L-shaped recess portion, the glass different for adhesive thickness, window frame, side skin or different materials inside gadget, it is ensured that it is viscous
Rear outer surface is connect in same plane, so that it is guaranteed that the aesthetics of car.
Referring to figs. 1 to Figure 14, it should be noted that aluminum profile 1, aluminum profile 2 120, aluminum profile 3 130 and aluminium profiles
Material 4 210 be applied to coach body structure when, other than scheme provided in this embodiment, can also according to actual design need and
Topology requirement is flexibly applied to the different parts or different types of bus body of bus body.Connector 1, connector
2 23 and the structural strength of connector 3 24 successively decreased by Qiang Zhiruo, connector 1 is mainly used in higher to Structural strength calls
Aluminum profile between connection, connector 2 23 and connector 3 24 are mainly used in the lower aluminum profile of Structural strength calls
Between connection.Therefore when connector 1, connector 2 23 and connector 3 24 are applied to coach body structure, in addition to this reality
Outside the assembling scheme that example offer is provided, can also according to specific aluminium profile structure and assembled position to specific requirements of structural strength etc. into
Row selection assembly.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model
For.
