A multifunctional electric control unlocking system and a seat

Abstract

The invention provides a multifunctional electronically controlled unlocking system and a seat. The system comprises at least one electric magnet device and a driving source, wherein the electric magnet device comprises a connecting plate, a core shaft with a core shaft body and a flange radially extends from the core shaft body, first bearings sleeved between the core shaft body and the connecting plate, spring pieces and friction pieces, and coils arranged on the outer side in the radial direction of the core shaft body. The core shaft body is sequentially sleeved with the spring pieces andthe friction pieces, the outer rings of the spring pieces are fixedly connected with the outer rings of the friction pieces, the inner rings of the spring pieces are connected with the inner ring of the connecting plate, and the middle parts of the spring pieces, between the inner rings and the outer rings, keep free states. The driving source is connected with the free end of the core shaft body,wherein certain gaps are maintained between the friction pieces and the flange of the core shaft when the coils are in non-electrified states. The invention provides the multifunctional electronically controlled unlocking system which has significant advantages over the prior art and a seat with the multifunctional electronically controlled unlocking system.

Description

technical field [0001] The present invention relates to an unlocking system, more particularly to a multi-functional electric control unlocking system and a seat. Background technique [0002] At present, in the field of automobiles, the front and rear positions, high and low positions, and backrest inclination angle of the seat are usually adjusted in a combination of manual and electric methods. Among them, the electric adjustment mechanism is controlled by a button switch to control the motor to drive the mechanism. It is related to the speed of the motor and the transmission ratio; while the adjustment of the manual slideway and recliner is only to manually unlock the internal mechanism, so that the mechanism is in an unlocked state, and the speed of the mechanism can be freely adjusted at any speed through the application of human force. [0003] However, this adjustment method has the following obvious defects for the seat adjustment of the middle row and the rear row....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multifunctional electric control unlocking system and a seat, so as to solve the problems in the prior art that the unlocking mechanism is bulky and requires a large unlocking force during the seat adjustment process, and the electric angle adjustment is difficult to meet the output force requirement, and manual Difficult to adjust and inconvenient to use
