[0009] Preferably, the buffer assembly further includes a slider and a stop, the guide rod passes through the slider, and the two ends of the spring are respectively connected to the groove and the stop; the stop is fixed to the side of the slider away from the spring and is used to detachably abut against the slider to limit the initial compression of the spring to a preset value; the slider is used to contact the support foot.

[0010] Preferably, the privacy cover is connected to an elastic pad located on the side of the guide rod away from the housing, and deforms under the pressure of the guide rod to apply pre-pressure to the guide rod.

[0011] Preferably, the elastic pad is abrasion-resistant tape.

[0031] 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.

[0032] The purpose of this invention is to provide a lens privacy cover mechanism that makes the movement of the privacy cover more stable.

[0033] 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.

[0034] Reference Figures 1-10 This embodiment provides a lens privacy cover mechanism, including a housing 1, a privacy cover 2, a guide rod 11, a linear drive assembly, and a buffer assembly 12. The guide rod 11 is connected to the housing 1 and passes through the privacy cover 2. The linear drive assembly is mounted on the housing 1 and is used to drive the privacy cover 2 to slide along the guide rod 11.

[0035] Both ends of the housing 1 are equipped with buffer components 12. The buffer components 12 are used to detachably abut against the privacy cover 2 and can deform under the pressure of the privacy cover 2 to buffer the privacy cover 2 and suppress resonance during the operation of the conference machine speaker.

[0036] The working principle of the lens privacy cover mechanism in this embodiment is as follows:

[0037] As the privacy cover 2 slides along the guide rod 11, it contacts the buffer assembly 12 near its extreme positions. The buffer assembly 12 deforms under the pressure of the privacy cover 2, simultaneously reducing its speed and achieving a gradual decrease in speed. Compared to the prior art where the privacy cover 2 stops instantly upon impact, this embodiment, by incorporating the buffer assembly 12, allows the privacy cover 2 to decelerate smoothly, reducing noise and preventing damage or loosening caused by collisions between the privacy cover 2 and the transmission components. Furthermore, when the housing 1 vibrates under external noise or vibration, the buffer assembly 12 can deform itself to reduce the consistency of movement between the housing 1 and the privacy cover 2, thereby preventing resonance.

[0038] As a possible example, in this embodiment, the privacy cover 2 is provided with feet, through which the guide rod 11 passes. The housing 1 is provided with a groove for accommodating the feet, within which the feet translate. Feet are provided at both ends of the privacy cover 2, and a buffer assembly 12 is used for detachable contact with the feet.

[0039] By inserting the support legs into the grooves, the distance between the privacy cover 2 and the housing 1 can be reduced, thereby reducing the overall volume and improving compactness. For example, there are four guide rods 11, each corresponding to one support leg, with the four legs positioned at the four corners of the privacy cover 2. Two guide rods 11 located on the same side of the privacy cover 2 are collinear.

[0040] As a possible example, in this embodiment, the buffer assembly 12 includes a spring that is sleeved on the outside of the guide rod 11.

[0041] That is, the buffer component 12 in this embodiment is an elastic buffer component 12. As the spring compression increases, its elastic resistance to the privacy cover 2 gradually increases. Compared with elastic elements such as spring sheets and rubber pads, the spring has a larger deformation space, giving the privacy cover 2 a larger buffer distance.

[0042] As a possible example, in this embodiment, the buffer assembly 12 further includes a slider and a stop, with the guide rod 11 passing through the slider, and the two ends of the spring connected to the groove and the stop, respectively. The stop is fixed to the side of the slider away from the spring and is used to detachably abut against the slider to limit the initial compression of the spring to a preset value. The slider is used to contact the support foot.

[0043] By using a stop block to unidirectionally limit the slider, pressure is applied to the spring before the slider contacts the support foot. As a result, the spring has a certain amount of pre-compression, which increases the elastic resistance provided by the spring and thus improves the deceleration effect on the privacy cover 2.

[0044] As a possible example, in this embodiment, the privacy cover 2 is connected to an elastic pad 15, which is located on the side of the guide rod 11 away from the housing 1 and deforms under the pressure of the guide rod 11 to apply pre-pressure to the guide rod 11.

[0045] It should be noted that, for ease of assembly, the diameter of the guide rod 11 is usually smaller than the diameter of the through hole on the support leg through which the guide rod 11 passes. This would cause the guide rod 11 to wobble within the through hole, generating noise. In this embodiment, the elastic pad 15 applies a pushing force to the guide rod 11, ensuring that the guide rod 11 always slides in contact with the portion of the through hole closest to the housing 1. The guide rod 11 will not wobble within the through hole, thereby reducing noise and improving the stability of the privacy cover 2.

[0046] As one possible example, in this embodiment, the elastic pad 15 is an abrasion-resistant tape. More specifically, the type of abrasion-resistant tape can be Teflon abrasion-resistant tape. Depending on the actual needs, those skilled in the art can also choose other types of elastic pads 15.

[0047] As a possible example, in this embodiment, the linear drive assembly includes a motor 3, a screw 8, a nut 7, and a circuit board 13. The motor 3 and circuit board 13 are fixed to the housing 1, and the circuit board 13 is electrically connected to the motor 3 to control the movement of the motor 3. The motor 3 drives the screw 8 to rotate, and the screw 8 is threadedly connected to the nut 7, rotatably mounted on the housing 1. The nut 7 has a connecting end that connects to a privacy cover 2, used to push the privacy cover 2 along the length of the guide rod 11. The housing 1 has a through hole through which the connecting end passes.

[0048] Compared to other types of linear drive components such as electric actuators and rack and pinion mechanisms, this embodiment uses a threaded connection between the screw 8 and the nut 7 to achieve transmission, resulting in higher control precision. When the motor 3 drives the screw 8 to rotate, since the connecting section of the nut 7 is connected to the privacy cover 2, the nut 7 does not rotate with the screw 8, but instead translates along the length of the screw 8, thereby causing the privacy cover 2 to translate synchronously.

[0049] As a possible example, in this embodiment, the linear drive assembly also includes a damping pad 6, which is clamped between the motor 3 and the housing 1.

[0050] The vibration damping pad 6 is used to absorb the vibration of the motor 3 and reduce the impact of the motor 3 on the stability of the housing 1 when it is working.

[0051] As a possible example, in this embodiment, the linear drive assembly further includes a pinion 4 and a gear 5. The pinion 4 is mounted on the output shaft of the motor 3, and the gear 5 is mounted on the screw 8. The pinion 4 meshes with the gear 5.

[0052] By using the transmission between the pinion 4 and the gear 5, the rotational speed of the screw 8 can be reduced, thereby improving the control accuracy of the nut 7 position.

[0053] As a possible example, in this embodiment, the linear drive assembly further includes a bearing 10 and a bearing 10 cover 9. The inner ring of the bearing 10 mates with the bore of the smooth section of the screw 8 to support the screw 8. The bearing 10 cover 9 presses the bearing 10 firmly onto the housing 1. The bearing 10 cover 9 is fixed to the housing 1 by screws to facilitate quick installation and removal of the bearing 10 cover 9.

[0054] As a possible example, in this embodiment, the privacy cover 2 includes a cover body and a glass 14. The cover body has mounting holes, and the glass 14 is fixed to the mounting holes. When the glass 14 is facing the shooting position on the housing 1, it is in normal shooting mode. When the cover body is facing the shooting position on the housing 1, it is in stopped shooting mode.

[0055] 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.
