Embodiment 1

[0049] This example discloses a battery system connection sealing mechanism, such as figure 1 As shown, it includes a connecting strut 10, a first seal ring 30, a second seal ring 50, a first locking member 20, and a second locking member 40, wherein the connecting strut 10 is used to connect the body bottom plate 70 and a battery pack body. The battery pack is used to load the battery pack, and the battery pack consisting of several batteries is disposed in the battery pack body, wherein the battery pack body includes a lower tray 601 and a cap 602, wherein the connecting strut 10 and the lower tray 601 welding is fixed. Together, the connection strut 10 will not be separated from the lower tray 601. like figure 2 As shown, the upper portion of the connecting strut 10 is a connecting portion 102, and the finite portion 101 is provided at the outer circumference of the connecting portion 102, and the limit portion 101 is surrounded by a bump disposed outside the outer peripheral s...

Embodiment 2

[0056] This example discloses a vehicle body including the battery system connection sealing mechanism, body bottom plate 70 and battery pack body in Example 1, wherein the battery pack is used to place a battery pack, specifically, battery pack settings. On the lower tray 601. In the present embodiment, the body bottom plate 70 includes a vehicle body beam and a vehicle body stringer, and the lower tray 601 includes a tray beam and a tray stringer, wherein the upper end of the connecting strut 10 and the vehicle body beam or the body stringer are fixed together, the lower end and The tray beam or tray strip is welded together.

[0057] The connecting strut 10 enhances the connection strength between the connecting struts 10 and the body bottom plate 70 by connecting the body beam or the vehicle body stringer to avoid the force deformed by the body bottom plate 70. Further, the body bottom plate 70 is capable of carrying the battery pack weight on the main body support structure o...

Embodiment 3

[0059] This example discloses a car that includes a vehicle body in Example 2, wherein the body is applied to a power storage battery system, a pure electric vehicle disposed outside the vehicle, plug-in hybrid vehicle and a surrender vehicle.

Abstract

The application discloses a battery system connecting sealing mechanism, a vehicle body and an automobile, including a connecting pillar, a first sealing ring, a second sealing ring, a first locking member and a second locking member; the connecting pillar is used for connecting the vehicle body The bottom plate and the battery pack box body, the battery pack box body includes a lower tray and an upper cover, the connecting pillar is fixedly connected to the lower tray; the vehicle body bottom plate is connected to the connecting pillar through the first locking member , the upper cover and the connecting pillar are connected through the second locking member; the first sealing ring is connected between the underbody and the upper cover, and the second sealing ring is connected between the Between the upper cover and the connecting pillar. The invention can realize the stable connection between the battery pack and the whole vehicle and provide good sealing on the side of the vehicle body and the side of the battery pack.

Description

Technical field [0001] The present application relates to the field of automotive technology, and in particular, there is a battery system connection sealing mechanism, a body and a car. Background technique [0002] At present, in the context of growth in China's car market, the high-speed growth of new energy vehicles sales is a bright color of the car. From the previous two months of sales data from this year, new energy vehicles are becoming the main driving force for the development of domestic cars. However, with the increase in market users, there is a problem that there is a problem. [0003] New energy vehicles are still in the primary stage of development compared to traditional fuel vehicles who have developed more than 100 years. There is a short term of short, long charging time, and insufficient power battery safety. It has restricted consumers to purchase and use the new energy car. To this end, the major car companies have great efforts in the new energy battery l...
