[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 10 The present embodiment provides a lens privacy cover mechanism, comprising 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] Buffer components 12 are installed at both ends of the shell 1. The buffer components 12 are used to detachably abut against the privacy cover 2 and can be deformed under the extrusion 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 of this embodiment is as follows:

[0037] When the privacy cover 2 slides along the guide rod 11, the privacy cover 2 will contact the buffer assembly 12 when it slides to the extreme positions at both ends. The buffer assembly 12 is deformed under the extrusion of the privacy cover 2, and the speed of the privacy cover 2 is reduced, so that the speed of the privacy cover 2 is gradually reduced. Compared with the method in the prior art that the privacy cover 2 stops instantly by collision, the present embodiment provides the buffer assembly 12, so that the privacy cover 2 can slow down smoothly, reduce noise, and avoid damage and loosening of the privacy cover 2 and the transmission parts due to collision. In addition, when the housing 1 vibrates under the influence of external noise or vibration, the buffer assembly 12 can reduce the consistency of the movement of the housing 1 and the privacy cover 2 by its own deformation, thereby avoiding resonance.

[0038] As a possible example, in this embodiment, the privacy cover 2 is provided with a foot, and the guide rod 11 passes through the foot. The housing 1 is provided with a groove for accommodating the foot, and the foot translates in the groove. Both ends of the privacy cover 2 are provided with a foot, and the buffer assembly 12 is used to detachably abut against the foot.

[0039] By extending the support foot into the groove, the distance between the privacy cover 2 and the housing 1 can be reduced, thereby reducing the overall volume and improving compactness. Exemplarily, there are four guide rods 11, each guide rod 11 corresponds to a support foot, and the four support feet are respectively arranged at the four corners of the privacy cover 2. The two guide rods 11 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, and the spring is sleeved on the outer side of the guide rod 11.

[0041] That is, the buffer component 12 in this embodiment is an elastic buffer component 12, and as the compression amount of the spring increases, its elastic resistance to the privacy cover 2 gradually increases. Compared with elastic parts such as springs and rubber pads, the spring has a larger deformation space, so that the privacy cover 2 has a larger buffer distance.

[0042] As a possible example, in this embodiment, the buffer assembly 12 further includes a slider and a stopper, the guide rod 11 passes through the slider, and the two ends of the spring are respectively connected to the groove and the stopper. The stopper is fixed to the side of the slider away from the spring, and is used to detachably abut 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 limiting the slider in one direction through the block, pressure is applied to the spring when the slider does not contact the support foot. The spring therefore has a certain amount of pre-compression, thereby increasing the elastic resistance provided by the spring, thereby increasing 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 shell 1 and is deformed under the extrusion of the guide rod 11 to apply pre-pressure to the guide rod 11 .

[0045] It should be noted that, in order to facilitate 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, which will cause the guide rod 11 to shake in the through hole and generate noise. In this embodiment, the elastic pad 15 applies a thrust to the guide rod 11, so that the guide rod 11 is always in sliding contact with the part of the through hole close to the housing 1, and the guide rod 11 will not shake in the through hole, thereby reducing noise and improving the stability of the privacy cover 2.

[0046] As a possible example, in the present embodiment, the elastic pad 15 is a wear-resistant tape. More specifically, the type of the wear-resistant tape can be Teflon wear-resistant tape. Depending on actual needs, those skilled in the art can also select 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 the circuit board 13 are fixed to the housing 1, and the circuit board 13 is electrically connected to the motor 3 to control the action of the motor 3. The motor 3 is used to drive the screw 8 to rotate, and the screw 8 is threadedly connected to the nut 7, and the screw 8 is rotatably mounted on the housing 1. The nut 7 has a connecting end, and the connecting end is connected to the privacy cover 2, and is used to push the privacy cover 2 along the length direction of the guide rod 11. The housing 1 is provided with a through hole for the connecting end to pass through.

[0048] Compared with other types of linear drive components such as electric push rods and gear rack mechanisms, this embodiment uses a threaded connection between the screw rod 8 and the nut 7 to achieve transmission, and its control accuracy is higher. When the motor 3 drives the screw rod 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 rod 8, but translates along the length direction of the screw rod 8, thereby driving the privacy cover 2 to translate synchronously.

[0049] As a possible example, in this embodiment, the linear drive assembly further includes a vibration-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 influence of the motor 3 on the stability of the housing 1 when the motor 3 is working.

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

[0052] Through the transmission cooperation between the small gear 4 and the large gear 5, the rotation speed of the screw 8 can be reduced, thereby improving the control accuracy of the position of the nut 7.

[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 cooperates with the axial hole of the bare rod section of the screw 8 to support the screw 8. The bearing 10 cover 9 presses and fixes the bearing 10 on the housing 1. The bearing 10 cover 9 is fixed to the housing 1 by screws to facilitate the 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 is provided with a mounting hole, and the glass 14 is fixed at the mounting hole. When the glass 14 is facing the shooting position on the housing 1, it is a normal shooting state. When the cover body is facing the shooting position on the housing 1, it is a stop shooting state.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
