Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1, a shielding portion 400 of the shielding device 100 of the present application can shield an opening 910 of a housing 900 when the shielding device is in a closed state. As shown in fig. 2, when the shutter 100 is in the open state, the shielding portion 400 moves to shield the opening 910 of the housing 900. In some embodiments, the shielding portion 400 may be used to shield or expose a camera (not shown), for example, the shielding portion 400 shields the opening 910 of the housing 900, so as to shield the camera, so that the camera cannot take images to the outside; the shielding portion 400 moves to no longer shield the opening 910 of the housing 900, so that the camera can be exposed from the opening 910 of the housing 900 for capturing an external image.

Please refer to fig. 3, which is an exploded view of the shelter 100 of the present application. As shown in the drawings, the shielding device 100 includes a base 200, a winding assembly 300, a shielding portion 400, a first magnet 500, a locking member 600, and a second magnet 700.

The base 200 has a bottom 210 and two sidewalls 220 disposed at two sides of the bottom 210, and the bottom 210 and the two sidewalls 220 define a receiving space 230. The winding assembly 300 is disposed in the accommodating space 230. The shielding portion 400 is disposed in the accommodating space 230 and corresponds to the winding assembly 300. The first magnet 500 is disposed on the magnetic side 430 of the shielding portion 400 and on the first surface 410 of the shielding portion 400. The locking member 600 has a locking end 610, and the locking end 610 is located at a side of the wire winding assembly 300 and is used for locking the shielding part 400. The second magnet 700 is disposed on the locking member 600.

With the above arrangement, when a first current passes through the winding assembly 300 to form a first magnetic field, the first magnetic field drives the first magnet 500 to move the shielding portion 400 in the first direction, and the shielding side 420 of the shielding portion 400 shields the camera. When a second current passes through the wire winding assembly 300 to form a second magnetic field, the second magnetic field drives the first magnet 500 to move the shielding portion 400 in a second direction, and the shielding side 420 of the shielding portion 400 is away from the camera to expose the camera. Moreover, the first magnetic field and the second magnetic field can also drive the second magnet 700 to make the fastener 600 close to or far away from the shielding part 400.

In other words, the magnetic field provided by the winding assembly 300 interacts with the first magnet 500 to control the movement of the shielding part 400 in the horizontal direction, and the fastening member 600 is configured to fasten the shielding part 400 upward in a normal state, so as to prevent the shielding part 400 from shaking or shifting when the shielding device 100 is impacted by an external force.

The shelter 100 of the present invention further comprises a supporting elastic body 800. The supporting elastic body 800 is disposed on the base 200. The supporting elastic body 800 is configured to push the locking element 600 to link the locking end 610 of the locking element 600 to lock the shielding portion 400, wherein the shielding portion 400 has a shielding side 420, a magnetic side 430 disposed opposite to the shielding side 420, and a first groove 440. The first magnet 500 is disposed on the magnetic side 430, and the first recess 440 is disposed adjacent to the magnetic side 430. When the first groove 440 of the shielding portion 400 moves to above the locking element 600, and the supporting elastic body 800 pushes the locking element 600 upwards to link the locking end 610 of the locking element 600 to approach the shielding portion 400, the locking end 610 of the locking element 600 is locked to the first groove 440 of the shielding portion 400. The first magnetic field and the second magnetic field drive the second magnet 700 to make the locking element 600 far away from the shielding part 400, and are used for linking the locking end 610 of the locking element 600 to leave the first groove 440 to release the locking of the shielding part 400.

Referring to fig. 4 and 5, the shielding portion 400 may include a bump 412. The protrusion 412 is protruded from the shielding portion 400 toward the first surface 410 of the winding assembly 300. After the assembling of the shielding device 100 is completed, the protrusion 412 is located in the accommodating space 230 of the base 200, and the first magnet 500 is disposed in the slot 412a of the protrusion 412.

Through the above arrangement, neither the protrusion 412 of the shielding portion 400 nor the first magnet 500 directly contact with the base 200 during the moving process, so as to effectively reduce the friction force that the shielding portion 400 may be subjected to during the operation process.

When the first magnet 500 is disposed in the slot 412a of the bump 412, the first magnet 500 can be fixed in the slot 412a by gluing or embedding.

As shown in fig. 5 and 6, the shielding portion 400 further has a first groove 440, and the first groove 440 is disposed adjacent to the magnetic attraction side 430. When the first groove 440 of the shielding portion 400 moves to above the locking element 600, and the supporting elastic body 800 pushes the pushing end 620 of the locking element 600 upwards to link the locking end 610 of the locking element 600 to approach the shielding portion 400, the locking end 610 of the locking element 600 is locked in the first groove 440 of the shielding portion 400.

That is, as shown in fig. 6, when the shielding device 100 of the present application is in a state of shielding the camera, the shielding side 420 of the shielding portion 400 moves to a position below the opening 910 of the housing 900, and the first recess 440 of the shielding portion 400 moves to a position above the locking element 600 and is locked by the locking end 610 of the locking element 600. Since the first recess 440 of the shielding portion 400 is already engaged by the engaging end 610 of the engaging member 600, even if the shielding device 100 is impacted by an external force, the shielding portion 400 therein is engaged by the engaging member 600, thereby effectively avoiding the shaking or shifting of the shielding portion 400.

On the other hand, the shielding portion 400 may further have a second groove (not shown), which may be adjacent to the shielding side 420 of the shielding portion 400. When the second groove of the shielding portion 400 moves to above the fastening element 600, and the supporting elastic body 800 pushes the pushing end 620 of the fastening element 600 upwards to link the fastening end 610 of the fastening element 600 to approach the shielding portion 400, the fastening end 610 of the fastening element 600 is fastened to the second groove of the shielding portion 400.

In other words, when the shutter 100 of the present application is in the state of opening the camera, the shielding side 420 of the shielding portion 400 moves away from the opening 910 of the housing 900, and the second groove of the shielding portion 400 moves to the upper side of the locking member 600 and is locked by the locking end 610 of the locking member 600. Since the second groove of the shielding part 400 is already engaged by the engaging end 610 of the engaging member 600 at this time, even if the shielding device 100 is impacted by external force, the shielding part 400 therein is engaged by the engaging member 600, thereby effectively avoiding the shaking or shifting phenomenon of the shielding part 400.

As shown in fig. 6 and 7, the latch 600 further has a pushing end 620 extending downward from the latching end 610. The pushing end 620 is located at the lower side of the wire winding assembly 300, the second magnet 700 is disposed at the buckling end 610 or the pushing end 620, and the supporting elastic body 800 is configured to push the pushing end 620 upward. That is, the supporting elastic body 800 normally pushes upward the pushing end 620 of the locking element 600 without being subjected to other forces, so as to link the locking end 610 of the locking element 600 to normally push upward the shielding portion 400.

As shown in fig. 7, the shielding device 100 of the present application further includes a third magnet 710. When the second magnet 700 is disposed at the fastening end 610 of the fastening element 600, the third magnet 710 can be disposed at the pushing end 620 of the fastening element 600. Alternatively, when the second magnet 700 is disposed at the pushing end 620 of the locking member 600, the third magnet 710 may be disposed at the locking end 610 of the locking member 600. The third magnet 710 can assist the locking element 600 to move in a direction away from the shielding part 400 to release the locking of the shielding part 400 when the locking element 600 is acted by the first magnetic field and the second magnetic field.

In an embodiment, the locking element 600 is an L-shaped locking element, the locking end 610 is a long side of the L-shaped locking element, and the pushing end 620 is a short side of the L-shaped locking element, so as to cooperate with the supporting elastic body 800 to obtain the best pushing effect, but not limited thereto. That is, the locking member 600 can be changed according to the appearance of the winding assembly 300 to obtain the best pushing effect.

In addition, as shown in fig. 11, the supporting elastic body 800 is preferably a U-shaped metal elastic sheet, one end of which is connected to the bottom 210 of the base 200, so that it can be disposed in a limited space between the pushing end 620 of the locking member 600 and the base 200, thereby satisfying the miniaturization requirement of the conventional shielding device 100. The supporting elastic body 800 has a first end 810, a second end 820 and a bending part 830. The bending portion 830 is used to connect the first end portion 810 and the second end portion 820, so that the limited space is utilized to provide a proper force to make the second end portion 820 upwardly prop against the pushing end 620 of the fastener 600. In some embodiments, the first end 810 is attached to the bottom 210 of the base 200. For example, the first end 810 may be secured to the bottom 210 of the base 200 by insert molding.

Referring to fig. 8 and 9, the shielding device 100 of the present application includes a winding assembly 300 including a winding base 310, a magnetic sheet 320, a first lead 330 and a second lead 340. In the present application, the wire winding base 310, the magnetic conductive sheet 320, the first lead 330 and the second lead 340 are combined through an Insert molding (Insert molding) step. In some embodiments, the winding base 310, the magnetic conductive sheet 320, the first lead 330 and the second lead 340 may also form an insert molding structure together, so that the magnetic conductive sheet 320, the first lead 330 and the second lead 340 may be accommodated inside the winding base 310 through a single molding step, and thus the insert molding structure formed through an insert molding manner has the advantages of high assembly precision and fast manufacturing efficiency.

As shown, the first lead 330 has a first winding end 332 and a first lead 334, the second lead 340 has a second winding end 342 and a second lead 344, and the first winding end 332 and the second winding end 342 are protruded below the winding base 310 and are parallel to each other for subsequent winding operation. In some embodiments, before the insert molding step, the magnetic conductive sheet 320 and the first lead 330 are formed by cutting and bending the same metal material, so that the manufacturing process is simplified; or, the magnetic conductive sheet 320 and the second lead 340 are formed by cutting and bending the same metal material; alternatively, the magnetic conductive plate 320, the first lead 330 and the second lead 340 are all formed by cutting and bending the same metal material.

Referring to fig. 8 and 9 again, the winding assembly 300 of the present application further includes a winding 350. The winding 350 can wrap the first winding end 332, the winding seat 310, and the second winding end 342 by being sequentially wound around the first winding end 332, the winding seat 310, and the second winding end 342. The winding 350 can also wrap the second winding end 342, the winding base 310, and the first winding end 332 in a manner of sequentially winding around the second winding end 342, the winding base 310, and the first winding end 332. In some embodiments, after the winding base 310, the magnetic conductive sheet 320, the first lead 330 and the second lead 340 are formed into an insert molding structure through a single molding step, the wire is sequentially wound on the insert molding structure through a winding step, so as to complete the manufacturing of the winding assembly 300, which is more simplified in manufacturing process. In some embodiments, the portion of the wire 350 wound around the first winding end 332 is welded to the first winding end 332, and the portion of the wire 350 wound around the second winding end 342 is welded to the second winding end 342. In some embodiments, since the winding base 310, the magnetic conductive plate 320, the first lead 330 and the second lead 340 are formed as a single insert molding structure, it is more convenient to automatically wind the winding wire 350 around the first winding end 332, the winding base 310 and the second winding end 342 by an automatic winding device.

In the present application, the first terminal 334 of the first lead 330 and the second terminal 344 of the second lead 340 may further extend from the same side of the wire winding base 310 and be accommodated in the side groove of the bottom portion 210. Extend through the same side of the first terminal 334 of the first lead 330 and the second terminal 344 of the second lead 340 and are opposite to each otherThe parallel arrangement can make the structure of the winding assembly 300 more compact, thereby reducing the overall volume of the shielding device 100, and making it more suitable for being installed in the existing light and thin typeA formula electronic product.

Referring to fig. 9 again, after the winding 350 is wound around the first winding end 332 of the first lead 330 and the second winding end 342 of the second lead 340, two solders 360 may be further disposed on the first winding end 332 having the winding 350 and the second winding end 342 having the winding 350, respectively, so as to strengthen the combination relationship between the winding 350 and the first and second winding ends 332 and 342.

Referring to fig. 3 and 10, the shielding device 100 further includes a housing 900, and the housing 900 is disposed above the base 200 to sequentially cover the shielding portion 400, the winding assembly 300 and the base 200. The housing 900 has an opening 910, a plurality of housing sidewalls 920, and a plurality of first connecting portions 930. The shielding side 420 of the shielding portion 400 is used for shielding the opening 910. A plurality of housing sidewalls 920 extend toward the base 200. The plurality of first connection portions 930 are located at the lower side of the plurality of case 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 shielding device 100 of the present application due to improper force application, the applied pressure is directly transmitted to the bottom 210 of the base 200 through the housing sidewall 920 of the housing 900, and the housing 900 is not easily pressed to deform and press the shielding portion 400, so that the external force applied to the housing 900 does not reach the shielding portion 400 disposed inside, thereby avoiding the problem that the shielding portion 400 cannot move due to being pressed and clamped on the wire winding assembly 300.

As shown in fig. 10, the plurality of second connecting portions 240 of the base 200 are recessed in the bottom portion 210 of the base 200, the plurality of first connecting portions 930 are downwardly and convexly disposed on the lower surface 922 of the housing sidewall 920, the plurality of first connecting portions 930 respectively enter the corresponding plurality of second connecting portions 240, and the lower surface 922 of the housing sidewall 920 abuts against the upper surface 212 of the bottom portion 210. With 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 affecting the shielding part 400 disposed inside the housing 900, thereby preventing the shielding part 400 from being locked on the winding assembly 300 by the pressure and being unable to move.

Also, the plurality of first connection portions 930 of the case 900 may be bonded to the plurality of second connection portions 240 of the base 200 by the plurality of bonding glues 250, thereby strengthening the fixed relationship between the case 900 and the base 200 and increasing durability when being struck by an external force.

In some embodiments, the base 200 has two sidewalls 220 disposed on two sides of the bottom 210, and the sidewall 920 of the housing can abut against the corresponding sidewall 220, so that the applied pressure can be transmitted to the sidewall 220 of the base 200, and the sidewall 220 can support the sidewall 920 of the housing to prevent the sidewall 920 of the housing from being deformed under pressure.

Referring to fig. 5 and 6 again, since the first magnet 500 of the shielding device 100 is disposed on the first surface 410 of the shielding portion 400 (i.e., the shielding portion 400 faces the surface of the winding assembly 300), the magnetic sheet 320 in the winding seat 310 and the first magnet 500 can generate a magnetic attraction effect, so that the magnetic 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 between the magnetic conductive sheet 320 and the first magnet 500 may generate a certain degree of friction between the first surface 410 of the shielding portion 400 and the upper side of the sidewall 220, and the magnetic field generated by the current applied to the winding assembly 300 may generate a force driving the first magnet 500 to move in the first direction or the second direction, and when the force is greater than the maximum static friction force generated by the magnetic attraction between the first surface 410 of the shielding portion 400 and the upper side of the sidewall 220 far from the bottom 210, the shielding portion 400 may move; when the winding assembly 300 is not applied with current, the shielding portion 400 and the sidewall 220 are fixed relative to each other by the magnetic attraction between the magnetic conductive sheet 320 and the first magnet 500. For example, when the shielding portion 400 moves to a position where the shielding side 420 shields the camera, the shielding side 420 can be maintained at the position where the camera is shielded by the magnetic attraction between the magnetic conductive sheet 320 and the first magnet 500, and the shielding portion 400 is not easily moved due to external shaking or vibration. Meanwhile, the fastening end 610 of the fastening element 600 is fastened to the first groove 440 of the shielding portion 400 by the support elastic body 800 in the normal propping manner of the fastening element 600, so that the movement of the shielding portion 400 is completely limited, and therefore when the winding wire assembly 300 does not apply the first current or the second current, the winding wire assembly 300 does not form a magnetic field to drive the first magnet 500 to drive the shielding portion 400 to move towards the first direction or the second direction, and the winding wire assembly 300 does not form a magnetic field to drive the second magnet 700 to drive the fastening element 600 to move towards the direction far away from the shielding portion 400, so that the shielding portion 400 is fixed by the support elastic body 800 in the normal propping manner of the fastening element 600, and the shielding portion 400 is prevented from shaking or shifting possibly occurring when the winding wire assembly 300 does not apply the first current or the second current.

In summary, the shielding device 100 of the present application can control the movement and positioning of the shielding part 400 in the horizontal direction by the magnetic attraction principle through an automatic control manner, thereby performing the exposure and shielding operations of the camera and simplifying the assembly structure and the number of components. In addition, the magnetic attraction of the magnetic conductive sheet 320 to the first magnet 500 can also precisely complete the positioning of the shielding portion 400 in the vertical direction. Furthermore, the engagement between the locking member 600 and the supporting elastic member 800 can effectively achieve the action of locking and fixing the shielding portion 400, thereby ensuring that the shielding portion 400 does not shake or shift when the winding assembly 300 is not applied with the first current or the second current.
