Abstract

The utility model discloses an integrated apron of battery module, include: the integrated apron, connect pole piece, positive negative pole piece, square pressure rivet nut. The integrated cover plate is characterized in that the positive and negative pole pieces and the square pressure riveting nut are combined into a whole, a square groove is formed in the corresponding position of the integrated cover plate, and the square groove is connected with the square pressure riveting nut in a buckling mode. The utility model discloses a set up the square pressure rivet nut of fixed usefulness on utmost point post, when making the battery in groups, except the welding, still can directly connect apron and machine utmost point post through the buckle, if higher to the vibration requirement moreover, weld utmost point post and integrated apron again after the buckle to improve battery cover plate's commonality and reliability. Square nut is riveted to positive negative pole piece pressure, when the square groove cooperation with integrated apron, connect reliably, the unable fastening problem of screw when can avoiding riveting the nut to drop, apron and pole piece simple structure, it is with low costs, do benefit to batch production and later stage and dismantle the maintenance.

Description

Integrated apron of battery module

Technical Field

The utility model relates to a battery technology field, a battery module integration apron.

Background

Lithium ion batteries are classified into ternary batteries, lithium iron phosphate batteries, lithium cobalt oxide batteries, lithium manganese batteries and the like according to the positive electrode materials. At present because the place that the lithium iron phosphate battery was applied to the energy storage is less, and uses more with the power aspect, consequently, is difficult to drop under the vibration environment for a long time after guaranteeing the battery in groups, selects the utmost point post of welding mode usually to improve the reliability that the battery used, but the welding mode is very inconvenient at utmost point post and apron.

With the progress of the lithium battery industry, energy storage is also developing towards light weight, the situation that the energy storage needs to be screwed can exist, but the existing power battery cover plate only adopts a welding mode, and the universality is poor. Therefore, a universal battery cover plate is needed, and both a welding mode and a buckling connection mode can be selected during grouping.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses an integrated apron of battery module has solved the unable general problem of power battery apron.

An integrated apron of battery module includes: the integrated apron, connect pole piece, positive negative pole piece, square pressure rivet nut. The integrated cover plate is characterized in that the positive and negative pole pieces and the square pressure riveting nut are combined into a whole, a square groove is formed in the corresponding position of the integrated cover plate, and the square groove is connected with the square pressure riveting nut in a buckling mode.

Furthermore, the length of the square rivet pressing nut is smaller than the depth of the square groove.

Further, positive and negative pole pieces and the square rivet pressing nut are welded into a whole, the number of the square rivet pressing nuts is 4, and the positive pole and the negative pole in the positive and negative pole pieces are respectively provided with two square rivet pressing nuts.

Furthermore, the connecting pole piece is positioned in the middle of the integrated cover plate and is connected together by ultrasonic welding.

Furthermore, the square groove is located the lower part of integrated apron, set up 4 altogether, respectively with square pressure rivet nut tight fit matches.

The utility model discloses a set up the square pressure rivet nut of fixed usefulness on utmost point post, when making the battery in groups, except the welding, still can directly connect apron and machine utmost point post through the buckle, if higher to the vibration requirement moreover, weld utmost point post and integrated apron again after the buckle to improve battery cover plate's commonality and reliability. Square nut is riveted to positive negative pole piece pressure, when the square groove cooperation with integrated apron, connect reliably, the unable fastening problem of screw when can avoiding riveting the nut to drop, apron and pole piece simple structure, it is with low costs, do benefit to batch production and later stage and dismantle the maintenance.

Drawings

Fig. 1 is a schematic structural view of an integrated cover plate of a battery module according to an embodiment of the present invention;

legend: 1. integrated apron, 2 connection pole pieces, 3 positive negative pole pieces, 4 square pressure rivet nuts, 5 square grooves.

Detailed Description

The present invention is further illustrated by the following examples, but is not limited to the contents of the specification.

An integrated apron of battery module includes: the integrated apron, connect pole piece, positive negative pole piece, square pressure rivet nut. The positive and negative pole pieces are integrated with the square pressure riveting nut, a square groove is formed in the corresponding position of the integrated cover plate, and the square groove is connected with the square pressure riveting nut in a buckling mode. Therefore, the universality and reliability of the power battery integrated cover plate are improved.

Furthermore, the length of the square pressure riveting nut is smaller than the depth of the square groove, so that the square pressure riveting nut is guaranteed to be completely immersed into the square groove, leakage is avoided, and the safety of the power battery is improved.

Further, positive and negative pole pieces are welded with square pressure riveting nuts into a whole, the number of the square pressure riveting nuts is 4, and two square pressure riveting nuts are respectively arranged on the positive pole and the negative pole of the positive and negative pole pieces. The reliability of the pole is guaranteed, the square pressure riveting nut is still reliable under the condition that the square pressure riveting nut fails, and sufficient time is left for overhauling and repairing.

Furthermore, the connecting pole pieces are positioned in the middle of the integrated cover plate and are connected together by ultrasonic welding. The reliability of the power battery is improved.

Furthermore, the square groove is located the lower part of integrated apron, sets up 4 altogether, respectively with square pressure rivet nut tight fit cooperation. The reliability of the power battery is improved.
