[0042] The following will further elaborate on the embodiments of the present utility model in conjunction with the accompanying drawings.

[0043] Refer to Figures 1 to 7, in a first aspect, an embodiment of the present utility model provides a selection and testing device for UAV components, including:

[0044] A control module; a frame 100, on which a motor to be tested 200 is detachably installed, and a propeller to be tested 300 is detachably installed on the output shaft of the motor to be tested 200; a lift detection module is electrically connected to the control module, and the lift detection module is used to detect the lift provided by the propeller to be tested 300 when the motor to be tested 200 operates; a rotation speed detection module, including a transmitting component 410, a receiving component 420, and a reflecting component 430; the transmitting component 410 and the receiving component 420 are respectively electrically connected to the control module; the reflecting component 430 is arranged on the side of the propeller to be tested 300 close to the frame 100, and the transmitting component 410 and the receiving component 420 are both arranged on the frame 100 at positions opposite to the reflecting component 430.

[0045] It should be noted that Figure 1 The schematic diagram of the module of the selection and testing device for UAV components provided by the embodiment of the present utility model. In the present utility model, the frame 100 simulates the fuselage of the UAV, and the weight and shape of the frame 100 can be set arbitrarily according to requirements. The motor to be tested 200 and the propeller to be tested 300 are both detachable, which is convenient for testers to quickly replace the motor to be tested 200. Further, the control module can use components such as an MCU (microprocessor) that can maintain the operation of the system for MCU sampling; specifically, the MCU circuit is as Figure 3 shown. U3 and peripheral components form a single-chip microcomputer small system, communicate with various sensors to process the data provided by various sensors, and display the calculated data on the TFT screen. J10 is a programming port. Referring to Figure 4 , in the embodiment of the present utility model, the lift detection module uses a gravity sensor 500 and is arranged on the frame 100. Further, the propeller to be tested 300 is horizontally arranged on the frame 100. When the motor to be tested 200 operates to drive the propeller to be tested 300 to rotate, a thrust will be generated in the direction of the propeller to be tested 300, thereby causing the detection value of the gravity sensor 500 to change. According to the change of the detection value, the pulling force of the motor to be tested 200 on the propeller to be tested 300 under the current parameters is detected in real time; it can be understood that for the specific setting of the orientation of the propeller to be tested 300, it only needs to be able to generate a thrust in the horizontal direction when the propeller to be tested 300 rotates. Further, the rotation speed detection module is used to detect the rotation speed of the propeller to be tested 300. In the embodiment of the present utility model, the transmitting component 410 and the receiving component 420 use infrared transmitting and receiving tubes (which can be integrally formed or as Figure 2(separately arranged as shown), the infrared emission and reception tube is a component that can both emit and receive infrared light; the reflection component 430 uses a reflective paper attached to the side of the blade 300 to be measured facing the frame 100. It can be understood that the number and position of the reflective paper can be set arbitrarily according to requirements; when the blade 300 to be measured rotates, the infrared emission tube continuously emits infrared light towards a fixed area. When the infrared light propagates to this fixed area, if the reflective paper on the blade 300 to be measured is in this area at this time, the reflective paper will reflect the infrared light back to the infrared reception tube; when the reception tube receives the infrared light reflected by the reflective paper, it means that the blade 300 to be measured has rotated one circle, and the rotation speed of the blade 300 to be measured can be detected in real time based on this.

[0046] Referring to Figure 7 , in some embodiments of the present invention, the test device further includes a drive circuit, and the drive circuit is electrically connected to the control module and the motor 200 to be measured respectively, and the drive circuit is used to drive the motor 200 to be measured to work.

[0047] It should be noted that the drive circuit can drive the motor 200 to be measured to work by inputting a fixed voltage and then setting the duty cycle of the PWM of the motor 200 to be measured. As Figure 7 shown, the working principle of the drive circuit driving the motor 200 to be measured is: the J2 terminal is electrically connected to the brushed motor, D10 is a freewheeling diode, and C23 is a filter capacitor. The MCU outputs a PWM wave, and the PWM wave passes through the current-limiting resistor R14 to control the turn-off of U8 and U2. When U2 and U8 are turned on, the motor 200 to be measured rotates.

[0048] Referring to Figure 8 , in some embodiments of the present invention, the test device further includes a temperature detection module, and the temperature detection module is electrically connected to the control module; the temperature detection module is attached to the surface of the motor 200 to be measured.

[0049] It should be noted that the temperature detection module is used to detect the real-time temperature when the motor 200 to be measured is running, and the temperature sensor is mounted on the surface of the motor to obtain the temperature of the motor in real time. As Figure 8 shown, the NTC temperature sensor is used in the embodiment of the present invention. The value obtained by dividing the 3.3V voltage by the NTC temperature sensor through the resistor R6 (the thermistor value changes with temperature change) is transmitted to the MCU, and the MCU converts these analog values through ADC, and then displays the converted temperature value on the TFT screen of the display screen module in real time.

[0050] Referring to Figure 9 , in some embodiments of the present invention, the test device further includes a voltage detection module, and the voltage detection module is electrically connected to the motor 200 to be measured and the control module respectively; the voltage detection module is used to detect the voltage when the motor 200 to be measured is working.

[0051] It should be noted that the voltage detection module is used to detect the working voltage of the motor 200 to be tested during operation. As Figure 9 shown, after the external voltage B+ is divided by R4 and R5 and filtered by C12, the corresponding analog value is transmitted to the MCU. The MCU converts these analog values through ADC conversion and then displays the values on the TFT screen of the display module in real time.

[0052] Referring to Figure 10 , in some embodiments of the present invention, the test device further includes a current detection module. The current detection module is electrically connected to the motor 200 to be tested and the control module respectively; the current detection module is used to detect the current of the motor 200 to be tested during operation.

[0053] It should be noted that the current detection module is used to detect the working current of the motor 200 to be tested during operation. As Figure 10 shown, after the driving circuit works on the motor 200 to be tested, a relatively weak voltage will be generated on the current sampling resistor R16. The voltage is then input to the operational amplifier U1 through the current limiting resistor R12. The amplified voltage is filtered by R11 and C5 and then transmitted to the MCU. The MCU converts the voltage into current through internal calculation and then displays the current value on the TFT screen of the display module in real time.

[0054] Referring to Figure 11 , in some embodiments of the present invention, the test device further includes an operation button. The operation button is electrically connected to the control module.

[0055] It should be noted that, as Figure 11 shown, the operation button provided in the embodiment of the present invention is used to adjust the PWM duty cycle of the motor 200 to be tested and to adjust the system menu displayed on the display module.

[0056] Referring to Figure 12 , in some embodiments of the present invention, the test device further includes a display module; the display module includes a TFT display screen, and the TFT display screen is electrically connected to the control module.

[0057] It should be noted that the display module is used to display various parameters during the test process of the test device. In one embodiment of the present invention, a TFT display screen is used. As Figure 12 shown, the J1 terminal is externally connected to the TFT screen, and the MUC drives this display screen through SPI.

[0058] Referring to Figure 13 , in some embodiments of the present invention, the test device further includes a power supply module; the power supply module includes a low dropout linear regulator, and the low dropout linear regulator is electrically connected to an external power supply; the low dropout linear regulator is used to convert the external power supply into the supply voltage of the test device.

[0059] It should be noted that, as Figure 13 shown, the J3 terminal is connected to an external power supply. U4 is an LDO that converts the input power supply of the external power supply into an output voltage of 3.3V to supply power to the circuit of the entire test device.

[0060] The following is a specific embodiment of the present invention:

[0061] Referring to Figures 1 to 13 , when it is necessary to test whether the motor 200 to be tested and the blade 300 to be tested are reasonably selected, first input a fixed voltage of 3.3V through the power supply module, set the duty cycle of the PWM by operating the button, such as 30%, 50%, 80%, the MCU outputs the PWM, and drives the brushed motor 200 to be tested through the motor drive circuit. At this time, the blade 300 to be tested rotates, generating a pulling force acting in the horizontal direction. The MCU monitors the working current, working voltage, temperature of the motor 200 to be tested, pulling force provided by the blade 300 to be tested, and rotational speed of the blade 300 to be tested in real time and displays them on the TFT screen respectively. The tester can select the best motor and blade suitable for the UAV design through comparative tests of several groups of motors or blades.

[0062] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the above implementation manners.
