Specific embodiment
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in Figure 1 it is a kind of shock-absorbing heat dissipation batteries of electric automobile based on negative Poisson material, is divided into each battery pack Six slots are equipped with a battery modules (1) in each slot.
The shock-absorbing scheme of this patent uses two-stage bradyseism measure, and first order bradyseism is negative poisson's ratio structure filling bring Shock-absorbing effect, second level bradyseism measure is to be fitted with 12 telescopic masts (2) in each slot, on each telescopic mast and cell wall Groove between be fitted with spring, two-stage bradyseism keeps bradyseism effect more excellent.
Heat-conducting plate layer (3) (aluminium alloy or heat conductive silica gel is followed successively by between battery modules (1) and battery pack housing from inside to outside Piece), negative poisson's ratio material filled layer (4) and carbon fiber board heat-sink shell (5), by negative poisson's ratio inside negative poisson's ratio material filled layer Cellular (6) composition.Wherein lead between heat-conducting plate (3), negative poisson's ratio material filled layer (4) and absorbing carbon fiber hot plate (5) each plate Gluing connection is crossed, carries out the fixation of vertical direction by the way of being inserted into groove with Housing Base (7) and top plate.
It is attached between each plate of battery pack housing surrounding using bolt (8) and nut (9), each plate of shell surrounding (10) In Top and bottom end are respectively opened up there are four threaded hole (11), are matched in Housing Base (7) and top plate with each plate of shell surrounding (10) Position open up and connected with bottom plate (7) by ball screw nut (13) through threaded hole (12), each plate of shell surrounding (10) and top plate It connects, centre is added with washer (14).
It is there is into water one end design at the top of circular water channel (15) and each plate that design, which has section, in each plate of shell surrounding (10) Mouth (16), the other end design in each board bottom portion has water outlet (17), so that heat dissipation be effectively performed.There is design on the outside of each plate Reinforcing rib (18) guarantees that cabinet can be protected to a certain extent when cabinet is hit.It is protruded among cover top plate and bottom plate (7) Portion is cased with rubber ring (19) to realize the sealing of cabinet.Two handles are fitted on each battery modules (1) (20), facilitate the taking-up of battery modules (1).
Embodiment
Battery case design parameter designed by this patent are as follows: outer case long 896mm, wide 489mm, high 297mm, each battery Mould group leader 230mm, wide 150mm, high 235mm.Each plate thickness 25mm of box plate, the thermally conductive plate thickness 5mm of aluminium alloy plate, negative poisson's ratio filling With a thickness of 15mm, carbon fiber board absorbs heat plate thickness for 10mm.Compare the parameter of negative poisson's ratio cellular shown in fig. 5, designed member Each parameter of born of the same parents is d=e=f=g=2mm, β=σ=79 °, θ=68 °.Negative poisson's ratio cellular thickness t=0.8mm, height h= 1mm。
When vehicle body due to road bumps, anxious acceleration and deceleration and when acutely shaking, two-stage shock sucking structure will be preferable in Battery case Play the role of bradyseism.Since the excellent energy-absorbing effect of negative poisson's ratio material can when Battery case is hit, squeezed The intracorporal battery modules of guard box to a certain extent.When battery generates amount of heat due to long-term work, aluminium alloy heat-conducting plate (or Person's heat-conducting silica gel sheet) heat is conducted by porous negative poisson's ratio packing material to absorbing carbon fiber hot plate.Coolant liquid is from shell The water inlet of plate upper end flows into, and the heat absorbed on absorbing carbon fiber hot plate is passed through shell plates lower end by shell intracorporal water channel Water outlet outflow is taken away, and significantly reduces the operating ambient temperature of battery, ensure that the normal work of battery.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.
