The lower box 100 includes: a skin layer 106, a filling part 107, and a support structure 103. The skin layer 106 is used to form the surface of the lower box 100. The skin layer 106 is a glass fiber resin composite material with a thickness of one to three millimeters. The skin layer 106 is coated on the surface of the lower box 100 to form a coating space 109; the filling part 107 is filled in the coating space 109 formed by the skin layer 106. The cross section of the lower box 100 forms a sandwich structure in which the skin layer 106 is superimposed on both sides of the filling part 107.

[0030] The filling part 107 is made of polyurethane and is filled by a high-pressure resin transfer molding process, thereby achieving a weight reduction effect.

[0031] In another embodiment, the filling portion 107 is made of polyphenylene ether and is filled by a high-pressure resin transfer molding process (which is a prior art, refer to publication number: CN112976612A).

[0032] Compared with aluminum alloy materials or steel sheet metal materials, glass fiber resin composite materials have lower density, and at the same time, glass fiber resin composite materials have good insulation and corrosion resistance and high performance;

[0033] Compared with the traditional box solution, that is, welding of aluminum alloy profiles, or welding after stamping of steel sheet metal, the solution proposed in this embodiment mainly uses a glass fiber resin composite material as the skin layer 106, and a sandwich structure solution formed by the skin layer 106 and the filling part 107 is integrally formed through a high-pressure resin transfer molding process, thereby achieving the advantages of high performance, weight reduction, insulation, corrosion resistance, reduction in the number of parts, simplified assembly process, and avoidance of welding errors.

[0034] The lower box body 100 has a bottom 113 and a side wall 104, and the side wall 104 is used to connect the upper cover 101 to form a box structure; the liquid cooling plate 105 is attached to the inner side of the bottom 113, and a flow channel for cooling liquid to flow is provided in the liquid cooling plate 105 for cooling the energy storage box.

The support structure 103 includes: a support plate 108 arranged in the covering space 109 and a limiting protrusion 110 fixedly arranged on the inner wall of the covering space 109. The support plate 108 is arranged obliquely and its two ends are respectively abutted against two opposite side walls of the covering space 109. Two adjacent support plates 108 are connected at one end with opposite inclination directions and close to each other to form a protrusion structure 111. The protrusion structure 111 is provided with a limiting groove 112 for the limiting protrusion 110 to be embedded. The support plate 108 is limited by the limiting protrusion 110, and the support plate 108 forms a W-shaped support structure to support the skin layer 106. Thereby, the overall rigidity of the box body is improved.

[0038] A reserved notch 114 is provided on the side wall, the reserved notch 114 opens upward, an embedded part 116 is pre-embedded in the reserved notch 114, and a screw hole for connecting the upper cover 101 is provided on the embedded part 116. A boss 115 is provided on the outer periphery of the embedded part 116. A groove 118 for the boss 115 to be embedded is provided on the side wall of the reserved notch 114.
