Technical Field
[0001] This utility model relates to the field of metal casings, specifically to an electrical casing with reinforced edge structure. Background Technology
[0002] Most current electrical appliance metal casings use a uniform wall thickness design, making them prone to deformation and cracking during transportation or use. Existing technologies typically use external metal corner protectors to improve the local structural strength of the casing. However, adopting an overall thickening solution would significantly increase material costs and impact the product's lightweight requirements. While external corner protectors can provide localized reinforcement, they require additional assembly processes and may risk detachment over long-term use. Therefore, a solution is needed that can selectively strengthen the casing structure while maintaining the advantage of a thin-walled main body. Utility Model Content
[0003] The problem to be solved by this utility model is to provide an electrical appliance housing with a reinforced edge structure.
[0004] To solve the above problems, this utility model provides an electrical appliance housing with reinforced edge structure. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: An appliance housing reinforced with an edge structure includes: a front panel comprising a front shell plate, an inner shell plate, and a rear shell plate arranged parallel to each other; side panels vertically fixed to both sides of the front panel, the side panels being divided into a side perforation, a second side shell plate, and a first side shell plate from the center outwards, the thickness of the first side shell plate being greater than the thickness of the second side shell plate; a raised ridge line located on the side of the front shell plate facing away from the inner shell plate, the raised ridge line protruding along the edge of the front shell plate; and side strips, side strips extending in opposite directions vertically fixed to the facing surfaces of the two side panels, the side strips being located on the same side of all the front panels; wherein, the space enclosed by the front shell plate, the inner shell plate, and the two side panels is a front cavity, the front cavity being able to accommodate human-machine interface components; the space enclosed by the inner shell plate, the rear shell plate, and the two side panels is a rear cavity, the rear cavity being able to accommodate electrical control components; and the side strips being able to be assembled with fasteners.
[0005] As a further improvement of this utility model, the trajectory of the convex ridge line is a rounded rectangle when viewed from a perspective perpendicular to the front panel.
[0006] As a further improvement of this utility model, from a perspective perpendicular to the side panel, the side cutout, the second side shell plate, and the first side shell plate each have the same edge shape, and the thickness of the side panel increases in a stepped manner from the central area to the surrounding area.
[0007] As a further improvement of this utility model, the side panel has protruding corners extending from both ends in its length direction.
[0008] As a further improvement of this utility model, the vertical distance from the side strip to the rear shell is less than the vertical distance from the front shell to the inner shell, and the vertical distance from the front shell to the inner shell is less than the vertical distance from the inner shell to the rear shell.
[0009] As a further improvement of this utility model, the front shell plate, inner shell plate and rear shell plate are respectively provided with a first hollow hole, a second hollow hole and a third hollow hole, and the side strip plate is provided with a number of fixing holes for fasteners to pass through; the first hollow hole is used to expose the human-machine interaction component, and the second hollow hole is used for the wires between the human-machine interaction component and the electrical control component to pass through.
[0010] As a further improvement of this utility model, the reverse projection of the side strip plate along its own protrusion direction intersects with the first side shell plate, and the reverse projection of the convex ridge line along its own protrusion direction intersects with the second side shell plate.
[0011] As a further improvement of this utility model, one end of the front shell plate and the side facing away from the inner shell plate are provided with a thickened part, and the surface of the thickened part is recessed with several parallel groove lines.
[0012] As a further improvement of this utility model, the front panel, side panel, raised ridge line, and edge strip are made of aluminum or plastic material as a whole.
[0013] The advantages of using the edge-reinforced electrical housing technology of this application are: First, the side panels adopt a stepped thickening design from the center outwards, making the outermost first side shell plate thicker than the inner second side shell plate. This is equivalent to specifically strengthening the structural strength of the side panel edges, effectively resisting deformation and cracking. This is the first layer of edge structural reinforcement.
[0014] Secondly, a ring of raised ridges along the edge of the outer surface of the front shell forms a reinforcing ring, significantly improving the panel's resistance to bending and impact. This is the second layer of edge reinforcement.
[0015] Next, the two side panels are vertically connected by side strips extending in opposite directions, forming a lateral rigid support structure. These side strips also effectively strengthen the edge structure of the adjacent rear shell. This is the third layer of edge reinforcement.
[0016] Then, the front panel and side panels are firmly combined into a single frame, significantly enhancing the overall torsional resistance of the housing. The naturally separated front and rear cavities inside accommodate the human-machine interface components and electrical control components, respectively, optimizing the spatial layout to facilitate component installation and maintenance.
[0017] Finally, by locally thickening the edges and adding reinforcing structures such as raised ridges and edge strips in key areas, the traditional overall thickening or external corner protectors are replaced. This approach ensures structural strength while minimizing material usage, achieving both lightweight and cost advantages. The edge strips also provide direct assembly interfaces with fasteners, ensuring reliable installation and fixation of the housing. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, an electrical enclosure with reinforced edge structure includes: a front panel comprising a front shell plate 1, an inner shell plate 2, and a rear shell plate 3 arranged parallel to each other; side panels vertically fixed to both sides of the front panel, the side panels being divided into side perforations 7, a second side shell plate 6, and a first side shell plate 5 from the center outwards, the thickness of the first side shell plate 5 being greater than the thickness of the second side shell plate 6; a raised ridge 8 located on the front shell plate 1 and facing away from the inner shell plate 2, the raised ridge 8 protruding along the edge of the front shell plate 1; and side strip plates 4, which are vertically fixed to the facing surfaces of the two side panels, extending in opposite directions, the side strip plates 4 being located on the same side of all the front panels. The space enclosed by the front shell plate 1, the inner shell plate 2, and the two side panels is a front cavity 12, which can accommodate human-machine interface components. The space enclosed by the inner shell plate 2, the rear shell plate 3, and the two side panels is a rear cavity 13, which can accommodate electrical control components. The edge strip 4 can be assembled with fasteners.
[0022] The beneficial effects of adopting the above technical solution are as follows: the shell's stepped thickening from the center outwards through the side panels significantly enhances the edge's resistance to deformation; the annular ridge line 8 protruding from the outer edge of the front shell panel 1 effectively improves the panel's bending strength. The side strips 4 on both sides form a rigid lateral connection, integrating the front panel and side panels into a stable frame. The naturally separated front cavity 12 and rear cavity 13 optimize the component layout. The side strips 4 provide reliable assembly interfaces. Overall, while strengthening key parts, the amount of material used is controlled, balancing strength, lightweight, and cost.
[0023] In some other embodiments of this utility model, the trajectory of the convex ridge line 8 is a rounded rectangle when viewed from a perspective perpendicular to the front panel.
[0024] The beneficial effects of adopting the above technical solution are: the raised edge line 8 adopts a rounded rectangular trajectory, which can distribute stress more evenly compared with the sharp corner design, reduce the risk of stress concentration at the corners, and improve the impact resistance and fatigue resistance of the front shell plate 1 edge.
[0025] In some other embodiments of this utility model, from a perspective perpendicular to the side panel, the side cutout 7, the second side shell plate 6, and the first side shell plate 5 each have the same edge shape, and the thickness of the side panel increases in a stepped manner from the central area to the surrounding area.
[0026] like Figure 7 As shown, the outlines of the side hollow hole 7, the second side shell plate 6, and the first side shell plate 5 are all hexagonal in shape.
[0027] In addition, the thickness of the side perforation 7 is equivalent to zero, and the thickness of the first side shell plate 5 is twice the thickness of the second side shell plate 6.
[0028] The beneficial effects of adopting the above technical solution are: the thickness of the side panel increases in a stepwise manner from the central area to the surrounding area, and the side cutout 7, the second side shell plate 6, and the first side shell plate 5 have the same edge shape, forming a smooth transition thickness gradient, which is equivalent to using the offset command to generate the outline of the side cutout 7, the second side shell plate 6, and the first side shell plate 5 during design and drawing.
[0029] In some other embodiments of the present invention, the side panel extends at both ends of its length direction with protruding corner portions 11.
[0030] like Figure 7 As shown, the convex corner has 11 obtuse convex angles.
[0031] The beneficial effects of adopting the above technical solution are: the convex corners 11 extending at both ends of the side panel in the length direction provide additional support points and contact surfaces for the shell, enhance the pressure resistance of the shell ends, and play a role in positioning and anti-collision protection during assembly, avoiding misalignment during assembly.
[0032] In some other embodiments of this utility model, the vertical distance from the side strip plate 4 to the rear shell plate 3 is less than the vertical distance from the front shell plate 1 to the inner shell plate 2, and the vertical distance from the front shell plate 1 to the inner shell plate 2 is less than the vertical distance from the inner shell plate 2 to the rear shell plate 3.
[0033] The beneficial effects of adopting the above technical solution are: setting the distance between the side strip plate 4 and the rear shell plate 3 to be the shortest, the distance between the front shell plate 1 and the inner shell plate 2 to be in the middle, and the distance between the inner shell plate 2 and the rear shell plate 3 to be the largest. This depth difference allows the rear cavity 13 to have a larger capacity to accommodate the heat dissipation requirements of the electrical control components, while the front cavity 12 is more compact because the human-computer interaction components such as the display screen are relatively thin overall.
[0034] In some other embodiments of this utility model, the front shell plate 1, the inner shell plate 2, and the rear shell plate 3 are respectively provided with a through first hollow hole 101, a second hollow hole 201, and a third hollow hole 301, and the side strip plate 4 is provided with a plurality of fixing holes 401 through which fasteners can pass. The first hollow hole 101 is used to expose the human-machine interaction component, and the second hollow hole 201 is used for the wires between the human-machine interaction component and the electrical control component to pass through.
[0035] Furthermore, the opening area of the third perforation 301 is smaller than the opening areas of the first perforation 101 and the second perforation 201. For example... Figure 6 As shown, the third perforation 301 is used to contact the hook.
[0036] The height of the two side strips 4 is less than the width of the rear shell 3, and the space between the side strips 4 and the rear shell 3 can also be used as a slot.
[0037] The beneficial effects of adopting the above technical solution are as follows: the first cutout 101 of the front shell plate 1 ensures that the functions of the human-machine interaction components are exposed; the second cutout 201 of the inner shell plate 2 facilitates the connection of wires between the front and rear components; and the third cutout 301 of the rear shell plate 3 meets the external interface requirements. The fixing holes 401 of the side strip plate 4 provide fastener mounting points. Each hole performs its own function, improving the functionality of the shell and the ease of assembly.
[0038] like Figure 5 As shown, in some other embodiments of this utility model, the reverse projection of the side strip plate 4 along its own protrusion direction intersects with the first side shell plate 5, and the reverse projection of the convex ridge line 8 along its own protrusion direction intersects with the second side shell plate 6.
[0039] The beneficial effects of adopting the above technical solution are: the reverse projection of the side strip plate 4 in its own convex direction intersects with the first side shell plate 5, and the reverse projection of the convex ridge line 8 intersects with the second side shell plate 6, ensuring that the supporting force of the side strip plate 4 is effectively transmitted to the thickest area of the first side shell plate 5, while the reinforcing effect of the convex ridge line 8 covers the edge of the thinner second side shell plate 6, forming a continuous force transmission path.
[0040] like Figure 2 As shown, in some other embodiments of the present invention, one end of the front shell plate 1 and the side facing away from the inner shell plate 2 is provided with a thickened portion 9, and the surface of the thickened portion 9 is recessed with a plurality of parallel groove lines 10.
[0041] The groove line 10 is arranged obliquely, and the depth of the groove line 10 is less than the protrusion thickness of the thickened part 9.
[0042] The beneficial effects of adopting the above technical solution are: a thickened portion 9 with parallel groove lines 10 is provided on the outer surface of a specific end of the front shell plate 1, which greatly improves the impact resistance and wear resistance of that local area. The groove lines 10 also increase surface friction and improve the shape.
[0043] In some other embodiments of this utility model, the front panel, side panel, raised ridge line 8, and edge strip 4 are made of aluminum or plastic material as a whole.
[0044] The beneficial effects of adopting the above technical solution are: the front panel, side panel, raised ridge line 8, and edge strip 4 are made of one-piece molded aluminum or plastic, eliminating the structural weaknesses caused by the connection gaps, significantly improving the overall rigidity and structural integrity, and simplifying the manufacturing process.
[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
