Description

Technical Field

[0001] This utility model relates to the field of police light lens assembly technology, specifically to an embedded police light lens device. Background Technology

[0002] In existing technologies, the method of fixing the lens to the housing of a warning light directly affects its stability and durability, which is an important warning device. Currently, the lens and housing of embedded warning lights are typically fixed in the following two ways:

[0003] One method is adhesive bonding, which uses adhesive to firmly connect the lens to the housing. However, due to the aging properties of adhesives, the bonding strength decreases over long-term use. This is especially true in outdoor environments where police lights are frequently exposed to direct sunlight, high temperatures, rain, and temperature fluctuations, significantly accelerating the aging process and compromising long-term fixation strength, potentially leading to lens loosening or even detachment. Another method involves using a third structural component for clamping and fixing. This method combines the lens with the housing through an independent clamping component, addressing the adhesive aging issue to some extent. However, this method typically increases design and production costs, and the complex structure may negatively impact the installation and overall aesthetics of the police light. These limitations make existing police lights prone to structural instability during long-term use, reducing product lifespan and potentially affecting the reliability of their warning function. Utility Model Content

[0004] The purpose of this utility model is to provide an embedded warning light lens device to solve the problem that the fixing method of the lens and the housing affects the stability and durability of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an embedded warning light lens device, comprising:

[0006] A lens housing, on which a groove is provided;

[0007] The lens body is mounted on the lens shell;

[0008] A protrusion is provided on the lens body, and the protrusion passes through and is fixed in the groove.

[0009] Preferably, the groove portion includes a lens groove formed on the lens housing, and the lens groove has a through hole.

[0010] Preferably, the protrusion includes a plurality of columnar protrusions fixed to the back of the lens body.

[0011] Preferably, the outer surface of the columnar protrusion is provided with an anti-slip texture.

[0012] Preferably, the surface of the lens body is provided with an anti-glare coating or an anti-scratch coating.

[0013] An embedded warning light lens welding device is used for welding the embedded warning light lens device, comprising:

[0014] Soldering iron tip;

[0015] The groove is formed on the soldering iron tip.

[0016] Preferably, the groove is formed at the bottom end of the soldering iron tip.

[0017] Preferably, the groove is hemispherical.

[0018] Preferably, the groove of the soldering iron tip is provided with a high-temperature resistant coating.

[0019] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0020] This embedded siren lens device uses a protrusion on the lens body to pass through and be fixed to a groove on the lens shell. This avoids the problem of reduced fixing strength due to aging caused by adhesive bonding, thus improving long-term reliability. This device eliminates the reliance on adhesive and avoids fixing failure caused by outdoor environmental factors such as ultraviolet rays, rain, high temperature, and temperature difference changes. It ensures that the siren light maintains a stable structure in various environments. Compared with traditional screw or additional clamping structure fixing methods, the protrusion of this invention achieves rapid fixing through self-locking or welding, without the need for additional structural parts. This simplifies the assembly process and reduces production and maintenance costs. The soldering iron tip has a hemispherical groove that can accurately match the shape of the lens protrusion, ensuring stability during the welding process. Meanwhile, the groove is equipped with a high-temperature resistant coating, which can reduce the adhesion of impurities during welding, improve welding quality, and further enhance the reliability of fixation. The surface of the lens body is equipped with an anti-glare coating or an anti-scratch coating, which can effectively reduce light reflection, improve the light efficiency of warning lights, and enhance the wear resistance of the lens, extending its service life. The protrusion adopts a columnar protrusion structure, and its outer surface is equipped with anti-slip texture, which can provide better friction during assembly, so that it can remain stable and fixed in the vehicle vibration environment, not easily loosening, and improving safety.

[0027] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3 As shown, an embedded warning light lens device includes a lens housing 1 with a groove 2; a lens body 21 disposed on the lens housing 1; and a protrusion 3 disposed on the lens body 21, which passes through the groove 2 and is fixed therein. In this embodiment, the lens housing 1 supports and protects the entire lens assembly, and the groove 2 provides an installation channel so that the lens body 21 can be securely embedded therein. The lens body 21 performs optical transmission and diffusion functions, ensuring that the light from the warning light is evenly distributed and improving the warning effect. The protrusion 3 is designed on the lens body 21 and is fixed by passing through the groove 2, so that the lens body 21 can be firmly attached to the lens housing 1, avoiding loosening or displacement, thereby improving the overall reliability of the device. This embodiment, by providing the groove 2 on the lens housing 1 and forming the protrusion 3 on the lens body 21, allows the lens body 21 to be securely installed and avoids displacement, improving the stability and durability of the device. Furthermore, this structure simplifies the installation process, reduces the use of additional fasteners, makes assembly more convenient, and lowers production costs. Because the lens body 21 is connected via an embedded and fixed method, it remains stable during prolonged use, thereby improving the reliability and lifespan of the warning light device.

[0029] In another embodiment, the shape of the groove 2 can be adjusted according to actual needs, for example, it can adopt a rectangular, circular, or elliptical structure to accommodate different types of protrusions 3. Furthermore, the protrusions 3 can be fixed by means of snaps, threaded connections, or adhesives to adapt to different assembly requirements and environmental conditions. The lens housing 1 can be made of high-strength plastic, glass, or composite materials to meet the strength and light transmittance requirements of different application environments. Meanwhile, the lens body 21 can be selected with different surface treatments, such as anti-glare coatings or scratch-resistant coatings, depending on the actual application to further optimize optical performance and durability.

[0030] The recessed portion 2 includes a lens recess 6 formed on the lens housing 1, and a through hole 7 is provided on the lens recess 6. In this embodiment, the lens recess 6 serves as the embedding area of ​​the lens body 21, and its size and shape are precisely designed to ensure that the lens body 21 can be stably placed on the lens housing 1. The through hole 7 further enhances the fixing effect, allowing the protrusion 3 to pass through the through hole 7 for snap-fit ​​or threaded fixing, thereby improving the connection stability between the lens body 21 and the lens housing 1. This structure not only ensures that the lens body 21 will not easily fall off under external force, but also provides a guiding function during assembly, improving installation efficiency. In addition, the presence of the through hole 7 helps to reduce stress concentration between the lens body 21 and the lens housing 1, avoiding deformation or damage caused by thermal expansion and contraction. By adding a through hole 7 to the lens recess 6, this embodiment makes the fixing of the protrusion 3 more stable, effectively improving the durability and vibration resistance of the warning light lens device. Furthermore, this design simplifies the assembly process, allowing the lens body 21 to be quickly aligned and fixed, reducing production and maintenance costs. The through-hole 7 can also provide drainage or heat dissipation functions under certain circumstances, preventing moisture or heat from accumulating inside the lens, thereby improving the service life and optical performance of the warning light lens.

[0031] In another embodiment, the shape of the through-hole 7 can be optimized according to the specific installation method, for example, it can be circular, elliptical, or grooved to accommodate different types of protrusions 3. Furthermore, the number and distribution of the through-holes 7 can be adjusted according to the stress characteristics of the lens body 21 to ensure optimal fixation. For specific applications, the through-holes 7 can also be used with sealing rings or rubber gaskets to provide better waterproof and dustproof performance. In addition, the depth and shape of the lens groove 6 can be appropriately adjusted to accommodate lens bodies 21 of different thicknesses and materials, ensuring wider applicability.

[0032] The protrusion 3 includes multiple columnar protrusions 31 fixed to the back of the lens body 21. In this embodiment, the multiple columnar protrusions 31 are evenly distributed on the back of the lens body 21 and are fixed by passing through the groove 2 (specifically including the lens groove 6 and the through hole 7 on it) on the lens housing 1. The multi-point distribution design of the columnar protrusions 31 provides more stable support, so that the lens body 21 will not be displaced or loosened due to vibration or external force after installation. Compared with a single protrusion structure, the multi-point fixing method can better distribute the force and improve the impact resistance and durability of the entire warning light lens device. In addition, the shape and size of the columnar protrusions 31 can be optimized according to the thickness of the lens body 21 and the fixing method to adapt to different assembly requirements. This embodiment achieves a stable fixation of the lens body 21 by using multiple columnar protrusions 31, improving the vibration resistance and service life of the warning light lens device. In addition, since the columnar protrusions 31 provide multiple fixing points, the force on the lens body 21 is more even, reducing the risk of damage caused by local stress concentration. This structure can also optimize the assembly process to some extent, improving the accuracy and reliability of lens installation.

[0033] In another embodiment, the shape of the columnar protrusions 31 can be adjusted according to different fixing requirements, such as adopting a tapered, trapezoidal, or threaded structure to provide better fixing effect. Furthermore, the number and distribution of the columnar protrusions 31 can be optimized according to the size and shape of the lens body 21, for example, increasing or decreasing the number of columnar protrusions 31 to accommodate lens assemblies of different sizes. For specific applications, the columnar protrusions 31 can also be combined with snap-fit ​​or flexible structures to provide quick installation and removal, improving maintenance convenience and adaptability.

[0034] The outer surface of the columnar protrusion 31 is provided with an anti-slip texture. In this embodiment, the outer surface of the columnar protrusion 31 is provided with an anti-slip texture to increase its surface friction, thereby enhancing its stability during the fixing process. The anti-slip texture can be longitudinal grooves, grid-like engravings, or spiral textures, etc., and its function is to increase the biting force of the columnar protrusion 31 when it is installed into the groove portion 2 (including the lens groove 6 and the through hole 7) of the lens housing 1, reducing loosening caused by vibration or external force. At the same time, the anti-slip texture can also enhance the bonding force between the protrusion 3 and the adhesive or snap-fit ​​structure, further improving the fixing effect. In addition, in some application scenarios, the anti-slip texture can also reduce the resistance of sliding installation during assembly, making the lens assembly smoother when inserted and improving assembly efficiency. This embodiment improves the fixing stability of the lens body 21 by adding an anti-slip texture to the outer surface of the columnar protrusion 31, making it less prone to loosening or falling off during long-term use. In addition, this design can also improve the biting force between the columnar protrusion 31 and the lens housing 1, thereby optimizing the reliability and durability of the overall assembly. The application of anti-slip texture can also reduce slippage caused by errors during installation, enabling the lens body 21 to be positioned more accurately and improving product consistency.

[0035] In another implementation, the form of the anti-slip texture can be adjusted according to different fixing methods, such as using annular bumps, micro-particle coatings, or rubber coatings, to further enhance friction and fixing stability. Furthermore, the depth and spacing of the anti-slip texture can be optimized according to specific application requirements; for example, increasing the texture depth in applications requiring stronger fixing force, while reducing texture friction in applications requiring easy disassembly and reassembly. For specific environments, the surface of the columnar protrusions 31 can also undergo special treatment, such as adding a corrosion-resistant coating or an anti-oxidation coating, to adapt to the needs of outdoor or high-humidity environments.

[0036] The surface of the lens body 21 is provided with an anti-glare coating or an anti-scratch coating. In this embodiment, the anti-glare coating is used to reduce direct reflection of light and optimize the uniform diffusion of light, thereby improving the visibility of the warning light and preventing strong light from interfering with the observer. This coating can be formed by physical etching or chemical plating, such as using a nano-level anti-reflective coating, to reduce light loss and improve the warning effect. The anti-scratch coating enhances the surface abrasion resistance of the lens body 21, preventing scratches caused by external environmental factors (such as dust, sand, or wiping), thereby extending the service life of the lens. This coating typically uses high-hardness transparent polymers or nano-ceramic materials to provide effective surface protection while ensuring light transmittance. This embodiment effectively reduces light pollution and improves the visibility of the warning light by adding an anti-glare coating to the surface of the lens body 21, enabling it to maintain a clear and conspicuous warning effect in various environments. At the same time, the application of the anti-scratch coating enhances the durability of the lens body 21, reduces the decrease in transparency caused by daily wear and tear, and ensures that the optical performance of the warning light is not affected after long-term use. In addition, the application of these coatings can reduce maintenance needs, increase the overall service life of the device, and reduce replacement and maintenance costs.

[0037] like Figures 4-5 As shown, an embedded police light lens welding device is also provided for welding the embedded police light lens device, including: a soldering iron tip 4; and a groove 5 formed on the soldering iron tip 4. In this embodiment, the soldering iron tip 4 is used to provide local high temperature to achieve welding and fixing of the lens assembly. The groove 5 formed thereon can accurately match the columnar protrusions 31 on the lens body 21, so that the welding point can be stably contacted during the welding process, ensuring accurate welding position, while avoiding heat damage to the surrounding area. The depth and shape of the groove 5 can be optimized according to different types of protrusions 3 to improve the stability and consistency of welding. During the welding process, after the soldering iron tip 4 is heated to a predetermined temperature, the groove 5 can guide the protrusions 3 or related connecting structures to be correctly positioned, so that the welding material can be fully melted and evenly covered on the welding surface, thereby ensuring a strong connection effect. In addition, the presence of the groove 5 can reduce heat diffusion during the welding process, improve energy utilization, thereby improving welding efficiency and reducing processing time. This embodiment, by setting the groove 5 on the soldering iron tip 4, makes the welding process more precise, improves welding quality, and avoids welding misalignment or incomplete welding. Meanwhile, this design reduces the thermal impact on the lens housing 1 and the lens body 21, minimizing deformation or damage caused by high temperatures and improving the overall reliability of the product. Furthermore, the guiding function of the groove 5 simplifies the welding operation, improving production efficiency and reducing the difficulty of worker operation, thus facilitating mass production.

[0038] In another embodiment, the shape of the groove 5 can be adjusted according to different welding requirements, such as using a semi-circular, V-shaped, or rectangular groove to adapt to different welding structures. Furthermore, the soldering tip 4 can be made of a high thermal conductivity alloy or ceramic coating to improve the uniformity of welding temperature and reduce oxidation. For automated production environments, the soldering tip 4 can be combined with an automated welding robot or a temperature control system to ensure the stability and consistency of welding quality. In addition, in certain special applications, the soldering tip 4 can also be equipped with replaceable grooves 5 to accommodate warning light lens assemblies of different sizes and shapes, improving the versatility of the welding device.

[0039] A groove 5 is formed at the bottom end of the soldering iron tip 4. In this embodiment, the groove 5 is located at the bottom end of the soldering iron tip 4, allowing it to precisely align with the columnar protrusion 31 or other welding parts on the lens body 21 during the soldering process. Compared to groove designs on the side or other locations, the bottom groove 5 can more directly transfer heat to the welding area, improving welding efficiency while ensuring uniform heating of the welding point and reducing the risk of incomplete soldering, cold soldering, or weak welding. During soldering, after the soldering iron tip 4 heats to the set temperature, the groove 5 can firmly hold the part to be soldered, preventing it from sliding or shifting during heating. This design not only improves welding accuracy but also prevents misalignment or deformation of materials due to thermal expansion during high-temperature soldering. In addition, the structure of the groove 5 helps to concentrate heat energy, improve welding efficiency, and reduce the thermal impact on surrounding non-welding areas, avoiding damage to the lens shell 1 or lens body 21. This embodiment, by placing the groove 5 at the bottom end of the soldering iron tip 4, makes the soldering operation more precise and efficient. This design ensures uniform heating of the weld joints, improving weld quality while reducing the impact of heat diffusion on other components and preventing structural damage caused by high temperatures. Furthermore, the guiding effect of groove 5 enhances weld stability, making it easier for operators or automated equipment to complete the weld, improving production efficiency and reducing defect rates.

[0040] In another embodiment, the shape of the groove 5 can be optimized according to different welding requirements, such as using a semi-circular, rectangular, or V-shaped groove to accommodate different types of columnar protrusions 31 or welding parts. Furthermore, the bottom end of the soldering iron tip 4 can adopt a replaceable groove design to accommodate welding parts of different sizes and shapes, improving the versatility of the welding device. For automated welding equipment, a temperature sensor or thermostat module can also be added to the soldering iron tip 4 to ensure the stability of the welding temperature and further optimize the welding quality.

[0041] The groove 5 is hemispherical. In this embodiment, the groove 5 adopts a hemispherical design, which allows it to better enclose the columnar protrusion 31 or other parts to be welded, providing a more uniform heating area. Compared to flat or other shaped grooves, the hemispherical groove 5 can reduce the concentration of contact pressure, improve the stability of the welding process, and reduce the risk of material damage due to local overheating. During welding, after the soldering iron tip 4 is heated to the set temperature, the hemispherical groove 5 can ensure that the heat energy is evenly transferred to the columnar protrusion 31, allowing the solder to fully melt and flow, thereby achieving a more reliable welding effect. In addition, the hemispherical design can guide the solder to distribute evenly, avoiding solder joint defects such as cold solder joints or incomplete welds. This structure can also reduce the possibility of solder overflow during welding, improve the aesthetics of the weld, and optimize the weld strength.

[0042] This embodiment improves heat conduction efficiency during welding by designing the groove 5 as a hemispherical shape, resulting in a more uniform and stable weld. This design reduces heat loss during welding, ensures complete melting of the weld area, and improves weld strength and reliability. Furthermore, the hemispherical structure reduces welding defects caused by uneven weld contact surfaces, improves weld quality, and lowers the risk of weld failure due to localized stress concentration.

[0043] In another embodiment, the shape of the groove 5 can be optimized according to specific application requirements, such as using an ellipsoidal, V-shaped, or U-shaped groove to accommodate different types of welded parts. Furthermore, the size of the hemispherical groove can be adjusted to accommodate columnar protrusions 31 of different diameters, improving the versatility of the welding device. For special applications, a high-temperature resistant coating or ceramic plating can be added to the surface of the groove 5 to improve durability, reduce solder adhesion, and enhance welding efficiency and maintainability.

[0044] The groove 5 of the soldering iron tip 4 is coated with a high-temperature resistant coating. In this embodiment, the high-temperature resistant coating covers the inner surface of the groove 5, and its main function is to improve the heat resistance of the soldering iron tip 4 and reduce oxidation and material loss during high-temperature soldering. This coating is typically made of ceramic coating, boron nitride coating, or other high-temperature and corrosion-resistant materials to ensure that the groove 5 maintains good thermal conductivity and durability even after prolonged use. During soldering, the high-temperature resistant coating can effectively reduce the adhesion of soldering materials (such as solder or plastic), preventing solder from accumulating or remaining inside the groove 5 during the soldering process, thereby improving the stability and ease of operation of the soldering process. In addition, the high-temperature resistant coating can also optimize heat conduction, making the temperature distribution inside the groove 5 more uniform, ensuring that the soldering area is heated evenly, and reducing the risk of cold solder joints or poor solder joints. This embodiment improves the durability of the soldering iron tip 4 by adding a high-temperature resistant coating inside the groove 5, and reduces surface wear and oxidation problems caused by long-term high-temperature use. This coating can also reduce solder adhesion, making the soldering operation smoother, improving soldering efficiency, and reducing maintenance costs. In addition, the optimized heat conduction characteristics ensure uniform heating of the welded parts, improve weld quality, and enhance the strength and reliability of the weld.

[0045] In another implementation, the high-temperature resistant coating can utilize different types of materials, such as nano-ceramic coatings, Teflon coatings, or silicon carbide coatings, to adapt to varying welding environments and temperature requirements. Furthermore, the coating thickness and coverage can be adjusted according to specific applications; for example, an anti-oxidation layer can be added where additional corrosion resistance is required, or a reinforced ceramic composite coating can be used in scenarios demanding greater wear resistance. For automated welding equipment, a self-cleaning function can also be added to the coating surface to reduce welding residue, improve welding efficiency, and extend equipment lifespan.

[0046] The lens housing 1 has a through hole 7 in the lens groove; the lens body 21 and the lens housing 1 are assembled together to form a lens assembly, with the lens body 21 completely embedded in the lens housing 1, and the front of the lens body 21 overlapping with the front of the lens housing 1; the columnar protrusion 31 on the lens body 21 passes through the through hole of the groove of the lens body 21 in the lens housing 1; the soldering iron tip 4 is provided with a hemispherical groove 5; when the soldering iron is heated, the columnar protrusion 31 of the lens is pressed against the back of the lens assembly, so that the soldering iron tip 4 is in close contact with the back of the lens housing 1, and the hemispherical groove 5 of the soldering iron tip 4 and the back of the lens housing 1 form a hemispherical closed inner cavity; the columnar protrusion 31 of the lens melts and overflows the hemispherical inner cavity when heated, the soldering iron is removed, and the top of the columnar protrusion 31 of the lens becomes a hemispherical protrusion. After cooling, the lens is fixed together with the lens housing; because the size of the hemispherical protrusion is larger than the width of the through hole of the lens housing, the lens body 21 will not separate from the lens housing 1.
