that stress concentration of the stopper portion 24 can be avoided. For example, the portion to be stopped is a flat surface, and the stop surface is a slope.

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 rotary cavity is formed between the upper cover 14 and the lower cover 23. The second resilient element, the second mating portion and the second direction bushing 18 are located in the rotating cavity. In this way, the installation of the rocker is made easy. For example, the ribs 30 of the second direction bushing 18 are two, and the two ribs 30 are oppositely disposed. The guide grooves are respectively located on the upper cover 14 and the lower cover 23 to define the sliding direction of the two ribs 30.

In one example, the curved surface 29 is located on the upper cover 14. Preferably, the first rotating shaft 31, the first mating portion and the upper cover 14 are integrally formed. For example, the first rotating shaft 31, the first fitting portion, and the upper cover 14 are integrally formed by injection molding. This makes the processing and manufacture of the rocker device easy, and the structural strength is high.

In one example, the rocker body 12, the second mating portion, and the second pivot shaft 32 are integrally formed. For example, the rocker body 12, the second fitting portion, and the second rotating shaft 32 are integrally formed by injection molding. This makes the processing and manufacture of the rocker device easy, and the structural strength is high.

While the invention has been described in detail with reference to the preferred embodiments of the present invention, it is understood that It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
