Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle doors, and particularly relates to an inner door structure, a door assembly and a vehicle. Background Art

[0002] A vehicle door is a hollow structural member composed of an inner door panel and an outer door panel. A cavity is formed between the inner door panel and the outer door panel, and various components such as a motor and a reinforcing plate are integrated in the cavity. In order to reduce the weight of the vehicle door, some vehicle manufacturers use aluminum alloy vehicle doors. Although the aluminum alloy vehicle doors can effectively reduce the weight of the vehicle doors, a large number of inner panel reinforcing plates are required to increase the strength of the vehicle doors.

[0003] With the continuous progress of technology, some manufacturers have also adopted vehicle doors made of magnesium alloy. The density of the magnesium alloy material is relatively low, which greatly reduces the weight of the vehicle doors, and the magnesium alloy is easy to recycle, making it an ideal material for vehicle door lightweighting. However, due to the relatively large size of the inner door panel and the narrow window frame part, it is not easy to integrally die-cast the inner door panel of the magnesium alloy. Therefore, the existing inner door panels of magnesium alloy vehicle doors usually do not include window frames, and the window frames need to be separately manufactured and connected to the inner panel body. The inner panel body can be die-cast from magnesium alloy, but there are problems such as low connection strength and poor sealing performance at the connection between the inner panel body and the inner panel window frame. Summary of the Invention

[0004] Aiming at the technical problems of low connection strength and poor sealing performance at the connection between the inner panel body and the inner panel window frame in the prior art, the utility model provides an inner door structure, a door assembly and a vehicle.

[0005] To solve the above problems, the first embodiment of the utility model provides an inner door structure, which includes an inner door panel and a door module. The inner door panel includes an integrally formed inner window frame and an inner panel body. A window frame opening is provided on the inner window frame, and an installation opening is provided on the inner panel body. The door module is installed on the inner panel body and blocks the installation opening.

The installation opening is provided on the inner panel. The inner door structure further includes a door anti-collision beam, and opposite ends of the door anti-collision beam are respectively installed on the first boss and the second boss.

[0007] Optionally, the door anti-collision beam includes a cross plate and first side plates and second side plates connected to opposite sides of the cross plate. Opposite ends of the cross plate are respectively installed on the first boss and the second boss. A reinforcing cavity is provided between the cross plate and the inner panel.

[0008] Optionally, a third boss and a fourth boss are further provided on the inner panel body, and the third boss and the fourth boss are respectively located on opposite sides of the mounting opening;

[0009] The inner door structure further includes an outer panel reinforcement plate, and opposite ends of the outer panel reinforcement plate are respectively mounted on the third boss and the fourth boss.

[0010] Optionally, the door inner panel further includes a waistline plate disposed between the inner window frame and the inner panel body, and the inner door structure further includes a waistline reinforcement plate mounted on the waistline plate.

[0011] Optionally, the thickness of the waistline plate is 4 mm to 6 mm.

[0012] Optionally, the inner door structure further includes a sealing ring disposed around the mounting opening, and the sealing ring is sealingly connected between the door module and the inner panel body.

[0013] Optionally, the door inner panel is integrally die-cast from magnesium alloy, and the thickness of the door inner panel is 2 mm to 6 mm.

[0014] The second embodiment of the present invention provides a door assembly, including an outer door panel and the above-mentioned inner door structure, and the door inner panel is mounted on the outer door panel.
