[0028] Reference below Figure 1-Figure 6 A front connecting beam 100 according to an embodiment of the first aspect of the utility model is described.

[0029] like Figure 1-Figure 6 As shown, the front connecting beam 100 according to the first embodiment of the utility model includes a first connecting portion 1 and a second connecting portion 2.

[0030] Specifically, a first mounting hole 11 is formed on the first connecting portion 1, and the first connecting portion 1 is suitable for connecting to the frame longitudinal beam 201 through the first mounting hole 11. The second connecting portion 2 is arranged on the first connecting portion 1 in a first direction (for example, Figure 1 A second mounting hole 231 and a third mounting hole 2221 are formed on one side of the second connecting portion 2 away from the first connecting portion 1. The second mounting hole 231 and the third mounting hole 2221 are respectively located on the second connecting portion 2 in the second direction (for example, Figure 1 The second connection part 2 is connected to the anti-collision beam 202 through the second mounting hole 231, and the second connection part 2 is connected to the first support beam 203 through the third mounting hole 2221. Figure 1 In the front-to-rear direction, one side surface of the second connection part 2 protrudes from one side surface of the first connection part 1, and one side surface of the second connection part 2 adjacent to the first connection part 1 is suitable for abutting against the frame longitudinal beam 201, and the third direction, the second direction and the first direction are orthogonal to each other.

[0031] For example, in Figure 1 and Figure 2In the example, along the first direction, the first connection part 1 and the second connection part 2 are arranged in sequence, increasing the position of the front connecting beam 100 connecting different structures (such as the frame longitudinal beam 201, the anti-collision beam 202 or the first support beam 203) in the first direction, improving the effect of the front connecting beam 100 integrating and connecting multiple structures, so as to improve the connection efficiency between different structures and the front connecting beam 100, improve the integrity and quality of the frame assembly 200, and also avoid interference between different structures in the first direction. At the same time, the structure of the front connecting beam 100 is suitable for meeting the styling needs of a low wind resistance vehicle body.

[0032] The first connection part 1 is connected to the frame longitudinal beam 201 through the first mounting hole 11, and the second connection part 2 is connected to the anti-collision beam 202 and the first support beam 203 through the second mounting hole 231 and the third mounting hole 2221, which is conducive to improving the installation stability and reliability of the front connecting beam 100 and the frame longitudinal beam 201, the anti-collision beam 202 and the first support beam 203, thereby improving the integrity of the frame assembly 200. The second mounting hole 231 and the third mounting hole 2221 are formed at intervals on both sides of the second direction of the second connection part 2, which can avoid mutual interference between the anti-collision beam 202 and the first support beam 203, thereby improving the connection reliability and stability between the anti-collision beam 202 and the first support beam 203 and the front connecting beam 100.

[0033] The side of the second connection portion 2 facing the frame longitudinal beam 201 protrudes from the surface of the first connection portion 1, thereby forming a step portion between the first connection portion 1 and the second connection portion 2. Therefore, the second connection portion 2 stops against the frame longitudinal beam 201, which is conducive to positioning the frame longitudinal beam 201 and supporting the frame longitudinal beam 201, thereby facilitating the efficiency and reliability of the front connecting beam 100 connecting the frame longitudinal beam 201. In addition, the side of the first connection portion 1 facing the frame longitudinal beam 201 can limit the frame longitudinal beam 201 to prevent the frame longitudinal beam 201 from excessive movement, and can also further ensure the connection stability between the frame longitudinal beam 201 and the front connecting beam 100.

[0034] Optionally, the front connecting beam 100 may be an integrally formed casting structure to improve the integrity of the front connecting beam 100 , thereby improving the structural strength of the front connecting beam 100 .

[0035] Optionally, at least one reinforcing rib 8 is provided on the surface of the second connecting portion 2 facing the frame longitudinal beam 201, and at least part of the reinforcing rib 8 is connected to the first connecting portion 1, and at least part of the reinforcing rib 8 is connected to the second connecting portion 2. The portion of each reinforcing rib 8 connected to the second connecting portion 2 can be connected to at least part of the frame longitudinal beam 201. In this way, the connection stability between the first connecting portion 1 and the second connecting portion 2 of the front connecting beam 100 can be increased, and at the same time, the connection stability between the front connecting beam 100 and the frame longitudinal beam 201 can be increased.

[0036] According to the front connecting beam 100 of the embodiment of the utility model, the design of the first connecting portion 1 and the second connecting portion 2 improves the effect of the front connecting beam 100 in integrating and connecting multiple structures, improves the connection efficiency between different structures and the front connecting beam 100, and improves the integrity and quality of the frame assembly 200. In addition, by making one side surface of the second connecting portion 2 protrude from one side surface of the first connecting portion 1, the positioning and / or limiting effect on the frame longitudinal beam 201 is achieved, the connection stability between the frame longitudinal beam 201 and the front connecting beam 100 is ensured, and the connection efficiency and connection reliability between the frame longitudinal beam 201 and the front connecting beam 100 are improved.

[0037] According to some embodiments of the present invention, referring to Figure 1-Figure 3 , the front connecting beam 100 also includes a third connecting portion 3. The third connecting portion 3 is arranged on one side of the first connecting portion 1 in the second direction, and the third connecting portion 3 extends along the third direction, wherein a fourth mounting hole 31 is formed on the third connecting portion 3, and the third connecting portion 3 is suitable for connecting with the second support beam 204 through the fourth mounting hole 31, and the fourth mounting hole 31 and the second mounting hole 231 are located on the same side of the second direction. The arrangement of the third connecting portion 3 is conducive to increasing the connection position of the front connecting beam 100, so that the third connecting portion 3 is connected with the second support beam 204 through the fourth mounting hole 31 on the third connecting portion 3, further enriching the structure of the front connecting beam 100 connection, and is conducive to increasing the number of structures integrated and connected in the frame assembly 200. The arrangement of the fourth mounting hole 31 and the second mounting hole 231 is conducive to making the second support beam 204 and the anti-collision beam 202 connected to the front connecting beam 100 at intervals, avoiding mutual interference between the second support beam 204 and the anti-collision beam 202, and increasing the orderliness of the frame assembly 200.

[0038] Furthermore, if Figure 1-Figure 3 As shown, the front connecting beam 100 further includes a fourth connecting portion 4, which is arranged on the same side of the first connecting portion 1 in the second direction as the third connecting portion 3, and is located on a side of the third connecting portion 3 away from the second connecting portion 2, wherein the fourth connecting portion 4 extends along the third direction, and a fifth mounting hole 41 is formed on the fourth connecting portion 4, the fifth mounting hole 41 extends along the second direction, and the fourth connecting portion 4 is suitable for connecting to the bumper bracket 205 through the fifth mounting hole 41. The provision of the fourth connecting portion 4 is conducive to increasing the position of the front connecting beam 100 for connecting the bumper bracket 205. The provision of the fifth mounting hole 41 is conducive to stably and reliably connecting the second support beam 204 and the bumper bracket 205 to the front connecting beam 100.

[0039] Furthermore, if Figure 1-Figure 3As shown, the front connecting beam 100 further includes a fifth connecting portion 5. The fifth connecting portion 5 is arranged on the other side of the first connecting portion 1 in the second direction, and the fifth connecting portion 5 extends along the third direction. The fifth connecting portion 5 and the fourth connecting portion 4 are both formed with a sixth mounting hole 51, and the sixth mounting hole 51 extends along the third direction. The fifth connecting portion 5 and the fourth connecting portion 4 are suitable for connecting with the steering bracket 206 or the washing pot bracket 207 through the sixth mounting hole 51. Thus, the fifth connecting portion 5 and the fourth connecting portion 4 are respectively arranged on both sides of the first connecting portion 1 in the first direction, three sixth mounting holes 51 are formed on the fifth connecting portion 5, and three sixth mounting holes 51 are formed on the fourth connecting portion 4. The fifth connecting portion 5 can be connected to the steering bracket 206, and the fourth connecting portion 4 can be connected to the washing pot bracket 207; or the fifth connecting portion 5 can be connected to the washing pot bracket 207, and the fourth connecting portion 4 can be connected to the steering bracket 206. Thus, it is beneficial to increase the number of structures integrated and connected by the front connecting beam 100, that is, the integration effect of the frame assembly 200 is increased by using the front connecting beam 100.

[0040] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the second connecting part 2 includes a first connecting plate 21, two second connecting plates 22 and a third connecting plate 23. The first connecting plate 21 is connected to the first connecting part 1. The two second connecting plates 22 are respectively connected to the two sides of the first connecting plate 21 in the third direction, each second connecting plate 22 extends along the first direction, and each second connecting plate 22 is formed with a third mounting hole 2221. The third connecting plate 23 is connected to one side of the two second connecting plates 22 in the second direction, and the third connecting plate 23 is formed with a second mounting hole 231. In other words, the surface of one side of the first connecting plate 21 away from the second connecting plate 22 and the third connecting plate 23 is suitable for abutting against the frame longitudinal beam 201. The two second connecting plates 22 are arranged oppositely, which can improve the symmetry and force balance of the second connecting part 2, thereby facilitating the use stability of the front connecting beam 100. At the same time, the two second connecting plates 22 are spaced apart, so that the third mounting holes 2221 on the two second connecting plates 22 are spaced apart, thereby increasing the stability and reliability of the second connecting part 2 connecting the first support beam 203. The two sides of the third connecting plate 23 are respectively connected to the two second connecting plates 22, which increases the structural strength of the second connecting part 2 and increases the location of the second mounting hole 231, which is beneficial to the connection between the front connecting beam 100 and the anti-collision beam 202. No components are set on the other side of the two second connecting plates 22 in the second direction, which is beneficial to increase the operating space of the second connecting part 2 and improve the convenience of using the front connecting beam 100. Therefore, while meeting the requirements of the second connecting part 2 connecting the anti-collision beam 202 and the first support beam 203 and ensuring the structural strength of the second connecting part 2, it is beneficial to the lightweight design of the second connecting part 2.

[0041] Further, refer to Figure 1-Figure 3Each second connecting plate 22 includes a support plate 221 and an extension plate 222. The support plate 221 extends along the first direction. The extension plate 222 is arranged on a side of the support plate 221 away from the third connecting plate 23. The extension plate 222 extends along the third direction. A third mounting hole 2221 is formed on the extension plate 222. A protruding plate 6 is arranged on a side of the extension plate 222 away from the third connecting plate 23. A seventh mounting hole 61 is formed on the protruding plate 6. The protruding plate 6 is suitable for connecting with the cooling module 208 through the seventh mounting hole 61. That is, the support plate 221 is connected with the first connecting plate 21 and the third connecting plate 23. The extension plate 222 and the protruding plate 6 are arranged on a side of the support plate 221 away from the third connecting plate 23 along the second direction. Thus, the distance between the second connecting plate 22 and the anti-collision beam 202 and the cooling module 208 is reduced, which is conducive to the connection of the second connecting plate 22 with the anti-collision beam 202 and the cooling module 208. At the same time, the second mounting hole 231 on the extension plate 222 is connected to the anti-collision beam 202, and the seventh mounting hole 61 on the protruding plate 6 is connected to the cooling module 208, which is beneficial to avoid mutual interference between the anti-collision beam 202 and the cooling module 208, and further helps to improve the connection reliability between the front connecting beam 100 and the anti-collision beam 202 and the cooling module 208.

The ninth mounting hole 232 on the third connecting plate 23 is spaced apart from the second mounting hole 231 in the first direction to avoid interference between the bumper frame and the anti-collision beam 202, thereby facilitating the improvement of the connection reliability and stability of the front connecting beam 100 and the bumper frame and the anti-collision beam 202.

[0043] According to some embodiments of the utility model, a portion of the surface of each second connecting plate 22 on the side away from the third connecting plate 23 in the second direction is recessed toward the third connecting plate 23; and / or a portion of the surface of each second connecting plate 22 on the side adjacent to the third connecting plate 23 in the second direction is recessed away from the third connecting plate 23.
