[0002] A circuit board for a drone refers to a circuit board used in a drone to connect and control various electronic components. It consists of multiple electronic components and wires. The most core part of the circuit board for a drone is the control circuit chip, which is responsible for controlling and scheduling the work of various parts of the drone, including GPS navigation, servos, motors, etc. The microprocessor on the control circuit uses a series of algorithms and control technologies to control the flight of the drone, real-time acquire and process information from various sensors, and execute instructions, so as to achieve the stability and safety of the drone flight. When designing and manufacturing a drone, the performance and quality of the circuit board for a drone are crucial. In the process of using existing circuit boards, in order to reduce the overall weight of the drone and improve its flight performance, most circuit boards may adopt a thin and light design, but this may reduce its structural strength and stability, and reduce the safety of the drone in extreme situations. Therefore, we propose a circuit board for a drone to solve the problems raised above. Content of the Utility Model

[0003] To overcome the problem that in the process of using existing circuit boards, in order to reduce the overall weight of the drone and improve its flight performance, most circuit boards may adopt a thin and light design, but this may reduce its structural strength and stability, and reduce the safety of the drone in extreme situations.

[0004] The technical solution of the utility model is: a circuit board for a drone, comprising a circuit board body, a protection board and a mounting board; a protection board for protecting the circuit board body from being damaged when subjected to external impact is provided above the circuit board body, and a mounting board for driving the circuit board body to be fixedly installed with the drone to prevent the circuit board body from shifting due to the vibration of the fuselage during the flight of the drone is provided below the circuit board body.

[0005] Preferably, first fix the mounting plate to the inside of the drone by screwing through the fixing holes. Then pick up the circuit board body. The square clamping posts drive the mounting plate to be positioned and connected to the circuit board body through the square clamping slots. Then, according to the angle and distance of the mounting plate from the first mounting hole, by lifting the telescopic column, the telescopic column rotates to a suitable angle through the connecting rotating shaft with the mounting plate. Then, through the adjustment of the pin, the telescopic sleeve drives the mounting ring sleeve to move to a suitable length along the telescopic column, so that the mounting ring sleeve aligns with the first mounting hole. After confirmation, the pin passes through the telescopic sleeve and is positioned and connected to the telescopic column through the positioning hole. Then, screw the screws through the first connection hole and the second connection hole to fix the telescopic column and the telescopic sleeve to the inside of the drone, thereby preventing the circuit board from shifting due to the vibration of the fuselage during the flight of the drone.

[0006] Preferably, first mounting holes for bolts to pass through are respectively provided at the corners of the circuit board body. An annular clamping groove for positioning and connecting the protective plate is provided around the first mounting hole on the upper side of the circuit board body.

The annular clamping groove facilitates the positioning and connection of the circuit board body and the protective plate, and the square clamping slot facilitates the positioning and connection of the circuit board body and the mounting plate, improving the stability of the drone circuit board structure.

[0007] Preferably, a plurality of groups of heat dissipation holes for ventilation and heat dissipation during the operation of the circuit board body are provided around the middle of the protective plate. Second mounting holes for bolts to pass through are provided at the corners of the protective plate corresponding to the first mounting holes. First, drive the protective plate to be positioned and connected to the circuit board body through the annular clamping groove by the annular clamping plate.

An annular clamping plate is installed at the lower end of the protective plate where the second mounting hole is provided. A shock-absorbing soft pad is installed at the position of the lower end of the protective plate close to the annular clamping plate. If the drone is impacted by an external object during flight, the shock-absorbing blocks can reduce the impact force on the drone. At the same time, the shock-absorbing soft pad can buffer to avoid damage to the circuit board body when the protective plate is pressed down by force, improving the safety of the drone in extreme situations.

[0009] Preferably, fixing holes for screws to pass through are arranged in a rectangular array in the middle of the mounting plate. Square clamping posts are installed at positions near the corners at the upper end of the mounting plate. The square clamping posts drive the mounting plate to be positioned and connected with the circuit board body through square clamping grooves. First, the mounting plate is fixedly connected to the inner side of the drone by passing screws through the fixing holes. Then, pick up the circuit board body, and the square clamping posts drive the mounting plate to be positioned and connected with the circuit board body through square clamping grooves.

An installation ring sleeve is installed at one end of the telescopic sleeve away from the telescopic column. Then, according to the angle and distance of the mounting plate from the first installation hole, by lifting the telescopic column, the telescopic column rotates to a suitable angle with the mounting plate through the connecting rotating shaft. Then, through the adjustment of the pin, the telescopic sleeve drives the installation ring sleeve to move to a suitable length along the telescopic column, so that the installation ring sleeve is aligned with the first installation hole.

Then, the screws pass through the first connection holes and the second connection holes, and the telescopic column and the telescopic sleeve are fixedly connected to the inner side of the drone, thereby preventing the circuit board from shifting due to the vibration of the fuselage during the flight of the drone.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Different from the situation in the past that in the process of using the circuit board, in order to reduce the overall weight of the drone and improve the flight performance, the circuit board may mostly adopt a thin and light design, but this may reduce its structural strength and stability and reduce the safety of the drone in extreme situations.

Then, the screws pass through the first connection holes and the second connection holes, and the telescopic column and the telescopic sleeve are fixedly connected to the inner side of the drone, thereby preventing the circuit board from shifting due to the vibration of the fuselage during the flight of the drone.

[0014] 2. After the circuit board body is installed on the drone, first drive the protection board through the annular clamping plate to be positioned and connected to the circuit board body through the annular clamping groove. Then, during the operation of the drone circuit board, a large amount of heat will be generated, which can be ventilated and dissipated through the heat dissipation holes to avoid heat accumulation and affect the circuit components inside the circuit board body. If the drone is impacted by external objects during flight, the shock-absorbing block can reduce the impact force on the drone, and at the same time, the shock-absorbing soft pad can buffer to avoid damage to the circuit board body when the protection board is pressed down by force.
