Based on the above monitoring requirement, the second support 105 may include a plurality of sub-supports, wherein at least two sub-supports of the sub-supports are rotatably connected, so that the lens assembly 102 may be respectively disposed on the two sub-supports that rotate relatively, so as to satisfy the monitoring requirement of multiple angles. It will also be appreciated that the number of sub-mounts may match the number of lens assemblies 102, and that the sub-mounts provided with lens assemblies 102 may rotate relative to one another.

With continued reference to fig. 1 and 2, in an experimental scenario, due to the requirement of monitoring a human face and an experimental process, two lens assemblies 102 may be provided, and based on this, the second support 105 may include a first sub-support 105a and a second sub-support 105b, wherein the first sub-support 105a is rotatably connected to the first support 104 through the rotating connection portion 30, and the second sub-support 105b is rotatably connected to the first sub-support 105 a.

In one embodiment, the first sub-mount 105a can rotate within a range of 0 to 90 ° relative to the second sub-mount 105b, when the first sub-mount 105a is at 0 ° relative to the second sub-mount 105b and the first sub-mount 105a is at 0 ° relative to the first mount 104, the first sub-mount 105a overlaps the second sub-mount 105b, and the overlapped first sub-mount 105a and the overlapped second sub-mount 105b are horizontally aligned with the first mount 104. Of course, the rotation angle of the first sub-mount 105a with respect to the second sub-mount 105b is not limited thereto.

The cable 106 connected to the lens assembly 102 in the second sub-mount 105b passes through the first sub-mount 105a and is connected to the main board 26 in the first mount 104. the cable 106 needs to pass through a rotary connection structure connecting the second sub-mount 105b and the first sub-mount 105a and a rotary connection portion 30 connecting the first sub-mount 105a and the first mount 104.

In the embodiment shown in fig. 1 and 2, the rotation connecting structure for connecting the second sub-mount 105b and the first sub-mount 105a is the same as the rotation connecting portion 30, and the arrangement of the cable 106 at the rotation connecting structure (the same as the rotation connecting portion 30, and the rotation connecting portion 30 is used instead in the following) will be described below by taking the rotation connecting structure of the second sub-mount 105b and the first sub-mount 105a as an example.

Referring to fig. 3 to 5, fig. 3 is an exploded view of a part of the structure of the first and second sub-mounts in an expanded state; FIG. 4 is a sectional view of a portion of the first and second sub-stents in an expanded configuration; fig. 5 is a sectional view showing a part of the structure of the first and second sub-brackets in a folded state.

It is easy to understand that when the number of the redundant segments 40 surrounding the rotation axis of the rotation connection portion 30 is larger, the outer ring has stronger ability to relieve the pulling deformation, and the middle portion has relatively weaker ability to relieve the pulling deformation, so that the redundant segments 40 can surround two to three circles better, and occupy less space at the rotation connection portion 30.

In a practical application scenario, according to the minimum bending radius of the cable 106, the diameter of the circular receiving cavity may be set to be more than 1.5 times of the outer diameter of the ring of the redundant segment 40, wherein the ring of the redundant segment 40 is wound according to the minimum allowable bending radius of the cable 106. In a specific embodiment, for example, a cable with a diameter of 2mm to 3mm may be used, the allowable minimum bending radius of the cable 106 may be determined according to the specification of the cable 106, the diameter of the circular receiving cavity 31 may be set to be not less than 30mm to 35mm according to the allowable minimum bending radius, and the diameter of the redundant segment 40 around the rotation axis of the rotation connecting portion 30 may be not less than 30 mm.
