Description

Technical Field

[0001] This invention relates to the field of vehicle structure technology, and more specifically, to a sunshade device, a vehicle, and a sunshade control method. Background Technology

[0002] Currently, cars have various windshields around them. For example, in the conventional design of cars, the front and rear windows occupy a relatively large area, thus giving the driver a better view and making driving easier.

[0003] In current vehicle usage scenarios, there is a need to park cars in open-air parking lots, especially in many older locations without underground parking, leaving only open-air parking. In summer or during periods of strong sunlight, sunlight shines through the car windows, causing the interior temperature to become very high, making the car uncomfortable to drive again. Current car windows typically lack automatic sunshades; the existing solution usually involves placing a sunshade inside the car, which the driver manually unfolds and places on the windshield or rear window after parking. However, this requires manual operation and is inconvenient.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The purpose of this invention is to provide a sunshade device, a vehicle, and a sunshade control method, which solves the problem that vehicles in the prior art cannot automatically provide sunshade.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: On one hand, the present invention provides a sunshade device, comprising: Flexible light-shielding component, which has a movable end; The synchronous winding and unwinding structures are located on both sides of the width direction. The synchronous winding and unwinding structures include: winding and unwinding components and traction lines. The take-up and unwind assembly has a rotating turntable, with both ends of the traction line wound and connected to the turntable respectively, and the winding directions of the two ends of the traction line are opposite. The movable end of the flexible light-blocking member is connected to the traction line. as well as The sensing control component is electrically connected to the take-up and unwinding assembly. The sensing control component is used to sense the environmental status information of the vehicle and control the take-up and unwinding assembly according to the environmental status information. The traction line drives the flexible light-shielding component to have a first state, a second state, and a third state through the rotation of the turntable; in the first state, the flexible light-shielding component is fully unfolded in the length direction to block the vehicle window glass; in the second state, the flexible light-shielding component is partially unfolded in the length direction to partially block the vehicle window glass; in the third state, the flexible light-shielding component is folded in the length direction to be housed in the vehicle body.

[0007] In an optional embodiment, limit blocks, multiple driven sliders, and active sliders are respectively provided at intervals on both sides of the width direction of the flexible light-shielding member. The active slider is located at the movable end and is connected to the traction line; The limiting block is connected to the end of the flexible light-shielding component opposite to the movable end; Multiple driven sliders are located between the active slider and the limit block, and the traction line runs through the limit block and the multiple driven sliders.

[0008] In an optional embodiment, the synchronous winding and unwinding structure further includes a guide portion, which is disposed at the edge of the vehicle body's window glass in the width direction. Multiple driven and driving sliders are slidably mounted on the guide section.

[0009] In one optional embodiment, the flexible light-shielding member has a top section, a middle section and a tail section in sequence along its length. The spacing between the driven sliders in the top section is smaller than the spacing between the driven sliders in the middle section.

[0010] In an optional embodiment, the spacing between the driven sliders in the tail section is smaller than the spacing between the driven sliders in the middle section.

[0011] In an optional embodiment, the traction line includes: a first pull line and a second pull line, with one end of the first pull line and one end of the second pull line respectively connected to the movable end; The synchronous winding and unwinding structure also includes: at least one pulley, which is rotatably mounted inside the vehicle body, and a first pull cable is sleeved on the pulley and changes direction through the pulley.

[0012] In an optional embodiment, the take-up and unwind assembly further includes a drive motor, with a turntable connected to the drive motor; The turntable is provided with a first winding groove and a second winding groove. The first winding groove is used to wind up one end of the traction wire, and the second winding groove is used to wind up the other end of the traction wire.

[0013] In an optional embodiment, the sensing control component includes: a controller electrically connected to the synchronous take-up and untake-up structure; Vehicle speed sensor, which is electrically connected to the controller, is used to detect vehicle speed in environmental status information; A temperature sensor, electrically connected to the controller, is used to detect the vehicle interior temperature from environmental status information. A light sensor, electrically connected to a controller, is used to detect the external light intensity in the environmental status information. The controller controls the synchronous winding and unwinding structure based on vehicle speed, interior temperature, and exterior light intensity.

[0014] On the other hand, this application also proposes a vehicle, including a vehicle body and the sunshade device as described above.

[0015] Thirdly, this application also proposes a shading control method, wherein the shading device described above is used, and the shading control method includes the following steps: The system detects when the sunshade mode is activated and acquires environmental status information about the vehicle, including vehicle speed, interior temperature, and exterior light intensity. Based on the comparison between environmental status information and preset thresholds, the winding and unwinding assembly is controlled to drive the flexible light-shielding component. Among them, when the vehicle speed is equal to 0, the interior temperature is greater than the preset interior temperature and the external light intensity is greater than the preset light intensity, the flexible light shield is in the first state. When the vehicle speed is greater than 0, the external light intensity is greater than the preset light intensity, causing the flexible light shield to be in the second state. When the vehicle speed is greater than 0 and the external light intensity is less than the preset light intensity, the flexible light shield is in the third state.

[0016] The beneficial effects of the sunshade device, vehicle, and sunshade control method provided by this invention are at least as follows: The sensor control component senses the environmental state information of the vehicle and determines whether to control the synchronous winding structure based on this information. This causes the winding component of the synchronous winding structure to drive the traction line, which in turn causes the flexible sunshade to unfold and retract. The flexible sunshade has three states under the influence of the synchronous winding structure: a first state, a second state, and a third state. In the first state, the flexible sunshade is fully unfolded along its length to block the vehicle's windows. When the vehicle is parked outdoors and the sunlight is strong, the flexible sunshade fully unfolds to block the entire window, preventing sunlight from entering the vehicle. In the second state, the flexible sunshade is partially unfolded along its length to partially block the vehicle's windows. In this state, when the vehicle is in motion and the sunlight intensity is high, the flexible sunshade partially unfolds, providing partial light blocking without obstructing the driver's view. In the third state, the flexible sunshade is folded along its length and housed within the vehicle body. In this state, when the light intensity is low while the vehicle is in motion, the flexible sunshade is completely folded and housed within the vehicle body, without obstructing the windows. By incorporating this sunshade device within the vehicle body, the vehicle gains an automatic sunshade function. The vehicle automatically applies sunshade based on current environmental conditions, improving the convenience of using the vehicle after parking in the open and further enhancing the vehicle's automation level.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0022] Example 1 Please see Figure 1 This embodiment proposes a sunshade device that can be installed on various windows of a vehicle as needed. For ease of structural description, the structure is illustrated by example of installing the sunshade device on the front or rear window of the vehicle. By installing the sunshade device on the front and rear windows, effective sun shading can be provided when the vehicle is parked outdoors. All structures in this sunshade device are described with the standard orientation of the vehicle body as a reference, such as... Figure 3As shown, the front-rear direction of the vehicle body is the same as the front-rear direction described in the structural design of this scheme, such as... Figure 1 As shown, the left-right direction of the vehicle body is the width direction in this structural description, and the up-down direction of the vehicle body is the length direction in this structural description.

[0023] Please see Figure 1 , Figure 2 , Figure 7 The sunshade device of this embodiment mainly includes: a flexible sunshade 100, at least two synchronously retractable structures 200, and a sensing control component 300. The flexible sunshade 100 is mainly used to block sunlight from entering the vehicle interior through the windshield. Therefore, the flexible sunshade 100 can be made of sun-blocking fabric, and a reflective layer is provided on the front surface of the flexible sunshade 100 to reflect sunlight, thus minimizing sunlight entering the vehicle interior. The flexible sunshade 100 has a fixed end 102 and a movable end 101, typically with the fixed end 102 being the upper end and the movable end 101 the lower end. Moving the movable end 101 upwards allows the flexible sunshade 100 to retract, allowing it to be retracted when sun protection is not needed; moving the movable end 101 downwards allows the flexible sunshade 100 to unfold, enabling it to block sunlight from entering the windshield when needed. Two synchronous roll-up and roll-down structures 200 are located on both sides of the width direction. These structures can synchronously control the left and right sides of the flexible light-shielding member 100 at the edges of the vehicle window, ensuring stable expansion and contraction of the member. A sensing control component 300 is electrically connected to the roll-up and roll-down assembly 210 and is used to sense the environmental conditions of the vehicle. It compares the detected environmental conditions with a preset threshold to determine whether the vehicle needs light shading and, if so, to what extent.

[0024] Please see Figure 1 , Figure 2The synchronous winding and unwinding structure 200 in this embodiment mainly includes: a winding and unwinding assembly 210 and a traction line 220. The winding and unwinding assembly 210 has a rotatable turntable 211, and the two ends of the traction line 220 are respectively wound and connected to the turntable 211, and the winding directions of the two ends of the traction line 220 are opposite. The movable end 101 of the flexible light-shielding member 100 is connected to the traction line 220. In the specific structure, the traction wire 220 is wound around and both ends are connected to the turntable 211. The turntable 211 is provided with two winding grooves. The two ends of the traction wire 220 are wound or unwound in the two winding grooves respectively. When the turntable 211 rotates, one end of the traction wire 220 is wound up and the other end is unwound. In this way, after the traction wire 220 is connected to the movable end 101 of the flexible light-blocking component 100, the upper end of the traction wire 220 is wound up and the lower end is unwound. The connection position between the traction wire 220 and the movable end 101 is moved upward as a whole, so that the soft light-blocking component can be pulled upward and wound up. Similarly, the turntable 211 rotates in the opposite direction to realize the unfolding of the soft light-blocking component. The traction wire 220 drives the flexible light-blocking component 100 to have a first state, a second state, and a third state through the rotation of the turntable 211. According to the comparison result of the environmental state information and the preset threshold, the flexible light-blocking component 100 is automatically controlled to be in different states to realize the automatic light-blocking function. In the first state, the flexible light-shielding member 100 is fully extended in the length direction to block the vehicle window glass; in the second state, the flexible light-shielding member 100 is partially extended in the length direction to partially block the vehicle window glass; in the third state, the flexible light-shielding member 100 is folded in the length direction to be housed in the vehicle body.

[0025] Please see Figure 1 , Figure 7The working principle of the sunshade device provided in this embodiment is as follows: The sensing control component 300 senses the environmental state information of the vehicle and determines whether to control the synchronous winding and unwinding structure 200 based on the environmental state information. This causes the winding and unwinding component 210 of the synchronous winding and unwinding structure 200 to drive the traction line 220. During the rotation of the turntable 211, one end of the traction line 220 winds up while the other end unwinds, thereby driving the movable end 101 of the flexible sunshade 100 to move up and down. The movement of the traction line 220 causes the flexible sunshade 100 to unfold and retract, resulting in different unfolded or retracted states after the flexible sunshade 100 is activated. In the first state, the flexible sunshade 100 is fully unfolded along its length to block the vehicle's window glass. Thus, when the vehicle is parked outdoors and the sunlight is strong, the flexible sunshade 100 fully unfolds to block the entire window glass, preventing sunlight from entering the vehicle. In the second state, the flexible sunshade 100 is partially unfolded along its length to partially block the vehicle's windows. In this state, when the light intensity is high while the vehicle is in motion, the flexible sunshade 100 partially unfolds, providing partial light blocking without obstructing the driver's view. In the third state, the flexible sunshade 100 is folded along its length and housed within the vehicle body. In this state, when the light intensity is low while the vehicle is in motion, the flexible sunshade 100 is completely folded and housed within the vehicle body, without blocking the windows. Thus, by incorporating this sunshade device within the vehicle body, the vehicle gains an automatic sunshade function. The vehicle automatically opens or closes the sunshade based on current environmental conditions. After parking outdoors, the automatically opened sunshade can block sunlight after the driver leaves the vehicle, effectively improving the high temperature inside the vehicle when the driver re-enters, increasing the convenience of using the vehicle after outdoor parking, and further enhancing the vehicle's automation level.

[0026] Please see Figure 2 , Figure 4 , Figure 5Furthermore, in this embodiment, the flexible light-shielding member 100 has limit blocks 110, multiple driven sliders 120, and active sliders 130 spaced apart on both sides of its width direction. Limit blocks 110, multiple driven sliders 120, and active sliders 130 are provided on both sides of the flexible light-shielding member 100. The limit block 110 is fixedly disposed at the fixed end 102 (upper end) of the flexible light-shielding member 100, and the limit block 110 can also be fixedly disposed within the vehicle body. The active slider 130 is located at the movable end 101 and is fixedly connected to the traction line 220; multiple driven sliders 120 are located between the active slider 130 and the limit block 110, and the traction line 220 passes through the limit block 110 and the multiple driven sliders 120. In the specific structure, a through hole is provided between the limiting block 110 and the multiple driven sliders 120. After the traction wire 220 is fixed to the driving slider 130, one end passes through the through hole sequentially upward through the multiple driven sliders 120 and finally exits from the limiting block 110. This means that the traction wire 220 is not fixedly connected to the limiting block 110 or the multiple driven sliders 120. Therefore, the movement of the traction wire 220 only drives the driving slider 130 to move. Thus, when it is necessary to unfold the flexible light-shielding member 100, the driving slider 130 is pulled downward by the traction wire 220. Since both the driving slider 130 and the driven sliders 120 are connected to the flexible light-shielding member 100, the pulling action of the flexible light-shielding member 100 causes the multiple driven sliders 120 to be pulled sequentially, thereby unfolding the flexible light-shielding member 100. When the flexible sunshade 100 needs to be retracted, the active slider 130 is pulled upward by the traction line 220. The active slider 130 will abut against the driven slider 120. As the active slider 130 continues to move upward, multiple driven sliders 120 will abut against each other from bottom to top. Under the push of the active slider 130, they will move to the position above the windshield. Therefore, through the pushing action of the active slider 130, the driven sliders 120 are pulled back into the vehicle body above the windshield, thereby retracting the flexible sunshade 100. By using multiple driven sliders 120 and limiting blocks 110, the flexible sunshade 100 can be smoothly retracted and extended. In particular, when the flexible sunshade 100 is made of sun-blocking cloth, it can provide stable support for the sun-blocking cloth on both sides, realizing the function of gradually unfolding and retracting the sun-blocking cloth.

[0027] Please see Figure 3 , Figure 4 , Figure 6Furthermore, the synchronous winding and unwinding structure 200 also includes a guide section 400, which is used to be set at the edge of the vehicle window glass in the width direction. The guide section 400 can be a steel structure guide frame, and the shape of the guide section 400 can match the shape of the vehicle's A-pillar, so that it can be set on the A-pillars on the left and right sides of the front window glass. A guide groove 410 is provided in the steel structure guide frame, and the extension direction of the guide groove 410 matches the edge contour of the left and right sides of the front window glass. Multiple driven sliders 120 and active sliders 130 are slidably set on the guide section 400, so that the driven sliders 120 and active sliders 130 can move smoothly and stably on both sides of the front window glass, and the flexible light shield 100 can cover the entire front window glass relatively perfectly.

[0028] Since the guide section 400 needs to match the A-pillar of the vehicle body, and the existing vehicle body contour is usually curved, the guide section 400 also needs to have an arc or curved section. In order to facilitate the turning of multiple driven sliders 120 and active sliders 130 in the guide groove 410, in this embodiment, multiple driven sliders 120 and active sliders 130 are all provided with spherical shape, which facilitates a smooth transition when sliding in the arc or curved section.

[0029] Please see Figure 1 , Figure 4 , Figure 5 Furthermore, in this embodiment, the flexible light-shielding member 100, when unfolded, has a top section 140, a middle section 150, and a tail section 160 sequentially along its length. Multiple driven sliders 120 are provided on the left and right edges of each section. The spacing between the driven sliders 120 in the top section 140 is smaller than the spacing between the driven sliders 120 in the middle section 150. Therefore, the density of the driven sliders 120 in the top section 140 is greater than that in the middle section 150. Because existing vehicles have an arc-shaped transition section above the windshield that connects to the roof, there is a certain arc-shaped transition area above the windshield. When the flexible light shield 100 is fully extended, if the spacing of the driven sliders 120 is the same, the middle section 150 can cover the windshield relatively well. However, the top section 140 will be spaced further away from the windshield, creating a large gap and posing a significant risk of light leakage. Therefore, the driven sliders 120 of the top section 140 are arranged more densely, which can be densely distributed in the arc-shaped transition section. This way, the fully extended flexible light shield 100 has more support points in the top section 140, allowing the extended outline of the top section 140 of the flexible light shield 100 to better match the upper part of the windshield, thereby achieving better coverage.

[0030] Furthermore, the spacing between the driven sliders 120 within the tail section 160 is smaller than the spacing between the driven sliders 120 within the middle section 150. When the flexible light-shielding member 100 is in the second state, only the tail section 160 is deployed. The function of the tail section 160 is equivalent to that of the top section 140 when fully deployed. Therefore, the driven sliders 120 of the tail section 160 are arranged more densely, so that the partially deployed flexible light-shielding member 100 has more support points in the tail section 160, allowing the deployment contour of the tail section 160 of the flexible light-shielding member 100 to better match the upper end of the windshield, thereby achieving better coverage.

[0031] Please see Figure 2 , Figure 4 Furthermore, the traction line 220 includes a first pull line 221 and a second pull line 222. The active slider 130 can be a movable end 101 (the two are fixedly connected), and connecting rings are respectively provided on the upper and lower ends of the active slider 130. One end of the first pull line 221 and one end of the second pull line 222 are respectively connected to the connecting rings in the upper and lower directions of the active slider 130. The synchronous winding and unwinding structure 200 also includes at least one pulley 230, which is rotatably mounted in the vehicle body. The first pull line 221 is sleeved on the pulley 230 and changes direction through the pulley 230. In the specific structure, the roll-up assembly 210 is located in the vehicle body below the windshield. This location on the vehicle body is where the steering wheel, instrument panel, etc., are installed, providing sufficient space for the roll-up assembly 210. The pulley 230 is located on the roof. The first pull cable 221 passes upward through each driven slider 120 and the limiting slider, then loops onto the pulley 230, and extends downward to connect to the turntable 211 of the roll-up assembly 210 below. The second pull cable can be directly wound around the turntable 211, or it can also pass through the pulley 230 below and then connect to the turntable 211. This structure allows the relatively large roll-up assembly 210 to be placed at the bottom, optimizing the structure and reasonably adapting to the common design of existing vehicles, making this sunshade device more practical.

[0032] Please see Figure 2 Furthermore, the winding and unwinding assembly 210 in this embodiment also includes a drive motor 214. A turntable 211 is connected to the drive motor 214. The turntable 211 is provided with a first winding groove 212 and a second winding groove 213. The first winding groove 212 is used to wind up one end of the traction wire 220, and the second winding groove 213 is used to wind up the other end of the traction wire 220. The drive motor 214 in this embodiment can be a stepper motor or a servo motor. By driving the turntable 211 with the drive motor 214, automatic control is easily achieved. When the first winding groove 212 winds up the traction wire 220, the second winding groove 213 unwinds the traction wire 220.

[0033] Please see Figure 6 , Figure 7 To detect the state of the flexible light-shielding component 100, a detection component 500 is provided on the guide portion 400 and the active slider 130. For example, a detection boss 510 is provided on the active slider 130, and photoelectric sensors 520 are provided at three positions on the guide portion 400 to sense whether the detection boss 510 is in place, thereby determining whether the active slider 130 has reached the preset position.

[0034] Please see Figure 7 Furthermore, the sensing control component 300 specifically includes: a controller 310, a vehicle speed sensor 320, a temperature sensor 330, and a light sensor 340. The controller 310 is electrically connected to the synchronous winding and unwinding structure 200. The vehicle speed sensor 320 is electrically connected to the controller 310 and is used to detect the vehicle speed in the environmental status information. The temperature sensor 330 is electrically connected to the controller 310 and is used to detect the vehicle interior temperature in the environmental status information. The light sensor 340 is electrically connected to the controller 310 and is used to detect the external light intensity in the environmental status information. A sunshade mode is set in the vehicle's control mode. If the sunshade mode is set, even when the vehicle is parked, the controller 310 can control the vehicle speed sensor 320, temperature sensor 330, and light sensor 340 to be in working condition. The controller 310 controls the synchronous winding and unwinding structure 200 based on the vehicle speed, vehicle interior temperature, and external light intensity. The specific control process is as follows: When the vehicle speed is 0, the interior temperature is higher than the preset interior temperature, and the external light intensity is higher than the preset light intensity, the flexible sunshade 100 is in its first state. This scenario indicates the vehicle is parked. If the vehicle is parked outdoors, it is necessary to detect the interior temperature and external light intensity. If the external light intensity is high, and the parking time is long, the interior temperature will rise, triggering the sunshade device to activate. Furthermore, the flexible sunshade 100 will completely block the windshield, preventing the interior temperature from rising further due to sunlight.

[0035] When the vehicle speed is greater than 0 and the external light intensity is greater than the preset light intensity, the flexible sunshade 100 is in its second state. In this scenario, it indicates that the vehicle is in motion and the external light intensity needs to be detected. If the external light intensity is high, the strong light will interfere with the driver, thereby triggering the sunshade device to activate and causing the flexible sunshade 100 to partially block the windshield, making it easier for the driver to drive.

[0036] When the vehicle speed is greater than 0 and the external light intensity is less than the preset light intensity, the flexible sunshade 100 is in the third state. In this scenario, it means that the vehicle is moving and the external light intensity needs to be detected. If the external light intensity is low, the strong light will not interfere with the driver, thus triggering the sunshade to close. If the flexible sunshade 100 partially blocks the windshield, it can be completely retracted. If the flexible sunshade 100 is already in the fully retracted state, the turntable 211 does not need to be rotated.

[0037] Example 2 This embodiment proposes a vehicle, including a vehicle body and a sunshade device as described above. The sunshade device is disposed on the inside of the window glass of the vehicle body, and can block the inside of the window glass to block light.

[0038] Example 3 This embodiment proposes a shading control method for the shading device described in Embodiment 1 above, comprising the following steps: Step S100: Detect that the sunshade mode is turned on and obtain the environmental status information of the vehicle body, including: vehicle speed, vehicle interior temperature and external light intensity.

[0039] Step S200: Based on the comparison result between the environmental status information and the preset threshold, control the winding and unwinding assembly to drive the flexible light-shielding component.

[0040] In the specific steps: When the vehicle speed is 0, the interior temperature is higher than the preset interior temperature, and the external light intensity is higher than the preset light intensity, the flexible sunshade is in its first state. This scenario indicates the vehicle is parked. If the vehicle is parked outdoors, it needs to detect the interior temperature and external light intensity. If the external light intensity is high, and the parking time is long, the interior temperature rises, triggering the sunshade device to activate and completely block the windshield with the flexible sunshade to prevent the interior temperature from rising further due to sunlight. It can also automatically control the air conditioner to turn on, lowering the interior temperature. When the temperature drops to a preset comfortable level, the air conditioner turns off, ensuring a comfortable environment when the vehicle is used again. When the vehicle starts, the controller retracts the flexible sunshade, allowing the vehicle to be used normally.

[0041] When the vehicle speed is greater than 0 and the external light intensity is greater than the preset light intensity, the flexible sunshade is in its second state. In this scenario, it indicates that the vehicle is in motion and the external light intensity needs to be detected. If the external light intensity is high, the strong light will interfere with the driver, thus triggering the sunshade device to activate and causing the flexible sunshade to partially block the windshield, making it easier for the driver to drive.

[0042] When the vehicle speed is greater than 0 and the external light intensity is less than the preset light intensity, the flexible sunshade is in its third state. In this scenario, it indicates that the vehicle is in motion and the external light intensity needs to be detected. If the external light intensity is low, the strong light will not interfere with the driver, thus triggering the sunshade to close. If the flexible sunshade partially blocks the windshield, it can be fully retracted. If the flexible sunshade is already fully retracted, the turntable does not need to be controlled.

[0043] In summary, this application proposes a sunshade device, a vehicle, and a sunshade control method. A sensing control component detects the environmental conditions of the vehicle and controls the expansion and contraction of a flexible sunshade based on this information. The flexible sunshade can be in a first state, fully expanded along its length to block the vehicle's windows. When the vehicle is parked outdoors and sunlight is strong, the flexible sunshade fully expands to block the entire window, preventing sunlight from entering the vehicle. Alternatively, the flexible sunshade can be in a second state, partially expanded along its length to partially block the vehicle's windows. In this case, when the vehicle is in motion and sunlight intensity is high, the flexible sunshade partially expands, providing partial shading without obstructing the driver's view. Alternatively, the flexible sunshade can be in a third state, folded along its length to be housed within the vehicle body. In this case, when the vehicle is in motion and sunlight intensity is low, the flexible sunshade fully folds and is housed within the vehicle body, without blocking the windows. By installing this sunshade device inside the vehicle, the vehicle gains an automatic sunshade function. The vehicle automatically opens or closes the sunshade based on the current environmental conditions. After parking in the open, the automatically opened sunshade can block sunlight after the driver leaves the vehicle, effectively improving the high temperature inside the vehicle when the driver re-enters, increasing the convenience of using the vehicle after parking in the open, and further enhancing the vehicle's automation level.
