Problems solved by technology
[0004] Now many cars that support battery replacement, the battery replacement method is chassis battery replacement, and for each model, the distance between the front wheel and the rear wheel is not the same, and the parameters between models are also different, so it is necessary. A battery swap platform that meets the battery swap requirements of multiple models

Embodiment
[0028] Due to the different parameters of different models, it is necessary to do a good job of positioning in the Y direction of the electric vehicle (the Y direction is the vertical direction of the forward direction of the vehicle), that is, to do a good job of positioning on the different wheelbases of different models, so it is necessary to develop an electric vehicle replacement The Y-direction positioning device of the electrical platform. As shown in the present invention, there are four groups, which are placed parallel to the central axis of the power exchange platform and connected to the front wheels and rear wheels respectively. The structure of each group of devices is as follows Figure 1-4 As shown, it includes: a scissors mechanism 1 arranged crosswise, a left side baffle 31 and a right side baffle 32 connected to both sides of the scissors mechanism 1, wherein the right side baffle 32 is connected to the wheel, and is connected to the scissors mechanism. The ...

The invention relates to four Y-direction positioning devices for a power exchanging platform of electric vehicles. The four Y-direction positioning devices are parallel to the central axis of the power exchanging platform and connected with front wheels and rear wheels respectively; each device comprises a crossed scissor mechanism, baffles connected to the two sides of the scissor mechanism anda hydraulic power mechanism connected to the scissor mechanism, wherein the baffle at one side is connected with the corresponding wheel, and the hydraulic power mechanism drives the scissor mechanismto move so that the corresponding vehicle can move to the center. Compared with the prior art, the four Y-direction positioning devices have the advantages that current power exchanging equipment cannot be adjusted according to the front wheel distance and the rear wheel distance of different vehicles, and the power exchanging platform can be applied to vehicle models with different parameters.
Description
technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a Y-direction positioning device for a battery exchange platform of an electric vehicle. Background technique [0002] With the deteriorating global environment and the emergence of energy shortages, the advent of electric vehicles will solve this problem well. However, the power battery life of electric vehicles is a restrictive issue for the development of electric vehicles. [0003] At present, the waiting time for charging electric vehicles is long, so the operation mode of battery swapping for electric vehicles has emerged, which can greatly shorten the waiting time for users, which is almost the same as the time spent refueling fuel vehicles. [0004] Now many cars that support battery replacement, the battery replacement method is chassis battery replacement, and for each model, the distance between the front wheel and the rear wheel is not the same, and the p...
