Abstract

The utility model relates to the field of a car interior decoration, and aims at providing a front floor structure of a mini car. The front floor structure of the mini car is safe and not easy to curve or torsionally deflect when crashed. The front floor structure comprises a centre sill, a doorsill, a front cross beam, a front floor, a longitudinal beam, a back cross beam and an inclined bumping block. The longitudinal beam, the back cross beam and the inclined bumping block are integrated with the centre sill, the doorsill, the front cross beam and the front floor respectively. An included angle formed by the inclined bumping block and the longitudinal beam is in a range from 45 degrees to 55 degrees. The front floor structure of the mini car is more stable in connection, safe and not easy to curve or torsionally deflect when crashed, and improves overall intensity and stiffness. The included angle formed by the inclined bumping block and the longitudinal beam combines both the side collision resistant capability and the longitudinal collision resistant capability.

Description

Floor panel structure before the baby car
Technical field
The utility model relates to car interior trim field, not flexible or torsional deflection during especially a kind of collision, and safety is floor panel structure before the baby car preferably.
Background technology
Baby car has low, the light energy-conservation advantage of cost as walking-replacing tool; Along with baby car society recoverable amount increases day by day, people are to the safety growing interest of baby car; For when baby car crashes, reduce in-built distortion of baby car and damage as far as possible, protect the personal safety of driving person in the car to greatest extent, the anti-collision ability that strengthens the preceding floor panel structure of baby car is an important link; Floor panel structure before the baby car can obtain from the utility model of Chinese patent announcement CN200974562Y to understand; Floor crossmember welded assembly before this utility model disclosed a kind of baby car.Floor panel structure before the existing baby car, as shown in Figure 1: comprise central sill 1, threshold 2, front cross rail 3, preceding floor 4; One end of front cross rail is captiveed joint with central sill, and the other end of front cross rail is captiveed joint with threshold; The relative dual side-edge on preceding floor is captiveed joint with threshold is anterior with central sill is anterior respectively, and the back side edge on preceding floor is captiveed joint with the side of front cross rail; Floor panel structure before this kind baby car exists anti-collision ability relatively poor, easily bends or torsional deflection when crashing, thereby the crew module is deformed, even jeopardize occupant's deficiency; Therefore, not flexible or torsional deflection when designing a kind of collision, safety is floor panel structure before the baby car preferably, becomes problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is that the anti-collision ability of floor panel structure is relatively poor before overcoming present baby car, easily bends or torsional deflection when crashing, thereby the crew module is deformed, even jeopardize the deficiency of occupant safety; Not flexible or torsional deflection when a kind of collision is provided, safety be floor panel structure before the baby car preferably.
Concrete technical scheme of the present utility model is:
Floor panel structure before a kind of baby car comprises central sill, threshold, front cross rail, preceding floor; One end of front cross rail is captiveed joint with central sill, and the other end of front cross rail is captiveed joint with threshold; The relative dual side-edge on preceding floor is captiveed joint with threshold is anterior with central sill is anterior respectively, and the back side edge on preceding floor is captiveed joint with the side of crossbeam; Floor panel structure also comprises longeron, after cross member before the described baby car; One end of described after cross member is captiveed joint with central sill, and the other end of after cross member is captiveed joint with threshold; Described longeron one end is captiveed joint with front cross rail, and the other end of longeron is captiveed joint with after cross member.Floor panel structure is provided with longeron, after cross member and central sill, threshold, front cross rail before this baby car, preceding floor is integrally welded, makes the raising of bulk strength and rigidity, not flexible or torsional deflection during collision, and safety is better.
As preferably, also comprise diagonal cleat, described diagonal cleat one end is captiveed joint with threshold, and the other end is captiveed joint with longeron.Diagonal cleat is set, makes between threshold, front cross rail, longeron, after cross member to connect more firmly, bulk strength and rigidity further improve.
As preferably, the angle between described diagonal cleat and longeron is that 45 degree are to 55 degree.Take into account anti-broadside impact and resisting longitudinal collision requirement.
As preferably, described longeron is parallel with threshold; Described after cross member is parallel with front cross rail.Make easily.
The beneficial effects of the utility model are:
Floor panel structure is provided with longeron, after cross member, diagonal cleat and central sill, threshold, front cross rail before this baby car, preceding floor is integrally welded; Make connection more firm, bulk strength and rigidity improve, not flexible or torsional deflection during collision, and safety is better.Angle between diagonal cleat and longeron be 45 the degree to 55 the degree, take into account anti-broadside impact and resisting longitudinal the collision ability.Longeron is parallel with threshold, and after cross member is parallel with front cross rail, makes easily.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of floor panel structure before the existing baby car.
Among the figure: central sill-1, threshold-2, front cross rail-3, preceding floor-4, longeron-5, after cross member-6, diagonal cleat-7.
The specific embodiment
Below in conjunction with shown in the accompanying drawing the utility model is described further.
As shown in Figure 1: floor panel structure before a kind of baby car comprises central sill 1, threshold 2, front cross rail 3, preceding floor 4, longeron 5, after cross member 6, diagonal cleat 7; Threshold has two, is symmetrically distributed in central sill two sides; Front cross rail has two, is symmetrically distributed in central sill two sides; One end of front cross rail and central sill welding, the other end of front cross rail and threshold welding; Preceding floor has two, is symmetrically distributed in central sill two sides; Anterior and the anterior welding of threshold with central sill respectively of the relative dual side-edge on preceding floor, the back side edge on preceding floor and the welding of the side of crossbeam; After cross member has two, is symmetrically distributed in central sill two sides; After cross member is parallel with front cross rail; One end of after cross member and central sill welding, the other end of after cross member and threshold welding; Longeron has two, is symmetrically distributed in central sill two sides; Longeron is parallel with threshold; Diagonal cleat has two, is symmetrically distributed in central sill two sides; Diagonal cleat one end and threshold welding, the other end and longeron welding; Angle 50 degree between diagonal cleat and longeron;
Floor panel structure is provided with longeron, after cross member, diagonal cleat and central sill, threshold, front cross rail before this baby car, preceding floor is integrally welded; Make connection more firm, bulk strength and rigidity improve, not flexible or torsional deflection during collision, and safety is better.Angle between diagonal cleat and longeron is 50 degree, takes into account anti-broadside impact and resisting longitudinal collision ability.Longeron is parallel with threshold, and after cross member is parallel with front cross rail, makes easily.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.The conspicuous modification of the technical personnel to described field that all are such will be included within the scope of this claim.
