Description

Technical Field

[0001] This invention relates to the field of aircraft technology, and in particular to a tilting device and an aircraft. Background Technology

[0002] In existing technology, an aircraft includes an aircraft body, a tilting device disposed on the aircraft body, and a propeller driven and connected to the tilting device. The tilting device is used to tilt the propeller, thereby providing the aircraft with the propulsion for flight. For example, during the vertical takeoff and landing of the aircraft, the rotation axis of the propeller extends in the vertical direction to provide the aircraft with the propulsion for takeoff and landing; during the level flight of the aircraft, the tilting device tilts the propeller so that the rotation axis of the propeller extends in the horizontal direction to provide the aircraft with the propulsion for level flight.

[0003] The aircraft's tilting mechanism includes a propeller motor connected to the propeller drive and a tilting motor connected to the propeller motor drive. The tilting motor tilts the propeller motor, thereby indirectly tilting the propeller. However, currently, the propeller motor is directly fixed to the output shaft of the tilting motor, which causes the output shaft of the tilting motor to be subjected to a large torque, greatly reducing the service life of the tilting motor. Summary of the Invention

[0004] The main objective of this invention is to provide a tilting device that avoids the output shaft of the tilting motor being subjected to a large force continuously, thereby improving the service life of the tilting motor.

[0005] To achieve the above objectives, the tilting device proposed in this invention includes:

[0006] Base;

[0007] The linkage mechanism includes a motor mounting base rotatably connected to the base, a connecting rod having a first end and a second end, and a rocker having a third end and a fourth end, wherein the first end is rotatably connected to the motor mounting base, and the second end is rotatably connected to the third end;

[0008] A propeller motor, detachably connected to the motor mounting base, the propeller motor being used to drive a propeller; and

[0009] A tilting motor is mounted on the base, and the output shaft of the tilting motor is drivenly connected to the fourth end.

[0010] The tilting device has a first state and a second state. In the first state and the second state, the first end, the second end and the fourth end are all located on the same straight line. The position of the second end in the first state is different from the position in the second state.

[0011] Optionally, when the first state transitions to the second state, the angle through which the motor mounting bracket rotates is greater than 80 degrees and less than 100 degrees.

[0012] Optionally, the tilting device further includes an adapter seat disposed on the base, and the base is rotatably connected to the motor mounting base through the adapter seat.

[0013] Optionally, the motor mounting base has a first abutment portion, and the adapter has a second abutment portion opposite to the first abutment portion in the rotation direction of the motor mounting base. During the transition from the first state to the second state, the first abutment portion approaches the second abutment portion, and in the second state, the first abutment portion abuts against the second abutment portion.

[0014] Optionally, the connecting rod includes a third abutment portion disposed between the first end and the second end, and the rocker arm has a fourth abutment portion. In the direction in which the connecting rod rotates relative to the rocker arm, the third abutment portion is opposite to the fourth abutment portion. During the transition from the second state to the first state, the third abutment portion approaches the fourth abutment portion, and in the first state, the third abutment portion abuts against the fourth abutment portion.

[0015] Optionally, the motor mounting base includes a mounting base body for mounting the propeller motor and a plurality of support lugs connected to the mounting base body, the support lugs being rotatably connected to the base.

[0016] Optionally, the tilting device further includes a second support seat disposed on the base, and the output shaft rotatably passes through the second support seat.

[0017] Optionally, multiple second support seats are provided, and the rocker arm is located between two second support seats.

[0018] Optionally, the motor mounting base is located on one side of the base, and the tilting motor is located on the opposite side of the base.

[0019] Optionally, the tilting device further includes a limiting shell disposed on the base, the tilting motor being disposed inside the limiting shell, and the limiting shell having weight reduction holes.

[0020] Optionally, the base is provided with a mounting groove, and the tilting device further includes a connector installed in the mounting groove and a pressing member that presses the connector against the bottom of the mounting groove, the pressing member being provided on the base.

[0021] Optionally, in the first state, the fourth end is located between the first end and the second end, and in the second state, the second end is located between the first end and the fourth end.

[0022] Optionally, the tilt motor is configured as a tilt servo.

[0023] The present invention also proposes an aircraft, the aircraft comprising:

[0024] The main body of the aircraft;

[0025] The aforementioned tilting device has a base located on the main body of the aircraft; and a propeller is driven and connected to the propeller motor of the tilting device.

[0026] In the technical solution of this invention, the tilting device includes a base, a linkage mechanism, a propeller motor, and a tilting motor. The linkage mechanism includes a motor mounting base rotatably connected to the base, a connecting rod having a first end and a second end, and a rocker having a third end and a fourth end. The first end is rotatably connected to the motor mounting base, and the second end is rotatably connected to the third end. The propeller motor is mounted on the motor mounting base and drives the propeller. The tilting motor is mounted on the base, and its output shaft is driven by the fourth end. Thus, the output shaft of the tilting motor drives the rocker to rotate, the rocker drives the connecting rod to move, the connecting rod drives the motor mounting base to move, and consequently, drives the propeller motor mounted on the motor mounting base to move. In other words, the tilting motor indirectly tilts the propeller motor through the linkage mechanism. Because the motor mounting base is connected to the base, a portion of the force transmitted from the propeller motor is borne by the base, reducing the other portion of the force transmitted to the output shaft of the tilting motor through the linkage mechanism. This avoids the output shaft of the tilting motor being constantly subjected to a large force, increasing the service life of the tilting motor and reducing the requirement for vibration resistance. The tilting device has a first state and a second state. In both states, the first, second, and fourth ends are aligned on the same straight line, but the position of the second end differs between the first and second states. It can be understood that the linkage mechanism has two dead points for the motor mount. When the linkage mechanism is in these two dead points, the tilting device is in the first and second states respectively. Even if the motor mount is subjected to external force, the tilting device will not disengage from either state. In other words, the tilting device achieves self-locking in both states, preventing additional torque on the output shaft of the tilting motor when the motor mount is subjected to external force. Therefore, in both states, the tilting motor does not need to continuously output a large torque to maintain the stability of the entire system, increasing the service life of the tilting motor. It is worth noting that the tilting device can disengage from the first and second states by being driven by the tilting motor. Furthermore, the propeller motor is detachably connected to the motor mount, facilitating replacement when the propeller motor is damaged. Attached Figure Description

[0045] This invention proposes a tilting device designed to prevent the output shaft of a tilting motor from being subjected to excessive force, thereby improving the service life of the tilting motor.

[0046] Reference Figures 1 to 9In one embodiment of the present invention, the tilting device 100 includes a base 200, a linkage mechanism 300, a propeller motor 400, and a tilting motor 500. The linkage mechanism 300 includes a motor mounting base 310 rotatably connected to the base 200, a connecting rod 320 having a first end 321 and a second end 322, and a rocker arm 330 having a third end 331 and a fourth end 332. The first end 321 is rotatably connected to the motor mounting base 310, and the second end 322 is rotatably connected to the third end 331. The propeller motor 400 is mounted on the motor mounting base 310 and is used to drive a propeller. The tilting motor 500 is mounted on the base 200, and the output shaft 510 of the tilting motor 500 is drivenly connected to the fourth end 332. Thus, the output shaft 510 of the tilt motor 500 can drive the rocker arm 330 to rotate, the rocker arm 330 drives the connecting rod 320 to move, the connecting rod 320 drives the motor mounting base 310 to move, and in turn drives the propeller motor 400 mounted on the motor mounting base 310 to move. That is, the tilt motor 500 indirectly tilts the propeller motor 400 through the connecting rod mechanism 300. Since the motor mounting base 310 is connected to the base 200, part of the force transmitted from the propeller motor 400 is borne by the base 200, reducing the other part of the force transmitted to the output shaft 510 of the tilt motor 500 through the connecting rod mechanism 300. This avoids the output shaft 510 of the tilt motor 500 being subjected to a large force all the time, improves the service life of the tilt motor 500, and reduces the requirement for the tilt motor 500 to have anti-vibration capability. The tilting device 100 has a first state and a second state. In both states, the first end 321, the second end 322, and the fourth end 332 are all located on the same straight line. The position of the second end 322 is different in the first and second states. It can be understood that, for the motor mounting base 310, the linkage mechanism 300 has two dead-point positions. When the linkage mechanism 300 is located at these two dead-point positions, the tilting device 100 is in the first and second states respectively. Even if the motor mounting base 310 is subjected to external force, the tilting device 100 will not disengage from the first and second states. That is, the tilting device 100 achieves self-locking in both states, thus preventing the force transmission from generating additional torque on the output shaft 510 of the tilting motor 500 when the motor mounting base 310 is subjected to external force. Therefore, in both states, the tilting motor 500 does not need to continuously output a large torque to maintain the stability of the entire system, increasing the service life of the tilting motor 500. It is worth mentioning that the tilting device 100 can be driven by the tilting motor 500 to disengage from the first and second states. In addition, the propeller motor 400 is detachably connected to the motor mounting base 310, so that when the propeller motor 400 is damaged, it is easy to replace it with a new propeller motor 400.

[0047] It should be noted that in the first state and the second state, the first end 321, the second end 322, and the fourth end 332 are all located on the same straight line, which means that when the linkage mechanism 300 is abstracted into a planar linkage mechanism 300, in the first state and the second state, the first end 321, the second end 322, and the fourth end 332 are all located on the same straight line.

[0048] The angle through which the motor mounting base 310 rotates from the first state to the second state can be set according to actual needs. Optionally, in one embodiment, the angle through which the motor mounting base 310 rotates from the first state to the second state is greater than 80 degrees and less than 100 degrees. Without loss of generality, the angle through which the motor mounting base 310 rotates is 90 degrees. Thus, when the tilting device 100 is applied to an aircraft, the rotation axis of the propeller, which is driven and connected to the propeller motor 400, can have a state extending along the forward and backward direction of the aircraft and a state extending along the vertical direction of the aircraft, thereby enabling the aircraft's propeller to provide power for level flight and vertical take-off and landing.

[0049] Optionally, in one embodiment, the tilting device 100 further includes an adapter 600 disposed on the base 200, and the base 200 is rotatably connected to the motor mounting base 310 through the adapter 600. This allows for more flexible assembly of the motor mounting base 310. Of course, in other embodiments, the motor mounting base 310 can also be directly rotatably connected to the base 200 to reduce the assembly steps of the tilting device 100.

[0050] Optionally, in one embodiment, the motor mounting base 310 has a first abutment portion 314, and the adapter 600 has a second abutment portion 610 opposite to the first abutment portion 314 in the rotation direction of the motor mounting base 310. During the transition from the first state to the second state, the first abutment portion 314 approaches the second abutment portion 610, and in the second state, the first abutment portion 314 abuts against the second abutment portion 610. That is, when the first abutment portion 314 abuts against the second abutment portion 610, the tilting device 100 enters the second state, allowing the linkage mechanism 300 to reach the dead point position more accurately. This avoids the situation where the tilting motor 500 malfunctions, making it difficult for the tilting device 100 to enter the second state. However, this design is not limited to this. In other embodiments, the motor mounting base 310 is directly rotatably connected to the base 200. The base 200 is provided with a fifth abutment that is opposite to the first abutment 314 in the rotation direction of the motor mounting base 310. During the transition from the first state to the second state, the first abutment 314 approaches the fifth abutment, and in the second state, the first abutment 314 abuts against the fifth abutment.

[0051] Optionally, in one embodiment, the connecting rod 320 includes a third abutment 323 disposed between the first end 321 and the second end 322, and the rocker arm 330 has a fourth abutment 334. In the direction of rotation of the connecting rod 320 relative to the rocker arm 330, the third abutment 323 and the fourth abutment 334 are opposite each other. During the transition from the second state to the first state, the third abutment 323 approaches the fourth abutment 334, and in the first state, the third abutment 323 abuts against the fourth abutment 334. That is, when the third abutment 323 abuts against the fourth abutment 334, the tilting device 100 enters the first state, so that the connecting rod mechanism 300 can reach the dead point position more accurately. In this way, the situation where the tilting motor 500 fails and the tilting device 100 has difficulty entering the first state can be avoided. However, this design is not limited to this. In other embodiments, the base 200 is provided with a sixth abutment. As long as the third abutment 323 abuts against the sixth abutment, the tilting device 100 can enter the first state.

[0052] Optionally, in one embodiment, the connecting rod 320 is bent so that when the third abutment 323 abuts against the fourth abutment 334, the first end 321, the second end 322, and the fourth end 332 can be located in a straight line. Of course, in other embodiments, the shape of the rocker arm 330 can also be changed so that the first end 321, the second end 322, and the fourth end 332 can be located in a straight line.

[0053] Optionally, in one embodiment, the motor mounting base 310 includes a mounting base body 311 for mounting the propeller motor 400, and a plurality of support lugs 312 connecting the mounting base body 311, the support lugs 312 being rotatably connected to the base 200. Providing support lugs 312 helps reduce the overall volume of the motor mounting base 310 and simplifies the structure of the tilting device 100. Furthermore, the plurality of support lugs 312 provides more connection structures for the mounting base body 311 to the base 200, allowing the mounting base body 311 to rotate more smoothly. The numerous connection structures also allow the base 200 to distribute more force to the output shaft 510 of the tilting motor 500, reducing the force on the output shaft 510 of the tilting motor 500 and improving the service life of the tilting motor 500.

[0054] Optionally, in one embodiment, the motor mounting base 310 further includes a connecting portion 313 connected to the mounting base body 311. The connecting portion 313 is disposed between the two support lugs 312 and is rotatably connected to the first end 321. The connecting portion 313 provides a mounting position for the first end 321, facilitating the installation of the first end 321.

[0055] Optionally, in one embodiment, the tilting device 100 further includes a second support 700 disposed on the base 200, through which the output shaft 510 rotatably passes. Thus, the second support 700 provides support for the output shaft 510, transmitting the force on the output shaft 510 to the base 200. In other words, the second support 700 shares the force on the output shaft 510, thereby improving the service life of the tilting motor 500.

[0056] Optionally, in one embodiment, multiple second support bases 700 are provided. Providing multiple second support bases 700 further provides better support for the output shaft 510, improving the structural stability of the tilting device 100 and facilitating the transfer of more force to the base 200, thus extending the service life of the tilting motor 500. Furthermore, the rocker arm 330 is positioned between two second support bases 700, which helps ensure smooth operation of the tilting device 100.

[0057] Optionally, in one embodiment, the motor mounting base 310 is located on one side of the base 200, and the tilting motor 500 is located on the opposite side of the base 200. This makes fuller use of the mounting space of the base 200, resulting in a smaller length and width dimension of the tilting motor 500. Of course, in other embodiments, both the motor mounting base 310 and the tilting motor 500 are located on the same side of the base 200.

[0058] Optionally, in one embodiment, the tilting device 100 further includes a limiting shell 800 disposed on the base 200, and the tilting motor 500 is partially disposed within the limiting shell 800. The limiting shell 800 can prevent the tilting motor 500 from detaching from the base 200, which is beneficial to the stable installation of the tilting motor 500. The limiting shell 800 is provided with weight reduction holes 810. In this way, it is beneficial to reduce the overall weight of the tilting motor 500.

[0059] Optionally, in one embodiment, multiple weight-reducing holes 810 are provided, and one weight-reducing hole 810 is configured as a heat dissipation hole. This can prevent the tilting motor 500 from overheating and enable the tilting motor 500 to maintain high performance for a longer period of time during operation.

[0060] Optionally, in one embodiment, multiple weight-reducing holes 810 are provided, and one weight-reducing hole 810 is configured as a wire passage hole, so as to facilitate the wire harness of the tilt motor 500 to pass through.

[0061] Optionally, in one embodiment, the base 200 is provided with a mounting groove, and the tilting device 100 further includes a connector 910 installed in the mounting groove and a pressing member 920 pressing the connector 910 against the bottom of the mounting groove. The pressing member 920 is provided on the base 200. The connector 910 is used to connect to the aircraft body of the aircraft. The connector 910 is stably connected to the base 200 under the clamping of the bottom of the mounting groove and the pressing member 920. The mounting groove restricts the connector 910 from swinging along the width direction of the mounting groove, which is beneficial to the relative stability of the connector 910 and the base 200. Of course, in other embodiments, the connector 910 and the base 200 are connected by a snap-fit.

[0062] Optionally, in one embodiment, in the width direction of the mounting groove, the connector 910 is located between the opposite ends of the pressing member 920. The opposite ends of the connector 910 are respectively connected to the base 200 by screws. During the process of tightening the screws, the pressing member 920 presses the connector 910 against the bottom of the mounting groove, thereby achieving a stable connection between the connector 910 and the base 200.

[0063] Optionally, in one embodiment, in a first state, the fourth end 332 is located between the first end 321 and the second end 322; in a second state, the second end 322 is located between the first end 321 and the fourth end 332. Without loss of generality, when the tilting device 100 is applied to an aircraft, in the first state, the rotation axis of the propeller, driven by the propeller motor 400, extends along the longitudinal direction of the aircraft, thereby providing power for level flight; in the second state, the rotation axis extends along the vertical direction of the aircraft, thereby providing power for vertical takeoff and landing. Of course, in other embodiments, in the first state, the second end 322 is located between the first end 321 and the fourth end 332; in the second state, the fourth end 332 is located between the first end 321 and the second end 322.

[0064] Optionally, in one embodiment, the tilt motor 500 is configured as a tilt servo, which is relatively small and facilitates the miniaturization of the tilt device 100. Of course, in other embodiments, the tilt motor 500 can also be configured as other types of tilt motors 500 according to actual needs, and there are no restrictions here.

[0065] Specifically, in one embodiment, the servo motor includes a servo motor body and an output shaft 510 connected to the servo motor body. The output shaft 510 includes an output shaft 510 body connected to the servo motor body, a servo disk connected to the output shaft 510 body, and a adapter shaft connected to the servo disk. The adapter shaft is used to drive the fourth end 332.

[0066] The present invention also proposes an aircraft, which includes an aircraft body, a propeller, and the aforementioned tilting device 100. The specific structure of the tilting device 100 is as described in the above embodiments. Since this aircraft adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The base 200 of the tilting device 100 is located on the aircraft body, and the propeller is drivenly connected to the propeller motor 400 of the tilting device 100.

[0067] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
