Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

A camera is generally provided in an electronic device to make the electronic device have a camera function. Because the camera is exposed to allow light to enter, a piece of Cover Glass (Cover Glass) is usually added above the camera to protect the camera. Because the glass has certain thickness to in order to prevent that camera and cover plate glass from colliding and consequently make the lens of camera damage, consequently also keep certain safe distance between camera and the glass cover plate. Since the thickness of the electronic device is fixed, the thickness and the safety distance of the cover glass occupy certain sizes, so that the total optical length (TTL) allocated to the camera is greatly limited, and the total optical length directly affects or limits the imaging quality.

In view of the above, in order to solve the above problems, the present application provides a camera assembly. Referring to fig. 1, fig. 1 is a schematic structural diagram of a camera head assembly according to an embodiment of the present disclosure. The present embodiment provides a camera assembly 1 including a decoration 10, a camera module 20, and a light-transmissive protection member 30. The decoration 10 has a receiving hole 11. At least a portion of the light-transmissive protector 30 is located in the receiving hole 11 and is mounted on the decoration 10, and the light-transmissive protector 30 has a through hole 31. Part of the camera module 20 is located in the through hole 31 and the camera module 20 is exposed.

The camera assembly 1 provided in the present embodiment can be applied to various fields and apparatuses that require zooming, and the present embodiment does not limit this.

The camera module 1 mainly includes a decoration 10, a camera module 20, and a light-transmitting protection member 30. The decoration 10 mainly plays a role of installation, protection, decoration, and the like, and can install structural members to the decoration 10 and protect various structural members located in the decoration 10. The decoration 10 has a receiving hole 11, in other words, the decoration 10 is shaped as a ring, the decoration 10 is surrounded to form the receiving hole 11, and the receiving hole 11 can be used for installing the subsequent camera module 20.

The camera module 20 is a structural member mainly used for shooting in the camera module 1. At least a portion of the camera module 20 is located in the receiving hole 11, in the present embodiment, only the object side end of the camera module 20 is located in the receiving hole 11, and the rest portion is located outside the decoration 10.

The light-transmissive protector 30 is mainly used to protect the camera module 1, the light-transmissive protector 30 includes, but is not limited to, glass, sapphire, etc., and the thickness of the light-transmissive protector 30 is not less than 0.5mm. At least a portion of the light-transmissive protection member 30 is located in the receiving hole 11, and the present embodiment is schematically illustrated only in the case that the light-transmissive protection member 30 is located in the receiving hole 11 and is mounted on the decoration 10. Alternatively, the object side surface of the light-transmissive protector 30 is flush with the object side surface of the garnish 10. Further alternatively, the object side surface of the light-transmissive protector 30, the object side surface of the garnish 10, and the object side surface of the camera module 20 are flush.

And the transparent protection member 30 is disposed corresponding to the outer periphery of the camera module 20, compared to the related art in which the transparent protection member 30 is disposed on the object side of the camera module 20, the position of the transparent protection member 30 is changed in this embodiment. In other words, the height of the light-transmissive protector 30 is reduced, so that the light-transmissive protector 30 is disposed inside the decoration 10 and on the peripheral side surface of the camera module 20. The above structure can also be understood that the light-transmissive protection member 30 has a through hole 31, the light-transmissive protection member 30 is located in the receiving hole 11 of the decoration 10, and the object-side end of the camera module 20 is located in the through hole 31 of the light-transmissive protection member 30, i.e. the light-transmissive protection member 30 is located between the decoration 10 and the camera module 20. So that the thickness of the light-transmissive protective member 30 itself can be ignored, the overall thickness of the camera head assembly 1 is reduced, for example by at least 0.5mm. And moreover, a safe distance does not need to be kept between the light-transmitting protection piece 30 and the object side surface of the camera module 20, and the total thickness of the camera assembly 1 can be further reduced.

In addition, the transparent protection member 30 is located between the decoration member 10 and the camera module 20, so that external foreign objects and impurities can be prevented from entering the camera assembly 1 through a gap between the decoration member 10 and the camera module 20, and the camera assembly 1 can be protected.

In summary, the camera assembly 1 provided in the present embodiment reduces the total thickness of the camera assembly 1, in other words, when the thickness of the camera assembly 1 is fixed, the total optical length of the camera module 20 can be increased, and the camera module 20 with a longer total optical length is disposed in a limited space, thereby improving the imaging quality of the camera assembly 1. In other words, the height of the camera module 20 is increased on the basis of not increasing the total thickness of the camera assembly 1, so that the camera module 20 can be used with a photoelectric sensor with a larger image plane, thereby realizing the dual guarantee of the performance and the resolution of the camera module 20.

Referring to fig. 1-2, fig. 2 is a schematic structural diagram of a cemented lens according to an embodiment of the present application. In this embodiment, the camera module 20 includes a lens barrel 22 and at least one lens 21, the lens barrel 22 has an accommodating space 221, and the at least one lens 21 is disposed in the accommodating space 221; the lens 21 of the at least one lens 21 close to the object side of the camera assembly 1 is a cemented lens 210, the cemented lens 210 is fixed in the lens barrel 22, and the cemented lens 210 includes a light-transmitting protection layer 211 close to the object side of the camera assembly 1.

The camera module 20 is composed of a plurality of structural members, and the present embodiment only introduces the lens barrel 22 and the lens 21, wherein the lens barrel 22 mainly plays a role of protecting and installing various lenses 21, the lens barrel 22 has an accommodating space 221, and other structural members of the camera module 20 can be disposed in the accommodating space 221. The camera module 20 includes at least one lens 21, the at least one lens 21 is arranged along the optical axis in a predetermined manner, thereby obtaining the camera module 20 required by the user.

The lens 21 on the side close to the camera module 1 among the at least one lens 21 is named as a cemented lens 210 in the present embodiment and the following description. Here, the cemented lens 210 refers to a composite lens 21 prepared by two or more lens 21 layers through a cementing process. The cemented lens 210 of the present embodiment includes a light-transmitting protective layer 211 on the side close to the camera head assembly 1. The transparent protective layer 211 has a light-transmitting property, which allows light to pass through so that the camera module 20 can work normally. And the light-transmitting protective layer 211 also has a protective effect for protecting the other lens 21 layers of the cemented lens 210 and the other lenses 21 in the camera module 20, and preventing the lens 21 from being cracked when the camera module 1 falls down or the like.

Alternatively, the light-transmitting protective layer 211 includes, but is not limited to, a protective glass made of high-strength glass. Optionally, the thickness of the light-transmissive protective layer 211 is 0.1-0.5mm. If the thickness of the light-transmitting protective layer 211 is less than 0.1mm, the thickness of the light-transmitting protective layer 211 is too thin to effectively protect other lens 21 layers and other lenses 21 in the cemented lens 210. If the thickness of the light-transmitting protective layer 211 is greater than 0.5mm, the thickness of the light-transmitting protective layer 211 is too thick, which may affect the thickness of other lens 21 layers in the cemented lens 210 based on the protection function. Therefore, only the thickness of the light-transmitting protective layer 211 is 0.1-0.5mm, so that the light-transmitting protective layer 211 has a protective function and does not affect the thickness of the other lens 21 layers in the cemented lens 210.

Please refer to fig. 2-3 together, wherein fig. 3 is a schematic structural diagram of a cemented lens according to another embodiment of the present disclosure. In this embodiment, the object-side surface of the light-transmitting protective layer 211 is a plane or a spherical surface. In this embodiment, the object side surface of the light-transmitting protective layer 211 can be designed to be a plane or ground to be a spherical surface. Fig. 2 is a schematic diagram of the object side of the light-transmitting protective layer 211 being a plane. Fig. 3 is a schematic diagram of the object-side surface of the light-transmitting protective layer 211 being a spherical surface. When the object side of the light-transmitting protective layer 211 is a plane, the thickness of the light-transmitting protective layer 211 can be further reduced, and more space is made for other lens 21 layers. When the object side surface of the light-transmitting protective layer 211 is a spherical surface, the light-transmitting protective layer also has a convergence effect on light, participates in imaging, improves the brightness, and further improves the imaging quality.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a cemented lens according to another embodiment of the present application. In this embodiment, the cemented lens 210 further includes a light-transmitting layer 212, and the light-transmitting layer 212 is farther from the object side of the camera head assembly 1 than the light-transmitting protection layer 211.

The cemented lens 210 may further include a light-transmitting layer 212 in addition to the light-transmitting protection layer 211, wherein the light-transmitting layer 212 is farther from the object side of the camera head assembly 1 than the light-transmitting protection layer 211. In other words, the light-transmitting protection layer 211 is further outside, and the light-transmitting layer 212 is further inside. From the above, it can be seen that the light-transmitting protective layer 211 mainly plays a role of protection, and the light-transmitting layer 212 mainly plays a role of optical imaging, that is, the present embodiment utilizes a two-layer lens 21 layer structure to make the light-transmitting protective layer 211 near the outer side play a role of protection, so as to prevent other lens 21 layers or other lenses 21 from being cracked; the transparent layer 212 is used for optical imaging.

Alternatively, the transparent layer 212 may include, but is not limited to, a molded glass, and may be formed by a molding process to improve the imaging quality of the camera assembly 1.

Optionally, the thickness of the light-transmitting layer 212 is 0.15-0.5mm. If the thickness of the light-transmitting layer 212 is less than 0.15mm, the light-transmitting layer 212 is too thin, the preparation process is complex, and the forming is difficult. If the thickness of the transparent layer 212 is greater than 0.5mm, the thickness of the other lens 21 is affected by the excessive thickness of the transparent layer 212. Therefore, the thickness of the transparent layer 212 is 0.15-0.5mm, which can reduce the difficulty of manufacturing and does not affect the thickness of other lenses 21.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a cemented lens according to another embodiment of the present application. In this embodiment, the image-side surface of the light-transmitting layer 212 is aspheric. In this embodiment, the image-side surface of the light-transmitting layer 212 can be designed to be aspheric, thereby further improving the imaging quality. The specific parameters of the image-side surface of the transparent layer 212 are not limited in this embodiment, and may be designed according to actual situations.

Please refer to fig. 4-6, fig. 6 is a schematic structural diagram of a cemented lens according to another embodiment of the present application. In this embodiment, the shape of the image-side surface of the light-transmitting protective layer 211 is the same as the shape of the object-side surface of the light-transmitting layer 212.

The shapes of the object-side surface of the light-transmitting protective layer 211 and the image-side surface of the light-transmitting layer 212 are described above, and the embodiment is not limited thereto as long as the shape of the image-side surface of the light-transmitting protective layer 211 is the same as that of the object-side surface of the light-transmitting layer 212, so that the light-transmitting protective layer 211 can be closely disposed on one side of the light-transmitting layer 212. This further reduces the thickness of the cemented lens 210 and improves the light imaging quality.

Alternatively, as shown in fig. 4 to 5, when the image-side surface of the light-transmitting protective layer 211 is a plane, the object-side surface of the light-transmitting layer 212 is also a plane. As shown in fig. 6, when the image-side surface of the light-transmitting protective layer 211 is a spherical surface, the object-side surface of the light-transmitting layer 212 is also a spherical surface. When the image-side surface of the light-transmitting protective layer 211 is aspheric, the object-side surface of the light-transmitting layer 212 is also aspheric. Further alternatively, when the image-side surface of the light-transmitting protective layer 211 is spherical and concave, the object-side surface of the transparent layer 212 is also spherical and convex. Alternatively, when the image-side surface of the light-transmitting protective layer 211 is spherical and convex, the object-side surface of the light-transmitting layer 212 is also spherical and concave, so that the light-transmitting protective layer 211 and the light-transmitting layer 212 are closely attached together. Further alternatively, when the image-side surface of the light-transmitting protective layer 211 is aspheric and concave, the object-side surface of the light-transmitting layer 212 is also aspheric and convex. Alternatively, when the image-side surface of the light-transmitting protective layer 211 is aspheric and convex, the object-side surface of the light-transmitting layer 212 is also aspheric and concave, so that the light-transmitting protective layer 211 and the light-transmitting layer 212 are closely attached together.

In this embodiment, the cemented lens 210 further includes a light-transmitting bonding layer 213, and the light-transmitting bonding layer 213 is bonded between the light-transmitting protection layer 211 and the light-transmitting layer 212.

This embodiment can also be achieved by adding a light-transmissive adhesive layer 213, wherein the light-transmissive adhesive layer 213 has viscosity and does not affect the transmission of light. Optionally, the light transmissive adhesive layer 213 includes, but is not limited to, OCA optical glue. In the present embodiment, the light-transmissive protective layer 211 and the light-transmissive layer 212 are bonded by the light-transmissive bonding layer 213, so as to improve the connection performance of the cemented lens 210.
