Technical Field

[0002] With the development of technology and the increase in demand, the application of 360-degree rotating cameras is becoming more and more extensive. The existing 360-degree rotating cameras mainly include a pan-tilt base and a camera module installed on the pan-tilt base along the axial direction of the pan-tilt base. When in use, the camera module rotates one circle in the clockwise direction and then rotates counterclockwise.

[0003] At present, the rotation of a 360-degree rotating camera is limited by a limiting structure. No matter it rotates clockwise or counterclockwise, it will stop when it rotates to the position of the limiting structure. There is a rotation error and it cannot truly reach 360 degrees. It needs to be compensated by the field of view of the camera of the camera module. This requires the camera of the camera module to have a larger field of view. When the field of view of the camera of the camera module is small, there will be a visual blind spot, which seriously affects the user's use. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] Figures 1 to 3 It is a structural schematic diagram of a 360-degree rotating camera of the utility model, wherein: Figure 1 The vertical cross-sectional structure diagram of the 360-degree rotating camera of the utility model is shown. Figure 2 The figure shows a cross-sectional structural diagram of the 360-degree rotating camera of the present invention at the extreme position of clockwise rotation. Figure 3 The figure shows a cross-sectional structural schematic diagram of the 360-degree rotating camera of the present invention at the extreme position of counterclockwise rotation. For ease of understanding, only the parts related to the present invention are shown in the figure.

[0023] Depend on Figure 1 , Figure 2 and Figure 3 It can be seen that the 360-degree rotating camera of the utility model includes a pan-tilt base 10, a camera module 20 rotatably mounted on the pan-tilt base 10, and a rotating driving mechanism arranged inside the pan-tilt base 10 for driving the camera module 20 to rotate. The camera module 20 is provided with a rotating mounting structure inserted into the pan-tilt base 10, and also includes a rotating limit slider 31 slidably mounted on the peripheral side of the rotating mounting structure, a sliding limit structure arranged between the rotating limit slider 31 and the pan-tilt base 10, a rotating toggle member 50 fixed to the rotating mounting structure, and a rotating limit slider 31 fixed to the rotating limit slider 31 and capable of rotating with the rotating toggle member 50. The engaging / separating sliding toggle member 32 has a first limit position 80 for limiting the rotation of the camera module 20 in the clockwise direction and a second limit position 90 for limiting the rotation of the camera module 20 in the counterclockwise direction between the rotating limit slider 31 and the sliding limit structure. The sliding toggle member 32 is arranged between the first limit position 80 and the second limit position 90. After the rotating toggle member 50 rotates in the clockwise direction and engages with the sliding toggle member 32, it can push the rotating limit slider 31 to slide. After the rotating toggle member 50 rotates in the counterclockwise direction and engages with the sliding toggle member 32, it can push the rotating limit slider 31 to slide in the opposite direction.

[0024] When in use, the rotating driving mechanism drives the camera module 20 to rotate, and the rotating toggle member 50 rotates synchronously with the camera module 20. After the rotating toggle member 50 is fitted with the sliding toggle member 32, the rotating limit slider 31 can be pushed to slide through the sliding toggle member 32. Since there is a first limit position 80 for limiting the camera module 20 to rotate in a clockwise direction and a second limit position 90 for limiting the camera module 20 to rotate in a counterclockwise direction between the rotating limit slider 31 and the sliding limit structure, and the sliding toggle member 32 is arranged between the first limit position 80 and the second limit position 90, the sliding toggle member 32 can slide between the first limit position 80 and the second limit position 90, and the camera module 20 rotates in a clockwise / counterclockwise direction. When rotating counterclockwise, the rotating toggle member 50 can rotate from the range between the first extreme position 80 and the second extreme position 90 to the range between the first extreme position 80 and the second extreme position 90, and can slide within the range between the first extreme position 80 and the second extreme position 90 after the rotating toggle member 50 and the sliding toggle member 32 are fitted. The rotating toggle member 50 can achieve a 360-degree rotation, thereby enabling the camera module 20 to achieve a 360-degree rotation. The 360-degree rotating camera of the utility model can achieve a 360-degree rotation when rotating in the clockwise / counterclockwise direction, thereby solving the problem that the rotation angle of the existing 360-degree camera cannot reach 360 degrees, thereby avoiding the existence of a visual blind spot.
