Description

Technical Field

[0001] The utility model relates to the technical field of blackout curtains, in particular to a blackout curtain for a sightseeing elevator car. Background Art

[0002] Observation elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. One or more of the shaft walls and car walls are made of transparent materials, so passengers can see the scenery outside the car while riding the elevator. An elevator in which at least one side of the shaft and car walls are transparent, so passengers can see the scenery outside the car. It is mainly installed in hotels, shopping malls, and high-rise office buildings. One or more of the shaft walls and car walls are made of transparent materials on the same side, so passengers can see the scenery outside the car while riding the elevator. Blackout curtains are installed inside the observation elevator. Blackout curtains are made of opaque or thickened fabrics on the basis of traditional curtains, so as to achieve basic control of light and achieve a blackout effect.

[0003] For example, the Chinese patent "A blackout curtain for a sightseeing elevator car" with announcement number CN205187579U includes a driving mechanism, a curtain and a track for the curtain to run. The driving mechanism includes a tubular motor, a driving wheel, a pulley and a lifting rope. The tubular motors are respectively installed on the top of the car, and the pulleys are arranged at the bottom of the car. Driving wheels are respectively provided at both ends of the tubular motor. The driving wheels and the pulleys are relatively vertically arranged. The driving wheels and the pulleys are connected by a lifting rope. The lifting rope forms a loop that can run up and down with the pulley at the bottom and the driving wheel. Tracks are also provided at both ends of the tubular motor. One end of the curtain is fixedly connected to the lifting rope, and the other end is connected to the tubular motor.

[0004] Although the above-mentioned prior art can achieve shading for sightseeing elevators, in actual use, on the one hand, the roller in the roller-type curtain usually rolls up the entire curtain. After rolling up the entire curtain, the roller bears the weight of the entire curtain, which makes the roller easy to break and the motor is in a loaded state, thereby shortening the service life of the blackout curtain. On the other hand, the blackout curtain needs to be opened manually. When the sun shines, the operator needs to manually open the blackout curtain, resulting in the blackout curtain inside some cars not opening in time, thereby causing the temperature inside the car to rise. Therefore, it does not meet the existing needs. In this regard, we propose blackout curtains for sightseeing elevator cars. Utility Model Content

[0014] Preferably, curtains are provided at the lower end of the connecting ring and inside the mounting ear plate, and the curtains are fixedly connected to the mounting ear plate and the connecting ring respectively.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can extend the blackout curtain in a sliding manner through a double-toothed belt and a motor. When the curtain needs to be extended, the motor is turned on to make the output shaft of the motor drive the driving gear to rotate. At this time, the rotating driving gear drives the double-toothed belt meshing with it to rotate, and the other end of the rotating double-toothed belt drives the transmission gear to rotate. At the same time, the supporting gear keeps the double-toothed belt stable. While the double-toothed belt rotates, the double-toothed belt drives the curtain to move through a driving rod arranged at the lower end. During the movement of the curtain, the curtain itself drives the fixed rod to move, so that the whole curtain is extended, avoiding the driving rod from bearing the curtain in a retracted state, preventing the driving rod from breaking due to the excessive weight of the curtain, and reducing the load of the motor, thereby extending the service life of the motor.

[0017] 2. The utility model can automatically extend and retract the curtains by providing a light sensor. When sunlight shines on the light sensor, the photosensitive element absorbs light energy and generates charge or current. The resistance value of the photoresistor is inversely proportional to the light intensity, while the photodiode generates current, the size of which is proportional to the light intensity. The signal processing circuit will convert the resistance value or current size generated by the photosensitive element into a voltage or digital signal related to the light intensity. The light sensor will then send the signal to the main control module. When the main control module is powered on, the motor will run, causing the motor to drive the curtains to extend, so that the curtains block the sunlight and avoid the operator from opening the curtains in time, thereby improving the comfort of tourists.

[0018] 3. The utility model is provided with a rubber pad, which can provide a certain buffer for the driving rod. When the curtain is extended, the driving rod moves in the sliding cavity through the double-toothed belt until the driving rod drives the curtain to move to the contact of the driving rods on both sides. At this time, the driving rods on both sides contact each other and the rubber pads on the driving rods squeeze each other. The rubber pad absorbs the impact force generated when the driving rod contacts by deformation, avoiding damage caused by direct contact and extrusion of the driving rod, thereby extending the service life of the driving rod.
