[0027] Referring to Figures 1-4 The door frame inner plate structure of the embodiment of the present application comprises a door frame sheet metal part 2 and a bracket 3, the bracket 3 is arranged between a door frame inner panel 1 and the door frame sheet metal part 2, the door frame sheet metal part 2 has a local plane feature 2111, the bracket 3 comprises a fixed plate 31 and a positioning plate 32 connected at an angle, the fixed plate 31 is attached to and connected with the local plane feature 2111, and the positioning plate 32 is arranged to be connected with the door frame inner panel 1, wherein the size of the fixed plate 31 in at least one dimension direction is smaller than the size of the local plane feature 2111.
[0028] The door frame inner plate structure provided by the embodiment, wherein the support 3 comprises a fixed plate 31 and a positioning plate 32 which are connected at an angle, the fixed plate 31 is connected, for example, welded, with the door frame sheet metal part 2, and the positioning plate 32 is arranged at an angle with the fixed plate 31 and is used to be connected with the door frame inner trim plate 1 to at least support the door frame inner trim plate 1, thereby improving the strength of the door frame side wall at a certain local position, for example, the positioning plate 32 is used to abut against the door sill part (door sill inner trim plate) of the door frame inner trim plate 1, so as to improve the strength of the door frame at the door sill to prevent the door sill from being stepped and deformed.
[0029] When the fixed plate 31 of the support 3 is welded with the door frame sheet metal part 2, the fixed plate 31 can be attached at the local planar feature 2111 of the door frame sheet metal part 2, then the positioning plate 32 of the support 3 can be positioned with an external tooling clamp, and the fixed plate 31 of the support 3 is welded at the local planar feature 2111 of the door frame sheet metal part 2. For the door frame sheet metal parts 2 of different vehicle models, as long as they have the local planar feature 2111, the universality of the support 3 can be realized; or only the local planar feature 2111 needs to be designed on the door frame sheet metal parts 2 of different vehicle models, and the universality of the support 3 can also be realized, without affecting the overall shape and structure of the door frame sheet metal parts 2 of different vehicle models.
[0030] For the door frame sheet metal parts 2 of different vehicle models, as the size of the fixed plate 31 in at least one dimension direction is smaller than the size of the local planar feature 2111, when the fixed plate 31 is welded with the local planar feature 2111, the welding fixed position of the fixed plate 31 at the local planar feature 2111 in at least one dimension direction can be adjusted, thereby the universality of the support 3 to the door frame inner trim plates 1 of different vehicle models can also be improved. In addition, for different vehicle models, as the support 3 has high universality, when the vehicle model is changed, the welding tooling required for welding of the support 3 does not need to be changed. Ultimately, the production efficiency of the vehicle can be improved, and the cost can be reduced.
[0031] It should be noted that for the door frame sheet metal parts 2 of different vehicle models, when the support 3 is used, if the door frame sheet metal part 2 itself originally does not have the local planar feature 2111, the local planar feature 2111 can be formed by simply stamping at a local position of the door frame sheet metal part 2, thereby ensuring the universality of the support 3, and the overall shape and structure of the door frame sheet metal part 2 of different vehicle models can be maintained.
[0032] In summary, during the design phase, the universal bracket 3 reduces the workload of designing brackets 3 individually for different vehicle models, avoiding repetitive work and lowering design costs. In manufacturing, the universal bracket 3 reduces the frequency of tooling and fixture changes on the production line, improving production efficiency and further reducing costs. Regarding production cycle time, the universal bracket 3 simplifies the production process. During the welding and assembly of the bracket 3 with the door frame sheet metal part 2, workers do not need to frequently adjust different types of brackets 3, enabling faster welding operations. This helps improve production line cycle time and increase vehicle output. From a supply chain perspective, the universal bracket 3 facilitates centralized production and supply by suppliers. Suppliers can maintain a stockpile of universal bracket 3 in advance to meet factory needs promptly, reducing the risk of production interruptions and thus improving the efficiency of the entire vehicle manufacturing supply chain. Furthermore, because the universal bracket 3 is easier to manufacture, maintenance personnel do not need to search for special brackets 3 for specific vehicle models. The universal bracket 3 is applicable to multiple vehicle models, significantly shortening maintenance time and improving customer satisfaction.

Thus, when the fixing plate 31 is welded to the local planar feature 2111 of the door frame sheet metal part 2, the fixing plate 31 can be adjusted in both the first and second dimensions to improve the compatibility between them. Furthermore, by adjusting the welding position of the bracket 3 on the local planar feature 2111, the positioning plate 32 of the bracket 3 can be connected to the door frame interior panels 1 of different vehicle models, improving the versatility of the bracket 3 on the door frame interior panels 1 and door frame sheet metal parts 2 of different vehicle models.

[0050] It should be noted that the interior trim board horizontal bending part 111 of the A column lower interior trim board 11 is longitudinally butt jointed with the rocker interior trim board, and the interior trim board horizontal bending part 111 of the A column lower interior trim board 11 is also used to provide the decoration of the door frame bottom, and the interior trim board horizontal bending part 111 of the A column lower interior trim board 11 can also be called the rocker end interior trim board, and the rocker interior trim board butt jointed with the interior trim board horizontal bending part 111 can be called the rocker interior trim board body, and the rocker interior trim board body and the rocker end interior trim board jointly constitute the rocker interior trim board assembly of the door frame bottom.
