Abstract:
1. A vehicle structure comprising: a longitudinal structural element at each of its side edges; at least two essentially horizontal shells that are superposed so as to form a housing between them, each of said at least two essentially horizontal shells being connected to at least one of the two longitudinal structural elements; at least one battery component containing at least one energy storage unit arranged in said housing; and at least one fastener element comprising a fastener body, a resilient means and a plate, wherein said fastener body passes through said at least two essentially horizontal shells, said resilient means and said plate, wherein said plate bears against said at least one battery component and said resilient means bears against said plate and at least one of said at least two essentially horizontal shells so as to exert a compressive force on said at least one battery component, said at least one fastener element securing said at least two essentially horizontal shells together and being arranged in such a manner that said at least one battery component is in compression in the shell-superposition direction, corresponding to a vertical direction, wherein at least one of said at least one fastener element is situated between adjacent energy storage units, wherein said resilient means is a spring washer; a portion or surface of one of said at least two essentially horizontal shells being generally parallel to a portion or surface of the other of said at least two essentially horizontal shells with said at least one battery component being situated therebetween; said at least one fastener comprising a fastener body that passes through and is in contact with said portions or surfaces of said at least two essentially horizontal shells so that when said at least one fastener element is tightened, said at least two essentially horizontal shells become fastened together and a force is transferred to a member which applies a compressive force to said at least one battery component.
