Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door protection, in particular to a vehicle door protection structure. Background Art

[0002] The car door provides a passage for the driver and passengers to enter and exit the vehicle, isolates them from interference outside the vehicle, reduces side impact to a certain extent, and protects the occupants. The side parts of the car door, such as the window frame, are mostly stamped or rolled with thin steel plates. During the assembly process of the car door, EPE foam plastic sheets are needed to protect the side of the car door.

[0003] The EPE foam plastic sheets used in existing car doors are basically made by cutting and processing foam plastic sheets. Thicker foam plastic sheets are used, and a T-slot structure is cut from the middle of the foam plastic sheet by a cutting knife so that the middle T-slot of the foam plastic sheet can be stuck in the side position of the car door that needs to be protected. However, cutting with thicker foam sheets will cause waste of the T-shaped component cut out in the middle, resulting in excess waste and unnecessary consumption during the cutting process of the EPE sheet. If multiple thin EPE sheets are used for bonding, instability will occur between the bonded EPE foam plastic sheets due to too little bonding surface. The bonded EPE foam plastic sheets are easy to separate, resulting in the car door protection structure composed of the EPE foam plastic sheets being unstable when used. Utility Model Content
