Locking device for battery box and body connection structure of battery box

Abstract

The invention discloses a battery case locking device and a vehicle body connection structure of the battery case, comprising a telescopic sleeve, a telescopic pin arranged in the telescopic sleeve and a telescopic sleeve that can be inserted into the telescopic sleeve, and a telescopic pin that is matched with the telescopic pin and fixed in the telescopic sleeve. The fixed sleeve, the telescopic sleeve is provided with a pressing rod that can drive the telescopic pin to move axially into the fixed sleeve, and the telescopic sleeve is provided with a column component that can keep the telescopic pin at the matching position with the fixed sleeve. A resetting part that enables the telescopic pin to exit the fixed sleeve is connected between the sleeves. The structure of the locking device is simple and reliable, and it is easy to process. The connection between the battery box and the body is easy to operate. The locking and unlocking actions can be realized only by pressing the telescopic mechanism, and the accuracy of the pressing and positioning of the battery replacement equipment is not high. While meeting the requirements for quick installation of the battery box and the vehicle body, it also ensures the reliability of the connection structure between the battery box and the vehicle body, shortens the battery box quick-change time, and improves the battery box quick-change quality.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a locking device for a battery box and a vehicle body connection structure for the battery box.
