[0050] Furthermore, in the above technical solution, the top of one side of the card plate 42 close to the adjustment plate 3 is set as an inclined surface. When the adjustment plate 3 is pulled downward, the card plate 42 can move to the left after being subjected to force, and quickly move away from the adjustment plate 3, and the bottom of the card plate 42 is still a plane. When the card plate 42 is inserted into the slot 31 again, the free movement of the adjustment plate 3 can be effectively avoided. A plurality of slots 31 are provided on the surface of one side of the adjustment plate 3 close to the card plate 42 from top to bottom. The card plate 42 is connected to the adjustment plate 3 through the slots 31. The user can insert the card plate 42 into a suitable slot 31 according to his own needs, and freely control the extension amount of the adjustment plate 3 to meet his own needs.

[0052] Furthermore, in the above technical solution, the outer surfaces of the plate body 1 and the adjustment plate 3 are connected with a filter film to improve the shading effect of the plate body 1 and the adjustment plate 3, thereby facilitating the use of the user. The bottom of the adjustment plate 3 is connected with a horizontal bar 8, and grooves are provided on both side surfaces of the horizontal bar 8. The user can quickly pull the horizontal bar 8 through the grooves, thereby driving the adjustment plate 3 to move, thereby facilitating the user to pull the adjustment plate 3.

[0053] Furthermore, in the above technical solution, support seats 9 are connected to the left and right sides of the top of the plate body 1, so that the plate body 1 can be quickly installed on the top of the car. A rotating shaft 10 is connected inside the support seat 9. The rotating shaft 10 is set to be L-shaped, and a mounting plate 11 is connected to the top for quickly fixing the sun visor on the top of the car.

[0054] A method for using a car sun visor that can be quickly folded up comprises the following steps:

[0055] S1. Pull out the adjustment plate 3: Flip the plate body 1 downward to provide sunshade. When the sunlight angle is relatively low, the user pulls down the horizontal bar 8 to drive the adjustment plate 3 to move downward along the receiving groove 2 and extend, thereby increasing the shielding area of ​​the plate body 1 in disguised form, so that the shading area of ​​the plate body 1 becomes larger;

[0056] S2. Fixing the position of the adjusting plate 3: When the user pulls the adjusting plate 3 downward, the elastic rope 7 is stretched by force, and at the same time, the inclined surface of the card block is subjected to the downward pressure of the adjusting plate 3, and slides to the left along the accommodating cavity 41, thereby disengaging from the card slot 31 located at the bottom of the adjusting plate 3 and starting to move away from the adjusting plate 3. At this time, the first sliding block also slides to the left along the accommodating cavity 41 along with the movement of the card plate 42, away from the adjusting plate 3, and squeezes the first spring 422, so that the first spring 422 is forced to shrink. When another card slot 31 on the surface of the adjusting plate 3 moves downward to the accommodating cavity 41 along with the adjusting plate 3 and corresponds to the inclined surface of the card plate 42, there is no obstacle on the right side of the card plate 42. Under the action of the elastic force of the first spring 422, the card plate 42 can be rebounded into the card slot 31 to limit the adjusting plate 3, thereby preventing the adjusting plate 3 from being retracted upward due to the elastic force of the elastic rope 7, thereby completing the fixing of the adjusting plate 3.

[0057] S3, adjusting the adjustment plate 3: the user can continue to pull the adjustment plate 3 downward according to his / her own use needs, so that the card plate 42 is inserted into the upper card slot 31, and the extension of the adjustment plate 3 is increased to ensure that the shading area of ​​the plate body 1 meets his / her own needs;

[0058] S4, resetting the plate body 1: when the user no longer needs the plate body 1 to shield light, the user presses the pressing plate 44 and flips the plate body 1 upward to reset the plate body 1;

[0059] S5. Automatic reset of the adjusting plate 3: When the user presses the pressing plate 44, the pressing plate 44 slides upward along the vertical plate 45. As the pressing plate 44 moves, the second sliding block also slides upward along the accommodating cavity 41, and squeezes the second spring 442, so that the second spring 442 is forced to contract. At this time, the rope head of the rope 43 on one side of the pressing plate 44 moves upward as the pressing plate 44 moves, and then pulls the card plate 42 to move to the left, so that the card plate 42 is disengaged from the card slot 31 again and away from the adjusting plate 3. At this time, the adjusting plate 3 is not blocked by the card plate 42, and the elastic force of the elastic rope 7 contracts quickly. It slides upward along the accommodating groove 2 to reset, and when the top of the adjusting plate 3 contacts the rubber pad 5, the slot 31 located at the bottom of the adjusting plate 3 corresponds to the card plate 42 again. At this time, when the user resets the plate body 1 and releases his hand, the pressing plate 44 is reset under the action of the elastic force of the second spring 442, thereby driving the rope head 43 on one side of the pressing plate 44 to move downward. The card plate 42 is no longer subjected to the tension of the rope 43, and under the elastic force of the first spring 422, it can slide to the right again and get into the slot 31, thereby limiting and fixing the adjusting plate 3, and realizing the automatic recovery and reset of the adjusting plate 3.

[0060] Implementation mode, when the present invention is in use, the plate body 1 is fixed on the top of the car through the mounting plate 11. When it is needed, the plate body 1 is rotated downward with the rotating shaft 10 as the rotation center to block the sunlight. When the angle of sunlight is relatively low, the user pulls the adjusting plate 3 to make it extend downward. At this time, the elastic rope 7 is stretched by force, and at the same time, the inclined surface of the card block is subjected to the downward pressure of the adjusting plate 3, and begins to disengage from the card slot 31 and gradually move away from the adjusting plate 3. When another card slot 31 on the surface of the adjusting plate 3 moves downward with the adjusting plate 3 to the accommodating cavity 41 and corresponds to the inclined surface of the card plate 42, the card plate 42 can be rebounded into the card slot 31 under the action of the elastic force of the first spring 422, and the adjusting plate 3 is limited to prevent the adjusting plate 3 from being retracted upward due to the elastic force of the elastic rope 7, thereby completing the fixing of the adjusting plate 3, and then the shielding area of ​​the plate body 1 is increased in disguise, so that the shading area of ​​the plate body 1 becomes larger, so that light with a lower angle can also be blocked by the plate body 1;

[0061] When the user no longer needs the plate body 1 to block light, the user presses the pressure plate 44 and flips the plate body 1 upward to reset the plate body 1. At the same time, after the pressure plate 44 is pressed, it slides upward along the vertical plate 45. At this time, the string 43 pulls the card plate 42 to move left out of the card slot 31 and away from the adjustment plate 3. Under the elastic force of the elastic string 7, the adjustment plate 3 quickly slides upward along the accommodating groove 2 to reset. When the user releases his hand, the pressure plate 44 is reset under the elastic force of the second spring 442. The card plate 42 is no longer subjected to the pulling force of the string 43. Under the elastic force of the first spring 422, it is again clamped into the card slot 31 at the bottom of the adjustment plate 3, and the adjustment plate 3 is limited and fixed, so that the adjustment plate 3 is automatically recovered and reset, and the storage of the plate body 1 can be quickly completed.

[0062] The user can pull the adjustment plate 3 downward according to his / her own use needs, and by pressing the pressing plate 44, the clamping plate 42 is always in a position away from the adjustment plate 3 under the drive of the wire rope 43. At this time, the user can freely pull the adjustment plate 3 up and down, and according to his / her own needs, the clamping plate 42 is clamped into the appropriate clamping slot 31, so that the extension amount of the adjustment plate 3 can be freely controlled, ensuring that the shading area of ​​the plate body 1 meets his / her own needs;

[0063] By providing the direction-changing assembly 47, when the wire rope 43 moves upward with the pressure plate 44, the wire rope 43 can be closely attached to the outer side of the rotating rod 471, and the rotating rod 471 can rotate under the action of friction during the movement of the wire rope 43, thereby changing the moving direction of the wire rope 43 while avoiding direct contact between the wire rope 43 and the side of the baffle 46, thereby preventing the wire rope 43 from breaking, and the circular plates 472 on both sides can prevent the wire rope 43 from escaping from the interior of the direction-changing assembly 47, thereby improving the service life of the wire rope 43;

[0064] The present invention solves the problem in the prior art that in order to increase the shading area of ​​the sun visor, an adjustment plate 3 that can slide downward is provided inside the plate body 1. When the sun visor needs to be folded and closed after use, it is necessary to slide up the adjustment plate 3 first and then close the sun visor body 1, which makes the folding process of the sun visor more complicated and time-consuming, prolongs the time that the closing of the sun visor affects the driver, and may cause traffic accidents.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

When the angle of sunlight is relatively low, the user pulls the horizontal bar (8) downward to drive the adjustment plate (3) to move downward along the receiving groove (2) and extend out, thereby increasing the shielding area of ​​the plate body (1) in disguised form, thereby increasing the shading area of ​​the plate body (1); S2. Fixing the position of the adjustment plate: When the user pulls the adjustment plate (3) downward, the elastic rope (7) is stretched by force, and at the same time, the inclined surface of the card block is pressed downward by the adjustment plate (3), and slides to the left along the accommodating cavity (41), thereby disengaging from the card slot (31) at the bottom of the adjustment plate (3) and starting to move away from the adjustment plate (3). At this time, the first sliding block also slides to the left along the accommodating cavity (41) along with the movement of the card plate (42), away from the adjustment plate (3), and compresses the first spring (422), so that the first spring (422) is moved. The spring (422) contracts under force, and when another slot (31) on the surface of the adjustment plate (3) moves downward with the adjustment plate (3) to the accommodating cavity (41) and corresponds to the inclined surface of the clip plate (42), there is no obstacle on the right side of the clip plate (42) to resist, and under the action of the elastic force of the first spring (422), the clip plate (42) can be rebounded into the slot (31), limiting the adjustment plate (3) and preventing the adjustment plate (3) from being retracted upward due to the elastic force of the elastic rope (7), thereby completing the fixing of the adjustment plate (3); S3, adjusting the adjustment plate: the user can continue to pull the adjustment plate (3) downwards according to his / her own use requirements, so that the card plate (42) is inserted into the upper card slot (31), thereby increasing the extension amount of the adjustment plate (3) and ensuring that the shading area of ​​the plate body (1) meets his / her own needs; S4, resetting the plate body: when the user no longer needs the plate body (1) to block light, the user presses the pressure plate (44) and flips the plate body (1) upward, thereby resetting the plate body (1); S5. Automatic reset of the adjustment plate: When the user presses the pressing plate (44), the pressing plate (44) slides upward along the vertical plate (45), and the second sliding block also slides upward along the accommodating cavity (41) as the pressing plate (44) moves, and squeezes the second spring (442), causing the second spring (442) to contract under force. At this time, the rope end of the rope (43) on one side of the pressing plate (44) moves upward as the pressing plate (44) moves, thereby pulling the card plate (42) to move to the left, so that the card plate (42) is again separated from the card slot (31) and away from the adjustment plate (3). At this time, the adjustment plate (3) is not blocked by the card plate (42) and is quickly retracted under the elastic force of the elastic rope (7). The adjusting plate (3) is reset by sliding upward along the receiving groove (2), and when the top of the adjusting plate (3) contacts the rubber pad (5), the slot (31) at the bottom of the adjusting plate (3) corresponds to the clamping plate (42) again. At this time, when the user resets the plate body (1) and releases his hand, the pressing plate (44) is reset under the action of the elastic force of the second spring (442), thereby driving the rope head of the rope (43) on one side of the pressing plate (44) to move downward. The clamping plate (42) is no longer subjected to the tension of the rope (43), and under the elastic force of the first spring (422), it can slide to the right again and be clamped into the slot (31), thereby limiting and fixing the adjusting plate (3) and realizing automatic recovery and reset of the adjusting plate (3).
