Fig. 1a is a perspective view of a battery module according to an embodiment of the present invention, and fig. 1b is a perspective view of a frame according to an embodiment of the present invention.
The battery module 1 may include a frame 2. The frame 2 may define the outer circumference of the battery module 1.
The frame 2 may be provided to accommodate a secondary battery. The frame 2 may define the outer circumference of the battery module 1 in a shape surrounding the secondary battery. In other words, the battery module 1 may include the frame 2, and the frame 2 may surround the secondary battery while defining the outer circumference of the battery module.
Referring to fig. 1, the frame 2 may have a "U" shape, but is not particularly limited thereto.
The frame 2 may comprise a bottom 10. For example, referring to fig. 1, the base 10 may be disposed on an XY plane. The bottom 10 may support the secondary battery when the secondary battery is accommodated in the frame 2.
The frame 2 may comprise side portions 20. For example, referring to fig. 1, the side portion 20 may be disposed to extend in the +z direction on the XY plane. When the secondary battery is accommodated in the frame 2, the inner surface 21 of the side 20 may face the secondary battery.
The inner surface 21 may include an edge portion 22. The edge portion 22 may be defined as a predetermined range from the edge end portion to other than the edge end portion of the inner surface 21. In other words, the edge portion 22 may include a portion provided with guide rails (e.g., reference numerals 110 and 120) to be described later.
The bottom 10 and the side 20 may define an inner space (accommodation space) accommodating the secondary battery.
The insulating sheet 200 may be attached to the inner surface 21 of the side portion 20. If an error occurs or the insulating sheet is irregularly disposed every time the insulating sheet 200 is attached to the edge portion 22, the insulating function may deteriorate or interference with other components may occur. Accordingly, when attaching the insulating sheet 200, a guide rail for precisely attaching the insulating sheet 200 to a predetermined position while minimizing an error may be required.
The insulating sheet 200 may be attached along guide rails (e.g., reference numerals 110 and 120) provided on the edge portion 22 to be described in detail later.
Fig. 2 is an enlarged view of a guide rail according to an embodiment of the present invention.
The frame 2 may include a first rail 110. The first guide rail 110 may be provided to guide the attachment of the insulation sheet 200. For example, the insulating sheet 200 may be attached along the first guide rail 110.
The frame 2 may include a second rail 120. The second guide rail 120 may be provided to a second length L2 different from the first length L1 of the first guide rail 110.
The first rail 110 and the second rail 120 may protrude from the inner surface 21. For example, the first rail 110 and the second rail 120 are provided on the inner surface 21, and may protrude toward the inner space.
The second rail 120 may be parallel to the first rail 110.
The second rail 120 may be disposed at a height different from that of the first rail 110. For example, the first rail 110 may have a height higher than that of the second rail. The height may be based on the height of the base 10. Referring to fig. 2, the first height H1 of the first guide rail 110 may be higher than the second height H2 of the second guide rail 120.
The first rail 110 and the second rail 120 may constitute the rail group 100. The plurality of rail groups 100 may be disposed on the edge portion 22 of the inner surface 21 on which the insulation sheet 200 is attached. For example, the guide rail groups 100 may be provided at four portions of the edge portion 22 of the inner surface 21, respectively. However, embodiments of the inventive concept are not so limited.
Fig. 3 is an enlarged view showing a state in which an insulating sheet is attached based on a guide rail according to an embodiment of the present invention.
The insulating sheet 200 may be attached to the frame 2.
The insulating sheet 200 may be attached not to exceed the first height H1 of the first guide rail 110. For example, the first guide rail 110 may be an upper limit to which the insulating sheet 200 can be attached.
The insulation sheet 200 may be attached along the first guide rail 110. For example, the insulating sheet 200 may be attached in a direction in which the first rail 110 extends.
The attachment position of the insulating sheet 200 may be selectively determined by the length difference LD between the first length L1 and the second length L2. For example, the insulating sheet 200 may be attached to a position where the second rail 120 covers, and may be attached to cover an end of the first rail 110 further away from the end of the rail 120 from the length difference LD. In other words, the insulating sheet 200 may be attached in two directions (e.g., +y direction and-Y direction) along the Y axis based on the first rail 110 and the second rail 120.
The insulating sheet 200 may cover the second rail 120. For example, the insulating sheet 200 may be attached while covering at least a portion of the second rail 120. In addition, the insulating sheet 200 may be attached to the inner surface 21 while covering the second rail 120 at the second height H2 from the bottom 10. The insulating sheet 200 may be attached to the inner surface 21 at a first height H1 from the bottom 10 while covering the second rail 120. In other words, the insulating sheet 200 may be attached in two directions (e.g., +z direction and-Z direction) along the Z axis based on the first rail 110 and the second rail 120.
As described above, the insulating sheet 200 may be guided in four directions (e.g., +y and-Y directions and +z and-Z directions) of two axes (e.g., Y and Z axes) based on the first and second rails 110 and 120. Accordingly, since the insulating member 200 is attached to a predetermined position, insulating performance can be improved, and the insulating member 200 can be attached quickly and efficiently.
Fig. 4 is an enlarged view showing a state in which a guide rail and an insulating sheet are attached to the guide rail according to another embodiment of the present invention.
The first rail 110a may be disposed to vary in a direction transverse to the height direction from the second rail 120 a. For example, the first guide rail 110a may extend in a direction inclined with respect to the height direction (e.g., HD1, HD2, and HD3 directions). Accordingly, the height difference (e.g., HD1, HD2, HD 3) between the first rail 110a and the second rail 120a may vary in a predetermined direction (e.g., -Y direction).
The insulating sheet 200a may be attached in an inclined direction in which the first guide rail 110a extends.
The insulating sheet 200a may be selectively attached to have a height difference LDa in the +y direction and the-Y direction. In other words, the first guide rail 110a and the second guide rail 120a may guide the insulating sheet 200a in two directions based on the Y axis.
The insulating sheet 200a may be selectively attached to have a height difference (e.g., HD1, HD2, and HD 3) in the +z direction and the-Z direction. In other words, the first guide rail 110a and the second guide rail 120a may guide the insulating sheet 200a in two directions based on the Z axis. The first guide rail 110a and the second guide rail 120a may guide the insulating sheet 200a to be attached at least three heights in the Z-axis direction.
As described above, the insulating sheet 200a may be guided in four directions (e.g., +y and-Y directions and +z and-Z directions) of two axes (e.g., Y and Z axes) based on the first and second rails 110a and 120 a. The first guide rail 110a and the second guide rail 120a may guide the insulating sheet 200a to be attached at least three heights in the Z-axis direction. Accordingly, since the insulating member 200a is attached to a predetermined position, insulating performance can be improved, and the insulating member 200a can be attached quickly and efficiently.
Although the embodiments of the present invention have been described with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention as defined in the following claims.
