The invention relates to an electric railless four-leaf folding door. Both sides of the electric folding door are respectively provided with an outer side door and an inner side door. The inner side door is fixed on a strut through a first hinge. The outer side door is connected with the inner side door through a second hinge. The electric folding door also comprises a folding mechanism and a door closing motor for realizing the telescopic action. One end of the door closing motor is fixed on the strut and the other end of the door closing motor is connected onto the inner side door. The folding mechanism is formed by a first rod piece, a second rod piece, a third rod piece and a fourth rod piece. One end of the first rod piece is hinged on the strut. The other end of the first rod piece is hinged with one end of the second rod piece. The other end of the second rod piece is hinged with one end of the third rod piece. The other end of the third rod piece is hinged with one end of the fourth rod piece. The other end of the fourth rod piece is hinged on the outer side door. Not only are both ends of the third rod piece respectively hinged with the second rod piece and the fourth rod piece, but also the middle of the third rod piece is hinged on the inner side door. The electric railless four-leaf folding door is of a railless structure, has a simple structure and is convenient to assemble and maintain.
Description
technical field [0001] The invention relates to the field of folding doors, in particular to an electric trackless folding door. Background technique [0002] In modern villas, gardens, factories and other occasions, the use cases of four folding doors can be seen everywhere. Compared with the traditional two-fold folding gate, the four-fold folding gate doubles the opening and closing space range of the gate, but relatively reduces the expansion space required after the gate is opened. However, modern life puts forward automation requirements for the opening and closing of the gate, and the uncertainty of the movement trajectory of the double doors in the four-fold folding gate puts forward higher requirements for the motorization of the four-fold folding gate. Among the existing patents, the retrieved patent number is "200820093554.0", and the name is "slide guide electric folding door". The special slideway can effectively solve the technical problem of the folding door...
