Description

Technical Field

[0001] The utility model relates to the field of bus side walls, in particular to a high-strength anti-deformation bus side wall. Background Art

[0002] The bus side wall is installed on both sides of the bus main frame. As an important part of modern bus design, it not only concerns the safety of passengers, but also symbolizes the overall performance and quality of the vehicle. In today's transportation environment that pursues safety and efficiency, a solid and stable bus side wall can not only effectively resist external impacts, but also provide additional living space for passengers in case of emergencies.

[0003] After retrieval, the lightweight bus side wall frame with the application number CN201921080444.5 includes a side frame. A vertical frame is fixedly connected between the top and the bottom of the inner cavity of the side frame, and a horizontal frame is fixedly connected between the two sides of the inner cavity of the side frame. The horizontal frame and the vertical frame are cross-connected in a cross shape, and the number of the horizontal frames is two. For this lightweight bus side wall frame, an I-shaped reinforcing member is used to reinforce the lightweight bus side wall frame, so as to improve the anti-impact ability and load-bearing capacity of the bus side wall frame. By using a plurality of trapezoidal cavities in the middle of the I-shaped reinforcing member, while not changing the strength of the I-shaped reinforcing member, the weight and material consumption of the I-shaped reinforcing member are reduced, thereby saving materials and costs and reducing the weight of the bus frame.

[0004] However, in the above technology, if a minor collision occurs, the device can play a role in anti-collision. Usually during driving, when the bus side wall is impacted at high speed, due to the insufficient stiffness of the bus side wall, it is very easy to have a situation of inward extrusion, endangering the lives of passengers. According to actual situation investigations, the impacted parts of the bus are all sunken into the vehicle body at one position. Therefore, it is necessary to improve the anti-collision ability of the bus side wall. For this reason, a high-strength anti-deformation bus side wall is proposed. Content of the Utility Model
