The invention discloses a lifting and lowering device for power battery frames of an electric vehicle (EV). The lifting and lowering device comprises an upper frame and a lower frame mounted at a chassis of the EV, wherein the lower frame is provided with battery mounting frames; openings for inserting power batteries are arranged at the outer ends of the battery mounting frames; the sides of theupper frame are provided with first fixing plates and second fixing plates arranged in parallel; rotating shafts are arranged between the first fixing plates and the second fixing plates; the rotatingshafts are rotationally connected with L-shaped folding plates; the front and rear sides of the lower frame are provided with connecting plates; the connecting plates are provided with obround holes;sliding blocks are arranged in the obround holes; position-limiting columns are arranged at both ends of each sliding block; linear motors are horizontally arranged at the front and rear sides of theupper frame; driving shafts of the linear motors are perpendicular to axes of the rotating shafts; and one end of each folding plate is rotationally connected with the corresponding position-limitingcolumns and the other end of the each folding plate is hinged with the driving shaft of the corresponding linear motor. The lifting and lowering device for the power battery frames of the EV can realize the lifting and lowering of the lower frame in the narrow space at the bottom of the EV so as to ensure the mounting and dismounting of the power batteries.
Description
technical field [0001] The invention relates to the field of electric vehicles, and more specifically relates to a lifting device for a power battery frame of an electric vehicle. Background technique [0002] At present, the two power batteries on the electric vehicle on the market are installed on the chassis of the electric vehicle, and are symmetrically arranged on both sides of the electric vehicle. When the power battery needs to be replaced, the installation frame on both sides of the power battery rotates, thereby The power battery can be disassembled and installed, but this quick change method needs to be improved in order to facilitate the removal and replacement of the power battery, which leads to a higher chassis of the electric vehicle. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a lifting device for a power battery frame of an electric vehicle that can be lifted and lowered in a narrow space,...
