Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as Figure 1 to Figure 11 The invisible protective net shown includes a retraction control system, guide rails 10 and a net curtain assembly 20, and the net curtain assembly 20 includes a reel shaft 30, a power shaft 40 and a net curtain body wound on the reel shaft 30 50, the net curtain body 50 has two opposite ends 501, one end 501 is fixed on the reel shaft 30, and the other end is inserted into the guide rail 10 after bypassing the power shaft 40, in this embodiment, One end of the net curtain body 50 fixed to the reel shaft 30 is a fixed end, and one end of the net curtain body 50 inserted into the guide rail 10 is a free end. The free end of is always defined in the guide rail 10;
[0028] A toggle mechanism is provided between the power shaft 40 and the net curtain body 50 to drive the net curtain body 50 to unwi...

The invention relates to an invisible protective screen which is mounted on places of doors, windows, ventilation openings, balconies and the like, in particular to a folding and unfolding control system of the invisible protective screen. The folding and unfolding control system comprises a driving motor and a controller which is connected with the driving motor so as to control the driving motorto rotate. The folding and unfolding control system further comprises an angle displacement measuring device which is used for directly or indirectly measuring the angle displacement of an output shaft of the driving motor. The angle displacement measuring device is connected with the controller so that the controller can acquire the measured data of the angle displacement measuring device. The other objective of the invention is to provide the invisible protective screen which adopts the folding and unfolding control system. According to the folding and unfolding control system and the invisible protective screen which adopts the folding and unfolding control system, by arranging the controller and the angle displacement measuring device, the angle displacement of the output shaft of thedriving motor can be detected in real time, thus the opening degree of the invisible protective screen can be known, and control over and setting of the opening degree of the invisible protective screen can be achieved conveniently.
Description
technical field [0001] The invention relates to an invisible protective net installed in doorways, windows, air vents, balconies and other places, in particular to a retraction control system of the invisible protective net. Background technique [0002] In the prior art, invisible protective nets installed on doorways, windows, vents, balconies, etc. can minimize the impact of people looking out to the outside world on the basis of anti-theft and anti-fall. And the invisible protective net is further improved by adopting the technology of rolling and unfolding. When it needs to be used, unfold the net curtain body, and when not in use, roll up the net curtain body to improve the user experience. But the unfolding operation of the existing invisible protective net is relatively difficult, and there is no selection or setting of the degree of opening. Contents of the invention [0003] The main purpose of the present invention is to provide a retraction control system for...
