Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, and more particularly to a sun visor and a vehicle. BACKGROUND

[0002] In the related art, a sun visor on a vehicle is installed above a driver's seat and a front passenger's seat, and is used to shield sunlight when the sunlight is strong. In addition, a mirror can be installed on the sun visor to serve as a makeup mirror. However, in the case where the sunlight is weak or the vehicle is in a stopped state, the sun visor cannot serve other purposes after being used as a makeup mirror, and thus the existing sun visor has a single function, which makes it difficult to fully utilize the sun visor. SUMMARY

[0003] The present application provides a sun visor and a vehicle, which can solve the problem that the function of a sun visor in a vehicle is single, which makes it difficult to fully utilize the sun visor.

[0004] The sun visor of the present application includes a sun visor body and a projection device. The projection device is disposed on the sun visor body.

[0005] In this way, by disposing the projection device on the sun visor, the sun visor can project entertainment information such as videos and movies to provide users with entertainment when the vehicle is in a stopped state and the electrochromic glass is adjusted to a transparent state, thereby solving the problem of a single function of the sun visor and making it possible to fully utilize the sun visor.

[0006] In some embodiments, the projection device is configured to project an image to the eyeball of a user.

[0007] In this way, by projecting the image projected by the projection device directly to the eyeball of the user, the virtual image distance of the projected image can be greater than 10 meters, which makes it possible to provide a large-size screen and increase the entertainment experience, and in addition, it is possible to avoid the discomfort such as dizziness caused by the close distance between the sun visor and the user and the close observation distance.

[0008] In some embodiments, the distance between the virtual image formed by the projection device and the eyeball of the user is greater than 10 meters.

[0009] In this way, by projecting the virtual image produced by the projection device to a distance of 10 meters from the eyeball of the user, it is possible for the user to watch the image at a long distance, which makes it possible to avoid the phenomenon of dizziness when the user watches the image for a long time.

[0010] In some embodiments, the projection device is a diffractive optical waveguide.

[0011] Therefore, by selecting the projection device as a diffraction optical waveguide, the diffraction optical waveguide can be arranged inside the sun visor body, without the need to additionally arrange a structure on the sun visor for fixing the projection device and occupying the interior space of the vehicle, thereby simplifying the structure of the sun visor and reducing the cost.

[0012] In some embodiments, the sun visor further comprises an electrochromic glass, and the projection device is arranged on a side of the electrochromic glass away from the user.

[0013] Therefore, by arranging the electrochromic glass on the side of the projection device facing the user, when the sun visor is in use, the electrochromic glass can be adjusted to be transparent, so that the projection device can project through the electrochromic glass, and when not in use, the electrochromic glass can be made opaque to hide the projection device behind the electrochromic glass.

[0014] In some embodiments, the sun visor body is formed with a mirror opening, the electrochromic glass is arranged in the mirror opening, and the sun visor further comprises a controller and a user input device, the controller being configured to control the electrochromic glass to become opaque as a mirror according to a user operation of the user input device.

[0015] Therefore, by forming the sun visor body with a mirror opening and arranging the electrochromic glass in the mirror opening, the electrochromic glass can be used as a mirror lens. By further comprising a controller and a user input device, the controller can control the light transmittance of the electrochromic glass to be 0 according to the user input instruction, so that the electrochromic glass can be used as a mirror, thereby saving the cost of re-arranging a mirror lens on the sun visor.

[0016] In some embodiments, the controller is further configured to control the electrochromic glass to become transparent to allow the projection device to project through the electrochromic glass according to a user operation of the user input device.

[0017] Therefore, the controller can also make the electrochromic glass transparent according to the control instruction input by the user on the user input device, i.e. the light transmittance of the electrochromic glass is not 0, so that the projection device can project through the electrochromic glass.

[0018] In some embodiments, the sun visor further comprises a sensor configured to detect the ambient brightness, and the controller is configured to adjust the light transmittance of the electrochromic glass to match the ambient brightness according to the ambient brightness.

[0019] Thus, by arranging the sensor on the sun visor, the controller can adjust the projection brightness of the projection device according to the light intensity, preventing too large light intensity difference from causing discomfort of the user during the viewing process.

[0020] In some embodiments, the sensor is arranged close to the light path of the projection device.

[0021] Thus, by arranging the sensor close to the light path of the projection device, the sensor can accurately acquire the light intensity of the external environment during projection, so as to timely adjust the projection light intensity, avoiding large light intensity difference and causing discomfort such as dizziness and glare of the user during the viewing process.

[0022] The vehicle of some embodiments of the present application comprises the sun visor of any one of the above.

[0023] Additional aspects and advantages of the embodiments of the present application will be in part apparent and in part pointed out below in the description of the embodiments of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0035] Please refer to Figure 1When the driver is driving the vehicle 10, the driver's eyes are often dazzled by sunlight or light from outside, causing visual fatigue or blurred vision, and thus causing a potential safety hazard. At this time, a sun visor 11 that completely blocks light is provided above the driver's position of the vehicle 10, and the sun visor 11 blocks the light from the driver's eyes. In addition, the sun visor 11 can be provided with a mirror as a dressing mirror. However, after the sun visor 11 is used as a dressing mirror, the sun visor 11 cannot perform other functions, and thus the sun visor 11 has a single function, and the sun visor 11 cannot be fully utilized.

[0036] To this end, referring to Figure 2 and Figure 3 , the sun visor 11 of the embodiment includes a sun visor body 111 and a projection device 112. The projection device 112 is provided on the sun visor body 111.

[0037] Thus, by providing the projection device 112 on the sun visor 11, when the vehicle 10 is in a stopped state, the sun visor body 111 can project entertainment information such as videos and movies by adjusting the electrochromic glass 113 to a transparent state, providing users with entertainment, and thus solving the problem of the single function of the sun visor 11, and fully utilizing the sun visor 11.

[0038] Specifically, the sun visor 11 on the vehicle 10 includes a sun visor body 111, which is substantially rectangular in shape, and includes a front cover 1111 and a rear cover 1112 connected to each other to form a receiving cavity, and the projection device 112 can be arranged in the receiving cavity. Further, a fixing structure 119 is provided on the sun visor body 111, which can be a fixed support. One end of the fixed support is fixed to the sun visor body 111 (i.e., the front cover 1111 and the rear cover 1112) by a nut or a rotating shaft connection, and the other end of the fixed support is fixed to the roof of the vehicle 10 by a nut or a rotating shaft connection, so that when the sun visor is not needed, the sun visor body 111 can be folded by the fixing structure 119, and when needed, it can be stretched down. Thus, by providing the fixing structure 119 on the sun visor 11, and making the sun visor body 111 movable by the fixing structure 119, the position of the sun visor 11 can be flexibly adjusted according to the height of the user's eyes, so that the sun visor 11 can prevent the user's line of sight from being blocked, and when projecting, the projection can be directly into the user's eyes, thus improving the user's viewing experience.

[0039] The sun visor 11 further comprises a projection device 112, which is capable of projecting an image. In some embodiments, the projection device 112 is capable of projecting the image into the eyeball of the user, and the virtual image distance of the projected image is greater than 10 meters, so as to provide a large-size screen and increase the entertainment experience, and also to avoid the sun visor 11 being too close to the user and directly imaging on the sun visor 11, which may cause dizziness and other discomforts after long-time use.

[0040] In some embodiments, the projection device 112 can be a diffractive optical waveguide, which comprises a coupling-in grating 1121, a waveguide substrate 1122, and a coupling-out grating 1123. The waveguide substrate 1122 can be the inner wall of a rectangular or circular channel formed in the rear cover 1112 of the sun visor 11, and the waveguide substrate 1122 comprises a first plane and a second plane which are parallel to each other, and the coupling-in grating 1121 and the coupling-out grating 1123 are arranged alternately on the first plane and the second plane. Thus, when the projection device 112 is in the working state, the incident light with image information is projected into the coupling-in grating 1121, and then transmitted or reflected into the waveguide substrate 1122 through the coupling-in grating 1121, and then transmitted to the coupling-out grating 1123 and coupled out into the eyeball of the user through the coupling-out grating 1123. In this way, by selecting the projection device 112 as a diffractive optical waveguide, the diffractive optical waveguide can be arranged inside the sun visor body 111, without the need for additional structures on the sun visor 11 to fix the projection device 112 and occupy the interior space of the vehicle 10, thereby simplifying the structure of the sun visor 11 and reducing the cost.

[0041] Please refer to Figure 3 In some embodiments, the sun visor 11 further comprises an electrochromic glass 113, and the projection device 112 is arranged on the side of the electrochromic glass 113 away from the user.

[0042] In this way, by arranging the electrochromic glass 113 on the side of the projection device 112 facing the user, the electrochromic glass 113 can be adjusted to be transparent when the sun visor 11 is in use, so that the projection device 112 can project through the electrochromic glass 113, and the electrochromic glass 113 can be made opaque when not in use, so as to hide the projection device 112 behind the electrochromic glass 113.

[0043] Specifically, the sun visor 11 further comprises an electrochromic glass 113, which has a shape matching that of the sun visor body 111, i.e., the electrochromic glass 113 is substantially rectangular in shape. The electrochromic glass 113 is capable of adjusting the light transmittance of the electrochromic glass 113 under the control of a voltage, so as to prevent or allow light to pass through the electrochromic glass 113.

[0044] The electrochromic glass 113 is arranged in the accommodating cavity formed by the sun visor body 111, and is clamped by the front cover 1111 and the rear cover 1112, so that the electrochromic glass 113 is fixed by the front cover 1111 and the rear cover 1112, thereby preventing the electrochromic glass 113 from being displaced due to the bumping of the vehicle 10.

[0045] The projection device 112 is arranged on the side of the electrochromic glass 113 away from the user, so that the exit light carrying image information coupled out through the coupling-out grating 1123 can pass through the transparent electrochromic glass 113 and enter the eyeball of the user.

[0046] Please refer to Figure 2 In some embodiments, the sun visor body 111 is formed with a vanity mirror opening 114, the electrochromic glass 113 is arranged in the vanity mirror opening 114, and the sun visor 11 further comprises a controller 115 and a user input device 116, the controller 115 is used to control the electrochromic glass 113 to become opaque as a vanity mirror according to the user operation of the user input device 116.

[0047] In this way, by forming the vanity mirror opening 114 on the sun visor body 111, and arranging the electrochromic glass 113 in the vanity mirror opening 114, the electrochromic glass 113 can be used as the lens of the vanity mirror. By further comprising the controller 115 and the user input device 116, the controller 115 can control the transmittance of the electrochromic glass 113 to be 0 according to the user input instruction, so that the electrochromic glass 113 can be used as a vanity mirror, thereby saving the cost of re-arranging the lens on the sun visor 11 as a vanity mirror.

[0048] Specifically, in some embodiments, the sun visor 11 has the function of a vanity mirror, by forming the vanity mirror opening 114 on the sun visor body 111, i.e. the vanity mirror opening 114 is arranged on the front cover 1111 of the sun visor 11 facing the user side, so that the user can make up from the vanity mirror opening 114. The electrochromic glass 113 can be arranged in the vanity mirror opening 114, so that the electrochromic glass 113 can be used as the lens of the vanity mirror.

[0049] The sun visor 11 further comprises a controller 115 and a user input device 116. The controller 115 can be an electronic control unit (ECU), which can be used to process the received electrical signals, and the user input device 116 can be a button, a knob or a touch display screen, etc., which can input the control instruction required by the user according to the user's needs.

[0050] The controller 115 is capable of connecting the electrochromic glass 113 and the user input device 116, in the case that the user needs to use the function of the mirror, the user inputs the control instruction of using the mirror function in the user input device 116, the controller 115 is capable of controlling the electrochromic glass 113 to become opaque according to the control instruction, so that the user can use the opaque electrochromic glass 113 to make up from the mirror opening 114.

[0051] For example, in the case that the user needs to use the mirror to make up, by pressing the button of using the mirror, or adjusting the knob of using the mirror, or clicking the interface of using the mirror on the touch screen, the electronic control unit is capable of receiving the electrical signal of using the mirror, so as to control the control voltage of the electrochromic glass 113, so that the light transmittance of the electrochromic glass 113 is adjusted to 0, that is, the electrochromic glass 113 becomes opaque, so that the user can make up through the opaque electrochromic glass 113 from the mirror opening 114.

[0052] Please refer to Figure 2 In some embodiments, the controller 115 is further configured to control the electrochromic glass 113 to become transparent according to the user operation of the user input device 116, so as to allow the projection device 112 to project through the electrochromic glass 113.

[0053] In this way, the controller 115 is also capable of making the electrochromic glass 113 transparent according to the control instruction input by the user in the user input device 116, that is, the light transmittance of the electrochromic glass 113 is not 0, so that the projection device 112 can project through the electrochromic glass 113.

[0054] Specifically, in the case that the user needs to use the projection function of the sun visor 11, the user inputs the control instruction of using the projection function in the user input device 116, the controller 115 is capable of making the electrochromic glass 113 transparent according to the control instruction, so that the projection device 112 can project through the electrochromic glass 113.

[0055] For example, in the case that the user needs to use the projection function of the sun visor 11, by pressing the button of using the projection function, or adjusting the knob of using the projection function, or clicking the interface of using the projection function on the touch screen, the electronic control unit is capable of receiving the electrical signal of using the projection device 112, so as to control the control voltage of the electrochromic glass 113, so that the light transmittance of the electrochromic glass 113 is adjusted to not 0, that is, the electrochromic glass 113 becomes transparent, so that the projection device 112 can project through the transparent electrochromic glass 113 from the mirror opening 114.

[0056] Please refer to Figure 2 and Figure 3In some embodiments, the sun visor 11 further comprises a sensor 117 for detecting ambient brightness, and the controller 115 is configured to adjust the light transmittance of the electrochromic glass 113 according to the ambient brightness.

[0057] In this way, by providing the sensor 117 on the sun visor 11, the controller 115 can adjust the projection brightness of the projection device 112 according to the light intensity, preventing excessive light intensity difference from causing discomfort to the user during viewing.

[0058] Specifically, the sun visor 11 further comprises a sensor 117, which can be a light sensor, such as a high-precision Silicon Photo Diode (SPD). The sensor 117 is disposed on the sun visor body 111, and the sensor 117 is disposed close to the light path projected by the projection device 112, i.e., the sensor 117 can be disposed on the front cover 1111 close to the user side and along the projected light path. The sensor 117 can be used to detect the light intensity of the environment in which the vehicle 10 is located, and transmit the detected light intensity data to the controller 115 connected to the sensor 117, so that the controller 115 can adjust the projection brightness according to the light intensity data. Therefore, the sensor 117 can accurately obtain the light intensity of the external environment during projection, and timely adjust the projection light intensity.

[0059] For example, in the case where the user needs to use the projection function of the sun visor 11, in order to avoid excessive light intensity difference from causing dizziness, glare and other uncomfortable phenomena to the user during viewing of the projection, at this time, it is necessary to adjust the projection brightness to keep balance with the brightness of the external environment. After the projection device 112 starts projection, the controller 115 can obtain the light intensity generated by the projection, denoted as L0, at this time, the light sensor can obtain the light intensity of the external environment, denoted as L1. The light sensor transmits the obtained light intensity L1 to the controller 115, and the controller 115 can compare the light intensity L1 with the light intensity L0, so that the controller 115 adjusts the control voltage of the electrochromic glass 113 according to the light intensity difference, so that the light transmittance of the electrochromic glass 113 reaches the optimal value, thereby improving the user's experience of viewing the projection.

[0060] Optionally, referring to Figure 2 , Figure 3 and Figure 4 , the sun visor 11 further comprises an image generation device 118 connected to the projection device 112, and the image generation device 118 is configured to generate an image and transmit the image to the projection device 112.

[0061] Therefore, by arranging the image generation device 118 on the sun visor 11, the image information generated by the image generation device 118 can be received by the projection device 112 and projected, so as to solve the problem of single function of the sun visor 11.

[0062] Specifically, the sun visor 11 further comprises the image generation device 118, which can be a graphics processing unit (GPU). The image generation device 118 can be used to generate the image required for projection. The image generation device 118 can be arranged on the sun visor 11 and connected with the projection device 112. For example, the image generation device 118 can be arranged on the outer cover of the sun visor 11, so that the light containing the image generated by the image generation device 118 can enter the projection device 112.

[0063] In some embodiments, the image generation device 118 can also be arranged outside the sun visor 11. For example, the image generation device 118 can be fixed on the roof of the vehicle 10 by a support and arranged in the same plane as the projection device 112 of the sun visor 11, so that the light containing the image generated by the image generation device 118 can enter the projection device 112.

[0064] Please refer to Figure 1 The vehicle 10 of the embodiments of the present application comprises the sun visor 11 of the above embodiments.

[0065] According to the vehicle 10 of the embodiments of the present application, the sun visor 11 of the above embodiments can realize the functions of better shading and dressing mirror, can avoid the safety hazard to a certain extent, and the user can make up. In addition, the sun visor 11 of the vehicle 10 also has the function of projection, so that the sun visor 11 of the vehicle 10 is fully utilized.
