Description

Technical Field

[0001] This application relates to the field of vehicle frame structure technology, and in particular to a reinforcing rib structure for a vehicle frame, a vehicle frame, and a vehicle. Background Technology

[0002] Existing vehicle frame structures are typically manufactured using die casting. To increase strength and rigidity, frame structures are usually reinforced by increasing the thickness of frame components. However, a thicker frame increases weight and is not conducive to reducing energy consumption and costs. Furthermore, the current reinforcement structures are limited in their variety, resulting in limited improvements in frame structural strength. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a reinforcing rib structure for a vehicle frame, which, through improvements to the reinforcing rib structure, can effectively enhance structural strength.

[0004] This application also proposes a vehicle frame having the above-mentioned reinforcing rib structure.

[0005] This application also proposes a vehicle having the aforementioned frame.

[0006] A reinforcing rib structure for a vehicle frame according to one embodiment of this application includes: a main structure, the main structure including a main base plate, a first side plate and a second side plate, the first side plate and the second side plate being spaced apart from the outside to the inside on the main base plate, and a plurality of polygonal cells being formed between the first side plate and the second side plate; a reinforcing component including a first reinforcing structure and a second reinforcing structure, at least one of the polygonal cells being provided with the first reinforcing structure or the second reinforcing structure; wherein, the first reinforcing structure includes intersecting first reinforcing ribs, one end of one of the first reinforcing ribs being a first connecting end, the first connecting end overlapping the second side plate and located in the middle of the polygonal cell; the second reinforcing structure includes intersecting second reinforcing ribs, the ends of the second reinforcing ribs being connected to the diagonals of the polygonal cell; the second reinforcing structure includes a second reinforcing post, the second reinforcing post being located at the intersection of two intersecting second reinforcing ribs.

[0007] Furthermore, the first connecting end is connected to the midpoint of the second side plate corresponding to the polygonal cell.

[0008] Furthermore, the second reinforcing column has a slot extending along its length.

[0009] Furthermore, the second reinforcing rib is connected to one side of the first side plate as the second connecting side, and the height of the second reinforcing rib gradually increases from the second side plate to the first side plate.

[0010] Furthermore, the outline of the second reinforcing rib on the side away from the main substrate is arc-shaped.

[0011] Furthermore, the main structure also includes a plurality of connecting plates, which are spaced apart between the first side plate and the second side plate, and the plurality of connecting plates, the first side plate and the second side plate define a plurality of polygonal cells.

[0012] Furthermore, the height of the first side plate is greater than the height of the second side plate.

[0013] In another embodiment of this application, the vehicle frame includes a reinforcing rib structure as described above for the vehicle frame. Two of the reinforcing rib structures are symmetrically arranged to form the main body of the vehicle frame. The vehicle frame also includes a connecting structure, which is mounted on the second side plate and is used for connection with the outside.

[0014] Furthermore, the main substrate includes a first part and a second part arranged horizontally, the first part and the second part being in the form of a broken line, the orientation of the second side plate in the height direction matching that of the main substrate, and the connecting structure being disposed at the position of the second side plate corresponding to the first part.

[0015] The vehicle of another embodiment of this application has the frame as described above.

[0016] The reinforcing rib structure, frame, and vehicle according to the embodiments of this application have at least the following beneficial effects: In the embodiments of this application, by setting polygonal cells on the main structure and setting a first reinforcing structure or a second reinforcing structure within the polygonal cells, the structural strength of the frame is effectively improved. Specifically, one end of one of the first reinforcing ribs of the first reinforcing structure is connected to the diagonal of the polygonal cell, and the other end, i.e., the first connecting end, overlaps the middle of the polygonal cell, which helps to improve the structural strength of the polygonal cell and effectively reduces the bending or concave deformation of the polygonal cell's sides, thus improving the structural strength of the frame. The first connecting end of the first reinforcing rib overlaps the middle of the second side plate corresponding to the polygonal cell, which helps to evenly distribute the force on the second side plate, thereby improving the load-bearing capacity of the second side plate, i.e., improving the structural strength of the reinforcing rib structure. Since the two first reinforcing ribs of the first reinforcing structure are not symmetrically arranged... Placing it within a polygonal cell improves the stability of the polygonal cell, thereby further enhancing the structural strength of the reinforcing rib structure. When one end of the first reinforcing rib is connected to the opposite corner of the polygonal cell and the other end overlaps the middle of the side, it helps to shorten the length of the first reinforcing rib and improve its strength, thus enhancing the overall strength of the reinforcing rib structure. The second reinforcing structure includes second reinforcing ribs with their ends connected to the opposite corner of the polygonal cell, and second reinforcing columns are provided at the positions of the two intersecting second reinforcing ribs, which helps to improve the structural strength of the polygonal cell and thus enhance the structural strength of the reinforcing rib structure.

[0017] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] One embodiment of this application discloses a reinforcing rib structure for a vehicle frame, such as... Figures 1 to 4 As shown, the reinforcing rib structure includes a main structure and reinforcing components.

[0032] Specifically, such as Figures 1 to 4 As shown, the main structure includes a main substrate 110, a first side plate 120, and a second side plate 130. The first side plate 120 and the second side plate 130 are spaced apart from the outside to the inside on the main substrate 110, and a plurality of polygonal cells 140 are formed between the first side plate 120 and the second side plate 130. The first side plate 120 and the second side plate 130 constitute the sides of the polygonal cells 140 at corresponding positions.

[0033] It should be understood that the aforementioned "from the inside out" is relative to the virtual cutting line AA of the frame. For example, in this embodiment, the second side plate 130 is closer to the cutting line AA than the first side plate 120, so the first side plate 120 is located on the inside and the second side plate 130 is located on the outside.

[0034] See Figure 4 The reinforcing components include a first reinforcing structure 210 and a second reinforcing structure 220, with at least one polygonal cell 140 containing either the first reinforcing structure 210 or the second reinforcing structure 220. The first reinforcing structure 210 includes intersecting first reinforcing ribs 211, one end of which is a first connecting end 2111, overlapping the second side plate 130 and located in the middle of the polygonal cell 140. The second reinforcing structure 220 includes intersecting second reinforcing ribs 221, the ends of which are connected to opposite corners of the polygonal cell 140. Specifically, each first reinforcing structure 210 includes two first reinforcing ribs 211, one end of which is connected to opposite corners of the polygonal cell 140, and the other end, the first connecting end 2111, overlaps the middle of the second side plate 130 corresponding to the polygonal cell 140. It should be understood that the second side plate 130 corresponding to each polygon cell 140 constitutes the side of the polygon cell 140, and the first connecting end 2111 overlaps the middle of the side; the "middle" refers to the position between the two ends of the side of the polygon cell 140.

[0035] It should be understood that each polygon cell 140 with the first reinforcing structure 210 has a first connecting end 2111.

[0036] In the embodiments of this application, the structural strength of the reinforcing rib structure is effectively improved by forming polygonal cells 140 on the main structure of the reinforcing rib structure and setting a first reinforcing structure 210 or a second reinforcing structure 220 in the polygonal cells 140.

[0037] In this structure, one end of the first reinforcing rib 211 of the first reinforcing structure 210 is connected to the diagonal of the polygonal cell 140, and the other end, namely the first connecting end 2111, overlaps with the middle of the polygonal cell 140. This improves the structural strength of the polygonal cell 140 and effectively reduces the possibility of bending or denting deformation on the sides of the polygonal cell 140. The first connecting end 2111 of the first reinforcing rib 211 overlaps with the middle of the second side plate 130 corresponding to the polygonal cell 140, which helps to distribute the stress evenly on the second side plate 130, thereby improving the load-bearing capacity of the second side plate 130. Since the two first reinforcing ribs 211 of the first reinforcing structure 210 are not symmetrically arranged within the polygonal cell 140, the stability of the polygonal cell 140 can be improved, thereby further improving the structural strength of the reinforcing rib structure. When one end of the first reinforcing rib 211 is connected to the diagonal of the polygonal cell 140 and the other end overlaps the middle of the side, it is beneficial to shorten the length of the first reinforcing rib 211, thereby improving the strength of the first reinforcing rib 211, and thus improving the overall strength of the reinforcing rib structure. The second reinforcing structure 220 includes second reinforcing ribs 221 whose ends are connected to the diagonal of the polygonal cell 140, which is beneficial to improving the structural strength of the polygonal cell 140, thereby improving the structural strength of the reinforcing rib structure.

[0038] In some embodiments of this application, such as Figure 4 As shown, the first connecting end 2111 is connected to the midpoint of the second side plate 130 corresponding to the polygonal cell 140. When one end of the first reinforcing rib 211 is connected to the diagonal of the polygonal cell 140 and the other end overlaps the middle of the side, it is beneficial to shorten the length of the first reinforcing rib 211, thereby increasing the strength of the first reinforcing rib 211 and thus improving the overall strength of the reinforcing rib structure. The first connecting end 2111 of the first reinforcing rib 211 overlaps the middle of the second side plate 130 corresponding to the polygonal cell 140, which is beneficial to make the force on the second side plate 130 evenly distributed, thereby improving the load-bearing capacity of the second side plate 130.

[0039] For some embodiments of this application, please refer to [link / reference]. Figure 1 and Figure 2As shown, the second reinforcing structure 220 includes a second reinforcing post 222, which is located at the intersection of two intersecting second reinforcing ribs 221. Specifically, the second reinforcing post 222 is located within the polygonal cell 140, and one end of the second reinforcing post 222 is fixedly connected to the main substrate 110. This facilitates the transfer of force from the second reinforcing rib 221 to the main substrate 110 via the second reinforcing post 222, thereby improving the mechanical stability of the reinforcing rib structure and effectively enhancing its structural strength.

[0040] Furthermore, the second reinforcing column 222 is provided with a slot 2221 extending along the length of the second reinforcing column 222, such as... Figure 2 and Figure 3 As shown. One end of the second reinforcing post 222 is fixedly connected to the main substrate 110. A slot 2221 extending along the length direction is provided in the second reinforcing post 222, which facilitates the transfer of force from the second reinforcing rib 221 to the second reinforcing post 222, thereby improving the strength of the second reinforcing structure 220 and improving the overall strength of the reinforcing rib structure.

[0041] The second reinforcing rib 221 is connected to one side of the first side plate 120, forming the second connecting side 2211. In some embodiments of this application, the height of the second reinforcing rib 221 gradually increases from the second side plate 130 towards the first side plate 120. Furthermore, the contour of the side of the second reinforcing rib 221 away from the main substrate 110 is arc-shaped, such as... Figure 1 and Figure 3 As shown. Thus, the load of the main substrate 110 can be transferred to the first side plate 120 and the second side plate 130 through the second reinforcing rib 221, and the strength of the second reinforcing rib 221 in the length direction of the second reinforcing column 222 can be improved, so as to reduce the possibility of bending or even breaking of the second reinforcing rib 221.

[0042] In some embodiments of this application, see Figure 2 and Figure 4 As shown, the main structure also includes multiple connecting plates 160, which are spaced apart between the first side plate 120 and the second side plate 130. The multiple connecting plates 160, the first side plate 120, and the second side plate 130 form multiple polygonal cells 140. The side of the connecting plate 160 closest to the main substrate 110 is fixedly connected to the main substrate 110, and the bottom outline of the connecting plate 160 matches the main substrate 110. As shown in the figure, two adjacent connecting plates 160, the first side plate 120, and the second side plate 130 form a polygonal cell 140. Each polygonal cell 140 contains a first reinforcing structure 210 or a second reinforcing structure 220. In this embodiment, the polygonal cell 140 is specifically a quadrilateral cell.

[0043] When the distance between two adjacent connecting plates 160 is too large, that is, when the side of the polygonal cell 140 is too long, the reinforcing rib directly overlaps at the diagonal of the polygonal cell 140, which can easily cause the middle of the polygonal cell 140 to become a weak area, resulting in a decrease in the strength of the polygonal cell 140. As one improvement, such as... Figure 4 As shown, by attaching the first connecting end 2111 of one of the first reinforcing ribs 211 to the center of the side of the polygonal cell 140, the strength of the side of the polygonal cell 140 is strengthened, thereby improving the overall strength of the frame.

[0044] In some embodiments of this application, the frame body further includes a third reinforcing structure, which includes a third reinforcing rib. One end of the third reinforcing rib is connected to one diagonal of the polygonal cell 140, and the other end of the third reinforcing rib is connected to the second side plate 130 and located at the midpoint of the side of the polygonal cell 140. This improves the strength between the first side plate 120 and the second side plate 130.

[0045] In some embodiments of this application, the height of the first side plate 120 is greater than the height of the second side plate 130.

[0046] For another embodiment of the vehicle frame in this application, please refer to [link to relevant documentation]. Figures 1 to 4 As shown, the vehicle includes the aforementioned reinforcing rib structure for the frame. Two reinforcing rib structures are symmetrically arranged to form the main body of the frame. The frame also includes a connecting structure 170, which is mounted on the second side plate 130 and is used for connection with the outside. Specifically, one end of the connecting structure 170 is fixedly connected to the second side plate 130, and this connecting structure 170 is used for connection with the outside.

[0047] In this embodiment, the frame also includes a mounting part 150, which connects the reinforcing rib structures on both sides.

[0048] When the connecting structure 170 is connected to the outside, the load can be transferred to the second side plate 130 through the connecting structure 170. As one embodiment, such as... Figure 4 As shown, each polygonal cell 140 near the connecting structure 170 is provided with a first reinforcing structure 210. The first connecting end 2111 of one of the first reinforcing ribs 211 of the first reinforcing structure 210 overlaps with the second side plate 130 corresponding to the polygonal cell 140. This allows the load on the second side plate 130 to be evenly distributed to the area around the connecting structure 170, thereby improving the load-bearing capacity of the second side plate 130 and reducing the deformation of the second side plate 130 due to the load, thus increasing the strength of the frame.

[0049] Furthermore, the connecting structure 170 includes a connecting portion and a supporting portion. One side of the connecting portion is connected to the second side plate 130, and supporting portions are respectively provided on both sides of the connecting portion, and the supporting portions are connected to the second side plate 130. Specifically, the connecting portion is used to fix fasteners to achieve a fixed connection with the outside. For example, the connecting portion is provided with a connecting hole for connecting with fasteners such as bolts, clips, etc. The supporting portion connects the second side plate 130 and the connecting portion, and is used to support the connecting portion to transfer the load of the supporting portion to the second side plate 130.

[0050] In some embodiments of this application, such as Figure 3 As shown, the main substrate 110 includes a horizontally arranged first part 111 and a curved second part 112. The second side plate 130 is aligned with the main substrate 110 in the height direction. The connecting structure 170 is disposed at the position of the second side plate 130 corresponding to the first part 111.

[0051] Another embodiment of this application discloses a vehicle that includes the aforementioned frame and has all the technical effects of the aforementioned frame, which will not be repeated here.

[0052] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
