Fig. 2 is the structural representation of end plate;
Fig. 3 is the structural representation of module side plate;
Fig. 4 is the sectional drawing after the utility model installation.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 2 to Fig. 4, power battery module fastening structure provided by the utility model, it includes two Hes of end plate 200 Two module side plates 300.
End plate 200, it is separately positioned on the left and right ends of power battery module 400, and it is to be used to protect electrokinetic cell mould 400 left and right ends of group.
End plate 200 includes the bottom panel 210 of a square shape, and side plate 220 is respectively equipped with 210 each side of bottom panel, Side plate 220 is rectangular-shaped, and each side plate 220 coordinates with bottom panel 210 can form a ringent power battery module end plate, by It is opening sandwich type element in power battery module end plate, is so greatly improved the integral heat sink performance of power battery module end plate.
It is additionally provided with several the first heat emission holes 211 on bottom panel 210, the heat in power battery module can pass through first Heat emission hole 211 directly disperses.
Several radiating reinforcing plates 212 are provided with the lateral surface of bottom panel 210, radiating reinforcing plate 212 is used for into one Step improves the heat dispersion of bottom panel 210.
Radiating reinforcing plate 212 is rectangle, and volume is identical with side plate 220, and radiating reinforcing plate 212 can improve electrokinetic cell mould The integrated support intensity of group end plate, first can be with side plate 220 and scattered when having external component and power battery module end plate to collide Hot reinforcing plate 212 is contacted, and side plate 220 and radiating reinforcing plate 212 can be supported to bottom panel 210 together, prevent bottom panel 210 damages.
Heat emission hole also is provided with radiating reinforcing plate 212, heat emission hole is also used for improving radiating efficiency.
Several screws 221 are respectively equipped with the side plate 220 positioned at the left and right sides of bottom panel 210, bottom panel 210 passes through Screw 221 can be detachably connected with module side plate 300.
Module side plate 300, it is arranged on the rear and front end of power battery module 400, and it is to be used to protect electrokinetic cell mould The rear and front end of group 400.
