The utility model relates to a camera device, in particular to an automatic rotating spherical camera device.

At present, the commonly used camera-carrying device in building elevators or general stores is to mount the camera on a gyrator driven by a motor, and scan left and right at a certain speed to increase the monitoring range.

However, the above-mentioned moving camera scans back and forth in a fixed path and takes too long, which may easily cause blind spots in monitoring, so it still cannot achieve an effective monitoring function. For a relatively open place, it is necessary to use a considerable number of mobile cameras to eliminate the dead angle of monitoring, which will cause a considerable burden on the cost, and will destroy the visual beauty of the storefronts that are more particular about decoration. .

FIG. 2 is an exploded perspective view of the device shown in FIG. 1 .

Fig. 3 is a schematic diagram of the vertical driving device of the device shown in Fig. 2 .

Fig. 4 is another embodiment of the utility model.

The automatic rotating dome camera device in FIG. 1 includes a dome camera body 10 , an outer cover 20 , and a base 30 . The dome camera body 10 is accommodated in the inner space of the base 30, and is fixed on the track 32 of the base 30 by the fixing piece 34. The base 30 is provided with a track 32, and the track 32 of the base 30 is joined by the outer cover 20. The dome camera body 10 provides protection against external forces (such as collision, dust, moisture, etc.). Wherein, the outer cover 20 is made of a transparent material so as to obtain a clear image.

The detailed structure of the dome camera body is shown in FIG. 2 . The dome camera body 10 uses a turntable 16 to set up the vertical drive device 14 and the camera 12 , and a horizontal drive device 18 is connected to the bottom of the turntable 16 . A support frame 13 and a support frame 15 are arranged on the turntable 16 , and both are fixed on the turntable 16 by screws 134 and screws 154 respectively. The support frame 13 and the support frame 15 are symmetrically provided with a groove 132 and a groove 152 . The groove 132 and the groove 152 are used to fix the vertical driving device 14 . When replacing other vertical driving devices or cameras, the height of the vertical driving device fixed on the groove 132 and the groove 152 can be adjusted as required.

Wherein, the turntable 16, the support frame 13, and the support frame 15 may also be integrally formed.

The vertical driving device 14 carries the camera 12 , and its two ends are symmetrically provided with a rotating shaft 142 and a cylinder 144 , which are respectively fixed on the supporting frame 13 and the supporting frame 15 through the groove 132 and the groove 152 . Wherein, the vertical driving device 14 is preferably provided with a ball bearing shafted to the cylinder 144 so that the vertical driving device 14 can rotate stably.

The camera 12 is fixed on the vertical driving device 14, and it has a lens 122 to obtain images. The lens 122 can be fixed, zoom, or telescopic, depending on the field and individual needs.

The structure of the vertical driving device 14 is shown in Figure 3. The vertical driving device 14 includes a motor 146, a gear set 149 and a variable resistor 147. The motor 146 is preferably a DC motor. The rotating shaft of the motor 146 drives the rotating shaft 142 to rotate through the gear set 149 , and the rotating shaft 142 is pivotally connected to the variable resistor 147 . Since the rotating shaft 142 is fixed on the supporting frame 13, when the motor 146 is activated, the vertical driving device 14 rotates around the rotating shaft 142, so that the camera 12 monitors in the vertical direction. When the vertical driving device 14 rotates an angle, the resistance value of the variable resistor 147 also changes accordingly, so the vertical angular position of the camera 12 can be obtained from the resistance value of the variable resistor 147 to control the motor 146 . A bearing 148 is disposed on the other side of the vertical driving device 14 relative to the rotating shaft 142 , and the bearing 148 is pivoted to the cylinder 144 so as to be fixed on the bracket 15 .

The structure of the horizontal drive unit 18 is roughly the same as that of the vertical drive unit 14, and its rotating shaft 182 is fixed on the turntable 16 so as to drive the turntable 16 to rotate; according to the resistance value of the variable resistor inside the horizontal drive unit 18, the turntable can be obtained. 16 drives the angular position of the camera 12 in the horizontal direction so as to control the horizontal driving device 18 .

During the operation of the dome camera body 10, the horizontal driving device 18 is controlled to drive the turntable 16 to rotate in the horizontal direction, so that the camera 12 can monitor images in all angle ranges in the horizontal direction; The tilting action enables the camera 12 to monitor various viewing angles in the vertical direction. That is, the external environment of the dome camera is all within the monitoring range of the camera 12 .

FIG. 4 shows another embodiment of the present invention. A ball bearing 47 is arranged around the base 60 to carry the turntable 46, which can make the turntable 46 rotate more stably and make the image captured by the camera clearer and more stable.

The outer cover 50 is fixed on the turntable 46 , in order to obtain a clearer image, the outer cover 50 is provided with a groove 52 corresponding to the vertical pitch path of the lens 42 of the dome camera 40 . When the lens rotates left and right, the outer cover 50 also rotates accordingly, and the lens 42 directly captures the external image through the groove 52 to obtain a clearer image.

The dome camera body 40 can also be provided with a sound-collecting microphone, so that various situations on the spot are under control.

The main feature of the utility model is that it can monitor in a wide range. Therefore, for relatively open places, such as parks and roads, the utility model is particularly suitable. For general stores, shopping malls, or intercom monitors in buildings, it can also eliminate the dead angle of the monitoring range and give full play to the monitoring function.

Another feature of the utility model lies in its simple structure, easy assembly, relatively cheap manufacturing cost and low failure rate.
