Problems solved by technology
Existing electric vehicles have the following problems: ① In the past, electric vehicles used a jack-type lifting mechanism to realize the lifting of the battery compartment frame. The jack-type lifting mechanism needs to be replaced every two or three months, which is costly and troublesome; ②The lifting and lowering of the battery compartment frame is not synchronized, that is, the battery compartment frame is prone to tilting forward and backward, which is not convenient for the battery ③The battery compartment frame does not have a safe and reliable locking mechanism, which is prone to misuse, so that the battery compartment frame can rise or fall, causing potential safety hazards when the electric vehicle is driving; ④The battery needs a side limit device, otherwise It is easy to come out from the frame of the battery compartment, and the existing side limit devices are mostly manually operated, which is troublesome to operate

The invention discloses a vehicle body platform with a matched lifting quick-changing battery mechanism. The vehicle body platform with the matched lifting quick-changing battery mechanism is characterized in that a battery compartment used for accommodating a battery is fixed to the lower side of the vehicle body platform; the battery compartment comprises a frame body, and a plurality of lifting mechanisms are fixed on the frame body; each lifting mechanism comprises a power source which serves as a hydraulic power part and a hydraulic cylinder which serves as a hydraulic executing part, and a telescopic rod of the hydraulic cylinder is vertically arranged; a hydraulic cylinder body is fixed to the vehicle body platform, and the telescopic rod is fixed to the frame body; and under the action of the power source, the telescopic rod of the hydraulic cylinder is retracted and stretched to lift the frame body. The vehicle body platform with the matched lifting quick-changing battery mechanism has the advantages that the service life of the lifting mechanisms is longer, quick-changing for the battery is convenient, safety is higher, operation is convenient, and the travelling journey of an electric automobile is longer.
Description
technical field [0001] The invention relates to the field of pure electric vehicles, in particular to a body platform with a matching lifting and quick-changing battery mechanism. Background technique [0002] With the increasingly prominent energy and environmental issues in recent years, gasoline and diesel-powered vehicles have been subject to certain restrictions and impacts; while electric vehicles just meet the dual requirements of energy and environmental protection, which makes environmentally friendly and energy-saving electric vehicles become the automotive industry. an important branch. As the most promising alternative to fuel-powered vehicles, electric vehicles have become the focus of industry research and development. [0003] In the prior art, in order to facilitate the insertion or removal of the battery and to reduce the height of the center of gravity of the vehicle, the battery compartment is fixed on the lower side of the vehicle body platform, and the ...
