Manufactured conductor welds together with battery core monomer, forms the battery pack of string and structure.The welding manner in maintenance process by
In welding contact surface is big, welding material is difficult to decompose so that fragile battery core, maintenance difficulties are higher.Two are formed with lithium ion battery
One of the major maintenance difficult point for taking turns electric vehicle battery module is lossless disassembles and follow-up welding again.
Therefore a kind of plastics on new materials and the conductor of structure are designed, and uses and can be substituted now with the welding procedure that quick nondestructive is disassembled
There is material and technology just to become particularly significant.This new design requirement has enough mechanical strengths and electric stress adaptability, both
It is reliable and stable but can rapid disassembling, again weld after performance do not reduce, to meet the application conditions of electric car.
The content of the invention
It is an object of the invention to provide a kind of lithium ion battery module based on BONDING techniques, to facilitate lithium ion
The later maintenance work of battery modules.The present invention provides following technical scheme：
A kind of lithium ion battery module based on BONDING techniques, the battery modules are to be made up of the type battery of multiple lines and multiple rows 18650
Battery modules, the battery per a line or each row is collectively aligned, i.e., the battery of a line or a row, positive pole point to same
Side, negative pole point to the same side.Two electrode sides of battery modules are compressed by two retable glue supports, and peace is fixed in the outside of plastic rubber bracket
Equipped with aluminium nickel compound board, the aluminium nickel compound board is connected to the electrode of the lithium ion battery by BONDING lines.
As a preferred embodiment of the present invention, the end of the plastic rubber bracket is installed with multiple conducting bolts, described to lead
Positive pole or negative pole of the electric bolt as the battery modules.Conducting bolt company of fixation by way of welding or nut are fixed
Aluminium nickel compound board is connected to, is formed and electrically connected with aluminium nickel compound board.
As another preferred scheme of the present invention, the BONGDING lines are aluminium wire.The diameter of aluminium wire can be according to lithium
The performance of ion battery module needs to be selected.
As another preferred scheme of the present invention, the BONDING lines are formed by way of ultrasonic bond.
The present invention has the following advantages：
1st, the present invention uses electrical connection carrier of the BONGDING lines as battery electrode and aluminium nickel compound board, and speed of welding is fast, carries
The operating efficiency of high battery modules welding；
2nd, the present invention use aluminium wire to be electrically connected as BONGDING lines, aluminium wire has action of fuse, further to lithium from
Sub- battery modules form protection；
3rd, lithium ion battery module later maintenance of the present invention is disassembled conveniently, and solder joint damage is small, and not easy damaged battery core, i.e., does not damage
18650 type batteries, serious forgiveness are high；
4th, the present invention program configures battery modules conveniently, by configuring the aluminium wire of varying number and size, can adjust module
Fan-out capability.
Brief description of the drawings

Embodiment
The process example is elaborated below, so that advantages and features of the invention can be easier to by this area skill
Art personnel understand, apparent are clearly defined so as to be made to protection scope of the present invention.
As shown in Fig. 1 battery module structure schematic diagrames of the present invention, the present embodiment is the 4 of 4 × 8 18650 type batteries 1 compositions
The battery pack that row 8 arranges, battery plus-negative plate direction is oppositely positioned between the battery of adjacent column, after battery pack arranges, passes through plastic cement
Support 2 fixes battery pack, and a plastic rubber bracket 2 is respectively placed in battery pack both sides, and one end of plastic rubber bracket 2 is embedded with conducting bolt
21.Aluminium nickel compound board 3 is pressed in the outer surface of plastic rubber bracket 2, and the fixed-link of plastic rubber bracket 2, while the conduction of plastic rubber bracket 2
Bolt 21 is conductively connected with aluminium nickel compound board 3.The electrode of aluminium nickel compound board 3 and 18650 type batteries 1 is carried out by BONDING lines
Connection.This connects through the connection that ultrasonic bond technique realizes high reliability.BONDING lines at this are aluminium wire.Pass through and configure
Different aluminium wire sizes, but realize the fan-out capability for freely adjusting module.
After 18650 type batteries 1, plastic rubber bracket 2, aluminium nickel compound board 3 all fix, while BONDING lines are connected, then should
Battery modules are completed, and draw the positive pole and negative pole of battery modules respectively by conducting bolt 21, you can carry for working cell
For driving power.
One of the foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto,
Any those skilled in the art disclosed herein technical scope in, the change that can expect without creative work
Change or replace, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with claims
