Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle sun visor and a vehicle. Background Technology

[0002] Vehicle sun visors are typically installed above the heads of front-seat occupants to prevent glare from strong light, such as from direct sunlight. Sun visors are used very frequently and their angle can be adjusted to suit the needs of the occupants, thus avoiding direct sunlight on their eyes.

[0003] Traditional sun visors are generally made of plastic and are opaque. In order to block out strong light while maintaining sufficient visibility, drivers often need to manually adjust the position of the sun visor multiple times. This distraction of the driver in adjusting the position of the sun visor is detrimental to driving safety.

[0004] Some sun visors employ an electronically controlled color-changing scheme. This type of visor adjusts its light transmittance according to the intensity of ambient light, improving ease of use and reducing the frequency of manual adjustment by the driver. However, existing electronically controlled color-changing sun visors have the following technical problems: During use, the light transmittance of the entire electronically controlled color-changing area of ​​the visor adjusts synchronously. When the entire electronically controlled color-changing area is in shading mode, the driver still needs to manually adjust the visor position to obtain sufficient visibility while driving. When the entire electronically controlled color-changing area is in light-transmitting mode, the visor cannot effectively block strong light. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle sun visor and a vehicle to alleviate or eliminate at least one of the aforementioned technical problems.

[0007] Optionally, the light-sensing structure is located on the left or right side of the sunshade body.

[0008] Optionally, the light-sensing structure includes a light-sensing element whose length extends along the width direction of the vehicle sun visor, and a plurality of light-sensing parts are disposed on the light-sensing element.

[0009] Optionally, when the vehicle sun visor is in the open state, the light-sensing structure faces the front of the vehicle.

[0010] Optionally, it also includes a sunshade base, wherein the sunshade body is connected to the sunshade base, and the light-sensing structure is disposed on the sunshade base.

Detailed Implementation

[0026] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] like Figures 1 to 4 The vehicle sun visor 1 shown includes a sun visor body 12 and a light-sensing structure. The sun visor body 12 includes a plurality of electrically controlled dimming zones 124 that can independently adjust their light transmittance. The plurality of electrically controlled dimming zones 124 are arranged sequentially along the width direction of the vehicle sun visor 1. The light-sensing structure includes a plurality of light-sensing units that can detect light intensity. The positions of the plurality of light-sensing units in the width direction of the vehicle sun visor 1 correspond to the positions of the plurality of electrically controlled dimming zones 124 in the width direction of the vehicle sun visor 1.

[0029] By employing the above technical solution, a light-sensing structure can be installed on the vehicle sun visor 1 to detect the light intensity at the sun visor 1 in real time. This allows for the adjustment of the light transmittance of multiple electronically controlled dimming zones 124 using a controller on the sun visor 1 or other vehicle-mounted controllers, achieving zoned light blocking. By blocking light in these zones, areas with excessive light intensity can be blocked, while maintaining transparency in areas with lower light intensity, thus ensuring the user's field of vision.

[0030] The vehicle sun visor 1 can achieve the function of blocking light in sections, blocking excess light while better protecting the user's field of vision. When the vehicle sun visor 1 is installed above the driver's head, it only needs to be flipped open once during a driving trip. The driver does not need to manually adjust the position of the vehicle sun visor 1 during driving. The vehicle sun visor 1 can adjust the area of ​​strong light blocking according to changes in the intensity of external light, ensuring driving safety.

[0031] In a preferred embodiment, the light-sensing structure is located on the left or right side of the sun visor body 12. Arranging the light-sensing structure on the left or right side of the sun visor body 12 is both aesthetically pleasing and easy to implement. In a specific implementation, the light-sensing structure can be arranged in a long strip area on the left or right side of the sun visor body 12.

[0032] In some embodiments, the light-sensing structure includes a light-sensing element 13 extending along the width direction of the vehicle sun visor 1, and multiple light-sensing portions are disposed on the light-sensing element 13. Disposing of multiple light-sensing portions on a single light-sensing element 13 facilitates installation. In specific implementations, multiple sequentially arranged light-sensing portions can be formed on the light-sensing element 13 by arranging multiple light-sensing elements within the light-sensing element 13, with at least one light-sensing element disposed at each light-sensing portion.

[0033] Obviously, in other embodiments, multiple light-sensing elements can be sequentially installed in the elongated area on the left or right side of the sunshade body 12 to form multiple sequentially arranged light-sensing sections, with at least one light-sensing element arranged at each light-sensing section.

[0034] In some embodiments, in order to enable the light-sensing structure to better detect the light intensity at the vehicle sun visor 1, the light-sensing structure is usually placed on the front of the vehicle sun visor 1, that is, when the vehicle sun visor 1 is installed on the vehicle and the vehicle sun visor 1 is in the open state, the light-sensing structure faces the front of the vehicle.

[0035] In some embodiments, the vehicle sun visor 1 further includes a sun visor base 11, with the sun visor body 12 connected to the sun visor base 11, and a light-sensing structure disposed on the sun visor base 11. The sun visor base 11 provides mounting points for the sun visor body 12 and the light-sensing structure, facilitating their installation. In specific implementations, the vehicle sun visor 1 typically also includes a mounting seat 15 for connection to the vehicle, with the mounting seat 15 and the sun visor base 11 connected via a pivot structure. The sun visor base 11 can be formed by connecting a first housing 111 and a second housing 112.

[0036] As a specific example, the light sensor 13 is fixed to the sun visor base 11 by snap-fit ​​or screw-fit. The length of the light sensor 13 is greater than or equal to the width of the sun visor body 12. The second housing 112 of the sun visor base 11 is provided with a slot for the light sensor 13 to be exposed, so that the light sensor 13 can be exposed but does not protrude from the surface of the second housing 112. In a specific implementation, the light sensor 13 can be arranged 0.2mm below the surface of the second housing 112 to ensure the aesthetic appearance of the vehicle sun visor 1.

[0037] As a specific example, the sun visor body 12 is fixed to the sun visor base 11 by snap-fit ​​or screw-fit, and the first housing 111 and the second housing 112 are fixedly connected by snap-fit ​​or screw-fit. In a specific implementation, the sun visor base 11 can be configured as a frame structure surrounding the sun visor body 12, and the larger the proportion of the area of ​​the sun visor body 12 to the total area of ​​the vehicle sun visor 1, the better.

[0038] In some embodiments, the sunshade body 12 includes a liquid crystal dimming structure, which includes multiple liquid crystal dimming zones capable of independently adjusting their transmittance. Each of the multiple liquid crystal dimming zones is used to adjust the transmittance of a multiple electronically controlled dimming zone 124. The liquid crystal dimming structure is characterized by ease of implementation, high durability, high reliability, and high cost-effectiveness.

[0039] In some embodiments, such as Figure 5As shown, the sunshade body 12 also includes a first light-transmitting element 121 and a second light-transmitting element 123, with a liquid crystal dimming structure disposed between the first light-transmitting element 121 and the second light-transmitting element 123. In specific implementations, the first light-transmitting element 121 and the second light-transmitting element 123 can be made of glass. By sandwiching the liquid crystal dimming structure between the two pieces of glass, a frosted glass can be formed, which can controllably switch between a frosted state and a transparent state. More specifically, the frosted glass is made by laminating a liquid crystal film between two layers of glass. By applying an electric field, the arrangement of liquid crystal molecules is changed, thereby achieving the conversion between transparent and opaque glass. When there is no electric field, the liquid crystal molecules are arranged randomly, causing light to scatter, and the glass appears frosted (opaque); when an electric field is applied, the liquid crystal molecules are arranged neatly, allowing light to pass through smoothly, and the glass becomes transparent.

[0040] As a specific example, the liquid crystal dimming structure includes a liquid crystal dimming film 122, which can be configured to have multiple liquid crystal dimming zones whose transmittance can be adjusted independently. In a specific implementation, the liquid crystal dimming film 122 can be composed of multiple liquid crystal dimming film units spliced ​​together, and the transmittance of each of the multiple liquid crystal dimming film units can be adjusted independently. As a specific example, such as... Figure 5 As shown, the liquid crystal dimming film 122 is sandwiched between the first light-transmitting element 121 and the second light-transmitting element 123, and the first light-transmitting element 121, the liquid crystal dimming film 122 and the second light-transmitting element 123 can be bonded together with adhesive.

[0041] As a specific example, such as Figure 5 As shown, the vehicle sun visor 1 also includes a controller 14 connected to the sun visor body 12 and the light-sensing structure. The controller 14 is configured to control the light transmittance of multiple electronically controlled dimming zones 124 according to the light intensity detected by multiple light sensors. By placing the controller 14 on the vehicle sun visor 1, the arrangement space on the vehicle sun visor 1 is made reasonable use.

[0042] In practical implementation, multiple switch modules in the controller 14 can be used to control the power on and power off of multiple liquid crystal dimming zones respectively, thereby realizing the control of the light transmittance of multiple electronically controlled dimming zones 124 respectively.

[0043] like Figure 6 and Figure 7 As shown, when the vehicle sun visor 1 is installed on the vehicle 2, the vehicle sun visor 1 has two states: a working state and a non-working state. When the vehicle sun visor 1 is flush against the roof of the vehicle 2, the vehicle sun visor 1 is in the non-working state. When the vehicle sun visor 1 is in the open state, with its front facing the windshield 21 of the vehicle 2 and its back facing the driver 3, the vehicle sun visor 1 is in the working state. The specific working process of the vehicle sun visor 1 will be explained below using the working state of the vehicle sun visor 1 as an example.

[0044] When the driver 3 enters the vehicle, he can flip the vehicle sun visor 1 and open it to the working position. The vehicle sun visor 1 is connected to the vehicle's power supply and enters the working state. At this time, the sun visor body 12 is usually in a completely transparent state.

[0045] When the extended line 5 connecting the light source 4 and the lower boundary point of the black edge 22 of the windshield intersects with the light sensor 13, the light emitted by the light source 4 illuminates a portion of the light sensor 13. Theoretically, a dividing line 6 can be simulated between the illuminated and unilluminated portions of the light sensor 13. Areas above the dividing line 6 are areas without light, and areas below the dividing line 6 are areas with light. The illuminated portions of the light sensor generate signals, which are transmitted to the controller 14 via the light-sensing circuit. The controller 14, based on the received signals, controls the electronically controlled dimming zone 124 corresponding to the non-directly illuminated area above the dividing line 6 to be transparent, and the electronically controlled dimming zone 124 corresponding to the directly illuminated area below the dividing line 6 to be fogged, thus achieving partial light blocking. This blocks light that interferes with the driver 3 while avoiding blocking light that does not interfere with the driver 3, ensuring the driver 3's maximum field of vision.

[0046] When the extension line 5 of the line connecting the light source 4 and the lower boundary point of the black edge 22 of the windshield has exceeded the upper boundary point of the light sensor 13, the light sensor 13 is completely illuminated by light. The light sensor 13 generates a signal, which is transmitted through the light sensing circuit. The controller 14 receives the signal and controls the sun visor body 12 to adjust to a frosted state to block the light and prevent the light from interfering with the driver 3.

[0047] When the extension line 5 of the line connecting the light source 4 and the lower boundary point of the black edge 22 of the windshield has exceeded the lower boundary point of the light sensor 13, the light cannot reach the light sensor 13. The light sensor 13 will not generate a signal, and the sun visor body 12 will remain completely transparent. At this time, there is no interfering light, and the driver's field of vision is not disturbed.

[0048] In practical implementation, the light intensity can be used to determine whether the light will interfere with the driver 3. For example, if the light intensity detected by the light sensor is greater than a preset threshold, the judgment module in the controller 14 determines that the light will interfere with the driver 3; if the light intensity detected by the light sensor is not greater than the preset threshold, the judgment module in the controller 14 determines that the light will not interfere with the driver 3. Based on the above judgment results, the control module in the controller 14 controls the corresponding switch module to open or close, thereby controlling the light transmittance of the corresponding electronic dimming zone 124.
