Abstract: A vehicle body reinforcing structure installed in a vehicle including a vehicle body and a battery pack provided in the vehicle body includes a first reinforcing member including at least a cross connection portion; and a second reinforcing member including at least a reinforcing portion arranged to extend along a longitudinal direction of a side surface of the battery pack, wherein both the first reinforcing member and the second reinforcing member are arranged along the longitudinal direction of the side surface of the battery pack, and the two ends of the first reinforcing member and the second reinforcing member are connected to the vehicle body respectively.

Abstract: A battery protection device installed in a vehicle, wherein the vehicle includes a vehicle body and a battery pack arranged inside the vehicle body is provided, wherein the battery protection device includes a vehicle body reinforcing structure provided to extend along a length direction of either side surface of the battery pack, two ends of the vehicle body reinforcing structure are fixed to the vehicle body respectively; and a battery protection structure that extends along the length direction of either side surface of the battery pack and is installed on a side of the vehicle body reinforcing structure far from the battery pack.

Abstract: The exemplary embodiments generally relate to a device for reinforcing an automotive roof assembly. Some embodiments include a stiffening member for attaching to a cross member of an automotive roof assembly. The stiffening member may have a plurality of supports for providing additional stiffness in longitudinal, lateral, and/or vertical directions. Some embodiments relate to methods of making and/or using the device.

Abstract: A frame for a speaker device includes a magnetic circuit housing unit which houses a magnetic circuit, an annular outer peripheral portion which is arranged on an outer side of the magnetic circuit housing unit, and plural arm portions which connect the magnetic circuit housing unit and the outer peripheral portion. The plural arm portions form such plural bridges that a pair of the arm portions are linearly positioned to connect two parts of the outer peripheral portion, and each of the bridges does not pass through a center of the outer peripheral portion.

Abstract: A rear body structure of a vehicle is disclosed which comprises a pair of right and left rear wheel houses and a reinforcing cross member extending between the rear wheel houses, wherein the cross member is comprised of a lower cross member located below a floor panel of the vehicle and an upper cross member located above the floor panel, and wherein the lower cross member, the floor panel and the upper cross member are weld connected together. As a result, the rigidity of the cross member is increased, whereby drumming arising from the vibrations transmitted from suspensions to areas about a bulkhead of the rear body structure may be avoided, and the time required for luggage loading and unloading operations with respect to a luggage compartment may be shortened. Since the upper cross member is designed to have a small height, it also becomes possible to load long articles spanning from the luggage compartment to a rear part of a passenger compartment.
