Chassis battery change system for electric passenger cars and method of the system

Abstract

The invention discloses a chassis battery change system for electric passenger cars. The chassis battery change system comprises a rapid change robot, a battery change platform, a transfer platform, a background monitoring system, a stacking machine and a charging frame, wherein the transfer platform, the stacking machine and the charging frame are arranged on one side of the battery change platform; the rapid change robot is arranged between the battery change platform and the transfer platform; an electric passenger car is capable of passing through the battery change platform; a locking mechanism which corresponds to a battery box supported by the rapid change robot is arranged on the electric passenger car; and the background monitoring system is connected with the rapid change robot and the stacking machine respectively through an industrial Ethernet. At the same time, the invention also discloses a using method of the system. A mechanical positioning mechanism of the battery change platform is simple, correct in positioning and low in manufacturing cost; a hydraulic lifting mechanism is used in the rapid change robot, so that the whole change process is reliable and stable, the size of the change equipment is decreased effectively and the actual occupied area of the change system is saved; and the transfer platform is used as a battery change interaction link between the rapid change robot and the stacking machine, so that the time spent by the battery change is further shortened.

Description

technical field [0001] The patent of the present invention relates to a battery pack replacement robot for the chassis of an electric vehicle, in particular to a battery replacement system and method for an electric passenger vehicle chassis that automatically picks and places the battery of an electric passenger vehicle. Background technique [0002] As a new type of transportation, electric vehicles have the advantages of "zero emission" and wide energy sources. They are an important means to alleviate the shortage of oil resources and serious urban air pollution problems in my country. Valid carrier. However, the lag of battery technology and charging technology has become a bottleneck restricting the development of the electric vehicle industry. Governments and enterprises of various countries have made great efforts to improve the supporting basic service industry for electric vehicles. At present, there are two main modes of energy supply for electric vehicles: chargin...

Problems solved by technology

[0003] The invention patent of China State Intellectual Property Office with the patent application number CN201110042565.2 discloses a power battery quick-change system for electric passenger vehicles. Using the transmission device for the transmission and distribution of the power battery, on the one hand, the transmission and distribution of the battery will consume a lot of time, on the other hand, due to the large volume and quality of the battery, the risk of sideslip is prone to occur during the transmission process

The invention patent with the patent application number CN201010297770.9 discloses a battery replacement device and a battery replacement system for electric passenger cars. The battery replacement device of this system is a multi-axis rotary industrial robot, and its equipment occupies a large area. Larger, resulting in a larger output support torque of the manipulator

At the same time, there is no battery locking mechanism in the replacement device. During the overall rotation of the device, the battery is prone to slipping, which will affect the normal service life of the battery.
