[0058] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0059] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0060] See also Figure 1 The present application first provides a shell structure 100, which can be applied to electronic devices. The electronic device may include a shell structure 100 and an electronic device, and the electronic device is built into the shell structure 100. The shell structure 100 itself can be opened to allow staff to perform maintenance or wiring operations on the electronic devices inside the shell structure 100. In addition, the shell structure 100 has the characteristic of maintaining good sealing after repeated opening and closing, effectively reducing the risk of external factors (such as water and particulate matter) invading the shell structure 100 and affecting the normal operation of the device.

[0061] See also Figure 1 , Figure 2 and Figure 3 In the example of this embodiment, the electronic device is an inverter device 1000, which includes a housing structure 100 and an inverter 200. The inverter 200 has a connection terminal 201, and the connection terminal 201 is used to connect with other devices outside the inverter device 1000. The number of inverters 200 can be greater than or equal to 2, that is, the electronic device can be an integrated electronic device.

[0062] The shell structure 100 includes a shell 10, a sealing ring 20, a sealing plate 30 and a panel 40, wherein the shell 10 is provided with a receiving chamber 11, and the receiving chamber 11 is used to receive the inverter 200. A wiring port 12 is provided on one side of the shell 10, and the wiring port 12 is connected to the receiving chamber 11. The wiring port 12 is used for the connection terminal 201 of the inverter 200 to be exposed in the receiving chamber 11. The sealing ring 20 is distributed around the wiring port 12. The sealing plate 30 blocks the wiring port 12, and the sealing plate 30 and the shell 10 cooperate to extrude the sealing ring 20, and the sealing plate 30 is detachably connected to the shell 10. The panel 40 is covered on the sealing plate 30, and the panel 40 is detachably connected to the shell 10.

[0063] In this way, the sealing plate 30 blocks the wiring port 12 and is sealed with the housing 10 through the sealing ring 20 to prevent water and particles outside the housing 10 from entering the housing 10 through the wire interface. The panel 40 shields the sealing plate 30 to ensure the integrity of the appearance of the housing 10 and further prevent water and particles outside the housing 10 from entering the housing 10.

[0064] When the inverter 200 needs to be wired, the staff can sequentially remove the panel 40 and the sealing plate 30 to expose the wiring port 12 to the panel 40 and the sealing plate 30, and then wire the connection terminal 201 through the wiring port 12. After the wiring is completed, the staff can sequentially install the sealing plate 30 and the panel 40 to allow the panel 40 and the sealing plate 30 to re-close the wiring port 12.

[0065] It can be understood that since the sealing plate 30 only needs to cover the connection port 12 and does not need to cover the entire structure of the housing 10, the overall volume of the sealing plate 30 can be designed to be smaller (relative to the cover plate in the related art), thereby reducing the overall volume of the sealing plate 42, which is not easy to deform during the disassembly process to ensure the sealing stability between the sealing plate 30 and the housing 10. In addition, the panel 40 can cover the sealing plate 30 to achieve a secondary sealing effect, further improving the sealing performance of the housing structure 100, and reducing the risk of external factors (such as water and particulate matter) invading the interior of the housing structure 100 and affecting the normal operation of the device.

[0066] In some embodiments, the housing 10 includes a bottom shell 50 and a front shell 60, wherein the bottom shell 50 is a rectangular parallelepiped as a whole, and the bottom shell 50 is provided with a receiving groove for accommodating various electronic devices, and the front shell 60 is covered on the notch of the receiving groove, so that a receiving cavity 11 is formed between the bottom shell 50 and the front shell 60. The sealing ring 20, the sealing plate 30 and the panel 40 are all arranged on the front shell 60. The front shell 60 is detachably connected to the bottom shell 50, and the detachable connection method includes but is not limited to bolting. In actual applications, when the staff performs operations such as maintenance and installation of electronic devices inside the shell structure 100 that require a large space, the receiving cavity 11 can be opened by disassembling the front shell 60 and the bottom shell 50. Compared with opening the wiring port 12, this method can obtain a larger operating space to facilitate the staff to complete the corresponding operation.

[0067] See also Figure 2 and Figure 4In some embodiments, a recessed groove 61 is formed on one side of the front shell 60 away from the bottom shell 50, and the recessed groove 61 is connected to the side of the front shell 60. The bottom wall of the recessed groove 61 is provided with a wiring port 12, and the wiring port 12 penetrates the front shell 60 along a first direction. Exemplarily, the first direction is the thickness direction of the housing 10, that is, the Y-axis direction in the figure. The wiring port 12 is arranged in the middle of the recessed groove 61. It can be understood that the position of the wiring port 12 can be configured according to the actual position of the terminal 201, and the present application does not limit this.

[0068] In some embodiments, the recess 61 is adapted to the panel 40. When the panel 40 is fixed to the front shell 60, the panel 40 is accommodated in the recess 61, and the sides and surfaces of the panel 40 can be flush with the sides and surfaces of the front shell 60 to ensure the overall appearance integrity of the shell structure 100.

[0069] In some embodiments, the sealing ring 20 is made of an elastic material such as rubber. The shape of the sealing ring 20 matches the shape of the wiring port 12, and the inner ring area of ​​the sealing ring 20 is larger than the opening area of ​​the wiring port 12. Exemplarily, the wiring port 12 is rectangular as a whole, and the sealing ring 20 is also rectangular as a whole, and the length and width of the sealing ring 20 are larger than the length and width of the wiring port 12, so that the sealing ring 20 can cover the outer edge contour distribution of the wiring port 12.

[0070] In some embodiments, the cross section of the sealing ring 20 is annular, so that a through groove is formed inside the sealing ring 20. The through groove structure of the sealing ring 20 increases the deformation range of the sealing ring 20 and improves the sealing performance between the sealing plate 30 and the front shell 60.

[0071] The sealing ring 20 is provided with a convex point on one side facing the sealing plate 30. When the sealing plate 30 is pressed against the sealing ring 20, the convex point can increase the contact area between the sealing ring 20 and the sealing plate 30, further improving the sealing performance between the sealing plate 30 and the front shell 60.

[0072] In some embodiments, the front shell 60 is provided with a mounting groove 62, and the sealing plate 30 is received in the mounting groove 62. Exemplarily, the mounting groove 62 is formed by the bottom wall depression of the paving groove 61, and the mounting groove 62 is distributed in a ring shape around the wiring port 12, and the shape of the mounting groove 62 is adapted to the shape of the sealing plate 30, and the mounting groove 62 has a positioning function for the sealing plate 30, thereby improving the installation stability of the sealing plate 30.

[0073] In some embodiments, the front shell 60 is provided with a sealing groove 63, and the sealing ring 20 is partially embedded in the sealing groove 63. Exemplarily, the sealing groove 63 is formed by the bottom wall depression of the mounting groove 62, and the sealing groove 63 is distributed in an annular shape around the wiring port 12, and the shape of the sealing groove 63 is adapted to the shape of the sealing ring 20. The groove depth of the sealing groove 63 is less than the thickness of the sealing ring 20, one side of the sealing ring 20 is embedded in the sealing groove 63, and the other side of the sealing ring 20 is exposed at the notch of the sealing groove 63 to contact the sealing plate 30. On the one hand, the sealing groove 63 has a positioning effect on the sealing ring 20 to prevent the sealing ring 20 from falling off by itself without human action, and on the other hand, it can increase the contact area between the sealing ring 20 and the front shell 60, and further improve the sealing performance between the sealing plate 30 and the front shell 60.

[0074] In some embodiments, the overall area of ​​the sealing plate 30 is larger than the outer ring area of ​​the sealing ring 20 , so that the sealing plate 30 can cover the outer ring of the sealing ring 20 , ensuring that the sealing plate 30 can completely cover the wiring port 12 and contact all parts of the sealing ring 20 .

[0075] See also Figure 2 and Figure 5 In some embodiments, the sealing plate 30 includes a main body 31, a pressure plate 32 and a plurality of mounting portions 33, wherein the shape of the main body 31 corresponds to the shape of the wiring port 12, and the main body 31 is directly opposite to the wiring port 12. The pressure plate 32 is distributed around the main body 31. The plurality of mounting portions 33 are distributed along the circumference of the pressure plate 32, and the mounting portions 33 are detachably connected to the housing 10.

[0076] Exemplarily, the main body 31 is rectangular as a whole, the pressure plate portion 32 is distributed along the outer periphery of the main body 31, and the mounting portion 33 is formed by the pressure plate portion 32 protruding in a direction away from the main body 31. The main body 31, the pressure plate portion 32 and the mounting portion 33 are integrally formed. The shapes of the pressure plate portion 32 and the mounting portion 33 are adapted to the shape of the mounting groove 62, and the pressure plate portion 32 and the mounting portion 33 can be accommodated in the mounting groove 62 and form a positioning match with the front shell 60.

[0077] It can be understood that the sealing plate 30 is fixed to the housing 10 through multiple mounting parts 33, presses the sealing ring 20 through the pressure plate part 32, and shields the wiring port 12 through the main body part 31 and the pressure plate part 32, thereby realizing the basic functions of the sealing plate 30.

[0078] In some embodiments, the mounting portion 33 is the connection point between the sealing plate 30 and the outer shell 10, and can also serve as the main force point for the pressure plate portion 32 to squeeze the sealing ring 20. Multiple mounting portions 33 can enhance the squeezing effect of the pressure plate portion 32 on the sealing ring 20 at various points on the circumference, thereby preventing the pressure plate portion 32 and the sealing ring 20 from causing a gap due to improper cooperation.

[0079] In some embodiments, the mounting portion 33 is detachably connected to the front shell 60, and the detachable connection method is: bolted and fixed by fixing bolts. A through-hole structure is opened in the middle of the mounting portion 33, and the fixing bolts are passed through the mounting portion 33 and threadedly connected to the front shell 60 to fix the front shell 60 and the sealing plate 30. When the sealing plate 30 needs to be removed, the staff can unscrew the fixing bolts from the mounting portion 33; when the sealing plate 30 needs to be installed, the staff can reinsert the fixing bolts into the mounting portion 33 and the front shell 60.

[0080] It is worth noting that in the example of this embodiment, the detachable connection method between the mounting portion 33 and the front shell 60 is bolted, and in other embodiments, the detachable connection method between the mounting portion 33 and the front shell 60 may also be snap-on, interference fit, pin connection, etc., as long as the effect of detachable connection can be achieved, and this application does not impose any restrictions on this.

[0081] In some embodiments, the main body 31 is recessed relative to the pressure plate 32, and a bending section 34 is formed at the connection between the main body 31 and the pressure plate 32. Exemplarily, the main body 31 is recessed relative to the pressure plate 32 in a direction close to the wiring port 12, so that the main body 31 and the pressure plate 32 are not coplanar, and the connection between the main body 31 and the pressure plate 32 is subjected to a bending transition process to form a bending section 34.

[0082] It can be understood that the bending section 34 can enhance the connection strength between the pressure plate portion 32 and the main body portion 31 and the overall mechanical strength of the sealing plate 30, reduce the probability of deformation of the sealing plate 30 during disassembly and assembly, and thereby reduce the risk of the pressure plate portion 32 and the sealing ring 20 not being able to fully press against each other, thereby improving the service life and sealing performance.

[0083] On the other hand, the main body 31 is recessed in the direction of the access wiring port 12. On the basis of strengthening the strength of the sealing plate 30 and preventing the sealing plate 30 from deforming, the wiring port 12 can provide a certain storage space for the main body 31, prevent spatial interference between the main body 31 and the panel 40, and improve space utilization.

[0084] See also Figure 5 and Figure 6 In some embodiments, the panel 40 is provided with a limit member 41 and a connecting member 43, wherein the limit member 41 and the connecting member 43 are respectively provided on both sides of the panel 40, the limit member 41 is used to connect the sealing plate 30, and the connecting member 43 is used to connect the housing 10. Exemplarily, the limit member 41 and the connecting member 43 are respectively located on both sides of the panel 40 in the second direction, and the second direction is the width direction of the housing 10, that is, the Z-axis direction in the figure.

[0085] The sealing plate 30 is provided with a hook member 35, which is engaged with the limiting member 41 along a first direction to limit the panel 40 in the first direction, and the first direction is perpendicular to the plane where the wiring port 12 is located. The connecting member 43 is detachably connected to the housing 10 to limit the panel 40 in a second direction.

[0086] It can be understood that on the basis that the panel 40 is fixed to the outer shell 10 through the connecting member 43, the sealing plate 30 limits the panel 40 through the snap-fit ​​cooperation between the hook member 35 and the limiting member 41, thereby improving the installation stability of the panel 40. At the same time, the fixed connection between the connecting member 43 and the outer shell 10 is used to prevent the hook member 35 and the limiting member 41 from detaching due to non-human force.

[0087] On the other hand, the detachable fixing structure of the panel 40 is arranged on the connecting member 43 instead of the limiting member 41, which reduces the influence of the stress generated during the disassembly and assembly of the panel 40 on the sealing plate 30 and reduces the risk of deformation of the sealing plate 30.

[0088] See also Figure 6 and Figure 7 In some embodiments, the hook member 35 includes a first end 351 and a second end 352, wherein the first end 351 of the hook member 35 extends along the first direction and is connected to the sealing plate 30, and the second end 352 of the hook member 35 extends along the second direction. Exemplarily, the hook member 35 is integrally formed with the sealing plate 30, and the hook member 35 can be formed by a bending process. The first end 351 of the hook member 35 points to the panel 40 along the first direction, and the second end 352 of the hook member 35 is bent toward the second direction to form a hook-shaped structure. There are multiple hook members 35, and the multiple hook members 35 are spaced apart along the length direction of the sealing plate 30. In the example of this embodiment, the number of hook members 35 is 2, and the two hook members 35 are distributed corresponding to the two ends of the sealing plate 30.

[0089] The limiting member 41 is provided with a limiting hole 411, and the position of the limiting hole 411 corresponds to the position of the hook member 35. The limiting hole 411 penetrates the limiting member 41 along the second direction, and the second end 352 of the hook member 35 is plugged into the limiting hole 411 along the second direction, so that the second end 352 and the limiting member 41 form a snap fit in the first direction.

[0090] Exemplarily, the stopper 41 is integrally formed with the panel 40, and the stopper 41 is formed by protruding from one side of the panel 40 toward the direction close to the sealing plate 30, and the stopper 41 is provided with a plurality of stopper holes 411, and the plurality of stopper holes 411 are respectively provided corresponding to the plurality of hook members 35. In the example of this embodiment, the number of the stopper holes 411 is 2, and the two stopper holes 411 correspond to the position distribution of the second ends 352 of the two hook members 35.

[0091] When removing the panel 40, the staff can first remove the connecting member 43 from the housing 10, and then apply force to the panel 40 to move the panel 40 along the second direction and away from the hook member 35, so that the limiting member 41 is separated from the hook member 35, and the hook member 35 is engaged with the limiting member 41. When installing the panel 40, the staff can first move the panel 40 along the second direction and push it toward the hook member 35, so that the second end 352 of the hook member 35 enters the limiting hole 411 of the limiting member 41 to form a locking connection, and then install and fix the connecting member 43 to the housing 10.

[0092] In this way, during the disassembly and assembly process of the panel 40 , the staff only needs to disassemble and assemble the connecting member 43 , and does not need to use additional tools to remove the limiting member 41 , thereby improving the disassembly and assembly efficiency.

[0093] In some embodiments, the connecting member 43 is disposed on a side of the panel 40 away from the stopper 41 in the second direction, the connecting member 43 extends along the first direction, and a through hole structure is disposed in the middle of the connecting member 43. The housing 10 is provided with a threaded hole 51, and the threaded hole 51 is used for matching with a disassembly screw (not shown in the figure) for installation, wherein the threaded hole 51 is used for the disassembly screw to pass through the connecting member 43 along the second direction and be threadedly connected to the housing 10.

[0094] Exemplarily, the connecting member 43 is integrally formed with the panel 40, the connecting member 43 is formed by extending from one side of the panel 40 toward the direction close to the housing 10, and the end of the connecting member 43 away from the panel 40 extends to the side of the bottom shell 50. The bottom shell 50 is provided with a threaded hole 51 corresponding to the connecting member 43, and the disassembly screw is penetrated through the connecting member 43 along the second direction and is threadedly connected to the threaded hole 51 of the housing 10.

[0095] When disassembling and assembling the panel 40, the staff can remove or install the connector 43 on the bottom shell 50 by screwing the disassembly screws, thereby realizing the overall disassembly and assembly of the panel 40. The installation method is simple and convenient, and the disassembly and assembly efficiency is improved.

[0096] On the other hand, the panel 40 in this embodiment is clamped to the sealing plate 30 through the stopper 41, and the sealing plate 30 is fixed to the front shell 60, so that the panel 40 and the front shell 60 are relatively fixed, and at the same time, the panel 40 is bolted to the bottom shell 50 through the connecting member 43, so that the panel 40 and the bottom shell 50 are relatively fixed. In this way, the panel 40 can form a connection structure between the front shell 60 and the bottom shell 50 to maintain the fixation of the two, thereby improving the installation stability between the bottom shell 50 and the front shell 60.

[0097] In some embodiments, there are multiple connectors 43, and the multiple connectors 43 are spaced apart along the length direction of the panel 40. In the example of this embodiment, the number of connectors 43 is 2, and the two connectors 43 are distributed corresponding to the two ends of the two panels 40. Correspondingly, there are multiple threaded holes 51, and the multiple threaded holes 51 correspond to the position distribution of the multiple connectors 43.

[0098] It is worth noting that in the example of this embodiment, the detachable connection method between the connecting member 43 and the bottom shell 50 is bolted, and in other embodiments, the detachable connection method between the connecting member 43 and the bottom shell 50 may also be snap-on, interference fit, pin connection, etc., as long as the effect of detachable connection can be achieved, and this application does not impose any restrictions on this.

[0099] See also Figure 5 and Figure 6 In some embodiments, a positioning member 42 is provided on the side of the panel 40 facing the housing 10. The housing 10 is provided with a positioning slot 64, and the positioning member 42 is plugged into the positioning slot 64. The positioning slot 64 allows the positioning member 42 to be plugged in along a first direction, and the panel 40 is positioned along a third direction by plugging and fitting. The third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. Exemplarily, the third direction is the length direction of the housing 10, that is, the X-axis direction in the figure. There are multiple positioning members 42, and the multiple positioning members 42 are distributed at intervals. In the example of this embodiment, the number of positioning members 42 is 4, and the four positioning members 42 are distributed in a matrix. Correspondingly, the housing 10 is provided with multiple positioning slots 64, and the multiple positioning slots 64 correspond to the position distribution of the multiple positioning members 42.

[0100] The positioning effect of the positioning slot 64 on the panel 40 can improve the installation stability of the panel 40. At the same time, during the installation of the panel 40, the position of the limit member 41 can be aligned with the corresponding hook member 35, and the position of the connecting member 43 can be aligned with the corresponding threaded hole 51, thereby improving the installation efficiency of the panel 40.

[0101] See also Figure 5 , Figure 6 and Figure 8 In some embodiments, the positioning member 42 includes a first section 421 and a second section 422. The first section 421 of the positioning member 42 extends along the first direction and is connected to the panel 40, and the second section 422 of the positioning member 42 extends along the second direction. Exemplarily, the positioning member 42 is integrally formed with the panel 40, and the positioning member 42 is L-shaped as a whole. The first section 421 of the positioning member 42 points to the front shell 60 along the first direction, and the second section 422 of the positioning member 42 points to the hook member 35 along the second direction.

[0102] The positioning slot 64 is adapted to the positioning member 42, and the positioning slot 64 has a first slot body 641 and a second slot body 642 that are connected, wherein the first slot body 641 extends along the first direction, and the first slot body 641 passes through a side of the housing 10 facing the panel 40. The second slot body 642 extends along the second direction. Exemplarily, the positioning slot 64 is provided on a side of the front housing 60 facing the panel 40, and the positioning slot 64 is L-shaped as a whole, and the length of the first slot body 641 in the second direction is greater than the length of the first section 421 in the second direction, and the length of the second slot body 642 in the second direction is greater than the length of the second section 422 in the second direction.

[0103] Thus, when the positioning member 42 is inserted into the positioning slot 64, the positioning member 42 can slide along the second direction in the positioning slot 64. The positioning member 42 has a locked state and an unlocked state that can be switched by sliding.

[0104] When the panel 40 moves along the second direction to a position cooperating with the hook member 35 , the second section 422 can enter the second slot 642 from the first slot 641 , so that the positioning member 42 is engaged with the positioning slot 64 along the first direction. At this time, the positioning member 42 is in a locked state.

[0105] When the panel 40 moves along the second direction to be disengaged from the hook member 35 , the second section 422 is disengaged from the second slot 642 , allowing the positioning member 42 to be disengaged from the positioning slot 644 along the first direction. At this time, the positioning member 42 is in an unlocked state.

[0106] When the panel 40 needs to be removed, the connecting member 43 can be removed from the bottom shell 50 first, and then the panel 40 can be pushed along the second direction to move the panel 40 away from the hook member 35. At the same time, the second section 422 is detached from the second groove 642, and then the panel 40 can be pulled away from the front shell 60 along the first direction.

[0107] When the panel 40 needs to be installed, the panel 40 can be first covered on the front shell 60 so that the second section 422 enters the first groove 641, and then the panel 40 is pushed along the second direction so that the hook member 35 is inserted into the limiting member 41. At the same time, the second section 422 enters the second groove 642 from the first groove 641, and then the connecting member 43 can be fixed to the bottom shell 50.

The housing structure 100 also has a panel 40 and a sealing plate 30, wherein the sealing plate 30 shields and closes the wiring port 12, and the panel 40 covers the sealing plate 30.

[0109] When the inverter 200 needs to be wired, the staff can sequentially remove the panel 40 and the sealing plate 30 to expose the wiring port 12 to the panel 40 and the sealing plate 30, and then wire the connection terminal 201 through the wiring port 12. After the wiring is completed, the staff can sequentially install the sealing plate 30 and the panel 40 to allow the panel 40 and the sealing plate 30 to re-close the wiring port 12.
