Abstract

Provided is a battery module. The battery module according to an embodiment of the present disclosure may include: a cartridge assembly including a plurality of cartridges configured to receive battery cells; a substrate protecting body combined to the cartridge assembly; a casing configured to receive the cartridge assembly and the substrate protecting body and surround the cartridge assembly and the substrate protecting body; and a cover capable of being combined to the casing.

Claims

1. A battery module comprising:

a cartridge assembly including a plurality of cartridges configured to receive a battery cell;

a substrate protecting body combined to the cartridge assembly;

a casing configured to receive the cartridge assembly and the substrate protecting body and surround the cartridge assembly and the substrate protecting body; and

a cover capable of being combined to the casing,

wherein the casing, comprises a first bent unit bent in a predetermined direction and the substrate protecting body comprises a second bent unit bent to correspond to the first bent unit.

2. The battery module of claim 1, wherein the first bent unit and the second bent unit are arranged close to each other so that, when the casing moves, the first bent unit is configured to contact the second bent unit and limit a movement range of the casing.

3. The battery module of claim 1, wherein at least one of the first bent unit and the second bent unit comprises a round portion.

4. The battery module of claim 1, wherein the first bent unit and the second bent unit are in a symmetrical form.

5. The battery module of claim 1, wherein an insertion hole for inserting a bushing member to which a fastening member is combined is formed in the substrate protecting body.

6. The battery module of claim 5, wherein, when the bushing member is inserted into the insertion hole, the substrate protecting body is arranged between the bushing member and the casing.

7. The battery module of claim 1, wherein the substrate protecting body includes a plastic material.

8. A battery pack comprising the battery module according to claim 1.

9. An automobile comprising the battery module according to claim 1.
