This lifting rack structure is simple and facilitates the formation of the connecting portion on the lifting rack. The connecting portion is formed by the two connecting plates, thereby facilitating the stable connection between the connecting portion and the mounting portion.

[0010] Further, a fixing body is fixedly connected to the mounting portion at a position corresponding to the connecting portion. The two connecting plates on each connecting portion are fixedly connected to the opposite two side faces of one fixing body. The fixing body is generally fixedly connected to the mounting portion by means of a fixing bolt. The arrangement of the fixing body facilitates the fixation of the lifting rack. The position of the lifting rack on the mounting portion is stable.

[0011] Further, the front ends of the two mounting portions are bent and deformed to be fixedly connected to the opposite two sides of a vertical pipe. The lower end of the vertical pipe extends downward. The mounting rack is fixedly connected to the lower end of the vertical pipe. The upper end of the vertical pipe is connected to a faucet pipe.

Through the arrangement of the fixing rod, a larger connecting position can be provided, and relatively effective and stable connecting support can be provided for the mounting frame.

[0013] Further, the mounting frame comprises a bottom plate, the bottom plate constitutes the bottom of the mounting frame, and the bottom plate is connected to the mounting parts through a plurality of connecting pieces; and the front end of the bottom plate is fixedly connected to the outer circumferential surface of the fixing rod through bending deformation. Such a mounting frame can well adapt to the fixation with the fixing rod, the bottom plate has strong load bearing capacity, and can well adapt to the load bearing installation of the storage battery.

[0014] Compared with the prior art, the utility model has the beneficial effects that: the lifting frames can be arranged on the mounting parts to increase the depth of the mounting cavities, so that the installation of large-height storage batteries can be adapted to; and after the lifting frames are removed, the installation of small-height storage batteries can be adapted to. Through the arrangement of the lifting frames of different heights, the installation of storage batteries of different heights can be adapted to, so that the electric vehicle can be adapted to the installation of storage batteries of various specifications without increasing the transverse size, the actual use requirement is well met, and the replacement of the on-vehicle storage battery of the take-out electric vehicle is facilitated. After the lifting frames are mounted on the electric vehicle, the upper end faces of the two lifting frames are flush, the arrangement of the lifting frames will not hinder the arrangement of the pedal, and the basic normal use requirement of the electric vehicle can be met.
