In order to when season in spring and autumn proper temperature, effectively be carried out using the mode of natural heat dissipation to power battery pack cold
But, to reduce vehicle energy consumption, course continuation mileage is lifted, it is necessary to the structure for being designed to quickly to move by thermal insulation board --- in cold
Winter and hot summer, allow thermal insulation board tightly to paste the surface of the case lid of battery case（Meanwhile, the bottom of casing and surrounding
The insulation material layer not moved is covered with the inwall of sidepiece）, start power battery thermal management system, electrokinetic cell carried out
Temperature control；When season in spring and autumn proper temperature, then thermal insulation board is removed, it is suspended on the surface of case lid, and keep
A certain distance, in favor of power battery pack natural heat dissipation, final reduction carries out the energy resource consumption of heat management to electrokinetic cell, and
And thermal insulation board conveniently moving is quick, occupies little space.
1st, elevating mechanism and its method for operation：
When thermal insulation board 2 rotates up rise, the top of upper hinge support 31 and middle connecting rod 32 relatively rotates, meanwhile, middle connecting rod
32 bottom relatively rotates with lower hinge support 33, and the top surface of thermal insulation board 2 and case lid 1 after rotation rise is separated, and hangs
Sky is in the surface of case lid 1.

When, thermal insulation board 2 is lowered, and in the presence of torsionspring 42, being pressed on the top surface of case lid 1 tightly of thermal insulation board 2.
3rd, position-limit mechanism and its method for operation：
When thermal insulation board 2 is raised or lowered to precalculated position, first passing through spacing pin cap 54 will pull out after spacer pin 52, after pull out it is same
When, limit spring 55 is compressed, then spacing hole 522 of the front end with being inserted into of the spacer pin 52 after being pulled out by after is aligned, then
Spacing pin cap 54 is unclamped, now, in the presence of the restoring force of limit spring 55, it is spacing that spacer pin 52 can insert that it is aligned
In hole 522, it is fixed with the link position to thermal insulation board 2, case lid 1.
