AI Technical Summary

Technical Problem

When the power is lost, the air inlet cannot open automatically, preventing the internal gas from exchanging with the outside, which can lead to safety hazards such as temperature runaway and accumulation of harmful gases.

Method used

An air intake device was designed, comprising a rotating door panel, a drive unit, and a spring-loaded mechanism. The rotating door panel is driven by an explosion-proof motor to close when energized and to open automatically when energized. The automatic control of the air intake is achieved by the cooperation of the drive shaft and the spring-loaded mechanism.

Benefits of technology

When the power is lost from the energy storage box, the rotating door automatically opens to ensure internal gas exchange, prevent temperature runaway and accumulation of harmful gases, and improve safety and sealing performance.

Abstract

The application relates to the ventilation technical field of an electric energy storage box, in particular to an air inlet device applied to the electric energy storage box. The device comprises a containing shell, a rotating door plate and a driving device, the containing shell is provided with an air inlet opening, the rotating door plate can cover the air inlet opening, the driving device is located on one side of the air inlet opening and is fixed to the top of the rotating door plate, can provide a driving force to make the rotating door plate close when power is on, and can only provide an elastic restoring force to make the rotating door plate open when power is off. Through the above design, the air inlet device can be automatically opened for ventilation under the power-off state.
