CAR AND RAIL VEHICLE

WIPO Patent Application WO/2022/104951

A1

A car and a vehicle body. The car comprises a car body (10). The car body (10) comprises a first side wall (110) and a second side wall (120) adjacent to each other. An electrical cabinet is disposed in the car body (10) and located at a joint between the first side wall (110) and the second side wall (120). A fireproof cabinet (200) is connected to the car body (10) and provided over the outer side of the electrical cabinet. The fireproof cabinet (200) is made of fireproof composite boards which comprise fireproof boards (310), first aluminum plates (320), light-core rigid boards (330) and second aluminum boards (340), wherein the fireproof boards (310) face away from the electrical cabinet. Since the fireproof cabinet (20) is arranged on the outer side of the electrical cabinet, the electrical cabinet itself does not have to be fireproof. The periphery of the fireproof cabinet (20) is connected to the car body (10) such that the fireproof cabinet and the car body (10) form a closed space to guarantee the fireproof capability. The fireproof cabinet (20) is made of fireproof composite boards, which are lighter, do not generate harmful gas and are more environmentally friendly compared to simple fireproof boards.
