[0023] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and clear, and to fully convey the concept of the present application to those skilled in the art.

[0024] In addition, for any single technical feature described or implied in the embodiments mentioned in this document, or any single technical feature displayed or implied in the accompanying drawings, it is easy for those skilled in the art to continue to make appropriate combinations or deletions between these technical features (or their equivalents), thereby obtaining more other embodiments of the present application that may not be directly mentioned in this document, and these embodiments do not deviate from the scope of the technical idea of ​​the present application.

[0025] Figure 1 is a schematic diagram of a door inner panel 100 according to an embodiment of the present application, Figure 2 Shown from the side Figure 1 The enlarged view of A in the figure. The door inner panel 100 is used in a vehicle door assembly, and includes a door inner panel body 110 and a side wall 120 that is bent and extended from the edge of the door inner panel body 110 toward the door outer panel (not shown) of the door assembly. The door inner panel 100 can be formed, for example, by a stamping process, and the draft angle of the side wall 120 is about 3 to 5 degrees, that is, when the side wall 120 is assembled on the vehicle, it forms an inclination angle of about 3 to 5 degrees with the lateral direction of the vehicle (that is, the left and right direction of the vehicle, the Y direction in the vehicle coordinate system). Figure 2 It can be seen that the side wall 120 is provided with a door lock assembly hole 121, which may specifically include a door lock installation hole 1211 configured to accommodate a door lock body and a plurality of (e.g., 3) door lock fastening holes 1212 configured to install a door lock fastener to fix the door lock. The partial opening of the door lock installation hole 1211 shown in the figure also extends to the door inner panel body 110. The side wall 120 is configured with a recessed portion 122 recessed toward the interior of the door assembly. When stacked for storage or transportation, the recessed portion 122 of the door inner panel 100 abuts against the side of the door inner panel 100 stacked thereon that faces the interior of the door assembly (i.e., the side facing the door outer panel, i.e., the side facing the door inner panel). Figure 1 The door inner panel 100 is spaced apart from the other door inner panel 100 to prevent burrs on the punching edge of one door inner panel 100 (e.g., burrs on the edge of the door lock assembly hole 121) stacked adjacent to each other from scratching the surface of the other door inner panel 100 during transportation or storage.

[0026] Under this arrangement, the door inner panel 100 mentioned in this article realizes the staggered stacking of multiple door inner panels 100 on the rack by setting the recessed portion 122, thereby avoiding friction scratches on the surface of the door inner panel 100 caused by transportation shaking and scratch defects during the use of the door inner panel 100, reducing surface repair work, improving the manufacturing efficiency of the door inner panel 100, optimizing the surface quality of the door inner panel 100, and thus ensuring the aesthetics of the vehicle.

[0027] The following will introduce further specific implementation or refinement and improvement process of the vehicle door inner panel through exemplary descriptions, so as to further improve its working efficiency, reliability or for other improvement considerations.

[0028] Also like Figure 2 As shown, the side wall 120 is configured with two or more sealing strip assembly holes 123, and four sealing strip assembly holes 123 are shown in the figure. The two or more sealing strip assembly holes 123 are arranged in sequence along a preset extension path that matches the extension direction of the door sealing strip of the door assembly, so as to be used to install the door sealing strip. The recessed portion 122 is configured to be arranged along the preset extension path, so that it can be covered by the door sealing strip and does not affect the overall appearance of the door assembly. Specifically, the recessed portion 122 is arranged at the interval between the two or more sealing strip assembly holes 123. In a preferred embodiment, the side wall 120 is configured with two recessed portions 122 arranged at intervals, so that the stacking spacing between the door inner panels 100 is controllable and stable, without a part being separated and another part still close. In an optional embodiment, the position or number of the recessed portions 122 can be appropriately modified according to the extension direction of the sealing strip and the position and size of the door lock assembly hole 121.

[0029] Figure 3 yes Figure 2 The enlarged view of point B in the middle. Figure 4 yes Figure 3 Cross-sectional view at CC. It can be seen that the recessed portion 122 can be configured as a spherical cap-shaped recessed pit, the radius R1 of the spherical cap is about 6mm to 10mm, the recessed distance H (i.e., the height of the spherical cap) of the recessed portion 122 in the direction perpendicular to the surface of the side wall 120 is about 0.5mm to 1mm, the diameter D of the outer circumference of the recessed pit can be about 10mm, and the edge of the recessed pit can be designed to be a smooth transition, and the radius R2 of the chamfer is about 3mm to 5mm. The stacking spacing of the door inner panel 100 is related to the recessed spacing H. In a specific embodiment, the appropriate recessed spacing H and other related geometric parameters can be designed according to the stacking space requirements and the specific size and shape of the door inner panel 100.

[0030] Figure 5 There are two Figure 12 is a cross-sectional view of the door inner panels 100 stacked together, wherein the cut plane passes through a recessed portion 122 . Figure 6 There are two Figure 1 12 is a cross-sectional view of the door inner panels 100 stacked together, wherein the cut surface passes through a door lock fastening hole 1212. Figure 5 It can be seen that due to the presence of the recessed portion 122 and the inclination angle of the side wall 120 itself, when the right door inner panel 100 is stacked toward the left door inner panel 100 approximately along the direction of arrow E, the recessed portion 122 of the left door inner panel 100 abuts against the side wall 120 of the right door inner panel 100, so that a gap is formed between the two door inner panels 100 without being tightly attached. Figure 6 It can be seen that due to the interval and stacking between the two door inner panels 100, there is a gap between the punched hole on the door inner panel 100 (such as the door lock fastening hole 1212) and the surface of the other door inner panel 100 (such as the side wall 120), so that the edge of the punched hole will not scratch the surface of the other door inner panel 100 during transportation or the picking and placing of the door inner panel 100.

[0031] The above examples mainly illustrate the door inner panel, door assembly and vehicle of the present application. Although only some of the embodiments of the present application are described, it should be understood by those skilled in the art that the present application can be implemented in many other forms without departing from its subject matter and scope. Therefore, the examples and embodiments shown are regarded as illustrative rather than restrictive, and the present application may cover various modifications and replacements without departing from the spirit and scope of the technical solution of the present application.
