Description

Battery box, battery and electric equipment Technical Field The application relates to the field of energy storage, in particular to a battery box, a battery and electric equipment. Background With the rapid development of the new energy automobile industry, the performance requirements of the battery box body are increasingly strict, and the requirements of light weight, high insulativity, excellent heat preservation performance, bottom impact resistance protection and the like are required to be met. In the related art, the battery case is generally manufactured by stamping or welding a metal material. In order to exchange heat with heat generated by the battery during operation, a heat exchange member is generally required to be arranged in the battery box, so that the energy density of the battery is reduced and the preparation cost of the battery is increased. Disclosure of utility model The embodiment of the application provides a battery box, a battery and electric equipment, which can improve the energy density of the battery and reduce the preparation cost of the battery. In a first aspect, an embodiment of the present application provides a battery box, including: A frame; The tray assembly is arranged on one side of the frame and connected with the frame, wherein the tray assembly comprises a heat exchange piece and a tray, the tray and the heat exchange piece are pressed together through a stamping process to form an integral piece, and the tray is made of an insulating material. In one possible embodiment, the tray has a burring part covering a part of the top surface of the heat exchange member in the circumferential direction of the heat exchange member. In one possible embodiment, the tray is any one of a polypropylene honeycomb panel, a polyvinyl chloride honeycomb panel, a polyurethane foam panel, a polypropylene foam panel, and a polystyrene foam panel; And/or the frame is made of any one of glass fiber composite material, carbon fiber composite material and metal material. In a possible embodiment, the side of the tray facing away from the frame is provided with a receiving groove which penetrates the tray in a direction facing away from the frame and in a direction facing away from the center of the tray; the frame surrounds the tray assembly and is arranged in the accommodating groove. In one possible embodiment, the frame includes a frame body and an extension connected with an end of the frame body toward the tray assembly and extending toward a center of the tray assembly; The frame body wraps the circumference of the tray assembly, the extension portion is arranged in the accommodating groove, and the extension portion and the surface of the tray, which is away from the frame body, are flush with each other. In one possible embodiment, the receiving groove is an annular groove. In one possible embodiment, the battery case further includes a protection plate disposed at a side of the tray assembly facing away from the frame and connected with the frame and the tray assembly, respectively. In one possible embodiment, the shielding plate is connected to the frame and the tray assembly, respectively, by an adhesive layer.
