Please refer to FIG. 3 and FIG. 10 at the same time, the shield 100 further includes a housing 900 disposed above the base 200 to cover the shielding part 400 , the wire winding assembly 300 and the base 200 in sequence. The casing 900 has an opening 910 , a plurality of casing sidewalls 920 and a plurality of first connecting portions 930 . The shielding side 420 of the shielding portion 400 is used to shield the opening 910 . The plurality of casing sidewalls 920 extend toward the base 200 . The plurality of first connection portions 930 are located on the lower side of the plurality of housing sidewalls 920 , and the base 200 has a plurality of second connection portions 240 corresponding to the plurality of first connection portions 930 . In this way, when the user presses the shutter 100 of the present invention due to improper force application, the pressure exerted by the user will be directly transmitted to the bottom 210 of the base 200 through the side wall 920 of the housing 900, and the housing 900 is not easy to deform under pressure and press against the shielding part 400, so the external force applied to the housing 900 will not spread to the shielding part 400 arranged inside, thereby preventing the shielding part 400 from being stuck on the cord winding assembly 300 due to pressure mobile problem.

As shown in FIG. 10 , the plurality of second connecting portions 240 of the base 200 are recessed at the bottom 210 of the base 200, and the plurality of first connecting portions 930 are protruded downward on the lower surface 922 of the side wall 920 of the housing. The portions 930 respectively enter into the corresponding plurality of second connecting portions 240 , and the lower surface 922 of the housing sidewall 920 abuts against an upper surface 212 of the bottom 210 . Through the above arrangement, when the housing 900 is pressed or impacted by an external force, the external force can be transmitted to the base 200 without pressing or spreading to the shielding part 400 provided inside the housing 900, thereby preventing the shielding part 400 from being pressed. The problem of being stuck on the reel assembly 300 and unable to move.

In addition, the plurality of first connecting parts 930 of the housing 900 can be bonded to the plurality of second connecting parts 240 of the base 200 through a plurality of adhesives 250, thereby strengthening the fixed relationship between the housing 900 and the base 200 and increasing the resistance to external forces.

In some embodiments, the base 200 has two side walls 220 disposed on two sides of the bottom 210 , and the housing side walls 920 can be adjacent to the corresponding side walls 220 , so the applied pressure can also be transmitted to the side walls 220 of the base 200 . , so that the side wall 220 can support the housing side wall 920 to prevent the housing side wall 920 from being deformed under pressure.

Please refer to Fig. 5 and Fig. 6 again, because the first magnet 500 that the shutter 100 has is arranged on the first surface 410 of the shielding part 400 (that is: the surface of the shielding part 400 facing the winding assembly 300), it is located on the winding seat. The magnetically conductive sheet 320 in 310 can generate a magnetic attraction effect with the first magnet 500 , so that the magnetically conductive sheet 320 and the first magnet 500 attract each other, thereby positioning the shielding portion 400 in the vertical direction. For example, the magnetic attraction force between the magnetic conductive sheet 320 and the first magnet 500 will cause a certain degree of friction force between the first surface 410 of the shielding part 400 and the upper side of the side wall 220, and the winding assembly 300 is activated by the applied current. The generated magnetic field will generate a force that drives the first magnet 500 to move in the first direction or the second direction. When the static friction force is maximum, the shielding part 400 can be moved; when the winding assembly 300 is not applied with current, the magnetic attraction between the magnetic conductive sheet 320 and the first magnet 500 can change the relative position of the shielding part 400 and the side wall 220 fixed. For example, when the shielding part 400 moves to the position where its shielding side 420 shields the camera, the magnetic attraction between the magnetically conductive sheet 320 and the first magnet 500 can keep the shielding side 420 at the position of shielding the camera, and it is not easy to Shaking or vibrating causes the shielding part 400 to move. At the same time, through the normal support of the buckle 600 by the supporting elastic body 800, the buckle end 610 of the buckle 600 will be snapped into the first groove 440 of the shielding part 400, thereby completely restricting the shielding part 400, so when the first current or the second current is not applied to the wire winding assembly 300, the wire winding assembly 300 will not form a magnetic field to drive the first magnet 500 to drive the shielding part 400 to move in the first direction or the second direction, and the wire winding assembly 300 will not form a magnetic field to drive the second magnet 700 to move the buckle 600 away from the shielding part 400, so the shielding part 400 at this time will be fixed due to the normal support of the supporting elastic body 800 on the buckle 600 , to avoid possible shaking or shifting of the shielding part 400 when the first current or the second current is not applied to the winding assembly 300 .

To sum up, the shutter 100 of the present invention can control the movement and positioning of the shielding part 400 in the horizontal direction by the principle of magnetic attraction through automatic control, thereby performing the revealing and shielding operations of the camera and simplifying its assembly structure and components quantity. In addition, the positioning of the shielding portion 400 in the vertical direction can also be accurately completed through the magnetic attraction force of the magnetic conductive sheet 320 to the first magnet 500 . Furthermore, the cooperation between the buckle 600 and the supporting elastic body 800 can effectively achieve the action of buckling and fixing the shielding part 400, ensuring that the shielding part 400 can be closed when the first current or the second current is not applied to the winding assembly 300. The 400 doesn't exhibit any wobble or offset.
