Description

A kind of lightweight new-energy automobile subframe floor side member
Technical field
Electric car body technical field is the utility model is related to, more particularly to a kind of new source automobile accessory frame of lightweight Floor side member.
Background technology
Main force of the electric automobile as Future New Energy Source automobile, has the huge market space, electric automobile is due to it Structure is simple relative to traditional fossil energy vehicle structure, easily manufactured, is much less manufacturing link, therefore relative cost Relatively low, Just because of this, many electric automobile manufacturers use inferior materials and turn out substandard goods, and workmanship is unqualified, cause many accidents to be sent out It is raw.Automobile chassis vehicle frame is one of critical piece of automobile, and the left and right floor side member of automobile accessory frame is to install engine in car Mount point after two on frame, most of automobile rear longitudinal girder are carrying out reinforcing rib welding after using punch forming to inner wall, so that Reach the requirement of integral strength.The floor side member quality of punch and weld is all heavier, and welding deformation be it is inevitable, Engine is higher to the position accuracy demand of vehicle frame mount point, so the processing technology requirement of floor side member is at a relatively high.In order to drop Low vehicle frame weight, improves engine installation accuracy, reduces driving vibrations, it is necessary to carry out shape and structural adjustment to floor side member with full Sufficient lightweight demand.
The content of the invention
According to the above problem, the purpose of this utility model is to provide indulged after a kind of lightweight new-energy automobile subframe Beam, expansion disposal molding is carried out by way of being heated to section bar to floor side member, achievees the purpose that lightweight floor side member.
The technical solution of the utility model is achieved in the following ways:After a kind of lightweight new-energy automobile subframe Longeron, is made of floor side member left part, floor side member middle part, floor side member right part, and floor side member is integrally heated using overall pipe, overall round Pipe one end blocks, and other end expands pipe using high pressure oil pressure pipe by pushing hydraulic oil, is finally reached disposal molding Purpose, it be one end rectangular configuration that the floor side member left part, which is overlooked, and one end is trapezium structure, and section is the concordant ellipse in both sides Shape structure, side view are that lower section is plane and with the horizontal certain acute angle, and upper surface is left end plane, right end arc-shaped transitional surface knot Structure, it is rectangular configuration that floor side member middle part, which is overlooked, and section is the concordant ellipsoidal structure in top and bottom, lower surface and floor side member Left part lower surface is in alignment, it is characterised in that:The floor side member right part connects into S type structures with floor side member middle part, after Longeron right part upper surface is higher than upper surface in the middle part of floor side member.
The left connecting hole fixed with vehicle frame and right connection are respectively arranged with the floor side member left part and floor side member right part Hole, floor side member middle part set four engine mounting holes, facilitate engine integrally to be dismounted from vehicle frame.
The utility model, by floor side member one-pass molding, vehicle frame integral strength is also ensure that while lightweight vehicle frame And rigidity, while the process for decreasing processing floor side member, saving of work and time.
Brief description of the drawings
Fig. 1 is a kind of lightweight new-energy automobile subframe floor side member front view of the utility model.
Fig. 2 is a kind of lightweight new-energy automobile subframe floor side member top view of the utility model.
Figure is the utility model structural reinforcement member schematic diagram.
In figure:1 floor side member left part, 2 floor side members middle part, 3 floor side member right parts.
Embodiment
Known by Fig. 1, Fig. 2, a kind of lightweight new-energy automobile subframe floor side member schematic diagram of the utility model, by floor side member 2, floor side member right part 3 forms in the middle part of left part 1, floor side member, and floor side member is integrally heated using overall pipe, overall one end seal of pipe Stifled, other end expands pipe using high pressure oil pressure pipe by pushing hydraulic oil, disposal molding is finally reached, after described It is one end rectangular configuration that longeron left part 1, which is overlooked, and one end is trapezium structure, and section is the concordant ellipsoidal structure in both sides, and side view is Lower section is for plane and with the horizontal certain acute angle, and upper surface is left end plane, and right end arc-shaped transitional surface structure, described is rear vertical 2 vertical views are rectangular configuration in the middle part of beam, and section is the concordant ellipsoidal structure in top and bottom, lower surface and 1 lower surface of floor side member left part In alignment, the floor side member right part 3 connects into S type structures with the middle part of floor side member 2, and 3 upper surface of floor side member right part is higher than 2 upper surfaces in the middle part of floor side member, are respectively arranged with the left company fixed with vehicle frame on the floor side member left part 1 and floor side member right part 3 Hole 1-1 and right connecting hole 3-1 are met, 2 set four engine mounting holes 2-1 in the middle part of floor side member.
Beneficial effects of the present invention:1st, by floor side member one-pass molding, vehicle frame is also ensure that while lightweight vehicle frame Integral strength and rigidity, while the process for decreasing processing floor side member, saving of work and time;2nd, by sinking in the middle part of the floor side member of formula Design, engine mounting positions are more compact and floor side member is integrally more difficult deforms upon;3rd, the rear vertical of design for disassembly is passed through Beam, can facilitate engine integrally to be dismounted from vehicle frame.
