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

[0002] In related technologies, the stability of the door rearview mirror is crucial to the overall stability of the vehicle. Existing technologies mainly improve the rigidity of the door rearview mirror mounting point by increasing the thickness of related components. However, while this method can enhance the rigidity of the mounting point to some extent, it also significantly increases the weight of the door, affecting the vehicle's lightweight design. Furthermore, the increased door weight also impacts the vehicle's fuel economy and handling. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a door assembly that improves the mounting rigidity of the rearview mirror mounting plate and is lightweight, thus facilitating lightweight vehicle design.

[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, on which a window frame reinforcing plate, a hinge mounting plate, and a crash beam are mounted; and a rearview mirror mounting plate, which includes a panel body, a front connecting portion, and a lower connecting portion. The front connecting portion and the lower connecting portion are connected to adjacent sides of the panel body. The front connecting portion, the window frame reinforcing plate, and the hinge mounting plate are connected by at least one first fastener. The lower connecting portion is connected to the crash beam.

[0006] According to the embodiment of the present utility model, the door assembly connects the front connecting part, the window frame reinforcing plate and the hinge mounting plate by at least one first fastener, and connects the lower connecting part to the anti-collision beam. This increases the mounting points of the rearview mirror mounting plate, thereby constructing a multi-path force transmission channel, significantly improving the installation firmness and installation rigidity of the rearview mirror mounting plate. It eliminates the need to thicken the rearview mirror mounting plate, making it lightweight and beneficial to the lightweight design of the vehicle.

[0007] In some examples of this utility model, the inner door panel is further equipped with an outer panel reinforcing plate, which is connected to the panel body. This arrangement connects the rearview mirror mounting plate to the outer panel reinforcing plate, significantly improving the strength and rigidity of the mounting point of the rearview mirror mounting plate and enhancing the stability of the vehicle rearview mirror fixation.

[0008] In some examples of this utility model, the plate body has at least one connecting boss, and at least two surfaces of the connecting boss are attached to and welded to the outer plate reinforcing plate. This arrangement increases the contact area between the rearview mirror mounting plate and the outer plate reinforcing plate, significantly improving the stability and reliability of the welding between the rearview mirror mounting plate and the outer plate reinforcing plate. Furthermore, the multi-faceted contact structure of the connecting boss can transform point contact or line contact into stable surface contact, greatly enhancing the structural rigidity and deformation resistance of the rearview mirror mounting plate in multiple directions, thereby effectively suppressing problems such as blurred vision caused by vibration and shaking of the rearview mirror during operation.

[0009] In some examples of this utility model, the door assembly further includes: an outer door panel, the inner door panel, the anti-collision beam, and the outer panel reinforcement plate, all connected to the outer door panel; and at least a portion of the hinge mounting plate, the anti-collision beam, the outer panel reinforcement plate, and the window frame reinforcement plate are located between the outer door panel and the inner door panel. This arrangement allows the hinge mounting plate, anti-collision beam, outer panel reinforcement plate, and window frame reinforcement plate to be positioned between the outer door panel and the inner door panel, reducing the difficulty of arranging the door assembly and optimizing the arrangement space. Furthermore, this arrangement can distribute the load on the rearview mirror mounting plate to the hinge mounting plate, anti-collision beam, outer panel reinforcement plate, and window frame reinforcement plate, greatly improving the rigidity and strength of the rearview mirror mounting plate.

[0010] In some examples of this utility model, the door assembly further includes an outer panel support plate, which is connected to the side of the outer panel reinforcing plate away from the anti-collision beam, and is also connected to the outer door panel. This arrangement allows the upper part of the rearview mirror mounting plate to be connected to the outer panel support plate via the outer panel reinforcing plate, improving the strength and rigidity of the mounting point on the upper part of the rearview mirror mounting plate, and also contributing to improved connection rigidity in the vehicle width direction.

[0011] In some examples of this utility model, the outer door panel has an upper edging, and a portion of the outer panel support plate is embedded within the upper edging. This arrangement enables connection constraint between the outer door panel and the outer panel support plate in the vehicle height direction, greatly improving the connection strength and integrity between the outer door panel and the outer panel support plate. Furthermore, this improves the strength and rigidity of the mounting points on the upper part of the rearview mirror mounting plate, which is beneficial to improving the stability of the vehicle's rearview mirror installation.

[0012] In some examples of this utility model, the lower connecting part is connected to the anti-collision beam by at least one second fastener. This arrangement can improve the strength and rigidity of the mounting point between the lower connecting part and the anti-collision beam, improve the firmness and stability of the connection between the rearview mirror mounting plate and the anti-collision beam, facilitate installation and disassembly, improve the convenience of installation, and help improve the stability of the vehicle's rearview mirror installation.

[0013] In some examples of this utility model, the anti-collision beam includes: The beam body, the second fastener passes through the beam body and is connected to the lower connecting part, the beam body has a cavity extending along its length direction; An internal reinforcing plate is provided within the cavity and extends along the length of the beam. The internal reinforcing plate is connected to the two opposing inner walls of the cavity. This design makes the anti-collision beam structurally sound, improving its structural strength and rigidity, reducing the risk of bending deformation due to collisions, and allowing the cavity structure to absorb collision energy, thus improving vehicle collision safety. Furthermore, this design enhances the strength of the mounting point connecting the rearview mirror mounting plate to the anti-collision beam, improving the stability of the rearview mirror installation.

[0014] In some examples of this utility model, there are multiple inner beam reinforcing plates, which are arranged in parallel and spaced apart. A portion of the second fastener is located between two of the inner beam reinforcing plates. This arrangement creates a high-rigidity local support environment for the second fastener using the parallel and spaced inner beam reinforcing plates. Since the second fastener is located between two reinforcing plates, the force on the second fastener can be shared by the inner beam reinforcing plates on both sides, effectively reducing the risk of stress concentration in the anti-collision beam and significantly improving the structural strength and fatigue resistance of the connection between the anti-collision beam and the rearview mirror mounting plate.

[0015] According to another embodiment of the present invention, a vehicle including the door assembly of the above embodiment can increase the mounting points of the rearview mirror mounting plate by connecting the front connecting part, the window frame reinforcing plate and the hinge mounting plate through at least one first fastener, and connecting the lower connecting part to the anti-collision beam. This creates a multi-path force transmission channel, significantly improving the installation firmness and installation rigidity of the rearview mirror mounting plate. It eliminates the need to thicken the rearview mirror mounting plate, making it lightweight and beneficial for the lightweight design of the vehicle.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The stability of the rearview mirror is crucial to the overall stability of the vehicle. Existing technologies mainly improve the rigidity of the rearview mirror mounting point by increasing the thickness of related components. However, while this method can enhance the rigidity of the mounting point to some extent, it also significantly increases the weight of the door, affecting the vehicle's lightweight design. Furthermore, the increased door weight also impacts the vehicle's fuel economy and handling. This application increases the mounting points of the rearview mirror mounting plate 30 by connecting the front connecting part 315, the window frame reinforcing plate 40, and the hinge mounting plate 50 through at least one first fastener 91, and connecting the lower connecting part 316 to the anti-collision beam 60. This creates a multi-path force transmission channel, significantly improving the installation firmness and rigidity of the rearview mirror mounting plate 30. It eliminates the need to thicken the rearview mirror mounting plate 30, resulting in a lighter weight that is beneficial for the vehicle's lightweight design.

In some embodiments of this application, the door inner panel 10 and the window frame reinforcing plate 40 are connected by welding and bolting. The door inner panel 10 can be connected to the hinge mounting plate 50 by, but is not limited to, welding or bolting. In some embodiments of this application, the door inner panel 10 and the hinge mounting plate 50 are connected by welding. The door inner panel 10 can be connected to the anti-collision beam 60 by, but is not limited to, welding or bolting. In some embodiments of this application, the door inner panel 10 and the anti-collision beam 60 are connected by bolting. In some embodiments of this application, overlapping the front and rear ends of the anti-collision beam 60 with the door inner panel 10 can significantly increase the bending stiffness in the Y direction.

[0025] The rearview mirror mounting plate 30 includes a plate body 31, a front connecting part 315, and a lower connecting part 316. The front connecting part 315 and the lower connecting part 316 are connected to adjacent sides of the plate body 31.

Along the height direction of the vehicle, the lower connecting part 316 is located below the plate body 31 and adjacent to the plate body 31. As some embodiments of this application, the rearview mirror mounting plate 30 is constructed as an integrally molded part.

[0026] The front connecting part 315, the window frame reinforcing plate 40, and the hinge mounting plate 50 are connected by at least one first fastener 91. That is, the front connecting part 315, the window frame reinforcing plate 40, and the hinge mounting plate 50 are connected by one first fastener 91, or the front connecting part 315, the window frame reinforcing plate 40, and the hinge mounting plate 50 are connected by multiple first fasteners 91.

[0030] As some embodiments of this application, such as Figure 5 As shown, the front connecting part 315 extends 30mm along the length of the vehicle and is connected by three bolts, which makes the connection strength of the front connecting part 315, the window frame reinforcing plate 40 and the hinge mounting plate 50 significantly higher than the weld strength by more than 10 times.

[0031] It should be noted that the door assembly 100 of this application can significantly improve the structural strength of the front connecting part 315 of the rearview mirror mounting plate 30 by connecting the front connecting part 315 of the rearview mirror mounting plate 30 to the window frame reinforcing plate 40 and the hinge mounting plate 50. By connecting the lower connecting part 316 of the rearview mirror mounting plate 30 to the anti-collision beam 60, the strength, rigidity and durability of the mounting point of the rearview mirror mounting plate 30 can be significantly improved, thereby improving the stability of the vehicle rearview mirror fixing.

[0032] Moreover, this design eliminates the need to thicken the rearview mirror mounting plate 30, resulting in a lighter weight and significantly improved vehicle fuel economy and handling performance.

[0033] Therefore, by connecting the front connecting part 315, the window frame reinforcing plate 40, and the hinge mounting plate 50 with at least one first fastener 91, and connecting the lower connecting part 316 with the anti-collision beam 60, the number of mounting points of the rearview mirror mounting plate 30 can be increased, thereby constructing a multi-path force transmission channel, significantly improving the installation firmness and installation rigidity of the rearview mirror mounting plate 30, eliminating the need to thicken the rearview mirror mounting plate 30, making it lightweight and beneficial to the lightweight design of the vehicle.

As some embodiments of this application, the connecting boss 311 is formed with a first surface 312, a second surface 313 and a third surface 314, all of which are attached to and welded to the outer plate reinforcing plate 70.

[0041] This design increases the contact area between the rearview mirror mounting plate 30 and the outer panel reinforcing plate 70, significantly improving the stability and reliability of the welding between the rearview mirror mounting plate 30 and the outer panel reinforcing plate 70. Furthermore, the multi-faceted fit structure of the connecting boss 311 can transform point contact or line contact into stable surface contact, greatly enhancing the structural rigidity and deformation resistance of the rearview mirror mounting plate 30 in the Y and Z directions. This effectively suppresses problems such as blurred vision caused by vibration and shaking of the rearview mirror during operation.

[0053] In some embodiments of this utility model, such as Figure 6 As shown, the outer door panel 20 has an upper edging 93, and a portion of the outer panel support plate 80 is embedded in the upper edging 93.

[0054] Along the height direction of the vehicle, the outer door panel 20 has an upper edging 93, and a portion of the outer panel support plate 80 is embedded in the upper edging 93 to connect the outer panel support plate 80 to the outer door panel 20. As some embodiments of this application, a portion of the outer panel support plate 80 is embedded in the upper edging 93 and bonded to the upper edging 93.

[0055] This configuration enables the connection constraint between the outer door panel 20 and the outer panel support plate 80 in the vehicle height direction, greatly improving the connection strength and integrity between the outer door panel 20 and the outer panel support plate 80. Furthermore, this configuration can improve the strength and rigidity of the mounting point on the upper part of the rearview mirror mounting plate 30, which is beneficial to improving the stability of the vehicle's rearview mirror installation.

[0056] In some embodiments of this utility model, such as Figure 4 As shown, the lower connecting part 316 is connected to the anti-collision beam 60 by at least one second fastener 92.

[0057] In other words, the lower connecting part 316 is connected to the anti-collision beam 60 by one second fastener 92, or the lower connecting part 316 is connected to the anti-collision beam 60 by multiple second fasteners 92. As some embodiments of this application, the lower connecting part 316 is connected to the anti-collision beam 60 by three second fasteners 92.

The beam internal reinforcing plate 62 is connected to the two cavity inner walls 65 opposite to the cavity 63.

[0060] As some embodiments of this application, the beam 61 has a mating hole 94 that mates with the second fastener 92. The second fastener 92 can pass through the mating hole 94 and be connected to the lower connecting part 316. The beam 61 has a cavity 63 that can extend along the length direction of the beam 61. The anti-collision beam 60 also includes an inner beam reinforcing plate 62. The inner beam reinforcing plate 62 is disposed in the cavity 63 and connected to two inner walls 65 opposite to the cavity 63. The inner beam reinforcing plate 62 extends along the length direction of the beam 61. There are multiple inner beam reinforcing plates 62.

[0063] As some embodiments of this application, there are two beam internal reinforcing plates 62, which are arranged parallel to each other along the width direction of the beam body 61 to divide the cavity 63 into three sub-cavities 64. The second fastener 92 can be inserted into the middle sub-cavity so that a part of the second fastener 92 is located between the two beam internal reinforcing plates 62.

[0064] This arrangement creates a high-rigidity local support environment for the second fastener 92 by utilizing the parallel-spaced beam internal reinforcing plates 62.
