Abstract
Description
Technical Field
[0001] This application relates to privacy protection technology, and in particular to an electronic device. Background Technology
[0002] Imaging modules in electronic devices such as conference terminals can capture images using optical lenses. Because some scene information appearing in the field of view of the optical lens may require privacy protection, electronic devices are usually also equipped with shielding covers to block the lens's field of view.
[0003] Specifically, the device panel of the electronic device has a lens window, and the imaging module can be arranged on the inside of the device panel with the optical lens facing the lens window. Furthermore, when it is necessary to block the lens view, the cover plate can be used to cover the lens window from the outside of the device panel.
[0004] The above-mentioned method of covering the lens window with the shielding cover is an exposed installation, and the prior art does not provide a built-in installation scheme in which the shielding cover and the imaging module are located on the inside of the device panel.
[0005] In other words, how to achieve the built-in installation of the shielding cover and the imaging module both located inside the device panel has become a technical problem that needs to be solved in the existing technology. Summary of the Invention
[0006] In embodiments of this application, an electronic device is provided that enables the built-in installation of a cover plate and an imaging module located on the inside of the device panel.
[0007] One embodiment of this application provides an electronic device comprising:
[0008] A device panel having a lens window;
[0009] An imaging module having an optical lens is movably mounted on the inner side of the device panel. The direction of movement of the imaging module is constrained to a first direction perpendicular to the device panel. Furthermore, during the movement of the imaging module along the first direction, the optical axis of the optical lens is kept coincident with the central axis of the lens window.
[0010] A shielding member having a viewing window cover plate, the shielding member being movably mounted on the inner side of the device panel, the direction of movement of the shielding member being constrained in a second direction parallel to the device panel, and the shielding member maintaining the viewing window cover plate parallel to and abutting the device panel during movement along the second direction;
[0011] The movement of the imaging module along the first direction and the movement of the shielding member along the second direction are constrained to be linked as follows:
[0012] When the imaging module moves along the first direction to an imaging position close to the device panel, the lens end face of the optical lens is embedded in the lens window, and the shielding member moves along the second direction to a position to avoid the optical lens.
[0013] When the imaging module moves along the first direction to an idle position away from the device panel, an axial gap is formed between the lens end face of the optical lens and the device panel, and the shielding member moves along the second direction to a shielding position that causes the window cover plate to seal the lens window within the axial gap.
[0014] In some examples, optionally, the window size of the lens window is adapted to the lens end face size of the optical lens; the cover size of the window cover is larger than the window size of the lens window.
[0015] In some examples, the imaging module is optionally connected to the shielding member via a drive connection; it also includes a motor module for generating power output; wherein the power output drives the imaging module and the shielding member to perform the linkage through the drive connection.
[0016] In some examples, the system may optionally include a first adapter fixedly connected to the imaging module and a second adapter fixedly connected to the shielding component; the imaging module and the shielding component are connected by a steering transmission between the first adapter and the second adapter; the motor module is used to generate the power output to one of the first adapter and the second adapter.
[0017] In some examples, the imaging module is optionally fixedly mounted to the first adapter member via a mounting bracket; the shielding member further includes a connecting plate bent relative to the window cover and extending toward the first adapter member, and the second adapter member is integrally integrated into the extended end of the connecting plate.
[0018] In some examples, the first adapter and the second adapter may optionally be in a sliding engagement, the sliding engagement being used to achieve the steering transmission between the first adapter and the second adapter.
[0019] In some examples, optionally, one of the first adapter member and the second adapter member includes a groove; the other of the first adapter member and the second adapter member includes a protrusion; wherein the protrusion is inserted into the groove, the groove includes an inclined groove segment that is inclined relative to both the first direction and the second direction, and the end of the inclined groove segment near the lens window in the second direction is deflected toward the device panel in the first direction, so as to achieve the sliding engagement of the first adapter member and the second adapter member by guiding the movement of the protrusion through the inclined groove segment.
[0020] In some examples, optionally, the first span dimension of the inclined groove segment in the first direction is greater than or equal to the first travel distance of the imaging module for forming the axial gap between the imaging position and the position, and the second span dimension of the inclined groove segment in the second direction is less than the second travel distance of the shielding member between the avoidance position and the shielding position; the groove also includes a straight groove segment parallel to the second direction, the straight groove segment continuing from the end of the inclined groove segment away from the lens window in the second direction, and the sum of the groove length of the straight groove segment and the second span dimension is greater than or equal to the second travel distance.
[0021] In some examples, the system may optionally include a support bracket, the support bracket including a support platform parallel to the first direction and the second direction; the first adapter member and the second adapter member are respectively located on opposite sides of the support platform in a third direction, the third direction being perpendicular to the first direction and the second direction; the support platform has a platform through groove, through which the first adapter member passes to achieve the steering transmission with the second adapter member.
[0022] In some examples, the support bracket may optionally include a second limiting baffle protruding from the support platform along the third direction to the side where the second adapter member is located, the second limiting baffles being arranged in pairs at intervals in the second direction, and the second adapter member being located within a first gap space between the pair of second limiting baffles; the motor module is fixedly mounted on one of the pair of second limiting baffles, and a lead screw coaxially connected to the output shaft of the motor module engages with the second adapter member.
[0023] Optionally, in some examples, the support bracket further includes a first limiting baffle protruding from the support platform along the third direction to the side where the first adapter member is located. The first limiting baffles are arranged in pairs at intervals in the first direction. The first adapter member is located in a first gap space between the pair of first limiting baffles. The pair of first limiting baffles are equipped with first guide rods parallel to the first direction, and the first guide rods pass through the first adapter member to constrain the movement of the imaging module in the first direction through the first adapter member. The support bracket further includes a second limiting baffle protruding from the support platform along the third direction to the side where the second adapter member is located. The second limiting baffles are arranged in pairs at intervals in the second direction. The second adapter member is located in a first gap space between the pair of second limiting baffles. The pair of second limiting baffles are equipped with second guide rods parallel to the second direction, and the second guide rods pass through the second adapter member to constrain the movement of the shielding member in the second direction through the second adapter member.
[0024] In some examples, optionally, a circuit board is also included, the circuit board being stacked inside the device panel; the circuit board has a clearance notch, and the notch size of the clearance notch between a first notch edge and a second notch edge in the second direction is determined based on a second travel distance of the shielding member between the clearance position and the shielding position; the lens window is exposed in the clearance notch, and the lens window is close to the second notch edge; the circuit board also includes a first sensor disposed at the first notch edge and a second sensor disposed at the second notch edge, the first sensor being used to detect a first arrival event of the shielding member at the clearance position, and the second sensor being used to detect a second arrival event of the shielding member at the shielding position.
[0025] In some examples, optionally, the shielding member also has a first lug and a second lug projecting from opposite sides of the window cover along the second direction; when the shielding member reaches the avoidance position, the first lug is within the detection range of the first sensor to trigger the first sensor to generate a first alert signal characterizing the first arrival event; when the shielding member reaches the shielding position, the second lug is within the detection range of the second sensor to trigger the second sensor to generate a second alert signal characterizing the second arrival event.
[0026] Based on the above embodiments, both the imaging module and the shielding member can be movably mounted inside the device panel. By constraining the movement of the imaging module and the shielding member to be linked, the optical lens of the imaging module and the shielding cover of the shielding member can alternately occupy the lens window of the device panel in a mutually asymmetric manner, thereby achieving a built-in installation where the shielding cover and the imaging module are both located inside the device panel. Moreover, based on the linkage between the imaging module and the shielding member, it is not necessary to maintain an axial gap between the optical lens of the imaging module and the device panel to avoid the shielding member. This ensures that the lens end face of the optical lens can be embedded in the lens window when the imaging module assembles an image, thus avoiding the loss of field of view due to the axial gap without having to increase the window size of the lens window.

[0099] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided with reference to the accompanying drawings and embodiments.
[0100] Figure 1 This is a partial structural diagram of the electronic device in an embodiment of this application. Figure 2 For example Figure 1 The diagram shows an exploded view of a local structure of the electronic device. Please refer to [link / reference]. Figure 1 and Figure 2 In embodiments of this application, the electronic device may include a device panel 60, an imaging component 10, and a shielding component 20.
[0101] The device panel 60 may have, but is not limited to, [the following features]. Figure 1 and Figure 2 The physical form represented by the diagram in the middle, that is, Figure 1 and Figure 2 The device panel 60 is only represented as a simplified form that can universally represent any physical shape. Furthermore, regardless of the specific physical shape of the device panel 60, it can always have a lens window 600.
[0102] The imaging module 10 is mounted on the inner side of the device panel 60, and the imaging module 10 has an optical lens 100 and a light sensor such as a CCD (Charge Coupled Device). For example, the imaging module 10 may also include a lens mount 110 and a signal board 120. The optical lens 100 may be fixedly mounted on the lens mount 110, and the light sensor may be fixedly mounted on the signal board 120. The lens mount 110 may be fixedly mounted on the signal board 120 and cover the light sensor, so that the light signal entering within the field of view of the optical lens 100 can be projected onto the light sensor, thereby causing the signal board 120 to output the image signal generated by the light sensor.
[0103] The optical lens 100 of the imaging module 10 can face the lens window 600 of the device panel 60. The optical axis of the optical lens 100 and the central axis of the lens window 600 are both parallel to the first direction Z. Furthermore, the optical axis of the optical lens 100 can coincide with the central axis of the lens window 600.
[0104] Figure 3 For example Figure 1 The diagram shows the linkage position of the electronic device when the cover is open. Figure 4 For example Figure 1 The diagram shows the linkage position of the electronic device when it is in the shielded cover state. Please refer to [link / reference needed]. Figure 1 and Figure 2 See also Figure 3 and Figure 4 (Equipment panel 60) Figure 3 and Figure 4 (Still represented in the simplified form described above), the shielding member 20 is movably mounted on the inner side of the device panel 60. The shielding member 20 has a window cover 200 for selectively covering the lens window 600. The movement direction of the shielding member 20 is constrained to a second direction X parallel to the device panel 60. During movement along the second direction X, the shielding member 20 maintains the window cover 200 parallel to and abutting against the device panel 60. Furthermore:
[0105] When the imaging module 10 needs to acquire images using the optical lens 100, the shielding member 20 moves along the second direction X to a position P_open that avoids the optical lens 100.
[0106] When it is necessary to block the field of view of the optical lens 100 of the imaging module 10, the blocking member 20 moves along the second direction X to the blocking position P_cls, so as to cause the window cover plate 200 to cover the lens window 600 in the axial gap between the lens end face of the optical lens 100 and the device panel 60. The gap size of the axial gap in the first direction Z can be greater than the cover plate thickness of the window cover plate 200 in the first direction Z.
[0107] As an optional solution, the mounting position of the imaging module 10 can normally maintain the aforementioned axial clearance in the first direction Z between the lens end face of the optical lens 100 and the device panel 60. In this case:
[0108] If the window size of the lens window 600 is equal to the radial dimension of the lens end face of the optical lens 100, then the edge of the field of view of the optical lens 100 will be blocked by the device panel 60 due to the aforementioned axial clearance, that is, the axial clearance will cause a loss of the field of view of the optical lens 100.
[0109] If the window size of the lens window 600 is set to be larger than the radial dimension of the lens end face of the optical lens 100 in order to avoid obstructing the lens field of view of the optical lens 100, it will be detrimental to the miniaturization of the device panel 60. Moreover, when the shielding member 20 is in the avoidance position P_open, the axial gap will also appear as an annular gap in the lens window 600 that affects the appearance.
[0110] Therefore, in the embodiments of this application, there is no attempt to maintain the aforementioned axial gap in the first direction Z between the lens end face of the optical lens 100 and the device panel 60 under normal conditions.
[0111] Specifically, such as Figure 1 as well as Figure 3 and Figure 4 As shown in the embodiments of this application, the imaging module 10 is movably mounted on the inner side of the device panel 60. The moving direction of the imaging module 10 is constrained to a first direction Z perpendicular to the device panel 60. During the movement of the imaging module 10 along the first direction Z, the optical axis of the optical lens 100 is kept coincident with the central axis of the lens window 600. Furthermore, the movement of the imaging module 10 along the first direction Z and the movement of the shielding member 20 along the second direction X are constrained to be linked as follows:
[0112] When the imaging module 10 moves along the first direction Z to the imaging position P_cam close to the device panel 60, that is, when the imaging module 10 needs to use the optical lens 100 to acquire an image, the lens end face of the optical lens 100 is embedded in the lens window 600, and the shielding member 20 moves along the second direction X to the avoidance position P_open to avoid the optical lens.
[0113] When the imaging module 10 moves along the first direction Z to an idle position P_idle away from the device panel 60, that is, when it is necessary to block the lens field of view of the optical lens 100, the aforementioned axial gap is formed between the lens end face of the optical lens 100 and the device panel 60, and the shielding member 20 moves along the second direction X to a shielding position P_cls that causes the window cover plate 200 to seal the lens window 600 within the aforementioned axial gap.
[0114] Based on the above structure, both the imaging module 10 and the shielding member 20 can be movably installed inside the device panel 60. By constraining the movement of the imaging module 10 and the shielding member 20 to be linked, the optical lens 100 of the imaging module 10 and the shielding cover 200 of the shielding member 20 can alternately occupy the lens window 600 of the device panel 60 in a mutually avoidant manner, thereby realizing the built-in installation of the shielding cover 20 and the imaging module 10 located inside the device panel 60. Furthermore, based on the linkage between the imaging module 10 and the shielding member 20, it is not necessary to maintain an axial gap between the optical lens 100 of the imaging module 10 and the device panel 60 to avoid the shielding member 20. This ensures that the lens end face 100 of the optical lens 100 can be embedded in the lens window 600 when the imaging module 10 is imaging. Therefore, without having to increase the window size of the lens window 600, the loss of field of view of the optical lens 100 caused by the axial gap can be avoided, which is beneficial to the miniaturization of the device panel 60.
[0115] Figure 5 For example Figure 1 The diagram shows the appearance of the electronic device with the cover open. Figure 6 For example Figure 1 The diagram shows the panel appearance of the electronic device when it is covered by the shielding cover. Please refer to [link / reference]. Figure 1 and Figure 2 See also Figure 5 and Figure 6 (Equipment panel 60) Figure 5 and Figure 6 (The form in question is still represented as the simplified form described above), in the embodiments of this application:
[0116] The size of the lens window 600 can preferably be adapted to the lens end face size of the optical lens 100, so that no annular gap affecting the appearance will appear during the image acquisition period of the imaging module 10. See details. Figure 5 ;
[0117] The cover plate 200 can be larger than the lens window 600. If so, no annular gap affecting the appearance will appear during the period when the lens field of view is obstructed. See details. Figure 6 .
[0118] As an alternative, the movement of the imaging module 10 along the first direction Z and the movement of the shielding member 20 along the second direction X can be driven independently. That is, dual motors can be used to drive the movement of the imaging module 10 and the shielding member 20 respectively, and the independently driven movements of the imaging module 10 and the shielding member 20 can be constrained to be linked by the coordinated control of the dual motors. However, the cost of dual motors is relatively high, and the coordinated control is more complex.
[0119] To save costs and simplify motor control, in the embodiments of this application, the imaging module 10 and the shielding member 20 can be driven together. Furthermore, the movement of the imaging module 10 along the first direction Z and the movement of the shielding member 20 along the second direction X can be constrained by the drive connection between them to the aforementioned linkage. That is, only one driving force is needed to simultaneously drive the linkage of the imaging module 10 and the shielding member 20. For example, the electronic device in the embodiments of this application may also include a motor module 40, which generates power output. This power output can drive the imaging module 10 and the shielding member 20 to perform the aforementioned linkage through the drive connection between them.
[0120] Please review Figures 1 to 4 In embodiments of this application, the electronic device may further include a first adapter 31 fixedly connected to the imaging module 10 and a second adapter 32 fixedly connected to the shielding member 20.
[0121] For example, the imaging module 10 can be fixedly mounted on the first adapter member 31 via a mounting bracket 130. The first adapter member 31 can be in the form of a slider. The mounting bracket 130 can include a fixing plate 131 and a suspension plate 132. The fixing plate 131 can be fixedly connected to the surface of the first adapter member 31 parallel to the first direction Z and the second direction X. The suspension plate 132 can be bent relative to the fixing plate 131 and is parallel to the device panel 60 on the side of the first adapter member 31 facing the device panel 60. The imaging module 10 (i.e., the signal board 120 of the imaging module 10) can be fixedly mounted on the surface of the suspension plate 132 facing the device panel 60. Furthermore, the imaging module 10 (i.e., the signal board 120 of the imaging module 10) can be positioned by the suspension plate 132 so that the optical axis of the optical lens 100 coincides with the central axis of the lens window 600. Thus, as the first adapter 31 is constrained to move in the first direction Z, the imaging module 10 can move synchronously with the first adapter 31 along the first direction Z, and the imaging module 10 maintains the optical axis of the optical lens 100 and the central axis of the lens window 600 during the movement along the first direction Z.
[0122] For example, the shielding member 20 may also include a connecting plate 230 bent relative to the window cover 200 and extending toward the first transition member 31, and the second transition member 32 may be integrally integrated into the extended end of the connecting plate 230. That is, the shielding member 20 and the second transition member 32 may be integrated into a single molded part.
[0123] See also Figures 1 to 4In the embodiments of this application, the moving direction of the imaging module 10 can be indirectly constrained in the first direction Z by constraining the moving direction of the first adapter member 31; similarly, the moving direction of the shielding member 20 can be indirectly constrained in the second direction X by constraining the moving direction of the second adapter member 32.
[0124] For example, in embodiments of this application, the electronic device may further include a support bracket 50, which may be fixedly mounted on a mounting base 30 that is perpendicular to and positioned relative to the device panel 60; that is, the relative position between the support bracket 50 and the device panel 60 is fixed. The support bracket 50 may include a support platform 500 parallel to the first direction Z and the second direction X, and the mounting base 30 may be part of the device housing of the electronic device, or it may be a plate structure mounted on the device housing of the electronic device.
[0125] In this case, the first adapter 31 and the second adapter 32 can be located on opposite sides of the support platform 500 in the third direction Y, which is perpendicular to the first direction Z and the second direction X. That is, the third direction Y and the second direction X are both parallel to the device panel 60.
[0126] The support bracket 50 may further include a first limiting baffle 510 protruding from the support platform 500 along a third direction Y to the side where the first adapter member 31 is located (e.g., the side of the support platform 500 facing away from the mounting substrate 30). The first limiting baffles 510 are arranged in pairs at intervals in the first direction Z. The first adapter member 31 is located in a first gap space between the pair of first limiting baffles 510. Furthermore, the pair of first limiting baffles 510 are also equipped with a first guide rod 515 parallel to the first direction Z. The first guide rod 515 passes through the first adapter member 31. For example, the first adapter member 31 may have a first guide post hole 315 through which the first guide rod 515 passes. Thus, the first adapter member 31 is constrained in the first direction Z within the first gap space between the pair of first limiting baffles 510, thereby constraining the movement of the imaging module 10 in the first direction Z through the first adapter member 31.
[0127] In addition, the suspension plate 132 and the imaging module 10 installed thereon are suspended outside the first interval space on the side near the device panel 60. In this case, the difference between the spatial dimension of the first interval space in the first direction Z (i.e., the spacing distance between a pair of first limiting baffles 510 in the first direction Z) and the component dimension of the first adapter 31 in the first direction Z is used to limit the maximum travel distance of the first adapter 31 in the first direction Z. The maximum travel distance is greater than or equal to the first travel distance of the imaging component 10 between the imaging position P_cam and the idle position P_idle for forming the aforementioned axial gap.
[0128] The support bracket 50 may further include a second limiting baffle 520 protruding from the support platform 500 along a third direction Y to the side where the second transition member 32 is located (e.g., the side of the support platform 500 facing the mounting substrate 30). The second limiting baffles 520 are arranged in pairs at intervals in the second direction X. The second transition member 32 is located in a second interval space between the pair of second limiting baffles 520, and the pair of second limiting baffles 520 are equipped with second guide rods 525 parallel to the second direction. The second guide rods 525 pass through the second transition member 32. For example, the second transition member 32 may have a second guide post hole 325 for the second guide rod 525 to pass through. Thus, the second transition member 32 is constrained in the second direction X within the second interval space between the pair of second limiting baffles 520, and the movement of the shielding member 20 can be constrained in the second direction X by the second transition member 32.
[0129] In addition, both the shielding cover 200 and the connecting plate 230 are located outside the second interval space. In this case, the difference between the spatial dimension of the second interval space in the second direction X (i.e., the spacing distance between a pair of second limiting baffles 520 in the second direction X) and the component dimension of the second transition member 32 in the second direction X is used to limit the maximum travel distance of the second transition member 32 in the first direction Z. The maximum travel distance is greater than or equal to the second travel distance of the shielding member 20 between the avoidance position P_open and the shielding position P_cls.
[0130] In the embodiments of this application, regardless of the form of the first adapter 31 and the second adapter 32, the manner in which the first adapter 31 and the second adapter 32 are fixedly connected to the imaging assembly 10 and the second shielding member 20, or the manner in which the first adapter 31 and the second adapter 32 constrain the movement direction of the imaging assembly 10 and the second shielding member 20, the motor module 40 can be used to generate power output to only one of the first adapter 31 and the second adapter 32. Furthermore, the imaging module 10 and the shielding member 20 can be connected by a steering transmission between the first adapter 31 and the second adapter 32. That is, the support platform 500 can be provided with a platform through groove 530, and the first adapter 31 can pass through the platform through groove 530 to achieve steering transmission with the second adapter 32.
[0131] For example, the motor module 40 can be fixedly mounted on one of a pair of second limiting baffles 520, and the lead screw 400 coaxially connected to the output shaft of the motor module 40 can engage with the second adapter 32, that is, the second adapter 32 can include a screw hole 322 for engaging with the lead screw 400.
[0132] For example, the first adapter 31 and the second adapter 32 can be slidably coupled to achieve steering transmission between the first adapter 31 and the second adapter 32.
[0133] In the embodiments of this application, in order to achieve a sliding fit between the first adapter 31 and the second adapter 32:
[0134] One of the first transition member 31 and the second transition member 32 includes a groove;
[0135] The other of the first transition member 31 and the second transition member 32 includes a protruding post.
[0136] Figure 7 For example Figure 1 The diagram shows a sliding fit mechanism in the electronic device used to achieve steering transmission. Please refer to [link / reference needed]. Figure 7Taking the first adapter 31 including a groove 310 and the second adapter 32 including a protrusion 320 as an example, the protrusion 320 can be inserted into the groove 310. For example, the second adapter 32 may also have a protrusion 321 protruding in the third direction Y. The protrusion 321 may be located in the table surface through groove 530 of the support table 500. The top of the protrusion 321 may be clearance-fitted with the component surface of the first adapter 31 facing the support table 500. Furthermore, the protrusion 320 may protrude from the top of the protrusion 321 and be inserted into the groove 310 of the first adapter 31. In this case, the protrusion height of the protrusion 320 in the third direction Y may be substantially the same as the depth of the groove 310 in the third direction Y.
[0137] The slide 310 may include an inclined groove segment 310a that is inclined relative to both the first direction Z and the second direction X. The end of the inclined groove segment 310a near the lens window 600 in the second direction X is deflected toward the device panel 60 in the first direction Z, so as to achieve a sliding fit between the first adapter member 31 and the second adapter member 32 for steering transmission by guiding the movement of the protrusion 320 through the inclined groove segment 310a.
[0138] In this case, such as Figure 7 As shown, the first span dimension Δz of the inclined slot segment 310a in the first direction Z can be greater than or equal to the first travel distance of the imaging component 10 between the imaging position P_cam and the idle position P_idle for forming the aforementioned axial gap, and the second span dimension Δx of the inclined slot segment 310a in the second direction X is allowed to be less than the second travel distance of the shielding member 20 between the avoidance position P_open and the shielding position P_cls.
[0139] If the second span dimension Δx is less than the second travel distance of the shielding member 20 between the avoidance position P_open and the shielding position P_cls, then the slide 310 may further include a straight groove segment 310b parallel to the second direction, which is connected to the end of the inclined groove segment 310a away from the lens window 600 in the second direction X, and the sum of the groove length of the straight groove segment 310b and the second span dimension Δx is greater than or equal to the second travel distance of the shielding member 20 between the avoidance position P_open and the shielding position P_cls.
[0140] Figure 8 For example Figure 7 The diagram shows the principle of a sliding fit steering transmission. Please refer to [link / reference]. Figure 8 :
[0141] When the protruding post 320 is located in the straight groove section 310b of the slide groove 310, the imaging component 10 is located at the imaging position P_cam, and the shielding member 20 is located at the avoidance position P_open, or at the middle position closer to the shielding position P_cls than the avoidance position P_open.
[0142] When the protrusion 320 is located in the inclined groove section 310a of the slide 310, the imaging assembly 10 moves away from the imaging position P_cam, and the shielding member 20 is closer to the shielding position P_cls than when the protrusion 320 is in the straight groove section 310b of the slide 310.
[0143] Until the protrusion 320 reaches the end of the inclined groove section 310a that is close to the lens window 600 in the second direction X and deflected toward the device panel 60 in the first direction Z, the imaging assembly 10 reaches the idle position P_idle, and the shielding member 20 reaches the shielding position P_cls.
[0144] In the embodiments of this application, such as Figures 1 to 4 as well as Figure 8 As shown, the electronic device may also include a circuit board 80, which is shown in the illustration to fit the simplified form of the device panel 60. Therefore, such illustration should not be construed as an unnecessary limitation on the actual shape and size of the circuit board 80.
[0145] The circuit board 80 can be stacked on the inner surface of the device panel 60, and the circuit board 80 has a clearance notch 850. The notch size of the clearance notch 850 between the first notch edge and the second notch edge in the second direction is based on a second travel distance between the clearance position P_open and the shielding position P_cls, so as to avoid interference and collision between the shielding member 20, which is parallel to the device panel 60, and the circuit board 80 during its movement in the second direction X.
[0146] In this case, the lens window 600 is exposed in the clearance notch 850, and the lens window 600 is close to the edge of the second notch where the second sensor 852 is located. That is, the distance between the lens window 600 and the edge of the second notch in the second direction X is less than the distance between the lens window 600 and the edge of the first notch in the second direction X.
[0147] If the electronic device includes a circuit board 80 having the aforementioned clearance notch 850, the circuit board 80 may further include a first sensor 851 disposed at the first notch edge of the clearance notch 850 and a second sensor 852 disposed at the second notch edge of the clearance notch 850. The first sensor 851 is used to detect a first arrival event of the shielding member 20 in the clearance position P_open, and the second sensor 852 is used to detect a second arrival event of the shielding member 20 in the shielding position P_cls.
[0148] For example, the shielding member 20 may also have a first lug 210 and a second lug 220 protruding from opposite sides of the window cover 200 along a second direction X. When the shielding member 20 reaches the avoidance position P_open, the first lug 210 is within the detection range of the first sensor 851, triggering the first sensor 851 to generate a first alert signal characterizing a first arrival event. When the shielding member 20 reaches the shielding position P_cls, the second lug 220 is within the detection range of the second sensor 852, triggering the second sensor 852 to generate a second alert signal characterizing a second arrival event. Furthermore, the first alert signal generated by the first sensor 851 and the second alert signal generated by the second sensor 852 can be used to control the start / stop and forward / reverse rotation of the motor module 40.
[0149] In an extended embodiment of this application, the device function of the electronic device may not be limited to image acquisition based on the imaging module 10, but may further have an audio acquisition function based on a microphone. That is, the electronic device may not be limited to an image acquisition device, but may be further configured as an audio and video acquisition device.
[0150] Figure 9 This is a partial structural diagram of the electronic device in the embodiments of this application when it is configured as an audio and video acquisition device. Figure 10 For example Figure 9 The diagram shows the structure of the outer surface of the device panel of the audio / video acquisition device. Figure 11 For example Figure 9 A schematic diagram of the inner surface of the device panel of the audio / video acquisition device shown. Figure 12 For example Figure 9 The diagram shows the assembly relationship between the device panel and circuit board of the audio / video acquisition equipment. Please refer to [link / reference needed]. Figures 9 to 12 In embodiments of this application, if the electronic device is configured as an audio / video acquisition device with image acquisition and audio acquisition functions, then:
[0151] The device panel 60 may have multiple microphone holes 680;
[0152] The circuit board 80 has a circuit board sound transmission hole 880 that is aligned with each pickup hole 680. The circuit board 80 is equipped with a microphone 800 at the through hole opening of each circuit board sound transmission hole 880 facing away from the device panel 60. That is, the circuit board 80 has a microphone 800 and a circuit board sound transmission hole 680 that are corresponding to each pickup hole 680 of the device panel 60.
[0153] A compressible sheet 70 for improving microphone airtightness while ensuring microphone consistency can be further deployed between the device panel 60 and the circuit board 80. That is, the compressible sheet 70 is located between the circuit board 80 and the device panel 60, and the compressible sheet 70 has a sheet sound-transmitting hole 780 communicating between each pickup hole 680 and the corresponding circuit board sound-transmitting hole 880. Thus, a sound transmission channel can be formed between each pickup hole 680 and the corresponding microphone 800, passing through the sheet sound-transmitting hole 780 and the circuit board sound-transmitting hole 880.
[0154] In the embodiments of this application, such as Figure 12 As shown, in order to facilitate the coaxial positioning of the pickup hole 680, the sheet sound-transmitting hole 780, and the circuit board sound-transmitting hole 880, the device panel 60 may include a panel positioning post 690, the compressible sheet 70 may include a sheet positioning hole 790, and the circuit board 80 may include a circuit board positioning hole 890. Furthermore, through the positioning and insertion of the sheet positioning hole 790 and the circuit board positioning hole 890 with the panel positioning post 690, the compressible sheet 70 can be positioned such that each sheet positioning hole 790 is coaxially aligned with the corresponding pickup hole 680, and the circuit board 80 can be positioned such that each circuit board sound-transmitting hole 680 is coaxially aligned with the corresponding pickup hole 680.
[0155] In specific assembly, the compressible sheet 70 can be stacked and mounted on the inner surface of the device panel 60 before the circuit board 80, and can be bonded to the inner surface of the device panel 60. For example, the compressible sheet 70 may include any type of foam such as PE (Polyethylene) foam. In this case, the compressible sheet 70 can be bonded to the inner surface of the device panel 60 by means of adhesive application. Alternatively, the compressible sheet 70 may also include double-sided adhesive with a foam material such as PE foam as the interlayer. In this case, the compressible sheet 70 can be bonded to the inner surface of the device panel 60 using its own adhesive properties, and can also be bonded to the circuit board 80. That is, the compressible sheet 70 can be further bonded to the device panel 60 and the circuit board 80.
[0156] For the circuit boards 80 stacked on the inner surface of the device panel 60, constraints need to be applied to prevent the circuit boards 80 from moving away from the device panel 60. In the embodiments of this application, the constraint on the circuit boards 80 is a snap-fit method.
[0157] Figure 13 For example Figure 9 The image shows a cross-sectional view of the device panel and circuit board of the audio / video acquisition equipment in its assembled state. Please refer to [link / reference]. Figure 11 and 12 See also Figure 13In embodiments of this application, the device panel 60 also has a snap fastener 650 disposed at the edge of the panel.
[0158] For example, the device panel 60 can be made of plastic material such as PC (Polycarbonate), and the buckle 650 can be integrally molded during the injection molding process of the device panel 60. Figure 3 and Figure 5 As can be seen, the device panel 60 may have injection molding process holes 655 at the base of each clip 650 to prevent structural changes during injection molding. In this case, to prevent injection molding structures such as injection molding process holes 655 from affecting the appearance of the outer surface of the device panel 60, such as... Figure 9 and Figure 13 As shown, the outer surface of the device panel 60 may be further covered with a decorative sheet 90, and the decorative sheet 90 has a sheet clearance hole 980 arranged in alignment with the pickup hole 680.
[0159] During the stacking and assembly of circuit boards 80, circuit boards 80 can be moved towards the device panel 60 along the first direction Z, and the circuit boards 80 can press the latches 650 to deflect outward from the edge of the circuit boards 80, thereby overcoming the obstruction of movement of the circuit boards 80 by the latches 650. Furthermore, when the circuit boards 80 reach the inner surface of the device panel 60 where the compressible sheet 70 is laid, the pressure of the circuit boards 80 on the latches 650 disappears, allowing the latches 650 to return to their original deflected state and engage at the edge of the circuit boards 80. Figure 13 The retaining and limiting end 651 of the clip 650 shown can be pressed against the surface of the circuit board 80 facing away from the device panel 60 at the edge of the circuit board 80 to achieve the snap-fit of the circuit board 80. Compared with the method of using multiple screws to fasten the circuit board 80, the assembly method of using the clip 650 to snap-fit the circuit board 80 is simpler.
[0160] As an optional optimization, to improve the smoothness of the circuit board 80 during the stacking assembly process and reduce collision damage between the circuit board 80 and the clip 650, such as Figure 13As shown, the edge of the circuit board 80 may have a board edge chamfer 855, which can be formed using CNC (Computerized Numerical Control). The board edge chamfer 855 is used to deflect the latch 650 outwards from the edge of the circuit board 80 during the stacking assembly process where the circuit board 80 moves along the first direction Z toward the device panel 60. More preferably, the latching and limiting end 651 of the latch 650 may have a guide slope 652 on the side facing away from the device panel 60, and the board edge chamfer 855 can slide in contact with the guide slope 652 during the stacking assembly process of the circuit board 80, causing the latch 650 to deflect outwards from the edge of the circuit board 80.
[0161] When the circuit board 80 is stacked on the inner surface of the device panel 60 where the compressible sheet 70 is laid, the latches 650 of the device panel 60 exert a latching force on the circuit board 80 toward the device panel 60. This latching force can prevent the circuit board 80 from moving away from the device panel 60. In addition, the latching force exerted by the latches 650 on the circuit board 80 toward the device panel 60 can also cause the circuit board 80 to make compressive deformation in a first direction Z perpendicular to the device panel 60 through surface contact with the compressible sheet 70. For example, the PE foam in the compressible sheet 70 may be compressed and deformed.
[0162] Since the compressible sheet 70, which is compressed and deformed, can fit tightly with both the circuit board 80 and the device panel 60, the compression and deformation of the compressible sheet 70 can make the two ends of each sheet sound-permeable hole 780 seamlessly connected with the connected pickup hole 680 and the circuit board sound-permeable hole 880, and form a sealed sound transmission channel for the corresponding microphone 800.
[0163] Therefore, the sound transmission channels connecting each pickup hole 680 and its corresponding microphone 800, passing through the sheet sound-permeable hole 780 and the circuit board sound-permeable hole 880, can all be sealed and surrounded by the seamlessly connected walls of the pickup hole 680, the sheet sound-permeable hole 780, and the circuit board sound-permeable hole 880. Consequently, the sound transmission channels of each microphone 800 can be sealed and protected in the same way, thereby improving the airtightness of the microphone 800 while maintaining consistency.
[0164] Based on the above structure, the embodiments of this application have also made various local optimizations, which will be described in detail below.
[0165] In the embodiments of this application, such as Figure 11As shown, in order to ensure that the compression deformation of the compressible sheet 70 caused by the snap-fit occurs at least in the sheet area where the sound-permeable hole 780 of the sheet is connected to the sound-collecting hole 680 and the sound-permeable hole 880 of the circuit board, each sound-collecting hole 680 is located adjacent to the corresponding snap-fit 650.
[0166] For example, multiple microphone holes 680 can be distributed in a linear region extending along a second direction X (i.e., the length direction of the rectangular device panel 60) parallel to the device panel 60. This linear region is located on a third direction Y (i.e., the width direction of the rectangular device panel 60) parallel to the device panel 60 and perpendicular to the second direction X, near one side panel edge (i.e., one side long edge of the device panel 60). In this case, the multiple microphone holes 680 can be arranged adjacent to the latches 650 deployed along the side panel edge in a one-to-one correspondence.
[0167] Based on the above-mentioned optimized arrangement, the snapping force generated by the snap fastener 650 can be applied to the sheet area where the sound-permeable hole 780, the pickup hole 680, and the sound-permeable hole 880 of the circuit board meet, thereby helping to ensure that the compression deformation of the compressible sheet 70 caused by the snapping force occurs at least in the sheet area where the sound-permeable hole 780, the pickup hole 680, and the sound-permeable hole 880 of the circuit board meet, thus reducing the risk of seal failure.
[0168] In the embodiments of this application, such as Figure 11 and Figure 13 As shown, each pickup hole 680 may further have an annular boss 685 on the outer periphery of the opening on the inner surface of the device panel 60. In this case, the compression deformation of the compressible sheet 70 can be locally enhanced in the sheet area where the compressible sheet 70 contacts the annular boss 685 (i.e., the sheet area where the sound transmission hole 780 is located).
[0169] For example, the spacing D0 of the latching and limiting end 651 of the latch 650 relative to the inner surface of the device panel 60 in the first direction Z is less than the sum of the protrusion height h0 of the annular boss 685 in the first direction Z, the thickness of the circuit board 80, and the normal thickness of the compressible sheet 70. Furthermore, by setting the dimensional relationship between the spacing D0, the protrusion height h0, and the thickness of the circuit board 80 and the normal thickness of the compressible sheet 70, the compression deformation of the compressible sheet 70 can be locally enhanced to a preset compression amount (e.g., 50%) in the sheet area where the compressible sheet 70 contacts the annular boss 685.
[0170] This can further improve the tightness of the seamless connection between the two ends of each sheet sound-permeable hole 780 and the connected pickup hole 680 and circuit board sound-permeable hole 880, thereby reducing the risk of seal failure and improving the reliability of the consistent sealing of the sound transmission channel between each pickup hole 680 and the corresponding microphone 800.
[0171] In the embodiments of this application, the main function of the compressible sheet 70 is to provide sealing protection for the sound transmission channel. Therefore, the sheet size of the compressible sheet 70 can be designed to cover only the deployment area of the multiple pickup holes 680 on the device panel 60. For example, as Figure 11 As shown, a plurality of pickup holes 680 can be distributed in a linear region extending along a second direction X (i.e., the length direction of the rectangular device panel 60) parallel to the device panel 60, and the compressible sheet 70 is in the form of a strip covering the linear region.
[0172] In this case, the size of the compressible sheet 70 is smaller than the size of the circuit board 80, for example, as Figure 12 and Figure 13 As shown, the strip width of the compressible sheet 70 in the third direction Y is smaller than the board width of the circuit board 80 in the third direction Y.
[0173] Due to the aforementioned dimensional differences, the localized area where the circuit board 80 contacts the compressible sheet 70 is tightly compressed under clamping force, while other areas of the circuit board 80 not in contact with the compressible sheet 70 may be in a relaxed state. For example, the clips 650 may be distributed on opposite sides of the device panel 60 in the third direction Y (i.e., a pair of long edges of the rectangular device panel 60), and the linear area where multiple pickup holes 680 are deployed and the strip-shaped compressible sheet 70 are located near one side of the panel edge. In this case, the area of the circuit board 80 in contact with the compressible sheet 70 can be tightly compressed with a row of clips 650 at that side of the panel edge, while the other side of the circuit board 80 has a gap fit with a row of clips 650 at the other side of the panel edge. Such a difference in force is detrimental to the stability of the clamping fit between the circuit board 80 and the device panel 60.
[0174] To improve the stability of the snap-fit between the circuit board 80 and the device panel 60, in the embodiments of this application, the inner surface of the device panel 60 may also have a leveling rib 670. Furthermore, the snap-fit force generated by the latch 650 causes the circuit board 80 to contact the leveling rib 670 outside the compressible sheet 70, so that the stress state of the local area where the circuit board 80 contacts the compressible sheet 70 is approximately the same as the stress state of other areas where the circuit board 80 does not contact the compressible sheet 70. For example, as... Figure 11 and Figure 12As shown, the leveling rib 670 can extend parallel to the second direction X, and the leveling rib 670 can be arranged at intervals with the linear area where multiple pickup holes 680 are deployed in the third direction Y. Preferably, the leveling rib 670 can be close to the opposite edge of the linear area where multiple pickup holes 680 are deployed and the edge of the strip-shaped compressible sheet 70 is located in the third direction Y.
[0175] In the embodiments of this application, in order to further improve the signal quality of the audio signal collected by the microphone 800, a noise reduction medium 95 may be further provided. For example, the noise reduction medium 95 may include silicone material.
[0176] like Figure 9 and Figure 13 As shown, the noise reduction medium 95 can surround the microphone 800 on the surface of the circuit board 80 facing away from the device panel 60 to block noise on the side of the microphone 800 facing away from the sound transmission channel. For example, please pay special attention to Figure 13 The noise reduction medium 95 has a medium cavity 950 on the medium surface that contacts the circuit board 80, which corresponds to the microphone 800. Each microphone 800 can be located in the corresponding medium cavity 950. In order to align the microphone 800 with the medium cavity 950, the noise reduction medium 95 can have a medium positioning hole 990 for interlocking with the panel positioning post 690.
[0177] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
