Description

Technical Field

[0001] This utility model relates to the field of camera blocking technology, specifically an indoor camera blocking device. Background Technology

[0002] With the rapid development of smart home and security monitoring technologies, indoor cameras have been widely used in various indoor scenarios such as homes, offices, hotel rooms, and rental apartments, playing a vital role in protecting property security, enabling remote monitoring, and improving management efficiency. However, while indoor cameras are widely used, privacy and security issues are becoming increasingly prominent, becoming a core pain point restricting their further promotion and improving user experience. On the one hand, in some scenarios (such as family bedrooms), users have a strong need for privacy protection during specific times (such as resting, changing clothes, or handling private matters), requiring the camera's recording function to be temporarily disabled. On the other hand, although most existing cameras are equipped with physical switches or software sleep functions, there are still many limitations in practical applications: current mainstream software sleep and recording shutdown functions rely on the collaborative work of the camera's operating system, network transmission protocols, and terminal control apps. However, in the event of network attacks, system vulnerabilities, or malware intrusions, these software control functions may be bypassed, causing the camera to continue recording even when the user mistakenly believes it is "off," resulting in privacy leaks.

[0003] To avoid the security risks of software control, most users choose to cover the camera lens using traditional physical methods such as tape or tissues. However, these methods have obvious drawbacks: tape, tissues, and other materials easily leave adhesive residue and fibers on the lens surface, affecting the normal image quality of the camera, and are difficult to clean; for cameras installed at high locations, they are extremely inconvenient to operate. Utility Model Content

[0004] The purpose of this utility model is to provide an indoor camera blocking device, which uses two interlocking shells to cover the camera and a rotating first blocking component to block the camera lens, thus solving the problem of inconvenience in blocking cameras using traditional methods.

[0005] To address the problems of existing technologies, this utility model provides an indoor camera blocking device, comprising: a housing assembly capable of covering the camera and rotating with the camera; and a first blocking assembly disposed on the housing assembly and capable of rotation for blocking the camera lens; the housing assembly includes a first housing and a second housing capable of covering the outside of the camera, the first housing and the second housing being able to be spliced ​​together to cover the outside of the camera and rotating synchronously with the camera, a through groove being formed at the splice of the first housing and the second housing for forming the lens shooting channel of the camera, and the first blocking assembly being rotatable to cover the through groove formed by the first housing and the second housing for blocking the camera lens.

[0006] Preferably, the first housing and the second housing are hemispherical, and a cavity for accommodating the camera is formed inside the first housing and the second housing.

[0007] Preferably, the cavities inside the first and second housings are provided with a plurality of clamping members that can contact the camera housing, and the clamping members are arc-shaped to adapt to the shape of the camera.

[0008] Preferably, the first blocking component includes a first blocking plate disposed on the housing component and capable of pitch rotation. The first blocking component also includes a first driving mechanism disposed on the housing component for driving the first blocking plate to pitch rotation. When it is necessary to block the lens of the camera, the first blocking plate can pitch rotation to the lens to block the lens of the camera.

[0009] Preferably, the first blocking component includes a second blocking plate disposed on the housing component and capable of horizontal rotation. The second blocking plate also includes a second driving mechanism disposed on the housing component for driving the second blocking plate to rotate horizontally. When it is necessary to block the camera lens, the second blocking plate can rotate horizontally to the lens to block the camera lens.

[0010] Preferably, the bottom of the housing assembly is further provided with a fixing sleeve assembly that can be fixed to the lower part of the camera. The fixing sleeve assembly includes a first clamping sleeve and a second clamping sleeve. The first clamping sleeve and the second clamping sleeve can be sleeved on the outside of the housing assembly. The upper end of the first clamping sleeve and the second clamping sleeve is provided with an annular groove. The bottom of the housing assembly is provided with an annular rail that cooperates with the annular groove and can rotate in the annular groove. The fixing sleeve assembly is provided with an opening that corresponds to the lens at the lower part of the camera. The fixing sleeve assembly is also provided with a second blocking assembly that can block the lower lens.

[0011] Preferably, the second shielding component includes a fixing ring installed at the opening of the fixing sleeve component, a plurality of third shielding plates are rotatably disposed in the fixing ring and evenly arranged along the fixing ring, and a guide post is also provided on the third shielding plate. A rotating component is rotatably disposed outside the fixing ring, and an arc-shaped groove corresponding to the third shielding plate is opened on the rotating component. The guide post can slide in the arc-shaped groove.

[0012] Preferably, the second shielding component includes a fourth shielding plate that is tiltable and can cover the lower lens of the camera.

[0013] Preferably, the second shielding component includes a guide groove disposed at the opening of the fixed sleeve component and a fifth shielding piece slidably disposed in the guide groove for shielding the lower lens of the camera.

[0014] The second shielding component includes a sixth shielding plate rotatably disposed at the opening of the fixed sleeve component. The sixth shielding plate can rotate up and down to shield the lower lens of the camera.

[0015] The advantages of this utility model compared to the prior art are:

[0016] The housing assembly of this application is constructed by splicing together two hemispherical structures, a first housing and a second housing. This splicing structure allows the housing assembly to cover the outside of the camera, forming a wraparound mounting base for the camera body. To ensure stable connection and synchronous movement between the housing assembly and the camera, clamping components are provided inside both the first and second housings. These clamping components can contact the outer wall of the camera. When the camera is externally rotated for monitoring needs, the housing assembly can rotate synchronously with the camera under the force of the clamping components, effectively preventing relative displacement between the housing assembly and the camera. This ensures that the camera is not interfered with by the housing assembly during normal operation and guarantees the normal realization of its monitoring angle adjustment function. Regarding the need to obstruct the upper lens of the camera, this application includes a first obstruction component. This first obstruction component is mounted on the housing assembly. Through the preset movement of the first obstruction component, it can cover the upper lens of the camera, thereby reliably obstructing the upper shooting area of ​​the camera and meeting the user's need for privacy protection of the upper lens in specific scenarios. Considering that some cameras have a lower lens structure, this application also includes a fixing sleeve assembly to achieve complete camera obstruction. This fixing sleeve assembly can be installed in the lower area of ​​the camera, forming a dual mounting structure corresponding to the housing assembly. Simultaneously, a second obstruction assembly is integrated into the fixing sleeve assembly. Through the motion control of the second obstruction assembly, the lower lens of the camera can be specifically obstructed, ultimately achieving full-lens coverage obstruction for cameras with a dual-lens structure, further expanding the adaptable scenarios and functional completeness of the device.

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 , Figure 2 and Figure 5As shown, this utility model provides an indoor camera blocking device, including: a housing assembly 1, capable of covering the camera and rotating with the camera; and a first blocking assembly 2, disposed on the housing assembly 1 and rotatable to block the camera lens. The housing assembly 1 includes a first housing 12 and a second housing 14 that can cover the outside of the camera. The first housing 12 and the second housing 14 can be spliced ​​together to cover the outside of the camera and rotate synchronously with the camera. The housing assembly 1 is also provided with an electronic control box 11. A through groove is formed at the splicing point of the first housing 12 and the second housing 14 to form a lens shooting channel for the camera. The first blocking assembly 2 can rotate to cover the through groove formed by the first housing 12 and the second housing 14 to block the camera lens. The first housing 12 and the second housing 14 are hemispherical, and a cavity for accommodating the camera is formed inside the first housing 12 and the second housing 14. Both the first housing 12 and the second housing 14 are hemispherical structures. When joined together, they form an internal cavity that can accommodate the camera, providing complete coverage of the camera's exterior. This through-slot serves as the camera's lens capture channel, ensuring that the camera can acquire external images normally when unobstructed, and preventing the housing assembly 1 from physically hindering the camera's normal operation. Furthermore, when the camera rotates externally to adjust the monitoring angle, the first housing 12 and the second housing 14 can rotate synchronously with the camera, ensuring the relative position stability of the device and the camera. The cavities inside the first housing 12 and the second housing 14 are equipped with several clamping members 13 that can contact the camera's outer shell. These clamping members 13 have an arc-shaped structure to adapt to the camera's shape. Its core function is to generate a stable clamping force through the tight fit between the curved surface and the camera housing, firmly fixing the housing assembly 1 to the camera. To ensure stable clamping, a buffer pad, made of rubber or other elastic material, can be adhered to the contact surface between the clamping member 13 and the camera housing to increase clamping stability and prevent the housing assembly 1 from shifting or falling off due to camera rotation. The electronic control box 11 is integrated on the housing assembly 1 and serves as the core control unit of the device, mainly used to house electronic control components such as circuit boards and batteries. The first shielding assembly 2 is mounted on the housing assembly 1 and has rotatable characteristics. Its core function is to selectively shield the camera lens: when the user does not require privacy protection and the camera needs to work normally, the first shielding assembly 2 is in the unshielded position, not shielding the through slot formed by the splicing of the first housing 12 and the second housing 14, ensuring that the camera lens can pass through the through slot to take pictures normally; when the user has privacy protection needs, the first shielding assembly 2 rotates under the control of the electronic control box 11 until it completely covers the through slot, thereby shielding the camera lens, cutting off its shooting path, and achieving the privacy shielding function.

[0032] The first housing 12 and the second housing 14 are connected together to cover the camera, so that the camera is housed in the cavity inside the two housings. The first housing 12 and the second housing 14 are fixed by magnetic attraction or bolts, or glue can be used for bonding. The arc-shaped clamping parts 13 inside the first housing 12 and the second housing 14 are in close contact with the camera housing, ensuring that the through groove at the splicing point is aligned with the camera lens to form a complete shooting channel. When no obstruction is needed, the first obstruction component 2 remains in the unobstructed position, and the camera takes pictures normally through the slot. If the camera is rotated externally for monitoring purposes, the housing component 1 rotates synchronously with the camera under the action of the clamping member 13, and the slot is always aligned with the lens. When the user triggers a privacy protection command, such as remote control, the circuit board in the control box 11 sends a rotation control signal and power to the first obstruction component 2, driving the first obstruction component 2 to rotate around a preset axis. When the first obstruction component 2 rotates to a position that completely covers the slot, its structure blocks the camera lens, blocking the lens's shooting path and achieving privacy protection. When it is necessary to resume shooting, the first obstruction component 2 is driven to rotate in the opposite direction, leaving the area covered by the slot, and the camera resumes normal shooting function.

[0033] Example 1: Refer to Figures 2-3 As shown, the first blocking component 2 includes a first blocking plate 21a disposed on the housing component 1 and capable of pitch rotation. The first blocking component 2 also includes a first driving mechanism disposed on the housing component 1 for driving the first blocking plate 21a to pitch rotation. When it is necessary to block the lens of the camera, the first blocking plate 21a can pitch rotation to the lens to block the lens of the camera. The first drive mechanism includes a connector 22a connected to the first shielding plate 21a. The connector 22a is arc-shaped, with rotating shafts on both sides that can be inserted into holes on the side of the housing assembly 1. The connector 22a is elastic, and a first gear 23a is fixed to one end of the connector 22a. The first drive mechanism also includes a first rotary drive component 24a disposed outside the housing assembly 1. The output end of the first rotary drive component 24a is connected to a second gear 25a, which meshes with the first gear 23a. The first rotary drive component 24a serves as the power source for the first drive mechanism and can be a stepper motor, servo motor, or other drive element with precise speed and angle control. Its core function is to receive control signals from the circuit board inside the control box 11, convert electrical energy into rotational mechanical energy, and transmit the power to the second gear 25a through the output end, thereby achieving precise control of the rotation angle and speed of the first shielding plate 21a and ensuring the reliability and stability of the shielding action.

[0034] When a user triggers a privacy protection command, the circuit board inside the control box 11 sends a rotation control signal to the first rotation drive 24a. After receiving the signal, the first rotation drive 24a starts and drives the second gear 25a at the output end to rotate. Since the second gear 25a meshes with the first gear 23a, the rotational power of the second gear 25a is transmitted to the first gear 23a through tooth surface contact, causing the first gear 23a to rotate synchronously. The first gear 23a drives the connecting piece 22a fixed to it to rotate around the two side pivots, and the connecting piece 22a in turn drives the first blocking piece 21a to rotate towards the through slot. When the first blocking piece 21a rotates to a preset position that completely covers the through slot, the circuit board controls the first rotation drive 24a to stop working, and the first blocking piece 21a remains in that position, thus blocking the camera lens. When the user needs to restore the camera's shooting function, the circuit board in the control box 11 sends a rotation control signal to the first rotation drive 24a; the first rotation drive 24a drives the second gear 25a to rotate in the opposite direction, and through gear meshing, drives the first gear 23a and the connecting piece 22a to rotate in the opposite pitch direction, thereby causing the first blocking piece 21a to rotate away from the through slot; when the first blocking piece 21a rotates to the non-blocking position completely away from the through slot, the circuit board controls the first rotation drive 24a to stop, and the camera lens resumes normal shooting through the through slot.

[0035] Example 2: Refer to Figure 4 As shown, the first blocking component 2 includes a second blocking plate 21b disposed on the housing component 1 and capable of horizontal rotation. The second blocking plate 21b also includes a second driving mechanism disposed on the housing component 1 for driving the second blocking plate 21b to rotate horizontally. When it is necessary to block the camera lens, the second blocking plate 21b can rotate horizontally to the lens to block the camera lens. The second drive structure includes a slider 22b connected to the second blocking plate 21b. The slider 22b is arc-shaped and has several teeth along its extension direction. The second drive mechanism also includes a slide groove 23b disposed outside the housing assembly 1 and slidingly engaged with the slider 22b. The second drive mechanism also includes a second rotary drive component 24b fixed outside the housing assembly 1. The output end of the second rotary drive component 24b is connected to a third gear 25b, which meshes with the teeth on the slider 22b. The second rotary drive component 24b is fixed outside the housing assembly 1 and serves as the power source for the second drive mechanism. It can be a stepper motor, a micro servo motor, or other drive element with precise speed control capabilities. Its core function is to receive control signals from the circuit board in the control box 11, convert electrical energy into rotational mechanical energy, and transmit the power to the third gear 25b through the output end, thereby controlling the rotation speed and position of the second blocking plate 21b and ensuring the reliability and accuracy of the blocking action.

[0036] When a user triggers a privacy protection command, the circuit board in the control box 11 sends a rotation control signal to the second rotation drive 24b. After receiving the signal, the second rotation drive 24b starts and drives the third gear 25b at its output end to rotate. Since the third gear 25b meshes with the teeth on the slider 22b, the rotational power of the third gear 25b is transmitted to the slider 22b through the tooth surface contact, pushing the slider 22b to slide horizontally along the arc trajectory of the slide groove 23b towards the through groove. The slider 22b drives the second blocking plate 21b fixed thereto to rotate horizontally in sync. When the second blocking plate 21b rotates to a preset position that completely covers the through groove, the circuit board in the control box 11 controls the second rotation drive 24b to stop working, and the second blocking plate 21b remains in that position, thus blocking the camera lens. When the user needs to restore the camera's shooting function, the circuit board in the control box 11 sends a rotation control signal to the second rotation drive 24b; the second rotation drive 24b drives the third gear 25b to rotate, and through the meshing transmission of the gear and rack, pulls the slider 22b to slide horizontally away from the through groove along the arc trajectory of the slide groove 23b; the slider 22b drives the second blocking plate 21b to rotate horizontally in the opposite direction in sync; when the second blocking plate 21b rotates to the non-blocking position completely away from the through groove, the circuit board in the control box 11 controls the second rotation drive 24b to stop, and the camera lens resumes normal shooting through the through groove.

[0037] Reference Figures 1-2 As shown, the bottom of the housing assembly 1 is also provided with a fixing sleeve assembly 3 that can be fixed to the lower part of the camera. The fixing sleeve assembly 3 includes a first clamping sleeve 31 and a second clamping sleeve 32. The first clamping sleeve 31 and the second clamping sleeve 32 can be sleeved on the outside of the housing assembly 1. The upper ends of the first clamping sleeve 31 and the second clamping sleeve 32 are provided with annular grooves. The bottom of the housing assembly 1 is provided with an annular rail that cooperates with the annular grooves and can rotate in the annular grooves. The fixing sleeve assembly 3 is provided with an opening that corresponds to the lens at the lower part of the camera. The fixing sleeve assembly 3 is also provided with a second blocking assembly 4 that can block the lower lens. The fixing sleeve assembly 3 serves as a device to cover the camera. The core function of the lower fixing and support structure is to provide an installation base for the second shielding component 4 and to achieve rotational adaptation with the housing component 1. The first clamping sleeve 31 and the second clamping sleeve 32 are the main structures of the fixing sleeve component 3. They adopt a splicable design and can be fitted together on the outside of the housing component 1. By splicing, a complete ring clamping structure is formed to realize the assembly of the fixing sleeve component 3 and the housing component 1. The first clamping sleeve 31 and the second clamping sleeve 32 can be filled with elastic material, such as rubber, to make the clamping more stable. The first clamping sleeve 31 and the second clamping sleeve 32 can be fixed by magnetic attraction or bolts, or they can be glued together.

[0038] When installing the fixing sleeve assembly 3, firstly, the first clamping sleeve 31 and the second clamping sleeve 32 are spliced ​​and fitted onto the outside of the housing assembly 1, so that the annular rail at the bottom of the housing assembly 1 is embedded into the annular groove at the upper end of the first clamping sleeve 31 and the second clamping sleeve 32, completing the initial assembly of the fixing sleeve assembly 3 and the housing assembly 1; then, through the clamping force of the first clamping sleeve 31 and the second clamping sleeve 32, the fixing sleeve assembly 3 is stably fixed in the lower area of ​​the camera. At this time, the opening on the fixing sleeve assembly 3 is aligned with the lower lens of the camera, ensuring that the shooting channel of the lower lens is unobstructed. The second blocking assembly 4 moves towards the opening of the fixing sleeve assembly 3; when the second blocking assembly 4 completely covers the opening, the shooting path of the lower lens is blocked, achieving blocking; when shooting needs to be resumed, the second blocking assembly 4 moves in the opposite direction to disengage from the opening, and the lower lens resumes normal shooting through the opening.

[0039] Example 3: Refer to Figures 6-8 As shown, the second shielding assembly 4 includes a fixing ring 43a installed at the opening of the fixing sleeve assembly 3. A plurality of third shielding plates 41a are rotatably disposed in the fixing ring 43a and are evenly arranged along the fixing ring 43a. A guide post 41a1 is also provided on the third shielding plate 41a. A rotating member 42a is rotatably disposed on the outside of the fixing ring 43a. An arc-shaped groove 42a1 corresponding to the third shielding plate 41a is opened on the rotating member 42a. The guide post 41a1 can slide in the arc-shaped groove 42a1.

[0040] When the user triggers the lower lens privacy protection command, the external drive structure, such as a manually rotated knob or an electronically controlled drive motor, drives the rotating component 42a to rotate around the axis of the fixed ring 43a in a preset direction (such as clockwise). When the rotating component 42a rotates, each arc-shaped groove 42a1 on it moves synchronously in a circular motion with the rotating component 42a. The groove wall of the arc-shaped groove 42a1 generates a radially inward thrust on the guide post 41a1 embedded in the groove. Under the action of the thrust, the guide post 41a1 slides inward along the arc-shaped groove 42a1, while simultaneously driving the third shielding plate 41a fixed thereto to rotate around its own axis. The inner ring of the fixed ring 43a rotates; since all the third blocking pieces 41a are evenly distributed along the fixed ring 43a and the arc groove 42a1 has the same trajectory, all the third blocking pieces 41a rotate inward synchronously, gradually approach each other and splice together; when the rotating part 42a rotates to the preset angle, the guide post 41a1 slides to the inner limit position of the arc groove 42a1. At this time, all the third blocking pieces 41a are completely spliced ​​together to form a complete circular blocking surface, which completely covers the inner ring of the fixed ring 43a, i.e., the opening of the fixed sleeve assembly 3, blocking the shooting path of the lower lens and completing the blocking. When the user needs to restore the lower lens shooting function, the external drive structure drives the rotating part 42a to rotate in the opposite direction (such as counterclockwise) around the axis of the fixed ring 43a. When the rotating part 42a rotates in the opposite direction, the groove wall of the arc groove 42a1 generates a radially outward pulling force on the guide post 41a1. Under the action of the pulling force, the guide post 41a1 slides outward along the arc groove 42a1, driving the third blocking piece 41a to rotate around its own axis in the direction of the outer ring of the fixed ring 43a. All the third blocking pieces 41a rotate outward synchronously, gradually disengaging from the splicing state and retracting towards the inner ring edge of the fixed ring 43a. When the rotating part 42a rotates in the opposite direction to the preset angle, the guide post 41a1 slides to the outer limit position of the arc groove 42a1. At this time, all the third blocking pieces 41a completely retract to the inner ring edge of the fixed ring 43a, no longer blocking the opening, and the lower lens resumes normal shooting through the opening. If the rotating part 42a is driven by a motor, a gear ring can be installed on the outside of the rotating part 42a. The motor drives the gear to rotate the gear ring, which in turn drives the rotating part 42a to rotate. If a manual drive method is used, it is not necessary to install a gear ring.

[0041] Example 4: Refer to Figure 9As shown, the second shielding component 4 includes a fourth shielding plate 41b that can tilt and rotate and cover the lower lens of the camera. The fourth shielding plate 41b is a single-piece structure made of rigid material or composite material with a certain degree of toughness. Its shape and size need to be adapted to the shape and field of view of the lower lens of the camera. When the user has privacy protection needs, the fourth shielding plate 41b is covered outside the lower lens by tilting and rotating, physically blocking the visual path between the lens and the external environment. When it is necessary to resume shooting, the fourth shielding plate 41b is moved away from the lower lens by tilting and rotating in the opposite direction, freeing up the lens shooting space and ensuring that the lower lens can normally acquire external images. Compared with the multi-piece splicing structure of Embodiment 3, the fourth shielding plate 41b simplifies the shielding logic through the movement of a single piece, reducing assembly complexity and cost. The fourth shielding plate 41b can also be used manually or automatically. If the automatic method is used, a motor is needed to drive the shaft on the fourth shielding plate 41b to move, thereby causing the fourth shielding plate 41b to tilt and rotate.

[0042] Example 5: Refer to Figure 10 and Figure 11 As shown, the second shielding component 4 includes a guide groove 42c disposed at the opening of the fixed sleeve component 3 and a fifth shielding piece 41c slidably disposed in the guide groove 42c for shielding the lower lens of the camera.

[0043] The guide groove 42c is the motion guide and support structure for the fifth shielding plate 41c. It is integrally formed or fixedly installed at the opening of the fixed sleeve assembly 3. Its opening direction needs to be adapted to the arrangement direction of the lower lens of the camera. It is usually set along the radial or tangential direction of the opening of the fixed sleeve assembly 3 to ensure that the fifth shielding plate 41c can completely cover or detach from the opening when sliding. The cross-section of the guide groove 42c is U-shaped or I-shaped, and the groove width matches the thickness of the fifth shielding plate 41c. This ensures that the fifth shielding plate 41c can slide smoothly in the groove and avoids lateral displacement during the sliding process. The core function of the fifth shielding plate 41c is to guide the movement of the fifth shielding plate 41c through sliding. The current lens blocking and exposure switching: In the non-blocking state, the fifth blocking plate 41c does not cover the opening of the fixed sleeve assembly 3, and the lower lens can shoot normally through the opening; when the user triggers the blocking requirement, the fifth blocking plate 41c slides along the guide groove 42c to cover the opening, physically blocking the field of view of the lower lens; the fifth blocking plate 41c can be used manually or automatically. If the automatic method is used, several teeth need to be set on the outer surface of the fifth blocking plate 41c, and the fifth blocking plate 41c is driven to move by a motor and gears. Other methods can also be used, as long as the mechanism can drive the fifth blocking plate 41c to move.

[0044] Example 6: Refer to Figure 12As shown, the second shielding component 4 includes a sixth shielding piece 41d that is rotatably disposed at the opening of the fixed sleeve component 3. The sixth shielding piece 41d can rotate up and down to shield the lower lens of the camera.

[0045] The sixth obstruction plate 41d is a single, rigid sheet structure made of high-strength plastic or metal sheet. Its shape must be adapted to the opening shape of the fixing sleeve assembly 3 and the field of view of the lower lens of the camera. It is usually designed as a circle, an ellipse, or an irregular shape that matches the opening, ensuring that in the obstructed state, the coverage area of ​​the sixth obstruction plate 41d completely exceeds the effective shooting area of ​​the lower lens, with no gaps in the field of view. In the unobstructed state, it can be rotated to completely avoid the lens's field of view without affecting shooting. When the user has privacy protection needs, the sixth obstruction plate 41d rotates downward to cover the opening of the fixing sleeve assembly 3, physically blocking the visual path between the lower lens and the external environment. When shooting needs to be resumed, the sixth obstruction plate 41d rotates upward to disengage from the opening, freeing up the lens's shooting space and ensuring that the lower lens can normally acquire images through the opening. The sixth shielding plate 41d can be operated manually or automatically. In automatic mode, the rotating shaft on the sixth shielding plate 41d can be fixed to the output end of the micro geared motor or servo motor through a coupling. Other mechanisms can also be used, as long as they can drive the sixth shielding plate 41d to rotate.
