[0031] Specifically, during use, camera component 20 is integrated inside casing 10, so that camera component 20 does not leak out, making the entire rearview mirror more concise, and also ensuring that camera component 20 is not disturbed by the external environment, so that the state of the driver in the cab can be normally monitored, so that the driving state of the driver can be monitored in real time by the background system, and the driving safety is improved.

[0032] In addition, since display screen 31 and backlight module 32 are fully pasted, the intensity and uniformity of the backlight can be controlled by backlight module 32, so that the bright part in the displayed image in display screen 31 is brighter, and the dark part is darker, so that the details in the display image are more prominent, the image on the screen is clear and visible, and the user experience is improved.

[0033] It should be noted that casing 10 in the embodiment can be formed by a plurality of shells, so that first installation cavity 111 and second installation cavity 112 are formed inside casing 10 to install display component 30 and camera component 20, and the bracket 50 on the casing can be connected to the vehicle body after assembly is completed; of course, the two installation cavities in different positions can also be integrally formed inside casing 10, and display component 30 can be connected to the two installation cavities of casing 10 by clamping, gluing or connecting pieces (such as screws or bolts, etc.

[0034] More specifically, in the embodiment, the display screen 31 and the backlight module 32 are filled with an optical transparent adhesive (such as OCA adhesive or OCA adhesive film) between them when assembled, to fill the small gap between them, so that the display screen 31 and the backlight module 32 are tightly attached, realizing seamless connection, effectively reducing the reflection and scattering of light at the interface, improving the transmittance and transmission efficiency of light, thereby improving the brightness and contrast of the display screen 31, making the display picture clearer and brighter.

[0035] Further, the light supplement assembly is also included, which comprises at least two lamp beads 43 and a lamp bead 43 circuit board, the lamp bead 43 circuit board is located in the first mounting cavity 111 or the second mounting cavity 112, and each two lamp beads 43 are symmetrically distributed on both sides of the lamp bead 43 circuit board and are used for releasing light.

[0036] Specifically, when the vehicle drives in a dark environment such as night, tunnel or underground parking lot, the picture taken by the camera assembly 20 is easy to become dim, which affects the observation of the driver, so the light released by the plurality of lamp beads 43 in the embodiment supplements light for the camera assembly 20, so that the picture taken by the camera assembly 20 is brighter and the details are clearer, so that the system can clearly identify the driving state of the driver to accurately monitor the driving state, thereby greatly improving the driving safety.

[0037] More specifically, since each two lamp beads 43 are symmetrically distributed on both sides of the lamp bead 43 circuit board, the light released by the lamp beads 43 on both sides is uniformly distributed in the field of view of the camera assembly 20, avoiding the occurrence of local over-bright or over-dark areas in the field of view of the camera assembly 20, so that the brightness of the entire picture is more balanced.

[0038] As a preferred, the lamp beads 43 in the embodiment can adopt infrared lamp beads, infrared light can provide illumination in a completely dark environment and can be captured by the image sensor of the camera, most of the image sensors of the camera have a certain response ability to infrared light and can image by using infrared light reflection, so that even in the absence of visible light, the infrared light emitted by the infrared lamp beads irradiates the object, and the infrared light reflected by the object is received by the image sensor, so that the camera can clearly "see" the object in the dark environment, providing more effective image information for monitoring.

[0039] In addition, even in an environment with some light, the light released by the plurality of lamp beads 43 can enhance the contrast of the picture, making the outline of the object more distinct, and further improving the clarity of the picture.

[0040] Further, the camera assembly 20 comprises the camera 21, the camera circuit board 22 and the mounting base 23, the mounting base 23 is provided with a through slot 231, the camera 21 is arranged in the through slot 231, the camera circuit board 22 is capped at one end of the through slot 231 away from the camera 21 and is electrically connected with the camera 21, and the lamp bead 43 circuit board is located in the first mounting cavity 111.

[0041] On the basis of the structure, during assembly, the camera 21 is arranged in the through slot 231, then is electrically connected with the camera circuit board 22, finally the mounting base 23 is fixed in the first mounting cavity 111 by gluing, embedding or through a connecting member (such as a screw or a bolt, etc.), so as to fix the camera assembly 20 through the mounting base 23, facilitating assembly, and the camera 21 and the camera circuit board 22 are also more stable after being mounted.

[0042] As preferred, in the embodiment, the lamp bead 43 circuit board is located in the first mounting cavity 111, so that the light emitted by the plurality of lamp beads 43 on the lamp bead 43 circuit board irradiates the inside of the first mounting cavity 111, which is more conducive to light compensation of the camera 21, so that the picture captured by the camera 21 is clearer.

[0043] It should be noted that the camera circuit board 22 in the embodiment is used to convert the optical signal of the lens into an electrical signal, then transmit to the control circuit board 33 in the rearview mirror, and convert the electrical signal into a picture on the display assembly 30 through the control circuit board 33.

[0044] More specifically, the middle part of the lamp bead 43 circuit board in the embodiment is provided with a bayonet 41, during assembly, the lamp bead 43 circuit board is clamped to the outer periphery of the camera 21 through the bayonet 41, so that the plurality of lamp beads 43 uniformly distributed on both sides of the lamp bead 43 circuit board can be uniformly distributed on both sides of the camera 21, so that the light is uniformly distributed in the field of view of the camera 21, avoiding the occurrence of local over-bright or over-dark areas in the field of view of the camera 21, so as to make the brightness of the entire shooting picture more balanced, reduce the possible aberration, chromatic aberration and other problems of the camera 21 under non-uniform light, thereby improving the resolution and color restoration degree of the image, and making the picture captured by the camera 21 more accurately reflect the actual situation.

[0045] Further, the camera assembly 20 further comprises a light blocking ring 24, the light blocking ring 24 is sleeved on the outer periphery of the camera 21.

[0046] Specifically, due to the reflection of light from various directions into the camera 21 in various environments, such as outdoor on a sunny day or in a place with strong light, the stray light may reduce the contrast and clarity of the image, and thus in the embodiment, the light blocking ring 24 is arranged on the outer periphery of the camera 21, and the light blocking ring 24 effectively blocks the light in the non-imaging light path, reduces the interference of stray light in the surrounding environment to the camera 21, makes the subject of the shot more prominent, and the cluttered light in the background is suppressed, thereby improving the image quality.

[0047] It should be noted that the light blocking ring 24 can be made of aluminum alloy, stainless steel, or plastic (such as polycarbonate (PC)) having certain strength or hardness. When assembled, the light blocking ring 24 can be arranged on the outer periphery of the camera 21 by means of gluing, clamping, or connecting through a connecting piece, so that the outer periphery of the camera 21 forms a light shielding wall with a certain height and angle, allowing only light within a certain angle range in front of the lens to enter, thereby blocking stray light from other directions.

[0048] More specifically, the outer periphery of the camera 21 in the embodiment is provided with a limiting groove 211, which extends along the circumference of the camera 21. When assembled, the outer periphery of the light blocking ring 24 is embedded into the limiting groove 211, so that the light blocking ring 24 is limited by the groove wall of the limiting groove 211, and the light blocking ring 24 is not easy to come off after being assembled with the camera 21, and the structure is more stable.

[0049] Further, the through slot 231 is a threaded slot, and the camera 21 is provided with threads on the outer periphery. When assembled, the threads on the outer periphery of the camera 21 are screwed with the threaded slot to make a threaded connection. The threaded connection can provide strong engagement force and friction force, making the connection between the camera 21 and the mounting seat 23 more secure.

[0050] Compared with some simple buckle type or plug-in type connection, threaded connection can better resist external interference such as vibration and impact, reducing the risk of displacement or falling of the camera 21 due to loose connection, and ensuring that the camera 21 maintains a stable working state during long-term use.

[0051] It should be noted that the camera 21 in the embodiment can be a conventional threaded camera 21, so that the camera 21 is integrally formed with threads on the outer periphery.

[0052] Further, it further includes a cover plate 34 made of transparent material and used for covering the shell 10.

[0053] Specifically, when the camera assembly 20 and the display assembly 30 are respectively installed in the first installation cavity 111 and the second installation cavity 112, the cover plate 34 is connected to the periphery of the shell 10 by means of gluing, welding or connecting through a connecting piece, so that the cover plate 34 covers the first installation cavity 111 and the second installation cavity 112. Since the cover plate 34 is made of transparent material, the display assembly 30 and the camera assembly 20 can be normally used after the cover plate 34 covers the shell 10, and are not easily affected by the external environment.

[0054] As preferred, the cover plate 34 in the embodiment can be made of existing glass or transparent plastic or other transparent materials.

[0055] Further, at least one heat dissipation piece is further included, and the at least one heat dissipation piece is used to dissipate heat for the first installation cavity 111 or the second installation cavity 112.

[0056] Specifically, since the display assembly 30, the camera assembly 20 and the light supplement assembly all generate heat during use, which causes the first installation cavity 111 or the second installation cavity 112 to overheat and damage the internal structure, the heat dissipation piece is arranged to dissipate heat. During assembly, the heat dissipation piece can be arranged in multiple, and then the heat-dissipating modules (such as the control circuit board 33, the camera circuit board 22 or the circuit board of the lamp bead 43) in the display assembly 30 are attached to dissipate heat for the heat-dissipating modules.

[0057] As preferred, the heat dissipation piece can be made of an existing aluminum alloy heat dissipation plate or a copper heat dissipation plate, and the heat dissipation piece is attached to the heat-dissipating modules to dissipate heat.

[0058] Further, the shell 10 is provided with an installation frame 11, the installation frame 11 is detachably connected with the shell 10, and the first installation cavity 111 and the second installation cavity 112 are arranged on the installation frame 11.
