Abstract
The invention provides a front floor central tunnel assembly for a car body, which has leak tightness and high direct impact performance. The front floor central tunnel assembly for the car body comprises a central channel body and a central channel bracket body, wherein the central tunnel bracket body is hermitically fixed on the central tunnel body through flanges at the periphery, and technological holes of the central tunnel assembly are arranged on the central channel bracket body. As the central tunnel bracket body separated from the central tunnel body is arranged and the technological holes are arranged on the central tunnel bracket body, holes on the central tunnel body are avoided; moreover, as the central tunnel bracket body is hermetically fixed on the central tunnel body, no communication between the technological holes on the central tunnel bracket body and the outside to the car body is guaranteed, and the problem of leakage noise of the technological holes is solved; and meanwhile, the cross section of the front floor central tunnel assembly is increased due to the additional arrangement of the central tunnel bracket body, the number of closed sections is increased, and the direct impact performance is improved.
Description
Technical field
The present invention relates to auto body manufacturing technology field, be specifically related to passage assembly in a kind of front floor of automobile body.
Background technology
Passage assembly in the front floor of existing auto body is because part car auxiliary hole is too much, can cause in the car wind excessive problem of making an uproar in wind make an uproar when experiment, and the passage assembly is that the monolithic steel are one-body molded in the majority, its cross section is sealed close the cross section number less, and the central collision performance is not high.
Summary of the invention
The objective of the invention is to propose a kind of passage assembly in the high front floor of automobile body of leak tightness and central collision performance that has.
According to passage assembly in the front floor of automobile body provided by the invention, key is to comprise middle channel body and middle channel bracket body, described middle channel bracket body is fixed on the described middle channel body by flange sealing all around, and the auxiliary hole of described middle passage assembly is arranged on the described middle channel bracket body.
The passage assembly is by arranging a middle channel bracket body that separates with middle channel body in the front floor of automobile body of the present invention, auxiliary hole is arranged on the middle channel bracket body, thereby avoid perforate on middle channel body, and middle channel bracket body sealing is fixed on the middle channel body, guaranteed that the auxiliary hole on the middle channel bracket body does not communicate with the vehicle body external world, has solved the leakage sound problem of auxiliary hole; Simultaneously, owing to having increased middle channel bracket body, so that the sectional area of passage assembly increases in the front floor, and has increased the closed cross-section number, promoted the central collision performance.
Further, described middle channel bracket body around vertically be furnished with some to reinforced rib.By reinforced rib being set, the central collision performance of channel bracket body in the increase.
Further, better embodiment be middle channel bracket body vertically before, during and after end arrange three pairs of reinforced ribs.
Further, the both sides of the front end of described middle channel bracket body are fixed by clamp and middle channel body, to prevent the up perk when collision is stressed of middle channel bracket body front end, cause danger.
Further, the passage assembly also comprises the middle passage extension plate that is connected with middle channel body in the described front floor of automobile body, and middle passage better is connected with the body structure part.
Further, the rear portion of described middle channel bracket body is the inclined-plane, makes middle channel bracket rear body have the crumple space, increases safety.
Further, described middle channel bracket body is fixed on the described middle channel body by welding manner.Leak tightness during welding technique by good seal performance such as wind welderings just can guarantee between channel bracket body and the middle channel body.
Description of drawings
Fig. 1 is the structural representation of passage assembly in the front floor of automobile body of the present invention.
Fig. 2 is the exploded view of passage assembly in the front floor of automobile body of the present invention.
Fig. 3 is the section drawing of passage assembly in the front floor of automobile body of the present invention.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Such as Fig. 1, the passage assembly comprises middle channel body 1 and middle channel bracket body 2 in the front floor of automobile body of the present invention, middle channel bracket body 2 is fixed on the middle channel body 1 by flange sealing all around, and the auxiliary hole of middle passage assembly (comprising parking brake mounting hole, gearshift mounting hole, ECU module and wire harness hole etc.) is arranged on the middle channel bracket body 2.The three pairs of reinforced ribs 11,12 and 13 before, during and after vertically being furnished with around the middle channel bracket body 2.The both sides of the front end of middle channel bracket body 2 are fixed by clamp 3 and middle channel body 1.The passage assembly also comprises the middle passage extension plate 4 that is connected with middle channel body 1 in the front floor of automobile body.The rear portion of middle channel bracket body 2 is the inclined-plane.Middle channel bracket body 2 is fixed on the middle channel body 1 by welding manner.
The passage assembly is by arranging a middle channel bracket body 2 that separates with middle channel body 1 in the front floor of automobile body of the present invention, auxiliary hole (comprising parking brake mounting hole, gearshift mounting hole, ECU module and wire harness hole etc.) is arranged on the middle channel bracket body 2, thereby avoid perforate on middle channel body 1, and middle channel bracket body 2 sealings are fixed on the middle channel body 1, guaranteed that the auxiliary hole on the middle channel bracket body 2 does not communicate with the vehicle body external world, has solved the leakage sound problem of auxiliary hole; Simultaneously, owing to having increased middle channel bracket body 2, so that the sectional area of passage assembly increases in the front floor, and has increased the closed cross-section number, promoted the central collision performance, as shown in Figure 3, wherein, M is car room, and N is outdoor automobile.
