Description

Beam structure of automobile instrument board

As disclosed in chinese patent CN214325227U, the prior art including the patent discloses a "connecting bracket and automobile for connecting a beam of an automobile dashboard with a steering column", wherein the beam structure of the automobile dashboard is formed by directly welding a mounting support (a support in the present utility model) and a beam of the automobile dashboard (a tubular beam in the present utility model), and in order to ensure stability of the structure and meet rigidity requirements, the mounting support and the beam are generally made of metal materials; the general crossbeam can adopt steel metal to make, because the direct welding of different metal materials will produce the condition of harmony, so the erection support also need to adopt steel metal to make, this makes the whole quality of instrument board crossbeam higher, can't satisfy the demand of lightweight.

Furthermore, the beam structure made of the combined magnesium-aluminum materials can realize light weight, but the cost of the aluminum-magnesium alloy is higher, so that the beam structure is in a high-end vehicle shape generally, and the economic benefit is poor. In order to reduce cost and mass applicability, the existing beam structure is usually made by combining an aluminum pipe beam and a plastic part or combining the pipe beam and the plastic part, but the supporting strength of the beam structure is lower due to lower hardness of the plastic part, and the beam structure may deform after long-term use, so that the use of a vehicle is affected.

In order to solve the above problems, designing a beam structure of a vehicle instrument panel that meets both requirements of light weight and rigidity is an important technical problem to be solved by those skilled in the art at present.

In the description of the scheme, the direction approaching the operator is the near end, and the direction separating from the operator is the far end, with reference to the operator.

As shown in fig. 1, the present utility model discloses a cross beam structure of a vehicle instrument panel, which comprises a steel tubular beam 1 and an aluminum support 2. In order to make the beam structure connection more stable, a notch matched with the outer contour of the tubular beam 1 is preferably formed on the supporting piece 2 in the utility model. In the utility model, the tubular beam 1 and the supporting piece 2 are both made of metal materials, and compared with the prior art adopting aluminum-plastic combination, the tubular beam has higher hardness and higher supporting and bearing capacity. The utility model adopts the steel-aluminum combination to manufacture the beam structure of the vehicle instrument board, and compared with the magnesium-aluminum combination, the beam structure has lower cost and is more beneficial to improving the economic benefit.

Further, as shown in fig. 1 to 2, in order to avoid the mutual influence of corrosion and the like caused by direct welding of the tubular beam 1 and the support 2 made of different metal materials, in the present utility model, it is preferable to provide a connection plate 3 on the support 2, and the connection plate 3 is preferably a galvanized plate. The connecting plate 3 is U-shaped, and the top of the connecting plate is higher than the top end of the supporting piece 2 and is fixedly connected with the outer contour of the tubular beam 1. Through set up in connecting plate 3 on support piece 2 with tubular beam 1 welds, effectively avoids support piece 2 with the condition that the steel aluminium that tubular beam 1 lug connection caused combines harmony. Further, the top ends of the two side walls, which are abutted to the supporting piece 2, of the connecting plate 3 are provided with clamping grooves matched with the outer contour of the tubular beam 1. The clamping groove at the top end of the connecting plate 3 is abutted with the outer wall of the tubular beam 1, so that the mounting stability of the two is improved.
