AI Technical Summary
Existing sunshade curtains only offer full or partial blackout options, which cannot meet the diverse requirements of customers for different shading needs.
Design a sunshade curtain that combines an opaque first curtain and a semi-transparent second curtain. The degree of fullness of the curtain on the track is controlled by a drive mechanism to achieve switching between full blackout and semi-blackout.
The sunshade curtains can use opaque fabric when complete shading is needed, and semi-transparent fabric when partial shading is needed, thus meeting the diverse shading needs of customers.

Abstract
Description
Technical Field
[0001] This invention relates to a sunshade curtain, and more particularly to a sunshade curtain having two types of fabric. Background Technology
[0002] There are two types of sunshade curtains: one made of completely opaque fabric and the other made of semi-transparent gauze. Currently, no sunshade curtain on the market combines both types of fabric. Therefore, when using them, we either need a completely blackout curtain or a semi-blackout curtain to meet both requirements. Thus, improvement is necessary. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the present invention provides a sunshade curtain with two types of curtain fabric, which includes a semi-transparent gauze and an opaque curtain fabric to meet different customer needs.
[0004] The technical solution adopted by this invention to solve its technical problem is as follows: a sunshade curtain with two types of curtain fabric, including a curtain box and a track. A roller is rotatably connected inside the curtain box, and the roller is driven to rotate by a drive mechanism. One end of the curtain fabric is wound around the roller. One end of the track is located at the bottom of the curtain box, and both ends of the curtain fabric pass through the track. A winding device is also included, located at the other end of the track. A rotating shaft is rotatably connected inside the winding device, and the other end of the curtain fabric is wound around the rotating shaft. The curtain fabric includes an opaque first curtain and a semi-transparent second curtain, with one end of the first and second curtains sewn together. With this sunshade curtain, if complete blackout is required, the drive mechanism can be activated to fill the entire track with the first curtain; if partial blackout is required, the drive mechanism can be activated to fill the entire track with the second curtain. This method allows for the simultaneous use of semi-transparent gauze and opaque curtain fabric to meet different customer needs.
[0005] In the above technical solution, preferably, the retractor has a coil spring, the rotating shaft includes an inner shaft and an outer tube, the other end of the curtain fabric is wound around the outer tube, both ends of the inner shaft are fixed to the ends of the retractor, the outer tube is rotatably connected to the inner shaft, the coil spring is disposed on the inner shaft, one end of the coil spring is fixed together with the inner shaft, and the other end of the coil spring rotates together with the outer tube. The function of the coil spring is to tighten the curtain fabric, so that the fabric is taut after the curtain is pulled out.
[0006] In the above technical solution, preferably, a rotating block is provided at one end of the inner shaft, the rotating block is rotatably connected to the inner shaft, the outer ring of the rotating block is provided with a groove, the inner wall of the outer sleeve is provided with a protrusion that cooperates with the groove, and one end of the coil spring is fixed on the rotating block.
[0007] In the above technical solution, preferably, the first curtain is wound on the winding drum, and the second curtain is wound on the rotating shaft.
[0008] The beneficial effects of this invention are: when complete blackout is required, the drive mechanism can be activated to cover the entire track with the first curtain; when partial blackout is required, the drive mechanism can be activated to cover the entire track with the second curtain. In this way, we can simultaneously have both semi-transparent gauze and opaque curtain fabric to meet different customer needs. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0015] See Figures 1 to 5 A sunshade curtain with two types of curtain fabric includes a curtain box 1 and a track 2. A roller 3 is rotatably connected inside the curtain box 1. The roller 3 is driven to rotate by a drive mechanism 31. One end of the curtain fabric 4 is wound on the roller 3. One end of the track 2 is located at the bottom of the curtain box 1. Both ends of the curtain fabric 4 pass through the track 2.
[0016] It also includes a retractor 5, which is located at the other end of the track 2. A rotating shaft 6 is rotatably connected inside the retractor 5, and the other end of the curtain fabric 4 is wound around the rotating shaft 6.
[0017] The curtain fabric 4 includes an opaque first curtain fabric 41 and a semi-transparent second curtain fabric 42, with one end of the first curtain fabric 41 and the second curtain fabric 42 sewn together.
[0018] The retractor 5 contains a coil spring 7. The rotating shaft 6 includes an inner shaft 61 and an outer tube 62. The other end of the curtain fabric 4 is wound around the outer tube 62. Both ends of the inner shaft 61 are fixed to the ends of the retractor 5. The outer tube 62 is rotatably connected to the inner shaft 61. The coil spring 7 is mounted on the inner shaft 61. One end of the coil spring 7 is fixed together with the inner shaft 61, and the other end of the coil spring 7 rotates together with the outer tube 62. The function of the coil spring is to tighten the curtain fabric, ensuring that the fabric is taut after the curtain is pulled out.
[0019] A rotating block 71 is provided at one end of the inner shaft 61. The rotating block 71 is rotatably connected to the inner shaft 61. A groove 711 is provided on the outer ring of the rotating block 71. A protrusion 621 that cooperates with the groove 711 is provided on the inner wall of the outer sleeve 62. One end of the coil spring 7 is fixed on the rotating block 71.
[0020] The first curtain 4 is wound on the winding drum 3, and the second curtain 42 is wound on the rotating shaft 6.
[0021] This type of sunshade curtain can be used in two ways: to completely block out light, the drive mechanism is activated to cover the entire track with the first curtain; to partially block out light, the drive mechanism is activated to cover the entire track with the second curtain. This allows us to have both semi-transparent gauze and opaque curtain fabric simultaneously, meeting different customer needs.
