TECHNICAL FIELD
[0001] The utility model relates to electronic equipment technical field especially, it relates to three proofings mobile phone with flashlight waterproof structure lighting function. BACKGROUND
[0002] In recent years, with the improvement of people's living standards and the pursuit of healthy lifestyle, outdoor adventure, camping, hiking and other sports are becoming more and more popular. In these activities, participants often face complex and changeable natural environment, such as walking at night, bad weather, etc., so there is an urgent need for mobile phones with powerful lighting function and waterproof performance.
[0003] In the prior art, during outdoor adventure, camping, hiking and other activities, it may encounter rain, humidity and other environments. Flashlights without waterproof function lack reliability in outdoor adventure, camping, hiking and other activities, and cannot meet the lighting needs of users in complex environments, such as heavy rain or flood, so the flashlight cannot be used normally, which will affect the rescue and rescue action. Special professional workers such as divers, underwater photographers, firefighters and construction workers need waterproof mobile phone flashlights for lighting or signal indication when working underwater or in humid environment. In daily life, the mobile phone may come into contact with water, such as accidentally getting wet when washing hands. Waterproof mobile phone flashlight can avoid failure or damage caused by water ingress, prolong the service life, and waterproof mobile phone flashlight can better meet the high requirements of users on product performance and quality, thereby improving the competitiveness of the product in the market. UTILITY MODEL CONTENT
[0004] The utility model aims at solving the shortcomings in the prior art and provides a three-proof mobile phone with flashlight waterproof structure lighting function.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the three-proof mobile phone with flashlight waterproof structure lighting function, including mobile phone shell, the surface of mobile phone shell is fixed with display screen assembly, the back of mobile phone shell is equipped with mobile phone lamp slot, the inner wall of mobile phone lamp slot is fixed with back shell lens, the surface of back shell lens is equipped with recess, the inside of recess is fixed with light transmission lens, the bottom of back shell lens is fixed with lamp shade, the bottom of back shell lens is fixed with waterproof foam, the inside of mobile phone shell is fixed with rack, the upper end of rack is fixed with lamp head module, the inside of lamp head module is fixed with lamp wick, the surface of mobile phone lamp slot is fixedly connected with the bottom of waterproof foam.
[0006] Preferably, an aluminum plate is fixed to the back of the frame, and the back of the aluminum plate is snapped to the bottom of the lampshade. In the prior art, the LEDs generate a lot of heat when working, mainly because electrical energy is converted into light and heat energy. Furthermore, the luminous efficiency of the LEDs is not 100%, and some electrical energy is released as heat. In addition, the PN junction of the LEDs also generates heat after being energized. If this heat is not dissipated in time, it will cause the LED temperature to become too high, thus affecting its performance and lifespan. Excessive temperature accelerates the light decay of LED chips, leading to decreased brightness. Prolonged high temperatures can cause the packaging material to age, resulting in yellowing, cracking, and other problems, affecting light output efficiency and protection performance. High temperatures also accelerate the corrosion of pins and brackets, leading to poor contact and open circuits. To address these issues, this invention uses aluminum plate material. The principle of heat dissipation in aluminum components is mainly based on the high thermal conductivity of aluminum and the ability to achieve efficient heat dissipation by increasing the heat dissipation area through design. As a good thermal conductor, aluminum can quickly conduct heat from the heat source to other parts of the aluminum component, thereby improving heat dissipation efficiency. Heat is transferred from the surface of the aluminum component to the surrounding environment through convection and radiation, accelerating heat dissipation and thus improving the heat dissipation efficiency of the mobile phone flashlight, preventing heat accumulation that could damage the bulb.
[0007] Preferably, the upper end of the frame is threaded with a bolt, and the frame is slidably connected to a second aluminum plate via the bolt. A sealing sleeve is fixed to the upper end of the second aluminum plate, and a pressure-relieving plate is slidably connected inside the second aluminum plate. The upper end of the bolt is threaded with a nut, and the pressure-relieving plate is equipped with a buffer plate inside. The pressure-relieving plate and the buffer plate have good elasticity and can provide a certain elastic compensation when the bolt is tightened, absorb part of the tightening force, prevent rigid contact between the bolt and the nut, and thus reduce the extrusion deformation of the parts.
[0008] Preferably, a rubber sleeve is fixed to the periphery of the mobile phone casing. The rubber material has good elasticity and toughness, which can effectively absorb and buffer the impact force when the mobile phone is bumped or dropped, reducing the risk of damage to the internal components of the mobile phone.
[0009] Preferably, the back of the phone casing is fixed with a back cover, and the surface of the back cover is provided with anti-slip texture. The anti-slip texture can increase the friction between the fingers and the back of the phone casing, making the phone more stable in the hand and less likely to slip.
[0010] Preferably, the light-transmitting lens material is high-alumina silicon glass, which has extremely high hardness and impact resistance and is not easily broken.
[0011] Beneficial effects:
[0012] 1. In existing technologies, outdoor adventures, camping, hiking, and other activities may encounter rainy or humid environments. Flashlights lacking waterproof features are unreliable in these activities and cannot meet users' lighting needs in complex environments, such as heavy rain or floods. In such cases, the flashlight may malfunction, affecting distress calls and rescue operations. Specialized professionals such as divers, underwater photographers, firefighters, and construction workers require waterproof flashlights for illumination or signaling when working underwater or in humid environments. In daily life, mobile phones may come into contact with water, such as when washing hands, and waterproof flashlights may become unusable. Waterproof flashlights can prevent malfunctions or damage caused by water ingress, extending their lifespan. Waterproof mobile phone flashlights better meet users' high demands for product performance and quality, thereby enhancing the product's competitiveness in the market. To address this issue, this invention employs a novel waterproof lighting structure. When a worker turns on the mobile phone flashlight underwater, the carefully arranged waterproof foam sealing layer around the lampshade acts as a robust barrier, effectively preventing water from seeping in from any gaps. Secondly, the lens is tightly sealed, further enhancing the overall waterproof capability and ensuring the interior remains dry even in deep water. These two lines of defense work together to provide reliable waterproof protection for the flashlight. Simultaneously, the use of ABS shell material for the lamp slot not only improves its strength and durability but also better focuses the light, making it more concentrated and bright. Furthermore, the lens's excellent light transmission ensures efficient light transmission, enabling the flashlight to achieve a bright illumination effect underwater. This design not only improves the flashlight's waterproof performance but also enhances its underwater lighting effect, providing a more reliable and brighter lighting tool for underwater operations.
[0013] 2. In existing technologies, LED chips generate a significant amount of heat during operation, primarily due to the conversion of electrical energy into light and heat energy. Furthermore, the luminous efficiency of LED chips is not 100%, with some electrical energy released as heat. Additionally, the PN junction of the LED chip also generates heat when energized. If this heat is not dissipated promptly, it can lead to excessively high LED chip temperatures, affecting performance and lifespan. Excessive temperature accelerates light decay in the LED chip, resulting in decreased brightness. Prolonged high temperatures can cause aging of the packaging material, leading to yellowing, cracking, and other problems, affecting light output efficiency and protective performance. High temperatures also accelerate corrosion of the pins and brackets, causing poor contact and open circuits. To address these issues, this invention utilizes aluminum plate material. The heat dissipation principle of aluminum components is based on aluminum's high thermal conductivity and the ability to increase the heat dissipation area through design to achieve efficient heat dissipation. As a good thermal conductor, aluminum can quickly conduct heat from the heat source to other parts of the aluminum component, thereby improving heat dissipation efficiency. Heat is transferred from the surface of the aluminum component to the surrounding environment through convection and radiation, accelerating heat dissipation and improving the heat dissipation efficiency of the mobile phone flashlight, preventing heat accumulation that could damage the bulb.

The surface of the phone light slot 202 is fixedly connected to the bottom of the waterproof foam 204. In existing technology, during outdoor adventures, camping, hiking, and other activities, users may encounter rainy or humid environments. Flashlights lacking waterproof functionality are unreliable in these activities and cannot meet the lighting needs of users in complex environments, such as heavy rain or floods. A malfunctioning flashlight can hinder distress and rescue operations. Specialized professionals such as divers, underwater photographers, firefighters, and construction workers require waterproof mobile phone flashlights for illumination or signaling when working underwater or in humid environments. In daily life, mobile phones may come into contact with water, such as when washing hands. Waterproof mobile phone flashlights prevent malfunctions or damage caused by water ingress, extending their lifespan. Waterproof mobile phone flashlights also better meet users' high demands for product performance and quality, thereby enhancing the product's competitiveness in the market. To address this issue, this invention employs a novel waterproof lighting structure. When a worker turns on the flashlight underwater, the carefully arranged waterproof foam 204 adhesive sealing layer around the lampshade 203 acts as a robust barrier, effectively preventing water from seeping in from any gaps. Secondly, the lens is tightly sealed, further enhancing the overall waterproof capability and ensuring the interior remains dry even in deep water. These two lines of defense work together to provide reliable waterproof protection for the flashlight. Meanwhile, the ABS shell used to create the lamp housing not only improves its strength and durability but also better focuses the light, making it more concentrated and bright. Simultaneously, the lens's excellent light transmission ensures efficient light transmission, enabling the flashlight to achieve a bright illumination effect underwater. This design not only improves the flashlight's waterproof performance but also enhances its underwater illumination, providing a more reliable and brighter lighting tool for underwater operations.

A sealing sleeve 301 is fixed to the upper end of the second aluminum plate 3. A pressure-relieving piece 304 is slidably connected inside the second aluminum plate 3. A nut 303 is threaded to the upper end of the bolt 302. A buffer piece 305 is provided inside the pressure-relieving piece 304. A rubber sleeve 4 is fixed to the periphery of the mobile phone shell 1. A back cover 5 is fixed to the back of the mobile phone shell 1. The surface of the back cover 5 is provided with anti-slip texture 501. The light-transmitting lens 201 is made of high-alumina silicon.
[0025] The working principle of this invention is as follows: When a worker turns on the flashlight underwater, the first layer of waterproof foam 204 adhesive sealing around the lampshade 203 acts as a sturdy barrier, effectively preventing water from seeping in from any gaps. Secondly, the lens is tightly sealed, further enhancing the overall waterproof capability and ensuring the interior remains dry even in deep water. These two lines of defense work together to provide reliable waterproof protection for the flashlight. Simultaneously, the use of ABS shell material for the lamp slot not only improves its strength and durability but also better focuses the light, making it more concentrated and bright. Furthermore, the lens's excellent light transmission ensures efficient light transmission, enabling the flashlight to achieve a bright illumination effect underwater. This design not only improves the flashlight's waterproof performance but also enhances its underwater illumination, providing more reliable and brighter lighting for underwater operations.
