Abstract
The utility model relates to a flat type cell shell body, particularly the improvement of the structure of the flat type cell shell body. An upper cover is rectangular. Four edges of the upper cover are inwards concave, and are in the shape of a ship. When the flat type cell shell body is installed, the circumference of the rectangular upper cover contacts the inner wall of a rectangular outer shell body. The top surface of the upper cover and the top surface of the outer shell body are on the same plane, and are in welded connection. Welding seams are positioned on four edges of the top surface of the upper cover, in this way, the distance of the welding seams and components of the upper cover is enlarged, and the influence of heat generated in welding on the components of the upper cover is reduced. The components on the upper cover are positioned on a concave bottom, and the influence of thermal radiation generated in welding on the components is correspondingly lowered.
Description
The utility model is a kind of platypelloid type battery container, particularly to the improvement of platypelloid type battery container superstructure.
Battery generally all can be emitted gas in charging and discharging process.The enclosure interior that accumulates in the gas of emitting has caused very big pressure, and pressure can reach 10kg/cm.Housing must be able to afford so big pressure.For the platypelloid type battery, the distortion meeting of housing is more remarkable, can cause very big stress on the seam between loam cake and the housing.So will adopt Welding Structure between the loam cake of platypelloid type battery and the housing.Because the platypelloid type battery has a lot of parts to concentrate near the loam cake weld seam, therefore good except the intensity that requires to weld, beyond weld seam can not leak, more require when welding energy to concentrate, can not produce thermal impact near the parts it.Generally laser welding to be adopted, other welding equipment can not be used.Because superstructure is a plane, heat that is produced during welding and thermal radiation still can produce thermal impact near the parts it, and laser welding cost height not only, and the requirement in butt welded seam district is also high, and is careless slightly, will cause weld leakage.
The purpose of this utility model is the shortcoming that overcomes above-mentioned platypelloid type battery container structure, a kind of platypelloid type battery container of new construction is provided, the heat and the thermal radiation that are produced when welding can not produce thermal impact near the parts it, can adopt other welding equipment that is different from laser welding.
The purpose of this utility model is to realize like this.The platypelloid type battery container, loam cake 1 is a rectangle, four limits concave, and become the ship type; During installation, the rectangle loam cake around contact with the inwall of rectangle shell body 2, the end face of loam cake and shell body end face at grade, loam cake and shell body are by being welded to connect, weld seam 3 is positioned at four limits of upper cover top surface.
The utility model is owing to the structure that adopts loam cake to concave, and weld seam is positioned at loam cake four limits, has so just widened the distance between weld seam and the loam cake parts, and the heat that has produced when having significantly reduced welding is to the influence of the parts on it; On the parts that cover be positioned at concave bottom, the also corresponding thermal radiation that produces when having reduced welding is to the influence of parts.Therefore, the battery container of this structure also can adopt other welding equipment that is different from laser welding to weld, when adopting other welding equipment to weld, can adopt bigger energy, strengthen fusion penetration, thereby greatly reduce requirement, also improved the rate of finished products of product greatly housing and loam cake.
The utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is end views of accompanying drawing 1.
1 loam cake, 2 shell bodies, 3 weld seams.
Embodiment:
The platypelloid type battery container, loam cake 1 is a rectangle, four limits concave, and become the ship type; During installation, square loam cake around contact with the inwall of rectangle shell body 2, the end face of loam cake and shell body end face at grade, loam cake and shell body are by being welded to connect, weld seam 3 is positioned at four limits of upper cover top surface.
Claims (1)
1, a kind of platypelloid type battery container includes rectangle shell body 2, it is characterized in that loam cake 1 is rectangle, and four limits concave, and become the ship type; During installation, the rectangle loam cake around contact with the inwall of shell body, the end face of loam cake and shell body end face at grade, loam cake and shell body are by being welded to connect, weld seam 3 is positioned at four limits of upper cover top surface.
