[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0050] This embodiment provides a door inner panel structure that simplifies the structure, improves weight reduction, and enhances the protection of the upper parts of the door assembly. For example... Figure 1 and Figure 2 As shown, the door inner panel structure includes a door inner panel assembly 10, a first crossbeam 20, a second crossbeam 30, and a reinforcing longitudinal beam 40. The door inner panel assembly 10 includes a first side 11 and a second side 12 opposite to each other in the front-rear direction. The first crossbeam 20 is located on the outer side of the door inner panel assembly 10 (the outer side refers to the side closer to the screen in the figure, that is, the side where the outer panel of the car door is set in the figure, and the side away from the screen is the inner side) and one end is connected to the first side 11, and the other end is connected to the second side 12. The second crossbeam 30 is located on the outer side of the door inner panel assembly 10 and below the first crossbeam 20. One end of the second crossbeam 30 is connected to the first side 11, and the other end is connected to the second side 12. One end of the reinforcing longitudinal beam 40 is connected to the first crossbeam 20, and the other end is connected to the top side of the door inner panel assembly 10. The top side of the door inner panel assembly 10 is the bottom edge of the window frame 200. The first crossbeam 20, the second crossbeam 30, and the reinforcing longitudinal beam 40 are all made by stamping.

[0051] The aforementioned door inner panel structure, by simultaneously setting a first crossbeam 20, a second crossbeam 30, and a reinforcing longitudinal beam 40 on the outer side of the door inner panel assembly 10, provides impact protection for the occupant's legs and hips in conjunction with the first side 11 and the second side 12. The projection of the area formed by the top side of the door inner panel assembly 10, the first crossbeam 20, and the reinforcing longitudinal beam 40 in conjunction with the first side 11 and the second side 12 in the inward and outward directions can cover the occupant's waist and above. The setting of the reinforcing longitudinal beam 40 integrates this area, improving its impact resistance and providing effective protection for these positions. The second crossbeam 30 and the lower part of the door inner panel assembly 10 provide protection for the occupant's legs below. Thus, the protection for the occupant is more comprehensive. At the same time, the first crossbeam 20, the second crossbeam 30, and the reinforcing longitudinal beam 40 are all made by stamping, which is simple and easy to manufacture. Compared with steel pipe reinforcement, it is lighter and improves the lightweight level of the door inner panel structure.

[0052] It should be noted that the figure in this embodiment shows the front door inner panel assembly, with the first side 11 being the front side and the second side 13 being the rear side. In another embodiment, it can also be the rear door inner panel assembly, which is not limited here.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, the inner door panel assembly 10 includes an inner door panel 13 and a window frame reinforcing plate 14. The inner door panel 13 is a box-shaped structure with an outward opening and has a first side 11 and a second side 12. The top side of the inner door panel 13 is connected to the window frame 200. One end of the window frame reinforcing plate 14 is connected to the first side 11, and the other end is connected to the second side 12. The window frame reinforcing plate 14 is located above the first crossbeam 20, and one end of the reinforcing longitudinal beam 40 is connected to the window frame reinforcing plate 14. Through the above arrangement, the window frame reinforcing plate 14 can be reinforced at the bottom edge of the window frame 200, providing better support for the outer panel of the window frame 200, while providing a sufficiently large welding plane for welding the reinforcing longitudinal beam 40.

[0054] In addition, in this embodiment, the window frame 200 (inner panel) is connected to the door inner panel 13, that is, it is formed by stamping from a single sheet of material. In other embodiments, the window frame 200 and the door inner panel 13 can also be welded together after being formed separately, which is not limited here.

[0055] Optionally, such as Figure 1 and Figure 2As shown, the inner door panel assembly 10 also includes a support member 15, which is located at the corner of the inner door panel 13. The support member 15 includes a supporting portion 151, a first connecting portion 152, a second connecting portion 153, and a supporting portion 154. The supporting portion 151 is consistent with the profile of a portion of the window frame reinforcing plate 14 and is located on the inner side of the window frame reinforcing plate 14. The first connecting portion 152 is connected to the top side of the supporting portion 151 and is connected to the top side of the inner door panel 13. The second connecting portion 153 is connected to the front side of the supporting portion 151 and is connected to the front side of the inner door panel 13. The supporting portion 154 is connected to the supporting portion 151 and extends toward the inner side of the supporting portion 154. One end of the supporting portion 154 away from the supporting portion 151 is connected to the outer side of the inner door panel 13. It is understandable that the partial window frame 200 reinforcement is a functional surface. If this area is not treated, its inner side will be suspended. However, by setting the support member 15, this area is supported, which improves the strength of the functional surface and makes it less likely to collapse.

[0056] Optionally, such as Figure 2 As shown, the window frame reinforcing plate 14 forms two connected first welding planes 141 and 142 with a height difference (in the inward and outward directions). The first welding plane 141 is welded to the support portion 151 by at least two weld points, and the second welding plane 142 is welded to the support portion 151 by at least two weld points. In other words, because the support portion 151 conforms to the surface at that location, the connection stability is improved after the two are fitted together and welded through the first welding plane 141 and the second welding plane 142. Of course, the corresponding positions of the first connecting portion 152, the second connecting portion 153, and the first side edge 11 are also fixed by welding.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the inner door panel assembly 10 also includes a hinge reinforcement plate 16, which covers at least a portion of the side of the inner door panel 13 on the side where the hinge is mounted. One end of the first crossbeam 20 is connected to the hinge reinforcement plate 16, and one end of the second crossbeam 30 is connected to the hinge reinforcement plate 16. In this embodiment, the hinge reinforcement plate 16 is welded to the outer side of the first side 11, one end of the first crossbeam 20 is welded to the hinge reinforcement plate 16, and one end of the second crossbeam 30 is welded to the hinge reinforcement plate 16. This improves the strength of the plate at the hinge location while providing sufficient welding area for the welding of the first crossbeam 20 and the second crossbeam 30.

[0058] Optionally, such as Figure 2 As shown, the first connecting part 152 is welded to the outside of the hinge reinforcing plate 16, that is, the first connecting part 152 is welded to the first side through the hinge reinforcing plate 16.

[0059] Optionally, such as Figure 1 and Figure 2As shown, the inner door panel assembly 10 also includes a latch reinforcement plate 17, which and the hinge reinforcement plate 16 are respectively disposed on opposite sides of the inner door panel 13, and at least a portion of the other end of the first crossbeam 20 is connected to the latch reinforcement plate 17.

[0060] Furthermore, one end of a portion of the first crossbeam 20 is connected to the latch reinforcement plate 17, and another end of a portion of the first crossbeam 20 is connected to the corresponding side of the inner door panel 13. That is to say, for the other end of the first crossbeam 20, the upper smooth surface is welded to the latch reinforcement plate 17, and the lower smooth surface is connected to the second side 12. The flange edge of the hinge reinforcement plate 16 also provides a welding position for a portion of the other end of the first crossbeam 20.

[0061] It should be noted that the first side 11 and the second side 12 are general terms referring to positions. For example, in this embodiment, the connection position between the rear end of the second crossbeam 30 and the second side 12 can be selected by those skilled in the art within a certain width range in the front and rear direction of the second side 12 for welding.

[0062] Optionally, such as Figure 1 As shown, the connection position of the first crossbeam 20 and the first side 11 is above the middle position of the first side 11, so that the position of the first crossbeam 20 covers the position above the waist of the occupant. The connection position of the second crossbeam 30 and the first side 11 is below the middle position of the first side 11, so that the position below the feet of the occupant can be protected. The reasonable position setting ensures that the crossbeam spacing on the outer side of the inner door panel assembly 10 is reasonable and the strength is uniform.

[0063] This embodiment also provides a door assembly, which includes the aforementioned inner door panel structure and an outer door panel, with the outer door panel connected to the inner side of the inner door panel structure. By employing the aforementioned inner door panel structure, this door assembly has a simpler structure, lighter overall weight, and more comprehensive protection.

[0064] This embodiment provides a vehicle including a frame and the aforementioned door assembly. The frame forms at least one door mounting position, and each door mounting position is connected to a door assembly. By adopting the aforementioned door assembly, the vehicle achieves a higher level of weight reduction, and the door assembly provides more comprehensive and reliable protection for passengers or the driver in the event of an external impact.

[0065] It should be noted that the door inner panel structure or door assembly provided in this embodiment can be any of the left front door, left rear door, right front door or right rear door, as well as other types of door inner panel structures such as sliding doors, which are not limited here.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
