Embodiment

[0092] Such as Figure 3-5 As shown, in this embodiment, the numbers of the air pumps and the actuators are three respectively. The specific control method is as follows:

[0093] Compare the current air pressure P with the target pressure Po, and judge whether the current air bag pressure P is between 0.9-1.1 times the target pressure Po. If it is within this range, the air pump and actuator will not be turned on. If it is not within this range, then Turn on the air pump and actuator.

[0094] a. If the current airbag pressure P<0.9Po, the inflation working condition classification unit in the inflation time calculation module classifies the current airbag pressure, and calculates the time T for inflation to reach the airbag target pressure through the inflation working condition time calculation unit.

[0095] If T≤1s, on the basis of considering the delay of the system, connect 1 inflatable actuator and 1 air pump; when 1 inflatable actuator is connected, the actuator is ...

Abstract

The invention discloses an automobile seat multi-stage inflation system and a control method thereof; wherein the inflation system comprises an air bag arranged in an automobile seat; a plurality of air pumps that are respectively communicated with the air bags through air pipes; a base; a plurality of execution mechanisms which are mounted on the base and are arranged in one-to-one correspondence with the air pumps, wherein each executing mechanism comprises a fixed pulley fixedly installed on the base; a driving machine body fixedly installed on the base, and the driving machine body and the fixed pulley are arranged at intervals; a rotary valve element, wherein one end is connected to the driving machine body through a flexible hinge, and the other end of the rotary valve element extends to an air inlet of the air pipe. a memory alloy wire, wherein one end is fixedly connected to the base, and the other end of the memory alloy wire winds around the fixed pulley after being wound around the driving machine body and is fixedly connected to the rotary valve element, the two ends of the memory alloy wire being connected with a power supply; herein, the length of the memory alloy wire is changed by powering on and powering off the memory alloy wire, the rotary valve element can be driven to rotate, and the rotary valve element closes or opens an air inlet of the air pipe.

Description

technical field [0001] The invention belongs to the technical field of intelligent cockpit and vehicle body intelligentization and light weight, and in particular relates to a multi-stage inflation system for an automobile seat and a control method thereof. Background technique [0002] With the development of automobile technology, the car seat has developed from a simple part to a more complex and precise part. The functions of car seats are gradually extended, and they are not limited to providing good driving and riding posture. In high-end cars, designers have endowed car seats with massage and ventilation functions to meet the growing needs of consumers. [0003] The vast majority of traditional car seats are passive parts that need to be pulled by the user, or extremely non-intelligent parts that change the user's sitting posture with manual adjustment by the occupant, and do not involve the fields of smart cockpit and body intelligence. In recent years, designers h...
