Description

Technical Field

[0001] This application relates to the field of servers, and in particular to a chassis, a method for switching the chassis thereon, and a server. Background Technology

[0002] With the development of technology, the demand for servers is increasing year by year, and customers' demand for server equipment security is also becoming stronger. Therefore, how to improve the security of server use has become a requirement for server suppliers to enhance the differentiated competitiveness of their products.

[0003] Currently, the conventional method for fixing the top cover of a server chassis involves riveting I-beams into corresponding slots on the side wall of the chassis, and locking it to the chassis via a lock in the middle of the top cover. To remove the top cover, the screws of the top cover lock must be turned and the top cover lock pulled up. This design is not only cumbersome to disassemble, but also has poor equipment security. Although there is a switch, it does not have a real physical anti-theft function, making it very easy for criminals to disassemble and steal important components and core data inside the server, posing a certain security risk. Summary of the Invention

[0004] Based on this, this application provides a chassis, a control method thereof, and a server to improve the security performance of the server.

[0005] On one hand, a chassis is provided, the chassis including an outer shell and a top cover, and a fingerprint lock is connected between the outer shell and the top cover; the fingerprint lock includes a fingerprint recognition device and a motor assembly that are communicatively connected to each other, a slide rail is slidably connected inside the outer shell, and the output shaft of the motor assembly is movably connected to the slide rail; a first locking groove is provided on the slide rail, a second locking groove is provided on the outer shell, and a locking rod is provided on the top cover, the first locking groove, the second locking groove and the locking rod cooperating to control the unlocking or locking of the outer shell and the top cover.

[0006] In one embodiment, the motor assembly is disposed within the housing, a gear is connected to the output shaft of the motor assembly, and a meshing hole is provided on the slide rail to mesh with the gear, the gear and the meshing hole forming a transmission mechanism.

[0007] In one embodiment, a fixed seat is connected to the slide rail, and the first locking groove is disposed on the fixed seat. The direction of the first locking groove is perpendicular to the sliding direction of the slide rail, and one end of the first locking groove away from the slide rail is an open end, while the other end is a closed end.

[0008] In one embodiment, the second locking groove includes a first locking groove and a second locking groove. One end of the first locking groove is a closed end, and the other end is connected to the second locking groove. The direction of the second locking groove is perpendicular to the sliding direction of the slide rail, and the end of the second locking groove that is not connected to the first locking groove is an open end.

[0009] In one embodiment, the distance from the closed end to the open end of the first locking groove on the second locking groove to the slide rail gradually increases.

[0010] In one embodiment, the width of the second locking groove gradually increases from the closed end to the open end of the first locking groove, and the width of the first locking groove gradually increases from the closed end to the open end.

[0011] In one embodiment, an electronic control board is provided inside the chassis, and a fingerprint information processing chip is provided on the electronic control board.

[0012] In one embodiment, the chassis is provided with a distance sensor for detecting the distance between the outer shell and the top cover, and the distance sensor is communicatively connected to the electronic control board.

[0013] On the other hand, a method for switching a chassis is provided, the method comprising:

[0014] Upon receiving the user's fingerprint information and responding to the successful security verification of the fingerprint information, the motor assembly is activated to drive the slide rail to slide so that the first locking groove on the fixed base aligns with the second section of the second locking groove on the outer shell, thereby realizing the unlocking action;

[0015] The system receives distance information from a distance sensor. In response to the distance information being less than a distance threshold, the system activates the motor assembly to drive the slide rail to slide so that the first locking groove on the fixed base aligns with the first segment of the second locking groove on the housing, thereby achieving a locking action.

[0016] On another front, a server is provided, the server including a motherboard connected to an electronic control board, the electronic control board having a backup battery connected to it.

[0017] The technical solution described in this application has the following advantages over the prior art:

[0018] The aforementioned chassis, its control method, and server are connected by a fingerprint lock between the chassis's top cover and outer shell. When a user disassembles the top cover from the outer shell, they must first undergo security verification via the fingerprint recognition device of the fingerprint lock. After successful verification, the motor assembly is controlled to rotate, thereby causing the slide rail to slide. The sliding of the slide rail can switch the engagement state of the first and second locking slots, that is, switch between the locked and unlocked states, thus realizing the locking and unlocking of the top cover and the outer shell. This not only improves the security performance of the chassis but also increases disassembly efficiency, eliminating the need for manual disassembly of bolts and other components.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] Example 1

[0035] Reference Figures 1-10 As shown, the chassis includes an outer shell 1 and a top cover 2, with a fingerprint lock 3 connected between the outer shell 1 and the top cover 2. The fingerprint lock 3 includes a fingerprint recognition device 4 and a motor assembly 5 that are interconnected. A slide rail 6 is slidably connected inside the outer shell 1, and the output shaft of the motor assembly 5 is movably connected to the slide rail 6. A first locking groove 7 is provided on the slide rail 6, a second locking groove 8 is provided on the outer shell 1, and a locking rod 9 is provided on the top cover 2. The first locking groove 7, the second locking groove 8, and the locking rod 9 cooperate to control the unlocking or locking of the outer shell 1 and the top cover 2.

[0036] In existing technology, the outer shell 1 and the top cover 2 of a chassis are locked or unlocked using bolts or other structures. This structure has poor security performance. Therefore, this application proposes a chassis comprising an outer shell 1 and a top cover 2, connected by a fingerprint lock 3. This fingerprint lock 3 effectively improves the security performance of the chassis. Furthermore, the fingerprint lock 3 includes a fingerprint recognition device 4 and a motor assembly 5. The fingerprint recognition device 4 and the motor assembly 5 are communicatively connected. The fingerprint recognition device 4 identifies the user's fingerprint information for security verification. Once the fingerprint information is successfully verified, the fingerprint recognition device 4 triggers a signal, which is the start signal for the motor assembly 5. Upon receiving this start signal, the motor assembly 5 begins operation to control the sliding movement of the slide rail 6. The slide rail 6 is provided on the outer shell 1 and is located inside the outer shell 1. Figure 2 As shown, the slide rail 6 is slidably mounted inside the housing 1, and the output shaft of the motor assembly 5 is movably connected to the slide rail 6, converting the rotational motion of the motor assembly 5 into the sliding motion of the slide rail 6. Figure 2 As shown, the sliding direction of the slide rail 6 is horizontal. Specifically, one slide rail 6 is provided on each of the inner walls of both sides of the outer casing 1. A locking rod 9 is provided on the upper cover 2. The locking rod 9 cooperates with the locking groove to lock and unlock the outer casing 1 and the upper cover 2. The locking groove includes a first locking groove 7 and a second locking groove 8. The slide rail 6 has a first locking groove 7, and the outer casing 1 has a second locking groove 8. The first locking groove 7 and the second locking groove 8 cooperate with the locking rod 9 to lock and unlock the outer casing 1 and the upper cover 2. Figure 3 As shown in the locked state, when the first locking groove 7, the second locking groove 8, and the locking rod 9 are in the locked state, the first locking groove 7 restricts the movement of the locking rod 9 along the sliding direction of the slide rail 6, and the second locking groove 8 restricts the movement of the locking rod 9 along the sliding direction perpendicular to the slide rail 6. Therefore, the locking rod 9 is simultaneously constrained in the first locking groove 7 and the second locking groove 8. Since the upper cover 2 is connected to the locking rod 9, therefore... Figure 3 The locked state shown achieves the locking of the outer casing 1 and the upper cover 2; as... Figure 4 As shown in the unlocked state, when the first locking groove 7, the second locking groove 8, and the locking rod 9 are in the unlocked state, both the first locking groove 7 and the second locking groove 8 restrict the movement of the locking rod 9 along the sliding direction of the slide rail 6, but do not restrict the movement of the locking rod 9 in the direction perpendicular to the sliding direction of the slide rail 6. Therefore, the locking rod 9 can be lifted by the user in the direction perpendicular to the sliding direction of the slide rail 6. Figure 4 The unlocked state shown indicates that the outer casing 1 and the upper cover 2 are unlocked. The slide rail 6 is U-shaped, which reduces the weight of the slide rail 6 and facilitates the sliding movement of the slide rail 6 by the motor assembly 5.

[0037] The top cover 2 and the outer shell 1 of the chassis in this application are connected by a fingerprint lock 3. When the user disassembles the top cover 2 and the outer shell 1, the fingerprint recognition device 4 of the fingerprint lock 3 must be used for security verification. After the security verification is passed, the motor assembly 5 is controlled to rotate, thereby realizing the sliding of the slide rail 6. The sliding of the slide rail 6 can realize the switching of the engagement state of the first locking groove 7 and the second locking groove 8, that is, the switching of the locked state and the unlocked state, thereby realizing the locking and unlocking of the top cover 2 and the outer shell 1. This not only improves the security performance of the chassis, but also improves the disassembly efficiency, eliminating the need to manually disassemble bolts and other components.

[0038] In one embodiment, the motor assembly 5 is disposed inside the housing 1, and a gear 10 is connected to the output shaft of the motor assembly 5. The slide rail 6 is provided with a meshing hole 11 that meshes with the gear 10, and the gear 10 and the meshing hole 11 form a transmission mechanism.

[0039] like Figure 2 As shown, a slide rail 6 is installed on each side of the inner wall of the outer casing 1. The motor assembly 5 is located on the inner wall of the outer casing 1 near the slide rail 6. Preferably, each slide rail 6 is equipped with three motor assemblies 5. Specifically, Figure 2 The chassis is horizontal, and the two slide rails 6 installed inside are also horizontal. Since the rotation of the motor assembly 5 needs to be converted into the sliding motion of the slide rails 6, a transmission mechanism with gears 10 is selected, such as... Figure 3 As shown, a transmission block is provided on the output shaft of the motor assembly 5, and a transmission groove is formed in the middle of the gear 10 to cooperate with the transmission block. The transmission block and the transmission groove cooperate to realize the transmission connection between the output shaft of the motor assembly 5 and the gear 10, transmitting the rotational power of the output shaft of the motor assembly 5 to the gear 10. A meshing hole 11 is provided on the slide rail 6 at the part that cooperates with the gear 10. The transmission teeth on the gear 10 cooperate with the meshing hole 11 to form a transmission mechanism similar to a gear and rack pair. Through this transmission mechanism, the rotation of the gear 10 is converted into the sliding movement of the slide rail 6. Furthermore, three sets of transmission mechanisms are provided, that is, three sets of motor assemblies 5 and three sets of transmission mechanisms are provided respectively, so that the sliding power of the slide rail 6 is relatively stable.

[0040] In one embodiment, a fixed seat 12 is connected to the slide rail 6, and the first locking groove 7 is disposed on the fixed seat 12. The direction of the first locking groove 7 is perpendicular to the sliding direction of the slide rail 6, and one end of the first locking groove 7 away from the slide rail 6 is an open end, and the other end is a closed end.

[0041] like Figure 3 and Figure 8As shown, a fixed seat 12 is provided on the top of the slide rail 6, and a first locking groove 7 is provided on the fixed seat 12, located at the top center of the fixed seat 12. The first locking groove 7 extends from the top of the fixed seat 12 in a direction perpendicular to the sliding direction of the slide rail 6, that is, the direction of the first locking groove 7 is perpendicular to the sliding direction of the slide rail 6. The first locking groove 7 has two ends, one end being the end closer to the slide rail 6, which is a closed end; the other end being the end farther from the slide rail 6, which is an open end. The locking rod 9 on the outer shell 1 enters or disengages from the closed end of the first locking groove 7 through the open end, thereby cooperating with the second locking groove 8 to lock and unlock the upper cover 2 and the outer shell 1. Furthermore, the bottom of the mounting base 12 is provided with two connecting ears, each with a mounting hole. Bolts pass through the mounting holes and connect to the slide rail 6, thereby securing the mounting base 12 to the slide rail 6. Due to wear between the first locking groove 7 and the locking rod 9 on the mounting base 12, the mounting base 12 can be replaced according to its usage, improving the service life of the chassis. In addition, the two side walls of the first locking groove 7 on the mounting base 12 are rounded to the top sides of the mounting base 12, facilitating the sliding of the locking rod 9 within the first locking groove 7.

[0042] In one embodiment, the second locking groove 8 includes a first locking groove 13 and a second locking groove 14. One end of the first locking groove 13 is a closed end, and the other end is connected to the second locking groove 14. The direction of the second locking groove 14 is perpendicular to the sliding direction of the slide rail 6, and the end of the second locking groove 14 that is not connected to the first locking groove 13 is an open end.

[0043] like Figure 9 As shown, the second locking groove 8 includes a first locking groove 13 and a second locking groove 14, which are interconnected and connected by an arc transition. One end of the first locking groove 13 is a closed end, and the other end is connected to the second locking groove 14; the direction of the second locking groove 14 is perpendicular to the sliding direction of the slide rail 6, and the end of the second locking groove 14 that is not connected to the first locking groove 13 is an open end. In actual application, the locking rod 9 on the upper cover 2 moves along the trajectory of the second locking groove 8, moving from the open end of the second locking groove 14 to the closed end of the first locking groove 13, or from the closed end of the first locking groove 13 to the open end of the second locking groove 14. Further, as... Figure 3In the locked state shown, the first locking groove 7 slides perpendicularly to the slide rail 6, and the first segment of the second locking groove 8, 13, slides perpendicularly to the slide rail 6. The inner wall surface of the outer casing 1 where the second locking groove 8 is located is defined as a reference plane. The projections of the first locking groove 7 and the first segment of the second locking groove 8, 13, along the direction perpendicular to the reference plane intersect; this intersection is defined as an intersection groove, which is a closed groove. When the locking rod 9 is located in this closed groove, the closed groove restricts the movement of the locking rod 9 along the slide rail 6 and also restricts its movement perpendicular to the slide rail 6. Therefore, the locking rod 9 is constrained within the closed groove, achieving the locking action. Figure 4 In the unlocked state shown, the first locking groove 7 slides perpendicularly to the slide rail 6, and the second segment of the second locking groove 8, 14, slides perpendicularly to the slide rail 6, and the two are arranged parallel to each other. The projections of the first locking groove 7 and the second segment of the second locking groove 8, 14, perpendicular to the reference plane intersect; this intersection is defined as an intersection groove, which is an open groove. When the locking rod 9 is located in this open groove, the open groove only restricts the movement of the locking rod 9 along the slide rail 6, but does not restrict its movement perpendicular to the slide rail 6. Therefore, the locking rod 9 can be moved out by the user along the open groove, thus unlocking the device. Furthermore, the open ends of the second segment of the second locking groove 14 on the second locking groove 8 are chamfered or rounded to facilitate the sliding of the locking rod 9. Furthermore, the first locking groove 7 on the slide rail 6, the second locking groove 8 on the outer shell 1, and the locking rod 9 on the top cover 2 are used in conjunction. Preferably, four sets of the first locking groove 7 on each slide rail 6, the second locking groove 8 on the outer shell 1, and the locking rod 9 on the top cover 2 are provided to improve the locking stability and safety performance between the outer shell 1 and the top cover 2 of the chassis.

[0044] In one embodiment, the distance from the closed end to the open end of the first locking groove 13 on the second locking groove 8 to the slide rail 6 gradually increases.

[0045] like Figure 9 As shown, the distance from the closed end to the open end of the first section of the locking groove 13 on the second locking groove 8 to the slide rail 6 gradually increases, that is... Figure 9 The bottom surface of the first locking groove 13 is inclined upward from the closed end to the open end. When the locking rod 9 on the upper cover 2 moves along the first locking groove 7 from the closed end to the open end of the first locking groove 13, the locking rod 9 moves to the right and upward in the first locking groove 13. At this time, the upper cover 2 connected to the locking rod 9 moves to the right and upward under the action of the locking rod 9. A gap will be generated between the upper cover 2 and the outer shell 1. This gap makes it easy for the user to remove the upper cover 2 from the outer shell 1, which is convenient for disassembly. It also makes it easy for the user to see that the upper cover 2 and the outer shell 1 have been unlocked, making it more convenient to use.

[0046] In one embodiment, the width of the second locking groove 8 gradually increases from the closed end to the open end of the first locking groove 13, and the width of the first locking groove 7 gradually increases from the closed end to the open end.

[0047] like Figure 9 As shown, the width of the second locking groove 8 gradually increases from the closed end to the open end of the first locking groove 13, as... Figure 8 As shown, the width of the first locking groove 7 gradually increases from the closed end to the open end. When the gear 10 rotates clockwise, the slide rail 6 moves to the right, and the fixed seat 12 moves to the right under the drive of the slide rail 6. Under the constraint of the first locking groove 7 and the second locking groove 8, the locking rod 9 moves to the right along the first section of the locking groove 13 on the second locking groove 8. When the first locking groove 7 is aligned with the second section of the locking groove 14 on the second locking groove 8, the locking rod 9 can disengage from the first locking groove 7 and the second locking groove 8, realizing unlocking. The width of the second locking groove 8 gradually increases from the closed end to the open end of the first section of the locking groove 13, which facilitates the locking rod 9 to move out of the second locking groove 8. The width of the first locking groove 7 gradually increases from the closed end to the open end. The upper cover 2 gradually increases in size, making it easier for the user to remove it from the outer shell 1. When the gear 10 rotates counterclockwise, the slide rail 6 moves to the left, and the fixed seat 12 moves to the left under the drive of the slide rail 6. When the first locking groove 7 aligns with the first section of the locking groove 13 on the second locking groove 8, the locking rod 9 is constrained within the first locking groove 7 and the second locking groove 8, thus achieving locking. Conversely, the width of the groove in the second locking groove 8 gradually decreases from the open end to the closed end, and the width of the groove in the first locking groove 7 gradually decreases from the open end to the closed end, so that the locking rod 9 is gradually locked by the first locking groove 7 and the second locking groove 8, improving the stability of locking.

[0048] In one embodiment, an electronic control board 15 is provided inside the chassis, and a fingerprint information processing chip is provided on the electronic control board 15.

[0049] An electronic control board 15 is installed inside the chassis. The electronic control board 15 controls the locking and unlocking of the upper cover 2 and the outer shell 1 through the fingerprint lock 3. The electronic control board 15 is equipped with a fingerprint information processing chip, which is used to store the user's fingerprint information and perform security verification between the fingerprint information and the fingerprint information database to determine whether the fingerprint information is recorded in the fingerprint information database. If the fingerprint information is in the fingerprint information database, the motor assembly 5 is activated to unlock; if the fingerprint information is not in the fingerprint information database, the unlocking fails.

[0050] In one embodiment, a distance sensor 16 for detecting the distance between the outer casing 1 and the upper cover 2 is provided inside the chassis, and the distance sensor 16 is communicatively connected to the electronic control board 15.

[0051] A distance sensor 16, which can be an infrared sensor, is installed inside the chassis to measure the distance between the outer shell 1 and the upper cover 2. If the distance between the outer shell 1 and the upper cover 2 is within a distance threshold, it indicates that the upper cover 2 is in place, and the motor assembly 5 can be activated to lock the upper cover 2 and the outer shell 1. If the distance between the outer shell 1 and the upper cover 2 is outside the distance threshold, it indicates that the upper cover 2 is not in place, and the motor assembly 5 will be activated after the user places the upper cover 2 in place to lock the upper cover 2 and the outer shell 1. Furthermore, four infrared sensors are installed at both ends of each slide rail 6. The motor assembly 5 will only be activated to lock the upper cover 2 and the outer shell 1 when all four infrared sensors detect a distance less than the distance threshold.

[0052] In one embodiment, the slide rail 6 is provided with a limiting groove 19, and the outer shell 1 is provided with a limiting pin 20 that cooperates with the limiting groove 19, the limiting pin 20 passing through the limiting groove 19.

[0053] When the motor assembly 5 controls the slide rail 6 to slide, it is necessary to control the moving distance of the slide rail 6. The moving distance of the slide rail 6 must match the moving distance of the locking rod 9 in the second locking groove 8. For example... Figure 3 As shown, when the motor assembly 5 rotates clockwise, causing the slide rail 6 to slide to the right, the locking rod 9 must move until it aligns with the second section of the locking groove 14 on the first locking groove 7 and the second locking groove 8 to unlock. When the motor assembly 5 rotates counterclockwise, causing the slide rail 6 to slide to the left, the locking rod 9 must move until it aligns with the first section of the locking groove 13 on the first locking groove 7 and the second locking groove 8 to unlock. Therefore, the position of the locking rod 9 when it is at the closed end of the first section of the locking groove 13 on the second locking groove 8 is defined as the first position, and the position of the locking rod 9 when it is inside the second section of the locking groove 14 on the second locking groove 8 is defined as the second position. The distance between the axis of the locking rod 9 at the first position and the axis of the locking rod 9 at the second position is the sliding distance of the slide rail 6. Therefore, as shown... Figure 3 The limiting groove 19 shown has a limiting pin 20 on the outer shell 1 inserted into it. The diameter of the limiting pin 20 is slightly smaller than the width of the limiting groove 19. The distance between the centers of the two ends of the limiting groove 19 matches the sliding distance of the slide rail 6, thereby limiting the sliding of the slide rail 6 and effectively locking and unlocking the upper cover 2 and the outer shell 1. Alternatively, if the sliding distance of the slide rail 6 is not limited by the limiting groove 19, it can be converted into the rotation angle of the output shaft on the motor assembly 5, which is equivalent to controlling the rotation angle of the gear 10 shaft, thereby indirectly controlling the sliding distance of the slide rail 6.

[0054] Example 2

[0055] Reference Figure 11 As shown, Figure 11 This is a schematic diagram of a chassis switching method provided in an embodiment of this application.

[0056] A method for switching the aforementioned chassis is provided, the method comprising:

[0057] Upon receiving the user's fingerprint information and responding to the successful security verification of the fingerprint information, the motor assembly 5 is activated to drive the slide rail 6 to slide so that the first locking groove 7 on the fixed base 12 is aligned with the second locking groove 14 of the second locking groove 8 on the outer shell 1, thereby realizing the unlocking action.

[0058] When a user needs to remove the top cover 2 from the outer casing 1, the user touches the fingerprint recognition device 4 with their corresponding finger, and the fingerprint recognition device 4 collects the user's fingerprint information. After receiving the user's fingerprint information, the fingerprint recognition device 4 compares the user's fingerprint information with the fingerprint information database to determine whether the received fingerprint information exists in the fingerprint information database. If the received fingerprint information is not in the fingerprint information database, a fingerprint recognition failure message is displayed, and the unlocking action will not be performed. If the received fingerprint information is in the fingerprint information database, it means that the user has the right to disassemble the chassis, and the security verification is successful. After successful security verification, the fingerprint recognition device 4 sends a start signal to the motor assembly 5. Upon receiving the start signal, the motor assembly 5 starts and rotates clockwise. The output shaft of the motor assembly 5 drives the gear 10 to rotate clockwise, which in turn drives the slide rail 6 to move to the right. The slide rail 6 then drives the fixed seat 12 to move to the right. The fixed seat 12, through the first locking groove 7, drives the locking rod 9 to move along the second locking groove 8, so that the locking rod 9 moves from the closed end of the first locking groove 13 on the second locking groove 8 to the open end of the second locking groove 14 on the second locking groove 8. Finally, the first locking groove 7 and the second locking groove on the second locking groove 8 are aligned. At this time, the locking rod 9 is in the unlocked state in the first locking groove 7 and the second locking groove 8. Therefore, the top cover 2 connected to the locking rod 9 is in the unlocked state, and the user can remove the top cover 2 from the outer shell 1.

[0059] Upon receiving distance information from distance sensor 16, and in response to the distance information being less than a distance threshold, the motor assembly 5 is activated to drive the slide rail 6 to slide so that the first locking groove 7 on the fixed base 12 aligns with the first segment locking groove 13 of the second locking groove 8 on the outer shell 1, thereby achieving a locking action.

[0060] The distance sensor 16 collects the distance between the top cover 2 and the outer shell 1. After receiving the distance information from the distance sensor 16, the distance information is compared with a distance threshold to determine whether the distance information is within the distance threshold. If the distance information is not within the distance threshold, it means that the user operation has not been completed and the locking action cannot be performed. If the distance information is within the distance threshold, it means that the user operation has been completed and the user has placed the top cover 2 on the outer shell 1. After the user places the top cover 2 on the outer shell 1, a start signal is sent to the motor assembly 5. After receiving the start signal, the motor assembly 5 starts and rotates counterclockwise. The output shaft of the motor assembly 5 drives the gear 10 to rotate counterclockwise. The gear 10 drives the slide rail 6 to move to the left. The slide rail 6 drives the fixed seat 12 to move to the left. The fixed seat 12 drives the locking rod 9 to move along the second locking groove 8 through the first locking groove 7, so that the locking rod 9 moves from the second locking groove 8 to the second segment. The open end of the locking groove 14 moves to the closed end of the first locking groove 13 on the second locking groove 8, so that the first locking groove 7 is aligned with the first locking groove 13 on the second locking groove 8. At this time, the locking rod 9 is in a locked state in the first locking groove 7 and the second locking groove 8. The first locking groove 7 restricts the movement of the locking rod 9 along the sliding direction of the slide rail 6, and the second locking groove 8 restricts the movement along the sliding direction perpendicular to the slide rail 6. Therefore, the upper cover 2 connected to the locking rod 9 is in a locked state, realizing automatic locking.

[0061] Example 3

[0062] Among the servers using the aforementioned chassis, and Figures 1-10 For identical or similar content in the structural diagram shown, please refer to... Figures 1-10 The structure of the text will not be elaborated here.

[0063] A server including the aforementioned chassis is provided.

[0064] The server includes a motherboard 17, an electronic control board 15 connected to the motherboard 17, and a backup battery 18 connected to the electronic control board 15.

[0065] The server includes a motherboard 17, and an electronic control board 15 is connected to the motherboard 17, so the motherboard 17 can supply power to the electronic control board 15. When the server loses power, the electronic control board 15 is powered by a backup battery 18, allowing the chassis to still be switched on and off. Furthermore, if the server loses power and the backup battery 18 is depleted, the motor assembly 5 is configured to rotate counter-clockwise only under external force when it is powered off. This means that when the motor assembly 5 is powered off, the user can only manually push the top cover 2, causing the locking rod 9 of the top cover 2 to move from the open end of the second locking groove 14 on the second locking groove 8 to the closed end of the second locking groove 14. This only locks the top cover 2 to the outer casing 1, preventing unlocking and effectively improving the server's security.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
