Referring to fig. 1 and fig. 2 together, a monitoring device 100 is provided in an embodiment of the present utility model. The monitoring apparatus 100 includes a camera body 10, a rotator 20, a first rotation shaft 31, and a second rotation shaft 32. The rotor 20 includes a first runner 21 and a second runner 22. The first runner 21 is fixedly connected to an end of the second runner 22. The camera body 10 is connected to a side of the second runner 22 away from the first runner 21. The first rotating shaft 31 is in transmission connection with the first rotating wheel 21, and is used for driving the camera body 10 to rotate around the central axis of the first rotating wheel 21. The second rotating shaft 32 is in transmission connection with the second rotating wheel 22, and is used for driving the camera body 10 to rotate around the central axis of the second rotating wheel 22. Wherein the central axis of the first wheel 21 intersects the central axis of the second wheel 22. In this way, the first rotating shaft 31 can drive the camera body 10 to rotate around the central axis of the first rotating wheel 21 through the first rotating wheel 21, and the second rotating shaft 32 can drive the camera body 10 to rotate around the central axis of the second rotating wheel 22 through the second rotating wheel 22, so that the monitoring angle of the monitoring device 100 is adjusted, and the monitoring range of the monitoring device 100 is further improved.

It should be noted that fig. 2 is only for schematically describing the monitoring device 100, and does not constitute a limitation of the monitoring device 100, and the monitoring device 100 may include more or less components than those shown in fig. 2, or may be combined with some components, or different components, for example, the monitoring device 100 may further include a connection harness, a power source, or the like.

In this embodiment, the central axis of the first rotating wheel 21 is perpendicular to the central axis of the second rotating wheel 22, so that the camera body 10 can rotate up and down, left and right, so as to obtain a larger monitoring range. In the view angle shown in fig. 2, the first rotating shaft 31 and the first rotating wheel 21 are used for driving the camera body 10 to rotate up and down, and the second rotating shaft 32 and the second rotating wheel 22 are used for driving the camera body 10 to rotate left and right. In some embodiments, the central axis of the first rotating wheel 21 and the central axis of the second rotating wheel 22 may be disposed at an acute angle to adjust the rotation direction of the camera body 10.

Referring to fig. 2 and 3 together, in the present embodiment, the first shaft 31 and the second shaft 32 are configured as worms. The first wheel 21 and the second wheel 22 are configured as worm wheels that cooperate with a worm. The worm wheel and worm gear transmission mode is compact in structure, and self-locking can be formed between the worm wheel and the worm gear, namely, after the first rotating shaft 31 and the first rotating shaft 21 or the second rotating shaft 32 and the second rotating shaft 22 rotate the camera body 10 to a preset angle, the first rotating shaft 31 or the second rotating shaft 32 does not need to continuously provide driving force for the first rotating shaft 21 or the second rotating shaft 22, and the camera body 10 can be kept relatively fixed through the self-locking effect of the worm wheel and the worm gear, so that the power consumption of the monitoring equipment 100 is reduced. In some embodiments, the first and second shafts 31 and 32 may be configured as the same worm to simplify the structure of the monitoring apparatus 100, and improve interchangeability of the first and second shafts 31 and 32, thereby reducing the production cost of the monitoring apparatus 100.

The central angle corresponding to the first tooth surface 211 may be an angle that the first rotating shaft 31 can rotate to drive the first rotating wheel 21. The angle by which the camera body 10 can rotate around the central axis of the first rotating wheel 21 corresponds to the magnitude of the central angle corresponding to the first tooth surface 211. In some embodiments, the central angle corresponding to the first tooth surface 211 may also be other angles, such as 170 °, 160 °, 150 °, 90 °, and the like.

In some embodiments, the first runner 21 and the second runner 22 may be configured as a split structure. The first rotating wheel 21 and the second rotating wheel 22 can be fixedly connected together in a bonding, clamping, welding, screwing and other modes.

The two connecting portions 512 are substantially inverted-shaped with respect to the support shaft 52. In some embodiments, the fixing bracket 51 may not include the connection portion 512, i.e., at least one end portion of the support shaft 52 is directly connected with the body portion 511.

The monitoring device 100 further comprises a support plate 41. The support plate 41 is rotatably connected to the second runner 22. The camera body 10 is connected to the second runner 22 through a support plate 41. The support plate 41 is located between the camera body 10 and the second runner 22.

The second driver 34 is fixedly connected with the support plate 41 and is in transmission connection with the second rotating shaft 32. When the monitoring device 100 needs to adjust the monitoring angle, the controller in the monitoring device 100 may control the first driver 33 and/or the second driver 34 to work and drive the first rotating shaft 31 and/or the second rotating shaft 32 to rotate, so that the rotating body 20 drives the camera body 10 to rotate. Specifically, the first driver 33 may drive the rotator 20 to rotate around the central axis of the first rotating wheel 21 through the first shaft 31, so as to drive the camera body 10 to rotate around the central axis of the first rotating wheel 21. The second driver 34 may rotate the rotor 20 around the central axis of the second rotating wheel 22 through the second rotating shaft 32. When the second rotating shaft 32 rotates, the second rotating shaft 32 receives the reaction force of the second rotating wheel 22, and drives the supporting plate 41 to rotate around the central axis of the second rotating wheel 22 through the second driver 34, so that the camera body 10 is driven to rotate around the central axis of the second rotating wheel 22 through the supporting plate 41.
