[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figure 4 and Figure 5 This utility model provides a zoom component for an external lens of a drone, including a base bushing 1, with a lens 6 disposed at the end of the base bushing 1. The base bushing 1 includes an end cap 11, with a plurality of equally spaced mounting holes 12 on the outer wall of the end cap 11. An integrally formed sleeve 13 is fixedly disposed on one side of the outer wall of the end cap 11. Sliding grooves 14 are provided on both sides of the inner wall of the sleeve 13. A threaded head 15 is provided at the end of the sleeve 13 away from the end cap 11. A through guide channel 16 is provided on the top outer wall of the sleeve 13.

[0026] In this embodiment, the core tube 5 is rotatably sleeved on the outside of the sleeve 13, and the sleeve 13 serves as the shaft for the rotation of the core tube 5. The follower block 71 of the zoom lens 7 is slidably inserted into the inside of the guide channel 16, and the slider 72 is slidably inserted into the inside of the groove 14.

[0027] Please see Figures 3-6The core tube 5 is rotatably sleeved on the outside of the base bushing 1. The core tube 5 rotates outside the base bushing 1 through the drive module 4. The shifting mechanism 3 drives one of its drive modules 4 to transmit or separate from the core tube 5. A plane bearing 51 is provided on the outside of one end of the core tube 5. A guide channel 52 is provided on the top outer wall of the core tube 5. A gear ring 53 is provided on the outer wall of one end of the core tube 5 and is transmitted and connected to the drive module 4. The gear ring 53 meshes with the large gear 44 or the small gear 42 to realize the transmission of motion.

[0028] In this embodiment, a planar bearing 51 is also provided on one side of the end cap 11. The planar bearing 51 is used to support the core tube 5 at the end cap 11 and the lens 6, reduce friction, and allow the core tube 5 to rotate more freely outside the sleeve 13.

[0029] Please see Figure 3 and Figure 5 A shifting mechanism 3 is fixedly installed on one end of the base bushing 1. The shifting mechanism 3 includes a motor base 31 fixed on the outer wall of the base bushing 1, and a forward and reverse motor 32 is connected to the outer wall of the motor base 31. A swing arm 33 is connected to the output shaft of the forward and reverse motor 32, and a collar 34 is fixedly installed at both ends of the swing arm 33.

[0030] In this embodiment, the position of the two drive modules 4 can be changed by the switching mechanism 3, so that one of the two drive modules 4 is connected to the core tube 5 for transmission, thereby driving the core tube 5 to rotate at different efficiencies, and adjusting the position of the zoom lens 7 at different efficiencies.

[0031] Please see Figure 3 and Figure 5 Both ends of the switching mechanism 3 are provided with drive modules 4. One of the two drive modules 4 is connected to the core tube 5 for transmission. The drive module 4 includes a servo motor 1 41 and a servo motor 2 43 set inside the collars 34 at both ends of the swing arm 33. A small gear 42 is connected to the output shaft of the servo motor 1 41, and a large gear 44 is connected to the output shaft of the servo motor 2 43.

[0032] In this embodiment, taking the rotation of the gear ring 53 driven by the pinion 42 as an example, the servo motor 41 moves towards the gear ring 53 of the core tube 5. The pinion 42 meshes with the gear ring 53, thereby driving the core tube 5 to rotate. When the large gear 44 drives the gear ring 53, the switching mechanism 3 needs to be activated to achieve the position switching of the two drive modules 4.

[0033] In the above scheme, it should be noted that when the shifting mechanism 3 drives the pinion 42 to mesh with the gear ring 53, the gear 44 will separate from the gear ring 53. Similarly, when the shifting mechanism 3 drives the gear 44 to mesh with the gear ring 53, the pinion 42 will separate from the gear ring 53. At the same time, both the pinion 42 and the gear 44 can maintain stable meshing contact with the gear ring 53.

[0034] Please see Figure 1 and Figure 2 The outer casing 2 is fitted around the base bushing 1 and the core tube 5. A lug 21 is provided on one side of the outer wall of the outer casing 2. The lug 21 is fitted around the outside of the switching mechanism 3.

[0035] In this embodiment, the outer shell 2 is used to protect the internal core tube 5 and the zoom lens 7. The lug 21 is a protruding structure of the outer shell 2 to adapt to the installation space of the switching mechanism 3 and play a protective role. In specific assembly, the core tube 5 is sleeved on the outside of the base bushing 1, and then the outer shell 2 is sleeved on the outside of the core tube 5. At this time, one end of the outer shell 2 is in contact with the end cap 11. Finally, the lens 6 is fixed to the end of the base bushing 1 to realize the compression and limiting of one end of the outer shell 2.

[0036] Please see Figure 4 A zoom lens 7 is slidably installed inside the base bushing 1. The drive module 4 drives the core tube 5 to rotate, and the core tube 5 drives the zoom lens 7 to slide linearly inside the base bushing 1. A follower block 71 is fixedly installed on the top of the zoom lens 7, and sliders 72 are provided on both sides of the zoom lens 7.

[0037] In this embodiment, the follower block 71 can move simultaneously inside the guide channel 16 and the guide channel 52, so as to realize the linear movement of the zoom lens 7 inside the sleeve 13, thereby changing the distance between the zoom lens 7 and the lens 6 and achieving the purpose of zoom adjustment. The slider 72 slides inside the slide groove 14, which plays a guiding role in the movement of the zoom lens 7.

[0038] The working principle and usage process of this utility model are as follows: First, the base bushing 1 is connected to the shooting equipment of the drone, and then the lens 6 is installed at the end of the base bushing 1.

[0039] When using a drone for shooting, the switching mechanism 3 can be activated to select one of its drive modules 4 to drive the core tube 5. If the drive module 4 of the servo motor 41 is selected to drive the core tube 5, the switching mechanism 3 is activated, and the forward and reverse motor 32 is activated to drive the swing arm 33 to rotate. The swing arm 33 drives the collar 34 to move, so that the servo motor 41 moves towards the gear ring 53 of the core tube 5. The pinion 42 meshes with the gear ring 53, thereby using the servo motor 41 to drive the core tube 5 to rotate. When the core tube 5 rotates, due to the guide channel 2 52 set on its surface, the follower block 71 on the zoom lens 7 can move inside the guide channel 2 52. At the same time, under the limiting action of the guide channel 16, that is, under the combined action of the guide channel 16 and the guide channel 2 52, the follower block 71 can move linearly along the inside of the sleeve 13 to change the position of the zoom lens 7 inside the sleeve 13, change the distance between the zoom lens 7 and the lens 6, and achieve the zoom adjustment effect.

[0040] It should be noted that when servo motor 1 41 and servo motor 2 43 rotate at the same speed, the speed at which the pinion 42 drives the gear ring 53 to rotate is less than the speed at which the gear 44 drives the gear ring 53 to rotate, thereby achieving rotational motion of the gear ring 53 with different efficiencies, and achieving zoom adjustment of the zoom lens 7 with different efficiencies.

[0041] In the above scheme, it should also be noted that: the forward and reverse motor 32, servo motor 1 41 and servo motor 2 43 in this application are all connected to the power supply and controller of the UAV using existing wire connection methods. In this way, the operating status of the forward and reverse motor 32, servo motor 1 41 and servo motor 2 43 can be controlled by the UAV remote controller. At the same time, since the remote control technology of UAV is a common technical means in the field of UAV technology, and the improvement and innovation of this application is not in the UAV control program, the control of the forward and reverse motor 32, servo motor 1 41 and servo motor 2 43 adopts the existing UAV control technology, which will not be described in detail here.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
