Description

Technical Field

[0001] This invention relates to the field of automotive equipment technology, specifically to an adjustable car cabin sunshade device. Background Technology

[0002] Car sunshades can be categorized into three types based on their location: front sunshade, side sunshade, and rear sunshade. Direct sunlight entering the car raises the temperature and can also impair the driver's visibility. The purpose of a car sunshade is to block direct sunlight, making the interior of the car more comfortable.

[0003] Chinese Patent CN106274398B discloses a car sunshade, belonging to the field of automotive equipment technology. It solves the problem of poor sunshade performance in existing car sunshades. This car sunshade includes a fixed rod for installation on the car windshield and a lifting rod located below the fixed rod. The fixed rod and the lifting rod are connected by a linkage assembly that allows the lifting rod to move up and down. A curtain is connected between the fixed rod and the lifting rod. The upper edge of the fixed rod has an upward-facing recess located at the middle of the length of the fixed rod. The two ends of the lifting rod are also provided with side curtains that can unfold to the sides when the lifting rod is lowered. This car sunshade provides more comprehensive sun protection for the car's windshield and has a better sunshade effect.

[0004] The above solution still has the following problems in practical application:

[0005] Traditional car sunshades (such as the above solution) use a roller to pull down the sunshade cloth to block the sun from the car window. However, different car windows are not all the same size and shape, and traditional sunshades are difficult to fit the windows of various car models. Moreover, car windows are irregular in shape, so when traditional sunshades are used, there will be certain areas of the window that are not covered.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides an adjustable car cabin sunshade device. Through the configuration of the drive mechanism, the area of ​​the sunshade cloth can be comprehensively increased or decreased, making the device suitable for sunshades on windows of different car models. Furthermore, the upper and lower drive components in the drive mechanism allow for area adjustment and shape transformation of the sunshade cloth, making the device suitable for sunshades of various shapes and sizes. This solves the problems of traditional sunshades being unable to match the windows of various car models and failing to cover irregularly shaped windows.

[0009] Technical solution

[0010] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0011] An adjustable car cabin sunshade device includes a sunshade cloth, four brackets, a support rod, and a drive device.

[0012] The sunshade fabric includes an inner layer and an outer layer, with the inner layer being fitted inside the outer layer.

[0013] The bracket includes a rotating support plate and a movable support plate. The movable support plate is located on one side of the top of the rotating support plate and the two slide against each other. The rotating support plate is connected to the inner layer fabric, and the movable support plate is connected to the outer layer fabric.

[0014] The driving device is sleeved on the outer periphery of the support rod. The driving device includes an upper driving member and a lower driving member. The upper driving member and the lower driving member are slidably engaged. The driving device and the movable support plate are provided with a connecting component in the middle. The upper driving member drives two adjacent movable support plates to move through the connecting component. The lower driving member drives two other adjacent movable support plates to move through the connecting component.

[0015] The driving device moves upward around the outer periphery of the support rod, and through the connecting assembly, drives four movable support plates to move outward simultaneously, thereby causing the entire outer layer fabric to open. The upper driving member moves upward around the outer periphery of the support rod, and through the connecting assembly, drives two adjacent movable support plates to move outward, thereby causing the upper half of the outer layer fabric to open. The lower driving member moves upward around the outer periphery of the support rod, and the sleeve connecting assembly drives two other adjacent movable support plates to move outward, thereby causing the lower half of the outer layer fabric to open.

[0016] Preferably, a connector is fixedly provided at the top of the support rod, and a plurality of brackets are evenly arranged on the outer periphery of the connector and hinged to the connector.

[0017] Preferably, the connecting assembly includes a connecting plate and a movable plate, and a connecting block disposed in the middle of the connecting plate and the movable plate. One end of the connecting plate is hinged to the bottom of the movable support plate, and one end of the movable plate is hinged to the driving device. A connecting rod and a movable rod are fixedly provided at both ends of the connecting block, and the connecting rod and the movable rod are slidably engaged with the connecting plate and the movable plate, respectively. During the upward movement of the support rod on the outer periphery, the driving device drives the movable support plate to move outward on the surface of the rotating support plate through the hinges between the movable plate and the connecting plate and the driving device and the movable support plate, respectively.

[0018] Preferably, the movable plate has a sliding groove at the end away from the driving device, one end of the movable rod is slidably disposed in the inner cavity of the sliding groove and at the opening of the sliding groove, the end of the movable rod away from the connecting block is provided with a first spring, the connecting plate has a sliding groove at the end away from the movable support plate, one end of the connecting rod is slidably disposed in the inner cavity of the sliding groove and at the bottom of the sliding groove, and the end of the connecting rod away from the connecting block is provided with a second spring.

[0019] Preferably, the upper drive member has a guide rail groove on one side near the lower drive member, and a guide rail block is fixedly connected to the other side. The lower drive member has a guide block that slides with the guide rail groove on one side near the upper drive member, and a guide groove that slides with the guide rail block on the other side. Both the upper and lower drive members are threaded with fixing screws to the support rod. The fixing screws control the fixation and displacement of the drive device.

[0020] Preferably, a guide groove is provided on one side of the top of the rotating support plate, and the movable support plate is slidably disposed in the inner cavity of the guide groove and one end extends out of the rotating support plate.

[0021] Preferably, a rectangular sleeve is fitted around the outer periphery of the driving device, and limiting blocks are fixedly provided on both sides of the inner cavity of the rectangular sleeve. Limiting grooves are opened on both sides of the outer periphery of the driving device, and the two limiting grooves are respectively opened on the outer periphery of the upper driving member and the lower driving member. The limiting blocks are slidably disposed in the inner cavity of the limiting grooves. A fixing screw is threaded on the outer periphery of the rectangular sleeve. The fixing screw passes through the rectangular sleeve and the limiting blocks in the inner cavity of the rectangular sleeve and contacts the outer periphery of the support rod.

[0022] Preferably, the rectangular sleeve and the rotating support plate are provided with two sets of hinge components in the middle, the two sets of hinge components are installed side by side, and the connecting component is located between the two sets of hinge components. The hinge component includes a hinge plate, and the two ends of the hinge plate are respectively hinged to the rotating support plate and the rectangular sleeve. During the upward movement of the rectangular sleeve, the hinge component drives the rotating support plate to rotate upward, so that the sunshade cloth is opened.

[0023] Preferably, a fixed shaft is fixed between the two hinge plates, and the connecting block is rotatably connected to the hinge plates through the fixed shaft.

[0024] Beneficial effects

[0025] Compared with the prior art, the present invention provides an adjustable car cabin sunshade device, which has the following beneficial effects:

[0026] 1. This invention utilizes the sliding cooperation between the upper and lower driving components to allow the driving device to be operated as a whole or separately. When the driving device moves upward on the support rod as a whole, it drives the four movable support plates to move outward synchronously away from each other through the connecting components, so that the outer layer of fabric is fully unfolded. When the driving device is operated separately, the upper driving component moves the two movable support plates above the sunshade cloth outward synchronously, so that the outer layer of fabric above the sunshade cloth is unfolded. The lower driving component moves the two movable support plates below the sunshade cloth outward synchronously, so that the outer layer of fabric below the sunshade cloth is unfolded. This solves the problem that traditional sunshades are difficult to match the window sunshades of various car models and difficult to cover various irregular windows.

[0027] 2. The present invention allows the hinges between the two ends of the connecting component and the driving device and the movable support plate, the hinges between the two ends of the hinge and the rotating support plate and the rectangular sleeve, and the hinge between the bracket and the connecting component to swing left and right. This allows the angles of the four brackets to be adjusted slightly after the sunshade is unfolded, so that the endpoints of the four movable support plates can be located at the four corners of the car windshield. This results in a larger area covered by the sunshade on the car window and a better fit between the two.

[0028] 3. The present invention uses a connecting component installed in the middle of two hinge components and a fixed shaft to connect the connecting component and the two hinge components, so that the connecting component and the two hinge components can rotate. This ensures that the connecting component will not interfere with the operation of the hinge components during the opening and closing of the sunshade. At the same time, after the sunshade is opened, the bracket is fixed, which fixes the rotating support plate. This allows the connecting component to operate the moving support plate on the rotating support plate independently, so that the two components can be operated synchronously or independently.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an adjustable car cabin sunshade device.

[0041] Please see Figure 1 An adjustable car cabin sunshade device includes a sunshade cloth 1, four brackets 2, a support rod 3, and a drive device 4.

[0042] The sunshade fabric 1 includes an inner layer fabric 101 and an outer layer fabric 102, with the inner layer fabric 101 being fitted inside the outer layer fabric 102;

[0043] The support 2 includes a rotating support plate 201 and a movable support plate 202. The movable support plate 202 is located on one side of the top of the rotating support plate 201 and the two slide against each other. The rotating support plate 201 is connected to the inner layer fabric 101, and the movable support plate 202 is connected to the outer layer fabric 102.

[0044] The drive device 4 is sleeved on the outer periphery of the support rod 3. The drive device 4 includes an upper drive member 41 and a lower drive member 42. The upper drive member 41 and the lower drive member 42 are slidably engaged. A connecting component 5 is provided in the middle of the drive device 4 and the movable support plate 202. The upper drive member 41 drives two adjacent movable support plates 202 to move through the connecting component 5. The lower drive member 42 drives two other adjacent movable support plates 202 to move through the connecting component 5.

[0045] The drive device 4 moves upward around the support rod 3, and through the connecting component 5 drives the four movable support plates 202 to move outward and expand simultaneously, thereby causing the entire outer layer fabric 102 to open. The upper drive member 41 moves upward around the support rod 3, and through the connecting component 5 drives two adjacent movable support plates 202 to move outward and expand, thereby causing the upper half of the outer layer fabric 102 to open. The lower drive member 42 moves upward around the support rod 3, and the connecting component 5 drives the other two adjacent movable support plates 202 to move outward and expand, thereby causing the lower half of the outer layer fabric 102 to open.

[0046] Specifically, since the front and rear windows of a car are irregularly rectangular, and the shape and size of a conventional sunshade are fixed, the size and shape of the sunshade 1 need to be changed according to the shape of the windows during actual use. Therefore, this device has two areas on the sunshade 1: an upper area and a lower area (corresponding to the top and bottom of the sunshade 1). When the upper drive member 41 runs, it drives the two movable support plates 202 of the upper area to move, thereby changing the area of ​​the upper area of ​​the sunshade 1. When the lower drive member 42 runs, it drives the two movable support plates 202 of the lower area to move, thereby changing the area of ​​the lower area of ​​the sunshade 1. The area of ​​the sunshade 1 is changed by the movement of the upper and lower movable support plates 202 simultaneously driven by the operation of the drive device 4. Since the four supports 2 are in a cross shape, the shape of the sunshade 1 can be changed by adjusting the movable support plates 202 of the upper and lower regions. When the sunshade 1 is fully opened, the lower drive member 42 moves downward, causing the two movable support plates 202 of the lower region to move inward, thereby shortening the lateral distance of the lower region and changing the shape of the entire sunshade 1, so that the shape of the sunshade 1 is more in line with the shape of the car window.

[0047] Specifically, when it is necessary to increase the area of ​​the entire sunshade cloth 1, the drive device 4 is driven to move upward on the support rod 3, thereby causing the movable support plate 202 on the four supports 2 to move. The movable support plate 202 moves towards one end of the rotating support plate 201, thereby causing the outer layer cloth 102 to expand outward, thereby increasing the area of ​​the entire sunshade cloth 1.

[0048] When it is necessary to increase the area of ​​the upper region of the sunshade cloth 1, the upper driving member 41 and the lower driving member 42 in the driving device 4 slide together, causing the upper driving member 41 to move upward. This causes the two movable support plates 202 of the upper region of the sunshade cloth 1 to move through the connecting component 5, thereby causing the outer layer cloth 102 of the upper region of the sunshade cloth 1 to expand outward and increase the area of ​​the upper region of the sunshade cloth 1. Similarly, when the lower driving member 42 moves upward, the area of ​​the lower region is increased.

[0049] When it is necessary to change the shape of the sunshade 1, since the shapes of the front and rear windows of the car are not exactly the same and are not regular rectangles, after the sunshade 1 is fully unfolded, the lower drive component 42 is driven to move downward as needed, thereby driving the two moving support plates 202 in the lower area to move inward, thus making the lower area of ​​the sunshade 1 smaller, so that the sunshade 1 as a whole forms a rectangular shape, making the sunshade 1 fit the car window better.

[0050] The drive unit 4 operates as a whole, causing the four movable support plates 202 to move outward synchronously away from each other, so that the outer layer cloth 102 is fully unfolded. When the drive unit 4 operates separately, the upper drive member 41 operates alone to move the two movable support plates 202 above the sunshade cloth 1 outward synchronously, so that the outer layer cloth 102 above the sunshade cloth 1 is unfolded. The lower drive member 42 operates alone to move the two movable support plates 202 below the sunshade cloth 1 outward synchronously, so that the outer layer cloth 102 below the sunshade cloth 1 is unfolded. This solves the problem that traditional sunshades are difficult to match the window sunshades of various car models and difficult to cover various irregular windows.

[0051] Further, please refer to Figure 7 For the aforementioned bracket 2, a connector 7 is fixedly provided at the top of the support rod 3. Multiple brackets 2 are evenly arranged on the outer periphery of the connector 7 and are hinged to the connector 7. The bracket 2 can rotate with the connector 7 and swing left and right at a certain angle.

[0052] Further, please refer to Figure 4 For the aforementioned connecting component 5, the connecting component 5 includes a connecting plate 51 and a movable plate 52, and a connecting block 53 located in the middle of the connecting plate 51 and the movable plate 52. One end of the connecting plate 51 is hinged to the bottom of the movable support plate 202, and one end of the movable plate 52 is hinged to the driving device 4. The two ends of the connecting block 53 are respectively fixed with a connecting rod 54 and a movable rod 55. The connecting rod 54 and the movable rod 55 are respectively slidably engaged with the connecting plate 51 and the movable plate 52. During the upward movement of the support rod 3, the driving device 4 drives the movable support plate 202 to move outward on the surface of the rotating support plate 201 through the hinge between the movable plate 52 and the connecting plate 51 and the driving device 4 and the movable support plate 202 respectively.

[0053] Specifically, when the drive device 4 moves upward, it drives one end of the movable rod 55 to move upward. The connecting block 53 is the hinge center of the movable plate 52 and the connecting plate 51. When the movable rod 55 rotates around the connecting block 53, it drives the connecting rod 54 to rotate downward around the connecting block 53. At this time, through the sliding fit between the connecting rod 54 and the connecting plate 51, and the sliding fit between the movable plate 52 and the movable rod 55, the drive device 4 moves upward and drives the movable support plate 202 to move horizontally on the rotating support plate 201.

[0054] The movable plate 52 can swing slightly left and right while rotating with the drive device 4, and the connecting plate 51 can swing slightly left and right while rotating with the movable support plate 202, so that the device can adjust the angle between two adjacent supports 2 slightly.

[0055] Further, please refer to Figure 4 For the aforementioned connecting component 5, the movable plate 52 has a sliding groove 56 at the end away from the driving device 4, the movable rod 55 has one end slidably disposed in the inner cavity of the sliding groove 56 and located at the opening of the sliding groove 56, the movable rod 55 has a first spring 57 at the end away from the connecting block 53, the connecting plate 51 has a sliding groove 58 at the end away from the movable support plate 202, the connecting rod 54 has one end slidably disposed in the inner cavity of the sliding groove 58 and located at the bottom of the sliding groove 58, and the connecting rod 54 has a second spring 59 at the end away from the connecting block 53;

[0056] When the drive device 4 moves upward, the movable rod 55 and the movable plate 52 are in a contracted state, that is, the distance between the connecting block 53 and the movable plate 52 decreases. At this time, the first spring 57 is in a compressed state, and the connecting plate 51 and the connecting rod 54 are in an extended state, that is, the distance between the connecting plate 51 and the connecting block 53 increases. At this time, the second spring 59 is in a decompressed state. The elastic force provided by the second spring 59 increases the distance between the connecting plate 51 and the connecting block 53 and provides a driving force for the displacement of the movable support plate 202.

[0057] Further, please refer to Figure 6 The upper drive member 41 has a guide rail groove 44 on one side near the lower drive member 42, and a guide rail block 43 is fixedly connected to the other side. The lower drive member 42 has a guide block 45 that slides with the guide rail groove 44 on one side near the upper drive member 41, and a guide groove 46 that slides with the guide rail block 43 on the other side. Both the upper drive member 41 and the lower drive member 42 are threaded with fixing screws between themselves and the support rod 3. The fixing screws control the fixation and displacement of the drive device 4.

[0058] By setting the guide block 43 and the guide groove 44, the upper drive member 41 and the lower drive member 42 can slide relative to each other, thereby realizing the individual movement of the upper drive member 41 and the lower drive member 42.

[0059] Further, please refer to Figure 2 For the aforementioned movable support plate 202, a guide groove 203 is provided on one side of the top of the rotating support plate 201, and the movable support plate 202 is slidably disposed in the inner cavity of the guide groove 203 and one end extends to the outside of the rotating support plate 201.

[0060] Specifically, by setting the guide groove 203, the movable support plate 202 and the rotating support plate 201 form a telescopic rod structure, so that the movable support plate 202 can move smoothly on the upper surface of the rotating support plate 201, thereby adjusting the size of the sunshade cloth 1. The outer layer cloth 102 is connected to the end of the movable support plate 202 away from the connector 7. The length of the movable support plate 202 is longer than the length of the guide groove 203, so that when the sunshade cloth 1 is fully opened, the area of ​​the sunshade cloth 1 can be reduced when the driving device 4 is moved downward.

[0061] Further, please refer to Figure 6 and Figure 7 For the aforementioned drive device 4, a rectangular sleeve 8 is fitted around the outer periphery of the drive device 4. Limiting blocks 9 are fixedly provided on both sides of the inner cavity of the rectangular sleeve 8. Limiting grooves 10 are opened on both sides of the outer periphery of the drive device 4. The two limiting grooves 10 are respectively opened on the outer periphery of the upper drive member 41 and the lower drive member 42. The limiting blocks 9 are slidably disposed in the inner cavity of the limiting grooves 10. The outer periphery of the rectangular sleeve 8 is threaded with fixing screws. The fixing screws pass through the rectangular sleeve 8 and the limiting blocks 9 in the inner cavity of the rectangular sleeve 8, and contact the outer periphery of the support rod 3.

[0062] The rectangular sleeve 8 is installed on the top of the outer periphery of the drive device 4. The top of the drive device 4 is provided with a protruding plate, that is, the top of both the upper drive member 41 and the lower drive member 42 are provided with protruding plates. The protruding plates are located on the top of the rectangular sleeve 8, so that when the rectangular sleeve 8 moves upward and expands the device, it can drive the drive device 4 to move synchronously, so that the drive device 4 and the rectangular sleeve 8 are in a relatively stationary state, that is, when the rectangular sleeve 8 moves, the drive device 4 will not drive the moving support plate 202 to move.

[0063] Further, please refer to Figure 8 For the aforementioned rotating support plate 201, the rectangular sleeve 8 and the rotating support plate 201 are provided with two sets of hinge components 6 in the middle. The two sets of hinge components 6 are installed side by side, and the connecting component 5 is located between the two sets of hinge components 6. The hinge component 6 includes a hinge plate 62. The two ends of the hinge plate 62 are respectively hinged to the rotating support plate 201 and the rectangular sleeve 8. During the upward movement of the rectangular sleeve 8, the rotating support plate 201 is driven to rotate upward through the hinge component 6, so that the sunshade cloth 1 is opened.

[0064] The hinge plate 62 can rotate and swing slightly left and right while rotating with the rectangular sleeve 8, and the hinge plate 62 can rotate and swing slightly left and right while rotating with the rotating support plate 201, so that the device can adjust the angle between two adjacent supports 2 slightly.

[0065] Further, please refer to Figure 8 For the aforementioned connecting component 5, a fixed shaft 61 is fixedly provided between the two hinge plates 62, and the connecting block 53 is rotatably connected to the hinge plate 62 through the fixed shaft 61.

[0066] Specifically, the connecting component 5 and the hinge component 6 are connected by setting the fixed shaft 61, so that the connecting component 5 is located between the two hinge components 6 and the two are in a parallel state. When the driving device 4 is needed to expand the area of ​​the sunshade cloth 1, the two are in a staggered state.

[0067] Working principle: When in use, the rectangular sleeve 8 is pushed upward, thereby driving the entire drive device 4 and the rectangular sleeve 8 to move upward synchronously. Through the hinges between the two ends of the hinge plate 62 in the hinge assembly 6 and the rotating support plate 201 and the rectangular sleeve 8 respectively, the hinge between the movable plate 52 in the connecting assembly 5 and the drive device 4, the hinge between the connecting plate 51 and the movable support plate 202, and the hinge between the bracket 2 and the connecting piece 7, the bracket 2 is driven to rotate upward, thereby opening the four brackets 2, and thus fully opening the sunshade cloth 1. At this time, the rectangular sleeve 8 is fixed by fixing screws.

[0068] Specifically, when it is necessary to increase the area of ​​the overall sunshade cloth 1, the user drives the overall drive device 4 upward. The movable rod 55 and the movable plate 52 are in a contracted state, that is, the distance between the connecting block 53 and the movable plate 52 decreases. At this time, the first spring 57 is in a compressed state, and at the same time, the connecting plate 51 and the connecting rod 54 are in an extended state, that is, the distance between the connecting plate 51 and the connecting block 53 increases. At this time, the second spring 59 is in a decompressed state. The elastic force provided by the second spring 59 increases the distance between the connecting plate 51 and the connecting block 53 and provides a pushing force for the displacement of the movable support plate 202, thereby causing the movable support plate 202 to move relatively parallel on the surface of the rotating support plate 201, thereby driving the outer layer cloth 102 to move outward, thereby increasing the overall area of ​​the sunshade cloth 1.

[0069] When it is necessary to adjust the area of ​​the sunshade cloth 1, the user pushes the upper drive member 41, the upper drive member 41 moves upward, the movable rod 55 and the movable plate 52 are in a contracted state, that is, the distance between the connecting block 53 and the movable plate 52 decreases. At this time, the first spring 57 is in a compressed state, and at the same time, the connecting plate 51 and the connecting rod 54 are in an extended state, that is, the distance between the connecting plate 51 and the connecting block 53 increases. At this time, the second spring 59 is in a decompressed state. The elastic force provided by the second spring 59 increases the distance between the connecting plate 51 and the connecting block 53 and provides a pushing force for the displacement of the movable support plate 202, thereby causing the movable support plate 202 to move outward relatively parallel to the surface of the rotating support plate 201, thereby increasing the area of ​​the sunshade cloth 1. Similarly, when it is necessary to reduce the area of ​​the sunshade cloth 1, the upper drive member 41 is pushed downward.

[0070] When it is necessary to adjust the area of ​​the area under the sunshade 1, the user pushes the lower drive member 42, which moves upward. The movable rod 55 and the movable plate 52 are in a contracted state, that is, the distance between the connecting block 53 and the movable plate 52 decreases. At this time, the first spring 57 is in a compressed state, and the connecting plate 51 and the connecting rod 54 are in an extended state, that is, the distance between the connecting plate 51 and the connecting block 53 increases. At this time, the second spring 59 is in a decompressed state. The elastic force provided by the second spring 59 increases the distance between the connecting plate 51 and the connecting block 53 and provides a pushing force for the displacement of the movable support plate 202, thereby causing the movable support plate 202 to move outward relatively parallel to the surface of the rotating support plate 201, thereby increasing the area of ​​the area under the sunshade 1. Similarly, when it is necessary to reduce the area of ​​the area under the sunshade 1, the lower drive member 42 is pushed downward.

[0071] When the shape of the sunshade 1 needs to be changed, i.e., when the sunshade is located on the car window and the car window is rectangular with a shorter top and a longer bottom, the user moves the lower drive member 42 upward to increase the area of ​​the lower region of the sunshade 1. At the same time, the distance between the ends of the two movable support plates 202 in the lower region of the sunshade 1 will increase, thereby increasing the lateral distance of the lower region of the sunshade 1. Simultaneously, the upper drive member 41 moves downward to decrease the area of ​​the upper region of the sunshade 1. At the same time, the distance between the ends of the two movable support plates 202 in the upper region of the sunshade 1 will decrease, thereby decreasing the lateral distance of the upper region of the sunshade 1. Then, through the left and right swinging of the connecting component 5 and the hinge component 6 with the rectangular sleeve 8, the drive device 4 and the bracket 2, the angle between the two adjacent brackets 2 is adjusted, so that the sunshade 1 fits the car window better.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
