[0034] Example 1

[0035] Hybrid mining trucks refer to mining dump trucks that use a hybrid power system. This type of vehicle combines two power sources, a traditional internal combustion engine (such as a diesel engine) and an electric motor, to improve energy efficiency, reduce emissions, and enhance operating performance. In a mining operation environment, hybrid mining trucks can achieve energy conservation and emission reduction by optimizing the working mode of the power system and switching or combining the internal combustion engine and the electric motor under different working conditions.

[0036] Reference Figure 1-Figure 4 The present embodiment provides a power battery box (hereinafter referred to as the box) of a hybrid mining truck, including a battery frame 100, side panels 2 are respectively arranged on opposite sides of the battery frame 100, a wire guard 1 is arranged on one side of the side panel 2, and the wire guard 1 is used to accommodate and guide the high-voltage wire harness, and a connecting plate 3 is arranged on the other side of the side panel 2, and the connecting plate 3 is used to connect the sub-frame and the frame longitudinal beam. The entire box is respectively formed with an A area and a B area corresponding to the middle and upper part of the connecting plate 3, and the A area is located above the B area (such as Figure 3 ). The box body can be installed on the side of the frame as a whole, and the area corresponding to area A on the connecting plate 3 is used to be connected and fixed with the subframe by bolts, and the area corresponding to area B is used to be connected and fixed with the frame longitudinal beam by bolts. Since the side of the frame has a large space, installing the box body on the side of the frame can solve the problem of arranging the power battery box body in a small space.

[0037] Wire guards 1 are installed on both sides of the box. The wire guards 1 can be used for the routing of high-voltage wire harnesses with a large bending radius. The wire guards 1 are designed on both sides of the box to maximize the wiring space of the box and provide more possibilities for placing different boxes. After the box is installed, the wire guards 1 are located away from the side of the frame longitudinal beam, which is conducive to assembly and convenient for later disassembly and maintenance.

[0038] The two side panels 2 of the power battery box are designed to be lightweight to reduce the weight of the power battery box and improve the economy of the vehicle. Specifically: the two side panels 2 of the power battery box are designed to be lightweight hollow structures 201. Figure 1 and Figure 4 As shown, the hollow structure 201 includes a plurality of waist-shaped high-voltage wire harness through holes 2012, a plurality of triangular holes 2011, a plurality of parallelogram holes 2013, and a plurality of lightweight circular holes 2014. Among them, the triangular hole 2011 is a right-angled triangular hole 2011, and one of the right-angled sides of the right-angled triangular hole 2011 is horizontally arranged; one of the sides of the parallelogram hole 2013 is horizontally arranged, and one of the angles of the parallelogram hole 2013 is 45°, and each angle of the triangular hole 2011 and the parallelogram hole 2013 is chamfered. That is, the triangular hole 2011 and the parallelogram hole 2013 are both designed at 45 degrees, so the shear stress of the two side panels 2 on the oblique section with an inclination angle of 45° is the maximum value, that is, the shear stress that the power battery box can bear is the maximum.

[0039] A multi-layer battery bracket 5 is arranged on the inner side of the side panel 2. The battery bracket 5 is a rectangular plate, that is, the longitudinal section of the battery bracket 5 is L-shaped. The battery bracket 5 includes two vertically connected plate bodies, one of which is fixed to the side panel 2 by multiple bolts, and the other plate body serves to support the sliding bracket 7.

[0040] Preferably, the battery bracket 5 in this embodiment is designed to have four layers. Figure 1 and Figure 2 shown.

[0041] The two battery brackets 5 on opposite sides of each layer support a plurality of sliding brackets 7 arranged parallel to each other, the length direction of the sliding brackets 7 is perpendicular to the length direction of the battery brackets 5 , and the sliding brackets 7 can slide horizontally on the battery brackets 5 .

[0042] Preferably, each battery bracket 5 is provided with a guide rail, the guide rail and the battery bracket 5 are connected and fixed by a plurality of bolts, and guide grooves matching the guide rails are respectively provided at both ends of the sliding bracket 7. Specifically, the guide rail is U-shaped, and two guide grooves matching the U-shaped guide rails are provided at the ends of the sliding bracket 7, and the guide rails are correspondingly inserted into the guide grooves of the sliding bracket 7, so that the sliding bracket 7 can move laterally along the guide rails.

[0043] In this embodiment, a plurality of shock absorbing modules 6 are arranged on the sliding bracket 7. Specifically, the shock absorbing module 6 adopts fixed-point shock absorbing blocks, and fixed-point shock absorbing blocks are arranged at both ends of each sliding bracket 7. By arranging a plurality of fixed-point shock absorbing blocks, the problem of fatigue damage of the power battery due to vibration under harsh working conditions is solved. When assembling the power battery into the box, the power battery can be assembled on the sliding bracket 7 in advance, and then the sliding bracket 7 and the power battery are pushed into the box together, which improves the installation efficiency of the power battery and facilitates the maintenance of the power battery in the later stage. The connecting plate 3 of the power battery box is connected to the frame longitudinal beam and the subframe in turn, which enhances the overall stability of the chassis and the power battery box.

[0044] Reinforcing ribs 4 are provided at the corners of the connecting plate 3 and the side plate 2 . The reinforcing ribs 4 are L-shaped reinforcing plates and are respectively welded and fixed to the inner side surface of the connecting plate 3 and the outer side surface of the side plate 2 , thereby improving the structural strength of the power battery box.

[0045] Furthermore, the battery box cross beam and the battery cover are fixed to the power battery box by bolts respectively.

[0050] 2. The connecting plate 3 is located on a side close to the longitudinal beam of the frame, while the wire guard 1 is installed on a side away from the longitudinal beam of the frame, which is convenient for assembly and later disassembly and maintenance.

[0051] 3. Both side panels 2 of the power battery box adopt a lightweight design, which reduces the weight of the power battery box and improves the economy of the vehicle.

[0052] 4. The lightweight hollow structure 201 of the two side panels 2 of the power battery box adopts a 45-degree design. Then, the shear stress of the two side panels 2 at the inclined section with an inclination angle of 45° is the maximum, that is, the shear stress that the power battery box can bear is the maximum.

[0053] 5. Multiple fixed-point shock-absorbing blocks are arranged on each layer of the sliding bracket 7 of the power battery box, which solves the problem of fatigue damage of the power battery due to vibration under harsh working conditions.

[0054] 6. The sliding bracket 7 can be assembled with the power battery in advance, and then pushed into the box as a whole, which improves the efficiency of power battery installation and facilitates the later maintenance of the power battery.

[0055] 7. The connecting plate 3 of the power battery box is connected to the frame longitudinal beam and the subframe in turn, which enhances the overall stability of the chassis and the power battery box.

[0056] 8. The connecting plate 3 of the power battery box is welded and fixed to the two side plates 2 through the reinforcing ribs 4, thereby improving the structural strength of the power battery box.

[0057] The beneficial effects of the technical solution of the present invention are:

[0058] In the present application, a connecting plate 3 and a wire guard 1 are respectively arranged on the opposite sides of the side panel 2. The power battery box can be installed on the side of the frame longitudinal beam and the subframe through the two connecting plates 3. The wire guards 1 are installed on both sides of the box. The wire guards 1 can be used for routing high-voltage wire harnesses with a large bending radius. The wire guards 1 are designed on both sides of the box to maximize the wiring space of the box and provide more possibilities for placing different boxes. After the box is installed, the wire guard 1 is located away from the side of the frame longitudinal beam, which is conducive to assembly and convenient for later disassembly and maintenance. Since the side of the frame has a large space, installing the box on the side of the frame can solve the problem of arranging the power battery box in a small space.

[0059] A plurality of fixed-point shock-absorbing blocks are arranged on each layer of the sliding bracket 7 of the power battery box, so as to solve the problem of fatigue damage of the power battery due to vibration under harsh working conditions.

[0060] The sliding bracket 7 can be assembled with the power battery in advance, and then pushed into the box as a whole, which improves the installation efficiency of the power battery and facilitates the later maintenance of the power battery.
