1. A bodyshell structure for an electrically driveable motor vehicle, comprising:
a ventilation channel formed by a plurality of structural components that are connected to one another and delimit respective cavities, wherein the ventilation channel has at least one inlet opening for inflow of a venting gas that emerges from a drive battery of the motor vehicle in an event of a thermal event and has at least one outlet opening via which the venting gas is dischargeable into a surrounding of the motor vehicle; and
a venting gas treatment device disposed inside the ventilation channel, wherein the venting gas and/or particles entrained with the venting gas is treatable by the venting gas treatment device;
wherein the venting gas treatment device has a contouring or labyrinth path for extending a flow path of the venting gas through the ventilation channel and/or for collecting the particles entrained with the venting gas.
