Sliding door

Abstract

The invention relates to a sliding door. The sliding door comprises a fixed plate, a door plate, an upper sliding swing arm assembly, a lower sliding swing arm assembly, a motor, a first connecting rod, a second connecting rod, a third connecting rod and a first shaft. A power component of the sliding door is the motor, the third connecting rod can be pushed to move through the first connecting rod and the second connecting rod, the third connecting rod can drive L-shaped arms in the upper sliding swing arm assembly and the lower sliding swing arm assembly to synchronously rotate, the L-shapedarms drive the swing arms to move, the middles of the swing arms can only rotate around a fourth shaft, and one end of each swing arm is hinged to a sliding block through a second shaft, and then canonly move in a straight line; and the situation that L1 is equal to L2 and L3 is defined, the structures are mutually compensated, the other end of each swing arm can only do translational motion toform a large cantilever structure, consequently, the swing of the swing arms is converted into translational motion, the structure design is ingenious without excessive sliding rail guiding, large stroke can be output, stress is large, and the volume is small.

Description

technical field [0001] The invention relates to the technical field of mechanical mechanisms, in particular to a translation door. Background technique [0002] Sliding doors are used in many fields, such as passage gate sliding doors. The existing sliding doors must first meet the requirements of sufficient travel, resulting in more complex structures, larger volumes, and less force, which cannot meet the requirements of higher and higher standards. Technical requirements need to be improved. Contents of the invention [0003] The object of the present invention is to provide a translational door with large stroke, large force and small volume. [0004] The technical solution provided by the present invention is: a translation door, including a fixed plate, a door panel, an upper translation swing arm assembly, a lower translation swing arm assembly, a motor, a first connecting rod, a second connecting rod, a third connecting rod and a first shaft, the motor is fixed on...
