[0002] The main camera of today's smartphones is usually designed to be slightly higher than the plane on the back of the phone; therefore, protective covers specifically designed to protect camera lenses have emerged. At present, there are roughly two types of protective covers on the market, each with its own disadvantages. In one type, the entire protective cover is made of glass. While protecting the camera lens, it also covers the functional area where the camera is located, such as the flash, noise reduction hole, rangefinder, etc., so that the height of the protective cover must be consistent with the protruding height of the camera. Not only is the thickness large and the weight heavy, but it also affects the normal use of other devices in the functional area. Another protective cover is made of a metal film and a lens protective ring that are buckled together. The problem is that when the lens protective ring is squeezed in reverse, the lens protective ring is easy to fall off and deform, and has low durability. In addition, the above two solutions are not convenient for adding textures, patterns, etc., and for diversified designs. Utility Model Content

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] A camera lens protective cover, such as Figures 1 to 6 As shown, it includes a base plate 1, a lens protection ring 2, a glass sheet 3 and an adhesive layer 4.

[0030] Among them, the bottom plate is formed by laminating at least two layers of composite material sheets 11, for example, it can be two or more layers, and at least one of the layers can be a transparent layer, a printed layer, a textured layer or an electroplated layer, that is, it is convenient to present different visual effects on the bottom plate by printing, electroplating patterns, setting as a transparent layer, etc., to increase the selling point of the product. At least one camera through hole 12 is hollowed out on the bottom plate, and the camera through hole corresponds to the position of the camera on the mobile phone or electronic device. At the same time, a plurality of functional area through holes 13 are hollowed out on the bottom plate, which correspond to the holes of the flash, noise reduction hole, and rangefinder, respectively. Preferably, since the bottom plate is formed by laminating multiple layers of composite material sheets, it is easier to process and shape than metal or glass materials, and the edge of the bottom plate has a chamfer 15, which is convenient for the protective cover to fit with the mobile phone or mobile phone case.

[0031] The lens protection ring is made of resin or PC material; the number of lens protection rings is consistent with the number of camera through holes, and the lens protection ring has a side wall 21 with a circular cross-section, that is, the lens protection ring is cylindrical as a whole, with a cavity inside, which is convenient for accommodating the part of the camera protruding from the back of the mobile phone. The inner surface of the side wall has a circular first load-bearing edge 22 extending toward the center of the lens protection ring, and the first load-bearing edge is used to support the glass sheet. After the lens protection ring is embedded in the camera through hole, part or all of the outer surface of the side wall is injection-molded with the inner wall of the camera through hole, that is, the outer surface of the side wall of the lens protection ring and the inner wall of the camera through hole are used as sealing surfaces, so that the two are very stable after being combined and are not easy to loosen or deform.

[0032] The number of glass sheets is consistent with the number of camera through holes. The glass sheets are used to cover the camera lens from the front to protect the lens. Specifically, the glass sheet is embedded on the first bearing edge of the lens protection ring, and the two can be adhered together by adhesive. Preferably, a circular printing strip 31 is provided around the periphery of the glass sheet, and the printing strip is used to cover the first bearing edge to make the product more beautiful.

[0033] The adhesive layer is in contact with the bottom surface of the bottom plate, and the adhesive layer is used to adhere the bottom plate to the back of the mobile phone or electronic device.

[0034] Furthermore, in one implementation, the outer surface of the side wall of the lens protection ring has a circular groove 23, and the inner wall of the camera through hole has a circular convex rib 14 corresponding to the groove. The lens protection ring is embedded in the camera through hole and after the groove and the convex rib are matched and engaged, part or all of the outer surface of the side wall is injection-molded and integrated with the inner wall of the camera through hole. That is, the groove and the convex rib play a role in positioning the lens protection ring and the camera through hole, and facilitating the injection of glue. Alternatively, the positions of the groove and the convex rib are swapped, the convex rib is set on the outer surface of the side wall of the lens protection ring, and the groove is set on the inner wall of the camera through hole, and the effect is consistent with the above.

[0035] Furthermore, in one implementation, on the inner wall of the camera through hole, there is at least one inlay layer 16 in the composite sheet with a circular groove or circular convex rib on the inner wall, and a supporting layer 17 located below the inlay layer and adjacent to or separated from the inlay layer; the supporting layer has a circular second bearing edge 18 extending toward the center of the camera through hole; after the lens protection ring is embedded in the camera through hole, the bottom of the lens protection ring is supported by the second bearing edge. That is, a layer is selected from the composite sheet of the bottom plate and is provided with a groove or convexity, which is used to engage with the lens protection ring and then be injection molded, and a layer is selected below the layer as a supporting bottom, which is supported from the bottom to wrap the lens protection ring, which not only strengthens the lens protection ring, but also increases the area of ​​injection molding.

[0036] It can be understood that the outer surface of the side wall of the lens protection ring is completely injection molded with the inner wall of the camera through hole. Figure 7 As shown, after the glass sheet is embedded in the lens protection ring, it is flush with the height of the bottom plate, and the corresponding product appearance effect is as follows Figure 2 shown.

[0037] The above is an explanation of the camera lens protection cover of the present invention, which is used to help understand the present invention. However, the implementation method of the present invention is not limited to the above-mentioned embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
