It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described are capable of operation in sequences other than those illustrated or otherwise described herein.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

For convenience of understanding and explanation, the variable aperture module, the periscopic camera and the electronic device provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 7.

Please refer to fig. 1, which is a schematic structural diagram of an iris diaphragm module according to an embodiment of the present disclosure. The iris diaphragm module 100 includes a light shielding blade 101 and a lead screw nut transmission mechanism 102. The shading blade 101 is connected with a lead screw nut transmission mechanism 102, and the lead screw nut transmission mechanism 102 is used for controlling the shading blade 101 to do reciprocating linear motion. The advantage of this arrangement is that the screw nut transmission mechanism 102 can convert its own rotation motion into linear motion of the shading vane 101, so as to control the shading vane 101, and has the advantages of simple structure, low manufacturing cost, accurate motion and high reliability.

Optionally, as shown in fig. 2, which is a partially enlarged schematic view of the iris diaphragm module of fig. 1 in the embodiment of the present application. The screw nut transmission mechanism 102 includes a motor 1021, a nut slider 1022 and a screw 1023, the shading blade 101 is fixed on the nut slider 1022, the screw 1023 penetrates through the nut slider 1022, and the motor 1021 is used for driving the screw 1023 to rotate. At this time, the screw nut transmission mechanism 102 belongs to a sliding screw nut mechanism.

Alternatively, the connection part of the screw 1023 and the nut slide 1022 may also be an arc-shaped spiral raceway filled with balls. At this time, the screw nut transmission mechanism 102 belongs to a ball screw nut mechanism. Because rolling friction exists between the ball and the nut sliding block 1022 and the lead screw 1023 during transmission, the positioning mechanism has the advantages of high transmission efficiency and more accurate positioning precision.

In actual use, the transmission form of the lead screw nut transmission mechanism 102 is determined according to the relative movement of the nut sliding block 1022 and the lead screw 1023. For example, the lead screw 1023 is rotated, and the nut runner 1022 is moved; alternatively, the nut runner 1022 is fixed, and the lead screw 1023 rotates and moves.

Optionally, the lead screw nut transmission mechanism 102 further includes a motor support 1024, and the motor support 1024 is provided with a positioning hole 1025 for positioning with a camera support on the electronic device, so as to facilitate assembly.

The operation principle of the iris diaphragm module 100 in the embodiment of the present invention will be described below, and it is assumed that the initial state of the periscopic camera 103 is a large diaphragm in fig. 3, and the light-shielding blade 101 does not need to shield the periscopic camera 103, where the dotted line indicates the field of view of the periscopic camera 103. When the size of the aperture needs to be adjusted, the motor 1021 drives the lead screw 1023 to rotate, and the lead screw 1023 drives the nut slider 1022 and the shading blade 101 on the nut slider 1022 to do linear motion together. Until the periscopic camera 103 is completely blocked by the light blocking blade 101 as shown in fig. 4, the periscopic camera 103 is switched from the previous large aperture state to the small aperture state, and the aperture size of the periscopic camera is switched. When it is necessary to switch from the small aperture state shown in fig. 4 to the large aperture state shown in fig. 3, the rotation direction of the motor 1021 is changed so that the light-shielding blade 101 is moved in the opposite direction.

The iris diaphragm module that this application embodiment provided, this iris diaphragm module include shading blade and screw nut drive mechanism, and wherein shading blade is connected with screw nut drive mechanism. When the aperture size needs to be adjusted, the shading blade is controlled to do reciprocating linear motion through the lead screw nut transmission mechanism, and then the shading blade is driven to shade the periscopic camera, the incident illumination intensity and the depth of field of the periscopic camera are changed, the shooting effect is enhanced, and meanwhile, the application range is widened.

Based on the foregoing embodiments, the present application provides a periscopic camera, and the periscopic camera 103 includes the iris diaphragm module 100 of the foregoing embodiments. Alternatively, the shape of the light-shielding blades 101 in the iris diaphragm module 100 is a long strip to conform to the shape of the periscopic camera 103.

Alternatively, the aperture size of the light-shielding blade 101 is smaller than the body aperture size of the periscopic camera 103. Therefore, when the shutter blade 101 is driven by the motor 1021 indirectly to move linearly and reaches a predetermined position, the field of view of the original partial aperture of the periscopic camera 103 is blocked and the size of the aperture is reduced, thereby realizing the switching of the aperture mode of the periscopic camera 103. It should be noted that the size of the opening of the light-shielding blade 101 can be set according to actual requirements, so as to achieve different aperture switching effects.

In the practical use process, when the aperture size needs to be adjusted, the lead screw nut transmission mechanism 102 controls the shading blade 101 to do reciprocating linear motion, so that the shading blade 101 is driven to shade the periscopic camera 103, the incident illumination intensity and the depth of field of the periscopic camera are changed, the shooting effect is enhanced, and meanwhile, the application range is widened.
