Embodiment 1

[0058] like Figures 1 to 3 As shown, Embodiment 1 discloses a liquid cooling connection assembly 5000, the liquid cooling connection assembly 5000 is used between the liquid supply device and the liquid cooling pipeline, and the liquid cooling connection assembly 5000 realizes the connection between the liquid supply device and the liquid cooling pipeline. The communication between the liquid cooling pipelines allows the cooling liquid in the liquid supply device to flow into the liquid cooling pipelines and return to the liquid supply device, thereby realizing heat exchange in the area where the liquid cooling pipelines are set.

[0059] Specifically, the liquid cooling connection assembly 5000 includes a first liquid cooling connection device 5100 and a second liquid cooling connection device 5200, the first liquid cooling connection device 5100 is used in conjunction with the second liquid cooling connection device 5200, and one of them is provided as The connecting joint ...

Embodiment 2

[0080] like Figure 4 As shown, Embodiment 2 discloses a battery pack 6000, which is used in an electric vehicle to provide power for the electric vehicle. And the battery pack 6000 has the first liquid cooling connection device 5100 or the second liquid cooling connection device 5200 with the structure in the above-mentioned embodiment 1, and the first liquid cooling connection device 5100 or the second liquid cooling connection device 5200 is used as the battery terminal liquid cooling device. The connecting device is provided on the battery pack 6000 . In the battery terminal liquid cooling connection device, the first installation seat 5110 and the second installation seat 5210 as well as the first connection valve 5120 and the second connection valve 5220 are collectively referred to as the installation seat and the connection valve.

[0081] When the battery pack 6000 is installed on the electric vehicle, the liquid cooling connection device at the battery end communica...

Embodiment 3

[0092] like Figure 5 As shown, Embodiment 3 discloses another battery pack 6000. The difference between this battery pack 6000 and the battery pack 6000 in Embodiment 2 is that the installation position of the liquid cooling connection device at the battery end is different, and the other structures and functions are completely the same. The same structure and function will not be repeated.

[0093] The battery terminal liquid cooling connection device on the battery pack 6000 of the third embodiment, the mounting seat is also arranged on the top surface or side of the battery pack 6000, but the plane direction of the mounting seat is perpendicular to the plane direction of the battery pack 6000 , and the plane direction of the mounting seat is perpendicular to the flow direction, that is to say, the flow direction of the circulation channel is parallel to the plane direction of the battery pack 6000, so that the battery pack 6000 is installed in the electric vehicle in a hor...

Abstract

The invention discloses a liquid cooling connecting device with a floating function, a battery pack and an electric automobile, and the liquid cooling connecting device comprises a mounting seat which is arranged in a containing cavity at the bottom of the electric automobile or on the battery pack; the connecting valve is fixed on the mounting seat, one end of the connecting valve is connected with the liquid supply device, and the other end of the connecting valve is used for being connected with a liquid cooling pipeline; the mounting base comprises a mounting plate fixed to the battery pack or in a containing cavity in the bottom of the electric vehicle and a moving mechanism capable of stretching and moving in the circulation direction of the circulation channel relative to the mounting plate, and the connecting valve is fixedly arranged on the moving mechanism. According to the liquid cooling connection device, the movement amount of the connection valve is increased, the connection valve moves more stably, the connection stability of the connection valve is guaranteed, the leakage phenomenon of cooling liquid is effectively avoided, and the installation stability of the liquid cooling connection device is greatly improved. And the problem of unstable connection of the connecting valve caused by factors such as vehicle vibration and the like is solved in a follow-up mode of the connecting valve.

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 a liquid cooling connection device with a floating function, a battery pack and an electric vehicle. Background technique [0003] There are two main 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 batteries, which has high promotional value and economic significance. [0004] In a battery-swappable elec...
