Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to housing components and home appliances. Background Technology

[0002] Housing assemblies are typically composed of a front shell and a rear shell connected together. However, due to limitations in manufacturing processes, it is difficult to achieve perfect dimensional accuracy among the various housing components, resulting in certain manufacturing tolerances. This often leads to gaps at the connection points between the front and rear shells, which not only affects the overall aesthetics of the housing assembly but may also reduce its stability. Utility Model Content

[0003] In view of this, the present invention provides a housing assembly and a household appliance to solve the problem that gaps appear at the connection between the front and rear housings, which not only affect the overall aesthetics of the housing assembly, but may also lead to a decrease in the stability of the housing assembly.

[0005] First shell;

[0006] The second housing is connected to the first housing;

[0007] A retaining ring is provided at the connection between the first housing and the second housing, with one end of the retaining ring being engaged with the first housing and the other end being engaged with the second housing, for providing tension to the connection between the first housing and the second housing.

[0008] Beneficial effects: By engaging one end of the retaining ring with the first housing limit and the other end with the second housing limit, the retaining ring continuously applies a tension force that brings the first and second housings closer together. This effectively eliminates the gaps that may occur between the first and second housings due to manufacturing tolerances or assembly loosening, making the first and second housings more tightly and firmly joined at the connection point, less prone to relative displacement or loosening, improving the overall structural tightness and stability of the housing assembly, and enhancing the aesthetics of the housing assembly.

[0013] The second housing is fixedly connected to the two connecting plates at both ends along the first direction; the first direction is the extension direction of the panel, and the second direction is perpendicular to the plane where the panel is located.

[0014] Beneficial effects: By setting the panel as the main load-bearing surface of the first housing and extending the panel along the first direction, while making the two side plates extend perpendicular to the panel, the rigidity and bending resistance of the first housing in the direction perpendicular to the panel are enhanced. Connecting plates are fixed to the ends of the two side plates and extend parallel to the panel. The two ends of the second housing along the first direction are fixedly connected to these two connecting plates, providing a flat fixing area for the connection between the second and first housings. This ensures that, under the action of the fixing ring, the second housing and the connecting plates can approach each other at the connection point, helping to eliminate the gap at the connection between the first and second housings and improving the reliability of the connection.

[0027] Beneficial effects: Since the second housing has an inwardly extending second folded edge along the second direction, the structural rigidity and deformation resistance of the edge of the second housing are enhanced; and the fixing ring is limited and engaged with the second folded edge, which avoids opening holes in the main body of the second housing, which helps to maintain the structural integrity of the main body of the second housing, reduces the structural strength loss caused by opening holes, and at the same time makes the appearance of the second housing simpler, avoiding the aesthetic problems caused by exposed parts.

[0028] In one alternative implementation, the second folded edge includes:

[0034] In one alternative embodiment, the end of the connecting plate opposite to the side plate is provided with an extended third folded edge; the snap-fit ​​structure is disposed on the third folded edge.

[0035] Beneficial effects: By setting an extended third folded edge, the structural rigidity and deformation resistance of the connecting plate end can be enhanced, reducing the deformation of the connecting plate under stress, making the overall structure of the connecting plate more stable, and thus improving the load-bearing capacity of the connection part with the second shell; and the snap-fit ​​structure is set on the third folded edge, avoiding the need to open holes in the main body of the connecting plate, which helps to maintain the structural integrity of the main body of the connecting plate, reduces the structural strength loss caused by opening holes, and at the same time makes the appearance of the connecting plate simpler, avoiding the aesthetic problems caused by exposed parts.

The second fold extends along the first direction, and the second shell also extends along the first direction, making the second fold parallel to the second shell. By setting the snap-fit ​​structure on the second fold, the fitting gap between the second shell and the second fold can be reduced, making the connection between the second shell and the second fold tighter and improving the strength and reliability of the connection. Furthermore, the structure formed by the continuous bending of the first and second folds can be formed in one step by sheet metal stamping and bending process, exhibiting good manufacturability.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0065] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0066] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0067] For products such as electric heaters, their high-power heating characteristics place higher demands on the materials of the exterior parts, so sheet metal materials are often used; however, sheet metal materials have the characteristics of springback deformation and dimensional instability after molding and processing, making it more difficult to control the fit gaps and step differences of the exterior parts after the electric heater is assembled into a whole machine.

[0068] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0069] According to embodiments of the present invention, on the one hand, such as Figures 1 to 3 As shown, a housing assembly is provided, including a first housing 10, a second housing 20, and a retaining ring 30; the second housing 20 is connected to the first housing 10; the retaining ring 30 is disposed at the connection between the first housing 10 and the second housing 20, and one end of the retaining ring 30 is engaged with the first housing 10 for limiting and locking, and the other end is engaged with the second housing 20 for limiting and locking, for providing tension force at the connection between the first housing 10 and the second housing 20.

[0070] In the above embodiment, one end of the retaining ring 30 is engaged with the first housing 10 and the other end is engaged with the second housing 20, so that the retaining ring 30 continuously applies a tension force to the first housing 10 and the second housing 20 to bring them closer together. This effectively eliminates the gaps that may occur between the first housing 10 and the second housing 20 due to manufacturing tolerances or loose assembly, making the first housing 10 and the second housing 20 more tightly and firmly connected at the joint, less prone to relative displacement or loosening, improving the overall structural tightness and stability of the housing assembly, and also improving the aesthetics of the housing assembly.

[0071] Specifically, the first housing 10 is provided with a first limiting hole 11, and one end of the fixing ring is provided with a first limiting protrusion 31, and the first limiting hole 11 and the first limiting protrusion 31 are engaged; or the first housing 10 is provided with a first limiting protrusion 31, and one end of the fixing ring is provided with a first limiting hole 11, and the first limiting hole 11 and the first limiting protrusion 31 are engaged.

[0072] Specifically, the second housing 20 is provided with a second limiting hole 21, and the other end of the fixing ring is provided with a second limiting protrusion 32, and the second limiting hole 21 and the second limiting protrusion 32 are engaged; or the second housing 20 is provided with a second limiting protrusion 32, and the other end of the fixing ring is provided with a second limiting hole 21, and the second limiting hole 21 and the second limiting protrusion 32 are engaged.

[0073] Specifically, both the first limiting hole 11 and the second limiting hole 21 are square holes. Compared with other shapes such as round holes, square holes can make contact with the plane of the first limiting protrusion 31 and the second limiting protrusion 32 through the hole wall, providing a more stable limiting effect and ensuring the stable transmission of tension force.

[0074] Specifically, after bending, the two ends of the retaining ring 30 are respectively formed into a first limiting protrusion 31 and a second limiting protrusion 32 that are adapted to the first limiting hole 11 and the second limiting hole 21. In the assembled state, the first limiting protrusion 31 is embedded in the first limiting hole 11 and abuts tightly against the hole wall of the first limiting hole 11, and the second limiting protrusion 32 is embedded in the second limiting hole 21 and abuts tightly against the hole wall of the second limiting hole 21. Through the constraint effect of the hole wall on the first limiting protrusion 31 and the second limiting protrusion 32, a reliable force support point is provided for the transmission of the tension force provided by the retaining ring 30 at the connection between the first housing 10 and the second housing 20.

[0075] Preferably, the retaining ring 30 can be made of a material with certain elasticity and strength, such as aluminum alloy, stainless steel, or high-strength engineering plastics such as nylon. When the first limiting protrusion 31 is engaged in the first limiting hole 11 and the second limiting protrusion 32 is engaged in the second limiting hole 21, the retaining ring 30 will undergo elastic deformation due to its own elastic properties. This elastic deformation causes the retaining ring 30 to continuously exert a force on the first housing 10 and the second housing 20 to move closer to each other, thereby ensuring the elimination of gaps between the first housing 10 and the second housing 20 caused by manufacturing tolerances or assembly loosening.

[0076] In some embodiments, the ends of the first limiting protrusion 31 and the second limiting protrusion 32 can be designed as barbed structures, so that after the engagement, the first limiting protrusion 31 and the second limiting protrusion 32 are not easy to come out of the first limiting hole 11 and the second limiting hole 21, further enhancing the engagement stability between the fixing ring 30 and the first housing 10 and the second housing 20.

[0077] In one embodiment, such as Figure 4 As shown, the first housing 10 includes a panel 12, two side plates 13, and two connecting plates 14; the panel 12 extends along a first direction and is disposed opposite to the second housing 20 along a second direction; the two side plates 13 are respectively connected to the two ends of the panel 12 along the first direction, and the side plates 13 extend along the second direction; the two connecting plates 14 are respectively connected to the side of the two side plates 13 away from the panel 12, and the connecting plates 14 extend along the first direction; wherein, the two ends of the second housing 20 along the first direction are respectively fixedly connected to the two connecting plates 14; the first direction is the extension direction of the panel 12, and the second direction is perpendicular to the plane where the panel 12 is located.

[0078] In the above embodiment, by setting the panel 12 as the main bearing surface of the first housing 10 and extending the panel 12 along the first direction, while making the two side plates 13 extend perpendicular to the panel 12, the rigidity and bending resistance of the first housing 10 in the direction perpendicular to the panel 12 are enhanced. The connecting plates 14 are respectively fixed to the ends of the two side plates 13 and extend parallel to the panel 12. The two ends of the second housing 20 along the first direction are respectively fixedly connected to the two connecting plates 14, providing a flat fixing area for the connection between the second housing 20 and the first housing 10. This ensures that under the action of the fixing ring 30, the second housing 20 and the connecting plates 14 can approach each other at the connection point, which helps to eliminate the gap at the connection point of the first housing 10 and the second housing 20 and improves the reliability of the connection.

[0079] In one embodiment, the first housing 10 is provided with an inwardly extending first folded edge 15; the retaining ring 30 is engaged with the first folded edge 15 for limiting.

[0080] In the above embodiments, since the first housing 10 is provided with an inwardly extending first folded edge 15, the structural rigidity and deformation resistance of the edge of the first housing 10 are enhanced; and the fixing ring 30 is limited and engaged with the first folded edge 15, which avoids opening holes in the main body of the first housing 10, which helps to maintain the structural integrity of the main body of the first housing 10, reduces the structural strength loss caused by opening holes, and also makes the appearance of the first housing 10 simpler, avoiding the aesthetic problems caused by exposed parts.

[0081] Specifically, "extending inward" refers to extending towards the interior of the housing assembly.

[0082] In one embodiment, the first folded edge 15 includes a first overlapping edge 151 and a first flange 152; the first overlapping edge 151 is formed by extending from the end of the first housing 10 along a third direction; the third direction is perpendicular to the first direction and the second direction; the first flange 152 is formed by extending inward from the first overlapping edge 151; the fixing ring 30 is engaged with the first flange 152 for limiting.

[0083] In the above embodiment, by first forming a first overlapping edge 151 along a third direction at the end of the first housing 10, and then extending inward to form a first flange 152, a double structure is formed by bending, which can enhance the overall rigidity and deformation resistance of the end of the first housing 10; and the first flange 152 extends along the second direction, providing an independent and flat mounting surface for the fixing ring 30, ensuring the positioning accuracy when the fixing ring 30 and the first flange 152 are engaged, and ensuring the stability of the connection between the two, making the overall structure more compact; and the structure formed by the continuous bending of the first overlapping edge 151 and the first flange 152 can be formed in one step by sheet metal stamping and bending process, which has good manufacturability.

[0084] Specifically, the first flange 152 is formed by extending the first overlapping edge 151 inward along a first direction; and / or, the first flange 152 is formed by extending the first overlapping edge 151 inward along a second direction.

[0085] In a specific implementation, the first overlapping edge 151 starts from one end of a connecting plate 14 connected to the second housing 20 and extends continuously along the end of the first housing 10 in the third direction until it reaches the end of another connecting plate 14 connected to the second housing 20. Through the through-extension design, the first overlapping edge 151 can completely cover the entire end area of ​​the first housing 10 in the third direction, forming a continuous and closed reinforced structure, which improves the structural stiffness and deformation resistance of the entire end of the first housing 10 in the third direction.

[0086] In one embodiment, such as Figure 8 As shown, the fixing ring 30 includes a fixing segment 33, a first connecting segment 34, and a second connecting segment 35; the fixing segment 33 is fixedly connected to the first flange 152; the first connecting segment 34 is connected to one end of the fixing segment 33, and the end of the first connecting segment 34 facing away from the fixing segment 33 is engaged with the first housing 10; the second connecting segment 35 is connected to the other end of the fixing segment 33; the second connecting segment 35 is provided along the protrusion of the connecting plate 14, and the protruding end is engaged with the second housing 20.

[0087] In the above embodiment, the fixed section 33 and the first flange 152 are fixedly connected to ensure a stable connection between the fixed ring 30 and the first housing 10; and the second connecting section 35 protrudes from the connecting plate 14, and the protruding end is engaged with the second housing 20 to provide a continuous clamping force at the connection between the first housing 10 and the second housing 20, thereby ensuring the elimination of the assembly gap at the connection between the first housing 10 and the second housing 20.

[0088] Specifically, such as Figure 2 and Figure 3As shown, the first flange 152 includes a first support section 1521, a second support section 1522, and a third support section 1523. The first support section 1521 corresponds to the position of the panel 12, and a first limiting hole 11 is provided on the first support section 1521. When the first limiting protrusion 31 engages with the first limiting hole 11, the first support section 1521 can provide stable support for the first connecting section 34, ensuring the reliability of the engagement. The first support section 1521 and the first connecting section 34 are fixed together by screws or other fasteners. The second support section 1522 corresponds to the position of the side plate 13, and the fixing section 33 is fixed together with the second support section 1522 by screws or other fasteners. The third support section 1523 corresponds to the position of the connecting plate 14, and the second connecting section 35 is fixed together with the third support section 1523 by screws or other fasteners. Specifically, in actual assembly, the screw holes 16 on the first support section 1521, the first connecting section 34, the fixing section 33, the second support section 1522, the second connecting section 35, and the third support section 1523 can all be designed as through holes. In this case, other components can be installed inside the housing assembly. By connecting the screws to these components, the first support section 1521 and the first connecting section 34 can be fastened, or the fixing section 33 and the second support section 1522 can be fastened, or the second connecting section 35 and the third support section 1523 can be fastened. This way, the fastening force is transmitted to the overall structure, which not only meets the connection requirements but also reserves connection positions for the installation of other components.

[0089] Specifically, during the assembly process, the first limiting protrusion 31 is engaged with the first limiting hole 11, the second limiting protrusion 32 is engaged with the second limiting hole 21, and then the first support section 1521 and the first connecting section 34, the fixed section 33 and the second support section 1522, and the second connecting section 35 and the third support section 1523 are fastened together by screws and other fasteners, thereby completing the assembly of the fixing ring 30 with the first housing 10 and the second housing 20.

[0090] In one embodiment, such as Figure 6 As shown, the second housing 20 is provided with an inwardly extending second folded edge 22; the fixing ring 30 is engaged with the second folded edge 22 for limiting.

[0091] In the above embodiment, since the second housing 20 is provided with an inwardly extending second folded edge 22 along the second direction, the structural rigidity and deformation resistance of the edge of the second housing 20 are enhanced; and the fixing ring 30 is limited and engaged with the second folded edge 22, which avoids opening holes in the main body of the second housing 20, which helps to maintain the structural integrity of the main body of the second housing 20, reduces the structural strength loss caused by opening holes, and at the same time makes the appearance of the second housing 20 simpler, avoiding the aesthetic problems caused by exposed parts.

[0092] In one embodiment, the second folded edge 22 includes a second overlapping edge 221 and a second folded edge 222; the second overlapping edge 221 is formed by extending from the end of the second housing 20 along a third direction; the second folded edge 222 is formed by extending from the second overlapping edge 221 along a second direction; and the retaining ring 30 is engaged with the second folded edge 222 for limiting.

[0093] In the above embodiment, by first forming a second overlapping edge 221 along a third direction at the end of the second housing 20, and then extending it along a second direction to form a second flange 222, a double structure is formed by bending, which can enhance the overall rigidity and deformation resistance of the end of the second housing 20; and the second flange 222 extends along the second direction, providing an independent and flat mounting surface for the fixing ring 30, ensuring the positioning accuracy when the fixing ring 30 and the second flange 222 are engaged, and ensuring the stability of the connection between the two, making the overall structure more compact; and the structure formed by the continuous bending of the second overlapping edge 221 and the second flange 222 can be formed in one step by sheet metal stamping and bending process, which has good manufacturability.

[0094] In a specific implementation, the length of the second overlapping edge 221 is consistent with the length of the extension direction of the second housing 20. Through the through-type extension design, it forms a complete coverage of the entire end area of ​​the second housing 20 in the third direction, forming a continuous and closed reinforced structure, which improves the structural stiffness and deformation resistance of the second housing 20 in the entire end area in the third direction.

[0095] In this embodiment, two second flanges 222 are respectively provided at the left and right ends of the second housing 20. These two second flanges 222 are respectively engaged with two fixing rings 30 at the left and right ends. In another embodiment, the length of the second flange 222 may be consistent with the length of the second housing 20 along its own extension direction, so that second limiting holes 21 can be formed at its left and right ends respectively, so that the second limiting protrusion 32 of each fixing ring 30 can be tightly engaged with the corresponding second limiting hole 21. Moreover, the second flange 222 along its entire length can also provide a stable connection structure for other components inside the housing assembly. When the components or parts inside the housing assembly are installed, they can be positioned and fixed by cooperating with the second flange 222.

[0096] Specifically, such as Figure 2As shown, the fixing ring 30 can be flexibly arranged at different positions on the housing assembly. For example, it can be simultaneously set at the upper and lower right end and the upper and lower left end of the housing assembly, achieving all-round fastening of the first housing 10 and the second housing 20 through multi-position fixing; or, depending on the force requirements and structural characteristics of the housing assembly, it can be set only at a single or partial position such as the upper right end, lower right end, upper left end, or lower left end. The setting of the first flange 152 and the second flange 222 can also be adaptively adjusted according to the fixing position of the fixing ring 30 to adapt to different usage scenarios, simplifying the structure and reducing costs while ensuring connection reliability.

[0097] In one embodiment, the connecting plate 14 is connected to the second housing 20 by a snap-fit ​​structure, the snap-fit ​​structure including a connecting hole 141 and a buckle 23 that cooperate with each other.

[0098] Specifically, the connecting plate 14 is provided with a connecting hole 141, and the second housing 20 is provided with a buckle 23, which engages with the connecting hole 141. Alternatively, the connecting plate 14 is provided with a buckle 23, and the second housing 20 is provided with a connecting hole 141, which engages with the connecting hole 141.

[0099] In the above embodiment, the connection between the second housing 20 and the connecting plate 14 is achieved by the snap-fit ​​of the buckle 23 and the connecting hole 141. No additional fasteners are required, which simplifies the assembly process, improves installation efficiency, facilitates subsequent disassembly and maintenance operations, and reduces the labor and time costs in the disassembly and assembly process.

[0100] In a specific embodiment, the connecting hole 141 is an elongated hole extending along a third direction, providing operating space for the insertion and engagement of the buckle 23. During assembly, the buckle 23 on the second housing 20 is aligned with the elongated hole on the connecting plate 14, and the buckle 23 is inserted into the elongated hole in a direction perpendicular to the surface of the connecting plate 14. At this time, the buckle 23 is in the initial position of the elongated hole and has not yet formed a complete engagement. Subsequently, the second housing 20 is slid downward along a third direction, so that the buckle 23 slides down synchronously in the elongated hole to a position corresponding to the length of the protruding part of the buckle 23. When the buckle 23 slides into place, its protruding part will form a mechanical engagement with the edge of the elongated hole, that is, the protruding structure of the buckle 23 abuts against the inner wall of the elongated hole, thereby achieving a stable assembly of the second housing 20 and the first housing 10.

[0101] In one embodiment, the end of the connecting plate 14 facing away from the side plate 13 is provided with an inwardly extending third folded edge 142; a snap-fit ​​structure is provided on the third folded edge 142.

[0102] In the above embodiment, by providing an inwardly extending third folded edge 142, the structural rigidity and deformation resistance of the end of the connecting plate 14 can be enhanced, the deformation of the connecting plate 14 under stress can be reduced, the overall structure of the connecting plate 14 can be made more stable, and the load-bearing capacity of the connection part with the second housing 20 can be improved. Furthermore, the snap-fit ​​structure is provided on the third folded edge 142, which avoids opening holes in the main body of the connecting plate 14, which helps to maintain the structural integrity of the main body of the connecting plate 14, reduces the structural strength loss caused by opening holes, and at the same time makes the appearance of the connecting plate 14 simpler, avoiding the aesthetic problems caused by exposed parts.

[0103] Specifically, the panel 12, two side panels 13, two connecting plates 14, first folded edge 15, and third folded edge 142 of the first housing 10 are manufactured using a sheet metal integral molding process. This is achieved through continuous stamping, bending, and other processing steps on a single sheet metal raw material, eliminating the need to manufacture each component separately and then assemble them through welding, riveting, or other methods. This forms a complete and continuous integral structure, which not only improves the structural strength and sealing performance of the first housing 10 but also facilitates mass production, increases production efficiency, and reduces manufacturing costs.

[0104] In one embodiment, the third folded edge 142 includes a first folded edge 1421 and a second folded edge 1422; the first folded edge 1421 is formed by extending the end of the connecting plate 14 along a second direction; the second folded edge 1422 is formed by extending the first folded edge 1421 along a first direction; and a snap-fit ​​structure is provided on the second folded edge 1422.

[0105] In the above embodiment, by setting a double-bending structure of the first folded edge 1421 and the second folded edge 1422, the overall structural strength and torsional resistance of the third folded edge 142 are enhanced, ensuring the support and reinforcement effect on the end of the connecting plate 14. The second folded edge 1422 extends along the first direction, and the second housing 20 also extends along the first direction, making the second folded edge 1422 parallel to the second housing 20. By setting the snap-fit ​​structure on the second folded edge 1422, the fitting gap between the second housing 20 and the second folded edge 1422 can be reduced, making the connection between the second housing 20 and the second folded edge 1422 tighter and improving the firmness and reliability of the connection. Furthermore, the structure formed by the continuous bending of the first folded edge 1421 and the second folded edge 1422 can be formed in one step by sheet metal stamping and bending process, which has good manufacturability.

[0106] In one embodiment, the second housing 20 has an inwardly extending fourth folded edge 24 at the end near the connecting plate 14; a snap-fit ​​structure is provided on the fourth folded edge 24.

[0107] In the above embodiment, by providing an inwardly extending fourth folded edge 24, the structural rigidity and deformation resistance of the end of the second housing 20 can be enhanced, the deformation of the second housing 20 under stress can be reduced, the overall structure of the second housing 20 can be made more stable, and the load-bearing capacity of the connection part with the connecting plate 14 can be improved; and the fourth folded edge 24 extends into the housing assembly, avoiding the snap-fit ​​structure from occupying the external space of the housing assembly, making the appearance of the second housing 20 simpler, and avoiding the aesthetic problems caused by exposed parts.

[0108] Specifically, the second housing 20, the second folded edge 22, and the fourth folded edge 24 are made using a sheet metal integral molding process.

[0109] In one embodiment, the fourth folded edge 24 includes a third folded edge 241 and a fourth folded edge 242; the third folded edge 241 is formed by extending from the end of the second housing 20 along a first direction; the fourth folded edge 242 is formed by extending from the end of the third folded edge 241 along a second direction; and a snap-fit ​​structure is provided on the fourth folded edge 242.

[0110] In the above embodiment, by setting a double-bending structure of the third fold 241 and the fourth fold 242, the overall structural strength and torsional resistance of the fourth fold 24 are enhanced, ensuring the support and reinforcement effect on the end of the second housing 20. The fourth fold 242 bends and extends along the second direction, making the fourth fold 242 perpendicular to the second fold 1422. Since the snap-fit ​​structure is set on the fourth fold 242, it helps to snap with the second fold 1422. Furthermore, the structure formed by the continuous bending of the third fold 241 and the fourth fold 242 can be formed in one step by sheet metal stamping and bending process, which has good manufacturability.

[0111] In one embodiment, the first end of the side panel 13 is smoothly connected to the panel 12 via a first arcuate portion 131; the second end of the side panel 13 is smoothly connected to the connecting plate 14 via a second arcuate portion 132.

[0112] In the above embodiments, the first arc-shaped portion 131 ensures a smooth transition connection between the first end of the side plate 13 and the panel 12; the second arc-shaped portion 132 ensures a smooth transition connection between the second end of the side plate 13 and the connecting plate 14, eliminating sharp edges that may exist in right-angle connections and reducing the risk of scratches caused by collisions and friction during assembly or daily use; and the first arc-shaped portion 131 and the second arc-shaped portion 132 make the connection between the side plate 13, the panel 12 and the connecting plate 14 more coordinated, improving the overall aesthetics of the housing assembly.
