DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0060] The camera device provided by the embodiment of the utility model is applied to a passenger monitoring system of a vehicle, such as Figure 1 As shown, it includes: a camera body 7 and a camera light shield 31 arranged on the camera body 7, and the camera device also includes a light blocking component;

[0061] The light blocking component is arranged on the camera hood 31 to block the upward field of view of the fill light of the camera body 7 .

[0062] It should be noted that the structure of the camera shading cover 31 can be referred to Figure 7 as shown; Figure 1 As shown, the camera hood 31 is assembled and connected with the camera body 7 by buckles, that is, the camera hood 31 is assembled with the camera body 7 by buckles to form a camera; Fig. 9As shown, the fill light of the camera body 7 is an IR-LED 33 (infrared LED light); the light blocking component can be set on the back (inside) or front (outside) of the camera hood 31, and is used to block the upward field of view of the fill light of the camera body 7, that is, to block the upper part of the field of view of the fill light of the camera body 7, to prevent the light of the fill light from shining on the ceiling position in the cabin, that is, to prevent the light of the fill light from shining on the ceiling and reading light in the cabin, to avoid overexposure of the picture, to ensure the imaging quality of the camera device, that is, to ensure that the picture will not be overexposed during night imaging of the camera device. It can be seen that, based on the camera of the original passenger monitoring system, this solution adds a light blocking component to the camera hood 31, which is used to block the field of view (light) of the fill light of the camera body 7 toward the ceiling in the cabin, to prevent the light of the fill light from shining on the ceiling and reading light position in the cabin, to avoid overexposure of the picture, to ensure the imaging quality of the camera device.

[0063] It can be seen from the above technical solution that the camera device provided by the embodiment of the utility model, by adding a light blocking component on the camera hood, is used to block the field of view of the fill light of the camera body toward the ceiling in the cabin, thereby preventing the light of the fill light from shining on the ceiling in the cabin and the position of the reading light, avoiding overexposure of the picture, ensuring the imaging quality of the camera device, and ensuring normal recognition of the passenger monitoring system.

[0064] In this solution, the light blocking component includes:

[0065] The light shield is arranged on the back of the camera visor 31 and located in front of the fill light. Figure 7 As shown, the light shield is arranged inside the camera shading cover 31 and is located above and in front of the fill light, so as to facilitate shielding of the upper part of the field of view of the fill light. Fig. 9 As shown. The number of fill lights of the camera body 7 is two, that is, the number of IR-LEDs 33 is two, and they are distributed on both sides of the lens of the camera body 7; in order to achieve the shielding of the upper part of the field of view of the two fill lights, accordingly, as shown Figure 7 As shown, the light shield includes: a first light shield 4 and a second light shield 5; the first light shield 4 and the second light shield 5 are respectively arranged on the back of the camera hood 31, and are located one by one in front of the two fill lights. That is to say, based on the camera of the original passenger monitoring system, this solution adds a light shield inside the camera hood 31 for the upward field of view of each fill light, so as to prevent the light of any fill light from shining on the ceiling and the reading light position in the cabin, thereby ensuring the imaging quality of the camera device. In addition, Figure 7 As shown, the first light blocking sheet 4 and the second light blocking sheet 5 are both square light blocking sheets.

[0066] Specifically, the light shielding sheet includes:

[0067] The foam is pasted on the back of the camera hood 31. That is, by pasting the foam (film) on the inside of the camera hood 31 and the position corresponding to the front and upper part of the fill light, the fill light is prevented from hitting the ceiling and the reading light, ensuring that the image will not be overexposed during nighttime imaging of the camera device; of course, the light shielding component adopts this light shielding method, which has the characteristics of simple structure and convenient setting. In addition, the foam can be black foam.

[0068] Furthermore, if Figure 1 As shown, the camera device provided by the embodiment of the utility model further includes: a shielding shell 3 and a baffle 1;

[0069] The shielding shell 3 is used to be arranged in a cabin of a vehicle and has an opening;

[0070] like Fig.12 As shown, the camera body 7 and the camera hood 31 are both disposed in the shielding shell 3, and the camera hood 31 is aligned with the opening of the shielding shell 3;

[0071] The baffle 1 can open and close an opening provided in the shielding housing 3 .

[0072] It should be noted that the shielding shell 3 can be set on the mounting cover of the rearview mirror in the cabin, and is installed facing the passengers; the camera consisting of the camera body 7 and the camera hood 31 is set in the shielding shell 3, and the camera hood 31 is aligned with the opening of the shielding shell 3 to ensure that the camera is not blocked; the baffle 1 can be opened and closed at the opening of the shielding shell 3 to achieve the effect of opening and closing the opening of the shielding shell 3. Among them, when the camera works normally during the day, the opening of the shielding shell 3 needs to be in an open state, such as Fig.16 As shown, the baffle 1 does not need to cover the opening of the shielding shell 3; when the red exposure phenomenon of the IR-LED of the night camera is too obvious and causes discomfort to the passengers and the driver, the opening of the shielding shell 3 needs to be in a closed state, such as Figure 2 As shown, the baffle 1 needs to cover the opening of the shielding shell 3 to prevent the red exposure phenomenon of the camera from appearing in the field of vision of the passengers and the driver, and to prevent the passengers and the driver from feeling monitored. In other words, this solution adds an openable and closable shielding mechanism to the camera, so that when the camera works in the IR mode at night, the red exposure phenomenon can be prevented from appearing in the field of vision of the passengers and the driver, avoiding the discomfort of the passengers and the driver being monitored, thereby protecting the privacy of the passengers and the driver.

[0073] Furthermore, if Figure 1 As shown, the opening of the shielding shell 3 is located at the first side of the shielding shell 3;

[0074] like Figure 4 As shown, slide grooves 20 are respectively provided on both sides of the opening of the shielding shell 3;

[0075] The shielding shell 3 is provided with a slot penetrating the opening and the slide grooves 20 on both sides thereof;

[0076] The baffle plate 1 is used to be inserted into the slot and can slide along the slide grooves 20 on both sides of the opening to close the opening of the shielding housing 3 .

[0077] It should be noted that the first side portion of the shielding shell 3 may be the front side portion of the shielding shell 3; accordingly, Figure 4 As shown, the left and right sides of the opening of the shielding shell 3 can be respectively provided with slide grooves 20 in the vertical direction, that is, the slide grooves 20 are vertical slide grooves; the top or bottom of the shielding shell 3 is provided with the above-mentioned slots, so that the baffle 1 can be inserted into the slide grooves 20 on both sides of the opening from the top or bottom of the shielding shell 3 (such as Fig.11 As shown), the shielding shell 3 opening is closed. That is to say, the baffle 1 of the present solution can be detachably slidably arranged in the slide grooves 20 on both sides of the shielding shell 3 opening, that is, the baffle 1 adopts a sliding manner to realize the convenient opening and closing of the shielding shell 3 opening. Of course, the baffle 1 can also adopt other opening and closing methods, such as flip opening and closing, which will not be repeated here.

[0078] In this scheme, if Fig.15 As shown, the slide 20 includes: an inner slide and an outer slide arranged adjacent to each other;

[0079] The slot is opened at the bottom of the shielding shell 3, such as Fig.11 As shown, the baffle 1 is inserted from the bottom of the shielding shell 3 into the slide grooves 20 on both sides of the opening;

[0080] like Figure 4 As shown, the top of the shielding shell 3 is provided with a through groove 38 penetrating the opening and the outer grooves on both sides thereof, and a first groove 14 penetrating the through groove 38 is provided, and the top of the inner groove is higher than the bottom of the first groove 14; wherein the first groove 14 of the shielding shell 3 is the upper groove of the shielding shell 3;

[0081] like Figure 5 As shown, the bottom ends of both sides of the baffle 1 are respectively provided with a rotating shaft 28, and can slide along the inner slide grooves on both sides of the opening to its top and rotate to a horizontal position, so that the baffle 1 is received in the first groove 14 of the shielding shell 3. Figure 5 As shown, the rotating shafts 28 at the bottom ends of both sides of the baffle 1 are round pins respectively arranged at the bottom ends of both sides of the baffle 1.

[0082] It should be noted that if Fig.15As shown, the slide groove 20 on each side of the opening of the shielding shell 3 includes: an inner slide groove and an outer slide groove arranged adjacent to each other; wherein, the two sides (such as the left and right sides) of the baffle 1 can slide along the outer slide grooves on both sides of the opening respectively; of course, in this process, the rotating shafts 28 on both sides of the baffle 1 can also slide and rotate along the inner slide grooves on both sides of the opening respectively, especially when sliding to the top of the inner slide grooves on both sides of the opening (such as Fig.16 As shown), the baffle 1 can be rotated to a horizontal position so that the baffle 1 is horizontally received in the first groove 14 of the shielding shell 3 (as shown in FIG. Fig.17 As shown), the baffle 1 can be flipped and stored to avoid the baffle 1 occupying the space in the cabin. That is to say, the two sides of the baffle 1 are used to match the outer slide grooves on the two sides of the opening one by one, and the rotating shafts 28 on the two sides of the baffle 1 are used to match the inner slide grooves on the two sides of the opening one by one; in addition, the top of the shielding shell 3 is respectively provided with a through groove 38 and a first groove 14, and the top of the inner slide groove is designed at a high position, which is to ensure that when the rotating shafts 28 on both sides of the baffle 1 slide to the top of the inner slide grooves on both sides of the opening, they can be rotated to a horizontal position and stored in the first groove 14.

[0083] Specifically, Fig.11 As shown, the bottom of the shielding shell 3 is provided with a first card slot 39 penetrating the first side portion, the opening and the slot thereof;

[0084] like Fig.11 As shown, a limiting boss 16 is provided at the lower part of the middle part of the baffle 1, and can pass through the first clamping groove 39; wherein, the limiting boss 16 is provided at the bottom end of the middle part of the baffle 1 (positive part), and can pass through the first clamping groove 39 during the process of the baffle 1 sliding upward along the slide grooves 20 on both sides of the opening, so as to avoid sliding interference of the baffle 1;

[0085] like Figure 1 As shown, the camera device further includes a first buckle 2;

[0086] like Figure 2 As shown, when the baffle 1 is closed, the first buckle 2 is detachably engaged with the first slot 39, and the limiting boss 16 of the baffle 1 contacts and cooperates with the first buckle 2 up and down, thereby achieving the lower limit of the baffle 1 and preventing the baffle 1 from falling off after closing. Of course, the first buckle 2 is also equivalent to a limiting block that is engaged with the first slot 39 and contacts and cooperates with the bottom of the limiting boss 16.

[0087] Furthermore, if Fig.11 As shown, the first side portion of the shielding shell 3 is provided with a first latch hole and a second latch hole, and they are respectively located on both sides of the first card slot 39. The first latch hole is a latch through hole, and can be distributed on the right side of the first card slot;

[0088] The first buckle 2 is provided with a third latch hole, and when the first buckle 2 is engaged with the first slot 39, the first latch hole, the third latch hole and the second latch hole are collinearly distributed; wherein the three latch holes are all arranged along the left and right horizontal directions of the opening;

[0089] like Figure 1 As shown, the camera device further includes a latch 13;

[0090] When the first buckle 2 is engaged with the first slot 39, the latch 13 is used to be inserted into the first latch hole, the third latch hole and the second latch hole in sequence, so that the first buckle 2 can achieve a locking effect. Figure 6 As shown, the latch 13 includes: a latch body 29 and a latch head 30 arranged at one end of the latch body 29, and the latch body 29 is provided with a rotation-stopping edge along the axial direction on at least one side. Accordingly, the shapes of the three latch holes match the shape of the latch body 29, so that the latch body 29 can be prevented from rotating in the three latch holes; and the latch head 30 is exposed in the first latch hole; of course, the latch body 29 is inserted into and withdrawn from the three latch holes through the latch head 30.

[0091] On this basis, in order to avoid the top of the opening from interfering with the limiting boss 16, it is ensured that the limiting boss 16 can slide upward with the baffle 1 to the top of the inner slide groove on both sides of the opening; accordingly, Figure 4 and Fig.18 As shown, the top of the shielding shell 3 is provided with a second slot 18 that passes through the first side, the opening and the through slot. When the baffle 1 slides upward to the top of the inner slots on both sides of the opening, that is, when the shafts 28 on both sides of the baffle 1 slide to their tops along the inner slots on both sides of the opening, the limiting boss 16 can pass through the second slot 18 to ensure that the baffle 1 can be rotated around the shafts on both sides to a horizontal position for storage. In addition, in order to ensure the appearance of the shielding shell 3, accordingly, as shown in FIG. Figure 1 As shown, the camera device also includes a second buckle 6; Figure 2 As shown, the second buckle 6 is detachably connected to the second slot 18; in order to realize the convenient connection of the second buckle 6 to the second slot 18 from top to bottom, the second buckle 6 is connected to the second slot 18 using a staggered structure; wherein, Figure 1 As shown, the second buckle 6 is a clamping block, and the bottom ends of the two sides of the front side of the second buckle 6 are respectively provided with clamping grooves, and the two sides of the second clamping groove 18 are respectively provided with clamping strips, which are used to match the clamping grooves on the two sides of the front side of the second buckle 6 one by one, so that the second buckle 6 can be better clamped in the second clamping groove 18 from top to bottom. In addition, in order to facilitate the limit boss 16 to drive the second buckle 6 upward to disengage from the second clamping groove 18; accordingly, as shown in FIG. Figure 2As shown, the bottom of the second buckle 6 is provided with a second buckle plug-in boss 19, and the top of the limiting boss 16 is provided with a limiting boss groove 17 for cooperating with the second buckle plug-in boss 19, so that the baffle 1 can slide upward to the top of the inner slide groove. Fig.17 As shown, the limiting boss groove 17 of the limiting boss 16 is inserted into the second buckle plugging boss 19 of the second buckle 6, thereby driving the second buckle 6 to disengage from the second clamping groove 18 and rotate to a horizontal position together. In other words, this solution realizes the closing limit of the baffle 1 by combining the sliding grooves 20 on both sides of the opening, the first buckle 2 and the second buckle 6.

[0092] In addition, in order to achieve the closed snap connection of the baffle 1; accordingly, Fig.21 As shown, the bottom end of the back of the baffle 1 is provided with a third buckle 23 (i.e., the baffle back buckle), and when the baffle 1 slides to close the opening, as shown in FIG. Fig.19 As shown, the third buckle 23 of the baffle 1 is used to interfere with the slot, so as to achieve the closed engagement of the baffle 1; of course, in order to facilitate the release of the interference fit between the third buckle 23 and the slot, it is necessary to reserve a space at the bottom of the shielding shell 3 to pull the third buckle 23, so that the third buckle 23 can be pressed by a finger to disengage it from the slot; accordingly, as Fig. 20 As shown, a second groove 22 connected to the slot is formed at the bottom of the shielding shell 3 .

[0093] Furthermore, the camera device provided in the embodiment of the utility model further includes a bracket 10;

[0094] like Fig.12 As shown, a camera hood 31 is provided on one side of the camera body 7, and the other side is arranged in the shielding shell 3 through a bracket 10. That is, the camera consisting of the camera body 7 and the camera hood 31 is arranged in the shielding shell 3 through the bracket 10, thereby facilitating the modular connection between the camera and the shielding shell 3.

[0095] The structure of the bracket 10 can be referred to Fig.10 As shown, the bracket 10 is provided with two bracket positioning holes 35 and two bracket screw holes 34. Fig. 9 As shown, the back (rear side) of the camera body 7 is provided with two cameras and a bracket connecting positioning column 32 and two camera screw holes; Fig.12 As shown, the two cameras and the bracket connection positioning columns 32 are used to cooperate with the two bracket positioning holes 35 one by one to achieve the positioning assembly of the bracket 10 and the camera, and the two camera screw holes are connected to the two bracket screw holes 34 one by one through screws, such as Figure 1 As shown, the two screws are respectively the bracket and camera connecting screw 1 8 and the bracket and camera connecting screw 2 9.

[0096] In addition, if Figure 4 As shown, two BOSS columns 26 are provided inside the shielding shell 3 and are distributed on both sides of the opening, and each BOSS column 26 is fastened by a triangular support rib 27; Fig.10 As shown, bracket and shell connecting screw mounting holes 37 are respectively opened on both sides of the bracket 10, and the bracket and shell connecting screw mounting holes 37 on both sides of the bracket 10 are respectively connected to the two BOSS columns 26 of the shielding shell 3 by screws, as shown in FIG. Figure 1 and Fig.12 As shown, the two screws are respectively a bracket and housing connecting screw 11 and a bracket and housing connecting screw 2 12. Of course, if Fig.10 As shown, a bracket reinforcement rib 36 is designed at the bending part of the bracket 10 to ensure that the ear is bent vertically, so as to facilitate the connection between the bracket 10 and the shielding shell 3.

[0097] In addition, in order to facilitate the assembly connection between the shielding shell 3 and the rearview mirror in the cabin; accordingly, Figure 4 As shown, the second side portion (which may be the rear side portion) of the shielding shell 3 is distributed relative to the first side portion, and the second side portion of the shielding shell 3 is an open structure, and a group of diagonal portions of the end surface of the second side portion of the shielding shell 3 are respectively provided with shell positioning columns 15, and another group of diagonal portions are respectively provided with shell screw mounting holes 24, and a group of opposite sides of the end surface of the second side portion of the shielding shell 3 are respectively provided with shell buckles 25; that is, the end surface of the second side portion of the shielding shell 3 is provided with the above-mentioned installation positioning connection structure for cooperation with the rearview mirror in the cabin, and the shielding shell 3 is assembled and positioned and connected with the rearview mirror in the cabin through the above-mentioned structure; of course, the rearview mirror in the cabin also needs to be respectively provided with corresponding structures for cooperating with the above-mentioned structures, which will not be repeated here. In this way, it is helpful to realize the modular connection between the shielding shell 3 and the rearview mirror in the cabin, and it is also convenient for the assembly and disassembly of the shielding shell 3.

[0098] At the same time, in order to better understand the camera device of this solution, its working principle and assembly process are introduced as follows:

[0099] Working principle of this camera device:

[0100] When in daytime working mode, the camera is in RGB state, at which time the IR-LED is turned off and natural light is used for fill light. Natural light passes through the lens to project light information onto the sensor of the camera to realize the conversion of photoelectric signals. The electrical signal is processed by the ISP module inside the camera, and the video signal is output to the vehicle computer through the camera fakra21 to realize the recognition of passenger information. At this time, the baffle of the shielding shell is in the open state; when in night working mode, the camera is in IR state, at which time the IR-LED is turned on, infrared light shines on the passenger, and the infrared light information is reflected through the lens and hits the sensor. Similarly, the output and recognition of passenger behavior information is realized; the black foam inside the camera hood blocks excessive LED light to prevent the LED light from shining on the ceiling and reading light in the cabin, thereby avoiding overexposure of the picture; when the red exposure of the IR-LED at night is too obvious and causes discomfort to passengers and drivers, the shielding shell can be closed to prevent the red exposure from appearing in the field of vision of passengers and drivers.

[0101] The assembly process of this camera device:

[0102] The first step is to stick the first foam and the second foam to the designated position on the back of the camera visor 31, such as Figure 7 As shown, the camera hood 31 is snapped onto the camera body 7 to complete the assembly of the camera part; the second step is to achieve the positioning and connection of the bracket 10 and the camera body 7 through the cooperation of the positioning column on the back of the camera and the positioning hole of the bracket, and the screw connection of the threaded hole on the back of the camera and the bracket; the third step is to achieve the connection of the bracket 10 and the shell 3 through the screw connection of the mounting ear of the bracket 10 and the shell BOSS column 26 (that is, the shell screw column); in this way, the assembly of the camera and the shielding shell 3 is completed, as shown in FIG. Fig.12 As shown; the fourth step is to insert the baffle 1 along the slide groove 20 and slide it until the back buckle of the baffle is tightly attached to the second groove 22 of the shell, and the first buckle 2 is tightly attached to the positioning boss (i.e., the limiting boss 16) of the baffle 1, and the latch 13 is inserted into the circular pin hole (i.e., the first latch hole, the third latch hole, and the second latch hole) to realize the assembly of the baffle 1 and the shielding shell 3, as shown in FIG. Fig.11 and Figure 2As shown, similarly, pull out the latch 13 to separate the baffle 1 and the shielding shell 3; the fifth step is to connect the shell positioning column 15 and the shell buckle 25 of the shielding shell to the rearview mirror part in the vehicle cabin, and realize the fastening connection between the shielding shell 3 and the rearview mirror part in the vehicle cabin through the shell threaded hole 24; the assembly of the camera and the shielding shell in the cabin is completed; the sixth step is that when the OMS camera needs to monitor the passengers, press the buckle on the back of the baffle to push the positioning boss of the baffle upward, and when the baffle 1 slides to the top of the shielding shell, the second buckle 6 is inserted into the limiting boss groove 17 of the positioning boss. At this time, the baffle 1 can be rotated around the round pin (i.e., the rotating shaft 28) and fall into the upper groove (i.e., the first groove 14) of the shielding shell, reducing the space occupied, as shown in FIG. Fig.16 and 17 As shown; similarly, the baffle 1 can cover the camera in reverse to play a shielding role.
