Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
It is as shown in Figure 1 modular structure explosive decomposition figure, by battery core main body 1, plastic frame 1, heat conductive insulating pad 1,
Liquid cooling plate 1, BMS5, plastic frame 26, heat conductive insulating pad 27, liquid cooling plate 28, mould group end plate 1, mould group end plate 2 10,
Die set top fixing piece 11 and mould group bottom nozzle mounts 12 form.
Battery core main body 1 is made of battery core and framework composition, can increase the heat between heat insulating mattress barrier battery core between battery core
Amount transmitting, optimizes the temperature difference between mould group, also has certain relaxation effect to battery thermal runaway.It can be selected according to body structure
Different battery core quantity, battery core quantity is higher, and light weight degree is higher.Plastic frame 1 and plastic frame 26 with support electricity
It is series-parallel between core, and the positive electrode and negative electrode of mould group are drawn, for the connection of system, pass through material borehole in plastic frame
And reinforcing rib design, loss of weight simultaneously guarantee plastic part intensity.Heat conductive insulating pad 1 and heat conductive insulating pad 27 are thermally conductive by cost
Coefficient, the class of insulation and density are comprehensive to be determined.Liquid cooling plate 1 and liquid cooling plate 28 can be brazed by profile, inflation, punching press
The moulding process machine-shapings such as plate soldering.BMS5 can be placed on liquid cooling plate, guarantee that the data acquisition of mould group is accurate and reliable.
Die set top fixing piece 11 and mould group bottom nozzle mounts 12 select High-strength light-weight metal material, such as aluminium alloy, by subtracting
Repeated hole carries out loss of weight appropriate, die set top fixing piece 11, mould group bottom nozzle mounts 12 and mould group end plate 1 to structural member,
Mould group end plate 2 10 plays the role of fixed entire battery modules, needs to guarantee by it stability of mould group.
For mould group end plate 1, mould group end plate 2 10 and die set top fixing piece 11 and mould group bottom nozzle mounts 12 it
Between connection, can be by the different forms such as welding or being bonded.A kind of method for providing laser welding such as Fig. 2.Mould group end
Plate 14 is Extrusion Process of Aluminum Alloy Profile molding, and intensity is high, forms simply relative to structures such as cast aluminiums, there is lightweight effect.Due to profile
Hollow part is unfavorable for welding, so milling out corresponding N-shaped groove a by the secondary operation to profile.N-shaped block structure 15 passes through
N-shaped block structure 15 is placed in N-shaped groove a by extrusion forming.After covering die set top fixed plate 13, pass through the flange of fixing piece
Structure c guarantees that N-shaped block structure 15 is not fallen out, and Laser Welding company will be carried out between N-shaped block structure 15 and die set top fixed plate 13
It connects.15 outside of N-shaped block structure is invisible when due to welding, can be in die set top fixed plate 13 to guarantee positioning when welding
The determination for illustrating the distinguishing marks such as hole b to enter welding region is welded in upper setting.
As shown in figure 3, liquid cooling plate 17 is fixed on plastic frame by plastic buckle 16, the use for reducing bolt reduces matter
Amount.And can dismantle, fixed point is more, fixed reliable.BMS fixed column f passes through welding or the main body for being adhesively fixed on liquid cooling plate 17
On, for fixing BMS5.Liquid cooling plate 17 is equipped with inlet d and liquid outlet e, and inside can use series connection, parallel connection or mixed connection, at
Type technique can choose extruding soldering, punching press soldering, inflation etc..
