[0002] Currently, most composite instrument panel crossbeams on the market employ a combination of metal and plastic structures. The main crossbeam is a rectangular extruded tubular profile structure, while the front support bracket uses injection-molded parts, die-cast aluminum alloy, or die-cast magnesium alloy assembly. However, the steering column system is located far from the instrument panel crossbeam, and the torque it generates can affect the product's structural performance. With the intelligent development of new energy vehicles, the instrument panel crossbeam needs to simultaneously support components such as the steering column, HUD (head-up display) module, and large screen module. This leads to an increase in the volume and weight of the instrument panel crossbeam, and its distance from the main beam creates a cantilever beam structure, severely impacting the product's structural performance and increasing the difficulty of subsequent design and optimization.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides an instrument panel crossbeam, comprising: a main crossbeam 1 and an instrument panel frame 2. The instrument panel frame 2 is fitted onto the outside of the main crossbeam 1.

[0034] The main crossbeam 1 is arranged along the width direction of the vehicle, and the main crossbeam 1 is provided with a bending part 11 and a second mounting part 12. The cross section of the main crossbeam 1 is rectangular, and the main crossbeam 1 is made of aluminum alloy extrusion molding.

[0035] The main crossbeam 1 is equipped with a bend 11, making its overall structure more compact. The bend 11 is close to the large screen module and the steering column, which not only ensures that the performance of the main crossbeam 1 meets the modal requirements, but also provides sufficient space for the installation of components. At the same time, the design of the bend 11 also provides ample space for deformation energy absorption, thereby effectively improving safety performance.

[0036] In this embodiment, the end of the dashboard frame 2 located on the driver's side is defined as the left side, and the end located on the passenger side is defined as the right side. Simultaneously, the direction of the vehicle's front is defined as the front of the vehicle, the direction of the rear of the vehicle is defined as the rear of the vehicle, and the direction of the vehicle towards the ground is defined as the bottom of the vehicle.

[0037] The instrument panel frame 2 includes a crossbeam sleeve 21, a steering column bracket 26, a body floor bracket 27, a front body bracket 28, and a first bracket 22, a second bracket 23, a third bracket 24, and a fourth bracket 25 arranged sequentially from left to right on the crossbeam sleeve 21. The crossbeam sleeve 21 is fitted onto the outside of the main crossbeam 1 and has a hollow structure. This hollow structure allows the crossbeam sleeve 21 to cover the main crossbeam 1 while also saving materials and reducing weight.

[0038] The crossbeam sleeve 21, first bracket 22, second bracket 23, third bracket 24, and fourth bracket 25 are integrally injection molded from PA6GF60 material. Specifically, the main crossbeam 1 is placed in the injection mold, and the crossbeam sleeve 21, first bracket 22, second bracket 23, third bracket 24, and fourth bracket 25 are injection molded. After molding, the steering column bracket 26 is connected to the second bracket 23, the body floor bracket 27 is connected to the third bracket 24, and the front body bracket 28 is connected to the crossbeam sleeve 21.

[0039] The first bracket 22 is located on the left side of the bend 11 and extends downwards towards the vehicle. The first bracket 22 includes a left mounting bracket 221 and a sub-frame 222.

Two first steering column connection points 232 are located on the lower surface of the second bracket 23 for connecting to the steering column. The second bracket 23 has a mesh structure. The mesh structure is used to achieve crushing, absorbing energy in the vehicle's direction of travel. During a vehicle collision, it utilizes the internal energy generated by structural crushing deformation to balance the kinetic energy generated during the collision, thereby ensuring that the main crossbeam 1 does not experience significant lateral deformation in the vehicle's direction of travel, protecting the driver's safety, and improving the overall vehicle's passive safety performance.

[0041] The steering column bracket 26 is fitted onto the outside of the main crossbeam 1 and connected to the second bracket 23 via the second mounting part 12. The steering column bracket 26 is located behind the second bracket 23 and extends rearwards towards the vehicle. The steering column bracket 26 has two second steering column connection points 261, which, along with two first steering column connection points 232, connect to the steering column. The steering column bracket 26 is made of extruded aluminum profile.

[0042] The third bracket 24 is located at the bend 11 and extends downwards from the vehicle. The third bracket 24 includes two side frames 241 and three bracket crossbeams 242, which are spaced apart between the two side frames 241. The fixed ends of the two side frames 241 are connected to the crossbeam sleeves 21. Four large screen module mounting points 243 are provided on the two side frames 241 for connecting the large screen modules. Three air conditioning module mounting points 244 are provided on the two side frames 241 for connecting the air conditioning modules.

[0043] There are two vehicle floor brackets 27, each corresponding to one side frame 241 and installed on the outside of the side frame 241. Each vehicle floor bracket 27 is provided with two floor connection points 271 for connecting to the vehicle floor. The vehicle floor brackets 27 are made of stamped aluminum sheet.

[0044] The fourth bracket 25 is located on the right side of the bend 11 and includes a PAB (airbag) mounting bracket 251, a glove box bracket 252, and a right mounting bracket 253.

[0045] PAB mounting bracket 251 extends rearwards from the vehicle. PAB mounting bracket 251 is a connecting post with a downward opening; one end of the connecting post is connected to the crossbeam sleeve 21, and the other end is provided with a mounting point for connection to the PAB. In this embodiment, there are two PAB mounting brackets 251.

[0046] The glove box bracket 252 extends downwards from the vehicle. The glove box bracket 252 has a U-shaped structure, and together with the crossbeam sleeve 21, it forms an annular frame structure with a second mounting opening 254. The glove box is disposed within the second mounting opening 254 and connected to the glove box bracket 252.

[0047] The right mounting bracket 253 has three right body connection points for connecting to the right side of the vehicle body.

[0048] The front bulkhead bracket 28 is detachably connected to the crossbeam sleeve 21 and includes a connecting frame 281 and a front bulkhead bracket 282. The connecting frame 281 and the crossbeam sleeve 21 together form an annular frame structure with a third mounting port 284. The front bulkhead bracket 282 is located at the front end of the connecting frame 281 and has a second front bulkhead connection point 283. The first front bulkhead connection point 231 and the second front bulkhead connection point 283 are connected to the front bulkhead of the vehicle body. The front bulkhead bracket 28 is made of stamped aluminum sheet. The third mounting port 284 is used to install the main unit of the multi-functional media unit.

[0049] Through the detachable connection design of the front bulkhead bracket 28, during a vehicle collision, the front bulkhead bracket 28 absorbs the collision kinetic energy through crushing deformation, converting it into internal energy. This deformation process balances the collision impact and effectively suppresses the lateral deformation of the main crossbeam 1 in the vehicle width direction. Ultimately, this ensures the integrity of the driver's survival space and improves the overall passive safety performance of the vehicle.

[0050] In this embodiment, the first bracket 22, the third bracket 24 and the fourth bracket 25 of the instrument panel frame 2 are all provided with instrument panel mounting points 29 for connecting the instrument panel modules at the positions corresponding to the instrument panel modules.

[0051] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
