Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Fig. 2-6 show schematic structural views of preferred embodiments of the camera head assembly of the present application. The camera assembly comprises a lens module 1, a cover plate 2 positioned on the light inlet side of the lens module 1 and an image sensing component 3 positioned on the light outlet side of the lens module 1. In order to overcome the problems that the time and labor are wasted when the ND mirror is manually replaced in the prior art, the size of a camera assembly is large, and the camera assembly is not suitable for electronic products such as mobile phones, the camera assembly comprises an electrochromic component 4 positioned between a cover plate 2 and an image sensing component 3.

It should be noted that since the electrochromic device has a characteristic that the light transmittance of the electrochromic material is changed by using an electrochemical redox reaction, it is well known and the operation principle thereof is not described in detail herein. In the present application, the electrochromic device 4 includes a first substrate 41, an electrochromic layer 42, and a second substrate 43, which are sequentially disposed from top to bottom, as shown in fig. 1.

Of course, other configurations are possible, for example, the electrochromic device 4 includes only the first substrate 41, and the electrochromic layer 42 is coated or plated on the first substrate 41, and it is easily understood that the electrochromic device having only one substrate has a thinner thickness and saves more material than the electrochromic device having two substrates, and when combined with a camera module, the volume and size of the camera module can be more reliably miniaturized, as will be described in detail below.

For the purposes of this application, the electrochromic element 4 may be located between the cover plate 2 and the lens module 1. In this structure, the first substrate 41 may be connected to the surface of the cover plate 2 close to the lens module 1, as shown in fig. 2, or the first substrate 41 may be directly formed by the cover plate 2, that is, the first substrate 41 is the cover plate 2, so as to fix the electrochromic component 4 to the cover plate 2, as shown in fig. 3, it is obvious that this case corresponds to a structure in which the electrochromic component only includes the first substrate 41, and the electrochromic layer 42 is coated or plated on the first substrate 41.

Adopt this kind of position structure, camera subassembly production simple process, but volume production nature is strong, moreover to first situation, this kind of structure can become and change the thickness of apron to improve the intensity of camera apron, and the second situation is owing to having left out first base plate, and the size and the thickness of camera subassembly are thinner lighter and handy in comparison in the past, can be better be applicable to equipment such as cell-phone, and application scope is wide.

The electrochromic element 4 may be located in the lens module 1, as shown in fig. 4, the lens module 1 is composed of a plurality of stacked lenses, which is well known, and is not excessively expanded here. In this case, the electrochromic element 4 may be fixed to the lens module 1 by fixing the first substrate 41 to the lens close to the first substrate 41 and fixing the second substrate 43 to the lens close to the second substrate 43.

For an electrochromic component having only one substrate, the electrochromic layer, the substrate, and the lens close to each other may be fixed separately, so that the electrochromic component is fixed in the lens module.

Because the electrochromic component has the same optical action and effect as the lens, the electrochromic component can also be used for replacing one or more lenses in the conventional lens module 1, so that the function and effect of the electrochromic component can be exerted, and the roles of the lenses can be taken into consideration, therefore, compared with the conventional lens module, the structure omits one lens, and the electrochromic component 4 is used for replacing the lens, so that one lens in the lens module 1 is the electrochromic component 4.

The fixing of the electrochromic element with only one substrate is referred to the above-mentioned case and will not be described herein.

Meanwhile, it should be noted that, in order to ensure that the function of the lens module is not affected and to better realize that the electrochromic element performs the optical function of the lens, the first substrate 41 and the second substrate 43 need to be processed into curved surfaces at corresponding positions along with the change of the lens curve, so as to meet the design requirements of the lens.

Of course, no matter the electrochromic component is located in the lens module as a new member or replaces one or more lenses in the lens module, the electrochromic component at this time is more likely to be located at the diaphragm in the lens module 1, because the light at the diaphragm is more concentrated, the electrochromic function of the electrochromic component can be more favorably exerted.

The camera module includes the above-mentioned components, and further includes the infrared filter 5 disposed between the lens module 1 and the image sensing component 3, so, as an advantage, the electrochromic component 4 may be disposed between the lens module 1 and the infrared filter 5, as shown in fig. 5, or between the infrared filter 5 and the image sensing component 3, or at least the surface of the second substrate 43 close to the image sensing component 3 is coated with the infrared cut-off film layer 44 to prevent the infrared rays from passing through, so that the electrochromic component 4 is directly disposed between the lens module 1 and the image sensing component 3 instead of the infrared filter 5 to take the functions of the infrared filter 5 into consideration, as shown in fig. 6, the first substrate 41 may be coated with or not coated with the infrared cut-off film layer 44.

When the electrochromic device has only one substrate, it is conceivable that the infrared cut film layer is coated on the side of the substrate remote from the electrochromic layer in order to be able to replace the infrared filter, and will not be described more extensively herein.

The electrochromic component 4 replaces the infrared filter 5, so that the cost of the camera assembly is greatly reduced, the thickness of the camera assembly is reduced, and the application range of the camera assembly is wider.

In the above structural design, the electrochromic component 4 can be fixed with the cover plate, the lens of the lens module, the lens module and the infrared filter, and the lens module and the image sensing component by gluing, screwing, ultrasonic welding, clamping, screwing, hinging and other methods, and the fixing method is common in the conventional combination of the lens and the lens, and therefore the details are not described here.

So, this application applies to the camera subassembly with electrochromic part through the xian has, utilize electrochromic part can make electrochromic material's luminousness change characteristics because of electrochemical redox reaction, effectively realize according to environment light intensity dynamic adjustment light transmissivity, solve in the past need manually to change the problem that the light adjustment can be realized to different ND filter side, be convenient for simultaneously according to actual need and set up electrochromic part in the relevant position department of camera subassembly, the design is more nimble, partly fuse in the camera subassembly with electrochromic part as the camera subassembly, when guaranteeing the transmissivity, can effectively ensure the miniaturization of the volume and the size of camera, make its electronic equipment such as cell-phone that is applicable to equally, application scope is wide.

While embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
