Current surveillance cameras typically employ complex gear systems for quick tilt adjustment, using knobs to change the camera's tilt angle. However, this existing technology suffers from structural complexity and high manufacturing costs.

[0004] Therefore, a video device with a relatively simple structure and low manufacturing cost needs to be designed. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0044] This embodiment provides a video device, including: a housing (100) having a shooting window (a) on one side; a camera assembly (200) rotatably mounted inside the housing (100), the lens (210) of which can acquire images through the shooting window (a); an angle adjustment plate (300) connected to the camera assembly (200) and rotating synchronously with the camera assembly (200); and a locking member for locking the angle adjustment plate (300) and the housing (100) to lock the relative angle of the camera assembly (200) inside the housing (100).

[0045] Please refer to Figure 1 and Figure 2 This utility model provides a video device 1000, which can be applied to parking lot management to achieve the purposes of image capture, license plate recognition, and parking space control. The video device 1000 includes: a housing 100, a camera assembly 200, an angle adjustment plate 300, and a locking component.

[0046] The outer casing 100 has a shooting window a on one side and an assembly cavity b inside. The outer casing 100 can be fixed to an external mounting base (not shown in the figure).

[0047] The camera assembly 200 is rotatably mounted within the housing 100, and its lens 210 can acquire images through the shooting window a. Optionally, the camera assembly 200 is rotatably mounted within the mounting cavity b of the housing 100. In this embodiment, the lens 210 of the camera assembly 200 protrudes from the shooting window a, thus enabling it to acquire images through the shooting window a. Of course, the lens 210 of the camera assembly 200 can also be located within the shooting window a, as long as it can acquire images through the shooting window a.

[0048] The angle adjustment plate 300 is connected to the camera assembly 200 and rotates synchronously with the camera assembly 200. That is, the angle adjustment plate 300 can rotate with the camera assembly 200, and the rotation angle of the angle adjustment plate 300 is the rotation angle of the camera assembly 200.

[0049] The locking element is used to lock the angle adjustment plate 300 and the housing 100 to lock the relative angle of the camera assembly 200 within the housing 100. That is, by locking the angle adjustment plate 300 to the housing 100, the locking element prevents the angle adjustment plate 300 from shifting relative to the housing 100, thereby locking the current deflection angle of the camera assembly 200.

[0050] The video device 1000 includes an angle adjustment plate 300 connected to and rotating synchronously with the camera assembly 200, and a locking member for locking the angle adjustment plate 300 and the housing 100. Thus, when the angle of the camera assembly 200 needs to be adjusted, it is only necessary to rotate the camera assembly 200 to the appropriate angle and then secure it with the locking member. Because this structure does not require a complex and costly gear system, it has the advantages of a simpler structure and lower manufacturing cost.

[0051] In another embodiment, one of the housing (100) and the angle adjustment plate (300) is provided with a fixing hole, and the other is provided with a limiting hole (o7) centered on the rotation center of the camera assembly (200); the locking member locks the angle adjustment plate (300) and the housing (100) through the fixing hole and the limiting hole (o7).

[0052] To achieve the locking angle adjustment plate 300 and the housing 100, optionally, please refer to... Figure 2 In one embodiment, the housing 100 is provided with a fixing hole, and the angle adjustment plate 300 is provided with a limiting hole o7 centered on the rotation center of the camera assembly 200. The distance between the fixing hole and the rotation center of the camera assembly 200 is equal to the distance between the limiting hole o7 and the rotation center of the camera assembly 200. Of course, in other embodiments, the fixing hole can also be provided on the angle adjustment plate 300, and the limiting hole o7 centered on the rotation center of the camera assembly 200 can be provided on the housing 100 accordingly. No specific limitation is made here. The locking member locks the angle adjustment plate 300 and the housing 100 through the fixing hole and the limiting hole o7. That is, the locking member locks the angle adjustment plate 300 and the housing 100 by locking the angle adjustment plate 300, preventing the angle adjustment plate 300 from displacing relative to the housing 100 and locking the current deflection angle of the camera assembly 200. In this embodiment, the limiting hole o7 is used to limit the movement angle and movement distance of the locking member within its hole, thereby avoiding the problem of excessive movement angle of the angle adjustment plate and movement deviating from the center.

[0053] Alternatively, please refer to Figure 1 and Figure 2 In this embodiment, both the housing 100 and the camera assembly 200 have elliptical cross-sections, meaning that the housing 100 and the camera assembly 200 are approximately ellipsoids. The shooting window a is an elliptical window. However, the specific shapes of the housing 100, the camera assembly 200, and the shooting window a are not limited to this, as long as the camera assembly 200 can rotate within the housing 100 without interference, and the lens 210 of the camera assembly 200 can acquire images through the shooting window a.

Optionally, please refer to Figure 2 and Figure 3 In this embodiment, the camera assembly 200 has pivots 220 on both sides, and the housing 100 has bearings 120 on both sides that match the pivots 220. This allows the camera assembly 200 to rotate relative to the housing 100 to adjust its pitch angle.

[0056] In another embodiment, the surface of the rotating shaft (220) is provided with a first anti-slip protrusion, and the inner surface of the shaft hole (o2) of the bearing seat (120) is provided with a second anti-slip protrusion that matches the first anti-slip protrusion.

Thus, during installation, the rotating shaft 220 of the camera assembly 200 can be first mounted on the lower bearing seat 121, and then the upper bearing seat 122 and the lower bearing seat 121 can be assembled. Specifically, in this embodiment, the upper bearing seat 122 and the lower bearing seat 121 are fixed by screws 800.

[0060] In another embodiment, the lower half-shaft seat (121) has a lower half-shaft hole (o3) and its upper end face has a guide slope (c) that is inclined downward from away from the shooting window (a) toward the lower half-shaft hole (o3); the upper half-shaft seat (122) has an upper half-shaft hole (o4) that matches the lower half-shaft hole (o3) and an assembly slope (d) that matches the guide slope (c).

The fixing hole is a screw hole o1 disposed on the bearing seat 120, and the locking element is a threaded fastener 400. Optionally, in this embodiment, one end of the angle adjusting plate 300 is inserted into the end of the rotating shaft 220 and fixed by a first fastener 320.

[0064] In another embodiment, one end of the limiting hole (o7) of the angle adjustment plate (300) is fan-shaped, and there is an avoidance groove (e) between the bearing seat (120) and the inner wall of the outer shell (100) to avoid the angle adjustment plate (300).

[0065] To avoid interference between the angle adjustment plate 300 and the inner wall of the outer casing 100, optionally, please refer to...
