Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile power supply technology, and more specifically to a high-temperature resistant and explosion-proof mobile power supply. Background Technology
[0002] A portable power bank, also known as a "power bank," is a portable charger that integrates power supply and charging functions. It is primarily used to provide power to various electronic devices, such as mobile phones, tablets, and laptops, in situations where an external power source is unavailable, solving their battery life issues. The main structural components of a current portable power bank include: a casing: serving to protect internal components, commonly made of plastic, primarily ABS / PC, or metal, such as aerospace-grade aluminum, which enhances the product's texture and durability; a circuit board: mainly comprising a boost system, charging system, and protection board. The boost and charging systems handle the input and output of electrical energy, boosting the energy stored in the battery cells to a suitable voltage for charging digital devices; the protection board is the lithium battery's charging management IC, fully controlling the slow charging, constant current charging, and constant voltage charging modes of the lithium battery, preventing overcharging, over-discharging, and output short circuits, protecting the battery and extending its lifespan; and the battery cells: the core component of the portable power bank, performing the task of "storing" electrical energy, using internal chemical substances to store and release energy. Commonly used battery cells include the 18650 lithium battery, a common lithium battery cell, with a diameter of 18mm, a height of 65mm, and a capacity typically between 2000-3000mAh; there are also advanced lithium polymer cells, which have advantages such as large capacity, low internal resistance, and customizable shape.
[0003] For example, the power bank disclosed in the prior art (CN222852042U) includes a suspension component and a charging power bank body. The charging power bank body is provided with a suspension part, a cable outlet part, and a retractable cable module. The retractable cable module includes a data cable and a data cable connector. The cable outlet part is located close to the suspension part. When the charging power bank body is in a suspended state, the data cable connector is tilted relative to the suspension direction and positioned on the cable outlet part. By positioning the cable outlet part close to the suspension part and tilting the data cable connector relative to the suspension direction for storage, the swing amplitude caused by the data cable exiting can be reduced, making it easier for the user to apply force and thus allowing for easier one-handed pulling out of the data cable, further improving the user experience.
[0004] However, the existing technology described above still has the following problems in use: When traditional power banks are placed in use, their bottoms are in contact with the surface, preventing air circulation. They can only rely on the power bank itself for heat dissipation, which is inefficient and can lead to excessively high temperatures of internal components. This not only affects charging power but can also cause the power bank to explode, resulting in insufficient safety. Therefore, this invention provides a high-temperature resistant and explosion-proof power bank. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a high-temperature resistant and explosion-proof power bank. Through the charging port, fast charging cable, and magnetic charging unit on the main body of the power bank, charging is flexible, convenient, and fast. Multiple support plates can stably support the power bank, facilitating airflow at the bottom and improving heat dissipation. This prevents the power bank from overheating, which could affect charging power and safety, thereby enhancing its explosion-proof performance and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and explosion-proof power bank, comprising a power bank body, a charging port and multiple equally spaced indicator lights fixedly embedded on the top of the power bank body, a fast charging cable connected to one side of the charging port, two lithium-ion battery cells installed inside the power bank body, a high-temperature resistant film between the two lithium-ion battery cells, a magnetic charging unit at the front end of the power bank body, and multiple evenly distributed slots at the rear end of the power bank body, each slot having a support plate hinged inside, and each support plate having a threaded fastening bolt, the support plate being fixed to the power bank body by the fastening bolt.
[0007] In a preferred embodiment, the inner wall of the magnetic charging unit is fixed with multiple evenly distributed magnetic blocks. The multiple magnetic blocks cover the entire area, resulting in a large magnetic attraction area and making it difficult for the magnetic blocks to fall off. Mobile phones that support wireless charging or can be paired with magnetic phone cases can also achieve stable magnetic charging and be used to charge devices.
[0008] In a preferred embodiment, the top of the power bank body has a slot, and the connector of the fast charging cable is inserted into the slot. When not in use, the connector of the fast charging cable is placed in the slot, which can prevent the fast charging cable from shaking and affecting its carrying and use.
[0009] In a preferred embodiment, each support plate has a storage hole at its rear end, and the fastening bolt is located inside the storage hole. This arrangement prevents the fastening bolt from protruding outwards and affecting the aesthetics.
[0010] In a preferred embodiment, a rubber pad is adhered to the rear end of each support plate. The surface of the rubber pad is processed with anti-slip texture. The rubber pad is soft, and the anti-slip texture on its surface can increase friction, which can further improve the stability of the power bank body.
[0011] In a preferred embodiment, a rectangular groove is provided on one side of the power bank body, and a control switch is fixedly installed inside the rectangular groove to facilitate the control of the power bank body charging.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model can charge three devices simultaneously through the charging port, fast charging cable and magnetic charging unit on the main body of the power bank. The charging is flexible, convenient and fast. Multiple support plates can be used to stably support the power bank, which facilitates air circulation at the bottom of the power bank. This can improve the heat dissipation of the power bank, avoid the power bank temperature from being too high, and avoid affecting the charging power and safety, thereby improving the explosion-proof performance.
[0014] 2. The power bank features four indicator lights that clearly display the remaining battery level. It also includes a control switch to easily disconnect the power supply, enhancing charging safety. The power bank is compact with rounded edges, making it easy to slip into a pocket and carry.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a high-temperature resistant and explosion-proof portable power bank, including a portable power bank body 1. The top of the portable power bank body 1 is fixedly embedded with a charging port 2 and multiple equally spaced indicator lights 3. A fast charging cable 4 is connected to one side of the charging port 2. Two lithium-ion battery cells 5 are installed inside the portable power bank body 1, and a high-temperature resistant film 6 is provided between the two lithium-ion battery cells 5. A magnetic charging unit 7 is provided at the front end of the portable power bank body 1. A rectangular groove 15 is opened on one side of the portable power bank body 1, and a control switch 16 is fixedly installed inside the rectangular groove 15 to facilitate the control of the charging of the portable power bank body 1.
[0023] In actual use, the power bank body 1 can charge three devices simultaneously via the charging port 2, fast charging cable 4, and magnetic charging unit 7. It also supports simultaneous charging and discharging, meaning that while charging itself, it can charge two other devices via a wired and magnetic wireless connection. Charging is flexible, convenient, and fast. Furthermore, the design of four indicator lights 3 makes it easy to intuitively and clearly display the remaining power of the power bank body 1. In addition, a control switch 16 is set in the rectangular groove 15 on the side wall of the power bank body 1, which makes it easy to disconnect the power supply of the power bank body 1 at any time, thereby improving charging safety. The entire power bank is small and rounded, and can be easily put into a pocket, making it very convenient to carry.
[0024] In this embodiment, both the charging port 2 and the fast charging cable 4 support 33W wired charging, while the magnetic charging unit 7 can output up to 7.5W. At the same time, both the fast charging cable 4 and the charging port 2 support up to 30W self-charging, providing rapid power replenishment.
[0025] like Figure 2 and Figure 3 As shown, multiple evenly distributed slots 8 are provided at the rear end of the power bank body 1. Each slot 8 is hinged with a support plate 9. Each support plate 9 is threaded with a fastening bolt 10. The support plate 9 is fixed to the power bank body 1 by the fastening bolt 10. Each support plate 9 has a storage hole 13 at its rear end. The fastening bolt 10 is located inside the storage hole 13.
[0026] When a user charges this power bank, multiple support plates 9 can be flipped open sequentially from multiple slots 8 and fixed to the main body 1 of the power bank using fastening bolts 10. Then, the power bank is laid flat, and the multiple support plates 9 stably support the power bank, creating a gap for air circulation at the bottom of the power bank. This can improve the heat dissipation of the power bank to a certain extent, prevent the power bank temperature from getting too high, which would affect the charging power and safety, and thus improve the explosion-proof performance.
[0027] Furthermore, a rubber pad 14 is attached to the rear end of each support plate 9. The surface of the rubber pad 14 is processed with anti-slip texture. The rubber pad 14 is soft in texture, and the anti-slip texture on its surface can increase friction, which can further improve the stability of the mobile power bank body 1.
[0028] Refer to the instruction manual appendix Figure 4 The inner wall of the magnetic charging unit 7 is fixed with multiple evenly distributed magnetic blocks 11. The magnetic blocks 11 have a magnetic attraction force of 13N, which is comprehensive, has a large magnetic attraction area, and is not easy to fall off. Mobile phones that support wireless charging or can be paired with magnetic phone cases can also achieve stable magnetic charging and be used to attract devices for charging.
[0029] The power bank body 1 has a slot 12 on its top. The connector of the fast charging cable 4 is inserted into the slot 12. When not in use, the connector of the fast charging cable 4 is placed in the slot 12 to prevent the fast charging cable 4 from shaking and affecting its carrying and use.
[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
