[0002] Light-duty mining dump trucks are one of the key pieces of equipment in earthmoving construction and open-pit mines. With the continuous development of new energy technologies and in order to achieve the development of green mining and the construction of green mines, pure electric mining dump trucks have emerged. The battery box brackets suspended on both sides of the chassis are key components of pure electric mining trucks, typically used to mount the power battery box. Pure electric mining trucks operate in harsh environments, experiencing significant impacts and vibrations during operation. Furthermore, the power battery and the total weight of the battery box are substantial, thus placing higher demands on the reliability and safety performance of the battery box bracket assembly.

[0003] In existing products, the battery box bracket mounting surface and the vehicle frame mounting surface are large in overall size and have welding deformation, resulting in an error in the overall flatness of the two. After assembly, the two cannot fit completely together and there is a gap. When the vehicle frame and battery box bracket are subjected to large impacts or vibrations, the bracket mounting bolts are subjected to large vertical shear forces, which can cause them to loosen and break. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an installation structure for battery box brackets and vehicle frames, which can avoid the problem of loosening and breaking of bolts, and greatly improve the assembly reliability and safety of battery box brackets.

[0005] This utility model is achieved according to the following technical solution:

[0006] In a first aspect, this utility model provides a mounting structure for a battery box bracket and a vehicle frame, comprising:

[0007] The frame panels are fixed to the outer vertical surface of the frame. The number of these panels is the same as the number of battery bracket vertical beams, and one frame panel corresponds to one battery bracket vertical beam.

[0008] The number of battery bracket mounting plates is the same as the number of frame plates, and they are connected to the corresponding frame plates by detachable fasteners. The battery bracket vertical beam is fixed to the outer side of the corresponding battery bracket mounting plate. A limiting structure is provided between the side surfaces of the battery bracket mounting plate and the frame plate facing each other to prevent the battery bracket mounting plate from moving vertically downward.

[0009] At least one support is installed between the bottom surface of the vehicle frame and the rear plate of the battery bracket to limit the vertical upward movement of the battery bracket mounting plate.

[0010] In some embodiments, the outer side of the frame panel is a stepped surface with a concave top and a convex bottom, and the inner side of the battery bracket mounting plate is a stepped surface with a convex top and a concave bottom; the frame panel and the battery bracket mounting plate are attached together, and the stepped parts of the two are engaged together to form the limiting structure.

[0011] In some embodiments, the vehicle frame plate has circumferential threaded holes, and the battery bracket mounting plate has circumferential through holes, with one through hole corresponding to one threaded hole, and the two are coaxially arranged. The battery bracket mounting plate is fixed to the vehicle frame plate by circumferential bolts used as detachable fasteners.

[0012] In some embodiments, the bottom surface of the battery bracket mounting plate has a bevel for welding to the rear plate of the battery bracket.

[0013] In some embodiments, the battery bracket mounting plate extends outward horizontally on one side of the portion connected to the rear plate of the battery bracket to form a triangular protrusion, thereby increasing the connection width with the rear plate of the battery bracket.

[0014] In some embodiments, the side facade of the support base is welded to the inner facade of the rear panel of the battery bracket, and during welding, the top surface of the support base is in contact with the bottom surface of the vehicle frame.

[0015] In some embodiments, the support base consists of an L-shaped plate and at least one reinforcing rib plate welded to the L-shaped plate; the L-shaped plate is provided with at least one welding hole for welding together with the rear plate of the battery bracket and at least one weight reduction hole.

[0016] In some embodiments, the central region of the frame panel is provided with at least one welding hole for welding to the outer facade of the frame.

[0017] Secondly, this utility model provides a pure electric mining vehicle, including a frame and a battery box bracket, wherein the battery box bracket is assembled on the frame through the aforementioned mounting structure for mounting the battery box bracket to the frame.

[0018] In some embodiments, a symmetrically arranged battery box bracket is installed on each side of the vehicle frame.

[0019] The beneficial effects of this utility model are:

[0020] This utility model restricts the vertical movement of the battery box bracket through a stepped structure and a support base. When the vehicle frame and battery box bracket are subjected to large impacts or vibrations, the stepped structure and support base can greatly share the large vertical shear force on the bracket mounting bolts, thereby avoiding the problem of bolt loosening and breakage, and greatly improving the assembly reliability and safety of the battery box bracket.

[0034] As can be seen from the above, this utility model can greatly reduce the vertical shear force on the bracket mounting bolts through the limiting structure and support base, thereby avoiding the problem of bolt loosening and breakage, and greatly improving the assembly reliability and safety of the battery box bracket.

[0035] The following provides a further explanation of the specific structure of the aforementioned limiting structure.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, the outer side of the frame panel 3 is a stepped surface with a concave top and a convex bottom, and the inner side of the battery bracket mounting plate 1 is a stepped surface with a convex top and a concave bottom; the frame panel 3 and the battery bracket mounting plate 1 are attached together, and the stepped parts of the two are engaged together to form a limiting structure 8.

[0040] Further options, such as Figure 1 , Figure 3 As shown, the bottom surface of the battery bracket mounting plate 1 has a bevel for welding together with the rear plate 5 of the battery bracket.

[0041] Further options, such as Figure 1 , Figure 3 As shown, the battery bracket mounting plate 1 extends outward horizontally on one side of the part connected to the battery bracket rear plate 5 to form a triangular protrusion, increasing the connection width with the battery bracket rear plate 5.

[0042] The following provides a further explanation of the specific structure of the aforementioned support base.

[0043] like Figure 4 , Figure 5 As shown, the side facade of the support base 6 is welded to the inner facade of the battery bracket rear plate 5. During welding, the top surface of the support base 6 is in contact with the bottom surface of the frame 4. The support base 6 consists of an L-shaped plate and at least one reinforcing rib welded into the L-shaped plate. The L-shaped plate has at least one welding hole for welding to the battery bracket rear plate 5 and at least one weight-reducing hole. Specifically, the L-shaped plate has one rectangular welding hole and one circular weight-reducing hole, and two reinforcing ribs are welded into the L-shaped plate.
