[0064] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0065] The present application embodiment provides a camera module, such as Figure 1 and Figure 2 As shown, the camera module includes a camera body 1, a driving component 2 and a shading member 3. The driving component 2 is connected to the shading member 3, and the driving component 2 is configured to drive the shading member 3 to move so that the shading member 3 shields or exposes the light-incoming area 11 of the camera body 1. The moving direction of the shading member 3 is perpendicular to the orientation direction of the camera body 1.

[0066] In the camera module provided in the embodiment of the present application, when the driving component 2 drives the shading member 3 to move in a direction perpendicular to the direction of the camera body 1 to shield the light input area 11 of the camera body 1, the light input area 11 cannot receive external ambient light because it is shielded by the shading member 3, thereby achieving physical shielding of the camera through the shading member 3.

[0067] In addition, the camera module provided in the embodiment of the present application can conveniently achieve physical shielding of the camera by driving the shading member 3 to move through the driving component 2, thereby improving the user experience.

[0068] In the embodiment of the present application, the light inlet area 11 can be understood as the area where the lens of the camera body 1 is located. The camera body 1 can receive external ambient light through the light inlet area 11 to achieve an imaging function. In some embodiments, the orientation direction of the camera body 1 can be parallel to the optical axis of the camera body 1.

[0069] Alternatively, if Figure 1 As shown, the camera module may further include a mounting member 4, and the driving assembly 2 may be connected to the mounting member 4, so that the driving assembly 2 and the mounting member 4 are integrated together. The mounting member 4 may have an avoidance hole 41, and at least a portion of the camera body 1 is exposed through the avoidance hole 41. The shading member 3 may be located on the exposed side of the camera body 1.

[0070] In some embodiments, the light entrance area 11 of the camera body 1 is exposed relative to the avoidance hole 41 , so that the light shielding member 3 located on the exposed side of the camera body 1 can shield or expose the light entrance area 11 when moving.

[0071] like Figure 1 As shown, by providing an avoidance hole 41 on the mounting member 4, the mounting member 4 can be looped around the camera body 1, thereby avoiding significantly increasing the thickness of the camera module in the optical axis direction of the camera body 1, and further avoiding significantly increasing the thickness of the electronic device when the camera module is assembled into the electronic device.

[0072] In some embodiments, the shading member 3 may be made of a light-proof material, so that when the shading member 3 shields the light-entering area 11, the light-entering area 11 may be blocked from receiving ambient light. Exemplarily, the shading member 3 may be made of a black light-shielding material, so that when the camera module is integrated into an electronic device, the shading member 3 is invisible to the user when the display screen of the electronic device is turned off.

[0073] Alternatively, if Figure 1 and Figure 2As shown, the driving assembly 2 includes a driving member 21 and a guiding member 22, wherein the driving member 21 is connected to the mounting member 4; the guiding member 22 is connected to the driving member 21 and the shading member 3 respectively, and the guiding member 22 is configured to drive the shading member 3 to move along the extension direction of the guiding member 22 under the drive of the driving member 21.

[0074] In some embodiments, the guide member 22 may be a guide rod, the shading member 3 may have a first through hole, and the guide rod may be inserted into the first through hole to achieve connection between the guide member 22 and the shading member 3 .

[0075] In some embodiments, the driving member 21 may be a rotary motor, and the guide member 22 may be a lead screw. The shading member 3 is movably sleeved on the guide member 22 and threadedly engaged with the guide member 22. That is, the inner wall of the perforation of the shading member 3 may have an internal thread that engages with the thread on the lead screw. When the driving member 21 drives the guide member 22 to rotate, the guide member 22 drives the shading member 3 to move along the extension direction of the guide member 22 through threaded engagement.

[0076] In some embodiments, the driving member 21 may also be a linear motor, and the guide member 22 may be a light rod. The guide member 22 is fixedly sleeved on the guide member 22, so that when the driving member 21 drives the guide member 22 to extend and retract, the guide member 22 can drive the shading member 3 to move together.

[0077] In some embodiments, the driving assembly 2 may further include a support seat 23, which may be arranged opposite to the driving member 21, and opposite ends of the guide member 22 may be respectively connected to the driving member 21 and the support seat 23. The guide member 22 may rotate relative to the support seat 23, or may be able to extend and retract relative to the support seat 23. Exemplarily, the support seat 23 may have a second through hole, and the guide member 22 may extend into the second through hole and may rotate or retract in the second through hole.

[0078] In some embodiments, in order to prevent the shading member 3 from shaking during movement, resulting in inaccurate positioning of the shading member 3, the camera module may specifically include two drive assemblies 2, and the two drive assemblies 2 may be both located on the exposed side of the camera body 1 and symmetrically arranged about the optical axis of the camera body 1. The two ends of the shading member 3 may be connected to a drive assembly 2 respectively.

[0079] Alternatively, if Figure 1 , Figure 2 and Figure 3 As shown, the shading member 3 may include a shading portion 31 and a connecting portion 32 , wherein the shading portion 31 may be configured to shield or expose the light-incoming area 11 of the camera body 1 ; and the connecting portion 32 may be configured to be connected to the driving assembly 2 .

[0080] like Figure 3As shown, the light shielding portion 31 may be a plate-shaped member with uniform thickness, and the light shielding portion 31 may be substantially perpendicular to the optical axis direction of the camera body 1. The width of the light shielding portion 31 is not less than the maximum diameter of the light inlet area 11 or the dimension of the light inlet area 11 in the width direction of the light shielding portion 31, and the width direction of the light shielding portion 31 may be parallel to the extension direction of the guide member 22 in the driving assembly 2.

[0081] Furthermore, the two opposite ends of the light shielding portion 31 along the length direction may each have a connecting portion 32, and the two connecting portions 32 may be connected to the side of the light shielding portion 31 facing the mounting member 4, that is, the two connecting portions 32 may be bent relative to the light shielding portion 31 toward the mounting member 4, thereby providing support for keeping the light shielding portion 31 on the exposed side of the camera body 1. The first through hole in the light shielding member 3 that cooperates with the guide member 22 in the driving assembly 2 may be opened on the connecting portion 32.

[0082] Alternatively, if Figure 1 and Figure 2 As shown, the camera module further includes a positioning member 5, which is connected to the mounting member 4, and the positioning member 5 is configured to trigger a stop signal when detecting that the shading member 3 moves to the shielding position. The stop signal is configured to instruct the driving component 2 to stop driving the shading member 3, wherein when the shading member 3 moves to the shielding position, the light-entry area 11 is shielded.

[0083] In some embodiments, when the light shielding member 3 is in the shielding position, the center of the light entrance area 11 may coincide with the center of the light shielding portion 31 along the width direction, so as to ensure the shielding effect of the light shielding member 3 on the light entrance area 11. In addition, the centers of the light shielding portion 31 and the connecting portion 32 along the extension direction of the guide member 22 may be on the same plane, so as to ensure the supporting effect of the connecting portion 32 on the light shielding portion 31. That is, when the light shielding member 3 is in the shielding position, the center of the light entrance area 11, the center of the light shielding portion 31 along the width direction, and the center of the connecting portion 32 along the extension direction of the guide member 22 are on the same plane.

[0084] In the embodiment of the present application, a positioning member 5 is provided to detect the moving position of the shading member 3, and when it is detected that the shading member 3 moves to a shielding position capable of shielding the light entrance area 11, a signal is automatically triggered to notify the driving component 2 to stop driving the shading member 3, thereby ensuring the accuracy of the stop position of the shading member 3 and further ensuring the shielding effect of the shading member 3 on the light entrance area 11.

[0085] In some embodiments, the positioning member 5 may be disposed at only one end of the shading member 3, for example, only used to detect the position of one connecting portion 32. Alternatively, the positioning member 5 may be disposed at both ends of the shading member 3, and each driving assembly 2 corresponds to a positioning member 5.

[0086] Alternatively, if Figure 1 and Figure 2As shown, the positioning member 5 may include a first position sensor. When the shading member 3 is in the shielding position, the orthographic projection of the first position sensor on the first setting plane may be located within the orthographic projection of the shading member 3 on the first setting plane, and the first setting plane is parallel to the movement plane of the shading member 3.

[0087] In some embodiments, the first position sensor may be disposed on the surface of the mounting member 4 facing the shading member 3, and the first position sensor may be disposed near the shielding position of the shading member 3. When the shading member 3 moves to the shielding position, the first position sensor may detect a position signal of the shading member 3, and determine based on the position signal that the shading member 3 has moved to the shielding position, thereby sending a stop signal to the driving assembly 2 to instruct the driving assembly 2 to stop driving the shading member 3.

[0088] In some embodiments, the setting position of the first position sensor can be determined according to the size of the connecting portion 32 along the extending direction of the guide member 22. For example, the first position sensor can be set at a position offset from the shielding position to the driving member 21 by half the width of the connecting portion 32 (the size along the extending direction of the guide member 22), so that when the edge of the connecting portion 32 close to the driving member 21 is detected by the first position sensor, the first position sensor can determine that the shading member 3 moves to the shielding position.

[0089] In other embodiments, the first position sensor may be disposed at the shielding position of the shading member 3, and the positioning member 5 may further include a sensing sheet, which may be attached to the center position of the connecting portion 32 along the extending direction of the guide member 22. When the first position sensor detects the sensing sheet, it can be determined that the shading member 3 moves to the shielding position.

[0090] Alternatively, if Figure 3 , Figure 4 and Figure 5 As shown, the positioning member 5 includes a first conductive sheet 51 and a second conductive sheet 52, wherein the first conductive sheet 51 is connected to the mounting member 4, and the second conductive sheet 52 is connected to the shading member 3. When the shading member 3 moves to the shielding position, the first conductive sheet 51 and the second conductive sheet 52 are in contact and electrically connected to trigger a stop signal.

[0091] In some embodiments, the first conductive sheet 51 can be arranged at a shielding position on the mounting member 4, and the second conductive sheet 52 can be arranged at a central position of the connecting portion 32 in the light shielding member 3 along the extension direction of the guide member 22, so that when the light shielding member 3 moves to the shielding position, the first conductive sheet 51 and the second conductive sheet 52 are in contact and electrically connected. The moving position of the light shielding member 3 is detected by two conductive sheets respectively arranged on the mounting member 4 and the light shielding member 3, which has a simple structure and low cost, and helps to reduce the thickness of the camera module in the optical axis direction of the camera body 1.

[0092] The first conductive sheet 51 may be electrically connected to the driving member 21. Figure 1 and Figure 2 As shown, the mounting member 4 may be provided with a groove, and a third conductive sheet may be provided in the groove. A fourth conductive sheet may be provided at the bottom of the side where the driving member 21 is connected to the mounting member 4. When the driving member 21 is assembled to the mounting member 4, the third conductive sheet contacts and is electrically connected with the fourth conductive sheet, thereby supplying power to the driving member 21.

[0093] In some embodiments, the first conductive sheet 51 can be connected to the signal input interface of the driving member 21. When the first conductive sheet 51 and the second conductive sheet 52 are in contact and electrically connected, the driving member 21 can detect the generated electrical signal and stop driving the shading member 3 to move.

[0094] In some embodiments, the mounting member 4 itself may be an active element. Alternatively, the mounting member 4 may be a passive element, and the mounting member 4 may have a via hole, through which the first conductive sheet 51 or the driving member 21 may be connected to an external circuit as well as other conductive elements.

[0095] In some embodiments, when the driving member 21 and the supporting base 23 are fixed on the mounting member 4, they need to be fixed with non-magnetic screws to avoid signal interference.

[0096] Alternatively, if Figure 5 As shown, the camera module further includes a second position sensor 6, which is connected to the mounting member 4. When the shading member 3 is located at the exposed position, the orthographic projection of the second position sensor 6 on the second setting plane is located within the orthographic projection of the shading member 3 on the second setting plane, the second setting plane is parallel to the movement plane of the shading member 3, and when the shading member 3 is located at the exposed position, the light inlet area 11 is exposed.

[0097] In some embodiments, the first setting plane and the second setting plane may be the same plane, or may be two different planes parallel to each other.

[0098] like Figure 6 As shown, when the shading member 3 is in the exposed position, the shading member 3 avoids the field of view of the camera body 1, that is, the shading member 3 does not block the field of view of the camera body 1. The second position sensor 6 is used to detect whether the shading member 3 moves to the exposed position where the light inlet area 11 can be exposed, thereby ensuring the accuracy of the stop position of the shading member 3, and further ensuring that the shading member 3 does not affect the field of view of the camera body 1 when the user needs to use the camera.

[0099] In some embodiments, the second position sensor may be disposed on the surface of the mounting member 4 facing the shading member 3, and the second position sensor may be disposed near the exposed position of the shading member 3. When the shading member 3 moves to the exposed position, the second position sensor may detect a position signal of the shading member 3, and determine based on the position signal that the shading member 3 has moved to the exposed position, thereby sending a stop signal to the driving assembly 2 to instruct the driving assembly 2 to stop driving the shading member 3.

[0100] In some embodiments, the setting position of the second position sensor can be determined according to the size of the connecting portion 32 along the extension direction of the guide member 22. For example, the second position sensor can be set at a position offset from the exposed position to the support seat 23 by half the width of the support seat 23 (the size along the extension direction of the guide member 22), so that when the edge of the connecting portion 32 close to one side of the support seat 23 is detected by the second position sensor, the second position sensor can determine that the light shielding member 3 moves to the exposed position.

[0101] In other embodiments, the second position sensor may be disposed at the exposed position of the light shielding member 3. When the first position sensor detects the sensing sheet attached to the connecting portion 32, it may be determined that the light shielding member 3 moves to the exposed position.

[0102] In some embodiments, the second position sensor may not be provided on the mounting member 4. The reverse (extension) time of the driving member 21 moving from the shielding position to the exposure position is controlled to be equal to the forward (retraction) time of the driving member 21 moving from the exposure position to the shielding position, so as to determine that the driving member 21 drives the shading member 3 to move into position.

[0103] In the embodiment of the present application, considering that water droplets and other tiny particles are easily deposited on the lens surface of the camera during daily use, affecting the imaging effect, a cleaning component 7 is also integrated in the camera module to clean the camera body 1.

[0104] Alternatively, if Figure 3 , Figure 6 and Figure 7 As shown, the camera module also includes a cleaning component 7, which is connected to the shading member 3 and is located on the side of the shading member 3 facing the camera body 1. The cleaning component 7 is configured to clean the camera body 1 when the shading member 3 blocks the light input area 11.

[0105] In the embodiment of the present application, the cleaning component 7 can be arranged on the shading portion 31 and located on the side of the shading portion 31 facing the mounting member 4. Furthermore, when the shading member 3 is in the shielding position, the cleaning component 7 can be aligned with the light inlet area 11 to facilitate cleaning of the camera body 1. At the same time, by arranging the cleaning component 7 on the shading member 3, the shielding effect of the light inlet area 11 can be further improved by the cleaning component 7.

[0106] In some embodiments, Figure 3 and Figure 7 As shown, the shape of the cleaning component 7 can be a disk as a whole, and the area of ​​the disk can be not less than or roughly equal to the area of ​​the light input area 11 in the camera body 1, so that when the shading member 3 is stabilized in the shielding position and does not move, the cleaning component 7 can fully clean the light input area 11.

[0107] Alternatively, if Figure 8 and Fig. 9 As shown, the cleaning assembly 7 includes a signal generator 71, a vibrator 72 and a cleaning head 73. The signal generator 71 is connected to the light shielding member 3, and the signal generator 71 is configured to generate a vibration signal; the vibrator 72 is connected to the signal generator 71 and the cleaning head 73 respectively, and the vibrator 72 is configured to drive the cleaning head 73 to vibrate in response to the vibration signal, so that the cleaning head 73 cleans the camera body 1.

[0108] In the present application embodiment, Figure 8 and Fig. 9 As shown, the signal generator 71, the vibrator 72 and the cleaning head 73 can be sequentially arranged on the side of the light shielding member 3 facing the camera body 1. When the light shielding member 3 is in the shielding position and the cleaning assembly 7 is not working, there can be a certain gap between the cleaning head 73 and the camera body 1 to prevent the light shielding member 3 from scratching the camera body 1 when moving between the exposed position and the shielding position. The vibrator 72 can vibrate parallel to the optical axis under the drive of the excitation signal provided by the signal generator 71, so that the cleaning head 73 can contact the camera body 1 and clean the camera body 1.

[0109] In the embodiment of the present application, when the shading member 3 is in the shielding position, the first conductive sheet 51 on the mounting member 4 and the second conductive sheet 52 on the shading member 3 are in contact and electrically connected, so that the circuit where the cleaning component 7 is located can be electrically conductive, thereby allowing the cleaning component 7 to work.

[0110] In some embodiments, the cleaning component 7 can be electrically connected to the second conductive sheet 52. The first conductive sheet 51 can be electrically connected to the power supply circuit. When the first conductive sheet 51 and the second conductive sheet 52 on the light shielding member 3 are in contact and electrically connected, the cleaning component 7 can obtain electricity through the second conductive sheet 52. In addition, since the second conductive sheet 52 and the cleaning component 7 are connected to the circuit, the driving member 21 electrically connected to the first conductive sheet 51 can detect the change of the circuit signal and stop driving. For example, when the second conductive sheet 52 and the cleaning component 7 are connected to the circuit, the driving member 21 can stop driving by detecting the change of the power supply voltage signal, so that the changed power supply voltage signal can be equivalent to the triggered stop signal.

[0111] Optionally, the vibrator 72 is an ultrasonic transducer or a dielectric elastomer.

[0112] In some embodiments, the cleaning component 7 may be an ultrasonic cleaning component. The signal generator 71 is an ultrasonic generator. The ultrasonic generator generally uses a self-excited oscillation circuit structure to generate a signal of a specific frequency. The ultrasonic transducer responds to the signal of the specific frequency and can convert the input electrical power into mechanical power (i.e., ultrasonic wave) and transmit it, thereby driving the cleaning head 73 to vibrate.

[0113] The dielectric elastomer can change its structural shape or volume under the stimulation of an external electric field, thereby automatically converting external electrical energy into an electric machine. When the vibrator 72 is a dielectric elastomer, the dielectric elastomer can expand outward after receiving the vibration signal provided by the signal generator 71, so as to completely attach the cleaning head 73 to the lens of the camera body, and use the cleaning head 73 to transmit the vibration to the lens to achieve cleaning. When the signal generator 71 stops working, the dielectric elastomer can return to its initial state and drive the cleaning head 73 away from the lens surface.

[0114] When the vibrator 72 is a dielectric elastomer, the signal generator 71 is an ultrasonic generator, and may also be a signal generator that provides electrical signals of other frequencies.

[0115] In some embodiments, the cleaning head 73 can be a brush.

[0116] Alternatively, if Figure 1 As shown, the camera module also includes a controller 8, which is configured to control the operation of the driving component 2 and / or the cleaning component 7 in response to a triggering operation on a control program and / or a physical button.

[0117] In some embodiments, when the camera module is used independently, the controller 8 can be integrated in the camera module. In other embodiments, when the camera module is integrated in an electronic device, the controller 8 can also be set independently of other components in the camera module. In addition, the controller 8 can be connected to the drive component 2 and the cleaning component 7 by signal to control the drive component 2 and the cleaning component 7 to work or stop working.

[0118] In some embodiments, the controller 8 can also receive instructions sent by the control program in the terminal device, so that the user can control the camera module through the terminal device. Alternatively, the camera module can also be integrated with a physical button, and the controller 8 can receive a control signal generated by triggering the physical button, so that the user can control the camera module through the physical button.

[0119] In some embodiments, the control program may provide touch buttons on the display interface of the terminal device to facilitate user operation. The terminal device may be an electronic device integrated with the camera module, or may be an electronic device used independently of the camera module.

[0120] The following uses the driving member 21 as a rotating motor as an example to illustrate the process of controlling the operation of the driving component 2 and the cleaning component 7 through the control program.

[0121] In some embodiments, when the user needs to turn off the camera function, the user can click the first touch button in the control program, and the controller 8 receives the first control signal and controls the driving member 21 to rotate forward to drive the shading member 3 to move from the exposed position to the shielding position. When the shading member 3 moves to the shielding position, the positioning member 5 triggers a stop signal, for example, by electrically connecting the first conductive sheet 51 and the second conductive sheet 52 to trigger the stop signal, and the driving member 21 stops rotating upon receiving the stop signal, so that the shading member 3 remains in the shielding position. In this case, the cleaning function of the cleaning component 7 is activated, and the second touch button in the control program becomes operable, for example, the color of the second touch button can change. The user clicks the second touch button, and the controller 8 receives the second control signal and controls the cleaning component 7 to work. After the cleaning component 7 works for a set time, it stops automatically. Alternatively, in response to the second touch button being triggered again, the cleaning component 7 stops working.

[0122] After the cleaning component 7 stops working, the controller 8 can send a completion signal to the terminal device, so that the terminal device displays a completion prompt message in the display interface of the control program.

[0123] After the user sees the completion prompt message or when the user needs to use the camera function, the user can click the first touch button again. In response to the first touch button being triggered again, the driving member 21 reverses to drive the shading member 3 to move from the shielding position to the exposing position.

[0124] The controller 8 can record the time of the shading member 3 moving to the shielding position, and move the shading member 3 to the exposed position for the same time, thereby ensuring that the shading member 3 moves to the exposed position of the initial state. Alternatively, in response to the second position sensor 6 detecting the position of the shading member 3, the driving member 21 is controlled to stop rotating.

[0125] The following uses the driving member 21 as a rotating motor as an example to illustrate the process of controlling the operation of the driving component 2 and the cleaning component 7 through physical buttons.

[0126] In some embodiments, the physical button may include a volume up button and a volume down button, or may be two or more different buttons integrated in the camera module.

[0127] When the user needs to turn off the camera function, he can press the volume up button, the controller 8 receives the first control signal, and controls the driving member 21 to rotate forward to drive the shading member 3 to move from the exposed position to the shielding position. When the shading member 3 moves to the shielding position, the positioning member 5 triggers a stop signal, for example, by electrically connecting the first conductive sheet 51 and the second conductive sheet 52 to trigger the stop signal, and the driving member 21 stops rotating upon receiving the stop signal, so that the shading member 3 remains in the shielding position. In this case, the user presses the volume down button, the controller 8 receives the second control signal, and controls the cleaning component 7 to work. After the cleaning component 7 works for a set time, it stops automatically. Alternatively, in response to the volume down button being pressed again, the cleaning component 7 stops working.

[0128] After the cleaning component 7 stops working, the controller 8 can send a completion signal to the terminal device, so that the terminal device displays a completion prompt message in the display interface of the control program.

[0129] After the user sees the completion prompt message or when the user needs to use the camera function, the user can press the volume up button again. In response to the volume up button being pressed again, the driving member 21 reverses to drive the shading member 3 to move from the shielding position to the exposed position.

[0130] The controller 8 can record the time of the shading member 3 moving to the shielding position, and move the shading member 3 to the exposed position for the same time, thereby ensuring that the shading member 3 moves to the exposed position of the initial state. Alternatively, in response to the second position sensor 6 detecting the position of the shading member 3, the driving member 21 is controlled to stop rotating.

[0131] In the camera module provided in the embodiment of the present application, when the driving component 2 drives the shading member 3 to move in a direction perpendicular to the direction of the camera body 1 to shield the light input area 11 of the camera body 1, the light input area 11 cannot receive external ambient light because it is shielded by the shading member 3, thereby achieving physical shielding of the camera through the shading member 3.

[0132] In addition, the camera module provided in the embodiment of the present application integrates a controller 8, so that the drive component 2 drives the shading member 3 to move by controlling the control program and / or physical buttons, which can conveniently achieve physical shielding of the camera and improve the user experience.

[0133] In addition, the camera module provided in the embodiment of the present application integrates a mounting member 4, a driving member 21, and a guide member 22, etc., in addition to the camera body 1, so that the camera body 1 can be positioned and supported while being protected from peeping by physical shielding. The structure is small in size, easy to operate, and reliable in anti-peeping.

[0134] Furthermore, the camera module provided in the embodiment of the present application achieves efficient cleaning of the camera body 1 and saves space by integrating the cleaning component 7.

[0135] The embodiment of the present application also provides an electronic device, including the camera module as described above. Specifically, the electronic device includes a camera body 1, a driving component 2 and a shading member 3. The driving component 2 is connected to the shading member 3, and the driving component 2 is configured to drive the shading member 3 to move so that the shading member 3 shields or exposes the light-incoming area 11 of the camera body 1, wherein the moving direction of the shading member 3 is perpendicular to the orientation direction of the camera body 1.

[0136] In some embodiments, the camera module can be arranged inside the electronic device.

[0137] In some embodiments, the electronic device further includes at least one of the mounting member 4 , the positioning member 5 , the second position sensor 6 , and the cleaning component 7 as described above.

[0138] like Figure 1 and Figure 2 As shown, the periphery of the mounting member 4 may have a protrusion, and the protrusion may be connected to the middle frame in the electronic device. In other words, when the camera module is integrated in the electronic device, the camera module may be connected to the middle frame.

[0139] In some embodiments, the electronic device includes a controller 8, and the electronic device has at least one of a control program and a physical button. The controller 8 is configured to control the driving component 2 to work in response to a trigger operation on the control program or the physical button. When the electronic device further includes a cleaning component 7, the controller 8 can also be configured to control the cleaning component 7 to work in response to a trigger operation on the control program or the physical button.

[0140] In some embodiments, the controller 8 can be integrated with the camera body 1, the driving assembly 2, the shading member 3, etc., for example, it can be installed on the mounting member 4. Alternatively, the controller 8 can be separately provided from the camera body 1, the driving assembly 2, the shading member 3, etc.

[0141] The control program may be an application program installed in the electronic device. The physical button may include a volume up button and a volume down button of the electronic device.

[0142] The electronic device provided by the present application has the above-mentioned camera module integrated therein, which can protect the camera from peeping through physical shielding, and the camera module is small in size and will not significantly increase the product thickness of the electronic device.

[0143] Furthermore, in view of the limited internal space of the electronic device, the cleaning assembly 7 is integrated on the mounting member 4, so as to achieve efficient cleaning of the camera body 1 and save space.

[0144] In some embodiments, the electronic device may be a mobile phone, a camera, a tablet, a laptop computer, or other device with a camera function.

[0145] The embodiment of the present application further provides a control method, which is executed by the electronic device as described above, and is used to implement occlusion control of a camera in the electronic device. The control method may be a control method for the camera module as described above.

[0146] The electronic device comprises: a camera body 1, a driving component 2 and a shading member 3, wherein the driving component 2 is connected to the shading member 3. The control method comprises: in response to a first trigger operation, controlling the driving component 2 to drive the shading member 3 to move so that the shading member 3 exposes the light-entering area 11 of the camera body 1; in response to a second trigger operation, controlling the driving component 2 to drive the shading member 3 to move so that the shading member 3 shields the light-entering area 11. The first trigger operation and the second trigger operation are triggered by a control program or a physical button, and the moving direction of the shading member 3 is perpendicular to the orientation of the camera body 1.

[0147] In some embodiments, the first trigger operation may be an operation for the user to call the camera function; and the second trigger operation may be an operation for the user to stop calling the camera function. In other words, when the user opens the camera function entrance in the electronic device (for example, opens an application for camera) to call the camera function, the drive component 2 can automatically drive the shading member 3 to move to the exposed position to expose the light inlet area 11 of the camera body 1 without the need for additional trigger operations by the user. Similarly, when the user closes the camera function entrance in the electronic device (for example, exits the application for camera) to stop calling the camera function, the drive component 2 can automatically drive the shading member 3 to move to the shielding position so that the shading member 3 shields the light inlet area 11 without the need for additional trigger operations by the user.

[0148] In other embodiments, after opening the camera function entrance in the electronic device, the user can also control the driving component 2 to work through the control program and / or physical buttons. Alternatively, the driving component 2 can be controlled to work through the control program and / or physical buttons first, and then the camera function entrance in the electronic device can be opened or closed. In other words, the user's operation of calling or stopping the camera function and the user's operation of controlling the driving component 2 to work or stop working can be independent of each other.

[0149] In some embodiments, the electronic device may further include a cleaning component 7 as described above, wherein the cleaning component 7 is connected to the shading member 3 and is located on a side of the shading member 3 facing the camera body 1 .

[0150] The method may further include: in response to receiving a stop signal and a third trigger operation, controlling the cleaning component 7 to work so as to clean the camera body 1. The stop signal is triggered when the shading member 3 moves to the shielding position, and is configured to instruct the driving component 2 to stop driving the shading member 3, and the shading member 3 shields the light-entry area 11 when it moves to the shielding position; the third trigger operation is triggered by a control program or a physical button.

[0151] In some embodiments, when the shading member 3 moves to the shielding position, the positioning member 5 in the electronic device can trigger a stop signal, and the driving member 21 in the driving assembly 2 stops driving the shading member 3 after receiving the stop signal, so as to keep the cleaning assembly 7 on the shading member 3 aligned with the light inlet area 11. In this case, in response to receiving a third trigger operation triggered by the user through a control program or a physical button, the cleaning assembly 7 can start working to clean the camera body 1.

[0152] In the embodiments of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
