To achieve the above object of the invention, the technical solution used in the present invention is: a kind of battery fastening structure for lithium battery module, including box body and upper cover, multiple insulating spacer is distributed in described box body, constitute battery core between adjacent insulating spacer and between the insulating spacer at two ends and the end plate of box body and accommodate position, it is covered on each battery core receiving position and is provided with protection board, protection board is provided with protection circuit, described protection board arranged on both sides has multiple electrical connection connected with protection circuit, under battery core installment state, the two ends of each electrical connection electrically connect with the extraction electrode of adjacent battery core respectively, described upper cover is coated with described protection board and fixing with described box body is connected.
In technique scheme; during installation; first each battery core is inserted respectively each battery core and accommodates position; extraction electrode is towards open side; being covered by protection board accommodates above position in each battery core again; each electrical connection on protection board is respectively aligned to and compresses the extraction electrode of each battery core, then covers upper cover fixed cover and box body.Usually, battery core accommodates cavity thickness and the battery core thickness matching of position, it is also possible to arranging clamping structure on insulating spacer with fixing battery core, thus, each insulating spacer has simultaneously worked as insulation and the dual function of location.Protection board is arranged at the top of battery core, and power outlet can be arranged on protection board, and electrical connection simultaneously works as voltage signal lead-out wire and the effect of battery electrode connecting line, decreases length of arrangement wire and complexity.
Preferably technical scheme; described electrical connection by stretch out in described protection board side connect post, be perpendicular to connect post arrange and with is connected post weld connection sheet constitute; the two ends of described connection sheet are elastic tip, compress with the extraction electrode of adjacent battery core respectively and connect under battery core installment state.
Further technical scheme, described box body is connected and composed by left and right two half-shell, and each described insulating spacer is made up of the half-breadth partition being connected in left and right two half-shell connecing.Use two half-shell structures, battery core installation process can be facilitated, during installation, first battery core is inserted in one of between each half-breadth partition of half-shell, due to two sides opening, inserts more convenient, another half-shell entirety being inserted between each battery core after completing, making two half-shell merge becomes a housing again.
In technique scheme, described left and right two half-shell are integrally formed structure by ultra-sonic welded.
Or, described left and right two half-shell are adopted and are screwed connection.
Further technical scheme, described on cover and be provided with radiator structure corresponding to the protection circuit on protection board.Such as, when protection circuit arranges multiple metal-oxide-semiconductor structure, multiple metal-oxide-semiconductors can be arranged close to; radiator structure is set in upper this region of correspondence that covers, such as, covers perforate upper; arranging recessed metal fin in hole, during installation, metal fin contacts heat radiation with metal-oxide-semiconductor.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
1, the present invention uses box body to constitute the mounting structure of lithium battery module, arranges fixing insulating spacer in order to separate adjacent battery core in box body, has simultaneously worked as insulation and the effect of location；Therefore, the battery core of the present invention need not be sequentially inserted into epoxy plate blend compounds band when mounted and ties up, and operation is simple and reliable in quality.
2, the present invention will be provided above protection board at box body, and protection circuit is located on protection board, and lead-in wire is apart from short；Meanwhile, electrical connection is set in protection board both sides, for connecting the extraction electrode of adjacent battery core, had both realized voltage signal and introduced, realize again battery series connection (or in parallel), it is not necessary to weldingvoltage holding wire and electrode draw welding successively, simplify installation procedure.
