This invention provides a door assembly structure and vehicle, belonging to the field of automotive door technology. It includes an inner door panel and an outer door panel, with an outer panel reinforcing plate, an outer panel support plate, a door anti-collision beam, and a door lock reinforcing plate disposed between the inner and outer door panels. The outer panel reinforcing plate, outer panel support plate, and door anti-collision beam are arranged sequentially from top to bottom. The door assembly structure provided by this invention utilizes a first force transmission channel and a second force transmission channel to transmit the impact force of a side impact on the door assembly to the vehicle body, reducing the degree of inward indentation of the door, ensuring door strength, improving its rigidity, and achieving improved NVH performance. The structure is arranged in three directions (X, Y, and Z) to ensure that the structure can transmit force in each direction. The triangular adhesive area forms an adhesive fixation for the outer door panel, significantly improving the stability of the outer door panel installation.

The application discloses a PCB conveying system and a PCB conveying method. The PCB conveying system comprises a conveying module and a supporting plate module. The conveying module is arranged along a preset conveying path and is used for conveying a PCB. Two groups of inclined conveying surfaces are formed on the conveying module. The two groups of conveying surfaces are arranged on two sides in the width direction of the conveying path, and the lower sides of the two groups of conveying surfaces are close to each other. The supporting plate module is arranged along the conveying path. The two groups of conveying surfaces can support the PCB at two edges in the width direction of the conveying path, thereby reducing the contact area between the conveying surface and the PCB, and reducing the damage of the board surface of the PCB in the conveying process. The supporting plate module can support the middle part of the PCB without friction with the board surface of the PCB, so that the PCB conveying system can convey the PCB with a relatively small thickness.
