Description

Technical Field

[0001] This utility model relates to the field of battery heat dissipation and insulation technology, and in particular to a high-efficiency outdoor light for rugged mobile phones and a battery heat dissipation and insulation structure. Background Technology

[0002] In extreme outdoor environments, rugged phones need to provide stable power support for high-power outdoor LED lights. Key parameters include a wide voltage input range of 1.8-3.4V (to adapt to the dynamic adjustment needs of LED drivers under different operating conditions), a peak instantaneous current of 2660 mA (to ensure luminous efficacy output in high-brightness mode), and a luminous flux of 1274 LM (meeting the high-intensity lighting standards for outdoor scenarios). However, when LED light assemblies are under high load for extended periods, the battery cells generate Joule heating due to the large current flow, causing local temperatures to rise sharply to 60-80℃, far exceeding the operating threshold of conventional electronic components.

[0003] In existing technologies, the heat energy of the battery cell and surrounding circuits cannot be dissipated quickly, forming a heat retention area. This causes the battery electrolyte to evaporate more rapidly, resulting in capacity decay (reducing cycle life by 30%-50%). High-temperature environments may trigger the decomposition of the SEI film inside the battery cell, releasing active materials and exacerbating the exothermic reaction, ultimately leading to thermal runaway and threatening equipment safety. Traditional heat dissipation solutions, such as single-layer graphite sheets or metal heat-conducting sheets, can only achieve a lateral heat conduction efficiency of 6-8 W / m·K, which is difficult to cope with instantaneous high heat flux density (>100 W / cm²) scenarios, resulting in low overall thermal management efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-efficiency outdoor light and battery heat dissipation and insulation structure for rugged mobile phones.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rugged mobile phone high-efficiency outdoor light and battery heat dissipation and insulation structure, including a mobile phone shell, a battery body fixed to the inner wall of the mobile phone shell, an LED light body fixed to the surface of the mobile phone shell, a light connector on the surface of the LED light body, a heat insulation foam on one side of the battery body, a secondary graphite sheet on one side of the heat insulation foam, and a primary graphite sheet on one side of the secondary graphite sheet.

[0006] Preferably, a substrate frame is provided on one side of the primary graphite sheet, and a honeycomb heat insulation frame is fixed to the inner wall of the substrate frame. The inner wall of the honeycomb heat insulation frame is filled with aerogel heat insulation material. In the prior art, thermal radiation heat can cause heat to accumulate in certain parts, resulting in uneven thermal stress, affecting the stability of materials and structures, and may even cause deformation, damage, and other problems, affecting their performance and lifespan. To address this problem, this utility model solves it by installing a honeycomb heat insulation frame, realizing the design of a honeycomb-shaped metal frame between the LED component and the battery, with aerogel heat insulation material inside. The honeycomb structure enhances mechanical strength, and the aerogel blocks heat radiation, resulting in lightweight, high heat insulation, and improved impact resistance, meeting the requirements for three-proof (waterproof, dustproof, and shockproof) and achieving the effect of improving the service life of the equipment.

[0007] Preferably, a track side plate is fixed to the inner wall of the mobile phone casing, and a trapezoidal groove is formed on the inner wall of the track side plate. A trapezoidal track component is slidably connected to the inner wall of the trapezoidal groove. Trapezoidal track components are fixed to both ends of the base frame, both ends of the primary graphite sheet, both ends of the secondary graphite sheet, and both ends of the heat insulation foam. In the prior art, in some specific industries, users have personalized requirements for the heat insulation and heat dissipation of the equipment. However, the existing heat dissipation structure is often fixed, making it difficult for users to choose different components to combine according to their needs. This makes it difficult to meet the personalized needs of users and reduces the competitiveness of the product. With the continuous development of technology, the requirements for heat insulation and heat dissipation will continue to increase. When it is necessary to improve the heat insulation or heat dissipation performance, the entire system needs to be redesigned and modified, which is costly and time-consuming. To address this problem, this utility model adopts the method of installing a track side plate, which realizes the design of heat dissipation components, graphite sheets, heat insulation layers, etc. as pluggable modules. Users can replace heat dissipation modules of different specifications according to environmental needs, such as a waterproof coating version for high humidity environments. This makes the equipment easy to maintain and upgrade, adapts to diverse usage scenarios, and improves the applicability of the equipment.

[0008] Preferably, a spring sheet is fixed to one side of the trapezoidal track component, and an embedded ball is fixed to one end of the spring sheet. The inner wall of the trapezoidal slide is provided with an embedded ball groove, which realizes the temporary fixation of the component through the matching of the embedded ball groove and the embedded ball, preventing slippage during use and achieving the effect of improving the stability of the equipment.

[0009] Preferably, the top of the heat insulation foam is provided with a wiring groove, which facilitates the wiring of the lamp connector and reduces the space occupied by the component.

[0010] Preferably, a base plate is fixed to the bottom of the track side plate, and a rectangular groove is provided on the top of the base plate, which facilitates the positioning and stopping of the heat insulation and heat dissipation components, thereby improving the user experience.

[0011] Preferably, the top and bottom of the ladder track component are covered with a rubber layer, which reduces component wear and improves the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, the heat energy of the battery cell and surrounding circuits cannot be dissipated quickly, forming heat retention areas. This causes the battery electrolyte to evaporate more rapidly, leading to capacity decay. High-temperature environments may trigger the decomposition of the SEI film inside the battery cell, releasing active materials and exacerbating exothermic reactions, ultimately leading to thermal runaway and threatening device safety. Traditional heat dissipation solutions, such as single-layer graphite sheets or metal heat-conducting sheets, can only achieve a lateral heat conduction efficiency of 6-8 W / m·K, which is insufficient to cope with instantaneous high heat flux density scenarios, resulting in low overall thermal management efficiency. To address this problem, this utility model solves it by installing graphite sheets. In the structural design of rugged phones, the LED light body and battery components are vertically stacked to optimize the spatial layout. A multi-level heat dissipation and insulation system is integrated between the two, including a dual-level graphite sheet heat dissipation module and a heat insulation foam barrier layer. The first-level graphite sheet is closely attached to the LED light substrate and is installed using graphite material with high thermal conductivity. The material utilizes a dual-path heat dissipation mechanism, where the high instantaneous heat flux generated by the LED chip is rapidly transferred via lateral thermal diffusion, and the secondary graphite sheet adheres to the surface of the battery module. Simultaneously, the heat transferred from the primary graphite sheet is evenly distributed to the heat dissipation area of ​​the entire casing via longitudinal thermal conduction, forming a lateral diffusion and longitudinal conduction heat dissipation mechanism that improves overall heat dissipation efficiency by 40%-50%. Furthermore, nano-ceramic composite foam is embedded between the two graphite sheets, utilizing its low thermal conductivity to block the radiative heat transfer path from the LED module to the battery, ensuring that the battery surface temperature rise is controlled at ≤8℃. The foam layer also provides elastic cushioning, protecting the structural integrity of the graphite sheet in impact and vibration scenarios, meeting the compact requirements of ruggedized equipment. The synergistic effect of multi-stage heat dissipation and active insulation keeps the battery area temperature stable below 45℃ during continuous LED operation. The high-temperature resistance and moisture-proof properties of the graphite sheet and foam are suitable for long-term stable operation in extreme outdoor environments, thus improving the applicability of the equipment.

[0014] 2. In the prior art, thermal radiation heat can cause heat to accumulate in certain parts, resulting in uneven thermal stress, affecting the stability of materials and structures, and may even cause deformation, damage and other problems, affecting their performance and lifespan. To address this problem, this utility model adopts the method of installing a honeycomb heat insulation frame (401), which realizes the design of a honeycomb metal frame between the LED component and the battery, and fills the inside with aerogel heat insulation material (402). The honeycomb structure enhances mechanical strength, aerogel blocks heat radiation, is lightweight and has high heat insulation, and at the same time improves impact resistance, meets the requirements of three protections, and achieves the effect of improving the service life of the equipment.

[0015] 3. In the existing technology, in some specific industries, users have personalized requirements for the heat insulation and heat dissipation of equipment. However, the existing heat dissipation structure is often fixed, and it is difficult for users to choose different components to combine according to their own needs. This makes it difficult to meet the personalized needs of users and reduces the competitiveness of the product. With the continuous development of technology, the requirements for heat insulation and heat dissipation will continue to increase. When it is necessary to improve the heat insulation or heat dissipation performance, the entire system needs to be redesigned and modified, which is costly and time-consuming. In response to this problem, this utility model adopts the method of installing track side plate (3) to solve the problem. It realizes that the heat dissipation components, graphite sheets, heat insulation layers, etc. are designed as plug-in modules. Users can replace the heat dissipation modules of different specifications according to environmental needs, such as the waterproof coating version for high humidity environment, which makes the equipment easy to maintain and upgrade, adapt to diverse usage scenarios, and achieve the effect of improving the applicability of the equipment.

In some specific industries, users have personalized requirements for the heat insulation and heat dissipation of the equipment. However, the existing heat dissipation structure is often fixed, making it difficult for users to choose different components to combine according to their own needs. This makes it difficult to meet the personalized needs of users and reduces the competitiveness of the product. With the continuous development of technology, the requirements for heat insulation and heat dissipation will continue to increase. When it is necessary to improve the heat insulation or heat dissipation performance, the entire system needs to be redesigned and modified, which is costly and time-consuming. The installation of the track side plate 3 solves this problem. It realizes that the heat dissipation components, graphite sheets, heat insulation layers, etc. are designed as pluggable modules.

[0029] The working principle of this utility model is as follows: In the structural design of rugged mobile phones, the LED light body 102 and the battery assembly are assembled in a vertical stacking manner to optimize the spatial layout. A multi-level heat dissipation and insulation system is integrated between the two, including a two-stage graphite sheet heat dissipation module and a heat insulation foam barrier layer. The first-stage graphite sheet 2 is closely attached to the LED light substrate and uses graphite material with a high thermal conductivity (≥1500W / m·K) to quickly transfer the instantaneous high heat flux density (peak value 120W / cm²) generated by the LED chip through lateral heat diffusion. The second-stage graphite sheet 201 is attached to the surface of the battery assembly and distributes the heat transferred by the first-stage graphite sheet 2 evenly to the heat dissipation area of ​​the entire casing through longitudinal heat conduction, forming a dual-path heat dissipation mechanism of lateral diffusion and longitudinal conduction, which improves the overall heat dissipation efficiency by 40%-50%. Meanwhile, nano-ceramic composite foam 202 (thermal conductivity ≤0.03W / m·K) is embedded between the two-stage graphite sheets. Its low thermal conductivity blocks the radiative heat transfer path from the LED component to the battery, ensuring that the battery surface temperature rise is controlled at ≤8℃ (compared to the solution without a heat insulation layer). The foam layer also has an elastic buffer function (compression rate 15%-20%), protecting the structural integrity of the graphite sheets in impact and vibration scenarios, meeting the compact requirements of tri-proof equipment. At the same time, the multi-stage heat dissipation and active heat insulation work together to keep the battery area temperature stable below 45℃ when the LED is working continuously (national standard GB31241-2014 safety threshold). The high temperature resistance (-40℃~150℃) and moisture resistance (IP68 rating) of the graphite sheets and foam are suitable for long-term stable operation in extreme outdoor environments.
