Description

Technical Field

[0001] This utility model relates to the field of skylight sunshade technology, specifically a roll-up ceiling sunshade fabric mechanism. Background Technology

[0002] A car sunroof is installed on the roof of the vehicle, which can effectively circulate air inside the car and increase the intake of fresh air. At the same time, the car sunroof can also expand the field of vision and meet the needs of mobile photography and videography. Car sunroofs are equipped with sunshade roller blinds. When the sunroof is not needed to be opened or the sun is in direct sunlight, the sunshade roller blinds can be opened to prevent the sun from shining into the car. When the sunroof needs to be opened or to look out of the car through the sunroof, the sunshade roller blinds need to be rolled up to expose the sunroof.

[0003] For example, the announcement number CN220535373U discloses a sunshade roller blind for a car sunroof, which relates to the field of car sunshade technology. It includes a mounting plate with a cavity inside. The mounting plate has an installation groove on the inner wall of the cavity. Sliding blocks are slidably connected to the corresponding sides of the cavity of the installation groove. A connecting plate is fixedly installed between the two sliding blocks. A first roller is rotatably connected to one side of the cavity of the installation groove.

[0004] The motor in the aforementioned application drives the second roller to rotate, causing the connecting rope to wind around the surface of the second roller. This pulls the connecting plate and moves the sunshade roller blind, simultaneously driving the second pulley to rotate. The cooperation of the second pulley, the first pulley, and the belt ensures that the first and second rollers rotate synchronously. While the connecting plate pulls the sunshade roller blind, the first roller blind is released, maintaining constant force at both ends of the sunshade roller blind and preventing deformation or damage due to prolonged pulling. However, when the sunshade roller blind is unfolded, there is no force on either side, resulting in a loose and unusable design. Therefore, there is an urgent market need to develop a roll-up sunshade fabric mechanism for rooftops to help solve these existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a roll-up sunshade cloth mechanism for the roof, so as to solve the problem mentioned in the background art that when the car sunroof curtain is unfolded, there is no force on both sides, the unfolding is loose, and the use effect is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roll-up ceiling sunshade cloth mechanism, comprising an unfolding mechanism, a rewinding mechanism, a power mechanism, and a clamping mechanism. The unfolding mechanism includes a first lateral movement device and a second lateral movement device. The clamping mechanism is provided in two sets, with each set installed on one side of the first lateral movement device and the second lateral movement device, respectively. The clamping mechanism includes a first fixing plate and a second fixing plate. A first spring is fixedly installed below the first fixing plate, and a first wheel seat is fixedly installed below the first spring. A first pressure roller is rotatably connected below the first wheel seat. A first limiting shaft that is slidably connected to the first fixing plate is fixedly installed above the first wheel seat. A second spring is fixedly installed above the second fixing plate, and a second wheel seat is fixedly installed above the second spring. A second pressure roller is rotatably connected above the second wheel seat, and a second limiting shaft that is slidably connected to the second fixing plate is fixedly installed below the second wheel seat. Several of the first and second pressure roller structures are provided.

[0007] The above technical solution utilizes a clamping mechanism to hold both sides of the roller blind. When the roller blind is unfolded, the two sides of the roller blind are clamped by the first pressure roller and the second pressure roller, so that the two sides of the roller blind are subjected to force, thereby preventing the roller blind from becoming loose. Several first pressure rollers and second pressure rollers are provided, and pressure is applied by springs. Under the action of the springs, the first pressure roller and the second pressure roller can also be squeezed and separated, without interfering with the unfolding and rewinding of the roller blind, thus improving the use effect of the roller blind.

[0008] In a preferred embodiment, the present invention can be further configured as follows: a first lead screw is rotatably connected to the first transverse movement device, a second lead screw is rotatably connected to the second transverse movement device, a first lead screw seat is threaded to the outer side of the first lead screw, a second lead screw seat is threaded to the outer side of the second lead screw, and a pull rod is fixedly installed between the first lead screw seat and the second lead screw seat.

[0009] Through the above technical solution, the rotation of the lead screw drives the lead screw seat to move laterally, and the lead screw seat drives the pull rod to move laterally.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the winding mechanism includes a winding box, a guide roller and a winding roller are rotatably connected inside the winding box, a roller shutter is fixedly connected to the outside of the pull rod, one end of the roller shutter is fixedly connected to the winding roller, a driven wheel is fixedly installed at one end of the winding roller, a first driving device is fixedly installed inside the winding box, a driving wheel is fixedly connected to the driving end of the first driving device, and the driving wheel and the driven wheel are rotatably connected by a belt.

[0011] Through the above technical solution, the pull rod pulls the roller blind to rotate, and the winding roller winds up the retracted roller blind, thus realizing the unfolding and winding of the roller blind.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the power mechanism includes a transmission box, in which a first transmission shaft and a second transmission shaft are rotatably connected respectively; a protective shell is fixedly installed on one side of the transmission box; a second driving device is fixedly installed inside the protective shell; a driving gear is fixedly connected to the driving end of the second driving device; a first driven gear is fixedly installed at one end of the first transmission shaft; a second driven gear is fixedly installed at one end of the second transmission shaft; both the first and second driven gears are meshed with the driving gear; a first output gear is fixedly installed at one end of the first lead screw; a first transmission gear is fixedly installed at one end of the first transmission shaft; the first transmission gear is meshed with the first output gear; a second output gear is fixedly installed at one end of the second lead screw; and a second transmission gear is fixedly installed at one end of the second transmission shaft; the second transmission gear is meshed with the second output gear.

[0013] Through the above technical solution, the second drive device drives the first lead screw and the second lead screw to rotate through the transmission mechanism of the transmission box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model utilizes a clamping mechanism to clamp the two sides of the roller blind. When the roller blind is unfolded, the two sides of the roller blind are clamped by the first pressure roller and the second pressure roller, so that the two sides of the roller blind are stressed, thereby preventing the roller blind from becoming loose. There are several first pressure rollers and second pressure rollers, and pressure is applied by springs. Under the action of the springs, the first pressure roller and the second pressure roller can also be squeezed and separated, without interfering with the unfolding and rewinding of the roller blind, thus improving the use effect of the roller blind.
