The first body of the first shielding sheet 6 includes a connection end 61, a rotation end 65, and a shielding portion 62, wherein the connection end 61 is rotatably connected to the base 9. The rotating end 65 can rotate centering on the connecting end 61. The connecting end 61 and the rotating end 65 have a concave surface C and a convex surface D therebetween, wherein the shielding portion 62 is located on the convex surface D between the connecting end 61 and the rotating end 65 and protrudes outward.
The first body of the second shutter 7 includes a connection end 71, a rotation end 75, and a shutter portion 72, wherein the connection end 71 is rotatably connected to the base 9. The rotating end 75 can rotate centering on the connecting end 71. The connecting end 71 and the rotating end 75 have a concave surface C and a convex surface D therebetween, wherein the shielding portion 72 is located on the convex surface D between the connecting end 71 and the rotating end 75 and protrudes outward.
The opening areas of the first shielding sheet 6 and the second shielding sheet 7 formed when the shielding portion 62 and the shielding portion 72 in the working position completely open the through hole 16 are not smaller than the area of the through hole 16, so that the first shielding sheet 6 and the second shielding sheet 7 can completely open the lens 21 in the non-working position without blocking the shooting field of view of the lens 21. The shielding areas formed by the first shielding piece 6 and the second shielding piece 7 when the shielding part 62 and the shielding part 72 of the working position completely shield the through hole 16 are not smaller than the area of the through hole 16, so as to completely shield the field of view of the lens 21.
In one embodiment, the connecting end 61 of the first shielding plate 6 has a round hole 63 and a waist-shaped hole 64, and the first shielding plate 6 is sleeved outside the mounting post 91 of the base 9 through the round hole 63 and is rotatably connected to the base 9.
The connecting end 71 of the second shielding piece 7 is provided with a round hole 73 and a waist-shaped hole 74, and the second shielding piece 7 is sleeved outside the mounting column 93 of the base 9 through the round hole 73 on the second shielding piece and is connected to the base 9 in a rotatable manner.
The power output end 92 of the rotary driving mechanism 10 sequentially penetrates through the guide hole 96 on the base 9, the waist-shaped hole 64 on the first shielding piece 6 and the waist-shaped hole 74 on the second shielding piece 7 from inside to outside, the power output end 92 is in clearance fit with the guide hole 96, the power output end 92 is in interference fit with the waist-shaped hole 64 and the waist-shaped hole 74, and the power output end 92 moves along the extending direction of the guide hole 96 to drive the first shielding piece 6 and the second shielding piece 7 to rotate in the opposite direction or in the opposite direction.
Preferably, the center line O of the guide hole 96 has an arc shape centered on the mounting post of the base 9 to which the circular hole of one of the first and second shielding plates 6 and 7 is connected. For example, in fig. 11, the center line of the guide hole 96 is centered on the first mounting post 91 of the base 9 connected to the circular hole of the first shielding plate 6. The reason for this mounting is: the rotation drive mechanism 10 in this embodiment is disposed on one side of the first mounting post 91, and relatively away from the second mounting post 93 of the base 9 to which the circular hole in the second shutter 7 is attached. Of course, in the case where the rotation drive mechanism 10 is disposed on the side of the second mounting post 93 relatively far from the first mounting post 9 of the base 9 to which the circular hole on the second shielding sheet 7 is connected, the center line of the guide hole 96 may be set with the second mounting post 93 of the base 9 to which the circular hole on the first shielding sheet 6 is connected as the center.
As shown in FIG. 7, in one embodiment, the rotary drive mechanism 10 includes a yoke 14, a current coil 12, and a toggle 133, wherein:
the yoke 14 is U-shaped with an opening.
The current coil 12 has a wire terminal 15, and the wire terminal 15 is electrically connected to a PCB main board in the camera. The current coil 12 is provided on one side of the yoke 14. The current coil 12 is wound with a certain number of turns of coil, and the diameter of the coil is R.
The toggle handle 13 is provided with a mounting column 131, a ring magnet 132 and a toggle rod 133, the mounting column 131 is arranged at the opening of the yoke 14, the ring magnet 132 is sleeved outside the mounting column 131 in a clearance fit manner with the mounting column 131, one end of the toggle rod 133 is fixedly connected to the ring magnet 132, and the other end is provided with a power output end 92 of the rotation driving mechanism 10 and extends out of the opening of the yoke 14.
The rotation driving mechanism 10 provided in this embodiment is an electromagnetic switching device, and is driven by electromagnetism, so that the operation is simple and easy, and the cost is low. The present embodiment can change the magnetic force generated by the yoke 14 by changing the magnitude or direction of the current fed to the current coil 12, and the ring magnet 132 is attracted or repelled by the magnetic force of the yoke 14 and rotates clockwise or counterclockwise around the mounting post 131, so as to drive the shift lever 133 to rotate around the mounting post 131, and further the power output end 92 rotates around the mounting post 131. Then, in order to ensure that the arc shape of the center line of the guide hole 96 is centered on the first mounting post 91 of the base 9 to which the circular hole on the first shielding plate 6 is connected, the first mounting post 91 and the mounting post 131 are located on the same straight line parallel to the optical axis of the lens.
Such as: the wire terminal 15 is energized with a positive current, the coil of the current coil 12 generates an electromagnetic field, the lever 133 begins to rotate clockwise, and the power take-off 92 on the lever 133 rotates from position a to position B (equilibrium position). In this process, the power output end 92 pulls the first shutter piece 6 and the second shutter piece 7 from the open state to the closed state. At this time, the lens 21 of the camera is shielded by the first shielding sheet 6 and the second shielding sheet 7.
The reverse current is applied to the wire terminal 15, the coil of the current coil 12 generates an electromagnetic field, the lever 133 starts to rotate counterclockwise, and the power output 92 on the lever 133 rotates from position B to position a (equilibrium position). In this process, the power output end 92 pulls the first and second shutter pieces 6 and 7 from the closed state to the open state. At this time, the lens 21 of the camera is exposed to the field of view, and the first shielding sheet 6 and the second shielding sheet 7 are not in the field angle of the lens, i.e. the operation of the camera is not affected.
The rotary driving mechanism 10 is arranged in the mounting cavity of the base 9, so that the volume of the shielding device can be reduced. The wire terminal 15 of the rotation driving mechanism 10 is connected to a main board inside the camera, and an electric signal is given to the shielding device through the main board inside the camera, so that the first shielding piece 6 and the second shielding piece 7 are controlled to be switched between the working state and the non-working state.
In one embodiment, the base 9 has a second body in the shape of a dome comprising a bottom surface 97 and side surfaces 98, wherein:

The first end limiting protrusion 910 and the second end limiting protrusion 911 are symmetrically disposed with respect to the center line O, and limit the outward movement position when the rotation end 65 of the first shielding plate 6 and the rotation end 75 of the second shielding plate 7 rotate toward each other, respectively. The center line O is a line connecting the midpoint O1 of the first and second mounting posts 91 and 93 and the center O2 of the through hole 16.
The movement tracks of the first shielding piece 6 and the second shielding piece 7 can be controlled by the first shielding part limiting protrusion 94, the second shielding part limiting protrusion 95, the first end limiting protrusion 910 and the second end limiting protrusion 911.
