Protection device for new energy automobile battery

Abstract

The invention relates to the technical field of strategic emerging industries, and discloses a protection device for a new energy automobile battery, the protection device comprises a base, four springs are fixedly mounted at four corners of the top end of the base, a pressure sensing plate is fixedly mounted at the top ends of the four springs, and a lower air bag is fixedly mounted at the top end of the pressure sensing plate. Downward air flow is generated through the upper air bag, downward pressure is applied to the top pressing plate by the air flow, upward pressure generated by vibration is effectively counteracted, accordingly, vibration collision of the battery pack is avoided, the bottom end of the battery pack is prevented from being deformed and damaged, a negative pressure cavity is formed in one end of the power transmission end through the air flow flowing in the flow transmission pipe, the plug inserted into the inner cavity of the power transmission end is stabilized in the inner cavity of the power transmission end, the phenomenon that the plug falls off is avoided, normal transmission of a circuit is guaranteed, airflow flows in the inner cavity of the upper air bag, the heat dissipation effect of the bottom end of the battery pack is achieved, and insufficient power of a new energy automobile caused by overheat of the battery pack is avoided.

Description

technical field [0001] The invention relates to the technical field of strategic emerging industries, in particular to a protective device for new energy vehicle batteries. Background technique [0002] Strategic emerging industries are the main development direction of modern industry development, and the new energy industry included in it has excellent prospects. For the products included in the new energy industry, new energy vehicles are new products that have been focused on development in recent years A new energy vehicle is a vehicle that uses unconventional vehicle fuel as a power source, or uses a new technology and a new structure of a new vehicle power unit. The existing new energy vehicles are mainly divided into four types, hybrid electric vehicles, Pure electric vehicles, fuel cell electric vehicles, and supercapacitor vehicles, no matter what type they are, the main power source used by new energy vehicles is batteries, and the batteries of new energy vehicles...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of existing new energy vehicle batteries proposed in the background technology, the present invention provides a protective device for new energy vehicle batteries, which is equipped with a protective battery pack to prevent the battery pack from being damaged when the vehicle body vibrates up and down. Collision damage occurs, the advantages of effectively absorbing the wiring port and avoiding the wiring falling off solve the technical problems raised in the above-mentioned background technology
