DETAILED DESCRIPTION

[0020] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0022] In the present application, unless otherwise specified, the orientation such as “up, down” is generally directed to the direction shown in the drawings, or is directed to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, “left, right” is generally directed to the left and right shown in the drawings; “inner, outer” refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0023] Please refer to Figure 1 The present application provides the following technical solutions: Specifically, it refers to a cross-border e-commerce accounting data storage system, including a data acquisition module, a data integration module, a transaction data processing module, a ledger module, a record storage module, and a database server. The data acquisition module is used to connect to mainstream e-commerce platforms (Amazon, eBay, Shopify, WooCommerce, Alibaba International Station, AliExpress, etc.), payment gateways (PayPal, Stripe, Worldpay, Alipay International Version, etc.), logistics service providers (DHL, FedEx, UPS, postal parcels, etc.), overseas warehouse systems, bank accounts, ERP systems (such as NetSuite, SAP, etc.), thereby collecting relevant data on cross-border e-commerce orders. The data acquisition module is connected to the data integration module, so the data integration module can convert heterogeneous data from different sources into a unified internal format (standardized fields, currencies, date formats, etc.), which facilitates the subsequent processing of this data.

[0024] The data integration module is connected to the transaction data processing module. The transaction data processing module includes an order matching module, a cost allocation module, a currency processing module, and a tax calculation module. The order matching module can automatically match orders, payment records, and logistics tracking information (at the time of revenue confirmation). The cost allocation module automatically identifies platform commissions, payment processing fees, logistics costs, customs duties, marketing expenses, overseas warehouse storage fees, etc., and accurately allocates them to the corresponding orders or products. Due to the involvement of cross-border e-commerce, the currency processing module obtains and updates exchange rates in real time, records transaction currencies, and converts them to the base currency (supporting multiple base currencies). The system allows for currency settings (e.g., by company entity / store), automatic calculation and recording of exchange gains and losses (by accounting period), and finally, a tax calculation module that automatically determines the applicable VAT / Sales Tax / GST rates and rules based on transaction location (shipping location / receiving location), product type, buyer information, etc., automatically calculates the transaction tax amount, and generates tax reports that meet the requirements of various countries (e.g., EU VAT return). By setting up a transaction data processing module, it can support multi-currency processing and accurate exchange gains and losses calculation, meeting the requirements of accounting regulations and tax regulations (e.g., VAT / GST, income tax) of different countries / regions.

[0025] The transaction data processing module is connected to the ledger module. The ledger module performs detailed classification based on the data processed by the transaction data processing module. It supports multiple companies, multiple ledgers, and multiple accounting standards (such as Chinese standards, IFRS, and US GAAP in parallel), with a complete account system to adapt to the characteristics of cross-border e-commerce (such as cross-border settlement accounts, platform receivables, revenue to be confirmed, deferred tax, etc.).

[0026] The ledger module and the record storage module are connected. The record storage module securely stores all original electronic vouchers (electronic invoices, platform order screenshots, payment voucher screenshots, logistics waybills, customs documents, contracts, etc.), automatically links the original vouchers with the corresponding transaction records and accounting vouchers to form a complete chain of evidence, and records the source, generation time, modification records, etc. of the vouchers. Finally, it automatically generates profit and loss statements, balance sheets, and cash flow statements (by company entity, store, region, etc.).

[0027] The record saving module is connected to the database server. All the data generated by the record saving module is stored on the database server. The database server is equipped with an indexing and search module, which can quickly locate data by date, amount, order number, customer name, voucher type, etc.

[0028] The aforementioned cross-border e-commerce accounting data storage system can be used to organize and analyze cross-border e-commerce transaction data in detail, ensuring that all transaction data (orders, payments, logistics, refunds, fees) are accurately recorded and converted. It supports multi-currency processing and accurate exchange rate profit and loss calculation, and meets the accounting regulations, tax regulations (such as VAT / GST, income tax), data privacy laws (such as GDPR, CCPA), and electronic record storage requirements of different countries / regions, facilitating the storage of e-commerce transaction data.

[0029] Please see Figures 2-8 The present invention provides a new technical solution based on the above-mentioned scheme: a database server, including a housing 1, with multiple rectangular arrayed embedding slots 2 on the front surface of the housing 1, into which a hard disk 3 is inserted. The outer surface of the hard disk 3 is in contact with the inner wall of the embedding slot 2. The hard disk 3 and the embedding slot 2 can be fixed by bolts or a snap-fit ​​structure. The snap-fit ​​structure is a conventional structure and will not be described in detail here. At the same time, a heat-conducting plate is embedded in the top of the hard disk 3 and extends into the hard disk 3. The heat-conducting plate is made of a material with high thermal conductivity. The main control chip and motherboard of the hard disk 3 are installed at the bottom of the heat-conducting plate. Therefore, when the hard disk 3 is in use, the heat generated by the main control chip and motherboard can be conducted away through the heat-conducting plate. A socket 6 is provided on the rear inner wall of the embedding slot 2. The number of sockets 6 is set according to the actual interface on the existing hard disk 3, generally two, including a SATA socket for connecting to the hard disk SATA interface and a power socket for connecting to the power interface. The socket 6 is electrically connected to the database motherboard inside the housing 1.

[0030] A blower 5 for blowing cold air into the housing 1 is embedded in the rear side of the housing 1. At the same time, a dustproof net (not shown in the figure) for isolating dust is provided on the rear side of the blower 5. Multiple heat-conducting cavities 45 are opened in the housing 1 between the embedded groove 2 and the interior of the housing 1. The heat-conducting cavities 45 are located on the rear side of the vertically arranged embedded groove 2. Multiple ventilation slots 47 are opened between the heat-conducting cavities 45 and the interior of the housing 1. When the blower 5 blows cold air into the housing 1, the air can enter the heat-conducting cavities 45 through the ventilation slots 47. A heat-absorbing component is provided in the heat-conducting cavity 45. The heat-absorbing component can absorb the heat in the air entering the heat-conducting cavity 45, thereby achieving the purpose of cooling the air in the heat-conducting cavity 45.

[0031] Multiple flow grooves 7 are provided on the front inner wall of the heat conduction cavity 45. The flow grooves 7 are located directly above the embedded groove 2. The top of the embedded groove 2 is provided with a movable groove 9. The bottom wall of the flow groove 7 is provided with a connecting cavity 8 that communicates with the movable groove 9. The front inner wall of the movable groove 9 is provided with an air outlet 91 that extends out of the outer surface of the shell 1.

[0032] During use, after the airflow passes through the heat-conducting cavity 45, the heat-absorbing component absorbs most of the heat in the airflow. This airflow, after passing through the heat-absorbing component, flows into the flow channel 7, then through the connecting cavity 8, and finally into the movable slot 9. Since the hard disk 3 is inserted into the embedded slot 2 and fits against the inner wall of the embedded slot 2, an airflow cavity is formed between the top of the hard disk 3 and the movable slot 9. The air entering the movable slot 9 flows towards the air outlet 91 within the airflow cavity. At the same time, a heat-conducting plate is provided on the top of the hard disk 3. The airflow contacts the heat-conducting plate, thereby carrying away the heat absorbed by the heat-conducting plate, thus achieving the purpose of cooling the hard disk 3. The above-mentioned airflow channel, combined with the heat dissipation components in the existing database server, directly optimizes the heat dissipation of the hard disk (especially the hard disks deployed in high density). This is significantly different from the static heat dissipation of traditional hard disks, ensuring the stability of the hard disk when using cross-border e-commerce accounting data in high-load operation scenarios such as month-end summarization. It minimizes the problem of hard disk failure due to untimely heat dissipation and reduces the occurrence of abnormalities in the operation of the cross-border e-commerce accounting data storage system.

[0033] The circulation slot 7 is equipped with a sealing component that can block the connecting cavity 8. When the hard drive 3 is not inserted into the embedding slot 2, the sealing component automatically blocks the connecting cavity 8, preventing the cooling airflow from being lost (leaking) through the empty slot. This avoids the waste of cooling energy and improves the energy efficiency of the entire cooling system. When the hard drive 3 is inserted into the embedding slot 2, the sealing component automatically opens, accurately guiding the cooling airflow to the hard drive and its surrounding area, thus improving heat dissipation efficiency.

[0034] The sealing assembly includes a connecting plate 71. A connecting rod 72 is provided on the lower surface of the connecting plate 71 facing the connecting cavity 8. A baffle 73 is provided at the lower end of the connecting rod 72, which can cover the upper side of the connecting cavity 8. A rubber block 74 is provided on the lower surface of the baffle 73, which can be inserted into the connecting cavity 8. Multiple control cavities 75 are opened on the front side of the housing 1. The control cavities 75 are located between the embedded groove 2 and the heat conduction cavity 45. A push rod 77 is provided on the lower surface of the connecting plate 71 near the control cavity 75. The lower end of the push rod 77 slides through into the control cavity 75. A tension spring 79 is provided between the connecting plate 71 and the bottom wall of the flow channel 7, which is movably sleeved on the outer surface of the push rod 77. When the tension spring 79 is not affected by tension, the tension spring 79 will generate tension on the connecting plate 71, so that the initial position of the connecting plate 71 is close to the bottom of the flow channel 7. At this time, the baffle 73 covers the top of the connecting cavity 8, and the rubber block 74 is inserted into the connecting cavity 8, thereby achieving the purpose of sealing the connecting cavity 8.

[0035] A push rod 76 is provided inside the control cavity 75. The front end of the push rod 76 slides through the embedded groove 2 and can contact the rear surface of the hard disk 3. A rotating plate 78 is hinged between the rear end of the push rod 76 and the lower end of the push rod 77. When the hard disk 3 is inserted into the embedded groove 2, the rear side of the hard disk 3 contacts the front end of the push rod 76 and pushes the push rod 76 to move backward. At this time, the rotating plate 78 will exert an upward pushing force on the push rod 77, thereby pushing the connecting plate 71 to move upward. At the same time, the rubber block 74 moves out of the connecting cavity 8, and the baffle 73 no longer covers the connecting cavity 8, so that the cooling air can flow through the connecting cavity 8 to the movable groove 9.

[0036] A mounting plate 710 is provided on the front side of the flow channel 7. The lower surface of the mounting plate 710 is provided with multiple heat-conducting fins 711 arranged horizontally. The lower sides of the multiple heat-conducting fins 711 slide through into the movable channel 9 and can contact the heat-conducting plate on the top of the hard drive 3. The heat-conducting fins 711 are made of the same material as the heat-conducting plate. When the mounting plate 710 pushes the heat-conducting fins 711 down into the movable channel 9 and contacts the heat-conducting plate of the hard drive 3, the heat absorbed by the heat-conducting plate can be conducted to the heat-conducting fins 711. Since the multiple heat-conducting fins 711 are arranged horizontally, the movable channel 9 can be divided into multiple flow channels. In this way, the cooling air flowing in the movable channel 9 flows in multiple flow channels, which increases the heat dissipation area of ​​the hard drive 3, ensures the active heat dissipation efficiency of the hard drive 3, and guarantees the service life of the hard drive 3.

[0037] A rotating shaft 712 is rotatably connected between the inner walls of the left and right sides of the flow channel 7. The rotating shaft 712 is located between the connecting plate 71 and the mounting plate 710. A first gear 713 is sleeved on the outer surface of the rotating shaft 712. A first rack 714 that meshes with the first gear 713 is provided on the side of the connecting plate 71 near the first gear 713. A second rack 715 that meshes with the first gear 713 is provided on the side of the mounting plate 710 near the first gear 713.

[0038] In use, when the connecting plate 71 moves upward, the first rack 714 moves upward synchronously with the connecting plate 71. At this time, the first rack 714 can mesh with the first gear 713 to rotate counterclockwise. Thus, the first gear 713 meshes and drives the second rack 715 to move downward. Therefore, the mounting plate 710 pushes the multiple heat-conducting fins 711 downward. When the hard disk 3 is fully inserted into the embedding slot 2, the connecting plate 71 moves to its highest point, and the heat-conducting fins 711 move downward to contact the heat-conducting plate on the hard disk 3. When the connecting plate 71 moves downward, the first rack 714 can mesh with the first gear 713 to move forward. The mounting plate 710 is moved upwards by rotating clockwise, and the heat-conducting fins 711 move upwards simultaneously without contacting the heat-conducting plate. Through the above structure, when the hard disk 3 is inserted into the embedding slot 2, the heat-conducting fins 711 are automatically controlled to contact the heat-conducting plate on the hard disk 3. When the hard disk 3 is removed, the heat-conducting fins 711 move upwards without contacting the hard disk 3. This avoids the problem of continuous friction between the heat-conducting plate at the top of the hard disk 3 and the bottom of the heat-conducting fins 711 during the insertion of the hard disk 3 into the embedding slot 2, which would cause wear on the bottom of the heat-conducting fins 711. This ensures the heat conduction efficiency between the heat-conducting fins 711 and the heat-conducting plate.

[0039] The heat-absorbing component includes multiple microfins 46, the lower ends of which are rotatably connected to the heat-conducting cavity 45. The multiple microfins 46 are arranged in a 32323 layout (see attached diagram). Figure 6 The top of the housing 1 is provided with a heat-conducting housing 41, and multiple heat-conducting air ducts 42 are provided inside the heat-conducting housing 41. The heat-conducting air ducts 42 are shaped like two mirror-shaped horn combinations. Multiple exhaust fans 44 extending into the heat-conducting air ducts 42 are embedded in the rear side of the heat-conducting housing 41. A filter screen 43 is provided in the front side of the heat-conducting air ducts 42. The upper end of the micro needle fin 46 rotates through the heat-conducting air duct 42 and is located at the throat of the heat-conducting air duct 42.

[0040] When in use, the exhaust fan 44 is started and draws air from the heat conduction duct 42. The heat on the top of the micro-needle fin 46 is carried away by the airflow, making the temperature of the top of the micro-needle fin 46 lower than its temperature. According to the principle of heat conduction, the heat absorbed by the bottom of the micro-needle fin 46 is conducted into the heat conduction duct 42. In this way, the micro-needle fin 46 can continuously absorb heat from the heat conduction cavity 45, thereby achieving the purpose of cooling the air blown towards the hard disk 3, and minimizing the possibility that the temperature of the cooling air blown towards the hard disk 3 is too high, which would affect the cooling effect on the hard disk 3.

[0041] Meanwhile, since the heat conduction duct 42 is shaped like two mirrored horn combinations, the airflow is compressed by the inner wall when passing through the throat, and the airflow speed will be accelerated. In addition, the multiple micro needle fins 46 are arranged in a 32323 layout, which can improve the heat absorption efficiency of the micro needle fins 46.

[0042] A set of micro-needle fins 46 arranged in a front-to-back pattern each has a second gear 461 fitted on the outer surface of its lower end. Adjacent second gears 461 have a third rack 462 meshing with their outer surfaces. The rear side of the third rack 462 extends into a ventilation slot 47. A support plate 463 is provided on the bottom wall of the ventilation slot 47 near the third rack 462. A contact rod 464 is slidably fitted on the support plate 463. The front end of the contact rod 464 is connected to the rear side of the third rack 462. The rear end of the contact rod 464... A sleeve plate 465 is fitted on the surface, and a spring 466 is provided between the sleeve plate 465 and the support plate 463, which is movably fitted on the outer surface of the contact rod 464. An internal toothed ring 469 is provided on the bottom wall of the ventilation groove 47. The rear end of the contact rod 464 contacts the outer surface of the internal toothed ring 469 and slides. An arc-shaped protrusion 4610 is provided on the outer surface of the internal toothed ring 469. The arc-shaped protrusion 4610 is an isosceles triangle. The rear end of the contact rod 464 can slide onto the arc-shaped protrusion 4610.

[0043] When the internal gear ring 469 is rotated, the arc-shaped protrusion 4610 rotates synchronously with the internal gear ring 469. When the inclined surface of the arc-shaped protrusion 4610 contacts the contact rod 464, the arc-shaped protrusion 4610 will exert a thrust on the contact rod 464, causing the contact rod 464 to push the third rack 462 forward. At the same time, the spring 466 contracts, so the third rack 462 can mesh with the second gear 461 to rotate. The micro-needle fin 46 rotates synchronously with the second gear 461, thereby achieving the purpose of controlling the changing surface of the micro-needle fin 46. This increases the contact surface between the micro-needle fin 46 and the airflow blown into the heat conduction cavity 45, ensuring the heat absorption efficiency of the micro-needle fin 46 for the cooling airflow.

[0044] A mounting shaft 467 is rotatably connected to the top wall of the ventilation slot 47. A fan blade 468 is provided at the lower end of the mounting shaft 467. A drive shaft 4611 is provided on the lower surface of the fan blade 468. The lower end of the drive shaft 4611 extends into the internal gear ring 469. A first pinion 4612 is provided at the lower end of the drive shaft 4611. A plurality of second pinions 4613 are meshed between the outer surface of the first pinion 4612 and the internal gear ring 469. A gear shaft that is rotatably connected to the bottom wall of the ventilation slot 47 is provided on the lower surface of the second pinion 4613.

[0045] When in use, the air inside the housing 1 enters the heat conduction cavity 45 through the ventilation slot 47. The airflow will generate thrust on the blades of the fan 468, thereby driving the fan 468 to rotate. The transmission shaft 4611 synchronously drives the first pinion 4612 to rotate. The internal gear ring 469 rotates synchronously under the transmission of the first pinion 4612 and the second pinion 4613. Through the above structure, the transmission structure between the fan blade 468 and the internal gear ring 469 is a planetary gear set, which can slowly drive the internal gear ring 469 to rotate. Therefore, it synchronously drives the micro needle fin 46 to slowly change its surface, avoiding the micro needle fin 46 from rotating too fast and affecting its heat conduction efficiency.

[0046] The bottom wall of the ventilation slot 47 is provided with a support ring 4614, the upper surface of the support ring 4614 is provided with an annular groove 4615, and the lower surface of the internal toothed ring 469 is provided with a plurality of support pulleys 4616. The lower side of the support pulleys 4616 extends into the annular groove 4615 and contacts the bottom wall of the annular groove 4615, thereby supporting the internal toothed ring 469.
