[0044] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The sun visor provided by the embodiment of the present application can be used in a vehicle. Specifically, the sun visor can be arranged on the driver side and the co-driver side of the vehicle and mainly used for blocking sunlight. The sun visor provided by the embodiment of the present application can be provided with a display device so as to allow a user to watch a video and the like, thereby improving the user's experience of riding.

[0046] With reference to Figures 1 to 4 , a structural schematic diagram of a sun visor is shown. As shown in Figures 1 to 4 , the sun visor specifically can include a sun visor body 10, a display device 106 arranged on the sun visor body 10, and a position adjusting mechanism 11 connected to the sun visor body 10. The position adjusting mechanism 11 has a multi-degree-of-freedom function and can be used to connect with a vehicle body so as to allow the sun visor body 10 to move in multiple degrees of freedom relative to the vehicle body.

[0047] In the embodiment of the present application, the position adjusting mechanism 11 can be connected between the sun visor body 10 and the vehicle body. Since the position adjusting mechanism 11 has a multi-degree-of-freedom adjusting function, under the action of the position adjusting mechanism 11, the sun visor body 10 can move in multiple degrees of freedom relative to the vehicle body, so as to adapt to the multi-angle watching function of the display device 106 on the sun visor body and improve the user's personalized watching experience.

[0048] In a specific application, the position of the vehicle body for mounting the sun visor can be a roof 20. Specifically, the sun visor can be mounted at the roof 20 of the driver's cabin or the co-driver's cabin. Since the sun visor body 10 can move in multiple degrees of freedom relative to the roof 20, the display device 106 on the sun visor body 10 can be correspondingly adjusted in multiple degrees of freedom, so as to allow users in different positions and postures in the vehicle to obtain better watching effect.

[0049] For example, as shown in Figure 1 , by adjusting the position of the sun visor body 10, a user in a co-driver's lying position can obtain better watching effect. As shown in Figure 2 , by adjusting the position of the sun visor body 10, a user in a rear seat watching mode can obtain better watching effect. As shown in Figure 3 , by adjusting the position of the sun visor body 10, a user in a co-driver's sitting position can obtain better watching effect. As shown in Figure 4 , by adjusting the position of the sun visor body 10, a user in a rear seat sitting position can obtain better watching effect.

[0050] In the embodiment of the present application, because the sun visor body 10 can achieve multi-degree-of-freedom position adjustment, the sun visor body 10 has a wide range of movement. During use, the display device 106 on the sun visor body 10 can be extended to a position below the rearview mirror. This allows the display device 106 to be viewed not only by the front passenger but also by rear passengers or the driver. This expands the user base of the sun visor display device 106 and improves the cost-effectiveness and practicality of the display device 106. Furthermore, due to the wide range of movement of the sun visor body 10, it can block light from a wider angle, achieving a better sunshade effect during certain periods of daytime.

[0051] In the embodiment of the present application, the multiple degrees of freedom include at least two of the following: translation along the X-axis, translation along the Y-axis, translation along the Z-axis, rotation about the X-axis, rotation about the Y-axis, and rotation about the Z-axis, so that the sun visor body 10 can move in at least two of the above degrees of freedom. Specifically, the X-axis can be the front-to-back direction of the vehicle, the Y-axis can be the left-to-right direction of the vehicle, and the Z-axis can be the up-down direction of the vehicle.

[0052] In some optional embodiments of the present application, the position adjustment mechanism 11 is connected to the back of the sun visor body 10, which can prevent the fixing part 105 of the position adjustment mechanism 11 from occupying the front area of ​​the sun visor body 10, thereby facilitating the increase of the exposed area of ​​the front of the sun visor body 10, thereby increasing the display area of ​​the display device 106, and further enhancing the user's viewing experience of the display device 106.

[0053] It should be noted that, in specific applications, those skilled in the art may also set the position adjustment mechanism 11 on the side or other positions of the sun visor body 10 as needed. The embodiment of the present application does not specifically limit the connection position of the position adjustment mechanism 11 on the sun visor body 10.

[0054] like Figure 5 As shown, the sun visor body 10 may specifically include: a front cover 101, a rear cover 102, a projection module 103, a circuit board 104 and a fixing member 105; wherein, the front cover 101 and the rear cover 102 enclose a accommodating cavity, the projection module 103 and the circuit board 104 are arranged in the accommodating cavity, and the display device 106 is connected to the front cover 101 through the fixing member 105; the position adjustment mechanism 11 is connected to the rear cover 102.

[0055] In a specific application, the display device 106 can be at least partially exposed to the front cover plate 101, so as to facilitate the user to view the display content on the display device 106. The position adjusting mechanism 11 can be connected to the rear cover plate 102, so as to avoid blocking the display device 106 on the front cover plate 101 and increase the display area of the display device 106. The fixing member 105 can be used to fix and support the display device 106 and connect the display device 106 to the front cover plate 101, and the projection module 103 can be used to implement the projection function. In actual application, the projection module 103 and the display device 106 can be electrically connected to the circuit board 104, so as to realize power access and data transmission through the circuit board 104.

[0056] Optionally, the display device 106 is a light wave guide projection device, that is, the display device 106 can use light wave guide transmission and exit into the human eye through a diffraction grating. Since the light wave guide projection device has stronger reality, the image plane distance from the human eye distance is longer, and the image plane size is larger, and in addition, the position adjusting mechanism 11 of the embodiment of the present application realizes multi-degree-of-freedom movement, which can make the display device 106 on the sun visor better match the human eye position, so that the user obtains the best viewing effect and greatly improves the user's viewing experience.

[0057] As shown in Figure 6 The position adjusting mechanism 11 can include a universal shaft position adjusting mechanism. Since the universal shaft position adjusting mechanism can realize position adjustment in multiple directions, under the action of the universal shaft position adjusting mechanism, the display device 106 on the sun visor body 10 can realize position adjustment in multiple directions, further improving the position adjustment flexibility of the display device 106 to adapt to multi-directional viewing needs.

[0058] Optionally, the universal shaft position adjusting mechanism includes at least one universal shaft coupling. The at least one universal shaft coupling can be used to realize movement of the sun visor body 10 relative to the vehicle body in at least two degrees of freedom, thereby increasing the movement range of the sun visor body 10.

[0059] As shown in Figure 6 The universal shaft position adjusting mechanism can specifically include a first universal shaft coupling 111, a second universal shaft coupling 112, a third universal shaft coupling 113, a first connecting rod 114, and a second connecting rod 115. The first connecting rod 114 and the second connecting rod 115 can each include a first end and a second end arranged away from each other. The sun visor body 10 and the first end of the first connecting rod 114 are connected through the first universal shaft coupling 111, the second end of the first connecting rod 114 and the first end of the second connecting rod 115 are connected through the second universal shaft coupling 112, and the second end of the second connecting rod 115 and the roof 20 of the vehicle body are connected through the third universal shaft coupling 113.

[0060] In a specific application, since the universal shaft coupler can realize free rotation in a direction, by arranging three universal shaft couplers, not only the display device 106 on the sun visor body 10 can realize free rotation in multiple directions, but also the rotation range is relatively large, so that the position adjustment flexibility and adjustment range of the display device 106 can be considered, so that the display device 106 can better match the user's eye position, and the user can obtain the best viewing effect.

[0061] Optionally, the length of the second connecting rod 115 is greater than the length of the first connecting rod 114, so as to further improve the position adjustment range of the display device 106.

[0062] In actual application, by arranging the position adjustment mechanism 11 as a universal shaft position adjustment mechanism, the position adjustment mechanism 11 can have the functions of folding and unfolding. When the display device 106 on the sun visor body 10 needs to be used, the position adjustment mechanism 11 can be unfolded, and when the display device 106 on the sun visor body 10 does not need to be used, the position adjustment mechanism 11 can be folded. By arranging the length of the second connecting rod 115 to be greater than the length of the first connecting rod 114, not only can the operation of unfolding and adjusting the position adjustment mechanism 11 be facilitated, but also the adjustment range of the position adjustment mechanism 11 can be increased.

[0063] Optionally, the length of the second connecting rod 115 is 28-32 cm, and / or the length of the first connecting rod 114 is 16-20 cm, so that the position adjustment mechanism 11 is not only easy to unfold and fold, but also has a relatively large adjustment range.

[0064] For example, the length of the second connecting rod 115 can be 28 cm, 29 cm, 30.5 cm or 32 cm, and the length of the first connecting rod 114 can be 16 cm, 18 cm, 19.5 cm or 20 cm, and the length of the first connecting rod 114 and the second connecting rod 115 is not limited in the embodiment of the application.

[0065] Optionally, one or more of the first universal shaft coupler 111, the second universal shaft coupler 112 and the third universal shaft coupler 113 can be a cross universal shaft coupler, so as to facilitate the installation of the first universal shaft coupler 111, the second universal shaft coupler 112 and the third universal shaft coupler 113 on the ceiling 20, the sun visor body 10, the first connecting rod 114 and the second connecting rod 115.

[0066] It should be noted that in specific applications, the first universal shaft coupling 111, the second universal shaft coupling 112, and the third universal shaft coupling 113 can also be any one of a ball hinge plunger type universal coupling, a ball fork type universal coupling, and a ball cage type universal coupling. The embodiments of the present application do not limit the specific content of the first universal shaft coupling 111, the second universal shaft coupling 112, and the third universal shaft coupling 113.

[0067] Optionally, the angle adjustment range of one or more of the first universal shaft coupling 111, the second universal shaft coupling 112, and the third universal shaft coupling 113 is greater than or equal to 45°, so that the position adjustment mechanism 11 as a whole can realize rotation in multiple directions exceeding 90°, so that users in any position in the vehicle can obtain the best viewing effect.

[0068] As shown in Figure 7 The position adjustment mechanism 11 can specifically include a sliding rail 116, a sliding block 117, and an extension piece 118. The sliding rail 116 extends in a first direction, one end of the sliding rail 116 is provided with a hinge piece, which can be used to connect with the vehicle body to realize the up-down flipping of the sun visor body 10. The sliding block 117 is slidingly connected to the sliding rail 116, and the extension piece 118 is connected between the sun visor body 10 and the sliding block 117 to drive the sun visor body 10 to extend and retract in a second direction perpendicular to the first direction.

[0069] In specific applications, since the sun visor body 10 is connected to the sliding block 117 through the extension piece 118, when the sliding block 117 slides on the sliding rail 116 in the first direction, it can drive the sun visor body 10 to correspondingly adjust the position in the first direction. Since the extension piece 118 can extend and retract in the second direction, it can correspondingly drive the sun visor body 10 to extend and retract in the second direction, so that the sun visor body 10 adjusts the position in the second direction. That is, through the position adjustment mechanism 11 shown in Figure 7 The sun visor body 10 can realize position adjustment in the first direction and the second direction, and the adjustment accuracy is high.

[0070] For example, the first direction can be the up-down direction of the vehicle, and the second direction can be the front-rear direction of the vehicle. Alternatively, the first direction is the front-rear direction of the vehicle, and the second direction is the up-down direction of the vehicle. The embodiments of the present application do not limit the specific directions of the first direction and the second direction. The embodiments of the present application are only described by taking the first direction as the up-down direction of the vehicle and the second direction as the front-rear direction of the vehicle as an example.

[0071] In some optional embodiments of the present application, the telescopic member 118 may be at least one of a diamond hinge and a telescopic rod, so that the structure of the telescopic member 118 is relatively simple and the telescopic stability is better.

[0072] Optionally, a groove is provided on the sun visor body 10, which can be used to accommodate the telescopic member 118, thereby reducing the space occupied by the telescopic member 118. In particular, when the telescopic member 118 is in a retracted state, the telescopic member 118 can be partially or completely retracted into the groove, thereby further increasing the telescopic range of the telescopic member 118, thereby further increasing the position adjustment range of the sun visor body 10.

[0073] In summary, the sun visor described in the embodiments of the present application has at least the following advantages:

[0074] In this embodiment of the present application, the sun visor is provided with a position adjustment mechanism that can be connected between the sun visor body and the vehicle body. Because the position adjustment mechanism has a multi-degree-of-freedom adjustment function, the sun visor body can be moved with multiple degrees of freedom relative to the vehicle body under the action of the position adjustment mechanism to accommodate the user's multi-angle viewing function of the display device on the sun visor, thereby enhancing the user's personalized viewing experience.

[0075] The present application also provides a vehicle, which may include the aforementioned sun visor and a vehicle body, with the sun visor's position adjustment mechanism connected to the vehicle body. It should be noted that in the present application, the structure of the sun visor is identical to that of the sun visor described in any of the aforementioned embodiments, and its beneficial effects are similar, and therefore will not be further described here. Optionally, the position adjustment mechanism is connected to the roof of the vehicle body.
