Abstract
The utility model provides a plastic shell of a self-locking structural battery module, aiming to achieve a purpose. The plastic shell of a self-locking structural battery module comprises a base plate and an upper cover, wherein the edge of the base plate is convexly provided with a clamping groove, and a groove body is positioned near one side of the base plate; and the edge of the upper cover is designed into the shape with a hook-shaped section corresponding to that of the clamping groove arranged on the base plate. When the battery module is assembled, glue can be coated in the clamping groove, the base plate is buckled with the upper cover; the edge of the upper cover, which has the hook-shaped section, internally deforms, and the base plate and the upper cover are rebounded after being thoroughly buckled so as to form self-locking.
Description
[technical field]
The utility model relates to a kind of battery modules plastic casing structure, particularly a kind of self-locking structure battery modules plastic casing.
[background technology]
Battery modules is the important component of some electronic products, considers requirements such as the waterproof of battery modules, anti-leakage, and a lot of battery modules all are provided with plastic casing outward.
Fig. 1 is existing battery modules plastic casing structural representation, and the battery modules plastic casing comprises base plate 1, loam cake 2, is respectively equipped with glue groove 10, glue wall 20 on base plate 1, the loam cake 2.Glue on the point in glue groove 10, and the loam cake 2 that closes, base plate 1 get final product.Past, general the use executed the quick hard G485 glue of beating, at present in order to meet UL746C authentication (to being used in the requirement of polymer in the electrical equipment), therefore generally all adopt and execute the quick quick hard G485 glue of beating of executing that hard SX720 glue replaces past usefulness of beating, quick to beat hard SX720 glue silica gel degree of sticking together not high yet execute, and the battery modules plastic casing is difficult to by drop test and shock-testing.Some mode by design grab in the glue groove solves, but because the width of glue groove is very little, and the space is limited, the shell mould of plastics usually can't satisfy the requirement of design grab.Therefore be necessary to provide a kind of self-locking structure battery modules plastic casing in fact.
[summary of the invention]
Main purpose of the present utility model is to provide a kind of and can helps by the relative simple self-locking structure battery modules plastic casing with shock-testing and making of drop test.
To achieve the above object, a kind of self-locking structure battery modules plastic casing of providing of the utility model.This self-locking structure battery modules plastic casing comprises:
Base plate, its edge convexes with draw-in groove, and cell body is positioned near base plate one side;
It is draw-in groove shape on clasp type shape and the corresponding base plate that loam cake, its edge designs become the cross section.
During the assembled battery module, can be in draw-in groove a little executes the quick hard SX720 glue of beating on the point, with base plate, loam cake engaging, the loam cake cross section be the edge of grab shape to internal strain, resilience when engaging puts in place after, formation self-locking.
Compared to prior art, the utility model helps by drop test relative simple with shock-testing and making.
[description of drawings]
Fig. 1 is existing battery modules plastic casing structural representation.
Fig. 2 is the utility model self-locking structure battery modules plastic casing overall schematic.
[embodiment]
Figure 2 shows that a kind of self-locking structure battery modules of the utility model plastic casing structural representation, this self-locking structure battery modules plastic casing comprises:
It is draw-in groove 30 shapes on clasp type shape and the corresponding base plate 3 that loam cake 4, its edge designs become the cross section.
During the assembled battery module, can be in draw-in groove 30 a little executes the quick hard SX720 glue of beating on the point, with base plate 3, loam cake 4 engagings, loam cake 4 cross sections be the edge of grab shape to internal strain, resilience when engaging puts in place after, formation self-locking.
Can there be some openings 41 at loam cake 4 edges according to elasticity, the length design of self material in addition, are that the edge card of clasp type shape is held in the difficulty in the draw-in groove 30 to reduce loam cake 4 cross sections.
Compared to prior art, the utility model helps by drop test relative simple with shock-testing and making.
Claims (2)
1. a self-locking structure battery modules plastic casing is characterized in that, this self-locking structure battery modules plastic casing comprises:
Base plate, its edge convexes with draw-in groove, and cell body is positioned near base plate one side;
Loam cake, its cross section, edge are draw-in groove shape on clasp type shape and the corresponding base plate;
During the assembled battery module, can be in draw-in groove a little glue on the point, the loam cake that closes utilizes self elasticity of plastics of cover rim, is that the edge card of clasp type shape is held in the draw-in groove with the loam cake cross section, reaches the self-locking purpose.
2. self-locking structure battery modules plastic casing according to claim 1 is characterized in that: described cover rim design has some openings.
