Vertical butt joint type vehicle end liquid cooling connecting device, battery mounting part and electric vehicle

Abstract

The invention discloses a vertical butt joint type vehicle end liquid cooling connecting device, a battery mounting part and an electric vehicle, and the liquid cooling connecting device comprises a mounting seat which is arranged in a containing cavity at the bottom of the electric vehicle; the connecting valve is fixed on the mounting seat, one end of the connecting valve is connected with a cooling liquid supply device, the other end of the connecting valve is used for being connected with a battery pack, a circulation channel capable of being opened and closed is formed in the connecting valve, and the circulation direction of the circulation channel is perpendicular to the direction of a plane where the length direction of a vehicle body of the electric vehicle is located; the battery pack can be communicated with a liquid cooling pipeline of the electric automobile after being installed on the electric automobile from bottom to top. According to the scheme, in the process of installing the battery pack to the bottom of the electric automobile, the battery pack is lifted from bottom to top, when the battery pack is lifted upwards in place, communication between a connecting valve of the electric automobile and a liquid cooling connector of the battery pack can be achieved while the battery pack is installed, sealing performance is ensured, liquid leakage is prevented, and the installing and connecting process is simple and efficient.

Description

[0001] This application claims the priority of Chinese patent application 202010981928.8 with a filing date of 2020 / 09 / 17. This application cites the above patent application in its entirety. technical field [0002] The invention relates to the field of battery replacement for electric vehicles, in particular to a vertical butt joint vehicle end liquid cooling connection device, a battery installation part and an electric vehicle. Background technique [0003] At present, there are mainly two ways to obtain energy for electric vehicles: charging and battery replacement. Because the power swap method can realize rapid power supply, reduce the waiting time of customers, and improve the utilization rate of the swap station. In addition, the battery can be charged intensively at night, realizing the "peak-shaving energy storage" of the electric load. At the same time, it improves the comprehensive utilization efficiency of electric equipment and prolongs the service life of b...

Problems solved by technology

However, the current quick-change battery pack and the plug-in connector structure on the quick-change bracket assembly are not perfect in liquid tightness due to the limitation of the locking position of the locking mechanism of the battery pack, and there may be a problem of dripping, which will cause leakage other security risks

Therefore, the design of the liquid cooling connector on the replaceable battery pack is greatly restricted
