[0002] Drones are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into the following categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders.

[0003] The card-mounted drone driver is a device used on a multi-rotor drone to drive the drone rotor to rotate. However, existing drone drivers are directly fixed to the preset structure of the drone (similar to the driver mounting shell in the present application) by bolts. When the drone is in use, its driving mounting mechanism is in direct contact with the external environment, which causes the bolts to rust. Therefore, when the drone driver is damaged, it is difficult to replace it. Moreover, after installation, the existing drone driver is wrapped inside the device, so the heat dissipation of the driver will be affected. Therefore, when it is used for a long time, the service life of the driver is affected. Summary of the invention

The driver body 5 is used to drive the rotor of the drone to rotate. A positioning convex plate 10 is installed on the outer wall of the driver body 5. The cross section of the positioning convex plate 10 is a semicircular structure. The driver installation shell 2 is arranged on the drone for matching the installation of the driver body 5. An inner convex limiting member 8 is installed on the inner wall of the driver installation shell 2. The inner convex limiting member 8 has a vertical limiting card slot 7.

[0035] The driver body 5 is sleeved inside the driver mounting housing 2, and the positioning protrusion 10 is slidably inserted into the limiting slot 7;

[0036] It also includes at least two sets of clamping mechanisms 1, which are arranged on the driver installation housing 2 and are used to lock the driver body 5 in the driver installation housing 2.

[0037] The clamping mechanism 1 includes a kit 104 and a pressure plate 105. The kit 104 is fixedly mounted on the outer wall of the driver mounting shell 2. A movable sheet 101 is movably mounted inside the kit 104. One end of the pressure plate 105 is mounted on the side of the movable sheet 101. The other end of the pressure plate 105 is inserted into the inner convex limiter 8 and clamped above the positioning convex plate 10.

[0038] The clamping mechanism 1 also includes a pull rod 102 and an elastic component 103. The elastic component 103 is made of a spring or a spring sheet. One end of the pull rod 102 is fixedly installed at the center position of one side of the movable sheet 101, and the other end of the pull rod 102 extends to the outside of the kit 104. The end of the pull rod 102 located outside the kit 104 has a spherical structure. The elastic component 103 is arranged inside the kit 104, one end of the elastic component 103 is fixed to the inner wall of the elastic component 103, and the other end is installed on the side of the movable sheet 101.

[0039] In this embodiment, the card-mounted UAV driver card-mounted method has the following specific card-mounted steps:

[0040] S1, insert the driver body 5 into the driver mounting housing 2, and during the inserting process, make the positioning protrusion 10 on the outer wall of the driver body 5 correspond to the limiting groove 7 on the inner convex limiting member 8;

[0041] S2. Push the driver body 5, and the positioning protrusion 10 slides in the limiting slot 7. When the positioning protrusion 10 contacts the pressure plate 105, pull the pull rod 102. At this time, the movable sheet 101 drives the pressure plate 105 to move until one end of the pressure plate 105 is completely moved out of the limiting slot 7. The driver body 5 can continue to move downward until the driver body 5 is completely entered into the driver installation shell 2. At this time, the bottom surface of the pressure plate 105 and the upper surface of the positioning protrusion 10 are on the same horizontal plane. Release the pull rod 102. Under the elastic force of the elastic component 103, one end of the pressure plate 105 moves to insert into the limiting slot 7 and presses on the top of the positioning protrusion 10, thus completing the installation of the driver body 5.

[0042] Example 2

[0043] On the basis of Example 1, in this embodiment, the inner wall of the driver mounting shell 2 is further provided with ribs 4, and there are two groups of ribs 4. The two groups of ribs 4 are symmetrically distributed in the driver mounting shell 2, and each group of ribs 4 is provided with multiple ribs. The multiple ribs 4 in the same group are equidistantly distributed. The ribs 4 are used to create a gap between the inner wall of the driver mounting shell 2 and the driver body 5, and the driver mounting shell 2 is provided with heat dissipation holes 3 for assisting the driver body 5.

[0044] By adopting the above technical solution:

[0045] The ribs 4 are arranged on the premise of ensuring the stability of the driver body 5 in the driver mounting shell 2, so that there is a gap between the driver body 5 and the driver mounting shell 2, and at the same time, heat dissipation holes 3 are opened on the driver mounting shell 2 to ensure the heat dissipation effect of the driver body 5 and improve its service life.

[0046] Example 3

[0047] On the basis of Example 1, in order to solve the problem that the UAV rotor is difficult to install after being damaged, in this embodiment, Figure 5-10 The figure also includes a rotor mounting mechanism, which is composed of a rotor assembly 6 and a locking mechanism, wherein the rotor assembly 6 is mounted on the top of the drive shaft 9 of the driver body 5, and the UAV rotor 20 is detachably mounted on the drive shaft 9 through the rotor assembly 6, and the rotor assembly 6 has a mounting cavity 14 inside;

[0048] The rotor assembly 6 adopts a cylindrical structure, and a plurality of slots 11 are provided at equal intervals on the edge of the upper surface of the rotor assembly 6. The locking mechanism is arranged inside the mounting cavity 14 to fix the drone rotor 20.

[0049] The locking mechanism includes a ring body 16 and a positioning rod 12. The positioning rod 12 is arranged parallel to the top of the ring body 16. The positioning rod 12 is an arc-shaped structure, and the center of the arc of the positioning rod 12 is coaxial with the circle of the ring body 16. The positioning rod 12 and the ring body 16 are both located in the installation cavity 14. One end of the positioning rod 12 is connected to the ring body 16 through a connecting rod 15, and the ring body 16 and the positioning rod 12 can rotate a certain angle in the installation cavity 14. When the ring body 16 rotates, one end of the positioning rod 12 can be inserted into the slot 11.

[0050] The locking mechanism also includes a lever 13 , which is symmetrically mounted below the ring body 16 . The bottom of the lever 13 extends to the outside of the rotor assembly 6 and is used to rotate the ring body 16 to control the extension and retraction of the positioning rod 12 .

[0051] The locking mechanism also includes a sleeve rod 18, which is arranged at one end of the positioning rod 12 and has a spring 17 sleeved on the sleeve rod 18. The elastic force of the spring 17 provides the locking mechanism with rotational power, so that in normal state, one end of the positioning rod 12 is inserted into the slot 11.

[0052] When the drone rotor 20 is installed (the matching assembly structure of the drone rotor 20 is as shown in FIG. Figure 9-10 As shown, a combination sleeve 21 is connected to the bottom of the drone rotor 20 through a vertical rod 19. The combination sleeve 21 adopts a cylindrical hollow structure. The interior of the combination sleeve 21 has a plug plate 22 that is adapted to the slot 11, and a locking hole 23 is provided on the plug plate 22. The combination sleeve 21 is put on the rotor assembly 6, and the combination sleeve 21 is selected so that the plug plate 22 is correspondingly inserted into the slot 11. During the insertion process, the ring body 16 is rotated by the lever 13 to shrink one end of the positioning plug rod 12 into the installation cavity 14. When the plug plate 22 is completely inserted into the slot 11, the lever 13 is released, and the ring body 16 is driven to rotate under the elastic force of the spring 17, so that the positioning plug rod 12 is inserted into the locking hole 23, and the assembly of the drone rotor 20 is completed. In this way, when the drone rotor 20 is damaged, it can be directly replaced to save costs.
