The invention discloses a cylindrical battery module, and the module comprises a plurality of cylindrical batteries arranged side by side, battery supports are arranged at the two ends of each cylindrical battery respectively, the ends of the cylindrical batteries are inserted into the battery supports respectively, a cover plate is arranged above the cylindrical batteries, and a bottom plate is arranged below the cylindrical batteries; the cylindrical battery module further comprises a connecting rod, and the connecting rod penetrates through the cover plate, the battery supports and the bottom plate, and is fixed through a fastener. According to the cylindrical battery module disclosed by the invention, the plurality of cylindrical batteries are clamped by the battery bracket to be fixedin the horizontal direction, the connecting rod penetrates through the cover plate, the battery bracket and the bottom plate to finally fix the battery module, the elastic opening and closing openingis formed in the battery bracket, and the connecting rod is propped against the convex part of the elastic opening and closing opening, so the outer walls of the cylindrical batteries are tightly extruded with the supporting grooves; the firm strength is improved, the anti-vibration strength is high, the use risk is reduced, and the service life of the battery box is prolonged.
Description
technical field [0001] The invention relates to a battery, in particular to a cylindrical battery module. Background technique [0002] In the process of assembling traditional cylindrical batteries into modules, due to the curved surface structure of the outer diameter and the tolerance of the outer diameter, it is difficult for the bracket to fix the battery to achieve the effect of fastening each battery cell, and the looseness of the battery cell and the long-term vibration In some cases, it may cause damage to the solder joints between the bus bar and the battery cell, resulting in abnormal voltage and bringing safety risks to the use of the battery box. Contents of the invention [0003] The purpose of the present invention is to provide a cylindrical battery module to solve the technical problem that the solder joints of the busbar and the battery cells are easily damaged during the use of the existing cylindrical battery cells. [0004] In order to achieve the abo...
