Technical Field

[0001] The utility model belongs to the technical field of icing detection, and particularly relates to an icing detector installed inside the equipment compartment of an unmanned aerial vehicle (UAV) wing. Background Art

[0002] Icing detection technology is applied to ensure the flight safety of an aircraft, detect the icing meteorological environment where the aircraft is located, calculate the icing rate, and output an icing warning signal.

[0003] The internal structures of existing icing detector products are mostly in a "pagoda" structure, and multiple circular circuit boards are used for circuit structure design inside, so that the space inside the cylindrical inner cylinder cannot be utilized to the maximum extent. Content of the Utility Model

[0004] In order to meet the user's requirements for space dimensions while ensuring the reliability of the mechanical structure, and to facilitate the product assembly, circuit connection, and function debugging processes, such a circular icing detector is designed.

[0005] The utility model provides an icing detector installed inside the equipment compartment of an unmanned aerial vehicle (UAV) wing. The icing detector includes a bracket inside, which includes an upper disc body, a lower disc body, an intermediate support plate and a circumferential support strip between the upper disc body and the lower disc body. A vibrator assembly and a windward heater assembly are installed at the upper end of the upper disc body and are encapsulated by an upper shell. The probe of the vibrator assembly penetrates through the upper shell; a lightning protection and filtering assembly is installed at the upper end of the lower disc body, a power supply filtering assembly is installed on one side of the intermediate support plate, and a drive circuit assembly is installed on the other side of the intermediate support plate. The two are directly electrically connected by plugging in a board-to-board connector; the lower side of the upper shell is encapsulated by a lower shell, and a connector is provided on the outer side of the lower shell.

[0006] Advantageously, the circuit boards of the power supply filtering assembly and the drive circuit assembly are installed on the intermediate support plate.

[0007] Advantageously, the circuit boards of the power supply filtering assembly and the drive circuit assembly are installed by means of screws or the cooperation of threaded rods and screws.

[0008] Advantageously, the windward heater assembly is installed at an eccentric and edge position of the upper shell and is separated from the vibrator assembly by a certain distance.

[0009] Advantageously, a connection structure is further provided on the outer side of the lower disc body.

[0010] Advantageously, the vibrator assembly is installed at the upper end of the upper disc body through a vibrator mounting cylinder.

[0011] Beneficial effects: Compared with traditional detectors, the internal structure of the present utility model adopts an integrated design bracket structure, enriching the types of internal structures of icing detectors and providing a new structural design solution to meet customer needs; the assembly design of the baffle, the outer cover and the base facilitates the electrical connection between the filter socket and the internal circuit board assembly of the product, and facilitates the operation of wiring harness bundling and fixing. Compared with the old structural design and assembly method, the installation work of multiple parts and circuit board assemblies of the product is reduced, and the work efficiency in the product assembly and debugging process can be increased several times compared with before.

[0012] The features, functions, and advantages discussed can be implemented independently in various examples or combined in other examples. Other details of the examples can be seen with reference to the following description and drawings. Description of the Drawings

[0013] When read in conjunction with the drawings, the examples, as well as the preferred modes of use, other purposes, and their descriptions, will be best understood by reference to the following detailed description of the examples of the present utility model, in which:

[0014] Figure 1 is a schematic structural diagram of the icing detector of the present utility model.

[0016] The disclosed examples will be described more fully with reference to the drawings, in which some (but not all) of the disclosed examples are shown. In fact, many different examples can be described and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete and will fully convey the scope of this disclosure to those skilled in the art.

[0017] See Figure 1 The cylindrical icing detector shown is installed inside the wing equipment compartment of the unmanned aerial vehicle. The upper housing 2 and the bracket 3 are fixed by bolts, and the lower housing 8 is installed on the lower side of the upper housing 2. A sealing strip and a sealing ring are provided at the connection between the upper housing 2 and the lower housing 8 to prevent the atmosphere containing acidic and salt components from entering the interior of the product and affecting the performance of the product. The bracket 3 includes an upper disk body, a lower disk body, and a support structure between the upper disk body and the lower disk body. The support structure includes a middle support plate and a peripheral support bar.

[0018] The circuit board assembly includes a power filter assembly 4 and a drive circuit assembly 7. The power filter assembly 4 is installed on one side of the middle support plate, and the drive circuit assembly 7 is installed on the other side of the middle support plate. The two are directly electrically connected through the inter-board connector. The power filter assembly 4 and the drive circuit assembly 7 are fixed to the middle support plate by screws, which can maximize the use of the space inside the cylindrical tube and reduce the number of circuit board parts. In another embodiment, in order to ensure the structural strength, the two circuit boards are installed using threaded rods and screws, which has a simple structure, is easy to disassemble and assemble, and is easy to maintain.

[0019] The vibrator assembly 9 is accommodated in the upper shell 2 and is mounted on the upper plate at the lower end, and a lightning protection filter assembly 6 is mounted on the lower plate. The windward surface heater assembly 10 is mounted at an eccentric edge position of the upper shell 2 and is separated from the vibrator assembly 9 by one end, so that the windward surface and the probe 1 at the upper end of the vibrator assembly 9 can be heated separately. In this embodiment, the vibrator assembly 9 also has a vibrator mounting tube for mounting and protecting the vibrator assembly and fixing the windward surface heater assembly 10.

[0020] Descriptions of different advantageous arrangements have been presented for purposes of illustration and description, but the description is not intended to be exclusive or limited to examples of the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art.
