Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric vehicle battery swap, in particular to a rollover prevention device, a lifting machine and a battery swap station. BACKGROUND

[0002] With the development and popularization of new energy vehicles, battery pack fast swap technology has also developed rapidly. For large vehicles, such as heavy trucks or light trucks, the vehicle body and the load are very heavy, which leads to a higher demand for the capacity of the battery pack of the large vehicle. Therefore, a large-capacity electric energy is required to support the use of the large vehicle, or a convenient and reliable battery swap station needs to be provided for the new energy vehicle to meet the operation needs of the new energy vehicle.

[0003] A battery swap station usually has a vehicle loading platform capable of carrying a battery swap vehicle. In order to facilitate the execution of the battery swap operation, a pit or a lifting machine is usually arranged on the vehicle loading platform to lift the battery swap vehicle to ensure that the bottom of the vehicle has sufficient operation space. However, the pit occupies a lot of installation space and has a high safety risk. When the lifting machine is used to lift the battery swap vehicle, the wheels of the battery swap vehicle will first contact one side of the platform when driving in and out of the lifting device, which will cause the platform to shake and have a tendency to overturn relative to the base. Moreover, the shaking of the platform will also be transmitted to the lifting mechanism between the platform and the base, which will affect the stability of the connection structure between the lifting mechanism and the platform and / or the base, and ultimately affect the battery swap efficiency and the user's battery swap experience.

[0004] Therefore, the prior art has many drawbacks and needs to be further improved and enhanced. CONTENT OF THE UTILITY MODEL
