Description

Technical Field

[0001] The utility model relates to the technical field of accessories for new energy mining dump trucks, and in particular to a power battery fixing device for new energy mining dump trucks. Background Art

[0002] Due to the complexity and harshness of the working environment faced by new energy mining dump trucks, the challenges they face are far more than simple road bumps. These vehicles usually operate under extreme conditions such as unpaved roads, mine tunnels, and steep slopes, resulting in vibration amplitudes far exceeding those of ordinary road vehicles during driving. This high-intensity vibration not only tests the overall structural strength of the vehicle, but also places severe demands on the fixing devices of the power battery.

[0003] As one of the core components of new energy mining dump trucks, the safety and stability of power batteries are directly related to the operating efficiency and operational safety of the vehicle. However, due to the design requirements of the power battery bracket cantilever (usually a longer cantilever is required to accommodate a large battery pack), this area has become the place where vibration is most concentrated. Long-term, high-intensity vibration will not only lead to fatigue accumulation of the bracket material, but may also cause loosening or breakage between structural parts, and then cause the power battery bracket to break. Once the power battery bracket breaks, not only may the battery pack itself be seriously damaged, affecting the vehicle's endurance, but it is more likely to cause a fire or explosion due to internal battery short circuits, electrolyte leakage and other problems, endangering the safety of personnel and equipment. In addition, frequent replacement or repair of battery boxes will greatly increase the operating cost of the vehicle and reduce the overall economic benefits.

[0004] Therefore, in view of the problem that the battery box of the new energy mining dump truck is often damaged, it is necessary to design a fixing device for the power battery to increase the strength of the bracket and reduce the degree of vibration, so as to protect the power battery and realize the safe and efficient production operation of the new energy mining dump truck.
