The whole electric automobile can be lifted by using a single lifting device 3, and the lifting and resetting can also be realized by using a plurality of lifting devices 3, and the lifting and resetting are realized by using two lifting devices 3 as an example.
The support 2 can be mobile, in particular can be mobile in the direction of the preset path, or in the direction perpendicular to the preset path, or in both directions.
Support piece 2 can realize the location to the wheel, thereby can accurate definite electric automobile's position when trading the electricity at every turn, the position scope of the battery package of treating the change has correspondingly been confirmed, and then be favorable to improving the automation of trading the electricity process, and simultaneously, because support piece 2 is portable, when needs trade the electricity to different electric automobile, can corresponding adjustment support piece 2's position, have the electric automobile of different wheel bases and wheel bases with the adaptation, thereby make and carry the electric automobile that car platform 10 can be to multiple model and fix a position, consequently, single electric automobile that trades station 100 can adapt to multiple model, higher flexibility has, the construction cost who trades station 100 has been reduced, the cost of trading has generally been reduced.
For example, when the electric vehicle needing to be replaced has a larger wheel base, the support 2 may be moved along the direction of the preset path to increase the distance between the two supports 2 in the direction of the preset path. And vice versa.
For another example, when the electric vehicle needing to be replaced has a larger wheel track, the support 2 may be moved in a direction perpendicular to the preset path to increase the distance between the two supports 2 in the direction perpendicular to the preset path. And vice versa.
As shown in fig. 7, 8 and 9, the supporting member 2 includes a limiting member 21 (i.e., corresponding to the first limiting member and the second limiting member), and the limiting member 21 is used for limiting the movement trend of the wheel in the front-rear direction and/or the movement trend in the left-right direction.
