Background
The power battery for the new energy automobile mainly comprises a plurality of battery modules which are arranged in a battery pack and provide power sources for the automobile, and the proportion of the weight of the modules in the battery pack needs to be reduced along with the continuous improvement of the requirement on high energy density of the battery pack; whole car is at the in-process of traveling, if during collision and the extrusion condition, for avoiding electric core to receive the extrusion and weeping, fire and explosion, it has sufficient mechanical strength to need the module.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a high strength casting aluminum alloy module end plate can reduce the weight of battery module and promote the structural strength of battery module.
The technical scheme of the utility model is that:
the utility model provides a high strength casting aluminum alloy module end plate, is including the aluminum alloy end plate main part of slotted shell form, and the top of aluminum alloy end plate main part is provided with two hoistingholes, two positive negative poles and draws forth mouth and connector mouth, and two corners that aluminum alloy end plate main part is located the top are provided with the bolt installation step that downward punching press formed, and two corners that aluminum alloy end plate main part is located the bottom are provided with the bolt installation step that upward punching press formed, and four bolt installation step departments all are provided with the bolt mounting hole, the inner wall of aluminum alloy end plate main part on be provided with a plurality of recess strengthening ribs that are cellular range.
The connector opening is of a U-shaped groove structure, and the bottom surface of the groove is an arc-shaped surface.
The connector opening is positioned between the two hoisting holes, and the two hoisting holes are positioned between the two positive and negative leading-out openings.
And transverse ribs are fixed on the inner wall of the aluminum alloy end plate main body and positioned between the two bolt mounting steps corresponding to each other up and down.
The bottom surface of the inner wall of the aluminum alloy end plate main body is an outward inclined slope surface.
The utility model has the advantages that:
(1) the end plate main body of the utility model is cast by aluminum alloy, which is convenient for mass production of battery modules;
(2) the bolt mounting step of the utility model can be cast and stamped to form different height structures according to the height of the battery pack mounting amount, so as to be convenient for mounting in battery packs of various sizes;
(3) the positive and negative electrode lead-out holes of the utility model are used for leading out the total positive and negative copper bars after the electric cores are connected in series and in parallel;
(4) the two hoisting holes of the utility model are used for hoisting the battery module in the battery pack, thereby facilitating the mechanical installation and disassembly;
(5) the utility model discloses a connector mouth mainly used control terminal connects the spigot joint, and U type notch shaping plays the effort when balanced battery module tip receives the extrusion post extrusion between two hole for hoist, and U type notch has avoided the production of breach stress concentration, has reduced the cast member and has torn the risk in the extrusion process of battery module tip;
(6) the groove reinforcing ribs arranged in a honeycomb shape in the end plate main body of the utility model reduce the weight of the end plate and reduce the casting defects due to the uniform thickness when casting, and the groove reinforcing ribs distributed vertically and horizontally enhance the bending rigidity of the end plate;
(7) the utility model discloses the inside horizontal rib of end plate main part and the design of bottom slope have alleviateed the weight of casting end plate and have improved its structural strength who resists the extrusion of battery module tip.
The utility model discloses both can satisfy the installation design requirement of battery module, and alleviateed the weight of end plate, can promote the mechanical strength of battery module end plate again.
