Description

Technical Field

[0001] This utility model belongs to the field of drone battery charging technology, and in particular relates to an embedded electric tilt-rotor drone laser power supply device. Background Technology

[0002] For most tiltrotor drones, the power consumption rate during vertical takeoff is approximately three times that during level flight (assuming all motors are tilted). If speed is required during takeoff, the power consumption rate is even faster. This often results in a significant amount of power being consumed by the time the drone switches to level flight, impacting flight time and preventing the drone from reaching its full speed during takeoff. Furthermore, during the transition from vertical to level flight in an electric tiltrotor drone, there is a "gap" due to insufficient vertical thrust and forward speed caused by motor tilting. This not only leads to a decrease in flight altitude but can also increase the risk of a crash. Therefore, providing sufficient power to the drone during both the vertical takeoff and the transition phases—specifically, the laser charging device for electric tiltrotor drones—is of great practical significance for the drone's flight performance and long-endurance safe flight.

[0003] The laser charging device on a drone includes a laser charging plate and a battery. The laser charging plate receives a laser beam from the ground, performs photoelectric conversion, and finally stores the converted electrical energy in the drone's battery. The effectiveness of the laser charging plate in receiving laser light depends on the angle of the laser beam's entry: the larger the angle, the higher the photoelectric conversion efficiency; the efficiency is highest when the laser beam enters the charging plate perpendicularly. Therefore, to achieve laser charging of a drone's battery at a specific altitude, the laser emitter on the ground must first be moved back and forth, and then the emission angle adjusted to maximize the photoelectric conversion efficiency. However, for a drone at a distant altitude, the laser beam is angled (not perpendicular) towards the charging plate, affecting the photoelectric conversion efficiency, and thus the charging efficiency of the drone's battery. Utility Model Content

[0004] In view of this, the present invention aims to propose an embedded electric tilt-rotor drone laser power supply device to improve the charging efficiency of drone batteries.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An embedded electric tiltrotor drone laser power supply device includes a groove on the bottom surface of the drone, in which a laser charging plate is embedded. The laser charging plate is connected to a battery on the drone. One end of the laser charging plate is the front end, the other end is the rear end, and the lower surface is the laser receiving end. The front end of the laser charging plate is rotatably mounted in the groove via a rotating shaft. The rotating shaft is horizontal and perpendicular to the central axis of the tiltrotor drone. The rear end of the laser charging plate is mounted to the drone via a linkage structure. This linkage structure is driven by a motor, causing the laser charging plate to rotate downward around the rotating shaft.

[0007] Furthermore, the linkage structure includes a hinged first rod and a second rod, the distal end of the first rod being rotatably mounted in a groove via a hinge shaft, and the distal end of the second rod being hinged to the top surface of the laser charging plate 2.

[0008] The hinge and the rotation axis are parallel;

[0009] The motor drives the hinge shaft to rotate, thereby driving the linkage structure to move.

[0010] Furthermore, the groove is formed on the bottom surface of the UAV wing, the motor is set on the top surface of the wing, and the motor is connected to the wing through a gear transmission structure and a linkage structure. The bottom of the groove has a through hole corresponding to the gear transmission structure.

[0011] Furthermore, at least two grooves are symmetrically arranged on the two wings of the UAV.

[0012] Furthermore, the bottom surface of the laser charging plate is flush with the bottom surface of the wing.

[0013] Furthermore, the motor is positioned close to the fuselage of the drone.

[0014] Compared with existing technologies, the embedded electric tilt-rotor UAV laser power supply device of this utility model has the following advantages:

[0015] (1) In this utility model, the laser charging plate is rotatably mounted on the drone, and the motor adjusts its rotation angle through the linkage structure so that the laser charging plate at any position can be adjusted to face the laser beam from the ground, thereby improving the laser receiving effect of the laser charging plate, thereby improving the photoelectric conversion efficiency and improving the charging effect of the drone battery.

[0016] (2) In this utility model, the laser charging plate is embedded in the bottom surface of the drone wing, the bottom surface of the laser charging plate is flush with the bottom surface of the drone, and the bottom of the groove is opened with through holes to realize the installation and meshing of the gear transmission structure, so as to minimize the flight resistance of the wing and reduce the battery power consumption.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embedded electric tiltrotor drone laser power supply device includes two symmetrically formed grooves 4 on the underside of the two wings 1 of the drone, each containing a laser charging plate 2. The laser charging plate 2 is connected to the drone's battery. The laser charging plate 2 receives the laser beam, performs photoelectric conversion, and stores the converted electrical energy in the drone's battery, thus charging the battery. The laser charging plate 2 can adopt the structure currently used for laser beam charging in drones; it is a conventional structure and will not be described in detail here.

[0027] The laser charging plate 2 has one end as the front end and the other end as the rear end, with its lower surface serving as the laser receiver. The front end of the laser charging plate 2 is rotatably mounted in a groove 4 via a horizontal shaft 3 perpendicular to the central axis of the tilt-rotor drone. The rear end of the laser charging plate 2 is mounted at the bottom of the groove 4 via a connecting rod structure 5. A motor 6 is mounted on the top surface of the wing 1, positioned close to the drone fuselage, and connected to the drone's battery. The motor 6 drives the connecting rod structure 5 via a gear transmission structure 7, causing the laser charging plate 2 to rotate downwards around the shaft 3.

[0028] Specifically, the linkage structure 5 includes a hinged first rod 51 and a second rod 52. After the first rod 51 and the second rod 52 are hinged, the distal end of the first rod 51 (the end away from its hinge with the second rod) is rotatably mounted in the groove 4 via a hinge shaft 9 parallel to the rotating shaft 3. The distal end of the second rod 52 (the end away from its hinge with the first rod) is hinged to the top surface of the laser charging plate 2. The gear transmission structure 7 includes a meshing driving wheel and a driven wheel. The driving wheel is mounted on the main shaft of the motor 6, and the driven wheel is mounted on the hinge shaft 9. A through hole is opened at the bottom of the groove 4 corresponding to the gear transmission structure 7 to avoid the gear transmission structure 7, so as to ensure the installation of the gear transmission structure 7 and the meshing of the driving wheel and the driven wheel, so that the motor power is transmitted to the hinge shaft through the gear transmission structure 7, driving the hinge shaft 9 to rotate. The motor 6 drives the hinge shaft 9 to rotate through the gear transmission structure 7. Since the hinge shaft 9 and the first rod 51 are fixed, the rotation of the hinge shaft 9 drives the first rod 51 to rotate, causing the linkage structure 5 to open, and finally causing the laser charging plate 2 to rotate downward around the rotating shaft 3.

[0029] Preferably, the bottom surface of the laser charging plate 2 is flush with the bottom surface of the wing 1.

[0030] The operation process of this utility model is as follows: When charging a drone at a certain altitude, first, the drone's nose is pointed towards the laser emitter on the ground. Then, motor 6 is turned on to open the linkage structure 5. The linkage structure 5 drives the laser charging plate 2 to rotate downwards around the pivot 3 until the laser charging plate 2 is aligned with the laser beam emitted by the laser emitter. The laser charging plate 2 receives the laser beam and performs photoelectric conversion, storing electrical energy in the drone's battery, thus charging the battery. After charging is completed, the motor is turned on again, driving the linkage structure 5 to rotate the laser charging plate 2 upwards around the pivot 3 until it returns to its initial state (embedded in the groove 4).

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
