Users can switch the aperture size according to different shooting scenes to obtain the best amount of light entering and ensure the imaging effect.

[0034] The present disclosure provides a lens assembly. Figure 1 is a schematic diagram of an exploded structure of a lens assembly in an exemplary embodiment of the present disclosure, Figure 2 is a schematic cross-sectional structure diagram of a lens assembly in an exemplary embodiment of the present disclosure, such as Figure 1 , Figure 2 As shown, Figure 2The middle dotted line may refer to the direction of the optical axis. The lens assembly 1 includes a bracket 12, a lens 11, and an elastic structural member 13. The bracket 12 includes a main frame 121 and a light-transmitting base 122. The main frame 121 includes a first opening 1211 and a second opening 1212. The light-transmitting base 122 is assembled in the first opening 1211. The lens 11 is assembled in the second opening 1212. The lens 11, the main frame 121, and the light-transmitting base 122 form an installation space. The elastic structural member 13 is assembled in the installation space. The elastic structural member 13 forms a light-transmitting space 14. The projection of the lens 11 in the direction of the optical axis covers the light-transmitting space 14, so that light propagates from the lens 11 through the light-transmitting space 14 and the light-transmitting base 122. When the elastic structural member 13 is deformed by force, the radial size of the light-transmitting space 14 changes within a preset range to change the amount of light entering the lens.

[0035] Since the lens assembly 1 includes an elastic structural member 13, the projection of the lens 11 in the optical axis direction covers the light-transmitting space 14 surrounded by the elastic structural member 13, and light is transmitted from the lens 11 through the light-transmitting space 14 and the light-transmitting base 122. When the elastic structural member 13 is deformed by force, the radial dimension of the light-transmitting space 14 changes within a preset range, thereby being able to change the amount of light entering the lens. The deformation of the elastic structural member 13 by force can achieve a continuous aperture adjustment effect, and the aperture adjustment range is large, which helps to improve the shooting effect and quality. In addition, the lens assembly 1 has fewer parts, high structural reliability and low cost.

[0036] The main frame 121 may be made of an opaque material, and the elastic structural member 13 may be a black or other color light-shielding elastic structure. The light-transmitting base 122 may be made of a light-transmitting material, for example, the light-transmitting base 122 is made of a transparent material.

[0037] It should be noted that the deformation of the elastic structural member 13 can be achieved by air pressure, mechanical push-pull, etc. The deformation position and degree of the elastic structural member 13 can be set according to specific needs so as to adjust the radial size of the light-transmitting space 14.

[0038] In some embodiments, one end of the elastic structural member 13 is sealed with the lens 11 and / or the main frame 121, and the other end of the elastic structural member 13 is sealed with the light-transmitting base 122 to separate the installation space into the light-transmitting space 14 and the adjustment space 15. The lens assembly 1 also includes an air pressure control device, which is connected to the light-transmitting space 14 and / or the adjustment space 15 to control the deformation of the elastic structural member 13 through air pressure. That is, the elastic structural member 13 is deformed by the force of the air pressure acting on the elastic structural member 13, and the deformation accuracy is high and easy to control.

[0039] For example, the air pressure control device can be connected to the regulating space 15, and the light-transmitting space 14 can be used as a closed space. In the unstressed state, the radial size of the light-transmitting space 14 surrounded by the elastic structure 13 can correspond to the minimum light entering the aperture. Figure 4 As shown in FIG. 1 , due to the pressure difference between the light-transmitting space 14 and the regulating space 15, the elastic structure 13 expands radially toward the periphery, thereby increasing the radial dimension of the light-transmitting space 14 and increasing the amount of light entering. When the pressure of the regulating space 15 is restored from the decrease to the same or close to that of the light-transmitting space 14, the elastic structure 13 recovers its deformation to the shape shown in FIG. Figure 3 In the state shown, the radial dimension of the light-transmitting space 14 is reduced, and the amount of light entering is reduced accordingly.

[0040] Or, in the unstressed state, such as Figure 3 As shown, the radial dimension of the light-transmitting space 14 surrounded by the elastic structural member 13 can correspond to the light entering the aperture. Figure 4 As shown in FIG. 1 , due to the pressure difference between the light-transmitting space 14 and the regulating space 15, the elastic structure 13 expands radially toward the periphery, thereby increasing the radial dimension of the light-transmitting space 14 and increasing the amount of light entering. When the pressure of the regulating space 15 is restored from the decrease to the same or close to that of the light-transmitting space 14, the elastic structure 13 recovers its deformation to the shape shown in FIG. Figure 3 In the state shown, the radial dimension of the light-transmitting space 14 is reduced, and the amount of light entering is reduced accordingly. When the air pressure in the regulating space 15 is further increased, the elastic structure 13 is compressed to compress the radial dimension of the light-transmitting space 14 to correspond to the minimum light entering dimension of the aperture.

[0041] The radial dimension of the light-transmitting space 14 surrounded by the elastic structural member 13 in the unstressed state can be set according to requirements, and the present disclosure does not limit this.

[0042] In other embodiments, the air pressure control device can be connected to the light-transmitting space 14 to adjust the air pressure of the light-transmitting space 14 to adjust the deformation of the elastic structure 13. In other embodiments, the air pressure control device can be connected to the light-transmitting space 14 and the adjustment space 15 at the same time to adjust the air pressure of the light-transmitting space 14 and the adjustment space 15 to adjust the deformation of the elastic structure 13.

[0043] In the above embodiment, the adjustment space 15 can be arranged at the periphery of the light-transmitting space 14 along the circumferential direction to form an air pressure force around the elastic structure 13, so that the light-transmitting space 14 obtains a relatively uniform radial dimension change in the circumferential direction.

[0044] For example, the adjustment space 15 can be an annular space, so as to utilize the uniform air pressure distribution in the annular space in the circumferential direction to improve the deformation uniformity of the elastic structural member 13, so that the light-transmitting space 14 obtains a uniform and consistent radial dimension change in the circumferential direction, thereby improving the accuracy of the light entering the light-transmitting space 14.

[0045] Furthermore, the thickness of the elastic structure 13 may be greater than the height of the installation space in the optical axis direction, so that one end of the elastic structure 13 abuts against the lens 11 and / or the main frame 121, and the other end of the elastic structure 13 abuts against the light-transmitting base 122. By utilizing the elastic properties of the elastic structure 13 itself, an interference fit of the elastic structure 13 on one side of the lens 11 and / or the main frame 121 and one side of the light-transmitting base 122 is achieved, thereby improving the sealing reliability and forming a pressure difference between the light-transmitting space 14 and the adjustment space 15.

[0046] Among them, one end of the elastic structure 13 can be in contact with the lens 11 to avoid sealing failure when it is simultaneously matched with the lens 11 and the main frame 121, thereby improving the sealing of the elastic structure 13 in the adjustment space 15 and the light-transmitting space 14 after assembly.

[0047] The above-mentioned elastic structural member 13 may also include a first abutting plane 131 and a second abutting plane 132 which are relatively arranged, wherein the first abutting plane 131 abuts against the lens 11 and / or the main frame 121, and the second abutting plane 132 abuts against the light-transmitting base 122, so as to achieve abutment with the lens 11 and / or the main frame 121 and the light-transmitting base 122 through a planar structure, thereby improving the reliability of abutment sealing.

[0048] In the above embodiment, the elastic structure 13 may include an inner side surface 133 surrounding the light-transmitting space 14 and an outer side surface 134 arranged opposite to the inner side surface 133, and the outer side surface 134 includes an arc surface. The arc surface of the outer side surface 134 can be easily deformed after being subjected to force, thereby improving the reliability of deformation control.

[0049] In some embodiments, a deformation cavity may be provided inside the elastic structure 13, and the lens assembly 1 further includes an air pressure control device, which is connected to the deformation cavity to control the deformation of the elastic structure 13 through air pressure. The elastic structure 13 is deformed by using the force of the air pressure acting on the cavity inside the elastic structure 13, with high deformation accuracy and easy control, while reducing the sealing requirements for the light-transmitting space 14 and the adjustment space 15.

[0050] The elastic structure 13 may include an inner side surface 133 surrounding the light-transmitting space 14, and the deformation cavity includes an annular cavity arranged near the inner side surface 133. The deformation cavity is close to the inner side surface 133, so that the inner side of the elastic structure 13 is more likely to form a deformation that changes the radial size of the light-transmitting space 14, thereby improving the deformation reliability.

[0051] Alternatively, the deformation cavity may also be a plurality of cavities inside the elastic structure 13, so as to achieve deformation adjustment by coordinating the pressure inside the plurality of cavities, thereby improving the flexibility of adjusting the radial size of the light-transmitting space 14. The plurality of cavities may be evenly distributed inside the elastic structure 13, or distributed near the inner side surface 133, or in other distribution modes, which are not limited in the present disclosure.

[0052] In the above embodiment, the radial dimension from the center of the deformation cavity to the inner side surface 133 can be smaller than the dimension from the center of the deformation cavity to the two end surfaces of the elastic structure 13 in the optical axis direction, so as to avoid excessive deformation of the elastic structure 13 in the optical axis direction and affect the structural stability of the lens.

[0053] In other embodiments, the lens assembly 1 may further include a mechanical driving member connected to the elastic structural member 13 to control the deformation of the elastic structural member 13 through a push-pull force. The mechanical driving member has better push-pull control stability on the elastic structural member 13, which can not only obtain continuous and stable dimensional changes by utilizing the elastic deformation of the elastic structural member 13, but also helps to reduce the influence of air pressure on the lens assembly 1 and improve the service life of the elastic structural member 13.

[0054] The elastic structure 13 may include an inner side surface 133 that encloses the light-transmitting space 14 and an outer side surface 134 that is arranged opposite to the inner side surface 133. The outer side surface 134 is evenly provided with connecting parts along the circumference, and the connecting parts are connected to the mechanical driving part. The uniform deformation formed in the process of the mechanical driving part pushing and pulling the elastic structure 13 can be improved by evenly providing the connecting parts along the circumference, thereby improving the stability of the aperture change.

[0055] In the above embodiment, the elastic structure 13 may include an annular structure, and the cross section of the light-transmitting space 14 in the direction perpendicular to the optical axis is circular. The above structural setting can make the light-incoming range of the lens assembly 1 always remain circular during use, thereby improving the stability and reliability of aperture control.

[0056] The present disclosure further provides an electronic device, which includes the lens assembly 1 described above.

[0057] Since the lens assembly 1 includes an elastic structural member 13, the projection of the lens 11 in the optical axis direction covers the light-transmitting space 14 surrounded by the elastic structural member 13, and light is transmitted from the lens 11 through the light-transmitting space 14 and the light-transmitting base 122. When the elastic structural member 13 is deformed by force, the radial size of the light-transmitting space 14 changes within a preset range, thereby changing the amount of light entering the lens. The above-mentioned deformation of the elastic structural member 13 by force can obtain a continuous aperture adjustment effect, and the aperture adjustment range is large, which helps to improve the shooting effect and quality.

[0058] It should be noted that the above-mentioned electronic device can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted terminal, a medical terminal, etc., and the present disclosure does not limit this.

[0059] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
