Description

Technical Field

[0001] This utility model relates to the field of steering column technology, specifically a steer-by-wire steering column. Background Technology

[0002] The steering column is the core mechanical component of a vehicle steering system. Its functions include transmitting steering torque to the driver, adjusting the steering wheel position, and absorbing collision energy. According to the power assistance method, it can be divided into three main types: mechanical, hydraulic power-assisted, and electro-hydraulic power-assisted. Among them, the mechanical steering column must meet the technical specifications of the mechanical steering column group standard.

[0003] The patent CN222062078U discloses a steer-by-wire column, which discloses a height-adjustable technical solution. This solves the problem that the existing steer-by-wire columns cannot be height-adjusted, which is undoubtedly a considerable problem for drivers who are tall or short, and cannot improve their practicality and driver comfort.

[0004] When the device is in use, the support rod angle changes as the connecting pipe 2 and housing 2 rise, increasing the steering wheel distance. However, as the steering wheel distance increases, the gap also increases, which can easily cause the hand to leave the steering wheel, reducing the usability and safety. Therefore, a steer-by-wire column is proposed to solve the above problems. Utility Model Content
