The present application may be an embodiment implemented in other ways. Moreover, it should be understood that the words and terms used herein are only used for descriptive purposes and should not be interpreted restrictively. The words "including", "comprising", "having" and the like used herein are meant to include the items listed thereafter, their equivalents and other additional items. In particular, when describing "a certain element", the present application does not limit the number of the element to one, but may also include multiple elements.

[0025] Please also refer to Figures 1 to 7 As shown, the present application provides a sunroof shading device 10, which can be installed on the roof sunroof of a car to achieve the shielding or exposure of the sunroof. The sunroof shading device 10 includes a frame body 12 and a sunshade 14 provided on the frame body 12, a transmission mechanism, and an automatic reset mechanism, wherein the transmission mechanism needs to be driven by electric energy, and the automatic reset mechanism is driven by mechanical energy. The frame body 12 is provided with a window 16 corresponding to the sunroof, and the sunshade 14 can move relative to the window 16 to block or expose the window 16. For example, the sunshade 14 is movably provided on one side of the window 16 and can be switched between a closed state and an open state, thereby achieving the shielding or exposure of the sunroof. The transmission mechanism is used to provide the power required by the sunshade 14 during the closing process, and the automatic reset mechanism is used to provide the restoring force required by the sunshade 14 during the opening process.

[0026] The frame body 12 can be fixedly installed on the inner side of the roof sunroof of the car, and the transmission mechanism and the automatic reset mechanism are both arranged on the side of the frame body 12 away from the interior space of the car, which can be hidden to avoid exposure and affect the appearance. For example, a mounting frame 13 is arranged around the window 16 on the side of the frame body 12 away from the interior space of the car, and the transmission mechanism and the automatic reset mechanism are both arranged on the mounting frame 13. The sunroof sunshade device 10 of the present application has a simple structure and is energy-saving. By arranging the transmission mechanism and the automatic reset mechanism, the sunshade curtain 14 only needs to be driven by electric energy during the closing process, and the opening process can be achieved by the mechanical energy of the automatic reset mechanism without using electric energy, thereby effectively saving electric energy.

[0027] In the illustrated embodiment, the sunshade 14, the transmission mechanism and the automatic reset mechanism are each provided in two groups, and the two groups of structures are symmetrically arranged about the center line of the length direction of the frame body 12. Only one group of structures is described in detail below.

[0028] Specifically, the frame body 12 is a hollow square frame structure, and the sunshade 14 is made of a material that can be rolled up, such as cloth, and the sunshade 14 can move relative to the mounting frame 13 on one side of the window 16. The sunshade 14 has a relative movable end 18 and a storage end 20 in the length direction of the window 16. The movable end 18 is connected to the transmission mechanism and can move between a closed position a and an open position b. The closed position a and the open position b are arranged at intervals along the length direction of the frame body 12. For example, the closed position a is located in the middle of the window 16, and the open position b is located at the end of the window 16. The storage end 20 can be connected to the automatic reset mechanism in a rollable manner. When the movable end 18 moves between the closed position a and the open position b, the storage end 20 performs a corresponding rolling and storage action or reversely rolls back outward.

[0029] When the movable end 18 is at the closed position a, the sunshade 14 is in a closed state; when the movable end 18 is at the open position b, the sunshade 14 is in an open state. The transmission mechanism provides the movable end 18 with power to move toward the closed position a, and the automatic reset mechanism continuously applies a restoring force to the movable end 18 to move it toward the open position b.

[0030] In the illustrated embodiment, the transmission mechanism includes a motor 22 located at the open position b, a sliding frame 24 that can slide between the closed position a and the open position b, and a pulley assembly connected between the motor 22 and the sliding frame 24, wherein the motor 22 and the sliding assembly are respectively provided in two groups and are respectively fixedly provided on opposite side walls of the mounting frame 13, the sliding frame 24 extends along the width direction of the window 16, and the movable end 18 is fixedly connected to the sliding frame 24, for example, by adhesive connection. The pulley assembly includes a first fixed pulley 26 driven and connected to the motor 22, a second fixed pulley 28 located at the closed position a, a transmission member 30 fixedly connected to the sliding frame 24, a movable pulley 32 located on the sliding frame 24, and a traction rope connected between the first fixed pulley 26, the second fixed pulley 28, and the movable pulley 32, wherein one end of the traction rope is fixed to the first fixed pulley 26, and the other end passes around the second fixed pulley 28 and is fixed around the movable pulley 32, so that the movable pulley 32 can drive the transmission member 30 to move between the closed position a and the open position b. The number of movable pulleys 32 is not limited, for example, two are provided, and the second fixed pulley 28 can be rotatably fixed on the inner side wall of the mounting frame 13 through a fixing member. The transmission member 30 is located outside the end of the sliding frame 24, and includes a base 34 and a pulley mounting portion 36 and a fixing portion 38 provided on opposite sides of the base 34, the pulley mounting portion 36 is located on a side of the base 34 away from the sliding frame 24, and the fixing portion 38 is located on a side of the base 34 close to the sliding frame 24, the movable pulley 32 is rotatably fixed to the pulley mounting portion 36, and the fixing portion 38 is fixedly connected to the sliding frame 24, for example, by screws.

[0031] Furthermore, a slide rail 40 is provided on the inner side wall in the width direction of the mounting frame 13, and the transmission member 30 includes a guide sliding portion 42 provided on the side of the base 34 away from the slide frame 24, and the guide sliding portion 42 can be slidably fitted in the slide rail 40. In order to reduce the friction resistance between the guide sliding portion 42 and the guide rail 40, the height of the middle portion of the guide sliding portion 42 in the sliding direction is set to be higher than the height of the two sides, so that only the middle region of the guide sliding portion 42 generates friction with the slide rail 40, thereby increasing the sliding smoothness of the transmission member 30.

[0032] Preferably, the transmission member 30 is provided with a sensing member 44, the frame body 12 is provided with a first sensor 46 for sensing the sensing member 44 at the closed position a, and the frame body 12 is provided with a second sensor 48 for sensing the sensing member 44 at the open position b. The sensing member 44 is, for example, arranged at the top of the pulley mounting portion 36, and the first sensor 46 and the second sensor 48 are, for example, fixedly arranged on the top wall of the mounting frame 13. The sensing member 44 is, for example, a magnet, and the first sensor 46 and the second sensor 48 are, for example, position sensors such as Hall sensors. When the first sensor 46 senses the sensing member 44, it indicates that the transmission member 30 and the movable end 18 have moved to the closed position a, and it can be determined that the sunshade 14 is in a closed state at this time; when the second sensor 48 senses the sensing member 44, it indicates that the transmission member 30 and the movable end 18 have moved to the open position b, and it can be determined that the sunshade 14 is in an open state at this time. In other embodiments, a position sensor can also be provided in the area between the closed position a and the open position b on the frame body 12 to determine the position information of the sunshade 14.

[0033] Preferably, the transmission mechanism further includes a locking structure, which is used to lock the movable end 18 at any moving position, so that the sunshade 14 can overcome the restoring force of the automatic reset mechanism and partially open or partially close the window 16, or the sunshade 14 can overcome the restoring force of the automatic reset mechanism and stably stay in the open state. In this embodiment, the locking structure is the driving end of the motor 22. When the motor 22 stops rotating, the driving end can stop the first fixed pulley 26 from rotating, thereby achieving the function of locking the movable end 18 so that it cannot move.

[0034] In the illustrated embodiment, the automatic reset mechanism is disposed on the side of the open position b away from the closed position a, and the automatic reset mechanism comprises a fixed rod 50, a rotating drum 52 rotatably disposed on the fixed rod 50, and a reset member 54 wound on the fixed rod 50, and the storage end 20 is woundly connected to the rotating drum 52. Two fixed rods 50 may be provided, and the two fixed rods 50 are respectively fixedly connected to the two opposite inner side walls in the width direction of the mounting frame 13, and the two ends of the rotating drum 52 are respectively rotatably sleeved on the two fixed rods 50, and the two fixed rods 50 are respectively provided with a stopper on the side away from each other to limit the rotating drum 52 to prevent the rotating drum 52 from shaking in the width direction of the frame body 12. The reset member 54 is, for example, a torsion spring. Two reset members 54 are provided and are respectively sleeved on the two fixed rods 50. One end of the reset member 54 is fixedly connected to the fixed rod 50, and the other end is fixedly connected to the inner wall of the rotating drum 52, so as to apply elastic bias to the rotating drum 52 in the direction of winding the sunshade 14 onto the rotating drum 52. When the sunshade 14 is in the closed state, the reset member 54 is in a deformed state, so as to apply a restoring force to the movable end 18 to move it toward the open position b.

[0035] In the illustrated embodiment, a controller 56 is further provided on the frame body 12, and the controller 56 is used to control the sunshade curtain 14 to switch between the closed state and the open state. The controller 56 is electrically connected to the motor 22, and the controller 56 may include control modes such as key control, remote control, and voice interaction control. The controller 56 may be provided on the side of the frame body 12 facing the interior space of the vehicle for user operation and control. The controller 56 may be used to control the two sunshades 14 to be opened or closed separately or synchronously.

[0036] Preferably, a power supply electrically connected to the controller 56 and a solar panel 58 electrically connected to the power supply are provided in the frame body 12. The solar panel 58 can be arranged on the side of the frame body 12 facing the outside of the vehicle and located in the sunroof area to receive sunlight and convert solar energy into electrical energy and store it in the power supply, thereby realizing the conversion and utilization of green energy and reducing the power consumption of the vehicle.

[0037] The operation process of the sunroof sunshade device 10 is briefly described below: when the sunshade curtain 14 is in the closed state, the motor 22 stops rotating, and the motor 22 keeps the first fixed pulley 26 at the current position without rotating, and the reset member 54 is in a deformed state at this time; after receiving the command to open the sunshade curtain 14, the motor 22 is controlled to release the first fixed pulley 26, and the rotating drum 52 is driven to rotate under the restoring force of the reset member 54, and the movable end 18 moves from the closed position a to the open position b, so that the sunshade curtain 14 is wound on the rotating drum 52. After receiving the command to close the sunshade curtain 14, the motor 22 is driven to rotate the first fixed pulley 26 and pull the movable pulley 32 and the movable end 18 to the closed position a through the traction rope until the sunshade curtain 14 is closed, and the motor 22 stops rotating and locks the first fixed pulley 26.

[0038] In summary, the present application provides a sunroof shading device, including a frame body and a sunshade curtain, a transmission mechanism, and an automatic reset mechanism arranged on the frame body. The frame body is provided with a window, and the sunshade curtain can move relative to the window to block or expose the window.
