Description

Technical Field

[0001] This invention relates to the field of drone takeoff technology, and in particular to an electric control limit and unlocking device for a vehicle-mounted skid drone. Background Technology

[0002] In recent years, with the rapid development of the low-altitude economy, fixed-wing drones have been widely used in many fields such as border reconnaissance, meteorological monitoring, logistics transportation, and emergency rescue. Various missions have also placed higher demands on the rapid deployment and response of drones. The traditional take-off method requires a predetermined runway for drones to take off, which severely limits the rapid deployment of drones in complex terrain environments or in the absence of dedicated runways.

[0003] Vehicle-mounted takeoff is a common method for drones. It typically involves fixing the drone in a dedicated takeoff rack on a vehicle platform. After the vehicle accelerates to a certain speed, it uses aerodynamics to generate sufficient lift before unlocking and releasing the drone for rapid takeoff. Its high mobility and flexibility make it suitable for rapid response missions in different environments.

[0004] To achieve locking and unlocking of vehicle-mounted skid-mounted drones, most existing publicly available vehicle-mounted drone takeoff devices use soft ropes to secure the drone, for example:

[0005] The publication CN113815886B, titled "Take-off System for Slender-winged Unmanned Aerial Vehicles," proposes a take-off system for unmanned aerial vehicles with slender wings. The system connects the take-off frame to the unmanned aerial vehicle fuselage via a fixing rope. By adjusting the adjusting bolt, the tension of the fixing rope is kept within a suitable range, thus securing the unmanned aerial vehicle to the take-off frame. The fixing rope is then cut using an electronic wire cutter. Although the tightness of this system is adjustable, its stability is somewhat insufficient due to factors such as the elasticity of the fixing rope.

[0006] The patent application CN111688946B, titled "Unmanned Aerial Vehicle Vehicle-Mounted Launch Method and Apparatus," proposes a method and apparatus for launching unmanned aerial vehicles (UAVs) from a vehicle. The traction adapter module and the stabilization structure module are detachably connected and fixed together by a fixing rope. When the UAV reaches takeoff speed, the nylon rope is cut to release the UAV. This solution improves the adaptability of the UAV through modularity. However, the cumbersome use of the nylon rope for fixing makes it less convenient to use when launching the UAV multiple times.

[0007] In summary, the aforementioned patents for the design of vehicle-mounted drone takeoff devices primarily rely on a fixed rope to connect and secure the drone. While the structure is relatively simple, its ease of use needs improvement for multiple drone takeoff missions. Furthermore, the stability of securing the drone during vehicle-mounted platform movement also needs to be enhanced. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to address the deficiencies mentioned in the background art by providing an electric control limit and unlocking device for a vehicle-mounted skid drone.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] An electric control limit and unlocking device for a vehicle-mounted skid-mounted unmanned aerial vehicle includes a mounting plate, a locking tongue, a limit bar, a first rotating shaft, a second rotating shaft, a return spring, a stop block, and a linear motor.

[0011] The mounting plate is fixed on the vehicle-mounted takeoff frame and is used to install the locking tongue, limit strip, first rotating shaft, second rotating shaft, stop block and linear motor;

[0012] One end of the first rotating shaft is perpendicularly fixed to the mounting plate; the locking tongue is mounted on the mounting plate through the first rotating shaft and can rotate freely around the first rotating shaft; the locking tongue includes a pressure-receiving part and a locking part, the locking part is provided with a locking groove that cooperates with the front end of the skid of the skid drone, and the pressure-receiving part is located at the lifting platform of the vehicle-mounted takeoff frame;

[0013] The locking part of the latch has a limiting groove on the back of the locking groove for cooperating with the limiting strip;

[0014] One end of the second rotating shaft is perpendicularly fixed to the mounting plate; the limiting strip is mounted on the mounting plate via the second rotating shaft in its middle part and can rotate freely around the second rotating shaft;

[0015] The linear motor and the stop block are respectively arranged on both sides of the limiting strip and are fixed on the mounting plate, wherein the stop block is located below the locking tongue;

[0016] One end of the return spring is fixedly connected to the stop block, and the other end is fixedly connected to the lower end of the limiting strip, and is in a compressed state; when the skid drone does not land on the vehicle-mounted take-off frame, the lower end of the limiting strip is held in place by the return spring, the upper end is against the locking tongue, and the upper end of the limiting strip is located outside the limiting groove.

[0017] When the skid drone lands on the vehicle-mounted takeoff frame, the pressure part of the locking tongue is pressed by the skid of the skid drone, causing the locking tongue to rotate around the first rotating shaft. This causes the locking groove on the locking part to engage with the front end of the skid of the skid drone. At this time, the return spring pushes the limiting strip to rotate around the second rotating shaft, causing the upper end of the limiting strip to rotate into the limiting groove of the locking tongue and abut against the locking tongue to limit the rotation of the locking tongue.

[0018] The output shaft of the linear motor is coaxial with the reset spring, and is used to overcome the elastic force of the reset spring to push the limit bar to rotate around the second rotating shaft when unlocking is required, so that the upper end of the limit bar disengages from the limiting groove of the lock tongue, thereby causing the skid drone to drive the lock tongue to rotate and unlock.

[0019] As a further optimization of the electric control limit and unlocking device for vehicle-mounted skid drones of the present invention, the mounting plate, locking tongue, limit bar, first rotating shaft, and second rotating shaft are all made of aluminum alloy.

[0020] As a further optimization of the electric control limit and unlocking device for vehicle-mounted skid drones of the present invention, the output end of the linear motor is provided with a buffer pad.

[0021] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:

[0022] 1. Compared to structures that use fixed ropes to secure drones, all key components of this invention are reusable mechanical and electric structures, reducing maintenance costs and improving operational efficiency, making it particularly suitable for drone missions requiring multiple takeoffs.

[0023] 2. The vehicle-mounted skid-mounted UAV electric control limit and unlocking device designed in this invention has a simple and reliable structure. It achieves automatic limit and locking through structural design without the need for cumbersome disassembly. It is particularly suitable for vehicle-mounted platform launch in field missions or rapid response mission scenarios. Attached Figure Description

[0034] like Figure 1 As shown, the present invention discloses an electric control limit and unlocking device for a vehicle-mounted skid drone, including a mounting plate, a locking tongue, a limit bar, a first rotating shaft, a second rotating shaft, a return spring, a stop block, and a linear motor;

[0035] The mounting plate is fixed on the vehicle-mounted takeoff frame and is used to install the locking tongue, limit strip, first rotating shaft, second rotating shaft, stop block and linear motor;

[0036] One end of the first rotating shaft is perpendicularly fixed to the mounting plate; the locking tongue is mounted on the mounting plate through the first rotating shaft and can rotate freely around the first rotating shaft; the locking tongue includes a pressure-receiving part and a locking part, the locking part is provided with a locking groove that cooperates with the front end of the skid of the skid drone, and the pressure-receiving part is located at the lifting platform of the vehicle-mounted takeoff frame;

[0037] The locking part of the latch has a limiting groove on the back of the locking groove for cooperating with the limiting strip;

[0038] One end of the second rotating shaft is perpendicularly fixed to the mounting plate; the limiting strip is mounted on the mounting plate via the second rotating shaft in its middle part and can rotate freely around the second rotating shaft;

[0039] The linear motor and the stop block are respectively arranged on both sides of the limiting strip and are fixed on the mounting plate, wherein the stop block is located below the locking tongue;

[0040] One end of the return spring is fixedly connected to the stop block, and the other end is fixedly connected to the lower end of the limiting strip, and is in a compressed state; when the skid drone does not land on the vehicle-mounted takeoff frame, the lower end of the limiting strip is held in place by the return spring, the upper end abuts against the locking tongue, and the upper end of the limiting strip is located outside the limiting groove, such as Figure 2 As shown;

[0041] When the skid-mounted drone lands on the vehicle-mounted takeoff rack, the pressure part of the locking tongue is pressed by the skid of the drone, causing the locking tongue to rotate around the first pivot. This causes the locking groove on the locking part to engage with the front end of the skid of the drone. At this time, the return spring pushes the limiting bar to rotate around the second pivot, causing the upper end of the limiting bar to rotate into the limiting groove of the locking tongue and abut against the locking tongue, thereby restricting the rotation of the locking tongue. Figure 3 As shown;

[0042] The output shaft of the linear motor is coaxial with the return spring, and is used to overcome the elastic force of the return spring to push the limit bar to rotate around the second pivot when unlocking is required. This causes the upper end of the limit bar to disengage from the limiting groove of the lock tongue, thereby causing the skid drone to rotate the lock tongue to unlock. Figure 4 As shown.

[0043] The mounting plate, locking tongue, limit bar, first pivot, and second pivot are all preferably made of aluminum alloy.

[0044] The output end of the linear motor is equipped with a buffer pad.
