Next, referring to fig. 1 to 3, fig. 2 is a schematic perspective view of a shielding module 200 according to an embodiment of the invention, and fig. 3 is a schematic cross-sectional view of the shielding module 200, a camera module 106 and a front cover 1041 according to an embodiment of the invention. As shown in fig. 1, the electronic device 100 may further include a shielding module 200, the shielding module 200 is detachably disposed on the front cover plate 1041, that is, the front cover plate 1041 is disposed between the camera module 106 and the shielding module 200, and the shielding module 200 is configured to shield a lens of the camera module 106, so as to prevent a hacker from invading the electronic device 100 through a network and using the camera module 106 to peep the operation and other behaviors of the user.
As shown in fig. 2 and fig. 3, the shielding module 200 may have a base 202, a moving member 204, and a first conductive element 206. The base 202 may be formed with a sliding groove 2021, such that the moving member 204 can move along the sliding groove 2021 relative to the base 202 and the camera module 106, for example, along the X-axis direction. As shown in fig. 3, the moving member 204 may have a first end portion 2041, a connecting portion 2043 and a second end portion 2045. The connecting portion 2043 connects the first end portion 2041 and the second end portion 2045, and the bottom of the moving member 204 of the first conductive element 206 is disposed at the bottom of the second end portion 2045.
In some embodiments of the present invention, the moving member 204 can be made of plastic or other non-conductive material, and the first conductive element 206 can be made of conductive material. For example, the first conductive element 206 may be made of silver, aluminum, platinum, copper material, but is not limited thereto. In addition, the first conductive element 206 can also be a conductive cloth or a conductive tape. Furthermore, it is noted that the shielding module 200 may have a thickness H1 along the Z-axis direction, and in this embodiment, the thickness H1 may be 2mm or less than 2mm, so as to facilitate the user to mount the shielding module 200 on the front cover plate 1041.
As shown in fig. 3, the shielding module 200 is disposed on the front cover plate 1041 (for example, but not limited to, it may be disposed by using an adhesive), and the front cover plate 1041 may be made of a plastic material and has a through hole 1045. In addition, the base 202 may further have an opening 2023, which is connected to the chute 2021 and the through hole 1045. In addition, the camera module 106 may have a circuit board 1061 and a lens 1063 disposed on the circuit board 1061. As shown in fig. 3, the lens 1063 is aligned between the through hole 1045 and the opening 2023, so that the lens 1063 can receive light passing through the opening 2023 and the through hole 1045 to perform functions of shooting or video recording.
As shown in fig. 3, the first capacitance sensing element 108 is disposed on the inner side of the front cover 1041, and is located at the first capacitance sensing element 108 when the moving element 204 is located at the rightmost position (which may be defined as a first position) of the base 202. In this embodiment, the first capacitive sensing element 108 is disposed on a Flexible Printed Circuit (FPC) 109. For example, the flexible circuit board 109 is disposed on the inner side of the front cover 1041 and electrically connected to the monitoring circuit 1021, so that the monitoring circuit 1021 can receive a signal of the first capacitance sensing element 108 on the flexible circuit board 109.
When the moving element 204 is at the first position, the first capacitive sensing element 108 senses the first conductive element 206 to generate a sensing signal, and the sensing signal can be used as an enabling signal (e.g., a low level signal in the digital signal). The monitor circuit 1021 then enables the camera module 106 according to the enable signal, such as providing power to the camera module 106. In addition, the monitor circuit 1021 may also execute an application program, such as a camera program or a video recording program, stored in the storage circuit 1023 according to the enable signal.
Referring to fig. 3 and fig. 4, fig. 4 is a schematic cross-sectional view of the moving element 204 shown in fig. 3 after moving. When the moving member 204 is driven by the force to move from the rightmost position of the base 202 to the position shown in fig. 4, the moving member 204 is located at the leftmost position (which may be defined as the second position) of the base 202, and at this time, the moving member 204 completely covers the opening 2023 and the lens 1063 of the camera module 106. At this time, since the first conductive element 206 is separated from the top of the first capacitive sensing element 108, the first capacitive sensing element 108 does not sense the first conductive element 206 and the sensing signal changes (for example, a low level signal in the digital signal changes into a high level signal). Therefore, the monitor circuit 1021 can determine that the moving part 204 has covered the camera module 106 according to the sensing signal, and then the monitor circuit 1021 can stop supplying power to the camera module 106 to turn off the camera module 106. In addition, when the moving element 204 is located at the second position, the monitoring circuit 1021 may also close the aforementioned photographing procedure or video recording procedure.
As can be seen from the above description, in order to prevent a hacker from invading the electronic device 100 through a network and using the camera module 106 to peep the user's operation and other behaviors, the user can directly attach the shielding module 200 with a very thin thickness to the front cover 1041, and move the moving member 204 to shield or expose the camera module 106, so as to close or activate the camera module 106.
Referring to fig. 5 again, fig. 5 is a schematic cross-sectional view of the shielding module 200, the camera module 106 and the front cover 1041 according to another embodiment of the invention. The structure of this embodiment is similar to that of the previous embodiment, and the difference is that the first capacitive sensing element 108 of this embodiment can be integrated with the camera module 106, for example, disposed on the circuit board 1061, and electrically connected to the monitoring circuit 1021 through the circuit of the circuit board 1061. Therefore, in the embodiment, no additional flexible circuit board is required, which not only saves the manufacturing cost of the electronic device 100, but also simplifies the manufacturing process of the electronic device 100. It is noted that the first capacitive sensing element 108 may be disposed on the circuit board 1061 or the front cover 1041 according to actual design requirements. In addition, the operations of the shielding module 200 and the monitoring circuit 1021 in this embodiment are similar to those in the previous embodiments, and are not repeated herein.
Referring to fig. 6, fig. 6 is a schematic cross-sectional view of a shielding module 200A, a camera module 106 and a front cover 1041A according to another embodiment of the invention. In this embodiment, the front cover 1041A may be made of glass, and the base 202A of the shielding module 200A may have a slot 2025. As shown in fig. 6, the slot 2025 penetrates the bottom of the base 202A, and the moving member 204 moves along the slot 2025 relative to the base 202A and the camera module 106. In this embodiment, the first conductive element 206 is located between the moving element 204 and the front cover 1041A. More specifically, the first conductive element 206 is located at the bottom of the second end 2045 of the moving member 204 and contacts the front cover 1041A. However, in other embodiments, the first conductive element 206 may not contact the front cover 1041A.
In addition, in this embodiment, the first capacitive sensing element 108 is disposed on the circuit board 1061 of the camera module 106 to be electrically connected to the monitoring circuit 1021, but is not limited thereto. For example, in other embodiments, the first capacitive sensing element 108 may also be disposed on a flexible circuit board as in the embodiment of fig. 3, and the flexible circuit board is attached to the inner side of the front cover plate 1041A. The position of the first capacitive sensing element 108 may be determined according to actual design requirements.
Referring to fig. 7, fig. 7 is a schematic cross-sectional view of a shielding module 200A, a camera module 106 and a front cover 1041A according to another embodiment of the invention. This embodiment is similar to the embodiment of fig. 6, and the electronic device in this embodiment may further include a conductive layer 110 disposed on the inner side of the front cover plate 1041A. In this embodiment, the front cover 1041A may be a top glass layer of a touch panel, and the conductive layer 110 may be included in a touch layer of the touch panel, disposed on an inner side of the front cover 1041A and electrically connected to the monitoring circuit 1021. The touch panel may be a GFF, GF, OGS, GG, OGM, GMM, or the like, and the conductive layer 110 may be any one of the touch layers in the aforementioned common structure.
As shown in fig. 7, the first capacitive sensing element 108 may be formed on the conductive layer 110 and configured to sense the first conductive element 206. It is noted that, since the first capacitive sensing element 108 of this embodiment can be formed on the conductive layer 110, for example, the first capacitive sensing element 108 is directly formed on the conductive layer 110 when the display screen 105 and the front cover 1041A are manufactured. Therefore, the design of this embodiment does not require additional circuit boards, which not only saves the manufacturing cost of the electronic device 100, but also simplifies the manufacturing process of the electronic device 100.
Referring to fig. 8A, fig. 8A is a top view of the base, the first capacitive sensing element 108 and a second capacitive sensing element 112 according to some embodiments of the invention. In this embodiment, the base is base 202A, but could also be base 202. For clarity, the moving element 204 and the first conductive element 206 are omitted in fig. 8A and 8B.
As shown in fig. 8A, the first capacitive sensing element 108 is disposed at the bottom right side of the base 202A (corresponding to the first position). Furthermore, the electronic device may further include a second capacitive sensing element 112 disposed below the base 202A along the Z-axis. The shielding module 200A further has a second conductive element 208 corresponding to the second capacitance sensing element 112 and disposed at the bottom of the base 202A. In this embodiment, the second conductive element 208 has a rectangular structure and is disposed on a long side of the base 202A, and the second capacitive sensing element 112 also has a rectangular structure corresponding to the second conductive element 208. In this embodiment, the first capacitive sensing element 108 and the second capacitive sensing element 112 are electrically connected to the monitoring circuit 1021 through a conducting wire WR.
In this embodiment, the second capacitive sensing element 112 is configured to sense the second conductive element 208 and output a sensing value, and the monitoring circuit 1021 can receive and monitor the sensing value to determine whether the second capacitive sensing element 112 is aligned with the second conductive element 208. For example, the monitoring circuit 1021 may compare the sensed value with a predetermined threshold, and if the sensed value is greater than the predetermined threshold, the monitoring circuit 1021 may determine that the second conductive element 208 is located on the second capacitive sensing element 112. That is, the pair of occlusion modules 200A is located at the camera module 106. On the other hand, if the sensing value is smaller than the predetermined threshold, the monitoring circuit 1021 can determine that the second capacitive sensing element 112 is not aligned with the second conductive element 208.
When the monitoring circuit 1021 determines that the second conductive element 208 is not aligned with the second capacitive sensing element 112, i.e., the shielding module 200A is not aligned with the camera module 106, the monitoring circuit 1021 may control the display screen 105 to display a reminding message, such as a dialog window, thereby reminding the user to mount the shielding module 200A on the front cover 1041 and align with the camera module 106 again.
Referring to fig. 8B to 8D, fig. 8B to 8D are top views of a base, a first capacitive sensing element 108 and a second capacitive sensing element 112 according to other embodiments of the present invention. As shown in fig. 8B, the second conductive element 208 may have a U-shaped configuration, corresponding to the shape of the base 202A, and the second capacitive sensing element 112 may also have a corresponding U-shaped configuration.
In addition, as shown in fig. 8C and 8D, the bottom of the base 202A may be provided with two second conductive elements 208, and the electronic device 100 may be correspondingly provided with two second capacitive sensing elements 112. In the embodiment of fig. 8C, two second conductive elements 208 are disposed on two short sides of the base 202A, and two second capacitive sensing elements 112 are correspondingly disposed below the two second conductive elements 208 along the Z-axis direction, respectively. In the embodiment shown in fig. 8D, two second conductive elements 208 are disposed on two long sides of the base 202A, and two second capacitive sensing elements 112 are correspondingly disposed below the two second conductive elements 208 along the Z-axis direction, respectively.
Through the design in the embodiments of fig. 8B to 8D, the accuracy of the monitoring circuit 1021 in determining whether the base 202A is located in the camera module 106 can be improved.
Referring to fig. 9, fig. 9 is a flowchart of a method for switching the camera module 106 according to some embodiments of the invention. In step S100, a shielding module is disposed above the camera module 106 of the electronic device 100. In step S102, when the shielding module is disposed on the camera module 106, a second conductive element 208 on the shielding module 200 is sensed by a second capacitive sensing element 112 to output a sensing value. In step S104, the monitoring circuit 1021 determines whether the blocking module is located in the camera module 106 according to the sensing value, for example, the monitoring circuit 1021 compares the sensing value with a predetermined threshold. When the sensing value is greater than the predetermined threshold, the monitoring circuit 1021 determines that the shielding module 200 is located in the camera module 106, and then executes step S106. When the sensing value is smaller than the predetermined threshold, the monitoring circuit 1021 determines that the shielding module 200 is not aligned with the camera module 106, and then executes step S114.
In step S106, a first conductive element 206 on the moving element 204 of the shielding module 200 is sensed by a first capacitive sensing element 108 to generate a sensing signal. Next, in step S108, the monitoring circuit 1021 determines whether the moving element 204 is located at a first position according to the sensing signal. If the moving member 204 is located at the first position, step S110 is executed. If the moving member 204 is located at a second position, not the first position, step S112 is executed.
In step S110, when the moving member 204 is located at the first position, the electronic device 100 provides power to the camera module 106 to activate the camera module 106. In step S112, when the moving element 204 is not at the first position but at the second position, the electronic device 100 stops supplying power to turn off the camera module 106, and the moving element 204 shields a lens 1063 of the camera module 106.
In step S114, when the monitoring circuit 1021 determines that the shielding module 200 is not aligned with the camera module, the monitoring circuit 1021 controls a display screen 105 of the electronic device 100 to send out a reminding message.
Compared with the prior art, the present invention provides an electronic device 100 having a detachable shielding module, so that a user can mount the shielding module 200 on the camera module 106 of the electronic device 100. The monitoring circuit 1021 can determine whether the moving element 204 of the shielding module 200 shields the lens 1063 of the camera module 106 according to the sensing signal output by the first capacitive sensing element 108 sensing the first conductive element 206, so as to determine whether to provide power to turn on the camera module 106 or stop supplying power to turn off the camera module 106.
Furthermore, the monitoring circuit 1021 can further determine whether the shielding module 200 is aligned with the camera module 106 according to the sensing value output by the second conductive element 208 sensed by the second capacitive sensing element 112. When the shielding module 200 is not aligned with the camera module 106, the monitoring circuit 1021 may control the display screen 105 of the electronic device 100 to send out a warning message to notify the user to reinstall the shielding module to align with the camera module 106, so that the monitoring circuit 1021 can monitor the position of the moving element 204 more accurately.
Therefore, the electronic device 100 with the shielding module not only can solve the problem of hacking and peeping, but also has the advantage of power saving. In addition, since the first capacitive sensing element 108 and the second capacitive sensing element 112 can be formed on the touch layer together during the production of the touch panel, the advantages of saving the manufacturing cost and reducing the process steps can also be achieved.
