Embodiment 1

[0049]This embodiment discloses a battery system connection sealing mechanism, such asfigure 1 As shown, it includes a connecting pillar 10, a first sealing ring 30, a second sealing ring 50, a first locking member 20 and a second locking member 40, wherein the connecting pillar 10 is used to connect the underbody 70 and the battery pack box. The battery pack case is used to load battery packs. A battery pack composed of several batteries is arranged in the battery pack case. The battery pack case includes a lower tray 601 and an upper cover 602. The connecting pillar 10 and the lower tray 601 are welded and fixed Together, the connecting pillar 10 will not be separated from the lower tray 601. Such asfigure 2 As shown, the upper part of the connecting pillar 10 is a connecting portion 102, and a limiting portion 101 is provided on the outer periphery of the connecting portion 102. In this embodiment, the limiting portion 101 is a bump disposed around the outer peripheral wall of th...

Embodiment 2

[0056]This embodiment discloses a vehicle body. The vehicle body includes the battery system connection and sealing mechanism in Embodiment 1, a vehicle body floor 70 and a battery pack box. The battery pack box is used to place a battery pack, specifically, the battery pack is arranged On the lower tray 601. In this embodiment, the vehicle body floor 70 includes a vehicle body cross member and a vehicle body longitudinal member, and the lower tray 601 includes a pallet cross member and a pallet longitudinal member. The pallet beams or the pallet stringers are welded and fixed together.

[0057]The connecting pillar 10 is connected to the vehicle body cross beam or the vehicle body longitudinal beam to improve the connection strength between the connecting pillar 10 and the vehicle body floor 70 and avoid the vehicle body floor 70 from being deformed by force. In addition, on the main bearing structure of the connecting pillar 10 connecting the vehicle body floor 70, the vehicle body f...

Embodiment 3

[0059]This embodiment discloses a car, which includes the car body in the second embodiment, wherein the car body is applied to a pure electric car, a plug-in hybrid electric car, and a range-extended car with a power battery system arranged outside the vehicle.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a battery system connection and sealing mechanism, a vehicle body and an automobile. Background technique [0002] At present, against the background of the slowdown in the growth rate of China's auto market, the rapid growth of sales of new energy vehicles has become a bright spot in the auto market. Judging from the sales data of the first two months of this year, new energy vehicles are becoming the main driving force for the development of the domestic auto market. However, with the increase of market users, the existing problems become more and more obvious. [0003] Compared with traditional fuel vehicles that have been developed for more than a hundred years, new energy vehicles are still in the initial stage of development. Problems such as short cruising range, long charging time, and insufficient safety of power batteries all restrict consumers' purchase...
