Abstract
A front-to-back through type floor longitudinal beam is characterized in that a front floor longitudinal beam, a middle passenger compartment lower longitudinal beam and a rear floor longitudinal beam are included; and the front floor longitudinal beam, the middle passenger compartment lower longitudinal beam and the rear floor longitudinal beam are welded and mounted together. The utility model has the advantages that force transmission can be guaranteed in head-on crash, a structure protruding outward is deformed to absorb energy during the side cash, so that the supporting force of a front seat cross beam and a back seat cross beam are shared, and the possibility of the middle passenger compartment deformation is reduced.
Description
Technical field
The utility model belongs to the technical field of auto body, particularly the through longitudinal floor beam in front and back.
Background technology
Longitudinal floor beam is not assembly members such as supported cart body, driving engine, actuating device and chassis suspension, is taking into account the transmission of power in the collision process and the effect of energy absorbing simultaneously.At present, in the car self-supporting body, the relative floor side member front end in front side member rear end is narrow on Width, and crew module's longeron is straight beam in the middle part of supporting, and longeron can not connect front and back before and after causing.When head-on crash took place, 70% of energy needed to be absorbed by chassis runner, and remaining energy and impact force will be transmitted backward by the longeron under the crew module of middle part.Usually longeron extends to front chair crossbeam or back seat crossbeam below under the crew module of design-calculated middle part, and like this, power can not be transmitted backward, can only crosswisely develop, though the collision result can satisfy crew module floor, rules middle part and seat crossbeam relative deformation is serious.
Summary of the invention
The utility model purpose provides the through longitudinal floor beam in a kind of front and back.
The technical solution of the utility model is achieved in that
The through longitudinal floor beam in front and back, it is characterized by: it is made up of longeron and floor floor side member under floor front side member, the middle part crew module, and longeron and floor floor side member welded and installed are together under floor front side member, the middle part crew module.
Can guarantee the transmission of power when the utility model benefit is head-on crash, in the side collision process, by the structural distortion absorption energy of outside protrusion, share the bearing force of front seats and back seats crossbeam, thereby reduced the possibility of middle part crew module's distortion.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The through longitudinal floor beam in front and back, it is characterized by: it is made up of longeron 2 and floor floor side member 3 under floor front side member 1, the middle part crew module, and longeron 2 and floor floor side member 3 welded and installed are together under floor front side member 1, the middle part crew module.
The through longitudinal floor beam in front and back is characterized by: the Eight characters structure of longeron 2 for outwards protruding under the described middle part crew module.
Embodiment:
Shown in Figure 1, the utility model has adopted through design concept, floor front side member 1, floor floor side member 3 is coupled together by longeron 2 under the crew module of middle part form the through structure in front and back; In the head-on crash process, energy remaining can be delivered to floor floor side member 3 by longeron 2 back kicks under the crew module of middle part, has expanded decomposition of force.
In configuration aspects, the utility model adopts the design concept that longeron 2 outwards protrudes under the crew module of middle part, and this structure can not only be carried load longitudinally, and it can also carry transverse load, has improved the horizontal load-carrying capacity in floor greatly.Can guarantee the transmission of power when this structural benefit is head-on crash, in the side collision process, by the structural distortion absorption energy of outside protrusion, share the bearing force of front seats and back seats crossbeam, thereby reduced the possibility of middle part crew module's distortion.
