Hot spot as automotive field research.The generally existing problem in electric car field is accumulator of electric car course continuation mileage at present
Limited, which has limited the popularization and application of electric car.
On the vehicle body of the aluminium alloy extrusions of electric vehicle, subframe plays an important role, and requires installation machinery, power thereon
Component, such as lower swing arm, turning machine mechanical structure will also install a large amount of high voltage electric equipment, such as controller, motor, secondary
Vehicle frame requires structural stability, connection reliable.Important component of the overlap joint crossbeam as Rear secondary frame for vehicle afterwards, therefore, to rear pair
The rear overlap joint crossbeam welded on vehicle frame proposes high requirement, it is to be ensured that security performance is optimal while light-weight, mesh
Before, there are no corresponding technologies to be able to satisfy above-mentioned requirements.
Utility model content
It is horizontal purpose of the utility model is to overcome the above-mentioned shortcomings and provide being overlapped after a kind of automobile that security performance is high
Beam manufactured using hollow aluminium alloy extrusions, it is ensured that security performance is optimal while light-weight, meets installation, connection
It is required that.
Purpose of the utility model is realized as follows:
Crossbeam is overlapped after a kind of automobile that security performance is high, the second L-type side of the first L-type side and outside including inside,
First L-type side end passes through the first linkage section respectively with the second L-type side end and the second linkage section connects, the first L
The vertical section of second L-type side of horizontal segment horizontal direction on type side extends to form third linkage section, the first linkage section, the second linkage section,
First L-type side and the second L-type side are divided into the first compression chamber, the second compression chamber and third by third linkage section and the 4th linkage section
Compression chamber.
Preferably, the first compression chamber, the second compression chamber and third compression chamber are rectangle of the quadrangle with circular arc.Respectively by
Pressure chamber alleviates overall weight, while ensure that whole interior intensity, and each compression chamber stability is strong, proposes general safety performance
It is high.
Preferably, the first compression chamber and the second compression chamber shape are identical.
Preferably, the horizontal segment, the first linkage section of second L-type side and the thickness of the second linkage section are identical.
Preferably, the vertical section of second L-type side, the first L-type side are identical with third linkage section thickness.
Preferably, the horizontal segment thickness of second L-type side is greater than the vertical section thickness of second L-type side.It ensure that
The intensity of whole bottom and end, security performance are optimal.
Preferably, the thickness of the 4th linkage section is greater than the thickness of the first linkage section.Light-weighted while guaranteeing whole
The intensity of body.
The beneficial effects of the utility model are:
The utility model is manufactured using hollow aluminium alloy extrusions, it is ensured that and security performance is optimal while light-weight,
The requirement for meeting installation, connection, is conducive to electric car lightweight, can effectively extend electric car course continuation mileage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: the first L-type side 1；Second L-type side 2；First linkage section 3；Second linkage section 4；Third linkage section 5；4th connects
Connect section 6；First compression chamber 7；Second compression chamber 8；Third compression chamber 9.
Specific embodiment
Referring to Fig. 1, the utility model relates to overlap crossbeam after a kind of automobile that security performance is high, the first L including inside
Second L-type side 2 on type side 1 and outside, 1 end of the first L-type side and 2 end of the second L-type side pass through the first linkage section 3 respectively
It is connected with the second linkage section 4, the vertical section of the second L-type side of horizontal segment horizontal direction 2 of first L-type side 1 extends to form third
Linkage section 5, the first linkage section 3, the second linkage section 4, third linkage section 5 and the 4th linkage section 6 are by the first L-type side 1 and the second L-type
Side 2 is divided into the first compression chamber 7, the second compression chamber 8 and third compression chamber 9.
The first compression chamber 7, the second compression chamber 8 and third compression chamber 9 are rectangle of the quadrangle with circular arc.Each compression chamber
Overall weight is alleviated, while ensure that whole interior intensity, each compression chamber stability is strong, improves general safety performance.
The first compression chamber 7 is identical with 8 shape of the second compression chamber.
The horizontal segment of second L-type side 2, the first linkage section 3 are identical with the thickness of the second linkage section 4.
The vertical section of second L-type side 2, the first L-type side 1 are identical with 5 thickness of third linkage section.
The horizontal segment thickness of second L-type side 2 is greater than the vertical section thickness of second L-type side 2.It ensure that integral bottom
The intensity in portion and end, security performance are optimal.
The thickness of 4th linkage section 6 is greater than the thickness of the first linkage section 3.Light-weighted while guaranteeing whole strong
