Abstract
The utility model provides a floor for electric vehicles. In order to ensure strength and rigidity and allow the floor structure to resist external force causing lateral collision to a vehicle, lower longitudinal beams and reinforcing beams perpendicularly crossing with transverse beams are disposed on the surface of the floor structure. The floor has sufficient strength originally and is safe and reliable, so that vehicle rigidity and tightness are improved, vehicle weight is decreased, vehicle cost is lowered and economy of the vehicle is improved. A frame structure is reasonably configured, floor strength and space are sufficient, and the requirements of electric chassis systems of electric vehicles are met. The floor is formed by stamping flat and smooth sheet metal, the periphery of the floor is provided with an upward flange and punched holes, and the transverse beams and the longitudinal beams are symmetrical. The transverse beams and the longitudinal beams are welded on the floor by spot welding and form an inverted 'T' shape. In addition, the reinforcing beams transversely penetrate the whole floor, and the strength of the floor is further enhanced. The floor system is structurally stable, so that vehicle safety is improved and safety of the electric vehicle and drivers and passengers is protected effectively.
Description
Technical field
The utility model relates to the electric vehicle engineering field, relates in particular to the structure on a kind of electronlmobil floor.
Background technology
Electronlmobil is more and more general in actual life, and the electronlmobil of low-carbon (LC), joint source property, safety is more and more approved by users.In the safety and layout performance that guarantee electronic automobile, the floor plays an important role simultaneously.Electronlmobil is in Fast Urbanization, industrialization, and electronlmobil has environmental protection, the advantage such as energy-conservation, light, safe.Electronlmobil has solved the crisis of the energy and the pollution of environment, in the process of technology innovation, adheres to the support of government, the principle of attaching most importance to core technology, critical component and the system integration.
In the floor panel structure, the strength beam of following longitudinal and cross beam square crossing is set in floor in order to can keep out the external force in vehicular sideview when collision in order to ensure strength rigid.Can when suppressing tare, improve significantly the rigidity on floor by this reinforced rib.Floor itself should have enough intensity, makes the seat multi pack convenient, safe and reliable, improves rigidity and the leak tightness of car load, and complete vehicle quality reduces, and reduces integral vehicle cost, improves economy.The skeleton structure connection and reasonable arrangement, floor intensity and space are sufficient, satisfy the demand of electronlmobil electric power chassis system.Stablizing of floor system structure increased the safety performance of car load.
The utility model content
Electronlmobil and driver and crew's safety for it can fully absorb automobile at the energy that occurs to produce when initiatively colliding, has been protected effectively in a kind of electronlmobil floor that the utility model provides.Also can easily load on-vehicle parts on the panel on strength beam floor, but also the rigidity can guarantee to improve the rigidity on floor and improve side collision by strength beam the time.
The technical solution of the utility model: the length on described floor is that 1387mm, width are that the panel beating thickness on 1135mm, floor is 1mm; The floor is stamped to form by sheet metal component, arranges all around to the upper overturning punching, and the crossbeam longeron is symmetrical.Crossbeam and longeron point are welded on the floor, and crossbeam becomes " protruding " type structure with the longeron section; Strengthen simultaneously longeron and laterally run through whole floor, further strengthened the intensity on floor.Comprise longeron assembly under smooth-going floor, the floor, floor crossmember assembly.Longeron assembly, the spot welding of floor crossmember assembly connect into a unitary construction under described floor, the floor, and structure is strengthened in the reinforcement square crossing under longeron assembly and the floor, is parallel to each other between longeron assembly or the floor cross sill assembly.Intensity strengthens greatly, can satisfy the installation of car inner component, promoted to a certain extent the spacial ability of electronlmobil, promoted the stability of electronlmobil under body in motion, reduced because impacting the excessive a series of faults such as sheet metal component fracture by fatigue that produce.And all be " protruding " type structure along the symmetrically arranged longitudinal and cross beam section of front floor main center's line, by such structure, act on the strength beam of floor panel, joist support is subjected to certain load, the load of directly transmitting on the strength beam, strength beam links together and carries the summation of transmitted load, thereby this load is disperseed transmission by strength beam, has the advantages such as Joint strenght is good, load-carrying capacity is good.
Described floor is that smooth-going smooth sheet metal component is stamped to form, and arranges all around to the upper overturning punching, and the crossbeam longeron is symmetrical.Crossbeam and longeron point are welded on the floor, and crossbeam becomes " protruding " type structure with the longeron section; Longeron runs through whole floor simultaneously, has further strengthened the intensity on floor.
On the floor, between the longeron or parallel between the crossbeam, longitudinal and cross beam square crossing point is welded on the floor described longitudinal and cross beam by multi-point welding.
It is that 1135mm, width are the crossbeam of 66mm that described longeron has a length, and point is welded in the middle side on floor; Two length of the both sides spot welding on floor are that 1436mm, width are that the girder of 48mm vertically is applied in whole floor, and at the head of girder support are set, and are fixed on car load front-axle beam place.
Described crossbeam is that section becomes " protruding " type structure, and the crossbeam width is 48mm, traverses the bottom on the floor, strengthens the intensity on whole floor.

The specific embodiment
Arrange to the upper overturning punching around being provided with around the floor panel, floor cross sill beam and longeron point are welded on the floor, and three crossbeams become " protruding " to play shape with three longerons.Strength beam traverses on whole floor simultaneously, has further strengthened the intensity on floor.Longeron be installed in respectively on the floor and extend to panel the outside as body framwork, left-right longeron is symmetrical arranged along front floor main center line, and at the head of girder support is set, and is fixed on car load front-axle beam place, afterbody and trunk are closely fixing, guarantee that the floor is firmly stable.Middle crossbeam is implemented 2/3rds of floor, fixedly the parts in vehicle body space.Crossbeam is evenly distributed in the lower end on floor, extends to the both sides on floor, and both sides arrange fixed support and closely connect in vehicle body.Square crossing spot welding by longeron and crossbeam is parallel to each other between longeron or the crossbeam, guarantees that intensity, the load on floor has good performance.
