Embodiment

[0025] like figure 1 As shown, a sealing structure between batteries with multiple cells of the present invention includes a battery case 1 in the shape of a cuboid. In the cavity of the battery case 1, several longitudinal separators 2 are arranged equidistantly along the length direction. The battery case 1 The cavity is divided by the medial partition 2 to form several battery slots 3, and the two ends above the medial partition 2 are provided with square bridge gaps 5 that can accommodate the passage of the bridge connector 4, such as figure 2 and Figure 4 As shown, the bridge connector 4 is a U-shaped structure with the opening facing downwards. The U-shaped bridge connector 4 is clamped on both sides of the bottom of the bridge gap 5, and its open ends are respectively along the battery slot 3 on the corresponding side. The water on the top surface of the battery sheet extends outwards, and the bridge connector 4 corresponding to the bridge gap 5 is covered with a wra...

Abstract

The invention discloses a sealing structure, which provides a simple structure, reliable sealing, which can effectively avoid liquid leakage between single cells after heat sealing, and ensure the performance and quality of the battery. The molding method of the sealing structure solves the technical problem that the liquid leakage between single cells often occurs after heat sealing in the prior art, which leads to the inability to guarantee the performance and quality of the battery. It includes a battery case, a battery case A number of battery slots are formed through the separation of the medial partition, and a bridge gap that can accommodate the passage of the bridge connector is provided above the mediastinal board. The bridge connector is a U-shaped structure with the opening facing downward, and the U-shaped bridge connection The parts are clamped on both sides of the bridge gap, and their open ends respectively extend outward into the battery slots on the corresponding sides. The corresponding bridge connectors at the bridge gap are covered with a wrapping layer, and the edges of the wrapping layer are in contact with the corresponding mediastinum. The plates are fused together.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a multi-cell sealing structure of a battery with simple structure and reliable sealing, which can effectively avoid liquid leakage between cells after heat sealing, and a forming method of the sealing structure. Background technique [0002] In the existing plastic shell batteries, the sealing methods between the battery tank and the battery cover mainly include glue sealing and heat sealing. The glue seal is to use the sealant to bond the battery tank and the battery cover together. , strong adaptability, the disadvantage is that the curing time of the sealant is long, the solvent is volatile and toxic, and the sealant increases the cost of the battery; heat sealing is to use a heating mold to melt the edge of the battery tank cover, and then press and bond the tank cover together. The advantage of heat sealing is that it saves the sealant and saves cost. At the same time, the sealing oper...
