[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] Please refer to the following Figures 1 to 5 A camera device 1 , a camera and an interior rearview mirror installation assembly, and a vehicle according to an embodiment of the present invention are described.

[0030] like Figures 1 to 3As shown, the camera and interior rearview mirror installation assembly according to an embodiment of the present invention includes: a housing assembly 11 and an interior camera 12. The housing assembly 11 includes a base 111, a cover 112 and a light-transmitting plate 113. The base 111 is mounted on the front windshield 3. The cover 112 is mounted on the base 111 and defines a receiving cavity 114 with the base 111. The light-transmitting plate 113 is mounted on the cover 112. The interior camera 12 is mounted in the receiving cavity 114. The interior camera 12 includes a lens 121. The lens 121 is arranged toward the rear of the cover 112, and the lens 121 is opposite to the light-transmitting plate 113.

[0031] According to the camera device 1 of the embodiment of the present invention, since the inner camera 12 is installed in the accommodating cavity 114 surrounded by the base 111 and the cover, and the base 111 is installed on the front windshield 3, the distance between the inner camera 12 and the front passenger in the front-to-back direction can be increased, and the capture range of the inner camera 12 can be expanded. Since the cover 112 is provided with a light-transmitting plate 113 and the lens 121 is opposite to the light-transmitting plate 113, so that the lens 121 is hidden in the accommodating cavity 114, the integrity of the camera device 1 can be improved, and the lens 121 can be prevented from being scratched, the probability of damage to the lens 121 is reduced, and the subsequent maintenance cost is reduced.

[0032] In one example, the base 111 is used to install the interior rearview mirror 21. In other words, the interior camera 12 can be integrated with the interior rearview mirror 21 to reduce the space occupied by the installation assembly of the camera and the interior rearview mirror in the vehicle cabin.

[0033] For example, the base 111 has a flat surface on one side adjacent to the front windshield 3 , and the flat surface is bonded and fixed to the front windshield 3 to facilitate assembly of the camera device.

[0034] Optionally, the internal camera 12 can be installed on the base 111, or on the cover 112. For example, the internal camera 12 can be installed on the base 111 by a screw member, or on the cover 112 by a screw member.

[0035] In order to avoid interference or installation deviation between the lens 121 and the light-transmitting plate 113 after the internal camera 12 is installed, it is necessary to design a certain installation gap between the lens 121 and the light-transmitting plate 113. Figure 3 As shown, the distance between the lens 121 and the inner side surface of the light-transmitting plate 113 is L1, 0.5 mm ≤ L1 ≤ 1 mm. For example, L1 can be 0.5 mm, 0.7 mm, 0.8 mm, or 1 mm.

[0036] Optionally, the peripheral contour of the field of view of the lens 121 projected on the light-transmitting plate 113 is located within the peripheral contour of the light-transmitting plate 113, and the shortest distance between the peripheral contour of the field of view of the lens 121 projected on the light-transmitting plate 113 and the peripheral contour of the light-transmitting plate 113 is L2, 2mm≤L2≤5mm. It can be understood that the peripheral contour of the field of view of the lens 121 projected on the light-transmitting plate 113 is the framing range of the lens 121 at the position of the light-transmitting plate 113. In other words, the shortest distance between the framing range of the lens 121 at the position of the light-transmitting plate 113 and the peripheral contour of the light-transmitting plate 113 is L2, and L2 can be 2mm, 3mm, 4mm, or 5mm. The inventors of the present application have found through experimental research that when L2 adopts the above-mentioned numerical range, it can be ensured that after the lens 121 is installed, the light-transmitting plate 113 will not interfere with the framing of the lens 121, and the size of the light-transmitting plate 113 can be reduced.

[0037] Optionally, the light transmittance of the light-transmitting plate 113 is greater than or equal to 91%. Specifically, the light transmittance requirement of the light-transmitting plate 113 in the 940 wavelength band is greater than or equal to 91%. The implementation standard of the light transmittance of the light-transmitting plate 113 can be designed according to GT / B2410-2008, so that the camera device 1 has a better framing and imaging effect.

[0038] Optionally, the surface reflectivity of the light-transmitting plate 113 is less than or equal to 1%. The implementation standard of the surface reflectivity of the light-transmitting plate 113 can be designed according to ASTM F1252-2016, so that the camera device 1 has a better framing and imaging effect.

[0039] For example, Figure 1 As shown, the light-transmitting plate 113 is generally rectangular, and the length of the light-transmitting plate 113 is consistent with the length direction of the vehicle. In one example, the width of the light-transmitting plate 113 is between 25 mm and 30 mm, and the length of the light-transmitting plate 113 is between 110 mm and 120 mm. It is understood that the light-transmitting plate 113 can also be other shapes, and this application does not limit this.

[0040] In some embodiments, Figure 3 As shown, the internal camera 12 further includes a fill light 122 and a stopper 123, at least part of the stopper 123 is disposed between the fill light 122 and the lens 121, and the fill light 122 is opposite to the light-transmitting plate 113. It can be understood that the fill light 122 can be used for fill light when the lens 121 is shooting, and the stopper 123 can block the interference of the light of the fill light 122 on the shooting of the lens 121, thereby improving the imaging effect of the lens 121.

[0041] Alternatively, if Figure 3As shown, the stopper 123 is arranged circumferentially around the lens 121. It is understandable that the stopper 123 is generally a closed annular structure and is arranged circumferentially around the lens 121, thereby further blocking the interference of the light of the fill light 122 on the camera of the lens 121 and improving the imaging effect of the lens 121.

[0042] Alternatively, if Figure 4 As shown, there are at least two lenses 121, and the two lenses 121 are respectively installed on opposite sides of the fill light 122. In one example, there are two lenses 121, and the fill light 122 is installed in the middle of the two lenses 121. The two lenses 121 are arranged at intervals along the length direction of the light-transmitting plate 113, so that the structure of the inner camera 12 can be compact and the fill light effect is better.

[0043] Alternatively, if Figure 4 and Figure 5 As shown, the internal camera 12 further includes ear seats 124, at least two ear seats 124 are arranged on opposite sides of the lens 121, and the ear seats 124 are connected to at least one of the base 111 and the cover 112 through screws. Specifically, there are two ear seats 124 and they are arranged on the left and right sides of the lens 121, and the ear seats 124 are connected to the cover 112 through screws.

[0044] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the cover 112 includes a first cover 1121 and a second cover 1122, the first cover 1121 is installed on the base 111, the second cover 1122 is installed on the first cover 1121, the light-transmitting plate 113 is installed on the second cover 1122, the first cover 1121, the second cover 1122 and the base 111 form a accommodating cavity 114, it can be understood that the first cover 1121, the second cover 1122 and the base 111 can be detachably connected, so as to facilitate the processing and manufacturing of the cover 112 and the base 111.

[0045] Optionally, the cover 112 is provided with a mounting opening 1123 for passing the bracket of the inner rearview mirror 21, part of the mounting opening 1123 is provided on the first cover 1121, and the other part of the mounting opening 1123 is provided on the second cover 1122. That is, the first cover 1121 is provided with a semicircular hole, the second cover 1122 is provided with a semicircular hole, and the two semicircular holes are spliced ​​to form the mounting opening 1123. It can be understood that the mounting opening 1123 is installed at the splicing position of the first cover 1121 and the second cover 1122, so when disassembling the first cover 1121, the second cover 1122 or the inner camera 12, it is not necessary to remove the inner rearview mirror assembly 2, thereby facilitating the installation and disassembly of the camera device 1.

[0046] Alternatively, if Figure 2 , Figure 4and Figure 5 As shown, one of the first cover 1121 and the second cover 1122 is provided with a first clamping column 11221, and the other is provided with a first matching hole 11211, and the first clamping column 11221 is clamped with the first matching hole 11211. Specifically, the first cover 1121 is provided with the first matching hole 11211, and the second cover 1122 is provided with the first clamping column 11221, and the first clamping column 11221 and the first matching hole 11211 are both multiple and one-to-one corresponding, so as to facilitate the disassembly and assembly of the first cover 1121 and the second cover 1122, and improve the stability of the installation of the first cover 1121 and the second cover 1122.

[0047] Furthermore, if Figure 5 As shown, the first cover 1121 is provided with an opening, and the outer edge of the opening has a snap-fit ​​groove 11212 in the circumferential direction. The snap-fit ​​edge of the second cover 1122 is inserted into the snap-fit ​​groove 11212 to improve the aesthetics and sealing effect of the connection position between the first cover 1121 and the second cover 1122.

[0048] Alternatively, if Figure 2 , Figure 4 and Figure 5 As shown, one of the base 111 and the first cover 1121 is provided with a second clamping column 11213, and the other is provided with a second matching hole, and the second clamping column 11213 is clamped with the second matching hole (not shown). Specifically, the base 111 is provided with a second matching hole, and the first cover 1121 is provided with a second clamping column 11213, and the second clamping column 11213 and the second matching hole are both multiple and one-to-one corresponding, so as to facilitate the disassembly and assembly of the base 111 and the first cover 1121, and can improve the stability of the installation of the base 111 and the first cover 1121.

[0049] Alternatively, if Figure 3 As shown, the second cover 1122 is provided with a mounting hole 11222, and the outer periphery of the light-transmitting plate 113 is engaged with the inner periphery of the mounting hole 11222. For example, the outer periphery of the light-transmitting plate 113 is provided with a hook 1131, and the hook 1131 is engaged with the inner periphery of the mounting hole 11222. In other embodiments, the light-transmitting plate 113 can also be bonded, welded, or connected to the second cover 1122 by screws.

[0051] According to the camera and interior rearview mirror installation assembly of the embodiment of the present invention, since the interior camera 12 is installed in the accommodating cavity 114 surrounded by the base 111 and the cover, and the base 111 is installed on the front windshield 3 and is used to install the interior rearview mirror 21, the interior camera 12 and the interior rearview mirror 21 can be integrated to increase the distance between the interior camera 12 and the front passenger in the front and rear directions, and expand the capture range of the interior camera 12. In addition, since the cover 112 is provided with a light-transmitting plate 113 and the lens 121 is opposite to the light-transmitting plate 113, so that the lens 121 is hidden in the accommodating cavity 114, the integrity of the camera device 1 can be improved, and the lens 121 can be prevented from being scratched, and the probability of damage to the lens 121 is reduced.
