Abstract
It the utility model is related to a kind of beam joint structure, including crossbeam extension, the crossbeam extension is long slot structure, flange is provided with two sides of the crossbeam extension length direction, the flange is provided with Seat-fixed point, and the both ends of the crossbeam extension are connected with floor crossmember and longeron respectively.The beneficial effects of the utility model are：Solves the problems, such as the welding procedure of crossbeam and longeron overlap joint；Solves the problems, such as the durable road test part cracking TIR of vehicle；Solves general assembly seat assembly problem.
Description
Technical field
The utility model belongs to automobile manufacturing field, and in particular to a kind of beam joint structure.
Background technology
Current existing beam joint structure has following problem:
1st, welding procedure problem：The welding that seat reinforcing plate on crossbeam extension blocks crossbeam and longeron ovelapping spot weld is empty
Between, cause welding difficulty and quality of welding spot is difficult to ensure card；
2nd, durable road test problem：Crossbeam extension and big beam sides overlapping area are small, solder joint stress easily occur and concentrate cracking
TIR problems；
3rd, general assembly assembly problem：Diagram installation nut is seat installation group hole, is dispersed on 2 stamping parts, because welding misses
Difference influences, and pitch of holes is difficult to ensure card, general assembly assembling gear hole problem easily occurs.
Utility model content
The utility model proposes a kind of beam joint structure, solves the problems, such as the welding procedure of crossbeam and longeron overlap joint；Solve
The durable road test part cracking TIR problems of vehicle；Solves general assembly seat assembly problem.
What the technical solution of the utility model was realized in：
A kind of beam joint structure, including crossbeam extension, the crossbeam extension are long slot structure, are prolonged in the crossbeam
Two sides for stretching part length direction are provided with flange, and the flange is provided with Seat-fixed point, and the two of the crossbeam extension
End is connected with floor crossmember and longeron respectively.
Preferably, the bottom width of the crossbeam extension from one end that the floor crossmember is connected to the longeron
One end of connection is gradually widened.
Preferably, the bottom of the crossbeam extension is in bell mouth shape.
Preferably, the flange of the crossbeam extension is provided with strengthening rib strip.
The beneficial effects of the utility model are：
(1) crossbeam extension and seat reinforcing plate are merged into single stamping parts, one set of die and welding tooling can be reduced
Exploitation, when saving the Welder of seat reinforcing plate and crossbeam extension；
(2) crossbeam extension and seat reinforcing plate are merged into single stamping parts, avoided because seat reinforcing plate blocks crossbeam
With the welding space of longeron ovelapping spot weld, solve the problems, such as crossbeam extension and big beam sides solder joint difficulty welding procedure；
(3) crossbeam extension is designed as " horn mouth " formula structure, the overlap joint of crossbeam extension and big beam sides can be increased
Area, crossbeam extension is formed " triangle " closing chamber just with longeron, improve structure bonding strength, solve solder joint cracking
TIR problems；
(4) Seat-fixed point is arranged on single stamping parts crossbeam extension, easily controllable one-piece part size, can be with
Avoid the seat installation pitch of holes caused by welding error from not conforming to, improve Seat-fixed point installation accuracy, it is total to solve seat installation
Dress gear hole problem.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the beam joint structure described in the utility model embodiment；
Fig. 2 is the beam joint structure and floor crossmember and the scheme of installation of longeron described in the utility model embodiment.
In figure：
1st, crossbeam extension；2nd, flange；3rd, Seat-fixed point；4th, floor crossmember；5th, longeron；6th, strengthening rib strip.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1-2, the beam joint structure described in the utility model embodiment, including crossbeam extension 1, the horizontal stroke
Beam extension 1 is long slot structure, and flange 2, the flange 2 are provided with two sides of the length direction of crossbeam extension 1
Seat-fixed point 3 is provided with, the both ends of the crossbeam extension 1 are connected with floor crossmember 4 and longeron 5 respectively.
In this example, the bottom of the crossbeam extension 1 is in bell mouth shape.
In this example, the flange 2 of the crossbeam extension 1 is provided with strengthening rib strip 6.
The flange of crossbeam extension and floor crossmember welding edge lap is done to the welding for greatly, setting seat to install nut (will
Seat reinforcing plate and crossbeam extension are designed to a part, can reduce exploitation and the welding tooling of a set of diel), and increase
Sinew adding strip improves the intensity of mounting surface.
By the upper increasing in X direction of the cavity (vallecular cavity) of crossbeam extension and longeron overlap joint, the overlap joint of increase cavity and longeron
Area, keep constant with floor crossmember lap cavity bulk area, form " horn mouth " formula structure, forming " triangle " cavity with longeron takes
Binding structure.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
