Title:
EXPLOSION-PROOF VALVE PLUGGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/060678
Kind Code:
A1
Abstract:
The present application relates to the technical field of battery pack testing devices, and provides an explosion-proof valve plugging apparatus. The explosion-proof valve plugging device comprises a seal cover, a magnetic member and a first driving member. The seal cover is used for covering the end of the explosion-proof valve provided with a valve cover. The magnetic member is arranged in the seal cover, and the magnetic member is used for attracting the valve cover. The first driving member is transmittingly connected to the magnetic member and is used for driving the magnetic member to move relative to the seal cover, so that the magnetic member contacts the valve cover and drives the valve cover to be opened. After the explosion-proof valve is plugged by the explosion-proof valve plugging device, the first driving member first drives the magnetic member to contact and attract the valve cover, and then drives the magnetic member to drive the valve cover to be opened. The magnetic member has a certain stroke, so that the valve cover is pulled up high enough, and the risk of low inflation efficiency of the explosion-proof valve plugging device on a battery pack due to small inflation flow is reduced.
