Battery replacing method of battery under rear floor of electric automobile

Abstract

The invention discloses a battery replacing method of a battery under a rear floor of an electric automobile. The battery replacing method comprises the steps that step 1, an electricity lacking battery under the rear floor of the electric automobile is taken out from an automobile body; step 2, a fully charged battery is assembled to an installation station of the battery under the rear floor ofthe electric automobile; the battery replacing method is characterized in that after the electric automobile is parked on a designed battery replacing station of the electric automobile, picking and placing of the battery are achieved depending on a battery replacing mechanical arm of the electric automobile with a lever structure; when the battery is picked and placed, a supporting point of the lever structure is located outside of the electric automobile, a power assisting air cylinder at the outer portion of the supporting point serves as a force application component to apply force to oneend of the lever structure, so that after the other end of the lever structure stretches into the automobile body of the electric automobile in an arc direction and fixes the battery, the lever structure is used for applying the force to take the battery out of the automobile body of the electric automobile in an arc direction. The battery replacing method of the battery under the rear floor of the electric automobile has the advantages that the operation is more convenient, the battery replacing efficiency can be improved, and the collision with a rear door frame and a rear door can be reduced better.

Description

technical field [0001] The invention relates to the technical field of automobiles; in particular, it relates to a method for replacing batteries under the rear floor of an electric automobile. Background technique [0002] Electric vehicles use electricity as energy and are green vehicles. Specifically, the electric vehicle is equipped with a battery, which provides power energy for the electric vehicle. Since the electric energy stored in the electric vehicle battery is certain, the distance that the electric vehicle can travel without charging is limited. In order to enable electric vehicles to travel a longer distance, there are currently some charging stations set up on the side of the road to provide charging for electric vehicles. The charging station is similar to the gas station of ordinary cars. When the battery of the electric vehicle is exhausted or is about to be exhausted, the electric vehicle can charge the battery in the charging station; when the battery i...

Problems solved by technology

[0004] Among them, in the process of transferring under-charged batteries and fully-charged batteries, pure manpower is usually used for transfer. Using pure manpower to complete these two transfer steps has the disadvantages of low automation, low transfer efficiency and high labor intensity. shortcoming

[0005] Moreover, the battery of an electric vehicle is usually installed at the position below the front cover of the vehicle and the position below the rear floor in the compartment of the vehicle. Manpower is used to complete the steps of taking the battery out of the body of the electric vehicle, which will be laborious and inconvenient to take out the battery. shortcoming

[0006] Moreover, when the battery under the rear floor is picked and placed, because the door of the electric vehicle is opened, the range of motion of the corresponding equipment for picking and placing the battery in the horizontal direction will be limited, which is inconvenient to operate.

At the same time, the corresponding equipment used to pick and place the battery is also prone to collision and scratches with the door frame and the car door, which reduces work efficiency and increases labor intensity.
