[0020] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] With the development of society, photographing equipment is widely used in people's lives, and users' functional requirements for photographing equipment are gradually increasing. At present, the outer layer of the lens body is provided with a protective lens to protect and waterproof the lens body. The protective lens is usually a flat lens. Therefore, in order to ensure that the solid part outside the protective lens does not block the lens field of view, it is usually necessary to make the size of the protective lens much larger than the size of the lens body.

[0027] However, due to the large size of the protective lens, the protective lens is easily bumped and worn during daily use of the shooting equipment, causing the protective lens to be scratched, which in turn causes blurred lens imaging and reduces the user experience.

[0028] In order to solve the above technical problems, the present disclosure provides a lens module and a shooting device. By setting the protective lens as a curved lens, the distance between the edge of the protective lens and the lens body is closer than that of a flat lens, which is beneficial to reducing the size of the protective lens and avoiding the risk of bumps and wear due to the large size of the protective lens. At the same time, the protective lens can also refract incident light onto the lens body and participate in the optical imaging process. Therefore, by reasonably setting the protective lens, the distance between the protective lens and the lens body can be further reduced, which can simultaneously meet the protection, waterproof functions and optical effects, is beneficial to the miniaturization of the lens module, and improves the user experience.

[0029] According to an exemplary embodiment, Figure 1-Figure 3 As shown, an embodiment of the present disclosure provides a lens module, which can be applied to electronic devices with shooting functions such as cameras, mobile terminals, and drones. In particular, the lens module can be applied to sports cameras to better achieve the design requirements of preventing lens bumps and miniaturizing the lens.

[0030] The lens module includes a lens body 10 and a protective lens 22. The protective lens 22 is detachably mounted on the outer layer of the lens body 10 (with the light incident direction as the inside). The protective lens 22 is used to provide protection for the lens body 10 to prevent the lens body 10 from being bumped and worn during use by the user. The protective lens 22 includes at least one curved lens that is configured to bulge in a direction away from the lens body 10, that is, the protective lens 22 can be configured as a curved lens, or a combination of multiple curved lenses. Since the protective lens 22 is a curved lens that bulges in a direction away from the lens body 10, compared to the solution in which the protective lens 22 is configured as a flat lens, the distance between the edge of the curved lens and the lens body 10 in a direction perpendicular to the optical axis is closer, that is, the size of the protective lens 22 can be smaller than that of the flat lens. For example, when a plane lens is used as the protective lens 22, in order to ensure that the solid part other than the protective lens 22 does not block the field of view of the lens body 10, the diameter of the plane lens needs to be increased as much as possible. The diameter of the plane lens is set to about 27.38 mm, and the protective lens 22 is set to a curved lens. Since the curved lens semi-encloses the lens body 10, while also ensuring that the solid part does not block the field of view of the lens body 10, the distance between the edge of the curved lens and the lens body 10 along the direction perpendicular to the optical axis is closer, that is, the diameter of the curved lens is smaller, only about 17.73 mm, which greatly reduces the size of the protective lens 22, thereby reducing the risk of scratching and wearing the protective lens 22.

[0031] Among them, the incident light is refracted by the protective lens 22 and then incident on the lens body 10, that is, the protective lens 22 participates in the optical imaging process during shooting, so that the distance between the protective lens 22 and the lens body 10 can be reduced by adjusting parameters such as the curvature of the protective lens 22, so as to improve the compactness of the lens design.

[0032] In the disclosed embodiment, the protective lens is set as a curved lens so that the distance between the edge of the protective lens and the lens body is closer than that of a flat lens, which is beneficial to reducing the size of the protective lens and avoiding the risk of bumps and wear due to the large size of the protective lens. At the same time, the protective lens can also refract incident light onto the lens body and participate in the optical imaging process. Therefore, by reasonably setting the protective lens, the distance between the protective lens and the lens body can be further reduced, which can simultaneously meet the protection, waterproof functions and optical effects, is beneficial to the miniaturization of the lens module, and improves the user experience.

[0033] In some embodiments, the protective lens 22 is detachably connected to the lens body 10. By setting the protective lens 22 to be detachably connected to the lens body 10, the protective lens 22 can be replaced separately when the protective lens 22 is damaged, thereby reducing the maintenance cost and extending the service life of the lens module. At the same time, the detachable connection between the protective lens 22 and the lens body 10 can also facilitate the realization of an optical ND filter (Neutral Density Filter) effect by replacing the protective lens 22 with different light transmittances.

[0034] Among them, the protective lens 22 can be configured to be detachably connected to the bracket 21 installed on the lens body 10, or it can be configured to be fixedly connected to the bracket 21 and the bracket 21 is detachably connected to the lens body 10. The embodiments of the present disclosure do not impose too many restrictions on this, as long as the protective lens 22 can be detachably connected to the lens body 10 and the protective lens 22 can be easily replaced.

[0035] In some embodiments, the protective lens 22 is fixedly connected to the bracket 21, and the bracket 21 is detachably connected to the lens body 10. The connection method between the bracket 21 and the lens body 10 includes at least one of a threaded connection, a magnetic connection, and a snap connection. In one example, the bracket 21 is threadedly connected to the lens body 10. In another example, the bracket 21 is snapped and magnetically connected to the lens body 10. In yet another example, the bracket 21 and the lens body 10 are simultaneously connected by a threaded connection, a magnetic connection, and a snap connection. It is understandable that the connection method between the bracket 21 and the lens body 10 can be only one of a threaded connection, a magnetic connection, and a snap connection, which is convenient for disassembly and replacement, or it can be connected by multiple methods at the same time to ensure easy disassembly while improving the stability and reliability of the connection.

[0036] In some embodiments, the lens body 10 includes a wide-angle lens 11. The focal length of the wide-angle lens 11 is shorter than that of a standard lens, but its viewing angle is greater than that of a standard lens and smaller than that of a fisheye lens, and its focal length is longer than that of a fisheye lens, so it is usually a convex lens. Since the lens is protruding, it is more prone to bumps and wear. Therefore, by providing a protective lens 22 to protect the wide-angle lens 11, it can not only prevent the lens body 10 from being bumped and worn, but also prevent the lens module from being flooded, which can greatly increase the service life of the lens module and improve the user experience.

[0037] In some embodiments, Figure 1-Figure 3As shown, the lens body 10 also includes a shell 12. The shell 12 is sleeved on the outside of the wide-angle lens 11 to provide protection for the wide-angle lens 11, and the bracket 21 is detachably connected to the shell 12. In one example, the lens body 10 is configured as a cylinder, the shell 12 is configured as a cylinder, and the bracket 21 is configured as a ring. Of course, it can be understood that the shape examples in the embodiments of the present disclosure are only used as general shapes, and the lens body 10, the shell 12 and the bracket 21 can also be provided with protrusions, avoidances, threads, grooves and other structures according to actual functional requirements, and the embodiments of the present disclosure do not impose too many restrictions on this.

[0038] In some embodiments, the curvature radius of the protective lens 22 ranges from 50 mm to 80 mm. The larger the curvature radius of the protective lens 22, that is, the flatter and closer to a plane the curved surface of the protective lens 22 is, the lower the sensitivity of the lens body 10 is. In order to reduce the size of the protective lens 22, the protective lens 22 needs to have a certain curvature. Therefore, setting the curvature radius of the protective lens 22 to range from 50 mm to 80 mm can reduce the size of the protective lens 22 while achieving the sensitivity requirements of the lens. Preferably, the curvature radius of the protective lens 22 can be set to 55 mm.

[0039] According to an exemplary embodiment, referring to Figure 1-Figure 3 As shown, the embodiment of the present disclosure provides a lens module, which includes a lens body 10 and a protective lens 22. The protective lens 22 is installed on the outer layer of the lens body 10. The protective lens 22 is used to provide protection for the lens body 10. The protective lens 22 is configured as a curved lens convex in a direction away from the lens body 10. Since the protective lens 22 is a curved lens convex in a direction away from the lens body 10, the size of the protective lens 22 can be smaller than that of a flat lens, thereby reducing the risk of scratching and wearing the protective lens 22. Among them, the incident light is refracted by the protective lens 22 and then incident on the lens body 10. In addition, the protective lens 22 can be detachably connected to the bracket 21 installed on the lens body 10, or it can be configured such that the protective lens 22 is fixedly connected to the bracket 21, and the bracket 21 is detachably connected to the lens body 10.

[0040] In one example, the lens module includes a bracket 21 and a plurality of protective lenses 22 with different transmittances, and the protective lenses 22 are detachably connected to the bracket 21. The bracket 21 is mounted on the lens body 10, and the protective lenses 22 are detachably connected to the bracket 21. The bracket 21 and the lens body 10 can be detachably connected or fixedly connected, and the protective lenses are detachably connected to the bracket 21 by snap-on or threaded connection. By setting a plurality of protective lenses 22 with different transmittances, and removing or installing one or several of the protective lenses 22, the protective lenses 22 as a whole can have different light transmittances for the lens body 10, that is, different light shielding capabilities, so as to achieve some special optical ND filter photography effects according to actual needs, such as using a larger aperture in a strong light environment.

[0041] In another example, the lens module includes a plurality of brackets 21, and the transmittance of the protective lens 22 installed on different brackets 21 is different. The bracket 21 is detachably connected to the lens body 10, and the protective lens 22 is fixedly connected to the bracket 21. By replacing different brackets 21, the protective lens 22 can have different light transmittances for the lens body 10, thereby achieving different optical ND filter photography effects. The protective lens 22 can be bonded to the bracket 21. The bracket 21 is arranged around the lens body 10, and a step surface 211 is arranged on the side of the bracket 21 away from the lens body 10. The step surface 211 is used to install the protective lens 22 and play a certain protective role on the protective lens 22. The protective lens 22 is bonded to the step surface 211.

[0042] In the disclosed embodiment, by providing a plurality of protective lenses with different transmittances, it is convenient to adjust the exposure, aperture and other parameters conveniently by replacing protective lenses with different light transmittances in different shooting environments or shooting requirements, thereby achieving an optical ND filter effect and improving the user experience.

[0043] According to an exemplary embodiment, Figure 1-Figure 3 As shown, the embodiment of the present disclosure provides a shooting device, which can be, for example, an electronic device with a shooting function such as a camera, a drone, a mobile terminal, etc., and the shooting device includes a lens module as described in the above embodiment. The lens module includes a lens body 10 and a protective lens 22, the protective lens 22 is mounted on the lens body 10, and the protective lens 22 includes at least one curved lens that is configured to convex in a direction away from the lens body 10, wherein the incident light is refracted by the protective lens 22 and then incident on the lens body 10, that is, the protective lens 22 participates in the optical imaging process during shooting, which is conducive to improving the compactness of the lens design. At the same time, since the protective lens 22 is a curved lens, the size of the protective lens 22 can be smaller than that of a flat lens, thereby reducing the risk of scratches and wear.
