[0033] As Figure 1 , Figure 2 and Figure 3 shown, the battery box provided by the embodiments of the present utility model includes a side beam assembly 100 and a plurality of channel beam assemblies 200. The side beam assembly 100 encloses an installation cavity 110. The plurality of channel beam assemblies 200 are sequentially arranged in the installation cavity 110 along the length direction of the side beam assembly 100. Each channel beam assembly 200 includes a first channel beam 210. The beam bottom plate 250 of the first channel beam 210 is arranged perpendicular to the length direction of the side beam assembly 100, and the beam wall plates 260 of the first channel beam 210 are arranged along the width direction of the side beam assembly 100 and are connected to the side beam assembly 100.

[0034] The battery box of the embodiments of the present utility model provides a battery box for mining trucks. The side beam assembly 100 serves as the main external configuration structure of the battery box, and the channel beam assembly 200 serves as the main internal configuration structure of the battery box. The side beam assembly 100 can form a cuboid frame. Therefore, the length direction, width direction, and height direction of the side beam assembly 100 are perpendicular to each other pairwise. The side beam assembly 100 encloses an installation cavity 110, and the channel beam assembly 200 is arranged in the installation cavity 110. The channel beam assembly 200, on the one hand, constitutes the positioning and support for the battery, and on the other hand, plays a role in the structure of the battery box.

[0035] The channel beam assembly 200 includes a first channel beam 210. The channel beam structure includes a beam bottom plate 250 and two beam wall plates 260. The two beam wall plates 260 are respectively connected to both sides of the beam bottom plate 250 to form a channel-shaped beam. The beam bottom plates 250 of the plurality of first channel beams 210 are sequentially arranged along the length direction of the side beam assembly 100, that is, the beam bottom plate 250 of the first channel beam 210 is arranged on the cross-section of the side beam assembly 100 perpendicular to the length direction of the side beam assembly 100. The beam wall plates 260 of the first channel beam 210 are respectively located at the upper and lower ends of the beam bottom plate 250. The extending direction of the beam wall plates 260 is the width direction of the side beam assembly 100 and is connected to the side beam assembly 100.

[0036] The utility model uses a channel beam as the internal support beam of the battery box, which improves the strength of the battery box to solve the problem of low local strength of the battery box after the number of batteries in the mining truck increases. Batteries can be installed between two adjacent channel beam assemblies 200. When the number of batteries increases, only the number of channel beam assemblies 200 needs to be increased in the installation cavity 110 of the side beam assembly 100. The structure is simple, the assembly is convenient, the adaptability is high, and modular assembly can be realized.

[0037] According to an embodiment provided by the utility model, the channel beam assembly 200 further includes a second channel beam 220. The notch of the first channel beam 210 is opposite to that of the second channel beam 220. The beam bottom plate 250 of the first channel beam 210 is attached to and connected with the beam bottom plate 250 of the second channel beam 220. The beam wall plate 260 of the second channel beam 220 is arranged along the width direction of the side beam assembly 100 and is connected with the side beam assembly 100.

[0038] In this embodiment, the channel beam assembly 200 is composed of a first channel beam 210 and a second channel beam 220. The second channel beam 220 has the same structure as the first channel beam 210, and also forms a trough shape by connecting two beam wall plates 260 at both ends of the beam bottom plate 250. The beam bottom plates 250 of multiple second channel beams 220 are arranged in sequence along the length direction of the side beam assembly 100, that is, the beam bottom plate 250 of the second channel beam 220 is arranged on the cross-section of the side beam assembly 100 perpendicular to the length direction of the side beam assembly 100. The beam wall plates 260 of the second channel beam 220 are respectively located at the upper and lower ends of the beam bottom plate 250. The extending direction of the beam wall plate 260 is the width direction of the side beam assembly 100 and is connected with the side beam assembly 100.

[0039] The beam bottom plate 250 of the first channel beam 210 is opposite to the beam bottom plate 250 of the second channel beam 220, and the notches are arranged in opposite directions. The bottom surfaces of the two beam bottom plates 250 are attached and connected into one body, that is, the first channel beam 210 and the second channel beam 220 are symmetrically arranged. Thus, the shape of the cross-section of the channel beam assembly 200 perpendicular to the width direction of the side beam assembly 100 is H-shaped. Through the structural design of the channel beam assembly 200 with the first channel beam 210 and the second channel beam 220 back to back, the thickness of the beam bottom plate 250 of a single channel beam assembly 200 is increased, and the connection position between the channel beam assembly 200 and the side beam assembly 100 is increased, thereby improving the stiffness of the battery box.

[0040] In this embodiment, the channel beam assemblies 200 on both side surfaces in the length direction of the side beam assembly 100 are both composed of the first channel beam 210. The channel beam assemblies 200 in the installation cavity 110 between the two side surfaces are both composed of the first channel beam 210 and the second channel beam 220. The space between two adjacent channel beam assemblies 200 is used for positioning and installing batteries.

[0041] In the prior art, in a battery box body formed by welding steel plates, the channel beams for the box body are not light-weighted, resulting in a heavy battery box body, increasing the vehicle's overall mass and greatly reducing the vehicle's economy.

[0042] According to an embodiment provided by the present utility model, at least one of the beam bottom plates 250 of the first channel beam 210 and the beam bottom plates 250 of the second channel beam 220 is provided with a hollowed-out portion 300. In this embodiment, by providing the hollowed-out portion 300 on the beam bottom plate 250 of the channel beam assembly 200, the overall weight of the channel beam assembly 200 can be reduced, thereby achieving the effect of light-weighting the channel beam, reducing the vehicle's overall mass and improving the vehicle's economy.

[0043] In this embodiment, the hollowed-out portion 300 on the beam bottom plate 250 of the first channel beam 210 is symmetrically arranged with the hollowed-out portion 300 on the beam bottom plate 250 of the second channel beam 220. The hollowed-out portions 300 of each channel beam assembly 200 are correspondingly arranged.

[0044] In the prior art, in a battery box body formed by welding steel plates, although the channel beams for the box body are light-weighted, the shear stress that the channel beams can bear is not at the maximum critical point, and the bearing capacity of the channel beams is low.

[0045] According to an embodiment provided by the present utility model, the hollowed-out portion 300 at least includes an angle of 45° with the width direction of the side beam assembly 100. In this embodiment, the hollowed-out portion 300 is in a shape with an angle of 45°, that is, a structure with an inclination angle of 45° can be formed on the beam bottom plate 250. Thus, on the 45° inclined cross-section, the shear stress is the maximum, that is, the shear stress that the channel beam can bear is the largest. While realizing the light-weighted channel beam assembly 200, the structural strength of the battery box is further improved.

[0046] In this embodiment, the composition shapes and quantities of the hollowed-out portions 300 on each channel beam assembly 200 are the same. In the width direction of the side beam assembly 100, one hollowed-out portion 300 is composed of two isosceles triangles and a parallelogram. The parallelogram is arranged between the two isosceles triangles. The isosceles triangles are right-angled isosceles triangles, and the parallelogram is a parallelogram with a diagonal angle of 45° to match the right-angled isosceles triangles.
