[0026] The utility model provides a kind of box type piece with rib body, as shown in Figure 1 Box type piece with rib body, comprising: box body, including top and the side portion 2 being arranged along the circumference of top, the top is configured with multiple rib bodies 3;

[0027] Among them, the top 1 has the outer surface and inner surface arranged in the thickness direction thereof, and the rib body 3 is arranged in the recessed manner on the outer surface of the top, and is arranged in the protruded manner on the inner surface of the top 1.

[0028] The utility model provides a kind of box type piece with rib body, as shown in Figure 1 The specific structure includes: top 1 and the side portion 2 being arranged along the circumference of top 1, and the top 1 is configured with multiple rib bodies 3. The top 1 is a planar structure, and has an outer surface and an inner surface arranged in the thickness direction thereof. Among them, the rib body 3 forms a recessed structure on the outer surface of the top 1, and forms a corresponding protruded structure on the inner surface of the top 1. Specifically, each rib body 3 appears as a recessed groove structure on the outer surface of the top 1, and the depth direction of the recessed groove is consistent with the thickness direction of the top 1, i.e. extending from the outer surface to the inside; correspondingly, the recessed groove structure forms a ribbed structure protruding outward on the inner surface of the top 1, and the protrusion height matches the groove depth, so that the inner surface forms a reinforcing structure protruding into the box body at the corresponding position of the rib body 3.

[0029] In the present embodiment, asFigure 1 , Figure 2 and Figure 3 As shown, a plurality of ribs 3 are evenly distributed on the outer surface of the top 1. Each rib 3 is arranged at intervals along the length of the top 1. The outer surface of each rib 3 is concave to form an arc-shaped groove 31 that is recessed into the inner side of the top 1. The arc-shaped groove 31 is composed of multiple transition curved surfaces and outwardly convex arc surfaces that are smoothly connected to form an overall arc-shaped groove 31 structure that is recessed into the inner side of the top 1. Correspondingly, the inner surface of the top 1 forms an outwardly convex arch structure 32 in the projection area of ​​the arc-shaped groove 31. The height of the outward convexity matches the depth of the concavity on the outer surface.

[0030] The convex arc surface is located at the boundary edge between the arc-shaped groove 31 and the outer surface of the top 1, achieving a smooth connection with the outer surface of the top 1. Specifically, the convex arc surface connects the groove edge of the arc-shaped groove 31 with the ungrooved area of ​​the outer surface of the top 1, allowing the outer surface to transition smoothly at the groove edge. This enables external loads to be evenly transferred to the main structure of the arc-shaped groove 31 through the transition area at the groove edge. It also facilitates mold forming or machining, improving the feasibility of the manufacturing process and avoiding increased machining difficulty and mold wear caused by sharp edges.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the arc-shaped groove 31 exhibits a gradient distribution of width and depth along its extension direction. In terms of width, the two end regions of the arc-shaped groove 31 gradually narrow from wide to narrow along the extension direction of the rib 3; in terms of depth, the two end regions of the arc-shaped groove 31 gradually shallow from deep to shallow along the extension direction of the rib 3. Simultaneously, the width of the bottom of the arc-shaped groove 31 is smaller than the width of the slot at the top 1, and the bottom of the groove is connected to the groove wall by a circular arc surface. Correspondingly, the outwardly convex arched structure 32 on the inner surface of the top 1 presents a geometric shape that is completely symmetrical to the groove on the outer surface at the same position, and the height of the outward convexity of the arched structure 32 corresponds to the depth of the arc-shaped groove 31. The central area of ​​the arc-shaped groove 31, with equal width and depth, covers the main stress area of ​​the top 1, providing stable structural support for the core load-bearing area. The transition areas on both sides, which gradually narrow and shallow, connect with the edge of the top 1 and the side structure 2. The arc-shaped groove 31 can evenly distribute the external load through the gradually changing curved surface structure, effectively improving the bending resistance and structural stability of the top 1.

[0032] In some embodiments, such as Figure 1As shown, the side part 2 is enclosed by at least five side plates, each of which is vertically connected to the circumference of the top part 1 and extends downward, together forming a polygonal box structure. The connection between any two adjacent side plates forms an obtuse angle, that is, the angle is greater than 90° and less than 180°, so that the overall side part 2 presents a non-right-angle turning solid profile. The obtuse angle formed by the connection between the two adjacent side plates is also the draft angle of the box-shaped part. By increasing the draft angle of the side part 2, on the one hand, the sheet metal can be fully stretched during the forming process, increasing the rigidity and reducing the springback. On the other hand, it can also reduce the demolding resistance of the box-shaped part, effectively avoiding the deformation of the material caused by excessive friction during demolding.

[0033] In the present embodiment, as shown in Figure 1 The side plate includes a first side plate extending along the length direction of the top part 1 and a second side plate adjacent to the first side plate 21, wherein the extension direction of the first side plate 21 is strictly parallel to the length direction of the top part 1, and the second side plate 22 is connected to the first side plate 21 at an obtuse angle. The rib 3 on the outer surface of the top part 1 has a linear extension structure, and the extension axis is completely parallel to the extension axis of the first side plate 21, so that the rib 3 forms a regular arrangement of the reinforcing structure along the length direction of the top part 1. Specifically, the first side plate 21 serves as the main load-bearing edge of the side part 2, and its plane is parallel to the symmetry axis of the length direction of the top part 1, providing a direct vertical transmission path for the load of the top part 1; the second side plate 22 is connected to the first side plate 21 at a predetermined obtuse angle, together forming the polygonal profile of the side part 2. The extension direction of the rib 3 is parallel to the first side plate 21, that is, the length direction of each rib 3 is consistent with the length direction of the top part 1, and the axes of the ribs 3 are parallel to each other in space and perpendicular to the width direction of the top part 1. The concave structure formed by the rib 3 on the outer surface of the top part 1 cooperates with the first side plate 21. When the top part 1 is subjected to a load in the length direction, the reinforcing ribs formed by the convex outer surface of the rib 3 can directly transmit stress to the corresponding first side plate 21 through the axis direction parallel to the first side plate 21, thereby improving the anti-distortion ability of the box-shaped part under complex load environment.

[0034] In another embodiment, as shown in Figure 1 The outer circumference of the side part 2 is provided with an outwardly extending annular flange 4, which is continuously distributed along the edge of the top end or the bottom end of the side part 2, forming a planar flange structure surrounding the side part 2. The annular flange 4 and the main body of the side part 2 are connected through a rounded corner 5, that is, the connection area between the outer surface of the side part 2 and the annular flange 4 is smoothly connected by a circular arc surface or a curved surface. The annular flange 4 provides additional support for the side part 2, enhances the stability of the entire box-shaped part, and enables it to better withstand external pressure and impact force. At the same time, when the box-shaped part is assembled with other components, the annular flange 4 can be used as a connection interface to realize reliable connection through welding, riveting or bolt fixing, etc.

[0035] In summary, the application provides a box-shaped member with a rib body, which disperses the surface layer pressure through the concave structure of the top outer surface and enhances the bending stiffness of the top through the rib-shaped form of the convex structure of the inner surface; the transition curved surface with multi-section curvature gradually changes the curved surface radius to gradually disperse the concentrated load along the extension direction of the groove body, eliminating the stress concentration points that may be generated by the traditional linear type or single curvature rib body; the central region of the arc-shaped groove body is equal in width and depth, the two side end portions are gradually narrow and shallow, and the bottom width is less than the width of the slotted portion, so that the groove wall forms an inwardly inclined support angle; when the top is subjected to pressure, the load can be transmitted to the side portion through the inclined groove wall, thereby improving the overall bending stiffness of the arc-shaped groove body; by increasing the draft angle between the adjacent side plates on the side portion, the sheet metal is sufficiently stretched during the forming process, the rigidity is increased, the springback is reduced, and the friction during the demolding process is reduced.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
