Problems solved by technology
[0002] At present, in order to ensure the sealing reliability of the battery tank cover, valve-regulated sealed lead-acid batteries gradually implement heat-sealing technology, and in order to ensure that the battery has a higher cycle life, a larger assembly ratio is adopted. In this way, a The problem is that with the increase of the battery assembly ratio, the wall of the battery tank perpendicular to the polar plate will sag inward. The larger the specification, the more serious the sag, but the four sides of the battery cover do not change, which leads to the heat of the battery cover. The sealing interface becomes smaller, seriously affecting the reliability of battery sealing performance

Embodiment Construction
[0014] As shown in Figures 1, 2, and 3: the method to prevent the deformation of the battery tank is to install a frame-shaped battery tank with a size corresponding to the inner wall of the battery tank on the top of the battery plate during the battery tank assembly process. stand. The shape of the bracket is a grid-like rectangular parallelepiped structure, including two major parts, the transverse support arm (1) and the longitudinal support arm (2), and the outer edge of the bottom of the frame is chamfered; the transverse support arm (1), the longitudinal support arm ( 2) Both are designed so that the height dimension is greater than the width direction dimension; both ends of the lateral support arm (1) are large rounded corners (3), and there are convex corners (4) above the large rounded corners.

The present invention relates to a method for preventing the deformation of a battery jar; a frame battery jar bracket with the dimension corresponding to the inner wall of the battery jar is arranged in the battery jar in the upper direction of a battery polar plate in the process of assembling the battery jar. The shape of the battery jar bracket is a gridding-shaped cuboid structure which comprises a transverse supporting arm and a longitudinal supporting arm; the outer edge of the bottom of the frames of the structure is provided with chamfer angles. The height of the transverse supporting arm and the longitudinal supporting arm are designed to be greater than the width of the transverse supporting arm and the longitudinal supporting arm. Two ends of the transverse supporting arm are provided with big round angles; the upper part of the round angles is provided with salients. The invention has the advantages that when the invention is used, the invention is positioned on the upper part of the battery jar; the wall of the battery jar is supported through the longitudinal supporting arm and the transverse supporting arm in order to prevent from sinking inwards as the battery assembly ratio increases, thereby ensuring heat sealing jointing surface of the battery jar cover and the reliability of battery sealing.
Description
technical field [0001] The invention relates to a lead-acid storage battery, more specifically a method for preventing deformation of a battery tank and a battery tank support involved in using the method. Background technique [0002] At present, in order to ensure the sealing reliability of the battery tank cover, valve-regulated sealed lead-acid batteries gradually implement heat-sealing technology, and in order to ensure that the battery has a higher cycle life, a larger assembly ratio is adopted. In this way, a The problem is that with the increase of the battery assembly ratio, the wall of the battery tank perpendicular to the polar plate will sag inward. The larger the specification, the more serious the sag, but the four sides of the battery cover do not change, which leads to the heat of the battery cover. The sealing interface becomes smaller, which seriously affects the reliability of the battery sealing performance. Contents of the invention [0003] The purpo...
