Assembly type battery pack bracket of hoisting type battery replacing vehicle

Abstract

The embodiment of the invention provides an assembly type battery pack bracket of a hoisting type battery replacing vehicle, the battery pack bracket comprises a first body, a battery pack lock, a first reinforcing piece and a connecting piece, the battery pack lock is arranged on one side of the first body in the thickness direction and is used for fixing a battery pack; the first reinforcing piece is arranged on the other side of the first body in the thickness direction; the connecting piece is connected with the first reinforcing piece, and the first reinforcing piece is connected with a large frame of the hoisting type battery replacing vehicle through the connecting piece. The battery pack bracket provided by the embodiment of the invention is detachable, the technical defect that the battery pack bracket is easy to deform in the prior art is overcome, the overall smoothness of the battery pack bracket is ensured, and meanwhile, the battery pack bracket in the embodiment ensures the normal action of the locking structure and the normal battery replacement function.

Description

technical field [0001] The invention relates to the technical field of battery pack fixing, in particular to an assembled battery pack bracket of a hoisting battery exchange vehicle. Background technique [0002] Lithium-ion batteries and new energy electric vehicles have gradually matured and developed rapidly in the past ten years. Electric energy is the main alternative energy source for vehicles in the future, because electric energy can be converted from various clean and renewable energy sources such as solar energy, water energy, wind energy, and nuclear energy. At the same time, the use of electric energy can also reduce dependence on non-renewable energy sources such as petroleum . With the concept of environmental protection, low-carbon economy, and energy consumption reduction being valued by people, the automobile industry is facing increasingly severe challenges due to a series of negative effects such as exhaust emissions polluting the environment and high ene...

Problems solved by technology

The basic working principle of battery pack replacement for mining trucks and long-distance heavy trucks is that after the vehicle arrives at the designated area, the station control system issues an instruction, the battery pack locking mechanism opens and locks, the hoisting battery swapping mechanism performs battery swapping, and the battery pack is locked after the swapping is complete. The mechanism is closed and locked to complete the battery replacement, but mining trucks and long-distance heavy trucks have the characteristics of continuous working hours, poor working road conditions, and high work intensity. The battery pack bracket is torn and overall deformed at the bracket connection position due to vibration and fatigue deformation. It is the main factor affecting the normal replacement and use of vehicles

[0005] The existing battery pack bracket is integrally welded. The battery pack bracket and connectors are welded to form an integrated structure. The battery pack bracket is connected to the vehicle through transverse bolts as a whole. The battery pack bracket caused by vibration during the operation of the vehicle Uneven stress can easily cause the welding interface between the bracket and the connector to tear, resulting in damage to the overall battery pack bracket, and the locking structure cannot be used normally, affecting normal battery replacement and operation
