Through setting up pivot setting element 2 for the rotation of swinging 3 uses pivot post 21 on the pivot setting element 2 as the center, makes swinging 3 and mount pad 1 can not direct contact, thereby has avoided the vibration that the rotation produced directly to transmit to mount pad 1, has effectively eliminated the vibration of shutter during operation, is applicable to the higher occasion of stationarity requirement, like the aircraft cloud platform, has guaranteed the definition of formation of image.

Preferably, the rotating shaft positioning part 2 is made of elastic material. Therefore, the rotating shaft positioning piece 2 made of elastic material utilizes the elastic deformation characteristic of the elastic material, when the swinging piece 3 rotates to generate impact on the rotating shaft column 21, the impact is relieved through the elastic action of the elastic material, so that the generation of vibration is reduced, and the vibration during the operation of the shutter is further eliminated.

Preferably, referring to fig. 5, the rotating shaft positioning element 2 is further provided with a plurality of positioning portions 22 protruding in the direction of the mounting groove 12, the mounting seat 1 is further provided with a positioning groove 13 matched with the positioning portions 22, and the fixing of the rotating shaft positioning element 2 and the mounting seat 1 is realized through the correspondence between the positioning portions 22 and the positioning grooves 13, so as to facilitate the mounting. Furthermore, because the rotating shaft positioning piece 2 is made of elastic material, the outer diameter of the positioning portion 22 can be set to be larger than the inner diameter of the positioning groove 13, and the rotating shaft positioning piece 2 and the mounting base 1 can be tightly fixed through the elastic deformation characteristic of the elastic material.

Preferably, a mounting cavity 14 is formed in the mounting seat 1, and the rotating shaft positioning piece 2 is arranged in the mounting cavity 14, so that the edge of the rotating shaft positioning piece 2 abuts against the inner side of the mounting cavity 14, thereby limiting the rotating shaft positioning piece 2 in the mounting seat 1, and avoiding the rotating shaft positioning piece 2 from displacing under the rotating action of the swinging piece 3 to influence the reliability of the shutter action; the installation groove 12 is opened in the installation cavity 14, so that after the rotating shaft positioning part 2 is installed, the driving assembly and the swinging part 3 can be located in the installation groove 12, and the internal structure of the shutter is more compact.

Preferably, the driving assembly comprises an iron core 51, a coil 52 and a permanent magnet 53, wherein the iron core 51 is arranged in the mounting groove 12, the coil 52 is wound on the iron core 51, the permanent magnet 53 is arranged at one end of the iron core 51, and the permanent magnet 53 is sleeved outside one end of the swinging member 3. Therefore, by adopting a driving assembly formed by the iron core 51, the coil 52 and the permanent magnet 53, the swinging of the swinging piece 3 can be controlled by controlling the energization of the coil 52, so that the shutter blades 4 are driven to complete the action of shielding or being far away from the light through hole 11.

Preferably, the vibration damping shutter further comprises a middle cover 6 and a bottom cover 7, the middle cover 6 is arranged at the bottom of the rotating shaft positioning element 2, the bottom cover 7 is arranged below the middle cover 6, the shutter blades 4 are arranged between the middle cover 6 and the bottom cover 7, buckling holes 61 are formed in the middle cover 6 and the bottom cover 7, the rotating shaft positioning element 2 is provided with a connecting pin 23, and the middle cover 6 and the bottom cover 7 are buckled with the mounting seat 1 through the corresponding buckling holes 61 and the connecting pin 23. The middle cover 6 is arranged for separating the shutter blade 4 from the rotating shaft positioning piece 2, the rotating shaft positioning piece 2 is prevented from influencing the action of the shutter blade 4, and the bottom cover 7 is buckled with the mounting seat 1 and used for limiting the shutter blade 4 between the middle cover 6 and the bottom cover 7, so that the internal structure of the shutter is more compact. The middle cover 6 and the mounting base 1 and the bottom cover 7 and the mounting base 1 are fixed by the corresponding connection pins 23 and the corresponding buckling holes 61.

Further, referring to fig. 2, a boss 24 is further disposed on the rotating shaft positioning element 2, one side of the boss 24 abuts against the edge of the middle cover 6, and the bottom of the boss 24 is attached to the bottom cover 7. Thus, by providing the boss 24, there is a difference in height between the middle cap 6 and the bottom cap 7, so that a space for accommodating the shutter blade 4 is formed between the middle cap 6 and the bottom cap 7. In addition, the arrangement of the boss 24 also increases the contact area between the rotating shaft positioning piece 2 and the inner wall of the mounting seat 1, so that a better vibration reduction effect is achieved, and the vibration is further prevented from being transmitted to the mounting seat 1.
