Technical Field
The utility model relates to an automobile body structure especially relates to a can provide preceding floor crossbeam structure that side post bumps support.
Background
The New energy automobile industry develops rapidly, the collision safety of the New energy automobile battery system is more and more emphasized, and the C-NCAP (China-New Car Association Program) also brings the side column collision into the Assessment range.
The front floor beam structure for the collision of the side pillars in the market at present is generally an integral beam structure, as shown in fig. 1, and comprises a whole beam 1, two sides of the whole beam 1 are respectively provided with a connector 10, and the connectors 10 are respectively connected with doorsills on two sides of a vehicle body. Because the front floor beam structure provides support for the side column collision, the beam structure is made of high-strength steel materials. However, the existing integrated beam structure has the following defects:
the Y-direction size of the integral beam structure is wide, so that a mold for manufacturing the beam is large, and the development cost is greatly increased; on the other hand, because of the middle channel, the cross beam structure has abrupt height change at the middle channel position, so that the cross section of the cross beam at the middle channel position forms abrupt height change, and the abrupt height change can increase the forming difficulty of high-strength steel in production and manufacturing.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a can provide the front floor beam structure that the side post bumps the support, it can satisfy the side post and bump the support, can reduce development cost and reduce the formability degree of difficulty simultaneously by a wide margin.
The purpose of the utility model is realized by adopting the following technical scheme:
a front floor beam structure providing side impact support, comprising:
an intermediate connecting member;
one end of each beam body is connected with the middle connecting piece;
and the two threshold joint pieces correspond to the cross beam body one to one, and one end of each threshold joint piece is connected with the other end of the corresponding cross beam body.
Preferably, the beam body and the middle connecting piece are fixed through welding.
Preferably, the threshold joint piece and the beam body are fixed by welding.
Preferably, the middle connecting piece is a bent structure which extends upwards from two ends to form a protrusion.
Preferably, the intermediate connecting member includes an intermediate portion, two horizontal portions and two inclined portions, the horizontal portions correspond to the inclined portions one to one, one end of each horizontal portion is connected to one end of the corresponding inclined portion, the inclined portion is inclined upward from one end connected to the horizontal portion toward a direction away from the horizontal portion, and the intermediate portion is connected between the other ends of the two inclined portions.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses fall into front floor crossbeam structure and form by the equipment of three kinds of subassemblies of intermediate junction spare, crossbeam body, threshold connector spare, avoided the integral crossbeam structure of prior art to need the problem that the mould is big, development cost is big, and the utility model provides a front floor crossbeam structure can provide the side post and bump the performance requirement of support.
