On, in this way, the positive pole of cell 22 is connected by Flexible Connector 248 and the positive pole for confluxing circuit board 24 layer 242 that confluxes
Connect.The shell (i.e. the negative pole of monomer) of cell 22 is converged by the sheet metal (not shown) being contained in cellular unit with negative pole
Fluid layer 244 is electrically connected with.The circuit board 24 that confluxes is placed on the lower cover 14, i.e., the described circuit board 24 that confluxes is placed in the lower cover
On the top plate 142 of plate 14, contacted with the top plate 142, specifically, the positive pole confluxes, layer 242 contacts with the top plate 142.
The intermediate plate 34 is positioned on the top surface 164 of the honeycomb installation structure 16 again, the negative pole end 224 of all cells 22
It is generally aligned in the same plane and towards the intermediate plate 34, the negative pole end of all cells 22 passes through the perforation of the intermediate plate 34
342, heat-conducting plate 32 is arranged on the intermediate plate 34 again, the negative pole end of all cells 22 contacts with heat-conducting plate 32,
I.e. honeycomb installation structure 16 and institute's heat-conducting plate 32 are arranged at two opposite surfaces of the central dividing plate 34.Finally by upper cover plate
12 are arranged at the heat-conducting plate 32.
As shown in Fig. 2 producing heat when cell 22 works, negative pole end 224 transfers heat to the heat-conducting plate
32, on the one hand the heat that heat-conducting plate 32 absorbs can be conducted by the upper cover plate 12 of longitudinal direction, on the other hand can be internal logical
The heat conducting pipe 322 for having cold air conducts (conduction orientation of heat is as indicated by the arrow).
The lower cover 14 of electric automobile chassis structure 100 provided by the invention includes top plate 142, bottom plate 144 and positioned at institute
The cushion 146 between top plate 142 and the bottom plate 144 is stated, cushion 146 improves the energy-absorbing damping effect of the lower cover 14
Fruit, and the top plate 142 and the light weight of the bottom plate 144, intensity are high, have certain anti-corrosion capability and anti-penetration ability.
The present invention is not restricted to described in specification and embodiment, therefore for the personnel of familiar field
Additional advantage and modification is easily achieved, therefore in the essence of the universal limited without departing substantially from claim and equivalency range
In the case of refreshing and scope, the present invention is not limited to specific details, representational equipment and shown here as the diagram with description
Example.
