For example, a background program of the electronic device or a hacker directly calls a camera to acquire an image without permission, and may steal personal privacy information of the user.

Disclosure of Invention

The application provides a displacement assembly, a camera privacy protection structure and method and electronic equipment, and aims to solve the problem that the privacy security of a user is threatened due to unauthorized calling of a camera.

In a first aspect, an embodiment of the present application provides a camera privacy protection structure, which includes a baffle structure and a first displacement assembly. The baffle structure is provided with a first position and a second position which are sequentially arranged along a first direction; in the first position, the baffle structure shields the camera; in the second position, the baffle structure avoids the camera. The first displacement assembly comprises a first elastic part, a first memory alloy wire and a first power supply module. The first elastic piece is connected to the baffle structure and can apply a first elastic force to the baffle structure along the first direction towards the first position side. The first memory alloy wire is connected to the baffle structure along a first direction and can apply a first driving force along the first direction to the baffle structure, and the direction of the first driving force is opposite to that of the first elastic force. The first power supply module is electrically connected with the first memory alloy wire and has a first power supply state and a second power supply state; the first power supply state enables the first memory alloy wire to be in a low-temperature state, and the second power supply state enables the first memory alloy wire to be in a high-temperature state. Under the low temperature state, the first memory alloy wire is in the natural length, and the first elastic component provides first elastic force, and baffle structure is supported at the first position elastically to first elastic force. In the process that the first memory alloy wire is changed from the low-temperature state to the high-temperature state, the first memory alloy wire is heated and shortened, a first driving force is provided to overcome the first elastic force, and the baffle plate structure is driven from the first position to the second position.

The camera privacy protection structure in this application embodiment only needs to make first power module when not accepting the legal camera instruction of transferring, keeps at first power module, can keep the first position of baffling the camera with baffle structure through first elastic component, and it shelters from the protection to apply one deck physics to the camera, improves camera privacy degree of safety. When the camera is normally used, the first power supply module is positioned in the second first power supply module, the first memory alloy wire is heated and shortened, and the baffle plate structure is pulled to the second position which avoids the camera.

Therefore, the camera privacy protection structure can improve the security degree of the camera privacy, and does not influence the normal use of the camera.

In a possible implementation manner, in the first direction, the first elastic element and the first memory alloy wire are located on the same side of the baffle structure or are respectively arranged on two sides of the baffle structure.

In the implementation mode, for the scheme that the first elastic part and the first memory alloy wire are arranged on two sides of the baffle structure, the structure is simple to mount and connect, but the length space in the first direction possibly occupied by the structure is large; for the case that the first elastic member and the first memory alloy wire are arranged on the same side of the baffle structure, the long-direction space occupied by the first elastic member and the first memory alloy wire in the first direction is smaller, and the requirement on the size of the first direction of the installed structure is lower.

In one possible implementation, in the first direction, the first elastic member and the first memory alloy wire are located on the same side of the baffle structure. The first elastic piece is a spiral spring, and the first memory alloy wire penetrates through the inside of the spiral spring.

In the implementation mode, the first memory alloy wire is arranged on the inner side of the spiral spring, so that the structural space is fully utilized, and the compactness of the structure is improved. Moreover, it is relatively easy to ensure that the forces acting on the baffle structure are collinear.

In one possible implementation, the first power module includes a power interface electrically connected to a power source. The first memory alloy wire is electrically connected to the power supply interface. The first memory alloy wire comprises a fixed end, a connecting end and a middle section; the middle section is connected between the fixed end and the connecting end; the connecting end is fixedly connected to the baffle structure, and the fixed end is fixedly connected to the power supply interface.

In the embodiment, the power supply interface part can be used as the basis for the electrical connection structure and the mechanical fixation of the first memory alloy wire at the same time, and the structure is simple and reasonable.

In one possible implementation, the first memory alloy wire is linear; or the first memory alloy wire is in a folded line shape with a corner section, and the memory alloy wire is guided to be folded through the winding pillar supported on the corner section.

When the first memory alloy wire is linear, its structure is simpler. However, when the distance between the first position and the second position is large, the first memory alloy wire needs to be bent, wound and the like for several times, so that the first memory alloy wire is prevented from occupying too large installation space.

The winding post can be a cylindrical body with a smooth cylindrical surface or can be in a pulley shape.

In this embodiment, the first memory alloy wire may be a memory alloy wire made of memory alloys such as Au-Cd, Ag-Cd, Cu-Zn, Fe-Pt, Ti-Ni, and the like, and may be determined according to requirements of stroke, life, size, deformation temperature, deformation rate, and the like when in use.

In a possible implementation manner, the camera privacy protection structure in the scheme further includes a locking assembly. The locking assembly includes a locking member and a second displacement assembly. The locking piece corresponds to the baffle structure in a second direction, and the second direction is vertical to or obliquely intersected with the first direction; the second displacement assembly is in transmission connection with the locking piece and can drive the locking piece to be close to and lock the baffle plate structure along the second direction or to be far away from and unlock the baffle plate structure along the second direction.

In this implementation, through further setting up the locking subassembly, can lock the position that baffle structure is located when needing.

For example, the flapper structure may be locked in the first position by a locking assembly. So, transfer the camera and need make locking subassembly unblock baffle structure earlier, then just can drive baffle structure to the second position through first displacement subassembly, use the camera, camera privacy protection intensity further promotes.

As another example, the flapper structure can also be locked in the second position by a locking assembly when desired. Therefore, when the camera is normally used, the baffle structure can be locked through the locking assembly, the high-temperature state of the first memory alloy wire does not need to be kept, and energy loss is reduced or heat accumulation is caused to damage related devices.

Of course, the locking assembly may also be arranged to be able to lock the first and second positions of the flapper structure, respectively.

In one possible implementation manner, the second displacement assembly includes a second elastic member, a second memory alloy wire and a second power supply module. The second elastic piece is connected to the locking piece and applies a second elastic force to the locking piece, wherein the second elastic force is close to the baffle plate structure along a second direction. The second memory alloy wire is connected to the locking piece along the second direction and can apply a second driving force to the locking piece along the second direction, and the direction of the second driving force is opposite to that of the second elastic force. The second power supply module is electrically connected with the second memory alloy wire and has a third power supply state and a fourth power supply state; the third power supply state enables the second memory alloy wire to be in a low temperature state, and the fourth power supply state enables the second memory alloy wire to be in a high temperature state. Under the low temperature state, the second memory alloy wire is in the natural state, and the second elastic component provides the second elastic force, and the second elastic force supports the locking piece elastically in the position that is close to the baffle structure to make the baffle structure that the locking piece can the locking be located the second position. In the process that the second memory alloy wire is changed from the low-temperature state to the high-temperature state, the second memory alloy wire is heated and shortened, a second driving force is provided to overcome a second elastic force, and the locking piece is driven to a position far away from the baffle structure so that the baffle structure can be unlocked.

In this implementation, exert the effort through second elastic component and second memory alloy silk line jointly to the locking piece, control the position of locking piece through the combination of both applications of force, and then control the position of locking piece locking or unblock baffle structure.

In one possible implementation, the baffle structure has a first buckling portion, and the locking member has a second buckling portion adapted to the first buckling portion. The second buckling part is a boss protruding towards the baffle structure. The first buckling part is a boss protruding towards the locking piece. When the baffle structure is located the second position, the second buckling parts can be close to the baffle structure along the second direction to block the first buckling parts and lock the baffle structure.

In the implementation mode, the second buckling part can be controlled to block the first buckling part, and the locking and unlocking of the baffle plate structure by the locking piece can be conveniently realized.

In one possible implementation, the latch member has a mounting end and a movable end opposite in a first direction; the locking piece is rotatably installed by the installation end of the locking piece, the second buckling part is located at the movable end of the locking piece, and the locking piece can be driven by the second displacement mechanism to rotate by taking the installation end as a rotating shaft to be close to or far away from the baffle structure.

In this implementation, the locking piece realizes that its second buckling parts are close to or keep away from the baffle connecting piece through rotatory mode.

In one possible implementation, the first fastening portion has a first surface and a second surface corresponding to each other along a first direction. The second buckling part is provided with a third surface and a fourth surface which correspond to each other along the first direction. The second surface and the fourth surface are buckling surfaces perpendicular to the first direction, and the second surface and the fourth surface are attached to abut against each other in the state that the first buckling part and the second buckling part are buckled, so that the second buckling part can be locked with the first buckling part. The first surface and the third surface are both wedge surfaces obliquely intersected with the first direction, and the first surface and the third surface are mutually matched; in the process that the first buckling part passes through the second buckling part, the first face and the third face are guided by the wedges and slide relatively.

In order to make the second buckling part clamp the first buckling part along the first direction, the second buckling part has a part corresponding to the first buckling part along the first direction in the natural state. For making first buckling parts can follow the first direction and pass through second buckling parts and not blockked by the second buckling parts, in this scheme, set up to the tapered wedge face that matches each other through second face and fourth face for both can let the position along the second direction relatively through the inclined plane cooperation.

Meanwhile, in the case where the structural form and position tolerance is large or the mounting accuracy or the like is not particularly high, the above-described abduction in the second direction can be achieved by the structural movable range allowed by these tolerances. Of course, since the first memory alloy wire and the first elastic member extend along the connecting path to the baffle structure along the first direction over a large distance, they can usually allow a certain deformation in the second direction without damaging the structure. In addition, when the second elastic member is elastically supported and the second memory alloy wire does not rigidly support the second buckling part, the second buckling part can also realize yielding along the second direction by compressing the second elastic member.

In one possible implementation, the baffle structure includes a baffle portion and a baffle connector; the baffle part is used for shielding or avoiding the camera. The first memory alloy wire, the baffle connecting piece and the baffle part are sequentially connected along a first direction. The first buckling part is arranged on the baffle connecting piece.

The first memory alloy wire, the baffle connecting piece and the baffle part are sequentially connected along the first direction, so that the connecting path from the first memory alloy wire to the baffle structure in the first direction is further increased, and the relative abdication of the first buckling part and the second buckling part is more favorable.

In one possible implementation, the connection between the baffle plate connecting member and the baffle plate portion is a rotating connection, and the rotating shaft of the rotating connection is perpendicular to the plate surface where the baffle plate portion is located.

In this implementation, the baffle connecting piece can use its and the rotation junction between the baffle portion as rotation center, does swing of small circle along the second direction in baffle portion inboard to the adaptation can the small-angle rotation when the locking subassembly is to its application of force in order to realize stepping down of second direction, along stepping down each other of second direction when avoiding the boss of first buckling parts and second buckling parts to be passed through along the first direction relatively along the too big influence of structural connection rigidity.

In a possible implementation manner, the privacy protection structure for a camera in the embodiment of the present application further includes a locking assembly. The locking assembly comprises a locking piece and a second displacement assembly; the locking piece corresponds to the first displacement assembly in a second direction, and the second direction is intersected with the first direction; the second displacement assembly is in transmission connection with the locking piece and can drive the locking piece to be close to or far away from the second displacement assembly along the second direction so as to lock or unlock the baffle plate structure through the second displacement assembly.

In this implementation, the locking assembly is used for locking or unlocking the first displacement assembly, thereby indirectly locking or unlocking the baffle structure.

In one possible implementation, the baffle structure includes a light-blocking region and a light-transmitting region. In the first position, the shading area of the baffle structure corresponds to the camera; in the second position, the light-transmitting area of the baffle structure corresponds to the camera.

Optionally, the baffle structure is provided with a through hole, the area where the through hole is located serves as a light transmitting area, and the light shielding area is located in a partial area of the baffle outside the through hole.

In this implementation, the light-transmitting region may be a hollowed through hole, or may be made of light-transmitting glass or other light-transmitting materials. The shading area can be a complete shading structure, such as a metal plate, glass with a light-tight coating and the like, and can also be a partial shading structure, and only a certain effect of shading the camera is needed.

In this implementation, the light-transmitting area and the light-shielding area may be obtained on a single plate, for example, on the aforementioned baffle portion; or two components can be connected.

In other implementation manners, the baffle structure can be only provided with a shading area, and the whole baffle structure is pulled away from the camera, so that the camera is avoided.

In a second aspect, an embodiment of the present application further provides an electronic device, which includes a body with a camera, a control module, and the foregoing camera privacy protection structure. The body is provided with a sliding groove extending along the first direction, and the baffle plate structure is matched in the sliding groove in a sliding mode. The control module is electrically connected with the first power supply module.

If a legal instruction for calling the camera is not received, the control module controls the first power supply module to be in a first power supply state; and if a legal instruction for calling the camera is received, the control module controls the first power supply module to be switched to the second power supply state.

Due to the adoption of the camera privacy protection structure, the electronic equipment has high camera use safety.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application are described in detail. In the following embodiments, features of the embodiments may be combined with each other without conflict.

The embodiment of the application provides a camera privacy protection structure, can set up in the electronic equipment who has the camera for improve the privacy security that the camera used.

Example one

Referring to fig. 1 and 2 in combination, and to fig. 3 in combination (a camera 200 is additionally shown in dashed lines in fig. 1-3), the present embodiment provides a camera privacy preserving structure 100 that includes a baffle structure 110 and a first displacement assembly 120.

With reference to fig. 1 and 2, the baffle structure 110 has a first position S1 and a second position S2 sequentially arranged along the first direction Y1, and the baffle structure 110 is reciprocally movable between the first position S1 and the second position S2. Referring to fig. 1, in the first position S1, the barrier structure 110 shields the camera head 200; referring to fig. 2, in the second position S2, the barrier structure 110 is clear of the camera head 200. The first displacement assembly 120 includes a first elastic member 121, a first memory alloy wire 122 and a first power supply module 123. The first elastic member 121 is connected to the barrier structure 110 and is capable of applying a first elastic force to the barrier structure 110 along the first direction Y1 toward the first position S1 side. The first memory alloy wire 122 is connected to the barrier structure 110 along the first direction Y1, and is capable of applying a first driving force along the first direction Y1 to the barrier structure 110, wherein the direction of the first driving force is opposite to the first elastic force. The first power supply module 123 is electrically connected to the first memory alloy wire 122 and has a first power supply state and a second power supply state; the first power state can place the first memory alloy wire 122 in a low temperature state, and the second power state can place the first memory alloy wire 122 in a high temperature state. Optionally, the first power supply state is to power off the first memory alloy wire 122, and the second power supply state is to power on the first memory alloy wire 122. When the power is turned on, the first memory alloy wire 122 can generate heat to a high temperature state due to self-resistance; when the power is turned off, the first memory alloy wire 122 is slowly cooled to a low temperature state along with the heat dissipation. The high temperature state and the low temperature state are a set of relative concepts, and the specific temperature value is determined according to different properties of the first memory alloy wire 122.

In other embodiments, the first power supply state and the second power supply state are both states in which the first memory alloy wire 122 is energized, but the magnitude of the current passing through the first memory alloy wire 122 is different in both states.

In the low temperature state, the first memory alloy wire 122 is in the natural length, and the first elastic member 121 provides a first elastic force, which elastically supports the barrier structure 110 at the first position S1;

during the process of changing the first memory alloy wire 122 from the low temperature state to the high temperature state, the first memory alloy wire 122 is heated and shortened to provide the first driving force to overcome the first elastic force, and the baffle structure 110 is driven from the first position S1 to the second position S2.

The camera privacy protection structure 100 in the embodiment of the present application only needs to make the first power supply module 123 remain in the first power supply state when not receiving the instruction of legally calling the camera 200, that is, the first elastic member 121 can keep the baffle structure 110 at the first position S1 where the camera 200 is shielded, so as to apply a layer of physical shielding protection to the camera 200, thereby improving the privacy security degree of the camera 200. When the camera 200 is normally used, the first power supply module 123 is in the second power supply state, so that the first memory alloy wire 122 is heated and shortened, and the baffle structure 110 is pulled to the second position S2 where the camera 200 is avoided.

In this implementation, by configuring the first displacement assembly 120 to include the first elastic member 121 and the first memory alloy wire 122, and the first elastic force of the first elastic member 121 makes the baffle structure 110 tend to remain at the first position S1, a physical barrier is provided for the calling of the camera 200, and only after the first memory alloy wire 122 overcomes the first elastic force under the driving of the first power supply module 123, the camera 200 can be normally used, which increases the calling difficulty of the camera 200, i.e., reduces the risk that the camera 200 is called without permission.

Therefore, the camera privacy protection structure 100 of the present application can improve the privacy security degree of the camera 200, and does not affect the normal use of the camera 200.

In this embodiment, in the first direction Y1, the first elastic member 121 and the first memory alloy wire 122 are located on the same side of the baffle structure 110. In this embodiment, the first elastic element 121 and the first memory alloy wire 122 are overlapped in the first direction Y1, and occupy a small longitudinal space in the first direction Y1, and have a low size requirement on the first direction Y1 of the mounted structure. Optionally, the first elastic member 121 is a coil spring, a channel penetrating along the axial direction is defined inside the first elastic member, and the first memory alloy wire 122 penetrates through the channel inside the coil spring, so that the structural space is fully utilized, and the compactness of the structure is improved. Moreover, it is relatively easy to ensure that the forces acting on the baffle structure 110 are collinear. For example, when the first memory alloy wire 122 is straight, the fixing of the first memory alloy wire 122 can be located at the central axis of the coil spring, so that the two forces acting on the baffle structure 110 can be collinear. In this embodiment, the coil spring is a compression spring that primarily applies a pushing force to the baffle structure 110.

With continued reference to fig. 1 and 2 (see also fig. 3), the first power supply module 123 includes a power supply interface 123a electrically connected to a power supply (not shown). The power supply here may be a power supply provided separately, or may be a battery of the electronic device itself in which the present camera privacy securing structure 100 is installed. In this embodiment, the first memory alloy wire 122 is electrically connected to the power supply interface 123a, so that the power supply can supply power to the first memory alloy wire 122. The first memory alloy wire 122 includes a fixed end D1, a connecting end D2 and a middle section D3, wherein the middle section D3 is connected between the fixed end D1 and the connecting end D2. The connecting end D2 is fixedly attached to the baffle structure 110, either directly or indirectly, and the fixed end D1 is fixedly attached to the power supply interface 123 a. In this embodiment, the power supply interface 123a can serve as a basis for both the electrical connection structure and the mechanical fixation of the first memory alloy wire 122, and the structure is simple and reasonable.

Alternatively, in the case of employing a coil spring as the first elastic member 121, the coil spring may be compressively supported between the power supply interface 123a and the barrier structure 110, and the power supply interface 123a and the barrier structure 110 may respectively provide a support portion for the coil spring so as to support the connection of the coil spring.

In the embodiment shown in fig. 1 to 3, the first memory alloy wire 122 has a linear shape, and has a simple structure, and can be easily inserted into the coil spring and connected.

In other embodiments, the first memory alloy wire 122 may also be configured as a folded wire shape having a corner section D4, and the first memory alloy wire 122 is guided to be folded by the winding pillar 130 supported by the corner section D4. For example, referring to fig. 4, the first memory alloy wire 122 has two corner segments D4, each corner segment D4 has a turning angle of 180 °, and each corner segment D4 is respectively turned and guided by the winding pillar 130. In other embodiments, the first memory alloy wire 122 may also be configured with other zigzag shapes, such as U-shaped, S-shaped, etc.; the first memory alloy wire 122 can be provided with a small pulley or a winding post 130 with a smaller friction coefficient at the winding position so as to reduce the friction force and improve the efficiency of the deformation force; the first memory alloy wire 122 may be wound on a plane on the same plane, or may be wound in a three-dimensional space, and may be specifically disposed as required. It should be noted that the first memory alloy wire 122 can move relative to the winding post 130. The winding post 130 may be a fixed cylinder, which is capable of slidably guiding and turning the first memory alloy wire 122 through a smooth cylindrical surface; the winding post 130 may also be configured in a pulley shape, which itself includes a rotatably disposed roller to reduce friction and deformation force efficiency.

By arranging the winding post 130 to perform several turns and windings on the first memory alloy wire 122, the occupation of an excessive installation space of the first memory alloy wire 122 in the first direction Y1 can be reduced. Alternatively, a longer first memory alloy wire 122 can be obtained with a smaller installation space of the first direction Y1, so that a larger first driving force and deformation amount can be obtained, and the baffle structure 110 can be driven to perform a sufficiently large displacement.

It should be noted that, for the first memory alloy wire 122 in a zigzag shape, if the size is suitable, the installation space can be reduced by partially or completely penetrating the coil spring. Of course, it may be provided in addition to the coil spring.

In this embodiment, the first memory alloy wire 122 may be a memory alloy wire made of memory alloys such as Au-Cd, Ag-Cd, Cu-Zn, Fe-Pt, Ti-Ni, and the like, and may be determined according to the requirements of stroke, life, size, deformation temperature, deformation rate, and the like.

With continued reference to fig. 1 and fig. 2 (see fig. 3 in a matching manner), in the present embodiment, optionally, the camera privacy protecting structure 100 further includes a locking assembly 140.

The locking assembly 140 includes a locking member 141 and a second displacement assembly 150. The locking member 141 corresponds to the barrier structure 110 in the second direction Y2, and the second direction Y2 is perpendicular to or obliquely intersects the first direction Y1, in this embodiment, the second direction Y2 is substantially perpendicular to the first direction Y1. The second displacement assembly 150 is in transmission connection with the locking member 141, and can drive the locking member 141 to approach and lock the barrier structure 110 along the second direction Y2 or move away from and unlock the barrier structure 110 along the second direction Y2.

In this implementation, by further providing the locking assembly 140, the position of the baffle structure 110 can be locked when necessary.

For example, the flapper structure 110 may be locked in the first position S1 by the locking assembly 140. Thus, calling the camera 200 requires that the locking assembly 140 unlock the baffle structure 110, and then the first displacement assembly 120 drives the baffle structure 110 to the second position S2 to use the camera 200, so that the privacy protection strength of the camera 200 is further improved.

As another example, the flapper structure 110 may also be locked in the second position S2 by the locking assembly 140, if desired. Thus, when the camera 200 is in normal use, the blocking plate structure 110 can be blocked by the blocking assembly 140 without maintaining the high temperature state of the first memory alloy wire 122, thereby reducing energy loss or causing heat accumulation to damage related devices.

Of course, the locking assembly 140 may also be configured to lock both the first position S1 and the second position S2 of the flapper structure 110.

In one possible implementation, the second displacement assembly 150 includes a second elastic member 151, a second memory alloy wire 152, and a second power supply module 153. The second elastic member 151 is connected to the locking member 141, and applies a second elastic force to the locking member 141 in the second direction Y2 to approach the barrier structure 110. The second memory alloy wire 152 is connected to the locking member 141 along the second direction Y2, and is capable of applying a second driving force to the locking member 141 along the second direction Y2, wherein the direction of the second driving force is opposite to the second elastic force. The second power supply module 153 is electrically connected to the second memory alloy wire 152, and has a third power supply state and a fourth power supply state; the third power state can place the second memory alloy wire 152 in a low temperature state, and the fourth power state can place the second memory alloy wire 152 in a high temperature state. Alternatively, the third power supply state is to de-energize the second memory alloy wire 152, and the fourth power supply state is to energize the second memory alloy wire 152. When the power is on, the second memory alloy wire 152 can generate heat to a high temperature state due to self resistance; when the power is turned off, the second memory alloy wire 152 is slowly cooled to a low temperature state along with the heat dissipation. The high temperature state and the low temperature state are a set of relative concepts, and the specific temperature value is determined according to different properties of the second memory alloy wire 152.

In the low temperature state, the second memory alloy wire 152 is in the natural state, and the second elastic member 151 provides a second elastic force, which elastically supports the locking member 141 at a position close to the barrier structure 110, so that the locking member 141 can lock the barrier structure 110 at the second position S2;

in the process that the second memory alloy wire 152 changes from the low temperature state to the high temperature state, the second memory alloy wire 152 is heated and shortened to provide a second driving force to overcome the second elastic force, and the locking member 141 is driven to a position far away from the baffle structure 110 to unlock the baffle structure 110.

The second memory alloy wire 152 is made of a material and has a shape selected with reference to the first memory alloy wire 122.

In this implementation, the second elastic member 151 and the second memory alloy wire 152 apply an acting force to the locking member 141 together, and the position of the locking member 141 is controlled by the combination of the two acting forces, so as to control the locking member 141 to lock or unlock the position of the baffle structure 110.

Optionally, the baffle structure 110 has a first engaging portion 110a, and the locking member 141 has a second engaging portion 141a adapted to the first engaging portion 110 a. The second engaging portion 141a is a protrusion protruding toward the baffle structure 110. The first engaging portion 110a is a boss protruding toward the locking member 141. When the baffle structure 110 is located at the second position S2, the second engaging portion 141a can approach the baffle structure 110 along the second direction Y2 to block the first engaging portion 110a and lock the baffle structure 110. In this implementation, the second engaging portion 141a is controlled to block the first engaging portion 110a, so that the locking and unlocking of the baffle structure 110 by the locking member 141 can be conveniently achieved.

In the present embodiment, the locking member 141 has a mounting end D5 and a movable end D6 opposite in the first direction Y1. The locking member 141 is rotatably mounted at the mounting end D5, and the second engaging portion 141a is located at the movable end D6 of the locking member 141 and can be driven by the second displacement mechanism to rotate to approach or separate from the baffle structure 110 by using the mounting end D5 as a rotation axis. Optionally, the movable end D6 of the locking member 141 is pivotally mounted to a stationary post 142. In this implementation, the locking member 141 rotates to enable the second engaging portion 141a to approach or separate from the baffle plate connector 112, i.e. the second direction Y2 is a circular arc direction. When the first direction Y1 is a straight direction, the positional relationship between the second direction Y2 and the first direction Y1 may be a simple intersection or an intersection angle close to 90 ° so that the second engaging portion 141a can be substantially perpendicularly close to or away from the shutter structure 110.

In this embodiment, the first engaging portion 110a has a first plane P1 and a second plane P2 corresponding to the first direction Y1. The second engaging portion 141a has a third face P3 and a fourth face P4 corresponding to each other in the first direction Y1. The second panel P2 and the fourth panel P4 are fastening surfaces perpendicular to the first direction Y1, and in a state where the first fastening portion 110a and the second fastening portion 141a are fastened, the second panel P2 and the fourth panel P4 are attached and abutted to each other, so that the first fastening portion 110a is locked by the second fastening portion 141 a. The first plane P1 and the third plane P3 are both wedge surfaces obliquely intersected with the first direction Y1, and the two surfaces are mutually matched; in the process that the first engaging part 110a passes through the second engaging part 141a, the first plane P1 and the third plane P3 are wedge-guided to each other and slide relative to each other.

In order to allow the second engaging portion 141a to engage with the first engaging portion 110a along the first direction Y1, in this embodiment, the second engaging portion 141a has a portion corresponding to the first engaging portion 110a along the first direction Y1 when the second engaging portion 141a is supported by the second elastic member 151 to a position close to the baffle structure 110. In order to enable the first engaging portion 110a to pass through the second engaging portion 141a in the first direction Y1 without being blocked by the second engaging portion 141a, in the present embodiment, the second plane P2 and the fourth plane P4 are configured as wedge surfaces matching with each other, so that the two can give way relative to the second direction Y2 by the inclined surface matching.

Meanwhile, in the case where the structural form and position tolerance is large or the mounting accuracy or the like is not particularly high, the above-described abduction in the second direction Y2 can be achieved by the structural movable range allowed by these tolerances. Of course, generally, since the first memory alloy wire 122, the first elastic member 121 and the connecting path of the baffle structure 110 extend along the first direction Y1 for a larger distance, it is usually able to allow a certain deformation and yielding in the second direction Y2 without damaging the structure. In addition, the second elastic member 151 is elastically supported, the second memory alloy wire 152 does not rigidly support the second engaging portion 141a, and the second engaging portion 141a can also yield along the second direction Y2 by compressing the second elastic member 151.

With reference to fig. 1 or fig. 2, in a possible implementation manner, the baffle structure 110 includes a baffle portion 111 and a baffle connector 112, where the baffle portion 111 is used to shield or avoid the camera 200 and has a larger area; the baffle plate connector 112 has a substantially strip-shaped configuration extending in the first direction Y1, and has a small area. The first memory alloy wire 122, the baffle connector 112 and the baffle portion 111 are connected in sequence along the first direction Y1. The first engaging portion 110a is disposed on a side of the baffle connector 112 close to the locking member 141, and optionally, a groove 112a is further formed on the baffle connector 112 on a side of the first engaging portion 110a close to the baffle portion 111, for avoiding the second engaging portion 141a in the second direction Y2. The first memory alloy wire 122, the baffle connector 112 and the baffle portion 111 are sequentially connected along the first direction Y1, so that the connection path from the first memory alloy wire 122 to the baffle structure 110 in the first direction Y1 is further increased, which is more beneficial to the relative yielding of the first buckling portion 110a and the second buckling portion 141 a. Alternatively, the connection between the baffle plate connector 112 and the baffle plate portion 111 is a rotating connection, and the rotating axis of the rotating connection is perpendicular to the plate surface where the baffle plate portion 111 is located. As shown in the figure, one end of the shutter link 112 is connected with a rotating pin 112b, a rotating hole 111a is provided at a corresponding position of the shutter portion 111, and the rotating pin 112b is rotatably fitted in the rotating hole 111 a.

In this embodiment, the baffle plate connector 112 can swing slightly in the second direction Y2 in the plate surface of the baffle plate 111 with the rotational connection between the baffle plate connector and the baffle plate 111 as the rotational center, so as to adapt to the small-angle rotation when the locking assembly 140 applies force to the baffle plate to achieve yielding in the second direction Y2, and avoid the mutual yielding in the second direction Y2 when the bosses of the first buckling part 110a and the second buckling part 141a pass through each other along the first direction Y1 due to the excessive structural connection rigidity.

In the foregoing embodiment, the first engaging portion 110a is disposed on the baffle plate connector 112 of the baffle plate structure 110. In other embodiments, the first fastening portion 110a may also be directly disposed on the baffle portion 111, leaving the baffle connector 112 free.

Furthermore, in some other embodiments, the locking mechanism may also indirectly lock or unlock the baffle structure 110 by locking or unlocking the first displacement assembly 120 (not shown).

With continued reference to fig. 1 or fig. 2, in the present embodiment, the baffle structure 110 includes a light-shielding region 110b and a light-transmitting region 110 c. In the first position S1, the light-shielding region 110b of the barrier structure 110 corresponds to the camera 200; in the second position S2, the light-transmissive region 110c of the baffle structure 110 corresponds to the camera head 200.

In this implementation, the transparent region 110c may be a hollowed through hole, or may be made of transparent glass or other transparent materials. The light-shielding region 110b may be a completely light-shielding structure, such as a metal plate, a glass with an opaque coating, or a partially light-shielding structure, and only needs to achieve a certain effect of shielding the camera 200.

In this implementation, the light-transmitting area 110c and the light-shielding area 110b may be obtained on a single plate, for example, on the aforementioned baffle portion 111; or two components can be connected.

In other implementation manners, the barrier structure 110 may be provided with only the light shielding region 110b, and the barrier structure 110 may be pulled away from the camera 200 to avoid the camera 200.

In another implementation, referring to fig. 5 and 6 in combination, the implementation differs from the camera privacy protecting structure 100 shown in fig. 1 and 2 in that the first elastic member 121 and the first memory alloy wire 122 are respectively disposed on two sides of the baffle structure 110 (in fig. 1/2, the first elastic member 121 and the first memory alloy wire 122 are located on the same side of the baffle structure 110). The structure is simple to mount and connect, but can occupy larger length space of the first direction Y1, and can be used when the structure mounting size allows. In this embodiment, the first elastic member 121 may be an extension spring, which mainly applies a tensile force to the barrier structure 110. Specifically, a fixing body 160 may be disposed at a side where the first elastic member 121 is located, and one end of the first elastic member 121 is connected to the fixing body 160, and the other end is connected to the baffle structure 110.

In this embodiment, the fixing body 160, the first elastic member 121, the baffle structure 110, the first memory alloy wire 122, and the first power module 123 are sequentially connected along the first direction Y1, and the fixing body 160 and the first power module 123 are respectively fixed and disposed with a constant distance therebetween. The force of the first elastic member 121 and the first memory alloy wire 122 against the shutter structure 110 is collinearly reversed in the first direction Y1, and the position of the shutter structure 110 can be controlled by the energization and de-energization of the first power supply module 123.

Referring to fig. 7 and 8, the embodiment further provides an electronic device 010, which includes a body 300 having a camera 200, a control module 400, and the aforementioned camera privacy protecting structure 100. The housing 310 of the body 300 is provided with an oblong hole 311 corresponding to the camera 200.

The body 300 has a sliding groove 320 extending in the first direction Y1 therein, and the barrier structure 110 is slidably fitted in the sliding groove 320 and is located between the camera 200 and the housing 310. The control module 400 is electrically connected to the first power supply module 123. If a legal instruction for calling the camera 200 is not received, the control module 400 controls the first power supply module 123 to be in a first power supply state; if a legal instruction for calling the camera 200 is received, the control module 400 controls the first power supply module 123 to switch to the second power supply state. Since the electronic device 010 uses the camera privacy protection structure 100, the camera 200 is highly safe to use. Optionally, for the camera privacy protecting structure 100 with the locking assembly 140, the control module 400 may also be electrically connected to the second power supply module 153 for controlling the locking assembly 140 to lock or unlock the barrier structure 110.

The electronic device 010 in this embodiment may be a computer device such as a desktop computer, an all-in-one machine, and a notebook, may be a home or office device such as a smart screen, a television, a projector, and a monitoring camera, and may also be another device having the camera 200 such as a mobile phone. With the increasing use of these devices, the definition and the photographing breadth of the camera 200 are increasing, and in addition, various applications may call the camera 200 to collect user data in the background to set privacy, and the privacy risk of the user generated by the camera 200 is also increasing.

Since the electronic device 010 provided by this embodiment has the foregoing camera privacy protecting structure 100, it can conveniently realize that the camera 200 is automatically shielded when necessary. For example, in the case that a non-user actively opens the camera 200, the barrier structure 110 of the camera privacy protection structure 100 shields the camera 200, so as to protect the privacy of the user; or user perception becomes important when the camera head 200 is turned on.

The embodiment of the present application further provides a camera privacy protection method, which is based on the aforementioned camera privacy protection structure 100. The camera privacy protection method comprises the following steps: if a legal command for calling the camera 200 is not received, the first power supply module 123 is kept in the first power supply state, so that the first memory alloy wire 122 is in the low temperature state, and the first elastic force of the first elastic member 121 keeps the baffle structure 110 at the first position S1, so as to shield the camera 200.

The camera privacy protection method is based on the camera privacy protection structure 100, and can effectively protect the privacy of the camera 200.

The embodiment of the present application further provides another camera privacy protection method, which is based on the aforementioned camera privacy protection structure 100 provided with the locking assembly 140. The camera privacy protection method comprises the following steps:

if a legal command for calling the camera 200 is not received, the first power supply module 123 is kept in the first power supply state, so that the first memory alloy wire 122 is in the low temperature state, and the first elastic force of the first elastic member 121 keeps the baffle structure 110 at the first position S1, so as to shield the camera 200;

if a legal instruction for calling the camera 200 is received, the first power supply module 123 is switched to the second power supply state, so that the first memory alloy wire 122 is changed to the high-temperature state, the first memory alloy wire 122 is heated and shortened, and the baffle structure 110 is driven to the second position S2 to avoid the camera 200; simultaneously, the locking assembly 140 is caused to lock the baffle structure 110 in the second position S2; after the baffle structure 110 is locked, the first power supply module 123 returns to the first power supply state;

if an instruction for stopping calling the camera 200 is received, the locking assembly 140 is enabled to unlock the baffle structure 110; the first elastic member 121 is caused to push the shutter structure 110 from the second position S2 back to the first position S1.

The following describes the camera 200 calling process and the camera 200 closing process in detail.

Referring to the call flow of the camera 200 shown in fig. 8, initially, the camera 200 is in the privacy-protecting state, and the barrier structure 110 shields the camera 200. When the camera 200 is legally invoked (e.g., autonomously invoked by a user, invoked by an allowed application), the first power supply module 123 switches from the power-off mode (the first power supply state) to the power-on mode (the second power supply state) to supply power to the first memory alloy wire 122, the first memory alloy wire 122 is powered on and heated and then contracts, and the baffle structure 110 is pulled to move to the second position S2 by overcoming the acting force of the first elastic member 121; in the process that the baffle structure 110 moves to the second position S2, the first engaging portion 110a passes through the second engaging portion 141a and is engaged by the second engaging portion 141a, so that the baffle structure 110 is locked at the second position S2 by the locking piece 141; at this time, since the position of the baffle structure 110 is blocked, the first power supply module 123 can be powered off to save energy and avoid excessive heating of the first memory alloy wire 122; thus, the camera 200 can enter a stable normal use state. Of course, after the baffle structure 110 is locked, the first power supply module 123 may continuously supply power without power failure, thereby further ensuring the position of the camera 200.

Referring to the closing process of the camera 200 shown in fig. 9, at the beginning, the camera 200 is in the working state, and the barrier structure 110 avoids the camera 200. When the camera 200 needs to be closed (for example, a user closes the camera 200 autonomously and an unallowed background illegally calls the camera 200), the second power supply module 153 supplies power to the second memory alloy wire 152, the second memory alloy wire 152 is electrified and heated and then contracts, the action force of the second elastic member 151 is overcome to pull the locking member 141 to rotate away from the baffle structure 110, and the locking member 141 unlocks the baffle structure 110; when the first power module 123 is kept or switched to the power-off mode (the first power state), the first elastic element 121 drives the baffle structure 110 to move to the first position S1, and the camera 200 returns to the privacy protection state (the first position S1).

With the above description, the camera privacy protection structure 100, the camera privacy protection method, and the electronic device 010 in the embodiment of the present application have at least one of the following technical effects:

1. a full-automatic camera 200 shielding scheme is provided, and the user experience is greatly improved;

2. the problem that the shielding mechanism is manually operated and is forgotten to be pushed is solved;

3. only when the user actively calls the camera 200 can the baffle be triggered to move, so that the risk of non-active background operation is reduced. Moreover, the state change of the position of the baffle plate structure facilitates the perception of the camera 200 by a client when the camera is opened.

Example two

Referring to fig. 10, the present embodiment provides a displacement assembly 500 for moving the target object 600 between a third position S3 and a fourth position S4 sequentially arranged along the third direction Y3. The displacement assembly 500 includes an elastic member 510, a memory alloy wire 520, and a power supply module 530. The power module 530 and the target 600 are spaced apart along the third direction Y3. The elastic member is a coil spring elastically supported between the power supply module 530 and the target member 600. The memory alloy wire 520 passes through the coil spring, and has one end fixedly connected to the power supply module 530 and the other end fixedly connected to the target 600. The memory alloy wire 520 is powered by the power module 530 and can be powered on to shorten or powered off to restore to its natural length.

It can be seen that the displacement assembly 500 of the present embodiment can be used as the first displacement assembly 120 or the second displacement assembly 150 of the first embodiment to provide displacement control.

Although the present application has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the present application.
