Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 4, the sunshade curtain detecting device of the present invention includes a frame 10, a sunshade curtain fixing mechanism 20 provided on the frame 10, a driving mechanism driving the retraction of the sunshade curtain, a first detecting mechanism 30 detecting the torque of torsion springs of the sunshade curtain during the retraction of the sunshade curtain, and/or a second detecting mechanism detecting the sagging amount of the curtain of the sunshade curtain.
Specifically, the sunshade curtain fixing mechanism 20 includes a plurality of side-by-side fixing seats 21 disposed on two opposite sides of the frame 10, and a curtain guide rail 22 disposed on each fixing seat 21 along the folding and unfolding direction of the sunshade curtain, wherein two opposite fixing seats 21 near the end of the frame 10 are provided with reel insertion holes 23, and the reel insertion holes 23 on the two fixing seats 21 are disposed oppositely; the two curtain guide rails 22 are provided with clamping grooves 24 for clamping the curtain sides of the sun-shading curtain. The two ends of the roller of the sunshade curtain are respectively clamped in the two roller insertion holes 23, the two sides of the curtain are clamped in the two clamping grooves 24, and the curtain is stably guided to be retracted and released by the two clamping grooves 24, so that the detection precision can be ensured.
Of course, in order to accommodate reels of different thicknesses, a plurality of reel insertion holes 23 of different sizes may be provided on the fixing base 21 as required.
In addition, the invention is provided with two compression bar supports 25 which are respectively close to two fixing seats 21 provided with scroll insertion holes 23 on the end part of the frame 10, and a clamping block 26 for fixing the end part of the compression bar is arranged on the compression bar supports 25. The two clamping blocks 26 are provided with the pressing rods, so that curtain cloth released from the winding shaft can be pressed to the horizontal height of the clamping groove 24, and the detected torque of the torsion spring and the detected sagging amount of the curtain cloth are ensured to be reliable and accurate.
Of course, in order to smoothly transition the curtain cloth released from the reel into the clamping groove 24, the curtain cloth guide blocks 27 are arranged on the two fixing seats 21 provided with the reel insertion holes 23, and the curtain cloth guide blocks 27 are close to the entrance of the curtain cloth guide rail 22.
In order to enable the sunshade curtain to be automatically and stably retracted, the driving mechanism of the invention comprises two synchronous belts 51 which are respectively parallel to the two curtain guide rails 22, a first motor 52 which drives the two synchronous belts 51 to rotate simultaneously through a transmission assembly, two brackets 53 which are respectively arranged on the two synchronous belts 51, and two first sliding rails 54 which respectively guide the two brackets 53 to move along with the walking belts 51, wherein the brackets 53 are provided with clamping blocks 55 which clamp edges of the sunshade curtain. When the two synchronous belts 51 are driven by the first motor 52 to rotate, the two brackets 53 respectively reciprocate horizontally along the two first slide rails 54 along with the synchronous belts 51, and the clamping blocks 55 on the brackets 53 clamp the edges of the sunshade curtain, so that the sunshade curtain is automatically retracted and extended,
in order to detect the torque of the torsion spring of the sunshade curtain during the automatic folding and unfolding process of the sunshade curtain, the first detection mechanism 30 is a force measuring sensor, and one end of the force measuring sensor is arranged on the bracket 53, and the other end of the force measuring sensor is connected with the clamping block 55. When the clamping block 55 clamps the edge strip of the sunshade curtain to drive the curtain to retract and retract, the torsion spring can generate torque, and the force measuring sensor deforms through the clamping block 55, so that the torque of the torsion spring is measured.
When the sunshade curtain is rolled, elastic potential energy is accumulated in the process of releasing the sunshade curtain due to the torsion spring, and in order to avoid the action of the elastic potential energy and the rebound of the edge strip when the sunshade curtain is rolled, the invention is further provided with a baffle column 56 on the bracket 53 for preventing the edge strip of the sunshade curtain from rebounding to the roller shaft of the sunshade curtain, the baffle column 56 is perpendicular to the rolling and releasing direction of the sunshade curtain, the end part of the baffle column 56 is provided with an edge strip clamping groove 57, and the opening direction of the edge strip clamping groove 57 is opposite to the rolling direction of the curtain. It can be seen that the rapid rebound of the edge strips of the shade to the roller of the shade is avoided by the stop post 56.
The second detection mechanism 40 of the present invention is an ultrasonic range finder that can move in the direction of folding and unfolding the sunshade. When the sunshade curtain is opened, the second detecting mechanism 40 moves back and forth under the curtain fabric, and the sagging amount of the curtain fabric can be detected through distance measurement.
