Vehicle-mounted battery installation platform

The invention relates to a vehicle-mounted battery installation platform which comprises a base, at least three fixed-length connection rod mechanisms, a drive mechanism and a work table. Each fixed-length connection rod mechanism comprises a fixed end arranged on the base and a free end opposite to the fixed end. The free ends are telescopic relative to the fixed ends. The drive mechanism is in linkage with the fixed-length connection rod mechanisms. The drive mechanism can drive the free ends to stretch out and retract back. The free ends of the three fixed-length connection rod mechanisms are arranged on the work table at intervals. The free ends and the work table are rotatably connected. The vehicle-mounted battery installation platform can achieve space posture adjustment, so that the installation platform is matched with a battery box in space posture, the installation platform is in accurate butt joint with the battery box when batteries are taken out or stored, and impact to the battery box and a vehicle is avoided.
