[0031] This invention provides a dashboard crossbeam.

[0032] In one embodiment, such as Figures 1 to 4As shown, the instrument panel crossbeam 100 is used to connect with the vehicle body, which includes a center tunnel, a front bulkhead, a steering column, a left side bulkhead, and a right side bulkhead. The instrument panel crossbeam 100 includes a main beam 10, a support frame 20, a left end plate 30, a right end plate 40, and a connecting frame 50. The main beam 10 includes a metal frame 11 and a plastic part 12. The metal frame 11 extends along a first direction. The left end plate 30 and the right end plate 40 are located at both ends of the metal frame 11, respectively. The plastic part 12 covers one side of the metal frame 11. The plastic part 12, the left end plate 30, the right end plate 40, and the support frame 20 are integrally injection molded with the metal frame 11 as an insert. The support frame 20 extends along a second direction, which is perpendicular to the first direction. The support frame 20 is used to connect with the center tunnel. The connecting frame 50 is connected with the plastic part 12. The connecting frame 50 is used to connect with the front bulkhead and the steering column. The left end plate 30 is used to connect with the left side bulkhead, and the right end plate 40 is used to connect with the right side bulkhead.

[0033] The first direction is Figure 1 The left and right directions, the second direction is Figure 1 The up and down directions in the middle.

[0034] Please refer to the reference. Figure 1 The metal frame 11 extends in the left-right direction. The left end plate 30 is located at the left end of the metal frame 11, and the right end plate 40 is located at the right end. A plastic part 12 covers the front of the metal frame 11. The metal frame 11 primarily serves to support and shape the structure, and it significantly improves the frontal and side impact performance of the instrument panel crossbeam 100. The plastic part 12, left end plate 30, right end plate 40, and support frame 20 are integrally injection molded with the metal frame 11 as an insert, improving the manufacturing efficiency of the instrument panel crossbeam 100. The support frame 20 extends in the vertical direction and is used to connect with the center channel, thus connecting the instrument panel crossbeam 100 to the center channel. The connecting frame 50 is used to connect with the front bulkhead and steering column, thus connecting the instrument panel crossbeam 100 to the front bulkhead and steering column. The left end plate 30 is used to connect with the left side bulkhead, thus connecting the instrument panel crossbeam 100 to the left side bulkhead. The right end plate 40 is used to connect with the right side panel, thereby connecting the instrument panel beam 100 with the right side panel.

[0035] In this embodiment, the metal frame 11 provides support and load-bearing capacity, meeting the rigidity requirements of the instrument panel crossbeam 100 and significantly improving its frontal and side impact performance, thus enhancing its safety. Furthermore, the plastic parts 12, left end plate 30, right end plate 40, and support frame 20 are integrally injection molded with the metal frame 11 as inserts, reducing the weight of the instrument panel crossbeam 100 and meeting its lightweight requirements.

[0036] The metal skeleton 11 can be made of automotive structural steel, aluminum alloy, magnesium alloy, etc., and the forming process can be conventional metal forming processes such as stamping, welding, and die casting to minimize product costs. The thickness of the metal skeleton 11 depends on the material used, typically ranging from 1mm to 3mm. To ensure a tight bond between the metal skeleton 11 and the injection molded body, the surface of the metal skeleton 11 will be treated, including one or a combination of sandblasting, chemical etching, anodizing, laser processing, and adhesive coating, with anodizing using an acidic solution being preferred. Based on the product's performance and moldability requirements, the injection molding material can be one of PP+60GF, PA6+60GF, PA66+60GF, PA+30CF, or PA+40CF.

[0037] In one embodiment, a mounting groove 111 is provided through the metal frame 11 on the side away from the plastic part 12 along a first direction, and a plurality of reinforcing ribs 13 are integrally injection molded in the mounting groove 111.

[0038] Please refer to the reference. Figure 1 and Figure 3 A mounting groove 111 is provided through the rear side of the metal frame 11 in the left-right direction. Multiple reinforcing ribs 13 are integrally injection molded in the mounting groove 111. The reinforcing ribs 13 enhance the structural stability of the instrument panel crossbeam 100 and improve the safety performance of the instrument panel crossbeam 100. In addition, the mounting groove 111 can reduce the weight of the metal frame 11, making the instrument panel crossbeam 100 even lighter.

[0039] In one embodiment, the metal frame 11 has a plurality of through holes 112, and the plurality of through holes 112 are provided in a one-to-one correspondence with a plurality of reinforcing ribs 13. The metal frame 11 has a connecting section 113 protruding in a direction away from the front cover, and the support frame 20 is disposed on the connecting section 113.

[0040] Please refer to the reference. Figures 1 to 3 Multiple through holes 112 are provided to allow the injection molded part to penetrate the front and rear sides of the metal frame 11 during injection molding, forming a reinforcing rib 13 on the rear side of the metal frame 11. The plastic part 12 and the reinforcing rib 13 clamp the metal frame 11 together, improving the structural strength of the instrument panel crossbeam 100. Specifically, the reinforcing rib 13 has a plastic thickness of 1.5 to 2.5 mm, and the layout of the reinforcing rib 13 follows the principle of gradually changing from dense to sparse from the driver's side to the passenger side, in order to ensure that the product is lightweight while maintaining maximum performance.

[0041] In a preferred embodiment, a covering rib 14 is formed on the plastic part 12. The spacing between the covering ribs 14 is related to the position of the reinforcing rib 13. The covering ribs 14 make the structural strength of the instrument panel beam 100 higher and improve the safety performance of the instrument panel beam 100.
