[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] Reference below Figure 1-Figure 4 The sunshade device 100, the vehicle, and the control method of the sunshade device 100 according to the embodiment of the present invention are described.

[0048] According to the sunshade device 100 of the first embodiment of the present invention, Figure 1-Figure 4 , including: a sun visor 10 and a dressing mirror 50.

[0049] The sun visor 10 includes a first plate body 21, a second plate body 22 and an adjustment layer 23. The light transmittance of the adjustment layer 23 is adjustable and is located between the first plate body 21 and the second plate body 22. The first plate body 21 and the second plate body 22 are both light-transmitting parts. By making the light transmittance of the adjustment layer 23 adjustable, the adjustment layer 23 can adjustably filter sunlight to meet the needs of different users for different sunlight environments; and the adjustment layer 23 has a certain light transmittance, so that the user can see the road conditions outside through the adjustment layer 23, avoiding the adjustment layer 23 from blocking the line of sight, while the visual effect is comfortable and the sunlight is avoided directly into the eyes, the user's field of vision when using the sun visor 10 is expanded, and driving safety is improved. By making the sun visor 10 include the first plate body 21 and the second plate body 22, and the first plate body 21 and the second plate body 22 are both light-transmitting parts, the first plate body 21 and the second plate body 22 can have a lower influence on the overall light transmittance of the sun visor 10; and the adjustment layer 23 can be protected to avoid scratches and damage to the adjustment layer 23.

[0050] In some embodiments of the present invention, the first plate 21 and the second plate 22 are preferably transparent parts, so as to better prevent the sun visor 10 from blocking the line of sight. In other embodiments, the first plate 21 and the second plate 22 may also be of a specific color for filtering light, so as to filter light according to design requirements.

[0051] For example, when there is sufficient sunlight outside the vehicle and the sunlight shines directly into the eyes, the transmittance of the adjustment layer 23 can be reduced to improve the user's visual comfort and avoid danger caused by excessive sunlight shining directly into the eyes. In addition, since the adjustment layer 23 is translucent, the first plate 21 and the second plate 22 are both translucent parts, the user can see the external environment through the sunshade device 100, thereby improving driving safety.

[0052] For example, when the intensity of sunlight outside the vehicle is weak or the angle of sunlight is not directly into the eyes, the transmittance of the adjustment layer 23 can be increased, so that the user can see the external environment more clearly through the sunshade device 100, thereby improving driving safety.

[0053] The sun visor 10 includes a first area 24 and a second area 25, the adjustment layer 23 includes a first adjustment layer 26 provided in the first area 24 and a second adjustment layer 28 provided in the second area 25, the vanity mirror 50 is provided in the first area 24, and the vanity mirror 50 has light transmittance and light reflectivity, and the light transmittance and light reflectivity of the vanity mirror 50 are both related to the light transmittance of the first adjustment layer 26. When the light transmittance of the first adjustment layer 26 is greater than or equal to the first transparency threshold, the vanity mirror 50 has light transmittance; when the light transmittance of the first adjustment layer 26 is less than the first transparency threshold, the vanity mirror 50 has light reflectivity. For example, the first transparency threshold may be 60%. By controlling the first adjustment layer 26 and the second adjustment layer 28, the sunshade function and the vanity mirror function can be made independent of each other and have no influence on each other, and the functional distinction is more obvious.

[0054] Specifically, the first adjustment layer 26 and the second adjustment layer 28 can be independently controlled by two controllers, and the independent control is more efficient; they can also be controlled by a centralized controller by transmitting different control signals to reduce control costs. The dressing mirror 50 is a high-transmittance and high-reflection mirror. When the transmittance of the first adjustment layer 26 is greater than or equal to the first transparency threshold, the dressing mirror 50 has light transmittance and realizes the function of light transmittance; when the transmittance of the first adjustment layer 26 is less than the first transparency threshold, the dressing mirror 50 has light reflectivity and realizes the function of a mirror.

[0055] For example, when the light transmittance of the first adjustment layer 26 is increased, the dressing mirror 50 has light transmittance; when the light transmittance of the first adjustment layer 26 is decreased, the dressing mirror 50 has light reflectivity.

[0056] For example, the user can enable the sunshade device 100 to turn on the dressing function, and the transmittance of the first adjustment layer 26 will be reduced. At this time, the dressing mirror 50 will be reflective. At the same time, the transmittance of the second adjustment layer 28 can be adjusted independently to prevent the user from being directly exposed to the sun while seeing the external environment more clearly.

[0057] According to the sunshade device 100 of the embodiment of the present invention, by making the sunshade device 100 include an adjustment layer 23 with adjustable transmittance, the sunshade device 100 can change its own transmittance, filter sunlight in an adjustable manner and avoid blocking the line of sight, so that the user's visual effect is comfortable, the user's field of vision when using the sun visor 10 is expanded, and driving safety is improved; and, by controlling the first adjustment layer 26 and the second adjustment layer 28, the sunshade function and the makeup mirror function can be made independent of each other and do not affect each other, the functional distinction is more obvious, and the sunshade function and the makeup function can be better exerted and used.

[0058] According to some embodiments of the present invention, referring to Figure 1 When the sunshade device 100 turns off the dressing function, the dressing mirror 50 is light-transmissive; when the sunshade device 100 turns on the dressing function, the dressing mirror 50 is reflective; the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function is less than the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function. By making the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function less than the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function, when the sunshade device 100 turns on the dressing function, the light transmittance of the first adjustment layer 26 can be lower, and the dressing mirror 50 can be reflective, thereby presenting the function of a mirror; when the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 can be higher, and the dressing mirror 50 can be light-transmissive to avoid blocking the line of sight.

[0059] According to some embodiments of the present invention, referring to Figure 1 When the sunshade device 100 turns off the dressing function, the assembly formed by the first adjustment layer 26 and the dressing mirror 50 is used to adjust the light intensity after passing through the sun visor 10 to less than or equal to the first light intensity threshold; the second adjustment layer 28 is used to adjust the light intensity after passing through the sun visor 10 to less than or equal to the second light intensity threshold. For example, the first light intensity threshold and the second light intensity threshold are both less than or equal to 40cd, for example, the first light intensity threshold can be in the range of 30cd to 40cd, and the second light intensity threshold can be in the range of 30cd to 40cd. When the light intensity outside the car is high, the light outside the car enters the car, and after being filtered by the sun visor 10, the light intensity can be reduced, so that the light intensity entering the human eye is low, thereby improving the visual comfort of the user, avoiding the danger caused by excessively strong sunlight directly entering the eye, and the user can see the external environment more clearly through the sunshade device 100, thereby improving the safety of driving.

[0060] Among them, light intensity refers to the luminous intensity, that is, the luminous flux emitted by a light source in a specific direction. Its unit is candela, abbreviated as candela, with the symbol cd.

[0061] In some embodiments of the present invention, when the sunshade device 100 turns off the dressing function, the first adjustment layer 26 can adjust the light transmittance in real time according to the light intensity, that is, when the light intensity increases, the light transmittance of the first adjustment layer 26 decreases, thereby blocking more strong light; when the light intensity decreases, the light transmittance of the first adjustment layer 26 increases, thereby enabling the user's field of vision to be clearer. The second adjustment layer 28 can adjust the light transmittance in real time according to the light intensity, that is, when the light intensity increases, the light transmittance of the second adjustment layer 28 decreases, thereby blocking more strong light; when the light intensity decreases, the light transmittance of the second adjustment layer 28 increases, thereby enabling the user's field of vision to be clearer. By adjusting the light transmittance of the first adjustment layer 26 and the second adjustment layer 28 in real time, light can be provided in real time according to the light intensity and in accordance with the needs of the user.

[0062] In other embodiments of the present invention, when the sunshade device 100 turns off the dressing function, the first adjustment layer 26 does not need to adjust the transmittance in real time according to the light intensity, but sets two states of sunshade and light transmission. When the light intensity is greater than the external light intensity threshold, such as 60cd, the first adjustment layer 26 plays a role in blocking sunlight, and the transmittance of the first adjustment layer 26 is adjusted to the first transmittance, such as 20% transmittance; when the light intensity is less than the external light intensity threshold, such as 60cd, the first adjustment layer 26 plays a role in enhancing the field of vision, and the transmittance of the first adjustment layer 26 is adjusted to the second transmittance, such as 60% transmittance, and the second transmittance is greater than the first transmittance. The second adjustment layer 28 does not need to adjust the transmittance in real time according to the light intensity, but sets two states of sunshade and light transmission. When the light intensity is greater than the external light intensity threshold, such as 60cd, the second adjustment layer 26 plays a role in shielding sunlight, and the transmittance of the second adjustment layer 28 is adjusted to the third transmittance, such as 20% transmittance; when the light intensity is less than the external light intensity threshold, such as 60cd, the second adjustment layer 28 plays a role in enhancing the field of vision, and the transmittance of the second adjustment layer 28 is adjusted to the fourth transmittance, such as 60% transmittance, and the fourth transmittance is greater than the third transmittance. By adjusting the transmittance of the first adjustment layer 26 to the first transmittance or the second transmittance according to the light intensity, the first adjustment layer 26 can block sunlight or enhance the field of vision, and can also save costs; by adjusting the transmittance of the second adjustment layer 28 to the third transmittance or the fourth transmittance according to the light intensity, the second adjustment layer 28 can block sunlight or enhance the field of vision, and can also save costs.

[0063] According to some embodiments of the present invention, referring to Figure 1When the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 is greater than the light transmittance of the second adjustment layer 28. Since the first adjustment layer 26 is overlapped with the dressing mirror 50, the light passing through the first adjustment layer 26 enters the human eye through the dressing mirror 50, so that the overall light transmittance of the first area 24 is reduced. By making the light transmittance of the first adjustment layer 26 greater than the light transmittance of the second adjustment layer 28, it is possible to avoid a large difference in brightness when the light passing through the first area 24 and the second area 25 enters the human eye, and reduce the difference in light intensity passing through the first area 24 and the second area 25.

[0064] According to some embodiments of the present invention, referring to Figure 1 , the absolute value of the difference between the first light intensity threshold and the second light intensity threshold is less than 5 cd, for example, the difference between the first light intensity threshold and the second light intensity threshold can be 0. For example, the light transmittance of the assembly formed by the first adjustment layer 26 and the vanity mirror 50 in the first sunshade state can be the same as the light transmittance of the second adjustment layer 28 in the second sunshade state. By making the absolute value of the difference between the first light intensity threshold and the second light intensity threshold less than 5 cd, the light intensity through the first area 24 and the second area 25 can be made substantially the same, so that when the user uses it, the brightness of the outside world seen by the user through the first area 24 and the second area 25 is substantially the same, thereby improving the user's visual experience.

[0065] According to some embodiments of the present invention, referring to Figure 2 , the first plate 21 and the second plate 22 are both glass. By making the first plate 21 and the second plate 22 both glass, the light transmittance of the first plate 21 and the second plate 22 can be made higher, reducing the influence of the first plate 21 and the second plate 22 on the overall light transmittance of the sunshade device 100; and the cost can be reduced.

[0066] For example, the first plate body 21, the first adjustment layer 26 and the second plate body 22 are connected by transparent adhesive; the first plate body 21, the second adjustment layer 28 and the second plate body 22 are connected by transparent adhesive.

[0067] According to some embodiments of the present invention, the adjustment layer 23 is an electrochromic layer. By making the adjustment layer 23 an electrochromic layer, the light transmittance of the adjustment layer 23 can be changed by energizing the adjustment layer 23, making it more convenient for the user to change the light transmittance of the adjustment layer 23. For example, the light transmittance of the adjustment layer 23 can be changed relative to when it is not energized by energizing the adjustment layer 23. When the adjustment layer 23 is energized, the light transmittance of the adjustment layer 23 can be further adjusted by controlling the magnitude and / or direction of the current.

[0068] According to some embodiments of the present invention, the sunshade device 100 is installed on the roof decoration or the front windshield. When the light outside the vehicle enters the vehicle through the front windshield, the sunshade device 100 can effectively filter the light and reduce the intensity of the light. Specifically, the sunshade device 100 is installed on the roof decoration by fasteners, or is attached to the front windshield by bonding.

[0069] According to some embodiments of the present invention, referring to Figure 1 The sun visor 10 includes a sun visor body 20 and a mounting seat 30, the mounting seat 30 is used to connect with the vehicle body, the mounting seat 30 is connected to one end of the sun visor body 20, and the sun visor body 20 and the mounting seat 30 are detachably connected. By making the sun visor body 20 and the mounting seat 30 detachably connected, it is more convenient for relevant personnel to maintain or repair the sun visor body 20.

[0070] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the sun visor body 20 is connected to the mounting seat 30 by fasteners. By connecting the sun visor body 20 to the mounting seat 30 by fasteners, the connection between the sun visor body 20 and the mounting seat 30 can be made more secure, preventing the sun visor body 20 from falling off.

[0071] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The mounting seat 30 is provided with a clamping cavity 31, and one end of the sun visor body 20 is accommodated in the clamping cavity 31. By providing the clamping cavity 31 in the mounting seat 30 and accommodating one end of the sun visor body 20 in the clamping cavity 31, the contact area between the sun visor body 20 and the mounting seat 30 can be increased, and the connection is more secure.

[0072] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The mounting seat 30 includes a first cover plate 32 and a second cover plate 33 that are detachably connected, and the first cover plate 32 and the second cover plate 33 together define a clamping cavity 31. By making the mounting seat 30 include the first cover plate 32 and the second cover plate 33 that are detachably connected, and the first cover plate 32 and the second cover plate 33 together define the clamping cavity 31, the mounting seat 30 can be installed more easily.

[0073] For example, the second cover plate 33 is provided with a plurality of protrusions, and correspondingly, the sun visor body 20 is provided with a plurality of through holes. When the sun visor body 20 is installed on the second cover plate 33, the protrusions on the second cover plate 33 are respectively accommodated in the corresponding through holes, so that the second cover plate 33 can limit the sun visor body 20, making the connection between the second cover plate 33 and the sun visor body 20 more secure.

[0074] For example, the first cover plate 32 and the second cover plate 33 are connected by gluing.

[0075] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 The vanity mirror 50 is disposed adjacent to the mounting seat 30, and the mounting seat 30 is provided with a lighting panel 34, which includes a light guide plate 35 and a light strip 36, and the light strip 36 is located on the outer peripheral side of the light guide plate 35. By disposing the vanity mirror 50 adjacent to the mounting seat 30 and providing the lighting panel 34 on the mounting seat 30, the user can turn on the lighting panel 34 to increase the brightness in the cockpit, thereby making it more convenient to use the vanity mirror 50; by making the lighting panel 34 include the light guide plate 35 and the light strip 36, and the light strip 36 is located on the outer peripheral side of the light guide plate 35, the light guide plate 35 can make the light emitted by the light strip 36 more divergent, so that the lighting range of the lighting panel 34 is larger.

[0076] According to some embodiments of the present invention, referring to Figure 1 A first wiring channel 37 is provided in the mounting seat 30, and a control harness is arranged in the first wiring channel 37. The first adjustment layer 26 is connected to the first signal line connector 27, and the second adjustment layer 28 is connected to the second signal line connector 29. The first signal line connector 27 and the second signal line connector 29 are both located in the mounting seat 30 and connected to the control harness. By connecting the first adjustment layer 26 to the first signal line connector 27 and the second adjustment layer 28 to the second signal line connector 29, the first adjustment layer 26 and the second adjustment layer 28 can be controlled independently, so that the function of the sun visor 10 and the function of the makeup mirror are independent of each other and do not affect each other; by connecting the first signal line connector 27 and the second signal line connector 29 to the mounting seat 30 and connected to the control harness, the routing of the control harness can be more convenient, and the control harness can be prevented from being exposed to the outside.

[0077] According to some embodiments of the present invention, referring to Figure 1The sunshade device 100 further includes a fixing seat 40 and a rotating shaft 41. The fixing seat 40 is used to connect with the vehicle body and is arranged at one end of the rotating shaft 41. The rotating shaft 41 is rotatably connected to the mounting seat 30. A second wiring channel 42 communicating with the first wiring channel 37 is provided in the rotating shaft 41. The control harness is routed along the first wiring channel 37 and the second wiring channel 42. A signal line plug 43 is provided at the other end of the control harness. The signal line plug 43 is located on the side of the fixing seat 40 away from the sun visor 10. By making the fixing seat 40 connected with the vehicle body and arranged at one end of the rotating shaft 41, and the rotating shaft 41 is rotatably connected to the mounting seat 30, the sunshade device 100 can be rotated along the central axis of the rotating shaft 41 to meet different sunshade needs of users. For example, the sunshade device 100 can be rotated manually by the user or automatically by electric power; by making the second wiring channel 42 communicating with the first wiring channel 37 provided in the rotating shaft 41, the routing of the control harness can be made more convenient. By locating the signal line plug 43 on the side of the fixing base 40 away from the sun visor 10, it is convenient to connect the signal line plug 43 to other parts. For example, the vehicle includes a controller, and the signal plug is connected to the controller.

[0078] For example, a fixing hook 44 is also connected to the vehicle body, and the fixing hook 44 is arranged on the side of the sunshade device 100 away from the fixing seat 40 in the length direction. The rotating shaft 41 is hung on the fixing hook 44, which can make the fixation between the rotating shaft 41 and the vehicle body more reliable and prevent the sunshade device 100 from falling off.

[0079] The vehicle according to the second embodiment of the present invention comprises: a vehicle body, the sunshade device 100 according to the first embodiment of the present invention, a first light sensor, a second light sensor and a controller.

[0080] The first light sensor is installed on the vehicle body and is located outside the vehicle. The first light sensor is used to detect the light intensity and / or the direct angle of light outside the vehicle. The second light sensor is installed on the vehicle body and is located inside the vehicle. The second light sensor is used to detect the light intensity inside the vehicle. For example, the second sensor is used to detect the light intensity entering the human eye. The sunshade device 100, the first light sensor, and the second light sensor are all electrically connected to the controller. By using the first light sensor to detect the light intensity and / or the direct angle of light outside the vehicle, the second light sensor is used to detect the light intensity inside the vehicle, and the sunshade device 100, the first light sensor, and the second light sensor are all electrically connected to the controller, the controller can adjust the light transmittance of the sunshade device 100 according to the direct angle of light outside, the light intensity outside, and the light intensity inside the vehicle, so as to provide users with a more comfortable driving effect in different environments.

[0081] For example, the first light sensor is used to detect the light intensity outside the vehicle, and the second light sensor is used to detect the light intensity inside the vehicle. When the light intensity outside the vehicle is measured to be greater than that inside the vehicle, the controller controls the sunshade device 100 to rotate downward to start the sunshade device 100, and the controller controls the light transmittance of the sunshade device 100 to decrease; when the light intensity outside the vehicle is measured to be less than that inside the vehicle, the controller controls the sunshade device 100 to rotate upward to close the sunshade device 100.

[0082] For example, the first light sensor is used to detect the light intensity and direct light angle outside the vehicle. When it is detected that the direct light angle outside the vehicle reaches a set range and the outdoor light intensity reaches a set range, the controller controls the sunshade device 100 to rotate downward to start the sunshade device 100, and the controller controls the sunshade device 100 to reduce the light transmittance. The stronger the light intensity, the lower the light transmittance of the sunshade device 100, so that the user can obtain a more comfortable driving visual effect.

[0083] The vehicle according to the second embodiment of the present invention includes the sunshade device 100 according to the first embodiment of the present invention, which can filter sunlight in an adjustable manner and avoid blocking the line of sight, so that the user's visual effect is comfortable, the user's field of vision when using the sun visor 10 is expanded, and the driving safety is improved; by controlling the first adjustment layer 26 and the second adjustment layer 28, the sunshade function and the makeup mirror function can be made independent of each other and have no influence on each other, and the functional distinction is more obvious, so that the sunshade function and the makeup function can be better exerted and used.

[0084] According to a control method of a sunshade device 100 according to an embodiment of a third aspect of the present invention, the sunshade device 100 is a sunshade device 100 according to an embodiment of the second aspect of the present invention, and the control method of the sunshade device 100 includes:

[0085] According to the intensity of light outside the vehicle, the transmittance of the second adjustment layer 28 is adjusted to adjust the sunshade state of the second adjustment layer 28. Different transmittances of the second adjustment layer 28 result in different sunshade strengths. The lower the transmittance, the higher the sunshade strength. After the light outside the sunshade vehicle enters the vehicle and is filtered by the second adjustment layer 28, the light intensity is reduced to a suitable intensity to reduce the glare of external strong light, so that the user's visual effect is comfortable and the user's field of vision when using the sun visor is expanded;

[0086] According to whether the dressing function of the sunshade device 100 is turned on, the transmittance of the first adjustment layer 26 is adjusted to adjust the optical state of the dressing mirror. The optical state of the dressing mirror includes transmittance and reflectivity. The transmittance of the first adjustment layer 26 can be adjusted as needed to turn the dressing function of the sunshade device 100 on or off. The sunshade function and the dressing mirror function can be made independent of each other and have no influence on each other. The functional distinction is more obvious, so that the sunshade function and the makeup function can be better exerted and used.

[0087] In some embodiments of the present invention, when the sunshade device 100 turns off the dressing function, the first adjustment layer 26 is controlled to adjust the light transmittance in real time according to the light intensity, that is, when the light intensity increases, the light transmittance of the first adjustment layer 26 is controlled to decrease, thereby blocking more strong light; when the light intensity decreases, the light transmittance of the first adjustment layer 26 is controlled to increase, so that the user's field of vision can be clearer. The second adjustment layer 28 is controlled to adjust the light transmittance in real time according to the light intensity, that is, when the light intensity increases, the light transmittance of the second adjustment layer 28 is controlled to decrease, thereby blocking more strong light; when the light intensity decreases, the light transmittance of the second adjustment layer 28 is controlled to increase, so that the user's field of vision can be clearer. By controlling the light transmittance of the first adjustment layer 26 and the second adjustment layer 28 to adjust in real time, light can be provided in real time according to the light intensity and the needs of the user.

[0088] In other embodiments of the present invention, when the sunshade device 100 turns off the dressing function, it is not necessary to control the first adjustment layer 26 to adjust the light transmittance in real time according to the light intensity, but the first adjustment layer 26 is controlled to be in two states: sunshade and light transmittance. When the light intensity is greater than the external light intensity threshold, such as 60cd, the first adjustment layer 26 is controlled to play a role in blocking sunlight, and the light transmittance of the first adjustment layer 26 is adjusted to a first light transmittance, such as a light transmittance of 20%; when the light intensity is less than the external light intensity threshold, such as 60cd, the first adjustment layer 26 is controlled to play a role in enhancing the field of vision, and the light transmittance of the first adjustment layer 26 is adjusted to a second light transmittance, such as a light transmittance of 60%, and the second light transmittance is greater than the first light transmittance. It is not necessary to control the second adjustment layer 28 to adjust the light transmittance in real time according to the light intensity, but the second adjustment layer 28 is controlled to be in two states: sunshade and light transmittance. When the light intensity is greater than the external light intensity threshold, such as 60cd, the second adjustment layer 26 is controlled to play a role in shielding sunlight, and the transmittance of the second adjustment layer 28 is adjusted to the third transmittance, such as 20% transmittance; when the light intensity is less than the external light intensity threshold, such as 60cd, the second adjustment layer 28 is controlled to play a role in enhancing the field of vision, and the transmittance of the second adjustment layer 28 is adjusted to the fourth transmittance, such as 60% transmittance, and the fourth transmittance is greater than the third transmittance. By adjusting the transmittance of the first adjustment layer 26 to the first transmittance or the second transmittance according to the light intensity, the first adjustment layer 26 can block sunlight or enhance the field of vision, and the cost can be saved; by adjusting the transmittance of the second adjustment layer 28 to the third transmittance or the fourth transmittance according to the light intensity, the second adjustment layer 28 can block sunlight or enhance the field of vision, and the cost can be saved.

[0089] According to the control method of the sunshade device of the third aspect of the embodiment of the present invention, the transmittance of the second adjustment layer 28 is adjusted according to the intensity of light outside the vehicle to adjust the sunshade state of the second adjustment layer 28, so that the intensity of light passing through the sun visor 10 can be reduced to an appropriate intensity to reduce the glare of external strong light, make the user's visual effect comfortable, and expand the user's field of vision when using the sun visor; and, according to whether the sunshade device 100 turns on the dressing function, the transmittance of the first adjustment layer 26 is adjusted to adjust the optical state of the dressing mirror. The dressing function of the sunshade device 100 can be turned on or off by adjusting the transmittance of the first adjustment layer 26 as needed, so that the sunshade function and the makeup mirror function can be made independent of each other and do not affect each other, and the functional distinction is more obvious, so that the sunshade function and the makeup function can be better exerted and used.

[0090] According to some embodiments of the present invention, adjusting the light transmittance of the second adjustment layer 28 according to the intensity of light outside the vehicle includes:

[0091] According to the light intensity outside the vehicle, the transmittance of the second adjustment layer 28 is adjusted in real time. In this way, when the light intensity outside the vehicle changes, by adjusting the transmittance of the second adjustment layer 28 in real time, the light outside the vehicle can enter the vehicle and be filtered by the second adjustment layer 28, and then can be adjusted to the appropriate light intensity in real time.

[0092] For example, when the light intensity outside the vehicle increases, the transmittance of the second adjustment layer 28 is adjusted to decrease, thereby reducing the light passing through the sun visor 10 and avoiding glare; when the light intensity outside the vehicle decreases, the transmittance of the second adjustment layer 28 is adjusted to increase, so that the light can reach a suitable light intensity after passing through the sun visor 10, avoiding the light being too dark and causing unclear visibility of the road ahead.

[0093] According to some embodiments of the present invention, the transmittance of the second adjustment layer 28 is adjusted in real time according to the intensity of light outside the vehicle, including: adjusting the transmittance of the second adjustment layer 28 in real time to adjust the intensity of light passing through the sun visor 10 to less than or equal to the second light intensity threshold. The transmittance of the second adjustment layer 28 can be adjusted according to the intensity of light outside the vehicle, and the intensity of light passing through the sun visor 10 can be adjusted to less than or equal to the second light intensity threshold, so that the light entering the vehicle can be reduced to a suitable light intensity after passing through the second adjustment layer 28, so that the light intensity can be sufficient for the user to see the situation ahead clearly, and at the same time, the light can be prevented from being too strong and glaring.

[0094] The second light intensity threshold may be in the range of 30 cd to 40 cd.

[0095] According to some embodiments of the present invention, adjusting the light transmittance of the first adjustment layer 26 according to whether the sunshade device 100 turns on the dressing function includes:

[0096] When the sunshade device 100 turns on the dressing function, the light transmittance of the first adjustment layer 26 is adjusted to make the dressing mirror 50 reflective. For example, the light transmittance of the first adjustment layer 26 can be adjusted to be less than or equal to the first transparency threshold.

[0097] When the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 is adjusted to make the dressing mirror 50 light-transmissive. For example, the light transmittance of the first adjustment layer 26 can be adjusted to be greater than a first transparency threshold, for example, the first transparency threshold can be 60%;

[0098] The light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function is lower than the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns off the dressing function.

[0099] By making the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns on the dressing function lower than the light transmittance of the first adjustment layer 26 when the sunshade device 100 turns off the dressing function, when the sunshade device 100 turns on the dressing function, the light transmittance of the first adjustment layer 26 can be lower, and the dressing mirror 50 has reflective properties to present the function of a mirror; when the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 can be higher, and the dressing mirror 50 has light transmittance to avoid blocking the line of sight.

[0100] According to some embodiments of the present invention, when the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 is adjusted so that the dressing mirror 50 has light transmittance, including:

[0101] The light transmittance of the first adjustment layer 26 is adjusted so that the light intensity passing through the sun visor 10 is adjusted to be less than or equal to the first light intensity threshold. For example, when the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 can be adjusted according to the light intensity outside the vehicle so that the light intensity passing through the sun visor 10 is adjusted to be less than or equal to the first light intensity threshold. The first light intensity threshold can be in the range of 30cd to 40cd.

[0102] When the dressing function of the sunshade device 100 is turned off, the transmittance of the first adjustment layer 26 is adjusted so that the light intensity passing through the sun visor 10 is adjusted to be less than or equal to the first light intensity threshold, so that the light entering the vehicle can be reduced to an appropriate light intensity after passing through the first adjustment layer 26, which can make the light intensity sufficient for the user to see the situation ahead clearly, while avoiding glare caused by excessive light.

[0103] For example, the absolute value of the difference between the first light intensity threshold and the second light intensity threshold can be less than 5cd. In this way, when the sunshade device turns off the dressing function, the light intensity difference between the first area 24 and the second area 25 of the sun visor 10 is small. In this way, when the user uses it, the brightness of the outside world seen by the user through the first area 24 and the second area 25 is basically the same, thereby improving the user's visual experience.

[0104] According to some embodiments of the present invention, when the sunshade device 100 turns off the dressing function, the light transmittance of the first adjustment layer 26 is controlled to be greater than the first transparency threshold. In this way, when the sunshade device 100 turns off the dressing function, the first adjustment layer 26 can have good light transmittance, avoiding the first adjustment layer 26 from reflecting light due to low light transmittance and affecting the observation of the outside view of the vehicle.
