Document Type and Number:
WIPO Patent Application WO/2024/037284
Kind Code:
A1
Abstract:
Provided are an electric adjusting structure for a steering column, and a vehicle. The electric adjusting structure for a steering column comprises a support seat (10), a steering column (20), an electric motor (30) and a speed reduction mechanism. The steering column is slidably arranged on the support seat, and comprises a movable outer tube (21) and a steering shaft (23); the electric motor comprises a housing (31) and an output shaft (32), the housing being connected to the movable outer tube; the speed reduction mechanism comprises a worm (40) and a worm gear (50), the worm being connected to the output shaft, the worm gear meshing with the worm, and a gear (52) being coaxially arranged on a gear shaft (51) of the worm gear; a first rack (11) is fixedly arranged on the support seat, and the lengthwise direction of the first rack is arranged parallel to the axial direction of the steering shaft; a second rack (22) is fixedly arranged on the movable outer tube, the second rack and the first rack being arranged in parallel; and the gear respectively meshes with the first rack and the second rack so as to transmit the steering shaft. In the electric adjusting structure for a steering column, the speed reduction mechanism, which comprises the worm gear and the worm, is utilized to drive the gear to mesh with the first rack, which is arranged on the support seat, for transmission, thereby pushing the steering column to perform a linear reciprocating motion; and the electric motor and the steering column are coaxially arranged, such that the amount of space occupied thereby is saved on.
