Description

Technical Field

[0001] This application relates to the field of mobile phone accessory technology, and in particular to a lens protective film and lens coating assembly for protecting the rear camera of a mobile phone. Background Technology

[0002] With the rapid development of smartphone technology, mobile phone photography functions have become increasingly powerful, making the rear camera one of the key components of a mobile phone. Since the rear camera is usually exposed to the outside of the phone, it is highly susceptible to damage from various factors during daily use, such as scratches, impacts, and dust accumulation. This damage not only affects the lens's optical performance and reduces image quality, but in severe cases, it can even lead to lens failure, affecting the normal use of the phone. Therefore, providing effective protective measures for the mobile phone's rear camera is particularly important.

[0003] Currently, the main method for protecting the rear camera of mobile phones is through lens protectors. Lens protectors can, to some extent, isolate the lens from direct contact with external factors, thus protecting it. Existing lens protector technology mainly falls into two categories, but both have significant drawbacks: The first method involves directly applying an eagle-eye film to each of the phone's rear cameras. However, this requires multiple eagle-eye films for each camera, and because the contact area between the film and the lens is relatively small, the film is prone to peeling off.

[0004] The second method involves attaching multiple lens protectors to a panel using adhesive or a single molding process, then bonding the entire panel to the rear camera area of ​​the phone. Currently, this type of lens protector mostly uses panel materials such as glass or metal. Due to the high hardness of these materials, if the phone is dropped, the hard panel will directly transmit the impact force to the lens, potentially causing damage. Furthermore, the hard panel cannot adhere perfectly to the phone, leading to peeling or detachment over time.

[0005] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0006] In view of the above problems, this utility model proposes a lens protective film, which aims to solve the technical problems that lens films with hard panels are prone to damaging the lens and cannot be fully adhered to the mobile phone.

[0007] To achieve the above objectives, the lens protective film proposed in this utility model includes a flexible panel and at least one eagle-eye lens film assembly: The flexible panel includes a flexible film layer and a double-sided adhesive layer stacked together. The flexible film layer has a first through hole for a lens to pass through, and the double-sided adhesive layer has a second through hole corresponding to the first through hole. The eagle eye lens assembly includes a lens housing and a light-transmitting lens. The lens housing is adapted to be mounted on the periphery of the lens. The lens housing has a lens hole. The light-transmitting lens covers and is fixed to the lens hole. The lens housing is adapted to be embedded in the first through hole and is bonded to the double-sided adhesive layer. The hardness of the flexible panel is less than that of the lens mount housing.

[0008] In one embodiment, the diameter of the second through hole is smaller than the outer diameter of the lens housing, so that the double-sided adhesive layer protrudes from the inner periphery of the first through hole to form an adhesive ring, and the end face of the lens housing is bonded to the adhesive ring.

[0009] In one embodiment, the width of the adhesive ring protruding from the periphery of the first through hole is greater than or equal to the end face width of the lens mount housing.

[0010] In one embodiment, the thickness of the double-sided adhesive layer is less than the thickness of the flexible film layer.

[0011] In one embodiment, the double-sided adhesive layer includes a substrate layer, a first adhesive layer covering the side of the substrate layer facing the flexible film layer, and a second adhesive layer covering the side of the substrate layer away from the flexible film layer; the thickness of the first adhesive layer is greater than the thickness of the second adhesive layer.

[0012] In one embodiment, both the substrate layer and the flexible film layer are made of PET material, the first adhesive layer is made of AB adhesive, and the second adhesive layer is made of removable adhesive.

[0013] In one embodiment, the flexible panel is a rounded rectangle, with three first and two through holes, and three eagle-eye lens assemblies, each corresponding to one of the three first through holes; two eagle-eye lens assemblies are provided near the edge of the flexible panel along its length, and the two eagle-eye lens assemblies are arranged side by side along the width of the flexible panel, with another eagle-eye lens assembly located in the middle of the flexible panel.

[0014] This utility model also proposes a lens coating assembly, including a locator and a lens protective film as described in any of the above embodiments. The locator has a positioning groove, and the bottom surface of the positioning groove has a positioning hole. The lens protective film is adapted to be embedded in the positioning groove, and the eagle-eye lens film assembly of the lens protective film is correspondingly embedded in the positioning hole.

[0015] In one embodiment, the locator includes a rigid frame and a flexible positioning film, the flexible positioning film being detachably bonded to one side of the rigid frame to enclose the positioning groove with the inner cavity of the rigid frame, and the positioning hole being formed on the flexible positioning film.

[0016] In one embodiment, the rigid frame has a notch at the end away from the eagle-eye lens film assembly, and the lens protective film further includes a release film that is detachably bonded to the side of the double-sided adhesive layer of the lens protective film facing away from the flexible panel. The release film has a lug that protrudes from the flexible panel and is placed within the notch.

[0017] This novel lens protector utilizes a flexible panel to mount an eagle-eye lens film assembly. The flexible panel's hardness is less than that of the lens mount housing, which is made of a harder material like metal. This provides comprehensive protection for the individual rear camera, preventing lens damage. The flexible panel, made of a flexible material, adheres perfectly to the back of the phone. Compared to a rigid panel, this allows for a more seamless fit, significantly improving the adhesion and preventing the panel from warping or detaching after prolonged use. It also effectively prevents dust intrusion, enhancing the user experience. Furthermore, the flexible panel's resilience absorbs impact energy, reducing direct impact damage to the lens. In addition, the flexible panel is thinner and lighter, reducing the overall thickness of the phone's lens area and maintaining a slim, bare-phone feel. Attached Figure Description

[0026] This utility model proposes a lens protective film.

[0027] In this embodiment of the utility model, please refer to Figure 1 , Figure 2 and Figure 6The lens protective film 100 includes a flexible panel 110 and at least one eagle-eye lens film assembly 120. The flexible panel 110 includes a flexible film layer 111 and a double-sided adhesive layer 113 stacked together. The flexible film layer 111 has a first through hole 112 for the lens to pass through, and the double-sided adhesive layer 113 has a second through hole 114 corresponding to the first through hole 112. The eagle-eye lens film assembly 120 includes a lens housing 121 and a light-transmitting lens 123. The lens housing 121 is adapted to be installed around the lens. The lens housing 121 has a lens hole 122, and the light-transmitting lens 123 covers and is fixed to the lens hole 122. The lens housing 121 is adapted to be embedded in the first through hole 112 and is bonded to the double-sided adhesive layer 113. The hardness of the flexible panel 110 is less than the hardness of the lens housing 121.

[0028] In this embodiment, the flexible panel 110 refers to a bendable and deformable plate-like structure. The flexible film layer 111 can be made of a flexible substrate, such as PET (polyester) or PP (polypropylene). The double-sided adhesive layer 113 can be a substrate-free double-sided adhesive or a substrate-supported double-sided adhesive. One side of the double-sided adhesive layer 113 is firmly bonded to the flexible panel 110, and the other side is used for removable adhesive bonding to the back of the mobile phone. The thickness of the flexible film layer 111 and the double-sided adhesive layer 113 can be selected and designed according to actual needs, and is not specifically limited here. The shape of the flexible panel 110 can be designed according to different mobile phone models; for example, the flexible panel 110 can be set as a rounded square, a rounded rectangle, etc.

[0029] The eagle-eye lens assembly 120 is used to protect the rear camera of a mobile phone. The number and size of the eagle-eye lens assemblies 120 can be designed according to the mobile phone model; for example, there can be two, three, or four eagle-eye lens assemblies 120. When the mobile phone has at least two rear cameras, the arrangement of the first through-holes 112 can also be set according to the rear camera of different mobile phone models. Multiple eagle-eye lens assemblies 120 are embedded in multiple first through-holes 112 in a one-to-one correspondence.

[0030] Lens housing 121 refers to a structure used to protect the outer periphery of a mobile phone camera. Lens housing 121 is generally annular in shape and is used to fit and fasten around the mobile phone lens. The peripheral wall and / or end face of lens housing 121 can be bonded to double-sided adhesive layer 113 to ensure a stable connection between the eagle-eye lens assembly 120 and the flexible panel 110. A light-transmitting lens 123 is attached to the camera to protect the mobile phone camera. Lens housing 121 can be made of a high-hardness material such as metal or polymer fiber to surround the lens periphery. The light-transmitting lens 123 can be made of tempered glass, sapphire glass, PC (polycarbonate), or other light-transmitting sheets to protect the lens surface of the camera. The light-transmitting lens 123 can be bonded to the top surface of lens housing 121 via double-sided adhesive rings, and double-sided adhesive rings are also bonded to the inner bottom surface of lens housing 121 to bond lens housing 121 to the mobile phone lens.

[0031] This utility model's lens protective film 100 utilizes a flexible panel 110 to mount an eagle-eye lens film assembly 120. The flexible panel 110 has a lower hardness than the lens housing 121, meaning the lens housing 121 is made of a harder material like metal, providing comprehensive protection for the single rear camera and preventing lens damage. The flexible panel 110, made of a flexible material, adheres to the back of the phone. Compared to a rigid panel, it allows for a more seamless fit, significantly improving the adhesion and preventing the panel from warping or detaching after prolonged use. This effectively prevents dust intrusion and enhances the user experience. Furthermore, the flexible panel 110's toughness absorbs impact energy, reducing direct impact damage to the lens. In addition, the flexible panel 110 is thinner and lighter, reducing the overall thickness of the phone's lens area and ensuring a slim, bare-phone feel.

[0032] In one embodiment, please refer to the following: Figure 3 and Figure 4 The diameter of the second through hole 114 is smaller than the outer diameter of the lens housing 121, so that the double-sided adhesive layer 113 protrudes from the inner periphery of the first through hole 112 to form an adhesive ring 115, and the end face of the lens housing 121 is bonded to the adhesive ring 115.

[0033] Understandably, if the peripheral wall of the lens housing 121 is bonded to the inner peripheral wall of the second through hole 114, an additional positioning structure is needed to axially position the lens housing 121. Furthermore, the manufacturing precision of the second through hole 114 is high, and bonding instability is likely to occur. In this embodiment, the diameter of the second through hole 114 is smaller than the outer diameter of the lens housing 121, while the inner diameter of the first through hole 112 is essentially the same as the outer diameter of the lens housing 121. This allows the inner peripheral edge of the second through hole 114 to protrude beyond the inner peripheral edge of the first through hole 112, forming an bonding ring 115. By bonding the end face of the lens housing 121 to the bonding ring 115, compared to bonding the peripheral wall of the lens housing 121 to the inner peripheral wall of the second through hole 114, the bonding ring 115 can both axially limit the lens housing 121 and bond the end face of the lens housing 121 in a circle, making the bonding between the lens housing 121 and the flexible panel 110 more stable and reliable.

[0034] Furthermore, such as Figure 4 As shown, the width of the adhesive ring 115 protruding from the periphery of the first through hole 112 is greater than or equal to the end face width of the lens housing 121. That is, the inner diameter of the second through hole 114 is less than or equal to the inner diameter of the lens housing 121. In this way, the entire end face of the lens housing 121 can be bonded to the double-sided adhesive layer 113, maximizing the bonding area of ​​the end face of the lens housing 121, thereby improving the adhesion between the lens housing 121 and the flexible panel 110, and further enhancing the bonding stability between the eagle lens diaphragm assembly 120 and the flexible panel 110.

[0035] In one embodiment, the thickness of the double-sided adhesive layer 113 is less than the thickness of the flexible film layer 111. If the thickness of the double-sided adhesive layer 113 is greater than or equal to the thickness of the flexible panel 110 layer, resulting in a larger thickness of the double-sided adhesive layer 113, then the double-sided adhesive layer 113 is prone to adhesive overflow, and the overall thickness of the flexible panel 110 increases, which is not conducive to the product's thinness. Therefore, by making the thickness of the double-sided adhesive layer 113 less than the thickness of the flexible film layer 111, the double-sided adhesive layer 113 can achieve reliable adhesion while avoiding adhesive overflow, and the entire flexible panel 110 is made thinner and lighter.

[0036] Furthermore, such as Figure 7 As shown, the double-sided adhesive layer 113 includes a substrate layer 116, a first adhesive layer 117 covering the side of the substrate layer 116 facing the flexible film layer 111, and a second adhesive layer 118 covering the side of the substrate layer 116 away from the flexible film layer 111; the thickness of the first adhesive layer 117 is greater than the thickness of the second adhesive layer 118.

[0037] In this embodiment, the substrate layer 116 can be made of transparent materials such as PET (polyester) or PP (polypropylene) to provide support and coating surfaces for the first adhesive layer 117 and the second adhesive layer 118. The first adhesive layer 117 is used to bond and fix the substrate layer 116 and the flexible film layer 111, and the second adhesive layer 118 is used to bond and fix the flexible panel 110 and the back of the mobile phone. Specifically, the first adhesive layer 117 and the second adhesive layer 118 are made of different materials; for example, the first adhesive layer 117 is made of AB glue, and the second adhesive layer 118 is made of removable adhesive. By making the thickness of the first adhesive layer 117 greater than the thickness of the second adhesive layer 118, a stable and reliable connection between the double-sided adhesive layer 113 and the flexible film layer 111 can be ensured.

[0038] Furthermore, both the substrate layer 116 and the flexible film layer 111 are made of PET (polyester), the first adhesive layer 117 uses AB adhesive, and the second adhesive layer 118 uses removable adhesive. This allows PET material, as the substrate for the double-sided adhesive layer 113, to have strong adhesion, high transparency, and good wrinkle resistance, resulting in a more perfect fit between the flexible panel 110 and the back of the phone. The flexible film layer 111, made of PET material, offers advantages such as high transparency, thin and lightweight fit, resistance to fingerprints and oil stains, and a bare-phone feel.

[0039] AB glue, also known as two-component mixed curing adhesive, is a two-component adhesive composed of acrylic, epoxy, or polyurethane components. It features high bonding strength, chemical resistance, water resistance, and temperature resistance. Using AB glue for the first adhesive layer 117 ensures high adhesion and a stable and reliable connection between the double-sided adhesive layer 113 and the flexible film layer 111. Removable adhesive is an adhesive with removable properties. Specifically, pressure-sensitive adhesive can be used. By using removable adhesive for the second adhesive layer 118, the flexible panel 110 is bonded to the back of the phone via removable adhesive. This allows the lens protective film 100 to be relatively easily removed after bonding, leaving no residue or traces. To ensure the overall thinness of the lens protective film 100, specifically, the sum of the thicknesses of the flexible film layer 111 and the double-sided adhesive layer 113 is less than or equal to 0.6 mm.

[0040] In one embodiment, such as Figure 1 and Figure 5 As shown, the flexible panel 110 is a rounded rectangle with three first through holes 112 and three second through holes 114. Three eagle-eye lens assemblies 120 are provided and are installed in the three first through holes 112 respectively. Two eagle-eye lens assemblies 120 are provided near the edge of the flexible panel 110 in the length direction and are arranged side by side in the width direction of the flexible panel 110. Another eagle-eye lens assemblies 120 is located in the middle of the flexible panel 110.

[0041] In this embodiment, the flexible panel 110 is a rounded rectangle, which can be adapted to mobile phones with rounded rectangular lens areas. Three eagle-eye lens assemblies 120 correspond one-to-one with the three independent rear cameras of the mobile phone, providing corresponding protection for the cameras. The arrangement of the three eagle-eye lens assemblies 120 can better accommodate the cameras of specific mobile phone models, providing more reliable protection for the rear cameras of that mobile phone.

[0042] This utility model also proposes a lens coating assembly, such as Figures 8 to 13 As shown, the lens coating assembly includes a locator 200 and a lens protective film 100. The locator 200 has a positioning groove 230, and the bottom surface of the positioning groove 230 has a positioning hole 221. The lens protective film 100 is adapted to be embedded in the positioning groove 230, and the eagle-eye lens film assembly 120 of the lens protective film 100 is correspondingly embedded in the positioning hole 221. The specific structure of the lens protective film 100 is as described in the above embodiments. Since this lens coating assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0043] In this embodiment, the outer contour shape of the locator 200 can be varied; for example, the outer contour shape can be set to be the same as or different from the outer contour shape of the flexible panel 110. For ease of positioning, the outer contour shape of the locator 200 can optionally be the same as the outer contour shape of the lens protective film 100. The positioning groove 230 is used for fitting and embedding into the protruding area of ​​the rear camera of the mobile phone. The positioning hole 221 is used for positioning the eagle-eye lens film assembly 120. The position and number of the positioning holes 221 correspond one-to-one with the position and number of the eagle-eye lens film assembly 120. In use, the positioning groove 230 of the locator 200 is aligned with the protruding area where the rear camera of the mobile phone is located, so that the locator 200 is positioned and fastened to the outer periphery of the protruding area. Then, the lens protective film 100 is pressed to stably adhere to the rear camera area of ​​the mobile phone. By using the locator 200 to install and position the flexible panel 110, rapid film application can be achieved without displacement during application, thus improving application efficiency and accuracy.

[0044] In one embodiment, please refer to Figures 11 to 13 The positioner 200 includes a rigid frame 210 and a flexible positioning film 220. The flexible positioning film 220 is detachably bonded to one side of the rigid frame 210 to form a positioning groove 230 by surrounding the inner cavity of the rigid frame 210. The positioning hole 221 is formed on the flexible positioning film 220.

[0045] In this embodiment, the rigid frame 210 can be made of rigid materials such as rigid plastic or metal, while the flexible positioning film 220 can be made of flexible plastic materials such as PET or PP. By giving the locator 200 a flexible positioning film 220, when the locator 200 is fastened to the mobile phone lens area, the user can press the flexible positioning film 220 to make the flexible panel 110 fit more closely to the back of the mobile phone. Since the flexible positioning film 220 is a flexible material, it can be deformed to make the fit of the flexible panel 110 more precise. The flexible positioning film 220 and the rigid frame 210 can be separably bonded. After positioning, the flexible positioning film 220 can be removed first, and then the unfitted areas of the flexible panel 110 can be smoothed out. After the lens protective film 100 is fully adhered, the rigid frame 210 can be removed. This further improves the accuracy of the film application.

[0046] In one embodiment, the rigid frame 210 has a notch 211 at the end away from the lens film assembly 120. The lens protective film 100 also includes a release film 130, which is detachably bonded to the side of the double-sided adhesive layer 113 of the lens protective film 100 facing away from the flexible panel 110. The release film 130 has a lug 131 protruding from the flexible panel 110 and positioned within the notch 211. The detachable bonding of the release film 130 to the side of the double-sided adhesive layer 113 of the lens protective film 100 facing away from the flexible panel 110 prevents dust from contaminating the exposed adhesive layer of the lens protective film 100 and reducing its adhesiveness. The lug 131 is for the user to grip with their fingers to facilitate tearing off the release film 130. The notch 211 on the rigid frame 210 can accommodate the lug 131 of the release film, allowing the entire lens film assembly to be better accommodated within the positioning groove 230.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
