Description

Technical Field

[0001] This utility model relates to the field of mobile phone camera technology, specifically to a mobile phone camera lens structure using a waterproof and breathable membrane. Background Technology

[0002] The camera module of a smartphone is one of its most delicate components and is extremely sensitive to moisture and dust. Currently, common solutions to improve the waterproof performance of the camera area of ​​a mobile phone are to attach a waterproof and breathable membrane to the inside of the camera lens or decorative ring, or to use sealing rings or adhesive to seal the interface between the module and the phone casing.

[0003] However, these existing technologies have inherent flaws: First, by directly attaching the waterproof and breathable membrane to the inside of the lens or the cavity wall, the membrane itself becomes the only barrier against water and dust. If there are flaws in the adhesion edges or damage during assembly, moisture will directly penetrate and corrode the camera sensor, resulting in a high concentration of risk. Second, a simple gel sealing solution is difficult to effectively balance the pressure difference between the inside and outside of the phone. When the temperature changes, negative pressure is easily generated inside, which will slowly "draw" moisture into the device over a long period of time, or cause the sealant to fatigue and fail. Third, the light transmission and air pressure balancing functions are not distinguished and share a channel, which cannot fundamentally prevent the risk of moisture intrusion along the same path. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a mobile phone camera lens structure employing a waterproof and breathable membrane, comprising a lens, a lens decoration, and a lens mounting bracket. The lens is attached to the bottom of the lens decoration. The lens decoration has at least one light-transmitting hole and at least one air-venting hole for balancing air pressure. The waterproof and breathable membrane is located at the bottom of the air-venting hole, and a sealing membrane is located at the top of the air-venting hole. The waterproof and breathable membrane, the air-venting hole, and the sealing membrane together form an independent waterproof and breathable channel. The light-transmitting hole maintains optical transparency and is physically isolated from the waterproof and breathable channel.

[0005] Preferably, the lens decoration includes a first base and a second base located on the first base, and the light-transmitting hole and the vent hole penetrate the first base and the second base.

[0006] Preferably, the bottom of the first substrate is recessed inward to form a receiving groove, and the waterproof and breathable membrane is disposed in the receiving groove.

[0007] Preferably, the waterproof and breathable membrane is fixed in the receiving groove by an adhesive substance.

[0008] Preferably, a stepped structure is formed between the second substrate and the first substrate, and the height of the stepped structure is adapted to the thickness of the back cover of the mobile phone.

[0009] Preferably, the light-transmitting hole and the air-permeable hole extend upward along the vertical direction of the second substrate to form an extension portion.

[0010] Preferably, the lens mounting bracket has a mounting hole adapted to the extension, and the extension passes through the mounting hole.

[0011] Preferably, the lens mounting bracket and the lens decorative element are bonded together using an adhesive substance.

[0012] Preferably, the lens is attached to the bottom of the lens decoration using an adhesive material.

[0013] Preferably, the sealing film is spaced apart from the lens fixing bracket and is not in communication with it.

[0014] The above-described solution of this utility model has at least the following beneficial effects:

[0015] When a pressure difference exists between the inside and outside of the phone, air molecules can freely pass through the waterproof and breathable membrane at the bottom, achieving rapid pressure balance through a dedicated vent. This mechanism effectively eliminates the risk of moisture inhalation caused by pressure differences and reduces stress on the sealing material.

[0016] This structure provides two or more lines of defense against moisture intrusion:

[0017] The first line of defense (physical isolation): The light-transmitting holes and the air-transmitting holes are completely separated in structure, so that water vapor cannot enter directly through the light-transmitting holes;

[0018] The second line of defense (top seal): moisture attempting to enter from the outside through the vents is first blocked by the sealing membrane at the top.

[0019] The third line of defense (bottom layer protection): Even if there is very little residual moisture, it will be ultimately intercepted by the waterproof and breathable membrane at the bottom of the vents.

[0020] This "double-membrane sealing" structure, consisting of a sealing membrane and a waterproof and breathable membrane, completely seals off potential intrusion moisture in an independent channel, preventing it from reaching the internal components of the camera.

[0021] By physically isolating the light-transmitting channel and the air-permeable channel, and combining the redundant design of the double-membrane seal, multiple waterproof barriers are constructed, which greatly extends the water vapor intrusion path, transforms the waterproof risk from "single point failure" to "system-level protection", and significantly improves the long-term reliability of the camera module in harsh environments.

[0022] The independent waterproof and breathable channel is dedicated to air pressure equalization, responds quickly, and can eliminate the pressure difference between the inside and outside in time; at the same time, the isolation design of this channel from the internal components ensures that the air pressure equalization process itself will not pose any risk to the camera.

[0023] As a pure optical channel, the light-transmitting aperture is free from any film-like obstruction, ensuring 100% light intake and distortion-free image quality, fundamentally solving the problem of image quality being affected by film application.

[0042] The structure of a mobile phone camera lens using a waterproof and breathable membrane according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Please see Figures 1-6 In this embodiment, the lens includes a lens 1, a lens decoration 2, and a lens mounting bracket 3. The lens 1 is attached to the bottom of the lens decoration 2. The lens decoration 2 has at least one light-transmitting hole 4 for light transmission and at least one air-venting hole 5 for balancing air pressure. A waterproof and breathable membrane 6 is provided at the bottom of the air-venting hole 5, and a sealing membrane 7 is provided at the top of the air-venting hole 5. The waterproof and breathable membrane 6, the air-venting hole 5, and the sealing membrane 7 together form an independent waterproof and breathable channel. The light-transmitting hole 4 maintains optical transparency and is physically isolated from the waterproof and breathable channel.

[0044] When a pressure difference exists between the inside and outside of the phone, air molecules can freely pass through the waterproof and breathable membrane 6 at the bottom and quickly achieve pressure balance through the dedicated vent 5. This mechanism effectively eliminates the risk of moisture inhalation caused by pressure differences and reduces stress on the sealing material.

[0045] This structure provides two or more lines of defense against moisture intrusion:

[0046] The first line of defense (physical isolation): The light-transmitting hole 4 and the air-transmitting hole 5 are completely separated in structure, and water vapor cannot enter directly through the light-transmitting hole 4;

[0047] The second line of defense (top seal): Water vapor attempting to enter from the outside through the vent 5 is first blocked by the sealing membrane 7 at its top;

[0048] The third line of defense (bottom layer protection): Even if there is very little residual moisture, it will be ultimately intercepted by the waterproof and breathable membrane 6 at the bottom of the vent 5.

[0049] This "double-membrane sealing" structure, consisting of a sealing membrane 7 and a waterproof and breathable membrane 6, completely seals off potential intrusion moisture in an independent channel, preventing it from reaching the internal components of the camera.

[0050] By physically isolating the light-transmitting channel and the air-permeable channel, and combining the redundant design of the double-membrane seal, multiple waterproof barriers are constructed, which greatly extends the water vapor intrusion path, transforms the waterproof risk from "single point failure" to "system-level protection", and significantly improves the long-term reliability of the camera module in harsh environments.

[0051] The independent waterproof and breathable channel is dedicated to air pressure equalization, responds quickly, and can eliminate the pressure difference between the inside and outside in time; at the same time, the isolation design of this channel from the internal components ensures that the air pressure equalization process itself will not pose any risk to the camera.

[0052] As a pure optical channel, the light-transmitting aperture 4 is unobstructed by any film, ensuring 100% light intake and distortion-free imaging quality, fundamentally solving the problem of image quality being affected by film application.

[0053] In this embodiment, the lens decorative component 2 includes a first base 201 and a second base 202 located on the first base 201. The light-transmitting hole 4 and the vent hole 5 pass through the first base 201 and the second base 202. By setting the decorative component as the first base 201 and the second base 202, a clear and independent physical support platform is provided for the optical function, sealing function and assembly function. The first base 201 can focus on bottom sealing (such as accommodating the waterproof and breathable membrane 6 and attaching the lens 1), while the second base 202 can focus on the cooperation and appearance with external components (such as the back cover of a mobile phone and the fixing bracket), so that one component has multiple roles and greatly simplifies the overall structural design.

[0054] The light-transmitting hole 4 and the air-permeable hole 5 penetrate the first and second substrates 202, which means that the channels are processed and formed on a continuous path, fundamentally ensuring the straightness, concentricity and high precision of the relative position of the two channels; this avoids the misalignment and deviation that may exist in the split structure, and lays a reliable foundation for the subsequent precision assembly with the lens 1, sealing film 7 and fixing bracket, significantly improving the product yield.

[0055] The layered structure allows for the design of independent sealing features at different levels; for example, a bottom seal is formed between the first substrate 201 and the lens 1, a middle seal is formed between the second substrate 202 and the back cover of the phone, and the extension 204 can form a top seal with the fixed bracket, forming a multi-layer sealing barrier distributed along the Z-axis, which greatly enhances the overall structure's dustproof and waterproof depth defense capability.

[0056] The dual-substrate structure provides greater flexibility for industrial design; the second substrate 202 can serve as the exterior surface, using different materials, colors, and surface treatment processes (such as ceramic texture and metallic luster) from the first substrate 201 or the back cover of the phone, forming a rich sense of visual hierarchy and a high-end texture contrast.

[0057] In this embodiment, the bottom of the first substrate 201 is recessed inward to form a receiving groove 203, and the waterproof and breathable membrane 6 is disposed in the receiving groove 203. The receiving groove 203 provides a shape-matching natural limiting structure for the installation of the waterproof and breathable membrane 6, ensuring that the waterproof and breathable membrane 6 can be quickly and accurately positioned in the predetermined position during the assembly process, effectively preventing the sealing problem that may occur due to the offset of the pasting position, and greatly improving the consistency and reliability of the assembly process.

[0058] By embedding the waterproof and breathable membrane 6 within the receiving groove 203, with its surface lower than or flush with the bottom periphery plane of the first substrate 201, an efficient physical protective barrier is provided for the fragile functional membrane. This embedded design effectively prevents the membrane from being damaged by scratches or collisions with external tools or components during subsequent handling, transportation, or assembly, significantly improving production yield and component durability.

[0059] The structure of the receiving groove 203 increases the effective bonding area and wrapping depth between the waterproof and breathable membrane 6 and the substrate; the adhesive material can fully fill the space between the side wall of the groove and the edge of the membrane, forming a deeper and stronger three-dimensional wrapping seal, rather than a simple planar bond, which can more effectively resist water pressure impact and prevent colloidal creep and sealing interface failure caused by long-term use or environmental temperature changes.

[0060] The embedded design allows the bottom of the integrated waterproof and breathable membrane 6 to maintain a low and flat overall profile, which is beneficial for controlling the overall thickness of the camera module and provides favorable conditions for the thinner and lighter design of mobile phones, in line with the development trend of compactness and miniaturization of consumer electronics products.

[0061] In this embodiment, the waterproof and breathable membrane 6 is fixed in the receiving groove 203 by an adhesive substance; by utilizing the fluidity and filling properties of the adhesive substance, all micro gaps between the receiving groove 203 and the waterproof and breathable membrane 6 can be fully filled to form a complete and gapless sealing layer, which completely eliminates the potential path for water vapor to enter from the edge of the membrane and ensures the absolute sealing integrity of the waterproof and breathable channel entrance.

[0062] Using processes such as dispensing, spraying, or applying pre-formed adhesive films, it perfectly meets the process requirements of automated mass production. It is simple to operate, has good consistency, and a fast production cycle. It does not require complicated mechanical fastening steps, which significantly reduces labor and manufacturing costs.

[0063] The viscous material layer has good flexibility and elasticity, which can effectively absorb and disperse mechanical and thermal stress from the outside or inside the component, providing reliable buffer protection for the fragile waterproof and breathable membrane 6, preventing it from breaking due to stress concentration, thereby improving the durability of the entire component under harsh conditions such as vibration, impact and thermal cycling.

[0064] Furthermore, "adhesive material" is a broader concept that encompasses various types of adhesives (such as pressure-sensitive adhesives, hot melt adhesives, and UV-curable adhesives). This allows designers to select the most economical and suitable bonding solution based on the substrate material, weather resistance requirements, and production conditions, resulting in extremely high application adaptability.

[0065] In this embodiment, a stepped structure is formed between the second substrate 202 and the first substrate 201, and the height of the stepped structure is adapted to the thickness of the back cover of the mobile phone. By setting the step height to precisely match the thickness of the back cover of the mobile phone, it is ensured that after assembly, the surface of the second substrate 202 of the lens decoration part 2 can form a perfectly flush continuous plane with the outer surface of the back cover of the mobile phone, completely eliminating the visual sense of step difference and assembly gap, and significantly improving the overall aesthetics and smoothness of the back of the mobile phone.

[0066] The precisely fitted stepped structure fits tightly with the edge of the holes in the back cover, forming an important line of defense that directly blocks external pollutants. This effectively prevents dust, water droplets, and other pollutants from the front of the phone from directly impacting or penetrating the main sealing interface between the lens 1 and the decorative parts, reducing the risk of contamination and corrosion of the core sealing area.

[0067] The stepped design significantly increases the contact and support area between the lens decorative piece 2 and the back cover of the phone, making the installation foundation of the entire camera lens 1 structure more stable and reliable. It can better disperse and resist external squeezing or impact forces, and prevent the internal precision sealing system from being damaged due to structural deformation caused by external forces.

[0068] The pre-formed, adaptable stepped structure provides an intuitive physical positioning and limiting reference for the assembly process on the production line, enabling the phone back cover to be installed quickly and accurately in the predetermined position. This simplifies the alignment process, reduces human assembly errors, and thus improves the efficiency of mass production and the first-pass yield of the product.

[0069] In this embodiment, the light-transmitting hole 4 and the air-permeable hole 5 extend upward along the vertical direction of the second substrate 202 to form an extension 204; the extension 204 constitutes a raised three-dimensional guide structure, which can achieve quick and accurate alignment and insertion when assembled with subsequent components such as the lens fixing bracket 3, effectively avoiding horizontal offset or rotational misalignment that may occur during the assembly process, greatly improving assembly accuracy and production efficiency, and ensuring the coaxiality of the optical device and the integrity of the airtight channel;

[0070] The extension 204 structure increases the height of the channel sidewalls, thereby significantly lengthening the path that moisture and dust would have to bypass to prevent intrusion. This provides ample room for applying sealant or installing sealing rings on the sidewalls or ends of the extension 204, facilitating the formation of a deeper and more robust three-dimensional sealing barrier and greatly improving the long-term dust and water resistance of this critical interface.

[0071] The upwardly protruding extension 204 structure provides a physical protective wall for the sealing membrane 7 at its end or the internal channels, making it less susceptible to lateral scratches or direct impacts during assembly and daily use, reducing the risk of damage to the sealing membrane 7 and the waterproof and breathable membrane 6, and enhancing the overall mechanical strength and durability of the component.

[0072] The extension 204 is integrally formed with the lens decoration 2 body, which vertically integrates the complex airtight channels and optical channels in three-dimensional space, rather than laying them out on a plane. This vertical design saves valuable planar layout space and is conducive to achieving a more compact and thinner industrial design for the camera module and even the whole machine.

[0073] In this embodiment, the lens mounting bracket 3 has an assembly hole 301 that matches the extension 204, and the extension 204 passes through the assembly hole 301. The design of the assembly hole 301 matching the extension 204 provides a physical fixing method with self-guiding function, which can automatically correct position deviations during assembly and ensure that the components are installed quickly and accurately. This mechanical interlocking structure provides a strong anchor point for the entire lens 1 assembly, effectively enhancing its structural stability under harsh conditions such as vibration and impact.

[0074] The precise fit between the mounting hole 301 and the extension 204 provides uniform support for the connection between the lens decoration 2 and the fixed bracket. This uniform force distribution avoids local stress concentration, ensures consistent compression of the viscous material sealing layer, and significantly improves the sealing uniformity and long-term reliability at the interface.

[0075] The extension 204, which passes through the assembly hole 301, forms a physical barrier that effectively prevents external foreign objects from directly contacting and damaging the internal sealing membrane 7 and waterproof and breathable membrane 6. This protective design reduces the risk of seal failure due to external factors and improves the product's durability in complex usage environments.

[0076] This detachable mechanical connection method enables modular design of the product; when the camera module needs to be replaced or repaired, the bracket and decorative parts can be separated relatively easily, significantly reducing the difficulty and cost of after-sales maintenance. This advantage is not available in traditional methods that rely entirely on adhesive materials for connection.

[0077] In this embodiment, the lens mounting bracket 3 and the lens decorative part 2 are bonded together with an adhesive substance. The fluidity and filling properties of the adhesive substance can fully fill the assembly gap between the lens mounting bracket 3 and the lens decorative part 2, forming a complete and uninterrupted sealing layer. This completely eliminates any possibility of moisture and dust intruding from the interface between the two, greatly improving the sealing reliability of the overall structure.

[0078] After curing, the adhesive material can form a strong connection on the entire contact surface, which significantly improves the overall structural rigidity and connection strength of the component, making the lens mounting bracket 3 and the lens decorative part 2 work together as a whole, effectively resisting torsion and vibration, and ensuring the long-term stability of the optical element position.

[0079] The viscous material layer has good flexibility and elasticity, which can effectively absorb and disperse mechanical shocks and thermal stresses from the outside, providing reliable buffer protection for the delicate internal components of the camera and preventing structural damage or optical misalignment caused by stress concentration.

[0080] The bonding process eliminates the need for complex mechanical fastening structures, making it particularly suitable for automated mass production. Assembly can be completed quickly through processes such as dispensing and spraying adhesives. It is highly adaptable to components of different shapes and sizes, reducing manufacturing complexity and production costs.

[0081] In this embodiment, the lens 1 is attached to the bottom of the lens decoration 2 by an adhesive material. The adhesive material ensures that the lens 1 and the light-transmitting hole 4 on the lens decoration 2 maintain precise concentricity and parallelism, providing an accurate and stable optical reference surface for the optical imaging system. This effectively avoids imaging quality problems caused by the offset or tilt of the lens 1 and ensures the optical performance of the camera module.

[0082] The viscous material can continuously and completely fill all the microscopic gaps between the periphery of the lens 1 and the decorative substrate, forming a 360-degree ring-shaped sealing wall without dead angles, completely blocking the path of moisture and dust from the edge of the lens 1 into the camera, and significantly improving the sealing reliability of this key interface.

[0083] The viscous material layer has excellent elasticity and flexibility, which can effectively absorb and disperse mechanical shocks and thermal stresses from the outside, providing reliable mechanical buffer protection for the brittle optical lens 1, preventing it from breaking due to stress concentration, and reducing the impact of vibration on imaging stability.

[0084] The lens is fixed by bonding process 1 without the need to design a complicated mechanical clamping structure, which is particularly suitable for automated mass production. Assembly can be completed quickly by precise dispensing or attaching pre-formed glue frames. It has high production efficiency, strong process adaptability, and effectively reduces manufacturing complexity and production costs.

[0085] In this embodiment, the sealing film 7 is spaced apart from the lens fixing bracket 3 and is not connected; by maintaining the physical distance between the sealing film 7 and the lens fixing bracket 3, it is ensured that any mechanical stress generated during the assembly process or when subjected to external impact cannot be directly transmitted to the fragile sealing film 7, completely avoiding the problem of the sealing film 7 falling off, breaking or failing to seal due to bracket squeezing, deformation or vibration, and greatly improving the long-term reliability of the sealing structure.

[0086] This space, together with the vent 5 below, forms a closed "waterproof air chamber." This design provides double protection against moisture intrusion: it must first break through the top sealing membrane 7, and after entering the air chamber, it still needs to break through the bottom waterproof and breathable membrane 6 to enter the phone's interior. This air chamber design transforms single-point defense into a systemic defense with depth, significantly extending the moisture intrusion path and doubling the waterproof reliability.

[0087] Since the sealing film 7 does not directly contact the lens mounting bracket 3, it effectively blocks the direct transmission of the thermal expansion and contraction effect of the metal bracket (which usually has good thermal conductivity) caused by changes in ambient temperature to the sealing film 7. This prevents shear stress caused by the difference in thermal expansion coefficients between the two materials, protects the integrity of the bonding interface of the sealing film 7, and improves the durability of the product in high and low temperature environments.
