Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle arrival detection device. Background Art

[0002] With the rapid development of drone technology and the increasing number of applications, people are increasingly demanding drones that can perform continuous intelligent operations, especially in the fields of line inspection, emergency response, topographic surveying, etc.; currently, existing drones on the market are controlled by pilots and the batteries are manually replaced to continue the flight mission, which greatly reduces the efficiency of drone operations. Therefore, designing a set of intelligent charging structures and systems to achieve intelligent control of the entire process can greatly improve the operating efficiency, but when the aircraft lands on the machine nest, it is very critical to confirm whether the aircraft has landed accurately at the designated location, so it is necessary to develop a drone in-place detection mechanism.

[0003] At the same time, most aircraft on the market use push rods in the X-axis and Y-axis directions to achieve positioning. This solution can easily cause deformation of the aircraft's support legs and affect the accuracy of charging and plugging. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a drone in-place detection device, which does not need to be driven by an external active power device and can achieve the effect of drone parking in-place detection.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A drone arrival detection device is used to determine whether the drone has landed accurately on the aircraft landing platform.

[0007] The bottom of the drone has a contact piece;

[0008] A contact micro switch is installed on the top of the aircraft landing platform;

[0009] When the UAV is guided to land at a designated position of the aircraft landing platform, the contact element continuously presses the trigger position of the contact micro switch.

[0010] Preferably, the contact piece is a charging contact for charging a battery inside the drone.

[0011] Preferably, the aircraft landing platform further comprises a wiring harness fixing bracket, the contact micro switch is connected with a micro switch signal line, and the micro switch signal line is installed on the aircraft landing platform through the wiring harness fixing bracket.

[0012] Preferably, the micro switch signal line is against the side of the aircraft landing platform.

[0013] Preferably, the top of the contact microswitch has a plate-shaped triggering member, which is connected to the triggering position of the contact microswitch so that the contact member has a contact tolerance.

[0014] Preferably, the contact piece protrudes from the lower part of the main body of the drone.

[0015] Preferably, the lower part of the drone and the top of the aircraft landing platform have mutually cooperating guiding components.

[0016] Preferably, the top of the aircraft landing platform has a funnel-shaped guide, and the lower part of the drone has a rod-shaped drone landing foot.

[0017] The beneficial effects of using the utility model are:

[0018] The UAV arrival detection device cooperates with the contact micro switch installed on the top of the aircraft landing platform through the contact piece under the UAV. When the UAV is guided by the guide assembly and lands at the designated position of the aircraft landing platform, the contact piece suppresses the trigger position of the contact micro switch, so that the contact micro switch generates an arrival signal to form a basis for judging whether the UAV has landed in place. The UAV arrival detection device has a simple structure, sophisticated design, and high judgment accuracy, and is particularly suitable for use in intelligent and modular UAV libraries.

[0023] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0024] In order to solve the problem of the detection and landing accuracy of the drone 1 in the prior art, Figure 1As shown, this embodiment proposes a drone arrival detection device. Specifically, a drone arrival detection device includes a contact piece installed at the bottom of the drone 1, and a contact micro switch 3 installed on the top of the aircraft landing platform. When the drone 1 lands and parks on the top of the aircraft landing platform and parks in place, the drone 1 is guided to park at a specified position of the aircraft landing platform, and the contact piece continuously suppresses the trigger position of the contact micro switch 3. At this time, the contact micro switch 3 continuously generates a trigger arrival signal. When the aircraft landing platform receives the arrival signal, it can be determined that the drone 1 has been parked in place.

[0025] Combination Figure 2 As shown, specifically, in this embodiment, the bottom of the drone 1 has a plurality of rod-shaped drone landing feet 7, and the top of the aircraft landing platform has a funnel-shaped guide 6. When the drone 1 moves to the top of the aircraft landing platform, it continues to slowly descend until the drone landing feet 7 fall into the guide 6. At this time, the drone landing feet 7 contact the inner conical surface of the guide 6, and the drone landing feet 7 gradually slide down in the conical surface until the drone landing feet 7 slide to the lower gathering end of the guide 6. At this time, the drone 1 is relatively in place. At this time, it is necessary to judge whether the drone 1 is accurately in place, such as the contact member presses the contact micro switch 3 and generates an in-place signal, that is, it is judged that the drone 1 has landed in place.

[0026] Preferably, the lower part of the drone landing foot 7 has a universal sliding member, which is a ball bearing in this embodiment.

[0027] On the aircraft landing platform, the contact micro switch 3 is installed on the side of the aircraft landing platform. A wire harness fixing bracket 4 is also installed on the side of the aircraft landing platform near the contact micro switch 3. The micro switch signal line 5 that transmits the position signal of the contact micro switch 3 is fixed by the wire harness fixing bracket 4 and is attached to the main body of the aircraft landing platform to reduce space occupancy.

[0028] Preferably, the contact piece is a charging contact 2 for charging the internal battery of the drone 1. When the charging contact 2 presses the contact micro switch 3, the charging head on the aircraft landing platform is plugged into the charging contact 2, that is, the battery in the drone 1 is electrically connected to the power supply component of the aircraft landing platform, thereby charging the internal battery of the drone 1.

[0029] like Figure 2 As shown, the contact microswitch 3 has a plate-shaped trigger member 8 on the top, and the trigger member 8 is connected to the trigger position of the contact microswitch 3 so that the contact member has contact tolerance. After the charging contact 2 presses the plate-shaped trigger member 8, even if it is slightly misaligned, the contact microswitch 3 can form a trigger effect, avoiding the formation of point detection when the drone 1 is in place, that is, achieving the contact tolerance of the in-place detection.

[0030] The drone in-place detection device cooperates with the contact micro switch 3 installed on the top of the aircraft landing platform through the contact piece under the drone 1. When the drone 1 is guided by the guide component and lands at the designated position of the aircraft landing platform, the contact piece suppresses the trigger position of the contact micro switch 3, so that the contact micro switch 3 generates an in-place signal to form a basis for judging whether the drone 1 has landed in place. The drone in-place detection device has a simple structure, a sophisticated design, and a high judgment accuracy, and is particularly suitable for use in an intelligent and modular drone 1 library.

[0031] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
