Technical Field

[0046] It should be noted that the term "multiple" means two or more, unless otherwise explicitly specified.
[0047] Please refer to the following: Figures 1 to 18 The inverted T-shaped probe provided by the present invention will now be described. The inverted T-shaped probe includes: a rotating damper 5, a boom 2, a foldable T-shaped frame 1, a suspension release mechanism 6, and an elastic mechanism F; the elastic mechanism F is mounted on the foldable T-shaped frame 1 and is used to unfold the foldable T-shaped frame 1; the two ends of the boom 2 are a first end 21 and a second end 22, respectively; the rotating damper 5 is mounted on the first end 21; the rotating damper 5 is used to mount the aircraft 4; the boom 2 can be rotatably connected to the aircraft 4 via the rotating damper 5; the foldable T-shaped frame 1 is rotatably mounted on the second end 22; the suspension release mechanism 6 is used to mount the aircraft 4; when the foldable T-shaped frame 1 is folded, the suspension release mechanism 6 can bind, suspend, or release the foldable T-shaped frame 1; the foldable T-shaped frame 1 has a placement position for placing a sensor 91; when the suspension release mechanism 6 releases the foldable T-shaped frame 1, the foldable T-shaped frame 1 unfolds into an inverted T-shape under the cooperation of gravity and / or the elastic mechanism F.
[0048] Thus, the two ends of the boom 2 are a first end 21 and a second end 22, respectively; the rotating damper 5 is used to install it onto the aircraft 4, and the first end 21 of the boom 2 is rotatably connected to the aircraft 4 through the rotating damper 5; when the external force is removed from the boom 2, the boom 2 can be vertically suspended below the aircraft 4; a foldable T-shaped frame 1 is suspended on the second end 22 of the boom 2, and the boom 2 and the foldable T-shaped frame 1 can rotate relative to each other, that is, the boom 2 and the foldable T-shaped frame 1 can be folded and unfolded to reduce the volume; the foldable T-shaped frame 1 can be folded by the user; the suspension release mechanism 6 is used to install it onto the aircraft 4, and when the user folds the foldable T-shaped frame 1... After folding, the user can use the sling release mechanism 6 to bundle and suspend the folded foldable T-frame 1 under the aircraft 4, saving space occupied by the foldable T-frame 1 and facilitating the takeoff of the aircraft 4; when the sling release mechanism 6 releases the folded foldable T-frame 1, the foldable T-frame 1 is freely suspended on the second end 22 of the boom 2; after being released by the sling release mechanism 6, the foldable T-frame 1 can unfold into an inverted T-shape under the cooperation of gravity (and / or the cooperation of the elastic mechanism F); the foldable T-frame 1 has a placement position for the sensor 91, which makes it convenient for the user to install the sensor 91 in the placement position for detection.
[0049] In addition, the rotating damper 5 is installed at the first end 21 of the boom 2 and is used to connect with the aircraft 4. The rotating damper 5 absorbs and attenuates the transient torque generated by the vibration or sudden maneuver of the aircraft 4 through rotation, thereby ensuring that the foldable T-frame 1 suspended at the second end 22 maintains a stable relative position during the flight phase.
[0050] In addition, the foldable T-frame 1 adopts a multi-bar hinge structure, which can be compactly folded along the axis of the suspending rod 2 in the bundled state of the suspension release mechanism 6, significantly reducing the volume envelope of the aircraft 4 during ground transportation, take-off and landing and standby, avoiding interference with other parts of the aircraft 4, and reducing the time cost of assembly and disassembly.
[0051] In addition, the suspension release mechanism 6 releases the constraint on the foldable T-shaped frame 1 after the aircraft 4 reaches the predetermined working position, so that the constrained foldable T-shaped frame 1 naturally swings down and unfolds into an inverted T shape under the cooperation of gravity, without the need for additional power drive, which simplifies the control logic and reduces the probability of failure; this gravity unfolding method can also use inertia to ensure that the unfolding is in place, providing initial accuracy for subsequent attitude maintenance.
[0052] In one embodiment, the placement location is an installation area or installation space on the surface of the foldable T-shaped frame 1.
[0053] In one embodiment, the rotary damper 5 has two degrees of freedom of rotation. In one embodiment, one degree of freedom of the rotary damper 5 is rotation about the X axis 54, and the other degree of freedom of the rotary damper 5 is rotation about the Y axis 56. X and Y are respectively set horizontally and are perpendicular to each other.
[0054] In one embodiment, the foldable T-shaped frame 1 can be folded manually by the user.
[0055] In an additional extended embodiment, the foldable T-shaped frame 1 is an elastic element; the foldable T-shaped frame 1 can be folded and unfolded; the hanging release mechanism 6 can bind the folded foldable T-shaped frame 1; when the hanging release mechanism 6 releases the foldable T-shaped frame 1, the foldable T-shaped frame 1 can unfold into an inverted T shape under its own elastic force.
[0056] In one embodiment, when the suspension release mechanism 6 releases the foldable T-shaped frame 1 and the T-shaped frame unfolds into a T-shape, the suspension rod 2 and the third rod 13 are coaxially arranged, and the center of gravity of the foldable T-shaped frame 1 is located on the axis of the suspension rod 2 below the suspension rod 2.
[0057] In one embodiment, if the foldable T-shaped frame 1 is freely suspended on the hanging rod 2, the hanging rod 2 is vertically positioned, and the center of gravity of the foldable T-shaped frame 1 is located on the axis of the hanging rod 2 below the hanging rod 2.
[0058] In one embodiment, the first rod 11, the second rod 12, the third rod 13, and the hanging rod 2 are all cylindrical rods.
[0059] In one embodiment, when the first rod 11 rotates to the first unfolding angle, the second rod 12 rotates to the second unfolding angle; the first rod 11 and the second rod 12 are coaxially arranged, and the third rod 13 is perpendicular to the first rod 11.
[0060] In one embodiment, the first rod 11 is located on one side of the third rod 13, and the second rod 12 is located on the other side of the third rod 13.
[0061] In one embodiment, a placement position is provided on the first rod 11. In one embodiment, a placement position is provided on the second rod 12. In one embodiment, a placement position is provided on the third rod 13.
[0062] In one embodiment, aircraft 4 is a quadcopter drone.
[0063] In one embodiment, the elastic mechanism F can be any one of a spring pin, a spring sheet, or a spring. In one embodiment, the elastic mechanism F can drive the first rod 11 to rotate from a first closing angle to a first unfolding angle. In one embodiment, the elastic mechanism F connects the first rod 11 and the third rod 13. In one embodiment, the elastic mechanism F can drive the second rod 12 to rotate from a second closing angle to a second unfolding angle. In one embodiment, the elastic mechanism F connects the second rod 12 and the third rod 13.
[0064] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, the foldable T-shaped frame 1 includes: a first rod 11, a second rod 12, a third rod 13, a first rotating shaft 14, a second rotating shaft 15, and a third rotating shaft 16; the two ends of the third rod 13 are a third end 131 and a fourth end 132, respectively; one end of the first rod 11 is rotatably mounted on the fourth end 132 around the first rotating shaft 14, and one end of the second rod 12 is rotatably mounted on the fourth end 132 around the second rotating shaft 15; the first rotating shaft 14 and the second rotating shaft 15 are arranged parallel to each other, and the first rotating shaft 14 and the second rotating shaft 15 are respectively aligned with... The third rod 13 is vertically arranged; the third end 131 is rotatably arranged on the second end 22 around the third pivot 16; the first rod 11 can rotate relative to the third rod 13 between a first closing angle and a first unfolding angle, and the second rod 12 can rotate relative to the third rod 13 between a second closing angle and a second unfolding angle; when the first rod 11 rotates to the first unfolding angle and the second rod 12 rotates to the second unfolding angle, the first rod 11, the second rod 12 and the third rod 13 are combined to form an inverted T-shape; the first rod 11 and / or the second rod 12 have a placement position for placing the sensor 91. Thus, as the first rod 11 rotates from the first unfolding angle to the first closing angle, the angle between the first rod 11 and the third rod 13 gradually decreases; as the first rod 11 rotates from the first closing angle to the first unfolding angle, the angle between the first rod 11 and the third rod 13 gradually increases to a perpendicular state; as the second rod 12 rotates from the second unfolding angle to the second closing angle, the angle between the second rod 12 and the third rod 13 gradually decreases; as the second rod 12 rotates from the second closing angle to the second unfolding angle, the angle between the second rod 12 and the third rod 13 gradually increases to a perpendicular state; when the third rod 13 rotates relative to the lifting rod 2 around the third pivot 16, the third rod 13 and the lifting rod 2 can be folded or unfolded together.
[0065] In addition, one end of the first rod 11 is rotatably mounted on the fourth end 132 around the first pivot 14, and one end of the second rod 12 is rotatably mounted on the fourth end 132 around the second pivot 15. The first pivot 14 and the second pivot 15 are parallel to each other and perpendicular to the third rod 13. The two rods can easily maintain mirror synchronization during the closing or unfolding process, avoiding an unbalanced state.
[0066] In addition, the third end 131 is rotatably mounted on the second end 22 around the third pivot 16, and the third pivot 16 is perpendicular to the first pivot 14 and the second pivot 15 respectively, so that the third rod 13 will not be affected by the rotation of the first rod 11 or the second rod 12 during the folding or unfolding process relative to the lifting rod 2.
[0067] In addition, when the first rod 11 and the second rod 12 are at the first deployment angle and the second deployment angle respectively, the first rod 11, the second rod 12 and the third rod 13 combine to form a horizontally symmetrical T-shape. The first rod 11 and the second rod 12 together form the horizontal part, and the third rod 13 (and / or the hanging rod 2) has the same direction to form the vertical part. The two placement positions are respectively set at the free ends of the first rod 11 and the second rod 12. The horizontal distance between the two placement positions is increased, which increases the distance between the sensors 91 and reduces the mutual interference between different sensors 91.
[0068] In addition, when the two rods are closed, the outer sides of the first rod 11 and the second rod 12 are attached to the side wall of the third rod 13, forming a stacked shape, which greatly reduces the folded volume and provides more freedom for the layout of the aircraft 4.
[0069] In one embodiment, when the first rod 11 rotates to the first closing angle, the first rod 11 and the third rod 13 are arranged in parallel.
[0070] In one embodiment, when the first rod 11 is rotated to the first unfolding angle, the first rod 11 and the third rod 13 are arranged perpendicularly.
[0071] In one embodiment, when the second rod 12 rotates to the second closing angle, the second rod 12 and the third rod 13 are arranged in parallel.
[0072] In one embodiment, when the second rod 12 rotates to the second unfolding angle, the second rod 12 and the third rod 13 are arranged perpendicularly.
[0073] In one embodiment, when the foldable T-shaped frame 1 is in a folded state, the first rod 11 rotates to a first closing angle, and the second rod 12 rotates to a second closing angle.
[0074] Further, please refer to Figures 1 to 18 In one specific embodiment of the inverted T-shaped probe provided by the present invention, the third rotating shaft 16 is perpendicular to the third rod 13, and the third rotating shaft 16 is perpendicular to the first rotating shaft 14 and the second rotating shaft 15 respectively. The orthogonality of the three rotating shafts (the third rod 13, the first rotating shaft 14 (or the second rotating shaft 15), and the third rotating shaft 16) ensures that the rotation planes of the first rod 11 and the second rod 12 do not intersect with the rotation plane of the third rod 13, thus avoiding the interference or locking phenomenon commonly seen in parallel rotating shafts.
[0075] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, the third rod 13 can rotate relative to the boom 2 between a third closing angle and a third unfolding angle; when the third rod 13 rotates to the third unfolding angle, the third rod 13 and the boom 2 are coaxially arranged. Thus, when the third rod 13 rotates to the third unfolding angle, the third rod 13 and the boom 2 are coaxial, forming a continuous longitudinal force transmission path. The self-weight and lateral load are directly transmitted to the aircraft 4 through the boom 2, reducing the eccentric bending moment and improving attitude stability; the coaxial support also enhances the overall stiffness and torsional resistance.
[0076] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, it further includes: a first sleeve 31, a second sleeve 32, and a third sleeve 33; the elastic mechanism F includes: a first elastic pin 34 and a second elastic pin 35; the first sleeve 31 is rotatably mounted on the third sleeve 33 via a first rotating shaft 14, and the second sleeve 32 is rotatably mounted on the third sleeve 33 via a second rotating shaft 15; one end of the first rod 11 is inserted into the first sleeve 31, one end of the second rod 12 is inserted into the second sleeve 32, and the fourth end 132 of the third rod 13 is inserted into the third sleeve 33; the first elastic pin 34 is disposed on the outer surface of the first sleeve 31, and when the first rod 11 rotates to the first closing angle, the first sleeve 31 and the third sleeve 33 clamp and compress the first elastic pin 34; the second elastic pin 35 is disposed on the outer surface of the second sleeve 32, and when the second rod 12 rotates to the second closing angle, the second sleeve 32 and the third sleeve 33 clamp and compress the second elastic pin 35. Thus, when the first rod 11 rotates to the first closing angle, the suspension release mechanism 6 can maintain the first rod 11 in the closed state. At this time, the first sleeve 31 and the third sleeve 33 clamp and compress the first elastic pin 34. When the suspension release mechanism 6 releases the restraint on the first rod 11 and the third rod 13, the first elastic pin 34 can push the first sleeve 31 and the third sleeve 33 apart to facilitate the opening of the first rod 11 and the third rod 13. When the second rod 12 rotates to the second closing angle, the suspension release mechanism 6 can maintain the second rod 12 in the closed state. At this time, the second sleeve 32 and the third sleeve 33 clamp and compress the second elastic pin 35. When the suspension release mechanism 6 releases the restraint on the second rod 12 and the third rod 13, the second elastic pin 35 can push the second sleeve 32 and the third sleeve 33 apart to facilitate the opening of the second rod 12 and the third rod 13.
[0077] In addition, when the first sleeve 31 and the third sleeve 33, and the second sleeve 32 and the third sleeve 33 are at the first closing angle and the second closing angle position, they press the first elastic pin 34 and the second elastic pin 35 together, so that the two elastic pins are compressed at the same time and store elastic potential energy.
[0078] In one embodiment, the first elastic pin 34 can push the first rod 11 from a first closing angle to a first unfolding angle.
[0079] In one embodiment, the second resilient pin 35 can push the second rod 12 from the second closing angle to the second unfolding angle.
[0080] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, it also includes: a first limiting mechanism and a second limiting mechanism.
[0081] In one embodiment, the first limiting mechanism includes: a first blind hole 71, a first spring 72, a first positioning pin 731, a first connecting portion 741, a first positioning hole 75, and a first button 761; the first blind hole 71 is formed on the outer surface of the first sleeve 31, the first spring 72 is disposed in the first blind hole 71, the first positioning pin 731 is inserted into the first blind hole 71, and the first spring 72 is clamped between the bottom wall of the first blind hole 71 and the first positioning pin 731; the first rotating shaft 14 is disposed on the first connecting portion 741, and the first button 761 is disposed on the first connecting portion 741; the first positioning hole 75 is formed on the first connecting portion 741; when the first rod 11 rotates to the first unfolding angle, the first positioning pin 731 is inserted into the first positioning hole 75; when the first button 761 is pressed, the first button 761 can push the first positioning pin 731 out of the first positioning hole 75. Thus, when the first rod 11 rotates to the first unfolding angle, the first positioning pin 731 is inserted into the first positioning hole 75, thereby locking the first sleeve 31 and the third sleeve 33; when the first button 761 is pressed by the user, the first button 761 pushes the first positioning pin 731 away from the first positioning hole 75, thereby unlocking the first sleeve 31 and the third sleeve 33; after the first sleeve 31 and the third sleeve 33 are unlocked, the angle between the first rod 11 and the third rod 13 can be changed by the user.
[0082] In addition, when the first rod 11 rotates to the first unfolding angle, the first positioning pin 731 automatically enters the first positioning hole 75 after being guided by the first blind hole 71 under the thrust of the first spring 72, achieving instantaneous positioning; it can maintain the relative position of the first rod 11 and the third rod 13.
[0083] In addition, the first button 761 and the second button 762 are directly set on the outer surface of the first connecting part 741. The operator can push the first positioning pin 731 out of the corresponding first positioning hole 75 by pressing the button, and unlock the device without disassembling any parts, thus avoiding the need for additional tools and improving the convenience of on-site maintenance.
[0084] In one embodiment, the extension and retraction direction of the first positioning pin 731 is parallel to that of the first rotating shaft 14. In another embodiment, the first positioning pin 731 is parallel to the first rotating shaft 14.
[0085] In one embodiment, the first connecting portion 741 has a first abutting wall 7411; when the first rod 11 rotates from the first closing angle to the first unfolding angle, the first abutting wall 7411 is located on the rotation path of the first sleeve 31. Thus, the first abutting wall 7411 can limit the rotation of the first rod 11.
[0086] In one embodiment, the second connecting portion 742 has a second abutting wall; when the second rod 11 rotates from the second closing angle to the second unfolding angle, the second abutting wall is located on the rotation path of the second sleeve 32. Thus, the second abutting wall can limit the rotation of the second rod 12.
[0087] In one embodiment, the second limiting mechanism includes: a second blind hole, a second spring, a second positioning pin, a second connecting portion 742, a second positioning hole, and a second button 762; the second blind hole is formed on the outer surface of the second sleeve 32, the second spring is disposed in the second blind hole, the second positioning pin is inserted into the second blind hole, and the second spring is clamped between the bottom wall of the second blind hole and the second positioning pin; the second rotating shaft 15 is disposed on the second connecting portion 742, and the second button 762 is disposed on the second connecting portion 742; the second positioning hole is formed on the second connecting portion 742; when the second rod 12 rotates to the second unfolding angle, the second positioning pin is inserted into the second positioning hole; when the second button 762 is pressed, the second button 762 can push the second positioning pin out of the second positioning hole. Thus, when the second rod 12 rotates to the second unfolding angle, the second positioning pin is inserted into the second positioning hole, thereby locking the second sleeve 32 and the third sleeve 33; when the second button 762 is pressed by the user, the second button 762 pushes the second positioning pin away from the second positioning hole, thereby unlocking the second sleeve 32 and the third sleeve 33; after the second sleeve 32 and the third sleeve 33 are unlocked, the angle between the second rod 12 and the third rod 13 can be folded by the user.
[0088] In addition, when the second rod 12 rotates to the second unfolding angle, the second positioning pin automatically enters the second positioning hole after being guided by the second blind hole under the action of the second spring, achieving instantaneous positioning; it can maintain the relative position of the second rod 12 and the third rod 13.
[0089] In addition, the second button 762 is directly set on the outer surface of the second connecting part 742. The operator can press the button to push the second positioning pin out of the corresponding second positioning hole, and unlock the device without disassembling any parts, thus avoiding the need for additional tools and improving the convenience of on-site maintenance.
[0090] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, it further includes: a locking mechanism 8; when the third rod 13 rotates to the third unfolding angle, the locking mechanism 8 can lock the lifting rod 2 and the third rod 13; and / or when the third rod 13 rotates to the third closing angle, the third rod 13 and the lifting rod 2 are arranged in parallel. Thus, when the third rod 13 rotates to the third unfolding angle, the locking mechanism 8 can lock the lifting rod 2 and the third rod 13, thereby maintaining the relative positions of the lifting rod 2 and the third rod 13.
[0091] In one embodiment, when the third rod 13 rotates to the third unfolding angle, the lifting rod 2 and the third rod 13 are coaxially arranged.
[0092] In one embodiment, when the third rod 13 rotates to the third unfolding angle, the end face of the second end 22 and the end face of the third end 131 abut against each other. In this way, the relative position of the suspension rod 2 and the third rod 13 can be kept stable after the end faces of the second end 22 and the third end 131 abut against each other.
[0093] Further, please refer to Figures 1 to 18 As a specific embodiment of the inverted T-shaped probe provided by the present invention, the locking mechanism 8 includes: a hook body 81 and a hook portion 82; the hook body 81 is disposed on the lifting rod 2, and the hook portion 82 is disposed on the fourth end 132; when the third rod 13 rotates to the third unfolding angle, the hook body 81 hooks the hook portion 82. When the third rod 13 rotates to the third unfolding angle, the hook body 81 and the hook portion 82 cooperate to lock the lifting rod 2 and the third rod 13.
[0094] In one embodiment, a user can disengage the hook body 81 and the hook portion 82 by moving the hook body 81.
[0095] Further, please refer to Figures 1 to 18As a specific embodiment of the inverted T-shaped probe provided by the present invention, the suspension release mechanism 6 includes: a rope 61 and a release device 62; the release device 62 is used to be mounted on the aircraft 4; one end of the rope 61 is connected to the aircraft 4, and the other end of the rope 61 is connected to the release device 62; when the first rod 11 rotates to the first closing angle, the second rod 12 rotates to the second closing angle, and the third rod 13 rotates to the third closing angle, the rope 61 is bundled to the outside of the first rod 11, the second rod 12, and the third rod 13; the release device 62 can release the rope 61. In this way, the rope 61 can bundle and suspend the folded foldable T-shaped frame 1; one end of the rope 61 can be connected to the aircraft 4, and the other end of the rope 61 is connected to the release device 62, which can release the other end of the rope 61; when the other end of the rope 61 is released, the bundled foldable T-shaped frame 1 can be released.
[0096] In one embodiment, the releaser 62 can be any one of a servo motor for releasing the rope 61, a clamping cylinder, or an electric gripper.
[0097] Furthermore, when the first rod 11, the second rod 12, and the third rod 13 are located at the first closing angle, the second closing angle, and the third closing angle, respectively, the rope 61 can be firmly bound to the outside of the three rods, achieving multi-point encircling constraint. Since the rope 61 forms a continuous wrap around the outer surface of the three rods, its tensile stiffness is converted into radial tightening force under the vibration or sudden acceleration environment of the aircraft 4, thereby maintaining the compactness of the folded state and preventing relative displacement of the first rod 11, the second rod 12, or the third rod 13 due to inertial swaying, ensuring the safety of the structure during air transport and high-speed maneuvering.
[0098] In addition, the rope 61 can be quickly released by the release device 62. The action of the release device 62 does not require applying additional torque to the three rods. Simply releasing the constraint of the rope 61 will instantly remove the binding conditions of the folded state. Subsequently, the first rod 11, the second rod 12, and the third rod 13 unfold in sequence under the cooperation of their respective hinge points and gravity. This avoids complex motor or pneumatic drives, improves the reliability of the system, and reduces energy consumption.
[0099] In addition, the rope 61 is placed outside the first rod 11, the second rod 12, and the third rod 13, so it will not interfere with the internal rotating space.
[0100] Further, please refer to Figures 1 to 18As a specific embodiment of the inverted T-shaped probe provided by the present invention, the rotating damper 5 includes: a base 51, a snap-fit mechanism 52, a mounting base 53, an X-axis 54, a connecting base 55, a Y-axis 56, a first damping mechanism, and a second damping mechanism; the base 51 is used to fix it on the aircraft 4, and the mounting base 53 is detachably fixed to the base 51 through the snap-fit mechanism 52; the connecting base 55 is rotatably connected to the mounting base 53 through the X-axis 54, and the first damping mechanism connects the connecting base 55 and the mounting base 53; the first end 21 is rotatably mounted on the connecting base 55 through the Y-axis 56, and the second damping mechanism connects the first end 21 and the connecting base 55. Thus, the base 51 can be installed on the aircraft 4, and the mounting seat 53 can be installed on the base 51 through the snap-fit mechanism 52; the connecting seat 55 and the mounting seat 53 can rotate relative to each other around the X-axis 54, and the first damping mechanism can generate a damping effect when the connecting seat 55 and the mounting seat 53 rotate relative to each other; the first end 21 and the connecting seat 55 can rotate relative to each other around the Y-axis 56, and the second damping mechanism can generate a damping effect when the first end 21 and the connecting seat 55 rotate relative to each other.
[0101] In addition, the base 51 is fixed on the aircraft 4, providing a rigid mounting interface for the entire set of rotating dampers 5; the mounting seat 53 is detachably fixed to the base 51 through the snap-fit mechanism 52, so that the mounting seat 53 and the aircraft 4 form a connection that can be quickly separated. When maintaining or replacing the first damping mechanism and the second damping mechanism, the mounting seat 53 and downstream components can be removed as a whole simply by loosening the snap-fit mechanism 52, which greatly shortens the maintenance process and reduces ground downtime.
[0102] In addition, the connecting seat 55 is rotatably connected to the mounting seat 53 via the X-axis 54, which provides the first degree of rotational freedom; the first damping mechanism bridges the connecting seat 55 and the mounting seat 53, and applies an adjustable damping torque around the X-axis 54, which can suppress rapid swaying caused by the maneuvering of the aircraft 4 or external disturbances, and ensure a smooth transition of the rotation of the connecting seat 55.
[0103] In addition, the first end 21 is rotatably mounted on the connecting seat 55 via the Y-axis 56. The Y-axis 56 and the X-axis 54 form a multi-axis structure that is independent of each other but orthogonal or parallel, providing a second degree of freedom for the first end 21 (i.e., the first end 21 of the boom 2). The second damping mechanism connects the first end 21 and the connecting seat 55, applying damping in the circumferential direction of the Y-axis 56, so that the rotation of the first end 21 has a similar "soft speed limiting" characteristic.
[0104] In addition, the dual damping (first damping mechanism and second damping mechanism) enables the rotary damper 5 to attenuate vibration modes in different directions, thereby maintaining the dynamic stability of the end of the boom 2 in the complex aerodynamic environment of the aircraft 4 (such as gusts or rapid attitude adjustments), and effectively improving the overall measurement accuracy of the inverted T-shaped probe.
[0105] In addition, the detachable feature of the snap-fit mechanism 52 not only facilitates daily maintenance, but also allows for quick replacement of the first damping mechanism and the second damping mechanism with different parameters in different tasks, so as to achieve task-level adaptation of damping characteristics.
[0106] In one embodiment, the latching mechanism 52 includes a hook 522 and a hole 521; the hook 522 is disposed on the mounting base 53, and the hole 521 is disposed on the base 51. The hook 522 can be engaged in the hole 521 to connect the base 51 and the mounting base 53.
[0107] In one embodiment, the first damping mechanism cooperating with the X-axis 54 (or the second damping mechanism cooperating with the Y-axis 56) can be found in: (Chinese Utility Model Patent; Publication No.: CN202811809U; Subject: A Shaft with a Damping System; Publication Date: 2013-03-20).
[0108] In one embodiment, the first damping mechanism cooperating with the X-axis 54 (or the second damping mechanism cooperating with the Y-axis 56) can be found in: (Chinese Utility Model Patent; Publication No.: CN222185450U; Subject: A Rotating Shaft Damping Mechanism and Screen Base; Publication Date: 2024-12-17).
[0109] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
