Description
Technical Field

Background
Compared with a traditional fuel vehicle, the electric vehicle has the following three problems that the local mode of the floor and the rigidity are insufficient more easily than the fuel vehicle.
Firstly, the electric vehicle is provided with an exhaust pipe, and a battery pack needs to be arranged below the front floor and the passage, so that the middle passage is generally designed to be close to a large-plane structure, and the battery pack is arranged below the floor, so that a beam frame structure cannot be arranged below the floor, the structure support is not arranged below the floor, and the electric vehicle can only rely on a seat beam above the floor to play a single-side support role.
Secondly, two seat crossbeams are generally arranged above the floor according to seats and are limited by factors such as seat installation, man-machine arrangement, column collision and the like, the seat crossbeams are generally designed to be closer to a front-row passenger area, so that the interval between the crossbeams in the two-row passenger area is larger, and the situation that the crossbeams have larger areas and are not supported by the seat crossbeams occurs.
Finally, aiming at the electric MPV (business vehicle) vehicle type, particularly paying attention to the requirement of large space and comfort of passengers, the pedal areas of the two rows of passengers are generally designed into a plane structure as much as possible, the influence on the pedal space due to the raised characteristics such as a beam frame structure and the like is avoided as much as possible, particularly, the high-end MPV vehicle type is provided with the two rows of passenger seats with slide rails and capable of being used for lying, the seats are required to slide to the last step extending space which still needs to be kept well, the plane areas of the pedal areas of the two rows of passengers are further enlarged, the local modes and insufficient rigidity of a floor are more likely to occur, and the problems of high-speed time plate shaking and pedal deformation are further caused.
The traditional solution is to spray damping fins or add beam frame structure to lift the front floor in the area with local mode and insufficient rigidity. The spraying damping fin can play a damping role, can reduce vibration, has certain improvement to floor shake, nevertheless improves the limit, only plays a role in certain scope, when the regional scope that rigidity is not enough is great, the effect of damping fin just receives the restriction, and the damping fin can't solve the problem of pedal deformation simultaneously.
