The light absorption sheet 130 is disposed on the side of the reflection sheet 120 away from the front case 111, and the side of the light absorption sheet 130 having a flexible material is close to the reflection sheet 120 and a gap 133 is reserved with the reflection sheet 120 (refer to FIG. 4); the driving component 140 and light absorption The side of the sheet 130 away from the reflective sheet 120 is connected. The reflectivity of the reflective sheet 120 is greater than the reflectivity of the light absorbing sheet 130. When in use, the driving component 140 is configured to push the light absorbing sheet 130 to adhere to the reflective sheet 120.

In this embodiment, the front case 111 may be a hollow frame case, and the front case 111 may fix the reflecting sheet 120 and leave the reflecting sheet 120 exposed from the hollowed portion to serve as a reflecting mirror surface capable of receiving and reflecting light.

In this embodiment, the reflection sheet 120 may be formed of a transparent material, for example, the reflection sheet 120 may be formed of a material such as glass, transparent resin, or the like. The reflective sheet 120 can transmit light. When the first surface of the reflective sheet 120 is in a strong light environment and the second surface of the reflective sheet 120 is in a weak light environment, the first surface can be used as a reflective surface to reflect light in a strong light environment. To use as a mirror. The rear case 112 may be made of a non-transparent material, such as black plastic, so that one side of the reflection sheet 120 in the cavity 180 is in a low-light environment.

In this embodiment, the light absorbing sheet 130 can absorb at least part of the light transmitted through the reflective sheet 120. The flexible material constituting the light absorbing sheet 130 may include materials such as flexible black glue or flexible gray glue.

Optionally, the light absorption sheet 130 includes a soft light absorption layer 131 formed of a flexible material (flexible black glue or flexible gray glue, etc.) and a fixing sheet 132 formed of a magnetic conductive material. The soft light absorbing layer 131 is disposed on the fixing sheet 132, and the magnet 141 is provided on a side of the fixing sheet 132 away from the soft light absorbing layer 131. The side of the soft body light absorbing layer 131 that is far from the fixing sheet 132 can be attached to the reflecting sheet under the driving force of the driving component 140. The soft light absorbing layer 131 is flexible and can deform to a certain extent, which helps to adhere to the reflecting sheet 120.

Please refer to FIGS. 5 to 8 in combination, wherein FIG. 5 is a schematic structural diagram of the reflection sheet 120 and the light absorption sheet 130 in the first state in the mirror device 100 according to the embodiment of the present disclosure, and FIG. 6 is shown in FIG. 5. A partially enlarged schematic diagram of a part I, FIG. 7 is a schematic structural diagram of the reflection sheet 120 and the light absorption sheet 130 in the second state in the mirror device 100 according to an embodiment of the present disclosure, and FIG. 8 is a partially enlarged diagram of a part II shown in FIG. 7 schematic diagram. Optionally, the mirror device 100 further includes an elastic member 150. One end of the elastic member 150 is connected to a side of the light absorbing sheet 130 near the front case 111, and the other end of the elastic member 150 is connected to the front case 111. When there is no glare effect, the elastic member 150 is configured to support the light absorbing sheet 130 so that a certain gap 133 is formed between the light absorbing sheet 130 and the reflective sheet 120. The width of the gap 133 can be set according to the actual situation. The sheet 120 and the light absorbing sheet 130 are in a first state. In the first state, since the side of the reflecting sheet 120 near the rear case 122 is not in contact with the light absorbing sheet 130, it is exposed to the air inside the cavity, that is, the reflecting sheet 120 can reflect more light, and Less light passes through the reflective sheet 120.

When glare occurs, the driving component 140 is activated, the driving component 140 works to push the light absorbing sheet 130, and the elastic member 150 is compressed during the movement of the light absorbing sheet 130. When the light absorbing sheet 130 moves until the light absorbing sheet 130 is closely attached to the reflection sheet 120, At this time, the reflection sheet 120 and the light absorption sheet 130 may be said to be in a second state. Compared with the first state, in the second state, since the side of the reflection sheet 120 near the rear case 122 is in contact with the light absorption sheet 130, the light absorption sheet 130 can absorb more light in the second state, so that the reflection sheet 120 Less light can be reflected, reducing glare effects. When the glare effect disappears, the driving assembly 140 returns to the original state, that is, the state where the reflecting sheet 120 and the light absorption sheet 130 are in the first state. When the driving assembly 140 is in this state, the driving assembly 140 is applied to the light absorption sheet. The thrust force on 130 is reduced, that is, the thrust force received by the elastic member 150 is reduced. The elastic member 150 releases the elastic potential energy, so that the light absorption sheet 130 is separated from the surface of the reflection sheet 120, and there is a gap 133 between the light absorption sheet 130 and the reflection sheet 120. This contributes to miniaturization of the volume of the mirror device 100.

At least two latching openings 192 are arranged at intervals along the circumferential direction of the front shell. The front shell is inserted into the rear shell through the plug portion 011 and at least two latching protrusions 191 correspond to the at least two latching openings 192 one-to-one. Card access.

Please refer to FIG. 1 again, the reflection device provided by the embodiment of the present disclosure may further include a bracket 160. The bracket 160 is disposed on an end of the rear case 112 away from the front case 111. In this embodiment, the bracket 160 and the rear shell 112 can be rotatably connected, for example, connected with a ball hinge structure, so that the rear shell 112 can rotate around the bracket 160, thereby changing the angle of the reflection sheet 120. The other end of the bracket 160 may be disposed on the vehicle. For example, when used as a rearview mirror of a vehicle, an end of the bracket 160 away from the rear case 112 may be fixed to the vehicle.

In other embodiments, the driving assembly 140 may include a motor 143, a lead screw 144, and a slider 145. The motor 143 drives and connects the lead screw 144. The slider 145 is screwed outside the lead screw 144.

By controlling the rotation direction of the motor 143, the slider 145 is moved closer to the reflective sheet 120 or moved away from the reflective sheet 120, so that the light absorption sheet 130 is moved closer to the reflection sheet 120 to fit on the reflection sheet 120 or the light absorption sheet 130 is separated from the reflection sheet 120 and It is spaced from the reflection sheet 120. The motor 143 is connected to the processing module 171, and the processing module 171 controls startup, shutdown, rotation speed and steering of the motor 143.

Please refer to FIG. 10, which is one of schematic circuit diagrams of a mirror device 100 according to an embodiment of the present disclosure. In this embodiment, the mirror device 100 may further include a processing module 171. A first photosensitive sensor 172 connected to the processing module 171 is provided on the front case 111, and a second photosensitive sensor connected to the processing module 171 is provided on the rear case 112. The sensor 173; the driving assembly 140 includes a magnet 141 and an electromagnet 142 connected to the processing module 171. The magnet 141 is disposed on a side of the light absorption sheet 130 away from the front case 111, the electromagnet 142 is disposed on the rear case 112, and one magnetic pole of the magnet 141 Orienting the electromagnet 142, in use, when the two magnet poles of the electromagnet 142 and the magnet 141 are close to each other when in use, the electromagnet 142 can push the magnet 141 to move, so as to push the light absorbing sheet 130 to be attached to the reflective sheet 120.

In this embodiment, the processing module 171 may be an integrated circuit chip and has a signal processing capability. The processing module 171 may be a general-purpose processor. For example, the processor may be a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), or a Network Processor (NP); the processing module 171 may also be digital signal processing Device (DSP), application specific integrated circuit (ASIC), field programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component. Of course, the processing module 171 may also be a single-chip microcomputer (MCU), such as an SMT32 series single-chip microcomputer.

In this embodiment, the first photosensor 172 may be configured to collect a first light intensity directed toward the front case 111, and the second light sensor 173 may be configured to collect a second light intensity directed toward the rear case 112. The processing module 171 may be configured to compare the first light intensity and the second light intensity. The processing module 171 may be configured to generate a control signal when a glare effect is determined to occur. For example, when the own vehicle is in a dark environment or a weak light environment, and the rear vehicle has light shining on the reflection sheet 120, the processing module 171 generates a control signal, and the driving component 140 pushes the light absorption sheet 130 to fit the reflection according to the control signal. Tablet 120. For example, the processing module 171 controls the electromagnet 142 to be energized based on the control signal (the first control signal), so that the magnetic poles of the two ends of the electromagnet 142 and the magnet 141 are the same, so as to generate a repulsive thrust, thereby pushing the light absorption sheet 130 to be attached. The reflection sheet 120 achieves the purpose of reducing the influence of glare.

When the glare effect disappears, the processing module 171 may generate another control signal (second control signal), so that the electromagnet 142 is powered off, the repulsive force of the two ends close to the magnet 141 is weakened or disappeared, and the elastic member 150 is released. With elastic potential energy, the light absorption sheet 130 is separated from the surface of the reflection sheet 120 so that there is a gap 133 between the light absorption sheet 130 and the reflection sheet 120. Of course, when the glare effect disappears, the processing module 171 may control the electromagnet 142 to generate a magnetic field opposite to the first control signal based on the second control signal, that is, the magnetic poles at the two ends close to the electromagnet 142 and the magnet 141 are different. The magnetic force attracted by the electromagnet 142 and the magnet 141 is generated, so that the light absorption sheet 130 is separated from the surface of the reflection sheet 120, so that there is a gap 133 between the light absorption sheet 130 and the reflection sheet 120.

Specifically, when the processing module 171 detects that the first light intensity is greater than or equal to the first threshold value and the second light intensity is less than or equal to the second threshold value, the processing module 171 generates a control signal, where the first threshold value is greater than the second threshold value, and the first Both the first threshold and the second threshold can be set according to actual conditions, and are not specifically limited here. The numbers of the magnets 141 and the electromagnets 142 can be set according to actual conditions. Optionally, the number of the magnets 141 and the number of the electromagnets 142 can be at least two, at least two of the magnets 141 and at least two of the electromagnets 142. One-to-one correspondence constitutes a group.
