The device transmits the power of the motor 11 to the gear speed reducing mechanism 13 through the electromagnetic clutch 12, then drives the winding drum 14 to rotate, and utilizes the forward rotation and reverse rotation functions of the motor 11 to realize the spreading and withdrawing of the sun-shading cloth 15.
When an ignition switch ON of an automobile is closed, a power switch 1 of the roller type automobile built-in sun-shading device is switched ON, a load reducing relay 2 works, and at the moment, a storage battery of an original automobile provides electric energy for the sun-shading device. Therefore, when the ON gear of the ignition switch is not closed, the device does not work due to no power supply current, and the reliability of the device is improved; meanwhile, due to the work of the load reducing relay 2, the working current of the power switch 1 is reduced, and therefore the service life of the power switch 1 is prolonged.
The roller type automobile built-in sunshade device comprises a first group of sunshade device driving circuits and a second group of sunshade device driving circuits. The first group of sunshade device driving circuits comprise a front windshield glass position sunshade switch 8 and a safety 9; the driving circuit of the second group of sunshade devices comprises 4 driver position sunshade switches: the automobile window sunshade device comprises a driver position left front sunshade switch 3, a driver position left rear sunshade switch 4, a driver position right front sunshade switch 5, a driver position right rear sunshade switch 6 and corresponding fuses 9, wherein the switches can respectively control the operation of actuating mechanisms 10 of a left front window, a left rear window, a right front window and a right rear window, and meanwhile, the sunshade switches 4, the sunshade switches 5 and the sunshade switches 6 are respectively connected with the corresponding window position sunshade switches 7 in parallel and can all control the operation of corresponding window sunshade devices; each sunshade switch is a combination switch, preferably a combination switch of a car window control switch type, and includes 2 gears, namely an ascending gear and a descending gear, for controlling the rotation direction of the motor 11, including 2 directions of forward rotation and reverse rotation, so as to control the spreading and retracting of the sunshade cloth 15. When the sunshade cloth 15 is used, the sunshade switch is pressed to lower the gear, when the sunshade cloth 15 falls to a required position, the button is released, and the sunshade cloth 15 is spread; the sunshade switch is pressed to move up, when the sunshade cloth 15 moves up to a required position, the button is released, and the sunshade cloth 15 is retracted. The initial position of the sunshade cloth 15 is a retracted state. When the device has a large-current fault, the fuse 9 is fused for safety protection.
The roller type automobile built-in sun-shading device has the same composition and working principle of two groups of sun-shading device executing mechanisms, and the executing mechanism of the first group of sun-shading device is used for explanation. As shown in fig. 2, the actuator 10 of the first group of sunshade devices includes a motor 11, an electromagnetic clutch 12, a gear reduction mechanism 13, a winding drum 14, and a sunshade cloth 15.

When the electromagnetic clutch 12 is electrified, the power of the motor 11 can be transmitted to the speed reducing mechanism 13, and the device can work; when the device breaks down, the sunshade cloth 15 stays at a certain position and cannot be retracted, the power switch 1 of the device can be disconnected, the electromagnetic clutch 12 is powered off, the connection between the motor 11 and the gear reduction mechanism 13 is disconnected, and the winding drum 14 can be manually rotated to wind the sunshade cloth 15 back to the initial position, so that the sunshade cloth is prevented from blocking the sight of a driver.
In the roll type automobile built-in sunshade device, under the condition of no power supply, the electromagnetic clutch 12 disconnects the motor 11 from the gear speed reducing mechanism 13, at the moment, the roll 14 is rotated to complete the unfolding or the retraction of the sunshade cloth 15 in a manual operation mode, and at the moment, the work of the device is changed from automatic operation to manual operation.
The working characteristics of the device are as follows: when the sunshine of the front windshield glass needs to be shielded, the sun-shading switch 8 of the driver position is switched on; if the sun-shading device of a certain vehicle window needs to be controlled, a driver position left front sun-shading switch 3, a driver position left rear sun-shading switch 4, a driver position right front sun-shading switch 5 and a driver position right rear sun-shading switch 6 can be pressed; the passengers in the vehicle can also operate the sunshade switches 7 of the left rear window, the right front window and the right rear window to realize the sunshade of different windows.
When the device has a fault, for example, the sun-shading cloth stays at a certain position and cannot be retracted, the power switch 1 of the device can be switched off, and the winding drum 14 is manually rotated to wind the sun-shading cloth 15 back to the initial position, so that the sight of a driver is prevented from being shielded.
In the roll type automobile built-in sunshade device, under the condition of no power supply, the electromagnetic clutch 12 disconnects the motor 11 from the gear speed reducing mechanism 13, and at the moment, the sunshade cloth 15 can be unfolded or retracted by rotating the roll 14 in a manual operation mode.
