[0002] The automobile floor structure is an important part of the automobile body. It not only bears the weight of passengers and cargo, but also bears the load, vibration, impact and torque generated during the movement of the car. The front floor assembly in the automobile floor structure mainly bears the front seats and has a load-bearing task. The rear floor assembly mainly bears the rear seats, spare tires, fuel tanks, etc. The middle floor structure connects the front floor structure and the rear floor structure to form a continuous body bottom structure.

[0003] During the design process, it is necessary to consider the structural form of the vehicle body, the requirements for the interior layout, load distribution, vibration and shock absorption, etc. The floor structure must not only withstand static loads, but also dynamic loads such as the forces generated during acceleration, braking and cornering.

[0004] In current automobile design, the center floor structure is flat as a whole. In order to increase the structural strength, the center floor structure is arranged with different degrees of concave and convex areas, which provide poor support for the seat cushions, causing a more obvious foreign body sensation and a poor driving experience. In addition, there is a risk of seat diving at the center floor structure, which will increase the damage to the abdomen of the occupants in a vehicle collision accident. During the deceleration stage of a vehicle collision, due to the imbalance of the combined force acting on the pelvis (including the effects of the seat, seat belt, etc.), the seat belt will slip, deviate from the normal use position, slide from the pelvis to the abdomen, and directly apply the corresponding load force to the abdomen, causing injuries to the passenger's abdominal soft tissue and unreasonable space layout. Summary of the invention

[0005] In view of the defects existing in the prior art, the present application provides a middle floor structure, a body floor assembly and a vehicle to solve the problems of poor driving experience and poor overall stability caused by the middle floor structure in the prior art.
