[0021] As attached Figure 1 To be continued Figure 5 As shown: This embodiment provides an explosion-proof lithium battery structure for digital products, including a protective shell 1. Several first springs 2 are fixedly connected to both sides of the inner cavity of the protective shell 1. One end of the several first springs 2 is fixedly connected to a first buffer plate 3. A rubber shock-absorbing pad 4 is fixedly connected to one side of the first buffer plate 3. A second buffer plate 5 is fixedly connected to one side of the rubber shock-absorbing pad 4. A protective inner shell 6 is fixedly connected to one side of the second buffer plate 5. Heat sinks 7 are fixedly connected to the top and bottom of the protective inner shell 6. A condenser tube 8 is connected through the inner cavity of the heat sink 7. Three sets of battery fixing blocks 9 are fixedly connected to the inner cavity of the protective inner shell 6. Several grooves are opened on the inner wall of each set of battery fixing blocks 9. A second spring 10 is fixedly connected to the inner cavity of the several grooves. A connecting rod 11 is fixedly connected to the other end of the second spring 10. A battery placement sleeve 12 is fixedly connected to the other end of the several connecting rods 11. A battery 13 is movably connected to the inner wall of the battery placement sleeve 12.
[0022] Specifically, the bottom of the protective shell 1 is fixedly connected to a fixed base plate 14, and threaded holes are opened at the four corners of the top of the fixed base plate 14. A baffle 16 is threadedly connected to the inner cavity of the threaded hole.
[0023] In this embodiment, by using the fixed base plate 14 and the baffle 16 together, the device can be firmly installed in the cavity of the digital product, ensuring that the device will not loosen during long-term use and improving the tightness between the device and the cavity of the digital product.
[0024] Specifically, the inner walls of several battery holders 12 are provided with anti-slip textures.
[0025] In this embodiment, the anti-slip texture effectively increases the friction between the battery 13 and the contact surface, ensuring that the battery 13 is firmly fixed during use and will not slide or fall off the installation position due to vibration, external force or long-term use, thereby improving the stability and reliability of the device.
[0026] Specifically, the protective shell 1, the first buffer plate 3, the rubber shock-absorbing pad 4, and the second buffer plate 5 are all equipped with heat dissipation vents.
[0027] In this embodiment, the heat dissipation performance of the battery 13 can be improved by setting up heat dissipation vents, preventing overheating, thereby ensuring the normal operation of the battery 13 and extending its service life.
[0028] Specifically, sliding grooves are provided on the top and bottom of one side of the protective shell 1, and baffles 16 are slidably connected to the inner cavity of the two sliding grooves.
[0029] In this embodiment, the sliding groove and the baffle 16 work together to effectively block the internal structure of the device, prevent the internal structure of the device from falling off during use, and improve the stability of the internal structure of the device.
[0030] The working principle and usage process of this utility model: The user fixes the device to the inside of the digital product using bolts 15. When the user needs to replace the battery 13, the baffle 16 is pulled out to one side, and the battery 13 is placed into the inner wall of the battery holder 12, with the positive terminal of the battery 13 facing the battery control circuit board inside the digital product. The baffle 16 serves to block the internal structure of the device, preventing slippage and detachment, and also prevents external dust from entering the device. After the battery 13 is placed into the inner wall of the battery holder 12, the surface of the battery holder 12 is fixedly connected to the connecting rod 11, and the connecting rod 11 is fixedly connected to the second spring 10. Under the elastic action of the second spring 10, the battery holder 12 presses against the battery 13, which can firmly clamp batteries 13 of different specifications, ensuring that the battery 13 will not loosen under normal working conditions. At the same time, it provides necessary adjustment and relief when the battery 13 expands slightly during use, avoiding internal damage caused by excessive expansion. Heat sinks 7 are fixedly connected to the top and bottom of the protective inner shell 6. A condenser tube 8 is connected through the inner cavity of the heat sink 7. The heat sink 7 and the condenser tube 8 can dissipate heat from the battery 13, enabling the battery 13 to achieve efficient heat dissipation during daily operation and reducing the possibility of battery explosion. First springs 2 are fixedly connected to both sides of the inner cavity of the protective outer shell 1. A first buffer plate 3 is fixedly connected to the other end of the first spring 2. One side of the first buffer plate 3 is fixedly connected to a rubber shock-absorbing pad 4. The rubber shock-absorbing pad 4 is fixedly connected to a second buffer plate 5. With the cooperation of the first spring 2, the first buffer plate 3, the rubber shock-absorbing pad 4 and the second buffer plate 5, when the digital product encounters an external impact, the first spring 2 can play a buffering role, quickly absorbing the external impact force and reducing the impact force on the internal structure, thereby reducing the risk of damage. The first buffer plate 3, the rubber shock-absorbing pad 4 and the second buffer plate 5 can play a pressure-resistant and shock-absorbing role for the device, enabling the digital product to maintain structural integrity when encountering an impact and improving the service life of the device.
[0031] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
