Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background Art

[0002] With the rise of big data, cloud computing, and AI (artificial intelligence), the demand for electronic devices such as servers and supercomputers is growing. To improve their competitiveness, electronic devices need to increase computing speed and storage capacity by increasing configuration density. However, the increase in computing speed and storage capacity can easily lead to increasing power consumption of electronic devices. Currently, since part of the structure of the upper cover lock of electronic devices is installed on the chassis base of the electronic device, it can easily occupy too much internal space of the chassis, resulting in a decrease in the rationality of the space utilization within the chassis. Summary of the Invention

[0003] The embodiments of the present application provide an electronic device that can make the arrangement of the upper cover lock more compact, reduce the internal space of the device occupied by the upper cover lock, and utilize the device space released by the upper cover lock to ensure the reasonable arrangement of other components in the electronic device, thereby effectively improving the space utilization rate inside the electronic device.

[0004] An electronic device provided in an embodiment of the present application includes:

[0005] A chassis, comprising a box body, a first cover plate and a second cover plate, wherein the first cover plate and the second cover plate are covered on the box body, and the first cover plate and the second cover plate are arranged along a first direction, where the first direction is the length direction of the electronic device; and

[0006] The locking assembly includes a support member, a rotating shaft mechanism, a connecting swing arm and a handle;

[0007] The support member is connected to the first cover plate, and the support member is provided with a slide groove, and the slide groove extends along a second direction, and the second direction is a width direction of the electronic device;

[0008] The rotating shaft mechanism is provided through the second cover plate, and the center line of the rotating shaft mechanism is parallel to the third direction, and the third direction is the height direction of the electronic device;

[0009] One end of the connecting swing arm is connected to the rotating shaft mechanism, and the other end of the connecting swing arm is inserted into the sliding groove;

[0010] The handle is connected to the rotating shaft mechanism, and the handle can rotate around the center line of the rotating shaft mechanism, driving the other end of the connecting swing arm to slide in the sliding groove, so that the second cover plate moves relative to the first cover plate and the box body along the first direction, and is fixedly connected to or detached from the box body.

[0011] It is understood that when the internal components of the electronic device need to be maintained, the first cover and the housing can serve as static components of the chassis, and the second cover can serve as a dynamic component of the chassis. The second cover can be unlocked relative to the first cover and the housing via the latch assembly, allowing the second cover to be subsequently removed from the housing and the first cover, thereby allowing staff to disassemble, repair, replace, etc. the internal components of the chassis. When the internal components of the electronic device have finished maintenance or no longer need maintenance, the second cover can be locked relative to the first cover and the housing via the latch assembly, so that the first cover can be tightly connected to the housing and the second cover, ensuring the overall strength of the chassis.

[0012] By providing a support member and connecting the support member to the first cover plate, the position of the first cover plate relative to the chassis will basically not change, and the support member can serve as a static component in the lock assembly to support the movement of the dynamic components of the lock assembly, the handle and the connecting swing arm. In addition, since the connection strength between the first cover plate and the chassis is relatively strong, directly connecting the support member to the first cover plate can also ensure good matching performance between the support member and the first cover plate. This can effectively avoid the existing technology of providing the supporting structure of the upper cover lock at the chassis base, which causes the upper cover to pull the chassis base during locking and unlocking operations, causing deformation of the chassis base and adversely affecting the subsequent insertion of the fan module. This is beneficial for ensuring that the overall strength of the chassis is not affected during the process of fixed connection or detachment of the second cover plate from the case body, and has good reliability.

[0013] In addition, because the support member is connected to the first cover plate and the handle is connected to the second cover plate, the entire lock assembly is located on the top side of the chassis. Compared with the prior art where the upper cover locks are distributed at the bottom and top of the chassis, the upper cover locks occupy too much internal space of the device, resulting in a reduction in the space occupied by other components in the electronic device and the number of components that can be arranged. In the technical solution of the present application, the lock assembly is concentrated and distributed at the top of the chassis, making the layout of the upper cover locks more compact. The device space ceded by the upper cover locks can be used to increase the layout space and the number of components that can be arranged in the electronic device, which is conducive to achieving a reasonable arrangement of components inside the electronic device and improving the space utilization rate inside the electronic device.

[0014] In one possible embodiment, the connecting swing arm includes a swing arm body and a sliding body, the swing arm body includes a first end and a second end, the rotating shaft mechanism is fixedly connected to the second end, one end of the sliding body is fixedly connected to the first end, the sliding body extends toward the bottom plate of the box body, and the other end of the sliding body is passed through the slide groove.

[0015] In a possible implementation, the sliding groove includes a first side wall and a second side wall, the second side wall is arranged opposite to the first side wall in the first direction, and the second side wall is closer to the rotating shaft mechanism relative to the first side wall;

[0016] When the second cover plate is fixedly connected to the box body, the sliding body abuts against the first side wall.

[0017] In a possible implementation, the sliding groove includes a first side wall and a second side wall, the second side wall is arranged opposite to the first side wall in the first direction, and the second side wall is closer to the rotating shaft mechanism relative to the first side wall;

[0018] When the second cover plate is separated from the box body, the sliding body abuts against the second side wall, or when the second cover plate is separated from the box body, the sliding body is located between the first side wall and the second side wall.

[0019] Specifically, when the handle is engaged with the second cover, the sliding body can move within the chute until it abuts against the first side wall, thereby locking the second cover to the first cover and the chassis. When the handle is disengaged from the second cover, the sliding body can move within the chute until it abuts against the second side wall, thereby unlocking the second cover from the first cover and the chassis. Alternatively, the sliding body can move within the chute until it is located between the first side wall and the second side wall, thereby unlocking the second cover from the first cover and the chassis. It should be noted that the second cover can also be unlocked from the first cover and the chassis when the sliding body is at any position between the first side wall and the second side wall in the chute, and this is not strictly limited in this embodiment.

[0020] In one possible embodiment, the second cover plate is provided with a first boss, the first boss protruding toward the bottom plate of the case, a first receiving cavity is provided in the first boss, the first receiving cavity has a first opening, the first opening is located on a surface of the second cover plate facing away from the case, and the first boss is further provided with a first mounting hole, the first mounting hole communicating with the first receiving cavity and the interior of the chassis;

[0021] One end of the rotating shaft mechanism is located in the first receiving cavity, and the other end of the rotating shaft mechanism passes through the first mounting hole. The handle is connected to the end of the rotating shaft mechanism located in the first receiving cavity, and at least a portion of the handle is located in the first receiving cavity.

[0022] In a possible embodiment, a through slot and a second mounting hole are provided at the second end of the swing arm body, the second mounting hole is spaced apart from the through slot, and the rotating shaft mechanism includes a shaft seat, a first shaft body, and a first elastic member;

[0023] The axle seat is passed through the first mounting hole of the second cover plate and the second mounting hole of the connecting swing arm, the first shaft body extends into the axle seat through the second mounting hole and is fixedly connected to the axle seat, the first elastic member is wound around the first shaft body, one end of the first elastic member is fixed to the second end of the connecting swing arm, and the other end of the first elastic member passes through the through slot.

[0024] On the one hand, the provision of the first elastic member can limit the rotation angle of the rotating shaft mechanism, preventing excessive rotation of the rotating shaft mechanism and thus reducing the reliability of the locking assembly. On the other hand, the provision of the first elastic member can enable the rotating shaft mechanism to perform multiple torsional movements due to the elastic return effect of the first elastic member, thereby improving reliability. For example, the first elastic member can be a torsion spring.

[0025] In a possible embodiment, the shaft seat includes a carrier, a first connecting portion and a second connecting portion, wherein the first connecting portion and the second connecting portion are respectively connected to opposite sides of the carrier;

[0026] The carrier and the first connecting part are located in the first receiving cavity, the first connecting part is connected to the handle, the second connecting part passes through the first mounting hole, and the second connecting part is fixedly connected to the second end of the connecting swing arm. The connecting swing arm can be driven by the second connecting part to rotate around the center line of the rotating shaft mechanism.

[0027] With this arrangement, when the shaft seat is installed in the first mounting hole of the first receiving cavity, the carrier acts as a stop, thereby retaining the first connecting portion of the shaft seat within the first receiving cavity, preventing the first connecting portion of the shaft seat from passing through the first mounting hole and extending into the chassis. The second cover plate and the connecting swing arm cooperate to accommodate and secure the shaft seat, ensuring good connection stability and reliability between the shaft seat, the second cover plate, and the connecting swing arm.

[0028] This arrangement allows the shaft seat to be fixedly connected to the connecting swing arm, allowing the shaft seat to move in conjunction with the connecting swing arm due to the connection between the two. Specifically, when the shaft seat rotates counterclockwise around the centerline of the rotating shaft mechanism, the second end of the connecting swing arm can be driven by the second connecting portion to rotate counterclockwise around the centerline of the rotating shaft mechanism, thereby causing the sliding body at the first end of the connecting swing arm to move in the direction opposite to the second direction within the sliding groove of the first cover plate. Because the sliding body of the connecting swing arm moves in the direction opposite to the second direction within the sliding groove of the first cover plate, the shaft seat can be driven by the sliding action of the connecting swing arm to move in the first direction relative to the first cover plate, thereby driving the second cover plate, which is fixedly connected to the shaft seat, to move in the first direction relative to the first cover plate. The reverse is also true.

[0029] In a possible implementation manner, the second mounting hole communicates with the first mounting hole and the interior of the chassis, and the second connecting portion passes through the second mounting hole.

[0030] Under this setting, the connection relationship between the rotating shaft mechanism and the connecting swing arm can be utilized to transmit the rotational motion of the rotating shaft mechanism to the connecting swing arm, and the rotational motion can be converted into sliding motion in the slide groove through the sliding body on the connecting swing arm, so as to utilize the sliding action of the connecting swing arm to complete the forward and backward movement of the second cover plate relative to the first cover plate, so as to achieve the purpose of opening and closing the second cover plate relative to the first cover plate and the box body.

[0031] In one possible embodiment, the electronic device further includes a second axis, which is passed through the handle and the rotating shaft mechanism, and the center line of the second axis is parallel to the first direction. The handle can rotate around the center line of the second axis to engage with or disengage from the second cover.

[0032] With this arrangement, when the second cover is closed relative to the first cover and the box body, the second shaft can be rotated to retract the handle into the first receiving cavity of the second cover, locking the handle to the second cover. Alternatively, when the second cover is to be unlocked relative to the first cover and the box body, the second shaft can be rotated to disengage the handle from the second cover, gradually releasing the handle from the first receiving cavity of the second cover, thereby completing the locking and unlocking of the second cover relative to the first cover and the box body.

[0033] In a possible embodiment, the first boss is provided with a latch hole, the latch hole communicating with the first receiving cavity and the interior of the chassis, and the latch hole and the first mounting hole are arranged opposite to each other in the second direction;

[0034] The handle includes a handle body, a handle holding portion, and a third shaft. One end of the handle body is connected to the rotating shaft mechanism, and the other end of the handle body is connected to the handle holding portion via the third shaft. The center line of the third shaft is parallel to the second direction.

[0035] The handle holding portion can rotate around the center line of the third shaft, so that the handle holding portion passes through the holding hole and is held by the second cover plate, and the second cover plate is fixedly connected to the box body; or

[0036] The handle holding portion can rotate around the center line of the third shaft to disengage the handle holding portion from the clamping hole and disengage the second cover plate from the box body.

[0037] In one possible embodiment, the handle holding portion includes a accommodating portion, the accommodating portion is located in the handle body, the third axis passes through the accommodating portion and the handle body, the accommodating portion is provided with a cavity, and the handle also includes a second elastic member, the second elastic member is wound around the third axis, one end of the second elastic member abuts against the handle body, and the other end of the second elastic member abuts against the bottom wall of the cavity.

[0038] On the one hand, the provision of a second elastic member can limit the rotation angle of the handle clamping portion, preventing excessive rotation of the handle clamping portion, which could reduce the reliability of the lock assembly. On the other hand, the provision of the second elastic member can allow the handle clamping portion to twist multiple times due to its elastic return action, thus improving reliability. For example, the second elastic member can be a torsion spring.

[0039] In a possible implementation, when the second cover is fixedly connected to the box body, one end of the support member is connected to the first cover, and the other end of the support member extends into the interior of the chassis and is located below the second cover.

[0040] Under this setting, the support member can have sufficient connection strength, can better provide strong support for other components in the locking assembly, and has good reliability.

[0041] In a possible implementation, the electronic device is a server. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0077] And / or: It is just a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0078] Multiple: refers to two or more than two.

[0079] 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.

[0080] The specific implementation of the present application will be clearly described below with reference to the accompanying drawings.

[0081] An embodiment of the present application provides an electronic device.

[0082] 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.

[0083] Please refer to Figure 1 , Figure 1 It is a structural diagram of the electronic device 200 provided in an embodiment of the present application.

[0084] 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 width direction of the electronic device 200 is the second direction Y, and the height direction of the electronic device 200 is the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0085] 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 devices in the chassis 210 need to be maintained frequently. Therefore, in the design of the electronic device 200, the second cover plate (not shown) of the chassis 210, as a component that is frequently disassembled during operation and maintenance, needs to be designed as a quickly removable component, and the overall plug-in and pull-out force during the disassembly of the second cover plate of the chassis 210 is large, requiring a certain amount of power assistance. Therefore, the tool-free disassembly locking assembly 100 becomes a component that helps the chassis 210 to be disassembled and maintained. Specifically, the chassis 210 has an open state and a closed state. The locking assembly 100 enables the chassis 210 to switch between an open state and a closed state, and to maintain it in an open state or a closed state. When the chassis 210 is in a closed state, the upper cover and the case body of the chassis 210 can be fixedly connected. 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.

[0086] It should be noted that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 200. In other embodiments of the present application, the electronic device 200 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0087] Please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 The exploded schematic diagram of the electronic device 200 is shown. Figure 3 yes Figure 1 The following is a schematic diagram of the structure of the chassis 210 of the electronic device 200. The chassis 210 may include a housing 220, a first cover 230, and a second cover 240. The first cover 230 and the second cover 240 are both connected to one side of the housing 220 and arranged along a first direction X (i.e., the longitudinal direction of the housing 220). The second cover 240 is the upper cover mentioned above that needs to be frequently and quickly removed.

[0088] The housing 220 may include a bottom plate 2210, a first side plate 2220, and a second side plate 2230. The bottom plate 2210 may serve as a supporting plate for the chassis 210 and various components within the electronic device 200 may be arranged thereon. The bottom plate 2210, the first side plate 2220, and the second side plate 2230 cooperate to enclose a receiving space W of the housing 220. The receiving space W may accommodate various components of the electronic device 200, such as a fan module, a power supply module, a hard disk module, and a circuit board. It is understandable that the various components listed above may be components in the chassis 210 described above that require frequent maintenance. Specifically, the fan module may dissipate heat generated during the operation of the electronic device 200, the power supply module may provide a stable and reliable voltage and current input for the server of the electronic device 200, the hard disk module may realize the data storage function of the electronic device 200, and the circuit board may provide a connection platform for various components in the electronic device 200, which may constitute the circuit system of the electronic device 200.

[0089] Specifically, the bottom plate 2210 may include a third end 2211 and a fourth end 2212, which are arranged opposite each other along a first direction X (i.e., the length direction of the bottom plate 2210). A first side plate 2220 and a second side plate 2230 are respectively disposed on either side of the bottom plate 2210, and both the first side plate 2220 and the second side plate 2230 extend along the first direction X and are arranged opposite each other in a second direction Y (i.e., the width direction of the bottom plate 2210).

[0090] In one possible embodiment, a plurality of first card slots 2240 are provided on the first side panel 2220 and / or the second side panel 2230, and the plurality of first card slots 2240 are spaced apart on the first side panel 2220 and / or the second side panel 2230. Here, "and / or" may mean that only the first side panel 2220 is provided with a plurality of first card slots 2240, or only the second side panel 2230 is provided with a plurality of first card slots 2240, or both the first side panel 2220 and the second side panel 2230 are provided with a plurality of first card slots 2240. The following description will be based on an example in which both the first side panel 2220 and the second side panel 2230 are provided with a plurality of first card slots 2240, but it should be understood that the present invention is not limited thereto.

[0091] Each first latching slot 2240 includes two slot walls arranged opposite each other along the first direction X. One slot wall is provided with a first latching body 2241. The first latching body 2241 can latch with a second latching slot 2432 of the second cover plate 240, described later, to ensure stable and reliable alignment between the second cover plate 240 and the case 220. Furthermore, a gap is provided between the first latching body 2241 and the other slot wall. This gap allows the second cover plate 240 to slide a certain distance on the case 220 along the first direction X. It will be appreciated that the provision of this gap provides sufficient space for the second cover plate 240 to slide on the case 220, thereby facilitating locking and unlocking of the second cover plate 240 with the case 220. Specifically, when the second cover plate 240 slides on the box body 220 in a direction toward the first cover plate 230 (i.e., the opposite direction of the first direction X) and slides until the first retaining body 2241 of the box body 220 and the second retaining groove 2432 of the second cover plate 240 engage with each other, a stable abutting relationship is established between the second cover plate 240 and the box body 220, which facilitates the relative fixation between the second cover plate 240 and the box body 220. When the second cover plate 240 slides on the box body 220 in a direction away from the first cover plate 230 (i.e., the first direction X) and slides until the first retaining body 2241 of the box body 220 and the second retaining groove 2432 of the second cover plate 240 gradually disengage, the second cover plate 240 can be detached from the box body 220, which facilitates the removal of the second cover plate 240.

[0092] In one possible implementation, Figure 3 As shown, the chassis 210 may further include a plurality of partitions 2250, each of which is disposed within the housing 220. Specifically, the plurality of partitions 2250 are disposed at the third end 2211 of the bottom plate 2210. The plurality of partitions 2250 extend along the first direction X and are spaced apart along the second direction Y. The gap between two adjacent partitions 2250 can be used to accommodate a hard disk module.

[0093] Please refer to Figure 4 and Figure 5 , Figure 4 yes Figure 1 The schematic diagram of the assembly of the first cover 230 and the box 220 of the electronic device 200 is shown in FIG. Figure 5 yes Figure 1 FIG. 1 is a schematic structural diagram of a first cover plate 230 of an electronic device 200 .

[0094] The first cover plate 230 covers the case 220 and the plurality of partitions 2250. The first cover plate 230 and the bottom plate 2210 of the case 220 are arranged relative to each other in the third direction Z. The first cover plate 230, the case 220 and the plurality of partitions 2250 can cooperate to form a partial structure of a hard disk cage, and the hard disk cage can be used to set a hard disk module. Among them, the first cover plate 230 can be used as the cover plate of the chassis 210 and cooperate with the case 220 and the second cover plate 240 to form the appearance structure of the chassis 210. The first cover plate 230 can also be used as the cover plate of the hard disk cage and cooperate with the case 220 to form the appearance structure of the hard disk cage. It should be noted that the hard disk cage is not limited to Figure 4 The partial structure shown may also include a hard disk backplane, etc. The embodiments of the present application do not impose strict restrictions on the actual structure of the hard disk cage.

[0095] In the embodiment of the present application, the first cover plate 230 may include a first cover plate body 2310 , a first limiting portion 2320 and a first fixing portion 2330 .

[0096] The first cover body 2310 includes two first edges 2311 oppositely disposed along a first direction X and two second edges 2312 oppositely disposed along a second direction Y. The two second edges 2312 are connected between the two first edges 2311 .

[0097] The first limiting portion 2320 is provided at one of the two first edges 2311, which is close to the second cover plate 240. One end of the first limiting portion 2320 is connected to the first edge 2311, and the other end of the first limiting portion 2320 extends in a direction away from the first edge 2311. The first limiting portion 2320 is used to cooperate with the second limiting portion 2420 of the second cover plate 240 described below to achieve relative fixation between the first cover plate 230 and the second cover plate 240. The first limiting portion 2320 is provided with a first notch 2321, for example, as shown in FIG. Figure 5 , the first notch 2321 can be located in the middle of the first limiting portion 2320. The first notch 2321 divides the first limiting portion 2320 into a first sub-portion 2322 and a second sub-portion 2323, thereby providing a space for accommodating part of the lock assembly 100 by utilizing the gap between the first sub-portion 2322 and the second sub-portion 2323. It should be noted that the first notch 2321 is not limited to being located in the middle of the first limiting portion 2320. It can also be located at any position on the first limiting portion 2320 that conveniently provides a certain amount of space. The embodiments of the present application do not impose strict restrictions on this.

[0098] In one possible implementation, Figure 5 As shown, the length of the other end of the first limiting portion 2320 in the third direction Z may be greater than the length of one end of the first limiting portion 2320 in the third direction Z.

[0099] There are two first fixing portions 2330, each of which is located on the two second edges 2312. Each first fixing portion 2330 protrudes relative to one of the second edges 2312 and extends toward the box body 220. With this arrangement, when the first cover 230 is closed on the box body 220, the two first fixing portions 2330 are located on the outside of the box body 220, and the two first fixing portions 2330 can respectively support the box body 220 from both sides of the box body 220. In this case, the two first fixing portions 2330 can be locked to the box body 220 using fixing members such as screws, bolts, etc., thereby achieving a fixed connection between the first cover 230 and the box body 220. This helps minimize the possibility of problems such as the first cover 230 shaking or the first cover 230 slipping off the box body 220, thereby improving reliability.

[0100] Please refer to Figure 6 、 Figure 7 and Figure 8 , Figure 6 yes Figure 1 The assembly diagram of the box 220 of the electronic device 200 is shown in FIG. Figure 7 yes Figure 1 The second cover plate 240 of the electronic device 200 is a schematic structural diagram at an angle. Figure 8 yes Figure 1 The structure diagram of the second cover plate 240 of the electronic device 200 is shown in another angle.

[0101] The second cover 240 covers the case 220 and is disposed opposite the bottom plate 2210 of the case 220 in the third direction Z. The second cover 240 can cooperate with the first cover 230 to close the top of the case 220 and, together with the case 220 and the first cover 230, form the exterior structure of the chassis 210. The second cover 240 may include a second cover body 2410, a second stopper 2420, and a second fixing portion 2430.

[0102] The second cover body 2410 includes two third edges 2411 disposed opposite each other along the first direction X and two fourth edges 2412 disposed opposite each other along the second direction Y. The two fourth edges 2412 are connected between the two third edges 2411. The second cover body 2410 also includes a first surface 2413 and a second surface 2414 disposed opposite each other along the third direction Z. The first surface 2413 is the surface of the second cover body 2410 facing the box body 220, and the second surface 2414 is the surface of the second cover body 2410 facing away from the box body 220.

[0103] The second cover body 2410 is provided with a first boss 2440, which protrudes toward the base plate 2210. For example, the first boss 2440 can be in the shape of a cotton swab. A first receiving cavity 2441 is provided within the first boss 2440. The first receiving cavity 2441 has a first opening 2442. The first opening 2442 of the first receiving cavity 2441 is located on the second surface 2414, and the first opening 2442 can connect the first receiving cavity 2441 with the exterior of the chassis 210. When visually observing the second surface 2414 of the second cover 240, it can be observed that the first receiving cavity 2441 is recessed relative to the second surface 2414 of the second cover 240. The first receiving cavity 2441 can accommodate a portion of the structure of the latch assembly 100. For example, a portion of the structure of the latch assembly 100 can be accommodated in the first receiving cavity 2441 and exposed to the exterior of the chassis 210 through the first opening 2442 of the first receiving cavity 2441. Therefore, when the human eye visually observes the second cover 240 , the locking assembly 100 installed on the first cover 230 and the second cover 240 can be observed through the first opening 2442 of the first receiving cavity 2441 , and the movement state of the locking assembly 100 relative to the chassis 210 can be observed.

[0104] The first boss 2440 further defines a first mounting hole 2443 and a latching hole 2444. The latching hole 2444 and the first mounting hole 2443 are arranged opposite each other in the second direction Y. The first mounting hole 2443 connects the first receiving cavity 2441 with the interior of the chassis 210 (i.e., the receiving space W of the case 220). The first mounting hole 2443 allows the hinge mechanism 20, described below, to pass through. The latching hole 2444 connects the first receiving cavity 2441 with the interior of the chassis 210 (i.e., the receiving space W of the case 220). The latching hole 2444 allows the handle 50, described below, to be latched.

[0105] In the embodiment of the present application, the second limiting portion 2420 is provided on one of the two third edges 2411 that is closer to the first cover plate 230. The second limiting portion 2420 is used to cooperate with the first limiting portion 2320 of the first cover plate 230 to achieve relative fixation between the first cover plate 230 and the second cover plate 240. One of the first limiting portion 2320 and the second limiting portion 2420 may be a plug-in body, and the other may be a slot. The mutual positioning of the first cover plate 230 and the second cover plate 240 is achieved by the corresponding insertion of the plug-in body and the slot.

[0106] In one possible implementation, Figure 7 and Figure 8As shown, the second limiting portion 2420 may include a first section 2421, a second section 2422 and a third section 2423, the first section 2421 is connected to the first surface 2413 of the first cover body 2310, the second section 2422 and the first section 2421 are spaced and arranged parallel to each other in the third direction Z, and the third section 2423 is bent and connected between the first section 2421 and the second section 2422. By connecting the first section 2421, the third section 2423 and the second section 2422 in sequence, the first section 2421, the second section 2422 and the third section 2423 can cooperate to form a slot, and the slot can be used for the plug-in body formed by the first limiting portion 2320 of the first cover plate 230 to limit the relative position between the second cover plate 240 and the first cover plate 230, providing a sense of resistance after the second limiting portion 2420 and the first limiting portion 2320 are plugged into place, preventing the second cover plate 240 from continuing to move toward the first cover plate 230 and squeezing the first cover plate 230, thereby having good reliability.

[0107] In this embodiment, the second limiting portion 2420 may further include a fourth section 2424, one end of which is connected to the end of the second section 2422 away from the third section 2423, and the other end of the fourth section 2424 is bent and extended in a direction away from the first section 2421. Thus, the fourth section 2424, which is bent away from the first section 2421, can have a wider distance from the first section 2421 than the second section 2422, so that the fourth section 2424 and the first section 2421 cooperate to form a trumpet-shaped expansion, thereby providing a guide for the insertion of the first limiting portion 2320 of the first cover plate 230 into the second limiting portion 2420 of the second cover plate 240. The wider spacing can also provide a certain amount of tolerance space for the first limiting portion 2320 of the first cover plate 230. 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 slide into the second limiting portion 2420 of the second cover plate 240 under the guidance of the fourth section 2424, thereby further improving the plug-in efficiency and plug-in 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.

[0108] Please continue reading Figure 7 and Figure 8In the embodiment of the present application, the second limiting portion 2420 is provided with a second notch 2425, and the second notch 2425 is in communication with the receiving space W of the box body 220. For example, the second notch 2425 can separate the second limiting portion 2420 into a third sub-portion 2426 and a fifth sub-portion 2428. The gap area between the third sub-portion 2426 and the fourth sub-portion 2427 can provide space for accommodating part of the locking assembly 100. In addition, the fourth sub-portion 2427 can be further provided in the second notch 2425, thereby enhancing the reliability of the connection between the second limiting portion 2420 and the first limiting portion 2320. For example, the second notch 2425 can be used to accommodate part of the structure of the locking assembly 100. The third sub-portion 2426 of the second position-limiting portion 2420 can be disposed correspondingly to the first sub-portion 2322 of the first position-limiting portion 2320, and the fifth sub-portion 2428 of the second position-limiting portion 2420 can be disposed correspondingly to the second sub-portion 2323 of the first position-limiting portion 2320. It should be noted that the second notch 2425 is not limited to the aforementioned position and can be disposed at any position on the second position-limiting portion 2420 that conveniently provides a certain amount of space, and the embodiments of the present application are not strictly limited to this.

[0109] There are two second fixing portions 2430, one located on each of the four fourth edges 2412. Each second fixing portion 2430 protrudes from one of the four fourth edges 2412 and extends toward the box body 220. With this arrangement, when the second cover 240 is closed over the box body 220, both second fixing portions 2430 are located outside the box body 220. The two first fixing portions 2330 can respectively support the box body 220 from both sides, ensuring stable and reliable contact between the second cover 240 and the box body 220.

[0110] The inner surface of at least one second fixing portion 2430 is provided with a plurality of second retaining bodies 2431, which are spaced apart on the second fixing portion 2430. Each second retaining body 2431 has a gap with the second fixing portion 2430 in the second direction Y, so that a second retaining body 2431 can cooperate with the second fixing portion 2430 to form a second retaining slot 2432. The second retaining slot 2432 can retain the first retaining body 2241 of the first cover plate 230 described above to ensure the alignment stability and reliability between the second cover plate 240 and the housing 220. The entrance of the second retaining slot 2432 is open, so that the entrance of the second retaining slot 2432 can serve as an insertion interface for the first retaining body 2241 and the second retaining slot 2432 to guide the insertion of the first retaining body 2241 and the second retaining slot 2432. The outlet of the second card slot 2432 is closed, so that when the first card holder 2241 and the second card slot 2432 are plugged into place, a stable abutment relationship is formed between the first card holder 2241 and the second card slot 2432, which is conducive to the relative fixation between the first cover plate 230 and the second cover plate 240.

[0111] In one possible embodiment, the electronic device 200 may further include a fan module (not shown), which is installed inside the chassis 210 and can dissipate heat for the electronic device 200. For example, the fan module can dissipate heat for heat-generating components within the electronic device 200, such as a hard disk module, circuit board, memory, processor, etc., that generate heat during operation, thereby ensuring that the electronic device 200 has good thermal uniformity and cooling performance, thereby improving the operating stability and reliability of the electronic device 200.

[0112] Specifically, there can be multiple fan modules, each of which is arranged on the bottom plate 2210 along the second direction Y. The multiple fan modules are spaced apart from the multiple partitions 2250 and the first cover plate 230 along the first direction X. For example, the number of fan modules can be five. It should be noted that the embodiments of the present application do not impose specific restrictions on the number or type of fan modules, as long as they can meet the heat dissipation performance of the electronic device 200.

[0113] It can be understood that cold air enters the interior of the electronic device 200 through the external environment, and turns into hot air by carrying the heat generated by the hard disk module at the end of the chassis 210 where the hard disk module is provided. The hot air continues to flow and gradually flows from the third end 2211 of the bottom plate 2210 to the fourth end 2212 of the bottom plate 2210. Since multiple heat dissipation devices such as fan modules are provided in the aforementioned flow path, the hot air can be discharged from the electronic device 200 after passing through these heat dissipation devices. The cold and hot air circulate alternately and repeatedly to complete the uninterrupted heat exchange of the electronic device 200, ensuring that the electronic device 200 always has good heat dissipation performance.

[0114] In an embodiment of the present application, the latch assembly 100 is connected to the first cover plate 230 and the second cover plate 240. The latch assembly 100 can achieve relative fixation between the second cover plate 240, the box body 220, and the first cover plate 230, thereby placing the chassis 210 in a closed state. The latch assembly 100 can also disengage the second cover plate 240 from the box body 220 and the first cover plate 230, thereby placing the chassis 210 in an open state. The latch assembly 100 may include a support member 10, a rotating shaft mechanism (20a, 20b), a second shaft (30a, 30b), a connecting swing arm (40a, 40b), and a handle (50a, 50b). The structural possibilities of the latch assembly will be described below through two embodiments.

[0115] First embodiment:

[0116] Please refer to Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of a state in which the locking assembly 100 provided in the first embodiment of the present application is installed in the chassis 210. Figure 10 yes Figure 9 The exploded view of the partial structure of the locking assembly 100 of the electronic device 200 is shown. Figure 9 The second cover plate 240 is not shown. Figure 10 The support member 10 is not shown.

[0117] See also Figure 11 , Figure 11 yes Figure 9 The figure shows an assembly diagram of the support member 10 of the locking assembly 100 and the first cover plate 230 of the electronic device 200.

[0118] The support member 10 is connected to the first cover plate 230. When the second cover plate 240 is fixedly connected to the housing 220, one end of the support member 10 is connected to the first cover plate 230, and the other end of the support member 10 extends into the interior of the chassis 210, and the other end of the support member 10 is located below the second cover plate 240. A portion of the support member 10 can also be located in the first notch 2321 of the first cover plate 230, with the two sides of the support member 10 respectively connected to the first sub-portion 2322 and the second sub-portion 2323 of the first cover plate 230. This arrangement not only fully utilizes the space provided by the first notch 2321 to accommodate the support member 10 therein, thereby improving space utilization within the chassis 210. Furthermore, because the support member 10 is connected to both the first sub-portion 2322 and the second sub-portion 2323 of the first limiting portion 2320, the support member 10 has sufficient connection strength, providing better support for other components of the locking assembly 100 and improving reliability.

[0119] The support member 10 is provided with a slide groove 11 extending along the second direction Y. The slide groove 11 can also penetrate the support member 10 along the third direction Z, thereby forming a through-slot structure. The slide groove 11 allows the connecting swing arm 40a to move therein. The slide groove 11 includes a first side wall 111 and a second side wall 112. The second side wall 112 is arranged opposite the first side wall 111 in the second direction Y, and the second side wall 112 is closer to the rotating shaft mechanism 20a than the first side wall 111.

[0120] Please refer to Figure 12 and Figure 13 , Figure 12 yes Figure 9 The locking assembly 100 is shown as a schematic diagram of a state in which the locking assembly 100 is installed in the chassis 210. Figure 13 yes Figure 9 The locking assembly 100 is shown in another state diagram of the chassis 210. Figure 12 and Figure 13 The second cover plate 240 is not shown in the figures.

[0121] like Figure 12 As shown, the first side wall 111 can contact the connecting swing arm 40a. In this arrangement, because the first side wall 111 has good supporting strength, the first side wall 111 can provide stable contact reliability for the connecting swing arm 40a. When the connecting swing arm 40a moves within the slide slot 11 until it contacts the first side wall 111, the first side wall 111 can serve as the first support point of the support member 10 and provide strong support for the connecting swing arm 40a. The action and reaction force exerted by the mutual abutment between the first side wall 111 and the connecting swing arm 40a can maintain the closed state of the chassis 210.

[0122] like Figure 13 As shown, the second side wall 112 can contact the connecting swing arm 40a. In this arrangement, due to the excellent support strength of the second side wall 112, the second side wall 112 can provide stable contact reliability for the connecting swing arm 40a. When the connecting swing arm 40a moves within the slide slot 11 until it contacts the second side wall 112, the second side wall 112 can serve as a second support point for the support member 10, providing strong support for the connecting swing arm 40a. The action and reaction force exerted by the mutual abutment between the second side wall 112 and the connecting swing arm 40a can switch the chassis 210 from the closed state to the open state.

[0123] Please refer again Figure 11It is understood that the first cover plate 230, the housing 220, and the plurality of partitions 2250 described above can cooperate to form a partial structure of a hard drive cage for accommodating a hard drive module. When the plurality of partitions 2250, the housing 220, and the first cover plate 230 are assembled in place, a hard drive backplane (not shown) can be assembled on the plurality of partitions 2250 in the opposite direction of the first direction X. Furthermore, because the majority of the support member 10 is located in the first notch 2321 of the first limiting portion 2320, the support member 10 does not block the gap between the first cover plate 230 and the fan module. The hard drive backplane (not shown) can be conveniently and quickly installed in the opposite direction of the first direction X to the side of the first cover plate 230 and the plurality of partitions 2250 near the fan module, ensuring that the assembly of the hard drive backplane is not blocked by the support member 10. This simplifies the assembly process and helps improve the assembly efficiency of the electronic device 200.

[0124] Since cold air from the external environment enters from the front end of the chassis 210 (i.e., the side of the chassis 210 where the first cover plate 230 is provided), the cold air picks up the heat from the heat-generating components inside the chassis 210 and becomes hot air, which is then discharged from the rear end of the chassis 210 (i.e., the side of the chassis 210 where the second cover plate 240 is located away from the first cover plate 230). The support member 10 is located in the gap between the fan module and the first cover plate 230, so the support member 10 is actually located at the front end of the fan module. Furthermore, because the distance between the support member 10 and the second cover plate 240 of the chassis 210 is smaller than the distance between the support member 10 and the bottom plate 2210 of the chassis 210, the support member 10 is closer to the second cover plate 240 of the chassis 210 than to the bottom plate 2210 of the chassis 210. That is, the support member 10 is disposed on the top side of the chassis 210.

[0125] On the one hand, compared to the prior art method of placing part of the upper cover lock structure on the bottom plate of the chassis, the fan module needs to avoid the upper cover lock because the upper cover lock significantly blocks the air inlet channel. In the embodiment of the present application, the support member 10 is placed on the top side of the chassis 210. This can free up the space in the electronic device 200 that is occupied by avoiding the upper cover lock, and this part of the space can be vacated to provide more fan modules. Therefore, the number of fan modules can be increased while ensuring that the electronic device 200 has good working performance, thereby further improving the heat dissipation performance of the electronic device 200. On the other hand, placing the support member 10 on the top side of the chassis 210 can make the air inlet channel of the fan module transparent, which can minimize the space occupied by the fan module and the adverse effects on the selection of the fan module caused by the upper cover lock. It can also minimize the possibility of the problem of increased wind resistance of the entire system and difficulty in improving the heat dissipation specifications of the entire system due to the locking assembly 100 blocking the air inlet of the fan module, which is conducive to improving the heat dissipation capacity of the entire machine.

[0126] Please refer to Figure 12 、 Figure 13 、 Figure 14 and Figure 15 , Figure 14 yes Figure 12 The structural diagram of the connecting swing arm 40a of the lock assembly 100 is shown at an angle. Figure 15 yes Figure 12 The structure diagram of the connecting swing arm 40a of the locking assembly 100 is shown at another angle.

[0127] The connecting swing arm 40a is located inside the chassis 210. One end of the connecting swing arm 40a is connected to the rotating shaft mechanism 20a, and the other end of the connecting swing arm 40a is mounted on the slide groove 11. Specifically, the connecting swing arm 40a may include a swing arm body 41a and a sliding body 42a. The swing arm body 41a includes a first connecting surface 411a and a second connecting surface 412a that are oppositely arranged. The first connecting surface 411a of the swing arm body 41a is the surface of the swing arm body 41a facing the second cover plate 240, and the second connecting surface 412a of the swing arm body 41a is the surface of the swing arm body 41a facing away from the second cover plate 240. The swing arm body 41a also includes a first end 413a and a second end 414a. The surface of the first end 413a of the swing arm body 41a and the surface of the second end 414a of the swing arm body 41a together constitute partial surfaces of the aforementioned first connecting surface 411a and second connecting surface 412a. The first end 413a of the swing arm body 41a is the end of the swing arm body 41a installed in the slide groove 11, and the second end 414a of the swing arm body 41a is the end of the swing arm body 41a connected to the rotating shaft mechanism 20a.

[0128] Please continue reading Figure 12 、 Figure 14 and Figure 15The first end 413a of the swing arm body 41a is connected to the sliding body 42a. Specifically, one end of the sliding body 42a is connected to the first end 413a of the swing arm body 41a, and the other end of the sliding body 42a extends away from the swing arm body 41a. The sliding body 42a is arranged to protrude relative to the second connecting surface 412a of the swing arm body 41a. The sliding body 42a is disposed in the chute 11. When the swing arm body 41a is rotated by the rotating shaft mechanism 20a, the sliding body 42a can be driven to reciprocate within the chute 11 along the second direction Y and in a direction opposite to the second direction Y, thereby moving the swing arm body 41a relative to the first cover plate 230. Specifically, when the second cover plate 240 is fixedly connected to the chassis 210, the handle 50a is engaged with the second cover plate 240, and the sliding body 42a can move within the chute 11 until it abuts against the first side wall 111, thereby fixing the second cover plate 240 to the chassis 210. When the second cover 240 is disengaged from the chassis 210, the handle 50a is disengaged from the second cover 240, and the sliding body 42a can move within the chute 11 until it abuts against the second side wall 112, thereby disengaging the second cover 240 from the chassis 210. Alternatively, the sliding body 42a can move within the chute 11 until it is located between the first side wall 111 and the second side wall 112, thereby unlocking the second cover 240 from the chassis 210, thereby disengaging the second cover 240 from the chassis 210. It should be noted that the second cover 240 and the chassis 210 can also be in an unlocked state when the sliding body 42a is at any position between the first side wall 111 and the second side wall 112 in the chute 11, and this is not strictly limited in this embodiment.

[0129] The second end 414a of the swing arm body 41a is provided with a second boss 415a, which is arranged to protrude relative to the second connecting surface 412a. For example, the second boss 415a can be rectangular. A second receiving cavity 416a is provided within the second boss 415a, and the second receiving cavity 416a has a second opening 417a. The second opening 417a of the second receiving cavity 416a is located on the first connecting surface 411a, and the second opening 417a can connect the second receiving cavity 416a with the interior of the chassis 210. When the human eye visually observes the first connecting surface 411a of the swing arm body 41a, it can be observed that the second receiving cavity 416a is recessed relative to the first connecting surface 411a of the swing arm body 41a. The first receiving cavity 2441 can accommodate part of the structure of the rotating shaft mechanism 20a.

[0130] The second boss 415a also defines a second mounting hole 418a, which connects the second receiving cavity 416a with the interior of the chassis 210. Specifically, the second mounting hole 418a is a through hole through which the hinge mechanism 20a can be inserted. When the connecting swing arm 40a is mounted to the chassis 210, the second receiving cavity 416a of the connecting swing arm 40a can communicate with the first receiving cavity 2441 of the second cover plate 240 via the first mounting hole 2443 of the first receiving cavity 2441. The second mounting hole 418a of the second receiving cavity 416a corresponds to the first mounting hole 2443 of the first receiving cavity 2441, thereby enabling the hinge mechanism 20a to be inserted between the second cover plate 240 and the connecting swing arm 40a.

[0131] Please refer to Figure 16 and Figure 17 , Figure 16 yes Figure 9 The locking assembly 100 is mounted on the second cover plate 240. Figure 17 yes Figure 10 The diagram shows a structure in which the rotating shaft mechanism 20a is mounted on the second cover plate 240. In the third direction Z, the distance between the first end 413a of the swing arm body 41a and the second cover plate 240 is smaller than the distance between the second end 414a of the swing arm body 41a and the second cover plate 240. In other words, the first end 413a of the swing arm body 41a and the second end 414a of the swing arm body 41a are disposed opposite each other in the third direction Z. The difference in distance between the first end 413a of the swing arm body 41a and the second end 414a of the swing arm body 41a in the third direction Z can be adapted to the protruding height of the first boss 2440 relative to the second cover plate body 2410. Under this setting, the support member 10 and the first end 413a of the swing arm body 41a can be arranged relative to each other in the third direction Z, and the second end 414a of the swing arm body 41a and the first boss 2440 of the second cover body 2410 can be arranged relative to each other in the third direction Z, so that the position of connecting the swing arm 40a can be reasonably arranged in the confined space inside the chassis 210, making the layout of the various components of the locking assembly 100 compact.

[0132] The hinge mechanism 20a is disposed through the second cover plate 240. Specifically, one end of the hinge mechanism 20a is located within the first receiving cavity 2441 of the first boss 2440, and the hinge mechanism 20a extends through the first mounting hole 2443 of the first receiving cavity 2441. When the second cover plate 240 is fixedly connected to the housing 220, the other end of the hinge mechanism 20a is located within the chassis 210. The centerline C1 of the hinge mechanism 20a is parallel to the third direction Z, and the hinge mechanism 20a is capable of rotating about the centerline C1.

[0133] Please refer to Figure 10 and Figure 18, Figure 18 yes Figure 10 The exploded schematic diagram of the rotating shaft mechanism 20a is shown. The rotating shaft mechanism 20a may include a shaft seat 21a, a first shaft body 22a and a first elastic member 23a.

[0134] Please refer to Figure 17 、 Figure 18 and Figure 19 , Figure 19 yes Figure 18 The shaft seat 21a is shown as a schematic structural diagram at an angle. The shaft seat 21a is installed in the first mounting hole 2443 of the first receiving cavity 2441. Specifically, the shaft seat 21a may include a carrier 211a, a first connecting portion 212a, and a second connecting portion 213a. The first connecting portion 212a is connected to one side of the carrier 211a, and the first connecting portion 212a is located in the first receiving cavity 2441. The first connecting portion 212a is provided with a first through hole 214a, which passes through the first connecting portion 212a along the first direction X, and the first through hole 214a is used for allowing the second shaft body 30a to pass therethrough. The carrier 211a is located in the first receiving cavity 2441 and covers the first mounting hole 2443. With this arrangement, when the shaft seat 21a is installed in the first mounting hole 2443 of the first receiving cavity 2441, the carrier 211a can act as a stop, thereby stopping the first connecting portion 212a of the shaft seat 21a in the first receiving cavity 2441, preventing the first connecting portion 212a of the shaft seat 21a from passing through the first mounting hole 2443 and extending into the interior of the chassis 210. The second connecting portion 213a is connected to the other side of the carrier 211a and passes through the first mounting hole 2443 of the first receiving cavity 2441. When the second cover 240 is fixedly connected to the housing 220, the second connecting portion 213a extends into the interior of the chassis 210. Specifically, the second connecting portion 213a is located within the first mounting hole 2443 of the first receiving cavity 2441 and within the second receiving cavity 416a. With this arrangement, the second cover plate 240 and the connecting arm 40a cooperate to accommodate and secure the shaft seat 21a, ensuring a stable and reliable connection between the shaft seat 21a, the second cover plate 240, and the connecting arm 40a. The second connecting portion 213a also defines a first blind hole 215a. The first blind hole 215a is located at the bottom of the second connecting portion 213a and extends from a side of the second connecting portion 213a away from the carrier 211a toward the carrier 211a. The first blind hole 215a is configured to connect to the first shaft 22a.

[0135] Please refer to Figure 12 、 Figure 13 and Figure 20 , Figure 20 yes Figure 12The diagram of the connection between the shaft seat 21a and the connecting swing arm 40a is shown. The second connecting portion 213a is inserted into the first mounting hole 2443 of the first receiving cavity 2441, and the portion of the second connecting portion 213a extending out of the first mounting hole 2443 of the first receiving cavity 2441 is fixedly connected to the second end 414a of the connecting swing arm 40a. Under this arrangement, the shaft seat 21a and the connecting swing arm 40a can be fixedly connected, so that the shaft seat 21a can move in conjunction with the connecting swing arm 40a due to the connection relationship between the two. For example, as Figure 12 and Figure 13 As shown, when the shaft seat 21a rotates counterclockwise about the centerline C1 of the rotating shaft mechanism 20a, the second end 414a of the connecting swing arm 40a can be driven by the second connecting portion 213a to rotate counterclockwise about the centerline C1 of the rotating shaft mechanism 20a, thereby causing the sliding body 42a located at the first end 413a of the connecting swing arm 40a to move within the sliding groove 11 of the first cover plate 230 in a direction opposite to the second direction Y. Since the sliding body 42a of the connecting swing arm 40a moves within the sliding groove 11 of the first cover plate 230 in a direction opposite to the second direction Y, the shaft seat 21a can be driven by the sliding action of the connecting swing arm 40a to move relative to the first cover plate 230 in the first direction X, thereby driving the second cover plate 240 fixedly connected to the shaft seat 21a to move relative to the first cover plate 230 in the first direction X. The reverse is also true.

[0136] Under this setting, the connection relationship between the rotating shaft mechanism 20a and the connecting swing arm 40a can be utilized to transmit the rotational motion of the rotating shaft mechanism 20a to the connecting swing arm 40a, and the rotational motion is converted into sliding motion in the slide groove 11 through the sliding body 42a on the connecting swing arm 40a, so as to utilize the sliding action of the connecting swing arm 40a to complete the forward and backward movement of the second cover plate 240 relative to the first cover plate 230, so as to achieve the purpose of opening and closing the second cover plate 240 relative to the first cover plate 230 and the box body 220.

[0137] Please refer to Figure 18 、 Figure 20 and Figure 21 , Figure 21 It is along Figure 12The schematic cross-sectional view taken along section line AA is shown. The first shaft 22a extends through the second mounting hole 418a of the second boss 415a and into the first blind hole 215a of the shaft seat 21a, securing the first shaft 22a to the shaft seat 21a. A first elastic member 23a is wound around the first shaft 22a, one end of which can be secured to the second end 414a of the connecting swing arm 40a. When the second cover 240 is secured to the housing 220, the first shaft 22a and the first elastic member 23a are located within the housing 210. The provision of the first elastic member 23a can, on the one hand, limit the rotation angle of the hinge mechanism 20a, preventing excessive rotation of the hinge mechanism 20a and reducing the reliability of the latch assembly 100. On the other hand, the provision of the first elastic member 23a allows the hinge mechanism 20a to undergo multiple torsional movements due to its elastic reset action, improving reliability. Exemplarily, the first elastic member 23a may be a torsion spring.

[0138] Please refer to Figure 22 、 Figure 23 and Figure 24 , Figure 22 yes Figure 10 The handle 50a is mounted on the second cover plate 240. Figure 23 yes Figure 9 The structural diagram of the locking assembly 100 is shown at an angle. Figure 24 yes Figure 22 The handle 50a is shown as an exploded schematic diagram. The handle 50a is connected to the second cover plate 240 via the rotating shaft mechanism 20a, and at least a portion of the handle 50a is located outside the chassis 210. For example, at least a portion of the handle 50a is located within the first receiving cavity 2441. The handle 50a can rotate about the centerline C1 of the rotating shaft mechanism 20a, driving the first end 413a of the connecting swing arm 40a to slide in the slide groove 11 in the opposite direction of the second direction Y, so that the second cover plate 240 moves relative to the first cover plate 230 and the housing 220 in the first direction X, thereby being fixedly connected to or disconnected from the housing 220. The handle 50a may include a handle body 51a, a handle holding portion 52a, a third shaft 53a, and a second elastic member 54a.

[0139] The handle body 51a has a cavity 511a that communicates with the exterior of the chassis 210 and can accommodate a portion of the handle retaining portion 52a. The handle body 51a may also include a fifth end 512a and a sixth end 513a, with the sixth end 513a and the fifth end 512a being disposed opposite each other in the second direction Y. The fifth end 512a is provided with a second through-hole 514a, which extends through the fifth end 512a along the first direction X and is in communication with the cavity 511a. The second through-hole 514a is configured to allow the second shaft 30a to pass through. The sixth end 513a is provided with a third through-hole 515a, which extends through the sixth end 513a along the first direction X and is in communication with the cavity 511a. The third through-hole 515a is configured to allow the third shaft 53a to pass through.

[0140] The second shaft 30a passes through the first through-hole 214a of the shaft seat 21a and the second through-hole 514a of the handle body 51a. The second shaft 30a extends through the shaft seat 21a and the handle body 51a. In other words, the second shaft 30a extends through the handle 50a and the rotating shaft mechanism 20a. The centerline C2 of the second shaft 30a is parallel to the first direction X. The handle body 51a can rotate about the centerline C2 of the second shaft 30a, thereby moving the handle 50a away from the second cover plate 240 and disengaging it, or moving the handle 50a toward the second cover plate 240 and engaging it. With this arrangement, when the handle 50a is rotated, the rotational movement of the second shaft 30a can be utilized to retract the handle 50a into the first receiving cavity 2441 of the second cover plate 240, causing the handle 50a to be locked with the second cover plate 240, thereby closing the second cover plate 240 relative to the first cover plate 230 and the box body 220. Alternatively, when the handle 50a is rotated, the rotational movement of the second shaft 30a can be utilized to disengage the handle 50a from the second cover plate 240, gradually releasing the handle 50a from the first receiving cavity 2441 of the second cover plate 240, thereby unlocking the second cover plate 240 relative to the first cover plate 230 and the box body 220, thereby completing the locking and unlocking of the second cover plate 240 relative to the first cover plate 230 and the box body 220.

[0141] Please refer to Figure 16 、 Figure 23 and Figure 24 One end of the handle body 51a is rotatably connected to the rotating shaft mechanism 20a via the second shaft 30a, and the other end of the handle body 51a is rotatably connected to the handle clamping portion 52a via the third shaft 53a. The center line C3 of the third shaft 53a is parallel to the second direction Y. Figure 16As shown, the handle holding portion 52a can rotate about the center line C3 of the third shaft 53a, so that the handle holding portion 52a passes through the locking hole 2444 of the second cover plate 240 and is locked with the second cover plate 240, thereby fixing the second cover plate 240 to the box body 220. Alternatively, the handle holding portion 52a can rotate about the center line C3 of the third shaft 53a to disengage the handle holding portion 52a from the locking hole 2444, thereby unlocking the handle holding portion 52a from the second cover plate 240 and disengaging the second cover plate 240 from the box body 220.

[0142] like Figure 23 and Figure 24 As shown, the handle holding portion 52a may include a pressing portion 521a, an accommodating portion 522a and a holding portion 523a.

[0143] The accommodating portion 522a can extend into the cavity 511a of the handle body 51a, that is, the accommodating portion 522a is located within the handle body 51a. The accommodating portion 522a is provided with a cavity 524a and a fourth through hole 525a. The cavity 524a is capable of accommodating the second elastic member 54a. The fourth through hole 525a is connected to the cavity 524a and extends through the accommodating portion 522a along the first direction X. The fourth through hole 525a is configured to allow the third shaft 53a to pass through. When the accommodating portion 522a extends into the cavity 511a of the handle body 51a, the fourth through hole 525a of the accommodating portion 522a corresponds to the third through hole 515a of the handle body 51a. The third shaft 53a passes through the third through hole 515a and the fourth through hole 525a, thereby intersecting the accommodating portion 522a and the handle body 51a. Under this arrangement, the handle holding portion 52a can rotate relative to the handle body 51a around the center line C3 of the third shaft 53a, so that the handle holding portion 52a is clamped or disengaged from the second cover plate 240. The second elastic member 54a is wound around the third shaft 53a, with one end of the second elastic member 54a abutting against the handle body 51a, and the other end of the second elastic member 54a abutting against the bottom wall of the cavity 524a. On the one hand, the provision of the second elastic member 54a can limit the rotation angle of the handle holding portion 52a, preventing the handle holding portion 52a from rotating too much and causing the working reliability of the lock assembly 100 to be reduced. On the other hand, the provision of the second elastic member 54a can allow the handle holding portion 52a to perform multiple torsional movements due to the elastic reset effect of the second elastic member 54a, thereby improving reliability. For example, the second elastic member 54a can be a torsion spring.

[0144] The pressing portion 521a and the holding portion 523a are respectively connected to adjacent sides of the accommodating portion 522a. The pressing portion 521a can provide a force application point for the operator, and the holding portion 523a can pass through the locking hole 2444 of the second cover plate 240 to lock with or release from the second cover plate 240. Specifically, when it is necessary to close the second cover plate 240 and lock the second cover plate 240 with the first cover plate 230 and the box body 220, the pressing portion 521a is pressed, causing the pressing portion 521a to drive the holding portion 523a through the locking hole 2444 of the second cover plate 240 and extend into the interior of the box body 220, thereby locking the holding portion 523a with the locking hole 2444 of the second cover plate 240, thereby helping to secure the second cover plate 240 to the first cover plate 230 and the box body 220. When it is necessary to open the second cover 240 and unlock it from the first cover 230 and the box body 220, the pressing portion 521a is pushed upward to rotate the handle clamping portion 52a about the center line C3 of the third shaft 53a. When the clamping portion 523a moves within the locking hole 2444 of the second cover 240 until it is no longer in contact with the locking hole 2444 of the second cover 240, the pressing portion 521a is pulled upward to disengage the clamping portion 523a from the locking hole 2444 of the second cover 240, thereby moving the handle clamping portion 52a away from the second cover 240. The second cover 240 can then be removed by rotating the handle body 51a.

[0145] Second embodiment:

[0146] In this embodiment, the same contents as those in the first embodiment will not be repeated, and the differences from the first embodiment will be described in detail below. Furthermore, unless there is a conflict, these descriptions are applicable to the lock assembly 100 shown in the first embodiment. The support member 10 in the lock assembly 100 can refer to the relevant description of the first embodiment. The different structures of the rotating shaft mechanism 20b, the second shaft 30b, the connecting swing arm 40b, and the handle 50b will be described in detail below.

[0147] Please refer to Figure 25 、 Figure 26 and Figure 27 , Figure 25 This is a schematic diagram of a state in which the locking assembly 100 provided in the second embodiment of the present application is installed in the chassis 210. Figure 26 yes Figure 25 The exploded schematic diagram of the partial structure of the lock assembly 100 is shown. Figure 27 yes Figure 25 The structure diagram of the connecting swing arm 40b of the locking assembly 100 is shown at one angle.

[0148] The connecting swing arm 40b is located inside the chassis 210. One end of the connecting swing arm 40b is connected to the rotating shaft mechanism 20b, and the other end of the connecting swing arm 40b is installed in the slide groove 11. Specifically, the connecting swing arm 40b may include a swing arm body 41b and a sliding body 42b. The swing arm body 41b includes a first connecting surface 411b and a second connecting surface 412b that are arranged opposite to each other. The first connecting surface 411b of the swing arm body 41b is the surface of the swing arm body 41b facing the second cover plate 240, and the second connecting surface 412b of the swing arm body 41b is the surface of the swing arm body 41b facing away from the second cover plate 240. The swing arm body 41b also includes a first end 413b and a second end 414b. The surface of the first end 413b of the swing arm body 41b and the surface of the second end 414b of the swing arm body 41b together constitute part of the surface of the aforementioned first connecting surface 411b and second connecting surface 412b. The first end 413b of the swing arm body 41b is the end of the swing arm body 41b installed in the slide groove 11, and the second end 414b of the swing arm body 41b is the end of the swing arm body 41b connected to the rotating shaft mechanism 20b.

[0149] The first end 413b of the swing arm body 41b is connected to the sliding body 42b. Specifically, one end of the sliding body 42b is connected to the first end 413b of the swing arm body 41b, and the other end of the sliding body 42b extends away from the swing arm body 41b. The sliding body 42b is arranged to protrude relative to the second connecting surface 412b of the swing arm body 41b. The sliding body 42b is disposed through the slide groove 11 and is capable of reciprocating within the slide groove 11 in the second direction Y and in a direction opposite to the second direction Y, thereby driving the swing arm body 41b to move relative to the second cover plate 240. Specifically, when the handle 50b is engaged with the second cover plate 240, the sliding body 42b is capable of moving within the slide groove 11 until it abuts against the first side wall 111, locking the second cover plate 240 with the chassis 210 and thus fixing the second cover plate 240 with the chassis 210. When the handle 50b is disengaged from the second cover 240, the sliding body 42b can move within the chute 11 until it abuts against the second side wall 112, thereby unlocking the second cover 240 from the chassis 210, and even detaching the second cover 240 from the chassis 210. Alternatively, the sliding body 42b can move within the chute 11 until it is located between the first side wall 111 and the second side wall 112, thereby unlocking the second cover 240 from the chassis 210, and even detaching the second cover 240 from the chassis 210. It should be noted that the second cover 240 and the chassis 210 can also be in an unlocked state when the sliding body 42b is at any position between the first side wall 111 and the second side wall 112 in the chute 11, and this is not strictly limited in this embodiment.

[0150] The second end 414b of the swing arm body 41b is provided with a second mounting hole 418b, which extends through the second end 414b of the swing arm body 41b. In other words, the second mounting hole 418b is a through hole through which the hinge mechanism 20b can be inserted. When the connecting swing arm 40b is mounted to the chassis 210, the second mounting hole 418b of the connecting swing arm 40b can communicate with the first receiving cavity 2441 of the second cover plate 240 through the first mounting hole 2443 of the first receiving cavity 2441. The second mounting hole 418b of the connecting swing arm 40b corresponds to the first mounting hole 2443 of the first receiving cavity 2441, thereby enabling the hinge mechanism 20b to be inserted through the second cover plate 240 and the connecting swing arm 40b.

[0151] The second end 414b of the swing arm body 41b is further provided with a through slot 419b. The through slot 419b extends through the second end 414b of the swing arm body 41b along the third direction Z. The through slot 419b is located on the side of the second mounting hole 418b away from the first end 413b, and the through slot 419b is spaced apart from the second mounting hole 418b. The through slot 419b is used to allow one end of the first elastic member 23b of the rotating shaft mechanism 20b described below to pass through. The through slot 419b can limit the torsional movement of the first elastic member 23b and provide a motion trajectory for the torsional movement of the first elastic member 23b. In other words, one end of the first elastic member 23b can slide within the through slot 419b. For example, the through slot 419b is arc-shaped.

[0152] Please refer to Figure 8 、 Figure 28 and Figure 29 , Figure 28 yes Figure 25 The structure diagram of the rotating shaft mechanism 20b shown is installed on the second cover plate 240 at an angle. Figure 29 yes Figure 25 The structure diagram of the rotating shaft mechanism 20b shown is another angle diagram of the installation on the second cover plate 240.

[0153] The hinge mechanism 20b is disposed through the second cover plate 240. Specifically, one end of the hinge mechanism 20b is located within the first receiving cavity 2441 of the first boss 2440, and the hinge mechanism 20b extends through the first mounting hole 2443 of the first receiving cavity 2441. When the second cover plate 240 is fixedly connected to the housing 220, the other end of the hinge mechanism 20b is located within the chassis 210. The centerline C4 of the hinge mechanism 20b is parallel to the third direction Z, and the hinge mechanism 20b is capable of rotating about the centerline C4.

[0154] Please refer to Figure 26 、 Figure 28 and Figure 30 , Figure 30 yes Figure 26The exploded schematic diagram of the rotating shaft mechanism 20b is shown. The rotating shaft mechanism 20b may include a shaft seat 21b, a first shaft body 22b and a first elastic member 23b.

[0155] The shaft seat 21b is provided through the first mounting hole 2443 of the first receiving cavity 2441 and the second mounting hole 418b for connecting the swing arm 40b. Specifically, the shaft seat 21b may include a carrier 211b, a first connecting portion 212b, and a second connecting portion 213b. There may be two first connecting portions 212b, each connected to one side of the carrier 211b and located within the first receiving cavity 2441. The two first connecting portions 212b are spaced apart in the first direction X, and the gap between the two first connecting portions 212b is used to accommodate a portion of the handle 50b. Each first connecting portion 212b is provided with a first through hole 214b, which extends through the first connecting portion 212b along the first direction X. The first through hole 214b is used to allow the second shaft 30b to pass therethrough.

[0156] The carrier 211b is located in the first receiving cavity 2441 and covers the first mounting hole 2443. In this arrangement, when the shaft seat 21b is installed in the first mounting hole 2443 of the first receiving cavity 2441, the carrier 211b can act as a stop, thereby stopping the first connecting portion 212b of the shaft seat 21b in the first receiving cavity 2441, preventing the first connecting portion 212b of the shaft seat 21b from passing through the first mounting hole 2443 and extending into the interior of the chassis 210.

[0157] The second connecting portion 213b is connected to the other side of the carrier 211b and extends through the first mounting hole 2443 of the first receiving cavity 2441. When the second cover 240 is fixedly connected to the housing 220, the second connecting portion 213b extends into the interior of the chassis 210. Specifically, the second connecting portion 213b is located within the first mounting hole 2443 and the second mounting hole 418b of the first receiving cavity 2441. With this arrangement, the second cover 240 and the connecting arm 40b can cooperate to accommodate and secure the shaft seat 21b, ensuring good connection stability and reliability between the shaft seat 21b, the second cover 240, and the connecting arm 40b.

[0158] See also Figure 31 , Figure 31 yes Figure 30 The diagram shows the structure of the shaft base 21b at an angle. The shaft base 21b also has a through-hole 216b located between the second connecting portion 213b and the carrier 211b. The through-hole 216b extends from the side of the second connecting portion 213b away from the carrier 211b toward the carrier 211b, passing through the second connecting portion 213b and the carrier 211b. The through-hole 216b is used to connect to the first shaft 22b.

[0159] Please refer to Figure 28 and Figure 32 , Figure 32 It is along Figure 28 The cross-sectional view taken along section line BB is shown. The second connecting portion 213b is inserted into the first mounting hole 2443 of the first receiving cavity 2441. The portion of the second connecting portion 213b extending out of the first mounting hole 2443 of the first receiving cavity 2441 is fixedly connected to the second end 414b of the connecting swing arm 40b. This arrangement secures the shaft seat 21b to the connecting swing arm 40b, allowing the shaft seat 21b to move in conjunction with the connecting swing arm 40b.

[0160] That is, when the shaft seat 21b rotates counterclockwise about the centerline C4 of the rotating shaft mechanism 20b, the second end 414b of the connecting swing arm 40b can be driven by the second connecting portion 213b to rotate counterclockwise about the centerline C4 of the rotating shaft mechanism 20b, thereby causing the sliding body 42b located at the first end 413b of the connecting swing arm 40b to move within the sliding groove 11 of the first cover plate 230 in a direction opposite to the second direction Y. Since the sliding body 42b of the connecting swing arm 40b moves within the sliding groove 11 of the first cover plate 230 in a direction opposite to the second direction Y, the shaft seat 21b can be driven by the sliding action of the connecting swing arm 40b to move relative to the first cover plate 230 in the first direction X, thereby driving the second cover plate 240 fixedly connected to the shaft seat 21b to move relative to the first cover plate 230 in the first direction X. The reverse is also true.

[0161] Under this setting, the connection relationship between the rotating shaft mechanism 20b and the connecting swing arm 40b can be utilized to transmit the rotational motion of the rotating shaft mechanism 20b to the connecting swing arm 40b, and the rotational motion can be converted into sliding motion in the slide groove 11 through the sliding body 42b on the connecting swing arm 40b, so as to utilize the sliding action of the connecting swing arm 40b to complete the forward and backward movement of the second cover plate 240 relative to the first cover plate 230, so as to achieve the purpose of opening and closing the second cover plate 240 relative to the first cover plate 230 and the box body 220.

[0162] Please continue reading Figure 32The first shaft 22b passes through the second mounting hole 418b of the connecting swing arm 40b and extends into the through hole 216b of the shaft seat 21b. The first shaft 22b is fixedly connected to the shaft seat 21b. The first elastic member 23b is wound around the first shaft 22b. One end of the first elastic member 23b can be fixed to the second end 414b of the connecting swing arm 40b. The other end of the first elastic member 23b can pass through the through groove 419b of the second end 414b of the swing arm body 41b. The other end of the first elastic member 23b can slide in the through groove 419b. When the second cover 240 is fixedly connected to the box body 220, the first shaft 22b is located in the chassis 210, and the first elastic member 23b is located in the chassis 210. On the one hand, the provision of the first elastic member 23b can limit the rotation angle of the hinge mechanism 20b, thereby preventing the hinge mechanism 20b from rotating too much, thereby reducing the working reliability of the locking assembly 100. On the other hand, the first elastic member 23b can be provided so that the rotating shaft mechanism 20b can perform multiple torsional movements due to the elastic restoring effect of the first elastic member 23b, thereby improving reliability.

[0163] Please refer to Figure 26 、 Figure 32 and Figure 33 , Figure 22 yes Figure 10 The handle 50b is mounted on the second cover plate 240. Figure 33 yes Figure 26 A schematic structural diagram of the handle 50b is shown at an angle.

[0164] The handle 50b is connected to the second cover plate 240 via the hinge mechanism 20b, with at least a portion of the handle 50b located outside the chassis 210. The handle 50b is capable of rotating about the centerline C4 of the hinge mechanism 20b, driving the first end 413b of the connecting swing arm 40b to slide within the slide groove 11 in a direction opposite to the second direction Y, thereby moving the second cover plate 240 relative to the first cover plate 230 and the housing 220 in the first direction X, thereby unlocking the second cover plate 240 from the first cover plate 230 and the housing 220. The handle 50b may include a handle body 51b, a handle holding portion 52b, a third shaft 53b, and a second elastic member (not shown). One end of the handle body 51b is located in the gap between the two first connecting portions 212b in the shaft seat 21b, and the other end of the handle body 51b is rotationally connected to the handle holding portion 52b via the third shaft 53b. The second shaft 30b passes through one end of the handle body 51b and the two first connecting portions 212b, thereby allowing the third shaft 53a to pass through the handle 50b and the rotating shaft mechanism 20b. It should be noted that the above description of the handle 50b is merely a brief description of the connection relationship between the various structures in the handle 50b. The basic structure of the various components in the handle 50b, the connection relationship between the components, and the connection relationship between the components and components outside the assembly can all refer to the relevant design of the handle 50a in the first embodiment. The detailed structure and position arrangement of the components of the handle 50b and the handle 50a can be the same or different, and this embodiment does not specifically limit this.

[0165] In one possible implementation, please refer to Figure 33 and Figure 34 , Figure 34 yes Figure 33The diagram shows an assembly structure of the handle 50b, the rotating shaft mechanism 20b, and the connecting swing arm 40b. In this embodiment, the handle 50b may further include a protrusion 55b connected to the bottom of the handle body 51b. The protrusion 55b protrudes relative to the handle body 51b, with the protrusion 55b protruding toward the bottom plate 2210 of the housing 220. The protrusion 55b can contact the second end 414b of the connecting swing arm 40b. It is understood that when the handle 50b rotates clockwise about the centerline C4 of the rotating shaft mechanism 20b, the second end 414b of the connecting swing arm 40b can be driven by the rotating shaft mechanism 20b to rotate clockwise about the centerline C4 of the rotating shaft mechanism 20b. When the handle 50b rotates counterclockwise about the centerline C4 of the rotating shaft mechanism 20b, the second end 414b of the connecting swing arm 40b can be driven by the rotating shaft mechanism 20b to rotate counterclockwise about the centerline C4 of the rotating shaft mechanism 20b. A protrusion 55b is provided on the handle body 51b. When the handle 50b rotates around the center line C4 of the rotating shaft mechanism 20b until the protrusion 55b contacts the second end 414b of the swing arm body 41b, the handle 50b is restricted from further rotation through the interaction between the second end 414b of the swing arm body 41b and the protrusion 55b. That is, the protrusion 55b can limit the rotation angle of the handle 50b, thereby avoiding a reduction in unlocking / locking efficiency due to excessive rotation of the handle 50b, and has good reliability.

[0166] Please refer again Figure 29 The second cover plate 240 may further include a stopper 2450 disposed on the first surface 2413 of the second cover plate body 2410. The stopper 2450 protrudes from the first surface 2413 of the second cover plate body 2410 and is capable of contacting the first end 413b of the connecting swing arm 40b. For example, the stopper 2450 may be a hook.

[0167] It is understood that when the handle 50 rotates clockwise about the centerline C4 of the rotating shaft mechanism 20b, the second end 414b of the connecting swing arm 40b can be driven by the rotating shaft mechanism 20b to rotate clockwise about the centerline C4 of the rotating shaft mechanism 20b, thereby driving the first end 413b of the connecting swing arm 40b to rotate clockwise about the centerline C4 of the rotating shaft mechanism 20b. When the handle 50 rotates counterclockwise about the centerline C4 of the rotating shaft mechanism 20b, the second end 414b of the connecting swing arm 40b can be driven by the rotating shaft mechanism 20b to rotate counterclockwise about the centerline C4 of the rotating shaft mechanism 20b, thereby driving the first end 413b of the connecting swing arm 40b to rotate counterclockwise about the centerline C4 of the rotating shaft mechanism 20b. A stop portion 2450 is provided on the second cover plate body 2410, which can prevent the first end 413b of the connecting swing arm 40b from rotating around the center line C4 of the rotating shaft mechanism 20b until the first end 413b of the connecting swing arm 40b contacts the stop portion 2450 and cannot continue to rotate, so that the first end 413b of the connecting swing arm 40b can rotate within the range limited by the stop portion 2450, avoiding excessive rotation of the first end 413b of the connecting swing arm 40b, and playing a good limiting role.
