As shown in fig. 1 to 12, a method for assembling a battery module according to the present invention is used for assembling the battery module, and specifically includes the following steps:
1) Will spacing slide 41 extending direction becomes the contained angle with the horizontal plane, even fixed frame 4 is placed for the horizontal plane slope, specifically is the length direction of fixed frame 4 becomes the contained angle for the horizontal plane.
Specifically, the range of the formed included angle can be within 5 degrees to 45 degrees, when the included angle is selected to be 5 degrees, after the battery body 1 is inserted into the fixing frame 4, a small gravity component can exist in the length direction of the fixing frame 4, the thrust required by the battery body 1 to slide and walk in the fixing frame 4 can be reduced, the battery body 1 can be conveniently arranged and installed, when the included angle is less than 5 degrees, the gravity component in the length direction of the fixing frame 4 is not obvious, and obvious help can not be formed in arrangement, when the included angle is selected to be 45 degrees, the battery body 1 can directly slide under the action of the gravity component, the battery body 1 does not need to be pushed, the battery body 1 can be automatically arranged in a close fit manner, when the included angle is more than 45 degrees, the gravity component is large, the battery body 1 can impact the static battery body 1 in the sliding process, and the quality is influenced by damage and deformation of the battery body 1.
2) As shown in fig. 12, will battery body 1 puts into in the fixed frame 4, make two on the battery body 1 utmost point post 2 gets into two respectively spacing slide 41, battery body 1 is under the effect of gravity component and the external thrust of exerting in the fixed frame 4 of slope, and the one end of keeping away from ground at fixed frame 4 slides to the one end that is close to ground, until hugging closely adjacent battery body 1 and can't remove again, repeats this step, until whole battery body 1 all install to in the fixed frame 4, at this moment, the anodal and the negative pole post of two adjacent battery body 1 one sides will form the tandem state through the elastic conducting strip 3 electric connection by extrusion deformation.
It should be noted that, in the process of inserting the battery body 1 into the fixing frame 4, the next battery body 1 should rotate one hundred eighty degrees about the central axis in the width direction relative to the previous inserted battery body 1, so that the positions of the two positive and negative poles 2 are exchanged, and therefore, in the fixing frame 4, the single-side poles 2 are arranged in a positive and negative staggered manner, and meanwhile, the elastic conductive sheet 3 connected to the positive pole or the negative pole is in contact with the adjacent positive pole or negative pole, so that the two adjacent battery bodies 1 are connected in series, and the specific arrangement manner is shown in fig. 11.
3) The orientation 1 arrangement direction of battery body, the length direction of fixed frame 4 promptly presses the battery body 1 that is closest to the battery body 1 at fixed frame 4 length direction both ends or the battery body 1 of one of them end, makes each battery body 1 closely laminates, and will through the rubber coating battery body 1 is fixed in fixed frame 4.
When pressing the end battery bodies 1 to make the battery bodies 1 fit, preferably, pressing the battery body 1 with the highest horizontal position in the inclined fixing frame 4 to make the battery body 1 have the tendency of moving towards the battery body 1 with the lowest horizontal position, and by the force component of gravity, the pressure required by pressing can be lowest to make the battery bodies 1 fit and contact stably, and it needs to be noted that the pressing pressure is not too large, so that the excessive deformation generated between the battery bodies 1 is avoided, and the influence of the recovery deformation on the fixing effect when fixing by subsequent gluing is avoided.
When the battery bodies 1 are fixed by gluing, firstly, the gaps between the battery bodies 1 are glued to fix the battery bodies 1, after the battery groups are fixed between the battery bodies 1 to form the battery groups, the battery groups and the fixing frame 4 are glued to fix, and it is noted that when the elastic heat conduction layer 6 is installed, the glue layer can be pre-coated on the elastic heat conduction layer 6 to bond and fix the elastic heat conduction layer 6 and the battery groups.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
