  • lattice-truss ribs 100 are formed on the outer walls (excluding the cover surface 30) of at least the top surface 40, the first side surface 50, the second side surface 60, and the third side surface 70, thereby increasing the strength of the outer walls of the storage battery module 10.
  • the fixing surface 20 is also formed with lattice truss ribs 100. This increases the strength of the outer wall of the fixing surface 20. This makes it possible to form a sturdy fixing surface 20.
  • Figures 3 and 4 show the shape of the lattice truss ribs 100 that are regularly formed on the first side surface 50 that faces the cover surface 30.
  • the lattice truss ribs 100 have diamond-shaped ribs 120 provided on the inside of the lattice-shaped ribs 110.
  • the lattice truss ribs 100 are formed on the first side surface 50, the second side surface 60, and the third side surface excluding the cover surface 30, and on the top surface 40.
  • the structure of the storage battery module 10 exhibits the effect of reducing loads and deformations caused by vibration.
  • the lattice truss ribs 100 have approximately the same size and are regularly arranged on the outer wall of the first side surface 50.
  • a reinforcing shape with diamond-shaped ribs 120 on the inside of the lattice ribs 110, it is possible to increase the strength and rigidity compared to a structure consisting of only the lattice ribs 110.
  • the shape is difficult to bend with respect to a load toward the first fixing portion 50a (load from the outside in the X direction on the left and right in Fig. 3).
  • the fixing portions 60a, 70a of the second side surface 60 and the third side surface 70 are also shaped to be less likely to bend when subjected to a load (load from the outside in the Y direction) toward the fixing portions 60a, 70a. This eliminates the risk of deformation or damage to the built-in battery cells.
  • each lattice truss rib 100 is designed to be folded or compressed toward the center where the first fixing portion 50a is located. That is, the lattice rib 110 is shaped so that its width narrows toward the center (on the Z axis of the first fixing portion 50a). Therefore, the diamond-shaped rib 120 formed inside the lattice rib 110 is shaped so that it becomes smaller toward the center where the first fixing portion 50a is located.
  • the shape of the lattice truss rib 100 As shown in Figure 4, it is possible to further increase the strength and rigidity. As a result, even if the storage battery module 10 mounted on an electric vehicle is subjected to vibration, deformation as shown in Figure 8 can be prevented. In other words, the shape is even less likely to bend when subjected to a load toward the center where the first fixing portion 50a is located. Therefore, there is no risk of deformation or damage to the built-in battery cells.
  • FIG. 5(a) is an enlarged view of frame 20a in FIG. 2, showing the truss shape formed in first fixing portion 50a.
  • FIG. 5(b) shows a cross-sectional view taken along line A-A in FIG. 5(a).
  • first fixing portion 50a is shown as an example, but the second fixing portion 60a and third fixing portion 70a may also adopt the same shape.
  • the structure has truss ribs 150 formed on the outer periphery (X direction) of the first fixed portion 50a, extending in the depth direction (Z direction).
  • the truss ribs 150 have a triangular shape as a basic unit, and are formed so as to become smaller in the X direction toward the first fixed portion 50a. This makes it possible to suppress bending of the ribs in the first fixed portion 50a, where stress concentration is high, and reduce the load.
  • by adding truss ribs 150 in the Z direction, which is perpendicular to the X direction in which stress is applied deformation can be suppressed.
  • the first fixed portion 50a where stress is concentrated, is reinforced more rigidly, making it less likely to bend.
  • Fig. 6(a) shows a B-B cross-sectional view of the truss rib 150 of the first fixing portion 50a.
  • Fig. 6(b) shows a CC cross-sectional view of the same position in a storage battery module without the diamond-shaped rib 120 and the truss rib 150 as a comparative example.
  • the two legs are formed by the truss ribs 150, and therefore the cross-sectional area is increased, resulting in a shape that has increased strength against vibration.
  • the cross section is the area of only the lattice ribs 110, and so it can be seen that the cross-sectional area is smaller than that of FIG. 6(a). Therefore, it cannot be said that it has sufficient strength against vibration.
  • the cross-sectional area can be increased. This makes it possible to increase the moment of inertia in the deformation direction. As a result, it becomes more difficult to bend and the rigidity can be increased. In this way, by combining lattice ribs and truss ribs, it is possible to reduce impact and prevent deformation and bending of the module.
  • FIG. 7 is a diagram showing part of the internal structure of the storage battery.
  • the first case 10aa, the second case 10bb, and the battery cells 200 arranged in 5 layers x 2 rows are shown.
  • the lattice truss ribs formed on the outer walls of the first case 10aa and the second case 10bb are not shown.
  • 4 x 2 rows of spacers 210 are integrally formed inside the second case 10bb.
  • Each battery cell 200 is arranged insulated by the spacers 210.
  • the upper surface of each battery cell 200 is covered by the first case 10aa, and the first case 10aa and the second case 10bb are fixed by screws.
  • a bus bar, a wiring board, a top cover that becomes the cover surface 30, and the like are further attached.
  • These structures may be well-known structures such as those described in Japanese Patent No. 6168986, and therefore their description will be omitted.
  • the lattice truss ribs 100 are formed on the outer walls of the first side surface 50, the second side surface 60, the third side surface 70, and the top surface 40, so that the effects of vibration on the battery module 10 can be mitigated.
  • the lattice truss ribs 100 are designed to have the same shape and become smaller as they approach the fastening points where stress concentration is high, so that the load can be reduced.
  • the truss ribs 150 of the fixing part are designed perpendicular to the sliding surface at the fixing position, so that the strength in the vertical direction of the fixing part can be increased and resistance to bending can be exerted.
  • the storage battery module of the embodiment is a storage battery module 10 including a plurality of battery cells 200 and a box-shaped case in which the battery cells 200 are stored.

  • the strength of the entire storage battery module can be increased and the rigidity can be increased.
  • deformation can be suppressed even if the storage battery module 10 is subjected to vibration.
  • the storage battery module of this embodiment is configured such that lattice truss ribs 100 of the same size are formed regularly on the outer wall of the first side surface 50 that faces the cover surface 30. This makes it possible to suppress deformation even if the storage battery module 10 is subjected to vibrations when placed on an electric vehicle, for example.
  • the storage battery module of the embodiment is provided with a fixing portion 50a that extends from the end of the first side surface 50 to the fixing surface 20 for fixing, and the lattice truss ribs 100 are formed on the outer wall of the first side surface 50 facing the cover surface 30 so that they become gradually smaller in size in the direction in which the fixing portion 50a is located.
  • the battery module of this embodiment is configured such that lattice truss ribs 100 are regularly formed on the outer wall of the fixing surface 20. This increases the strength of the fixing surface 20 and increases its rigidity.
