Description

Technical Field

[0001] This utility model relates to the field of vehicle door technology, and in particular to a vehicle door assembly and a vehicle. Background Technology

[0002] In related technologies, for irregularly shaped car doors such as butterfly doors, dispersed reinforcing components are often used for localized reinforcement to increase the rigidity of the door and window frames. However, these reinforcing components lack overall connectivity and are scattered, resulting in poor coordination between them and failing to form a unified load-bearing structure. Under complex stress conditions, localized stress concentration may occur, affecting the overall strength and rigidity of the door structure. Furthermore, the extensive use of dispersed reinforcing components increases vehicle weight, leading to higher costs and hindering lightweight vehicle design. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a door assembly with high structural strength, high rigidity, and low weight, which is beneficial to the lightweight design of vehicles.

[0004] This utility model further proposes a vehicle.

[0005] According to an embodiment of the present utility model, a door assembly includes: an inner door panel, the inner door panel including a door panel portion and a top panel portion, the door panel portion having a window clearance hole, and the top panel portion being connected to the door panel portion at an angle; and a reinforcing member, the reinforcing member including an integrally connected window reinforcing frame and a door top reinforcing frame, the window reinforcing frame being disposed around the outside of the window clearance hole and connected to the door panel portion, and the door top reinforcing frame being connected to the top panel portion.

[0006] According to the embodiments of the present invention, the door assembly is constructed by having a window reinforcing frame wrapped around the outside of the window clearance hole and connected to the door panel, and a door top reinforcing frame connected to the top panel, and the window reinforcing frame and the door top reinforcing frame integrally connected. This significantly improves the overall structural strength, rigidity, and torsional performance of the door assembly, reduces the risk of local stress concentration in the door assembly, and reduces the weight of the door assembly, resulting in low cost and facilitating lightweight vehicle design.

[0007] In some examples of this utility model, the window reinforcement frame has an inner window flange near the window clearance hole and an outer window flange away from the window clearance hole. Both the inner and outer window flanges are fitted to the door panel and connected at the fitting point by welding or fasteners. This arrangement improves the connection strength between the window reinforcement frame and the door panel, thereby improving the connection strength between the inner door panel and the reinforcement, which is beneficial to improving the structural strength and rigidity of the door assembly.

[0008] In some examples of this utility model, the window reinforcing frame further includes a window connecting plate, which is connected between the inner edge and the outer edge of the window. At least a portion of the window connecting plate is separated from the door panel, so that the window reinforcing frame and the door panel together define a first cavity. This arrangement can significantly improve the structural strength of the door panel, increase the overall torsional strength of the door assembly, and the window connecting plate can provide mounting points for other components of the door assembly, which is beneficial to improving the reliability of the door assembly.

[0009] In some examples of this utility model, the window connecting plate includes at least one window reinforcement portion, which is bent toward or away from the door panel portion. This arrangement can significantly improve the structural strength of the reinforcement, the structural strength and bending resistance of the inner door panel, and the overall bending resistance of the inner door panel.

[0010] In some examples of this utility model, the door assembly further includes a hinge reinforcement plate, at least a portion of which is sandwiched between the door panel and the window reinforcement frame. The door panel, the hinge reinforcement plate, and the window reinforcement frame are connected by fasteners. This arrangement improves the connection strength between the door panel, the hinge reinforcement plate, and the window reinforcement frame, thereby enhancing the structural strength and rigidity of the door assembly.

[0011] In some examples of this utility model, the door top reinforcing frame extends along the edge of the portion separating the top plate and the door panel, and both ends of the door top reinforcing frame are connected to the window reinforcing frame to form weight-reduction holes. This arrangement can improve the structural strength and rigidity of the top plate, and can make the door panel and the top plate form a whole, improving the overall connectivity. Furthermore, by forming closed weight-reduction holes in the door top reinforcing frame, the overall weight of the reinforcing component can be reduced, which is beneficial for the lightweight design of the vehicle.

[0012] In some examples of this utility model, the door top reinforcing frame has an inner door top flange near the weight-reducing hole and an outer door top flange away from the weight-reducing hole, both of which are fitted and connected to the top plate portion. This arrangement can improve the connection strength between the door top reinforcing frame and the top plate portion, thereby improving the connection strength between the inner door panel and the reinforcing member, which is beneficial to improving the structural strength and rigidity of the door assembly.

[0013] In some embodiments of this utility model, the door top reinforcing frame further includes a door top connecting plate, which is connected between the inner door top flange and the outer door top flange. At least a portion of the door top connecting plate is separated from the top plate portion, so that the door top reinforcing frame and the top plate portion together define a second cavity. This arrangement can significantly improve the structural strength and rigidity of the top plate portion, improve the overall torsional strength of the door assembly, and help improve the reliability of the door assembly.

[0014] In some embodiments of this utility model, the door top connecting plate includes at least one door top reinforcing portion, which is bent toward or away from the top plate portion. This arrangement significantly improves the structural strength of the door top reinforcing frame, thereby improving the structural strength of the inner door panel and enhancing its overall bending resistance. According to another embodiment of the present invention, a vehicle includes the aforementioned door assembly. By having a window reinforcement frame surrounding the outside of the window clearance hole and connected to the door panel, and a door top reinforcement frame connected to the top panel, and by making the window reinforcement frame and the door top reinforcement frame integrally connected, the overall structural strength, rigidity, and torsional performance of the door assembly can be significantly improved, the risk of local stress concentration in the door assembly can be reduced, and the weight of the door assembly can be reduced, resulting in low cost and facilitating lightweight vehicle design.

[0019] In related technologies, dispersed reinforcing components are often used for localized reinforcement to increase the rigidity of door and window frames. However, these reinforcing components lack overall connectivity and are scattered, resulting in poor coordination and an inability to form a unified load-bearing structure. Under complex stress conditions, localized stress concentration may occur, affecting the overall strength and rigidity of the door structure.
