Description

Technical Field

[0001] The utility model relates to the field of lens films, in particular to an injection-molded silicone lens film. Background Art

[0002] The main function of the lens is to collect the light reflected from the object being illuminated and focus it on the CCD. The image projected onto the CCD is inverted, and the camera circuit has the function of reversing it. Its imaging principle is the same as that of the human eye. With the development of smartphones, the camera lenses configured on mobile phones are also constantly iterating towards higher precision. However, mobile phone cameras are relatively fragile, so configuring a lens protective film on mobile phone cameras to enhance lens protection has become an important design.

[0003] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

[0004] In the prior art, most mobile phone lens protective films are fixed directly to the outer wall of the protrusion of the mobile phone camera by adhesive. This fixing method may cause the adhesive to overflow onto the camera surface during use, which will reduce the imaging quality of the camera and affect the appearance of the camera after the protective film is removed. At the same time, the fixing process is relatively cumbersome.

[0005] Therefore, those skilled in the art provide an injection-molded silicone lens film to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the existing technology and to propose an injection-molded silicone lens film. When the film is installed on the lens, the elastic silicone material of the limiting pad squeezes and fixes the camera through the elasticity of the silicone when it is deformed, thereby achieving quick installation of the lens and preventing the problem of adhesive coating on the lens surface affecting the imaging quality and residual adhesive affecting the aesthetics caused by the traditional fixing method.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] An injection-molded silicone lens film comprises a casing, the casing comprising an outer shell, a veneer shell fixedly provided at the lower end of the inner wall of the outer shell, and a light-transmitting lens fixedly provided at the lower end surface of the veneer shell;

[0009] A card pad is provided inside the housing, and the card pad includes a limiting pad. A protective pad is fixedly provided on the lower end of the inner wall of the limiting pad.

[0010] Furthermore, a slot is provided on the lower end surface of the veneer shell, and the light-transmitting lens is fixedly arranged inside the slot.

[0011] Furthermore, the limiting pad is fixedly arranged at the upper end of the inner wall of the shell, and the protection pad is fixedly arranged on the upper end surface of the veneer shell.

[0012] Furthermore, a light-transmitting groove is provided through the center of the upper end surface of the veneer shell and the protection pad.

[0013] Furthermore, an inclined concave surface is provided on the upper end of the inner wall of the limiting pad, and the inner diameter of the upper end surface of the limiting pad is greater than the inner diameter of the lower end surface.

[0014] Furthermore, the limiting pad and the protection pad are both made of elastic silicone material.

[0015] Furthermore, the light-transmitting lens is made of transparent PC material.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model proposes an injection-molded silicone lens film. When the device is attached to the lens, the inner wall of the limit pad made of elastic silicone material is concave inward under the pressure of the lens, so that the lens can be squeezed by the elastic force generated after the concavity, so that the limit pad wraps the outer wall of the lens and fits tightly against the outer wall of the lens. The friction force generated between the limit pad made of silicone material and the outer wall of the lens has the effect of fixing the position of the device, and the protective pad can prevent the lens from directly contacting the veneer shell and being scratched. While facilitating the installation of the lens film, it can also prevent the traditional adhesive fixing method from leaving residual adhesive on the lens surface or the outer wall of the lens, thereby affecting the camera imaging quality and the appearance of the outer wall of the camera.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 4 , an embodiment provided by the utility model:

[0026] An injection-molded silicone lens film comprises a housing 1, the housing 1 comprising an outer shell 101, a veneer shell 102 fixedly provided at the lower end of the inner wall of the outer shell 101, and a light-transmitting lens 2 fixedly provided at the lower end surface of the veneer shell 102;

[0027] A card pad 3 is provided inside the housing 1 . The card pad 3 includes a limiting pad 301 . A protective pad 302 is fixedly provided on the lower end of the inner wall of the limiting pad 301 .

[0028] Specifically, the outer shell 101 and the veneer shell 102 can respectively wrap and protect the outer wall and the lens surface of the lens, so that the lens can be used for normal shooting through the transparent lens 2 while preventing the lens from being damaged by collision during use. The limiting pad 301 can achieve rapid installation of the device, and the protective pad 302 can prevent the problem of scratching the lens due to direct contact between the veneer shell 102 and the lens.

[0029] Reference Figure 3 A card slot 5 is provided on the lower end surface of the veneer shell 102 , and the light-transmitting lens 2 is fixedly arranged inside the card slot 5 .

[0030] Specifically, the position of the light-transmitting lens 2 can be fixed by the card slot 5 , and the light-transmitting lens 2 can be flush with the lower end surface of the veneer shell 102 , so as to reduce the probability of the light-transmitting lens 2 being damaged or broken.

[0031] Reference Figure 1 、 Figure 4 The limiting pad 301 is fixedly arranged at the upper end of the inner wall of the shell 101, and the protection pad 302 is fixedly arranged on the upper end surface of the veneer shell 102.

[0032] Specifically, the design of the limiting pad 301 being fixedly arranged inside the housing 101 can achieve a fixing effect on the position of the device during installation, and the protective pad 302 can prevent the lens from directly contacting the veneer shell 102.

[0033] Reference Figure 3 A light-transmitting groove 4 is formed through the center of the upper end surface of the veneer shell 102 and the protection pad 302.

[0034] Specifically, the lens can pass through the light-transmitting slot 4 to prevent the device from blocking the camera field of view.

[0035] Reference Figure 1 、 Figure 4 The upper end of the inner wall of the limiting pad 301 is provided with an inclined concave surface, and the inner diameter of the upper end surface of the limiting pad 301 is larger than the inner diameter of the lower end surface.

[0036] Specifically, the design of the inclined concave surface can reduce the resistance of the lens when entering the interior of the limiting pad 301 when the device is installed on the lens, so that the lens can enter the interior of the limiting pad 301 more smoothly.

[0037] Reference Figures 1 to 4 The limiting pad 301 and the protection pad 302 are both made of elastic silicone material.

[0038] Specifically, the silicone limit pad 301 can squeeze the outer wall of the lens through deformation during the installation process to achieve the effect of fixing the position of the device. The silicone material of the protective pad 302 can fit the lens surface to prevent the lens surface from directly contacting the veneer shell 102 and causing scratches.

[0039] Reference Figures 1 to 4 , the light-transmitting lens 2 is set to be a transparent PC material.

[0040] Specifically, the lens can be protected and dust can be prevented from falling on the lens surface without affecting the normal imaging of the lens.

[0041] Working principle: When in use, the device is directly put on the outer wall of the lens. During the insertion process, the lens is smoothly embedded in the limiting pad 301 through the inclined concave surface set at the upper end of the inner wall of the limiting pad 301. During the embedding process of the lens, the limiting pad 301 made of elastic silicone material is deformed as the lens is embedded, so that the inner wall of the limiting pad 301 is squeezed against the outer wall of the lens through the elasticity of the silicone, thereby achieving a wrapping effect on the outer wall of the lens. In this way, the position of the device is fixed by the friction between the limiting pad 301 made of silicone material and the outer wall of the lens, preventing the problem of residual glue left on the lens surface and outer wall due to the traditional adhesive fixing method, affecting the imaging effect and the appearance of the lens.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
