Description

Double-end utmost point ear soft-packaged fixed bolster for electric core

Technical Field

The utility model relates to a soft-packaged electrical core, especially a be applicable to double-end utmost point ear soft-packaged electrical core and use fixed bolster.

Background

In recent years, along with economic development, people have higher and higher consumption requirements on various products, higher requirements on product iteration speed and innovation are provided, and the product competition pressure is strengthened more and more; especially in the new energy field, along with the continuous maturity of soft package lithium ion battery core technique, the soft package battery core of double-end utmost point ear is more and more accepted and accepted by more battery manufacturing enterprises owing to possess wider utmost point ear, great discharge capacity. However, the tab of the double-head tab structure is led out from the upper direction and the lower direction, so that the conventional single-head tab output assembly cannot be used for reference when the tab is combined, and a new assembly mode is required to adapt to the double-head tab soft-package battery core.

Disclosure of Invention

The utility model aims at designing a rational in infrastructure, excellent in use effect's soft packet of electricity core of double-end utmost point ear and using fixed bolster.

The technical scheme of the utility model, a double-end utmost point ear soft-packaged electrical core is with fixed bolster, it includes the fixed bolster plate body, its characterized in that: four corners of the frame-shaped fixed support plate body are respectively provided with a placing groove, the upper end and the lower end of each of two sides of the fixed support plate body are respectively provided with an upper cover square hole groove, the upper plate body and the lower plate body of the frame-shaped fixed support plate body are symmetrically provided with a soft-packaged lug square hole groove, two sides of the soft-packaged lug square hole groove are preset with screw holes, two side plate bodies of the fixed support plate body are symmetrically provided with fastening adhesive tape preformed grooves, and the upper part and the lower part of the fixed support plate body, which are close to the fastening adhesive tape preformed grooves, are respectively provided with a heating sheet square hole groove; the plate bodies on the two sides of the fixed support plate body are provided with spring buckles, and the placing grooves are respectively provided with spring buckle grooves corresponding to the positions of the spring buckles.

Preferably, an M3 embedded nut is installed in the screw hole;

preferably, the number of the screw holes is 4;

preferably, the number of the spring buckles is 4.

Preferably, the material type of the fixed support plate body is flame-retardant ABS.

The utility model discloses a use as follows:

the battery cell is assembled firstly by matching the spring fastener of the former fixed support with the spring fastener groove of the latter fixed support, then the next battery cell is put in, the next fixed support is buckled, and the like in sequence, so that series-parallel combination of a plurality of battery cells can be realized, and the assembly of a power supply system is realized.

The utility model has the advantages that:

the utility model discloses a structure is special to the structure mode of double-end utmost point ear soft-packaged electrical core, designs out a soft-packaged support of longitudinal symmetry, and fundamentally has solved the cluster parallel assembly problem of double-end utmost point ear soft-packaged electrical core.
