The dimension b2 in fig. 1 shows the rim width of the rear view mirror 100 when the antiglare unit 4 is in the second state.
According to the rearview mirror 100 of the embodiment of the invention, by setting the width of the front end face of the side wall of the second mounting bracket 2 to be smaller than the width of the front end face of the side wall of the first mounting bracket 1, when the anti-dazzle unit 4 is in the first state, the frame width of the rearview mirror 100 can be reduced, the narrow frame design of the rearview mirror 100 is realized, and the mirror surface area of the rearview mirror 100 is larger and the appearance is more attractive.
According to some embodiments of the invention, the sidewall thickness of the second mounting bracket 2 remains unchanged in the front-to-back direction. As shown in fig. 1 and 2, the thickness of the side wall of the second mounting bracket 2 remains unchanged in the front-to-back direction, and at this time, the thickness of the side wall of any place of the second mounting bracket 2 is equal to the width of the front end face of the side wall of the second mounting bracket 2. Thereby, the structure of the second mounting bracket 2 can be simplified, which is advantageous in improving the processing efficiency.
In other embodiments of the present invention, the first inclined portion 22 is provided on the inner surface of the side wall of the second mounting bracket 2, the second inclined portion 41 that mates with the first inclined portion 22 is provided on the antiglare unit 4, and the first inclined portion 22 extends in a direction from front to rear toward a central axis of the second mounting space 21.
As shown in fig. 3, the first inclined portion 22 may be provided near the front end surface of the second mounting bracket 2. As shown in fig. 5, the front end of the first inclined portion 22 may extend onto the front end surface of the second mounting bracket 2. The second inclined portion 41 of the antiglare unit 4 corresponds to the first inclined portion 22. Thus, by providing the first inclined portion 22 on the inner surface of the side wall of the second mounting bracket 2 and providing the second inclined portion 41 on the antiglare unit 4 that mates with the first inclined portion 22, the contact area of the antiglare unit 4 and the second mounting bracket 2 can be increased, the width of the front end face of the side wall of the second mounting bracket 2 can be reduced while the connection reliability between the antiglare unit 4 and the second mounting bracket 2 is improved, and the frame width of the rear view mirror 100 can be further reduced.
In addition, by utilizing the cooperation between the first inclined portion 22 and the second inclined portion 41, when the rear view mirror 100 receives a side impact, the antiglare unit 4 can move along the first inclined portion 22, so that the side impact can be buffered, the antiglare unit 4 can absorb impact energy, the deformation amount of the antiglare unit 4 can be reduced, the failure rate of the antiglare unit 4 can be reduced, and the reliability of the rear view mirror 100 can be improved.
According to some embodiments of the present invention, the first inclined portion 22 is gradually inclined in a direction approaching the central axis of the second installation space 21 in the front-to-rear direction. Thereby, the structure of the second mounting bracket 2 can be simplified, the production period can be shortened, and the production cost can be saved.
Further, as shown in fig. 3 and 4, both the first inclined portion 22 and the second inclined portion 41 may be formed in inclined planes, thereby not only simplifying the structure of the rear view mirror 100, simplifying the processing of the rear view mirror 100, but also improving the stability of the engagement of the first inclined portion 22 with the second inclined portion 41. Meanwhile, when the rear view mirror 100 receives a side impact, the anti-dazzle unit 4 is convenient to move along the first inclined portion 22, so that the side impact can be effectively buffered, impact energy is absorbed, the deformation amount of the anti-dazzle unit 4 is reduced, the failure rate of the anti-dazzle unit 4 can be effectively reduced, and the reliability of the rear view mirror 100 is improved.
According to some embodiments of the present invention, the display unit 3 includes a display region and a non-display region, the non-display region being located outside the non-display region, and the non-display region being opposite to the front end surface of the first mounting bracket 1 to shield the non-display region by the front end surface of the first mounting bracket 1. It is understood that the non-display area may be formed outside at least one side edge of the display area. For example, in some embodiments of the invention, non-display areas are provided outside of each edge of the display area. The non-display area is formed in a ring shape and surrounds the outer circumference of the display area. The non-display area may be used for wiring or the like for arranging the display unit 3.
Alternatively, the inner contour of the projection area of the front end surface of the first mounting bracket 1 on the display unit 3 coincides with the inner contour of the non-display area, or the inner contour of the projection area of the front end surface of the first mounting bracket 1 on the display unit 3 is located inside the inner contour of the non-display area. Thereby, the front end surface of the first mounting bracket 1 can be ensured to completely shield the non-display area of the display unit 3, the circuit of the display unit 3 is prevented from being exposed, and the appearance aesthetic property of the rearview mirror 100 is improved.
According to some embodiments of the present invention, as shown in fig. 8 and 9, the antiglare unit 4 has a first region 42 and a second region 43, the second region 43 surrounding the outer circumference of the first region 42, the first region 42 being opposite to the display region, and in the second state, the first region 42 is in a transparent state. As shown in fig. 9, the second region 43 is formed in a ring shape and surrounds the outer periphery of the first region 42. In the second state, the first area 42 is in a transparent state, so that external environment light is favorably irradiated onto the display unit 3 through the first area 42, and emergent light of the display unit 3 can transmit the first area 42, thereby ensuring the display quality of the display unit 3 and avoiding interference of the anti-dazzle unit 4 on a display picture of the display unit 3.
According to some embodiments of the invention, the antiglare unit 4 is in the second state, the second region 43 being in a specular state. Specifically, in the second state, the antiglare unit 4 has the first region 42 in a transparent state and the second region 43 in a mirror state. In this way, the front end surface of a portion of the side wall of the second mounting bracket 2 can be shielded by the second region 43, so that the rim width of the rear view mirror 100 in the second state can be visually reduced, and the appearance of the rear view mirror 100 can be further optimized.
According to further embodiments of the invention, in the second state, the second region 43 is formed as a pattern area. In the present embodiment, in the second state, the first region 42 is in a transparent state, and the second region 43 may exhibit a patterned area thereon. The pattern on the second area 43 may be a texture map, a landscape map, an animal and plant map, or the like. Thereby, the rim width of the rear view mirror 100 in the second state can also be visually reduced.
According to some embodiments of the invention, the front projection of the first area 42 onto the display unit 3 coincides with the display area. Thereby, the display quality of the display unit 3 can be ensured, and the bezel width of the rear view mirror 100 in the second state can be minimized.
According to some embodiments of the present invention, the front end surface of the side wall of the second mounting bracket 2 is located at the front side of the antiglare unit 4, and the front end surface of the side wall of the second mounting bracket 2 extends inward beyond the outer edge of the antiglare unit 4. As shown in fig. 2, the front end surface of the side wall of the second mounting bracket 2 shields a part of the antiglare unit 4. In this way, the front end face of the side wall of the second mounting bracket 2 can shield the line at the edge of the anti-dazzle unit 4, so that the line in the anti-dazzle unit 4 is prevented from being exposed, and the front end face of the side wall of the second mounting bracket 2 can limit the anti-dazzle unit 4, so that the position in the anti-dazzle unit 4 is more stable.
Since the antiglare unit 4 has fewer lines, the front end surface of the side wall of the second mounting bracket 2 can be extended inward to a position about 1mm beyond the outer edge of the antiglare unit 4.
According to some embodiments of the present invention, as shown in fig. 10 and 11, the antiglare unit 4 includes an antiglare shield 44 and a semi-reflective and semi-permeable film 45, the antiglare shield 44 includes a first substrate 441, a second substrate 442, and a liquid crystal 443 disposed between the first substrate 441 and the second substrate 442, the second substrate 442 is disposed on a side of the first substrate 441 adjacent to the display unit 3, at least one side edge of the second substrate 442 extends beyond the first substrate 441, and a portion of the second substrate 442 beyond the first substrate 441 forms a bezel area 444. The semi-reflective and semi-permeable film 45 is located between the antiglare screen 44 and the display unit 3.
Specifically, one or more side edges of the second substrate 442 may extend beyond the first substrate 441 to form the bezel area 444. For example, in the example of fig. 12, the upper side edge of the second substrate 442 extends beyond the first substrate 441. The bezel area 444 is formed at an upper side edge of the second substrate 442. In the example of fig. 13, the lower side edge of the second substrate 442 extends beyond the first substrate 441. In the example of fig. 14, the right edge of the second substrate 442 extends beyond the first substrate 441. In this way, it is convenient to provide a member such as a photosensor on the antiglare unit 4.
Specifically, referring to fig. 10 and 11, the first and second substrates 441 and 442 may encapsulate the liquid crystal 443 therebetween. The transflective film is disposed on a side of the second substrate 442 facing away from the liquid crystal 443. The first substrate 441 is provided with a first electrode 446 near the liquid crystal 443, the second substrate 442 is provided with a second electrode 447 near the liquid crystal 443, an electric field is formed between the first electrode 446 and the second electrode 447, the electric field can drive the liquid crystal 443 to deflect, so that the deflection angle of the liquid crystal 443 can be controlled by changing the direction of the electric field, the liquid crystal 443 is deflected to an angle corresponding to the first state in the first state (as shown in fig. 10), and the liquid crystal 443 is deflected to an angle corresponding to the second state in the second state (as shown in fig. 11).
The first electrode 446 and the second electrode 447 may be any electrodes, for example, planar electrodes, stripe electrodes, slit electrodes, or the like, and are not limited thereto.
The first substrate 441 has a first polarizer 445 on a side facing away from the liquid crystal 443. When the external ambient light enters the antiglare unit 4, the external ambient light becomes linear polarized light after passing through the first polarizer 445, the liquid crystal 443 modulates the polarization state of the linear polarized light by different deflection angles, if the liquid crystal 443 is deflected to an angle corresponding to the first state (as shown in fig. 10), the polarization direction of the light component after passing through the liquid crystal 443 can be made parallel to the extension direction of the transflective film, so that the light component is reflected out of the antiglare unit 4 to form a mirror surface, and if the liquid crystal 443 is deflected to an angle corresponding to the second state (as shown in fig. 11), the polarization direction of the light component after passing through the liquid crystal 443 can be made not parallel to the extension direction of the transflective film, so that the light component is transmitted, and the display unit 3 can display pictures.
The display unit 3 includes a display panel 31, a second polarizer 32 is disposed on one side of the display panel 31 near the anti-dazzle unit 4, the second polarizer 32 is used for assisting the display panel 31 to display, and a third polarizer 33 may be disposed on the opposite side of the display panel 31 and the second polarizer 32.
According to some embodiments of the present invention, the rearview mirror 100 also includes a light-sensitive sensor disposed at the bezel area 444. The light sensor may sense the intensity of light. The anti-dazzle unit 4 may adjust the polarization state of incident ambient light by controlling the voltage applied to the anti-dazzle unit 4 according to the intensity of light sensed by the light sensing sensor, and adjust the reflection of the incident ambient light by the semi-reflective and semi-permeable membrane 45, and similarly adjust the polarization state of the image light transmitted from the semi-reflective and semi-permeable membrane 45 by controlling the voltage applied to the anti-dazzle unit 4.
According to some embodiments of the present invention, the bezel area 444 is located on the upper side of the second substrate 442. Fig. 6 shows a front view of the rear view mirror 100 in the first state of the antiglare unit 4 when the bezel area 444 is formed on the upper side of the second substrate 442. By disposing the bezel area 444 on the upper side of the second substrate 442, the bezel width of the rear view mirror 100 can be visually reduced, optimizing the appearance of the rear view mirror 100.
According to some embodiments of the invention, the first mounting bracket 1 and the mounting bracket are integrally formed. For example, in some embodiments of the invention, the first mounting bracket 1 and the second mounting bracket 2 may be integrally injection molded. Therefore, the processing technology of the rearview mirror 100 can be simplified, the connection strength of the first mounting bracket 1 and the second mounting bracket 2 is improved, the cost of the rearview mirror 100 is reduced, and the structural strength of the rearview mirror 100 is improved.
