Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and in particular to an electronic device. BACKGROUND

[0002] With the rise of big data, cloud computing and AI (Artificial intelligence), the application demand of electronic devices such as servers and supercomputers is becoming more and more extensive. In order to improve competitiveness, electronic devices need to increase the configuration density to improve the computing speed and storage capacity, and the improvement of computing speed and storage capacity easily leads to the increasing power consumption of electronic devices. At present, since part of the structure of the upper cover lock of the electronic device is arranged on the chassis base of the electronic device, the air inlet of the electronic device is easily blocked, which leads to the increasing air resistance of the electronic device and affects the heat dissipation performance of the electronic device. SUMMARY

[0003] Embodiments of the present application provide an electronic device, which can reduce the system air resistance of the whole electronic device and improve the heat dissipation performance of the electronic device.

[0004] In a first aspect, the present application provides an electronic device, comprising:

[0005] a chassis comprising a box body, a first cover plate and a second cover plate, the first cover plate and the second cover plate being arranged on the box body, the first cover plate and the second cover plate being arranged along a first direction, the first direction being a length direction of the electronic device, the second cover plate being provided with a mounting through hole, the mounting through hole being in communication with the inside of the chassis and the outside of the chassis; and

[0006] a lock holding assembly comprising a fixing member, a supporting member and a wrench, the fixing member being fixed to the second cover plate, the fixing member being provided with a receiving groove, the receiving groove being in communication with the mounting through hole, one end of the supporting member being connected to the first cover plate, the other end of the supporting member extending into the inside of the box body and being located below the fixing member, the supporting member being provided with a first through groove, the first through groove extending along the first direction, the wrench being connected to the second cover plate and passing through the mounting through hole and the first through groove, the wrench being capable of rotating relative to the second cover plate to be buckled with the receiving groove to drive the second cover plate to be locked with the box body and the first cover plate.

[0007] It can be understood that when the internal components of the electronic device need to be maintained, the first cover plate and the box body can serve as static components in the case, and the second cover plate can serve as a dynamic component in the case. The second cover plate can be unlocked relative to the first cover plate and the box body through the locking assembly to realize the subsequent operation of the second cover plate being detached from the box and the first cover plate, so that the worker can disassemble, overhaul, replace, etc. operation on the internal components of the case. When the internal components of the electronic device end maintenance or do not need maintenance, the second cover plate can be locked relative to the first cover plate and the box body through the locking assembly, so that the first cover plate can be tightly connected with the box and the first cover plate, to ensure the overall strength of the case.

[0008] By providing the support member and connecting the support member to the first cover plate, the support member can support the movement of the dynamic component wrench in the locking assembly as a static component in the locking assembly because the position of the first cover plate relative to the case will not change. Because the connection strength between the first cover plate and the case is strong, directly connecting the support member to the first cover plate can also provide good cooperation between the support member and the first cover plate, effectively avoiding the problems of deforming the case base caused by pulling the case base during locking and unlocking operations, adversely affecting the subsequent fan module plug-in, etc. It is beneficial to make the overall strength of the case not affected during the locking and unlocking of the second cover plate and the box and the first cover plate, and has good reliability.

[0009] By providing the wrench and connecting the wrench to the second cover plate and the first through slot passing through the support member, the wrench can be in contact with the opposite ends of the first through slot through the rotational movement of the wrench relative to the second cover plate. Not only can one end of the first through slot serve as a rotational support point on the support member, but also provide a fulcrum point for the wrench when the wrench is rotated to contact it, thereby assisting the wrench to keep the second cover plate locked with the box and the first cover plate. The other end of the first through slot can also serve as another rotational support point on the support member, and provide a fulcrum point for the wrench when the wrench is rotated to contact it, thereby assisting the wrench to unlock the second cover plate relative to the box and the first cover plate.

[0010] In addition, since the support is connected to the first cover plate and the wrench is connected to the second cover plate, the locking assembly is located on one side of the top of the case. In the prior art, the upper cover lock is distributed on the bottom and the top of the case, and the upper cover lock seriously affects the air inlet of the case, resulting in the problems of high air resistance of the whole machine system and difficulty in improving the heat dissipation specification of the whole machine. In the technical solution of the present application, the locking assembly is concentratedly distributed on the top of the case, so that the air inlet channel in the case is permeable, and the adverse effects of the excessive occupation of the air inlet channel by the upper cover lock on the selection and arrangement of the fan module in the equipment can be minimized, which is beneficial to improving the heat dissipation capacity of the whole machine.

[0011] In a possible implementation, the first through slot includes a first contact portion and a second contact portion oppositely arranged along the first direction, and the second contact portion is closer to the first cover plate relative to the first contact portion.

[0012] The wrench includes a key and a handle, the handle is rotationally connected to the second cover plate, one end of the handle passes through the first through slot, the other end of the handle is connected to the key, and the handle can rotate relative to the second cover plate to be in contact with the first contact portion, thereby driving the key to be engaged with the accommodation slot.

[0013] That is, the wrench can be rotated to be in contact with one end (i.e., the first contact portion) of the first through slot arranged along the first direction, thereby driving the second cover plate to be locked with the case and the first cover plate, so that the case is in a closed state.

[0014] Specifically, when the components in the case need to be maintained, the second cover plate needs to be detached from the case and the first cover plate, the key is actuated and pulled upward, so that the handle can rotate clockwise around the rotation center of the handle, thereby causing the key connected to the handle to be disengaged from the accommodation slot of the fixing member, so that the second cover plate is unlocked with the case and the first cover plate, and the second cover plate is pulled out relative to the case and the first cover plate. When the components in the case are completed, the key is actuated and pressed downward, so that the handle can rotate counterclockwise around the rotation center of the handle, thereby causing the key connected to the handle to be engaged with the accommodation slot of the fixing member, so as to lock the second cover plate with the case and the first cover plate.

[0015] It can be understood that when the case is in a closed state, the key is engaged with the accommodation slot, and the key and part of the handle can be flush with the second cover plate. At this time, the handle is in contact with the first contact portion, the handle extrudes the first contact portion backward, thereby causing the first contact portion to give the handle a forward force to help the second cover plate to be locked with the case and the first cover plate. When the case is switched from the closed state to the open state, the key is disengaged from the accommodation slot, and the key and part of the handle can protrude relative to the second cover plate. At this time, the handle is in contact with the second contact portion, the handle extrudes the second contact portion forward, thereby causing the second contact portion to give the handle a backward force to help the second cover plate to be unlocked with the case and the first cover plate.

[0016] In a possible implementation, the surface of the first contact portion and / or the second contact portion in contact with the handle is curved.

[0017] In this arrangement, the surface of the first contact portion and / or the second contact portion in contact with the wrench can be a smooth curved surface, which is conducive to reducing the problem of the wrench being worn due to the first contact portion and / or the second contact portion having corners. The surface of the first contact portion and / or the second contact portion can also be adapted to the surface morphology of the wrench to present a curved surface, which is conducive to increasing the contact area of the first contact portion and / or the second contact portion with the wrench and improving the contact stability and reliability of the first contact portion and / or the second contact portion with the wrench.

[0018] In a possible implementation, the wrench can be rotated relative to the second cover plate through the mounting through hole to disengage from the receiving groove and drive the second cover plate to be unlocked from the box body and the first cover plate.

[0019] In a possible implementation, the handle includes a handle body and a handle fixing portion, the handle body is rotationally connected to the second cover plate, the handle fixing portion is connected to one end of the handle body, the knob includes a base and a key, the base is provided with a mounting groove, the handle fixing portion is embedded in the mounting groove, the key is covered on one side of the base in which the handle fixing portion is embedded, and the key and the base cooperate to fix the handle fixing portion.

[0020] In this arrangement, when the base, the handle, and the key are sequentially stacked, one side of the handle fixing portion is limited by the base, and the other side of the handle fixing portion is limited by the key, so that the handle can be clamped in the base and the key, and the movement of the handle is limited by the cooperation of the key and the base.

[0021] In a possible implementation, the base includes a carrier plate, an inner layer baffle, and an outer layer baffle provided on the carrier plate, the outer layer baffle is located at the periphery of the inner layer baffle, the gap region between the outer layer baffle and the inner layer baffle forms the mounting groove, the handle fixing portion is provided with a second through groove penetrating through the handle fixing portion along the thickness direction of the handle fixing portion, the groove wall of the second through groove is in contact with the inner layer baffle, and the outer periphery of the handle fixing portion is in contact with the outer layer baffle.

[0022] In this arrangement, the handle fixing portion is nested in the base, so that the handle and the base can have good installation stability and reliability.

[0023] In a possible implementation, the inner layer of the baffle has a height smaller than that of the outer layer of the baffle, so that the inner layer of the baffle and the outer layer of the baffle cooperate to form a sliding rail, the key comprises a key body and a sliding body, the sliding body is connected to the key body, the sliding body is mounted to the sliding rail, and the sliding body is capable of sliding relative to the sliding rail to drive the key to slide relative to the base.

[0024] That is, in the second direction, the distance between the end of the inner layer of the baffle away from the carrier plate and the carrier plate is smaller than the distance between the end of the outer layer of the baffle away from the carrier plate and the carrier plate, so that the inner layer of the baffle and the outer layer of the baffle have a height difference, thereby enabling the inner layer of the baffle and the outer layer of the baffle to cooperate to form a sliding rail. The sliding rail can be used to mount the sliding body of the key thereon, thereby enabling the key to slide along the third direction on the base.

[0025] In a possible implementation, the carrier plate is provided with a third through slot penetrating through the carrier plate along the thickness direction of the carrier plate, and the inner layer of the baffle is arranged along the circumferential direction of the third through slot.

[0026] The key further comprises a key clamping portion, one end of the key clamping portion is connected to the key body, and the other end of the key clamping portion sequentially passes through the second through slot of the handle fixing portion and the third through slot of the carrier plate. The key clamping portion is capable of sliding relative to the fixing member under the drive of the key body.

[0027] In a possible implementation, the inner layer of the baffle is provided with a protruding portion, and the protruding portion is located in the space surrounded by the inner layer of the baffle and / or in the third through slot.

[0028] The key clamping portion is provided with a blind hole, and the blind hole is arranged in correspondence with the protruding portion.

[0029] The key further comprises an elastic member, the elastic member is sleeved on the protruding portion, and the elastic member is elastically abutted between the inner layer of the baffle and the bottom wall of the blind hole.

[0030] In this arrangement, the base and the key can have a tension force due to the presence of the elastic member. It can be understood that when the key is actuated to slide along the third direction, the elastic member is elastically deformed under force and is in a compressed state. When the force actuating the key is removed, the elastic member can provide a restoring force to the key due to the presence of the elastic member, thereby driving the key clamping portion to gradually move away from the protruding portion, so as to reset the key.

[0031] In a possible implementation, the fixing member is provided with a through slot penetrating through the fixing member along the thickness direction of the fixing member, the through slot is in communication with the receiving slot, and the through slot is used for the key clamping portion to pass through.

[0032] The other end of the key holding part passes through the accommodating groove and the through groove of the fixing member, and the other end of the key holding part is clamped with the fixing member, so that the second cover plate is locked with the first cover plate and the cabinet.

[0033] It can be understood that when the second cover plate is locked with the first cover plate and the cabinet, that is, the cabinet is in a closed state, the end of the key holding part away from the key body passes through the second through slot of the handle fixing part, the third through slot of the carrier plate, the accommodating groove of the fixing member and the through groove of the fixing member in sequence, and the end of the key holding part away from the key body is clamped with the fixing member by extending out of the fixing member, thereby ensuring the reliability and tightness of the locking between the second cover plate and the cabinet and the first cover plate.

[0034] When it is necessary to open the second cover plate to unlock the second cover plate from the first cover plate and the cabinet, the key is actuated to slide in the third direction. When the key holding part moves in the accommodating groove and the through groove of the fixing member to be out of contact with the through groove of the fixing member, the key body is lifted upward, so that the key holding part is separated from the accommodating groove and the through groove of the fixing member, thereby moving the wrench away from the fixing member, and the wrench can be rotated to help the second cover plate to be pulled out.

[0035] In a possible implementation, the locking assembly further comprises a first rotating shaft, the support member comprises a first connecting end and a second connecting end, the first rotating shaft is arranged in the first connecting end, the support member is rotationally connected with the first cover plate through the first rotating shaft, and the first through slot is arranged in the second connecting end.

[0036] It can be understood that the support member can also rotate relative to the first cover plate about the center line of the first rotating shaft, so that the support member can be rotationally connected with the first cover plate through the first rotating shaft. Specifically, the support member can be rotated relative to the first cover plate to be arranged obliquely to the first cover plate, so that most of the support member is located above the first cover plate. At this time, the support member does not block the gap region between the first cover plate and the fan module, and the hard disk back plate can be conveniently and quickly installed to the side of the first cover plate and the plurality of partitions close to the fan module, so that the assembly of the hard disk back plate is not blocked by the support member, the assembly process is simple, and the assembly efficiency of the electronic equipment is improved.

[0037] The support member can also be rotated relative to the first cover plate to be arranged parallel to the first cover plate, so that the support member is located in the gap region between the first cover plate and the fan module. At this time, the support member is rotated in place, and the support member can support the movement of the dynamic component (such as the wrench) in the locking assembly as a static component in the locking assembly.

[0038] In a possible implementation, the box body comprises a bottom plate, the bottom plate is arranged opposite to the first cover plate and the second cover plate, and the electronic device further comprises a fan module, the fan module is arranged on the bottom plate, the fan module is arranged in the first direction and spaced apart from the first cover plate, and the support is located in a gap region between the fan module and the first cover plate.

[0039] When the support is located in the box body, the maximum distance between the support and the second cover plate is less than the minimum distance between the support and the bottom plate.

[0040] It can be understood that, since cold air in the external environment enters the box body from the front end of the box body (that is, the side of the box body on which the first cover plate is arranged), the cold air becomes hot air after carrying the heat of the heat generating device in the box body and then exits from the rear end of the box body (that is, the side of the box body on which the second cover plate is located and away from the first cover plate). The support is located in the gap region between the fan module and the first cover plate, and therefore the support is actually located at the front end of the fan module. In addition, the distance between the support and the second cover plate of the box body is less than the distance between the support and the bottom plate of the box body, so that the support is closer to the second cover plate of the box body relative to the bottom plate of the box body. That is, the support is arranged on the top side of the box body.

[0041] On the one hand, compared with the prior art in which the part of the upper cover lock is arranged on the bottom plate of the box body, the fan module needs to avoid the upper cover lock to avoid being largely blocked by the upper cover lock. In the embodiment of the present application, the support is arranged on the top side of the box body. The space occupied by the electronic device due to the avoidance of the upper cover lock can be released, and the space is released to arrange more fan modules, so that the number of fan modules can be increased on the basis of ensuring the good working performance of the electronic device, thereby further improving the heat dissipation performance of the electronic device. On the other hand, arranging the support on the top side of the box body can make the air inlet channel of the fan module permeable, can minimize the space occupied by the fan module due to the arrangement of the upper cover lock and the adverse effects on the selection of the fan module, and can minimize the possibility of the problem that the air resistance of the whole system is increased and the heat dissipation specification of the whole machine is difficult to improve due to the blocking of the fan module by the lock holding assembly, thereby improving the heat dissipation capacity of the whole machine.

[0042] In a possible implementation, the electronic device is a server. BRIEF DESCRIPTION OF DRAWINGS

[0069] For the convenience of understanding, the terms involved in the embodiments of the present application are first explained.

[0070] and / or: is only a description of the association relationship of the associated objects, and indicates that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone.

[0071] Multiple: refers to two or more than two.

[0072] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either directly connected or indirectly connected through an intermediary.

[0073] The specific implementation of the present application will be clearly described below with reference to the accompanying drawings.

[0074] An embodiment of the present application provides an electronic device.

[0075] The electronic device may be, but is not limited to, a server, a router, a switch, a supercomputer, an AI (Artificial Intelligence) device, etc. For ease of understanding, the following description will take the electronic device as an example of a server, but it should be understood that the present invention is not limited thereto.

[0076] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural diagram of an electronic device 200 provided in an embodiment of the present application, Figure 2 yes Figure 1 An exploded schematic diagram of the electronic device 200 is shown.

[0077] In the embodiment of the present application, for the convenience of illustration, the length direction of the electronic device 200 is the first direction X, the height direction of the electronic device 200 is the second direction Z, and the width direction of the electronic device 200 is the third direction Y. The first direction X, the second direction Z and the third direction Y are perpendicular to each other.

[0078] The electronic device 200 may include a chassis 210 and a locking assembly 100. It is understandable that during the long-term use of the electronic device 200, the components in the chassis 210 need to be maintained frequently. Therefore, in the design of the electronic device 200, the upper cover of the chassis 210 (that is, the second cover 240 hereinafter) is a component that is frequently disassembled during operation and maintenance, and needs to be designed as a quickly removable component. In addition, the overall plug-in and pull-out force during the disassembly of the upper cover of the chassis 210 is large, and a certain amount of power assistance is required. Therefore, the tool-free disassembly locking assembly 100 has become an indispensable component of the entire electronic device 200. Specifically, the chassis 210 has an open state and a closed state. The locking assembly 100 enables the chassis 210 to switch between the open state and the closed state, and maintain it in the open state or the closed state. When the chassis 210 is in the closed state, the upper cover and the various components that make up the chassis 210 can remain relatively fixed. When the chassis 210 is in the open state, the upper cover can be detached from other structures in the chassis 210 to enable subsequent maintenance and assembly processes such as inspecting and replacing internal parts of the entire machine, as will be described in detail below.

[0079] It should be noted that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 200. In other embodiments of the present application, the electronic device 200 can include more or fewer components than illustrated, or combine certain components, or split certain components, or different arrangement of components. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0080] Please refer to Figure 1 and Figure 3 , Figure 3 is Figure 1 the structure diagram of the case 210 of the electronic device 200. The case 210 can include a box body 220, a first cover plate 230 and a second cover plate 240. The first cover plate 230 and the second cover plate 240 are connected to one side of the box body 220, and the first cover plate 230 and the second cover plate 240 are arranged along the first direction X (i.e. the length direction of the box body 220). Among them, the second cover plate 240 is the upper cover which needs to be frequently disassembled quickly as described above.

[0081] The box body 220 can include a bottom plate 2210, a first side plate 2220 and a second side plate 2230. The bottom plate 2210 can be used as a bearing plate of the case 210, and various components in the electronic device 200 are arranged on the bottom plate 2210. The bottom plate 2210, the first side plate 2220 and the second side plate 2230 cooperatively enclose a receiving space W of the box body 220, and the receiving space W can receive various components of the electronic device 200 such as fan modules, power supply modules, hard disk modules, circuit boards, etc. Specifically, the bottom plate 2210 can include a first end 2211 and a second end 2212, and the first end 2211 and the second end 2212 are oppositely arranged along the first direction X (i.e. the length direction of the bottom plate 2210). The first side plate 2220 and the second side plate 2230 are respectively arranged on both sides of the bottom plate 2210, and the first side plate 2220 and the second side plate 2230 are both extended along the first direction X and oppositely arranged along the third direction Y (i.e. the width direction of the bottom plate 2210).

[0082] The first side plate 2220 and / or the second side plate 2230 is provided with a plurality of first clamping grooves 2240, which are arranged at intervals on the first side plate 2220 and / or the second side plate 2230. Each first clamping groove 2240 comprises two groove walls arranged oppositely along the first direction X, one of which is provided with a first clamping body 2241 capable of clamping with a second clamping groove 2441 of the second cover plate 240 described below, so as to ensure the alignment stability and reliability between the second cover plate 240 and the cabinet 220. In addition, the first clamping body 2241 and the other groove wall also have a gap therebetween, which enables the second cover plate 240 to slide a certain distance along the first direction X on the cabinet 220. It can be understood that the gap can provide a certain sliding space for the sliding action of the second cover plate 240 on the cabinet 220, which is conducive to the locking and unlocking of the second cover plate 240 and the cabinet 220. Specifically, when the second cover plate 240 slides on the cabinet 220 in the direction towards the first cover plate 230 and slides to the mutual clamping of the first clamping body 2241 of the cabinet 220 and the second clamping groove 2441 of the second cover plate 240, the second cover plate 240 and the cabinet 220 have a stable abutting relationship, which is conducive to the relative fixation between the second cover plate 240 and the cabinet 220. When the second cover plate 240 slides on the cabinet 220 in the direction away from the first cover plate 230 and slides to the gradual disengagement of the first clamping body 2241 of the cabinet 220 and the second clamping groove 2441 of the second cover plate 240, the second cover plate 240 can be disengaged relative to the cabinet 220, which is conducive to assisting the second cover plate 240 to be pulled out.

[0083] In one possible implementation, as shown in Figure 3 , the cabinet 210 can further comprise a plurality of partitions 2250, each of which is arranged inside the cabinet 220. Specifically, the plurality of partitions 2250 are arranged at the first end 2211 of the bottom plate 2210, and each of the plurality of partitions 2250 extends along the first direction X and is arranged at intervals along the third direction Y. The gap region between adjacent two partitions 2250 can be used to arrange a hard disk module.

[0084] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 1 the assembly diagram of the first cover plate 230 of the electronic device 200 and the cabinet 220, Figure 5 is Figure 1 the structural diagram of the first cover plate 230 of the electronic device 200.

[0085] The first cover plate 230 covers the cabinet 220 and the plurality of partitions 2250, and the first cover plate 230 is oppositely arranged with the bottom plate 2210 of the cabinet 220 in the second direction Z. The first cover plate 230, the cabinet 220 and the plurality of partitions 2250 can cooperate to form part of the structure of the hard disk cage, and the hard disk cage can be used to set the hard disk module. Among them, the first cover plate 230 can be used as the cover plate of the cabinet 210 to cooperate with the cabinet 220 and the second cover plate 240 to form the appearance structure of the cabinet 210, and the first cover plate 230 can also be used as the cover plate of the hard disk cage to cooperate with the cabinet 220 to form the appearance structure of the hard disk cage. It should be noted that the hard disk cage is not limited to the part of the structure shown, and can also include a hard disk backplane and the like, and the embodiments of the present application do not strictly limit the actual structure of the hard disk cage.

[0086] In the embodiments of the present application, the first cover plate 230 can include a first cover plate body 2310, a first limiting portion 2320 and a first fixing portion 2330.

[0087] The first cover plate body 2310 includes two first edges 2311 oppositely arranged along the first direction X and two second edges 2312 oppositely arranged along the third direction Y, and the two second edges 2312 are connected between the two first edges 2311.

[0088] The first limiting portion 2320 is arranged on one of the two first edges 2311 close to the second cover plate 240, one end of the first limiting portion 2320 is connected with the first edge 2311, and the other end of the first limiting portion 2320 extends away from the first edge 2311, and the first limiting portion 2320 is used to cooperate with the second limiting portion 2420 of the second cover plate 240 below to realize the relative fixation of the first cover plate 230 and the second cover plate 240. The first limiting portion 2320 is provided with a first notch 2321, and the first notch 2321 can be located at the middle position of the first limiting portion 2320, and the first notch 2321 is in communication with the accommodation space W of the cabinet 220. The first notch 2321 divides the first limiting portion 2320 into two parts of a first sub-portion 2322 and a second sub-portion 2323, so as to provide a space capable of accommodating part of the locking assembly 100 by using the gap area between the first sub-portion 2322 and the second sub-portion 2323. That is, the first notch 2321 is used to accommodate part of the locking assembly 100. It should be noted that the first notch 2321 is not limited to being arranged at the middle position of the first limiting portion 2320, but can also be arranged at any position on the first limiting portion 2320 which is convenient to provide a certain space, and the embodiments of the present application do not strictly limit this.

[0089] ​The first cover plate 230 can further include a first hanging ear 2340 and a second hanging ear 2350. The first hanging ear 2340 is connected to the first sub-portion 2322 at an end close to the second sub-portion 2323, and the first hanging ear 2340 is arranged protruding relative to the first sub-portion 2322 and extends towards the box body 220. The first hanging ear 2340 is provided with a first hole 2341 penetrating the first hanging ear 2340 in the third direction Y. The second hanging ear 2350 is connected to the second sub-portion 2323 at an end close to the first sub-portion 2322, and the second hanging ear 2350 is arranged protruding relative to the second sub-portion 2323 and extends towards the box body 220. The second hanging ear 2350 is provided with a second hole 2351 penetrating the second hanging ear 2350 in the third direction Y, and the second hole 2351 is arranged corresponding to the position of the first hole 2341. By arranging the first hanging ear 2340 and the second hanging ear 2350 and arranging the first hanging ear 2340 and the second hanging ear 2350 opposite each other at a position close to the first notch 2321, the first hanging ear 2340 and the second hanging ear 2350 can cooperate to provide a suitable mounting position for the first rotating shaft 40 of the locking assembly 100 below, ensuring that the locking assembly 100 can stably connect with the first cover plate 230 through the first rotating shaft 40 of the locking assembly 100 below on the basis of normal operation.

[0090] The number of the first fixing portions 2330 is two, and the two first fixing portions 2330 are respectively arranged at the two second edges 2312. Each first fixing portion 2330 is arranged protruding relative to one second edge 2312 and extends towards the box body 220. In this arrangement, when the first cover plate 230 is closed on the box body 220, the two first fixing portions 2330 are located outside the box body 220, and the two first fixing portions 2330 can respectively abut against the box body 220 from both sides of the box body 220. At this time, the two first fixing portions 2330 can be locked on the box body 220 by fixing members 20 such as screws, bolts, etc., thereby realizing the fixed connection between the first cover plate 230 and the box body 220, and reducing the possibility of problems such as shaking of the first cover plate 230 and sliding off of the first cover plate 230 from the box body 220 to the minimum, with good reliability.

[0091] Please refer to Figure 6 , Figure 7 and Figure 8 , Figure 6 is an assembly schematic view of the box body 220 of the electronic device 200 shown in Figure 1 , Figure 7 is a structural schematic view of one angle of the second cover plate 240 of the electronic device 200 shown in Figure 1 , Figure 8 is a structural schematic view of another angle of the second cover plate 240 of the electronic device 200 shown in Figure 1 .

[0092] The second cover plate 240 is arranged opposite to the bottom plate 2210 of the case 220 in the second direction Z. The second cover plate 240 can cooperate with the first cover plate 230 to close the top of the case 220, and cooperate with the case 220 and the first cover plate 230 to form the appearance structure of the case 210. The second cover plate 240 can include a second cover plate body 2410, a second limiting portion 2420, and a second fixing portion 2430.

[0093] The second cover plate body 2410 includes two third edges 2411 arranged opposite in the first direction X and two fourth edges 2412 arranged opposite in the third direction Y, the two fourth edges 2412 being connected between the two third edges 2411. The second cover plate body 2410 further includes a first surface 2413 and a second surface 2414 arranged opposite in the second direction Z, the first surface 2413 being a surface of the second cover plate body 2410 facing the case 220, and the second surface 2414 being a surface of the second cover plate body 2410 facing away from the case 220.

[0094] The second cover plate body 2410 is provided with a mounting through hole 2415 penetrating the first surface 2413 and the second surface 2414 of the second cover plate body 2410, the mounting through hole 2415 communicating the accommodation space W inside the case 210 with the external environment of the case 210. The mounting through hole 2415 can expose part of the structure of the lock holding assembly 100, so that when a person's eyes view the mounting through hole 2415, the lock holding assembly 100 installed in the case 210 can be observed through the mounting through hole 2415, and the movement state of the lock holding assembly 100 relative to the case 210 can be observed.

[0095] In one possible implementation, as shown in Figure 7 The mounting through hole 2415 can include a first through hole 2416 and a second through hole 2417 communicating with each other, the extension direction of the first through hole 2416 intersecting the extension direction of the second through hole 2417. Exemplarily, the first through hole 2416 extends in the third direction Y, and the first through hole 2416 is rectangular. The second through hole 2417 extends in the first direction X, and the second through hole 2417 is long strip-shaped.

[0096] In the embodiments of the present application, the second limiting portion 2420 is arranged on one of the third edges 2411 of the second cover plate 240 close to the first cover plate 230, and is used to cooperate with the first limiting portion 2320 of the first cover plate 230 to realize the relative fixation of the first cover plate 230 and the second cover plate 240. Among the first limiting portion 2320 and the second limiting portion 2420, one can be a plug-in body, and the other can be a slot, and the relative fixation of the first cover plate 230 and the second cover plate 240 is realized by the corresponding plug-in of the plug-in body and the slot.

[0097] In a possible implementation manner, as shown in Figure 7 and Figure 8 The second limiting portion 2420 can include a first segment 2421, a second segment 2422 and a third segment 2423. The first segment 2421 is connected to the first surface 2413 of the first cover plate body 2310, the second segment 2422 is arranged in parallel with the first segment 2421 in the second direction Z, and the third segment 2423 is connected between the first segment 2421 and the second segment 2422. By sequentially connecting the first segment 2421, the third segment 2423 and the second segment 2422, the first segment 2421, the second segment 2422 and the third segment 2423 can cooperate to form a slot, and the slot can be plugged by the plug-in body formed by the first limiting portion 2320 of the first cover plate 230, so as to limit the relative position between the second cover plate 240 and the first cover plate 230, provide a blocking feeling after the plug-in of the second limiting portion 2420 and the first limiting portion 2320, and prevent the second cover plate 240 from continuing to move in the direction towards the first cover plate 230 to press the first cover plate 230, thereby achieving good reliability.

[0098] In the embodiments, the second limiting portion 2420 can further include a fourth segment 2424. One end of the fourth segment 2424 is connected to the end of the second segment 2422 away from the third segment 2423, and the other end of the fourth segment 2424 extends in a direction away from the first segment 2421. Thus, the fourth segment 2424 bent away from the first segment 2421 can have a wider spacing between the second segment 2422 and the first segment 2421, and can make the fourth segment 2424 and the first segment 2421 cooperate to form a trumpet-shaped flared shape, thereby providing a guiding effect for the plug-in of the first limiting portion 2320 of the first cover plate 230 and the second limiting portion 2420 of the second cover plate 240. The wider spacing can also provide a certain fault tolerance space for the first limiting portion 2320 of the first cover plate 230, so that even if the first limiting portion 2320 of the first cover plate 230 is not aligned with the second limiting portion 2420 of the second cover plate 240, it can also be slid into the second limiting portion 2420 of the second cover plate 240 under the guiding effect of the fourth segment 2424, thereby further improving the plug-in efficiency and success rate of the first limiting portion 2320 of the first cover plate 230 and the second limiting portion 2420 of the second cover plate 240.

[0099] Please continue to see Figure 7 and Figure 8 In the embodiments of the present application, the second limiting portion 2420 is provided with a second gap 2425, which can be located at the middle position of the second limiting portion 2420 and is in communication with the accommodation space W of the box body 220. The second gap 2425 separates the second limiting portion 2420 into a third sub-portion 2426 and a fourth sub-portion 2427, thereby providing a space capable of accommodating part of the locking assembly 100 by using the gap area between the third sub-portion 2426 and the fourth sub-portion 2427. That is, the second gap 2425 is used to accommodate part of the structure of the locking assembly 100. Among them, the third sub-portion 2426 of the second limiting portion 2420 can be correspondingly arranged with the first sub-portion 2322 of the first limiting portion 2320, and the fourth sub-portion 2427 of the second limiting portion 2420 can be correspondingly arranged with the second sub-portion 2323 of the first limiting portion 2320. It should be noted that the second gap 2425 is not limited to being arranged at the middle position of the second limiting portion 2420, but can also be arranged at any position on the second limiting portion 2420 which is convenient to provide a certain space, and the embodiments of the present application do not make strict restrictions on this.

[0100] The number of the second fixing portions 2430 is two, and the two second fixing portions 2430 are respectively arranged at the two fourth edges 2412. Each second fixing portion 2430 is arranged protruding relative to one fourth edge 2412 and extends towards the box body 220. Under this arrangement, when the second cover plate 240 is covered on the box body 220, the two second fixing portions 2430 are located outside the box body 220, and the two first fixing portions 2330 can respectively abut against the box body 220 from both sides of the box body 220, thereby ensuring that the second cover plate 240 and the box body 220 have a stable and reliable contact relationship.

[0101] The inner surface of the at least one second fixing portion 2430 is provided with a plurality of second clamping bodies 2440, which are arranged at intervals on the second fixing portion 2430. Each second clamping body 2440 has a gap with the second fixing portion 2430 in the third direction Y, so that one second clamping body 2440 can cooperate with the second fixing portion 2430 to form a second clamping groove 2441. The second clamping groove 2441 can be clamped with the first clamping body 2241 of the first cover plate 230 described above, so as to ensure the stability and reliability of the alignment between the second cover plate 240 and the cabinet 220. The entrance of the second clamping groove 2441 is open, so that the entrance of the second clamping groove 2441 can serve as a plug-in interface for the first clamping body 2241 and the second clamping groove 2441 to guide the plug-in of the first clamping body 2241 and the second clamping groove 2441. The outlet of the second clamping groove 2441 is closed, so that when the first clamping body 2241 is plugged into the second clamping groove 2441, a stable abutting relationship is formed between the first clamping body 2241 and the second clamping groove 2441, which is conducive to the relative fixation between the first cover plate 230 and the second cover plate 240.

[0102] In a possible implementation, referring to Figure 9 , Figure 9 is Figure 1 the assembly schematic diagram of the fan module 250 of the electronic device 200 and the cabinet 210. Among them, Figure 9 The second cover plate 240 is not shown in the figure. The electronic device 200 can also include a fan module 250, which is installed inside the cabinet 210, and the fan module 250 can dissipate heat for the electronic device 200. For example, the fan module 250 can dissipate heat for the heat generating devices such as hard disk modules, circuit boards, memories, processors, etc. in the electronic device 200, so that the electronic device 200 has good heat equalization and cooling performance, thereby improving the working stability and reliability of the electronic device 200.

[0103] Specifically, the number of fan modules 250 can be multiple, and the multiple fan modules 250 are arranged on the bottom plate 2210 in the third direction Y, and the multiple fan modules 250 are arranged at intervals with the multiple partition plates 2250 and the first cover plate 230 in the first direction X. For example, the number of fan modules 250 can be five. It should be noted that the number and type of the fan module 250 are not limited in the embodiments of the present application, and the cooling performance of the electronic device 200 can be met.

[0104] It can be understood that the cold air enters the inside of the electronic device 200 from the outside environment, carries the heat generated by the hard disk module at one end of the case 210 where the hard disk module is arranged and becomes hot air, and the hot air continues to flow and gradually flows from the first end 2211 of the bottom plate 2210 to the second end 2212 of the bottom plate 2210. Due to the arrangement of the plurality of heat dissipation devices such as the fan module 250 in the aforementioned flow path, the hot air can be discharged from the electronic device 200 after passing through the heat dissipation devices. The cold and hot air alternately circulate and circulate repeatedly to complete the uninterrupted heat exchange of the electronic device 200, so as to ensure that the electronic device 200 always has good heat dissipation performance.

[0105] Please refer to Figure 10 and Figure 11 , Figure 10 is Figure 1 a state diagram of the locking assembly 100 installed on the case 210, Figure 11 is Figure 10 an exploded diagram of the locking assembly 100 of the electronic device 200. Among them, Figure 10 the second cover plate 240 is not shown in

[0106] The locking assembly 100 is connected to the first cover plate 230 and the second cover plate 240, and the locking assembly 100 can realize the relative fixation between the second cover plate 240 and the box body 220 and the first cover plate 230, so as to make the case 210 in a closed state. The locking assembly 100 can also make the second cover plate 240 and the box body 220 and the first cover plate 230 disengage, so as to make the case 210 in an open state, which will be described below. The locking assembly 100 can include a support 10, a fixing member 20, a wrench 30, a first rotating shaft 40, a second rotating shaft 50 and a connecting structure 60.

[0107] Please refer to Figure 11 , Figure 12 and Figure 13 , Figure 12 is Figure 1 a state diagram of the support 10 of the electronic device 200, Figure 13 is Figure 1 a structural diagram of an angle of the support 10 of the electronic device 200. Among them, Figure 12 the second cover plate 240 is not shown in

[0108] One end of the support 10 is connected to the first cover plate 230, and the other end of the support 10 extends into the inside of the case 220. Specifically, the support 10 can include a first connecting end 11 and a second connecting end 12. The first connecting end 11 is an end of the support 10 connected to the first cover plate 230, and the first connecting end 11 is located in the first gap 2321 of the first limiting portion 2320. The first connecting end 11 is provided with a third hole 111 penetrating through the first connecting end 11 in the third direction Y, and the third hole 111 is provided corresponding to the first hole 2341 of the first hanging ear 2340 and the second hole 2351 of the second hanging ear 2350 in the first cover plate 230, and the third hole 111 is used for the first rotating shaft 40 to pass through.

[0109] The second connecting end 12 is an end of the support 10 away from the first cover plate 230, and the second connecting end 12 is provided with a first through slot 13 extending in the first direction X, and the first through slot 13 penetrates through the support 10 in the second direction Z, and the first through slot 13 is used for the spanner 30 to move in it. The first through slot 13 includes a first contact portion 131 and a second contact portion 132, and the second contact portion 132 and the first contact portion 131 are oppositely arranged in the first direction X, and the second contact portion 132 is closer to the first cover plate 230 relative to the first contact portion 131.

[0110] Please refer to Figure 12 and Figure 13 , one end of the first contact portion 131 is connected with the slot wall of the first through slot 13, and the other end of the first contact portion 131 protrudes towards the bottom plate 2210 of the case 210 through the first through slot 13. As shown in Figure 10 , the first contact portion 131 can contact the spanner 30. Under this arrangement, since the first contact portion 131 has a certain protruding length relative to the support 10, the first contact portion 131 can have a larger contact area with the spanner 30 due to the longer extension length, which is beneficial to improve the contact stability and reliability of the first contact portion 131 and the spanner 30. When the spanner 30 moves in the first through slot 13 to contact the first contact portion 131, the first contact portion 131 can provide powerful support to the spanner 30 as the first support point of the support 10, and through the mutual resistance between the first contact portion 131 and the spanner 30, the case 210 can be kept in a closed state.

[0111] In a possible implementation, the surface of the first contact portion 131 that contacts the wrench 30 is curved. In this arrangement, the surface of the first contact portion 131 that contacts the wrench 30 can be a smooth curve, which helps to reduce the problem of wear of the wrench 30 caused by the first contact portion 131 having corners. The surface of the first contact portion 131 can also be curved to match the surface profile of the wrench 30, which helps to increase the contact area between the first contact portion 131 and the wrench 30, and improve the contact stability and reliability of the first contact portion 131 and the wrench 30.

[0112] Please refer to Figure 12 and Figure 13 In the embodiments of the present application, one end of the second contact portion 132 is connected to the slot wall of the first slot 13, and the other end of the second contact portion 132 protrudes towards the bottom plate 2210 of the case 210 through the first slot 13. Please refer to Figure 14 , Figure 14 is Figure 1 the schematic diagram of another state of the locking assembly 100 shown in FIG. 10, in which Figure 14 The second cover plate 240 is not shown. The second contact portion 132 can contact the wrench 30. In this arrangement, since the second contact portion 132 has a certain protruding length relative to the support 10, the second contact portion 132 can have a larger contact area with the wrench 30 due to the longer extension length, which helps to improve the contact stability and reliability of the second contact portion 132 and the wrench 30. When the wrench 30 moves in the first slot 13 to contact the second contact portion 132, the second contact portion 132 can serve as a second support point of the support 10 to provide strong support to the wrench 30, and the action force and the reaction force applied between the second contact portion 132 and the wrench 30 can cause the case 210 to switch from the closed state to the open state.

[0113] In a possible implementation, the surface of the second contact portion 132 that contacts the wrench 30 is curved. In this arrangement, the surface of the second contact portion 132 that contacts the wrench 30 can be a smooth curve, which helps to reduce the problem of wear of the wrench 30 caused by the second contact portion 132 having corners. The surface of the second contact portion 132 can also be curved to match the surface profile of the wrench 30, which helps to increase the contact area between the second contact portion 132 and the wrench 30, and improve the contact stability and reliability of the second contact portion 132 and the wrench 30.

[0114] Please refer to Figure 11 and Figure 12In the embodiments of the present application, the first rotating shaft 40 is arranged through the first connecting end 11 of the support 10, and the first rotating shaft 40 is also connected to the first hanging ear 2340 and the second hanging ear 2350 of the first cover plate 230. The first rotating shaft 40 is arranged through the first hole 2341 of the first hanging ear 2340, the third hole 111 of the first connecting end 11 and the second hole 2351 of the second hanging ear 2350 in sequence, so that the first cover plate 230 and the support 10 are connected in series, and the support 10 is connected to the first cover plate 230 through the first rotating shaft 40. In addition, the support 10 can rotate relative to the first cover plate 230 about the center line of the first rotating shaft 40, so that the support 10 can be rotationally connected to the first cover plate 230 through the first rotating shaft 40.

[0115] Please refer to Figure 15 , Figure 15 is Figure 1 another state diagram of the support 10 of the electronic device 200 shown in FIG. 2. In the diagram, Figure 15 The second cover plate 240 is not shown in the diagram. The support 10 can be rotated relative to the first cover plate 230 to be arranged obliquely to the first cover plate 230, so that most of the support 10 is located above the first cover plate 230. It can be understood that the first cover plate 230, the box body 220 and the plurality of partition plates 2250 can cooperate to form part of the hard disk cage for accommodating the hard disk module. When the plurality of partition plates 2250 are assembled in place with the box body 220 and the first cover plate 230, the hard disk back plate (not shown in the diagram) can be assembled on the plurality of partition plates 2250 in the direction opposite to the first direction X. Since the support 10 can be rotated to be located above the first cover plate 230, the support 10 does not block the gap region between the first cover plate 230 and the fan module 250, and the hard disk back plate (not shown in the diagram) can be conveniently and quickly installed to the side of the first cover plate 230 and the plurality of partition plates 2250 close to the fan module 250 in the direction opposite to the first direction X, so that the assembly of the hard disk back plate is not blocked by the support 10, the assembly process is simple, and the assembly efficiency of the electronic device 200 is improved.

[0116] Please refer to Figure 12 again, the support 10 can also be rotated relative to the first cover plate 230 to be arranged parallel to the first cover plate 230, so that the support 10 is located in the gap region between the first cover plate 230 and the fan module 250. At this time, the support 10 is rotated in place, and the support 10 can support the movement of the dynamic part (such as the wrench 30) in the locking assembly 100 as a static part in the locking assembly 100.

[0117] The support 10 can be connected to the first cover plate 230 near one side of the second cover plate 240 through the first rotating shaft 40. When the support 10 is rotated relative to the first cover plate 230 to be located in the cabinet 210, the support 10 is located in the gap area between the fan module 250 and the first cover plate 230, and the maximum distance between the support 10 and the second cover plate 240 in the second direction Z is less than the minimum distance between the support 10 and the bottom plate 2210.

[0118] It can be understood that, since the cold air in the external environment enters the cabinet 210 from the front end of the cabinet 210 (i.e., the side of the cabinet 210 where the first cover plate 230 is located), the cold air becomes hot air after carrying the heat of the heat generating device in the cabinet 210 and then exits from the rear end of the cabinet 210 (i.e., the side of the cabinet 210 where the second cover plate 240 is located away from the first cover plate 230). Since the support 10 is located in the gap area between the fan module 250 and the first cover plate 230, the support 10 is actually located at the front end of the fan module 250. Moreover, the maximum distance between the support 10 and the second cover plate 240 of the cabinet 210 is less than the minimum distance between the support 10 and the bottom plate 2210 of the cabinet 210, so that the support 10 is closer to the second cover plate 240 of the cabinet 210 relative to the bottom plate 2210 of the cabinet 210. That is, the support 10 is arranged on the top side of the cabinet 210.

[0119] On the one hand, compared with the prior art in which the part of the upper cover lock is arranged on the bottom plate of the cabinet, the fan module needs to avoid the upper cover lock to avoid being largely blocked by the upper cover lock. In the embodiment of the present application, the support 10 is arranged on the top side of the cabinet 210. The space occupied by the electronic device 200 due to the avoidance of the upper cover lock can be released, and the space is released to arrange more fan modules 250, so that the number of fan modules 250 can be increased on the basis of ensuring the good working performance of the electronic device 200, thereby further improving the heat dissipation performance of the electronic device 200. On the other hand, arranging the support 10 on the top side of the cabinet 210 can make the air inlet channel of the fan module 250 permeable, can minimize the space occupied by the fan module 250 due to the arrangement of the upper cover lock and the adverse effects on the selection of the fan module 250, and can minimize the possibility of the problem that the air resistance of the whole system is increased and the heat dissipation specification of the whole machine is difficult to improve due to the blocking of the fan module 250 by the upper cover lock, thereby improving the heat dissipation capacity of the whole machine.

[0120] Please refer to Figure 16 , Figure 17 and Figure 18 , Figure 16 is Figure 1 the structural schematic view of the angle between the second cover plate 240 and the fixing member 20 shown in Figure 17 isFigure 1 Fig. 6 is a structural schematic view of another angle of the second cover plate 240 assembled with the fixing member 20, Figure 18 is Figure 1 Fig. 5 is a structural schematic view of the fixing member 20 of the electronic device 200. In this figure, Figure 16 is a top view of the second cover plate 240 of the electronic device 200, Figure 17 is a bottom view of the second cover plate 240 of the electronic device 200.

[0121] The fixing member 20 is fixedly connected with the second cover plate 240, and part of the structure of the fixing member 20 can be exposed through the mounting through hole 2415. The fixing member 20 includes a box body 21 and a plurality of folded edge structures 22.

[0122] The box body 21 has a receiving groove 211 and a through groove 212. One end of the box body 21 is open to form a slot of the receiving groove 211, the receiving groove 211 is in communication with the mounting through hole 2415 of the first cover plate 230, and the receiving groove 211 can accommodate part of the structure of the wrench 30. The through groove 212 is arranged at the other end of the box body 21, the through groove 212 penetrates the box body 21 along the thickness direction of the box body 21, and the through groove 212 is in communication with the receiving space W of the box body 220. It should be understood that the through groove 212 can also be regarded as a groove structure arranged on the groove bottom wall of the receiving groove 211 and penetrating the box body 21. That is, in the second direction Z, the through groove 212 and the receiving groove 211 are arranged in sequence, so that the box body 21 can be in communication with the receiving space W in the box body 220 and the external environment outside the box body 220.

[0123] The plurality of folded edge structures 22 are bent and connected to one end of the box body 21, and the plurality of folded edge structures 22 are arranged along the circumferential direction of the box body 21 and arranged at the periphery of the box body 21. The plurality of folded edge structures 22 are also fixedly connected to the first surface 2413 of the second cover plate 240, so as to realize the fixation of the box body 21 and the second cover plate 240 through the fixation between the plurality of folded edge structures 22 and the second cover plate 240. When the plurality of folded edge structures 22 are fixed to the first surface 2413 of the second cover plate 240, the first through hole 2416 of the mounting through hole 2415 can expose part of the structure of the box body 21 of the fixing member 20. It can be understood that by arranging the plurality of folded edge structures 22 at the periphery of the box body 21, sufficient contact area can be obtained between the box body 21 and the second cover plate 240 without occupying the internal space of the box body 21, so that the fixing member 20 and the second cover plate 240 can have a stable and reliable connection relationship.

[0124] Exemplarily, as Figure 18As shown, the plurality of folding structures 22 can include a first folding structure 221, a second folding structure 222, a third folding structure 223, and a fourth folding structure 224, which are sequentially arranged on the four edges of one end of the box body 21. The third folding structure 223 and the first folding structure 221 are oppositely arranged in the first direction X, and the second folding structure 222 and the fourth folding structure 224 are oppositely arranged in the third direction Y. The first folding structure 221 is provided with a third notch 225, which is in communication with the accommodation groove 211. The third notch 225 can be matched with the accommodation groove 211 to jointly accommodate the wrench 30.

[0125] Please refer to Figure 19 , Figure 19 is Figure 1 the state diagram of the support 10 and the fixing member 20 when the lock holding assembly 100 shown in is installed in the case 210. Among them, Figure 19 The second cover plate 240 is not shown in the embodiment of the present application. When the support 10 is rotated relative to the first cover plate 230 to be arranged in parallel with the first cover plate 230, so that the support 10 is located in the gap region between the first cover plate 230 and the fan module 250. The fixing member 20 is fixed on the second cover plate 240 and is also located above the support 10. Specifically, the projection of the fixing member 20 on the support 10 is located in the region between the first connecting end 11 and the first through groove 13. That is, the setting position of the fixing member 20 corresponds to the region between the first connecting end 11 and the first through groove 13 on the support 10. With this setting, the accommodation or disengagement action of the wrench 30 in the fixing member 20 can be realized through the movement of the wrench 30 relative to the support 10 without affecting the movement of the wrench 30 in the first through groove 13.

[0126] Please refer to Figure 16 and Figure 17 , the connecting structure 60 can include a first part 61 and a second part 62. The first part 61 is connected to the first surface 2413 of the first cover plate 230, and the first part 61 is arranged close to the second through hole 2417 of the mounting through hole 2415. One end of the second part 62 is connected to the first part 61 by bending, and the other end of the second part 62 extends in the opposite direction of the second direction Z. A second rotating shaft 50 is provided on the second part 62, and the second rotating shaft 50 is used to connect the wrench 30.

[0127] Please refer to Figure 10 , Figure 14 , Figure 20 and Figure 21 , Figure 20 is Figure 10 the state diagram of the lock holding assembly 100 of the electronic device 200 and the second cover plate 240 shown in Figure 21 is Figure 1Another state diagram of the locking assembly 100 of the electronic device 200 and the second cover plate 240.

[0128] The spanner 30 can be connected to the first surface 2413 of the second cover plate 240 through the connecting structure 60 connected to the first surface 2413 of the second cover plate 240. When the spanner 30 is connected to the first surface 2413 of the second cover plate 240, the spanner 30 is exposed by the mounting through hole 2415. The spanner 30 can pass through the mounting through hole 2415 and the first through slot 13. The spanner 30 can rotate relative to the second cover plate 240 through the mounting through hole 2415 to engage with the receiving groove 211 of the fixing member 20 to drive the second cover plate 240 to be locked with the case 220 and the first cover plate 230. The spanner 30 can also rotate relative to the second cover plate 240 through the mounting through hole 2415 to disengage from the receiving groove 211 of the fixing member 20 to drive the second cover plate 240 to be unlocked with the case 220 and the first cover plate 230.

[0129] In a possible application scenario, as shown in Figure 10 and Figure 20 The spanner 30 can be rotated to contact an end (i.e., the first contact portion 131) of the first through slot 13 arranged along the first direction X, so that the spanner 30 engages with the receiving groove 211 of the fixing member 20 to drive the second cover plate 240 to be locked with the case 220 and the first cover plate 230, and the case 210 is in a closed state.

[0130] In another possible application scenario, as shown in Figure 14 and Figure 21 The spanner 30 can be rotated to contact another end (i.e., the second contact portion 132) of the first through slot 13 arranged along the first direction X, so that the spanner 30 disengages from the receiving groove 211 of the fixing member 20 to drive the second cover plate 240 to be unlocked with the case 220 and the first cover plate 230, and the case 220 is in an open state.

[0131] It should be noted that when the spanner 30 disengages from the receiving groove 211 of the fixing member 20 to drive the second cover plate 240 to be unlocked with the case 220 and the first cover plate 230, and the case 220 is in an open state, the spanner 30 can also not contact the other end (i.e., the second contact portion 132) of the first through slot 13 arranged along the first direction X, and the embodiments of the present application do not make strict restrictions thereon.

[0132] It can be understood that when the internal components of the electronic device 200 need to be maintained, the first cover plate 230 and the box body 220 can be static components in the case 210, and the second cover plate 240 can be a dynamic component in the case 210. The second cover plate 240 can be unlocked relative to the first cover plate 230 and the box body 220 by the locking assembly 100 to facilitate the subsequent disengagement of the second cover plate 240 from the box body 220 and the first cover plate 230, so that the internal components of the case 210 can be disassembled, repaired, replaced, and the like. When the internal components of the electronic device 200 do not need to be maintained, the second cover plate 240 can be locked relative to the first cover plate 230 and the box body 220 by the locking assembly 100, so that the first cover plate 230 can be tightly connected with the box body 220 and the first cover plate 230, thereby ensuring the overall strength of the case 210.

[0133] By providing the support member 10 and connecting the support member 10 to the first cover plate 230, the position of the first cover plate 230 relative to the case 210 can be substantially unchanged, and the support member 10 can support the movement of the dynamic component wrench 30 in the locking assembly 100 as a static component in the locking assembly 100. Because the connection strength between the first cover plate 230 and the case 210 is strong, directly connecting the support member 10 to the first cover plate 230 can also provide good cooperation between the support member 10 and the first cover plate 230, effectively avoiding the problems of deforming the case base during the locking and unlocking operations of the upper cover, adversely affecting the subsequent fan module 250, and the like, thereby improving the overall strength of the case 210 during the locking and unlocking operations of the second cover plate 240 relative to the box body 220 and the first cover plate 230.

[0134] By providing the wrench 30 and connecting the wrench 30 to the second cover plate 240 and the first through slot 13 of the support member 10, the wrench 30 can be in contact with the opposite ends of the first through slot 13 by rotating relative to the second cover plate 240. One end of the first through slot 13 can serve as a rotating support point on the support member 10, and when the wrench 30 rotates to contact the one end, a force point is provided for the wrench 30, thereby assisting the wrench 30 to keep the second cover plate 240 locked with the box body 220 and the first cover plate 230. The other end of the first through slot 13 can also serve as another rotating support point on the support member 10, and when the wrench 30 rotates to contact the other end, a force point is provided for the wrench 30, thereby assisting the wrench 30 to unlock the second cover plate 240 relative to the box body 220 and the first cover plate 230.

[0135] In addition, since the support 10 is connected to the first cover plate 230 and the wrench 30 is connected to the second cover plate 240, the locking assembly 100 is located on the top side of the cabinet 210 as a whole. In the prior art, the upper cover lock is distributed on the bottom and top of the cabinet, and the upper cover lock seriously affects the air inlet in the cabinet, thereby causing the problem that the air resistance of the whole machine system is increased and the heat dissipation specification of the whole machine is difficult to improve. In the technical solution of the present application, the locking assembly 100 is concentratedly distributed on the top of the cabinet 210, so that the air inlet channel in the cabinet 210 is permeable, and the adverse effects of the air fan module 250 selection and arrangement in the equipment caused by the excessive occupation of the air inlet channel by the upper cover lock can be minimized, which is beneficial to improving the heat dissipation capacity of the whole machine.

[0136] Based on the above description, it should be understood that through the locking and unlocking actions of the locking assembly 100, the opening state, the closing state and the intermediate state between the opening state and the closing state of the cabinet 210 can be realized, which will be described below.

[0137] Please refer to Figure 10 and Figure 14 , the wrench 30 can include a key 31 and a handle 32. The handle 32 is rotationally connected with the second cover plate 240. One end of the handle 32 passes through the first through slot 13 of the support 10, and the other end of the handle 32 is connected with the key 31. The handle 32 can rotate relative to the second cover plate 240 to make the key 36 engaged with the receiving slot 211 of the fixing member 20, or to make the key 36 disengaged from the receiving slot 211 of the fixing member 20.

[0138] Specifically, as shown in Figure 14 and Figure 21 , when the components in the cabinet 210 need to be maintained, the second cover plate 240 needs to be removed from the cabinet body 220 and the first cover plate 230, the key 31 is rotated and pulled upward, so that the handle 32 can rotate clockwise around the rotation center of the handle 32, thereby making the key 31 connected with the handle 32 disengaged from the receiving slot 211 of the fixing member 20, so as to unlock the second cover plate 240 from the cabinet body 220 and the first cover plate 230, and assist the second cover plate 240 to be pulled out relative to the cabinet body 220 and the first cover plate 230. As shown in Figure 10 and Figure 19 , when the components in the cabinet 210 are completed, the key 31 is rotated and pressed downward, so that the handle 32 can rotate counterclockwise around the rotation center of the handle 32, thereby making the key 31 connected with the handle 32 engaged with the receiving slot 211 of the fixing member 20, so as to lock the second cover plate 240 with the cabinet body 220 and the first cover plate 230.

[0139] It can be understood that, as shown in Figure 10 and Figure 20 ​​​​​​​​As shown, when the chassis 210 is in the closed state, the dial button 31 is engaged with the receiving slot 211, and the dial button 31 and part of the handle 32 can be flush with the second cover 240. At this time, the handle 32 contacts the first contact portion 131, and the handle 32 presses the first contact portion 131 backward, so that the first contact portion 131 exerts a forward force on the handle 32, thereby helping the second cover 240 to be locked with the box body 220 and the first cover 230. Figure 14 and Figure 21 As shown, when the case 210 is switched from the closed state to the open state, the dial button 31 is disengaged from the receiving slot 211, and the dial button 31 and a portion of the handle 32 can protrude relative to the second cover 240. At this time, the handle 32 contacts the second contact portion 132, and the handle 32 presses the second contact portion 132 forward, so that the second contact portion 132 exerts a backward force on the handle 32, thereby helping to unlock the second cover 240 from the case body 220 and the first cover 230.

[0140] Please refer to Figure 10 and Figure 22 , Figure 22 yes Figure 10 The figure shows an exploded view of the wrench 30 of the locking assembly 100. The handle 32 can include a handle body 33 and a handle fixing portion 34. The handle body 33 is the portion of the handle 32 that is connected to the second cover plate 240 and abuts against the first contact portion 131 and the second contact portion 132 of the support member 10. The handle fixing portion 34 is the portion of the handle 32 that is connected to the dial key 31.

[0141] Specifically, one end of the handle body 33 is connected to the handle fixing portion 34, and the other end of the handle body 33 extends through the first through-slot 13 of the support member 10. The handle body 33 is connected to one end of the second rotating shaft 50 extending from the connecting structure 60. The handle body 33 can be rotatably connected to the connecting structure 60 via the second rotating shaft 50. Because the connecting structure 60 is fixedly connected to the second cover plate 240, the handle body 33 can be rotatably connected to the second cover plate 240, thereby achieving a rotatable connection between the wrench 30 and the second cover plate 240.

[0142] like Figure 14 and Figure 22 As shown, when the handle body 33 rotates clockwise around the center line of the second rotation axis 50, the handle body 33 can abut against the second contact portion 132 of the first through groove 13. Figure 10 and Figure 22 As shown, when the handle body 33 rotates counterclockwise around the center line of the second rotation axis 50 , the handle body 33 may abut against the first contact portion 131 of the first through slot 13 .

[0143] Please refer to Figure 10 and Figure 22One end of the handle fixing portion 34 is connected to one end of the handle body 33, and the other end of the handle fixing portion 34 extends away from the handle body 33. The handle fixing portion 34 is arranged at an angle with the handle body 33, that is, the handle fixing portion 34 is arranged protruding in the opposite direction of the third direction Y relative to the handle body 33. The handle fixing portion 34 is provided with a second through slot 341 penetrating the handle fixing portion 34 along the thickness direction of the handle fixing portion 34, and the second through slot 341 is used to cooperate with the key 31.

[0144] In the embodiments of the present application, the key 31 can include a base 35, a key 36, and an elastic member 37. The handle 32 is embedded in the base 35, the key 36 covers one side of the base 35 where the handle 32 is arranged, the key 36 is in sliding connection with the base 35, and the elastic member 37 is elastically supported between the base 35 and the key 36.

[0145] Please refer to Figure 22 and Figure 23 , Figure 23 is Figure 22 the structural schematic view of another angle of the key 36 shown in FIG. 6. The key 36 can include a key body 361, a sliding body 362, and a key clamping portion 363.

[0146] The number of the sliding body 362 can be two, and the two sliding bodies 362 are respectively located on opposite sides of the key body 361 along the first direction X, and the two sliding bodies 362 are arranged at intervals in the first direction X. The sliding body 362 can slide on the base 35 along the third direction Y and the opposite direction of the third direction Y, so that the key 36 as a whole can slide along the third direction Y and the opposite direction of the third direction Y relative to the base 35.

[0147] The key clamping portion 363 is located in the gap region between the two sliding bodies 362, one end of the key clamping portion 363 is connected to the key body 361, and the other end of the key clamping portion 363 extends away from the key body 361. The key clamping portion 363 is provided with a blind hole 364 for accommodating part of the elastic member 37. Exemplarily, the other end of the key clamping portion 363 can be a clamping hook. In addition, the key clamping portion 363 can be made of plastic material, so that the wrench 30 can be optimized to be composed of metal and plastic structures, which is beneficial to reduce the cost of the wrench 30, and thus reduces the cost of the lock holding assembly 100.

[0148] Please refer to Figure 22 and Figure 24 , Figure 24 is Figure 22Another angle structural schematic view of the base 35 is shown. The base 35 comprises a carrier plate 351, an inner layer baffle 352 and an outer layer baffle 353. The carrier plate 351 is provided with a third through slot 354 penetrating through the carrier plate 351 along the thickness direction of the carrier plate 351, and the third through slot 354 is communicated with the accommodation space W in the box body 220 and the second through slot 341 of the handle 32, so that the key clamping portion 363 of the key 36 can pass through the second through slot 341 of the handle 32 and the third through slot 354 of the base 35 in sequence, and the key 36, the handle 32 and the base 35 have a reliable connection relationship.

[0149] The inner layer baffle 352 is arranged on the carrier plate 351 and is arranged along the circumferential direction of the third through slot 354. The inner layer baffle 352 is provided with a protruding portion 355 located in the space surrounded by the inner layer baffle 352 and / or in the third through slot 354. The protruding portion 355 is arranged corresponding to the blind hole 364 of the key clamping body of the key 36, and the protruding portion 355 is used to provide a mounting position of the elastic member 37.

[0150] The outer layer baffle 353 is arranged on the carrier plate 351 and is located at the periphery of the inner layer baffle 352. The gap region between the outer layer baffle 353 and the inner layer baffle 352 forms a mounting groove 356 for accommodating the handle fixing portion 34 of the handle 32. In this arrangement, when the base 35, the handle 32 and the key 36 are arranged in sequence, one side of the handle fixing portion 34 is limited by the base 35, and the other side of the handle fixing portion 34 is limited by the key 36, so that the handle 32 can be clamped between the base 35 and the key 36, and the movement of the handle 32 is limited by the cooperation of the key 36 and the base 35, that is, the handle 32 is fixed by the cooperation of the key 36 and the base 35. The movement can refer to the movement of the handle 32 in one or more of the first direction X, the second direction Z, the third direction Y, the opposite direction of the first direction X, the opposite direction of the second direction Z and the opposite direction of the third direction Y.

[0151] Specifically, when the handle fixing portion 34 of the handle 32 is embedded in the mounting groove 356, the groove wall of the second through slot 341 of the handle fixing portion 34 can be in contact with the inner layer baffle 352, and the outer periphery of the handle fixing portion 34 can be in contact with the outer layer baffle 353, so that the handle fixing portion 34 is nested in the base 35, and the handle 32 and the base 35 have good installation stability and reliability.

[0152] Please refer to Figure 22 and Figure 24The height of the inner baffle 352 is less than that of the outer baffle 353. That is, in the second direction Z, the distance between the end of the inner baffle 352 away from the carrier plate 351 and the carrier plate 351 is less than the distance between the end of the outer baffle 353 away from the carrier plate 351 and the carrier plate 351, thereby creating a height difference between the inner baffle 352 and the outer baffle 353. This allows the inner baffle 352 and the outer baffle 353 to cooperate to form a slide rail 357. The slide rail 357 can be mounted on the slider 362 of the button 36, thereby enabling the button 36 to slide on the base 35 along the third direction Y and the direction opposite to the third direction Y.

[0153] In the embodiment of the present application, the elastic member 37 is mounted on the protrusion 355 of the base 35. The elastic member 37 elastically abuts between the inner baffle 352 of the base 35 and the bottom wall of the blind hole 364 of the button 36, thereby creating a tensioning force between the base 35 and the button 36. It is understood that when the button 36 is moved and slid in the direction opposite to the third direction Y, the elastic member 37 is elastically deformed by the force and enters a compressed state. When the force moving the button 36 is removed, the presence of the elastic member 37 provides a restoring force for the button 36, driving the button retaining portion 363 to gradually move away from the protrusion 355, thereby restoring the button 36.

[0154] Please refer to Figure 10 and Figure 25 , Figure 25 For the Figure 10 The cross-sectional view taken along the cutting line AA is shown. When the second cover 240 is locked to the first cover 230 and the housing 220, that is, when the chassis 210 is in the closed state, the end of the button retaining portion 363 away from the button body 361 passes through the second through-slot 341 of the handle fixing portion 34, the third through-slot 354 of the carrier plate 351, the receiving slot 211 of the fixing member 20, and the through-slot 212 of the fixing member 20 in sequence. The end of the button retaining portion 363 away from the button body 361 extends out of the fixing member 20 and is retained by the fixing member 20, thereby ensuring the reliability and tightness of the locking between the second cover 240 and the chassis 210 and the first cover 230.

[0155] When it is necessary to open the second cover 240 and unlock the second cover 240 from the first cover 230 and the box body 220, the button 36 is toggled to slide in a direction opposite to the third direction Y. When the button retaining portion 363 moves within the receiving groove 211 and the through-groove 212 of the fixing member 20 until it is no longer in contact with the through-groove 212 of the fixing member 20, the button body 361 is lifted upward to disengage the button retaining portion 363 from the receiving groove 211 and the through-groove 212 of the fixing member 20, thereby moving the wrench 30 away from the fixing member 20. The second cover 240 can then be removed by rotating the wrench 30.

[0156] In one possible implementation, please refer to Figure 26 , Figure 26 is along Figure 10 the cross-sectional view of the electronic device 200 shown in FIG. 10. When the cabinet 210 is in the closed state, the key clamping portion 363 away from the end of the key body 361 can also be in contact with the support 10, so that the support 10 can provide a certain supporting force for the key clamping portion 363, and ensure that the position of the key clamping portion 363 does not change during the movement of the electronic device 200.

[0157] The above describes the embodiments of the present application in detail, and the principles and implementation manners of the present application are described by applying specific examples. The above embodiment description is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range will be changed, and the above description should not be understood as a limitation of the present application.
