A horizontally adjustable base for landing a surveying drone

Abstract

This utility model relates to the field of unmanned aerial vehicle (UAV) technology and discloses a horizontally adjustable base for landing a surveying UAV. The horizontally adjustable base includes a frame, a tail fin fixedly mounted on the frame, one end of a mounting rod fixedly mounted on the frame, and a support assembly on the frame. The support assembly includes a frame, and the frame is fixedly mounted at the bottom of the frame. To prevent damage to the surveying module caused by the UAV tilting, this horizontally adjustable base incorporates a support assembly. When the UAV lands on uneven ground, this assembly, in conjunction with a hinged frame, can rotate between a vertical limiting frame and a tilt limiting frame, causing the cylinder and support rod to adaptively adjust to the ground slope, ensuring the rubber pad remains in contact with the ground.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a horizontally adjustable base for landing a surveying UAV. Background Technology

[0002] Surveying drones are widely used in fields such as geological exploration, topographic mapping, and engineering monitoring. The high-precision surveying equipment they carry requires extremely high stability from the drone itself.

[0003] A typical horizontally adjustable landing frame for surveying drones consists of multiple sets of retractable support legs, attitude sensors, a drive adjustment system, shock absorption components, and a central control unit. The support legs are made of high-strength aluminum alloy, and each set is equipped with a servo motor and ball screw, enabling independent retraction adjustment from 0 to 150 mm. The attitude sensors integrate a three-axis gyroscope and accelerometer to monitor the fuselage tilt angle in real time with an accuracy of ±0.1°. The drive adjustment system receives sensor signals, calculates the retraction amount of each support leg through the central control unit, and drives the servo motor to complete the adjustment action. The shock absorption components install silicone pads and springs at the bottom of the support legs to absorb landing impacts. The central control unit uses an embedded chip with a built-in horizontal adjustment algorithm, achieving a response time of less than 0.5 seconds.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional base frames are mostly rigid fixed structures with non-adjustable support leg angles. When landing on uneven ground, the fuselage tilts at a high angle, which can easily lead to a shift in the center of gravity or even tipping over. In view of this, we propose a horizontally adjustable base frame for landing of surveying UAVs. Utility Model Content

[0017] Compared with the prior art, this utility model provides a horizontally adjustable base for landing a surveying drone, which has the following beneficial effects:

[0018] 1. The surveying drone uses a horizontally adjustable base frame for landing. To prevent damage to the surveying module caused by the drone tilting, a support component is provided. When the drone lands on uneven ground, this component, together with the articulated frame, can rotate between the vertical limit frame and the tilt limit frame, causing the cylinder and support rod to adaptively adjust with the ground slope, ensuring that the rubber pad always keeps in contact with the ground. At the same time, the spring inside the cylinder absorbs the impact force of landing through the compression of the sliding rod. The sliding guide of the limit rod and the limit block in the limit groove prevents the sliding rod from shifting, ensuring the stability of the support.

[0019] 2. The horizontally adjustable base frame for landing of this surveying drone is equipped with a snap-fit ​​component to ensure the accuracy of the surveying results. This component, together with the snap-fit ​​design of the hook and long rod, allows for quick installation or removal of the surveying module. At the same time, the rubber rod absorbs flight vibrations through deformation, reducing the impact on the accuracy of the surveying module. Meanwhile, the elastic plate inside the bracket drives the clamping plate to fit tightly against the module, and together with the rigid support of the support frame, it ensures that the module does not loosen during flight and landing.

[0034] Please see Figures 1-8 This utility model provides a technical solution:

[0035] A horizontally adjustable base for landing a surveying drone includes a frame 1, a tail fin 2 fixedly mounted on the frame 1, a mounting rod 3 fixedly mounted on one end of the frame 1, a power unit 4 fixedly mounted on the other end of the mounting rod 3, and a propeller 5 fixedly mounted on the output end of the power unit 4.

[0036] In one embodiment of this utility model, a support assembly 6 is provided on the frame 1. The support assembly 6 includes a frame 61. The frame 61 is fixedly installed at the bottom of the frame 1. A connecting frame 62 is fixedly installed on the frame 61. A vertical limiting frame 63 and an inclined limiting frame 64 are fixedly installed on the connecting frame 62. A hinge frame 65 is hingedly installed on the connecting frame 62. A cylinder 66 is fixedly installed on the hinge frame 65. One end of a spring 67 is fixedly installed inside the cylinder 66. One end of a sliding rod 68 is fixedly installed on the other end of the spring 67. A support rod 69 is fixedly installed on the other end of the sliding rod 68. A rubber pad 610 is fixedly installed on the support rod 69. A rubber pad 610 is fixedly installed inside the cylinder 66. The limiting rod 611 has a limiting block 612 fixedly installed at the other end. The sliding rod 68 has a limiting groove 613 inside. There are multiple sets of connecting frame 62, vertical limiting frame 63, inclined limiting frame 64, hinge frame 65, cylinder 66, spring 67, sliding rod 68, support rod 69, rubber pad 610, limiting rod 611, limiting block 612 and limiting groove 613. The sliding rod 68 slides inside the cylinder 66, the spring 67 is set inside the cylinder 66, the limiting block 612 slides inside the limiting groove 613, the hinge frame 65 is set between the vertical limiting frame 63 and the inclined limiting frame 64, and the limiting rod 611 is set inside the spring 67.

[0037] In this embodiment, when the drone is in flight, the power unit 4 drives the propeller 5 to provide lift, and the support rod 69 of the support assembly 6 is in a natural hanging state. When the drone lands on uneven ground, the hinge frame 65 of the support assembly 6 rotates between the vertical limit frame 63 and the tilt limit frame 64, causing the cylinder 66, the slide rod 68 and the support rod 69 to adaptively adjust their angles according to the ground slope, so that the rubber pad 610 always keeps in contact with the ground, preventing the fuselage from tilting. The impact force of landing causes the slide rod 68 to compress the spring 67 inside the cylinder 66, and the elastic deformation of the spring 67 absorbs the impact force. At the same time, the limit block 612 on the limit rod 611 slides in the limit groove 613 of the slide rod 68 to prevent the slide rod 68 from deviating and ensure the stability of the support.

[0038] In one embodiment of this utility model, a buckle assembly 7 is provided on the frame 1. The buckle assembly 7 includes a mounting bracket 71. The mounting bracket 71 is fixedly installed at the bottom of the frame 1. A long rod 72 is fixedly installed on the mounting bracket 71. A hook 73 is snapped onto the long rod 72.

The bracket 710 and clamping plate 712 are arranged between multiple sets of cylinders 66. A surveying module is arranged between the bracket 710 and clamping plate 712.

[0039] In this embodiment, the surveying module is first placed between the bracket 710 and the clamping plate 712. The force generated by the deformation of the elastic plate 711 causes the clamping plate 712 to clamp the module. Then, the hook 73 is snapped onto the long rod 72 to complete the fixed installation of the surveying module. The rubber rod 75 can initially buffer possible vibrations. After the surveying task is completed, the hook 73 is released from the long rod 72, and the surveying module can be removed. The whole process is quick and convenient.
