In the description of the present invention, it should be noted that, if terms indicating orientation or positional relationship such as "upper", "lower", "inner", "back", etc. appear, they are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the appearances of the terms first, second, etc. in this specification are not necessarily all referring to the same item, but are instead intended to cover the same item.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example one

The embodiment relates to an instrument board cross beam, the whole structure of which comprises a main beam and an auxiliary beam which are connected in a matching way in different radial cross section areas, and the central lines of the main beam and the auxiliary beam are arranged in parallel and at intervals. The integral structure is simple, and space is provided for arranging peripheral parts of the secondary beam. In addition, because the secondary beam is subjected to bending or structural dent weakening treatment, the possibility of deformation generated when the secondary beam is impacted is reduced, and the stress of the secondary beam is uniform.

Based on the above-mentioned overall design concept, an exemplary structure of the instrument panel beam applied to a vehicle of the present embodiment is shown in fig. 1 to fig. 3, where the instrument panel beam 1 includes a main beam 101 and a sub-beam 102, the main beam 101 and the sub-beam 102 are connected in a matching manner with different radial cross-sectional areas, and the center lines of the two are parallel and spaced, preferably, the distance value D between the center lines of the main beam 101 and the sub-beam 102 is 10mm to 13.5mm, such as 12mm, that is, a safety gap can be properly avoided for peripheral air conditioners and other electrical devices, and the problems of interference, difficult assembly and the like caused by a small gap in actual assembly can be reduced.

In order to ensure the overall rigidity of the sub-beam 102, in the present embodiment, the sub-beam 102 is configured to extend in the vehicle body width direction with a constant radial cross-sectional area. It can be understood that, because the distance arrangement is formed between the central lines of the main beams 101 and the secondary beams 102, the arrangement replaces the concave structure of the secondary beams 102, that is, the pipe diameters of the secondary beams 102 are consistent, which makes the stress of the secondary beams 102 more uniform, and then improves the rigidity of the secondary beams 102, so that the secondary beams 102 are not easy to break.

In order to reduce the weight of the entire cross member, in the present embodiment, the main beams 101 and the sub-beams 102 are each configured as a tubular structure; further preferably, the wall thickness T of the primary beam 101 and the secondary beam 102 is defined between 1.5mm and 2.0mm, for example, the wall thickness T may be set to 1.8 mm.

The lower contour lines of the main beam 101 and the auxiliary beam 102 are overlapped, the structural adjustment space can be enlarged, the problem of difficult assembly caused by small gaps in the actual assembly of the vehicle is further reduced, in addition, the rigidity of the main beam 101 is enhanced by the eccentric structure of the main beam 101, and the auxiliary beam 102 is replaced to be locally avoided, so that the rigidity of the auxiliary beam 102 is further improved.

In order to avoid the perimeter member, a transition beam 2 is formed between the main beam 101 and the secondary beam 102, and the transition beam 2 constitutes a connection from the outer contour of the main beam 101 to the outer contour of the secondary beam 102. Referring to fig. 3, the transition beam 2 includes a first insertion portion 201 inserted and matched with the main beam 101, a transition portion 202 and a second insertion portion 203 inserted and matched with the secondary beam 102, the transition portion 202 is connected in a conical transition manner along the first insertion portion 201 towards the second insertion portion 203, and the transition portion 202 is connected in a rounded connection manner at the diameter change position. Generally, the main beam 101 and the auxiliary beam 102 are spliced through a pipe expanding or pipe contracting process, and then welded and fixed through gas shielded welding; the main beam 101 and the auxiliary beam 102 are in transition connection under the condition that the central lines are inconsistent, stress concentration is reduced, local depression of the auxiliary beam 102 is avoided, the rigidity of the auxiliary beam 102 is improved, and the integral rigidity of the instrument panel cross beam 1 is increased.
