Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a housing assembly and a water purifier. Background Technology

[0002] With the development of the times, people have increasingly higher requirements for drinking water quality, and water purifiers have been recognized and purchased by most people. Water purifiers can purify tap water or water in a water tank to provide users with high-quality clean water. Water purifiers on the market can include under-sink water purifiers and built-in water purifiers.

[0003] Various components of a water purifier, such as filter cartridges, electronic control boards, and piping, are installed within the housing assembly. Currently, housing assemblies on the market are typically composed of multiple parts, which are interconnected by snap-fits or fasteners to form a cavity for housing the aforementioned components.

[0004] The assembly process is relatively simple because the housing components are connected by snap-fits. However, due to the flexible fit, if the fit is too loose, the housings may separate during transportation or installation; if the fit is too tight, disassembly is difficult during maintenance. Some housing components use fasteners to connect the housings, which can cause significant inconvenience during assembly and maintenance. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide a housing assembly, including a main housing and side plates. The main housing has a mounting opening on its side, and the side plates cover the mounting opening. The main housing and side plates together form a receiving cavity. The main housing has a plug-in portion, and the side plates have plug-in adapter portions corresponding to the plug-in portion. The plug-in portion and the plug-in adapter portion are plugged into each other along a first direction, which is parallel to the plane of the mounting opening. The main housing has a first fastening portion, and the side plates have second fastening portions corresponding to the first fastening portion. The first and second fastening portions are connected to each other by fasteners. In the above technical solution, by providing a plug-in portion on the main housing and a plug-in adapter portion on the side plates, the side plates can be installed to the mounting opening by plugging in. After the side plates are installed, they can only be disassembled in the direction opposite to the first direction. This ensures that the side plates are reliably installed on the main housing and will not loosen in the lateral direction. A small number of fasteners can limit the side plates, preventing them from accidentally moving and falling off in the direction opposite to the first direction. In summary, the use of fasteners and connectors ensures both ease of assembly and maintenance, as well as a reliable connection between the side panels and the main housing.

[0006] For example, the plug-in portion includes a first plug-in portion extending from the edge of the mounting opening beyond the main housing. The plug-in adapter portion includes a first plug-in adapter portion that mates with the first plug-in portion. The side plate includes a side plate body and a flange, which bends and extends from the side plate body toward the main housing so that the flange and the side plate body enclose a corner space. The first plug-in adapter portion is disposed within the corner space. The first plug-in portion extending from the main housing can mate with the first plug-in adapter portion, eliminating the need for the first plug-in adapter portion on the side plate to extend beyond the flange, resulting in a simpler structure.

[0007] Exemplarily, the first insertion adapter includes: a frame connected to the flange and the main housing, and the frame having an insertion port facing the insertion direction for interlocking with the first insertion part; and a guide eave extending from the edge of the insertion port along the insertion direction. The frame can limit the insertion part, and the side plate can only be removed in the lateral direction when the insertion part is withdrawn from the insertion port in the depth direction. When the insertion part is inserted into the insertion port and in place, the guide eave can also support the first protruding end.

[0008] For example, the first insertion portion includes: a first reinforcing rib disposed on the inner surface of the main housing, the first reinforcing rib having a first protruding end that extends beyond the main housing via the edge of the mounting opening; and an insertion portion extending from the first protruding end along an insertion direction that interlocks with the first insertion adapter. Because the reinforcing rib has high strength, forming the first insertion portion with the reinforcing rib ensures that the outer side plate will not loosen even under significant external force. The surface of the insertion portion facing the main housing can abut against the surface of the first insertion adapter, thereby limiting its position in the lateral direction.

[0009] For example, the mounting opening includes: a first edge and a second edge opposite to each other along a second direction, the second direction being perpendicular to the first direction and parallel to the plane where the mounting opening is located; and a third edge and a fourth edge opposite to each other along the first direction, wherein: the insertion portion includes a plurality of first insertion portions disposed on the first edge and the second edge; and a first fastening portion is disposed on the third edge. Thus, the side plate and the main housing have three fixing portions, and the three fixing portions are respectively located at the three edges of the side plate, thereby providing reliable fixing. Furthermore, the structure for fixing using the first insertion portions and the first insertion adapter portions is symmetrically arranged on both sides of the mounting opening, while the structure for fixing using fasteners is arranged on the other side, making the force on the side plate more uniform in the symmetrical direction, while reducing the number of fasteners.

[0010] For example, the first edge and the second edge are the upper and lower edges of the mounting opening, respectively; and the third edge and the fourth edge are the rear and front edges of the mounting opening, respectively. As described above, the portion of the side plate corresponding to the first and second edges is configured as a flange with rounded corners. A first fastening part is provided at the third edge, where the side plate can be constructed as a plane. After the fastener is installed, the nuts and other parts of the fastener will not protrude from the surface of the housing assembly.

[0011] For example, the mounting opening includes a third edge and a fourth edge opposite to each other along a first direction, the third edge and the fourth edge being arranged sequentially along the first direction. The fourth edge is provided with a first stop edge protruding from the mounting opening. When the side panel is installed in place on the main housing, it abuts against the first stop edge. The insertion portion includes a second insertion portion, which is disposed on the inner surface of the first stop edge facing the third edge. Thus, when the side panel is installed in place, all four edge portions are fixed and limited towards the main housing, with almost no gaps. This makes it more suitable for the harsh environment of under-sink areas, and it is less likely to accumulate dirt.

[0012] For example, a snap-fit ​​portion is provided on the inner surface of the first stop, and a snap-fit ​​adapter portion is provided on the side plate. The snap-fit ​​portion and the snap-fit ​​adapter portion snap into each other along a first direction. The snap-fit ​​adapter portion can provide a certain tactile feedback when the side plate is installed in place, and generate a certain resistance when the side plate moves away from the first direction, thereby giving the operator certain feedback so that the operator can confirm that the side plate is correctly installed. At the same time, before the operator installs the fasteners, the snap-fit ​​portion can prevent the side plate from accidentally sliding and causing the first and second insertion portions to separate from their respective insertion adapter portions.

[0013] For example, the snap-fit ​​part is provided with a snap-fit ​​groove, the snap-fit ​​groove having at least a snap-fit ​​opening facing the side plate; the snap-fit ​​adapter part includes: a first side wall and a second side wall, one side of both the first side wall and the second side wall being connected to the inner surface of the side plate, and the other side of the first side wall and the second side wall being spaced apart to form a gap, the gap extending along a first direction, the first side wall, the second side wall and the inner surface of the side plate enclosing to form an insertion cavity, the insertion part being inserted into the insertion cavity along the first direction; and a snap-fit ​​protrusion, the snap-fit ​​protrusion being connected to the inner surface of the side plate within the insertion cavity, wherein: the snap-fit ​​protrusion engages with the snap-fit ​​opening on the snap-fit ​​part within the insertion cavity along the first direction. Through the aforementioned snap-fit ​​protrusion, a tactile feedback can be provided during the installation of the side plate, the snap-fit ​​protrusion can engage with the snap-fit ​​opening, and during this process, the snap-fit ​​groove can elastically deform towards the protruding direction of the snap-fit ​​protrusion, the gap between the first side wall and the second side wall can reduce the rigidity of the snap-fit ​​adapter part, thereby increasing the aforementioned elastic deformation. During the engagement process, the first and second sidewalls can also provide limits in the height and lateral directions to prevent misalignment between the engagement protrusion and the engagement groove. After the engagement protrusion engages with the engagement groove, a certain amount of resistance can be generated when the side plate moves in the opposite direction to the first direction, preventing the side plate from accidentally falling off.

[0014] For example, the snap-fit ​​portion is provided with a snap-fit ​​groove; the snap-fit ​​adapter portion includes a snap-fit ​​protrusion, which engages with the snap-fit ​​groove along a first direction. The snap-fit ​​protrusion has a first side and a second side opposite to each other along the first direction. A first guide slope and a second guide slope are respectively provided on the first side and the second side, wherein the first guide slope and the second guide slope are inclined towards each other and towards the inside of the main housing. Thus, the resistance provided by the snap-fit ​​protrusion is within a suitable range, which can ensure that the side plate is relatively easy to disassemble and install, and can also prevent it from slipping off under its own weight or other external forces.

[0015] For example, the first fastening part includes: a second reinforcing rib disposed on the inner surface of the main housing, the second reinforcing rib having a second protruding end that extends beyond the main housing via a third edge of the mounting opening; and a first fastening hole disposed on the second reinforcing rib. In summary, the thickness of the second reinforcing rib allows it to be embedded in a nut or tapped, and it has sufficient strength.

[0016] For example, the side plate includes a side plate body and a second stop, the second stop being disposed corresponding to the third edge of the mounting opening, and the second stop extending bently from the side plate body toward the main housing. The second fastening portion includes a second fastening hole disposed on the second stop. The second stop can abut against the second protruding end, thereby cooperating with the first stop to further limit the side plate in the depth direction. At the same time, the second stop can structurally improve the strength of the side plate. When the side plate is installed in place, the second stop can cover the second protruding end, making the housing assembly look cleaner. The portion surrounding the second fastening hole on the second stop has sufficient strength to distribute the pressure of the fastener.

[0017] This application also provides a water purifier, including: a filter assembly; and the aforementioned housing assembly, wherein the filter assembly is disposed within the receiving cavity of the housing assembly.

Detailed Implementation

[0031] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0032] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0033] Embodiments of this utility model provide a housing assembly. The housing assembly according to embodiments of this utility model will be described in detail below with reference to the accompanying drawings. The housing assembly of this application is particularly suitable for under-sink water purifiers; in other embodiments, the housing assembly can also be applied to embedded water purifiers.

[0034] Reference Figure 1 and Figure 2 The housing assembly may include a main housing 100 and a side plate 200. The main housing 100 may have a mounting opening 110 on its side, and the side plate 200 may cover the mounting opening 110. The main housing 100 and the side plate 200 together form a receiving cavity 300. The main housing 100 is provided with a plug-in portion 120, and the side plate 200 has a plug-in adapter portion 210 at a position corresponding to the plug-in portion 120. The plug-in portion 120 and the plug-in adapter portion 210 are plugged into each other along a first direction, which is parallel to the plane containing the mounting opening 110. A filter assembly 400, a booster pump, an electronic control board, and other structures may be installed in the receiving cavity 300, which will be further described below.

[0035] For ease of understanding, we will use the normal operating posture of a water purifier as an example. When the water purifier is in normal use, the front panel and rear direction can be referred to as the depth direction, and the direction in which the mounting opening 110 faces can be referred to as the lateral direction. The depth direction, lateral direction, and height direction of the water purifier are all perpendicular to each other. The first direction can be the depth direction, the height direction, or have a certain angle with the depth direction.

[0036] In some embodiments, the side panel 200 can be mounted to the main housing 100 along the height direction, thereby covering the mounting opening 110. The insertion portion 120 can be inserted into the insertion adapter 210 of the side panel 200 along the height direction, thereby limiting the side panel 200 in the lateral direction. Optionally, the side panel 200 can be mounted from top to bottom, so that the main housing 100 of the water purifier does not need to be lifted during disassembly. In other embodiments, the side panel 200 can be mounted along the depth direction. Specifically, for example, the side panel 200 can be mounted from front to back and positioned laterally by the insertion portion 120. The side panel 200 can also be mounted from back to front. In a preferred embodiment, one side of the insertion portion 120 has a gap for accommodating the insertion adapter 210 along the depth direction. The side panel 200 can cover the mounting opening 110 from the lateral direction, while the side panel 200 and the main housing 100 are offset in the depth direction so that the insertion adapter 210 is accommodated in the gap. After the side plate 200 is attached to the main housing 100, it can be moved along the depth direction so that the insertion part 120 can be inserted into the insertion adapter part 210. This allows the side plate 200 to move only a small distance in the depth direction to allow the insertion part 120 and the insertion adapter part 210 to mate with each other. Optionally, the side plate 200 can be installed to the main housing 100 along other directions parallel to the mounting opening 110.

[0037] exist Figure 2 In the illustrated embodiment, the insertion portion 120 may include a hook-shaped structure that can be inserted into a groove in the side plate 200, serving a limiting function through contact with the groove wall. In an embodiment not shown, the insertion adapter portion 210 of the side plate 200 may be constructed as a hook, engaging with a groove in the main housing 100. In summary, when the insertion portion 120 and the insertion adapter portion 210 are properly engaged, they can be appropriately limited in the lateral direction, thereby connecting the side plate 200 and the main housing 100 to each other.

[0038] The main housing 100 may also be provided with a first fastening part 130, and the side plate 200 is provided with a second fastening part 220 at a position corresponding to the first fastening part 130. The first fastening part 130 and the second fastening part 220 are connected to each other by fasteners. The fasteners may include various types of screws, which can reliably connect the first fastening part 130 and the second fastening part 220.

[0039] In the above technical solution, by providing a plug-in portion 120 in the main housing 100 and a plug-in adapter portion 210 in the side plate 200, the side plate 200 can be installed into the mounting opening 110 via a plug-in connection. After the side plate 200 is installed, it can only be disassembled in the direction opposite to the first direction. This ensures that the side plate 200 is reliably installed onto the main housing 100 and will not loosen in the lateral direction. A small number of fasteners can limit the side plate 200, preventing it from accidentally moving and falling off in the direction opposite to the first direction. In summary, the combination of fasteners and plug-in portions ensures both ease of assembly and maintenance and a reliable connection between the side plate 200 and the main housing 100.

[0040] For example, the plug-in portion 120 may include a first plug-in portion 121. The first plug-in portion 121 extends from the edge of the mounting opening 110 beyond the main housing 100, and the plug-in adapter portion 210 includes a first plug-in adapter portion 211 that mates with the first plug-in portion 121. The side plate 200 includes a side plate body 230 and a flange 240, which bends and extends from the side plate body 230 toward the main housing 100 such that the flange 240 and the side plate body 230 enclose a corner space 250, and the first plug-in adapter portion 211 is disposed within the corner space 250.

[0041] Return to reference Figure 1 The corners of some parts of the housing assembly are rounded to reduce the possibility of bumps and injuries during handling, and also to improve the overall aesthetics. The side panels 200 can be fitted with flanges 240 along their height to form rounded corners. Figure 3A The structure of the first plug-in portion 121 is shown. The first plug-in portion 121 extending from the main housing 100 can cooperate with the first plug-in adapter portion 211, so that the first plug-in adapter portion 211 on the side plate 200 does not need to extend out of the flange 240, making the structure simpler.

[0042] like Figure 3AAs shown, exemplarily, the first insertion portion 121 may include a first reinforcing rib 1211, which is disposed on the inner surface of the main housing 100. The first reinforcing rib 1211 has a first protruding end 1211A, which extends beyond the main housing 100 via the edge of the mounting opening 110. The first reinforcing rib 1211 can be formed on the main housing 100 during injection molding, thereby improving the strength of the main housing 100. The first insertion portion 121 may also include an insertion portion 1212, which extends from the first protruding end 1211A along the insertion direction in which it interlocks with the first insertion adapter 211. Due to the high strength of the reinforcing rib, the formation of the first insertion portion 121 by the reinforcing rib ensures that the outer side plate 200 will not loosen even under large external forces. The surface of the insertion portion 1212 facing the main housing 100 can abut against the surface of the first insertion adapter 211, thereby limiting its position in the lateral direction.

[0043] Reference Figure 3A and Figure 3B For example, the first plug-in adapter 211 may include a frame 2111 connected to the flange 240 and the main housing 100, and the frame 2111 has an insertion port facing the insertion direction of interlocking with the first plug-in portion 121. The first plug-in adapter 211 may also include a guide vertex 2112 extending from the edge of the insertion port along the insertion direction. Figure 4 As shown, the frame 2111 is connected to both the flange 240 and the side panel body 230. When subjected to external force, it can distribute the force between the flange 240 and the side panel body 230, thus enabling it to withstand greater external forces. Simultaneously, the first insertion adapter 211 also acts as a reinforcing rib between the flange 240 and the side panel body 230, making the flange 240 less prone to deformation under external forces. Figure 4 and Figure 5The diagram shows schematic views of the first insertion part 121 and the first insertion adapter part 211 at different angles after they are engaged. The first insertion part 121 includes an insertion part 1212 protruding along the depth direction. As described above, during engagement, the side plate 200 can cover the mounting opening 110 in the lateral direction. By adjusting the position of the side plate 200, the insertion part 1212 can be accommodated in the guide gap between the guide eaves 2112 and the flange 240. At this time, the guide eaves 2112 can limit the side plate 200 in the height direction, which can be referred to as the pre-installation position. At this time, the side plate 200 can only move along the depth direction, except in the lateral direction. By pushing the side plate 200 along the depth direction, the insertion part 1212 can be inserted into the insertion port. The frame 2111 can limit the insertion part 1212. Only when the insertion part 1212 exits the insertion port in the depth direction can the side plate 200 be removed in the lateral direction. When the insertion part 1212 is inserted into the insertion port and in place, the guide eaves 2112 can also support the first protruding end 1211A.

[0044] Therefore, the frame 2111, which connects both the flange 240 and the side panel body 230, not only limits the first insertion portion 121 from the side but also improves the stability of the flange 240. The guide eaves 2112 prevent the side panel 200 from misaligning in the pre-installation position; in other words, when the side panel 200 is installed in the pre-installation position, it can only move along the first direction to be installed in place. When the side panel 200 is installed in place, the guide eaves 2112 can further limit and support the first protruding end 1211A.

[0045] For example, the mounting opening 110 includes a first edge 111 and a second edge 112 opposite to each other along a second direction, the second direction being perpendicular to the first direction and parallel to the plane containing the mounting opening 110; and a third edge 113 and a fourth edge 114 opposite to each other along the first direction, wherein: the insertion portion 120 includes a plurality of first insertion portions 121, the plurality of first insertion portions 121 being disposed on the first edge 111 and the second edge 112; and a first fastening portion 130 being disposed on the third edge 113. Thus, the side plate 200 and the main housing 100 have three fixing portions, and the three fixing portions are respectively located at the three edges of the side plate 200, thereby providing reliable fixing. Furthermore, the structure for fixing using the first insertion portions 121 and the first insertion adapter portion 210 is symmetrically arranged on both sides of the mounting opening 110, while the structure for fixing using fasteners is arranged on the other side, making the force on the side plate 200 more uniform in the symmetrical direction, while reducing the number of fasteners.

[0046] For example, the first edge 111 and the second edge 112 are the upper and lower edges of the mounting opening 110, respectively; and the third edge 113 and the fourth edge 114 are the rear and front edges of the mounting opening 110, respectively. As described above, the portion of the side plate 200 corresponding to the first edge 111 and the second edge 112 is provided with a rounded flange 240. A first fastening portion 130 is provided at the third edge 113, where the side plate 200 can be constructed as a plane. After the fastener is installed, the nuts and the like of the fastener will not protrude from the surface of the housing assembly.

[0047] Return to reference Figure 3A For example, the fourth edge 114 may be provided with a first stop 140 protruding from the mounting opening 110, and the side plate 200 abuts against the first stop 140 when it is mounted on the main housing 100. Figure 6 As shown, the insertion portion 120 includes a second insertion portion 122, which is disposed on the inner surface of the first retaining edge 140 facing the third edge 113. The second insertion portion 122 can cooperate with the first insertion portion 121 to limit the side panel 200 in at least the lateral direction after it has moved into place along the first direction. Thus, when the side panel 200 is installed in place, all four edges are fixed and limited towards the main housing 100, with almost no gaps. This makes it more suitable for the harsh environment of the under-sink, and it is less likely to accumulate dirt.

[0048] For example, a snap-fit ​​portion 141 may be provided on the inner surface of the first retaining edge 140, and a snap-fit ​​adapter portion 260 may be provided on the side plate 200. The snap-fit ​​portion 141 and the snap-fit ​​adapter portion 260 snap into each other along a first direction. The snap-fit ​​adapter portion 260 can provide a certain tactile feedback when the side plate 200 is installed in place, and generate a certain resistance when the side plate 200 moves away from the first direction, thereby giving the operator certain feedback so that the operator can confirm that the side plate 200 is correctly installed. At the same time, before the operator installs the fasteners, the snap-fit ​​portion 141 can prevent the side plate 200 from accidentally sliding and causing the first insertion portion 121 and the second insertion portion 122 to separate from their respective insertion adapter portions 210.

[0049] like Figure 7As shown, exemplarily, the snap-fit ​​portion 141 is provided with a snap-fit ​​groove, which has at least a snap-fit ​​opening facing the side plate 200. The snap-fit ​​adapter portion 260 includes a first sidewall 261 and a second sidewall 262. One side of both the first sidewall 261 and the second sidewall 262 is connected to the inner surface of the side plate 200, and the other side of the first sidewall 261 and the second sidewall 262 are spaced apart to form a gap. The gap extends along a first direction. The first sidewall 261, the second sidewall 262 and the inner surface of the side plate 200 together form an insertion cavity 264. The insertion portion 120 is inserted into the insertion cavity 264 along the first direction. The snap-fit ​​adapter portion 260 may also include a snap-fit ​​protrusion 265, which is connected to the inner surface of the side plate 200 within the insertion cavity 264. The snap-fit ​​protrusion 265 engages with the snap-fit ​​opening on the snap-fit ​​portion 141 within the insertion cavity 264 along the first direction. The aforementioned snap-fit ​​protrusion 265 provides a tactile feedback during the installation of the side plate 200. The protrusion 265 snaps into the snap-fit ​​opening, allowing the snap-fit ​​groove to elastically deform in the protruding direction of the protrusion 265. The gap between the first sidewall 261 and the second sidewall 262 reduces the rigidity of the snap-fit ​​adapter 260, thereby increasing the elastic deformation. During engagement, the first sidewall 261 and the second sidewall 262 also provide limits in the height and lateral directions to prevent misalignment between the protrusion 265 and the snap-fit ​​groove. After the protrusion 265 snaps into the snap-fit ​​groove, a certain resistance is generated when the side plate 200 moves in the opposite direction to the first direction, preventing the side plate 200 from accidentally falling off.

[0050] For example, the snap-fit ​​protrusion 265 has a first side and a second side opposite to each other along a first direction. A first guide slope 2651 and a second guide slope 2652 are respectively provided on the first side and the second side, wherein the first guide slope 2651 and the second guide slope 2652 are inclined towards each other and towards the interior of the main housing 100. Thus, the snap-fit ​​protrusion 265 forms a trapezoidal structure. During the installation of the side plate 200 from its pre-installation position along the first direction, the snap-fit ​​groove elastically deforms under the guidance of the first guide surface. After the side plate 200 is installed, during disassembly, the snap-fit ​​groove elastically deforms under the guidance of the second guide surface. Therefore, the resistance provided by the snap-fit ​​protrusion 265 is within a suitable range, ensuring that the side plate 200 can be easily disassembled and installed, while preventing it from slipping under its own weight or other external forces.

[0051] Reference Figure 2 and Figure 3BExemplarily, the first fastening portion 130 may include a second reinforcing rib 131 disposed on the inner surface of the main housing 100. The second reinforcing rib 131 has a second protruding end 1311 extending beyond the main housing 100 via a third edge 113 of the mounting opening 110. The first fastening portion 130 may also include a first fastening hole 132 disposed on the second reinforcing rib 131. Similar to the first reinforcing rib 1211, the second reinforcing rib 131 can be injection molded onto the main housing 100 and has high strength. Optionally, the first fastening hole 132 may be formed by a tapped hole in the second reinforcing rib 131. Optionally, the first fastening hole 132 may be formed by a nut embedded in the second reinforcing rib 131. In an embodiment not shown, the first fastening hole 132 may also be formed by a nut disposed on the surface of the second reinforcing rib 131 and a through hole in the second reinforcing rib 131. In summary, the thickness of the second reinforcing rib 131 allows it to be embedded in a nut or tapped, and it has sufficient strength.

[0052] Exemplarily, the side plate 200 includes a side plate body 230 and a second flange 270. The second flange 270 is disposed corresponding to the third edge 113 of the mounting opening 110, and the second flange 270 extends bently from the side plate body 230 toward the main housing 100. The second fastening portion 220 includes a second fastening hole 271 disposed on the second flange 270. The second flange 270 can abut against the second protruding end 1311, thereby cooperating with the first flange 140 to further limit the side plate 200 in the depth direction. At the same time, the second flange 270 can structurally improve the strength of the side plate 200. When the side plate 200 is installed in place, the second flange 270 can cover the second protruding end 1311, making the housing assembly look cleaner. The portion around the second fastening hole 271 disposed on the second flange 270 has sufficient strength to distribute the pressure of the fastener.
