Self-propelled lifting device for battery replacement of electric vehicle

Abstract

The invention discloses a self-propelled lifting device for battery replacement of an electric vehicle, which comprises self-propelled lifting unit devices for synchronously lifting four wheels of the electric automobile, and is characterized in that each self-propelled lifting unit device comprises an AGV serving as a walking mechanism, a support frame and a lifting driving device. Two fork rods used for forking wheels are fixed to the front portion of the AGV, and the supporting frame is connected with the AGV through a lifting driving device and moves along with the AGV. The lifting driving device is connected with an automatic controller in the AGV and used for driving the AGV to ascend and descend relative to the supporting frame, and the supporting frame abuts against the ground to provide support for ascending and descending of the AGV. The electric vehicle lifting device can be put in places where electric vehicles need to be replaced anytime and anywhere, the vehicles are automatically lifted, using is flexible and convenient, bearing is stable and reliable, and the working efficiency is high.

Description

technical field [0001] The invention relates to a self-propelled lifting device for battery replacement of electric vehicles. Background technique [0002] With the popularization of electric vehicles, in order to solve the problem of oil-to-electricity conversion of electric vehicles, the current solution is to use the battery replacement mode. Some existing car companies have launched a variety of battery replacement models. The batteries of this type of battery replacement model are usually installed on the bottom frame of the vehicle. Carry out the operation, that is, raise the vehicle through the facility to suspend the bottom frame, and then send the mechanical arm or the operating trolley under the frame to load and unload the battery. [0003] Currently on the market for electric vehicle battery replacement stations, the internal facilities used for vehicle bottom operations are the same as the original facilities for ordinary vehicle repair and maintenance. They ar...

AI Technical Summary

Problems solved by technology

[0004] 1. It is too dependent on the site, occupies a large area, and is not flexible to use; since this type of trench or fixed lifting frame is a fixed facility on the ground, the supporting battery charging and storage and transportation facilities in the replacement station can only be integrated It is built and bound to each other, which requires a relatively open site, and is not suitable for construction in areas such as the city center with heavy traffic and land shortage, or narrow underground garages

[0005] 2. The known fixed lifting frame is often composed of a series of complex and precise mechanisms, which work together to complete a series of actions such as alignment, locking and lifting for electric vehicles. The overall structure is complex. It is difficult to disassemble and transfer, and requires professionals to install and debug, which is expensive and equipment maintenance costs are high

Moreover, a set of institutions only serves a single type of electric vehicle, and the scope of application is very limited. In addition, some car companies have invested heavily in self-contained power stations, which cannot achieve high-density layout.

[0006] 3. The interior of the existing battery swap station usually only corresponds to one type of car, so there is no wheelbase and wheelbase problems when lifting and aligning. If it is to meet the needs of battery swapping for all vehicles, a complex mechanical structure must be added to the lifting device. Adapt to the wheelbase and wheelbase, even if it still puts forward quite high driving technical requirements for the driver to park in a precise fixed position

However, this lifting device is limited to the lifting and moving of the vehicle, and cannot be used as battery replacement or bottom maintenance of electric vehicles, and has the following disadvantages:

[0010] 3. Due to the need to carry and balance the forces in all directions at the bottom of the vehicle, the AGV trolley must also be equipped with a supporting balance and stabilization mechanism to provide a stable supporting force, resulting in a complex overall structure of the lifting device, inconvenient operation, and relatively low manufacturing and maintenance costs. higher

[0011] Therefore, there is no precedent for the application of AGV trolley as a vehicle lifting tool in the field of electric vehicle battery replacement.
