[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] An embodiment of the present invention provides a sun visor and a vehicle to solve the problem in the related art that the sun visor only has a full sun visor mode when opened, which reduces the driver's field of view to prevent glare from affecting driving safety, has poor practicality, and cannot provide users with a better user experience.

[0040] It should be noted that the shading effect of the deep shading mode is between that of the shallow shading mode and the full shading mode.

[0041] like Figure 1 As shown, an embodiment of the present invention provides a light-shielding plate, which may include: a mounting plate 1; a first light-transmitting plate 2, the first light-transmitting plate 2 being at least partially mounted on the mounting plate 1, the first light-transmitting plate 2 having a light-transmitting area 21; a second light-transmitting plate 3, the second light-transmitting plate 3 being connected to the mounting plate 1 or the first light-transmitting plate 2, so that the second light-transmitting plate 3 is configured to be in at least two position states; when the second light-transmitting plate 3 is in the first position state, the second light-transmitting plate 3 and the light-transmitting area 21 do not overlap along the light-transmitting direction, and the light-transmitting area 21 is in a shallow light-shielding state; when the second light-transmitting plate 3 moves to the second position state, the second light-transmitting plate 3 and the light-transmitting area 21 are overlapped, and the light-transmitting polarization direction of the second light-transmitting plate 3 is consistent with that of the light-transmitting area 21, and the second light-transmitting plate 3 and the light-transmitting area 21 together form a deep light-shielding state.

[0042] The first light-transmitting plate 2 and the second light-transmitting plate 3 can be injection-molded from a low-transmittance optical material, typically PC or PMMA, with a polarizing film attached, particularly with the polarization direction of the polarizing film set to 45°.

[0043] Specifically, in a driving scenario with low light, the second light-transmitting plate 3 can be set to the first position state, which does not overlap with the light-transmitting area 21 along the light-transmitting direction (the light-transmitting direction can be the light path before the light is about to enter the light-transmitting area 21), and the light-transmitting area 21 is in a shallow light-shielding state. At this time, the light-transmitting area 21 can block a small part of the light, and a part of the light can pass through the light-transmitting area 21, which will not completely block the driver's field of vision; in a driving scenario with strong light, the second light-transmitting plate 3 can be moved to the second position state, and the second light-transmitting plate 3 and the light-transmitting area 21 are not overlapped. The overlapping arrangement, and the light transmission polarization direction of the second light-transmitting plate 3 is consistent with that of the light-transmitting area 21 (the light transmission polarization directions of the polarizing films of the two are parallel), the second light-transmitting plate 3 and the light-transmitting area 21 jointly form a deep light-shielding state, or a smaller portion of light can pass through the second light-transmitting plate 3 and the light-transmitting area 21, and will not completely block the driver's field of vision; it provides users with a better use experience, and can use a shallow light-shielding mode or a deep light-shielding mode according to the light conditions, avoiding the problem of full light-shielding mode when the traditional sun visor is opened, which reduces the driver's field of vision and causes a sense of oppression to the driver.

[0044] In some embodiments, such as Figure 1 、 Figure 4 and Figure 5 As shown, the first light-transmitting plate 2 is provided with two first limiting portions 22, and the spacing direction of the two first limiting portions 22 is consistent with the translation direction of the second light-transmitting plate 3; the second light-transmitting plate 3 is provided with two second limiting portions 31 at intervals, and the spacing direction of the two second limiting portions 31 is consistent with the translation direction of the second light-transmitting plate 3; when the light-transmitting area 21 is in a shallow shading state, one of the first limiting portions 22 and the corresponding second limiting portion 31 are limited and fixed; when the shading plate is in a deep shading state, the other first limiting portion 22 and the corresponding other second limiting portion 31 are limited and fixed.

[0045] Among them, such as Figure 1 As shown, the first limiting portion 22 away from the mounting plate 1 can be in the rear end direction, and the end close to the mounting plate 1 can be in the front end direction. The two first limiting portions 22 and the two second limiting portions 31 can be spaced apart in the front-to-back direction, and the second light-transmitting plate 3 can be translated in the front-to-back direction; specifically, as Figure 4 and Figure 5As shown, when the second light-transmitting plate 3 is translated downward to overlap the light-transmitting area 21, the second light-transmitting plate 3 and the light-transmitting area 21 have the same light transmission polarization direction (both at 45 degrees), putting the light shielding plate in a deep light-shielding state. This allows the driver to translate the second light-transmitting plate 3 up and down to switch the light-shielding mode of the first light-transmitting plate 2 to a deep light-shielding mode.

[0046] Of course, the second light-transmitting plate 3 is not limited to the linear motion method to achieve the mode switching of the first light-transmitting plate 2, but can also be achieved by flipping and rotating. The second light-transmitting plate 3 flips and overlaps with the light-transmitting area 21, and the light transmission polarization direction of the second light-transmitting plate 3 is consistent with that of the light-transmitting area 21, so that the shading plate is in a deep shading state.

[0047] Of course, the second light-transmitting plate 3 can also be disassembled and assembled to change its position, so as to switch the light-shielding mode of the light-transmitting area 21 to the deep light-shielding mode.

[0048] In some embodiments, there can be one first limiter 22 and two second limiters 31. The first limiter 22 is located in the middle of the first light-transmitting plate 2, and the spacing between the two second limiters 31 is aligned with the translational direction of the second light-transmitting plate 3. The translational distance between the two second light-transmitting plates 3 is determined by the spacing between the two second limiters 31, which also represents the overlapping area between the second light-transmitting plate 3 and the light-transmitting region 21.

[0049] Of course, in some embodiments, the number of the first limiting portions 22 may be two, and the number of the second limiting portion 31 may be one; similarly, the second light-transmitting plate 3 may be translated to switch the light-shielding mode of the light-transmitting area 21 .

[0050] In some embodiments, such as Figure 1 As shown, the second limiting portion 31 and the first limiting portion 22 are magnetically attracted to each other for fixed position. When a force is applied to the second light-transmitting plate 3 to cause translation, the second limiting portion 31 and the first limiting portion 22 at the front end are released from the restraint due to the external force, allowing the second light-transmitting plate 3 to translate and overlap with the light-transmitting area 21, thereby achieving a deep light-shielding state. Furthermore, when the second light-transmitting plate 3 is translated forward, the second limiting portion 31 and the first limiting portion 22 at the rear end are released from the restraint, and the second limiting portion 31 and the first limiting portion 22 at the front end are again magnetically attracted to each other for fixed position, allowing the second light-transmitting plate 3 to translate and separate from the light-transmitting area 21, and the light-transmitting area 21 to enter a shallow light-shielding state.

[0051] Of course, in some embodiments, the second limiting portion 31 and the first limiting portion 22 can also be fixed by snapping together, and the plugging and unplugging direction of the snapping and fixing is consistent with the translation direction of the second light-transmitting plate 3 .

[0052] In some embodiments, such as Figure 7 As shown, when the second light-transmitting plate 3 moves to the third position, the second light-transmitting plate 3 is overlapped with the light-transmitting area 21, and the light transmission polarization direction of the second light-transmitting plate 3 is perpendicular to that of the light-transmitting area 21, and the second light-transmitting plate 3 and the light-transmitting area 21 together form a full light-shielding state.

[0053] The second light-transmitting plate 3 can be moved to its back side so that it overlaps with the light-transmitting area 21, so that the polarization directions of light transmitted by the second light-transmitting plate 3 and the light-transmitting area 21 are perpendicular (the polarization directions of light transmitted by the polarizing films of the two are perpendicular), thereby achieving a fully light-shielding state between the second light-transmitting plate 3 and the light-transmitting area 21. In extremely strong light conditions, the light can be completely blocked by the second light-transmitting plate 3 and the polarizing films on the light-transmitting area 21, allowing the light-shielding plate to be switched directly from a shallow light-shielding mode to a full light-shielding mode.

[0054] In some embodiments, such as Figure 1 、 Figure 6 He Ru Figure 7 As shown, the second light-transmitting plate 3 is connected to the first light-transmitting plate 2 through a flip structure 4. When the second light-transmitting plate 3 is flipped by the flip structure 4 to overlap with the light-transmitting area 21, the light transmission polarization direction of the second light-transmitting plate 3 is perpendicular to that of the light-transmitting area 21.

[0055] Among them, such as Figure 1 As shown, the rear end of the second light-transmitting plate 3 and the middle ends of the first light-transmitting plate 2 can be connected by a flip structure 4. When the second light-transmitting plate 3 is flipped, the magnetic attraction between the first limiting portion 22 and the second limiting portion 31 at the front end will be released. When the flip is completed, as shown in FIG. Figure 6 He Ru Figure 7 As shown, originally Figure 1 The second limiting portion 31 at the front end is turned to Figure 7 The lower end of the second light-transmitting plate 3 is magnetically adsorbed and fixed to the first limiting portion 22 at the lower end of the first light-transmitting plate 2 to ensure the stability of the second light-transmitting plate 3 after the flip is completed.

[0056] In some embodiments, such as Figure 1As shown, the flip structure 4 includes: a third limiting portion 41, which is arranged on the first light-transmitting plate 2; a fourth limiting portion 42, which is arranged on the second light-transmitting plate 3; the third limiting portion 41 and the fourth limiting portion 42 are limited and cooperated with each other, so that the second light-transmitting plate 3 is flipped with the fourth limiting portion 42 as the rotation axis.

[0057] In some embodiments, such as Figure 1 、 Figure 2 and Figure 3 As shown, a locking protrusion 32 is provided at one end of the second light-transmitting plate 3, and the light-shielding plate also includes an end cover 5, which is provided with a locking hole 51. The end cover 5 is assembled with the locking protrusion 32 through the locking hole 51 to be fixed to the second light-transmitting plate 3; the fourth limiting portion 42 includes a metal body, which is installed inside one end of the end cover 5, and the end cover 5 has an arc-shaped outer wall of one end of the metal body; the third limiting portion 41 includes a magnet, which is embedded and installed in the first light-transmitting plate 2, and the magnet and the metal body are attracted by magnetic force to be limited and fixed.

[0058] like Figure 1 As shown, the third limiting portion 41 and the corresponding fourth limiting portion 42 can also be magnetically attracted to each other to form a limited position. When switching from shallow shading mode to deep shading mode, the third limiting portion 41 and the corresponding fourth limiting portion 42 remain separated. The change in the internal position of the fourth limiting portion 42 relative to the end cap 5 does not hinder the forward or backward movement of the second light-transmitting plate 3, thereby achieving free switching between shallow and deep modes. The design of the locking hole 51 and the locking protrusion 32 makes the installation of the end cap 5 simple and convenient. The arc-shaped end of the end cap 5 with the fourth limiting portion 42 can improve the smoothness and stability of the second light-transmitting plate 3 during flipping.

[0059] In some embodiments, such as Figure 1 As shown, the mounting plate 1 is provided with a groove, one end of which extends to the outside of the mounting plate 1 ; the first light-transmitting plate 2 has a light-blocking area 23 , which is fixed in the groove.

[0060] Further, such as Figure 1 As shown, when the second light-transmitting plate 3 is in the first position, the second light-transmitting plate 3 is located in the groove and overlaps with the light-shielding area 23 .

[0061] The second light-transmitting plate 3 being in the first position may be a state where the second light-transmitting plate 3 is located in the groove and overlaps with the light-shielding area 23. This ensures that the light-shielding plate has a compact structure and does not occupy too much space.

[0062] In some embodiments, the embodiments of the present invention provide a vehicle, which includes a sun visor as described in some of the above embodiments. In a driving scenario with weak light, the second light-transmitting plate 3 can be set to the first position state, and does not overlap with the light-transmitting area 21 along the light-transmitting direction (its light-transmitting direction can be the light path before the light is about to enter the light-transmitting area 21), and the light-transmitting area 21 is in a shallow light-shielding state. At this time, the light-transmitting area 21 can block a small part of the light, and a part of the light can pass through the light-transmitting area 21, and will not completely block the driver's field of vision; in a driving scenario with strong light, the second light-transmitting plate 3 can be moved to the second position state, and the second light-transmitting plate 3 overlaps with the light-transmitting area 21. The second light-transmitting plate 3 and the light-transmitting area 21 are arranged together, and the light-transmitting polarization direction of the second light-transmitting plate 3 is consistent with that of the light-transmitting polarization direction of the polarization film of the two are parallel. The second light-transmitting plate 3 and the light-transmitting area 21 jointly form a deep light-shielding state, or a smaller part of the light can pass through the second light-transmitting plate 3 and the light-transmitting area 21, which will not completely block the driver's field of vision; it provides users with a better use experience, and can use a shallow light-shielding mode or a deep light-shielding mode according to the light conditions, avoiding the problem of full light-shielding mode when the traditional sun visor is opened, which reduces the driver's field of vision and brings a sense of oppression to the driver.
