Description
Technical Field
The utility model relates to a battery module field, concretely relates to bipolar post module.
Background
Lithium battery system's battery module adopts the monopole ear mode more in the existing market, and the monopole ear mode will cause module end high pressure pencil to walk the line mode single, has seriously restricted the application range of module, and because the restriction in box space and pencil buckle arrange unreasonablely, will lead to the pencil in disorder and with the box friction, cause the epidermis damaged, have the electric leakage risk.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a bipolar post module solves, it is right next the utility model discloses do further to explain.
A bipolar column module comprises an electric core and a plastic integrated board, wherein a pole piece is integrated on the plastic integrated board and connected to the electric core, a bipolar column is formed on the integrated board, a wiring groove is formed in the integrated board, the integrated board is connected with a pressing plate, a wiring harness buckle and a socket piece buckle which are located above the wiring groove are connected to the pressing plate, and wiring harnesses in the wiring groove are bound by the wiring harness buckle and the socket piece buckle; the pressure plate is also provided with an explosion-proof valve avoiding hole which is over against the explosion-proof valve.
Preferably, the explosion-proof valve avoiding hole is arranged in a long strip shape.
Furthermore, an explosion-proof valve avoiding hole is formed above the wiring groove, the edge of the explosion-proof valve avoiding hole is formed in the wire column, and the wire harness is avoided from the explosion-proof valve avoiding hole under the dredging of the wire column.
Has the advantages that: compared with the prior art, the bipolar column module provided by the utility model solves the problem of limitation of the module in the serial-parallel direction, and facilitates the diversified layout of a battery system; in addition, the wiring harness buckle and the connector buckle are arranged on the pressing plate, so that the assembly operability is improved, the integral wiring of the module wiring harness is smoother, the fixing is more firm, and the risk of damage of the wiring harness is reduced; still increase explosion-proof valve and dodge the hole, can let electric core release pressure faster under extreme condition, promote the security of system.
Drawings
FIG. 1: the structure of the utility model is shown schematically;
in the figure: the explosion-proof valve assembling device comprises an integrated board 1, a pressing board 2, a wiring groove 3, a wiring harness buckle 4, a socket buckle 5 and an explosion-proof valve avoiding hole 6.
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1.
A bipolar column module comprises an electric core and a plastic integrated plate 1, wherein a pole piece is integrated on the plastic integrated plate 1 and is welded on the electric core through laser, and a bipolar column is formed on the integrated plate and is convenient for series connection and/or parallel connection between modules; the integrated board 1 is connected with the pressing plate 2 in a buckling mode, the plastic integrated board 1 is provided with the wiring groove 3, the pressing plate 2 is connected with the wiring harness buckle 4 and the socket piece buckle 5 which are located above the wiring groove 3, and the wiring harness buckle 4 and the socket piece buckle 5 enable the wiring harness to be integrally and smoothly routed and are fixed more firmly.
In this embodiment, be provided with explosion-proof valve dodge hole 6 on clamp plate 2, explosion-proof valve dodge hole 6 just to explosion-proof valve, and electric core can rush away electric core explosion-proof valve fast under the extreme condition that takes place thermal runaway, promotes battery system's security performance.
The arrangement of the explosion-proof valve has certain flexibility, the main stream is provided with the explosion-proof valve avoiding hole 6 above the wiring groove 3, namely, the wiring harness is to pass through the explosion-proof valve avoiding hole 6, after the pressing plate 2 is pressed on the integrated plate 1, the wiring harness and the explosion-proof valve avoiding hole 6 are cut and rubbed, damage and danger are caused to the wiring harness, after the explosion-proof valve acts, airflow is flushed out of the explosion-proof valve avoiding hole 6, the wiring harness blocks the explosion-proof valve avoiding hole 6, and high-speed airflow causes huge impact force to the wiring harness, so that the wiring harness is loosened and is not beneficial to explosion prevention, therefore, the edge of the explosion-proof valve avoiding hole 6 is arranged on the wire column, and the wiring harness avoids the explosion-proof valve avoiding hole 6 under the dredging of the wire column.
The explosion-proof valve avoidance hole 6 is arranged to be long-strip-shaped, so that the processing is easy, and a certain weight reduction effect is achieved.
The utility model is easy to assemble, firstly, the battery cell is fixed by a packing belt, and a welding pole piece is prepared; then, integrating the pole piece on the integrated board, and welding the pole piece on the battery cell by laser welding; then, fastening the pressure plate provided with the explosion-proof valve avoidance hole on the integrated plate through a buckle; and finally, mounting a wire harness buckle and a connector buckle on the pressing plate, and dredging and optimizing the layout of the wire harness, namely completing the assembly.
The utility model provides a bipolar column module, has solved the restriction problem of module series-parallel connection direction, makes things convenient for the diversified overall arrangement of battery system; in addition, the pressing plate 2 is provided with the wiring harness buckle and the connector buckle, so that the assembly operability is improved, the integral wiring of the module wiring harness is smoother, the fixing is more firm, and the risk of damage of the wiring harness is reduced; still increase explosion-proof valve and dodge the hole, can let electric core release pressure faster under extreme condition, promote the security of system.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
