It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The technical scheme disclosed by each embodiment of the application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the present application discloses a camera, which includes a main body assembly 100, a light supplementing assembly 200, and a first driving mechanism 300.

The main body assembly 100 includes a lens module 110 and a transparent cover 120, the transparent cover 120 has a receiving cavity, the lens module 110 is disposed in the receiving cavity, and the lens module 110 is used for shooting through the transparent cover 120. The light filling assembly 200 is disposed on the main body assembly 100 and is located outside the light-transmitting cover 120. The light supplementing assembly 200 is used for supplementing light when the lens module 110 shoots, the light supplementing assembly 200 is located outside the light transmitting cover 120, and the light supplementing assembly 200 can emit infrared light or other light. The accommodating cavity formed by the light-transmitting cover body 120 is used for accommodating components such as the lens module 110, and the light supplementing component 200 is located outside the light-transmitting cover body 120, so that the light-transmitting cover body 120 is used for separating the light supplementing component 200 from components (such as the lens module 110) in the accommodating cavity, and the arrangement of the cavities is realized. In this case, the light emitted by the light supplementing component 200 does not need to pass through the light-transmitting cover 120, and the light supplementing light cannot be introduced into the lens module 110 through the transmission of the light-transmitting cover 120, so that the influence on the shooting of the lens module 110 can be avoided.

The lens module 110, the light supplementing assembly 200 and the first driving mechanism 300 may be directly connected or indirectly connected. The movement of the lens module 110 and the light supplementing assembly 200 may be a rotational movement about a specific axis or may be other movement. For example, after the camera is mounted and fixed, the lens module 110 and the light supplementing assembly 200 may be rotationally moved about an axis perpendicular to a horizontal plane to achieve rotational photographing in a horizontal direction. The light supplementing range is a range that light emitted by the light supplementing component 200 can irradiate, and the view field range is a shooting range that the lens module 110 can shoot. The light filling range covers the field of view, specifically, the shooting areas shot by the lens module 110 are all located in the irradiation range of the light filling component 200. The lens module 110 and the light compensating assembly 200 may move synchronously, and of course, when the light compensating range is relatively large, the lens module 110 may move first, the light compensating assembly 200 may move later, or the light compensating assembly 200 may move first, and the lens module 110 may move later, so long as the light compensating range always covers the field range.

The main body assembly 100 comprises a lens module 110 and a light-transmitting cover body 120, wherein the light-transmitting cover body 120 is provided with a containing cavity, so that the lens module 110 can be arranged in the containing cavity; through setting up first actuating mechanism 300, first actuating mechanism 300 locates main body assembly 100, make camera lens module 110 and light filling subassembly 200 all can be connected with first actuating mechanism 300, and then make first actuating mechanism 300 can drive camera lens module 110 motion, make camera lens module 110 can move other positions or angles and shoot, in order to enlarge camera's shooting range, first actuating mechanism 300 can drive light filling subassembly 200 motion, with the light filling position of changing light filling subassembly 200, so that the light filling scope of light filling subassembly 200 covers the visual field scope of camera lens module 110 all the time, thereby can solve the problem that the light filling scope of light filling subassembly can not cover the visual field scope when the visual field scope takes place to change because of the motion of camera lens module, thereby the shooting performance of camera has been improved effectively, and locate light filling subassembly 200 outside the printing opacity cover 120, make light filling subassembly 200 separate through the printing opacity cover 120 with camera lens module 110, thereby can solve the problem that light leakage to the camera of camera is influenced by light that light filling subassembly 200 is sent out because when light filling subassembly 200 and camera lens module 110 all install the condition in the camera inner chamber.

In the case where the light compensating assembly 200 is one, the light compensating assembly 200 can be located only at one side of the light-transmitting cover 120, and thus, the light compensating range of the light compensating assembly 200 is limited. In order to further improve the light supplementing capability, preferably, the light supplementing components 200 may be two, the light-transmitting cover 120 may include two mounting portions 122 disposed opposite to each other, the light-transmitting portion 121 is disposed between the two mounting portions 122, the light-transmitting portion 121 is connected with the two mounting portions 122 to enclose a containing cavity, and the two light supplementing components 200 may be respectively mounted on the two mounting portions 122.

In some cases, in order to meet the requirements of explosion protection, the light-transmitting cover 120 is designed such that only the portion of the light-transmitting cover 120 opposite to the lens module 110 can transmit light, and other portions are made of explosion-proof materials. Therefore, the field of view of the lens module 110 cannot be rotated to the light-opaque region of the light-transmitting cover 120, thus resulting in a limited photographing range of the camera. In order to improve the shooting range of the camera, optionally, the first driving mechanism 300 may be connected to the transparent cover 120, where the first driving mechanism 300 may drive the transparent cover 120 and the lens module 110 to move together, and the relative position of the lens module 110 and the transparent cover 120 remains unchanged, that is, the relative position of the lens module 110 and the transparent area of the transparent cover 120 remains unchanged all the time during the movement process.

Specifically, the connection between the first driving mechanism 300 and the light-transmitting cover 120 may be a direct connection or an indirect connection, for example, the first driving mechanism 300 is connected to the lens module 110, and the lens module 110 is connected to the light-transmitting cover 120.

For example, the lens module 110 and the light-transmitting cover 120 rotate together in 360 degrees in the horizontal direction.

The first driving mechanism 300 drives the light-transmitting cover 120 and the lens module 110 to move together, so that the relative positions of the lens module 110 and the light-transmitting cover 120 are kept unchanged, and the relative positions of the lens module 110 and the light-transmitting cover 120 are kept unchanged regardless of movement of the lens module 110, thereby effectively avoiding the movement of the lens module 110 to an opaque region of the light-transmitting cover 120, and effectively improving the shooting range of the camera.

In order to move the lens module 110 together with the transparent cover 120 so that the positions of the lens module 110 and the transparent cover 120 are fixed, the main body assembly 100 may further include an outer cover 150 and a bracket assembly 160 according to the structure of the camera, the outer cover 150 may be connected with the transparent cover 120 to enclose a camera cavity, the bracket assembly 160 may be located in the camera cavity, the bracket assembly 160 may be connected with the outer cover 150, the lens module 110 may be disposed on the bracket assembly 160, and the accommodating cavity forms at least part of the camera cavity. The first driving mechanism 300 may be connected to the bracket assembly 160, and the first driving mechanism 300 may drive the bracket assembly 160 to move, so that the bracket assembly 160 drives the lens module 110, the housing 150 and the transparent cover 120 to move together. The bracket assembly 160, the lens module 110, the housing 150 and the light-transmitting cover 120 form an integral structure, and when the first driving mechanism 300 drives the bracket assembly 160 to move, the integral structure moves together.

Through setting up support subassembly 160 for first actuating mechanism 300 can be through support subassembly 160 and camera lens module 110, the indirect connection of printing opacity cover body 120, and then makes first actuating mechanism 300 can drive support subassembly 160 motion, so that support subassembly 160 drives camera lens module 110, dustcoat 150 and printing opacity cover body 120 and moves together, thereby makes and connects camera lens module 110, dustcoat 150 and printing opacity cover body 120 as a whole through support subassembly 160, makes the relative position of camera lens module 110 and printing opacity cover body 120 more stable.
