The beam body 110 is provided with a mounting cavity 111 and a first mounting channel 112 which is communicated with the mounting cavity 111 and penetrates through the beam body 110; the bushing body 120 is provided with a second mounting channel 121, the bushing body 120 is disposed in the mounting cavity 111, an end of the bushing body 120 abuts against an inner wall of the mounting cavity 111, and the second mounting channel 121 is communicated with the first mounting channel 112.
In the side sill 100 of the above embodiment, the bushing body 120 is disposed in the mounting cavity 111 of the sill body 110, so that both ends of the bushing body 120 abut against the inner wall of the mounting cavity 111. When the side sill 100 needs to be connected with the vehicle body, the side sill 100 can be fixed on the vehicle body by using connecting pieces such as bolts only through the first mounting channel 112 and the second mounting channel 121. Meanwhile, the bushing body 120 can prevent the connecting member from wearing or extruding the inner wall of the mounting cavity 111, so that the side sill 100 can be stably and reliably connected with the vehicle body.
In a conventional method, the bushing includes a bushing body 120 and a flange disposed at an upper end of the bushing body 120, and the bushing body 120 is inserted into the mounting cavity 111, so that the bushingThe lower end of the sleeve body 120 is attached to the inner wall of the mounting cavity 111, so that the side wall of the flange is attached to the upper side wall of the beam body 110; when the bush receives the exogenic action, the lower extreme of bush body 120 applys decurrent effort to the downside of roof beam body 110, and the flange also applys decurrent effort to roof beam body 110 upside to make roof beam body 110 have the trend of contracting to installation cavity 111, easily take place to contract and warp, influence the structural feature of boundary beam 100, thereby make boundary beam 100 unable and automobile body realize stable, reliable being connected. In the edge beam 100 of the above embodiment, when the bushing body 120 is acted by an external force, the lower end of the bushing body 120 exerts a downward acting force (see F in fig. 3)2Shown) to the underside of the beam body 110, the upper end of the bushing body 120 applies an upward force (see F in fig. 3)1Shown) to the upper side of the girder body 110, thereby preventing the girder body 110 from being shrunk and deformed, and securing the structural characteristics of the side girder 100, so that the side girder 100 can be stably and reliably connected with the vehicle body.
Meanwhile, in the conventional method, in order to avoid the sliding of the bushing, the lower side wall of the flange and the upper side wall of the beam body 110 need to be welded for fixing, in the welding process, welding slag easily enters between the lower side wall of the flange and the upper side wall of the beam body 110, so that the flatness of the bearing surface of the upper end of the bushing body 120 cannot meet the requirement, the bearing surface of the upper end of the bushing body 120 cannot be matched with a finished automobile closing hole, the bearing surface of the upper end of the bushing body 120 generally needs to be polished, the working hours are consumed, the operation is troublesome, and the cost is increased.
