Quick battery replacement device for pure electric automobile by employing gas pressure linkage principle

Abstract

The invention discloses a quick battery replacement device for a pure electric automobile by employing a gas pressure linkage principle. A structure of the device includes a placement plate, a chassisframe, an engine bracket, a storage battery, and a connection bracket. When a battery needs to be replaced, air pressure is compressed by driving of a compression button, is introduced in pressure linkage mechanisms in a disassembly mechanism, and is converted by pneumatic paddle sheets to achieve linkage, and finally a rotation shaft is driven to control swinging of settlement plates to make thestorage battery lower, thereby completing quick disassembly; and hanging boards can tow and suspend the storage battery to avoid falling directly to the ground, an overall disassembly step does not require the aid of peripheral tools, and the storage battery is guaranteed not to be bumped during a disassembly process, so that the service life is improved, and the safety is greater.

Description

technical field [0001] The invention relates to the field of pure electric vehicle batteries, in particular to a quick battery replacement device for pure electric vehicles using the principle of gas pressure linkage. Background technique [0002] With the advancement of science and technology, the new energy vehicles launched not only play a huge role in environmental protection compared with fuel vehicles, but also are more economical in terms of household use. When purchasing new energy vehicles, they can also enjoy the preferential policy of exemption from purchase tax. Energy vehicles have been greatly popularized. Initially, new energy vehicles had a long charging time in terms of battery life, so many manufacturers began to use battery replacement for battery life. Therefore, many types of battery replacement peripherals are popularized on the market. There are such problems in the use of existing battery replacement devices on the market: [0003] In the current te...
