Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and specifically relates to an instrument tube beam structure and a vehicle. Background Art

[0002] With the development of intelligent and automated technologies in the entire manufacturing industry, the intelligence and automation of vehicles are becoming more and more popular among consumers. Among them, head-up displays and electronic steering wheels are an important product of vehicle intelligence and automation in recent years. While bringing comfort and convenience to drivers, they also bring new problems.

[0003] Both the head-up display and the electronic steering wheel need a carrier to carry and install them. As the load-bearing carrier of the vehicle instrument, the instrument beam is not only used to install and fix the instrument panel, but also to install and fix the emerging head-up display and electronic steering wheel. If the instrument beam has low stiffness and insufficient deformation resistance, it is easy to cause the entire instrument to vibrate on a bumpy road. What's worse, it may coincide with the steering wheel mode, causing resonance problems such as steering wheel shaking and numbness.

[0004] Therefore, for vehicles equipped with both a head-up display and an electronically controlled steering wheel, the rigidity and strength of the instrument beam are crucial. The mass of the head-up display is approximately in the range of 1.5kg-3kg, and the head-up display is usually supported and fixed by a head-up display bracket connected to the instrument beam. In this way, the head-up display bracket is similar to a cantilever structure. When subjected to external excitation, the head-up display bracket carrying a certain mass will swing to a certain extent due to insufficient rigidity and strength. In this way, the vehicle speed, navigation and other information projected onto the front windshield will be greatly disturbed, which in turn affects the driving experience and reduces the quality of the vehicle.

[0005] The steering column also has an installation point on the instrument panel, and because it is an electric steering wheel, an additional motor is needed to control it. In addition, due to driving requirements, the installation of the head-up display and the steering column has a certain overlap in space. How to balance the head-up display bracket and the column bracket and strengthen them requires key design.

[0006] Multiple instrument panel mounting brackets are arranged on the instrument tube beam, but the design and arrangement of the existing brackets are unreasonable, resulting in insufficient strength of the instrument, and then the overall modal of the instrument is low, and the instrument will vibrate when the vehicle is driving on a bumpy road.

[0007] For example, the patent document with publication number CN112298374A discloses an instrument tube beam assembly. The instrument tube beam assembly includes: a first tube beam corresponding to the main driving position; a second tube beam corresponding to the co-driving position; a connecting piece is provided between the first tube beam and the second tube beam; the connecting piece includes a flat abutment surface for the first tube beam and / or the second tube beam to select a fixed position. This solution adds a connecting piece to the first tube beam and the second tube beam, so that the first tube beam and the second tube beam are fixed on the connecting piece respectively, and eliminates the existing conical transition surface between the first tube beam and the second tube beam. The technical solution disclosed in this patent document also cannot solve the technical problems described above. Utility Model Content
