DETAILED DESCRIPTION

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with the embodiments.

Referring toFIG. 2toFIG. 5,FIG. 2is a schematic front view showing the structure of a combined camera provided by the present application,FIG. 3is a schematic right view showing the structure of the combined camera as shown inFIG. 2,FIG. 4is a schematic cross-sectional structural view taken along line A-A ofFIG. 2, andFIG. 5is a schematic cross-sectional structural view taken along line B-B ofFIG. 3.

Referring toFIG. 2toFIG. 5, the combined camera provided by a specific embodiment of the application includes a first camera housing10inside which a first camera11is provided. One side of the first camera housing10is provided with a rotating disc30that is rotatable relative to the first camera housing10. A rotating bracket is fixed on the rotating disc30, a second camera housing20that is rotatable relative to the rotating bracket is provided on the rotating bracket, and a second camera21is provided within the second camera housing20.

It should be noted that, in this embodiment, the rotation axes of the rotating disc30and the second camera housing20are perpendicular to each other in different planes, and are distinguished here by horizontal and vertical. That is, the rotating disc30rotates in a horizontal plane with respect to the first camera housing10, and the second camera housing20rotates in a vertical plane with respect to the rotating bracket.

Of course, the rotation axes of both the rotating disc30and the second camera housing20may intersect, as long as monitoring requirements on the combined camera can be satisfied. The specific angle is set by those skilled in the art according to the actual structure.

In detail, the first camera housing10has a concave rotating disc insertion hole10a. The rotating disc30is completely inserted into the rotating disc insertion hole10aand directly connected to the first camera housing10through a bearing. The first drive mechanism drives the rotating disc30to rotate in a horizontal plane relative to the first camera housing10.

Preferably, in the specific embodiment, the first drive mechanism comprises a first motor12and a first synchronous belt transmission mechanism. Wherein, the first motor12is fixedly mounted within the first camera housing10, and the first synchronous belt transmission mechanism includes a first driving synchronous pulley13, a first driven synchronous pulley14, and a first synchronous belt15. The first driven synchronous pulley14is coaxially and fixedly connected to the rotating disc30. The first driving synchronous pulley13is coaxially and fixedly connected to the electrical pivot of the first motor12, and the first synchronous belt15is engaged with the first driving synchronous pulley13and the first driven synchronous pulley14to tension the internal teeth.

That is, the first motor12drives the rotating disc30to rotate in a horizontal plane with respect to the first camera housing10by the first synchronous belt transmission mechanism. The rotating disc30is fixedly connected to the rotating bracket, to which the second camera housing20is directly rotatably connected, and the second camera21is fixed to the second camera housing20. Therefore, the rotation of the rotating disc30relative to the first camera housing10in the horizontal plane can drive the second camera21to rotate simultaneously to adjust the monitoring angle of the second camera21in the horizontal plane.

With continued reference toFIG. 4andFIG. 5, there are two rotating brackets, which are respectively provided on two sides of the second camera21. In order to facilitate the understanding of the specific structure of such a camera by those skilled in the art, the two rotating brackets are distinguished here by orientation words. The orientation words, left and right, are defined on the basis of the second camera housing21inFIG. 4. That is to say, of the two rotating brackets, the left rotating bracket40is located on the left side of the second camera housing21, and the right rotating bracket41is located on the right side of the second camera housing21. The second camera housing20is rotatably connected to the left rotating bracket40and right rotating bracket41by bearings.

In detail, the left rotating bracket40has a bracket bearing hole, and the right rotating bracket has a bracket rotating shaft. The second camera housing20has a second camera housing bearing hole and a second camera housing rotating shaft. The bracket bearing hole, the bracket rotating shaft, the second camera housing bearing hole and the second camera housing rotating shaft are concentrically arranged. The left rotating bracket40and the second camera housing20are rotatably connected by a bearing mounted between the bracket bearing hole and the second camera housing rotating shaft. The right rotating bracket41and the second camera housing20are rotatably connected by a bearing mounted between the second camera housing bearing hole and the bracket rotating shaft. The second drive mechanism drives the second camera housing20to rotate in a horizontal plane with respect to the left and right rotating brackets40,41.

Similarly, in the specific embodiment, the second drive mechanism comprises a second motor22and a second synchronous belt transmission mechanism. Wherein, the second motor22is fixedly mounted within the second camera housing20, and the second synchronous belt transmission mechanism includes a second driving synchronous pulley (not shown in the figures), a second driven synchronous pulley24, and a second synchronous belt25. The second driven synchronous pulley24is coaxially and fixedly connected to the bracket rotating shaft. The second driving synchronous pulley is coaxially and fixedly connected to the electrical pivot of the second motor22. The second synchronous belt25is engaged with the second driving synchronous pulley and the second driven synchronous pulley24to tension the internal teeth.

That is, the second motor22drives the second camera housing20to rotate in a vertical plane by the second synchronous belt transmission mechanism. Moreover, the second camera21is fixed to the second camera housing20. Therefore, the rotation of the rotating disc30relative to the first camera housing10in the vertical plane can drive the second camera21to rotate to adjust the monitoring angle of the second camera21in the vertical plane.

Obviously, the second camera housing20of the combined camera is directly rotatably connected to the first camera housing10through both the rotating disc30and the rotating bracket, thereby eliminating the mounting bracket and the base in the existing combined camera of a gun-ball linkage structure, thus simplifying the overall structure and reducing its height dimension in the vertical direction.

In addition, compared to the prior art, the first motor12and the second motor22are respectively provided within the first camera housing10and the second camera housing20, so that the overall structure is simplified to a certain extent and the vertical dimension is reduced. Moreover, synchronous belt transmission mechanisms are used as the first transmission mechanism and the second transmission mechanism, so that the combined camera has a compact overall structure and a stable transmission. Of course, the second transmission mechanism and the first transmission mechanism may also be a gear transmission mechanism, a sprocket transmission mechanism, or the like, as long as the requirements of the deceleration function and the assembly process are satisfied.

Further, with continued reference toFIG. 4andFIG. 5, the main board60of the combined camera is integrated with a power supply module, a core switching module, and a pan/tilt head module. Wherein, the power supply module is used to supply power to the first camera11, the second camera21, the first motor12, and the second motor22. The pan/tilt head module is used to control the first motor12and the second motor22, and the core switching module is used for signal switching between the first camera11, the second camera21and a console (specifically including network, BNC, 485, uart, etc.).

In addition, the combined camera further includes a connecting wire50, which is electrically connected to the main board60at one end, and is extended, at the other end, through the first camera housing10, the rotating disc30and into the second camera housing20, and electrically connected to the second camera21and the second motor22.

It is conceivable that compared to the combined camera combined with the first camera and the second camera in the prior art, the combined camera in this embodiment adopts a main board60, which is integrated with a plurality of functional modules and supplies and controls both the first camera11and the second camera21, greatly simplifying the structure thereof.

Preferably, with continued reference toFIG. 4andFIG. 5, the first camera housing10is a cylindrical housing. The first camera11, the rotating disc30and the first motor12are sequentially arranged along the length direction of the first camera housing10, and the main board60is arranged along the length direction of the first camera housing10.

In this way, the structure of the combined camera is compact and reasonable, which can further define the height dimension of the combined camera in the vertical direction.

In addition, in the embodiment, there are three first cameras11, which are sequentially distributed along an arc to acquire a first image of a monitoring area. It can be understood that the setting of the number of the first cameras11as three is illustrative only, and a person skilled in the art can determine an appropriate number of first cameras11according to actual monitoring requirements. That is, any number of the first cameras11are included within the protection scope of the present application.

Furthermore, as can be seen in conjunction withFIGS. 4 and 5, the first camera housing10and the second camera housing20are both waterproof sealing housings, such that the functional components such as the first camera11, the second camera21and the main board60are sealingly mounted, so that the combined camera has a certain waterproof function, and then the scope of application thereof is expanded.

In detail, the first camera housing10has a first waterproof sealing cavity1a, a first image collecting hole and a first transparent cover103. The first camera11, the main board60and the first motor12are all located within the first waterproof sealing cavity1a. The first image collecting hole is communicated with the first waterproof sealing cavity1aand is blocked by the first transparent cover103, enabling the first camera11to collect an image of an external object through the first transparent cover103.

In more detail, the first camera housing10includes a first bottom shell101and a first shell cover102. Wherein, the first bottom shell101and the first shell cover102are sealingly connected to form the first waterproof sealing cavity1a. The first camera11is fixed within the first waterproof sealing cavity1a, and the first image collecting hole is opened in the first bottom shell101or the first shell cover102.

Similarly, the second camera housing20has a second waterproof sealing cavity2a, a second image collecting hole and a second transparent cover203. Wherein, the second camera21and the second motor22are both located within the second waterproof sealing cavity2a. The second image collecting hole is communicated with the second waterproof sealing cavity2aand is blocked by the second transparent cover203, enabling the second camera21to collect an image of an external object through the second transparent cover203.

More specifically, the second camera housing20includes a second bottom shell201and a second shell cover202. Wherein, the second bottom shell201and the second shell cover202are sealingly connected to form the second waterproof sealing cavity2a, and the second image collecting hole is opened in the second bottom shell201or the second shell cover202.

With continued reference toFIG. 2andFIG. 3, in the present embodiment, the first camera housing10is gun-shaped, and the second camera housing20is spherical.

The above description is only the preferred embodiments of the present application, and is not intended to limit the present application. Various changes and modifications may be made by a person skilled in the art in the present application. Any amendments, equivalent substitutions, improvements etc. made within the spirit and principle of the present application are all included in the protection scope of the present application.
