Description

Technical Field

[0001] This application relates to the field of mobile energy storage technology, and in particular to a housing structure and energy storage device. Background Technology

[0002] Energy storage devices are equipped with removable covers to conceal certain components, such as antenna modules. These covers can be removed when it is necessary to expose these components. In related technologies, the covers are detachable and assembled using snap-fit ​​mechanisms. However, this method is difficult to disassemble, and the snaps are prone to breakage during disassembly, making reassembly and disassembly inconvenient. Utility Model Content

[0003] In view of this, this application provides a housing structure and energy storage device that facilitates repeated disassembly and assembly of the cover plate.

[0004] One embodiment of this application provides a housing structure. The housing structure includes a housing body, a cover plate, and a locking assembly. The cover plate is detachably disposed on one side of the housing body along a first direction. The locking assembly includes a fixing buckle, a limiting groove, a resilient buckle, and a buckle mating member. One of the fixing buckle and the limiting groove is disposed on the housing body, and the other is disposed on the cover plate. The fixing buckle is inserted into the limiting groove to constrain the relative position of the housing body and the cover plate in a first direction and a second direction. One of the resilient buckle and the buckle mating member is disposed on the housing body, and the other is disposed on the cover plate. The resilient buckle and the buckle mating member engage to constrain the relative position of the housing body and the cover plate in a third direction. The resilient buckle is configured to elastically deform to release the resilient buckle and the buckle mating member from engagement, allowing the housing body and the cover plate to move relative to each other in a third direction, and simultaneously causing the fixing buckle to disengage from the limiting groove. The first direction, the second direction, and the third direction intersect each other.

[0005] Through the engagement of the fixed buckle and the limiting slot, as well as the engagement of the elastic buckle and the buckle fitting, the cover plate and the shell body are constrained in three directions, thus ensuring the stable assembly of the cover plate to the shell body. The elastic buckle deforms under force and separates from the buckle fitting, releasing the constraint on the cover plate and shell body in the third direction. By moving the cover plate along this third direction, the fixed buckle and the limiting slot can be separated, completing the disassembly of the cover plate and shell body. This disassembly method helps avoid damage to the engaging components, allowing the cover plate to be reassembled and disassembled again, facilitating multiple disassembly and reassembly of the cover plate.

[0006] In some embodiments of this application, in a direction perpendicular to the first direction, a cover plate covers the housing body with a resilient latch and a latching engagement member. The housing structure is configured to allow an unlocking member to move from outside the housing structure to the resilient latch. The resilient latch is configured to elastically deform under pressure from the unlocking member, thereby disengaging the resilient latch and the latching engagement member.

[0007] The connection structure of the elastic clip and its mating parts can be concealed between the shell body and the cover plate. This helps prevent the elastic clip from being accidentally disengaged from the mating parts due to external environmental contact, thus improving the stability of the shell body and cover plate. When it is necessary to remove the cover plate, simply insert the unlocking part between the shell body and the cover plate and press the elastic clip to disengage it from the mating parts. The operation is simple, avoids damage to the elastic clip, and facilitates the reassembly and disassembly of the cover plate.

[0008] In some embodiments of this application, the resilient snap-fit ​​is provided with a guide ramp. The guide ramp is configured to allow the unlocking member to move along the guide ramp and to receive the force of the unlocking member, so that the resilient snap-fit ​​disengages from the snap-fit ​​member in a direction perpendicular to a third direction.

[0009] By setting a guide slope, the unlocking component can release the snap-fit ​​connection between the elastic buckle and the buckle mating component as it is inserted between the shell body and the cover plate, simplifying the operation process.

[0010] In some embodiments of this application, the snap-fit ​​element is provided with a through hole. The through hole is configured to allow the unlocking element to extend into it as it moves along the guide ramp, thereby pushing the resilient snap away from the snap-fit ​​element.

[0011] The snap-fit ​​component needs to block the elastic snap to fix the shell body and the cover plate together. The unlocking component passes through the through hole, allowing it to pass over the snap-fit ​​component and press against the elastic snap. The snap-fit ​​component, by having a through hole, facilitates the passage of the unlocking component, so that when restricting the elastic snap, the snap-fit ​​component does not need to be offset to one side to avoid the unlocking component, which helps to improve the stability of the snap-fit ​​component and the elastic snap.

[0012] In some embodiments of this application, a guide groove is formed between the shell body and the cover plate. One end of the guide groove communicates with the outside of the shell structure, and the other end of the guide groove leads to a through hole. The guide groove is configured to allow the unlocking member to pass through and guide the unlocking member to act on the resilient latch.

[0013] The guide groove can guide the movement path of the unlocking part when it extends into the shell body and the cover plate. On the one hand, it can guide the unlocking part to accurately pass through the through hole and press the elastic buckle. On the other hand, it can constrain the relative position of the unlocking part, which helps to prevent the unlocking part from being deflected by the reaction force of the elastic buckle and thus failing to stably release the snap connection between the elastic buckle and the buckle mating part.

[0014] In some embodiments of this application, the elastic buckle is a positive stop buckle fitting in the third direction. Furthermore, the housing body is fixed by a negative stop cover and / or a limiting groove in the third direction.

[0015] The elastic buckle only needs to consider the stop limit on one side of the third upward direction, which makes it easier to reduce the size of the elastic buckle structure. This makes it easier for the elastic buckle to achieve elastic deformation and limit, which helps to improve the service life of the elastic buckle and makes it easier for the cover plate to be reassembled and disassembled again.

[0016] In some embodiments of this application, the elastic buckle includes a hook portion, an elastic arm, and a connecting portion. The hook portion and the buckle mating member engage. The elastic arm connects the hook portion and the connecting portion. The elastic arm is configured to elastically deform to move the hook portion, thereby disengaging the hook portion and the buckle mating member. The connecting portion is located on the housing body or cover plate.

[0017] The elastic arm swings through elastic deformation, causing the hook to move closer to or away from the snap-fit ​​component, thus achieving engagement or disengagement. The elastic snap-fit, with this structure, is easy to assemble.

[0018] In some embodiments of this application, the resilient snap-fit ​​includes a snap-fit ​​block and an elastic element. The snap-fit ​​block is slidably disposed in a direction perpendicular to a third direction. The elastic element is configured to apply an elastic force toward the snap-fit ​​mating member to the snap-fit ​​block, so that the snap-fit ​​block and the snap-fit ​​mating member engage.

[0019] The elastic element pushes the latching block to slide through elastic deformation, thereby engaging or disengaging the latching block and the latching mating parts. With this structure, the elastic latching mechanism provides stable engagement and disengagement, and facilitates the disassembly and reassembly of the cover plate.

[0020] In some embodiments of this application, the resilient snap-fit ​​also includes a limiting member. The limiting member is located on the side of the snap-fit ​​block facing the snap-fit ​​mating member and stops the snap-fit ​​block to prevent it from detaching from the housing body or cover plate.

[0021] By constraining the position of the latching block by limiting the position of the latching block, the maximum extension position of the latching block is limited when the cover plate is removed from the shell body. On the one hand, this can prevent the latching block from falling off without needing to reassemble the latching block. On the other hand, it can prevent the latching block from protruding too much and hindering the reassembly of the cover plate.

[0022] One embodiment of this application provides an energy storage device. The energy storage device includes a functional module and a housing structure as described in any of the above embodiments. The functional module is disposed within the main body of the housing structure.

[0023] The cover plate can be stably fixed to the housing body to protect the functional modules. At the same time, the cover plate is easy to remove from the housing body and easy to reassemble into the housing body, which facilitates the maintenance or replacement of the functional modules.

[0037] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0040] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0041] Energy storage devices are equipped with removable covers to conceal certain components, such as antenna modules. When these components need to be exposed, such as for maintenance, the cover can be removed. In related technologies, the cover is detachable and assembled using snap-fit ​​mechanisms, but this is difficult to remove, and the snaps are prone to breakage during removal, making reassembly and disassembly inconvenient.

[0042] Embodiments of this application provide a housing structure. The housing structure includes a housing body, a cover plate, and a locking assembly. The cover plate is detachably disposed on one side of the housing body along a first direction. The locking assembly includes a fixed latch, a limiting slot, a resilient latch, and a latching engagement member. One of the fixed latch and the limiting slot is disposed on the housing body, and the other is disposed on the cover plate. The fixed latch is inserted into the limiting slot to constrain the relative position of the housing body and the cover plate in a first direction and a second direction. One of the resilient latch and the latching engagement member is disposed on the housing body, and the other is disposed on the cover plate. The resilient latch and the latching engagement member engage to constrain the relative position of the housing body and the cover plate in a third direction. The resilient latch is configured to elastically deform to disengage the resilient latch and the latching engagement member, allowing the housing body and the cover plate to move relative to each other in a third direction, and simultaneously causing the fixed latch to disengage from the limiting slot. The first direction, the second direction, and the third direction intersect each other.

[0043] Through the engagement of the fixed buckle and the limiting slot, as well as the engagement of the elastic buckle and the buckle fitting, the cover plate and the shell body are constrained in three directions, thus ensuring the stable assembly of the cover plate to the shell body. The elastic buckle deforms under force and separates from the buckle fitting, releasing the constraint on the cover plate and shell body in the third direction. By moving the cover plate along this third direction, the fixed buckle and the limiting slot can be separated, completing the disassembly of the cover plate and shell body. This disassembly method helps avoid damage to the engaging components, allowing the cover plate to be reassembled and disassembled again, facilitating multiple disassembly and reassembly of the cover plate.

[0044] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] See Figure 1 This application provides a housing structure 100 and an energy storage device 200. The housing structure 100 is used to protect the modules or components inside the energy storage device 200.

[0046] In some embodiments, the energy storage device 200 is used for home backup power, production unit backup power, and outdoor work, outdoor recreation, etc.

[0047] In some embodiments, the energy storage device 200 includes a functional module (not shown) and a housing structure 100. The functional module is disposed within the housing structure 100. The functional module includes a battery cell module and / or a power conversion module. The battery cell module is used to store electrical energy. The power conversion module is used to control the AC / DC conversion of the output current of the battery cell module.

[0048] The energy storage device 200, which is equipped with both a battery cell module and a power conversion module, can be a small portable power supply, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0049] Alternatively, the power conversion module can be omitted. The energy storage device 200 without a power conversion module can be used independently. The energy storage device 200 without a power conversion module typically only outputs DC power. When used independently, the energy storage device 200 without a power conversion module can be used in conjunction with an energy storage device 200 with a power conversion module as a power system providing additional battery capacity.

[0050] Alternatively, the battery cell module can be omitted. The energy storage device 200 without a battery cell module can be used independently. The energy storage device 200 without a battery cell module is used in conjunction with the energy storage device 200 without a power conversion module to achieve AC / DC conversion control of the output current of the energy storage device 200 without a power conversion module.

[0051] See Figure 1 and Figure 2 In some embodiments, the housing structure 100 includes a housing body 10 and a cover plate 20. The functional modules of the energy storage device 200 are disposed within the housing body 10. The cover plate 20 is detachably disposed on one side of the housing body 10. The cover plate 20 can constrain the functional modules within the housing body 10 and protect the functional modules.

[0052] In some embodiments, a first direction is defined as the direction parallel to the distribution of the cover plate 20 and the shell body 10. A second direction is defined as perpendicular to the first direction, and a third direction is defined as perpendicular to the first direction, with the first, second, and third directions being mutually perpendicular. The first direction is the direction parallel to X in the illustration, the second direction is the direction parallel to Y in the illustration, and the third direction is the direction parallel to Z in the illustration. For ease of reference to the illustration, the first direction will be referred to as "first direction X", the second direction as "second direction Y", and the third direction as "third direction Z" in the following text.

[0053] See Figures 2 to 4 In some embodiments, the housing structure 100 further includes a snap-fit ​​assembly 30. The snap-fit ​​assembly 30 is used to achieve a detachable connection between the housing body 10 and the cover plate 20. The cover plate 20 can be stably fixed to the housing body 10 to protect the functional module, while the cover plate 20 is easy to remove from the housing body 10 and easy to reassemble to the housing body 10, facilitating the maintenance or replacement of the functional module.

[0054] In some embodiments, the engaging assembly 30 includes a fixed latch 31, a limiting slot 32, an elastic latch 33, and a latching engagement member 34. One of the fixed latch 31 and the limiting slot 32 is disposed on the housing body 10, and the other on the cover plate 20. The fixed latch 31 is inserted into the limiting slot 32 to constrain the relative position of the housing body 10 and the cover plate 20 in a first direction X and a second direction Y. One of the elastic latch 33 and the latching engagement member 34 is disposed on the housing body 10, and the other on the cover plate 20. The elastic latch 33 and the latching engagement member 34 engage to constrain the relative position of the housing body 10 and the cover plate 20 in a third direction Z. The elastic latch 33 is configured to elastically deform to disengage the elastic latch 33 and the latching engagement member 34, allowing the housing body 10 and the cover plate 20 to move relative to each other in the third direction Z, and simultaneously causing the fixed latch 31 to disengage from the limiting slot 32.

[0055] Through the engagement of the fixed buckle 31 and the limiting slot 32, and the engagement of the elastic buckle 33 and the buckle fitting 34, the cover plate 20 and the shell body 10 can be constrained in three directions, thereby ensuring the stable assembly of the cover plate 20 to the shell body 10. The elastic buckle 33 deforms elastically under force and separates from the buckle fitting 34, releasing the constraint on the cover plate 20 and the shell body 10 in the third direction Z. Then, by moving the cover plate 20 along the third direction Z, the fixed buckle 31 and the limiting slot 32 can be separated, thus completing the disassembly of the cover plate 20 and the shell body 10. This disassembly method helps avoid damage to the engaging components 30, allowing the cover plate 20 to be reassembled and disassembled again, facilitating multiple disassembly and assembly of the cover plate 20, and aiding in the maintenance of the functional modules within the energy storage device 200.

[0056] See Figure 2, Figure 4 and Figure 5 In some embodiments, the retaining clip 31 has a hook-like structure. The limiting groove 32 has a cavity extending in a third direction Z. The hook-like structure of the retaining clip 31 can enter the cavity of the limiting groove 32 in a first direction X, and the hook-like structure of the retaining clip 31 can move in the cavity of the limiting groove 32 in a third direction Z, thereby hooking the hook-like structure of the retaining clip 31 onto the limiting groove 32, thereby limiting the shell body 10 and the cover plate 20 in the first direction X. Furthermore, the portion of the retaining clip 31 within the limiting groove 32 can be constrained by the limiting groove 32 in a second direction Y, thereby limiting the shell body 10 and the cover plate 20 in the second direction Y.

[0057] In some embodiments, the elastic buckle 33 stops the buckle engagement member 34 in the positive direction of the third direction Z. The housing body 10 stops the buckle 31 in the opposite direction of the third direction Z, with the cover plate 20 and / or the limiting groove 32 stopping the buckle 31 in the opposite direction of the third direction Z. Here, the third direction Z is a bidirectional direction; "positive direction of the third direction Z" and "opposite direction of the third direction Z" are used only to indicate the opposite engagement relationship of the above structures in the third direction Z.

[0058] The elastic buckle 33 only needs to consider the stop limit on one side in the third direction Z, which makes it easier to reduce the size of the elastic buckle 33, thereby making it easier for the elastic buckle 33 to achieve elastic deformation and limit, which is beneficial to improving the service life of the elastic buckle 33 and making it easier for the cover plate 20 to be reassembled and disassembled again.

[0059] It is understood that in some embodiments, the mating structure of the fixing buckle 31 and the limiting groove 32 is provided on both sides of the shell body 10 and the cover plate 20 along the second direction Y, so as to improve the stability of the fixing cover plate 20.

[0060] The engaging structure of the elastic buckle 33 and the buckle mating part 34 is located on one side of the shell body 10 and the cover plate 20 along the third direction Z, which facilitates the release of the engaging connection of the elastic buckle 33 and the buckle mating part 34 and simplifies the steps of removing the cover plate 20. Furthermore, the engaging structure of the elastic buckle 33 and the buckle mating part 34 is located at the middle position in the second direction Y on this side, which is convenient for operation and provides stable positioning.

[0061] When the cover plate 20 needs to be disassembled or reassembled, the third direction Z is parallel to the direction of gravity, and the elastic buckle 33 is located on the upper side of the shell structure 100 in the direction of gravity.

[0062] In some embodiments, in a direction perpendicular to the first direction X, the cover plate 20 covers the housing body 10 with a resilient latch 33 and a latching engagement member 34. The housing structure 100 is configured to allow the unlocking member 300 to move from outside the housing structure 100 to the resilient latch 33 between the housing body 10 and the cover plate 20. The resilient latch 33 is configured to elastically deform under pressure from the unlocking member 300, thereby disengaging the resilient latch 33 and the latching engagement member 34.

[0063] The connection structure between the elastic buckle 33 and the buckle mating part 34 can be hidden between the shell body 10 and the cover plate 20, which helps to prevent the elastic buckle 33 from being accidentally disengaged from the buckle mating part 34 due to external environmental contact, thus improving the stability of fixing the shell body 10 and the cover plate 20. When it is necessary to remove the cover plate 20, the unlocking part 300 is inserted between the shell body 10 and the cover plate 20 to press the elastic buckle 33, which can disengage the elastic buckle 33 and the buckle mating part 34. The operation is simple and can avoid damage to the elastic buckle 33, making it convenient for the cover plate 20 to be reassembled and disassembled again.

[0064] In other embodiments, the resilient buckle 33 may be exposed in the housing body 10 and / or cover plate 20 in a direction perpendicular to the first direction X, and the user may directly press the resilient buckle 33 to release the snap connection between the resilient buckle 33 and the snap-fit ​​member 34.

[0065] In some embodiments, the resilient snap-fit ​​33 is provided with a guide ramp 331. The guide ramp 331 is configured to allow the unlocking member 300 to move along the guide ramp 331 and to receive the force of the unlocking member 300, so that the resilient snap-fit ​​33 disengages from the snap-fit ​​member 34 in a direction perpendicular to the third direction Z. The guide ramp 331 can be an arc surface or a plane.

[0066] By setting the guide slope 331, when the unlocking part 300 is inserted between the shell body 10 and the cover plate 20, the snap connection between the elastic buckle 33 and the buckle mating part 34 can be released with the insertion action, simplifying the operation process.

[0067] Understandably, in some embodiments, the guide slope 331 is inclined relative to the third direction Z so that when the cover plate 20 and the shell body 10 move relative to each other in the third direction Z, the snap-fit ​​component 34 moves along the guide slope 331 and causes the elastic snap 33 to elastically deform, so that the snap-fit ​​component 34 can pass over the elastic snap 33.

[0068] Understandably, in some embodiments, the guide ramp 331 is also inclined relative to the first direction X or the second direction Y. When the guide ramp 331 is inclined relative to the first direction X, the housing mechanism is configured to allow the unlocking member 300 to move between the housing body 10 and the cover plate 20 along the third direction Z and to move along the guide ramp 331, so that the resilient latch 33 is disengaged from the latching member 34 along the first direction X. When the guide ramp 331 is inclined relative to the second direction Y, the housing structure 100 is configured to allow the unlocking member 300 to move between the housing body 10 and the cover plate 20 along the second direction Y or the third direction Z and to move along the guide ramp 331, so that the resilient latch 33 is disengaged from the latching member 34 along the second direction Y.

[0069] In some embodiments, the snap-fit ​​member 34 is provided with a through hole 341. The through hole 341 is configured to allow the unlocking member 300 to extend into it as it moves along the guide ramp 331 to push the resilient snap 33 away from the snap-fit ​​member 34.

[0070] The latching component 34 needs to block the elastic latch 33 to fix the shell body 10 and the cover plate 20 together. The unlocking component 300 passes through the through hole 341, allowing it to pass over the latching component 34 and press the elastic latch 33. The latching component 34, by providing the through hole 341, facilitates the passage of the unlocking component 300, ensuring that it does not need to be offset to one side to avoid the unlocking component 300 when restricting the elastic latch 33. This improves the stability of the latching engagement between the latching component 34 and the elastic latch 33. Furthermore, by providing the through hole 341, when the cover plate 20 is removed and moved relative to it, the latching component 34 can avoid the unlocking component 300. This means the unlocking component 300 only needs to press the elastic latch 33 until it can avoid it, without needing to further press the elastic latch 33 until it needs to avoid the unlocking component 300.

[0071] In some embodiments, a guide groove 11 is formed between the shell body 10 and the cover plate 20. One end of the guide groove 11 communicates with the outside of the shell structure 100, and the other end of the guide groove 11 communicates with the through hole 341. The guide groove 11 is configured to allow the unlocking member 300 to pass through and guide the unlocking member 300 to act on the elastic buckle 33. The guide groove 11 can be formed separately on the shell body 10, separately on the cover plate 20, or formed by the shell body 10 and the cover plate 20 in conjunction. The shell body 10 and the cover plate 20 can form the guide groove 11 by protruding flanges or by recesses.

[0072] The guide groove 11 can guide the movement path of the unlocking member 300 when it extends into the shell body 10 and the cover plate 20. On the one hand, it can guide the unlocking member 300 to accurately pass through the through hole 341 and press the elastic buckle 33. On the other hand, it can constrain the relative position of the unlocking member 300, which helps to prevent the unlocking member 300 from being deflected by the reaction force of the elastic buckle 33 and thus failing to stably release the snap connection between the elastic buckle 33 and the buckle mating member 34.

[0073] Understandably, in some embodiments, the unlocking member 300 is a rod-shaped, column-shaped, or strip-shaped structure, so as to extend between the shell body 10 and the cover plate 20 and press the elastic buckle 33.

[0074] See Figure 4 and Figure 5 In some embodiments, the elastic latch 33 includes a hook portion 332, an elastic arm 333, and a connecting portion 334. The hook portion 332 engages with the latching member 34. The elastic arm 333 connects the hook portion 332 and the connecting portion 334. The elastic arm 333 is configured to elastically deform to move the hook portion 332, thereby disengaging the hook portion 332 from the latching member 34. The connecting portion 334 is located on the housing body 10 or the cover plate 20. The hook portion 332 has a guide slope 331. Specifically, when the latching member 34 is located on the cover plate 20, the connecting portion 334 is located on the housing body 10; when the latching member 34 is located on the housing body 10, the connecting portion 334 is located on the cover plate 20.

[0075] The elastic arm 333 swings through elastic deformation, thereby moving the hook portion 332 closer to or away from the snap-fit ​​component 34 to achieve engagement or disengagement with the snap-fit ​​component 34. The elastic snap-fit ​​33 adopts the above structure, which is easy to assemble.

[0076] Understandably, in some embodiments, the elastic arm 333 has a U-shaped structure, which is easily compressed and undergoes elastic deformation, making it convenient for the elastic buckle 33 and the buckle mating part 34 to release from the engagement.

[0077] It is understood that in some embodiments, the snap-fit ​​part, the elastic arm 333 and the connecting part 334 are integrally formed structures, which are easy to achieve elastic deformation and easy to assemble.

[0078] See Figure 6 and Figure 7In some embodiments, the resilient latch 33 includes a latching block 335 and an elastic element 336. The latching block 335 is slidably disposed in a direction perpendicular to the third direction Z. The elastic element 336 is configured to apply an elastic force toward the latching engagement member 34 to the latching block 335 so that the latching block 335 and the latching engagement member 34 engage. The latching block 335 is provided with a guide ramp 331. The shell body 10 or the cover plate 20 is provided with a groove extending perpendicular to the third direction Z to accommodate the latching block 335 and guide the latching block 335 to slide. When the latching engagement member 34 is disposed on the cover plate 20, the latching block 335 is slidably disposed on the shell body 10, and the elastic element 336 is disposed between the latching block 335 and the shell body 10; when the latching engagement member 34 is disposed on the shell body 10, the latching block 335 is slidably disposed on the cover plate 20, and the elastic element 336 is disposed between the latching block 335 and the shell body 10. For example, the elastic element 336 is a spring.

[0079] The elastic element 336 pushes the latching block 335 to slide through elastic deformation, thereby engaging or disengaging the latching block 335 and the latching mating part 34. The elastic latch 33, with the above structure, provides stable engagement and disengagement, and facilitates the disassembly and reassembly of the cover plate 20.

[0080] In some embodiments, the elastic buckle 33 further includes a limiting member 337. The limiting member 337 is located on the side of the buckle block 335 facing the buckle mating member 34 and stops the buckle block 335 to prevent the buckle block 335 from disengaging from the shell body 10 or the cover plate 20. Specifically, when the buckle block 335 is slidably disposed on the shell body 10, the limiting member 337 is disposed on the shell body 10 and stops the buckle block 335 on the side facing the cover plate 20; when the buckle block 335 is slidably disposed on the cover plate 20, the limiting member 337 is disposed on the cover plate 20 and stops the buckle block 335 on the side facing the shell body 10.

[0081] By constraining the position of the latching block 335 by the limiting member 337, the maximum extension position of the latching block 335 is limited when the cover plate 20 is removed from the shell body 10. On the one hand, this can prevent the latching block 335 from falling off without reassembling the latching block 335. On the other hand, it can prevent the latching block 335 from protruding too much and hindering the reassembly of the cover plate 20.

[0082] In some embodiments, the limiting member 337 is fixed by bolt connection to improve the stability of the limiting member 337. In other embodiments, the limiting member 337 can be snap-fit ​​fixed for easy disassembly and assembly of the snap-fit ​​block 335.

[0083] See Figure 2 , Figure 4 and Figure 5 In some embodiments, the cover plate 20 is installed and removed in the following manner:

[0084] When installing the cover plate 20, insert the fixing buckle 31 into the limiting slot 32 along the first direction X, and move the cover plate 20 along the third direction Z so that the fixing buckle 31 hooks into the limiting slot 32 until the elastic buckle 33 and the buckle mating part 34 are engaged, and the cover plate 20 is installed.

[0085] When disassembling the cover plate 20, the unlocking part 300 is inserted between the shell body 10 and the cover plate 20 along the third direction Z, and as it is inserted, it pushes the elastic buckle 33 to retract in the direction perpendicular to the third direction Z, so that the elastic buckle 33 and the buckle mating part 34 are disengaged. Then, the cover plate 20 is moved along the third direction Z, and the fixing buckle 31 is removed from the limiting buckle, and the disassembly of the cover plate 20 is completed.

[0086] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
