Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft control devices, and in particular relates to a control device for aircraft landing. Background Technology

[0002] Aircraft are widely used in civilian aerial photography, agricultural plant protection, power line inspection and other fields. With the development of technology, the application scenarios of these aircraft are constantly expanding and the demand is continuously rising. During their flight, the precise control of the landing phase is particularly critical, and the landing control device is the core equipment to achieve this goal. At present, the landing control devices of the aforementioned aircraft suitable for low-altitude operations are mostly remote control type. The operator sends landing-related command signals to the aircraft through the operating components on the remote control, thereby adjusting the landing attitude and speed of the aircraft in real time.

[0003] However, some existing control devices are often difficult to disassemble quickly. When a control device malfunctions and requires repair, the complex disassembly process consumes a significant amount of time. This not only affects the operational efficiency of the aircraft, but in emergency mission scenarios, the inability to repair equipment in a timely manner may also lead to landing errors and unnecessary losses.

The mounting plate 111 is connected to the lower housing 11 by bolts, and the top of the mounting plate 111 is used to install the control elements of the control device.

[0040] The quick-release mechanism 2 also includes a connecting component 22, which is disposed on the top of the upper housing 1 and is used to connect the upper housing 1 and the lower housing 11; and

[0041] Drive component 23 is disposed inside the connecting component 22 and is used to provide power for connecting the upper housing 1 and the lower housing 11 of the connecting component 22.

[0042] The transmission assembly 24 is located at the bottom of the drive assembly 23.

The power provided by the transmission assembly 24 is transmitted to the connection assembly 22.

[0043] The connecting assembly 22 includes a connecting sleeve 221 that is slidably connected to the inner wall of the mounting groove 21. The bottom end of the connecting sleeve 221 extends into the interior of the mounting sleeve 211 and is slidably connected to the mounting sleeve 211.

[0044] The drive assembly 23 includes a threaded block 231 disposed inside the connecting sleeve 221. The inner wall of the connecting sleeve 221 has a threaded groove. The threaded block 231 is threadedly connected to the connecting sleeve 221 through the threaded groove on the inner wall of the connecting sleeve 221. A connecting rod 232 is fixedly connected to the top of the threaded block 231.

The side of each limiting slider away from the pressing block 241 extends into the corresponding limiting groove and is slidably connected to the corresponding limiting groove. The inner bottom wall of the connecting sleeve 221 is provided with a central groove. The bottom of the pressing block 241 is fixedly connected with a limiting rod. The bottom end of the limiting rod extends into the central groove and is slidably connected to the central groove. When the positioning bead 222 is not working, the position of the positioning bead 222 is limited by the limiting rod, so that the positioning bead 222 will not affect the next operation.

[0046] The heat dissipation mechanism 3 also includes several heat-conducting pillars 33 fixedly connected to the bottom of the mounting plate 111. Each heat-conducting pillar 33 has a heat-conducting copper core 331 passing through it. The heat-conducting copper core 331 is fixedly connected to the corresponding heat-conducting pillar 33. The heat-conducting pillars 33 are evenly distributed on the bottom of the mounting plate 111.

[0047] Several heat dissipation fins 332 are fixedly connected to the outer walls of several heat conduction pillars 33. Ventilation slots 333 are provided on the mounting plate 111. Several heat dissipation fins 332 are fixedly connected to the corresponding heat conduction pillars 33 by welding.

[0048] A specific application of this embodiment is as follows: When installing the upper housing 1 and the lower housing 11, the upper housing 1 and the lower housing 11 are initially aligned. At this time, the retaining plate is inserted into the retaining groove, which can quickly align the installation positions of the two. Then, the connecting sleeve 221 is inserted through the mounting groove 21 through the upper housing 1, and the bottom end of the connecting sleeve 221 is inserted into the mounting sleeve 211. Then, the knob 233 is rotated. The knob 233 drives the threaded block 231 to rotate through the connecting rod 232. Since the threaded block 231 is threadedly connected to the threaded groove on the inner wall of the connecting sleeve 221, the threaded block 231 will move downward along the inner wall of the connecting sleeve 221. The downward-moving threaded block 231 compresses the spring 242. The spring 242 transmits the pressure to the compression block 241. Due to its trapezoidal structure with a larger top and a smaller bottom, the compression block 241 pushes the positioning bead 222 outward when it moves downward. After being compressed, part of the volume of the positioning bead 222 is embedded in the mounting sleeve 211. In the hemispherical positioning groove 223 on the inner wall of 11, the spherical positioning bead 222 cooperates with the hemispherical positioning groove 223 to lock the connecting sleeve 221 and the mounting sleeve 211, completing the installation of the upper and lower shells. When disassembling, the knob 233 is rotated in the opposite direction, the threaded block 231 moves upward, the spring 242 elastically resets, the pressing block 241 moves upward accordingly, the positioning bead 222 loses the pushing force of the pressing block 241, and with the assistance of its own sliding characteristics and the limiting rod and other structures, it retracts into the connecting sleeve 221, releasing the lock with the positioning groove 223, and then the upper shell 1 can be removed upward, achieving a quick disassembly operation. The limiting slider on the outer wall of the pressing block 241 slides in the limiting groove on the inner wall of the connecting sleeve 221, and the limiting rod at the bottom slides in the central groove, ensuring the stable movement of the pressing block 241, and also limiting the position of the positioning bead 222 after reset, ensuring normal operation during the next installation.

[0049] When the aircraft landing control device is working, the heat generated by the control elements is transferred to the mounting plate 111 because the control elements are mounted on the mounting plate 111. The mounting plate 111 transfers the heat to the heat-conducting pillars 33, and the heat-conducting copper core 331 accelerates the transfer efficiency, quickly dissipating the heat. The heat dissipation area is then increased by the heat dissipation fins 332 on the outer wall of the heat-conducting pillars 33. External airflow enters from the air inlet 31 at the rear of the lower shell 11. The filter at the air inlet can filter impurities. When the airflow passes through the area of ​​the heat-conducting pillars 33 and the heat dissipation fins 332, it exchanges heat with them and absorbs heat. The trapezoidal ventilation holes on the mounting plate 111... The air duct 333 provides a channel for airflow and can converge and guide the airflow. The narrower duct at the bottom can increase the airflow speed and reduce the stagnation at the bottom of the mounting plate 111, while the wider duct at the top can allow more hot airflow to enter the upper housing 1 smoothly, avoiding airflow congestion caused by narrow channels. The hot airflow entering the upper housing 1 exchanges heat with the control element again, taking away the heat on the control element, and finally exits from the air outlet 32 ​​of the upper housing 1, forming a continuous air convection circulation of "bottom in and top out", which efficiently removes the heat in the control device and ensures that the control element operates stably in a suitable temperature environment.
