Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a protective video recording device for UAVs. Background Technology

[0002] With the rapid development of drone technology, its application areas are constantly expanding, playing an important role in aerial photography, surveying, inspection, emergency rescue and other work. As a key component for drones to acquire information, the normal operation of the video recording device is crucial.

[0003] Existing drone camera technology for image recognition has the following problems: drone cameras are generally fixed to the bottom of the drone by clips or nuts. Clips are very easy to fix and remove but not very secure, while nuts are very secure but are more troublesome to install and remove.

[0004] An existing patent (publication number: CN212951167U) discloses a drone camera for image recognition. By changing the part of the drone camera that is fixed to the drone to a convenient fixing device, the connection between the camera and the drone becomes both secure and easy to install and remove. Through a movable sleeve, the connecting plate at the bottom of the drone is fixed inside the connection port. This is much more secure than the snap-on fastening of a typical drone camera at the bottom of the drone, and much easier to install and remove than a camera connected by a nut. This makes the use of this new drone camera for image recognition more user-friendly.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in most existing drones, the recording lens is directly connected to the front of the recording lens via a protective lens. When the protective lens is accidentally scratched by tree branches or struck by beetles, it lacks a buffering function, which can easily cause the protective lens to shatter. This can result in irreversible scratches from the broken protective lens on the recording lens, and severe impacts can easily damage the recording lens gimbal.

[0006] Therefore, a protective video recording device based on unmanned aerial vehicles (UAVs) is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a protective recording device for drones, which can solve the problem that most existing drone recording lenses are directly connected to the front of the recording lens through a protective lens. When the protective lens is accidentally scratched by tree branches or hit by beetles, it does not have a buffer function, which can easily cause the protective lens to break. This can cause irreversible scratches to the recording lens from the broken protective lens, and in severe impacts, it can easily damage the gimbal of the recording lens.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective recording device for drones, comprising a drone lens body and a drone gimbal body, wherein a buffer mechanism is provided on the surface of the drone lens body and a protective mechanism is provided on the surface of the drone lens body.

[0009] The buffer mechanism includes a support ring, an airbag, and a sliding ring. The support ring is fixedly sleeved on the surface of the drone lens body, the airbag is movably sleeved on the surface of the drone lens body, the rear side of the airbag contacts the front side of the support ring, and the sliding ring is slidably sleeved on the surface of the drone lens body, the rear side of the sliding ring contacts the front side of the airbag.

[0010] Preferably, the airbag is made of neoprene rubber and is filled with nitrogen.

[0011] Preferably, the inner wall of the sliding ring is provided with a sliding groove, and the number of sliding grooves is four and they are evenly distributed on the inner wall of the sliding ring. A limiting block that cooperates with the sliding groove is fixedly connected to the surface of the drone lens body, and the surface of the limiting block is in active contact with the inside of the sliding groove.

[0012] Preferably, a limiting ring is fixedly fitted on the surface of the drone lens body, and the rear side of the limiting ring contacts the front side of the sliding ring.

[0013] Preferably, the protective mechanism includes a plurality of rubber strips, a protective sleeve, and a protective goggle. The protective goggle is fixedly connected to the inner wall of the protective sleeve, the rubber strips are fixedly connected to the surface of the protective sleeve, and the inner wall of the protective sleeve is threadedly connected to the surface of the sliding ring.

[0014] Preferably, a sealing ring is fixedly connected to the surface of the sliding ring, and the rear side of the protective sleeve is in close contact with the front side of the sealing ring.

[0015] Preferably, the protective sleeve and the sliding ring are both made of magnesium alloy, and the protective goggles are made of fluorite glass.

[0016] Preferably, the surface of the protective mirror is coated with an anti-fouling film using ion beam assisted deposition technology.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a buffer mechanism, the protective sleeve is connected to the sliding ring. When the protective lens is impacted, the airbag can buffer the impact force, reduce the risk of the protective lens breaking and the risk of damage to the drone gimbal body, thereby improving the protection performance of the drone lens body and the drone gimbal body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A protective recording device for drones includes a drone lens body 1 and a drone gimbal body 9. A buffer mechanism 2 is provided on the surface of the drone lens body 1, and a protective mechanism 3 is provided on the surface of the drone lens body 1.

[0030] The buffer mechanism 2 includes a support ring 201, an airbag 202, and a sliding ring 203. The support ring 201 is fixedly sleeved on the surface of the drone lens body 1, the airbag 202 is movably sleeved on the surface of the drone lens body 1, the rear side of the airbag 202 contacts the front side of the support ring 201, and the sliding ring 203 is slidably sleeved on the surface of the drone lens body 1, the rear side of the sliding ring 203 contacts the front side of the airbag 202.

[0031] In this embodiment: the support ring 201 is fixed to the surface of the drone lens body 1 to provide rear support for the airbag 202. The limiting ring 5 restricts the forward sliding of the sliding ring 203. The sliding ring 203 cooperates with the limiting block 4 through the sliding groove 7 and can slide back and forth along the drone lens body 1. The protective sleeve 302 is threadedly connected to the sliding ring 203. The protective lens 303 is fixed to its inner wall. The sealing ring 6 ensures the seal. When the drone is flying, if the protective lens 303 is scratched by a tree branch or hit by a flying insect, the impact force is transmitted to the protective sleeve 302 and the protective lens 303. Because the protective sleeve 302 is threadedly connected to the sliding ring 203, the sliding ring 203 moves backward. The compression airbag 202, made of neoprene and filled with nitrogen, absorbs and disperses impact force through its elasticity and the cushioning properties of nitrogen, reducing the risk of the protective lens 303 breaking and minimizing damage to the drone gimbal 9. This solves the problem that in most existing drones, the recording lens is directly connected to the front of the recording lens through the protective lens. When the protective lens is accidentally scratched by tree branches or hit by beetles, it lacks a cushioning function, which can easily lead to the protective lens breaking. This can cause irreversible scratches to the recording lens from the broken protective lens, and in severe impacts, it can easily damage the recording lens gimbal.

[0032] Specifically, such as Figure 3 As shown, the airbag 202 is made of neoprene rubber and is filled with nitrogen.

[0033] Specifically, such as Figure 3 and Figure 4 As shown, the inner wall of the sliding ring 203 is provided with a groove 7. There are four grooves 7, which are evenly distributed on the inner wall of the sliding ring 203. The surface of the drone lens body 1 is fixedly connected with a limiting block 4 that works with the groove 7. The surface of the limiting block 4 is in contact with the inside of the groove 7.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a limiting ring 5 is fixedly fitted on the surface of the drone lens body 1, and the rear side of the limiting ring 5 contacts the front side of the sliding ring 203.

[0035] In this embodiment: the neoprene rubber airbag 202 filled with nitrogen has good elasticity and flexibility, as well as the interaction force between nitrogen molecules. The airbag 202 can effectively absorb the impact force and disperse and buffer it. By sliding the limiting block 4 inside the slide groove 7, the sliding ring 203 can only move back and forth on the surface of the drone lens body 1, preventing the sliding ring 203 from rotating. This makes it convenient to connect the protective sleeve 302 and the sliding ring 203 by thread. The limiting ring 5 can restrict the sliding ring 203 from moving forward and prevent the sliding ring 203 from detaching from the drone lens body 1.

[0036] Specifically, such as Figure 5 As shown, the protective mechanism 3 includes several rubber strips 301, a protective sleeve 302, and a protective goggle 303. The protective goggle 303 is fixedly connected to the inner wall of the protective sleeve 302, the rubber strips 301 are fixedly connected to the surface of the protective sleeve 302, and the inner wall of the protective sleeve 302 is threadedly connected to the surface of the sliding ring 203.

[0037] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a sealing ring 6 is fixedly connected to the surface of the sliding ring 203, and the rear side of the protective sleeve 302 is in close contact with the front side of the sealing ring 6.

[0038] In this embodiment: by holding the rubber strip 301, the protective sleeve 302 can be easily rotated, making it easy to connect the protective sleeve 302 and the sliding ring 203 by thread. The sealing ring 6 ensures the sealing of the connection between the protective sleeve 302 and the sliding ring 203, preventing dust and moisture from entering.

[0039] Specifically, such as Figure 4 and Figure 5 As shown, the protective sleeve 302 and the sliding ring 203 are both made of magnesium alloy, and the protective goggles 303 are made of fluorite glass.

[0040] Specifically, such as Figure 6 As shown, the surface of the protective goggle 303 is coated with an anti-fouling film 8 by ion beam assisted deposition technology.

[0041] In this embodiment: the protective sleeve 302 and the sliding ring 203 are made of magnesium alloy, which is lightweight, corrosion-resistant and has good dimensional stability, which can reduce the load on the drone. The protective lens 303 has an anti-fouling coating 8 formed by ion beam assisted deposition technology, which can prevent dust and stains from adhering and maintain good light transmittance.

[0042] Working principle: The support ring 201 is fixedly sleeved on the surface of the drone lens body 1 to provide rear support for the airbag 202. The limiting ring 5 is also fixedly sleeved on the drone lens body 1 to restrict the forward sliding of the sliding ring 203. The sliding groove 7 on the inner wall of the sliding ring 203 cooperates with the limiting block 4 on the surface of the drone lens body 1, so that the sliding ring 203 can only slide back and forth along the surface of the drone lens body 1. The protective sleeve 302 is connected to the sliding ring 203 by threads. The protective lens 303 is fixed to the inner wall of the protective sleeve 302. The sealing ring 6 ensures the sealing of the connection between the protective sleeve 302 and the sliding ring 203. To prevent dust and moisture from entering, when the drone is in flight and the protective goggle 303 is accidentally scratched by a tree branch or struck by a beetle, the impact force is first applied to the protective cover 302 and the protective goggle 303. Since the protective cover 302 is connected to the sliding ring 203 by threads, the sliding ring 203 can slide along the drone's lens body 1. Upon impact, the sliding ring 203 will push backward against the airbag 202. The airbag 202 is made of neoprene rubber and filled with nitrogen. Thanks to the good elasticity and flexibility of neoprene rubber, and the intermolecular forces of nitrogen, the airbag 202 can effectively absorb the impact force. By dispersing and buffering the impact, not only is the direct impact force on the protective goggle 303 reduced, decreasing the risk of breakage, but the impact force transmitted to the drone gimbal body 9 is also reduced through buffering, preventing damage to the drone gimbal body 9 due to excessive impact. The surface of the protective goggle 303 is coated with an anti-fouling film 8 formed by ion beam assisted deposition technology, which prevents dust and stains from adhering and maintains good light transmittance. At the same time, the protective sleeve 302 and the sliding ring 203 are made of magnesium alloy, which is lightweight, corrosion-resistant, and has good dimensional stability, reducing the load on the drone. The protective goggle 303 is made of fluorite glass and has... It has extremely low chromatic dispersion, which ensures clear shooting images and provides good protection for drone video recording. It solves the problem that most existing drone video lenses are directly connected to the front of the video lens through a protective lens. When the protective lens is accidentally scratched by tree branches or hit by beetles, it does not have a buffer function and is prone to breakage. This can cause irreversible scratches to the video lens from the broken protective lens, and severe impacts can easily damage the video lens gimbal. It should be noted that both the drone lens body 1 and the drone gimbal body 9 are existing and mature technologies that have been published, and will not be described in detail here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
