[0038] refer to figure 1 and figure 2 , this embodiment provides a new instrument panel beam assembly, including:
[0039] A crossbeam 1, the length direction of the crossbeam 1 is parallel to the vehicle width direction AA, the crossbeam 1 is connected to the side panels 3 on both sides of the vehicle along the vehicle width direction AA, and is connected to the dash panel 4 along the vehicle front and rear direction BB;
[0040] The connector 2 arranged at one end of the beam 1 along the length direction, the connector 2 has a first part 21 connecting the beam 1 along the length direction of the beam 1, a second part 22 for connecting the side panel 3 of the vehicle, and a second part 22 located at the first part 21. and the deformation portion 23 between the second part 22, one end of the beam 1 is connected to the side panel 3 on one side through the connecting piece 2, and the other end is directly connected to the side panel 3 on the other side (not shown in the figure...

[0056] Compared with the first embodiment, the second embodiment differs in that:
[0057] refer to Figure 5 and Image 6 , the deformation part 33 is designed as:
[0058] The first part 31 and the second part 32 are staggered along the front-rear direction BB of the car, and the first part 31 is closer to the rear part II of the car along the front-rear direction BB than the second part 32 . At this time, the deformation part 33 connects the first part 31 and the second part 32 along the front and rear direction BB of the vehicle;
[0059] The connection position D' between the first part 31 and the deformation part 33 and the connection position E' between the second part 32 and the deformation part 33 are all stress concentration areas, which are easy to deform.
[0060] The first part 31 has a first installation surface 310 for installing the beam 1 , the second part 32 has a second installation surface 320 for installing the side panel 5 , and the deformation part 33...

[0066] Compared with the first embodiment and the second embodiment, the third embodiment differs in that:
[0067] refer to Figure 7 , the connector 4 is in the form of a plate as a whole, and the plate surface 40 of the connector 4 is perpendicular to the height direction of the vehicle, wherein the deformation part 43 is designed as:
[0068] The deformation portion 43 is provided with through holes 430 distributed along the front and rear direction BB of the vehicle and penetrating along the height direction of the vehicle, that is, the through holes 430 penetrate through the plate surface 40 . Due to the reason of the through hole 430, the density of the deformed part 43 is lower than the density of the first part 41 and the second part 42 on both sides, the rigidity of the deformed part 43 is lower than the rigidity of the first part 41 and the second part 42, and the deformed part 43 is lower than that of the first part 41 and the second part 42. The part 41 and the s...
