Technical Field

[0001] The utility model relates to the technical field of surveying and mapping drones, and particularly relates to a take-off and landing mechanism for a surveying and mapping drone. Background Art

[0002] With the increasing maturity of drone technology, its application in the field of surveying and mapping is becoming more and more extensive. Drone surveying and mapping refers to the theory and technology that comprehensively integrates multi-disciplinary technologies such as drone aircraft, remote sensing sensors, telemetry and remote control, communication, navigation and positioning, and image processing. By obtaining the geographical spatial information of the target area in real time, it can quickly complete remote sensing data processing, surveying and mapping, environmental modeling and analysis. Drone aerial surveying and mapping has the advantages of high accuracy, high efficiency, and the ability to analyze data.

[0003] When using a drone for surveying and mapping, the drone needs a stable and flat platform for take-off and landing. At present, most take-off and landing mechanisms are supported by four corners. In the wild area with a large slope, it is difficult to find a flat terrain of the same size as the take-off and landing platform, and the take-off and landing platform is difficult to disassemble and store, so the portability is not good.

The support member 1 is composed of a cylindrical tube in the middle connecting a ground supporting ring 1.1 at the lower side and a frustum 1.2 at the upper side. An external thread 1.3 is provided on the outer wall of the cylindrical tube. Hinged rods 3 are evenly hinged around the axis of the frustum 1.2. A landing plate 4 can be horizontally installed on the frustum 1.2 and the hinged rods 3. The lower end of the hinged rod 3 is hinged with an inner support rod 5, and a locking nut 6 that can lock the inner support rod 5 is screwed on the external thread 1.3.

[0006] Further, the lower end of the ground inserting member 2 is in a sharp cone shape.

[0007] Further, the number of the landing plates 4 is four, and the diagonal corners of the landing plates 4 are respectively installed on the hinged rods 3 and the frustum 1.2.

[0010] Further, a rubber pad that abuts against the inner support rod 5 is provided inside the upper end of the lock nut 6.

[0011] The advantages of the present utility model are as follows: After the ground inserting member is inserted into the ground, the ground supporting ring fits the ground to form a support, and only a flat ground with the size of the ground supporting ring is required. Moreover, it is convenient to disassemble and store; the ground inserting member with a tapered shape is easy to insert into the ground; the take-off and landing plate can be disassembled, and the hinge rod and the inner support rod can be retracted for easy taking and storage; when the inner support rod is locked by the lock nut and propped up, the hinge rod is flush with the upper end surface of the frustum, and the take-off and landing plate can be installed on the hinge rod and the frustum to form a square take-off and landing platform; when the inner support rod is propped up, one end of the inner support rod is received in the receiving groove, and after the lock nut locks the inner support rod, the inner support rod fits against the upper end surface of the receiving groove, and the inner support rod is respectively limited on the upper and lower sides by the receiving groove and the lock nut; the rubber pad has elasticity and friction, is not easy to damage the inner support rod, and can firmly lock the inner support rod.

[0017] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0018] Refer to Figures 1 to 5, the present utility model provides a take-off and landing mechanism for a surveying and mapping unmanned aerial vehicle, which includes a support member 1 and a ground inserting member 2 connected to the lower end of the support member 1. The lower end of the ground inserting member 2 is in a sharp cone shape, and the sharp cone-shaped ground inserting member is easy to insert into the ground. The support member 1 is composed of a middle cylinder connecting a ground supporting ring 1.1 at the lower side and a frustum 1.2 at the upper side. After the ground inserting member is inserted into the ground, the ground supporting ring fits on the ground to form a support. It is only necessary to find a flat ground with the size of the ground supporting ring or level the flat ground, without the need to find a flat ground with the size of the take-off and landing platform. An external thread 1.3 is provided on the outer wall of the cylinder. Hinged rods 3 are evenly hinged around the axis of the frustum 1.2. A take-off and landing plate 4 can be horizontally installed on the frustum 1.2 and the hinged rods 3. The lower end of the hinged rod 3 is hinged with an inner support rod 5. A locking nut 6 that can lock the inner support rod 5 is screwed on the external thread 1.3. The take-off and landing plate can be detached, and the hinged rod and the inner support rod can be retracted for easy taking and storage. By screwing the locking nut, the inner support rod can be locked (the locking nut is upward), so that the inner support rod supports the hinged rod (the upper end surface of the hinged rod is flush with the upper end surface of the frustum). After detaching the take-off and landing plate, unscrewing the locking nut in the reverse direction can loosen the inner support rod (the locking nut is downward), and the hinged rod and the inner support rod can be folded up.

[0019] The number of the take-off and landing plates 4 is four, and the diagonal corners of the take-off and landing plates 4 are respectively installed on the hinged rods 3 and the frustum 1.2. When the inner support rod is locked and supported by the locking nut, the hinged rod is flush with the upper end surface of the frustum, and the take-off and landing plate can be installed on the hinged rod and the frustum, thus forming a square take-off and landing platform. The take-off and landing plate can be detached and folded up, occupying a small space and being convenient to take.

[0020] Refer to Figure 4 , Figure 5 , a receiving groove 1.4 that can accommodate the inner support rod 5 and extends to the external thread 1.3 is provided on the outer wall of the cylinder. The supported inner support rod 5 fits on the upper end surface of the receiving groove 1.4. When the inner support rod is supported, one end of the inner support rod is received in the receiving groove, and after the locking nut locks the inner support rod, the inner support rod fits on the upper end surface of the receiving groove. The inner support rod is respectively limited on the upper and lower sides by the receiving groove and the locking nut.

[0021] A plum blossom-shaped protrusion is provided on the outer ring of the locking nut 6. The plum blossom-shaped protrusion is convenient for the staff to screw the locking nut.

[0022] A rubber pad that abuts against the inner support rod 5 is provided on the inner side of the upper end of the locking nut 6. The rubber pad has elasticity and friction, is not easy to damage the inner support rod, and can firmly lock the inner support rod.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
