Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
In the figure, 1, a plastic shell; 2. a base plate; 3. a first reinforcing side plate; 4. a second reinforcing side plate; 5. installing an embedded part on the upper cover; 6. installing an embedded part on the vehicle body; 7. an electronic electrical bin; 8. and a battery compartment.
As shown in fig. 1-2, the utility model discloses a box under battery pack, including plastic casing 1, bottom plate 2, first enhancement curb plate 3 and second enhancement curb plate 4, electron electrical storage 7 and battery compartment 8.
The plastic shell 1 is of an integrated structure, and the internal structure of the plastic shell 1 is divided into an electronic electric bin and a battery bin. The plastic shell endows the box with basic structure and performance, and plays a role of coating the bottom plate 2, the first reinforcing side plate 3 and the second reinforcing side plate 4. The plastic shell material is a short fiber or long fiber reinforced thermoplastic composite material, such as PP GF 40. The electronic electrical bin 7 is used for installing components such as an electric control device and the like, and the battery bin 8 is used for installing the battery cell module. The surface of the lower box body of the battery pack is the surface of the bottom plate 2 and penetrates through the electronic electrical bin 7 and the battery bin 8, and the battery cell module is directly bonded on the bottom plate 2.
As shown in fig. 3, the bottom plate 2 is a light metal hollow plate, the hollow channel can be used for air cooling and heat dissipation, and the metal plate air duct exposed outside the housing can perform a heat dissipation function without adding a heat dissipation device.
The first reinforcing side plate 3 and/or the second reinforcing side plate 4 may be a metal plate, or may be a continuous fiber reinforced thermosetting or thermoplastic composite plate. The first reinforcing side plate 3 and/or the second reinforcing side plate 4 are/is provided with a part of through holes, and the through holes are mainly used for forming riveting structures with the plastic shell 1 in the forming process to fix the reinforcing plates. The first reinforcing side plate and the second reinforcing side plate 4 are used for bearing expansion force caused by cell expansion. The first reinforcing side plate 3 is rectangular, is arranged on one side of the battery bin 8 far away from the electronic and electric bin 7, and has the same size with the first reinforcing side plate, and the second reinforcing side plate 4 is arranged on the periphery of the electronic and electric bin 7 except one side of the battery bin 8.
The utility model discloses a battery package lower box body is still including establishing upper cover installation built-in fitting 5 on plastic casing 1 and establishing the automobile body installation built-in fitting 6 in plastic casing 1 both sides.
