Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicle battery swap stations, and in particular relates to an AGV trolley for battery swap stations. Background Art

[0002] An AGV is an industrial vehicle that loads goods automatically or manually, travels automatically along a set route or tows a cargo trolley to a designated location, and then loads and unloads goods automatically or manually. It is often used in battery swap stations to replace vehicle batteries. The structure of an AGV usually includes a frame running on guide rails and a battery swap platform set on the frame. The battery swap platform serves as a temporary carrier for the battery.

[0003] At present, when battery swapping stations are performing battery swapping operations, they usually require a centering mechanism to align and correct the vehicle, and for the AGV to run under the vehicle battery to replace the battery. In order to ensure that the battery can be removed smoothly from the AGV, the centering mechanism needs to have an extremely high level of centering. Under this limitation, the centering mechanism often needs to be centered multiple times before it can complete the centering of the vehicle.

[0004] In the above technology, although the battery replacement of new energy vehicles can be completed, if there is no guarantee that the centering mechanism can make the vehicle fully meet the centering standard in a short time, the battery replacement efficiency will be reduced. During peak hours, it will affect the experience of waiting customers. Therefore, a solution is needed to enable the AGV car to quickly complete the battery replacement. Utility Model Content
