Mobile drive deivce

Abstract

The invention discloses a movable driving device which comprises a motor (2), a guide rail (1) and a hanging bracket (3), an roller wheel (4) and a movably power supply device, wherein the output end of the motor (2) is in driving connection with the roller wheel (4); the movably power supply device comprises a pedestal (5), an insulated sliding seat (6); two parallel conductive strips (9) and an insulated movable block (7) moving with the motor (2) together; a pair of conductive brushes (8) are arranged on the insulated movable block (7); the bottoms of the conductive brushes (8) are contacted with the surfaces of the two conductive strips (9) respectively. Compared with the prior art, the movable driving device has smoother translation motion and low working noise; through the movable power supply device, the motor on the move obtain continuous power supply so as to realize the technical proposal; the movable driving device is quite suitable for an automatic door; meanwhile, the movable driving device has a compact structure and more reliable performance and needs no transmission mechanism or a belt, thereby effectively reducing production cost.

Description

Technical field [0001] The invention relates to the technical field of automatic doors, in particular to a mobile driving device capable of driving automatic doors to open and close. Background technique [0002] The application of automatic doors in people's daily life has been very common, especially in public places such as hotels, shopping malls, banks, office buildings, and special occasions such as hospital operating rooms and sterile production workshops. The movable door leaves of automatic doors are driven by a mobile driving device to move it aside. This mobile driving device generally includes a guide rail, a motor fixed on one side of the guide rail, a transmission mechanism, and a hanger connected to the output end of the transmission mechanism. , Set on the hanger and roll along the guide rail, the hanger is connected to the top of the door leaf, so that the motor drives the roller to roll on the guide rail through the transmission mechanism, so that the hanger and ...

AI Technical Summary

Problems solved by technology

In the actual use of the belt-driven sliding door, the belt is prone to loosening. When the roller moves at high speed on the guide rail, it is easy to cause sticking, dragging, and jumping. Moreover, it is equipped with a mechanical transmission mechanism, and the processing and assembly accuracy requirements are relatively high. High, the production cost also increases thereupon, also can increase the amount of working noise simultaneously, and when the motor of the sliding door is in the state of power failure, it is difficult to open the door leaf, therefore, this kind of mobile driving device with the motor fixed relative to the guide rail needs to be further improved
