As shown in Figures 2 and 4, which includes the first connector 201 and the second connector 202, first connection
Part 201 is equipped with an articulated section 25, is additionally provided with an arc groove 26 inside the articulated section 25, which sets
There is convex block 27 compatible with 26 shape of the arc groove, which can be embedded in the arc groove 26, second connection
Part 202 can be rotated with the convex block 27 for rotation center.
Specifically, 20 front end of the connector is equipped with the first splicing face 21 and second splicing face 22, wherein first splicing
Face 21 is located on first connector 201, which is located on second connector 202, the first splicing face 21
It is opposite with the second splicing face 22 and be arranged in parallel in 10 left and right sides of cabin longeron assembly.The first splicing face 21 and the second glue
Junction 22 passes through structure glue connection with 10 left and right sides of cabin longeron assembly.
20 rear end of connector is additionally provided with the third being connect with the front wall crossbeam 30 and is glued face 23 and the 4th splicing face 24,
The third is glued face 23 and the 4th splicing face 24 is arranged in parallel.It is in ladder that the third, which is glued face 23 and the 4th and is glued face 24,
Shape, it is in convex shape structure that the third, which is glued face 23 to be located at about 24 both sides of the 4th splicing face, and the described 4th is glued face 24
Far from the cabin longeron assembly 10.
It should be understood that the first splicing face 21, the second splicing face 22 are glued face 23 with the third and are mutually perpendicular to, institute
The first splicing face 21, the second splicing face 22 and the 4th splicing face 24 is stated to be mutually perpendicular to.
Wherein, it is equipped with a bonding plane (the non-label of figure) on first connector 201 and the second connector 202, described the
Two connectors 202 are embedded in by the convex block 27 in the articulated section 25, and direction shown in arrow rotates along Fig. 4, makes two bonding planes
Be bonded to each other, this first be glued face 21 with second splicing face 22 it is parallel and with 10 left and right sides face paste of cabin longeron assembly
It closes (as shown in Figure 5).
To ensure to be glued the bonding strength in region, it is glued face 21, second described first and is glued the splicing face of face the 22, the 4th
24 and first connector 201 and the second connector 202 bonding plane on be equipped with coating groove (the non-label of figure), in this implementation
In example, the depth of the coating groove is 0.2mm, and splicing region is made to possess enough structure glues, and the clear zone of action.
As shown in Figure 2, Figure 6 and Figure 7, the front wall crossbeam 30 includes front wall upper beam 31 and front wall bottom end rail 32, before this
It is in stepped construction that crossbeam 31, which is placed, with front wall bottom end rail 32.The third is glued face 23 and is located at the 4th splicing 24 upper portion of face
It is glued with the front wall upper beam 31, it is horizontal under the 4th splicing 24 lower portion of face and the front wall which is glued face 23
Beam 32 connects.4th is glued the upside in face 24 and the front wall upper beam 31 splicing, lower portion and front wall bottom end rail 32
It is glued.
Fig. 4 is the diagrammatic cross-section of the assembling process of cabin longeron and connection structure, and assembling process is as shown in figure 4, elder generation
It is glued coating structure glue and dress Nian Jie with the right side of the cabin longeron assembly 10 on face 21 the first of the first connector 201
Match, the convex block 27 of 202 one end of the second connector is embedded into the hinge part 25 of first connector 201, inside the articulated section 25
And second be glued face 22 in advance be coated with structure glue, then, second connector 202 along Fig. 4 arrow direction rotate, directly
Second on to the second connector 202 is glued the left side adhesive asserably in face 22 and cabin longeron assembly 10, after assembly
State is as shown in Figure 5.
It should be appreciated that being also coated with structure glue inside the articulated section 25, there is abnormal sound after component assembly can be prevented.This
A connection piece 201 is same as the bonding plane that the second connector 202 fits to use structure glue bonding connection.
Then, the assembly with front wall crossbeam 30 is carried out, because front wall crossbeam 30 divides for front wall upper beam 31 and front wall bottom end rail
32, and the front wall upper beam 31 uses front and back stepped construction with front wall bottom end rail 32, can be realized after Nian Jie with connector 20
Solid connection.Specifically, first it is glued face 23 and the 4th in third and is glued coating structure glue on face 24, which is glued face 23 and is located at
4th is glued 24 upper portion of face is glued with the front wall upper beam 31, which is glued face 23 and is glued face 24 positioned at the 4th
Lower portion is connect with the front wall bottom end rail 32.4th is glued the upper end in face 24 and the front wall upper beam 31 splicing,
It is glued with front wall bottom end rail 32 lower portion.
It is thick shape fluid under room temperature, after being heated to certain temperature it should be noted that the structure glue used in the present invention
Kept for a period of time can fully cure, solidification temperature is relatively low, compared with welding without heat affected area, i.e. bonding region part
Intensity is unaffected, is equal to base material.Structure glue employed in the present embodiment is kept for 30 minutes after being heated to 190 °
Fully solidification.That is, part itself manufacture deviation and zero can be eliminated using structure glue thickness before structure glue is uncured
Rigging error between part achievees the purpose that improve the accuracy of manufacture.
In the present invention, cabin longeron assembly 10 and front wall crossbeam 30 are all made of the aluminium alloy extrusions of better performances, in proximate matter
Portion's crystal grain is thinner, thus has preferable intensity and rigidity, in addition, the cost of section mould for aluminium alloy is relatively low so that this hair
Bright die cost substantially reduces, while production efficiency also can be improved.
In conclusion the connection structure of the car engine room longeron and front wall crossbeam of the present invention, cabin longeron and front wall crossbeam
Using the aluminium alloy extrusions for possessing preferable rigidity and intensity, and section bar mold input cost is low, and production efficiency is high.The connection knot
Structure structure novel is unique, realizes that longeron and the three-dimensional of crossbeam connect, using structure glue technique for sticking, because of structure glue cold-adhered thermosetting
The characteristic of change so that for bonding region without heat affecting, the intensity after bonding solidification is unaffected.Meanwhile structure glue it is uncured it
The preceding assembling deviation eliminated using its glue thickness between part itself foozle and part, to improve the accuracy of manufacture.
Connection structure and embodiment of the specific case to the car engine room longeron and front wall crossbeam of the present invention are applied herein
It is expounded, the explanation of embodiment of above is merely used to help understand the method and its core concept of the present invention；Meanwhile it is right
In those of ordinary skill in the art, according to the thought of the present invention, change is had on specific embodiment and its application range
