摘 要:汽车作为重要的代步工具,为人们的出行提供了极大的方便,但是,随之而来的晕车发生率呈不断上升的趋势。本文针对乘客在汽车加速、转向、制动等工况下的运动刺激和乘客自身感觉冲突等晕动症诱发因素,设计一种体感视觉综合防晕车座椅自主平衡装置。该装置依靠座椅减震器和自动控制系统保持竖直和水平方向上的体感平衡,借助头戴式显示设备使得内耳前庭感受器与视觉感受到的信息一致,保持体感与视觉的协同平衡,从而达到综合防晕车的效果。

Abstract: As an important means of transportation, cars provide great convenience for people's travel. However, the incidence of carsickness is rising. Aiming at the motion stimulus of passengers under car acceleration, steering, braking and other conditions such as motion stimulus and passengers' own feeling conflicts and other motion sickness inducing factors, this paper designed a somatosensory and visual integrated anti-sickness seat autonomous balancing device. The device relies on the seat shock absorber and the automatic control system to maintain a balance in the vertical and horizontal directions, with the help of a head-mounted display device, the vestibular receptors of the inner ear are consistent with the visually sensed information, and the synergistic balance of somatosensory and visual is maintained, so as to achieve a comprehensive anti-motion sickness effect.
Keywords: motion sickness;anti-sickness seat;damping-adjustable shock absorber;head-mounted display device
近年來,随着国家经济的发展和人民生活质量的提高,人们对出行的舒适度要求越来越高,晕车成了影响部分人群出行体验的主要因素之一[1]。晕车是晕动症的一种,晕动症是由于肌体对运动状态错误感知所导致的一系列生理反应的总和,具体表现为呕吐、冒冷汗,并伴随严重的腹泻和头昏脑胀等[2]。据统计,有晕车症状的人数占总人数的4%~10%,因此,晕车问题成为亟待研究与解决的课题。目前,解决晕车主要依靠晕车药。市面上常见的晕车药有胃复安(甲氧氯普胺)片、吗丁啉片等。但研究表明,晕车药均具有副作用,同时其适用范围也有限。
2018年,法国汽车制造商雪铁龙推出了一款防晕车眼镜架。眼镜架上有四个环,环内部蓝色液体的水平面随着汽车的行驶也会发生变化。……
