Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a top cover assembly and a server. Background Art

[0002] As the computing and storage density of servers increases, the weight and overall length of servers continue to increase, placing increasing demands on the structural rigidity of the chassis. Existing technologies often restrict the position of the chassis cover and base by riveting multiple pegs to the server cover, which mate with the limiting notches on the base. However, to facilitate disassembly between the cover and base, the pegs can only partially restrict the cover's freedom. Due to insufficient constraints between the cover and base, the server is prone to excessive torsional deformation during transportation and cabinet installation, which can cause abnormal stress on the server's internal motherboard and electronic components, increasing the risk of failure. Summary of the Invention

[0003] This application provides a top cover assembly and a server. The top cover assembly includes a top cover and a top cover lock. The top cover lock is fixed to the top cover and includes a pin. When the pin is extended, the pin securely connects the top cover to the base, thereby locking the top cover and the base. When the pin is retracted, the top cover and the base are unlocked. The pin allows the top cover to form a stable connection with the base. This top cover assembly can significantly improve the torsional rigidity of the entire server structure.

[0004] In a first aspect, the present application provides a cover assembly for use with a server, the cover assembly being mounted on a base of the server. The cover assembly includes a cover and a cover lock secured to the cover. The cover lock includes a pin. When the cover lock is locked, the pin is extended to engage the base; when the cover lock is unlocked, the pin is retracted.

[0005] In this application, when the cover lock is in the locked state, the pin extends to engage the base, and the pin securely connects the cover and base, thereby locking the cover and base. When the cover lock is unlocked, the pin retracts, unlocking the cover and base. The pin provides a stable connection between the cover and the base, significantly improving the torsional rigidity of the server structure.

[0006] In some possible implementations, the upper cover includes a top plate and a first side plate connected thereto, the base includes a bottom plate and a second side plate connected thereto, and the pin is insertable into the first side plate of the upper cover. When the upper cover lock is in a locked state, the pin extends relative to the first side plate of the upper cover to insert into the second side plate of the base; when the upper cover lock is in an unlocked state, the pin retracts relative to the first side plate of the upper cover.

[0007] In this application, the upper cover is mounted on the base, with the first side panel of the upper cover facing the second side panel of the base. When the upper cover is locked, the pin extends from the first side panel of the upper cover to engage with the second side panel of the base. That is, the pin engages the first side panel of the upper cover with the second side panel of the base, forming a stable connection between the upper cover and the base. Furthermore, the first side panel of the upper cover is fixedly connected to the second side panel of the base, and the mutual coordination between the two helps to improve the structural strength of the server side panel.

[0008] In some possible implementations, the upper cover lock further includes a base, a wrench, a rotating shaft, a crank, a connecting rod, and an elastic member. The base is fixed to the top plate of the upper cover, the wrench is rotatably connected to the base, and the rotating shaft is plugged into the wrench. When the wrench rotates relative to the base, the rotating shaft moves relative to the base between a first position and a second position. The crank is rotatably connected to the base, one end of the crank is rotatably connected to the first end of the connecting rod, and the pin is rotatably connected to the second end of the connecting rod. The elastic member connects the crank, pin, or connecting rod, and the elastic member is used to generate an elastic force. When the upper cover lock is in a locked state, the wrench is closed relative to the base, the rotating shaft is in the first position and abuts against the other end of the crank, and the pin extends relative to the first side plate of the upper cover to plug into the second side plate of the base; when the upper cover lock is in an unlocked state, the wrench is opened relative to the base, the rotating shaft is in the second position and disengaged from the crank, and the pin retracts relative to the first side plate of the upper cover under the elastic force.

[0009] In this application, the upper cover lock is used to control the locking and unlocking of the upper cover and the base. Compared with the upper cover lock of the server with a complex structure in the prior art, this embodiment only requires turning a wrench to cause the rotating shaft to rotate the crank, and the crank drives the connecting rod to move toward the first side plate of the upper cover. When the elastic member is compressed, the pin extends relative to the first side plate of the upper cover to plug into the second side plate of the base, thereby fixing the upper cover and the base and quickly locking the upper cover and the base. When the rotating shaft is disengaged from the crank, the pin automatically retracts relative to the first side plate of the upper cover under the action of the elastic member, and the upper cover and the base are quickly unlocked. This upper cover lock has a simple structure, and the upper cover assembly using this upper cover lock is easy to assemble and disassemble with the base, which helps to reduce the cost of the server and improve the user experience.

[0010] In some possible implementations, the wrench includes a rotating part, a handle part connected to the rotating part, and a plug-in part. The rotating part rotates and connects to the base, the rotating shaft is inserted into the plug-in part, and the distance between the handle part and the rotating part is greater than the distance between the plug-in part and the rotating part.

[0011] In this application, the rotating portion is located between the handle portion and the plug portion, so that the handle portion and the plug portion can rotate around the rotating portion. The distance between the handle portion and the rotating portion is greater than the distance between the plug portion and the rotating portion, so that the user can easily rotate the wrench, thereby improving the user experience.

[0012] In some possible implementations, the wrench rotates relative to the base around a first rotation center, and the crank rotates relative to the base around a second rotation center, where the second rotation center is not parallel to the first rotation center.

[0013] In this application, the design of the crank's first end, middle portion, and second end can alter the rotational motion. The wrench rotates about the first rotational center, and the shaft pushes the crank to rotate about the middle portion, thereby converting the rotational motion into rotation of the crank about the second rotational center. The crank's coordination with the connecting rod allows the crank to transmit force and displacement to a pin located away from the base through the connecting rod. The connecting rod converts the crank's rotation into movement of the pin, allowing the pin to extend relative to and be inserted into the first side panel of the upper cover.

[0014] In some possible implementations, the base includes a base body and a bracket, the bracket is located on one side of the base body, the base body has an installation space, the wrench is installed in the installation space, and the crank rotates to connect the bracket.

[0015] In some possible implementations, one end of the elastic member is fixed to the crank, and the other end of the elastic member is fixed to the bracket. When the rotating shaft abuts the crank, the elastic member generates an elastic force. When the rotating shaft disengages from the crank, the crank rotates relative to the bracket under the elastic force, driving the connecting rod toward the base, causing the pin to retract relative to the first side plate of the upper cover.

[0016] In the present application, the crank can be automatically retracted under the action of the elastic member without applying external force, and the unlocking operation of the upper cover assembly is simpler.

[0017] In some possible implementations, the crank includes a middle portion and a first end and a second end connected to the middle portion. The middle portion is rotatably connected to the bracket via a first connecting member. The first end is rotatably connected to the first end of the connecting rod. The second end is configured to abut the rotating shaft when the rotating shaft is in the first position. The elastic member is a torsion spring, which is mounted on the first connecting member and fixedly connects the middle portion and the bracket.

[0018] In this application, when the rotating shaft abuts the crank, the second end of the crank rotates away from the base, causing the elastic member to be stretched, generating an elastic force. When the rotating shaft disengages from the crank, the abutment on the crank by the rotating shaft is removed, and the connecting rod and the pin are free. The elastic force of the elastic member causes the second end of the crank to rotate toward the base, causing the pin to retract relative to the first side plate of the upper cover, thereby unlocking the upper cover assembly. Under the action of the elastic member, the crank automatically retracts without the application of external force, making the unlocking operation of the upper cover assembly simpler.

[0019] In some possible implementations, the upper cover lock further includes a support secured to the upper cover, a pin inserted into the support, and an elastic member positioned between the support and the pin. When the rotating shaft abuts the crank, the elastic member is compressed, generating an elastic force. When the rotating shaft disengages the crank, the pin retracts relative to the first side plate of the upper cover under the elastic force.

[0020] In this application, simply by turning a wrench, the rotating shaft pushes the crank to rotate, and the crank drives the connecting rod to move toward the first side plate of the upper cover. As the elastic member is compressed, the pin extends relative to the first side plate of the upper cover, thereby fixing the upper cover and the base, and the upper cover and the base are quickly locked. When the rotating shaft is disengaged from the crank, the pin automatically retracts relative to the first side plate of the upper cover under the action of the elastic member, and the upper cover and the base are quickly unlocked. This upper cover lock has a simple structure, and the upper cover assembly using this upper cover lock is easy to assemble and disassemble with the base, which helps reduce server costs and improve user experience.

[0021] In some possible implementations, the upper cover lock further includes a locking block, which is mounted on the base and is used to lock the base.

[0022] In the present application, the locking block is used to lock the base, so that the locking block is fixed relative to the base.

[0023] In some possible implementations, the base includes a base body, the base body including a first side wall, a second side wall, and a bottom wall, the first side wall and the second side wall being arranged opposite each other, the bottom wall being connected between the first side wall and the second side wall, the wrench being mounted between the first side wall and the second side wall, the locking block being located between the wrench and the bottom wall, the locking block being slidably connected to the first side wall and the second side wall, the first side wall being provided with a first slide groove, the locking block being provided with a mounting groove, the mounting groove extending along a trajectory different from that of the first slide groove, and the rotating shaft being provided through the first slide groove and the mounting groove. When the wrench rotates relative to the base, the rotating shaft moves within the first slide groove and the mounting groove, and the base moves relative to the locking block.

[0024] In the present application, when the plug-in part of the wrench rotates around the rotating part, the rotating shaft needs to move simultaneously in the mounting groove of the locking block and the first slide groove and the second slide groove of the seat body. Since the locking block and the seat body can slide relative to each other, and the extension trajectory of the mounting groove is different from the extension trajectory of the first slide groove and the second slide groove, the rotating shaft can push the locking block and the seat body to slide relative to each other when rotating.

[0025] In some possible implementations, the upper cover lock further includes a snap-fitting seat, which is fixed to the base, and the locking block is snap-fitted to the snap-fitting seat.

[0026] In this application, the engaging seat is fixed to the base, and the engaging block engages the positioning post of the engaging seat, thereby securing the engaging block relative to the base. The base body is fixed to the upper cover, thereby securing the base body relative to the upper cover. When the wrench rotates relative to the base body, it drives the rotating shaft to slide simultaneously within the first slide groove, the second slide groove, and the mounting groove. Because the extension trajectory of the mounting groove differs from that of the first and second slide grooves, the engaging block and the base body slide relative to each other, further driving the base and the upper cover to slide relative to each other.

[0027] In some possible implementations, the crank, connecting rod, pin and elastic member constitute a first latch assembly, and the upper cover lock also includes a second latch assembly. The second latch assembly and the first latch assembly are symmetrical structures, and the rotating shaft is also used to support the crank of the second latch assembly when the wrench is closed relative to the base.

[0028] In this embodiment, the pins of the first and second latch assemblies are respectively inserted into the upper cover and the base. Specifically, the first latch assembly securely connects the first side panel on one side of the upper cover to the second side panel on the corresponding side of the base, while the second latch assembly securely connects the first side panel on the other side of the upper cover to the second side panel on the other side of the base. This ensures that the first side panels on both sides of the upper cover and the second side panels on both sides of the base are constrained and fixed. Compared to single-sided constrained fixation, double-sided constrained fixation significantly improves the torsional rigidity of the server. Furthermore, the upper cover lock has a simple structure and is easy to operate, enabling rapid assembly and disassembly of the upper cover assembly.

[0029] In a second aspect, the present application further provides a server, which includes any of the upper cover components described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a portion of the structure of the server 1000 provided in some embodiments of the present application. Figure 2 yes Figure 1 A schematic diagram of a partially exploded structure of the server 1000 is shown.

[0062] In some embodiments, the present application provides a server 1000. Server 1000 is a high-performance computer on a network that provides various services to client computers. Under the control of a network operating system, it shares connected data storage devices, tapes, printers, and various specialized communication devices with client sites on the network. It also provides network users with centralized computing, information publishing, and data management services. Its high performance is primarily reflected in its high-speed computing capabilities, long-term reliable operation, and strong external data throughput.

[0063] In some embodiments, the server 1000 may include a cover assembly 100 and a base 200, wherein the cover assembly 100 is mounted on the base 200. The cover assembly 100 may include a cover 20 and a cover lock 10, wherein the cover lock 10 is fixed to the cover 20. The cover lock 20 may include a pin 7. The cover lock 10 has a locked state and an unlocked state. When the cover lock 10 is in the locked state, the pin 7 is extended to engage with the base 200, and the cover 20 is fixed to the base 200. When the cover lock 10 is in the unlocked state, the pin 7 is retracted, and the cover 20 can move relative to the base 200.

[0064] In this application, when the cover lock 10 is locked, the pin 7 extends to engage the base 200, securely connecting the cover 20 and the base 200, thereby locking the cover 20 and the base 200. When the cover lock 10 is unlocked, the pin 7 retracts, unlocking the cover 20 and the base 200. The pin 7 allows the cover 20 to form a stable connection with the base 200, significantly improving the torsional rigidity of the server 1000.

[0065] In some embodiments, the upper cover 20 may include a top plate 201 and a first side plate 202 connected to the top plate 201. The base 200 may include a bottom plate 2001 and a second side plate 2002 connected to the bottom plate 2001. The upper cover 20 is mounted on the base 200, with the first side plate 202 of the upper cover 20 and the second side plate 2002 of the base 200 disposed opposite each other. The first side plate 202 of the upper cover 20 and the second side plate 2002 of the base 200 together form a side plate of the server 1000. A pin 7 is insertable into the first side plate 202 of the upper cover 20. When the upper cover lock 10 is locked, the pin 7 extends relative to the first side plate 202 of the upper cover 20 to engage with the second side plate 2002 of the base 200. When the upper cover lock 10 is unlocked, the pin 7 retracts relative to the first side plate 202 of the upper cover 20.

[0066] In the present application, the upper cover 20 is mounted on the base 200, with the first side panel 202 of the upper cover 20 and the second side panel 2002 of the base 200 disposed opposite each other. When the upper cover lock 10 is in the locked state, the pin 7 extends from the first side panel 202 of the upper cover 20 to engage with the second side panel 2002 of the base 200. That is, the pin 7 engages the first side panel 202 of the upper cover 20 and the second side panel 2002 of the base 200, forming a stable connection between the upper cover 20 and the base 200. Furthermore, the first side panel 202 of the upper cover 20 and the second side panel 2002 of the base 200 are fixedly connected, and the mutual coordination between the two facilitates improving the structural strength of the side panels of the server 1000.

[0067] In some other embodiments, the pin 7 is inserted into other positions of the upper cover 20 and the base 200 to form a stable connection between the upper cover 20 and the base 200, which is not strictly limited in this application.

[0068] In some embodiments, the second side panel 2002 of the base 200 is provided with a plurality of limiting notches 2003, and the plurality of limiting notches 2003 are arranged at intervals. The first side panel 202 of the upper cover 20 can also be riveted with a plurality of hanging nails (not shown in the figure), and the plurality of hanging nails can be installed one by one in the plurality of limiting notches 2003, thereby limiting the first side panel 202 of the upper cover 20 and the second side panel 2002 of the base 200.

[0069] In the embodiment of the present application, the "first direction", "second direction" and "third direction" of the server 1000 are descriptions of relative directions, wherein the server 1000 can be roughly a rectangular parallelepiped, and the rectangular parallelepiped of the server 1000 includes three faces that are approximately perpendicular to each other, with the direction parallel to one of the faces of the rectangular parallelepiped of the server 1000 being the first direction, the direction parallel to another face of the rectangular parallelepiped of the server 1000 being the second direction, and the direction parallel to the third face of the rectangular parallelepiped of the server 1000 being the third direction.

[0070] Please refer to Figures 2 to 4 , Figure 3 yes Figure 2 The structure of the cover lock 10 in some embodiments is shown. Figure 4 yes Figure 3 The illustrated diagram is a partially exploded structural diagram of the cover lock 10 in some embodiments.

[0071] In some embodiments, the upper cover lock 10 may include a base 1, a wrench 2, a blocking block 3, a rotating shaft 4, a crank 5, a connecting rod 6, an elastic member 8, and a support 9. The base 1 is used to be fixed to the top plate 201 of the upper cover 20, and the wrench 2 is used to be rotatably connected to the base 1. The rotating shaft 4 is used to insert the wrench 2. When the wrench 2 rotates relative to the base 1, the rotating shaft 4 moves between a first position and a second position relative to the base 1, and the rotating shaft 4 can support the crank 5. The blocking block 3 is used to be slidably connected to the base 1, the crank 5 is rotatably connected to the base 1, the first end of the connecting rod 6 is rotatably connected to one end of the crank 5, and the pin 7 is rotatably connected to the second end of the connecting rod 6. The pin 7 is inserted into the support 9, and the support 9 is fixed to the upper cover 20. When the upper cover lock 10 is in the locked state, the wrench 2 is closed relative to the base 1, the rotating shaft 4 is located in the first position 118 and abuts the other end of the crank 5, and the pin 7 extends relative to the first side plate 202 of the upper cover 20 to plug into the second side plate 2002 of the base 200. When the upper cover lock 10 is in the unlocked state, the wrench 2 is opened relative to the base 1, the rotating shaft 4 is located in the second position and disengaged from the crank 5, and the pin 7 retracts relative to the first side plate 202 of the upper cover 20 under the elastic force. The base 1 may include a base body 11 and a bracket 12, and the bracket 12 is located on one side of the base body 11. Among them, abutment refers to the mutual contact between the rotating shaft 4 and the crank 5, and the existence of an interaction force between the rotating shaft 4 and the crank 5. In the relevant description below, abutment is understood similarly, referring to the mutual contact between two components and the existence of an interaction force between the two, and will not be repeated here.

[0072] In this embodiment, the cover lock 10 controls the locking and unlocking of the cover 20 and the base 200. Compared to the complex cover locks of conventional servers, in this embodiment, simply by turning the wrench 2, the shaft 4 rotates the crank 5, which drives the connecting rod 6 toward the first side plate 202 of the cover 20. The elastic member 8 is compressed, causing the pin 7 to extend relative to the first side plate 202 of the cover 20 to engage the second side plate 2002 of the base 200, thereby securely connecting the cover 20 and the base 200 and quickly locking the cover 20 and the base 200. When the shaft 4 disengages the crank 5, the pin 7, under the action of the elastic member 8, automatically retracts relative to the first side plate 202 of the cover 20, quickly unlocking the cover 20 and the base 200. This simple structure makes the cover lock 10 easy to assemble and disassemble from the base 200, thereby reducing the cost of the server 1000 and improving the user experience.

[0073] In some other embodiments, the upper cover lock 10 may also control the extension and retraction of the pin 7 in other ways so that the pin 7 can be plugged into the upper cover 20 and the base 200. This application does not impose strict limitations on this.

[0074] Please refer to Figure 1 、 Figure 2 and Figure 4 In some embodiments, the top plate 201 of the upper cover 20 may have a recessed groove 2011 and a first through-hole 2012. The opening of the recessed groove 2011 faces away from the base 200. The first through-hole 2012 is located at the bottom of the recessed groove 2011 and communicates with the recessed groove 2011. The base 11 is fixed to the top plate 201 of the upper cover 20, with the base 11 at least partially located within the recessed groove 2011 and the first through-hole 2012. The base 11 may include a top wall 111 having a plurality of first positioning holes 1112 defined therein, the plurality of first positioning holes 1112 being spaced apart. The recessed groove 2011 is provided with a plurality of first posts 2013, which are mounted in the first positioning holes 1112. In the embodiments of the present application, the "top" and "bottom" orientations of the various structures of the server 1000 are relative descriptions, wherein the direction from the base 200 to the upper cover 20 is the "bottom" to "top" direction. For example, the base 200 is located on the bottom side of the upper cover 20 .

[0075] In this embodiment, the first positioning hole 1112 of the base 11 cooperates with the first post 2013 of the upper cover 20. The first post 2013 serves to position and / or secure the base 11 during assembly with the upper cover 20. Furthermore, the upper cover 20 is provided with a recessed groove 2011, with the base 11 at least partially positioned within the recessed groove 2011 and the first through-hole 2012. This results in a relatively thin overall thickness for the upper cover assembly 100, preventing the base 11 from protruding relative to the upper cover 20. Furthermore, the recessed groove 2011 and the first through-hole 2012 also serve to position and / or limit the base 11, thereby reducing the difficulty of assembling the base 11.

[0076] Please refer to Figures 5A to 7 , Figure 5A yes Figure 4 The structure diagram of the seat body 11 in some embodiments is shown. Figure 5B yes Figure 5A The schematic structural diagram of the seat body 11 at another angle is shown. Figure 6 yes Figure 4 The schematic diagram of the structure of the positioning block 3 in some embodiments is shown. Figure 7 yes Figure 3 The partial structure diagram of the cover lock 10 in some embodiments is shown as follows: Figure 1 .

[0077] In some embodiments, the base body 11 may further include a first side wall 112, a second side wall 113, a bottom wall 114, a third side wall 115, and a fourth side wall 116. The first side wall 112 is disposed opposite the second side wall 113, the bottom wall 114 is disposed opposite the top wall 111, and the bottom wall 114 is connected between the first side wall 112 and the second side wall 113. The third side wall 115 is located between the top wall 111 and the bottom wall 114. The fourth side wall 116 is disposed opposite the third side wall 115, and the third side wall 115 connects the first side wall 112, the second side wall 113, and the top wall 111. The fourth side wall 116 connects the first side wall 112, the second side wall 113, the bottom wall 114, and the top wall 111. The first side wall 112, the second side wall 113, the bottom wall 114, the third side wall 115 and the fourth side wall 116 together form an installation space 117 of the base body 11. The fourth side wall 116 can be an arc-shaped wall protruding away from the third side wall 115. The volume of the installation space 117 increases near the fourth side wall 116. The installation space 117 extends along the second direction Y and can be used to install the wrench 2 and the positioning block 3. The base body 11 can be an integrated structural component. In this embodiment, please refer to Figure 4 , X direction is the first direction, Y direction is the second direction, and Z direction is the third direction. In the relevant description below, the relative positions of the first direction, the second direction and the third direction are understood similarly and will not be repeated here.

[0078] In some embodiments, the first side wall 112 is provided with a plurality of first protrusions 1121. The plurality of first protrusions 1121 are spaced apart and protrude toward the second side wall 113. Gaps are left between the plurality of first protrusions 1121 and the bottom wall 114. The locking block 3 is mounted on the base 11. Exemplarily, the locking block 3 is located between the bottom wall 114 and the first protrusions 1121. The locking block 3 slidably connects the first side wall 112 and the second side wall 113.

[0079] In this embodiment, the locking block 3 is slidably connected to the base 11, so that the base 11 can move relative to the locking block 3. The locking block 3 is located between the bottom wall 114 and the first protrusion 1121. The first protrusion 1121 limits the locking block 3 in the third direction Z to prevent the locking block 3 from separating from the base 11.

[0080] Alternatively, first side wall 112 is provided with a plurality of first protrusions 1121, and second side wall 113 is provided with a plurality of second protrusions 1131. Second protrusions 1131 are spaced apart and protrude toward first side wall 112, with gaps remaining between second protrusions 1131 and bottom wall 114. A locking block 3 is positioned between bottom wall 114 and first and second protrusions 1121, 1131, and slidably connects first and second side walls 112, 113.

[0081] In some embodiments, a first slot 1122 is provided at one end of the first sidewall 112 proximate to the third sidewall 115, and a second slot 1132 is provided at one end of the second sidewall 113 proximate to the third sidewall 115. The first slot 1122 and the second slot 1132 are disposed opposite each other. For example, the first slot 1122 and the second slot 1132 can both be arc-shaped slots, meaning that the first slot 1122 and the second slot 1132 extend in an arc-shaped pattern that curves away from the bottom wall 114. In other embodiments, the first slot 1122 and the second slot 1132 can also have other shapes. The first slot 1122 and the second slot 1132 are used to pass through the rotating shaft 4. The first sidewall 112 also has a first mounting hole 1123 located at the end of the first sidewall 112 proximate to the third sidewall 115, and spaced apart from the first slot 1122. The second side wall 113 is further provided with a second mounting hole 1133, which is disposed opposite to the first mounting hole 1123. The first mounting hole 1123 and the second mounting hole 1133 may be circular holes.

[0082] In some embodiments, the bottom wall 114 is spaced apart from the third side wall 115, and a third mounting hole 1141 is formed between the bottom wall 114 and the third side wall 115. A fourth mounting hole 1142 is defined at one end of the bottom wall 114 near the fourth side wall 116. For example, the fourth mounting hole 1142 can be generally a strip-shaped hole extending along the second direction Y.

[0083] In some embodiments, the locking block 3 may include a mounting portion 31, a sliding portion 32, and a positioning portion 33. The sliding portion 32 connects the mounting portion 31 and the positioning portion 33. The thickness of the mounting portion 31 in the third direction Z is greater than the thickness of the sliding portion 32 and the positioning portion 33 in the third direction Z. The mounting portion 31 is at least partially located in the third mounting hole 1141 of the base 11. The mounting portion 31 is provided with a mounting groove 311. The extension trajectory of the mounting groove 311 is different from the extension trajectory of the first slide groove 1122 and the second slide groove 1132. For example, the mounting groove 311 may be a strip-shaped groove, and the extension trajectory may be a straight line. The mounting groove 311 may extend generally along the third direction Z. In other embodiments, the mounting groove 311 may also have other shapes. The mounting groove 311 is used to pass through the rotating shaft 4. The positioning portion 33 is provided with a snap-fitting hole 331, and the positioning portion 33 is used to snap-fit to the base 200. The locking block 3 may be an integrated structural component.

[0084] Please refer to Figure 5A 、 Figures 8 to 10 , Figure 8 yes Figure 4 The structure diagram of the wrench 2 shown in some embodiments is as follows, Figure 9 yes Figure 3 The partial structure diagram of the cover lock 10 in some embodiments is shown as follows: Figure 2 , Figure 10 yes Figure 9 The illustrated schematic diagram is a cross-sectional structural diagram of the cover lock 10 along line AA in some embodiments.

[0085] In some embodiments, the wrench 2 is installed in the installation space 117 of the base 11. For example, the wrench 2 is installed between the first side wall 112 and the second side wall 113. The blocking block 3 is located between the wrench 2 and the bottom wall 114. The wrench 2 may include a rotating portion 21, a handle portion 22 connected to the rotating portion 21, and a plug-in portion 23. The rotating portion 21 is rotatably connected to the base 11, and the distance between the handle portion 22 and the rotating portion 21 is greater than the distance between the plug-in portion 23 and the rotating portion 21. The rotating portion 21 may be provided with a first rotating column 211 and a second rotating column 212, and the first rotating column 211 and the second rotating column 212 are arranged opposite to each other. The first rotating column 211 is installed in the first mounting hole 1123 of the base 11, and the second rotating column 212 is installed in the second mounting hole 1133 of the base 11, so that the wrench 2 is rotatably connected to the base 11. The rotating portion 21 and the plug-in portion 23 are located on the cantilever of the wrench 2. The wrench 2 also includes a first cantilever 24 and a second cantilever 25, which are spaced apart and arranged opposite each other. The first cantilever 24 and the second cantilever 25 are connected to the handle portion 22. The first rotating column 211 and the second rotating column 212 are respectively fixed to the first cantilever 24 and the second cantilever 25. The mounting portion 31 of the locking block 3 is located between the first cantilever 24 and the second cantilever 25. A gap is left between the handle portion 22 and the fourth side wall 116 of the base 11. The fourth side wall 116 protrudes outward toward the side away from the handle portion 22, making it easier for the user to remove the handle portion 22 from the base 11.

[0086] In this embodiment, the wrench 2 is rotatably connected to the first side wall 112 and the second side wall 113 of the base 11, making the connection between the wrench 2 and the base 11 more stable. In addition, the rotating portion 21 is located between the handle portion 22 and the plug portion 23, so that the handle portion 22 and the plug portion 23 can rotate around the rotating portion 21. The mounting portion 31 of the positioning block 3 is located between the first cantilever 24 and the second cantilever 25, so that the wrench 2 can rotate relative to the positioning block 3, and the positioning block 3 can slide relative to the base 11, thereby enabling the wrench 2 to be closed relative to the base 11, with the rotating shaft 4 located in the first position 118 of the base 11; or, the wrench 2 can be opened relative to the base 11, with the rotating shaft 4 located in the second position 119 of the base 11. In addition, the distance between the handle portion 22 and the rotating portion 21 is greater than the distance between the plug portion 23 and the rotating portion 21, so that the user can easily rotate the wrench 2, thereby improving the user experience.

[0087] In other embodiments, the first rotating post 211 may be disposed on the first sidewall 112 of the base 1, and the second rotating post 212 may be disposed on the second sidewall 113 of the base 1, with the first rotating post 211 and the second rotating post 212 positioned between the first sidewall 112 and the second sidewall 113. The first mounting hole 1123 and the second mounting hole 1133 are respectively disposed on the rotating portion 21 of the wrench 2. By engaging the first rotating post 211 with the first mounting hole 1123 and the second rotating post 212 with the second mounting hole 1133, a rotational connection between the wrench 2 and the base 1 may also be achieved, although this application does not impose strict limitations on this.

[0088] Please refer to the Figure 5A 、 Figures 7 to 9 In some embodiments, the plug-in portion 23 is provided with a first plug-in hole 231 and a second plug-in hole 232, which are arranged opposite to each other and are respectively located at the first cantilever 24 and the second cantilever 25. The rotating shaft 4 is inserted into the first plug-in hole 231 and the second plug-in hole 232 of the plug-in portion 23. At the same time, the rotating shaft 4 is passed through the first slide groove 1122, the second slide groove 1132 of the base body 11, and the mounting groove 311 of the positioning block 3, that is, the rotating shaft 4 is fixed to the plug-in portion 23 of the wrench 2 and can slide in the first slide groove 1122, the second slide groove 1132, and the mounting groove 311. When the wrench 2 rotates relative to the base body 11, the rotating shaft 4 moves between the first position 118 and the second position 119 relative to the base body 11. Illustratively, the first position 118 can be located at an end of the first slot 1122 close to the third side wall 115, and the second position 119 can be located at an end of the first slot 1122 away from the third side wall 115. Illustratively, when the wrench 2 rotates relative to the base 11, the rotating shaft 4 moves within the first slot 1122 and within the mounting groove 311, and the rotating shaft 4 drives the locking block 3 to move relative to the base 11, thereby causing the base 11 to also move relative to the locking block 3.

[0089] In this embodiment, when the plug-in portion 23 of the wrench 2 rotates around the rotating portion 21, the rotating shaft 4 needs to move simultaneously in the mounting groove 311 of the locking block 3 and the first slide groove 1122 and the second slide groove 1132 of the seat body 11. Since the locking block 3 and the seat body 11 can slide relative to each other, and the extension trajectory of the mounting groove 311 is different from the extension trajectory of the first slide groove 1122 and the second slide groove 1132, the rotating shaft 4 can push the locking block 3 and the seat body 11 to slide relative to each other when rotating.

[0090] In some embodiments, the handle portion 22 of the wrench 2 is further provided with a screw hole 221, which is used to install fasteners such as screws. When the wrench 2 is closed relative to the base body 11, the wrench 2 can be further fixed to the base body 11 by fasteners such as screws to prevent the handle portion 22 of the wrench 2 from rotating relative to the base body 11, causing the upper cover lock 10 to be unlocked.

[0091] Please refer to Figure 1 、 Figure 2 、 Figures 11 to 12 , Figure 11 yes Figure 4 The structure diagram of the bracket 12 in some embodiments is shown. Figure 12 yes Figure 1 The server 1000 shown is a schematic diagram of a partial cross-sectional structure along line BB in some embodiments.

[0092] In some embodiments, the bracket 12 may include a first portion 121 and a second portion 122, wherein the first portion 121 is connected to the second portion 122. The first portion 121 is disposed opposite to the top plate 201 of the upper cover 20, and the second portion 122 is disposed opposite to the third side wall 115 of the base 11. The first portion 121 and the second portion 122 may both be plate-like structures. The first portion 121 is fixed to the upper cover 20, so that the bracket 12 and the base 11 maintain a relatively stable positional relationship. Exemplarily, the first portion 121 is recessed on the side facing away from the upper cover 20 to form an escape space 1211, and the upper cover 20 is partially located in the escape space 1211. In addition, the escape space 1211 of the bracket 12 can also serve as a positioning and / or limiting function to reduce the difficulty of installing the bracket 12. The first portion 121 is provided with a plurality of second columns 1212, and the plurality of second columns 1212 are arranged at intervals. The top plate 201 of the upper cover 20 is further provided with a plurality of second positioning holes 2014, into which the second posts 1212 are mounted. The second posts 1212 of the upper cover 20 cooperate with the second positioning holes 2014 of the bracket 12, and the second posts 1212 serve to position and / or secure the bracket 12 during assembly with the upper cover 20. For example, the bracket 12 can be riveted to the upper cover 20 via the second posts 1212. Alternatively, the bracket 12 can be welded to the upper cover 20, although this disclosure is not strictly limited to this method.

[0093] In some other embodiments, the base 11 and the bracket 12 can be connected indirectly or directly. For example, the bracket 12 can be directly fixed to the base 11 to form an integrated structural component with the base 11. This application does not strictly limit this.

[0094] Please refer to the Figure 2 、 Figure 9 and Figure 12In some embodiments, the upper cover lock 10 may further include a snap-fitting seat 101, the snap-fitting seat 101 being fixed to the base 200, and the snap-fitting block 3 being snap-fitted to the snap-fitting seat 101. Exemplarily, the snap-fitting seat 101 may include a positioning post 1011 and a fixing seat 1012, and the fixing seat 1012 is fixed to the bottom plate 2001 of the base 200. For example, the fixing seat 1012 may be fixed to the base 200 by riveting or welding. One end of the positioning post 1011 is fixed to the fixing seat 1012, and the other end of the positioning post 1011 passes through the fourth mounting hole 1142 of the base body 11 and is snap-fitted to the snap-fitting hole 331 of the snap-fitting block 3, and the positioning post 1011 can move in the fourth mounting hole 1142 along the second direction Y.

[0095] In this embodiment, the engaging seat 101 is fixed to the base 200, and the engaging block 3 engages the positioning post 1011 of the engaging seat 101, thereby fixing the engaging block 3 relative to the base 200. The base 11 is fixed to the upper cover 20, thereby fixing the base 11 relative to the upper cover 20. When the wrench 2 rotates relative to the base 11, it drives the rotating shaft 4 to slide simultaneously within the first slide groove 1122, the second slide groove 1132, and the mounting groove 311. Since the extension trajectory of the mounting groove 311 is different from the extension trajectory of the first slide groove 1122 and the second slide groove 1132, the engaging block 3 and the base 11 slide relative to each other, further driving the base 200 and the upper cover 20 to slide relative to each other. The positioning post 1011 moves in the fourth mounting hole 1142, which can limit the upward movement distance of the positioning post 1011 in the second direction Y. After the positioning post 1011 is inserted into the positioning block 3, the cooperation between the positioning post 1011 and the fourth mounting hole 1142 can further limit the movement distance of the upper cover 20 relative to the base 200, thereby facilitating the alignment of the upper cover 20 and the base 200 when the upper cover lock 10 is locked. The positioning post 1011 of the connector 101 also plays a positioning and / or limiting role, so as to facilitate the assembly of the upper cover assembly 100 and the base 200.

[0096] For example, when the upper cover lock 10 changes from the unlocked state to the locked state, the handle portion 22 of the wrench 2 moves toward the side closer to the base 11, and the wrench 2 drives the rotating shaft 4 to rotate from the second position 119 to the first position 118, pushing the blocking block 3 and the base 11 to slide relative to each other in the second direction Y, further driving the base 200 and the upper cover 20 to slide relative to each other in the second direction Y, that is, the upper cover 20 moves relative to the base 200 in the second direction Y. When the upper cover lock 10 changes from the locked state to the unlocked state, the handle portion 22 of the wrench 2 rotates toward the side away from the base 11, and the wrench 2 drives the rotating shaft 4 to rotate from the first position 118 to the second position 119, pushing the blocking block 3 and the base 11 to slide relative to each other in the second direction Y, further driving the base 200 and the upper cover 20 to slide relative to each other in the second direction Y, that is, the upper cover 20 moves relative to the base 200 in the opposite direction of the second direction Y.

[0097] Please refer to Figure 3 、 Figure 4 、 Figure 11 and Figure 13 , Figure 13 yes Figure 4 The structure of the crank 5 shown is a schematic diagram in some embodiments.

[0098] In some embodiments, the crank 5 is rotatably connected to the base 1, and the first end of the connecting rod 6 is rotatably connected to one end of the crank 5, while the other end of the crank 5 can be used to abut the rotating shaft 4. The crank 5 can include a middle portion 52, a first end 51 connected to the middle portion 52, and a second end 53. The middle portion 52 is rotatably connected to the bracket 12, the first end 51 is rotatably connected to the first end of the connecting rod 6, and the second end 53 is used to abut the rotating shaft 4 when the rotating shaft 4 is in the first position 118. For example, the first end 51, the middle portion 52, and the second end 53 of the crank 5 can be plate-like structures, and the crank 5 can be an integrated structural component, for example, the crank 5 can be formed by bending a plate. The first end 51 and the middle portion 52 can be located on the same plate and disposed opposite the second portion 122 of the bracket 12. The second end 53 can include a first plate 531, a second plate 532, and a third plate 533. The second plate 532 connects the first plate 531 and the third plate 533, and the first plate 531 and the third plate 533 are disposed opposite each other. The third plate 533 is connected to one end of the middle portion 52 , and the first plate 531 can be used to abut against the rotating shaft 4 . The first end portion 51 forms a first end of the crank 5 , and the second end portion 53 forms the other end of the crank 5 .

[0099] The middle portion 52 has a first through-hole 521, the first end portion 51 has a second through-hole 511, the second portion 122 of the bracket 12 has a third through-hole 1221, and the first end of the connecting rod 6 has a fourth through-hole 61. The lid lock 10 may further include a first connector 102 and a second connector 103, which may be rivets. The first connector 102 is mounted between the first through-hole 521 of the middle portion 52 and the third through-hole 1221 of the bracket 12, thereby rotatably connecting the crank 5 to the bracket 12. The second connector 103 is mounted between the second through-hole 511 of the first end portion 51 and the fourth through-hole 61 of the connecting rod 6, thereby rotatably connecting the crank 5 to the connecting rod 6. When the wrench 2 rotates relative to the base 1 about a first rotation center, the wrench 2 drives the rotating shaft 4 to rotate relative to the base 1 about the first rotation center. The rotating shaft 4 can abut the crank 5, thereby causing the crank 5 to rotate relative to the bracket 12 of the base 1 about a second rotation center, which is not parallel to the first rotation center. For example, the first rotation center may be perpendicular to or intersect the second rotation center. The first rotation center may be located at the axis of the first mounting hole 1123 , and the second rotation center may be located at the axis of the third through hole 1221 .

[0100] In this embodiment, the design of the first end 51, middle portion 52, and second end 53 of the crank 5 can alter the rotational motion. As the wrench 2 rotates about the first rotational center, the rotating shaft 4 pushes the crank 5 to rotate about the middle portion 52, thereby converting the rotational motion into rotation of the crank 5 about the second rotational center. The combination of the crank 5 and the connecting rod 6 allows the crank 5 to transmit force and displacement to the pin 7, which is located away from the base 1, through the connecting rod 6. The connecting rod 6 converts the rotation of the crank 5 into the movement of the pin 7, allowing the pin 7 to extend relative to the first side plate 202 of the upper cover 20 and be inserted between the first side plate 202 of the upper cover 20 and the second side plate 2002 of the base 200.

[0101] In some other embodiments, the crank 5 may also be in other shapes, which is not strictly limited in this application.

[0102] Please refer to Figure 3 、 Figure 4 、 Figure 14 and Figure 15 , Figure 14 yes Figure 4 The schematic diagram of the partially exploded structure of the cover lock 10 assembly in some embodiments is shown. Figure 15 yes Figure 4 The illustrated schematic diagram is a partial structural cross-section of the cover lock 10 assembly along CC in some embodiments.

[0103] In some embodiments, the pin 7 rotatably connects to the second end of the connecting rod 6. The second end of the connecting rod 6 is provided with a fifth through-hole 62, and the end of the pin 7 proximate to the connecting rod 6 is provided with a sixth through-hole 71. The lid lock 10 may further include a third connector 104, which may be a rivet. The third connector 104 is mounted between the fifth through-hole 62 of the connecting rod 6 and the sixth through-hole 71 of the pin 7, thereby rotatably connecting the connecting rod 6 and the pin 7.

[0104] In some embodiments, the upper cover lock 10 may further include a support 9, which is fixed to the upper cover 20. The end of the pin 7 facing away from the connecting rod 6 is inserted into the support 9, and the elastic member 8 is located between the support 9 and the pin 7. The support 9 may include a limit member 91 and a baffle 92. The baffle 92 is fixed to the side of the limit member 91 close to the connecting rod 6. The baffle 92 and the limit member 91 together form a limit space 93, and the limit space 93 extends along the first direction X. The baffle 92 can be fixed to the limit member 91 by welding or riveting. The baffle 92 is provided with a seventh through hole, and the limit member 91 is provided with an eighth through hole. The pin 7 is partially installed in the seventh through hole of the baffle 92, the limit space 93, and the eighth through hole of the limit member 91, and the pin 7 can move upward in the first direction X relative to the support 9.

[0105] In this embodiment, the support 9 is fixed to the upper cover 20, and the pin 7 is inserted into the base 1, so that the pin 7 can only move upward in the first direction X. In conjunction with the crank 5 and the connecting rod 6, the rotation of the crank 5 is converted into the movement of the pin 7.

[0106] In some embodiments, the elastic member 8 is installed in the limiting space 93, and the pin 7 is passed through the elastic member 8. Exemplarily, the elastic member 8 can be a spring. The pin 7 is provided with a positioning plate 72, which is located at the end of the pin 7 away from the connecting rod 6. The positioning plate 72 is located in the limiting space 93 of the support 9 and between the baffle 92 and the limiting member 91. The positioning plate 72 is used to prevent the pin 7 from separating from the support 9. When the pin 7 moves approximately in the first direction X, the elastic member 8 is in a compressed state to generate an elastic force, which is used to push the pin 7 to move in the opposite direction of the first direction X.

[0107] In this embodiment, the elastic member 8 is located between the support 9 and the pin 7. The elastic force of the elastic member 8 can push the pin 7 to move in the opposite direction of the first direction X. That is, under the action of the elastic member 8, the pin 7 can automatically retract without applying external force, making the unlocking operation of the upper cover assembly 100 easier. Under the combined action of the crank 5 and the elastic member 8, the pin 7 can reciprocate, thereby inserting into the first side plate 202 of the upper cover 20, or retracting relative to the first side plate 202 of the upper cover 20.

[0108] In some embodiments, the crank 5, connecting rod 6, pin 7, and elastic member 8 may constitute the first latch assembly 105 of the lid lock 10. The lid lock 10 may further include a second latch assembly 106. The second latch assembly 106 is symmetrical with the first latch assembly 105 and is located on the side of the base 1 facing away from the first latch assembly 105. The rotating shaft 4 is further configured to abut the crank 5 of the second latch assembly 106 when the wrench 2 is closed relative to the base 1. The first latch assembly 105 and the second latch assembly 106 may also each include a support 9. It will be understood that the second latch assembly 106 is generally symmetrical with the first latch assembly 105 with respect to the base 1, and the second latch assembly 106 may be configured similarly to the first latch assembly 105. When the upper cover lock 10 is changed from the unlocked state to the locked state, the rotating shaft 4 abuts against the crank 5 of the first latch assembly 105 and the crank 5 of the second latch assembly 106, so that the pin 7 of the first latch assembly 105 and the pin 7 of the second latch assembly 106 move in opposite directions, thereby causing the pin 7 of the first latch assembly 105 and the pin 7 of the second latch assembly 106 to be inserted into the upper cover 20 and the base 200 respectively.

[0109] In this embodiment, the pin 7 of the first latch assembly 105 and the pin 7 of the second latch assembly 106 are respectively inserted into the upper cover 20 and the base 200. That is, the first latch assembly 105 can fix the first side plate 202 on one side of the upper cover 20 to the second side plate 2002 on the corresponding side of the base 200, and the second latch assembly 106 can fix the first side plate 202 on the other side of the upper cover 20 to the second side plate 2002 on the other side of the base 200. As a result, the first side plates 202 on both sides of the upper cover 20 and the second side plates 2002 on both sides of the base 200 are constrained and fixed. Compared with single-sided constrained fixation, double-sided constrained fixation can significantly improve the torsional rigidity of the server. In addition, the upper cover lock 10 has a simple structure and is easy to operate, which can achieve rapid assembly and disassembly of the upper cover assembly 100.

[0110] Please refer to Figures 16 to 18 , Figure 16 is a partial structural diagram of the upper cover lock 10 in different states in some embodiments, Figure 17 yes Figure 16 The cross-sectional structure diagram along DD when the upper cover lock 10 is in the locked state is shown. Figure 18 yes Figure 1 The server 1000 is shown as a schematic cross-sectional structural diagram along EE when the upper cover lock 10 is in a locked state.

[0111] In some embodiments, the upper cover 20 is mounted on the base 200, with the first side panel 202 of the upper cover 20 disposed opposite the second side panel 2002 of the base 200, wherein the second side panel 2002 may be located on the inner side of the first side panel 202. The first side panel 202 of the upper cover 20 is provided with a first pin hole, and the second side panel 2002 of the base 200 is provided with a second pin hole. When the upper cover lock 10 is in the locked state, the wrench 2 is closed relative to the base 1, i.e., the wrench 2 is in the closed position, the first pin hole of the first side panel 202 is aligned with the second pin hole of the second side panel 2002, the rotating shaft 4 is in the first position 118 and abuts the other end of the crank 5, and the pin 7 extends relative to the first side panel 202 of the upper cover 20, plugging the first side panel 202 of the upper cover 20 and the second side panel 2002 of the base 200. For example, when the wrench 2 is closed relative to the base body 11 of the base 1, the wrench 2 drives the rotating shaft 4 to the first position 118 of the base body 11, and the fourth side wall 116 of the base body 11 is away from the positioning portion 33 of the blocking block 3. The rotating shaft 4 abuts the second end 53 of the crank 5, and the first end 51 of the crank 5 is away from the base body 11. The connecting rod 6 pushes the pin 7 to extend relative to the first side plate 202 of the upper cover 20, plugging the first side plate 202 of the upper cover 20 and the second side plate 2002 of the base 200. The pin 7 plugs into the first pin hole of the first side plate 202 and the second pin hole of the base 200, thereby fixing the upper cover 20 and the base 200 together. At this time, the elastic member 8 is in a compressed state and can generate an elastic force, which can push the pin 7 away from the first side plate 202 of the upper cover 20.

[0112] Compared to servers in the prior art that use pins to restrain the top cover and base, in this embodiment, the top cover assembly 100 connects and secures the top cover 20 and first side panel 202 via a pin 7. This creates a stable fixation between the top cover 20 and the first side panel 202, helping to strengthen the constraint between the top cover 20 and the base 200 of the server 1000 and improve the overall torsional rigidity of the server 1000. This top cover lock 10 is suitable for servers 1000 that are larger and heavier. Furthermore, when transporting the server 1000, the top cover 20 will not slide relative to the base 200, which helps improve the reliability of the server 1000. Furthermore, the top cover lock 10 utilizes a wrench 2 in conjunction with the pin 7 to drive the crank 5 connecting rod 6 mechanism to push the pin 7. The top cover lock 10 has a simple structure and is easy to operate, enabling rapid locking of the top cover 20 and base 200.

[0113] Please refer to Figure 16 、 Figure 19 and Figure 20 , Figure 19 yes Figure 16 The cross-sectional structure diagram along DD when the upper cover lock 10 is in the unlocked state is shown. Figure 20 yes Figure 1The server 1000 is shown as a schematic cross-sectional structural diagram along EE when the upper cover lock 10 is in an unlocked state.

[0114] In some embodiments, when the upper cover lock 10 is in the unlocked state, the wrench 2 is opened relative to the base 1, that is, the wrench 2 is in the fully open position, the rotating shaft 4 is in the second position 119 and disengaged from the crank 5, the first end 51 of the crank 5 is close to the base 11, and the pin 7 is retracted relative to the first side plate 202 of the upper cover 20 under the elastic force. Exemplarily, when the wrench 2 is opened relative to the base 11 of the base 1, the hand drives the rotating shaft 4 to the second position 119 of the base 11, and the fourth side wall 116 of the base 11 is away from the positioning portion 33 of the locking block 3. The rotating shaft 4 is disengaged from the second end 53 of the crank 5, and under the elastic force of the elastic member 8, the pin 7 is retracted relative to the first side plate 202 of the upper cover 20, the upper cover 20 is released from the base 200, and the upper cover 20 is able to move relative to the base 200.

[0115] In this embodiment, when the rotating shaft 4 abuts the crank 5, the pin 7 extends relative to the first side plate 202 of the upper cover 20, causing the elastic member 8 to be compressed and generate an elastic force. When the rotating shaft 4 disengages from the crank 5, the abutment of the rotating shaft 4 on the crank 5 is removed, and the connecting rod 6 and the pin 7 are free. The elastic force of the elastic member 8 causes the pin 7 to move away from the first side plate 202, and the pin 7 is no longer inserted into the upper cover 20 and the base 200, thereby unlocking the upper cover assembly 100. Under the action of the elastic member 8, the pin 7 automatically retracts without the application of external force, making the unlocking operation of the upper cover assembly 100 simpler.

[0116] Please refer to Figure 12 、 Figure 18 、 Figure 20 and Figure 21 , Figure 21 yes Figure 16 The cross-sectional structure diagram along DD when the upper cover lock 10 is in a half-open state is shown.

[0117] In some embodiments, when the upper cover lock 10 transitions from the unlocked state to the locked state, the wrench 2 drives the rotating shaft 4 to rotate, causing the rotating shaft 4 to slide within the first sliding groove 1122, the second sliding groove 1132, and the mounting groove 311, simultaneously driving the locking block 3 and the base 11 to move relative to each other. Since the locking block 3 is fixed relative to the base 200 and the base 11 is fixed to the upper cover 20, the base 11 drives the upper cover 20 to move relative to the base 200. Rotating the wrench 2 places the wrench 2 in the half-open position, i.e., the upper cover lock 10 is in the half-open state. The rotating shaft 4 is in the third position 120 of the base 11, the rotating shaft 4 is in contact with the crank 5, the positioning block of the locking block 3 is away from the fourth side wall 116 of the base 11, and the upward movement of the base 11 in the second direction Y is limited by the positioning post 1011 of the engaging base 101. The upper cover 20 is fully aligned with the base 200, and the first pin hole of the first side plate 202 is aligned with the second pin hole of the second side plate 2002. The wrench 2 is further rotated to the covering position, the rotating shaft 4 is rotated to the first position 118 and abuts against the other end of the crank 5, driving the crank 5 to rotate relative to the support 9, and driving the pin 7 through the connecting rod 6, so that the pin 7 overcomes the elastic force of the elastic member 8 and extends relative to the first side plate 202, and the pin 7 is inserted into the first pin hole of the first side plate 202 and the second pin hole of the second side plate 2002, thereby fixing the upper cover 20 and the base 200 relatively.

[0118] In some embodiments, when the wrench 2 rotates from the closed position to the partially open position, the relative position of the upper cover 20 and the base 200 remains unchanged, the supporting force of the rotating shaft 4 on the crank 5 gradually decreases, and the pin 7, under the action of the elastic member 8, retracts relative to the first side plate 202 of the upper cover 20, releasing the upper cover 20 and the base 200. After the pin 7 retracts, the wrench 2 continues to rotate from the partially open position to the fully open position, and the rotating shaft 4 slides within the first slide groove 1122, the second slide groove 1132, and the mounting groove 311, simultaneously driving the retaining block 3 and the base 11 to move relative to each other. Because the retaining block 3 is fixed relative to the base 200 and the base 11 is fixed to the upper cover 20, the base 11 drives the upper cover 20 to move relative to the base 200, and the upper cover 20 is opened.

[0119] Please refer to Figure 5A 、 Figure 22 and Figure 23 , Figure 22 yes Figure 4 The schematic structural diagram of the positioning block 3 in other embodiments is shown. Figure 23 yes Figure 1 The server 1000 is shown as a schematic diagram of a cross-sectional structure along line BB in some other embodiments. This embodiment may include most of the technical features of the previous embodiment. The following only explains the differences between the two embodiments, and the same contents between the two embodiments are not repeated.

[0120] In some embodiments, the upper cover lock 10 may include a base 1, a wrench 2, a locking block 3, a rotating shaft 4, a crank 5, a connecting rod 6, a pin 7, an elastic member 8, and a support 9. The base 1 is fixed to the top plate 201 of the upper cover 20, and the wrench 2 is used to rotate and connect to the base 1. The rotating shaft 4 is used to insert the wrench 2. When the wrench 2 rotates relative to the base 1, the rotating shaft 4 moves relative to the base 1 between a first position 118 and a second position 119. The locking block 3 is used to slide and connect to the base 1, the crank 5 is rotationally connected to the base 1, the first end of the connecting rod 6 is rotationally connected to one end of the crank 5, and the pin 7 is rotationally connected to the second end of the connecting rod 6. The pin 7 is inserted into the support 9, and the support 9 is fixed to the upper cover 20. When the wrench 2 is closed relative to the base 1, the rotating shaft 4 is in the first position 118 and abuts the other end of the crank 5. The pin 7 extends relative to the first side plate 202 of the upper cover 20 and connects the first side plate 202 of the upper cover 20 with the second side plate 2002 of the base 200. When the wrench 2 is opened relative to the base 1, the rotating shaft 4 is in the second position 119 and disengages the crank 5. The pin 7 retracts relative to the first side plate 202 of the upper cover 20 under the elastic force. The base 1 may include a base 11 and a bracket 12, with the bracket 12 located on one side of the base 11.

[0121] In some embodiments, the positioning block 3 may include a mounting portion 31, a sliding portion 32, and a positioning portion 33, wherein the sliding portion 32 connects the mounting portion 31 and the positioning portion 33. The thickness of the mounting portion 31 in the third direction Z is greater than the thickness of the sliding portion 32 and the positioning portion 33 in the third direction Z, and the mounting portion 31 is at least partially located in the third mounting hole 1141 of the base 11. The mounting portion 31 is provided with a mounting groove 311, and the extension trajectory of the mounting groove 311 is different from the extension trajectory of the first slide groove 1122 and the second slide groove 1132. Exemplarily, the mounting groove 311 can be roughly an arc-shaped groove, and the extension trajectory can be composed of two arcs with opposite bending directions, extending generally along the third direction Z. In some other embodiments, the mounting groove 311 can also be other shapes. The rotating shaft 4 is provided in the mounting groove 311 and can move in the mounting groove 311.

[0122] Please refer to Figure 3 、 Figures 24 to 26 , Figure 24 yes Figure 3 The schematic diagram of the partial structure of the cover lock 10 in other embodiments is shown. Figure 25 yes Figure 24 The exploded structural diagram of the cover lock 10 is shown in FIG. Figure 26 yes Figure 24 The cross-sectional structure diagram of the cover lock 10 is shown along FF.

[0123] In some embodiments, one end of the elastic member 8 is fixed to the crank 5, and the other end of the elastic member 8 is fixed to the bracket 12. When the rotating shaft 4 abuts the crank 5, the elastic member 8 generates an elastic force. When the rotating shaft 4 is disengaged from the crank 5, the crank 5 rotates relative to the bracket 12 under the elastic force, driving the connecting rod 6 to move toward the side closer to the base 1, and the pin 7 retracts relative to the first side plate 202 of the upper cover 20. Exemplarily, the bracket 12 may include a first portion 121 and a second portion 122, wherein the first portion 121 is connected to the second portion 122. The crank 5 may include a middle portion 52 and a first end 51 and a second end 53 connected to the middle portion 52. The middle portion 52 is rotatably connected to the second portion 122 of the bracket 12, the first end 51 is rotatably connected to the connecting rod 6, and the second end 53 is used to abut the rotating shaft 4. The first end 51 and the middle portion 52 may be located on the same plate and arranged opposite the second portion 122 of the bracket 12.

[0124] The lid lock 10 may further include a first connector 102 that rotatably connects the middle portion 52 and the bracket 12. Exemplarily, the middle portion 52 of the crank 5 has a first through-hole 521, and the bracket 12 has a third through-hole 1221. The first connector 102 is mounted in the first through-hole 521 of the middle portion 52 and the third through-hole 1221 of the bracket 12, thereby rotatably connecting the crank 5 and the bracket 12. The first connector 102 may be a rivet. The elastic member 8 is a torsion spring that is sleeved on the first connector 102 and fixedly connects the middle portion 52 and the second portion 122 of the bracket 12. Exemplarily, the elastic member 8 has a first hook 81 and a second hook 82. The first connector 102 may include a first stopper 1021, a connecting portion 1022, and a second stopper 1023. The connecting portion 1022 connects the first stopper 1021 and the second stopper 1023. The connecting portion 1022 is installed in the first through hole 521 and the third through hole 1221 . The first limiting portion 1021 abuts against the crank 5 . The second limiting portion 1023 abuts against the second portion 122 of the bracket 12 . The elastic member 8 is sleeved on the outside of the connecting portion 1022 .

[0125] A first boss 1024 is provided on the side of the first limiting portion 1021 facing the second limiting portion 1023, and a second boss 1025 is provided on the side of the second limiting portion 1023 facing the first limiting portion 1021. The first boss 1024 and the second boss 1025 are arranged opposite each other. The first boss 1024 and the second boss 1025 are used to constrain the elastic member 8 between the first limiting portion 1021 and the second limiting portion 1023. The first boss 1024 abuts the middle portion 52, while the second boss 1025 abuts the second portion 122. Both the first boss 1024 and the second boss 1025 have openings through which the first hook 81 and the second hook 82 of the elastic member 8 can extend. The middle portion 52 also has a retaining portion 522, to which the first hook 81 of the elastic member 8 engages. The second portion 122 of the bracket 12 further includes a retaining hole 1222, spaced apart from the third through hole 1221. The second hook 82 of the elastic member 8 is mounted in the retaining hole 1222 and engages the second portion 122. When the rotating shaft 4 abuts the crank 5, the second end 53 of the crank 5 rotates away from the base 11, and the elastic member 8 is stretched, generating an elastic force. When the rotating shaft 4 disengages from the crank 5, the elastic force causes the second end 53 of the crank 5 to rotate toward the base 11, driving the connecting rod 6 toward the base 1, causing the pin 7 to retract relative to the first side plate 202 of the upper cover 20.

[0126] In this embodiment, when the rotating shaft 4 abuts the crank 5, the second end 53 of the crank 5 rotates away from the base 11, causing the elastic member 8 to be in a stretched state, thereby generating an elastic force. When the rotating shaft 4 disengages from the crank 5, the abutting force of the rotating shaft 4 on the crank 5 is removed, and the connecting rod 6 and the pin 7 are free. The elastic force of the elastic member 8 causes the second end 53 of the crank 5 to rotate toward the base 11, and the pin 7 retracts relative to the first side plate 202 of the upper cover 20, thereby unlocking the upper cover assembly 100. Under the action of the elastic member 8, the crank 5 automatically retracts without the application of external force, making the unlocking operation of the upper cover assembly 100 simpler.

[0127] In some other embodiments, one end of the elastic member 8 can be connected to the connecting rod 6, and the other end of the elastic member 8 is connected to the bracket 12. When the rotating shaft 4 abuts the crank 5, the second end 53 of the crank 5 rotates toward the side away from the seat 11, driving the connecting rod 6 to move toward the side away from the bracket 12, and the elastic member 8 is in a stretched state to generate an elastic force. When the rotating shaft 4 is separated from the crank 5, the abutting force of the rotating shaft 4 on the crank 5 is removed, and the connecting rod 6 and the pin 7 are in a free state. The elastic force of the elastic member 8 causes the connecting rod 6 to rotate toward the side close to the bracket 12, and the pin 7 retracts relative to the first side plate 202 of the upper cover 20, thereby unlocking the upper cover assembly 100. This application does not strictly limit the specific connection relationship of the elastic member 8.

[0128] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
