Description
Technical field
The utility model relates to the battery systems of electric car, specifically, being related to for electric automobile battery box body
Border structure.
Background technique
Country advocates and pushes energetically the development of New Energy Industry at present, wherein new-energy automobile, especially electric car,
An important directions as new-energy automobile industry development.Electric car is using vehicle power supply as power, with motor driven vehicle
Wheel traveling, a kind of new-energy automobile having fewer environmental impacts.Vehicle power supply is battery, and the safety of battery is particularly important.
Existing electric automobile battery box is in order to realize being stably connected with for battery pack and car body, the excessively complicated connection of design
Structure and connector；Or outer attached hangers causes integrated connection intensity inadequate；Connection type is common welding between component, even
The commissure intensity of binding structure is inadequate, is easy to cause Joint failure.
Utility model content
Technical problem to be solved in the utility model is that overcome the deficiencies of the prior art and provide a kind of structure simple, whole
Body lightweight, structural strength is high, and the connection with car body is reliably used for the border structure of electric automobile battery box body.
The utility model solve its technical problem the technical solution adopted is that,
For the border structure of electric automobile battery box body, which is whole frame, is installed on Battery case
On bottom plate side, whole frame is made of transverse frame and longitudinal edge frame, and the transverse frame is consistent with the cross sectional shape of the longitudinal edge frame,
It is interconnected to form as square structure.Transverse frame is equipped with two, respectively the first transverse frame and the second transverse frame.Longitudinal edge frame is equipped with
Two, respectively the first longitudinal edge frame and the second longitudinal edge frame.The inner side and outer side of first longitudinal edge frame and the second longitudinal edge frame is respectively equipped with
Stiffening plate, the length of stiffening plate are less than the length of transverse frame, and outer stiffening plate is longer than inside stiffening plate, will be by longitudinal edge frame and horizontal edge
The region of frame composition is divided into region I and region II.Prolonged by two along the midpoint of frame one side in the section of transverse frame and longitudinal edge frame
The both sides for extending to the upper and lower side of opposite side are divided into 3 triangular structures.The quantity of transverse frame and longitudinal edge frame distinguishes >=4.
The outside of whole frame is equipped with equally distributed hangers.
Further, the hangers is stud structure, is symmetrically disposed on longitudinal edge outer frame side, and each longitudinal edge frame is equipped with >=1
A hangers.
Further, the thickness of the whole frame is 3 mm.
The utility model has the positive effect that: transverse frame and longitudinal edge frame cross sectional shape are hollow triangle, are both improved
Frame intensity, when vehicle is collided, Battery case is unlikely to deform, and has good protection function to the battery in battery case
Can, and make Battery case entirety lightweight；The design of hangers improves partial structurtes intensity.
Detailed description of the invention
Fig. 1 is the three dimensional structure diagram of the utility model embodiment；
Fig. 2 is partial enlargement diagram at the A of Fig. 1；
Fig. 3 is the structural schematic diagram of hangers in embodiment illustrated in fig. 1.
In figure: 1. whole frames, 11. transverse frames, 12. longitudinal edge frames, 111. first transverse frames, 112. second transverse frames,
113. third transverse frame, 114. the 4th transverse frames, 121. first longitudinal edge frames, 122. second longitudinal edge frames, 123. third longitudinal edge frames,
124. the 4th longitudinal edge frame, 2. hangers.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail.
Embodiment
As shown in FIG. 1 to FIG. 2, the present embodiment includes the whole frame 1 being installed on Battery case bottom plate side, whole side
Frame 1 is made of transverse frame 11 and longitudinal edge frame 12, and transverse frame 11 is consistent with the cross sectional shape of longitudinal edge frame 12, and is hollow triangle knot
The outside of structure, the entirety frame 1 is equipped with equally distributed hangers 2.
Transverse frame 11 is equipped with two, respectively the first transverse frame 111, the second transverse frame 112.
Longitudinal edge frame 12 is equipped with two, respectively the first longitudinal edge frame 121, the second longitudinal edge frame 122.
First longitudinal edge frame 121,122 inner side and outer side of the second longitudinal edge frame are respectively equipped with stiffening plate, and the length of stiffening plate is less than
The length of transverse frame, outer stiffening plate be longer than inside stiffening plate, by the region being made of longitudinal edge frame and transverse frame be divided into region I and
Region II.The setting of stiffening plate can make the intensity and rigidity reinforced of frame, and the width of region II increases, and be convenient for reasonable cloth
Office's box baseplate.
It is connected by the way of welding between transverse frame 11 and longitudinal edge frame 12, this structure can be designed so that transverse frame 11
An entirety is formed with longitudinal edge frame 12, to guarantee the intensity of connection, and round-corner transition structure is eliminated, increases while simplifying technique
Strong intensity.
As shown in figure 3, the outside of longitudinal edge frame 12 is equipped with hangers 2, the frame hangers at the II of region is arranged on external reinforcing plate for car,
Hangers 2 is symmetrically disposed on 12 outside of longitudinal edge frame, every side 4；Hangers 2 is weldingly connected with longitudinal edge frame 12 by agitating friction, is hung
Ear 2 uses stud structure, and to improve the intensity of hangers part, the thickness of whole frame 1 is 3 mm, the master of whole frame 1
Body uses the highest triangular structure of bending strength according to topology optimization design, transverse frame 11 and 12 section of longitudinal edge frame, rectangular
Transverse frame, longitudinal edge frame section are divided into 3 by the both sides for the upper and lower side that two midpoints along frame one side extend to opposite side
A triangular structure proof strength and can reach light-weighted purpose.
The inside of whole frame 1 is welded on the outside of Battery case bottom plate, it is ensured that with automobile chassis connection reliability
Under the premise of, the length of hangers 2 has been shortened, the weight of material is reduced.
