[0031] Example:

[0032] See also Figure 1-Figure 5 The present embodiment provides a camera device, including a housing 1, a vibration absorber 2 and a shooting assembly 3, wherein the housing 1 includes a front housing 12 and a rear housing 13, the front housing 12 and the rear housing 13 are surrounded to form a mounting cavity, the shooting assembly 3 is mounted on the housing 1, a part of the shooting assembly 3 is located at the outer wall of the front housing 12 for normal shooting, and the rest of the shooting assembly 3 is located in the mounting cavity. The vibration absorber 2 is located in the mounting cavity and mounted on the shooting assembly 3.

[0033] The vibration absorber 2 is a prior art, and includes a power device and a damper. The power device may be a pneumatic device or an electric device. In this embodiment, the vibration absorber 2 can detect the change in the vibration frequency of the shooting component 3, and then the power device automatically adjusts the position of the damper to achieve anti-resonance, thereby reducing the amplitude of the shooting component 3 on the housing 1. The reduction in the amplitude of the shooting component 3 effectively increases the stability of its shooting position, thereby achieving the purpose of increasing the shooting quality.

[0034] In this embodiment, the outer wall of the housing 1 is provided with a first rotating shaft 11, and the camera device further includes a rotating bracket 4, and the rotating bracket 4 is provided with a first rotating hole, and the first rotating shaft 11 is passed through the first rotating hole, so that the housing 1 can be rotated on the rotating bracket 4 by relying on the first rotating shaft 11 to adjust the shooting angle of the camera device. Preferably, a first buffer ring 111 is sleeved on the first rotating shaft 11, and the first buffer ring 111 is located between the outer wall of the first rotating shaft 11 and the inner wall of the first rotating hole. The first buffer ring 111 can reduce the shaking of the first rotating shaft 11 when rotating, thereby improving the stability of the camera device during tracking and shooting.

[0035] In this embodiment, there are two first rotating shafts 11 which are coaxially arranged. Correspondingly, there are also two first rotating holes. The two first rotating shafts 11 are respectively passed through the two first rotating holes, so as to improve the stability of the housing 1 during rotation.

[0036] In this embodiment, the front shell 12 is detachably mounted on the rear shell 13 to allow the vibration absorber 2 to be replaced. The first rotating shaft 11 is located on the outer wall of the rear shell 13 and is fixed to the rear shell 13 (usually integrally formed), so that during the disassembly and assembly of the front shell 12 on the rear shell 13, the structure of the first rotating shaft 11 will not be disassembled and can still stay stably at the first rotating hole. Accordingly, during the replacement of the vibration absorber 2, it is not necessary to disassemble the entire housing 1 from the rotating bracket 4, but the front shell 12 can be directly disassembled at the rotating bracket 4.

[0037] See also Figure 4 and Figure 5 The shooting assembly 3 includes a heat sink 14, which is located in the installation cavity and fixed on the front shell 12, and the vibration absorber 2 is installed on the heat sink 14. Therefore, when the front shell 12 is removed from the rear shell 13, the vibration absorber 2 can also be removed together with the front shell 12, instead of falling directly from the installation cavity, thereby improving the safety of the disassembly process.

[0038] In order to realize the disassembly and assembly of the rear housing 13 on the rotating bracket 4, the rotating bracket 4 includes a rotating base 41 and a rotating cover 42. The rotating base 41 is provided with a first arc-shaped notch, and the rotating cover 42 is provided with a second arc-shaped notch 421. Both the first arc-shaped notch and the second arc-shaped notch 421 are semicircular notches. The rotating cover 42 is rotatably arranged on the rotating base 41, so that the rotating cover 42 has an open state and a closed state.

[0039] See also Figure 1 When the rotating cover 42 is in a closed state, the first arc-shaped notch and the second arc-shaped notch 421 are arranged to form a first rotating hole, and the side wall of the first arc-shaped notch and the side wall of the second arc-shaped notch 421 cooperate to clamp the first rotating shaft 11. On this basis, the two first rotating holes cooperate to prevent the housing 1 from detaching from the rotating bracket 4.

[0040] See also Figure 2 When the rotating cover 42 is in the open state, the second arc-shaped notch 421 is separated from the first rotating shaft 11, and the rotating cover 42 no longer blocks the first rotating shaft 11, so as to allow the first rotating shaft 11 to disengage from the first arc-shaped notch by radial movement.

[0041] See also Figure 3 , a second rotating shaft 411 is provided on the rotating base 41, and the second rotating shaft 411 is provided on the rotating cover 42. The second rotating shaft 411 and the first rotating shaft 11 are parallel and spaced apart, and the rotating cover 42 is rotatably connected to the rotating base 41 through the second rotating shaft 411. A torsion spring 412 is sleeved on the second rotating shaft 411, and the two ends of the torsion spring 412 are respectively abutted on the rotating base 41 and the rotating cover 42, and a locking screw 422 is provided on the rotating cover 42. When the rotating cover 42 is in a closed state, the torsion spring 412 is in a compressed state, and the locking screw 422 is threadedly connected to the rotating base 41 to overcome the elastic force of the torsion spring 412. When the locking screw 422 is loosened, the torsion spring 412 is restored, and the rotating cover 42 automatically switches from a closed state to an open state by rotating around the second rotating shaft 411.

[0042] In this embodiment, the rotating bracket 4 also includes a mounting plate 43 and a connecting arm 44. The two ends of the connecting arm 44 are respectively fixed to the rotating base 41 and one side of the mounting plate 43. The mounting plate 43 and the housing 1 are spaced apart to leave space for the housing 1 to rotate. The mounting plate 43 is provided with a mounting hole, and a fastening bolt 5 is provided at the mounting hole. Figure 6 The mounting plate 43 can be mounted on the wall by fastening bolts 5 to achieve wall mounting of the camera device. Figure 7 The mounting plate 43 can also be mounted on the ceiling by fastening bolts 5 to achieve the hanging installation of the camera device.

[0043] Preferably, the fastening bolts 5 and the mounting holes are clearance-fitted to allow fine adjustment of the mounting position of the mounting plate 43 .

[0044] Preferably, a buffer pad 431 is provided on one side of the mounting plate 43 away from the connecting arm 44. When the camera device is wall mounted, the buffer pad 431 is located between the wall and the mounting plate 43. When the camera device is suspended, the buffer pad 431 is located between the ceiling and the mounting plate 43.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
