[0054] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0055] It should be noted that, unless otherwise stated, the technical or scientific terms used in this disclosure should have the meaning that would be understood by one of ordinary skill in the art to which this disclosure pertains.

[0056] With the development of technology, the amount of data on computers is increasing and becoming more important, making data protection particularly crucial, especially data being processed, which can easily be lost in the event of power outages or other abnormal situations.

[0057] To address the aforementioned technical problems, this disclosure provides a power failure protection device and an electronic device that can save data in the event of a power failure.

[0058] Example 1

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a power failure protection device includes a data management card 1 and a power supply module 2. The first side of the data management card 1 is detachably connected to a first electronic device 3, and the power supply module 2 is disposed on the second side of the data management card 1. One end of the power supply module 2 is provided with a snap-fit ​​structure 223, which is used to snap-fit ​​with the crossbeam 34 of the first electronic device 3. The second side is the side opposite to the first side. When the first electronic device 3 is powered off, the power supply module 2 supplies power to the data management card 1 so that the data management card 1 can save the data of the electronic device.

[0060] Data Management Card 1 is a hardware device for data storage. During normal operation, it manages and optimizes data read / write operations, and in the event of a power failure, quickly saves cached data to non-volatile storage. It integrates a controller, memory, non-volatile memory (such as flash memory or solid-state drives), and necessary interface circuitry. The controller manages and schedules all data operations. For example, it can execute complex algorithms to optimize data layout, improve read / write efficiency, and implement mechanisms such as wear leveling and garbage collection to extend the lifespan of the storage media. Memory is directly connected to the controller via a high-speed bus, ensuring fast data transfer and low-latency access. Memory stores data being processed or data about to be written to non-volatile memory, ensuring rapid read and write operations during processing. Memory provides the controller with temporary workspace for executing complex algorithms and data processing tasks. Non-volatile memory can be connected to the controller via a storage interface to receive and execute data read / write commands. When the power-off protection mechanism is activated, the non-volatile memory receives cached data from memory and safely saves it, preventing data loss. The interface circuit is responsible for communicating with the host system, supports multiple interface standards, and ensures that the data management card 1 can be flexibly connected to different host platforms.

[0061] Specifically, Data Management Card 1 can be a RAID (Redundant Array of Independent Disks) controller card. A RAID controller card is a key component for implementing disk array functionality, combining multiple physical hard drives into one or more logical drives to provide data redundancy, performance enhancement, and fault tolerance. Data Management Card 1 can also be an SSD controller (Solid State Drive Controller), a core component built into the solid state drive, responsible for managing data read and write operations on the flash memory chips, including wear leveling, garbage collection, and error correction. Data Management Card 1 can also be a smart storage card, a storage controller integrating advanced algorithms and intelligent management functions, capable of optimizing data layout, improving read and write efficiency, and enhancing data protection. Data Management Card 1 can also be a database management card, a hardware accelerator specifically designed for database systems to improve the speed and efficiency of database queries. It can significantly improve database performance by accelerating operations such as index creation, sorting, and aggregation.

[0062] The first and second sides of the data management card 1 can be the outer periphery of the data management card 1, such as the two long sides or two wide sides of the rectangular data management card 1. Connecting the long or wide sides of the data management card 1 to the motherboard 31 of the first electronic device 3 saves space on the plane of the motherboard 31, allowing more devices to be installed on the motherboard 31. Specifically, the data management card 1 can also be connected to the periphery of the power supply module, i.e., the long or wide side of the power supply module, thus avoiding occupying more projection space on the motherboard and further allowing more devices to be installed on the motherboard 31.

[0063] Power supply module 2 is a module that provides power support to electronic devices, especially in the event of a mains power outage, enabling it to immediately take over power supply tasks and ensure the system continues to operate long enough to complete critical operations, such as data saving. Specifically, power supply module 2 can be an uninterruptible power supply (UPS), seamlessly switching to its built-in battery 212 during mains power interruptions to provide continuous power to connected devices until power is restored or the devices are safely shut down. Power supply module 2 can also be a supercapacitor module, using supercapacitors as energy storage elements. Compared to traditional batteries 212, supercapacitors offer faster charging and discharging speeds, longer cycle life, and better temperature adaptability, making them suitable for applications requiring rapid response and short-term power support. Power supply module 2 can also be a battery 212, such as a lithium battery 212 module, using lithium-ion or lithium polymer batteries 212. These power supply modules 2 have high energy density, small size, and light weight, making them suitable for portable devices or space-constrained applications. Power supply module 2 can also be a hybrid power supply module 2, combining two or more types of energy storage technologies, such as a combination of supercapacitors and lithium batteries 212, designed to leverage the advantages of each to improve overall performance and reliability.

[0064] The first electronic device 3 refers to a host system or main control device directly connected to the data management card 1. Specifically, the first electronic device 3 can be a server, i.e., a high-performance computer specifically designed to provide services and resources on a network. As the first electronic device 3, the server expands its storage capacity and performance through the data management card 1, especially in application scenarios requiring high availability and large-scale data processing. The first electronic device 3 can also be a personal computer, referring to general-purpose computing devices designed for individual users, including desktops, laptops, and tablets. They are widely used in areas such as office work, entertainment, learning, and personal creation. Their storage performance and reliability can be improved through the data management card 1. The first electronic device 3 can also be an industrial control computer, a rugged computer specifically designed for industrial automation and manufacturing environments, capable of stable operation under harsh working conditions. They have higher protection levels and wider operating temperature ranges, suitable for use in factories, mines, oil drilling platforms, and other locations. Industrial control computers can achieve real-time monitoring and control of the production process through the data management card 1, ensuring the security and continuity of critical data. The first electronic device 3 can also be a mobile device, referring to portable electronic devices such as smartphones, tablets, and portable media players. They are widely used in areas such as personal communication, entertainment, office work, and social networking. Mobile devices can also serve as the first electronic device 3, with their storage capacity expanded via an external data management card 1.

[0065] The snap-fit ​​structure 223 is a mechanical connection device used to securely fasten two or more components together. By tightly engaging with the crossbeam 34 of the first electronic device 3, the snap-fit ​​structure 223 ensures that the power supply module 2 will not easily loosen or fall off after installation. It is particularly suitable for applications with high vibration or harsh environments. Specifically, the snap-fit ​​structure 223 can be a push-pull type; the user simply aligns the power supply module 2 with the crossbeam 34 and gently pushes it in to complete the installation. The snap-fit ​​structure 223 can also be a spring-loaded type; the snap-fit ​​structure 223 has a built-in spring that automatically pops out and locks when the power supply module 2 is inserted into the crossbeam 34, ensuring the module will not loosen. For disassembly, the user simply presses the spring clip to easily remove the module. The snap-fit ​​structure 223 can also be a screw-fixed type; the snap-fit ​​structure 223 is fixed to the crossbeam 34 with screws, providing a stronger mechanical connection. This more stable connection is suitable for applications requiring long-term use and not requiring frequent replacement. The snap-fit ​​structure 223 can also be a slide rail snap-fit ​​structure 223, in which the power supply module 2 is connected to the crossbeam 34 via a slide rail, allowing the user to push the module in or pull it out along the slide rail. The slide rail can have a locking mechanism to ensure that the module does not loosen after installation. The snap-fit ​​structure 223 can also be a quick-release snap-fit ​​structure 223, designed with a quick-release button or lever, allowing the user to quickly unlock and remove the power supply module 2 simply by pressing a button or pulling a lever.

[0066] The crossbeam 34 is an internal or external support structure of the first electronic device 3, used to install and fix various components, such as power modules, storage devices, expansion cards, and graphics cards. The crossbeam 34 can be made of metal or plastic, possessing a certain strength and rigidity to withstand a certain weight and external force. Specifically, the crossbeam 34 can be a guide rail or bracket inside the chassis 32, used to support and fix components such as power modules and hard drives.

[0067] This disclosure, by setting up a data management card 1 and a power supply module 2, and detachably connecting the first side of the data management card 1 to the first electronic device 3 and the second side of the data management card 1 to the power supply module 2, allows the power supply module 2 to supply power to the data management card 1 when the first electronic device 3 is powered off, enabling the data management card 1 to store the data of the electronic device. Furthermore, a snap-fit ​​structure 223 connects the power supply module 2 and the crossbeam 34 of the first electronic device 3 together, ensuring that the data management card 1 and the power supply module 2 are stably stacked together and connected to the first electronic device 3, while avoiding occupying the connectable area on the connection side between the first electronic device 3 and the data management card 1.

[0068] like Figure 1As shown, in some modified embodiments of this disclosure, the power supply module 2 includes a battery assembly 21 and a support frame 22. The support frame 22 is disposed on the side of the battery assembly 21 away from the data management card 1, and a snap-fit ​​structure 223 is provided at one end of the support frame 22. The support frame 22 has a first connecting arm 222 and a second connecting arm 221, which are perpendicular to each other. The snap-fit ​​structure 223 is disposed at one end of the first connecting arm 222, and the second connecting arm 221 is used to connect with the side beam 33 of the first electronic device 3.

[0069] Battery assembly 21 is the core component of power supply module 2, responsible for providing backup power to data management card 1. It can immediately take over the power supply task when the main power fails, ensuring that uncommitted data in the cache can be safely written to non-volatile memory, preventing data loss. Battery assembly 21 is located on the second side of data management card 1 (i.e., the side away from the first side interface) and maintains close contact with data management card 1 to supply power to it via wires or interfaces.

[0070] The main function of the support frame 22 is to provide mechanical support for the battery assembly 21 and to fix it to the crossbeam 34 and side beam 33 of the first electronic device 3 via the snap-fit ​​structure 223. The support frame 22 not only enhances the stability of the power supply module 2 but also simplifies the installation and disassembly process. The support frame 22 is positioned on the side of the battery assembly 21 away from the data management card 1, ensuring that it does not interfere with the connection between the data management card 1 and the host system.

[0071] The first connecting arm 222 is a major component of the support frame 22. Its main function is to support the snap-fit ​​structure 223 and securely fix the power supply module 2 to the crossbeam 34 of the first electronic device 3. One end of the first connecting arm 222 is provided with the snap-fit ​​structure 223 for mechanical connection with the crossbeam 34 of the first electronic device 3. The snap-fit ​​structure 223 can be a push-pull type, a spring-loaded type, or other type of locking mechanism to ensure that the power supply module 2 will not loosen or fall off after installation. To prevent loosening due to vibration or external force, the snap-fit ​​structure 223 may also include a locking device (such as a screw, spring clip, etc.) to further enhance the reliability of the connection.

[0072] The second connecting arm 221 is another major component of the support frame 22, and is positioned perpendicular to the first connecting arm 222. Its main function is to connect to the side beam 33 of the first electronic device 3, providing additional mechanical support and ensuring the stability of the power supply module 2 in multiple directions. One end of the second connecting arm 221 is designed with a dedicated interface or slot for connecting to the side beam 33 of the first electronic device 3. This design not only increases the stability of the power supply module 2 but also distributes the stress points, reducing pressure on any single connection point.

[0073] Specifically, a shock-absorbing structure can also be provided on the side of the support frame 22 away from the battery assembly 21. The shock-absorbing structure is used to connect with the outer shell of the chassis 32 to absorb and disperse vibration energy, thereby reducing the vibration transmitted to the battery assembly 21. More specifically, the shock-absorbing structure can be a rubber block, such as a rubber pad, spring, airbag, hydraulic damper, etc.

[0074] like Figure 2 and Figure 3 As shown, in some modified embodiments of this disclosure, the snap-fit ​​structure 223 includes a snap-fit ​​body 2233, a first snap-fit ​​end 2231, a second snap-fit ​​end 2232, and a first snap hook 2234; the first snap-fit ​​end 2231 is disposed on the side of the snap-fit ​​body 2233 away from the battery assembly 21, and the first snap-fit ​​end 2231 snaps into the first through hole 341 of the crossbeam 34; the second snap-fit ​​end 2232 and the first snap-fit ​​end 2231 are disposed on the same side of the snap-fit ​​body 2233, the second snap-fit ​​end 2232 is disposed on the side of the first snap-fit ​​end 2231 away from the first connecting arm 222, and the second snap-fit ​​end 2232 snaps into the second through hole 342 of the crossbeam 34; the first snap hook 2234 is disposed on the side of the snap-fit ​​body 2233 close to the battery assembly 21; the first snap hook 2234 snaps into the side wall of the third through hole 343 of the crossbeam 34.

[0075] The snap-fit ​​body 2233 is the main frame of the snap-fit ​​structure 223, responsible for supporting other snap-fit ​​components and connected to the first connecting arm 222 of the support frame 22. It can be made of high-strength plastic or metal, possessing sufficient strength and durability to maintain stability in various environments. The snap-fit ​​body 2233 can snap into an opening on one side of the crossbeam 34, thus ensuring the stability of the snap-fit.

[0076] The first snap-fit ​​end 2231 is a key component of the snap-fit ​​structure 223, used to snap into the first through hole 341 on the crossbeam 34. It can be a protruding structure that can be inserted into and locked into the first through hole 341 of the crossbeam 34, ensuring that the power supply module 2 will not loosen after installation. It achieves initial mechanical fixation by inserting into the first through hole 341 of the crossbeam 34. The second snap-fit ​​end 2232 is another key component of the snap-fit ​​structure 223, used to snap into the second through hole 342 on the crossbeam 34. It can be designed as a hook-shaped structure similar to the first snap-fit ​​end 2231, but in a different position, further enhancing the stability of the power supply module 2. The second snap-fit ​​end 2232 and the first snap-fit ​​end 2231 are located on the same side of the snap-fit ​​body 2233, thereby further limiting the position of the power supply module 2 on this side. The two snap-fit ​​ends can perform double snap-fit ​​at different positions on the crossbeam 34, providing stronger mechanical support. The first hook 2234 is the third key component of the locking structure 223. It is used to engage with the side wall of the third through hole 343 on the crossbeam 34. It can be an elastic hook-shaped structure that can automatically lock after being inserted into the third through hole 343, preventing the power supply module 2 from falling off the crossbeam 34. The first hook 2234 is located on the side of the locking body 2233 near the battery assembly 21, that is, on the side opposite to the first locking end 2231 and the second locking end 2232, thereby limiting the power supply module 2 in this opposite direction. By engaging with the side wall of the third through hole 343 of the crossbeam 34, that is, engaging with the wall of the third through hole 343, it further enhances the fixing effect of the power supply module 2.

[0077] This disclosure not only limits the power supply module 2 through the locking structure 223 of the first locking end 2231, the second locking end 2232, and the first hook 2234, but also further limits the power supply module 2 by setting them in a relative positional relationship. This makes the power supply module 2 more firmly fixed on the crossbeam 34, enabling it to withstand greater external forces and vibrations, and is suitable for harsh environments such as industrial control and vehicle systems. The design of multiple locking points effectively distributes the stress points, reduces the pressure on individual locking points, and extends the service life of the locking structure 223.

[0078] Specifically, such as Figure 1 , Figure 7 As shown, a latch 2235 can be provided on the side of the snap-fit ​​body 2233 near the battery assembly 21. The opening of the latch 2235 faces the battery assembly 21. A latching plate can be provided at the opening of the crossbeam 34. The latching plate and the latch 2235 cooperate to limit the power supply module 2. That is, the first snap-fit ​​end 2231, the second snap-fit ​​end 2232, the first latch, and the latch 2235 limit the snap-fit ​​body 2233 in three mutually perpendicular directions, thereby limiting the power supply module 2 in three mutually perpendicular directions, making the power supply module 2 more firmly fixed on the crossbeam 34.

[0079] like Figure 4 As shown, in some modified embodiments of the first aspect of this disclosure, the second connecting arm 221 is provided with a first opening 224 on the side near the battery assembly 21, the first opening 224 being used to engage with one side of the side beam 33 of the first electronic device 3; the second connecting arm 221 is provided with a buckle 225 on the side away from the battery assembly 21, the buckle 225 being used to engage with the other side of the side beam 33 of the first electronic device 3.

[0080] The first opening 224 is a slot-shaped or hole-shaped structure on the side of the second connecting arm 221 near the battery assembly 21, used for engaging with one side of the side beam 33 of the first electronic device 3. It can be designed as an open slot capable of accommodating a portion of the side beam 33 and achieving mechanical fixation through a tight fit. The main function of the first opening 224 is to engage with one side of the side beam 33, providing initial mechanical fixation. When the second connecting arm 221 is inserted into the side beam 33, the first opening 224 tightly wraps around one side of the side beam 33, preventing the power supply module 2 from loosening in the horizontal direction. To enhance the engagement effect, the interior of the first opening 224 can be designed with anti-slip textures or elastic material to ensure that the power supply module 2 will not easily slip even in environments with significant vibration.

[0081] The latch 225 is a resilient locking device on the side of the second connecting arm 221 away from the battery assembly 21, used to engage with the other side of the side beam 33 of the first electronic device 3. It can be designed as a resilient hook-like structure that automatically locks after insertion into the side beam 33, preventing the power supply module 2 from detaching from the side beam 33. The main function of the latch 225 is to engage with the other side of the side beam 33, providing final mechanical fixation. When the second connecting arm 221 is inserted into the side beam 33, the latch 225 automatically pops out and locks on the other side of the side beam 33, ensuring that the power supply module 2 does not loosen in the vertical direction. For easy disassembly, the latch 225 can be equipped with a manual unlocking button or lever; the user can easily unlock and detach from the side beam 33 by simply pressing a button or pulling a lever.

[0082] More specifically, the side beam may include two parallel plate-like structures. The buckle 225 is snapped onto the upper plate-like structure, and the edge of the lower plate-like structure is vertically connected to a snap-fit ​​plate. The first opening 224 is snapped onto the snap-fit ​​plate, thereby facilitating the second connecting arm 211 to be snapped from top to bottom.

[0083] The design of the second connecting arm 221 further optimizes the connection between the power supply module 2 and the side beam 33 of the first electronic device 3. Specifically, the second connecting arm 221 has a first opening 224 on the side closer to the battery assembly 21 for engaging with one side of the side beam 33; while the side of the second connecting arm 221 away from the battery assembly 21 has a latch 225 for engaging with the other side of the side beam 33. This dual fixing point design not only provides reliable mechanical fixation but also simplifies the installation and disassembly process.

[0084] like Figure 1 , Figure 2 and Figure 3 As shown, in some modified embodiments of the first aspect of this disclosure, the first snap-fit ​​end 2231 and the second snap-fit ​​end 2232 respectively contact the sidewalls of the first through hole 341 and the second through hole 342 that are close to each other; the snap-fit ​​body 2233 is provided with an inclined surface on the side close to the first snap-fit ​​end 2231 so that the support frame 22 can rotate about the first snap-fit ​​end 2231.

[0085] By ensuring that the first latching end 2231 and the second latching end 2232 contact the sidewall of the through hole respectively, the latching structure 223 is automatically aligned upon insertion, reducing human error during installation. Furthermore, the contact between the first latching end 2231 and the second latching end 2232 and the sidewall of the through hole limits the relative direction of the two latching ends 2231 and 2232, preventing the latching body 2233 from moving in that direction.

[0086] The snap-fit ​​body 2233 has a sloped surface near the first snap-fit ​​end 2231. This sloped surface allows the support frame 22 to rotate around the first snap-fit ​​end 2231. The sloped surface can be a gradually sloping surface that gradually narrows from the outside to the inside of the snap-fit ​​body 2233. Specifically, during installation, the first snap-fit ​​end 2231 of the snap-fit ​​body 2233 can be installed in the first through hole 341 first. Then, the support frame 22 can be rotated around the first snap-fit ​​end 2231, so that the buckle 225 and the first opening 224 of the second connecting arm 221 snap onto the side beam 33 from top to bottom. At the same time, the first hook and the slot snap onto the third through hole 343 and the card plate from top to bottom. The second snap-fit ​​end 2232 snaps into the second through hole 342 from bottom to top, thus completing multi-point snap-fit ​​simultaneously for convenient installation. Furthermore, the three mutually perpendicular positions of the power supply module 2 are simultaneously limited, and the rotation direction is limited by the buckle 225, thus ensuring the stability of the connection while facilitating installation.

[0087] like Figure 5 and Figure 6As shown, in some modified embodiments of this disclosure, the battery assembly 21 includes a housing 211, a battery 212, and a battery cover 213. The housing 211 is connected to the support frame 22, and a second hook 2112 is provided inside the housing 211. The side wall of the battery 212 is engaged with the second hook 2112. The battery cover 213 is connected to the housing 211, and an accommodating space for accommodating the battery 212 is formed between the battery cover 213 and the housing 211.

[0088] The housing 211 is the external protective structure of the battery assembly 21, responsible for housing and securing the battery 212 and providing mechanical support. It can be made of high-strength plastic or metal, possessing good impact resistance and corrosion resistance, protecting the battery 212 from damage in various environments. The housing 211 not only provides physical protection for the battery 212 but also ensures the stability of the entire power supply module 2 through its connection with the support frame 22. The strength and rigidity of the housing 211 can withstand external forces and vibrations, preventing the battery 212 from loosening or falling off during operation. The housing 211 has good electrical insulation properties, preventing the battery 212 from contacting external conductive parts and avoiding short circuits or other electrical faults.

[0089] Battery 212 is the core component of battery assembly 21, responsible for providing backup power to data management card 1. It can be a lithium battery 212, a supercapacitor, or other types of energy storage components, depending on the application requirements. Battery 212 immediately takes over power supply when the main power fails, ensuring that uncommitted data in the cache can be safely written to non-volatile memory, preventing data loss. The sidewall of battery 212 is designed with a structure that matches the second latch 2112 inside housing 211, allowing battery 212 to be securely fixed within housing 211, preventing displacement under vibration or external force.

[0090] The battery cover 213 is part of the housing 211 and is responsible for sealing the battery 212 housing space, providing additional mechanical protection and a sealing effect. The battery cover 213 can be connected to the housing 211 by clips 225, screws, or other fixing methods to ensure that it will not loosen after installation. The tight fit between the battery cover 213 and the housing 211 can prevent external contaminants such as dust and moisture from entering the battery 212 housing space, extending the service life of the battery 212.

[0091] The second latch 2112 is an elastic locking device inside the housing 211, used to engage with the side wall of the battery 212. It can be designed as a flexible hook-like structure that automatically locks when the battery 212 is inserted, preventing it from falling out of the housing 211. The second latch 2112 is located inside the housing 211, close to the side wall of the battery 212, ensuring that the battery 212 can be smoothly latched and secured during insertion. The main function of the second latch 2112 is to engage with the side wall of the battery 212, ensuring that the battery 212 is firmly fixed within the housing 211 and preventing it from shifting under vibration or external force. Even in harsh working environments, the battery 212 remains stable.

[0092] The accommodating space refers to the enclosed area formed between the battery cover 213 and the housing 211, used to house the battery 212. The design of this space must ensure that the battery 212 can be safely placed within it and that there is sufficient space for heat dissipation. The dimensions of the accommodating space should be optimized according to the specific dimensions of the battery 212, ensuring that the battery 212 fits tightly against the housing 211 while leaving appropriate gaps to facilitate heat dissipation. The accommodating space may be equipped with heat dissipation channels or ventilation holes to ensure that the battery 212 can effectively dissipate heat during high-load operation, preventing performance degradation or safety hazards caused by overheating.

[0093] like Figure 5 and Figure 6 As shown, in some modified embodiments of this disclosure, a first latching portion 2111 and a second latching portion 2113 are provided on the side wall of the housing 211; a third hook 2132 and a fourth hook 2133 are provided on the side of the battery cover 213 near the housing 211, and the third hook 2132 and the fourth hook 2133 are respectively provided with a second opening and a third opening on the side facing the first latching portion 2111 and the second latching portion 2113, and the second opening and the third opening respectively cooperate with the first latching portion 2111 and the second latching portion 2113; a third latching portion 2131 is also provided on the side of the battery cover 213 near the housing 211, and the third latching portion 2131 latches with the side wall of the housing 211 opposite to the opening direction of the second opening.

[0094] The first engaging portion 2111 is a fixing structure on the side wall of the housing 211. It can be designed as a protruding hook-shaped or groove-shaped structure for engaging with the third hook 2132 on the battery cover 213. The first engaging portion 2111 is located on the side wall of the housing 211, close to the installation position of the battery cover 213, ensuring that it can be aligned and engaged with the second opening on the third hook 2132. The main function of the first engaging portion 2111 is to engage with the second opening on the third hook 2132, providing initial mechanical fixation and ensuring that the battery cover 213 will not easily loosen after installation.

[0095] The second latching part 2113 is another fixing structure on the side wall of the housing 211. It can be designed as a hook-shaped or groove-shaped structure similar to the first latching part 2111, for engaging with the fourth hook 2133 on the battery cover 213. The main function of the second latching part 2113 is to engage with the third opening on the fourth hook 2133, providing additional mechanical fixation and enhancing the overall stability of the battery cover 213.

[0096] The third latch 2132 is an elastic locking device on the side of the battery cover 213 near the housing 211, used to engage with the first latching portion 2111 on the housing 211. It can be a groove-shaped structure, with its opening engaging with and enclosing the first latching portion 2111, thereby limiting the thickness of the battery cover 213. More specifically, the first latching portion 2111 can consist of mutually perpendicular vertical and horizontal sections; the opening encloses the horizontal section and contacts the vertical section, thus limiting the horizontal direction. The main function of the third latch 2132 is to engage with the second opening on the first latching portion 2111, providing initial mechanical fixation and ensuring that the battery cover 213 will not easily loosen after installation.

[0097] The fourth latch 2133 is another resilient locking device on the side of the battery cover 213 near the housing 211, used to engage with the second latching portion 2113 on the housing 211. It can be designed as a hook-like structure similar to the third latch 2132, but positioned opposite to it, ensuring alignment and engagement with the third opening on the second latching portion 2113. The main function of the fourth latch 2133 is to engage with the third opening on the second latching portion 2113, providing additional mechanical fixation and enhancing the overall stability of the battery cover 213.

[0098] The second and third openings are groove-shaped or hole-shaped structures provided on the side of the third hook 2132 and the fourth hook 2133 facing the housing 211, respectively, for engaging with the first latching part 2111 and the second latching part 2113 on the housing 211. They can be designed as open slots to accommodate the latching parts on the housing 211 and achieve mechanical fixation through a tight fit.

[0099] The third latching part 2131 is another fixing structure of the battery cover 213 near the housing 211, used to latch against the side wall of the housing 211 opposite to the opening direction of the second opening. It can be designed as an elastic hook-shaped or groove-shaped structure that can automatically lock when inserted into the housing 211, preventing the battery cover 213 from falling off. Specifically, the third latching part 2131 can be a beveled block structure that can elastically deform. When the battery cover 213 slides, the thinner side of the beveled block structure first contacts the side wall of the housing 211 and elastically deforms, allowing the battery cover 213 to continue sliding so that the thicker side of the beveled block structure latches onto the side wall of the housing 211, thereby cooperating with the first latching part 2111 to limit the sliding direction. The third latching part 2131 can also be a groove-shaped structure, latching onto the side wall of the housing 211 while simultaneously limiting the forward and backward sliding direction of the battery cover 213.

[0100] In some modified embodiments of this disclosure, the battery assembly 21 further includes a connector, a hub, and multiple connecting wires. The multiple connecting wires connect the battery 212 and the connector, and the hub is disposed outside the multiple connecting wires. A through hole is provided on the side wall of the housing 211, through which the connector passes to connect to the data management card 1. These added components enable the battery assembly 21 to make an electrical connection with the data management card 1 more efficiently, and the hub manages and protects the multiple connecting wires.

[0101] The connector is the electrical interface between the battery pack 21 and the data management card 1, responsible for transmitting power supplied by the battery 212 to the data management card 1. It can be a standardized plug or socket, compatible with the corresponding interface on the data management card 1. The connector is located at a through-hole on the side wall of the housing 211, passing through the through-hole to connect to the data management card 1. The through-hole design ensures that the connector can pass smoothly through the housing 211 while maintaining a good seal to prevent external contaminants from entering the battery pack 21.

[0102] A hub is a centralized management and protection device for multiple connecting cables, located on the outside of the cables. It is responsible for consolidating multiple connecting cables together, reducing cable clutter, and providing additional mechanical protection. Positioned on the outside of the multiple connecting cables, close to the battery 212 and the connector, the hub ensures that the connecting cables are neatly arranged, preventing them from becoming tangled or being pulled by external forces.

[0103] Example 2

[0104] like Figure 7As shown, an electronic device includes a power failure protection device and a first electronic device 3. The first electronic device 3 includes a chassis 32 and a motherboard 31, with the motherboard 31 disposed on one side of the chassis 32. A crossbeam 34 is disposed on the side of the chassis 32 away from the motherboard 31, with both ends of the crossbeam 34 connected to the side wall of the chassis 32. The power failure protection device includes a data management card 1 and a power supply module 2. The first side of the data management card 1 is detachably connected to the first electronic device 3. The power supply module 2 is disposed on the second side of the data management card 1. A snap-fit ​​structure 223 is disposed at one end of the power supply module 2, and the snap-fit ​​structure 223 snaps into the crossbeam 34 of the first electronic device 3. The second side is the side opposite to the first side. When the first electronic device 3 is powered off, the power supply module 2 supplies power to the data management card 1 so that the data management card 1 can save the data of the electronic device.

[0105] The specific structure of the power failure protection device can be the same as that in Embodiment 1, and will not be described again here. The chassis 32 is the outer shell of the first electronic device 3, responsible for housing and protecting internal components such as the motherboard 31, hard drive, and power supply. It can be made of metal or high-strength plastic, possessing good mechanical strength and heat dissipation performance. The chassis 32 provides physical protection for the internal components, preventing damage to the equipment from external impacts, dust, moisture, etc. The chassis 32 can be designed with ventilation holes or fans to ensure effective heat dissipation of the internal components during high-load operation, preventing performance degradation or safety hazards caused by overheating.

[0106] The motherboard 31 is the core circuit board of the first electronic device 3, responsible for connecting and controlling various hardware components, such as the CPU (Central Processing Unit), memory, hard drive, and network interface. It is the central hub of the entire system, responsible for processing and transmitting data. The motherboard 31 is located on one side of the chassis 32 and can be connected to the inner wall of the chassis 32 using screws or other fixing methods to ensure it remains secure after installation. The motherboard 31 processes data from various hardware components and transmits the results to other devices or storage media. The motherboard 31 also manages power distribution, ensuring a stable power supply to all components.

[0107] like Figure 7 As shown, this disclosure, by setting up a data management card 1 and a power supply module 2, and detachably connecting the first side of the data management card 1 to the first electronic device 3 and the second side of the data management card 1 to the power supply module 2, allows the power supply module 2 to supply power to the data management card 1 when the first electronic device 3 is powered off, so that the data management card 1 can save the data of the electronic device. Furthermore, the power supply module 2 and the crossbeam 34 on the side of the chassis 32 of the first electronic device 3 away from the motherboard 31 are connected together by a snap-fit ​​structure 223, so that the data management card 1 and the power supply module 2 are stably stacked together and connected to the first electronic device 3, avoiding occupying the connectable area on the side of the motherboard 31 where the data management card 1 is connected, thereby allowing the motherboard 31 to connect to more devices.

[0108] like Figure 7 As shown, in some modified embodiments of this disclosure, an air inlet assembly 5 and an air outlet assembly 6 are also included. The air inlet assembly 5 is disposed on the side wall of the chassis 32, and the air outlet assembly 6 is disposed on the crossbeam 34. A power failure protection device is disposed between the air inlet assembly 5 and the air outlet assembly 6.

[0109] The air intake assembly 5 is a ventilation device on the side wall of the chassis 32. It can be equipped with a fan or a heat dissipation mesh to introduce external cool air and help dissipate heat from the components inside the chassis 32. The air intake assembly 5 is located on the side wall of the chassis 32, near the power failure device, ensuring that cool air can directly enter the area surrounding the power failure device. The main function of the air intake assembly 5 is to introduce external cool air to help dissipate heat from the components inside the chassis 32, especially the battery 212 and electronic components in the power failure device. The air intake assembly 5 can also be equipped with a filter to prevent dust from entering the chassis 32 and extend the lifespan of the components.

[0110] The exhaust assembly 6, a ventilation device mounted on the crossbeam 34, can also be equipped with a fan or heat dissipation mesh to expel the heat generated by the power failure protection device, ensuring effective heat dissipation during high-load operation. Located on the crossbeam 34, near the opposite side of the power failure protection device, the exhaust assembly 6 ensures hot air can be exhausted from inside the chassis 32, preventing heat accumulation and ensuring effective heat dissipation during high-load operation, thus preventing performance degradation or safety hazards caused by overheating. The design of the exhaust assembly 6 can incorporate airflow optimization to ensure that cool air can pass smoothly through the power failure protection device, carrying away heat and maintaining the component's low-temperature state.

[0111] Cool air enters the chassis 32 through the air intake assembly 5, passes through the power-off protection device, and is finally exhausted from the air outlet assembly 6. This ensures that the power-off protection device remains at a low temperature during operation, extending its service life and improving system stability. Through a well-designed airflow path, cool air directly contacts key components of the power-off protection device, such as the battery 212 and electronic components, carrying away heat and maintaining the components' low temperature. The airflow path design also considers preventing heat buildup, ensuring that hot air is quickly exhausted from the chassis 32, preventing heat from flowing back to the power-off protection device and affecting its performance.

[0112] Specifically, such as Figure 8 and Figure 9As shown, the air intake assembly 5 may include an air intake fan 52 and an air intake bracket 51 connected to each other. The air intake bracket 51 is provided with multiple sets of first mounting holes 511, each set of first mounting holes 511 capable of mounting at least one type of air intake fan 52. Similarly, the air outlet assembly 6 includes an air outlet fan and an air outlet bracket connected to each other. The air outlet bracket is provided with multiple sets of second mounting holes, each set of second mounting holes capable of mounting at least one type of air outlet fan. This allows the air intake assembly 5 and the air outlet assembly 6 to be compatible with different types of air intake fans 52 and air outlet fans. For example, the first set of mounting holes 5111 is compatible with a fan with a length and width of 90cm, and the second set of mounting holes 5112 is compatible with a fan with a length and width of 80cm. The first set of mounting holes 5111 can be installed at the four corners of the bracket, and the second set of mounting holes 5112 can be installed at the center of the four sides of the bracket, thus adapting to different types of fans while avoiding the mounting holes being too close together, which would affect the strength of the bracket.

[0113] More specifically, such as Figure 10 As shown, for a square fan, the first mounting hole 511 or the second mounting hole can be set as an angled hole, with multiple angled holes extending towards the center of the fan, so that the mounting hole can be adapted to different types of square fans.

[0114] like Figure 7 As shown, in some modified embodiments of this disclosure, a graphics card assembly and a graphics card bracket 4 are also included. The graphics card assembly is connected to the motherboard 31. One end of the graphics card bracket 4 is connected to the crossbeam 34. One side of the graphics card bracket 4 is connected to the graphics card assembly, and the other side of the graphics card assembly contacts the air outlet assembly 6 to support the air outlet assembly 6.

[0115] The graphics card component is the graphics processing unit in an electronic device, responsible for processing and rendering graphics data such as images and videos. It connects to the motherboard 31 via a slot, providing powerful graphics processing capabilities suitable for applications requiring high-performance graphics processing, such as gaming, video editing, and virtualization. Specifically, the graphics card component is located in the expansion slot area of ​​the motherboard 31. One side of the graphics card component connects to the graphics card bracket 4, and the other side contacts the exhaust component 6, supporting the exhaust component 6.

[0116] The graphics card bracket 4 is the supporting structure for the graphics card assembly, responsible for securing the graphics card assembly within the chassis 32 and providing additional mechanical support. One end of the graphics card bracket 4 is connected to the crossbeam 34, and the other end is connected to the graphics card assembly, ensuring that the graphics card assembly will not loosen or fall off due to gravity or vibration during high-load operation. The other side of the graphics card bracket 4 contacts the graphics card assembly, supporting the exhaust assembly 6 and ensuring that the exhaust assembly 6 will not loosen or fall off due to gravity or vibration during high-load operation.

[0117] By rationally designing the power failure protection device, the heat dissipation system, and the various components and connection methods of the graphics card assembly, combined with the support of the efficient heat dissipation system and the graphics card bracket 4, it is possible to ensure that electronic devices remain stable in various working environments and improve the overall performance and reliability of the system.

[0118] In some modified embodiments of this disclosure, a slider 10 is provided on the side wall of the air intake component 5, and a guide rail 9 is provided on the side wall of the chassis 32, with the slider 10 slidably connected to the guide rail 9; a slot is provided on the side of the air intake component 5 away from the motherboard 31, and an elastic buckle is provided on the side wall of the chassis 32, with the elastic buckle matching the slot; wherein, when the air intake component 5 slides to a set position, the elastic buckle pops out and engages in the slot.

[0119] A slider 10 is provided on the side wall of the air intake assembly 5. The slider 10 is slidably connected to the guide rail 9 on the side wall of the chassis 32, allowing the air intake assembly 5 to be easily installed and removed. The guide rail 9 is a sliding track on the side wall of the chassis 32, used to cooperate with the slider 10 of the air intake assembly 5, allowing the air intake assembly 5 to slide along the guide rail 9 for easy installation and removal. The guide rail 9 also provides stable support for the air intake assembly 5, ensuring that it will not loosen or fall off after installation. Specifically, as shown... Figure 9 As shown, the guide rail 9 can be segmented with hooks along the sliding direction to reduce weight, and the slider 10 is slidably connected within the hooks. The slider 10 can be arranged around the air inlet bracket to improve the stability of the bracket structure and the stability of the sliding connection.

[0120] The elastic latch is a spring-loaded locking device on the side wall of the chassis 32, used to engage with the slot of the air intake assembly 5 to ensure that the air intake assembly 5 is securely fixed after sliding to the set position. When the air intake assembly 5 slides to the set position, the elastic latch automatically pops out and locks into the slot, ensuring that the air intake assembly 5 is securely fixed. For easy disassembly, the elastic latch can be equipped with a manual unlocking button or lever. The user can easily unlock and remove the air intake assembly 5 by simply pressing a button or pulling a lever.

[0121] like Figure 9 As shown, a flexible latch 8 can also be provided on the side of the air intake component 5 away from the motherboard 31, and a snap-fit ​​groove 7 is provided on the side wall of the chassis 32, with the flexible latch 8 fitting into the snap-fit ​​groove 7; wherein, when the air intake component 5 slides to the set position, the flexible latch 8 pops out and snaps into the snap-fit ​​groove 7. Specifically, the flexible latch 8 can be a hook extending from the air intake bracket, protruding from the connecting surface of the air intake bracket. When the air intake bracket is not slid to the set position, the hook elastically deforms to be on the same horizontal plane as the connecting surface of the air intake bracket; when the air intake bracket slides to the set position, the hook resets and snaps into the snap-fit ​​groove 7. More specifically, the hook can be handle-shaped, thereby facilitating the removal of the air intake component.

[0122] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
