Technical Field

[0001] This utility model relates to the field of photography, specifically to a shielding component for an imaging device. Background Technology

[0002] Cameras are widely used in conferencing systems, security, and automotive applications, and with users increasingly concerned about privacy, most technologies use manual shutters to prevent unauthorized remote access or unauthorized privacy leaks. Users can manually slide the shutter in front of the camera lens for physical blocking. However, this is inconvenient in scenarios involving frequent camera switching, and the shutter can easily rub against the housing, causing uneven sliding and inadequate blocking, resulting in a poor user experience.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] Therefore, this embodiment provides a shielding member for an imaging device. The shielding member for the imaging device can automatically achieve shielding.

[0035] Please see Figure 1 and Figure 6 A shielding component for an imaging device includes: a fixing component 10, a driving mechanism 30, and a shielding component 40.

[0036] The fixing member 10 has a through hole 11, the driving mechanism 30 is disposed on the fixing member 10, and the blocking member 40 is disposed on the driving mechanism 30. The driving mechanism 30 can drive the blocking member 40 to move along the length direction of the fixing member 10 so that the blocking member 40 blocks or opens the through hole 11.

[0037] A through hole 11 is provided on the fixing member 10, and a camera 20 is installed inside the fixing member 10. The camera 20 can take pictures through the through hole 11. A driving mechanism 30 is provided on the fixing member 10, and a blocking member 40 is provided on the driving mechanism 30. The blocking member 40 can cover the through hole 11 and can be made of a lightweight light-blocking material. The blocking member 40 is driven by the driving mechanism 30 to cover the through hole 11, so that the light from the camera 20 can be completely blocked by the blocking member, thus achieving physical blocking of the camera 20. When the blocking member 40 moves out of the through hole 11 area, light can enter through the through hole 11, and the camera 20 can take pictures normally, thus improving the convenience of the camera 20 taking pictures. By configuring the shielding part 41 and the driving part 42, the shielding part 40 is positioned slightly above the fixing part 10, preventing wear between the shielding part 40 and the fixing part 10, which could cause uneven sliding or incomplete shielding. When the shielding part 40 moves out of the through hole 11 area, light can enter through the through hole 11, allowing the camera 20 to take pictures normally, thus improving the ease of shooting with the camera 20. In addition, the innovative integration of the motor fixing frame and the camera 20 housing achieves a miniaturized design, reducing the number of components and the space occupied, facilitating installation.

[0038] Please see Figure 1 and Figure 6 In some embodiments, the fixing member 10 is provided with a cavity, and a camera 20 is disposed in the cavity, wherein the optical axis of the camera 20 is collinear with the axis of the through hole 11.

[0039] Understandably, the inside of the fixing member 10 is set as a cavity, and the camera 20 is fixedly mounted on the fixing member 10. A through hole 11 is provided on the fixing member 10, and the optical axis of the camera 20 is collinear with the axis of the through hole 11. In this way, the field of view of the camera 20 is not affected by the fixing member 10 when shooting, thus improving the shooting quality of the camera 20.

[0040] Please see Figure 2-3 In some embodiments, the fastener 10 includes: a mounting portion 12, a first recessed portion 13, and a second recessed portion 14;

[0041] The first recess 13 and the second recess 14 are spaced apart on both sides of the fixing member 10, and the driving member 31 is disposed close to the first recess 13 or the second recess 14.

[0042] Understandably, the fixing member 10 includes: a mounting portion 12, a first recessed portion 13, and a second recessed portion 14. The mounting portion 12 refers to the area on the fixing member 10 used for mounting the driving member 31. The first recessed portion 13 refers to a groove structure provided on one side of the fixing member 10, and the second recessed portion 14 refers to a groove structure provided on the other side of the fixing member 10. The first recessed portion 13 and the second recessed portion 14 are arranged opposite to each other, so that the first recessed portion 13 and the second recessed portion 14 are distributed on both sides of the fixing member 10, thereby avoiding interference between the lead screw and the guide member during movement and reducing the impact of mechanical vibration on the stability of the camera 20. The recessed portions can be embedded inside the fixing member 10, reducing the overall structural volume and making it suitable for space-constrained applications.

[0043] Please see Figure 2 and Figure 3 In some embodiments, the drive mechanism 30 includes: a drive member 31 and a lead screw 32;

[0044] The driving component 31 is connected to the lead screw 32, and the lead screw 32 is connected to the blocking component 40. When the driving component 31 rotates, it drives the lead screw 32 to rotate, thereby driving the blocking component 40 to move.

[0045] Understandably, the drive mechanism 30 includes a drive member 31 and a lead screw 32. The lead screw 32 and the drive member 31 are directly connected. When the drive member 31 is energized and rotates, it can drive the lead screw 32 to rotate synchronously. A slider is fixedly installed on the blocking member 40. The slider has a built-in thread and is adapted to the lead screw 32. In this way, when the lead screw 32 rotates, it can drive the blocking member 40 to move in a straight line so that the blocking member 40 covers the through hole 11 or moves away from the through hole 11. For example, when the drive member 31 rotates clockwise, the blocking member 40 moves towards the through hole 11 to close the through hole 11; when the drive member 31 rotates counterclockwise, the blocking member 40 moves away from the through hole 11 to open the through hole 11, thereby enabling the camera 20 to take pictures.

[0046] Please see Figure 2 In some embodiments, the drive mechanism 30 further includes: a first gear 33 and a second gear 34;

[0047] The driving component 31 is connected to the first gear 33, the first gear 33 meshes with the second gear 34, the second gear 34 is connected to the lead screw 32, and the lead screw 32 is connected to the blocking component 40 to drive the blocking component 40 to move.

[0048] Understandably, the drive mechanism 30 also includes a first gear 33 and a second gear 34. The first gear 33 is connected to the drive member 31, and the second gear 34 meshes with the first gear 33. The second gear 34 is also fixedly connected to the lead screw 32. Thus, when the drive member 31 rotates, it can drive the first gear 33 and the second gear 34 to rotate. The rotation of the second gear 34 can drive the lead screw 32 to rotate, and the rotation of the lead screw 32 can drive the baffle to move, thereby achieving the displacement of the baffle 40. The first gear 33 and the second gear 34 can improve the driving efficiency and the accuracy of the driving positioning, while also reducing transmission noise and achieving the goal of improving the user experience.

[0049] In this embodiment, both the first gear 33 and the second gear 34 can be configured as spur gears to drive the baffle plate.

[0050] Please see Figure 2 In some embodiments, the first gear 33 and the second gear 34 are both helical gears, and the axis of the driving member 31 is perpendicular to the axis of the lead screw 32.

[0051] Understandably, the first gear 33 and the second gear 34 are set as helical gears. In order to save space, the axis of the rotating shaft of the driving member 31 is set perpendicular to the axis of the lead screw 32. That is, the driving member 31 is set on one side of the lead screw 32. By setting the first gear 33 and the second gear 34 as helical gears, the reversal can be achieved, so that the driving member 31 set on one side can drive the lead screw 32 to rotate. The driving method is that the driving member 31 drives the first helical gear (i.e., the first gear 33) to rotate. The first helical gear meshes with the second helical gear (i.e., the second gear 34) to drive the second helical gear to rotate. The second helical gear is connected to the lead screw 32, thereby driving the lead screw to rotate, so as to realize the driving of the baffle.

[0052] Please see Figure 4 In some embodiments, it also includes: a guide rod 35;

[0053] The shielding member 40 is slidably connected to the guide rod 35, and the guide rod 35 is used to provide guidance when the shielding member 40 moves.

[0054] Understandably, the guide rod 35 refers to a rod-shaped structure extending along the length of the fixing member 10. A smooth coating can be applied to its surface to reduce frictional resistance. Its function is to provide linear constraint on the movement path of the blocking member 40, preventing deviation or swaying. The blocking member 40 is partially sleeved on the guide rod 35. When the drive mechanism 30 transmits rotational motion through the lead screw 32, the blocking member 40 generates linear displacement under the threaded drive of the lead screw 32. At this time, the guide rod 35 restricts the movement direction of the blocking member 40 through a sliding connection, causing it to move only along the length of the fixing member 10.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the drive member 31 is disposed in the mounting portion 12, the lead screw 32 is disposed in the first recessed portion 13, and the guide rod 35 is disposed in the second recessed portion 14.

[0056] Understandably, the drive component 31 is located in the mounting portion 12. A lead screw is located in the first recess 13, and a guide rod 35 is located in the second recess 14. When the drive component 31 is activated, the lead screw 32 rotates within the limiting groove of the first recess 13, causing the blocking component 40 to move along the length of the guide rod 35. The guide rod 35 is embedded in the positioning groove of the second recess 14, forming a clearance fit with the sliding component of the blocking component 40, continuously providing linear guiding constraint during the movement of the blocking component 40. By providing the first recess 13 and the second recess 14 on the fixing component 10, the structure of the fixing component 10 becomes more compact, effectively reducing mutual interference between moving components.

[0057] Please see Figure 5 In some embodiments, the blocking member 40 includes: a blocking part 41 and a driving part 42;

[0058] The blocking part 41 and the driving part 42 are connected in sequence. The blocking part 41 is used to block the through hole 11, and the driving part 42 is connected to the guide rod 35 and the lead screw 32.

[0059] Understandably, the blocking part 41 and the driving part 42 are integrally formed or mechanically connected to form a single structure. The driving part 42 is provided on both sides of the blocking part 41, one of which engages with the lead screw 32, and the other is connected to the guide rod 35. Thus, when the lead screw 32 rotates, the threaded hole or slider inside the driving part 42 engages with the threaded connection of the lead screw 32, converting the rotational motion into linear displacement, driving the blocking part 41 to move along the guide rod 35. The guide rod 35 engages with the sliding sleeve of the driving part 42 to restrict the direction of movement, ensuring that the blocking part 41 moves precisely along the length of the fixing member 10.

[0060] Please see Figure 3 and Figure 4 In some embodiments, the drive portion 42 is accommodated in the first recess 13 and the second recess 14.

[0061] Understandably, both sides of the shielding member 40 are provided with driving parts 42, which extend into the first recess 13 and the second recess 14. In this way, the driving member 31 can drive the shielding member 40 to move along the lead screw 32 and the guide rod 35 in a relatively stable manner, thereby improving the stability of the shielding member 40 during the movement.

[0062] Please see Figure 4In some embodiments, it also includes: an upper housing 50 and a lower housing 51;

[0063] The upper housing 50 and the lower housing 51 are detachably connected, and the upper housing 50 and the lower housing 51 form a receiving cavity 52. ​​The fixing member 10 and the driving mechanism 30 are both disposed in the receiving cavity 52.

[0064] The upper housing 50 is provided with a light-transmitting hole 53, and the light-transmitting hole 53 is collinear with the axis of the through hole 11.

[0065] Understandably, the upper housing 50 refers to the structural component covering the upper part of the equipment, which together with the lower housing 51 forms a closed accommodating cavity 52. ​​The upper housing 50 and the lower housing 51 are connected in a detachable manner. Specifically, the upper housing 50 and the lower housing 51 are detachably assembled through structures such as snap-fit ​​and bolt connection. When it is necessary to install or replace parts, the relevant parts set inside the housing can be disassembled by separating the upper housing 50.

[0066] Understandably, the upper housing 50 is provided with a light-transmitting hole 53, the axis of which is collinear with the axis of the through hole 11. This allows the camera 20 to capture images through the light-transmitting hole 53. The diameter of the light-transmitting hole 53 is larger than the diameter of the through hole 11, so that the camera 20 can have a larger shooting range.

[0067] Please see Figure 4 In some implementations, it also includes: a PCB board 60;

[0068] The PCB board 60 is disposed within the fixing member 10, and the PCB board 60 is electrically connected to the camera 20.

[0069] Understandably, the PCB board 60 is located inside the fixture 10 and at the bottom of the fixture 10. The PCB board 60 can be fixed inside the fixture 10 by screws or other fixing methods. The camera 20 is located on the PCB board 60. The camera 20 can be connected to the PCB board 60 through a ribbon cable to avoid poor contact caused by vibration, thereby reducing the probability of camera 20 failure.
