Vehicle seat and electric rotation device thereof

Abstract

The invention discloses a vehicle seat and an electric rotation device thereof, the electric rotation device comprises a base and a rotary plate and further comprises a driving part, wherein the driving part comprises a motor and an angle adjuster which comprises a rotation shaft, a driving wheel, an inner toothed plate and an outer toothed plate, the inner toothed plate and the outer toothed plate are mutually meshed, and the rotation shaft is connected with the output shaft of the motor and is connected with the outer toothed plate by the driving wheel so that the outer toothed plate can rotate relative to the inner toothed plate; the inner toothed plate is connected with the base, and the outer toothed plate is connected with the rotary table. Accordion to the vehicle seat and an electric rotation device thereof, the motor drives the angle adjuster so that the rotary table can rotate relative to the base, the manpower is saved, the adjustment is convenient, and the vehicle seat hasexcellent comfort. The angle adjuster has the advantage of compact structure on the basis of realizing transmission, stepless regulation of the electric rotation device can be realized, and the rotarytable can rotate to any position relative to the base and is locked when adjusted to the position. The angle adjuster can bear the external force from all direction of the electric rotation device, so that the strength of the electric rotation device can be improved.

Description

technical field

[0001] The invention relates to the technical field of vehicle seats, in particular to a vehicle seat and an electric rotating device thereof. Background technique

[0002] A vehicle seat includes a seat and a seat back. Usually, the seat back can be adjusted forward and backward. At present, the seat of some vehicles can also be rotated to adjust the angle at which passengers sit. However, the adjustment of these vehicle seat seats is all realized by manual adjustment, that is, the passenger needs to manually drive the rotating seat. The above-mentioned adjustment process consumes manpower and is inconvenient to adjust, resulting in lower comfort for passengers.

[0003] In view of this, how to provide a rotation adjustment device for a vehicle seat, which does not need to be driven by manpower when the seat rotates, thereby saving manpower and improving comfort, is a technical problem to be solved urgently by those skilled in the art.
