Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device including the element. If not conflicting, the features of the embodiments of the present application and the embodiments can be combined with each other, and are all within the protection scope of the present application.

[0054] The present application provides a case, Figure 1 is a structural schematic diagram of the case.

[0055] Specifically, referring to Figure 1 The case includes a box body 20 and a handle device 10 arranged on the box body 20.

[0056] By arranging the handle device 10, the box body 20 can be conveniently disassembled. In specific implementation, an operator can hold the handle device 10, insert the box body 20 into a target installation object in a predetermined direction, so as to realize installation of the box body 20; correspondingly, pull the box body 20 out of the target installation object in the opposite direction of the predetermined direction, so as to realize disassembly of the box body 20.

[0057] It should be noted that the present embodiment does not limit the specific type of the target installation object, and exemplarily, the target installation object can be a protective shell for protecting the box body 20, and can also be a liquid cooling heat dissipation cabinet or air cooling heat dissipation cabinet for heat dissipation of the box body 20.

[0058] It should be noted that the specific type of the box body 20 is not limited in the embodiment, and can be adjusted according to specific requirements. For example, the box body 20 is an electronic device such as a server, a switch, a power supply, etc.

[0059] It can be understood that, Figure 1 only some components included in the case are schematically shown, and the actual shape, actual size, actual position and actual structure of the components are not limited Figure 1 , and the case can also include more or fewer components than Figure 1 .

[0060] Please refer to Figure 6 , the related art provides a handle device of a case, which comprises a locking piece 4 and a handle 2, the handle 2 is rotationally arranged on a case body 1, the locking piece 4 is fixedly arranged on the case body 1, the locking piece 4 has a convex block 5, the handle 2 has a bayonet 3, the convex block 5 is located in the bayonet 3, so as to lock the handle 2 and the case body 1; the handle 2 is configured to move away from the locking piece 4 along the convex direction of the convex block 5 under the action of an external force, so that the bayonet 3 is separated from the convex block 5, and the handle 2 and the case body 1 are unlocked.

[0061] However, the handle 2 will be deformed under the action of the external force, resulting in a reduction in the structural strength of the handle 2.

[0062] In view of the above technical problems, the embodiment of the present application provides a handle device 10 of a case, Figure 2 for Figure 1 structure schematic view of the handle device 10 and the box body 20 in the embodiment, Figure 3 for Figure 2 structure schematic view of the locking mechanism in the embodiment, Figure 4 for Figure 3 internal structure schematic view of the handle device 10, Figure 5 for Figure 3 exploded view of the handle device 10.

[0063] Specifically, please refer to Figure 2 to Figure 5 , the handle device 10 of the case comprises: a handle module 100, the handle module 100 is arranged on a box body 20 of the case in rotation; a lock catch module 200, the lock catch module 200 comprises a clamping piece 210 and a trigger piece 220 connected with each other, the trigger piece 220 is arranged in rotation with the box body 20; a driving module 300, the driving module 300 is arranged on the box body 20, and the driving module 300 moves relative to the box body 20 to push the clamping piece 210 to rotate, so that the clamping piece 210 is switched between a locking state and an unlocking state.

[0064] In the locked state, the clamping piece 210 is clamped with the handle module 100, and the trigger piece 220 has a gap with the handle module 100; in the unlocked state, the clamping piece 210 is separated from the handle module 100, and the trigger piece 220 abuts against the handle module 100 to push the handle module 100 away from the cabinet 20.

[0065] The handle device 10 of the cabinet provided in the embodiment of the present application is provided with the driving module 300 and the locking buckle module 200, the locking buckle module 200 comprises the clamping piece 210 and the trigger piece 220 connected with each other, the trigger piece 220 is rotationally connected with the cabinet 20, when it is needed to disassemble or assemble the cabinet 20, the driving module 300 is moved relative to the cabinet 20, the driving module 300 can contact and push the clamping piece 210 to rotate, so that the clamping piece 210 can be switched from the locked state of being clamped with the handle module 100 to the unlocked state of being separated from the handle module 100, thereby realizing the unlocking of the handle module 100. In this process, the driving module 300 is moved relative to the cabinet 20 under the action of external force, thereby realizing the unlocking of the handle module 100, and the handle module 100 does not directly bear the external force, so that the deformation of the handle module 100 due to the external force can be avoided, thereby effectively avoiding the reduction of the structural strength of the handle module 100.

[0066] Further, by providing the trigger piece 220, the driving module 300 pushes the clamping piece 210 to rotate in the process, which can drive the trigger piece 220 to rotate synchronously, so that the trigger piece 220 can be switched from the state of having a gap with the handle module 100 to the state of abutting against the handle module 100, to push the handle module 100 away from the cabinet 20. In this scenario, the operator does not need to pry the handle module 100 away from the state of being close to the cabinet 20 (the handle module 100 is close to the cabinet 20, which is not convenient for the operator to apply force), but can directly hold the handle module 100 away from the cabinet 20 to take out the handle module 100, thereby reducing the difficulty of taking out the handle module 100.

[0067] The preferred technical solutions of the handle device 10 of the cabinet in the embodiment of the present application will be described below with reference to the accompanying drawings, wherein, Figure 2 For Figure 1 The structural schematic diagram of the connection between the handle device 10 and the cabinet 20, Figure 3 For Figure 2 The structural schematic diagram of the locking mechanism, Figure 4 For Figure 3 The internal structural schematic diagram of the handle device 10, Figure 5 For Figure 3 The exploded view of the handle device 10.

[0068] The related art also provides a handle device of a cabinet, comprising two locking pieces and two handles, the two handles and the two locking pieces are arranged on a cabinet body, and the locking pieces are used for locking or unlocking the handles.

[0069] By setting two handles, the two hands of the operator hold one handle respectively, which is more stable and saves labor; by setting two locking pieces to correspondingly lock or unlock the two handles, it can be ensured that the handles do not occupy more space in the non-working state.

[0070] However, in the above related technology, when the handle needs to be unlocked for disassembly of the case body, the operator needs to operate the locking piece with both hands to correspondingly unlock the handle, and the operation steps are complicated. For example, when disassembling the case body in a small disassembly space, it is necessary to first find the position of one of the locking pieces, operate the locking piece to correspondingly unlock one of the handles, and then take out the handle; then, find the position of the other locking piece, operate the locking piece to correspondingly unlock the other handle, and then take out the handle. In the above disassembly process, at least six steps are required to take out the handle, which leads to complicated operation steps for taking out the handle, and further leads to inconvenient disassembly operation of the case body.

[0071] After the disassembly of the case body is completed, correspondingly, at least six steps are required to lock the handle, which leads to complicated operation steps for locking the handle.

[0072] In view of the above technical problems, please refer to Figure 2 to Figure 5 The handle module 100 includes a first handle assembly 101 and a second handle assembly 102, and the first handle assembly 101 and the second handle assembly 102 are both used for rotating the handle arranged on the box body 20.

[0073] The lock catch module 200 includes a first lock catch assembly 201 and a second lock catch assembly 202, and the trigger 220 of the first lock catch assembly 201 and the trigger 220 of the second lock catch assembly 202 are both used for rotating the handle arranged on the box body 20, the first lock catch assembly 201 is located on one side of the first handle assembly 101, and the second lock catch assembly 202 is located on one side of the second handle assembly 102.

[0074] The drive module 300 is arranged between the first handle assembly 101 and the second handle assembly 102, and the drive module 300 moves relative to the box body 20 to push the clamping piece 210 of the first lock catch assembly 201 and the clamping piece 210 of the second lock catch assembly 202 to rotate in opposite directions.

[0075] The handle device 10 of the chassis provided in this embodiment is configured with a first handle assembly 101 and a second handle assembly 102, both of which can be used for assembling and disassembling the chassis 20. Specifically, an operator can hold the first handle assembly 101 and the second handle assembly 102 with both hands respectively, inserting the chassis 20 into the target installation object along a preset direction to achieve installation of the chassis 20; correspondingly, the chassis 20 can be pulled out from the target installation object in the opposite direction to achieve disassembly of the chassis 20. In the above process, because the operator holds the first handle assembly 101 and the second handle assembly 102 with both hands respectively, the grip is more stable and requires less effort.

[0076] By setting the first locking component 201 to lock or unlock the first handle component 101, and by setting the second locking component 202 to lock or unlock the second handle component 102, it can be ensured that the first handle component 101 and the second handle component 102 do not occupy too much space when not in operation.

[0077] By positioning the drive module 300 between the first handlebar assembly 101 and the second handlebar assembly 102, that is, the first handlebar assembly 101, the drive module 300, and the second handlebar assembly 102 are positioned along the length of the drive module 300 (e.g., ...). Figure 1 and Figure 2 The components are arranged sequentially in the Y direction, with the first locking assembly 201 positioned on one side of the first handle assembly 101 and the second locking assembly 202 positioned on one side of the second handle assembly 102. When the drive module 300 moves relative to the housing 20 (e.g., along the Y direction), the first locking assembly 201 is positioned on one side of the first handle assembly 101, and the second locking assembly 202 is positioned on one side of the second handle assembly 102. Figure 1 and Figure 2 The drive module 300 moves in the height direction Z), and the drive module 300 can simultaneously act on the latching member 210 of the first latching assembly 201 and the latching member 210 of the second latching assembly 202, causing them to rotate in opposite directions (e.g., Figure 2 The two latching parts 210 rotate counterclockwise and clockwise respectively, allowing them to simultaneously switch from the locked to the unlocked state, thus achieving synchronous unlocking of the first handle assembly 101 and the second handle assembly 102. In this process, the operator only needs to first locate the locking module 200 and then simultaneously unlock the first handle assembly 101 and the second handle assembly 102 by operating the locking module 200 with both hands. Then, the first handle assembly 101 and the second handle assembly 102 can be removed respectively. Compared to related technologies where two locking parts are operated separately with both hands to unlock the two handles, the handle device of the chassis provided in this embodiment reduces the operation of unlocking one handle assembly, simplifying the unlocking steps of the first handle assembly 101 and the second handle assembly 102.

[0078] After the box 20 is disassembled, the first handle assembly 101 and the second handle assembly 102 can be simultaneously locked by operating the lock buckle module 200, so that the locking operation of the first handle assembly 101 and the second handle assembly 102 is simple.

[0079] In addition, the driving module 300 is arranged between the first handle assembly 101 and the second handle assembly 102, which not only realizes the synchronous unlocking function, but also optimizes the space layout of the entire handle device 10, so that the first handle assembly 101 and the second handle assembly 102 are respectively located on the two sides of the driving module 300, and the mutual interference between the first handle assembly 101 and the second handle assembly 102 is effectively avoided.

[0080] In some embodiments, referring to Figure 2 The first end of the clamping piece 210 is close to the driving module 300, and the second end of the clamping piece 210 is away from the driving module 300. The distance between the first ends of the two clamping pieces 210 is less than the distance between the second ends of the two clamping pieces 210.

[0081] In the embodiment, the distance between the first ends of the two clamping pieces 210 is less than the distance between the second ends of the two clamping pieces 210, so that the direction in which the two clamping pieces 210 approach each other is inclined relative to the driving module 300. When the driving module 300 pushes the clamping piece 210, the driving module 300 is more likely to push the two clamping pieces 210 to rotate, and the unlocking difficulty of the handle module 100 can be reduced.

[0082] In some embodiments, referring to Figure 4 and Figure 5 The lock buckle module 200 comprises a reset piece 230. One end of the reset piece 230 is connected with the box 20, and the other end of the reset piece 230 is connected with the clamping piece 210.

[0083] In the locked state, the reset piece 230 releases the elastic force and acts on the clamping piece 210, so that the clamping piece 210 is clamped with the handle module 100.

[0084] In the embodiment, one end of the reset piece 230 is connected with the box 20, and the other end of the reset piece 230 is connected with the clamping piece 210. When the reset piece 230 releases the elastic force, the reset piece 230 can push the clamping piece 210 to the position of clamping with the handle module 100 without external intervention, so that the handle module 100 is always in the locked state without active unlocking, and the safety of the handle module 100 is improved.

[0085] In addition, in the unlocked state, the clamping piece 210 is separated from the handle module 100, and the reset piece 230 can be compressed by the clamping piece 210.

[0086] In some specific embodiments, the reset member 230 is a torsion spring, which has good elastic performance and durability, so that the locking performance of the lock catch module 200 is good.

[0087] In some embodiments, please refer to Figure 4 and Figure 5 , the lock catch module 200 further comprises a fixing member 240, the fixing member 240 is connected with the clamping member 210, the fixing member 240 extends along the clamping member 210 towards the reset member 230, and the other end of the reset member 230 abuts against the fixing member 240.

[0088] In the present embodiment, by arranging the fixing member 240, the fixing member 240 is connected with the clamping member 210, the fixing member 240 extends along the clamping member 210 towards the reset member 230, and the other end of the reset member 230 abuts against the fixing member 240, so that the fixing member 240 serves as a bridge connecting the clamping member 210 and the reset member 230, which facilitates the clamping member 210 to compress the reset member 230, and also facilitates the reset member 230 to exert elastic force on the clamping member 210, so that the clamping member 210 is stably clamped with the handle module 100.

[0089] The fixing member 240 extends to a length corresponding to the length of the end of the reset member 230, which can prevent the reset member 230 from being separated from the fixing member 240.

[0090] In some other embodiments, please refer to Figure 4 and Figure 5 , the lock catch module 200 further comprises a rotating shaft 250, the rotating shaft 250 is arranged on the box body 20; the trigger member 220 has a shaft hole 221, the rotating shaft 250 is inserted into the shaft hole 221, and the trigger member 220 can rotate relative to the rotating shaft 250.

[0091] In the present embodiment, the rotating shaft 250 has a restraining effect on the trigger member 220 and the clamping member 210, which can ensure that the trigger member 220 and the clamping member 210 can only rotate around the rotating shaft 250 as the rotation axis, and will not be offset relative to the rotating shaft 250.

[0092] In some specific embodiments, please refer to Figure 4 and Figure 5 , one of the clamping member 210 and the handle module 100 has a protrusion 211, and the other of the clamping member 210 and the handle module 100 has a recess 110, the protrusion 211 is clamped into or separated from the recess 110, so that the clamping member 210 is clamped with or separated from the handle module 100.

[0093] In the embodiment, the cooperation of the protrusion 211 and the groove 110 can achieve a stable locking effect. When the protrusion 211 is clamped into the groove 110, a close connection is formed between the clamping piece 210 and the handle module 100, so that the handle module 100 cannot rotate freely, and accidental opening of the handle module 100 in an unlocked state can be effectively prevented, thereby improving the safety of the handle module 100.

[0094] In addition, the design of the protrusion 211 and the groove 110 makes the locking and unlocking process simple and intuitive. When the driving module 300 acts on the clamping piece 210, only the protrusion 211 needs to be disengaged from the groove 110 to achieve unlocking, which is not only convenient to operate, but also less prone to failure.

[0095] Further, referring to Figure 3 to Figure 5 , the side of the clamping piece 210 close to the driving module 300 is arc-shaped.

[0096] By setting the side of the clamping piece 210 close to the driving module 300 as an arc surface, the arc surface is a gradual contact surface, and when the driving module 300 contacts the clamping piece 210, the arc surface can more effectively convert the pushing force into a rotating force to improve the pushing efficiency.

[0097] In some embodiments, referring to Figure 4 and Figure 5 , the driving module 300 includes a guide 310 arranged on the box 20, and a pushing piece 320 connected with the guide 310 and abutting against the lock catch module 200.

[0098] In the embodiment, when the lock catch module 200 includes the first lock catch assembly 201 and the second lock catch assembly 202, the pushing piece 320 is arranged to abut against the first lock catch assembly 201 and the second lock catch assembly 202, and the pushing piece 320 is arranged along the length direction of the driving module 300, so that the overall length of the pushing piece 320 is not less than the distance between the first lock catch assembly 201 and the second lock catch assembly 202. Thus, the length of the surface of the pushing piece 320 that can be used to bear external force is longer, so that the operator can easily apply external force to the pushing piece 320, thereby reducing the unlocking difficulty of the lock catch module 200.

[0099] In other embodiments, referring to Figure 4 and Figure 5 , the locking mechanism further includes at least two guide columns 440 arranged on the box 20.

[0100] The guide 310 has at least two guide holes 330, and the guide columns 440 are correspondingly inserted into the guide holes 330 and can move along the hole walls of the guide holes 330 to move the driving module 300 relative to the box 20.

[0101] In some specific embodiments (not shown in the embodiment), the two sides of the guide column 440 are matched with the hole wall of the guide hole 330.

[0102] In the embodiment, the number of the guide column 440 and the guide hole 330 is two, the shape of the two sides of the guide column 440 is matched with the shape of the hole wall of the guide hole 330, the guide column 440 can constrain the movement of the driving module 300, so that the driving module 300 can only move in a specific direction (for example Figure 1 and Figure 2 the height direction Z of the driving module 300). Exemplarily, the guide column 440 is a quadrangular prism, a hexagonal prism or an octagonal prism, the two sides of the quadrangular prism, the hexagonal prism and the octagonal prism are planes, so that the two sides can be closely attached to the hole wall of the guide hole 330, thereby limiting the rotation of the driving module 300 and limiting the movement of the driving module 300 along its length direction.

[0103] In some other specific embodiments, please continue to refer to Figure 4 and Figure 5 , the number of the guide hole 330 is more than three, each guide hole 330 is arranged non-linearly; the number of the guide column 440 is more than three, the guide column 440 is correspondingly inserted into the guide hole 330.

[0104] In the embodiment, by setting at least three guide columns 440 and a corresponding number of guide holes 330, a multi-point guide structure is formed. Since each guide hole 330 and each guide column 440 are arranged non-linearly, when the guide column 440 is correspondingly inserted into the guide hole 330, the multi-point guide can better constrain the movement trajectory of the driving module 300, so that it can move smoothly along the predetermined path, and can effectively prevent the driving module 300 from tilting or deviating during movement.

[0105] It should be noted that the structure of the guide column 440 is not specifically limited in the embodiment, and can be set according to requirements. Exemplarily, the guide column 440 is a cylinder, a triangular prism or a quadrangular prism.

[0106] In some other embodiments, please refer to Figure 2 to Figure 5 , the locking mechanism further includes a housing 400, the housing 400 includes: a first cover 410 and a second cover 420, the first cover 410 and the second cover 420 are both used to be arranged on the box body 20; a connecting piece 430, the connecting piece 430 connects the second cover 420 and the first cover 410; the locking module 200 is rotationally arranged between the first cover 410 and the second cover 420, and the driving module 300 is movably arranged between the first cover 410 and the second cover 420.

[0107] In the embodiment, the first cover 410 and the second cover 420 are arranged along the width direction (for example, the X direction in the drawing) of the driving module 300, and the locking module 200 and the driving module 300 are arranged between the first cover 410 and the second cover 420, so that the first cover 410 and the second cover 420 can protect the locking module 200 and the driving module 300. Specifically, the first cover 410 and the second cover 420 form a physical barrier for the locking module 200 and the driving module 300, so that the locking module 200 and / or the driving module 300 can be prevented from being damaged due to collision with foreign matters. Figure 1

[0108] It should be noted that the specific connection manner of the first cover 410 and the box 20 and the specific connection manner of the second cover 420 and the box 20 are not limited in the embodiment, and for example, the specific connection manner can be riveting, screwing or welding.

[0109] In some specific embodiments, please refer to Figure 4 and Figure 5 The reset member 230 is rotationally connected to the connecting member 430, and the connecting member 430 can constrain the reset member 230 to ensure that the reset member 230 can only perform a rotating action, thereby ensuring that the clamping member 210 and the handle module 100 are stably clamped.

[0110] In some specific embodiments, please continue to refer to Figure 4 and Figure 5 At least one of the first cover 410 and the second cover 420 has an abutting member 450, and the abutting member 450 is used to abut against the reset member 230 to achieve installation of the reset member 230.
