Detailed Description

The shielding apparatus and the electronic device using the same of the present invention will be described in further detail with reference to the following embodiments and the accompanying drawings. For convenient description, define an XYZ rectangular coordinate system, the utility model discloses electronic equipment's the direction of motion that shelters from the device is on a parallel with the X axle, and is close to the direction of Z axle positive side and is last, and the direction of being close to Z axle negative side is down.

The first embodiment is as follows:

as shown in fig. 1 to 4, in a preferred embodiment, the shielding device of the present invention is applied to an electronic device, not shown, for being disposed in front of a lens of an image capturing device of the electronic device, so as to shield the lens and expose the lens as required. The shield apparatus mainly includes a shield 10, a magnet 20 fixed to the shield 10, a supporter 30 for supporting the shield 10, a coil 40 wound in a hollow cylindrical shape, and a locking assembly 50.

The magnet 20 and the coil 40 form an electromagnetic driving component of the shielding device, at least a part of the magnet 20 is inserted into the inner peripheral side of the coil 40 wound into a hollow column shape, the winding axis of the coil 40 is parallel to the X axis, when the coil 40 is electrified, a magnetic field parallel to the X axis is generated inside the coil 40, the magnet 20 is pushed to move along the direction parallel to the X axis, and the magnet 20 drives the shielding piece 10 to move so as to realize shielding and releasing actions of the lens of the camera device. Specifically, when currents in opposite directions flow through the coils 40, the different magnetic fields generated can drive the magnet 20 to move along the X-axis in opposite directions, and thus the shutter 10 is moved. Since the magnet 20 is disposed on the inner peripheral side of the coil 40, the space inside the coil 40 is utilized to the maximum, so that the size of the shielding device can be reduced, and the thickness of the shielding device is mainly reduced. And the magnetic field inside the coil 40 is the largest and thus the energy loss is small, the same size coil can push a larger mass of shield. In order to achieve precise control, at least a portion of the magnet 20 should be positioned on the inner peripheral side of the coil 40 when the magnet 20 stops or moves at the two extreme positions.

In this embodiment, the shielding member 10 includes a shielding plate 11 and a fixing portion 12 connected to the shielding plate 11, and is preferably made of a light plastic material by integral molding. The shielding sheet 11 is a strip-shaped sheet, the plane where the shielding sheet 11 is located is defined to be parallel to the plane defined by the X axis and the Y axis, the long side of the shielding sheet is parallel to the X axis, the first end (end) 111 of the shielding sheet is connected to the fixing portion, and the second end 112 of the shielding sheet is a free end. A portion in close proximity to the second end 112 serves as a light shielding portion 114 for shielding the lens of the image pickup apparatus when the shutter 11 is moved to the shielding position. A groove 113 is formed on a surface of the light shielding portion 114 facing the lens of the image pickup device, and an opaque or semi-opaque film or sheet 115 is fixed in the groove 113. It is understood that in other embodiments, the opaque or semi-opaque film or sheet 115 may be omitted. In addition, in the present embodiment, two holes 116 and 117 are formed between the light shielding portion 114 and the first end 111 to be spaced from each other to serve as a snap-fit position. In particular, the width (dimension in the Y-axis direction) of the light shielding portion 114 is larger than the width of the portion from the light shielding portion 114 to the first end 111. Since the light shielding portion 114 needs to shield the lens, its width and length should be larger than the diameter of the lens, and the portion of the light shielding portion 114 to the first end 111 can be narrower, so that the mass of the shutter 10 can be reduced and it can be better moved.

Fixing portion 12 includes a first portion 121 extending from first end 111 of shield sheet 11 substantially perpendicularly to shield sheet 11, and a second portion 122 extending from a tip of first portion 121 in a direction parallel to the X axis, and second portion 122 does not overlap or overlaps only an end of shield sheet 11 in the Z axis direction. The first portion 121 is for positioning the second portion 122 lower than the shield sheet 11 in the Z-axis so that the second portion can be inserted into the inner peripheral side of the coil 40 when the upper end face of the coil 40 is flush with or slightly lower or slightly higher than the upper surface of the shield sheet 11, so that the sum of the heights of the shield 10 and the coil 40 as a whole in the Z-axis is not larger than the height of the coil 40 in the Z-axis. The second portion 122 may be sheet-like or substantially rectangular. The magnet 20 is in the form of a stick that may be attached under the second portion 122 or partially or fully embedded within the second portion 122. In this embodiment, the second portion 122 is rectangular, the lower portion thereof is formed with a groove, and the magnet 20 is embedded into the groove of the second portion 122 from the lower portion of the second portion 122 and partially exposed, compared with the second portion 122 which is in a sheet-like structure, the magnet has a larger adhesion area with the second portion, and a higher fixing strength, and the magnet is also easily mounted in place, which is beneficial to the mounting and limiting of the magnet. In addition, the dimensions of the second portion 122 and the magnet can be made as thin as possible while ensuring the secure retention of the magnet. It is understood that the magnetic poles of the magnet are oriented in the X-axis direction, for example, the + X side magnetic pole of the magnet is positive and the-X side magnetic pole is negative.

The support member 30 is used to support and allow the shutter 10 to move in a direction parallel to the X-axis and is made of a lightweight plastic material which is integrally formed. The support member 30 may comprise a base plate and a plurality of linear or vertical springs for suspending the shield 10 on the base plate, the lower ends of the linear or vertical springs being fixed to the base plate and the upper ends of the linear or vertical springs being connected to the shield plate 11. The supporting member 30 may be a plate spring disposed above a base plate, the inner side of the plate spring is connected to the shielding plate 11, and the outer side of the plate spring is connected to a fixing portion erected on the base plate. The supporting member 30 may be two long rails mounted on a substrate, and the two long sides of the shielding sheet 11 contact with the rails.

In this embodiment, the support 30 is substantially rectangular box-shaped, and has an open top, and the inner space is divided into two receiving spaces 31, 32 for receiving the coil 40 and the locking assembly 50, respectively. The upper portions of the two opposite side walls 33 of the support member 30 form a rail for supporting the shutter 11, which is capable of limiting the distance between the shutter 11 and the coil 40 and guiding the shutter 11 to move in a direction parallel to the X-axis. For this purpose, the upper portions of the side walls 33, 34 form L-shaped steps, and a plurality of arc-shaped protrusions 331 are preferably disposed on the steps to reduce the contact area between the shielding plate 11 and the supporting member 30, reduce the friction between the two, and make the sliding of the shielding plate 11 smoother and less resistant. In addition, the width of the light shielding portion 114 of the shielding sheet 11 in the Y-axis direction is larger than the width of the other portions of the shielding sheet 11, so that only both sides of the lower surface of the light shielding portion 114 contact the step of the side wall 33, further reducing the contact area between the shielding sheet 11 and the support 30.

The coil 40 is fixed in the housing space 31 near one end of the housing space 31. In order to prevent the shutter 10 from moving toward the + Z axis side and to limit the moving position of the shutter 10, a magnetic substance, such as a magnetic conductive member 60 made of iron or cobalt or nickel, is further provided between the coil 40 and the bottom of the housing space 31. In this embodiment, the magnetic conductive element 60 includes a substrate 61 having a substantially rectangular plate shape, and stopper portions 62 and 63 extending substantially perpendicularly from both ends of the substrate 61. The substrate 61 is substantially parallel to a plane defined by the X-axis and the Y-axis, has a length greater than the length of the coil 40 in the X-axis, and is greater than or equal to a predetermined moving distance of the light shielding portion 114. Therefore, in the process of moving the magnet 20, magnetic attraction force is generated with the substrate 61 all the time, and the stability of the movement is ensured.

The top ends of the stoppers 62 and 63 should be located on the moving track of the magnet 20 and at two positions where the magnet 20 is supposed to stay. Thus, when the magnet 20 approaches the stoppers 62 and 63, a strong magnetic attraction force can be received. In the present embodiment, the coil 40 is disposed on the substrate 61 with one end portion near one end portion of the substrate 61 and the other end portion near the middle portion of the substrate 61. The position-limiting portion 62 includes two opposite first and second flaps 621 and 622 extending substantially perpendicularly from the other end of the base sheet 61. The first and second flaps 621 and 622 extend from two sides of the base sheet, respectively, and when the magnet 20 moves from the side of the coil to a direction away from the coil by properly setting the current flowing through the coil, the magnet stops due to the magnetic attraction when moving between the first and second flaps 621 and 622 and is limited between the first and second flaps 621 and 622, defining that the light shielding portion 114 is located at the light shielding position (the shielding member is located at the shielding position). The position-limiting portion 63 is a third flap extending substantially perpendicularly from one end of the substrate 61, and is opposite to the end of the coil 40, so that when the magnet 20 moves from the position-limiting portion 62 to the inner side of the coil, it is easily attracted by the position-limiting portion 63 and moves toward the end of the coil 40, and stays at the position-limiting portion 63, defining that the light-shielding portion 114 is located at the exposure position (the shielding member is located at the exposure position), that is, the non-shielding position.

Further, the width (dimension in the Y-axis direction) of the portion of the substrate 61 near the stopper portion 63 is smaller than the width of the portion of the substrate near the stopper portion 62. I.e. the part of the substrate 61 located below the coil 40 is wider and the part not covered by the coil 40 is narrower. With this arrangement, when the magnet moves from the stopper 63 toward the stopper 62, the attraction force of the magnetic conductive element 60 to the magnet 20 is weak, and the friction force when the shutter 10 moves can be reduced, thereby increasing the moving speed.

In this embodiment, the magnetic conductive element 60 is fixed at the bottom of the accommodating space 31 by a fastener, such as a screw. The coil 40 is adhered to the upper surface of the magnetic conductive member 60. A circuit board 42 electrically connected to the coil 40 is further fixed on an outer surface of the sidewall 33 of the accommodating space 31, and a control circuit of the electronic device can control the magnet 20 to drive the shielding member 10 to move between the exposure position and the shielding position by supplying power to the coil 40 through the circuit board 42. Preferably, the magnet 20 is not in contact with the coil 40.

Referring to fig. 5 and 6 together, the locking assembly 50 is used to lock the shutter 10 in the shielding position or the exposing position, so that the locking assembly 50 can hold the shutter 10 in place even if the electronic device suddenly moves at a high speed that may cause the shutter 10 to move out of the shielding position or the exposing position. In this embodiment, the locking assembly 50 mainly includes a second coil 51 wound in a hollow cylindrical shape, a second fixed block 52 disposed between the second coil and the shielding piece 11, a second magnet 53 fixed on the second fixed block 52, and a fixed piece 54 disposed between the shielding piece 11 and the second fixed block 52.

The winding axis of the second coil 51 is parallel to the Z axis and fixed at the middle position of the bottom of the receiving space 32 of the support 30. The fixing piece 54 is made of a magnetic material and serves as a magnetic conduction piece of the locking assembly 50 and is fixed at the opening of the accommodating space 32, i.e., at the upper portions of the two opposite side walls 33 of the supporting member 30. The fixing piece 54 is formed with a hole 541.

The second fixing block 52 is used as a locking part of the locking assembly 50 and is made of a light plastic material by integral molding. The second fixing block 52 includes a cylindrical body 521 and two stopper arms 522 extending from an outer sidewall of the body 521. One end of the body 521 serves as a lock pin 5211, and the other end surface thereof is formed with a hole 5212 for receiving the second magnet 53. Due to the fixing piece 54, when there is no current flowing in the second coil 51, the second magnet 53 and the fixing piece 54 attract each other, and the locking pin 5211 protrudes through the hole 541 in the fixing piece 54 and is inserted into the hole 116 or 117 of the light shielding portion 114, thereby limiting the shutter 10 in the exposure position or the shielding position. When a current of a first predetermined direction flows through the second coil 51, the magnetic field generated drives the second magnet 53 to move to the-Z axis side in the inner peripheral side of the second coil 51, so that the locking pin 5211 is disengaged from the hole 116 or 117, and the coil 40 drives the shutter 10 to move. When a current opposite to the first predetermined direction flows through the second coil 51, the magnetic field generated drives the second magnet 53 to move toward the + Z axis side at the inner circumferential side of the second coil 51, so that the locking pin 5211 is inserted into the hole 116 or 117 again, locking the shutter 10. It is understood that when the magnetic field of the second magnet 53 is strong enough, or the stator 54 is also a permanent magnet, the current opposite to the first predetermined direction may be cancelled, and when the current in the first predetermined direction is stopped being supplied to the second coil 51, the second magnet 53 may drive the second fixing block 52 to automatically reset.

In this embodiment, a circuit board 55 electrically connected to the second coil 51 is further fixed on an outer surface of the sidewall 33 of the accommodating space 32, and a control circuit of the electronic device can control the second magnet 53 to move by supplying power to the second coil 51 through the circuit board 55.

The stopper arm 522 serves to prevent the second fixing block 52 from rotating and tilting when the second fixing block 52 moves in the Z-axis direction. Specifically, in the present embodiment, the position-limiting arm 522 is substantially L-shaped, and a first portion 5221 thereof extends substantially perpendicularly from the outer sidewall of the body 521, and a second portion 5222 thereof extends from the end of the first portion 5221 toward the bottom, i.e., the-Z-axis side, of the accommodating space 32. Correspondingly, two retaining grooves 321 for inserting the second portions 5222 of the retaining arms 522 are formed in the accommodating space 32.

In addition, a limit stage 523 extends from the outer side wall of the body 521 substantially vertically, the upper surface of the limit stage 523 is substantially flush with the upper surface of the first portion 5221, and when the second fixing block 52 moves to the highest position, that is, abuts against the fixing plate 54, the number of the positions where the second fixing block 52 contacts the fixing plate 54 is three, which is more stable.

To further prevent the shield 10 from being detached from the support member 30, the shielding device of the present invention further includes a protective cover 70. The protective cap 70 is fixedly connected to the support member 30 and is immovable relative to the support member, so as to clamp the shield 10 between the protective cap 70 and the support member 30. The protective cover 70 is also made of a light plastic material by integral molding. In the electronic apparatus, the support 30 of the shielding device is placed side by side with the image pickup device, and the length of the protective cover 70 is longer than that of the support 30. The protective cover 70 further covers the image pickup device, and a through hole 71 for exposing a lens of the image pickup device is formed at a position where it does not cover the support member 30. The free end of the protective cover 70 also forms a bent portion 72 for enclosing the side of the camera device, so that the camera device and the shielding device can be connected more tightly. The light shielding portion 114 of the shielding plate 11 of the shielding member 10 does not protrude beyond the end of the supporting member 30 in the exposure position, so that the lens is exposed, and when the image pickup device is activated, an image outside the electronic apparatus can be captured. When the shielding member 10 is located at the shielding position, the light shielding portion 114 extends out of the end of the supporting member 30 to shield the lens, and at this time, even if the image capturing device is turned on, an image outside the electronic device cannot be captured, so that privacy is well protected.

In operation, to protect privacy, the initial position of the shield 10 should be the shielding position. When the lens of the camera needs to be exposed to enable the camera to capture an image outside the electronic device, the control circuit of the electronic device may send an instruction to the circuit board 55, the circuit board 55 may supply power to the second coil 51 to disengage the locking pin 5211 from the hole 116, then send an instruction to the circuit board 42 to enable the circuit board 42 to supply power to the coil 40, enable the coil 40 to drive the shielding member 10 to move to the exposed position, and finally send an instruction to the circuit board 55, and the circuit board 55 may supply an opposite current to the second coil 51 to enable the locking pin 5211 to be inserted into the hole 117, so as to lock the shielding member 10 at the exposed position. When the shielding member 10 needs to be returned to the shielding position, the control circuit of the electronic device first sends an instruction to the circuit board 55, the circuit board 55 supplies power to the second coil 51, the lock pin 5211 is disengaged from the hole 117, then sends an instruction to the circuit board 42, the circuit board 42 supplies power to the coil 40, the coil 40 drives the shielding member 10 to move to the shielding position, and finally sends an instruction to the circuit board 55, the circuit board 55 supplies opposite current to the second coil 51, the lock pin 5211 is inserted into the hole 116, and the shielding member 10 is locked at the shielding position.

Example two:

referring to fig. 6 to 10, in the shielding apparatus of the electronic device of the second embodiment, a position detecting component 80 is added compared to the shielding apparatus of the first embodiment. The support member 30, the locking assembly 50, the magnetic conductive element 60, the magnet 20, the coil 40 and the circuit board 42 in the present embodiment are the same as those in the first embodiment, and the same reference numerals are used. For convenience of understanding, the components in the second embodiment are the same as those in the first embodiment, and the same reference numerals are used for the components in the first embodiment.

In contrast to the shutter 10 of the first embodiment, the shutter 10 'of the present embodiment extends from the second end 112 in the + X-axis direction, and sequentially forms an exposed portion 118 having an opening 1181, a third fixing portion 119 for fixing components of the position detection unit 80, and a third end 120 of the shutter 10'. The imaging device of the electronic apparatus is fixed behind the exposure portion 118, and the lens faces the opening 1181 of the exposure portion 118. The third fixing portion 119 includes a protrusion 1191 extending from the shielding plate 11 toward the-Z axis side, a groove 1192 opened toward the-Z axis side is formed in the protrusion 1191, and a column 1193 extends from the end of the top of the protrusion 1191 close to the protrusion toward the-Z axis side. The third end 120 is also formed with a recess 1201 on the side facing the protective cover 70' for securing an opaque or translucent film or foil 1202.

Correspondingly, the protective cover 70' is correspondingly extended to cover the position detecting member 80, specifically, the portion between the bent portion 72 and the through hole 71 is extended. An opening 73 is also formed in the protective cover 70' near the distal end. When the shielding member 10' is located at the shielding position, the groove 1201 with the opaque or semi-opaque film or sheet 1202 fixed thereon is opposite to the opening 73, so as to cover the opening 73, and an image pickup device is also arranged behind the opening 73, that is, the electronic apparatus of the embodiment has two image pickup devices.

In this embodiment, the position detecting assembly 80 is used to detect the position of the shutter 10', and includes a third magnet 81 fixed in a groove 1192 of the third fixing portion 119 of the shutter 10', a second supporting member 82, a circuit board 83 fixed on the second supporting member 82, and a hall element 84 fixed on the circuit board 83. The second supporting member 82 is a box-shaped member having a receiving groove 821, and is preferably made of a light plastic material by integral molding.

The circuit board 83 is fixed to the inner side wall or the outer side wall of the second support 82, in this embodiment, the outer side wall, that is, the circuit board 83 is fixed to the outer side wall of the second support 82 in a manner substantially parallel to the Z-axis. Thus, the connection between the circuit board 83 and an external circuit is facilitated, and the circuit board 83 is easier to operate when assembled. Preferably, the third magnet 81 and the hall element 84 are opposed in a plane defined substantially parallel to the X axis and the Y axis, so that the position detection can be more accurate. In the present embodiment, when the shutter 10 is in the shielding position, the third magnet 81 and the hall element 84 face each other in the Y-axis direction. In addition, a clearance is formed on a side wall of the second support 82 so that the hall element 84 protrudes into the accommodation groove 821. It is also possible to expose a portion of the third magnet 81 from the notch of the protrusion 1191, so that the hall element 84 can more easily sense the magnetic field of the third magnet 81.

In this embodiment, the accommodating groove 821 is provided with a gel 85 for absorbing shock. The ends of the posts 1193 are in constant contact with the gel 85 during movement of the shield 10' and absorb shock transmitted from the shield 10', thereby reducing the sound of movement of the shield 10 '.

In operation, when the shutter 10 'is in the shutter position, the hall element 84 is spaced from and opposed to the third magnet 81, and when the shutter 10' is moved to the exposure position, the third magnet 81 is moved to a position not directly opposed to the hall element 84. The control circuit of the electronic device can determine the position of the shutter 10' according to the variation of the magnetic field strength detected by the hall element 84, thus assisting the on-off control of the shutter means. For example, but not limited to, after each shutter movement is controlled, before the locking assembly 50 is controlled to be locked, the position detection assembly 80 is used to detect whether the shutter 10 'reaches the preset position, and the locking assembly 50 is controlled to be locked only when the shutter 10' reaches the preset position, so that the product control is more precise. In addition, the function of the shielding apparatus may be verified by using the position detecting assembly 80, for example, after the shielding member 10' is controlled to move and the locking assembly 50 is controlled to be locked, the specific position of the shielding member 10' is detected, so as to determine whether the movement control of the shielding member 10' is accurate, whether the locking assembly 50 can normally operate, and the like.

In this embodiment, the third magnet 81 is fixed in the slot 1192 of the protrusion 1191 of the shielding plate 11, and it can be understood that in other embodiments, the third magnet may be directly adhered to the surface of the shielding plate 11 on the-Z axis side.

Example three:

referring to fig. 11, the present embodiment is different from the first embodiment in that a locking mechanism is eliminated. The shielding device of the embodiment is suitable for electronic equipment with large size (relative to a smart phone) such as a notebook computer, a desktop computer, a display and the like, which is not moved frequently or even moved frequently.

Example four:

the present embodiment is similar to the second embodiment in that two image capturing devices are separated by the position detecting assembly 80, and the fourth embodiment in that two image capturing devices are closely arranged together or integrated, so that the through holes 71 and 73 of the protective cover 70 are adjacently arranged or combined into a rectangular through hole. Correspondingly, the light shielding portion 114 and the exposed portion 118 of the shutter 10' are longer in size, and the third end 120 is shorter.

In a variation of the above embodiment, the apertures 116 and 117 in the blinders 10, 10' may be replaced by slots or indentations.

In the above embodiments, the through holes 71, 73 of the protective covers 70, 70 'and the openings 1181 of the shutters 10, 10' may be replaced by notches extending through the edges of the protective covers 70, 70 'and the shutters 10, 10'.

In the above embodiment, the magnetic conductive member 60 is used to restrict the movement of the shutters 10 and 10' in the Z-axis direction and the X-axis direction. In other embodiments, the magnetic permeable element 60 may be omitted. Because the utility model discloses a shelter from the magnetic force that four limits of device make full use of coil produced, magnet collocation coil can drive shielding piece well and remove along X axle direction.

In the second and fourth embodiments, the gel 85 is disposed in the receiving groove 821 of the second supporting member 82, and the column 1193 for inserting the gel 85 is formed on the shielding member 10'. In other embodiments, the gel and column may be omitted.
