The invention discloses a cab sealing structure and a sealing method, and belongs to the technical field of cab sealing. Polyurethane sealant is injected into a cavity of a front wall-side wall connector; the front stand column cavity is filled with a front stand column expansion rubber strip. A rear stand column cavity partition piece is installed in the rear stand column cavity, and an EVA expansion body is arranged in the rear stand column cavity partition piece. A cavity of the front wall-side wall connector is sealed through injected polyurethane sealant; a front stand column cavity is sealed through thermal expansion of a front stand column expansion rubber strip in the body-in-white electrophoresis drying process; a rear stand column cavity partition piece is installed in a rear stand column cavity, and an EVA expansion body in the rear stand column cavity partition piece is heated to be expanded and sealed in the body-in-white electrophoresis drying process. Effective plugging and sealing of a front wall-side wall connector cavity, a front stand column cavity and a rear stand column cavity are achieved, the sealing performance and corrosion resistance of a cab are effectively improved, noise and dust are prevented from invading the cab, the comfort of passengers is improved, and the fuel economy of a vehicle is improved.
本发明公开一种驾驶室密封结构及密封方法,属于驾驶室密封技术领域,前围‑侧围接头空腔内注入有聚氨酯密封胶;前立柱空腔内填充有前立柱膨胀胶条;后立柱空腔内安装有后立柱空腔隔断片,后立柱空腔隔断片内设有EVA膨胀体。对前围‑侧围接头空腔采用注入的聚氨酯密封胶密封;对前立柱空腔采用在白车身电泳烘干过程中前立柱膨胀胶条受热膨胀密封;在后立柱空腔内安装后立柱空腔隔断片,后立柱空腔隔断片内的EVA膨胀体在白车身电泳烘干过程中受热膨胀密封;实现对前围‑侧围接头空腔、前立柱空腔和后立柱空腔的有效封堵密封,有效提升驾驶室密封性和防腐蚀性能,控制噪声和灰尘侵入驾驶室,提高乘员舒适性,提高车辆燃油经济性。
