In one aspect, a reinforcement structure for a vehicle frame is disclosed, as shown in fig. 1-4, and includes a main body structure and a reinforcement assembly.

Specifically, as shown in fig. 1 to 4, the main body structure includes a main body substrate 110, a first side plate 120 and a second side plate 130, wherein the first side plate 120 and the second side plate 130 are disposed on the main body substrate 110 at intervals from outside to inside, and a plurality of polygonal unit cells 140 are formed between the first side plate 120 and the second side plate 130. Wherein the first side plate 120 and the second side plate 130 constitute sides of the polygonal unit cell 140 at corresponding positions.

It should be appreciated that the foregoing "inside-out" is with respect to the virtual cut line A-A of the frame. For example, in the present embodiment, the second side plate 130 is closer to the required section line A-A than the first side plate 120, and the first side plate 120 is located at the inner side and the second side plate 130 is located at the outer side.

Referring to fig. 4, the reinforcement assembly includes a first reinforcement structure 210 and a second reinforcement structure 220, and the first reinforcement structure 210 or the second reinforcement structure 220 is disposed in at least one polygonal unit cell 140. The first reinforcing structure 210 includes first reinforcing ribs 211 disposed in a crossing manner, wherein one end of the first reinforcing ribs 211 disposed in a crossing manner is a first connection end 2111, and the first connection end 2111 overlaps the second side plate 130 and is located in the middle of the polygonal unit cell 140; the second reinforcement structure 220 includes second reinforcement ribs 221 disposed to cross each other, and ends of the second reinforcement ribs 221 are connected to opposite corners of the polygonal unit cells 140. Specifically, each first reinforcing structure 210 includes two first reinforcing ribs 211, wherein two ends of one first reinforcing rib 211 are respectively connected to opposite corners of the polygonal unit cell 140, one end of the other first reinforcing rib 211 is connected to the opposite corner of the polygonal unit cell 140 close to the first side plate 120, and the other end, that is, the first connecting end 2111 is overlapped at the middle of the second side plate 130 corresponding to the polygonal unit cell 140. It should be understood that the second side plate 130 corresponding to each polygonal unit cell 140 forms a side edge of the polygonal unit cell 140, and the first connection end 2111 is overlapped at the middle of the side edge; "middle" refers to a position between both ends of the sides of the polygonal unit cell 140.

In the embodiment of the utility model, the polygonal unit cell 140 is formed on the main structure of the reinforcing rib structure, and the first reinforcing structure 210 or the second reinforcing structure 220 is disposed in the polygonal unit cell 140, so as to effectively improve the structural strength of the reinforcing rib structure.

One end of one first reinforcing rib 211 of the first reinforcing structure 210 is connected to a diagonal position of the polygonal unit cell 140, and the other end, i.e., the first connecting end 2111, is overlapped with the middle of the polygonal unit cell 140, so that the structural strength of the polygonal unit cell 140 is improved, and the situation that the side edge of the polygonal unit cell 140 is bent and deformed or concavely deformed is effectively reduced. The first connection ends 2111 of the first reinforcing ribs 211 overlap the middle of the second side plate 130 corresponding to the polygonal unit cell 140, which is beneficial to uniformly distributing the stress of 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 disposed in the polygonal unit cell 140, the stability of the polygonal unit 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 position of the polygonal unit cell 140 and the other end is overlapped with the middle part of the side edge, the length of the first reinforcing rib 211 is advantageously shortened, so that the strength of the first reinforcing rib 211 is improved, and the overall strength of the reinforcing rib structure is further improved. The second reinforcing structure 220 includes the ends of the second reinforcing ribs 221 disposed in a crossing manner connected to the diagonal positions of the polygonal unit cells 140, which is advantageous for improving the structural strength of the polygonal unit cells 140, thereby improving the structural strength of the reinforcing rib structure.

In some embodiments of the present utility model, as shown in fig. 4, the first connection end 2111 is connected to a midpoint of the second side plate 130 corresponding to the polygonal unit cell 140. When one end of the first reinforcing rib 211 is connected to the diagonal position of the polygonal unit cell 140 and the other end is overlapped with the middle part of the side edge, the length of the first reinforcing rib 211 is advantageously shortened, so that the strength of the first reinforcing rib 211 is improved, and the overall strength of the reinforcing rib structure is further improved. The first connection ends 2111 of the first reinforcing ribs 211 overlap the middle of the second side plate 130 corresponding to the polygonal unit cell 140, which is beneficial to uniformly distributing the stress of the second side plate 130, thereby improving the load bearing capacity of the second side plate 130.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the second reinforcing structure 220 includes a second reinforcing column 222, where the second reinforcing column 222 is located at the intersection of two intersecting second reinforcing ribs 221. Specifically, the second reinforcement columns 222 are located in the polygonal unit cells 140, and one ends of the second reinforcement columns 222 are fixedly connected to the main substrate 110. Thereby, the stress of the second reinforcing rib 221 is advantageously transmitted to the main body substrate 110 through the second reinforcing column 222, so that the mechanical stability of the reinforcing rib structure is improved, and the structural strength of the reinforcing rib structure can be effectively improved.

Further, the second reinforcement column 222 is provided therein with a slot 2221 extending along the length direction of the second reinforcement column 222, as shown in fig. 2 and 3. One end of the second reinforcing column 222 is fixedly connected with the main substrate 110. The slots 2221 extending along the length direction are arranged in the second reinforcing column 222, which is favorable for transmitting the stress of the second reinforcing ribs 221 to the second reinforcing column 222, thereby improving the strength of the second reinforcing structure 220 and being favorable for improving the overall strength of the reinforcing rib structure.

The side of the second stiffener 221 connected to the first side plate 120 is a second connection side 2211. In some embodiments of the present utility model, the second side plate 130 points toward the first side plate 120, and the height of the second reinforcing rib 221 increases gradually. Further, the profile of the second reinforcing rib 221 on the side away from the main body substrate 110 is in an arc shape as shown in fig. 1 and 3. Accordingly, the load of the main body substrate 110 can be transmitted to the first side plate 120 and the second side plate 130 via the second reinforcing ribs 221, and the strength of the second reinforcing ribs 221 in the longitudinal direction of the second reinforcing columns 222 can be increased, so that the bending and breakage of the second reinforcing ribs 221 can be reduced.

In some embodiments of the present utility model, referring to fig. 2 and 4, the main structure further includes a plurality of connection plates 160, the plurality of connection plates 160 are disposed between the first side plate 120 and the second side plate 130 at intervals, and the plurality of connection plates 160, the first side plate 120 and the second side plate 130 enclose a plurality of polygonal unit cells 140. One side of the connecting plate 160, which is close to the main body substrate 110, is fixedly connected with the main body substrate 110, and the bottom contour of the connecting plate 160 is matched with the main body substrate 110. As shown in the drawing, two adjacent connecting plates 160, the first side plate 120 and the second side plate 130 enclose a polygonal unit cell 140, and a first reinforcing structure 210 or a second reinforcing structure 220 is disposed in each polygonal unit cell 140. In this embodiment, the polygonal unit cell 140 is specifically a quadrangular unit cell.

When the interval between the adjacent two connection plates 160 is too large, i.e., the side of the polygonal unit cell 140 is long, the reinforcing ribs are directly overlapped at the diagonal corners of the polygonal unit cell 140, which easily results in that the middle position of the polygonal unit cell 140 becomes a weak area, resulting in a decrease in the strength of the polygonal unit cell 140. As an improvement, as shown in fig. 4, the first connection end 2111 of one first reinforcing rib 211 is overlapped with the center of the side of the polygonal unit cell 140, so that the strength of the side of the polygonal unit cell 140 is reinforced, thereby being beneficial to improving the overall strength of the vehicle frame.

In some embodiments of the present utility model, the frame body further includes a third reinforcing structure, wherein the third reinforcing structure includes a third reinforcing rib, one end of the third reinforcing rib is connected to one of the opposite corners of the polygonal unit cell 140, and the other end of the third reinforcing rib is connected to the second side plate 130 and is located at a midpoint of a side edge of the polygonal unit cell 140. Thereby, the strength between the first side plate 120 and the second side plate 130 is advantageously improved.

In some embodiments of the utility model, the height of the first side panel 120 is greater than the height of the second side panel 130.

Referring to fig. 1 to 4, the frame according to another embodiment of the present utility model includes the aforementioned reinforcement rib structure for a frame, where the two reinforcement rib structures are symmetrically disposed to form a frame body, and the frame further includes a connection structure 170, where the connection structure 170 is mounted on the second side plate 130, and the connection structure 170 is used for connection with the outside. Specifically, one end of the connection structure 170 is fixedly connected to the second side plate 130, and the connection structure 170 is used for external connection.

In this embodiment, the frame further includes a mounting portion 150, and the mounting portion 150 connects the reinforcing rib structures on both sides.

When the connection structure 170 is connected to the outside, a load can be transmitted to the second side plate 130 through the connection structure 170. As one embodiment, as shown in fig. 4, the polygonal unit cells 140 near the connection structure 170 are each provided with a first reinforcing structure 210, and the first connection end 2111 of one first reinforcing rib 211 of the first reinforcing structure 210 is overlapped with the second side plate 130 corresponding to the polygonal unit cell 140. Therefore, the load borne by the second side plate 130 can be uniformly dispersed to the area around the connecting structure 170, which is beneficial to improving the load capacity of the second side plate 130, reducing the deformation of the second side plate 130 caused by the load, namely improving the strength of the frame.

Further, the connection structure 170 includes a connection portion and a support portion, one side of the connection portion is connected with the second side plate 130, both sides of the connection portion are respectively provided with the support portion, and the support portion is connected with the second side plate 130.
