Abstract
Description
Technical Field
[0001] This invention relates to the field of drone nest technology, and in particular to a clutch-type flexible transmission drone nest door opening and closing mechanism and a drone nest. Background Technology
[0002] As the core infrastructure of unmanned aerial vehicle (UAV) automation systems, the application scenarios of UAV nests are rapidly expanding with the popularization of UAV technology. The opening and closing motion of the nest door is an important process for autonomous operation of UAVs. Existing products mainly use linkage-type opening and closing mechanisms, screw-driven and self-locking mechanisms, and gear and rack translation mechanisms to perform the door opening and closing actions.
[0003] The main technical problems with the existing technology are as follows:
[0004] 1. Screw drive mechanisms are prone to wear and tear over long-term use, leading to asynchronous movement on both sides and deformation of the hatch. Furthermore, the low efficiency of screw transmission affects the takeoff and landing efficiency of the UAV. Linkage drive mechanisms require high installation precision, and hinge points are prone to loosening, easily causing abnormal hatch movement trajectories. Gear and rack transmission mechanisms are susceptible to wear or corrosion in dusty or humid environments. These mechanisms require high levels of maintenance and require frequent upkeep.
[0005] 2. For vehicle-mounted machine nests, linkage opening and closing mechanisms, screw drive and self-locking mechanisms, and gear rack translation mechanisms have poor vibration resistance, which can easily lead to deformation, loosening, and rapid failure.
[0006] 3. The motors for the linkage opening and closing mechanism, the screw drive and self-locking mechanism, and the gear rack translation mechanism all need to be arranged close to the door opening and closing actuator, resulting in low space utilization, large space occupation in the cabin, and affecting the overall size of the machine nest.
[0007] 4. Currently, after a power outage, the drone's cabin cannot be easily switched to manual control, and the hatch is not opened or closed in a timely manner, which may cause damage to the drone or the equipment inside the cabin. Summary of the Invention

The external clutch control knob is used to control the power transmission between the capstan and the motor, and manual opening and closing of the cabin door is realized.

The specific structure design and implementation method are as follows.
[0056] The unmanned aerial vehicle nest cabin door opening and closing mechanism includes a plurality of twisted flexible steel wire ropes. In the specific implementation, the embodiment of the application adopts a mode of arranging four steel wire ropes to ensure that the left and right box covers can operate stably. Specifically, it includes a first steel wire rope 501, a second steel wire rope 502, a third steel wire rope 503, and a fourth steel wire rope 504. The first steel wire rope 501, the second steel wire rope 502, the third steel wire rope 503, and the fourth steel wire rope 504 pass through the wire routing pipe and are constrained by the corresponding guide wheels at the four corners of the cabin body frame 1 near the box opening, so that the steel wire rope runs parallel to the direction of the box cover movement. The four guide wheels include a first guide wheel 301, a second guide wheel 302, a third guide wheel 303, and a fourth guide wheel (not shown in the figure), wherein the first guide wheel 301 and the second guide wheel 302 are arranged on one side perpendicular to the running direction of the steel wire rope, and the third guide wheel 303 and the fourth guide wheel are arranged on the other side perpendicular to the running direction of the steel wire rope.

[0057] The first box cover 201 (left) and the second box cover 202 (right) are connected to the steel wire rope through the box cover connecting arm 6. Specifically, the first box cover 201 is connected to the first steel wire rope 501 and the third steel wire rope 503 through two connecting arms 6, respectively, at positions between the two guide wheels, and is driven by the first steel wire rope 501 and the third steel wire rope 503 to open and close. The second box cover 202 is connected to the second steel wire rope 502 and the fourth steel wire rope 504 through two connecting arms 6, respectively, at positions between the two guide wheels. The second box cover 202 is driven by the second steel wire rope 502 and the fourth steel wire rope 504 to open and close.
[0058] Each group of steel wire rope is fixed at the winch mechanism capstan, and the forward and reverse rotation of the capstan realizes the reciprocating motion of the steel wire rope, which drives the opening and closing of the hatch. The first steel wire rope 501 and the third steel wire rope 503 are guided through independent wire pipes 7, and the two ends of each are connected to the four wheel grooves of the first capstan 4011 one by one, and the opening and closing control of the first hatch cover 201 can be realized by controlling the forward and reverse rotation of the first capstan 4011. The second steel wire rope 502 and the fourth steel wire rope 504 are guided through independent wire pipes 7, and the two ends of each are connected to the four wheel grooves of the second capstan 4021 one by one, and the opening and closing control of the second hatch cover 202 can be realized by controlling the forward and reverse rotation of the second capstan 4021.
[0059] The clutch controller 9 controls the clutch of the winch mechanism, so that the power transmission between the driving motor and the capstan is disconnected or closed, and the switching between manual and electric opening and closing of the hatch is realized. The left and right hatch covers are installed on the cabin frame 1 using slide rails 12.
[0060] The first winch 401 and the second winch 402 are completely identical in structure, and the winch mechanism drives the steel wire rope connected to the capstan to perform reciprocating motion. The reduction motor 801 is connected to the clutch component through a shaft coupling 805, and the clutch driving gear is engaged with the capstan for transmission. The capstan has four steel wire rope fixing channels for driving two sets of steel wire rope transmission. The head and tail of each group of steel wire ropes (the first steel wire rope 501 and the third steel wire rope 503 form a group, and the second steel wire rope 502 and the fourth steel wire rope 504 form a group) are wound in opposite directions on the capstan, that is, one set of winch controls the opening and closing of one side door.

[0062] In actual use, the Bowden wire steel wire rope 806 drives the clutch yoke 803 to rotate to the left, so that the clutch driving gear 804 is separated from the capstan, and the hatch door can be manually pushed and pulled to perform the opening and closing action. After the force of the steel wire rope is released, the reset spring pushes the clutch driving gear 804 to engage with the capstan, and the electric opening and closing of the hatch door can be switched. All modules are installed on the mounting base 802, and the mechanism is arranged in the cabin through the mounting base 802 mounting hole.
[0063] Manual switch door operation instruction: insert the general 6mm hexagonal wrench 10 into the clutch controller 9, rotate clockwise by 90°, the clutch controller 9 borden wire rope 806 drives the clutch fork 803 to move left, and drives the clutch driving gear 804 to disengage from the winch. There is a 90° limiting control mechanism 901 behind the clutch controller 9 to avoid automatic reset of the clutch.
[0064] In summary, the unmanned aerial vehicle nest cabin door opening and closing mechanism provided in the application has good anti-vibration performance, uses a steel wire rope to drive the cabin door to move, and the flexible transmission can effectively avoid the influence of vibration on the transmission mechanism, such as displacement, deformation, and the like, which leads to mechanism jamming failure.
