Problems solved by technology

However, this can be problematic if the automation is installed out of the user's view, or if the procedure involves many steps
Also, when a wrong signal is generated, there will be a problem of needing to read the user manual to interpret the LED signal
Therefore, this method of signaling is inappropriate if it is an urgent procedure

Abstract

The invention relates to a electric gate-opening system, comprising a transmission device. The transmission device includes a driving pulley, an indirect pulley, a straining pulley and a transmission rope. The driving pulley, indirect pulley and the straining pulley are provided in a straight line at intervals, the indirect pulley is deposited between the driving pulley and the straining pulley, peripheral surface of the driving pulley is provided with at least one radially arranged first annular groove, peripheral surface of the indirect pulley is provided with a plurality of radially arranged second annular groove, peripheral surface of the straining pulley is provided with a third annular groove, the transmission rope encircles around the first annular groove, the second annular grooveand the third annular groove. One part of the transmission rope encircles around the first annular groove and the second annular groove in a spiral route, thus, the transmission rope can closely encircles around peripheral surface of the driving pulley, indirect pulley and the straining pulley, and there is no contact between each parts of the transmission rope, the indirect pulley and straining pulley can be driven by the driving pulley in turn.

Description

technical field [0001] The invention relates to a door opening system, in particular to an electric door opening system for a garage door. Background technique [0002] A garage door operator (GDO) generally includes components such as a motor, a transmission mechanism, a trolley, and a connecting arm for opening or closing a garage door. At present, the most common garage door opening system is to use a chain or a toothed belt meshed with gears as the transmission mechanism. Its main disadvantages are that the manufacturing process is complicated, expensive and requires many assembly steps. In addition, the garage door opening system using the chain as the transmission mechanism tends to generate noise during the process of opening or closing the door. Furthermore, due to the weight factor, a large horsepower must be provided to drive the chain drive system. [0003] Additionally, some of the latest garage door opening systems incorporate advanced automated learning feat...
