The invention discloses a lower vehicle body of a vehicle body structure, a dismounting method thereof, the vehicle body structure and a vehicle. The lower vehicle body comprises a front cabin assembly, a battery assembly and a rear floor assembly, the front portion of the battery assembly is detachably matched with the front cabin assembly, and the rear portion of the battery assembly is detachably matched with the rear floor assembly. The battery assembly is suitable for being independently and detachably matched with an upper vehicle body of the vehicle body structure relative to the front cabin assembly and the rear floor assembly. According to the technical scheme, the battery assembly is integrated on the lower vehicle body, the number of parts can be reduced, and the total weight of the lower vehicle body is reduced. In addition, the battery assembly can be independently detached relative to the front cabin assembly and the rear floor assembly, when the battery assembly needs to be maintained and replaced, only the battery assembly needs to be detached, and the front cabin assembly and the rear floor assembly do not need to be detached together, so that the detaching convenience is greatly improved, the replacement and maintenance efficiency is improved, and the user experience is improved.

    一种车身结构的下车体及其拆装方法、车身结构和车辆。下车体包括前舱总成、电池总成和后地板总成,所述电池总成的前部与所述前舱总成可拆卸配合且后部与所述后地板总成可拆卸配合,所述电池总成适于相对于所述前舱总成和所述后地板总成可单独拆卸地与所述车身结构的上车体配合。在上述技术方案中,电池总成集成于下车体,有利于减少零部件数量,降低下车体的总重量。并且电池总成相对于前舱总成和后地板总成可独立拆卸,在电池总成需要维修和更换时仅需拆卸电池总成,不需要将前舱总成和后地板总成一起拆下,大大提高了拆装便捷性,有利于提高更换维修效率,提高用户体验。
