Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a positioning device for assisting in the installation of a mobile phone lens protection plate, which also has a packaging protection function. Background Technology

[0002] The installation and protection of lens protection plates in the use of electronic devices such as smartphones have the following technical defects:

[0003] Insufficient ease of operation: Lens protection plates are usually only 0.1-1.5mm thick, thin and light, and lack a grip structure, making it difficult to accurately position them during manual installation, and they are prone to displacement due to hand tremors;

[0004] Decreased adhesion reliability: Traditional installation methods require direct contact with the adhesive surface of the lens protection plate, and the adhesive layer is easily contaminated by finger sweat, dust, etc., which increases the risk of the plate falling off after being pasted.

[0005] High packaging costs: In existing technologies, lens protection plates require separate cushioning packaging materials (such as bubble wrap, anti-static bags, etc.) for transportation or storage, which increases production costs and resource consumption.

[0006] To address this issue, this utility model provides a lens protection plate auxiliary positioner, which systematically solves the aforementioned technical problems through an innovative structural design that integrates positioning clamping, adhesive surface isolation, and fixed packaging functions. Utility Model Content

[0007] This invention provides a lens protection plate auxiliary device that integrates positioning, fixing and packaging functions, enabling precise installation, avoiding contamination, and improving transportation safety.

[0008] This utility model provides a lens protection plate auxiliary locator, including a locator body. The locator body has a recessed center forming a receiving groove. A spring tab is located on the side of the receiving groove, and a protrusion is provided on the side of the spring tab near the receiving groove. When the lens protection plate is placed in the receiving groove, the spring tab secures the lens protection plate through the protrusion. The elastic clamping force of the spring tab and the frictional force of the protrusion work together to fix the lens protection plate in the receiving groove. The receiving groove provides a preset installation position for the lens protection plate, eliminating the need for manual angle adjustment. Users can directly align the locator with the phone lens to complete the fitting, improving installation efficiency.

[0009] Further description of the aforementioned solution: It also includes a release film, which is attached to the adhesive surface of the lens protector. The adhesive force between the release film and the lens protector is less than the frictional force between the lens protector and the spring clip. Because the adhesive force is less than the frictional force of the spring clip, the lens protector remains fixed when the release film is removed, preventing displacement of the lens protector due to the film removal action and ensuring installation accuracy. No direct contact with the lens protector is required during installation, meeting the requirements for dust-free installation.

[0010] Further description of the aforementioned solution: The edge of the locator body is provided with a notch to facilitate the user to peel off the release film.

[0011] Further description of the aforementioned solution: The receiving groove is provided with a plurality of lens clearance holes, and the recessed depth of the receiving groove is adapted to the thickness of the lens protection plate to ensure that the lens protection plate is flat with the surface of the locator body after placement.

[0012] Further description of the aforementioned solution: A decorative film is also provided on the surface of the locator body located on the other side of the receiving groove. The decorative film is transparent at the lens clearance hole. The decorative film can be printed with brand logos, patterns, or installation instructions to enhance product recognition and aesthetics, meeting the appearance design requirements of the consumer market; and preventing dust and liquid from seeping into the lens clearance hole during transportation.

[0013] Further description of the aforementioned solution: A long, narrow deformation groove is formed on the side of the receiving slot, and a spring piece is positioned between the deformation groove and the receiving slot. The deformation groove provides the spring piece with lateral elastic deformation space, allowing the spring piece to flexibly conform to the lens protection plate through the deformation groove.

[0014] Further description of the aforementioned solution: A deformation groove is also provided on the upper or lower side of the receiving groove, and a spring piece is positioned between the deformation groove and the receiving groove. Combined with the side deformation groove, a bidirectional elastic fixation of the lens protection plate in both the lateral and longitudinal directions is achieved.

[0015] Further description of the aforementioned solution: The release film also adheres to the surface of the locator body, securing the lens protection plate in place. The release film serves dual functions of "adhesive surface protection" and "packaging fixation," eliminating the need for additional packaging materials, thus reducing production costs and environmental pollution. Users do not need to transfer the protection plate; after unpacking, installation is completed directly through the locator, reducing intermediate steps and improving ease of use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention uses a spring clip and a protrusion to elastically clamp the lens protection plate, achieving positioning and stable installation and avoiding manual alignment deviations. The release film adheres to the adhesive surface with an adhesive force less than the friction of the spring clip, preventing the protection plate from shifting when the film is peeled off, thus preventing fingers from contaminating the adhesive layer and improving adhesion reliability. The notch at the edge of the locator facilitates the peeling off of the release film, optimizing the user experience.

[0018] The receiving slot is equipped with lens clearance holes and is adapted to the thickness of the protective plate to ensure a flat surface, which not only avoids obstructing the lens but also facilitates transportation and stacking; the transparent part of the decorative film ensures optical performance, while the remaining areas can be printed with patterns to enhance aesthetics.

[0019] It integrates positioning, fixing, and packaging functions, reducing additional packaging costs. It is easy and efficient to operate, simple in structure and easy to mass-produce. It combines accuracy, protection and economy, and is suitable for various electronic device lens protection scenarios. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1 to 8 As shown, the lens protection plate auxiliary positioner provided by this utility model is suitable for the installation and transportation protection of lens protection plates of electronic devices. Its core structure includes a positioner body 1, an elastic clamping structure, and a release film 3. The components are precisely matched to achieve integrated functions.

[0031] The locator body 1 is made of transparent polypropylene (PP) material, molded by injection molding or CNC precision carving, and has a rectangular plate structure with dimensions suitable for mainstream mobile phone lens module areas. A recessed groove 11 is formed in the center of the locator body 1. The depth of the groove 11 is designed to be 0.5-2mm, precisely fitting the lens protection plate 2. This ensures that the upper surface of the lens protection plate 2 is flush with the surface of the locator body 1 after insertion, facilitating transportation and stacking while preventing obstruction of the lens view during installation. A notch 15 is provided on the edge of the locator body 1, allowing users to peel off the release film 3 along a preset direction by hooking their fingernail into the notch 15, avoiding contact with the adhesive surface of the lens protection plate 2.

[0032] like Figure 1 As shown, a spring piece 12 integrally formed with the locator body 1 is provided on the side of the receiving groove 11. The spring piece 12 is a thin-walled polypropylene structure with a thickness of 0.1-1.5mm, which has both rigid support and elastic deformation capability. The side of the spring piece 12 near the receiving groove 11 has evenly distributed protrusions, the height of the protrusions 121 is 0.05-0.15mm, and the surface roughness is controlled at Ra1.6-3.2μm, so as to achieve stable clamping by increasing the static friction with the lens protection plate 2.

[0033] In some embodiments, such as Figure 2 As shown, a long strip-shaped deformation groove 14 is provided on the side of the receiving groove 11, with a groove width of 1-2mm, allowing the spring piece 12 to swing laterally by ±0.2mm; a longitudinal deformation groove 14 can be provided on the upper or lower side, which cooperates with the transverse deformation groove 14 to form an elastic support, realizing bidirectional clamping of the lens protection plate 2, with a clamping force range of 0.5-1.5N.

[0034] The release film 3 is made of PET material with a thickness of 30-500μm, with an organic silicone release agent coated on the bottom surface. The adhesion force between the release film 3 and the adhesive surface of the lens protection plate 2 is controlled at 5-10g / 25mm. At the same time, the static friction force between the lens protection plate 2 and the raised spring 12 is measured to be 15-20g / 25mm, ensuring that the lens protection plate 2 remains fixed when the film is peeled off. The edge of the release film 3 extends 1-2mm beyond the edge of the lens protection plate 2 and is temporarily fixed to the surface of the locator body 1 through micro-adhesive dots, with an adhesion force of <5g / 25mm, forming a closed packaging structure. This eliminates the need for additional bubble wrap or anti-static bags, reducing packaging costs by more than 30%. During installation, the user hooks the edge of the release film 3 through the notch 15 and peels it off at a uniform speed at a 45° angle. Because the adhesion force is less than the friction force of the spring 12, the lens protection plate 2 does not shift during the peeling process.

[0035] The bottom of the receiving groove 11 has a lens clearance hole 13 corresponding to the lens protection plate 2. The hole diameter is 0.2-0.5mm larger than the actual diameter of the lens, and the edge is rounded to R0.1-R0.2mm. The front of the locator body 1 is covered with a PET decorative film 4 with a thickness of 50-80μm. The surface is printed with the brand logo and installation guide pattern through screen printing. A transparent window with a light transmittance of ≥90% is set at the position corresponding to the clearance hole 13, which not only ensures optical performance but also enhances product recognition.

[0036] During production, such as Figure 5 , 6 As shown in Figure 7, the lens protection plate 2 is embedded in the receiving groove 11, and the side spring 12 elastically clamps the lens protection plate 2 through the protrusion 121; then, the release film 3 is flatly attached to the adhesive surface of the lens protection plate 2, while the edge of the release film 3 is slightly adhered to the surface of the locator body 1; finally, the decorative film 4 is attached to the front to complete the overall encapsulation. This packaging structure can withstand a stacking pressure of 50-100 kPa, and after a 1.5m drop test, the lens protection plate 2 showed no displacement or detachment.

[0037] When users use it, such as Figure 7 , 8 As shown, peel off the release film 3, pinch the side of the locator body 1 with your fingers, align it with the lens on the back of the phone, and attach the lens protection plate 2 to the front of the phone. After attachment, since part of the locator body 1 is suspended at the edge of the phone, the locator body 1 and the lens protection plate 2 can be easily separated.

[0038] In summary, this invention integrates the positioning, fixing, and packaging functions of the lens protection plate 2 through the elastic clamping of the side spring piece 12 of the receiving groove 11, the adhesive force control of the release film 3, and the coordinated design of the precise receiving groove 11. Its transparent body facilitates visual alignment, and the optimized design of the notch 15 and the release film 3 enhances ease of operation. This positioner can be widely used in scenarios such as smartphone and tablet camera displays, and is particularly suitable for automated production lines and the consumer retail market, combining technological innovation with industrial application value.
