Description
Technical field
The present invention relates to a kind of electronic compound girder construction of commercial vehicle body bottom, belong to new-energy automobile body construction technology
Field.
Background technology
With the continuous social and economic development, people's living standard improves constantly, the continuous adjustment of automobile industry, and automobile is light
Quantify, electrified, intelligent, interconnected trend grows to even greater heights, people are to automobile comfortableness in the process of moving and vapour
Car traveling operability, security it is also proposed higher requirement.
For electronic commercial vehicle when suffering from accident, body structure plays great role to the safety of occupant.Current market
The vehicle body framework construction of upper commerial vehicle is difficult to take into account overall construction intensity and vehicle body deadweight problem.Electronic commercial vehicle is compared with traditional vehicle
For, the especially quality weight of bottom motors and battery case adds body bottom load, under the long term of the load
Deformation of Body Framework can be caused, has a strong impact on driving safety.
The content of the invention
The technical problem to be solved in the present invention is：A kind of compound girder construction of electronic commercial vehicle body bottom and connection side are provided
Method, strengthens the intensity of body bottom, and then avoids the purpose of Deformation of Body Framework, ensures driving safety.
The purpose of the present invention is achieved through the following technical solutions：
A kind of compound girder construction of electronic commercial vehicle body bottom and connection method, including underbody, in underbody
It is left and right to be provided at both ends with side plate, two first buttress braces, every first buttress brace are arranged at intervals with the lower surface of underbody
Left and right both ends be connected respectively with side plate, be also arranged at intervals with two second buttress braces in the lower surface of underbody, second plus
Brutal and the first buttress brace are set in " well " font, and the both ends of every second buttress brace and the end vertical of the first buttress brace connect
Connect, the lower surface of the underbody, the first buttress brace and the second buttress brace are collectively forming for placing battery case or motor
Accommodating cavity.
Preferably, the arched structure of the first buttress brace, the height at both ends are more than the height of center section.Using arch
Structure, while improving the first reinforcement beam strength while weight is reduced, reach and take into account overall construction intensity and avoid car
Body deadweight causes framework deformation problem.
A kind of connection method of the electronic compound girder construction of commercial vehicle body bottom, the both ends of every second buttress brace penetrate
The end of one buttress brace is simultaneously connected using welding manner, and the top surface of the second buttress brace mutually welds with the lower surface of underbody.The
Two buttress braces are easy to welding after penetrating, and ensure the reliability of the first buttress brace and the welding of the second buttress brace.
Further, the left and right both ends of every first buttress brace are connected with side plate using welding manner respectively, and first strengthens
The top surface of beam mutually welds with the lower surface of underbody.
By using above-mentioned technical proposal, beneficial effects of the present invention are：It is in by the first buttress brace and the second buttress brace
" well " font is arranged on the lower surface of underbody, and the both ends of every first buttress brace are connected with side plate respectively, and first adds
Brutal and the second buttress brace intersect installation site of the quadrilateral area surrounded as battery case or motor two-by-two, so that
Uniform load caused by battery case or motor is distributed on underbody.In addition, side plate, the first buttress brace and second are strengthened
The closed-loop construct that beam is formed significantly increases the intensity of vehicle body increase underbody, effectively avoids underbody from deforming,
And then the purpose of Deformation of Body Framework is avoided, ensure driving safety.

Description of reference numerals：1st, underbody；2nd, side plate；3rd, the first buttress brace；4th, the second buttress brace；5th, accommodating cavity.
Embodiment
Below in conjunction with the accompanying drawings and invention is described further specific embodiment：
As shown in drawings, a kind of compound girder construction of electronic commercial vehicle body bottom and connection method, including underbody 1,
Left and right in underbody 1 is provided at both ends with side plate 2, and two first buttress braces are arranged at intervals with the lower surface of underbody 1
3, the left and right both ends of every first buttress brace 3 are connected with side plate 2 respectively, and two are also arranged at intervals with the lower surface of underbody 1
The second buttress brace of root 4, the second buttress brace 4 and the first buttress brace 3 in " well " font set, the both ends of every second buttress brace 4 with
The end vertical connection of first buttress brace 3, the lower surface of the underbody 1, the first buttress brace 3 and the second buttress brace 4 are common
With the accommodating cavity 5 formed for placing battery case or motor.
In the present embodiment, the 3 arched structure of the first buttress brace, the height at both ends are more than the height of center section.
Further, the both ends of every second buttress brace 4 are penetrated the end of the first buttress brace 3 and connected using welding manner
Connect, the top surface of the second buttress brace 4 mutually welds with the lower surface of underbody 1.The left and right both ends difference of every first buttress brace 3
It is connected with side plate 2 using welding manner, the top surface of the first buttress brace 3 mutually welds with the lower surface of underbody 1.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
