The invention relates to a high-safety bed and cabinet integral unit special for a bay window. The high-safety bed and cabinet integral unit comprises a cabinet body, a bed surface and a right triangle support. The bed surface refers to a rectangular flat plate. The cabinet body is in the shape of a cuboid. The length of the bed surface is equal to that of the cabinet body; the ratio of the width of the bed surface to that of the cabinet body is equal to 1.5-2. Two short edges of the bed surface and two short edges of the upper surface of the cabinet body coincide; the outer edge of the bed surface and the long edge, close to a cabinet door, of the upper surface of the cabinet body coincide. According to the integral design of the bed and the cabinet, pressure from the bed surface to the upper surface of the windowsill of the bay window can be reduced greatly and safety of the bay window can be improved; the bed surface can be supported through a slide self-locking unit so that stability of the bed surface is guaranteed; a blind device can prevent the bed surface from being exposing to the sun to be too hot or prevent rainwater intrusion from wetting the bed; when people sleeps on the bed, the door of the cabinet door is locked, and beside the sleeping time, the door of the cabinet door is unlocked at the other time, and thus the burglar prevention is achieved. The high-safety bed and cabinet integral unit adopts solar energy to charge its members, and accordingly is energy-saving and environmental-friendly.
