Specific embodiment
Fig. 1 to Fig. 6 below in conjunction with the accompanying drawings is described in further detail to a kind of beam and longitudinal beam connecting assembly of the present invention.
A kind of beam and longitudinal beam connecting assembly of the present invention, refer to Fig. 1 to Fig. 6, including crossbeam 1 and longeron 2 and for even Connect the connector 3 of described crossbeam 1 and longeron 2, described connector 3 crossbeam 1 two lateral walls corresponding position is provided with docking Opening 4, described connector 3 is the blocks of hollow, and the middle part of described connector 3 two side is respectively provided with connection opening 5, described horizontal stroke Docking opening 4 on beam 1 is corresponding with connection opening 5 position of described connector 3, shape and size, and described connector 3 side wall exists Described connection opening 5 at be provided with the outside wall 6 that turns up, described crossbeam 1 is connected with described connector 3, described longeron 2 with described Connector 3 connects, and described connector 3 embeds at the described docking opening 4 of described crossbeam 1, and described longeron 2 embeds described connector At 3 connection opening 5.So, first connector 3 and crossbeam 1 are connected, then again longeron 2 are connected with connector 3 solid Fixed, such crossbeam 1 is more firm with being connected of longeron 2, and crossbeam 1 and longeron 2 all do not have U-shaped turnup structure, shape Easily, simplify mould development work, and the quality of crossbeam 1 and longeron 2 controlled, eliminate that part panel beating is wrinkling, hidden split Phenomenon.And the connection of crossbeam 1 and longeron 2 is more firm, improve vehicle body partial structurtes intensity and safety concerns.And connect Part 3 is independent component, shapes the wall that turns up thereon and is easier, i.e. shaping is compared formation U-shaped flange on crossbeam 1 and is more prone to, And it is more firm with the connection of crossbeam 1 and longeron 2.Do not interfere with crossbeam 1 and the quality of longeron 2.Dock opening 4 and be connected Opening 5 position.The corresponding effect of shape and size is to facilitate crossbeam 1 and longeron 2 to be connected and fixed by connector 3.
A kind of beam and longitudinal beam connecting assembly of the present invention, refer to Fig. 1 to Fig. 6, concrete on the basis of previous technique scheme Can be that described crossbeam 1 is connected with the outer surface of the side wall of described connector 3, the wall that turns up of described longeron 2 and described connector 3 6 inner surface connects.Certainly can also be that others are connected mode, as long as crossbeam 1 can be connected with connector 3, And longeron 2 is connected with connector 3, and because wall 6 Area comparison that turns up is big, therefore longeron 2 is solid with the connection of connector 3 Fixed more firm.Further preferred technical scheme is that the inner surface of described crossbeam 1 two side is located at described docking opening 4 both sides Position at connect positioned at the described outer surface connecting opening 5 both sides with described connector 3.So, crossbeam 1 and connector 3 Junction be four joint faces be fixedly connected mode, be fixedly connected area big, it is to avoid stress concentration, and be fixedly connected more Firmly.It is further ensured that the quality of car load vehicle body.Further preferred technical scheme is that described crossbeam 1 is located at described docking opening Basal surface at 4 is connected with described connector 3 basal surface.So, because connector 3 bottom area ratio is larger, therefore further Increased a joint face, increase connection area, improve the firmness being fixedly connected.Can also be the two side of described longeron 2 Outer surface contact with the inner surface of the wall 6 that turns up of described connector 3.So, due to difference in the middle part of two side walls of connector 3 One connection opening 5 of setting, and connector 3 has, at connection opening 5, the wall 6 that turns up turning up, therefore, connector 3 has two companies Connect opening 5 and four walls 6 that turn up, the wall outer surface of longeron 2 is connected with corresponding this four walls 6 that turn up, and joint face is equal For plane, junction area is big, it is to avoid stress concentration, and is fixedly connected more firm.
A kind of beam and longitudinal beam connecting assembly of the present invention, refer to Fig. 1 to Fig. 6, on the basis of foregoing technical scheme On, can also be that described crossbeam 1 is welding with the connection of described connector 3, described longeron 2 with the connection of described connector 3 is Welding.The fixed form of welding more firmly and also low cost.Can also be that described connector 3 connects the outside water in opening 5 bottom Square to be extended have gripper shoe 7 of turning up, described longeron 2 bottom is contacted with described gripper shoe 7 of turning up.Turn up the work of bracing frame With being the active force between longeron 2 and connector 3 can be mitigated, it is to avoid between longeron 2 and connector 3 with the weight of support stringer 2 The disengaging that misplaces because of interaction force is fixedly connected.Technical scheme still more preferably is described gripper shoe 7 and the longeron 2 of turning up Bottom welding.The face that is fixedly connected so between connector 3 and longeron 2 increased two again, is fixedly connected more firm.Separately Outward, the stain in all accompanying drawings is pad 8.Can also be described longeron 2 and described crossbeam 1 top side wall be provided with to The flanging 9 of outer upset, the flanging 9 that the flanging 9 of described longeron 2 docks opening both sides with described crossbeam 1 offsets.
Above-mentioned only several specific embodiments in the present invention are illustrated, but can not be used as the protection model of the present invention Enclose, the equivalence changes done by design spirit in every foundation present invention or modification or equal proportion zoom in or out, all should Think and fall into protection scope of the present invention.
