Description

Technical Field

[0001] This application relates to the field of outdoor power supply equipment, and in particular to an outdoor waterproof portable power supply. Background Technology

[0002] As a portable energy storage device, outdoor power banks have gradually become an important tool in camping, travel, and emergency power supply scenarios in recent years, driven by the popularization of outdoor activities and technological advancements. Their portability and multifunctionality provide great convenience to users and have also promoted the rapid development of related industries. However, in complex and ever-changing outdoor environments, the waterproof performance of power banks becomes a crucial factor affecting their reliability and safety, especially in extreme conditions such as rain or wading, where the quality of waterproof performance directly impacts the normal use of the device. Currently, most outdoor power banks on the market achieve basic waterproofing through simple shell sealing designs. For example, waterproof strips, silicone plugs, or sealing caps are used to protect the power interface to prevent water droplets from entering the device. In addition, some products also have basic splash-proof structures at the charging port, such as rubber sleeves or simple water-blocking sheets, to block external moisture. While these methods improve the device's waterproofing to some extent, they are only suitable for minor splashes and cannot meet the needs of use in harsh environments such as heavy rain or prolonged wading. Furthermore, existing technologies still have significant shortcomings in waterproofing measures at the connection between the power plug and the charging plug. When a charging plug with water droplets is inserted into a power plug, water can easily seep into the power supply through the gap between the plug and the charger, causing a short circuit or damage to the circuit, thus affecting the normal operation of the device. Therefore, how to effectively prevent water from seeping in from the connection between the charging plug and the power plug has become an urgent technical problem to be solved. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide an outdoor waterproof portable power bank.

[0004] An outdoor waterproof portable power bank includes a housing with a hinged lid on top. Multiple power plugs and a charging cable are located inside the housing. One end of the charging cable is a charging plug, and the other end is a waterproof connector. The charging plug is used to connect to the power connector and provide current to the charging cable. A water-blocking ring is provided at the end of the charging plug. By adopting this technical solution, when the user inserts the charging plug into the power plug, the water-blocking ring at the end of the charging plug scrapes off water from the charging plug, preventing water from entering the power plug and effectively preventing water seepage from the connection between the charging plug and the power plug, thus preventing power plug malfunction. Preferably, the charging plug is provided with electrode posts, and the electrode posts are covered with a rubber waterproof pad. A retaining ring is provided on the inner wall of the power plug, which is used to push the rubber waterproof pad to slide out of the electrode posts. By adopting the above technical solution, when the user inserts the charging plug into the power plug, the retaining ring pushes the rubber protective pad outward, thereby exposing the electrode posts on the charging plug, facilitating power connection between the electrode posts and the power connector. The rubber waterproof pad prevents water from entering the electrode posts, reducing malfunctions during charging. Preferably, a baffle is fixedly connected to the outside of the rubber waterproof pad, which cooperates with the retaining ring. By adopting the above technical solution, when the user uses the device, the retaining ring applies reverse pressure to the push plate, pushing the push plate outward from the power connector, thereby separating the rubber waterproof pad from the electrode posts. Preferably, a spring is provided on the side of the baffle away from the retaining ring, with one end of the spring fixedly connected to the baffle and the other end fixedly connected to the charging plug. By adopting the above technical solution, when the user uses the device, the retaining ring pushes the baffle towards the charging plug, the baffle compresses the spring, and when the charging plug separates from the power connector, the tension of the spring causes the baffle and the rubber waterproof pad to return to their original positions. The rubber waterproof pad covers the electrode posts, isolating them from the outside environment and reducing water contact with the electrode posts. Preferably, the inner wall of the retaining ring is provided with anti-slip texture. By adopting the above technical solution, the anti-slip texture increases the friction between the retaining ring and the rubber waterproof pad during use, thus facilitating the retaining ring to slide the rubber waterproof pad outwards. Preferably, a waterproof plug is inserted into the power plug. By adopting the above technical solution, when not in use, the waterproof plug blocks the power plug, preventing water and water vapor from entering the power plug. Preferably, one side of the housing is hinged to the housing body, and the other side is connected to the housing body via a snap-fit ​​connection. By adopting the above technical solution, the snap-fit ​​connection facilitates easy opening and closing of the power supply unit during use. Preferably, a handle is hinged to the top of the power supply unit. By adopting the above technical solution, the handle facilitates the movement of the power supply unit during use.

[0010] The following will be combined with the appendix Figure 1-4 This application provides a clear and complete description of the technical solutions in the embodiments of this utility model. The described embodiments are merely possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can, in conjunction with the embodiments of this utility model, obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this utility model. This application provides an outdoor waterproof portable power bank, referring to... Figure 1 and Figure 2 The device includes a housing 1, with a lid 11 hinged to the top of the housing 1. Multiple power plugs 14 are installed inside the housing 1, along with a charging cable 2. One end of the charging cable 2 is a charging plug 21, and the other end is a waterproof connector 22. The charging plug 21 is used to connect to the power connector and provide current to the charging cable 2. A water-blocking ring 141 is provided at the end of each power plug 14. One side of the housing 1 is hinged to the housing 1, and the other side is connected to the housing 1 via a snap-fit ​​13. A handle 12 is hinged to the top of the lid 11 for easy carrying and use.

[0011] Specifically, the enclosure 1 is made of high-strength aluminum alloy, which has good impact resistance and corrosion resistance. The cover 11 is connected to the enclosure 1 by a stainless steel hinge, ensuring structural stability. Multiple power plugs 14 are installed inside the enclosure 1. Each power plug 14 has a silicone water-blocking ring 141 at its end, which effectively removes water droplets from the charging plug 21 and prevents water from entering the power plug 14.

[0012] In addition, refer to Figure 3 and Figure 4The power plug 14 is fitted with a waterproof plug 15. When not charging, the waterproof plug 15 prevents external water and water vapor from entering the power plug 14, further enhancing its waterproof performance. The end of the charging plug 21 has an electrode post 211, which is covered by a rubber waterproof pad 212. A plastic baffle 213 is fixedly connected to the rubber waterproof pad 212. A spring 214 is located on the side of the baffle 213 away from the power plug 14, with one end fixedly connected to the baffle 213 and the other end fixedly connected to the charging plug 21. A retaining ring 142 is provided on the inner wall of the power plug 14. When the charging plug 21 is inserted into the power plug 14, the retaining ring 142 pushes the rubber waterproof pad 212 outwards, thus exposing the electrode post 211 for easy power connection. Simultaneously, the inner wall of the retaining ring 142 has anti-slip textures, increasing the friction between the retaining ring 142 and the rubber waterproof pad 212, facilitating the outward sliding of the rubber waterproof pad 212.

[0013] Specifically, the electrode post 211 is made of copper alloy, possessing excellent conductivity and corrosion resistance. The rubber waterproof gasket 212 is made of natural rubber, offering good elasticity and sealing performance. The baffle 213 is made of polypropylene, lightweight and corrosion-resistant. The spring 214 is made of stainless steel, exhibiting good elasticity and corrosion resistance. The retaining ring 142 is made of stainless steel with an anodized surface treatment, enhancing its wear resistance and corrosion resistance.

[0014] When the charging plug 21 is separated from the power plug 14, the tension of the spring 214 causes the baffle 213 and the rubber waterproof pad 212 to return to their original positions. The rubber waterproof pad 212 covers the electrode post 211, isolating the electrode post 211 from the outside environment and reducing the possibility of water contacting the electrode post 211. This design not only improves waterproof performance but also extends the service life of the device.

[0015] The implementation principle of this embodiment is as follows: by setting a water-blocking ring 141 at the end of the power plug 14 and a rubber waterproof pad 212 on the charging plug 21, water can be effectively prevented from seeping in from the connection between the charging plug 21 and the power plug 14, avoiding short circuits or damage, and improving the reliability and safety of the equipment. At the same time, by using a high-strength aluminum alloy housing 1 and stainless steel hinges and other parts, the impact resistance and corrosion resistance of the equipment are enhanced, adapting to the needs of use in various complex environments. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
