Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV flight control shielding cabin device that resists strong electromagnetic interference. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aerial vehicles controlled by remote control or autonomous programs. They consist of four main parts: the fuselage, the power system, the flight control module, and the mission payload. Their control system includes a flight control computer, GPS positioning, and a remote controller, which enables attitude adjustment and flight path planning.

[0003] The drone flight controller is the core control system of a drone, equivalent to the "brain" of the drone. It is responsible for flight attitude stabilization, navigation control and mission execution. Existing drone flight controllers are directly installed on the circuit board inside the drone body and protected by a plastic shell. They have no shielding structure and are susceptible to external electromagnetic interference.

[0004] Therefore, a UAV flight control shielding cabin resistant to strong electromagnetic interference is proposed. A Faraday cage structure is constructed by using a conductive coating and a metal mesh grid, which can resist high-intensity electromagnetic interference. An anti-electromagnetic interference device can be used to prevent signal electromagnetic interference and ensure signal transmission. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a UAV flight control shielding cabin that resists strong electromagnetic interference. The Faraday cage structure is constructed using a conductive coating and a metal mesh, which can resist high-intensity electromagnetic interference. Furthermore, an electromagnetic interference suppressor can prevent signal electromagnetic interference and ensure signal transmission.

[0006] This utility model provides a drone flight control shielding cabin that resists strong electromagnetic interference, including a protective shell and a heat absorption plate. An anti-electromagnetic interference device is embedded inside the protective shell, a heat dissipation component is provided at the bottom of the protective shell, and a reserved slot is provided at the top of the protective shell.

[0007] The top of the reserved groove is fixed to the cover plate with bolts. A conductive coating is provided on the inner side of the reserved groove and the bottom of the cover plate. A sponge pad is glued to one side of the conductive coating, and a metal mesh is provided between the sponge pad and the conductive coating.

[0008] Optionally, the wiring terminals of the electromagnetic interference suppressor are located inside the reserved slot, and a heat-absorbing plate is fixed to the bottom of the reserved slot by bolts. The heat-absorbing plate is made of graphene material.

[0009] Optionally, the heat dissipation assembly includes a ventilation box fixed to the bottom of the protective housing by bolts, a heat-conducting plate is equidistantly sleeved on the top of the ventilation box, the top of the heat-conducting plate penetrates through the protective housing, and the top of the heat-conducting plate is fixed to the bottom of the heat-absorbing plate by bolts.

[0010] Optionally, an exhaust fan is equidistantly mounted inside the heat-conducting plate via a mounting bracket, and the heat-conducting plate is made of metallic copper.

[0011] Optionally, one end of the ventilation box has an air inlet, and a dustproof mesh is fixed inside the air inlet with bolts. The other end of the ventilation box has an air outlet, and a protective mesh is fixed inside the air outlet with bolts.

[0013] As can be seen from the above technical solution, the UAV flight control shielding cabin that resists strong electromagnetic interference provided by this utility model achieves the purpose of resisting strong interference through the setting of conductive coating, metal mesh and anti-electromagnetic interference device.

[0014] The beneficial effects of this utility model are:

[0015] 1. The UAV flight control shielding cabin for resisting strong electromagnetic interference described in this utility model is constructed with a conductive coating and a metal mesh to form a Faraday cage structure, which can resist high-intensity electromagnetic interference.

[0030] Optionally, the heat dissipation assembly 2 includes a ventilation box 207 fixed to the bottom of the protective housing 1 by bolts. A heat-conducting plate 201 is equidistantly sleeved on the top of the ventilation box 207. The top of the heat-conducting plate 201 penetrates the protective housing 1 and is fixed to the bottom of the heat-absorbing plate 6 by bolts.
