Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a multi-rotor UAV base station. Background Technology

[0002] Multi-rotor drones maintain a stable hovering or flying state in the air through their power system, and carry communication base station equipment such as self-organizing network radios, cluster micro base stations, and LTE micro base stations on their fuselage. The communication base station is usually installed at the lower end of the multi-rotor drone, which makes it easier for the base station antenna to transmit signals downward or in all directions, reduces the obstruction of signals by the fuselage, and improves communication efficiency. This provides technical inspiration for drone base stations.

[0003] Research on drone base stations revealed the following problems:

[0004] After the drone base station is installed at the bottom of the drone, when the drone lands, due to the complex outdoor terrain, when the ground is uneven, the terrain is likely to bulge up to the top of the drone's landing gear, so the ground is likely to impact the bottom of the drone base station, causing the drone base station to be unable to provide cushioning protection for the bottom when the drone lands.

[0005] Currently, the existing technology CN202420024076.7 discloses a drone base station. This utility model has a rotating upper and lower pole body that can be folded; a mounting frame installed on the upper pole body; an environmental monitoring module installed on the mounting frame for monitoring the environment; a signal transceiver module installed on the mounting frame for signal transmission with the drone; and an electrical control cabinet installed on the upper or lower pole body and located below the mounting frame, which is electrically connected to the environmental monitoring module and the signal transceiver module via wires. This allows for monitoring of the surrounding environment to improve the adaptability of the drone, while also enabling information interaction with the drone, thus facilitating its use.

[0006] This invention primarily addresses the problem that drone base stations cannot provide buffer protection for the lower part of the drone during landing. Utility Model Content

[0007] The present invention aims to solve the problems mentioned in the background, thereby providing a multi-rotor drone base station.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A multi-rotor drone base station includes a drone, with rotors mounted around the outside of the drone and a communication base station located in the middle of the lower end of the drone.

[0010] The lower end of the communication base station is provided with a sleeve, and a telescopic cylinder is slidably nested and stacked at the lower end of the sleeve;

[0011] The drone is equipped with a battery and an electric motor, which drives the rotor to rotate.

[0012] The communication base station is equipped with an antenna inside. The communication base station transmits and receives signals through the antenna. The UAV communicates with the ground communication terminal through the communication base station. The ground communication terminal is the UAV controller.

[0013] In one possible implementation, the telescopic cylinder is T-shaped on its side, and an inner cavity is opened inside the lower end of the sleeve. The upper end of the telescopic cylinder slides and nests vertically inside the inner cavity, and a hole is passed through the lower end of the telescopic cylinder.

[0014] In one possible implementation, a pivot is hinged inside the hole of the telescopic cylinder, and a crossbar is swung to both sides of the pivot. A protective plate is swung to the side of the crossbar away from the pivot. An inclined plate is provided at the upper end of the protective plate, and a sliding column passes through the upper end of the inclined plate. Tracks are provided on both sides of the lower end of the communication base station near the sliding column.

[0015] In one possible implementation, the rotating shaft swings vertically, and the crossbar and protective plate are matched and arranged at the lower end of the communication base station.

[0016] In one possible implementation, the protective plate is arc-shaped with an arc angle of 150-170°, and the protective plate swings vertically to one side of the pivot via a crossbar.

[0017] In one possible implementation, the inclined plates are arranged at an upward inclination of 25-60°, starting from the protective plate. When the protective plate is not swinging upward, the inclined plates are located on one side of the lower end of the track.

[0018] In one possible implementation, the inclined plates are arranged at an upward inclination of 25-60°, starting from the protective plate. Therefore, when the protective plate swings upward, the inclined plates can drive the sliding column to slide upward at the lower end of the protective plate.

[0019] In one possible implementation, grooves are provided on both sides of the lower end of the track, the track is inclined at 45° in the vertical direction, and the track is matched with the sliding column.

[0020] In one possible implementation, the upper end of the sliding post slides inside the groove of the track, and both ends of the sliding post are nested inside the groove of the track.

[0021] The beneficial effects of this utility model are:

[0022] 1. When the lower side of the drone is impacted by the ground, it first impacts the lower part of the protective plate of the communication base station. The protective plate swings on one side of the pivot via a crossbar. Through the lever principle, the protective plate on the other side of the pivot swings downward. The upper inclined plate of the protective plate on one side of the pivot drives the sliding column to slide upward, while the upper inclined plate of the protective plate on the other side of the pivot drives the sliding column to slide downward. The sliding column slides inside the track. Since the track is set in a vertically inclined direction, the upward sliding column can generate downward sliding inertia. Therefore, the inclined plate and the sliding column can assist the protective plate to slide back to its downward position. By swinging the protective plate in a vertically inclined direction, the impact of the ground on the communication base station during landing can be reduced, avoiding the situation where the ground collides with the lower part of the communication base station due to uneven ground terrain, which could easily damage the communication base station.

[0023] 2. When the lower protective plate of the communication base station is impacted by the ground, the protective plate as a whole generates an upward impact force. The protective plate drives the telescopic cylinder to slide upward through the rotating shaft. Through the telescopic cylinder and the sleeve extending and retracting in a vertical direction, it can buffer the lower end of the communication base station. Attached Figure Description

[0036] Please see Figure 1-5 In the embodiments of this utility model,

[0037] Example 1: A multi-rotor drone base station includes a drone 1, with rotors 101 mounted around the outside of the drone 1, and a communication base station 102 located in the middle of the lower end of the drone 1.

[0038] The lower end of the communication base station 102 is provided with a sleeve 2, and a telescopic cylinder 201 is slidably nested and stacked at the lower end of the sleeve 2;

[0039] The UAV 1 is equipped with a battery and an electric motor, which drives the rotor 101 to rotate.

[0040] The communication base station 102 is equipped with an antenna. The communication base station 102 transmits and receives signals through the antenna. The UAV 1 communicates with the ground communication terminal through the communication base station 102. The ground communication terminal is the UAV controller.

[0041] The telescopic cylinder 201 has a "T"-shaped side profile. An inner cavity is formed inside the lower end of the sleeve 2. The upper end of the telescopic cylinder 201 slides vertically within this inner cavity. A through hole is formed inside the lower end of the telescopic cylinder 201. (Refer to the attached instruction manual for details.) Figure 5 As shown;

[0042] Example 2: Refer to the attached instruction manual Figure 2-5The difference between Embodiment 2 and Embodiment 1 is that a rotating shaft 3 is hinged inside the hole of the telescopic cylinder 201, and a crossbar 301 is swung and connected to both sides of the rotating shaft 3. A protective plate 302 is swung and connected to the side of the crossbar 301 away from the rotating shaft 3. An inclined plate 401 is provided at the upper end of the protective plate 302, and a sliding column 402 passes through the upper end of the inclined plate 401. Tracks 4 are provided on both sides of the lower end of the communication base station 102 near the sliding column 402.

[0043] Among them: the rotating shaft 3 swings vertically, the crossbar 301 and the protective plate 302 are matched, and the crossbar 301 and the protective plate 302 are arranged at the lower end of the communication base station 102;

[0044] The protective plate 302 is arc-shaped with an arc angle of 150-170°. The protective plate 302 swings vertically on one side of the rotating shaft 3 via the crossbar 301.

[0045] Starting from the protective plate 302, the inclined plate 401 is arranged at an upward inclination of 25-60°. When the protective plate 302 is not swinging upward, the inclined plate 401 is located on one side of the lower end of the track 4. Please refer to the instruction manual appendix. Figure 4 As shown;

[0046] The inclined plate 401 is arranged at an upward inclination of 25-60° with the protective plate 302 as the starting point. Therefore, when the protective plate 302 swings upward, the inclined plate 401 can drive the sliding column 402 to slide upward at the lower end of the protective plate 302.

[0047] Grooves are provided on both sides of the lower end of the track 4. The track 4 is inclined at 45° in the vertical direction. The track 4 is matched with the sliding column 402.

[0048] The upper end of the sliding column 402 slides inside the groove of the track 4, and both ends of the sliding column 402 are nested inside the groove of the track 4 to prevent the sliding column 402 from falling out of the track 4 due to the weight of the protective plate 302.

[0049] Working principle:

[0050] The UAV 1 is equipped with a battery and an electric motor. The electric motor drives the rotor 101 to rotate. The communication base station 102 is equipped with an antenna. The communication base station 102 transmits and receives signals through the antenna. The UAV 1 communicates with the ground communication terminal through the communication base station 102, so that the ground terminal can control the UAV 1 to take off through the rotor 101 through the communication base station 102. After takeoff, the UAV 1 lands on the ground. The communication base station 102 is located at the lower end of the UAV 1. When one side of the lower end of the UAV 1 is impacted by the ground, it first impacts the lower part of the protective plate 302 on the lower side of the communication base station 102. The protective plate 302 swings on one side of the pivot 3 through the crossbar 301. Through the lever principle, the protective plate 302 on the other side of the pivot 3 swings downward.

[0051] The inclined plate 401 at the upper end of the protective plate 302 on one side of the rotating shaft 3 drives the sliding column 402 to slide upward, while the inclined plate 401 at the upper end of the protective plate 302 on the other side of the rotating shaft 3 drives the sliding column 402 to slide downward. The sliding column 402 slides inside the track 4. Since the track 4 is set in a vertically inclined direction, the sliding column 402 that slides upward can generate downward sliding inertia. Therefore, the inclined plate 401 and the sliding column 402 can assist the protective plate 302 to slide downward back to its original position. When the lower protective plate 302 of the communication base station 102 is impacted by the vertically inclined swing of the protective plate 302, the protective plate 302 as a whole generates an upward impact force. The protective plate 302 drives the telescopic cylinder 201 to slide upward through the rotating shaft 3.
