Chassis assembly and vehicle

A chassis assembly for vehicle, comprising:

• a chassis with multiple mounting positions, and is configured to install a battery module;
• a quick-release device through which the battery module is installed on the mounting positions, wherein the quick-release device is controlled by a control system;
• and
• a voltage electrical connecting assembly in quick plug-in electrical connection to the battery module, wherein the voltage electrical connecting assembly is controlled by the control system;
• wherein the voltage electrical connecting assembly includes a high-voltage electrical connecting assembly which is in quick plug-in electrical connection to the battery module and controlled by the control system;
• wherein the high-voltage electrical connecting assembly includes:
• a first quick plug-in connector;
• and
• a high-voltage electrical connecting module arranged to be electrically connected to the battery module through the first quick plug-in connector;
• wherein the first quick plug-in connector includes:
• an inserting post, a first end of which passes through an insertion hole provided on a connecting flange of the battery module, wherein a cavity is defined in the inserting post, a through-hole communicating with the cavity is defined on an outer peripheral wall of the first end of the inserting post;
• an expanded elastomeric assembly disposed in the through-hole, configured to partially protrude from the outer peripheral wall of the inserting post and pressing against a lower surface of the connecting flange;
• and
• a limiting flange surrounding the outer peripheral wall of the inserting post, wherein a lower surface of the limiting flange presses against an upper surface of the connecting flange.
