The invention discloses an all-aluminum passenger door frame profile of a passenger car. The profile comprises a main profile body, wherein a cavity is defined by the main profile body, a first connecting plate and a second connecting plate are arranged in the main profile body in a vertical direction and connected with the main profile body, the cavity is divided into a first cavity body, a second cavity body and a third cavity body through the first connecting plate and the second connecting plate, the right side of the main profile body is connected with a first L-shaped side plate, a second L-shaped side plate and a third straight side plate; and the left side of the main profile body is connected with a third L-shaped side plate, a fourth L-shaped side plate and a second straight side plate. By changing a cavity structure and adding the connecting plates, an aluminum profile is changed into a multi-cavity aluminum profile, so the strength of the profile is effectively improved; meanwhile, the first cavity body and the third cavity body are of large chamfer structures, so bending resistance is improved; and a side plate structure is arranged, the stability of connection with other components of a vehicle door is guaranteed, and safety is improved.

    本发明公开了一种全铝客车乘客门边框型材。本发明包括型材主体,型材主体,型材主体围成型腔,型材主体内上下方向连接有连接板一和连接板二,连接板一和连接板二将型腔分为型腔一、型腔二和型腔三;所述型材主体右侧连接有L型侧板一、L型侧板二和直侧板三;所述型材主体左侧连接有L型侧板三、L型侧板四和直侧板二。本发明通过改变型腔结构,增加了连接板,变为多型腔铝材,从而有效提升了型材强度,同时本发明设计的型腔一和型腔三具有大倒角结构,增加了抗弯曲能力,并设有侧板结构,保证与车门其他构件连接的稳定性,提升安全性。
