Adjustable battery pack locking mechanism suitable for hoisting type battery replacing vehicle

Abstract

The invention provides an adjustable battery pack locking mechanism suitable for a hoisting type battery replacing vehicle. The adjustable battery pack locking mechanism comprises an adjustable locking mechanism assembly, which is arranged on the battery pack bracket through a connecting plate and at least comprises a locking executing mechanism and a first adjustable mechanism, and the locking executing mechanism is arranged on the battery pack bracket through the first adjustable mechanism; an adjustable locking pressure plate device, which is arranged on a battery pack frame, and the battery pack frame is arranged on the battery pack bracket, wherein the adjustable locking pressing plate device at least comprises a locking pressing plate and a second adjustable mechanism, and wherein the locking pressure plate is connected with the battery pack frame, and the position of the locking pressing plate is adjusted between the locking executing mechanism and the battery pack frame through the second adjustable mechanism. When a vehicle vibrates during running and the battery pack bracket deforms, the locking mechanism cannot be unlocked or locked, or the battery pack frame or the battery pack bracket deforms greatly, the normal use of the locking mechanism is guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery pack fixing, in particular to an adjustable battery pack locking mechanism suitable for hoisting battery exchange vehicles. Background technique [0002] Lithium-ion batteries and new energy electric vehicles have gradually matured in the past ten years and have developed rapidly in our country. 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, and it can also reduce the country's 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 environmen...

AI Technical Summary

Problems solved by technology

Due to the deformation of the battery pack frame or the battery pack bracket, the change of the gap between the lock and the lock plate causes problems such as the lock cannot be opened, the lock cannot be locked, and the gap is too large, etc., which can only be adjusted by changing the thickness of the lock plate. Each battery pack has 6-8 locking pressure plates, the thickness of each pressure plate is inconsistent due to deformation, resulting in frequent maintenance and many spare parts models

Moreover, the existing locking assembly and the battery pack bracket are connected by welding, and the lock cannot be opened due to the failure of the locking mechanism, the deformation of the battery pack frame or the battery pack bracket, and the change in the gap between the lock and the locking pressure plate. The battery pack and the battery pack bracket need to be disassembled for maintenance. Because the overall weight of the battery pack and the battery pack bracket is large, the operation risk is high, the maintenance takes a long time, and the maintenance is difficult
