  • Using elastic averaging for alignment of battery stack, fuel cell stack, or other vehicle assembly
    Patent number: 9812684
    Abstract: An assembly for a vehicle includes a first member including a plurality of elastically deformable locating protrusions extending outward, and a second member defining a cavity extending inward and including a plurality of elastically deformable compression features disposed within the cavity. The locating protrusions of the first member are disposed within the cavity of the second member in press fit engagement with the compression features of the second member to secure the first member relative to the second member. The average of the elastic deformation between all of the locating protrusions of the first member and all of the compression features of the second member precisely aligns the first member relative to the second member. The assembly may include but is not limited to a multiple unit battery pack, a multiple unit fuel cell pack, a dashboard assembly or adjoining body panels.
