Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage technology, and in particular to a portable energy storage power supply that is dustproof and waterproof. Background Technology
[0002] In today's fast-paced life, portable power storage devices have become indispensable for outdoor activities and emergency backups. Whether it's campers enjoying peaceful moments in the wild or ensuring basic electricity supply during sudden power outages, they play a crucial role.
[0003] However, to achieve fast and convenient charging, most portable power banks place the charging port directly on the surface of the device casing without additional protection. In outdoor environments, the impact of exposed charging ports is particularly significant. For example, in humid weather, moisture in the air can easily enter the portable power bank, potentially causing internal metal components to rust and corrode, thus affecting the conductivity and stability of charging. Prolonged exposure to a humid environment may even cause short circuits, damaging the entire power bank. In dusty environments, dust particles accumulate at the port, not only obstructing the normal insertion of the charging plug but also generating heat during charging due to excessive dust accumulation, affecting heat dissipation and reducing the power bank's lifespan.

[0037] Please refer to Figures 1 to 3This utility model provides a portable energy storage power supply that is dustproof and waterproof, including a mounting shell 1, a heat dissipation structure 5, multiple charging ports 6, a waterproof structure 3, and a storage cavity 111. The mounting shell 1 includes a top cover 11, a bottom plate 12, and side plates 13. The top cover 11, bottom plate 12, and side plates 13 form a cavity for housing energy storage components. The side plates 13 include two opposing first side plates 131 and two opposing second side plates 132. The heat dissipation structure 5 is disposed on the second side plates 132. The charging ports 6 include those disposed on the first side plates 131, second side plates 132, and third side plates 132. A DC interface 62 is located on one side panel 131, and an AC interface 61 for slowly supplying power to external devices is located on the second side panel 132. The AC interface 61 is connected to a first sealing plate 2 for sealing the AC interface 61. The second side panel 132 also has a positioning groove 1321, and the first sealing plate 2 can be fastened to the positioning groove 1321. A waterproof structure 3 is located on another second side panel 132, below the heat dissipation structure 5, and is used to drain water from the receiving cavity 10. A storage cavity 111 is located on the top cover 11 for storing the charging cable.
[0038] In this embodiment, the top cover 11, the bottom plate 12, and the side plate 13 form a cavity, providing a stable installation space for the energy storage components. This design not only provides physical protection for the energy storage components, reducing the risk of damage due to collisions and friction during daily use and transportation, but also reduces the overall size of the product and improves portability through a compact layout.
[0039] In some embodiments, the mounting housing 1 can be made of engineering plastic. Engineering plastics possess excellent strength, protecting the mounting housing 1 from easy damage. Furthermore, engineering plastics also exhibit excellent corrosion resistance. Of course, the above is merely an example; the specific material can be determined according to actual needs, and this invention does not impose any limitations.
[0040] When the portable energy storage power supply 100 is in operation, the internal energy storage components and other electronic components generate heat. The heat dissipation structure 5 transfers the internal heat to the external environment via cool air. Specifically, heat is transferred from the heat-generating element to the housing cavity, the heat dissipation structure 5 guides external cool air into the housing cavity to remove the heat, and then dissipates it through the heat dissipation structure 5 on the second side plate 132, so as to maintain the component temperature within the housing cavity within a reasonable range and prevent performance degradation or safety issues due to overheating.
[0041] The DC interface 62 and AC interface 61 are used to connect different types of external devices or charging power supplies, respectively. When an external charging power supply is connected, current enters the energy storage component through the corresponding interface to charge the portable energy storage power supply 100. When an external electrical device is connected, the electrical energy in the energy storage component is output to the external device through the charging interface 6 to power it. Specifically, multiple AC interfaces 61 are provided on one of the second side panels 132 to meet the user's need to simultaneously provide slow power to multiple external devices. The slow power supply mode supported by the AC interface 61 can avoid damage to external devices due to excessive charging power, and can also reduce energy consumption and improve power efficiency to a certain extent. It is suitable for devices that do not require high charging speed but need stable power supply for a long time, such as small routers and emergency lighting equipment.
[0042] Please continue to refer to this. Figure 2 and Figure 3 The second side panel 132 is equipped with a first sealing plate 2 and a positioning groove 1321. The first sealing plate 2 can be fastened to the positioning groove 1321 to cover the AC interface 61. When the AC interface 61 is not in use, the sealing plate can prevent dust, moisture and other impurities from entering the interface, avoiding poor contact or short circuit problems caused by the accumulation of impurities, extending the service life of the interface, and ensuring the safety and reliability of the power supply. When the AC interface 61 needs to be used, the user can easily open the first sealing plate 2, making operation convenient.
[0043] After prolonged operation, the portable energy storage power supply 100 generates heat from the battery cells and other electronic components within its housing, causing the internal temperature to rise. If the external ambient temperature is low, especially in humid conditions, the hot air encountering the cool mounting casing 1 can easily lead to condensation, resulting in water droplets. For example, on summer nights, when the portable energy storage power supply 100 is used indoors, a rapid drop in nighttime temperature can cause water droplets to form inside the housing. This can not only corrode the internal electronic components but also threaten the safety of the portable energy storage power supply 100 due to short circuits, significantly impacting its performance and lifespan.
[0044] Please refer to Figure 8 and Figure 9 To address the aforementioned issues, the second side panel 132 is also equipped with a waterproof structure 3, which is located below the heat dissipation structure 5. By providing the waterproof structure 3 below the heat dissipation structure 5, not only can the water droplets generated by condensation inside the cavity be discharged outside the mounting housing 1, but the water droplets can also be prevented from affecting the heat dissipation structure 5, thus enabling the portable energy storage power supply 100 to simultaneously possess high protective performance in terms of waterproofing and dustproofing.
[0045] In addition, the storage cavity 111 of the top cover 11 of the portable power storage 100 is designed to facilitate the storage of the charging cable. When the user is not using the portable power storage 100, the charging cable can be stored to prevent it from falling out at will, making it easy to organize and carry. At the same time, it also reduces the possibility of the charging cable being damaged due to tangling or pulling, thus improving the user experience.
[0046] The mounting housing 1 of this utility model is provided with a first sealing plate 2 and a waterproof structure 3. When the AC interface 61 is not in use, the first sealing plate 2 can cover and seal multiple AC interfaces 61 to prevent moisture, dust and other foreign objects from accumulating at the AC interfaces 61 and affecting the safety and stability of charging. The waterproof structure 3 can drain condensation droplets inside the receiving cavity 10 to the outside of the receiving cavity 10, protecting the internal components from damage and improving the safety, stability and service life of the portable energy storage power supply 100.
[0047] Please refer to Figure 8 and Figure 9 In some embodiments, the waterproof structure 3 includes a plurality of through holes 31 arranged in an array, the inner wall of the through holes 31 extending toward the receiving cavity, the inner wall being set at an angle to the inner wall of the second side plate 132, and forming an opening 32 toward the upper cover 11.
[0048] When condensation droplets form on the inner wall of the second side plate 132, due to gravity, the liquid droplets will fall along the inner wall into the opening 32, and then slide along the inner wall of the inclined through hole 31 to the outside of the mounting housing 1. This prevents them from falling into the receiving cavity and thus avoiding any impact on the battery cell and other components. Compared to traditional planar waterproof designs, this structure with an inclined inner wall and a specific orientation of the through hole 31 greatly improves the waterproof effect, effectively reducing problems such as short circuits and corrosion caused by moisture ingress, and ensuring the safe operation of the portable energy storage power supply 100.
[0049] In some embodiments, the first sealing plate 2 is movably connected to the second side plate 132.
[0050] There are several possible connection methods between the first sealing plate 2 and the second side plate 132, such as sliding connection and rotational connection. For example, the first sealing plate 2 can be rotatably connected to the second side plate 132. When the AC interface 61 needs to be used, the first sealing plate 2 can be manually rotated to open it and expose the AC interface 61. When the AC interface 61 is not needed, the first sealing plate 2 can be manually rotated to engage with the positioning groove 1321, locking the interface and protecting the AC interface 61 from moisture and dust.
[0051] In some embodiments, the second side plate 132 is provided with a groove 1322, and the first sealing plate 2 is movably connected to the groove 1322.
[0052] Please refer to Figure 3This can be understood as follows: the second side plate 132 forms a groove 1322, and the first sealing plate 2 is rotatably connected to the groove 1322. Constrained by the groove 1322, the sealing plate can only rotate based on the groove 1322, achieving precise opening and closing. At the same time, the groove 1322 provides a support structure for the first sealing plate 2, ensuring that even if the first sealing plate 2 is in a frequently opening and closing state, it will not wobble or shift, effectively maintaining the stability of the overall structure.
[0053] Please refer to Figure 5 In some embodiments, the first sealing plate 2 abuts against one side of the groove 1322 and is provided with positioning blocks 21 at both ends. The groove 1322 is provided with positioning holes 1323 at both ends. The positioning blocks 21 can be rotatably connected to the positioning holes 1323 to drive the first sealing plate 2 to rotate relative to the AC interface 61.
[0054] In other words, the positioning block 21 rotatably connects to the positioning hole 1323, providing a precise pivot point for the rotation of the first sealing plate 2, thus achieving stable rotation of the first sealing plate 2 around the AC interface 61. This connection method between the positioning block 21 and the positioning hole 1323 reduces the use of additional connecting parts, simplifies the overall structure, and lowers production costs.
[0055] Furthermore, the positioning block 21 and the positioning hole 1323 are distributed at both ends of the groove 1322 and the first sealing plate 2. This layout not only ensures the balance of the first sealing plate 2 when it rotates, but also makes full use of the space around the AC interface 61. Within the limited space of the second side plate 132, the AC interface 61 is protected without wasting space due to an overly complex structural design.
[0056] The rotating connection between the positioning block 21 and the positioning hole 1323 makes the opening and closing operation of the first sealing plate 2 smoother. Users can easily open and close the AC interface 61 by simply rotating the first sealing plate 2, making the operation intuitive and simple. At the same time, this design ensures more uniform resistance during the opening and closing process of the first sealing plate 2, avoiding jamming caused by uneven force and greatly improving the user experience.
[0057] Please continue to refer to this. Figure 5 In some embodiments, a latching element 22 is provided on the side of the first sealing plate 2 facing the second side plate 132, and the latching element 22 is fastened to the positioning groove 1321. When the first sealing plate 2 covers the AC interface 61, the latching element 22 can be fastened to the positioning groove 1321, firmly fixing the first sealing plate 2 and preventing it from shaking. This fastening design and the rotation positioning structure are independent of each other but work together to further improve the overall structure of the first sealing plate 2. In addition, it further enhances the stability of the first sealing plate 2, enabling it to more effectively block dust, moisture and other foreign objects, reducing the risk of failure caused by interface contamination.
[0058] In some embodiments, the surface of the first sealing plate 2 facing away from the buckle 22 is provided with a pressing part 23, and the pressing part 23 is provided with a plurality of protrusions 231.
[0059] Please refer to Figure 4 A pressing part 23 is provided on the side of the first sealing plate 2 facing away from the buckle 22. This design conforms to ergonomic principles, so when the user needs to open the first sealing plate 2 that is fastened to the positioning groove 1321, the point of force applied by the hand is naturally concentrated on the pressing part 23. Multiple protrusions 231 are distributed on the surface of the pressing part 23, increasing the friction between the hand and the pressing part 23, ensuring that the hand will not easily slip during the application of force. In addition, the protrusions 231 serve a positioning function, allowing the user to easily identify the position of the pressing part 23.
[0060] In some embodiments, a plurality of protruding structures 231 are provided in a dotted manner on the surface of the pressing portion 23. Of course, the above is only an example, and the specific shape can be determined according to actual needs. This utility model is not limited herein.
[0061] In some embodiments, the upper cover 11 is recessed toward the receiving cavity to form a receiving cavity 111, and the receiving cavity 111 is connected to the first sealing plate 2.
[0062] Please refer to Figure 2 The top cover 11 is recessed towards the receiving cavity to create a storage cavity 111. This utilizes the internal space of the top cover 11 and provides users with additional storage area without increasing the overall size of the product. The storage cavity 111 can be used to store small accessories such as charging cables and adapters, making it convenient for users to quickly access them when using the energy storage power supply.
[0063] The storage cavity 111 is connected to the first sealing plate 2, which effectively covers the storage cavity 111, preventing items inside from falling out and providing good protection. In addition, it can also effectively prevent dust, moisture and other impurities from entering, avoiding damage to the accessories inside the storage cavity 111 due to contamination.
[0064] Please continue to refer to this. Figure 2 and Figure 6 In some embodiments, a first side plate 131 is provided with a plurality of DC interfaces 62, wherein two DC interfaces 62 are connected to a second sealing plate 4. The second sealing plate 4 includes a sealing plate body 41, a connecting part 42 connected to the sealing plate body 41, and an operating part 43 disposed opposite to the connecting part 42. The sealing plate body 41 covers the DC interfaces 62, and the connecting part 42 is connected to the first side plate 131.
[0065] Multiple DC interfaces 62 are located on the first side panel 131, meeting the user's needs for DC power supply equipment and enriching the application scenarios of the portable energy storage power supply 100. This layout, together with the AC interface 61 on the second side panel 132 and the storage cavity 111 on the top cover 11, meets the diverse usage needs of users from multiple dimensions.
[0066] The sealing plate body 41 directly covers the DC interface 62, providing physical protection to prevent dust, moisture, and other impurities from entering the interface and avoiding poor contact or short circuits caused by impurity accumulation. The connecting part 42 connects to the first side plate 131, providing support for the sealing plate body 41. Thanks to the connecting part 42, the sealing plate body 41 will not fall off when not in use. The operating part 43 is positioned opposite the connecting part 42, facilitating user application of force. When the user needs to open or close the second sealing plate 4, simply applying appropriate force to the operating part 43 will move the sealing plate body 41, conforming to ergonomic design principles.
[0067] Please refer to Figure 2 , Figure 6 as well as Figure 7 In some embodiments, the first sealing plate 2 is rectangular, one second sealing plate 4 is circular, and the other second sealing plate 4 is rectangular. Of course, the above are only examples, and the specific shape can be determined according to actual needs. This utility model does not limit the specific shape.
[0068] Please refer to Figure 1 In some embodiments, the first side panel 131 is further provided with an information display screen 7 for display. The display screen 7 is connected to the control circuit inside the portable energy storage power supply 100 to obtain various status information of the portable energy storage power supply 100, such as battery level, charging current, output voltage, etc. The control circuit converts these electrical signals into digital signals or image signals and displays them on the display screen 7 in an intuitive manner, so that the user can understand the working status of the portable energy storage power supply 100 in real time and improve the user experience.
[0069] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
