A vehicle-carrying platform and its vehicle wheelbase detection device and method

Abstract

The invention discloses a vehicle carrying platform and a vehicle wheelbase detection device and method thereof. The vehicle carrying platform is arranged in a fully-automatic storage garage. The vehicle wheelbase detection device comprises a plurality of weighing platforms, which are arranged on the vehicle carrying platform and corresponding to vehicle wheel positions of vehicles to be stored, wherein the upper surface of each weighing platform is flushed with the upper surface of the vehicle carrying platform; a plurality of weighing sensors, which are arranged on the bottom surfaces of the weighing platforms respectively, and are used for collecting weight information of the vehicles to be stored, and converting the weight information into analog electrical signals which are then amplified and output; and a data acquisition and processing system, which is connected with the plurality of weighing sensors, and is used for receiving the analog electrical signals, calculating vehicle wheel strength center point position of each vehicle to be stored by utilizing a torque balance principle, and calculating vehicle wheelbase of each vehicle to be stored according to each vehicle wheel strength center point position. The invention also discloses a vehicle wheelbase detection method.

Description

technical field [0001] The invention relates to a vehicle storage device and method for a fully automatic storage garage, in particular to a vehicle wheelbase detection device and method that can improve the overall efficiency of car storage and retrieval in the garage. Background technique [0002] In the current various forms of automated three-dimensional storage garages, there is a lack of equipment or devices for vehicle wheelbase detection, and the vehicle is forced to be transported only by the adaptability of the carrier. The core is to realize the contact between the carrier mechanism and the vehicle tires. The automatic handling of vehicles in the garage, however, the transporter mechanism itself has structural limitations, coupled with the variety of vehicle shapes and new ones, in the case of unknown wheelbase, it is very easy to cause damage to the vehicle during the handling process, especially For grippers. [0003] For a specific vehicle, its wheelbase size ...

AI Technical Summary

Problems solved by technology

[0004] 1) Limited by the size of the detection switch body and the size of the installation space on the push rod, it is often not possible to arrange many, resulting in a large range of wheelbase measurements that are not accurate enough, resulting in the risk of damage to the vehicle that the carrier still has;

[0005] 2) The push rod directly pushes the side of the wheel, which will cause slight damage to the wheel surface and cause discomfort to the owner

[0006] Therefore, it is essential to automatically detect the wheelbase size of the vehicle. If the wheelbase of the vehicle is too large or too small, the carrier cannot effectively move the vehicle, and at the same time it will damage the vehicle.
