In the battery technology, the end plates are arranged at the side ends of the battery module and are bound by a binding belt, so that the battery module is stabilized. The free glue of fixed battery that bonds upwards spills over easily when end plate and battery module installation, overflows easily and glues the big face intermediate position of battery monomer, and the colloid forms the colloid hard piece easily, and the battery monomer on the battery module takes place the inflation and contacts with the colloid hard piece and cause electric core local atress, influences electric core life.

SUMMERY OF THE UTILITY MODEL

In view of above-mentioned problem, this application provides an end plate structure, battery module and power consumption device, can solve the battery monomer on the battery module and take place the expansion and glue the colloid hardblock contact of excessive formation on water and cause the local atress of battery monomer, influence electric core life's problem.

First aspect, the application provides an end plate structure, including end plate main part, set up backup pad in end plate main part, be used for the butt joint mouth of jack catch centre gripping, set up a plurality of brace table in end plate main part, be used for cooperating the end strip of end plate main part location, its characterized in that, the lateral wall that the end plate main part is close to the bottom is provided with the fin, and the fin both ends are provided with backflow structure.

In the technical scheme of this application embodiment, set up the fin at end plate main part bottom lateral wall. The design only needs to add a lower arc-shaped structure on the injection molding part, and glue can not overflow to the middle position of the large surface of the battery monomer. The problem that glue is blocked by foam cotton at the original bottom is solved, the foam cotton is seriously deformed when being extruded by glue water, the foam cotton loses efficacy and cannot block the glue water from overflowing, and the glue water is easy to overflow to the middle position of the large surface of the battery monomer to form a glue hard block at the moment. In the use process of charging and discharging of the battery, the single battery body can expand to be locally stressed, and the cycle life of the battery core is influenced.

In some embodiments, the reflow structure includes an upper arc structure and a lower arc structure, and the upper arc structure and the lower arc structure form an inverted chevron shape. Set up backflow structure through fin both ends, backflow structure divide into arc structure, lower arc structure. The lower arc-shaped structure is a downward arc-shaped structure, so that the overflowing glue can flow back, even if part of the overflowing glue is not successfully blocked by the downward arc-shaped structure; go up the arc structure promptly for ascending arc structure, equally can be with glue water conservancy diversion to end plate side position, avoid glue to overflow glue and form the colloid hard block to the big face intermediate position of battery monomer, and then avoid taking place the expansion and overflow the colloid hard block contact that glues the formation and cause electric core local atress because of the battery monomer, influence electric core life's problem, the reflux structure that the fin both ends set up is unified with the bottom of glue backward flow to the module.

In some embodiments, both ends of the end plate body are provided with a snap. In the end plate structure of this application embodiment, the preferred arc of shape of buckle, but the restriction is the arc, and buckle shape, size are with being accurate with battery module cooperation structure. The buckle resilience force is strong, can effectively counterpoint in the module installation, and Y can effectively satisfy end plate structure when installation to the location to the buckle, can not cause the influence to pressurization to back station module Z simultaneously, effectively guarantees to converge the piece welding and does not squint, does not have the influence to the moulding area of bottom half.

In some embodiments, a through opening is provided between each two adjacent support tables. This design is fixed behind the interface at the jack catch card, and the jack catch can stretch into the opening, with the supporting bench extrusion of opening both sides, X can freely stretch out and draw back to big face centre gripping frock, can not interfere with the end plate strengthening rib. Preferably set up three opening, single opening both sides all have a supporting bench, and the jack catch extrudees the laminating with the supporting bench of opening both sides after inserting the opening.

In some embodiments, the bottom end of the end plate body is provided with a support protrusion. The bottom end of the end plate structure can be protruded through the support by the design, and the accuracy of the installation positions of the end plate and the box body is ensured. The bottom surface interference caused by welding or other processes at the bottom of the box body is avoided, the welding quality is influenced, meanwhile, redundant welding spots are easily formed on the lower box body, and the end plate is prevented from being lifted up due to the interference of the welding spots.

In some embodiments, the fins are integrally formed with the end plate body. The fins and the end plate body are formed in one-time injection molding mode, and extra foam is not needed. The module pushes down the in-process and can block the colloid through arc structure down, and fin both sides are equipped with the water conservancy diversion structure simultaneously, reflux structure promptly. The two close edges of the unilateral flow guide structure are made into the flow guide structure again, namely, the lower arc structure is additionally provided with the upper arc structure. The single-side flow guide structure is provided with a downward arc structure and an upward arc structure, and the glue only overflows to two sides of the battery core. In the cell cycle expansion process, an extrusion space is left on the large surface.

In some embodiments, the through openings in the end plate structure are open. This design can not inject the thickness of fork arm when outside frock downwardly extending to the opening, effectively avoids closing the opening in the past, restriction frock thickness, and frock pressurized lamella thickness is too thin, leads to the frock to warp, and the module drops when the transportation. Adopt the opening design of open type, the big face pressurization frock part can thicken to being more than or equal to 15mm this moment, can effectively guarantee the stability of transportation process, can optimize thickness about the structure of frock promptly, can strengthen the intensity of frock structure.

In some embodiments, at least two support protrusions are provided on the end plate structure. Preferably set up two support protruding, two support protruding can be satisfied with the high-efficient material when sparingly moulding plastics of counterpointing of lower box. The position of the supporting protrusion is flexibly arranged according to the corresponding of the lower box body structure, and the end plate can be suitable for more product structures.
