Electric regulating switch control module of motor vehicle seat

Abstract

The invention relates to an electric regulating switch control module of a motor vehicle seat. The electric regulating switch control module comprises multiple control switches and more than one interlock switches, wherein each control switch is connected between a power supply circuit and the interlock switch of each regulating motor; the interlock switch is also connected with a vehicle body power supply and the power supply circuit of the regulating motor; therefore, when one control switch is connected with the power supply of a regulating motor, the power supply circuit of the regulatingmotor has a high level so that the interlock switch is turned on to switch the power supplies of other regulating motors; therefore, the interlocking purpose that only one regulating motor is allowedto act every time is realized so that the working current of the seat regulating system is effectively managed and the safety is improved.

Description

technical field [0001] The invention is suitable for the electric seat adjustment system of the motor vehicle, can effectively manage the working current of the seat electric adjustment system, and improves the safety of the electric seat electric system. Background technique [0002] At present, people have higher and higher requirements for the safety and ease of use of motor vehicles, and the proportion of motor vehicles equipped with electric seats is gradually increasing. General car electric seats, without position memory function, are also called pure electric seats. Its adjustment system includes: the overall horizontal direction of the seat, the overall vertical direction of the seat, the front and rear directions of the seat back, the up and down direction of the front of the seat cushion, the front and rear directions of the leg rest, the up and down and front and rear directions of the lumbar support, the front and rear directions of the shoulder rest, and the he...

AI Technical Summary

Problems solved by technology

Since all directions cannot be interlocked, multiple directions can be adjusted at the same time, that is, multiple motors can work at the same time, and the combinations between them are also diverse, which leads to potential risks in the power distribution of car electric seats: the whole seat The range of the total power consumption to be adjusted is very wide, from the normal working current of one motor (generally 1A to 6A) to simultaneous stalling of multiple motors (if 4 motors are stalled at the same time, the stalling current of each motor is 18A , it can reach 72A), and the fuse (generally 30A) equipped on the body cannot take into account the protection of the normal operation of one motor and the protection of multiple motors at the same time.

The resulting seat burning phenomenon caused by motor or switch failure occurs from time to time

[0005] In addition, since all directions cannot be interlocked, multiple directions can be adjusted at the same time. There are 6 directions on one operating handle that can be adjusted, and it is easy to misuse when adjusting.
