摘　　要：目的 在汽车内室中,作为传统乘员约束系统的安全带与安全气囊已经存在相当长的时间,虽然对乘员的碰撞安全起到了积极的保护作用,但存在若干弊端,尤其在某些特殊工况下缺乏有效保护,会产生潜在损伤。在不能充分满足未来自动驾驶汽车需求的情境下,因乘员的各种姿态和多种活动,以及对乘员保护的全面性和有效性的要求,有必要在内室设计中对乘员保护方式进行完善和创新。方法 在对传统内室壁面和乘员约束系统进行文献综述和全面审视的基础上,从内室结构原型创新的角度,提出基于充气式壁面结构的内室设计新概念,并对这一新概念进行了创新点的梳理,以及初步的可行性分析论证,并进一步进行了意向性的内室概念呈现及后续的研究规划。结果 初步仿真分析表明,碰撞过程中充气式壁面结构对应的头部损伤指标满足国际通用标准,对乘员安全保护的机制来说是可行的。基于充气式壁面结构的汽车内室还将从材料层面实现汽车内室绿色环保、助推汽车轻量化、营造汽车内室新的视觉景观。结论 基于充气式壁面结构的汽车内室新概念是对传统汽车内室壁面结构的变革性创新,在部分保留传统约束系统的基础上,形成开拓性的乘员安全保护机制,是汽车内室工业设计在形态学上的突破性尝试。基于工程科学与设计艺术的结合,这一探索将为未来汽车内室设计提供新的思路和参考。As a traditional occupant restraint system within a vehicle,safety belts and airbags have been adopted for a long time.Although they have played a positive role in protecting the occupant's safety in crash accidents,there are some disadvantages,especially the lack of effective protection under some special working conditions,which will lead to po-tential damage.In case of that the demand for autonomous vehicles cannot be fully met in the future,it is necessary to improve and innovate in the occupant protection mode in the interior design because of the various postures and activities of the occupants and the requirements for the comprehensiveness and effectiveness of occupant protection.Based on a re-view of the traditional vehicle interior wall and the occupant restraint system,a new concept of vehicle interior design based on inflatable wall structure was proposed from the perspective of prototype innovation in interior structure.Then,the innovation of this new concept was sorted out,the preliminary feasibility analysis and demonstration were carried out,the intentional concept of interior was further presented and the follow-up research plan was made.The preliminary simulation analysis indicated that the Head Impact Criteria corresponding to the inflatable wall structure met the interna-tional common standards during the collision,which was feasible for the protection mechanism of occupant safety.The vehicle interior based on the inflatable wall structure also realized the environmental protection of vehicle interior from the material level,promoted the lightweight of the vehicle and created a new visual landscape of the vehicle interior.The new concept of vehicle interior based on inflatable wall structure is a revolutionary innovation of traditional vehicle inte-rior wall structure.On the basis of partially retaining the traditional restraint system,a pioneering occupant safety protec-tion mechanism is formed,which is a morphological breakthrough attempt of industrial design of vehicle interior.Com-bining en
