Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1 and 2 in combination, the plastic end plate of the battery module comprises an end plate main body 1 and a binding belt 2, wherein the back surface of the end plate main body 1 close to the battery module is a plane, and the front surface is a honeycomb structure; round holes 5 which are communicated from top to bottom are formed in the left side and the right side of the end plate main body 1; at least one group of ribbon limiting protrusions 3 are arranged on the left side and the right side of the end plate main body, the ribbon limiting protrusions 3 limit the ribbon to move in a first direction, and the ribbon placing part 4 is arranged at a position close to the ribbon limiting protrusions 3; the portion of the tie 2 adjacent to the end plate body has a protrusion which is embedded in the honeycomb structure of the end plate body and which limits movement of the tie in a second direction, the first and second directions being opposite. The plastic end plate adopts flame-retardant plastic; the honeycomb structure reduces the weight of the endplate body while also increasing the strength of the endplate body. The ribbon limiting protrusion can be adapted to ribbons of different heights and/or thicknesses; and, through the spacing protruding of ribbon and the bellying on the ribbon and the cooperation of end plate main part, restrict the ribbon and take place the displacement to fixed end plate and battery module better. Just because the honeycomb of ribbon bellying embedding end plate main part plays spacing effect, the spacing arch of ribbon can set up alone, and need not respectively set up a stop device in ribbon both sides, and such structure is more easily production and processing, and it is more convenient when the ribbon is established to the cover, is difficult to cause ribbon stop device's damage.
According to one embodiment of the utility model, a shaft sleeve with a size fit is arranged in the round hole 5. When screwed down, if the sleeve is not added, the surface of the end plate may be cracked. The shaft sleeve is arranged in the round hole, so that the structure of the end plate is stronger.
According to one embodiment of the utility model, the strap placement portion 4 is arcuate. The design of arcwall face makes the ribbon can laminate more with the end plate main part in the corner to fixed end plate and battery module better.
According to one embodiment of the utility model, the front side of the end plate body is provided with a groove 6, and a metal piece with product information is arranged in the groove 6, and the surface of the metal piece is flush with the front side of the end plate body. The metal piece is fixed in the groove 6 through a screw and a buckle. Because the end plate main body is an injection molding piece, the laser is fuzzy in two-dimensional code printing on the plastic piece, so that the code cannot be scanned successfully; if the power of the laser is increased, the surface of the plastic part is easily broken down. According to the utility model, the metal piece with product information is arranged on the end plate main body, so that the two-dimension code can be automatically identified, and the full-automatic line production is realized.
According to one embodiment of the utility model, at least one of the protrusions is formed by snap welding of the two ends of the strap. The plurality of protruding portions can prevent displacement of the ribbon better.
According to one embodiment of the utility model, the left side and the right side of the end plate main body are respectively provided with a weight-reducing groove 7, and a plurality of reinforcing ribs are arranged in the weight-reducing grooves 7. The top surface of the end plate main body 1 upwards forms an extension plate 8, and a plurality of reinforcing ribs are arranged between the extension plate 8 and the top surface. The weight reduction groove and the extension plate can reduce the weight of the end plate main body, and the reinforcing rib can strengthen the bearing force of the end plate main body. When the workshop is assembled, the screws are fixed from top to bottom, and if a tool is improperly used or other reasons, the tool can touch the film of the battery cell, so that potential safety hazards are caused. The reinforcing rib at the top of the end plate can prevent tools from damaging the end plate main body or the cell blue film when the screws are fastened.
According to one embodiment of the utility model, the band limiting protrusions 3 are provided with two groups, the first group of band limiting protrusions 3 are positioned at the upper part of the end plate main body, and the band placing part 4 is arranged above the first group of band limiting protrusions; the second set of band limiting protrusions 3 is located at the lower portion of the end plate body, and the band placing portions 4 are arranged below the second set of band limiting protrusions. The two groups of band limiting protrusions are arranged to fix the plastic end plate and the battery body more firmly, so that the stress on the surface of the end plate is more uniform.
As shown in fig. 2, the battery module 10 includes a battery body and the battery module plastic end plates according to the present disclosure, the battery module plastic end plates are disposed at two ends of the battery body, and the battery body is fixed by the cooperation of the tie-up strap and the two battery module plastic end plates. The battery module has the characteristics of light weight, easiness in production and processing and good stability.
In summary, according to the technical scheme provided by the utility model, the band is limited to displace through the coordination of the band limiting protrusion and the protruding part on the band with the end plate main body, so that the end plate and the battery module are better fixed; the ribbon limiting protrusions can be arranged independently, so that the ribbon limiting device is easier to produce and process, is more convenient to sleeve when the ribbon is sleeved, and is not easy to damage the ribbon limiting device; the two-dimension code can be automatically identified, and the full-automatic line production is realized; the reinforcing rib at the top of the end plate can prevent tools from damaging the end plate main body or the cell blue film when the screws are fastened; has the characteristics of light weight, easy production and processing and good stability.
It is emphasized that: the above embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited in any way, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical substance of the present utility model still fall within the scope of the technical solution of the present utility model.
