Description

Technical Field

[0001] This utility model relates to the field of electronic device charging interface protection technology, and in particular to a novel waterproof and dustproof charging interface structure. Background Technology

[0002] In the existing technology, many electronic devices do not have protective measures for their charging interfaces. Especially when using electronic devices outdoors, the lack of dustproof and waterproof protection for the charging interfaces can easily lead to water entering the internal electronic components of the electronic devices, thereby affecting the lifespan of the electronic devices.

[0003] As a widely used lighting tool, the application scenarios of flashlights have expanded from traditional home backup to various fields such as outdoor adventure, military and police duty, industrial inspection, and emergency rescue. These complex and harsh usage environments are often accompanied by humidity, rain, splashes, and even brief immersion. The charging interfaces in the current technology do not have any localized waterproofing treatment. The core functional module of the flashlight—the circuit board (PCBA)—is covered with various electronic components and metal solder joints. External aging, wear, or accidental damage can easily allow liquids to directly contact the circuit board through the interface or gaps, leading to component corrosion, short circuits, or battery failure, causing permanent damage to the flashlight and posing a serious safety hazard.

[0004] Therefore, there is an urgent need to design a more reliable and independent waterproof protection structure for the flashlight circuit board itself, which can effectively prevent the intrusion of water vapor and liquid even if the outer casing seal fails, ensuring the safe and stable operation of the core circuit and improving the overall reliability and service life of the product. Utility Model Content

[0005] The purpose of this utility model is to provide a novel waterproof and dustproof charging interface structure to solve the technical problem that water can enter the internal circuit board structure due to the lack of dustproof and waterproof protection measures in the charging interface of electronic devices in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel waterproof and dustproof charging interface structure, including an interface shell, a circuit board inserted into the interface shell, and a locking piece threadedly connected and fixed to the interface shell. The interface shell is provided with a charging interface groove, and the charging interface groove is provided with a through hole corresponding to the position of the charging interface on the circuit board. A sealing component and a pressure plate are placed in the charging interface groove to seal the charging interface for waterproof and dustproof purposes.

[0007] Preferably, the charging interface groove is provided with a sealing component step and a pressing plate step. The sealing component step is used to limit and engage the sealing component, and the pressing plate step is used to limit and engage the pressing plate.

[0008] Preferably, the pressure plate is provided with a countersunk platform, and the sealing assembly includes an upper layer and a lower layer. The upper layer is provided with a boss, and the lower layer and the countersunk platform are each provided with a charging interface through hole. The boss and the charging interface through hole are the same size and can be plugged into each other.

[0009] Preferably, the through hole of the charging interface corresponds to the position of the through hole in the charging interface groove, and is used to insert a charging cable. The size of the through hole in the charging interface groove is larger than the size of the through hole of the charging interface.

[0010] Preferably, the tablet is placed between the upper and lower layers.

[0011] Preferably, the sealing assembly is made of silicone.

[0012] Preferably, the locking plate, interface housing, and pressure plate are made of aluminum alloy.

[0013] Preferably, the charging interface is a Type-C interface.

[0014] Preferably, the interface housing is further provided with a groove through hole corresponding to the size of the power button position on the circuit board.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a novel waterproof and dustproof charging interface structure, which comprehensively solves the sealing problem of charging interfaces in electronic products through multiple sealing, coordinated limiting, and user-friendly design. Its advantages are mainly reflected in the following aspects: 1. High-level waterproof and dustproof: Using waterproof and dustproof silicone as the core sealing component, it achieves complete wrapping and airtight sealing around the charging interface, which can effectively prevent moisture, water vapor, dust and other contaminants from entering the device, significantly improving the reliability and service life of the product in humid, dusty and other harsh environments.

[0016] 2. Multiple seals for high reliability: The design does not rely on a single sealing point. The first layer of waterproofing is achieved by pressing the charging interface groove with silicone, and the second layer of waterproofing and dustproofing is achieved by pressing the aluminum alloy sheet with silicone layer. This multi-seal structure greatly reduces the risk of failure and makes the protection more reliable.

[0017] 3. Simplified structure and efficient assembly: The entire structure consists of three core components: interface shell, silicone, and pressing sheet. This reduces the complexity of the mold and the difficulty of production assembly, making it easy for the assembly line to press and assemble quickly, which helps to improve production efficiency and control costs.

[0018] 4. Limiting and fixing design: The design of the boss and the step provides precise installation limit for the silicone parts of the sealing component, preventing them from rotating or shifting during use. This ensures the precise fixing of the tablet itself and the durability of the seal, while also preventing the edges of the tablet from scratching the product's appearance, thus balancing functionality and aesthetics.

[0019] 5. User-friendly experience: The recessed design is a crucial optimization for user experience. It provides guidance and tolerance for the insertion of the charging connector, effectively preventing connection issues caused by a short connector or slight deviations in the user's insertion angle, resulting in smoother plugging and unplugging and a better experience.

[0020] 6. Easy to manufacture: The aluminum alloy sheet and silicone used are very mature, cost-controllable and easy to mass-produce materials and processes, which are very suitable for the manufacturing needs of consumer electronics products.

[0021] 7. Enhance product competitiveness: This application design can give products high protection levels such as IP67 / IP68 at a lower cost, greatly enhancing the product's market competitiveness in outdoor sports, industrial applications, and daily splash protection scenarios, and meeting consumers' higher requirements for the durability of electronic products.
