Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard crossbeam technology, and in particular to an automotive dashboard crossbeam steering column bracket assembly. Background Technology

[0002] The steering column and steering wheel are installed in the driver's seat of a car. The dashboard crossbeam has a steering column bracket at the steering column location and is a core component connecting the dashboard crossbeam to the car body. Existing dashboard crossbeams utilize methods such as... Figure 1 The single main beam 1' shown is shown, and the steering column bracket 2' is divided into upper and lower brackets that are directly welded to the main beam 1', and has only one mounting point with the vehicle body. Figure 1 The mounting point for the vehicle body is located at the upper center rear side. Because the steering column bracket 2' is prone to wobbling and thermal deformation during welding, its strength and precision are relatively poor. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned technical problems, this utility model provides an automotive dashboard crossbeam steering column bracket assembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a steering column bracket assembly for an automotive dashboard crossbeam, comprising a double main beam and a steering column bracket. The double main beam includes an upper main beam and a lower main beam, which are connected to each other to form a frame structure. The upper and lower main beams are arranged horizontally in the vertical direction. The steering column bracket includes a left bracket and a right bracket symmetrically arranged, which are respectively located at the left and right ends of the automotive steering column. The left and right brackets are connected to each other by a support beam, which is arranged horizontally between the left and right brackets. Both the left and right brackets are plate-shaped and vertically mounted on the double main beams. The upper side of both the left and right brackets has upper main beam mounting holes, and both the left and right brackets are connected and fixed to the upper main beam at their upper main beam mounting holes. The lower end of both the left and right brackets has lower main beam mounting holes, and both the left and right brackets are connected and fixed to the lower main beam at their lower main beam mounting holes. Both the left and right brackets are fixed to the front of the vehicle body. Both the left and right brackets have steering column mounting point areas, which protrude from the space between the upper and lower main beams.

[0005] To improve installation accuracy, both the left and right supports are bolted to the upper main beam at the mounting holes of the upper pipe beam, and both the left and right supports are bolted to the lower main beam at the mounting holes of the lower pipe beam.

[0006] To improve installation accuracy, mounting bushings are installed on both the left and right brackets at positions facing the front of the vehicle body, and both the left and right brackets are fixed to the front of the vehicle body with bolts at the mounting bushings.

[0007] The steering column mounting points of the left and right brackets are equipped with flanged structures to prevent the steering column from sinking during installation.

[0008] Both the left and right brackets are equipped with sheet metal sheets, which are located on the back of the steering column mounting point area of ​​the left or right bracket. The steering column mounting point area is the stress point of the steering shaft. The design of the sheet metal sheets greatly increases the overall strength of the steering column bracket, avoiding insufficient strength caused by the steering column bracket continuously bearing the stress of the steering shaft, and preventing the bracket from cracking and the mounting point from loosening due to repeated stress, which could lead to abnormal noise and functional failure.

[0009] Preferably, the sheet metal sheet has a thickness of 5mm.

[0010] Preferably, the sheet metal sheet is welded to the left and right brackets.

[0011] To reinforce the lower main beam at the driver's position, a lower mounting bracket is also included, which is bolted to the lower main beam.

[0012] To facilitate the connection between the automotive dashboard crossbeam steering column bracket assembly of this utility model and the vehicle body, lower tube bushings are provided at both ends of the lower main beam, and each end of the lower main beam is fixed to the side panel of the vehicle body by a long bolt, thereby increasing the overall modality of the automotive dashboard crossbeam.

[0013] Preferably, each end of the lower main beam is fixed to the side panel of the vehicle body by a long hexagonal flange bolt.

[0014] The beneficial effects of this utility model are as follows: The automotive dashboard crossbeam steering column bracket assembly of this utility model adopts a structure in which a double main beam is connected to the steering column bracket. The upper and lower main beams of the double main beams are connected to each other to form a frame structure, resulting in good overall stability of the dashboard crossbeam. The steering column bracket is fixed to the front of the vehicle body through two mounting points, left and right brackets, which disperses the resonance vibration force and makes the structure more robust. The support beam is horizontally arranged between the left and right brackets, and is then connected to the upper and lower main beams through the left and right brackets respectively, so that the steering column bracket as a whole forms a stable frame structure. The left and right brackets are respectively located at the left and right ends of the automotive steering column. After the left and right sides are separated, the force is not so concentrated, making the force on the steering column more balanced and preventing stress concentration from causing the steering column bracket to crack during a collision.

The lower tube beam mounting hole 7 is located on the front side of the lower end of the left bracket 3 or the right bracket 4 and is fixed to the rear side of the lower main tube beam 2 facing the front of the vehicle body. Figure 2 As shown, the left bracket 3 and the right bracket 4 have portions that extend into and protrude from the space between the upper main beam 1 and the lower main beam 2. The portion that protrudes from the space between the upper main beam 1 and the lower main beam 2 is the steering column mounting point area.

[0025] Both the left bracket 3 and the right bracket 4 are bolted to the upper main beam 1 at the mounting hole 6 on the upper tube beam, and both are bolted to the lower main beam 2 at the mounting hole 7 on the lower tube beam.
