Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and features in the embodiments may be combined with each other without conflict.

The photographing equipment of the present application belongs to the technology of photographing equipment and is used for photographing pictures and/or videos. The photographing equipment can be hand-held by the photographer or used in conjunction with a PTZ, or can be combined with the PTZ to form a shooting component and be mounted on a carrier, wherein, The carrier can be any fixed object or movable object, for example, farmland, forest, building, vehicle, human body, animal body, etc. In this embodiment, the carrier is an unmanned aerial vehicle, and the photographing device and the pan/tilt constitute a photographing component mounted on the camera. Aerial photography operations can be carried out on unmanned aerial vehicles.

When the unmanned aerial vehicle is shooting in a high temperature and high humidity environment, the transparent lens at the front end of the lens barrel is prone to fogging, which affects the shooting quality of the shooting equipment. Therefore, in the present application, the lens barrel is sealed in the sealed cavity enclosed by the lens seat, the transparent lens and the hollow structure, so as to solve the above problems and improve the shooting quality of the shooting equipment of the drone in the high temperature and high humidity environment .

As shown in FIGS. 1 to 3 , the photographing device 100 according to the embodiment of the present application includes a housing module 10 and a camera module 20, wherein the camera module 20 includes a lens holder 22 and at least one lens barrel mounted on the lens holder twenty one. The casing module 10 includes a transparent lens 12 and a casing 11. The casing 11 has a hollow structure body 111 with openings at both ends. Inside the body 111 , and the direction of the lens barrel faces the transparent lens 12 . A sealing assembly 30 is connected between the lens holder 22 and the hollow structure 111 , and the sealing assembly 30 is composed of a sealing ring 31 and a sealing pressing sheet 32 . The sealing assembly 30 is used to seal the lens barrel 21 on the lens holder 22 and the transparent lens 12 . and the hollow structure body 111 in the sealed cavity enclosed by the three.

Since the present application uses the sealing assembly 30 to seal the lens barrel 21 in the sealed cavity enclosed by the lens base 22 , the transparent lens 12 and the hollow structure 111 , when the photographing device 100 is located in a high temperature and high humidity environment, the external environment The water vapor will not enter the sealed cavity, thereby avoiding the problem that the transparent lens 12 at the front end of the lens barrel 21 close to one end face of the lens barrel 21 is prone to fogging. In addition, since the sealing assembly 30 is composed of the sealing ring 31 and the sealing pressing sheet 32, the sealing ring 31 is installed in the hollow structure 111 through the sealing pressing sheet 32, which solves the problem that the traditional sealing ring 31 cannot be pressed due to space reasons, and at the same time The sealing effect in the sealing cavity is also improved, and the assembly of the sealing ring 31 is facilitated.

It can be understood that when the traditional photographing device 100 is used in different working environments, such as high altitude, deep sea, rainy days or cold regions, when the lens holder 22 , the transparent lens 12 and the hollow structure 111 are enclosed by the seal When the cavity is not sufficiently sealed, external water molecules can easily enter the sealed cavity through the gap, wherein the photographing device 100 generally has the characteristics of small size and high heat generation. Therefore, when the internal temperature of the photographing device 100 is higher than the outside temperature, the water molecules inside the photographing device 100 liquefy when encountering the low-temperature transparent lens 12 , and condense into fog-like water droplets on the surface of the transparent lens 12 close to the interior of the photographing device 100 . When the light enters the camera module 20 from the outside, the water droplets cause the light to undergo changes such as refraction and reflection, which affects the shooting effect. In the present application, the transparent lens 12 is packaged on the opening at one end of the hollow structure 111 , and the lens holder 22 is connected to the other end of the hollow structure 111 through the sealing assembly 30 , so that the lens barrel 21 can be sealed on the lens holder 22 and the transparent lens 12 and the hollow structure body 111 in the sealed cavity, so as to completely solve the problem of water vapor in the external environment entering the sealed cavity, and prevent the front end of the lens barrel 21 from fogging easily on the transparent lens 12 near one end of the lens barrel 21 The problem.

In an optional embodiment, as shown in FIGS. 3 to 10 , the hollow structural body 111 is provided with a fixing portion 112 and a mounting portion 115 having a first preset distance from the fixing portion 112 , wherein the transparent lens 12 is bonded to the fixing portion 112 by an adhesive, and the sealing assembly 30 is arranged between the mounting portion 115 and the lens holder 22 .

Wherein, the first preset distance can be any length, and its purpose is mainly to enable the lens barrel 21 to be located inside the transparent lens 12 and to have a preset gap with the transparent lens 12, and to ensure that the lens seat 22 can seal the sealing assembly 30 at the same time. Pressed on the mounting part 115, the lens barrel 21 can be completely sealed in the sealed cavity enclosed by the lens holder 22, the transparent lens 12 and the hollow structure 111, so as to prevent the photographing device 100 from being in a high temperature and high humidity environment. Water vapor in the external environment will not enter the sealed cavity, causing the problem that the transparent lens 12 at the front end of the lens barrel 21 close to one end face of the lens barrel 21 is prone to fogging.

In this embodiment, the first preset distance refers to the farthest distance between the fixing portion 112 and the mounting seat 1151 , and the second preset distance refers to the farthest distance between the ring edge 1152 and the mounting seat 1151 , wherein the first preset distance The distance is greater than the length of the lens barrel 21 , and the second preset distance is less than the thickness of the sealing ring 31 . In this embodiment, the flange 221 is provided with a pressing groove 2211, and the depth of the pressing groove 2211 matches the thickness of the sealing pressing sheet 32, that is, when the sealing ring 31 is put into the hollow structure 111, the After one end face is in contact with the end face of the ring edge 1152 , the sealing pressing piece 32 is put into the hollow structure 111 for fixing the sealing ring 31 .
