Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a center of gravity switching mechanism and an unmanned aerial vehicle. Background Art

[0002] The drone used for capture mainly includes the drone body and the load transmitter (such as the net gun load). During the flight of the drone, after the load transmitter is launched, the weight of the drone is reduced, causing the center of gravity of the drone to change, thus causing the drone's flight attitude to lose control. At present, drones mainly overcome the torque caused by the center of gravity offset by adding a large torque motor, but adding a large torque motor increases the overall weight of the drone and cannot directly solve the center of gravity offset caused by the change in weight of the drone. Summary of the invention

[0003] Based on this, it is necessary to provide a center of gravity switching mechanism and a UAV to address the above problems. The center of gravity switching mechanism reduces the overall weight of the UAV, adjusts the center of gravity position of the UAV, and achieves a stable flight attitude of the UAV.

[0004] The present invention provides a center of gravity switching mechanism for mounting a load transmitter on a drone body to form a drone, comprising:

[0005] A mounting assembly for being arranged on the main body of the drone, comprising a mounting seat and a limiting member movably arranged on the mounting seat;

[0006] A sliding assembly for being arranged on the load transmitter, the sliding assembly slidably cooperates with the mounting assembly, the sliding assembly is provided with a first limiting groove for limiting the limiting member, a second limiting groove for limiting the limiting member, and a first guide groove connecting the first limiting groove and the second limiting groove; the first guide groove is used to guide the limiting member to slide from the first limiting groove into the second limiting groove; and

[0007] a reset assembly, the reset assembly being disposed between the mounting assembly and the sliding assembly and being used to apply a reset force to the sliding assembly relative to the mounting assembly;

[0008] The sliding assembly is driven by the reaction force generated by the load transmitter when transmitting the load to slide relative to the mounting assembly, so that the limiting member slides from the first limiting groove into the first guide groove; the limiting member slides from the first guide groove into the second limiting groove under the action of the resetting assembly, so as to keep the center of gravity position of the drone unchanged before and after the load is launched.

[0009] With such a configuration, after the load transmitter is launched, the weight is reduced, causing the center of gravity of the drone to shift, making it difficult to ensure the stable flight of the drone. The unstable flight attitude of the drone caused by the weight change is solved by adding a center of gravity switching mechanism. Among them, the load transmitter generates a reaction force after launching, pushing the sliding assembly to slide relative to the mounting assembly, connecting the first limit groove with the first guide groove, and making the limiter slide from the first limit groove into the first guide groove. At this time, the center of gravity of the drone changes, and the first guide groove is connected with the second limit groove. The reset assembly slides the limiter from the first guide groove into the second limit groove, and the center of gravity of the drone is adjusted to the motor axis.

[0010] In one embodiment of the present invention, the sliding assembly is further provided with a second guide groove connecting the second limiting groove and the first limiting groove, and the second guide groove is used to guide the limiting member to slide from the second limiting groove into the first limiting groove.

[0011] With this arrangement, when the load transmitter is launched again, the weight of the UAV increases and the center of gravity of the UAV changes. It is necessary to adjust the position of the sliding assembly, connect the second guide groove to the second limit groove and the first limit groove, and manually slide the limit piece from the second limit groove into the first limit groove to adjust the center of gravity of the UAV to the motor axis.

[0012] In one embodiment of the present invention, the first limiting groove has a first slide-in end connected to the second guide groove and a first slide-out end connected to the first guide groove, and the first slide-in end and the first slide-out end both extend obliquely in a direction away from the second limiting groove;

[0013] The second limiting groove has a second slide-in end and a second slide-out end extending obliquely toward a direction close to the first limiting groove, the second slide-out end is connected to the second guide groove, and the second slide-in end is connected to the first guide groove.

[0014] With such arrangement, when adjusting the position of the center of gravity switching mechanism, it is difficult for the limit member to ensure one-way sliding between the first limit slot and the second limit slot. When the load transmitter is launched, the limit member is slid into the first limit slot, and the first sliding-in end and the first sliding-out end are both tilted and extended in a direction away from the second limit slot, limiting the limit member from sliding back from the first limit slot to the second guide slot. After the load transmitter is launched, the reset assembly slides the limit member from the first guide slot into the second limit slot, and the second sliding-in end and the second sliding-out end are both tilted and extended in a direction close to the first limit slot, limiting the limit member from sliding back from the second limit slot to the first guide slot.

[0015] In one embodiment of the present invention, the groove bottom of the second slide-in end is higher than the groove bottom of the second slide-out end.

[0016] With this arrangement, the center of gravity of the drone shifts after the load transmitter is launched, and the reset assembly needs to slide the limit member from the first guide groove into the second limit groove, and limit the limit member at the second slide-out end adjacent to the second slide-in end to prevent the limit member from sliding back to the first guide groove.

[0017] In one embodiment of the present invention, a groove bottom of the second guide groove adjacent to the first slide-in end is higher than a groove bottom of the first slide-in end.

[0018] With such arrangement, when the load transmitter is transmitting, the limit member is manually slid from the second limit slot into the first limit slot, and the limit member is first slid in and restricted to the first sliding end adjacent to the second guide slot to prevent the limit member from sliding back to the second limit slot after being manually released.

[0019] In one embodiment of the present invention, the groove bottom of the first slide-in end is higher than the groove bottom of the first slide-out end.

[0020] With such arrangement, when the load transmitter is launched, the limiting member slides in and is restricted to the first sliding-out end adjacent to the first sliding-in end, thereby preventing the limiting member from sliding back to the second guide groove.

[0021] In one embodiment of the present invention, the groove bottom of the first slide-out end is higher than the groove bottom of the first guide groove adjacent to the first slide-out end.

[0022] With such arrangement, after the load transmitter is launched, the reaction force causes the limiting member to slide from the first limiting groove into the first guide groove adjacent to the first slide-out end, thereby preventing the limiting member from sliding back to the first limiting groove.

[0023] In one embodiment of the present invention, the depth of the first guide groove from the first slide-out end to the second slide-in end close to the second slide-out end gradually decreases, and the depth of the groove from the second slide-out end to the second slide-in end close to the first slide-out end close to the first guide groove gradually increases.

[0024] With such arrangement, after the load transmitter is launched, the limit member slides from the first limit slot into the first guide slot, the center of gravity of the drone shifts, and the limit member is slid into the second limit slot through the reset assembly to prevent the limit member from sliding directly from the first guide slot into the second limit slot under the reaction force. In addition, the limit member is manually slid from the second limit slot into the first sliding end to prevent the limit member from sliding back to the second limit slot after being manually released.

[0025] In one embodiment of the present invention, the mounting seat is provided with a sliding groove extending along a direction perpendicular to the sliding direction of the sliding assembly, and the limiting member is slidably disposed in the sliding groove.

[0026] With such arrangement, when adjusting the position of the center of gravity switching mechanism, the limit member needs to slide in the direction perpendicular to the load launch, and the limit member is arranged in the sliding groove, so that when the center of gravity of the drone is switched, one end of the limit member slides in the sliding groove, and the other end slides in the first limit groove, the second limit groove and the first guide groove, and the second guide groove.

[0027] In one embodiment of the present invention, the limiting member also includes a slider, a limiting column and a biasing member. The slider can be slidably installed in the sliding groove. The biasing member is arranged between the limiting column and the slider, and is used to bias the limiting column toward the sliding assembly so that the limiting column always rests against the bottom of the first limiting groove, the second limiting groove and the first guide groove.

[0028] With such arrangement, the depths of the first limit groove, the second limit groove and the first guide groove and the second guide groove are different, and the limit member needs to expand and contract the upper and lower distances when sliding. The limit column is biased by the biasing member so that the limit column is always pressed against the bottom of the first limit groove, the second limit groove and the first guide groove.

[0029] The present invention also provides a drone, comprising a drone body; a load transmitter; and any of the above-mentioned center of gravity switching mechanisms, wherein the center of gravity switching mechanism installs the load transmitter on the drone body.

[0030] Compared with the prior art, the center of gravity switching mechanism provided by the present invention changes the center of gravity position of the UAV by setting a limit member to slide in the limit groove and the guide groove, so as to adjust the center of gravity position of the UAV after the load transmitter is launched to ensure the stable flight of the UAV.

[0042] The present invention provides a center of gravity switching mechanism, which is used to install a load transmitter on an unmanned aerial vehicle (UAV) body to form an unmanned aerial vehicle (UAV). The mechanism can solve the problem of flight attitude failure caused by the change of center of gravity after the unmanned aerial vehicle (UAV) load transmitter is launched, and achieve flight attitude stability by adjusting the center of gravity of the unmanned aerial vehicle.

[0043] refer to Figures 1 to 7As shown, the gravity switching mechanism is used to install the load transmitter 40 on the drone body to form a drone. The gravity switching mechanism includes a mounting assembly 10, a sliding assembly 20 and a reset assembly 30. The mounting assembly 10 is arranged on the drone body, and the sliding assembly 20 is arranged on the load transmitter 40. The gravity center of the drone is adjusted by slidingly cooperating between the sliding assembly 20 and the mounting assembly 10. The mounting assembly 10 includes a mounting seat 11 and a limiting member 12. The limiting member 12 can be movably arranged on the mounting seat 11 to adjust the gravity center of the drone. The sliding assembly 20 is provided with a first limiting groove 21 and a second limiting groove 22, which are used to limit the limiting member 12, so that the position of the limiting member 12 can be adjusted in time when the center of gravity is switched; in addition, the sliding assembly 20 is provided with a first guide groove 23 and a second guide groove 24, the first guide groove 23 connects the first limiting groove 21 and the second limiting groove 22, so that the limiting member 12 slides from the first limiting groove 21 into the second limiting groove 22, and the second guide groove 24 connects the first limiting groove 21 and the second limiting groove 22, so that the limiting member 12 slides from the second limiting groove 22 into the first limiting groove 21.

[0044] Specifically, Figures 2 to 6 As shown, the load transmitter 40 generates a reaction force after launch, driving the sliding assembly 20 to slide relative to the mounting assembly 10, so that the limit member 12 slides from the first limit groove 21 into the first guide groove 23. The reset assembly 30 is arranged between the mounting assembly 10 and the sliding assembly 20, and is used to apply a reset force to the sliding assembly 20 relative to the mounting assembly 10, so that the limit member 12 slides from the first guide groove 23 into the second limit groove 22 under the action of the reset assembly 30, thereby ensuring that the center of gravity position of the UAV remains unchanged before and after the load launch, thereby achieving stable flight of the UAV.

[0045] Preferably, if Figure 2 and Figure 3 As shown, the reset assembly 30 includes a spring 31, a first hook 32 and a second hook 33, wherein the first hook 32 is fixed to one end of the mounting assembly 10, and the second hook 33 is fixed to an end of the sliding assembly 20 in the opposite direction to the first hook 32, and the spring 31 is connected to the first hook 32 and the second hook 33, so that the mounting assembly 10 and the sliding assembly 20 can be slidably matched through the extension and retraction of the spring 31.

[0046] refer to Figures 2 to 7As shown, when the mounting assembly 10 and the sliding assembly 20 are slidably matched, the limit member 12 slides unidirectionally on the sliding assembly 20. Specifically, when the load transmitter 40 is launched, a reaction force is generated, driving the limit member 12 to slide, so that the limit member 12 slides from the first limit groove 21 into the first guide groove 23, and then a reset force is applied through the reset assembly 30 to introduce the limit member 12 from the first guide groove 23 into the second limit groove 22, so as to adjust the center of gravity of the UAV to the motor axis, so that the flight of the UAV is stable.

[0047] In one embodiment, if Figure 4 and Figure 7 As shown, the sliding assembly is provided with a second guide groove 24, and the second guide groove 24 is connected to the second limit groove 22 and the first limit groove 21, so as to manually guide the limit member 12 from the second limit groove 22 to the first limit groove 21 before the spring 31 pulls the load transmitter 40 to launch, so as to adjust the center of gravity of the drone to the motor axis.

[0048] Specifically, Figure 4 and Figure 7 As shown, the first limiting groove 21 has a first sliding-in end 211 and a first sliding-out end 212, the first sliding-in end 211 is connected to the second guide groove 24 to introduce the limiting member 12 from the second guide groove 24 into the first limiting groove 21, the first sliding-out end 212 is connected to the first guide groove 23 to introduce the limiting member 12 from the first limiting groove 21 into the first guide groove 23 under the reaction force after the load is launched, the first sliding-in end 211 and the first sliding-out end 212 both extend obliquely in a direction away from the second limiting groove 22, and the second guide groove 24 extends in the load launching direction, so that before the load transmitter 40 is launched, the limiting member 12 can be manually introduced from the second limiting groove 22 into the first limiting groove 21, so that the flight attitude of the UAV is stable when the load transmitter is at any angle.

[0049] In addition, if Figure 4 and Figure 7 As shown, the second limiting groove 22 has a second sliding-in end 221 and a second sliding-out end 222. The second sliding-in end 221 is connected to the first guide groove 23, so that when the reset assembly 30 applies a reset force, the limiting member 12 is introduced from the first guide groove 23 into the second limiting groove 22. The second sliding-out end 222 is connected to the second guide groove 24. The limiting member 12 slides from the second limiting groove 22 into the first limiting groove 21 under the action of the spring 31. The second sliding-in end 221 and the second sliding-out end 222 extend obliquely toward the direction close to the first limiting groove 21, so that the limiting member 12 can slide from the second limiting groove 22 into the first limiting groove 21 under manual force.

[0050] Preferably, the groove bottom of the second sliding-in end 221 is higher than the groove bottom of the second sliding-out end 222, so that a limiting step is formed at the connection between the second sliding-in end 221 and the second sliding-out end 222 of the second limiting groove 22, so as to apply a reset force to the reset assembly 30. Under the tensile action of the spring 31, the limiting member 12 slides from the first guide groove 23 into the limiting step of the second limiting groove 22 and will not slide back to the first guide groove 23.

[0051] Preferably, the bottom of the second guide groove 24 adjacent to the first sliding-in end 211 is higher than the bottom of the first sliding-in end 211, so that a limiting step is formed on the second guide groove 24 adjacent to the first sliding-in end 211, so that under manual action, the limiting member 12 can slide from the second limiting groove 22 into the limiting step on the second guide groove 24 adjacent to the first sliding-in end 211, and the limiting member 12 will not slide back to the second limiting groove 22.

[0052] Preferably, the groove bottom of the first sliding-in end 211 is higher than the groove bottom of the first sliding-out end 212, so that a limiting step is formed at the connection between the first sliding-in end 211 and the first sliding-out end 212 of the first limiting groove 21, so that before the load transmitter 40 is launched, the limiting member 12 is adjusted to the limit step formed at the connection between the first sliding-in end 211 and the first sliding-out end 212 of the first limiting groove 21, and the limiting member 12 will not slide back to the second guide groove 24.

[0053] Preferably, the groove bottom of the first slide-out end 212 is higher than the groove bottom of the first guide groove 23 adjacent to the first slide-out end 212, so that a limiting step is formed adjacent to the first slide-out end 212 and the first guide groove 23, so that after the load transmitter 40 is launched, the limiting member 12 slides from the first limiting groove 21 into the limiting step formed adjacent to the first slide-out end 212 and the first guide groove 23, and the limiting member 12 will not slide back to the first limiting groove 21.

[0054] More preferably, the depth of the first guide groove 23 from the first slide-out end 212 to the second slide-in end 221 to the second slide-out end 222 gradually decreases, so as to prevent the limiting member 12 from directly sliding into the second limiting groove 22 along the first guide groove 23 under the reaction force generated when the load transmitter 40 is launched. At this time, the limiting member 12 is slid from the first guide groove 23 into the second limiting groove 22 by the stretching action of the spring 31 in the reset assembly 30, so as to adjust the center of gravity of the UAV; in addition, the depth of the groove from the second slide-out end 222 to the second slide-in end 221 to the first slide-out end 212 to the first guide groove 23 gradually increases, so that the limiting member 12 slides from the second limiting groove 22 into the first limiting groove 21, so that the center of gravity of the UAV is on the motor axis, and the flight stability of the UAV at any angle is achieved.

[0055] In one embodiment, if Figure 5 and Figure 6As shown, the mounting seat 11 is provided with a sliding groove 111, and the sliding groove 111 extends along a sliding direction perpendicular to the sliding direction of the sliding assembly 20, and the limiting member 12 is slidably disposed in the sliding groove 111, so that the center of gravity of the UAV can be adjusted by sliding the limiting member 12 in the first limiting groove 21, the second limiting groove 22, the first guide groove 23 and the second guide groove 24, thereby achieving stable flight of the UAV.

[0056] Preferably, the length of the sliding groove 111 is greater than or equal to the vertical distance from the first guide groove 23 to the second guide groove 24, so that when the limit member 12 slides in the limit groove and the guide groove of the sliding assembly 20, the installation assembly 10 and the sliding assembly 20 will not slide in the direction perpendicular to the load emission direction.

[0057] In one embodiment, if Figure 5 and Figure 6 As shown, the limit member 12 also includes a slider 121, a limit column 122 and a biasing member 123, and the biasing member 123 is arranged between the limit column 122 and the slider 121, and the slider 121 can be slidably installed in the sliding groove 111, so that when the limit member 12 slides in the first limit groove 21, the second limit groove 22, the first guide groove 23 and the second guide groove 24, the biasing member 123 biases the limit column 122 toward the sliding assembly 20, so that the limit column 122 always rests on the bottom of the first limit groove 21, the second limit groove 22, the first guide groove 23 and the second guide groove 24.

[0058] Preferably, the biasing member 123 is a spring member, and the width of the slider 121 is greater than the width of the sliding groove 111 to prevent the slider 121 from sliding out of the sliding groove 111, but not limited to this. The limit member 12 can be a spring damper, which can also reduce the amplitude of the limit member 12 during the sliding process of the limit member 12.

[0059] In one embodiment, if Figure 4 and Figure 7 As shown, the sliding assembly 20 is provided with a guide rail 25 extending along the load emission direction, and the mounting assembly 10 is provided with a guide block 13, so that when the sliding assembly 20 and the mounting assembly 10 are slidably matched, the guide block 13 slides linearly on the guide rail 25, so that when the limiting member 12 slides in the first limiting groove 21, the second limiting groove 22, the first guide groove 23 and the second guide groove 24, the sliding position of the sliding assembly 20 and the mounting assembly 10 is stabilized to avoid biased sliding.

[0060] The present invention further provides a drone, comprising a drone body, a load transmitter 40 and the center of gravity switching mechanism described in the above embodiments, wherein the center of gravity switching mechanism installs the load transmitter 40 on the drone body.

[0061] The working principle of the center of gravity switching mechanism provided by the present invention is as follows: Figure 7As shown, first, when the load transmitter 40 is launched, a reaction force is generated, and the limit member 12 slides from the first limit groove 21 into the first guide groove 23. At this time, the reset assembly 30 applies a reset force, and the limit member 12 slides from the first guide groove 23 into the second limit groove 22. The load transmitter 40 is in the second limit groove 22 when not launched. By manual sliding, the upper limit member 12 of the installation assembly 10 slides from the second limit groove through the second guide groove 24 into the first limit groove 21, and the center of gravity of the UAV is adjusted to the motor axis, so that the center of gravity of the UAV remains unchanged before and after the load transmitter 40 is launched, thereby achieving stable flight of the UAV at any angle.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
