A ramp device for a temperature box

Abstract

The invention discloses a temperature tank slope rack device which comprises a base and a moveable plate, wherein an inclined surface is arranged on one side of the base; the moveable plate is arranged at the top of the base; a rotating shaft arranged in parallel to the moveable plate is arranged inside the base; a connecting piece for driving one end far away from the inclined surface, of the moveable plate, to incline is arranged on the rotating shaft; a locking pin for positioning an inclination angle of the moveable plate is arranged inside the base; a rotating base which can be automatically returned is arranged on the base; a sensing end which extends outside the inclined surface upwards is arranged in the middle of the rotating base; an action end for driving the connecting piece to rotate upwards is arranged on one side close to the top of the inclined surface, of the rotating base; and a release end for releasing positioning of the inclination angle of the moveable plate, of the locking pin is arranged on one side close to the bottom of the inclined surface, of the rotating base. The invention aims to provide the temperature tank slope rack device which can flexibly convert opening and closure states of a temperature tank.

Description

technical field [0001] The invention belongs to the field of electric vehicle battery detection, and in particular relates to a temperature box ramp device. Background technique [0002] With the development of domestic electric vehicles, more and more attention is paid to the testing of battery packs. The existing simulation environment generally uses a walk-in temperature box, and the inside of the walk-in temperature box has a certain height from the ground, and the door needs to be placed before the sample. After entering, it is completely closed with the box. For the heavy battery pack, it is more difficult to get in and out of the temperature box. Either use a lift forklift, or use a ramp frame with an ordinary forklift. The former has higher cost and space requirements. The latter slope frame, such as Chinese Patent Publication No.: CN203065921U, discloses a folding plate type road shoulder slope frame, which belongs to the technical field of road shoulder slope fram...

Problems solved by technology

However, for such a ramp frame, when the door of the temperature box is opened, the highest point of the ramp frame needs to be flush with the inner box of the temperature box. Since the lowest point of the door of the temperature box is lower than the bottom surface of the inner box of the temperature box, the door of the temperature box is closed when the temperature box is closed. It will interfere with the top of the ramp frame and the door cannot be closed. In order to close the door smoothly, the ramp frame needs to be moved, which increases the labor intensity of the staff, reduces the detection efficiency, and causes great inconvenience to the work.
