In the process that the movable rocking handle 21 drives the movable blade 4 to rotate by taking the blade pivot 112 as a rotation center, the lower surface of the movable blade 4 is overlapped on the upper surface of the base boss 113 and the upper surface of the base arc-shaped flange 114; according to the invention, the movable blade 4 is supported by the base boss 113 and the base arc-shaped flange 114, so that the contact area between the lower surface of the movable blade 4 and the fixed base 11 can be effectively reduced, and further, the contact friction acting force when the movable blade 4 rotates is reduced, and the smoothness when the movable blade 4 rotates is improved.

As a preferred embodiment, as shown in fig. 2, 4, 5, 6, 7 and 8, the fixed base 11 is provided with a closing blade limit stopper wall 1151 corresponding to the closing limit flange 411 of the movable blade 4, and the fixed base 11 is provided with an opening blade limit stopper wall 1152 corresponding to the opening limit flange 412 of the movable blade 4; the fixed base 11 is provided with a closing rocking handle limit stop wall 1153 and an opening rocking handle limit stop wall 1154 corresponding to the rocking handle driving arm 212 of the movable rocking handle 21.

In the working process of the invention, when the bistable infrared thermal imaging vehicle-mounted shutter is in a closed state, the closing limit flanging 411 of the movable blade 4 is limited and abutted against the closing blade limit baffle wall 1151 of the fixed base 11, and the movable rocking handle 21 is limited and abutted against the closing rocking handle limit baffle wall 1153 of the fixed base 11; when the bistable infrared thermal imaging vehicle-mounted shutter is in an opening state, the opening limiting flanging 412 of the movable blade 4 is limited and abutted against the opening blade limiting blocking wall 1152 of the fixed base 11, and the movable rocking handle 21 is limited and abutted against the opening rocking handle limiting blocking wall 1154 of the fixed base 11.

For the double-limit structure design consisting of the rocking handle limit and the blade limit, when the movable blade 4 rotates to a closed state or an open state, the impact force at the limit positions of the movable blade 4, the movable rocking handle 21 and the fixed base 11 can be effectively reduced, and the service life of the double-limit structure is prolonged.

As a preferred embodiment, as shown in fig. 3, the center horizontal position of the movable magnet 22 is located below the center horizontal position of the U-shaped iron core 31.

Because the movable blade 4 and the center of the movable magnet 22 are in a staggered design, in the process of electrifying the wire wrapping component 3 and driving the magnet rocking handle component 2 to rotate, the magnetic force of the two iron core magnetic pole parts 312 of the U-shaped iron core 31 acts on the movable magnet 22, and the central horizontal plane position of the movable magnet 22 is positioned below the central horizontal plane position of the U-shaped iron core 31, namely, the movable magnet 22 always receives upward suction force F, the suction force F can ensure that the movable magnet 22 is in a state, so that the problem of Z-axis movement of the magnet rocking handle component 2 is avoided, and the purpose of improving the stability and reliability of the movement is further achieved.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
