Specifically, referring to fig. 1 to 3, a stationary base 1 is provided on a vehicle body 20, a face recognition device 2 is provided on the stationary base 1 for recognizing a face of a driver, an illumination area at a human eye, and a hologram projection device 3 is provided on the stationary base 1 for projecting light onto at least one of a front windshield 201 and a side windshield 301 of the vehicle 100 to change the brightness of the front windshield 201 or the side windshield 301.

It can be appreciated that the fixing base 1 is the installation and the fixed basis of the face recognition device 2 and the holographic projection device 3, and the face recognition device 2 is provided with an intelligent recognition system, so that the face of a driver and the illumination area at the eyes can be recognized in real time, and whether the driving of the driver is influenced or not is judged by detecting whether sunlight can be irradiated to the eyes. The front windshield 201 and the side windshield 301 are photochromic glass, and the photochromic glass is glass having characteristics of absorbing light and darkening when light irradiation is performed, and fading and recovering light after the light irradiation is stopped, and when the hologram projection device 3 projects light onto at least one of the front windshield 201 and the side windshield 301 of the vehicle 100, the glass in the corresponding irradiated area changes color and darkens, thereby realizing the light blocking effect.

Meanwhile, compared with the light blocking realized by adopting a fixed sun shield, since the light blocking effect is realized by the fact that the holographic projection device 3 projects light to enable the photochromic glass to change color, the holographic projection device 3 can be arranged at one of a plurality of positions to project light on at least one of the front windshield 201 and the side windshield 301, so that the sun shield assembly 10 is flexibly arranged in the vehicle 100, the size of the sun shield assembly 10 is limited by a small space, the vehicle 100 of various vehicle types can be adapted under the condition that the size of the sun shield assembly 10 is not changed, and the adaptability is wide.

The holographic projection device 3 can only project light onto the side window glass 301, so that side light blocking is realized, light blocking on the front side can be avoided, sight of a driver is influenced, and driving safety is improved. Of course, the holographic projection device 3 can also project light onto the front windshield 201 and the side windshield 301 at the same time, thereby realizing front side and side light blocking, further improving the light blocking effect, and further improving the driving experience and driving safety of the driver. Different visor assemblies 10 may be customized depending on the needs of the user to achieve different light blocking requirements for front side light blocking, or both front and side light blocking. For example, in the example shown in fig. 2 and 3, the holographic projection device 3 may project onto the front windshield 201 and the side windshield 301 simultaneously.

In addition, the sun visor assembly 10 is provided in two, and can be provided at both the main driving and the co-driving places, whereby sunlight can be prevented from being irradiated from the side windshield 301 of the co-driving place to the face of the driver, further improving the light blocking effect, thereby improving the driving experience and driving safety of the driver, and at the same time, the riding experience of the passenger at the co-driving place can be improved.

According to the sun visor assembly 10 of the embodiment of the present invention, by providing the face recognition device 2 to recognize the face of the driver, the illumination area at the eyes, and providing the hologram projection device 3 for projecting light onto at least one of the front windshield 201 and the side windshield 301 of the vehicle 100 to change the shade of the front windshield 201 or the side windshield 301, different sun visor assemblies 10 can be customized according to the needs of the user, and different light blocking requirements of front side light blocking, or both front side and side light blocking can be achieved. At the same time, the sun visor assembly 10 is flexibly arranged in the vehicle 100, the size of the sun visor assembly 10 is limited by a small space, and the sun visor assembly 10 can be suitable for vehicles 100 of various vehicle types without changing the size of the sun visor assembly 10, and has wide adaptability.

In some embodiments of the present invention, as shown in fig. 2 and 3, the fixing base 1 has a receiving cavity 11, the receiving cavity 11 has an opening toward at least one of the front windshield 201 and the side windshield 301, the holographic projection device 3 is disposed in the receiving cavity 11, and light is emitted through the opening, and the holographic projection device 3 conforms to the shape of the receiving cavity 11, thereby allowing the holographic projection device 3 to be stably disposed in the receiving cavity 11, and improving structural stability.

In some embodiments of the invention, the holographic projection device 3 comprises a plurality of projection lamps, at least one of the angles and ranges of the light emitted by the plurality of projection lamps being different. It will be appreciated that the holographic projection device 3 may control the angle of the projected light by controlling the on-off of the different angle projection lamps, thereby changing the range and the projected position of the front windshield 201 and the side windshield 301 projected to the vehicle 100, thereby realizing real-time changing of the projected range and the projected position, thereby changing the color of the glass at the corresponding positions, thereby realizing flexible light blocking, and improving the light blocking effect. The projection lamp may be led (light-emitting diode) or the like.

When all the projection lamps in the holographic projection device 3 are turned on, the angle of the projection light is the largest, the range of the projection light to the front windshield 201 and the side windshield 301 of the vehicle 100 is the largest at this time, the range of the light blocking is also the largest, the angle of the projection light gradually decreases with the gradual turning off of the projection lamps at different angles, the range of the projection light to the front windshield 201 and the side windshield 301 of the vehicle 100 gradually decreases, and the range of the light blocking is also gradually decreased.

The front windshield 201 and the side windshield 301 are photochromic glass, and the photochromic glass is glass having characteristics of absorbing light and darkening when light irradiation is performed, and fading and recovering light after the light irradiation is stopped, and when the hologram projection device 3 projects light onto at least one of the front windshield 201 and the side windshield 301 of the vehicle 100, the glass in the corresponding irradiated area changes color and darkens, thereby realizing the light blocking effect. When the holographic projection device 3 stops working, the glass of the irradiated area is faded and is recovered, so that the normal driving of a driver is not influenced.

In some embodiments of the present invention, the roof 203 of the body 20 has a mounting slot thereon, and the stationary base 1 is rotatably provided on the roof 203 of the body 20 to switch between a first position located within the mounting slot and a second position located outside the mounting slot. It can be understood that the first position may be an initial position of the fixed base 1, where the light projected by the holographic projection device 3 cannot be projected onto the front windshield 201 or the side windshield 301, and the second position may be a working position of the holographic projection device 3, where the light projected by the holographic projection device 3 can be completely projected onto the front windshield 201 or the side windshield 301, where the complete projection means that all the projection lamps in the holographic projection device 3 are opened, and the light can completely cover the front windshield 201 or the side windshield 301 when the light is projected onto the front windshield 201 or the side windshield 301. Therefore, the fixed base 1 can be enabled to rotate within a certain range, and the fixed base 1 is prevented from rotating in disorder, so that the light blocking effect is improved.

It can be understood that when the sunlight sensor 202 senses that the sunlight is greater than or equal to the preset sunlight intensity, the driving motor 4 drives the fixing base 1 from the first position to the second position, the face recognition camera starts to recognize the face information, when the sunlight is recognized to be irradiated to the eyes, the holographic projection device 3 is controlled to project the angle of the light, the holographic projection device 3 projects the light to at least one of the front windshield 201 or the side windshield 301, so as to realize light blocking, when the sunlight sensor 202 senses that the sunlight is less than the preset sunlight intensity, the driving motor 4 drives the fixing base 1 from the second position to the first position, the holographic projection device 3 stops projecting the light, and the face recognition camera stops working, so that the light blocking mode is exited, and the driver is prevented from being influenced.

Therefore, the sunlight intensity is sensed in real time through the sunlight sensor 202, so that the work of the driving motor 4 is controlled, meanwhile, the work of the holographic projection device 3 and the face recognition camera is matched, the automatic intelligent light blocking effect is further realized, the light blocking effect is good, and the driving safety is improved.
