Larger and wider entrance doors can give the house a more majestic appearance and visual experience, and the quality requirements for products are gradually increasing. However, as the size of the entrance door increases, the structural strength of the middle part of the entrance door leaf will be weakened, resulting in an increased probability of deformation of the entrance door leaf under external force. Utility Model Content
[0003] The purpose of the utility model is to provide an entrance door leaf and an entrance door assembly with an anti-deformation structure, by structurally reinforcing the middle part of the entrance door leaf, thereby improving the structural strength of the entrance door leaf so that the entrance door leaf can adapt to requirements of larger sizes.
[0004] In a first aspect, the utility model provides an entrance door leaf with an anti-deformation structure, comprising:
[0005] Door frame;
[0006] A first decorative panel is arranged on a side of the door leaf frame close to the outside of the room;
