Retaining device for at least one battery cell
The invention relates to a retaining device for at least one battery cell, wherein the retaining device comprises at least two retaining elements, wherein each retaining element comprises at least one fastening means, wherein the at least two retaining elements are mechanically detachably connected by means of the fastening means.
1. A retaining device for at least one battery cell ( 25 ), wherein the retaining device comprises at least two retaining elements ( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 )), wherein each retaining element ( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 )) comprises at least one fastening means ( 20 ( 1 a ), 20 ( 2 a ), 20 ( 3 a ), 20 ( 4 a ), ( 20 ( 1 b ), 20 ( 2 b ), 20 ( 3 b ), 20 ( 4 b )), characterized in that the at least two retaining elements (( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 ))) are connected in a mechanically releasable manner by the fastening means ( 20 ( 1 a ), 20 ( 2 a ), 20 ( 3 a ), 20 ( 4 a ), 20 ( 1 b ), 20 ( 2 b ), 20 ( 3 b ), 20 ( 4 b )), wherein first fastening means ( 20 ( 1 a ), 20 ( 1 b ), 20 ( 2 a ), 20 ( 2 b )) have an s-shaped guide rail which corresponds to an inverted form of an s-shaped groove of second fastening means ( 20 ( 3 a ), 20 ( 3 b ), 20 ( 4 a ), 20 ( 4 b )), wherein the retaining elements ( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 )) provide a form-fitting connection with the battery cell ( 25 ), wherein the retaining device surrounds end faces and side faces of the at least one battery cell ( 25 ), and wherein at least one of the retaining elements ( 20 ( 1 ), 20 ( 2 )) having the first or second fastening means ( 20 ( 1 a ), 20 ( 2 a ), 20 ( 3 a ), 20 ( 4 a ), ( 20 ( 1 b ), 20 ( 2 b ), 20 ( 3 b ), 20 ( 4 b )) further comprises a further fastening means ( 20 ( 1 c ), 20 ( 2 c )) having a form complementary to an upper face of the at least one battery cell ( 25 ) and engaged therewith to retain the at least one battery cell ( 25 ).
2. The retaining device according to claim 1 , characterized in that a first retaining element ( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 )) and a second retaining element ( 20 ( 1 ), 20 ( 2 ), 20 ( 3 ), 20 ( 4 )) are connected one to the other at a right angle.
3. A battery module ( 26 ) comprising at least one battery cell ( 25 ) having a retaining device according to claim 1 .
4. A motor vehicle having at least one battery module ( 26 ) according to claim 3 .
