[0027] Example 1:

[0028] A coaxial twin-propeller motor mount includes a motor mount body 1, wherein:

[0029] The motor base body 1 is a cylindrical shape with openings at both ends, and two motors 2 are respectively inserted into the two ports of the motor base body 1;

[0030] A ducted fan 3 is fitted into the opening on the side wall of the motor base body 1.

[0031] In the above structure, the motor base body is a cylinder open at both ends; a ducted fan is fitted into the opening in the side wall of the motor base body, through which air enters and exits through the openings at both ends of the motor base body. By fitting the ducted fan into the opening in the side wall of the motor base body, airflow enters the motor base body through the ducted fan and flows out through both ends, carrying away the heat of the motor and enhancing the heat dissipation performance of the motor base.

[0032] The motor mounting body has motor mounting cavities located on both sides of the ducted fan, and the motor 2 is installed inside the motor mounting cavity. The motor is located inside the motor mounting cavity, and the built-in structure improves the protection of the motor.

[0033] The motor base body has air hoods at both ends.

[0034] A ring-shaped connector is fixedly provided on the inner wall of the motor base body 1, and the ring-shaped connector is connected to the temperature control plate 8 by bolts. The temperature control plate 8 is an integrated circuit board, which is located in the inner wall of the motor base body 1 and connected by the ring-shaped connector, thereby improving its stability and safety during operation.

[0035] One end of the aforementioned temperature control board 8 is electrically connected to the aforementioned ducted fan 3, and the other end of the aforementioned temperature control board 8 is electrically connected to the aforementioned motor. The aforementioned temperature control board 8 is used to control the ducted fan 3 to adjust the air intake volume. The temperature control board 8 receives temperature information from the motor and adjusts the air intake volume of the ducted fan 3 accordingly.

[0036] The motor is equipped with a female locking pin 4, and the motor mount body 1 has male locking pins 5 at both ends. The motor mount body 1 and the motor are connected by the female locking pin 4 and the male locking pin 5. The quick-connect fitting formed by the female locking pin 4 and the male locking pin 5 makes the connection between the motor mount body 1 and the motor more convenient and faster. The simple structure of the motor mount body 1 reduces the processing cost and difficulty.

[0037] The aforementioned motor is a non-magnetic steel motor equipped with a centrifugal fan. The motor and centrifugal fan are concentric and coaxial; as the motor rotates, the centrifugal fan also rotates, enhancing ventilation and heat dissipation. The motor contains a rotor spindle, with a rotor disc at the top. A heat sink is fitted over the rotor disc, and multiple circumferential heat dissipation vents extend into the motor. Multiple heat dissipation pipes are installed on the heat sink, with all inlets connected to all heat dissipation vents, and outlets located at the bottom of the heat sink. By installing a heat sink on the outside of the rotor disc, the centrifugal radius of the rotor disc is increased, thus increasing the centrifugal airflow. Furthermore, placing the heat sink outlet at the bottom prevents dust intrusion.

[0038] The motor base body 1 is provided with a light panel 6 on its side wall. The light panel 6 is used to display the reaction status of the ducted fan 3.

[0039] The motor mount body 1 has an arm connection end 7 on its side wall, which is plugged into the drone arm. The arm connection end 7 is electrically connected to the drone arm, providing power to the motor through the drone arm.

[0040] Also provided is a drone, including the aforementioned coaxial dual propeller motor mount.

[0041] Specifically, the aforementioned motor mount body is a cylindrical shape with openings at both ends, and two motors are respectively inserted into the two ports of the motor mount body; a ducted fan 3 is fitted into the opening on the side wall of the motor mount body. By making the motor mount body a cylindrical shape with openings at both ends and inserting the two motors into the two ports of the motor mount body, the motors can be enclosed by the motor mount, preventing damage to the motors due to the ingress of foreign objects and dust, and enhancing the stability of the motors; the addition of the ducted fan 3 allows air to enter through the ducted fan 3 and exit through the motor, carrying away the heat of the motor through air cooling, thus achieving a heat dissipation function. At the same time, because the motor and the centrifugal fan are concentric and coaxial, the motor drives the centrifugal fan to rotate while rotating, further enhancing the heat dissipation of the motor. A temperature control board 8 is set in the motor mount body, which senses the motor temperature and controls the ducted fan 3 to adjust the air intake, making temperature regulation more intelligent; the addition of a locking female head 4 and a locking male head 5 makes the connection between the motor mount body and the motor more convenient and quick. Furthermore, the motor mount body has a simple structure and is easy to manufacture.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
