Description

Technical Field

[0001] This application relates to the field of camera technology, and more specifically, to a blocking sheet, a camera blocking device, and an electronic device. Background Technology

[0002] Existing electronic devices are usually equipped with camera devices. In order to protect personal privacy, camera blocking devices (such as blocking plates) are usually also provided. The blocking plate is placed in the viewing window of the camera device to block the lens of the camera device when the camera device is not in use, and to remove the blocking plate to expose the lens when the camera device is in use.

[0003] Currently, some camera devices have a dual-camera structure, which requires a larger viewing window area to meet emission requirements. To meet the blocking requirements, the size of the blocking plate also needs to be larger. However, when a large blocking plate moves along a non-linear trajectory on a non-planar surface (such as a curved or arc-shaped surface), problems such as protrusions, wear, and noise may occur, affecting the normal movement of the blocking plate. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a shielding plate, a camera shielding device, and an electronic device, aiming to resolve problems such as partial protrusions, wear, and noise that occur when the shielding plate moves on a non-planar surface, affecting the normal movement of the shielding plate and its shielding effect.

[0005] In a first aspect, this application provides a shielding plate, which includes a shielding portion, a connecting portion, and a positioning member; the shielding portion is used to shield a camera; the connecting portion is connected to the shielding portion and is used to connect to an external driving structure, and the connecting portion can drive the shielding portion to move along a non-linear motion trajectory under the drive of the driving structure; the positioning member is connected to the connecting portion and is located on the side of the connecting portion facing the camera, the positioning member abuts against the housing of the camera and applies a constraint force to the shielding portion along a first direction; wherein, the first direction intersects with the motion trajectory direction of the shielding portion.

[0006] Based on the shielding plate of this application embodiment, the driving structure drives the shielding plate to move along a non-linear motion trajectory within the sliding gap. The positioning member abuts against the housing, so that the two can apply forces to each other during the movement, thereby limiting the shielding part. For example, when the shielding part moves along the second direction, since the shielding part moves along a non-linear motion trajectory, the shielding part may be subjected to a compressive force in the first direction. At this time, since the positioning member abuts against the housing, the positioning member will generate a constraint force in the first direction. This constraint force is opposite to the compressive force to offset the compressive force, so that the shielding part can move along a non-linear motion trajectory under the limiting effect of the positioning member. That is, the positioning member will apply a constraint force to the shielding part to offset the compressive force in the first direction, thereby avoiding the problem of protrusion in the first direction when the shielding part moves along a non-linear motion trajectory within the sliding gap. This avoids problems such as wear and noise caused by partial protrusion of the shielding part, improves the service life of the shielding part and the shielding plate, and enables the shielding plate to move normally to ensure the shielding reliability of the shielding plate.

[0007] In one possible implementation, the positioning element includes at least one first positioning patch and at least one first positioning protrusion; one side of the first positioning patch is attached to the connecting portion, and the first positioning patch is located on the side of the connecting portion facing the camera; the first positioning protrusion is fixed to the other side of the first positioning patch, the first positioning protrusion abuts against the housing of the camera, and applies a restraining force to the blocking portion along a first direction.

[0008] In this implementation, the first positioning protrusion abuts against the housing to provide a constraint force to the blocking portion along the first direction. This constraint force counteracts the compressive force, thereby preventing problems such as protrusion, wear, and noise in the blocking portion, improving the service life of the blocking portion and the blocking plate, and ensuring the blocking plate can move normally to guarantee the blocking reliability of the blocking plate. Simultaneously, the first positioning protrusion is fixedly connected to the connecting portion via a first positioning patch. The first positioning patch and the connecting portion are in surface contact, meaning the contact area is large and the connection is strong, improving the connection strength between the first positioning protrusion and the connecting portion, thus ensuring the limiting effect of the first positioning protrusion.

[0009] In one possible implementation, the connecting part is provided with a first connecting hole; the positioning member includes at least one second positioning patch and at least one second positioning protrusion; the second positioning patch is provided with a second connecting hole, one side of the second positioning patch is attached to the connecting part so that the second connecting hole communicates with the first connecting hole, and the second positioning patch is located on the side of the connecting part facing the camera; the second positioning protrusion passes through the second connecting hole and the first connecting hole, the second positioning protrusion abuts against the housing of the camera, and applies a restraining force to the blocking part along the first direction.

[0010] In this implementation, the second positioning protrusion abuts against the housing to provide a constraint force to the blocking portion along the first direction. This constraint force counteracts the compressive force, thereby preventing problems such as protrusion, wear, and noise in the blocking portion, improving the service life of the blocking portion and the blocking plate, and ensuring the blocking plate can move normally to guarantee the blocking reliability of the blocking plate. Simultaneously, the second positioning protrusion passes through the second connecting hole and the first connecting hole to achieve a fixed connection with the second positioning patch and the connecting portion, respectively, resulting in a high degree of connection strength and ensuring the limiting effect of the second positioning protrusion.

[0011] In one possible implementation, the blocking part is provided with connecting parts at opposite ends along the first direction, and the positioning member includes two second positioning patches and two second positioning protrusions, with one side of each of the two second positioning patches abutting against the two connecting parts.

[0012] In this implementation, by setting two connecting parts, the reliability of the movement of the blocking part within the sliding gap can be improved, and the problem of deviation in the movement trajectory of the blocking piece can be avoided, thereby improving the accuracy of the movement of the blocking piece within the sliding gap.

[0013] In one possible implementation, the dimension of the connecting portion along the second direction is larger than the dimension of the blocking portion along the second direction, so as to form a first clearance notch at one end of the blocking portion along the second direction; wherein, a first connecting hole is provided on the connecting portion adjacent to the first clearance notch, and one side of the second positioning patch is fitted with the connecting portion adjacent to the first clearance notch so that the second connecting hole communicates with the first connecting hole.

[0014] In one possible implementation, the positioning component further includes a positioning bracket, which fits into the shielding portion adjacent to the first clearance notch. The two ends of the positioning bracket are bent to connect to two second positioning patches respectively, and the positioning bracket is located on the side of the shielding portion facing the camera.

[0015] In this implementation, the positioning bracket and the shielding part form a double-layer composite structure to disperse the stress during movement, thereby avoiding the problem of excessive stress causing bulging, so that the shielding piece can move normally, thus ensuring the shielding reliability of the shielding piece. Moreover, the structure is simple and the manufacturing cost is low.

[0016] In one possible implementation, the dimension of the connecting portion along the second direction is larger than the dimension of the blocking portion along the second direction, so as to form a second clearance notch at the other end of the blocking portion along the second direction.

[0017] In this implementation, by forming a second clearance notch at the tail of the shielding part, the stress area of ​​the shielding part during movement can be reduced, thereby releasing the stress on the shielding part during movement, further ensuring the reliability of the shielding plate's movement, and thus ensuring the shielding effect of the shielding plate.

[0018] In one possible implementation, the material of the shielding part includes at least one of fabric, ultra-thin glass, and plastic film; and / or, the material of the positioning element is plastic.

[0019] In one possible implementation, a prompt is provided on the side of the obstruction away from the camera.

[0021] Thirdly, this application provides an electronic device, including the camera blocking device, camera module, and housing described in the second aspect; the camera module includes a camera; the housing includes a first housing and a second housing, the first housing and the second housing are connected and form a sliding gap, and a positioning member abuts against the second housing.

[0042] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, and circuits have been omitted so as not to obscure the description of this application with unnecessary detail.

[0043] Existing electronic devices (such as computers, cameras, and monitors) typically include camera units to meet the needs of recording, video, or monitoring. These camera units usually consist of a housing and a lens, with a viewing window on the housing opposite the lens. To protect personal privacy, a blocking device (such as a shutter) is usually installed at the viewing window to cover the lens when the camera is not in use; when the camera is in use, the shutter is moved away from the viewing window to expose the lens, thus meeting normal usage requirements.

[0044] With the improvement of camera device functions, camera devices are gradually developing towards multi-camera structures. For example, taking a dual-camera structure, the camera device includes two cameras, one for wide-angle shooting and the other for telephoto, to achieve optical zoom and avoid image quality loss. Compared to single-camera structures, dual-camera structures are larger, requiring a correspondingly larger viewport area to meet the emission requirements. Simultaneously, to meet occlusion requirements, the size of the occlusion plate also needs to be larger. However, the internal space of the camera device is limited, and the traditional horizontal movement of the occlusion plate is not suitable for scenarios with large viewport areas. Therefore, a technique for moving the occlusion plate on non-planar surfaces (such as curved or arc surfaces) has been proposed to meet the movement requirements of larger occlusion plates. However, when a large occlusion plate moves along a non-linear trajectory on a non-planar surface, problems such as bulging, wear, and noise may occur, affecting the normal movement of the occlusion plate and thus its occlusion effect.

[0045] Therefore, this application provides a shielding plate, a camera shielding device, and an electronic device. The positioning member of the shielding plate can apply a constraint force to the shielding part along a first direction. This constraint force is opposite to the squeezing force during the movement to offset the squeezing force, so as to avoid problems such as protrusion, wear, and noise when the shielding part moves along a non-linear motion trajectory on a non-planar surface. This improves the service life of the shielding part and the shielding plate, and at the same time enables the shielding plate to move normally to ensure the shielding reliability of the shielding plate.

[0046] The shielding sheet, camera shielding device, and electronic device provided in this application will be described exemplarily below with reference to the accompanying drawings.

[0047] This application provides an electronic device, such as... Figure 1As shown, the electronic device may include a camera module 3 and a housing 4. The camera module 3 includes a camera located inside the housing 4. The housing 4 has a viewing window 4B, allowing the camera module 3 to perform functions such as recording, video capture, or monitoring through the viewing window 4B. It is worth noting that the size of the viewing window 4B can be set according to the size of the camera module 3. For example, when the camera module 3 adopts a single-camera structure, its overall size is smaller, so the area of ​​the viewing window 4B can be set smaller; when the camera module 3 adopts a dual-camera structure, its overall size is larger, so the area of ​​the viewing window 4B can be set larger. This application does not impose specific limitations in this regard.

[0048] To protect personal privacy, in one example, the electronic device may also include a camera blocking device. When the camera module 3 is not needed, the camera blocking device blocks the lens of the camera module 3; when the camera module 3 is needed, the camera blocking device is moved away from the viewing window 4B to expose the lens of the camera module 3, thereby meeting normal usage requirements. For example, as shown... Figure 2 As shown, the camera blocking device may include a blocking plate 1 and a driving structure 2. The blocking plate 1 is located inside the housing 4. The driving structure 2 is used to drive the blocking plate 1 to move inside the housing 4 to move closer to the viewing window 4B to the closed position, thereby blocking the lens of the camera module 3, or away from the viewing window 4B to the open position, thereby exposing the lens of the camera module 3.

[0049] To allow the shielding plate 1 to move normally within the housing 4, a sliding gap is typically provided within the housing 4 to facilitate the movement of the shielding plate 1. The driving structure 2 can drive the shielding plate 1 to move within the sliding gap to a closed or open position, for example, as shown in... Figure 3 As shown, the housing 4 includes a first housing 41 and a second housing 42. The first housing 41 and the second housing 42 are connected and form a sliding gap 4A. The driving structure 2 is used to drive the blocking plate 1 to move within the sliding gap 4A. It is worth noting that, in order to reduce the space occupied by the blocking plate 1 in the horizontal direction of the housing 4, that is, to reduce the space occupied by the blocking plate 1 on the plane of the lens surface, in one example, as... Figures 3 to 5 As shown, the sliding gap 4A provided inside the housing 4 can have a certain curvature, so that the blocking plate 1 can move along a non-linear trajectory within the sliding gap 4A. When the blocking plate 1 moves to the closed position, as... Figure 4 As shown, the blocking plate 1 covers the lens of the camera module 3 and is located below the viewing window 4B. At this time, the tail of the blocking plate 1 is located in the sliding gap 4A; when the blocking plate 1 moves to the open position, as shown... Figure 5 As shown, the entire shielding plate 1 is located on the sliding gap 4A to reduce the space occupied by the shielding plate 1 on the plane where the lens surface is located.

[0050] When the camera module 3 adopts a dual-camera structure, the size of the shielding plate 1 needs to be correspondingly larger. However, when a larger shielding plate 1 moves within the curved sliding gap 4A, problems such as partial protrusion, wear, and noise may occur, affecting the normal movement of the shielding plate 1 and thus its shielding effect. To avoid the above problems and ensure the shielding reliability of the shielding plate 1, in one example, such as Figure 6 As shown, the shielding plate 1 may include a shielding part 11, a connecting part 12, and a positioning member 13. The shielding part 11 is used to shield the camera. The connecting part 12 is connected to the shielding part 11 and to an external driving structure 2. The connecting part 12 can drive the shielding part 11 to move along a non-linear motion trajectory under the drive of the driving structure 2. The positioning member 13 is connected to the connecting part 12 and is located on the side of the connecting part 12 facing the camera. The positioning member 13 abuts against the housing 4 of the camera and applies a constraint force to the shielding part 11 along the first direction AA, so that the shielding part 11 can move along the second direction BB within the sliding gap 4A. Here, it is worth noting that the first direction AA intersects with the motion trajectory direction of the shielding part 11, and the second direction BB is parallel to the motion trajectory direction of the shielding part 11, that is, the second direction BB and the motion trajectory direction of the shielding part 11 are in the same direction. The positioning member 13 can limit the connecting part 12, so that it can be kept moving in the second direction BB.

[0051] In this example, when the drive structure 2 drives the shielding plate 1 to move along a non-linear motion trajectory within the sliding gap 4A, the positioning member 13 abuts against the housing 4, so that the two can exert force on each other during the movement, thereby limiting the shielding part 11. For example, when the shielding part 11 moves along the second direction BB, since the shielding part 11 moves along a non-linear motion trajectory, the shielding part 11 may be subjected to a squeezing force in the first direction AA. At this time, since the positioning member 13 abuts against the housing 4, the positioning member 13 will generate a constraint force in the first direction AA. This constraint force is opposite to the squeezing force to offset the squeezing force, so that the shielding part 11 can move along the second direction BB under the limiting action of the positioning member 13. The second direction BB here can refer to the horizontal direction. That is, the positioning member 13 will apply a constraint force to the blocking part 11 so that the blocking part 11 can move on the horizontal plane in the horizontal direction. This avoids the problem that the blocking part 11 may have a protrusion in the vertical direction when it moves along a non-linear motion trajectory within the sliding gap 4A. This avoids the problem of the blocking part 11 being worn and generating noise due to the partial protrusion of the blocking part 11, and improves the service life of the blocking part 11 and the blocking plate 1. At the same time, it allows the blocking plate 1 to move normally to ensure the blocking reliability of the blocking plate 1.

[0052] In order for the positioning member 13 to restrict the movement of the blocking part 11 in the second direction BB, the positioning member 13 can cooperate with the housing 4 to achieve the limiting purpose. For example, the positioning member 13 can abut against the second housing 42 to apply a restraining force to the blocking part 11 during movement, thereby restricting the movement of the blocking part 11 in the second direction BB within the sliding gap 4A. For example, Figures 7 to 9 As shown, the second housing 42 may include a limiting groove 42A and a limiting part 421 provided on one side of the limiting groove 42A. A limiting through hole is provided on the bottom wall of the limiting groove 42A to limit the camera in the camera module 3, so as to avoid the camera falling off under the action of external force and improve the stability of the camera module 3 in the housing 4. At least one side of the limiting groove 42A is provided with a limiting part 421. When the blocking plate 1 needs to be moved to the closed position or the open position, the driving structure 2 drives the blocking plate 1 to move within the sliding gap 4A. At this time, the positioning member 13 of the blocking plate 1 will abut against the limiting part 421 provided on at least one side of the limiting groove 42A, so that the two can exert force on each other to limit the blocking part 11, so that the blocking part 11 can move in the second direction BB within the sliding gap 4A, thereby avoiding the problem that the blocking part 11 may protrude in the vertical direction when it moves within the sliding gap 4A. This avoids the problem of the blocking part 11 being worn and generating noise due to the partial protrusion of the blocking part 11, improves the service life of the blocking part 11 and the blocking plate 1, and enables the blocking plate 1 to move normally to ensure the blocking reliability of the blocking plate 1.

[0053] The positioning element 13 provided in this application can achieve dual limiting of the obstruction part 11. For example, such as... Figures 10 to 11 As shown, the driving structure 2 can drive the blocking plate 1 to move to the middle position or the closed position within the sliding gap 4A. When the driving structure 2 drives the blocking plate 1 to the closed position, the positioning member 13 will abut against the first housing 41 to limit the blocking part 11. This prevents the blocking part 11 from moving out of position and the driving structure 2 from continuing to drive the blocking part 11 to move without stopping in time, which would affect the blocking effect of the blocking plate 1. Thus, the positioning member 13 can limit the blocking part 11 to move only along the second direction BB, and can also limit the blocking part 11 to the closed position to ensure the accuracy of the movement of the blocking part 11, thereby improving the blocking reliability of the blocking plate 1.

[0054] When the blocking part 11 is provided with a connecting part 12 at only one end (i.e., the blocking part 11 is moved only by the connecting part 12 on one side), there may be a problem that the movement trajectory of the blocking part 11 is deviated. In order to further improve the movement reliability of the blocking piece 1, in one example, such as Figure 6As shown, the blocking part 11 has connecting parts 12 at its two opposite ends along the first direction AA. The positioning member 13 fits into the two connecting parts 12. The first direction AA intersects with the movement trajectory direction of the blocking part 11. The two connecting parts 12 are connected to the driving structure 2, so that the blocking part 11 can be moved under the drive of the driving structure 2. Here, it can be understood that the first direction AA and the second direction BB are perpendicular to each other. That is, when the second direction BB refers to the up and down direction, the first direction AA can refer to the left and right direction. In this way, by setting two connecting parts 12, the reliability of the movement of the blocking part 11 within the sliding gap 4A can be improved, and the problem of deviation in the movement trajectory of the blocking piece 1 can be avoided, thereby improving the accuracy of the movement of the blocking piece 1 within the sliding gap 4A.

[0055] Optionally, the shielding part 11 and the connecting part 12 can be an integral structure or an independent structure, depending on the actual needs. For example, if the manufacturing process is to be simplified, the shielding part 11 and the connecting part 12 can be an integral structure made by the same process; or if maintenance and replacement are to be convenient, the shielding part 11 and the connecting part 12 can be an independent structure. When the connecting part 12 wears out after a long period of use, only the connecting part 12 needs to be replaced, and the shielding part 11 does not need to be replaced, so as to save manufacturing costs.

[0056] In one example, such as Figures 12 to 13 As shown, the dimension of the connecting portion 12 along the second direction BB is larger than the dimension of the blocking portion 11 along the second direction BB, so that a first clearance notch 1A is formed at one end of the blocking portion 11 along the second direction BB. At this time, the positioning member 13 can fit against the connecting portion 12 adjacent to the first clearance notch 1A. For example, as Figure 12 As shown, the positioning member 13 may include at least one first positioning patch 131 and at least one first positioning protrusion 132. One side of the first positioning patch 131 is attached to the connecting portion 12 adjacent to the first clearance notch 1A. The first positioning protrusion 132 is fixed to the other side of the first positioning patch 131. The first positioning protrusion 132 abuts against the housing 4 of the camera, that is, the first positioning protrusion 132 abuts against the limiting portion 421 of the second housing 42, so as to apply a restraining force to the blocking portion 11 along the first direction AA, thereby enabling the blocking portion 11 to move along the second direction BB.

[0057] In this example, the limiting surface of the first positioning protrusion 132 abuts against the second housing 42 to generate a constraint force in the first direction AA. This constraint force counteracts the compressive force, allowing the blocking part 11 to move along the second direction BB under the limiting action of the positioning member 13. This avoids problems such as protrusion, wear, and noise in the blocking part 11, improving the service life of the blocking part 11 and the blocking plate 1. At the same time, it allows the blocking plate 1 to move normally, ensuring the blocking reliability of the blocking plate 1. Meanwhile, the first positioning protrusion 132 is fixedly connected to the connecting part 12 through the first positioning patch 131. The first positioning patch 131 and the connecting part 12 are in surface contact, meaning that the contact area between the two is large and the connection is strong, thereby improving the connection strength between the first positioning protrusion 132 and the connecting part 12, and thus ensuring the limiting effect of the first positioning protrusion 132.

[0058] The specific number of the first positioning patch 131 and the first positioning protrusion 132 can be set according to actual needs. For example, if you want to reduce manufacturing costs, you can set only one first positioning patch 131 and one first positioning protrusion 132. One side of the first positioning patch 131 is attached to any one of the connecting parts 12. In order to further reduce manufacturing costs, you can also set only one connecting part 12, and the first positioning patch 131 is attached to the connecting part 12. To further improve the limiting reliability of the positioning component 13, two first positioning patches 131 and two first positioning protrusions 132 can be provided. One first positioning patch 131 and the first positioning protrusion 132 are fixedly connected to the connecting portion 12 on the left side of the first clearance notch 1A, and the other first positioning patch 131 and the first positioning protrusion 132 are fixedly connected to the connecting portion 12 on the right side of the first clearance notch 1A. In this way, when the blocking portion 11 moves within the sliding gap 4A, the first positioning protrusions 132 on both sides abut against the second housing 42 respectively, thereby applying a constraint force to the blocking portion 11 and improving the limiting effect of the positioning component 13 on the blocking portion 11. The specific number of first positioning patches 131 and first positioning protrusions 132 can also be set to other numbers, which are not specifically limited in this application.

[0059] The first positioning patch 131 and the first positioning protrusion 132 can be an integral structure or independent structures, depending on actual needs. For example, if the manufacturing process is to be simplified, the first positioning patch 131 and the first positioning protrusion 132 can be an integral structure made by the same process. Or, since the first positioning protrusion 132 is subject to wear, if maintenance and replacement are to be convenient, the first positioning patch 131 and the first positioning protrusion 132 can be independent structures. When the first positioning protrusion 132 wears out after a long period of use, only the first positioning protrusion 132 needs to be replaced, without replacing the first positioning patch 131, thus saving manufacturing costs.

[0060] Optionally, the first positioning patch 131 and the connecting part 12 can be fixedly connected by adhesives such as hot melt adhesive film, double-sided tape, and ultraviolet curing optical adhesive (UV). The adhesive has high bonding strength and low cost.

[0061] In another example, such as Figures 14 to 15 As shown, a first connecting hole 12A is provided on the connecting portion 12 adjacent to the first clearance notch 1A. The positioning member 13 may include at least one second positioning patch 133 and at least one second positioning protrusion 134. A second connecting hole 133A is provided on the second positioning patch 133. One side of the second positioning patch 133 is attached to the connecting portion 12 so that the second connecting hole 133A communicates with the first connecting hole 12A. The second positioning protrusion 132 passes through the second connecting hole 133A and the first connecting hole 12A and abuts against the housing 4 of the camera to apply a constraint force to the blocking portion 11 in the first direction AA, so that the blocking portion 11 can move in the second direction BB.

[0062] It is understood that the diameter and shape of the first connecting hole 12A and the second connecting hole 133A match the size and shape of the second positioning protrusion 134, so that the second positioning protrusion 134 can pass through the first connecting hole 12A and the second connecting hole 133A, and simultaneously engage and fix the second positioning protrusion 134 between the first connecting hole 12A and the second connecting hole 133A, thereby ensuring the strong connection between the second positioning protrusion 134 and the first connecting hole 12A and the second connecting hole 133A. For example, for ease of fabrication, the second positioning protrusion 134 can optionally be a cubic structure, in which case the shape of the first connecting hole 12A and the second connecting hole 133A is a square or rectangle matching the cubic structure, and the diameter of the first connecting hole 12A and the second connecting hole 133A is the same as the area of ​​the contact surface in the cubic structure. This application does not impose specific limitations on this.

[0063] In this example, the limiting surface of the second positioning protrusion 134 abuts against the second housing 42 to generate a constraint force in the first direction AA. This constraint force counteracts the compressive force, allowing the blocking part 11 to move along the second direction BB under the limiting action of the positioning member 13. This avoids problems such as protrusion, wear, and noise in the blocking part 11, improving the service life of the blocking part 11 and the blocking plate 1. At the same time, it allows the blocking plate 1 to move normally, ensuring the blocking reliability of the blocking plate 1. Meanwhile, the second positioning protrusion 134 passes through the second connecting hole 133A and the first connecting hole 12A to achieve a fixed connection with the second positioning patch 133 and the connecting part 12, respectively. The connection is highly secure, ensuring the limiting effect of the second positioning protrusion 134.

[0064] The specific number of the second positioning patch 133 and the second positioning protrusion 134 can be set according to actual needs. For example, if you want to reduce manufacturing costs, you can set only one second positioning patch 133 and one second positioning protrusion 134. One side of the second positioning patch 133 is attached to any one of the connecting parts 12. To further reduce manufacturing costs, you can also set only one connecting part 12, and the second positioning patch 133 is attached to the connecting part 12. If you want to further improve the limiting reliability of the positioning member 13, you can set two second positioning patches 133 and two second positioning protrusions 134. One second positioning patch 133 is fixedly connected to the connecting part 12 on the left side of the first clearance notch 1A, and the second positioning protrusion 134 passes through the first connecting hole 12A of the left connecting part 12 to be fixedly connected to the connecting part 12. The other second positioning patch 133 is fixedly connected to the connecting part 12 on the right side of the first clearance notch 1A, and the second positioning protrusion 134 passes through the first connecting hole 12A of the right connecting part 12 to be fixedly connected to the connecting part 12. Thus, when the blocking part 11 moves within the sliding gap 4A, the second positioning protrusions 134 on both sides abut against the second housing 42 respectively, thereby applying a constraint force to the blocking part 11, thereby improving the limiting effect of the positioning member 13 on the blocking part 11. The specific number of the second positioning patch 133 and the second positioning protrusion 134 can also be set to other numbers, and this application does not impose specific restrictions on this.

[0065] The second positioning patch 133 and the second positioning protrusion 134 can be an integral structure or independent structures, depending on actual needs. For example, if the manufacturing process is to be simplified, the second positioning patch 133 and the second positioning protrusion 134 can be an integral structure made by the same process, that is, the second positioning protrusion 134 is fixed in the second connecting hole 133A. As another example, since the second positioning protrusion 134 may wear out, if maintenance and replacement are to be convenient, the second positioning patch 133 and the second positioning protrusion 134 can be independent structures. When the second positioning protrusion 134 wears out after a long period of use, only the second positioning protrusion 134 needs to be replaced, and the second positioning patch 133 does not need to be replaced, thus saving manufacturing costs.

[0066] Optionally, the second positioning patch 133 and the connecting part 12 can be fixedly connected by adhesives such as hot melt adhesive film, double-sided tape, and UV-curable optical adhesive. The adhesive has high bonding strength, which further improves the bonding strength between the second positioning patch 133 and the connecting part 12, and the cost of the adhesive is low.

[0067] When the viewing window 4B is set to a large value or the bending radius of the sliding gap 4A is set to a small value, in order to reduce the stress on the shielding plate 1 in its free state during movement, in one example, such as Figures 16 to 17 As shown, the positioning component 13 may include two second positioning patches 133, two second positioning protrusions 134, and a positioning bracket 135. The positioning bracket 135 is fitted with the shielding portion 11 adjacent to the first clearance notch 1A, and both ends of the positioning bracket 135 are bent to connect to the two second positioning patches 133 respectively. In this way, the positioning bracket 135 and the shielding portion 11 form a double-layer composite structure to disperse the stress during movement, thereby avoiding the problem of excessive stress causing protrusion, so that the shielding piece 1 can move normally, thus ensuring the shielding reliability of the shielding piece 1. Moreover, the structure is simple and the manufacturing cost is low.

[0068] In this example, to simplify the manufacturing process, the two second positioning patches 133, the two second positioning protrusions 134, and the positioning bracket 135 can be an integral structure and use the same structure, such as plastic.

[0069] Optionally, the positioning bracket 135 and the shielding part 11 can be fixedly connected by adhesives such as hot melt adhesive film, double-sided tape, and UV-curable optical adhesive. The adhesive has high connection strength and low cost.

[0070] During the process of the blocking plate 1 moving to the closed position on the sliding gap 4A, since the sliding gap 4A has a certain curvature, in order to avoid excessive stress on the blocking plate 1 during the movement, which could cause the blocking plate 1 to bulge, in one example, such as Figures 16 to 17 As shown, the dimension of the connecting portion 12 along the second direction BB is larger than the dimension of the blocking portion 11 along the second direction BB, so that a second clearance notch 1B is formed at one end of the blocking portion 11 along the second direction BB. Thus, when the blocking piece 1 moves to the closed position within the sliding gap 4A, the second clearance notch 1B at the tail of the blocking piece 1 (i.e., the end of the blocking piece 1 near the sliding gap 4A) reduces the stress area of ​​the blocking portion 11 during movement, releasing the stress on the blocking portion 11 and preventing it from bulging or collapsing due to excessive stress, which could prevent the blocking piece 1 from moving normally to the closed position and thus affect its blocking effect. Therefore, by forming the second clearance notch 1B at the tail of the blocking portion 11, the stress area of ​​the blocking portion 11 during movement can be reduced, thereby releasing the stress on the blocking portion 11 during movement, further ensuring the reliability of the movement of the blocking piece 1, and thus ensuring the blocking effect of the blocking piece 1.

[0071] Optionally, the shape of the second clearance gap 1B can be square, semi-circular, or other irregular shape that can achieve the above function. The specific shape can be set according to actual needs. This application does not impose specific restrictions on this.

[0072] In summary, when the drive structure 2 drives the shielding plate 1 to move along a non-linear motion trajectory within the sliding gap 4A, the positioning member 13 generates a constraint force in the first direction AA. This constraint force counteracts the squeezing force, meaning that the positioning member 13 applies a constraint force to ensure that the shielding part 11 can maintain movement on the horizontal plane in the horizontal direction. This avoids the problem of the shielding part 11 protruding in the vertical direction when it moves along a non-linear motion trajectory within the sliding gap 4A. Consequently, it avoids problems such as wear and noise caused by the partial protrusion of the shielding part 11, thus improving the service life of the shielding part 11 and the shielding plate 1. At the same time, it enables the shielding plate 1 to move normally, ensuring the shielding reliability of the shielding plate 1.

[0073] Optionally, the material of the shielding part 11 can be a plastic film, such as polyimide film (PI) or polyethylene terephthalate (PET). PI and PET have superior mechanical properties, meaning that when the shielding part 11 is made of PI or PET, its tensile strength, toughness, and folding resistance are better, thus preventing the shielding part 11 from collapsing during movement. Furthermore, the shielding part 11 can also be made of more resilient fabrics, ultra-thin glass, plastic films, thin metal sheets, etc., or other materials capable of achieving the above functions. This application does not impose specific limitations on these applications.

[0074] Optionally, the drive structure 2 can adopt a transmission structure such as gears, chains, or belts. For example, when the drive structure 2 can adopt gears, such as... Figures 12 to 17 As shown, the connecting part 12 is provided with a plurality of driving holes 12B arranged along the second direction BB. The driving holes 12B are used to cooperate with gear transmission, that is, the gear teeth contact the driving holes 12B. When the gear starts to run, the gear teeth will sequentially pass through these driving holes 12B to drive the connecting part 12 to move, thereby driving the blocking part 11 to move. When the drive structure 2 adopts other transmission structures, such as chain, belt and other transmission structures, the connecting part 12 can be set to a structure that matches the transmission structure. In this regard, this application does not impose specific limitations.

[0075] When the blocking plate 1 moves to the closed position under the drive of the driving structure 2, in order to allow the driving structure 2 to automatically stop driving and save manpower, in one example, such as Figure 3 As shown, the shielding plate 1 also includes a limiting part 14, which is connected to the side of the connecting part 12 away from the shielding part 11. In this example, as... Figure 3As shown, the camera blocking device may also include a position sensor 5, which is electrically connected to the controller of the drive structure 2. The position sensor 5 can send a corresponding electrical signal to the controller based on the position of the limiting part 14, so that the controller controls the drive structure 2 to stop or maintain the drive based on the electrical signal.

[0076] Specifically, when the controller controls the drive structure 2 to move the blocking plate 1 towards the open position, the limiting part 14 moves away from the position sensor 5. The position sensor 5 sends a first electrical signal to the controller, ensuring that the controller continues to control the drive structure 2 to move the blocking plate 1. When the controller controls the drive structure 2 to move the blocking plate 1 towards the closed position, the limiting part 14 moves closer to the position sensor 5 until it is above the position sensor 5. The position sensor 5 detects the limiting part 14 and sends a second electrical signal to the controller. This second electrical signal indicates that the blocking plate 1 has moved to the closed position, and the drive structure 2 can stop driving. The controller controls the drive structure 2 to stop driving based on this second electrical signal. In this way, by setting the limiting part 14 and the position sensor 5, the movement position of the blocking plate 1 can be accurately detected, avoiding the problem that the blocking plate 1 has not moved to the preset position, affecting the blocking effect of the blocking plate 1. At the same time, through the detection of the position sensor 5, the drive structure 2 can autonomously exit the drive mode based on the controller, without the need for manual operation, saving manpower.

[0077] To allow users to intuitively perceive that the shutter 1 has moved to the closed position, such as Figure 13 and Figure 15 As shown, a prompt 111 can be provided on the side of the shielding part 11 away from the camera (i.e., the front of the shielding part 11). For example, the prompt 111 can be located in the middle of the shielding part 11, and the color of the prompt 111 is different from that of the shielding part 11, so that the user can know from the prompt 111 that the shielding piece 1 has moved to the closed position. Optionally, the prompt 111 can be set on the shielding part 11 by screen printing, embroidery, weaving, or other processes. Other setting processes can also be used, and this application does not impose specific limitations on this.

[0078] It is worth noting that the aforementioned shielding plate 1 is also applicable to single-camera structures or other multi-camera structures. That is, the size of the shielding part 11 and the connecting part 12 in the shielding plate 1 can be adjusted based on different camera modules 3. For example, if the camera module 3 adopts a single-camera structure, the size of the shielding part 11 can be designed to be smaller; if the camera module 3 adopts a multi-camera structure, the size of the shielding part 11 can be designed to be larger. This application does not impose specific limitations on this.
