[0010] In some embodiments, an internal gear ring is provided on the side of the second gear portion away from the first gear portion, and a drive gear is provided on the output shaft of the drive device, the drive gear meshing with the internal gear ring for transmission.

[0011] In some embodiments, a control board is provided inside the front housing, and one end of the first rotating shaft is disposed opposite to one side of the control board; a magnet is provided at the shaft end of the first rotating shaft near the control board, and a magnetic encoder is provided on the side of the control board near the first rotating shaft, with the magnetic encoder being disposed opposite to and spaced apart from the magnet.

[0012] In some embodiments, the outer peripheral wall of the second gear portion is provided with a first protrusion, and the interior of the front housing is provided with an elastic limiting member.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The purpose of this invention is to provide a privacy cover component and a camera device to solve the problems existing in the prior art, which can simulate the opening and closing effect of the eyes, improve the user experience, and enhance the value of use.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model provides a privacy cover component, such as Figures 1 to 10As shown, it includes a front housing 1, a first privacy cover 2, a second privacy cover 3, an end face meshing gear 6, and a drive device 7; wherein, the front housing 1 is provided with a through hole, and the first privacy cover 2 and the second privacy cover 3 are rotatably connected to the inner wall of the front housing 1, and the first privacy cover 2 and the second privacy cover 3 can rotate in opposite directions to close or open the through hole.

[0037] One end of the first privacy cover 2 is a first hinge end, and the other end is provided with a first gear part 21; one end of the second privacy cover 3 is a second hinge end, and the other end is provided with a second gear part 31; both the first hinge end and the second hinge end are rotatably connected to the first rotating shaft, and both the first gear part 21 and the second gear part 31 are rotatably connected to the second rotating shaft 4.

[0038] See Figure 3 As shown, the side of the first gear section 21 closest to the second gear section 31 is a first end face gear, and the side of the second gear section 31 closest to the first gear section 21 is a second end face gear. The first end face gear and the second end face gear are arranged parallel to each other and opposite to each other. The end face meshing gear 6 is located between the first end face gear and the second end face gear, and the end face meshing gear 6 meshes with both the first end face gear and the second end face gear for transmission.

[0039] The drive device 7 is connected to the second gear part 31 for transmission, and the drive device 7 can drive the second end face gear to rotate. The second end face gear can drive the first end face gear to rotate through the end face meshing gear 6. The rotation directions of the first end face gear and the second end face gear are opposite. Thus, the first privacy cover 2 and the second privacy cover 3 can rotate in opposite directions to open or close.

[0040] It should be noted that the end face meshing gear 6 is a face tooth pairing gear. Those skilled in the art can specifically set the number of end face meshing gears 6. For example, two end face meshing gears 6 can be set, and the rotation axes of the two end face meshing gears 6 are on a straight line.

[0041] In some implementations, see further reference. Figure 1 The end-face meshing gear 6 is rotatably connected to the third rotating shaft 5, and the axis of the third rotating shaft 5 is perpendicular to and intersects the axis of the second rotating shaft 4; for example Figure 5 As shown, one end of the third rotating shaft 5 is connected to the second rotating shaft 4 in a vertical direction; as Figure 3 As shown, an elastic retaining ring 14 is provided at one end of the third rotating shaft 5.

[0042] In some implementations, such as Figure 10 As shown, an internal gear ring is provided on the side of the second gear section 31 away from the first gear section 21, and a drive gear 8 is provided on the output shaft of the drive device 7. The drive gear 8 meshes with the internal gear ring for transmission. Specifically, the drive gear 8 is sleeved on the output shaft of the drive device 7 and the two are connected by a key.

[0043] The drive device 7 of this utility model can drive the internal gear ring to rotate through the drive gear 8. The internal gear ring rotates synchronously with the second end face gear. The second end face gear can drive the first end face gear to rotate through the end face meshing gear 6. The rotation directions of the first end face gear and the second end face gear are opposite.

[0044] In some implementations, such as Figure 9 As shown, a control board 9 is provided inside the front housing 1, and one end of the first rotating shaft is disposed opposite to one side of the control board 9; a magnet 10 is provided at the shaft end of the first rotating shaft near the control board 9, and a magnetic encoder 11 is provided on the side of the control board 9 near the first rotating shaft. The magnetic encoder 11 is disposed opposite to the magnet 10 and spaced apart.

[0045] The magnetic encoder 11 of this invention detects the rotation angle and speed of the privacy cover through the magnet 10 and feeds it back to the system, so that the system can accurately control the opening or closing of the privacy cover according to the detected values.

[0046] In some embodiments, the magnetic encoder 11 of this invention is an angle sensor, and the magnet 10 is a neodymium iron boron magnet. It is understood that the magnetic encoder 11 of this invention can also be other types of sensors, and the magnet 10 can also be made of other materials; this invention does not impose any specific limitations on these aspects.

[0047] In some implementations, such as Figure 10 As shown, the outer peripheral wall of the second gear part 31 is provided with a first protrusion 12, and the interior of the front housing 1 is provided with an elastic limiting member. One end of the elastic limiting member is connected and fixed to the inner wall of the front housing 1, and the other end is a second protrusion 13, which is an elastic protrusion.

[0048] The second protrusion 13 abuts against and presses against the outer peripheral wall of the second gear part 31. During the rotation of the second gear part 31, the second protrusion 13 always presses against the outer peripheral wall of the second gear part 31. That is, the elastic limiting member can apply a damping force to the rotation of the second gear part 31 through the second protrusion 13. This damping force can make the first privacy cover 2 and the second privacy cover 3 maintain considerable stability and will not close and block the lens due to normal vibration. That is, the second privacy cover 3 needs to overcome the damping force to rotate.

[0049] Furthermore, when the first privacy cover 2 and the second privacy cover 3 rotate relative to each other to the closed state, the first protrusion 12 can rotate past the second protrusion 13. At this time, the second protrusion 13 can limit the rotation of the first protrusion 12. That is, the second protrusion 13 and the first protrusion 12 cooperate to limit the rotation of the second gear part 31. At the same time, the elastic force of the elastic limiting member can press the outer peripheral wall of the second gear part 31, so that the first privacy cover 2 and the second privacy cover 3 are tightly closed and no gaps will be generated due to vibration.

[0050] When the first privacy cover 2 and the second privacy cover 3 need to be opened, the drive device 7 needs to overcome the elastic force of the elastic limiting member and drive the first protrusion 12 to rotate past the second protrusion 13 and continue to rotate.

[0051] It should be noted that by setting the first protrusion 12 and the second protrusion 13, the movement of the first privacy cover 2 and the second privacy cover 3 maintains relative stability. Moreover, the two privacy covers are driven to close by elastic force when closed, that is, they can be self-locked by the elastic limiting member. Thus, the driving device 7 can be powered off after closing or opening, reducing system power and extending service life.

[0052] In some embodiments, the driving device 7 of this invention is a motor.

[0053] In some embodiments, the first privacy cover 2 has a first partial spherical structure, and the second privacy cover 3 has a second partial spherical structure. When the first privacy cover 2 and the second privacy cover 3 are in the closed state, one end of the first partial spherical structure and the second partial spherical structure abuts against each other to close the through hole on the front housing 1, and at least a portion of the first partial spherical structure and the second partial spherical structure protrudes beyond the front housing 1.

[0054] The first privacy cover 2 and the second privacy cover 3 of this utility model rotate relative to each other to open or close, a process similar to opening and closing one's eyes.

[0055] When using the privacy cover assembly of this utility model:

[0056] The output shaft of the motor drives the drive gear 8 to rotate, and the drive gear 8 drives the internal gear ring of the second gear section 31 to rotate. The second end face gear and the internal gear ring rotate synchronously around the second rotating shaft 4. The second end face gear drives the end face meshing gear 6 to rotate around the third rotating shaft 5. Then the end face meshing gear 6 drives the first end face gear to rotate, and the rotation direction of the first end face gear is opposite to the rotation direction of the second end face gear. This causes the first privacy cover 2 and the second privacy cover 3 to rotate in opposite directions, simulating the opening and closing effect of the eyes. The structure is compact, simple and low cost.

[0057] The privacy cover assembly of this utility model is small in size, equipped with a micro motor, and can be made within a space of 77×41×52mm. Two spherical privacy covers can move towards each other without interfering with each other using only one motor. The movement stop position is damped, which has good stability and shock resistance and prevents gaps. It is also low in cost.

[0058] This utility model also provides a camera device, including the aforementioned privacy cover assembly.

[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
